Technical Field
[0001] This invention relates to the field of battery manufacturing technology, and in particular to an energy storage module, battery pack and hoisting equipment. Background Technology
[0002] In the current production of battery packs, multiple energy storage modules need to be hoisted one by one into the battery pack housing. Before the battery pack is placed into the housing, the welded energy storage modules need to be transported by hoisting fixtures and undergo ultrasonic cleaning and other processes, which is time-consuming. Currently, the side-clamping hoisting solution is commonly used for energy storage modules. However, due to the complex structure of the modules and the difficulty in precisely controlling the clamping force and movement, it is easy to cause local overvoltage in the modules or cells, which poses a risk of product damage.

A first driving component is disposed on the substrate. The first driving component drives the hanging member to move towards or away from each other along the first direction, so that the second mating part and the first mating part are mated and connected.
[0010] In one embodiment, the hanging component includes: A connecting plate is slidably connected to the substrate and is also drive-connected to the first driving component; A hook is movably connected to the connecting plate, allowing the hook to move relative to the connecting plate in a third direction.

[0023] In existing battery pack production, a battery pack housing contains multiple battery modules. Therefore, the energy storage modules 10 need to be hoisted into the battery pack housing one by one. On the one hand, before the battery pack is placed into the housing, it needs to undergo hoisting, transportation, and ultrasonic cleaning processes, which are time-consuming. The current mainstream side-clamping hoisting solution has problems with precise control of clamping force and movement due to the complex module structure, which can easily lead to local overvoltage damage to the module or cell 11.
[0024] Therefore, this application proposes an energy storage module 10, which includes: a battery cell 11 having a first side and a second side facing each other; a plurality of battery cells 11 are arranged sequentially along a first direction 1 to form a battery pack, wherein the first side of any battery cell 11 is attached to the second side of the adjacent battery cell 11. End plates 12 are located at both ends of the battery pack along the first direction 1, and the two end plates 12 cooperate to clamp the battery cell 11. The first mating part 13 is provided on both opposite sides of the two end plates 12, and the first mating part 13 is used to connect with the hoisting equipment 20.
[0025] like Figure 1 and Figure 3 The energy storage module 10 can be a cuboid structure. The length of the energy storage module 10 is the same as the first direction 1, the width is the same as the third direction 3, and the height is the same as the second direction 2. The center of the energy storage module 10 is a battery pack composed of multiple cells 11. These cells 11 are stacked along the first direction 1, and each cell 11 has a first side and a second side. The first side and the second side can be two sides of the cell 11 along the first direction 1, with the first side of each cell 11 attached to the second side of another adjacent cell 11. Additionally, end plates 12 are provided on both sides of the battery pack along the first direction 1. The two end plates 12 cooperate to clamp the battery pack located between them. Furthermore, steel straps can be used to bind the battery pack and end plates 12 and other components of the energy storage module 10 into a single unit.
[0026] In addition, each end plate 12 is provided with a first mating part 13. The first mating part 13 can be provided on the upper part of the end plate 12 along the second direction 2 and located on opposite sides of the two end plates 12. The first mating part 13 can be a protrusion bent on the end plate 12, and the protrusions on the two end plates 12 extend relative to each other. During hoisting, the structure on the hoisting equipment 20 for connecting with the first mating part 13 can be provided on the side of the first mating part 13 facing the battery pack. During connection, the hoisting equipment 20 moves along the first direction 1 toward the outside of the energy storage module 10 and inserts or snaps into the first mating part 13. Then the hoisting equipment 20 can lift the energy storage module 10. During this process, the hoisting equipment 20 applies a force away from the battery pack to the first mating part 13, so the cell 11 will not be clamped by the hoisting equipment 20, eliminating the risk of pinching injury.
[0027] Figure 3 As shown, in another embodiment of this application, the bundling method of the energy storage module 10 can be flexibly designed according to requirements. For example, the bundling method of the energy storage module 10 can be that multiple battery cells 11 are sandwiched between two end plates 12: end plate 12, battery cell 11, battery cell 11, ..., battery cell 11, end plate 12; in practical applications, more than two end plates 12 can also be used in one energy storage module 10. Specifically, for example, it can be end plate 12a, battery cell 11, battery cell 11, ..., end plate 12b, battery cell 11, battery cell 11, ... The components are: core 11, ..., battery cell 11, end plate 12c; end plates 12a and 12b are bound together with steel straps; end plates 12b and 12c are bound together with steel straps; alternatively, end plates 12a, 11, ..., 12b, 11, 11, 11, ..., 12c, 11, ..., end plate 12d, with end plates 12a and 12b bound together with steel straps, end plates 12b and 12c bound together with steel straps, and end plates 12c and 12d bound together with steel straps. During hoisting, the hoisting equipment 20 can cooperate with the first mating part 13 on end plates 12b and 12c for hoisting. When the number of battery cells 11 between two adjacent end plates 12 is the same, by using a multi-layer end plate configuration, the length of the energy storage module 10 hoisted in a single operation can be increased, thereby improving production efficiency.
[0028] like Figure 4 and Figure 5 In another embodiment of this application, the end plate 12 is provided with a connecting hole 14 extending along the second direction 2, and the first mating part 13 is configured as a hole or protrusion on the inner wall of the connecting hole 14.
