The invention relates to an automobile seat backrest restoring force testing device which comprises a fixed base plate, a left swing mechanism and a right swing mechanism are arranged on the fixed base plate, a distance is arranged between the left swing mechanism and the right swing mechanism, a balance weight mechanism is arranged in the distance, and the left end and the right end of the balance weight mechanism are connected with the left swing mechanism and the right swing mechanism respectively. A transmission fixing seat is arranged on the fixing base plate, a transmission mechanism is arranged on the transmission fixing seat, the left side and the right side of the transmission mechanism are in synchronous transmission connection with a left swing mechanism and a right swing mechanism through synchronous belts respectively, a driving fixing seat is arranged on the fixing base plate, and a servo motor is arranged on the driving fixing seat. A driving shaft of the servo motor is connected with the torque sensor, the torque sensor is connected with the rotating shaft through the coupler, and the rotating shaft is synchronously connected with the transmission mechanism through the synchronous belt. According to the invention, automatic detection can be realized, so that the working efficiency is improved.
Description
technical field [0001] The invention relates to a test device for the restoring force of a backrest of an automobile seat. Background technique [0002] At present, the existing car seat back will automatically tilt forward after unlocking. At this time, the human body needs to exert a force on it so that the seat can be adjusted backward during use. This force is called the restoring force of the car seat back. The resilience needs to be controlled within a certain range. If the required restoring force is too large, it will be very difficult to adjust the seat back after unlocking; if the required restoring force is too small, the seat will suddenly fall backward after unlocking, which is very dangerous during driving. [0003] Going back to the production of the car seat back, it is necessary to check whether the restoring force meets the safety standard after the car seat back is manufactured. The current testing institutions for the restoring force of car seat backres...
