The drive shaft 21 is preferably a screw rod, and one end of the drive shaft 21 penetrates After passing through the slider 22, it is connected with the reduction box 24, and the drive shaft 21 is threadedly connected with the slider 22. Therefore, when the drive shaft 21 rotates, the slider 22 will move linearly along the axial direction of the drive shaft 21 and drive the transmission mechanism 30. The linear motion is synchronized with the camera mechanism 10, and at the same time, the reduction box 24 will reduce the speed and increase the torque of the rotation output of the motor 23, so that the drive shaft 21 can obtain a greater torque.

Understandably, it is not necessary to install nuts in the slider body 221 and the second driving portion 223. For example, a through hole is provided in the corresponding part of the slider body 221 and the second driving portion 223, and a thread is also provided on the wall of the through hole. It is possible.

Please refer to Figures 1, 2 and 3, the transmission mechanism 30 includes a first transmission assembly 31 and a second transmission assembly 32. One end of the first transmission assembly 31 is connected to the first driving portion 222 of the slider 22, and the other end passes through the second The transmission component 32 is connected with the camera mechanism 10 to drive the camera mechanism 10 for linear motion. The second transmission component 32 is connected with the camera mechanism 10 for driving the camera mechanism 10 to rotate. When the camera mechanism 10 is pushed out to a designated position in a linear motion , The slider 22 drives the second transmission assembly 32 to rotate, thereby driving the camera mechanism 10 to rotate. This design method enables the camera mechanism 10 to perform linear motion and rotation, which enriches the functions of the camera device 100. When the user needs to use the shooting function of the electronic device 1, he can shoot different images without rotating the entire electronic device 1. The angled pictures are convenient for users to use and enhance the user's operating experience.

Referring to Figures 2, 3 and 4, the first transmission assembly 31 includes a support base 311, a support rod 312, a spring 313, and a sleeve 314. The support base 311 is located on the side of the camera mechanism 10 close to the drive mechanism 20 and passes through the second The transmission assembly 32 is connected to the camera mechanism 10, one end of the support rod 312 is connected to the support base 311, and the other end is connected to the first driving portion 222 through a sleeve 314. The sleeve 314 and the spring 313 are both sleeved on the outer periphery of the support rod 312, The two ends of the spring 313 are respectively connected with the support seat 311 and the sleeve 314. When the slider 22 moves outward along the axial direction of the drive shaft 21, the slider 22 generates a thrust on the sleeve 314, which acts on the spring 313. , The spring 313 pushes the support base 311 and the support rod 312 to linearly move, and the support base 313 pushes the camera mechanism 10 out to a predetermined position through the second transmission assembly 32. Referring to Figures 2, 3 and 5, the support rod 312 includes a rod body 3121 and a boss 3122. The rod body 3121 is connected between the boss 3122 and the support seat 311. The sleeve 314 is sleeved on the rod body 3121. The sleeve 314 includes The cylinder 3141 and the first convex ring 3142 and the second convex ring 3143 located at both ends of the cylinder 3141, the second convex ring 3143 abuts the boss 3122, the first driving part 222 of the slider 22 is engaged in the first through the gap Between the convex ring 3142 and the second convex ring 3143, one end of the spring 313 is connected with the first convex ring 3142. When the drive shaft 21 rotates in the opposite direction, the slider 22 will move downward and drive the sleeve 314 to move together. When the sleeve 314 moves until the second convex ring 3143 abuts the boss 3122, the sleeve 314 will be blocked by the boss 3122 and can no longer move relative to the support rod 312, thereby driving the support rod 312, the support seat 311 and the camera mechanism 10 Moving down, the camera mechanism 10 is finally retracted into the electronic device.

It is understandable that the sleeve 314 is not limited to the cylindrical body 3141, the first convex ring 3142, and the second convex ring 3143. For example, the sleeve 314 may only include the cylindrical body 3141 and the first convex ring 3142.

