The self-priming door lock (commonly called rear lock) of the electric door is mainly applied to MPV automobile sliding door locks, and can be applied to all automobile side door locks at the same time, and besides the traditional door lock function, a front lock and a ground lock are required to be dragged. It should be noted that the modules included in the electric power-on/off integrated structure of the self-priming door lock, the central control and secondary opening structure of the self-priming door lock, the opening priority structure of the self-priming door lock, and the like may be crossed with each other, which is not limited to the above structures.

As shown in fig. 1 to 14, the integrated self-priming lock for the electric door of the automobile comprises: the hollow shell 10 is provided with a motor driving module 20, a transmission module 30, a clutch module 40, a central control module 50 and a locking module 60 which are all arranged in the shell 10.

Specifically, the housing 10 includes a first cavity 101 and a second cavity 102. The motor driving module 20, the transmission module 30, the clutch module 40 and the central control module 50 are all accommodated in the first cavity 101, and the locking module 60 is accommodated in the second cavity 102. Wherein, in order to avoid interference with the glass lifter, each module in the first cavity 101 is assembled in the door lock, and the shell structures related to the first cavity 101 and the second cavity 102 are in L-shaped layout (the included angle is 90 ° -120 °).

Further, the second cavity 102 includes an upper case 11, a lower case 12, and a middle partition (not shown) disposed between the upper case 11 and the lower case 12. A plurality of pull wire rubber cap sleeves 13 and wet and dry area passages (not shown in the figure) are also arranged in the shell 10. Each pull wire rubber cap sleeve 13 is used for being matched with the corresponding pull wire in a waterproof sealing way. The wet dry area aisle is closely coupled to the bulkhead for the harness to be connected on the dry area side by connectors 14.

The invention relates to a waterproof related structure which mainly comprises a middle partition board, a stay wire rubber cap sleeve 13 and a dry-wet partition board, wherein the dry-wet partition board can divide a wet dry area passageway into a dry area and a wet area. Specifically, the waterproof of each inhaul cable of the door lock end adopts a middle plate positioning, upper shell 11 and lower shell 12 sealing design; the waterproof of the stay wire adopts the design of a die-casting waterproof wall and a stay wire rubber cap sleeve 13; the harness is waterproof, a wet area-to-dry area passageway is established on the dry and wet partition board side of the side elevation, the passageway is closely connected with the dry and wet partition board, and the harness is connected on the dry area side through the connector 14. By combining the waterproof design, water spray level waterproof can be effectively realized.

In an embodiment of the present invention, as shown in connection with fig. 4 and 5, the transmission module 30 includes: the circle center rotates the sector toothed plate 31 connected to the inner wall of the shell 10, the first electric opening arms 32 and the self-priming arms 33 respectively arranged on two sides of the sector toothed plate 31, the second electric opening arms 34 rotatably connected to the inner wall of the shell 10 and the opening arms 35 rotatably connected to the inner wall of the shell 10.

Specifically, the first electric opening arm 32 includes a first arm 321 and a second arm 322 disposed at an included angle, and the included angle may be an obtuse angle. The connection between the first arm 321 and the second arm 322 is connected to the sector toothed plate 31 through the first rotating shaft 323, so that the first electric opening arm 32 can rotate around the first rotating shaft 323.

The first arm 321 is provided with a first stop 324, and the preset position of the sector toothed plate 31 is provided with a second stop 311. The first rotating shaft 323 is sleeved with a driving torsion spring 325, two ends of the driving torsion spring 325 are respectively abutted against the first stop block 324 and the second stop block 311, so that the second support arm 322 maintains a state of being abutted against the second stop block 311, namely, when the first electric opening arm 32 is in an initial state (also called an intermediate state) and an electric suction state, the first electric opening arm 32 is gathered in the area where the sector toothed plate 31 is located as much as possible, the space occupied by the first electric opening arm 32 is reduced, and the compactness of design is ensured.

