[0001] Cross Reference to Related Applications

[0002] This application claims priority to the Chinese Patent Application No. 202410443322.7, filed on April 12, 2024, and entitled "Electronic device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application belongs to the technical field of light supplement, and specifically relates to an electronic device. BACKGROUND

[0004] With the development of society, electronic devices have become indispensable products in people's daily life and work. The camera of an electronic device can meet various shooting needs of users. With the increasing demand of users for the image quality of the camera, the related structural design of the camera is also facing great challenges.

[0005] To improve the image quality of the camera, when designing the electronic device, a light supplement lamp can be added to improve the ambient brightness, so as to achieve a better shooting effect. The camera can shoot close-up and long-range scenes. However, the light supplement method of the current light supplement lamp is relatively single, which leads to an unsatisfactory shooting effect of the camera. SUMMARY

[0006] The present application provides an electronic device, which comprises a shell and a light supplement assembly. The shell comprises a battery cover and a decorative ring. The decorative ring is connected to the battery cover. The decorative ring is located on the side of the battery cover away from the inner cavity of the electronic device. The battery cover is provided with a first light transmission hole. The light supplement assembly comprises a first circuit board, a light supplement lamp and a liquid crystal light guide piece. The light supplement lamp is arranged on the first circuit board. At least a part of the first circuit board is located in the first light transmission hole. The liquid crystal light guide piece is arranged on the light emitting side of the light supplement lamp. The liquid crystal light guide piece comprises a liquid crystal layer. When the liquid crystal light guide piece is in a power-off state, the light emitted by the light supplement lamp is reflected by the liquid crystal layer and then emitted. When the liquid crystal light guide piece is in a power-on state, the light emitted by the light supplement lamp directly transmits through the liquid crystal layer and then emits.

[0007] In the embodiment of the present application, the light supplement assembly adds a liquid crystal light guide piece, the liquid crystal light guide piece includes a liquid crystal layer, in the case that the liquid crystal light guide piece is in a power-off state, the light emitted by the light supplement lamp is reflected by the liquid crystal layer and then emitted, at this time the light presents a scattering effect; in the case that the liquid crystal light guide piece is in a power-on state, the light emitted by the light supplement lamp is transmitted through the liquid crystal layer and then emitted directly, that is, the light is relatively concentrated. As can be seen, when the liquid crystal light guide piece is in different states, the propagation path of the light emitted by the light supplement lamp after entering the liquid crystal layer is different, thereby making the light emitted by the light supplement lamp produce different light supplement effects after passing through the liquid crystal light guide piece, so as to better adapt to the camera and improve the shooting effect of the electronic device, solving the problem of the related art that the shooting effect of the electronic device is not ideal due to the single light supplement mode of the light supplement lamp.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly described below with reference to 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 of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0023] 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 generally of a kind and do not limit 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.

[0024] The light supplement assembly and the electronic device disclosed by the embodiments of the present application will be described in detail in combination with the drawings, specific embodiments and application scenarios.

[0025] Please refer to FIG. 1-FIG. 16, the present application discloses a light supplement assembly, which can be applied to an electronic device, the electronic device can include a camera, the light supplement assembly is adjacent to the camera, when the camera is in working state, the light supplement assembly can be in working state at the same time, so as to realize the light supplement operation in the shooting process, of course, the light supplement assembly can also work alone, so as to be used as a flashlight and other functional devices.

[0026] The light supplement assembly can include a first circuit board 110, a light supplement lamp 120 and a liquid crystal light guide piece 130, wherein: the light supplement lamp 120 is arranged on the first circuit board 110, the first circuit board 110 can be electrically connected with the mainboard 500 of the electronic device through a board-to-board connector or other connecting structure, the first circuit board 110 can supply power for the light supplement lamp 120, and can control the state of the light supplement lamp 120, and optionally, the light supplement lamp 120 can be an LED lamp; the liquid crystal light guide piece 130 is arranged on the light emitting side of the light supplement lamp 120, that is, the light emitted by the light supplement lamp 120 needs to pass through the liquid crystal light guide piece 130 before being emitted, and the liquid crystal light guide piece 130 includes a liquid crystal layer 131. Optionally, the number of the liquid crystal light guide piece 130 can be one or more, and multiple liquid crystal light guide pieces 130 can be stacked.

[0027] The liquid crystal layer 131 includes a plurality of liquid crystal molecules, which can be deflected under the action of an electric field, and at the same time, when light enters the liquid crystal light guide piece 130, the liquid crystal molecules can change the propagation direction of the light, and the deflection degree of the liquid crystal molecules is different, and the change degree of the propagation direction of the light is different. Optionally, the liquid crystal light guide piece 130 further includes a base body, and the liquid crystal layer 131 is arranged on the base body, which can realize the packaging of the liquid crystal layer 131, and optionally, the base body can be an organic solid polymer base body, at this time, the liquid crystal layer 131 is a polymer dispersed liquid crystal layer (PDLC, Polymer Dispersed Liquid Crystal), and the liquid crystal molecules of the liquid crystal layer 131 are dispersed in the organic solid polymer base body in the form of micrometer-sized droplets. Optionally, the material of the base body can be polyethylene glycol terephthalate (PET, Poly Ethylene glycol Terephthalate), and of course, it can also be other materials, which are not limited by the embodiments of the present application.

