specific Embodiment

[0014] In the present invention, the stretching length of the safety belt 10 is controlled by the rotation angle of the servo motor 20, and the rotation angle of the servo motor 20 is set to 20° in the present invention.

[0015] First, manually input the operating frequency, number of cycles and the time of rotation angle of the servo motor 20 into the PC; then take the initial position of the retracted safety belt in the retractor as the starting point, and after the system is powered on, the controller 30 detects the station button 40 is pressed, if pressed, it will go through the delay circuit to debounce; then the controller 30 receives the data of the frequency and cycle times of the servo motor 20 sent by the PC, and after processing, the controller 30 sends pulses to control the servo motor Execute 20 actions; the controller 30 must confirm the data header and the data tail when receiving the data from the PC, and if the confirmation is correct, it will enter the loop o...

Abstract

The invention relates to the field of vehicle part performance detection, in particular to a durability detection system for a seat belt retractor. One end of a seat belt is fixedly wound on a retractor; the other end of the seat belt is connected with a drive mechanism used for stretching the seat belt; a controller controls the drive mechanism to act; the drive mechanism is started to stretch the seat belt to the length when the seat belt is used by a driver or a passenger; the seat belt is imitated to be stretched by a hand, and after the seat belt is pulled repeatedly, the damage degree of the retractor is checked manually, so that the service life of the retractor can be detected; manual action is replaced by a mechanism, so that the workload is reduced greatly; and the system is simple in structure and high in efficiency.

Description

technical field [0001] The invention relates to the field of performance detection of auto parts, in particular to a durability detection system of a safety belt retractor. Background technique [0002] Car seats are one of the essential car parts for car occupants and drivers. When people are driving and riding in cars, car seats carry the weight of our bodies and make us feel comfortable and safe. The seat belt of the car seat plays an important role in protecting the safety of the occupants. The seat belt retractor is an important component of the safety belt restraint system. Its performance directly determines whether the seat belt can protect the vehicle when an accident occurs. Drivers and passengers play a protective role. Therefore, the durability test of the seat belt retractor needs to be carried out during the design and manufacturing process, but there is no durability testing device for the seat belt retractor at present. It brings considerable difficulty to ...
