Description

Technical Field

[0001] The utility model relates to the technical field of energy storage, in particular to an energy storage component. Background Art

[0002] In a home energy storage system, the battery module is a core component. The battery module realizes charging and discharging cycles under the coordination of other intelligent hardware and software. The battery module includes multiple stacked batteries.

[0003] In the related art, a plurality of storage batteries are first individually stacked and assembled outside a box, and then fixed inside the box as a whole after being stacked and welded outside the box.

[0004] However, the external assembly of multiple batteries requires many components such as end plates, battery cells, insulating materials, fixing plates or steel belts, collection plates or wiring harnesses, etc., which leads to technical problems such as high production costs of battery modules, large space occupied by batteries, and complicated assembly process. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0006] To this end, the utility model proposes an energy storage component.

[0007] In view of this, the first aspect of the utility model provides an energy storage component, which includes: a box body; a battery pack, the battery pack is arranged in the box body, the battery pack includes a plurality of storage batteries, and the plurality of storage batteries are stacked along a first direction; a clamping mechanism, the clamping mechanism is arranged in the box body, and the clamping mechanism is connected to the box body, the clamping mechanism is at least partially capable of moving along the first direction, and in the first direction, the battery pack is clamped between the inner wall of the box body and the clamping mechanism.

[0008] In this technical solution, an energy storage component is defined, which can be applied to a household photovoltaic system. The energy storage component includes a box and a battery pack.

[0009] The box forms the outer surface of the energy storage component, and the battery pack is arranged inside the box. The box can provide shielding and protection for the battery pack. On the one hand, it prevents the battery pack from being damaged by external impact and external pollutants. On the other hand, the box can form insulation protection to avoid leakage problems in the energy storage component.

[0010] The battery pack includes a plurality of storage batteries, and the plurality of storage batteries are stacked along a first direction to form an array-type battery pack. For example, two battery packs may be provided in the box, each battery pack includes eight storage batteries, the eight storage batteries are stacked in the length direction of the box, and the two battery packs are arranged side by side in the width direction of the box. The battery pack is used to store electrical energy, and the battery pack can be charged and discharged during use to reasonably dispatch electrical energy. Specifically, the storage battery includes a lithium battery.

[0011] On this basis, a clamping mechanism is also provided in the box body, and the clamping mechanism is arranged opposite to the battery pack in a first direction. The clamping mechanism is at least partially able to move along the first direction, that is, the movement direction of the clamping mechanism is consistent with the stacking direction of the multiple batteries. Therefore, the multiple batteries in the battery pack are pressed together by the clamping mechanism contacting the battery pack, so that the multiple batteries are kept in a stacked state, thereby preventing the batteries from loosening or misaligning.

[0012] In the specific assembly process, a plurality of storage batteries are first pre-installed in the box body, and the plurality of storage batteries are arranged along the first direction. In this case, the pressing mechanism is spaced apart from the storage batteries, and there are gaps between the plurality of storage batteries. Thereafter, the pressing mechanism is controlled to move at least partially along the first direction. In this process, the pressing mechanism pushes the storage battery close to the pressing mechanism to squeeze the remaining storage batteries to eliminate the gaps between adjacent storage batteries, so that the plurality of storage batteries can be closely fitted together along the first direction, thereby completing the stacking assembly of the battery pack. After the stacking assembly of the battery pack is completed, the battery assembly clamp is positioned between the inner wall of the box body and the pressing mechanism to make the plurality of storage batteries closely fit.

[0013] It can be seen that the present application provides a clamping mechanism in the box body so that multiple batteries can be stacked and assembled in the box body, eliminating the process of pre-assembly on the outside of the box body, thereby simplifying the assembly process of the battery pack. Moreover, under the pressure of the clamping mechanism, multiple batteries do not need an additional fixed structure for binding, eliminating the end plate, fixed plate or steel belt, and compared with the external assembly scheme, the internal stacking can adjust the wiring in real time, which can reduce the wiring difficulty of the battery pack. Thereby solving the technical problems existing in the related technology of high production cost, large space occupied by batteries, and complicated assembly process, and then achieving the technical effect of optimizing the structure of energy storage components, improving the compactness of the energy storage components, and reducing the production cost of energy storage components.

