The following describes a camera module 100 according to an embodiment of the present invention with reference to the drawings.

Referring to fig. 1 to 10, a camera module 100 according to an embodiment of the present invention may include: the lens assembly 10, the first optical path changing assembly 30 and the image sensor 40.

Specifically, the first optical path changing assembly 30 is disposed on the outgoing side of the lens group 10, and the light can be reflected by the first optical path changing assembly 30 to change the propagation direction of the light. Here, the lens group 10 may be a short-focus lens, a medium-focus lens, a long-focus lens, or a combination of at least two thereof.

In the related art, in order to achieve a high-magnification zoom function, a complicated lens structure is adopted, so that the length of the camera module is too long, and when the camera module is used for electronic devices such as mobile phones and tablet computers, the camera module needs to occupy a large space (for example, the Z-Z' direction shown in fig. 1) for configuration, which is not beneficial to meeting the size requirement and the component arrangement requirement of the electronic devices.

Therefore, in the present invention, as shown in fig. 1 to 10, the first light path changing assembly 30 includes a first reflecting member 301 and a second reflecting member 302, the first reflecting member 301 has a first reflecting surface 31, and the second reflecting member 302 has two second reflecting surfaces 32a and 32 b. The outgoing light of the lens assembly 10 (e.g. along the direction Z to Z' shown in fig. 1) passes through the first reflective surface 31 and then passes through the two second reflective surfaces 32a and 32b, or the outgoing light of the lens assembly 10 passes through the two second reflective surfaces 32a and 32b and then passes through the first reflective surface 31, both of which can change the propagation direction of the light. Make light carry out the cubic reflection in camera module 100, increased light path length in limited space to reduce the back focal length of lens group 10, improved Z-Z' to space utilization at least, reduced the shared length space of camera module 100, satisfied the demand that reduces whole usage space. Further, the image sensor 40 is disposed on the exit side of the first light path changing member 30.

After exiting from the lens group 10 along the direction Z to Z', the light propagates to the first optical path changing assembly 30, and the light is reflected by the first reflective surface 31 of the first reflective member 301 and the second reflective surfaces 32a and 32b of the second reflective member 302 in sequence, or the light is reflected by the second reflective surfaces 32a and 32b of the second reflective member 302 and the first reflective surface 31 of the first reflective member 301 in sequence, and finally reaches the image sensor 40 for imaging.

According to the utility model discloses camera module 100, light can change the cooperation of first reflection piece 301 and second reflection piece 302 of subassembly 30 through first light path, carries out the cubic reflection and realizes focusing to reduce the burnt length in back of lens group 10, reduced the shared length space of camera module 100, satisfied the demand that reduces whole usage space.

In some embodiments, as shown in fig. 1-5, 9 and 10, the first reflector 301 is configured to redirect the outgoing light rays of the lens set 10 to propagate along a first direction (e.g., along the X-X ' direction shown in fig. 1), and the second reflector 302 is configured to redirect the outgoing light rays of the first reflector 301 (e.g., along the X-X ' direction shown in fig. 1) to propagate along a second direction (e.g., along the X ' X direction shown in fig. 1). In other words, the emergent light of the lens assembly 10 can be reflected by the first reflector 301 and the second reflector 302 in sequence, so as to change the propagation direction of the light, and reduce the length and space occupied by the camera module 100.

In addition, as shown in fig. 1 to 5, 9 and 10, the first direction is perpendicular to the emergent light of the lens group 10, and the second direction is opposite to the first direction, so that the light can be reflected for multiple times to facilitate shortening of the focusing stroke, so that the camera module 100 occupies a smaller space in a three-dimensional space, thereby facilitating size miniaturization of the electronic device and meeting the arrangement requirements of other components.

For example, in the example shown in fig. 1-3, the light travels to the first reflective member 301 along the Z to Z ' direction, and the light is reflected by the first reflective surface 31 of the first reflective member 301 to travel along the X to X ' direction and reach the second reflective member 302, and then the light is reflected by the two second reflective surfaces 32a and 32b of the second reflective member 302 to travel along the X ' to X direction and reach the image sensor 40 for imaging.

