Referring to fig. 1 and 2, the rear cover 320 covers a side of the bezel 311 away from the display screen 200. In this embodiment, the frame 311 and the rear cover 320 are two independent parts, and in other embodiments, the frame 311 and the rear cover 320 are integrally formed.

In other words, the lens module is a lens of the rear camera. In other embodiments, the location of the mounting holes 420 includes, but is not limited to, being either side of the bezel 311, or a corner of the bezel 311, etc.

Referring to fig. 4 and 5, the retractable camera assembly 100 includes a housing case 1, a lens module 2, a photosensitive module 3, a supporting frame 4 and a driving module 5.

Referring to fig. 2 and 4, the receiving case 1 is mounted in the mounting hole 420 and fixed with respect to the rear cover 320. The housing case 1 has a housing cavity 1 a. The accommodating cavity 1a is used for accommodating the lens module 2, the photosensitive module 3, the supporting frame 4 and the driving module 5.

Referring to fig. 6, the accommodating case 1 includes a top plate 111 and a bottom plate 112 disposed opposite to each other, and a peripheral side plate 113 connected between the top plate 111 and the bottom plate 112. The top plate 111 and the peripheral side plate 113 may be integrally formed, and the bottom plate 112 may be fixedly connected to the peripheral side plate 113 by means of fastening, screwing, or the like. The top plate 111 includes an outer wall 111a and an inner wall 111b opposite to each other, and an opening 111c penetrating the outer wall 111a and the inner wall 111 b. The opening 111c communicates with the housing chamber 1 a. The surface of the bottom plate 112 facing the top plate 111 is a bottom wall, and the bottom wall is also a surface of the bottom plate 112 facing the opening 111 c.

Referring to fig. 7 in combination, at least one guide post 114 is disposed in the receiving case 1 (i.e., in the receiving cavity 1 a). The guide posts 114 are disposed along the Z-axis direction. Optionally, the guiding column 114 may be integrally formed with the peripheral side plate 113, or both ends of the guiding column 114 are fixedly connected to the top plate 111 and the bottom plate 112, respectively.

Referring to fig. 8 and 9, at least a portion of the lens module 2 is located in the accommodating case 1. Specifically, the lens module 2 includes a lens housing (not shown) and a lens group (not shown) disposed in the lens housing. The optical axis direction of the lens group is the positive direction of the Z axis. The size of the outer peripheral surface of the lens module 2 is matched with the size of the opening 111c, so that the lens module 2 can extend out or retract through the opening 111c, and the integrity of the appearance is kept.

Referring to fig. 8, 9 and 10, the photosensitive module 3 is fixed in the housing case 1 and disposed opposite to the lens module 2. Specifically, the photosensitive module 3 includes, but is not limited to, an image sensor 31, a flexible circuit board 32 electrically connected to the image sensor 31, and the like. The image sensor 31 is disposed on the flexible circuit board 32, and the image sensor 31 and the lens set are disposed opposite to each other along the Z-axis direction. The photosensitive module 3 may further include a steel patch of the flexible circuit board 32. Wherein the steel is supplemented to the side of the flexible circuit board 32 facing away from the image sensor 31. Optionally, the photosensitive module 3 may further include a filter 33. The filter 33 is disposed between the image sensor 31 and the lens set. The filter 33 includes, but is not limited to, an infrared filter 33 to filter the infrared light emitted through the lens assembly, so that the visible light emitted into the image sensor 31 has less impurities.

Referring to fig. 5 and fig. 6, the position of the photosensitive module 3 fixed to the accommodating case 1 will not be described in detail. In the present embodiment, the bottom plate 112 has a stepped hole 112a communicating with the accommodating cavity 1a, and the outer peripheral edge of the photosensitive module 3 is engaged with the inner peripheral edge of the stepped hole 112 a. To seal the stepped hole 112a, the image sensor 31 of the photo module 3 is located in the accommodating cavity 1a and opposite to the lens group. In the present embodiment, the photo-sensing module 3 can be assembled to the housing case 1 through the stepped hole 112a from the outside of the housing case 1, and thus, a portion of the photo-sensing module 3 is exposed outside the housing case 1 to be electrically connected to the electrical connection structure on the middle frame 310 of the electronic device 1000. Of course, in other embodiments, the photosensitive module 3 may also be fixed on the side of the bottom plate 112 facing the top plate 111.

