[0002] With the gradual popularization of automobiles, the number of cars in the world has increased year by year, and the internal combustion engine is still the main power source of automobiles. The throttle of the car is the main component that controls the power output of the engine. When the engine is idling or under low load conditions, the throttle raft opening angle is very small, and a large vacuum will be formed behind the throttle.

[0003] In the related art, the intake end of the throttle is connected to an intake duct. In order to reduce the noise generated by the resonance between the intake duct and the throttle, it is usually necessary to design it as a soft structure. However, the strength of the intake duct with the above soft structure is relatively low and cannot meet the high negative pressure resistance requirements of the throttle assembly.

In this way, the strength and rigidity of the air intake hose can be improved to meet the negative pressure resistance requirements of the air intake hose and avoid the air intake hose from being greatly deformed under high negative pressure conditions. Therefore, the air intake hose of the utility model can not only meet the use requirements of negative pressure resistance, but also reduce noise, and has a good use effect.

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0033] Please refer to the following Figures 1 to 5 An air intake hose, a throttle valve assembly and a vehicle according to embodiments of the utility model are described.

[0034] like Figures 1 to 5As shown, according to the intake hose 1 of the embodiment of the utility model, the intake hose 1 is used to be connected to the throttle valve 2. The intake hose 1 includes a hose body 11 and a support layer. The support layer is arranged in the tube wall of the hose body 11. The support layer has multiple circles, and the multiple circles of the support layer are arranged in a radially stacked manner along the hose body 11.

[0035] According to the air intake hose 1 of the utility model, since the air intake hose 1 is a hose structure, the noise caused by the resonance of the throttle valve 2 can be reduced. Since the support layer is arranged in the tube wall of the hose body 11, the support layer has multiple circles, and the multiple circles of the support layer are stacked and arranged along the radial direction of the hose body 11. In this way, the strength and rigidity of the air intake hose 1 can be improved to meet the negative pressure resistance requirements of the air intake hose 1 and avoid the air intake hose 1 from being greatly deformed under high negative pressure. Therefore, the air intake hose 1 of the utility model can not only meet the use requirements of negative pressure resistance, but also reduce noise, and has a good use effect.

[0036] In the example of the present application, the air intake hose 1 can be elastically deformed. When the air intake hose 1 is assembled, one end of the air intake hose 1 is connected to the throttle valve 2 , and the other end of the air intake hose 1 is communicated with the intake manifold 3 .

[0037] It is understandable that the throttle valve 2 of the intake hose of the utility model is connected to the intake manifold 3 through the intake hose 1, which can prevent the weight of the throttle valve 2 from acting entirely on the intake manifold 3, so as to achieve a decoupling design between the throttle valve 2 and the intake manifold 3, and improve the system modal and NVH performance of the intake manifold 3. Among them, the support layer can strengthen the tube wall of the hose body 11, thereby greatly reducing the probability of the intake hose 1 being sucked and deflated when the throttle valve 2 is working, so as to meet the high negative pressure resistance requirement of the intake hose 1.

[0038] Optionally, at least one circle of supporting layer includes a reinforcing layer 12 and an elastic layer 111, and the reinforcing layer 12 is buried in the elastic layer 111. In the example of the present application, each circle of supporting layer includes a double-layer structure of the reinforcing layer 12 and the elastic layer 111. Figure 4 The dotted line in the figure represents the reinforcing layer 12, and the part outside the dotted line is the elastic layer 111. The reinforcing layer 12 is arranged inside the elastic layer 111. Figure 5 The figure shows the cross-sectional structure of the single-circle elastic layer 111 and the reinforcement layer 12 .

[0039] For example, multiple circles of elastic layers 111 are bonded and fixed to form the hose body 11, and a circle of reinforcing layer 12 is arranged inside each circle of elastic layer 111. In other words, a sandwich cavity is arranged inside each circle of elastic layer 111, and the reinforcing layer 12 is arranged inside the sandwich cavity. This can reduce the probability of resonance among the throttle valve 2, the intake hose 1 and the intake manifold 3, and avoid the problem of resonance failure of the throttle valve assembly and noise generated by resonance.

