The push block body 51 is provided with a first threaded hole 511 that is threaded with the screw 600. The push block body 51 is sleeved It is on the screw 600 and can move along the axial direction of the screw 600, and is threadedly connected with the screw 600 through the first threaded hole 511. The side of the first extension 52 facing the back plate 11 is recessed away from the back plate 11 to form a first A guide hole 521. The first guide hole 521 is designed as a stepped hole to facilitate fixing the sleeve 84. The second extension 53 is provided with a second threaded hole 531. Understandably, the threaded connection does not have to be in the push block 500. A threaded hole is provided on the upper part. For example, a nut can be installed on the push block 500, and the nut can be threadedly connected with the screw rod 600.

One end of the screw 600 is rotatably connected with the first side plate 22, and the other end is rotatably connected with the second side plate 23. The push block 500 cooperates with the screw 600 to transform the rotational motion into linear motion.

The driving mechanism 700 includes a power supply component 71, a motor 72, and a reduction box 73. One end of the screw 600 is connected to the motor 72 through the reduction box 73, and the motor 72 is electrically connected to the power supply component 71. When the motor 72 drives the screw 600 to rotate, push The block 500 will move linearly along its axial direction under the drive of the screw 600, and drive the first transmission assembly 800, the second transmission assembly 900, the support 400 and the lens module 300 to move linearly together.

The first elastic member 82 and the second elastic member 83 are both springs, and the first elastic member 82 and the second elastic member 83 are subjected to a pre-compression force when they are installed. When the pushing block 500 pushes the lens module 300 outward under the action of the screw 600, the pushing block 500 generates a thrust on the sleeve 84, but the pushing force is not enough to compress the first elastic member 82, so the sleeve 84 cannot The first guide rod 81 generates relative movement, and the thrust will be transmitted to the support 400 through the sleeve 84 and the first elastic member 82, thereby driving the support 400 and the first guide rod 81 to move linearly toward the opening 14 to move the lens mold When the group 300 is pushed out of the accommodating cavity 13, when the push block 500 retracts the lens module 300 under the action of the screw 600, the push block 500 will generate a pushing force on the sleeve 84, but the pushing force is not enough to compress the second elastic member 83. Therefore, the sleeve 84 cannot move relative to the first guide rod 81, and the thrust will drive the first guide rod 81 through the sleeve 84 to drive the support 400 away from the opening 14 to move linearly, so as to retract the lens module 300 to the initial stage. position.

It should be noted that the arrangement of the first guide rod 81 is to provide a pulling force to the supporting member 400 so that the lens module 300 can be retracted into the receiving cavity 13 from the outside of the back shell 100, and the first elastic member 82 does not have to be It is sleeved on the first guide rod 81, and only needs to be supported between the support 400 and the push block 500 to provide thrust for the support 400 so that the lens module 300 can extend out of the back shell 100, and is the push block 500 The position space for linear movement is provided to enable the lens module 300 to realize the function of forward flip. Similarly, the second elastic member 83 does not have to be sleeved on the first guide rod 81, but only needs to be supported by the push block 500 and Between the limit parts 811, a position space for the push block 500 to move linearly is provided to enable the lens module 300 to realize the function of reverse flipping. The first elastic element 82 and the second elastic element 83 are sleeved on the first guide rod 81 only to better fix the first elastic element 82 and the second elastic element 83 and avoid the first elastic element 82 and the second elastic element 83 is deviated by force. Of course, there can be many ways to fix the first elastic element 82 and the second elastic element 83. For example, a fixed shaft can be added to fix the first elastic element 82 and the second elastic element 83, or A spring seat is added to the push block 500 and the support member 400 to fix the first elastic member 82 and the second elastic member 83 respectively.

The second guide rod 91 cooperates with the push block 500 for transmission to transform the linear motion into a rotary motion. It is understandable that the threaded connection does not necessarily require a threaded hole on the push block 500. For example, the push block 500 may be provided with threaded holes. A nut is installed on the upper part, and the nut is threadedly connected to the second guide rod 91.

The transmission pair 93 includes a first gear set 94, a second gear set 95 and a protective cover 96.

