Description

Technical Field

[0001] The present application relates to the field of vehicle energy supply, and in particular to a hydrogen supply system for hydrogen energy trucks. Background Art

[0002] Hydrogen vehicles are powered by hydrogen, converting the chemical energy generated by hydrogen reactions into mechanical energy to propel the vehicle. Hydrogen vehicles offer advantages such as low greenhouse gas emissions, quick refueling times, and a long driving range, making them ideal for medium- and long-distance transportation or heavy-load transport.

[0003] As an emerging heavy-duty transport vehicle, hydrogen-powered trucks are more environmentally friendly than diesel-fueled hydrogen-powered trucks. Compared with pure electric-traction hydrogen-powered trucks, they have the advantages of short energy replenishment time and large load capacity.

[0004] In the existing technology, hydrogen trucks are generally refueled by on-site hydrogen refueling. During the hydrogen refueling process, a small amount of hydrogen leakage is inevitable, which poses a safety hazard for places such as mines. Summary of the Invention

[0005] In order to reduce the safety and hidden dangers of hydrogen energy trucks when they are not refueled, this application provides a hydrogen supply system for hydrogen energy trucks.

[0006] The hydrogen energy truck hydrogen supply system provided in this application adopts the following technical solutions:

[0007] The hydrogen supply system of a hydrogen energy truck includes a hydrogen module carrier and a lifting device. The hydrogen module carrier is used to load replacement hydrogen modules and consumed hydrogen modules; the lifting device includes a main slide rail, a gantry, a top frame and a lifting locking device; the main slide rail is used to be fixedly installed on the ground, and the gantry is slidingly mounted on two main slide rails parallel to each other. The sliding direction of the gantry is defined as longitudinal, and the gantry is provided with a longitudinal drive mechanism, and the longitudinal drive mechanism is used to drive the gantry to move longitudinally; the top frame slides The top frame is installed on the top of the gantry, the sliding direction of the top frame is defined as horizontal, and the top frame is provided with a horizontal driving mechanism, and the horizontal driving mechanism is used to drive the top frame to move horizontally; the lifting locking device is installed on the top frame, and the lifting locking device is used to grab and lift the hydrogen module; the area between the two main slide rails is used as the hydrogen exchange operation area, and when the hydrogen module carrier and the hydrogen energy truck are parked in the hydrogen exchange operation area, the front directions of the hydrogen module carrier and the hydrogen energy truck are both parked in the longitudinal direction.

[0008] By adopting the above technical solution, a hydrogen module carrier loaded with a replacement hydrogen module is parked in the hydrogen exchange operation area, which is located in the installation area of the lifting equipment. The gantry of the lifting equipment can move longitudinally, and the top frame of the lifting equipment can move laterally. When the hydrogen energy of the hydrogen energy truck needs to be replenished, the hydrogen energy truck enters the hydrogen exchange operation area and maintains the same orientation as the hydrogen module carrier. Then, the lifting locking device of the lifting equipment moves to the top of the hydrogen energy truck, and the consumed hydrogen module is lifted and removed using the lifting locking device. Then, the lifting locking device is moved to the top of the hydrogen module carrier, and the replacement hydrogen module is hoisted onto the hydrogen energy truck for assembly. In the above process, the hydrogen energy truck is replenished with hydrogen energy by directly replacing the hydrogen module, which is less likely to cause hydrogen leakage and is conducive to ensuring safe operation. Moreover, in some places where it is not possible to build a hydrogen station nearby due to safety considerations, replenishing hydrogen energy by replacing the hydrogen module can reduce the distance that the hydrogen energy truck needs to travel to refuel, which is conducive to saving time and improving efficiency.

[0009] Optionally, the main slide rail includes a longitudinal steel rail and a support truss, the support truss includes a steel beam and a plurality of support legs, the steel beam is arranged longitudinally, and the longitudinal steel rail is fixed to the top of the steel beam longitudinally; multiple groups of support legs are arranged at intervals along the longitudinal direction, and the support legs include vertical support rods and oblique support rods, the vertical support rod is located directly below the steel beam, the upper end of the oblique support rod is connected to the upper end of the vertical support rod, and the lower end of the oblique support rod is laterally offset from the vertical support rod.

[0010] By adopting this technical solution, the longitudinal rails are mounted on the steel beams supporting the trusses, maintaining a sufficient height difference between the rails and the ground, which helps reduce dust contamination of the rail surface. The vertical support rods and the diagonal support rods together with the ground form a triangular area, which is highly stable and helps to ensure the structural stability of the support legs.

