Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of camera, and particularly relates to a camera module and a camera device. BACKGROUND

[0002] At present, the camera module can include an image sensor, a lens, and a voice coil motor sleeved on the outer wall of the lens.

[0003] The voice coil motor includes a stator, a rotor, a coil and a spring sheet. The coil is arranged on the rotor. The stator and the rotor are connected through the spring sheet. The rotor is connected with the lens. The driving principle of the voice coil motor is that a direct current is applied to the coil, so that the magnetic field generated by the coil interacts with the magnetic field generated by the permanent magnet arranged in the rotor, to drive the rotor and the lens to move, thereby realizing the focusing and zooming of the camera module.

[0004] However, according to the above method, since the voice coil motor is sleeved on the lens, and the radial size of the voice coil motor is large, the size of the camera module, especially the radial size, is large, and therefore how to reduce the size of the camera module is a problem to be solved. SUMMARY

[0005] The purpose of the embodiments of the application is to provide a camera module and a camera device, which can solve the problem of reducing the size of the camera module.

[0006] In a first aspect, the embodiments of the application provide a camera device, which includes an image sensor, a lens, a first driving assembly and a motor. The image sensor and the lens are arranged oppositely. The first driving assembly is connected with the side wall of the lens. The motor is connected with the first driving assembly. The motor is used to drive the first driving assembly to move along the axis of the lens, to drive the lens to move in the direction away from or close to the image sensor.

[0007] In a second aspect, the embodiments of the application provide a camera device, which includes the camera module as described in the first aspect.

[0008] In the embodiments of the application, since the first driving assembly connected with the side wall of the lens can be driven by the motor to move along the axis of the lens, to drive the lens group to move in the direction away from or close to the image sensor, the focusing or the fixed focus of the camera module can be realized. In this way, the voice coil motor in the prior art can be replaced by the combination structure of the motor + the driving assembly, so that the radial size of the camera module can be reduced.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0024] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a class, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0025] The embodiments provided by the present application will be described in detail below with reference to the drawings and specific embodiments and their application scenarios.

[0026] The embodiments provided by the present application provide a camera module, Figure 1 The structure of the camera module provided by the embodiments of the present application is shown in the structural schematic diagram, as shown in Figure 1As shown, the camera module 100 can include an image sensor 10, a lens 20, a first driving assembly 30, and a motor 40. The image sensor 10 is arranged opposite to the lens 20, the first driving assembly 30 is connected to a side wall of the lens 20, and the motor 40 is connected to the first driving assembly 30. The motor 40 is configured to drive the first driving assembly 30 to move along an axis of the lens 20, so as to drive the lens 20 to move away from or close to the image sensor 10.

[0027] In some embodiments of the present application, at least part of the first driving assembly is parallel to the axis of the lens, and the at least part is movable along the axis, so as to drive the lens connected to the at least part to move synchronously.

[0028] It can be understood that the rotation direction of the output shaft of the motor is different, and the moving direction of the lens is also different.

[0029] For example, the output shaft of the motor rotates in a first direction, so as to drive the lens to move away from the image sensor; the output shaft of the motor rotates in a second direction, so as to drive the lens to move close to the image sensor, and the first direction is opposite to the second direction.

[0030] For example, the first direction is clockwise, and the second direction is counterclockwise; or, the first direction is counterclockwise, and the second direction is clockwise.

[0031] In some embodiments of the present application, the first driving assembly can be directly connected or indirectly connected to the output shaft of the motor.

[0032] In some embodiments of the present application, the camera module can further include a housing with a second opening, and the lens, the image sensor, the first driving assembly, and the motor are arranged in the housing. The image sensor is arranged on a bottom wall of the housing corresponding to the second opening, and the motor is arranged on the bottom wall to avoid the image sensor.

[0033] In some embodiments of the present application, as shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 , the camera module 100 can further include a camera base 70, and the image sensor 10 is fixed on the camera base 70.

[0034] In some embodiments of the present application, as shown in Figure 1 or Figure 4 , the camera module 100 can further include a filter 60, and the filter 60 is arranged between the image sensor 10 and the lens 20, and the filter 60 is arranged on the camera base.

[0035] It can be understood that, since the camera module provided by the embodiments of the present application does not have a voice coil motor, the size of the motor carrier can be effectively thinned, or even the motor carrier can be cancelled, so that the size of the camera module in the X or Y direction can be reduced, thereby reducing the size of the camera module; in addition, the transmission noise of the camera module during focusing or zooming can also be reduced.

