[0003] The present application belongs to the technical field of camera module design, and specifically relates to a camera module and electronic equipment. Background Art
[0004] Electronic devices (such as mobile phones and tablets) are becoming increasingly ubiquitous in our daily lives. To meet diverse photography needs, these devices are often equipped with multiple camera modules. However, the high number of camera modules increases the cost of these devices, contributing to their consistently high prices. Reducing the manufacturing cost of electronic devices is a pressing technical challenge facing manufacturers. Summary of the Invention

When the first reflector is in the first position, the light-emitting surface of the first reflector 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; when the first reflector is in the second position, the light-emitting surface of the first reflector is opposite to the photosensitive chip, so that the light passing through the first lens is projected onto the photosensitive chip after being reflected by the first reflector.

[0009] The technical solution adopted in this application can achieve the following technical effects:
[0010] The camera module disclosed in the embodiment of the present application improves the structure of the camera module involved in the related art, and can switch between a first position and a second position by setting a first reflector, wherein, when the first reflector is in the first position, by setting the light-emitting surface of the first reflector to be staggered with the photosensitive chip, and making the second lens opposite to the photosensitive chip, the light passing through the second lens is projected onto the photosensitive chip, and the light emitted from the first lens is prevented from being reflected by the first reflector onto the photosensitive surface of the photosensitive chip, thereby realizing image capture through the second lens; when the first reflector is in the second position, by setting the light-emitting surface of the first reflector to be opposite to the photosensitive chip, the light passing through the first lens is reflected by the first reflector and projected onto the photosensitive chip, and the light emitted from the second lens is prevented from being projected onto the photosensitive surface of the photosensitive chip, thereby realizing image capture through the first lens. With this structure, the photosensitive chip used by the first lens or the second lens to capture an image is the same photosensitive chip, so that the first lens and the second lens can share one photosensitive chip to achieve imaging, thereby saving photosensitive chips and further reducing the number of photosensitive chips in electronic devices equipped with multiple camera modules, which is beneficial to reducing the manufacturing cost of electronic equipment.

[0020] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0021] The technical solutions disclosed in various embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0022] Please refer to Figures 1 to 7. The embodiments of the present application disclose a camera module, which includes a housing 100, a first lens 200, a second lens 300, a photosensitive chip 400 and a first reflector 500.
[0023] The housing 100 is the foundation of the camera module and serves as a mounting base for the other components of the camera module. The first lens 200, the second lens 300, the photosensitive chip 400, and the first reflector 500 are all housed within the housing 100. Furthermore, the housing 100 also forms some functional spaces or structures, such as the first light-transmitting opening 120 and the second light-transmitting opening 130 described below.
[0024] The first lens 200, the second lens 300, and the photosensitive chip 400 are the core components of the camera module for achieving imaging. The first reflector 500 is the core component that enables the first lens 200 and the second lens 300 to share the same photosensitive chip 400. In addition, the first reflector 500 can be switched between a first position and a second position. By switching the position of the first reflector 500, the camera module can capture images through the first lens 200 or the second lens 300.
[0025] In a specific working process, when the first reflector 500 is in the first position, the light-emitting surface of the first reflector 500 is staggered with the photosensitive chip 400, so that the first lens 200 and the photosensitive chip 400 are staggered, so as to prevent the light emitted from the first lens 200 from being reflected by the first reflector 500 onto the photosensitive surface of the photosensitive chip 400. 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 onto the photosensitive chip 400, and the photosensitive surface of the photosensitive chip 400 receives the light signal, so that the photosensitive chip 400 converts the light signal into an electrical signal, thereby realizing imaging. In this case, the camera module captures an image through the second lens 300.
[0026] When the first reflector 500 is in the second position, the light-emitting surface of the first reflector 500 is opposite to the photosensitive chip 400. Of course, the light-incident surface of the first reflector 500 can be opposite to the first lens 200, so that the light emitted through the first lens 200 is reflected by the first reflector 500 and then projected onto the photosensitive chip 400. Among them, the light emitted through the first lens 200 enters the first reflector 500 through the light-incident surface of the first reflector 500, and then is reflected by the first reflector 500 and emitted from the light-emitting surface of the first reflector 500 and projected onto the photosensitive surface of the photosensitive chip 400. That is, the light emitted through the first lens 200 is indirectly projected onto the photosensitive surface of the photosensitive chip 400 through the first reflector 500. The photosensitive chip 400 is used to convert the optical signal into an electrical signal to achieve imaging. In other words, in this case, the camera module captures an image through the first lens 200.
