Description

Technical Field

[0001] This application relates to the field of energy storage technology, and more particularly to an energy storage device. Background Technology

[0002] Existing energy storage devices include battery modules that can be pulled out or inserted. When an operator pulls out a battery module, there is a possibility that the battery module may be pulled out at once. Since battery modules are generally large and heavy, there is a risk of the operator being injured by falling objects in this situation. Summary of the Invention

[0003] In view of the above situation, it is necessary to provide an energy storage device that can reduce the possibility of the battery module being dragged out at once, which helps to reduce the risk of the operator being injured by falling objects.

[0004] This application provides an energy storage device, including a cabinet, a battery module, and a blocking member. The cabinet has an opening, the battery module is configured to be movable out of the cabinet in a first direction, the battery module has a limiting portion, and the blocking member is disposed in the cabinet through the opening and movable in a second direction perpendicular to the first direction. The blocking member includes a blocking portion and an operating portion, the operating portion protruding from the outside of the cabinet, and the blocking portion located on the inside of the cabinet. The blocking portion is disposed on the movement path of the limiting portion in the first direction, and the operating portion is configured to drive the blocking portion to move in the second direction, so that the blocking portion moves away from the movement path of the limiting portion in the first direction.

[0005] During the process of the operator moving the battery module out of the cabinet along the first direction, because the blocking part is located on the movement path of the limiting part along the first direction, when the limiting part contacts the blocking part, the battery module is restricted from continuing to move out along the first direction. In this situation, it can remind the operator to prepare for the battery module to be completely removed. Subsequently, the operator can use the operating part to move the blocking part along the second direction, so that the blocking part leaves the movement path of the limiting part along the first direction, thereby facilitating the subsequent complete removal of the battery module from the cabinet along the first direction. This reduces the possibility of the battery module being dragged out in one go, which helps to reduce the risk of the operator being injured by falling objects.

[0006] In one or more of the above embodiments, the blocking member includes a connecting portion that connects the operating portion and the blocking portion, and the connecting portion is provided with a through hole. The energy storage device includes a fixing member that passes through the through hole and is fixed to the cabinet, and the blocking member can move relative to the fixing member in a second direction. By having the fixing member pass through the through hole, the possibility of the blocking member's movement path deviating from the second direction can be reduced.

[0007] In one or more of the above embodiments, the distance that the blocking member can move relative to the fixed member in the second direction is D1 mm, and the length of the overlapping portion of the projection of the blocking part and the limiting part in the first direction in the second direction is D2 mm, where D1 > D2. This facilitates the blocking part moving away from the movement path of the limiting part in the first direction along the second direction.

[0008] In one or more of the above embodiments, the second direction is the opposite direction to the direction of gravity. The blocking member is configured such that the blocking part moves away from the limiting part along the first direction, and the blocking member engages with the through hole. In this case, when the operator grasps the operating part and moves the blocking part along the second direction, the operating part can be released. The blocking member will basically not move downward under its own gravity, allowing the operator to concentrate on continuing to move the battery module out along the first direction, which helps to further reduce the risk of the operator being injured by falling objects.

[0009] In one or more of the above embodiments, the cabinet includes a first beam, the first beam includes a front wall, an opening penetrates the front wall, an operating part is movably disposed in the opening and protrudes from the outside of the front wall, a blocking part and a connecting part are disposed on the inside of the front wall, and a fixing member is disposed on the inside of the front wall. In this case, the front wall can provide a certain degree of shielding for the blocking part, which helps to reduce the possibility of damage to the blocking part. Furthermore, it facilitates the operator to grasp the operating part and move the blocking part along the second direction.

[0010] In one or more of the above embodiments, the cabinet includes a first beam, and the battery module extends beyond the front wall along a first direction. In this case, there is a gap between the first beam and the portion of the battery module extending beyond the first beam. When the contact between the limiting part and the blocking part restricts the battery module from continuing to move out along the first direction, the operator can use this gap to move the operating part to drive the blocking part along a second direction, causing the blocking part to leave the movement path of the limiting part along the first direction. This is beneficial for making full use of the space of the energy storage device and improving the convenience of operation.

