Description

Technical Field

[0001] The present invention relates to the technical field of wire harness protection for new energy vehicles, and particularly to a combined protection device for new energy vehicle wire harnesses. Background Art

[0002] With the increasing requirements for the intelligence, householdization, and comfort of automobiles, the number of components and various controllers on automobiles is also increasing, which also means that there are more and more wire harnesses. Under the balance of multiple factors such as styling, function, and reliability, wiring in a narrow space will occur.

[0003] When wiring in a narrow space, conventional protection devices cannot be applied to the narrow space, resulting in wire harnesses in the narrow space usually not being provided with protection devices. Therefore, when wiring in a narrow space, the wire harnesses are not provided with protection devices, and during actual use, the wire harnesses directly contact and rub against the vehicle body, resulting in wear of the wire harnesses, affecting the service life of the vehicle, and even causing adverse consequences such as fire after a long time. Summary of the Invention

[0004] In view of the above deficiencies in the background art, the present invention provides a combined protection device for new energy vehicle wire harnesses, which solves the technical problem that the existing protection devices cannot be applied to narrow spaces, resulting in wire harnesses in narrow spaces usually not being provided with protection devices, and the wire harnesses directly contact and rub against the vehicle body during actual use.

[0005] The technical solution of the present invention is realized as follows: A combined protection device for new energy vehicle wire harnesses includes a plurality of protection units, and the plurality of protection units are detachably connected to form a protection device applicable to a narrow space; each protection unit includes a protection main body, and a partition for dividing the protection main body to form a plurality of wire harness channels is provided on the protection main body. The protection device of the present application includes a plurality of protection units, and a protection device applicable to a narrow space is formed by detachably connecting the plurality of protection units. By arranging the vehicle wire harnesses on the protection device of the present application, the situation that the wire harnesses in the narrow space directly contact and rub against the vehicle body is avoided, and the technical problem that the existing protection devices cannot be applied to narrow spaces, resulting in wire harnesses in narrow spaces usually not being provided with protection devices, and the wire harnesses directly contact and rub against the vehicle body during actual use is solved.

[0006] Preferably, the protection main bodies of two adjacent protection units are snap-connected. The protection device of the present application is formed by snap-connecting between the protection main bodies of two adjacent protection units. According to the thickness of the wire harness trunk, one or two or three or other numbers of protection units can be flexibly selected and combined together to form the protection device of the present application. In addition, the protection units can also be used in multiple places at the same time, realizing the sharing of the same protection unit at multiple positions, thereby reducing production costs.

[0007] Preferably, the protection main body is U-shaped. A clamping claw is provided on one side of the protection main body, and a clamping groove is provided on the opposite side of the protection main body. When two adjacent protection main bodies are connected, the clamping claw of one protection main body is clamped and matched with the clamping groove of the other protection main body; the cross section of the clamping claw is T-shaped, and the cross section of the clamping groove is also T-shaped. The protection main body is U-shaped to achieve the purpose of wrapping and protecting the automotive wire harness. When several protection units are combined to form the protection device of the present application, the connection between two adjacent protection main bodies is completed by inserting the clamping claw into the clamping groove and clamping.

[0008] Preferably, at least two of the clamping claws are provided on one side of the protection main body, and at least two of the clamping grooves are provided on the opposite side of the protection main body. By providing at least two of the clamping claws on the protection main body and correspondingly providing at least two of the clamping grooves on the opposite side of the protection main body, the connection firmness between two adjacent protection main bodies is effectively improved, and thus the strength of the combined protection device for the new energy vehicle wire harness of the present application is effectively ensured.

[0009] Preferably, a first protrusion is provided on the side wall of the clamping groove, and a second protrusion is provided on the clamping claw. When two adjacent protection main bodies are connected, the clamping claw of one protection main body is inserted and matched with the clamping groove of the other protection main body, and the first protrusion and the second protrusion are in a blocking fit. The first protrusion and the second protrusion are arranged on the path of the clamping claw inserted into the clamping groove. After the clamping claw is completely inserted into the clamping groove, the first protrusion and the second protrusion are in a blocking fit to complete the clamping of two adjacent protection main bodies.

[0010] Preferably, a limiting groove is provided on the clamping claw, and the first protrusion is adapted to the limiting groove, and the second protrusion is located in the limiting groove. During the process of the clamping claw being inserted into the clamping groove, the first protrusion always moves along the limiting groove, restricting the movement path of the first protrusion, so that after the clamping claw is completely inserted into the clamping groove, the first protrusion will necessarily be in a blocking fit with the second protrusion. The setting of the limiting groove is to avoid the dislocation of the first protrusion and the second protrusion and the situation where the first protrusion and the second protrusion are not in a blocking fit during the process of the clamping claw being inserted into the clamping groove.

The partition plates are provided to divide the space on the protection main body into wire harness channels, separating adjacent automotive wire harnesses and avoiding friction between wire harnesses. By providing at least two of the partition plates on the protection main body, the space is divided into at least three wire harness channels by at least two of the partition plates. Specifically, the number of the partition plates provided on the protection main body can be set according to the wire harness channels actually required by the automotive wire harness.

[0012] And when the automotive wiring harness is routed, several branch wiring harnesses are usually combined into a larger-sized wiring harness assembly. After using the protection device of the present application, the larger-sized wiring harness assembly can be divided into several smaller-sized wiring harness assemblies, and the smaller-sized wiring harness assemblies are respectively placed in the wiring harness channels formed by the partition and the protection main body, thereby reducing the size of the wiring harness assembly, facilitating the routing of the automotive wiring harness in a narrow space, and solving the problem that the larger-sized wiring harness assembly cannot pass through a narrow space.

[0013] Preferably, the protection main body is provided with tie-down holes for tie-down straps to pass through. The tie-down holes are provided for threading tie-down straps on the one hand, using the tie-down straps to bind the wiring harness and tying the wiring harness to the protection main body; on the other hand, the tie-down holes also serve as drain holes. Two of the tie-down holes are arranged oppositely on the protection main body. One end of the tie-down strap is inserted through one tie-down hole on the protection main body and extends out through the other tie-down hole on the protection main body, and then the two ends of the tie-down strap are locked to complete the binding of the tie-down strap to the wiring harness. The tie-down strap is of an existing tie-down strap structure, that is, one end of the tie-down strap is a sharp corner, and the other end is a square lock. When the sharp-corner end of the tie-down strap is inserted through one tie-down hole on the protection main body and extends out through the other tie-down hole on the protection main body, after the sharp-corner end of the tie-down strap passes through the square lock, the locking of the tie-down strap is completed.

[0014] Preferably, the partition is provided with a fixing groove, and the fixing groove is arranged parallel to the tie-down holes. The fixing groove is located between the two tie-down holes. The fixing groove is provided on the partition and is arranged parallel to the tie-down holes. Such an arrangement makes it possible that when the sharp-corner end of the tie-down strap is inserted through one tie-down hole on the protection main body, it first passes through the fixing groove and then extends out through the other tie-down hole on the protection main body. After the sharp-corner end of the tie-down strap passes through the square lock, the locking of the tie-down strap is completed. The setting of the fixing groove effectively ensures the stability of the position of the tie-down strap after the tie-down strap is locked.

[0015] Preferably, the protection main body is provided with a connecting groove, and the connecting groove is located between two adjacent card slots; the connecting groove has the same structure as the card slot.