[0011] Optionally, limit blocks are respectively provided at both ends of the steel beam, and the limit blocks are used to limit the longitudinal movement range of the gantry; the longitudinal distribution range of multiple groups of support legs is located between the two end surfaces of the steel beam; the vertical support rod of the support leg near the end of the steel beam is provided with a diagonal support rod, one end of the diagonal support rod is connected to the corresponding vertical support rod, and the other end of the diagonal support rod is connected to the end of the steel beam.

[0012] By adopting the above technical solution, the limit block can limit the moving range of the gantry. When the gantry collides with the limit block, the end position of the supporting truss is subjected to a large impact force. By setting the diagonal brace rod, the structural stability of the end of the supporting truss can be improved, so that the supporting truss is not easily deformed due to the collision of the gantry.

[0013] Optionally, the body of the hydrogen module carrier is provided with a plurality of quick-change installation mechanisms, which are used to position replacement hydrogen modules or consumed hydrogen modules, and the plurality of quick-change installation mechanisms are arranged equidistantly along the length direction of the body of the hydrogen module carrier.

[0014] By adopting the above technical solution, the hydrogen module is installed in the load-bearing area of the body of the hydrogen module carrier by installing a quick-change mechanism, so that the position of the hydrogen module remains stable. When the hydrogen module carrier transports the hydrogen module, the hydrogen module is not easily damaged by vehicle bumps.

[0015] Optionally, the load-bearing area of the body of the hydrogen module carrier is divided into multiple unit load-bearing areas, each of the unit load-bearing areas corresponds to one of the installation quick-change mechanisms, the number of the unit load-bearing areas is one more than the number of the hydrogen modules, and the hydrogen module carrier is provided with a hydrogen module replacement part, and the outer contour shape of the hydrogen module replacement part is the same as that of the hydrogen module.

[0016] By adopting the above technical solution, the unit carrying areas on the hydrogen module carrier are set in a one-to-one correspondence with the installation quick-change mechanisms. The number of unit carrying areas is one more than the number of hydrogen modules. When replacing the hydrogen module of the hydrogen energy truck, the consumed hydrogen module can be directly hoisted to the vacant unit carrying area using hoisting equipment. Subsequently, the hoisting equipment will hoist the replacement hydrogen module onto the hydrogen energy truck. In the above process, the hoisting equipment does not need to place the consumed hydrogen module outside the hydrogen energy truck and the hydrogen module carrier, nor does it need to perform additional hoisting operations to the consumed hydrogen energy module onto the hydrogen module carrier, which is conducive to improving the overall working efficiency of the hydrogen energy truck hydrogen supply system.

[0017] Optionally, a hydrogen module placement platform is provided on the long side of the hydrogen module carrier, and the hydrogen module placement platform includes a platform, a limit plate, a limit bolt and a hinge seat. The platform is hinged to the body of the hydrogen module carrier, and the hinge seat is hinged to the body of the hydrogen module carrier. The hinge seat is lower than the limit plate and connected to one side of the hydrogen module carrier; the limit plate is provided with a first through hole, the platform is provided with a second through hole, and the hinge seat is provided with a threaded hole adapted to the limit bolt, and the limit bolt passes through the first through hole and the second through hole in sequence and is threadedly connected to the threaded hole. The platform is used to support the hydrogen module, and the limit plate is used to prevent the hydrogen module from leaving the platform.

[0018] By adopting the above technical solution, the limit bolts pass through the limit plate and the table in sequence and then connect to the hinge seat, so that the limit bolts, the limit plate, the table plate, and the side wall of the hydrogen module carrier together form two triangular areas, which maintains the stability of the placement platform structure and allows the hydrogen module placement platform to be used for placing hydrogen modules. In this way, when replacing the hydrogen module, the consumed hydrogen module can be hoisted onto the hydrogen module placement platform first, without having to place the consumed hydrogen module on the ground, which helps to reduce the possibility of the hydrogen module being contaminated and being knocked by foreign objects. In addition, when the consumed hydrogen module is placed on the placement platform, the first consumed hydrogen module replaced does not occupy space on the hydrogen module carrier. When the first replacement hydrogen module is removed, the hydrogen module carrier frees up space, allowing the subsequent replaced consumed hydrogen module to be directly placed on the hydrogen module carrier, which is more convenient. The limit bolts are threadedly connected to the hinge seat. When the hydrogen module carrier is transporting, the bolts can be withdrawn from the first through hole and the second through hole, allowing the table plate and the limit plate to be unfolded and drooped, thereby reducing the space occupied by the placement platform.

