[0002] In the fuel system, ventilation system and the like of a vehicle, multiple pipelines are included, and two pipelines in communication with each other can be connected through a joint assembly. The joint assembly generally includes a female joint and a male joint. One of the pipelines is fixedly connected to the female joint, and the other pipeline is fixedly connected to the male joint. The male joint is inserted into the female joint, and the two are locked to achieve the connection between the two pipelines.
[0003] Since vibrations are inevitably generated during the driving of a vehicle, in order to ensure the stability of the connection between the pipelines and to avoid interference between the pipelines and other components, a joint assembly with a limiting function is generally used to connect the pipelines in the related art. For example, a limiting groove can be provided on one of the female joint and the male joint, and a limiting protrusion can be provided on the other. When the female joint and the male joint are assembled, the limiting protrusion and the limiting groove need to be aligned before the two can be inserted and assembled.

The following embodiments are used to explain the present application, but not to limit the scope of the present application.

Rather, the words such as "exemplary" or "for example" are intended to present the relevant concept in a specific manner.
[0054] As described in the background, the joint assembly with the limiting function in the related art solution needs the assembler to align the limiting protrusion and the limiting groove before the plug-in assembly can be achieved, and blind assembly of the joint assembly cannot be achieved. In new energy vehicles, due to the large number of parts of the vehicle, the assembly space of the pipeline is small, and the assembly difficulty and efficiency of the above solution are high.
[0055] Therefore, embodiments of the present application aim to provide a joint assembly, a pipeline system and a vehicle. A first limiting groove and a second limiting groove are arranged on one of the male joint and the female joint, a first limiting protrusion and a second limiting protrusion are arranged on the other of the male joint and the female joint, and the first limiting protrusion and the second limiting protrusion are both elastic protrusions. When the male joint is inserted into the female joint, with the insertion of the male joint, the first limiting protrusion and the second limiting protrusion can be compressed, so as to ensure that the male joint can smoothly enter the receiving channel of the female joint. With further insertion of the male joint, the first limiting protrusion reaches the first limiting groove and is clamped in the first limiting groove. Then the assembler can rotate the male joint, so that the second limiting protrusion falls into the second limiting groove, the male joint is locked relative to the female joint, and the joint assembly is connected. The whole connection process of the embodiments of the present application does not need the operator to visually assemble, and blind assembly of the joint assembly can be achieved. Compared with the solution in the related art, the embodiments of the present application improve the assembly efficiency of the joint assembly and reduce the assembly difficulty of the joint assembly.
[0056] In the following, embodiments of the present application are described in detail in conjunction with the drawings, in which examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.
[0057] Embodiments of the present application provide a joint assembly, a pipeline system and a vehicle for connection of pipelines in a vehicle. It should be noted that the vehicle in the present application can refer to large cars, small cars, special purpose cars and the like. For example, according to the vehicle type, the car in the present application can be a sedan type, an off-road type, a multi-purpose vehicle (MPV) type or other types. For vehicles, a vehicle body is generally provided, and the fuel, ventilation and other systems in the vehicle body all include multiple pipelines, and the connection between two pipelines in communication can be achieved through a joint assembly. The joint assembly generally includes a female joint and a male joint. One of the pipelines is fixedly connected to the female joint, and the other pipeline is fixedly connected to the male joint. The male joint is inserted into the female joint, and the two are locked to achieve communication between the two pipelines.
[0058] Please refer to Figures 1-11The application provides a joint assembly, comprising:
[0059] The female joint 100 is internally formed with a receiving channel 1100; it can be understood that the receiving channel 1100 penetrates the female joint 100 in the axial direction, and the inner diameter of the receiving channel 1100 is greater than the outer diameter of the male joint 200, so that the female joint 100 can accommodate the male joint 200.
[0060] The male joint 200 is internally formed with a communicating channel 2100; it can be understood that the communicating channel 2100 penetrates the male joint 200 in the axial direction, and after the female joint 100 and the male joint 200 are connected, two pipelines are communicated through the communicating channel 2100.