[0036] The first mode

[0037] In some embodiments of the present application, as shown in Figure 1 and Figure 2 The first driving assembly 30 can include a first transmission wheel 301 and a second transmission wheel 302 arranged along the axis of the lens 20, and a first transmission belt 303 sleeved on the first transmission wheel 301 and the second transmission wheel 302; the motor 40 is connected with the second transmission wheel 302, and a part of the first transmission belt 303 is connected with the side wall of the lens 20; wherein the motor 40 can be used to drive the second transmission wheel 302 to rotate, drive the first transmission belt 303 to rotate, and drive the lens 20 to move away from or close to the image sensor 10.

[0038] It can be understood that when the first driving assembly is directly driven by the motor, the second transmission wheel can be fixed on the output shaft of the motor.

[0039] In some embodiments of the present application, a part of the first transmission belt away from the surface of the transmission wheel can be connected with the side wall of the lens.

[0040] In some embodiments of the present application, a part of the first transmission belt and the side wall of the lens can be connected by adhesive.

[0041] It should be noted that the distance between the first transmission wheel and the second transmission wheel is greater than the maximum distance between the lens and the image sensor, so as to ensure that when the motor drives the first transmission belt to rotate around the first transmission wheel and the second transmission wheel, the first transmission belt can drive the lens to move along the axis of the lens.

[0042] In some embodiments of the present application, as shown in Figure 3C The first transmission belt 303 can be connected with the side wall of the lens 20 through the connecting member 90. Wherein the connecting member can be double-sided adhesive or glue.

[0043] In some embodiments of the present application, the width of the first transmission belt can be the same as the width of the side wall of the lens facing the first transmission belt, so as to improve the connection reliability between the first transmission belt and the lens.

[0044] It can be understood that the width of the first transmission wheel and the second transmission wheel is adapted to the width of the first transmission belt.

[0045] In some embodiments of the present application, the motor drives the second transmission wheel to rotate in the first direction, which can drive the first transmission belt to rotate around the first transmission wheel and the second transmission wheel in the first direction, thereby driving the lens to move away from the image sensor. Similarly, the motor drives the second transmission wheel to rotate in the second direction, which can drive the first transmission belt to rotate around the first transmission wheel and the second transmission wheel in the second direction, thereby driving the lens to move towards the image sensor. The first direction is opposite to the second direction.

[0046] In some embodiments of the present application, the distance between the first transmission wheel and the image sensor is greater than the distance between the second transmission wheel and the image sensor, that is, the second transmission wheel is closer to the image sensor.

[0047] In some embodiments of the present application, the first transmission wheel can be rotatably connected to the inner wall of the shell, for example, the first transmission wheel can be rotatably connected to the inner wall of the shell through the third transmission shaft.

[0048] Alternatively, the camera module can further include a first support parallel to the axis of the lens, the bottom of the first support is arranged on the bottom wall of the shell, the top of the first support is arranged with a fourth transmission shaft corresponding to the area of the first transmission wheel, the first transmission wheel can be sleeved on the fourth transmission shaft and fixedly connected with the fourth transmission shaft. It can be understood that the fourth transmission shaft can rotate with the first transmission wheel.

[0049] In this way, since the first transmission belt parallel to the length direction and the axis of the lens can be connected with the side wall of the lens, and the transmission wheel supporting the first transmission belt is driven to rotate by the motor, the lens can be driven to move away from or close to the image sensor, and the transmission wheel and the transmission belt are located on the side of the lens. Therefore, compared with the solution of sleeving the voice coil motor outside the lens, the radial size of the camera module provided by the embodiments of the present application is smaller.

[0050] In some embodiments of the present application, in order to improve the stability of the movement of the lens, in combination with Figure 1 and Figure 2 As shown in FIGS. 10 and 11, the camera module can further include a first transmission shaft 304, and a second driving assembly 31 whose movement direction is perpendicular to the first driving assembly 30.

[0051] The second driving assembly 31 is arranged on one side of the lens 20, and the second driving assembly 31 and the first driving assembly 30 are both connected with the first transmission shaft 304, and the motor 40 is connected with the second driving assembly 31.

