Abstract
Description
Technical Field
[0001] This application relates to the field of shielding covers, and particularly to a shielding cover with an upper and lower elastic sheet buckling structure. Background Art
[0002] A shielding cover is a tool used to shield electronic signals, and its function is to shield the influence of external electromagnetic waves on the internal circuit and the radiation of electromagnetic waves generated inside to the outside. Shielding covers are mainly applied in communication fields such as mobile phones and GPS.
[0003] A shielding cover usually consists of a cover body and a cover lid. The cover body is fixed on the main body of the application device, and the cover lid is clamped on the cover body through a buckling structure.
[0004] In the prior art, the cover lid and the cover body of the shielding cover are buckled through convex bumps and holes. A plurality of convex bumps are uniformly arranged circumferentially on the side surface of the cover lid, and holes are opened on the side surface of the cover body corresponding to the convex bumps. The cover lid is buckled in the holes of the cover body through the convex bumps, thereby realizing the connection between the cover lid and the cover body. However, this buckling method requires the size and position of each convex bump and hole to correspond one by one. Once the position or size error is large, the convex bump cannot be buckled in the corresponding hole. Therefore, the production accuracy requirements for the shielding cover are relatively high, and its production cost is also correspondingly increased. Utility Model Content
[0005] The main purpose of this application is to propose a shielding cover with an upper and lower elastic sheet buckling structure, aiming to solve the problem of relatively high production cost of the shielding cover.
[0006] To achieve the above object, the shielding cover with an upper and lower elastic sheet buckling structure proposed in this application includes: a cover body and a cover lid. A maintenance opening is provided on the top surface of the cover body, the cover lid covers the maintenance opening, a plurality of first spring sheets inclined outward are arranged on the top surface of the cover body corresponding to the maintenance opening, a plurality of second spring sheets inclined inward are arranged circumferentially on the side edge of the cover lid, and the second spring sheets are buckled outside the first spring sheets.
[0007] Optionally, the inclination angles of the plurality of first spring sheets and the plurality of second spring sheets are both 20° - 40°.
[0008] Optionally, the upper ends of the first spring sheets are all provided with flanges facing the inner side direction of the maintenance opening, so that the upper ends of the first spring sheets form an arc-shaped curled edge.
[0009] Optionally, the lower ends of the second spring sheets are all provided with flanges facing the outer side direction of the maintenance opening, so that the lower ends of the second spring sheets form an arc-shaped curled edge.
[0010] Optionally, the plurality of first spring sheets are integrally formed with the cover body.
[0011] Optionally, a plurality of the second spring pieces are integrally formed with the cover.
[0012] Optionally, both the maintenance opening and the cover are rectangular.
[0013] Optionally, the number of the first spring pieces is four, and the four first spring pieces are respectively distributed on the four sides of the maintenance opening; the number of the second spring pieces is greater than that of the first spring pieces, and a plurality of the second spring pieces are arranged on the four sides of the cover.
[0014] Optionally, both the housing and the cover are made of metal plates with magnetic shielding effects.
[0015] Optionally, both the housing and the cover are made by die stamping.
[0016] In the technical solution of the present application, by providing the first spring pieces inclined outward on the housing and the second spring pieces inclined inward on the cover, and by providing the arc-shaped curled edges on the first spring pieces and the second spring pieces, when the cover is pressed, the first spring pieces and the second spring pieces are mutually extruded, promoting the elastic deformation of the first spring pieces and the second spring pieces, so that the cover can be buckled on the housing; when disassembling, by adsorbing the suction cup on the surface of the cover and pulling the cover outward, the elastic deformation of the first spring pieces and the second spring pieces can be achieved, and the cover can be disassembled. At this time, the components inside the shielding cover can be repaired and replaced through the maintenance opening. This design realizes the buckling and disassembly between the cover and the housing through the elastic deformation of the first spring pieces and the second spring pieces. This method has low requirements for the position accuracy between the first spring pieces and the second spring pieces, and correspondingly reduces the requirements for the accuracy of the die for producing this shielding cover; therefore, this device has a simple structure, is convenient for assembly and disassembly, and has a low production and manufacturing cost.

[0030] In the prior art, the cover and the housing of the shielding cover are buckled through convex bumps and holes. A plurality of convex bumps are uniformly arranged circumferentially on the side surface of the cover, and holes are provided on the side surface of the housing corresponding to the convex bumps. The cover is buckled in the holes of the housing through the convex bumps, thereby realizing the connection between the cover and the housing. However, this buckling method requires the dimensions and positions of each convex bump and hole to correspond one by one. Once the position or dimension error is large, the convex bump cannot be buckled in the corresponding hole. Therefore, the precision requirements for the mold for manufacturing the shielding cover are relatively high, and its production cost is correspondingly increased.
[0031] In view of this, the present application proposes a shielding cover with an upper and lower elastic sheet buckling structure, including: a housing 1 and a cover 2. A maintenance opening 101 is provided on the top surface of the housing 1, the cover 2 covers the maintenance opening 101, a plurality of first spring sheets 102 inclined outward are provided on the top surface of the housing 1 corresponding to the maintenance opening 101, and a plurality of second spring sheets 201 inclined inward are circumferentially provided on the side edge of the cover 2, and the second spring sheets 201 are buckled on the outside of the first spring sheets 102.
