Description

Technical Field

[0001] The present application relates to the field of mobile energy storage technology, and in particular to an energy storage device. Background Art

[0002] In recent years, energy storage power supplies have become increasingly popular in scenarios such as camping, outdoor work, and home backup. Existing energy storage power supplies often have split designs, such as a separate host and separate power pack to form a scalable power supply, or a separate inverter and separate battery pack to form a single power supply.

[0003] In the prior art, the first and second parts of a split power supply typically feature a plug-in positioning structure to help constrain the relative position of the first part when stacked on the second part. However, this type of fit requires that the first part be moved in the same direction as the plug-in structure when separating the first and second parts. Otherwise, shear forces between the positioning structures can be generated, hindering the movement of the first part and making operation inconvenient. Utility Model Content

[0004] In view of this, the present application provides an energy storage device to simplify the separation operation of the first split body and the second split body.

[0005] One embodiment of the present application provides an energy storage device. The energy storage device includes a first split and a second split. The first split is provided with a first fastener and a first handle. The second split is provided with a second fastener. The first fastener is configured to be aligned and fastened with the second fastener and to be in arc-surface contact. The first fastener can rotate relative to the second fastener within a set angle range, and after rotating beyond the set angle range, it is separated from the second fastener. The first handle is configured to be driven by a force in a direction away from the second split, driving the first split to rotate in a direction away from the second split, so that the first fastener and the second fastener rotate relative to each other beyond the set angle range and separate, thereby separating the first split and the second split.

[0006] In the above embodiment, the first fastener and the second fastener are aligned and fastened together, so as to constrain the relative positions of the first and second parts. In addition, the first fastener and the second fastener can be rotated and matched. When separating the first and second parts, the first and second parts are rotated relative to each other by moving the handle until the first and second fasteners are rotated to separate and the first and second parts are separated. Therefore, when separating the first and second parts, there is no need to deliberately find the moving direction and path of the first part. The rotational matching structure of the first and second fasteners can guide the movement of the first part, thereby simplifying the separation operation. At the same time, when the first and second fasteners rotate relative to each other, the contact surface is an arc surface, which makes the first and second fasteners rotate more smoothly, thereby reducing the difficulty of controlling the rotation of the first part by the first handle, which is conducive to simplifying the separation operation of the first and second parts.

[0007] In some embodiments of the present application, the first fastener and the second fastener are bent in opposite directions so that the first fastener and the second fastener are fastened to each other, and the first fastener is bent in a direction biased toward the first handle.

[0008] In the above embodiment, the first fastener is bent toward the first handle. When the handle is pulled to separate the first split and the second split, it is convenient to maintain the fastening connection between the first fastener and the second fastener, so that the first split can be separated from the second split through a relatively smooth rotation action, reducing the difficulty of the separation operation of the first split and the second split.

[0009] In some embodiments of the present application, the first fastener and the first handle are respectively arranged on opposite sides of the first sub-body. The first fastener is arranged on the side of the first sub-body facing the second sub-body. The first handle is arranged on the side of the first sub-body facing away from the second sub-body.

[0010] In the above embodiment, the first fastener is located near the second body, facilitating alignment and engagement with the second fastener, thereby quickly and stably establishing a rotational connection between the first and second bodies. The first handle is located away from the second body, preventing manipulation of the first handle from being affected by the second body and facilitating operation of the first handle. Furthermore, the first handle and the first fastener are located on opposite sides of the first body, facilitating increased rotational force when the first handle is used to control the rotation of the first body, thereby conserving the driving force required to rotate the first body.

[0011] In some embodiments of the present application, the second split body is further provided with a second handle. The first handle and the second handle are located on the same side of the energy storage device.

[0012] In the above embodiment, the second handle and the first handle are located on the same side of the energy storage device. When the first split body is rotated by the first handle, the posture of the second split body can be controlled by the second handle to facilitate assembly or separation operations on the first split body and the second split body.