[0029] The end plate 12 is provided with a connecting hole 14 extending along the height direction (i.e., the second direction 2) of the energy storage module 10. The connecting hole 14 penetrates the end plate 12 along the second direction 2. In addition, the first mating part 13 is provided at one end of the connecting hole 14. Specifically, the first mating part 13 can be provided at the top of the connecting hole 14 along the second direction 2. This can prevent other parts of the energy storage module 10 from interfering with the hoisting equipment 20 during hoisting and facilitate the connection between the hoisting equipment 20 and the first mating part 13. In addition, the other end of the connecting hole 14 opposite to the first mating part 13 is provided as a mounting hole. This mounting hole can extend along the second direction 2. During battery pack assembly, the mounting hole allows bolts to pass through. Assembly tools such as screwdrivers can pass through the connecting hole 14 and engage with the bolts in the mounting hole to screw the bolts to the battery pack housing, thereby locking the energy storage module 10 onto the housing.
[0030] In another embodiment, the first mating part 13 may be configured as a protrusion or hole on the inner wall of the connecting hole 14. The protrusion and hole are located on the side of the battery pack of the energy storage module 10 away from the connecting hole 14. Correspondingly, the hoisting device 20 is provided with a hole or protrusion adapted to the first mating part 13. When the hoisting device 20 is engaged with the energy storage module 10, the hole or protrusion on the hoisting device 20 will move away from the battery cell 11 along the first direction 1 and engage with the first mating part 13. This causes the end plate 12 to be subjected to a force away from the battery cell 11 along the first direction 1, thereby achieving the effect of the battery cell 11 not being clamped. In this solution, the first mating part 13 is directly machined on the inherent structure of the connecting hole 14, which simplifies the structure of the end plate 12 and facilitates the machining of the end plate 12 while satisfying the hoisting function.
[0031] like Figure 5In another embodiment of this application, in the second direction 2, the connecting hole 14 has a first hole segment 141 located at the upper part, and a first mating part 13 is provided in the first hole segment 141. The first hole segment 141 is located at the upper part of the connecting hole 14 along the second direction 2, and the second hole segment is located at the bottom of the connecting hole 14 along the second direction 2. The shape of the cross section of the first hole segment 141 perpendicular to the second direction 2 is square, so that the hoisting equipment 20 can only move along the first direction 1 when it mates with the first mating part 13. Correspondingly, the shape of the part of the hoisting equipment 20 that connects to the first mating part 13 can also be designed as square. During the engagement of the second mating part 101 and the first mating part 13, the hanging body 1222 can slide and engage with the first hole section 141, limiting the second mating part 101 to engage with the first mating part 13 along a preset trajectory. This improves the accuracy and stability of the engagement between the hoisting equipment 20 and the energy storage module 10. In addition, due to processing or assembly tolerances, the two end plates 12 may have a misalignment after assembly, that is, the center point of the first mating part 13 on the two end plates 12 may not be on the same straight line in the first direction 1. During hoisting, the energy storage module 10 may be subjected to torsional force, which may cause the energy storage module 10 to deform, and the blue film at the bottom of the energy storage module 10 along the second direction 2 may be worn, affecting the insulation performance. In this scheme, since the force is applied directly along the first direction 1, even if there is a misalignment, the energy storage module 10 will not be twisted due to the limitation of the square design, thus eliminating the hidden dangers of torsional deformation and damage to the blue membrane caused by hoisting.
[0032] The present invention also proposes a battery pack having a housing containing a plurality of energy storage modules arranged in a matrix. The specific structure of the energy storage modules is as described in the above embodiments. Since the battery pack adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0033] This application also proposes a hoisting device 20 for hoisting the aforementioned energy storage module 10. The hoisting device 20 includes: The lifting device body 100 includes a base plate 110. The base plate 110 is provided with two hanging members 120 on both sides along the first direction 1, and the two hanging members 120 are arranged on the same side of the base plate 110 along the second direction 2. One end of the hanging member 120 is slidably connected to the substrate 110, and the other end extends along the second direction 2 toward a direction away from the substrate 110; the other end of the hanging member 120 is provided with a second mating part 101, which is used to engage with the first mating part 13. The first driving component 200 is disposed on the substrate 110. The first driving component 200 drives the hanging component 120 to move towards or away from each other along the first direction 1, so that the second mating part 101 and the first mating part 13 are mated and connected.
[0034] like Figure 3 As shown, the lifting equipment 20 in this embodiment can be used to lift the energy storage module 10 in the above embodiment. The energy storage module 10 can be a cuboid structure. The middle part of the energy storage module 10 is a battery pack composed of multiple cells 11. The multiple cells 11 are stacked along the first direction 1. Each cell 11 has a first side and a second side. The first side and the second side can be two sides of the cell 11 along the first direction 1. The first side of each cell 11 is attached to the second side of another cell 11 adjacent to it. In addition, end plates 12 are provided on both sides of the battery pack along the first direction 1. The two end plates 12 cooperate to clamp the battery pack located between them. In addition, steel straps can be used to bind the battery pack of the energy storage module 10 to the end plates 12 and other components into a whole. In addition, each end plate 12 is provided with a first mating part 13. The first mating part 13 can be provided on the upper part of the end plate 12 along the second direction 2 and located on the opposite sides of the two end plates 12. The first mating part 13 can be a protrusion bent on the end plate 12, and the protrusions on the two end plates 12 extend relative to each other.
