[0030] During use, the battery pack 3 can be moved by the handle 7, which facilitates its movement and allows its bottom end to be inserted into the interior of the installation box 1. The installation box 1 is compatible with the tram and is fixedly installed with the bottom end of the jumper component 2 and the tram wiring harness. When the battery pack 3 is inserted into the installation box 1, the jumper component 2 at the bottom end can be docked, and then the rotating drive component 4 drives the moving component 5 engaged on its surface to move. When the moving component 5 moves, it can drive the limiting component 6 fixed at its bottom end to move, thereby completing the limiting fixation and completing the installation of the battery pack 3, which is more convenient.

[0031] The utility model can move the battery pack 3 through the handle 7, so that it can be inserted into the installation box 1 of the tram, and fixedly installed with the bottom end of the jumper component 2 and the tram wiring harness. Then, the driving component 4 is rotated to drive the moving component 5 engaged with its surface to move. When the moving component 5 moves, it can drive the limiting component 6 fixed at its bottom end to move, thereby completing the limiting fixation and completing the installation of the battery pack 3. The process is relatively simple, thereby improving the installation efficiency between the battery pack 3 and the tram.

[0032] In one embodiment, for the above-mentioned jumper assembly 2, the jumper assembly 2 includes a connecting seat 201 and a socket seat 202. The outer surface of the connecting seat 201 is fixedly installed with the interior of the installation box 1. The bottom end of the connecting seat 201 is fixedly installed with a jumper plate 203. The top end of the socket seat 202 is fixedly connected to the interior of the battery pack 3. The interior of the socket seat 202 is socketed with the outer surface of the connecting seat 201.

[0033] The battery pack 3 is lifted and moved by the handle 7. Since the top of the socket 202 is fixedly connected to the inside of the battery pack 3, when the battery pack 3 enters the interior of the installation box 1, its inside can be socketed on the outer surface of the connecting socket 201, thereby completing the electrical connection, which is relatively convenient.

[0034] In one embodiment, for the above-mentioned driving component 4, the driving component 4 includes a rotating rod 401, the outer surface of the rotating rod 401 is arranged to rotate internally with the battery pack 3, the top of the rotating rod 401 is fixedly connected to a rotating handle 402, and one end of the rotating rod 401 is fixedly installed with a gear 403, and the surface of the gear 403 is engaged with the surface of the moving component 5.

[0035] By rotating the handle 402, the rotating rod 401 fixedly connected to its bottom end is driven to rotate. When the rotating rod 401 rotates, it can drive the gear 403 fixedly installed on its outer surface to rotate. When the gear 403 rotates, it can drive the moving component 5 meshing with its surface to move, thereby providing stable power for the moving component 5.

[0036] In one embodiment, for the above-mentioned moving component 5, the moving component 5 includes a sliding rod 501, both ends of which are fixedly connected to the interior of the battery pack 3, and a rack 502 is slidably provided on the outer surface of the sliding rod 501, and the surface of the rack 502 is engaged with the surface of the gear 403.

[0037] When the gear 403 rotates with the rotation of the rotating rod 401, it can drive the rack 502 meshed on its surface to move. Since the rack 502 and the sliding rod 501 are each provided with two groups and are symmetrical, when the gear 403 rotates, it can drive the two groups of racks 502 meshed on its surface to move relative to each other and move along the direction of the sliding rod 501, thereby improving the stability of the rack 502 during movement.

[0038] In one embodiment, for the above-mentioned limiting assembly 6, the limiting assembly 6 includes a wedge block 601, the top end of the wedge block 601 is fixedly installed with the bottom end of the rack 502, and the outer surface of the wedge block 601 is sleeved with a fixing cylinder 602, and one side of the fixing cylinder 602 is fixedly installed with the inner wall of the installation box 1.

[0039] When the rack 502 moves with the rotation of the gear 403, it can drive the wedge block 601 fixed at its bottom end to move. When the wedge block 601 moves, one end of it can be inserted into the interior of the fixed cylinder 602, thereby limiting the position of the wedge block 601 and fixing the battery pack 3.

[0041] When the rack 502 moves with the rotation of the gear 403, it can drive the limit block 9 fixed on one side thereof to move. Since the outer surface of the limit block 9 is set to slide internally with the limit groove 8, when the limit block 9 moves, it can move along the direction of the limit groove 8, thereby limiting the moving direction of the rack 502, thereby improving the stability of the rack 502 during movement.

[0042] In one embodiment, for the battery pack 3 , a mounting slot 10 is provided on the top of the battery pack 3 , and a connection switch 11 is fixedly installed inside the mounting slot 10 .

[0043] The setting of the connection switch 11 can disconnect or connect the circuit inside the battery pack 3, thereby preventing the battery pack 3 from generating arcs during installation, thereby improving the safety of the battery pack 3 during installation.

[0044] In summary, with the aid of the above-mentioned technical solution of the present invention, the battery pack 3 can be moved by the handle 7, thereby facilitating its movement and allowing its bottom end to be inserted into the interior of the installation box 1. Since the top of the socket 202 is fixedly connected to the interior of the battery pack 3, when the battery pack 3 enters the interior of the installation box 1, its interior can be socketed on the outer surface of the connecting seat 201, thereby completing the electrical docking. By rotating the handle 402, the rotating rod 401 fixedly connected to its bottom end is driven to rotate. When the rotating rod 401 rotates, it can drive the gear 403 fixedly installed on its outer surface to rotate. When the gear 403 rotates, it can drive the two sets of racks 502 meshed on its surface to move relative to each other. When the rack 502 moves, it can drive the wedge block 601 fixedly installed at its bottom end to move. When the wedge block 601 moves, one end of it can be inserted into the interior of the fixed cylinder 602, thereby limiting the position of the wedge block 601, thereby fixing the battery pack 3.

[0045] Through the above technical solution, 1. The battery pack 3 can be moved by the handle 7 so that it can be inserted into the installation box 1 of the tram, and the bottom end of the jumper component 2 is fixedly installed with the tram wiring harness. Then, the driving component 4 is rotated to drive the moving component 5 engaged with its surface to move. When the moving component 5 moves, it can drive the limiting component 6 fixed at its bottom end to move, thereby completing the limiting fixation and completing the installation of the battery pack 3. The process is relatively simple, thereby improving the installation efficiency between the battery pack 3 and the tram.

[0046] 2. The gear 403 drives the rack 502 to move, which drives the wedge block 601 to move. When the wedge block 601 moves, one end of the wedge block 601 can be inserted into the interior of the fixing tube 602, thereby limiting the position of the wedge block 601, thereby fixing the battery pack 3, and facilitating the installation and fixation of the battery pack 3.
