[0002] At present, electronic equipment (for example, mobile phones, tablet computers and the like) is increasingly popular in people's daily life. In order to meet various shooting requirements, the electronic equipment is usually configured with multiple camera modules. Among them, the configuration of more camera modules will lead to higher cost of the electronic equipment, so that the selling price of the electronic equipment is always high. How to reduce the manufacturing cost of the electronic equipment is a technical problem that the manufacturer urgently needs to solve. SUMMARY

[0006] The first lens, the second lens, the photosensitive chip and the first reflecting element are arranged in the shell, and the first reflecting element can be switched between a first position and a second position,

[0007] When the first reflecting element is located at the first position, the light exit surface of the first reflecting element is staggered with the photosensitive chip, and the second lens is opposite to the photosensitive chip, so that the light passing through the second lens is projected onto the photosensitive chip.

[0008] When the first reflecting element is located at the second position, the light exit surface of the first reflecting element is opposite to the photosensitive chip, so that the light passing through the first lens is reflected by the first reflecting element and then projected onto the photosensitive chip.

[0011] The camera module disclosed by the embodiment of the present application improves the structure of the camera module related to the prior art, and the first reflecting element can be switched between the first position and the second position. When the first reflecting element is located at the first position, the light exit surface of the first reflecting element is offset from the photosensitive chip, and the second lens is opposite to the photosensitive chip, so that the light passing through the second lens is projected on the photosensitive chip, and the light emitted from the first lens is prevented from being reflected by the first reflecting element to the photosensitive surface of the photosensitive chip, thereby realizing image shooting through the second lens. When the first reflecting element is located at the second position, the light exit surface of the first reflecting element is opposite to the photosensitive chip, so that the light passing through the first lens is projected on the photosensitive chip after being reflected by the first reflecting element, and the light emitted from the second lens is prevented from being projected on the photosensitive surface of the photosensitive chip, thereby realizing image shooting through the first lens. In this structure, the photosensitive chip used when the first lens or the second lens shoots an image is the same photosensitive chip, so that the first lens and the second lens can share one photosensitive chip to realize imaging, thereby saving the photosensitive chip, and further reducing the number of photosensitive chips in the electronic device configured with multiple camera modules, which is beneficial to reducing the manufacturing cost of the electronic device.

[0033] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in connection with the specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0034] The technical solutions disclosed by the various embodiments of the present application will be described in detail below in connection with the drawings.

[0035] Please refer to Figures 1 to 7 The present application discloses a camera module, which comprises a shell 100, a first lens 200, a second lens 300, a photosensitive chip 400 and a first reflecting member 500.

[0036] The shell 100 is the basic component of the camera module, which is used to provide a mounting basis for other components of the camera module. The first lens 200, the second lens 300, the photosensitive chip 400 and the first reflecting member 500 are all arranged in the shell 100. In addition, the shell 100 is also used to form some functional spaces or structures, such as the first light transmission port 120 and the second light transmission port 130 described below.

[0037] The first lens 200, the second lens 300 and the photosensitive chip 400 are the core components for realizing imaging in the camera module, and the first reflecting member 500 is the core component for realizing that the first lens 200 and the second lens 300 share the same photosensitive chip 400. In addition, the first reflecting member 500 can be switched between the first position and the second position, so as to enable the camera module to shoot images through the first lens 200 or the second lens 300 by switching the position of the first reflecting member 500.

[0038] In the specific working process, when the first reflecting member 500 is located at the first position, the light exit surface of the first reflecting member 500 is misaligned with the photosensitive chip 400, so that the first lens 200 is misaligned with the photosensitive chip 400, to avoid that the light emitted from the first lens 200 is reflected to the photosensitive surface of the photosensitive chip 400 by the first reflecting member 500. At the same time, the second lens 300 is opposite to the photosensitive chip 400, so that the light passing through the second lens 300 is projected on the photosensitive chip 400. The photosensitive surface of the photosensitive chip 400 receives the light signal, so that the photosensitive chip 400 converts the light signal into an electric signal, thereby realizing imaging. In this case, the camera module shoots images through the second lens 300.

[0039] In a case where the first reflecting member 500 is located at the second position, the light exit surface of the first reflecting member 500 is opposite to the photosensitive chip 400, and of course, the light entrance surface of the first reflecting member 500 can be opposite to the first lens 200, so that the light rays passing through the first lens 200 are reflected by the first reflecting member 500 and then projected onto the photosensitive surface of the photosensitive chip 400. In this case, the light rays passing through the first lens 200 enter the first reflecting member 500 through the light entrance surface of the first reflecting member 500, and then are reflected by the first reflecting member 500 and exit from the light exit surface of the first reflecting member 500 to project onto the photosensitive surface of the photosensitive chip 400, that is, the light rays passing through the first lens 200 are indirectly projected onto the photosensitive surface of the photosensitive chip 400 through the first reflecting member 500, and the photosensitive chip 400 is used to convert the optical signal into an electrical signal to realize imaging. That is, in this case, the camera module captures an image through the first lens 200.

