[0032] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0033] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0034] This application provides a vehicle. (Reference) Figure 1 The vehicle includes a frame 1, a stabilizer bar 2, and a wiring harness assembly 3. The stabilizer bar 2 is connected to the frame 1. A wiring space 5 is provided between the stabilizer bar 2 and the frame 1 in the vertical direction. The wiring harness assembly 3 passes through the wiring space 5 in the radial direction of the stabilizer bar 2, thereby meeting the vehicle's electrical connection requirements. In the vehicle of this application, the wiring space 5 is relatively small in the vertical direction, making it difficult to secure the wiring harness by wrapping it around the stabilizer bar 2.

[0035] The wiring space 5 includes a first subspace 51 and a second subspace 52. In the height direction, the size of the first subspace 51 is smaller than the size of the second subspace 52. The wiring harness assembly 3 includes a first wiring harness 31 and a second wiring harness 32. The first wiring harness 31 is disposed in the first subspace 51. The second wiring harness 32 is disposed in the second subspace 52 and connected to the frame 1. Thus, a larger diameter wiring harness can serve as the second wiring harness 32, passing through the larger second subspace 52 and the wiring space 5; a smaller diameter wiring harness can serve as the first wiring harness 31, passing through the smaller first subspace 51 and the wiring space 5.

[0036] For example, the first wire harness 31 can be a power wire, ground wire, or other wire harness. These wire harnesses have a small diameter. For example, the diameter of a power wire is less than 7 mm, and the diameter of a ground wire is less than 4 mm. Therefore, these wire harnesses can be routed in the smaller first subspace 51. The second wire harness 32 can be, for example, a signal wire or other wire harness. These wire harnesses have a larger diameter. For example, the diameter of a signal wire is greater than 7.5 mm. If the second wire harness 32 is to be routed through the routing space 5, the routing space 5 needs to have more space in the vertical direction. In this case, the space in the vertical direction of the first subspace 51 may not be sufficient to meet the routing requirements of the second wire harness 32. Therefore, these wire harnesses can be routed in the second subspace 52, which has more space in the vertical direction. Of course, this application does not limit the specific type and size of the first wire harness 31 and the second wire harness 32.

[0037] The first wire harness 31 may include multiple wires. All multiple first wire harnesses 31 pass through the wiring space 5 from the first subspace 51. In order to fix the first wire harness 31, this application also provides a wire harness bracket 4.

[0038] Combination Figure 2 and Figure 3 The wire harness bracket 4 includes a wire harness fixing portion 41 and a connecting portion 42. The wire harness fixing portion 41 includes a main fixing portion 411, a first side fixing portion 412, and a second side fixing portion 413. The first side fixing portion 412 and the second side fixing portion 413 are disposed at opposite ends of the main fixing portion 411. The main fixing portion 411, the first side fixing portion 412, and the second side fixing portion 413 enclose a wire harness accommodating space 414 forming the wire harness fixing portion 41. The connecting portion 42 is connected to the end of the first side fixing portion 412 away from the main fixing portion 411. The connecting portion 42 of the wire harness bracket 4 is connected to the vehicle frame 1 so that the vehicle frame 1 encloses the wire harness accommodating space 414. A plurality of first wire harnesses 31 are disposed in the wire harness accommodating space 414.

[0039] The cooperation between the main fixing part 411 and the frame 1 restricts the displacement of the first wiring harness 31 in the height direction. The cooperation between the first side fixing part 412 and the second side fixing part 413 restricts the displacement of the first wiring harness 31 on both sides of the main fixing part 411. With this arrangement, one wiring harness bracket 4 can be used to fix multiple first wiring harnesses 31, which helps to reduce the number of fixing parts required for the vehicle. At the same time, the cooperation between the wiring harness bracket 4 and the frame 1 can enclose the first wiring harness 31 in the wiring harness accommodating space 414, thereby improving the fixing stability of the first wiring harness 31. In this way, the stabilizer bar 2 and the frame 1 can also meet the wiring requirements in the relatively small first subspace 51. Fixing the first wiring harness 31 with the wiring harness bracket 4 without wrapping it around the stabilizer bar 2 is beneficial for meeting the wiring harness arrangement requirements of the vehicle in a limited space. Furthermore, the wiring harness bracket 4 can also fix the first wiring harness 31 during the bumps and vibrations generated during vehicle operation, avoiding the displacement of the first wiring harness 31 and the resulting instability of the electrical connection.

