Detailed Description

The invention provides a mechanical damper, which comprises: eccentric wheel 1, motion axle 2, track seat 3.

The track seat 3 is fixedly connected with a product shell provided with a mechanical damper;

the moving shaft 2 is fixedly connected or hinged with a product executing mechanism provided with a mechanical damper;

the eccentric wheel 1 is hinged with the moving shaft 2 and is placed in an eccentric wheel track 4 of the track seat 3.

During operation, the moving shaft 2 moves to drive the eccentric wheel 1 to move along the eccentric wheel track 4 (the track can be set according to actual requirements). When the eccentric 1 moves along the eccentric track 4. The reaction force of the eccentric wheel track 4 to the motion of the eccentric wheel 1, the force required for the eccentric wheel 1 to rotate and the friction force of the eccentric wheel 1 in the eccentric wheel track 4 form a damping of the motion shaft 2.