Further, an end portion of the first arm 321 far from the first rotating shaft 323 is recessed inwards to form an arc surface. The second electric opening arm 34 includes a third arm 341 and a fourth arm 342 disposed at an included angle, and a connection portion between the third arm 341 and the fourth arm 342 is connected to the inner wall of the housing 10 through a second rotating shaft 343, where the third arm 341 and the fourth arm 342 are respectively located at two opposite sides of the second rotating shaft 343 and are disposed in a substantially straight line. Referring to fig. 7, an end of the third arm 341 away from the second rotating shaft 343 is provided with an electric arm guide pulley 344, and the electric arm guide pulley 344 can rotate around its own rotating shaft. The first arm 321 is matched with the electric arm guide wheel 344 through its own cambered surface, so as to drive the third arm 341 to rotate around the second rotating shaft 343, and further make the fourth arm 342 press the opening arm 35. As shown in fig. 5, the first electric opening arm 32 and the second electric opening arm 34 are both in a rotating motion, so that the first support arm 321 can ensure a press fit relationship with the third support arm 341 during rotation through the rotation fit of the cambered surface of the first support arm 321 and the electric arm guide wheel 344 of the third support arm 341.

It can be understood that the predetermined position of the opening arm 35 extends vertically to form a limiting block 351, and the fourth arm 342 is abutted to the limiting block 351 under the driving of the third arm 341 and can drive the opening arm 35 to rotate.

Referring to fig. 4, the middle portion of the self-priming arm 33 is rotatably connected to the sector plate 31 through a self-priming shaft 331. The self-priming arm 33 includes a first self-priming arm 332 and a second self-priming arm 333 disposed on opposite sides of the self-priming shaft 331, where the first self-priming arm 332 and the second self-priming arm 333 are disposed substantially in a straight line. The motor driving module 20 is used for driving the sector toothed plate 31 to rotate along a preset direction so as to drive the self-priming arm 33 to rotate, thereby switching the locking module 60 to a locking state.

As shown in fig. 4, 5 and 14, the lock module 60 includes: a catch plate 61 and a locking claw 62. The pawl 62 is rotatably attached to the inner wall of the housing 10. The locking groove 611 is formed on one side, close to the locking claw 62, of the clamping plate 61, and is used for being matched with a preset fixing part of the vehicle door, when the vehicle door is closed, and the preset fixing part extends into the locking groove 611, and the opening of the locking groove 611 is closed by the locking claw 62, the locking module 60 is in a locking state, at the moment, the vehicle door can not be opened, and the locking claw 62 can limit the rotation of the clamping plate 61, so that the clamping plate 61 maintains the matched state with the preset fixing part; when the catch plate 61 rotates to disengage the predetermined fixing member from the locking groove 611, the locking module 60 is in an unlocked state, and the door can be opened.

Further, the predetermined position of the card 61 extends outwardly to form a drive arm 612. The self-priming arm 33 is used for driving the clamping plate 61 to rotate by poking the driving arm 612, that is, when the self-priming arm 33 presses the driving arm 612, the locking groove 611 is matched with a preset fixing component, so that the vehicle door is locked. Specifically, the second self-priming arm 333 drives the driving arm 612 to rotate the clamping plate 61.

Wherein the locking module 60 further comprises a main release arm 63. The middle part of the main release arm 63 and the locking pawl 62 are coaxially and rotatably connected to the inner wall of the housing 10 via a release shaft 631, and the side remote from the opening arm 35 is fixedly connected to the locking pawl 62, so that the locking pawl 62 can rotate synchronously with the main release arm 63. The opening arm 35 drives the locking claw 62 to unlock the catch plate 61 by pulling the main release arm 63. That is, when the opening arm 35 pulls the main release arm 63, the locking claw 62 is driven to rotate, so that the locking claw 62 is separated from the limiting action on the catch plate 61, and at this time, the rotation of the catch plate 61 is not affected any more, so that the vehicle door can be opened manually or electrically.

Further, a side edge of the main release arm 63 adjacent to the opening arm 35 extends vertically to form a first flange 632, and a side edge of the opening arm 35 adjacent to the main release arm 63 extends vertically to form a second flange 352. When the opening arm 35 abuts against the main release arm 63, the second flange 352 abuts against the first flange 632. The outer surfaces of the first flange 632 and the second flange 352 are all in cambered surface arrangement, when the opening arm 35 dials the main release arm 63, the main release arm 63 is in rotary motion, so that the cambered surfaces of the first flange 632 and the second flange 352 can adapt to the rotary motion, and the opening arm 35 is ensured to dial the main release arm 63 normally.