[0035] Figure 3 As shown, the energy storage module 10 is bundled by sandwiching multiple battery cells 11 between two end plates 12: end plate 12, battery cell 11, battery cell 11, ..., battery cell 11, end plate 12; in practical applications, more than two end plates 12 can also be used in one energy storage module 10. Specifically, for example, it can be end plate 12a, battery cell 11, battery cell 11, ..., end plate 12b, battery cell 11, battery cell 11, ..., battery cell 11, end plate 12c; end plates 12a and 12b are bundled with steel straps; end plates 12b and 12c are bundled with steel straps.
[0036] Alternatively, it can consist of end plate 12a, battery cell 11, battery cell 11, ..., end plate 12b, battery cell 11, battery cell 11, battery cell 11, ..., end plate 12c, battery cell 11, ..., end plate 12d. End plates 12a and 12b are bound together with steel straps, end plates 12b and 12c are bound together with steel straps, and end plates 12c and 12d are bound together with steel straps. During hoisting, they can be used in conjunction with the first mating part 13 on end plates 12b and 12c. When the number of battery cells 11 between two adjacent end plates 12 is the same, by using a multi-layer end plate configuration, the length of the energy storage module 10 that can be hoisted in a single operation can be increased, thereby improving production efficiency.
[0037] like Figure 1 and Figure 2The hoisting equipment 20 includes a hoisting body 100, which can be a rigid frame structure made of high-strength materials such as aluminum or steel. The hoisting body 100 includes a base plate 110, which is the basic structural component of the hoisting body 100 and serves as a support platform for various components on the hoisting equipment 20. Hanging members 120 are respectively provided on both sides of the base plate 110 along the first direction 1. The base plate 110 supports and fixes the hanging members 120 and other components such as the first drive assembly 200. The base plate 110 can be a flat plate structure or a frame structure formed by assembling multiple plates. Linear guide rails are installed on both sides of the base plate 110 along its length direction, extending along the first direction 1.
[0038] like Figure 6 , Figure 7 and Figure 9 The hanging component 120 is a component that directly connects to the energy storage module 10. The hanging component 120 can be a hook structure extending along the second direction 2. One end of the hanging component 120 is slidably connected to the substrate 110 via a linear guide rail, and the other end extends away from the substrate 110 along the second direction 2. In some embodiments, each hanging component 120 can be composed of a slider and a connecting plate 121. The slider is slidably connected to the linear guide rail, and the connecting plate 121 is fixed on the slider. The linear guide rail limits the hanging component 120 to slide only along the extension direction of the linear guide rail. In order to ensure the stability of the sliding of the hanging component 120, multiple linear guide rails can be provided.
[0039] like Figure 8 and Figure 9 A second mating portion 101 is provided at one end of the hanging member 120 away from the base plate 110. In one embodiment, the second mating portion 101 is provided at the bottom of the hanging member 120 along the second direction 2. The second mating portion 101 is a structure for connecting with the first mating portion 13. For example, when the first mating portion 13 is a protrusion or hole in the above embodiment, the second mating portion 101 can be a hole or protrusion that is inserted and mated with the first mating portion 13.
[0040] like Figure 6 and Figure 7The hoisting equipment 20 also includes a first drive assembly 200, which is mounted on the base plate 110 and connected to the hanging member 120 for transmission. The first drive assembly 200 can drive the two hanging members 120 to move towards or away from each other along a first direction 1. To achieve the above function, the first drive assembly 200 can be a two-way cylinder structure. The two hanging members 120 are connected to the first drive assembly 200 and move towards or away from each other under the drive of the first drive assembly 200. The first drive assembly 200 can also be a motor-driven screw mechanism. For example, a screw extending from the first side to the second side is driven by a stepper motor or a servo motor. The two ends of the screw are provided with reverse threads, and each end is threaded to one of the hanging members 120. The rotation of the screw can also drive the two hanging members 120 to move closer to or further away from each other. Of course, the above structure is only an example, and the specific structure of the first drive assembly 200 is not limited in this embodiment.
[0041] During the battery pack production process, when hoisting the energy storage module 10, if... Figure 1 The hoisting equipment 20 is first moved above the energy storage module 10 by manual labor or a robotic arm. Then, the hoisting equipment 20 is lowered so that the first mating part 13 and the second mating part 101 are on the same horizontal plane. At this time, the two second mating parts 101 are located in the area between the two end plates 12. Furthermore, the hoisting equipment 20 and the energy storage module 10 are spaced apart along the top of the second direction 2 to prevent contact with the electrodes on the top of the energy storage module 10, eliminating the risk of short circuits. Figure 2 and Figure 9 After the hoisting equipment 20 is in place, the first drive assembly 200 drives the two second mating parts 101 to move in opposite directions until the second mating parts 101 are engaged and fixed with the first mating parts 13. At this time, the two second mating parts 101 apply opposing forces along the first direction 1 to the two first mating parts 13. After the connection is completed, the hoisting body 100 is lifted, lifting the energy storage module 10 and transferring it to the next work station. During this process, the energy storage module 10 is subjected to an opening force along the first direction 1, and the energy storage module 10 will not be clamped, thus ensuring that the battery cells 11 of the energy storage module 10 are not clamped and damaged. When the hoisting is in place, the two second mating parts 101 move towards each other along the length direction and then separate from the first mating parts 13. In the above scheme, since the length of the energy storage module 10 is usually relatively long, engaging and tensioning along the length direction can reduce the possibility of swaying after the energy storage module 10 is lifted, and better ensure the stability of the lifting.