[0014] In addition, the energy storage assembly provided by the present invention may also have the following additional technical features:

[0015] In some technical solutions of the utility model, optionally, the clamping mechanism includes: a bracket, which is connected to the box body; a driving component, which is arranged on the bracket; a clamping component, which is connected to the driving component, and the driving component is used to drive the clamping component to move along a first direction, and the battery assembly is clamped between the inner wall of the box body and the clamping component.

[0016] In this technical solution, the clamping mechanism includes a bracket, a driving component and a clamping component.

[0017] The bracket is fixed inside the box, the driving component and the clamping component are connected to the bracket, and the driving component is connected to the clamping component. During the assembly process, the driving component can drive the clamping component to move along the first direction on the bracket, thereby contacting and squeezing the battery pack through the clamping component.

[0018] By providing a bracket, on the one hand, the clamping mechanism can be accurately positioned at the predetermined installation position to ensure that the movement direction of the clamping component is consistent with the stacking direction of the battery pack; on the other hand, the bracket can provide positioning and support for the clamping component so that the clamping component can maintain pressure on the battery pack to prevent the battery pack from loosening or disintegrating during use, thereby achieving the technical effect of improving the stability and reliability of the clamping mechanism.

[0019] By setting up a driving component, the user can control the operation of the clamping component by operating the driving component to reduce the difficulty of operating the clamping mechanism. On the other hand, compared with the solution of manually pushing the clamping component, the movement accuracy of the clamping component can be improved by driving the clamping component to move, thereby improving the clamping and positioning reliability of the battery pack.

[0020] In some technical solutions of the utility model, optionally, the driving component includes: a sliding part, which is slidably connected to the bracket, and the sliding part can slide along a second direction, and the second direction is different from the first direction; wherein the clamping part is connected to the bracket, and the clamping part abuts against the sliding part, and the sliding part sliding along the second direction pushes the clamping part to move along the first direction.

[0021] In this technical solution, the driving component includes a sliding part, which is slidably connected to the bracket and can slide on the bracket along a second direction. The second direction is different from the first direction, and the pressing component is partially located on the sliding track of the sliding part. The sliding part sliding along the second direction can push the pressing component away, so that the pressing component moves along the first direction. Moreover, under the reaction force of the battery pack, the pressing component and the sliding part fit tightly, so that the pressing component can continue to provide squeezing force on the battery pack.

[0022] Compared with complex electronically controlled drive structures such as motors, the sliding part has the advantages of low structural complexity, low production cost, and low failure rate. It is suitable for large-scale production of energy storage components and is beneficial to improving the market competitiveness of energy storage components.

[0023] The first direction corresponds to the length direction or the width direction of the box, and the idle space reserved inside the box in these two directions is relatively small. By distinguishing the first direction from the second direction, the user does not need to operate the sliding part in a narrow space, thereby improving the structural compactness of the energy storage assembly on the one hand, and reducing the assembly complexity of the energy storage assembly on the other hand.

[0024] Specifically, the first direction is perpendicular to the second direction, the first direction corresponds to the length direction of the box body, and the second direction corresponds to the opening direction of the box body.

[0025] In some technical solutions of the utility model, optionally, the clamping part includes a first inclined surface, which is inclined relative to the first direction; the sliding part includes a second inclined surface, which is inclined relative to the second direction, the first inclined surface and the second inclined surface are in contact with each other, and the sliding part sliding along the second direction pushes the clamping part to move along the first direction through the second inclined surface and the first inclined surface.

[0026] In this technical solution, a first inclined surface is provided on the pressing component, and the first inclined surface is inclined relative to the first direction. Correspondingly, a second inclined surface is provided on the sliding part, and the second inclined surface is inclined relative to the second direction. The inclination angle of the first inclined surface and the inclination angle of the second inclined surface are complementary to each other, and the first inclined surface and the second inclined surface are tightly attached to each other after assembly.

[0027] On this basis, in the process of driving the sliding part to slide along the second direction, the sliding part squeezes the second inclined surface through the first inclined surface, and the first inclined surface and the second inclined surface maintain a fitting state and move in an offset manner. Under this squeezing action, the clamping component is forced to move in the first direction, thereby squeezing the battery pack through the clamping component moving along the first direction, so that two adjacent batteries in the battery pack are tightly fitted.

[0028] By providing the first inclined surface and the second inclined surface to transmit power, the structural complexity and process complexity of the driving component can be reduced, thereby further reducing the production cost of the energy storage component. In addition, the first inclined surface and the second inclined surface that fit each other have a large contact area and strong stability, which can enable the pressing component to maintain the push on the battery and reduce the possibility of the battery loosening and misalignment.

