Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a wide-body vehicle for hydrogen fuel cells used in mining. Background Art

[0002] Hydrogen fuel cells are power generation devices that convert the chemical energy of hydrogen and oxygen into electrical energy. Hydrogen fuel cells only produce water and heat during the electrochemical reaction and are a clean energy source. With the urgent need for environmental protection, new energy vehicles using hydrogen fuel cells as energy supply devices have developed rapidly.

[0003] The driving range of a hydrogen fuel cell vehicle on a single refueling is significantly greater than that of a pure electric vehicle on a single charge. In addition, the process of refueling a hydrogen fuel cell vehicle with hydrogen is very fast, taking only a few minutes, while a pure electric vehicle takes several hours to charge, so the advantage of hydrogen fuel cell vehicles in waiting time for charging is also obvious.

[0004] In particular, in the field of wide-body mining vehicles, the vehicles are heavily loaded, the working conditions are harsh and they require long hours of operation. Pure electric vehicles cannot meet the usage requirements due to defects such as short cruising range, long charging time, large battery size and weight. Hydrogen fuel cell vehicles can overcome these defects and help the zero-carbon and intelligent development of mining equipment.

[0005] Hydrogen fuel cell mining wide-body vehicles usually include a frame and a hydrogen fuel cell mounted on the frame, a hydrogen storage tank, a drive motor, a power battery, a motor controller system and a cooling system. The hydrogen storage tank is used to supply hydrogen to the hydrogen fuel cell. The hydrogen from the hydrogen storage tank reacts with oxygen from the air in the hydrogen fuel cell stack to generate electricity. The generated electricity is provided to the drive motor to drive the vehicle, or stored in the power battery so that when more power is needed (for example, the vehicle accelerates suddenly, climbs a slope), the power battery and the hydrogen fuel cell together supply power to the drive motor. The motor controller is used to control the rotation speed and direction of the drive motor, etc. The cooling system is used to dissipate heat from the hydrogen fuel cell, the motor controller and other power devices.

[0006] In the existing hydrogen fuel cell mining wide-body vehicles, the layout of various parts is unreasonable. For example, the layout of the motor controller, cooling system, hydrogen fuel cell, hydrogen storage tank, power battery, etc. is unreasonable, which is inconvenient for maintenance, has low work efficiency, and the overall layout is uncoordinated and unsightly.

[0007] Therefore, there is a need to optimize the layout of various parts of a hydrogen fuel cell mining wide-body vehicle. Utility Model Content

[0035] Figures 1 to 3 The optimized layout of the hydrogen fuel cell wide-body mining vehicle 100 of the exemplary embodiment of the present utility model is schematically shown from the top, left side and right side respectively. In a specific embodiment, the hydrogen fuel cell wide-body mining vehicle 100 is a wide-body mining dump truck.

[0036] like Figure 1 and Figure 2 As shown, the hydrogen fuel cell wide-body mining vehicle 100 includes a vehicle frame 1 and a cab 2 and a truck 3 mounted on the vehicle frame 1. As is well known in the art, the vehicle frame 1 may include a front axle 11, a rear axle 12, a left longitudinal beam 13, and a right longitudinal beam 14, the cab 2 is arranged at the front of the vehicle frame 1, and the truck 3 is arranged behind the cab 2.

[0037] like Figures 1 to 3 As shown, the hydrogen fuel cell wide-body mining vehicle 100 further includes a hydrogen fuel cell 4, a hydrogen storage tank 5, a drive motor 6, a power battery 7, a motor controller system 8 and a cooling system 9 mounted on the vehicle frame 1.

The position of the hydrogen fuel cell 4 is close to that of the engine of a conventional fuel vehicle, so it is convenient to retrofit the design based on a conventional fuel vehicle. The arrangement of the hydrogen storage tank 5 between the hydrogen fuel cell 4 and the truck bed 3 in the transverse direction makes the arrangement of the hydrogen storage tank 5 compact. Arranging the hydrogen fuel cell 4 and the hydrogen storage tank 5 at least partially on the upper side of the frame 1 facilitates their maintenance.

[0039] More specifically, if Figure 3 As shown, in a specific embodiment of a wide-body dump truck for mining, the hydrogen storage tank 5 is located in front of a lifting bar 30, and the lifting bar 30 is used to lift the truck body 3 to unload the cargo.

[0040] like Figure 1 As shown, the drive motor 6 is arranged behind the hydrogen fuel cell 4 and close to the hydrogen fuel cell 4, and the power battery 7 is arranged on the left side of the frame 1. Figure 2 As shown, the power battery 7 is arranged on the lower side of the frame 1, but the wading depth requirement of the vehicle should be met. The hydrogen fuel cell 4 supplies power to the drive motor 6 to drive the hydrogen fuel cell wide-body mining vehicle 100, and on the other hand, stores the excess electric energy in the power battery 7, so that when the hydrogen fuel cell wide-body mining vehicle 100 needs more power (such as rapid acceleration or climbing), the power battery 7 and the hydrogen fuel cell 4 supply power to the drive motor 6 together.

The power battery 7 is arranged behind the motor controller 80.

[0043] like Figures 1 to 3 As shown, the cooling system 9 includes a fuel cell cooling subsystem 91 and an electronic cooling subsystem 92. The fuel cell cooling subsystem 91 is used to dissipate heat for the hydrogen fuel cell 4. It is arranged in front of the hydrogen fuel cell 4 and located at the front end of the frame 1. Its air intake surface is in the same direction as the forward direction of the hydrogen fuel cell mining wide-body vehicle 100, so the cooling efficiency is high. In addition, the fuel cell cooling subsystem 91, the hydrogen fuel cell 4 and the hydrogen storage tank 5 are arranged in sequence from front to back in the longitudinal direction. The hydrogen fuel cell 4 is close to the fuel cell cooling subsystem 91 and the hydrogen storage tank 5, so the working efficiency is high.

[0044] The electronic cooling subsystem 92 is used to dissipate heat for the motor controller 80 and other power devices, such as the central controller. The electronic cooling subsystem 92 is arranged on the left side of the frame 1 and is located at the front end of the frame 1. Its air intake surface is in the same direction as the forward direction of the hydrogen fuel cell mining wide-body vehicle 100, so the cooling efficiency is high.

[0045] like Figure 1 As shown, the cooling system 9 also includes a cooling pipeline assembly 93. The cooling pipeline assembly 93 is accommodated in the second shield 82 together with the high and low voltage cables 83. Although not shown in the figure, it can be understood that a part of the high and low voltage cables 83 and the cooling pipeline assembly 93 are accommodated in the first shield 81. By accommodating the cooling pipeline and the cable in the shield, the whole vehicle can be made neater and more beautiful and maintenance is more convenient.

The hydraulic steering system 10 includes a steering motor 15, a steering pump 16 and a hydraulic oil tank 17, all of which are arranged on the right side of the vehicle frame 1. The hydraulic oil tank 17 is arranged on the upper side of the vehicle frame 1 and is located between the hydrogen storage tank 5 and the vehicle bucket 3.

Preferably, the steering motor 15 and the steering pump 16 are substantially opposite to the power battery 7 in the lateral direction.

[0047] like Figure 1 and Figure 3 As shown, the hydrogen fuel cell wide-body mining vehicle 100 further includes a gas tank 20 for braking. The gas tank 20 is arranged on the right side of the vehicle frame 1 and behind the steering motor 15.
