Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to an electronic equipment. Background Art

[0002] The camera module is an important component of electronic devices such as mobile phones, and in order to improve the shooting effect, the camera module is usually equipped with a flash. Since the common high-current instantaneous flash of small size is quite different from the fill light effect of continuous natural light, resulting in poor realism of the captured image, more and more manufacturers have begun to use ring fill lights. At present, the optical design of the ring fill light usually includes two types. One is the ring arrangement of the light chain, but due to its relatively large overall volume, it is not conducive to products with strict space requirements such as mobile phones; the other includes a conical surface light distribution cover, which designs the structure of the conical surface so that the light emitted by the fill light unit located in the center of the light distribution cover can be emitted in a ring shape. However, since the fill light unit of this fill light structure needs to be located in the center of the light distribution cover, the camera module can only be installed below or to the side of the light distribution cover, which has an adverse effect on the thickness of the electronic device. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide an electronic device to solve the problem that the current ring fill lights occupy a large assembly space in the electronic device.

[0004] An embodiment of the present application discloses an electronic device, which includes a camera module, an optical lens and a plurality of fill-light monomers, wherein the optical lens is arranged circumferentially outside the camera module, the optical lens has a light incident surface, a light emitting surface and a first light distribution surface, and the plurality of fill-light monomers are distributed along the circumference of the optical lens, and are all arranged toward the light incident surface; in the radial direction of the optical lens, the light emitting surface and the first light distribution surface are both located on the inner side of the light incident surface; the light emitting surface is arranged toward the light incident side of the camera module, and the light emitting surface is a closed circular ring structure; in the direction where the optical axis of the camera module is located, the first light distribution surface is located on the side of the light emitting surface close to the fill-light monomer; a figure obtained by cutting the first light distribution surface by a plane perpendicular to the optical axis of the camera module includes a first arc segment, and the first arc segment protrudes in a direction away from the camera module.

[0005] An embodiment of the present application discloses an electronic device, wherein the optical lens is a closed ring structure as a whole, and the optical lens is arranged around the outside of a camera module. The light emitting surface of the optical lens is a closed circular ring structure, which makes the light emitted through the light emitting surface of the optical lens annular as a whole, and the center of the fill light area basically coincides with the center of the camera module, which makes the fill light effect of the electronic device relatively good and improves the shooting effect of the camera module.

[0006] Among them, a plurality of fill light monomers are distributed along the circumference of the optical lens, and are all arranged toward the light incident surface of the optical lens. In the radial direction of the optical lens, the light exit surface and the first light distribution surface of the optical lens are both located on the inner side of the light incident surface, and in the direction of the optical axis of the camera module, the first light distribution surface is located on the side of the light exit surface close to the fill light monomer, so that the light incident from the light incident surface can be reflected by the first light distribution surface, so that the reflected light is emitted from the light exit surface to the outside of the optical lens. At the same time, in the electronic device disclosed in the embodiment of the present application, the figure obtained by cutting the first light distribution surface by a plane perpendicular to the optical axis of the camera module includes a first arc segment, and the first arc segment protrudes in the direction away from the camera module, so that the first light distribution surface can provide diffusion effect for the light incident from the outside of the first light distribution surface to the first light distribution surface in the circumferential direction of the optical lens, so that the light emitted by the point light sources of the plurality of fill light monomers can be distributed by the first light distribution surface, forming a ring-shaped distribution lighting effect.

DETAILED DESCRIPTION

[0009] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0011] The present application embodiment discloses an electronic device, which may be a mobile phone or a tablet computer. Figure 1-Figure 6 As shown, the electronic device includes a camera module 100, an optical lens 200 and a plurality of fill light units 310.

[0012] Among them, the camera module 100 can generally include devices such as a photosensitive chip and a lens group. The optical lens 200 is used to provide light distribution for the fill light monomer 310. The fill light monomer 310 is a single-body fill light with a constant-on function. The parameters of multiple fill light monomers 310 can be the same, or fill light monomers 310 with different parameters can be arranged at different positions of the optical lens 200 according to actual conditions such as the arrangement position.

