[0025] Embodiment

[0026] As Figures 1 to 5 The utility model discloses a quick dismounting structure's electric motor car wire harness subassembly has, including first power cord 1 and second power cord 2, the one end of first power cord 1 is equipped with first connector 11, and the one end of second power cord 2 is equipped with second connector 21, still includes: the fixed sleeve of first connector 11 on fixed sleeve 12;The first connector 11 and second connector 21 are inserted and connected after the clamping lever mechanism of installation on second connector 21 is automatically locked;The rebound mechanism is set up in the one end of second connector 21 close to fixed sleeve 12 and automatically separates first connector 11 and second connector 21.

[0027] Further, the clamping lever mechanism includes the quick release sleeve 3 of fixed sleeve in second connector 21, a pair of rotary clamping grooves 31 are set up on quick release sleeve 3, and a pair of rotary grooves 32 are set up on quick release sleeve 3 and are communicated with corresponding rotary clamping grooves 31, the rotary lever 33 is rotatably connected in the inside rotary groove 32, and the one end of rotary lever 33 is fixedly connected with the resistance clamping head 34 that clamps fixed sleeve 12 and generates prompt sound, and when resistance clamping head 34 automatically clamps fixed sleeve 12, the sound of "click" appears.The end of resistance clamping head 34 close to fixed sleeve 12 is provided with the arc head that drives rotary lever 33 to automatically open after abutting against fixed sleeve 12, and the arc head is so that resistance clamping head 34 can be automatically clamped after abutting against fixed sleeve 12.

[0028] Among them, the clamping lever mechanism further includes the pressing block 35 of fixed connection in the other end of rotary lever 33, and the upper surface of pressing block 35 is fixedly connected with a plurality of linearly arranged antiskid stripes 36, and antiskid stripes 36 increase the friction of the surface of pressing block 35, help user more firmly press down pressing block 35.Especially in the case of hand sweating or environment wet and slippery, antiskid stripes 36 can prevent finger sliding, thereby ensuring the accuracy of operation.The inside of rotary clamping groove 31 is fixedly connected with reset spring 37, and reset spring 37 is so that the pressing block 35 pressed by hand restores to the original position, and the pressing block 35 that restores to the original position will eventually drive resistance clamping head 34 to be always in the state of clamping fixed sleeve 12.The end of reset spring 37 away from the inner wall of rotary clamping groove 31 is fixedly connected with pressing block 35.

[0029] Secondly, the rebound mechanism includes a force-storing telescopic groove 38 formed at the end of the second connector 21 near the fixed sleeve 12. A sliding sleeve 381 is slidably connected inside the force-storing telescopic groove 38, abutting against the fixed sleeve 12. After the sliding sleeve 381 abuts against the fixed sleeve 12, the force is evenly distributed, preventing the uneven force that occurs during manual insertion and removal. Multiple force-storing springs 382 arranged in a circumferential array are fixedly connected inside the force-storing telescopic groove 38. The force-storing springs 382 cause the sliding sleeve 381 to quickly abut against the fixed sleeve 12, subsequently causing the fixed sleeve 12 to move the first connector 11 away from the second connector 21. The ends of the force-storing springs 382 away from the inner wall of the force-storing telescopic groove 38 are all fixedly connected to the sliding sleeve 381.

[0030] Furthermore, a pair of rotating slots 31, rotating grooves 32, rotating rods 33, abutting heads 34, pressing blocks 35, anti-slip stripes 36, and return springs 37 are all symmetrically arranged on the quick-release sleeve 3.

[0031] In this embodiment, when using an electric vehicle wiring harness assembly with a quick-release structure, such as... Figure 1 As shown, the first power cable 1 and the second power cable 2 need to be quickly disconnected as follows: Figure 2 As shown, simply squeeze the pair of pressing blocks 35 simultaneously. The pressing blocks 35 drive the rotating rod 33 to rotate within the rotating groove 32. The end of the rotating rod 33 away from the pressing blocks 35 causes the abutment head 34 to open until it can no longer hold the fixing sleeve 12 on the first connector 11. At this time, the sliding sleeve 381 in the energy storage groove 38, through the elastic thrust of multiple energy storage springs 382, ​​pushes the fixing sleeve 12 away from the second connector 21. This causes the fixing sleeve 12 to disengage the first connector 11 from the second connector 21, thus quickly and easily disassembling the first power cable 1 and the second power cable 2. When it is necessary to quickly install the first connector 11 on the first power cord 1 and the second connector 21 on the second power cord 2, simply plug the first connector 11 and the second connector 21 together. The second connector 21 will then move the quick-release sleeve 3 toward the first connector 11 until a pair of abutting heads 34 on the quick-release sleeve 3 abut against the fixed sleeve 12. At this point, the arc-shaped head at the end of the abutting head 34 will automatically lock into the fixed sleeve 12 and produce a prompt sound indicating that the installation is complete. Finally, the pressing block 35, through the elastic thrust of the return spring 37 in the rotating slot 31, will firmly lock the abutting head 34 at the end of the rotating rod 33 into the fixed sleeve 12, making the process simple and quick.

[0032] The preferred embodiments of the above utility model are only used for helping to describe the utility model. The preferred embodiments do not describe all the details and do not limit the utility model to the specific implementation. Obviously, according to the content of the specification, many modifications and changes can be made. The specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the utility model, so that the person skilled in the art can well understand and utilize the utility model. The utility model is limited by the claims and the whole scope and equivalents thereof.
