[0038] This embodiment provides a commercial vehicle, which includes a frame on which a flywheel housing and a battery pack side panel are fixedly mounted. The commercial vehicle also includes a wiring structure. The wiring structure is located at the bottom of the flywheel housing and includes a wiring groove 1 and a junction box 2. The wiring groove 1 includes a U-shaped groove body 11 and a fixing member. The U-shaped groove body 11 is fixed to the bottom of the flywheel housing, and the fixing member is located inside the U-shaped groove body 11 and used to fix the wire harness inside the U-shaped groove body 11. The junction box 2 is located on one side of the wiring groove 1 and is fixed to the battery pack side panel. The junction box 2 has a first wiring hole 201 at its first end and a second wiring hole 202 at its second end. A fixing post 23 is located inside the junction box 2, and the fixing post 23 is used to install a terminal block. The terminal block is used to electrically connect two wire harnesses that pass through the first wiring hole 201 and the second wiring hole 202 into the junction box 2, respectively.

[0039] In this embodiment, the wiring structure includes two parts: a wiring trough 1 and a junction box 2. The wiring trough 1 includes a U-shaped trough body 11 and a fixing member disposed within the U-shaped trough body 11. The U-shaped trough body 11 is fixed to the bottom of the flywheel housing, and the wire harness can pass through the U-shaped trough and be fixed by the fixing member. The junction box 2 is disposed on one side of the wiring trough 1 and fixed to the side baffle of the battery frame. The junction box 2 has a first wiring hole 201 at its first end and a second wiring hole 202 at its second end. The junction box 2 contains a fixing post 23 for installing terminals. When a terminal is installed on the fixing post 23, the two wire harnesses pass through the first wiring hole 201 and the second wiring hole 202 respectively into the junction box 2 and simultaneously extend to the fixing post 23, achieving electrical connection between the two wire harnesses through the terminals. Specifically, using this wiring structure, the original single wire harness can be divided into two sections. For example, the two sections can be respectively... Figure 1 The first wiring harness 31 and the second wiring harness 32 are both high-current wiring harnesses. Specifically, the first wiring harness 31 is laid out from inside the U-shaped groove body 11 and then extends into the first wiring hole 201, while the second wiring harness 32 extends into the second wiring hole 202. The first wiring harness 31 and the second wiring harness 32 are electrically connected through a terminal block. This method of cutting and separating a single high-current wiring harness and achieving electrical connection effectively reduces the difficulty of laying high-current wiring harnesses, making the wiring harness easier to arrange. Furthermore, the wiring harness is mainly laid at the bottom of the flywheel housing, eliminating the need to lay it across the left and right sides of the vehicle frame, thus facilitating inspection and maintenance. The commercial vehicle provided in this embodiment, including the above-mentioned wiring structure, effectively reduces the difficulty of laying high-current wiring harnesses, making the wiring harness easier to arrange. The wiring harness is mainly laid at the bottom of the flywheel housing, eliminating the need to lay it across the left and right sides of the vehicle frame, thus facilitating inspection and maintenance.

[0040] In this embodiment, the U-shaped groove body 11 is shaped like an arc to fit the outer surface of the flywheel housing. This design allows the U-shaped groove body 11 to fit more closely to the outer surface of the flywheel housing, facilitating positioning and installation. Furthermore, the U-shaped groove body 11 is provided with multiple fixing parts 12 for fixing to the bottom of the flywheel housing. The fixing parts 12 achieve a fixed connection between the U-shaped groove body 11 and the flywheel housing.

[0041] Specifically, the fixing part 12 has a first mounting hole 121, and the flywheel housing has a corresponding first screw hole. A first bolt passes through the first mounting hole 121 and is threaded into the first screw hole. Specifically, the first mounting hole 121, the first screw hole, and the first bolt are arranged in a one-to-one correspondence; the number can be one set or multiple sets. Specifically, the docking box 2 has a second mounting hole 211, and the battery frame side baffle has a corresponding second screw hole. A second bolt passes through the second mounting hole 211 and is threaded into the second screw hole. Specifically, the second mounting hole 211, the second screw hole, and the second bolt are arranged in a one-to-one correspondence; the number can be one set or multiple sets.

[0042] Specifically, the first mounting hole 121 has a diameter of 7mm, and the first bolt is an M6 bolt. The second mounting hole 211 has a diameter of 15mm, and the second bolt is an M14 bolt.

[0043] Alternatively, the fixing part 12 can be fixedly connected to the flywheel housing by a snap-fit ​​structure or by using screws or other connectors. The docking box 2 can also be fixedly connected to the battery frame side panel by a snap-fit ​​structure or by using screws or other connectors.

