Description

Technical Field

[0001] The utility model relates to the field of keyboards, in particular to a silent satellite shaft component for keyboards. Background Art

[0002] The satellite axis assembly in the keyboard, also known as the "press axis assembly", is a key structure to ensure the consistency of the feel of the large keys of the keyboard. The design principle of the satellite axis assembly is to add a mechanical axis at each end of the large key to ensure that the axis can be touched no matter where you press, thereby significantly improving the consistency of the keys. Compared with the balance bar, it plays a balancing and supporting role when pressing the large keys of the keyboard, thereby improving the stability of key operation, and therefore has been widely used.

[0003] The current satellite shaft assembly is provided with an elastic buckle on one side. When installed on the keyboard panel, the buckle fits too rigidly and is not easy to disassemble. In addition, when the satellite shaft assembly is in use, abnormal noise is easily generated between the balance bar and the shaft connector. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a silent satellite axis assembly for a keyboard to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a silent satellite axis assembly for a keyboard, comprising an axis seat and an axis core, the axis core is movably installed inside the axis seat, and a cavity is opened inside the axis core, a first elastic arm is fixed inside the cavity, and a second elastic arm is fixed inside the cavity, a balance rod is movably installed inside the cavity, an elastic rod is fixed to one side of the bottom of the axis seat, and a baffle is fixed to one side of the bottom of the axis seat, and a slot is opened on the outside of the baffle, and the axis seat and the axis core constitute a push axis assembly.

[0006] By adopting the above technical scheme, when the shaft core moves up and down in the shaft seat mounting groove, the first elastic arm and the second elastic arm are arranged to contact the balance rod, so as to avoid the balance rod being inserted into the shaft core and causing looseness due to excessive clearance inside the shaft core. At the same time, it can prevent the balance rod from hitting and making abnormal noise when the shaft core moves. When the pressing shaft assembly is installed on the keyboard panel, the first limiting part of the pressing rod and the second limiting part of the elastic rod cooperate with the card table to fix it on the keyboard panel. The pressing rod and the elastic rod have a certain elasticity. When the pressing rod is pushed, the elastic rod is squeezed to separate its first limiting part from the keyboard panel, so that the satellite shaft assembly can be easily disassembled and assembled.

[0007] The utility model is further configured that a mounting groove is provided at the bottom of the shaft seat, and a protrusion is fixed at the bottom of the shaft core.

[0008] By adopting the above technical solution, the shaft core can be easily installed through the opening of the installation groove, and the protrusion at the bottom of the shaft core can prevent the shaft core from detaching from the inner wall of the installation groove and being separated from the shaft seat.

[0009] The utility model is further configured that the two sides of the top of the shaft seat are respectively provided with a first clamping platform and a second clamping platform.

[0010] By adopting the above technical solution, the shaft seat and the keyboard panel can be installed by setting the first clamping platform and the second clamping platform.

[0011] The utility model is further configured that a cross shaft is fixed on the top of the shaft core.

[0012] By adopting the above technical solution, the cross axis can be arranged to facilitate the connection between the shaft core and the key cap.

[0013] The utility model is further configured that a pressing rod is fixed to a side of the shaft seat away from the elastic rod, and a first limiting portion is fixed to one side of the pressing rod.

[0014] By adopting the above technical solution, the set pressing rod can push the shaft seat to one side when installing, and then the shaft seat is clamped with the keyboard panel. The first limit part on one side of the pressing rod is clamped at the bottom of the keyboard panel, and the first clamping platform and the second clamping platform are located at the top of the keyboard panel, which can fix the shaft seat. The end of the pressing rod is higher than the first clamping platform, which can facilitate pushing the pressing rod, thereby facilitating disassembly of the shaft seat.

[0015] The utility model is further configured such that a through hole is provided inside the first card platform.

[0016] By adopting the above technical solution, the opening of the through hole can facilitate the movement of the pressing rod inside the through hole.

[0017] The utility model is further configured that a second limiting portion is fixed to one side of the elastic rod.

[0018] By adopting the above technical solution, the shaft seat can be easily limited so that when the shaft seat and the keyboard panel are installed, the bottom of the shaft seat will not be separated from the keyboard panel.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] The utility model is provided with a first elastic arm, a second elastic arm, an elastic rod and a balance rod. When the shaft core moves up and down in the shaft seat installation groove, it is prevented that the balance rod is inserted into the shaft core and the internal gap is too large to cause looseness. At the same time, it can prevent the balance rod from hitting and causing abnormal noise when the shaft core moves. When the satellite shaft assembly is installed on the keyboard panel, the first limiting part of the pressing rod and the second limiting part of the elastic rod are cooperated with the card table to be fixed to the keyboard panel. The pressing rod and the elastic rod have a certain elasticity. When the pressing rod is pushed, the elastic rod is squeezed to separate its first limiting part from the keyboard panel, so that the satellite shaft assembly can be easily disassembled and assembled.
