Embodiment Construction

[0031] figure 1 It is a schematic block diagram of an automobile relay simulating automobile motor load test method-synchronous triggering. In the picture:

[0032] Load power supply: provide the required voltage, current and power source for the test load;

[0033] Electronic load: generate a simulated automobile motor load current waveform and generate a load current;

[0034] Coil power supply: provide energy for relay coil excitation;

[0035] Relay: the object to be tested;

[0036] U1, U2: are solid-state relays, which have the advantages of fast action speed and no jitter. Separately drive the electronic load to load and the tested relay to work periodically according to a certain on-off ratio until the end of the test;

[0037] Computer + control + drive: all test parameters, control timing, etc. are stored in the computer, and the computer sends instructions to each part through the controller and driver to coordinate the work of the entire test system.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to a test method for simulating the load of an auto motor on an auto relay. Background technique [0002] Motors are widely used in automobiles, such as wiper motors and window lift motors. Throughout the life cycle of the car, the motor is frequently used in the starting, stalling and stopping states. Automotive relays are usually used to control drive motors. Due to the inductive characteristics of motors, it will have a certain impact on the service life of automotive relays. Therefore, the application life of automotive relays under the load conditions of automotive motors has become an important assessment index for their quality. [0003] The life test of automotive relays under automotive motor load conditions is a method to assess the application life of relays under automotive motor load conditions. The environmental requirements of the test include temperature and hu...
