Description

Technical Field

[0001] The utility model relates to the technical field of air intake hoses, in particular to an improved air intake hose for an automobile power system. Background Art

[0002] The automobile intake hose, also known as the intake pipe, air pipe, air filter hose, etc., is a key component connecting the automobile air filter box and the throttle. Its main task is to transport air to the automobile engine, mix with fuel and burn, thereby driving the car.

[0003] like Figure 4 As shown, the structure of the intake hose for the previous generation of power system is similar to most of the intake hoses on the market and is made of rubber, silicone or plastic injection molding. This intake hose made of a single material has the following shortcomings during actual use: Since the intake end of the intake hose is connected to the air filter and the outlet end of the intake hose is connected to the engine throttle, the outlet end of the intake hose is often susceptible to the high temperature of the engine. During long-term use, the outlet end of the intake hose is prone to heat damage, aging and cracking, thereby reducing the service life and stability of the intake hose.

[0004] In view of this, it is particularly important to design and manufacture an intake hose with a stable structural load-bearing structure and the ability to reduce local heat accumulation and thermal loss and aging of the pipe body for use in automotive power systems. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the air outlet end of the traditional air intake hose for automobile power system is easily affected by the high temperature of the engine and causes heat damage, aging or cracking, resulting in a reduced service life of the air intake hose and poor stability in use, and to propose an improved air intake hose for automobile power system.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An improved air intake hose for an automobile power system comprises a plastic tube body, a corrugated expansion end integrally fixed to the plastic tube body on one side close to an air outlet end, an air intake clamp groove provided on the outside of the air intake end of the plastic tube body, an air outlet clamp groove provided on the outside of the air outlet end of the plastic tube body, a reinforcing rib integrally fixed between the air outlet end of the plastic tube body and the outside of the corrugated expansion end, and a flow meter mounting seat integrally fixed to the outside of the air outlet end of the plastic tube body, a hollow mesh layer for strengthening the plastic tube body against cracking being fixedly connected to the middle part of the plastic tube body, and a heat conducting part covering the hollow mesh layer and accelerating the heat dissipation treatment of the plastic tube body is provided on the inner side of the plastic tube body.

[0008] As a further description of the above technical solution:

[0009] The hollow mesh layer is formed by weaving together a plurality of groups of nylon threads distributed horizontally and vertically, and a through hole is formed in the middle of the nylon threads.

[0010] As a further description of the above technical solution:

[0011] The heat conducting part includes a heat absorbing layer fixed between the air outlet end and the corrugated expansion end of the plastic tube body, a heat dissipating layer fixed between the air inlet end and the corrugated expansion end of the plastic tube body, and a heat conducting layer filled inside the corrugated expansion end and located between the heat absorbing layer and the heat dissipating layer.

[0012] As a further description of the above technical solution:

[0013] The heat absorbing layer is made of copper foil material.

[0014] As a further description of the above technical solution:

[0015] The heat dissipation layer is made of aluminum foil material.

[0016] As a further description of the above technical solution:

[0017] The heat-conducting layer is made of heat-conducting silicone grease material.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0019] In the utility model, the original air intake hose structure is scientifically and rationally improved. Firstly, a hollow mesh layer is arranged in the middle of the plastic tube body, so that an anti-tear protection barrier can be formed inside the plastic tube body, thereby improving the anti-tear and anti-bending effects of the plastic tube body. At the same time, when a local impact acts on the plastic tube body, the hollow mesh layer can disperse the local impact force in the form of a surface, thereby avoiding the occurrence of the problem of impact damage to the plastic tube body. Secondly, a heat-conducting part that covers the hollow mesh layer and accelerates the heat dissipation of the plastic tube body is arranged on the inner side of the plastic tube body. The heat-conducting part is composed of a heat-absorbing layer made of copper foil material, a heat-dissipating layer made of aluminum foil material, and a heat-conducting layer made of thermally conductive silicone grease material. The plastic tube body has better thermal conductivity than that made of plastic materials. It can quickly absorb heat and conduct it to the outer layer of the plastic tube body and the aluminum foil. The thermal conductive silicone grease can quickly diffuse the heat absorbed by the copper foil and conduct it to the aluminum foil. Since the aluminum foil is at the air inlet end of the plastic hose, the aluminum foil can be continuously cooled when air enters, accelerating the dissipation of heat inside the plastic tube body. This structure can form a stable tear-resistant load-bearing structure inside the plastic tube body. At the same time, the heat absorbed locally at the air outlet end of the plastic tube body can be efficiently conducted and dissipated, reducing the occurrence of heat loss, aging and cracking problems of the air intake hose, thereby extending the service life of the air intake hose and improving the stability of the actual use of the air intake hose.

