The drive mechanism 30 includes a motor 31, a drive shaft 32, and a slider 33. One end of the drive shaft 32 is connected to the output shaft of the motor 31, so that the drive shaft 32 can rotate with the output shaft of the motor 31. It can be understood that the drive shaft 32 can be integrally formed with the output shaft or separately assembled with the output shaft. The slider 33 is threaded with the drive shaft 32. After the motor 31 drives the drive shaft 32 to rotate, the slider 33 can act on the drive shaft 32. The bottom moves linearly along the axial direction of the drive shaft 32.

When the slider 33 faces the lens module When 10 moves linearly, the slider 33 drives the second magnetic member 213 to move together, and the second magnetic member 213 drives the first magnetic member 212 to move by repulsive force, thereby driving the lens module 10 to move linearly together.

By providing the first magnetic member 212 and the second magnetic member 213, both of which are magnetic steel, the magnetic steel is a super-hard permanent magnetic alloy. Therefore, the hardness of the first magnetic member 212 and the second magnetic member 213 will be reduced. It is relatively large, and during the movement of the lens module 10, the first magnetic member 212 and the second magnetic member 213 will not be deformed, and the magnetic performance of the two is stable and will not weaken over time. Therefore, the first magnetic member 212 and the second magnetic member 213 are stable.

A notch 331 is provided, and the notch 331 is embedded in the annular groove 215. Therefore, when the slider 33 moves in the axial direction of the drive shaft 32, it will simultaneously drive the sleeve 214 to move, and then pass through the second magnetic member 213 and the first magnetic member. 212 drives the lens module 10 to move.

As an improvement of this embodiment, the support rod 211 includes a rod body 216 with one end connected to the lens module 10 and a boss 217 at the other end of the rod body 216. The bushing 214 is located between the boss 217 and the second magnetic member 213. The first magnetic member 212, the second magnetic member 213 and the shaft sleeve 214 are all sleeved outside the rod body 216.

The rod body 216 and the boss 217 are preferably integrally formed to ensure the strength of the support rod 211. When the slider 33 moves linearly in a direction away from the lens module 10, it will drive the shaft sleeve 214 to move together, and the shaft sleeve 214 moves to and After the boss 217 abuts, the sleeve 214 can no longer move relative to the support rod 211, thereby driving the support rod 211 to move together, and the support rod 211 drives the lens module 10 to move, thereby retracting the lens module 10 into the receiving cavity 203 .

Please refer to FIGS. 3 and 6, as an improvement of this embodiment, the first transmission assembly 21 further includes a support sleeve 218, and the support sleeve 218 includes a first cylinder that is arranged outside the support rod 211 and connected to the lens module 10 219 and a second cylinder 220 extending from one end of the first cylinder 219 toward the slider 33. The second cylinder 220 is provided with a cavity 221 for accommodating the first magnetic member 212 and the second magnetic member 213.

When the second magnetic member 213 pushes the first magnetic member 212 to move, when the first magnetic member 212 moves to abut the support sleeve 218, the first magnetic member 212 will push the support sleeve 218 to move together, thereby pushing the lens mold The group 10 moves, and by adjusting the height of the second cylinder 220, the initial position of the first magnetic member 212 can be adjusted.

As an improvement of this embodiment, the first transmission assembly 21 further includes a screw cap 222 for threaded connection with the end of the second cylinder 220 away from the first cylinder 219, and the screw cap 222 is provided in communication with the cavity 221 The through hole 223 of the shaft sleeve 214 can be movably penetrated through the through hole 223. The second cylinder 220 is provided with a through groove 224 communicating with the cavity 221. The through groove 224 is away from the second cylinder 220 from the first cylinder 219 One end of the tube extends toward the first cylinder 219.

