[0061] The following is a detailed description of the pipe connection structure of the embodiment of the present application in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can complement or combine with each other. Figure 1 A three-dimensional exploded view of a pipe connection structure provided in one embodiment of the present application; Figure 2 for Figure 1 A cross-sectional view of the pipe connection structure shown is taken along a direction parallel to the axis of the first joint; Figure 3 for Figure 1 A cross-sectional view of the pipe connection structure shown is taken along a direction perpendicular to the axis of the first joint; Figure 4 for Figure 1 A schematic diagram of the three-dimensional structure of the clamping ring of the pipeline connection structure shown; Figure 5 for Figure 1 A cross-sectional view of the body of the first joint shown is taken along a direction perpendicular to the axis of the first joint; Figure 6 for Figure 1 A side view of the second joint is shown.

[0062] See also Figure 1 and Figure 2An embodiment of the present application provides a pipeline connection structure 100, which includes a first joint 10 and a second joint 20, wherein the first joint 10 and the second joint 20 are hollow structures.

[0063] The first joint 10 includes a first segment 111 and a second segment 112 connected to the first segment 111. The second joint 20 includes a third segment 21 and a fourth segment 22 connected to the third segment 21. The third segment 21 is disposed within the first segment 111, and the fourth segment 22 is partially disposed within the second segment 112. The second joint 20 can deflect relative to the axis of the first joint 10 within the first joint 10, thereby causing the third segment 21 to deflect relative to the axis of the first joint 10 within the first segment 111, and the fourth segment 22 to deflect relative to the axis of the first joint 10 within the second segment 112. The second joint 20 and the first joint 10 can move relative to each other along the axis of the first joint 10, and when the third segment 21 and the second segment 112 approach each other along the axis of the first joint 10, the third segment 21 and the second segment 112 abut against each other.

[0064] In the pipe connector 100 provided in this embodiment of the present application, the fourth segment 22 is partially disposed within the second segment 112, with the remaining portion exposed from the second segment 112. The portion exposed from the second segment 112 can be used to connect to a pipeline. To connect two pipeline sections, the free end of the first segment 111 of the first connector 10 is connected to one end of the pipeline, and the free end of the fourth segment 22 of the second connector 20 is connected to the other end of the pipeline. Thus, the pipe connector 100 can connect the two pipeline sections.

[0065] In the pipe connection structure 100 provided by the embodiment of the present application, the second joint 20 can be deflected relative to the axis of the first joint 10 in the first joint 10, so that the third segment 21 is deflected relative to the axis of the first joint 10 in the first segment 111, and the fourth segment 22 is deflected relative to the axis of the first joint 10 in the second segment 112. Therefore, the two pipes connected to the pipe connection structure 100 can be deflected to a certain extent, so that when the pipe connection structure 100 is used in the engine pipe, the engine pipe can be deflected. Different pipe sections of the pipeline can be deflected relative to each other; since the second joint 20 and the first joint 10 can move relative to each other along the axis of the first joint 10, and the third segment 21 and the second segment 112 are close to each other along the axis of the first joint 10, the third segment 21 and the second segment 112 are abutted against each other, then the two pipelines connected to the two ends of the pipeline connection structure 100 can be stretched and retracted along the axis of the first joint 10, and the two pipelines will not be separated when stretched. Therefore, when the pipeline connection structure 100 is used in the engine pipeline, the engine pipeline can be stretched and retracted without being separated.

[0066] Among them, the second joint 20 can be deflected relative to the axis of the first joint 10 in the first joint 10, which means that the second joint 20 can be deflected at a certain angle relative to the axis of the first joint 10, that is, before the second joint 20 is deflected relative to the axis of the first joint 10, the axis of the first joint 10 and the axis of the second joint 20 coincide with or are parallel to each other, and after the second joint 20 is deflected relative to the axis of the first joint 10, there is a certain angle between the axis of the first joint 10 and the axis of the second joint 20; the deflection of the second joint 20 relative to the axis of the first joint 10 can be along multiple directions, for example, the second joint 20 can be deflected relative to the axis of the first joint 10 to any circumferential direction of the axis.

