[0033] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The embodiment of the present invention provides a hydrogenation machine with an automatic hydrogenation function, such as Figure 1-14 As shown, the hydrogenator with automatic hydrogenation function includes: a hydrogenator body 1 and a hydrogenation gun 2 arranged on the hydrogenator body 1, on which a gun head 3 is threadedly mounted; a mechanical arm 4 for automatically hydrogenating a vehicle arranged on one side of the hydrogenator body 1, and an electric gripper 5 arranged on the mechanical arm 4 for grabbing the hydrogenation gun 2; a hydrogen leakage detection system 17 installed on one side of the hydrogenator body 1 for monitoring hydrogen leakage; and an operating mechanism arranged on the mechanical arm 4 for opening the hydrogenation port cover and the dust cap in the automobile hydrogen supply system.

[0035] In this embodiment, the vehicle is first guided by the vehicle position prompting mechanism 30 and stops at the designated hydrogen refueling position, after which the intelligent monitoring device 6 starts to work in coordination with the robotic arm 4, which automatically opens the vehicle's hydrogen refueling port cover and the dust cap in the vehicle's hydrogen supply system through the operating mechanism installed thereon.

[0036] After the hydrogen filling port cover and the dust cap are opened, the electric gripper 5 on the robot arm 4 grabs the hydrogen filling gun 2 and accurately inserts its gun head 3 into the hydrogen filling port of the vehicle. After the hydrogen filling gun 2 is successfully docked with the vehicle's hydrogen filling port, the hydrogen filling operation begins. During the hydrogen filling process, the hydrogen leak detection system 17 continues to work to monitor in real time whether there is any hydrogen leakage.

[0037] Through automated operation, human participation is reduced, thereby reducing the risk of safety accidents such as fire and leakage caused by operational errors. Especially for hydrogen energy, which is a raw material that is very different from traditional oil, automated operation can more strictly follow operating specifications to ensure the safety of the hydrogenation process. The automated hydrogenation process can complete the hydrogenation task quickly and accurately, which greatly improves the operating efficiency of the hydrogenation station compared to manual operation. Through the collaborative operation of the intelligent monitoring equipment 6 and the robotic arm 4, as well as the real-time monitoring of the hydrogen leak detection system 17, an intelligent hydrogenation environment is jointly formed.

[0038] In a further preferred embodiment of the present invention, the operating mechanism includes: a connection box 7 fixedly mounted on the robotic arm 4, on which an intelligent monitoring device 6 is installed; a group of brackets 8 all arranged on the connection box 7; an electric suction cup 9 for opening the hydrogen filling port cover and a grabbing clamp 10 for unscrewing the dust cap respectively installed on a group of the brackets 8; and a moving mechanism arranged on the connection box 7 for adjusting the positions of the grabbing clamp 10 and the electric suction cup 9.

[0039] In this embodiment, the moving mechanism first adjusts the position of the gripper 10 and the electric suction cup 9, so that the electric suction cup 9 moves forward to the vicinity of the hydrogen filling port cover, and the gripper 10 moves backward to avoid interference. After the electric suction cup 9 absorbs the hydrogen filling port cover, it cooperates with the robot arm 4 to open the hydrogen filling port cover. After the hydrogen filling port cover is opened, the moving mechanism adjusts the position of the gripper 10 and the electric suction cup 9 again, so that the gripper 10 moves forward to the vicinity of the dust cap. After the gripper 10 clamps the dust cap, it is unscrewed by the rotation of the robot arm 4 to facilitate subsequent hydrogenation operations. Through the coordinated action of the electric suction cup 9 and the gripper 10, and the precise adjustment of the moving mechanism, the hydrogen filling port cover can be opened and the dust cap can be unscrewed more safely and accurately, avoiding damage or safety accidents caused by improper operation.