[0052] The motor 40 is used to drive the second driving assembly 31 to move in a direction perpendicular to the axis of the lens, and drive the first driving assembly 30 to move along the axis of the lens.

[0053] In some embodiments of the present application, the second driving assembly and the first driving assembly are arranged vertically.

[0054] In some embodiments of the present application, as shown in Figure 1 and Figure 2 , the second driving assembly 31 can include: a third transmission wheel 306 and a fourth transmission wheel 307 arranged in sequence in a direction perpendicular to the axis of the lens, and a second transmission belt 410 sleeved on the third transmission wheel 306 and the fourth transmission wheel 307. Wherein, the first transmission shaft 304 is connected with the second transmission wheel 302 and the third transmission wheel 306 respectively, and the motor 40 is connected with the fourth transmission wheel 307.

[0055] It should be noted that, Figure 1 the rectangular dashed box 40 in is used to show the possible installation position of the motor 40. Specifically, when the camera module includes the first driving assembly, as shown in Figure 1 , the motor 40 is connected with the second transmission wheel 302, that is, the motor is arranged at the position shown by the rectangular dashed box 40 on the left side in Figure 1 . When the camera module includes the first driving assembly and the second driving assembly, as shown in Figure 1 , the motor 40 is connected with the second transmission wheel 302, that is, the motor 40 is arranged at the position shown by the rectangular dashed box 40 on the left side in Figure 2 .

[0056] In some embodiments of the present application, the first transmission belt and the second transmission belt are perpendicular.

[0057] In some embodiments of the present application, the first transmission shaft and the bottom wall of the shell can be rotatably connected, such as rotatably connected with the bottom wall of the shell through a bearing.

[0058] For other descriptions of the second driving assembly, refer to the related descriptions of the first driving assembly in the above embodiments, and to avoid repetition, it will not be described here.

[0059] It can be understood that when the camera module includes the first driving assembly and the second driving assembly, the first driving assembly is indirectly connected with the motor.

[0060] Therefore, since the first driving assembly and the second driving assembly can constitute an L-shaped driving mechanism, the stability and reliability of the lens movement can be improved.

[0061] In some embodiments of the present application, as shown in Figure 2 , the camera module 100 further includes: a second transmission shaft 305 and a third driving assembly 32 whose movement direction is perpendicular to the first driving assembly 30;

[0062] The second transmission shaft 305 is arranged on the side of the lens 20 opposite to the first transmission shaft 304, and the second transmission shaft 305 is arranged in parallel with the first transmission shaft 304; the third driving assembly 32 is arranged on the side of the lens 20 opposite to the second driving assembly 31, and the third driving assembly 32 is arranged in parallel with the second driving assembly 31; the second driving assembly 31 and the third driving assembly 32 are connected with the second transmission shaft 305, and the third driving assembly 32 is also connected with the first transmission shaft 304, the motor (not shown in the figure) and the second transmission shaft 305; Figure 2

[0063] The motor 40 is configured to drive the second driving assembly 31 and the third driving assembly 32 to move along the direction perpendicular to the axis of the lens through the second transmission shaft 305, and drive the first driving assembly 30 to move along the axis of the lens.

[0064] It can be understood that the second driving assembly is parallel to the second driving assembly, and the second driving assembly and the second driving assembly are both parallel to the first driving assembly.

[0065] In some embodiments of the present application, the second transmission shaft is rotatably connected with the bottom wall of the shell, for example, through a bearing.

[0066] Therefore, since the second driving assembly and the third driving assembly are parallel and both perpendicular to the first driving assembly, and the second driving assembly and the third driving assembly are respectively connected through the first transmission shaft and the second transmission shaft, the first driving assembly, the second driving assembly and the third driving assembly are connected through the first transmission shaft, so that the first driving assembly, the second driving assembly and the third driving assembly constitute a stable double-L type driving mechanism, and the stability and reliability of the lens movement can be further improved.

[0067] In some embodiments of the present application, as shown in Figure 1 and Figure 2 The first driving assembly 30, the second driving assembly 31 and the third driving assembly 32 are all driving assemblies, and each driving assembly includes one transmission wheel and two transmission belts; the first transmission shaft 304 is connected with one transmission wheel in each driving assembly, and the second transmission shaft 305 is connected with another transmission wheel in the second driving assembly 31 and another transmission wheel in the third driving assembly 32.

