Description

Technical Field

[0001] This invention relates to the field of hydrogen swapping robot technology, specifically a mobile hydrogen swapping robot for heavy-duty hydrogen fuel cell trucks. Background Technology

[0002] The prospects for hydrogen-powered heavy-duty trucks are broad, with enormous market potential. Firstly, with their advantages of zero emissions, high energy density, and long driving range, hydrogen-powered heavy-duty trucks have become a crucial technological path for reducing carbon emissions and promoting green transportation. Currently, to reduce hydrogen costs, the hydrogen refueling process is modeled after battery swapping systems for heavy-duty trucks, featuring a detachable structure. The upper frame of the hydrogen tank module can be lifted by a hydrogen swapping robot, while the vehicle-mounted base with a locking device locks the lower frame of the module. The base is fixed to the vehicle's main beam, allowing the empty hydrogen tank module to be lifted and unloaded, replaced with a full one, and then refilled with hydrogen. Under this hydrogen swapping model, storage and transportation costs are reduced to one-third of those for traditional pure hydrogen for vehicles. This breaks the monolithic nature of the hydrogen supply system, avoids energy loss during repeated hydrogen refueling, and compresses the single hydrogen swapping process to 3-5 minutes. A single hydrogen swapping system can swap up to 180 vehicles in 24 hours, with a refueling capacity equivalent to a 9-ton super-large hydrogen refueling station, significantly improving the refueling capacity of hydrogen-powered vehicles.

[0003] Currently, hydrogen fuel cell heavy trucks are used for long-term outdoor transportation services. During rainy or snowy weather, a lot of rain and snow tend to accumulate on the top of the hydrogen tank module. When empty hydrogen tank modules are hoisted for replacement, the rain and snow can easily scatter to various places. This can cause the electronic components in the hydrogen filling equipment to come into contact with the rain and snow during the hydrogen filling process, which can easily lead to short circuits and damage to the electronic components in the hydrogen filling equipment, thus affecting the replacement of the hydrogen tank module. Summary of the Invention

[0004] This invention provides a mobile hydrogen swapping robot for heavy-duty hydrogen fuel cell trucks. During the hydrogen tank module replacement process, a first blowing nozzle fixed to a mounting plate can blow rain and snow adhering to the top of the hydrogen tank module to both sides in rainy or snowy weather. This reduces the risk of short circuits and damage caused by rain and snow contacting the internal electronic components of the replaced hydrogen tank module during the hydrogen filling process. This solves the problem mentioned in the background art where, during the replacement of empty hydrogen tank modules, rain and snow easily scatter to various places, causing contact between the electronic components in the hydrogen filling equipment and the rain and snow, leading to short circuits and damage, thus affecting the replacement of the hydrogen tank module.

[0016] The present invention has the following beneficial effects:

[0017] 1. In this hydrogen fuel cell heavy-duty truck mobile hydrogen swapping robot, the horizontal movement position of the mobile truss can be adjusted by the set slide rail, mobile platform, and first mobile wheel, which facilitates the adjustment of its movement direction when the hydrogen tank module is hoisted. The second mobile wheel of the C-shaped seat can move on the mobile truss, which can realize the purpose of adjusting the working position of the C-shaped seat and the hoisting component. The servo hydraulic cylinder in the hoisting component can adjust the vertical movement position of the mounting plate and the positioning wedge block fixed on the mounting plate, so that when the positioning wedge block moves down, it can be inserted into the hoisting bracket fixed on the hydrogen tank module for positioning. When the rotary electric cylinder drives the clamping block to rotate, it can be locked into the bottom of the hoisting bracket, which facilitates the precise locking of the hoisting bracket and the hoisting component and improves the stability of the hydrogen tank module hoisting. The first blowing nozzle fixed on the mounting plate can blow the rain and snow attached to the top of the hydrogen tank module to both sides in rainy and snowy weather.

[0018] The rack that slides on the mounting plate allows the rack to contact the first wave plate on the C-shaped seat when the hoisting component moves vertically. This causes the rack to drive the gear to rotate, which in turn causes the two first rotating rods to drive the second air nozzle to rotate repeatedly. This effectively removes rain and snow from the top of the hydrogen tank module, reducing cleaning dead zones.

[0019] 2. In this mobile hydrogen swapping robot for heavy-duty hydrogen fuel cell trucks, a sponge wiping block can wipe and absorb rain and snow adhering to the sides of the hoisted hydrogen tank module, thereby reducing moisture on the hydrogen tank module. When the triangular contact head comes into contact with the hoisted hydrogen tank module, it can achieve the purpose of linkage between the first contact rod, the mounting bracket, the rocker plate, and the sliding bracket. The sponge wiping block extends out of the water collection tank and automatically abuts against the side of the hydrogen tank module. When the hydrogen tank module moves vertically, it can wipe the rain and snow clean. This reduces the risk of rain and snow coming into contact with the internal electronic equipment of the replaced hydrogen tank module during the hydrogen filling process, which could cause short circuits and damage, affecting the filling operation of the hydrogen tank module and thus improving the hydrogen filling efficiency.

