[0033] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. Additionally, it should be noted that for the sake of description, only the parts related to the invention are shown in the drawings.

[0034] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and embodiments.

[0035] For the sake of clear and concise description of the following embodiments, a brief introduction to the related art is given first:

[0036] In the prior art, as Figure 12 , Figure 13 and Figure 14 shown, the interior of an automotive seat at least includes: a back spring 6 and a gas source 3. A back plate 7 is provided on the back spring 6, and a controller 9 and a gas-using component 8 are provided on the back plate 7. The controller 9 has an air inlet end and an air outlet end. The air inlet end is connected to the gas source 3 through an existing tracheal structure a, and the air outlet end and the gas-using component 8 are connected through the existing tracheal structure a; the controller 9 is used to control the intake and exhaust of the gas-using component 8; however, the position where the existing tracheal structure is connected to the gas source 3 has a large-angle bending problem inside the automotive seat. Since there is no support structure between the existing tracheal structure itself and its pipe wall, the bent position is prone to being folded to death, or the flow rate is reduced after bending, resulting in abnormal phenomena such as abnormal sounds. Therefore, the present application designs an anti-bending connecting trachea to solve the above problems.

[0037] In order to make the anti-bending connecting trachea provided by the embodiments of the present application clearer and easier to understand, the trachea will be introduced below with reference to the accompanying drawings. As Figure 1 shown, this figure is a schematic diagram of the overall structure of the anti-bending connecting trachea provided by the embodiments of the present application. The trachea includes:

[0038] A tracheal body 1, and the tracheal body 1 is arranged inside the automotive seat; the inside of the tracheal body 1 is hollow to form a channel for gas to flow through; as Figure 2 and Figure 3 shown, a plurality of tooth-shaped structures 2 are provided on the inner wall of the tracheal body 1. All the tooth-shaped structures 2 are circumferentially distributed along the inner wall of the tracheal body 1. The extending direction of each tooth-shaped structure 2 is the same as the extending direction of the tracheal body 1, and a deformable space is formed between the tooth-shaped structures 2.

[0039] It should be noted that the inside of the tracheal body 1 is hollow to form a channel for allowing gas to flow through. Here, the material of the tracheal body 1 is, for example, polyester, polyurethane, polyether, PVC, rubber and plastic, polyethylene or silicone, so that the tracheal body 1 has a certain flexible bending ability.

[0040] The dentate structure 2 is arranged on the inner wall of the trachea body 1, and the number thereof is multiple. All the dentate structures 2 are circumferentially distributed along the inner wall of the trachea body 1. The deformable space of the dentate structure 2 is communicated with the channel. When the anti-bending connection trachea is in a bent state, the trachea body 1 deforms, and the dentate structure 2 also deforms accordingly. The deformable space will deform, that is, the dentate structure 2 itself generates a deformation force and the adjacent dentate structures 2 also exert pressure on each other to generate a force, so as to resist the deformation force when the trachea body 1 is bent, so that there is a gap inside the trachea body 1, and it is avoided that the inner space of the trachea body 1 is completely blocked due to bending, resulting in a sharp drop in gas flow rate, generating a large noise, and affecting the driving experience of the vehicle. In addition, even if the bending angle is extremely small, due to the existence of the deformable space, the air flow can continue to flow through the deformable space, and there will be no completely blocked phenomenon. The dentate structure 2 also has the effects of stabilizing the air flow and reducing noise. Generally, the gas output from the gas source is a spiral air flow, which is prone to generate noise when flowing in the trachea. The dentate structure 2 also has an air flow guiding function, which can make the air flow stable and reduce the noise generated when the air flow flows, so as to achieve the effect of noise reduction.

[0041] Further, as Figure 4 , Figure 5 shown, a plurality of dentate structures 2 are also arranged on the outer wall of the trachea body 1, and all the dentate structures 2 located on the outer wall are circumferentially distributed along the outer wall of the trachea body 1. When the anti-bending connection trachea is in a bent state, the trachea body 1 deforms, and the dentate structures 12 on the inner wall and the outer wall of the trachea body 1 also deform, so that the corresponding deformable space deforms, and the adjacent dentate structures 2 press against each other to generate a force, improving the ability to resist the deformation force when the trachea body 1 is bent, and ensuring that the trachea body 1 will not be completely blocked due to bending.

[0042] Further, the dentate structures 2 are uniformly distributed or non-uniformly distributed.

[0043] Specifically, when the dentate structures 2 are uniformly distributed, that is, the whole trachea body 1 has the same anti-deformation ability at each position, no matter which direction or angle the trachea body 1 is bent, it can be ensured that there is a gap inside the trachea body 1, and it is avoided that the inner space of the trachea body 1 is completely blocked due to bending.

