[0024] like Figures 1 to 4 As shown, an automobile air intake hose assembly in one embodiment of the utility model includes a hose body 1.

[0025] like Figure 1 As shown, the outer side of the hose body 1 is integrally formed with multiple groups of reinforcing ribs 10. The multiple groups of reinforcing ribs 10 improve the use strength of the hose body 1.

[0026] like Figure 1As shown, a connecting pipe 8 is fixedly connected to one side of the hose body 1 close to the intake pipe 3. The connecting pipe 8 serves as an assembly limit and connection for the crankcase ventilation pipe 9. The crankcase ventilation pipe 9 is fixedly sleeved on the outer side of the connecting pipe 8. The crankcase ventilation pipe 9 is used to conduct gas between the hose body 1 and the crankcase.

[0027] like Figure 1 As shown, one end of the hose body 1 is fixedly connected to the air outlet pipe 2, and the end of the hose body 1 away from the air outlet pipe 2 is fixedly connected to the air inlet pipe 3.

[0028] like Figure 1 to Figure 2 As shown, the outer sides of the air outlet pipe 2 and the air inlet pipe 3 are both sleeved with a fixing clamp 4. The air outlet pipe 2 and the air inlet pipe 3 are sleeved and fixed by the fixing clamp 4.

[0029] like Figure 3 to Figure 4 As shown, the inner walls of the air outlet pipe 2 and the air inlet pipe 3 are fixedly connected with a heat insulating seal 5. The heat insulating seal 5 is used to assemble and limit a pair of auxiliary seals 6 and an extrusion seal 7. At the same time, the heat insulating seal 5 can play a role of heat insulating and limiting the air outlet pipe 2 and the air inlet pipe 3.

[0030] like Figure 3 to Figure 4 As shown, a pair of auxiliary sealing rings 6 are snap-fitted on the inner wall of the heat-insulating sealing pad 5, and an extrusion sealing ring 7 is arranged between the pair of auxiliary sealing rings 6. The extrusion sealing ring 7 is snap-fitted on the inner wall of the heat-insulating sealing pad 5. The pair of auxiliary sealing rings 6 and the extrusion sealing ring 7 are provided to improve the sealing and stability of the assembly of the outlet pipe 2 and the inlet pipe 3.

[0031] like Figure 3 to Figure 4 As shown, a pair of limiting bosses 11 are integrally formed on the outer sides of the air outlet pipe 2 and the air inlet pipe 3, and the pair of limiting bosses 11 are symmetrically distributed on both sides of the fixing clamp 4. The pair of limiting bosses 11 play the role of assembly limiting for the fixing clamp 4, reducing the situation of slipping of the fixing clamp 4 during the assembly and connection process.

[0032] like Figure 1 to Figure 2 As shown, both ends of the fixing clamp 4 are integrally formed with fixing bosses 12. The fixing clamp 4 is controlled to shrink by assembling and fixing the fixing bosses 12, so that the fixing clamp 4 is convenient to assemble and fix the air outlet pipe 2 and the air inlet pipe 3.

By drilling the weight-reducing through holes, the deadweight of the fixing clamp 4 is reduced, and the adverse effects of vibration on the hose body 1 are reduced.

[0035] Among them, a plurality of assembly slots are cut on the inner wall of the heat insulation seal 5, and the plurality of assembly slots are respectively matched with a pair of auxiliary sealing rings 6 and an extrusion sealing ring 7. The auxiliary sealing ring 6 and the extrusion sealing ring 7 are assembled and limited by cutting the assembly slots, thereby improving the use stability of the auxiliary sealing ring 6 and the extrusion sealing ring 7.

[0036] Preferably, the diameter of the extrusion sealing ring 7 is larger than the diameter of the auxiliary sealing ring 6, and a pair of extrusion shrinkage grooves are formed between the extrusion sealing ring 7 and the pair of auxiliary sealing rings 6. The pair of extrusion shrinkage grooves provide compression space for the auxiliary sealing ring 6 and the extrusion sealing ring 7.

[0037] During specific use, when the hose body 1 is assembled and fixed, the connecting pipe is flexibly supported and sealed by the cooperation of the heat insulating sealing pad 5, the auxiliary sealing ring 6 and the extrusion sealing ring 7. Subsequently, a pair of fixed bosses 12 are connected by controlling the rotation of the connecting threaded rod 13, so that the outlet pipe 2 and the intake pipe 3 are fixedly assembled on the outside of the connecting pipe through the fixed clamp 4. In the process of fixing the fixed clamp 4, the connecting pipe and the auxiliary sealing ring 6 and the extrusion sealing ring 7 can be squeezed against each other so that the auxiliary sealing ring 6 and the extrusion sealing ring 7 can perform auxiliary sealing and flexibly limit the connecting pipe, thereby improving the assembly sealing and stability of the automobile intake hose.
