Description

Technical Field

[0001] The utility model relates to the field of keyboard equipment, in particular to a satellite axis component. Background Art

[0002] Larger keys, such as the spacebar and the enter key, require the use of satellite shafts. Currently, when a key is pressed, the relative movement between the shaft core and the shaft seat produces even louder noise, often causing annoyance to the user and those around them. The inventor has been researching satellite shaft structures with a simple structure that effectively eliminates the collision noise generated by the relative movement of the inner and outer shafts. For example, Chinese utility model patent publication CN217822499U discloses a satellite shaft structure comprising one or more satellite shaft bodies, each comprising an outer shaft seat and an inner shaft. The outer shaft seat is provided with a first sliding groove with an upper opening for the inner shaft to slide up and down. The first sliding groove is provided with a soft rubber guide block, along which the inner shaft moves up and down within the first sliding groove. This utility model effectively reduces the noise generated when the inner shaft and outer shaft seat collide with each other. When the inner shaft moves up and down with the key, it strikes the soft rubber guide block of the outer shaft seat, rather than directly striking the hard rubber outer shaft seat. Because the soft rubber guide block is elastic, it can significantly reduce the impact noise generated when the inner shaft and outer shaft seat collide, thereby reducing noise.

[0003] In order to pursue a better silent effect, the inventor discovered that a better silent effect can be achieved by triggering the balance bar through a rocker mechanism. Utility Model Content

[0030] Furthermore, the shaft core 12 has a recess 121 for the rotatable member 13 to swing, and the fixed portion 131 of the rotatable member 13 is disposed in the recess 121. A pin hole 122 is provided on the shaft core 12 that passes through the recess 121.
