DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] The present invention provides a battery lifting mechanism for a heavy truck swap station, such as Figures 1 to 3 As shown, it includes a support frame 1, and a lifting mechanism is provided at one end of the support frame 1; The lifting mechanism includes a driving mechanism 2, a moving component 3, a connecting rod 4, a mounting frame 5, a fixed block 6, a locking block 7, an adjusting component 8, an electric telescopic column 9, and a fixing plate 10. The driving mechanism 2 is located at the top of one end of the support frame 1, and the moving component 3 is arranged at the bottom of the driving mechanism 2. The connecting rod 4 is fixedly installed at the bottom of the moving component 3, and a mounting frame 5 is arranged at the bottom of the connecting rod 4. A fixed block 6 is fixedly installed in the middle of the top of the mounting frame 5, and the fixed block 6 and the top of the mounting frame 5 are both fixedly installed with the connecting rod 4. An adjusting component 8 is arranged inside the fixed block 6, and a locking block 7 is arranged at the bottom of the mounting frame 5. Electric telescopic columns 9 are arranged on both sides of the mounting frame 5 and the adjusting component 8, and a fixed plate 10 is fixedly installed at the bottom of the electric telescopic column 9.

[0018] The driving mechanism 2 drives the moving component 3, the connecting rod 4 and one end of the mounting frame 5 to the top of the battery, and locks the battery with the locking block 7. The supporting frame 1 facilitates the driving mechanism 2 to drive the moving component 3, the connecting rod 4 and the mounting frame 5 to move back and forth, so as to facilitate the replacement and installation of the battery. The adjusting component 8 is installed 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 move the electric telescopic column 9 and the fixing plate 10, so that the electric telescopic column 9 and the fixing plate 10 move to the side close to the battery, and 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 the two sides of the battery, improve the stability of the battery during lifting, and prevent the driving mechanism 2 and the moving component 3 from changing too fast in speed during starting, stopping or running during the lifting process to generate vibration, so that the battery will shake accordingly, affecting the stability of the battery lifting, and it is not convenient to improve the efficiency of battery replacement.

[0019] like Figures 3 to 6 As shown, the adjustment 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; The output end of the motor 81 is transmission-connected with a rotating rod 82, and 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 with a movable plate 83, and 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 with rotating plates 84, and one end of the rotating plate 84 is hinged with a 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, and one end of the movable block 85 is fixedly installed with a connecting plate 86. The first electric push rod 87 is fixedly installed on both sides of the bottom of one end of the connecting plate 86 away from the fixed block 6. Both sides of the fixed block 6 are provided with movable openings, 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 with the inner wall of the bottom of the fixed block 6, and one end thereof passes through the movable opening and extends to both sides of the mounting frame 5, and one end of the first electric push rod 87 is fixedly installed with the electric telescopic column 9.

[0020] After the battery of the heavy truck is taken out and moved to the top of the heavy truck, the first electric push rod 87 is started to push the electric telescopic column 9 and the fixed plate 10 to move to the two ends of the battery, and then the starting motor 81 drives the rotating rod 82 to rotate along the inner wall of the bottom of the fixed block 6. Through the limitation that the two 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, and then the movable block 85 drives the connecting plate 86 and the first electric push rod 87 to move toward the inside of the fixed block 6 through the movable opening, so that the electric telescopic column 9 drives the fixed plate 10 to move toward the direction of the mounting frame 5. When the electric telescopic column 9 is close to the two sides of the battery, the electric telescopic column 9 is started to drive the fixed plate 10 to move downward, so that the fixed plate 10 moves to the bottom of the battery, supports the two sides of the battery, prevents the battery from shaking when it is lifted and moved, and thus improves the stability of the battery when it is lifted.

[0021] like Figure 3 , Figure 6 As shown, a first telescopic rod 11 is fixedly installed on the top of the electric telescopic column 9 close to the mounting frame 5, and a limiting block is fixedly installed on one side of the first telescopic rod 11. Two limiting grooves are provided on both sides of the limiting block. The limiting block is slidably connected to the limiting grooves. The electric telescopic column 9, the fixed plate 10, the first electric push rod 87 and the first telescopic rod 11 are all symmetrically arranged with the connecting plate 86 as the center.

