TECHNICAL FIELD

[0001] The application belongs to the technical field of electronic equipment, and particularly relates to an electronic equipment. BACKGROUND

[0002] The camera module is an important component in electronic equipment such as mobile phones, and in order to improve the shooting effect, the camera module is usually also provided with a flash. Since the small size flash of common high current instantaneous flash is quite different from the light supplement effect of natural light continuous irradiation, the real sense of the photographed image is poor, so more and more manufacturers begin to use ring light. At present, the optical design of the ring light usually includes two kinds, one is a lamp chain ring arrangement scheme, but since the overall volume is relatively large, it is not conducive to products with strict design requirements on space demand such as mobile phones; the other includes a conic surface light distribution cover, which designs the structure of the conic surface, so that the light emitted by the light supplement lamp monomer located at the center of the light distribution cover can be emitted in a ring shape. However, since the light supplement structure of the light supplement lamp monomer needs to be located at the center of the light distribution cover, the camera module can only be installed below or on the side of the light distribution cover, thereby adversely affecting the thickness size of the electronic equipment.

[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some 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 skilled in the art without creative work fall within the scope of protection of the present application.

[0022] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually a class, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0023] The embodiments of the present application disclose an electronic device, which can be a mobile phone or a tablet computer, etc. As shown in the figure, Figures 1-6 The electronic device includes a camera module 100, an optical lens 200, and a plurality of light supplement monomers 310.

[0024] The camera module 100 can generally include a photosensitive chip and a lens group, etc. The optical lens 200 is used to provide light distribution for the light supplement monomers 310. The light supplement monomers 310 are monomer light supplement lamps, which have a constant light function. The parameters of the plurality of light supplement monomers 310 can be the same, or can be different according to the actual situation of the layout position, etc.

[0025] The optical lens 200 is a closed loop structure as a whole, that is, the optical lens 200 has a closed loop optical surface, but it does not mean that any optical surface in the optical lens 200 is a closed loop structure. In detail, in the embodiment of the present application, the light exit surface 202 of the optical lens 200 is a closed circular ring structure, so that the light emitted by the light supplement unit 310 can present a ring-shaped light source form after being emitted from the light exit surface 202 of the optical lens 200.

[0026] In the process of assembling the electronic device, since the optical lens 200 is a closed loop structure, the optical lens 200 can be arranged around the camera module 100, based on which, in the optical axis direction of the camera module 100, that is, in the thickness direction of the electronic device, the optical lens 200 and the camera module 100 can at least partially overlap, thereby reducing the thickness of the electronic device and the entire electronic device to a certain extent. At the same time, since the optical lens 200 is arranged around the camera module 100, the light supplement center of the optical lens 200 can coincide or substantially coincide with the shooting center of the camera module 100, and the light exit surface 202 of the optical lens 200 is a closed circular ring structure, thereby the light supplement effect of the optical lens 200 is relatively good, so as to improve the shooting effect of the camera module 100.

[0027] As above, the optical lens 200 has a light exit surface 202, in order to ensure that the light emitted by the optical lens 200 can correspond to the shooting area of the camera module 100, in the embodiment of the present application, the light exit surface 202 is arranged towards the light entrance side of the camera module 100, so that the light emitted through the light exit surface 202 can be irradiated on the light entrance side of the camera module 100, that is, in the area to be shot by the camera module 100. Specifically, the light exit surface 202 can be a curved surface, for example, the light exit surface 202 can be a convex surface, in which case, the light exit surface 202 can provide a diverging effect for the light. In other embodiments of the present application, the light exit surface 202 is a plane, and the light exit surface 202 is perpendicular to the optical axis direction of the camera module 100, so that the light after being lighted by the first light distribution surface 203 can be emitted vertically from the light exit surface 202.

