Compared with traditional gasoline vehicles, hydrogen fuel cell vehicles have the advantages of zero emissions, high efficiency, and long driving range. Hydrogen is a renewable energy source that can be produced through methods such as electrolysis of water or natural gas reforming, so the use of hydrogen fuel cell vehicles will not pollute the environment. In addition, the fuel cell energy density of hydrogen fuel cell vehicles is high, which can provide a longer driving range, and the hydrogen refueling time is short, which brings a more convenient car experience to the driver.

[0003] The hydrogen system and hydrogen frame device are arranged behind the cab of the hydrogen heavy truck, and a sealing plate is installed on the outside of the hydrogen frame. However, the existing hydrogen frame sealing plate structure has the following problems during use:

[0004] ① At present, most products on the market use a screw-connected structure for the sealing plate, and both the bottle head valve and the bottle tail valve are equipped with inspection doors. This structure is complex to install, high in cost and low in production efficiency.

[0005] ② The rear of the hydrogen frame is completely screwed with sealing plates. This method is costly, heavy and complex to install.

[0006] ③ The hydrogen frame inspection door is embedded in the frame. This structure has poor appearance and the hydrogen frame needs to be painted twice. This structure has high cost and low efficiency.

[0007] Therefore, it is necessary to provide a new type of hydrogen frame sealing plate structure to solve the above technical problems. Utility Model Content

[0008] The purpose of the utility model is to provide a novel hydrogen frame sealing plate structure to solve the problems raised in the above background technology.

[0009] To achieve the above-mentioned purpose, the utility model solves the above-mentioned technical problems as follows: a new type of hydrogen frame sealing plate structure, including a hydrogen frame, the rear of the hydrogen frame is set as an opening and two rear sealing plates are arranged at the rear of the hydrogen frame, the two rear sealing plates are symmetrically distributed on both sides of the rear opening of the hydrogen frame, the rear sealing plates are welded and fixed to the hydrogen frame frame, and a top sealing plate is arranged on the top of the hydrogen frame, and the top sealing plate is welded and fixed to the hydrogen frame frame.

[0010] As a further solution of the utility model, three right side maintenance sealing plates are arranged on the right side of the hydrogen frame, the three right side maintenance sealing plates are arranged with the same size, and the right side maintenance sealing plates are screwed and fixed to the hydrogen frame frame.

[0011] As a further solution of the utility model, a single right side maintenance sealing plate has 8 fixing points, and a 5 mm gap is arranged between two adjacent right side maintenance sealing plates.

[0012] As a further solution of the present invention, the right side inspection cover plate is specifically a 2.5 mm aluminum plate.

[0013] As a further solution of the utility model, the upper and lower sides of the right side inspection cover plate are reinforced with U-shaped edges and the frame is bonded to the internal installation point.

[0014] As a further solution of the utility model, the left side of the hydrogen frame is hinged with a left upper inspection door and a left lower inspection door distributed up and down, and the edges of the left upper inspection door and the left lower inspection door are kept flush with the edges of the hydrogen frame skeleton.

[0015] As a further solution of the utility model, three hinges are installed on the left upper inspection door and the left lower inspection door, and two long locks are installed on the left upper inspection door and the left lower inspection door.

[0016] As a further solution of the utility model, the left upper inspection door and the left lower inspection door are provided with a skin, and the skin is specifically made of .mm aluminum plate, and a frame is welded around the inside of the left upper inspection door and the left lower inspection door, and the frame is bonded and fixed to the skin.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. By installing only two rear sealing plates on both sides of the rear of the hydrogen frame, the sealing plate in the middle of the rear of the hydrogen frame is cancelled. This structure can shield the valve pipeline of the hydrogen bottle, while reducing the overall weight of the hydrogen frame, reducing the load, and canceling the screw installation of the entire sealing plate, making the installation simpler and more convenient, and improving the installation efficiency. Since the maintenance frequency of the hydrogen system bottle tail valve is low, three right-side maintenance sealing plates of the same size are fixed on the right side of the hydrogen frame by screws, which can save costs and facilitate installation.

[0019] 2. Due to the high maintenance frequency of the hydrogen system bottle head valve, two left upper inspection doors and left lower inspection doors of the same size are hingedly installed on the side of the hydrogen system bottle head valve to facilitate later maintenance and repair. At the same time, by setting the size of the left upper inspection door and the left lower inspection door to be the same as the outer contour of the hydrogen frame, when the left upper inspection door and the left lower inspection door are closed, the left upper inspection door and the left lower inspection door can completely cover the contour edge of the hydrogen frame, and the contour edge of the hydrogen frame does not need to be painted. When performing the surface treatment of the painting, it is only necessary to paint the outer surfaces of the left upper inspection door and the left lower inspection door, eliminating the operation of repainting the contour edge of the hydrogen frame, and avoiding the need for secondary painting of the contour edge of the hydrogen frame due to the sealing plate being embedded in the hydrogen frame in the prior art, thereby reducing the overall painting workload.

