Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile parts, in particular to a composite air reservoir and a vehicle thereof. BACKGROUND

[0002] The existing air inlet drying equipment of a vehicle cannot completely remove moisture, so that water will accumulate inside the air reservoir after long-term operation, affecting the work efficiency of the parts and the safety of use in winter, and therefore, drainage needs to be performed regularly. Due to the reason of gravity flow, the existing metal air reservoir arranges a drainage valve at the bottom of the cylinder body.

[0003] Fiber winding is a widely used composite material reinforcement technology, the principle of which is to wind continuous fibers impregnated with resin matrix at a certain angle according to the product to be reinforced, so that the part covered by the wound layer can be reinforced after curing. It is widely used in aerospace fuel, high-pressure gas cylinders and other fields, and can greatly reduce the weight compared with metal pressure containers of the same performance, but it has strict requirements for the shape of the wound body. The wound body must be a completely axisymmetric barrel or rod, otherwise the wound fibers will form a "bridge" and cause local strength defects. Therefore, the existing fiber winding air reservoir cannot arrange a drainage hole at the bottom, but can arrange a drainage hole at the two side end covers to drain water laterally through "pressure difference". However, the end of the drainage pipe only contacts a small area in the inner container. Since the existing inner container material is mostly polyethylene or nylon, the material has a large hydrophilic contact angle, and the residual water in the cylinder will form water droplets or water clusters similar to the surface of a "lotus leaf" in the area away from the end of the drainage pipe, thereby causing incomplete drainage. In addition, the vehicle is parked at an angle, or the installation angle of the air reservoir is inclined, which may cause water to accumulate on one side of the cylinder. In addition, the existing air reservoir has poor rigidity of the lateral drainage pipe, which will shake during vehicle operation, and there is no effective means to ensure that the end of the drainage pipe is in close contact with the bottom of the inner container of the air reservoir. The end of the drainage pipe may be suspended, thereby affecting the drainage effect. SUMMARY

DETAILED DESCRIPTION

[0033] In order to make the personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0034] Referring to Figures 1 to 11 The embodiment of the present application provides a composite air cylinder and a vehicle thereof, which can solve the problem of incomplete drainage of water in the air cylinder and poor drainage effect in the related art.

[0035] In a first aspect, the embodiment of the present application provides a composite air cylinder, which comprises: an inner container 1, an insert 2, a drain joint 3 and a drain pipe 5, the insert 2 is arranged at the end of the inner container 1; the drain joint 3 is arranged on the insert 2; the drain pipe 5 comprises a second section 50 and a first section 52 connected to each other, the first section 52 penetrates the drain joint 3, the second section 50 is located in the inner container 1 and is attached to the inner wall of the inner container 1, and a plurality of drain holes 51 are distributed on the second section 50 along the length direction thereof.

[0036] In the present application, by setting the second section 50 and the first section 52 connected with each other, and making the second section 50 of the drain pipe 5 closely fit the inner container 1, and opening the drain hole 51 on the second section 50, it ensures that the water remaining inside the inner container 1 is drained out of the inner container 1 through the drain hole 51 on the second section 50 closely fitted with the inner container 1, maximizing the drainage efficiency.

[0037] It should be noted that in the present application, the inserts 2 are fixed at both ends of the inner container 1, and the drain connector 3 is installed on at least one of the inserts 2, and the air exhaust connector 4 is installed on both inserts 2, which is used for the installation of the air exhaust pipe.

[0038] At the same time, in some possible embodiments, the drain pipe 5 is connected with the drain connector 3 through the joint 9. In the present embodiment, the joint 9 includes a threaded structure 90 and a joint structure 91. The threaded structure 90 is threadedly connected with the drain connector 3, that is, a threaded groove is provided on the inner wall of the drain connector 3, so that the drain connector 3 is threadedly connected with the threaded structure 90 of the joint 9, to facilitate replacement of the joint 9 and the drain pipe 5, and the joint 9 can be detached by rotating when replaced; the joint structure 91 is clamped with the drain pipe 5. In the present embodiment, the first section 52 of the drain pipe 5 is connected with the joint 9 by interference clamping, so that the first section 52 of the drain pipe 5 is tightly connected with the joint 9. This connection not only ensures the stability between the drain pipe 5 and the joint 9, but also effectively prevents loosening or falling caused by water flow impact or external force, and enhances the sealing between the drain pipe 5 and the joint 9.

[0039] In other possible embodiments, the drain pipe 5 is connected with the drain connector 3 through the joint 9. In the present embodiment, the joint 9 is fixedly connected with the drain connector 3, and the drain pipe 5 is fixedly connected with the joint 9, which can greatly reduce the possibility of water penetration and avoid leakage caused by loose connection.

