Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and more specifically, to a vehicle. Background Technology

[0002] Currently, hydrogen energy is a new energy source with large reserves, high energy density, and is clean. Vigorously developing the hydrogen energy industry is an important direction for the future low-carbon development of energy utilization. This includes hydrogen production, storage, and utilization, which have become priority industrial chains in the energy planning of countries worldwide. Specifically, with the rapid development of hydrogen energy, the application of fuel cell non-road vehicles is increasing. Taking fuel cell forklifts as an example, although fuel cell forklifts have many advantages, hydrogen refueling is expensive and requires additional refueling equipment. The forklift refueling site needs to meet various regulations, resulting in high initial equipment investment and operating costs. This has led to many problems in the early promotion of fuel cell forklifts, especially in scenarios where only a few forklifts are used for demonstration.

[0003] In the prior art, a mobile refueling device has been proposed to address the aforementioned problems, enabling hydrogen refueling of fuel cell forklifts. However, since the mobile refueling device itself lacks mobility, its hydrogen refueling range is limited. Utility Model Content

[0004] The main objective of this invention is to provide a vehicle that solves the problem of limited hydrogen refueling range in existing mobile refueling devices.

[0005] To achieve the above objectives, this utility model provides a vehicle, comprising: a vehicle body; a power system and a fuel cell, mounted on the vehicle body, the fuel cell being electrically connected to the power system to supply power to the power system; a hydrogen storage structure, mounted on the vehicle body, the hydrogen storage structure having a power supply state connected to the fuel cell for supplying hydrogen to the fuel cell and a hydrogen refueling state for refueling a forklift; and a refueling device, the refueling device being connected to the hydrogen storage chamber of the hydrogen storage structure for delivering the hydrogen stored in the hydrogen storage chamber to the forklift.

[0006] Furthermore, the vehicle body has a driver's cab, a first storage chamber, a second storage chamber, and a placement chamber arranged at intervals. The driver's cab is located in front of the first storage chamber, the second storage chamber, and the placement chamber. The first storage chamber is used for slow hydrogen storage, the second storage chamber is used for buffering and refueling equipment, and the placement chamber is used for installing fuel cells.

[0007] Furthermore, along the vehicle's direction of travel, the first storage compartment is located between the driver's cab and the second storage compartment.

[0008] Furthermore, the first storage chamber and the second storage chamber are separated by a partition made of heat-insulating material.

[0009] Furthermore, the vehicle also includes: a first pipeline through which the hydrogen storage structure is connected to the fuel cell; a first control valve located on the first pipeline for controlling the on / off state of the first pipeline; and a control module electrically connected to both the first control valve and the power system. When the control module detects that the power system is in a running state, it controls the first control valve to open, thereby connecting the first pipeline; when the control module detects that the power system is in a standby or stopped state, it controls the first control valve to close, thereby disconnecting the first pipeline.

[0010] Furthermore, the vehicle also includes: a second pipeline through which the hydrogen storage structure is connected to the refueling equipment; a second control valve located on the second pipeline to control the on / off state of the second pipeline; and a control module electrically connected to both the second control valve and the power system. When the control module detects that the power system is in standby or stopped state, it controls the second control valve to open, thus connecting the second pipeline; when the control module detects that the power system is running, it controls the second control valve to close, thus disconnecting the second pipeline.

[0011] Furthermore, the refueling equipment includes: a hydrogen supply structure; and a compressor connected to both the hydrogen supply structure and the hydrogen storage structure for extracting hydrogen from the hydrogen supply structure and replenishing hydrogen to the hydrogen storage structure.

[0012] Furthermore, the vehicle also includes: a pressure detection device for detecting the hydrogen pressure within the hydrogen storage structure; and a control module electrically connected to both the compressor and the pressure detection device. When the pressure detection device's reading is less than or equal to a preset pressure value, the control module controls the compressor to increase the compression ratio.

[0013] Furthermore, the refueling equipment includes: a hydrogen supply structure; and a booster pump, which is connected to both the hydrogen supply structure and the hydrogen storage structure, for drawing hydrogen from the hydrogen supply structure and replenishing hydrogen to the hydrogen storage structure.

[0014] Furthermore, the vehicle also includes a cooling device located in the second storage compartment for cooling and temperature reduction of the refueling equipment.

[0015] The vehicle, utilizing the technical solution of this utility model, includes a vehicle body, a power system and a fuel cell, a hydrogen storage structure, and a refueling device. The power system and fuel cell are mounted on the vehicle body, with the fuel cell electrically connected to the power system to supply power. The hydrogen storage structure is mounted on the vehicle body and has two states: a power supply state for connecting to the fuel cell to provide hydrogen, and a refueling state for refueling a forklift. The refueling device communicates with the hydrogen storage chamber of the hydrogen storage structure to deliver the hydrogen stored in the chamber to the forklift. Thus, the hydrogen storage structure can provide hydrogen (power) to the vehicle's fuel cell, ensuring the vehicle's mobility, and can also refuel the fuel cell forklift, thereby expanding the hydrogen refueling range and solving the problem of limited hydrogen refueling range in existing mobile refueling devices. This allows the vehicle to refuel forklifts in different locations. Simultaneously, the vehicle is powered by the hydrogen within the hydrogen storage structure, eliminating the need for additional fuel supply and facilitating vehicle maintenance.

