Knob type shifter high and low-temperature durability test device with gear information monitoring function

Abstract

The present invention discloses a knob type shifter high and low-temperature durability test device with a gear information monitoring function. With the test device adopted, the knob component of a tested knob type shifter is driven to rotate between the first gear position, namely a P gear position and the last gear position cyclically under a set temperature test condition; the knob component is controlled to stop when rotating to each gear position, so that gear information real-time values used for judging the accuracy of gear information can be acquired; a feedback mechanism is adopted, when each rotation test is started, whether the telescopic shaft of a solenoid valve extends out from the tested knob type shifter is detected; and if the telescopic shaft of the solenoid valve extends out from the tested knob type shifter, the solenoid valve is energized under control so as to drive the knob component to perform cyclic rotation for once. With the test device of the invention adopted, when the tested knob type shifter is subjected to a high and low-temperature durability test, the accuracy of the gear information of the tested knob type shifter can be tested. The knob type shifter high and low-temperature durability test device with the gear information monitoring function has the advantages of high reliability of test results and capability of protecting the security of test equipment and the tested knob type shifter.

Description

technical field [0001] The invention relates to a high and low temperature durability test device for a knob-type shifter with a gear information monitoring function. Background technique [0002] The high and low temperature test chamber is a kind of test equipment in the engineering field. At present, as enterprises pay more and more attention to product quality, more products need to pass the high and low temperature durability test before they can be promoted. Therefore, high and low temperature durable equipment is being used more and more widely. [0003] At present, there are the following deficiencies in the high and low temperature durability test of the knob-type shifter: [0004] First, at present, the traditional automotive shifters are mainly in-line and broken-line, and the corresponding operating mechanisms are mostly linear reciprocating motion. However, the knob-type shifter is a rotary motion, and the existing test equipment cannot meet the test requireme...

AI Technical Summary

Problems solved by technology

[0004]First, at present, the traditional automobile shifters are mainly in-line and broken-line, and the corresponding high and low temperature durability test chamber operating mechanisms are mostly linear reciprocating motions

The knob-type shifter is a rotary motion, and the existing test equipment cannot meet the test requirements of the knob-type shifter

[0005]Second, for the shifter, the existing high and low temperature durability test chamber can only test the durability performance of the mechanical structure, and cannot detect synchronously and judge the gear position information in real time accuracy, so that it is impossible to examine the reliability of the electrical performance during the endurance test

[0006]Third, the existing high and low temperature test chambers are mostly open-loop control. As the test progresses, the operating mechanism may deviate or even fail, which will affect the effectiveness of the test In severe cases, it may cause damage to samples and equipment, resulting in test accidents

[0007] Fourth, the existing high and low temperature test chambers can only display limited information such as test temperature, time, and times during the test, and cannot comprehensively monitor the timely rotation of the sample Angle, gear information, solenoid status and other information are not conducive to a comprehensive grasp of design parameters
