Description

INTEGRATED APPARATUS FOR ELECTRONIC OPENING AND CLOSING OF VEHICLE DOOR

The present invention relates to an integrated apparatus for electronic opening and closing of a vehicle door, and more particularly, to an apparatus in which a hidden handle, an electronic latch, and a cinching module which are required for the electronic opening and closing of the vehicle door are integrated.

In the interior and exterior of a vehicle door, a door latch for performing door locking and unlocking operations and door opening and closing operations, an inside handle and an outside handle for the door opening operation, a door lock mechanism that enables the door locking and unlocking operations using a key or a button, a safety knob for manually controlling a door lock state, and the like are provided.

Generally, when a driver inserts a vehicle key into a key cylinder 4 (refer to FIG. 2) of the door lock mechanism and rotates the key, a rotary force thereof is transmitted to the door latch by a mechanical and circuital connection structure such that the door locking and unlocking operations are performed.

Alternatively, the door locking and unlocking operations may be performed by a driver pressing a button of a remote controller (a key fob), or, for a vehicle to which a personal identification card (PIC) system is applied, when a driver approaches the vehicle while holding a smart key, the door lock may be released and the driver may immediately open the door.

Alternatively, while holding a smart key, a driver may press a button of an outside handle to release the door lock and then pull the outside handle to open the door.

Also, when the outside handle is operated in a state in which the door lock is released by the door latch, i.e., a state in which the door is unlocked, an operation force of the handle may be transmitted to the door latch via a cable (or a rod) connected between the outside handle and the door latch, and a door opening operation (an operation in which restraint of a striker installed in a vehicle body is released) of the door latch may be performed. Thus, the user is able to open the door.

Since the mechanical connection structure between the outside handle and the door latch that allows the door to be opened in the state in which the door is unlocked is a known art, description thereof will be omitted.

Meanwhile, when an electronic hidden handle is applied as the outside handle, a motor configured to rotate the handle is provided. The motor at a side of the handle is for withdrawing the handle to the outside of a door panel so that the handle is operated only when the door lock is released and for storing the handle inside the door panel so that the handle is not withdrawn when not in use. When the door is locked, the handle is disposed so as not be withdrawn from the door panel.

When a driver operates a remote controller to unlock the door or a driver holding a smart key approaches the vehicle, the motor is driven to cause the handle to protrude to the outside of the door panel so that the handle may be pulled.

FIG. 1 is a view illustrating an electronic retractable handle of the present invention. FIG. 1A illustrates a state in which a handle 2 is inserted into a door panel 1 so that the handle 2 does not protrude to the outside of the door panel 1; FIG. 1B illustrates a state in which the handle 2 is withdrawn to the outside of the door panel 1 so that the handle 2 may be pulled; and FIG. 1C illustrates a state after the handle 2 is pulled by the user.

As illustrated, the handle 2 is inserted into a mounting portion of the door panel 1 such that the handle 2 does not protrude from a surface of the door panel, and then the handle 2 slides forward by an inner motor 3 (not illustrated) and is withdrawn to the outside of the door panel 1 so that the driver may operate the handle 2.

An electronic hidden handle and a door latch structure of the related art have been proposed in Korean Patent Registration No. 10-1637820. FIG. 2 is a schematic diagram illustrating an electronic retractable handle and a door latch of the related art and is a view illustrating a state in which a handle 2 is stored by a motor 3 and a state in which the handle 2 protrudes by the motor 3. FIG. 2A illustrates a state in which the handle 2 is stored so as not to protrude to the outside, and FIG. 2B illustrates a state in which the motor 3 is operated to cause the handle 2 to protrude to the outside so that the handle 2 may be pulled.

Even when such an electronic retractable handle is applied, when a vehicle key is inserted into a key hole of a door lock mechanism and the key is rotated, a rotary force thereof is transmitted to a door latch 5 such that door locking and unlocking operations may be performed.

Also, when a driver presses a button of a remote controller (not illustrated) or approaches the vehicle while holding a smart key, locking and unlocking of the door may be performed by an electronic actuator 6 including a motor inside the door latch 5. Here, since the door latch has its own actuator 6, the door locking and unlocking operations may be performed independently of the withdrawal of the handle.

However, the handle 2 and the door latch 5 are mechanically connected via a cable 7 or electrically connected via a wire or the like, and the cable 7 is used for the door opening operation.

That is, when, by the motor 3 at a side of the handle 2, the handle is withdrawn, when the user pulls the handle in the state in which the door is unlocked, an operation force of the handle is transmitted to the door latch 5 via the cable 7, and thus the door latch 5 connected to the handle by the cable 7 is operated such that the door is opened.

A reduction gear is connected to the motor 3 for withdrawing the handle 2. The reduction gear receives power of the motor 3. Also, the reduction gear transmits power to a system that withdraws the handle.

However, in the technology of Korean Patent Registration No. 10-1637820, only the locking and unlocking of the door are electrically performed by the electronic actuator 6, and the opening of the door is mechanically performed by the cable 7. A technology in which the door opening operation is also performed electrically so that the door opening operation is more easily performed than when using a mechanical means has been proposed in Korean Patent Registration No. 10-0256175.

In Korean Patent Registration No. 10-0256175, a detection sensor switch 80 in which an electric contact is connected and disconnected by operation of a latch gear 20 is included. The detection sensor switch 80 serves to disconnect power and prevent the latch gear 20 from rotating further in a state in which the latch gear 20 is open. However, the detection sensor switch 80 has a problem in that, in a state in which the latch gear 20 is closed, it is not capable of preventing a phenomenon in which, due to an occurrence of an electrical malfunction, the latch gear 20 is opened while the vehicle is running. There are problems in that there is no means to prevent an electrical malfunction while the vehicle is running and there is no means to prevent the latch gear 20 from opening when the electrical malfunction occurs while the vehicle is running.

Also, as proposed in Korean Patent Publication No. 10-2008-0061625, in a vehicle door latch system, functions of an opening motor that opens a door and a cinching motor that completely locks the door when the door is not completely locked are integrated into a single device so that the cinching function may be performed using a single motor.

However, such a conventional vehicle door latch system has a problem in that, since it is not possible to change an actuator according to the type of vehicle, it is not possible to sufficiently supply a driving force necessary for each vehicle in order to perform the cinching function.

A door latch of a vehicle trunk lid in which an actuator is separated has been proposed in Korean Patent Registration No. 10-1308495.

However, convenience of using such a conventional door latch is decreased because it is difficult for a customer to couple and separate the actuator according to whether the cinching function is added. Also, since a driving force of the actuator is transmitted to a claw lever, which locks a striker, via various parts, there are problems in that the number of parts is increased, the manufacturing cost is increased, the assembly process becomes complicated, and the volume also increases.

Thus, the latch portion 2000 may be easily and firmly installed at the panel 10.

A cut portion corresponding to the striker insertion groove 2105 is formed in the second housing 2130 so that the striker insertion groove 2105 is open forward.

The second housing 2130 is installed at the front surface of the first housing 2110 via a plurality of bolts or the like.

In the second housing 2130, holes into which bolts are fastened are disposed at upper and lower portions of the left side and upper and lower portions of the right side with respect to the striker insertion groove 2105.

The third housing 2150 is illustrated in detail in FIGS. 28 and 29.

The third housing 2150 is formed in a plate shape whose edge protrudes to the front so that a space is formed at a front surface. The space of the third housing 2150 is formed to be open forward.