[0042] like Figure 8 A specific structure of the hanging member 120 is shown. In this embodiment, the hanging member 120 includes: The connecting plate 121 is slidably connected to the base plate 110 and is also connected to the first driving component 200 in a transmission manner. The hook 122 is movably connected to the connecting plate 121, so that the hook 122 moves relative to the connecting plate 121 along the third direction 3. A second mating part 101 is provided at the end of the hook 122 away from the base plate 110.
[0043] The connecting plate 121 is the part of the hanging member 120 used to connect with the base plate 110. The connecting plate 121 can be a flat plate structure, and a slider that slides and engages with the linear guide rail can be provided on the connecting plate 121. In addition, the first driving component 200 is connected to the connecting plate 121 in a driving connection, and the first driving component 200 drives the connecting plate 121 to slide along the linear guide rail. Furthermore, a hook 122 is provided at the bottom of the connecting plate 121 along the second direction 2. The hook 122 is a component that engages with the first mating part 13 on the energy storage module 10. The hook 122 extends along the second direction 2, and a second mating part 101 is provided at the bottom of the hook 122 along the second direction 2. The second mating part 101 can be a hook-shaped structure with a specific shape for hooking the first mating part 13. The first mating part 13 can be a matching hole or groove. Furthermore, the hook 122 is movably connected to the connecting plate 121. This movable connection allows the hook 122 to move relative to the connecting plate 121 along a third direction 3. The movable connection can be implemented in various ways. For example, a groove can be provided on the connecting plate 121, and the hook 122 can move within the groove via a slider; or the hook 122 can be connected to the connecting plate 121 via a hinge structure to achieve a limited angle of swing. With this design, when the second mating part 101 mates with the first mating part 13, the hook 122 can compensate for the misalignment when the first mating part 13 and the second mating part 101 are aligned, ensuring that the second mating part 101 can smoothly mate and connect with the first mating part 13, thus improving lifting efficiency.
[0044] like Figure 8 One method for achieving floating of the hook 122 is shown. In this embodiment, the hook 122 includes: The connector 1221 is fixedly connected to the connector plate 121. The connector 1221 is provided with a slide groove extending along the third direction 3, and the slide groove has an opening at the bottom along the second direction 2. The hanging body 1222 extends along the second direction 2. The top of the hanging body 1222 along the second direction 2 is slidably connected to the slide groove. The bottom of the hanging body 1222 along the second direction 2 is provided with a second mating part 101. An elastomer 1223 elastically connects the hanger 1222 and the connector 1221 so that the hanger 1222 is held in the middle of the chute when it is not subjected to external force.
[0045] The connector 1221 is the part of the hook 122 that is fixed to the connecting plate 121. The connector 1221 can take various structural forms, such as a metal block or frame with a specific shape. To facilitate installation and ensure connection strength, the connector 1221 can be fastened to the connecting plate 121 with screws. In addition, a sliding groove is provided on the connector 1221. The sliding groove extends along the third direction 3 and is rectangular in shape. An opening is provided at the top of the sliding groove along the second direction 2. The shape and size of the opening are equivalent to the shape and size of the sliding groove in the cross section perpendicular to the second direction 2. The sliding groove has a bottom along the second direction 2, and an opening is also provided at the bottom of the sliding groove. The opening is smaller than the size of the bottom of the sliding groove. The hanging body 1222 is a long, rod-shaped structure. The hanging body 1222 protrudes outward from the outer periphery of the top along the second direction 2. The size of the protrusion is larger than the size of the opening at the bottom of the slide groove. The hanging body 1222 can pass through the opening at the top of the slide groove along the second direction 2 and exit through the opening at the bottom of the slide groove. The protruding part of the hanging body 1222 along the top of the second direction 2 can form a limit with the periphery of the opening at the bottom of the slide groove to prevent the hanging body 1222 from coming out of the opening at the bottom of the slide groove. In addition, in the third direction 3, the size of the opening at the bottom of the slide groove on the hanging body 1222 is smaller than the size of the opening at the bottom of the slide groove, so that the hanging body 1222 can slide in the slide groove along the third direction 3, and the sliding stroke is limited by the size of the opening at the bottom of the slide groove. In addition, the second mating part 101 mentioned above is provided at the bottom of the hanging body 1222 along the second direction 2. Furthermore, an elastic body 1223 can be embedded within the chute. The elastic body 1223 can be a common helical spring. Along the width direction of the energy storage module 10, one elastic body 1223 can be respectively provided on both sides of the hanging body 1222. One end of the elastic body 1223 is connected to the inner wall of the chute, and the other end is connected to the hanging body 1222. The two elastic bodies 1223 cooperate to clamp the hanging body 1222, so that the hanging body 1222 remains in the middle position of the chute when no external force is applied. For example, in order to force the hanging body 1222 to remain in the middle position of the chute when no external force is applied, two elastic bodies 1223 of equal length can be used to clamp the hanging body 1222. When the hook 122 is connected to the energy storage module 10, the hanging body 1222 can slide along the slide groove to compensate for the positional deviation between the second mating part 101 and the first mating part 13, ensuring that the first mating part 13 and the second mating part 101 are accurately connected. When the hanging body 1222 slides, the elastic body 1223 will deform to store energy. After the hoisting is completed, when the second mating part 101 is disengaged from the first mating part 13, the hanging body 1222 will return to the initial position under the drive of the elastic body 1223. This ensures that the hanging body 1222 remains in a fixed position during each hoisting, ensuring that the second mating part 101 can accurately connect with the first mating part 13 each time, thus ensuring the smoothness and reliability of the hoisting process.