[0040] In the present application, the first section 52 of the drain pipe 5 is closely fitted with the inside of the inner container 1, avoiding the influence of the suspended end of the drain pipe 5 on the drainage effect. The shape of the drain pipe 5 has various setting modes:

[0041] In some possible embodiments, the second section 50 is a straight pipe extending axially along the inner container 1, as shown in Figure 3 Figure 3 The second section 50 and the inner wall of the inner container 1 are in line contact.

[0042] In the present embodiment, in order to better drain the second section 50, the second section 50 is closely fitted with the inner wall of the inner container 1. A water absorbing material 6 is installed on the second section 50, which can be a foam water absorbing material 6. See Figure 4 ​As shown, in order to ensure the stability of the connection between the water absorption material 6 and the second section 50, the water absorption material 6 and the second section 50 are fixed by adhesion; in some possible embodiments, if the water absorption material 6 is relatively hard, a clamping groove can be formed on the water absorption material 6, and the second section 50 is clamped in the clamping groove, and the place where the second section 50 is attached to the water absorption material 6 is fixed by adhesion; in some possible embodiments, if the water absorption material 6 is flexible and soft and can be freely rolled, only the place where the second section 50 is attached to the water absorption material 6 needs to be fixed by adhesion. The water drainage holes 51 are uniformly formed on the second section 50 along the length extension direction of the second section 50, and the water drainage holes 51 can be arranged at at least one of the top end, the bottom end and the side end of the second section 50, to facilitate water absorption from different positions. It should be noted that the water absorption material 6 needs to be in contact with the water drainage holes 51, so that the water absorbed by the water absorption material 6 can enter the second section 50 through the water drainage holes 51. In this embodiment, in order to install the drain pipe 5 in place, a mark 20 is arranged on the surface of the insert 2 where the drain pipe 5 is installed, the mark 20 points to the direction in which the second section 50 of the drain pipe 5 is tightly attached to the inner container 1, and in this embodiment, the mark 20 is a vertical mark 20 and has an arrow shape.

[0043] In this embodiment, the first section 52 and the second section 50 can also be arranged, specifically, the first section 52 includes a first pipe section and a second pipe section, a first included angle is formed between the first pipe section and the second pipe section, the second pipe section is connected to the second section 50, and a second included angle is formed between the second pipe section and the second section 50, so that the second section 50 extends into the inner container 1 and is attached to the bottom end of the inner wall of the inner container 1, the first included angle and the second included angle are both greater than 90°, or the first included angle and the second included angle are both less than 90°, and it is necessary to ensure that the first included angle is less than the second included angle. Referring to Figure 8In the embodiment, the first included angle ∠1 is set to 77°, the second included angle ∠2 is set to 78°, and a chamfer R1=25mm is arranged at the connection between the first pipe segment and the second pipe segment, and a chamfer R2=25mm is arranged at the connection between the second pipe segment and the second segment 50. Meanwhile, the lengths of the first segment 52 and the second segment 50 are set according to specific conditions. In the embodiment, the length of the first segment 52 can be set to X3=404mm, the height difference between the top end and the bottom end of the second segment 50 is X2=50mm, and the length of the straight pipe part of the second segment 50 is X1=50mm. In the embodiment, the reinforcing ribs 7 are arranged on the inner wall of the drain pipe 5 at intervals in the circumferential direction of the drain pipe 5 to ensure the rigidity of the drain pipe 5 and avoid shaking of the drain pipe 5 caused by vehicle operation. After the drainage holes 51 are arranged on the first segment 52, the water absorption material 6 can be selected not to be arranged on the first segment 52 in order to save manufacturing costs. It should be noted that the specific selection is determined according to actual conditions, and the present application does not make any limitation. In the embodiment, in order to ensure that the drain pipe 5 is installed in place, a mark 20 is arranged on the surface of the insert 2 on which the drain pipe 5 is installed, and the mark 20 points to the direction in which the second segment 50 of the drain pipe 5 is close to the inner container 1. In the embodiment, the mark 20 is a vertical mark 20 and has an arrow shape.

