[0052] An energy storage device is a device that can store electrical energy and supply power to electronic devices. In order to supply power to different electronic devices in different occasions, the energy storage device is generally required to have better portability so that it can be carried to the desired location for power supply according to user needs. For example, the energy storage device can be carried outdoors to supply power to cars, sweeping robots and other equipment. Existing energy storage devices usually include a housing and a handle, and the handle is connected to the housing. For example, the two ends of the handle are connected to the top of the housing by two screws respectively. The user can lift the handle to carry the energy storage device. However, in the process of lifting the handle to move the energy storage device, the connection between the handle and the housing will bear the weight of the housing and the energy storage components installed in the housing. Due to the heavy weight of the energy storage device, the handle may be separated from the energy storage device body, and the energy storage device body is at risk of falling off, and the safety and reliability are low.

[0053] To this end, the present application provides an energy storage device, which not only ensures the stability of the handle, but also makes the disassembly and assembly process of the handle simple and quick, thereby reducing costs.

[0054] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0055] like Figures 1 to 3 As shown, the energy storage device provided in the embodiment of the present application includes a housing 10 and a handle 20 .

[0056] The housing 10 includes a first shell 11 and a second shell 12. The first shell 11 and the second shell 12 are connected and cooperate to form a handle cavity (not shown). The first shell 11 and the second shell 12 are located on both sides of the handle cavity along the first direction a. The handle 20 is provided with a gripping space 20a. The handle 20 is provided with a limiting structure 21 on both sides along the first direction a. The handle 20 is arranged in the handle cavity. The limiting structures 21 on both sides cooperate with the first shell 11 and the second shell 12 respectively to fix the handle 20. Among them, the first direction a is the direction from the first shell 11 to the second shell 12.

[0057] It should be noted that, since the first shell 11 and the second shell 12 are connected, the space of the handle cavity formed by them is limited by the first shell 11 and the second shell 12. In this way, when the handle 20 is installed in the handle cavity, the handle 20 will also be limited between the first shell 11 and the second shell 12 by the limiting structures 21 on both sides to prevent the handle 20 from being separated from the handle cavity. Since the limiting structures 21 on both sides of the handle 20 are assembled and disassembled along the first direction a and cooperate with the first shell 11 and the second shell 12, when the user picks up the handle 20, the force direction of the limiting structures 21 on both sides of the handle 20 is not parallel to the first direction a, so the handle 20 is difficult to separate from the shell 10.

[0058] In the energy storage device of the embodiment of the present application, the handle 20 cooperates with the first shell 11 and the second shell 12 respectively through the limiting structures 21 on both sides of the first direction a to be fixed in the handle cavity. Since the first shell 11 and the second shell 12 are connected, the first shell 11 and the second shell 12 can limit the handle 20 in the handle cavity through the limiting structures 21 on both sides of the handle 20. When the user's hand passes through the gripping space 20a to pick up the handle 20, the limiting structures 21 on both sides of the handle 20 are not easy to separate from the first shell 11 and the second shell 12, so that the stability of the handle 20 can be ensured, and the handle 20 is prevented from being separated from the housing 10 during the process of carrying or transporting the energy storage device. In addition, in the process of installing the energy storage device, it is only necessary to assemble the first shell 11 and the second shell 12, and fix the handle 20 between the first shell 11 and the second shell 12 through the limiting structures 21 on both sides. In the process of disassembling the handle 20, it is only necessary to disassemble the first shell 11 and the second shell 12, and the disassembly of the handle 20 can be completed at the same time. Compared with the prior art, the energy storage device of the present application not only ensures the stability of the handle 20, but also makes the disassembly and assembly process of the handle 20 simple and quick, thereby reducing the cost.

