Description

Technical Field

[0001] This application belongs to the field of communication technology, and specifically relates to an electronic device. Background Technology

[0002] With the development of communication technology, electronic devices have become everyday items, and the camera function, as a common function of electronic devices, is specifically realized through the camera to perform video and photo functions.

[0003] In related technologies, electronic devices include a device body and a camera module. The device body includes a connected circuit board and a circuit board bracket. The camera module includes a camera and a camera decorative ring surrounding the camera. The camera decorative ring is connected to the circuit board bracket by adhesive dispensing. The circuit board bracket is embedded with a conductive sheet. One end of the conductive sheet extends to the location of the circuit board, and the other end of the conductive sheet extends to the surface of the circuit board bracket and is soldered with a grounding spring. The grounding spring is then connected to the grounding point of the camera decorative ring, thereby realizing the electrical connection between the camera decorative ring and the circuit board through the grounding spring and the conductive sheet, and realizing the grounding of the camera decorative ring.

[0004] As a result, the camera decorative ring needs to be grounded, and the circuit board bracket also needs to be grounded with a grounding spring and a conductive plate. The grounding structure is relatively complex. Moreover, under the elastic force of the grounding spring, the camera decorative ring will float. This means that the camera decorative ring and the circuit board bracket need to be sealed with adhesive to suppress the floating. During maintenance and disassembly, the camera decorative ring and the circuit board bracket are easily pulled and damaged, making maintenance and disassembly operations complicated. Summary of the Invention

[0005] The purpose of this application is to provide an electronic device that can solve the problem of complex maintenance and disassembly operations for metal decorative rings in related technologies.

[0006] This application provides an electronic device, including a circuit board, a circuit board bracket, fasteners, and a camera decorative ring. The circuit board bracket is disposed on the circuit board, and the camera decorative ring is located on the side of the circuit board bracket facing away from the circuit board. The camera decorative ring has a first connecting hole, the circuit board bracket has a second connecting hole, and the circuit board has a third connecting hole. The fastener passes through the first connecting hole and the second connecting hole and extends into the third connecting hole to simultaneously connect the camera decorative ring, the circuit board bracket, and the circuit board. The fastener is a conductive structure, and the camera decorative ring is electrically connected to the circuit board through the fastener.

[0007] In this embodiment, the camera decorative ring, circuit board bracket, and circuit board are connected by fasteners to achieve relative fixation. The camera decorative ring is electrically connected to the circuit board through conductive fasteners, thereby grounding the camera decorative ring. In this way, the camera decorative ring can be installed and grounded using only fasteners. That is, grounding is achieved directly using the components that install the camera decorative ring, eliminating the need for a separate grounding point on the camera decorative ring and for grounding springs and conductive plates on the circuit board bracket, which simplifies the grounding structure. Moreover, since the camera decorative ring and circuit board bracket are locked together by fasteners, the camera decorative ring is less likely to float, eliminating the need for adhesive to suppress floating. The fasteners can be tightened as needed to install and remove the camera decorative ring, preventing damage to the camera decorative ring and circuit board bracket, which simplifies maintenance and disassembly operations.

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.

[0012] The electronic device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0013] Please refer to Figures 1-2 The electronic device disclosed in this application includes a circuit board 200, a circuit board bracket 100, a fastener 400, and a camera decorative ring 300. The circuit board 200 supplies power to the electronic device's electrical components, the circuit board bracket 100 supports the circuit board 200, the fastener 400 connects the camera decorative ring 300 and the circuit board bracket 100, and the camera decorative ring 300 decorates the camera 820. Specifically, the electronic device also includes a camera 820, and the camera decorative ring 300 surrounds the camera 820.

[0014] The circuit board bracket 100 is disposed on the circuit board 200, and the camera decorative ring 300 is located on the side of the circuit board bracket 100 facing away from the circuit board 200, that is, the circuit board 200 and the camera decorative ring 300 are respectively located on both sides of the circuit board bracket 100. Optionally, the circuit board 200 and the circuit board bracket 100 can be fixedly connected by means of welding, bonding, screw connection, etc.