The third housing 2150 covers the rear surface of the first housing 2110 which is the opposite surface of the surface at which the latch 2200 is installed. That is, the second housing 2130 is coupled to the front surface of the first housing 2110, and the third housing 2150 is coupled to the rear surface of the first housing 2110.

The third housing 2150 is bolted and fastened to the rear surface of the first housing 2110.

First and

second fastening portions

2121 and 2155 for bolting and fastening are respectively formed at the rear surface of the first housing 2110 and the third housing 2150.

The first fastening portion 2121 formed at the first housing 2110 is formed in the shape of a boss so as to protrude to the rear. The front of a hole into which a bolt is fastened that is formed in the first fastening portion 2121 is blocked. A rear end of the first fastening portion 2121 is formed to protrude further to the rear than the edge of the first housing 2110. Screw threads are formed at an inner circumferential surface of the first fastening portion 2121. The first fastening portion 2121 is disposed at both sides of the upper portion and both sides of the lower portion of the first housing 2110. A guide boss 2122 is formed at an upper portion of the right side of the first housing 2110 so as to protrude to the rear. The guide boss 2122 is disposed further to the left than the first fastening portion 21212 at the right side. The guide boss 2122 is inserted into a through-hole of a worm gear 2614 which will be described below.

The second fastening portion 2155 formed at the third housing 2150 is formed in the shape of a through-hole penetrating in the front-rear direction. The second fastening portion 2155 is disposed to correspond to the first fastening portion 2121.

A fourth-and-fifth sensor installation portion 2151a and a sixth sensor installation portion 2151b are formed at a lower portion of the third housing 2150. The fourth-and-fifth sensor installation portion 2151a and the sixth sensor installation portion 2151b are formed to be open forward and upward, insert terminal wires are disposed at lower portions of the fourth-and-fifth sensor installation portion 2151a and the sixth sensor installation portion 2151b, and the wires are connected to fourth, fifth, and

sixth sensors

2901, 2902, and 2903 through the grooves of the fourth-and-fifth sensor installation portion 2151a and the sixth sensor installation portion 2151b.

A fourth protruding portion 2152 and a fifth protruding portion 2153a are formed at the central portion of the third housing 2150 so as to protrude to the front.

The fourth protruding portion 2152 is formed in a circular shape. The center of the fourth protruding portion 2152 and the center of the insertion hole 2535 of the lever 2530 coincide with each other. The fourth protruding portion 2152 comes into contact with the rear surface of the lever 2530. Therefore, during assembly, friction between the lever 2530 and the third housing 2150 may be minimized while the lever 2530 does not move in the front-rear direction.

The fifth protruding portion 2153a is formed to be curved in the rotating direction of the lever 2530. The fifth protruding portion 2153a comes into contact with the rear surface of the lever 2530. Therefore, during assembly, friction between the lever 2530 and the third housing 2150 may be minimized while the lever 2530 does not move in the front-rear direction.

A lever guide portion 2153b is disposed at left and right sides below the fifth protruding portion 2153a. The lever guide portion 2153b is formed to be recessed from the front to the rear. A catching member fitting portion 2531 of the lever 2530 and the fixing portion 2522 of the cinching connecting portion 2520 are inserted into the lever guide portion 2153b. A right side of the lever guide portion 2153b is formed to be curved in the rotating direction of the catching member fitting portion 2531. A radius of rotation of the lever 2530 is limited by the catching portion guide groove 2115 and the lever guide portion 2153b. A left side of the lever guide portion 2153b is formed in a linear shape so that the fixing portion 2522 may be assembled in the left-right direction.

A connecting portion cover installation groove 2156 is formed at the upper portion of the third housing 2150. The connecting portion cover installation groove 2156 is formed to be open rightward and forward. A connecting portion cover support portion 2157 is formed to protrude at upper and lower portions and a left side of the connecting portion cover installation groove 2156. Due to the connecting portion cover support portions 2157, when installing the connecting portion cover 2800 in the connecting portion cover installation groove 2156, friction is minimized and thus the installation is facilitated. The connecting portion cover support portion 2157 formed at the lower portion fixes the connecting portion cover 2800, prevents the open plate 2300 and the safety plate 2400 from falling off, and guides sliding of the open plate 2300 and the safety plate 2400 in the left-right direction. Since the upper portion of the right side of the connecting portion cover installation groove 2156 is blocked, the connecting portion cover 2800 is prevented from moving in the left-right direction. Since a rear portion of the connecting portion cover installation groove 2156 is blocked, the connecting portion cover 2800 is prevented from moving in the front-rear direction.

A first sensor installation portion 2151c at which a first sensor 2907 is installed is formed at the upper portion of the left side of the third housing 2150. The first sensor installation portion 2151c is disposed at the right side of the connecting portion cover installation groove 2156. The first sensor installation portion 2151c is formed to be open forward and upward. Since a protrusion is formed at a lower portion of the first sensor installation portion 2151c, friction generated when installing the first sensor 2907 is minimized. Also, an insert terminal wire is disposed at the lower portion of the first sensor installation portion 2151c, and the wire is connected to the first sensor 2907. Since a protrusion is formed at an upper portion of a left side of the first sensor installation portion 2151c so as to protrude to the right side, the first sensor 2907 is prevented from moving in the up-down direction. Also, since an upper surface of the protrusion is formed to come into contact with the lower surface of the safety plate 2400, the protrusion may guide sliding of the safety plate 2400 in the left-right direction. A protrusion that may be fitted into a groove formed in the first sensor 2907 is formed at the center of the first sensor installation portion 2151c. Due to the protrusion, the first sensor 2907 is prevented from moving in the up-down and left-right directions.

A third step guide portion 2158 is formed at the upper portion of the right side of the third housing 2150 so that, when a third step 2730 of the open lever 2700 moves within the radius of rotation, the third step 2730 does not interfere with the third housing 2150. The third step guide portion 2158 is disposed at the lower portion of the left side of the first sensor installation portion 2151c. The third step guide portion 2158 is formed to be recessed in the shape of an arc that is convex upward. Thus, the third step 2730 rotates within a range between a left end and a right end of the arc.

Connecting portion through-

grooves

2159a and 2159b are formed at the upper and lower portions of the left side of the third housing 2150 so as to be open forward, leftward, and rightward.

The door latch connecting portion 30, the door lever connecting portion 40, and the door key connecting portion 50 are installed in the connecting portion through-groove 2159a at the upper portion. The connecting portion through-groove 2159a at the upper portion comes into communication with the connecting portion cover installation groove 2156.

The cinching connecting portion 2520 is installed in the connecting portion through-groove 2159b at the lower portion. The connecting portion through-groove 2159b at the lower portion comes into communication with the lever guide portion 2153b.

The wire connecting portion 2154 is formed at the upper portion of the right side of the third housing 2150 so as to protrude from the front to the rear. The wire connecting portion 2154 comes into communication with the connecting portion cover installation groove 2156. A wire is inserted into an insert terminal inside the third housing 2150 and is connected to the outside and installed inside the third housing 2150 through the wire connecting portion 2154.

A rib is formed in a lattice shape at the rear surface of the third housing 2150. Thus, durability of the third housing 2150 may be improved.

<Latch>

The latch 2200 is illustrated in detail in FIG. 30.

The latch 2200 is installed in the first housing 2110 so as to be disposed inside the latch installation groove 2111.

The latch 2200 is rotatably installed in the first housing 2110 through the latch pivoting shaft 2230 isntalled in the second housing 2130.

The latch 2200 is formed in a plate shape.

A locking groove 2201 is formed in an outer circumferential surface of the latch 2200.

