Description

A wire harness fixing device and a vehicle Technical Field

[0001] This application relates to the field of vehicle component technology, and more specifically, to a wiring harness fixing device and a vehicle. Background Technology

[0002] New energy vehicle power supplies and electrical appliances need to be connected by wiring harnesses, which are generally composed of multiple cables. During the assembly process, the wiring harnesses need to be fixed by wiring harness fixing devices.

[0003] Existing wire harness fixing devices mostly adopt a "bracket + wire clamp" structure (see Figure 1) or a cable tie structure. The "bracket + wire clamp" structure is space-consuming, has poor versatility, and requires each cable to be individually inserted into the cable tray before fixing, resulting in low installation efficiency. Cable tie structures offer low reliability and aesthetic appeal. Summary of the Invention

[0004] In view of this, this application provides a wiring harness fixing device and vehicle, which aims to improve the problems of poor versatility, low installation efficiency, large space occupation, and low fixing reliability and aesthetics of the prior art.

[0005] In a first aspect, this application provides a wire harness fixing device, comprising:

[0006] The clamp body includes a "U"-shaped main body and mounting ear plates connected to both ends of the main body, each mounting ear plate having an assembly through hole; and

[0007] The flexible compensation structure is elastic and is fixedly connected to the inner side of the main body.

[0008] Preferably, the two assembly through holes are a round through hole and a strip hole, respectively.

[0009] Preferably, the flexible compensation structure is a rubber structure or a foam material structure.

[0010] Secondly, this application provides a vehicle including a frame and a wiring harness, wherein the wiring harness is mounted on the frame using the wiring harness fixing device provided in the first aspect of this application.

[0011] Compared with the prior art, the wiring harness fixing device and vehicle provided in this application achieve at least the following beneficial effects:

[0012] The clamp body ensures that the flexible compensation structure firmly secures the wire harness, maintaining a gapless connection and providing stable restraint without causing significant wear. Furthermore, the flexible compensation structure undergoes viscous deformation under stress, requiring greater force to overcome for relative sliding between the contact surfaces. The contact area between the flexible compensation structure and the wire harness remains consistently large, making it difficult for the wire harness to be pulled out, ensuring reliable and stable fixation. Moreover, fixing the wire harness with this device only requires threading the wire harness through the mounting space between the clamp body and the component being installed (e.g., the vehicle frame) and tightening the two bolts connecting to the mounting lugs. The installation process is simple, streamlined, and efficient. The mounting space can accommodate wire harnesses of various cross-sectional sizes, making this wire harness fixing device highly versatile. Compared to existing technologies, this wire harness eliminates the need for separation between multiple cables. The main body of the wire harness fixing device does not require a physical component (such as a hole wall) to separate the cables. This design results in a smaller size and less space requirements. Furthermore, the wire harness fixing device features a simple structure and high aesthetic appeal.

[0013] Of course, any product implementing this application need not specifically need to achieve all of the technical effects described above at the same time.

[0028] Referring to FIGS. 2 and 3, an embodiment of the present application provides a wire harness fixing device 10, including a clamp body 100 and a flexible compensation structure 200.

[0029] Among them, the clamp body 100 includes a main body portion 110 in a "U" shape and mounting ear plates 120 connected to both ends of the main body portion 110. Each mounting ear plate 120 is provided with an assembly through hole; the flexible compensation structure 200 has elasticity, and the flexible compensation structure 200 is fixedly connected to the inner side of the main body portion 110.

[0030] It should be understood that the wiring harness fixing device 10 provided in this embodiment can be used in the field of new energy electric vehicles, for example, to fix the wiring harness 30 connected to the electric drive axle. The wiring harness fixing device 10 can fix the wiring harness 30 to the vehicle frame 20. Of course, the wiring harness fixing device 10 can also be applied to wiring harnesses 30 in other fields, and this application does not make specific limitations in this regard.

[0031] Taking the embodiment shown in Figure 2 as an example, the installation of the wire harness fixing device 10 is described. During installation, the wire harness 30 is inserted into the main body 110. One mounting ear plate 120 is fixedly connected to the frame 20 by a first connecting bolt 41. The first connecting bolt 41 passes through the corresponding mounting through hole and the first connecting through hole of the frame 20, completing the pre-installation of the wire harness fixing device 10 and the frame 20. Then, the other mounting ear plate 120 is connected to the frame 20 by a second connecting bolt 42. The second connecting bolt 42 passes through the corresponding mounting through hole and the second connecting through hole of the frame 20. The first connecting bolt 41 and the second connecting bolt 42 are tightened to complete the connection and installation of the wire harness 30 and the frame 20. In the wiring harness fixing device 10, the flexible compensation structure 200 and the frame 20 form a closed installation space, in which the wiring harness 30 is accommodated and installed. The plate surface of the frame 20 and the flexible compensation structure 200 limit and constrain the wiring harness 30. The flexible compensation structure 200 is elastic and there is no gap between the flexible compensation structure 200 and the wiring harness 30. The mounting ear plate 120 of the clamp body 100 is fixedly connected to the frame 20 by connecting bolts. The main body 110 of the clamp body 100 ensures that the flexible compensation structure 200 presses and fixes the wiring harness 30.

