Description

Technical Field

[0001] The utility model belongs to the field of automobile high-voltage wire harnesses, and specifically relates to a high-voltage wire harness protection bracket for commercial vehicles. Background Art

[0002] At present, the high-voltage wiring harness is fixed on the high-voltage junction box of the motor of new energy commercial vehicles. Since the inlet end of the motor high-voltage junction box is waterproofed with a sealing ring, the inlet end of the motor high-voltage junction box is generally directly exposed to the air. However, if the motor high-voltage wiring harness is used for too long, the use environment is harsh, or the sealing ring fails due to improper assembly, it is easy to cause water to enter the motor high-voltage junction box, thereby causing damage to the motor high-voltage wiring harness and vehicle failure. In addition, the operating environment of commercial vehicles is relatively harsh, and it is inevitable to encounter sand and stone splashing during operation, which can easily cause impact damage to the high-voltage wiring harness.

[0003] To solve the above problems, the patent document with publication number CN210174790U discloses a protective pad for preventing damage to the high-voltage wiring harness, including a fixing plate and a protective cover. The fixing plate is used to be fixedly connected to the vehicle body sheet metal. The protective cover includes a main body and an opening. The main body and the fixing plate are connected to each other. The main body is used to be sleeved between the vehicle body sheet metal and the high-voltage wiring harness to protect the high-voltage wiring harness. The opening is opened in the main body and is used to pass through the high-voltage wiring harness buckle to fix the high-voltage wiring harness to the vehicle body sheet metal. However, it cannot solve the above problems. Utility Model Content