[0015] Fastener 400 can be threaded fasteners such as screws and bolts. (Reference) Figure 2As shown, the camera decorative ring 300 has a first connecting hole 300a, the circuit board bracket 100 has a second connecting hole 100a, and the circuit board 200 has a third connecting hole 200a. The fastener 400 is relatively long and passes through the first connecting hole 300a, the second connecting hole 100a, and extends into the third connecting hole 200a in sequence, so as to connect the camera decorative ring 300, the circuit board bracket 100, and the circuit board 200 simultaneously. Optionally, the first connecting hole 300a, the second connecting hole 100a, and the third connecting hole 200a can all be through holes. The camera decorative ring 300, the circuit board bracket 100, and the circuit board 200 are connected by riveting through the first connecting hole 300a, the second connecting hole 100a, and the third connecting hole 200a; or, the wall of the third connecting hole 200a is provided with an internal thread, and the fastener 400 passes through the first connecting hole 300a and the second connecting hole 100a in sequence and is threadedly engaged with the third connecting hole 200a, so as to connect the camera decorative ring 300, the circuit board bracket 100, and the circuit board 200, and fix the camera decorative ring 300, the circuit board bracket 100, and the circuit board 200 relatively.

[0016] In this way, the fastener 400 connects the camera decorative ring 300, the circuit board bracket 100 and the circuit board 200 at the same time. The circuit board 200 no longer needs to be connected to the circuit board bracket 100 by welding, gluing or separate bolts, which simplifies the installation operation of the circuit board 200 and makes it convenient to install and remove the camera decorative ring 300 and the circuit board 200 through the fastener 400.

[0017] Furthermore, the fastener 400 is a conductive structure, and the camera decorative ring 300 is electrically connected to the circuit board 200 through the fastener 400. Optionally, the fastener 400 simultaneously connects the circuit board bracket 100, the camera decorative ring 300, and the circuit board 200. The fastener 400 extends into the third connecting hole 200a, enabling the fastener 400 to contact the circuit board 200. The fastener 400 can be a conductive metal structure, specifically carbon steel, stainless steel, etc. In this way, the fastener 400 simultaneously contacts both the camera decorative ring 300 and the circuit board 200, enabling the camera decorative ring 300 to be electrically connected to the circuit board 200 through the fastener 400.

[0018] In this embodiment, the camera decorative ring 300, the circuit board bracket 100, and the circuit board 200 are connected by fasteners 400 to achieve relative fixation of the three, and the camera decorative ring 300 is electrically connected to the circuit board 200 through the conductive fasteners 400, thereby grounding the camera decorative ring 300.

[0019] In this way, the camera decorative ring 300 can be installed and grounded using only the fastener 400. That is to say, grounding is achieved directly using the component that installs the camera decorative ring 300, eliminating the need for a separate grounding point for the camera decorative ring 300 and the need for grounding springs and conductive plates on the circuit board bracket 100, which simplifies the grounding structure. Moreover, since the camera decorative ring 300 and the circuit board bracket 100 are locked together by the fastener 400, the camera decorative ring 300 is less likely to float, eliminating the need for adhesive to suppress floating. The fastener 400 can be tightened as needed to install and remove the camera decorative ring 300 without pulling or damaging the camera decorative ring 300 and the circuit board bracket 100, which simplifies maintenance and disassembly operations.

[0020] In one optional embodiment, the fastener 400 includes a fastening cap 410 and a fastening body 420 connected together. The fastening cap 410 is located at the end of the fastening body 420. The fastening body 420 passes through the first connecting hole 300a and the second connecting hole 100a in sequence and extends into the third connecting hole 200a. The fastening cap 410 protrudes from the surface of the camera decorative ring 300.