[0040] The camera module disclosed by the embodiment of the present application improves the structure of the camera module related to the prior art, and the first reflecting member 500 can be switched between the first position and the second position. In a case where the first reflecting member 500 is located at the first position, the light exit surface of the first reflecting member 500 is staggered with the photosensitive chip 400, and the second lens 300 is opposite to the photosensitive chip 400, so that the light rays passing through the second lens 300 are projected onto the photosensitive chip 400, and the light rays emitted from the first lens 200 are prevented from being reflected by the first reflecting member 500 to the photosensitive surface of the photosensitive chip 400, thereby realizing image capturing through the second lens 300. In a case where the first reflecting member 500 is located at the second position, the light exit surface of the first reflecting member 500 is opposite to the photosensitive chip 400, so that the light rays passing through the first lens 200 are reflected by the first reflecting member 500 and then projected onto the photosensitive chip 400, and the light rays emitted from the second lens 300 are prevented from being projected onto the photosensitive surface of the photosensitive chip 400, thereby realizing image capturing through the first lens 200.

[0041] In this structure, the photosensitive chip 400 used by the first lens 200 or the second lens 300 for imaging is the same photosensitive chip 400, so that the first lens 200 and the second lens 300 can share one photosensitive chip 400 for imaging, thereby saving the photosensitive chip 400, and further reducing the number of photosensitive chips 400 in the electronic device configured with multiple camera modules, which is conducive to reducing the manufacturing cost of the electronic device. At the same time, the photosensitive chip 400 used by the first lens 200 or the second lens 300 for imaging is the same photosensitive chip 400, so that the images captured by the first lens 200 or the second lens 300 have the same color, and the image captured when switching from the first lens 200 to the second lens 300 is prevented from being side-biased.

[0042] In addition, since the first lens 200 and the second lens 300 are arranged in the same camera module, the distance between the first lens 200 and the second lens 300 is shorter than that when the first lens 200 and the second lens 300 are arranged in different camera modules, thereby reducing the obvious offset of the image taken when switching from the first lens 200 to the second lens 300, and further improving the user experience. At the same time, the first lens 200 and the second lens 300 are arranged in the same camera module, which facilitates the installation of the camera module in the electronic device and simplifies the assembly.

[0043] In a further technical solution, the first lens 200 and the second lens 300 can be arranged on opposite sides of the first reflecting member 500, i.e., the first reflecting member 500 is arranged between the first lens 200 and the second lens 300, and the second lens 300 is rotatably connected to the housing 100, so that the position relationship between the second lens 300 and the photosensitive chip 400 can be adjusted by rotating the second lens 300.

[0044] In a specific working process, when the first reflecting member 500 is located at the first position, the second lens 300 can be overlapped with the photosensitive chip 400, so that the second lens 300 is opposite to the photosensitive surface of the photosensitive chip 400, thereby making the light passing through the second lens 300 project on the photosensitive surface of the photosensitive chip 400, and the photosensitive chip 400 can convert the optical signal into an electrical signal to realize imaging, so as to realize image shooting through the second lens 300.

[0045] When the first reflecting member 500 is located at the second position, the second lens 300 can be rotated to move away from the photosensitive surface of the photosensitive chip 400, so as to avoid the light emitted from the second lens 300 from projecting on the photosensitive chip 400. At the same time, the light exit surface of the first reflecting member 500 can be opposite to the photosensitive chip 400, and of course, the light entrance surface of the first reflecting member 500 can be opposite to the first lens 200, so that the light passing through the first lens 200 is emitted into the first reflecting member 500 through the light entrance surface of the first reflecting member 500, and then is reflected by the first reflecting member 500 to be emitted from the light exit surface of the first reflecting member 500 to project on the photosensitive surface of the photosensitive chip 400. The photosensitive chip 400 can convert the optical signal into an electrical signal to realize imaging, so as to realize image shooting through the first lens 200.

[0046] This structure can move the second lens 300 away from or close to the photosensitive surface of the photosensitive chip 400 by rotating the second lens 300, thereby saving the space required for moving the second lens 300, reducing the size of the camera module, and facilitating the subsequent resetting of the second lens 300 to the position opposite to the photosensitive chip 400.

[0047] In one embodiment, the side of the second lens 300 facing away from the first reflecting element 500 can be rotatably connected with the housing 100, so that the side of the second lens 300 opposite to the first reflecting element 500 can rotate around the side of the second lens 300 opposite to the first reflecting element 500.