[0028] Optionally, the liquid crystal light guide 130 has a power-off state and a power-on state. When the liquid crystal light guide 130 is in the power-off state, the light emitted by the light supplement lamp 120 is reflected by the liquid crystal layer 131 and then emitted. When the liquid crystal light guide 130 is in the power-on state, the light emitted by the light supplement lamp 120 directly transmits through the liquid crystal layer 131 and is emitted. Specifically, when the liquid crystal light guide 130 is in the power-off state, the optical axis of the liquid crystal molecules of the liquid crystal layer 131 is preferentially oriented, and the optical axis of all the liquid crystal molecules is in a disordered orientation state. Since the liquid crystal is a strong optical and dielectric anisotropic material, the effective refractive index and the matrix refractive index are quite different, the transmission rate is low, the light entering the liquid crystal layer 131 is reflected by the liquid crystal layer 131, and then scattered, and finally dispersed and emitted. In this state, the liquid crystal light guide 130 is in a semi-transparent milky white state, as shown in FIGS. 7 and 17. At this time, the liquid crystal light guide 130 is similar to a diffusion film, and the field of view formed by the light after the liquid crystal layer 131 is relatively large, and the light supplement assembly can cooperate with the camera to meet the light supplement requirement in close-range shooting. As shown in FIGS. 8, 9 and 18, when the liquid crystal light guide 130 is in the power-on state, the liquid crystal molecules of the liquid crystal layer 131 are affected by the electric field. Since the liquid crystal molecules have polarity, they will be distributed in the electric field under the action of force. The optical axis of the liquid crystal molecules extends along the direction of the electric field (as shown in FIG. 8). The refractive index of the liquid crystal molecules and the matrix refractive index are matched to a certain extent, and the light can directly pass through the gap between adjacent liquid crystal molecules and then be transmitted in a straight state. At this time, the liquid crystal light guide 130 is in a transparent state (as shown in FIG. 9). The transmission rate of the liquid crystal light guide 130 is relatively high, similar to transparent glass. The field of view formed by the light after the liquid crystal layer 131 is relatively small, and the distant place is in a high-brightness state. The light supplement assembly can cooperate with the camera to meet the light supplement requirement in long-range shooting. Of course, there can be light reflected by the liquid crystal molecules in this state, but the light is still emitted after being reflected through the gap between adjacent liquid crystal molecules. When the liquid crystal light guide 130 is switched from the power-on state to the power-off state, the liquid crystal molecules return to the disordered arrangement state.

[0029] As described above, when the liquid crystal light guide 130 is in the power-off state, the light emitted by the light supplement lamp 120 is reflected by the liquid crystal layer 131 and then emitted, and the light presents a scattering effect at this time. When the liquid crystal light guide 130 is in the power-on state, the light emitted by the light supplement lamp 120 directly transmits through the liquid crystal layer 131 and is emitted, that is, the light is relatively concentrated. It can be seen that when the liquid crystal light guide 130 is in different states, the propagation path of the light emitted by the light supplement lamp 120 after entering the liquid crystal layer 131 is different, so that the light emitted by the light supplement lamp 120 produces different light supplement effects after the liquid crystal light guide 130, thereby better adapting to the camera to improve the shooting effect of the electronic device.

[0030] Further optionally, the energization parameter of the liquid crystal light guide 130 can be adjusted so that the field of view angle formed by the light emitted by the light supplement lamp 120 after passing through the liquid crystal layer 131 can be adjusted. It should be noted that the energization parameter here can be the voltage applied to the liquid crystal light guide 130. When the voltage is zero, it means that the liquid crystal light guide 130 is not energized, i.e., in a power-off state. When the voltage is a non-zero value, it means that the liquid crystal light guide 130 is in an energized state. The field of view angle here refers to the angle between the two edges of the illumination range of the light emitted by the light supplement lamp 120 after passing through the liquid crystal light guide 130. When the energization parameter of the liquid crystal light guide 130 is different, the state of the liquid crystal molecules in the liquid crystal layer 131 will change, the propagation path of the light emitted by the light supplement lamp 120 after entering the liquid crystal layer 131 will change, and then different field of view angles are formed, the light supplement range of the light supplement lamp 120 is variable, so that the light emitted by the light supplement lamp 120 after passing through the liquid crystal light guide 130 produces different light supplement effects, so as to better adapt to the camera, thereby improving the shooting effect of the electronic device.

[0031] Optionally, when the liquid crystal light guide 130 is in an energized state, the voltage applied to the liquid crystal light guide 130 can be adjusted, so as to adjust the deflection degree of the liquid crystal molecules, so that the light emitted by the light supplement lamp 120 forms more different field of view angles after passing through the liquid crystal layer 131, so as to more accurately match the shooting mode of the camera, so as to obtain a more ideal shooting effect. Moreover, this adjustment process can be automatically performed, for example, the distance between the photographed object and the camera can be automatically detected, so as to adjust the energization parameter of the liquid crystal light guide 130 according to the distance.

[0032] In order to enrich the functions of the light supplement assembly, in an optional embodiment, the light supplement assembly further comprises an infrared remote control device 140, the infrared remote control device 140 is arranged on the first circuit board 110, and the infrared remote control device 140 and the light supplement lamp 120 are located on the same side of the first circuit board 110, that is, the side of the first circuit board 110 on which the light supplement lamp 120 is arranged is also provided with the infrared remote control device 140, and the light supplement lamp 120 and the infrared remote control device 140 are both directed to the outside of the electronic device. The first circuit board 110 can supply power to the infrared remote control device 140 and control the state of the infrared remote control device 140, thereby realizing the infrared remote control function.

