Asymmetric buffer hinge and door

Abstract

The invention discloses an asymmetric buffer hinge which comprises a first hinge body, a second hinge body, a connecting piece, a sliding piece, an elastic assembly and a damping assembly. The first hinge body is hinged to the second hinge body so that the included angle between the first hinge body and the second hinge body can be adjusted. The sliding piece can move back and forth in the first hinge main body along with the change of the included angle; one end of the elastic assembly abuts against the first hinge body, the other end of the elastic assembly abuts against the sliding part and synchronously moves along with the sliding part, and the damping assembly can stretch out and draw back along with movement of the sliding part so as to buffer the sliding part. When the asymmetric buffer hinge is in a door opening state, the elastic assembly provides a vertical force or a component force opposite to the target moving direction for the sliding piece, and otherwise, the elastic assembly provides a component force in the same direction as the target moving direction for the sliding piece. The invention further discloses the door. According to the invention, the door can be automatically and slowly closed, the door closing noise is reduced, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of hinges, in particular to an asymmetric buffer hinge and a door. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to the safety, beauty and comfort of shower room products. The swing doors of the existing shower room mainly include the following two: [0003] 1. Door closing without a buffer. This kind of door closing requires the user to manually close the door during use. If the user exerts too much force, the closing noise will be very loud; and the door cannot be closed by buffering the whole process, which is easy to pinch the hand, which will bring great harm to the user. It is inconvenient; at the same time, if the ground level is not handled properly, it is easy to automatically accelerate the closing of the door. [0004] 2. Door closing with a buffer. The spring in this door closing is synchronized with the damping stroke. When ...

AI Technical Summary

Problems solved by technology

[0003] 1. The shutter without a buffer. This kind of shutter requires the user to close the door manually during use. If the user uses too much force, the closing noise will be very loud; and The door cannot be closed with full cushioning, which is easy to pinch hands and cause inconvenience to users; at the same time, if the ground level is not handled properly, it is easy to automatically accelerate the door closing

[0004]Second, the shutter with a buffer. The spring in this kind of shutter is synchronized with the damping stroke. When the stroke is short, the damper is difficult to work. It will even directly affect the damping life

[0005] In view of the above problems, Chinese patent CN113323524A discloses a buffer hinge and a bathroom door, but in this solution, there are too many mechanism nodes between the elastic part and the sliding part, and the use time is too long, which is prone to mechanism wear; and the elastic part Unable to provide continuous power with the sliding parts, prone to abnormal noise, and poor closing feel