[0019] Optionally, an auxiliary positioning device is also included, which includes an infrared transmitter and an infrared receiver. The infrared transmitter is used to be installed on the side wall of the hydrogen module, and the infrared receiver is used to be installed on the long side of the body of the hydrogen energy truck or carrier. When the hydrogen module corresponding to the auxiliary positioning device is installed in place, the infrared transmitter and the infrared receiver are aligned up and down.

[0020] By adopting this technical solution, before the lifting equipment installs the hydrogen module on the hydrogen energy truck or hydrogen module carrier, the infrared transmitter is first installed on the side wall of the hydrogen module, and the infrared receiver is installed on the hydrogen module carrier. The lifting equipment then drives the hydrogen module to move. During the movement of the hydrogen module, the infrared receiver receives the infrared transmitter signal to help determine the horizontal alignment of the hydrogen module, which helps improve the installation efficiency of the hydrogen module.

[0021] Optionally, the light-emitting side of the infrared transmitter is a point-shaped structure, the receiving side of the infrared receiver is an elongated structure, and the long side of the receiving side of the infrared receiver is parallel to the side wall of the corresponding hydrogen module; the auxiliary positioning device includes a first auxiliary positioning device and a second auxiliary positioning device, and the first auxiliary positioning device and the second auxiliary positioning device correspond to two adjacent sides of the hydrogen module respectively.

[0022] By adopting the above technical solution, the first auxiliary positioning device and the second auxiliary positioning device can be used to determine the alignment of the hydrogen module along two mutually perpendicular horizontal directions, so that the position of the hydrogen module can be further accurately determined, which is conducive to further improving the installation efficiency of the hydrogen module.

[0023] Optionally, the infrared transmitter is provided with a first magnetic seat, and the infrared receiver is provided with a second magnetic seat. When the first magnetic seat is installed, it absorbs the side wall of the hydrogen module by magnetic attraction, and when the second magnetic seat is installed, it absorbs the body of the hydrogen energy truck or the body of the hydrogen module carrier by magnetic attraction.

[0024] By adopting the above technical solution, the infrared transmitter is installed on the side wall of the hydrogen module through the first magnetic seat, and the infrared receiver is installed on the body of the hydrogen energy truck or hydrogen module carrier through the second magnetic seat, which is more convenient.

[0025] Optionally, the lifting and locking device includes a lifting frame and a lifting drive mechanism, the lifting drive mechanism is installed on the top frame, and the lifting frame is installed below the top frame through the lifting drive mechanism. The lifting frame is provided with a plurality of positioning locking mechanisms, and the positioning locking mechanisms include claws and telescopic drive members, the claws are installed on the lifting frame through the telescopic drive member, and the claws are used to hook the lifting structure of the hydrogen module.

[0026] By adopting the above technical solution, when the lifting locking device is used, the telescopic driving member drives the L-shaped member to move, so that the L-shaped member hooks the lifting structure of the hydrogen module, so that the lifting locking device can lift the hydrogen module upward.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The hydrogen supply system refuels hydrogen trucks by directly replacing hydrogen modules, making hydrogen leaks less likely and ensuring safe operations. For applications where building a nearby hydrogen station is not feasible due to safety concerns, replacing hydrogen modules can reduce the distance hydrogen trucks need to travel to refuel, saving time and improving efficiency.

[0029] 2. When placing the consumed hydrogen module on the placement table, the first consumed hydrogen module replaced does not need to occupy space on the hydrogen module carrier. When the first replacement hydrogen module leaves, there is free space on the hydrogen module carrier, so that the subsequent replaced consumed hydrogen modules can be directly placed on the hydrogen module carrier, which is more convenient.

The consumed hydrogen module 3 can be lifted and transported to the vacant position on the hydrogen module carrier 1 using the lifting equipment 2. After all the replacement hydrogen modules 3 loaded on the hydrogen module carrier 1 have been replaced with consumed hydrogen modules 3, the consumed hydrogen modules 3 loaded on the hydrogen module carrier 1 are then uniformly refueled.

[0045] Reference Figure 2The main slide rail 21 includes a longitudinal steel rail 211 and a support truss 212. The support truss 212 includes a steel beam 2120 and a plurality of support legs 2121. The steel beam 2120 is arranged longitudinally, and the longitudinal steel rail 211 is fixed to the top of the steel beam 2120 longitudinally; the plurality of support legs 2121 are arranged equidistantly along the longitudinal direction, and the support legs 2121 include a vertical support rod 2122 and an oblique support rod 2123.