[0067] The second joint 20 deflects relative to the axis of the first joint 10. This can be done while the first joint 10 remains stationary and the second joint 20 deflects, while the second joint 20 remains stationary and the first joint 10 deflects, or while the first joint 10 and the second joint 20 deflect simultaneously. The second joint 20 and the first joint 10 can move relative to each other along the axis of the first joint 10. This can be done while the first joint 10 remains stationary and the second joint 20 moves, while the second joint 20 remains stationary and the first joint 10 moves, or while the first joint 10 and the second joint 20 move simultaneously.

[0068] In one embodiment, the circumferential dimensions of the inner wall of the first segment 111 are the same at all locations, the peripheral dimensions of the fourth segment 22 are the same at all locations, the peripheral dimensions of the third segment 21 may not be all the same, and the circumferential dimensions of the inner wall of the second segment 112 are not all the same. The circumferential dimension of the inner wall of the first segment 111 may be larger than the maximum peripheral dimension of the third segment 21, so that there is a gap between the inner wall of the first segment 111 and the outer wall of the third segment 21, so that the first segment 111 can be deflected relative to the axis of the first joint 10 in the third segment 21, and the first segment 111 and the third segment 21 can move relative to each other along the axis of the first joint 10. The minimum circumferential dimension of the inner wall of the second segment 112 may be greater than the outer dimension of the fourth segment 22. Thus, a gap exists between the inner wall of the second segment 112 and the outer wall of the fourth segment 22, thereby allowing the second segment 112 to deflect within the fourth segment 22 relative to the axis of the first joint 10, and the second segment 112 and the fourth segment 22 to move relative to each other along the axis of the first joint 10. The maximum outer dimension of the third segment 21 is greater than the minimum circumferential dimension of the inner wall of the second segment 112. This allows the third segment 21 and the second segment 112 to abut against each other when they approach each other along the axis of the first joint 10.

[0069] Among them, when the cross-section of the first segment 111 perpendicular to its axis is a circular ring, the circumferential dimension of the inner wall of the first segment 111 refers to its inner diameter; when the cross-section of the fourth segment 22 perpendicular to its axis is a circular ring, the outer dimension of the fourth segment 22 refers to its outer diameter; when the cross-section of each part of the second segment 112 perpendicular to its axis is a circular ring, the minimum circumferential dimension of the inner wall of the second segment 112 refers to the minimum value of the corresponding inner diameter at each part, or, when the inner wall of the second segment 112 is composed of multiple arcs, the minimum circumferential dimension of the inner wall of the second segment 112 may refer to the minimum value of the inner diameter of the circle in which the arcs corresponding to each part of the second segment 112 are located; when the cross-section of each part of the third segment 21 perpendicular to its axis is a circular ring, the maximum outer dimension of the third segment 21 refers to the maximum value of the outer diameter at each part.

[0070] In one embodiment, the first connector 10 includes a body 11 and a snap ring 12. The body 11 includes a first portion and a second portion 113 connected to the first portion. A through groove 1121 is provided on the wall of the second portion 113. The snap ring 12 is fixedly disposed in the through groove 1121, and the inner wall of the snap ring 12 protrudes inward relative to the inner wall of the second portion 113. The first segment 111 includes the first portion, and the second segment 112 includes the second portion 113 and the snap ring 12. With this arrangement, the inner wall of the snap ring 12 is minimized at the point where the inner wall of the second segment 112 has its smallest circumferential dimension. When the third segment 21 and the second segment 112 approach each other along the axis of the first connector 10, the third segment 21 can abut against the snap ring 12. Furthermore, when manufacturing the first joint 10, the inner diameters of the first and second portions 113 can be made identical. By providing a through groove 1121 in the second portion 113 and placing a retaining ring 12 within the through groove 1121, the minimum circumferential dimension of the inner wall of the second segment 112 can be made smaller than the maximum outer dimension of the third segment 21. This facilitates the manufacture of the first joint 10 and simplifies the manufacturing process. The first segment 111 of the first joint 10 can comprise only the first portion. The inner diameter of the ring formed by the inner wall of the retaining ring 12 is equal to the minimum circumferential dimension of the inner wall of the second segment 112.