[0068] In some embodiments of the present application, as shown in Figure 2 ​As shown, when the camera module 100 includes the first driving assembly 30, the second driving assembly 31 and the third driving assembly 32, the first driving assembly 30 includes the first transmission wheel 301 and the second transmission wheel 302 arranged in sequence along the axis of the lens 20, and the first transmission belt 303 sleeved on the first transmission wheel 301 and the second transmission wheel 302; the second driving assembly 31 includes the third transmission wheel 306 and the fourth transmission wheel 307 arranged in sequence along the direction perpendicular to the axis of the lens, and the second transmission belt 410 sleeved on the third transmission wheel 306 and the fourth transmission wheel 307; the third driving assembly 32 includes the fifth transmission wheel 308 and the sixth transmission wheel 309 arranged in sequence along the direction perpendicular to the axis of the lens, and the third transmission belt 411 sleeved on the fifth transmission wheel 308 and the sixth transmission wheel 309; wherein the first transmission shaft 304 is connected with the second transmission wheel 302, the third transmission wheel 306 and the sixth transmission wheel 309 respectively, and the second transmission shaft 305 is connected with the fourth transmission wheel 307 and the fifth transmission wheel 308 respectively.

[0069] Thus, since the second transmission wheel, the third transmission wheel and the sixth transmission wheel are connected through the first transmission shaft, and the second transmission wheel is located between the third transmission wheel and the sixth transmission wheel, and the fourth transmission wheel and the fifth transmission wheel are connected through the second transmission shaft, and the second transmission shaft is connected with the motor, when the motor drives the first transmission shaft to rotate, the second transmission belt and the third transmission belt can more stably transmit power to the first transmission shaft, so that the movement of the first transmission belt is more stable, thereby making the movement of the lens more stable and reliable.

[0070] It can be understood that the transmission wheel + transmission belt mode can improve the transmission stability and reduce the transmission noise.

[0071] In some embodiments of the present application, the first transmission shaft is perpendicular to the third transmission belt and the second transmission belt.

[0072] For example, as shown in Figure 3B the sixth transmission wheel 309 is fixed on the first transmission shaft 304, the third transmission belt 411 is sleeved outside the sixth transmission wheel 309, and the first transmission shaft 304 is perpendicular to the third transmission belt 411.

[0073] As can be seen, the length direction of the first transmission belt is perpendicular to the length direction of the second transmission belt and the third transmission belt, and the second transmission belt and the third transmission belt are arranged in parallel.

[0074] In some embodiments of the present application, the width of the second transmission belt and the width of the third transmission belt are smaller than the width of the first transmission belt, so as to further reduce the radial dimension of the camera module.

[0075] In some embodiments of the present application, the width of the second transmission belt and the width of the third transmission belt can be the same.

[0076] In some embodiments of the present application, the transmission wheel can be a belt wheel, or the transmission wheel can be a gear wheel.

[0077] When the transmission wheel is a gear wheel, the surface of the transmission belt in contact with the transmission wheel is provided with teeth meshing with the gear wheel.

[0078] For example, as shown in Figure 3A the fourth transmission wheel 307 is a gear wheel, and the inner surface of the second transmission belt 410 is provided with teeth meshing with the gear wheel, so as to further improve the transmission progress.

[0079] In this way, each driving assembly in the first driving assembly, the second driving assembly and the third driving assembly includes a transmission belt and a transmission wheel, and the first transmission shaft is connected with one of the transmission wheels in each driving assembly, and the second transmission shaft parallel to the first transmission shaft is connected with the other transmission wheel in the second driving assembly and the third driving assembly. Since the transmission belt transmission is relatively stable and has less noise, the double-L-shaped driving mechanism composed of three belt wheel transmission assemblies not only can ensure the stable movement of the lens, but also can reduce the movement noise.

[0080] In some embodiments of the present application, as shown in Figure 1 and Figure 2 the camera module 100 can further include a support structure 412 arranged on the side of the image sensor 10 away from the lens 20. The support structure 412 is rotatably connected with the first transmission shaft 304 and the second transmission shaft 305, respectively.

[0081] In some embodiments of the present application, the region of the support structure corresponding to the first transmission shaft and the second transmission shaft can be provided with a connecting portion, respectively, and each connecting portion is provided with a connecting hole parallel to the first transmission shaft and the second transmission shaft. Thus, the support structure can be rotatably connected with the first transmission shaft and the second transmission shaft through the connecting hole.

