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 ...
