DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Embodiment 1:

[0027] In this embodiment, refer to Figure 1 - Figure 5 A silent push button switch is specifically implemented, including a shell and a shaft core 2 which can be lifted and lowered in the shell. The shell is composed of an upper cover 1-shell; 1A and a lower shell 1B. A spring 3 for cooperating with the shell is arranged at the lower end of the shaft core 2. Elastic parts 4 are embedded and installed on both sides of the shaft core 2. Contact parts 401 for abutting and cooperating with the shell are protruded at both ends of the elastic part 4.

[0028] Furthermore, a cavity is provided in the housing for the shaft core 2 to move up and down, and a plurality of guide structures 11A are provided on the inner wall of the cavity for slidingly cooperating with the shaft core 2. The guide structure 11A provided on the inner wall of the housing provides a clear path and stable support for the lifting and lowering movement of the shaft core 2. This not only ensures the stability and smoothness of the shaft core 2 during the movement, but also prolongs the service life of the key.

[0029] like Figure 3 As shown, the guide structure 11A is a vertically arranged arc edge. It not only matches the shaft core 2 and reduces friction resistance, but also enhances the stability and durability of the structure. Multiple guide structures 11A are evenly distributed in the four corners of the cavity, and the four ends of the outer periphery of the shaft core 2 cooperate with the guide structures 11A distributed in the four corners of the cavity, so that the shaft core 2 can slide up and down the linear track 11B under the limit of the guide structure 11A, and the guide structure 11A is integrally formed in the lower shell 1B, so that during the up and down movement of the shaft core 2, there is no need to transition to other tracks 11B, thereby significantly improving the stability of the up and down movement of the shaft core 2, avoiding shaking, looseness or deflection, and improving the user experience.

[0030] In this embodiment, the upper end of the shaft core 2 is provided with a cross key shaft 203 protruding from the outer shell. The cross key shaft 203 is composed of a vertical bone position and a horizontal bone position. In order to avoid the keycap installation direction being wrong, edges with increased thickness are provided on both sides of the horizontal bone position, and a slot for cooperating with the keycap is provided at one end of the vertical bone position to improve the stability of the keycap installation.

[0031] Furthermore, tracks 11B are provided on both sides of the cavity, and guide blocks 201 for slidingly cooperating with the tracks 11B are provided on both sides of the shaft core 2. A positioning groove 202 for accommodating the elastic member 4 is provided in the guide block 201, and the contact portion 401 protrudes from the positioning groove 202.

[0032] In this embodiment, the elastic member 4 is cylindrical, and one end of the positioning groove 202 is connected to the outside. During installation, the elastic member 4 can be directly inserted from the end of the positioning groove 202 that is open to the outside, thereby improving installation efficiency. The elastic member 4 and the positioning groove 202 are interference-fitted to ensure the stability of the installation of the elastic member 4.

[0033] Furthermore, one end of the elastic member 4 is provided with a locking position 402 for cooperating with the positioning groove 202 to prevent the elastic member 4 from falling out of the positioning groove 202 .

[0034] Furthermore, when the shaft core 2 is pressed to the bottom of the shell, a gap 6 is provided between the lower end surface of the shaft core 2 and the shell to prevent the shaft core 2 from colliding with the shell, thereby further reducing the occurrence of noise.

[0035] In this embodiment, a magnet 5 for triggering a Hall sensor on an external keyboard is installed at the lower end of the shaft core 2, that is, a common magnetic shaft key switch in the prior art.

[0036] The silent push button switch provided by the utility model has elastic members 4 on both sides of the shaft core 2, which effectively reduces the direct impact between the shaft core 2 and the shell during the up and down movement, thereby significantly reducing the noise during the use of the button, and is particularly suitable for public places or personal use where quietness needs to be maintained.

[0037] Embodiment 2:

[0038] like Figure 6-7 As shown, the difference between this embodiment and the first embodiment is that the elastic member 4 is in an I-shape, which not only ensures the strength and elasticity of the elastic member 4, but also facilitates the installation in cooperation with the positioning groove 202. At the same time, the contact parts 401 at both ends protrude from the positioning groove 202, which can more effectively abut against the housing and further reduce noise. The setting of the interference fit and the latch 402 ensures the stability and firmness of the elastic member 4 in the positioning groove 202, avoiding the situation of loosening or falling off during long-term use.

[0039] In summary, the silent push button switch provided by the utility model effectively solves the noise problem during the use of the buttons through clever design and reasonable structural layout, while ensuring the stability and service life of the buttons, bringing users a quieter and more comfortable use experience.
