Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to an integrated fixing device for aluminum busbar and low-voltage wiring harness and a vehicle. Background Technology

[0002] As vehicle configurations increase, low-voltage loads grow, requiring larger diameter copper wires for battery power lines to compensate for voltage drops. This leads to increased wiring harness volume and installation difficulties in the sill area. Replacing copper wires with aluminum busbars offers advantages such as reduced Z-axis space occupation, lower cost, and lighter weight. Existing technologies typically place aluminum busbars in the central tunnel area, but this poses a risk of trampling during final assembly. When placing aluminum busbars in the sill area, the coordinated fixing of the aluminum busbars and low-voltage wiring harnesses needs to be addressed: separate fixing requires additional Y-axis space and increases the number of openings, resulting in decreased NVH performance and increased risk of water ingress. Summary of the Invention

[0003] This utility model provides an integrated fixing device and vehicle for aluminum busbar and low-voltage wiring harness, which effectively solves the problems of insufficient space, decreased NVH performance and increased risk of water ingress when aluminum busbar and low-voltage wiring harness coexist in the threshold area.

[0004] The technical solution of this utility model is as follows:

[0005] On the one hand, this application provides an integrated fixing device for aluminum busbar and low-voltage wire harness, including: an integrated low-voltage wire harness fixing structure and an aluminum busbar fixing structure;

[0006] The low-voltage wire harness fixing structure has a first mounting cavity for the low-voltage wire harness to pass through.

[0007] The aluminum busbar fixing structure has a second mounting cavity for the aluminum busbar to pass through.

[0008] Preferably, the aluminum busbar fixing structure is located below the low-voltage wire harness fixing structure.

[0009] Preferably, the integrated fixing device for the aluminum busbar and low-voltage wiring harness further includes a first buckle for connecting to the vehicle body, the first buckle being connected to the aluminum busbar fixing structure.

[0010] Preferably, the aluminum busbar fixing structure is located on the right side of the low-voltage wire harness fixing structure.

[0011] Preferably, the aluminum busbar fixing structure and the low-voltage wire harness fixing structure are made of PA66 and GF35 composite material.

[0012] Preferably, the low-voltage wire harness fixing structure includes: a first fixing member and a second fixing member formed on the aluminum busbar fixing structure;

[0013] The first fixing member is provided with a plurality of first slots, and the second fixing member is provided with a first hook for engaging with one of the first slots.

[0014] Preferably, the aluminum busbar fixing structure includes:

[0015] An aluminum busbar fixing structure body with the second mounting cavity formed inside;

[0016] The third fastener is connected to the aluminum busbar fixing structure body and can either close or expose the second mounting cavity.

[0017] Preferably, one end of the third fixing member is fixed to one end of the aluminum busbar fixing structure body;

[0018] A second slot is formed on the other end of the aluminum strip fixing structure body, and a second hook is provided on the other end of the third fixing member to engage with the second slot.

[0019] On the other hand, this application also provides a vehicle including the above-mentioned integrated fixing device for aluminum busbar and low-voltage wiring harness, further including: low-voltage wiring harness and aluminum busbar, the low-voltage wiring harness passing through the second mounting cavity and fixed by the low-voltage wiring harness fixing structure, and the aluminum busbar passing through the first mounting cavity and fixed by the aluminum busbar fixing structure.

[0020] Preferably, the low-voltage wiring harness is also fixed to the vehicle body by a second clip.

[0021] The beneficial effects of this utility model are as follows:

[0022] By integrating the low-voltage wiring harness fixing structure and the aluminum busbar fixing structure into the same device, the problem of additional vehicle space occupation when fixing them separately is avoided, and the space utilization rate of the vehicle is significantly improved.

[0023] By adopting a layout with the aluminum busbar on the right and the wiring harness on the left, the horizontal space in the threshold area is fully utilized, avoiding the insufficient Z-axis space problem caused by the vertical stacking of the aluminum busbar and wiring harness in traditional layouts. This layout is particularly suitable for scenarios where the threshold area has limited space and low-voltage wiring harnesses and aluminum busbars need to be arranged simultaneously, optimizing the arrangement path of the wiring harness and aluminum busbars and reducing interference with other components.

[0024] The low-voltage wiring harness and aluminum busbar are secured by snapping together the first and second fasteners, as well as the aluminum busbar fixing structure body and the third fastener. This eliminates the need for additional openings in the door sill area. This design reduces the number of openings, mitigating the NVH performance degradation and water ingress risk caused by excessive openings. It also simplifies the production process and improves efficiency. By reducing the number of openings in the door sill area, the noise and vibration transmission paths caused by excessive openings are reduced, significantly improving the overall NVH performance of the vehicle. Reducing the number of openings also directly reduces the risk of water ingress caused by excessive openings. Attached Figure Description

[0030] To facilitate understanding by those skilled in the art, the present utility model patent is further described below with reference to the accompanying drawings. While the description is quite detailed, it should not be construed as limiting the scope of the present utility model patent. Obvious variations and substitutions of the following examples are all within the protection scope of this patent.

[0031] like Figure 1-5 As shown, this application embodiment provides an integrated fixing device for aluminum busbar and low-voltage wire harness, including an integrated low-voltage wire harness fixing structure 1 and an aluminum busbar fixing structure 2. The low-voltage wire harness fixing structure 1 has a first mounting cavity 101 for the low-voltage wire harness 4 to pass through, and the aluminum busbar fixing structure 2 has a second mounting cavity 201 for the aluminum busbar 5 to pass through.