[0048] In the specific working process, during the movement of the first reflecting element 500 from the first position to the second position, the first reflecting element 500 can be inserted between the second lens 300 and the photosensitive chip 400, so that the second lens 300 is away from the photosensitive surface of the photosensitive chip 400, and the first reflecting element 500 can push the second lens 300 to rotate, so that the first reflecting element 500 and the second lens 300 can better cooperate, and an additional driving mechanism is avoided to drive the second lens 300 to rotate.

[0049] In addition, when the first reflecting element 500 is located at the first position, the side of the second lens 300 opposite to the first reflecting element 500 can be close to the photosensitive chip 400, so that the second lens 300 and the photosensitive chip 400 are stacked, and the second lens 300 is opposite to the photosensitive surface of the photosensitive chip 400, so that the light passing through the second lens 300 can be projected on the photosensitive surface of the photosensitive chip 400, and the photosensitive chip 400 can convert the optical signal into an electrical signal to realize imaging, so as to realize the shooting of the image through the second lens 300.

[0050] When the first reflecting element 500 is located at the second position, the first reflecting element 500 can be inserted between the second lens 300 and the photosensitive chip 400, and the side of the second lens 300 opposite to the first reflecting element 500 can be pushed by the first reflecting element 500 to rotate away from the photosensitive chip 400, so that the second lens 300 is away from the photosensitive surface of the photosensitive chip 400, and the light passing through the second lens 300 is avoided to be projected on the photosensitive chip 400.

[0051] At the same time, the light exit surface of the first reflecting element 500 can be opposite to the photosensitive chip 400, and the light entrance surface of the first reflecting element 500 can be opposite to the first lens 200, so that the light passing through the first lens 200 can enter the first reflecting element 500 through the light entrance surface of the first reflecting element 500, and then be reflected from the light exit surface of the first reflecting element 500 to be projected on the photosensitive surface of the photosensitive chip 400, and the photosensitive chip 400 can convert the optical signal into an electrical signal to realize imaging, so as to realize the shooting of the image through the first lens 200.

[0052] In this structure, the second lens 300 can be away from or close to the light receiving surface of the light receiving chip 400 by rotating the second lens 300, and when the first reflecting element 500 is in the first position, the second lens 300 can be stacked on the first reflecting element 500, so that the structure between the first reflecting element 500 and the second lens 300 is more compact, thereby saving space and facilitating the reduction of the size of the camera module, and also making it easier for the second lens 300 to be subsequently reset to the position opposite the light receiving chip 400.

[0053] Of course, in other embodiments, the second lens 300 can be connected with the first reflecting element 500, so as to move with the first reflecting element 500 relative to the housing 100, thereby achieving switching between the first position and the second position. Of course, this connection mode of the second lens 300 can also achieve the purpose of the present application, but in this case, the second lens 300 will not rotate relative to the housing 100, but will move relative to the housing 100 within the housing 100, which is more likely to occupy a larger space within the housing 100 and is not conducive to the miniaturization design of the camera module.

[0054] In a feasible technical solution, the camera module can further include a bracket 600, which can be fixed in the housing 100 and can be covered on the light receiving chip 400, thereby being able to play a role in protecting the light receiving chip 400, avoiding the situation that the first reflecting element 500 and the second lens 300 collide or wear the light receiving chip 400, causing the light receiving chip 400 to malfunction, and at the same time, the bracket 600 also provides a mounting basis for the second lens 300, thereby enabling the second lens 300 to be erected on the light receiving chip 400.

[0055] The second lens 300 can be provided on the bracket 600, and the side of the second lens 300 opposite the first reflecting element 500 can be rotatably connected to the bracket 600, so that the bracket 600 can provide a mounting basis for the second lens 300, enabling the second lens 300 to be indirectly connected with the housing 100 through the bracket 600, and of course, the second lens 300 can also be directly connected with the housing 100. At the same time, the bracket 600 can be provided with a light avoiding hole 610, which can be opposite the light receiving chip 400, so that the light emitted from the second lens 300 or the light reflected by the first reflecting element 500 can pass through the light avoiding hole 610 and be projected onto the light receiving chip 400.

[0056] In the specific working process, when the first reflecting member 500 is located at the first position, the side of the second lens 300 close to the first reflecting member 500 can be supported on the bracket 600, so that the second lens 300 is supported on the bracket 600 and opposite to the photosensitive chip 400. In this case, the light avoiding hole 610 is opposite to the second lens 300, so that the light passing through the second lens 300 can pass through the light avoiding hole 610 and be projected on the photosensitive chip 400, and the photosensitive chip 400 converts the optical signal into an electrical signal to realize imaging, so as to realize the shooting of the image through the second lens 300.

