Detailed implementation manner

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0026] The present invention provides a battery lifting mechanism for a heavy truck battery swapping station, as Figures 1 to 3 shown, which includes a support frame 1, and a lifting mechanism is provided at one end of the support frame 1;

[0027] The lifting mechanism includes a drive mechanism 2, a moving component 3, a connecting rod 4, a mounting bracket 5, a fixing block 6, a locking block 7, an adjusting component 8, an electric telescopic column 9, and a fixing plate 10. The drive mechanism 2 is located at the top of one end of the support frame 1. A moving component 3 is provided at the bottom of the drive mechanism 2. A connecting rod 4 is fixedly installed at the bottom of the moving component 3. A mounting bracket 5 is provided at the bottom of the connecting rod 4. A fixing block 6 is fixedly installed in the middle of the top of the mounting bracket 5. Both the fixing block 6 and the top of the mounting bracket 5 are fixedly installed with the connecting rod 4. An adjusting component 8 is provided inside the fixing block 6. A locking block 7 is provided at the bottom of the mounting bracket 5. Electric telescopic columns 9 are provided on both sides of the mounting bracket 5 and the adjusting component 8. A fixing plate 10 is fixedly installed at the bottom of the electric telescopic column 9.

[0028] The drive mechanism 2 drives the moving component 3, the connecting rod 4, and one end of the mounting bracket 5 to the top of the battery. The battery is locked by the locking block 7. The support frame 1 facilitates the drive mechanism 2 to drive the moving component 3, the connecting rod 4, and the mounting bracket 5 to move back and forth, thereby facilitating the replacement and installation of the battery. By installing the adjusting component 8 inside the fixing block 6, when the locking block 7 drives the battery to move away from the heavy truck, the adjusting component 8 is started to make the electric telescopic column 9 and the fixing plate 10 move, so that the electric telescopic column 9 and the fixing plate 10 move to the side close to the battery. Then, the electric telescopic column 9 is started to drive the fixing plate 10 to extend, so that the fixing plate 10 moves to the bottom of the battery and fits with its bottom, so that the electric telescopic column 9 and the fixing plate 10 can support and fix both sides of the battery, improving the stability of the battery during lifting. To prevent the battery from shaking due to the excessive speed change of the drive mechanism 2 and the moving component 3 during startup, stop, or operation during the lifting process, which affects the stability of the battery lifting and is not conducive to improving the efficiency of battery replacement.

[0029] As shown Figures 3 to 6 in the figure, the adjusting assembly 8 includes a motor 81, a rotating rod 82, a movable plate 83, a rotating plate 84, a movable block 85, a connecting plate 86, and a first electric push rod 87;

[0030] The output end of the motor 81 is drivingly connected to the rotating rod 82. The bottom end of the rotating rod 82 is rotatably connected along the inner wall of the bottom of the fixed block 6. The bottom end of the rotating rod 82 is threadedly connected to the movable plate 83. Both sides of the movable plate 83 are slidably connected to the inner wall of the fixed block 6. Both ends of the movable plate 83 are hinged to the rotating plate 84. One end of the rotating plate 84 is hinged to the movable block 85. The bottom of the movable block 85 is slidably connected to the inner wall of the bottom of the fixed block 6. One end of the movable block 85 is fixedly installed with the connecting plate 86. On both sides of the bottom of the end of the connecting plate 86 away from the fixed block 6, the first electric push rods 87 are fixedly installed. On both sides of the fixed block 6, movable openings are provided. The top of the motor 81 is fixedly installed with the inner wall of the top of the fixed block 6. The bottom of the connecting plate 86 is movably connected to the inner wall of the bottom of the fixed block 6, and one end of it passes through the movable opening and extends to both sides of the mounting bracket 5. One end of the first electric push rod 87 is fixedly installed with the electric telescopic column 9.

