Description

Technical Field

[0001] This utility model relates to the field of button technology, specifically to a button structure that can be easily disassembled and fitted with a metal-coated backing. Background Technology

[0002] The existing protective case button structure mainly includes a button shell, a spring piece set below the button shell, and a base for supporting the spring piece and the button shell. The spring piece is fixed on the base, and then the button shell is connected to the spring piece. Alternatively, the button and the protective case are integrated, or the protective case directly presses the soft rubber button.

[0003] However, existing button structures typically use screws, riveting, and plug-in welding to fix the spring to the main body of the shell to complete the function. This is costly, and the assembly process is complicated. It is also inconvenient to disassemble and reassemble during maintenance. If the button is made of soft rubber material and the button hole in the shell is interference-fitted, the cost can be reduced by pressing the interference fit during assembly. However, the appearance and material selection of the button will be limited by the type of material, which has certain limitations. Utility Model Content

[0004] The purpose of this invention is to provide a button structure that allows for easy disassembly and assembly of metal-coated buttons, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a button structure with easily detachable and removable metal coating, comprising a metal button body and a coating assembly. The metal button body is provided with an outer shell body. The coating assembly is disposed at the end of the metal button body, and the coating assembly includes a button coating groove, a coating sleeve, and a coating snap-fit ​​part. A button coating groove is provided on the outer side of one end of the metal button body, and a coating sleeve is fitted on one side of the metal button body. The end of the coating sleeve is provided with a coating snap-fit ​​part.

[0006] Furthermore, the cross-section of the rubber sleeve is C-shaped, and the outer side of one end of the rubber sleeve is flush with the outer side of the middle part of the metal button body.

[0007] Furthermore, the button coating groove is annular, and the button coating groove matches the coating snap-fit ​​part.

[0008] Furthermore, an assembly component is provided in the middle of the outer shell body, and the assembly component includes an assembly hole and a button assembly slot. The assembly hole is provided in the middle of the outer shell body, and the button assembly slot is provided on the outer side of the middle of the metal button body.

[0009] Furthermore, the cross-section of the metal button body is T-shaped, and the width of the middle part of the metal button body is smaller than the width of the mounting hole.

[0010] Furthermore, the assembly assembly also includes a rubber-coated limiting part and a movable groove. The rubber-coated sleeve has a rubber-coated limiting part in the middle of its outer side, and the outer shell body has a movable groove in the middle of one side.

[0011] Furthermore, the width of the rubber-coated limiting part is greater than the width of the assembly hole, and the outer side of the rubber-coated limiting part is arc-shaped.

[0012] Furthermore, the movable groove is elongated, and its width is greater than the width of the metal button body.

[0013] This utility model provides a button structure that allows for easy disassembly and assembly of metal-coated buttons, and has the following advantages:

[0014] 1. This utility model, through the setting of the rubber sleeve, since the button is composed of a metal button body and an LSR material rubber sleeve to form a rubber-molded structure, during the assembly process, the flexible rubber sleeve is used to achieve an interference fit to assemble the metal button body and the outer shell body. This improves the convenience of button assembly and disassembly, without limiting the material of the metal button body, making it easy to make various styles of appearance, increasing the scope of button use. In addition, during use, compared with the existing mobile phone or tablet main buttons which are mostly made of metal materials, there is a possibility of damage to the main button after prolonged friction with hard materials. This application uses a flexible rubber sleeve to contact the outer shell body, thereby reducing the possibility of friction and impact damage, and also greatly improving the button feel.