The locking groove 2201 is formed to be penetrated in the front-rear direction and have an open outer end.

Due to such a locking groove 2201, a second locking catching portion 2201a, which will be described below, at which a locking portion 2371 of the pivoting member 2370 is caught is formed at the latch 2200.

The locking groove 2201 has a width that gradually increases from the inside to the outside.

The locking groove 2201 is surrounded by a first surface 2203, a second surface 2205 which extends from a left side end of the first surface 2203 and is formed to be inclined, and a third surface 2207 which extends from a left side end of the second surface 2205 and is formed in an arc shape so as to surround the striker.

The first surface 2203 forms an upper surface of the second locking catching portion 2201a.

A striker catching protrusion 2204 at which the striker is caught is formed at the latch 2200.

The striker catching protrusion 2204 is disposed inside the locking groove 2201 so that the striker is effectively prevented from falling off after being inserted into the locking groove 2201.

The striker catching protrusion 2204 is formed at a surface facing a surface at which the first surface 2203 is formed (a surface at which the locking portion 2371 is caught).

Since a surface of the striker catching protrusion 2204 that faces the striker when the striker is inserted into the locking groove 2201 and a surface of the striker catching protrusion 2204 that faces the striker when the striker is withdrawn from the locking groove 2201 are formed to be inclined, the striker may be smoothly inserted into the locking groove 2201.

An auxiliary locking groove 2202 is formed at a lower portion of the locking groove 2201 in the latch 2200. The auxiliary locking groove 2202 is formed in a shape similar to that of the locking groove 2201 while having a shallower depth than that locking groove 2201. That is, a distance between the auxiliary locking groove 2202 and the center of rotation of the latch 2200 is larger than a distance between the locking groove 2202 and the center of rotation of the latch 2200.

When closing the panel 10, the locking portion 2371 is inserted into the auxiliary locking groove 2202 at first and then inserted into the locking groove 2201.

The locking groove 2201 and the auxiliary locking groove 2202 are disposed to be spaced apart from each other in a circumferential direction. Thus, a passenger may recognize the process in which the panel 10 is being closed by the motor 2610. Also, even when locking is not performed in the locking groove 2201, since the auxiliary locking groove 2202 holds the panel 10, there is an advantage in that safety of locking is improved.

Meanwhile, due to such an auxiliary locking groove 2202, a first locking catching portion 2202a, which will be described below, at which the locking portion 2371 is caught is formed in the latch 2200.

Further, the latch 2200 is surrounded by an elastic cover 2206. The elastic cover 2206 is formed of a material having elasticity such as rubber and serves to absorb impact applied to the latch 2200 and prevent noise. The elastic cover 2206 is formed to surround the entire latch 2200.

A slit 2209 is formed in the elastic cover 2206. In the latch 2200, the slit 2209 is formed in a portion abutting the bumper member 2360 which is disposed at the upper portion, a portion abutting the striker, a portion abutting the first restoring spring catching shaft 2251, and the like. When the latch 2200 abuts another member, impact may be absorbed due to such slits 2209.

Further, a friction protrusion 2208 is formed at the elastic cover 2206. The friction protrusion 2208 is disposed near each of a protrusion 2215 and a spring fitting portion 2213. The friction protrusion 2208 is formed to protrude to the front and abuts the second housing 2130. When the latch 2200 is restored by the first restoring spring, a rotational speed of the latch 2200 is adjusted due to friction between the friction protrusion 2208 and the second housing 2130. Thus, the door may be smoothly opened.

The spring fitting portion 2213 is formed at the outer circumferential surface of the latch 2200.

The spring fitting portion 2213 is formed in the shape of a groove or a hole. In the present embodiment, the spring fitting portion 2213 is formed in the shape of a groove.

The protrusion 2215 is formed at an outer circumferential surface of a left side of the latch 2200 so as to protrude to the outside.

The protrusion 2215 is disposed at the front of the catching portion guide groove 2115.

The locking groove 2201, the auxiliary locking groove 2202, the spring fitting portion 2213, and the protrusion 2215 are disposed in that order in a direction (clockwise) in which the latch 2200 rotates while the panel 10 is closed.

The first restoring spring 2250 is provided so that the latch 2200 is automatically restored when the locking is released.

First and second

bent portions

2252 and 2253 which are bent corresponding to the shape of an assembly portion are formed at one end and the other end of the first restoring spring 2250. For example, the first bent portion 2252 is bent upward at a right angle, and the second bent portion 2253 is bent forward at a right angle.

The first bent portion 2252 of the first restoring spring 2250 is caught at the first restoring spring catching shaft 2251, a coil portion of the first restoring spring 2250 is wound around the latch pivoting shaft 2230, and the second bent portion 2253 is fitted into the spring fitting portion 2213 of the latch 2200. Since the first and second

bent portions

2252 and 2253 are formed at the first restoring spring 2250 in this way, assemblability is further improved.

When the latch 2200 rotates, the other end of the first restoring spring 2250 is rotated together with the latch 2200.

<Pivoting member>

The pivoting member 2370 is illustrated in detail in FIG. 31. The pivoting member 2370 is also referred to as "pawl."

The pivoting member 2370 interlocks with the open lever 2700.

The pivoting member 2370 is disposed at the front side of the first housing 2110 and is pivotally installed in the second housing 2130 by the pivoting shaft 2380 disposed in the front-rear direction.

The pivoting shaft 2380 is installed to pass through the upper portion of the pivoting member 2370.

A rivet is provided as the pivoting shaft 2380, and the pivoting shaft 2380 is riveted in the second housing 2130.

The pivoting member 2370 may pivot clockwise or counterclockwise about the pivoting shaft 2380.

Also, the pivoting member spring 2390 configured to restore the pivoting member 2370 may be provided.

Like the first restoring spring 2250, the pivoting member spring 2390 is also a coil spring, and first and second

bent portions

2392 and 2393 which are bent corresponding to the shape of the assembly portion are formed at both ends of the pivoting member spring 2390. For example, the first bent portion 2392 is bent upward at a right angle, and the second bent portion 2393 is bent forward at a right angle.

The first bent portion 2392 of the pivoting member spring 2390 is supported and fixed by the pivoting spring catching shaft 2391 which is riveted in the second housing 2130, and the second bent portion 2393 is caught and connected at a spring fitting portion 2375 formed at the right side of the pivoting member 2370. A coil portion of the pivoting member spring 2390 is fitted to the pivoting shaft 2380.

The spring fitting portion 2375 may be formed in the shape of a groove or a hole. In the present embodiment, the spring fitting portion 2375 is formed in the shape of a groove.

When a force is applied to the pivoting member 2370 such that the pivoting member 2370 is pushed counterclockwise and then released, the pivoting member spring 2390 serves to allow the pivoting member 2370 to be restored to its default position by giving an elastic force that causes the pivoting member 2370 to pivot clockwise.

The pivoting member 2370 is formed of the locking portion 2371 and a catching protrusion 2373.

The locking portion 2371 is formed at a lower portion of a left side of the pivoting member 2370 so as to protrude to the left side.

The locking portion 2371 serves to restrict (lock) the position of the latch 2200, thereby allowing the closed state of the panel 10 to be maintained.

A latch insertion groove 2372 into which a portion (the first surface 2203) of an end of the latch 2200 is inserted while the panel 10 is closed is formed in the lower portion of the locking portion 2371. The latch insertion groove 2372 is formed to be open downward and is disposed between the locking portion 2371 and the catching protrusion 2373. Due to such a latch insertion groove 2372, the state in which the latch 2200 is locked to the pivoting member 2370 is stably maintained while the panel 10 is closed.

