Pinch resisting door for automobile

Abstract

The invention discloses a pinch resisting door for an automobile, which comprises a movable door and a door frame, wherein the movable door and the door frame are connected through a hinge; a hand pinch resisting device is arranged on the movable door; the hand pinch resisting device comprises a fluid cylinder, an electromagnetic valve, a limit switch and a controller; when a piston rod is in contact with the door frame, the rotation of the door can be hindered by utilizing the elasticity of a spring in the fluid cylinder, and the door closing speed is lowered; and when the movable door is closed until a limit rod of the limit switch is in contact with the door frame, the movement of a piston and the piston rod can be hindered by utilizing hydraulic oil sealed in a left cylinder of the fluid cylinder, the pressure of hydraulic oil boosts continuously to generate the flexible resistance force so as to hinder the movement of the piston and the piston rod, the piston rod is utilized to hinder the rotation of the movable door, the door closing speed is lowered, the time that a child withdraws a hand from the door frame can be prolonged, and the hand of the child can be protected from being injured by the door.

Description

Technical field [0001] The invention relates to an anti-pinch door, in particular to an anti-pinch door for automobiles. Background technique [0002] Existing car doors, when the door is closed with too much force, the door will be closed quickly with the help of inertia, and the impact of closing the door is relatively large. If a child or an old man puts his hand on the door frame, the hand cannot be retracted in time, and the movable door of the car is easy to pinch the child. or the hand of an old man. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, provide an anti-pinch door for automobiles, slow down the speed of closing the door, reduce the impact force of closing the door, and prevent the movable door of the automobile from pinching the hands of children or the elderly. [0004] The technical solution adopted by the present invention is: the automobile anti-pinch door includes a dodge door ...
