Abstract
A variable damping assembly includes a base, a supporting member, a damping member, and an elastic member. The supporting member is positioned on the base. The damping member is rotatably coupled to the supporting member and presses against the housing. The elastic member includes a first end and a second end opposite to the first end. The first end of the elastic member is coupled to the supporting member and the second end of the elastic member is coupled to the housing. The elastic member provides an elastic force and the damping member provides a damping force changed as the elastic force changes.
Claims18
A variable damping assembly in a housing of a device, the variable damping assembly comprising:
- a base;
- a supporting member positioned on the base;
- a damping member, the damping member rotatably coupled to the supporting member and pressed against the housing;
- and
- an elastic member comprising a first end and a second end opposite to the first end, the first end of the elastic member coupled to the supporting member, and the second end of the elastic member coupled to the housing;
- wherein the elastic member provides an elastic force and the damping member provides a damping force changed as the elastic force changes.
An air filtering device comprising:
- a main body;
- a housing sleeved on the main body;
- and
- at least one variable damping assembly positioned inside the housing and comprising:
- a base;
- a supporting member positioned on the base;
- a damping member, the damping member rotatably coupled to the supporting member and pressed against the housing;
- and
- an elastic member comprising a first end and a second end opposite to the first end, the first end of the elastic member coupled to the supporting member, and the second end of the elastic member coupled to the housing;
- wherein the elastic member provides an elastic force and the damping member provides a damping force changed as the elastic force changes, the elastic force and the damping force cooperatively control the housing to lift up relative to the main body.
