[0036] In order to solve the problem of poor sealing between a wire splitting device and a vehicle roof surface in the prior art, the present application provides a wire splitting device and a vehicle having the same.

[0037] like Figures 1 to 9 As shown, the wiring harness assembly is mounted on a vehicle roof 500, which has a wire hole 501. The wiring harness assembly includes a wiring harness body 100 and a sealing assembly 400. The wiring harness body 100 has a wire entry hole 102, a wire exit hole 103, and an installation cavity. The installation cavity communicates with both the wire entry hole 102 and the wire exit hole 103. The installation cavity is used to mount a wiring harness distributor 600, which is used for wiring harness distribution. The wire entry hole 102 communicates with the wire hole 501. The sealing assembly 400 is positioned between the wiring harness body 100 and the vehicle roof 500 to seal the wire hole 501 and the wire entry hole 102.

[0038] Using the technical solution of this embodiment, a wire splitter is installed on the roof surface 500. The wire harness to be split is routed through the wire splitter. The wire splitter 600 is used to split the wire harness 300, facilitating inspection and maintenance of the wire harness 300. Thus, after the wire splitter and the roof surface 500 are assembled, a sealing assembly 400 is installed between the wire splitter and the roof surface 500 to seal the connection between the two, thereby preventing impurities such as rainwater and dust from entering the vehicle body through the wire hole 501 in the roof surface 500. This solves the problem of poor sealing between the wire splitter and the roof surface in the prior art.

[0039] like Figure 7 As shown, the sealing assembly 400 includes a first connecting structure 420 and a first sealing structure 410. The first connecting structure 420 has a first via 424 that communicates with the wire inlet 102. The first connecting structure 420 is connected to both the branching body 100 and the vehicle roof 500. The first sealing structure 410 is disposed between the first connecting structure 420 and the branching body 100. Thus, the first sealing structure 410 is used to seal the connection between the first connecting structure 420 and the branching body 100, preventing impurities such as rainwater and dust from entering the branching device through the connection and causing electric shock.

[0040] Specifically, the first sealing structure 410 is a sealing ring, and the wiring harness 300 is disposed within the sealing ring and the first through-hole 424 to ensure that the wiring harness 300 can enter the branch line body 100. The first connecting structure 420 is an annular plate, which simplifies the structure of the sealing assembly 400 and makes it easier to manufacture and implement, thereby reducing the processing cost and difficulty of the sealing assembly 400.

[0041] like Figure 9 As shown, the sealing assembly 400 further includes a second connecting structure 440 and a second sealing structure 430. The second connecting structure 440 has a second through-hole 442 that communicates with the wire-through hole 501. The second connecting structure 440 is connected to both the first connecting structure 420 and the roof surface 500. The second sealing structure 430 is disposed between the first connecting structure 420 and the second connecting structure 440. Thus, the second sealing structure 430 is used to seal the connection between the second connecting structure 440 and the first connecting structure 420, preventing impurities such as rainwater and dust from entering the wire-dividing device through the connection and causing electric shock, thereby improving the overall sealing performance of the sealing assembly 400.

[0042] Specifically, the second sealing structure 430 is a sealing gasket, and the wiring harness 300 is disposed within the sealing gasket and the second through-hole 442 to ensure that the wiring harness 300 can enter the branch line body 100. The second connecting structure 440 is an annular plate, which simplifies the structure of the sealing assembly 400 and makes it easier to process and implement, thereby reducing the processing cost and difficulty of the sealing assembly 400.

[0043] Optionally, the second connecting structure 440 is connected and / or bonded to the roof surface 500 via fasteners. In this way, the above arrangement makes the connection between the second connecting structure 440 and the roof surface 500 more stable, preventing the two from being separated from each other and affecting the sealing effect of the sealing assembly 400. In this embodiment, the second connecting structure 440 is connected and bonded to the roof surface 500 via fasteners. Specifically, one end of the fastener passes through the branch line main body 100, the first connecting structure 420, the second sealing structure 430 and the second connecting structure 440 in sequence and is then tightened on the roof surface 500, so that the disassembly and assembly of the sealing assembly 400, the branch line main body 100 and the roof surface 500 is easier and simpler, reducing the difficulty of disassembly and assembly.

[0044] Optionally, the fastener is a screw or a bolt.

[0045] like Figures 7 to 9 As shown, the first connecting structure 420 has a first through-hole 421, the second sealing structure 430 has a second through-hole 431 and a third through-hole 432, and the second connecting structure 440 has a fourth through-hole 441. Thus, one end of the fastener passes through the branching body 100, the first through-hole 421, the second through-hole 431, and the fourth through-hole 441 in sequence before being tightened onto the roof surface 500. The third through-hole 432 is used to pass the wiring harness 300.

