Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a disassembly and assembly component, a vehicle, and a hydrogen storage module exchange station. Background Technology

[0002] In recent years, awareness of mitigating the global greenhouse effect has increased, particularly in order to reduce carbon dioxide emissions from vehicles. This has led to the widespread development of hydrogen-powered vehicles, such as fuel cell vehicles and hydrogen engine vehicles. These vehicles are generally equipped with hydrogen storage modules filled with hydrogen as a hydrogen supply source. Currently, refillable hydrogen storage modules are commonly used; when hydrogen is insufficient, the vehicle is driven to a hydrogen refueling station for refueling. However, if large commercial vehicles with high hydrogen consumption (such as heavy-duty trucks) use refillable hydrogen storage modules, there is a problem of excessively long refueling times, which affects commercial efficiency. Therefore, the use of exchangeable hydrogen storage modules is being considered to shorten refueling time.

[0003] When the hydrogen storage module is removed from the vehicle, if the hydrogen remaining in the gas supply line is not completely consumed, there is a problem of hydrogen gas with a pressure higher than atmospheric pressure being ejected. This will not only impact the parts where the hydrogen storage module is connected to the vehicle, but also generate a lot of noise, thus seriously affecting the service life of the parts and the user experience. Summary of the Invention

[0004] To address the aforementioned technical problems in the prior art, this application provides a disassembly and assembly component, a vehicle, and a hydrogen storage module exchange station, which can release hydrogen from the gas supply line through a pressure relief line before exchanging the hydrogen storage module, thereby avoiding the problem of hydrogen with a pressure higher than atmospheric pressure being directly ejected when the hydrogen storage module is removed from the vehicle.

[0005] This application provides a disassembly / reassembly assembly for use in a vehicle equipped with an exchangeable hydrogen storage module. The assembly includes a coupler, an intake pipe, and a pressure relief pipe. The coupler is used to interface with the exchangeable hydrogen storage module. One end of the intake pipe is connected via the coupler to the supply pipe of the exchangeable hydrogen storage module, and the other end is connected to the vehicle, for introducing hydrogen from the exchangeable hydrogen storage module into the vehicle. The pressure relief pipe has a pressure relief valve, one end of which is connected to the intake pipe, for releasing hydrogen from the supply pipe before exchanging hydrogen with the exchangeable hydrogen storage module.

[0006] In some embodiments, the other end of the pressure relief line faces an external opening.

[0007] In some embodiments, the disassembly assembly further includes a storage unit for storing the released hydrogen gas, the other end of the pressure relief pipeline being connected to the storage unit.

[0008] In some embodiments, the disassembly assembly further includes a recycling interface that can be connected to a recycling device at the exchange station for introducing the released hydrogen into the exchange station.

[0009] In some embodiments, the pressure relief valve is an electrically controlled valve or a manually operated valve.

[0010] In some embodiments, the disassembly assembly further includes a control unit for controlling the opening and closing of the pressure relief valve.

[0011] In some embodiments, the disassembly / assembly assembly further includes a communication unit for receiving control commands.

[0012] In some embodiments, the control unit controls the opening and closing of the pressure relief valve according to preset conditions.

[0013] This application also provides a vehicle, including the above-described disassembly and assembly components.

[0014] This application embodiment also provides a hydrogen storage module exchange station, including: a recovery device, which can be connected to the recovery interface of the above-mentioned exchangeable hydrogen storage module for recovering the released hydrogen.

[0015] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: by connecting the pressure relief pipe to the intake pipe, hydrogen in the supply pipe can be discharged through the pressure relief pipe before the hydrogen storage module is replaced, so that the unconsumed hydrogen in the supply pipe can be released in advance, avoiding the problem of hydrogen with pressure higher than atmospheric pressure being sprayed out when the hydrogen storage module is removed from the vehicle. This will not impact the parts at the joint between the exchangeable hydrogen storage module and the disassembly and assembly components, and can avoid generating large noise, improving the service life of the parts and the user experience.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0030] This application provides a detachable assembly 100 for use in vehicles equipped with an exchange-type hydrogen storage module 200. The vehicle can be a heavy-duty truck or other large commercial vehicle; this application does not specifically limit its application to this type.

