Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Referring to fig. 2-5, an embodiment of the invention discloses a mobile terminal, which includes a housing 100, a camera 200 and a driving mechanism 300.

The housing 100 is a supporting member of the mobile terminal, and provides a mounting base and protection for other members of the mobile terminal. The casing 100 has a frame 110 and an inner cavity 120, and the frame 110 has a through hole, which is communicated with the inner cavity 120.

The drive mechanism 300 is disposed in the interior cavity 120 of the housing 100. The camera 200 is movably disposed on the housing 100. The driving mechanism 300 is connected to the camera 200 and can drive the camera 200 to move. The camera 200 can pass through the through hole under the driving of the driving mechanism 300, so as to extend out of the mobile terminal, and of course, the camera 200 can also retract into the inner cavity 120 of the mobile terminal under the driving of the driving mechanism 300.

In this embodiment, the driving mechanism 300 includes a driving body 310, a base, a first movable base 330, a first supporting rod 340, and a first elastic expansion member 350.

The first elastic expansion member 350 has good elasticity and can expand and contract. The first elastic expansion member 350 is connected at both ends thereof to a base and a first movable base 330, respectively, which are disposed in the housing 100. Two ends of the first supporting rod 340 are respectively hinged with the first moving seat 330 and the camera 200, so that the first supporting rod 340 can rotate relatively to the first moving seat 330 and the camera 200.

The first movable seat 330 is movably disposed in the inner cavity 120 of the housing 100, and in particular, the first movable seat 330 may move in the inner cavity 120 in a sliding or rolling manner. The first elastic expansion member 350 applies a first elastic force to the first movable base 330. The driving body 310 is coupled to the first moving base 330 for applying a first traction force to the first moving base 330. In the first elastic force and the first traction force, one of the first elastic force and the first traction force is used for driving the first movable base 330 to move towards the direction close to the base, the other one of the first elastic force and the first traction force is used for driving the first movable base 330 to move towards the direction away from the base, and the first support rod 340 can drive the camera 200 to enter and exit the through hole along with the movement of the first movable base 330.

In one embodiment, as shown in fig. 3, the first elastic force drives the first movable base 330 to move toward the fixed base 320. Correspondingly, the first traction force drives the first movable seat 330 to move in a direction away from the fixed seat 320.

In one embodiment, the base seat may be a fixed seat 320, and the fixed seat 320 is fixed in the casing 100 and may serve as a base for the movement of the first movable seat 330. Of course, the base seat may be a movable seat body as long as the mechanical conditions described above are satisfied.

For convenience of understanding, the embodiment shown in fig. 3 is taken as an example to illustrate that the first traction force applied by the driving body 310 can make the first movable seat 330 away from the fixed seat 320 during the specific operation. During the movement of the first movable base 330 away from the fixed base 320, the first supporting rod 340 is pulled to tilt (as shown in fig. 4), and finally the first supporting rod 340 pulls the camera 200 to retract into the inner cavity 120 through the through hole. When the first traction force applied by the driving main body 310 is removed, the first elastic expansion piece 350 pulls the first movable seat 330 close to the fixed seat 320 under the elastic restoring force, and the first movable seat 330 supports the first supporting rod 340 in the moving process of gradually approaching the fixed seat 320, and finally the first supporting rod 340 pushes the camera 200 out of the mobile terminal through the through hole. It can be seen that the first supporting rod 340 can drive the camera 200 into and out of the through hole along with the movement of the first movable base 330.

Of course, the first elastic force may drive the first movable seat 330 to move away from the fixed seat 320. Correspondingly, the first traction force drives the first movable seat 330 to move in a direction approaching the fixed seat 320. In this case, the driving of the camera 200 by the first elastic force and the first traction force enables the camera 200 to enter and exit the through hole.

As can be seen from the above working process, the mobile terminal disclosed in the embodiment of the present invention can realize the operation of the mobile terminal through the position conversion of the camera 200 (from the inside of the housing 100 to the outside of the housing 100 and from the outside of the housing 100 to the inside of the housing 100) on the premise that the mobile terminal has the shooting function, and the layout of the camera 200 does not occupy the area on the mobile terminal where the display screen is disposed, and further increase of the screen occupation ratio of the mobile terminal is not limited. Therefore, the mobile terminal disclosed by the embodiment of the invention can solve the problem that the arrangement of the camera in the prior art can influence the development of the mobile terminal towards the large screen ratio direction.