[0028] Correspondingly, the optical lens 200 also has an entrance surface 201, and each light supplementing unit 310 is arranged towards the entrance surface 201, so that the light emitted by each light supplementing unit 310 can be incident into the optical lens 200 from the entrance surface 201. Specifically, in the radial direction of the optical lens 200, the light supplementing unit 310 can be arranged outside the entrance surface 201, so that in the case that the light supplementing unit 310 is working, the light emitted by the light supplementing unit 310 can enter the optical lens 200 through the entrance surface 201 and be distributed by the optical lens 200, that is, the direction of the entrance surface 201 is related to the specific structure and other parameters of the optical lens 200. For example, if the light emitted by the light supplementing unit 310 is directly propagated to the first distribution surface 203 after being incident from the entrance surface 201, then the entrance surface 201 and the light supplementing unit 310 can be located at the outer side of the optical lens 200. Correspondingly, in the case that the optical lens 200 includes other distribution surfaces, the entrance surface 201 and the light supplementing unit 310 can be correspondingly arranged at other positions of the optical lens 200. In addition, the entrance surface 201 can also be a curved surface, such as a concave surface, so as to provide a converging effect for the light rays and improve the utilization rate of the light supplementing unit 310. In other embodiments of the present application, the entrance surface 201 can also be a flat surface to reduce the processing and design difficulty of the entire optical lens 200.

[0029] At the same time, in order to improve the light supplementing effect of the electronic device, especially the uniformity of the light supplementing of the optical lens 200 in the circumferential direction thereof, the plurality of light supplementing units 310 can be distributed along the circumferential direction of the optical lens 200, so that different light supplementing units 310 can supply light at different positions of the optical lens 200, and after being distributed and dispersed by the optical lens 200, they can complement each other to form a ring-shaped illumination effect. More specifically, the plurality of light supplementing units 310 are uniformly and spacedly distributed in the circumferential direction of the optical lens 200. Of course, the number of light supplementing units 310 can be two. In order to improve the light supplementing effect of the electronic device as much as possible, in one specific embodiment of the present application, the number of light supplementing units 310 can be equal to or greater than 3. At the same time, in order to prevent the assembly difficulty and cost from being significantly increased due to the relatively large number of light supplementing units 310, in the present application, the upper limit of the number of light supplementing units 310 can be set, which can be 6, 8 or 10, etc. Since the number of light supplementing units 310 in the electronic device disclosed in the embodiments of the present application is less than or much less than the number of light supplementing units 310 in a common lamp chain type ring-shaped light supplementing lamp, the cost of the electronic device disclosed in the embodiments of the present application can still be relatively low, the required assembly space and structural design difficulty are relatively small, and the heat dissipation is good.

[0030] As described above, the optical lens 200 is used to convert the divergent light emitted by the plurality of light supplementing units 310 into a ring-shaped light supplementing effect. For this purpose, in the embodiments of the present application, as shown in FIG. 2, the optical lens 200 can include a first distribution surface 203 and a second distribution surface 205, and the first distribution surface 203 and the second distribution surface 205 can be arranged in the radial direction of the optical lens 200. Specifically, the first distribution surface 203 can be arranged at the outer side of the optical lens 200, and the second distribution surface 205 can be arranged at the inner side of the optical lens 200. In this way, the light emitted by the light supplementing unit 310 can be incident from the entrance surface 201, propagate to the first distribution surface 203, and then propagate to the second distribution surface 205, so as to be distributed and dispersed by the optical lens 200. Figures 3-5As shown, the optical lens 200 also has a first light distribution surface 203, in the radial direction of the optical lens 200, the light exit surface 202 and the first light distribution surface 203 are both located on the inner side of the light entrance surface 201, and in the direction of the optical axis of the camera module, the first light distribution surface 203 is located on the side of the light exit surface close to the light supplementing unit 310. In a popular way, it can be considered that the light exit surface 202 and the first light distribution surface 203 are both located on the inner side of the ring of the optical lens 200, and the light entrance surface 201 is located on the outer side of the ring of the optical lens 200, at the same time, the light exit surface 202 is located on the outer side end surface of the optical lens 200, and the light entrance surface 201 is located on the inner side end surface of the optical lens.