[0011] In one or more of the above embodiments, the cabinet includes a first beam, and the battery module is provided with a mounting part, which is detachably locked to the first beam. In this case, when the mounting part is locked to the first beam, the possibility of unintended movement of the battery module without being removed by the operator can be reduced, which is beneficial to improving the stability of the energy storage device.

[0012] In one or more of the above embodiments, the cabinet includes a first beam and a support member, the support member being fixed to the first beam, and the battery module being positioned above the support member along the direction of gravity. During the process of the operator moving the battery module out of the cabinet along the first direction, the supporting effect of the support member helps to further reduce the risk of the operator being injured by falling objects.

[0013] In one or more of the above embodiments, the support member includes a first part and a second part, the second part being connected to the first part. The battery module is positioned above the first part along the direction of gravity, and the second part is located on one side of the battery module along a third direction, which is perpendicular to both the first direction and the direction of gravity. During the process of the operator moving the battery module out of the cabinet along the first direction, the second part reduces the possibility of the battery module's movement path deviating from the first direction, thus improving the accuracy of limiting the battery module's continued movement along the first direction through contact between the limiting part and the blocking part.

[0014] In one or more of the above embodiments, the cabinet includes a first beam, which includes a front wall, a side wall, and a rear wall. The front wall and the rear wall are spaced apart along a first direction, and the side wall connects one end of the front wall and the rear wall along a third direction. The other ends of the front wall and the rear wall along the third direction are separate. Along the third direction, the front wall extends beyond the rear wall, and the third direction is perpendicular to the first direction and the direction of gravity. In this case, it is convenient to assemble the blocking member to the first beam through the open structure, reducing the obstruction of the blocking member by the rear wall.

[0015] In one or more of the above embodiments, the limiting part includes a first surface, a second surface, and a third surface. The first surface and the second surface are arranged sequentially along a first direction, and the third surface connects the first surface and the second surface. Along the first direction, the projection of the first surface is separate from the projection of the blocking part, the projection of the second surface overlaps with the projection of the blocking part, and the third surface and the first direction form an acute angle. During the process of the operator moving the battery module into the cabinet in the opposite direction to the first direction, the first surface is closer to the blocking part than the second surface. Since the projections of the first surface and the blocking part along the first direction are separate and the third surface connects the first and second surfaces, the blocking part abuts against the third surface. In this case, the third surface can guide the blocking part to move along the second direction, thereby avoiding the limiting part. This reduces the step required for the operator to separately grasp the operating part to make the blocking part avoid the limiting part, which is beneficial to improving the convenience of moving the battery module into the cabinet.

[0016] In one or more of the above embodiments, along the first direction, the battery module includes a bottom surface and a top surface arranged sequentially, the distance between the top surface and the bottom surface is L1, and the distance between the limiting part and the top surface is L2, where 1 / 3 ≤ L1 / L2 ≤ 1 / 2. In this case, the distance between the limiting part and the top surface in the first direction is neither too large nor too small, which is beneficial to ensure that the battery module is restricted from further movement only after it has been moved a suitable distance along the first direction, thus further reducing the risk of the operator being injured by falling objects.

[0017] In one or more of the above embodiments, the cabinet has a notch, and the blocking part is observably disposed in the notch. Before the operator moves the battery module out of the cabinet along the first direction, the operator can observe the blocking part in the notch, thereby determining that the blocking part is working properly, which helps to further reduce the risk of the operator being injured by falling objects.

[0018] In one or more of the above embodiments, the blocking member is disposed in the cabinet through the opening and is movable in a direction opposite to the second direction, so that the blocking member can move back and forth multiple times.

[0019] In one or more of the above embodiments, the distance that the blocking member can move relative to the fixing member in the second direction refers to the maximum distance that the operating part can move in the opening in the second direction.

[0020] In one or more of the above embodiments, when the fixing member is located at the lowermost end of the through hole along the second direction, the operating part is located at the uppermost end of the opening along the second direction.

[0021] In one or more of the above embodiments, the second direction is the opposite direction to the direction of gravity, and the frictional force between the blocking member and the fixing member along the second direction is greater than the gravity of the blocking member.

[0022] In one or more of the above embodiments, the support member includes a first part and a second part, with the second part connected to the first part. The cross-section of the support member along the first direction is approximately "L"-shaped.