[0027] The camera module disclosed in the embodiment of the present application improves the structure of the camera module involved in the related art, and can be switched between the first position and the second position by setting the first reflector 500. When the first reflector 500 is in the first position, the light-emitting surface of the first reflector 500 is staggered with the photosensitive chip 400, and the second lens 300 is opposite to the photosensitive chip 400, so that the light passing through the second lens 300 is projected onto the photosensitive chip 400, and the light emitted from the first lens 200 is prevented from being reflected by the second lens 300. A reflective element 500 reflects light onto the photosensitive surface of the photosensitive chip 400, thereby enabling image capture through the second lens 300; when the first reflective element 500 is in the second position, the light-emitting surface of the first reflective element 500 is arranged to be opposite to the photosensitive chip 400, so that the light passing through the first lens 200 is reflected by the first reflective element 500 and then projected onto the photosensitive chip 400, and the light emitted from the second lens 300 is prevented from being projected onto the photosensitive surface of the photosensitive chip 400, thereby enabling image capture through the first lens 200.
[0028] 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 the same photosensitive chip 400 for imaging, thereby saving photosensitive chips 400, and further reducing the number of photosensitive chips 400 in electronic devices equipped with multiple camera modules, which is conducive to reducing the manufacturing cost of electronic devices. 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, avoiding lateral deviation of the image captured when switching from the first lens 200 to the second lens 300.
[0029] Furthermore, since the first lens 200 and the second lens 300 are located in the same camera module, the distance between them is shorter than if they were located in separate camera modules. This reduces the apparent shift in the image captured when switching from the first lens 200 to the second lens 300, thereby improving the user experience. Furthermore, since the first lens 200 and the second lens 300 are both located in the same camera module, installation of the camera module in the electronic device is facilitated and assembly is simplified.
[0030] In a further technical solution, the first lens 200 and the second lens 300 can be respectively arranged on opposite sides of the first reflector 500, that is, the first reflector 500 is arranged between the first lens 200 and the second lens 300. At the same time, the second lens 300 can be rotatably connected to the housing 100, so that the positional relationship between the second lens 300 and the photosensitive chip 400 can be adjusted by rotating the second lens 300.
[0031] During the specific working process, when the first reflector 500 is in 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, so that the light passing through the second lens 300 is projected onto 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 capture through the second lens 300.
[0032] When the first reflector 500 is in the second position, the second lens 300 can be rotated so that the second lens 300 can be away from the photosensitive surface of the photosensitive chip 400, thereby preventing the light emitted from the second lens 300 from being projected onto the photosensitive chip 400. At the same time, the light-emitting surface of the first reflector 500 can be opposite to the photosensitive chip 400. Of course, the light-incident surface of the first reflector 500 can be opposite to the first lens 200, so that the light emitted through the first lens 200 passes through the light-incident surface of the first reflector 500 and enters the first reflector 500, and then is reflected by the first reflector 500 and emitted from the light-emitting surface of the first reflector 500 and projected onto 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 capture through the first lens 200.
[0033] This structure allows the second lens 300 to be rotated so that it can be moved away from or closer to the photosensitive surface of the photosensitive chip 400, thereby saving the space required for the movable second lens 300, which is beneficial for reducing the size of the camera module. It also makes it easier to subsequently reset the second lens 300 to a position relative to the photosensitive chip 400.
[0034] In one embodiment, the side of the second lens 300 facing away from the first reflector 500 can be rotatably connected to the housing 100 so that the side of the second lens 300 opposite to the first reflector 500 can rotate around the side of the second lens 300 opposite to the first reflector 500.
[0035] During the specific working process, when the first reflector 500 moves from the first position to the second position, the first reflector 500 can be inserted between the second lens 300 and the photosensitive chip 400 to keep the second lens 300 away from the photosensitive surface of the photosensitive chip 400, and the first reflector 500 can push the second lens 300 to rotate, so that the first reflector 500 and the second lens 300 can be better linked, avoiding the need to set up an additional driving mechanism to drive the second lens 300 to rotate.
[0036] In addition, when the first reflector 500 is in the first position, the side of the second lens 300 opposite to the first reflector 500 can be close to the photosensitive chip 400, so that the second lens 300 and the photosensitive chip 400 are overlapped, so that the second lens 300 and the photosensitive surface of the photosensitive chip 400 are opposite, so that the light passing through the second lens 300 can be projected onto 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 capture through the second lens 300.