[0046] like Figure 7 As shown, the top surface of the first connecting structure 420 has a mounting groove 423 and a blind hole 422. The first sealing structure 410 is disposed within the mounting groove 423. A fastener is inserted through the branching body 100 and then disposed within the blind hole 422 to connect the first connecting structure 420 and the branching body 100. This arrangement, on the one hand, facilitates and simplifies the assembly and disassembly of the first sealing structure 410 and the first connecting structure 420, thereby reducing the difficulty of assembly and disassembly. Furthermore, the mounting groove 423 limits the position of the first sealing structure 410, preventing it from moving relative to the first connecting structure 420 and thus affecting its sealing reliability. Furthermore, the blind hole 422 can collect impurities such as rainwater and dust, further preventing them from entering the wire-passing hole 501.

[0047] In this embodiment, there are multiple blind holes 422, which are spaced apart along the circumference of the first connection structure 420. The mounting groove 423 is an annular groove located outside the blind holes 422 to prevent structural interference between the fastener and the first sealing structure 410.

[0048] like Figures 1 to 5 As shown, the wire distribution device also includes a wire collection structure 301. This structure is positioned within the wire outlet 103 and engages with the outlet 103 to prevent rotation. The structure 301 includes a first accommodating cavity for accommodating the wire harness 300. This structure constrains and protects the wire harness 300, ensuring a more uniform distribution of the wires 300 as they exit the wire distribution device. Furthermore, this arrangement prevents the structure 301 from rotating relative to the outlet 103, which could affect the stability of the wire collection.

[0049] Optionally, the outlet hole 103 is a waist-shaped hole, a polygonal hole, or an elliptical hole. In this way, the above arrangement makes the structure of the outlet hole 103 more diverse, thereby reducing the processing difficulty of the staff.

[0050] In this embodiment, the wire outlet hole 103 is a waist-shaped hole, and the outer peripheral surface of the wire collection structure 301 is a waist-shaped surface adapted to the waist-shaped hole, so that the disassembly and assembly of the wire collection structure 301 and the branching body 100 is easier and simpler, reducing the labor intensity of the staff.

[0051] like Figure 4 As shown, the wire collection structure 301 is annular, and the wire distribution device further includes a support structure 302. The support structure 302 is disposed within the wire collection structure 301 to support the wire collection structure 301. In this way, the support structure 302 is used to support the inner circumference of the wire collection structure 301 to prevent the wire collection structure 301 from deforming and squeezing the wire harness 300.

[0052] Optionally, the support structure 302 is an annular structure. In this way, the above arrangement makes the disassembly and assembly of the support structure 302 and the cable collection structure 301 easier and simpler, reduces the difficulty of disassembly and assembly, and also makes the structure of the support structure 302 simpler, easier to process and realize.

[0053] Optionally, the support structure 302 is made of a hard material.

[0054] like Figure 2 and Figure 4As shown, the line dividing body 100 includes a bottom plate 105 and a first side plate 106 connected to the bottom plate 105. The line inlet hole 102 is provided on the bottom plate 105, and the line outlet hole 103 is provided on the first side plate 106. The outer peripheral surface of the line collecting structure 301 has a first groove 3011. The line collecting structure 301 is passed through the line outlet hole 103 and part of the first side plate 106 is snap-fitted with the first groove 3011. In this way, the line collecting structure 301 is snap-fitted with the line dividing body 100, so that the disassembly and assembly of the two are easier and simpler, thereby reducing the difficulty of disassembly and assembly. At the same time, the above-mentioned arrangement makes the structure of the line dividing body 100 simpler, easier to process and realize, and reduces the processing cost of the line dividing device.

[0055] In this embodiment, the wire harness 300 passes through the bottom of the wire splitting device and exits from the side of the wire splitting device, so that the layout of the wire harness 300 is more reasonable to meet the user's needs.

[0056] like Figure 1 、 Figure 2 and Figures 4 to 6 As shown, the branching body 100 has a wire-changing hole 101, and the branching device further includes a wire-changing structure 120. The wire-changing structure 120 is provided on the branching body 100 and is located at the wire-changing hole 101. The wire-changing structure 120 includes a plurality of wire-accommodating portions 121 connected in sequence. Each wire-accommodating portion 121 has a second accommodating cavity for accommodating the wiring harness 300. In this way, if the wiring harness 300 in the branching device is damaged and cannot be used normally, the staff can insert a new wiring harness into the wire-changing structure 120 to replace the damaged wiring harness, thereby ensuring that the circuit in the vehicle can be normally connected.