[0023] In one or more of the above embodiments, the acute angle formed by the third surface and the first direction is greater than 30 degrees and less than 90 degrees, which facilitates the insertion of the battery module.

[0024] In one or more of the above embodiments, the blocking part, the operating part, and the connecting part are integrally arranged. Attached Figure Description

[0037] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0038] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have a component that is centrally located. When a component is considered to be "set" on another component, it can be directly set on the other component or may also have a component that is centrally located.

[0039] Unless otherwise stated, the term "multiple" as used herein refers to two or more.

[0040] The terms “first”, “second”, etc., are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implying the quantity, specific order, or primary and secondary relationship of the indicated technical features.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] It should be understood that the “projection” used in this application is an orthogonal projection of one or two components along a certain direction.

[0043] Embodiments of this application provide an energy storage device, including a cabinet, a battery module, and a blocking member. The cabinet has an opening, the battery module is configured to be movable out of the cabinet along a first direction, the battery module has a limiting portion, and the blocking member is disposed in the cabinet through the opening and movable along a second direction perpendicular to the first direction. The blocking member includes a blocking portion and an operating portion, the operating portion protruding from the outside of the cabinet, and the blocking portion located on the inside of the cabinet. The blocking portion is disposed on the movement path of the limiting portion along the first direction, and the operating portion is configured to drive the blocking portion to move along the second direction, so that the blocking portion moves away from the movement path of the limiting portion along the first direction.

[0044] During the process of the operator moving the battery module out of the cabinet along the first direction, because the blocking part is located on the movement path of the limiting part along the first direction, when the limiting part contacts the blocking part, the battery module is restricted from continuing to move out along the first direction. In this situation, it can remind the operator to prepare for the battery module to be completely removed. Subsequently, the operator can use the operating part to move the blocking part along the second direction, so that the blocking part leaves the movement path of the limiting part along the first direction, thereby facilitating the subsequent complete removal of the battery module from the cabinet along the first direction. This reduces the possibility of the battery module being dragged out in one go, which helps to reduce the risk of the operator being injured by falling objects.

[0045] Some embodiments of this application will now be described with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0046] Please refer to the following: Figures 1 to 3 The embodiments of this application provide an energy storage device 100, including a cabinet 10 and a plurality of battery modules 20. The cabinet 10 is provided with a receiving space 101, and the battery modules 20 are disposed in the receiving space 101 and can be moved out of the cabinet 10 along a first direction X.

[0047] In one embodiment, the energy storage device 100 includes a housing 50 that surrounds the cabinet 10 and the plurality of battery modules 20 to enhance protection for the cabinet 10 and the plurality of battery modules 20. Please refer to [reference needed]. Figure 1The housing 50 includes a front door 51 that faces the operator. Opening the front door 51 allows the battery module 20 to be viewed, so that the operator can move the battery module 20.

[0048] In one embodiment, the cabinet 10 includes a first beam 11 (see...) Figure 3 The first beam 11 extends substantially in the direction of gravity. In one embodiment, the cabinet 10 further includes a second beam (not shown), a third beam (not shown), and a fourth beam (not shown). The third beam and the first beam 11 are spaced apart along a first direction X. The second beam and the first beam 11 are spaced apart along a third direction Z. The fourth beam and the second beam are spaced apart along the first direction X.

[0049] The energy storage device 100 includes a blocking member 30, which is disposed in the cabinet 10 and restricts the movement of the battery module 20 relative to the cabinet 10 along a first direction X. (See also...) Figure 3 The cabinet 10 has an opening 102, and a blocking member 30 is disposed on the cabinet 10 through the opening 102 and movable along the second direction Y. The second direction Y is perpendicular to the first direction X.

[0050] In one embodiment, the first direction X is a horizontal direction, which is perpendicular to the direction of gravity. In another embodiment, the second direction Y is the opposite direction to the direction of gravity.

[0051] Please see Figure 4 The battery module 20 is provided with a limiting part 103. When the battery module 20 moves out along the first direction X, the limiting part 103 moves along the first direction X with the battery module 20. Please refer to [link / reference]. Figure 3 and Figure 7 The blocking member 30 includes a blocking part 31 and an operating part 32. The operating part 32 protrudes from the outside of the cabinet 10, and the blocking part 31 is located on the inside of the cabinet 10. The blocking member 30 can move along the second direction Y, and the operating part 32 and the blocking part 31 can also move along the second direction Y.