[0037] When the first reflector 500 is in the second position, the first reflector 500 can be inserted between the second lens 300 and the photosensitive chip 400. The side of the second lens 300 opposite to the first reflector 500 can be pushed by the first reflector 500 and turned away from the photosensitive chip 400, so that the second lens 300 is away from the photosensitive surface of the photosensitive chip 400, avoiding the light passing through the second lens 300 from being projected onto the photosensitive chip 400.
[0038] At the same time, the light-emitting surface of the first reflector 500 can be opposite to the photosensitive chip 400, and the light-incident surface of the first reflector 500 can be opposite to the first lens 200, so that the light emitted through the first lens 200 passes through the light-incident surface of the first reflector 500 and enters the first reflector 500, and then is reflected by the first reflector 500 and emitted from the light-emitting surface of the first reflector 500 and projected onto the photosensitive surface of the photosensitive chip 400. The photosensitive chip 400 can convert the light signal into an electrical signal to realize imaging, so as to realize image capture through the first lens 200.
[0039] This structure allows the second lens 300 to be moved away from or closer to the photosensitive surface of the photosensitive chip 400 by rotating the second lens 300, and when the first reflector 500 is in the first position, the second lens 300 can be superimposed on the first reflector 500, so that the structure between the first reflector 500 and the second lens 300 is more compact, thereby saving space and helping to reduce the size of the camera module, and also making it easier for the second lens 300 to be subsequently reset to a position opposite to the photosensitive chip 400.
[0040] Of course, in other embodiments, the second lens 300 can be connected to the first reflector 500, so as to follow the movement of the first reflector 500 relative to the housing 100, thereby achieving switching between the first position and the second position. Of course, this connection method of the second lens 300 can also achieve the purpose of the embodiment of the present application, but in this case, the second lens 300 does not rotate relative to the housing 100, but moves 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.
[0041] In a feasible technical solution, the camera module may further include a bracket 600, which may be fixed inside the housing 100 and may be covered on the photosensitive chip 400, thereby protecting the photosensitive chip 400 and preventing the first reflector 500 and the second lens 300 from colliding or wearing the photosensitive chip 400, thereby causing a malfunction of the photosensitive chip 400. At the same time, the bracket 600 also provides an installation base for the second lens 300, so that the second lens 300 is mounted in the direction of the photosensitive chip 400.
[0042] The second lens 300 can be mounted on a bracket 600. The side of the second lens 300 opposite to the first reflector 500 can be rotatably connected to the bracket 600, so that the bracket 600 can provide a mounting base for the second lens 300, allowing the second lens 300 to be indirectly connected to the housing 100 via the bracket 600. Of course, the second lens 300 can also be directly connected to the housing 100. At the same time, the bracket 600 can be provided with a light avoidance hole 610. The light avoidance hole 610 can be opposite to the photosensitive chip 400, so that light emitted from the second lens 300 or light reflected by the first reflector 500 can pass through the light avoidance hole 610 and be projected onto the photosensitive chip 400.
[0043] During operation, when the first reflector 500 is in the first position, the side of the second lens 300 closest to the first reflector 500 can be supported on the bracket 600, so that the second lens 300 is supported on the bracket 600 and faces the photosensitive chip 400. In this case, the light avoidance hole 610 faces the second lens 300, allowing light passing through the second lens 300 to pass through the light avoidance hole 610 and be projected onto the photosensitive chip 400. The photosensitive chip 400 converts the optical signal into an electrical signal to achieve imaging, thereby achieving image capture through the second lens 300.
[0044] When the first reflector 500 is in the second position, the side of the second lens 300 close to the first reflector 500 can be away from the bracket 600, and the first reflector 500 can be inserted between the side of the second lens 300 close to the first reflector 500 and the photosensitive chip 400. In this case, the first reflector 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-emitting surface of the first reflector 500 is opposite to the light-sensitive surface of the photosensitive chip 400. Of course, the light-incident surface of the first reflector 500 can be opposite to the first lens 200, and the light-emitting surface of the first reflector 500 can also be opposite to the light-avoiding hole 610, so that the light emitted from the first lens 200 can be reflected by the first reflector 500 and can pass through the light-avoiding hole 610 and be projected onto the photosensitive chip 400. The photosensitive chip 400 can convert the light signal into an electrical signal to realize imaging, so as to realize image capture through the first lens 200.
