DETAILED DESCRIPTION

[0031] The application will be further described below in conjunction with specific embodiments and drawings.

[0032] Example 1

[0033] Reference Figure 1 、 Figure 2 and Figure 3 , a vehicle-mounted hydrogen storage bottle installation frame, comprising a fixed frame 1, a mounting hoop 2, an electric heating element 3 and a hydrogen supply pipeline 5.

[0034] The fixed frame 1 is a frame structure of the main body, used to realize the installation of the hydrogen storage bottle and other components. The fixed frame 1 is provided with a plurality of mounting hoops 2, which are used to realize the clamping and fixing of the hydrogen storage bottle. The fixed frame 1 and the mounting hoop 2 form a bottle body installation position, and the hydrogen storage bottle is placed in the bottle body installation position.

[0035] The outer edge of the bottle body installation position is provided with an electric heating element 3, which is used to heat and warm the hydrogen storage bottle to realize the diffusion of hydrogen. The fixed frame 1 is provided with a hydrogen supply pipeline 5, which is used to transport the hydrogen in the hydrogen storage bottle to the outside of the vehicle for use.

[0036] The fixed frame 1 is a cuboid frame structure formed by welding connection of a transverse rectangular tube 101, a longitudinal rectangular tube 102 and a vertical rectangular tube 103, which is regular in shape to facilitate processing and manufacturing, and is also convenient for fixing in the vehicle. The bottom four corners of the fixed frame 1 are provided with vehicle-mounted bases 104, and bolt long holes are formed on the vehicle-mounted bases 104 to realize the fixation of the overall frame on the vehicle. The top four corners of the fixed frame 1 are provided with lifting rings 106, which facilitate the lifting and transportation of the overall frame.

[0037] Up to three side surfaces of the fixed frame 1 are welded with end face baffles 105, that is, at least one side surface of the fixed frame 1 is left open to realize the utilization of the waste heat of the vehicle battery pack. The waste heat of the battery pack enters the frame from the side opening, heats the hydrogen storage bottle, and then is discharged from the upper opening of the frame.

[0038] The bottom surface of the fixed frame 1 is welded with an end face baffle 105 to support the components in the frame. The height of the fixed frame 1 is less than the height of the hydrogen storage bottle, and the upper part of the fixed frame 1 is also reserved to be open, so as to ensure that the hydrogen storage bottle extends out of the upper opening and forms a hot air outlet.

[0039] The mounting hoop 2 includes a fixed hoop 201 and a movable hoop 202. The fixed hoop 201 is fixed to the bottom of the fixed frame 1 to limit the bottom of the hydrogen storage bottle and avoid excessive shaking of the bottle bottom. The movable hoop 202 is detachably mounted on the top of the fixed frame 1, and the movable hoop 202 tightly locks the upper part of the hydrogen storage bottle to realize the fixation and arrangement of the bottle in the frame.

[0040] The fixed hoop 201 and the movable hoop 202 are both U-shaped structures with side wing plates. The side wing plates of the fixed hoop 201 are welded and fixed on the fixed frame 1, and the side wing plates of the movable hoop 202 are connected to the fixed frame 1 through locking bolts 203. The locking bolts 203 are preferably butterfly bolts, so that tightening the bolts realizes the tight locking of the movable hoop 202 on the hydrogen storage bottle, and loosening the bolts realizes the replacement of the hydrogen storage bottle.

[0041] Similarly, the movable hoop 202 can also be a strap hoop or a ratchet hoop to replace the connection form of the locking bolts 203 in this embodiment.

[0042] The bottle body arrangement position is vertical or horizontal. In this embodiment, the bottle body arrangement position is vertical, but the horizontal bottle body arrangement position can also be used as an alternative solution.

[0043] The electric heating element 3 is a temperature-controlled electric heating element that can detect the temperature of the hydrogen storage tank. It automatically cuts off power and stops heating when the temperature reaches a certain set value, and automatically resumes heating when the temperature drops to the set value. This provides heating protection for the hydrogen storage tank, preventing it from being heated indefinitely and saving energy. The electric heating element 3 can be an electric heating plate, electric heating strip, or electric heating plate. When it is an electric heating plate, it can be a metal electric heating plate, a plastic electric heating plate, or a non-woven fabric electric heating plate.

