DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] In order to solve the technical problems of the currently used heavy-duty battery pack transportation and loading mechanism being too heavy, the heavy-duty battery pack transportation and assembly operation efficiency being too low, and the heavy-duty battery pack transportation and assembly operation safety being too low, the present invention provides a heavy-duty battery pack detachable transportation and loading device, which can be used for carrying and loading heavy-duty battery packs and solve the technical problems of being too heavy to be moved and transported, low assembly operation efficiency, and low assembly safety.

[0019] See also Figure 1 , Figure 1 It is a schematic diagram of the three-dimensional structure of a detachable transport and loading device for a heavy-duty battery pack in one embodiment of the present invention. The detachable transport and loading device for a heavy-duty battery pack includes a bearing mechanism 1, a propulsion mechanism 2, a limiting mechanism 3 and a slide rail mechanism 4.

[0020] The bearing mechanism 1 includes a pressure-bearing frame 11 and a protection frame 12. The pressure-bearing frame 11 and the protection frame 12 are detachably fixedly connected. A space for accommodating a battery pack is formed between the pressure-bearing frame 11 and the protection frame 12. In this embodiment, the pressure-bearing frame 11 and the protection frame 12 are locked by slide bolts.

[0021] In some embodiments, please refer to Figure 1 A plurality of lifting rings 121 are fixed on the upper protection frame 12 to facilitate lifting.

[0022] The propulsion mechanism 2 is used to propel the battery pack between the pressure-bearing frame 11 and the protection frame 12 to move.

[0023] In some embodiments, please refer to Figure 2-Figure 5The propulsion mechanism 2 is installed on the pressure frame 11, and the propulsion mechanism 2 includes two front fixing blocks 21, two rear fixing blocks 22, two screw rods 23, two nuts 24, two driving members 25 and a push block 26. The two front fixing blocks 21 and the two rear fixing blocks 22 are respectively fixed to the two ends of the pressure frame 11, and the two ends of the two screw rods 23 are respectively rotatably arranged on the two front fixing blocks 21 and the two rear fixing blocks 22. The two nuts 24 are respectively threadedly sleeved on the screw rods 23. The two driving members 25 are connected to the two screw rods 23 and are used to drive the screw rods 23 to rotate. The two ends of the push block 26 are respectively fixedly connected to the two nuts 24, and the push block 26 is used to be detachably fixedly connected to the battery pack.

[0024] In some embodiments, please refer to Figure 2-Figure 5 The push block 26 is provided with a plurality of first slots 261 , and the first slots 261 are used to connect with the front cross beam of the battery pack.

[0025] In some embodiments, please refer to Figure 2-Figure 5 The driving member 25 includes a fixed housing 251, a first bevel gear, a second bevel gear and a hand wheel 252. The fixed housing 251 is fixed to the pressure frame 11. The first bevel gear and the second bevel gear are both rotatably arranged in the fixed housing 251 and mesh with each other. The first bevel gear is coaxially fixedly connected to the screw rod 23, and the second bevel gear is fixedly connected to the hand wheel 252. When in use, the two hand wheels 252 are synchronously rotated to drive the second bevel gear and the first bevel gear to rotate. The first bevel gear drives the screw rod 23 to rotate. The two screw rods 23 push the push block 26 to move, and the push block 26 pushes the battery pack to move. It should be understood that when the two hand wheels 252 rotate synchronously in opposite directions, the function of pulling the battery pack can also be realized. In this embodiment, by setting the first bevel gear and the second bevel gear, the operating position of the hand wheel 252 can be converted to both sides of the pressure frame 11, thereby expanding the operator's observation field and improving the safety of assembly docking.

[0026] In the present invention, by providing the propulsion mechanism 2, the heavy battery pack can be quickly moved on the transport loading mechanism, the labor intensity of the operator can be reduced, and the assembly and docking efficiency can be improved.

[0027] In some embodiments, please refer to Figure 2-Figure 7 The limiting mechanism 3 is installed on the pressure-bearing frame 11 and is used to fix the battery pack on the pressure-bearing frame 11.

[0028] Specifically, the limiting mechanism 3 includes a plurality of side limiting blocks 31, a head limiting cross bar 32, a tail limiting cross bar 33, a tensioning assembly 34 and a stopper 35. The pressure-bearing frame 11 can be detachably mounted on the pressure-bearing frame 11 and is used to abut against both sides of the battery pack. The head limiting cross bar 32 is slidably arranged on the pressure-bearing frame 11 and is used to be connected to one end of the battery pack. The tail limiting cross bar 33 is arranged on the pressure-bearing frame 11 and is used to be connected to the other end of the battery pack. The tensioning assembly 34 is used to press the head limiting cross bar 32. A wedge block 331 is welded on the tail limiting cross bar 33. The stopper 35 is fixed to the pressure-bearing frame 11. A wedge groove matching the wedge block 331 is opened on the stopper 35.