[0033] Further, the light supplement assembly can further include at least one of an NTC resistor (Negative Temperature Coefficient) 192 and a heat dissipation film 193, wherein the NTC resistor 192 is arranged on the first circuit board 110, and the NTC resistor 192 and the light supplement lamp 120 are located on the same side of the first circuit board 110, and the distance between the NTC resistor 192 and the light supplement lamp 120 can be controlled within a small range, so that the NTC resistor 192 can detect the temperature of the light supplement lamp 120 when the light supplement lamp 120 works, so as to prevent the light supplement lamp 120 from being damaged or affecting the normal work of other components due to high temperature, and at the same time, the experience of the user using the electronic device can be improved; the heat dissipation film 193 is arranged on the first circuit board 110, and the heat dissipation film 193 is arranged opposite to the light supplement lamp 120, so that the heat dissipation film 193 can dissipate heat for the light supplement lamp 120, so as to prevent the light supplement lamp 120 from being damaged or affecting the normal work of other components due to high temperature, and at the same time, the experience of the user using the electronic device can be improved, and optionally, the heat dissipation film 193 can be a pyrolysis heat dissipation film (PGS heat dissipation film).

[0034] Optionally, the number of the light supplement lamp 120 can be only one, which can be the cold light lamp 121 or the warm light lamp 122. In other embodiments, the light supplement lamp 120 includes the cold light lamp 121 and the warm light lamp 122, and the cold light lamp 121 and the warm light lamp 122 are arranged on the first circuit board 110. After being arranged in this way, the states of the cold light lamp 121 and the warm light lamp 122 can be flexibly controlled, so that the light supplement assembly has both cold light effect and warm light effect, and specifically, the cold light lamp 121 can be in a light-emitting state, and the warm light lamp 122 can be in an extinguishing state, so as to bring the cold light effect; or the cold light lamp 121 can be in an extinguishing state, and the warm light lamp 122 can be in a light-emitting state, so as to bring the warm light effect; of course, the cold light lamp 121 and the warm light lamp 122 can be in a light-emitting state at the same time, and the overall color temperature, color tone and other optical properties of the light supplement lamp 120 can be adjusted by adjusting the current ratio of the two, so as to achieve a more ideal light supplement effect.

[0035] The number of the cold light lamps 121 and the warm light lamps 122 can be one. In another alternative embodiment, the number of the cold light lamps 121 is at least two, including a first cold light lamp 121a and a second cold light lamp 121b, and the number of the warm light lamps 122 is at least two, including a first warm light lamp 122a and a second warm light lamp 122b. The first cold light lamp 121a and the second cold light lamp 121b are arranged along a first direction, and the first warm light lamp 122a and the second warm light lamp 122b are arranged along a second direction. The first direction and the second direction intersect. At this time, the cold light lamps 121 and the warm light lamps 122 are arranged dispersedly, and when different cold light lamps 121 or different warm light lamps 122 emit light independently, the positions of the light emitted by the light supplement lamps 120 are different, thereby forming different light supplement effects. At the same time, when the cold light lamps 121 and the warm light lamps 122 emit light simultaneously, the cold light and the warm light are distributed dispersedly, thereby bringing more uniform light supplement effects.

[0036] The first direction and the second direction can intersect but not be perpendicular, or the first direction and the second direction can be perpendicular. At this time, the first cold light lamp 121a, the second cold light lamp 121b, the first warm light lamp 122a, and the second warm light lamp 122b are arranged in a diamond shape. In this way, a larger light supplement area and better cold and warm color matching effects can be obtained by using a smaller number of light supplement lamps 120.

[0037] Optionally, the first circuit board 110 can be a hard circuit board or a flexible circuit board. In order to improve the structural strength of the first circuit board 110, a reinforcing structure can be arranged on the first circuit board 110. The reinforcing structure can be arranged at any position of the first circuit board 110. Of course, the reinforcing structure can also not be arranged on the first circuit board 110. Further optionally, the edge of the first circuit board 110 is provided with a first reinforcing plate 112. Optionally, the first reinforcing plate 112 can be arranged on the same side of the light supplement lamp 120 or on different sides. Since the edge of the first circuit board 110 is usually not provided with components and devices, the edge of the first circuit board 110 is more likely to deform. Therefore, arranging the first reinforcing plate 112 on the edge of the first circuit board 110 can obtain more significant reinforcing effects.

[0038] Optionally, the first reinforcing plate 112 can be made of polyethylene glycol terephthalate (PET), and can also be made of other materials, which are not limited in the embodiments of the present application. Further, the first circuit board 110 can be provided with at least one of a second reinforcing plate 113 and a third reinforcing plate 114, wherein the second reinforcing plate 113 is opposite to a board-to-board connector provided at the end of the first circuit board 110 and used to connect the mainboard 500; and the third reinforcing plate 114 can be opposite to a structure provided on the first circuit board 110 and used to connect other devices, such as the first electrical connection part 111 described below.

[0039] Based on the above light supplement assembly, the embodiments of the present application further provide an electronic device, which comprises a shell 200 and the light supplement assembly according to any one of the above embodiments, the light supplement assembly is arranged in the shell 200, and the light supplement lamp 120 of the light supplement assembly can emit light to the outside of the shell 200, thereby realizing the light supplement function.