[0031] In this case, since the optical lens 200 is a ring structure as a whole, and the first light distribution surface 203 is located on the inner side of the ring of the optical lens 200, so that the first light distribution surface 203 can actually provide a reflection effect as an inner surface of the optical lens 200, in this case, as shown, Figure 5 so that the light incident on the light entrance surface 201 located on the outer side of the ring of the optical lens 200 can be reflected at the first light distribution surface 203 and shot to the light exit surface 202 located on the outer side thereof, so that the light is shot out from the light exit surface 202 to the outside of the optical lens 200.

[0032] And in the embodiment of the present application, by designing the surface type of the first light distribution surface 203, the first light distribution surface 203 can provide a divergence effect for the light, and the divergence direction is the circumferential direction of the optical lens 200. More intuitively, a bundle of light is incident to a part of the first light distribution surface 203, and after light distribution by the first light distribution surface 203, the aforementioned light can produce a divergence effect in the circumferential direction of the optical lens, so as to expand the angle covered by the light beam after light distribution by the first light distribution surface 203 in the circumferential direction of the optical lens, based on this, the divergence effect provided by the first light distribution surface 203 for the light makes the light diverge in the circumferential direction of the optical lens 200, so as to ensure that the light emitted by the plurality of light supplementing units 310 can be equivalent to a ring-shaped light supplementing lamp under the action of the first light distribution surface 203.

[0033] More intuitively, as shown, Figure 4 in the embodiment of the present application, the figure of the first light distribution surface 203 cut by a plane perpendicular to the optical axis of the camera module 100 includes a first arc-shaped line segment, and the first arc-shaped line segment protrudes away from the camera module 100, in this case, so that the first light distribution surface 203 can provide a diffusion effect for the light incident from the outer side of the first light distribution surface 203, and the direction of the diffusion effect is the circumferential direction of the optical lens 200.

[0034] The electronic device disclosed by the embodiments of the present application has an optical lens 200 in a closed ring structure as a whole, and the optical lens 200 is arranged outside the camera module 100. The light emitting surface 202 in the optical lens 200 is in a closed circular ring structure, so that the light emitted through the light emitting surface 202 of the optical lens 200 is in a ring structure as a whole, and the center of the light supplementing area and the center of the camera module 100 substantially coincide, so that the light supplementing effect of the electronic device is relatively good, and the shooting effect of the camera module 100 is improved.

[0035] In the embodiments of the present application, the plurality of light supplementing units 310 are distributed along the circumference of the optical lens 200 and are arranged towards the light incident surface 201 of the optical lens 200. In the radial direction of the optical lens 200, the light emitting surface 202 and the first light distribution surface 203 of the optical lens 200 are both located on the inner side of the light incident surface 201, and in the direction of the optical axis of the camera module, the first light distribution surface 203 is located on the side of the light emitting surface 202 close to the light supplementing unit 310, so that the light incident from the light incident surface 201 can be reflected by the first light distribution surface 203, and the reflected light is emitted from the light emitting surface 202 to the outside of the optical lens 200. At the same time, in the electronic device disclosed by the embodiments of the present application, the figure of the first light distribution surface 203 cut by the plane perpendicular to the optical axis of the camera module includes a first arc-shaped line segment, and the first arc-shaped line segment protrudes away from the camera module 100, so that the first light distribution surface 203 can provide diffusion effect for the light incident from the outer side of the first light distribution surface 203 to the first light distribution surface 203 in the circumferential direction of the optical lens 200, so that the light emitted by the plurality of light supplementing units 310 can be light distributed by the first light distribution surface 203, forming a ring-distributed lighting effect.

