[0060] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0061] like Figures 1 to 2 As shown, this disclosure provides an on-board hydrogen supply system, including: a frame, a tank 2, a delivery pipeline, a detection device, and a display device 5.

[0062] The frame contains an internal space, within which a tank 2 is housed for storing hydrogen. A nozzle is located at one end of the tank 2 along its axis, through which a delivery pipeline connects to the interior of the tank 2 for hydrogen delivery. A detection device is provided to detect at least the parameters of the hydrogen within the tank 2. A display device 5 is mounted on the frame and positioned opposite the nozzle at opposite ends of the tank 2 along its axial direction. The display device 5 is communicatively connected to the detection device to acquire the parameters of the hydrogen within the tank 2.

[0063] Among them, such as Figures 3 to 4 As shown, the display device 5 may include at least a display panel 51 and a portable power supply device 52. The portable power supply device 52 is capable of storing electrical energy and is used to power the display panel 51 so that the display panel 51 can display.

[0064] For example, the portable power supply device 52 can be a fuel cell, a solar charging panel, or other similar device, depending on the specific circumstances.

[0065] In this embodiment of the present disclosure, a movable power supply device 52 is provided in the display device 5 so that the display panel 51 can still display after the on-board hydrogen supply system is removed from the vehicle.

[0066] Specifically, when the on-board hydrogen supply system is installed on a vehicle, it can communicate with the vehicle via wiring harness. This allows the driver or other personnel to obtain the parameters of the hydrogen inside the tank 2 through the vehicle's onboard display screen and other devices, enabling monitoring of the on-board hydrogen supply system. Even after the on-board hydrogen supply system is removed from the vehicle, personnel can still obtain the parameters of the hydrogen inside the tank 2 through the display device 5 on the on-board hydrogen supply system, thus enabling real-time monitoring of the internal conditions of the tank 2.

[0067] In some embodiments, the display device 5 may include a fault code parsing module, which may include modules for normal, alarm, fault, fault diagnosis, etc.

[0068] After detecting the parameters of hydrogen gas in tank 2, the detection equipment can analyze the parameters and display the corresponding analysis results on the display panel 51. When the detection equipment detects abnormal hydrogen gas parameters in tank 2, the display device 5 acquires the abnormal parameters and can automatically display the cause of the abnormality and handling suggestions on the display panel 51 to improve user interactivity.

[0069] For example, when the pressure on the pressure reducing valve in the on-board hydrogen supply system is abnormal, the display panel 51 can automatically display: "Pressure reducing valve pressure is abnormal, it is recommended to check the pipeline connection", so that the staff can understand the abnormal situation in the on-board hydrogen supply system in a timely manner and take appropriate measures.

[0070] In some embodiments, the display panel 51 may have a touch function, allowing users to quickly obtain various parameters by directly touching (e.g., clicking, swiping, zooming) the display screen of the display panel 51, thereby improving the interaction efficiency between the user and the on-board hydrogen supply system.

[0071] In some embodiments, the display panel 51 can realize parameter split-screen display, so as to divide the display screen of the display panel 51 into multiple independent display areas, thereby displaying different content at the same time to meet the needs of different scenarios.

[0072] For example, in this embodiment of the present disclosure, parameters can be displayed in a split-screen manner to simultaneously display the "real-time data mode" and "historical curve mode" of hydrogen parameters in tank 2 on display panel 51.

[0073] In some embodiments, the display device 5 may further include a wireless transmission module, which is capable of communicating with a remote monitoring center to enable remote monitoring of the on-board hydrogen supply system.

[0074] For example, embodiments of this disclosure may integrate Bluetooth and / or Wi-Fi modules within the display device 5 to synchronize data from the on-board hydrogen supply system to a remote mobile terminal, thereby enabling the display device 5 to simultaneously achieve local display and remote monitoring.

[0075] like Figure 1 and Figure 3 As shown, in some embodiments, the display device 5 may further include a housing 53, the housing 53 being hollow and forming an installation space, the display panel 51 and the movable power supply device 52 being disposed within the installation space, and the display panel 51 and the movable power supply device 52 being arranged sequentially along the longitudinal direction Y.

[0076] It should be noted that in this embodiment, the axial direction of the tank 2 is parallel to the longitudinal direction Y.

