Wherein, the lens assembly 1 is located on the optical path of the photosensitive assembly 2, and the photosensitive assembly 2 generates an induction signal for imaging based on the external environment light obtained by the lens assembly 1 under the condition that the interval distance between the lens assembly 1 and the photosensitive assembly 2 meets the imaging distance; in addition, the camera module further comprises a sliding mechanism 3 and a power mechanism 4. The sliding mechanism 3 comprises a first moving member 31 and a second moving member 32, the first moving member 31 is movably connected to the second moving member 32 through a guide groove 311 and a guide block 321 which slide relatively, and the lens assembly 1 is arranged on the second moving member 32; the power mechanism 4 is used for driving the first moving member 31 to reciprocate on the motion path, so that the guide block 321 reciprocates in the guide groove 311, and the first moving member 31 drives the lens assembly 1 to approach and depart from the photosensitive assembly 2 on the optical path; the movement path and the optical path have an included angle.

The embodiment of the application provides a camera module, in order to compromise the length and the imaging demand of camera module, adopts the telescopic scheme of camera module 1. Specifically, the first moving member 31 can drive the lens assembly 1 to approach and depart from the photosensitive assembly 2 on the optical path, and when the camera module does not work, the lens assembly 1 can be made to approach the photosensitive assembly 2, so that the distance between the lens assembly 1 and the photosensitive assembly 2 is smaller, the total length of the camera module is also smaller, and the installation of the camera module on the electronic equipment is facilitated; when the camera module works, the lens assembly 1 is far away from the photosensitive assembly 2, the distance between the lens assembly 1 and the photosensitive assembly 2 is large, and the photosensitive assembly 2 can generate an induction signal for imaging based on external environment light obtained by the lens assembly 1. In addition, an included angle is formed between the optical path and the movement path of the first moving member 31, in the process that the power mechanism 4 drives the first moving member 31 to reciprocate on the movement path, two opposite sides in the guide groove 311 sequentially act on corresponding sides of the guide block 321, and the guide block 321 sequentially slides along the opposite sides in the guide groove 311 to slide in opposite directions, so that the lens assembly 1 approaches to and away from the photosensitive assembly 2 on the optical path, and because the included angle is formed between the optical path and the movement path of the first moving member 31, the first moving member 31 occupies no larger additional space on the optical path in the movement process, which is beneficial to further reducing the length of the camera module.

It should be noted that, referring to fig. 2, 3, 4 and 5, the length of the camera module refers to the length of the camera module in the extending direction a of the optical path.

Note that, referring to fig. 2, 3, 4 and 5, the guide block 321 reciprocates in the guide slot 311, and does not direct the guide block 321 to reciprocate along the depth direction of the guide slot 311, and the movement direction of the guide block 321 is in the same plane as the extension direction of the guide slot 311.

It should be noted that, referring to fig. 2, 3, 4 and 5, the first moving member 31 drives the lens assembly 1 to reciprocate along the optical path, which means that the lens assembly 1 is driven by the first moving member 31 to reciprocate. Specifically, during one reciprocation of the guide block 321 along the guide groove 311, opposite sides of the guide groove 311 sequentially act on corresponding sides of the guide block 321 to realize movement of the guide block 321 in two opposite directions with respect to the guide groove 311.

It can be understood that, for the power mechanism 4 to drive the first moving member 31 to reciprocate on the motion path, so that the guide block 321 reciprocates along the guide slot 311, and thus the first moving member 31 drives the lens assembly 1 to reciprocate on the optical path, specifically, the extending direction a of the motion path and the extending direction b of the optical path both have an included angle with the extending direction of the guide slot 311, and the extending direction of the guide slot 311 is parallel to the plane formed by the motion path and the optical path. The extending direction a of the moving path and the extending direction b of the optical path are shown in fig. 2, 3, 4 and 5, which are an embodiment of the present invention. During the movement of the first moving member 31, the second moving member 32 is subjected to a limiting action along the optical path, so that the second moving member 32 does not follow the first moving member 31 to move along the parallel direction of the movement path, but slides along the guide groove 311 relative to the first moving member 31, and the sliding of the second moving member 32 relative to the first moving member 31 and the movement of the first moving member 31 on the movement path are combined, that is, the movement of the second moving member 32 relative to the housing of the electronic device.

