Description

Technical Field

[0001] This application relates to the technical field of electronic accessories, and particularly to a shielding cover, a control board, and a mobile electronic terminal. Background Art

[0002] Control boards are provided in electronic terminals such as mobile phones, tablet computers, computers, watches, etc. Chips and other necessary electronic components are integrated on the control board. Usually, in order to avoid electromagnetic interference to electronic accessories, a metal shielding cover is installed on the control board, and openings are made in the corresponding areas of the shielding cover for some chips to facilitate rapid heat dissipation of the chips or smooth signal transmission.

[0003] However, the material strength around the openings on the shielding cover is relatively low. When the electronic terminal drops, the problem of deformation of the control board is likely to occur. To improve the strength, the existing method is usually to directly increase the thickness of the entire shielding cover substrate. Although this method improves the strength of the entire shielding cover (control board) as a whole, it greatly increases the thickness and weight of the entire control board (including the shielding cover); moreover, since the thickness of the shielding cover increases, the width of the pads on the control board used for welding with the shielding cover also needs to be widened accordingly, which occupies the space of the control board to a certain extent and affects the layout of other electronic components on the control board. Summary of the Utility Model

[0004] The purpose of the embodiments of the present utility model is to provide a shielding cover, a control board, and a mobile electronic terminal, which can solve the above problems existing in the prior art.

[0005] To achieve the above object, this application adopts the following technical solutions:

[0006] On the one hand, a shielding cover is provided, including a cover plate and a sealing edge connected to the outer peripheral edge of the cover plate. An avoidance hole is provided in the cover plate, and a reinforcing frame is provided on at least one side surface of the cover plate, and the reinforcing frame is arranged around the edge of the avoidance hole.

[0007] Optionally, the reinforcing frame and the cover plate are an integral sheet metal structure.

[0008] Optionally, the reinforcing frame includes a first reinforcing piece and a second reinforcing piece. The first reinforcing piece and the cover plate are an integral sheet metal structure, and each side wall of the avoidance hole is correspondingly bent to form a first reinforcing piece; a second reinforcing piece is welded and connected between two adjacent first reinforcing pieces to form the reinforcing frame arranged around the edge of the avoidance hole.

[0009] Optionally, the side of the reinforcing frame away from the edge of the avoidance hole is welded and fixed to the cover plate.

[0010] Optionally, the reinforcing frame is welded and fixed to the cover plate.

[0011] Optionally, the width of each side frame of the reinforcing frame is not less than 2 mm.

[0012] Optionally, the thickness of the cover plate is 0.1 - 0.2 mm.

[0013] Optionally, the reinforcing frame is arranged inside the cover plate.

[0014] On the other hand, a control board is provided, which includes a control board main body and the above-mentioned shielding cover. A chip is provided on the control board main body, the shielding cover covers the control board main body, and the avoidance holes on the shielding cover are aligned with the chip.

[0015] On yet another hand, a mobile electronic terminal is provided, which includes the above-mentioned control board.

[0016] The beneficial effects of this application are as follows: The utility model provides a shielding cover, a control board and a mobile electronic terminal. A reinforcing frame is arranged on the cover plate of the shielding cover around the edge of the avoidance hole, which precisely reinforces the strength of the material around the avoidance hole by using the reinforcing frame, effectively avoiding the problem that the whole control board is prone to deformation due to insufficient strength of the material around the avoidance hole. Compared with the method of directly increasing the thickness of the whole shielding cover, the solution of the utility model only precisely reinforces the material around the avoidance hole, and the consumables of the whole shielding cover are less, reducing the weight and manufacturing cost of the shielding cover to a certain extent; in addition, since the material thickness of the shielding cover is smaller, the width of the solder pads welded to the shielding cover on the control board is smaller, so more layout space can be reserved for the control board, facilitating the layout of electronic components on the control board.

[0024] To make the technical problems solved by this application, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of the embodiments of this application will be further described in detail below. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of this application.

[0025] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific situations.

[0026] In this application, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through other features therebetween. Moreover, the first feature being "above", "above", and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "below", and "under" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0027] Control boards are provided in electronic terminals such as mobile phones, tablet computers, computers, watches, etc. Chips and other necessary electronic components are integrated on the control board. Usually, in order to avoid electromagnetic interference to electronic accessories, a metal shielding cover is installed on the control board, and openings are made in the corresponding areas of the shielding cover for the chips to facilitate the rapid heat dissipation of the chips or smooth signal transmission.