On the basis that the base seat is the fixed seat 320, the mobile terminal disclosed in the embodiment of the present invention may further include a second movable seat 360, a second supporting rod 370, and a second elastic expansion member 380.

The second movable base 360 is movably disposed in the inner cavity 120, and the first movable base 330 and the second movable base 360 may be disposed on two sides of the fixed base 320, respectively. Specifically, the second movable base 360 may be movable in the inner cavity 120 in a sliding or rolling manner. The two ends of the second elastic expansion piece 380 are respectively connected with the fixed base 320 and the second movable base 360. The second support bar 370 is hinged at both ends to the second movable base 360 and the camera head 200, respectively. The driving body 310 is connected to the second moving seat 360 and applies a second traction force to the second moving seat 360, and the second elastic expansion member 380 is used to apply a second elastic force to the second moving seat 360. One of the second traction force and the second elastic force is used for driving the second movable seat 360 to move towards the direction away from the fixed seat 320, and the other one is used for driving the second movable seat 360 to move towards the direction close to the fixed seat 320.

In a specific embodiment, as shown in fig. 3, the second traction force is used to drive the second movable base 360 to move away from the fixed base 320, the second elastic force is used to drive the second movable base 360 to move towards the fixed base 320, and the second support rod 370 can drive the camera 200 to enter and exit the through hole along with the movement of the second movable base 360.

Still taking the embodiment shown in fig. 3 as an example, in a specific operation process, when the driving body 310 applies a second traction force to the second movable seat 360, the second movable seat 360 can be far away from the fixed seat 320, and during the movement of the second movable seat 360 away from the fixed seat 320, the second movable seat 360 pulls the second support rod 370, so that the second support rod 370 is tilted (as shown in fig. 4), and finally the second support rod 370 pulls the camera 200 to retract into the inner cavity 120 through the through hole. When the second traction force applied by the driving main body 310 is removed, the second elastic expansion piece 380 pulls the second movable base 360 to approach the fixed base 320 under the elastic restoring force, and the second movable base 360 supports the second support rod 370 during the moving process of gradually approaching the fixed base 320, and finally the second support rod 370 pushes the camera 200 out of the mobile terminal through the through hole.

Of course, the second traction force may be used to drive the second movable seat 360 to move towards the direction close to the fixed seat 320, and the second elastic force may be used to drive the second movable seat 360 to move towards the direction away from the fixed seat 320. In this case, the second supporting rod 370 can drive the camera 200 into and out of the through hole along with the movement of the second movable base 360.

In the above solution, the movement of the camera 200 is driven by the first support rod 340 and the second support rod 370 simultaneously, which undoubtedly enables the driving mechanism 300 to drive the camera 200 more stably.

In a further preferred embodiment, the first movable base 330 and the second movable base 360 may be symmetrically disposed on both sides of the fixed base 320. Similarly, the first support bar 340 and the second support bar 370 may also be symmetrically distributed on both sides of the fixing base 320. In this case, the driving of the camera 200 can be more balanced.

The first elastic expansion member 350 may be an elastic rubber band or a spring. Preferably, the first elastic expansion member 350 is a first expansion spring having good strength and elasticity, and capable of ensuring the stability of elastic expansion. Similarly, the second elastic expansion element 380 may be an elastic rubber band or a spring. Preferably, the second elastic expansion member 380 is a second expansion spring.

In order to ensure the stability of the movement of the first movable base 330, in a preferred embodiment, the mobile terminal disclosed in this embodiment may further include a first guide bar 390, the first guide bar 390 is fixedly connected to the fixed base 320, the first elastic expansion piece 350 may be sleeved on the first guide bar 390, and the first movable base 330 is slidably sleeved on the first guide bar 390. At this time, the expansion and contraction of the first elastic expansion part 350 and the movement of the first movable base 330 can be performed along the first guide bar 390, which undoubtedly enables the first elastic expansion part 350 to be more effectively expanded and contracted, and also enables the movement path of the first movable base 330 to be more accurate.