[0031] The aforementioned vehicle can be installed and removed from the exchangeable hydrogen storage module 200 via the disassembly and assembly component 100. The exchangeable hydrogen storage module 200 has both an installed state on the vehicle and a detached state. (Combined with...) Figure 1 and Figure 2 , Figure 1 The exchangeable hydrogen storage module 200 shown is in the installed state. Figure 2 The exchangeable hydrogen storage module 200 shown is in a disassembled state. In scenarios where the vehicle is driving normally and has sufficient hydrogen, requiring no replacement of the hydrogen storage module, the exchangeable hydrogen storage module 200 is in an installed state. This installed state can be understood as the module being stably installed on the vehicle. In scenarios where the vehicle requires hydrogen storage module replacement, such as when the hydrogen in the exchangeable hydrogen storage module 200 needs to be replenished through exchange, or when the vehicle is at a hydrogen exchange station, the exchangeable hydrogen storage module 200 is in a disassembled state. This disassembled state can be understood as the exchangeable hydrogen storage module 200 being removed from the vehicle to allow a new exchangeable hydrogen storage module 200 to be installed on the vehicle.

[0032] like Figure 3As shown, the disassembly / assembly assembly 100 includes a coupler 8, an intake pipe 7, and a pressure relief pipe 4. The coupler 8 is used to connect to the exchange-type hydrogen storage module 200. One end of the intake pipe 7 is connected to the supply pipe 2 of the exchange-type hydrogen storage module 200 via the coupler 8, and the other end of the intake pipe 7 is connected to the vehicle. The intake pipe 7 is used to introduce hydrogen from the exchange-type hydrogen storage module 200 into the vehicle. The pressure relief pipe 4 has a pressure relief valve 41. One end of the pressure relief pipe 4 is connected to the intake pipe 7, and the pressure relief pipe 4 is used to release the hydrogen in the supply pipe 2 before exchanging the hydrogen in the exchange-type hydrogen storage module 200. In this way, the hydrogen in the supply pipe 2 can be quickly discharged through the pressure relief pipe 4 connected to the intake pipe 7, solving the problem of excessive hydrogen residue in the supply pipe 2.

[0033] The aforementioned gas supply line 2 and gas inlet line 7 are detachably connected via a coupler 8, which allows the gas supply line 2 and gas inlet line 7 to be connected or disconnected, enabling rapid exchange of hydrogen storage modules.

[0034] The aforementioned exchangeable hydrogen storage module 200 can be understood as a hydrogen storage module that can be exchanged as a whole to provide sufficient hydrogen as fuel for the vehicle in a timely manner. Using this exchangeable module achieves rapid hydrogen replenishment, effectively shortening the hydrogen replenishment time compared to a refillable hydrogen tank.

[0035] The aforementioned exchangeable hydrogen storage module 200 may include one or more hydrogen storage tanks 1, which may be connected in series or parallel. This application does not specifically limit the construction of the hydrogen storage module; the module only needs to be able to hold sufficient hydrogen. Figure 5 As shown in the figure, a hydrogen storage tank 1 is shown for illustration only and is not intended to be a specific limitation on the number of hydrogen storage tanks 1 included in the hydrogen storage module.

[0036] The opening of the aforementioned hydrogen storage tank 1 may be equipped with an on / off valve. When the on / off valve is opened, it releases hydrogen gas from the hydrogen storage tank 1, and when it is closed, it stops releasing hydrogen gas from the hydrogen storage tank 1.

[0037] like Figure 3 As shown, the aforementioned gas supply line 2 is used to transport hydrogen. Specifically, it transports the hydrogen from the hydrogen storage module to the intake line 7 within the disassembly and assembly assembly 100 on the vehicle where the hydrogen storage module is installed. The hydrogen is then transported via the intake line 7 within the disassembly and assembly assembly 100 to the power system 10, such as a fuel cell system, to provide sufficient hydrogen fuel for the vehicle's power system 10. The gas supply line 2 can be connected to the disassembly and assembly assembly 100 via a coupler 8. The hydrogen in the gas supply line 2 can be released before the hydrogen storage module is replaced to reduce the impact on the joint components when the gas supply line 2 is disconnected from the disassembly and assembly assembly 100.

[0038] The aforementioned hydrogen storage module is an exchangeable module that enables rapid hydrogen replenishment, effectively shortening the hydrogen replenishment time compared to a filler hydrogen tank.

