Abstract
Embodiments of the present disclosure disclose a rotary key force unloading mechanism, and an electronic device. The rotary key force unloading mechanism includes a key, a bourdon tube, and a cover cap; the cover cap is axially movable relative to the bourdon tube, and the cover cap and the bourdon tube are connected by an axially retractable elastic member; a stem portion of the key passes through the bourdon tube and the cover cap, so that the elastic member is compressed when the cover cap is pressed by a key cap of the key; and the stem portion of the key is provided with a limiting member for preventing separation, and when no axial force is applied on the key, no interaction forces exist between the limiting member and the bourdon tube.
Claims9
A rotary key force unloading mechanism comprising a key, a bourdon tube, and a cover cap;
- wherein the cover cap is axially movable relative to the bourdon tube, and the cover cap and the bourdon tube are connected by an axially retractable elastic member;
- wherein a stem portion of the key passes through the bourdon tube and the cover cap, so that the elastic member is compressed when the cover cap is pressed by a key cap of the key;
- and
- wherein the stem portion of the key is provided with a limiting member for preventing separation, and when no axial force is applied to the key, no interaction forces exist between the limiting member and the bourdon tube, and
- wherein one of the bourdon tube and the cover cap is provided with a buckle, and the other one is provided with a buckle groove that is engaged with the buckle, and the bourdon tube is coupled with the cover cap and is movable relatively with a limited displacement in an axial direction.