[0046] like Figure 7 and Figure 9 In another embodiment of this application, the hanging component 120 further includes an insulating component 123; wherein the insulating component 123 is disposed between the hook 122 and the connecting plate 121, or between the connecting plate 121 and the base plate 110; wherein the insulating component 123 can be in the form of an insulating gasket, an insulating sleeve, etc., and its material can be rubber, plastic, or composite material, etc. The insulating component 123 can be disposed between the hook 122 and the connecting plate 121, or between the connecting plate 121 and the base plate 110. When disposed between the hook 122 and the connecting plate 121, the connecting body 1221 of the hook 122 can cooperate with the connecting plate 121 to clamp the insulating gasket. In addition, the position on the connecting body 1221 that is connected to the connecting plate 121 by screws can be provided with an insulating gasket. The insulating sleeve isolates the screw from the connector 1221, thus isolating the hook 122 from the connecting plate 121. Even if the hook 122 accidentally touches the contacts on the energy storage module 10 during hoisting, the presence of the insulating element 123 will not cause the energy storage module 10 to short-circuit through the hook 122, avoiding electrical short-circuit accidents that may occur during hoisting operations and ensuring the safety of operators and equipment. Similarly, when the insulating element 123 is located between the connecting plate 121 and the base plate 110, the insulating element 123 can be clamped between the slider of the linear guide rail on the base plate 110 and the connecting plate 121. The screw between the slider and the connecting plate 121 can also be fitted with an insulating sleeve, which can achieve the same electrical isolation effect as described above, and will not be elaborated here.
[0047] In addition, such as Figure 7 In order to improve the stability of hoisting, in another embodiment of this application, multiple hooks 122 can be provided, and multiple hooks 122 can be fixed on the same connecting plate 121. Specifically, on each hanging component 120, multiple hooks 122 can be set along the third direction 3. Multiple hooks 122 are fixed together on the same connecting plate 121 to ensure the accuracy of the relative position of the hooks 122, thereby ensuring the accuracy of the fit with the end plate 12. The first drive component 200 can drive the multiple hooks 122 on each hanging component 120 to move synchronously. When the first drive component 200 drives these hooks 122 to connect with the first mating part 13 of the energy storage module 10, multiple hooks 122 can be connected to the energy storage module 10 at the same time, so as to evenly distribute the weight of the energy storage module 10 to multiple hooks 122. This can enhance the balance and anti-sway ability of the energy storage module 10 during the hoisting process and reduce the risk of structural deformation or damage to the internal cells 11 of the energy storage module 10 due to unstable hoisting or local stress concentration.
[0048] like Figure 7 and Figure 9In another embodiment of this application, the lifting device body 100 further includes a limiting member 130. The limiting member 130 is disposed on the side of each hanging member 120 opposite to the other hanging member 120 and connected to the base plate 110. In the second direction 2, the projection of the limiting member 130 at least partially overlaps with the sliding trajectory of the hanging member 120. Specifically, plates extending in the second direction 2 can be provided at both ends of the base plate 110 along the first direction 1. The aforementioned limiting member 130 is provided on each plate. The limiting member 130 can be a bolt screwed onto the plate, extending in the first direction 1. By screwing the limiting member 130, the limiting member 130 can be moved along the first direction 1. Furthermore, the limiting member 130 is also located on the sliding path of the hanging member 120. Specifically, in the first direction 1, the projection of the limiting member 130 overlaps with the projection of the hanging member 120, and the limiting member 130 also at least partially overlaps with the linear guide rail on the base plate 110. When the first drive assembly 200 drives the hanging component 120 to move, the hanging component 120 can abut against the limiting component 130. By adjusting the position of the limiting component 130, the position of the hanging component 120 when it abuts against the limiting component 130 can be adjusted, thereby adjusting the stroke of the hanging component 120. This ensures that the hanging component 120 and the first mating part 13 on the end plate 12 are properly mated, which can prevent the energy storage module 10 from bearing excessive tension and prevent damage to the energy storage module 10. It also ensures that the first mating part 13 and the second mating part 101 can be reliably mated, thus ensuring the reliability of the hoisting process.