The catching protrusion 2373 is formed at the right side of the lower surface of the locking portion 2371 so as to protrude downward.

A pivoting member catching portion 2711 of the open lever 2700 is inserted into a left side of the catching protrusion 2373. That is, the catching protrusion 2373 serves to cause the pivoting member 2370 to pivot according to rotation of the open lever 2700.

The pivoting member 2370 is rotated by interlocking with rotation and movement of the open lever 2700.

Also, as in the latch 2200 described above, an elastic cover 2374 is also provided at the pivoting member 2370. The elastic cover 2374 is formed of a material having elasticity such as rubber and serves to absorb impact applied to the pivoting member 2370 and prevent noise. The elastic cover 2374 is formed to surround the entire pivoting member 2370.

A slit 2376 is also formed in the elastic cover of the pivoting member 2370. In the pivoting member 2370, the slit 2376 is formed in a portion abutting the open lever 2700. Specifically, the slit 2376 is disposed between the locking portion 2371 and the catching protrusion 2373. When the pivoting member 2370 is restored by the pivoting member spring, even when the pivoting member 2370 and the open lever 2700 abut each other, impact is absorbed by the slit 2376.

<Open lever>

The open lever 2700 is illustrated in detail in FIG. 31.

The open lever 2700 is rotatably installed at the shaft 2106 formed at the rear surface of the first housing 2110. That is, the open lever 2700 is installed at the opposite surface of the surface at which the latch 2200 is installed in the housing 2100.

The open lever 2700 is formed of a first step 2710, a second step 2720, and the third step 2730. The first step 2710, the second step 2720, and the third step 2730 are formed to be separable from each other. The first step 2710, the second step 2720, and the third step 2730 are installed so that a front surface of the second step 2720 abuts a rear surface of the first step 2710 and a front surface of the third step 2730 abuts a rear surface of the second step 2720.

The first step 2710 is formed in a plate shape. The pivoting member catching portion 2711 configured to abut the left side of the catching protrusion 2373 of the pivoting member 2370 is formed at a front surface of the first step 2710 so as to protrude to the front. The pivoting member catching portion 2711 is exposed to the front through the pivoting member catching portion through-hole 2118.

A detecting portion 2712 at which lower portions of the second step 2720 and the third step 2730 are caught is formed at the rear surface of the first step 2710 so as to protrude to the rear. The detecting portion 2712 is formed to be able to press the sixth sensor 2903 installed below the detecting portion 2712.

A front side of the second step 2720 is formed in the shape of a plate that is disposed at a lower portion of a hole into which the shaft 2106 is fitted. Portions of the front side of the second step 2720 that are adjacent to the hole are formed to protrude to the front so that a contact area between the first step 2710 and the second step 2720 is decreased. Thus, friction between the first step 2710 and the second step 2720 may be minimized.

A rear side of the second step 2720 is formed in the shape of a plate that is disposed at an upper portion of the hole and bent in a stair shape. A lower portion of the rear side of the second step 2720 is formed in an arc shape along the hole.

A second step protrusion 2722 is formed at a left side of a lower portion of the second step 2720 so as to protrude to the lower side, and a first detecting portion insertion groove 2721 into which the detecting portion 2712 is inserted is formed in a right side of the second step protrusion 2722.

A second step catching portion 2723 inserted between first and second

rotation catching portions

2617 and 2618 of a locking member 2615 is formed at an upper portion of the second step 2720. Thus, when the locking member 2615 rotates and thus the second step 2720 rotates, the first step 2710 also rotates as a result.

The third step 2730 is formed in the shape in which a lower side is bent forward in a stair shape and an upper side is bent rearward in a stair shape with respect to the portion where the hole into which the shaft 2106 is fitted is formed. A second step guide portion 2734 into which the rear side of the second step 2720 is inserted is formed at an upper portion of the lower side of the third step 2730. The second step guide portion 2734 is formed so that an upper portion is formed in an arc shape corresponding to the shape of the rear side of the second step 2720 and a front surface is formed to protrude to the front, thereby minimizing friction between the second step 2720 and the third step 2730.

A third step protrusion 2732 is formed at a left side of a lower portion of the third step 2730 so as to protrude to the lower side, and a second detecting portion insertion groove 2731 into which the detecting portion 2712 is inserted is formed in a right side of the third step protrusion 2732.

A third step catching portion 2733 which is inserted into a third step fitting groove 2304 of the open plate 2300 is formed at an upper portion of the third step 2730. Thus, when the open plate 2300 slides and thus the third step 2730 rotates, the first step 2710 also rotates as a result.

<Driving portion>

The driving portion is illustrated in detail in FIGS. 32 and 33.

The driving portion includes the motor 2610, the worm gear 2614 rotated by the motor 2610, the locking member 2615 configured to simultaneously rotate with the worm gear 2614, and the safety plate 2400 inserted into the locking member 2615.

The driving portion is disposed at the upper portion of the rear of the first housing 2110. The driving portion is disposed between the first housing 2110 and the third housing 2150.

A worm 2613 is installed at the shaft of the motor 2610.

The worm 2613 is engaged with the worm gear 2614. The worm gear 2614 is disposed at an upper portion of the worm 2613.

The worm gear 2614 and the locking member 2615 are integrally formed. The locking member 2615 is formed at the rear of the worm gear 2614.

A safety plate fitting groove 2616 into which a locking fitting portion 2403 of the safety plate 2400 that will be described below is inserted is formed in an upper portion of the locking member 2615. Two rotation catching portions at which the second step 2720 of the open lever 2700 is caught are formed at both sides of a lower portion of the locking member 2615 so as to be spaced apart from each other in the circumferential direction.

The rotation catching portions include a first rotation catching portion 2617 and a second rotation catching portion 2618.

Due to such rotation catching portions, when the locking member 2615 is rotated, the second step 2720 is rotated clockwise or counterclockwise.

<Safety plate>

The safety plate 2400 is illustrated in detail in FIGS. 32 and 33.

The safety plate 2400 is formed in the shape of a quadrilateral bar.

A safety plate detection protrusion 2402 is formed at a right side of the safety plate 2400 so as to protrude to the lower side. Due to the safety plate detection protrusion 2402, the safety plate 2400 is detected by the first sensor 2907 that applies electricity during withdrawal of the outer handle 1800.

The locking fitting portion 2403 inserted into the locking member 2615 is formed at the central portion of the safety plate 2400 so as to protrude to the lower side. While the outer handle 1800 is inserted, the locking fitting portion 2403 is inserted into the safety plate fitting groove 2616 of the locking member 2615 so that rotation of the locking fitting portion 2403 is restricted.

A stopper installation portion 2410 at which the door latch connecting portion 30 is installed is formed at the left side of the safety plate 2400. The stopper installation portion 2410 is formed to protrude further downward than other portions of the safety plate 2400.

The stopper installation portion 2410 includes a cover fitting portion 2401, a stopper fitting groove 2411, a stopper catching portion 2412, and a spring fitting portion 2413.

The cover fitting portion 2401 is formed to protrude upward at both front and rear sides of an upper portion of the stopper installation portion 2410. The cover fitting portion 2401 is inserted into the connecting portion cover 2800, thereby preventing the safety plate 2400 from moving in the front-rear direction and limiting the sliding width of the safety plate 2400 in the left-right direction.