[0077] The display panel 51 is located on the side of the movable power supply device 52 away from the tank body 2, so that the user can observe the content on the display panel 51.

[0078] This embodiment of the present disclosure, by placing the display panel 51 and the portable power supply device 52 inside the housing 53, can protect the display panel 51 and the portable power supply device 52 by the housing 53, reducing the risk of the display panel 51 and the portable power supply device 52 being exposed to the outside world and being contaminated or damaged, thereby extending the service life of the display panel 51 and the portable power supply device 52.

[0079] In some embodiments, the display device 5 can be detachably mounted on the frame to facilitate the assembly and disassembly of the display device 5 from the frame.

[0080] For example, the display device 5 can be detachably connected to the frame via the housing 53.

[0081] like Figures 1 to 2 As shown, in some embodiments, the frame may include two end frames 11, which are spaced apart along the longitudinal direction Y to form a receiving space for accommodating the tank 2.

[0082] like Figure 1 and Figure 5 As shown, the on-board hydrogen supply system may also include a mounting bracket 15, which is disposed within the end frame 11 and located on the side of the tank 2 near the display device 5. The mounting bracket 15 is box-shaped with an opening facing away from the tank 2, and the two ends of the mounting bracket 15 in the lateral direction X are detachably connected to the end frame 11.

[0083] Specifically, in this embodiment of the present disclosure, the mounting bracket 15 can be located in the upper middle part of the end frame 11, and its opposite ends in the lateral X direction can be detachably connected to the end frame 11 by screws and bolts.

[0084] like Figures 5 to 7 As shown, in some embodiments, the display device 5 is detachably connected to the mounting bracket 15.

[0085] Specifically, the display device 5 can be detachably connected to the mounting bracket 15 via the housing 53.

[0086] like Figure 5 As shown, in some embodiments, the mounting bracket 15 may include a mounting base plate 152 and a mounting side plate 153. The mounting base plate 152 is located between the display device 5 and the mounting side plate 153, and forms a mounting space between the mounting base plate 152 and the mounting side plate 153 to accommodate the display device 5. The housing 53 may be detachably connected to at least one of the mounting base plate 152 and the mounting side plate 153.

[0087] like Figure 3 As shown, in some embodiments, the outer casing 53 may include extension plates 531 at its opposite ends in the transverse direction X. The side of the extension plate 531 near the tank body 2 abuts against the side of the mounting base plate 152 opposite to the tank body 2. The extension plate 531 is provided with a through connection hole, through which connecting structures such as bolts and nuts can pass to fix the display device 5 to the mounting base plate 152.

[0088] like Figure 5 As shown, in some embodiments, heat dissipation holes 155 may be provided on the housing 53 and the mounting bracket 15.

[0089] For example, in embodiments of this disclosure, through-holes 155 may be provided in the mounting base plate 152 and / or mounting side plate 153 to facilitate heat dissipation of the display panel 51 and reduce the risk of damage caused by excessive temperature of the display panel 51.

[0090] like Figure 3 As shown, in some embodiments, the portable power supply device 52 and / or display panel 51 may include a charging port. A through-hole 532 opposite to the charging port may be provided on the housing 53 and mounting bracket 15 to allow wiring to connect to the charging port through the through-hole 532, thereby enabling charging of the portable power supply device 52 and / or display panel 51.

[0091] like Figure 1 and Figure 2 As shown, in some embodiments, the frame may include a top plate 12 and a bottom plate spaced apart, with end frames 11 located at opposite ends of the bottom plate in the longitudinal Y direction and connected to the top surface of the bottom plate near the top plate 12. The tank 2 is placed on the top surface of the bottom plate. The top plate 12 is located on the side of the tank 2 away from the bottom plate, and the top of the end frames 11 extends upward beyond the top plate 12.

[0092] The frame may also include multiple longitudinal beams 13 extending in the longitudinal direction Y and multiple support beams extending in the vertical direction Z. The opposite ends of the support beams in the vertical direction Z are connected to the top plate 12 and the bottom plate, respectively, to support the top plate 12. The opposite ends of the longitudinal beams 13 in the longitudinal direction Y are connected to the end frames 11, and the top surface of the longitudinal beams 13 away from the bottom plate abuts against the bottom surface of the top plate 12 near the bottom plate, thereby supporting the top plate 12.

