Automobile high-voltage wiring harness wire-passing protection structure

Abstract

The invention belongs to an automobile high-voltage wiring harness wire passing protection structure. The automobile high-voltage wiring harness wire passing protection structure comprises a rubber component, a waterproof sealing ring, wiring harness sleeves and an automobile body component; the upper face of an installation part of the rubber component is matched with the automobile body component; the waterproof sealing ring is arranged at the matched position of the rubber component and the automobile body component; and the plurality of wire harness sleeves are fixedly connected to the middle part of the rubber component. The automobile high-voltage wiring harness wire-passing protection structure is characterized in that a metal plate component is tightly attached to the lower surface of the installation part of the rubber component and is connected to theautomobile body component through a threaded fastener. With the automobile high-voltage wiring harness wire-passing protection structure of the invention adopted, the problems that the an automobile body is insufficient in strength, is inconvenient to assemble, and has increased reliability risk points can be solved, and the problems of air leakage and water leakage caused by untight sealing of the rubber component and the automobile body, the problem that the wiring harness sleeves are snapped and the problem the rubber component is disengaged from the automobile body can also be solved.

Description

technical field [0001] The invention relates to a high-voltage circuit of a new energy vehicle, in particular to a wire-passing protection structure for a high-voltage wire harness of an automobile. Background technique [0002] With the development of economy and society, global resources are constantly in short supply, and with the pressure of environmental protection and fuel consumption requirements, new energy vehicles are gradually popular in the market. Based on the pursuit of vehicle passability, stability and smoothness, four-wheel drive models have attracted more attention from the market. However, compared with the two-wheel drive model, the four-wheel drive adds a rear axle power drive system. Based on the space limitation of the current vehicle chassis, the rear axle motor controller is arranged in the trunk, and the rear axle motor is arranged on the chassis drive shaft outside the cab. The three-phase power wiring harness connecting the rear axle motor contr...