The stopper fitting groove 2411 is formed to be open upward. The stopper 34 of the door latch connecting portion 30 is fitted into the stopper fitting groove 2411, and a left-right length of the stopper fitting groove 2411 is formed to be larger than the left-right length of the stopper 34 so that the stopper 34 may slide in the left-right direction. Thus, even when the cable 33 is bent and thus the stopper 34 moves or when a stroke error occurs during assembly of the door latch connecting portion 30, it is possible to actively deal with such situations.

The stopper catching portion 2412 is formed to be open upward and have a right side that comes into communication with the left side of the stopper fitting groove 2411. That is, the stopper catching portion 2412 is disposed at the left side of the stopper fitting groove 2411. The cable 33 of the door latch connecting portion 30 is installed at the stopper catching portion 2412.

The cover fitting portion 2301 is formed to protrude upward at both front and rear sides of an upper portion of the stopper installation portion 2310. The cover fitting portion 2301 is inserted into the connecting portion cover 2800, thereby preventing the open plate 2300 from moving in the front-rear direction and limiting the sliding width of the open plate 2300 in the left-right direction.

The stopper fitting groove 2311 is formed at both sides in the front-rear direction so as to be open upward. A stopper 44 of the door lever connecting portion 40 and a stopper 54 of the door key connecting portion 50 are respectively fitted into the stopper fitting grooves 2311, and a left-right length of the stopper fitting grooves 2311 is formed to be larger than a left-right length of the

stoppers

44 and 54 so that the

stoppers

44 and 54 may slide in the left-right direction. Thus, even when a cable 43 and the cable 53 are bent and thus the

stoppers

44 and 54 move or when a stroke error occurs during assembly of the door lever connecting portion 40 and the door key connecting portion 50, it is possible to actively deal with such situations.

The stopper catching portions 2312 are formed to be open upward and have a right side that comes into communication with the left side of each stopper fitting groove 2311. That is, the stopper catching portion 2312 is disposed at the left side of each stopper fitting groove 2311. The cable 43 of the door lever connecting portion 40 and the cable 53 of the door key connecting portion 50 are respectively installed at the stopper catching portions 2312. A front-rear width of the stopper catching portions 2312 is formed to be smaller than a front-rear length of the

stoppers

44 and 54 so that the

stoppers

44 and 54 are prevented from falling off to the left side from the stopper fitting grooves 2311.

The spring fitting portion 2313 is formed at both sides in the front-rear direction at the left side of the stopper installation portion 2310 so as to protrude to the left side. A stopper spring 45 of the door lever connecting portion 40 and a stopper spring 55 of the door key connecting portion 50 are respectively installed at the spring fitting portions 2313.

A groove is formed in the spring fitting portion 2313 so as to be open upward. A front-rear width of the groove is equal or similar to the front-rear width of the stopper catching portion 2312, and the groove comes into communication with the stopper catching portion 2312.

When a lever connected to the door lever connecting portion 40 is pulled or a key is inserted into the key cylinder 1600 and rotated such that the door key connecting portion 50 is pulled in case of emergency where a motor has failed or power is not supplied, the open plate 2300 slides such that the door is open. The lever may be disposed only at a driver's seat without being disposed at a passenger seat and a backseat.

The catching member fitting portion 2531 is inserted into a lever groove formed in the front of the third housing 2150. The lever groove is formed to be curved in a rotating direction of the lever 2530.

The latch catching portion 2532 is formed at a left side of the lever 2530 so as to protrude to the front. The latch catching portion 2532 is formed to be curved along the circumferential shape of the lever 2530. A latch catching portion protrusion 2533 may be formed to protrude from a lower portion of the latch catching portion 2532. A sensor capable of detecting the latch catching portion protrusion 2533 may be further provided so that a position of the lever 2530 may be detected. Separately, the latch catching portion 2532 interlocks with the actuator 2510 such that it is possible to control a cinching stroke inside the actuator 2510 itself.

The lever protrusion 2534 is formed as an arc-shaped plate and may minimize friction between the lever 2530 and the first housing 2110.

<Outer handle withdrawal process>

Hereinafter, a process in which the outer handle 1800 is withdrawn will be described.

FIG. 19 illustrates a state in which the outer handle 1800 is withdrawn.

When an instruction to withdraw the outer handle 1800 is input through a key, a remote controller, a switch, or the like, the control portion operates the driving portion 1900.

When the motor 1910 is operated, the worm 1921 rotates. As the worm 1921 rotates, the first double gear 1922 rotates. As the first double gear 1922 rotates, the second double gear 1925 rotates. As the second double gear 1925 rotates, the lead screw 1929 rotates.

When the lead screw 1929 rotates, the support plate 1930 moves leftward.

When the support plate 1930 moves leftward, the lift 1300 inserted into the support plate 1930 also moves leftward.

When the lift 1300 moves leftward, the first and

second pins

1401 and 1402 disposed in the slots 1301 of the lift 1300 slide from the rear to the front along the slots 1301.

When the first and

second pins

1401 and 1402 slide from the rear to the front along the slots 1301, the sliding member 1700 and the outer handle 1800 into which the first and

second pins

1401 and 1402 are inserted slide to the front of the housing 1100 and the panel 10.

The protruding portion 1720 of the sliding member 1700 is withdrawn to the outside of the panel 10 through the protruding portion through-hole 1101. The outer handle 1800 is also withdrawn to the outside of the panel 10.

When the protruding portion 1720 of the sliding member 1700 is withdrawn, the catching portion 1710 is caught at the panel 10 and the housing 1100.

When the outer handle 1800 is withdrawn, a space in which a user may put his or her hand is formed between the outer handle 1800 and the panel 10 so that the user may hold the outer handle 1800. That is, when the outer handle 1800 is withdrawn, the outer handle 1800 is spaced apart from an outer side surface of the panel 10.

When the lift 1300 moves leftward, as illustrated in FIG. 21B, the cable 33 of the door latch connecting portion 30 is pulled due to the door latch connecting portion catching groove 1305 of the lift 1300. When the cable 33 is pulled, the stopper 34 of the door latch connecting portion 30 slides leftward from the state illustrated in FIGS. 32 and 33.

When the outer handle 1800 is withdrawn to a withdrawal complete position, the safety plate detection protrusion 2402 of the safety plate 2400 at which the stopper 34 of the door latch connecting portion 30 is installed is detected by the first sensor 2907. When the first sensor 2907 is pressed, power is applied to the motor 2610 of the latch portion 2000 due to a signal of the first sensor 2907.

Also, when the outer handle 1800 is withdrawn to the withdrawal complete position, the locking fitting portion 2403 of the safety plate 2400 at which the stopper 34 of the door latch connecting portion 30 is installed completely falls off from the locking member 2615 such that rotation of the locking member 2615 becomes possible.

Meanwhile, when the outer handle 1800 is withdrawn to the withdrawal complete position, the lift 1300 presses the third sensor 23b. When the lift 1300 is detected by the third sensor 23b, a detection signal is transmitted to the control portion, and the control portion stops operation of the driving portion 1900.

<Outer handle insertion process>

Hereinafter, a process in which the outer handle 1800 is inserted will be described.

FIG. 20 illustrates a state in which the outer handle 1800 is inserted.

When an instruction to insert the outer handle 1800 is input through a key, a remote controller, a switch, a vehicle speed value, or the like, the control portion operates the driving portion 1900.

When the motor 1910 rotates in a direction opposite from that when the outer handle 1800 is withdrawn, the lift 1300 moves rightward.