[0040] In optional embodiments, the shell 200 comprises a battery cover 210 and a decorative ring 220, the decorative ring 220 is connected with the battery cover 210, and the decorative ring 220 is located on the side of the battery cover 210 away from the inner cavity of the electronic device. Optionally, the decorative ring 220 can be connected with the battery cover 210 through a decorative ring support 191. The battery cover 210 is provided with a first light transmission hole 211, and the light supplement lamp 120 is directed to the first light transmission hole 211. Optionally, the light supplement lamp 120 can be located on the side of the first light transmission hole 211 away from the inner cavity of the shell 200, and the light supplement lamp 120 is opposite to the first light transmission hole 211. Alternatively, the light supplement lamp 120 can be at least partially located in the first light transmission hole 211, and the light supplement lamp 120 can also be located on the side of the first light transmission hole 211 close to the inner cavity of the shell 200, and the light supplement lamp 120 is opposite to the first light transmission hole 211. As long as the light emitted by the light supplement lamp 120 can be emitted out through the first light transmission hole 211.

[0041] The first circuit board 110 can be located outside the first light transmission hole 211, or at least a part of the first circuit board 110 can be located in the first light transmission hole 211. In this case, the first circuit board 110 can be installed by using the internal space of the first light transmission hole 211, so that the first circuit board 110 occupies less additional space, which is conducive to the thin and light design of the electronic device.

[0042] When at least a part of the first circuit board 110 is located in the first light transmission hole 211, a first reinforcing plate 112 can be further provided at the edge of the first circuit board 110. In this case, the first reinforcing plate 112 is located in the first light transmission hole 211. Even if the first circuit board 110 is subjected to the force from the battery cover 210, the first circuit board 110 is not easy to deform or even be cut due to the reinforcing effect of the first reinforcing plate 112.

[0043] Further, the light supplement assembly further comprises a decorative sheet 150, the decorative ring 220 is provided with a second light transmission hole 201, and the decorative sheet 150 is at least partially arranged in the second light transmission hole 201, and the light exit surface of the liquid crystal light guide 130 faces the decorative sheet 150. The light emitted by the light supplement lamp 120 can further pass through the decorative sheet 150 after passing through the liquid crystal light guide 130, and finally be emitted to the external environment. The decorative sheet 150 covers the liquid crystal light guide 130 and the light supplement lamp 120, so that the decorative sheet 150 can protect the liquid crystal light guide 130 and the light supplement lamp 120, and prevent dust, liquid and other substances in the external environment from entering the shell 200 to affect the light supplement effect of the light supplement assembly. Further, the decorative sheet 150 can have a certain light guiding effect, for example, the decorative sheet 150 can have a soft light effect, so that the light supplement effect of the light supplement assembly is better. In addition, through the individualized design of the decorative sheet 150, the diversified appearance design of the decorative sheet 150 can be realized, and the individualized design of the decorative sheet 150 is relatively easy to realize, so that the appearance adjustment of the electronic device is easier to realize, and the adjustment space is larger. For example, the decorative sheet 150 can be made of glass, or can be made of other materials.

[0044] Of course, the light supplement assembly can also not include the decorative sheet 150, and the liquid crystal light guide 130 can directly serve as an appearance component.

[0045] As described above, the light supplement assembly can further comprise an infrared remote control device 140, which is arranged on the first circuit board 110, and specifically can be located inside the battery cover 210. In another embodiment, the infrared remote control device 140 is located between the battery cover 210 and the decorative sheet 150. That is, the infrared remote control device 140 can be located outside the battery cover 210, at this time, the infrared remote control device 140 no longer occupies the internal space of the battery cover 210, thereby facilitating the layout of other components in the interior of the battery cover 210; and the shell 200 does not need to be opened for the infrared remote control device 140, so that the number of openings of the electronic device is reduced; at the same time, the infrared remote control device 140 can make full use of the space between the battery cover 210 and the decorative sheet 150 for installation, and the decorative sheet 150 covers the infrared remote control device 140, thereby protecting the infrared remote control device 140 and avoiding the exposure of the infrared remote control device 140 to affect the service life of the infrared remote control device 140 and the appearance texture of the electronic device.

[0046] In the above embodiment, the decorative sheet 150 and the battery cover 210 have a superimposed relationship, and the decorative ring 220, as the mounting base of the decorative sheet 150, also has a superimposed relationship with the battery cover 210, that is, a part of the decorative ring 220 is superimposed with the battery cover 210 in the thickness direction of the battery cover 210, and the overall size of the decorative ring 220 is larger, which can meet the demand of users for large decorative ring 220.

[0047] The decorative sheet 150 has a surface facing the liquid crystal light guide 130 and the infrared remote control device 140, which can be a plane. In other optional embodiments, the decorative sheet 150 is provided with a ring-shaped light-out groove 151 on the side facing the liquid crystal light guide 130, and the orthographic projection of the light supplement lamp 120 is located inside the orthographic projection of the ring-shaped light-out groove 151 in the direction perpendicular to the decorative sheet 150. At this time, the light emitted by the light supplement lamp 120 can be uniformly transmitted to the ring-shaped light-out groove 151, so as to form a light supplement ring at the ring-shaped light-out groove 151, and the light emitted at the light supplement ring can be uniformly emitted to the four directions of the light supplement lamp 120, thereby bringing a more uniform light supplement effect. Alternatively, the ring-shaped light-out groove 151 can be formed by silk printing or the like, and the number of the ring-shaped light-out groove 151 can be one or more.

