[0014] Compared with the prior art, the integrated charging and battery swapping energy supply station of the present invention has the following advantages: By setting up a battery swapping cabin and a battery hoisting system, the battery swapping cabin is a cabin body suspended and fixed on multiple legs. A ceiling extending to the left is provided on the upper half of the cabin body, and a support frame plate is fixed at the left end of the ceiling, so as to form a battery swapping channel between the support frame plate and the cabin body.

Rope winding wheels are respectively fixed at both ends of the output shaft of the lifting speed reducer, and four sling assemblies corresponding to the rope winding wheels are provided on the docking frame. Among them, the four sling assemblies respectively pass around the four fixed pulleys through steel wires and are connected to the corresponding rope winding wheels. The hook assembly is provided with an intermediate connection seat fixed at the bottom of the docking frame. Side connection seats fixed at the bottom of the docking frame are respectively provided on the transverse two sides of the intermediate connection seat. A rotating shaft is installed on the side connection seat, a lifting claw is fixed at the lower end of the rotating shaft, and a cylinder is provided between the lifting claw and the intermediate connection seat. Thus, an integrated charging and battery swapping energy supply station with a simple structure, small occupied space, low construction cost, good heat dissipation effect and strong functionality is formed. In practical applications, multiple battery packs are hoisted to the battery pack support bases one by one through the battery hoisting system, and one battery pack support base is vacant. When one charging gun is inserted into the corresponding charging gun box, the battery pack at the corresponding position can be charged through the charger, the charging gun, the charging gun box and the charging connector; when the battery pack on the vehicle is out of power, the vehicle is driven to the battery swapping channel, and the discharged battery pack on the vehicle is hoisted to the vacant battery pack support base for charging through the battery hoisting system, and the fully charged battery pack is hoisted from the battery pack support base to the vehicle, so as to achieve the purpose of rapid battery swapping; when the vehicle needs temporary charging, the vehicle is driven to one side of the cabin body, and the charging gun is inserted into the vehicle charging port to directly charge the vehicle.The specific process of lifting the battery pack is as follows: First, move the battery hoist directly above the battery pack, and lower the battery hoist onto the battery pack by releasing the steel wire rope. Then, drive the corresponding lifting claws to rotate under the side beam of the support frame of the battery pack through each cylinder to hook the battery pack, thereby realizing the connection between the battery hoist and the battery pack. Next, lift the battery hoist and the battery pack by retracting the steel wire rope until the docking frame and the transverse movement frame are docked. Subsequently, move the battery pack from the charging position to the vehicle or from the vehicle to the charging position, and release the connection between the battery hoist and the battery pack. Thus, one battery lifting operation is completed. When releasing the connection between the battery hoist and the battery pack, just rotate each lifting claw to the initial position. Compared with the prior art, in the present invention, the cabin is suspended and fixed on multiple legs, and the charger is arranged under the cabin. On the one hand, the structure is simplified and the construction cost is reduced. On the other hand, the heat dissipation effect and safety reliability are improved. By arranging a charging gun on the charger and connecting the charging connector of the battery pack support to the charging gun box fixed on the outer side of the cabin, the battery pack on the battery pack support can be charged by inserting the charging gun into the charging gun box, meeting the fast battery swapping requirement. The vehicle can be directly charged by inserting the charging gun into the vehicle charging port, meeting the temporary charging requirement, and improving the functionality and practicability. By arranging a buffer mechanism between the platen and the bracket and fixing the charging connector on the platen, when the battery pack falls onto the battery pack support from top to bottom, the buffer mechanism can, on the one hand, avoid damaging the charging connector due to hard contact, and on the other hand, ensure the stable and reliable connection. In addition, in the present invention, the lifting speed reducer and the rope winding wheel originally arranged on the transverse movement frame are moved to the battery hoist, and the movable pulley originally arranged on the battery hoist is removed. On the one hand, the structural layout is optimized, and the occupied space after the battery hoist is docked with the transverse movement frame is reduced, which is beneficial to reducing the overall height and construction cost of the energy replenishment station. On the other hand, by removing the movable pulley, the path of the steel wire rope during the lifting process is shortened, and the stability of the lifting action is improved. At the same time, in the present invention, the hook assembly is provided with an intermediate connection seat, a side connection seat, a rotating shaft, a lifting claw and a cylinder. The lifting claw is directly driven to rotate by the cylinder, and compared with the prior art, transmission mechanisms such as a sliding plate, a guide hole, rollers, a guide rail and a slider are omitted, improving the stable and reliable performance.