[0061] In the application, one of the male joint 200 and the female joint 100 is provided with a first limiting groove 210 and a second limiting groove 220, the first limiting groove 210 is arranged in the circumferential direction of the joint assembly, and the second limiting groove 220 is arranged in the axial direction of the joint assembly. The other of the male joint 200 and the female joint 100 is provided with a first limiting protrusion 311 and a second limiting protrusion 321, the first limiting protrusion 311 and the second limiting protrusion 321 are both elastic protrusions, and the first limiting protrusion 311 and the second limiting protrusion 321 are arranged in the axial direction of the joint assembly. Exemplarily, when the first limiting groove 210 and the second limiting groove 220 are arranged on the male joint 200, the first limiting groove 210 and the second limiting groove 220 can be located on the outer surface of the male joint 200; correspondingly, the first limiting protrusion 311 and the second limiting protrusion 321 are arranged on the female joint 100, and the first limiting protrusion 311 and the second limiting protrusion 321 can be located on the inner surface of the female joint 100; since the first limiting protrusion 311 and the second limiting protrusion 321 are both elastic protrusions, the male joint 200 can compress the first limiting protrusion 311 and the second limiting protrusion 321 in the process of being inserted into the female joint 100, so as to ensure that the male joint 200 can be smoothly inserted into the female joint 100. When the first limiting groove 210 and the second limiting groove 220 are arranged on the female joint 100, the first limiting groove 210 and the second limiting groove 220 can be located on the inner surface of the female joint 100; correspondingly, the first limiting protrusion 311 and the second limiting protrusion 321 are arranged on the male joint 200, and the first limiting protrusion 311 and the second limiting protrusion 321 can be located on the outer surface of the male joint 200; since the first limiting protrusion 311 and the second limiting protrusion 321 are both elastic protrusions, the first limiting protrusion 311 and the second limiting protrusion 321 are compressed by the female joint 100 in the process of being inserted into the female joint 100, so as to ensure that the male joint 200 can be smoothly inserted into the female joint 100.
[0062] In the process of inserting the male connector 200 into the female connector 100, the male connector 200 and the female connector 100 have a first state, a second state and a third state relative to each other. For example, the first limiting recess 210 and the second limiting recess 220 are arranged on the male connector 200, and the first limiting protrusion 311 and the second limiting protrusion 321 are arranged on the female connector 100. Figure 4 and Figure 5 As shown in FIG. 1A and FIG. 1B, before reaching the first state, the first limiting protrusion 311 and the second limiting protrusion 321 interfere with the male connector 200 along the axial direction of the connector assembly.
[0063] The male connector 200 is continuously inserted into the female connector 100, and the male connector 200 and the female connector 100 reach the first state. In the first state, the first limiting protrusion 311 and the second limiting protrusion 321 are compressed by the male connector 200, so that the male connector 200 can enter the female connector 100.
[0064] The male connector 200 is continuously inserted into the female connector 100, and the male connector 200 and the female connector 100 reach the second state. In the second state, the first limiting protrusion 311 is clamped in the first limiting recess 210, the second limiting protrusion 321 is compressed, and the male connector 200 can rotate relative to the female connector 100, but cannot continue to move along the axial direction of the connector assembly.
[0065] On the basis of the second state, the male connector 200 and the female connector 100 reach the third state by rotating the male connector 200. In the third state, the first limiting protrusion 311 is clamped in the first limiting recess 210, the second limiting protrusion 321 is clamped in the second limiting recess 220, and the male connector 200 and the female connector 100 are relatively locked (as shown in FIG. 1C). Figure 2
[0066] It can be understood that, since the cooperation process of the first limiting protrusion 311 and the first limiting recess 210 does not need to be visually inspected by an assembler, and the second limiting protrusion 321 can be clamped in the second limiting recess 220 by rotating the male connector 200 after the first limiting protrusion 311 and the first limiting recess 210 are clamped, thereby limiting the male connector 200 and the female connector 100, and this process also does not need to be visually inspected by an assembler, therefore the embodiment of the present application can realize blind assembly of the connector assembly.
[0067] The first limiting groove 210 and the second limiting groove 220 are arranged on one of the male connector 200 and the female connector 100, the first limiting protrusion 311 and the second limiting protrusion 321 are arranged on the other one of the male connector 200 and the female connector 100, and the first limiting protrusion 311 and the second limiting protrusion 321 are both elastic protrusions. When the male connector 200 is inserted into the female connector 100, the first limiting protrusion 311 and the second limiting protrusion 321 can be compressed with the insertion of the male connector 200, so as to ensure that the male connector 200 can smoothly enter the receiving channel 1100 of the female connector 100. With further insertion of the male connector 200, the first limiting protrusion 311 reaches the first limiting groove 210 and is clamped in the first limiting groove 210, and the connector assembly emits a first clamping sound of 'click'. Then the assembler can rotate the male connector 200, so that the second limiting protrusion 321 falls into the second limiting groove 220, and the connector assembly emits a second clamping sound of 'click', the male connector 200 is relatively locked with the female connector 100, and the connection of the connector assembly is completed.
[0068] The whole connection process of the embodiment of the present application does not need the assembler to visually assemble, and blind assembly of the connector assembly can be realized. Compared with the scheme in the related art, the embodiment of the present application improves the assembly efficiency of the connector assembly and reduces the assembly difficulty of the connector assembly.
[0069] Preferably, the first limiting groove 210 and the second limiting groove 220 are located on the male connector 200 in the embodiment of the present application. The first limiting protrusion 311 and the second limiting protrusion 321 are located on the female connector 100.
[0070] The embodiment of the present application sets the first limiting groove 210 and the second limiting groove 220 on the male connector 200 and sets the first limiting protrusion 311 and the second limiting protrusion 321 on the female connector 100, so as to facilitate the machining of the limiting groove and the limiting protrusion and be beneficial to improving the production efficiency.