In the embodiment of the present application, the photosensitive module 3 and the lens module 2 form a camera module. The camera module comprises but is not limited to a main camera, a wide-angle camera, a long-focus camera, a macro camera and the like.

The supporting frame 4 is located between the lens module 2 and the photosensitive module 3. The supporting frame 4 supports the lens module 2. The supporting frame 4 is fixedly connected to one side of the lens module 2 facing the bottom plate 112. The supporting frame 4 is a hollow structure.

Specifically, referring to fig. 5, the supporting frame 4 has a supporting frame hole 4a, and the supporting frame hole 4a corresponds to the lens group of the lens module 2 and the image sensor 31 of the photosensitive module 3, so that the light of the lens group is emitted to the image sensor 31 through the supporting frame hole 4 a. Alternatively, the supporting frame 4 may be disposed substantially along the X-Y plane, the supporting frame 4 is supported at the bottom of the lens module 2, and when the supporting frame 4 moves along the Z-axis direction, the lens module 2 also moves along the Z-axis direction.

Referring to fig. 5 and 10, the driving module 5 is connected to the supporting frame 4, and the supporting frame 4 is slidably connected to the guiding post 114. The driving module 5 is used for driving the supporting frame 4 to slide along the guiding column 114 and move relative to the photosensitive module 3, so as to drive the lens module 2 to extend out of the accommodating case 1 or retract into the accommodating case 1.

In the present embodiment, the driving module 5 is connected to the lens module 2 through the supporting frame 4. Because support frame 4 is the guide post 114 of accommodating the shell 1 still sliding connection, so, support frame 4 still slides along guide post 114 when receiving drive module 5's drive power, guide post 114 extends along the Z axle direction, give support frame 4 the direction of following the motion of Z axle direction, so that support frame 4 slides along following the Z axle direction, make lens module 2 flexible along the Z axle direction from accommodating shell 1's opening 111c, prevent that it from taking place the card at flexible in-process and dying scheduling problem, improve the flexible smoothness nature and the flexible stationarity of lens module 2.

It can be understood that the guiding post 114 can provide guiding for the supporting frame 4 along the Z-axis direction, and the guiding post 114 increases the guiding function when the lens module 2 is ejected, so as to prevent the lens module 2 from deflecting or tilting and affecting the movement of the lens module 2; on the other hand, the movement of the support frame 4 in the X-Y plane can be limited.

In other words, the lens module 2 can extend out or retract into the accommodating case 1 along the optical axis direction under the driving of the driving module 5, and since the photosensitive module 3 is fixed to the accommodating case 1, the lens module 2 can move relative to the photosensitive module 3 along the optical axis direction, or the image distance (or back focal length) of the lens module 2 changes along with the extension and retraction of the lens module 2. Therefore, the camera module in which the lens module 2 is located is also called a retractable camera module or an extendable camera module. It can be understood that the number of the retractable camera modules in the electronic device 1000 is one or more.

The lens module 2 has at least two states including an extended state and a retracted state with respect to the photosensitive module 3 (or with respect to the housing case 1). The following description will be given taking as an example a state in which the lens module 2 is extended to the maximum extension process, but the extended state in the present application may be a state in which the lens module is extended but does not reach the maximum extension process. The lens module 2 moves from the retracted state to the extended state, and optical zooming of the camera module is achieved.

Referring to fig. 11 to 13, when the lens module 2 is in the extended state, the lens module 2 is in the imaging position of the camera module, and at this time, the camera module is in the operable state. Referring to fig. 8 to 10, when the lens module 2 is in the retracted state, the camera module is in the non-working state, i.e., the storage state.

In the electronic device with a fixed camera proposed in the general technology, because the module thickness of the camera is limited by the lightness and thinness of the electronic device (the thickness of the electronic device), after the module thickness of the camera is limited, the light-sensing area of the camera is also limited accordingly, so that the light-sensing area of the camera is relatively small, and the imaging definition, the fidelity and the like of the camera are influenced to a certain extent. Moreover, the existing camera is very sensitive to height, and an excessively high module can cause the rear cover of the electronic equipment to form a sharp bulge, which affects the appearance of the whole appearance of the electronic equipment such as a mobile phone.