[0057] When the first reflecting member 500 is located at the second position, the side of the second lens 300 close to the first reflecting member 500 can be away from the bracket 600, and the first reflecting member 500 can be inserted between the side of the second lens 300 close to the first reflecting member 500 and the photosensitive chip 400. In this case, the first reflecting member 500 is located between the bracket 600 and the second lens 300, so that the second lens 300 is away from the photosensitive chip 400, and the light exit surface of the first reflecting member 500 is opposite to the photosensitive surface of the photosensitive chip 400. Of course, the light entrance surface of the first reflecting member 500 can be opposite to the first lens 200, and the light exit surface of the first reflecting member 500 can also be opposite to the light avoiding hole 610, so that the light emitted through the first lens 200 can pass through the light avoiding hole 610 and be projected on the photosensitive chip 400 after being reflected by the first reflecting member 500, and the photosensitive chip 400 can convert the optical signal into an electrical signal to realize imaging, so as to realize the shooting of the image through the first lens 200.

[0058] In a further technical solution, the camera module can further include a filter 1200, the filter 1200 can be provided with a light avoiding hole 610 and can be opposite to the photosensitive chip 400, and the photosensitive chip 400 can be located between the filter 1200 and the shell 100, so that the light passing through the second lens 300 or the light reflected by the first reflecting member 500 can pass through the filter 1200 and be projected on the photosensitive chip 400. In this structure, the filter 1200 can filter the unnecessary part of the light (such as red light) reflected by the first reflecting member 500 to the photosensitive chip 400 or projected from the second lens 300 to the photosensitive chip 400, so that the part of the light of a specific wavelength reflected by the first reflecting member 500 or emitted from the second lens 300 which is not needed by the camera module does not pass through the filter 1200, so that the light of other wavelengths reflected by the first reflecting member 500 or passing through the second lens 300 can pass through the filter 1200 and be projected on the photosensitive chip 400 to realize imaging, thereby facilitating the improvement of the imaging quality.

[0059] In addition, in the structure, the filter 1200 used by the first lens 200 or the second lens 300 when imaging is the same filter 1200, so that the first lens 200 and the second lens 300 can share one filter 1200 for imaging, thereby saving the filter 1200, and further reducing the number of filters 1200 in the electronic device configured with multiple camera modules, which is conducive to further reducing the cost of the electronic device.

[0060] In an optional technical solution, the camera module can further include a circuit board 1000, the circuit board 1000 can be fixed to the shell 100, the photosensitive chip 400 can be fixed to the circuit board 1000 and can be electrically connected with the circuit board 1000, and the support 600 can be fixed to the circuit board 1000 or the shell 100. In this structure, the circuit board 1000 can provide a mounting basis for the photosensitive chip 400 and also realize electrical conduction of the photosensitive chip 400, so that the circuit board 1000 can play a dual-purpose role, thereby fully utilizing the circuit board 1000. In addition, the circuit board 1000 is conducive to simplifying the circuit and avoiding the use of connecting wires to cause the circuit to be too complex. Specifically, the circuit board 1000 can be a printed circuit board or a soft and hard combined circuit board, and the embodiments of the present application do not limit this.

[0061] In a feasible embodiment, the second lens 300 can be provided with a first magnetic member 710, and the support 600 can be provided with a second magnetic member 720. Wherein, when the first reflecting member 500 is located at the first position, the first magnetic member 710 can be magnetically attracted to the second magnetic member 720, so that the light exit surface of the second lens 300 can be opposite to the photosensitive chip 400, and the second lens 300 can be fixed by magnetic attraction between the first magnetic member 710 and the second magnetic member 720, so that the second lens 300 can be stably and reliably supported on the support 600, reducing the risk that the second lens 300 is easily rotated by external force to affect the imaging quality.

[0062] Optionally, when the first reflecting member 500 is located at the second position, the first magnetic member 710 can repel the second magnetic member 720. In this case, the first magnetic member 710 and the second magnetic member 720 repel each other, so that the side of the second lens 300 away from the first reflecting member 500 is more easily separated from the support 600, which can reduce the resistance when the first reflecting member 500 is inserted between the second lens 300 and the support 600, thereby making it easier for the first reflecting member 500 to move to the second position. Specifically, one of the first magnetic member 710 and the second magnetic member 720 can be an electromagnet, and correspondingly, the other of the first magnetic member 710 and the second magnetic member 720 can be a magnet.

[0063] In a further technical solution, the side of the bracket 600 close to the first reflecting member 500 can have a first guide slope 620, and the bracket 600 can have a second support surface 630, and the first guide slope 620 can be connected with the second support surface 630, so as to guide the first reflecting member 500 to move to the second support surface 630 through the first guide slope 620, thereby avoiding hindering the movement of the first reflecting member 500.

