Problems solved by technology

However, the cost of silicone rubber is relatively high, and the corners of the silicone dome 202 manufactured by the process of one mold with multiple holes or the corners of the whole piece are different from the center material, resulting in a deviation in hand feeling. In addition, the structure of the silicone dome has limitations on the key travel and poor hand feeling

Embodiment Construction

[0022] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0023] figure 2 A schematic diagram of a three-dimensional structure of a keyboard key provided by an embodiment of the present invention; image 3 for figure 2 A schematic diagram of the explosion structure of the keyboard keys; Figure 4 for figure 2 A schematic cross-sectional structure diagram along the A-A' direction when the keyboard keys are in a free state. Such as Figure 2 to Figure 4 As shown, the keyboard key 100 includes: a keycap 1 , a base 2 , a thin film circuit board 3 , an elastic element 4 and a contact piece 5 . The keycap 1 has a first position, a second position, and a third position relative to the base 2, and in the first position, the keycap 1 and the base 2 have a first distance, and in the second position, the keycap 1 and the base 2...

Abstract

The invention provides a keyboard key which can provide good hand feeling. The keyboard key comprises a key cap, a base, a thin-film circuit board, an elastic component and a contact piece, and is characterized in that one end of the elastic component is arranged on the base, and the other end of the elastic component is suspended in the air; the contact piece is arranged on the elastic component; when the keyboard key stays at a free state, the key cap is located at a first position, and a first distance is reserved between the contact piece and the thin-film circuit board; when the key cap moves towards the base from the first position along a first direction, the keycap is pressed against the elastic component until the key cap moves to a second position, and the contact piece is pressed against the thin-film circuit board; and when the key cap continues to move towards the base along the first direction from the second position, the key cap continues to be pressed against the elastic component and further enables the contact piece to have elastic deformation in the first direction until the key cap moves to a third position, and the contact piece continues to be pressed against the thin-film circuit board in the process of moving from the second position to the third position of the key cap.

Description

technical field [0001] The invention relates to the technical field of keyboards, in particular to a keyboard key comprising two spring parts and a keyboard using the keyboard key. Background technique [0002] Along with the rising of people to the requirement of daily necessities, people are also more and more higher to the requirement of computer keyboard commonly used when particularly operating computer. [0003] figure 1 It is a sectional view of a keyboard key in the prior art when it is in a free state, such as figure 1 As shown, the keyboard key 200 includes a keycap 201, a rubber dome 202, a film circuit board 203 and a base 204, wherein the rubber dome 202 is used to support the keycap and provide elastic recovery when the user presses the keycap 201 force. The rubber dome 202 is usually made of silicon rubber (Silicon Rubber) injection molded as a whole piece or the silicon rubber is pasted on the plastic through a multi-cavity process. However, the cost of s...
