[0020] The technical solution of the present invention will be further described below through specific embodiments in combination with the accompanying drawings. The described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Example 1: Reference Figures 1 to 5A battery replacement device for an electric vehicle includes a long frame 6 connected to a battery lifting mechanism 4 that vertically moves the battery for replacement. A battery translation mechanism 3 is integrated into the battery lifting mechanism 4 to allow the battery 8 to be moved horizontally to the correct position.

[0022] It should be noted that one side of the frame 6 is connected to a pallet traversing mechanism 25, which allows the pallet 9 to move both horizontally and vertically, allowing for precise placement of batteries on the vehicle. The other side of the frame 6 is connected to a storage rack 10 for storing batteries waiting to be replaced. A mounting plate 27 is attached above the pallet traversing mechanism 25. This mounting plate 27 is designed in a cross-shaped structure for improved stability and load-bearing capacity.

[0023] What needs life is that there is a support plate 9 connected above the mounting plate 27. The size of the support plate 9 is slightly larger than the size of the battery pack. This support plate is used to fix the battery 8 to ensure the stability and safety of the battery 8 during movement.

[0024] It should be noted that a translation motor 14 is provided inside the battery translation mechanism 3. The translation motor 14 is responsible for driving the battery translation mechanism 3 so that it can move in the horizontal direction. The translation motor 14 drives the moving arm 21 through a translation rack 22. The moving arm 21 is responsible for the actual battery translation movement. The moving arm 21 is a U-shaped structure. The upper and lower parts of the moving arm 21 are long horizontal bars. There is a small connection between the two horizontal bars. A battery clamping mechanism 20 is connected to the bottom of the moving arm 21. After the battery 8 is moved to the correct position, the battery clamping mechanism 20 fixes the battery 8. The battery 8 will not be displaced during the replacement process. A lifting motor 23 is provided on the battery lifting structure 4. The lifting motor 23 drives the battery 8 to lift and lower in the vertical direction. The battery 8 can be lifted to the battery compartment of the vehicle or lowered to the storage rack 10. The lifting motor 23 is fixed on a lifting seat 15. The lifting seat 15 is a frame-shaped structure that is sleeved on the battery lifting structure 4. The lifting seat 15 is used to support the motor and ensure its stable operation.

[0025] Specific steps in this embodiment: Battery Lift Preparation: Lift motor 23 is fixed to lift base 15, which is mounted on battery lift structure 4 to ensure motor stability. Lift motor 23 is activated, driving battery 8 in a vertical direction, lifting the battery from storage rack 10 to the vehicle's battery compartment.

[0026] Preparation for battery translation: The translation motor 14 inside the battery translation mechanism 3 is started, driving the U-shaped moving arm 21 through the translation rack 22. Under the action of the translation rack 22, the horizontal bar of the moving arm 21 drives the battery 8 to move horizontally to the correct position.

[0027] Battery clamping and positioning: After the battery 8 is moved to the correct position, the battery clamping mechanism 20 under the movable arm 21 fixes the battery 8 to prevent displacement during subsequent operations.

[0028] Battery tray movement: The tray horizontal and vertical movement mechanism 25 operates to move the tray 9 horizontally and vertically to place the battery 8 on the vehicle. The tray 9 is slightly larger than the battery pack to ensure the stability and safety of the battery 8 during movement.

[0029] Battery replacement: After the battery 8 is accurately placed and fixed on the vehicle, the original battery of the vehicle is replaced by the battery 8 on the pallet 9. After the replacement is completed, the pallet horizontal and vertical moving mechanism 25 moves the replaced battery back to the storage rack 10.

[0030] Battery lowering and storage: The lifting motor 23 is started again to lower the batteries on the storage rack 10 to the storage position, ready for the next replacement.

[0031] Example 2: Reference Figures 1 to 5 The main structure of this embodiment is similar to that of Example 1, with improvements made to the lifting motor 23, battery lifting structure 4, and mounting plate 27. This battery replacement device for electric vehicles comprises a long frame 6 mounted with a battery lifting mechanism 4, which functions to vertically lift or lower the battery to facilitate replacement. Simultaneously, a battery translation mechanism 3 works in conjunction with the battery lifting mechanism 4 to allow the battery 8 to be moved horizontally to a predetermined position, ensuring accurate alignment with the vehicle's battery compartment.