[0029] In some technical solutions of the utility model, optionally, the bracket includes a screw hole, and the driving component also includes: an adjusting bolt, the adjusting bolt passes through the sliding part, and the adjusting bolt is screwed into the screw hole, and the adjusting bolt extends in the second direction; a first elastic member, the first elastic member connects the sliding part and the bracket, and the first elastic member is located between the sliding part and the bracket.

[0030] In this technical solution, a screw hole is provided on the bracket, and an adjusting bolt passing through the sliding part is correspondingly provided on the sliding part, the adjusting bolt extends in the second direction, and one end of the adjusting bolt passing through the sliding part is screwed into the screw hole. The bolt head or adjusting nut on the adjusting bolt is provided on the side of the sliding part facing away from the bracket, and maintains contact with the sliding part.

[0031] When the adjusting bolt is driven to rotate by the bolt head, the insertion depth of the adjusting bolt in the screw hole increases, and the bolt head moving in the second direction drives the sliding part to slide synchronously in the second direction. Correspondingly, when the sliding part is driven to move by rotating the adjusting nut, the adjusting bolt is fixed in the screw hole, the rotating adjusting nut moves in the second direction along the adjusting bolt, and the adjusting nut moving in the second direction drives the sliding part to slide synchronously in the second direction.

[0032] The adjusting bolt has the advantages of high transmission accuracy and strong transmission stability. By setting the adjusting bolt to drive the sliding part connection, the movement accuracy of the sliding part and the clamping part can be improved, ensuring that the clamping part can provide reliable squeezing force to the battery pack and ensure that the batteries can be stacked tightly together during use. On the other hand, the combined structure of the adjusting bolt and the screw hole has a certain self-locking force. Under the action of this self-locking force, the clamping part can maintain the pressure on the battery pack to prevent the battery pack from loosening and disintegrating, thereby achieving the technical effect of improving the reliability of the clamping mechanism and improving the positioning stability of the battery pack.

[0033] On this basis, a first elastic member is further arranged between the sliding part and the bracket. The first elastic member includes a spring, a rubber column and other structures. During the sliding of the sliding part in the second direction, the first elastic member is compressed and accumulates elastic potential energy. After the adjusting bolt is reversed to remove the pressure on the sliding part, the first elastic member releases the elastic potential energy and lifts up the sliding part, so that the sliding part automatically resets to the initial position, thereby providing convenient conditions for the next battery stacking assembly operation.

[0034] In some technical solutions of the present invention, optionally, one of the sliding part and the bracket is provided with a guide groove, and the other is provided with a convex rib, and the convex rib is inserted into the guide groove.

[0035] In this technical solution, a guide groove is provided on one of the sliding part and the bracket, and the depth direction of the guide groove is consistent with the second direction. Correspondingly, a rib is provided on the other one of the sliding part and the bracket, and the shape and size of the rib are adapted to the guide groove. After assembly, the rib is inserted into the guide groove.

[0036] When the sliding part slides relative to the bracket, the rib slides in the guide groove, and the ribs and guide grooves that cooperate with each other can guide the movement of the sliding part, thereby reducing the deviation between the actual movement trajectory and the predetermined movement trajectory, thereby achieving the technical effect of improving the transmission accuracy and the reliability of the clamping mechanism. On the other hand, the plug-fitting ribs and guide grooves can also limit the sliding part in the horizontal direction to prevent the sliding part from lateral displacement.

[0037] In some technical solutions of the present utility model, optionally, the clamping mechanism further includes: a second elastic member, the second elastic member connects the clamping component and the bracket, and the second elastic member is located between the clamping component and the bracket.

[0038] In this technical solution, a second elastic member is arranged between the clamping part and the bracket. The second elastic member includes a spring, a rubber column and other structures. In the process that the sliding part drives the clamping part to move along the first direction, the second elastic member is stretched and accumulates elastic potential energy. After the adjusting bolt is reversed to remove the pressure on the clamping part, the first elastic member drives the sliding part to reset, and the second elastic member drives the clamping part to reset, so that the clamping part and the sliding part are automatically reset to the initial position, thereby providing convenient conditions for the next battery stacking assembly operation.

