DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the battery pack disassembly and assembly tool provided by the present invention is described in detail below in conjunction with the accompanying drawings.

[0029] Energy storage container is a highly integrated energy storage device. In the prior art, each energy storage container is provided with multiple battery compartments, each of which is provided with a battery module. Each battery module includes a battery bracket and multiple battery packs. Each battery bracket is provided with multiple compartments for placing battery packs from top to bottom. Each battery pack is located in a corresponding compartment and is fixedly connected to the battery bracket. Therefore, energy storage container has high integration,

[0030] Its small footprint and good scalability make it an important component of the development of distributed energy, smart grids, and energy Internet in energy storage systems.

[0031] Each battery compartment is provided with a hatch, and the battery pack in the battery compartment can be installed or removed by opening the hatch. Take the installation of the battery pack as an example: to push the battery pack into the battery bracket, you need to first put the battery pack on the tooling, and install the tooling on the fork of the forklift, then control the forklift to move to the hatch position, adjust the height of the tooling, so that the tooling corresponds to the battery pack assembly position on the battery bracket, and push the battery pack into the assembly position on the battery bracket through the push-pull rod on the tooling.

[0032] In the existing assembly method, since the weight of the battery pack itself is between 300 and 500 kg, when installing or removing the battery pack at a higher position, the tooling needs to be placed on a forklift first, and then the tooling is raised to the same height as the assembly position by the forklift, and finally the battery pack is installed at the assembly position or removed from the battery bracket by the tooling. With the development of the new energy industry, the total energy storage requirements for energy storage containers are getting higher and higher, that is, a single energy storage container needs to load as many battery packs as possible, so the space for the battery pack in the container is getting smaller and smaller, which will result in higher and higher precision requirements for the operation when placing the battery pack on the battery bracket or removing it from the battery bracket.

[0033] However, the existing battery pack installation and removal process is mainly manual, supplemented by simple roller pallets and forklifts, which is time-consuming and labor-intensive, and poses safety hazards. Moreover, in the production and manufacturing of energy storage containers, battery packs need to be frequently disassembled and assembled. Therefore, the forklift lifting method not only has poor accuracy, but also low efficiency, which seriously affects the production rhythm.

[0034] Therefore, in order to solve the above problems, Figure 1 As shown, the utility model discloses a battery pack disassembly and assembly tool, which is used to install the battery pack 100 on the battery bracket or remove the battery pack 100 from the battery bracket. The battery pack disassembly and assembly tool includes: a disassembly and assembly mechanism 10, a bracket 20 and a lifting mechanism 30. The disassembly and assembly mechanism 10 is used to change the position of the battery pack 100 in the horizontal direction; the bracket 20 is used to be supported on the supporting surface 200, and the disassembly and assembly mechanism 10 is connected to the bracket 20 in a liftable manner; the lifting mechanism 30 is arranged on the bracket 20, and the lifting mechanism 30 is drivingly connected to the disassembly and assembly mechanism 10, and the lifting mechanism 30 is used to drive the disassembly and assembly mechanism 10 to lift and lower, so as to change the position of the battery pack 100 in the vertical direction.

[0035] When assembling the battery pack 100, after the bracket 20 is moved to the position of the hatch of the battery compartment, the battery pack 100 is first placed on the disassembly and assembly mechanism 10, and then the disassembly and assembly mechanism 10 is driven to rise by the lifting mechanism 30, thereby changing the vertical position of the battery pack 100, and after the battery pack 100 is moved to the same height as the battery bracket 20, the battery pack 100 is moved horizontally by the disassembly and assembly mechanism 10, and the battery pack 100 is sent to the battery bracket 20 to complete the assembly. When disassembling the battery pack 100, the disassembly and assembly mechanism 10 can be first raised to the same height as the battery pack 100 to be disassembled by the lifting mechanism 30, and then the battery pack 100 is disassembled from the battery bracket 20 by the disassembly and assembly mechanism 10, and finally, the disassembly and assembly mechanism 10 is lowered by the lifting mechanism 30 to reduce the height of the battery pack 100, so that the battery pack 100 can be replaced later.

[0036] The battery pack disassembly and assembly tool of the present invention is provided with a lifting mechanism 30 on the bracket 20, and the lifting mechanism 30 can drive the disassembly and assembly mechanism 10 to rise and fall, thereby changing the height of the battery pack 100. Compared with the prior art, it is no longer necessary to place the disassembly and assembly mechanism 10 on a forklift, which simplifies the operation steps and improves the efficiency of installing and disassembling the battery pack 100.

