[0001] This application belongs to the technical field of electronic products, specifically relating to an electronic device. Background Technology

[0002] As people become increasingly reliant on smartphones, the rear camera area of ​​modern smartphones is becoming more and more functional to meet diverse user needs. Among these features, some smartphones include infrared LEDs in the rear camera area. However, adding infrared LEDs increases the overall thickness of the rear camera module, causing discomfort for users and negatively impacting the user experience. Summary of the Invention

[0003] The purpose of this application is to provide an electronic device that can at least solve problems such as the excessive thickness of the rear camera trim affecting user experience.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows: This application provides an electronic device, including: a decorative component assembly, a support assembly, a flexible circuit board, and a light-emitting device. The decorative component assembly covers the support assembly, the flexible circuit board is disposed on the support assembly, and the support assembly includes a protrusion. The flexible circuit board includes a first flexible circuit board, the light-emitting device includes a first light-emitting device, the first light-emitting device is disposed on the side of the protrusion facing the sidewall of the decorative component assembly, the first flexible circuit board is disposed between the first light-emitting device and the support assembly, the decorative component assembly is provided with a reflective element opposite to the first light-emitting device, the reflective element is used to reflect the signal emitted by the first light-emitting device along a first direction, the first direction being parallel to the thickness direction of the decorative component assembly.

[0005] In this embodiment, the first light-emitting device is disposed on the side of the protrusion, so that the first light-emitting device can emit signals toward the sidewall of the decorative component assembly. Simultaneously, a reflector provided on the decorative component assembly can reflect the signal emitted by the first light-emitting device, allowing the signal to propagate along the first direction. Compared to related technologies, in this embodiment, the first light-emitting device is not disposed on the inner side of the decorative component assembly along the thickness direction of the electronic device, but rather on the side of the protrusion facing the sidewall of the decorative component assembly. This avoids occupying space between the support assembly and the decorative component assembly in the thickness direction, which helps reduce the stacking height of the decorative component assembly and thus alleviates the problem of user experience being affected by the large thickness of the decorative component assembly. Furthermore, the reflector can reflect the signal emitted by the first light-emitting device, allowing the signal to propagate along the first direction, thereby meeting the operational requirements of the first light-emitting device.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0010] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0011] refer to Figures 1 to 11 This application discloses an electronic device, which can be a mobile phone, tablet, e-reader, or other similar device. The disclosed electronic device includes a decorative component assembly 40, a bracket assembly 10, a flexible circuit board 30, and a light-emitting device 20.

[0012] The decorative component 40 serves to shield and decorate, improving the appearance of the electronic device. The bracket component 10 supports and fixes the motherboard of the electronic device to ensure its stability. The flexible circuit board 30 transmits signals to provide power to the light-emitting device 20 and sends control signals to it to meet its operational requirements. The light-emitting device 20 can perform corresponding functions, including infrared devices, ranging devices, and other components, which are not specifically limited here.

[0013] Decorative component 40 is disposed over bracket assembly 10 to cover bracket assembly 10 and for decorative purposes. Optionally, decorative component 40 may include a top wall and side walls, wherein the top wall is perpendicular to the thickness direction of the electronic device to cover the top surface of bracket assembly 10, and the side walls extend along the thickness direction of the electronic device to cover the sides of bracket assembly 10. Exemplarily, decorative component 40 may have a shell-like structure that can be snapped onto the outside of bracket assembly 10.

[0014] The flexible circuit board 30 is disposed on the support assembly 10 so that the support assembly 10 can support and fix the flexible circuit board 30, ensure the installation stability of the flexible circuit board 30, and prevent the flexible circuit board 30 from shaking randomly, causing collision damage and noise.

[0015] Among them, such as Figure 9 As shown, the flexible circuit board 30 may include a first flexible circuit board 31. Correspondingly, the light-emitting device 20 includes a first light-emitting device 21. The first light-emitting device 21 is connected to the first flexible circuit board 31 so that the first light-emitting device 21 is powered through the first flexible circuit board 31 so that the first light-emitting device 21 can work normally.