[0048] In another embodiment, the decorative sheet 150 is provided with a light-shielding area 152, the light-shielding area 152 is opposite to the infrared remote control device 140, and the light-shielding area 152 is provided for the infrared light to pass through. Alternatively, the light-shielding area 152 can be formed by silk printing or the like. The light-shielding area 152 can shield the infrared remote control device 140, so that the user cannot see the infrared remote control device 140 from the outside of the electronic device, thereby improving the appearance quality of the electronic device; at the same time, the light-shielding area 152 will not affect the passing property of the infrared light, thereby ensuring the remote control effect of the infrared remote control device 140. Alternatively, the light-shielding area 152 here can be a circular area or a ring-shaped area, and the embodiments of the present application do not limit this.

[0049] Alternatively, the decorative ring 220 includes a first decorative part 221 and a second decorative part 222 connected in sequence, and the battery cover 210 has a first edge 212 and a second edge 213 opposite to each other, and the first edge 212, the first decorative part 221, the second decorative part 222 and the second edge 213 are arranged in sequence. Alternatively, the decorative ring 220 can be a strip-shaped structure, at this time, the decorative ring 220 can extend along the length direction of the electronic device, and the first edge 212, the first decorative part 221, the second decorative part 222 and the second edge 213 can be arranged in sequence along the length direction of the decorative ring 220, thereby obtaining a more regular and more coordinated layout effect. The first decorative part 221 is provided with a third light-transmitting hole 221a, and the electronic device further includes a camera lens 300, which can be opposite to the camera, thereby protecting the camera, and the camera lens 300 is at least partially arranged in the third light-transmitting hole 221a, and the second decorative part 222 is provided with the second light-transmitting hole 201 described above.

[0050] The top surfaces of the first decorative part 221 and the second decorative part 222 can be flush, or the first decorative part 221 can protrude away from the inner cavity of the shell 200 relative to the second decorative part 222 on the side of the decorative ring 220. After such arrangement, when the electronic device is placed on a placing base such as a table, the battery cover 210 will be inclined relative to the surface of the placing base due to the more protruding first decorative part 221, so that the camera lens 300 and the decorative sheet 150 are less likely to come into contact with the placing base, and the placing base is less likely to scratch the camera lens 300 and the decorative sheet 150. Of course, such arrangement can also prevent the camera lens 300 and the decorative sheet 150 from being collided by other objects when the electronic device falls or the like, thereby protecting the camera lens 300 and the decorative sheet 150.

[0051] Alternatively, the first decorative part 221 and the second decorative part 222 can be integrally formed, i.e., the entire decorative ring 220 is an integral structure, or the decorative ring 220 can also adopt a split structure. Further alternatively, the first decorative part 221 includes a split decorative body 221b and a decorative ring 221c, and the decorative body 221b and the second decorative part 222 can be integrally formed. This embodiment can conveniently achieve the purpose of the first decorative part 221 protruding relative to the second decorative part 222 by the additional decorative ring 221c.

[0052] In further embodiments, the side edge of the first decorative part 221 close to the second decorative part 222 and the second edge 213 are on a first plane 202, and the decorative sheet 150 is located in the space surrounded by the first plane 202 and the battery cover 210. When the electronic device is placed on a placing base such as a table, the first plane 202 here is substantially coincident with the surface of the placing base. This embodiment makes the decorative sheet 150 farther away from the first plane 202, and when the electronic device is placed or collided with other objects, the side edge of the first decorative part 221 close to the second decorative part 222 and the second edge 213 serve as two fulcrums to support the electronic device, and the decorative sheet 150 is less likely to come into contact with the placing base or other objects. As can be seen, this scheme can more reliably place the decorative sheet 150 in contact with other objects, so that the decorative sheet 150 is less likely to be scratched, thereby improving the light supplement effect of the light supplement lamp 120 and the remote control effect of the infrared remote control device 140.

[0053] Of course, in other embodiments, the decorative sheet 150 can also be located outside the space surrounded by the first plane 202 and the battery cover 210.

[0054] The electronic device further includes a battery 400 disposed in the housing 200, in the thickness direction of the electronic device, the first decorative portion 221 is located outside the projection of the battery 400, and the second decorative portion 222 is located inside the projection of the battery 400. That is, in the thickness direction of the electronic device, the position of the first decorative portion 221 is staggered with the position of the battery 400, and the position of the second decorative portion 222 corresponds to the position of the battery 400. Since the first decorative portion 221 protrudes relative to the second decorative portion 222, the first decorative portion 221 is more likely to bear external forces, and the second decorative portion 222 is less likely to bear external forces. Therefore, external forces are not easily transmitted to the second decorative portion 222, and are not easily transmitted to the battery 400, thereby not easily causing the battery 400 to be damaged due to excessive force. Therefore, the embodiment can protect the battery 400 and improve the safety of the battery 400.

[0055] Of course, in other optional embodiments, in the thickness direction of the electronic device, the projection of the first decorative portion 221 and the projection of the battery 400 can also at least partially coincide.

