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 related art, the first and second parts of a split-type power supply are usually fixedly connected by bolts. Although this can ensure the stability of the connection between the two parts, it also has the problem of poor disassembly and assembly convenience. Utility Model Content

[0004] In view of this, the present application provides an energy storage device that can be easily assembled.

[0005] One embodiment of the present application provides an energy storage device. The energy storage device includes a first split body and a second split body. The first split body is provided with a first fastener and a first locking member. The second split body is provided with a second fastener and a second locking member. The first fastener is configured to align and engage with the second fastener to enable the first split body and the second split body to be detachably connected. The first locking member is configured to lock with the second locking member and restrict the separation of the first fastener and the second fastener to ensure a fixed connection between the first split body and the second split body.

[0006] In the above embodiment, during the assembly process of the energy storage device, the first fastener and the second fastener are engaged with each other to preliminarily align the first and second split bodies and flexibly connect them, so as to facilitate subsequent more accurate alignment and locking connection; the first lock member and the second lock member are engaged with each other to align the first and second split bodies for a second time. Moreover, the first lock member and the second lock member are locked with each other, which can be used to connect the first and second split bodies on the one hand, and on the other hand, can constrain the fastening connection relationship between the first fastener and the second fastener, thereby achieving double locking between the first and second split bodies. The secondary alignment and double locking are beneficial to improving the speed of energy storage device assembly while improving the stability of energy storage device assembly.

[0007] In some embodiments of the present application, the first locking element is further configured to release the lock with the second locking element and release the constraints on the first fastener and the second fastener, so that the first and second parts are restored to a detachable and movable connection state.

[0008] In the above embodiment, by releasing the first locking member and the second locking member, the first fastener and the second fastener can move relative to each other, thereby allowing the first and second split bodies to move relative to each other, thereby allowing the first and second split bodies to separate. The first locking member and the second locking member can switch between locking and releasing, allowing the first and second split bodies to be both fixedly connected and separated from each other, thereby enabling multiple reassembly and use.

[0009] In some embodiments of the present application, when the first fastener and the second fastener are aligned and fastened, the first fastener and the second fastener can rotate relative to each other within a set angle range to enable the first and second sub-members to rotate and mate. When the first fastener and the second fastener rotate relative to each other beyond the set angle range, the first fastener and the second fastener separate to separate the first and second sub-members.

[0010] In the above-described embodiment, the first and second fasteners rotate in conjunction, thereby both constraining the relative positions of the first and second sub-sections and enabling relative movement of the first and second sub-sections. When the first and second locking members are brought closer together or when the first and second sub-sections are separated, there is no need to determine the relative movement path and direction of the first and second sub-sections, thereby simplifying the assembly and separation operations of the first and second sub-sections. Furthermore, after the first and second fasteners rotate relative to each other beyond a set angle range, they automatically separate, separating the first and second sub-sections from each other, thereby simplifying the separation operation of the first and second sub-sections.

[0011] In some embodiments of the present application, when the first split body and the second split body rotate until the first locking element abuts the second locking element, at least one of the first locking element and the second locking element is configured to receive the force applied by the other and deform so that the first locking element and the second locking element are locked.

[0012] In the above embodiment, after the first and second locking members abut against each other, they deform due to the mutual force exerted on them, thereby locking them together. Therefore, during assembly and connection of the first and second sub-members, the first and second locking members can automatically lock together by utilizing the "impact" generated by the inertia of the relative movement of the first and second sub-members, or by utilizing the weight of one member acting on the other, thereby simplifying the assembly operation of the first and second sub-members.

[0013] In some embodiments of the present application, the second locking element includes a rotating portion, a hooking portion, and a pressing portion. The rotating portion rotates to switch the second locking element to a locked position or an unlocked position. The hooking portion and the pressing portion are respectively connected to the rotating portion. When the second locking element is in the locked position, the hooking portion is hooked with the first locking element so that the second locking element is locked with the first locking element. When the second locking element is in the unlocked position, the hooking portion is separated from the first locking element so that the second locking element is unlocked from the first locking element. The pressing portion is configured to receive the force to drive the rotating portion to rotate so that the second locking element is switched to the unlocked position. The second split body is also provided with an elastic member. The elastic member is connected to the second locking element. The elastic member is configured to provide an elastic force to the second locking element to rotate the second locking element toward the locked position.