[0016] The bracket assembly 10 includes a protrusion 11 that protrudes along the thickness direction of the electronic device and is disposed on the top of the bracket assembly 10. A first light-emitting device 21 is disposed on the side of the protrusion 11 facing the sidewall of the decorative component assembly 40. A first flexible circuit board 31 is disposed between the first light-emitting device 21 and the bracket assembly 10. In this way, the bracket assembly 10 can support and fix the first flexible circuit board 31 and the first light-emitting device 21 to ensure the installation stability of the first flexible circuit board 31 and the first light-emitting device 21.

[0017] In some embodiments of this application, the electronic device includes a housing assembly and a motherboard. The motherboard is disposed within the housing assembly, which has mounting holes. The decorative component assembly 40 is disposed within the housing assembly and covers the mounting holes. A bracket assembly 10 is partially disposed within the housing assembly and stacked on top of the motherboard, with a protrusion of the bracket assembly 10 passing through the mounting holes. It is understood that the decorative component assembly 40 has a cover-like structure, having side walls and a top wall. Therefore, a portion of the protrusion 11 of the bracket assembly 10 is opposite to the side wall of the decorative component assembly 40, and a portion of the protrusion 11 of the bracket assembly 10 is opposite to the top wall of the decorative component assembly 40.

[0018] In this embodiment, the first light-emitting device 21 is disposed on the side of the protrusion 11 so that the first light-emitting device 21 can emit a signal toward the side wall of the decorative component assembly 40. At the same time, the reflector 100 provided on the decorative component assembly 40 can reflect the signal emitted by the first light-emitting device 21, so that the signal propagates along the first direction.

[0019] Compared to related technologies, in this embodiment, the first light-emitting device 21 is not disposed inside the decorative component assembly 40 along the thickness direction of the electronic device, but is disposed on the side of the protrusion 11 facing the sidewall of the decorative component assembly 40. This avoids occupying the space between the support assembly 10 and the decorative component assembly 40 in the thickness direction, which helps to reduce the stacking height of the decorative component assembly 40 and thus alleviates the problem of user experience being affected by the large thickness of the decorative component assembly 40. Furthermore, the reflector 100 can reflect the signal emitted by the first light-emitting device 21, enabling the signal to be transmitted along the first direction, thereby meeting the working requirements of the first light-emitting device 21.

[0020] Considering that the first light-emitting device 21 is disposed toward the sidewall of the decorative component assembly 40 and emits signals in that direction, in order to transmit the signals along the thickness direction of the electronic device, the decorative component assembly 40 may be provided with a reflector 100, which is disposed opposite to the first light-emitting device 21. The reflector 100 is used to reflect the signals emitted by the first light-emitting device 21 along a first direction, wherein the first direction is parallel to the thickness direction of the decorative component assembly 40 (i.e., the thickness direction of the electronic device).

[0021] Based on the above configuration, the reflector 100 can reflect the light emitted by the first light-emitting device 21, enabling the light to propagate along the first direction and eventually reach the outside of the electronic device.

[0022] Optionally, a portion of the decorative component assembly 40 may be provided with a sloping surface, and a reflector 100 may be disposed on the sloping surface to reflect the light emitted by the first light-emitting device 21.

[0023] For example, the reflector 100 may be a sheet-like structure with reflective function, or the reflector 100 may be a prism, or the reflector 100 may include a sheet-like structure with reflective function and a prism. Other forms of the reflector 100 are not specifically limited here.

[0024] In some more specific embodiments, the surface of the reflector 100 may be plated with mirror gold or fitted with a separate mirror to form a reflective surface.

[0025] refer to Figure 10 In some embodiments, the electronic device may also include a conductor 50 disposed on the decorative component assembly 40 for conducting light emitted by the first light-emitting device 21 to reduce light attenuation during propagation.

[0026] Alternatively, the conductor 50 can be positioned and engaged with the decorative component assembly 40 via a hole-shaft structure and secured with adhesive backing 80.

[0027] Optionally, the conductive member 50 may include an incident surface 51, an exit surface 52, and an inclined surface 53. The incident surface 51 is disposed opposite to the first light-emitting device 21 and is used for incident light; the inclined surface 53 abuts against the reflector 100 and is used for transmitting light, allowing the light to reach the reflector 100 and be reflected by it; the exit surface 52 and the inclined surface 53 are spaced apart along a first direction, and the exit surface 52 is perpendicular to the first direction, for emitting light.