[0045] In a further technical solution, the camera module may further include a filter 1200. The filter 1200 may be provided with a light avoidance hole 610 and may be opposite to the photosensitive chip 400. The photosensitive chip 400 may be located between the filter 1200 and the housing 100, so that the light passing through the second lens 300 or the light reflected by the first reflector 500 can pass through the filter 1200 and be projected onto the photosensitive chip 400. With this structure, the optical filter 1200 can filter out some unnecessary light (such as red light) in the light reflected by the first reflector 500 to the photosensitive chip 400 or projected from the second lens 300 to the photosensitive chip 400, so that some light of a specific wavelength not needed by the camera module and reflected by the first reflector 500 or emitted from the second lens 300 does not pass through the optical filter 1200, thereby allowing light of other wavelengths reflected by the first reflector 500 or passing through the second lens 300 to pass through the optical filter 1200 and be projected onto the photosensitive chip 400 to achieve imaging, which is beneficial to improving the imaging quality.
[0046] In addition, in this structure, the filter 1200 used by the first lens 200 or the second lens 300 for 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 electronic devices equipped with multiple camera modules, which is conducive to further reducing the cost of electronic equipment.
[0047] In an optional technical solution, the camera module may further include a circuit board 1000, the circuit board 1000 may be fixed to the housing 100, the photosensitive chip 400 may be fixed to the circuit board 1000, and may be electrically connected to the circuit board 1000, and the bracket 600 may be fixed to the circuit board 1000 or the housing 100. With this structure, the circuit board 1000 can provide an installation base for the photosensitive chip 400, and can also achieve electrical conduction of the photosensitive chip 400, so that the circuit board 1000 can serve a dual purpose, thereby making full use of the circuit board 1000. In addition, the circuit board 1000 is conducive to simplifying the circuit, avoiding the use of connecting wires to achieve electrical connection and causing the circuit to be too complicated. Specifically, the circuit board 1000 can be a printed circuit board or a soft-hard combination circuit board, and the embodiments of the present application are not limited to this.
[0048] In a feasible embodiment, the second lens 300 may be provided with a first magnetic member 710, and the bracket 600 may be provided with a second magnetic member 720. When the first reflective member 500 is in the first position, the first magnetic member 710 may be magnetically attracted to the second magnetic member 720, so that the light-emitting surface of the second lens 300 may be opposite to the photosensitive chip 400. Furthermore, the second lens 300 may be fixed by the 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 bracket 600, thereby reducing the risk of the second lens 300 being easily rotated by external forces and affecting the imaging quality.
[0049] Optionally, when the first reflective member 500 is in the second position, the first magnetic member 710 can magnetically repel the second magnetic member 720. In this case, the first magnetic member 710 and the second magnetic member 720 repel each other, making it easier for the side of the second lens 300 away from the first reflective member 500 to separate from the bracket 600. This can reduce the resistance encountered by the first reflective member 500 when inserted between the second lens 300 and the bracket 600, thereby making it easier for the first reflective 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.
[0050] In a further technical solution, the side of the bracket 600 close to the first reflector 500 may have a first guide slope 620, and the bracket 600 may have a second support surface 630. The first guide slope 620 may be connected to the second support surface 630 to guide the first reflector 500 to move to the second support surface 630 through the first guide slope 620 to avoid obstructing the movement of the first reflector 500.
[0051] During the process of the first reflector 500 moving from the first position toward the second position, the first reflector 500 moves along the first guide slope 620, thereby being inserted between the second lens 300 and the bracket 600 to separate the second lens 300 and the photosensitive chip 400. The first reflector 500 moves to the second position above the second support surface 630 through the first guide slope 620.
[0052] Specifically, when the first reflector 500 is in the second position, the first reflector 500 can be supported on the second support surface 630. Of course, the first reflector 500 may not be supported on the second support surface 630, but supported on the first support surface 110 described later, for example, supported on the first support surface 110 by the first rolling body 1110 described later. In this case, the first reflector 500 may not be in contact with the second support surface 630.
[0053] In a further technical solution, the housing 100 may have a first supporting surface 110, which may be located below the second supporting surface 630. When the first reflector 500 is in the first position, the first reflector 500 may be supported above the first supporting surface 110. The first supporting surface 110 may be provided with a first track 111, and the first reflector 500 may be switched between the first position and the second position by a first rolling body 1110 that rolls with the first track 111.
