Description

Technical Field

[0001] The utility model relates to the technical field of air filter intake pipes for automobile engines, in particular to an air filter intake pipe for off-road vehicles fording water. Background Art

[0002] With the rise of off-road sports, off-road enthusiasts have put forward higher requirements for the wading ability of off-road vehicles in pursuit of excellent off-road performance, and the wading hose came into being. The main function of the wading hose is to move the air intake of the air filter intake pipe from inside and outside the engine compartment to the intersection of the A-pillar and the roof of the car, so that air can be directly taken from the atmospheric environment. After installing the wading hose, the wading depth of the off-road vehicle is greatly increased, from 450mm to 1600mm, or even deeper, which can effectively prevent the problem of engine water ingress and flameout when the vehicle is wading.

[0003] Since the wading hose is installed on the fender and A-pillar sheet metal of the vehicle body, and the air filter is installed in the engine compartment, a connecting pipe is required between the two, namely the air filter intake pipe, which is used to transport the air sucked in by the wading hose to the air filter. Under normal road conditions, the air filter intake pipe of the car does not need to be completely sealed, but for off-road vehicles that wade in water, the air filter intake pipe between the wading hose and the air filter must be completely sealed, and no leakage points are allowed. Otherwise, when the vehicle is wading, water will be sucked in from the leak under the action of the engine suction negative pressure and eventually enter the engine, causing the engine to stall and the turbocharger to be damaged. At the same time, since the off-road vehicle with a wading hose is equipped, its air filter intake pipe needs to be installed between the frame and the wheel arch, the operating space is small, and the parts are blocked from each other. The operator cannot fully see it, so it needs to be installed blindly, which makes assembly very difficult. The traditional air filter intake pipe is installed in the engine compartment, so the operating space is large, the assembly is easy, and it does not need to be completely sealed. This is completely different from the application scenario of off-road wading vehicles. Ordinary air filter intake pipes can no longer meet the application scenarios of off-road wading vehicles. Therefore, the applicant proposes an air filter intake pipe for off-road wading vehicles to meet the requirements of sealing and assembly. Utility Model Content

[0035] The utility model embodiment provides an air filter intake pipe for off-road vehicle wading, referring to Figures 1 to 5 , comprising a blow molding tube 1, a bellows 2, a sealing ring 3, a bracket 4 and a sealing rib 5, wherein the bellows 2 is connected to the blow molding tube 1, the sealing ring 3 is installed on an interface at one end of the blow molding tube 1 away from the bellows 2, the bracket 4 is installed on a side of the blow molding tube 1 close to the sealing ring 3, and the sealing rib 5 is installed inside an interface at one end of the bellows 2 away from the blow molding tube 1;

[0036] Among them, one end interface of the air filter intake pipe 17 is connected to the wading hose 18 through a sealing ring 3, and the other end interface of the air filter intake pipe 17 is connected to the air filter inlet 19 through a sealing rib 5.

[0037] Specifically, the blow tube 1 is blow-molded by PP (polypropylene) modified material; the corrugated tube 2 is injection-molded by TPV (thermoplastic vulcanized rubber), and specifically applies a TPV corrugated hose molding device and production method (authorization announcement number CN115195037B) in the TPV corrugated hose; the sealing ring 3 and the sealing rib 5 are both molded by EPDM (ethylene propylene diene monomer rubber) material; the bracket 4 is injection-molded by PP modified material; the sealing ring 3 and the sealing rib 5 are both arranged in an annular shape; in this embodiment, there are 2 sealing ribs 5 with a diameter of 0.5 mm, which can be designed according to actual conditions, and the sealing ribs 5 are used to improve the sealing performance of the air filter intake pipe 17 and the air filter air inlet 19; the air filter intake pipe 17 and the wading hose 18 are plug-in assembled; the air filter intake pipe 17 and the air filter air inlet 19 are clamped assembled;

[0038] The air filter intake pipe 17 and the wading hose 18 are effectively sealed by the sealing ring 3 ; the air filter intake pipe 17 and the air filter inlet port 19 are effectively sealed by the sealing rib 5 .

[0039] For an off-road vehicle equipped with a snorkel 18, the air filter intake pipe 17 is difficult to assemble due to the small assembly space. In order to reduce the assembly difficulty, a bellows 2 is designed to absorb the cumulative assembly tolerance, adjust the assembly, and reduce the assembly difficulty. At the same time, since the air filter intake pipe 17 and the snorkel 18 are plug-in assembled, the axial freedom of installation is not completely restricted. There is a risk of the air filter intake pipe 17 escaping from the snorkel 18 during driving. Therefore, a bracket 4 is designed on the side of the blow molded tube 1 close to the sealing ring 3 to fix the air filter intake pipe 17 and prevent the air filter intake pipe 17 from escaping from the snorkel 18.

[0040] Among them, refer to Figure 1 and Figure 3 In this embodiment, a plurality of annular sealing teeth 6 are provided on the outer side of the sealing ring 3 .