Wherein the edge preset position of the main release arm 63 extends outwards to form a fixing arm 633. A reset torsion spring 634 is sleeved on the release shaft 631; one end of the reset torsion spring 634 abuts against the fixed arm 633, and the other end is fixed in the housing 10 (including the fixed seat 15 fixed in the housing 10), so that the main release arm 63 drives the locking pawl 62 to maintain the locking state of the clamping plate 61. That is, when the self-priming arm 33 moves the driving arm 612 to lock the catch plate 61 and the locking pawl 62, the self-priming arm 33 is reset, and then the locking pawl 62 is maintained in a state of locking the catch plate 61 by the elastic force of the reset torsion spring 634. It should be noted that, one end of the reset torsion spring 634 shown in the drawings is suspended, but in actual assembly, the end abuts against the fixing arm 633, so the description herein will be based on the actual assembly.

Further, the lock module 60 also includes a secondary release arm 64. The middle part of the auxiliary release arm 64 is rotatably connected to the inner wall of the housing 10 coaxially with the locking pawl 62, and in this embodiment, the auxiliary release arm 64 is provided between the main release arm 63 and the locking pawl 62 via a release shaft 631. One end of the auxiliary release arm 64 is provided with a pulling rope (not shown) through the through hole, and the pulling rope is used for driving the locking claw 62 to unlock the clamping plate 61 when being pulled. The other end of the cable can be arranged at the manual door opening button of the vehicle door, when the cable is manually pulled, the auxiliary release arm 64 is driven to rotate, and the rotation direction is consistent with the rotation direction of the main release arm 63 which is poked by the opening arm 35, so that the stop pawl 62 breaks away from the limiting action on the clamping plate 61, and the situation that the vehicle door cannot be opened is avoided in emergency.

As shown in connection with fig. 14, the locking groove 611 includes a first side wall 6111 and a second side wall 6112. The first side wall 6111 is disposed on a side of the second side wall 6112 away from the driving arm 612, and a first clamping block 6113 is disposed on the top. The locking pawl 62 is provided with a second detent 621. The second clamping block 621 includes a blocking edge 6211 and an arc edge 6212, the blocking edge 6211 and the arc edge 6212 are disposed at an acute angle, and the arc edge 6212 is located at a side of the locking claw 62 near the driving arm 612. When the catch plate 61 is in the locking stroke, the first catch 6113 moves along the arcuate edge 6212 to force the pawl 62 to rotate outwardly in a direction away from the locking groove 611; when the catch plate 61 rotates to the maximum locking stroke or beyond the locking stroke, the first catch 6113 passes over the arcuate edge 6212. At this time, the second clamping block 621 of the locking claw 62 extends into the locking groove 611, and rotates in a direction approaching the locking groove 611 under the action of the return torsion spring 634, and maintains the second clamping block 621 with a tendency of extending into the locking groove 611, so that the first clamping block 6113 is clamped on the flange 6211, the rotation of the clamping plate 61 is limited, and the vehicle door is maintained in the locked state. When unlocking is required, the opening arm 35 drives the main release arm 63 to rotate or the auxiliary release arm 64 to be pulled, so as to drive the locking claw 62 to rotate along the direction away from the locking groove 611, and the second clamping block 621 is separated from the abutting state with the first clamping block 6113, and at this time, the rotation of the clamping plate 61 is not limited.

In summary, the implementation principle of the electric suction opening integrated structure of the self-suction door lock is as follows:

As shown in fig. 4, in the electric suction process, the motor driving module 20 drives the sector toothed plate 31 to rotate along the first direction (anticlockwise in fig. 4) so as to drive the self-suction arm 33 to rotate, and thus drive the clamping plate 61 to rotate, so that the locking claw 62 closes the locking groove 611 and locks the clamping plate 61; as shown in fig. 5, the electric opening process is used to drive the sector toothed plate 31 to rotate in a second direction (clockwise in fig. 5) so as to drive the first electric opening arm 32 to press in a direction approaching the second electric opening arm 34, so that the second electric opening arm 34 drives the locking claw 62 through the pressing opening arm 35 to unlock the clamping plate 61. When the electric suction operation is completed, the sector plate 31 is reset to the initial position. Therefore, the motor driving module 20 pushes the sector toothed plate 31 to rotate, and the power simultaneously meets the two functions of electric power on and electric power off, thereby meeting the design requirements of high efficiency, no noise and compact space.