[0014] In the above embodiment, the provision of an elastic member causes the second locking member to have a tendency to rotate toward a locked position, thereby maintaining the lock on the connection between the first and second sub-members when the first and second sub-members are connected. During assembly of the first and second sub-members, the first locking member applies a force to the second locking member that overcomes the elastic force of the elastic member, causing the second locking member to first rotate to an unlocked position, and then to engage with the first locking member via the hooking portion to complete the locking. During separation of the first and second sub-members, the pressing portion is pressed to cause the second locking member to rotate to an unlocked position, thereby releasing the lock between the first and second sub-members and facilitating separation of the first and second sub-members.

[0015] In some embodiments of the present application, the hooking portion is provided with an inclined surface. The inclined surface is located on the side of the hooking portion facing the first locking element. The inclined surface is configured such that when the first and second sub-members rotate toward each other, the first locking element abuts the inclined surface and pushes the second locking element toward the unlocked position.

[0016] In the above embodiment, the first locking member abuts against the hooking portion via the inclined surface to apply a force to the second locking member. The inclined surface guides the first locking member to facilitate pushing the second locking member, thereby simplifying the steps of locking the first and second locking members.

[0017] In some embodiments of the present application, the pressing portion is provided with a pressing surface. The pressing surface is disposed toward the first sub-body in a direction from the second sub-body to the first sub-body. The pressing surface is configured to receive a force to rotate the rotating portion and rotate the second locking element to the unlocked position.

[0018] In the above embodiment, the pressing surface faces the first split body. When a force is applied to the pressing surface to rotate the second lock element toward the unlocked position, the direction of the force is away from the first split body, that is, the direction in which the second split body needs to be separated from the first split body is roughly consistent, so that the operational logic of releasing the lock between the first split body and the second lock element is the same as the operational logic of separating the connection between the first split body and the second split body, which is conducive to simplifying the separation operation of the first split body and the second split body.

[0019] In some embodiments of the present application, the first fastener and the first locking member are disposed on opposite sides of the first split body, respectively. The second fastener and the second locking member are disposed on opposite sides of the second split body, respectively. The first fastener is disposed correspondingly to the second fastener, and the first locking member is disposed correspondingly to the second locking member.

[0020] In the above embodiment, the connection position of the first fastener and the second fastener and the connection position of the first lock and the second lock are generally located on opposite sides of the energy storage device. On the one hand, when the first split and the second split are assembled and connected, it is convenient to confirm whether the first fastener and the second fastener are aligned and fastened, and to confirm whether the first lock and the second lock are locked; on the other hand, it is beneficial to prevent the edges of the connection surface of the first split and the second split from warping, thereby improving the connection stability.

[0021] In some embodiments of the present application, a first direction is defined as being parallel to the distribution direction of the first fastener and the first locking element. A second direction is defined as intersecting the first direction. The first split body comprises a first top wall, a first bottom wall, a first front wall, and a first rear wall. The first top wall and the first bottom wall are arranged opposite each other along the second direction. The first front wall and the first rear wall are both connected between the first top wall and the first bottom wall and are arranged opposite each other along the first direction. The first fastener is provided on the first bottom wall and is located on the side adjacent to the first front wall. The first locking element is provided on the first bottom wall and is located on the side adjacent to the first rear wall. The second split body comprises a second top wall, a second bottom wall, a second front wall, and a second rear wall. The second top wall and the second bottom wall are arranged opposite each other along the second direction. The second front wall and the second rear wall are both connected between the second top wall and the second bottom wall and are arranged opposite each other along the first direction. The second fastener is provided on the second top wall and is located on the side adjacent to the second front wall. The second locking element is provided on the second top wall and is located on the side adjacent to the second rear wall.

[0022] In the above embodiment, the first fastener and the second fastener are aligned and fastened on the sides of the first and second front walls to secure the connection between the first and second front walls. The first locking member and the second locking member are locked on the sides of the first and second rear walls to secure the connection between the first and second rear walls. Furthermore, the first fastener and the first locking member are located on the first bottom wall, and the second fastener and the second locking member are located on the second top wall, so that the first fastener, the first locking member, the second fastener, and the second locking member are concealed when the first and second split bodies are connected.

[0023] In some embodiments of the present application, the first fastener and the second fastener have opposite bending directions so that the first fastener and the second fastener are mutually fastened, and the bending directions of the first fastener and the second fastener are both parallel to the distribution direction of the first fastener and the first locking element.

[0024] In the above embodiment, the bending direction of the first fastener and the second fastener is parallel to the distribution direction of the first fastener and the first locking member. When the first fastener and the second fastener are aligned and fastened together, it is convenient to use the first fastener and the second fastener as fulcrums to make the first locking member and the second locking member approach or move away from each other, while maintaining the fastening connection between the first fastener and the second fastener, so as to simplify the assembly and separation operations of the first split and the second split.