[0037] like Figure 1 As shown, in order to facilitate the movement of the bracket 20, a roller 60 is provided at the bottom of the bracket 20, and four rollers 60 are distributed in a matrix. By providing four rollers 60, the stability of the bracket 20 can be improved, and it is less likely to deviate or tilt during movement.

[0038] In this embodiment, the first horizontal direction is the x-axis direction, the second horizontal direction is the y-axis direction, the vertical direction is the z-axis direction, and the x-axis, y-axis and z-axis are perpendicular to each other. That is to say, the four rollers 60 are arranged in pairs, divided into two groups in the x-axis direction, and the two groups of rollers 60 are arranged at intervals in the x-axis direction, and the two groups of rollers 60 are respectively connected to positions close to the two ends of the bracket 20 in the x-axis direction, and the same group of rollers 60 are arranged at intervals in the y-axis direction and connected to the two sides of the bracket 20 in the y-axis direction, thereby forming a matrix distribution.

[0039] It can be understood that in this example, the bracket 20 can be driven to move by external force, but this is not restrictive. In some other embodiments not shown in the figure, a steering structure, a motor and a control device can be set to enable the battery pack disassembly and assembly tool to move automatically according to instructions to further improve work efficiency.

[0040] It should be noted that the lifting mechanism 30 can be a telescopic rod, a screw, a pulley mechanism or the like. As long as the structure can lift the assembly and disassembly mechanism 10, it is within the protection scope of the present utility model.

[0041] For example, Figure 1 and Figure 2 In this embodiment, the lifting mechanism 30 includes: a plurality of lifting units 31 and a driving unit 32. The plurality of lifting units 31 are connected to the bracket 20, all the lifting units 31 are arranged at intervals along the first horizontal direction, and all the lifting units 31 are connected to the disassembly and assembly mechanism 10; the driving unit 32 is respectively connected to each lifting unit 31, and the driving unit 32 is used to drive all the lifting units 31 to rise and fall synchronously.

[0042] In this embodiment, by arranging multiple lifting units 31 at intervals along the first horizontal direction, that is, arranging them at intervals along the x-axis direction, the multiple lifting units 31 form multiple connection positions with the disassembly and assembly mechanism 10 along the x-axis direction. Since the driving unit 32 is respectively connected to each lifting unit 31 and synchronously drives all the lifting units 31 to rise and fall synchronously, under the drive of the driving unit 32, the multiple lifting units 31 can simultaneously raise or lower the disassembly and assembly mechanism 10 at multiple positions in the x-axis direction, so that the disassembly and assembly mechanism 10 as a whole rises or falls synchronously, and the problem of a larger lifting range at one end and a smaller lifting range at the other end will not occur, thereby ensuring the stability of the lifting and lowering of the disassembly and assembly mechanism 10.

[0043] It should be noted that, in the present embodiment, there is only one driving unit 32, and the driving unit 32 is simultaneously connected to multiple lifting units 31, thereby realizing synchronous driving. However, this is not restrictive. In some other embodiments not shown in the figure, there can be multiple driving units 32, each driving unit 32 is connected to a lifting unit 31, each driving unit 32 is connected to a lifting unit 31, and the driving units 32 are opened or closed synchronously, thereby realizing synchronous lifting between the lifting units 31. Without violating the principle and inventive concept of the utility model, the above situations are all within the protection scope of the utility model.

[0044] For example, Figure 1 As shown, the lifting unit 31 includes: a plurality of screw rods 311 and a plurality of connecting members 312. The plurality of screw rods 311 are rotatably connected to the bracket 20 along the vertical direction, and all the screw rods 311 are arranged at intervals along the second horizontal direction perpendicular to the first horizontal direction, wherein at least one screw rod 311 is drivingly connected to the driving unit 32; the plurality of connecting members 312 are arranged one by one corresponding to the screw rods 311, the connecting members 312 are threadedly connected to the corresponding screw rods 311, the connecting members 312 are connected to the disassembly and assembly mechanism 10, and the screw rods 311 drive the connecting members 312 to rise and fall by rotating, thereby driving the disassembly and assembly mechanism 10 to rise and fall.