[0021] In another embodiment, the first connecting hole 300a is a countersunk hole, and the fastening cap 410 extends into the countersunk hole and abuts against the hole wall along the axial direction of the fastener 400. Specifically, the hole wall of the countersunk hole is a stepped surface, and the fastening cap 410 abuts against the stepped surface. The countersunk hole includes a first through hole and a second through hole that are connected. The diameter of the first through hole is larger than the diameter of the second through hole. The fastening cap 410 extends into the first through hole, and the fastening body 420 passes through the second through hole.

[0022] With this configuration, the first connecting hole 300a is set as a countersunk hole, allowing the fastening cap 410 of the fastener 400 to extend into the first connecting hole 300a. This prevents the fastening cap 410 from protruding from the surface of the camera decorative ring 300 and thus affecting the installation of components such as the camera lens 810 within the camera decorative ring 300. This ensures that all components of the camera module are installed smoothly, and the fastener 400 can be easily hidden in appearance, which is beneficial to improving the appearance performance.

[0023] Optionally, the electronic device also includes a camera lens 810, which is located on the side of the camera decorative ring 300 facing away from the circuit board support 100. The camera lens 810 is disposed on the camera decorative ring 300 and is connected to the camera decorative ring 300 by a connecting adhesive 811.

[0024] In one alternative embodiment, the number of fasteners 400 is one.

[0025] In another embodiment, reference Figure 1As shown, there are multiple fasteners 400, which are spaced apart. The camera decorative ring 300 is electrically connected to the circuit board 200 through each fastener 400. Optionally, the fasteners 400 are spaced apart along the direction extending from the edge of the camera decorative ring 300, specifically they can be evenly distributed or unevenly distributed.

[0026] In this embodiment, the number of fasteners 400 is increased, and different positions of the camera decorative ring 300 are connected to different positions of the circuit board bracket 100 through different fasteners 400, which helps to improve the installation stability of the camera decorative ring 300. At the same time, different positions of the camera decorative ring 300 are electrically connected to the circuit board 200 through different fasteners 400, which helps to improve conductivity stability and thus improve grounding stability.

[0027] In this embodiment, the camera decorative ring 300 is rectangular, and there are four fasteners 400 located at the corners of the rectangular structure. Of course, in other embodiments, the camera decorative ring 300 can be of other shapes, and the number of fasteners 400 can be different.

[0028] In an optional embodiment, one of the circuit board support 100 and the camera decorative ring 300 is provided with a first protrusion structure 110, which abuts against the other of the circuit board support 100 and the camera decorative ring 300 along the direction of the axis of the fastener 400. Specifically, the circuit board support 100 is provided with the first protrusion structure 110, which abuts against the camera decorative ring 300; or, the camera decorative ring 300 is provided with the first protrusion structure 110, which abuts against the circuit board support 100.

[0029] The first protrusion structure 110 can be a block protrusion or a strip protrusion. The specific shape of the first protrusion structure 110 is not limited in the embodiments of this application.

[0030] In this embodiment, the first protrusion structure 110 is used to make the circuit board bracket 100 abut against the camera decorative ring 300, which helps to reduce the gap between the circuit board bracket 100 and the camera decorative ring 300, increase the axial fastening force of the fastener 400, and improve the reliability of the threaded connection.

[0031] In an optional embodiment, one of the circuit board support 100 and the circuit board 200 is provided with a second protrusion structure 120, which abuts against the other of the circuit board support 100 and the circuit board 200 along the direction of the axis of the fastener 400. Specifically, the circuit board support 100 is provided with the second protrusion structure 120, which abuts against the circuit board 200; or, the circuit board 200 is provided with the second protrusion structure 120, which abuts against the circuit board support 100.

[0032] The second protrusion structure 120 can be a block protrusion or a strip protrusion. The specific shape of the second protrusion structure 120 is not limited in the embodiments of this application.

[0033] In this embodiment, the second protrusion structure 120 is used to make the circuit board support 100 and the circuit board 200 abut against each other, which helps to reduce the gap between the circuit board support 100 and the circuit board 200, increase the axial fastening force of the fastener 400, and further improve the reliability of the threaded connection.