[0027] The present invention will be further described below in conjunction with the embodiments.

[0028] See also Figure 1-4 The utility model provides a novel hydrogen frame sealing plate structure, including a hydrogen frame 8, the rear of the hydrogen frame 8 is set to be an opening and the rear of the hydrogen frame 8 is provided with two rear sealing plates 1, the two rear sealing plates 1 are symmetrically distributed on both sides of the rear opening of the hydrogen frame 8, the rear sealing plate 1 is welded and fixed to the hydrogen frame 8 skeleton, and a top sealing plate 3 is arranged on the top of the hydrogen frame 8, and the top sealing plate 3 is welded and fixed to the hydrogen frame 8 skeleton; since there is no sealing requirement for the sealing plate in the hydrogen frame 8, only two rear sealing plates 1 are installed on both sides of the rear of the hydrogen frame 8, thereby eliminating the sealing plate in the middle of the rear of the hydrogen frame 8. Through this structure, the valve pipeline of the hydrogen bottle can be shielded, and at the same time, the overall weight of the hydrogen frame 8 is reduced, the load is reduced, and the screw connection installation of the entire sealing plate is eliminated, so that the installation is simpler and more convenient, and the installation efficiency is improved.

[0029] Further Figure 2 and Figure 4As shown, it is worth specifically explaining that three right side maintenance sealing plates 2 are arranged on the right side of the hydrogen frame 8, and the three right side maintenance sealing plates 2 are arranged in the same size. The right side maintenance sealing plates 2 are screwed and fixed to the hydrogen frame 8 frame. A single right side maintenance sealing plate 2 has 8 fixing points, and a 5mm gap is arranged between two adjacent right side maintenance sealing plates 2. The right side maintenance sealing plate 2 is specifically a 2.5mm aluminum plate, and the upper and lower sides of the right side maintenance sealing plate 2 are reinforced with U-shaped edges and the internal installation point is bonded to the frame; due to the low frequency of maintenance of the hydrogen system bottle tail valve, three right side maintenance sealing plates 2 of the same size are fixed on the right side of the hydrogen frame 8 by screws, which can save costs and facilitate installation.

[0030] Further Figure 1 and Figure 2 As shown, it is worth explaining in detail that the left side of the hydrogen frame 8 is hinged with a left upper inspection door 4 and a left lower inspection door 5 which are distributed up and down, and the edges of the left upper inspection door 4 and the left lower inspection door 5 are kept flush with the edge of the hydrogen frame frame, and three hinges 6 are installed on the left upper inspection door 4 and the left lower inspection door 5, and two long locks 7 are installed on the left upper inspection door 4 and the left lower inspection door 5. The left upper inspection door 4 and the left lower inspection door 5 are provided with skins, and the skins are specifically made of 2.5mm aluminum plates, and the left upper inspection door 4 and the left lower inspection door 5 are welded with skeletons around the inside, and the skeletons are bonded and fixed to the skins; due to the high frequency of maintenance of the hydrogen system bottle head valve, two large and small hinges are hingedly installed on the hydrogen system bottle head valve side.

Since the maintenance frequency of the hydrogen system bottle tail valve is low, three right-side maintenance sealing plates 2 of the same size are fixed by screws on the right side of the hydrogen frame 8, which can save costs and facilitate installation. Since the maintenance frequency of the hydrogen system bottle head valve is high, two left upper maintenance doors 4 and The left lower inspection door 5 is convenient for later maintenance and repair. At the same time, by setting the size of the left upper inspection door 4 and the left lower inspection door 5 to be the same as the outer contour of the hydrogen frame 8, when the left upper inspection door 4 and the left lower inspection door 5 are closed, the left upper inspection door 4 and the left lower inspection door 5 can completely cover the contour edge of the hydrogen frame 8, and the contour edge of the hydrogen frame 8 does not need to be painted. When the surface is treated by painting, it is only necessary to paint the outer surfaces of the left upper inspection door 4 and the left lower inspection door 5, eliminating the operation of repainting the contour edge of the hydrogen frame 8, avoiding the need for secondary painting of the contour edge of the hydrogen frame 8 due to the sealing plate being embedded in the hydrogen frame 8 in the prior art, thereby reducing the overall painting workload.