[0013] The optical lens 200 is a closed ring structure as a whole, that is, the optical lens 200 has a closed ring optical surface, but it does not mean that any optical surface in the optical lens 200 is a closed ring structure. In detail, in the embodiment of the present application, the light emitting surface 202 of the optical lens 200 is a closed circular ring structure, so that the light emitted by the fill light monomer 310 can present a ring-shaped light source form after being emitted from the light emitting surface 202 of the optical lens 200.

[0014] During the assembly of the electronic device, since the optical lens 200 is a closed ring structure, the optical lens 200 can be arranged around the outside of the camera module 100. Based on this, 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 fill light center of the optical lens 200 can overlap or substantially overlap with the shooting center of the camera module 100, and the light emitting surface 202 of the optical lens 200 is a closed circular ring structure, thereby making the fill light effect of the optical lens 200 relatively good, so as to improve the shooting effect of the camera module 100.

[0015] As mentioned above, the optical lens 200 has a light emitting 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 an embodiment of the present application, the light emitting surface 202 is arranged toward the light incident side of the camera module 100, so that the light emitted through the light emitting surface 202 can be irradiated on the light incident side of the camera module 100, that is, the area to be photographed by the camera module 100. Specifically, the light emitting surface 202 can be a curved surface, for example, the light emitting surface 202 can be a convex surface, in which case, the light emitting surface 202 can provide a divergent effect for the light. In other embodiments of the present application, the light emitting surface 202 is a plane, and the light emitting surface 202 is perpendicular to the optical axis direction of the camera module 100, so that the light after light distribution by the first light distribution surface 203 can be vertically emitted from the light emitting surface 202.

[0016] Correspondingly, the optical lens 200 also has a light incident surface 201, and each fill-light monomer 310 is arranged toward the light incident surface 201, so that the light emitted by each fill-light monomer 310 can be incident from the light incident surface 201 into the optical lens 200. Specifically, in the radial direction of the optical lens 200, the fill-light monomer 310 can be arranged outside the light incident surface 201, so that when the fill-light monomer 310 is working, it is ensured that the light emitted by the fill-light monomer 310 can enter the optical lens 200 through the light incident surface 201 and be distributed by the optical lens 200, that is, the direction of the light incident surface 201 is related to the parameters such as the specific structure of the optical lens 200. For example, when the light emitted by the fill light monomer 310 is directly transmitted toward the first light distribution surface 203 after being incident from the light incident surface 201, the light incident surface 201 and the fill light monomer 310 can both be located outside the optical lens 200. Correspondingly, when the optical lens 200 includes other light distribution surfaces, the light incident surface 201 and the fill light monomer 310 can be correspondingly arranged at other positions of the optical lens 200. In addition, the light incident surface 201 can also be a curved surface, such as a concave surface, so as to provide a convergence effect on the light and improve the utilization rate of the fill light monomer 310. In other embodiments of the present application, the light incident surface 201 can also be a plane to reduce the difficulty of processing and designing the entire optical lens 200.

[0017] At the same time, in order to improve the fill light effect of electronic equipment, especially the fill light uniformity of the optical lens 200 in its own circumferential direction, multiple fill light monomers 310 can be distributed along the circumference of the optical lens 200, so that different fill light monomers 310 can provide light at different positions of the optical lens 200, and after the light distribution and divergence of the optical lens 200, they complement each other to form a ring-shaped lighting effect. More specifically, multiple fill light monomers 310 are evenly and spaced apart in the circumferential direction of the optical lens 200. Of course, the number of fill light monomers 310 can be specifically two. In order to maximize the fill light effect of the electronic device, in a specific embodiment of the present application, the number of fill light monomers 310 can be equal to or greater than 3. At the same time, in order to prevent a significant increase in assembly difficulty and cost due to a relatively large number of fill light monomers 310, in the present application, an upper limit on the number of fill light monomers 310 can be set, which can be specifically 6, 8 or 10, etc. Since the number of fill light monomers 310 in the electronic device disclosed in the embodiment of the present application is less than or much less than the number of fill light monomers 310 in the common chain-type ring fill light, it can still be ensured that the cost of the electronic device disclosed in the embodiment of the present application is still relatively low, the required assembly space and structural design difficulty are relatively small, and the heat dissipation is better.