[0036] As described above, the light incident through the light incident surface 201 can be reflected at the first light distribution surface 203 and directed to the light emitting surface 202. Optionally, the figure of the first light distribution surface 203 cut by the plane passing through the optical axis of the camera module 100 can include a straight line segment, in which case the light distribution density on the light incident side of the first light distribution surface 203 is substantially the same as the light distribution density on the light emitting side of the first light distribution surface 203. In order to maximize the light utilization efficiency of the light supplementing unit 310, in another embodiment of the present application, as shown in FIG. 6, the figure of the first light distribution surface cut by the plane passing through the optical axis of the camera module 100 can include a third arc-shaped line segment, and the third arc-shaped line segment protrudes towards the camera module 100. Figure 5

[0037] ​It should be noted that, since the first light distribution surface 202 provides a reflection function as an inner surface of the optical lens 200, the first light distribution surface 202 is actually concave in a plane of the optical axis of the camera module 100, which enables the first light distribution surface 202 to provide a converging function for the light in the aforementioned plane, so that as much light as possible that enters through the light entrance surface 201 is distributed by the first light distribution surface 202 and reflected to the light exit surface 202. Of course, the specific parameters such as the radius of the arc at any position on the third arc segment can be flexibly selected according to actual conditions, and this is not limited herein.

[0038] As described above, in the electronic device disclosed in the embodiments of the present application, the light supplementing unit 310 is used as the original light source, so that the cost and assembly difficulty can be reduced to a certain extent, and the installation space occupied by the light supplementing unit 310 and the optical lens 200 can be reduced. At the same time, the point-shaped light emitted by the plurality of light supplementing units 310 can be converted into a ring-shaped illumination effect by the optical lens 200, so that the shooting effect of the camera module 100 is relatively good, and since the camera module 100 can be embedded on the inner side of the optical lens 200, the overall thickness of the area where the camera module 100 is located can be reduced.

[0039] In order to further improve the utilization efficiency of the optical lens 200 for the light emitted by the light supplementing unit 310, in the embodiments of the present application, as shown in Figures 3-5 the optical lens 200 can also have a second light distribution surface 204. In the radial direction of the optical lens 200, the second light distribution surface 204 is located on the outer side of the first light distribution surface 203, and the second light distribution surface 204 corresponds to the first light distribution surface 203. At the same time, in the direction of the optical axis of the camera module 100, the second light distribution surface 204 is located on the side away from the light supplementing unit 310. That is, by designing the position of the second light distribution surface 204, the light incident into the optical lens 200 from the light entrance surface 201 can first pass through the second light distribution surface 204, and then be distributed by the second light distribution surface 204 and incident into the first light distribution surface 203. In other words, taking the light exit surface 202 as the uppermost, the light entrance surface 201 can be located below the second light distribution surface 204, in which case, the light entrance surface 201 can be away from the light entrance side of the camera module 100, so that the size of the optical lens 200 in the radial direction can be reduced, and the complexity of the optical path in the optical lens 200 can be reduced, and the utilization and conversion efficiency of the optical lens 200 for light can be improved.

[0040] In addition, the second light distribution surface 204 is a curved line segment, and the curved line segment protrudes away from the camera module 100, so that the second light distribution surface 204 can converge the light incident on the second light distribution surface 204, which is located in the plane perpendicular to the camera module 100, to further improve the utilization rate of the light emitted by the light supplement unit 310. In this case, the light emitted by the light supplement unit 310 is incident on the optical lens through the light entrance surface 201, converges at the second light distribution surface 204 first, and then diverges at the first light distribution surface 203, and finally is emitted out of the optical lens 200 through the light exit surface 202.

[0041] Similarly, for the second light distribution surface 204, since it also serves as a reflection surface, the image of the second light distribution surface 204, which is cut by the plane passing through the optical axis of the camera module 100, can also be a straight line segment. In this case, the second light distribution surface 204 does not have the effect of converging or diverging the light located in the plane passing through the optical axis of the camera module 100, so that the density of the light located in the plane passing through the optical axis of the camera module 100 and on the light entrance side of the second light distribution surface 204 is almost the same as the density of the light located in the plane passing through the optical axis of the camera module 100 and on the light exit side of the second light distribution surface 204.