[0059] In some embodiments, the limiting structure 21 includes limiting bones, and the first shell 11 and the second shell 12 are both provided with limiting grooves 211, and the limiting bones are embedded in the limiting grooves 211 to fix the handle 20. When installing the handle 20, the limiting bones on both sides of the handle 20 can be respectively embedded in the two limiting grooves 211 along the first direction a; and when disassembling the handle 20, only the first shell 11 and the second shell 12 need to be disassembled, and the limiting bones on both sides of the handle 20 can be separated from the first shell 11 and the second shell 12 along the first direction a. The disassembly and assembly process of the handle 20 is simple and fast, and the cost is reduced. In addition, when the user carries the handle 20, the limiting groove 211 will press against the limiting bones to prevent the limiting bones from being separated from the limiting groove 211, thereby ensuring the stability of the handle 20.

[0060] like Figures 3 to 5 As shown, in some other embodiments, both the first shell 11 and the second shell 12 are provided with a limiting bone (not shown), and the limiting bone is embedded in the limiting groove 211 to fix the handle 20. When installing the handle 20, the limiting bones of the first shell 11 and the second shell 12 can be respectively embedded in the limiting grooves 211 on both sides of the handle 20 along the first direction a; and when removing the handle 20, it is only necessary to remove the first shell 11 and the second shell 12, and the limiting bones of the first shell 11 and the second shell 12 can be separated from the limiting grooves 211 on both sides of the handle 20 along the first direction a. The disassembly and assembly process of the handle 20 is simple and fast, which reduces the cost. In addition, when the user carries the handle 20, the limiting bone will support the limiting groove 211 to prevent the limiting bone from being separated from the limiting groove 211, thereby ensuring the stability of the handle 20.

[0061] like Figure 5 As shown, in some embodiments, the limiting bone is adapted to the limiting groove 211, and both the limiting bone and the limiting groove 211 are extended from the first end 203 to the second end 204 of the handle 20. The limiting bone is adapted to the limiting groove 211, which can ensure that the limiting bone is stably embedded in the limiting groove 211 and is not easily offset, so as to ensure that the handle 20 is stably installed in the handle cavity and is not easily shaken. The limiting bone and the limiting groove 211 are extended from the first end 203 to the second end 204 of the handle 20, so that the length of the limiting bone and the limiting groove 211 is sufficient, and the structural strength of the limiting bone and the limiting groove 211 is ensured to be large, so as to avoid the handle 20 from being separated from the handle cavity due to damage of the limiting bone or the limiting groove 211.

[0062] For example, the first end 203 of the handle 20 is close to the opening at the top of the gripping space 20a, and the second end 204 of the handle 20 is close to the opening at the top of the gripping space 20a. In this way, the length of the limiting bone and the limiting groove 211 can be maximized, and the strength of the structure can also be maximized. For example, the first end 203 of the handle 20 extends to the second end 204 in an arc shape, and the limiting bone and the limiting groove 211 are both arranged along the arc shape extending from the first end 203 to the second end 204 of the handle 20.

[0063] In some embodiments, the limiting structure 21 further includes a limiting column, and the first shell 11 and the second shell 12 are both provided with a limiting hole 212, and the limiting column is embedded in the limiting hole 212 to fix the handle 20. Or, as Figures 3 to 5 As shown, the limiting structure 21 also includes a limiting hole 212. The first shell 11 and the second shell 12 are both provided with a limiting column (not shown), and the limiting column is embedded in the limiting hole 212 to fix the handle 20. The cooperation between the limiting column and the limiting hole 212 further ensures that the handle 20 is stably installed in the handle cavity. In addition, the cooperation between the limiting column and the limiting hole 212 can perform preliminary alignment for the installation of the handle 20, so as to facilitate the subsequent installation and cooperation of other structures, and can further improve the convenience of installing the handle 20.

