Description

Technical Field

[0001] The utility model belongs to the field of electronic equipment, and in particular relates to a key structure and electronic equipment. Background Art

[0002] At present, with the increasing application of three-proof products in outdoor and special industries, the requirements for the waterproof performance of products are getting higher and higher. There are two main solutions for the waterproofing of buttons.

[0003] The first is to set the button and the shell as a whole. The advantage of this solution is high waterproof performance, but the disadvantage is that the button cannot be replaced individually. Once cracks appear on the button, the repair cost is high.

[0004] The second is to set a waterproof structure at the key. This solution allows the keys to be replaced individually, but the waterproof performance is lower than the first solution. The traditional waterproof structure is to press the waterproof silicone downward or sideways to make it elastically deform and fill the gaps in the structure, thereby achieving the purpose of waterproofing. In order to better achieve waterproofing, waterproof glue will be applied to the key to improve the waterproof performance of the key. However, the addition of the glue application process will increase material costs and labor costs. Utility Model Content