[0032] In one embodiment, reference is made to... Figure 2The aluminum busbar fixing structure 2 is located below the low-voltage wiring harness fixing structure 1, that is, the aluminum busbar 5 is set below the low-voltage wiring harness 4. This layout, with the aluminum busbar 5 positioned below and the low-voltage wiring harness 4 positioned above, fully utilizes the vertical space in the sill area, avoiding the Y-axis space occupation problem caused by the parallel arrangement of the aluminum busbar 5 and the low-voltage wiring harness in traditional layouts. This effectively solves the problem of insufficient space in the sill area, significantly improves the utilization rate of interior space, and makes the arrangement of the wiring harness and aluminum busbar more compact.

[0033] In another embodiment, refer to Figure 3 Alternatively, the aluminum busbar fixing structure 2 can be located to the right of the low-voltage wiring harness fixing structure 1, that is, the aluminum busbar 5 is set to the right of the low-voltage wiring harness 4. By adopting the layout of placing the aluminum busbar 5 on the right and the low-voltage wiring harness 4 on the left, the horizontal space of the threshold area is fully utilized, avoiding the problem of insufficient Z-direction space caused by the vertical stacking of the aluminum busbar 5 and the low-voltage wiring harness 4 in the traditional layout. This significantly improves the space utilization rate and makes the arrangement of the low-voltage wiring harness 4 and the aluminum busbar 5 more reasonable.

[0034] Reference Figure 1 and Figure 4 The low-voltage wiring harness fixing structure 1 in this embodiment includes a first fixing member 11 and a second fixing member 12. The first fixing member 11 is provided with a plurality of first slots 111, and the second fixing member 12 is provided with a first hook 121 for engaging with one of the first slots 111. Through the engaging cooperation of the first slots 111 and the first hook 121, the low-voltage wiring harness 4 can be firmly fixed within the first mounting cavity 101, ensuring that it will not loosen due to vibration during vehicle operation. At the same time, this engaging structure reduces the need for additional openings required in traditional fixing methods, lowering the risk of NVH performance degradation and water ingress caused by excessive openings.

[0035] Reference Figure 1 and Figure 5 In this embodiment, the aluminum busbar fixing structure 2 includes an aluminum busbar fixing structure body 21 and a third fixing member 22. A second mounting cavity 201 is formed inside the aluminum busbar fixing structure body 21. The third fixing member 22 is connected to the aluminum busbar fixing structure body 21 and can either close or expose the second mounting cavity 201. One end of the third fixing member 22 is fixed to one end of the aluminum busbar fixing structure body 21, and a second slot 211 is formed on the other end of the aluminum busbar fixing structure body 21. The other end of the third fixing member 22 is provided with a second hook 221 that engages with the second slot 211. Through the engaging cooperation of the second slot 211 and the second hook 221, the aluminum busbar 5 can be firmly fixed within the second mounting cavity 201, further enhancing the fixing stability.

[0036] Reference Figure 2For the layout of aluminum busbar 5 positioned at the bottom and low-voltage wiring harness 4 positioned at the top, the integrated fixing device for aluminum busbar and low-voltage wiring harness in this embodiment of the application further includes a connecting structure 3 for connecting to the vehicle body. The connecting structure 3 is a first buckle that secures the aluminum busbar fixing structure 2. Through the first buckle, the entire fixing device can be firmly installed on the vehicle body structure in the sill area, reducing the risk of being stepped on during the final assembly process due to wiring harness placement, and improving production efficiency and product quality.

[0037] Reference Figure 3 For the layout of aluminum busbar 5 on the right and low-voltage wiring harness 4 on the left, while maintaining the connection between the aluminum busbar and the wiring harness fixing structure, the low-voltage wiring harness 4 can be tied to the second buckle 6 with a standard cable tie, thus finally achieving fixation to the vehicle body structure.

[0038] In this embodiment, the low-voltage wiring harness fixing structure 1 and the aluminum busbar fixing structure 2 are made of PA66+GF30 engineering plastic. This composite material has high strength, high temperature resistance and good electrical insulation properties, which can effectively protect the low-voltage wiring harness and aluminum busbar, while reducing the weight of the device, reducing material costs and vehicle weight, and helping to improve the vehicle's fuel economy and driving range.

[0039] Combination Figure 2 and Figure 3 This application also provides a vehicle including the aforementioned integrated fixing device for aluminum busbar and low-voltage wiring harness, and further including low-voltage wiring harness 4 and aluminum busbar 5. The low-voltage wiring harness 4 passes through the first mounting cavity 101 and is fixed by the low-voltage wiring harness fixing structure 1, and the aluminum busbar 5 passes through the second mounting cavity 201 and is fixed by the aluminum busbar fixing structure 2.

[0040] In the case of vehicles, when the aluminum busbar 5 is positioned at the bottom and the low-voltage wiring harness 4 is positioned at the top, the integrated fixing device for the aluminum busbar and low-voltage wiring harness in this embodiment is connected and fixed to the vehicle body through the connecting structure 3. The connecting structure 3 is the first buckle that secures the aluminum busbar fixing structure 2. Through the first buckle, the entire fixing device can be firmly installed on the vehicle body structure in the door sill area, reducing the risk of being stepped on during the final assembly process due to the wiring harness arrangement, and improving production efficiency and product quality.

[0041] Reference Figure 3 For vehicles, when the aluminum busbar 5 is placed on the right and the low-voltage wiring harness 4 is placed on the left, the aluminum busbar can be tied to the low-voltage wiring harness 4 by the second buckle 6 with a standard cable tie while maintaining the connection between the aluminum busbar and the wiring harness fixing structure. Finally, the second buckle 6 is used to fix the aluminum busbar to the vehicle body structure.