The battery hoisting system is provided with a longitudinal moving frame 5, a transverse moving frame 6, and a battery lifting hook 7. Among them, the longitudinal moving frame 5 moves longitudinally along two longitudinal guide rails (not shown in the figure) fixed in the cabin body 2 and extending to the ceiling 21. The transverse moving frame 6 moves transversely along two transverse guide rails 51 fixed on the longitudinal moving frame 5. Four fixed pulleys 61 are symmetrically distributed on the transverse moving frame 6. The battery lifting hook 7 is provided with a docking frame 71 and two groups of hook assemblies 72 symmetrically distributed longitudinally. Two lifting speed reducers 73 are arranged on the docking frame 71. The input shaft of the lifting speed reducer 73 is connected to a lifting drive motor.

In practical applications, multiple battery packs 100 are hoisted one by one to the battery pack holders 4 through the battery hoisting system, and one of the battery pack holders 4 is vacant. When one of the charging guns 31 is inserted into the corresponding charging gun box 44, the battery pack 100 at the corresponding position can be charged through the charger 3, the charging gun 31, the charging gun box 44, and the charging connector 43; when the battery pack 100 on the vehicle has insufficient power, the vehicle 200 is driven to the swapping channel, and the discharged battery pack 100 on the vehicle is hoisted to the vacant battery pack holder 4 through the battery hoisting system for charging, and the fully charged battery pack 100 is hoisted from the battery pack holder to the vehicle 200, so as to achieve the purpose of rapid battery swapping; when the vehicle 200 needs temporary power replenishment, the vehicle is driven to one side of the cabin 2, and the charging gun 31 is inserted into the vehicle's charging port to directly charge the vehicle 200. The specific process of hoisting the battery pack 100 is as follows: First, the battery sling 7 is moved directly above the battery pack 100, and the battery sling 7 is lowered onto the battery pack 100 by releasing the wire rope 76. Then, each cylinder 725 drives the corresponding lifting claw 724 to rotate to the lower side of the support frame side beam of the battery pack 100 to hook the battery pack 100, thereby realizing the connection between the battery sling 7 and the battery pack 100. Then, the battery sling 7 and the battery pack 100 are lifted by retracting the wire rope 76 until the docking frame 71 is docked with the transverse movement frame 6. Subsequently, the battery pack 100 is moved from the charging position (battery pack holder) to the vehicle or from the vehicle to the charging position, and the connection between the battery sling 7 and the battery pack 100 is released. Thus, a battery pack hoisting is completed. When releasing the connection between the battery sling 7 and the battery pack 100, only need to rotate each lifting claw 724 to the initial position. Compared with the prior art, in the present invention, the cabin 2 is suspended and fixed on multiple legs 1, and the charger 3 is arranged under the cabin 2.

The upper end of the first lateral guide post 46 is provided with an inclined surface that is higher on the inner side and lower on the outer side in the transverse direction. The two first longitudinal guide posts 47 are symmetrically distributed on both longitudinal sides of the bracket 41.

As a specific implementation manner, the present invention fixes a grating sensor 23 and two laser sensors 24 inside the support frame plate 22. Among them, the grating sensor 23 is used to detect the relative X-direction position of the battery pack of the battery-changing vehicle to the energy replenishment station. The X-direction refers to the direction parallel to the traveling direction of the vehicle. The two laser sensors 24 are used to detect the angle of the battery-changing vehicle relative to the battery-changing channel and the relative Y-direction position of the center of the battery pack of the battery-changing vehicle to the center of the energy replenishment station. The Y-direction refers to the direction perpendicular to the traveling direction of the vehicle. This setting detects the vehicle through the grating sensor 23 and the laser sensors 24 and performs attitude control according to the detected parameters, improving the reliability of the battery-changing operation. As a specific implementation manner, the present invention also provides the battery pack holder 4 with four battery pack pads 48 and two battery pack positioning posts 49 fixed on the bottom plate of the cabin 2. Among them, the battery pack pads 48 are made of composite rubber. The four battery pack pads 48 are symmetrically distributed on both the lateral sides and the longitudinal sides of the bracket 41. The two battery pack positioning posts 49 are diagonally distributed on both sides of the bracket 41.During the falling process of the battery pack 100, this setting can avoid hard collisions through the four battery pack pads 48, reducing wear and noise. By inserting the two battery pack positioning posts 49 into the corresponding positioning holes provided on the battery pack 100, the purpose of accurate positioning is achieved.