[0064] like Figure 1 As shown, in some embodiments, the housing 10 is provided with a handle portion 101, the handle portion 101 is provided in at least one of the first housing 11 or the second housing 12, the handle portion 101 is connected to the handle 20, and the structure formed by the handle portion 101 and the handle 20 is used for the user to hold. It should be noted that when the user's hand passes through the holding space 20a and holds the handle 20, the user's hand can also hold the handle portion 101, and the handle 20 is connected to the handle portion 101 in the direction of its force. In this way, the provided handle portion 101 can further prevent the handle 20 from being separated from the handle cavity, thereby ensuring the stability of the handle 20. In addition, since the handle portion 101 is provided in at least one of the first housing 11 or the second housing 12, the stability and reliability of the handle portion 101 can be ensured, further ensuring the stability of the handle 20.

[0065] like Figure 1 As shown, in some embodiments, the housing 10 is formed with handle installation openings 10b located on both sides of the handle portion 101, and the handle installation openings 10b are connected to the handle 20. It should be noted that the openings at both ends of the gripping space 20a of the handle 20 are respectively located at the two handle installation openings 10b, so that when the user's hand passes through the gripping space 20a and grips the handle 20, the handle portion 101 can be gripped at the same time. Further connecting the handle 20 to the handle installation openings 10b can further ensure the stable installation of the handle 20 and prevent it from being separated from the handle cavity. At the same time, the position of the gripping space 20a is further positioned to facilitate the user to grip the handle 20.

[0066] Exemplarily, the handle portion 101 is located at the top edge of the housing 10, and the handle installation openings 10b on both sides of the handle portion 101 are respectively located at the adjacent top surface and side surface of the housing 10. In this way, the openings at both ends of the gripping space 20a of the installed handle 20 are also respectively located at the adjacent top surface and side surface of the housing 10, so that it is convenient for the user to hold the handle 20, making it more convenient for the user to carry the energy storage device.

[0067] like Figure 2 and Figure 3 As shown, in some embodiments, the energy storage device further includes a fastener 50, the fastener 50 connects the first shell 11 and the second shell 12, and the fastener 50 is arranged along the first direction a. The fastener 50 can be used to fasten the first shell 11 and the second shell 12, so as to ensure that the connection between the first shell 11 and the second shell 12 is stable and reliable, and the first shell 11 and the second shell 12 are prevented from being separated in the first direction a, so that the handle 20 is limited in the handle cavity by the limiting structures 21 on both sides of the handle 20.

[0068] like Figure 2 and Figure 4 As shown, in some embodiments, the handle 20 is further provided with a fixing through hole 23a, and the fastener 50 passes through the fixing through hole 23a to connect the handle 20. In this way, the fastener 50 not only connects the first shell 11 and the second shell 12, but also fixes the handle 20 by passing through the fixing through hole 23a, so as to further prevent the handle 20 from being separated from the shell 10, thereby ensuring the stability of the handle 20.

[0069] like Figure 2 and Figure 3 As shown, illustratively, the fastener 50 is located on the side of the handle 20 facing the handle portion 101. In this way, when the user holds the handle 20, the user's hand will hold the handle 20, the handle portion 101 and the fastener 50. By the handle 20, the handle portion 101 and the fastener 50 being jointly stressed, the structural strength of the user's holding position can be increased, ensuring the reliability of carrying or transporting the energy storage device.

[0070] like Figure 2 and Figure 4 As shown, exemplarily, the handle 20 is provided with a protruding annular portion 23, and a fixing through-hole 23a is formed in the annular portion 23. Further, the handle 20 is provided with a plurality of protruding annular portions 23 spaced apart along the first direction a, and the fastener 50 passes through the fixing through-holes 23a of the plurality of annular portions 23 to connect the handle 20, so as to ensure a stable connection between the fastener 50 and the handle 20. For example, the handle 20 is provided with two protruding annular portions 23 spaced apart along the first direction a, and the two annular portions 23 are symmetrically arranged about the center position of the handle 20 along the first direction a.

