The above can also be understood as: because the light path of light propagation in the camera module includes the reflection route between each speculum, and the reflection number of times of light between the speculum is more, then the light path of light propagation in the camera module is longer to can further shorten the distance between camera lens subassembly 10 and the sensitization chip 20, and then further reduce the volume of whole camera module, and can also guarantee that the focusing performance of camera module is better.

It should be noted that specific values of the first preset included angle are not limited herein, for example: the value of the first predetermined angle may be 45 degrees.

The specific type of the lens assembly 10 is not limited herein, and for example: the lens assembly 10 may be a concave lens sheet or a convex lens sheet, and of course, the lens assembly 10 may also include a concave lens sheet and a convex lens sheet, thus increasing the variety of types of the lens assembly 10.

As an alternative embodiment, referring to fig. 1 to 5, the lens assembly 10 includes at least two imaging lenses 11, and any adjacent two imaging lenses 11 of the at least two imaging lenses 11 are disposed oppositely. Thus, since the lens assembly 10 includes at least two imaging lenses 11, the imaging lenses 11 may be a concave lens or a convex lens, so that the lens assembly 10 has a good imaging effect.

It should be noted that the imaging lens 11 may be a plastic aspheric lens, so that aberration of light can be corrected, imaging on the photosensitive chip 20 is ensured to be clear, and imaging effect is enhanced.

In addition, the lens assembly 10 may further include a lens base or a lens holder, which will not be described herein again.

The photosensitive chip 20 has a photoelectric conversion function, and can process and finally image light reflected by each reflector.

As an alternative embodiment, the light sensing chip 20 is provided with a filter. Therefore, the optical filter can filter partial light in the light, and the imaging effect is improved.

The filter may be an Infrared filter, so that the filter may also filter Infrared light from the light, and the Infrared filter may also be referred to as an Infrared (IR) filter.

As an alternative embodiment, referring to fig. 1 to 5, the camera module further includes a reflective prism 40, and the reflective prism 40 is located at one side of the lens assembly 10. In this way, the reflecting prism 40 may be a right-angle prism, so that an optical path turning effect on the light ray may be achieved, so that the light ray may be incident into the lens assembly 10 in a predetermined direction.

The material and specific shape of the reflecting prism 40 are not limited herein, and examples thereof include: the reflecting prism 40 may be made of glass, and the reflecting prism 40 may be a triangular pyramid or the like.

As an alternative embodiment, referring to fig. 1 to 5, the camera module may further include a housing 12, where the housing 12 includes an accommodating cavity, and each component of the camera module may be accommodated in the accommodating cavity, so as to implement encapsulation of the camera module and protection of each internal device. The material for manufacturing the housing 12 is not limited herein, and for example: and may be made of alloy steel.

It should be noted that at least one of the focusing function and the anti-shake function of the camera module can be realized by adjusting the position of at least a part of the reflecting mirror, and the adjusting of the position of at least a part of the reflecting mirror may include moving the position of at least a part of the reflecting mirror, or the adjusting of the position of at least a part of the reflecting mirror may include rotating the at least a part of the reflecting mirror, so as to realize the anti-shake function.

For example: as an alternative embodiment, at least part of the reflecting mirror is moved to realize the focusing function; or at least part of the reflecting mirror moves or rotates to realize the anti-shake function. Like this, through the removal or the rotation of at least partial speculum position to can realize focusing function or anti-shake function, strengthen the variety of the function of camera module, still strengthen the flexibility that camera module function realized simultaneously.

Wherein, when the position of speculum removed, lead to light to change at the reflection route of speculum in, make the propagation distance of light in the camera module (can understand the light path) also can change, like this, the light path through light changes to can control the camera module and realize focusing the function. In addition, when the position of the reflector moves or the reflector rotates, the position of the light irradiated on the photosensitive chip 20 changes, and then the change of the optical position in the imaging image formed on the photosensitive chip 20 due to shaking can be offset, so that the optical anti-shaking effect is achieved.