[0018] As described above, the optical lens 200 is used to convert the divergent light emitted by the plurality of fill-in light monomers 310 into a ring-shaped fill-in light effect. For this purpose, in the embodiment of the present application, Figure 3-Figure 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 emitting surface 202 and the first light distribution surface 203 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 close to the fill light monomer 310. In layman's terms, generally speaking, it can be considered that the light emitting 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 incident surface 201 is located on the outer side of the ring of the optical lens 200. At the same time, the light emitting surface 202 is located on the outer end surface of the optical lens 200, and the light incident surface 201 is located on the inner end surface of the optical lens.

[0019] In this case, since the optical lens 200 is annular in structure as a whole, and the first light distribution surface 203 is located inside the ring of the optical lens 200, the first light distribution surface 203 can actually be used as the inner surface of the optical lens 200 to provide reflection. Figure 5 As shown, light incident from the light incident surface 201 located outside the ring of the optical lens 200 can be reflected at the first light distribution surface 203 and directed toward the light emitting surface 202 located outside thereof, so that the light is emitted from the light emitting surface 202 to the outside of the optical lens 200 .

[0020] Furthermore, in the embodiment of the present application, the surface shape of the first light distribution surface 203 is designed so that the first light distribution surface 203 can provide a divergent effect for light, and the divergent direction is specifically the circumferential direction of the optical lens 200. More intuitively speaking, a beam of light is incident on a partial area of ​​the first light distribution surface 203, and after being distributed by the first light distribution surface 203, the aforementioned light can produce a divergent effect in the circumferential direction of the optical lens, thereby expanding the angle covered by the light beam after being distributed by the first light distribution surface 203 in the circumferential direction of the optical lens. Based on this, the divergent effect provided by the first light distribution surface 203 for the light is utilized to make the light diverge in the circumferential direction of the optical lens 200, so as to ensure that the light emitted by the multiple fill light monomers 310 can be equivalent to a ring fill light under the action of the first light distribution surface 203.

[0021] More intuitively, if Figure 4 As shown, in the embodiment of the present application, the figure obtained by cutting the first light distribution surface 203 by a plane perpendicular to the optical axis of the camera module 100 includes a first arc segment, and the first arc segment protrudes in the direction away from the camera module 100. In this case, the first light distribution surface 203 can provide a diffusion effect for light incident from the outside of the first light distribution surface 203, and the direction of the diffusion effect is the circumferential direction of the optical lens 200.

[0022] An embodiment of the present application discloses an electronic device, wherein the optical lens 200 is a closed ring structure as a whole, and the optical lens 200 is arranged around the outside of the camera module 100, and the light output surface 202 in the optical lens 200 is a closed circular ring structure, which makes the light emitted through the light output surface 202 of the optical lens 200 to be annular as a whole, and the center of the fill light area basically coincides with the center of the camera module 100, which makes the fill light effect of the electronic device relatively good, thereby improving the shooting effect of the camera module 100.

[0023] Among them, multiple fill light monomers 310 are distributed along the circumference of the optical lens 200, and are all set towards the light incident surface 201 of the optical lens 200. In the radial direction of the optical lens 200, the light exit 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 exit surface 202 close to the fill light monomer 310, so that the light incident from the light incident surface 201 can be reflected by the first light distribution surface 203, so that the reflected light is emitted from the light exit surface 202 to the outside of the optical lens 200. At the same time, in the electronic device disclosed in the embodiment of the present application, the figure obtained by cutting the first light distribution surface 203 by a plane perpendicular to the optical axis of the camera module includes a first arc segment, and the first arc segment protrudes in the direction away from the camera module 100, so that the first light distribution surface 203 can provide a diffusion effect for the light incident from the outside 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 multiple fill light monomers 310, such as point light sources, can be distributed by the first light distribution surface 203, forming a ring-shaped distribution lighting effect.

[0024] As described above, light incident through the light incident surface 201 may be reflected at the first light distribution surface 203 and emitted toward the light emitting surface 202. Optionally, the graph of the first light distribution surface 203 cut by the plane passing through the optical axis of the camera module 100 may include a straight line segment. In this 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 fill light unit 310, in another embodiment of the present application, as Figure 5 As shown, the figure obtained by cutting the first light distribution surface by the plane passing through the optical axis of the camera module 100 can include a third arc segment, and the third arc segment protrudes toward the direction approaching the camera module 100.

