Technical Field

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

[0002] With the diversification of electronic equipment functions and the increasing requirements for grounding performance, the reliability requirements for the internal structure of electronic equipment are getting higher and higher. The antenna is an important part of the electronic equipment. The antenna determines the communication performance of the electronic equipment. In order to achieve the best performance of the antenna, reduce clutter, and improve the radiation performance of the antenna, the grounding component needs to be electrically connected to the circuit board through the grounding spring. In addition, a reinforcement sheet is usually set on the surface of the circuit board to strengthen the strength of the circuit board and reduce the stress on the circuit board.

[0003] In the related art, the reinforcement sheet and the grounding spring sheet are respectively welded to different areas of the circuit board. The reinforcement sheet and the grounding spring sheet are close to each other. The grounding spring sheet will affect the laying area of ​​the reinforcement sheet, resulting in a smaller laying area of ​​the reinforcement sheet, which is not conducive to reducing the stress on the circuit board. Moreover, the grounding spring sheet needs to be welded to the circuit board first, and then other components of the electronic device (such as cameras, etc.) are installed. Other components are easy to scratch the grounding spring sheet during the installation process, which makes the grounding spring sheet easily deformed and damaged, resulting in poor grounding effect of the grounding component. Summary of the invention The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem in the related art that the grounding springs of the electronic device are easily deformed and damaged, resulting in poor grounding effect.

[0004] The embodiment of the present application provides an electronic device, including a circuit board, a reinforcement sheet, a grounding spring sheet and a grounding component, wherein the reinforcement sheet is arranged on the circuit board and the reinforcement sheet is attached to the circuit board, the grounding spring sheet is detachably arranged on a side of the reinforcement sheet facing away from the circuit board, and the reinforcement sheet is provided with a hollow area. The grounding component is pressed against the grounding spring sheet, and the grounding spring sheet is deformed and contacts the circuit board through the hollow area, so that the grounding component is electrically connected to the circuit board through the grounding spring sheet.

[0005] In the embodiment of the present application, the grounding spring is directly installed on the reinforcing sheet, so the grounding spring does not occupy additional space on the circuit board. Then, the laying area of ​​the reinforcing sheet is larger, which is more conducive to increasing the strength of the circuit board and reducing the stress on the circuit board. In addition, the grounding spring adopts a detachable installation method, so the electronic device can first install other components (such as cameras, etc.) and then further install the grounding spring. In this way, other components are prevented from scratching the grounding spring, and the grounding spring is prevented from deformation and damage, which is conducive to improving the grounding effect of the grounding component.

The reinforcement sheet 200 is arranged on the circuit board 100, and the reinforcement sheet 200 is attached to the circuit board 100. The reinforcement sheet 200 is used to increase the strength of the circuit board 100, reduce the stress on the circuit board 100, and avoid excessive deformation of the circuit board 100 when the force is applied. The grounding component 400 is electrically connected to the circuit board 100 through the grounding spring 300, so that the grounding component 400 is in a grounded state.

[0012] Optionally, the reinforcement sheet 200 can be adhered to the surface of the circuit board 100 by welding, bonding, etc.; the grounding component 400 can be a decorative ring of the camera 500, of course, it can also be other metal components that need to be grounded. When the grounding component 400 is installed, the grounding component 400 is pressed against the grounding spring sheet 300.

[0013] The grounding spring 300 is detachably arranged on the side of the reinforcing sheet 200 facing away from the circuit board 100. Optionally, the grounding spring 300 can be detachably mounted on the reinforcing sheet 200 by snap connection, bolt connection or other detachable methods, and the embodiment of the present application does not limit the detachable mounting method of the grounding spring 300.

[0015] refer to Fig.13 As shown, the grounding component 400 presses against the grounding spring sheet 300, and the grounding spring sheet 300 is deformed by the pressing force of the grounding component 400, and the grounding spring sheet 300 contacts the circuit board 100 through the hollow area 210a, so that the grounding component 400 is electrically connected to the circuit board 100 through the grounding spring sheet 300. Specifically, after the grounding spring sheet 300 is installed on the reinforcing sheet 200, the grounding spring sheet 300 is in Fig.12 In the state shown, the grounding component 400 is not installed at this time; when the grounding component 400 is installed, the grounding component 400 presses against the grounding spring 300, and the grounding spring 300 is in Fig.13 In the state shown, the grounding spring 300 is in contact with the copper exposed area 120 of the circuit board 100 , and the grounding component 400 is grounded through the grounding spring 300 .

[0016] In the embodiment of the present application, the grounding spring 300 is directly mounted on the reinforcing sheet 200, so the grounding spring 300 does not occupy additional space of the circuit board 100. Then, the laying area of ​​the reinforcing sheet 200 is larger, the reinforcement effect is improved, and it is more conducive to increasing the strength of the circuit board 100, avoiding deformation of the circuit board 100, and reducing the stress on the circuit board 100. In addition, the grounding spring 300 adopts a detachable installation method, so the electronic device can first install other components (such as the camera 500, etc.), and then further install the grounding spring 300, so that other components are prevented from scratching the grounding spring 300, and the grounding spring 300 is prevented from being deformed and damaged, which is conducive to improving the grounding effect of the grounding component 400 and improving the stability of the antenna; at the same time, the grounding spring 300 can be repaired and replaced separately, and when the grounding spring 300 is damaged, there is no need to replace the grounding spring 300, the reinforcing sheet 200 and the entire structure of the circuit board 100.

