[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a new energy power generation vehicle based on a hydrogen fuel cell, including a connection module 300. The connection module 300 includes a clamping component 301, a hydraulic component 302, a linkage component 305, and a flipping and fixing component 306. The clamping component 301 and the hydraulic component 302 are connected by hydraulic transmission. The hydraulic component 302 is connected to the limiting component 304 through the accommodating component 303. The hydraulic component 302 is movably connected to the linkage component 305. The linkage component 305 is movably connected to the flipping and fixing component 306.

[0031] When the generator truck provides emergency power, it needs to be connected to the terminals of the transformer to be powered using a terminal clamp. During the connection process, since the terminals may be copper busbars or copper wires, the existing terminal clamps cannot accommodate both and achieve a compatible connection.

[0032] When the device of the present invention is connected, the two sets of connection modules 300 move relative to each other, clamping the copper busbar or copper wire between the two sets of connection modules 300.

[0033] If the clamped terminal is a copper busbar, the clamping component 301 will first contact the copper busbar. The copper busbar and the clamping component 301 will squeeze each other, outputting mechanical transmission force, which will squeeze out the hydraulic oil in the clamping component 301. After the hydraulic oil enters the hydraulic component 302, it will be linked with the linkage component 305 through hydraulic transmission force, and finally drive the power supply connection end in the flipping and fixing component 306 to flip, so that the power supply connection end on the flat end contacts the terminal of the transformer to be powered.

[0034] After the remaining hydraulic oil enters the receiving component 303, it causes the limiting component 304 to be squeezed by hydraulic pressure. Its output end engages with the linkage component 305, thereby maintaining the state of the clamping component 301, so that the power supply connection end of its flat end contacts the wiring terminal of the transformer to be powered.

[0035] If the clamped terminal is a copper wire, the power supply connection end of the arc surface of the clamping component 301 contacts the terminal of the transformer to be powered, directly completing the electrical connection, thereby completing the contact power supply.

[0036] Example 2

[0037] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] The clamping assembly 301 includes a clamping frame 301a, a hydraulic chamber 301e, and a mounting cavity 301f. Both the hydraulic chamber 301e and the mounting cavity 301f are located inside the clamping frame 301a. The inner cavity of the hydraulic chamber 301e is slidably connected to a first sealing plate 301c. One end of the first sealing plate 301c is connected to a moving rod 301d, and one end of the moving rod 301d extends through to the outside of the clamping frame 301a. One end of the first sealing plate 301c is connected to a first spring 301b, and one end of the first spring 301b is connected to the inner wall of the clamping frame 301a.

[0039] The moving rods 301d in the two sets of clamping assemblies 301 have different diameters. One set of moving rods 301d has a cavity on its inner wall, and the cavity diameter is larger than the outer diameter of the other set of moving rods 301d.

[0040] When clamping and supplying power to the copper wire, the two sets of clamping components 301 move relative to each other. The moving rod 301d will not contact the copper wire. One set of moving rods 301d will move into the inner cavity of the other set of moving rods 301d, without affecting the squeezing and supplying power movement of the two sets of clamping components 301.

[0041] When clamping and supplying power to the copper busbar, the copper busbar is relatively wide. The moving rod 301d contacts the outer wall of the copper busbar and is squeezed by the copper busbar, causing it to move. The movement of the moving rod 301d drives the first sealing plate 301c to move. The movement of the first sealing plate 301c compresses the first spring 301b, causing it to deform. The deformation of the first spring 301b allows it to store elastic energy, facilitating the subsequent reset of the equipment.

[0042] The hydraulic assembly 302 includes a compression chamber 302a, a first connecting pipe 302b, a second sealing plate 302c, and a traction rod 302f. One end of the compression chamber 302a is disposed on the outer wall of the clamping frame 301a. The outer wall of the second sealing plate 302c is slidably connected to the inner wall of the clamping frame 301a. One end of the traction rod 302f is fixedly connected to the second sealing plate 302c. One end of the traction rod 302f passes through the compression chamber 302a and is connected to the transmission rod 302g. The two ends of the first connecting pipe 302b are respectively connected to the compression chamber 302a and the hydraulic chamber 301e.