[0064] In the process of moving the first reflecting member 500 from the first position to the second position, the first reflecting member 500 moves along the first guide slope 620, so as to be inserted between the second lens 300 and the bracket 600, so as to separate the second lens 300 and the photosensitive chip 400, and the first reflecting member 500 moves to the second position above the second support surface 630 through the first guide slope 620.

[0065] Specifically, in the case that the first reflecting member 500 is located at the second position, the first reflecting member 500 can be supported on the second support surface 630, of course, the first reflecting member 500 can also not be supported on the second support surface 630, but be supported on the first support surface 110 described below, for example, be supported on the first support surface 110 through the first rolling body 1110 described below, in which case, the first reflecting member 500 can not be in contact with the second support surface 630.

[0066] In a further technical solution, the housing 100 can have a first support surface 110, and the first support surface 110 can be located below the second support surface 630, and in the case that the first reflecting member 500 is located at the first position, the first reflecting member 500 can be supported above the first support surface 110. The first support surface 110 can be provided with a first track 111, and the first reflecting member 500 can be switched between the first position and the second position through the first rolling body 1110 in rolling cooperation with the first track 111.

[0067] In this structure, the first reflecting member 500 is in rolling cooperation with the first support surface 110 through the first rolling body 1110, so that the first reflecting member 500 and the first support surface 110 have smaller friction therebetween, so that the first reflecting member 500 can be more easily and smoothly switched between the first position and the second position, and at the same time, the abrasion of the first reflecting member 500 and the first support surface 110 can be reduced, thereby being beneficial to prolong the service life of the first reflecting member 500 and the first support surface 110.

[0068] Optionally, the first rolling body 1110 can be partially embedded in the first reflecting member 500, so that the first rolling body 1110 can be connected with the first reflecting member 500 in rolling manner, and can guide the movement of the first reflecting member 500 through the cooperation between the first rolling body 1110 and the first track 111, so as to avoid the deviation of the first reflecting member 500 when switching between the first position and the second position, and affect the imaging quality.

[0069] Of course, the first reflecting member 500 can be provided with a second guide slope 510 to guide the movement of the side of the second lens 300 opposite to the first reflecting member 500 on the second guide slope 510, so as to facilitate the movement of the first reflecting member 500 to the second lens 300 and the support 600.

[0070] Meanwhile, the second guide slope 510 can be provided with a second track 511, and in the process of moving the first reflecting member 500 from the first position to the second position, the first reflecting member 500 can be moved relative to the second lens 300 through the second rolling body 1120 cooperating with the second track 511, so as to push the second lens 300 to rotate. In this structure, the second lens 300 is rollingly connected with the first reflecting member 500 through the second rolling body 1120, so that the second lens 300 and the first reflecting member 500 have small friction therebetween, which further facilitates the movement of the first reflecting member 500 to the second lens 300 and the support 600, so that the first reflecting member 500 can be more easily and smoothly moved to the second position. In addition, this structure can avoid the abrasion of the second lens 300 and the first reflecting member 500 as much as possible, so as to prolong the service life of the second lens 300 and the first reflecting member 500.

[0071] Optionally, the second rolling body 1120 can be partially embedded in the side of the second lens 300 opposite to the first reflecting member 500, so that the second rolling body 1120 is connected with the second lens 300 in rotating manner, and can avoid the deviation of the first reflecting member 500 in the movement process through the cooperation between the second track 511 and the second rolling body 1120, so as to affect the imaging quality.

[0072] The first track 111, the second track 511, the first rolling body 1110 and the second rolling body 1120 can be multiple, the multiple first rolling bodies 1110 can be respectively in rolling cooperation with the multiple first tracks 111, the multiple second rolling bodies 1120 can be respectively in rolling cooperation with the multiple second tracks 511, of course, each first track 111 and each second track 511 can be respectively in rolling cooperation with part of the multiple first rolling bodies 1110 and part of the multiple second rolling bodies 1120, so that the cooperation between the first reflecting member 500 and the first support surface 110 and the cooperation between the second lens 300 and the first reflecting member 500 are more stable. Specifically, the first rolling body 1110 and the second rolling body 1120 can be a ball or a roller, and the embodiments of the present application do not limit this.

[0073] In the embodiments of the present application, the first reflecting member 500 can be a triangular prism, the inclined surface of the triangular prism can be the second guide inclined surface 510, and the two right-angled surfaces of the triangular prism can be the light entrance surface and the light exit surface respectively. The light entrance surface can be directed towards the first lens 200, so that the light emitted from the first lens 200 can be projected onto the light entrance surface, so that the light emitted from the first lens 200 can be projected into the triangular prism through the light entrance surface.