[0041] Specifically, the sealing ring 3, the sealing teeth 6 and the sealing ribs 5 are all made of soft materials; in the present embodiment, the number of the sealing teeth 6 is 3, which can be designed according to actual conditions, and the sealing teeth 6 are arranged at an angle, specifically, they are arranged at an angle along the direction in which the sealing ring 3 is assembled and inserted into the blow molding tube 1. Through this design structure, the insertion force of the wading hose 18 and the air filter intake pipe 17 can be reduced, and the air tightness of the wading hose 18 and the air filter intake pipe 17 after assembly can be ensured.

[0042] The water wading hose 18 compresses the sealing teeth 6 on the sealing ring 3, thereby achieving effective sealing between the air filter intake pipe 17 and the water wading hose 18.

[0043] Reference Figure 2 In this embodiment, a clamp 7 is provided on the interface of one end of the corrugated tube 2 away from the blow molding tube 1.

[0044] Specifically, the clamp 7 is made of stainless steel and is formed by stamping; the interface of the air filter intake pipe 17 is connected to the air filter air inlet 19 through the sealing rib 5, and then the interface is clamped by the clamp 7, so that the sealing rib 5 can better contact with the air filter air inlet 19, thereby achieving effective sealing between the air filter intake pipe 17 and the air filter air inlet 19.

[0045] Reference Figure 3 In this embodiment, a plurality of blocks 8 are evenly arranged on the inner circumference of the sealing ring 3 , and a plurality of slots 9 for engaging with the blocks 8 are provided on the interface at one end of the blow molding tube 1 away from the corrugated tube 2 .

[0046] Specifically, the slots 9 are evenly distributed circumferentially on the interface of the end of the blow molding tube 1 away from the corrugated tube 2; in the present embodiment, the number of the blocks 8 and the slots 9 are both 4, which can be designed according to actual conditions; and the shapes of the blocks 8 and the slots 9 match, preferably, the blocks 8 and the slots 9 are T-shaped, and with this inverted assembly structure, the axial pull-off reliability of the sealing ring 3 after assembly is very high, and it can be firmly hung on the blow molding tube 1, ensuring that the sealing ring 3 will not be twisted and deformed during the insertion of the air filter intake pipe 17 into the snorkel 18, and the sealing ring 3 will not fall into the snorkel 18 due to movement during driving, causing abnormal noise in the product.

[0047] Reference Figure 4 In the present embodiment, a rubber-coated boss 10 is provided at one end of the bracket 4 close to the blow molding tube 1 , a rubber-coated flange 11 is provided on the edge of the rubber-coated boss 10 , and a plurality of countersunk holes 12 are opened on the rubber-coated boss 10 .

[0048] Specifically, the bracket 4 and the rubber-coated boss 10 are of an integrated design; a circle of rubber-coated flange 11 is provided on the edge of the rubber-coated boss 10; a groove for placing the rubber-coated boss 10 and the rubber-coated flange 11 is formed on the mold for manufacturing the blow molded tube 1; the mold for manufacturing the blow molded tube 1 has a countersunk hole groove corresponding to the countersunk hole 12, so that the blow molded tube 1 can be better combined with the rubber-coated boss 10, thereby achieving the purpose of increasing the rubber removal force of the bracket 4; the number of countersunk holes 12 is 2, and the diameter of the countersunk holes 12 is 10 mm, which can be designed according to actual conditions; the design structure of the rubber-coated flange 11 is 2 mm wide and 1.5 mm high.

[0049] In this embodiment, the connection between the blow molded tube 1 and the bracket 4 is achieved by blow molding. This structural design omits the welding process of the bracket 4 and reduces the manufacturing cost. In order to achieve the rubber coating of the bracket 4, when the blow molded tube 1 is blow-molded, the blow molding material can be tightly wrapped on the surface of the rubber coating flange 11, so that the two are combined with each other to form an integral part. In order to further enhance the pull-off force of the bracket 4 after rubber coating, a countersunk hole 12 is provided. During blow molding, the blow molding material enters and fills the space of the countersunk hole 12, thereby forming a rivet structure, thereby increasing the pull-off force of the rubber coating of the bracket 4.

[0050] Reference Figure 5 In this embodiment, the bellows 2 is provided with a plurality of corrugations 13 for vibration decoupling and adjustment of assembly tolerance.

[0051] Specifically, the number of the corrugations 13 is 4, which can be designed according to actual conditions.

[0053] Specifically, the bellows 2 and the blow molded tube 1 are welded together by hot plates. The advantage of this structural design is that the product has high integration and does not require excessive assembly steps. Compared with the traditional pipeline assembly sealing structure design, it saves the cost of clamps, steel rings and assembly clamps. In this embodiment, the welding interference between the blow molded tube welding boss 14 and the bellows welding boss 15 is 1.5 mm.

[0054] Reference Figure 5 In this embodiment, a material blocking rib 16 is provided on the bellows welding boss 15 to block the overflow during welding, so that there is no excessive overflow on the appearance of the parts after welding, thereby ensuring the aesthetic quality of the product's welding.
