Electrical support rod applied to automobile tail doors

Abstract

The invention discloses an electrical support rod applied to automobile tail doors. The electrical support rod comprises an automobile body spherical hinge, an automobile body spherical hinge end cover, a cylinder, a tail door spherical hinge end cover and a tail door spherical hinge, wherein the automobile body spherical hinge end cover is connected with the cylinder through threads; the tail door spherical hinge end cover is connected with the cylinder through threads; a motor and a micro speed reducer are mounted in the cylinder; the motor is connected with a coupler in the micro speed reducer; an output shaft of the micro speed reducer is connected with a screw through the coupler; a jacking pipe is sleeved on the screw; the outside of the jacking pipe is sleeved with a guide sleeve; the guide sleeve is fixed on the cylinder; a telescopic sleeve is mounted on the outer side of the guide sleeve; the head of the telescopic sleeve is connected with the tail door spherical hinge end cover; an auxiliary spring is mounted between the guide sleeve and the telescopic sleeve; one end of the auxiliary spring is welded on the guide sleeve; and the other end of the auxiliary spring is welded on the tail door spherical hinge end cover. The electrical support rod is simple in structure and low in screw deformation; the motor and the speed reducer are not easily overloaded; a central gearis a four-tooth bevel gear; and the overall volume of the electrical support rod is reduced.

Description

technical field [0001] The invention relates to the technical field of an automobile tailgate brace, in particular to an electric brace for an automobile tailgate. Background technique [0002] The tailgate stay is one of the accessories of the tailgate of the car. It is used in conjunction with the control system to realize the automatic opening and closing of the tailgate of the car. Traditional automobile tailgates are generally equipped with gas springs or hydraulic springs, which are supported by the energy storage of compressed gas or hydraulic oil. Manual operation is required to open and close the tailgate, and once the gas spring or hydraulic spring leaks, it will cause The problem of support failure. With the gradual development of automobiles in the direction of intelligence and humanization, more and more mid-to-high-end cars use electric struts to realize the automatic control of the tailgate. [0003] At present, some electric struts use a structure in which ...

Problems solved by technology

[0003] At present, some electric struts use a structure in which the screw rod is directly connected to the drive motor, which is not conducive to the regulation of the opening and closing speed of the tailgate, and the vibration of the motor is directly transmitted to the screw rod, which may easily cause vibration when the tailgate opens and closes

There are also some motors in electric struts that use conventional gear reducers, which are noisy