In some embodiments, as shown in fig. 6-8, the second reflector 302 is configured to redirect the outgoing light rays of the lens set 10 to propagate in a third direction (e.g., in the Z 'to Z directions shown in fig. 6), and the first reflector 301 is configured to redirect the outgoing light rays of the second reflector 302 (e.g., in the Z' to Z directions shown in fig. 6) to propagate in the second direction. In other words, the emergent light of the lens assembly 10 can be reflected by the second reflector 302 and the first reflector 301 in sequence, so as to change the propagation direction of the light, and reduce the length and space occupied by the camera module 100.

In addition, as shown in fig. 6-8, the third direction is opposite to the outgoing light direction of the lens group 10, and the second direction is perpendicular to the third direction. So that the light can be reflected for multiple times, which is beneficial to shortening the focusing stroke, and the camera module 100 occupies a smaller space in the three-dimensional space, thereby being beneficial to the size miniaturization of the electronic equipment and meeting the arrangement requirements of other components.

For example, in the example shown in fig. 6 to 8, the light travels to the second reflecting member 302 along the Z to Z ' direction, and the light instead travels along the Z ' to Z direction by the secondary reflection of the two second reflecting surfaces 32a and 32b of the second reflecting member 302 and reaches the first reflecting member 301, and then is reflected by the first reflecting surface 31 of the first reflecting member 301 and travels along the X ' to X direction and reaches the image sensor 40 for imaging.

Light propagates in first light path changes subassembly 30, can reduce the shared Z-Z 'of camera module 100 to the space, and can not increase again shared Y-Y' to the space, makes camera module 100 each part arrange more orderly rationally, and production and application in electronic equipment are easier.

In some embodiments, as shown in fig. 1 and fig. 2, the first reflective member 301 may be a triangular prism or a mirror, which can change the direction of light, and has a simple structure and is easy to arrange.

In some embodiments, as shown in fig. 1, 4 and 5, the second reflective member 302 may be a trapezoidal prism (e.g., an isosceles trapezoidal prism), and two side surfaces of the trapezoidal prism are formed as two second reflective surfaces 32a and 32b, so that the change of the light direction can be realized, and the structure is simple and easy to arrange.

In some embodiments, as shown in FIG. 1, the second reflector 302 is a trapezoidal prism. The light reflected by the first reflecting member 301 enters the trapezoidal prism along the X to X ' direction, is changed to propagate along the Z ' to Z direction after being reflected by one of the second reflecting surfaces 32b, and then exits the second reflecting member 302 along the X ' to X direction after being reflected by the other one of the second reflecting surfaces 32a, and reaches the image sensor 40 for imaging.

According to some embodiments of the present invention, as shown in fig. 4 and 5, the second reflector 302 includes two optical elements 33a, 33b, and the optical elements 33a, 33b are triangular prisms (e.g., right trapezoid prisms). Each triangular prism has a second reflecting surface 32a, 32 b. The double-reflection focusing mechanism has the advantages that the double-reflection focusing mechanism can reflect light rays twice, is simple in structure and easy to arrange, is beneficial to shortening focusing stroke, occupies smaller space in a three-dimensional space, is beneficial to size miniaturization of electronic equipment, and meets the arrangement requirements of other components.

In some embodiments, the second reflector 302 includes two optical elements 33a and 33b, the optical elements 33a and 33b are reflectors, each reflector has one second reflective surface 32a and 32b, and can implement two reflections in the light direction, and the structure is simple, the arrangement is easy, and it is beneficial to shorten the focusing stroke, the occupied space of the camera module 100 in the three-dimensional space is smaller, and it is beneficial to miniaturizing the size of the electronic device and meeting the arrangement requirements of other components.

In some embodiments, the second reflector 302 includes two optical elements 33a and 33b, the two optical elements 33a and 33b are a triangular prism and a reflector respectively, the triangular prism and the reflector both have one second reflective surface 32a and 32b, so that two reflections in the light direction can be realized, the structure is simple, the arrangement is easy, the focusing stroke can be shortened, the camera module 100 occupies a smaller space in a three-dimensional space, the size of the electronic device can be miniaturized, and the arrangement requirements of other components can be met.