[0040] The second wiring harness 32 can be secured to the frame 1 using clips 6. For example... Figure 2 As shown, the clip 6 is fitted around the outer periphery of the second wiring harness 32 and can then engage with the corresponding hole structure on the frame 1 to secure the second wiring harness 32. The clip 6 is a universal component. Therefore, this arrangement reduces the number of parts that need to be designed and manufactured in-house, which helps reduce design costs, production costs, and subsequent maintenance costs. Of course, the vehicle can also use a special bracket to secure the second wiring harness 32, or use a hook structure designed on the frame 1 to secure the second wiring harness 32. This application does not limit this.

[0041] In some optional embodiments, the arrangement direction of the plurality of first wiring harnesses 31 is parallel to that of the vehicle frame 1. In other words, the plurality of first wiring harnesses 31 are arranged side by side on the surface of the vehicle frame 1. This arrangement helps to reduce the space occupied by the first wiring harnesses 31 in the height direction, thereby reducing the space requirements of the first subspace 51 in the height direction when the first wiring harnesses 31 are being routed. For example, the first wiring harnesses 31 are power lines and ground lines. Taking a power line diameter of 6.8 mm and a ground line diameter of 3.7 mm as an example, the dimension of the first subspace 51 in the height direction only needs to be larger than the diameter of the power line to meet the routing requirements of the first wiring harnesses 31.

[0042] To further improve the fixing strength of the first wire harness 31, in some optional embodiments, the wire harness assembly 3 further includes a covering member 33. The covering member 33 fixes multiple first wire harnesses 31. The covering member 33 is disposed in the wire harness receiving space 414 and is interference-fitted with the wire harness bracket 4. The covering member 33 covers multiple first wire harnesses 31 and is disposed in the wire harness receiving space 414. Therefore, the covering member 33 can fill the empty space between the first wire harnesses 31 and the wire harness fixing part 41, thereby preventing the first wire harnesses 31 from moving back and forth in the wire harness receiving space 414 due to bumps and vibrations during vehicle operation, which could lead to displacement of the first wire harnesses 31 or even detachment of the wire harness bracket 4.

[0043] The interference fit between the cover 33 and the wire harness bracket 4 should be understood as an interference fit between the cover 33 and the wire harness bracket 4 at the contact position. For example, the dimension of the cover 33 in the height direction is slightly larger than the dimension of the accommodating space in the height direction. Then, when the wire harness bracket 4 is connected to the frame 1, the main fixing part 411 will apply pressure to the cover 33 in the height direction pointing towards the frame 1. This arrangement can further ensure the fixation of the relative position of the cover 33 and the wire harness bracket 4, thereby ensuring the fixing effect of the first wire harness 31.

[0044] like Figure 2 As shown, the main fixing part 411 may include a limiting hole 417 communicating with the wire harness accommodating space 414. The covering part 33 includes a limiting protrusion 332. The limiting protrusion 332 is disposed in the limiting hole 417. The cooperation between the limiting hole 417 and the limiting protrusion 332 can further prevent relative displacement between the wire harness bracket 4 and the covering part 33. During assembly, the cooperation between the limiting hole 417 and the limiting protrusion 332 can also guide the assembly, thereby improving assembly efficiency.

[0045] The material of the covering 33 can be, for example, rubber or plastic. These materials have a certain degree of elasticity, thus allowing for some deformation when it is interference-fitted with the wire harness bracket 4, preventing damage to components caused by a rigid fit. The covering 33 can be directly injection molded onto the outer circumference of the first wire harness 31, thereby improving the covering effect of the covering 33. In other embodiments, the covering 33 can also be pre-formed, and then the first wire harness 31 is assembled by passing the holes in the covering 33.

