Novel automobile electric side-opening door driver

Abstract

A novel automobile electric side door opening driver comprises a shell, a motor assembly, a lead screw assembly and a push rod, and the shell can be installed on an automobile side door; the motor assembly comprises an output shaft extending into the shell; the screw rod assembly is arranged in the shell and comprises a screw rod and a sliding block which is in threaded connection with the screw rod, and the screw rod is in transmission connection with the output shaft; the push rod is movably arranged on the shell in a penetrating manner; central shafts of the output shaft and the screw rod are perpendicular to each other; the screw comprises an input end and an output end, the input end is sleeved with a worm gear, and the output shaft is connected with a worm; the input end of the screw extends towards the side away from the output end to form a damping part, and a damper assembly is arranged on the damping part in a matched mode. The output shaft of the motor is perpendicular to the center shaft of the screw, transmission is achieved between the output shaft of the motor and the center shaft of the screw through cooperation of the worm gear and the worm, hovering can be achieved even if the motor loses power when the vehicle door is opened and closed, and the stability of the hovering function of the vehicle door is further improved due to the arrangement of the damper assembly.

Description

technical field [0001] The invention relates to the technical field of automobile side doors, in particular to a novel automobile electric side door driver. Background technique [0002] Automobile side door electric opening system, also known as automobile electric door, is generally referred to as electric door. Push and pull to complete the door opening and closing; [0003] The existing driver used in the electric opening system of the automobile side door is generally composed of a motor and a screw rod. The screw of the screw rod is driven by the motor to rotate, and then the slider of the screw rod can be displaced relative to the screw rod. The slider of the rod is connected to the car body, or a push rod is added to the slider, and then the push rod is connected to the car body, so as to realize the electric opening and closing of the side door; [0004] In the existing solution, there are two main ways of connecting the motor and the screw rod; the first one: the...

AI Technical Summary

Problems solved by technology

[0005] The driving mechanism of the automobile door mentioned in the above-mentioned patent, but this structure has the following problems: first, according to the connection mode of the motor and the screw rod of the existing driver, when the motor is accidentally disconnected during the opening and closing of the car door Electricity, the door cannot be hovered, and the involuntary closing of the door is likely to cause a safety accident; second, the motor and the screw on the same axis will cause the length of the entire drive to be too long, making it possible to apply There are few models; third, the transmission between the motor and the screw rod is achieved by a reduction gear set. If you want to achieve the required transmission ratio, you need multi-stage transmission to achieve it, which will further increase the size of the drive.