[0039] The scenario described above, before the hydrogen storage module is replaced, can be understood as a situation where the replacement of the hydrogen storage module has been determined but has not yet occurred. At this time, the exchangeable hydrogen storage module 200 has stopped supplying hydrogen, and there is unused hydrogen in the gas supply line 2. Before the exchangeable hydrogen storage module 200 is replaced, the pressure relief line 4 is switched from the closed state to the open state, which can effectively discharge the hydrogen in the gas supply line 2 and avoid impact on the parts at the hydrogen connection points in the gas supply line 2 during the subsequent replacement of the hydrogen storage module.

[0040] The aforementioned pressure relief line 4 cannot release hydrogen from the gas supply line 2 when it is closed, but it can release hydrogen from the gas supply line 2 when it is open. When the hydrogen storage module supplies hydrogen to the power system 10 through the gas supply line 2, the pressure relief line 4 is in the closed state; before the hydrogen storage module is replaced, i.e., when it is determined that the hydrogen storage module needs to be replaced, but the replacement has not yet occurred, the pressure relief line 4 switches from the closed state to the open state.

[0041] After the aforementioned pressure relief pipeline 4 releases hydrogen from the gas supply pipeline 2, it can be understood that the gas pressure in the gas supply pipeline 2 can be reduced to atmospheric pressure.

[0042] The aforementioned gas supply pipeline 2 and gas inlet pipeline 7 may each include multiple pipelines connected in sequence, or they may be a single complete pipeline. This application does not make any specific limitations on this, as long as they can stably transport hydrogen.

[0043] This application, through a pressure relief pipe 4 connected to the intake pipe 7, enables the release of hydrogen in the supply pipe 2 before the hydrogen storage module is replaced. This allows unconsumed hydrogen in the supply pipe 2 to be released in advance, avoiding the problem of hydrogen with a pressure higher than atmospheric pressure being ejected when the exchangeable hydrogen storage module 200 is removed from the vehicle. This prevents impact on the parts at the joint between the exchangeable hydrogen storage module 200 and the disassembly / removal assembly 100, and avoids the problem of excessive noise caused by hydrogen release during the replacement of the hydrogen storage module. This improves the service life of the parts and the user experience.

[0044] In some embodiments, such as Figure 3 and Figure 5 As shown, the other end of the pressure relief pipe 4 opens to the outside. This "opening to the outside" can be understood as facing the outside of the disassembly assembly 100, to prevent hydrogen from remaining inside the disassembly assembly 100 and causing safety hazards. This allows the hydrogen in the gas supply pipe 2 to be directly released to the outside through the pressure relief pipe 4 after it is opened.

[0045] The fact that the other end of the pressure relief pipe 4 is open to the outside can be understood as meaning that the pressure relief pipe 4 is only connected to the gas supply pipe 2 and has no connection with other structures of the disassembly and assembly assembly 100, so that hydrogen can be discharged through the pressure relief pipe 4 with the other end open to the outside, which facilitates the maintenance or repair of the pipe.

[0046] With the other end of the aforementioned pressure relief pipeline 4 facing outwards, the hydrogen in the gas supply pipeline 2 can be discharged into the external environment or into external equipment; this application does not specifically limit this.

[0047] In some embodiments, such as Figure 4 As shown, the disassembly and assembly assembly 100 further includes a storage unit 9, which is used to store the released hydrogen gas, and the other end of the pressure relief pipeline 4 is connected to the storage unit 9.

[0048] Thus, after the pressure relief pipe 4 is opened to release hydrogen from the intake pipe 7, the hydrogen released by the intake pipe 7 can be stored in the storage unit 9 of the disassembly and assembly assembly 100. This allows the vehicle's power system 10 to utilize the hydrogen stored in the storage unit 9 after the vehicle is started again, thus avoiding the waste of hydrogen and achieving the goal of making full use of hydrogen.

[0049] In some embodiments, the disassembly assembly 100 further includes a recycling interface 12, which can be connected to the recycling device 11 of the exchange station for introducing the released hydrogen into the exchange station.

[0050] In this way, hydrogen in the gas supply pipeline 2 can be recovered through the recovery interface 12 connected to the recovery device 11 of the exchange station, thereby reducing hydrogen waste, realizing the effective use of hydrogen, and also improving the safety of hydrogen utilization.