[0040] As a specific implementation manner, as Figure 6 shown, the present invention makes the longitudinal movement frame 5 adopt the following longitudinal movement mechanism: Four longitudinal movement rollers 52 which are symmetrically distributed and are on the longitudinal guide rails are installed on the longitudinal movement frame 5, and a longitudinal movement reduction gear 53 is installed on the longitudinal movement frame 5. The input shaft of the longitudinal movement reduction gear 53 is connected to a longitudinal movement driving motor (not shown in the figure), and the two ends of the output shaft of the longitudinal movement reduction gear 53 are respectively connected to the two longitudinal movement rollers 52 through longitudinal movement transmission shafts 54. This setting drives the longitudinal movement rollers 52 to rotate forward and backward through the longitudinal movement driving motor and the longitudinal movement reduction gear 53, so that the longitudinal movement frame 5 can move longitudinally along the longitudinal guide rails, and has the characteristics of simple structure and convenient operation. It should be noted that the two longitudinal movement rollers 52 connected to the output shaft of the longitudinal movement reduction gear 53 should be symmetrically distributed in the transverse direction and correspondingly located on two longitudinal guide rails to ensure the stability and balance of the structure. As a specific implementation manner, as Figures 6 to 12 shown, the present invention makes the transverse movement frame 6 adopt the following transverse movement driving mechanism: Four transverse movement rollers 62 which are symmetrically distributed and are on the transverse guide rail 51 are installed on the transverse movement frame 6, and a transverse movement reduction gear 63 is installed on the transverse movement frame 6. The input shaft of the transverse movement reduction gear 63 is connected to a transverse movement driving motor (not shown in the figure). Active sprockets 65 are respectively installed at the two ends of the output shaft of the transverse movement reduction gear 63 through transverse movement transmission shafts 64. Driven sprockets 66 are respectively arranged on both sides of the active sprockets 65. Among them, a chain 55 with both ends fixed and corresponding to the active sprockets 65 is provided on the longitudinal movement frame 5, and the chain 55 bypasses the corresponding active sprockets 65 and driven sprockets 66 in a "J" shape. This setting drives the active sprockets 65 to rotate forward and backward through the transverse movement driving motor and the transverse movement reduction gear 63, and with the cooperation of the chain 55 and the driven sprockets 66, the transverse movement frame 6 can move transversely along the transverse guide rail 51. Compared with the prior art, by adopting the transverse movement driving form of sprocket and chain cooperation, and making the chain 55 bypass the active sprockets 65 and the two driven sprockets 66 in a "J" shape, the reliability of the transverse movement driving and the accuracy of the transverse movement control are improved. It should be noted that the present invention usually installs the transverse movement transmission shafts 64 on the transverse movement frame 6 by using bearings to improve the support stability, and fixes the active sprockets 65 on the transverse movement transmission shafts 64; similarly, the present invention fixes a support shaft on the transverse movement frame 6, and installs the driven sprockets 66 on the support shaft through bearings.