[0046] In some optional embodiments, the hardness of the cover 33 is greater than or equal to 75A and less than or equal to 95A. For example, the hardness of the cover 33 can be 75A, 76A, 77A, 78A, 79A, 80A, 81A, 82A, 83A, 84A, 85A, 86A, 87A, 88A, 89A, 90A, 91A, 92A, 93A, 94A, or 95A. The cover 33 within this range has a certain degree of hardness, thereby fixing the first wiring harness 31 in place when the frame 1 vibrates, causing the first wiring harness 31 to vibrate synchronously. Furthermore, during the vehicle's wiring assembly process, because the cover 33 has a certain degree of hardness, multiple first wiring harnesses 31 can maintain the desired shape, preventing the first wiring harnesses 31 from moving towards the stabilizer bar 2, thus reducing the distance between the first wiring harness 31 and the stabilizer bar 2 and increasing the difficulty of wiring arrangement.

[0047] refer to Figure 3 In some optional embodiments, the second side fixing portion 413 is configured as an arc. The center of the arc of the arc-shaped second side fixing portion 413 is located on the side of the second side fixing portion 413 facing the wire harness accommodating space 414. In other words, the middle position of the second side fixing portion 413 is further away from the first side fixing portion 412 than its two ends. Since the wire harness is usually a circular wire harness, configuring the second side fixing portion 413 as an arc can improve the surface fit between the wire harness fixing portion 41 and the first wire harness 31. In this way, the gap between the first wire harness 31 and the wall surface of the second side fixing portion 413 facing the wire harness accommodating space 414 can be reduced, which is beneficial to improving the fixing effect of the first wire harness 31.

[0048] Similarly, the first side fixing portion 412 can also be configured as an integral arc shape to cooperate with the first wire harness 31. In some optional embodiments, the first side fixing portion 412 includes a first arc-shaped unit 412a and a second arc-shaped unit 412b. One end of the first arc-shaped unit 412a is connected to the main fixing portion 411, and the other end is connected to the second arc-shaped unit 412b. The end of the second arc-shaped unit 412b away from the first arc-shaped unit 412a is connected to the connecting portion 42. The arc centers of the first arc-shaped unit 412a and the second arc-shaped unit 412b are located on the side of the first side fixing portion 412 facing the wire harness accommodating space 414. The arrangement of multiple arc-shaped units makes the first side fixing portion 412 form a stepped shape. In the height direction, the distance between the end of the first arc-shaped unit 412a away from the connecting portion 42 and the frame 1 is greater than the distance between the end of the second arc-shaped unit 412b away from the connecting portion 42 and the frame 1. Therefore, the first arc-shaped unit 412a can be used to fit with the first wire harness 31 with a larger diameter, while the second arc-shaped unit 412b can be used to fit with the first wire harness 31 with a smaller diameter.

[0049] by Figure 3Taking the illustrated embodiment as an example, the first wire harness 31 of the wire harness assembly 3 can consist of three power wires and one ground wire. The diameter of the power wires is larger than the diameter of the ground wire. Therefore, the ground wire is in contact with the second arc-shaped unit 412b, and the power wires adjacent to the ground wire cooperate with the first arc-shaped unit 412a. In this way, both the power wires and the ground wire can be fixed in the wire harness accommodating space 414.

[0050] With this configuration, the wire harness fixing part 41 can achieve the fitting and fixing of first wire harnesses 31 of different diameters, avoiding the shaking of the smaller diameter first wire harness 31 in the wire harness accommodating space 414, which helps to improve the fixing stability of the first wire harness 31 by the wire harness bracket 4.

[0051] It should be noted that this application does not specifically limit the number or size of the first wire harness 31. The first wire harness 31 may consist of only two, three, or more, such as five. Furthermore, the diameter of the first wire harness 31 may also be the same. The embodiments shown in the accompanying drawings should be considered exemplary rather than limiting.

[0052] In some optional embodiments, the wiring harness fixing portion 41 includes a first end face 415 and a second end face 416. At least a portion of the main fixing portion 411 extends in a curved direction, so that the first end face 415 and the second end face 416 form an angle. The first end face 415 and the second end face 416 are closer to the side of the first side fixing portion 412. With this arrangement, the wiring harness bracket 4 can, to a certain extent, guide the first wiring harness 31 to change its routing direction and provide fixation when the first wiring harness 31 changes position, thus eliminating the need for assembly personnel to adjust the direction of the first wiring harness 31 back and forth during vehicle assembly. Furthermore, since the first wiring harness 31 needs to pass through the relatively small first subspace 51, this arrangement further ensures that the first wiring harness 31 extends in the desired routing direction and maintains the spacing between the first wiring harness 31 and the stabilizer bar 2.