[0026] 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 of 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.

[0027] See also Figure 1-4 The utility model provides a technical solution: an improved air intake hose for an automobile power system, comprising a plastic tube body 1, a corrugated telescopic end 101 integrally fixed to the plastic tube body 1 near the air outlet end, an air intake clamp groove 102 provided on the outside of the air intake end of the plastic tube body 1, an air outlet clamp groove 103 provided on the outside of the air outlet end of the plastic tube body 1, a reinforcing rib 104 integrally fixed between the air outlet end of the plastic tube body 1 and the outside of the corrugated telescopic end 101, and a flow meter mounting seat 105 integrally fixed to the outside of the air outlet end of the plastic tube body 1, a hollow mesh layer 2 for anti-cracking reinforcement of the plastic tube body 1 is fixedly connected to the middle part of the plastic tube body 1, and a heat conducting part covering the hollow mesh layer 2 and accelerating the heat dissipation treatment of the plastic tube body 1 is arranged on the inner side of the plastic tube body 1.

[0028] Specifically, Figure 1-3As shown, the hollow mesh layer 2 is woven by combining multiple groups of nylon threads 201 distributed horizontally and vertically, which can form a stable tear-resistant protective barrier inside the plastic tube body 1. On the one hand, the local impact can be dispersed in the form of a surface, reducing the local impact damage and breakage of the plastic tube body 1. On the other hand, the internal structure of the plastic tube body 1 can be made tighter and more stable, reducing the occurrence of heat damage, aging and cracking of the plastic tube body 1. A through hole 202 is formed in the middle of the nylon thread 201. On the one hand, the material cost of the hollow mesh layer 2 can be reduced. On the other hand, the nylon thread 201 with the through hole 202 can form a hollow structure inside, which can make the hollow mesh layer 2 more elastic after manufacture. When the hollow mesh layer 2 is fused into the plastic tube body 1 by injection molding, it is not easy to affect the normal expansion and contraction adjustment and bending use of the plastic tube body 1.

[0029] Specifically, Figure 1-3 As shown, the heat conducting part includes a heat absorbing layer 3 fixed between the air outlet end of the plastic pipe body 1 and the corrugated expansion end 101, a heat dissipation layer 4 fixed between the air inlet end of the plastic pipe body 1 and the corrugated expansion end 101, and a heat conducting layer 5 filled inside the corrugated expansion end 101 and located between the heat absorbing layer 3 and the heat dissipation layer 4. The heat absorbing layer 3 is made of copper foil material, which can make the heat absorbing layer 3 have excellent thermal conductivity, can quickly absorb the heat at the air outlet end of the plastic pipe body 1, and conduct it to the outer layer of the plastic pipe body 1 and the heat dissipation layer 4. The heat dissipation layer 4 is made of aluminum foil material. Although its heat conductivity is The heat conduction effect is lower than that of the heat absorption layer 3 made of copper foil material, but its material cost is lower. Therefore, the heat absorption layer 3 and the heat dissipation layer 4 structure formed by the combination of copper foil and aluminum foil can rationally use the material combination according to the heat distribution of the plastic pipe body 1 when it is working. On the premise of improving the heat absorption, heat conduction and heat dissipation effects of the plastic pipe body 1, the manufacturing cost of the plastic pipe body 1 can be saved. The heat conduction layer 5 is made of thermally conductive silicone grease material, has excellent heat conduction effect, can quickly disperse and conduct the heat absorbed by the heat absorption layer 3 to the heat dissipation layer 4, and accelerate the dissipation of heat at the air outlet of the plastic pipe body 1.

[0030] Working principle: When making an air intake hose, first, combine and connect the heat absorption layer 3 made of copper foil material and the heat dissipation layer 4 made of aluminum foil material, and then fill the heat conductive layer 5 made of thermal conductive silicone grease material between the connecting ends of the heat absorption layer 3 and the heat dissipation layer 4; secondly, pre-set the hollow mesh layer 2 between the outside of the combined heat absorption layer 3 and the heat dissipation layer 4; finally, put the combined heat absorption layer 3, the heat dissipation layer 4 and the hollow mesh layer 2 into the injection mold of the air intake hose, and use rubber, silicone or plastic as the injection material to fill it into the injection mold, so that a plastic tube body 1 is formed between the heat absorption layer 3, the heat dissipation layer 4 and the outer layer of the hollow mesh layer 2; after the plastic tube body 1 is cooled and solidified, the manufactured air intake hose can be taken out of the injection mold.