[0054] In this structure, the first reflector 500 rolls with the first supporting surface 110 through the first rolling body 1110, so that there is less friction between the first reflector 500 and the first supporting surface 110, so that the first reflector 500 can switch between the first position and the second position more easily and smoothly, and at the same time can reduce the wear on the first reflector 500 and the first supporting surface 110, which is beneficial to extend the service life of the first reflector 500 and the first supporting surface 110.
[0055] Optionally, the first rolling body 1110 can be partially embedded in the first reflective member 500, so that the first rolling body 1110 can be connected to the first reflective member 500 by rolling, and can guide the movement of the first reflective member 500 through the cooperation between the first rolling body 1110 and the first track 111, so as to avoid the first reflective member 500 from offset when switching between the first position and the second position, thereby affecting the imaging quality.
[0056] Of course, the first reflector 500 may be provided with a second guide slope 510 to guide the side of the second lens 300 opposite to the first reflector 500 to move on the second guide slope 510, thereby making it easier for the first reflector 500 to move between the second lens 300 and the bracket 600.
[0057] At the same time, the second guide slope 510 can be provided with a second track 511. During the movement of the first reflector 500 from the first position to the second position, the first reflector 500 can move relative to the second lens 300 via the second rolling element 1120 that cooperates with the second track 511, thereby driving the second lens 300 to rotate. In this structure, the second lens 300 rolls with the first reflector 500 via the second rolling element 1120, resulting in less friction between the second lens 300 and the first reflector 500. This further facilitates the movement of the first reflector 500 between the second lens 300 and the bracket 600, allowing the first reflector 500 to move more easily and smoothly to the second position. In addition, this structure can minimize wear on the second lens 300 and the first reflector 500, thereby helping to extend the service life of the second lens 300 and the first reflector 500.
[0058] Optionally, the second rolling body 1120 can be partially embedded in the side of the second lens 300 opposite to the first reflector 500, so that the second rolling body 1120 is rotatably connected to the second lens 300, and the cooperation between the second track 511 and the second rolling body 1120 can prevent the first reflector 500 from shifting during movement, thereby affecting the imaging quality.
[0059] The first track 111, the second track 511, the first rolling element 1110, and the second rolling element 1120 can all be multiple. The multiple first rolling elements 1110 can respectively roll with the multiple first tracks 111, and the multiple second rolling elements 1120 can respectively roll with the multiple second tracks 511. Of course, each first track 111 and each second track 511 can respectively roll with some of the multiple first rolling elements 1110 and some of the multiple second rolling elements 1120, thereby making the cooperation between the first reflector 500 and the first support surface 110 and the cooperation between the second lens 300 and the first reflector 500 more stable. Specifically, the first rolling element 1110 and the second rolling element 1120 can both be balls or rollers, which is not limited in this embodiment of the present application.
[0060] In the embodiment of the present application, the first reflector 500 may be a prism, the inclined surface of the prism may be a second guiding inclined surface 510, and the two right-angled surfaces of the prism may be a light incident surface and a light exiting surface, respectively. The light incident surface may face the first lens 200 so that the light emitted from the first lens 200 can be projected onto the light incident surface, so that the light emitted from the first lens 200 can enter the prism through the light incident surface.
[0061] When the first reflector 500 is in the second position, the light-emitting surface can be opposite to the photosensitive chip 400, so that the light entering the prism through the light-incident surface can be reflected by the inclined surface of the prism to the light-emitting surface, and can be projected to the photosensitive chip 400 through the light-emitting surface. The photosensitive chip 400 converts the received light signal into an electrical signal to achieve imaging.
[0062] In a further technical solution, the inclined surface of the prism can be a non-light-transmitting surface, so that when the first reflector 500 is in the second position, it can prevent the light emitted from the second lens 300 from passing through the inclined surface of the prism and projecting onto the photosensitive chip 400, thereby interfering with the imaging achieved by the first lens 200.
[0063] Of course, the first reflector 500 may also be a tilted plane reflector, and the embodiment of the present application does not limit the specific structure and type of the first reflector 500.
[0064] In an optional technical solution, when the first reflector 500 is in the second position, the first reflector 500 can drive the second lens 300 to lean against the inner wall of the shell 100, thereby fixing the second lens 300, which is beneficial to improving the stability of the second lens 300 and avoiding the situation where the second lens 300 shakes and easily produces abnormal noise.