Similarly, in order to ensure the stability of the movement of the second movable base 360, in a preferred embodiment, the mobile terminal disclosed in this embodiment may further include a second guide rod 3100, and the second guide rod 3100 is fixedly connected to the fixed base 320. The second elastic expansion piece 380 is sleeved on the second guide rod 3100. The second movable base 360 is slidably fitted over the second guide rod 3100. In the process that the second elastic expansion piece 380 stretches and retracts and the second movable seat 360 moves, the stretching of the second elastic expansion piece 380 and the movement of the second movable seat 360 can be carried out along the second guide rod 3100, the stretching of the second elastic expansion piece 380 can be better achieved undoubtedly, and meanwhile the second movable seat 360 can be moved more accurately.

The first movable base 330 and the second movable base 360 can move more stably, and the moving accuracy of the camera 200 driven by the first supporting rod 340 and the second supporting rod 370 can be higher.

As described above, the base seat may be a movable seat body, please refer to fig. 6, fig. 6 is a partial structural schematic diagram of another mobile terminal according to the embodiment of the present invention, in the mobile terminal shown in fig. 6, the base seat may be a third movable seat 3110, two ends of the first elastic expansion piece 350' are respectively connected to the first movable seat 330 and the third movable seat 3110, and the third movable seat 3110 is movably disposed in the housing 100. The mobile terminal may further include a third support bar 3120, and both ends of the third support bar 3120 may be hinged with the third moving seat 3110 and the camera head 200, respectively. In this case, the driving body 310 can drive the first movable base 330 to move relative to the third movable base 3110 by the first traction force, but the effect is not good. Although the third moving seat 3110 can move, the third moving seat 3110 and the third support bar 3120 can be integrated to prevent the third moving seat 3110 from moving in the same direction under the influence of the first traction force.

In a specific implementation process, a designer may design a fitting size between the third support bar 3120 and the third movable seat 3110, so that when the first movable seat 330 is moved by the first traction force, the first elastic expansion piece 350' is elongated, and the retracting movement of the camera 200 may drive the third movable seat 3110 to move toward a direction opposite to the first movable seat 330. In this case, the first moving seat 330 and the third moving seat 3110 move in opposite directions, so that the first moving seat 330 and the third moving seat 3110 move away from each other. After the first traction force is removed, the first movable seat 330 and the third movable seat 3110 approach each other by the elastic force of the first elastic expansion member 350'.

Similarly, in order to improve the stability of the camera head 200 in terms of extension and retraction, in a preferred embodiment, the third support bar 3120 and the first support bar 340, and the third movable seat 3110 and the first movable seat 330 may be symmetrically distributed with the first elastic expansion piece 350' as a center of symmetry.

In the embodiment of the present invention, the driving body 310 can drive the first movable base 330 and the base to move relatively. There are various mechanisms capable of applying the traction force to the first movable base 330 and the base. In a specific embodiment, on the premise that the mobile terminal includes the first movable seat 330 and the second movable seat 360, the driving body 310 may include two telescopic members, and the two telescopic members may be respectively connected to the first movable seat 330 and the second movable seat 360, so as to respectively apply the first traction force and the second traction force to the first movable seat 330 and the second movable seat 360 through self-extension. Of course, in the case that the mobile terminal includes only the first movable base 330 and the base is the fixed base 320, the driving body 310 may include a telescopic member, and the telescopic member applies the first traction force to the first movable base 330.

Referring to fig. 3 to 5, the embodiment of the present invention discloses a driving body 310 with a specific structure, and the disclosed driving body 310 includes a rope winding mechanism 311, a guide wheel 313, and a rope 312 partially wound around the rope winding mechanism 311. Of both ends of the pulling rope 313, one end may be connected to the first movable base 330 via a guide wheel 313, and the other end may be connected to the base or the second movable base 360 via another guide wheel 313. The rope 312 can be wound or unwound at both ends thereof by rotating the rope winding mechanism 311.