[0039] In some technical solutions of the utility model, optionally, the box body includes an opening, and the energy storage assembly further includes: a cover body, the cover body is connected to the box body, and the cover body covers the opening.

[0040] In this technical solution, an opening is provided on the top of the box body, and the battery can be installed into the inner side of the box body through the opening. The assembler or user can also operate the clamping mechanism at the opening.

[0041] On this basis, the energy storage assembly also includes a cover body, which is buckled on the opening and connected to the box body. By setting the cover body, the battery and the clamping mechanism inside the opening can be shielded, thereby providing protection for the battery and the clamping mechanism.

[0042] The cover body is detachably connected, and the provision of a detachable cover body can provide convenient conditions for users to maintain the battery.

[0043] In some technical solutions of the utility model, optionally, the clamping component includes a first limiting hole, the cover body includes a second limiting hole, the clamping component includes a first position, and when the clamping component is in the first position, the first limiting hole and the second limiting hole are opposite to each other, and the energy storage component also includes: a limiting component, and the limiting component is passed through the first limiting hole and the second limiting hole.

[0044] In this technical solution, a first limiting hole is provided on the clamping component, a second limiting hole is provided on the cover body, the clamping component includes a first position, and the first position is a predetermined assembly position of the clamping component. When the clamping component moves to the first position along the first direction, the clamping component can provide sufficient compression force for the battery pack to make multiple batteries fit tightly.

[0045] Among them, when the clamping component is in the first position, the first limiting hole and the second limiting hole are opposite to each other, and the limiting component can be inserted into the first limiting hole and the second limiting hole, so that the clamping component is fixed by the limiting component to avoid misalignment of the clamping component, so that the clamping component can maintain pressure on the battery pack, thereby improving the positioning stability of the battery pack.

[0046] Specifically, the limiting components include screws, bolts, and pins.

[0047] In some technical schemes of the utility model, optionally, the energy storage component also includes: a substrate, the substrate is arranged on the bottom wall of the box, the battery pack and the clamping mechanism are arranged on the substrate; a limiting plate, the limiting plate is arranged on the side wall of the box, and the battery pack is clamped between the limiting plate and the clamping component.

[0048] In this technical solution, the energy storage assembly includes a substrate, which is arranged on the bottom wall of the box, and the battery pack and the clamping mechanism are arranged above the substrate, and the clamping mechanism is connected to the substrate through a fixing member. The substrate can provide support for the battery pack and the clamping mechanism, thereby improving the assembly accuracy of the battery pack.

[0049] On this basis, the energy storage assembly also includes a limit plate, which is in contact with the side wall of the box. When the pressing component is moved to the first position, the battery pack is clamped between the limit plate and the pressing component. By setting the limit plate, the direct structure between the battery pack and the box can be avoided. On the one hand, the box can be prevented from being deformed due to compression. On the other hand, the possibility of battery pack leakage can be reduced by selecting an insulating material to prepare the limit plate.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0066] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0067] Refer to the following Figures 1 to 11 An energy storage assembly according to some embodiments of the present invention is described.

[0068] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the utility model provides an energy storage assembly 100, the energy storage assembly 100 includes: a box 110; a battery pack 120, the battery pack 120 is arranged in the box 110, the battery pack 120 includes a plurality of storage batteries 1202, and the plurality of storage batteries 1202 are arranged along a first direction ( Figure 3 and Figure 6 The battery pack 120 is stacked as shown by the arrow a; a clamping mechanism 130 is disposed in the box body 110, and the clamping mechanism 130 is connected to the box body 110, and the clamping mechanism 130 is at least partially capable of moving along a first direction. In the first direction, the battery pack 120 is clamped between the inner wall of the box body 110 and the clamping mechanism 130.

[0069] In this embodiment, an energy storage assembly 100 is defined, and the energy storage assembly 100 can be applied to a household photovoltaic system. The energy storage assembly 100 includes a box 110 and a battery pack 120 .

[0070] The box 110 forms the outer surface of the energy storage component 100, and the battery pack 120 is arranged inside the box 110. The box 110 can provide shielding and protection for the battery pack 120. On the one hand, it prevents the battery pack 120 from being damaged by external impacts and external pollutants. On the other hand, the box 110 can form insulation protection to prevent the energy storage component 100 from leakage problems.