[0025] It should be noted that, since the first light distribution surface 202 is used as the inner surface of the optical lens 200 to provide a reflective effect, in the plane passing through the optical axis of the camera module 100, the first light distribution surface 202 is actually a concave structure, which enables the first light distribution surface 202 to provide a convergence effect for the light in the aforementioned plane, so that the light incident through the light incident surface 201 is distributed by the first light distribution surface 202 as much as possible, and is reflected to the light exiting surface 202. Of course, the specific parameters such as the curvature at any position on the third arc segment can be flexibly selected according to actual conditions, and this article does not limit this.

[0026] As described above, in the electronic device disclosed in the embodiment of the present application, a fill light monomer 310 is used as the original light source, which can reduce the cost and assembly difficulty to a certain extent, and can reduce the installation space occupied by the fill light monomer 310 and the optical lens 200; at the same time, the optical lens 200 can be used to convert the point light emitted by multiple fill light monomers 310 into a ring-shaped lighting effect, thereby ensuring that the shooting effect of the camera module 100 is relatively good, and because 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.

[0027] In order to further improve the utilization efficiency of the optical lens 200 for the light emitted by the fill light monomer 310, in the embodiment of the present application, Figure 3-Figure 5 As shown, the optical lens 200 may 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 outside 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 of the light incident surface 201 away from the fill light monomer 310. That is, by designing the position of the second light distribution surface 204, the light incident from the light incident surface 201 to the optical lens 200 can first pass through the second light distribution surface 204, and then, after being distributed by the second light distribution surface 204, it can be incident on the first light distribution surface 203. In layman's terms, with the light emitting surface 202 being located at the top, the light incident surface 201 can be located below the second light distribution surface 204. In this case, the light incident surface 201 can be turned away from the light incident side of the camera module 100, thereby reducing the radial size of the optical lens 200 and reducing the complexity of the optical path in the optical lens 200, thereby improving the efficiency of light utilization and conversion by the optical lens 200.

[0028] Furthermore, the second light distribution surface 204 is cut by a plane perpendicular to the camera module 100, and the second light distribution surface 204 includes a second arc segment, and the second arc segment protrudes in a direction away from the camera module 100, so that the second light distribution surface 204 can provide a convergence effect for the light that is located in a plane perpendicular to the camera module 100 and incident on the second light distribution surface 204, so as to further improve the utilization rate of the light emitted by the fill light monomer 310. In this case, the light emitted by the fill light monomer 310 enters the optical lens through the light incident surface 201, first converges at the second light distribution surface 204, then diverges at the first light distribution surface 203, and finally emits from the light exit surface 202 to the outside of the optical lens 200.

[0029] Similarly, for the second light distribution surface 204, since it also serves as a reflective surface, the image of the second light distribution surface 204 intercepted by the plane of the optical axis of the camera module 100 can also be a straight line segment. In this case, the second light distribution surface 204 has no convergence or divergence effect on the light located in the plane of the optical axis of the camera module 100, so that the density of the light located in the plane of the optical axis of the camera module 100 and on the light incident side of the second light distribution surface 204 is almost the same as the density of the light located in the aforementioned plane and on the light exit side of the second light distribution surface 204.

[0030] In order to further improve the efficiency of light utilization by the second light distribution surface 204, in another embodiment of the present application, the figure obtained by cutting the second light distribution surface 204 by the plane passing through the optical axis includes a fourth arc segment, and the fourth arc segment protrudes in the direction away from the camera module 100. In this case, basically, the light rays located in the plane where the optical axis is located 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 of the light emitted by the fill light monomer 310. Similarly, the parameters such as the curvature of the second light distribution surface 204 in different directions can also be flexibly selected according to actual conditions, and this document does not limit this.

[0031] As described above, the light emitting surface 202 faces the viewing area of ​​the camera module 100, and the direction of the light incident surface 201 can be selected according to the actual structure of the optical lens 200. More specifically, the light emitting surface 202 and the light incident surface 201 can be both planes. In this case, the light emitting surface 202 and the light incident surface 201 can be perpendicular to the optical axis direction of the camera module 100, and the light emitting surface 202 and the first light distribution surface 203 are distributed along the light incident direction of the camera module 100, and the second light distribution surface 204 and the light incident surface 201 are also distributed along the light incident direction of the camera module 100. At the same time, the second light distribution surface 204 is located outside the first light distribution surface 203, and the two are distributed along the radial direction of the optical lens 200.