[0053] like Figure 1 As shown, in Figure 1 In the shown view, the routing position of the first wiring harness 31 is located at the edge of one of the height changes of the frame 1, and the routing direction is away from the edge. At this time, the main fixing part 411 is set to be curved, and the connecting part 42 is located on the inside of the curve. In this way, the connecting part 42 can be directly connected to the surface of the frame 1 in the first subspace 51 without the need to set an additional fixing structure on the outside of the curve to fix the connecting part 42. It can be seen that this arrangement simplifies the structure of the frame 1 and facilitates the connection of the connecting part 42.

[0054] Back Figure 2 and Figure 3In some optional embodiments, the portion of the main fixing portion 411 near the first end face 415 extends in a straight line. A second side fixing portion 413 is disposed on one side of the straight-extending main fixing portion 411. In other words, the second side fixing portion 413 is only disposed on the straight-extending portion of the main fixing portion 411, and not on the curved-extending portion. Since the second side fixing portion 413 is disposed on the outer side of the curve, if the second side fixing portion 413 were disposed at one end of the curved extension, it could result in increased material usage, increased processing difficulty, and decreased yield.

[0055] In this embodiment, the steering and guiding function of the first wire harness 31 is achieved by the first side fixing part 412. That is, the assembler applies force to the first wire harness 31 to make the first wire harness 31 abut against the inner wall of the first side fixing part 412 toward the wire harness accommodating space 414, thereby changing the routing direction of the first wire harness 31 at the position of the wire harness bracket 4.

[0056] In embodiments where the wire harness assembly 3 includes a covering member 33, the covering member 33 can cover the position where the first wire harness 31 turns. The cooperation between the covering member 33 and the second-side fixing portion 413 ensures the first wire harness 31 is fixed in its turning direction while maintaining the yield rate of the wire harness bracket 4. In this embodiment, the covering member 33 may include a deformation groove 331. The deformation groove 331 is disposed on the outer surface of the covering member 33 and communicates with the internal space accommodating the first wire harness 31. The deformation groove 331 allows the covering member 33 to bend in accordance with the change in the orientation of the first wire harness 31 and effectively avoids stress concentration problems.

[0057] In some alternative embodiments, such as Figure 2 As shown, the first wire harness 31 and the second wire harness 32 are connected at a position away from the wiring space 5. In other words, the wire harness assembly 3 is originally wrapped as a bundle of wires. When it approaches the wiring space 5, the wrapping of the wire harness assembly 3 is unwrapped, separating into the first wire harness 31 and the second wire harness 32, which are then routed through the first subspace 51 and the second subspace 52, respectively. After the first wire harness 31 and the second wire harness 32 leave the first subspace 51 and the second subspace 52, the wire harness assembly 3 is wrapped again as a bundle of wires. This arrangement avoids the messiness caused by the dispersed first wire harness 31 and the second wire harness 32, and helps to reduce the wiring difficulty of the wire harness assembly 3.

[0058] Under the action of the bending and extending main fixing part 411, even if the first wire harness 31 has an undesirable routing trend under the action of the wire harness assembly 3 which is originally an integral part, the wire harness bracket 4 can change the routing direction of the first wire harness 31 to the desired routing direction, thereby reducing the difficulty of wiring.

[0059] The connection between the connecting part 42 and the frame 1 can be achieved through welding, fastener connection, or other methods. In some optional embodiments, the connecting part 42 further includes a first fixing part 421 and a second fixing part 422. The first fixing part 421 is parallel to the main fixing part 411. The second fixing part 422 is disposed at the edge of the first fixing part 421, and its extension direction is different from that of the first fixing part 421. Since the first fixing part 421 is parallel to the main fixing part 411, the first fixing part 421 can fit snugly against the frame 1, increasing the contact area between the first fixing part 421 and the frame 1, thereby improving the connection stability. Since the extension direction of the second fixing part 422 is different from that of the first fixing part 421, after the connecting part 42 and the frame 1 are connected, the second fixing part 422 can prevent the first fixing part 421 from rotating parallel to the surface of the frame 1, thereby further preventing changes in the relative position between the connecting part 42 and the frame 1.

[0060] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
