In order to maintain the rebounding speed of the switch, the strength of the built-in spring is relatively high, and users need to use a relatively large force to complete the pressing during use. The working intensity of the fingers is relatively large after long-term use, which is not convenient for use. Content of the Utility Model

[0026] The present utility model provides a technical solution:
[0027] Embodiment 1
[0028] Combined with Figures 1 to 4 , a hot-swappable key module for a mechanical keyboard, comprising a shaft body housing 3, a convex edge 31 fixedly connected to the outside of the shaft body housing 3, a touch mechanism 1 arranged inside the shaft body housing 3, and a connection mechanism 2 arranged inside the bottom of the shaft body housing 3.
[0029] The touch mechanism 1 includes a resilience component 11, a connection component 12, and a buffer component 13. The resilience component 11 is arranged at the inner bottom of the shaft body housing 3, the connection component 12 is arranged on the top of the resilience component 11, and the buffer component 13 is arranged at the bottom of the connection component 12.
[0030] The resilience component 11 includes a fixed box 1101 fixedly connected to the inner bottom of the shaft body housing 3. A sliding piece 1102 is slidably connected inside the fixed box 1101. The bottom of the sliding piece 1102 is fixedly connected to a return spring 1103, and the return spring 1103 is fixedly connected to the inner bottom of the shaft body housing 3. The connection component 12 includes a buffer spring 1201 fixedly connected to the top of the fixed box 1101. The top of the buffer spring 1201 is fixedly connected to a sliding shell 1202, and the sliding shell 1202 is slidably connected inside the shaft body housing 3. The top of the sliding shell 1202 is fixedly connected to a connection convex 1203, and the connection convex 1203 is slidably connected inside the top of the shaft body housing 3. The buffer component 13 includes a buffer sleeve 1301 fixedly connected to the top of the sliding piece 1102. The buffer sleeve 1301 is slidably connected inside the top of the fixed box 1101. A rubber slider 1302 is slidably connected inside the buffer sleeve 1301. The top of the rubber slider 1302 is fixedly connected to a first sliding rod 1303, and the first sliding rod 1303 is fixedly connected to the inner top of the sliding shell 1202. The first sliding rod 1303 is slidably connected inside the top of the buffer sleeve 1301.
[0031] Furthermore: The number of the reset springs 1103 is four, and the restoring force generated by them on the sliding piece 1102 is greater than the restoring force generated by the buffer spring 1201 on the sliding shell 1202. When the shaft body module is in use, the connecting convex 1203 is stressed downward and first drives the sliding shell 1202 to move downward, and then drives the sliding piece 1102 to move downward through the buffer assembly 13, so that the pressing process of the shaft body during use is divided into two-stage force application processes. The reset spring 1103 enables the shaft body to have a sufficiently sensitive and timely rebound breakpoint during use, while the buffer spring 1201 enables the shaft body to have a partial energy storage distance during the pressing process, reducing the pressing force required at the initial stage of the shaft body during use and facilitating use.
[0032] Embodiment 2
[0033] Refer to Figure 2 、 Figure 3 and Figure 5 On the basis of Embodiment 1, it is further obtained that the connecting mechanism 2 includes a power connection component 21, a reset component 22 and a point contact component 23. The connecting mechanism 2 is arranged inside the bottom of the shaft body housing 3. The reset component 22 is arranged on the top of the power connection component 21, and the point contact component 23 is arranged on the top of the reset component 22.
[0034] The power connection component 21 includes a power connection copper plate 2101, which is fixedly connected inside the bottom of the shaft body housing 3. A power connection block 2102 is fixedly connected to the top of the power connection copper plate 2101, and the power connection block 2102 is clamped inside the bottom of the shaft body housing 3. A power connection convex 2103 is fixedly connected to the bottom of the power connection copper plate 2101. The reset component 22 includes a fixed cylinder 2201, which is fixedly connected to the top of the power connection block 2102. A power connection slider 2202 is slidably connected inside the fixed cylinder 2201. A compression spring 2203 is fixedly connected to the bottom of the power connection slider 2202, and the compression spring 2203 is fixedly connected to the inner bottom of the fixed cylinder 2201. The point contact component 23 includes a second sliding rod 2301, which is fixedly connected to the top of the power connection slider 2202. The second sliding rod 2301 is slidably connected inside the top of the fixed cylinder 2201, and a point contact piece 2302 is fixedly connected to the top of the second sliding rod 2301.
[0035] Furthermore: The internal components of the power connection component 21, the reset component 22 and the point contact component 23 are all copper-based power connection materials. The sliding piece 1102 moves downward to contact the point contact piece 2302 to complete the point contact work of the shaft body. The presence of the power connection slider 2202 and the compression spring 2203 enables the point contact piece 2302 to slide downward by a certain distance under force during the process of the sliding piece 1102 moving downward to contact the point contact piece 2302, so that the point contact piece 2302 will not be deformed due to long-term use, increasing the service life of the shaft body.
[0036] During actual operation, when this device is in use, when the shaft body is in use, pressing down the keycap drives the connecting convex 1203 to move downward. The downward movement of the connecting convex 1203 drives the first slide bar 1303 and the rubber slider 1302 to move downward until the rubber slider 1302 slides downward and contacts the top of the sliding piece 1102. Then, a force is applied to the sliding piece 1102 to drive the sliding piece 1102 to move downward. The downward movement of the sliding piece 1102 contacts the top of the touch contact piece 2302 to complete the touch. After that, the user's finger leaves the keycap. At this time, the return spring 1103 drives the sliding piece 1102 to move upward and disconnect from the touch contact piece 2302. At this time, the use of the shaft body is completed.
[0037] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
