The automobile combination switch durability test device has accurate control, It has the advantages of safe use, high test efficiency and stable performance. Its shortcoming is that this kind of durability test device has a complex structure and is inconvenient to use, and it is not suitable for use in durability tests of electric light switch switches and switches of other structures.

Utility model content

In order to overcome the disadvantages of complex structure and inconvenient operation of the durability test device in the prior art, the utility model provides a simple structure, convenient operation, which can effectively test the durability of the electric adjustment system of the car lamp, so as to ensure the The durability test device of the headlight electric adjustment system ensures the stability of the adjustment system and ensures the safety of driving.

In order to achieve the above object, the utility model adopts the following technical solutions:

A durability test device for a car lamp electric control system, comprising a fixing seat, on which a motor is fixed, and a connection structure is provided between the output shaft end of the motor and a trim switch. Through the rotation of the motor to simulate the manual adjustment of the fine-tuning switch, the positive and negative rotation of the motor drives the positive and negative rotation of the fine-tuning switch through the connection structure, thereby changing the resistance change of the entire car light electric adjustment mechanism to make the light and dark of the car light alternately change, so as to test the electric light of the car light. The purpose of the durability of the adjustment mechanism is that the entire test device has a simple structure and is easy to operate. After the durability test of the test device, a qualified and stable car light ESC system is installed on the car. Such a car light ESC system has good stability and can be used. Ensure driving safety.

Preferably, the connection structure includes a roller, one end of the roller is fixedly connected to the output shaft end of the motor, and the side surface of the roller is in contact with the fine-tuning switch. The motor drives the rotation of the roller to simulate the human hand turning the fine-tuning switch up and down.

Preferably, the feature is that the motor is a servo motor, and a motor controller is connected to the motor. The performance of the servo motor is stable and the control is convenient. The forward and reverse rotation of the motor can be accurately realized through the motor controller, so as to change the entire lamp ESC for durability testing.

Preferably, a torque sensor is provided on the output shaft of the motor, and the torque sensor is connected to the motor controller. When the forward rotation of the fine-tuning switch reaches the limit, the torque sensor can sense the small change in the torque of the output shaft of the motor, thereby realizing automatic reverse rotation. Similarly, when the reverse rotation reaches the limit, it will automatically rotate forward again, and the cycle is repeated, so as to realize the automatic realization of the lights. The purpose of the durability test of the ESC.

As a preference, an anti-slip rubber sleeve is provided on the outer side of the roller. The anti-skid rubber sleeve can increase the resistance between the roller and the fine-tuning switch, prevent each other from slipping, and can effectively prevent the roller from wearing the fine-tuning switch.

Therefore, the utility model has the beneficial effects of simple structure, convenient operation, and the ability to effectively test the durability of the electric control system for vehicle lights, thereby ensuring the stability of the electric control system for vehicle lights and ensuring driving safety.