[0031] After the battery of the heavy truck is taken out and moved to the top of the heavy truck, first start the first electric push rod 87 to push the electric telescopic column 9 and the fixing plate 10 to move to both ends of the battery. Then, start the motor 81 to drive the rotating rod 82 to rotate along the inner wall of the bottom of the fixed block 6. Through the limitation that both sides of the rotating plate 84 slide along the inner wall of the fixed block 6, the rotating plate 84 can move upward along the rotating rod 82, so that one end of the rotating plate 84 deflects upward, and the other end drives the movable block 85 to move along the inner wall of the bottom of the fixed block 6 in the direction close to the rotating rod 82. Furthermore, the movable block 85 drives the connecting plate 86 and the first electric push rod 87 to move into the fixed block 6 through the movable opening, so that the electric telescopic column 9 drives the fixing plate 10 to move in the direction of the mounting bracket 5. When the electric telescopic column 9 approaches both sides of the battery, start the electric telescopic column 9 to drive the fixing plate 10 to move downward, so that the fixing plate 10 moves to the bottom of the battery to support both sides of the battery and prevent the battery from shaking when it is lifted and moved, thereby improving the stability of the battery when it is lifted.

[0032] As shown Figure 3 and Figure 6 in the figure, at the top end of the side of the electric telescopic column 9 close to the mounting bracket 5, a first telescopic rod 11 is fixedly installed. On one side of the first telescopic rod 11, a limiting block is fixedly installed. On both sides of the limiting block, two limiting grooves are provided. The limiting block is slidably connected to the limiting grooves. The electric telescopic column 9, the fixing plate 10, the first electric push rod 87, and the first telescopic rod 11 are all symmetrically arranged with the center of the connecting plate 86.

[0033] It is connected to the electric telescopic column 9 through the first telescopic rod 11. When the first electric push rod 87 extends to push the electric telescopic column 9 to move, the first telescopic rod 11 drives the limiting block to move along the sliding groove, which is convenient for improving the stability of the electric telescopic column 9 when moving on both sides of the connecting plate 86. When the movable block 85 drives the connecting plate 86 to move into the interior of the fixed block 6, the connecting plate 86 drives the first electric push rod 87 and the electric telescopic column 9 to move, causing the first telescopic rod 11 to contract, so that the electric telescopic column 9 can move to one side of the battery, enabling the movement of the electric telescopic column 9 and the fixed plate 10 to support and fix the battery, further improving the stability of the movement of the electric telescopic column 9. Through the symmetrically arranged electric telescopic columns 9, fixed plates 10, first electric push rods 87 and first telescopic rods 11, it is possible to limit on both sides of the battery and improve the stability during the replacement, installation and movement of the battery.

[0034] As Figure 7 shown, an installation groove is provided on one side of the telescopic end of the electric telescopic column 9. A second electric push rod 12 is fixedly installed inside the installation groove. One end of the second electric push rod 12 is fixedly installed with a pressing plate 13, and one side of the pressing plate 13 is flush with one side of the telescopic end of the electric telescopic column 9.

[0035] When the electric telescopic column 9 extends, the fixed plate 10 moves to the bottom of the battery to support it. At the same time, the telescopic end of the electric telescopic column 9 exposes the pressing plate 13. By starting the second electric push rod 12 to push the pressing plate 13 out of the installation groove, one side of the pressing plate 13 is attached to the outside of the battery, further pressing the battery tightly so that the battery can be kept stable and is convenient for lifting.

[0036] As Figures 4 to 6 shown, a regulating block 14 is rotatably connected to the top of the locking block 7. The top of the regulating block 14 is slidably connected to the bottom of the mounting bracket 5. The locking block 7 and the regulating block 14 are symmetrically arranged at the bottom of the mounting bracket 5.

