Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, specifically to a high-voltage wiring harness protection device for new energy vehicles. Background Technology

[0002] With the rapid development of the global automotive industry, automakers are facing increasingly stringent environmental regulations and high consumer demands for new energy vehicles. Lightweight design, as a crucial means to improve vehicle efficiency and reduce carbon emissions, has become one of the important research directions in the automotive industry.

[0003] The following problems exist in the current high-voltage wiring harness layout of new energy vehicle chassis: The specific value of the ground clearance of the high-voltage wiring harness varies from vehicle model to vehicle model. It is usually required that it does not protrude from the lowest point of the chassis, and the ground clearance is generally low. However, when customers drive in harsh actual conditions, it is easy to be scratched by road bumps and impacted by flying stones. The traditional corrugated pipe is made of polyvinyl chloride (PVC) with a spiral corrugated structure, which has poor impact resistance and is easily broken. The repair cost of high-voltage wire damage is expensive and the safety risk is high. In order to avoid damage to the wiring harness, the wiring harness is often detoured and raised, thereby increasing the length of the wiring harness, which leads to an increase in cost and vehicle weight.

[0004] The existing high-voltage wiring harness is fixed with metal brackets, while the wiring harness protection is mostly made of stamped aluminum alloy plates, which are heavy and prone to electrolytic corrosion. Attention should be paid to the design of drainage holes to avoid water accumulation, and the impact of stones can also cause vibration and abnormal noise. Utility Model Content

[0005] This utility model addresses the problem of high-voltage wiring harnesses in new energy vehicles being easily damaged by stones and scratches due to their low ground clearance, posing safety risks and high maintenance costs. A protection device for high-voltage wiring harnesses in new energy vehicles is proposed, with the specific technical solution as follows:

[0006] A high-voltage wiring harness protection device for new energy vehicles is disclosed. The device is a U-shaped wire protection groove. The front and rear ends of the opening of the U-shaped wire protection groove are provided with outwardly turned mounting parts. Mounting holes are provided on the mounting parts. Multiple cable tie mounting holes are provided in the U-shaped wire protection groove. The high-voltage wiring harness is fixed in the U-shaped wire protection groove with wire harness fixing cable ties.

[0007] Furthermore, the height difference between the two mounting parts is 2-5mm, which makes the U-shaped cable tray tilted at a certain angle after installation, facilitating drainage.

[0008] Furthermore, the U-shaped cable guide groove is an injection molded part.

[0009] Furthermore, the cable tie mounting holes are arranged in pairs and evenly distributed along the U-shaped cable protection groove.

[0010] Furthermore, a copper nut is pre-embedded in the mounting hole.

[0011] Furthermore, the length of the U-shaped cable tray is adjusted according to the actual wiring route of the cable harness.

[0012] This utility model features a U-shaped protective structure that encloses the high-voltage line. The high-voltage line harness and the protective channel are integrated as a single unit. The high-voltage line harness and the protective channel are connected and fixed with cable ties, eliminating the need for a harness bracket and facilitating installation and disassembly. It also solves the risk problem of low ground clearance. By finding the shortest layout path, the length of the harness can be greatly shortened, reducing costs and achieving lightweight design.