[0045] For example, Figures 1 to 3As shown, in this embodiment, each lifting unit 31 includes two screw rods 311 and two connecting members 312. For easy distinction, the two screw rods 311 are respectively a first screw rod 3111 and a second screw rod 3112, the top ends of the first screw rod 3111 and the second screw rod 3112 both pass through the top of the bracket 20, and the bottom ends of the first screw rod 3111 and the second screw rod 3112 are rotatably connected to the bottom of the bracket 20. The first screw rod 3111 and the second screw rod 3112 in the same lifting unit 31 are arranged in parallel, and the first screw rod 3111 and the second screw rod 3112 are arranged at intervals in the direction of the y-axis. A connecting piece 312 is arranged on each of the first screw rod 3111 and the second screw rod 3112, and a screw hole is arranged on the connecting piece 312. The first screw rod 3111 and the second screw rod 3112 are both located in the screw hole of the corresponding connecting piece 312 and cooperate with the thread in the screw hole. The first screw rod 3111 and the second screw rod 3112 rotate relative to their respective corresponding connecting pieces 312, thereby driving the corresponding connecting pieces 312 to rise and fall. Figure 4 As shown, the connecting member 312 is fixedly connected to the disassembling and assembling mechanism 10. When the first screw 3111 and the second screw 3112 drive the connecting member 312 to rise and fall by rotating, the connecting member 312 drives the disassembling and assembling mechanism 10 to rise and fall synchronously.

[0046] The lifting unit 31 of the utility model adopts a screw rod 311 and a connecting piece 312 to form a threaded fit between the screw rod 311 and the connecting piece 312, and drives the disassembly and assembly mechanism 10 to rise and fall through the threaded fit. Compared with the method of using a forklift, the threaded fit lifting method is more precise, and the control of the lifting height is more precise.

[0047] In this embodiment, there are two groups of lifting units 31, four screw rods 311 in total, so that the four screw rods rotate simultaneously, so that the disassembly and assembly mechanism 10 can be stably lifted and lowered. However, this is not restrictive, and in some other embodiments not shown in the figure, each group of lifting units 31 can be a screw rod 311, or one group of lifting units 31 is a screw rod 311, and the other group of lifting units 31 is two screw rods 311, etc., without violating the principle and inventive concept of the utility model, the above situations are all within the protection scope of the utility model.

[0048] like Figure 3 As shown, in this embodiment, the lifting unit 31 also includes: a first transmission shaft 313, the first transmission shaft 313 is arranged along the second horizontal direction, and the first transmission shaft 313 is driven and connected between two adjacent screws 311, and the two adjacent screws 311 rotate synchronously through the first transmission shaft 313, so that the screw 311 drivingly connected to the driving unit 32 drives the screw 311 not drivingly connected to the driving unit 32 to rotate synchronously.

[0049] Illustratively, in this embodiment, the first transmission shaft 313 is rotatably arranged between the first screw 3111 and the second screw 3112 along the y-axis direction, and the two ends of the first transmission shaft 313 are respectively driven and cooperated with the first screw 3111 and the second screw 3112, so as to realize the synchronous rotation between the first screw 3111 and the second screw 3112, wherein the first screw 3111 is drivingly connected to the driving unit 32, and the first screw 3111 drives the second screw 3112 to rotate through the first transmission shaft 313, thereby improving the efficiency of mechanical transmission.

[0050] In this embodiment, the rotation axis of the screw rod 311 is arranged along the z-axis direction, and the rotation axis of the first transmission shaft 313 is arranged along the y-axis. Therefore, the screw rod 311 and the first transmission shaft 313 are driven and matched through a commutator.

[0051] It can be understood that the commutator includes: a housing and a plurality of bevel gears arranged in the housing. The bevel gears are rotatably connected in the housing, and, depending on the situation, bevel gears with different rotation axes can be arranged in the housing, and the bevel gears with different rotation axes can be meshed with each other to change the transmission direction. Among them, there can be at least two bevel gears and at most six bevel gears. The following is a specific description of the commutator principle for different usage situations in combination with specific embodiments, wherein the rotation axis of the first gear is in the z-axis direction, the rotation axis of the second gear is in the y-axis direction, and the rotation axis of the third gear is in the x-axis direction.

[0052] Combination Figure 1 In the embodiment shown, the first screw 3111 and the first transmission shaft 313 are driven together through the first commutator 314. The first commutator 314 has two bevel gears inside, namely the first gear and the second gear, wherein the first gear whose rotation axis is in the z-axis direction is drivingly connected to the first screw 3111, and the second gear whose rotation axis is in the y-axis direction is connected to the first end of the first transmission shaft 313, and the first gear is meshed with the second gear, so that the driving cooperation between the first screw 3111 and the first transmission shaft 313 can be achieved.

[0053] like Figure 1As shown, the second screw 3112 and the first transmission shaft 313 are driven and matched through the second commutator 315. The second commutator 315 has three bevel gears inside, namely the first gear, the second gear and the third gear. Among them, the first gear with a rotation axis in the z-axis direction is connected to the second screw 3112, the second gear with a rotation axis in the y-axis direction is connected to the second end of the first transmission shaft 313, and the third gear with a rotation axis in the x-axis direction is connected to the driving unit 32. The first gear is meshed with the second gear and the third gear respectively, so that the third gear can be driven to rotate by the driving unit 32, the third gear drives the first gear to rotate, and the first gear drives the second gear to rotate, so that the driving unit 32 drives the second screw 3112 to rotate, and the second screw 3112 drives the first transmission shaft 313 to rotate.