[0025] In some embodiments of the present application, the first split body is further provided with a handle, and the handle, the first locking element, and the second locking element are sequentially distributed along a straight line.

[0026] In the above embodiment, when the first and second sub-members are assembled or separated, the handle and the first locking element simultaneously move toward or away from the second locking element. The handle controls the movement of the first sub-member, facilitating the locking and unlocking of the first and second locking elements. Furthermore, the handle and the second locking element are located on either side of the first locking element to minimize the effect of the handle on the locking and unlocking operations of the first and second locking elements.

[0027] In some embodiments of the present application, the first body further comprises a first positioning portion. The first positioning portion is located on a side of the first body facing the second body and is disposed toward the second body. The second body further comprises a second positioning portion. The second positioning portion is located on a side of the second body facing the first body and is disposed toward the first body, and the first positioning portion and the second positioning portion are pluggably mated.

[0028] In the above embodiment, the first positioning portion and the second positioning portion are plugged into each other to position the first body and the second body relative to each other, thereby improving the accuracy of the relative position of the first body and the second body and facilitating accurate alignment of the first locking element and the second locking element when locked.

[0029] In some embodiments of the present application, the first body further comprises a first terminal. The second body further comprises a second terminal. The first terminal is configured to contact the second terminal to electrically connect the first and second bodies. When the first fastener and the second fastener are aligned and engaged, and the first locking member and the second locking member are locked, the first terminal and the second terminal maintain contact. When the first and second bodies are separated, the first and second terminals separate.

[0030] In the above embodiment, the first terminal and the second terminal establish an electrical connection between the first split and the second split through contact, without the need for cables, making the connection convenient, which is conducive to simplifying the structure of the energy storage device and facilitating storage. In addition, the stable mechanical connection between the first split and the second split fixes the relative position between the two, thereby ensuring stable contact between the first terminal and the second terminal, so that the electrical connection between the first split and the second split is stable. The energy storage device simplifies the assembly steps of the energy storage device by establishing a stable mechanical connection between the first split and the second split at the same time, and the first split and the second split move as a whole, facilitating the movement of the energy storage device.

[0031] In some embodiments of the present application, the first terminal is provided with an abutting portion, and the second terminal is provided with an elastic pin. The elastic pin is configured to be elastically retractable. The elastic pin abuts the abutting portion to electrically connect the first terminal and the second terminal.

[0032] In the above embodiment, the elastic needle can elastically expand and contract when electrically connected to the abutment portion, so that the second terminal can adapt to the distance between itself and the first terminal, which is beneficial to eliminating the production errors or assembly errors of the mechanical connection between the first and second parts, and is beneficial to successfully achieving electrical connection between the first and second parts while being mechanically connected.

[0033] In some embodiments of the present application, the first terminal is provided with a plug hole, and the second terminal is provided with a fixing pin, which is inserted into the plug hole to electrically connect the first terminal and the second terminal.

[0034] In the above embodiment, the fixed pin is electrically connected to the socket by plugging, forming a stable mechanical connection between the first terminal and the second terminal, thereby improving the stability of the electrical connection. In addition, the above fixed plug structure helps to simplify the structure of the second terminal, facilitating maintenance and replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] 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.

[0058] 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.

[0059] Furthermore, the terms “first,” “second,” etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0060] 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.

[0061] In the related art, the first and second parts of a split-type power supply are usually fixedly connected by bolts. Although this can ensure the stability of the connection between the two parts, it also has the problem of poor disassembly and assembly convenience.

[0062] An embodiment of the present application provides an energy storage device. The energy storage device includes a first split body and a second split body. The first split body is provided with a first fastener and a first locking member. The second split body is provided with a second fastener and a second locking member. The first fastener is configured to align and engage with the second fastener to enable the first split body and the second split body to be detachably connected. The first locking member is configured to lock with the second locking member and restrict the separation of the first fastener and the second fastener to ensure a fixed connection between the first split body and the second split body.

[0063] During the assembly process of the energy storage device, the first fastener and the second fastener are engaged with each other to initially align the first and second sub-bodies and flexibly connect them, facilitating subsequent more accurate alignment and locking connection. The first locking member and the second locking member are engaged with each other to align and connect the first and second sub-bodies for a second time. Furthermore, the locking of the first locking member and the second locking member can, on the one hand, be used to connect the first and second sub-bodies, and on the other hand, can constrain the fastening connection relationship between the first fastener and the second fastener, achieving double locking between the first and second sub-bodies. The secondary alignment and double locking are beneficial in increasing the speed of energy storage device assembly while improving the stability of the energy storage device assembly.

