Test machine for testing aligning torque of manually operated recliner of automobile seat

Abstract

The invention relates to a test machine for testing the aligning torque of a manually operated recliner of an automobile seat. The test machine for testing the aligning torque of the manually operated recliner of the automobile seat is characterized by comprising a testing device and a framework device which are connected with each other. The testing device comprises a lower worm gear case, a lower worm gear case hand wheel, a rotating seat, a base board, a rotating fixed block, a rotating shaft, an upper worm gear case, an upper worm gear case hand wheel, a sensor rotating framework, a force sensor, a fixed plate, a sense displayer and an automatic angle measurer. The framework device comprises a recliner mounting seat base board, a recliner mounting seat, a recliner lower board, a recliner upper board, a simulation framework sensor stress board and a simulation backrest framework. The lower worm gear case and the rotating seat are fixed on the base board, the upper worm gear case and the framework device are fixed on the fixed plate, the base board, the rotating fixed block, the fixed plate, the sensor rotating framework and the force sensor are arranged from bottom to top in sequence, and the base board, the center axis of the rotating shaft and the fixed plate are parallel to one another. The test machine for testing the aligning torque of the manually operated recliner of the automatic seat is simple in design, reasonable, compact, accurate, reliable and long in service life. Further, the test machine can be used for testing the aligning torque of the manually operated recliner of the automobile seat conveniently.

Description

technical field [0001] The invention relates to a testing machine, in particular to a testing machine for the return torque of a manual seat recliner, which belongs to a test device and is used for testing the return torque of a manual seat recliner. Background technique [0002] The car seat recliner is a device installed on the car seat to adjust the angle of the seat back. The return torque of the manual seat recliner refers to: fix the simulated backrest frame with the recliner assembly on the rigid fixture, adjust the simulated backrest frame back and forth for at least one cycle, and then adjust the simulated backrest frame to the end. Unlock the recliner, place a dynamometer on the simulated backrest frame, release the simulated backrest at a constant speed, the torque from the dynamometer reading to the turning point is the return torque of the manual recliner; the measurement results should meet the requirements agreed upon by both parties. [0003] In the prior ar...