Note that focusing may be referred to as Auto Focusing (AF), and anti-shake may also be referred to as Optical Image Stabilization (OIS).

As an alternative embodiment, the at least one set of mirror groups 30 includes a first set of mirror groups 31, the first set of mirror groups 31 includes a first mirror 311 and a second mirror 312, the first mirror 311 is disposed toward the second mirror 312, and light is incident on the photo-sensing chip 20 through the lens assembly 10, the second mirror 312 and the first mirror 311 in sequence;

wherein the first mirror 311 moves between a first position and a second position, and the second mirror 312 moves between a third position and a fourth position, so as to realize a focusing function; alternatively, the first and second electrodes may be,

the first mirror 311 moves between a first position and a second position, or the second mirror 312 moves between a third position and a fourth position, to implement an anti-shake function.

Like this, the mode through the position change of control first speculum 311 and second speculum 312 is different, can easily control the camera module and realize focusing function or anti-shake function for the camera module realizes focusing function or anti-shake function more convenient.

It should be noted that, referring to fig. 1, when the focusing function is implemented, the first reflecting mirror 311 and the second reflecting mirror 312 may move synchronously (i.e. the moving distance and the moving speed may be equal), that is, the first reflecting mirror 311 and the second reflecting mirror 312 may move in opposite directions, respectively, so that the position of the light irradiated onto the photosensitive chip 20 is not changed. For example: a2 in fig. 1 indicates a position before the first mirror 311 is moved, B2 indicates a position after the first mirror 311 is moved, and a1 indicates an optical path of the light before the above-described mirror is moved; a3 denotes a position before the second mirror 312 is moved, B3 denotes a position after the second mirror 312 is moved, and B1 denotes an optical path of light after the above-described mirror is moved.

In addition, when the anti-shake function is implemented, the position change of the first reflecting mirror 311 and the second reflecting mirror 312 may be controlled to be asynchronous, or the position change of only one of the first reflecting mirror 311 and the second reflecting mirror 312 may be controlled, so that the position of the light irradiated onto the photosensitive chip 20 is changed.

For example: when the focusing function is realized, when the first reflecting mirror 311 is at the first position (the position shown as a2 in fig. 1), the second reflecting mirror 312 is at the third position (the position shown as A3 in fig. 1), the distance between the first reflecting mirror 311 and the second reflecting mirror 312 is a first value, and the propagation distance of the light ray in the camera module is a first distance (the distance of the light path shown in fig. a 1); at this time, the first mirror 311 may move to a second position (as shown in B2 in fig. 1) in a certain direction, and at the same time, the second mirror 312 may move to a fourth position (as shown in B3 in fig. 1) in a direction opposite to the above direction, that is, when the first mirror 311 is at the second position, the second mirror 312 is at the fourth position, the distance between the first mirror 311 and the second mirror 312 is the second value, and the light travels a second distance (as shown in the distance of the optical path in fig. B1) in the camera module. Thus, through the change, the propagation distance of the light in the camera module is changed from the first distance to the second distance, and the values of the first distance and the second distance may not be the same, and meanwhile, referring to a1 and B1, the position of the light irradiating the photosensitive chip 20 may not be changed, thereby realizing the focusing function.

In addition, when the anti-shake function is implemented, the position of the light irradiated on the photosensitive chip 20 can be controlled to change only by controlling the position change of the first reflecting mirror 311 and the second reflecting mirror 312 to be asynchronous, or by controlling the position change (for example, position movement or rotation) of one of the first reflecting mirror 311 and the second reflecting mirror 312, so as to implement the anti-shake function.