[0054] like Figure 1 As shown, in this embodiment, the driving unit 32 includes: a second transmission shaft 321 and a first driving device 322. The second transmission shaft 321 is arranged along the first horizontal direction, and the second transmission shaft 321 is drivingly matched with the lifting unit 31; the first driving device 322 is arranged on the bracket 20 and is drivingly connected with the second transmission shaft 321, and the first driving device 322 is used to drive the second transmission shaft 321 to rotate. By setting the second transmission shaft 321 and the first driving device 322, the second transmission shaft 321 can be driven to rotate by the first driving device 322, thereby driving the lifting unit 31 to rise and fall. In this embodiment, the second transmission shaft 321 is drivingly matched with the second screw 3112 in the lifting unit 31.

[0055] Furthermore, there are multiple second transmission shafts 321, and two second transmission shafts 321 that drive and cooperate with each other are arranged between every two adjacent lifting units 31. The first driving device 322 drives the two second transmission shafts 321 to rotate at the same time, so as to drive the two adjacent lifting units 31 to rise and fall synchronously. By using one first driving device 322 to drive the two second transmission shafts 321 to rotate at the same time, synchronous driving can be ensured while improving transmission efficiency.

[0056] like Figure 1 As shown, illustratively, in this embodiment, there are two second transmission shafts 321, and both are arranged along the x-axis direction, the first ends of the two second rotating shafts are arranged opposite to each other and drive and cooperate, the second ends of the two second transmission shafts 321 are separated from each other, and are respectively driven and cooperated with the two lifting units 31, and the second end of each second transmission shaft 321 is driven and cooperated with the second screw rod 3112 in the corresponding lifting unit 31. The first driving device 322 drives and cooperates with the two second transmission shafts 321, thereby driving the four screw rods 311 to rotate synchronously through the two second transmission shafts 321.

[0057] More specifically, the second end of the second transmission shaft 321 is drivingly connected to the third gear of the second commutator 315 , thereby achieving driving cooperation with the first screw rod 3111 .

[0058] like Figure 1 As shown, the two second transmission shafts 321 and the first driving device 322 are driven and matched through the third commutator 323. The third commutator 323 has three bevel gears inside, which are a second gear and two third gears. Among them, the second gear with a rotation axis in the y-axis direction is drive-connected to the first driving device 322, and the two third gears with a rotation axis in the x-axis direction are arranged opposite to each other and are respectively located on both sides of the second gear in the x-axis direction. The two second transmission shafts 321 are drive-connected to the corresponding third gears, and the second gears are respectively meshed with the two third gears.

[0059] In this embodiment, the first driving device 322 is a servo motor, and the output shaft of the servo motor is connected to the second gear. The servo motor drives the second gear to rotate, thereby rotating the two third gears that are simultaneously meshed with the second gear, and then synchronously drives the two second transmission shafts 321 to rotate. The two second transmission shafts 321 respectively drive the corresponding first screw rods 3111 to rotate, and the rotating first screw rod 3111 drives the second screw rod 3112 to rotate through the first transmission shaft 313, thereby realizing the synchronous rotation of the four screw rods 311. By driving the four screw rods 311 to rotate synchronously at the same time by a servo motor, the four connecting members 312 can be synchronously raised or lowered, so that the disassembly and assembly mechanism 10 can be smoothly lifted and lowered, and at the same time, the mechanical transmission efficiency is also improved.

[0060] It should be noted that, in the present embodiment, there are two lifting units 31, which are respectively arranged at positions close to the two ends of the disassembly and assembly mechanism 10 in the x direction, but this is not restrictive. In some other embodiments not shown in the figure, there may be three or four lifting units 31, and a second transmission shaft 321 and a second driving device are arranged between every two adjacent lifting units 31. Correspondingly, the number of second transmission shafts 321 arranged between adjacent lifting units 31 is not restrictive either, that is, one second transmission shaft 321 may be arranged between adjacent lifting units 31, and the two ends of one second transmission shaft 321 are respectively connected to the driving of two adjacent lifting units 31, or three or four second transmission shafts 321 may be arranged. Without violating the principle and inventive concept of the present utility model, the above situations are all within the protection scope of the present utility model.

[0061] like Figure 1 and Figure 2As shown, the bracket 20 includes: a top frame 21, a bottom frame 22 and a support column 23. The support column 23 is connected between the top frame 21 and the bottom frame 22. There are multiple support columns 23, and the multiple support columns 23 are divided into multiple groups in the x-axis direction. The multiple groups of support columns 23 are arranged at intervals in the x-axis direction, and the same group of support columns 23 are arranged at intervals in the y-axis direction, so that a stable support is formed between the top frame 21 and the bottom frame 22.