[0044] In the embodiment, the water absorption material 6 can also be in the form of a sheet and be a foam water absorption material 6. Referring to Figure 9 As shown, the water absorption material 6 is fixed to the second segment 50 by a plurality of clamps 8. The water absorption material 6 between adjacent two clamps 8 is unfolded along the circumferential direction of the inner container 1 away from the second segment 50 to increase the water absorption area. In order to avoid the clamps 8 blocking the drainage holes 51 on the second segment 50, a certain interval is arranged between the clamps 8 and the adjacent drainage holes 51. In the embodiment, the clamps 8 are arranged on both sides of each drainage hole 51, and the clamps 8 located on both sides of a drainage hole 51 maintain a spacing X4=10.25mm, which can make the drainage hole 51 closely fit the foam water absorption material 6, and the foam not held by the clamps 8 can freely expand to both sides to maximize the water absorption area. Meanwhile, referring to Figure 11 As shown, the first segment 52 includes a first pipe segment and a second pipe segment, and a first included angle is formed between the first pipe segment and the second pipe segment. The second pipe segment is connected to the second segment 50 and forms a second included angle with the second segment 50, so that the second segment 50 extends into the inner container 1 and is close to the bottom end of the inner wall of the inner container 1. The first included angle and the second included angle are both greater than 90°, or the first included angle and the second included angle are both less than 90°, and it is necessary to ensure that the first included angle is less than the second included angle. Referring to Figure 8As shown, in this embodiment, the third angle ∠3 is set to 93°, the fourth angle ∠4 is set to 94°, and the chamfer at the connection between the first pipe segment and the second pipe segment is set to R1 = 35 mm, and the chamfer at the connection between the second pipe segment and the second segment 50 is set to R2 = 35 mm. At the same time, the lengths of the first segment 52 and the second segment 50 are set according to specific circumstances. In this embodiment, the first segment 52 can be set to X5 = 400 mm, the height difference between the top end and the bottom end of the second segment 50 is X6 = 130.42 mm, and the straight pipe part of the second segment 50 is X7 = 50 mm. Through the angle difference between the third angle ∠3 and the fourth angle ∠4, when the drain pipe 5 is in a free state, the end of the second segment 50 closer to the first segment 52 is lower than the end farther away from the first segment 52, that is, as shown: Figure 11 As shown, the end of the drain pipe 5 is lower than the surface of the air reservoir liner 1 in the free state, so that during assembly, the drain pipe 5 is tightly fitted to the inner wall of the liner 1 through its own elasticity, maximizing the drainage efficiency. In this embodiment, in order to install the drain pipe 5 in place, a mark 20 is also provided on the surface of the insert 2 where the drain pipe 5 is installed, and the mark 20 points to the direction in which the second segment 50 of the drain pipe 5 is tightly fitted to the liner 1. In this embodiment, the mark 20 is a vertical mark 20 and is in the shape of an arrow.

[0045] In some possible embodiments, the second segment 50 adopts a spiral pipe that extends axially along the liner 1, and the outer diameter of the spiral pipe is the same as the inner wall diameter of the liner 1.

[0046] In this embodiment, the outer peripheral part of the spiral pipe is in close contact with the liner 1, and this design ensures that there is no gap between the two. The contact part of the spiral pipe and the liner 1 is provided with a drain hole 51, which is designed to effectively drain the water that may accumulate. Therefore, no matter which direction the liner 1 is tilted, the residual water inside the liner 1 can be smoothly drained through the drain holes 51 on the spiral pipe that is in close contact with the liner 1, avoiding potential damage to the liner 1 caused by the accumulated water.

[0047] Further, water-absorbing materials 6 are also installed around the drain holes 51 of the spiral pipe. These water-absorbing materials 6 are tightly fitted to the edges of the drain holes 51, thereby maximizing the water-absorbing area and further improving the drainage efficiency. Such a design not only ensures that the accumulated water is quickly absorbed and drained, but also helps to keep the liner 1 dry and prolong its service life.

[0048] In summary, compared with the existing composite air cylinder, the application solves the problem that the end of the drain pipe 5 in the cylinder cannot be located at the lowest position, and in the installation process of the air cylinder, by observing the vertical mark 20 on the insert 2, the air cylinder is rotated to ensure that the end of the drain pipe 5 in the inner container 1 is located at the lowest position, and the second section 50 in the inner container 1 can ensure that water can be absorbed everywhere in the inner container 1 through the design of the plurality of drain holes 51, avoiding the accumulation of water droplets on the "lotus leaf" surface. In addition, by additionally installing the foam water absorption material 6, the foam water absorption material 6 can be fixed on the drain pipe 5 by the installation of the clamp 8, so that part of the area can be stretched to both sides, further increasing the water absorption area.

[0049] Through the design of the plurality of drain holes 51 and the foam water absorption material 6, the air cylinder can be tilted at various angles (X or Y rotation) to ensure that water accumulates around the drain pipe 5 as much as possible, increasing the drainage effect. The inner wall of the drain pipe 5 is provided with a reinforcing rib 7 to ensure rigidity and avoid pipe body shaking caused by vehicle operation; at the same time, through the angle design, the elasticity of the drain pipe 5 itself is utilized to ensure that the pipe body tightly fits the inner container 1 of the air cylinder, maximizing the drainage efficiency.

[0050] In the second aspect, the embodiments of the application provide a vehicle comprising the composite air cylinder provided by any of the above-mentioned embodiments of the application.

[0051] In the application, the second section 50 and the first section 52 are connected to each other, the second section 50 of the drain pipe 5 tightly fits the inner container 1, and the drain hole 51 is formed on the second section 50, so that the residual water in the inner container 1 is drained out of the inner container 1 through the drain hole 51 on the second section 50 which tightly fits the inner container 1, maximizing the drainage efficiency.