[0040] For example, multiple circles of elastic layers 111 can be spirally wound to form the hose body 11. For another example, multiple circles of elastic layers 111 can also be coaxially nested with each other to form the hose body 11. The present application does not specifically limit the molding method of the hose body 11.

[0041] Optionally, the elastic layer 111 is one of a silicone layer, a fluororubber layer, an acrylate rubber layer, and an ethylene acrylate rubber layer, and the reinforcing layer 12 is one of an aramid layer, a polyester layer, and a nylon layer. The inventors of the present application have found through experimental research that when the elastic layer 111 and the reinforcing layer 12 are made of the above materials, it is beneficial to improve the overall negative pressure resistance performance of the intake hose 1 and facilitate assembly.

[0042] In the example of the present application, the elastic layer 111 is a silicone layer, and the reinforcing layer 12 is an aramid layer. In other words, the elastic layer 111 is made of silicone material, adjacent silicones are connected by bonding, and the reinforcing layer 12 is made of aramid material.

[0043] In some embodiments, Figure 5 As shown, the thickness of each circle of the elastic layer 111 is A, and the number of circles of the elastic layer 111 is B, wherein 0.8 mm ≤ A ≤ 1.2 mm, and 5 ≤ B ≤ 7. It can be understood that the thickness of each circle of the elastic layer 111 is between 0.8 mm and 1.2 mm, the number of circles of the elastic layer 111 is 5-7, and a circle of the reinforcing layer 12 is disposed in each circle of the elastic layer 111. For example, A can be 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, and 1.2 mm.

[0044] The inventors of the present application have discovered through experimental research that if the thickness of the single-circle elastic layer 111 is less than 0.8 mm, the overall rigidity of the air intake hose 1 will be insufficient, thereby resulting in insufficient negative pressure resistance of the air intake hose 1; and if the thickness of the single-circle elastic layer 111 is greater than 1.2 mm, the air intake hose 1 will be too hard, thereby affecting assembly.

[0045] For example, the hardness of the tube body after vulcanization is required to be 70HA-90HA (Shore hardness). The negative pressure resistance value of the hose that meets the above requirements can reach above -90kPa (at 100°C). This intake hose 1 can meet the high negative pressure resistance requirements behind the throttle valve 2 while ensuring the assemblability of the hose.

[0046] Alternatively, if Figure 2As shown, the outer diameter of the air intake hose 1 is D, 10mm≤D≤70mm. The inventor of the present application found through experimental research that when the outer diameter of the air intake hose 1 is greater than 70mm, the probability of the air intake hose 1 being sucked and deflated is high when the throttle valve 2 is working, that is, the negative pressure resistance performance of the air intake hose 1 is poor. When the outer diameter of the air intake hose 1 is less than 70mm, the vibration reduction effect of the air intake hose 1 is poor, and the throttle valve 2 and the intake manifold 3 are prone to resonance, and the noise is relatively large. Therefore, setting the outer diameter of the air intake hose 1 in the range of 10mm-70mm can not only reduce the probability of the air intake hose 1 being sucked and deflated when the throttle valve 2 is working, so as to meet the high negative pressure resistance requirements of the air intake hose 1; but also reduce the probability of resonance among the throttle valve 2, the air intake hose 1 and the intake manifold 3, and avoid the problem of resonance failure of the throttle valve assembly and noise generated by resonance.