[0013] In some embodiments of the present application, the first fastener includes a first connecting portion and a first support rib. A plurality of first support ribs are provided. Each of the plurality of first support ribs is connected to the first connecting portion. The plurality of first support ribs are spaced apart along the axis of rotation of the first fastener and the second fastener. When the first fastener and the second fastener are aligned and fastened together, the first support rib is configured to abut against the second fastener. Furthermore, the contact surface between the first support rib and the second fastener is an arcuate surface.

[0014] In the above embodiment, the first support ribs arranged at intervals cooperate with the second fastener, which can reduce weight while maintaining the fastening connection between the first fastener and the second fastener. In addition, compared to the first fastener cooperating with the second fastener through a whole surface, multiple first support ribs cooperate with the second fastener through multiple surfaces, which helps to eliminate production errors and assembly errors, so that the first fastener and the second fastener can achieve arc-shaped cooperation at more positions in the direction of the rotation axis, thereby improving rotational stability. At the same time, compared to the first fastener cooperating with the second fastener through a whole surface, the first support ribs arranged at intervals can reduce the contact area between the first fastener and the second fastener, thereby reducing rotational friction and making the rotation smoother.

[0015] In some embodiments of the present application, the second fastener includes a second connecting portion and a second supporting rib, and a plurality of second supporting ribs are provided. The plurality of second supporting ribs are all connected to the second connecting portion, and the plurality of second supporting ribs are arranged at intervals along the axial direction of rotation of the second fastener and the second fastener. When the second fastener and the second fastener are aligned and fastened together, the second supporting rib is configured to abut against the first fastener, and the contact surface between the second supporting rib and the first fastener is an arc surface.

[0016] In the above embodiment, the second support ribs arranged at intervals cooperate with the first fastener, which can reduce weight while maintaining the fastening connection between the first fastener and the second fastener. In addition, compared to the second fastener cooperating with the first fastener through a whole surface, multiple second support ribs cooperate with the first fastener through multiple surfaces, which helps to eliminate production errors and assembly errors, so that the first fastener and the second fastener can achieve arc-shaped cooperation in more positions along the direction of the rotation axis, thereby improving rotational stability. At the same time, compared to the second fastener cooperating with the first fastener through a whole surface, the second support ribs arranged at intervals can reduce the contact area between the first fastener and the second fastener, thereby reducing rotational friction and making rotation smoother.

[0017] In some embodiments of the present application, the first body has a first mounting wall. The second body has a second mounting wall. The first mounting wall and the second mounting wall are disposed opposite each other. The first mounting wall is provided with a receiving groove. The first fastener is a side wall of the receiving groove. The second fastener is protruding from the second mounting wall. The receiving groove is configured to receive the second fastener so that the first mounting wall and the second mounting wall abut against each other.

[0018] In the above embodiment, when the first split body and the second split body are connected, the first split body and the second split body are close to each other and an extrusion force is generated therebetween. The second fastener can be accommodated in the accommodating groove. By making the first assembly wall and the second assembly wall abut against each other, the first assembly wall and the second assembly wall share the extrusion force exerted on the first fastener and the second fastener, thereby protecting the integrity and stability of the first fastener and the second fastener structure.

[0019] In some embodiments of the present application, the first assembly wall further comprises a deformation groove. The deformation groove is spaced apart from the accommodating groove. The first fastener is a side wall of the deformation groove. The first fastener is configured to receive a force from the second fastener and deform toward the deformation groove.

[0020] In the above embodiment, by applying a force to the first fastener, at least part of the structure of the first fastener can be deformed toward the side of the deformation groove, that is, away from the side of the second fastener, so that the first fastener and the second fastener are fully fitted and tightly fitted, so that the first fastener and the second fastener are tightly fastened, so that the first fastener and the second fastener can rotate smoothly and stably.

[0021] In some embodiments of the present application, a first support portion is provided on a side of the first sub-body facing the second sub-body. A second support portion is provided on a side of the second sub-body facing the first sub-body. When the first sub-body rotates relative to the second sub-body, the first support portion is configured to support the second support portion to serve as a fulcrum for the rotation of the first and second sub-bodys. The contact surface between the first support portion and the second support portion is a curved surface and / or the contact surface between the second support portion and the first support portion is a curved surface.