[0062] like Figure 1 As shown, in this embodiment, the first commutator 314, the second commutator 315 and the third commutator 323 are all fixedly mounted on the top frame 21, the first transmission shaft 313 and the second transmission shaft 321 are rotatably disposed on the top frame 21, and the first driving device 322 is fixedly mounted on the top frame 21.

[0063] The battery pack disassembly and assembly tool also includes a reinforcement device 50. The reinforcement device 50 is arranged on the top of the bracket 20 and is used to be detachably connected to the battery compartment. By setting the reinforcement device 50 to be fixedly connected to the battery compartment, the top frame 21 and the battery compartment are relatively fixed, so that during the process of disassembling and assembling the battery pack 100, the entire bracket 20 is made more stable, and the bracket 20 is effectively prevented from shaking, thereby also improving the accuracy of the control.

[0064] For example, Figure 1 As shown, the reinforcement device 50 includes: an electromagnet 51 and an adjustment frame 52. The electromagnet 51 is used to be fixed to the battery compartment by adsorption; the adjustment frame 52 is connected between the electromagnet 51 and the bracket 20, and is used to adjust the position of the electromagnet 51. When in use, the height of the battery compartment can be adjusted by the adjustment frame 52 according to the height of the battery compartment door, so that the height of the electromagnet 51 is higher than the door of the battery compartment, so that the electromagnet 51 is adsorbed above the door. When the positions of the bracket 20 and the electromagnet 51 are adjusted, the electromagnet 51 is started to adsorb the electromagnet 51 on the battery compartment, thereby fixing the bracket 20 to the battery compartment. After the battery pack 100 is installed or disassembled, the electromagnet 51 is turned off to separate the electromagnet 51 from the battery compartment, so that the bracket 20 can be moved to other positions. By setting the electromagnet 51, the electromagnet 51 can be adsorbed and separated from the battery compartment, which is convenient to operate; and by adopting the adjustment frame 52, the position of the electromagnet 51 can be adjusted according to the height of the battery compartment door, thereby improving the versatility of the reinforcement device 50.

[0065] like Figure 1 and Figure 2As shown, the roller 60 is arranged on the bottom frame 22, and the bottom of the screw rod 311 is rotatably connected to the bottom frame 22. The disassembly and assembly mechanism 10 has a bearing surface 1114 for supporting the battery pack 100; the battery pack disassembly and assembly tool also includes: a leveling mechanism 40. The leveling mechanism 40 is arranged on the bracket 20, and is used to abut against the supporting surface 200 and change the angle between the bracket 20 and the supporting surface 200, so as to adjust the angle between the bearing surface 1114 and the horizontal plane.

[0066] like Figure 4 As shown, the leveling mechanism 40 includes: a support foot 41 and a second driving device 42. The support foot 41 is arranged on the bottom frame 22 of the bracket 20, and the support foot 41 has an extended state and a retracted state. In the extended state of the support foot 41, the support foot 41 abuts against the support surface 200; in the retracted state of the support foot 41, the support foot 41 is separated from the support surface 200; the second driving device 42 is fixedly connected to the bracket 20, and the second driving device 42 is drivingly connected to the support foot 41, and is used to drive the support foot 41 to switch between the extended state and the retracted state; in the extended state of the support foot 41, the second driving device 42 is also used to drive part of the bracket 20 to rise or fall, so as to adjust the angle between the bracket 20 and the support surface 200.

[0067] Specifically, the support leg 41 includes: a mounting seat 411, a connecting column 412, a top plate 413 and a bottom plate 414. The mounting seat 411 is fixedly connected to the bottom frame 22, and a through hole is provided on the mounting seat 411. The connecting column 412 is movably inserted into the through hole. The top of the connecting column 412 is fixedly connected to the top plate 413, and the bottom of the connecting column 412 is fixedly connected to the bottom plate 414. When the support leg 41 is retracted, the bottom plate 414 is separated from the support surface 200 so that the roller 60 contacts the support surface 200. When the support leg 41 is extended, the bottom plate 414 abuts against the support surface 200. The second driving device 42 is an electric cylinder, which is fixedly connected to the reinforcement beam 231 between the support columns 23 of the bracket 20. The telescopic rod 421 of the electric cylinder is fixedly connected to the top plate 413. The electric cylinder controls the telescopic rod 421 to contract and switches the supporting foot 41 to the retracted state. The electric cylinder controls the telescopic rod 421 to extend and switches the supporting foot 41 to the extended state. When the supporting foot 41 is in the extended state, the electric cylinder continues to extend the telescopic rod 421. At this time, since the bottom plate 414 has been against the supporting surface 200, the electric cylinder will reversely drive the reinforcing beam 231 to rise, thereby adjusting the setting angle of the bracket 20.

