Description
Technical Field
[0001] This utility model relates to the field of electrostatic discharge technology, and in particular to an anti-static structure for metal buttons and electronic products. Background Technology
[0002] In VR electronic product design, to achieve aesthetics and a better user experience, more and more buttons are made of metal. However, any metal without a ground return path will accumulate static charge, causing electrostatic discharge (ESD), which can damage electronic devices. Therefore, electrostatic protection is crucial in the consumer electronics industry. To reduce the hazards of static electricity, a series of measures can be taken, such as connecting the metal button to the "ground" of the motherboard in the electronic product through contact conductivity, thereby effectively preventing damage to electronic components on the motherboard due to electrostatic discharge. Regarding the above technical problems, most existing technologies use a contact-type metal button conductivity method, where the metal button 5 is in direct contact with the conductive sheet 6. During the pressing of the metal button 5, there is an issue of increased force on the metal button 5, leading to a poor user experience. Figure 1 As shown. Utility Model Content
[0003] To address the aforementioned shortcomings, the technical problem to be solved by this utility model is to provide an anti-static structure for metal buttons and an electronic product, which uses a non-contact method to achieve electrostatic discharge between the metal buttons and the conductive sheet, effectively preventing damage to electronic components, ensuring consistent pressing pressure during button pressing, and providing users with a better tactile experience.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0005] An anti-static structure for a metal button includes a motherboard, a conductive sheet, and a housing assembly assembled together. The ground on the motherboard is connected to the conductive sheet. The housing assembly includes an insulating housing and a metal button. The metal button and the conductive sheet are respectively mounted on the insulating housing. The metal button and the conductive sheet are arranged opposite to each other. A gap is provided between the metal button and the conductive sheet. The maximum value of the gap is the maximum distance for electrostatic breakdown in air.
[0006] A preferred embodiment further includes a metal main bracket, wherein the motherboard and the insulating shell are respectively fixedly connected to the metal main bracket.
[0007] In a preferred embodiment, the conductive sheet is connected to ground on the motherboard via the metal main bracket.
[0008] In a preferred embodiment, the conductive sheet and the metal main support are connected through contact.
[0009] In a preferred embodiment, the housing assembly further includes an insulating button bracket, which is fixed to the insulating housing, and the metal button is disposed on the insulating button bracket.
[0010] In a preferred embodiment, the metal button includes a grounding portion disposed on the outside of the insulating button bracket; the conductive sheet includes a grounding mating portion attached to the outer wall of the insulating button bracket, and the grounding mating portion is disposed opposite to the grounding portion.
[0011] In a preferred embodiment, the grounding part and the grounding mating part are respectively located at one end of the insulating button bracket.
[0012] In a preferred embodiment, the conductive sheet has a contact conductive portion on the side away from the grounding mating portion, and the contact conductive portion contacts the metal main support; and / or, the conductive sheet further includes a fixing portion, and the fixing portion is fixedly connected to the insulating shell.
[0013] Preferably, the insulating shell and the insulating button bracket are made of plastic.
[0014] An electronic product comprising the aforementioned anti-static structure for metal buttons.
[0015] The beneficial effects of this utility model after adopting the above technical solution are:
[0016] This invention relates to an anti-static structure for metal buttons and electronic products. The anti-static structure comprises a motherboard, a conductive sheet, and a housing assembly assembled together. The ground on the motherboard is connected to the conductive sheet. The housing assembly includes an insulating shell and a metal button. The metal button and the conductive sheet are respectively mounted on the insulating shell, positioned opposite each other, with a gap between them. The maximum gap value is the maximum distance required for electrostatic breakdown of air. When the metal button comes into contact with an object carrying a high static charge, the high electrostatic voltage instantly breaks down the air, transferring the charge to the conductive sheet, and then to the ground on the motherboard. This effectively protects electronic components from damage due to electrostatic discharge. Because there is no contact between the metal button and the conductive sheet, there is no resistance when pressing the metal button. Therefore, this invention provides consumers with a better user experience. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0029] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.
[0030] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0031] like Figures 2 to 10 As shown in the embodiments of the first aspect of this utility model, the anti-static structure of the metal button includes a main board 1, a conductive sheet 6, and a housing assembly 100 assembled together. The ground (GND) on the main board 1 is connected to the conductive sheet 6. The housing assembly 100 includes an insulating housing 3 and a metal button 5. The insulating housing 3 may be made of, but is not limited to, plastic. The metal button 5 and the conductive sheet 6 are respectively mounted on the insulating housing 3. The metal button 5 and the conductive sheet 6 are arranged opposite to each other. A gap is provided between the metal button 5 and the conductive sheet 6. The maximum value of the gap (the distance between the metal button 5 and the conductive sheet 6) is the maximum distance for electrostatic breakdown in air. This distance is used to ensure that static charge is transferred to the conductive sheet 6 in a non-contact manner.
