Automobile two-cover outer-mounted durable test stand

Abstract

The invention relates to an external endurance test bed with two covers for an automobile, which comprises a bench and the following components: a master cylinder arranged in the bench, a first upwards-pulling rope one end of which is fixedly connected with a piston rod of the master cylinder, while the other end is connected with an automobile cover; a countercylinder arranged in the bench, and the end part of the piston rod of which is connected with one upwards-pulling movable pulley; a second upwards-pulling rope one end of which is fixed on the bench and passes through the upwards-pulling movable pulley and at least one upwards-pulling dead pulley, while the other end is connected with the automobile cover; a first downwards-pulling rope one end of which is fixedly connected with the piston rod of the master cylinder and passes through at least one transitional dead pulley, while the other end is connected with a downwards-pulling movable pulley; and a second downwards-pulling rope one end of which is fixed on the bench and passes through the downwards-pulling movable pulley and at least one downwards-pulling dead pulley, while the other end is connected with the automobile cover. The external endurance test bed has the advantages of high reliability, low cost and small volume.

Description

technical field [0001] The invention relates to an automobile test device, in particular to a test bench for testing the opening and closing durability of a front engine compartment cover and a rear trunk cover of an automobile. Background technique [0002] Usually, the test bench for the two covers (front engine compartment cover and rear trunk cover) of the car is a built-in form. The test must use the body in white, and the main and auxiliary cylinder mechanical structures with opening and closing functions are installed inside the empty two compartments. , soft rope cable mechanism to complete the test. Due to the durability test benches installed inside the two compartments, the tests can only examine the torque loosening of the hinges and fixing bolts of the two covers, and the durability tests of the locks and gas springs in high and low temperature environments. [0003] The durability test standards of each automobile manufacturer are different. SAIC's first Roew...

AI Technical Summary

Problems solved by technology

[0004] The existing two-cover external durability test bench mainly uses four channel steels as columns to form a huge frame placed outside the vehicle. The main cylinder is controlled by PLC to lift the two covers, and the auxiliary cylinder closes the two covers. It is bulky and cannot be moved to the environmental chamber, and the durability test can only be done at room temperature. With this solution, it is impossible to meet the test standards of the Roewe series models. The external double-cover durability test bench must be removable in the environment. In order to meet the requirements of the comprehensive double-cover test