[0049] In addition, such as Figure 9 In another embodiment of this application, the first drive assembly 200 includes two first drive members 210, both of which are disposed on the lifting body 100. Each first drive member 210 is connected to one of the second mating parts 101. The first drive members 210 can be two independent cylinders with piston rods arranged opposite to each other and capable of extending and retracting in opposite directions. Through the cooperation of the two first drive members 210, each second mating part 101 can be driven independently. Combined with the aforementioned limiting member 130, more precise and free movement control of the two hanging members 120 can be achieved.
[0050] like Figure 2 In another embodiment of this application, the hoisting equipment 20 further includes a support mechanism 300, which is movably mounted on the hoisting body 100; The 300 supporting institutions include: The pallet 310 is movably mounted on the lifting body 100 to have a first position and a second position. In the first position, the pallet 310 and the energy storage module 10 overlap at least partially in the third direction 3, and the pallet 310 is used to support the bottom of the energy storage module 10 along the second direction 2. In the second position, the pallet 310 and the energy storage module 10 are offset in the third direction 3, and the pallet 310 moves to above the energy storage module 10 along the second direction 2. The second drive assembly 320 is mounted on the lifting device body 100 and is connected to the pallet 310 for transmission.
[0051] The support mechanism 300 is used to provide support for the energy storage module 10 during hoisting, preventing the bottom of the energy storage module 10 from sagging and deforming during long-term hoisting. The support mechanism 300 may include a support plate movably connected to the lifting body 100. The support plate is driven by a robotic arm, a cylinder, or a hydraulic cylinder. The support mechanism 300 can move above the energy storage module 10 along the second direction 2, or move below the energy storage module 10 along the second direction 2 and support the energy storage module 10. During hoisting, the support mechanism 300 is initially in the second position. After the lifting body 100 descends and connects with the energy storage module 10, it lifts the energy storage module 10. Then, the support mechanism 300 moves to the first position and supports the bottom of the energy storage module 10 along the second direction 2. Afterward, the hoisting equipment 20 transfers the energy storage module 10 to other positions such as the ultrasonic cleaning station. During this process, the support mechanism 300 always supports the bottom of the energy storage module 10 along the second direction 2 to prevent the cells 11 on the energy storage module 10 from sagging. When the energy storage module 10 is finally placed into the box, the support mechanism 300 can switch to the second position to avoid interference with other components. Through the above technical solution, when the hoisting equipment 20 hoists the energy storage module 10, the supporting mechanism 300 can flexibly switch between the first position and the second position as needed. In the first position, the supporting mechanism 300 provides stable support for the energy storage module 10, preventing the module from sagging in the middle or other positions due to lack of support during hoisting, thus reducing the risk of product damage. In the second position, the supporting mechanism 300 moves above the energy storage module 10, preventing its shape from exceeding the module boundary, thereby solving the problem of interference with other energy storage modules 10 when operating in narrow spaces such as when the energy storage module 10 is placed in the container, and improving the stability and safety of the hoisting process.
[0052] like Figure 10In another embodiment of this application, the support mechanism 300 includes a support plate 310, which can be a flat plate structure and made of high-strength material. The support plate 310 is movably mounted on the lifting body 100. For example, the support plate 310 can be connected to the base plate 110 of the lifting body 100 by means of hinge rotation connection or guide rail sliding connection. Through movement, the support plate 310 has different first and second positions on the base plate 110. In the first position, part of the structure of the support plate 310 can be moved to the lower part of the energy storage module 10 along the second direction 2. At this time, the part of the support plate 310 located below the energy storage module 10 can overlap with the energy storage module 10 in the third direction 3 and contact the bottom of the energy storage module 10 along the second direction 2. In the second position, the support plate 310 is offset from the energy storage module 10 in the third direction 3, and the support plate 310 moves upward and disengages from the bottom of the energy storage module 10 along the second direction 2, and finally moves above the energy storage module 10. The second drive assembly 320 is used to drive the pallet 310 to move between the first position and the second position. This second drive assembly 320 can take various forms; for example, when the pallet 310 is rotatably connected to the lifting device body 100, the second drive assembly 320 can be a motor structure that drives the pallet 310 to rotate. Through the above technical solution, the pallet 310 of the supporting mechanism 300 can achieve automatic position adjustment, which not only ensures the stability of the support for the energy storage module 10 but also improves operational efficiency and automation level, thereby enhancing the reliability of the energy storage module 10 transfer process.
[0053] like Figure 10 As shown, in one embodiment, the second drive component 320 includes: The second driving member 321 is disposed on the substrate 110, and the second driving member 321 has a second driving end that moves along the second direction 2. The third driving member 322 is disposed at the second driving end and moves along the second direction 2 under the drive of the second driving member 321. The third driving member 322 has a third driving end that moves along the third direction 3. The fourth driving member 323 is disposed at the third driving end and moves along the third direction 3 under the drive of the third driving member 322. The fourth driving member 323 has a fourth driving end that moves along the second direction 2. The fourth driving end is connected to the tray 310 and drives the tray 310 to move along the second direction 2.
