[0026] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0027] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0028] One of the preferred embodiments of the present application is as follows: Figures 1 to 9As shown, an automobile engine intake pipe comprises a pipe body 1 and a connecting pipe 2; a connecting block 21 is arranged on at least one side of the connecting pipe 2, the connecting block 21 and the pipe body 1 are matched through a fixing structure 11, and a protective member 12 is arranged inside the pipe body 1; when connecting, the connecting pipe 2 can extend into the pipe body 1 with the connecting block 21, at this time, the connecting block 21 can elastically squeeze the fixing structure 11, so that the fixing structure 11 elastically shrinks, and at this time, the connecting pipe 2 can extend into the pipe body 1 with the connecting block 21 until it fits with the side of the protective member 12, and at this time, the fixing structure 11 just restores its elasticity, and then elastically resets to engage with the side of the connecting block 21, and then the connecting block 21 can be fixed, so that the connecting pipe 2 can be detachably installed in the pipe body 1, which is convenient for better installation and disassembly, and improves the installation and disassembly efficiency. At the same time, the protective member 12 can be used to perform shock absorption, dustproof and moisture-proof treatment on the overall device, so as to better protect the engine, keep the air intake of the intake pipe stable, and ensure the stability of the engine efficiency.

[0029] In this embodiment, Figures 2 to 4 As shown, the fixing structure 11 includes a fixing block 111 installed on the side of the pipe body 1 through a spring, and a fixing groove 112 opened on the side of the connecting block 21; a sliding groove 13 is opened on at least one side of the pipe body 1, and the fixing block 111 slides within the sliding groove 13; when installing, the connecting pipe 2 slides with the connecting block 21 in the sliding groove 13 and elastically squeezes the fixing block 111, so that the connecting pipe 2 can continue to move until it fits with the side of the protective member 12, and then the fixing block 111 restores its elastic reset, so that the fixing block 111 can extend into the connecting pipe 2. The connecting block 21 is inserted into the fixing groove 112 on the side of the connecting block 21, and then engaged to fix the connecting block 21, so that the connecting pipe 2 is firmly connected to the pipe body 1; when disassembling, the fixing block 111 can be pulled, and the fixing block 111 elastically contracts until it is completely extended out of the fixing groove 112. At this time, the connecting pipe 2 can be pulled until the connecting pipe 2 is pulled out of the pipe body 1 for disassembly or replacement of the protective part 12, thereby preventing damage to the intake pipe during disassembly, and thus better installing and disassembling, protecting the intake pipe, keeping the intake of the intake pipe stable, and ensuring the stability of the engine efficiency.

[0030] It is understandable that if Figure 2 and Figure 3 As shown, in order to more stably connect the connecting pipe 2 and the pipe body 1, connecting blocks 21 are provided on both sides of the connecting pipe 2. The two connecting blocks 21 are connected and matched with both sides of the pipe body 1 through a fixed structure 11. The connecting blocks 21 are matched with the sliding groove 13, so two sliding grooves 13 should also be provided. The two sliding grooves 13 are symmetrically arranged on both sides of the pipe body 1.

[0031] In this embodiment, Figure 2 , Figure 5 and Figure 6As shown, it can be understood that in order to enable the connecting pipe 2 to drive the connecting block 21 to smoothly cooperate with the fixed structure 11, the side of the connecting block 21 is set with an inclined slope, and the side of the fixed block 111 is set with an inclined slope, and the inclined surface of the connecting block 21 is in contact with the inclined surface of the fixed block 111; therefore, when the fixed block 111 slides in the sliding groove 13, the fixed block 111 can be smoothly squeezed by the inclined slope, so that the fixed block 111 can be elastically squeezed, so as to better perform the installation and improve the installation efficiency.