[0015] 2. By setting up a button coating groove, this utility model can prevent the coating sleeve from rubbing off during the coating process of injection molding, hydraulic or liquid molding. The coating groove and the coating snap-fit ​​part can prevent the coating sleeve from rubbing off and reduce the risk of delamination. Before coating, the hardware parts will also be treated with glue to make the soft rubber coating process more stable and effectively prevent the situation of delamination and delamination.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1 to 5 As shown, a button structure with easily detachable and assembleable metal coating includes a metal button body 1 and a coating component 3. The metal button body 1 has an outer shell body 2. The coating component 3 is located at the end of the metal button body 1 and includes a button coating groove 301, a coating sleeve 302, and a coating snap-fit ​​part 303. A button coating groove 301 is formed on the outer side of one end of the metal button body 1, and a coating sleeve 302 is fitted onto one side of the metal button body 1. A coating snap-fit ​​part 303 is provided at the end of the coating sleeve 302. The cross-section of the coating sleeve 302 is C-shaped, and the outer side of one end of the coating sleeve 302 is flush with the outer side of the middle of the metal button body 1. Since the button is composed of a metal button body 1 and a LSR material coating sleeve 302 forming a coated molding structure... Therefore, during the assembly process, a flexible rubber sleeve 302 is used to achieve an interference fit between the metal button body 1 and the outer shell body 2. This improves the ease of button assembly and disassembly without limiting the material of the metal button body 1, allowing for various styles of appearance and expanding the button's application range. During use, the flexible rubber sleeve 302 contacts the outer shell body 2 and internal electronic components, reducing the possibility of friction and damage, and significantly improving the button's feel. The button rubber sleeve groove 301 is annular and matches the rubber sleeve locking part 303. During the rubber sleeve process, the rubber sleeve groove 301 and the rubber sleeve locking part 303 prevent the rubber sleeve 302 from rubbing off, reducing the risk of glue separation.

[0024] like Figure 2As shown, an assembly component 4 is provided in the middle of the outer shell body 2, and the assembly component 4 includes an assembly hole 401 and a button assembly groove 402. The assembly hole 401 is provided in the middle of the outer shell body 2, and the button assembly groove 402 is provided on the outer side of the middle of the metal button body 1. The cross-section of the metal button body 1 is T-shaped, and the width of the middle part of the metal button body 1 is smaller than the width of the assembly hole 401. The metal button body 1 can slide within the assembly hole 401. The assembly component 4 also includes a rubber-coated limiting part 403 and a movable groove 404. The rubber-coated sleeve 302 is provided in the middle of the outer side, and the movable groove 404 is provided in the middle of one side of the outer shell body 2. The width of 03 is greater than the width of the mounting hole 401, and the outer side of the rubber-coated limiting part 403 is arc-shaped. When assembling the metal button body 1 and the outer shell body 2, the rubber-coated sleeve 302 is simply inserted into the mounting hole 401. At this time, the rubber-coated limiting part 403 will deform to avoid it. After passing through the mounting hole 401, the rubber-coated limiting part 403 can limit the other end of the metal button body 1 to prevent it from falling off. The movable groove 404 is long and narrow, and the width of the movable groove 404 is greater than the width of the metal button body 1. The movable groove 404 allows the button to have a certain amount of space to move, so as to realize the pressing function of the main body such as mobile phone or tablet.

[0025] In summary, this easily detachable, rubber-coated button structure, when used, first according to... Figures 1 to 5 The structure shown, during the encapsulation process using injection molding, hydraulic pressing, or liquid molding, first applies adhesive to the metal parts to ensure stable adhesion during the soft rubber encapsulation process, effectively preventing detachment and separation. Simultaneously, the encapsulation groove 301 and the encapsulation snap-fit ​​part 303 prevent the encapsulation sleeve 302 from rubbing off, reducing the risk of separation. Then, when assembling the metal button body 1 and the outer shell body 2, simply insert the encapsulation sleeve 302 forcefully into the assembly hole 401. At this time, the encapsulation limiting part 403 will deform to avoid this. After passing through the mounting hole 401, the rubber-coated limiting part 403 can limit the other end of the metal button body 1 to prevent it from falling off. Finally, when pressed, the button mounting groove 402 and the mounting hole 401 can slide, and the movable groove 404 allows the metal button body 1 to have a certain amount of room to move, thereby meeting normal use requirements. In addition, during the pressing and resetting process, the flexible rubber sleeve 302 makes contact with the outer shell body 2 and the internal electronic components of the device, thereby reducing the possibility of friction and damage, and also greatly improving the button feel.