[0029] To address the limitation of hydrogen refueling range in existing mobile refueling devices, this application provides a vehicle.

[0030] like Figure 1 As shown, the vehicle includes a body 10, a power system and fuel cell 20, a hydrogen storage structure 30, and a refueling device 40. The power system and fuel cell 20 are mounted on the body 10, and the fuel cell 20 is electrically connected to the power system to supply power. The hydrogen storage structure 30 is mounted on the body 10 and has two states: a power supply state for connecting to the fuel cell 20 to supply hydrogen to the fuel cell 20, and a refueling state for refueling the forklift with hydrogen. The refueling device 40 communicates with the hydrogen storage chamber of the hydrogen storage structure 30 to deliver the hydrogen stored in the hydrogen storage chamber to the forklift.

[0031] By applying the technical solution of this embodiment, the hydrogen storage structure 30 can provide hydrogen (power) to the vehicle's fuel cell 20, ensuring the vehicle's mobility. It can also refuel fuel cell forklifts, thereby expanding the hydrogen refueling range and solving the problem of limited hydrogen refueling range in existing mobile refueling devices. This allows the vehicle to refuel forklifts in different locations. Simultaneously, the vehicle is powered by the hydrogen within the storage structure 30, eliminating the need for additional fuel supply and facilitating vehicle maintenance.

[0032] like Figure 1 As shown, the vehicle body 10 has a driver's cab 11, a first storage chamber 12, a second storage chamber 13, and a placement chamber 14 arranged at intervals. The driver's cab 11 is located in front of the first storage chamber 12, the second storage chamber 13, and the placement chamber 14. The first storage chamber 12 is used for the slow storage of hydrogen structure 30, the second storage chamber 13 is used for the buffer refueling device 40, and the placement chamber 14 is used to install the fuel cell 20. This arrangement makes the internal space layout of the vehicle body 10 more rational and compact, improving the utilization rate of the internal space. Furthermore, since different structures are located in different chambers, when personnel need to repair a structure in a specific chamber, they only need to open that chamber without affecting other structures.

[0033] In this embodiment, the first storage chamber 12 and the second storage chamber 13 are both located above the placement chamber 14, so that the fuel cell 20 is at a lower position on the vehicle body 10, thereby lowering the center of gravity of the vehicle body 10, making the vehicle drive more smoothly and improving the driver's driving experience.

[0034] In this embodiment, the first storage chamber 12 is located between the driver's cab 11 and the second storage chamber 13 along the vehicle's direction of travel. This allows the first storage chamber 12, used for installing the hydrogen storage structure 30, to be centrally located, thus providing good protection for the hydrogen storage structure 30 and improving the overall safety of the vehicle.

[0035] like Figure 1 As shown, the first storage chamber 12 and the second storage chamber 13 are separated by a partition 50, which is made of heat-insulating material. Thus, during the process of the hydrogen storage structure 30 supplying hydrogen to the fuel cell 20, if its surface heats up, the aforementioned arrangement of the partition 50 can protect the refueling device 40 installed in the second storage chamber 13, preventing heat transfer into the second storage chamber 13 and damage to the refueling device 40.

[0036] Optionally, the vehicle also includes a first pipeline, a first control valve, and a control module. The hydrogen storage structure 30 is connected to the fuel cell 20 via the first pipeline, and the first control valve is located on the first pipeline to control its on / off state. The control module is electrically connected to both the first control valve and the power system. When the control module detects that the power system is running, it controls the first control valve to open, thus connecting the first pipeline. When the control module detects that the power system is in standby or stopped state, it controls the first control valve to close, thus disconnecting the first pipeline. This configuration allows the control module to control the connection state between the hydrogen storage structure 30 and the fuel cell 20, improving the vehicle's automation and reducing the driver's workload. It also ensures the vehicle has mobility, enabling it to carry the hydrogen storage structure 30 to a predetermined location for hydrogen refueling of the forklift.

[0037] Optionally, the vehicle also includes a second pipeline, a second control valve, and a control module 60. The hydrogen storage structure 30 is connected to the refueling device 40 via the second pipeline, and the second control valve is located on the second pipeline to control its on / off state. The control module 60 is electrically connected to both the second control valve and the power system. When the control module 60 detects that the power system is in standby or stopped state, it controls the second control valve to open, thus connecting the second pipeline; when the control module 60 detects that the power system is running, it controls the second control valve to close, thus disconnecting the second pipeline. This configuration allows the connection state between the hydrogen storage structure 30 and the refueling device 40 to be controlled via the control module, thereby improving the vehicle's automation level and reducing the driver's operational difficulty.