[0032] It should be noted that a pallet traversing mechanism 25 is mounted at one end of the frame 6. This mechanism allows the pallet 9 to move horizontally and vertically to achieve precise positioning and installation of the batteries. A storage rack 10 is connected to the other end of the frame 6 for storing batteries to be replaced. A mounting plate 27 is mounted above the pallet traversing mechanism 25. This mounting plate adopts a cross-shaped design to enhance its stability and load-bearing capacity. A pallet 9, slightly larger than the battery pack, is further connected above the mounting plate 27 to secure the batteries 8.

[0033] It should be noted that the battery translation mechanism 3 is internally equipped with a translation motor 14, which is responsible for driving the entire translation mechanism so that the battery can move in the horizontal direction. The translation motor 14 drives the movable arm 21 through the translation rack 22, and the movable arm 21 is responsible for the actual translation of the battery. The movable arm 21 is designed as a U-shaped structure, with horizontal bars at the upper and lower ends, connected by a small section in the middle, and a battery clamping mechanism 20 connected below it. After the battery 8 moves to a predetermined position, the mechanism can fix the battery to prevent displacement during the replacement process. The battery lifting structure 4 is also equipped with a lifting motor 23, which is responsible for driving the lifting action of the battery 8 in the vertical direction, so that the battery can be lifted to the battery compartment of the vehicle or lowered to the storage rack 10. The lifting motor 23 is fixed on a lifting seat 15, which is a frame-shaped structure and is mounted on the battery lifting structure 4 to support the motor.

[0034] It should be noted that the lifting motor 23 cooperates with the lifting rack 7 on the lifting guide rail 5. The lifting guide rail 5 is a two-piece upright structure that controls the vertical lifting movement of the battery 8. The lifting process of the battery 8 is more stable and precise. The lifting guide rail 5 provides a stable movement path.

[0035] It should be noted that the rack motor 12 integrated into the battery lift structure 4 drives the rack rack 2. It is located above the U-shaped slot 13. The U-shaped slot 13 houses the track slot 11, a trapezoidal structure with a hollowed-out center slot that snaps into the rack rail 1. The battery lift structure 4 is able to move on the rack rail 1. The U-shaped slot 13 is designed to be more compact, reducing space usage and improving structural stability. The rack motor 12 works in conjunction with the rack rack 2.

[0036] It should be noted that the pallet lifting structure 16 connected above the mounting plate 27 and the pallet 9 connected above it, the pallet 9 moves in the vertical direction to adapt to the battery replacement needs at different heights. The pallet lifting structure 16 can adopt different driving methods such as hydraulic, pneumatic systems or electric push rods. The pallet 9 can be easily lifted and lowered to the appropriate position for loading and unloading batteries. The combined use of the pallet lifting structure 16 and the pallet 9 further improves the operating efficiency and safety of the electric vehicle battery replacement device, making the entire battery replacement process smoother and more reliable.

[0037] The specific operating steps of this embodiment are as follows: The main structure of this device consists of a long frame 6, on which is mounted a battery lifting mechanism 4, which is responsible for vertically moving the battery for easy replacement. The battery translation mechanism 3 works in conjunction with the battery lifting mechanism 4 to allow the battery 8 to be moved horizontally to a predetermined position, ensuring precise docking with the vehicle's battery compartment. A pallet traversing mechanism 25 is mounted on one end of the frame 6, enabling the pallet 9 to move horizontally and vertically for precise positioning and installation of the battery. The other end is connected to a storage rack 10 for storing the batteries to be replaced. A mounting plate 27 is located above the pallet traversing mechanism 25 and adopts a cross-shaped design to enhance its stability and load-bearing capacity. The pallet 9 attached above it is slightly larger than the battery pack and is used to secure the battery 8. The battery translation mechanism 3 is equipped with a translation motor 14, which drives a U-shaped moving arm 21 through a translation rack 22 to achieve horizontal movement of the battery. A battery clamping mechanism 20 is connected below the moving arm 21 to secure the battery after it has moved to the predetermined position, preventing displacement during the replacement process.