This application can follow one side that back lid 320 deviates from display screen 200 through the lens module 2 of the scalable camera subassembly 100 of design, when scalable camera subassembly 100 is in the state of stretching out, for the module thickness of the normal work of scalable camera subassembly 100, that is to say, the module thickness of scalable camera subassembly 100 no longer receives the restriction of electronic equipment 1000's thickness, has realized that the module thickness of scalable camera subassembly 100 is great relatively and electronic equipment 1000's thickness is less compatibility relatively. Because the retractable camera assembly 100 has a relatively large thickness in the extended state, the size of the photosensitive module 3 of the retractable camera assembly 100 can be set to be relatively large (i.e., the large-sized image sensor 31), so that the lighting area of the retractable camera assembly 100 is relatively large, and a better quality image can be obtained. In the present embodiment, the surface on which the photosensitive module 3 is located is substantially parallel to the X-Y plane, and the electronic apparatus 1000 itself has a large space on the X-Y plane, so the electronic apparatus 1000 also has the potential to accommodate a large photosensitive module 3. When the retractable camera assembly 100 is in the retracted state, the lens module 2 retracts to be accommodated in the accommodating space 410, and at this time, the retractable camera assembly 100 does not form a protruding protrusion on the rear cover 320, which is beneficial to good appearance of the electronic device 1000 and touch feeling of hand touch of a user; moreover, the guide posts 114 are arranged in the accommodating shell 1, the support frame 4 capable of sliding along the guide posts 114 is arranged between the driving module 5 and the lens module 2, and the driving module 5 provides driving force for the support frame 4 to slide along the guide posts 114, so that the support frame 4 can stably slide along the extending direction of the guide posts 114, and the telescopic smoothness and smoothness of the lens module 2 relative to the accommodating shell 1 are improved.

In addition, compared with the scheme that the rear cover 320 extends from the side of the housing 300, in the scheme that the camera module extends from the side, because the extending direction of the camera module intersects with the facing direction of the camera module, the camera module extends integrally, that is, the lens module 2 and the photosensitive module 3 extend together, and the requirements of zooming the lens module 2 relative to the photosensitive module 3 and setting the outsole image sensor 31 when the camera module extends cannot be met; still because relations such as cell-phone thickness, lens module 2 and drive module 5 can only be along the direction mode of arranging that stretches out, consequently, whole camera subassembly is great relatively in the ascending size in the direction of stretching out, and the scalable camera subassembly 100 that this embodiment provided not only can realize lens module 2 and zoom when stretching out and can set up the demand of big end image sensor 31, can also effectually avoid the too big problem of scalable camera subassembly 100 in the electronic equipment 1000 in the direction of stretching out.

When the lens module 2 is in the state of stretching out, the total length of the optical system of the camera module is increased, longer focal length design can be realized during optical design, and longer focal length is favorable for improving the performance of the optical system and exceeding the optical blurring effect after the depth of field, the optical blurring effect can obtain more real and flamboyant photos than the algorithm blurring effect, because the optical blurring effect is different according to the distance of the actual scenery completely, errors can not appear because of the complexity of the scenery, so the embodiment of the application stretches out the camera module to increase the focal length through designing, and can realize the imaging effect of higher definition and reality.

In the present embodiment, referring to fig. 10 and fig. 13, the supporting frame 4 is located at the bottom of the lens module 2.

Referring to fig. 14, the supporting frame 4 is substantially square. Four extending portions 41 extend from four corners of the support frame 4 toward the support frame hole 4 a. The four extensions 41 each extend toward the center of the holder hole 4 a. The bottom of the lens module 2 is provided with groove portions 21 corresponding to the four extending portions 41. Each extending portion 41 is disposed in one of the recessed portions 21, so that the lens module 2 and the supporting frame 4 are aligned accurately and do not move in the X-Y plane. In addition, the bottom of the lens module 2 is further provided with a pair of positioning posts 22 spaced from the recessed portion 21, and the positioning posts 22 are diagonally arranged. The supporting frame 4 is provided with a positioning hole 42 corresponding to the positioning post 22. The positioning posts 22 are cylinders, one of the positioning holes 42 is a circular hole, and the other positioning hole 42 can be a long hole, so as to eliminate the problem that the two positioning posts 22 cannot be installed in the two positioning holes 42 due to manufacturing tolerance. Of course, in other embodiments, the extending portion 41 may be disposed at the bottom of the lens module 2, and the groove portion 21 may be disposed on the supporting frame 4.

The supporting frame 4 and the lens module 2 can be fixed together by welding or dispensing.