[0071] The battery pack 120 includes a plurality of storage batteries 1202, and the plurality of storage batteries 1202 are stacked along a first direction to form an array of battery packs 120. For example, two battery packs 120 may be provided in the box 110, each battery pack 120 includes eight storage batteries 1202, and the eight storage batteries 1202 are stacked in the length direction of the box 110, and the two battery packs 120 are arranged side by side in the width direction of the box 110. The battery pack 120 is used to store electrical energy, and the battery pack 120 can be charged and discharged during use to reasonably dispatch electrical energy. Specifically, the storage battery 1202 includes a lithium battery.

[0072] On this basis, a clamping mechanism 130 is further provided in the box body 110. The clamping mechanism 130 is arranged opposite to the battery pack 120 in a first direction. The clamping mechanism 130 is at least partially capable of moving along the first direction, that is, the movement direction of the clamping mechanism 130 is consistent with the stacking direction of the multiple batteries 1202. Therefore, the clamping mechanism 130 that contacts the battery pack 120 presses the multiple batteries 1202 in the battery pack 120 together, so that the multiple batteries 1202 are kept in a stacked state, thereby preventing the batteries 1202 from loosening or misaligning.

[0073] In the specific assembly process, a plurality of storage batteries 1202 are first pre-installed in the box 110, and the plurality of storage batteries 1202 are arranged along the first direction. In this case, the pressing mechanism 130 is spaced from the storage batteries 1202, and there are gaps between the plurality of storage batteries 1202. Thereafter, the pressing mechanism 130 is controlled to move at least partially along the first direction. During this process, the pressing mechanism 130 pushes the storage batteries 1202 close to the pressing mechanism 130 to squeeze the remaining storage batteries 1202, so as to eliminate the gaps between the adjacent storage batteries 1202, so that the plurality of storage batteries 1202 can be closely attached together along the first direction, thereby completing the stacking assembly of the battery pack 120. After the stacking assembly of the battery pack 120 is completed, the battery pack 120 is clamped and positioned between the inner wall of the box 110 and the pressing mechanism 130, so that the plurality of storage batteries 1202 are closely attached.

[0074] It can be seen that the present application sets a clamping mechanism 130 in the box 110, so that multiple batteries 1202 can be stacked and assembled in the box 110, eliminating the process of pre-assembly outside the box 110, thereby simplifying the assembly process of the battery pack 120. In addition, under the pressure of the clamping mechanism 130, multiple batteries 1202 do not need additional fixed structures for binding, eliminating end plates, fixed plates or steel belts, and compared with the external assembly solution, the internal stacking can adjust the wiring in real time, which can reduce the wiring difficulty of the battery pack 120. Thereby solving the technical problems of high production cost, large space occupied by batteries 1202, and complicated assembly process existing in the related technology, and thus achieving the technical effect of optimizing the structure of the energy storage component 100, improving the compactness of the structure of the energy storage component 100, and reducing the production cost of the energy storage component 100.

[0075] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments of the utility model, optionally, the clamping mechanism 130 includes: a bracket 132, the bracket 132 is connected to the box body 110; a driving component 134, the driving component 134 is arranged on the bracket 132; a clamping component 136, the clamping component 136 is connected to the driving component 134, the driving component 134 is used to drive the clamping component 136 to move along the first direction, and the battery pack 120 is clamped between the inner wall of the box body 110 and the clamping component 136.

[0076] In this embodiment, the pressing mechanism 130 includes a bracket 132 , a driving component 134 and a pressing component 136 .

[0077] The bracket 132 is fixed on the inner side of the box body 110 , the driving component 134 and the clamping component 136 are connected to the bracket 132 , and the driving component 134 is connected to the clamping component 136 . During the assembly process, the driving component 134 can drive the clamping component 136 to move along the first direction on the bracket 132 , thereby contacting and squeezing the battery pack 120 through the clamping component 136 .

[0078] By providing the bracket 132, on the one hand, it can ensure that the clamping mechanism 130 is accurately positioned at the predetermined installation position, ensuring that the movement direction of the clamping component 136 is consistent with the stacking direction of the battery pack 120; on the other hand, the bracket 132 can provide positioning and support for the clamping component 136, so that the clamping component 136 can maintain pressure on the battery pack 120, thereby preventing the battery pack 120 from loosening or disintegrating during use, thereby achieving the technical effect of improving the stability and reliability of the clamping mechanism 130.