[0052] In this application, the outer side refers to the side facing the operator along the first direction X when the current door 51 is open, and the inner side is the side opposite to the outer side. When the current door 51 is open, the outer side is the side that can be directly observed by the operator so that the operator can use the operating unit 32.

[0053] In other examples, the energy storage device 100 does not have a front door 51. The outer side is the side facing the operator along the first direction X, and the inner side is the opposite side. The outer side can be directly observed by the operator so that the operator can use the operating unit 32.

[0054] The blocking part 31 is disposed on the movement path of the limiting part 103 along the first direction X. During the process of the operator moving the battery module 20 out of the cabinet 10 along the first direction X, when the limiting part 103 contacts the blocking part 31, the battery module 20 is restricted from further movement along the first direction X by the blocking part 31. In this situation, it can remind the operator to prepare for the battery module 20 to be completely removed. The operating part 32 is configured to move the blocking part 31 along the second direction Y, so that the blocking part 31 leaves the movement path of the limiting part 103 along the first direction X. When the contact between the limiting part 103 and the blocking part 31 restricts the battery module 20 from further movement along the first direction X, the operator can use the operating part 32 to move the blocking part 31 along the second direction Y, so that the blocking part 31 leaves the movement path of the limiting part 103 along the first direction X, thereby facilitating the subsequent complete removal of the battery module 20 from the cabinet 10 along the first direction X by the operator. This reduces the possibility of the battery module 20 being pulled out at once, thus reducing the risk of the operator being injured by falling objects.

[0055] In one embodiment, the blocking member 30 is disposed on the cabinet 10 through the opening 102 and movable in a direction opposite to the second direction Y, so that the blocking member 30 can move back and forth multiple times.

[0056] In one embodiment, the cabinet 10 is provided with a notch 104, and the blocking part 31 is observably disposed in the notch 104. Before the operator removes the battery module 20 from the cabinet 10 along the first direction X, the operator can determine that the blocking part 31 is working properly by observing it in the notch 104, which helps to further reduce the risk of the operator being injured by falling objects. In one embodiment, after the blocking part 31 leaves the movement path of the restricting part 103 along the first direction X, the blocking part 31 cannot be observed through the notch 104 (see...). Figure 3 ).

[0057] In this application, the energy storage device 100 is provided with a front door 51, and the blocking part 31 is observably provided in the notch 104, meaning that when the front door 51 is opened, the blocking part 31 can be observed through the notch 104. In other examples, the energy storage device 100 is not provided with a front door 51, and the blocking part 31 is directly observable in the notch 104.

[0058] Please see Figure 7 In one embodiment, the blocking member 30 includes a connecting part 33, which connects the operating part 32 and the blocking part 31.

[0059] Please see Figures 8 to 11In one embodiment, the connecting portion 33 is provided with a through hole 331, and the energy storage device 100 includes a fixing member 40, which passes through the through hole 331 and is fixedly disposed on the cabinet 10. The blocking member 30 can move relative to the fixing member 40 along the second direction Y. By having the fixing member 40 pass through the through hole 331, the possibility of the moving path of the blocking member 30 deviating from the second direction Y can be reduced.

[0060] In one embodiment, the fastener 40 passes through the through hole 331 and is fixedly disposed on the first beam 11.

[0061] In one embodiment, the fastener 40 is welded to the front wall 111. In another embodiment, the front wall 111 has a fixing hole 1111, and the fastener 40 is disposed in the fixing hole 1111. This facilitates the fastener 40 being fixedly disposed on the front wall 111. It should be understood that the embodiments listed herein are merely examples of the fastener 40 being fixedly disposed on the front wall 111. The fastener 40 can also be fixedly disposed on the front wall 111 in other ways, including but not limited to snap-fitting, adhesive bonding, etc.

[0062] In one embodiment, the blocking member 30 is movable relative to the fixing member 40 along the second direction Y by a distance D1mm (see...). Figure 2 The length of the overlapping portion of the projection of the blocking part 31 and the limiting part 103 along the first direction X in the second direction Y is D2mm (see...). Figure 8 D1 > D2. This facilitates the movement of the blocking part 31 away from the movement path of the limiting part 103 in the first direction X along the second direction Y.