Optionally, referring to fig. 7, 10 and 13, at least one guiding column 114 is located on a side of the supporting frame 4 away from the driving module 5. Taking a guide post 114 as an example, the driving module 5 and the guide post 114 are respectively located at two opposite sides of the supporting frame 4. For example, the driving module 5 and the guiding column 114 are arranged along the X-axis direction, and the supporting frame 4 is kept stable under the action of the driving module 5 and the guiding column 114 in the X-axis direction. Further, the guide posts 114 can also apply forces to the support frame 4 in the positive Y-axis direction and the negative Y-axis direction, so that the support frame 4 is stabilized in the Y-axis direction by the forces of the guide posts 114. The guide post 114 is used for limiting the support frame 4 in the X-axis direction and the Y-axis direction, so that the support frame 4 can stably slide along the Z-axis direction under the guide of the guide post 114 and the action of the driving module 5, and further the lens module 2 is driven to stably extend and retract. Compared with the implementation mode of pushing the lens module 2 out through the spring, the spring force pushing out may cause the lens module 2 to be unbalanced in stress and easy to incline and clamp, and compared with the implementation mode, the implementation mode can increase the extending stability of the lens module 2.

Optionally, the guiding column 114 is protruded from the sidewall of the accommodating case 1. The side wall of the housing case 1 is a wall surface of the peripheral side plate 113. Further, the guide posts 114 may be integrally formed with the side wall of the receiving case 1. The shape of the guide post 114 is not particularly limited in the present application. Alternatively, the guide posts 114 are small half cylinders, large half cylinders, etc. having a cylindrical configuration.

Further, referring to fig. 10, 13 and 14, the side of the supporting frame 4 is provided with a notch 4b adapted to the guiding post 114. The support frame 4 is engaged with the guide post 114 through the notch 4 b. In this way, the guide post 114 limits the X-axis direction and the Y-axis direction of the support frame 4.

In the present embodiment, the guide post 114 is disposed on the side wall of the accommodating case 1, which facilitates the integral molding of the guide post 114 and the accommodating case 1, and simplifies the processing of the guide post 114; on the other hand, the guide posts 114 are arranged next to the side walls of the housing case 1, so that the space occupied by the guide posts in the housing case 1 is reduced, and the position interference of other devices caused by the arrangement of the guide posts 114 is reduced. The support frame 4 is in clearance fit with the guide posts 114 by arranging the notches 4b matched with the guide posts 114 on the side surface of the support frame 4, so that the guide posts 114 can guide the movement of the support frame 4.

In another embodiment, the guide posts 114 are fixedly connected between the top plate 111 and the bottom plate 112 at both ends thereof, and the support frame 4 is provided with guide holes (not shown). The guide holes are in clearance fit with the guide posts 114. The guide posts 114 are arranged through the guide holes, and the support frame 4 is slidably connected with the guide posts 114 through the guide holes.

Alternatively, the number of the guide posts 114 may be plural. For example, the number of the guide posts 114 is three, and the three guide posts 114 and the driving module 5 are respectively disposed on four sides of the supporting frame 4 to limit the periphery of the supporting frame 4, so as to improve the sliding stability of the supporting frame 4.

Optionally, the number of the guide posts 114 may also be two, and the guide posts 114 are arranged diagonally, so that the two guide posts 114 can limit the X-axis direction and the Y-axis direction of the support frame 4, and further improve the sliding stability of the support frame 4 relative to the guide posts 114.

The present application does not limit the position and structure of the driving module 5. The structure of the driving module 5 provided in the present application is illustrated below with reference to the accompanying drawings.

Referring to fig. 15, the driving module 5 is disposed on one side of the supporting frame 4. In other words, the driving module 5 is disposed on one side of the lens module 2. With such an arrangement, the thickness of the retractable camera assembly 100 in the retractable direction can be reduced, so that the retractable camera assembly can be applied to a thinner electronic device 1000, and the electronic device 1000 can be thinned and developed. The driving module 5 is defined on the first side 43 of the supporting frame 4. The driving module 5 is arranged on one side of the lens module 2 on the X-Y plane. The extending direction of the first side 43 is defined as the Y-axis direction.