Referring to FIGS. 1, 2 and 5, the support base 311 includes a main body portion 3111 and a limiting extension portion 3112. In this embodiment, the limiting extension portions 3112 are preferably two and are respectively located on opposite sides of the main body portion 3111; The width of the opening 204 is greater than the width of the camera mechanism 10 and smaller than the width of the support base 311. Therefore, the camera mechanism 10 can freely pass through the opening 204, but the support base 311 cannot. When the support base 311 moves to the opening 204, the position is limited. The extension 3112 will be blocked by the frame 201 and stop the linear movement of the support base 311, so that the camera mechanism 10 and the second transmission assembly 32 also stop linear movement. At this time, the camera mechanism 10 is just pushed out to a predetermined position.

2 and 3, the second transmission assembly 32 includes a screw 321 and a gear set 322. One end of the screw 321 close to the slider 22 is provided with an external thread 3211 for meshing with a nut in the second driving part 223 of the slider 22 The gear set 322 includes a first gear 3221 and a second gear 3222 meshing with the first gear 3221. The first gear 3221 is fixed to the other end of the screw 321, and one end of the second gear 3222 extends into the camera mechanism 10. The meshing part of the gear 3221 and the second gear 3222 is located in the support base 311, and the support base 311 is connected to the camera mechanism 10 through the second gear 3222, and one end of the second gear 3222 extending into the camera mechanism 10 is provided with a first limiting portion 3223, the housing 11 of the camera mechanism 10 is aligned with a second limiting portion 111 that cooperates with the first limiting portion 3223, and the first limiting portion 3223 and the second limiting portion 111 are preferred in this embodiment It is flat, its structure is simple, and it is easy to produce. When the camera mechanism 10 is pushed out to a predetermined position, the support base 311 will be blocked by the frame 201 and can no longer move linearly. However, because the motor 23 continues to work, the slider 22 will still move linearly and drive the sleeve 314 to squeeze. Press the spring 313 to deform the spring 313. When the slider 22 moves a certain distance, the external thread 3211 on the screw 321 engages with the nut in the second driving part 223 of the slider 22, and the screw 321 will be driven by the slider 22 It rotates and drives the first gear 3221 on the screw 321 to rotate. The first gear 3221 drives the second gear 3222 to rotate. Due to the cooperation of the first limiting portion 3223 and the second limiting portion 111, the second gear 3222 is During the rotation, the camera mechanism 10 is driven to rotate together.

It is understandable that the screw 321 and the sliding block 22 can be screwed together in a manner that the screw 321 does not contact the sliding block 22 at the beginning, but when the supporting seat 311 abuts the frame body 201, the supporting seat 311 can no longer move linearly. The camera mechanism 10 and the second transmission assembly 32 also stop linear movement, but as the slider 22 continues to move linearly, it will press the spring 313 through the sleeve 314, causing the slider 22 to move linearly relative to the screw 321, so that the screw 321 The upper external thread 3211 is matched with the nut thread in the second driving part 223, and then the screw 321 can be rotated under the drive of the slider 22; it can also be: the end of the screw 321 with the external thread 3211 is always in the second driving In the nut of the part 223, only the middle or upper part of the nut is provided with threads. That is, the screw 321 is not initially matched with the nut threads, but simply inserted into the nut. When the slider 22 moves linearly relative to the screw 321 for a certain distance , The external thread 3211 of the screw 321 is threadedly matched with the nut in the second driving part 223.

3 and 6, the guide mechanism 40 includes a bracket 41 and a guide rod 42 mounted on the bracket 41. The bracket 41 includes an end plate 411 and two side plates 412 bent at both ends of the end plate 411. The two ends are respectively fixed on the two side plates 412, the slider 22 is located between the two side plates 412, and one end of the guide rod 42 passes through the slider body 221 of the slider 22, so that the slider 22 is on the guide rod 42. The linear motion is guided under the guidance, so that the pushing out and retracting process of the camera device 100 is more stable.

The process of pushing out, rotating and retracting the camera mechanism 10 will be described in detail below.

