An Endurance Test Device for Engine Compartment Hinges

Abstract

The invention provides an endurance test device for an engine compartment cover hinge, which belongs to the technical field of automobiles. It solves the problem that the existing durability test device cannot automatically close the engine cover, and cannot simulate the action of closing the engine cover in a real environment. The durability test device of the engine compartment cover hinge includes a support stand and a support hinged on the support stand. The support is connected with a rope chain that can be connected with the engine compartment cover. The cylinder one that engine compartment cover is opened, is also provided with the auxiliary structure that stops and falls again when engine compartment cover falls to a certain height on the support stand. The auxiliary structure can make the engine compartment cover stop when it falls to a certain height and fall again, help the engine compartment cover to close correctly, simulate the closing process of the engine compartment cover more realistically, and make the test data more accurate.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to an automobile test device, in particular to an endurance test device for an engine hatch hinge. Background technique [0002] In the current domestic automobile production, the quality of the bonnet hinge is very important. After the engine hatch and hinges are installed on the car body, many problems need to be paid attention to: whether the hinge itself will interfere when the hatch is opened and closed, and whether the hinge will be worn and broken after a long time. For these problems, the most important means of inspection is to carry out durability tests during manufacture, and hinges generally undergo strength and durability tests of more than 100,000 times. [0003] [CN201220267834.5], a kind of engine cover hinge test device announced by Chinese patent, includes a mounting bracket, the mounting bracket is connected to the cylinder barrel of the cylinder, the piston ro...

AI Technical Summary

Problems solved by technology

After the engine hatch and hinges are installed on the car body, many problems need to be paid attention to: whether the hinge itself will interfere when the hatch is opened and closed, and whether the hinge will be worn or broken after a long time

This device retracts the cylinder when the engine cover needs to be closed, and the cover loses support and should automatically fall. However, due to the large area of ​​the engine cover, and the cover is also connected with the pull rope, it is affected by the traction force of the pull rope and the air resistance during the fall. The function, the speed is uniform, the engine cover cannot be closed automatically, and the action of simulating the closing of the engine cover in the real environment cannot be achieved.