[0064] 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.

[0065] See also Figure 1 and Figure 2 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.

[0066] See also Figure 1 and Figure 2 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.

[0067] See also Figure 1 and Figure 2 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. Figure 2 The first split body 10 and the second split body 20 are partially separated, rather than completely separated.

[0068] See also Figures 3 to 6 In some embodiments, the first body 10 is provided with a first fastener 11 and a first locking member 12. The second body 20 is provided with a second fastener 21 and a second locking member 22. The first fastener 11 is configured to align and engage with the second fastener 21, so that the first body 10 and the second body 20 are detachably connected. The first locking member 12 is configured to lock with the second locking member 22 and restrict the separation of the first fastener 11 and the second fastener 21, so that the first body 10 and the second body 20 are fixedly connected.

[0069] During the assembly process of the energy storage device 100, the first fastener 11 and the second fastener 21 are interlocked to preliminarily align the first body 10 and the second body 20 and flexibly connect them, so as to facilitate subsequent more accurate alignment and locking connection; the first lock 12 and the second lock 22 are interlocked to align the first body 10 and the second body 20 for a second time. Furthermore, the locking of the first lock 12 and the second lock 22 can, on the one hand, be used to connect the first body 10 and the second body 20, and on the other hand, can constrain the interlocking connection relationship between the first fastener 11 and the second fastener 21, thereby achieving double locking between the first body 10 and the second body 20. The secondary alignment and double locking are beneficial for improving the assembly speed of the energy storage device 100 while also improving the stability of the assembly of the energy storage device 100.

[0070] See also Figure 3 and Figure 4 In some embodiments, the first locking member 12 is further configured to release the lock from the second locking member 22 and release the constraints on the first fastener 11 and the second fastener 21 so that the first split body 10 and the second split body 20 are restored to a detachable and movable connection state.

[0071] By releasing the first locking member 12 and the second locking member 22, the first fastener 11 and the second fastener 21 can move relative to each other, thereby allowing the first and second sub-bodies 10 and 20 to move relative to each other, thereby allowing the first and second sub-bodies 10 and 20 to be separated. The first locking member 12 and the second locking member 22 can switch between locking and releasing, allowing the first and second sub-bodies 10 and 20 to be fixedly connected and separated from each other, thereby enabling multiple reassembly and use.

[0072] In other embodiments, the first locking element 12 is configured to be unable to be released from the second locking element 22 , so that the first split body 10 and the second split body 20 are firmly connected.

[0073] See also Figures 1 to 4 In some embodiments, a first direction is defined to be parallel to the distribution direction of the first fastener 11 and the first locking member 12, a second direction is defined to intersect with the first direction, a third direction is defined to intersect with the first direction, and the first direction, the second direction and the third direction intersect with each other. The first direction is the direction parallel to X in the diagram, the second direction is the direction parallel to Z in the diagram, and the third direction is the direction parallel to Y in the diagram. For ease of reference to the diagram, the first direction is hereinafter indicated by "first direction X", the second direction is hereinafter indicated by "second direction Z", and the third direction is hereinafter indicated by "third direction Y". Exemplarily, the first direction X, the second direction Z and the third direction Y are perpendicular to each other. Exemplarily, Figure 1 The direction opposite to the gravity direction is the direction indicated by the second direction Z.

[0074] See also Figure 1 、 Figure 3 and Figure 5 In some embodiments, the first split body 10 has a first top wall 13, a first bottom wall 14, a first front wall 15, and a first rear wall 16. The first top wall 13 and the first bottom wall 14 are disposed opposite each other along the second direction Z. The first front wall 15 and the first rear wall 16 are both connected between the first top wall 13 and the first bottom wall 14 and are disposed opposite each other along the first direction X.

[0075] See also Figure 2 、 Figure 4 and Figure 6 In some embodiments, the second body 20 includes a second top wall 23, a second bottom wall 24, a second front wall 25, and a second rear wall 26. The second top wall 23 faces the first bottom wall 14. The second top wall 23 and the second bottom wall 24 are disposed opposite each other along the second direction Z. The second front wall 25 and the second rear wall 26 are both connected between the second top wall 23 and the second bottom wall 24 and are disposed opposite each other along the first direction X.

[0076] See also Figures 5 to 8 In some embodiments, the first fastener 11 and the first locking member 12 are disposed on the first bottom wall 14. The second fastener 21 and the second locking member 22 are disposed on the second top wall 23, so that the first fastener 11, the first locking member 12, the second fastener 21, and the second locking member 22 are hidden when the first split body 10 and the second split body 20 are connected.

