The current common tee design is plastic or aluminum tubes with more conventional structures, and the existing structure cannot meet the layout requirements of the vehicle circuit. Specifically, although the processing technology of plastic tees is simple, they are not resistant to high temperatures and are easy to melt in high-temperature circuits or affect durability and other performance, making them unsuitable for vehicle circuits. Aluminum tees have many structural constraints, and can only be realized by opening bypass holes in straight sections, which cannot meet the vehicle layout requirements of bypassing at the bends of aluminum tubes.

[0003] Therefore, a multi-way pipe is urgently needed to solve the above problems. Utility Model Content

[0024] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0025] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0026] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects before and after are in an "and / or" relationship.

[0027] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0028] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0029] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0030] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0031] like Figure 1 As shown, the multi-way tube of this embodiment is made of metal. Optionally, the multi-way tube is an aluminum tube to ensure high structural strength and light weight. The multi-way tube includes a two-way elbow 1 and N branch tubes 2, wherein the two-way elbow 1 includes a first straight tube section 11, an elbow section 12 and a second straight tube section 13 connected in sequence, and the elbow section 12 is provided with N assembly holes, where N is a positive integer. The N branch tubes 2 are interference-inserted in the N assembly holes one by one, and the N branch tubes 2 are all welded to the elbow section 12. Since the N branch tubes 2 are all located in the elbow section 12, the multi-way tube can meet the vehicle layout requirements of bypassing the bends of the tubes. The value of N can be selected according to the actual situation of the vehicle layout. Figure 1 The three-way valve that meets the above description is shown when N is 1. Of course, N can also be 2, 3, 4, 5, or other positive integers.

[0032] Optionally, M branches 2 are evenly spaced along the extension direction of the bend section 12, or M branches 2 are evenly spaced along the circumference of the bend section 12, and M is a positive integer less than or equal to N. That is, some or all of the branches 2 are evenly spaced along the extension direction of the bend section 12, or are evenly spaced along the circumference of the bend section 12. Taking M as 4 as an example, the four branches 2 can all be located on the outermost curved surface of the bend section 12 and evenly spaced, and their distribution is similar to the needle-shaped dorsal fin of an animal. Or the four branches 2 can be evenly spaced along the circumference of the bend section 12, that is, one branch 2 is set every 90°, so as to facilitate docking of equipment in four different directions. If N is a positive integer greater than 4 such as 5, 6, etc., four branches 2 are arranged according to the above rules, and the positions of the remaining branches 2 can be adjusted according to actual needs, and there is no restriction here.

[0033] Optionally, the first straight pipe section 11 and the second straight pipe section 13 are both in the first plane, and A branches 2 are located in the first plane, where A is a positive integer less than or equal to N. That is, some or all of the branches 2 are in the same plane as the first straight pipe section 11 and the second straight pipe section 13. In the above example, the four branches 2 that are all located on the outermost curved surface of the curved pipe section 12 meet the requirement of being all located in the first plane. Of course, the remaining branches 2 may not be located in the first plane, or it may be set that all the branches 2 are not located in the first plane. For example, the four branches 2 that are evenly spaced along the circumference of the curved pipe section 12 in the above example are not in the first plane.

[0034] Optionally, the extension directions of B branch pipes 2 converge at the same point, and B is a positive integer less than or equal to N.

[0035] Optionally, a first limiting protrusion 21 is provided on the branch pipe 2 to clamp the branch pipe 2 and insert it into the assembly hole with interference fit, and the first limiting protrusion 21 can also have a limiting effect when docking with external equipment. Optionally, a first guiding groove is provided on the first limiting protrusion 21 to provide guidance when docking with external equipment.

[0036] Optionally, a second limiting protrusion 111 is provided on the first straight pipe section 11 and / or the second straight pipe section 13 to limit the position when docking with external equipment. Optionally, a second guiding groove 1111 is provided on the second limiting protrusion 111 to guide when docking with external equipment.

[0037] Optionally, the ends of the first straight pipe section 11 and / or the second straight pipe section 13 are provided with a pier head 112. Optionally, the ends of the first straight pipe section 11 and / or the second straight pipe section 13 are provided with a chamfer. Optionally, the ends of the branch pipe 2 are provided with a pier head 112. Optionally, the ends of the branch pipe 2 are provided with a chamfer.

[0038] Figure 1 The branch pipe 2 of the tee pipe shown is arranged on the outermost curved surface of the curved pipe section 12, and the angle between the length direction of the branch pipe 2 and the axial direction of the first straight pipe section 11 is 30°. Of course, the angle between the length direction of the branch pipe 2 and the first straight pipe section 11 and the second straight pipe section 13 can be adjusted according to actual needs.

[0039] The manufacturing process of the multi-way pipe includes the following steps:

[0040] First, a two-way elbow 1 is manufactured, and chamfering and piercing 112 are performed on the straight pipe blanking, and then the straight pipe is bent and pierced 112, pit punching and other processes related to the bending pipe are performed; then laser drilling is performed at the required bending position of the elbow to form an assembly hole, and finally cleaning and inspection are performed.

[0041] Then the branch pipe 2 is manufactured, and after blanking and chamfering, the two limiting pier heads 112 for pre-assembly and assembly with the hand parts are completed, and finally cleaned and inspected.

[0042] Finally, the branch pipe 2 is pressed into the assembly hole of the two-way elbow pipe 1, and gaskets, welding rings and other flux materials are used in the middle to ensure that there is no leakage at the assembly during the welding process. After the manufacture of the above-mentioned multi-way pipe is completed, the multi-way pipe is installed in the required pipeline assembly, and the final qualified pipe assembly can be completed by flame brazing or high-temperature brazing furnace dedicated to the assembly product. The multi-way pipe can be used in the fuel pipeline, coolant pipeline, exhaust pipeline and other loop assemblies of the whole vehicle, and can meet the complex structural design of the whole vehicle loop to a large extent. It is a great improvement over the conventional situation that only bypass branches can be added to the straight section of the aluminum tube, and then the bypass branches are bent in multiple places to meet the loop interface requirements.

[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