[0041] As an optimized solution, as Figures 13 to 15As shown in the figure, in this specific embodiment, a first proximity switch 77 corresponding to each of the four sling assemblies 75 is provided at the bottom of the docking frame 71, and the sling assembly 75 is structured as follows: a first guide rod 751 passing through the docking frame 71 is provided, a sling 752 of a wire rope 76 is fixedly connected to the upper end of the first guide rod 751, an adjusting nut 753 is installed at the lower end of the first guide rod 751, a spring seat 754 cooperating with the first proximity switch 77 is sleeved on the first guide rod 751 above the adjusting nut 753, and a first spring 755 is sleeved on the first guide rod 751 between the spring seat 754 and the docking frame 71. This setting will compress the first spring 755 to the minimum length under the action of the gravity of the battery hoist 7 under normal working conditions, and align the spring seat 754 with the first proximity switch 77; if the battery hoist 7 continues to release the wire rope 76 after falling onto the battery pack, the spring seat 754 will move downward under the elastic force of the first spring 755 and trigger a signal from the first proximity switch 77, achieving the purpose of detecting over-release of the wire rope, effectively avoiding the phenomenon of the wire rope being entangled and disordered due to over-release, ensuring the stability of the structure and the lifting action, and having the characteristics of simple structure and sensitive action. As an optimized solution, in this specific embodiment, four second transverse guide columns 78 distributed symmetrically are fixed at the bottom of the docking frame 71, an inclined surface with a lower inner side and a higher outer side in the horizontal direction is provided at the lower end of the second transverse guide column 78, and a transverse guard plate 781 is fixed on the inclined surface and the outer side surface of the second transverse guide column 78. Correspondingly, an inclined surface with a lower outer side and a higher inner side in the vertical direction is provided at the lower end of the intermediate connection seat 721, and a longitudinal guard plate 7211 is fixed on the inclined surface and the inner side surface of the intermediate connection seat 721. This setting can play a guiding and positioning role in the horizontal direction by using the four second transverse guide columns 78 and their inclined surfaces when the battery hoist 7 falls and docks with the battery pack, and reduce the sound and wear through the transverse guard plate 781; the intermediate connection seat 721 of the two groups of hook assemblies 72 and its inclined surface can play a guiding and positioning role in the vertical direction, and reduce the sound and wear through the longitudinal guard plate 7211. Among them, the side beam of the support frame of the battery pack 100 plays a horizontal limit and blocking role for the second transverse guide column 78, and the intermediate connection beam of the support frame of the battery pack 100 plays a vertical limit and blocking role for the intermediate connection seat 721 of the two groups of hook assemblies 72. Similarly, in this specific embodiment, an auxiliary guard plate 7221 is fixed on the outer side of the side connection seat 722, and a triangular auxiliary guard block 7241 is fixed on the outer side of the lifting claw 724 to enhance the guiding and protective effects. In practical applications, the present invention usually makes the transverse guard plate 781, the longitudinal guard plate 7211, the auxiliary guard plate 7221 and the auxiliary guard block 7241 made of nylon materials.

[0042] As an optimized solution, as Figures 13 to 15 and Figure 20As shown in the figure, in this specific embodiment, a descending-in-place detection component 79 is installed on the docking frame 71, and the descending-in-place detection component 79 adopts the following structure: an L-shaped bracket 791 is fixed on the docking frame 71, two second proximity switches 792 are fixed on the vertical part of the L-shaped bracket 791, a second guide rod 794 is installed on the horizontal part of the L-shaped bracket 791 through a guide sleeve 793, a retaining ring 795 is arranged at the lower end of the second guide rod 794, a second spring 796 is sleeved on the second guide rod 794 between the retaining ring 795 and the guide sleeve 793, and a limit sleeve 797 that cooperates with the second proximity switches 792 is fixed at the upper end of the second guide rod 794. When the battery hoist 7 descends and docks with the battery pack 100, the support frame of the battery pack 100 will block the second guide rod 794 and compress the second spring 796 through the retaining ring 795. When the battery hoist 7 descends in place, the limit sleeve 797 will trigger signals for both second proximity switches 792, thus achieving the purpose of in-place detection. At this time, the battery pack can be hooked by rotating the lifting claw 724; after hooking the battery pack, when the battery hoist 7 ascends and moves with the battery pack, the upper second proximity switch 792 will lose the signal due to a small distance between the docking frame 71 and the support frame of the battery pack. At this time, only the lower second proximity switch 792 has a triggered signal, indicating that the battery pack is on the battery hoist 7, playing a safety reminder role and avoiding misoperation; when the battery hoist 7 disconnects from the battery pack 100 and leaves, the second guide rod 794 and the limit sleeve 797 will automatically reset under the action of the second spring 796. In practical applications, to ensure the reliability of detection, the present invention usually sets two descending-in-place detection components 79 and distributes them on both sides of the docking frame 71. As an optimized solution, this specific embodiment also fixes two descending limit supports 711 and two hoist positioning columns 712 on the docking frame 71. Among them, the two descending limit supports 711 are correspondingly arranged at the horizontal two-side positions of the docking frame 71, and a buffer pad 713 made of rubber material is fixed at the bottom of the descending limit support 711. The two hoist positioning columns 712 are arranged on the upper side of the docking frame 71 and are diagonally distributed, and a positioning cylinder 67 that cooperates with the hoist positioning columns 712 is fixed at the bottom of the transverse movement frame 6. When the battery hoist 7 descends and docks with the battery pack 100, the buffer pad 713 will first contact the support frame of the battery pack 100 and play a buffering role; when the battery hoist 7 ascends and docks with the transverse movement frame 6, inserting the two hoist positioning columns 712 into the corresponding positioning cylinders 67 can keep the battery hoist 7 and the transverse movement frame 6 relatively fixed, improving the stability during the movement process.