In a specific embodiment, the two ends of the pull rope 312 are respectively connected to the first movable base 330 and the second movable base 360. The rope 312 can be wound and unwound at both ends thereof by rotation of the rope winding mechanism 311. Rotation of the rope winding mechanism 311 can simultaneously release or retract the rope at both ends of the rope 312. When the winding mechanism 311 rotates in the direction of winding the rope, the pulling rope 312 is tightened, and the two ends of the pulling rope 312 apply a first traction force and a second traction force to the first movable seat 330 and the second movable seat 360, respectively. When the winding mechanism 311 rotates in the unwinding direction, the pull cord 312 is released, the first traction force applied to the first movable base 330 is removed after the pull cord 312 is released, and the second traction force applied to the second movable base 360 is removed.

Of course, when the mobile terminal only includes the first movable base 330, and the base is the fixed base 320, both ends of the pull rope 312 may be connected to the fixed base 320 and the first movable base 330, respectively, but in this state, the pull rope 312 is only used to pull the first movable base 330 to move.

When the mobile terminal has the structure shown in fig. 6, the base seat is the third movable seat 3110, and both ends of the pull rope 312 can be respectively connected with the first movable seat 330 and the third movable seat 3110 through the guide wheel 313, so that the first movable seat 330 and the third movable seat 3110 can be elastically separated from or approach to each other.

In this embodiment, the rope winding mechanism 311 has various structures, as long as it can wind or unwind the rope 312 at the same time in the process of winding or unwinding the rope. Referring to fig. 5, in a specific embodiment, the rope winding mechanism 311 may include a motor 311a, a speed reducer 311b, and a reel 311c, wherein the reel 311c is drivingly connected to the motor 311a through the speed reducer 311 b. The motor 311a can rotate bidirectionally, thereby realizing the winding and unwinding of the reel 311 c. Specifically, the reducer 311b may be a gear reducer. To improve the rotational accuracy, the motor 311a may be a stepping motor.

The mobile terminal disclosed in the embodiment of the present invention may further include a camera support 400, the camera 200 is mounted on the camera support 400, and the camera support 400 is connected to the driving mechanism 300. The driving mechanism 300 is indirectly connected to the camera 200 through the camera mount 400. The camera bracket 400 can facilitate the assembly of the camera 200. Generally, the camera support 400 has a frame structure, and can also play a role in protecting the camera 200.

The camera bracket 400 may be provided with a limiting portion 410, and the limiting portion 410 is used for limiting and matching with a perforated inner side port in a state that the camera 200 extends out of the perforation, so that excessive movement of the camera 200 can be avoided. In the process that the camera 200 is driven to extend, when the camera 200 extends to a position, the limiting part 410 can be in limiting fit with the inner side port of the through hole. The bore has an inner port and an outer port, the outer port being the other port of the bore, the outer port being a greater distance from the inner lumen 120 than the inner port.

In an optimal scheme, the limiting part 410 can be sealed and plugged between the edge of the inner port of the through hole and the camera support 400, in this case, the limiting part 410 not only can play a limiting role, but also can realize the sealing and plugging between the camera support 400 and the inner wall of the through hole, and achieve better dustproof and waterproof purposes. The structure of the limiting portion 410 has various structures, and in a specific embodiment, the limiting portion 410 can be a limiting sheet, which is thinner, so that the occupied space of the limiting portion 410 can be reduced.

The camera 200 can move by the driving of the driving mechanism 300. In general, the camera bracket 400 is slidably engaged with the housing 100, so as to drive the camera 200 to move relative to the housing 100. Typically, the housing 100 includes a slide rail disposed in the inner cavity 120, the slide rail extending along the moving direction of the camera, and the camera support 400 is slidably disposed on the slide rail. The camera bracket 400 may be slidably engaged with the housing 100 through a variety of structures. In a specific embodiment, the camera bracket 400 may be provided with guide rods 130 at both sides thereof, and the camera bracket 400 is provided with sliding sleeves 420, wherein the sliding sleeves 420 are sleeved on the corresponding guide rods 130. At this time, the guide bar 130 is a slide rail as described above.