[0071] Please continue to refer to Figure 6 The male connector 200 of the embodiment of the present application comprises a first connecting section 201, a second connecting section 202 and a third connecting section 203 connected with each other, and the second connecting section 202 is located between the first connecting section 201 and the third connecting section 203. The diameter of the first connecting section 201 is smaller than the diameter of the third connecting section 203, and the diameter of the second connecting section 202 is gradually changed, and gradually increases from the first connecting section 201 to the third connecting section 203.
[0072] The first limiting groove 210 is located on the third connecting section 203, and the second limiting groove 220 extends from the second connecting section 202 to the third connecting section 203.
[0073] The male joint 200 is provided with the above structure, so that the first connecting section 201 with a small diameter can be inserted into the female joint 100, and the first limiting protrusion 311 and the second limiting protrusion 321 can be gradually compressed through the second connecting section 202 with a gradually changing diameter, so that the third connecting section 203 can smoothly enter the female joint 100. The first limiting groove 210 is arranged on the third connecting section 203, and the second limiting groove 220 is arranged on the second connecting section 202 and the third connecting section 203, so as to ensure the stability of the connection between the male joint 200 and the female joint 100, and prevent the male joint 200 from falling off from the female joint 100.
[0074] Further, the first limiting groove 210 of the embodiment of the present application is provided with a chamfer 211, which is located on the side of the first limiting groove 210 away from the insertion direction of the male joint 200.
[0075] The embodiment of the present application is provided with the chamfer 211 on the first limiting groove 210, so that the second limiting protrusion 321 can more smoothly pass through the first limiting groove 210, and the second limiting protrusion 321 is prevented from being clamped into the first limiting groove 210 to cause misassembly.
[0076] Please continue to refer to Figure 8 The embodiment of the present application further includes a first elastic member 310 and a second elastic member 320. The female joint 100 is provided with a first mounting groove 110 and a second mounting groove 120, and the first mounting groove 110 and the second mounting groove 120 are arranged along the circumference of the female joint 100 and are spaced apart along the axial direction of the female joint 100. The first elastic member 310 is located in the first mounting groove 110, and at least part of the first elastic member 310 extends into the receiving channel 1100 after passing through the first mounting groove 110 to form the first limiting protrusion 311. The second elastic member 320 is located in the second mounting groove 120, and at least part of the second elastic member 320 extends into the receiving channel 1100 after passing through the second mounting groove 120 to form the second limiting protrusion 321.
[0077] The embodiment of the present application is provided with the first mounting groove 110 and the second mounting groove 120 on the female joint 100, and the first elastic member 310 and the second elastic member 320 pass through the first mounting groove 110 and the second mounting groove 120 respectively to form the first limiting protrusion 311 and the second limiting protrusion 321, so as to facilitate reducing the manufacturing difficulty of the female joint 100 and reducing the manufacturing cost.
[0078] Further, the first elastic member 310 is in interference fit with the first mounting groove 110, and the second elastic member 320 is in interference fit with the second mounting groove 120. The first elastic member 310 and the second elastic member 320 can be selected as steel wires.
[0079] The first elastic member 310 and the second elastic member 320 are made of steel wire, which is beneficial to reduce the cost and manufacturing difficulty of the first elastic member 310 and the second elastic member 320. The first elastic member 310 is arranged in the first mounting groove 110 and the second elastic member 320 is arranged in the second mounting groove 120 in a manner of interference fit, which is beneficial to ensure the stability of assembly.
[0080] Please continue to refer to Figures 6-10 In the present application, the radial width of the second limiting groove 220 along the joint assembly is D1, the axial length of the second limiting groove 220 along the joint assembly is D2, the axial length of the first limiting groove 210 along the joint assembly is D3, the radial length of the second limiting groove 220 along the joint assembly is D4, the axial length of the first limiting protrusion 311 along the joint assembly is D5, the axial length of the second limiting protrusion 321 along the joint assembly is D6, the radial length of the second limiting protrusion 321 along the joint assembly is D7, and the radial width of the second limiting protrusion 321 along the joint assembly is D8. It can be understood that the radial width of the second limiting groove 220 along the joint assembly is D1, which is substantially equal to the radial width of the second limiting protrusion 321 along the joint assembly, which is D8. The axial length of the first limiting groove 210 along the joint assembly is D3, which is substantially equal to the axial length of the first limiting protrusion 311 along the joint assembly, which is D5.
[0081] To ensure the smooth assembly of the male joint 200 and the female joint 100, the length D6 of the second limiting protrusion 321 along the axial direction of the joint assembly is greater than the length D3 of the first limiting groove 210. Preferably, the axial length D6 of the second limiting protrusion 321 along the joint assembly can be greater than or equal to 1.5 times the axial length D3 of the first limiting groove 210 along the joint assembly.
[0082] In the present application, the length of the second limiting protrusion 321 is set to be greater than the length of the first limiting groove 210, so that when the male joint 200 is inserted into the female joint, the second limiting protrusion 321 is prevented from being clamped into the first limiting groove 210, thereby ensuring that the assembly is in place.