[0065] In one feasible technical solution, the camera module may further include a first drive mechanism 800. The first drive mechanism 800 may be disposed in the housing 100 and connected to the first reflector 500 to drive the first reflector 500 to move. The first drive mechanism 800 thereby drives the first reflector 500 to move, thereby enabling the first reflector 500 to switch between the first position and the second position. This structure enables the first drive mechanism 800 to automatically switch the first reflector 500 between the first position and the second position, thereby improving the intelligence and automation of the camera module and thereby enhancing the user experience.
[0066] In a further technical solution, the first drive mechanism 800 may include a first magnet 810 and a first electromagnetic coil 820. The first electromagnetic coil 820 may be fixed to the housing 100, and the first magnet 810 may be fixed to the first reflector 500. When energized, the first electromagnetic coil 820 cooperates with the first magnet 810 to drive the first reflector 500 to move. This structure is relatively simple and easy to implement, which helps reduce the cost of the camera module. Of course, the first electromagnetic coil 820 can be fixed to the first reflector 500 and move with the first reflector 500, and accordingly, the first magnet 810 can be fixed to the housing 100. In addition, the first drive mechanism 800 can also be a telescopic drive component, such as an electrostrictive structure. The embodiments of the present application do not limit the specific type of the first drive mechanism 800.
[0067] To further prevent the first reflector 500 from shifting when switching between the first position and the second position, the first magnet 810 and the first electromagnetic coil 820 can be multiple. The multiple first electromagnetic coils 820 are respectively arranged on two opposing inner walls of the housing 100, and the multiple first magnets 810 are respectively arranged on opposite sides of the first reflector 500, and each first electromagnetic coil 820 is respectively matched with a corresponding first magnet 810. With this structure, the opposite sides of the first reflector 500 can be driven by the magnetic force generated by the first electromagnetic coil 820, thereby preventing one side of the first reflector 500 from being driven by the magnetic force generated by the first electromagnetic coil 820, which is prone to shifting. This is conducive to improving the reliability and stability of the driving of the first driving mechanism 800.
[0068] Alternatively, the first electromagnetic coil 820 may be disposed within the housing 100 and may be opposite the first magnet 810, thereby reducing interference experienced by the first electromagnetic coil 820 when engaged with the first magnet 810. Of course, disposing the first electromagnetic coil 820 on the relatively stationary housing 100 facilitates electrical connection of the first electromagnetic coil 820, and avoids the problem of electrical connection failure caused by the first electromagnetic coil 820 following the movement of the first reflector 500.
[0069] In an embodiment of the present application, the shell 100 may be provided with a first light-transmitting opening 120, through which incident light may pass into the first lens 200. The shell 100 may also be provided with a second light-transmitting opening 130, and the first light-transmitting opening 120 may be spaced apart from the second light-transmitting opening 130, through which incident light may pass into the second lens 300.
[0070] In a specific operation process, when the first reflector 500 is in the first position, incident light passes through the second light-transmitting opening 130 and enters the second lens 300, and then is projected onto the photosensitive chip 400, so that the camera module captures an image through the second lens 300. When the first reflector 500 is in the second position, incident light passes through the first light-transmitting opening 120 and enters the first lens 200, and then is reflected by the first reflector 500 and is projected onto the photosensitive chip 400, so that the camera module captures an image through the first lens 200.
[0071] It should be noted that the light passing through the first lens 200 may be incident light entering the first lens 200 through the first light transmission port 120, and the light passing through the second lens 300 may be incident light entering the second lens 300 through the second light transmission port 130. In the embodiment of the present application, the orientations of the first light transmission port 120 and the second light transmission port 130 may be the same or different.
[0072] In a further technical solution, the shell 100 may be provided with a first light-transmitting port 120, and the optical axis direction of the first lens 200 may intersect with the direction of the first light-transmitting port 120, for example, the two are perpendicular, and the camera module may further include a second reflector 900, which may be arranged in the shell 100 and may be opposite to the first light-transmitting port 120. The incident light may pass through the first light-transmitting port 120, the second reflector 900 and the first lens 200, and then be reflected by the first reflector 500 and emitted.
[0073] When the first reflector 500 is in the second position, incident light passes through the first light-transmitting opening 120 and enters the second reflector 900. Thereafter, the incident light is reflected by the second reflector 900, passes through the first lens 200, and projects onto the first reflector 500, thereby being reflected by the first reflector 500 onto the photosensitive chip 400 to achieve imaging. In this case, the first lens 200 is disposed between the second reflector 900 and the first reflector 500, and the light-entry surface and light-exit surface of the second reflector 900 are opposite to the first light-transmitting opening 120 and the first lens 200, respectively. The optical axis of the second lens 300 intersects with, for example, is perpendicular to, the optical axis of the first lens 200.