[0068] For example, there are four supporting legs 41 in groups of two, and the second driving devices 42 are arranged one by one with the supporting legs 41, and the second driving devices 42 are drivingly connected to the corresponding supporting legs 41; the supporting legs 41 in the same group are spaced apart along the second horizontal direction, and the supporting legs 41 in different groups are spaced apart along the first horizontal direction. Figure 5 As shown, the bottom frame 22 has two groups of support feet 41 arranged at intervals in the x-axis direction, one of which is arranged Figure 5 The other set is located at the upper and lower sides of the left end of the middle bottom frame 22. Figure 5 The upper and lower sides of the middle bottom frame 22 near the right end. By adopting this setting mode, in actual use, if the support surface 200 is not a horizontal plane, the four corresponding positions of the bottom frame 22 can be raised to different degrees by adjusting the extension degree of the four supporting feet 41 respectively, so that the setting angle of the overall bracket 20 is changed, and then the angle of the bearing surface 1114 on the disassembly and assembly mechanism 10 connected to the bracket 20 is also changed accordingly, so as to adjust the angle of the bearing surface 1114 so that the bearing surface 1114 can be parallel to the horizontal plane, thereby facilitating the installation and removal of the battery pack 100.

[0069] It should be noted that in another embodiment not shown in the figure, a spring is sleeved on the connecting column 412, and the spring is located between the top plate 413 and the mounting seat 411 to improve the stability between the top plate 413 and the mounting seat 411 to prevent the connecting column 412 from colliding with the inner wall of the through hole.

[0070] like Figure 1 As shown, in this embodiment, the battery pack disassembly and assembly tool further includes: a mobile power supply 70 and an electric box 80. The mobile power supply 70 is arranged on the bottom frame 22 of the bracket 20, and is used to supply power to the disassembly and assembly mechanism 10 and / or the lifting mechanism 30. The electric box 80 is arranged above the mobile power supply 70. The mobile power supply 70 is electrically connected to the disassembly and assembly mechanism 10 and / or the lifting mechanism 30 through the electric box 80, so as to control the power circuit of the disassembly and assembly mechanism 10 and / or the lifting mechanism 30 through the electric box 80. By providing the mobile power supply 70, the disassembly and assembly mechanism 10 and / or the lifting mechanism 30 can be supplied with power without an external power supply, thereby facilitating outdoor work without an external power supply.

[0071] like Figure 2 As shown, the assembly and disassembly mechanism 10 includes: a battery pack moving mechanism 11 and an adjustment mechanism 12. The battery pack moving mechanism 11 is used to drive the battery pack 100 to move in the first horizontal direction, so that the battery pack 100 moves between an assembly position connected to the battery holder 20 and a disassembly position separated from the battery holder 20; the adjustment mechanism 12 is connected to the holder 20 in a liftable manner and is drivingly connected to the lifting mechanism 30. The battery pack moving mechanism 11 is arranged on the adjustment mechanism 12, and the adjustment mechanism 12 is used to adjust the position of the battery pack moving mechanism 11 so that the battery holder 20 is located on the moving path of the battery pack 100.

[0072] For example, Figure 6As shown, the battery pack moving mechanism 11 includes: a bearing seat 111, an actuator 112, a transmission assembly 113 and a third driving device 114. The bearing seat 111 is used to bear the battery pack 100. The bearing seat 111 has a bearing surface 1114. The battery pack 100 is movably disposed on the bearing surface 1114, and the disassembly position is located on the bearing surface 1114 of the bearing seat 111. The actuator 112 is movably disposed on the bearing seat 111 along the x-axis direction, and is used to drive the battery pack 100 to move between the disassembly position and the assembly position. The transmission assembly 113 is movably disposed on the bearing seat 111 along the x-axis direction, and the actuator 112 is drivingly connected to the transmission assembly 113; the third driving device 114 is drivingly connected to the transmission assembly 113, and the third driving device 114 drives the actuator 112 to move along the x-axis direction through the transmission assembly 113.