When the lift 1300 moves rightward, the first and

second pins

1401 and 1402 disposed in the slots 1301 of the lift 1300 slide from the front to the rear along the slots 1301.

When the first and

second pins

1401 and 1402 slide from the front to the rear along the slots 1301, the sliding member 1700 and the outer handle 1800 into which the first and

second pins

1401 and 1402 are inserted slide to the rear of the housing 1100 and the panel 10.

The protruding portion 1720 of the sliding member 1700 is inserted into the panel 10 through the protruding portion through-hole 1101. The outer handle 1800 also does not protrude to the outside of the panel 10.

When the lift 1300 moves rightward, the cable 33 of the door latch connecting portion 30 which has been pulled due to the door latch connecting portion catching groove 1305 of the lift 1300 as illustrated in FIG. 21B returns to its default state illustrated in FIG. 21A. When the cable 33 returns to its default state, the stopper 34 of the door latch connecting portion 30 slides rightward such that the state illustrated in FIGS. 32 and 33 is reached.

When the outer handle 1800 is inserted to an insertion complete position, the safety plate detection protrusion 2402 of the safety plate 2400 at which the stopper 34 of the door latch connecting portion 30 is installed deviates from the first sensor 2907. When the first sensor 2907 is not pressed, the control portion disconnects power from the motor 2610 of the latch portion 2000.

Thus, it is possible to prevent an electrical malfunction of the latch portion 2000 when the outer handle 1800 is inserted.

Also, when the outer handle 1800 is inserted to the insertion complete position, the locking fitting portion 2403 of the safety plate 2400 at which the stopper 34 of the door latch connecting portion 30 is installed is completely inserted into the safety plate fitting groove 2616 of the locking member 2615 such that rotation of the locking member 2615 becomes impossible.

Meanwhile, when the outer handle 1800 is inserted into the insertion complete position, the lift 1300 presses the third sensor 23a. When the lift 1300 is detected by the third sensor 23a, a detection signal is transmitted to the control portion, and the control portion stops operation of the driving portion 1900.

<Closing of door using cinching module>

When the user closes the panel 10 which is in an open state, the striker installed in the vehicle body presses the latch 2200 such that the latch 2200 rotates clockwise.

The latch 2200 rotates clockwise and then presses the fourth sensor 2901, and the locking portion 2371 of the pivoting member 2370 is inserted into the auxiliary locking groove 2202 of the latch 2200. In this state, when the user stops the operation of closing the panel 10, the panel 10 is incompletely closed. When the user completely closes the panel 10, the latch 2200 is further rotated clockwise and presses the fifth sensor 2902. When a signal is not received from the fifth sensor 2902 within a predetermined amount of time after a signal is received from the fourth sensor 2901, the control portion operates the motor of the actuator 2510 so that the cinching connecting portion 2520 is pulled toward the actuator 2510. As the cinching connecting portion 2520 is pulled, the lever 2530 coupled to the cinching connecting portion 2520 is rotated clockwise. When the lever 2530 is rotated, the latch 2200 is rotated clockwise due to the latch catching portion 2532 of the lever 2530.

In this case, although the height of the catching member 2521 of the cinching connecting portion 2520 varies in accordance with rotation of the lever 2530, since a bendable cable is provided as the cinching connecting portion 2520, the height variation may not affect the rotation of the lever 2530.

The outer circumferential surface (between the auxiliary locking groove 2202 and the locking groove 2201) of the latch 2200 pushes the locking portion 2371 of the pivoting member 2370. Therefore, the pivoting member 2370 is rotated counterclockwise.

When the panel 10 is completely closed, the locking portion 2371 rotates clockwise due to the pivoting member spring 2390 and is inserted into the locking groove 2201, and the latch 2200 is detected by the fifth sensor 2902. The control portion receives a signal from the fifth sensor 2902, stops operation of the actuator 2510, and rotates the actuator 2510 in a reverse direction. The control portion operates the actuator 2510 until the lever 2530 reaches an initial position of the lever 2530 as illustrated in FIG. 41 according to a predetermined stroke inside the actuator 2510. Different from the above description, a sensor capable of detecting the latch catching portion protrusion 2533 of the lever 2530 may be further provided, and the control portion may control operation of the actuator 2510 by detecting the position of the lever 2530.

Therefore, the lever 2530 is restored to its default position.

<Opening of door using outer handle>

When the user pulls the outer handle 1800 while the outer handle 1800 is withdrawn, the first support member 1410 slides forward. When the first support member 1410 slides forward, the second sensor detecting portion 1413, which is formed at the rear of the first support member 1410, presses the second sensor 22. When the second sensor 22 is pressed, the control portion receives a signal and operates the motor 2610 of the latch portion 2000.

When the motor 2610 is operated, the worm 2613 rotates. As the worm 2613 rotates, the worm gear 2614 rotates. As the worm gear 2614 rotates, the locking member 2615 rotates clockwise.

When the locking member 2615 rotates clockwise, the second step 2720 rotates counterclockwise, and the first step 2710, which is caught at the first detecting portion insertion groove 2721 of the second step 2720, also rotates counterclockwise. When the first step 2710 rotates counterclockwise, the pivoting member 2370, which is caught at the pivoting member catching portion 2711 of the first step 2710 rotates counterclockwise such that locking of the latch 2200 is released. When locking of the latch 2200 is released, the latch 2200 rotates counterclockwise due to an elastic force of the first restoring spring 2250 such that the panel 10 is opened.

Then, in order to restore the pivoting member 2370 to its default state, the motor 2610 rotates in a reverse direction. When the motor 2610 rotates in the reverse direction, the second step 2720 and the first step 2710 rotate clockwise, and the pivoting member 2370 also rotates clockwise due to an elastic force of the pivoting member spring 2390. When the detecting portion 2712 of the first step 2710 is detected by the sixth sensor 2903, and pressing of the fourth and

fifth sensors

2901 and 2902 are released, the control portion stops the rotation of the motor 2610.

<Opening of door using door lever connecting portion>

When the user pulls the door lever connecting portion 40 while the panel 10 is closed, the open plate 2300 connected to the door lever connecting portion 40 slides leftward. When the open plate 2300 slides leftward, the third step 2730 rotates counterclockwise, and the first step 2710, which is caught at the second detecting portion insertion groove 2731 of the third step 2730, also rotates counterclockwise.

A left-right length of the main gear catching portion 7532 is formed so that, when the main gear 7630 rotates due to the motor 7610, interference between the main gear catching portion 7532 and the cinching catching portion 7638 does not occur. Also, an up-down length of the main gear catching portion 7532 is formed so that, when the main gear 7630 rotates clockwise due to the lever 7530, the cinching catching portion 7638 does not push the main gear catching portion 7532 downward.

<Outer handle withdrawal process>

Hereinafter, a process in which the outer handle 3800 is withdrawn will be described.

When an instruction to withdraw the outer handle 3800 is input through a key, a remote controller, a switch, or the like, the control portion operates the driving portion 3900.

When the motor 3910 is operated, the first worm 3921 rotates. As the first worm 3921 rotates, the worm wheel 3922 of the first double gear rotates. The second worm 3923 also rotates together with the worm wheel 3922.

When the second worm 3923 rotates, the large gear 3924 of the second double gear rotates, and the small gear 3925 also rotates together with the large gear 3924.

When the small gear 3925 rotates, the first main gear 3926 rotates. When the first main gear 3926 rotates, the second main gear 3927 rotates, and the first rack 3928 is lifted upward. When the second main gear 3927 rotates, the second rack 3929 is lifted upward.