[0022] In the above embodiment, when the first and second sub-members rotate, the first and second support portions mutually support and cooperate to share the pressure between the first and second fasteners. This not only helps to maintain the structural stability of the first and second fasteners, but also helps to reduce friction between the first and second fasteners, thereby making the rotation of the first and second sub-members smoother. Furthermore, at least one of the contact surfaces between the first and second support portions is a curved surface, which enables smooth rotation between the first and second support portions, thereby making the rotation of the first and second sub-members smoother as a whole.

[0023] In some embodiments of the present application, the minimum value of the set angle range is defined as a first angle. The maximum value of the set angle range is defined as a second angle. The first split body is further provided with a first connecting member, and the second split body is further provided with a second connecting member. When the first fastener and the second fastener are rotated relative to each other to a first angle, the first connecting member is configured to be connected to the second connecting member and to constrain the separation of the first fastener and the second fastener so that the first split body and the second split body are fixedly connected. When the first fastener and the second fastener are rotated relative to each other to an angle greater than the second angle, the first fastener and the second fastener are separated so that the first split body is separated from the second split body.

[0024] In the above embodiment, when the first and second fasteners are rotated relative to each other to the minimum allowable angle, the first connecting member and the second connecting member are connected, thereby forming multiple connection relationships between the first and second sub-sections, thereby improving the connection stability between the first and second sub-sections. When the first and second fasteners are rotated relative to each other beyond the maximum allowable angle, the connection between the first and second fasteners is released, thereby releasing the connection between the first and second sub-sections, making the separation operation simple and easy to understand.

[0025] In some embodiments of the present application, the first connector and the second connector can be switched between a locked state and an unlocked state. When the first connector and the second connector are in the locked state, the first connector is configured to maintain connection with the second connector and to constrain the separation of the first fastener and the second fastener. When the first connector and the second connector are in the unlocked state, the first connector is configured to be able to separate from the second connector and release the constraints on the first fastener and the second fastener, so that the first and second sub-bodies return to a detachable rotational connection state.

[0026] In the above embodiment, the first and second connectors are locked to securely connect the first and second connectors, thereby improving the stability of the connection between the first and second subassemblies. Furthermore, the first and second connectors can be unlocked to allow separation of the first and second subassemblies, enabling repeated assembly and separation of the first and second subassemblies, thereby facilitating transportation and storage.

[0044] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0046] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0047] Furthermore, the terms “first,” “second,” etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0048] In recent years, energy storage power supplies have become increasingly popular in scenarios such as camping, outdoor work, and home backup. Existing energy storage power supplies often have split designs, such as a separate host and separate power pack to form a scalable power supply, or a separate inverter and separate battery pack to form a single power supply.

[0049] In the prior art, the first and second parts of a split power supply typically feature a plug-in positioning structure to help constrain the relative position of the first part when stacked on the second part. However, this type of fit requires that the first part be moved in the same direction as the plug-in structure when separating the first and second parts. Otherwise, shear forces between the positioning structures can be generated, hindering the movement of the first part and making operation inconvenient.

[0050] An embodiment of the present application provides an energy storage device. The energy storage device includes a first split and a second split. The first split is provided with a first fastener and a first handle. The second split is provided with a second fastener. The first fastener is configured to be aligned and fastened with the second fastener and to be in arc contact. The first fastener can rotate relative to the second fastener within a set angle range, and after rotating beyond the set angle range, it is separated from the second fastener. The first handle is configured to be driven by a force in a direction away from the second split, driving the first split to rotate in a direction away from the second split, so that the first fastener and the second fastener rotate relative to each other beyond the set angle range and separate, thereby separating the first split and the second split.

