Description

Technical Field

[0001] The utility model belongs to the technical field of high-voltage main wiring harness protection structures, and more specifically, relates to a high-voltage main wiring harness protection structure for an automobile. Background Art

[0002] An automotive high-voltage main wiring harness is a cable system responsible for transmitting high-voltage current in electric or hybrid vehicles. This system is primarily used to connect battery packs, electric motors, and other high-voltage components to ensure power supply and management during operation. The design and maintenance of high-voltage main wiring harnesses are crucial to the safety and performance of electric vehicles. Among them, Chinese patent number: CN202322134069.0 discloses a protective structure for a high-voltage main wiring harness of an automobile, comprising an L-shaped base, on which a wiring harness protection assembly is arranged. The protection assembly comprises a positioning arc plate, a rotating arc plate, a first side plate, a second side plate and an L-shaped tube. The L-shaped tube is arranged between the positioning arc plates at both ends of the L-shaped base. The interior of one side of the positioning arc plate is rotatably connected to one side of the rotating arc plate through a rotating shaft. The other side of the rotating arc plate is integrally provided with a first side plate, which is connected and fixed to the second side plate arranged on the other side of the positioning arc plate by screws. By arranging the wiring harness protection assembly on the L-shaped base, better limited wrapping protection is achieved for the wiring harness that needs to be bent, preventing the wiring harness surface from being damaged or broken due to direct bending and twisting of the wiring harness, thereby increasing the service life of the wiring harness, reducing replacement costs, and improving the stability of the wiring harness.

[0003] Based on the above, the inventors found the following problems: the device in the above patent can better limit and wrap the wire harness that needs to be bent, thereby increasing the service life of the wire harness, but the diameter of the wire harness is different. The above device can only protect the wire harness of the appropriate diameter. When protecting the wire harness of different diameters, the entire device needs to be replaced, which is costly.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a protective structure for the high-voltage main wiring harness of an automobile is provided in order to achieve a purpose with greater practical value. Utility Model Content

A group of first thread grooves are opened on the surfaces of the first connecting plate and the second connecting plate, and first bolts are installed in the first thread grooves.

[0009] Furthermore, the mechanism for replacing the protective component is a slide groove provided on the surface of the L-shaped base, and a slider is installed on the surface of the first arc-shaped plate, and the slider matches the slide groove.

[0010] Furthermore, rubber pads are installed on the surfaces of the first curved plate and the second curved plate.

[0011] Furthermore, a second thread groove is provided in the first curved plate, rubber pad, slider and slide groove, and a second bolt is installed in the second thread groove. When the first curved plate contacts the L-shaped tube, the second thread groove on the surface of the first curved plate is aligned with the second thread groove in the slide groove.

[0012] Furthermore, a plurality of mounting parts are installed on the surface of the L-shaped base.

[0013] Furthermore, the protective component is made of plastic.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model cooperates with the first curved plate, the second curved plate, the hinge, the first connecting plate, the second connecting plate, the first threaded groove, the first bolt, the sliding groove and the slider.

With the above design, only the protective component needs to be replaced to protect wiring harnesses of different diameters, thereby reducing costs.

[0016] By using the second thread groove and the second bolt in conjunction with each other, when the first arc-shaped plate is fitted with the L-shaped tube, the second thread grooves are aligned, and then the second bolt is screwed into the second thread groove to complete the fixation of the protective assembly.