[0082] For example, the support structure can be located between the bottom wall of the shell and the image sensor.

[0083] In some embodiments of the present application, the support structure can be a support plate parallel to the image sensor, or a support bracket.

[0084] In some embodiments of the present application, the support structure can be arranged on the bottom wall of the shell. Alternatively, the support structure can also be arranged on the surface of the camera base away from the image sensor. The actual use requirements can be determined.

[0085] For example, the support structure can be bonded to the surface of the camera base away from the image sensor by glue.

[0086] In some embodiments of the present application, the support structure can include a horizontal support portion and a vertical support portion connected together, wherein the horizontal support portion is used to be rotationally connected with the first transmission shaft and the second transmission shaft, and the vertical support portion can be rotationally connected with the first transmission wheel, for example, the vertical support portion can be the first support mentioned above.

[0087] It can be understood that the support structure can be used to position the horizontal and vertical angle position of the transmission belt, so as to realize the horizontal movement and vertical movement of the transmission belt.

[0088] Therefore, since the first transmission shaft and the second transmission shaft can be rotationally connected through the support structure, the angle error between the first transmission shaft and the second transmission shaft can be reduced, so as to improve the transmission stability, and thus the movement stability of the lens can be further improved.

[0089] It can be understood that the first mode provides a camera module using an L-shaped driving mechanism composed of at least one transmission belt and at least two transmission wheels to drive the movement of the lens, so as to realize the cancellation of the voice coil motor. Figure 2 It can be seen that through the cooperation between the first transmission wheel 301, the second transmission wheel 302, the first transmission shaft 304, the second transmission shaft 305, the third transmission wheel 306, the fourth transmission wheel 307, the fifth transmission wheel 308 and the sixth transmission wheel 309, the rotation of the motor 40 is converted into the movement of the first transmission belt 303 along the axis of the lens 20, so as to realize the movement of the lens 20. Therefore, not only the radial size of the camera module 100 can be reduced, but also the stable movement of the lens 20 can be ensured.

[0090] It can be understood that in the first mode, the process of realizing the close-up or telephoto shooting of the camera module is as follows: when receiving a close-up shooting instruction, the motor can drive the transmission wheel to rotate in the second direction, and through the first transmission belt, the lens is driven to move in the direction close to the image sensor, so as to realize the close-up shooting function. Therefore, since the stability and precision of the transmission belt can be ensured through the stability and precision of the rotation of the transmission wheel, precise and stable focusing can be realized.

[0091] When receiving a telephoto shooting instruction, the motor can drive the transmission wheel to rotate in the first direction, and through the first transmission belt, the lens is driven to move in the direction away from the image sensor, so as to realize the telephoto shooting function. Therefore, since the stability and precision of the transmission belt can be ensured through the stability and precision of the rotation of the transmission wheel, precise and stable focusing can be realized.

[0092] The second mode

[0093] In some embodiments of the present application, as Figure 4 and Figure 5As shown, the first driving assembly 30 can include a transmission member 413, a worm 414 and a turbine 415. The first part of the transmission member 413 is parallel to the axis and connected to the side wall of the lens 20, the worm 414 is engaged with the turbine 415, and the first end of the transmission member 413 is connected to the worm 414, and the turbine 415 is connected to the motor 40.

[0094] The motor 40 can be used to drive the turbine 415 to rotate, drive the worm 414 to move relative to the turbine 415, and drive the transmission member 413 to move along the axis of the lens 20. It should be noted that Figure 5 The dashed line in the above figure indicates the corresponding structure, such as the motor 40 being invisible or blocked to the user.

[0095] In some embodiments of the present application, the turbine can be connected to the output shaft of the motor.

[0096] In some embodiments of the present application, the motor can be arranged on the bottom wall of the housing.

[0097] In some embodiments of the present application, one end of the worm is connected to the transmission member, and the other end of the worm is connected to the output shaft of the motor.

[0098] In some embodiments of the present application, one end of the worm is fixedly connected to one end of the transmission member.

[0099] For example, as Figure 6A shown, one end of the worm 414 can be welded or bonded to one end of the transmission member 413.

[0100] In some embodiments of the present application, the worm is parallel or perpendicular to the first part.

[0101] In some embodiments of the present application, the worm and the transmission member can be integrally formed.