[0022] The first telescopic rod 11 is connected to the electric telescopic column 9. When the first electric push rod 87 is extended to push the electric telescopic column 9 to move, the first telescopic rod 11 drives the limiting block to move along the slide groove, which is convenient for improving the stability of the electric telescopic column 9 when it moves on both sides of the connecting plate 86. When the movable block 85 drives the connecting plate 86 to move toward the inside of the fixed block 6, the connecting plate 86 drives the first electric push rod 87 and the electric telescopic column 9 to move, so that the first telescopic rod 11 contracts, thereby facilitating the electric telescopic column 9 to move to one side of the battery, so that the movement of the electric telescopic column 9 and the fixed plate 10 supports and fixes the battery, further improving the stability of the movement of the electric telescopic column 9. The symmetrically arranged electric telescopic column 9, the fixed plate 10, the first electric push rod 87 and the first telescopic rod 11 can be limited on both sides of the battery, and the stability of the battery during replacement and installation movement is achieved.

[0023] like Figure 7 As shown, a mounting 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 mounting groove, a clamping plate 13 is fixedly installed on one end of the second electric push rod 12, and one side of the clamping plate 13 is flush with one side of the telescopic end of the electric telescopic column 9.

[0024] When the electric telescopic column 9 is extended, the fixing 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 clamping plate 13. By starting the second electric push rod 12, the clamping plate 13 is pushed out of the installation groove, so that one side of the clamping plate 13 is in contact with the outside of the battery, further clamping the battery, so that the battery can remain stable and is easy to lift.

[0025] like Figures 4 to 6 As shown, the top of the locking block 7 is rotatably connected to the adjusting block 14 , the top of the adjusting block 14 is slidably connected to the bottom of the mounting frame 5 , and the locking block 7 and the adjusting block 14 are symmetrically arranged at the bottom of the mounting frame 5 .

[0026] The locking block 7 is conveniently installed by the adjusting block 14, and the driving mechanism 2 makes the locking block 7 rotate along the bottom of the adjusting block 14, so that one end of the locking block 7 rotates to the horizontal direction, and the locking mouth rotates to the top of the battery. When the mounting frame 5 drives the adjusting block 14 and the locking block 7 to move, the locking block 7 can drive the battery to move upward, and the battery can be removed from the heavy truck for easy installation and replacement. The locking block 7 and the bottom of the mounting frame 5 are driven to slide by the adjusting block 14, so that the locking block 7 can be adjusted according to the size of the battery, so as to adapt to small-sized batteries and fit with small-sized batteries, thereby improving the adaptability of battery lifting and further improving the stability of the battery during lifting.

[0027] like Figures 4 to 6As shown, two slide 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 on 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, and one end of the third electric push rod 17 is plugged into the slot.

[0028] When it is necessary to lift a small-sized battery, the motor 81 drives the rotating rod 82 and the movable plate 83, so that the rotating plate 84 deflects and drives the movable block 85 to move along the inner wall at the bottom of the fixed block 6 and move toward 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 movable block 15 to move, so that the movable block 15 drives the adjustment block 14 and the locking block 7 to move, so that the locking block 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, the rotation of the motor 81 is stopped, so that the movable block 85 no longer moves, and the third electric push rod 17 is started to shrink and no longer plug into the slot at the bottom of the movable block 85, so that the position of the locking block 7 is fixed. When it is necessary to adjust the position of the electric telescopic column 9 and the fixed plate 10, the motor 81 is started again to rotate, so that while adjusting the distance between the electric telescopic column 9, the fixed plate 10 and the battery, the distance between the locking blocks 7 can also be adjusted, so that the locking block 7 can adapt to small-sized batteries, further improving the stability of the battery when moving.