[0020] The water-squeezing plate on the second rotating rod inside the water collection tank deflects when the sponge wiping block retracts into the water collection tank, automatically squeezing out the water absorbed inside the sponge wiping block so that the water can fall to the bottom of the water collection tank, thereby reducing the moisture inside the sponge wiping block and making it easier for the sponge wiping block to have a better absorption effect when it works next time.

[0021] 3. In this mobile hydrogen exchange robot for heavy-duty hydrogen fuel cell trucks, water can be discharged and reused through a drain outlet at one end of the water collection tank. Two sealing plates on the drain outlet, when fitted together, prevent water from spilling from the collection tank during hoisting. A recycling tank at one end of the mobile truss allows for the recycling of water from the collection tank, reducing water waste and improving environmental protection and energy efficiency. The drain outlet allows insertion into the recycling tank's inlet. Simultaneously, the conical contact plate of the inlet contacts the second contact frame on the sealing plate, causing the sealing plate to separate and allowing water from the collection tank to flow into the recycling tank. A filter plate filters the water, improving the quality of water recycling. A strip rod moves the second wave plate when the triangular contact head resets, causing the conical contact frame and contact column to work together, enabling the brush plate to reciprocate and clean the filter plate surface, thereby increasing the water flow rate and filtration effect in the drain outlet.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1, please refer to Figures 1 to 10 A mobile hydrogen swapping robot for heavy-duty hydrogen fuel cell trucks includes a mobile truss 1, with mobile platforms 2 fixed at both ends of the mobile truss 1. First mobile wheels 3 are installed below the mobile platforms 2. A slide rail 4 is provided below the mobile truss 1, with the first mobile wheels 3 located on the slide rail 4. A U-shaped seat 5 is provided on the mobile truss 1, with second mobile wheels 6 installed on both sides of the U-shaped seat 5. Two strip grooves 7 are opened on the mobile truss 1, with the second mobile wheels 6 located in the strip grooves 7.

[0035] Below the C-shaped base 5 is a hydrogen tank module 8, and a lifting bracket 9 is fixed on the hydrogen tank module 8. The C-shaped base 5 is provided with a lifting assembly for lifting the lifting bracket 9, and the lifting assembly is provided with several equidistantly distributed first air blowing nozzles 10.

[0036] The hoisting assembly includes a servo hydraulic cylinder 81, which is fixed on the C-shaped seat 5. The piston rod end of the servo hydraulic cylinder 81 is fixed with a mounting plate 82. Positioning wedge blocks 83 are fixed around the mounting plate 82. Several rotary electric cylinders 84 are fixed on the mounting plate 82. A locking block 85 is fixed on the rotating end of the rotary electric cylinder 84. Several first air blowing nozzles 10 are installed on the mounting plate 82.

[0037] Two first rotating rods 11 are rotatably connected to both sides of the mounting plate 82. Several second air blowing nozzles 12 are fixed on the first rotating rods 11. The second air blowing nozzles 12 are located on one side of the first air blowing nozzles 10. A gear 13 is fixed to one end of the first rotating rod 11. A rack 14 is meshed on the gear 13. The rack 14 is slidably connected to the mounting plate 82. A first spring 15 is connected between the rack 14 and the mounting plate 82. A first wave plate 16 is provided on both sides of the C-shaped seat 5. One end of the rack 14 abuts against the first wave plate 16.

[0038] The hydrogen fuel cell heavy-duty truck is equipped with a hydrogen exchange base, which engages with the bottom of the hydrogen tank module 8. The base also features a hydrogen connector, which is electrically connected to the bottom of the hydrogen tank module 8 using a quick-plug connection structure. (See reference...) Figures 1-5 The first moving wheel 3, installed below the moving platform 2, rolls on the slide rail 4, thereby adjusting the position of the moving truss 1 so that the moving truss 1 is aligned with the hydrogen tank module 8 to be replaced. Then, the second moving wheel 6, installed on the C-shaped seat 5, rolls on the two slots 7 on the moving truss 1, thereby adjusting the position of the C-shaped seat 5 and the lifting assembly on it, so that the lifting assembly is positioned directly above the hydrogen tank module 8 of the heavy truck. During lifting, the servo hydraulic cylinder 81 of the lifting assembly moves the mounting plate 82 downwards, causing the positioning wedges 83 fixed around the mounting plate 82 to insert into the hydrogen tank module 8. Positioning the hydrogen tank module 8 on the lifting bracket 9 prevents it from swaying during hoisting. The rotating end of the rotary electric cylinder 84 drives the locking block 85 to rotate, thus positioning the locking block 85 on the lifting bracket 9. At the same time, the hydrogen replacement base releases the locking state of the hydrogen tank module 8. When the piston rod of the servo hydraulic cylinder 81 retracts, the hydrogen tank module 8 on the heavy truck can be hoisted. During the hoisting process, the hydrogen connector separates from the quick-release connection structure at the bottom of the hydrogen tank module 8, and the hydrogen tank module 8 gradually moves into the C-shaped seat 5. The first moving wheel 3 and the second moving wheel 6 are both driven by motors.