[0042] In order to further improve the utilization efficiency of the second light distribution surface 204 for light, in another embodiment of the present application, the image of the second light distribution surface 204, which is cut by the plane passing through the optical axis, includes a fourth curved line segment, and the fourth curved line segment protrudes away from the camera module 100. In this case, the light located in the plane passing through the optical axis and incident from different positions on the second light distribution surface 204 can be reflected by the second light distribution surface 204 and propagate toward the first light distribution surface 203, so as to further improve the utilization rate of the light emitted by the light supplement unit 310. Similarly, the curvature and other parameters of the second light distribution surface 204 in different directions can also be selected flexibly according to actual conditions, which are not limited herein.

[0043] As described above, the light exit surface 202 faces the viewfinder area of the camera module 100, and the orientation of the light entrance surface 201 can be selected according to the actual structure of the optical lens 200. More specifically, the light exit surface 202 and the light entrance surface 201 can both be planes, in which case the light exit surface 202 and the light entrance surface 201 can both be perpendicular to the optical axis direction of the camera module 100, and the light exit surface 202 and the first light distribution surface 203 are distributed along the light entrance direction of the camera module 100, and the second light distribution surface 204 and the light entrance surface 201 are also distributed along the light entrance direction of the camera module 100. At the same time, the second light distribution surface 204 is located on the outer side of the first light distribution surface 203, and the two are distributed along the radial direction of the optical lens 200.

[0044] In the above embodiment, the light-out surface 202 is used to enable the optical lens 200 to generate a ring-shaped light supplement effect. To this end, as described above, in the embodiment of the present application, the light-out surface 202 is in a closed circular ring structure. As for the light-in surface 201, the first light distribution surface 203 and the second light distribution surface 204, they can all be in a non-closed ring structure, and the number of the aforementioned three can be made to correspond to the number of the light supplement monomers 310, and in the assembly process, the light supplement monomers 310, the light-in surface 201, the second light distribution surface 204 and the first light distribution surface 203 can be made to correspond one by one. At the same time, by making the first light distribution surface 203 and the second light distribution surface 204 span a preset angle such as 30° in the circumferential direction of the optical lens 200, it can be ensured that the light emitted by the point-shaped light source light supplement monomers 310 can be collected by the corresponding second light distribution surface 204, and a diffusion effect can be generated at the first light distribution surface 203, so that the light is irradiated on the closed circular ring-shaped light-out surface 202, and the optical lens 200 generates a ring-shaped light supplement effect.

[0045] In another embodiment of the present application, at least one of the first light distribution surface 203 and the second light distribution surface 204 can be in a closed ring structure, and further, both of them can be in a closed ring structure, which can reduce the processing difficulty of the entire optical lens 200, and can also reduce the installation difficulty of the optical lens 200, and can also improve the optical effect of the optical lens 200 to a certain extent, and improve the effective utilization rate of the light of the light supplement monomers 310.

[0046] As described above, the optical lens 200 has the first light distribution surface 203 and the second light distribution surface 204, the first light distribution surface 203 is the inner surface of the inner side of the ring of the optical lens 200, and the second light distribution surface 204 is the inner surface of the outer side of the ring of the optical lens 200. Based on this, the light incident from the light-in surface 201 propagates within the optical lens 200 before being emitted from the light-out surface 202, and then, in order to prevent the light from being directly emitted from the first light distribution surface 203 and the second light distribution surface 204 to the outside of the optical lens 200, in one specific embodiment of the present application, the reflection angles of the second arc-shaped segment and the fourth arc-shaped segment can be designed to ensure that the light can be totally reflected at the first light distribution surface 203 and the second light distribution surface 204.

[0047] In another embodiment of the present application, a reflective film can also be provided on the outer wall of the first light distribution surface 203, which can basically prevent the light from being emitted from the first light distribution surface 203 to the outside of the optical lens 200, and can also improve the reflection effect of the first light distribution surface 203 on the light. Optionally, the outer wall of the second light distribution surface 204 is also provided with a reflective film, so as to prevent the light from being emitted from the second light distribution surface 204 to the outside of the optical lens 200, while further improving the reflection effect of the second light distribution surface 204 on the light.

