Description

Technical Field

[0001] This utility model relates to the field of keyboard key technology, specifically to a keyboard key with silent buffer. Background Technology

[0002] A keyboard is an input device used to input instructions and data into a computer or other electronic device. It consists of a set of keys, each with a specific function, which users can press to input characters, numbers, and instructions.

[0003] Announcement No.: CN213093101U, entitled "Keyboard Key Structure," describes a keyboard key structure comprising a lower housing, an upper housing, a pressing shaft, and a spring. The lower housing has a base with two hooks extending upwards from it. The upper housing has a top wall, an annular peripheral wall surrounding the top wall, and a through-hole on the top wall. The upper housing also has two through-hole slots on either side of the through-hole, with the hooks engaging with the slots to connect the lower and upper housings and create an internal cavity. The pressing shaft is housed within the cavity, with its top end passing through the through-hole. The spring is housed within the cavity and provides elastic support between the lower housing and the pressing shaft. This design allows for greater design flexibility in the upper housing, reduces manufacturing costs, and improves yield rates.

[0004] The existing keyboard key structure, when in use, causes the keys to frequently contact the inner walls of the lower and upper housings during the reciprocating lifting process. Otherwise, the keys are easily worn out and noise is generated. Therefore, it does not meet the current requirements, and a keyboard key with silent buffer is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a keyboard key with silent buffer, so as to solve the problem mentioned in the background art that when the existing keyboard key structure is used, the key will frequently contact the inner wall of the lower shell and the upper shell during the reciprocating lifting process, which will easily wear down the key and generate noise.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a keyboard key with silent buffer, comprising: a base, a top cover mounted on the top of the base, a key mounted at the middle position of the top cover, an inner groove formed inside the base, guide displacement frames mounted on both sides of the inner groove, an assembly groove formed at the middle position of the top cover, guide displacement grooves provided on both sides of the assembly groove and communicating with the guide displacement frames, displacement sliders mounted on both sides of the key and moving up and down within the guide displacement grooves and guide displacement frames, silent buffer components mounted at the top of the guide displacement grooves and the bottom of the guide displacement frames, the silent buffer components including a limiting pad mounted inside the guide displacement frames, and a rubber pad mounted on the bottom plate of the guide displacement frames.

[0007] Preferably, a rod is inserted inside the limiting pad, and end caps are installed at both ends of the rod.

[0008] Preferably, the side wall of the upper cover is provided with a plurality of insertion holes for inserting rods, and the insertion holes are arranged vertically at intervals.

[0009] Preferably, the inner walls of the guide displacement frame and the guide displacement groove at both ends are provided with side limiting grooves, and the front and rear ends of the displacement slider are provided with protrusions that are embedded in the side limiting grooves.

[0010] Preferably, end pads are installed at both the front and rear ends of the assembly groove.

[0011] Preferably, a first positioning post is installed at the middle position of the inner groove, a second positioning post is installed at the lower end of the button, and a spring is installed between the first positioning post and the second positioning post.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) In this utility model, by setting the guide displacement frame and guide displacement groove, the displacement slider at the button can slide up and down, and the pressing and resetting process of the button can be smoother. When the button is pressed, the displacement slider moves to the rubber pad, and the rubber pad prevents the displacement slider from directly contacting the base plate. When the button moves up to reset, the top of the displacement slider contacts the limiting pad. The above structure ensures that the button will not contact the housing during the lifting process, thereby improving the service life of the button and reducing the noise during the up and down displacement process.

[0014] (2) In this utility model, the limiting pad is restricted by the insertion of the plug rod. The user can insert it into the plug hole at different heights to adjust the height of the limiting pad, thereby limiting the height of the button when it is reset and adjusting the travel distance of the button. The end cap is fixed to the end of the plug rod by the screw rotation method, which restricts the plug rod from detaching. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-5 This utility model provides an embodiment of a keyboard key with silent buffer, comprising: a base 1, a top cover 2 mounted on the top of the base 1, a key 3 mounted in the middle of the top cover 2, an inner groove 101 inside the base 1, a first positioning post 102 mounted in the middle of the inner groove 101, a second positioning post 303 mounted at the lower end of the key 3, and a spring 103 mounted between the first positioning post 102 and the second positioning post 303. When the key 3 is pressed, the spring 103 is compressed at the key 3, causing it to descend. When the key 3 is released, the spring 103 extends, causing the key 3 to rise and return to its original position.

[0023] Guide displacement brackets 104 are installed on both sides inside the inner groove 101. An assembly groove 201 is opened in the middle of the upper cover 2. Guide displacement grooves 203 are provided on both sides of the assembly groove 201, and the guide displacement grooves 203 are connected to the guide displacement brackets 104. Displacement sliders 301 are installed on both sides of the button 3, and the displacement sliders 301 move up and down in the guide displacement grooves 203 and the guide displacement brackets 104. Silent buffers 4 are installed on the top of the guide displacement grooves 203 and the bottom of the guide displacement brackets 104. The silent buffers 4 also include a limiting pad 402, which is installed inside the guide displacement brackets 104. The silent buffers 4 include a rubber pad 401, which is installed on the bottom plate 106 at the bottom of the guide displacement brackets 104.

[0024] By setting the guide displacement bracket 104 and the guide displacement groove 203, the displacement slider 301 at the button 3 can slide up and down, making the pressing and resetting process of the button 3 smoother. When the button 3 is pressed, the displacement slider 301 moves to the rubber pad 401, and the rubber pad 401 prevents the displacement slider 301 from directly contacting the base plate 106. When the button 3 moves upward to reset, the top of the displacement slider 301 contacts the limiting pad 402. The above structure ensures that the button 3 will not contact the housing during the lifting process, thereby improving the service life of the button 3 and reducing noise during the up and down displacement process.

[0025] Furthermore, a rod 403 is inserted inside the limiting pad 402, and end caps 404 are installed at both ends of the rod 403. Several insertion holes 204 for the rod 403 to pass through are opened on the side wall of the upper cover 2, and the insertion holes 204 are arranged vertically at intervals. The limiting pad 402 is restricted by the insertion of the rod 403. The user can insert it into the insertion holes 204 at different heights to adjust the height of the limiting pad 402, thereby limiting the height of the button 3 when it is reset and rising, and thus adjusting the travel distance of the button 3. The end caps 404 are fixed to the end of the rod 403 by screw rotation, thus preventing the rod 403 from detaching.

[0026] Furthermore, end pads 202 are installed at both the front and rear ends of the assembly slot 201; the opening of the assembly slot 201 is sealed by the connection of the end pads 202, so that the inside of the assembly slot 201 will not be directly scraped during the lifting and lowering of the button 3, thereby achieving a further noise reduction effect.

[0027] Among them, the limiting pad 402 and the end pad 202 are made of materials such as rubber, polyurethane, and sponge.

[0028] Please see Figure 2 , Figure 4The inner walls of the guide displacement frame 104 and the guide displacement groove 203 at both ends are provided with side limiting grooves 105. The front and rear ends of the displacement slider 301 are provided with protrusions 302 embedded in the side limiting grooves 105. When sliding, the protrusions 302 are located in the side limiting grooves 105, making it difficult for them to detach from the guide displacement frame 104 and the guide displacement groove 203.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
