Buffer closing device of electric suction door

Abstract

The invention relates to the technical field of electric suction closing doors and discloses a buffer closing device of an electric suction door. A supporting frame makes contact with a rotating rod,the contact positions of the supporting frame and the rotating rod are meshed, an arc-shaped rack can move along with an automobile door, the rotating rod is driven to rotate through the meshing effect between the arc-shaped rack and a gear, a buffer spring is fixedly installed at one end of the gear, and a rotating balancing weight is fixedly installed at one end of the buffer spring. The bufferspring has obvious hysteresis quality in a transmission mode of rotating in the tangential direction, and when the gear rotates, the buffer spring can be elastically deformed; and meanwhile, the elastic force of the buffer spring can act on the rotating balancing weight so as to drive the rotating balancing weight to rotate in a sleeve, and as the mass of the rotating balancing weight is larger than the sum of the mass of the gear and the mass of the rotating rod, rotation of the rotating balancing weight can consume the rotating energy of the rotating rod and the rotating energy of the gear,and the closing speed of the automobile door is reduced.

Description

technical field [0001] The invention relates to the technical field of electric suction closing doors, in particular to a buffer closing device for electric suction doors. Background technique [0002] With the advancement of technology, electric suction doors have begun to be used in some high-end cars. Through the installation of coils inside the frame door frame, when the door is close to the frame door frame, the induction device on the frame door frame will sense that the distance between the door is relatively close. Thereby activating the coil in the door frame of the frame and generating a suction force, which has an adsorption effect on the door and makes it close, thereby reducing the force required to close the door. [0003] However, the penetration rate of electric suction doors is low, and they are rarely seen on common models, and the appearance of electric suction doors is no different from ordinary car doors, so that passengers in the car often do not know t...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing electric suction door proposed in the background technology, the present invention provides a cushioning and closing device for the electric suction door, which has the advantage of being able to decelerate the door when the door is closed vigorously, and solves the problem of the traditional When the electric suction door is closed vigorously, the door will hit the frame door frame at a relatively fast speed, causing damage to the original internal components