[0048] Specifically, the reflective film can be formed on the outer wall of the optical lens 200 by pasting or the like. In another embodiment of the present application, the reflective film can also be formed on the outer wall of the optical lens 200 by plating or the like. On the one hand, this can improve the fit between the reflective film and the surface of the optical lens 200. On the other hand, it can greatly reduce the thickness of the reflective film, thereby reducing the installation space occupied by the entire electronic device. In addition, by providing the reflective film on the outer wall of the first light distribution surface 203 and the second light distribution surface 204 of the optical lens 200, it can also prevent other devices in the electronic device that are located outside the optical lens 200 from possibly absorbing the light in the optical lens 200, especially black or dark devices.

[0049] In any of the above embodiments of the electronic device disclosed in the present application, a circuit board 510 is also provided, wherein the camera module 100 and the plurality of light supplement units 310 of the electronic device are electrically connected to the circuit board 510. In more detail, the electronic device can further include a housing 520, a frame 530, a support 540, a decorative ring 550, and a lens 560, etc. The display screen and the housing 520 are respectively connected to opposite sides of the frame 530. The battery, the support 540, and the circuit board 510, etc. can be installed between the display screen and the housing 520, and the circuit board 510 can be fixedly installed on the support 540. The support 540 and the frame 530, etc. can form a fixed connection relationship. The housing 520 is provided with a through hole, the decorative ring 550 can be arranged outside the through hole, and the lens 560 is arranged at the through hole and the camera module 100 is arranged towards the lens 560, so that the light outside the electronic device can pass through the lens 560 and be incident into the camera module 100. More specifically, the decorative ring 550 can be fixedly connected to the housing 520, and the decorative ring 550 can be protrudingly arranged outside the housing 520. By fixing the lens 560 at one end of the decorative ring 550 away from the housing 520, the thickness of the independent area where the lens 560 is located can be individually increased, so that the size of the camera module 100 can also be appropriately increased, thereby achieving the purpose of improving the shooting effect of the camera module 100.

[0050] In the process of assembling the electronic device, the camera module 100 and the plurality of light supplement units 310 can be located on the same side of the circuit board 510. More specifically, the camera module 100 and the light supplement units 310 can be mounted on the circuit board 510 by welding, and during the welding process, the camera module 100 and the light supplement units 310 can form an electrical connection relationship with the circuit board 510. Of course, in other embodiments of the present application, the camera module 100 and the flexible circuit board 320 can form an electrical connection relationship with the circuit board 510, and the plurality of light supplement units 310 can be mounted on the same flexible circuit board 320, and the flexible circuit board 320 can make the plurality of light supplement units 310 form an electrical connection relationship with the circuit board 510, which can greatly reduce the assembly efficiency of the plurality of light supplement units 310. Of course,

[0051] As described above, the electronic device includes the camera module 100, the optical lens 200, and the plurality of light supplement units 310. Generally, due to the relatively large size of the camera module 100, and the camera module 100 usually includes a lens barrel arranged on the outer side, the lens barrel and the like can be used to fix the camera module 100 with the circuit board 510, the housing 520 or the frame 530 and the like of the electronic device, so that the camera module 100 completes the stable assembly process. As for the optical lens 200 and the plurality of light supplement units 310, the area of the optical lens 200 that does not provide optical function can be fixed with the circuit board 510 or the housing 520 and the like by means such as bonding, and the light supplement units 310 can be fixed on the circuit board 510 by welding and the like.