[0043] The movement of the first sealing plate 301c compresses the hydraulic oil in the hydraulic chamber 301e, causing it to be squeezed out. The hydraulic oil then enters the compression chamber 302a through the first connecting pipe 302b. As the hydraulic oil continues to enter, the pressure in the hydraulic chamber 301e increases, thereby compressing the second sealing plate 302c and causing it to move. The movement of the second sealing plate 302c drives the traction rod 302f to move, which in turn drives the transmission rod 302g to move. The movement of the transmission rod 302g then drives the meshing toothed plate 305a to move, thus performing meshing transmission operations.

[0044] The hydraulic assembly 302 also includes a second spring 302d and a stop block 302e. The second spring 302d is sleeved on the outer wall of the traction rod 302f, and one end of the stop block 302e is fixedly connected to the inner wall of the clamping frame 301a. The outer wall of the clamping frame 301a is provided with a movable through groove M.

[0045] The movement of the second sealing plate 302c compresses the second spring 302d, causing it to deform. The deformation of the second spring 302d stores energy, facilitating subsequent reset operations of the equipment. The opening of the movable through slot M makes it easier to move the transmission rod 302g, avoiding interference that could affect the normal use of the equipment.

[0046] When the second sealing plate 302c moves to contact the stop block 302e, its displacement reaches the predetermined stroke. In this state, the meshing toothed plate 305a also moves to the predetermined stroke.

[0047] The linkage assembly 305 includes a meshing toothed plate 305a, a movable rod 305b, and a drive gear 305c. The outer wall of the meshing toothed plate 305a is fixedly connected to the transmission rod 302g. One end of the movable rod 305b is fixedly connected to the clamping frame 301a, and the other end of the movable rod 305b is movably connected to the drive gear 305c.

[0048] The movement of the meshing toothed plate 305a drives the driving gear 305c to rotate. The rotation of the driving gear 305c transmits the power to the driven gear 306b, causing it to rotate.

[0049] The flipping and fixing assembly 306 includes a torsion spring 306a, a driven gear 306b, a rotating rod 306c, and an arc-shaped clamping plate 306d. The torsion spring 306a and the driven gear 306b are both disposed on the outer wall of the rotating rod 306c. Both ends of the rotating rod 306c are movably connected to the clamping frame 301a. Both ends of the torsion spring 306a are respectively connected to the driven gear 306b and the clamping frame 301a. The outer wall of the rotating rod 306c is sequentially connected to a first support rod 306e and a second support rod 306f. One end of the first support rod 306e is connected to the arc-shaped clamping plate 306d, and one end of the second support rod 306f is connected to the horizontal plate 306g.

[0050] In the initial state, the arc-shaped clamping plate 306d is located on the side away from the clamping frame 301a. Both the arc-shaped clamping plate 306d and the outer wall of the horizontal plate 306g are connected to conductive devices, thereby enabling contact with the wiring terminals of the transformer to be powered and supplying electricity.

[0051] The driven gear 306b rotates the rotating rod 306c, which in turn rotates the arc-shaped clamping plate 306d and the horizontal plate 306g. The horizontal plate 306g rotates to the side away from the clamping frame 301a, thereby achieving contact with the copper busbar for power supply.

[0052] By setting the position of the stop 302e, when the second sealing plate 302c moves to contact the stop 302e, its displacement reaches the predetermined stroke. In this state, the meshing toothed plate 305a also moves to the predetermined stroke, that is, the driven gear 306b rotates 180 degrees, and the positions of the arc-shaped clamping plate 306d and the horizontal plate 306g are swapped.

[0053] The receiving assembly 303 is disposed in the installation cavity 301f. The receiving assembly 303 includes a receiving chamber 303a, a second connecting pipe 303b and a pressure relief valve 303c. One end of the receiving chamber 303a is fixedly connected to the clamping frame 301a. The pressure relief valve 303c is disposed on the outer wall of the second connecting pipe 303b. The two ends of the second connecting pipe 303b are respectively connected to the receiving chamber 303a and the compression chamber 302a.

