Abstract

The invention discloses a damping hinge which comprises a rotating shaft (1), a rotating arm (2) and a fixed arm (3). The rotating shaft (1) is connected with the end of the rotating arm (2) and the end of the fixed arm (3), the rotating arm (2) and the fixed arm (3) can rotate relatively by taking the rotating shaft (1) as a center, an inner magnet mounting seat (5) is mounted on the rotating shaft (1), an inner magnet (6) is fixedly mounted on the inner magnet mounting seat (5), a ratchet wheel (5-2) is arranged on one side, close to the rotating arm (2), of the inner magnet mounting seat (5), a pawl (4-4) matched with the ratchet wheel (5-2) is fixedly connected on the rotating arm (2), an outer magnet (7) is fixedly connected on the fixed arm (3), each of the inner magnet (6) and the outer magnet (7) is in the shape of a circular arc formed by bonding two poles of multiple magnets in a staggered arrangement manner, and magnetic force between the inner magnet (6) and the outer magnet (7) is larger than resistance generated when the ratchet wheel (5-2) and the pawl (4-4) rotate forwards. The damping hinge is long in service life and small in structural size.

Description

technical field [0001] The invention relates to the field of mechanical connections, in particular to a damping hinge. Background technique [0002] A hinge is a mechanical device used to connect two solids and allow them to rotate relative to each other, and the use of hinges is very common in various rotating structures. Commonly used hinges include swing hinges used on ordinary doors, hydraulic hinges used on fire doors, spring air hinges used on cars, and hinges used on laptop computers. [0003] The damping hinge hinders its relative rotation through the internal structure of the hinge, so that the hinge can be fixed in a specific state. Among them, there are many ways to provide damping. One of the more widely used ways is to apply pressure on two damping materials, and provide damping by the friction between the two damping materials; or through a damping box with damping oil inside, Damping is provided by damping oil; or damping is provided by a spring structure. ...
