Description

Technical Field

[0001] This utility model relates to the field of test bench technology, specifically a simple automotive seat heating wire bending durability test bench. Background Technology

[0002] In today's rapidly developing automotive industry, consumers have increasingly higher demands for car seat comfort. Seat heating has become an important feature for enhancing the driving and riding experience. The core component of a car seat heating system is the heating wire, which is usually made of metal alloy. During actual use, car seats involve frequent sitting, standing, and posture adjustments by occupants, causing the heating wire to be under constant stress from repeated bending and stretching. If the bending durability of the heating wire is insufficient, it is prone to metal fatigue fracture after long-term use. This not only causes the seat heating function to fail, affecting driving and riding comfort in winter, but may also lead to short circuits, leakage, and other safety hazards due to insulation damage at the point of breakage, threatening the personal safety of occupants. Therefore, accurate and efficient testing of the bending durability of car seat heating wires during manufacturing and vehicle assembly is a crucial step in ensuring the reliability and safety of car seat heating systems.

[0003] However, existing bending durability tests for automotive seat heating wires mostly rely on manual simulation tests. Testers manually bend the heating wire samples repeatedly and observe their condition after a specific number of bends. This method requires a lot of manpower and the test results are highly subjective, which cannot meet the requirements for test accuracy and consistency in mass production. Therefore, we propose a simple automotive seat heating wire bending durability test bench to solve the above problems. Utility Model Content

[0022] Example: Figure 1-5 As shown, this utility model provides a simple automotive seat heating wire bending durability test bench, including a base frame 1, a bakelite base plate 2 fixedly installed on the base frame 1 by screws, a pressure strip 3 provided on one side of the top of the base frame 1, an aluminum profile bracket 4 fixedly installed on the top of the base frame 1, an adjusting bracket 41 horizontally installed on the aluminum profile bracket 4 by screws, a telescopic cylinder 5 fixedly installed on the bottom of the adjusting bracket 41 by screws, a connecting plate 51 fixedly installed on the driving end of the telescopic cylinder 5, an upper clamping plate 6 fixedly installed on the bottom of the connecting plate 51, a lower clamping plate 7 provided on the bottom of the upper clamping plate 6, a test sample 8 provided between the lower surface of the pressure strip 3 and the bakelite base plate 2, the end of the test sample 8 away from the pressure strip 3 being movably snapped between the upper clamping plate 6 and the lower clamping plate 7, and adhesive thermocouples 10 evenly arranged on the surface of the test sample 8, the heating state of the adhesive thermocouples 10 is monitored during the test by arranging adhesive thermocouples 10 evenly on the surface of the test sample 8.

[0023] Both ends of the base frame 1 are slidably fitted with first screws 31. The ends of the first screws 31 move through the pressure strip 3. The ends of the first screws 31 are threaded with first nuts 32. The bottom end of the first nuts 32 contacts the upper surface of the pressure strip 3 to fix the position of the pressure strip 3. In this way, one end of the sample 8 to be tested is fixed by the pressure strip 3.

[0024] The lower clamping plate 7 has a second screw 71 vertically installed at both ends. The end of the first screw 31 moves through the upper clamping plate 6. The ends of the second screws 71 are threaded with second nuts 72. The bottom end of the second nuts 72 contacts the upper surface of the upper clamping plate 6. The upper clamping plate 6 and the lower clamping plate 7 are connected by the second screws 71 and the second nuts 72, thereby fixing the other end of the sample 8 to be tested through the upper clamping plate 6 and the lower clamping plate 7.

[0025] The bending durability test bench also includes an auxiliary component 9 for bending and shaping the test sample 8. The auxiliary component 9 includes an arc-shaped frame 91, with a mounting frame 92 fixedly installed on one side of the top of the arc-shaped frame 91. A positioning crossbar 93 is movably installed in the mounting frame 92, and a positioning ring 931 is fixedly installed at the end of the positioning crossbar 93 near the mounting frame 92. The positioning ring 931 contacts the side end of the mounting frame 92. The end of the test sample 8 away from the pressure strip 3 is movably engaged between the outer side of the arc-shaped frame 91 and the positioning crossbar 93 for bending and shaping. A symmetrical crossbar is fixedly installed on the outer side of the arc-shaped frame 91. Two positioning end strips 94 are distributed to position one end of the sample to be tested 8 below the pressure strip 3. Then, the other end of the sample to be tested 8 is bent and placed on the outside of the arc frame 91, and the sample to be tested 8 is placed between the two positioning end strips 94. Subsequently, the end of the positioning crossbar 93 near the positioning ring 931 is movably locked onto the mounting frame 92. The positioning crossbar 93 assists in positioning the bent part of the other end of the sample to be tested 8, which facilitates the subsequent fixing of the other end of the sample to be tested 8 between the upper clamping plate 6 and the lower clamping plate 7 after bending. A handle 911 is fixedly installed at one end of the arc frame 91.

[0026] Working principle: Place one end of the sample 8 to be tested on the upper surface of the bakelite base plate 2, and position and press one end of the sample 8 under the pressure strip 3, and fix it with the first screw 31 and the first nut 32; Subsequently, the other end of the sample 8 to be tested is bent and placed on the outside of the arc frame 91, and the sample 8 to be tested is placed between the two positioning end strips 94. Then, the end of the positioning crossbar 93 near the positioning ring 931 is movably locked on the mounting frame 92. The positioning crossbar 93 is used to assist in positioning the bent part of the other end of the sample 8 to be tested, so that the other end of the sample 8 to be tested can be bent and shaped and then passed between the upper clamping plate 6 and the lower clamping plate 7 and fixed. Subsequently, the positioning crossbar 93 is disassembled, and the arc frame 91 is disassembled by holding the handle 911 to achieve the positioning of the sample 8 to be tested; Subsequently, the telescopic cylinder 5 is activated to control the connecting plate 51 to reciprocate at a certain frequency, thereby driving the other end of the test sample 8 to reciprocate and bend, and performing automatic bending durability test on the test sample 8 to improve the efficiency of bending durability test of automotive seat heating wire. Among them, adhesive thermocouples 10 are arranged at equal intervals on the surface of the sample 8 to monitor the heating state of the adhesive thermocouples 10 during the test.