The mobile terminal disclosed in the embodiment of the present invention may implement control of the driving main body 310 in various ways. Referring to fig. 3 and 4 again, in a specific implementation manner, the mobile terminal disclosed in the embodiment of the present invention may further include a first hall device 500, a magnet 600 and a controller 800, wherein the magnet 600 is disposed on the camera 200 and moves with the camera 200, and specifically, the magnet 600 may be a magnet. The first hall device 500 is disposed at an inner side of the bezel 110 (i.e., one side of the bezel 110 closer to the inner cavity 120, and the other side of the bezel 110 is located outside the mobile terminal), the controller 800 is connected to the first hall device 500, and the controller 800 controls the driving body 310 to be closed according to a magnetic flux change of the magnet 600 sensed by the first hall device 500.

During the process of extending the camera 200, the camera 200 approaches and gradually approaches the frame 110, and finally extends out of the through hole. In this process, the magnet 600 gradually approaches the first hall device 500 along with the camera 200, the magnetic flux of the magnet 600 that can be sensed by the first hall device 500 changes greatly, and when the limiting portion 410 is in limiting fit with the inner port of the through hole or the driving main body 310 pushes the camera 200 to the protruding limit position, the magnetic flux of the magnet 600 that can be sensed by the first hall device 500 does not change any more (that is, the magnetic flux changes to zero) or the magnetic flux changes less (for example, less than a threshold value preset by a designer), in this case, the controller 800 controls the driving main body 310 to close accordingly, and finally the driving of the camera 200 stops.

Of course, if the magnetic flux variation of the magnet 600 sensed by the first hall device 500 is large (for example, the magnetic flux is greater than zero or the magnetic flux variation is greater than the threshold value preset by the designer), it indicates that the camera 200 is not extended in place, and in this case, the controller 800 still controls the driving main body 310 to maintain the driving operation state.

Similarly, in a preferred embodiment, the mobile terminal disclosed in the embodiment of the present invention may further include a second hall device 700 connected to the controller, the second hall device 700 and the first hall device 500 are sequentially arranged in the moving direction of the camera 200, the first hall device 500 is disposed between the second hall device 700 and the frame 110, and the controller 800 controls the driving main body 310 to be turned off according to the magnetic flux change of the magnet 600 sensed by the second hall device 700.

In the process of retracting the camera 200, the magnet 600 gradually approaches the second hall device 700 along with the camera 200, the magnetic flux of the magnet 600 sensed by the second hall device 700 changes greatly, when the camera 200 is fully retracted into the inner cavity 120, and the camera 200 cannot drive the camera 200 to further retract (i.e. reaches the retraction limit position) through other component positioning or the driving mechanism 300, the magnetic flux of the magnet 600 sensed by the second hall device 700 does not change (i.e. the magnetic flux changes to zero) or the magnetic flux changes are small (e.g. smaller than a threshold value preset by a designer), in this case, the controller 800 controls the driving body 310 to close accordingly, and finally the driving of the camera 200 stops.

When the magnetic flux of the magnet 600 sensed by the second hall device 700 is changed greatly (for example, the magnetic flux is greater than zero or the magnetic flux change is greater than the threshold preset by the designer), the controller 800 controls the driving main body 310 to maintain the driving operation state accordingly.

Of course, it should be noted that, when the magnet 600 moves, the magnet 600 gradually approaches the first hall device 500, and then the controller 800 controls the driving body 310 according to the sensing result of the first hall device 500. The magnet 600 is gradually close to the second hall device 700, and the controller 800 controls the driving body 310 based on the sensing result of the second hall device 700.

There are various ways to achieve the above object, for example, a shielding member may be provided between the first hall device 500 and the second hall device 700, and when the magnet 600 passes through the shielding member to gradually approach the first hall device 500, the second hall device 700 does not sense the magnetic flux of the magnet 600, in which case the controller 800 can only control the sensing result of the first hall device 500. Also, when the magnet 600 passes through the shield to be gradually close to the second hall device 700, the first hall device 500 does not sense the magnetic flux of the magnet 600, and in this case, the controller 800 can control only the sensing result of the second hall device 700.

Of course, the controller 800 may select a control basis from the sensing results of the first hall device 500 and the second hall device 700 according to the position of the magnet 600. For example, when the magnet 600 is close to the first hall device 500, the controller 800 uses the sensing result of the first hall device 500 as the control basis; when the magnet 600 is close to the second hall device 700, the controller 800 controls based on the sensing result of the second hall device 700.
