[0016] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively and carefully below in conjunction with the accompanying drawings and preferred embodiments of the specification, but the protection scope of the present invention is not limited to the following specific embodiments.

[0017] like Figure 1-Figure 3 As shown, the present embodiment provides a multifunctional detection platform for automotive wiring harnesses, including a box body 1, the upper end of the box body 1 is open, a detection platform 2 is arranged in the box body 1, the lower end of the detection platform 2 is connected to a first lifting mechanism for driving the detection platform 2 to move up and down, and the fixed end of the first lifting mechanism is fixedly installed on a partition 11 arranged in the box body 1. In the present embodiment, the first lifting mechanism is a first driving cylinder 10 respectively arranged on the four corners of the detection platform 2, the cylinder end of the first driving cylinder 10 is fixedly installed on the partition 11, and the piston rod end is connected to the detection platform 2.

[0018] A harness fixing hole 3 is provided on the side wall of the box 1 above the partition 11. When testing the harness 7, the end of the harness 7 is first placed at the harness fixing hole 3, and the harness is fixed with a sealing block while the harness is sealed and connected to the harness fixing hole 3. The main body of the harness 7 is placed on the testing table 2, and a harness buckle test unit and a harness continuity test unit are installed on the testing table 2. The harness buckle test unit and the harness continuity test unit can use existing equipment, which are components known to those skilled in the art and are not specifically limited in this application.

[0019] A cover plate 4 is arranged above the detection table 2, and a second lifting mechanism for driving the cover plate 4 to move up and down is connected to the lower end of the cover plate 4, and the fixed end of the second lifting mechanism is fixedly mounted on the partition 11. In this embodiment, the second lifting mechanism is a second driving cylinder 5 respectively arranged at the four corners of the cover plate 4. When the cover plate 4 is lowered into place, the cover plate 4 closes the opening at the upper end of the box body 1 and is sealed to the box body 1 through a sealing member, so that a sealed space is formed between the cover plate 4 and the partition 11. In order to keep the partition 11 stable during the lifting process and ensure the accurate docking and matching of the sealing member, a plurality of guide pillars 6 are connected to the lower end surface of the cover plate 4, and the guide pillars 6 are slidably matched with the guide sleeve 13 arranged in the box body 1.

[0020] The box body 1 is also provided with a vacuuming device 12 for vacuuming the sealed space, and an air pressure monitoring unit for monitoring the air pressure in the sealed space. The air pressure monitoring unit is a component known to those skilled in the art.

[0021] A heating device is provided at the lower end of the cover plate 4 . In this embodiment, the heating device comprises resistance heating wires 14 evenly arranged on the lower end surface of the cover plate 4 .

[0022] The box body 1 is also provided with a controller 8 for controlling the electrical components, and a status display unit 9 for indicating the working status of the electrical components. The status display unit 9 may be an indicator light or a display screen.

[0023] When the multifunctional testing platform of the utility model is used, the wiring harness conductivity test and the wiring harness buckle test are first performed through the wiring harness buckle test unit and the wiring harness conductivity test unit on the testing platform 2. After the test is completed, the first driving cylinder 10 drives the testing platform 2 to descend to the set position, and then the second driving cylinder 5 drives the cover plate 4 to move down and seal with the box body 1, and then the sealed space is vacuumed by the vacuum pumping device 12. Since the wiring harness end is placed outside the box, the air pressure change in the sealed space can be detected by the air pressure monitoring unit to achieve the wiring harness air tightness test. When performing the temperature resistance test, the resistance heating wire 14 under the cover plate 4 works to heat the sealed space, simulating the high temperature conditions in the working environment of the car, and detecting the high temperature resistance of the wiring harness.