[0074] When the first reflecting member 500 is in the second position, the light exit surface can be opposite to the photosensitive chip 400, so that the light projected into the triangular prism through the light entrance surface can be reflected by the inclined surface of the triangular prism to the light exit surface, and can be projected onto the photosensitive chip 400 through the light exit surface. The photosensitive chip 400 converts the received light signal into an electrical signal to realize imaging.

[0075] In further technical solutions, the inclined surface of the triangular prism can be a non-light-transmitting surface, so that when the first reflecting member 500 is in the second position, the light emitted from the second lens 300 can be prevented from being projected onto the photosensitive chip 400 through the inclined surface of the triangular prism, thereby interfering with the imaging realized by the first lens 200.

[0076] Of course, the first reflecting member 500 can also be a plane mirror arranged obliquely, and the embodiments of the present application do not limit the specific structure and type of the first reflecting member 500.

[0077] In an optional technical solution, when the first reflecting member 500 is in the second position, the first reflecting member 500 can drive the second lens 300 to abut against the inner wall of the housing 100, so as to fix the second lens 300, which is conducive to improving the stability of the second lens 300 and avoiding the situation that the second lens 300 shakes and easily produces abnormal sound.

[0078] In an optional technical solution, the camera module can further include a first driving mechanism 800, which can be arranged on the housing 100 and connected with the first reflecting element 500, and used to drive the first reflecting element 500 to move, so as to drive the first reflecting element 500 to move through the first driving mechanism 800, to realize the switching of the first reflecting element 500 between the first position and the second position. This structure can realize the automatic switching of the first reflecting element 500 between the first position and the second position through the first driving mechanism 800, which is beneficial to improve the intelligence and automation of the camera module, thereby improving the user experience.

[0079] In a further technical solution, the first driving mechanism 800 can include a first magnet 810 and a first electromagnetic coil 820. The first electromagnetic coil 820 can be fixed on the housing 100, and the first magnet 810 can be fixed on the first reflecting element 500. The first electromagnetic coil 820 in the energized state can cooperate with the first magnet 810 to drive the first reflecting element 500 to move. This structure is relatively simple and easy to implement, which is beneficial to reduce the cost of the camera module. Of course, the first electromagnetic coil 820 can be fixed on the first reflecting element 500 and move with the first reflecting element 500. Correspondingly, the first magnet 810 can be fixed on the housing 100. In addition, the first driving mechanism 800 can also be a telescopic driving member, such as an electrostrictive structure member, and the present application embodiment does not limit the specific type of the first driving mechanism 800.

[0080] In order to further avoid the first reflecting element 500 from deviating when switching between the first position and the second position, the first magnet 810 and the first electromagnetic coil 820 can each be a plurality of magnets. The plurality of first electromagnetic coils 820 are arranged on the opposite inner walls of the housing 100, and the plurality of first magnets 810 are arranged on the opposite sides of the first reflecting element 500. Each first electromagnetic coil 820 cooperates with the corresponding first magnet 810. This structure can drive the opposite sides of the first reflecting element 500 by the magnetic force generated by the first electromagnetic coil 820, thereby avoiding the situation that one side of the first reflecting element 500 is easily deviated when being driven by the magnetic force generated by the first electromagnetic coil 820, and thereby improving the reliability and stability of the first driving mechanism 800.

[0081] More optionally, the first electromagnetic coil 820 can be arranged in the housing 100 and opposite to the first magnet 810, thereby being beneficial to reduce the interference when the first electromagnetic coil 820 cooperates with the first magnet 810. Of course, the first electromagnetic coil 820 is arranged on the relatively stationary housing 100, which can facilitate the electrical connection of the first electromagnetic coil 820, and the first electromagnetic coil 820 will not have the problem of easy failure of electrical connection due to the movement of the first reflecting element 500.

[0082] In the embodiment of the present application, the shell 100 can be provided with a first light-transmitting opening 120, and the incident light can pass through the first light-transmitting opening 120 to enter the first lens 200. The shell 100 can also be provided with a second light-transmitting opening 130, and the first light-transmitting opening 120 can be arranged apart from the second light-transmitting opening 130. The incident light can pass through the second light-transmitting opening 130 to enter the second lens 300.

[0083] In the specific working process, when the first reflecting member 500 is located at the first position, the incident light can be projected onto the photosensitive chip 400 after passing through the second light-transmitting opening 130 to enter the second lens 300, so that the camera module can shoot an image through the second lens 300. When the first reflecting member 500 is located at the second position, the incident light can be projected onto the photosensitive chip 400 after passing through the first light-transmitting opening 120 to enter the first lens 200 and then being reflected by the first reflecting member 500, so that the camera module can shoot an image through the first lens 200.

[0084] It should be noted that the light passing through the first lens 200 can be the incident light passing through the first light-transmitting opening 120 to enter the first lens 200, and the light passing through the second lens 300 can be the incident light passing through the second light-transmitting opening 130 to enter the second lens 300. In the embodiment of the present application, the directions of the first light-transmitting opening 120 and the second light-transmitting opening 130 can be consistent or inconsistent.

