Description

Technical Field

[0001] This utility model relates to the field of button technology, specifically to a button back structure. Background Technology

[0002] A button is a mechanical switch that connects the circuit when pressed and disconnects it when released. Due to the presence of a pull-up resistor, it is usually at a low level when pressed and at a high level when released. Buttons can close the circuit through physical contact. Common types include mechanical buttons, membrane buttons, and touch buttons.

[0003] A novel button structure, as disclosed in Chinese Utility Model Patent Publication No. CN214797197U, includes a button bracket, a button cap, and a button decorative ring. A conductive cross-shaped rib is fixed to the lower side of the button bracket, a button cap is provided inside the button bracket, and a button decorative ring is provided on the upper side of the button bracket. The back of the button decorative ring mates with the top of the button bracket, leaving a gap between them. Compared with existing technologies, the advantages are: the button bracket and button decorative ring of this utility model are respectively provided with positioning hole one and positioning hole two, and positioning hole one and positioning hole two correspond to each other. Positioning hole one and positioning hole two each include two round holes and one square hole. Combined with the limiting block structure on the button cap, this ensures unique button installation and prevents the power symbol on the button from being installed skewed; the button structure of this novel design prevents button jamming; and the button structure of this novel design is more aesthetically pleasing, with better tactile feedback and pressing balance.

[0004] Buttons transmit operation commands through physical structures, reducing the steps of acquiring electrical signals, thus making them more reliable. In addition, buttons are more durable and stable in scenarios requiring frequent operation or high-intensity use. However, existing buttons are too thick, which causes users to apply too much pressure during use, resulting in a poor feel. This not only reduces the user experience but also affects the button's performance. Utility Model Content

[0005] The purpose of this utility model is to provide a button back structure to solve the problems mentioned in the background art, such as the button thickness being too thick, the pressing force being too large, the feel being poor, and the user experience being bad.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A key back structure includes a base plate, keycaps, and a force-distributing assembly; a plurality of keycaps are evenly disposed on the base plate via a sliding mechanism; the force-distributing assembly is arranged on the keycaps; the force-distributing assembly includes a dispersing groove and a force-receiving groove; the keycaps have dispersing grooves around their perimeter; and the dispersing grooves have force-receiving grooves inside them.

[0008] Preferably, the keycap thickness is 1.5 mm.

[0009] Preferably, the dispersion groove has an isosceles trapezoidal cross-section and the opening of the dispersion groove faces outward.

[0010] Preferably, the cross-section of the force-receiving groove is an arc-shaped structure, and the starting end of the force-receiving groove is located away from the direction of the dispersion groove.

[0011] Preferably, it also includes a noise reduction component; the noise reduction component is arranged inside the keycap.

[0012] Preferably, the noise reduction assembly includes a receiving groove and a noise reduction plate; the receiving groove is provided inside the keycap; and a plurality of the noise reduction plates are fixed in a linear array within the receiving groove.

[0013] Preferably, the sound-absorbing plate has a sawtooth structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by setting a force-distributing component, allows the keycap to transfer the pressure received by the user to the dispersion groove when the user presses the keycap. Since the dispersion groove has an isosceles trapezoidal cross-section, it can concentrate and transfer the pressure to the force-receiving groove, allowing the force-receiving groove to buffer the pressure. Since the force-receiving groove has an arc-shaped cross-section, it can improve the pressure-bearing effect of the force-receiving groove, thereby improving the durability of the keycap. Compared with the prior art, this utility model has a simple and reasonable structure and ingenious design. By removing the partition layer, the silicone structure and the spring are directly combined and installed, reducing the thickness of the keycap, reducing the load, and improving the feel, resulting in a better user experience.

[0016] 2. This utility model, by setting a noise reduction component, generates sound due to vibration and collision when the user's fingers come into contact with the keycaps. The sound is transmitted through the keycaps to the receiving groove and acts on the noise reduction plate. Since the noise reduction plate has a sawtooth structure, it can repeatedly refract the sound waves, thereby reducing the sound generated when the user's fingers come into contact with the keycaps, thus achieving a silent effect and improving the user's comfort.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a key back structure, including a base plate 1, keycaps 2, and force-distributing components 3; a plurality of keycaps 2 are evenly disposed on the base plate 1 by a sliding mechanism; the force-distributing components 3 are arranged on the keycaps 2; the force-distributing components 3 include a dispersion groove 301 and a force-receiving groove 302; the dispersion groove 301 is formed around the keycaps 2; the force-receiving groove 302 is formed inside the dispersion groove 301; the keycaps 2 are 1.5 mm thick, while the normal keycaps 2 are 3 mm thick. By reducing the thickness of the keycaps 2, the feel and experience are improved; the dispersion groove 301 has an isosceles trapezoidal cross-section, and the opening of the dispersion groove 301 faces outward; the force-receiving groove 302 has an arc-shaped cross-section, and the arc-shaped end of the force-receiving groove 302 is positioned away from the dispersion groove 301.

[0026] This invention, by setting a force-sharing component 3, allows the keycap 2 to transmit the pressure received when the user presses it to the dispersion groove 301. Since the dispersion groove 301 has an isosceles trapezoidal cross-section, it can concentrate and transmit the pressure to the force-receiving groove 302, which can buffer the pressure. The force-receiving groove 302 has an arc-shaped cross-section, which improves its pressure-bearing capacity and thus enhances the durability of the keycap 2. Compared with the prior art, this invention has a simple and reasonable structure and ingenious design. By removing the spacer layer, the silicone structure and the spring are directly combined and installed, reducing the thickness of the keycap 2, reducing the load, and improving the feel and performance.

[0027] As a preferred embodiment, it also includes a noise reduction component 4; the noise reduction component 4 is arranged inside the keycap 2; the noise reduction component 4 includes a receiving groove 401 and a noise reduction plate 402; the receiving groove 401 is provided inside the keycap 2; three noise reduction plates 402 are fixedly connected in a linear array inside the receiving groove 401; the noise reduction plate 402 has a sawtooth structure.

[0028] This invention incorporates a noise-dampening component 4. When a user's finger comes into contact with the keycap 2, vibration and impact will generate sound. The sound will be transmitted through the keycap 2 to the receiving groove 401 and act on the noise-dampening plate 402. Since the noise-dampening plate 402 has a serrated structure, it can repeatedly refract sound waves, thereby reducing the sound generated when the user's finger comes into contact with the keycap 2, achieving a silent effect and improving user comfort.

[0029] Working principle: When the user presses the keycap 2, the keycap 2 transmits the pressure to the dispersion groove 301. Since the dispersion groove 301 has an isosceles trapezoidal cross-section, it can concentrate and transmit the pressure to the force-receiving groove 302, which can buffer the pressure. Since the force-receiving groove 302 has an arc-shaped cross-section, it can improve the pressure-bearing effect of the force-receiving groove 302, thereby improving the durability of the keycap 2. When the user's fingers come into contact with the keycap 2, the vibration and collision will produce sound. The sound will be transmitted through the keycap 2 to the receiving groove 401 and act on the sound-absorbing plate 402. Since the sound-absorbing plate 402 has a serrated structure, it can repeatedly refract the sound waves, thereby reducing the sound generated when the user's fingers come into contact with the keycap 2, thus achieving a silent effect and improving the user's comfort.

[0030] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