[0074] Furthermore, when the first reflector 500 is in the first position, the optical axis direction of the second lens 300 can be parallel to the direction 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 achieve imaging. In this case, the direction of the first light-transmitting port 120 can be parallel to the direction of the second light-transmitting port 130. This structure enables the first lens 200, the first light-transmitting port 120, and the second reflector 900 to form a periscope lens, thereby avoiding occupying the dimension in the direction of the first light-transmitting port 120 (usually the thickness direction of the electronic device), which is conducive to the thinning of the electronic device. The periscope lens is conducive to the camera module to perform telephoto shooting.
[0075] In the embodiment of the present application, the second reflector 900 may be a prism or a plane reflector. Similarly, the embodiment of the present application does not limit the specific structure of the second reflector 900.
[0076] Of course, the orientation of the first light-transmitting port 120 can be parallel to the optical axis of the first lens 200, and the first light-transmitting port 120 can be opposite to the first lens 200. Light passing through the first light-transmitting port 120 can directly pass through the first lens 200 and project onto the first reflective element 500, thereby being reflected by the first reflective element 500 onto the photosensitive chip 400 to achieve 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.
[0077] In a further technical solution, the first lens 200 may include a plurality of lenses 210, and the plurality of lenses 210 may be movably disposed within the housing 100. Specifically, during the process of the first reflector 500 moving from the second position to the first position, at least one of the plurality of lenses 210 may move in a direction away from the second lens 300, so that the plurality of lenses 210 converge in the moving direction of the first reflector 500, thereby ensuring that there is a small gap between the plurality of lenses 210 when the first reflector 500 is in the first position.
[0078] As described above, during the process of the first reflector 500 moving from the second position to the first position, the lens 210 farthest from the first reflector 500 among the multiple lenses 210 can be kept unchanged, and the other lenses 210 among the multiple lenses 210 can be moved in a direction away from the second lens 300, thereby achieving the convergence of the multiple lenses 210 in the moving direction of the first reflector 500. Of course, the lens 210 closest to the first reflector 500 among the multiple lenses 210 can also be moved in a direction away from the second lens 300, and the other lenses 210 among the multiple lenses 210 can be kept unchanged, thereby achieving the convergence of the multiple lenses 210 in the moving direction of the first reflector 500.
[0079] In this structure, the structure of the first lens 200 is more compact, which can reduce the shaking amplitude of the multiple lenses 210 when they are impacted by external force, thereby helping to reduce the abnormal noise generated by the shaking of the multiple lenses 210, and also makes the first lens 200 occupy a smaller space.
[0080] During the process of the first reflector 500 moving from the first position to the second position, at least one of the multiple lenses 210 can move toward the direction close to the second lens 300, so that the multiple lenses 210 are dispersed in the moving direction of the first reflector 500, thereby enabling the multiple lenses 210 to move to the preset position to ensure imaging quality.
[0081] Specifically, during the process of the first reflector 500 moving from the first position to the second position, the lens 210 farthest from the first reflector 500 among the multiple lenses 210 can be kept unchanged, and the other lenses 210 among the multiple lenses 210 can be moved in a direction close to the second lens 300, so that the multiple lenses 210 are dispersed in the moving direction of the first reflector 500. Of course, the multiple lenses 210 can also be dispersed in the moving direction of the first reflector 500 by moving the multiple lenses 210 in a direction close to the second lens 300.
[0082] This structure converging the multiple lenses 210 when the first reflector 500 is in the first position saves space required for the first reflector 500, thereby fully utilizing the space within the camera module and avoiding increasing the size of the camera module. Simultaneously, by spreading the multiple lenses 210 when the first reflector 500 is in the second position, the first lens 200 can be guaranteed to be able to shoot normally while avoiding the multiple lenses 210 occupying a large space and increasing the size of the camera module. This helps reduce the space occupied by the camera module in the electronic device and facilitates its layout within the electronic device.