[0077] See also Figure 2 、 Figure 4 、 Figure 5 and Figure 7 In some embodiments, the first bottom wall 14 is provided with a first accommodating groove 141 adjacent to the first fastener 11 to accommodate the second fastener 21, and is conducive to making the first bottom wall 14 abut against the second top wall 23, thereby sharing the force between the first split body 10 and the second split body 20 borne by the first fastener 11 and the second fastener 21.

[0078] In some embodiments, the first bottom wall 14 is provided with a second receiving groove 142 adjacent to the first locking member 12 to accommodate the second locking member 22. This facilitates contact between the first bottom wall 14 and the second top wall 23, thereby sharing the forces between the first and second sub-bodies 10, 20 borne by the first and second fasteners 11, 21. In other embodiments, the first receiving groove 141 may be omitted, and the second top wall 23 may be provided with a third receiving groove adjacent to the second fastener 21 to accommodate the first fastener 11. In other embodiments, the second receiving groove 142 may be omitted, and the second top wall 23 may be provided with a fourth receiving groove adjacent to the second locking member 22 to accommodate the first locking member 12.

[0079] See also Figure 3 and Figure 4In some embodiments, when the first fastener 11 and the second fastener 21 are aligned and fastened together, the first fastener 11 and the second fastener 21 can rotate relative to each other within a set angle range, so that the first and second parts 10 and 20 can rotate and mate. When the first fastener 11 and the second fastener 21 rotate relative to each other beyond the set angle range, the first fastener 11 and the second fastener 21 separate, so that the first and second parts 10 and 20 are separated. Exemplarily, the axis of relative rotation between the first fastener 11 and the second fastener 21 is parallel to the third direction Y.

[0080] The rotational cooperation between the first fastener 11 and the second fastener 21 not only constrains the relative positions of the first and second sub-bodies 10, 20, but also enables relative movement of the first and second sub-bodies 10, 20. When the first and second locking members 12, 22 are brought closer together or when the first and second sub-bodies 10, 20 are separated from each other, there is no need to find the relative movement path and direction of the first and second sub-bodies 10, 20, thereby simplifying the assembly and separation operations of the first and second sub-bodies 10, 20. Furthermore, after the first and second fasteners 11, 21 rotate relative to each other beyond a set angle range, they automatically separate, separating the first and second sub-bodies 10, 20 from each other. This eliminates the need for a separate step for separating the first and second fasteners 11, 21, thereby simplifying the separation operation of the first and second sub-bodies 10, 20.

[0081] In some embodiments, the minimum value of the set angle range is a first angle, and the maximum value of the set angle range is a second angle. When the first fastener 11 and the second fastener 21 are relatively rotated to the first angle, the first locking member 12 and the second locking member 22 can be locked. When the first fastener 11 and the second fastener 21 are relatively rotated beyond the second angle, the first fastener 11 and the second fastener 21 are separated.

[0082] It is understandable that in some embodiments, the setting angle range and the specific values of the first angle and the second angle are not limited, and are determined by the specific shapes of the first and second parts 10 and 20 and the first and second fasteners 11 and 21.

[0083] See also Figure 3 and Figure 4 In some embodiments, when the first split body 10 and the second split body 20 rotate until the first locking member 12 abuts the second locking member 22, at least one of the first locking member 12 and the second locking member 22 is configured to receive the force applied by the other and deform so that the first locking member 12 and the second locking member 22 are locked.

[0084] After the first locking member 12 and the second locking member 22 abut against each other, they deform due to the mutual force exerted on them, thereby locking them together. Therefore, when assembling and connecting the first and second sub-bodies 10 and 20, the first and second locking members 12 and 22 can be automatically locked together by utilizing the "impact" generated by the inertia of the relative movement of the first and second sub-bodies 10 and 20, or by utilizing the weight of one of the sub-bodies acting on the other, thereby simplifying the assembly operation of the first and second sub-bodies 10 and 20.

[0085] See also Figure 3 and Figure 4 In some embodiments, the second lock element 22 includes a rotating portion 221, a hooking portion 222, and a pressing portion 223. The rotating portion 221 rotates to switch the second lock element 22 to a locked position or an unlocked position. The hooking portion 222 and the pressing portion 223 are respectively connected to the rotating portion 221. When the second lock element 22 is in the locked position, the hooking portion 222 is hooked with the first lock element 12, so that the second lock element 22 is locked with the first lock element 12. When the second lock element 22 is in the unlocked position, the hooking portion 222 is separated from the first lock element 12, so that the second lock element 22 is unlocked from the first lock element 12. The pressing portion 223 is configured to receive the force to drive the rotating portion 221 to rotate, so that the second lock element 22 is switched to the unlocked position. The second split body 20 is also provided with an elastic member 27. The elastic member 27 is connected to the second lock element 22. The elastic member 27 is configured to provide an elastic force to the second locking member 22 to rotate the second locking member 22 toward the locked position. Figure 3 The second locking member 22 is shown in the locked position; Figure 4 The second locking element 22 is shown in the unlocked position.