[0032] In the embodiments of the present application, referring to Figures 1 to 4 , the above-mentioned shielding cover with an upper and lower elastic sheet buckling structure includes a housing 1 and a cover 2. The housing 1 is a square housing structure with an open bottom surface. A rectangular maintenance opening 101 is provided on the top surface of the housing 1, which is convenient for repairing and replacing the components inside the housing 1.
[0033] Reference Figure 2 , on the top surface of the cover body 1, four upwardly protruding first spring pieces 102 are arranged corresponding to the four sides of the maintenance port 101. The four first spring pieces 102 are respectively distributed on the four sides of the maintenance port 101. The four first spring pieces 102 are all elastic. The first spring pieces 102 all incline towards the outside of the maintenance port 101, and the inclination angle is 20° - 40°. The first spring pieces 102 are integrally formed with the cover body 1. The upper ends (outer ends, that is, the ends far from the cover body) of the first spring pieces 102 are all provided with flanges towards the inner side of the maintenance port 101, so that the upper ends of the first spring pieces 102 form an arc-shaped curled edge.
[0034] Reference Figure 2 and Figure 4 , the cover 2 is a plate-shaped part with the same shape as the maintenance port 101, and is arranged on the top surface of the cover body 1 corresponding to the maintenance port 101 for covering the maintenance port 101. A plurality of downward second spring pieces 201 are evenly arranged circumferentially around the cover 2. The number of the second spring pieces 201 is greater than the number of the first spring pieces 102. A plurality of second spring pieces 201 are arranged on the four sides of the cover 2. Each second spring piece 201 is elastic. The second spring pieces 201 all incline towards the inner side of the maintenance port 101 by 20° - 40°. The inclined second spring pieces 201 can be abutted against the first spring pieces 102. The inclination angles of the first spring pieces 102 and the second spring pieces 201 are both within 20° - 40°, so that the first spring pieces 102 and the second spring pieces 201 can better abut against each other and fit together, thereby making the connection effect between the cover 2 and the cover body 1 better. If the inclination angles of the first spring pieces 102 and the second spring pieces 201 are less than 20, the connection between the cover 2 and the cover body 1 will be unstable. If the inclination angles of the first spring pieces 102 and the second spring pieces 201 are greater than 40, it is not easy to disassemble the cover 2 and the cover body 1 after connection.
[0035] Reference Figure 2 , the second spring pieces 201 are integrally formed with the cover 2. The lower ends (outer ends, that is, the ends far from the cover) of the second spring pieces 201 are all provided with flanges towards the outer side of the maintenance port 101, so that the lower ends of the second spring pieces 201 form an arc-shaped curled edge, enabling each second spring piece to smoothly buckle on the outside of the corresponding first spring piece, thereby enabling the cover to buckle on the cover body and cover the maintenance port.
[0036] Both the cover body 1 and the cover 2 are made of metal plates with magnetic shielding effects. The metal plates can be made of materials such as stainless steel, aluminum alloy, and cupronickel. By transmitting the metal plate into the mold for stamping, the metal plate is bent into the cover body 1 and the cover 2.
[0037] When the device is in use, the cover body 1 covers the outside of the component to be shielded, and the cover 2 covers the outside of the maintenance port 101. By clamping the inwardly inclined second spring piece 201 outside the outwardly inclined first spring piece 102, the cover 2 is buckled with the cover body 1. Therefore, when manufacturing the cover body 1 and the cover 2, the dimensional accuracy requirements for the cover 2, the cover body 1, the maintenance port 101, the first spring piece 102, and the second spring piece 201 do not need to be too high. As long as the cover 2 and the cover body 1 can be buckled together, it can be used, making the precision requirements for the mold for manufacturing the cover body 1 and the cover 2 not high, thus reducing the manufacturing cost of the mold.
[0038] The technical solution of this application is to set an outwardly inclined first spring piece on the cover body and an inwardly inclined second spring piece on the cover. The circular arc-shaped edges on the first spring piece and the second spring piece are provided so that when the cover is pressed, the first spring piece and the second spring piece are squeezed against each other, promoting the elastic deformation of the first spring piece and the second spring piece, enabling the cover to be buckled on the cover body; when disassembling, by adsorbing the suction cup on the surface of the cover and pulling the cover outward, the elastic deformation of the first spring piece and the second spring piece can be achieved, and the cover can be disassembled. At this time, the components inside the shield can be repaired and replaced through the maintenance port. This design realizes the buckling and disassembly between the cover and the cover body through the elastic deformation of the first spring piece and the second spring piece. This method has low requirements for the positional accuracy between the first spring piece and the second spring piece, and correspondingly reduces the precision requirements for the mold for producing this shield; therefore, this device has a simple structure, is convenient for disassembly and assembly, and has a low production and manufacturing cost.
[0039] The above are only optional embodiments of this application, and do not limit the patent scope of this application accordingly. All equivalent structural transformations made under the inventive concept of this application by using the content of the specification and drawings of this application, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of this application.