[0057] like Figure 1 、 Figure 2 and Figures 4 to 6 As shown, the volume of each second accommodating cavity gradually increases along the direction from the wire-switching structure 120 to the wire-dividing body 100. This allows personnel to select the appropriate size of the wire-storing portion 121 based on the width and outer diameter of the wire harness, allowing the wire-switching structure 120 to accommodate wire harnesses of different sizes, broadening its applicability.

[0058] Specifically, each wire accommodating portion 121 is a hollow shaft segment, and a step surface is formed between two adjacent wire accommodating portions 121, so that the structure of the wire changing structure 120 is simpler, easier to process and implement, and the processing cost and difficulty of the wire changing structure 120 are reduced.

[0059] Optionally, the line-changing structure 120 is made of rubber or silicone.

[0060] Optionally, a groove is provided on the outer circumference of at least part of the wire accommodating portion 121. When the staff needs to change the wire, they select a wire accommodating portion 121 of appropriate size and cut it at the groove of the wire accommodating portion 121 using a tool such as scissors or a blade. The wire harness passes through the second accommodating cavity of the wire accommodating portion 121 and is inserted into the wire distribution body 100.

[0061] like Figure 2 and Figure 6 As shown, the line-dividing body 100 also includes a second side plate 107, the line-changing structure 120 is arranged on the second side plate 107, and the plurality of line-accommodating parts 121 include a first sub-line-accommodating part 1211, and the first sub-line-accommodating part 1211 is arranged closer to the second side plate 107 relative to the remaining line-accommodating parts 121. A second groove is provided on the outer peripheral surface of the first sub-line-accommodating part 1211, and the first sub-line-accommodating part 1211 is passed through the line-changing hole 101 and part of the second side plate 107 is engaged with the second groove. In this way, the above-mentioned arrangement makes the disassembly and assembly of the line-changing structure 120 and the line-dividing body 100 easier and simpler, and reduces the difficulty of disassembly and assembly. At the same time, the above-mentioned arrangement makes the structure of the line-dividing body 100 simpler, easier to process and realize, and reduces the processing cost of the line-dividing device.

[0062] like Figure 6 As shown, the plurality of wire accommodating portions 121 further include a second sub-wire accommodating portion 1212. The second sub-wire accommodating portion 1212 is disposed away from the second side plate 107 relative to the remaining wire accommodating portions 121, and the end of the second sub-wire accommodating portion 1212 away from the second side plate 107 is a sealed end. Thus, when the operator does not need to change wires, this arrangement prevents impurities such as rainwater and dust from entering the wire branching body 100 through the wire change hole 101, thereby improving the sealing performance of the wire branching device.

[0063] Optionally, at least two of the plurality of second accommodating cavities are interconnected. In this way, when a worker needs to change a line, the above arrangement ensures that the wiring harness can pass through the second accommodating cavity into the line-changing hole 101, thereby improving the line-changing reliability of the line-changing structure 120.

[0064] like Figure 3 As shown, the wire splitting device further includes a cover plate 200 and a third sealing structure 201. The cover plate 200 is positioned over the wire splitting body 100, with the third sealing structure 201 disposed between the cover plate 200 and the wire splitting body 100. The cover plate 200 is provided with reinforcing ribs 202 and a blocking piece 203. The reinforcing ribs 202 enhance the structural strength of the cover plate 200, while the blocking piece 203 acts as a stop to prevent the third sealing structure 201 from shifting relative to the cover plate 200 and affecting the sealing effect.

[0065] The present application further provides a vehicle (not shown), comprising a vehicle body and a line dividing device provided on the vehicle body, wherein the vehicle body has a roof surface 500. The line dividing device is the above-mentioned line dividing device.

[0066] like Figure 1 and Figure 2 As shown, a limiting structure 700 is provided on the vehicle roof surface 500, and the limiting structure 700 cooperates with the stopper of the wire splitting device. Thus, after the wire splitting device and the vehicle body are assembled, the limiting structure 700 can position the wire splitting device to prevent relative movement between the wire splitting device and the vehicle roof surface 500, which would affect the stability of the connection between the two.

[0067] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0068] The wiring harness is placed on the roof of the vehicle, and the wiring harness that needs to be split is passed through the wiring harness. The wiring harness is split by the wiring harness, making it easier for workers to inspect and maintain the wiring harness. Once the wiring harness is assembled with the roof, a sealing assembly is installed between the wiring harness and the roof to seal the connection between the two, thereby preventing impurities such as rainwater and dust from entering the vehicle body through the wiring holes in the roof. This solves the problem of poor sealing between the wiring harness and the roof in the prior art.