[0039] When rain or snow appears on the top of the hydrogen tank module 8, the first air nozzle 10 fixed on the mounting plate 82 is activated, causing the gas blown out by the first air nozzle 10 to blow the rain or snow away to both sides of the hydrogen tank module 8. Figures 4-5Simultaneously, when the mounting plate 82 moves upward, it can drive the two racks 14 to move upward synchronously, causing one end of each rack 14 to abut against the first wave plate 16 set on the shaped seat 5. The first spring 15 continuously stores and releases its elasticity, causing the racks 14 to rotate when they move back and forth, thereby driving the gear 13 fixed at one end of the first rotating rod 11 to rotate. This causes the first rotating rod 11 to drive the second air nozzle 12 to swing. The second air nozzle 12 is initially set at an angle, allowing rain and snow to be discharged to both sides of the hydrogen tank module 8, which can further improve the rain and snow removal effect on the top of the hydrogen tank module 8 and reduce the dead corners of the removal.

[0040] Example 2 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1 to 10 A water collection tank 17 is provided on the C-shaped base 5, and a sponge wiping block 18 is provided in the water collection tank 17. A sliding bracket 19 is fixed on the sponge wiping block 18, and the sliding bracket 19 is elastically connected to the C-shaped base 5 through a second spring 191.

[0041] A triangular abutment head 20 is provided below the water collection tank 17. A first abutment rod 21 is fixed on the triangular abutment head 20. The first abutment rod 21 is slidably connected to the incline seat 5. The triangular abutment head 20 is elastically connected to the incline seat 5 through a third spring 22.

[0042] A mounting bracket 23 is fixed on the C-shaped base 5. A rocker plate 24 is rotatably connected to the mounting bracket 23. The rocker plate 24 is elastically connected to the mounting bracket 23 through a first torsion spring 241. The two ends of the rocker plate 24 abut against the first abutting rod 21 and the sliding bracket 19, respectively.

[0043] Two second rotating rods 25 are rotatably connected to the water collection tank 17. A water squeezing plate 26 is fixed on the second rotating rod 25. A second torsion spring 27 is connected between the second rotating rod 25 and the water collection tank 17.

[0044] The two sides of the C-shaped base 5 are slidably connected with second abutment rods 28. The second abutment rods 28 are elastically connected to the C-shaped base 5 through a fourth spring 29. The C-shaped base 5 has a cavity 30. A first abutment frame 31 and a trapezoidal abutment block 32 are respectively arranged in the cavity 30. The first abutment frame 31 is elastically connected to the C-shaped base 5 through a fifth spring 33, and the first abutment frame 31 abuts against the second abutment rod 28. The trapezoidal abutment block 32 is fixed on the first abutment rod 21.

[0045] Because the mounting bracket 9 fixed to the hydrogen tank module 8 prevents rain and snow from being discharged from both ends during the snow removal process, it needs to be discharged from both sides of the hydrogen tank module 8. This causes some rain and snow to adhere to the surface of both sides of the hydrogen tank module 8, requiring wiping and adsorption. (Refer to...) Figures 3-10When the hydrogen tank module 8 is hoisted and moved upwards, the triangular contact head 20 can abut against the hydrogen tank module 8, causing the triangular contact head 20 to drive the first contact rod 21 to move horizontally on the C-shaped seat 5. The third spring 22 stores force, and the first contact rod 21 can abut against one end of the rocker 24 during the movement, causing the rocker 24 to rotate on the mounting bracket 23. The first torsion spring 241 stores force, and the rocker 24 can abut against the sliding bracket 19 during the rotation, causing the sliding bracket 19 to slide on the C-shaped seat 5. Spring 191 stores energy and pushes the sponge wiping block 18 out of the water collection tank 17 so that it can press against the surface of the hydrogen tank module 8. The sponge wiping block 18 can absorb rainwater and some melted snow water, and wipe the unmelted snow downwards to remove it from the surface of the hydrogen tank module 8, thereby reducing the rain and snow attached to the hydrogen tank module 8. This minimizes the contact between rain and snow and the internal electronic equipment of the replaced hydrogen tank module 8 during the hydrogen filling process, so as to avoid short circuits and damage, which would affect the filling operation of the hydrogen tank module 8 and thus improve the hydrogen filling efficiency.

