Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts testing equipment, and in particular to a simple bending test device for automotive seat heating pads. Background Technology

[0002] Car seat heating pads are an important component for improving the comfort of car passengers. During long-term use, they will be repeatedly bent due to seat adjustment, passengers sitting and getting in and out, road bumps, and seat movement. If the heating pad has problems such as broken wires or structural damage during bending, it will directly affect the heating function and even cause safety hazards. Therefore, bending tests of heating pads are very important.

[0003] In existing technologies, bending test equipment is generally modified from wire bending test devices for temporary use. There is no bending test device specifically designed for seat heating pad assemblies, resulting in relatively complex operation and high equipment costs. If manual repeated bending of the heating pad is relied upon to simulate usage scenarios, this method has two major problems: First, it is difficult to maintain consistent force, angle, and frequency of manual operation, leading to poor repeatability of test results and an inability to accurately reflect the durability performance of the heating pad; second, the testing efficiency is extremely low, especially in batch testing scenarios, making it difficult to meet production schedule requirements. Therefore, there is an urgent need for a device that can automatically and accurately complete the bending test of the heating pad, and is low in cost and easy to operate. Utility Model Content

At this time, the external air source is connected through the first air inlet 211 of the pressure gauge, and the pressure gauge 212 displays the air pressure. The air flows from the first air outlet 213 through the air pipe 224 to the second air inlet 221 of the solenoid valve 22.

Then, the air flows through the connecting piece 13. 1. The second round bar 132 is driven to rotate 180 degrees back and forth, causing the heating pad 3 to flip along the first round bar 121 on the fixed plate 122. Then, the required number of bending cycles can be set, recorded, reset and displayed through the setting button 261, selection button 262, reset button 263 and screen 264 on the counter 26. During the test, the on and off time can be set through the time relay 25, and the intermediate relay 24 can transmit the control electrical signal of the time relay 25 to the solenoid valve 22, thereby controlling the on and off of the air circuit. The pressure gauge 21 can detect the air circuit pressure to ensure that the air pressure is within the normal range. When there is a safety hazard, the emergency stop switch 28 can be pressed to shut down the equipment in an emergency to ensure safety. This realizes automated and standardized testing, improves the testing accuracy and efficiency, and reduces costs and operating difficulty.