[0032] In the above embodiment, the light emitting surface 202 is used to enable the optical lens 200 to produce a ring-shaped fill light effect. For this reason, as mentioned above, in the embodiment of the present application, the light emitting surface 202 is a closed circular ring structure. As for the light incident surface 201, the first light distribution surface 203 and the second light distribution surface 204, they can all be non-closed ring structures, and the number of the above three can be made to correspond to the number of fill light monomers 310. In the assembly process, the fill light monomers 310, the light incident surface 201, the second light distribution surface 204 and the first light distribution surface 203 can be made to correspond one to one. At the same time, by making the first light distribution surface 203 and the second light distribution surface 204 cross 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 fill light monomer 310 of the point light source can be converged by the corresponding second light distribution surface 204, and a diffusion effect is generated at the first light distribution surface 203, so that the light is irradiated on the closed circular ring-shaped light output surface 202, and the optical lens 200 produces a ring-shaped fill light effect.

[0033] 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 a closed ring structure. Furthermore, both of them can be closed ring structures. On the one hand, the processing difficulty of the entire optical lens 200 can be reduced. On the other hand, the installation difficulty of the optical lens 200 can be reduced. The optical effect of the optical lens 200 can be improved to a certain extent, and the effective utilization rate of the light of the fill light monomer 310 can be improved.

[0034] As described above, the optical lens 200 has a first light distribution surface 203 and a second light distribution surface 204, and 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 incident surface 201 propagates within the optical lens 200 before being emitted from the light emitting surface 202. Furthermore, 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 a specific embodiment of the present application, the reflection angles of the second arc segment and the fourth arc segment can be designed to ensure that the light can be fully reflected at the first light distribution surface 203 and the second light distribution surface 204 as much as possible.

[0035] In another embodiment of the present application, a reflective film may be provided on the outer wall of the first light distribution surface 203, which can basically prevent light from being emitted from the first light distribution surface 203 to the outside of the optical lens 200, and can also improve the light reflection effect of the first light distribution surface 203. Optionally, a reflective film is also provided on the outer wall of the second light distribution surface 204, so as to prevent light from being emitted from the second light distribution surface 204 to the outside of the optical lens 200, and further improve the light reflection effect of the second light distribution surface 204.

[0036] 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 be formed on the outer wall of the optical lens 200 by coating or the like. On the one hand, the degree of adhesion between the reflective film and the surface of the optical lens 200 can be improved. On the other hand, the thickness of the reflective film can be greatly reduced, 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 is also possible to prevent other devices in the electronic device located outside the optical lens 200 from absorbing the light in the optical lens 200, especially black or dark devices.

[0037] In the electronic device disclosed in any of the above embodiments of the present application, a circuit board 510 is also provided, wherein the camera module 100 and the plurality of fill light monomers 310 of the electronic device are electrically connected to the circuit board 510. In more detail, the electronic device may further include a housing 520, a frame 530, a bracket 540, a decorative ring 550, a lens 560, etc., wherein the display screen and the housing 520 are respectively connected to opposite sides of the frame 530, and devices such as a battery, a bracket 540 and a circuit board 510 may be installed between the display screen and the housing 520, and the circuit board 510 may be fixedly installed on the bracket 540, and the bracket 540 and the frame 530 may form a fixed connection relationship; a through hole is provided on the housing 520, the decorative ring 550 may be arranged outside the through hole, the lens 560 is blocked and arranged at the through hole, and the camera module 100 is arranged toward the lens 560, so that light outside the electronic device can pass through the lens 560 and enter the camera module 100. More specifically, the decorative ring 550 can be fixedly connected to the shell 520, and the decorative ring 550 can be protruded outside the shell 520. By fixing the lens 560 at one end of the decorative ring 550 away from the shell 520, the thickness of the independent area where the lens 560 is located can be increased separately, 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.