[0051] The first fastener and the second fastener are aligned and fastened together, so as to constrain the relative positions of the first and second parts. In addition, the first fastener and the second fastener can rotate and match. Therefore, when separating the first and second parts, the first and second parts can be rotated relative to each other by moving the handle until the first and second fasteners rotate to separate and the first and second parts are separated. Therefore, when separating the first and second parts, there is no need to deliberately find the moving direction and path of the first part. The rotational matching structure of the first and second fasteners can guide the movement of the first part, thereby simplifying the separation operation. At the same time, when the first and second fasteners rotate relative to each other, the contact surface is an arc surface, which makes the first and second fasteners rotate more smoothly, thereby reducing the difficulty of controlling the rotation of the first part through the first handle, which is conducive to simplifying the separation operation of the first and second parts.

[0052] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features of the embodiments may be combined with each other.

[0053] See also Figure 1 One embodiment of the present application provides an energy storage device 100. The energy storage device 100 includes a first body 10 and a second body 20. The first body 10 and the second body 20 cooperate with each other.

[0054] In some embodiments, one of the first split 10 and the second split 20 is an independent host, and the other is an independent power pack, and the energy storage device 100 as a whole forms a design of a capacity-expandable power supply. In some embodiments, one of the first split 10 and the second split 20 is an independent inverter, and the other is an independent battery pack, and the energy storage device 100 as a whole forms a design of a power supply. In some embodiments, one of the first split 10 and the second split 20 is an independent power pack, and the other is also an independent power pack, and the energy storage device 100 as a whole forms a design of a large-capacity power pack. Among them, the host has both an inverter module and a battery module, which can output AC power, and thus can independently supply power to electrical devices; while the power pack only has a battery module, which can only output DC power and cannot independently supply power to electrical devices. It needs to be powered by a device with an inverter module to supply power to the electrical devices, and is therefore usually used as a power expansion device for devices such as the host.

[0055] See also Figure 1 、 Figure 2 and Figure 4 In some embodiments, the first body 10 and the second body 20 can be separated from each other or assembled to be connected to each other. In some embodiments, the first body 10 is stacked on the second body 20 along the direction of gravity. In other embodiments, the first body 10 can be placed side by side with the second body 20 in a direction perpendicular to the direction of gravity. For example, Figure 1 As shown in FIG, the first split body 10 is assembled to the upper side of the second split body 20 along the direction of gravity.

[0056] See also Figure 1 、 Figure 2 and Figure 4 In some embodiments, the first body 10 is provided with a first fastener 11 and a first handle 12. The second body 20 is provided with a second fastener 21. The first fastener 11 is configured to be aligned and fastened with the second fastener 21 and to be in arc contact. The first fastener 11 can rotate relative to the second fastener 21 within a set angle range, and after rotating beyond the set angle range, it is separated from the second fastener 21. The first handle 12 is configured to be driven by a force in a direction away from the second body 20, driving the first body 10 to rotate in a direction away from the second body 20, so that the first fastener 11 and the second fastener 21 rotate relative to each other beyond the set angle range and separate, so as to separate the first body 10 and the second body 20.

[0057] The first fastener 11 and the second fastener 21 are aligned and fastened together, thereby constraining the relative positions of the first and second parts 10, 20. Furthermore, the first fastener 11 and the second fastener 21 can rotate and cooperate. Therefore, when separating the first and second parts 10, 20, the first and second parts 10, 20 can be rotated relative to each other by moving the handle until the first and second fasteners 11, 21 rotate to separate, and the first and second parts 10, 20 are separated. Therefore, when separating the first and second parts 10, 20, there is no need to deliberately find the direction and path of movement of the first part 10. The rotational cooperation structure of the first and second fasteners 11, 21 can guide the movement of the first part 10, thereby simplifying the separation operation. Furthermore, when the first and second fasteners 11, 21 rotate relative to each other, the contact surface is an arc surface, making the rotation of the first and second fasteners 11, 21 smoother, thereby reducing the difficulty of controlling the rotation of the first part 10 via the first handle 12, and thus simplifying the separation operation of the first and second parts 10, 20.

[0058] See also Figure 1 In some embodiments, the first handle 12 and the housing of the first sub-body 10 are integrally formed, which facilitates production and helps to fix the position of the first handle 12 for easy operation. In other embodiments, the first handle 12 is detachably mounted on the housing of the first sub-body 10, saving space occupied by the first sub-body 10.