[0063] In one embodiment, the distance that the blocking member 30 can move relative to the fixing member 40 along the second direction Y refers to the maximum distance that the operating part 32 can move in the opening 102 along the second direction Y.

[0064] In one embodiment, the second direction Y is the opposite direction to the direction of gravity. The blocking member 30 is configured such that the blocking part 31 leaves the movement path of the limiting part 103 along the first direction X, and the blocking member 30 engages with the through hole 331. In this case, when the operator grasps the operating part 32 and moves the blocking part 31 along the second direction Y, the operator can release the operating part 32. The blocking member 30 will not move downward under its own gravity, and the operator can concentrate on continuing to move the battery module 20 along the first direction X, which helps to further reduce the risk of the operator being injured by falling objects. Here, the blocking member 30 engaging with the through hole 331 means that the blocking member 30 is engaged with the fixing member 40 at the through hole 331.

[0065] In one embodiment, when the fixing member 40 is located at the lowermost end of the through hole 331 along the second direction Y ( Figure 9 The blocking member 30 is engaged with the through hole 331. Optionally, when the fixing member 40 is located at the lowermost end of the through hole 331 along the second direction Y (see...), Figure 9The operating part 32 is located at the uppermost end of the opening 102 along the second direction Y (see...). Figure 3 ).

[0066] In one embodiment, the fixing member 40 contacts the wall surface of the through hole 331. In another embodiment, the second direction Y is opposite to the direction of gravity, and the frictional force between the blocking member 30 and the fixing member 40 along the second direction Y is greater than the weight of the blocking member 30. This facilitates the blocking member 30 engaging with the through hole 331 after the blocking part 31 leaves the movement path of the limiting part 103 along the first direction X, reducing the possibility that the blocking member 30 may move under its own weight and stop the limiting part 103 again. It should be understood that the frictional force between the blocking member 30 and the fixing member 40 along the second direction Y refers to the frictional force between the blocking member 30 and the fixing member 40 at the wall surface of the through hole 331.

[0067] In one embodiment, the second direction Y is the opposite direction to the direction of gravity. The through hole 331 is a waist hole, and the length direction of the waist hole is parallel to the second direction Y. The fixing member 40 is a screw, and the fixing member 40 and the through hole 331 are interference-fitted in the width direction of the waist hole. By adjusting the degree of interference fit between the fixing member 40 and the through hole 331, the frictional force between the blocking member 30 and the fixing member 40 along the second direction Y can be easily adjusted, which helps to reduce the possibility that the blocking member 30 will move under its own gravity and stop the limiting part 103 again.

[0068] Please see Figure 5 In one embodiment, the first beam 11 includes a front wall 111, with an opening 102 penetrating through the front wall 111. Please refer to [reference needed]. Figure 3 and Figure 5 The operating part 32 is movably disposed in the opening 102 and exposed on the outside of the front wall 111, while the blocking part 31 is disposed on the inside of the front wall 111. In this configuration, the front wall 111 can provide some protection for the blocking part 31, which helps to reduce the possibility of damage to the blocking part 31. Furthermore, it allows the operator to easily grasp the operating part 32 and move the blocking part 31 along the second direction Y.

[0069] In one embodiment, the connecting portion 33 is disposed on the inner side of the front wall 111. The front wall 111 can provide a certain degree of shielding for the blocking portion 31, which helps to reduce the possibility of damage to the blocking portion 31. In one embodiment, the fixing member 40 is disposed on the inner side of the front wall 111. This facilitates the placement of the connecting portion 33 on the inner side of the front wall 111.

[0070] In one embodiment, a notch 104 is provided on the front wall 111.

[0071] Please see Figure 5In one embodiment, the first beam 11 includes a side wall 112 and a rear wall 113. The rear wall 113 and the front wall 111 are spaced apart along a first direction X. The side wall 112 connects one end of the front wall 111 and the rear wall 113 along a third direction Z. The other ends of the front wall 111 and the rear wall 113 along the third direction Z are separate, meaning that the front wall 111 and the rear wall 113 are not connected, forming an open structure. The third direction Z is perpendicular to the first direction X and the direction of gravity.