[0093] In some embodiments, the frame may further include a plurality of crossbeams extending in the transverse direction X, the opposite ends of which may be connected to the connecting beam 151. The plurality of crossbeams may be arranged at intervals in the longitudinal direction Y, and the top surface of the crossbeams away from the bottom plate may abut against the top plate 12 to increase the support strength of the top plate 12 and reduce the risk of bending or deformation of the top plate 12.

[0094] In some embodiments, the top plate 12 may be tilted downwards in the lateral direction X.

[0095] For example, such as Figure 8 As shown, one end of the top plate 12 in the horizontal direction X can be higher than the mounting frame 15, and the other end of the top plate 12 in the horizontal direction X can be inclined downward in the vertical direction Z so that water vapor, impurities and other contaminants can fall off the top plate 12 automatically, reducing the risk of the top plate 12 being contaminated and extending its service life.

[0096] like Figure 5 and Figure 8As shown, in some embodiments, when the height of one end of the top plate 12 near the mounting frame 15 in the transverse X direction is between the top and bottom surfaces of the mounting frame 15, in order to reduce the interference between the connection position between the longitudinal beam 13 supporting the corresponding end of the top plate 12 and the end frame 11 and the connection position between the mounting frame 15 and the end frame 11, in this embodiment of the disclosure, the side of the mounting frame 15 near the corresponding end of the top plate 12 can be spaced apart from the end frame 11, and a connecting beam 151 is provided below the longitudinal beam 13 supporting the corresponding end of the top plate 12. The two opposite ends of the connecting beam 151 in the transverse X direction are respectively connected to the mounting frame 15 and the end frame 11 to enhance the stability of the connection between the mounting frame 15 and the end frame 11.

[0097] For example, such as Figure 8 As shown, in the horizontal direction X, the top plate 12 is inclined downward from left to right. In order to avoid interference between the connection position between the longitudinal beam 13 supporting the top plate 12 on the right side and the connection position between the mounting frame 15 and the end frame 11, the right end of the mounting frame 15 can be spaced apart from the end frame 11. At the same time, a connecting beam 151 is provided at the right end of the mounting frame 15 to realize the connection between the mounting frame 15 and the end frame 11.

[0098] like Figure 1 , Figure 2 and Figure 9 As shown, in some embodiments, the on-board hydrogen supply system may include two lifting plates 14 located at opposite ends of the tank 2 in the axial direction and above the top plate 12, that is, the lifting plates 14 are located on the side of the top plate 12 away from the bottom plate.

[0099] Specifically, the mounting plate 14 can be set inside the corresponding end frame 11 to reduce the space occupied by the frame, thereby reducing the overall space occupied by the on-board hydrogen supply system and improving the aesthetics of the on-board hydrogen supply system.

[0100] The lifting plate 14 can be provided with multiple evenly arranged lifting holes 141. Lifting equipment can be connected to the lifting holes 141 to realize the rapid installation and disassembly of the on-board hydrogen supply system and the vehicle.

[0101] like Figure 9 As shown, in some embodiments, the lifting plate 14 may also be provided with a strap hole 142. By providing a strap in the strap hole 142, the on-board hydrogen supply system can be fixed to the vehicle. Since the connection between the strap and the vehicle does not require bolts or other fasteners, the hydrogen supply system can also be quickly installed and removed from the vehicle.

[0102] like Figure 1 , Figure 2 and Figure 7As shown, in some embodiments, the on-board hydrogen supply system may include an intake pipe 31 and a connecting pipe 32. The intake pipe 31 passes through the mounting bracket 15 and is fixed to the mounting base plate 152. One end of the connecting pipe 32 is connected to the intake pipe 31, and the other end extends to the bottle opening and communicates with the inside of the tank 2.

[0103] like Figure 7 As shown, in this embodiment of the present disclosure, the air intake pipe 31 can be arranged at a horizontal X-distance from the display device 5.

[0104] like Figure 6 As shown, in some embodiments, the mounting bracket 15 can be connected to an openable protective cover 154. The protective cover 154 is located on the opening side of the mounting bracket 15 and forms a protective space with the mounting bracket 15. The outer end of the air intake pipe 31 away from the connecting pipe 32 is accommodated in the protective space.