[0044] The electric heating element 3 has a semi-circular ring structure and is arranged on the side opposite to the cylinder placement position, opening in the direction of the opening. This allows it to heat areas of the hydrogen storage cylinder that are not in contact with the residual heat air, while the windward side of the hydrogen storage cylinder is directly heated by the residual heat air from the fuel cell stack. Similarly, the electric heating element 3 can also have a cylindrical structure.

[0045] The hydrogen supply line 5 includes a quick-connect fitting 501, an inlet line 502, an inlet tee 503, a ring line 504, an outlet tee 505, and a pagoda fitting 506. Several quick-connect fittings 501 are arranged, the number of which is the same as the number of cylinder mounting positions, to enable quick assembly and disassembly of the hydrogen storage cylinder and the line.

[0046] The quick-connect fitting 501 connects to the intake pipe 502, which in turn connects to the annular pipe 504 via the intake tee 503. This means the intake pipe 502 collects hydrogen from a single hydrogen storage tank into the annular pipe 504, where the pressure is consistent, ensuring a stable supply of hydrogen to the vehicle. The annular pipe 504 connects to the outlet fitting 506 via the outlet tee 505, allowing hydrogen to be delivered.

[0047] The intake manifold 502 uses a plastic flexible hose, but a metal flexible hose can also be used as an alternative. The annular manifold 504 uses a metal pipe connection, but a rubber-plastic hose can also be used as an alternative.

[0048] This application's mounting frame incorporates an electric heating element for auxiliary electric heating. When hydrogen is used downstream, the electric heating element is activated to heat the hydrogen storage cylinder, causing the cylinder to release hydrogen for downstream use. Simultaneously, waste heat from the fuel cell stack can be used to heat the hydrogen storage device. The hydrogen storage module uses a standard solid-state hydrogen storage cylinder with a standard cylinder mounting position, equipped with mounting clamps and quick-connect fittings for easy and convenient replacement. The hydrogen supply pipeline has a common pressure; if increased hydrogen storage capacity is required, hydrogen storage cylinders can be directly stacked.

[0049] Example 2

[0050] refer to Figure 4 , Figure 5 and Figure 6 As shown, a vehicle-mounted solid hydrogen storage device includes a solid hydrogen storage cylinder 4, and also includes the vehicle-mounted hydrogen storage cylinder mounting frame of Embodiment 1.

[0051] The solid hydrogen storage bottle 4 is fixed in the bottle body installation position by installing the hoop 2, the locking bolt 203 is tightened in this embodiment, and the solid hydrogen storage bottle 4 is fixed on the fixed frame 1 through the movable hoop 202. The electric heating element 3 is in contact with the solid hydrogen storage bottle 4, and the electric heating element 3 realizes heating of the bottle body after being electrified. The hydrogen supply pipeline 5 is in communication with the solid hydrogen storage bottle 4, and the hydrogen in the bottle body is sent to the gas inlet pipeline 502 through the quick connector 501, all the gas inlet pipelines 502 are uniformly connected to the annular pipeline 504, and then the hydrogen is sent to the vehicle through the pagoda joint 506.

[0052] Workflow of the present application:

[0053] When hydrogen is used, the valve on the solid hydrogen storage bottle 4 is opened, and the electric heating element 3 is started to heat the hydrogen bottle, and the downstream hydrogen is supplied through the hydrogen supply pipeline 5. When the hydrogen bottle is replaced, the quick connector 501 is disassembled, the butterfly nut on the frame is loosened, the hydrogen bottle is taken out to the hydrogen filling device to fill hydrogen, and after being filled, it can be used, or a new hydrogen storage bottle is directly used.

[0054] The foregoing basic examples and each further selected example of the present application can be freely combined to form a plurality of embodiments, all of which are embodiments that can be used and claimed by the present application. In the present application, each selected example can be arbitrarily combined with any basic example and selected example.

[0055] The above only describes the preferred embodiments of the present application and does not limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