[0028] Optionally, the angle between the inclined surface 53 and the first direction can be in the range of 30° to 75°, such as 30°, 45°, 60°, 75°, etc. Of course, it can also be other degrees, which are not specifically limited here.

[0029] For example, the conductor 50 can be an optical element for transmitting light and is beneficial for reducing the energy attenuation of light within the conductor 50.

[0030] Continue to refer to Figure 9 In some embodiments, the surface of the protrusion 11 facing the sidewall of the decorative component assembly 40 can be a first mounting surface, and the bracket assembly 10 has a second mounting surface in the area where the protrusion 11 is not provided, and the second mounting surface is set at an angle to the first mounting surface. Optionally, the second mounting surface can be perpendicular to the first direction. In this case, the first mounting surface and the second mounting surface are perpendicular to each other. Of course, they can also be at an angle greater than 90° or less than 90°, which can be set according to actual needs.

[0031] A portion of the first flexible circuit board 31 can be disposed on the second mounting surface. Meanwhile, since the area of ​​the first flexible circuit board 31 with the first light-emitting device 21 is disposed on the first mounting surface, the two areas of the first flexible circuit board 31 are bent relative to each other so that an angle is formed between the two areas.

[0032] In some more specific embodiments, the two regions of the first flexible circuit board 31 can be bent by 90° to accommodate the setting angle between the first mounting surface and the second mounting surface.

[0033] In some embodiments, the first mounting surface may be provided with a groove, and a portion of the first flexible circuit board 31 and the first light-emitting device 21 are both disposed in the groove. In this way, the groove can accommodate a portion of the first flexible circuit board 31 and the first light-emitting device 21, which is beneficial to improving the installation stability of the first flexible circuit board 31 and the first light-emitting device 21.

[0034] Furthermore, the electronic device may also include a sealing sleeve 60, such as Figure 9 and Figure 10As shown, the sealing sleeve 60 surrounds the periphery of the first light-emitting device 21 and is sealed between the first light-emitting device 21 and the groove. In this way, the sealing sleeve 60 can play a sealing role between the first light-emitting device 21 and the groove. In addition, the sealing sleeve 60 can also play a buffering role.

[0035] Optionally, the sealing sleeve 60 can be a silicone sleeve, a plastic sleeve, etc.

[0036] It should be noted that, since the first light-emitting device 21 is located in the groove, the sidewall of the groove can shield the sealing sleeve 60, preventing it from being scraped during assembly. Optionally, a baffle can be provided on a partial sidewall of the groove to further block the sealing sleeve 60.

[0037] Continue to refer to Figure 9 In some embodiments, the bracket assembly 10 may be provided with a first positioning structure, and correspondingly, the first flexible circuit board 31 may be provided with a second positioning structure, and the first positioning structure and the second positioning structure are positioned together. In this way, during the installation of the first flexible circuit board 31, the positioning of the first flexible circuit board 31 can be achieved by the positioning cooperation of the first positioning structure and the second positioning structure, so as to ensure the installation position accuracy of the first flexible circuit board 31.

[0038] Optionally, the first positioning structure can be a positioning pin, positioning post, etc., and correspondingly, the second positioning structure can be a positioning hole, positioning groove, etc. In addition, the first and second positioning structures can be other structures, which are not specifically limited here.

[0039] refer to Figures 1 to 8 In some embodiments, the flexible circuit board 30 may include a second flexible circuit board 32, the light-emitting device 20 may include a second light-emitting device 22, the protrusion 11 may be provided with a relief groove 12 on the side facing the top wall of the decorative component assembly 40, the second light-emitting device 22 is disposed in the relief groove 12, and the second flexible circuit board 32 is disposed between the relief groove 12 and the second light-emitting device 22.

[0040] Based on the above settings, the second flexible circuit board 32 and the second light-emitting device 22 can be provided with clearance space by setting clearance groove 12, so as to reduce the height of the second light-emitting device 22 protruding along the thickness direction of the electronic device, thereby helping to reduce the thickness of the electronic device.