[0059] See also Figures 2 to 4 In some embodiments, the first fastener 11 is a curved structure. The second fastener 21 is a curved structure. The first fastener 11 and the second fastener 21 are bent in opposite directions so that the first fastener 11 and the second fastener 21 are interlocked. The first fastener 11 is bent in a direction toward the first handle 12.

[0060] The first fastener 11 is bent toward the first handle 12. When the handle is pulled to separate the first split body 10 and the second split body 20, it is convenient to maintain the fastening connection between the first fastener 11 and the second fastener 21, so that the first split body 10 can be separated from the second split body 20 through a relatively smooth rotation action, reducing the difficulty of the separation operation of the first split body 10 and the second split body 20.

[0061] See also Figure 2 In some embodiments, the first fastener 11 is disposed on a side of the first body 10 facing the second body 20 . The first handle 12 is disposed on a side of the first body 10 facing away from the second body 20 .

[0062] The first fastener 11 is positioned close to the second body 20, facilitating alignment and fastening with the second fastener 21, thereby quickly and stably forming a rotational connection between the first body 10 and the second body 20. The first handle 12 is positioned away from the second body 20, preventing the first handle 12 from being affected by the second body 20 when being manipulated, thus facilitating manipulation of the first handle 12.

[0063] In other embodiments, the first handle 12 may be disposed on a side of the first body 10 facing the second body 20 .

[0064] See also Figure 2 、 Figure 5 and Figure 6 In some embodiments, the first fastener 11 and the first handle 12 are respectively disposed on opposite sides of the first split body 10 .

[0065] The first handle 12 and the first fastener 11 are located on opposite sides of the first split body 10 , which is beneficial to increasing the rotation force arm when the first split body 10 is controlled by the first handle 12 to save the driving force for rotating the first split body 10 .

[0066] See also Figure 2 、 Figure 7 and Figure 8 In some embodiments, the second body 20 is further provided with a second handle 22. The second fastener 21 and the second handle 22 are respectively disposed on opposite sides of the second body 20. The first handle 12 and the second handle 22 are located on the same side of the energy storage device 100.

[0067] The second handle 22 and the first handle 12 are located on the same side of the energy storage device 100. When the first split body 10 is rotated by the first handle 12, the posture of the second split body 20 can be controlled by the second handle 22, so as to facilitate the assembly or separation operation of the first split body 10 and the second split body 20.

[0068] See also Figure 8 In some embodiments, the second handle 22 and the housing of the second split body 20 are integrally formed, which facilitates production and helps to fix the position of the second handle 22 for easy operation. In other embodiments, the second handle 22 is detachably mounted on the housing of the second split body 20, saving space occupied by the second split body 20.

[0069] See also Figure 1 and Figure 2 In some embodiments, the second handle 22 and the first handle 12 are arranged in a direction perpendicular to the axis of rotation of the first fastener 11 and the second fastener 21. The movement of separating or approaching the first handle 12 and the second handle 22 is controlled in the opposite direction and is perpendicular to the axis of rotation of the first and second sub-bodies 10 and 20, so that the movement provides more force to drive the first sub-bodies 10 to rotate.

[0070] In some embodiments, the first fastener 11 includes a first connecting portion and a first support rib (not shown). A plurality of first support ribs are provided. The plurality of first support ribs are all connected to the first connecting portion. The plurality of first support ribs are spaced apart along the axis of rotation of the first fastener 11 and the second fastener 21. When the first fastener 11 and the second fastener 21 are aligned and fastened together, the first support rib is configured to abut against the second fastener 21. The contact surface between the first support rib and the second fastener 21 is an arc surface.

[0071] The first support ribs arranged at intervals cooperate with the second fastener 21, which can reduce weight while maintaining the fastening connection between the first fastener 11 and the second fastener 21. In addition, compared with the first fastener 11 cooperating with the second fastener 21 through a whole surface, multiple first support ribs cooperate with the second fastener 21 through multiple surfaces, which is conducive to eliminating production errors and assembly errors, so that the first fastener 11 and the second fastener 21 can achieve arc surface cooperation in more positions in the direction of the rotation axis, thereby improving rotation stability. At the same time, compared with the first fastener 11 cooperating with the second fastener 21 through a whole surface, the first support ribs arranged at intervals can reduce the contact area between the first fastener 11 and the second fastener 21, thereby reducing rotational friction and making rotation smoother.