[0040] In a further preferred embodiment of the present invention, the moving mechanism includes: a group of one-way screws 11 rotatably installed in the connecting box 7; sliders 12 respectively threadedly mounted on a group of the one-way screws 11, and a group of the sliders 12 are respectively fixedly connected to a group of the brackets 8; sprockets 13 respectively fixedly mounted on a group of the one-way screws 11; a chain 14 mounted on a group of the sprockets 13; a motor 15 fixedly installed in the connecting box 7 for driving a group of the one-way screws 11 to rotate, and a bevel gear 16 is fixedly mounted on the motor 15 and any one of the one-way screws 11, and the two bevel gears 16 are meshed with each other.

[0041] In this embodiment, when it is necessary to adjust the positions of the electric suction cup 9 and the gripper 10, the motor 15 is started. Since the motor 15 and any one-way screw 11 are fixedly sleeved with a meshing bevel gear 16, when the motor 15 rotates, it will drive the two one-way screws 11 to rotate synchronously. Since the thread directions of the two one-way screws 11 are opposite, when they rotate synchronously, they will respectively drive the two sliders 12 to slide in opposite directions. The two sliders 12 are respectively fixedly connected to the electric suction cup 9 and the gripper 10, so their sliding will drive the electric suction cup 9 and the gripper 10 to move forward and backward respectively. By driving the motor 15, the positions of the electric suction cup 9 and the gripper 10 can be adjusted at the same time, thereby realizing the rapid and accurate execution of the preparation work before hydrogenation.

[0042] In a further preferred embodiment of the present invention, a top plate 18 is installed on the top of the hydrogenator body 1, a connecting frame 19 is slidably provided on the top plate 18, and a fan 20 for blowing away leaked hydrogen is installed on the connecting frame 19.

[0043] In this embodiment, during the hydrogenation process, the hydrogen leak detection system 17 continues to work and monitors in real time whether there is any hydrogen leakage. Once the hydrogen leak detection system 17 detects a hydrogen leak, the intelligent control system carried by the hydrogenator body 1 immediately responds automatically. The intelligent control system automatically turns on the fan 20 installed on the top plate 18. The fan 20 slides to a suitable position on the top plate 18 through the connecting frame 19 to blow away the accumulated hydrogen to avoid accidents. By adding the fan 20 and the intelligent control system, when the hydrogen leak detection system 17 detects a hydrogen leak, the emergency response mechanism can be quickly activated to blow away the accumulated hydrogen, effectively reducing the risk of accidents.

[0044] In a further preferred embodiment of the present invention, a connecting plate 21 is fixedly mounted on the top plate 18, a threaded cylinder 22 is rotatably mounted on the connecting plate 21, a threaded rod 23 for driving the fan 20 to move is threadedly sleeved on the threaded cylinder 22, one end of the threaded rod 23 is fixedly connected to the connecting frame 19, a motor 24 is provided above the top plate 18, a driving gear 25 is installed on the output shaft of the motor 24 and the threaded cylinder 22, and the two driving gears 25 are meshed with each other.

[0045] In the present embodiment, when the hydrogen leak detection system 17 detects a hydrogen leak, the intelligent control system automatically turns on the motor 24, and the output shaft of the motor 24 drives the driving gear 25 to rotate. Since the two driving gears 25 are meshed, the threaded barrel 22 will be driven to rotate synchronously. The rotation of the threaded barrel 22 will then drive the threaded rod 23 to move under the action of the thread. One end of the threaded rod 23 is fixedly connected to the connecting frame 19, so the movement of the threaded rod 23 will drive the connecting frame 19 and the fan 20 mounted thereon to move together, so that the fan 20 slides to the left, away from the top plate 18, to adjust to a suitable blowing position. After the fan 20 moves to a suitable position, the intelligent control system controls the fan 20 to start and blow away the gathered hydrogen. By adding components such as the motor 24, the threaded barrel 22, the threaded rod 23 and the driving gear 25, the automatic adjustment of the position of the fan 20 is achieved, and the emergency response capability is effectively enhanced.

[0046] In a further preferred embodiment of the present invention, a dust cover 26 is fixedly installed on the top of the top plate 18, and the dust cover 26 is arranged on the fan 20 and the threaded rod 23. A guide mechanism 27 for guiding the connecting frame 19 is provided on the top plate 18, and the guide mechanism 27 includes a guide groove, a guide rod and a connecting block. The guide groove is opened on the top plate 18, and the guide rod is fixedly installed in the guide groove. The connecting block is slidably installed on the guide rod, and the connecting block is fixedly connected to the connecting frame 19.

