Description

Technical Field

[0001] This utility model relates to the field of wire harness testing, and in particular to a combined electric vehicle low-voltage wire harness testing platform. Background Technology

[0002] The low-voltage wiring harness test bench is a specialized device used to test the performance of automotive low-voltage wiring harnesses (voltage level below 60V). It is mainly used to troubleshoot problems such as short circuits, open circuits, and insufficient insulation performance of the wiring harness, ensuring that it meets national standards and OEM technical specifications.

[0003] When testing wire harnesses, the wire harnesses need to be inserted into the testing ports on the testing platform. During testing, the wire harnesses need to be fixed in place to prevent them from loosening. Also, because the wire harnesses are firmly inserted, they need to be dragged forcefully after the testing is completed, which can easily damage the testing platform. Therefore, a combined electric vehicle low-voltage wire harness testing platform is needed. Utility Model Content

[0004] The purpose of this invention is to provide a combined electric vehicle low-voltage wiring harness testing platform to solve the problems mentioned in the background art.

[0006] Preferably, the stabilizing lifting mechanism includes a fixed plate fixedly connected to the inner wall of the main body of the testing platform, a gear rotatably connected to the surface of the fixed plate, and a first rack fixedly connected to the surface of the T-shaped plate, the first rack meshing with the gear.

[0007] Preferably, a top plate is slidably connected to the inner bottom wall of the insertion slot, and a second rack is fixedly connected to the surface of the top plate near the gear, the second rack meshing with the gear.

[0008] Preferably, a plurality of U-shaped plates are fixedly connected to the upper surface of the main body of the testing station, wherein a pair of U-shaped plates are symmetrically distributed around the insertion slot, and a rotating shaft is rotatably connected to the inner wall of the U-shaped plates.

[0009] Preferably, a pressure roller is fixedly connected to the surface of the rotating shaft, a push rod is fixedly connected to the surface of the pressure roller, and a display controller is fixedly installed on the upper surface of the main body of the testing platform.

[0010] Preferably, a torsion spring is fitted onto the surface of the rotating shaft, one end of the torsion spring is fixedly connected to the surface of the U-shaped plate, and the other end of the torsion spring is fixedly connected to the surface of the pressure roller.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] In this invention, a pair of pressure rollers approach each other under the action of a torsion spring, pressing and limiting the surface of the plug to maintain stability during testing. When it is necessary to remove the low-voltage wire harness body from the main body of the testing station, the push rod is pressed, and the pair of pressure rollers move away from each other, pressing down on the T-shaped plate, which drives the first rack to move. The first rack drives the gear to rotate, and the gear drives the second rack to slide upward with the top plate, thereby pushing out the plug in the insertion slot. The advantage of this is that it can ensure the stable positioning of the low-voltage wire harness body during testing and prevent damage to the main body of the testing station when removing the low-voltage wire harness body.

[0025] By setting a second rack 14, which cooperates with the gear 13, the top plate 15 is driven to slide, thereby pushing out the plug 5 located in the insertion slot 4.

[0026] Preferably, a plurality of U-shaped plates 17 are fixedly connected to the upper surface of the main body 1 of the testing station, wherein a pair of U-shaped plates 17 are symmetrically distributed around the insertion slot 4, and a rotating shaft 16 is rotatably connected to the inner wall of the U-shaped plate 17.