[0073] If the battery pack 100 needs to be installed in the assembly position on the battery holder 20, after the battery pack 100 is placed in the disassembly position on the support seat 111, the third driving device 114 drives the actuator 112 to move along the x-axis direction through the transmission assembly 113, and the battery pack 100 is moved from the disassembly position to the assembly position on the battery holder 20, thereby completing the pushing of the battery pack 100. If the battery pack 100 needs to be removed from the assembly position on the battery holder 20, the third driving device 114 drives the actuator 112 to move in the x-reverse direction through the transmission assembly 113, and the battery pack 100 is moved from the assembly position on the battery holder 20 to the disassembly position, thereby completing the removal of the battery pack 100. The battery pack moving mechanism 11 of the utility model uses the actuator 112 to complete the installation and disassembly of the battery pack 100, thereby improving the work efficiency of the disassembly of the battery pack 100.

[0074] For example, Figure 6 As shown, the bearing seat 111 has a first slide rail 1115, and the transmission assembly 113 includes: a first slider 1131, a second slider 1132, a pressure sensor 1133 and an elastic member 1134. The first slide rail 1115 is arranged on the bearing seat 111 along the x-axis direction, the first slider 1131 and the second slider 1132 are both movably arranged on the first slide rail 1115 along the x-axis direction, the first slider 1131 is drivingly connected to the driving device, the second slider 1132 is elastically connected to the first slider 1131, and the actuator 112 is drivingly connected to the second slider 1132; the pressure sensor 1133 is arranged between the first slider 1131 and the second slider 1132 to detect the force between the first slider 1131 and the second slider 1132. In this embodiment, the first slider 1131 and the second slider 1132 are elastically connected through the elastic member 1134, and optionally, the elastic member 1134 is a spring.

[0075] When in use, the first slider 1131 reciprocates along the x-axis direction driven by the third driving device 114. During the movement of the first slider 1131, the first slider 1131 transmits the driving force to the second slider 1132 through the elastic member 1134, and the second slider 1132 transmits the driving force to the battery pack 100 through the actuator 112. By setting a pressure sensor 1133 between the first slider 1131 and the second slider 1132, the pressure sensor 1133 can be used to detect the magnitude of the force between the first slider 1131 and the second slider 1132. Due to the principle of action and reaction force, the magnitude of the force detected by the pressure sensor 1133 is the magnitude of the driving force of the actuator 112 acting on the battery pack 100. During use, the pressure sensor 1133 and the third drive device 114 will be respectively connected to the control device for communication. When the battery pack 100 is stuck, the driving force value detected by the pressure sensor 1133 will exceed the preset value. At this time, the control device will control the third drive device to stop working to avoid damage to the battery pack 100 or the battery pack moving mechanism 11.

[0076] like Figure 6 As shown, in this embodiment, the third driving device 114 includes: a first lead screw 1141 and a first driving motor 1142. The first lead screw 1141 is arranged on the bearing seat 111 along the x-axis direction, and the first lead screw 1141 is threadedly matched with the first slider 1131, and the first lead screw 1141 drives the first slider 1131 to move by rotation. When in use, the first drive motor 1142 drives the first lead screw 1141 to rotate, so that the rotating first lead screw 1141 drives the first slider 1131 to move along the x-axis direction, so as to drive the actuator 112 to move, and then drive the battery pack 100 to move along the x-axis direction.

[0077] like Figure 6 As shown, in this embodiment, the execution part 112 includes: a push-pull rod, which is arranged along the x-axis direction. The first end of the push-pull rod is provided with a first fixing groove, which is used to cooperate with the connecting edge on the outer peripheral side of the battery pack 100, and the second end of the push-pull rod is fixedly connected to the second slider 1132. The groove walls on both sides of the first fixing groove are provided with first pin holes, and the first fixing pin is detachably arranged in the first pin hole. When in use, the connecting edge of the battery pack 100 is located in the first fixing groove, and the connecting edge is provided with a second pin hole, which corresponds to the first pin hole. The first fixing pin passes through the two pin holes, so that the push-pull rod and the battery pack 100 are fixedly connected, so that the push-pull rod can push or pull the battery pack 100 to move along the x-axis direction. It can be understood that in this embodiment, there are two push-pull rods, and the two push-pull rods are arranged at intervals along the y-axis direction. The stability of transporting the battery pack 100 can be improved by providing two push-pull rods.

[0078] like Figure 6As shown, the bearing seat 111 includes: a mounting plate 1111, a side plate 1112 and a support bar 1113. The length direction of the mounting plate 1111 is the x-axis direction, and the width direction of the mounting plate 1111 is the y-axis direction. The side plates 1112 are arranged on both sides of the mounting plate 1111 to limit the battery pack 100. At the same time, the side plates 1112 also play a protective role, reducing the movement path of the battery pack 100 during manual operation, thereby reducing safety hazards.

[0079] In the x-axis direction, the mounting plate 1111 has a first end and a second end. The third driving device 114 is mounted on the first end of the mounting plate 1111 . The second end of the mounting plate 1111 is the entry and exit end of the battery pack 100 .