Specifically, referring to fig. 16 and 17, the driving module 5 includes a driving housing 51, a driving cover 52, a transmission rod 53, a motion block 54 and a driving unit 55. Specifically, the drive cover 52 is engaged with the drive case 51. The drive cover 52 is located on a side of the drive housing 51 facing away from the base plate 112 and forms an internal cavity. The transmission rod 53, the motion block 54 and the driving unit 55 are disposed in the inner cavity formed by the driving shell 51 and the driving cover 52.

The transmission lever 53 is provided along the optical axis direction (Z-axis direction) of the lens module 2. Two ends of the transmission rod 53 are respectively and rotatably connected with the bottom of the driving shell 51 (the bottom of the driving shell 51 is opposite to the driving cover 52) and the driving cover 52, and the rotation process of the transmission rod 53 is autorotation.

Referring to fig. 10, 13 and 17, the moving block 54 is screwed to the transmission rod 53. Alternatively, the transmission rod 53 is a screw rod, and the motion block 54 is a screw rod having an internal thread, which forms a threaded connection with an external thread on the screw rod. When the transmission lever 53 rotates (autorotates), the moving block 54 ascends or descends along the transmission lever 53 (with the positive Z-axis direction as the ascending direction) with the rotation of the transmission lever 53. The motion block 54 is also connected to the support frame 4, specifically to the first side 43 of the support frame 4. The driving unit 55 includes, but is not limited to, a micro motor, etc. The driving unit 55 is used for driving the transmission rod 53 to rotate (rotate) in the accommodating case 1, so that the moving block 54 moves (moves up and down) along the transmission rod 53, and drives the lens module 2 to extend out of the accommodating case 1 or retract into the accommodating case 1 along the Z-axis direction. Alternatively, when the driving unit 55 drives the transmission rod 53 to rotate to the motion block 54 to directly or indirectly abut against the driving cover 52, the lens module 2 is extended to the maximum extended position. When the driving unit 55 drives the transmission rod 53 to rotate until the motion block 54 directly or indirectly abuts against the bottom of the driving shell 51 (the bottom of the driving shell 51 is opposite to the driving cover 52), the lens module 2 retracts into the accommodating shell 1.

Referring to fig. 17, the driving module 5 further includes a transmission member 60 connected between the driving unit 55 and the transmission rod 53. Alternatively, the rotation axis of the driving unit 55 is disposed along the Z-axis direction and toward the extending direction of the lens module 2. One end of the transmission member 60 is connected to the rotation shaft of the driving unit 55, and the other end of the transmission member 60 is connected to the transmission rod 53. The driving unit 55 drives the transmission rod 53 to rotate by the transmission member 60, so that the moving block 54 moves along the transmission rod 53. In the present embodiment, the transmission levers 53 are provided adjacent to the drive unit 55 and are aligned in the extending direction (in the Y-axis direction) of the first side 43. One part of the transmission member 60 is connected to one end of the driving unit 55 facing the object side, and the other part of the transmission member 60 is sleeved on the transmission rod 53 and rotates coaxially with the guide rod.

Optionally, referring to fig. 17, the transmission member 60 includes a first gear 61, a second gear 62, and at least one third gear 63 engaged between the first gear 61 and the second gear 62. The first gear 61 is located at one end of the driving unit 55 facing the object side, and the first gear 61 is disposed coaxially with the rotation shaft of the driving unit 55. The rotation shaft of the driving unit 55 drives the first gear 61 to rotate synchronously around the Z-axis direction. The third gear 63 is located at an end of the transmission lever 53 toward the object side, and is disposed coaxially with the transmission lever 53. The gear radius of the first gear 61 is smaller than that of the second gear 62, so that the speed of the first gear 61 transmitted to the second gear 62 is relatively low, but the torque force is large; and/or the gear radius of the first gear 61 is smaller than that of the third gear 63, so that the speed of the transmission from the first gear 61 to the third gear 63 is relatively small, but the torsion is large. The number of the third gears 63 is one or more. When there is one third gear 63, the third gear 63 is meshed with both the first gear 61 and the third gear 63. The gear radius of the first gear 61 is smaller than that of the third gear 63, and the gear radius of the third gear 63 is smaller than that of the second gear 62. The gear radii of the first gear 61, the third gear 63 and the second gear 62 are gradually reduced to gradually reduce the gear rotation speed and gradually increase the gear rotation torque, and the rotation torque provided to the transmission rod 53 is increased to make the driving module 5 provide a large enough driving force for the lens module 2 to extend and retract, thereby improving the extension and retraction stability of the lens module 2.

