[0001] This invention relates to the field of vehicles, and in particular to a vehicle piping installation head, piping structure, and vehicle. Background Technology

[0002] With the development of new energy vehicles and hybrid vehicles, users have increasingly higher requirements for battery range. During vehicle operation, the battery typically generates heat, causing the battery pack temperature to rise, which in turn affects the battery pack's performance and lifespan. Therefore, a cooling system is needed to cool the battery. In existing technologies, the installation of a cooling system usually involves first installing the four-way piping to the vehicle body, then assembling the coolant hoses, and finally installing the subframe and tightening it with screws / nuts. The entire installation process is complex and makes it difficult to ensure a proper seal between the cooling system and the vehicle body after installation.

[0003] Therefore, a new type of automotive piping connector is needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a vehicle pipe installation head, pipe structure, and vehicle, which has a simple structure, is easy to install, and can ensure the sealing between the pipe structure and the vehicle.

[0005] The present invention provides a vehicle pipe installation head, including a mounting plate, two branch pipes located on one side of the mounting plate, and a main pipe located on the other side of the mounting plate and communicating with the branch pipes. The mounting plate is provided with a snap-fit ​​component, and the snap-fit ​​component and the branch pipes are located on the same side of the mounting plate.

[0006] Furthermore, the snap-fit ​​component is provided with a snap-fit ​​portion that can be elastically deformed, and a gap is provided between the snap-fit ​​portion and the mounting plate.

[0007] Furthermore, the mounting plate is provided with a sealing gasket, which is square in shape and has an opening in the middle for the branch pipe and the snap-fit ​​component to pass through.

[0008] Furthermore, a positioning pin is provided at the lower part of the main pipeline, the positioning pin is perpendicular to the mounting plate, and the positioning pin breaks off from the main pipeline when subjected to force.

[0009] The present invention provides a pipeline structure, including the vehicle pipeline mounting head as described in any one of the above, and further including a cooling water pipe, wherein the cooling water pipe is connected to the main pipeline.

[0010] Furthermore, the cooling water pipe includes a corrugated pipe and a nylon pipe connected to the corrugated pipe, the corrugated pipe being connected to both ends of the main pipeline.

[0011] The present invention provides a vehicle including the above-described piping structure, and also including a vehicle body and a subframe assembled on the vehicle body. The piping structure is assembled onto the subframe and then assembled with the vehicle body.

[0012] Furthermore, the sheet metal parts of the vehicle body are provided with fixing holes, and the snap-fit ​​component passes through the fixing holes and snaps onto the sheet metal parts. The sealing gasket is located between the mounting plate and the sheet metal parts, and the sheet metal parts are engaged in the gap.

[0013] Furthermore, the cooling water pipe is provided with a fixed bracket, and the cooling water pipe is fixed to the subframe through the fixed bracket.

[0024] like Figure 1As shown, the present invention provides a vehicle piping installation head 100, which is assembled together with a piping structure 200 on a vehicle 300. The vehicle piping installation head 100 includes a mounting plate 11, two branch pipes 12 located on one side of the mounting plate 11, and a main pipe 13 located on the other side of the mounting plate 11 and communicating with the branch pipes 12. After the vehicle piping installation head 100 is installed on the vehicle body 31, the two branch pipes 12 are located inside the vehicle body 31, and the main pipe 13 is located outside the vehicle body 31.

[0025] like Figure 2 and Figure 3 As shown, the branch pipe 12 is cylindrical. To facilitate the installation of the branch pipe 12 into the vehicle body 31, the branch pipe 12 is provided with a quick-connect structure or a clamp structure. In some embodiments, the branch pipe 12 is provided with a quick-connect structure, specifically: the middle part of the branch pipe 12 is provided with at least two protrusions, the outer diameter of the protrusions is larger than the overall outer diameter of the branch pipe 12, and a groove 122 is provided between the protrusions.

[0026] The uppermost protrusion of the branch pipe 12 is a sloping protrusion 121. The sloping surface of the protrusion 121 is formed by extending the surface of the branch pipe 12 towards the protrusion, facilitating the quick insertion of the branch pipe 12 into the vehicle body 31. In this embodiment, to ensure effective insertion and fixation after insertion, two grooves 122 are formed between the protrusions on the branch pipe 12. That is, by providing the sloping protrusion 121 and multiple grooves 122 on the branch pipe 12, the branch pipe 12 can be quickly inserted into the vehicle body 31. In other embodiments, the branch pipe 12 is provided with a clamping structure to facilitate the mating of the branch pipe 12 with the vehicle body 31.

[0027] The main pipe 13 connects vertically to two branch pipes 12. Specifically, the main pipe 13 includes a left main pipe 131 and a right main pipe 132, both with the same inner diameter. A connecting portion 133 is provided between the left main pipe 131 and the right main pipe 132. The inner diameter of the connecting portion 133 is smaller than that of the left and right main pipes 131 and 132. This structure ensures the flow of coolant inside the entire pipe mounting head 100, improving the cooling effect. Both the left and right main pipes 131 and 132 have mounting portions 134 at their outlets. Each mounting portion 134 has a sealing structure 135, which improves the sealing effect between the mounting portion 134 and the cooling water pipe 21.