[0105] For example, in this embodiment of the present disclosure, the protective cover 154 can be movably connected to the mounting bracket 15 via a hinge. When it is necessary to fill the tank 2 with hydrogen, the protective cover 154 can be opened to connect the inlet pipe 31 to the external hydrogen supply pipe. When it is not necessary to fill the tank 2 with hydrogen, the protective cover 154 can be closed to isolate the inlet pipe 31 from the outside, thereby reducing the risk of contamination of the inlet pipe 31 by external factors.

[0106] like Figure 2 As shown, in some embodiments, the delivery pipeline may include a gas outlet pipeline 33, which is located at the axial end of the tank 2 near the bottle opening. The tank 2 can output hydrogen gas through the gas outlet pipeline 33.

[0107] It should be noted that in existing on-board hydrogen supply systems, metal hoses and compression fittings are typically used to connect to the hydrogen supply lines on the vehicle. This connection method is not convenient for loading and unloading the on-board hydrogen supply system and the hydrogen supply lines, which leads to low loading and unloading efficiency between the on-board hydrogen supply system and the hydrogen supply lines.

[0108] To solve the above technical problems, such as Figure 2 As shown, the on-board hydrogen supply system in this embodiment may include a quick-connect connector 6. The quick-connect connector 6 is hollow inside, and the inlet end of the quick-connect connector 6 is connected to the gas outlet pipe 33. The outlet end of the quick-connect connector 6 can be used to connect to the hydrogen supply pipe on the vehicle. The hydrogen supply pipe can deliver hydrogen obtained from the tank 2 to the fuel cell on the vehicle.

[0109] This embodiment of the present disclosure connects a quick-connect fitting 6 to the outlet end of the gas outlet pipe 33 to enable quick connection between the gas outlet pipe 33 and the hydrogen supply pipe. This improves the installation and disassembly speed of the on-board hydrogen supply system and the vehicle, while also enhancing the stability and sealing of the connection between the gas outlet pipe 33 and the hydrogen supply pipe, thereby improving the safety of hydrogen transportation.

[0110] In some embodiments, the quick-connect connector 6 may include a female connector 61 and a male connector 62 partially inserted into the female connector 61. The inlet end of the quick-connect connector 6 is located at the end of the female connector 61 away from the male connector 62, and the outlet end of the quick-connect connector 6 is located at the end of the male connector 62 away from the female connector 61.

[0111] For details, please refer to [link / reference]. Figures 10 to 11 As shown, Figure 11 The left end of the 62-inch head of the middle public head is from Figure 10 The right end of the middle female head 61 is embedded inside the female head 61.

[0112] In some embodiments, a sealing ring may be provided inside the female connector 61. The sealing ring is located at the end of the female connector 61 near the male connector 62 and surrounds the inner sidewall of the female connector 61. When the male connector 62 is connected to the female connector 61, the opposite sides of the sealing ring can abut against the male connector 62 and the female connector 61 respectively, thereby improving the sealing performance of the connection between the male connector 62 and the female connector 61 and reducing the risk of leakage during hydrogen transportation.

[0113] In some embodiments, a rotating protective cover may be fitted around the outer periphery of the quick-connect connector 6. The rotating protective cover is threadedly connected to the outer periphery of the male connector 62 and the outer periphery of the female connector 61. Before separating the male connector 62 and the female connector 61, the rotating protective cover needs to be rotated to unlock it.

[0114] This embodiment of the invention strengthens the stability of the connection between the male connector 62 and the female connector 61 by providing a rotating protective cover, reducing the possibility of accidental detachment of the male connector 62 and the female connector 61 due to vibration or accidental contact during use, thereby reducing the risk of hydrogen leakage and improving the safety of hydrogen transportation.

[0115] In some embodiments, a spring clip may be provided on the inner sidewall of the female connector 61, located on the side of the female connector 61 closer to the male connector 62. A groove adapted to the spring clip is provided on the outer sidewall of the male connector 62, with the groove opening facing away from the central axis of the male connector 62. The spring clip is capable of elastic deformation to detachably connect with the groove on the outer sidewall of the male connector 62.

