Description

Bidirectional transmission type supporting device

Technical Field

The application belongs to the technical field of car tail-gate vaulting pole, especially relates to a two-way transmission formula strutting arrangement.

Background

Currently, tail gate lifting devices of vehicles such as SUVs or MPVs are mostly realized by means of gas struts (or gas springs). The air stay bar has the advantages of low price, light weight, small size, convenience in installation and the like, and is widely applied to an automobile tail door lifting system. The gas strut has many advantages and also has obvious disadvantages, for example, the gas strut is filled with compressed gas in the structure, and the lifting force provided by the gas strut is sensitive to the change of the environmental temperature; in addition, in response to the trend of motorization of automobiles, the gas strut is difficult to become an actuating mechanism directly controlled by an electric control system due to the structural characteristics of the gas strut.

Because the structure adopts the motor driving and reducing system, the application of the electric stay bar is often limited by the sizes of the motor and the reducing system due to a plurality of factors such as the weight of the tail gate of the automobile, the mechanical property requirements of opening and closing the gate and the like. For example, a larger diameter is easy to interfere with the characteristics of the bracket for fixing the stay bar, the water flowing groove of the tail gate and other parts, and simultaneously, the rotating speed of the motor is relatively high due to the unidirectional transmission in the length direction and the requirement of the industry on the time for electrically opening and closing the gate, so that the problems of noise, vibration and the like are derived. For example, in patent CN106761138B, a fixed sleeve is fixedly mounted on one side of the first outer tube close to the first end cap, and a shaft positioning assembly for preventing the lead screw from popping up and separating from the transmission case under the action of the spring assembly is mounted on the fixed sleeve; the outer wall of one side, close to the second end cover, of the first outer pipe is provided with guide protrusions extending along the axial direction at intervals along the circumferential direction, and the whole section of the inner wall of the second outer pipe is provided with guide grooves matched with the guide protrusions on the first outer pipe along the axial direction.
