Technical Field

[0001] This application relates to the field of vehicle gas storage technology, specifically to a vehicle gas storage tank assembly and a vehicle. Background Technology

[0003] Generally, different devices require different gas supply pressures. When the pressure requirements differ, different gas chambers are needed to store gases at different pressures. In related technologies, different gas storage cylinders are used to store gases at different pressures, but this leads to complex gas storage structure layouts, complex piping, and a large amount of temporary space required.

[0030] The first aspect of this application provides a gas tank assembly 100 for a vehicle. Figure 1 This is a schematic diagram of one embodiment of the vehicle air tank assembly 100 provided in this application. Figure 2 yes Figure 1 A schematic diagram of the gas tank assembly 100 of the vehicle shown from another perspective. Figure 3 yes Figure 2 The structure shown is a cross-sectional view along section line AA. Figure 4 yes Figure 2 The structure shown is a cross-sectional view along section line BB.

[0031] Combination Figures 1-4 The vehicle's gas storage tank assembly 100 includes a tank body 10, which has a receiving cavity for containing pressurized gas. The tank body 10 can be made of composite material and possesses good pressure-bearing capacity, thus ensuring the structural stability of the tank body 10. The main body of the tank body 10 can be approximately cylindrical, and the end faces of the tank body 10 can be approximately spherical, as shown in the attached figure. Of course, the shape of the tank body 10 is not limited to this; for example, it can be approximately cuboid. In this case, the shape of the receiving cavity of the tank body 10 can be the same as the shape of the tank body 10.

[0032] Further integration Figure 3 as well as Figure 4The vehicle's air tank assembly 100 is also provided with a partition 20, which is disposed in the accommodating cavity. The partition 20 extends along the axial direction of the tank body 10 and divides the accommodating cavity into a first air chamber 11, a second air chamber 12, and a third air chamber 13 that extend along the axial direction of the tank body 10 and are not interconnected.

[0033] Specifically, the partition 20 and the tank body 10 can be made of the same material. The partition 20 can be fixed to the inner wall of the tank body 10 by welding or other methods, thus placing the partition 20 within the accommodating cavity. In some applications, two shells can be installed, with the partition 20 placed within either shell or within one shell. The two shells can then be welded together to form a complete tank body 10, in which case the partition 20 is also located within the tank body 10. The partition 20 extending axially along the tank body 10 is essentially arranged along its length. In this case, the partition 20 can be roughly strip-shaped, with its length aligned with the length of the tank body 10. The two ends of the partition 20 can then be connected to the inner walls at both ends of the tank body 10. Since the partition 20 extends axially in the tank body 10, the air chambers formed by the partition 20 also extend axially in the tank body 10. That is, the first air chamber 11, the second air chamber 12, and the third air chamber 13 extend axially in the tank body 10, meaning that the length directions of the first air chamber 11, the second air chamber 12, and the third air chamber 13 are consistent with the length direction of the air tank. The first air chamber 11, the second air chamber 12, and the third air chamber 13 are not interconnected. Therefore, the first air chamber 11, the second air chamber 12, and the third air chamber 13 can store gases of different pressures respectively, thereby meeting the air supply pressure requirements of different vehicle devices.

[0034] Figure 5 yes Figure 2 The side view of the structure shown. Figure 6 yes Figure 1 An enlarged structural diagram of region A in the diagram.

[0035] Combination Figure 5 as well as Figure 6 The vehicle's air tank assembly 100 also includes an exhaust valve 30, which is located at one end of the tank body 10 and is used to communicate with the first air chamber 11, the second air chamber 12 and the third air chamber 13 to exhaust gas.

[0036] It should be understood that the exhaust valve 30 is located at one end of the tank 10 to facilitate the arrangement of the valve body 302 and related pipelines. The number of exhaust valves 30 can be one or more; this embodiment does not impose a specific limitation on this. One end of the exhaust valve 30 is connected to the air chamber, and the other end of the exhaust valve 30 can be connected to one end of an external air pipe, and the other end of the air pipe can be connected to the air-using device on the vehicle. When the exhaust valve 30 is open, the gas in the air chamber can be directly introduced into the air-using device through the exhaust valve 30 and the air pipe.

