Torque detection device for automobile seat angle adjuster

Abstract

The invention relates to a torque detection device for an angle adjuster of an automobile seat, which comprises a torque sensor, a flexible coupling, a reducer, a driving motor and a torque measurement instrument. The device is characterized in that the device also comprises a fixed end of a cross fork shaft, a free end of the cross fork shaft, a petal basket of the angle adjuster, and a fixture, wherein four pin shafts of the fixture are inserted into four fixing holes at the lower end of a frame of the automobile seat and are fixed, a forkhead of the pedal basket of the angle adjuster is connected with the free end of the cross fork shaft for eliminating eccentric distance produced during the rotation, the fixed end of the cross fork shaft is arranged on a bearing support, an output shaft of the cross fork shaft is connected with an output shaft at one end of the torque sensor through the flexible coupling, an output shaft at the other end of the torque sensor is connected with the reducer and the driving motor through the flexible coupling, and the torque sensor is connected with the torque measurement instrument through a signal wire. The device has the advantages of high automation degree, convenient operation, reliable movement, simple structure, and convenient maintenance.

Description

technical field [0001] The invention relates to a torque detection device, in particular to a device for torque performance detection of an automobile seat recliner. Background technique [0002] The country has promulgated a series of standards for the performance of car seats, one of which is the torque performance index of the seat recliner. It is required that after the installation of the car seat recliner is completed, turn the recliner, the seat back will reciprocate at a certain speed within the specified angle stroke, and detect the torque value to judge its eligibility. At present, there is no such testing device in China. For this testing content, manual testing can only be carried out, or this testing will not be done. Manual inspection means turning the seat recliner manually, and judging whether it is qualified or not based on hand feeling or experience. Not only is the labor intensity of workers high, time-consuming, and work efficiency is low, but also the r...

Problems solved by technology

Manual inspection means turning the seat recliner manually, and judging whether it is qualified or not based on hand feeling or experience. Not only is the labor intensity of workers high, time-consuming, and work efficiency is low, but also the reliability of the detected parameters is low, and there is no data to indicate its torque value. The size of the product does not meet the product testing standards