[0056] Further, the light supplement assembly further includes a lampshade 160, the lampshade 160 covers the light supplement lamp 120, the light inlet surface of the lampshade 160 faces the light supplement lamp 120, and the liquid crystal light guide piece 130 is disposed on the light outlet surface of the lampshade 160. Optionally, the lampshade 160 can be made of plastic or other materials. The lampshade 160 here can protect the light supplement lamp 120, thereby preventing the light supplement lamp 120 from colliding with other components; and the lampshade 160 can have a light guiding effect, the light emitted by the light supplement lamp 120 passes through the lampshade 160 and then enters the liquid crystal light guide piece 130, the lampshade 160 can change the propagation direction of the light emitted by the light supplement lamp 120 to improve the light supplement effect; further, the liquid crystal light guide piece 130 is disposed on the light outlet surface of the lampshade 160, so that there is no need to additionally set a component for mounting the liquid crystal light guide piece 130, and therefore the embodiment can simplify the structure of the electronic device, and the thickness of the entire electronic device is smaller, which is conducive to the lightweight design of the electronic device.

[0057] Of course, the light supplement assembly can also not include the lampshade 160, at this time, no other components are disposed between the light supplement lamp 120 and the liquid crystal light guide piece 130, and the liquid crystal light guide piece 130 can be directly fixed on the housing 200, and can be fixed on the decorative ring 220 or the battery cover 210.

[0058] Optionally, the side of the lampshade 160 facing away from the liquid crystal light guide 130 can be provided with a light inlet groove 163, the inner wall of the light inlet groove 163 being the light inlet surface of the lampshade 160, and the light supplement lamp 120 being located in the light inlet groove 163. In this way, the lampshade 160 can surround the light supplement lamp 120, and the light emitted by the light supplement lamp 120 can enter the lampshade 160 more, thereby improving the light utilization rate. Of course, the side of the lampshade 160 facing away from the liquid crystal light guide 130 can also be provided as a flat surface, and in this case, the light supplement lamp 120 is located outside the lampshade 160, and a light shielding structure can be additionally provided to prevent light leakage of the light supplement lamp 120.

[0059] The shape of the light inlet groove 163 described above can be flexibly selected, for example, the cross-sectional shape of the light inlet groove 163 along its depth direction can be arc-shaped, V-shaped, rectangular, etc. In order to facilitate the arrangement of the light supplement lamp 120, the cross-sectional shape of the light inlet groove 163 along its depth direction can be rectangular, which can increase the internal space of the light inlet groove 163, thereby facilitating the arrangement of the light supplement lamp 120.

[0060] Optionally, the lampshade 160 as a whole can adopt a cylindrical structure, and in other optional embodiments, the lampshade 160 includes a flat plate portion 161 and a tapered portion 162 connected together, the flat plate portion 161 protruding relative to the annular peripheral surface of the tapered portion 162, the liquid crystal light guide 130 being arranged on the flat plate portion 161, and the light inlet surface of the tapered portion 162 facing the light supplement lamp 120. The annular peripheral surface of the tapered portion 162 is provided with a reflective layer 162a, which can reflect the light entering the lampshade 160, so that the light propagates towards the position of the liquid crystal light guide 130, so that more light enters the liquid crystal light guide 130. In this embodiment, the protruding flat plate portion 161 can provide a larger surface, thereby facilitating the arrangement of the liquid crystal light guide 130; and the size of the tapered portion 162 is smaller than that of the flat plate portion 161, so that it occupies less space and is more convenient for the layout of other components; and the structure of the flat plate portion 161 and the tapered portion 162 is relatively regular, and the processing of the entire lampshade 160 is simpler and the cost is lower.

[0061] It should be noted that the reflective layer 162a described above can be formed by coating, and the reflective layer 162a can contain Ag component. In addition, when the lampshade 160 is provided with the light inlet groove 163, the light inlet groove 163 can be arranged at one end of the tapered portion 162 close to the light supplement lamp 120.

[0062] Further, the cross-sectional area of the tapered portion 162 gradually increases or gradually decreases in the direction in which the light supplement lamp 120 extends to the liquid crystal light guide 130. In the foregoing embodiment, the cross-sectional area of the entire lamp cover 160 has a tendency to increase in the direction in which the light supplement lamp 120 extends to the liquid crystal light guide 130, and therefore the connecting area between the flat portion 161 and the tapered portion 162 is larger, the connecting portion of the two is not easily damaged, and the structural strength of the entire lamp cover 160 is greater. When the lamp cover 160 is subjected to external forces, the lamp cover 160 is not easily damaged, and therefore the light supplement lamp 120 can be more reliably protected. Furthermore, the size of the lamp cover 160 is smaller closer to the interior of the housing 200, and therefore more space can be reserved for layout of other components, and therefore this embodiment is more convenient for structural design of the electronic device.

[0063] Further, the light supplement assembly further comprises a fixing support 170 connected to the housing 200, and the lamp cover 160 is covered on the light supplement lamp 120 through the fixing support 170. The fixing support 170 is provided with a relief hole 171, and the lamp cover 160 is at least partially arranged in the relief hole 171. In this embodiment, the lamp cover 160 can be mounted on the fixing support 170, and the fixing support 170 is connected to the housing 200, thereby achieving mounting of the lamp cover 160. Optionally, the fixing support 170 can be connected to the decorative ring 220, and the two can be positioned through positioning columns or other structures. The lamp cover 160 is at least partially arranged in the relief hole 171, which on the one hand makes the space additionally occupied by the lamp cover 160 smaller, and the overall thickness of the electronic device is smaller; on the other hand, the lamp cover 160 is closer to the light supplement lamp 120, and therefore light emitted by the light supplement lamp 120 is not easily propagated through devices other than the lamp cover 160, and therefore as many light rays as possible can enter the lamp cover 160, thereby improving the light supplement effect. Furthermore, through the fixing support 170, the lamp cover 160 can be closer to the first circuit board 110, and also will not be too close to the first circuit board 110, and therefore the problem of collision between the lamp cover 160 and the first circuit board 110 is not easily caused, thereby protecting the first circuit board 110.