[0072] In one embodiment, the sidewall 112 connects the end of the front wall 111 and the rear wall 113 that is furthest from the battery module 20 along the third direction Z.

[0073] In one embodiment, along the third direction Z, the front wall 111 extends beyond the rear wall 113. In this case, it is convenient to assemble the blocking member 30 to the first beam 11 through the open structure, reducing the obstruction of the blocking member 30 by the rear wall 113.

[0074] Please see Figure 3 In one embodiment, the cabinet 10 includes a support member 12, which is fixed to the first beam 11. The battery module 20 is positioned above the support member 12 along the direction of gravity. During the process of the operator removing the battery module 20 from the cabinet 10 along the first direction X, the support provided by the support member 12 helps to further reduce the risk of the operator being injured by falling objects.

[0075] In one embodiment, the support member 12 connects a first beam 11 and a third beam adjacent along a first direction X. In another embodiment, multiple support members 12 are spaced apart along the direction of gravity. This facilitates the spaced arrangement of multiple battery modules 20 along the direction of gravity within the receiving space 101 of the cabinet 10.

[0076] Please see Figure 3 In one embodiment, the support member 12 includes a first portion 121 and a second portion 122, the second portion 122 being connected to the first portion 121. In one embodiment, the cross-section of the support member 12 along the first direction X is approximately "L"-shaped.

[0077] In one embodiment, the battery module 20 is positioned above the first portion 121 along the direction of gravity, and the second portion 122 is located on the side of the battery module 20 along the third direction Z. During the process of the operator moving the battery module 20 out of the cabinet 10 along the first direction X, the second portion 122 reduces the possibility of the battery module 20 deviating from the first direction X, thus improving the accuracy of limiting the battery module 20 from further movement along the first direction X by the contact between the limiting portion 103 and the blocking portion 31.

[0078] In one embodiment, the battery module 20 extends beyond the front wall 111 along the first direction X. In this case, there is a gap between the first beam 11 and the portion of the battery module 20 extending beyond the first beam 11. When the contact between the limiting part 103 and the blocking part 31 restricts the battery module 20 from continuing to move out along the first direction X, the operator can use this gap to move the operating part 32 to move the blocking part 31 along the second direction Y, so that the blocking part 31 leaves the movement path of the limiting part 103 along the first direction X, which is beneficial for making full use of the space of the energy storage device 100 and improving the convenience of operation.

[0079] Please see Figure 4 In one embodiment, the battery module 20 includes a bottom surface 21 and a top surface 22 sequentially disposed along a first direction X. When an operator removes the battery module 20 from the cabinet 10, the top surface 22 is closer to the operator than the bottom surface 21. In one embodiment, the top surface 22 is the side of the battery module 20 with electrode polarity.

[0080] In one embodiment, the top surface 22 of the battery module 20 extends beyond the first beam 11 along the first direction X.

[0081] In one embodiment, referring to 4, the distance between the top surface 22 and the bottom surface 21 along the first direction X is L1, and the distance between the limiting part 103 and the top surface 22 is L2, where 1 / 3 ≤ L1 / L2 ≤ 1 / 2. For example, L1 / L2 can be any value among 1 / 3, 3 / 8, 2 / 5, and 1 / 2. This is beneficial because it restricts the battery module 20 from further movement after it has been moved a suitable distance along the first direction X, further reducing the risk of the operator being injured by falling objects.

[0082] Please see Figure 4 In one embodiment, the battery module 20 includes a first side surface 23 and a second side surface 24 disposed opposite to each other along a third direction Z. The first side surface 23 connects the bottom surface 21 and the top surface 22 on one side along the third direction Z, and the second side surface 24 connects the bottom surface 21 and the top surface 22 on the other side.

[0083] In one embodiment, the limiting portion 103 is disposed on at least one of the first side surface 23 and the second side surface 24. For example, please refer to [reference needed]. Figure 4 and Figure 6 The limiting part 103 is provided on the first side 23.