[0072] See also Figure 2 、 Figure 3 and Figure 7 In some embodiments, the second fastener 21 includes a second connecting portion 211 and a second supporting rib 212. A plurality of second supporting ribs 212 are provided, and the plurality of second supporting ribs 212 are all connected to the second connecting portion 211. The plurality of second supporting ribs 212 are spaced apart along the axial direction of rotation of the second fastener 21 and the second fastener 21. When the second fastener 21 and the second fastener 21 are aligned and fastened together, the second supporting rib 212 is configured to abut against the first fastener 11, and the contact surface between the second supporting rib 212 and the first fastener 11 is an arc surface.

[0073] The second support ribs 212 arranged at intervals cooperate with the first fastener 11, which can reduce weight while maintaining the fastening connection between the first fastener 11 and the second fastener 21. In addition, compared with the second fastener 21 cooperating with the first fastener 11 through a whole surface, multiple second support ribs 212 cooperate with the first fastener 11 through multiple surfaces, which is conducive to eliminating production errors and assembly errors, so that the first fastener 11 and the second fastener 21 can achieve arc surface cooperation in more positions along the direction of the rotation axis, thereby improving rotation stability. At the same time, compared with the second fastener 21 cooperating with the first fastener 11 through a whole surface, the second support ribs 212 arranged at intervals can reduce the contact area between the first fastener 11 and the second fastener 21, thereby reducing rotational friction and making rotation smoother.

[0074] See also Figure 3In some embodiments, the energy storage device 100 is provided with only one of the first support rib and the second support rib 212 at the same time to avoid the first support rib and the second support rib 212 being misaligned and unable to fit together.

[0075] See also Figures 2 to 6 In some embodiments, the first body 10 has a first assembly wall 13. The second body 20 has a second assembly wall 23. The first assembly wall 13 and the second assembly wall 23 are arranged opposite to each other. The first assembly wall 13 is provided with a receiving groove 131. The first fastener 11 is a side wall of the receiving groove 131. The second fastener 21 is protruded from the second assembly wall 23. The receiving groove 131 is configured to receive the second fastener 21 so that the first assembly wall 13 and the second assembly wall 23 abut against each other.

[0076] When the first split body 10 and the second split body 20 are connected, the first split body 10 and the second split body 20 are close to each other and an extrusion force is generated therebetween. The second fastener 21 can be accommodated in the accommodating groove 131. By making the first assembly wall 13 and the second assembly wall 23 abut against each other, the first assembly wall 13 and the second assembly wall 23 share the extrusion force exerted on the first fastener 11 and the second fastener 21, thereby protecting the structural integrity and stability of the first fastener 11 and the second fastener 21.

[0077] See also Figures 2 to 5 In some embodiments, the first assembly wall 13 further comprises a deformation groove 132. The deformation groove 132 is spaced apart from the accommodation groove 131. The first fastener 11 forms a side wall of the deformation groove 132. The first fastener 11 is configured to receive the force of the second fastener 21 and deform toward the deformation groove 132.

[0078] By applying a force to the first fastener 11, at least part of the structure of the first fastener 11 can be deformed toward the side of the deformation groove 132, that is, away from the side of the second fastener 21, so that the first fastener 11 and the second fastener 21 are fully fitted and tightly fitted, so that the first fastener 11 and the second fastener 21 are tightly fastened, so that the first fastener 11 and the second fastener 21 can rotate smoothly and stably.

[0079] See also Figure 3 In some embodiments, the depth of the deformation groove 132 is less than the depth of the accommodating groove 131 to prevent the first fastener 11 from being damaged due to excessive deformation, thereby improving the service life of the first fastener 11 and the second fastener 21 for stable cooperation.