[0080] like Figure 6 As shown, the first slide rail 1115 is arranged on the mounting plate 1111 along the first direction, and the transmission assembly 113 is movably arranged on the mounting plate 1111.

The two support bars 1113 are arranged on the mounting plate 1111 at intervals in the y-axis direction, and the two support bars 1113 are respectively located and attached to the two side plates 1112. The support bar 1113 is provided with a bearing surface 1114 for supporting the battery pack 100, and the bearing surface 1114 is a smooth surface to reduce the friction with the battery pack 100.

[0081] By providing two support bars 1113 , compared with the entire mounting plate 1111 , the contact area between the support seat 111 and the battery pack 100 can be reduced, thereby reducing the friction force with the battery pack 100 .

[0082] The battery pack moving mechanism 11 further includes a positioning device 115. The positioning device 115 is connected to the side plate 1112 and is close to the second end of the mounting plate 1111. The positioning device 115 is used to position the orientation of the bearing seat 111. Figure 6 As shown, in this embodiment, the positioning device 115 is a laser emitter, and the emission direction of the laser emitter is parallel to the moving direction of the battery pack 100, so that the inlet and outlet ends of the battery pack 100 and the battery holder 20 are accurately positioned.

[0083] The adjusting mechanism 12 includes a rotating mechanism 121 and a translating mechanism 122 .

[0085] Exemplarily, the rotating mechanism 121 further includes: a second lead screw 1213, a third slider 1214 and a steel ball roller 1215. The support plate 1211 is arranged parallel to the bearing surface 1114 of the bearing seat 111, and the steel ball roller 1215 is fixedly connected to the support plate 1211. There are multiple steel ball rollers 1215, and multiple steel ball rollers 1215 are evenly arranged on the support plate 1211. There are multiple steel ball rollers 1215, and the mounting plate 1111 of the bearing seat 111 is placed on multiple steel ball rollers 1215, and multiple steel ball rollers 1215 are supported on the mounting plate 1111 at the same time, so that the bearing seat 111 moves relative to the support plate 1211.

[0086] A pivot shaft 1212 is provided on the support plate 1211 along the z-axis direction, and the support plate 1211 is connected to the mounting plate 1111 through the pivot shaft 1212, so that the bearing seat 111 can swing relative to the support plate 1211. The second lead screw 1213 is provided on the support plate 1211 along the y-axis direction, the third slider 1214 is fixedly connected to the mounting plate 1111, and the third slider 1214 is threadedly engaged with the second lead screw 1213, and the second lead screw 1213 drives the third slider 1214 to move along the y-axis direction by rotating, so that the bearing seat 111 swings in the y-axis direction, and the third slider 1214 is driven to move along the y-axis direction by the second lead screw 1213, so that the rotation angle of the bearing seat 111 around the pivot shaft 1212 can be accurately controlled, thereby improving the adjustment accuracy.

[0087] Furthermore, the rotating mechanism 121 further includes: a bearing wheel 1216. The bearing wheel 1216 is disposed on the third slider 1214, and the third slider 1214 is pressed against the support plate 1211 through the bearing wheel 1216. The bearing wheel 1216 is used to provide a supporting force to the third slider 1214 to prevent the third slider 1214 from bending the second lead screw 1213 after being pressed, causing the third slider 1214 and the second lead screw 1213 to be stuck, thereby improving the stability of the rotating mechanism 121.

[0088] The rotating mechanism 121 further includes: a second slide rail 1217 and a limit block 1218, and a guide wheel 1116 is provided at the bottom of the mounting plate 1111.

The limit blocks 1218 are provided at both ends of the second slide rail 1217 to limit the moving range of the guide wheel 1116, thereby limiting the rotation angle of the bearing seat 111 to avoid collision caused by excessive rotation angle.

[0089] The rotating mechanism 121 also includes: a first position sensor 1219. A first baffle 1117 is arranged at the bottom of the mounting plate 1111. By setting the first position sensor 1219, the position of the first baffle 1117 can be detected by the first position sensor 1219 to determine whether the rotation angle of the supporting seat 111 reaches the preset position.

Each fourth slider 1224 is fixedly connected to the support plate 1211 so that the support plate 1211 moves along the y-axis direction on the third slide rail 1222.

[0095] In this embodiment, there are four guide rails, which are spaced in groups of two along the x-axis direction, and the same group of guide rails are spaced in the y-axis direction. By providing four guide rails, it can be ensured that the disassembly and assembly mechanism 10 will not swing left and right or forward and backward during the lifting process, and the screw 311 of the lifting mechanism 30 can be protected during the lifting of the battery pack 100, thereby ensuring the safety and reliability of the tooling.