[0047] In this embodiment, the dust cover 26 is provided on the fan 20 and the threaded rod 23, which effectively prevents dust and debris from entering the working area of ​​the fan or the threaded rod 23, thereby ensuring the cleanliness and operating efficiency of the equipment. When the threaded rod 23 drives the connecting frame 19 to move, the connecting block will slide smoothly along the guide rod to guide the fan 20.

[0048] In a further preferred embodiment of the present invention, a support wheel for supporting the connecting frame 19 is fixedly mounted on the bottom of the connecting frame 19 , and the support wheel is in contact with the top of the top plate 18 .

[0049] In this embodiment, when the threaded rod 23 moves under the drive of the threaded barrel 22, it will drive the connecting frame 19 to move together. At this time, the support wheels at the bottom of the connecting frame 19 will roll on the top of the top plate 18, providing additional support and guidance for the movement of the connecting frame 19. At the same time, the connecting block slides on the guide groove and guide rod of the guide mechanism, further ensuring the smoothness and accuracy of the movement of the connecting frame 19.

[0050] In a further preferred embodiment of the present invention, an arc plate 28 for pressing the switch of the hydrogenation gun 2 is rotatably installed at the bottom of the connecting box 7, and an electric telescopic rod 29 is hinged on one side of the connecting box 7, and the bottom end of the electric telescopic rod 29 is hinged to the arc plate 28.

[0051] In this embodiment, under the precise control of the robot arm 4, the gun head 3 of the hydrogenation gun 2 is accurately inserted into the hydrogenation port of the vehicle. When the hydrogenation gun 2 is docked with the hydrogenation port of the vehicle, the intelligent control system controls the electric telescopic rod 29 to extend and retract. When the telescopic rod is extended, it will push the arc plate 28 to rotate to the right, thereby pressing the switch of the hydrogenation gun 2 to start the hydrogenation operation. After the hydrogenation operation is completed, the intelligent control system controls the electric telescopic rod 29 to retract again. When the telescopic rod is retracted, the arc plate 28 rotates to the left and away from the switch of the hydrogenation gun 2, thereby releasing the switch and ending the hydrogenation operation. By adding the arc plate 28 and the electric telescopic rod 29, the automatic pressing and releasing of the hydrogenation gun switch is realized, which further improves the automation degree of the hydrogenation operation. By eliminating the need for manual pressing of the switch of the hydrogenation gun 2, the operation difficulty and labor intensity are reduced.

[0052] In a further preferred embodiment of the present invention, a vehicle position prompting mechanism 30 is provided on the ground on the front side of the hydrogenation machine body 1, and the vehicle position prompting mechanism 30 includes: a mounting groove opened on the ground and a fixing plate 301 fixedly installed in the mounting groove; a pressure plate 302 provided in the mounting groove; a pressure rod 303 fixedly installed at the bottom of the pressure plate 302, and the pressure rod 303 slides through the fixing plate 301; a switch device 304 fixedly installed at the bottom of the mounting groove; a reset spring 305 sleeved on the pressure rod 303, and the two ends of the reset spring 305 are respectively fixedly connected to the fixing plate 301 and the pressure plate 302.

[0053] In this embodiment, when the vehicle is ready to perform hydrogenation operation, the driver parks the front wheels of the vehicle on the vehicle position prompting mechanism 30. At this time, the front wheels of the vehicle press down the pressure plate 302, push the pressure rod 303 to move and trigger the switch device 304 to open for the first time. After the switch device 304 is turned on for the first time, a signal is sent to the intelligent control system of the hydrogen filling machine body 1. If the rear wheels of the vehicle have not been parked in place at this time, the intelligent control system will not immediately confirm the vehicle position. When the rear wheels of the vehicle are also parked on the vehicle position prompting mechanism 30 and press down the pressure plate 302, the pressure rod 303 moves again and triggers the switch device 304 to open for the second time.