[0032] When the metal button 5 comes into contact with an object carrying a high static charge, the high electrostatic voltage instantly breaks down the air and transfers the charge to the conductive plate 6. The charge is then transferred to the ground on the motherboard 1, achieving electrostatic discharge. Because there is no contact between the metal button 5 and the conductive plate 6, there is no resistance when pressing the metal button 5, improving the user experience. Therefore, this invention effectively transfers the static charge of the metal button 5 to the conductive plate 6 by controlling the relative distance between the conductive plate 6 and the metal button 5. The conductive plate 6 then connects to the ground of the motherboard 1, effectively preventing damage to electronic components and extending product lifespan. Furthermore, this invention has the advantages of low cost and ease of implementation.
[0033] It should be noted that the gap between the metal button 5 and the conductive sheet 6 can be zero. However, in order to facilitate the assembly of the metal button 5, the gap (distance) between the metal button 5 and the conductive sheet 6 should be greater than zero. The specific size of the gap can be set according to the actual structure, as long as it ensures that the electrostatic breakdown air is transferred to the conductive sheet 6.
[0034] like Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9As shown, in some embodiments of this utility model, the anti-static structure of the metal button further includes a metal main support 2, with the main board 1 and the insulating shell 3 respectively fixedly connected to the metal main support 2. Specifically, the main board 1 can be fixedly connected to the metal main support 2 by screws 7, and the insulating shell 3 can be fixedly connected to the metal main support 2 by screws 7.
[0035] In this invention, the conductive sheet 6 is connected to the ground on the motherboard 1 via the metal main bracket 2. Specifically, the metal main bracket 2 can be connected to the ground on the motherboard 1 via conductive components such as wires, or via contact. In a preferred embodiment, the metal main bracket 2 can be simultaneously connected and connected via screws 7. Similarly, the conductive sheet 6 and the metal main bracket 2 can be connected via contact or via conductive components such as wires.
[0036] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments of the present invention, the housing assembly 100 further includes an insulating button bracket 4, on which a metal button 5 is disposed. Specifically, the insulating button bracket 4 and the metal button 5 may be an interference fit.
[0037] The insulating button bracket 4 is fixed to the insulating housing 3. Specifically, the insulating button bracket 4 can be fixedly connected to the insulating housing 3 by screws 7. In these embodiments, the outer wall of the insulating housing 3 may be provided with a mounting through hole, and the insulating button bracket 4 is installed at the mounting through hole. In addition, the insulating button bracket 4 in this utility model may be made of, but is not limited to, plastic.
[0038] When the metal button 5 comes into contact with an object with a high static charge, the high electrostatic voltage instantly breaks down the air and transfers the charge to the conductive sheet 6. The charge is then transferred to the motherboard 1 through the metal main bracket 2 and connected to the ground on the motherboard 1, thus realizing electrostatic discharge.
[0039] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments of this utility model, the metal button 5 includes a grounding part 50, which is disposed on the outside of the insulating button bracket 4; the conductive sheet 6 includes a grounding mating part 60, which is attached to the outer wall of the insulating button bracket 4, and the grounding mating part 60 is disposed opposite to the grounding part 50; specifically, the grounding part 50 and the grounding mating part 60 are respectively disposed at one end of the insulating button bracket 4.
[0040] A contact conductive part 61 is provided on the side of the conductive sheet 6 away from the grounding mating part 60, and the contact conductive part 61 contacts the metal main support 2; and / or; the conductive sheet 6 also includes a fixing part 62, which is integrally formed with the grounding mating part 60 and the contact conductive part 61, and the fixing part 62 is fixedly connected to the insulating shell 3 by screws 7.
[0041] In this invention, the grounding mating part 60, the contact conductive part 61, and the fixing part 62 of the conductive sheet 6 are all sheet-like structures. The structure of the grounding mating part 60 is adapted to the outer wall structure of one end of the insulating button bracket 4, allowing it to adhere to the outer wall of the insulating button bracket 4 and be positioned opposite to the grounding part 50 of the metal button 5. In a preferred embodiment, the grounding part 50 and the grounding mating part 60 are perpendicularly arranged. The fixing part 62 has a mounting hole, and the insulating shell 3 has a threaded hole. A screw 7 passes through the mounting hole and the threaded hole to achieve a fixed connection between the conductive sheet 6 and the insulating shell 3. In another preferred embodiment, the contact conductive part 61 is perpendicularly arranged to the grounding mating part 60, and the grounding conductive part and the fixing part 62 are spaced apart. After the conductive sheet 6 is fixedly connected to the insulating shell 3, the contact conductive part 61 makes contact with the metal main bracket 2. Therefore, the conductive sheet 6 with the above structure achieves non-contact electrostatic discharge with the metal button 5, optimizes the overall structural layout, and makes reasonable use of space.
[0042] It should be noted that the metal button 5 only needs to be partially positioned opposite the conductive sheet 6. Of course, it can also be positioned entirely opposite the conductive sheet 6, depending on the actual structural requirements.
[0043] According to an embodiment of the second aspect of the present invention, the electronic product includes the anti-static metal button structure of the first aspect of the present invention.
[0044] The electronic products in this utility model can be, but are not limited to, VR products, AR products, etc. Any electronic product with metal buttons can use the anti-static structure of the metal buttons in the first aspect of this utility model. Because the metal buttons and conductive sheets adopt a non-contact anti-static structure, the pressure is consistent when the metal buttons are pressed, and no resistance is generated, thereby improving the user experience.
[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent anti-static structures for metal buttons, and improvements to electronic products made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