[0086] The provision of the elastic member 27 allows the second locking member 22 to have a tendency to rotate toward the locked position, thereby maintaining the locked connection between the first and second bodies 10, 20 when they are connected. During assembly of the first and second bodies 10, 20, the first locking member 12 applies a force to the second locking member 22 that overcomes the elastic force of the elastic member 27, causing the second locking member 22 to first rotate to the unlocked position. The second locking member 22 then engages with the first locking member 12 via the hooking portion 222, completing the locking. During separation of the first and second bodies 10, 20, the pressing portion 223 is pressed, causing the second locking member 22 to rotate to the unlocked position, thereby releasing the lock between the first and second locking members 12, 22, and facilitating separation of the first and second bodies 10, 20.

[0087] See also Figure 3 and Figure 4 In some embodiments, the elastic member 27 is a spring or an elastic rubber member. In other embodiments, the elastic member 27 can be an elastic deformation structure of the shell of the second split body 20.

[0088] See also Figure 3 、 Figure 4 、 Figure 6 and Figure 8 In some embodiments, the hooking portion 222 is provided with an inclined surface 2221. The inclined surface 2221 is located on the side of the hooking portion 222 facing the first locking element 12. The inclined surface 2221 is configured such that when the first and second sub-bodies 10, 20 rotate toward each other, the first locking element 12 can abut against the inclined surface 2221 and push the second locking element 22 to rotate toward the unlocked position.

[0089] The first locking member 12 contacts the hooking portion 222 via the inclined surface 2221 to apply force to the second locking member 22. The inclined surface 2221 guides the first locking member 12 to push the second locking member 22, simplifying the steps of locking the first and second locking members 12 and 22.

[0090] It can be understood that in some embodiments, the inclined surface 2221 can be a planar structure or a curved structure.

[0091] See also Figure 3 、 Figure 4 、 Figure 6 and Figure 8 In some embodiments, the pressing portion 223 has a pressing surface 2231. Along the direction from the second sub-body 20 to the first sub-body 10, the pressing surface 2231 is disposed toward the first sub-body 10. The pressing surface 2231 is configured to receive a force to rotate the rotating portion 221 and rotate the second locking element 22 to the unlocked position.

[0092] The pressing surface 2231 is facing the first split body 10. When a force is applied to the pressing surface 2231 to rotate the second lock member 22 to the unlocked position, the direction of the force is away from the first split body 10, that is, the direction in which the second split body 20 needs to be separated from the first split body 10 is roughly consistent, so that the operational logic of releasing the lock of the first lock member 12 and the second lock member 22 is the same as the operational logic of separating the connection between the first split body 10 and the second split body 20, which is conducive to simplifying the separation operation of the first split body 10 and the second split body 20.

[0093] See also Figure 4 In some embodiments, the hooking portion 222 is located on the second top wall 23 to facilitate hooking with the first top wall 13 and the first locking element 12. The pressing portion 223 extends to the second front wall 25 (not shown) or the second rear wall 26 to facilitate a pressing operation when the first split body 10 and the second split body 20 are connected.

[0094] In other embodiments, the second locking element 22 can also be fixed. The second locking element 22 is provided with an elastically deformable structure and is configured to elastically deform in response to the force applied by the first locking element 12, thereby locking the second locking element 22 with the first locking element 12. The elastically deformable structure of the second locking element 22 can be an elastic arm that bends when subjected to force, or a structure that compresses and contracts when subjected to force and recovers when no force is applied. The second locking element 22 utilizes its elastically deformable structure to engage or hook with the first locking element 12.

[0095] In other embodiments, the second locking element 22 can be fixed and the first locking element 12 can be deformable. When the first and second sub-bodies 10 and 20 are assembled and connected, the first locking element 12 is configured to deform in response to the force applied by the second locking element 22, thereby locking the first and second locking elements 12 and 22.

[0096] See also Figure 3 and Figure 4 In some embodiments, the first fastener 11 and the first locking member 12 are disposed on opposite sides of the first split body 10. The second fastener 21 and the second locking member 22 are disposed on opposite sides of the second split body 20. The first fastener 11 is disposed corresponding to the second fastener 21. The first locking member 12 is disposed corresponding to the second locking member 22.