[0071] In one embodiment, the snap ring 12 is detachably connected to the second portion 113 of the first connector 10. With this arrangement, when assembling the first connector 10 and the second connector 20, the third segment 21 can be first pushed into the first segment 111, and then the snap ring 12 can be installed into the through groove 1121 to secure the snap ring 12 therein. When disassembling the first connector 10 and the second connector 20, the snap ring 12 is first removed, and then the first connector 10 is removed from the second connector 20. Therefore, the detachable connection between the snap ring 12 and the second portion 113 of the first connector 10 facilitates assembly and disassembly of the first connector 10 and the second connector 20. Alternatively, the snap ring 12 and the second portion 113 can be non-detachably connected.

[0072] In one embodiment, see Figure 3 and Figure 4 The snap ring 12 is provided with a snap protrusion 123 at each end, and the second portion 113 is provided with a limiting groove 1122 that communicates with the through groove 1121. When the snap ring 12 is connected to the second portion 113, the snap protrusion 123 enters the limiting groove 1122 and abuts against the inner wall of the limiting groove 1122. The snap protrusion 123 enters the limiting groove 1122 and abuts against the inner wall of the limiting groove 1122, which can make the connection between the snap ring 12 and the second portion 113 more secure. After the snap protrusion 123 is removed from the limiting groove 1122, the snap ring 12 and the second portion 113 can be separated, facilitating assembly and disassembly of the snap ring 12 and the second portion 113.

[0073] The snap protrusion 123 can be formed by the end of the snap ring 12 protruding outward. When the snap ring 12 is pushed into the through groove 1121, the two ends of the snap ring 12 shrink inward, and the snap protrusion 123 can enter the second part 113 through the through groove 1121, and enter the limiting groove 1122 along the inner wall of the second part 113; after the snap protrusion 123 is aligned with the limiting groove 1122, the two ends of the snap ring 12 extend outward, the snap protrusion 123 enters the limiting groove 1122, and the snap protrusion 123 is abutted against the wall of the limiting groove 1122 close to the snap protrusion 123, so that the snap ring 12 is firmly connected to the second part 113. When removing the snap ring 12 from the second portion 123 , the two ends of the snap ring 12 are retracted inward, the buckle protrusion 123 is disengaged from the limiting groove 1122 , and the snap ring 12 is pulled outward to remove the snap ring 12 from the second portion 113 .

[0074] Among them, see Figure 5 A protrusion 1123 is provided between the through groove 1121 and the limiting groove 1122. The wall of the protrusion 1123 facing the limiting groove 1122 is the wall where the limiting groove 1122 and the buckle protrusion 123 abut against each other. The limiting groove 1122 and the through groove 1121 are connected through the inner cavity of the second portion 113.

[0075] In one embodiment, the snap ring 12 may be arc-shaped, and the number of the snap rings 12 may be two or more. The second portion 113 is provided with through grooves 1121 corresponding to the snap rings 12, and each through groove 1121 of the second portion 113 is provided with limiting grooves 1122 at both ends. Figure 3 A retaining groove 1122 may be provided between two adjacent through grooves 1121. When the snap ring 12 is installed in the second portion 113, the two adjacent snap protrusions 123 of the two snap rings 12 may share the retaining groove 1122. When there are two or more snap rings 12, the size of each snap ring 12 can be made smaller to facilitate connection between the snap ring 12 and the second portion 113. Furthermore, when two or more snap rings 12 are connected to the second portion 113, the first connector 10 and the second connector 20 can be prevented from detaching.

