[0035] Reference Figure 1 and Figure 2 A protective structure for a gas storage device, the gas storage device includes a gas storage tank 10, specifically, the protective structure includes a support baffle 20, and the support baffle 20 includes:

[0036] The edge support portion 21 is distributed along the contour of the inner wall from the middle to the bottom of the gas storage tank 10 and is connected to the inner wall of the gas storage tank 10. Specifically, the edge support portion 21 is connected to the inner wall of the tank body by plug welding;

[0037] The hollow portion 22 is provided in the middle of the support baffle 20 to ensure the structural strength of the gas storage tank 10 to the greatest extent while preventing the support baffle 20 from occupying the gas storage space as much as possible;

[0038] The middle connecting portion is located between the two edge supporting portions 21 and is used to connect the edge supporting portions 21 on both sides. The middle connecting portion is distributed in the middle upper part and the bottom of the gas storage tank 10;

[0039] There are several support baffles 20 arranged in a circular array with the central axis of the gas storage tank 10 as the axis. Specifically, there are three support baffles 20 arranged in a circular array with the central axis of the gas storage tank 10 as the axis, so that the angles between the support baffles 20 are acute angles, and the middle connecting parts of each support baffle 20 are connected to each other, so that a fan-shaped area 30 is formed between the support baffle 20 and the inner wall of the gas storage tank 10, such as Figure 5 As shown, if the impact force from the side of the gas tank 10 is concentrated on the middle of a support baffle 20, for example Figure 5 F1 in the figure, then a fan-shaped area 30 ( Figure 5 The black bold dashed line in the middle is ), so that the area where the gas storage tank 10 is impacted forms an arched structure to enhance the structural strength of the side wall of the gas storage tank 10, such as Figure 6 In F2, the impact force is concentrated on the portion between the two support baffles 20. Then, the support baffles 20 on both sides of this region and the side walls of the gas storage tank 10 in this region form a fan-shaped region 30, so that the region where the gas storage tank 10 is impacted forms an arched structure to enhance the structural strength of the side walls of the gas storage tank 10.

[0040] Based on the above structure, the middle connection part located in the middle and upper part of the gas storage tank 10 is the first connection part 23; the middle connection part located at the bottom of the gas storage tank 10 is the second connection part 24; the strength of the support baffle 20 can be improved, and there is an arc edge on the first connection part 23, and the arc edge includes a first arc edge 231 and a second arc edge 232; the first arc edge 231 is located on the upper side of the middle connection part, and the second arc edge 232 is located on the lower side of the middle connection part, which can make the connection between the connection part and the inner wall of the gas storage tank 10;

[0041] The radius of the first arc edge 231 is greater than the radius of the second arc edge 232. The first arc edge 231 can increase the contact area between the support baffle 20 and the intake air flow when the gas is filled, so as to reduce the pressure of the air flow on the support baffle 20, and can better cope with the impact flow caused by the high-pressure gas when the high-pressure gas is injected, thereby reducing the loss of the support baffle 20.

[0042] Based on the above structure, the arc edge of the first arc edge 231 has a double-edged blade structure; and from the arc edge of the second arc edge 232, the edge of the edge support portion 21 to the upper edge of the second connecting portion 24, there is a continuous double-edged blade structure, so that when the gas tank is filled with gas or when the gas is discharged, the airflow can flow out more smoothly along the blade structure, reducing the influence of the support baffle 20 on the airflow.

[0043] Based on further improvement of the above structure, the vertical height of the middle connecting part at the bottom of the gas tank 10 is gradually decreased from the inner wall of the gas tank 10 to the middle of the gas tank 10, which can achieve maximum support for the inner wall of the gas tank 10.