[0102] In some embodiments of the present application, in order to improve the connection reliability and connection strength of the transmission member and the side wall of the lens, the transmission member can be a transmission plate, so as to increase the connection area of the first part of the transmission member and the side wall of the lens.

[0103] In some embodiments of the present application, the worm and the transmission member can be integrally formed, or the worm and the transmission member can be fixed together by welding or other means.

[0104] In some embodiments of the present application, the transmission member can be in the form of a straight line (1) or an L shape (2).

[0105] In some embodiments of the present application, the transmission member is in the form of a straight line, the transmission member is arranged parallel to the axis of the lens, the first part of the transmission member is the part corresponding to the lens, the worm is connected to the bottom end of the transmission member, the worm wheel is engaged with the worm, and the output shaft of the motor is connected to the worm wheel. It can be understood that the axis of the worm wheel, the axis of the motor, the axis of the transmission member and the axis of the lens are parallel to each other. At this time, the worm wheel and the motor are arranged in a stacked manner in the axis direction of the lens.

[0106] In some embodiments of the present application, the transmission member is in the form of an L shape, and the transmission member can be bent. As shown in Figure 4 and 5 The camera module 100 can further include a support sleeve 50. The support sleeve 50 can include a first sleeve 51 and a second sleeve 52 connected in communication, the first sleeve 51 is parallel to the axis of the lens 20, the second sleeve 52 is perpendicular to the axis of the lens 20, and the first sleeve 51 is provided with a first opening 53 towards the area of the lens 20. The transmission member 413 is arranged in the support sleeve 50, and the transmission member 413 is connected to the side wall of the lens 20 through the first opening 53, one end of the transmission member 413 extends out of the second sleeve 52 and is connected to the worm 414, the worm 414 is engaged with the worm wheel 415, and the worm wheel 415 is connected to the motor 40.

[0107] The motor can be used to drive the worm wheel to rotate, drive the transmission member to move along the support sleeve 50, and drive the lens to move towards or away from the image sensor.

[0108] In some embodiments of the present application, the first sleeve 51 and the second sleeve 52 can constitute an L-shaped sleeve.

[0109] In some embodiments of the present application, the support sleeve is used to limit the movement trajectory of the transmission member.

[0110] In some embodiments of the present application, as shown in Figure 4 One end of the transmission member 413 extends out of the second sleeve 52 and is connected to one end of the worm 414, the other end of the transmission member 413 is located in the first sleeve 51, and can extend out of the first sleeve 51.

[0111] In some embodiments of the present application, as shown in Figure 6B The transmission member 413 and the side wall of the lens 20 can be connected by a connecting member 90, wherein the connecting member 90 can include glue or double-sided tape.

[0112] In some embodiments of the present application, in the above (2), the transmission member can be made of a bendable material. Alternatively, as shown in Figure 7As shown, the transmission member 413 can include a first transmission part 1, a second transmission part 2, and a third transmission part 3 made of a bendable material; one end of the third transmission part 3 is connected to one end of the first transmission part 1, and the other end of the third transmission part 3 is connected to one end of the second transmission part 2.

[0113] In the third transmission part 3, the side wall of the third transmission part 3 is connected to the side wall of the lens through the first opening 3.

[0114] In some embodiments of the present application, the bendable material can be any one of the following: a memory alloy, a thermoplastic polyurethane (TPU), or a thermoplastic polyurethane rubber, etc. The material can be bent and has a certain rigidity.

[0115] In some embodiments of the present application, the first transmission part and the second transmission part can be made of a rigid material, such as iron or steel, etc.

[0116] In some embodiments of the present application, the second transmission part is arranged at the connection between the first sleeve and the second sleeve, so that when the motor drives the worm to move, the second transmission part can convert the movement of the first transmission part in the horizontal direction to the movement of the third transmission part in the vertical direction.

[0117] In some embodiments of the present application, the second sleeve can be located below the image sensor.

[0118] For example, the second sleeve can be arranged on the bottom wall of the housing and located between the bottom wall of the housing and the camera seat.

[0119] In some embodiments of the present application, the cross section of the first sleeve and the second sleeve can be rectangular.

[0120] Therefore, the radial size of the camera module can be reduced by replacing the voice coil motor to drive the lens to move through the combination of the transmission member, the worm connected to the transmission member, the worm engaged with the worm, and the motor connected to the worm.

