Waterproof button structure

Abstract

A waterproof key structure comprises a shell, a keycap, a plurality of waterproof components, and a fastener. The shell has a first surface and a second surface. The shell is provided with a pair of perforations and a groove. The groove is arranged in the second surface and formed between the pair of perforations. The key cap can move along the normal direction of the first surface of the shell. The keycap is provided with a pair of keycap shafts, and the keycap shafts are respectively inserted into the perforations. The waterproof components are arranged between the keycap shafts and the perforations. The fastener is assembled on the pair of keycap shafts, and corresponds to the second surface. The fastener has a bent part which is arranged convexly towards the groove and has a bulge. When the keycap is pressed, the bulge presses against a push switch. Thus, the size of the key structure is reduced, and products can be lighter and thinner.

Description

【Technical field】 [0001] The invention relates to a key structure, especially a waterproof key structure with a smaller size. 【Background technique】 [0002] With the advancement of science and technology, the development trend of electronic products is mainly moving towards the direction of multi-function, fast computing speed and small size. With the introduction of these high-tech electronic products, the life style of modern people has also changed, and the convenience brought by these high-tech products can be seen no matter in terms of study, work or leisure. Currently, smart phones are one of the most popular high-tech electronic products. In addition to smart phones, related companies have launched so-called smart watches and other wearable devices. [0003] Since the smart watch must be smaller than the smart phone, the battery volume of the smart watch must also be smaller, but such a shortcoming will not be able to be used for a long time due to insufficient bat...

AI Technical Summary

Problems solved by technology

However if figure 1 As shown in the traditional mechanical button structure, the external force from the user’s pressing makes the keycap 12 bear the force in one direction, which is not only easy to shake and unable to bear the force evenly, but also easy to wear the waterproof ring 22 arranged on the single shaft 14, and then make water infiltrate

In addition, such mechanical buttons do not meet the needs of future shrinking electronic devices, especially buttons for wearable devices

[0004] In view of this, how to solve the problem that the traditional mechanical button structure causes the wear and tear of the waterproof element and the problem that the size cannot be reduced is an important issue that those engaged in this industry are eager to study and improve.