It can be appreciated that the embodiment of the present application realizes the expansion and contraction of the lens assembly 1 by the relative sliding of the guide groove 311 and the guide block 321, and the expansion and contraction reliability of the lens assembly 1 is higher. Specifically, the guide groove 311 and the guide block 321 which slide relatively are easy to realize, are convenient to process and install, have simple structure, do not need to be provided with additional parts, and have higher reliability; the extension movement and the retraction movement of the lens assembly 1 are realized by the pushing action of the first moving part 31, so that the movement of the lens assembly 1 is stable and has high reliability; the transmission efficiency of guide slot 311 and guide block 321 is higher, friction loss is lower, the output force of power unit 4 can not produce great loss, even do not set up spare part that is used for increasing the output force of power unit 4 such as reduction gear, the output force of power unit 4 also can satisfy the demand, this is favorable to reducing the structure complexity, improve the reliability of camera module, also be favorable to reducing the energy consumption, moreover, lower friction loss between guide slot 311 and the guide block 321 is favorable to reducing the risk of friction and falling the bits, be favorable to alleviating the problem that the bits fall to optics area and influence photosensitive assembly 2 imaging.

Preferably, referring to fig. 2, 3, 4 and 5, in some embodiments, in order to further reduce friction loss between the guide block 321 and the guide groove 311, a lubricant may be applied between the guide block 321 and the guide groove 311.

The guide groove 311 and the guide block 321 may have various implementation forms, so that the guide groove 311 has two opposite side walls for acting with the guide block 321, and the guide block 321 is disposed between the two side walls. Illustratively, the guide block 321 may be a roller, a bump, or the like, and the shape of the guide groove 311 for two opposite side walls acting on the guide block 321 is not limited, and may be rectangular, circular, elliptical, T-shaped, L-shaped, or irregular, or the like. The guide groove 311 may have an opening 71 at one end in the extending direction, may have openings 71 at both ends in the extending direction, or may have no opening 71 at both ends in the extending direction. The two opposite side walls of the guide groove 311, which are used for acting with the guide block 321, refer to two side walls respectively pressed against the corresponding side surfaces of the guide block 321 during one reciprocation of the guide block 321 along the guide groove 311.

The relative length of the guide groove 311 and the guide block 321 is not limited, and the length of the guide groove 311 may be greater than the length of the guide block 321, or the length of the guide block 321 may be greater than the length of the guide groove 311. Preferably, referring to fig. 2, 3, 4 and 5, one of the guide groove 311 and the guide block 321 is a first sliding structure, and the other is a second sliding structure, the first sliding structure is disposed on the first moving member 31, the second sliding structure is disposed on the second moving member 32, and the length of the first sliding structure is greater than the length of the second sliding structure along the relative sliding direction of the first moving member 31 and the second moving member 32. In such a structural form, the second sliding structure has a smaller length, so that a worker can design the second moving part 32 into a smaller size, the second moving part 32 with a smaller size is beneficial to reducing the space occupied by the second moving part 32 on the optical path, and the camera module has a smaller size. In addition, the smaller size of the second sliding structure is also beneficial to the stress between the first sliding structure and the second sliding structure. On this basis, in some embodiments, the first sliding structure is a guide groove 311.

On the basis that the length of the first sliding structure is greater than that of the second sliding structure, in some alternative embodiments, referring to fig. 2, 3, 4 and 5, the movement path is perpendicular to the optical path, and the distance between the head end and the tail end of the first sliding structure in the extending direction a of the optical path is equal to the imaging distance. It should be noted that, the first sliding structure has a head end and a tail end defined in the following manner, the second sliding structure slides between the head end and the tail end of the first sliding structure, when the second sliding structure is located at the head end of the first sliding structure, the distance between the lens assembly 1 and the photosensitive assembly 2 is minimum, and when the second sliding structure is located at the tail end of the first sliding structure, the distance between the lens assembly 1 and the photosensitive assembly 2 is maximum, and at this time, the photosensitive assembly 2 generates an induction signal for imaging based on the external ambient light obtained by the lens assembly 1. It should be noted that, one of the guide groove 311 and the guide block 321 is a first sliding structure, the other is a second sliding structure, the first sliding structure is disposed on the first moving member 31, the second sliding structure is disposed on the second moving member 32, including the following two cases, in which the guide groove 311 is disposed on the first moving member 31, and the guide block 321 is disposed on the second moving member 32; second, the guide groove 311 is disposed on the second moving member 32, and the guide block 321 is disposed on the first moving member 31.