[0064] The manufacturing material of the fixing support 170 can be selected flexibly. For example, the fixing support 170 can be made of a light-transmitting material. In order to prevent light leakage, the fixing support 170 can be provided as a light-shielding structure, i.e., the fixing support 170 is made of a light-shielding material, so that light is not easily emitted out of the fixing support 170. In addition, the fixing support 170 can have a certain light reflecting capability. Once the light emitted by the light supplement lamp 120 is incident on the fixing support 170, the light can be reflected by the fixing support 170, so that the light emitted by the light supplement lamp 120 is as much as possible to be incident into the lampshade 160, thereby improving the light utilization rate. In addition, a portion of the fixing support 170 is opposite to the first light-transmitting hole 211, and another portion of the fixing support 170 can be located between the decorative sheet 150 and the battery cover 210. At this time, the fixing support 170 can assist in supporting the decorative sheet 150, so as to prevent the decorative sheet 150 from being deformed under stress. When the light supplement assembly further includes the infrared remote control device 140, the fixing support 170 can be provided with a through hole 173, and the infrared remote control device 140 can be located in the through hole 173. In this way, the infrared remote control device 140 is arranged between the decorative sheet 150 and the battery cover 210.

[0065] In an optional embodiment, the fixing support 170 surrounds the lampshade 160, and the fixing support 170 is sealingly connected with the lampshade 160 and the first circuit board 110, so as to form a sealed space between the lampshade 160, the fixing support 170 and the first circuit board 110. First, the sealed space is separated from the external environment of the electronic device, so that dust, liquid and other substances in the external environment are not easily entered into the sealed space, and thus the light supplement lamp 120 is not easily affected. Second, in addition to the lampshade 160, the fixing support 170, the first circuit board 110 and the components for realizing the sealing connection between the fixing support 170, the lampshade 160 and the first circuit board 110 have light-shielding properties. Therefore, the light emitted by the light supplement lamp 120 is not easily leaked out of the sealed space, but is as much as possible to be incident into the lampshade 160, thereby improving the light utilization rate of the light supplement assembly, and reducing the light-shielding components for preventing the light emitted by the light supplement lamp 120 from entering the first light-transmitting hole 211, thereby reducing the cost of the electronic device. Third, when the annular peripheral surface of the tapered portion 162 is provided with the reflective layer 162a, even if the reflective layer 162a is detached, the detached part is sealed in the sealed space, and is not easily in contact with other components in the electronic device, so that short circuit and other conditions that affect the normal operation of the components and the safety of the electronic device are not easily occurred. At this time, the working reliability of the components is higher.

[0066] Of course, the fixing support 170 can not be sealingly connected with the lampshade 160 and the first circuit board 110. For example, the fixing support 170 can be gap-connected with the lampshade 160 and the first circuit board 110.

[0067] As described above, the electronic device further includes the battery 400 disposed in the housing 200, and in the thickness direction of the electronic device, the orthographic projection of the first light-transmitting hole 211 is located outside the orthographic projection of the battery core 410. It should be noted that the battery 400 here includes the battery core 410 and the protection plate 420, and in the thickness direction of the electronic device, the orthographic projection of the first light-transmitting hole 211 can coincide with or not coincide with the orthographic projection of the protection plate 420. On the one hand, the first light-transmitting hole 211 avoids the battery 400, so that the battery 400 can be substantially entirely covered by the battery cover 210, thereby reliably protecting the battery 400; on the other hand, when the decorative ring 220 is subjected to an external force, when the external force is transmitted to the first light-transmitting hole 211, even if deformation occurs at the first light-transmitting hole 211, since the first light-transmitting hole 211 is farther away from the battery 400, the part of the battery cover 210 where the first light-transmitting hole 211 is opened is not easy to press the battery 400 even if it is deformed, and therefore such a design is more conducive to protecting the battery 400. Further, when the first light-transmitting hole 211 accommodates the reflective layer 162a of the lampshade 160, even if the reflective layer 162a falls off, it is not easy to fall near the battery 400, and it is not easy to affect the normal use of the battery 400.

[0068] According to the foregoing, the liquid crystal light guide 130 needs to be powered on, and in order to achieve this purpose, the light supplement assembly further includes a second circuit board 180 connected with the liquid crystal light guide 130. Optionally, the liquid crystal light guide 130 can be connected with the liquid crystal light guide 130 through binding or the like. The second circuit board 180 can be directly electrically connected with the mainboard 500 of the electronic device. However, considering that the distance between the liquid crystal light guide 130 and the mainboard 500 is far, and the liquid crystal light guide 130 is closer to the first circuit board 110, in order to conveniently realize the power-on of the liquid crystal light guide 130, the second circuit board 180 can be electrically connected with the first circuit board 110, that is, the liquid crystal light guide 130 is electrically connected with the first circuit board 110 through the second circuit board 180.