As an optional implementation manner, the at least one mirror group 30 further includes a second mirror group 32, the second mirror group 32 includes a third mirror 321 and a fourth mirror 322, the fourth mirror 322 is disposed toward the third mirror 321, and light passes through the lens assembly 10, the second mirror 312, the first mirror 311, the fourth mirror 322, and the third mirror 321 in sequence to be incident on the photo sensor chip 20;

wherein the second reflector 312 and the third reflector 321 move between a fifth position and a sixth position to realize a focusing function;

alternatively, the fourth mirror 322 is moved between the seventh position and the eighth position to perform the anti-shake function.

For example: in implementing the focusing function, referring to fig. 2, C2 in fig. 2 represents the position before the second mirror 312 is moved, and C3 represents the position before the third mirror 321 is moved, that is: c2 and C3 may be used together to indicate the fifth position, and C1 indicates the schematic optical path of the light in the camera module before the second mirror 312 and the third mirror 321 move; in fig. 2, D2 represents the position after the second mirror 312 is moved, D3 represents the position after the third mirror 321 is moved, that is: d2 and D3 can be used together to indicate the sixth position, and D1 indicates the schematic optical path of the light in the camera module after the second mirror 312 and the third mirror 321 are moved. As can be seen from fig. 2, the positions of C1 and D1 on the photosensitive chip 20 are the same, but the distances traveled by the optical paths in the camera module are different, so that the focusing function is realized.

In addition, when the anti-shake function is implemented, referring to fig. 3, E1 in fig. 3 shows a schematic diagram of light path propagation of light rays in the camera module before the fourth reflecting mirror 322 moves, and E2 in fig. 3 shows a position (i.e., a seventh position) before the fourth reflecting mirror 322 moves; f1 in fig. 3 shows the light path propagation of the light in the camera module after the fourth mirror 322 moves, and F2 in fig. 3 shows the position (i.e., the eighth position) of the fourth mirror 322 after moving. As can be seen from fig. 3, the positions of E1 and F1 on the photo chip 20 are different, thereby realizing the anti-shake function.

Compared with the method only including the first group of mirror groups 31, the second group of mirror groups 32 is added in the embodiment of the present invention, and the second group of mirror groups 32 includes the third mirror 321 and the fourth mirror 322, so that, by using a control principle similar to that of the first group of mirror groups 31, the embodiment of the present invention only needs to control the position movement of the second mirror 312 and the third mirror 321, and the focusing function can be realized; meanwhile, the anti-shake function can be realized only by controlling the position of the fourth reflector 322 to move.

In the embodiment of the present application, the second group of reflector sets 32 is further included, so that the light path of light in the camera module can be further extended, and the focusing performance of the camera module can be further enhanced (specifically, refer to corresponding expressions in the third group of reflector sets). In addition, the second group of reflector group 32 is added, so that the focusing function and the anti-shake function of the camera module can be realized more conveniently.

It should be noted that the second group of mirror groups 32 can also be implemented by controlling the movement or rotation of the other mirror positions (for example, the movement or rotation of the fourth mirror 322) when implementing the focusing function and the anti-shake function, and the above-mentioned manner is only an exemplary illustration.

As an alternative embodiment, the second reflector 312 and the third reflector 321 are fixedly connected and form a second preset angle. Thus, since the second reflector 312 and the third reflector 321 are fixedly connected, it is more convenient to control the movement of the second reflector 312 and the third reflector 321.

In addition, the second reflector 312 and the third reflector 321 may be integrally formed, so that the connection strength between the second reflector 312 and the third reflector 321 may be enhanced, and the service life may be prolonged.

The specific value of the second preset angle is not limited herein, for example: the second preset angle may be 135 degrees.

As an alternative embodiment, the first reflector 311 and the fourth reflector 322 are symmetrically distributed about a first direction, and the second reflector 312 and the third reflector 321 are symmetrically distributed about the first direction, where the first direction is a direction in which light is irradiated from the lens assembly 10 to the second reflector 312 (for example, see fig. 2 and 3, a direction in which light is irradiated from the lens assembly 10 to the second reflector 312). Thus, with the above arrangement, the reflection effect of the light between the respective mirrors can be better, and the reflection loss (i.e. the reflection loss can refer to the light that is not finally incident on the photo chip 20) caused by the reflection of the light between the respective mirrors can be reduced.

