Force testing device of shift lever

Abstract

The invention relates to a force testing device of a shift lever. The force testing device of the shift lever comprises a bracket, force arms, a stepper motor, a traction rod, a shift head guiding sleeve, a shift head pushing rod, a motor base, a displacement sensor, a rear displacement sensor support, a front displacement sensor support, a shift head slide block, a lower clamp plate, a lever shaft, a wheel, a wheel axle, a bearing, a pressure sensor and an upper clamp plate. The force testing device of the shift lever has the beneficial effects that: with the adoption of the design of the force arms which are symmetric at the two sides, the force arms are connected by a spring, so that the shift lever is uniformly stressed, and the touch effect is simulated well when the shift lever is pushed by a hand; moreover, two force arms are designed, so that the position of a testing component is fixed once by a user during testing, and the position of the testing component does not need to be changed during the test of the return force; and meanwhile, the displacement of the shift lever can be accurately tested by the displacement sensor according to the displacement of the shift lever, the forces are in one-to-one correspondence with the displacements, and the force at each position during the travel of the shift lever can be clearly seen, thereby providing convenience for a designer to amend the testing component.

Description

technical field [0001] The invention belongs to the field of testing instruments and meters, and in particular relates to a driving rod force testing device. Background technique [0002] At present, for many lever and slider switch control parts, many manufacturers basically think that the operation is simple, and the operation force is not very large. They think that it will not affect the sales of the products, and seldom carry out detailed inspections on them. The main reason is that there is no corresponding device for testing the lever force on the market, which causes manufacturers to ignore the lever test piece. In this regard, we have designed a lever force test device to test the force of the test piece lever and the stroke of the lever, and at the same time measure the displacement corresponding to the position of the maximum force and the minimum force of the lever. In this way, the corresponding data can be measured according to the requirements of the test pie...

[0002] At present, for many switch control parts such as levers and sliders, many manufacturers basically think that the operation is simple, and the operation force is not very large. They think that it will not affect the sales of the products, and seldom carry out detailed inspections on them.

The main reason is that there is no corresponding device for testing the force of the lever on the market, which leads to the neglect of the lever test piece by the manufacturer.