[0041] In some embodiments, the bottom wall of the recessed groove 12 may be provided with a through hole, and the electronic device may also include a reinforcing member 70, with a portion of the reinforcing member 70 embedded in the through hole. Based on this, the through hole can be blocked by the reinforcing member 70, and the reinforcing member 70 can support the second flexible circuit board 32 and the second light-emitting device 22, and strengthen the second flexible circuit board 32, thereby improving the installation stability of the second flexible circuit board 32 and the second light-emitting device 22.

[0042] Optionally, the reinforcing member 70 is detachably provided at the recess 12 for easy disassembly and assembly.

[0043] Furthermore, such as Figure 2 To the diagram, Figures 6 to 8 As shown, the reinforcing member 70 may have a recessed portion 71 in the middle, which fits into the through hole. The second flexible circuit board 32 and the second light-emitting device 22 are disposed in the recessed portion 71. Based on this, a portion of the second flexible circuit board 32 and the second light-emitting device 22 can be accommodated by the recessed portion 71, thereby reducing the protrusion height of the second light-emitting device 22 along the thickness direction of the electronic device, which is beneficial to reducing the thickness of the electronic device.

[0044] refer to Figures 4 to 7 In some embodiments, the reinforcing member 70 may have positioning holes 72 at both ends, and the clearance groove 12 may have positioning protrusions 13 at both ends, with the positioning protrusions 13 engaging with the positioning holes 72. Based on this, the positioning engagement between the positioning protrusions 13 and the positioning holes 72 can ensure the installation position accuracy of the reinforcing member 70 on the bracket assembly 10, and further improve the positional accuracy of the second flexible circuit board 32 and the second light-emitting device 22.

[0045] Optionally, the positioning protrusion 13 can be a hot-melt column. In this way, when installing the reinforcing member 70, the hot-melt column can be first inserted into the positioning hole 72, and then the hot-melt column can be heated to deform the hot-melt column and achieve the limiting effect on the reinforcing member 70, effectively preventing the reinforcing member 70 from detaching from the bracket assembly 10.

[0046] refer to Figure 8 In other embodiments, the reinforcing member 70 may have positioning grooves 73 at both ends, and positioning protrusions 13 on both sides of the clearance groove 12, with the positioning protrusions 13 engaging with the positioning grooves 73. Therefore, when installing the reinforcing member 70, the positioning protrusions 13 engage with the positioning grooves 73 to achieve positioning and limiting of the reinforcing member 70.

[0047] In some embodiments, the two ends of the reinforcing member 70 can be bonded and fixed to the bracket assembly 10 respectively by adhesive backing 80. In this way, the reinforcing member 70 can be pre-fixed to the bracket assembly 10, so as to facilitate subsequent fixation by the positioning protrusion 13 cooperating with the positioning hole 72 or the positioning groove 73.

[0048] In some more specific embodiments, after the reinforcing member 70 is bonded to the bracket assembly 10 by the adhesive 80, the hot melt column is hot melted to form a mushroom head, thereby strengthening the fixing effect and preventing the reinforcing member 70 and the second light-emitting device 22 from shaking due to the deactivation of the adhesive 80 after long-term use.

[0049] refer to Figure 4 , Figure 6 and Figure 7 In some embodiments, the two ends of the reinforcing member 70 may each form a first bending portion 74, which protrudes from the second light-emitting device 22 along a first direction.

[0050] Optionally, the two ends of the reinforcing member 70 can be bent toward the side where the second light-emitting device 22 is located along the first direction, so as to form a first bending portion 74 in the two ends of the reinforcing member 70, and the free end of the first bending portion 74 protrudes out of the second light-emitting device 22 along the first direction.

[0051] Based on the above configuration, the first bending portion 74 in both sides can provide support on both sides of the reinforcing member 70. Thus, when the lens of the electronic device is impacted by an external force, the first bending portion 74 in both sides can preferentially support the lens to reduce the amount of lens deformation, alleviate the problem of excessive lens deformation or even breakage, and prevent the lens from deforming and squeezing the second light-emitting device 22, thereby reducing the risk of failure of the second light-emitting device 22.

