Abstract

The invention belongs to the technical field of automobile parts, and particularly relates to a damper with overload protection and an electric tail gate support rod. An overload switching seat is arranged on the first side of a cavity of the damper so that the overload switching seat can rotate around a rotating shaft. An overload friction block is arranged on the first side of the overload switching seat by overload steel balls so that the overload switching seat can rotate around the rotating shaft and drive the overload friction block to rotate around the rotating shaft by the overload steel balls. A friction plate is arranged on the first side of the overload friction block. A fixed plate is arranged on the first side of the friction plate and is fixed in the cavity of the damper so that the fixed plate can not rotate around the rotating shaft. A flexible assembly is arranged on the first side of the fixed plate to pressurize on the fixed plate. According to the damper with overload protection and the electric tail gate support rod, the technical defect that an existing electric tail gate support rod does not have the overload protection function is effectively solved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an overload protection damper and an electric tailgate stay. Background technique [0002] The tailgate of the car trunk is an important part of the car, which plays an important role in protecting the passengers or goods inside the car, and the tailgate of the car needs to be opened or closed frequently. When opening or closing the tailgate of the car, it involves the Tailgate power strut. At present, the electric tailgate struts on the market need to hover and can withstand the requirements of fast manual door opening and closing. The current scheme generally uses the static torque of the motor and the friction of the screw, but the existing electric tailgate struts have the following disadvantages: The static torque error of the motor is relatively large, resulting in the risk of inability to hover or excessive manual opening and closing force when using different motors; ...