[0034] Of course, in other embodiments, one of the circuit board support 100 and the camera decorative ring 300 may not have the first protrusion structure 110, and one of the circuit board support 100 and the circuit board 200 may not have the second protrusion structure 120.

[0035] In a further embodiment, at least one of the first protrusion structure 110 and the second protrusion structure 120 is a strip structure, and at least one of the first protrusion structure 110 and the second protrusion structure 120 extends along the axis surrounding the fastener 400.

[0036] Optionally, either the first protruding structure 110 or the second protruding structure 120 may be a strip structure, or both the first protruding structure 110 and the second protruding structure 120 may be strip structures. Further, the first protruding structure 110 and the second protruding structure 120 may be annular structures. Both the first protruding structure 110 and the second protruding structure 120 are arranged around the axis of the fastener 400, and the second connecting hole 100a passes through the first protruding structure 110 and the second protruding structure 120.

[0037] In this embodiment, the extension length of at least one of the first protrusion structure 110 and the second protrusion structure 120 is increased in the direction surrounding the axis of the fastener 400. This increases the area where the circuit board support 100 abuts against the camera decorative ring 300 through the first protrusion structure 110, and / or the area where the circuit board support 100 abuts against the circuit board 200 through the second protrusion structure 120. This is beneficial to further improve the axial fastening force of the fastener 400 and further improve the reliability of the threaded connection.

[0038] In this embodiment, the circuit board support 100 is provided with a first protrusion structure 110 and a second protrusion structure 120, and the material of the first protrusion structure 110 and the second protrusion structure 120 can be plastic.

[0039] In an optional embodiment, refer to Figure 2 As shown, the third connecting hole 200a is a threaded hole, and the fastener is threadedly engaged with the third connecting hole 200a.

[0040] In this embodiment, the fastener 400 and the circuit board 200 are threaded together, which helps to increase the connection area between the fastener 400 and the circuit board 200, improve the connection stability between the fastener 400 and the circuit board 200, and facilitate stable contact between the fastener 400 and the circuit board 200. This also helps to ensure a stable electrical connection between the camera decorative ring 300 and the circuit board 200 through the fastener 400, and improves grounding stability.

[0041] In the scheme of this application, reference is made to Figure 2 As shown, the electronic device also includes a cover 500, which can be a battery cover. The cover 500 and the camera decorative ring 300 are both located on the same side of the circuit board support 100, with the cover 500 positioned between the circuit board support 100 and the camera decorative ring 300. Optionally, the electronic device includes a frame 900, with the cover 500 disposed on the frame 900, opposite to the circuit board support 100, and the cover 500 used to mount the camera decorative ring 300. Specifically, the cover 500 has a through hole 500a, and the camera decorative ring 300 is located at the through hole 500a. Optionally, the camera decorative ring 300 can be a square ring, and the through hole 500a can be a square hole; alternatively, the camera decorative ring 300 can be a circular ring, and the through hole 500a can be a circular hole. In short, the shape of the camera decorative ring 300 matches the shape of the through hole 500a.

[0042] With this configuration, under the fastening action of the fastener 400, the camera decorative ring 300 will directly apply a resisting force to the cover 500, achieving an interference fit between the camera decorative ring 300 and the cover 500. At the same time, the cover 500 will directly apply a pressing force to the circuit board bracket 100, which helps to reduce the gap between the camera decorative ring 300 and the cover 500, reduce the gap between the cover 500 and the circuit board bracket 100, and improve the sealing performance.

[0043] Furthermore, the camera decorative ring 300 does not require a skirt structure to extend between the cover 500 and the circuit board support 100, thus eliminating the need for separate skirt structures to seal the cover 500 and the circuit board support 100. This simplifies the structure of the camera decorative ring 300, improves the utilization of internal space in the electronic device, and simplifies the sealing connection operation. Additionally, since the camera decorative ring 300 and its skirt structure are typically made of metal, eliminating the skirt structure does not affect the antenna signal transmission of the electronic device, thus optimizing the antenna clearance environment.

