Description

Technical Field:

[0001] The present invention belongs to the technical field of automotive intake pipe devices, and particularly relates to a new type of intake pipe structure that is resistant to negative pressure and reduces pressure loss. Background Art:

[0002] The existing automotive supercharged intake pipe is arranged according to the position of the air filter. Due to the large size of the air filter, this section of the pipe is generally long, and a mixing valve body for controlling the flow rate needs to be installed in the middle. Considering the assemblability, this section of the pipe cannot be completely connected with hard pipes. Since the middle part of the pipe is relatively soft, it will be sucked flat under negative pressure in the pipe, and it will also increase the pressure loss of the supercharged pipe. Summary of the Invention:

[0003] The purpose of the present invention is: This design uses hard pipes at both ends and a flexible hose in the middle. At the same time, the flexible hose used is not an ordinary rubber hose, and its hardness is between rubber and plastic. The hardness of the housing is enhanced by designing cross ribs on the housing, and it will not affect the installation at the same time. There is no step connection design inside the hard pipe and the flexible hose, which reduces the pressure loss of the pipe and improves the inflation efficiency. The technical solution is as follows:

[0004] A new type of intake pipe structure that is resistant to negative pressure and reduces pressure loss, characterized in that: it includes a plastic hard pipe 1 connecting to the mixing valve end, an intermediate connecting flexible hose 2, and a plastic hard pipe 3 connecting to the supercharger end. The intermediate connecting flexible hose 2 is tightly sealed with the plastic hard pipe 1 connecting to the mixing valve end and the plastic hard pipe 3 connecting to the supercharger end by a clamp 4. Crossed inclined ribs are designed on the outside of the plastic hard pipe 1 connecting to the mixing valve end, the intermediate connecting flexible hose 2, and the plastic hard pipe 3 connecting to the supercharger end. The inner diameter of the pipe gradually decreases from the plastic hard pipe 1 connecting to the mixing valve end to the intermediate connecting flexible hose 2. The internal straight drops of the intermediate connecting flexible hose 2 and the plastic hard pipe 3 connecting to the supercharger end are equal. The inner diameter of the plastic hard pipe 1 connecting to the mixing valve end, the intermediate connecting flexible hose 2, and the plastic hard pipe 3 connecting to the supercharger end is the same as the inner diameter of the intermediate connecting flexible hose 2. The intermediate connecting flexible hose 2 is made of TPV material. Symmetrical clamping grooves are provided at the left and right ends of the outer surface of the intermediate connecting flexible hose 2, and the clamp 4 is inserted into the clamping grooves.

[0005] The beneficial effect of the present invention is: It can effectively solve the problem that the pipe is sucked flat under negative pressure in the intake pipe, and at the same time reduce the pressure loss of the pipe and improve the inflation efficiency. Brief Description of the Drawings:

[0007] Figure 2 It is the cross-sectional view of the intermediate connecting flexible hose 2 of the present invention. Detailed Description of the Invention:

[0008] Reference Figure 1 、 Figure 2 For the novel intake pipe structure with negative pressure resistance and reduced pressure loss, it is characterized in that: it includes a plastic hard pipe 1 connecting to the mixing valve end, an intermediate connecting hose 2, and a plastic hard pipe 3 connecting to the supercharger end. The intermediate connecting hose 2 is tightly sealed with the plastic hard pipe 1 connecting to the mixing valve end and the plastic hard pipe 3 connecting to the supercharger end by a clamp 4. Crossed diagonal ribs are designed on the outer parts of the plastic hard pipe 1 connecting to the mixing valve end, the intermediate connecting hose 2, and the plastic hard pipe 3 connecting to the supercharger end. The inner diameter of the pipe gradually decreases uniformly from the plastic hard pipe 1 connecting to the mixing valve end to the intermediate connecting hose 2. The internal straight drops of the intermediate connecting hose 2 and the plastic hard pipe 3 connecting to the supercharger end are equal. The pipe diameters at the joints of the plastic hard pipe 1 connecting to the mixing valve end, the intermediate connecting hose 2, and the plastic hard pipe 3 connecting to the supercharger end with the inside of the intermediate connecting hose 2 are designed to be the same. The intermediate connecting hose 2 is made of TPV material. Card slots are symmetrically arranged at the left and right ends of the outer surface of the intermediate connecting hose 2, and the clamp 4 is inserted into the card slots.

[0009] During use, fresh air enters the intake pipe from the plastic hard pipe 1 connecting to the mixing valve end, flows through the intermediate connecting hose 2 and the plastic hard pipe 3 connecting to the supercharger end, and then flows into the supercharger end. The pipe diameter gradually decreases uniformly from the connected port 1 of the mixing valve to the intermediate connecting hose 2. The intermediate connecting hose 2 and the plastic hard pipe 3 connecting to the supercharger end have the same diameter design. The change in pipe diameter is minimized throughout the pipeline, which can effectively reduce the pressure loss of the pipeline. The pipe diameters at the joints of the plastic hard pipe 1 connecting to the mixing valve end, the intermediate connecting hose 2, and the plastic hard pipe 3 connecting to the supercharger end with the inside of the intermediate connecting hose 2 are designed to be the same to avoid pressure loss caused by steps. The intake pipe of the supercharger requires the pipe to have a certain negative pressure resistance. The intermediate connecting hose 2 is not an ordinary rubber hose, but a TPV material pipeline with a hardness between that of plastic and rubber. And crossed diagonal ribs are designed on the outer part of the pipeline to enhance the negative pressure resistance of the pipeline.

[0010] The plastic hard pipe 1 connecting to the mixing valve end and the plastic hard pipe 3 connecting to the supercharger end are respectively inserted into the left and right ends of the intermediate connecting hose 2, and the clamp 4 is inserted into and tightened in the card slots on the side surface of the intermediate connecting hose 2, so that the intermediate connecting hose 2 tightly seals the plastic hard pipe 1 connecting to the mixing valve end and the plastic hard pipe 3 connecting to the supercharger end.

[0011] Certainly, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