[0071] like Figure 3 As shown, in some embodiments, the first shell 11 and / or the second shell 12 are provided with a fastening hole 50a, and the fastener 50 passes through the fastening hole 50a to connect the first shell 11 and / or the second shell 12. Through the connection between the fastener 50 and the fastening hole 50a, the fastener 50 and the first shell 11 and / or the second shell 12 are fixedly connected, thereby fastening the first shell 11 and the second shell 12. In this way, when disassembling the first shell 11 and the second shell 12, it is only necessary to connect the fastener 50 and the fastening hole 50a to install the first shell 11 and the second shell 12, and separate the fastener 50 and the fastening hole 50a to disassemble the first shell 11 and the second shell 12. The disassembly process of the first shell 11 and the second shell 12 is simple and quick, which is conducive to the assembly of the handle 20.

[0072] Exemplarily, the first shell 11 is provided with a through hole (not shown), the second shell 12 is provided with a fastening hole 50a, the fastener 50 passes through the through hole to buckle the first shell 11, and is connected to the fastening hole 50a to fasten the first shell 11 and the second shell 12. Alternatively, the second shell 12 is provided with a through hole, the first shell 11 is provided with a fastening hole 50a, the fastener 50 passes through the through hole to buckle the first shell 11, and is connected to the fastening hole 50a to fasten the first shell 11 and the second shell 12. Alternatively, both the first shell 11 and the second shell 12 are provided with a fastening hole 50a, and the two ends of the fastener 50 are respectively connected to the fastening hole 50a of the first shell 11 and the fastening hole 50a of the second shell 12 to fasten the first shell 11 and the second shell 12.

[0073] like Figure 2 As shown, exemplarily, a plurality of fasteners 50 are provided, and the plurality of fasteners 50 connect the first shell 11 and the second shell 12 to fasten the first shell 11 and the second shell 12. For example, the plurality of fasteners 50 are respectively provided at the top edge and the bottom edge of the energy storage device, wherein the fasteners 50 at the top edge can be connected to the handle 20.

[0074] like Figure 2As shown, in some embodiments, the first shell 11 and the second shell 12 may be connected via a buckle structure. For example, a buckle is protruded from the butt edge of the first shell 11 toward the second shell 12, and a slot is provided on the butt edge of the second shell 12 toward the first shell 11, and the buckle is buckled in the slot to connect the first shell 11 and the second shell 12.

[0075] In some embodiments, the fastener 50 includes a metal fastener 50. The metal fastener 50 can ensure the structural strength of the fastener 50, and when the fastener 50 is connected to the first shell 11 and the second shell 12, the connection strength of the first shell 11 and the second shell 12 can be ensured. At the same time, when the fastener 50 is connected to the handle 20, the connection strength of the handle 20 can also be ensured to prevent the handle 20 from being separated from the handle cavity, and the structural strength of the user's grip position can also be increased to ensure the reliability of the transportation of the energy storage device.

[0076] Exemplarily, the fastener 50 is an iron fastener 50, so as to facilitate processing and reduce costs.

[0077] In some embodiments, the fastener 50 includes a screw rod, and the fastener 50 is connected to the fastening hole 50a. It should be noted that the inner wall of the fastening hole 50a is threaded, and the connection between the fastener 50 and the fastening hole 50a is a threaded connection. In this way, when disassembling the first shell 11 and the second shell 12, the fastener 50 can be disassembled and assembled by simply twisting the end of the fastener 50. The disassembly process of the first shell 11 and the second shell 12 is simple and quick, which is conducive to the assembly of the handle 20.

[0078] Exemplarily, one end of the fastener 50 has a thread, and the other end of the fastener 50 is provided with a nut. The fastener 50 can pass through the through-hole of the first shell 11 or the second shell 12, and the first shell 11 or the second shell 12 is fastened by the nut, and the fastening hole 50a of the second shell 12 or the first shell 11 is connected through the threaded end to fasten the first shell 11 and the second shell 12.
