Problems solved by technology

[0004] However, due to the scissor mechanism design adopted by the supporting device 16, it requires a larger height space, thereby further increasing the overall height of the key 1, which is not conducive to the application of thinning the keyboard.
In addition, the elastic member 18 is usually made of rubber, and the rubber will be fatigued under long-term use, thereby shortening the service life of the button 1

Embodiment Construction

[0023] see Figure 2 to Figure 5 , figure 2 It is a three-dimensional schematic diagram of the button 3 proposed according to the first embodiment of the present invention, image 3 for figure 2 The schematic diagram of the explosion of button 3, Figure 4 for figure 2 A schematic cross-sectional view of the button 3 along the section line A-A', Figure 5 for Figure 4 A schematic cross-sectional view of the top cover 32 when it is pressed. Such as Figure 2 to Figure 5 As shown, the button 3 includes a bottom plate 30 , a top cover 32 , a supporting device 34 and a circuit board 36 . In practical applications, the circuit board 36 is disposed on the base plate 30 and may be a thin film circuit board, but not limited thereto.

[0024] The supporting device 34 is disposed between the bottom plate 30 and the top cover 32 , and is rotatably connected to the top cover 32 and the bottom plate 30 respectively. In this embodiment, the support device 34 may include a first...

Abstract

The invention relates to a press key which comprises a bottom plate, a top cover, a support device and a springback device, wherein the bottom plate is provided with a first magnetic area. The top cover is provided with a second magnetic area, and the position of the first magnetic area corresponds to that of the second magnetic area. The support device is arranged between the bottom plate and the top cover, and the top cover moves between a non-pressed position and a pressed position, opposite to the support device. The springback device is arranged between the bottom plate and the top cover. When the top cover is pressed by external force so as to cause the first magnetic area approaching to the second magnetic area, magnetic attraction force between the second magnetic area and the first magnetic area enables the top cover to be quickly moved to the pressed position. When the external force is released, the springback device enables the top cover to be returned to the non-pressed position. Through the design of the first magnetic area and the second magnetic area on the top cover and the bottom plate, good key press operation feeling is provided when a user presses and releases the top cover.

Description

technical field [0001] The present invention relates to a button, in particular to a button which utilizes the magnetic attraction force of the magnetic regions on the top cover and the bottom plate to drive the top cover to accelerate to the pressed position, and uses a rebound device to drive the top cover back to the unpressed position. Background technique [0002] As far as current personal computer usage habits are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Not only that, but all consumer electronic products in daily life or large-scale processing equipment used in the industry need to be equipped with a key structure as an input device to operate the above-mentioned electronic products and processing equipment. [0003] see figure 1 , which is a schematic cross-sectional view of the key 1 in the prior art. Such as figure 1 As shown, the button 1 includes a bottom plate 10 , a keycap 12 , a circuit...