[0051] The aforementioned exchange station can be understood as a place for exchanging hydrogen storage modules. The exchange station can accommodate multiple exchangeable hydrogen storage modules 200 to provide vehicles with sufficient hydrogen.

[0052] The aforementioned recovery interface 12 can be connected to the vent of the pressure relief pipeline 4. When the hydrogen storage module is exchanged in the exchange station, the recovery interface 12 is connected to the recovery device 11 of the exchange station to discharge the hydrogen in the gas supply pipeline 2 into the recovery device 11.

[0053] In some embodiments, the pressure relief valve 41 is an electrically controlled valve or a manually operated valve.

[0054] When the pressure relief valve 41 is a manual valve, it has the advantages of low cost and easy operation. When the pressure relief valve 41 is an electrically controlled valve, the pressure relief valve 41 switches the pressure relief pipeline 4 between the closed state and the open state based on the control command.

[0055] In some embodiments, the disassembly assembly 100 further includes a control unit for controlling the opening and closing of the pressure relief valve 41.

[0056] In this way, the pressure relief valve 41 can be switched between opening and closing in a timely manner by the control unit. Specifically, the control unit can control the pressure relief pipeline 4 to be switched to the open state in a timely manner before exchanging the hydrogen storage module, so as to release the hydrogen in the gas supply pipeline 2 in a timely manner.

[0057] The aforementioned pressure relief valve 41 is electrically connected to the control unit. The control unit is used to obtain control commands for exchanging hydrogen storage modules and to send pressure relief commands to the pressure relief valve 41 based on the control commands. The pressure relief commands are used to instruct the pressure relief valve 41 to open to release hydrogen in the gas supply line 2 before the hydrogen storage module is exchanged.

[0058] The aforementioned control unit sends control commands to the hydrogen storage module, which enables automated control of the pressure relief valve 41 and allows for precise opening of the pressure relief valve 41 before exchanging the hydrogen storage module.

[0059] The aforementioned vehicles may be equipped with a switch button for exchanging the hydrogen storage module. By triggering this switch button, the user can enable the control unit to receive control commands for exchanging the hydrogen storage module.

[0060] The aforementioned control unit can control the pressure relief valve 41 to switch between opening and closing according to control commands from an external source. These external control commands can be transmitted to the control unit by other devices via a communication unit; this application does not specifically limit the device that generates the control commands.

[0061] In some embodiments, the disassembly assembly 100 further includes a communication unit for receiving control commands.

[0062] In this way, control commands from the outside can be received through the communication unit.

[0063] The aforementioned communication unit may include one or more of the following: Bluetooth module, WIFI module, etc.

[0064] In some embodiments, the control unit controls the pressure relief valve 41 to open and close according to preset conditions. Thus, the control unit can timely control the pressure relief valve 41 to switch between open and closed states according to preset conditions. Specifically, before exchanging the hydrogen storage module, the control unit can timely control the pressure relief pipeline 4 to switch to the open state to release hydrogen from the gas supply pipeline 2.

[0065] The aforementioned preset conditions can be understood as the conditions under which the hydrogen storage module needs to be exchanged. Specifically, the preset conditions may be related to one or more of the following information: the vehicle's driving location, the vehicle's driving time, the remaining amount of hydrogen in the exchangeable hydrogen storage module 200, and the usage time of the exchangeable hydrogen storage module 200, etc.

[0066] For example, if the amount of hydrogen remaining in the exchangeable hydrogen storage module 200 is lower than a preset volume, it indicates that the exchangeable hydrogen storage module 200 needs to be replaced to ensure that the vehicle can continue to operate normally. The control unit sends a control command to replace the hydrogen storage module according to the preset condition, and before determining the replacement of the hydrogen storage module, it can control the pressure relief valve 41 to switch from closed to open to release the hydrogen in the gas supply line 2 in a timely manner.

[0067] For example, when the usage time of the exchangeable hydrogen storage module 200 reaches a preset time, it indicates that the exchangeable hydrogen storage module 200 needs to be replaced in order to ensure that the vehicle can continue to drive normally. The control unit sends a control command for the hydrogen storage module to be replaced according to the preset condition, and before determining the replacement of the hydrogen storage module, it can control the pressure relief valve 41 to switch from closed to open, so as to release the hydrogen in the gas supply line 2 in a timely manner.