[0044] In an optional embodiment, refer to Figure 2 As shown, the camera decorative ring 300 includes a first decorative ring portion 310 and a second decorative ring portion 320 connected together. The first decorative ring portion 310 is located on the side of the cover 500 facing away from the circuit board support 100. The first decorative ring portion 310 protrudes from the outer surface of the second decorative ring portion 320. The second decorative ring portion 320 extends into the through hole 500a and protrudes from the surface of the first decorative ring portion 310 facing the circuit board support 100. Along the axial direction of the fastener 400, the first decorative ring portion 310 presses against the cover 500.

[0045] Optionally, the first decorative ring portion 310 and the second decorative ring portion 320 can be an integral structure or a separate structure, and the two can be connected by means of adhesive bonding or other methods.

[0046] In this embodiment, under the fastening action of the fastener 400, the first decorative ring portion 310 of the camera decorative ring 300 presses against the cover body 500. At the same time, the second decorative ring portion 320 extends into the through hole 500a. The second decorative ring portion 320 and the hole wall surface of the through hole 500a achieve a limiting fit to limit the camera decorative ring 300 and prevent the camera decorative ring 300 from shifting relative to the cover body 500, which helps to improve the pressing stability of the camera decorative ring 300.

[0047] Of course, in other embodiments, the second decorative ring portion 320 of the camera decorative ring 300 may not extend into the through hole 500a.

[0048] In a further embodiment, reference is made to... Figure 2 As shown, the electronic device also includes a flexible seal 600, which is disposed between the cover 500 and the camera decorative ring 300 and along the axial direction of the fastener 400. The camera decorative ring 300 is pressed against the cover 500 by the flexible seal 600, and the flexible seal 600 is in contact with both the cover 500 and the camera decorative ring 300.

[0049] Optionally, the flexible seal 600 can be made of materials with flexible properties such as rubber and silicone. The flexible seal 600 can be a sealing strip, sealing ring, or other structures. The embodiments of this application do not limit the specific structure of the flexible seal 600.

[0050] In this embodiment, by adding a flexible sealing element 600 to seal the gap between the cover 500 and the camera decorative ring 300, the sealing performance and waterproof performance are further improved.

[0051] Of course, in other embodiments, the electronic device may not have the flexible seal 600, and the camera decorative ring 300 may be directly pressed against the cover 500.

[0052] In a further embodiment, the flexible seal 600 extends along the edge of the camera decorative ring 300. Optionally, the flexible seal 600 may be a sealing strip extending along the edge of the camera decorative ring 300; or, the flexible seal 600 may be a sealing ring surrounding the camera decorative ring 300, the shape of which is adapted to the shape of the camera decorative ring 300.

[0053] In this embodiment, the flexible seal 600 extends to a larger area along the edge of the camera decorative ring 300, resulting in a larger sealing area. This is beneficial for sealing the gaps between different positions of the camera decorative ring 300 and the cover 500, and further improves the sealing performance.

[0054] In an optional embodiment, the flexible seal 600 includes a first flexible sealing portion 610 and a second flexible sealing portion 620 connected together. The first flexible sealing portion 610 is disposed between the first decorative ring portion 310 and the cover 500, and the second flexible sealing portion 620 is disposed between the second decorative ring portion 320 and the cover 500. Along the axial direction of the fastener 400, the first decorative ring portion 310 is pressed against the cover 500 by the first flexible sealing portion 610. That is, along the axial direction of the fastener 400, the first flexible sealing portion 610 seals the gap between the first decorative ring portion 310 and the cover 500, and along the radial direction of the fastener 400, the second flexible sealing portion 620 seals the gap between the second decorative ring portion 320 and the cover 500.