[0047] Reference Figure 3 Two longitudinal drive mechanisms 25 are provided, and the two longitudinal drive mechanisms 25 correspond to the two longitudinal rails 211 respectively. The longitudinal drive mechanism 25 includes a first motor 251, a first driving roller 252, and a first driven roller 253. The first motor 251, the first driving roller 252, and the first driven roller 253 are all mounted on the gantry 22. The first driving roller 252 and the first driven roller 253 are respectively in rolling connection with the corresponding longitudinal rails 211. The first motor 251 is used to drive the first driving roller 252 to move along the longitudinal rails 211.

[0048] Reference Figure 3 and Figure 4Two transverse rails 231 are provided on the top of the gantry 22, and two transverse drive mechanisms 26 are provided. The two transverse mechanisms correspond to the two transverse rails 231 respectively. The transverse drive mechanism 26 includes a second motor 261, a second driving roller 262 and a second driven roller 263. The second motor 261, the second driving roller 262 and the second driven roller 263 are all installed on the top frame 23. The second driving roller 262 and the second driven roller 263 are respectively connected to the corresponding transverse rails 231 in a rolling manner. The second motor 261 is used to drive the second driving roller 262 to move along the transverse rails 231.

[0049] Reference Figure 4 The lifting locking device 24 includes a lifting frame 241 and a lifting drive mechanism 243. The lifting drive mechanism 243 is installed on the top frame 23. The lifting drive mechanism 243 includes a double-roller winch 2430, four fixed pulleys 244 and four movable pulleys 245. The double-roller winch 2430 is installed in the middle area of the top frame 23. The double-roller winch 2430 has two drums 2431, each drum 2431 is provided with two steel ropes 2432, and the four fixed pulleys 244 are respectively installed at the four corners of the top frame 23, and the four fixed pulleys 244 correspond to the four steel ropes 2432 respectively; the four movable pulleys 245 are respectively installed at the four corners of the lifting frame 241, and the four movable pulleys 245 correspond to the four steel ropes 2432 respectively. The steel ropes 2432 of the winch are connected to the lifting frame 241 after passing through the corresponding fixed pulleys 244 and movable pulleys 245 in turn. The hanging frame 241 is hung below the top frame 23 through the lifting drive mechanism 243 .

[0050] The hoisting frame 241 is equipped with multiple sets of positioning and locking mechanisms 246 and multiple sets of guide posts 247. Each set of positioning and locking mechanisms 246 has two positioning and locking mechanisms 246, and the two positioning and locking mechanisms 246 in the same set are arranged opposite each other. The positioning and locking mechanisms 246 include claws 2461 and a telescopic drive member 2462. The telescopic drive member 2462 is a cylinder. The claws 2461 are mounted to the hoisting frame 241 through the telescopic drive member 2462. The claws 2461 are used to hook onto the hoisting structure of the hydrogen module 3. When the two opposing positioning and locking mechanisms 246 simultaneously hook onto the top of the hydrogen module 3, the position of the hydrogen module 3 is locked. Each group of guide columns 247 is provided with two, and the two guide columns 247 in the same group are arranged opposite to each other. The lower end surface of the guide column 247 is provided with an inclined guide surface 2471. The inclined guide surfaces 2471 of the two guide columns 247 in the same group are arranged opposite to each other or away from each other. When the lifting frame 241 moves downward, the inclined guide surface 2471 can form a guiding effect on the main frame of the hydrogen module 3, so that the light module and the lifting frame 241 are aligned up and down.

[0051] Reference Figure 5 and Figure 6The body of the hydrogen module carrier 1 is provided with a plurality of quick-change mounting mechanisms 4, which are used to position a replacement hydrogen module 3 or a consumed hydrogen module 3. The plurality of quick-change mounting mechanisms 4 are arranged equidistantly along the length of the body of the hydrogen module carrier 1. The quick-change mounting mechanisms 4 include a connecting seat 41 and eight clamping mechanisms 42. The connecting seat 41 is a welded frame structure and is used to connect to the body of the hydrogen energy truck 7. The clamping mechanisms 42 are mounted on the connecting seat 41. The eight clamping mechanisms 42 surround the center of the connecting seat 41. The clamping mechanisms 42 include a mounting post 421 and a clamping assembly 422. The clamping assembly 422 includes a clamping block 4221 and a telescopic cylinder 4222. The telescopic cylinder 4222 is used to drive the clamping block 4221 to telescopically move in a direction toward or away from the center of the connecting seat 41. The mounting post 421 has a guide surface 4211, and the guide surface 4211 is tilted away from the center of the connecting seat 41.