[0054] After the switch device 304 is turned on for the second time, the intelligent control system confirms that the vehicle has been parked at the designated location and displays relevant information on the display screen of the hydrogen filling machine body 1, prompting the driver to perform subsequent hydrogen filling operations. If the display screen does not display information that the vehicle has been parked at the designated location, it means that the vehicle parking position is inaccurate. At this time, the driver needs to adjust the vehicle position until the correct information is displayed on the display screen. The vehicle position prompting mechanism 30 can accurately prompt the driver to park the vehicle at the designated location, thereby avoiding delays in hydrogen filling operations due to inaccurate parking positions and improving hydrogen filling efficiency.

[0055] In a further preferred embodiment of the present invention, a sealing ring 306 is installed at the bottom of the pressing plate 302, and the sealing ring 306 is in close contact with the inner wall of the installation groove.

[0056] In this embodiment, the sealing ring 306 is provided to prevent moisture, dust or other impurities from accumulating in the installation groove. When the pressure plate 302 is pressed down by the vehicle tire, the sealing ring 306 can maintain its shape and fit tightly against the inner wall of the installation groove, thereby effectively preventing external contaminants from entering the interior of the installation groove.

[0057] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0058] In another embodiment of the present invention, an automatic replacement mechanism for automatically replacing the gun head 3 of the hydrogenation gun 2 is provided on one side of the hydrogenation machine body 1, and the automatic replacement mechanism includes: a box body 31 fixedly installed on one side of the hydrogenation machine body 1; a connecting frame 32 rotatably installed in the box body 31; an electric telescopic rod 2 33 fixedly installed on the connecting frame 32 for clamping the gun head 3, and a clamping block 34 is installed on the output rod of the electric telescopic rod 2 33; a motor 35 fixedly installed on the top of the box body 31 for driving the connecting frame 32 to rotate, and the output shaft of the motor 35 is fixedly connected to the rotating shaft of the connecting frame 32; and a replacement mechanism provided in the box body 31 for moving and replacing the old gun head 3.

[0059] In this embodiment, when the gun head 3 of the hydrogenation gun 2 needs to be replaced, the hydrogenation gun 2 (with the old gun head) is first moved to the clamping position of the connecting frame 32 by the mechanical arm 4, then the electric telescopic rod 2 33 is started, and its output rod drives the clamping block 34 to move toward the gun head 3 and clamp the gun head 3, then the motor 3 35 is started, and its output shaft drives the connecting frame 32 to rotate. During the rotation process, the mechanical arm 4 drives the hydrogenation gun 2 to slide down, so that the clamping device (i.e., the clamping block 34 and the gun head 3) on the connecting frame 32 can unscrew the old gun head from the hydrogenation gun 2;

[0060] Afterwards, the robotic arm 4 drives the hydrogenation gun 2 away from the box body 31. At this time, the replacement mechanism starts to work, removes the old gun head 3 from the connecting frame 32, and replaces it with a new gun head 3. Finally, the motor 35 is started again, driving the connecting frame 32 to rotate back to its original position. The robotic arm 4 moves the hydrogenation gun 2 to the connecting frame 32 again, and installs the new gun head 3 on the hydrogenation gun 2 through the clamping device.

[0061] In another embodiment of the present invention, the replacement mechanism includes: a collection box 36 slidably arranged in the box body 31 for collecting old gun tips 3; a placement box 37 fixedly installed on the top of the collection box 36 for placing new gun tips 3; a connecting cover 43 fixedly installed on one side of the box body 31; a rack 38 fixedly installed on one side of the collection box 36, and the rack 38 passes through the connecting cover 43 and one side of the box body 31; a driven gear 39 fixedly installed in the connecting cover 43, and the driven gear 39 is meshed with the driven rack 38; a linkage mechanism provided on the driven gear 39 and the threaded barrel 22 for synchronously driving the driven gear 39 and the threaded barrel 22 to rotate.