[0084] Please see Figure 6 In one embodiment, the limiting part 103 includes a first surface 1031 and a second surface 1032, which are arranged sequentially along a first direction X. Before the operator pulls out the battery module 20 along the first direction X and the limiting part 103 contacts the blocking part 31, the second surface 1032 is closer to the blocking part 31 than the first surface 1031.

[0085] Please see Figure 6 In one embodiment, the limiting portion 103 includes a third surface 1033, which connects the first surface 1031 and the second surface 1032. In one embodiment, the third surface 1033 is the side of the limiting portion 103 that is closer to the blocking portion 31 along the second direction Y.

[0086] In one embodiment, the third surface 1033 is inclined downward from the second surface 1032 to the first surface 1031.

[0087] In one embodiment, the first surface 1031 and the third surface 1033 are smoothly connected. This facilitates the easy movement of the battery module 20 into the cabinet 10. The smooth transition connection refers to a rounded corner transition connection.

[0088] In one embodiment, see Figure 2 , Figure 2 The diagram shows the battery module 20 assembled into the cabinet 10, with the blocking part 31 positioned on the movement path of the limiting part 103 along the first direction X. Along the first direction X, the projection of the first surface 1031 is opposite to the projection of the blocking part 31, and the third surface 1033 forms an acute angle θ with the first direction X (see...). Figure 6 During the process of the operator moving the battery module 20 into the cabinet 10 in the opposite direction to the first direction X, the first surface 1031 is closer to the blocking part 31 than the second surface 1032. Since the projection of the first surface 1031 and the blocking part 31 along the first direction X is separate and the third surface 1033 connects the first surface 1031 and the second surface 1032, the blocking part 31 abuts against the third surface 1033. In this case, the third surface 1033 can guide the blocking part 31 to move along the second direction Y, thereby avoiding the restricting part 103. This reduces the step required for the operator to hold the operating part 32 to make the blocking part 31 avoid the restricting part 103, which helps to improve the convenience of moving the battery module 20 into the cabinet 10.

[0089] In one embodiment, the acute angle θ formed by the third surface 1033 and the first direction X is greater than 30 degrees and less than 90 degrees, which facilitates the insertion of the battery module 20. For example, the acute angle θ is any value among 35 degrees, 40 degrees, 45 degrees, 50 degrees, 60 degrees, 70 degrees and 80 degrees.

[0090] In one embodiment, see Figure 2 Along the first direction X, the projection of the second surface 1032 overlaps with the projection of the blocking part 31. This improves the stability of the contact between the second surface 1032 and the blocking part 31, thereby improving the stability of the battery module 20 being restricted from further moving out along the first direction X. This helps reduce the possibility that the battery module 20 might be moved out in one go due to the large force applied by the operator when removing it, thus further reducing the possibility of the operator being injured by falling objects.

[0091] In one embodiment, the battery module 20 is provided with a mounting portion 105 (see [reference]). Figure 4 The mounting portion 105 is detachably locked to the first beam 11. In this case, when the mounting portion 105 is locked to the first beam 11, the possibility of unintended movement of the battery module 20 without being removed by the operator can be reduced, which is beneficial to improving the stability of the energy storage device 100. In one embodiment, the mounting portion 105 is provided on at least one of the first side 23 and the second side 24.

[0092] In one embodiment, the mounting portion 105 is detachably locked to the front wall 111 of the first beam 11, which facilitates the release of the lock between the mounting portion 105 and the first beam 11. For example, the mounting portion 105 can be fixed to the front wall 111 by screws.

[0093] In one embodiment, the mounting portion 105 is disposed on at least one side of the battery module 20 along the third direction Z. It should be understood that the mounting portion 105 is disposed on at least one of the first side 23 and the second side 24.

[0094] In one embodiment, in the first direction X, the mounting portion 105 is closer to the top surface 22 than the limiting portion 103, which allows the battery module 20 to be restricted from further movement only after it has been moved a certain distance along the first direction X, while facilitating the release of the locking between the mounting portion 105 and the first beam 11.

[0095] In one embodiment, the limiting part 103, the blocking part 31, and the mounting part 105 are arranged sequentially along the first direction X. This helps to reduce interference between the mounting part 105 and the blocking part 31 during the process of moving the battery module 20 into or out of the cabinet 10.