Please refer to Figure 2, Figure 3 and Figures 7 to 11, after the motor 23 works, the output of the motor 23 is transmitted to the drive shaft 21 through the reduction box 24 after deceleration and torque increase, so that the drive shaft 21 rotates in one direction, and the slider 22 is in Driven by the drive shaft 21, it moves outwards linearly. The slider 22 drives the camera mechanism 10 to move outwards through the first transmission assembly 31, and drives the second transmission assembly 32 to move outwards through the support base 311. When the camera mechanism 10 After moving for a certain distance, the support base 311 of the first transmission assembly 31 will be blocked by the frame body 201 and can no longer move outwards. At this time, the camera mechanism 10 is just pushed out to a predetermined position;

When the motor 23 continues to work, the slider 22 continues to move outward. At this time, the support base 311 is blocked by the frame 201 and can no longer move outward. Therefore, the slider 22 and the support base 311 move relative to each other, and the slider 22 drives the sleeve. During the outward movement of 314, the spring 313 will be squeezed to deform the spring 313. When the slider 22 moves a certain distance, the end of the screw 321 enters the inside of the slider 22, and passes through the external thread 3211 and the second driving part 223 internal nut thread Connected, so the slider 22 will drive the screw 321 to rotate when it moves linearly, and the first gear 3221 is fixed on the screw 321, so the first gear 3221 will follow the screw 321 to rotate together, thereby driving the second gear 3222 to rotate , Due to the limiting effect of the first limiting portion 3223 and the second limiting portion 111, the second gear 3222 cannot rotate relative to the camera mechanism 10, but can only drive the camera mechanism 10 to rotate together;

When the motor 23 drives the drive shaft 21 to rotate in the opposite direction, the two ends of the spring 313 squeezed during the above-mentioned rotation press against the support base 311 and the slider 22, respectively. During this process, the support base 311 is pressed by the spring 313 and does not When the downward displacement occurs, that is, so that the camera mechanism 10 does not undergo downward displacement, the slider 22 is pushed by the compression spring 313 and moves downward under the action of the drive shaft 21, thereby driving the screw 321 to rotate in the opposite direction. The gear set 322 is driven to rotate in the reverse direction, thereby driving the camera mechanism 10 to rotate in the reverse direction. When the camera mechanism 10 rotates to the original position in the reverse direction, the screw 321 and the slider 22 are disengaged from the threaded cooperation, the screw 321 no longer rotates, and the slider 22 continues downward Movement to make the sleeve 314 abut the boss 3122 of the support rod 312. At this time, while the slider 22 drives the sleeve 314 to move downward, it will also drive the support rod 312 to move downward, thereby driving the support base 311 and the camera mechanism. 10 moves downward, and finally retracts the camera device 100 into the receiving cavity 203.

Embodiment two:

12, the camera device 300 provided in this embodiment is compared with the camera device 100 provided in the first embodiment: the camera device 300 further includes a stop 50, the stop 50 is fixedly arranged relative to the motor 23', and the stop 50 is arranged at intervals The limiting extension portion 3112' is away from the side of the elastic member 313'. There are two stoppers 50. Each stopper 50 is directly opposite to a limit extension 3112'. The distance between the two stoppers 50 is greater than the width of the camera mechanism 10' but smaller than the width of the support base 311'. When the support base 311' moves to abut the stop 50, the support base 311' stops linear movement through the cooperation of the stop 50 and the limiting extension 3112'. The stop 50 may be integrally formed with the housing of the terminal device, for example, integrally formed with the frame of the first embodiment.

It is understandable that the installation method of the stopper 50 is not limited to the above, and it can also be fixedly connected to the fixed part of the camera device 300, for example, the stopper 50 is fixedly connected to the motor 23', or the stopper 50 can be connected to the bracket. 41' is fixedly connected, as long as the stop 50 can be fixed.

The above are only the embodiments of the present invention. It should be pointed out here that for those of ordinary skill in the art, improvements can be made without departing from the inventive concept of the present invention, but these all belong to the present invention.