[0097] The connection position of the first fastener 11 and the second fastener 21 and the connection position of the first lock 12 and the second lock 22 are generally located on opposite sides of the energy storage device 100. On the one hand, when the first split body 10 and the second split body 20 are assembled and connected, it is convenient to confirm whether the first fastener 11 and the second fastener 21 are aligned and fastened, and to confirm whether the first lock 12 and the second lock 22 are locked. On the other hand, it is beneficial to prevent the edges of the connection surface of the first split body 10 and the second split body 20 from warping, thereby improving the connection stability.

[0098] See also Figure 3 and Figure 4 In some embodiments, the first fastener 11 is located on the side where the first bottom wall 14 meets the first front wall 15. The first locking member 12 is located on the side where the first bottom wall 14 meets the first rear wall 16. The second fastener 21 is located on the side where the second top wall 23 meets the second front wall 25. The second locking member 22 is located on the side where the second top wall 23 meets the second rear wall 26.

[0099] The first fastener 11 and the second fastener 21 are aligned and fastened together on the sides of the first front wall 15 and the second front wall 25, thereby firmly connecting the first front wall 15 and the second front wall 25. The first locking member 12 and the second locking member 22 are locked together on the sides of the first rear wall 16 and the second rear wall 26, thereby firmly connecting the first rear wall 16 and the second rear wall 26.

[0100] See also Figure 3 and Figure 4 In some embodiments, the first fastener 11 is a curved structure. The second fastener is a curved structure. The bending directions of the first fastener 11 and the second fastener 21 are opposite, so that the first fastener 11 and the second fastener 21 are fastened to each other. And the bending direction of the first fastener 11 and the bending direction of the second fastener 21 are both parallel to the distribution direction of the first fastener 11 and the first locking member 12. Exemplarily, the first fastener 11 extends from the first bottom wall 14 first parallel to the second direction Z and then deviates to extend parallel to the first direction X, and the second fastener 21 extends from the second top wall 23 first parallel to the second direction Z and then deviates to extend parallel to the first direction X. It can be understood that in some embodiments, the first fastener 11 bends toward the first locking member 12, and the second fastener 21 bends away from the second locking member 22.

[0101] The bending direction of the first fastener 11 and the second fastener 21 is parallel to the distribution direction of the first fastener 11 and the first locking member 12. When the first fastener 11 and the second fastener 21 are aligned and fastened together, it is convenient to use the first fastener 11 and the second fastener 21 as a fulcrum to make the first locking member 12 and the second locking member 22 approach or move away from each other, while maintaining the fastening connection between the first fastener 11 and the second fastener 21, so as to simplify the assembly and separation operations of the first split 10 and the second split 20.

[0102] See also Figures 1 to 4 In some embodiments, the first body 10 is further provided with a handle 17. The handle 17, the first locking element 12, and the second locking element 22 are sequentially arranged along a straight line. For example, the handle 17, the first locking element 12, and the second locking element 22 are sequentially arranged parallel to the second direction Z.

[0103] When assembling or separating the first and second parts 10, 20, the handle 17 and the first locking element 12 move simultaneously toward or away from the second locking element 22. The handle 17 controls the movement of the first part 10, facilitating the locking or unlocking of the first and second locking elements 12, 22. Furthermore, the handle 17 and the second locking element 22 are located on either side of the first locking element 12 to minimize the effect of the handle 17 on the locking or unlocking operation of the first and second locking elements 12, 22.

[0104] See also Figures 1 to 4 In some embodiments, the handle 17 is provided on the first top wall 13 and is located on the side connected to the first rear wall 16 so as to form a larger lever arm with the first fastener 11, making it easier to lift the first split body 10 by the handle 17.

[0105] See also Figures 5 to 8In some embodiments, the first body 10 further includes a first positioning portion 18. The first positioning portion 18 is located on a side of the first body 10 facing the second body 20 and is disposed toward the second body 20. The second body 20 further includes a second positioning portion 28. The second positioning portion 28 is located on a side of the second body 20 facing the first body 10 and is disposed toward the first body 10. The first positioning portion 18 and the second positioning portion 28 are pluggably mated.

[0106] The first positioning portion 18 and the second positioning portion 28 are plugged into each other to position the first body 10 and the second body 20 relative to each other, thereby improving the accuracy of the relative positions of the first body 10 and the second body 20 and facilitating accurate alignment of the first locking element 12 and the second locking element 22 when locked.