[0076] in, Figure 3 Taking two snap rings 12 as an example, when there are two snap rings 12, only two through-slots 1121 are required on the second portion 113, simplifying the structural complexity of the second portion 113. In other embodiments, the number of snap rings 12 may include three, four, or more. The two or more snap rings 12 may have the same size and structure, allowing them to be manufactured using a common mold, reducing production costs.

[0077] In one embodiment, see again Figure 4 The clasp 12 may include a clasp body 121 and connecting portions 122 extending from both ends of the clasp body 121. The free ends of the connecting portions 122 protrude outward to form the snap protrusions 123. The thickness of the connecting portion 122 is less than that of the clasp body 121. The thickness of the connecting portion 122 refers to the dimension perpendicular to the extension direction of the clasp 12. Since the thickness of the clasp body 121 is greater than that of the connecting portion 122, the clasp body 121 is more secure and less likely to break. By making the connecting portion 122 thinner than the clasp body 121, the elasticity of the connecting portion 122 is increased, making it more likely to deform and contract inward, thereby allowing the snap protrusions 123 on the connecting portion 122 to more easily enter the retaining grooves 1122. In other embodiments, the thickness of the connecting portion 122 may be equal to or slightly greater than the thickness of the clasp body 121.

[0078] Furthermore, each end of the snap ring body 121 may include two connecting portions 122, each end of which is provided with a snap protrusion 123. The two connecting portions 122 may be arranged along the thickness direction of the snap ring 12, and each end of the through-slot 1121 of the second portion 113 is provided with two limiting grooves 1122 that correspond one-to-one with the two snap protrusions 123 of each connecting portion 122. With this arrangement, when the snap ring 12 is connected to the second portion 113, the two snap protrusions 123 at each end of the snap ring 12 respectively enter the corresponding limiting grooves 1122, which can ensure a more secure connection between the snap ring 12 and the second portion 113.

[0079] A notch 124 may be provided at each end of the snap ring 12, separating the connecting portion 122 from the snap ring body 121 in a direction parallel to the extension of the connecting portion 122. This configuration allows the connecting portion 122 to have a smaller dimension perpendicular to its extension direction and perpendicular to its thickness, thereby making it easier for the connecting portion 122 to retract inward.

[0080] In one embodiment, see again Figure 3 and Figure 4 A groove 1213 is provided on the inner wall of the snap ring 12, and a limiting block 1125 is provided in the through groove 1121. When the snap ring 12 is connected to the second portion 113, the limiting block 1125 cooperates with the groove 1213. When the snap ring 12 is pushed into the groove 1213, the inner wall of the groove 1213 abuts against the limiting block 1125. The cooperation between the groove 1213 and the limiting protrusion 1125 prevents the snap ring 12 from further entering the interior of the second portion 113, thereby making the connection between the snap ring 12 and the second portion 113 more secure.

[0081] In one embodiment, see again Figure 5 The second portion 113 located on both sides of the through slot 1121 is provided with reinforcing ribs 1126, and the portions of the through slot 1121 located on both sides are connected by protrusions 1123, limit blocks 1125 and reinforcing ribs 1126. The reinforcing ribs 1126 can play a role in strengthening the first joint 10.

[0082] Furthermore, when the snap ring 12 is connected to the second portion 113 , the notch 124 of the snap ring 12 is located outside the reinforcing rib 1126 , which can also prevent the snap ring 12 from further entering the second portion 113 .

[0083] In one embodiment, see again Figure 2The inner wall of the clamping ring 12 includes a first wall surface 1211 and a second wall surface 1212 adjacent to the first wall surface 1211. The first wall surface 1211 is closer to the first segment 111 than the second wall surface 1212. The first wall surface 1211 extends outwardly from the end connected to the second wall surface 1212 to the end away from the second wall surface 1212. Figure 2 and Figure 6 The outer wall of the third segment 21 includes a third wall surface 211 and a fourth wall surface 212 adjacent to the third wall surface 211. The fourth wall surface 212 is closer to the fourth segment 22 than the third wall surface 211. The fourth wall surface 212 extends obliquely inward from the end connected to the third wall surface 211 to the end facing away from the third wall surface 211. When the third segment 21 abuts against the second segment 112, the third wall surface 211 abuts against the first wall surface 1211. That is, at least a portion of the third wall surface 211 abuts against the first wall surface 1211, thereby preventing the third segment 21 from separating from the second segment 112 and making the connection between the third segment 21 and the second segment 112 more secure.