It should be noted that the light may first enter the triangular prism, and the emergent light of the triangular prism then enters the reflector, or the light may first enter the reflector, and the emergent light of the reflector then enters the triangular prism.

For example, as shown in fig. 4 and 5, the second reflector 302 includes two optical elements 33a and 33 b. The light reflected by the first reflector 301 enters the optical elements 33a and 33b along the X to X ' direction, and after being reflected by the second reflecting surface 32b of one optical element 33b, the light is changed to propagate along the Z ' to Z direction, and then after being reflected by the second reflecting surface 32a of the other optical element 33a, the light exits the second reflector 302 along the X ' to X direction and reaches the image sensor 40 for imaging.

By the diversified arrangement of the second reflecting member 302, the flexibility of the arrangement of the first optical path changing assembly 30 can be increased, and the reliability of the arrangement of the first optical path changing assembly 30 can be improved. Optionally, the material of the reflector or the triangular prism may be glass, plastic, or the like, and may be selected according to design requirements.

In some embodiments, as shown in fig. 1, 2, 4 and 5, the position of the second reflector 302 along the direction of the incident light of the second reflector 302 is adjustable, for example, the position of the trapezoidal prism in fig. 1 along the X-X' direction is adjustable. By adjusting the position focusing of the second reflecting member 302 along the direction of the incident light, if the moving stroke of the second reflecting member 302 is a during focusing, the amount of movement of the back focus is 2 times of the moving stroke, i.e. 2A, so that the focusing stroke of 1/2 can be shortened by the turning of the light path, and the camera module 100 does not need to reserve too large focusing space along the X-X 'direction and the Z-Z' direction, thereby improving the space utilization rate of the camera module 100 in the X-X 'direction and the Z-Z' direction, i.e. improving the space utilization rate of the camera module 100 in the height and length directions.

In some embodiments, as shown in fig. 1, 2, 4 and 5, the position of the first light path changing assembly 30 along the direction of the incident light of the second reflecting member 302 is adjustable. That is, the entire first light path changing assembly 30 moves to perform focusing, so that the 1/2 focusing stroke can be shortened, and the space utilization rate of the camera module 100 in the X-X 'direction and the Z-Z' direction can be improved. For example, in the example shown in fig. 8, the first light path changing member 30 includes a triangular prism and a trapezoidal prism, and the triangular prism and the trapezoidal prism are glued by glue to constitute a unified gluing prism group, and the position of the unified gluing prism group in the Z-Z' direction as a whole is adjustable.

In some embodiments, as shown in fig. 1-10, in a direction perpendicular to an exit light line of the lens group 10, the image sensor 40 and the second reflective surface 32a are located on two sides of the lens group 10 (for example, along the direction of X-X ' shown in fig. 1), or the image sensor 40 and the first reflective surface 31 are located on two sides of the lens group 10, so that the space utilization rate in the direction of X-X ' is effectively improved, compared with the case where the image sensor 40 and the second reflective surface 32a or the image sensor 40 and the first reflective surface 31 are located on the same side of the lens group 10, the optical path length is increased in the limited spatial range in the direction of X-X ', and the size range that can be used for moving focusing is increased, so as to facilitate focusing.

In some embodiments of the present invention, as shown in fig. 10, the lens group 10 includes at least one lens 11a, 11b, 11c, and the position of the at least one lens 11a, 11b, 11c along the optical axis of the lens group 10 is adjustable to perform inner zooming, so that the dustproof sealing performance is good, the manufacturing precision is high, and the focusing effect is better. In some embodiments in which the position of the second reflecting element 302 or the first optical path changing assembly 30 is adjustable, referring to fig. 10, by increasing the adjustment of the lenses 11a, 11b, and 11c, the original moving distance of the focusing stroke of the single second reflecting element 302 or the single first optical path changing assembly 30 can be shared or increased or decreased, so as to achieve a better focusing effect.