The limiting effect of the second moving member 32 along the optical path may be implemented in various manners, in some embodiments, the limiting effect of the second moving member 32 along the optical path is provided by a first limiting member, which is relatively fixed to the housing, and extends in a parallel direction of the optical path, and the second moving member 32 is formed with a guide hole corresponding to the first limiting member, and the first limiting member is slidably inserted in the guide hole. On this basis, in some embodiments, the number of the first limiting members is plural, and plural first limiting members are disposed around the lens assembly 1. Preferably, in some embodiments, referring to fig. 2, 3, 4 and 5, the first limiting member is a guide rod.

Generally, in some embodiments, referring to fig. 2, 3, 4, and 5, the motion path is perpendicular to the optical path. Thus, the first moving member 31 occupies a smaller space in the extending direction of the optical path during the moving process, which is beneficial to making the length of the camera module smaller and is more beneficial to the installation of the camera module on the electronic device. On this basis, in some embodiments, in order to further reduce the space occupied by the first moving member 31 in the extending direction of the optical path, the projection profile of the first moving member 31 is located outside the projection profile of the second moving member 32 in the extending direction of the optical path.

In some other embodiments, the motion path and the optical path may not be perpendicular. The non-perpendicularity of the movement path and the optical path may be caused by tolerance, or may be an adjustment made by a worker according to the movement speed of the first moving member 31 and the second moving member 32, the output force of the power mechanism 4, and the relative positions of the lens assembly 1, the photosensitive assembly 2 and the power mechanism 4.

Further, in some alternative embodiments, referring to fig. 2, 3, 4 and 5, one of the guide groove 311 and the guide block 321 is a first sliding structure, the other is a second sliding structure, the first sliding structure is disposed on the first moving member 31, the second sliding structure is disposed on the second moving member 32, the first sliding structure has a driving surface and a guide surface, the driving surface is opposite to the guide surface, the driving surface is used for providing a driving force for driving the second sliding structure to move, and the guide surface is used for limiting the second sliding structure to the driving surface. In this structural form, the driving surface is used for pushing the second moving part 32 to move, and the guiding surface is used for limiting, so that the second moving part 32 is prevented from being impacted by the driving surface and separated from the driving surface, and the stability of the movement of the second moving part 32 is improved. On this basis, in some embodiments, the driving surface and the guiding surface are interchanged once during one reciprocation of the lens assembly 1.

In some other embodiments, it is also possible to have the first sliding structure with only the driving surface and without the guiding surface, i.e. with a distance between the side opposite the driving surface and the second sliding structure. In this way, friction between the first sliding structure and the second sliding structure in the moving process of the second moving member 32 is reduced, and friction area between the first sliding structure and the second sliding structure is also reduced, so that risk of friction and chip removal is reduced. And the friction between the first sliding structure and the second sliding structure is reduced, so that the requirement of the first moving part 31 on the output force of the power mechanism 4 is reduced, the energy consumption is reduced, and the design index of the power mechanism 4 is reduced.

The driving surface and the guiding surface extend along the sliding direction of the guiding block 321 and the guiding slot 311. In addition, the drive surface and the guide surface may be implemented in a variety of ways. Illustratively, in some embodiments, two opposite sides of the first sliding structure in the width direction may be provided, and in other embodiments, two opposite sides of the first sliding structure in the depth direction of the guide groove 311 may be provided, in which case the guide groove 311 has two opposite sides in the depth direction.

In this way, in the case that the co-acting component 5 includes the lens motor 51, the second moving member 32 is configured to drive the lens motor 51 to move, the lens component 1 is disposed on the lens motor 51, and the lens motor 51 can drive the lens component 1 to move along the optical path under the driving action of the second moving member 32. The lens motor 51 has a fine focusing function, the synchronous component 5 is driven by the second moving part 32 to move to realize coarse focusing, and then the lens motor 51 drives the synchronous component to perform fine focusing. Preferably, in some embodiments, the lens motor 51 may be an open loop voice coil motor, a closed loop voice coil motor, an optical anti-shake voice coil motor, or the like. In the case that the co-acting component 5 does not include the lens motor 51, the focusing function of the lens component 1 is completely realized by the driving of the second moving member 32, and the load of the second moving member 32 is relatively low, so that the energy consumption is reduced, and a worker can select between the two schemes according to circumstances. It should be noted that the interlock assembly 5 does not include the lens motor 51, i.e., the camera module does not include the lens motor 51.