[0069] Further, at least one of the first circuit board 110 and the second circuit board 180 is a flexible circuit board, and one of the first circuit board 110 and the second circuit board 180 comprises a bending portion 101 bent from one side of the fixing support 170 to the other side of the fixing support 170, and the fixing support 170 is bonded with the bending portion 101. Through the bending operation of at least one of the first circuit board 110 and the second circuit board 180, the space occupied by the two can be reduced, and other components can be easily avoided, so that the structure of the electronic device is more compact, and the layout is less difficult. Moreover, through the bonding between the fixing support 170 and the bending portion 101, the position of the first circuit board 110 and the second circuit board 180 relative to the fixing support 170 is not easy to change, even if the electronic device is subjected to external force, the connection between the first circuit board 110 and the second circuit board 180 is not easy to fail, so the electrical connection between the liquid crystal light guide 130 and the first circuit board 110 is more reliable, and such arrangement not only can prevent the first circuit board 110 and the second circuit board 180 from being worn, but also can prevent the bending portion 101 from being warped to interfere with the decorative sheet 150 or the battery cover 210.

[0070] In an optional embodiment, the fixing support 170 is provided with an extension portion 172 extending from the edge of the fixing support 170 to the center of the fixing support 170, and the extension portion 172 is sealingly matched with the first circuit board 110. In this embodiment, the extension portion 172 is provided on the fixing support 170, so that the sealing matching area of the fixing support 170 and the first circuit board 110 is larger, and the sealing effect is improved. It should be noted that the extension portion 172 here can be a ring structure, or a structure provided on a part of the fixing support 170. The latter embodiment can set the extension portion 172 at a position where the size of the fixing support 170 is smaller according to the specific structure of the fixing support 170, so as to increase the matching area of the fixing support 170 and the first circuit board 110, without increasing the overall size of the fixing support 170 too much, so as to avoid the waste caused by the size of the fixing support 170 being too large.

[0071] When the fixing support 170 is provided with the relief hole 171 as described above, the hole wall of the relief hole 171 can be a cylindrical surface, and in this case, the lampshade 160 and the hole wall of the relief hole 171 are left with an assembly gap therebetween along the circumferential direction of the relief hole 171, and the distance therebetween remains unchanged. In this structure, once there is a large difference in the size of the portion provided with the relief hole 171 along the circumferential direction of the relief hole 171, the problem of poor sealing fit between the local part of the fixing support 170 and the first circuit board 110 is likely to occur. Based on this, an extension 172 can be provided at the local part of the fixing support 170, and a part of the extension 172 can serve as the hole wall of the relief hole 171, and in this case, the distance between the lampshade 160 and the hole wall of the relief hole 171 along the circumferential direction of the relief hole 171 will change, and specifically, the distance between the lampshade 160 and the hole wall of the relief hole 171 at the extension 172 is smaller than the distance between the lampshade 160 and the remaining part of the hole wall of the relief hole 171. Such a setting can increase the sealing area of the local part of the fixing support 170 and the first circuit board 110, thereby improving the sealing effect.

[0072] As described above, the light supplement assembly can further include a second circuit board 180, and the liquid crystal light guide 130 is electrically connected to the first circuit board 110 through the second circuit board 180. The first circuit board 110 and the second circuit board 180 can be separately provided, so that the second circuit board 180 and the liquid crystal light guide 130 are first connected into a whole, and then connected to the first circuit board 110, which is more convenient to operate. In addition, the first circuit board 110 and the second circuit board 180 can be separately formed, which has lower process and assembly difficulty, and the maintenance and after-sales cost is reduced, and the stacking between parts is not easily restricted. In order to realize the connection between the first circuit board 110 and the second circuit board 180, the first circuit board 110 is provided with a first electrical connection part 111, and the second circuit board 180 is provided with a second electrical connection part 181, and the first electrical connection part 111 and the second electrical connection part 181 are detachably electrically connected. Such a detachable connection facilitates the maintenance and replacement of the first electrical connection part 111 and the second electrical connection part 181, and the maintenance cost of the electronic device is lower.

[0073] The first electrical connection part 111 and the second electrical connection part 181 described above can be a board-to-board connector, or one of them can be a zero insertion force socket (i.e., a ZIF socket), and the other can be a zero insertion force plug (i.e., a ZIF plug), of course, other structural forms can also be adopted, and the present application embodiment does not limit this.

[0074] In optional embodiments, the decorative sheet 150 and the decorative ring 220, the liquid crystal light guide 130 and the lampshade 160, the lampshade 160 and the fixing support 170, the fixing support 170 and the second circuit board 180, and the bending part 101 and the fixing support 170 can be connected by the double-sided adhesive tape 600, so as to reduce the connection cost on the basis of ensuring the connection strength. It should be noted that the thickness, width, length and other dimensions of the double-sided adhesive tape 600 at each place can be different.

[0075] Optionally, the electronic device disclosed in the present application can be a mobile phone, a tablet computer, an electronic book reader, a game console, a smart watch, or the like. The embodiments of the present application do not limit the specific types of electronic devices.

[0076] The embodiments of the present application are described above in combination with the drawings, but the present application is not limited to the specific embodiments described above, which are only illustrative but not restrictive. Those skilled in the art can make many forms without departing from the scope of the present application under the inspiration of the present application, which are all within the protection of the present application.