[0079] By providing the driving component 134, the user can control the operation of the clamping component 136 by operating the driving component 134 to reduce the difficulty of operating the clamping mechanism 130. On the other hand, compared with the solution of manually pushing the clamping component 136, the movement accuracy of the clamping component 136 can be improved by driving the clamping component 136 to move through the driving component 134, thereby improving the clamping and positioning reliability of the battery pack 120.

[0080] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments of the present invention, optionally, the driving component 134 includes: a sliding portion 1342, the sliding portion 1342 is slidably connected to the bracket 132, and the sliding portion 1342 can move along the second direction ( Figure 6 The middle arrow b shows sliding), the second direction is different from the first direction; wherein the clamping component 136 is connected to the bracket 132, and the clamping component 136 abuts against the sliding portion 1342, and the sliding portion 1342 sliding along the second direction pushes the clamping component 136 to move along the first direction.

[0081] In this embodiment, the driving component 134 includes a sliding portion 1342, which is slidably connected to the bracket 132, and the sliding portion 1342 can slide on the bracket 132 along the second direction. The second direction is different from the first direction, and the pressing component 136 is partially located on the sliding track of the sliding portion 1342. The sliding portion 1342 sliding along the second direction can push the pressing component 136 away, so that the pressing component 136 moves along the first direction. In addition, under the reaction force of the battery pack 120, the pressing component 136 and the sliding portion 1342 are tightly fitted, so that the pressing component 136 can continue to provide a squeezing force on the battery pack 120.

[0082] Compared with complex electric control drive structures such as motors, the sliding portion 1342 has the advantages of low structural complexity, low production cost, and low failure rate. It is suitable for large-scale production of the energy storage assembly 100 and is beneficial to improving the market competitiveness of the energy storage assembly 100.

[0083] The first direction corresponds to the length direction or the width direction of the box body 110. The idle space reserved inside the box body 110 in these two directions is relatively small. By distinguishing the first direction from the second direction, the user does not need to operate the sliding part 1342 in a small space, thereby improving the structural compactness of the energy storage assembly 100 on the one hand, and reducing the assembly complexity of the energy storage assembly 100 on the other hand.

[0084] Specifically, the first direction is perpendicular to the second direction, the first direction corresponds to the length direction of the box body 110 , and the second direction corresponds to the direction of the opening 1102 of the box body 110 .

[0085] like Figure 6 , Fig. 9 , Fig.10 and Fig.11 As shown, in some embodiments of the utility model, optionally, the clamping component 136 includes a first inclined surface 1362, which is inclined relative to the first direction; the sliding portion 1342 includes a second inclined surface 13422, which is inclined relative to the second direction, and the first inclined surface 13422 and the second inclined surface 13422 are in contact with each other, and the sliding portion 1342 sliding along the second direction pushes the clamping component 136 to move along the first direction through the second inclined surface 13422 and the first inclined surface 1362.

[0086] In this embodiment, the pressing member 136 is provided with a first inclined surface 1362, which is inclined relative to the first direction. Correspondingly, the sliding portion 1342 is provided with a second inclined surface 13422, which is inclined relative to the second direction. The inclination angle of the first inclined surface 1362 and the inclination angle of the second inclined surface 13422 are complementary to each other, and the first inclined surface 1362 and the second inclined surface 13422 are closely attached to each other after assembly.

[0087] On this basis, in the process of driving the sliding part 1342 to slide along the second direction, the sliding part 1342 squeezes the second inclined surface 13422 through the first inclined surface 1362, and the first inclined surface 1362 and the second inclined surface 13422 maintain a fitted state and move in an offset manner. Under the extrusion action, the clamping component 136 is forced to move in the first direction, thereby squeezing the battery pack 120 through the clamping component 136 moving along the first direction, so that the two adjacent batteries 1202 in the battery pack 120 are tightly fitted.

[0088] By providing the first inclined surface 1362 and the second inclined surface 13422 to transmit power, the structural complexity and process complexity of the driving component 134 can be reduced, thereby further reducing the production cost of the energy storage assembly 100. In addition, the first inclined surface 1362 and the second inclined surface 13422 that fit each other have a large contact area and strong stability, which can enable the pressing component 136 to keep pushing the battery 1202, reducing the possibility of the battery 1202 being loose or misaligned.