[0096] In one embodiment, the blocking member 30 is a metal component. Metal components have high structural strength, which is beneficial to improving the stopping effect of the blocking member 30 on the limiting part 103. The metal component includes, but is not limited to, steel, nickel, and titanium.

[0097] Please see Figure 7 In one embodiment, the blocking part 31 includes a first contact surface 311, which is a surface of the blocking part 31 along a first direction X. The first contact surface 311 is located on the movement path of the limiting part 103 along the first direction X. During the process of the operator removing the battery module 20 from the cabinet 10 along the first direction X, the second surface 1032 contacts the first contact surface 311.

[0098] In one embodiment, the first contact surface 311 is perpendicular to the first direction X.

[0099] Please see Figure 7In one embodiment, the blocking portion 31 includes a second contact surface 312, which is connected to and located below the first contact surface 311. During the process of the operator moving the battery module 20 into the cabinet 10 in the direction opposite to the first direction X, the third surface 1033 contacts the second contact surface 312.

[0100] In one embodiment, the second contact surface 312 is an arc surface, which helps to reduce the wear of the blocking part 31 on the third surface 1033 during the process of moving the battery module 20 into the cabinet 10.

[0101] In one embodiment, the blocking portion 31 is partially bent to form a first contact surface 311 and a second contact surface 312. In another embodiment, the blocking member 30 is a metal component with high toughness, which facilitates the bending of the blocking portion 31.

[0102] In one embodiment, the operating part 32 is generally plate-shaped, and the operator can move the blocking part 31 along the second direction Y by gently moving the operating part 32 along the second direction Y.

[0103] Please see Figure 7 In one embodiment, an insulating layer 321 is provided on the outer periphery of the operating part 32 to facilitate the operator's gripping of the operating part 32. The insulating layer 321 includes, but is not limited to, tape and plastic.

[0104] In one embodiment, the blocking part 31, the operating part 32, and the connecting part 33 are integrally formed. The blocking part 31, the operating part 32, and the connecting part 33 are formed by bending the same metal substrate. This helps to improve the overall structural strength of the blocking member 30.

[0105] The following, combined with Figure 8 and Figure 9 This application describes the process of removing the battery module 20 from the cabinet 10 in some embodiments, in conjunction with... Figure 10 and Figure 11 This application describes how, in some embodiments, the battery module 20 is moved into the cabinet 10.

[0106] As the operator moves the battery module 20 out of the cabinet 10 along the first direction X, the limiting part 103 moves along with the battery module 20, and the second surface 1032 of the limiting part 103 gradually approaches the first contact surface 311 of the blocking part 31 along the first direction X (see...). Figure 8At this point, the blocking part 31 acts as a stop to the limiting part 103, thereby restricting the battery module 20 from being moved further out along the first direction X. This serves as a reminder to the operator to prepare for the battery module 20 to be completely removed. After the operator moves the blocking part 31 along the second direction Y using the operating part 32, causing the blocking part 31 to leave the movement path of the limiting part 103 along the first direction X, the blocking part 31 releases its stopping effect on the limiting part 103. At this point, the battery module 20 can continue to be moved out along the first direction X (see...). Figure 9 (until it is completely removed).

[0107] As the operator moves the battery module 20 into the cabinet 10 in the direction opposite to the first direction X, the limiting part 103 moves along with the battery module 20. The third surface 1033 of the limiting part 103 gradually approaches the second contact surface 312 of the blocking part 31 in the direction opposite to the first direction X (see...). Figure 10 and Figure 11 Because the third surface 1033 is inclined downwards, it guides the blocking part 31 through contact with the second contact surface 312. Thus, as the battery module 20 moves in the opposite direction to the first direction X, the blocking part 31 naturally moves in the second direction Y. At this time, the blocking part 31 does not stop the limiting part 103. After the limiting part 103 has completely passed the notch 104 in the opposite direction to the first direction X, the operator can use the operating part 32 to move the blocking part 31 in the opposite direction to the second direction Y, so that the blocking part 31 is back on the movement path of the limiting part 103 in the first direction X. At this time, the blocking member 30 can again restrict the movement of the battery module 20 relative to the cabinet 10 in the first direction X.

[0108] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and modifications made to the above embodiments within the substantive scope of this application fall within the scope of this application.