[0043] As a specific embodiment, the present invention arranges the air cylinder 725 as follows: a transfer member 7212 is fixed on the intermediate connection seat 721, and a hinge member 7242 is fixed on the lifting claw 724. The two ends of the air cylinder 725 are respectively connected to the transfer member 7212 and the hinge member 7242 through pins. This arrangement improves the smoothness of the rotation movement of the lifting claw 724 by using a hinge connection for the air cylinder 725. To ensure the stability of the structure and movement, the present specific embodiment arranges the rotating shaft 723 as follows: a collar 7231 is provided on the peripheral wall of the rotating shaft 723, a locking nut 7232 is installed at the upper end of the rotating shaft 723, a pressure plate 7233 is fixed to the top of the rotating shaft 723 by screws, a limit ring 7222 is provided on the inner wall of the shaft hole of the side connection seat 722, and roller bearings 726 are respectively installed between the limit ring 7222 and the collar 7231 and the locking nut 7232. This arrangement is characterized by simple structure, convenient disassembly and assembly, and stable and reliable. In practical applications, to ensure the installation convenience and connection stability of the hook assembly 72, the present invention provides an intermediate seat mounting plate at the top of the intermediate connection seat 721, which is fixed to the bottom of the docking frame 71 by bolts, a side seat mounting plate at the top of the side connection seat 722, which is fixed to the bottom of the docking frame 71 by bolts, and a side plate extending upward and fixed to the outside of the docking frame 71 by bolts is provided on the outside of the side connection seat 722.

[0044] As a specific embodiment, to prevent the transverse movement frame 6 from disengaging from the transverse guide rail 51 during movement, the present invention respectively provides two longitudinal limiting components 68 arranged at intervals in the longitudinal direction on both longitudinal sides of the transverse movement frame 6, and the longitudinal limiting components 68 are structured as follows: a transfer support 681 is fixed on the transverse movement frame 6 by bolts, a horizontal limiting roller 682 is installed on the transfer support 681, and the limiting roller 682 uses a roller bearing. This arrangement is characterized by simple structure, low cost, and stable and reliable. During the movement of the transverse movement frame 6 along the transverse guide rail 51, each limiting roller 682 is respectively pressed against the corresponding track provided on the longitudinal movement frame 5, so as to play a limiting and guiding role without affecting the movement. In practical applications, to prevent the longitudinal movement frame 5 from disengaging from the longitudinal guide rail during movement, the present invention also provides a transverse limiting component on the longitudinal movement frame 5 with the same structure as the longitudinal limiting component 68. As a specific embodiment, to prevent the transverse movement frame 6 from exceeding the safe movement range, the present invention respectively fixes baffles 69 on both transverse sides of the transverse movement frame 6, and a buffer plate 610 made of rubber material is fixed on the baffles 69. Correspondingly, a limiting block 56 made of rubber material and cooperating with the baffles 69 and the buffer plate 610 is fixed on the longitudinal movement frame 5.