In this embodiment, the diameter of the second cylinder 220 is greater than the diameter of the first cylinder 219, the end of the second cylinder 220 away from the first cylinder 219 is provided with an external thread, the screw cap 222 is annular, and the screw cap 222 The middle part of the second cylinder 220 is provided with a groove opening toward the second cylinder 220, and the groove wall of the groove is provided with an internal thread that matches the external thread. Insert the end of the second cylinder 220 into the groove, and then rotate the second cylinder 220. The cylinder 220 is threadedly connected to the supporting sleeve 218 and the screw cap 222, the screw cap 222 can support the supporting sleeve 218 to a certain extent, and since the side wall of the second cylinder 220 is provided with a through groove 224, The through groove 224 extends from the end of the second cylinder 220 away from the first cylinder 219 toward the first cylinder 219. In this way, the second cylinder 220 has a certain degree of elasticity, and the second cylinder 220 can face perpendicular to the A certain deformation is produced in the extending direction of the through groove 224, which can reduce the diameter of the bottom end of the second cylinder 220, facilitate the insertion of the second cylinder 220 into the groove, and also improve the adaptability of the support sleeve 218.

The length of the support base 225 is greater than the length of the opening 204. Therefore, when the support base 225 moves to the annular frame 202, the limiting extension 227 will abut against the annular frame 202, thereby preventing the support base 225 from continuing to move outward. That is, the lens module 10 is prevented from continuing to move linearly outward.

It is understandable that the positioning of the support seat 225 is not limited to the annular frame 202. For example, it is also possible to separately provide a stopper on the receiving housing 200 that is directly opposite to the support seat 225.

When the slider 33 moves linearly toward the lens module 10, the first transmission assembly 21 is driven to move together. , The first transmission component 21 pushes the lens module 10 to move, the lens module 10 drives the second transmission component 23 to move, the slider 33, the first transmission component 21, the lens module 10, and the second transmission component 23 are not generated at this stage Relative movement, so the lens module 10 will only move in a straight line and not rotate. When the support base 225 abuts the ring frame 202, the support base 225 is blocked, the support base 225 stops moving linearly, and the support rod 211, the lens The module 10 and the second transmission assembly 23 also stop linear movement, the slider 33 continues to move toward the lens module 10, and the second magnetic part 213 is pushed to move relative to the first magnetic part 212 through the sleeve 214, so that the slider 33 and The second transmission assembly 23 generates a relative movement and causes the threaded section 233 to form a threaded fit with the second threaded hole 338. The screw 231 is driven by the slider 33 to rotate, and the screw 231 drives the lens module 10 to rotate through the gear set 232 In this way, the linear motion and rotation of the lens module 10 are completely separated, and the lens module 10 will not produce linear motion when rotating, thereby ensuring the shooting quality of the camera device 100.

It can be understood that the threaded section 233 did not form a threaded fit with the second threaded hole 338 at the beginning. This may be due to the axial distance between the threaded section 233 and the second threaded hole 338, that is, the threaded section 233 is not inserted into the second threaded hole 338. In the threaded hole 338, therefore, no threaded fit is formed; it is also possible that the threaded section 233 is inserted into the second threaded hole 338, but the second threaded hole 338 is only provided with a thread that cooperates with the threaded section 233 in the middle or lower part, so no thread is formed Cooperate.

The side plate 42 and the second side plate 43 protruding from the other side of the base plate 41 and spaced opposite the first side plate 42. The slider 33 is located between the first side plate 42 and the second side plate 43, and the guide rod 50 The sliding block 33 can be movably passed through, and the two ends of the guide rod 50 are respectively fixed to the first side plate 42 and the second side plate 43.

One end of the drive shaft 32 is rotatably connected to the first side plate 42, and the other end passes through the second side plate 43 and is connected to the reduction box 34. The guide rod 50 is spaced apart on the side of the drive shaft 32 away from the screw 231. The guide rod 50 can be The sliding block 33 is guided to move along its axial direction, thereby making the sliding block 33 run more smoothly, that is, making the lens module 10 run more smoothly.

Preferably, the first magnetic member 212 and the second magnetic member 213 can also cooperate with a Hall element to achieve the function of detecting the position of the lens module 10. For example, a Hall sensor can be installed on the motor 31, or the bracket 40 or the back shell 200. During the linear movement of the lens module 10, the first magnetic member 212 and the second magnetic member 213 will face the Hall sensor together with the slider 33. The sensor moves, therefore, the combined magnetic field formed by the first magnetic member 212 and the second magnetic member 213 at the Hall sensor is always changing, and the Hall sensor detects the change of the combined magnetic field to obtain the straight line of the lens module 10 Displacement; when the lens module 10 rotates, the slider 33 will drive the second magnetic member 213 to move relative to the first magnetic member 212, so the combined magnetic field of the first magnetic member 212 and the second magnetic member 213 at the Hall sensor will also When a change occurs, the Hall sensor detects the change of the combined magnetic field to obtain the rotation angle of the lens module 10.