[0116] Specifically, during the process of the male connector 62 being engaged with the female connector 61, the spring clip undergoes elastic deformation outward under the pressure of the male connector 62, that is, the spring clip undergoes elastic deformation away from the central axis of the male connector 62 under the pressure of the male connector 62. After the spring clip is engaged in the slot, the spring clip returns to its original shape and engages with the side wall of the slot, thereby achieving automatic locking and sealing between the male connector 62 and the female connector 61, reducing the risk of hydrogen leakage. At the same time, because the spring clip can undergo elastic deformation, this embodiment of the present disclosure can also control the deformation of the spring clip to quickly achieve the installation and removal of the male connector 62 and the female connector 61.

[0117] In some embodiments, control valves may be installed on the tank 2 and the delivery pipeline to control the delivery of hydrogen in the tank 2 and the delivery pipeline.

[0118] like Figure 1 As shown, the on-board hydrogen supply system may also include a controller 7 mounted on the frame. The controller 7 is located on one side of the tank 2 in the transverse X direction, and the controller 7 is located at the end of the frame near the bottle opening.

[0119] In this embodiment of the present disclosure, the controller 7 can communicate with the detection device and the control valve. The controller 7 can obtain the parameters detected by the detection device and control the opening and closing of the control valve according to the parameters.

[0120] For example, when the detection equipment detects the pressure parameter of hydrogen in tank 2 and transmits it to controller 7, controller 7 can judge the pressure parameter and control the opening and closing of the corresponding controllers on tank 2 and the delivery pipeline. If the pressure value is abnormal, controller 7 can judge the abnormal parameter and provide corresponding handling suggestions while issuing an alarm.

[0121] For example, if the controller 7 determines that the pressure of the hydrogen in the tank 2 is too high, the controller 7 can control the control valve on the tank 2 to close, thereby stopping the continued supply of hydrogen into the tank 2. At the same time, the controller 7 can transmit the acquired parameter information and the diagnostic results of abnormal parameters to the display device 5, so as to prompt the user through the display device 5, thereby improving the interactivity between the on-board hydrogen supply system and the user.

[0122] It should be noted that the movable power supply device 52 in the display device 5 can be used to supply power to the controller 7, so that the controller 7 can monitor the entire on-board hydrogen supply system in real time. In particular, by positioning the controller 7 on the side of the frame closer to the display device 5 in the longitudinal Y direction, the length of the wiring harness between the movable power supply device 52 and the controller 7 can be shortened, thereby reducing the manufacturing cost of the on-board hydrogen supply system.

[0123] like Figure 2As shown, in some embodiments, a bottle neck valve 8 can be provided at the bottle neck, and the bottle neck valve 8 is sealed to the tank body 2. The delivery pipeline can be connected to the bottle neck valve 8, so that the delivery of hydrogen in the tank body 2 and the delivery pipeline can be controlled by controlling the opening and closing of the bottle neck valve 8.

[0124] In this embodiment of the disclosure, the display device 5 can be used to display the energization status of the bottle neck valve 8.

[0125] like Figure 2 As shown, in some embodiments, a pressure reducing valve 9 can be installed on the delivery pipeline. The pressure reducing valve 9 adjusts the outlet pressure of hydrogen in the delivery pipeline by changing the throttling area to cause different pressure losses, thereby realizing the pressure reduction and pressure stabilization functions of the delivery pipeline.

[0126] In some embodiments, the detection device may include a temperature sensor, which may be disposed inside the tank 2 to detect the temperature parameters inside the tank 2.

[0127] like Figure 2 As shown, in some embodiments, the detection device may include a pressure sensor 41, which may be located on the delivery pipeline and / or at the bottle opening, for detecting the pressure on the delivery pipeline and / or inside the tank 2.

[0128] For example, pressure sensor 41 can be installed at the outlet end of pressure reducing valve 9 in the delivery pipeline to monitor the outlet pressure of hydrogen in the delivery pipeline after it has been regulated by pressure reducing valve 9, thereby facilitating the adjustment of the hydrogen pressure in the delivery pipeline.

[0129] like Figure 12 As shown, in some embodiments, the detection device may include a concentration sensor 42, which may be installed on the top of the tank 2 to detect the sealing condition of the tank 2, and can stop the delivery of hydrogen in time when a hydrogen leak is detected, and perform maintenance on the on-board hydrogen supply system.

[0130] In some embodiments, the detection device may include a mass sensor, which may be located at the bottle opening to detect the mass of hydrogen gas inside the tank 2.