[0052] refer to Figure 8 In another form of the reinforcing member 70, one end of the reinforcing member 70 can be bent to form a hook portion 75, which hooks and engages with the bracket assembly 10. Optionally, the bracket assembly 10 may be provided with a hook step, and the hook portion 75 extends from the surface of the bracket assembly 10 to the bottom of the bracket assembly 10 and hooks and engages with the hook step to ensure the reliability of the connection between one end of the reinforcing member 70 and the bracket assembly 10.

[0053] It should be noted that by hooking the hook part 75 with the bracket assembly 10, one end of the reinforcing member 70 is limited, which can effectively prevent the adhesive 80 from gradually deactivating after long-term use, causing one end of the reinforcing member 70 to lift up relative to the bracket assembly 10.

[0054] Continue to refer to Figure 8 The other end of the reinforcing member 70 has a second bend 76, and the second bend 76 has a snap-fit ​​hole 77. Correspondingly, the bracket assembly 10 may have a snap-fit ​​protrusion. The snap-fit ​​hole 77 engages with the snap-fit ​​protrusion, thus ensuring the reliability of the connection between the other end of the reinforcing member 70 and the bracket assembly 10.

[0055] It should be noted that the snap-fit ​​hole 77 and the snap-fit ​​protrusion engage without the need for screws, allowing for quick snap-fitting or disassembly, which facilitates the installation and removal of the reinforcing component 70.

[0056] In some embodiments, a slope portion may be provided in a part of the second flexible circuit board 32. The slope portion can adapt to the large-angle slope of the transition position of the support assembly 10, so as to prevent the second flexible circuit board 32 from being suspended relative to the support assembly 10 and affecting the stability of the second flexible circuit board 32.

[0057] refer to Figure 1 , Figure 2 and Figure 8 In some embodiments, the flexible circuit board 30 may further include a third flexible circuit board 33, which is disposed on the support assembly 10, and the first flexible circuit board 31 and the second flexible circuit board 32 are respectively connected to the third flexible circuit board 33; the electronic device may further include a motherboard, which is located on the side of the support assembly 10 opposite to the decorative component assembly 40, and the third flexible circuit board 33 is connected to the motherboard. In some embodiments of this application, the first flexible circuit board 31, the second flexible circuit board 32, and the third flexible circuit board 33 are integrally formed. In other embodiments of this application, the first flexible circuit board 31, the second flexible circuit board 32, and the third flexible circuit board 33 are separate connected structures.

[0058] Based on the above configuration, the signals emitted by the motherboard can be transmitted to the first flexible circuit board 31 and the second flexible circuit board 32 through the third flexible circuit board 33, and signals can be transmitted to the first light-emitting device 21 and the second light-emitting device 22 through the first flexible circuit board 31 and the second flexible circuit board 32, respectively.

[0059] refer to Figure 11 In some embodiments, the electronic device may further include a receiver 91 and a transmitter 92. The receiver 91 is connected to the flexible circuit board 30, and the transmitter 92 is connected to the motherboard of the electronic device. The receiver 91 and the transmitter 92 are wirelessly coupled to transmit power from the motherboard to the flexible circuit board 30 to power the light-emitting device 20. It should be noted that the receiver 91 and the transmitter 92 can form an electromagnetic induction wireless transmission module to transmit signals between the flexible circuit board 30 and the motherboard.

[0060] Considering that the light-emitting device 20 does not need to emit light continuously in some cases, thus reducing its overall power consumption, the electromagnetic induction wireless transmission module can provide signals to the flexible circuit board 30, and the transmitter 92 can receive signals from the motherboard.

[0061] Taking the power supply of the infrared light-emitting device through the motherboard as an example, the transmitter 92 is powered by the motherboard and emits a low-power alternating magnetic field. The receiver 91 is powered by induction to supply power to the infrared light-emitting device, so as to provide power to the infrared light-emitting device for a short time. This allows the infrared light-emitting device to emit a weak signal of intermittent pulses, thereby completing the remote control function.