For example, in some embodiments, as shown in fig. 10, the lens set 10 may include three lenses 11a, 11b, 11 c. The three lenses 11a, 11b, 11c are stacked along the optical axis direction, wherein the position of one lens 11c can be adjusted along the Z-Z 'direction, and the second reflector 302 can be adjusted along the X-X' direction, so that the moving distance of the focusing stroke is reduced, and the focusing effect is better.

According to some embodiments of the present invention, as shown in fig. 1 and 2, the position of the image sensor 40 along the direction of the emergent light of the first light path changing assembly 30 (e.g., along the X-X' direction shown in fig. 1) is adjustable. The adjustment of the image sensor 40 does not increase the total length of the optical path during the movement and has a characteristic of stabilizing the optical path. In some embodiments in which the position of the second reflecting element 302 or the first optical path changing assembly 30 is adjustable, referring to fig. 1 and fig. 2, by increasing the adjustment to the image sensor 40, the original moving distance of the focusing stroke of the single second reflecting element 302 or the single first optical path changing assembly 30 can be shared or increased or decreased, so as to optimize and improve the requirement of the focusing function, and achieve a better focusing effect.

In some embodiments, the camera module 100 may include a driving component for driving the movement of the component for focusing (e.g., the first optical path changing component 30, the lenses 11a, 11b, 11c, or the image sensor 40), so that the camera module 100 has an Auto-Focus (AF) function. In some embodiments, the drive assembly may include a drive motor. For example, the driving Motor may implement the AF function using a Stepping Motor (SM), a Voice Coil Motor (VCM), a Piezoelectric Motor (PM), etc., and a Micro-electro-mechanical Systems (MEMS) actuator module.

In some embodiments, as shown in fig. 8 and 9, the first reflective member 301 and the second reflective member 302 can be glued by glue, so that the structure is more compact, and under the condition that the total length of the camera module 100 is not changed, the integrated structure can increase the flexibility of moving and focusing in the X-X 'direction and the Z-Z' direction, thereby achieving a better focusing effect. For example, as shown in fig. 8 and 9, the first reflecting member 301 is a triangular prism, the second reflecting member 302 is a trapezoidal prism, and the triangular prism and the trapezoidal prism are glued by a glue to form a one-piece glued prism assembly.

In some embodiments, the camera module 100 further includes a filter 50. The filter 50 may be disposed between the first optical path changing assembly 30 and the image sensor 40 as shown in fig. 1 and 2, or the filter 50 may be disposed between the lens set 10 and the first optical path changing assembly 30 as shown in fig. 3. In the above structure, the optical filter 50 can effectively prevent the strong ultraviolet from invading, so that the image is clearer, and a more real and beautiful picture is restored.

In some embodiments of the present invention, as shown in fig. 1-10, the camera module 100 further includes a second light path changing assembly 20, the second light path changing assembly 20 is disposed at the incident side of the lens group 10, the second light path changing assembly 20 has a third reflective surface 21, the incident light of the camera module 100 can change the light direction through the second light path changing assembly 20, so that the light propagates along the optical axis direction of the lens group 10. For example, in the example shown in fig. 1, the light emitted from the light source propagates along the direction from Y to Y 'to form the incident light of the camera module 100, and after being reflected by the third reflective surface 21 of the second light path changing assembly 20, the light reaches the lens assembly 10 along the optical axis direction of the lens assembly 10, i.e. the direction from Z to Z'. Compared with the traditional vertical type framework in the related art, the utility model discloses a camera module 100 has changed camera module 100's incident light's direction, has reduced required Y-Y 'to space, has satisfied electronic equipment's thickness requirement.

In addition, as shown in fig. 1 to 10, the emergent light direction of the first reflector 301 and the second reflector 302 is perpendicular to the incident light direction of the second light path changing assembly 20, so that the light path length is increased in a limited space, and the structure is compact, so that the length of the camera module 100 along the optical axis direction of the lens group 10 is reduced, and the space of the camera module 100 in the length direction is reduced.

The driving component is used for driving the trapezoidal prism to move along the X-X' direction so as to realize automatic focusing.
