Electric tail door strut spring high-/low-temperature durability device

Abstract

The invention relates to an electric tail gate strut spring high- / low-temperature durability device. Upper and lower cylinders in a box are connected by a triangular rib connecting frame. A spring guide rod is sleeved with a spring, and the bottom end is fixed on a bottom plate through a fixing seat. A guide rail can slide up and down along a guide rail column. The lower cylinder and the guide rail column are fixed on the bottom plate. The bottom plate is fixed at the bottom of the box. The upper cylinder and the guide rail are fixed below a first pressing plate. A second pressing plate is arranged above the first pressing plate. Two limit screws are arranged below the second pressing plate. The limit screws pass through the first pressing plate, and carry out limiting through limit nuts.The top of the spring guide rod passes through the first pressing plate and the second pressing plate to contact the bottom of an upper cover. The durability device can effectively simulate the life durability of a spring at different temperatures, and can provide reliable evidence for the effect of temperature on a spring in an electric tail gate strut.

Description

technical field [0001] The invention relates to a durable device, in particular to a high and low temperature durable device for an electric tailgate stay spring, and belongs to the technical field of automobile electric tailgate stay manufacture. Background technique [0002] Cars are already the first choice for people's daily life and transportation. More and more cars have entered the family and life. Due to the needs of the society, the functionality of cars has also increased. For example: the smartness of the electric tailgate of the car is much more convenient, and it saves the need to open it with both hands. As long as you press it easily, the electric strut will complete the opening and closing of the tailgate. The electric strut uses electric energy to convert into mechanical energy, and at the same time uses a compression spring to give a certain force and reaction force to complete the opening and closing of the tailgate. The compression spring is an important ...

AI Technical Summary

Problems solved by technology

However, because the compression spring belongs to the metal rigid class, it will be corroded due to many factors. Although many manufacturers adopt a series of preventive measures such as flocking and tin plating, the temperature is still unable to be prevented, and it cannot be accurately calculated in the existing technology. The spring of the strut is affected by the temperature, and the service life is durable