Further, as shown in fig. 3, the motor driving module 20 includes a driving motor 21, a worm 22 coaxially provided on an output shaft of the driving motor 21, and a planetary reduction gear box 23 engaged with the worm 22. The gear meshed with the planetary reduction gearbox 23 is arranged on the arc edge of the sector toothed plate 31, and the driving motor 21 is used for driving the planetary reduction gearbox 23 to run through the worm 22, so that the sector toothed plate 31 is driven to rotate along the first direction or the second direction, and therefore, planetary power is adopted, electric opening and sucking actions are respectively output according to positive and negative rotation based on double-internal pushing layout, and space can be greatly saved.

Wherein the inner wall of the housing 10 is provided with an electric in-place switch (not shown) and an initial position switch (not shown). The sector toothed plate 31 is provided with a sensing element 312. When the sector toothed plate 31 rotates to a preset initial position, the sensing piece 312 is sensed by the initial position switch; when the sector toothed plate 31 rotates in the second direction to a preset electrical open position, the sensing element 312 is sensed by the electrical open-in-place switch. Wherein, the electric suction action can be correspondingly provided with an electric suction in-place switch.

In an embodiment of the present invention, as shown in connection with fig. 7-11, the clutch module 40 includes: the first safety arm 41 rotatably connected to the preset position of the inner wall of the housing 10, and the opening priority arm 43, the inner opening arm 44 and the outer opening arm 45 rotatably connected to the preset position of the inner wall of the housing 10 through the central control shaft 42. The inner opening arm 44 is connected with an inner handle (also called an inner handle, etc.) of the vehicle door through a corresponding cable structure, the outer opening arm 45 is connected with an outer handle (also called an outer handle, etc.) of the vehicle door through a corresponding cable structure, and through holes of the inner opening arm 44 and the outer opening arm 45 in the drawing are parts connected with respective cable structures.

The opening arm 35 is in a rotary fit with the central control shaft 42 and a second safety arm 47 is connected in rotation via a safety shaft 46 on the side remote from the opening priority arm 43. The inner opening arm 44 and the outer opening arm 45 can drive the opening priority arm 43 to rotate along the same direction, so as to drive the opening arm 35 to rotate, thereby unlocking the locking module 60.

Specifically, as shown in connection with fig. 12 to 13, the second safety arm 47 is provided with a safety torsion spring 471. The safety torsion spring 471 is sleeved on the safety shaft 46, one end of the safety torsion spring abuts against a preset position of the opening arm 35, and the other end of the safety torsion spring abuts against the second safety arm 47, so that the second safety arm 47 maintains a state of being matched with the opening priority arm 43, and the opening priority arm 43 can drive the opening arm 35 to rotate. When the second safety arm 47 abuts against the opening priority arm 43, the second safety arm includes both an abutment component along the vertical direction of the opening priority arm 43 and an abutment component along the parallel direction of the opening priority arm 43. At this time, as shown in fig. 12, if the opening priority arm 43 rotates along the direction approaching to the second safety arm 47, because the force action point has an acute angle with the two lines of travel of the central control shaft 42 and the safety shaft 46, the component of the second safety arm 47 and the abutment of the second safety arm 47 along the parallel direction will exert a pressure on the safety shaft 46 when the opening priority arm 43 rotates, and because the safety shaft 46 is disposed on the opening arm 35, the safety shaft 46 will rotate around the central control shaft 42 to further drive the opening arm 35 to rotate, so that the effect that the opening priority arm 43 can drive the opening arm 35 to rotate when the second safety arm 47 abuts against the opening priority arm 43 is achieved. It should be noted that, the second electric opening arm 34 drives the opening arm 35 to open the door electrically, and the second safety arm 47 drives the opening arm 35 to be affected by the actions of the inner opening arm 44 (pulling the inner handle to open the door) and the outer opening arm 45 (pulling the outer handle to open the door), and the two ways of driving the opening arm 35 are independent from each other, i.e. the opening arm 35 can open the door automatically by electric operation or manually by pulling the inner handle and the outer handle.