[0028] The mounting plate 11 is provided with a snap-fit ​​member 14 that can elastically deform, and the snap-fit ​​member 14 and the branch pipe 12 are located on the same side of the mounting plate 11. When the pipe mounting head 100 is installed to the vehicle body 31, the snap-fit ​​member 14 is used to snap into the vehicle body 31. In this embodiment, the snap-fit ​​member 14 is provided with a snap-fit ​​part 141, which can elastically deform under force, and a gap 142 is provided between the snap-fit ​​part 141 and the mounting plate 11.

[0029] In another embodiment, the snap-fit ​​member 14 includes a snap-fit ​​portion that can be elastically deformed and a fixing portion that is fixed on the mounting plate. The snap-fit ​​portion is disposed on the fixing portion, and a gap is provided between the bottom of the snap-fit ​​portion and the mounting plate 11.

[0030] To ensure a good seal, the mounting plate 11 is provided with a sealing gasket 111, which has a square frame structure. The sealing gasket 111 has an opening 112 for two branch pipes 12 and two snap-fit ​​fittings 14 to pass through.

[0031] The lower part of the main pipeline 13 is provided with a positioning pin 15, which is perpendicular to the mounting plate 11. In this embodiment, the positioning pin 15 is fixed to the main pipeline 13 by heat fusion. When the positioning pin 15, the mounting plate 11, and the main pipeline 13 are subjected to forces in different directions, the positioning pin 15 will break off from the main pipeline 13.

[0032] like Figure 5 As shown, the present invention provides a pipeline structure 200, which includes a vehicle pipeline mounting head 100 and a cooling water pipe 21 mounted on the pipeline mounting head 100. Specifically, the cooling water pipe 21 is mounted on the mounting portions 134 at both ends of the main pipeline 13 by cooperating with a sealing structure 135.

[0033] The cooling water pipe 21 includes a corrugated pipe 211 and a nylon pipe 212 connected to the corrugated pipe 211, wherein the corrugated pipe 211 is connected to the mounting part 134. A fixing bracket 213 is also provided on the nylon pipe 212 of the cooling water pipe 21, and the cooling water pipe 21 is fixed to the subframe 32 by the fixing bracket 213.

[0034] The piping structure 200 is applied to the vehicle 300, which has a body 31 and a subframe 32 assembled on the body 31. For example... Figure 4 As shown, when assembling the piping structure 200, first insert the positioning pin 15 into the positioning hole 321 on the subframe 32 to initially position the vehicle piping installation head 100 to the subframe 32; then, fix the coolant pipe 21 to the subframe 32 using the fixing bracket 213, so that the pipe installation head 100 is close to the subframe 32. There is a gap between the coolant pipe 21 and the vehicle body 31. During vehicle operation, when there is relative movement between the subframe 32 and the vehicle body 31, the corrugated part of the coolant pipe 21 can absorb the movement and act as a buffer.

[0035] The piping structure 200 and subframe 32 are then lifted together to mate with the sheet metal part 311 on the body 31. The sheet metal part 311 has a fixing hole (not shown) for the snap-fit ​​part 14 to pass through. An upward pulling force is applied to the piping structure 200, causing the snap-fit ​​portion 141 of the snap-fit ​​part 14 to deform and pass through the fixing hole on the sheet metal part 311. The snap-fit ​​part 14 then returns to its original shape, and the snap-fit ​​portion 141 engages with the sheet metal part 311. This brings the mounting plate 11 closer to the sheet metal part 311, causing the sheet metal part 311 to press the sealing gasket 111 firmly and simultaneously engage in the gap 142 between the snap-fit ​​portion 141 and the mounting plate 11. At this point, the sealing gasket 111 is located between the mounting plate 11 and the sheet metal part 311.

[0036] After the piping structure 200 and subframe 32 are installed onto the vehicle body 31, a small force is applied to the locating pin 15 to disconnect it from the main piping 13 and detach it. At this point, there is space between the piping mounting head 100 and the subframe 32. The locating pin 15 ensures that the piping structure 200 and subframe 32 can be accurately installed onto the vehicle body 31, and allows for gaps between the piping structure 200 and surrounding components after installation.

[0037] The pipe mounting head 100, pipe structure 200, and vehicle 300 provided by this invention feature a snap-fit ​​component 14 and a sealing gasket 111 on the mounting plate 11. The snap-fit ​​component 14 engages with the sheet metal part 311, allowing the pipe mounting head 100 to be easily installed onto the vehicle body 31 while ensuring both fixation and sealing. By providing a detachable positioning pin 15 on the main pipe 13, the pipe structure 200 can be initially positioned onto the subframe 32 using the positioning pin 15 during installation. Then, the subframe 32 and pipe structure 200 are installed as a whole onto the vehicle body 31. Finally, force is applied to the positioning pin 15 to detach it from the main pipe 13. The positioning pin 15 ensures precise positioning of the subframe 32 and pipe structure 200 with the fixing holes of the sheet metal part 311, reducing installation difficulty.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any modifications, equivalent substitutions, improvements, etc., made within the scope of the present invention should be included within the scope of protection of the present invention.