[0044] When the dentate structures 2 are non-uniformly distributed, that is, according to the actual application environment of the anti-bending connection trachea, the bending habit is obtained. According to the bending habit, a larger number or densely arranged dentate structures 2 are designed on both sides of the bending position, and a smaller number of dentate structures 2 are designed at the position that is not easily bent or the position with less force, which not only ensures that there is a gap inside the trachea body 1, but also improves the stability of the gap of the trachea body 1, effectively avoiding the phenomenon that the inner space of the trachea body 1 is completely blocked due to bending.

[0045] Based on the above, whether it is a uniform distribution or a non-uniform distribution, the tooth-shaped structure 2 can be designed to be densely distributed or non-densely distributed, which can enhance the mutual extrusion force between the tooth-shaped structures 2, improve the anti-deformation ability of the trachea body 1, effectively prevent the internal space of the trachea body 1 from being blocked, avoid a rapid decrease in gas flow, reduce noise, and enhance the driving experience of the vehicle.

[0046] In addition, the height of the tooth-shaped structure 2 is 0.8 times to 2.2 times the wall thickness of the trachea body 1. This enables the deformable space to have the ability to deform while ensuring that there are gaps in the channel for gas to flow through.

[0047] Furthermore, the cross-section of the tooth-shaped structure 2 is a regular shape or an irregular shape. Here, the regular shape is, for example, a conical shape or a trapezoidal shape; the irregular shape can be designed with different specifications of the tooth-shaped structure 2 according to the bending habit.

[0048] In addition, as Figure 2 shown, one end of the tooth-shaped structure 2 away from the inner wall of the trachea body 1 can be a broken line shape, and one end of the tooth-shaped structure 2 away from the inner wall of the trachea body 1 can also be an arc shape.

[0049] Furthermore, the trachea body 1 and the tooth-shaped structure 2 are an integrally formed structure, making the trachea body 1 more firm and durable, and ensuring the stability and service life of the trachea.

[0050] Among them, the material of the tooth-shaped structure 2 is polyester, polyurethane, polyether, PVC, rubber and plastic, polyethylene or silicone. It has excellent elastic recovery ability and can withstand frequent bending and stretching, further ensuring the service life and stability of the trachea.

[0051] As Figure 6 、 Figure 7 and Figure 8 shown, the present application also provides an automotive seat pneumatic system, including: a gas source 3, a mounting shell sleeve 4 and the above-mentioned anti-bending connecting trachea; the mounting shell sleeve 4 is arranged inside the automotive seat, and the mounting shell sleeve 4 has a receiving space for placing the gas source 3; the gas source 3 is connected to a gas-using component 8 through the anti-bending connecting trachea.

[0052] It should be noted that the gas-using component 8 is, for example, an airbag; the gas source 3 is, for example, an air pump; one end of the anti-bending connecting trachea is connected to the gas-using component, and the other end is connected to the air inlet of the air pump. The automotive seat pneumatic system has the functions and advantages of the above-mentioned anti-bending connecting trachea, which will not be elaborated in detail here.

[0053] In addition, as Figure 12 、 Figure 13 and Figure 14As shown in the figure, the present application also provides an automotive seat pneumatic system, which includes: a gas-using component 8, a gas source 3, a controller 9, and the above-mentioned anti-bending connecting air pipe;

[0054] Inside the automotive seat, there is a back spring 6. A back plate 7 is arranged on the back spring 6. The gas-using component 8 and the controller 9 are arranged on the back plate 7. The controller 9 has an air inlet end and an air outlet end. The air inlet end is connected to the gas source 3 through the anti-bending connecting air pipe, and the air outlet end is connected to the gas-using component 8 through the anti-bending connecting air pipe. The controller 9 is used to control the air intake and exhaust of the gas-using component 8.

[0055] It should be noted that the gas-using component 8 is, for example, an airbag; this automotive seat pneumatic system has the functions and advantages of the above-mentioned anti-bending connecting air pipe, which will not be elaborated here in detail.

[0056] The present application also provides an automotive seat pneumatic system, which includes: a gas-using component 8, a gas source 3, a controller 9, a mounting shell sleeve 4, and the above-mentioned anti-bending connecting air pipe; the mounting shell sleeve 4 is arranged inside the automotive seat. The mounting shell sleeve 4 has an accommodating space for placing the gas source 3; the gas source 3 is an air pump, and the anti-bending connecting air pipe is communicated with the air inlet of the air pump.

[0057] The air inlet of the air pump intakes air through the anti-bending connecting air pipe, which can also reduce the noise generated when the air pump intakes air.

[0058] This automotive seat pneumatic system has the functions and advantages of the above-mentioned anti-bending connecting air pipe, which will not be elaborated here in detail.