[0032] The wiring harness fixing device 10 provided in this embodiment ensures that the flexible compensation structure 200 presses and fixes the wiring harness 30 tightly through the clamp body 100. The flexible compensation structure 200 maintains no gap with the wiring harness 30, forming a stable constraint, and the flexible compensation structure 200 will not cause significant wear to the wiring harness 30. In addition, the flexible compensation structure 200 undergoes viscous deformation under stress, and the relative sliding between the contact surfaces of the flexible compensation structure 200 and the wiring harness 30 requires overcoming a greater force. Furthermore, the contact surfaces between the flexible compensation structure 200 and the wiring harness 30 maintain surface contact with a large contact area. Therefore, the wiring harness 30 fixed by this wiring harness fixing device 10 is difficult to pull out, and the fixing of the wiring harness 30 is reliable and stable. Moreover, when fixing the wiring harness 30 with this wiring harness fixing device 10, it is only necessary to pass the wiring harness 30 into the installation space between the clamp body 100 and the installed component (e.g., the vehicle frame 20) and tighten the two connecting bolts connected to the mounting ear plate 120. The installation process is simple, has few procedures, and is highly efficient. The installation space can accommodate various cross-sectional specifications of wire harnesses 30, thus the wire harness fixing device 10 has high versatility. Compared with the prior art, there is no need to separate the multiple cables of the wire harness 30, and the main body 110 of the wire harness fixing device 10 does not need to be designed with a solid part (such as a hole wall) to separate the multiple cables. The wire harness fixing device 10 has a small design size and occupies little space. The wire harness fixing device 10 has a simple structure and high aesthetics.

[0033] In some embodiments, the two assembly through holes are a round through hole 121 and a strip hole 122, respectively.

[0034] In this embodiment, a mounting ear plate 120 has a strip-shaped hole 122. Taking the embodiment shown in Figure 2 as an example, firstly, the long axis of the strip-shaped hole 122 allows the second connecting bolt 42, which passes through it, to move slightly along its long axis within the hole. This can compensate for machining and assembly errors between the second connecting through hole on the frame 20 and the mounting ear plate 120, facilitating the assembly of the wire harness fixing device 10. Secondly, the wire harness fixing device 10 can be adapted to the second connecting through holes of different models of frame 20, reducing mold development costs and the variety of parts, and improving the versatility of the wire harness fixing device 10. Thirdly, when components undergo thermal deformation due to temperature changes, the strip-shaped hole 122 allows the second connecting bolt 42 to slide slightly along its long axis within the hole, releasing stress caused by deformation, improving the lifespan of the wire harness fixing device 10, the wire harness 30, and other related components, and preventing loosening. Fourthly, vibrations under operating conditions can cause relative micro-displacement between the wiring harness fixing device 10 and the frame 20. The clearance along the long axis of the strip hole 122 can serve as an elastic buffer space, reducing the rigid impact between the second connecting bolt 42 and the hole wall, extending the service life of fasteners (bolts, nuts, etc.), and reducing the risk of abnormal noise. Fifthly, it facilitates the alignment of the second connecting bolt 42 with the strip hole 122, making connection and assembly easier. Another mounting ear plate 120 has a through hole 121, which can limit the displacement of the clamp body 100, ensuring accurate positioning of the wiring harness fixing device 10. In addition, it can ensure installation strength and the reliability of the fixed connection. In summary, through the combined design of "through hole 121 + strip hole 122", the wiring harness fixing device 10 achieves a technical balance between positioning accuracy, installation efficiency, structural strength, and adaptability, and is especially suitable for scenarios with high requirements for reliability and assembly efficiency (such as fixing of high-voltage wiring harness 30 in new energy vehicles, layout of wiring harness 30 in engine compartment of fuel vehicles, etc.).

[0035] In some embodiments, the flexible compensation structure 200 is a rubber structure or a foam material structure.

[0036] In specific implementation, the flexible compensation structure 200 can be a structure made of any of the following materials: EPDM foam, silicone foam, or TPEE microporous foam.

[0037] Based on the same inventive concept, this application also provides a vehicle, including a frame 20 and a wiring harness 30, wherein the wiring harness 30 is mounted on the frame 20 using the wiring harness fixing device 10 provided in any of the above embodiments.