In some embodiments, referring to fig. 2, 3, 4 and 5, the camera module further includes a circuit board 9. The circuit board 9 is used to transmit signals to the lens motor 51. The circuit board 9 is fixed to a housing of the electronic device. On this basis, in some embodiments, the lens motor 51 and the circuit board 9 may be connected by a metal spring, and during the movement of the lens motor 51, the metal spring deforms to ensure the electrical connection between the circuit board 9 and the lens motor 51; in other embodiments, the circuit board 9 may be a flexible circuit board 9, and the flexible circuit board 9 is bent or stretched during the reciprocating movement of the lens motor 51.

The optical information from the lens assembly 1 is irradiated onto the photosensitive chip 21 through the optical filter 22, and the photosensitive chip 21 generates a sensing signal and transmits the sensing signal to the circuit board 9. On the basis that the lens motor 51 and the circuit board 9 can be connected by adopting a metal spring, the circuit board 9 and the optical filter support 23 can be electrically connected, and the optical filter support 23 is electrically connected with the lens motor 51 through the metal spring.

In such a structural form, the interlock assembly 5 extends out of the accommodating shell 7 through the opening 71 to meet the imaging distance between the interlock assembly and the photosensitive assembly 2, and the interlock assembly 5 retracts from the accommodating shell 7 to reduce the length of the camera module when the camera module is not in operation. One end of the sealing member 8 is attached to the inner surface of the accommodating case 7, and the other end is attached to the same moving member 5 or the second moving member 32, so that an isolation environment c isolated from the photosensitive member 2 is formed inside the sealing member 8, and the optical path can be prevented from being blocked, and the imaging quality can be improved.

Specifically, the sealing member 8 surrounds the opening 71, and impurities in the external environment enter the housing case 7 from the opening 71, that is, enter the surrounding environment of the sealing member 8, and one end of the sealing member 8 is attached to the inner surface of the housing case 7, and the other end is attached to the moving component 5 or the second moving component 32, so that both ends of the sealing member 8 along the extending direction b of the optical path are sealed, and an isolated environment c isolated from the photosensitive component 2 is formed.

It will be appreciated that referring to fig. 2, 3, 4 and 5, the seal 8 has a cylindrical structure surrounding the interlock assembly 5. The two ends of the tubular structure along the extending direction, namely the two ends along the extending direction of the optical path. The tubular structure surrounding the interlock assembly 5 means that a projection of an inner wall of the tubular structure in the extending direction b of the optical path surrounds the interlock assembly 5.

The inside of the housing 7 refers to a side of the housing 7 away from the external environment. The positions of the power mechanism 4 and the slide mechanism 3 are not limited, and may be inside the housing case 7 or outside the housing case 7.

It should be noted that, the inner wall of the opening 7 may be provided with a sealing rubber ring to achieve the dustproof effect, but in the process of passing through the opening 71, the same moving assembly 5 is easy to rub against the sealing rubber ring, and the chips generated by friction easily block the optical path to affect imaging. In order to avoid larger friction between the same moving assembly 5 and the sealing rubber ring, the contact pressure between the sealing rubber ring and the same moving assembly 5 is not too large, but the sealing effect cannot be ensured. If the lens assembly 1 is dipped with water, the sealing rubber ring cannot completely block the water outside the accommodating shell 7, which easily causes the failure of the module operation. In the embodiment of the present application, the isolation environment c may be configured such that a gap exists between the cam module 5 and the opening 71, and the seal 8 moves along with the cam module 5 during the movement of the cam module 5, with little or no friction between the cam module 5 and the opening 71. The friction factor is not needed to be considered in the two ends of the sealing piece 8 and the sealing connection, the sealing connection is tight, and the waterproof and dustproof effects are good.

Preferably, to avoid the seal 8 obstructing the movement of the co-acting assembly 5, in some embodiments the deformable length of the seal 8 in the optical path is greater than or equal to the distance the co-acting assembly 5 moves in the optical path.