When the first and

second racks

3928 and 3929 are lifted upward, the lift 3300 connected to the first and

second racks

3928 and 3929 also slide upward.

When the lift 3300 slides upward, the protrusions 3730 of the sliding member 3700 that are disposed in the slots 3301 of the lift 3300 slide from the rear to the front along the slots 3301.

When the protrusions 3730 slide from the rear to the front along the slots 3301, the sliding member 3700 and the outer handle 3800 which are connected to the protrusions 3730 slide to the front of the housing 3100 and the panel 10.

The protruding portion 3720 of the sliding member 3700 is withdrawn to the outside of the panel 10 through the protruding portion through-hole 3101. The outer handle 3800 is also withdrawn to the outside of the panel 10.

When the protruding portion 3720 of the sliding member 3700 is withdrawn, the catching portion 3710 is caught at the housing 3100.

When the outer handle 3800 is withdrawn, a space in which a user may put his or her hand is formed between the outer handle 3800 and the panel 10 so that the user may hold the outer handle 3800. That is, when the outer handle 3800 is withdrawn, the outer handle 3800 is spaced apart from an outer side surface of the panel 10.

When the lift 3300 slides upward, as illustrated in FIG. 58B, the cable 33 of the door latch connecting portion 30 is pulled due to the door latch connecting portion catching groove 3304 of the lift 3300. When the cable 33 is pulled, the stopper 34 of the door latch connecting portion 30 slides rearward from the state illustrated in FIG. 63.

When the outer handle 3800 is withdrawn to a withdrawal complete position, the stopper cover 37 of the door latch connecting portion 30 is detected by a first sensor 7907. When the first sensor 7907 is pressed, power is applied to the motor 7610 of the latch portion 7000 due to a signal of the first sensor 7907.

Also, when the outer handle 3800 is withdrawn to the withdrawal complete position, the stopper cover 37 of the door latch connecting portion 30 completely deviates from the radius of rotation of the main gear 7630 such that rotation of the main gear 7630 becomes possible.

Meanwhile, when the outer handle 3800 is withdrawn to the withdrawal complete position, the lift 3300 presses the third sensor 23b. When the lift 3300 is detected by the third sensor 23b, a detection signal is transmitted to the control portion, and the control portion stops operation of the driving portion 3900.

<Outer handle insertion process>

Hereinafter, a process in which the outer handle 3800 is inserted will be described.

When an instruction to insert the outer handle 3800 is input through a key, a remote controller, a switch, a vehicle speed value, or the like, the control portion operates the driving portion 3900.

When the motor 3910 rotates in a direction opposite from that when the outer handle 3800 is withdrawn, the lift 3300 slides downward.

When the lift 3300 slides downward, the protrusions 3730 of the sliding member 3700 that are disposed in the slots 3301 of the lift 3300 slide from the front to the rear along the slots 3301.

When the protrusions 3730 slide from the front to the rear along the slots 3301, the sliding member 3700, which is connected to the protrusions 3730, and a sliding portion of the outer handle 3800 slide to the rear of the housing 3100 and the panel 10.

The protruding portion 3720 of the sliding member 3700 is inserted into the panel 10 through the protruding portion through-hole 3101. The outer handle 3800 also does not protrude to the outside of the panel 10.

When the lift 3300 slides downward, the cable 33 of the door latch connecting portion 30 which has been pulled due to the door latch connecting portion catching groove 3304 of the lift 3300 as illustrated in FIG. 58B returns to its default state illustrated in FIG. 58A. When the cable 33 returns to its default state, the stopper 34 of the door latch connecting portion 30 slides forward such that the state illustrated in FIG. 63 is reached.

When the outer handle 3800 is inserted to an insertion complete position, the stopper cover 37 of the door latch connecting portion 30 deviates from the first sensor 7907. When the first sensor 7907 is not pressed, power is disconnected from the motor 7610 of the latch portion 7000 due to a signal of the first sensor 7907.

Thus, it is possible to prevent an electrical malfunction of the latch portion 7000 when the outer handle 3800 is inserted.

Also, when the outer handle 3800 is inserted to the insertion complete position, the stopper cover 37 of the door latch connecting portion 30 is inserted within the radius of rotation of the installed main gear 7630 such that rotation of the main gear 7630 becomes impossible in the direction in which the panel 10 is opened.

Meanwhile, when the outer handle 3800 is inserted into the insertion complete position, the lift 3300 presses the third sensor 23a. When the lift 3300 is detected by the third sensor 23a, a detection signal is transmitted to the control portion, and the control portion stops operation of the driving portion 3900.

<Closing of door using cinching module>

When the user closes the panel 10 which is in an open state, the striker installed in the vehicle body presses the latch 7200 such that the latch 7200 rotates clockwise.

The latch 7200 rotates clockwise and then presses a fourth sensor 7901. In this state, when the user stops the operation of closing the panel 10, the panel 10 is incompletely closed. When the user completely closes the panel 10, the latch 7200 is further rotated clockwise and presses a fifth sensor 7902. When a signal is not received from the fifth sensor 7902 within a predetermined amount of time after a signal is received from the fourth sensor 7901, the control portion operates the motor of the actuator 7510 so that the cinching connecting portion 7520 is pulled toward the actuator 7510. As the cinching connecting portion 7520 is pulled, the lever 7530 coupled to the cinching connecting portion 7520 slides to the left side of the first housing 7110. When the lever 7530 slides, the main gear 7630 rotates clockwise as the cinching catching portion 7638 of the main gear 7630 that is inserted into the main gear catching portion 7532 moves leftward. When the main gear 7630 rotates clockwise, the catching portion 7631 rotates the latch 7200 clockwise.

When the panel 10 is completely closed, the first main gear detecting portion 7632 is detected by the sixth sensor 7903. Also, the fifth sensor 7902 is pressed by the latch 7200. The control portion receives signals from the fifth and

sixth sensors

7902 and 7903, stops operation of the actuator 7510, and rotates the motor (not illustrated) of the actuator 7510 in a reverse direction. Accordingly, the actuator 7510 slides the lever 7530 rightward, and the cinching catching portion 7538, which is caught at the main gear catching portion 7532 of the lever 7530, rotates counterclockwise such that the main gear 7630 is rotated in the reverse direction. The control portion rotates the main gear 7630 in the reverse direction until the second main gear detecting portion 7633 is detected by the sixth sensor 7903. When the second main gear detecting portion 7633 presses the sixth sensor 7903, the control portion stops operation of the motor 7610.

Therefore, the main gear 7630 and the lever 7530 are restored to their default positions.

<Opening of door using outer handle>

When the user pulls the outer handle 3800 while the outer handle 3800 is withdrawn, the first support member 3410 slides forward. When the first support member 3410 slides forward, the first support member 3410 does not press the second sensor 22 disposed at the rear of the first support member 3410. When the second sensor 22 is not pressed, the control portion receives a signal and operates the motor 7610 of the latch portion 7000.

When the motor 7610 is operated, the main gear 7630 rotates. As the main gear 7630 rotates, the main opening member 7300 slides rightward, and the pivoting member 7370 rotates counterclockwise due to the main opening member 7300 such that locking of the latch 7200 is released. The motor 7610 is operated until the main opening member 7300 is detected by the seventh sensor 7905. When locking of the latch 7200 is released, the latch 7200 rotates counterclockwise due to an elastic force of a spring installed at the latch 7200 such that the panel 10 is opened.