[0044] In this embodiment, the docking box 2 is provided with a snap-fit ​​rib 24 for engaging with the battery frame side baffle. By providing the snap-fit ​​rib 24, it can engage with the battery frame side baffle, thereby achieving positioning between the docking box 2 and the battery frame side baffle, facilitating quick and reliable fixation of the two and preventing the docking box 2 from moving freely.

[0045] In this embodiment, the fastener includes wire clamps 13 spaced apart along the extension direction of the U-shaped groove body 11. Specifically, the wire clamps 13 are detachably mounted relative to the U-shaped groove body 11. First, the wire clamps 13 can be clipped onto the wire harness, and then they can be fixedly mounted together on the U-shaped groove body 11.

[0046] Alternatively, the wire clamp 13 and the U-shaped groove body 11 can also be fixedly connected by setting a snap-fit ​​structure or by using screws or other connectors.

[0047] Specifically, the surface of the wire clamp 13 can be treated with a plastic slurry process to prevent the metal edges from causing wear on the wire harness.

[0048] In this embodiment, the U-shaped groove body 11 is provided with a plurality of reinforcing ribs 16 at intervals along its extension direction. The provision of reinforcing ribs 16 further enhances the overall strength of the U-shaped groove body 11.

[0049] In this embodiment, the U-shaped groove body 11 is provided with a plurality of first cable tie holes 14 for the cable harness to pass through. By providing the first cable tie holes 14, the cable harness can pass through the first cable tie holes 14 and be tied to the cable harness inside the U-shaped groove body 11, thereby achieving further fixation of the cable harness inside the U-shaped groove.

[0050] In this embodiment, the U-shaped groove body 11 is provided with a plurality of drainage holes 15 for drainage. The drainage holes 15 are provided to drain water from the U-shaped groove body 11 in a timely manner, prevent water accumulation in the U-shaped groove body 11, and thus avoid short circuits in the wire harness.

[0051] In this embodiment, a first sealing ring 251 is provided in the first wiring hole 201, and a second sealing ring 252 is provided in the second wiring hole 202. The first sealing ring 251 can effectively seal the gap between the first wiring hole 201 and the wire harness through which it is inserted; the second sealing ring 252 can effectively seal the gap between the second wiring hole 202 and the wire harness through which it is inserted, thus effectively ensuring airtightness.

[0052] For example, both the first sealing ring 251 and the second sealing ring 252 are made of rubber.

[0053] In this embodiment, the axes of the first wiring hole 201 and the second wiring hole 202 are arranged parallel and spaced apart. This arrangement ensures that there is a gap between the two wire harnesses that pass through the first wiring hole 201 and the second wiring hole 202 respectively, which corresponds to the lengths of the two ends of the terminal block, so that the two ends of the terminal block can be effectively connected to the two wire harnesses respectively.

[0054] In this embodiment, the docking box 2 has a wire passage groove 212 for wire harnesses to pass through. The wire passage groove 212 can also accommodate wire harnesses other than high-current wire harnesses, such as ground wires. In this embodiment, the wire passage groove 212 has multiple second cable tie holes 2121 for cable ties to pass through. By providing the second cable tie holes 2121, cable ties can pass through the second cable tie holes 2121 and be tied to the wire harness within the wire passage groove 212, thereby further securing the wire harness within the wire passage groove 212.

[0055] In this embodiment, the docking box 2 includes a first box portion 21 and a second box portion 22 that are snapped together, and a fixing post 23 is fixed inside the first box portion 21 or the second box portion 22. The first box portion 21 has a first wiring groove 2011 at its first end, and the second box portion 22 has a second wiring groove 2012 at its first end. The first wiring groove 2011 and the second wiring groove 2012 together form a first wiring hole 201. The first box portion 21 has a third wiring groove 2021 at its second end, and the second box portion 22 has a fourth wiring groove 2022 at its second end. The third wiring groove 2021 and the fourth wiring groove 2022 together form a second wiring hole 202. Specifically, one of the first box portion 21 and the second box portion 22 has a snap-fit ​​groove 213, and the other has a corresponding snap-fit ​​connector 221. The first box portion 21 and the second box portion 22 are fixed together by the snap-fit ​​between the snap-fit ​​groove 213 and the snap-fit ​​connector 221.

[0056] Optionally, multiple slots 213 and connectors 221 are provided in a one-to-one correspondence.

[0057] Optionally, a third sealing ring is provided between the first box portion 21 and the second box portion 22. The third sealing ring can effectively seal the gap between the first box portion 21 and the second box portion 22, effectively ensuring airtightness.

[0058] For example, the third sealing ring is made of rubber.

[0059] In this embodiment, the second box portion 22 is provided with an installation direction mark 222. Specifically, the installation direction mark 222 may be configured as multiple arrows.
