Description

Technical Field

[0001] The utility model relates to the technical field of scissor-foot keyboards, and more particularly to a key structure of a scissor-foot keyboard. Background Art

[0002] The keyboard is the most commonly used and primary input device. It allows users to enter English letters, Chinese characters, numbers, punctuation marks, and other symbols into a computer, thereby issuing commands and inputting data. Some keyboards also feature various shortcut keys. Scissor-foot keyboards feature an X-shaped bracket beneath the keycaps, which, together with the silicone cup beneath, provides support for the keycaps. Existing scissor-foot keyboards only have a single elastic projection to reset the key after pressing it. After prolonged use, this projection ages, causing the key to rebound poorly when pressed, reducing the user's tactile experience. Therefore, we have proposed a new scissor-foot keyboard key structure. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a key structure of a scissor-foot keyboard to solve the problem raised in the above background technology that the elastic protrusions will age to a certain extent after long-term use, and the keys are prone to poor rebound effect when pressed.

[0004] To achieve the above object, the present invention provides the following technical solution: a key structure of a scissor-foot keyboard, comprising a key base and a key cap, wherein the key cap is arranged directly above the key base, an elastic protrusion is fixed above the key base, and a supporting scissor mechanism is provided between both sides of the key cap and the key base;

[0005] The two lever of the upper right corner is installed in the range of 1 to 25. The two lever of the lower right corner has the upper and lower ends of which are located adjacent the bottom of the gear train and the lower ends of the gear train are connected along the vertical cam path to form a loop of motion.

[0006] As a preferred technical solution of the present invention, mounting holes are provided at the four corners of the button base.

[0007] As an optimal technical solution of the present invention, the insertion mechanism includes a slot and an insertion plate, the slot is opened on one side of the lower slide plate and the upper slide plate, the insertion plate is fixed on one side of the upper mounting plate and the lower mounting plate, and the insertion plate is inserted in the slot, and arc grooves are opened on both side walls of the slot, rubber protrusions are fixed on both sides of the insertion plate, and the rubber protrusions are inserted in the arc grooves.

[0008] As a preferred technical solution of the present invention, a rubber pad is fixed to the side wall of the slot.

[0009] As an optimal technical solution of the present invention, the rebound mechanism includes an upper plate and a lower plate, the upper plate is respectively fixed on one side above the first rotating rod and the second rotating rod, the lower plate is respectively fixed on one side below the first rotating rod and the second rotating rod, and a spring is fixed between the upper plate and the lower plate.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] The utility model can support the key cap through the supporting scissors mechanism between the two sides of the key cap and the key base. When the key cap is pressed, the elastic protrusion will be deformed. When the key cap is released, the elastic protrusion will drive the key cap to reset. The key cap can be assisted to rebound by the rebound mechanism between the first rotating rod and the second rotating rod, thereby effectively reducing the impact of aging of the elastic protrusion.