[0089] like Figure 8 , Fig. 9 , Fig.10 and Fig.11As shown, in some embodiments of the utility model, optionally, the bracket 132 includes a screw hole, and the driving component 134 also includes: an adjusting bolt 1344, the adjusting bolt 1344 passes through the sliding part 1342, and the adjusting bolt 1344 is screwed into the screw hole, and the adjusting bolt 1344 extends in the second direction; a first elastic member 1346, the first elastic member 1346 connects the sliding part 1342 and the bracket 132, and the first elastic member 1346 is located between the sliding part 1342 and the bracket 132.

[0090] In this embodiment, a screw hole is provided on the bracket 132, and an adjusting bolt 1344 is correspondingly provided on the sliding portion 1342 and passes through the sliding portion 1342. The adjusting bolt 1344 extends in the second direction, and one end of the adjusting bolt 1344 passes through the sliding portion 1342 and is screwed into the screw hole. The bolt head or adjusting nut on the adjusting bolt 1344 is provided on the side of the sliding portion 1342 facing away from the bracket 132, and maintains a contact state with the sliding portion 1342.

[0091] When the adjusting bolt 1344 is driven to rotate by the bolt head, the insertion depth of the adjusting bolt 1344 in the screw hole increases, and the bolt head moving in the second direction drives the sliding part 1342 to slide synchronously in the second direction. Correspondingly, when the sliding part 1342 is driven to move by rotating the adjusting nut, the adjusting bolt 1344 is fixed in the screw hole, the rotating adjusting nut moves in the second direction along the adjusting bolt 1344, and the adjusting nut moving in the second direction drives the sliding part 1342 to slide synchronously in the second direction.

[0092] The adjusting bolt 1344 has the advantages of high transmission accuracy and strong transmission stability. By setting the adjusting bolt 1344 to drive the sliding part 1342 to connect, the movement accuracy of the sliding part 1342 and the pressing part 136 can be improved, ensuring that the pressing part 136 can provide reliable squeezing force to the battery pack 120, and ensuring that the storage batteries 1202 can be tightly stacked together during use. On the other hand, the combined structure of the adjusting bolt 1344 and the screw hole has a certain self-locking force. Under the action of the self-locking force, the pressing part 136 can maintain the pressure on the battery pack 120, preventing the battery pack 120 from loosening and disintegrating, thereby achieving the technical effect of improving the reliability of the pressing mechanism 130 and improving the positioning stability of the battery pack 120.

[0093] On this basis, a first elastic member 1346 is further arranged between the sliding part 1342 and the bracket 132. The first elastic member 1346 includes structures such as a spring and a rubber column. During the sliding of the sliding part 1342 in the second direction, the first elastic member 1346 is compressed and accumulates elastic potential energy. After the adjusting bolt 1344 is reversed to remove the pressure on the sliding part 1342, the first elastic member 1346 releases the elastic potential energy and lifts up the sliding part 1342, so that the sliding part 1342 automatically resets to the initial position, thereby providing convenient conditions for the next battery 1202 stacking assembly operation.

[0094] like Fig. 9 , Fig.10 and Fig.11 As shown, in some embodiments of the present invention, optionally, one of the sliding portion 1342 and the bracket 132 is provided with a guide groove 13424 , and the other is provided with a rib 1322 , and the rib 1322 is inserted into the guide groove 13424 .

[0095] In this embodiment, a guide groove 13424 is provided on one of the sliding portion 1342 and the bracket 132, and the depth direction of the guide groove 13424 is consistent with the second direction. Correspondingly, a rib 1322 is provided on the other one of the sliding portion 1342 and the bracket 132, and the shape and size of the rib 1322 are adapted to the guide groove 13424. After assembly is completed, the rib 1322 is inserted into the guide groove 13424.

[0096] When the sliding part 1342 slides relative to the bracket 132, the rib 1322 slides in the guide groove 13424. The rib 1322 and the guide groove 13424 that cooperate with each other can guide the movement of the sliding part 1342, thereby reducing the deviation between the actual movement trajectory and the predetermined movement trajectory, thereby achieving the technical effect of improving the transmission accuracy and improving the reliability of the clamping mechanism 130. On the other hand, the plug-fitting rib 1322 and the guide groove 13424 can also limit the sliding part 1342 in the horizontal direction to prevent the sliding part 1342 from lateral displacement.

[0097] like Figure 5 and Figure 7 As shown, in some embodiments of the present invention, optionally, the clamping mechanism 130 further includes: a second elastic member 138 , the second elastic member 138 connects the clamping component 136 and the bracket 132 , and the second elastic member 138 is located between the clamping component 136 and the bracket 132 .