[0107] See also Figures 5 to 8 In some embodiments, the first positioning portion 18 is disposed on the first bottom wall 14 and is closer to the first locking element 12 than the first fastener 11. The second positioning portion 28 is disposed on the second top wall 23 and is closer to the second locking element 22 than the second fastener 21. The first positioning portion 18 is disposed corresponding to the second positioning portion 28. The first positioning portion 18 and the second positioning portion 28 are disposed closer to the first locking element 12 and the second locking element 22, so that when the first sub-body 10 and the second sub-body 20 approach each other, there is more time to adjust the relative positions, thereby avoiding prematurely restricting the relative positions of the first sub-body 10 and the second sub-body 20 and causing assembly inconvenience.

[0108] In the related art, the first and second parts 10 and 20 need to be electrically connected via cables. However, the cable connection is cumbersome and inconvenient to store. In addition, when moving the energy storage device 100, the different parts need to be moved one by one, which is inconvenient.

[0109] See also Figures 5 to 8 In some embodiments, the first body 10 further includes a first terminal 19. The second body 20 further includes a second terminal 29. The first terminal 19 is configured to contact the second terminal 29 to electrically connect the first body 10 and the second body 20. When the first fastener 11 and the second fastener 21 are aligned and fastened, and the first locking member 12 and the second locking member 22 are locked, the first terminal 19 and the second terminal 29 maintain contact. When the first body 10 and the second body 20 are separated, the first terminal 19 and the second terminal 29 separate. Figure 3 The first terminal 19 and the second terminal 29 are omitted.

[0110] The first terminal 19 and the second terminal 29 establish an electrical connection between the first split 10 and the second split 20 through contact, without the need for cables, making the connection convenient, which helps to simplify the structure of the energy storage device 100 and facilitates storage. In addition, the stable mechanical connection between the first split 10 and the second split 20 fixes the relative position between the two, thereby ensuring stable contact between the first terminal 19 and the second terminal 29, so that the electrical connection between the first split 10 and the second split 20 is stable. The energy storage device 100 simplifies the assembly steps of the energy storage device 100 by establishing a stable mechanical connection between the first split 10 and the second split 20 at the same time, and the first split 10 and the second split 20 move as a whole, which facilitates the movement of the energy storage device 100.

[0111] See also Figure 5 and Figure 6 In some embodiments, the first terminal 19 is provided with an abutting portion 191 . The second terminal 29 is provided with an elastic pin 291 . The elastic pin 291 is configured to be elastically retractable. The elastic pin 291 abuts against the abutting portion 191 to electrically connect the first terminal 19 and the second terminal 29 .

[0112] The elastic needle 291 can elastically expand and contract when electrically connected to the abutment portion 191, so that the second terminal 29 can adapt to the distance between itself and the first terminal 19, which is beneficial to eliminating the production errors or mechanical connection assembly errors of the first split 10 and the second split 20, and is beneficial to successfully achieve electrical connection between the first split 10 and the second split 20 while being mechanically connected.

[0113] See also Figure 7 and Figure 8 In some embodiments, the first terminal 19 is provided with a plug hole. The second terminal 29 is provided with a fixing pin 292. The fixing pin 292 is inserted into the plug hole to electrically connect the first terminal 19 and the second terminal 29.

[0114] The fixing pin 292 is electrically connected to the socket 192 by plugging, forming a stable mechanical connection between the first terminal 19 and the second terminal 29, thereby improving the stability of the electrical connection. In addition, the above-mentioned fixed plug structure is conducive to simplifying the structure of the second terminal 29, facilitating maintenance and replacement.

[0115] See also Figures 1 to 4 In some embodiments, the assembly operation of the energy storage device 100 is:

[0116] Gripping handle 17, align and snap the first fastener 11 and second fastener 21. Rotate first body 10, using the connection between first and second fasteners 11, 21 as the axis, to bring first locking member 12 closer to second locking member 22. As the first locking member 12 moves, it "collides" with second locking member 22, hooking and locking them together. Simultaneously, first terminal 19 and second terminal 29 come into contact, electrically connecting first and second bodies 10, 20, completing assembly.

[0117] See also Figures 1 to 4 In some embodiments, the separation operation of the energy storage device 100 is:

[0118] Pressing the pressing portion 223 of the second locking member 22 releases the first locking member 12 and the second locking member 22. Holding the handle 17, rotate the first body 10 away from the second body 20 until the first fastener 11 and the second fastener 21 have rotated relative to each other beyond the set angle range. This separates the first fastener 11 and the second fastener 21, completing the separation of the first body 10 and the second body 20.

[0119] 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.