[0038] In this embodiment, when the control module 60 detects that the vehicle is in a driving state (the power system is in a starting state), it controls the first control valve to open and the second control valve to close, so that the first pipeline is in a connected state and the second pipeline is in a disconnected state. At this time, the hydrogen storage structure 30 is connected to the fuel cell 20 through the first pipeline and is in a power supply state. When the control module 60 detects that the vehicle is in a stopped state and hydrogen needs to be refueled in the forklift (the power system is in a standby or stopped state), it controls the first control valve to close and the second control valve to open, so that the first pipeline is in a disconnected state and the second pipeline is in a connected state. At this time, the hydrogen storage structure 30 is connected to the refueling device 40 through the second pipeline and is in a refueling state, thereby refueling the fuel cell forklift with hydrogen.

[0039] Optionally, the refueling device 40 includes a hydrogen supply structure and a compressor. The compressor is connected to both the hydrogen supply structure and the hydrogen storage structure 30 to extract hydrogen from the hydrogen supply structure and replenish hydrogen to the hydrogen storage structure 30. Thus, the hydrogen supply structure replenishes hydrogen to the hydrogen storage structure 30, ensuring that the amount of hydrogen in the storage structure 30 is sufficient to supply hydrogen to the fuel cell 20 and also to meet the hydrogen refueling requirements of the forklift. Simultaneously, the compressor compresses and pressurizes the hydrogen replenished via the hydrogen supply structure to ensure that the hydrogen can smoothly enter the vehicle's fuel cell 20 or the forklift.

[0040] Optionally, the vehicle also includes a pressure detection device and a control module 60. The pressure detection device detects the hydrogen pressure within the hydrogen storage structure 30. The control module 60 is electrically connected to both the compressor and the pressure detection device. When the pressure value detected by the pressure detection device is less than or equal to a preset pressure value, the control module 60 controls the compressor to increase its compression ratio. Thus, when the pressure detection device detects that the hydrogen pressure within the hydrogen storage structure 30 is insufficient to meet the hydrogen supply requirements, the control module 60 controls the compressor to increase its compression ratio, achieving automated control of the hydrogen pressure, improving the vehicle's intelligence, and reducing the driver's operational difficulty.

[0041] Optionally, the refueling device 40 includes a hydrogen supply structure and a booster pump. The booster pump is connected to both the hydrogen supply structure and the hydrogen storage structure 30 to extract hydrogen from the hydrogen supply structure and replenish hydrogen to the hydrogen storage structure 30. Thus, the hydrogen supply structure replenishes hydrogen to the hydrogen storage structure 30, ensuring that the amount of hydrogen in the storage structure 30 is sufficient to supply hydrogen to the fuel cell 20 and also to meet the hydrogen refueling requirements of the forklift. Simultaneously, the booster pump compresses and pressurizes the hydrogen replenished via the hydrogen supply structure to ensure that the hydrogen can smoothly enter the vehicle's fuel cell 20 or the forklift. Furthermore, the above configuration allows for more flexible structural selection of the refueling device 40 to meet different usage needs and operating conditions, and also improves the processing flexibility of the operators.

[0042] like Figure 1 As shown, the vehicle also includes a cooling device 70. The cooling device 70 is located within the second storage chamber 13 and is used to cool and lower the temperature of the refueling device 40. Thus, during the operation of the refueling device 40, the cooling device 70 is used to cool and lower the temperature of the refueling device 40 to prevent the surface temperature of the refueling device 40 from becoming too high and affecting its service life.

[0043] Optionally, the vehicle is a fuel cell light truck.

[0044] In this embodiment, the hydrogen pressure inside the hydrogen storage structure 30 is 35 MPa.

[0045] Optionally, the hydrogen storage structure 30 includes a plurality of hydrogen storage cylinders, which are spaced apart along at least one of the length, height and width directions of the vehicle body 10.

[0046] In this embodiment, there are eight hydrogen storage cylinders with a capacity of 162L each. Each hydrogen storage cylinder holds approximately 33kg of hydrogen. The fuel cell light truck consumes approximately 3kg of hydrogen per 100km. Assuming that the hydrogen refueling station is within 50km of the fuel cell forklift refueling point, the remaining hydrogen available from the hydrogen storage cylinders of the fuel cell light truck is approximately 30kg. Based on a refueling rate of 1kg per fuel cell forklift, this can meet the refueling needs of 30 fuel cell forklifts.

[0047] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0048] The vehicle comprises a body, a powertrain and fuel cell, a hydrogen storage structure, and a refueling device. The powertrain and fuel cell are mounted on the body, with the fuel cell electrically connected to the powertrain to provide power. The hydrogen storage structure is also mounted on the body and has two states: one for supplying hydrogen to the fuel cell and the other for refueling the forklift. The refueling device communicates with the hydrogen storage chamber of the hydrogen storage structure to deliver the stored hydrogen to the forklift. Thus, the hydrogen storage structure can supply hydrogen (power) to the vehicle's fuel cell, ensuring the vehicle's mobility, and can also refuel the fuel cell forklift, thereby expanding the hydrogen refueling range and solving the problem of limited refueling range in existing mobile refueling devices. This allows the vehicle to refuel forklifts in different locations. Furthermore, since the vehicle is powered by hydrogen stored within the hydrogen storage structure, no additional fuel supply is required, facilitating vehicle maintenance.