[0038] The battery lifting structure 4 is equipped with a lifting motor 23, which is responsible for driving the lifting movement of the battery 8 in the vertical direction. The lifting motor 23 is fixed on the lifting seat 15, and controls the lifting movement of the battery 8 by cooperating with the lifting rack 7 on the lifting guide rail 5, making the process smoother and more precise. The battery lifting structure 4 is also integrated with a rack motor 12, which is responsible for driving the rack rack 2. It is located above the U-shaped groove 13. The U-shaped groove 13 is provided with a track groove 11, which can be inserted into the rack guide rail 1, so that the battery lifting structure 4 can move smoothly on the guide rail. The design of the U-shaped groove 13 is compact, which reduces space occupation and enhances structural stability. Finally, the pallet lifting structure 16 connected above the mounting plate 27 and the pallet 9 connected above it allow the pallet 9 to move in the vertical direction to adapt to the battery replacement needs of different heights. The pallet lifting structure 16 can adopt different driving methods such as hydraulic, pneumatic systems or electric push rods, so that the pallet 9 can be easily lifted and lowered to the appropriate position for loading and unloading batteries.

[0039] Example 3: Reference Figures 1 to 5This embodiment is similar to the main structure of embodiment 1 or embodiment 2. On the basis of embodiment 1 or 2, additions or improvements are made to the pallet horizontal and vertical movement mechanism 25 and the disassembly and assembly structure 17. A long frame 6 is equipped with a battery lifting mechanism 4. The battery translation mechanism 3 works in conjunction with the lifting mechanism to achieve horizontal movement of the battery, ensuring that the battery can be accurately docked with the vehicle battery compartment. One end of the frame 6 is equipped with a pallet horizontal and vertical movement mechanism 25, which enables the pallet 9 to move in multiple directions to accurately position the battery; the other end is connected to the storage rack 10 for storing batteries to be replaced. The mounting plate 27 is located above the pallet horizontal and vertical movement mechanism 25 and is cross-shaped in design, which enhances stability and carrying capacity. The pallet 9 connected above it is used to fix the battery 8. The battery translation mechanism 3 is equipped with a translation motor 14, which drives the moving arm 21 through the translation rack 22 to achieve horizontal movement of the battery. The battery clamping mechanism 20 below the moving arm 21 is used to fix the battery. The battery lift structure 4 is equipped with a lift motor 23, secured to the lift base 15. This motor, in conjunction with the lift rack 7 on the lift rail 5, controls the vertical movement of the battery. Furthermore, the battery lift structure 4 incorporates a rack motor 12, which drives the rack rack 2. A U-shaped groove 13, embedded within the track groove 11, engages the rack rail 1, enabling smooth movement of the battery lift structure along the rail. Finally, the pallet lift structure 16 and pallet 9, mounted above the mounting plate 27, allow for vertical movement of the pallet 9 to accommodate battery replacement at varying heights. The pallet lift structure 16 can utilize multiple drive methods for easy battery loading and unloading.

[0040] It should be noted that the core components of the disassembly and assembly structure 17 include a positioning pin 18 and a pneumatic wrench 19. The positioning pin 18 accurately positions the battery when the battery is placed on the pallet 9, ensuring that it is in the correct loading and unloading position, avoiding loading and unloading difficulties or equipment damage due to position deviation. The pneumatic wrench 19 uses air pressure as a power source to provide torque output, making the battery fixing and disassembly work faster and more labor-saving. The buffer pads 28 are two parallel pieces placed on the pallet 9. During the process of placing the battery on the pallet 9 or removing it from the pallet 9, they reduce direct impact and vibration, protecting the battery and the pallet from damage. The positioning sensor 29 monitors the position status of the battery in real time to ensure that the battery is accurately aligned during the loading and unloading process. The sensor 29 can feed back the battery position information to the control system in real time. Once a position deviation is detected, the system can make timely adjustments to ensure that the battery is placed or removed safely and accurately. A transverse cylinder 24 is installed on one side of the pallet transverse and longitudinal movement mechanism 25, and a longitudinal cylinder 26 is installed on the other side. The support plate 9 can move in two directions. The transverse cylinder 24 is responsible for the horizontal movement of the support plate 9, and the longitudinal cylinder 26 is responsible for the vertical movement of the support plate 9.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