[0046] When the hydrogen tank module 8 moves to the position directly above the hydrogen filling equipment, refer to Figures 4-10 The hydrogen tank module 8 is lowered into the hydrogen filling equipment using a hoisting assembly. It gradually detaches from the I-shaped base 5 until the triangular contact head 20 releases its contact with the hydrogen tank module 8, allowing it to reset. Simultaneously, the first contact rod 21, mounting bracket 23, rocker plate 24, and sliding bracket 19 work together to retract the sponge wiping block 18 into the water collection tank 17. At the same time, the first contact frame 31 drives the trapezoidal contact block 32 to move horizontally, achieving contact between the trapezoidal contact block 32 and the first contact frame 31. This causes the first contact frame 31 to move vertically within the cavity 30 on the I-shaped base 5. In a straight sliding motion, the fifth spring 33 stores energy, allowing the first contact frame 31 to simultaneously contact the two second contact rods 28, pushing the second contact rods 28 to slide on the U-shaped seat 5. The fourth spring 29 stores energy, causing the second contact rods 28 to push the water-squeezing plates 26 fixed on the two second rotating rods 25 to deflect. The second torsion spring 27 stores energy, and the deflected water-squeezing plates 26 can squeeze the sponge wiping block 18 in the water collection tank 17, causing rainwater to fall into the water collection tank 17, thus reducing the moisture in the sponge wiping block 18 and making it easier for the sponge wiping block 18 to have a better adsorption effect when it works next time.

[0047] Example 3 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1 to 10A drain outlet 34 is fixed on one side of the water collection tank 17. A sealing plate 35 is slidably connected to both sides of the drain outlet 34. A second abutment 36 is fixed on the sealing plate 35. The sealing plate 35 is elastically connected to the drain outlet 34 through a sixth spring 37. A filter plate 38 is fixed on the drain outlet 34. A recovery water tank 39 is fixed at one end of the movable truss 1. An inlet 40 is fixed on the recovery water tank 39. A conical abutment 41 is fixed on the inlet 40.

[0048] A sliding rod 42 is fixed on the drain outlet 34. Two brush plates 43 are slidably connected to the sliding rod 42. The brush plates 43 are elastically connected to the drain outlet 34 through an eighth spring 431. The brush plates 43 abut against the surface of the filter plate 38. An abutting post 44 is fixed on the back of the brush plate 43. A conical abutting frame 45 abuts against the abutting post 44. The conical abutting frame 45 is elastically connected to the drain outlet 34 through a seventh spring 46. A strip rod 47 is fixed on the triangular abutting head 20. A second wave plate 48 is fixed on the strip rod 47. One end of the conical abutting frame 45 abuts against the second wave plate 48.

[0049] To reduce water waste and improve environmental protection, the water in collection tank 17 needs to be recycled and treated, referring to... Figures 6-9 When the C-shaped seat 5 moves to one end of the movable truss 1, the drain outlet 34 of the water collection tank 17 can be inserted into the inlet 40 of the recycling tank 39. At the same time, the conical abutment piece 41 fixed on the inlet 40 can abut against the two second abutment frames 36, causing the two second abutment frames 36 to drive the sealing piece 35 to move in opposite directions synchronously, so that the rainwater collected in the water collection tank 17 can be filtered through the filter plate 38 to improve the quality of water recycling, and the filtered rainwater flows into the recycling tank 39 for storage.

[0050] To prevent impurities from clogging the filter plate 38 and affecting the efficiency of rainwater flow, the filter holes of the filter plate 38 need to be cleaned. (Refer to...) Figures 6-9 When the hydrogen tank module 8 is lowered into the hydrogen filling equipment, the triangular contact head 20 resets, which can drive the strip rod 47 and the second wave plate 48 fixed at one end of the strip rod 47 to move horizontally synchronously, causing the second wave plate 48 to contact the conical contact frame 45, so that the conical contact frame 45 can move up and down in the drain outlet 34. The seventh spring 46 continuously stores and releases its elasticity, so that when the conical contact frame 45 contacts the contact post 44 on the brush plate 43, the brush plate 43 can move back and forth on the sliding rod 42, which can achieve the purpose of the brush plate 43 to clean the surface of the filter plate 38, thereby improving the flow rate of water in the drain outlet 34 and the filtration effect.
