The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] Current energy storage devices usually have handles for easy carrying and transport. In consideration of users' demand for personalized choice of handle color, the handle is usually designed to be detachable from the shell of the energy storage device. However, since the energy storage device is relatively heavy as a whole, a very stable connection is required between the handle and the shell of the energy storage device. In related technologies, there is often a problem of insufficient connection strength between the handle and the shell of the energy storage device, resulting in breakage at the connection between the handle and the shell of the energy storage device. Alternatively, in order to ensure sufficient strength, the handle has a complex structure, resulting in low disassembly and assembly efficiency and inconvenience in disassembly and replacement.

[0042] In view of this, the present application provides a shell structure and energy storage device that can improve both the strength of the handle and the efficiency of the handle's assembly and disassembly. The shell structure includes a top shell and an enclosure. The top shell includes a top shell body and a handle body fixedly connected to the top shell body. The handle body and the top shell body together constitute the main force-bearing structure of the shell structure. The enclosure includes an enclosure body and a handle appearance component. The enclosure body is covered on the outer periphery of the top shell and avoids the handle body. The handle appearance component is detachably connected to the enclosure body and assembled with the handle body to form a handle.

[0043] The present application provides a shell structure in which the handle is formed by combining a handle body and a handle exterior. Firstly, the handle body is fixedly connected to the top shell body to form the main force-bearing structure of the shell structure, which provides the handle body with better structural strength. As the main force-bearing part of the handle, it ensures the structural strength of the handle and reduces the risk of the handle breaking. Secondly, the handle exterior is detachably connected to the shell body, making it easy to remove and replace the handle exterior. As the exterior part of the handle, the user can choose the color of the handle. Therefore, the shell structure forms the handle by combining the handle body and the handle exterior, which not only improves the structural strength of the handle but also improves the efficiency of the handle's assembly and disassembly. This not only facilitates the replacement of the exterior appearance but also ensures the stability of the handle.

[0044] The following is combined with Figures 1 to 8 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0045] like Figures 1 to 2 As shown, some embodiments of the present application provide a housing structure 100 and an energy storage device 200. The energy storage device 200 includes a bottom housing 201, a battery pack 202, and the housing structure 100. The housing structure 100, serving as the upper housing of the energy storage device 200, is connected to the bottom housing 201. A receiving cavity 203 is formed between the housing structure 100 and the bottom housing 201. The receiving cavity 203 is used to accommodate the battery pack 202, etc.

[0046] For example, the energy storage device 200 can be a portable power source for outdoor use, or a home energy storage system for storing energy in a home. Optionally, the energy storage device 200 also includes a circuit board, which is disposed within the accommodating cavity 203. The circuit board can specifically be an inverter circuit board or a BMS (battery management system) circuit board, which can serve as an inverter module to control the charging, discharging, and AC / DC conversion of the battery pack 202, thereby enabling the battery pack 202 to power external devices or enable external devices to charge the battery pack 202.

[0047] In some embodiments, as Figures 1 to 2 As shown, the housing structure 100 includes a top shell 10 and an enclosure 20, both of which are connected to a bottom shell 201. The top shell 10 includes a top shell body 11 and a handle body 12. The enclosure 20 includes the enclosure body 21 and a handle appearance 22. The enclosure body 21 is connected to the top shell body 11, wrapping around the outer periphery of the top shell body 11 while leaving the handle body 12 free. The handle appearance 22 is detachably connected to the enclosure body 21 and, together with the handle body 12, forms a handle 30 for a user to grasp to move the energy storage device 200.