Please refer to FIG. 3 and FIG. 9 to FIG. 13, the process of pushing out, rotating, reversing, and retracting the lens module 10 will be described in detail below.

The electronic device 1 receives the first control instruction and sends the first execution instruction to the driving mechanism 30;

The motor 31 receives the first execution quality and drives the drive shaft 32 to rotate. Since the slider 33 and the drive shaft 32 are threaded, the slider 33 will move linearly toward the lens module 10 under the action of the drive shaft 32. 33. The second magnetic member 213 is driven to move by the shaft sleeve 214. The second magnetic member 213 drives the first magnetic member 212 to move together by repulsive force. The first magnetic member 212 is blocked by the support sleeve 218 and cannot move relative to the support rod 211. The support sleeve 218 pushes the support seat 225 to move, the support seat 225 drives the support rod 211 and the second transmission assembly 23 to move together, and the second gear 235 pushes the lens module 10 out of the receiving cavity 203 to a predetermined position; at this time, the support seat 225 abuts against the ring frame 202.

After the support base 225 abuts against the ring frame 202, the motor 31 continues to work, and the slider 33 continues to move linearly toward the lens module 10. At this time, the support base 225 is blocked by the ring frame 202 and can no longer move outwards. The block 33 drives the shaft sleeve 214 to move relative to the support base 225, and the shaft sleeve 214 pushes the second magnetic member 213 to move relative to the first magnetic member 212, so that the distance between the first magnetic member 212 and the second magnetic member 213 is reduced. The repulsive force between 212 and the second magnetic member 213 increases, so that the first magnetic member 212 presses the support seat 225 on the annular frame 202 through the support sleeve 218, and at the same time, the slider 33 and the screw rod 231 form a threaded fit, and the screw rod 231 Under the action of the slider 33, the screw rod 231 drives the second gear 235 to rotate through the first gear 234, and the second gear 235 drives the lens module 10 to rotate by a predetermined angle.

The electronic device 1 receives the second control instruction and sends the second execution instruction to the driving mechanism 30;

After the motor 31 receives the second execution command, the drive shaft 32 is driven to rotate in the reverse direction, and the slider 33 moves linearly in a direction away from the lens module 10 under the action of the drive shaft 32 and the first magnetic member 212 and the second magnetic member 213. The slider 33 drives the shaft sleeve 214 to move away from the lens module 10, and the second magnetic member 213 moves along with the shaft sleeve 214 under the action of the first magnetic member 212, but at this time, the first magnetic member 212 and the second magnetic member 212 move together with the shaft sleeve 214. There is still a large repulsive force between the parts 213, the first magnetic part 212 still presses the support base 225 on the annular frame 202 through the support sleeve 218, the screw 231 rotates in the opposite direction under the action of the slider 33, and drives the first magnetic part 212. A gear 234 rotates in the reverse direction, and the first gear 234 drives the lens module 10 to reversely rotate a predetermined angle through the second gear 235; at this time, the screw 231 and the slider 33 are out of threaded cooperation, and the lens module 10 stops rotating in the reverse direction.

After the lens module 10 rotates in the reverse direction by a predetermined angle, the motor 31 continues to drive the drive shaft 32 to rotate in the reverse direction, and the slider 33 is driven by the drive shaft 32 to continue to move linearly in the direction of the lens module 10 while driving the shaft sleeve 214 to move together. After the sleeve 214 moves to abut the boss 217, the sleeve can no longer move relative to the support rod 211, so it will drive the support rod 211 to move together, the support rod 211 drives the support base 225 to move, and the support base 225 drives the second transmission assembly 23 and the lens module 10 move in a straight line until the lens module 10 is retracted to the initial position in the receiving cavity 203.

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. The scope of protection.