[0062] In this embodiment, after the old gun head 3 is replaced, the robot arm 4 moves away from the box body 31, and then the motor 2 is started to make the linkage mechanism run synchronously, thereby driving the driven gear 1 39 to rotate, so that the driven gear 1 39 drives the rack 1 38 to drive the collection box 36 and the placement box 37 to move. When the collection box 36 moves to the specified position, the electric telescopic rod 2 33 contracts, so that the old gun head 3 falls into the collection box 36, and then the motor 2 24 is started again to make the rack 1 38 continue to move to one side, so that the placement box 37 drives the new gun head 3 to move between the two clamps 34. The new gun head 3 is clamped by the clamp 34, which is convenient for subsequent installation on the hydrogenation gun 2. The new and old gun heads 3 are quickly replaced by the automated mechanism, which significantly improves the replacement efficiency.

[0063] In another embodiment of the present invention, a limiting plate 40 is rotatably installed at the bottom of the placement box 37, and the limiting plate 40 is L-shaped and used to limit the new gun head 3. A connecting block 42 is fixedly installed at the bottom of the limiting plate 40, and a connecting spring 41 is installed below the placement box 37, and one end of the connecting spring 41 is fixedly connected to the connecting block 42.

[0064] In this embodiment, after the clamp 34 fixes the new gun head 3, the placement box 37 starts to slide to the right to reset. During the resetting process of the placement box 37, due to the limiting effect of the new gun head 3, the limiting plate 40 will rotate accordingly. At the same time, the connecting spring 41 is deformed due to the rotation of the limiting plate 40 and stores elastic force. When the limiting plate 40 moves away from the gun head 3 as the placement box 37 moves, the connecting spring 41 starts to release the elastic force stored previously. This elastic force pushes the limiting plate 40 to rotate and reset, preparing for the next placement of the gun head 3.

[0065] In another embodiment of the present invention, the linkage mechanism includes: a connecting cover 43 respectively installed on the box body 31 and the top plate 18; a rotating rod 44 rotatably installed on the two connecting covers 43; a connecting rod rotatably installed in the connecting cover 43 located on the top plate 18; two groups of bevel gears 2 45 respectively fixedly mounted on the driven gear 1 39, the two ends of the rotating rod 44 and the connecting rod, and the two groups of bevel gears 2 45 are meshed with each other; a sprocket 2 46 respectively fixedly mounted on the connecting rod and the threaded cylinder 22; a chain 2 47 mounted on the two sprockets 2 46, and the chain 2 47 is meshed with the two sprockets 2 46; a limiting wheel 48 rotatably installed on one side of the connecting plate 21 for limiting the chain 2 47.

[0066] In this embodiment, while the motor 24 drives the threaded barrel 22 to rotate, it transmits the force to the sprocket 2 46 on the connecting rod through the sprocket 2 46 and the chain 2 47. At the same time, the connecting rod meshes with the bevel gear 2 45 on the rotating rod 44 through the bevel gear 2 45 thereon, and transmits the rotational force to the rotating rod 44. The rotation of the rotating rod 44 is then meshed with the driven gear 1 39 through the bevel gear 2 45 at the other end thereof, thereby realizing the synchronous rotation of the driven gear 1 39. During the entire transmission process, the limiting wheel 48 plays the role of limiting the chain 2 47 to ensure that the chain will not fall off or be misplaced. Through the design of the linkage mechanism, the synchronous rotation of the threaded barrel 22 and the driven gear 1 39 is realized, thereby improving the overall coordination and efficiency of the equipment.

[0067] In another embodiment of the present invention, an L-shaped plate 49 is rotatably installed on one side of the box body 31, and a cover plate 50 is fixedly installed on one side of the L-shaped plate 49. The cover plate 50 and the L-shaped plate 49 are adapted to the operation port of the box body 31, and a driven gear 2 51 is fixedly sleeved on the rotating shaft of the L-shaped plate 49. An electric telescopic rod 3 52 is fixedly installed on the top of the box body 31, and a rack 2 53 is installed on the electric telescopic rod 3 52, and the rack 2 53 is meshed with the driven gear 2 51.

