Double-stroke key structure

Abstract

The utility model discloses a double-stroke key structure which comprises a first key, a second key and a key cap, silica gel pads are arranged between the key cap and the first key and between the key cap and the second key, and a first abutting end and a second abutting end corresponding to the first key and the second key are arranged at the bottom of each silica gel pad. The length of the first abutting end is the same as that of the second abutting end, and the first key is slightly higher than the second key. Compared with the prior art, the double-stroke button has the advantages that the elasticity of the silica gel pad is utilized, and the height difference between the first button and the second button or the length difference between the first abutting end and the second abutting end is combined, so that a single button can realize a double-stroke function, and additional functions of the button can be expanded conveniently.

Description

Technical Field

[0001] The utility model relates to a key structure, in particular to a double-stroke key structure. Background Art

[0002] Most existing keys are single-stroke keys, each with a single function. Although there are a few dual-stroke keys, such as the utility model patent in Chinese Patent Publication No. CN 106888294 A, entitled "A Portable Smartphone," discloses an integrated dual-stroke key structure comprising a keycap, a key buffer, a key holder, a key bottom support, a key connecting plate, an upper pot carrier, and a lower pot carrier. The upper pot carrier is disposed between the key connecting plate and the key buffer, for communicating circuit signals, and the lower pot carrier is disposed between the key connecting plate and the key bottom support, for communicating circuit signals. This design distinguishes the different strokes of the integrated dual-stroke key by disposing upper and lower pot carriers of different arc radii and the same thickness on the front and back sides of the key connecting plate. However, this structural design requires extremely high precision; otherwise, when pressing downward, it is easy to accidentally press the lower pot carrier, meaning that the upper pot carrier may be pressed instead of the upper one. Therefore, developing a dual-stroke key structure has become a pressing issue for those skilled in the art. Utility Model Content

[0003] The utility model provides a double-stroke key structure in order to solve the above-mentioned deficiencies.

[0004] The above-mentioned purpose of the present utility model is achieved through the following technical solutions: a double-stroke key structure, including a first key, a second key and a keycap, a silicone pad is provided between the keycap and the first key and the second key, and the bottom of the silicone pad is provided with a first contact end and a second contact end corresponding to the first key and the second key, the lengths of the first contact end and the second contact end are the same, and the first key is slightly higher than the second key.

[0005] The above-mentioned purpose of the present utility model is achieved through the following another technical solution: a double-stroke key structure, including a first key, a second key and a keycap, a silicone pad is provided between the keycap and the first key and the second key, and a first contact end and a second contact end corresponding to the first key and the second key are provided at the bottom of the silicone pad, the first key and the second key have the same height, and the first contact end is slightly longer than the second contact end.

[0006] The advantages of the present invention over the prior art are: the present invention utilizes the elasticity of the silicone pad and combines the height difference between the first button and the second button or the length difference between the first contact end and the second contact end to enable a single button to achieve a dual-stroke function, thereby facilitating the expansion of additional functions of the button.

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] Example 1: Figure 1 、 Figure 2 、 Figure 3 and Figure 7 As shown, a double-stroke key structure includes a first key 1, a second key 2 and a keycap 3. The first key 1 and the second key 2 are arranged on a PCB board 7. A silicone pad 4 is provided between the keycap 3 and the first key 1 and the second key 2. The bottom of the silicone pad 4 is provided with a first contact end 5 and a second contact end 6 corresponding to the first key 1 and the second key 2. The lengths of the first contact end 5 and the second contact end 6 are the same. The first key 1 is slightly higher than the second key 2, generally 1-3 mm higher.

[0016] Example 2: Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, a double-stroke key structure includes a first key 1, a second key 2 and a keycap 3. The first key 1 and the second key 2 are arranged on a PCB board 7. A silicone pad 4 is provided between the keycap 3 and the first key 1 and the second key 2. The bottom of the silicone pad 4 is provided with a first contact end 5 and a second contact end 6 corresponding to the first key 1 and the second key 2. The first key 1 and the second key 2 have the same height. The first contact end 5 is slightly longer than the second contact end 6, generally 1-3 mm longer.

[0017] The working principle of this utility model is as follows: when the keycap 3 is pressed, the keycap 3 presses down the silicone pad 4. The first contact end 5 of the silicone pad 4 first contacts and presses down the first button 1. If the keycap 3 is pressed, the first button 1 is pressed down. If the keycap 3 is pressed down, the first contact end 5 is further compressed, and then the second contact end 6 contacts and presses down the second button 2, thereby achieving the effect of pressing the first button 1 and the second button 2 at the same time. In actual application, triggering the first button 1 gives it one function, while triggering the first button 1 and the second button 2 gives them another function.

[0018] The first button 1 and the second button 2 in embodiments 1 and 2 can be the same type of buttons or different types of buttons. The buttons can be light touch buttons, conductive adhesive buttons, micro switches, etc.

[0019] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