[0062] Because the light-emitting device 20 uses a passive power supply, the flexible circuit board 30 can be independently arranged on one side of the bracket assembly 10 without being connected to the motherboard by folding, thus effectively preventing the flexible circuit board 30 from being bent.

[0063] In some embodiments, the flexible circuit board 30 may have a first connecting portion and a second connecting portion, wherein the light-emitting device 20 is disposed on the first connecting portion, and the second connecting portion is used to connect to the motherboard. Based on this, the light-emitting device 20 and the motherboard can be electrically connected via the flexible circuit board 30 to transmit signals between the light-emitting device 20 and the motherboard. Optionally, a BTB connector can be used to connect the second connecting portion to the motherboard.

[0064] Furthermore, the first connecting part and the second connecting part are located on the same side of the support assembly 10 along the first direction. This facilitates the distribution of the flexible circuit board 30 on the support assembly 10 and can alleviate the problem of the flexible circuit board 30 being affected by excessively large folding angles on both sides of the support assembly 10.

[0065] Based on the above configuration, the light-emitting device 20 can be connected to the motherboard via the flexible circuit board 30 to transmit signals between the light-emitting device 20 and the motherboard. Furthermore, the first connecting part and the second connecting part are both located on the same side of the support assembly 10, so that the flexible circuit board 30 will not bend to the sides of the support assembly 10. This effectively avoids the situation where the flexible circuit board 30 is bent to the sides and thus effectively alleviates the problem of damage or even breakage of the flexible circuit board 30. This is beneficial to improving the reliability of the flexible circuit board 30 in long-term use and reducing the risk of failure.

[0066] In some more specific embodiments, the flexible circuit board 30 may include a first flexible circuit board 31 and a second flexible circuit board 32, and the light-emitting device 20 may include a first light-emitting device 21 and a second light-emitting device 22. The first light-emitting device 21 may be installed on the side of the protrusion 11 facing the decorative component assembly 40, and the first flexible circuit board 31 is located between the first light-emitting device 21 and the bracket assembly 10. The second light-emitting device 22 may be disposed in the recess 12 of the protrusion 11 facing the top wall of the decorative component assembly 40, and the second flexible circuit is located between the second light-emitting device 22 and the recess 12.

[0067] For example, the second light-emitting device 22 can be mounted to the bracket assembly 10 using different types of reinforcing members 70, while the first light-emitting device 21 can be directly mounted to the bracket assembly 10 without the reinforcing members 70.

[0068] In addition, the light-emitting device 20 and the motherboard can directly use a flexible circuit board 30 to achieve signal transmission, or a transmitter 92 and a receiver 91 can be added to the contact of the flexible circuit board 30 to achieve wireless signal transmission.

[0069] It should be noted that the technical features in the embodiments of this application can be combined with each other to form different technical solutions, and multiple embodiments can also share some technical features, as long as there is no contradiction.

[0070] In summary, the embodiments of this application can install the second light-emitting device 22 by means of the reinforcing member 70 and set the flexible circuit board 30 as a whole on the same side of the bracket assembly 10, thereby effectively solving the problem of the flexible circuit board 30 being bent due to limited installation space in related technologies. Furthermore, this type of flexible circuit board 30 does not need to be folded 180°, making the structure of the flexible circuit board 30 simpler, and its reliability is higher over long-term use, reducing the risk of product failure.

[0071] For the thickness bottleneck position of the second light-emitting device 22 area, the second light-emitting device 22 can be supported by the reinforcing member 70 itself, which can save one layer of the insert of the bracket assembly 10, so that the bracket assembly 10 can be perforated to reduce the thickness of the decorative component assembly 40, thereby improving the appearance performance of the product.

[0072] By utilizing the empty space of the decorative component assembly 40 to set up the conductive component 50, and changing the propagation path of light through the conductive component 50, it is possible to solve the problem of dead bending of the first flexible circuit board 31 caused by limited space in the thickness direction.

[0073] The flexible circuit board 30 is independently positioned on the bracket assembly 10 by passive power supply induction triggering, without the need to connect to the motherboard by folding the flexible circuit board 30, thus effectively avoiding the situation of the flexible circuit board 30 being bent.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