[0038] During the process of assembling the electronic device, the camera module 100 and the multiple fill light monomers 310 can be located on the same side of the circuit board 510. More specifically, the camera module 100 and the fill light monomers 310 can be installed on the circuit board 510 by welding. During the welding process, the camera module 100 and the fill light monomers 310 can be electrically connected to the circuit board 510. Of course, in other embodiments of the present application, devices such as a flexible circuit board 320 can also be used to make the camera module 100 and the flexible circuit board 320 electrically connected to the circuit board 510, and multiple fill light monomers 310 can be installed on the same flexible circuit board 320. By using the flexible circuit board 320, multiple fill light monomers 310 can be electrically connected to the circuit board 510 together, which can greatly reduce the assembly efficiency of multiple fill light monomers 310. Of course, As described above, the electronic device includes a camera module 100, an optical lens 200, and a plurality of fill light monomers 310. Generally, since the camera module 100 is relatively large in size and the camera module 100 generally includes a lens barrel disposed on the outside, the camera module 100 and components such as a circuit board 510, a housing 520, or a frame 530 of the electronic device can be fixed to each other by using components such as a lens barrel, so that the camera module 100 completes a stable assembly process. As for the optical lens 200 and the plurality of fill light monomers 310, the region of the optical lens 200 that does not provide an optical effect can be fixed to components such as a circuit board 510 or a housing 520 by means such as bonding, and the fill light monomers 310 can be fixed to the circuit board 510 by means such as welding.

[0039] In another embodiment of the present application, Figure 1 and Figure 2 As shown, the electronic device also includes a limiter 400, which is arranged on the side of the circuit board 510 facing the camera module 100, and the limiter 400 includes a fixedly connected limit edge 410 and a limiter body 420, more specifically, the two can be formed in an integrated manner. Among them, a limiter groove 421 is provided on the side of the limiter body 420 facing the lens 560, that is, the limiter groove 421 is formed by a concave surface of the side of the limiter body 420 facing the lens 560, and the optical lens 200 is installed in the limiter groove 421. Of course, the size and shape of the limiter groove 421 correspond to the size and shape of the optical lens 200. More specifically, the limiter groove 421 is a cylindrical groove structure.

[0040] Based on this, during the assembly process of the electronic device, the limiting edge 410 and the shell 520 can be relatively fixed in the optical axis direction of the camera module 100. For example, the limiting edge and the shell 520 can be fixedly connected by bonding or other means, or the limiting edge 410 can be clamped between the inner surface of the shell 520 and the bracket 540. Of course, in this case, the limiting edge 410 needs to be sealed. For example, sealant can be applied between the outer edge of the part of the limiting member 400 that extends into the through hole of the shell 520 and the inner edge of the through hole, or sealing foam or other devices can be provided between the decorative ring 550 and the shell 520, and between the decorative ring 550 and the lens 560.

[0041] At the same time, in the optical axis direction of the camera module 100, the optical lens 200 can be sandwiched between the lens 560 and the bottom of the limiting groove 421, so that the optical lens 200 and other components such as the housing 520 of the electronic device form a reliable fixed assembly relationship, ensuring that the light distribution effect provided by the optical lens 200 is relatively stable. In the case of adopting the technical solution disclosed in this embodiment, the optical lens 200 can also be further bonded and fixed to the inner wall of the limiting groove 421 of the limiting body 420 by adhesives such as double-sided tape, thereby further improving the assembly stability of the optical lens 200.

[0042] In the above embodiment, the optical lens 200 is installed in the limiting groove 421 of the limiting member 400. In order to ensure that the light emitted by the plurality of fill-light monomers 310 can still be normally incident on the optical lens 200, the limiting groove 421 is also provided with a light-through hole 422, and the plurality of fill-light monomers 310 are arranged opposite to the light-through hole 422, so that the light emitted by the fill-light monomers 310 can enter the limiting groove 421 through the light-through hole 422 and be matched by the optical lens 200. Similarly, the position of the light-through hole 422 is also related to the specific structure of the optical lens 200, that is, the relative position relationship between the fill-light monomers 310 and the optical lens 200. Optionally, the light-through hole 422 can be arranged on the side wall of the limiting groove 421. In this case, the fill-light monomers 310 can be located outside the side of the limiting groove 421.

[0043] Of course, the number of the light-through hole 422 can be one, and by making the angle of the light-through hole 422 in the circumferential direction of the optical lens 200 cover the range where the multiple light-filling monomers 310 are located, it can be ensured that the light emitted by the multiple light-filling monomers 310 can pass through the light-through hole 422 and enter the optical lens 200. Of course, in order to ensure that the limiting body still has a reliable limiting function, the angle of the light-through hole 422 in the circumferential direction of the optical lens 200 needs to be less than 360°.

