[0020] Reference Figure 1-9 A modular replacement trolley for energy storage battery packs includes a vehicle body 1. A support frame 9 is installed at the middle of the top of the vehicle body 1, and a control box 10 is installed at the rear end of the top of the vehicle body 1. Two lifting mechanisms 7 are installed at the front end of the top of the vehicle body 1. Multiple rows of cabinets 2 are installed on both sides of the support frame 9. The cabinets 2 have multiple storage cavities 8 for storing energy storage battery packs. A main track mechanism 5 is installed at the bottom of the outer end of the cabinets 2. A secondary track mechanism 11 is installed on the sides of the two lifting mechanisms 7. The main track mechanism 5 and the secondary track mechanism 11 form a moving track around the cabinets 2. Two feeding trolleys 6 are installed on the outer side of the moving track. A locking mechanism 3 is installed at the bottom of the inside of the storage cavity 8, and a battery pack insertion / removal mechanism 4 is installed at the top of the inside of the storage cavity 8.

[0021] In this invention, multiple rows of cabinets 2 are installed on top of the vehicle body 1. New energy storage battery packs are stored in the storage cavity 8. A main track mechanism 5 is installed on the bottom side of the cabinet 2, and a secondary track mechanism 11, driven by a lifting mechanism 7, is installed at the end of the cabinet 2. When the secondary track mechanism 11 is aligned with the main track mechanism 5 on the side, the main track mechanism 5 and the secondary track mechanism 11 form a moving track around the cabinet 2. An empty feeding trolley 6 can then move to the outside of the corresponding storage cavity 8, and the stored energy storage battery pack is pushed out into the feeding trolley 6 through the battery pack insertion and removal mechanism 4. After the feeding trolley 6 is moved to the front position, it is convenient for workers to operate. After the energy storage battery pack is replaced, the used energy storage battery pack is placed in the feeding trolley 6. With the cooperation of the feeding trolley 6 and the moving track, it moves to the outside of the empty storage cavity 8. The battery pack insertion and removal mechanism 4 inserts the used energy storage battery pack on the feeding trolley 6 into the empty storage cavity 8. At this time, the locking mechanism 3 moves upward to lock the bottom of the inserted used energy storage battery pack, avoiding the risk of the energy storage battery pack falling off during transfer. The process of pulling out and stacking the energy storage battery pack is completed automatically, which effectively reduces the labor intensity of the staff in replacing the energy storage battery pack. Moreover, the automatic collection of used energy storage battery packs reduces the safety of used battery pack recycling.

[0022] As a further embodiment of the present invention, the bottom of the storage cavity 8 is provided with multiple storage rollers 81, and the opening edge of the storage cavity 8 is provided with a positioning groove 82 that cooperates with the feeding trolley 6. An electromagnetic lock 83 is fixedly installed inside the positioning groove 82. The bottom of the storage cavity 8 is provided with an installation groove 84 that cooperates with the locking mechanism 3. In the present invention, the energy storage battery pack is placed inside the storage cavity 8, and the bottom is limited and fixed by the locking mechanism 3 to avoid the risk of falling during the movement process. During the removal and placement of the energy storage battery pack, the locking mechanism 3 moves downward to unlock the bottom first. When the feeding trolley 6 corresponds to the storage cavity 8, it is positioned by the positioning grooves 82 on both sides, and locked and fixed by the electromagnetic lock 83 and the structure on the feeding trolley 6, thereby improving the stability and safety of the energy storage battery pack during the insertion and removal process.

An electronic tag 34 that cooperates with the feeding trolley 6 is provided on the outer side of the locking plate 33. In the present invention, the locking plate 33 moves vertically under the action of the electric telescopic rod 31 and the movable plate 32. When the locking plate 33 is at the uppermost position, it limits and fixes the front end of the energy storage battery pack stored in the storage cavity 8. When the feeding trolley 6 passes by, it scans the information of the electronic tag 34 to determine whether the inside of the storage cavity 8 is empty or the new or old state of the internal energy storage battery pack.

[0024] As a further embodiment of the present invention, the battery pack insertion and removal mechanism 4 includes an insertion and removal bracket 41 installed on the top of the cabinet 2, and two rows of motor and roller-driven chains 42 are installed at the bottom of the insertion and removal bracket 41. The outer surface of the chain 42 is provided with a T-shaped push-pull block 43. In the present invention, when the chain 42 moves, the push-pull block 43 at its bottom contacts the surface of the energy storage battery pack, pulling the energy storage battery pack to move between the storage cavity 8 and the feeding trolley 6, thus completing the transfer operation of the energy storage battery pack.

[0025] As a further embodiment of the present invention, the main track mechanism 5 includes a main track 51, and a main track limiting member 52 is provided at the end of the main track 51.

A conductive sliding guide rail 54 that cooperates with the feeding trolley 6 is provided at the top of the outer side of the main track 51. In the present invention, the main track mechanism 5 is distributed on the side of the cabinet 2. The feeding trolley 6 can reach the corresponding storage cavity 8 along the direction of the main track mechanism 5 to complete the replacement operation of the old and new energy storage battery packs.