[0068] In some embodiments, the control unit includes, according to preset conditions, controlling the opening of the pressure relief valve 41 when the vehicle is parked at a designated location.

[0069] In this way, the pressure relief valve 41 can be opened in time when the vehicle is parked in the designated position to quickly release the hydrogen in the gas supply line 2, so as to avoid the problem of excessive impact caused by hydrogen with pressure higher than atmospheric pressure when exchanging hydrogen storage modules.

[0070] The aforementioned designated location may include at least a place capable of exchanging hydrogen storage modules, such as an exchange station, which may accommodate multiple exchangeable hydrogen storage modules 200 to provide vehicles with sufficient hydrogen.

[0071] This application also provides a vehicle. For example... Figure 5 As shown, the vehicle includes the aforementioned disassembly and assembly component 100. The vehicle also includes the aforementioned exchangeable hydrogen storage module 200. The vehicle may be a heavy-duty truck or other large commercial vehicle, and this application does not specifically limit it to this type.

[0072] Vehicles using the aforementioned disassembly and assembly component 100 can release hydrogen from the supply line 2 via the pressure relief line 4 connected to the intake line 7 before exchanging the hydrogen storage module. This allows unconsumed hydrogen in the supply line 2 to be released in advance, preventing the problem of hydrogen with pressure higher than atmospheric pressure being ejected when the exchangeable hydrogen storage module 200 is removed from the vehicle. This also prevents impact on the parts at the joint between the exchangeable hydrogen storage module 200 and the disassembly and assembly component 100, and avoids the problem of excessive noise caused by hydrogen release during the exchange of the hydrogen storage module. This improves the service life of the parts and the user experience.

[0073] Optionally, the aforementioned gas supply pipeline 2 is equipped with a pressure reducing assembly 3, which is used to reduce the pressure of hydrogen from the hydrogen storage tank 1. Specifically, the pressure reducing assembly 3 may include a pressure reducing valve. The hydrogen stored in the hydrogen storage module is pressure-reduced by the pressure reducing valve before being supplied to the power system 10. The pressure-bearing capacity of the pipeline upstream of the pressure reducing assembly 3 can be greater than that of the pipeline downstream of the pressure reducing assembly 3, to ensure stable hydrogen transportation upstream and downstream of the pressure reducing assembly 3.

[0074] The pressure reducing component 3 may also include a vent valve connected to the pressure reducing valve. When the pressure reducing valve malfunctions, the gas in the pipeline can be released through the vent valve to ensure the safety of the pipeline.

[0075] The aforementioned hydrogen storage module also includes a first discharge pipeline 5 connected in parallel with the gas supply pipeline 2. A temperature sensing device 6 is installed on the first discharge pipeline 5. The temperature sensing device 6 is used to detect the temperature information of the hydrogen in the hydrogen storage module, so that when the temperature information exceeds a preset threshold, the hydrogen in the hydrogen storage module is released through the first discharge pipeline 5.

[0076] In this way, when the temperature information detected by the temperature sensing device 6 indicates that the temperature of the hydrogen in the hydrogen storage module is too high, the hydrogen in the hydrogen storage module can be controlled to be quickly released through the first discharge pipe 5, so as to avoid safety hazards caused by the excessively high temperature of the hydrogen in the hydrogen storage module.

[0077] This application also provides a hydrogen storage module exchange station 300. For example... Figure 6 As shown, the hydrogen storage module exchange station 300 includes a recovery device 11, which can be connected to the recovery interface 12 of the aforementioned exchangeable hydrogen storage module 200 for recovering the released hydrogen.

[0078] In this way, hydrogen in the gas supply pipeline 2 can be recovered through the recovery interface 12 connected to the recovery device 11 of the exchange station, thereby reducing hydrogen waste, realizing the effective use of hydrogen, and also improving the safety of hydrogen utilization.

[0079] The aforementioned exchange station can be understood as a place for exchanging hydrogen storage modules. The exchange station can accommodate multiple exchangeable hydrogen storage modules 200 to provide vehicles with sufficient hydrogen.

[0080] The aforementioned recovery interface 12 can be connected to the vent of the pressure relief pipeline 4. When the hydrogen storage module is exchanged in the exchange station, the recovery interface 12 is connected to the recovery device 11 of the exchange station to discharge the hydrogen in the gas supply pipeline 2 into the recovery device 11.