Therefore, the second guide rod 91 can be moved in the vertical direction (that is, parallel to the first direction Y). The direction of rotation) is converted into a rotation around the horizontal direction (that is, around the direction parallel to the second direction X). The rotation around the horizontal direction is transmitted to the output shaft 92 through the second gear set 95, so that the output shaft 92 rotates around the horizontal direction. It rotates and drives the lens module 300 to flip forward or backward relative to the support 400.

The second gear set 95 includes a first spur gear 951, a second spur gear 952 fixed to an end of the output shaft 92 away from the lens module 300, and connected to the first spur gear 951 and the first spur gear 951. The third spur gear 953 is between the two spur gears 952 and meshes with the first spur gear 951 and the second spur gear 952 respectively. The first spur gear 951 and the second bevel gear 942 are coaxially arranged, and the first spur gear 951 is in the first spur gear 951. Driven by the second bevel gear 942, it rotates in the horizontal direction, the third spur gear 953 is driven by the first spur gear 951 to rotate in the horizontal direction, and the second spur gear 952 is driven by the third spur gear 953 to rotate in the horizontal direction. Therefore, the output shaft 92 is driven to rotate in the horizontal direction, and the lens module 300 is flipped forward or backward relative to the support 400 under the drive of the output shaft 92; the second gear set 95 is configured as three spur gears, which helps to reduce The overall volume of the second gear set 95.

When the coil 104 is energized, the iron core 103 and the magnetic member 101 generate an adsorption force, so that the support member 400 is restricted and the current to the coil 104 is disconnected. , The iron core 103 and the magnetic member 101 have no attraction or repulsive force, so that the support member 400 can move freely. The magnetic member 101 and the electromagnet 102 are provided to realize the reverse flip of the lens module 300. When the lens module 300 needs to be reversed When turning over, the iron core 103 and the magnetic member 101 generate adsorption force to limit the support 400. On the basis that the support 400 is limited, the screw 600 rotates in the reverse direction, and the screw 600 drives the push block 500 to compress the first The two elastic members 83 move linearly away from the lens module 300, thereby driving the second transmission component 900 to rotate and drive the lens module 300 to reversely flip a predetermined angle. When the lens module 300 needs to be retracted, the coil 104 is supplied with a reverse current, At this time, the iron core 103 and the magnetic member 101 have no attraction or repulsive force, so that the support member 400 can move freely, and the lens module 300 can be driven by the driving mechanism 700 to retract into the electronic device 1.

In particular, it is sufficient to keep the relative position of the magnetic part 101 and the electromagnet 102. The positions of the magnetic part 101 and the electromagnet 102 can be interchanged, that is, the magnetic part 101 can be arranged in the groove 441, and the electromagnet 102 can be embedded in the surrounding wall 12. The position setting of the magnetic part 101 and the electromagnet 102 only needs to satisfy that when the lens module 300 rotates in the reverse direction, the magnetic part 101 and the electromagnet 102 are attracted so that the support part 400 is pressed against the surrounding wall 12, and the support part 400 is not in contact with the surrounding wall 12. The requirement for relative movement to occur.

Preferably, the electronic device 1 further includes a third guide rod 105, the third guide rod 105 is located on the side of the screw 600 close to the first guide rod 81, one end of the third guide rod 105 is connected to the first side plate 22, and the other end Connected to the second side plate 23, the push block main body 51 has a second guide hole 512 through it, the third guide rod 105 passes through the second guide hole 512, and the push block 500 moves linearly under the guidance of the third guide rod 105. Make the process of pushing out, retracting and turning over the lens module 300 more stable.

The following is a detailed description of the pushing out, forward flipping, reverse flipping and retracting processes of the lens module 300:

Push-out process: After the motor 72 starts to work, the gearbox 73 decelerates and increases the torque and transmits it to the screw 600 to make the screw 600 rotate in the positive direction. The push block 500 moves linearly toward the port 14 under the drive of the screw 600 to push the block. 500 pushes the pre-compressed first elastic member 82 toward the opening 14, the lift is transmitted to the support member 400, and the support member 400 drives the lens module 300, the first transmission assembly 800 and the second transmission assembly 900 to move toward the opening 14. When the lens module 300 moves for a certain distance, the first stop 44 of the support 400 is restricted and can no longer move toward the opening 14. At this time, the lens module 300 is just pushed out of the accommodating cavity 13, and the iron core 103 and the magnetic The piece 101 is magnetically attracted. During this process, the push block 500 and the second guide rod 91 have no relative movement. Therefore, the lens module 300 only moves linearly without rotating.