[0048] In the aforementioned housing structure 100, the handle 30 is formed by combining the handle body 12 and the handle appearance member 22. Firstly, the handle body 12 is fixedly connected to the top shell body 11, forming the main load-bearing structure of the housing structure. This provides the handle body 12 with improved structural strength, thereby serving as the primary load-bearing portion of the handle 30, ensuring its structural strength and reducing the risk of breakage. Secondly, the handle appearance member 22 is detachably connected to the housing body 21, making it easy to remove and replace. As part of the exterior design of the handle 30, the handle appearance member 22 allows the user to customize the color of the handle 30. Therefore, the housing structure 100, which combines the handle body 12 and the handle appearance member 22 to form the handle 30, not only improves the structural strength of the handle 30 but also enhances its assembly and disassembly efficiency. This not only facilitates replacement of the exterior design but also ensures the stability of the handle 30.

[0049] In some embodiments, the top shell body 11 and the handle body 12 are integrally formed, that is, the top shell 10 is an integrally formed part, which increases the connection strength between the handle body 12 and the top shell body 11, thereby further ensuring the structural strength of the handle body 12 and thus the structural strength of the handle 30. In other embodiments, the top shell body 11 and the handle body 12 can also be separate structures, and the handle body 12 can be detachably mounted to the top shell body 11, as long as the mounting strength is sufficient. At the same time, because the handle body 12 is replaceable, the user can also personalize the color of the handle body 12 to match the handle appearance 22, thereby enhancing the user experience.

[0050] In some embodiments, the housing structure 100 further includes a cover 40, which is connected to the top housing body 11 and the handle body 12.

The gripping space 15 connects the first gripping opening 13 and the second gripping opening 14, and is used to provide a gripping space for the user to grasp the handle 30. The cover 40 forms a boundary between the gripping space 15 and the accommodating cavity 203, thereby separating the gripping space 15 from the accommodating cavity 203, so that the accommodating cavity 203 is not exposed to the gripping space 15, thereby ensuring the sealing of the accommodating cavity 203.

[0051] Optionally, the cover shell 40, the top shell body 11, and the handle body 12 are integrally formed, that is, the cover shell 40 and the top shell 10 are integrally formed. Since the cover shell 40 is connected to the top shell body 11 and the handle body 12, the integrally formed cover shell 40 can improve the connection strength between the handle body 12 and the top shell body 11, thereby further ensuring the structural strength of the handle body 12 and the handle 30. In other embodiments, the cover shell 40 and the top shell 10 can also be split structures to facilitate the manufacture of the cover shell 40 and the top shell 10. For example, when the cover shell 40 and the top shell 10 are injection molded, the split structure can further simplify the molds of the cover shell 40 and the top shell 10, thereby improving the production efficiency of the cover shell 40 and the top shell 10.

[0052] In some embodiments, as Figures 1 to 3 As shown, the housing body 21 and the handle appearance member 22 enclose a mounting opening 23.

The central portion 112 protrudes toward the mounting opening 23 relative to the frame portion 111. The central portion 112 is disposed at the mounting opening 23 and is exposed at the mounting opening 23. The first gripping opening 13 is formed in the central portion 112 and communicates with the mounting opening 23, exposing the first gripping opening 13 so that the user can grip the handle 30.

[0053] Optionally, the outer contour of the central portion 112 is a rectangle with rounded corners, and the inner contour of the installation opening 23 is a rectangle of the same shape, so that after the top shell body 11 and the enclosure 20 are installed, the central portion 112 fits the installation opening 23 to ensure the sealing of the edge of the installation opening 23.

[0054] In some embodiments, as Figures 3 to 5As shown, the frame portion 111 is provided with a first through hole 1111, and the shell body 21 is provided with a first mounting portion 211 on the side facing the frame portion 111.

The second through hole 122 is aligned with the second mounting hole 2211. The handle body 12 and the handle appearance part 22 are fixedly connected with the second through hole 122 through a second locking part (not shown in the figure). The storage groove 121 receives the part of the second locking part located outside the second through hole 122 to avoid the second locking part protruding in the gripping space 15 and affecting the user's gripping feel.

[0057] Optionally, the second mounting portion 221 is a column and is protruding relative to the inner surface of the handle appearance 22. The inner wall of the second mounting hole 2211 has an internal thread. The second locking member is a screw.