[0054] The second driving component 321 can be an electric actuator or a cylinder, etc. The second driving component 321 is fixed to the base plate 110. The second driving end can be provided with a mounting base or other connecting structure to connect with the third driving component 322. The second driving end moves up and down along the second direction 2 to drive the pallet 310 to move along the second direction 2. The third driving component 322 is located on the second driving end. The third driving component 322 can move along the second direction 2 under the drive of the second driving component 321. The main function of the third driving component 322 is to drive the pallet 310 to move along the third direction 3. The third driving component 322 can be a cylinder or other structure that extends and retracts along the third direction 3. The third driving end is the part of the third driving component 322 that moves along the third direction 3. The third driving end can also be provided with a mounting base or other connecting structure to connect with the fourth driving component 323 to drive the fourth driving component 323 to move along the third direction 3. The fourth drive member 323 also provides driving force along the second direction 2, driving the pallet 310 to move along the second direction 2. The fourth drive member 323 can adopt the same structural form as the second drive member 321, such as a cylinder or electric push rod. The fourth drive end is the part of the fourth drive member 323 that moves along the second direction 2, and the pallet 310 can be fixedly installed on the fourth drive end.
[0055] With the above-described multi-stage drive structure, the pallet 310 can perform two-stage movement in the second direction 2 and one-stage movement in the third direction 3. The movement of the second drive assembly 320 in the above structure will be described below: Before the hoisting equipment 20 hoists the energy storage module 10, the second and fourth drive ends first retract upwards, causing the pallet 310 to move to a position above the energy storage module 10 that it cannot touch. Then, the hoisting equipment 20 descends and connects with the energy storage module 10. At this time, the pallet 310 does not yet support the energy storage module 10. After the hoisting equipment 20 lifts the energy storage module 10, the third drive end first drives the pallet 310 away from the energy storage module 10 along the third direction 3, causing the pallet 310 to move away from the energy storage module 10 in the third direction 3. The second drive assembly 320 is positioned offset from the energy storage module 10 to ensure that it does not collide or interfere with the energy storage module 10 during its subsequent descent. Then, both the second and fourth drive ends descend, causing the portion of the support plate 310 for the energy storage module 10 to move below it along the second direction 2. Next, the third drive end moves in the opposite direction, causing the portion of the support plate 310 for the energy storage module 10 to overlap with it in the second direction 2. Then, either the second or fourth drive end rises, bringing the support plate 310 into contact with the energy storage module 10, thus providing support. When it is necessary to release the support, the second drive assembly 320 simply operates in the reverse order of the above actions, which will not be elaborated further here.
[0056] As can be seen from the above-described operation process, by using the second drive component 320, while ensuring the support function for the energy storage module 10 is achieved, the support plate 310 will not interfere with the sides and bottom of the energy storage module 10 during the support process, eliminating the risk of damage to the energy storage module 10. Furthermore, as... Figure 6 and Figure 10 The pallet 310 can be a flat plate structure parallel to the side of the energy storage module 10, and the bottom of the pallet 310 along the second direction 2 can be bent to form a structure supporting the bottom of the energy storage module 10. In this way, when the third drive end moves in the opposite direction, the pallet 310 can fit against the side of the energy storage module 10 or abut against the bottom of the energy storage module 10, which can improve the support effect of the energy storage module 10 and ensure the stability of the state and the accuracy of the position of the energy storage module 10 during the transfer process.
[0057] like Figure 10 In another embodiment of this application, the second driving component 320 further includes: The first mounting plate 324 is slidably connected to the base plate 110 to move along the second direction 2, the second driving end is fixedly connected to the first mounting plate 324, and the third driving member 322 is fixedly mounted on the first mounting plate 324. The second mounting plate 325 is slidably connected to the first mounting plate 324 to move along the third direction 3. The third drive end is fixedly connected to the second mounting plate 325. The fourth drive member 323 is fixedly installed on the second mounting plate 325. The support plate 310 is slidably connected to the second mounting plate 325 and fixedly connected to the fourth drive end.
[0058] The first mounting plate 324 is the main load-bearing component in the support mechanism 300. The first mounting plate 324 is a flat plate structure and can be slidably connected to the bottom of the lifting body 100 along the second direction 2. For example, multiple guide rods can be evenly spaced along the edge of the first mounting plate 324, and guide sleeves are set at corresponding positions on the base plate 110. The guide rods and guide sleeves slide together, so that the first mounting plate 324 can move along the height direction of the energy storage module 10. The second drive end is fixedly connected to the middle of the first mounting plate 324 to drive the first mounting plate 324 to rise and fall. In addition, the third drive member 322 is fixed on the first mounting plate 324. The second mounting plate 325 is slidably connected to the first mounting plate 324. The second mounting plate 325 is disposed on one end of the first mounting plate 324 along the third direction 3. The second mounting plate 325 and the first mounting plate 324 are slidably connected through a guide rail and slider structure. The second mounting plate 325 can slide relative to the first mounting plate in the third direction 3. In addition, the third connecting end 311 is fixedly connected to the second mounting plate 325, driving the second mounting plate 325 to move. Furthermore, a guide rail extending along the second direction 2 is disposed on the side of the second mounting plate 325 opposite to the first mounting plate 324. A slider that cooperates with the guide rail is disposed on the support plate 310. The slider is slidably connected to the guide rail, so that the support plate 310 and the second mounting plate 325 are slidably engaged. The fourth driving member 323 can be disposed on the second mounting plate 325, and the fourth driving end is connected to the support plate 310.