[0054] At this state, the copper busbar continues to compress the moving rod 301d, while the second sealing plate 302c can no longer move. The oil pressure in the compression chamber 302a continues to rise, and the oil pressure exceeds the predetermined value of the pressure relief valve 303c. The hydraulic oil enters the accommodating chamber 303a through the second connecting pipe 303b.

[0055] The limiting component 304 includes a flow chamber 304a, a third spring 304b, a third sealing plate 304c, and an extension rod 304d. One end of the flow chamber 304a is fixedly connected to the inner wall of the receiving chamber 303a. The outer wall of the third sealing plate 304c is slidably connected to the inner wall of the flow chamber 304a. Both ends of the third spring 304b are connected to the third sealing plate 304c and the flow chamber 304a, respectively. One end of the extension rod 304d is connected to the third sealing plate 304c. One end of the extension rod 304d passes through the receiving chamber 303a and is connected to the positioning tooth plate 304f. A flow hole 304e is provided on the outer wall of the flow chamber 304a.

[0056] The flow chamber 304a and the receiving chamber 303a are connected through the flow hole 304e. After the oil pressure increases, the third sealing plate 304c moves due to the oil pressure. The movement of the third sealing plate 304c stretches and deforms the third spring 304b. The deformation of the third spring 304b facilitates the subsequent reset of the equipment. The movement of the third sealing plate 304c drives the extension rod 304d to move. The movement of the extension rod 304d drives the positioning tooth plate 304f to move. The movement of the positioning tooth plate 304f causes it to contact the meshing tooth plate 305a. The teeth on the surfaces of the two lock together, keeping the equipment stable and preventing shaking or tilting when clamping and energizing the copper busbar, thus ensuring the stability of the electrical connection.

[0057] Example 3

[0058] Reference Figure 1 and 7 This is the third embodiment of the present invention. This embodiment is based on the previous two embodiments and proposes a drive assembly 200 and a generator assembly 100.

[0059] The drive assembly 200 includes a drive chamber 201, a pull screw 202, and a connecting sleeve 203. One end of the pull screw 202 is movably connected to the inner wall of the drive chamber 201, and the other end of the pull screw 202 passes through the drive chamber 201 and is connected to the drive disc. A screw block 204 is threadedly connected to the outer wall of the pull screw 202. One end of the screw block 204 is connected to a guide rod 205. One end of the guide rod 205 is connected to the clamping frame 301a. One end of the connecting sleeve 203 is connected to the outer wall of the drive chamber 201.

[0060] The connecting sleeve 203 is equipped with a power supply wire to facilitate the electrical connection and power supply of the equipment, and to avoid the safety hazards caused by exposed wires during the power supply process.

[0061] When the connecting module 300 is driven to clamp and supply power, the user rotates the drive disk, which drives the pull screw 202 to rotate. The rotation of the pull screw 202 causes the two screw blocks 204 on its surface to move relative to each other. The movement of the screw blocks 204 causes the guide rod 205 to move. The movement of the guide rod 205 causes the two sets of connecting modules 300 to move relative to each other.

[0062] The drive assembly 200 also includes a limiting slide bar 207 and a limiting slide rail 208. The limiting slide rail 208 is disposed on the inner wall of the drive chamber 201. One end of the limiting slide bar 207 is slidably connected to the limiting slide rail 208, and the other end of the limiting slide bar 207 is fixedly connected to the screw block 204.

[0063] The movement of the screw block 204 causes the limiting slide bar 207 to slide within the limiting slide rail 208. The limiting slide bar 207 effectively prevents the screw block 204 from shifting or getting stuck during movement, ensuring the stability of the equipment during clamping operations.

[0064] The generator assembly 100 is connected to the connection module 300 via wires.

[0065] After the drive component 200 drives the connection module 300 to clamp the copper busbar or copper wire, the power supply operation is carried out through the generator assembly 100. The generator assembly 100 is electrically connected to the arc-shaped clamping plate 306d and the horizontal plate 306g through the connecting wire, thereby enabling the contact power supply operation of the generator.