[0028] However, the material strength around the opening on the shielding cover is relatively low. When the electronic terminal drops, the problem of the control board deforming easily occurs. To improve the strength, the existing practice is usually to directly increase the thickness of the entire shielding cover substrate. Although this method improves the strength of the entire shielding cover (control board) as a whole, it greatly increases the thickness and weight of the entire control board (including the shielding cover). Moreover, since the thickness of the shielding cover increases, the width of the pads used for welding the shielding cover on the control board also needs to be widened accordingly, which occupies the space of the control board to a certain extent and affects the layout of other electronic components on the control board.

[0029] To overcome the above technical problems, as shown in Figures 1-4 This embodiment provides a shielding cover, including a cover plate 1 and a sealing edge 2 connected to the outer peripheral edge of the cover plate 1. An avoidance hole 11 is provided in the cover plate 1, and a reinforcing frame 3 is provided on at least one side surface of the cover plate 1. The reinforcing frame 3 is arranged around the edge of the avoidance hole 11.

[0030] Specifically, the shielding cover of this embodiment can be welded to the control board main body during application. The sealing edge 2 is arranged around the edge of the cover plate 1 and protrudes toward the side where the control board main body is located relative to the cover plate 1, so that the sealing edge 2 can be welded and fixed to the pads on the control board main body, and the cover plate 1 can keep a certain interval from the control board main body to cover the electronic components on the control board main body to provide shielding and protection. Preferably, the cover plate 1 and the sealing edge 2 are of an integral structure, and the structure of the cover plate 1 and the sealing edge 2 is formed by stamping a sheet material through a stamping process.

[0031] The avoidance hole 11 is set according to the specific shape and position of the chip that needs to be avoided on the control board main body. When specifically setting, one or more avoidance holes 11 can be opened on the cover plate 1. In addition, the reinforcing frame 3 can be only arranged on the periphery of some of the avoidance holes 11. For example, for the avoidance holes 11 with a smaller size, the degree of damage to the material strength of their periphery is relatively small, so the reinforcing frame 3 can be not set for strengthening, and only the reinforcing frame 3 is arranged on the periphery of the avoidance holes 11 with a larger size. To provide reliable reinforcement, the reinforcing frame 3 needs to be fixedly attached to the surface of the cover plate 1; the reinforcing frame 3 is in a frame structure adapted to the shape of the avoidance hole 11, and it is arranged around the entire periphery of the avoidance hole 11, and can achieve precise reinforcement of the material of the periphery of the avoidance hole 11.

[0032] Based on the shielding case of this embodiment, a reinforcing frame 3 is provided on the cover plate 1 of the shielding case, which is arranged around the edge of the avoidance hole 11. The reinforcing frame 3 is used to accurately reinforce the strength of the material around the avoidance hole 11, effectively avoiding the problem that the entire control board is prone to deformation due to insufficient strength of the material around the avoidance hole 11. Compared with the method of directly increasing the thickness of the entire shielding case, this solution only accurately reinforces the material around the avoidance hole 11, and the consumables of the entire shielding case are less, reducing the weight and manufacturing cost of the shielding case to a certain extent; in addition, since the material thickness of the shielding case is smaller, the width of the solder pad welded to the shielding case on the control board is smaller, so more layout space can be reserved for the control board, facilitating the layout of electronic components on the control board.

[0033] In one embodiment, the reinforcing frame 3 and the cover plate 1 are an integral sheet metal structure.

[0034] Specifically, the reinforcing frame 3 is formed by bending the material punched out from the avoidance hole 11 by sheet metal. This solution utilizes the ductility of the metal material and directly bends the material originally punched out at the position corresponding to the avoidance hole 11 on the cover plate 1 to fit onto the surface of the cover plate 1 to form the reinforcing frame 3 by sheet metal process, without the need to separately process and form the reinforcing frame 3. Obviously, this method has the advantages of easy processing and low cost. The integrated design of the reinforcing frame 3 and the cover plate 1 not only simplifies the manufacturing process but also enhances the integrity of the structure. It should be noted that since the size of the material punched out from the position of the avoidance hole 11 on the cover plate 1 is smaller than the size of the reinforcing frame 3 to be formed and the ductility of the material is limited, this method is generally applicable to the case where the width of the formed reinforcing frame 3 is smaller.