[0029] Specifically, the tensioning assembly 34 includes a base 341 and a pushing screw 342. The base 341 is fixed to the pressure-bearing frame 11. A screw hole is opened on the base 341. The pushing screw 342 is threadedly connected to the screw hole. One end of the pushing screw 342 is used to abut against the head limiting cross bar 32.

[0030] Preferably, the tensioning assembly 34 further includes a cushion block 343 , which is fixed to one end of the pushing screw 342 and is used to abut against the head limiting cross bar 32 .

[0031] When in use, after the heavy-duty battery pack is placed in, the head limiting cross bar 32 and the tail limiting cross bar 33 are respectively connected to the front and rear cross beams of the heavy-duty battery pack by means of the card slot structure, the wedge block 331 of the tail limiting cross bar 33 is inserted into the wedge slot, and the pushing screw 342 is rotated to press and lock the head limiting cross bar 32 through the thrust of the pushing screw 342; when the battery pack needs to be pushed out, the pushing screw 342 is first rotated in the opposite direction to slightly loosen the wedge block 331 of the battery pack and the tail limiting cross bar 33 from the wedge slot, and then the head limiting cross bar 32 and the tail limiting cross bar 33 are removed, and finally the battery pack is pushed out through the propulsion mechanism 2.

[0032] Preferably, a first fixing groove is formed on the side limit block 31 , and a second fixing groove is formed on the pressure frame 11 . The first fixing groove and the second fixing groove are connected by bolts to achieve detachable connection of the side limit block 31 to the pressure frame 11 .

[0033] Preferably, guide wheels 36 are fixed at both ends of the tail limit cross bar 33. At the same time, the limit structure can be modularly replaced according to different working conditions. In the scenario where rapid docking and limiting are required to achieve transportation and loading, the guide wheel 36 can be replaced with an automatic hook (such as a Jane hook). The automatic hook is installed on the block 35 by screws, and then the corresponding hook on the heavy-duty battery pack is pushed to achieve rapid docking and locking of the heavy-duty battery pack and the loading mechanism.

[0034] like Figure 4 As shown, the slide rail mechanism 4 is arranged on the pressure-bearing frame 11, and the slide rail mechanism 4 is used to place the battery pack.

[0035] Specifically, the slide rail mechanism 4 includes a bottom guide rail 41 and a side guide rail 42. The bottom guide rail 41 is installed on the pressure-bearing frame 11, and a plurality of bottom rollers 411 are rotatably connected to the bottom guide rail 41. The bottom rollers 411 are used to place battery packs. The side guide rails 42 are installed on the pressure-bearing frame 11, and a plurality of side rollers 421 are rotatably connected to the side guide rails 42. The side rollers 421 are used to abut against the side walls of the battery packs.

[0036] By setting a plurality of bottom rollers 411, the weight of the heavy battery pack can be evenly shared while ensuring that the heavy battery pack can move quickly. By setting the side rollers 421, the direction of movement of the heavy battery pack can be limited and the stability of movement can be improved. The roller structure can greatly reduce movement resistance and improve assembly and debugging efficiency.

[0037] The beneficial effects of the technical solution proposed by the present invention include: (1) The slide rail mechanism 4 carries the heavy battery pack, which is connected to the heavy battery pack through the propulsion mechanism 2 to achieve movement. The heavy battery pack is fixed to the pressure frame 11 through the limit mechanism 3, and the pressure frame 11 is connected and fixed to the protection frame 12 for transportation and hoisting. The bearing mechanism 1 can realize the separation of the upper and lower parts, which is convenient for assembly and transportation and hoisting. The optimized bearing mechanism 1 greatly reduces the dead weight of the transportation and loading mechanism; the limit mechanism 3 realizes the complete fixation of the heavy battery pack on the bearing mechanism 1 through the side limit block 31, the head limit cross bar 32, and the tail limit cross bar 33, thereby improving the safety of transportation and movement. At the same time, the limit mechanism 3 can be directly and quickly disassembled after use, which increases the assembly and debugging operation space and improves the assembly operation efficiency; (2) The propulsion mechanism 2 can realize the movement of the heavy battery pack through the screw nut, and the bevel gear steering can realize the operator's larger observation field and safer operating position, thereby reducing the labor intensity of the operator; (3) The slide rail device uses multiple rollers to achieve the pressure-bearing and moving work of the heavy battery pack, ensuring that the heavy battery pack can be easily moved on the transport loading mechanism and improving the docking and assembly efficiency; the supporting frame adopts welding technology, and most of the other mechanisms adopt a slot design, avoiding the risk of foreign matter falling into the battery pack caused by operations such as screw removal.

[0038] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