Preferably, referring to fig. 2, 3, 4 and 5, in order to avoid the blocking of the movement of the interlock assembly 5 by the seal 8, in some alternative embodiments, the seal 8 is an elastic member, and the elastic direction of the seal 8 is parallel to the optical path. In this way, the seal 8 has elasticity, so that the seal 8 can power the movement of the second movement element 32 in the optical path. Specifically, if the lens assembly 1 is located near the photosensitive assembly 2, the sealing member 8 is in an elastic stretched state, and the sealing member 8 will exert a certain stretching effect on the co-acting assembly 5 during the movement of the lens assembly 1 in a direction away from the photosensitive assembly 2, which can reduce the requirement of the second moving member 32 for the driving force of the power mechanism 4. If the lens assembly 1 is located at a position away from the photosensitive assembly 2, the sealing member 8 is in an elastic compression state, and the sealing member 8 can play a certain role in pushing the same moving assembly 5 during the movement of the lens assembly 1 in a direction approaching to the photosensitive assembly 2, which can also reduce the requirement of the second moving member 32 for the driving force of the power mechanism 4.

In some alternative embodiments, referring to fig. 2, 3, 4 and 5, the follower assembly 5 is sealingly connected to the second moving member 32, and along the extending direction b of the optical path, the projection profile of the follower assembly 5 is located within the projection profile of the second moving member 32, and the sealing member 8 is supported between the inner surface of the housing shell 7 and the upper surface of the second moving member 32. In this way, the sealing member 8 is supported between the inner surface of the housing case 7 and the upper surface of the second moving member 32, facilitating the assembly of the sealing member 8. The synchronous component 5 is connected with the second moving part 32 in a sealing way, and the isolation environment c is isolated from the photosensitive component 2.

In some alternative embodiments, the sealing member 8 is made of rubber, and the wall surface of the sealing member 8 is provided with folds to meet the requirement of extension and compression of the sealing member 8 along the extending direction b of the optical path.

Preferably, in some alternative embodiments, the power mechanism 4 is disposed within the housing 7, on the basis that the camera module further comprises the housing 7. Of course, in some other embodiments, the power mechanism 4 may be disposed outside the housing case 7 as appropriate. The power mechanism 4 in the embodiment of the present application may be implemented by various ways, for example, the power mechanism 4 may use a power cylinder, a linear motor or a rotating motor 41 to provide power for the first moving member 31, or may be a manual mechanism, that is, a user manually adjusts the power mechanism 4 to control the retraction of the synchronous component 5. Specifically, in some embodiments, referring to fig. 2, 3, 4 and 5, the power mechanism 4 includes a rotating electric machine 41 and a second guide 42. The first moving member 31 is in screw drive connection with the output shaft of the rotating electrical machine 41, the direction of extension of the output shaft of the rotating electrical machine 41 being the same as the direction of extension a of the movement path. The second guide member 42 is fixed relative to the housing of the electronic device, the second guide member 42 extends along an extending direction a of the moving path, the second guide member 42 is slidably connected to the first moving member 31, a relative sliding direction of the second guide member 42 and the first moving member 31 is parallel to the extending direction a of the moving path, and the second guide member 42 is used for preventing the first moving member 31 from rotating along with the output shaft of the rotating motor 41.

The second guide 42 may be implemented in a variety of forms, and in some embodiments, the second guide 42 may be a rod that is threaded onto the second mover 32, for example. In some other embodiments, the second guide 42 is a protrusion formed on the inner wall of the housing case 7 extending in the direction in which the movement path extends, the protrusion being engaged with a groove formed on the first guide 6. In some embodiments, the number of the protrusions and the grooves is multiple, the protrusions are arranged side by side, and the protrusions and the grooves are arranged in a one-to-one correspondence.

In some embodiments, referring to fig. 2, 3, 4 and 5, the power mechanism 4 further includes a support member 43, the support member 43 is relatively fixed with the housing of the electronic device, the output shaft of the rotating motor 41 is disposed through the first moving member 31, and the end of the output shaft of the rotating motor 41 is rotationally connected with the support member 43. In this way, the support 43 can support the end of the output shaft of the rotating electrical machine 41, which is advantageous for improving the stress situation of the output shaft of the rotating electrical machine 41, especially the stress situation of the output shaft of the rotating electrical machine 41 when the second moving member 32 moves to the end of the output shaft of the rotating electrical machine 41.

The foregoing is merely a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and variations may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