[0085] In a further technical solution, the shell 100 can be provided with a first light-transmitting opening 120, and the optical axis direction of the first lens 200 can intersect with the direction of the first light-transmitting opening 120, for example, perpendicular to each other. The camera module can further include a second reflecting member 900, which can be arranged in the shell 100 and opposite to the first light-transmitting opening 120. The incident light can pass through the first light-transmitting opening 120, the second reflecting member 900 and the first lens 200, and then be reflected by the first reflecting member 500 to be emitted.

[0086] When the first reflecting member 500 is located at the second position, the incident light can pass through the first light-transmitting opening 120 to enter the second reflecting member 900, and then be reflected by the second reflecting member 900 to pass through the first lens 200 to be projected onto the first reflecting member 500, so as to be reflected by the first reflecting member 500 to the photosensitive chip 400 to realize imaging. In this case, the first lens 200 is arranged between the second reflecting member 900 and the first reflecting member 500, and the light-in surface and the light-out surface of the second reflecting member 900 are opposite to the first light-transmitting opening 120 and the first lens 200, respectively. The optical axis direction of the second lens 300 intersects with the optical axis direction of the first lens 200, for example, perpendicular to each other.

[0087] Further, when the first reflecting element 500 is located at the first position, the optical axis direction of the second lens 300 can be parallel to the orientation of the second light-transmitting port 130, the incident light passes through the second light-transmitting port 130 and enters the second lens 300, and then passes through the second lens 300 and is projected onto the photosensitive chip 400 to realize imaging. In this case, the orientation of the first light-transmitting port 120 can be parallel to the orientation of the second light-transmitting port 130. This structure can make the first lens 200, the first light-transmitting port 120, and the second reflecting element 900 form a periscopic lens, thereby avoiding occupying the size of the orientation of the first light-transmitting port 120 (usually the thickness direction of the electronic device), and being beneficial to the thinning of the electronic device. The periscopic lens is beneficial to long-focus shooting of the camera module.

[0088] In the embodiments of the present application, the second reflecting element 900 can be a triangular prism or a plane mirror. Similarly, the specific structure of the second reflecting element 900 is not limited in the embodiments of the present application.

[0089] Of course, the orientation of the first light-transmitting port 120 can be parallel to the optical axis direction of the first lens 200, and the first light-transmitting port 120 can be opposite to the first lens 200. The light passing through the first light-transmitting port 120 can directly pass through the first lens 200 and be projected onto the first reflecting element 500, and then be reflected by the first reflecting element 500 to the photosensitive chip 400 to realize imaging. In this case, the orientation of the first light-transmitting port 120 can be perpendicular to the orientation of the second light-transmitting port 130.

[0090] In further technical solutions, the first lens 200 can include a plurality of lenses 210, and the plurality of lenses 210 can be movably arranged in the housing 100. Specifically, during the movement of the first reflecting element 500 from the second position to the first position, at least one of the plurality of lenses 210 can move away from the second lens 300, so that the plurality of lenses 210 are gathered in the movement direction of the first reflecting element 500, thereby making the gap between the plurality of lenses 210 smaller when the first reflecting element 500 is located at the first position.

[0091] As described above, during the movement of the first reflecting element 500 from the second position to the first position, the lens 210 farthest from the first reflecting element 500 among the plurality of lenses 210 can remain unchanged, and the other lenses 210 among the plurality of lenses 210 can move away from the second lens 300, thereby realizing the gathering of the plurality of lenses 210 in the movement direction of the first reflecting element 500. Of course, the lens 210 closest to the first reflecting element 500 among the plurality of lenses 210 can move away from the second lens 300, and the other lenses 210 among the plurality of lenses 210 can remain unchanged, thereby realizing the gathering of the plurality of lenses 210 in the movement direction of the first reflecting element 500.

[0092] In this structure, the structure of the first lens 200 is more compact, thereby being capable of reducing the shaking range of the plurality of lenses 210 when the plurality of lenses 210 is impacted by external force, and further being capable of reducing the abnormal sound generated by the shaking of the plurality of lenses 210, and also making the first lens 200 occupy a smaller space.

[0093] During the movement of the first reflecting member 500 from the first position to the second position, at least one of the plurality of lenses 210 can move towards the second lens 300, so that the plurality of lenses 210 are spread in the moving direction of the first reflecting member 500, thereby enabling the plurality of lenses 210 to move to the preset position to ensure the imaging quality.