[0032] In this embodiment, Figures 5 to 9 As shown, it should be known that in order to remove water from the protective part 12 so that the protective part 12 can repeat noise reduction and water absorption, a spherical retaining bead 113 is arranged in the fixed groove 112, and the inclined surface of the fixed block 111 cooperates with the retaining bead 113, so that the fixed block 111 can be blocked by the retaining bead 113 without external force to prevent the connecting pipe 2 from shaking. When squeezing water, the connecting pipe 2 can be pushed hard at this time, and the connecting pipe 2 can continue to move into the pipe body 1 and squeeze the protective part 12. At this time, the connecting pipe 2 can slide with the connecting block 21, and the sliding of the connecting block 21 can make the fixed groove 112 on the connecting block 21 move. The movement of the fixed groove 112 can make the internal retaining bead 113 squeeze the fixed block 111, so that the connecting pipe 2 can slide, and then squeeze the water from the protective part 12 for repeated use, thereby enhancing the service life of the protective part 12, improving the sustainable use of the protective part 12, and saving resources.

[0033] In this embodiment, Figure 3 As shown, the protective member 12 includes a ring block 121 installed on the side of the pipe body 1, and noise reduction cotton 122 placed on the side of the ring block 121; during installation, the noise reduction cotton 122 can be placed in the pipe body 1 to the side of the ring block 121, and then the connecting pipe 2 is extended into the pipe body 1 and fits with the side of the noise reduction cotton 122, so that the noise reduction cotton 122 can be better limited to prevent the noise reduction cotton 122 from moving, so that the noise reduction and water absorption treatment can be better performed.

[0034] It is understandable that in order to better install the noise reduction cotton 122, the noise reduction cotton 122 can be adhered to the side of the connecting pipe 2 in advance, so that the noise reduction cotton 122 can be taken out and replaced more quickly, thereby improving maintenance efficiency.

[0035] In this embodiment, Figure 1 and Figure 2 As shown, it should be known that the connecting pipe 2 is divided into a straight section and a tapered section. The straight section can be inserted into the pipe body 1 to cooperate with the protective piece 12, and the tapered section can prevent the straight section from extending too far into the pipe body 1 and squeezing the protective piece 12 too much, thereby better protecting the protective piece 12 and extending the service life of the protective piece 12.

[0036] In this embodiment, Figures 8 to 9 As shown, it should be known that when the protective member 12 is squeezed for reuse, in order to discharge the moisture absorbed by the noise reduction cotton 122, a drainage hole 22 is opened on at least one side of the straight section of the connecting pipe 2, and an outflow hole 14 is opened on the side of the tube body 1, and the drainage hole 22 cooperates with the outflow hole 14; when the connecting pipe 2 and the tube body 1 are normally connected, the retaining bead 113 in the connecting block 21 on the connecting pipe 2 squeezes the fixing block 111 to elastically contract, and the drainage hole 22 on the connecting pipe 2 is misaligned with the outflow hole 14 of the tube body 1, and the connecting pipe 2 can block the outflow hole 14; when the protective member 12 is squeezed for reuse, the connecting pipe 2 slides toward the inside of the tube body 1, thereby making the connecting pipe 2 coincides with the outflow hole 14 of the tube body 1, at this time, the water in the noise reduction cotton 122 is squeezed out by the connecting tube 2, and then flows into the drainage hole 22 through the connecting tube 2, and then flows out of the tube body 1 through the outflow hole 14; when the water is squeezed out, the connecting tube 2 is released, the squeezed fixing block 111 on the connecting tube 2 is elastically reset, and then the blocking bead 113 is squeezed, and the blocking bead 113 cooperates with the inclined surface of the fixing block 111, and then moves away from the axial direction of the tube body 1, so that the drainage hole 22 on the connecting tube 2 is misaligned with the outflow hole 14, until the fixing block 111 does not squeeze the blocking bead 113, the fixing block 111 and the side of the fixing groove 112 fit together, and at this time the connecting tube 2 can just cover the outflow hole 14.

[0037] In this embodiment, Figure 1 and Figure 3 As shown, it should be known that a filter 23 is provided in the conical section of the connecting pipe 2, and the debris in the air can be filtered through the filter 23, so that the protective member 12 can be better protected so as to stably inhale air to maintain stable power.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application.