[0052] In another embodiment of the present application, as shown in Figure 1 and Figure 2 The electronic device further includes a limiting piece 400, which is arranged on the side of the circuit board 510 facing the camera module 100, and the limiting piece 400 includes a limiting edge 410 and a limiting body 420 fixedly connected, and more specifically, the two can be formed in one piece. The limiting body 420 has a limiting groove 421 on the side facing the lens 560, that is, the limiting groove 421 is recessed from the surface of the limiting body 420 on the side facing the lens 560, and the optical lens 200 is mounted in the limiting groove 421. Of course, the size and shape of the limiting groove 421 correspond to the size and shape of the optical lens 200, and more specifically, the limiting groove 421 is in the form of a cylindrical groove.

[0053] Based on this, in the assembly process of the electronic device, the limiting edge 410 can be relatively fixed with the shell 520 in the optical axis direction of the camera module 100. For example, the limiting edge can be fixedly connected with the shell 520 by bonding or the like, or the limiting edge 410 can be clamped between the inner surface of the shell 520 and the support 540. Of course, in this case, the limiting edge 410 needs to be sealed, for example, sealing glue can be applied between the outer edge of the part of the limiting piece 400 extending into the through hole of the shell 520 and the inner edge of the through hole, or sealing foam or the like can be arranged between the decorative ring 550 and the shell 520 and between the decorative ring 550 and the lens 560.

[0054] At the same time, in the optical axis direction of the camera module 100, the optical lens 200 can be clamped between the lens 560 and the groove bottom of the limiting groove 421, so that the optical lens 200 and other devices such as the shell 520 of the electronic device form a reliable fixed assembly relationship, and the light distribution effect provided by the optical lens 200 is ensured to be stable. In the case of adopting the technical solution disclosed in the embodiment, the optical lens 200 and the inner wall of the limiting groove 421 of the limiting main body 420 can be further bonded by double-sided adhesive or the like to form a bonded fixed relationship, thereby further improving the assembly stability of the optical lens 200.

[0055] In the above embodiment, the optical lens 200 is installed in the limiting groove 421 of the limiting piece 400. In order to ensure that the light emitted by the plurality of light supplement monomers 310 can still normally enter the optical lens 200, the limiting groove 421 is further provided with a light passing hole 422, and the plurality of light supplement monomers 310 are arranged opposite to the light passing hole 422, so that the light emitted by the light supplement monomers 310 can enter the limiting groove 421 through the light passing hole 422 and be distributed by the optical lens 200. Similarly, the position of the light passing hole 422 is also related to the specific structure of the optical lens 200, that is, the relative position relationship between the light supplement monomers 310 and the optical lens 200. Optionally, the light passing hole 422 can be arranged on the side wall of the limiting groove 421, in which case the light supplement monomers 310 can be located outside the side of the limiting groove 421.

[0056] Of course, the number of light passing holes 422 can be one, and the angle of the light passing hole 422 across the circumference of the optical lens 200 can cover the range where the plurality of light supplement monomers 310 are located, so as to ensure that the light emitted by the plurality of light supplement monomers 310 can pass through the light passing hole 422 and enter the optical lens 200. Of course, in order to ensure that the limiting body still has a reliable limiting effect, the angle of the light passing hole 422 across the circumference of the optical lens 200 needs to be less than 360°.

[0057] In order to further improve the assembly stability of the optical lens 200, in another embodiment of the present application, the optical lens 200 can be made to include the light distribution part 210 and a plurality of limiting parts 220 connected to each other, wherein the light distribution part 210 has the light emitting surface 202 and the first light distribution surface 203, and the plurality of limiting parts 220 each have the light entering surface 201. In order to ensure that the light entering through the light entering surface 201 of the limiting part 220 can be transmitted out through the light emitting surface 202, in the optical lens 200 disclosed in the embodiment of the present application, the light distribution part 210 also has a second light distribution surface 204, which makes the light rays incident into the optical lens 200 along the optical axis direction of the camera module 100, after being sequentially light-distributed through the second light distribution surface 204 and the first light distribution surface 203, still can be transmitted out to the outside of the optical lens 200 along the aforementioned optical axis direction through the light emitting surface 202. In addition, from the direction of the light entering surface 201 of the limiting part 220 away from the light distribution part 210 to the other end surface of the limiting part 220 close to the light distribution part 210, the spacing between the two opposite sides of each limiting part 220 along the circumferential direction of the optical lens 200 can gradually increase, so as to increase the propagation range of the light incident from the light entering surface 201. Of course, the plurality of limiting parts 220 can be formed in an integral molding manner with the light distribution part 210, so as to reduce the processing difficulty of the optical lens 200.