[0098] In this embodiment, a second elastic member 138 is arranged between the clamping component 136 and the bracket 132. The second elastic member 138 includes a spring, a rubber column and other structures. In the process that the sliding part 1342 drives the clamping component 136 to move along the first direction, the second elastic member 138 is stretched and accumulates elastic potential energy. After the adjusting bolt 1344 is reversed to remove the pressure on the clamping component 136, the first elastic member 1346 drives the sliding part 1342 to reset, and the second elastic member 138 drives the clamping component 136 to reset, so that the clamping component 136 and the sliding part 1342 are automatically reset to the initial position, thereby providing convenient conditions for the next battery 1202 stacking assembly operation.

[0099] like Figure 1 As shown, in some embodiments of the present invention, optionally, the box body 110 includes an opening 1102 , and the energy storage assembly 100 further includes: a cover body, which is connected to the box body 110 and covers the opening 1102 .

[0100] In this embodiment, an opening 1102 is provided on the top of the box body 110 , and the battery 1202 can be installed into the inner side of the box body 110 through the opening 1102 . The assembler or user can also operate the clamping mechanism 130 at the opening 1102 .

[0101] On this basis, the energy storage assembly 100 also includes a cover body, which is buckled on the opening 1102 and connected to the box body 110. By setting the cover body, the battery 1202 and the clamping mechanism 130 inside the opening 1102 can be shielded, thereby providing protection for the battery 1202 and the clamping mechanism 130.

[0102] The cover is detachably connected, and providing a detachable cover can provide convenient conditions for users to maintain the battery 1202.

[0103] like Figure 1 and Figure 7 As shown, in some embodiments of the present invention, optionally, the clamping component 136 includes a first limiting hole 1364, the cover body includes a second limiting hole, the clamping component 136 includes a first position, and when the clamping component 136 is in the first position, the first limiting hole 1364 and the second limiting hole are opposite, and the energy storage component 100 also includes: a limiting component, which is passed through the first limiting hole 1364 and the second limiting hole.

[0104] In this embodiment, a first limiting hole 1364 is provided on the clamping component 136, and a second limiting hole is provided on the cover body. The clamping component 136 includes a first position, which is a predetermined assembly position of the clamping component 136. When the clamping component 136 moves to the first position along the first direction, the clamping component 136 can provide sufficient compression force for the battery pack 120 to make the multiple batteries 1202 fit tightly.

[0105] Among them, when the clamping component 136 is in the first position, the first limiting hole 1364 and the second limiting hole are opposite to each other, and the limiting component can be inserted into the first limiting hole 1364 and the second limiting hole, so that the clamping component 136 is fixed by the limiting component to avoid the clamping component 136 from being misplaced, so that the clamping component 136 can maintain pressure on the battery pack 120, thereby improving the positioning stability of the battery pack 120.

[0106] Specifically, the limiting components include screws, bolts, and pins.

[0107] like Figure 3 As shown, in some embodiments of the present invention, optionally, the energy storage assembly 100 also includes: a substrate 140, the substrate 140 is arranged on the bottom wall of the box body 110, and the battery pack 120 and the clamping mechanism 130 are arranged on the substrate 140; a limiting plate 150, the limiting plate 150 is arranged on the side wall of the box body 110, and the battery pack 120 is clamped between the limiting plate 150 and the clamping component 136.

[0108] In this embodiment, the energy storage assembly 100 includes a substrate 140, which is disposed on the bottom wall of the box body 110, the battery pack 120 and the clamping mechanism 130 are disposed above the substrate 140, and the clamping mechanism 130 is connected to the substrate 140 via a fixing member 160. The substrate 140 can provide support for the battery pack 120 and the clamping mechanism 130, thereby improving the assembly accuracy of the battery pack 120.

[0109] On this basis, the energy storage assembly 100 further includes a limiting plate 150, which is in contact with the side wall of the box 110. When the pressing component 136 is moved to the first position, the battery pack 120 is clamped between the limiting plate 150 and the pressing component 136. By providing the limiting plate 150, the direct contact between the battery pack 120 and the box 110 can be avoided. On the one hand, the box 110 can be prevented from being deformed due to compression. On the other hand, the possibility of leakage of the battery pack 120 can be reduced by selecting an insulating material to prepare the limiting plate 150.