The central control module 50 is configured to drive the first safety arm 41 to rotate, thereby pressing the second safety arm 47, tilting one end of the second safety arm 47, and maintaining the second safety arm 47 in a state of being separated from the opening priority arm 43. When the user issues an instruction such as a car locking instruction to the central control module 50, the central control module 50 presses the second safety arm 47 through the first safety arm 41, so that the second safety arm 47 is decoupled from the opening priority arm 43, and at this time, the opening priority arm 43 is driven by the inner opening arm 44 or the outer opening arm 45 to rotate, so that the opening arm 35 cannot be driven to rotate, that is, at this time, neither the inner handle nor the outer handle is pulled to open the car door.

Specifically, the central control module 50 includes: a central control motor 51, a central control worm 52 coaxially arranged with an output shaft of the central control motor 51, and a central control worm wheel 53 meshed with the central control worm 52. The central control turbine 53 is provided with a first driving rod 54, and the first driving rod 54 is used for driving the first safety arm 41 to rotate in the forward direction or the reverse direction.

The first safety arm 41 includes a semicircular safety arm body 411 and a driving block 412 extending from an arc surface of the safety arm body 411 to the outside. The driving block 412 is used to control the second safety arm 47 to disengage from the opening priority arm 43. A first driving groove 413 into which the first driving rod 54 can extend is formed in the middle of the cambered surface of the safety arm main body 411; the number of the first driving rods 54 is three, and are equiangularly distributed from the center of the center control turbine 53. When the first driving rod 54 rotates in the first driving slot 413 in the forward and reverse directions, the driving block 412 is driven to rotate in the forward and reverse directions synchronously. When the first driving rod 54 drives the driving block 412 to press the second safety arm 47 away from the end of the opening priority arm 43, the end of the second safety arm 47 close to the opening priority arm 43 is tilted, so as to separate from the matching state with the opening priority arm 43.

Further, a press-in-place switch 55 is also provided in the housing 10. When the driving block 412 presses the second safety arm 47 to a predetermined stroke, the press-in-place switch 55 is triggered by the driving block 412, and at this time, the center control motor 51 stops operating, so that the first safety arm 41 is maintained in a state of pressing the second safety arm 47.

Further, in some embodiments, as shown in fig. 11, the outer opening arm 45 is integrally connected with the opening priority arm 43, and is surrounded by a limit half groove including two right-angle edges at one end near the self-priming arm 33, so that the self-priming arm 33 can only rotate unidirectionally around the self-priming shaft 331. That is, when the sector toothed plate 31 is in the electric suction stroke, the limit half groove can prevent the self-suction arm 33 from rotating reversely.

Specifically, the middle portion of the self-priming arm 33 is rotatably coupled to the sector plate 31 via a self-priming shaft 331. The self-priming arm 33 includes a first self-priming arm 332 and a second self-priming arm 333 disposed on opposite sides of the self-priming shaft 331. Thus, the second self-priming arm 333 can lock the lock module 60 by activating the limiting action of the priority arm 43 on the first self-priming arm 332. At the same time, the opening priority arm 43 can drive the first self-priming arm 332 to rotate, so that the second self-priming arm 333 is separated from the track of the locking module 60 in advance. That is, when the self-priming arm 33 is not in contact with the driving arm 612 during the electric suction process, the inner opening arm 44 or the outer opening arm 45 can be pulled, the first self-priming arm 332 is shifted in advance by the opening priority arm 43, so that the self-priming arm 33 rotates around the self-priming shaft 331, the self-priming arm 33 can be rotated in advance by a larger amount, and the second self-priming arm 333 is separated from the self-priming track, at this time, even if the sector toothed plate 31 continues to rotate, the self-priming arm 33 does not touch the driving arm 612, thereby stopping the electric suction operation.

Therefore, when the door is in the electric door closing state (electric suction), if the person is at risk of being clamped by the door at this time, the opening priority arm 43 can be driven to rotate by pulling the inner handle or the outer handle, so that the electric door closing operation of the door is terminated, the anti-clamping opening priority function is realized, and the safety during electric suction is ensured.