When the third gear 63 is plural, the third gear 63 may be engaged with each other in the X-Y plane or may be coaxially connected in the Z-axis direction. The third gears 63 may have different sizes, for example, the radius of one third gear 63 in mesh connection with the first gear 61 is smaller than the radius of another third gear 63 in mesh connection with the second gear 62, so that the rotation speed of the gears is gradually reduced and the rotation torque of the gears is gradually increased.

The number of gears is not particularly limited in the present application. This application is different through the diameter of design gear to realize gear reduction, and then increase gear drive's drive power size, so that drive module 5 provides great thrust relatively.

In this embodiment, the rotation shaft of the driving unit 55 is disposed along the Z-axis direction, and in other embodiments, the rotation shaft of the driving unit 55 may also be disposed along the Y-axis direction, that is, the driving unit 55 is disposed transversely, and the worm wheel and the worm are engaged to convert the rotation around the Z-axis direction, and then the transmission member 60 is engaged to transmit the transmission to the moving block 54. When the driving unit 55 is transversely disposed, the thickness of the driving module 5 in the Z-axis direction can be reduced to gradually reduce the thickness of the outer contour of the retractable camera assembly 100, and the thickness of the retractable camera assembly 100 is reduced in a stepwise manner.

Further, referring to fig. 17 and 18, the driving module 5 further includes a limiting member 56. The limiting member 56 is located on one side of the moving block 54 facing the extending direction of the lens module 2. The limiting piece 56 is in threaded connection with the transmission rod 53, and the limiting piece 56 is used for limiting the movement block 54 from rising to the highest position.

The limiting member 56, the moving block 54 and the supporting frame 4 are equivalent to a whole, and the movement of the moving block 54 drives the lens module 2 to move, so that the lens module 2 is popped up. When the lens module 2 is retracted, the motor rotates reversely, the moving block 54 moves toward the bottom of the driving housing 51, and drives the lens module 2 to move toward the bottom plate 212, so that the lens module 2 returns to the original position.

Optionally, the limiting member 56 is made of an elastic material, and the limiting member 56 can not only limit the movement block 54 when it rises to the highest position, but also reduce the impact force on the movement block 54 when the movement block 54 rises to the highest position, so as to avoid the sudden stop of the lens module 2 when it extends to the maximum extending position, and gradually reduce the speed to stop.

Referring to fig. 17 and 18, the driving module 5 further includes a guide rod 57. The guide rod 57 is fixed to the housing case 1 and is provided along the optical axis direction of the lens module 2. Both ends of the guide rod 57 are fixed between the bottom of the driving case 51 and the driving cover 52, respectively. The guide rod 57 extends in the same direction as the transmission rod 53. The guide lever 57 is located on the side of the transmission lever 53 facing away from the drive unit 55. The guide rod 57 is a slide rod. The moving block 54 is sleeved on the guide rod 57 and slidably connected with the guide rod 57. Specifically, the aperture of the through hole of the guide rod 57, which is sleeved with the moving block 54, is matched with (clearance fit with) the aperture of the guide rod 57, so that the moving block 54 moves relative to the guide rod 57 along the Z-axis direction, and the moving block 54 is limited to rotate relative to the X-Y plane. Alternatively, the guide rod 57 may be a circular rod or a square rod, which is not particularly limited in the present application. The guide rods 57 ensure that the motion block 54 moves along the Z-axis without movement in other directions, such as flipping, rotating, etc.

The retractable camera assembly 100 also includes a controller (not shown). The controller is electrically connected with the driving unit 55, the controller controls the rotating shaft of the driving unit 55 to rotate, the rotating shaft of the driving unit 55 drives the first gear 611 to rotate around the Z axis, and then the third gear 63 and the second gear 62 are sequentially driven to rotate; the second gear 62 rotates to drive the transmission rod 53 to rotate, and since the motion block 54 is in threaded connection with the transmission rod 53, the transmission rod 53 rotates around the Z axis to drive the motion block 54 to move up and down along the transmission rod 53, that is, the motion block 54 moves along the Z axis along with the rotation axis of the transmission rod 53. When the moving block 54 moves in the positive direction of the Z axis, the moving block 54 drives the lens module 2 to extend out of the accommodating case 1 through the supporting frame 4. When the moving block 54 moves in the opposite direction of the Z-axis, the moving block 54 drives the lens module 2 to retract to the accommodating case 1 through the supporting frame 4.