[0121] Further, the movement amount of the lens can be precisely controlled by controlling the displacement amount of the transmission member through the rotation amount of the turbine, so that the precision of the movement of the lens can be improved.

[0122] It can be understood that in the second mode, the process of realizing the close-up or telephoto shooting of the camera module is as follows: when receiving a close-up shooting instruction, the motor can drive the worm to move in the third direction, and drive the lens to move in the direction close to the image sensor through the transmission member, thereby realizing the close-up shooting function. Therefore, the movement stability and precision of the transmission member can be ensured through the transmission stability and precision of the turbine and the worm, thereby realizing precise and stable focusing.

[0123] When receiving the telephoto shooting instruction, the motor can drive the worm to move in the fourth direction, drive the lens to move away from the image sensor through the transmission member, and realize the close-up shooting function. In this way, the movement stability and precision of the transmission member can be ensured by the transmission stability and precision of the worm and the turbine, so as to realize accurate and stable focusing.

[0124] The motor can rotate in different directions according to different shooting instructions. For example, the motor can rotate clockwise when receiving the close-up shooting instruction, and the motor can rotate counterclockwise when receiving the telephoto shooting instruction.

[0125] In some embodiments of the present application, as shown in Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 The camera module 100 can further include at least one positioning column 416. The at least one positioning column 416 is arranged parallel to the axis of the lens 20, and the sidewall of the lens 20 is provided with at least one third sleeve 21, and each positioning column 416 is in sliding connection with one of the at least one third sleeve 21.

[0126] In some embodiments of the present application, when the number of positioning columns is multiple, the at least one positioning column is distributed circumferentially along the lens.

[0127] In some embodiments of the present application, the number of positioning columns can be one or two. Two positioning columns can be used to ensure the stability of the lens during movement and avoid tilting of the lens during movement.

[0128] In some embodiments of the present application, the at least one positioning column is symmetrically arranged with the part parallel to the axis of the lens in the first driving assembly.

[0129] In this way, since the camera module further includes at least one positioning column in sliding connection with the lens, the circumferential positioning and circumferential guiding of the lens can be realized through the at least one positioning column, so as to improve the focusing and zooming accuracy of the camera module.

[0130] In some embodiments of the present application, as shown in Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 The at least one positioning column 416 is integrally formed with the camera base 70 in the camera module 100, and the image sensor 10 is arranged on the camera base 70. In this way, the assembly error can be reduced, so as to improve the positioning accuracy of the positioning column 416 to the lens 20.

[0131] In some embodiments of the present application, as shown in Figure 1 andFigure 4 As shown, the camera module 100 can further include a circuit board 80 connected with the image sensor 10.

[0132] In some embodiments of the present application, the circuit board can be arranged on the camera base, or the circuit board can be arranged on the upper support structure to improve the fixing firmness of the circuit board.

[0133] In some embodiments of the present application, the circuit board can be bonded on the camera base by glue.

[0134] In the camera module provided in the embodiments of the present application, the first driving assembly connected with the side wall of the lens can be driven by the motor to move along the axis of the lens, and drive the lens group to move away from or close to the image sensor, so that the focusing or the fixed focus of the camera module can be realized. In this way, the voice coil motor in the prior art can be replaced by the combination of the motor and the first driving assembly, so that the radial size of the camera module can be reduced.

[0135] The embodiments of the present application further provide a camera device, which can include a frame 210, a display screen 220 and a camera module 100 as shown. Figure 8 As shown, the camera device 200 can include a frame 210, a display screen 220 and a camera module 100 as shown. Figures 1 to 7 The camera module 100 is arranged in the frame 210, and the display screen 220 is embedded on the frame 210.

[0136] It can be understood that, since there is no voice coil motor between the lens and the image sensor of the camera module, i.e. there is no magnet between the lens and the image sensor, when the camera device includes a plurality of the above-mentioned camera modules, there is no magnetic interference between the plurality of camera modules, so that the shooting effect of the camera device can be improved.

[0137] In the camera device provided in the embodiments of the present application, the first driving assembly connected with the side wall of the lens can be driven by the motor to move along the axis of the lens, and drive the lens group to move away from or close to the image sensor, so that the focusing or the fixed focus of the camera module can be realized. In this way, the voice coil motor in the prior art can be replaced by the combination of the motor and the first driving assembly, so that the radial size of the camera module can be reduced.