[0037] In summary, the vehicle air tank assembly 100 provided in the above embodiments divides the accommodating cavity of the tank body 10 into multiple independent air chambers through the partition 20, thereby realizing the integration of multiple independent air chambers. Compared with the method of setting multiple air tanks, it simplifies the setting of the air storage structure and the pipeline layout, and reduces the space occupied by the air storage structure.

[0038] Combination Figure 3 In some specific embodiments, the partition 20 includes a first partition 21, a second partition 22 and a third partition 23. The first partition 21, the second partition 22 and the inner wall of the tank 10 form a first air cavity 11. The first partition 21, the third partition 23 and the inner wall of the tank 10 form a second air cavity 12. The second partition 22, the third partition 23 and the inner wall of the tank 10 form a third air cavity 13.

[0039] Specifically, the first partition 21 is connected to the second partition 22, the first partition 21 is connected to the third partition 23, and the second partition 22 is connected to the third partition 23. Therefore, the first partition 21, the second partition 22, and the third partition 23 are actually interconnected. In this case, one side of the first partition 21, the second partition 22, and the third partition 23 in the width direction can be connected, and the other side can be connected to the inner wall of the tank 10, thereby forming the first air chamber 11, the second air chamber 12, and the third air chamber 13. In this case, the two ends of the first partition 21, the second partition 22, and the third partition 23 in the length direction can be connected to the inner walls at both ends of the tank 10, respectively.

[0040] In conjunction with the above, in some specific embodiments, the first partition 21, the second partition 22, and the third partition 23 are interconnected at the axial position of the tank body 10, so that the first air chamber 11, the second air chamber 12, and the third air chamber 13 have the same shape and size. In this case, one side of the first partition 21, the second partition 22, and the third partition 23 in the width direction is interconnected at the axial position of the tank body 10, resulting in an included angle of 60° between the two partitions 20, thus ensuring that the first air chamber 11, the second air chamber 12, and the third air chamber 13 have the same shape and size. Based on this arrangement, the structure of the partition 20 is more stable, and the overall structure of the tank body 10 is more stable.

[0041] Figure 7 This is another way of setting up partition 20.

[0042] Combination Figure 7The arrangement of the partition 20 is not limited to the above-described manner. In some specific embodiments, the partition 20 may consist only of a first partition 21 and a second partition 22. The side of the first partition 21 is connected to the inner wall of the tank 10, and the two opposite sides of the second partition 22 are respectively connected to the inner wall of the tank 10 and the side wall of the first partition 21. The first partition 21 and the inner wall of the tank 10 enclose a first air chamber, and the first partition 21, the second partition 22, and the inner wall of the tank 10 enclose a second air chamber and a third air chamber.

[0043] It should be understood that in this embodiment, the accommodating cavity is divided into three sections by two partitions 20, reducing the number of partitions 20 used. The side of the first partition 21 is connected to the inner wall of the tank 10; that is, the two side walls of the first partition 21 in its width direction are respectively connected to the inner wall of the tank 10. The two opposite sides of the second partition 22 can be the two side sections of the second partition 22 in its width direction. In this case, the two ends of the first partition 21 and the second partition 22 in their length direction can be respectively connected to the inner walls at both ends of the tank 10.

[0044] Given that the partition 20 only includes the first partition 21 and the second partition 22, in some specific embodiments, the volume of the first air chamber is larger than the volume of the second air chamber, and the volume of the second air chamber is larger than the volume of the third air chamber. Therefore, the volumes of the first, second, and third air chambers are not the same, thus meeting the air consumption requirements of different devices.