[0029] like Figures 4 to 6 As shown, the moving block 15 is located at the bottom of the two slide grooves, and its top is slidably connected to the bottom of the mounting frame 5, the fixed column 16 extends through the two slide grooves to the bottom of the movable block 85, and is slidably connected to the two slide grooves, and the moving block 15, the fixed block 6 and the third electric push rod 17 are symmetrically arranged with the center of the mounting frame 5.

[0030] When the movable block 85 moves, it drives the third electric push rod 17 and the fixed column 16 to move along the slide groove, and makes the movable block 15 move along the bottom of the mounting frame 5 at the bottom of the slide groove. The symmetrically arranged movable block 15, fixed block 6 and third electric push rod 17 facilitate the locking blocks 7 at both ends of the bottom of the mounting frame 5 to move closer to each other at the same time, adjust the distance, and improve the convenience of adjustment.

[0031] like Figures 4 to 6 As 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 on 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 slide grooves, and the telescopic block 18 is located at the bottom of the two slide grooves.

[0032] The telescopic block 18 is conveniently connected to the mounting frame 5 through the connecting block 19, and is connected to the moving block 15 through one side of the telescopic end of the telescopic block 18. 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 and adjustment of the locking block 7, so that the locking block 7 can fix the small-sized battery and improve the stability during the small-sized lifting.

[0033] Working principle: When in use, the driving mechanism 2 drives the moving component 3 to move, and the mounting frame 5 and the locking block 7 are connected by the connecting rod 4 to move to the top of the battery. The driving mechanism 2 rotates the locking block 7 to a horizontal state, so that its lock mouth rotates to the top of the battery, and then the driving mechanism 2 is started to make the moving component 3 drive the connecting rod 4 and the mounting frame 5 to move upward, and the battery is driven to move upward through the restriction of the locking block 7 and the top of the battery, and the battery is removed from the heavy truck, and 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, so that the electric telescopic column 9 drives the fixed plate 10 to move to both ends of the battery, and then the starting motor 81 drives the rotating rod 82 to rotate along the bottom inner wall of the fixed block 6. Through the restriction 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. 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, so that the movable block 85 drives the connecting plate 86 and the first electric push rod 87 to move toward the inside of the fixed block 6 through the movable opening, so that the electric telescopic column 9 drives the fixed plate 10 to move toward the direction of the mounting frame 5. When the electric telescopic column 9 is close to both sides of the battery, the electric telescopic column 9 is started to drive the fixed plate 10 to move downward, so that the fixed 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 is extended, the clamping plate 13 is exposed, and the second electric push rod 12 is started to push the clamping plate 13 out of the mounting groove, so that one side of the clamping plate 13 fits with the outer side of the battery, further clamping the battery, so that the battery remains stable when lifted. After the battery is supported and limited, the driving mechanism 2 drives the movable component 3 to move along the top of the support frame 1, so that the locking block 7 at the bottom of the mounting frame 5 drives the battery to move, and the battery is replaced.

[0034] When it is necessary to lift a small-sized battery, the moving assembly 3 is driven to move by the driving mechanism 2, and the mounting frame 5 and the locking block 7 are connected by the connecting rod 4 to move to the top of the battery. The starting motor 81 drives the rotating rod 82 and the movable plate 83, so that the rotating plate 84 deflects and drives the movable block 85 to move along the bottom inner wall of the fixed block 6 toward 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 and 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, so that the mounting frame 5 The locking blocks 7 at the bottom can move closer to each other. When the locking blocks 7 move to a suitable position, the rotation of the motor 81 is stopped, so that the movable block 85 no longer moves, and the third electric push rod 17 is started to contract and no longer plugged into the slot at the bottom of the movable block 85, so that the position of the locking block 7 is fixed. When it is necessary to adjust the position of the electric telescopic column 9 and the fixed plate 10, the motor 81 is started again to rotate, so that the distance between the locking blocks 7 can be adjusted while adjusting the distance between the electric telescopic column 9, the fixed plate 10 and the battery, so that the locking block 7 can adapt to small-sized batteries and facilitate the movement of the batteries.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