[0058] Wherein the plurality of light supplementing units 310 are arranged in one-to-one correspondence with the plurality of limiting parts 220, the number of the light transmission holes 422 can also be multiple, and are spaced apart along the circumferential direction of the optical lens 200. By making the plurality of limiting parts 220 extend into the plurality of light transmission holes 422 in one-to-one correspondence, the plurality of light supplementing units 310 can also be arranged in one-to-one correspondence with the plurality of light transmission holes 422, thereby reducing the angle range covered by each light transmission hole 422 in the above-mentioned circumferential direction, and greatly improving the structural strength of the part of the limiting member 400 where the limiting groove 421 is located, so as to ensure that the limiting stability of the optical lens 200 in the optical axis direction of the camera module 100 is relatively high.

[0059] At the same time, in the embodiment of the present application, by making the plurality of limiting parts 220 extend into the plurality of light transmission holes 422 in one-to-one correspondence, the optical lens 200 can also form a reliable limiting cooperation relationship with the limiting member 400 in the circumferential direction of the optical lens 200, thereby further improving the assembly stability, light distribution reliability and light distribution consistency of the optical lens 200. Of course, in the embodiment of the present application, the part of the optical lens 200 limited by the groove bottom of the limiting groove 421 is the surface of the light distribution part 210 away from the light emitting surface 202.

[0060] As described above, the lens 560 can be mounted at the far end of the decorative ring 550 which is outwardly protruding relative to the shell 520, in this case, a part of each of the limiting member 400 and the camera module 100 can be located outside the shell 520 and inside the lens 560, and accordingly, at least a part of the optical lens 200 is also located outside the shell 520, in order to ensure that the light emitting area of the optical lens 200 can be concentrated at the light emitting surface 202, in the embodiment of the present application, the first light shielding foam 610 can be arranged between the end face of the limiting body 420 close to the lens 560 and the lens 560, in the radial direction of the optical lens 200, the first light shielding foam 610 can extend from the outer edge of the lens 560 to the outer edge of the light emitting surface 202, and the first light shielding foam 610 is arranged outside the light emitting surface 202, which makes the area between the outer edge of the light emitting surface 202 and the outer edge of the lens 560 in the optical lens 200 can be covered by the first light shielding foam 610, preventing the light leakage from occurring in the aforementioned area, on the one hand, preventing stray light from interfering with the shooting effect of the camera module 100, on the other hand, it can also improve the precision of the electronic device, and thus improve the user experience.

[0061] In order to further prevent the light in the optical lens 200 from interfering with the shooting process of the camera module 100, in one specific embodiment of the present application, the bracket 540 can include a body portion and a surrounding portion 542 connected to each other, wherein the circuit board 510 and the plurality of light supplement units 310 can be mounted on the body portion, the body portion is fixedly connected with the shell 520, and the surrounding portion 542 is fixedly connected with the body portion, of course, the two can be formed by integral molding during processing. Wherein, the surrounding portion 542 surrounds the camera module 100, that is, the surrounding portion 542 surrounds the camera module 100, at the same time, the surrounding portion 542 and the lens 560 are provided with the second light shielding foam 620, the second light shielding foam 620 is arranged outside the camera module 100, and the optical lens 200 is arranged outside the second light shielding foam 620. In this case, the camera module 100 and the optical lens 200 can be isolated from each other by the surrounding portion 542, the body portion 541 and the second light shielding foam 620, and thus the light in the optical lens 200 can be prevented from directly entering the camera module 100, and adversely affecting the shooting effect of the camera module 100.