[0045] Combination Figure 5 as well as Figure 6 In some specific embodiments, the air outlet valve 30 includes a first air outlet valve 31, a second air outlet valve 32, and a third air outlet valve 33. The first air outlet valve 31 is connected to the first air chamber 11, the second air outlet valve 32 is connected to the second air chamber 12, and the third air outlet valve 33 is connected to the third air chamber 13. By setting three air outlet valves 30, each corresponding to one of the three air chambers, individual control of the air chambers can be achieved.

[0046] Regarding the specific configuration of the air outlet valve 30, in some specific embodiments, the air outlet valve 30 includes a control module 301 and a valve body 302. The control module 301 is connected to the valve body 302, and the valve body 302 is connected to the air chamber. The control module 301 is used to control the opening degree of the valve body 302 to control the flow rate of air guided outward from the air chamber.

[0047] The control module 301 can be an electronic control module, and the valve body 302 can be an electronic valve. The control module 301 is connected to the controller, which can then control the electronic control module 301, thereby controlling the valve body 302 and the opening degree of the exhaust valve 30.

[0048] Of course, in other embodiments, the control module 301 for the three exhaust valves 30 can be one, so that the control of the three valve bodies 302 can be achieved through one control module 301, thereby simplifying the structure.

[0049] To enhance the structural strength of the tank 10, in some specific embodiments, a carbon fiber winding layer is provided on the surface of the tank 10. This carbon fiber winding layer is formed by winding carbon fiber filaments along a target direction on the surface of the tank 10, with the target direction forming a preset angle with the axial direction of the tank 10. The carbon fiber filaments can be those found in the prior art, and they are wound using a winding machine to form a dense carbon fiber layer. During the winding process, the carbon fiber filaments can maintain a certain angle with the axial direction of the tank 10, which is a preset angle, for example, 55°. This winding method allows for the formation of a relatively dense carbon fiber layer, thereby effectively strengthening the structure of the tank 10.

[0050] In some applications, the use of carbon fiber layers increases the axial bending stiffness of the tank 10 to 1.8 times that before winding. Of course, the specific value of the stiffness increase can be obtained through the specific winding process of the carbon fiber filaments and the number of winding layers.

[0051] In some specific embodiments, the outer wall of the tank 10 includes a support connection area for connecting with a support. The thickness of the carbon fiber winding layer in the support connection area is greater than the thickness of the carbon fiber winding layer on other outer walls of the tank 10.

[0052] To secure the tank 10, it is typically connected to a bracket, creating a bracket connection area, which can be multiple. In this connection area, the tank 10 wall requires higher structural strength to prevent unnecessary damage. Therefore, this embodiment increases the thickness of the carbon fiber winding layer in the connection area, thereby strengthening the connection area. In practice, more layers of carbon fiber can be wound in the connection area, resulting in a thicker carbon fiber winding layer.

[0053] A second aspect of this application provides a vehicle including an air tank assembly 100 as described in any of the above embodiments and an air supply device, wherein the air tank assembly and the air supply device supply air to the air supply device. For a detailed description of the air tank assembly 100, please refer to the relevant content of the above embodiments; no specific limitations are imposed here.

[0054] In summary, based on the vehicle air tank assembly 100 and the vehicle provided in this application, the vehicle air tank assembly 100 includes: a tank body 10, which has a receiving cavity; a partition 20, which is disposed within the receiving cavity and extends axially along the tank body 10, dividing the receiving cavity into a first air chamber 11, a second air chamber 12, and a third air chamber 13 that extend axially along the tank body 10 and are not interconnected; and an exhaust valve 30, which is disposed at one end of the tank body 10 and is used to communicate with the first air chamber 11, the second air chamber 12, and the third air chamber 13 to exhaust gas. Therefore, by dividing the receiving cavity of the tank body 10 into multiple independent air chambers through the partition 20, the integration of multiple independent air chambers is achieved, thereby simplifying the air storage structure and pipeline layout, and reducing the space occupied by the air storage structure.

[0055] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
