Method for testing performance of four doors and one cover of pure electric vehicle

Abstract

The invention discloses a method for testing the performance of four doors and one cover of a pure electric vehicle. A test bench is included, the test bench is composed of a mechanical system, an electrical control system and a measurement and control system, the mechanical system comprises an engine cover opening and closing mechanism and a side door opening and closing mechanism, the engine cover opening and closing mechanism comprises a support body, a rotating module composed of an air cylinder driving mechanism, a simulation mechanical arm and an internal and external unlocking mechanism is arranged in the support body, and the electrical control system comprises a control computer, a data acquisition card, a current sensor, a position sensor, a force sensor, an electromagnetic valve, an air cylinder, a sensor power supply, a circuit breaker and a contactor. By arranging the side door opening and closing mechanism and the engine cover opening and closing mechanism, four doors and one cover of different vehicle types can be tested, and meanwhile, the testing method is convenient, feasible and effective.

Description

technical field [0001] The invention relates to the technical field of pure electric vehicle testing, and more specifically relates to a test method for the performance of four doors and one cover of a pure electric vehicle. Background technique [0002] Before the car goes on the market, it is necessary to carry out a function realization test on the front and rear covers, left and right doors of the car. The test content includes the rationality of the shape and structure of the four doors and two covers of the passenger car and the associated door locks, hinges, Sealing strips, retaining strips, locks, inward opening handles, outward opening handles and the mechanical properties of the central control. Therefore, most of the test benches in the market are developed and manufactured based on the standards of passenger cars, so it is particularly important to develop and test a test bench for verifying the durability of miniature pure electric vehicle trucks based on the pa...
