In order to achieve the above functions, the present invention may adopt many specific structural forms, for example: the lifting mechanism 9 can be an air cylinder, a hydraulic cylinder and the like, but the air cylinder and the hydraulic cylinder are heavy as a whole due to the fact that an air source or a hydraulic source needs to be arranged, and are inconvenient to move along with the track mechanism 12, therefore, a set of lifting mechanism 9 is developed, and the lifting mechanism 9 is compact and small in structure, good in action stability and high in accuracy.

The lifting mechanism has double limiting between the central tube 29 and the inner square tube 27 and between the outer square tube 28 and the inner square tube 27, has better stability, and simultaneously adjusts the lifting height through the rotation of the central screw 30, thereby ensuring the lifting precision.

The height information of the sliding of the outer tube 28 on the inner tube 27 is directly converted and determined by the lifting motor 31 from the rotation speed of the zero point, of course, in order to determine the position of the zero point, that is, the position of the outer tube 28 when moving to the lowest end, a lifting sensor 32 for detecting the position of the outer tube 28 on the inner tube 27 is further provided on one side of the inner tube 27, and the lifting sensor 32 may be a pressure sensor, a contact sensor, etc., as long as it can feed back a signal to the overall control system when the outer tube 28 descends to the lowest position.

In order to prevent the lubricating grease in the upper end of the central tube 29 from being pressed out from the lubricating grease inlet 33 during the relative movement between the central screw 30 and the central tube 29, a one-way valve 34 which is in one-way communication from the outside to the inside is arranged on the lubricating grease inlet 33. In addition, in order to further improve the lubricating effect on the lower end of the central screw 30, a central hole 35 is formed in the central screw 30, the central hole 35 extends from the lower part of the central screw 30 to the upper end surface of the central screw 30, and a lubricating hole 36 penetrating through the central hole 35 and the outer surface of the central screw 30 is formed in the side wall of the central screw 30. Lubricating grease can enter between the central screw 30 and the central tube 29 through the central hole 35 and the lubricating hole 36 in sequence, so that the central screw 30 is lubricated in the whole section.

The first sliding blocks 65 of the two groups of clamping assemblies are respectively in threaded fit with the two screw openings of the reciprocating screw 61, so that the two first sliding blocks 65 can move oppositely or reversely.

The clamping assembly further comprises a mounting cross plate 67 disposed between the first slider 65 and the second slider 66, and a bearing strip 68 disposed on the mounting cross plate 67. The opposite surfaces of the bearing strips 68 of the two groups of clamping components are provided with brackets 69, the brackets 69 are in an arc shape matched with the tank body of the hydrogen fuel tank 64, and a clamping area is formed between the two bearing strips 68.

In the using process of the invention, specifically, the clamping motor acts to drive the reciprocating lead screw 61 to act, and in the action process of the reciprocating lead screw 61, the first slide block 65 and the second slide block 66 of the two clamping components are driven to fold or separate along the guide rod 62, so that the transverse installation plate 67 and the bearing strip 68 on the transverse installation plate are driven to fold or separate. The refueling apparatus places the hydrogen fuel tank 64 between the two clamping assemblies or removes the hydrogen fuel tank 64 from between the two clamping assemblies. When the two clamping assemblies are closed, the two ends of the hydrogen fuel tank 64 can are placed on the brackets 69 to realize clamping. The invention can realize the quick replacement and fixation of the tank body.

In order to synchronously realize connection and release in the fixing process, the invention further comprises a sliding connection assembly, wherein the sliding connection assembly is arranged on one side of the clamping assembly corresponding to the head end of the tank body of the hydrogen fuel tank 64 and can move along with the clamping assembly, and the sliding connection assembly can be directly arranged on a first sliding block 65 and a second sliding block 66 corresponding to the clamping assembly or can be arranged on a group of first sliding blocks 65 and second sliding blocks 66 which are arranged separately and can move along with the clamping assembly. The sliding connection assembly comprises a base plate 70, the upper surface at the center of the base plate 70 is provided with a base plate 71, the top of the base plate 71 is provided with a corner plate 72 in an L shape, one side of the upper section of the corner plate 72 towards the tank body head end of the hydrogen fuel tank 64 is provided with a connection head 73, the base plate 71 is connected with the base plate 70 through a bolt, the base plate 70 is connected with the corner plate 72 through a bolt, and the corner plate 72 is connected with the connection head 73 through a bolt.

The crutch plate 72 is also provided with a pipe hole 74 for a connecting pipe butted with the connector 73 to pass through, and the connecting pipe of the vehicle 0 power system is connected with the connector 73 through the pipe hole 74. When the two sets of clamping assemblies are closed, the connector 73 is connected to the canister gas valve of the hydrogen fuel canister 64. When the clamp assemblies are separated, the adapter 73 is disengaged from the canister air valve of the hydrogen fuel canister 64.

In order to accommodate the differences in size and shape of the hydrogen fuel tanks 64 for different models of vehicles, and to improve versatility and fit, and in combination with the differences shown in fig. 15-19, the support strip 68 is preferably removably attached to the mounting cross plate 67 while maintaining stability of the attachment. For this purpose, the clamping assembly according to the present invention is provided with a joint groove 76 on the opposite side of the first slider 65 and the second slider 66, a convex joint table 77 is provided in the middle of the joint groove 76, and a notch 78 is provided at the end of the joint table 77.