When the first direction coincides with the horizontal direction, the first direction may also be referred to as a horizontal direction, and the second direction perpendicular to the first direction may be referred to as a vertical direction or a vertical direction.

For example: when the first direction is a horizontal direction, an angle between the first reflecting mirror 311 and the first direction may be 22.5 degrees, an angle between the second reflecting mirror 312 and the second direction may be 22.5 degrees, and an angle between the first reflecting mirror 311 and the second reflecting mirror 312 may be 45 degrees. The setting angles of the third reflector 321 and the fourth reflector 322 can be referred to the setting angles of the first reflector 311 and the second reflector 312, and are not described herein again in detail.

As an alternative embodiment, referring to fig. 4, the at least one mirror group 30 further includes a third mirror group 33, the third mirror group 33 includes a fifth mirror 331 and a sixth mirror 332, the sixth mirror 332 is disposed toward the fifth mirror 331, and light sequentially passes through the lens assembly 10, the second mirror 312, the first mirror 311, the fourth mirror 322, the third mirror 321, the sixth mirror 332 and the fifth mirror 331 and is incident on the photosensitive chip 20;

wherein the second reflector 312 and the third reflector 321 move between a fifth position and a sixth position, and/or the fourth reflector 322 and the fifth reflector 331 move between a ninth position and a tenth position, so as to realize a focusing function;

alternatively, the sixth reflecting mirror 332 is moved between the eleventh position and the twelfth position to implement the anti-shake function.

For example: in order to realize the focusing function, referring to fig. 4, G1 in fig. 4 is used to show the schematic diagram of the light path propagation of the light in the camera module before the second mirror 312, the third mirror 321, the fourth mirror 322 and the fifth mirror 331 move, G2 in fig. 4 is used to show the position before the second mirror 312 and the third mirror 321 move (i.e. the fifth position), and G3 in fig. 4 is used to show the position before the fourth mirror 322 and the fifth mirror 331 move (i.e. the ninth position); h1 in fig. 4 is used to show the schematic optical path propagation of the light in the camera module after the second mirror 312, the third mirror 321, the fourth mirror 322 and the fifth mirror 331 are moved, H2 in fig. 4 is used to show the position after the second mirror 312 and the third mirror 321 are moved (i.e. the sixth position), and H3 in fig. 4 is used to show the position after the fourth mirror 322 and the fifth mirror 331 are moved (i.e. the tenth position). As can be seen from fig. 4, the positions of G1 and H1 on the photosensitive chip 20 are the same, but the distances traveled by the optical paths in the camera module are different, thereby realizing the focusing function.

In addition, when the anti-shake function is implemented, J1 in fig. 5 is used to show the schematic optical path propagation diagram of the light in the camera module before the sixth reflecting mirror 332 moves, and J2 in fig. 5 is used to show the position (i.e., the eleventh position) before the sixth reflecting mirror 332 moves; the reference numeral K1 in fig. 5 is used to show the optical path propagation of the light in the camera module after the sixth mirror 332 moves, and the reference numeral K2 in fig. 5 is used to show the position (i.e., the twelfth position) after the sixth mirror 332 moves. As can be seen from fig. 5, J1 and K1 are irradiated onto the photo chip 20 at different positions, thereby realizing the anti-shake function.

Compared with the manner including the first group of mirror groups 31 and the second group of mirror groups 32, the third group of mirror groups 33 is added in the embodiment of the present application, and the third group of mirror groups 33 includes the fifth mirror 331 and the sixth mirror 332, so that, by using a control principle similar to that of the first group of mirror groups 31 and the second group of mirror groups 312, the embodiment only needs to control the position movement of the second mirror 312 and the third mirror 321, and the position movement of the fourth mirror 322 and the fifth mirror 331, so as to implement the focusing function; meanwhile, the anti-shake function can be realized only by controlling the position of the sixth reflector 332 to move.