[0026] As a further embodiment of the present invention, the secondary track mechanism 11 has the same structure as the main track mechanism 5, and a sensor for mutual sensing is provided at the connection between the main track mechanism 5 and the secondary track mechanism 11. In the present invention, the secondary track mechanism 11 can move up and down under the action of the lifting mechanism 7. When the feeding trolley 6 moves to the secondary track mechanism 11, the lifting mechanism 7 can drive the feeding trolley 6 to move, and then transfer it to the main track mechanism 5 at different heights to complete the picking and placing operation of the energy storage battery pack at different heights, and transfer it to the set height, so as to facilitate the picking and placing of the energy storage battery pack by the staff.

[0027] As a further embodiment of the present invention, the lifting mechanism 7 includes vertically distributed limiting brackets 71, and two guide slide rods 72 are fixedly installed inside the limiting brackets 71. A threaded screw 73 is also rotatably installed inside the limiting brackets 71. A motor 74 that drives the threaded screw 73 is fixedly installed on the top of the limiting brackets 71. A lifting platform 75 connected to the secondary track mechanism 11 is provided between the guide slide rods 72 and the threaded screw 73. A photoelectric sensor 76 corresponding to the feeding trolley 6 is installed on the top of the lifting platform 75. In the present invention, the secondary track mechanism 11 moves up and down under the action of the lifting mechanism 7. When the feeding trolley 6 moves onto the secondary track mechanism 11, it can follow the secondary track mechanism 11 to move up and down and cooperate with the main track mechanism 5 of the corresponding height to complete the movement of the feeding trolley 6 between the cabinets 2 of different heights.

[0028] As a further embodiment of the present invention, the feeding trolley 6 includes a feeding box 61, a transmission assembly is installed at the bottom of the feeding box 61, and positioning assemblies are installed on both sides of the feeding box 61. Multiple feeding wheels 67 are rotatably installed at the bottom of the inner side of the feeding box 61, and a signal receiver that cooperates with the locking mechanism 3 and the lifting mechanism 7 is fixedly installed at the end of the feeding box 61. In the present invention, when the feeding trolley 6 moves to the outside of the corresponding storage cavity 8, the positioning assemblies on both sides are activated, and the ends of the positioning assemblies are inserted into the positioning grooves 82 and fixed in cooperation with the electromagnetic lock 83, which facilitates the rapid transfer of the energy storage battery pack between the storage cavity 8 and the feeding box 61, and the operation is simple and convenient.

[0029] As a further embodiment of the present invention, the transmission assembly includes a transmission bracket 62 installed at the bottom of the feeding box 61, and sliding receivers 63 electrically connected to the main track mechanism 5 and the auxiliary track mechanism 11 are installed on both sides of the top of the transmission bracket 62. Track wheels 64 that roll with the main track mechanism 5 and the auxiliary track mechanism 11 are installed at the front end of the sliding receivers 63. A walking motor 65 that is drivenly connected to the main track mechanism 5 and the auxiliary track mechanism 11 is installed in the middle of the top of the transmission bracket 62. In the present invention, the feeding trolley 6 achieves horizontal movement through the walking motor 65 in the transmission assembly, and the track wheels 64 keep the feeding trolley 6 in a horizontal movement state, thereby improving the stability of the energy storage battery pack during the transfer process.

[0030] As a further embodiment of the present invention, the positioning component includes a rectangular groove 66 disposed on the side of the feeding box 61, and a positioning slide plate 69 installed inside the rectangular groove 66. The side of the feeding box 61 is also equipped with a positioning electric push rod 68 that drives the positioning slide plate 69 to extend and retract. In the present invention, when the feeding trolley 6 moves to the outer side of the receiving cavity 8, the positioning electric push rod 68 drives the positioning slide plate 69 to move outward, and the positioning slide plate 69 is inserted into the positioning groove 82, providing positioning and protection for the transfer of the energy storage battery pack, and improving the stability and safety of the energy storage battery pack transfer process.

[0031] When in use, when the secondary track mechanism 11 is aligned with the main track mechanism 5 on the side, the main track mechanism 5 and the secondary track mechanism 11 form a moving track surrounding the cabinet 2. The empty feeding trolley 6 can then move to the outside of the corresponding storage cavity 8, and the stored energy storage battery pack is pushed into the feeding trolley 6 through the battery pack insertion and removal mechanism 4. After the feeding trolley 6 is moved to the front position, it is easy for the staff to pick it up. After the energy storage battery pack is replaced, the waste energy storage battery pack is placed in the feeding trolley 6. With the cooperation of the feeding trolley 6 and the moving track, it moves to the outside of the empty storage cavity 8. The battery pack insertion and removal mechanism 4 inserts the waste energy storage battery pack on the feeding trolley 6 into the empty storage cavity 8. At this time, the locking mechanism 3 moves upward to lock the bottom of the inserted waste energy storage battery pack, avoiding the risk of the energy storage battery pack falling off during the transfer. The process of pulling out and stacking the energy storage battery pack is completed automatically, effectively reducing the labor intensity of the staff in replacing the energy storage battery pack.