[0094] Specifically, during the movement of the first reflecting member 500 from the first position to the second position, the lens 210 farthest from the first reflecting member 500 in the plurality of lenses 210 can remain unchanged, and the other lenses 210 in the plurality of lenses 210 can all move towards the second lens 300, so that the plurality of lenses 210 are spread in the moving direction of the first reflecting member 500. Of course, the plurality of lenses 210 can all move towards the second lens 300, so that the plurality of lenses 210 are spread in the moving direction of the first reflecting member 500.

[0095] This structure, by gathering the plurality of lenses 210 when the first reflecting member 500 is located at the first position, thereby saving the space required by the first reflecting member 500, and further being capable of fully utilizing the space in the camera module, avoiding increasing the size of the camera module. At the same time, by spreading the plurality of lenses 210 when the first reflecting member 500 is located at the second position, thereby being capable of ensuring that the first lens 200 can normally shoot while avoiding the plurality of lenses 210 occupying a large space, avoiding increasing the size of the camera module, and further being capable of reducing the space occupied by the camera module in the electronic device, facilitating the layout in the electronic device.

[0096] To further save space, part of the lens 210 can be arranged on the second reflecting member 900 and can be opposite to the first light-transmitting port 120, that is, part of the lens 210 is arranged on the side of the second reflecting member 900 opposite to the first light-transmitting port 120, so that the light passing through the first light-transmitting port 120 can pass through part of the lens 210 and enter the second reflecting member 900, and then be reflected by the second reflecting member 900 to pass through another part of the lens 210 (that is, the lens 210 arranged between the first reflecting member 500 and the second reflecting member 900) and project the first reflecting member 500, so as to be reflected by the first reflecting member 500 to the photosensitive chip 400 to realize imaging. Due to the arrangement of part of the lens 210 on the side of the second reflecting member 900 opposite to the first light-transmitting port 120, the space between the second reflecting member 900 and the first reflecting member 500 can be saved, which is conducive to further reducing the size of the camera module, and further reducing the space occupied by the camera module in the electronic device, and facilitating the layout in the electronic device.

[0097] Of course, the camera module can also include a second driving mechanism, the second driving mechanism can include a plurality of second electromagnetic coils and a plurality of second magnets, the plurality of second electromagnetic coils can be fixed on the housing 100, and the plurality of second magnets can be respectively fixed on the plurality of lenses 210. The plurality of second electromagnetic coils in the energized state can cooperate with the plurality of second magnets to drive the plurality of lenses 210 to move, so that the plurality of lenses 210 can be automatically adjusted, thereby realizing automatic focusing of the first lens 200, and further facilitating the improvement of the user's shooting experience.

[0098] In a further technical solution, the first lens 200 can also include a lens barrel, and part of the housing 100 can serve as the lens barrel. In this way, the housing 100 can serve two purposes, thereby avoiding the need to additionally provide a lens barrel for the first lens 200, so as to save the space occupied by the lens barrel of the first lens 200, and further facilitate the reduction of the size of the camera module. Alternatively, the plurality of lenses 210 can be in rolling cooperation with the lens barrel through a plurality of third rolling bodies 1130, so as to facilitate the adjustment of the lenses and make the movement of the lenses more smooth. Of course, the third rolling body 1130 can be a ball or a roller, and the embodiments of the present application do not limit this.

The side of the second sub-lens 320 away from the first reflecting member 500 is rotatably connected to the bracket 600, and the first sub-lens 310 is connected to the end of the second sub-lens 320 away from the bracket 600 through the elastic member 330, so that the first sub-lens 310 can move relative to the second sub-lens 320.

[0100] Specifically, when the first reflecting member 500 is located at the first position, the side of the second sub-lens 320 close to the first reflecting member 500 can be supported on the support 600, and the light passing through the second light-transmitting port 130 can pass through the first sub-lens 310 and the second sub-lens 320 in sequence and then be projected onto the photosensitive chip 400 to realize imaging. When the first reflecting member 500 is located at the second position, the side of the second sub-lens 320 close to the first reflecting member 500 can be separated from the support 600 and can drive the first sub-lens 310 to move away from the photosensitive chip 400.

[0101] Further, please continue to refer to Figure 7 , the third driving mechanism 340 can include a third electromagnetic coil 341 and a third magnet 342, and the fourth driving mechanism 350 can include a fourth electromagnetic coil 351 and a fourth magnet 352.

The third electromagnetic coil 341 and the fourth electromagnetic coil 351 can be arranged around the first sub-lens 310 and can not interfere with each other. The third electromagnetic coil 341 can drive the first sub-lens 310 to perform focusing movement through the third magnet 342 to realize automatic focusing of the second lens 300, and the fourth electromagnetic coil 351 can drive the first sub-lens 310 to perform anti-shake movement through the fourth magnet 352 to realize automatic anti-shake of the second lens 300, thereby facilitating further improvement of user experience.