[0052] When the hydrogen module 3 is hoisted onto the hydrogen module carrier 1, as the hydrogen module 3 moves downward, the guide surface 4211 of the mounting column 421 abuts against the frame bar of the main frame, so that the main frame and the mounting quick-change mechanism 4 are aligned up and down. At this time, the clamping block 4221 is in a state of retreating to avoid the main frame of the hydrogen module 3; when the hydrogen module 3 is lowered into place, the telescopic cylinder 4222 drives the clamping block 4221 forward, so that the clamping block 4221 clamps the frame bar at the bottom of the main frame, so that the vertical position of the hydrogen module 3 is restricted, so that the light module is not easily affected by the bumps of the hydrogen module carrier 1 during driving.

[0053] The hoisting device 2 is equipped with an air pump, which is used to provide an air source to the hoisting locking device 24 and the cylinder for installing the quick-change mechanism 4.

[0054] The load-bearing area of the body of the hydrogen module carrier 1 is divided into a plurality of unit load-bearing areas. The number of the unit load-bearing areas is the same as the number of the hydrogen modules 3 , and each unit load-bearing area corresponds to an installation quick-change mechanism 4 .

[0055] The implementation principle of the hydrogen supply system of the hydrogen energy truck of the embodiment of the present application is as follows: the hydrogen module carrier 1 loaded with the replacement hydrogen module 3 is parked in the hydrogen exchange operation area. When the hydrogen energy truck 7 needs to replenish hydrogen energy, the hydrogen energy truck 7 enters the hydrogen exchange operation area and maintains the same direction as the hydrogen module carrier 1. Then, the lifting locking device 24 of the lifting equipment 2 is moved to the top of the hydrogen energy truck 7, and the consumed hydrogen module 3 is lifted and removed by using the lifting locking device 24. Then, the lifting locking device 24 is moved to the top of the hydrogen module carrier 1, and the replacement hydrogen module 3 is lifted onto the hydrogen energy truck 7 for assembly. After all the replacement hydrogen modules 3 on the hydrogen module carrier 1 are replaced with consumed hydrogen modules 3, the hydrogen module carrier 1 transports all the consumed hydrogen modules 3 to the hydrogen station for hydrogen refueling.

[0056] By directly replacing the hydrogen module 3 to refill the hydrogen truck 7, hydrogen leaks are less likely to occur, ensuring safe operation. Furthermore, in situations where it's impossible to build a nearby hydrogen refueling station for safety reasons, replacing the hydrogen module 3 can reduce the distance the hydrogen truck 7 needs to travel to refuel, saving time and improving efficiency.

[0057] Example 2

[0058] Reference Figure 7 and Figure 8 , the difference between this embodiment and embodiment 1 is that: a hydrogen module 3 placement platform is provided on the long side of the hydrogen module carrier 1, and the hydrogen module 3 placement platform includes a platform 51, a limiting plate 52, a limiting bolt 53 and a hinge seat 54. The platform 51 is hinged to the body of the hydrogen module carrier 1, and the hinge seat 54 is hinged to the body of the hydrogen module carrier 1. The hinge seat 54 is lower than the side of the limiting plate 52 connected to the hydrogen module carrier 1; the limiting plate 52 is provided with a first through hole 511, the platform 51 is provided with a second through hole 521, and the hinge seat 54 is provided with a limiting bolt 53. The threaded hole 541 is adapted for the bolt 53, and the limiting bolt 53 passes through the first through hole 511 and the second through hole 521 in sequence and is threadedly connected to the threaded hole 541. The table 51 is used to support the hydrogen module 3, and the limiting plate 52 is used to prevent the hydrogen module 3 from leaving the table 51; there are two limiting bolts 53, and the two limiting bolts 53 are respectively located on two opposite sides of the table 51. The area of the table 51 between the two limiting bolts 53 is used as the placement area of the hydrogen module 3. The limiting bolt 53 can play a limiting role on the hydrogen module 3 on the table 51.