Then, in order to restore the main opening member 7300 and the main gear 7630 to their default states, the motor 7610 rotates in a reverse direction. When the motor 7610 rotates in the reverse direction, the main gear 7630 also rotates in the reverse direction and returns to its default position, and the pivoting member 7370 and the main opening member 7300 also return to their default positions due to an elastic force of a spring installed at each of the pivoting member 7370 and the main opening member 7300. When the second main gear detecting portion 7633 of the main gear 7630 is detected by the sixth sensor 7903, and the fourth and

fifth sensors

7901 and 7902 are not pressed, the control portion stops the rotation of the motor 7610.

<Opening of door using door lever connecting portion>

When, in case of emergency, the user manually pulls the door lever connecting portion 40 while the panel 10 is closed, the main opening member 7300 connected to the door lever connecting portion 40 slides rightward. When the main opening member 7300 slides rightward, the pivoting member 7370 rotates counterclockwise such that locking of the latch 7200 is released. When locking of the latch 7200 is released, the latch 7200 rotates counterclockwise due to an elastic force of a spring installed at the latch 7200 such that the panel 10 is opened.

<Outer handle withdrawal process>

Since the process in which the outer handle 3800 is withdrawn according to the third embodiment is the same as that according to the second embodiment except for a process related to the door latch connecting portion 30, detailed description thereof will be omitted.

When the lift 3300 slides upward, as illustrated in FIG. 58B, the cable 33 of the door latch connecting portion 30 is pulled due to the door latch connecting portion catching groove 3304 of the lift 3300. When the cable 33 is pulled, the safety plate 8400 at which the stopper 34 of the door latch connecting portion 30 is installed slides rightward from the state illustrated in FIG. 66.

When the outer handle 3800 is withdrawn to a withdrawal complete position, the safety plate detection protrusion 8402 of the safety plate 8400 at which the stopper cover 37 of the door latch connecting portion 30 is installed is detected by the first sensor 8907. When the first sensor 8907 is pressed, power is applied to the motor 8610 of the latch portion 8000 due to the first sensor 8907.

Also, when the outer handle 3800 is withdrawn to the withdrawal complete position, the locking fitting portion 8403 of the safety plate 8400 at which the stopper cover 37 of the door latch connecting portion 30 is installed completely deviates from the safety plate fitting groove 8616 of the locking member 8615 such that rotation of the locking member 8615 becomes possible.

<Outer handle insertion process>

Since the process in which the outer handle 3800 is inserted according to the third embodiment is the same as that according to the second embodiment except for a process related to the door latch connecting portion 30, detailed description thereof will be omitted.

When the lift 3300 slides downward, the cable 33 of the door latch connecting portion 30 which has been pulled due to the door latch connecting portion catching groove 3304 of the lift 3300 as illustrated in FIG. 58B returns to its default state illustrated in FIG. 58A. When the cable 33 returns to its default state, the safety plate 8400 at which the stopper 34 of the door latch connecting portion 30 is installed slides leftward such that the state illustrated in FIG. 66 is reached.

When the outer handle 3800 is inserted to an insertion complete position, the safety plate detection protrusion 8402 of the safety plate 8400 at which the stopper cover 37 of the door latch connecting portion 30 is installed is not detected by the first sensor 8907. When the first sensor 8907 is not pressed, power is disconnected from the motor 8610 of the latch portion 8000 due to a signal of the first sensor 8907.

Thus, it is possible to prevent an electrical malfunction of the latch portion 8000 when the outer handle 3800 is inserted.

Also, when the outer handle 3800 is inserted to the insertion complete position, the stopper cover 37 of the door latch connecting portion 30 is inserted into the safety plate fitting groove 8616 of the locking member 8615 of the safety plate 8400 at which the stopper cover 37 of the door latch connecting portion 30 is installed. Thus, rotation of the locking member 8615 becomes impossible.

<Closing of door using cinching module>

When the user closes the panel 10 which is in an open state, the striker installed in the vehicle body presses the latch 8200 such that the latch 8200 rotates clockwise.

The latch 8200 rotates clockwise and then presses a fourth sensor 8901. In this state, when the user stops the operation of closing the panel 10, the panel 10 is incompletely closed. When the user completely closes the panel 10, the latch 8200 is further rotated clockwise and presses a fifth sensor 8902. When a signal is not received from the fifth sensor 8902 within a predetermined amount of time after a signal is received from the fourth sensor 8901, the control portion operates the motor of the actuator 8510 so that the cinching connecting portion 8520 is pulled toward the actuator 8510. As the cinching connecting portion 8520 is pulled, the lever 8530 coupled to the cinching connecting portion 8520 is rotated clockwise. When the lever 8530 is rotated, the latch 8200 is rotated clockwise due to a latch catching portion 8532 of the lever 8530.

In this case, although the height of a catching member 8521 of the cinching connecting portion 8520 varies in accordance with rotation of the lever 8530, since a bendable cable is provided as the cinching connecting portion 8520, the height variation may not affect the rotation of the lever 8530.

When the panel 10 is completely closed, a latch catching portion protrusion 8533 is detected by a sixth sensor 8903. Also, the fifth sensor 8902 is pressed by the latch 8200. The control portion receives signals from the fifth and

sixth sensors

8902 and 8903, stops operation of the actuator 8510, and rotates the actuator 8510 in a reverse direction. The control portion is operated until a catching member fitting portion 8531 of the lever 8530 is caught at a right side end of the lever groove of the third housing 8150 according to a predetermined stroke inside actuator 8510.

Therefore, the lever 8530 is restored to its default position.

<Opening of door using outer handle>

When the user pulls the outer handle 3800 while the outer handle 3800 is withdrawn, the first support member 3410 slides forward. When the first support member 3410 slides forward, the first support member 3410 does not press the second sensor 22 disposed at the rear of the first support member 3410. When the second sensor 22 is not pressed, the control portion receives a signal and operates the motor 8610 of the latch portion 8000.

When the motor 8610 is operated, the locking member 8615 rotates clockwise. When the locking member 8615 rotates clockwise, the open plate 8700 rotates counterclockwise. When the open plate 8700 rotates, the pivoting member 8370, which is coupled to the open plate 8700, rotates counterclockwise such that locking of the latch 8200 is released. The motor 8610 is operated until the open plate 8700 is detected by the seventh sensor 8905. When locking of the latch 8200 is released, the latch 8200 rotates counterclockwise due to an elastic force of a spring installed at the latch 8200 such that the panel 10 is opened.

Then, the motor 8610 rotates in a reverse direction until the locking member 8615 is restored to its default state. Different from the above description, the locking member 8615 may return to its default position due to elasticity of a spring. When the locking member 8615 returns to its default position, the pivoting member 8370 and the open plate 8700 return to their default positions due to an elastic force of a spring installed at the pivoting member.

<Opening of door using door lever connecting portion>

When, in case of emergency, the user manually pulls the door lever connecting portion 40 while the panel 10 is closed, the main opening member 8300 connected to the door lever connecting portion 40 slides rightward. When the main opening member 8300 slides rightward, the open plate 8700 rotates counterclockwise. When the open plate 8700 rotates, the pivoting member 8370 coupled to the open plate 8700 rotates counterclockwise such that locking of the latch 8200 is released. When locking of the latch 8200 is released, the latch 8200 rotates counterclockwise due to an elastic force of a spring installed at the latch 8200 such that the panel 10 is opened.

The present invention has been described above with reference to the exemplary embodiments thereof, but those of ordinary skill in the art may modify or change the present invention in various ways within the scope not departing from the idea and range of the present invention described in the claims below.