[0083] To further save space, a partial lens 210 can be disposed on the second reflector 900 and can be opposite the first light-transmitting opening 120. That is, the partial lens 210 is disposed on the side of the second reflector 900 opposite the first light-transmitting opening 120, so that light passing through the first light-transmitting opening 120 can pass through the partial lens 210 and enter the second reflector 900, then be reflected by the second reflector 900 and pass through another partial lens 210 (that is, the lens 210 disposed between the first reflector 500 and the second reflector 900) to project onto the first reflector 500, thereby being reflected by the first reflector 500 onto the photosensitive chip 400 to achieve imaging. In this structure, since the partial lens 210 is disposed on the side of the second reflector 900 opposite the first light-transmitting opening 120, it can save space between the second reflector 900 and the first reflector 500, which is conducive to further reducing the size of the camera module, and thus further reducing the space occupied by the camera module in the electronic device, facilitating layout within the electronic device.
[0084] Of course, the camera module can also include a second driving mechanism, which can include multiple second electromagnetic coils and multiple second magnets. The multiple second electromagnetic coils can be fixed on the shell 100, and the multiple second magnets can be fixed on the multiple lenses 210 respectively. The multiple second electromagnetic coils in the energized state can cooperate with the multiple second magnets to drive the multiple lenses 210 to move, so that the multiple lenses 210 can be automatically adjusted, thereby realizing automatic focusing of the first lens 200, which is beneficial to further improve the user's shooting experience.
[0085] In a further technical solution, the first lens 200 may further include a lens barrel, and a portion of the housing 100 may serve as the lens barrel. With this structure, the housing 100 can serve two purposes, avoiding the need to provide an additional lens barrel for the first lens 200, thereby saving space occupied by the lens barrel of the first lens 200, and further helping to reduce the size of the camera module. Optionally, the plurality of lenses 210 may be respectively rolled with the lens barrel by a plurality of third rolling bodies 1130 to facilitate adjustment of the lenses and make the movement of the lenses smoother. Of course, the third rolling body 1130 may be a ball or a roller, and this embodiment of the application is not limited thereto.
[0086] In the embodiment of the present application, as shown in FIG7 , the second lens 300 may include a first sub-lens 310, a second sub-lens 320, an elastic member 330, a third driving mechanism 340, and a fourth driving mechanism 350. The side of the second sub-lens 320 away from the first reflector 500 may be rotatably connected to the bracket 600, and the first sub-lens 310 may be connected to the end of the second sub-lens 320 away from the bracket 600 via the elastic member 330, so that the first sub-lens 310 can move relative to the second sub-lens 320.
[0087] Specifically, when the first reflector 500 is in the first position, the side of the second sub-lens 320 closest to the first reflector 500 can be supported on the bracket 600. Light passing through the second light-transmitting opening 130 can sequentially pass through the first sub-lens 310 and the second sub-lens 320 and be projected onto the photosensitive chip 400 to achieve imaging. When the first reflector 500 is in the second position, the side of the second sub-lens 320 closest to the first reflector 500 can be separated from the bracket 600, thereby moving the first sub-lens 310 away from the photosensitive chip 400.
[0088] Further, referring to FIG. 7 , the third driving mechanism 340 may include a third electromagnetic coil 341 and a third magnet 342, and the fourth driving mechanism 350 may include a fourth electromagnetic coil 351 and a fourth magnet 352. The third electromagnetic coil 341 and the fourth electromagnetic coil 351 may be respectively fixed to the second sub-lens 320, and the third magnet 342 and the fourth magnet 352 may be respectively fixed to the first sub-lens 310. The third electromagnetic coil 341 and the fourth electromagnetic coil 351 may both be disposed around the first sub-lens 310 without interfering with each other. The third electromagnetic coil 341 may drive the first sub-lens 310 to perform focusing motion via the third magnet 342, thereby achieving automatic focusing of the second lens 300. The fourth electromagnetic coil 351 may drive the first sub-lens 310 to perform anti-shake motion via the fourth magnet 352, thereby achieving automatic anti-shake of the second lens 300, thereby further improving the user experience.
[0089] In an optional technical solution, multiple elastic members 330 may be provided, thereby improving the reliability and stability of the connection between the first sub-lens 310 and the second sub-lens 320. Furthermore, multiple third magnets 342 cooperating with the third electromagnetic coil 341 and multiple fourth magnets 352 cooperating with the fourth electromagnetic coil 351 may be provided. This makes it easier for the third electromagnetic coil 341 and the fourth electromagnetic coil 351 to drive the first sub-lens 310 to move via multiple third magnets 342 and multiple fourth magnets 352, respectively, thereby improving the driving efficiency of the third and fourth driving mechanisms 340 and 350. Specifically, the elastic member 330 may be a spring or rubber, which is not limited in this embodiment of the present application.