Further, a self-priming arm guide wheel 334 is provided on the side of the first self-priming arm 332 away from the self-priming shaft 331, so that the opening priority arm 43 can adapt to the rotation motion of the self-priming arm 33.

As shown in fig. 4, 5 and 11, the inner opening arm 44 includes a first inner opening arm 441 and a second inner opening arm 442. The first inner opening arm 441 is used for connecting a cable, and a user can pull the cable to rotate the inner opening arm 44. The second inner opening arm 442 is used for driving the opening priority arm 43 to rotate in a unidirectional manner. The opening priority arm 43 is provided with a limiting groove 431, and the second inner opening arm 442 abuts against the bottom of the limiting groove 431, so that when the inner opening arm 44 rotates along the direction close to the opening priority arm 43, the inner opening arm 44 can drive the opening priority arm 43 to rotate; when the inner opening arm 44 rotates in a direction away from the opening priority arm 43, the second inner opening arm 442 is separated from the contact with the opening priority arm 43, and the opening priority arm 43 cannot be driven to rotate.

Further, the inner opening arm 44 also includes a third inner opening arm 443. The second inner branch arm 442 and the third inner branch arm 443 are disposed on the left and right sides of the first inner branch arm 441, respectively. The side of the central control turbine 53 facing away from the first driving rod 54 is further provided with a secondary opening arm 56 and a second driving rod 57 which can rotate independently relative to the central control turbine 53. The secondary opening arm 56 is fixedly connected to the second driving rod 57 at a predetermined angle, which is here an acute angle. The safety arm body 411 is further provided with a fan-shaped secondary rotation plate 58 at one side thereof adjacent to the secondary opening arm 56. The arc surface of the secondary rotation plate 58 is provided with a second driving groove 581 into which the second driving rod 57 is inserted. The third inner opening arm 443 is used for driving the secondary opening arm 56 to rotate so as to drive the safety arm body 411 to rotate, and the rotation direction is opposite to the rotation direction of the first safety arm 41 pressing the second safety arm 47, so that the pressing of the second safety arm 47 is released.

Therefore, the invention realizes the secondary unlocking function, and when the door lock is in a locking state, the door lock can be unlocked only by pulling the inner handle twice. Pulling the inner handle for the first time, so that the inner opening arm 44 rotates for the first time, thereby releasing the pressing state of the first safety arm 41 to the second safety arm 47, and switching the second safety arm 47 to a state of abutting and matching with the opening priority arm 43, and realizing central control unlocking; the inner handle is pulled further to rotate the inner opening arm 44 a second time, so that the opening arm 35 is driven to rotate by driving the opening priority arm 43, and the locking module 60 is unlocked, so that the vehicle door can be opened. The door lock is opened by realizing the secondary execution of the opening function, the original central control button and the stay wire are canceled by the design, and the unlocking action of the traditional safety button is reduced.

Further, a central control wire arm 582 is further provided on the side of the secondary rotating plate 58 facing away from the safety arm main body 411, and a side of the central control wire arm 582 facing away from the secondary rotating plate 58 is used for connecting a cable. The central control arm 582 is used for driving the secondary rotating plate 58 to rotate, and has the same direction as the third inner opening arm 443 drives the secondary rotating plate 58 to rotate. That is, the central control unlocking can be realized by pulling the central control stay wire arm 582, a central control unlocking mode is added, the guarantee of internal unlocking is enhanced, and passengers are prevented from being locked in the vehicle.

Further, as shown in connection with fig. 11, the locking module 60 further includes a child lock arm 65 rotatably connected to the housing 10, and in this embodiment, the child lock arm 65 is disposed on the fixing base 15. The edge of the inner opening arm 44 adjacent to the side of the locking module 60 extends outwardly to form a locking arm 444. The child lock arm 65 is configured to abut against the stopper arm 444 when rotated to a predetermined angle, so as to rigidly limit the rotation of the inner opening arm 44, at this time, the inner opening arm 44 and thus the inner handle are prevented from being pulled, and the child cannot open the door lock from the inside of the vehicle, but does not affect the person outside the vehicle to drive the outer opening arm 45 to rotate by pulling the outer handle, so as to unlock the locking module 60, and thus open the door outside the vehicle. The scheme does not need to open holes on the vehicle body, has fewer parts and saves space.