As shown in FIGS. 8 and 9, at this time, the lens module 300 is in an overturned state.

Forward flip process: In this embodiment, the forward flip of the lens module 300 is defined as the lens module 300 flips counterclockwise around an axis parallel to the second direction X. After the lens module 300 is pushed out of the accommodating cavity 13, the support member 400 is fixed to the surrounding wall 12 by the adsorption of the iron core 103 and the magnetic member 101, which can improve the safety and stability of the lens module 300, and the motor 72 continues to work. The screw 600 rotates forward, the screw 600 drives the push block 500 to move toward the lens module 300, the first elastic member 82 is compressed by the push block 500, but due to the limitation of the support 400, the push block 500 and the second guide rod 91 Relative motion converts linear motion into rotational motion. The second guide rod 91 drives the first bevel gear 941 to rotate. The second bevel gear 942 meshes with the first bevel gear 941 for transmission, and converts the rotation around the vertical direction into the horizontal direction. The second gear set 95 drives the output shaft 92 to rotate in the horizontal direction, thereby driving the lens module 300 to flip forward relative to the support 400 to realize the tilting shooting function. When the pushing block 500 continues to move to the corresponding position, The lens module 300 will be flipped to the front camera state, flipped 360° state. When the motor 72 drives the screw 600 to rotate in the opposite direction, the push block 500 moves away from the lens module 300 under the action of the screw 600, that is, moves toward the inside of the electronic device 1, thereby driving the second guide rod 91 to rotate in the opposite direction. The first gear set 94 is driven to rotate in the reverse direction, and the output shaft 92 is driven to rotate in the reverse direction through the second gear set 95, thereby driving the lens module 300 to rotate and reset.

Reverse turning process: In this embodiment, the reverse turning of the lens module 300 is defined as turning the lens module 300 clockwise around an axis parallel to the second direction X. After the lens module 300 is pushed out of the accommodating cavity 13, the support member 400 is fixed to the surrounding wall 12 by the adsorption effect of the iron core 103 and the magnetic member 101, and cannot move freely. The motor 72 drives the screw 600 to rotate in the reverse direction, and the screw 600 drives the screw 600. The pushing block 500 moves away from the lens module 300, and the second elastic member 83 is compressed by the pushing block 500. However, due to the limitation of the supporting member 400, the pushing block 500 and the second guide rod 91 move relative to each other, converting linear motion into rotational motion. The second guide rod 91 drives the first bevel gear 941 to rotate, and the second bevel gear 942 meshes with the first bevel gear 941 for transmission, converts the rotation around the vertical direction into the rotation around the horizontal direction, and is driven by the second gear set 95 The output shaft 92 rotates in the horizontal direction, thereby driving the lens module 300 to reversely flip relative to the support 400 to realize the tilting shooting function. When the push block 500 is continuously moved to the corresponding position, the lens module 300 will flip to the forward shooting state. Turn 360° state. When the motor 72 drives the screw 600 to rotate in the opposite direction, the push block 500 moves toward the lens module 300 under the action of the screw 600, that is, moves toward the inside of the electronic device 1, thereby driving the second guide rod 91 to rotate in the opposite direction. The first gear set 94 is driven to rotate in the reverse direction, and the output shaft 92 is driven to rotate in the reverse direction through the second gear set 95, thereby driving the lens module 300 to rotate and reset.

Further, before the reverse reversal, the forward current is applied to the coil 104, which can strengthen the adsorption force of the magnetic member 101 and the iron core 103.

Retraction process: Reverse current is applied to the coil 104, the iron core 103 and the magnetic part 101 have no attraction or repulsion, The motor 72 drives the screw 600 to rotate in the reverse direction. The screw 600 drives the push block 500 to move away from the lens module 300 for linear motion. The push block 500 drives the first guide rod 81 through the second elastic member 83 to drive the support 400 and the lens module 300 Synchronously move linearly until the lens module 300 is retracted into the electronic device 1 through the port 14.

The electronic device 1 uses the lens module 300 through expansion and reversal. Therefore, the electronic device 1 can achieve a true full screen, which improves the aesthetics of the electronic device 1.
