Title:
WRIST-WORN ELECTRONIC DEVICE AND WATERPROOF STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2021/082260
Kind Code:
A1
Abstract:
Some embodiments of the present application disclose a wrist-worn electronic device and a waterproof structure. The waterproof structure comprises a shell which is provided with an air hole extending therethrough, a waterproof membrane is provided in a mounting cavity in the shell which abuts the inner side opening of the air hole, and the air hole is internally provided with a ball having waterproof performance and a constraint structure which constrains the ball in a preset range in the air hole; the preset range has a space allowing the ball to freely move; in a gas environment, there is a gap between the ball and a boundary face of the preset range, so as to allow the communication between the inner side opening and the outer side opening of the air hole; and the ball can press against the constraint structure under the pushing of liquid entering from the outer side opening and seal the inner side opening. When liquid enters the air hole, the ball is subjected to an impact and thus moves towards the inner side opening and presses against the constraint structure, thereby sealing the inner side opening. With the increase of water pressure, the ball can press against the constraint structure more tightly, avoiding the waterproof membrane directly bearing a large water pressure, providing strong waterproof capability.
