Description

Technical fields:

[0001] This utility model belongs to the technical field of automotive intake pipe equipment, specifically relating to a novel intake pipe structure that is resistant to negative pressure and reduces pressure loss. Background technology:

[0002] The existing automotive turbocharger intake pipe is arranged according to the location of the air filter. Because the air filter is relatively large, this section of pipe is generally quite long. A mixing valve body to control the flow rate must also be installed in the middle. Considering the ease of assembly, this section of pipe cannot be completely connected with rigid pipe. Because the pipe in the middle is relatively soft, it will be sucked down under negative pressure, which will also increase the pressure loss of the booster pipe. Utility Model Content:

[0003] The purpose of this utility model is as follows: This design uses rigid pipes at both ends and a flexible hose in the middle for connection. The hose is not made of ordinary rubber; its hardness is between that of rubber and plastic. Cross ribs are added to the shell to enhance its rigidity without affecting installation. The rigid pipe and flexible hose have a stepless connection design inside, reducing pressure loss and improving inflation efficiency. The technical solution is as follows:

[0004] A novel intake pipe structure with negative pressure resistance and reduced pressure loss is characterized by: a plastic rigid pipe 1 connecting to a mixing valve end, an intermediate connecting hose 2, and a plastic rigid pipe 3 connecting to a booster end. The intermediate connecting hose 2 is clamped and sealed with the plastic rigid pipes 1 and 3. The plastic rigid pipes 1, 2, and 3 are externally designed with intersecting diagonal ribs. The inner diameter of the pipes from the plastic rigid pipe 1 to the intermediate connecting hose 2 decreases uniformly. The internal diameter of the intermediate connecting hose 2 and the plastic rigid pipe 3 is equal. The internal diameter of the plastic rigid pipe 1, intermediate connecting hose 2, and booster end plastic rigid pipe 3 is the same as that of the intermediate connecting hose 2. The intermediate connecting hose 2 is made of TPV material. The outer surface of the intermediate connecting hose 2 has symmetrical grooves at both ends, and the clamp 4 is inserted into the grooves.

[0005] The beneficial effects of this utility model are: it can effectively solve the problem of the air intake pipe being sucked down under negative pressure, while reducing the pressure loss of the pipe and improving the inflation efficiency. Attached image description:

[0007] Figure 2 This is a cross-sectional view of the intermediate connecting hose 2 of this utility model. Detailed implementation method:

[0008] Reference Figure 1 , Figure 2 The novel intake pipe structure, characterized by its resistance to negative pressure and reduced pressure loss, is as follows: it includes a plastic rigid pipe 1 connecting to the mixing valve end, an intermediate connecting hose 2, and a plastic rigid pipe 3 connecting to the booster end. The intermediate connecting hose 2 is clamped and sealed with the plastic rigid pipes 1 and 3. The plastic rigid pipes 1, 2, and 3 are externally designed with intersecting diagonal ribs. The inner diameter of the pipes from the plastic rigid pipe 1 to the intermediate connecting hose 2 decreases uniformly. The internal drop-off of the intermediate connecting hose 2 and the plastic rigid pipe 3 is equal. The pipe diameter at the joint between the plastic rigid pipe 1, the intermediate connecting hose 2, and the plastic rigid pipe 3 and the intermediate connecting hose 2 is designed to be the same. The intermediate connecting hose 2 is made of TPV material. The outer surface of the intermediate connecting hose 2 has symmetrical grooves at both ends, and the clamp 4 is inserted into the grooves.

[0009] During use, fresh air enters the intake pipe from the plastic rigid tube 1 connecting to the mixing valve, flows through the intermediate connecting hose 2 and the plastic rigid tube 3 connecting to the booster, and flows into the booster. The pipe diameter decreases uniformly from the mixing valve connection port 1 to the intermediate connecting hose 2. The intermediate connecting hose 2 and the plastic rigid tube 3 connecting to the booster are designed with equal diameters to minimize pipe diameter changes throughout the pipeline, thus effectively reducing pipeline pressure loss. The pipe diameters at the joints between the plastic rigid tube 1 connecting to the mixing valve, the intermediate connecting hose 2, and the plastic rigid tube 3 connecting to the booster are the same as those at the intermediate connecting hose 2, avoiding pressure loss caused by steps. The booster intake pipeline requires the pipe to have a certain negative pressure resistance. The intermediate connecting hose 2 is not made of ordinary rubber hose, but is made of TPV material with a hardness between plastic and rubber, and the pipeline is designed with intersecting diagonal ribs on the outside to enhance the pipeline's negative pressure resistance.

[0010] The left and right ends of the intermediate connecting hose 2 are respectively fitted with plastic hard tube 1 connecting the mixing valve end and plastic hard tube 3 connecting the booster end, and the clamp 4 is inserted into the groove on the side surface of the intermediate connecting hose 2 and tightened, so that the intermediate connecting hose 2 presses and seals the plastic hard tube 1 connecting the mixing valve end and the plastic hard tube 3 connecting the booster end.

[0011] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