[0059] When replacing the hydrogen module 3, the consumed hydrogen module 3 can be first hoisted onto the placement table for the hydrogen module 3. A unit carrying area on the hydrogen module carrier 1 is left vacant; when the subsequent hydrogen energy truck 7 needs to replace the light module, the hoisting equipment 2 can directly hoist the consumed hydrogen module 3 onto the vacant unit carrying area on the hydrogen module carrier 1. When all the replacement hydrogen modules 3 on the hydrogen module carrier 1 are replaced with consumed hydrogen modules 3, the hydrogen modules 3 on the placement table are hoisted onto the vacant unit carrying area on the hydrogen module carrier 1. When the hydrogen module carrier 1 is performing transportation operations, the limit bolts 53 can be removed to unfold the table 51 and the limit plate 52 to reduce the space occupied by the placement table.

[0060] The limiting bolt 53 is sleeved with a wedge washer 55, which is located between the bolt cap of the limiting bolt 53 and the limiting plate 52. The wedge washer 55 occupies the gap between the bolt cap of the limiting bolt 53 and the limiting plate 52, making the connection between the limiting bolt 53 and the limiting plate 52 stable.

[0061] Reference Figure 9The hydrogen supply system for hydrogen energy trucks in this embodiment also includes an auxiliary positioning device 6, which includes an infrared emitter 61 and an infrared receiver 62. The infrared emitter 61 is intended to be mounted on the side wall of the hydrogen module 3, and the infrared receiver 62 is intended to be mounted on the long side of the body of the hydrogen energy truck 7 or the carrier vehicle. The emitting side of the infrared emitter 61 is a dot-shaped structure, and the receiving side of the infrared receiver 62 is an elongated structure, with the long side of the receiving side of the infrared receiver 62 parallel to the side wall of the corresponding hydrogen module 3. The infrared emitter 61 is provided with a first magnetic seat 63, which is magnetically attached to the side wall of the hydrogen module 3 during installation. The infrared receiver 62 is provided with a second magnetic seat 64, which is magnetically attached to the body of the hydrogen energy truck 7 or the body of the hydrogen module carrier 1 during installation.

[0062] The auxiliary positioning device 6 is divided into a first auxiliary positioning device 6 and a second auxiliary positioning device 6 according to different action positions on the hydrogen module 3 . The first auxiliary positioning device 6 and the second auxiliary positioning device 6 correspond to two adjacent sides of the hydrogen module 3 respectively.

[0063] Before the hoisting equipment 2 installs the hydrogen module 3 onto the hydrogen energy truck 7 or hydrogen module carrier 1, it first installs the infrared emitter 61 onto the side wall of the hydrogen module 3 and the infrared receiver 62 onto the hydrogen module carrier 1. The hoisting equipment 2 then moves the hydrogen module 3. During this movement, the first and second auxiliary positioning devices 6 are used to determine the alignment of the hydrogen module 3 along two mutually perpendicular horizontal directions. When the hydrogen module 3 corresponding to the auxiliary positioning device 6 is in place, the infrared emitter and the infrared receiver 62 are aligned vertically. Installing the hydrogen module 3 using the auxiliary positioning devices 6 can improve the installation efficiency of the hydrogen module 3.

[0064] It should be noted that the infrared device of the auxiliary positioning apparatus 6 in this embodiment can be replaced by a laser, and the infrared receiver 62 can be replaced by a laser detector.

[0065] Example 3

[0066] The difference between this embodiment and embodiment 1 is that: in this embodiment, the number of unit carrying areas is one more than the number of hydrogen modules 3, and the hydrogen module carrier 1 is provided with a hydrogen module 3 replacement part, and the outer contour shape of the hydrogen module 3 replacement part is the same as that of the hydrogen module 3.

[0067] The unit carrying areas on the hydrogen module carrier 1 are arranged in a one-to-one correspondence with the installation quick-change mechanisms 4. The number of unit carrying areas is one more than the number of hydrogen modules 3. When replacing the hydrogen module 3 of the hydrogen energy truck 7, the hoisting equipment 2 can be used to directly hoist the consumed hydrogen module 3 into the vacant unit carrying area. Subsequently, the hoisting equipment 2 hoists the replacement hydrogen module 3 onto the hydrogen energy truck 7. In the above process, the hoisting equipment 2 does not need to place the consumed hydrogen module 3 anywhere other than the hydrogen energy truck 7 and the hydrogen module carrier 1, nor does it need to perform additional hoisting operations to hoist the consumed hydrogen energy module onto the hydrogen module carrier 1, which is beneficial to improving the overall working efficiency of the hydrogen energy truck hydrogen supply system.

[0068] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
