Embodiment 1

[0053] figure 1 A schematic diagram of the appearance of the keyboard structure 100 according to an embodiment of the present invention is shown. figure 2 It shows an exploded schematic diagram of a partial area A of the keyboard structure 100 according to an embodiment of the present invention. image 3 A cross-sectional schematic diagram of the keys 107 of the keyboard structure 100 according to an embodiment of the present invention is shown. Please refer to figure 1 , figure 2 and image 3 In one embodiment, the keyboard structure 100 includes a base 102, a frame 104, a thin film circuit board 106, and a plurality of keys 107. The base 102 is located at the bottom of the keyboard structure 100 and is used to carry the film circuit board 106 and the keys 107. The frame 104 is disposed on the base 102. More specifically, the frame 104 is fixed on the base 102 by means of screw locking or fastener locking.

[0054] The keys 107 are arranged on the base 102, and each key 107 re...

Embodiment 2

[0065] Image 6 It shows an exploded schematic diagram of a partial area of ​​the keyboard structure 100' according to an embodiment of the present invention. Figure 7 A schematic cross-sectional view of the keys 107 of the keyboard structure 100' according to an embodiment of the present invention is shown. Please refer to Image 6 and Figure 7 In this embodiment, the keyboard structure 100' includes a base 102, an outer frame portion 103, a frame 104, a film circuit board 106, and a plurality of keys 107. The detailed structure of the base 102, the frame 104, the thin film circuit board 106 and the button 107 has been described in detail in the above-mentioned embodiment, and will not be repeated here.

Abstract

The invention discloses a keyboard structure. The keyboard structure comprises a base, a frame and a plurality of keys, wherein the frame is arranged on the base, a plurality of keys are arranged on the base, the keys are separated by a frame region and are separated from each other, each key sequentially comprises a key cap, a limiting structure, an elastic piece and a film switch element from top to bottom, the elastic piece is arranged on the film switch element, the key cap is arranged on the elastic piece, the limiting structure is used for clamping the key cap to enable the key cap to move in a vertical direction relative to the film switch element, a flange is arranged on a peripheral surface of the key cap, and the flange is in contact with a bottom surface of the frame in the vertical direction. The keyboard structure is advantaged in that dust or moisture is not easy to permeate into the keyboard structure, so waterproof and dustproof performances of the keyboard structure are improved.

Description

Technical field [0001] The invention relates to a keyboard structure, and in particular to a waterproof and dustproof keyboard structure. Background technique [0002] The existing keyboard includes a key cap, a scissor foot structure, an elastic piece and a film circuit board. The elastic member is arranged under the key cap to provide an elastic restoring force of the key cap. The scissor foot structure is used to support the key cap so that the elastic member can be pressed when the key cap is pressed, so as to transmit the downward pressure to the film circuit board and touch the switch element on the film circuit board. [0003] However, dust can easily enter the keyboard from the gap between the two keycaps. At the same time, when the keyboard is not covered by a waterproof sheath, moisture can easily enter the keyboard from the gap between the two keycaps, which needs further improvement. Summary of the invention [0004] The purpose of the present invention is to provide a...
