[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5An air delivery hose assembly structure of an air intake system includes a first hose 1 and a second hose 3. A connector 2 is provided between the first hose 1 and the second hose 3. The connector 2 includes a hard tube 21 and a clamp 24. A partition 22 is provided in the middle of the hard tube 21. A connecting portion 23 is provided on each side of the partition 22. The first hose 1 and the second hose 3 are fixed to the connecting portion 23 by the clamp 24. During assembly, the operator sleeves the facing ends of the first hose 1 and the second hose 3 on the connecting portion 23 of the hard tube 21 in the connector 2, and contacts the partition 22 to ensure that the first hose 1 and the second hose 3 are accurately connected to the connector 2. At the same time, anti-slip ribs are provided at both ends of the hard tube 21 to enhance the friction between the hard tube 21 and the first hose 1 and the second hose 3, and improve the connection strength between the first hose 1 and the second hose 3 and the hard tube 21. Then, the operator uses the clamp 24 to firmly fix the first hose 1 and the second hose 3 to the hard tube 21, and the air delivery hose is completed. For the assembly of the pipes, the clamp 24 can be an existing single-ear stepless clamp, which can reduce material costs, but is not limited to this. The first hose 1 and the second hose 3 are both made of vulcanization process and have a wall thickness of 5 mm, and the first hose 1 is made of NBR+PVC material, and the second hose 3 is made of ACM material. The hard pipe 21 is made of injection molding process and has a wall thickness of 3 mm, and the hard pipe is made of PA6+GF30 material, which is heat-resistant and oil-resistant and increases the rigidity of the pipeline. It has low cost and simple assembly, which is convenient for operators to assemble in batches quickly and improves assembly efficiency, which not only meets installation requirements but also reduces costs.

[0021] In some embodiments, the first hose 1 and the second hose 3 are both provided with positioning grooves 4 at the facing ends, and protrusions 5 are provided at both sides of the partition 22. When the operator connects the first hose 1 and the second hose 3 through the connector 2, the positioning grooves 4 on the first hose 1 and the second hose 3 are adapted and positioned with the protrusions 5 on both sides of the partition 22, so that the first hose 1 and the second hose 3 are accurately sleeved on the connecting portion 23 in the connector 2, ensuring that the first hose 1 and the second hose 3 are accurately and seamlessly connected to the connector 2, thereby improving the accuracy of installation.

[0022] In some embodiments, the clamp 24 is an existing bolt-connected clamp that can be recycled, so that when the operator performs maintenance and cleaning on the gas hose, he only needs to remove the clamp 24 at the second hose 3 to remove the second hose 3. The operator can then perform maintenance and cleaning on the second hose 3 and the first hose 1 without removing the entire gas hose, which facilitates disassembly and assembly and saves time and effort.

[0023] In some embodiments, a connection block 11 is provided at one end of the first hose 1 away from the connector 2, and a connection groove 31 is provided at one end of the second hose 3 away from the connector 2. The connection block 11 and the connection groove 31 can facilitate operators to identify the first hose 1 and the second hose 3 when installing the gas hose, and the structure is simple and the cost is low.

[0024] In some embodiments, the outer surface of the first hose 1 is provided with a wire hole 12. The wire hole 12 can facilitate wiring in the vehicle, and avoid the installation of the gas hose affecting the wiring in the vehicle, resulting in a lot of effort and cost to change the layout in the vehicle, affecting the processing and assembly efficiency of the vehicle.

[0025] In some embodiments, a corrugated portion 13 is provided on the first hose 1 near the connector 2. The corrugated portion 13 enables the first hose 1 to have a telescopic function, which can greatly reduce or even block the transmission of the engine's own vibration to the vehicle body, thereby improving the driving comfort.

[0026] In some embodiments, reinforcing ribs are provided on the pipelines of the first hose 1 and the second hose 3. The reinforcing ribs on the pipelines of the first hose 1 and the second hose 3 can improve the overall rigidity of the first hose 1 and the second hose 3, and prevent the first hose 1 and the second hose 3 from increasing negative pressure and shrinking the pipelines when the car accelerates with a large throttle, thereby improving driving safety.

[0027] In some embodiments, a branch pipe 32 is provided on the side of the second hose 3. The operator can connect other pipes through the branch pipe 32, which can be a PVC pipe, but is not limited thereto, thereby increasing the transmission path of the hose assembly and improving the transmission efficiency.

[0028] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
