Description

Technical Field

[0001] This invention belongs to the field of new energy vehicle technology, specifically a wiring harness structure for new energy vehicles. Background Technology

[0002] In new energy vehicles, high-voltage wiring harnesses are mainly used to transmit high-voltage electrical energy. The quality and safety of the high-voltage wiring harnesses directly affect the overall performance and safety of new energy vehicles.

[0003] For new energy vehicles, the DC bus (P / N) of the battery and the three-phase high-voltage wiring harness (W / U / V) of the motor are both arranged in a multi-line parallel manner. If a single-line clip is used, two or three clips need to be installed. Single-line clips are mostly fixed nearby, and then the high-voltage wire is fixed to the clip. After this fixing, the excess wiring harness will shake constantly as the car is moving. During the constant shaking, the outer protective sheath of the high-voltage wire will constantly collide and rub against the clip or surrounding objects, causing the protective sheath of the wire to wear out too quickly. In addition, high-voltage wires fixed in this way are inconvenient to replace or disassemble, the restraint effect is poor, and it is not aesthetically pleasing. At present, most models use single-line clips to fix the high-voltage wiring harness, which cannot meet the layout requirements.

[0004] In addition, existing wiring harnesses for new energy vehicles are usually connected by plug-in connections. When the road surface is uneven, the new energy vehicle will experience bumps, and the mounting head may become loose due to the vibration. Eventually, the mounting head may fall off the mounting base, affecting the normal power supply of the vehicle and thus posing a safety hazard to the new energy vehicle. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Example 1, by Figure 1 , Figure 2 and Figure 6 The present invention provides a wiring harness structure for new energy vehicles, comprising a wiring harness bracket 1, a wiring harness body 2, a wiring harness sleeve 3, a plurality of male connectors 4 and a plurality of female connectors 5.

[0038] Mounting plate 18 and screw 19 can be connected to new energy vehicles to improve stability. Flexible pad 20 can play a buffering role. Spring connecting post one 23 and spring connecting post two 24 can be connected to spring 16.

[0039] Example 3, based on Example 1, is... Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the male connector 4 is composed of an end plate 25, a male plug 26 and several limiting connecting plates 27. The male plug 26 is fixedly connected to one end of the end plate 25, and the limiting connecting plates 27 are fixedly connected to the top and bottom of the other end of the end plate 25. The female connector 5 is composed of an mounting plate 28, a female socket 29 and a limiting fastening mechanism 30. The mounting plate 28 is fixedly connected to the interior of the new energy vehicle, the female socket 29 is fixedly connected to one end of the mounting plate 28, and the limiting fastening mechanism 30 is connected to the outer surface of the female socket 29.

[0040] After the wiring harness is installed, the male plug 26 is inserted into the corresponding female socket 29. The limiting connection plate 27 and the limiting fastening mechanism 30 can achieve the limiting and reinforcement function, improve the stability of the connection, and prevent loosening or detachment.

[0041] The side of the female socket 29 is provided with a limiting groove 31 that matches the limiting and fastening mechanism 30. The limiting and fastening mechanism 30 is composed of a slider 32, several push springs 33, a first rotating shaft 34, a first gear 35, a first limiting frame 36, a second rotating shaft 37, a second gear 38, a second limiting frame 39, and a tension spring 40. The slider 32 is slidably connected inside the limiting groove 31. The push springs 33 are fixedly connected between the slider 32 and the female socket 29. The first rotating shaft 34 and the second rotating shaft 37 are both rotatably connected to one end of the slider 32. The first gear 35 and the first limiting frame 36 are both sleeved on the first rotating shaft 34 and fixedly connected to it. The second gear 38 and the second limiting frame 39 are both sleeved on the second rotating shaft 37. And fixedly connected to it, the tension spring 40 is connected between the first limiting frame 36 and the second limiting frame 39, and the other end of the first limiting frame 36 and the second limiting frame 39 are fixedly provided with a limiting rod 41 that matches the limiting connecting buckle plate 27. The first gear 35 and the second gear 38 are meshed and connected. One end of the side of the slider 32 is fixedly provided with a push plate 42, which has an arc-shaped structure. One side of the first limiting frame 36 and the second limiting frame 39 is fixedly provided with a semi-circular plate 43, and one side of the semi-circular plate 43 is fixedly provided with a push rod 44. The middle position of one side of the first limiting frame 36 is fixedly provided with a spring connecting column three 45, and the middle position of one side of the second limiting frame 39 is fixedly provided with a spring connecting column four 46.

[0042] When the limiting fastening mechanism 30 is connected to the limiting connecting plate 27, firstly, push the push rod 44 by hand. The push rod 44 drives the first limiting frame 36 or the second limiting frame 39 to rotate. Through the meshing of the first gear 35 and the second gear 38, the first limiting frame 36 and the second limiting frame 39 can rotate synchronously, causing the limiting rod 41 to move to the side of the male connector 4. Then, push the push plate 42. At this time, the push spring 33 is compressed, and the limiting rod 41 slides along the side of the male connector 4 until the limiting rod 41 slides into the inside of the limiting connecting plate 27. At this time, release the push plate 42. The push spring 33 drives the slider 32 to reset, causing the limiting rod 41 to move into the groove of the limiting connecting plate 27 to achieve limiting. To release the limiting, first push the push plate 42. After the limiting rod 41 moves out of the limiting connecting plate 27, push the push rod 44. The push rod 44 drives the first limiting frame 36 and the second limiting frame 39 to rotate in opposite directions.

[0043] In operation, a wire harness bracket consisting of a support base plate, an arc-shaped limiting sleeve, a limiting strap, a first limiting clamping mechanism, and a second limiting clamping mechanism can support and limit the wire harness and its sleeve. The first and second limiting clamping mechanisms, consisting of a support sleeve, a toothed clamping plate, a rotating support shaft, a limiting chuck, a handle, and a spring, can securely limit and tighten the wire harness sleeve, preventing movement or shaking. This reduces friction, avoids damage caused by friction, and extends its service life. It also facilitates the disassembly and replacement of the wire harness, improving operational convenience. Advantages: By setting up a male connector consisting of an end plate, a male plug, and several limiting connecting plates, and a female connector consisting of a mounting plate, a female socket, and a limiting fastening mechanism, power can be supplied through a plug-in connection. By setting up a limiting fastening mechanism consisting of a slider, several push springs, a first rotating shaft, a first gear, a first limiting frame, a second rotating shaft, a second gear, a second limiting frame, and a tension spring, the male and female connectors can be limited and reinforced to prevent them from loosening or falling off due to vibration, thereby improving the stability of power supply and thus improving the safety of new energy vehicles during operation.
