Description

Balancing rod-based keyboard satellite shaft capable of being assembled automatically in adaptive mode Technical Field The utility model relates to the technical field of keyboard accessories, in particular to a keyboard satellite shaft which is based on a balance rod and can be assembled in an adaptive and automatic mode. Background The satellite shaft is an auxiliary structure for stabilizing a large key (such as a space key, a carriage return key and the like) in the mechanical keyboard, and the auxiliary shaft and the linkage steel wire system which are symmetrically distributed ensure that the large key is uniformly stressed when pressed, so that one-side jamming or shaking is avoided. The method is widely applied to the fields of large key position design and customized keyboards of mechanical keyboards, and is particularly suitable for office or learning scenes needing mute environments. The key advantages of the device include balanced knocking force, reduced friction noise, prolonged service life, and consistency with hand feeling of a large key position through adjustment (such as lubrication and noise reduction treatment), so that overall input experience is improved. The applicant filed before (CN 202123252409.7, entitled "key connection structure based on balance bar") discloses a satellite shaft solution consisting of a shaft core 10, a shaft seat 20 and a balance bar 30, as shown in fig. 1 and 2 (see the drawings of the specification). In the scheme, the balance bar 30 consists of a rotating section 33, a transmission section 32 and a sliding section 31, wherein the installation is completed through the following complex steps of firstly placing the axle center 10 in the axle seat 20 through the bottom of the axle seat 20, secondly arranging the balance bar 30 on the whole side, enabling the sliding section 31 to pass through the opening 23 of the axle seat 20, manually adjusting the angle of the balance bar 30, clamping the sliding section 31 into the installation groove 11 of the axle center 10, thirdly clamping the rotating section 33 into the clamping groove 21 of the axle seat 20, and fourthly completing the assembly. However, in actual production, it is found that the above-mentioned installation procedure, especially the second step, needs to rely on multiple multi-angle manual adjustment, and the operation fault tolerance is low, resulting in low assembly efficiency. The problem severely limits the application scene of the product, which can only be popularized on a small scale for DIY lovers and cannot adapt to the requirement of mechanized mass production. Therefore, the applicant optimizes and improves the satellite shaft structure, and through redesign of key component forms and assembly paths, the installation process is obviously simplified, so that the satellite shaft structure is compatible with an automatic production line, and further the satellite shaft structure is expanded to the consumer-grade keyboard market. Disclosure of utility model In order to achieve the purpose of the utility model, the utility model provides a keyboard satellite shaft which is based on a balance rod and can be assembled automatically in an adapting way, and the keyboard satellite shaft comprises two satellite shaft modules which are arranged in a mirror symmetry way, wherein each module consists of a shaft seat and a shaft center capable of vertically moving; the shaft seat is provided with a vertical channel for accommodating the shaft center, the bottom of the shaft center is provided with a mounting groove in the horizontal direction, and the outer wall of the shaft seat is provided with a clamping groove; The balance rod comprises a rotating section and sliding sections at two ends, wherein the rotating section is connected with the sliding sections through a transmission section, and the rotating section is clamped in clamping grooves of the two shaft seats; The side of axle bed has seted up the installing port, the extending direction of installing port with the horizontal direction of mounting groove aligns, the slip section passes through the installing port direct insertion corresponds in the mounting groove of axle center, just the slip section can be along with the vertical motion of axle center horizontal smooth motion in the mounting groove, realizes the synchronous linkage of both ends axle center.