[0080] See also Figure 2 and Figure 3In some embodiments, a first support portion 14 is provided on a side of the first body 10 facing the second body 20. A second support portion 24 is provided on a side of the second body 20 facing the first body 10. When the first body 10 rotates relative to the second body 20, the first support portion 14 and the second support portion 24 are configured to support each other and serve as a rotation fulcrum for the first body 10 and the second body 20. The contact surface between the first support portion 14 and the second support portion 24 is a curved surface and / or the contact surface between the second support portion 24 and the first support portion 14 is a curved surface.

[0081] When the first and second parts 10 and 20 rotate, the first and second support portions 14 and 24 support each other to share the pressure between the first and second fasteners 11 and 21. This not only helps to maintain the structural stability of the first and second fasteners 11 and 21, but also helps to reduce friction between the first and second fasteners 11 and 21, thereby making the rotation of the first and second parts 10 and 20 smoother. In addition, at least one of the contact surfaces between the first and second support portions 14 and 24 is a curved surface, which enables smooth rotation between the first and second support portions 14 and 24, thereby making the rotation of the first and second parts 10 and 20 smoother as a whole.

[0082] See also Figure 1 and Figure 2 In some embodiments, the minimum value of the set angle range is defined as a first angle. The maximum value of the set angle range is defined as a second angle. The first split body 10 is further provided with a first connecting member 15, and the second split body 20 is further provided with a second connecting member 25. When the first fastener 11 and the second fastener 21 are rotated relative to each other to a first angle, the first connecting member 15 is configured to be connected to the second connecting member 25 and to constrain the separation of the first fastener 11 and the second fastener 21 so that the first split body 10 and the second split body 20 are fixedly connected. When the first fastener 11 and the second fastener 21 are rotated relative to each other to an angle greater than the second angle, the first fastener 11 and the second fastener 21 are separated so that the first split body 10 and the second split body 20 are separated.

[0083] When the first fastener 11 and the second fastener 21 rotate relative to each other to the minimum allowable angle, the first connecting member 15 and the second connecting member 25 connect, forming multiple connection relationships between the first and second sub-sections 10 and 20, thereby improving the connection stability between the first and second sub-sections 10 and 20. When the first fastener 11 and the second fastener 21 rotate relative to each other beyond the maximum allowable angle, the connection between the first and second fasteners 11 and 21 is released, thereby releasing the connection between the first and second sub-sections 10 and 20, making the separation operation simple and easy to understand.

[0084] In some embodiments, the first connector 15 and the second connector 25 can be switched to a locked state or an unlocked state. When the first connector 15 and the second connector 25 are in the locked state, the first connector 15 is configured to maintain connection with the second connector 25 and constrain the separation of the first fastener 11 and the second fastener 21. When the first connector 15 and the second connector 25 are in the unlocked state, the first connector 15 is configured to be able to separate from the second connector 25 and release the constraints on the first fastener 11 and the second fastener 21, so that the first split 10 and the second split 20 can be restored to a detachable rotation connection state. Exemplarily, Figure 2 The first connecting member 15 and the second connecting member 25 are shown in a locked state. Figure 4 The first connecting member 15 and the second connecting member 25 are shown in an unlocked state.

[0085] By switching the first connector 15 and the second connector 25 to the locked state, the first connector 15 and the second connector 25 are firmly connected, thereby improving the stability of the connection between the first sub-body 10 and the second sub-body 20. The first connector 15 and the second connector 25 can also be switched to the unlocked state, thereby allowing the first sub-body 10 and the second sub-body 20 to be separated, so that the first sub-body 10 and the second sub-body 20 can be repeatedly assembled and separated, which is convenient for transportation and storage.

[0086] See also Figure 1 and Figure 2 In some embodiments, the separation operation of the energy storage device 100 is:

[0087] Grip the first handle 12 and lift it away from the second body 20 to rotate the first body 10 until the first fastener 11 and the second fastener 21 are separated, completing the separation operation of the first body 10 and the second body 20.

[0088] In addition, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present application and are not intended to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of disclosure of the present application.