[0068] In this embodiment, in the initial state, the L-shaped plate 49 and the cover plate 50 jointly close the operating port of the box body 31 to prevent external dust or impurities from entering. When the gun tip 3 needs to be replaced, the electric telescopic rod three 52 begins to extend, driving the rack two 53 to slide downward. Since the rack two 53 is meshed with the driven gear two 51, the downward movement of the rack two 53 will drive the driven gear two 51 to rotate, thereby driving the L-shaped plate 49 and the cover plate 50 to open outward to expose the operating port. After the operating port is exposed, the gun tip 3 can be replaced. After the operation is completed, the electric telescopic rod three 52 is shortened, driving the rack two 53 to slide upward, so that the L-shaped plate 49 and the cover plate 50 re-close the operating port.

[0069] In another embodiment of the present invention, a storage mechanism for storing the connecting pipe 58 of the hydrogenation gun 2 is fixedly installed on one side of the hydrogenation machine body 1, and the storage mechanism includes: a storage box 54 fixedly installed on one side of the hydrogenation machine body 1; a rotating drum 55 rotatably installed in the storage box 54 for storing the connecting pipe 58; a rotating joint 56 installed on one side of the storage box 54 for connecting the output pipeline of the hydrogenation machine body 1 and the connecting pipe 58; a heater 57 installed in the storage box 54 for preventing hydrogen from freezing in the connecting pipe 58; and a motor 59 fixedly installed on one side of the storage box 54 for driving the rotating drum 55 to rotate, and the output shaft of the motor 59 is fixedly connected to the rotating shaft of the rotating drum 55.

[0070] In this embodiment, before hydrogen is added to the fuel cell vehicle, it is usually cooled to about -40 degrees Celsius by a cooling device. This precooling process helps to ensure the safety of the hydrogenation process, but it may also cause the temperature of the hydrogenation gun 2 and its related components (including the connecting pipe 58) to decrease, increasing the risk of icing.

[0071] Before hydrogenation is performed on the vehicle, the heater 57 is first started to heat the connecting pipe 58. The operation of the heater can ensure that the temperature in the connecting pipe 58 is maintained within a safe range to prevent the hydrogen from freezing due to excessively low temperature. At the same time, the motor 4 59 is started to drive the drum 55 to rotate and release the connecting pipe 58. By controlling the rotation direction and speed of the motor 4 59, the length of the connecting pipe 58 can be easily adjusted to meet the hydrogenation requirements at different distances. When the connecting pipe 58 is released to an appropriate length, the robot arm 4 clamps the hydrogenation gun 2 and connects it to the hydrogenation port of the fuel cell vehicle to perform hydrogenation operations.

[0072] In another embodiment of the present invention, a transverse plate 60 is fixedly installed on the bottom of the inner wall of the storage box 54, and two driving wheels 61 are rotatably installed on the transverse plate 60, and belts 62 are sleeved on the two driving wheels 61, and a guide cylinder 63 is installed on the belt 62, and the guide cylinder 63 is sleeved on the connecting tube 58 for guiding the connecting tube 58; an annular guide frame 64 for limiting the guide cylinder 63 is fixedly installed on one side of the transverse plate 60, and a guide block 65 is fixedly installed on the support rod of the guide cylinder 63, and the guide block 65 is slidably connected with the annular guide frame 64, and a round rod is rotatably installed on one side of the inner wall of the storage box 54, and a bevel gear three 66 is fixedly sleeved on the round rod and the driving wheel 61, and the two bevel gears three 66 are meshed with each other, and a sprocket three 67 is fixedly sleeved on the other end of the round rod and the rotating shaft of the rotating cylinder 55, and a chain three 68 is sleeved on the sprocket three 67.

[0073] In this embodiment, when the connecting tube 58 needs to be stored or released, the rotating drum 55 starts to rotate, and the rotation of the rotating drum 55 is transmitted to the round rod through the sprocket three 67 and the chain three 68. The rotation of the round rod is transmitted to the driving wheel 61 through the bevel gear three 66, so that the driving wheel 61 rotates on the cross plate 60. The rotation of the driving wheel 61 drives the belt 62 to move, and then drives the guide drum 63 to rotate along the belt 62. Driven by the belt 62, the guide drum 63 moves along the annular guide frame 64. As the guide drum 63 moves, the connecting tube 58 is evenly wound on the rotating drum 55 or released from it.