[0084] In one embodiment, an annular groove 213 is defined on the outer wall of the third segment 21. A sealing member 30 is disposed within the annular groove 213, abutting against the walls of the annular groove 213 and the inner wall of the first segment 111, respectively. The sealing member 30 improves the seal between the first connector 10 and the second connector 20, preventing leakage of substances within the pipeline connected to the pipeline connector 100. The sealing member 30 may be an elastic sealing ring, such as a rubber sealing ring, which has high elasticity. When the first connector 10 and the second connector 20 deflect, the elastic sealing ring always abuts against the walls of the annular groove 213 and the inner wall of the first segment 111. The thickness of the sealing member 30 can be determined based on the gap between the first segment 111 and the third segment 21. Generally, the thickness of the sealing member 30 is slightly greater than the gap between the first segment 111 and the third segment 21, ensuring a good seal between the first connector 10 and the second connector 20 even when they deflect relative to each other. The annular groove 213 may be provided on the third wall surface 211 .

[0085] An embodiment of the present application further provides an engine pipeline, which includes the above-mentioned pipeline connection structure 100.

[0086] The transmitter pipeline may further include two sections of pipeline, and the two sections of pipeline are respectively connected to the two free ends of the pipeline connection structure 100.

[0087] The engine pipeline provided by the embodiment of the present application has a pipeline connection structure 100, in which the second joint 20 can be deflected relative to the axis of the first joint 10 in the first joint 10, thereby causing the third segment 21 to be deflected relative to the axis of the first joint 10 in the first segment 111, and the fourth segment 22 to be deflected relative to the axis of the first joint 10 in the second segment 112. Therefore, the two pipelines connected to the pipeline connection structure 100 can be deflected to a certain extent, so that the pipeline connection structure 100 can be used in the engine pipeline. As a result, different sections of the engine pipeline can be deflected relative to each other; since the second joint 20 and the first joint 10 can move relative to each other along the axis of the first joint 10, and the third segment 21 and the second segment 112 are close to each other along the axis of the first joint 10, the third segment 21 and the second segment 112 are abutted against each other, the two pipelines connected to the two ends of the pipeline connection structure can be stretched and retracted along the axis of the first joint 10, and the two pipelines will not be detached when stretched, so that when the pipeline connection structure 100 is used in the engine pipeline, the engine pipeline can be stretched and retracted and will not be detached.

[0088] An embodiment of the present application also provides a vehicle, which includes the above-mentioned engine pipeline.

[0089] In the vehicle provided by the embodiment of the present application, the second joint 20 of the pipeline connection structure 100 in the engine pipeline can be deflected relative to the axis of the first joint 10 in the first joint 10, so that the third segment 21 is deflected relative to the axis of the first joint 10 in the first segment 111, and the fourth segment 22 is deflected relative to the axis of the first joint 10 in the second segment 112. Therefore, the two pipelines connected to the pipeline connection structure 100 can be deflected to a certain extent, so that when the pipeline connection structure 100 is used in the engine pipeline This allows different sections of the engine pipeline to deflect relative to each other; since the second joint 20 and the first joint 10 can move relative to each other along the axis of the first joint 10, and the third segment 21 and the second segment 112 are close to each other along the axis of the first joint 10, the third segment 21 and the second segment 112 are abutted against each other, and the two pipelines connected to the two ends of the pipeline connection structure can be stretched and retracted along the axis of the first joint 10, and the two pipelines will not be detached when stretched, so that when the pipeline connection structure 100 is used in the engine pipeline, the engine pipeline can be stretched and retracted and will not be detached.