[0055] Optionally, the first flexible sealing part 610 and the second flexible sealing part 620 can be an integral structure or a separate structure, and the two can be connected by welding or other means; the first flexible sealing part 610 and the second flexible sealing part 620 are respectively arranged around the camera sealing ring.

[0056] In this embodiment, the flexible seal 600 can not only seal the gap between the first decorative ring portion 310 and the cover 500, but also seal the gap between the second decorative ring portion 320 and the cover 500, thereby achieving sealing of the gap between the camera decorative ring 300 and the cover 500 in the axial and radial directions of the fastener 400, which is beneficial to further improve the sealing performance.

[0057] Of course, in other embodiments, the camera decorative ring 300 may not have the second flexible sealing part 620, and the gap between the cover 500 and the camera decorative ring 300 may be sealed only by the first flexible sealing part 610 in the axial direction of the fastener 400.

[0058] In a further embodiment, the electronic device further includes a buffer 700, with a first gap between the second decorative ring portion 320 and the circuit board support 100, and the buffer 700 disposed within the first gap. Optionally, the buffer 700 may be, but is not limited to, foam, and may also be other materials with cushioning effect.

[0059] In this embodiment, since the second decorative ring portion 320 extends into the through hole 500a, the distance between the second decorative ring portion 320 and the circuit board support 100 is relatively close. By setting a buffer 700 in the gap between the two, the buffer 700 buffers the impact force between the camera decorative ring 300 and the circuit board support 100, preventing the camera decorative ring 300 from colliding with the circuit board support 100 when it falls, thereby preventing the circuit board support 100 from being crushed, which is beneficial to improving the reliability of electronic devices.

[0060] Of course, in other embodiments, the electronic device may not have the buffer 700, and the size of the second decorative ring portion 320 in the axial direction of the fastener 400 may be reduced to increase the first gap and prevent the second decorative ring portion 320 from contacting and colliding with the circuit board support 100.

[0061] In this application, the electronic device further includes a cover 500, which can be a battery cover. The cover 500 and the camera decorative ring 300 are both located on the same side of the circuit board support 100, and the cover 500 is positioned between the circuit board support 100 and the camera decorative ring 300. Optionally, the electronic device includes a frame 900, with the cover 500 disposed on the frame 900, opposite to the circuit board support 100, and the cover 500 used to mount the camera decorative ring 300. Specifically, the cover 500 has a through hole 500a, and the camera decorative ring 300 is disposed at the through hole 500a.

[0062] The electronic device also includes a buffer 700, with a second gap between the cover 500 and the circuit board support 100, and the buffer 700 disposed within the second gap. Optionally, the buffer 700 may be, but is not limited to, foam, or may be other materials with cushioning effect.

[0063] In this embodiment, the impact force between the cover 500 and the circuit board support 100 is buffered by the buffer 700 to prevent the cover 500 from colliding with the circuit board support 100 when the electronic device is dropped, thereby preventing the circuit board support 100 from being crushed and improving the reliability of the electronic device.

[0064] Of course, in other embodiments, the electronic device may not have the buffer 700, and the cover 500 may directly contact the circuit board support 100.

[0065] In this embodiment, reference Figure 2 As shown, the buffer 700 includes a first buffer portion 710 and a second buffer portion 720 connected together. The first buffer portion 710 is located between the cover 500 and the circuit board support 100, and the second buffer portion 720 is located between the second decorative ring portion 320 and the circuit board support 100. This arrangement allows the camera decorative ring 300 and the cover 500 to be buffered separately by different parts of the same buffer 700, thereby preventing the camera decorative ring and the cover 500 from impacting the circuit board support 100 and ensuring the reliability of the electronic device.

[0066] In a further embodiment, the buffer 700 extends along the edge of the camera decorative ring 300. Optionally, the buffer 700 can be a strip-shaped structure with a break, extending along the edge of the camera decorative ring 300; or, the buffer 700 can be a ring-shaped structure, surrounding the decorative ring, with the shape of the buffer 700 adapted to the shape of the camera decorative ring 300.