[0017] In an alternative embodiment, reference Figure 3 As shown, the reinforcing sheet 200 includes a first base 210, a first side wall 220 and a second side wall 230. The first base 210 may be a plate-like structure, a sheet-like structure, etc., as long as it can be attached to the circuit board 100. The first side wall 220 and the second side wall 230 are respectively connected to the first base 210, and the first side wall 220 and the second side wall 230 are opposite to each other. The first side wall 220 and the second side wall 230 are respectively protruded from the surface of the first base 210. Specifically, the first side wall 220 and the second side wall 230 are respectively protruded from the surface of the first base 210 facing away from the circuit board 100.

[0018] Optionally, the first base 210, the first side wall 220 and the second side wall 230 can be an integrally formed structure, or the first base 210, the first side wall 220 and the second side wall 230 can be a split structure. Further optionally, the first side wall 220 and the first base 210, and the second side wall 230 and the second base 310 can be connected by welding, bonding, or the like.

[0019] A space for the grounding spring 300 to extend into is formed between the first side wall 220 and the second side wall 230. The first base 210 is provided with a hollow area 210a, which is located between the first side wall 220 and the second side wall 230. The hollow area 210a can be opposite to the grounding spring 300, and the grounding spring 300 is engaged with the reinforcing sheet 200. Specifically, the grounding spring 300 is engaged between the first side wall 220 and the second side wall 230. When the grounding spring 300 extends into between the first side wall 220 and the second side wall 230, the grounding spring 300 slides in contact with the first side wall 220 and the second side wall 230, respectively.

[0020] In this embodiment, the reinforcement sheet 200 is additionally provided with a first side wall 220 and a second side wall 230, and the first side wall 220 and the second side wall 230 are utilized to limit the movement direction of the grounding spring sheet 300 relative to the reinforcement sheet 200, which is beneficial to accurately install the grounding spring sheet 300 and ensure that the grounding spring sheet 300 and the reinforcement sheet 200 are stably snap-fitted.

The bending portion 310a is bent toward one side of the reinforcing sheet 200, and the stop groove 210b can be a square groove, a circular groove, etc. The embodiment of the present application does not limit the shape of the stop groove 210b. The bending portion 310a extends into the stop groove 210b, which is the mating state when the grounding spring piece 300 is clamped between the first side wall 220 and the second side wall 230. In the process of installing the grounding spring piece 300, that is, when the grounding spring piece 300 extends between the first side wall 220 and the second side wall 230, and the bending portion 310a does not extend into the stop groove 210b, the grounding spring piece 300 generates elastic deformation, and the bending portion 310a contacts the surface of the first base 210.

[0023] In this embodiment, the stop groove 210b and the bending portion 310a are used to limit the position of the grounding spring piece 300 relative to the reinforcement sheet 200, thereby preventing the grounding spring piece 300 from moving excessively relative to the reinforcement sheet 200, and ensuring that the grounding spring piece 300 is stably clamped between the first side wall 220 and the second side wall 230.

[0024] Of course, in other embodiments, the reinforcing sheet 200 and the grounding spring sheet 300 may not be provided with the stop groove 210 b and the bending portion 310 a , and the grounding spring sheet 300 is directly clamped between the first side wall 220 and the second side wall 230 .

[0025] In an optional embodiment, the first base 210 is a single-layer structure, the first base 210 is provided with a first opening 211a and a stop groove 210b, the first side wall 220 and the second side wall 230 are arranged relatively to the edge of the first opening 211a, and the first opening 211a forms a hollow area 210a.

[0027] Moreover, the second substrate 211 is provided with a first opening 211a, the first side wall 220 and the second side wall 230 are arranged at the edge of the first opening 211a, and a hollow area 210a and a stop groove 210b are formed between the first substrate 2121 and the third substrate 2122, and the hollow area 210a and the stop groove 210b are respectively opposite to the first opening 211a. In this way, the grounding spring 300 contacts the circuit board 100 through the first opening 211a and the hollow area 210a. Fig.13 As shown, the bending portion 310a extends into the stop groove 210b through the first opening 211a, and the bending portion 310a is limitedly matched with the edge of the first opening 211a, that is, the bending portion 310a is limitedly matched with the second substrate 211.

Not only are the first substrate 2121 and the third substrate 2122 provided with the stop groove 210b respectively limited and matched with the bending portion 310a, but the second substrate 211 provided with the first opening 211a is also limited and matched with the bending portion 310a. This is beneficial to increasing the area of ​​the first base 210 and the bending portion 310a, and is more beneficial to stably limit the position of the grounding spring piece 300 relative to the reinforcement plate 200, thereby improving the clamping stability of the grounding spring piece 300.