[0037] The regulating block 14 facilitates the installation of the locking block 7. The driving mechanism 2 causes the locking block 7 to rotate along the bottom of the regulating block 14, so that one end of the locking block 7 rotates to the horizontal direction and its locking opening rotates to the top of the battery. When the mounting bracket 5 drives the regulating block 14 and the locking block 7 to move, the locking block 7 can drive the battery to move upward, removing the battery from the heavy truck, which is convenient for installation and replacement. By driving the locking block 7 to slide along the bottom of the mounting bracket 5 through the regulating block 14, it is convenient to adjust the locking block 7 according to the size of the battery, facilitating adaptation to small-sized batteries, being able to fit with small-sized batteries, improving the adaptability of battery lifting, and further improving the stability during battery lifting.

[0038] As Figures 4 to 6As shown, two sliding grooves are provided at the bottom of the mounting frame 5 and between the adjusting blocks 14. A moving block 15 is fixedly installed on one side of the adjusting block 14. A fixing column 16 is fixedly installed on the top of the moving block 15. A groove is provided at the top of the fixing column 16. A third electric push rod 17 is fixedly installed inside the groove. A slot is provided at the bottom of the movable block 85. One end of the third electric push rod 17 is inserted into the slot.

[0039] When it is necessary to lift small-sized batteries, through the action of the motor 81 driving the rotating rod 82 and the movable plate 83, the rotating plate 84 deflects to drive the movable block 85 to move along the inner wall of the bottom of the fixed block 6 and move towards the rotating rod 82. Through the connection of the third electric push rod 17, when the movable block 85 moves, it drives the third electric push rod 17, the fixing column 16 and the moving block 15 to move, so that the moving block 15 drives the adjusting block 14 and the locking block 7 to move, so that the locking blocks 7 at the bottom of the mounting frame 5 can move closer to each other. After the locking block 7 moves to a suitable position, stop the rotation of the motor 81, so that the movable block 85 no longer moves. Start the third electric push rod 17 to contract and no longer insert into the slot at the bottom of the movable block 85, and fix the position of the locking block 7. When it is necessary to adjust the positions of the electric telescopic column 9 and the fixing plate 10, start the motor 81 to rotate again. Thus, while adjusting the distances between the electric telescopic column 9, the fixing plate 10 and the battery, the distance between the locking blocks 7 can also be adjusted, so that the locking blocks 7 can adapt to small-sized batteries and further improve the stability when the batteries move.

[0040] As Figures 4 to 6 shown, the moving block 15 is located at the bottom of the two sliding grooves, and its top is slidably connected to the bottom of the mounting frame 5. The fixing column 16 passes through the two sliding grooves and extends to the bottom of the movable block 85, and it is slidably connected to the two sliding grooves. The moving block 15, the fixed block 6 and the third electric push rod 17 are symmetrically arranged with respect to the center of the mounting frame 5.

[0041] When the movable block 85 moves, it drives the third electric push rod 17 and the fixing column 16 to move along the sliding groove, and makes the moving block 15 move along the bottom of the mounting frame 5 at the bottom of the sliding groove. Through the symmetrically arranged moving block 15, fixed block 6 and third electric push rod 17, it is convenient to make the locking blocks 7 at both ends of the bottom of the mounting frame 5 move closer to each other at the same time, adjust the distance, and improve the convenience of adjustment.

[0042] As Figures 4 to 6 shown, a telescopic block 18 is fixedly installed on the side of the moving block 15 away from the adjusting block 14. A connecting block 19 is fixedly installed at one end of the telescopic block 18. The top of the connecting block 19 is fixedly installed with the bottom of the mounting frame 5. The connecting block 19 is located between the two sliding grooves, and the telescopic block 18 is located at the bottom of the two sliding grooves.

[0043] The connecting block 19 facilitates the connection between the telescopic block 18 and the mounting bracket 5. The telescopic end of the telescopic block 18 is connected to the moving block 15. When the moving block 15 drives the adjusting block 14 and the moving block 15 to move, the telescopic block 18 contracts, thereby improving the stability of the moving block 15 during movement, facilitating the movement adjustment of the locking block 7, enabling the locking block 7 to fix the small-sized battery, and enhancing the stability during the lifting of the small-sized battery.