In the embodiment of the present application, the third group of reflectors 33 is further included, so that the light path of light in the camera module can be further extended, and the focusing performance of the camera module can be further enhanced. In addition, the third group of reflectors 33 is added, so that the focusing function and the anti-shake function of the camera module can be realized more conveniently.

In addition, the longer the optical path in the camera module, the larger the focusing multiple of the camera module is. For example: when only the first group of reflector set 31 is included, the Back Focal Length (BFL) of the camera module is increased, and the equivalent focal length of the camera module can be increased, so that the focusing multiple of the camera module can be 10 times; when the first group of reflector set 31 and the second group of reflector set 32 are included, the Back Focal Length (BFL) of the camera module is increased, so that the total lens length (TTL) of the camera module can reach more than 40mm, the equivalent focal length (which can also be called as an effective focal length) of the camera module can reach 375mm, and the focusing multiple of the camera module can be 15 times; when the first, second, and third reflecting

mirror groups

31, 32, and 33 are included, the Back Focal Length (BFL) of the camera module increases, so that the total lens length (TTL) of the camera module can reach over 58mm, and the equivalent focal length (also referred to as an effective focal length) of the camera module can reach 500mm, thereby making the focusing multiple of the camera module be 20 times.

It should be noted that the third group of mirrors 33 can also be implemented by controlling the movement or rotation of the other mirrors (for example, the movement or rotation of the fifth mirror 331) when implementing the focusing function and the anti-shake function, and the above-mentioned manner is only an exemplary illustration.

As an alternative embodiment, the fourth reflecting mirror 322 and the fifth reflecting mirror 331 are fixedly connected to form a third preset included angle. In this way, since the fourth mirror 322 and the fifth mirror 331 are fixedly connected, it is more convenient to control the movement of the fourth mirror 322 and the fifth mirror 331.

In addition, the fourth reflecting mirror 322 and the fifth reflecting mirror 331 may be integrally formed, so that the coupling strength between the fourth reflecting mirror 322 and the fifth reflecting mirror 331 may be enhanced, and the service life may be prolonged.

In addition, specific values of the third preset included angle are not limited herein, for example: the third predetermined included angle may be 135 degrees.

It should be noted that, as an optional implementation manner, values of the second preset included angle and the third preset included angle may be the same, so that reflection of light on the reflector may be better achieved. In addition, the reflecting mirror mentioned in the above embodiments may be any one of the first reflecting mirror 311, the second reflecting mirror 312, the third reflecting mirror 321, the fourth reflecting mirror 322, the fifth reflecting mirror 331, and the sixth reflecting mirror 332.

As an alternative implementation manner, the third reflector 321 and the sixth reflector 332 are symmetrically distributed about a second direction, and the fourth reflector 322 and the fifth reflector 331 are symmetrically distributed about the second direction, where the second direction is perpendicular to the first direction, and the first direction is a direction in which light is irradiated to the second reflector by the lens assembly.

Thus, with the above arrangement, the reflection effect of the light between the respective mirrors can be improved, and the reflection loss caused when the light is reflected between the respective mirrors (i.e. the reflection loss can refer to the light which is not finally incident on the photo chip 20) is reduced.

It should be noted that, in the embodiments of the present application, at least some of the mirrors may be provided with a driving member, and the driving member may be configured to drive the corresponding mirror to move or rotate. And above-mentioned driving piece can be voice coil motor, and above-mentioned driving piece can multiplex voice coil motor promptly to use cost has been reduced, the volume of camera module has been reduced.

The embodiment of the present application further provides an electronic device, where the electronic device includes the camera module in the above embodiment, and the electronic device includes the camera module in the above embodiment, so that the electronic device has the same beneficial technical effects as the above embodiment, and the structure of the camera module may refer to the corresponding expressions in the above embodiment, which is not described herein again specifically.