[0035] In another embodiment, referring to Figures 3-4 , the reinforcing frame 3 includes a first reinforcing piece 31 and a second reinforcing piece 32. The first reinforcing piece 31 and the cover plate 1 are an integral sheet metal structure, and each side wall of the avoidance hole 11 is bent to form a first reinforcing piece 31; a second reinforcing piece 32 is welded between two adjacent first reinforcing pieces 31 to form the reinforcing frame 3 arranged around the edge of the avoidance hole 11.

[0036] Specifically, the first reinforcing piece 31 is formed by bending the material punched out from the avoidance hole 11 by sheet metal. When the designed width of the reinforcing frame 3 is large and it cannot be directly formed by sheet metal bending, this embodiment method can be used for processing. Specifically, the material punched out at the position of the avoidance hole 11 on the cover plate 1 is divided into multiple parts to form multiple first reinforcing pieces 31, and then each first reinforcing piece 31 is bent in different directions to fit onto the surface of the cover plate 1, and then the second reinforcing piece 32 is welded to weld the multiple first reinforcing pieces 31 into a bent reinforcing frame 3 to achieve comprehensive reinforcement of the material around the avoidance hole 11.

[0037] In this way, a reinforcing frame 3 with a larger width can be obtained to provide a more reliable reinforcing structure, and it is possible to make full use of the base material for manufacturing the shielding cover, achieving the effect of reducing consumables and saving costs.

[0038] In a further embodiment, one side of the reinforcing frame 3 away from the edge of the relief hole 11 is fixedly welded to the cover plate 1.

[0039] The whole or part of the reinforcing frame 3 is formed by bending the material corresponding to the relief hole 11, so the part originally close to the edge of the relief hole 11 is integrally connected to the cover plate 1. In this embodiment, welding the side of the reinforcing frame 3 away from the edge of the relief hole 11 to the cover plate 1 can further make the connection between the reinforcing frame 3 and the cover plate 1 firm. This connection method enables the reinforcing frame 3 to better disperse and withstand external impacts and vibrations, thereby enhancing the structural stability of the entire control board.

[0040] In another embodiment, referring to Figure 1 , the reinforcing frame 3 is fixedly welded to the cover plate 1.

[0041] Specifically, the cover plate 1 and the reinforcing frame 3 in this way are separately processed and formed, and then the reinforcing frame 3 is fixedly welded to the cover plate 1. Similarly, in this way, a reinforcing frame 3 with a larger width can be obtained. By welding the whole reinforcing frame 3 to the cover plate 1, an all-round connection between the reinforcing frame 3 and the cover plate 1 is achieved. This connection method can withstand greater tensile and shear forces, thereby enhancing the stability of the entire shielding cover structure.

[0042] In one embodiment, the width of each side frame of the reinforcing frame 3 is not less than 2 mm.

[0043] Controlling the width of each side of the reinforcing frame 3 to be above 2 mm, the support and protection effects provided by it will be more significant, and it can better meet the usage requirements of the control board.

[0044] In one embodiment, the thickness of the cover plate 1 is 0.1 - 0.2 mm.

[0045] As part of the control board, the thickness of the cover plate 1 directly affects the weight of the entire product. With the reinforcement of the reinforcing frame 3 provided in this solution, setting the thickness of the cover plate 1 within the range of 0.1 - 0.2 mm realizes the lightweight design of the product while providing sufficient reliability.

[0046] Preferably, the thickness of the cover plate 1 is 0.15 mm.

[0047] In one embodiment, the reinforcing frame 3 is disposed inside the cover plate 1.

[0048] Specifically, in application, the side of the cover plate 1 facing the surface of the control board main body is the inner side, and the side exposed to the environment is the outer side.

[0049] Placing the reinforcing frame 3 inside also helps to optimize the overall layout of the control board and avoid the convexity of the reinforcing frame 3 from affecting the installation of other structural components in the product during application.

[0050] On the other hand, the present embodiment also provides a control board, including a control board main body and the above-mentioned shielding cover. A chip is provided on the control board main body, the shielding cover covers the control board main body, and the avoidance hole 11 on the shielding cover is aligned with the chip.

[0051] Specifically, a chip and other necessary electronic components are provided on the control board main body. The sealing edge 2 at the periphery of the shielding cover is welded and fixed to the control board main body. For the chips that need to be cleared, avoidance holes 11 are correspondingly provided on the shielding cover, so that the chips can dissipate heat smoothly or receive and transmit radio signals.

[0052] Based on the shielding cover of the present embodiment, the control board of the present embodiment has the advantages of low cost, good reliability, convenient design layout, etc.

[0053] On yet another aspect, the present embodiment provides a mobile electronic terminal, including the above-mentioned control board.
