Problems solved by technology

When the parameters of the four-bar linkage or the position of the installation point of the gas spring or the force value of the gas spring change, the results need to be recalculated, which is cumbersome
[0003] In view of the above problems, it is very necessary to quickly select the optimal solution in the feasible layout space, so as to avoid the defects of large opening force of the back cover and the waste of later mold repair costs caused by layout problems.

Embodiment Construction

[0032] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment of various embodiments of the present invention.

[0033] The present invention inputs the coordinates of the four points of the four-link hinge, the coordinate of the gas spring installation point, the coordinates and weight of the center of gravity of the trunk lid, and the force value of the gas spring in the program interface, and the trunk lid can be conveniently and quickly calculated when the trunk lid is opened at different opening angles. The gravitational moment and the gas spring moment can be drawn, and the moment curve can be drawn; the program has a data export function, which can convert the gravitational moment, gas spring opening moment, gas spring closing moment, gravity arm, gas spring arm, etc. Export to excel to facilitate the comparison and analysis of the calculation results of different layout schemes in excel, and to select...

Abstract

The invention relates to a design method for a gas spring four-link hinge of a trunk lid, comprising the following steps: inputting and calculating required four-link hinge parameters on a program interface; Center, the coordinates of the movable installation point of the gas spring during the opening process, the coordinates of the center of gravity of the rear cover during the opening process, etc.; calculate the gravity moment and gas spring moment of the trunk lid at different opening angles; compare and analyze the calculation results of different layout schemes; select Appropriate arrangement. It is convenient to compare the calculation results of different layout positions and choose the optimal solution. The calculation result is accurate and fast.

Description

Technical field [0001] The invention relates to the hinge arrangement of a car, in particular to a parameterized design that can be realized when a gas spring four-link hinge is adopted for the trunk lid of a car. Background technique [0002] At present, when a gas spring four-link hinge is used in the trunk lid of a car, the transient rotation center, gas spring lever arm, and gravity lever arm of the trunk lid mainly rely on catia drawing method, combining the gas spring lever arm and gravity at different positions. The moment arm calculates the gas spring moment and gravity moment. When the four-bar linkage parameter or the gas spring installation point position or the gas spring force value changes, the result needs to be recalculated, which is cumbersome. [0003] In view of the above problems, it is very necessary to quickly select the optimal solution in a feasible layout space, which can avoid defects such as large opening force of the rear cover caused by layout problems...