[0044] In order to further improve the assembly stability of the optical lens 200, in another embodiment of the present application, the optical lens 200 may include a light distribution part 210 and a plurality of limiting parts 220 that are interconnected, wherein the light distribution part 210 has a light emitting surface 202 and a first light distribution surface 203, and the plurality of limiting parts 220 all have a light incident surface 201. At the same time, in order to ensure that the light incident through the light incident surface 201 of the limiting part 220 can be transmitted 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, so that the light incident into the optical lens 200 along the optical axis direction of the camera module 100 can still be transmitted to the outside of the optical lens 200 through the light emitting surface 202 along the aforementioned optical axis direction after being sequentially distributed through the second light distribution surface 204 and the first light distribution surface 203. In addition, in the direction from the limiting portion 220 away from the light incident surface 201 of the light distribution portion 210 to the other end surface of the limiting portion 220 close to the light distribution portion 210, the distance between the two side surfaces opposite to each other along the circumference of the optical lens 200 in each limiting portion 220 can be gradually increased to increase the propagation range of the light incident from the light incident surface 201. Of course, multiple limiting portions 220 can be formed in an integral manner with the light distribution portion 210 to reduce the difficulty of processing the optical lens 200.

[0045] Among them, multiple fill-light monomers 310 are arranged in one-to-one correspondence with multiple limiting parts 220, and the number of light-through holes 422 can also be multiple, and are distributed at intervals along the circumference of the optical lens 200. By making multiple limiting parts 220 extend into the multiple light-through holes 422 in one-to-one correspondence, multiple fill-light monomers 310 can also be arranged in one-to-one correspondence with multiple light-through holes 422, thereby reducing the angle range spanned by each light-through 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, thereby ensuring that the limiting stability of the optical lens 200 in the optical axis direction of the camera module 100 is relatively high.

[0046] At the same time, in the embodiment of the present application, by making the multiple limiting parts 220 extend into the multiple light holes 422 in a one-to-one correspondence, the optical lens 200 can also form a reliable limiting matching 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 portion of the optical lens 200 that is mutually limited with the bottom of the limiting groove 421 is the surface of the light distribution part 210 away from the light emitting surface 202.

[0047] As described above, the lens 560 can be installed at the far end of the decorative ring 550 that protrudes outward from the shell 520. In this case, a portion of the limiter 400 and the camera module 100 can be located on the outside of the shell 520 and on the inside of the lens 560. Correspondingly, at least a portion of the optical lens 200 is also located on the outside of the shell 520. In order to ensure that the light emitting area of ​​the optical lens 200 can be concentrated on the light emitting surface 202, in the embodiment of the present application, a first light-shielding bubble can be sandwiched between the end face of the limiter body 420 close to the lens 560 and the lens 560. Cotton 610, 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 around the light-emitting surface 202, so that 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 light leakage from occurring in the aforementioned area. On the one hand, it prevents stray light from interfering with the shooting effect of the camera module 100, and on the other hand, it can also improve the precision of the electronic device, thereby improving the user experience.

[0048] In order to further prevent the light in the optical lens 200 from interfering with the shooting process of the camera module 100, in a specific embodiment of the present application, the bracket 540 can include a main body portion and a surrounding portion 542 that are connected to each other, wherein the circuit board 510 and the plurality of fill light units 310 can be installed in the main body portion, the main body portion is fixedly connected to the shell 520, and the surrounding portion 542 is fixedly connected to the main body portion. Of course, the two can be formed in an integrated manner during the processing process. The surrounding portion 542 is arranged around the camera module 100, that is, the surrounding portion 542 surrounds the outside of the camera module 100. At the same time, the surrounding portion 542 and the lens 560 bracket 540 are sandwiched with a second light-shielding foam 620, the second light-shielding foam 620 is arranged around the outside of the camera module 100, and the optical lens 200 is arranged around the outside of 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 enclosure 542, the main body 541 and the second light-shielding foam 620, thereby preventing the light in the optical lens 200 from directly entering the camera module 100 and adversely affecting the shooting effect of the camera module 100.
