A seat motor self-locking performance testing device

Abstract

The invention discloses a self-locking performance detecting device of a seat motor. The self-locking performance detecting device is provided with a servo motor, a speed reducing mechanism, a torquesensor, a main controller and an angle collecting unit. The servo motor and a tested seat motor are relatively fixed. The output shaft of the servo motor is connected to the output shaft of the testedseat motor by the speed reducing mechanism and the torque sensor; and a control terminal of the servo motor is connected with the main controller electrically. The angle collecting unit collects a real-time rotation angle of the output shaft of the tested seat motor; and the main controller receives a real-time output torque collected by the torque sensor and the real-time rotation angle collected by the angle collecting unit. According to the invention, self-locking performance detection of tested seat motors with different functions in different application scenes is realized. Moreover, theinternal clearance of the tested seat motor is eliminated during the detection process and then a self-locking rotation angle representing the self-locking performance of the tested seat motor is measured. The detection accuracy is high.

Description

technical field [0001] The invention relates to a device for detecting the self-locking performance of a seat motor. Background technique [0002] As one of the key parts of the car, the car seat not only requires a reasonable layout, but also needs to ensure the two major requirements of safety and comfort. For the driver, if the seat position is not suitable, it will have a negative impact on the driver's control sensitivity and line of sight to a large extent, and even cause traffic accidents, which has potential safety hazards. , in order to ensure a wide range of riding comfort as far as possible, the car seat will have various adjustment mechanisms to adjust its position in different directions. [0003] With the continuous improvement of intelligence, electrification and reliability requirements in the automotive industry, seat motors, as an extremely important and complex adjustment mechanism for automotive electric seats, have received more and more attention from ...

AI Technical Summary

Problems solved by technology

However, in general, for car seat motors with different adjustment functions, the self-locking test is carried out through manual adjustment, such as applying a certain size to the output shaft of the seat motor by using a digital display torque wrench or hanging weights. Torque, and it is difficult to control the rate of applied torque, which has limitations to the seat motor self-locking test standards of different manufacturers, and does not meet the current development requirements of modularization, automation and systematization of testing equipment
