Abstract

The invention discloses a waterproof key structure and an electronic device. The waterproof key structure comprises a closed shell, a conducting coil, an inductor and a dial wheel. The closed shell is provided with a groove, the conducting coil is located in the closed shell and wound around the groove, the inductor is located in the closed shell and electrically connected with the two ends of the conducting coil, and the dial wheel is magnetic, arranged outside the closed shell and located in the groove. When the dial wheel moves clockwise or anticlockwise, the conducting coil cuts magnetic induction lines generated by the dial wheel, and currents are generated to trigger the inductor to achieve the key function. The electronic device comprises the waterproof key structure, the problem that a dial wheel structure is not waterproof is solved, and the closed waterproof effect is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of waterproof button structure design, and in particular, to a waterproof button structure and electronic equipment. Background technique [0002] Waterproof electronic devices are more and more popular with consumers because of their unique performance, and there are more and more waterproof electronic devices on the market. [0003] The button of the electronic equipment on the market at present adopts the form of the dial, and the traditional dial generally provides a through hole on the housing of the electronic equipment, and the dial is installed in the through hole, and the dial is connected with the circuit board in the housing. Connect to realize the button function. Since the casing is not sealed, the dial is connected to the circuit board in the casing through the through hole, so it is not waterproof. Contents of the invention [0004] The invention provides a waterpr...