[0047] In one example, if Figure 2 As shown, the air intake hose 1 is a curved tube, and the extension length of the air intake hose 1 is L1, L1≤120mm. For example, the air intake hose 1 is a right-angled hose, that is, the axis of the air intake port of the air intake hose 1 is perpendicular to the axis of the air outlet port of the air intake hose 1. The inventor of the present application found through experimental research that when the air intake hose 1 is a curved tube, if the extension length L1 of the air intake hose 1 is greater than 120mm, the negative pressure resistance of the air intake hose 1 is likely to be reduced. Therefore, the air intake hose of the embodiment of the utility model can ensure the negative pressure resistance of the air intake hose 1 by setting the extension length L1 of the curved air intake hose 1≤120mm, which is beneficial to improving the reliability of the operation of the air intake hose 1.

[0048] In another example, if Figure 3 As shown, the air intake hose 1 is a straight tube, and the extension length of the air intake hose 1 is L2, L1≤100mm. For example, the air intake hose 1 is straight, that is, the axis of the air intake port of the air intake hose 1 is collinear with the axis of the air outlet port of the air intake hose 1. The inventor of the present application found through experimental research that when the air intake hose 1 is a straight tube, if the extension length L2 of the air intake hose 1 is greater than 100mm, the negative pressure resistance of the air intake hose 1 is likely to be reduced. Therefore, the air intake hose of the embodiment of the utility model can ensure the negative pressure resistance of the air intake hose 1 by setting the extension length L2 of the straight air intake hose 1 ≤100mm, which is beneficial to improving the reliability of the operation of the air intake hose 1.

[0049] A throttle assembly of another embodiment of the utility model comprises an intake hose 1, a throttle 2 and an intake manifold 3. The intake hose 1 is the intake hose 1 in the embodiment of the utility model, one end of the intake hose 1 is connected to the throttle 2, and the other end of the intake hose 1 is connected to the intake manifold 3.

[0050] According to the throttle valve 2 assembly of the embodiment of the utility model, the throttle valve 2 can be connected to the intake manifold 3 through the intake hose 1. Since the intake hose 1 is a hose structure, the noise caused by the resonance between the throttle valve 2 and the intake manifold 3 can be reduced. Since the support layer is arranged in the tube wall of the hose body 11, the support layer has multiple circles, and the multiple circles of support layers are stacked and arranged along the radial direction of the hose body 11. In this way, the strength and rigidity of the intake hose 1 can be improved to meet the negative pressure resistance requirements of the intake hose 1 and avoid the intake hose 1 from being greatly deformed under high negative pressure. Therefore, the intake hose 1 of the utility model can not only meet the use requirements of negative pressure resistance, but also reduce noise, and has a good use effect.

[0051] It is understandable that the throttle valve 2 of the intake hose 1 of the utility model is connected to the intake manifold 3 through the intake hose 1, which can prevent the weight of the throttle valve 2 from acting entirely on the intake manifold 3, so as to achieve a decoupling design between the throttle valve 2 and the intake manifold 3, and improve the system modal and NVH performance of the intake manifold 3. Among them, the support layer can strengthen the tube wall of the hose body 11, thereby greatly reducing the probability of the intake hose 1 being sucked and deflated when the throttle valve 2 is working, so as to meet the high negative pressure resistance requirement of the intake hose 1.

[0052] Alternatively, if Figure 1 As shown, the throttle valve 2 assembly further includes a clamp 4, and at least one of the throttle valve 2 and the intake manifold 3 is connected to the intake hose 1 through the clamp 4. For example, the connection position between the throttle valve 2 and the intake hose 1 and the connection position between the intake manifold 3 and the intake hose 1 are both provided with a clamp 4, thereby facilitating the disassembly and assembly of the intake hose 1, and the installation is highly secure.

[0053] A vehicle of another embodiment of the utility model comprises a throttle valve 2 assembly and an engine, wherein the throttle valve 2 assembly is the throttle valve 2 assembly of the embodiment of the utility model, and the intake manifold 3 is connected to the engine. For example, the vehicle further comprises a manifold bracket 5, which is connected to the intake manifold 3 and the engine, thereby improving the stability of the connection between the intake hose 1 and the engine.
