Description

Technical Field

[0001] This utility model relates to a clean pipe connection device and an automobile containing the same. Background Technology

[0002] Various automotive components require assembly through various structures to complete the assembly of a complete vehicle. Therefore, corresponding connectors need to be designed for different structures to connect the corresponding components, especially the connection between clean pipes and the automotive engine. Currently, a single-ear stepless clamp structure is used to connect clean pipes and automotive engine piping. During assembly, a clamp is fitted onto the outer circumference of the pipe connection port. The connector is inserted into the pipe connection port and then clamped with the clamp to connect the clean pipe to the automotive engine piping. However, this results in cumbersome assembly operations, long assembly time, complex structure, and high cost. Utility Model Content

[0036] The following description of the embodiments is with reference to the accompanying drawings, which illustrate specific embodiments in which the present invention can be implemented.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment discloses a clean pipe connection device, which includes an engine pipe 1 and a clean pipe body 2. The engine pipe 1 includes a pipe body 11 and an installation pipe 12. One end of the installation pipe 12 is connected to the outer surface of the pipe body 11 and communicates with the pipe body 11. The other end of the installation pipe 12 extends outward and protrudes. The clean pipe body 2 includes a connecting pipe 21, a blocking member 22, and a sleeve 23. The blocking member 22 is connected to the outer peripheral surface of the connecting pipe 21. The sleeve 23 is connected to the side of the blocking member 22 facing the installation pipe 12 and is inserted into the installation pipe 12 and snapped together with the inner wall surface of the installation pipe 12. The outer peripheral surface of the sleeve 23 is press-fitted with the inner wall surface of the installation pipe 12. The end of the installation pipe 12 away from the pipe body 11 abuts against the blocking member 22. The sleeve 23 is sleeved on the connecting pipe 21 and has a clearance space 24 between it and the outer peripheral surface of the connecting pipe 21.

[0038] When the clean pipe body 2 and the engine pipe 1 are connected, the clean pipe body 2 is inserted into the mounting pipe 12 of the engine pipe 1 through the sleeve 23. Since the sleeve 23 is fitted onto the connecting pipe 21 and has a clearance space 24 between it and the outer circumferential surface of the connecting pipe 21, the sleeve 23 can be easily inserted into the mounting pipe 12 and snap-fitted to the inner wall of the mounting pipe 12. Furthermore, the outer circumferential surface of the sleeve 23 and the inner wall of the mounting pipe 12 have an interference fit. This interference fit and snap-fit ​​connection replace the original single-ear stepless clamp structure, making assembly very convenient and simplifying the overall structure. This not only reduces costs but also decreases the number of processes and significantly shortens assembly time, saving labor. Simultaneously, during assembly, the blocking member 22 abuts against the end of the mounting pipe 12, ensuring that the clean pipe body 2 and the engine pipe 1 are properly assembled and snap-fitted, achieving precise installation and further shortening assembly time, saving labor.

[0039] In this embodiment, the outer periphery of the bottom end of the sleeve 23 away from the blocking member 22 has a snap-fit ​​portion 231, which snaps onto the inner wall of the mounting tube 12. The outer periphery of the sleeve 23 is snapped onto the inner wall of the mounting tube 12 via the snap-fit ​​portion 231, ensuring a secure snap-fit ​​connection between the sleeve 23 and the mounting tube 12, thereby improving the safety and stability of the clean tube connection device.

[0040] The snap-fit ​​part 231 has an inclined guide surface 232 on the side facing away from the blocking member 22. The inclined guide surface 232 has a guiding function, so that during the mutual insertion between the sleeve 23 and the mounting tube 12, the mounting tube 12 abuts against the inclined guide surface 232 and slides on the inclined guide surface 232. The inclined guide surface 232 also ensures that the sleeve 23 can be smoothly inserted into the mounting tube 12 and connected to the mounting tube 12, which has high stability and is very convenient to use.

[0041] The inner wall of the mounting pipe 12 has a stepped portion 121 at one end near the pipe body 11. The diameter of the side of the stepped portion 121 facing the pipe body 11 is larger than the diameter of the other side of the stepped portion 121 facing away from the pipe body 11. A snap-fit ​​portion 231 is snap-fitted onto the stepped portion 121. The stepped portion 121, located at the end of the inner wall of the mounting pipe 12 near the pipe body 11, results in a large interference fit area between the inner wall of the mounting pipe 12 and the outer circumferential surface of the sleeve 23, effectively strengthening the connection between the clean pipe body 2 and the engine pipe 1 for greater stability and reliability. Simultaneously, the snap-fit ​​portion 231, snap-fitted onto the stepped portion 121, further enhances the stability and reliability of the connection between the snap-fit ​​portion 231 and the stepped portion 121, improving the safety and stability of the clean pipe connection device. Furthermore, the snap-fit ​​portion 231 and the stepped portion 121 have simple structures and are easy to manufacture.

[0042] The mounting pipe 12 includes a mounting portion 122 and a contraction portion 123. The two ends of the mounting portion 122 are connected to the outer peripheral surface of the pipe body 11 and the contraction portion 123, respectively. A stepped portion 121 is located on the inner wall surface of the mounting portion 122. The outer diameter of the contraction portion 123 is smaller than the outer diameter of the mounting portion 122. The structural strength of the mounting portion 122 is higher than that of the contraction portion 123. By placing the stepped portion 121 within the mounting portion 122 and connecting the snap-fit ​​portion 231 to the mounting portion 122, high overall structural connection stability is achieved.

[0043] In this embodiment, the blocking member 22 is annular in shape, with its outer edges away from the connecting pipe 21 protruding from the outer surface of the sleeve 23 and abutting against the end of the mounting pipe 12. All four sides of the blocking member 22 abut against the end of the mounting pipe 12, ensuring proper assembly and snap-fit ​​connection between the clean pipe body 2 and the engine pipe 1, achieving precise installation. Furthermore, the structure is simple and easy to manufacture.

[0044] The connecting pipe 21 passes through the blocking member 22 and extends into the sleeve 23. The sleeve 23 is connected to the engine pipeline 1, and the extension of the connecting pipe 21 into the sleeve 23 facilitates communication with the engine pipeline 1, allowing for easy flow between the engine pipeline 1 and the clean pipe body 2. Preferably, the end of the connecting pipe 21 protrudes from the sleeve 23 at the end away from the blocking member 22.

[0045] This embodiment also discloses a vehicle that includes the clean pipe connection device as described above.

[0046] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