[0059] The specific movement process of the above structure will be described below: Before the hoisting equipment 20 hoists the energy storage module 10, the pallet 310 moves to a position above the hanging component 120 along the second direction 2; then the hoisting equipment 20 descends and connects with the energy storage module 10. At this time, the pallet 310 is above the energy storage module 10 along the second direction 2. After the hoisting equipment 20 lifts the energy storage module 10, the third drive component 322 first drives the second mounting plate 325 to move along the first direction 1 along the third direction 3, causing the pallet 310 and the fourth drive component 323 to move synchronously away from the first mounting plate 324, so that the position of the pallet 310 and the energy storage module 10 is staggered, ensuring that the pallet 310 will not collide or interfere with the energy storage module 10 during the subsequent descent of the pallet 310; then the first mounting plate 324 moves away from the first drive component 324 along the third direction 325. Driven by the actuator 210, the lower component moves downward along the second direction 2. Driven by the fourth actuator 323, the support plate 310 moves downward along the second direction 2, causing the portion of the support plate 310 supporting the energy storage module 10 to move below the energy storage module 10 along the second direction 2. Then, the third actuator 322 drives the second mounting plate 325 to move in the opposite direction, allowing the support plate 310 to clamp onto the side wall of the energy storage module 10 along the third direction 3. Simultaneously, the portion supporting the energy storage module 10 overlaps with the energy storage module 10 in the second direction 2. Then, the second actuator 321 drives the first mounting plate 324 to move upward along the second direction 2, causing the support plate 310 to move upward along the second direction 2, bringing it into contact with the bottom of the energy storage module 10 along the second direction 2, thus supporting the energy storage module 10. When it is necessary to release the support, the hoisting equipment 20 simply operates in the reverse order of the above actions, which will not be elaborated further here. In the above scheme, by setting the first mounting plate 324 and the second mounting plate 325, the movement of the support plate 310 in the height and width directions can be more stable and the positional accuracy is higher. Moreover, the structural strength between the support plate 310 and the first connecting end 311 is also higher, which can ensure the stability and reliability of supporting the energy storage module 10.
[0060] In another embodiment of this application, the second drive component 321 can be configured as a thin cylinder, and the fourth drive component 323 can be configured as a rodless cylinder. Since the thin cylinder has a small thickness and the rodless cylinder has no extended piston rod, the size of the second drive component 320 in the second direction 2 can be reduced, so that the hoisting equipment 20 can be adapted to the hoisting and transportation of the energy storage module 10 in a small space.
[0061] like Figure 6In another embodiment of this application, the energy storage module 10 is provided with support plates 310 on both sides along the third direction 3, and two second drive components 320 are provided, each second drive component 320 being connected to one of the support plates 310; the two support plates 310 can be raised and lowered synchronously, so that the hoisting equipment 20 can simultaneously support two opposite areas at the bottom of the energy storage module 10 along the second direction 2, further improving the hoisting stability of the energy storage module 10; in addition, in the first position, the two support plates 310 can also cooperate to clamp the two sides of the energy storage module 10 along the third direction 3, which can further improve the stability of the energy storage module 10 during hoisting.
[0062] In another embodiment of this application, the tray 310 has a connecting end 311 and a supporting end 312. The connecting end 311 is connected to the second drive assembly 320. Specifically, the connecting end 311 is slidably connected to the second mounting plate 325 in the second drive assembly 320 and connected to the fourth drive end. The fourth drive member drives the connecting end 311 to slide relative to the second mounting plate 325 along the second direction 2. The supporting end 312 is located at the bottom of the tray 310 along the second direction 2 and is used to cooperate with the energy storage module 10. In this design, the pallet 310 has three positions. In the first position, the support end 312 overlaps with the energy storage module 10 in the third direction 3, and the support end 312 abuts against the bottom of the energy storage module 10 along the second direction 2. In the second position, the support end 312 is offset from the energy storage module 10 in the third direction 3, and the support end 312 moves above the energy storage module 10. In the third position, the support end 312 moves below the energy storage module 10 along the second direction 2. To achieve these three positions of movement in the height direction, the second drive assembly 320 can be equipped with two cylinders connected end-to-end in the height direction of the energy storage module 10, or it can be equipped with an electric cylinder or other device that can achieve suspension at any position. With the above structure, when the hoisting equipment 20 needs to grab the energy storage module 10, the support end 312 of the pallet 310 is initially in the first position, that is, fully retracted upwards, higher than the top of the energy storage module 10 along the second direction 2. After the lifting device 100 lifts the energy storage module 10, the second drive component 320 first drives the support end 312 downward to the third position, so that it is completely lower than the bottom of the energy storage module 10 along the second direction 2. Then the second drive component 320 drives the support end 312 upward to the second position, so that it abuts against the bottom of the energy storage module 10. This can prevent the support end 312 from moving directly to the second position and interfering with the corners of the energy storage module 10, thus eliminating the possibility of damage to the energy storage module 10.
