Description

Car seat recliner torque detection device

technical field

The invention relates to a torque detection device, in particular to a device for torque performance detection of an automobile seat recliner.

Background technique

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 reliability of the detected parameters is low, and there is no data to indicate its torque value. The size does not meet the product testing standards.

Contents of the invention

The invention aims to provide a torque detection device for a car seat recliner, which is used to improve the automation degree and parameter reliability of the torque performance detection of the car seat recliner, and to meet the requirements of national testing standards.

The object of the present invention is achieved like this: a kind of car seat recliner torque detection device, comprises torque sensor, flexible coupling, speed reducer, driving motor, torque measuring instrument, it is characterized in that: also comprises cross shaft The fixed end, the free end of the cross fork shaft, the recliner flower basket, tooling, the four pins of the tooling are inserted into the four fixing holes at the lower end of the car seat frame and fixed, the fork of the recliner flower basket and the free end of the cross fork shaft The connection is used to eliminate the eccentricity generated during rotation. The fixed end of the cross fork shaft is installed on the bearing support, and its output shaft is connected with the output shaft at one end of the torque sensor through a flexible coupling. The shaft coupling is connected with the reducer and the driving motor, and the torque sensor is connected with the torque measuring instrument through the signal line.

The seat recliner torque detection device is installed on one side of the seat frame recliner flower basket after the seat recliner is installed; when the drive motor is working, the torque of the seat recliner is transferred to the The large and small signals are output to the torque measuring instrument, and real-time monitoring, storage, and printing are realized on the torque measuring instrument interface.

The beneficial effects of the present invention are:

The invention is driven by a motor, and the seat recliner is driven to rotate through a reducer, a sensor, a connecting piece, and a cross shaft, which completely simulates the working state of the recliner in a real vehicle, and eliminates the eccentricity of the seat recliner during detection. Eccentric torque, high degree of automation, convenient operation, reliable movement, simple structure of the whole device and easy maintenance. The measured value is accurately transmitted to the torque measuring instrument by the torque sensor, and the real-time monitoring is carried out by the torque measuring instrument. The torque value displayed by the torque tester during testing can be stored, printed, and an alarm can be given when the torque value exceeds the limit value. Based on this, it is judged whether the torque performance of the car seat recliner product is qualified or not, and meets the requirements of the national testing standard.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

As shown in Figures 1 and 2, a torque detection device for a car seat recliner of the present invention includes a tooling 1, a seat recliner 2, a seat frame upper body 3, a flower basket yoke 4, and a bearing support 5 , rolling bearing 6, torque sensor 7, flexible coupling 8, reducer 9, drive motor 10, torque measuring instrument 11, signal line 12, workbench 13, fixed end of cross fork shaft 14, free end of cross fork shaft 15, adjustment Corner flower basket 16, seat frame lower body 17, limit switch 18.

Install a pair of tooling 1 with pins on the car seat assembly line workbench 13, embed the four fixing holes of the lower body 17 of the car seat frame into the four pins of the tooling 1 to fix it, and the upper body of the car seat frame 3. The flower basket 16 of the recliner can be rotated to swing back and forth, simulating the actual vehicle installation state of the car seat, and the flower basket fork 4 is embedded on the flower basket 16 of the recliner. The flower basket fork 4 is connected with the free end 15 of the cross shaft, and the cross fork The free end 15 of the shaft can rotate and swing to a certain extent around the center to adjust the eccentricity generated when the seat recliner 2 rotates. The free end 15 of the cross shaft is connected with the fixed end 14 of the cross shaft through a pin, A pair of rolling bearings 6 are installed on the shaft fixed end 14 to match the bearing support 5 and installed on the workbench 13. The two rolling bearings 6 are separated by a certain distance, which can convert the eccentric torque that may be transmitted again into rolling friction torque, so that the cross The torque transmitted by the shaft fixed end 14 is pure torque, the output shaft of the cross shaft fixed end 14 is connected with the output shaft at one end of the torque sensor 7 through the flexible coupling 8, and the output shaft at the other end of the torque sensor 7 is connected through the flexible coupling 8 Connect with the reducer 9, the reducer 9 and the drive motor 10 are integrated, when the drive motor 10 is working, through the above transmission chain, the torque signal generated by the rotation of the seat recliner 2 passes through the signal line 12 on the torque sensor 7 Transmission to the torque measuring instrument 11, the torque measuring instrument 11 can monitor the force state when the seat recliner 2 rotates during the seat swing process in real time, and can set an over-value alarm, store each detection data and print. The swing angle of the seat frame upper body 3 can be preset on the workbench 13 by the limit switch 18 according to standard requirements.