[0044] Working principle: During use, the driving mechanism 2 drives the moving assembly 3 to move. Through the connection of the connecting rod 4, the mounting bracket 5 and the locking block 7 are moved to the top of the battery. The driving mechanism 2 causes the locking block 7 to rotate to the horizontal state, with its locking opening rotated to the top of the battery. Then, the driving mechanism 2 is started to make the moving assembly 3 drive the connecting rod 4 and the mounting bracket 5 to move upward. By limiting the top of the battery with the locking block 7, the battery is driven to move upward, and the battery is removed from the heavy truck. Then, the first electric push rod 87 is started to push the electric telescopic column 9 and the fixed block 6 to move. When the electric telescopic column 9 moves, it drives the first telescopic rod 11 and the limiting block to move along the limiting groove, causing the electric telescopic column 9 to drive the fixing plate 10 to move to both ends of the battery. Then, by starting the motor 81, the rotating rod 82 is driven to rotate along the inner wall of the bottom of the fixed block 6. Through the limitation of the two sides of the rotating plate 84 sliding along the inner wall of the fixed block 6, the rotating plate 84 can move upward along the rotating rod 82, so that one end of the rotating plate 84 deflects upward, and the other end drives the movable block 85 to move along the inner wall of the bottom of the fixed block 6 towards the direction close to the rotating rod 82, causing the movable block 85 to drive the connecting plate 86 and the first electric push rod 87 to move into the interior of the fixed block 6 through the movable opening, making the electric telescopic column 9 drive the fixing plate 10 to move towards the mounting bracket 5. When the electric telescopic column 9 approaches both sides of the battery, the electric telescopic column 9 is started to drive the fixing plate 10 to move downward, so that the fixing plate 10 moves to the bottom of the battery and fits with its bottom to support both sides of the battery. When the electric telescopic column 9 extends, the pressing plate 13 is exposed. The second electric push rod 12 is started to push the pressing plate 13 out of the mounting groove, making one side of the pressing plate 13 fit with the outer side of the battery to further press the battery tightly, so that the battery remains stable during lifting. After the battery is supported and limited, the driving mechanism 2 drives the moving assembly 3 to move along the top of the support frame 1, so that the locking block 7 at the bottom of the mounting bracket 5 drives the battery to move and replace the battery.

[0045] When it is necessary to lift a small-sized battery, the driving mechanism 2 is driven to move the moving component 3. Through the connection of the connecting rod 4, the mounting bracket 5 and the locking block 7 are moved to the top of the battery. The motor 81 is started to drive the rotating rod 82 and the movable plate 83, so that the rotating plate 84 deflects to drive the movable block 85 to move along the inner wall of the bottom of the fixed block 6 towards the rotating rod 82. Through the connection of the third electric push rod 17, when the movable block 85 moves, it drives the third electric push rod 17, the fixed column 16 and the moving block 15 to move, so that the moving block 15 drives the adjusting block 14 and the locking block 7 to move, enabling the locking blocks 7 at the bottom of the mounting bracket 5 to move closer to each other. After the locking block 7 moves to a suitable position, the rotation of the motor 81 is stopped, so that the movable block 85 no longer moves. The third electric push rod 17 is started to contract and is no longer inserted into the slot at the bottom of the movable block 85, fixing the position of the locking block 7. When it is necessary to adjust the positions of the electric telescopic column 9 and the fixing plate 10, the motor 81 is started to rotate continuously. Thus, while adjusting the distances between the electric telescopic column 9, the fixing plate 10 and the battery, the distance between the locking blocks 7 can also be adjusted, enabling the locking blocks 7 to adapt to small-sized batteries and facilitating the movement of the batteries.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them.
