Description

Technical Field

[0001] This utility model relates to a truck wiring harness protection device, belonging to the field of wiring harness protection technology. Background Technology

[0002] Wire harnesses are used in heavy-duty trucks and are the main connection components of the vehicle's internal circuitry. A wire harness is a component that is formed by crimping copper contact terminals with wires and cables, and then molding an insulator or adding a metal shell to the outside, and then bundling the wire harness together to form a circuit connection.

[0003] For example, utility model patent number 201510629409.4 discloses a light truck and its wiring harness clamp. The latter includes a mother plate, a first daughter plate rotatably mounted on the mother plate via a rotating shaft, and a constraint band forming a wiring harness accommodating space. It also includes a second daughter plate fixed to the mother plate, with one end of the constraint band fixed to the mother plate and the other end fixed to the second daughter plate. The first daughter plate has a plurality of first pressure teeth on one side facing the second daughter plate, and the second daughter plate has a plurality of second pressure teeth on one side facing the first daughter plate. When the first daughter plate rotates to its limit position near the mother plate, the first pressure teeth engage and fix with the second pressure teeth. In this way, the wiring harness is constrained by the clamping of the first and second daughter plates, avoiding contact between the constraint band and the pressure teeth, thereby preventing breakage of the constraint band, extending the service life of the clamp, and ensuring the safety of the wiring harness.

[0004] Current technology is not comprehensive and has the following drawbacks: 1. Wiring harnesses in general truck areas are wrapped with PVC tape, cloth tape, fleece tape, corrugated tubing, or PVC flexible tubing, and then simply arranged using common round-hole or oblong-hole cable ties and C-clips, or even simpler brackets and clips. However, this relatively simple wiring harness protection and arrangement is not very effective in resisting external pressure and poses a high safety risk. 2. It fails to protect the wiring harness from external impacts, and the wiring harness holes cannot effectively separate the charging cables to prevent them from tangling.

[0005] To solve one of the above problems, there is an urgent need for a truck wiring harness protection device. Utility Model Content

[0006] Based on the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to achieve the formation of a set of side guard plates by bending on both sides of the upper pressure plate, which can protect the wiring harness from external impact, and the wiring harness holes can effectively separate the charging cables and prevent the charging cables from getting tangled together. Therefore, a truck wiring harness protection device is provided.

[0007] The truck wiring harness protection device of this utility model includes an outer housing, and multiple sets of connecting seats are arranged along the length of the outer housing. Each connecting seat includes a base fixed to the vehicle body and a connecting bolt. The outer housing includes an upper pressure plate, and the connecting seat includes a lower elastic fixing member and an upper elastic fixing member that cooperate with each other.

The lower elastic fixing member and the upper elastic fixing member are clamped between the base and the upper pressure plate. Multiple sets of semi-circular slots B are provided on the upper elastic fixing member, and multiple sets of semi-circular slots A are provided on the lower elastic fixing member. Any set of semi-circular slots B and the corresponding upper baffle A form a wiring harness clamping hole.

[0008] The outer housing includes an upper pressure plate, and the two sides of the upper pressure plate are bent to form a set of side guards, which can protect the wire harness from external impacts, and the wire harness holes can effectively separate the charging wires and prevent the charging wires from getting tangled together.

[0009] Preferably, the base includes a connecting base plate fixedly connected to the vehicle body. Lower side baffles A and B are spaced apart on the outer surface of the connecting base plate. Both lower side baffles A and B are perpendicular to the connecting base plate and welded together. An inner support plate A is vertically welded to the inner side of the connecting base plate, and an inner support plate B is vertically welded to the inner side of the lower side baffles B. The inner support plates A and B are on the same plane, with a reserved gap between them. Connecting bolts pass through the baffles and the reserved gap sequentially. The two ends of the baffles are respectively attached to the surfaces of the inner support plates A and B. A lower elastic fixing member is located between the lower side baffles A and B and is supported by the inner support plates A and B.

[0010] Preferably, the connecting base plate is welded to the vehicle body.
