Problems solved by technology

[0002] The keyboard key film is a product between the key cap and the key switch base to protect the key switch base. During the use of the key, dust will easily enter the key switch base and adhere to the control rod under the key cap. Or on the base of the key switch, so the keyboard key film is an indispensable accessory to protect against dust from entering, but the dust-proof effect of the key keyboard film is still not ideal, and some dust particles will still enter it, which will be serious over time Affect the user experience

Embodiment 1

[0022] Such as Figure 1 to Figure 3 As shown, a keyboard key membrane described in this embodiment is used to wrap the key membrane body 1 of the key button, and the top of the key membrane body 1 is provided with a through hole 3 for the control rod of the keycap to pass through. The edge of the through hole 3 extends to the center of the through hole 3 with a first tongue edge 41; through the first tongue edge 41 provided, its free end will abut against the outer wall of the control rod under the keycap to prevent dust Further entering into the key membrane membrane body 1, effectively solving the problem of entering dust.

[0023] In the keyboard key membrane described in this embodiment, the key membrane body 1 is made of silica gel material; the silica gel material is softer and more durable, less prone to damage, and can reduce frustration and increase experience in use, effectively improving the performance of the present invention. practicality.

[0024] In the keyb...

Embodiment 2

[0030] Such as image 3 , a kind of keyboard button membrane described in the present embodiment differs from Embodiment 1 in that: specific dimensions are set, the angle a between the first tongue edge 41 and the horizontal plane is between 100° and 110°; the second The angle b between the tongue edge 42 and the horizontal plane is between -100° and -110°; the thicknesses of the first tongue edge 41, the second tongue edge 42, and the third tongue edge 43 are all between 0.05-0.2mm The distance between the first tongue edge 41 and the second tongue edge 42, the second tongue edge 42 and the third tongue edge 43 is between 0.1-0.25mm; the first tongue edge 41, the second tongue edge The lengths of the edge 42 and the third tongue edge 43 are between 0.1-0.25mm.

Abstract

The invention discloses a keyboard key film. The keyboard key film is used as a key film body for wrapping a key button of a key, wherein the top end of the key film body is provided with a through hole which enables a control bar of a key cap to pass through; the edge of the through hole stretches a first tongue edge toward the center of the through hole; and by means of the first tongue edge, a free end of the first tongue abuts against the outer wall of the control bar of the key cap to prevent the dust from entering the key film body so that the problem of dust entry can be effectively solved.

Description

technical field [0001] The invention relates to a keyboard accessory, in particular to a keyboard key membrane. Background technique [0002] The keyboard key film is a product between the key cap and the key switch base to protect the key switch base. During the use of the key, dust will easily enter the key switch base and adhere to the control rod under the key cap. Or on the base of the key switch, so the keyboard key film is an indispensable accessory to protect against dust from entering, but the dust-proof effect of the key keyboard film is still not ideal, and some dust particles will still enter it, which will be serious over time affect the user experience. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings, and provide a keyboard key membrane with excellent dustproof effect. [0004] In order to achieve the above object, the specific scheme of the present invention is as follows: a keyboard ke...
