A device and method for correcting the opening and closing track of the back door

Abstract

The invention discloses a back door opening and closing track rectifying device and method. The back door opening and closing track rectifying device comprises a rack. A back door mounting base is slidably connected to the rack in a matched mode. The rack is fixedly connected with a length position adjusting mechanism used for driving the back door mounting base to move horizontally. A back door mounting bracket is slidably connected to the back door mounting base in a matched mode. The back door mounting base is fixedly connected with a height position adjusting mechanism used for driving theback door mounting bracket to move vertically. The back door mounting base is connected with a back door fixed plate which can be opened and closed. A telescopic supporting rod is connected between the back door fixed plate and the back door mounting base. The end of the back door fixed plate is connected with a telescopic back door moving plate. The structure is simple and application is convenient. The device and method ensure operation comfort of the back door with respect to a vehicle rear protection in different positions, heights and radii.

Description

technical field [0001] The invention relates to a correction device for a back door, which belongs to the technical field of car back door tooling, in particular to a correction device and method for opening and closing tracks of a back door. Background technique [0002] With the popularization and expansion of automobiles, people's requirements for the comfort of the back door operation are increasing day by day. In the R&D and design stage of the rear door of a car, the operating comfort of the rear door of various audiences needs to be considered, and the operating comfort of the rear door is directly linked to the opening and closing trajectory of the rear door. At the same time, the opening and closing trajectory of the rear door is It is determined by the installation position of the four-bar hinge on the back door, so how to optimize the installation position of the four-bar hinge on the back door and rationally arrange the opening angle and opening radius of the bac...

AI Technical Summary

Problems solved by technology

[0003] At present, the design method of the installation position of the four-bar hinge on the back door provided in the prior art relies on manually adjusting the installation position of the hinge and the gas spring to ensure the opening track and opening force of the back door. Defects such as time-consuming and labor-intensive; in order to solve the above technical problems, a method and device for determining the installation position of the four-link hinge of the automobile back door are disclosed in the Chinese invention patent CN102930098A. The installation position of the four-bar hinge, but it should be pointed out that the data obtained by the simulation are only theoretical values, which do not consider the special requirements of different audiences (male and female, young and old) on the opening and closing trajectory of the back door, so this The actual installation position of the rear door hinge may not be suitable for specific groups of people. Furthermore, the actual installation process of the rear door hinge may be affected by some parts of the body and needs to be optimized. These are things that cannot be considered in the simulation structure.
