[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. 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. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0045] The energy storage power supply is usually provided with a handle, which is usually arranged on the upper cover of the energy storage power supply. The upper cover of the energy storage power supply has a design of combining a decorative cover plate and a main shell.

[0046] In the related art, when the handle is formed, it is usually necessary to assemble a part of the decorative cover and a part of the main shell to form the upper part of the handle, and then use an independent part as the lower part of the handle to assemble a complete handle. However, the assembly is time-consuming and labor-intensive, and the cost of parts is relatively high.

[0047] In view of this, the present application provides a shell structure and energy storage device that can improve assembly efficiency and reduce costs. The shell structure includes a panel and a frame. The panel includes a main board and a first grip portion, the first grip portion is integrally formed with the main board and is bent toward the bottom of the main board. The frame includes a main frame and a second grip portion, the second grip portion is integrally formed with the main frame, and the first grip portion is configured to be below the second grip portion through the area enclosed by the main frame during the assembly process of the main board and the main frame, and is assembled with the second grip portion to form a handle.

[0048] In the shell structure provided by the present application, the first gripping part is integrally formed on the panel, and the second gripping part is integrally formed on the frame, so that after the panel and the frame are assembled, the first gripping part and the second gripping part are combined to form a handle. Compared with the method of forming a handle by a decorative cover plate, a main shell and an independent part in the related art, in the shell structure of the present application, the first gripping part is integrally formed on the panel, thereby eliminating independent parts, and the first gripping part is used as the lower half of the handle and the second gripping part is used as the upper half of the handle, so that the panel and the frame are combined to form a handle, thereby improving the assembly efficiency of the handle and reducing the manufacturing cost of the handle.

[0049] The following is combined with Figures 1 to 10 , 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.

[0050] like Figures 1 to 2As shown in the figure, in some embodiments of the present application, a housing structure 100 and an energy storage device 200 are provided. The energy storage device 200 includes a bottom case 201 and the housing structure 100. The housing structure 100 is connected to the bottom case 201 as the upper case of the energy storage device 200, and a receiving cavity 202 is formed between the housing structure 100 and the bottom case 201. The receiving cavity 202 is used to receive the battery cell assembly 203 and the circuit board 204 in the energy storage device 200 and so on.

[0051] As an exemplary example, the energy storage device 200 can be a portable power source applied to outdoor scenarios, or a home energy storage system for home energy storage, etc. The circuit board 204 is used as an inverter module to control the charging and discharging of the battery cell assembly 203, so as to realize the power supply of the battery cell assembly 203 to external devices, or realize the charging of the battery cell assembly 203 by external devices.

[0052] As Figures 2 to 4 shown in the figure, in some embodiments, the housing structure 100 includes a panel 10 and a frame 20. The panel 10 includes a main board body 11 and a first holding portion 12. The first holding portion 12 is integrally formed on the main board body 11, and the first holding portion 12 bends downward toward the main board body 11. The frame 20 includes a main frame portion 21 and a second holding portion 22. The second holding portion 22 is integrally formed on the main frame portion 21. When the panel 10 and the frame 20 are installed, the first holding portion 12 moves to the lower part of the second holding portion 22 through the area surrounded by the main frame portion 21, and the first holding portion 12 and the second holding portion 22 are combined to form a handle 30. The handle 30 is provided for the user to hold to move the energy storage device 200.

[0053] The housing structure 100 is integrally formed on the panel 10 through the first holding portion 12, and then integrally formed on the frame 20 through the second holding portion 22. After the panel 10 and the frame 20 are assembled, the first holding portion 12 and the second holding portion 22 are combined to form the handle 30. Compared with the way of forming a handle by a decorative cover plate, a main housing and independent parts in the related art, in the housing structure 100 of the present application, since the first holding portion 12 is integrally formed on the panel 10, independent parts are omitted. By using the first holding portion 12 as the lower half of the handle 30 and the second holding portion 22 as the upper half of the handle 30, the panel 10 and the frame 20 are combined to form the handle 30. Therefore, the assembly efficiency of the handle 30 is improved and the manufacturing cost of the handle 30 is reduced.

[0054] In addition, the housing structure 100 is integrally formed with the panel 10 through the first holding part 12, and integrally formed with the frame 20 through the second holding part 22. The first holding part 12 serves as the lower half of the handle 30, and the second holding part 22 serves as the upper half of the handle 30, making it easier for the handle 30 to form a color-blocking combination. As long as the panel 10 and the frame 20 are set to different colors, the color-blocking combination of the upper and lower parts of the handle 30 can be achieved, which is beneficial to improving the visual aesthetic feeling.

[0055] In some embodiments, the energy storage device 200 further includes a control board 205. The control board 205 is disposed on the same side of the panel 10 and the bottom case 201. The control board 205 has buttons or sockets, etc., for the user to operate and use the energy storage device 200.

[0056] As Figure 4 and Figure 5 shown, in some embodiments, a first avoidance opening 13 is formed between the main board body 11 and the first holding part 12, and an installation opening 23 is formed by enclosing the top of the main frame part 21 and the second holding part 22. When the panel 10 and the frame 20 are installed, the main board body 11 is installed in the installation opening 23, the first avoidance opening 13 communicates with the installation opening 23, and the first holding part 12 is moved to the lower side of the second holding part 22 through the installation opening 23. The main frame part 21 forms a second avoidance opening 24 communicating with the installation opening 23 on one side of the second holding part 22. When the panel 10 and the frame 20 are assembled, the second avoidance opening 24 communicates with the first avoidance opening 13 to form a holding space 40. The holding space 40 is used to provide a hand-holding space for the user to hold the handle 30.

[0057] As Figure 2 、 Figure 4 and Figure 5 shown, in some embodiments, after the panel 10 and the frame 20 are assembled, since the installation opening 23 communicates with the accommodation cavity 202, the holding space 40 formed by the second avoidance opening 24 and the first avoidance opening 13 will also communicate with the accommodation cavity 202. However, the holding space 40 communicating with the outside will expose the accommodation cavity 202. Therefore, in order to separate the holding space 40 and the accommodation cavity 202, the housing structure 100 further includes a cover body 50. The cover body 50 is connected to the main board body 11, the first holding part 12 and the main frame part 21. The cover body 50 forms a boundary between the holding space 40 and the accommodation cavity 202, thereby separating the holding space 40 and the accommodation cavity 202, so that the accommodation cavity 202 will not be exposed to the holding space 40 to ensure the sealing of the holding space 40.

[0058] In some embodiments, the outer contour of the panel 10 is rectangular, the first holding portion 12 is formed at the edge of one side of the panel 10, the frame body 20 is in the shape of a rectangular frame, the contour of the mounting opening 23 is rectangular, and the outer contour of the panel 10 is the same as the contour of the mounting opening 23. After the panel 10 is installed on the frame body 20, the panel 10 fits into the mounting opening 23 to ensure the sealing performance of the edge of the mounting opening 23.

[0059] As Figures 6 to 8 shown, in some embodiments, a first abutting rib 121 is provided on the side of the first holding portion 12 facing the second holding portion 22, and a second abutting rib 221 is provided on the side of the second holding portion 22 facing the first holding portion 12. The first abutting rib 121 abuts against the second abutting rib 221 to position the first holding portion 12 and the second holding portion 22, and prevent the relative displacement of the first holding portion 12 and the second holding portion 22 from affecting the user's hand feeling.

[0060] In some embodiments, the first abutting rib 121 has a first stop surface 1211 and a limiting portion 1212 protruding relative to the first stop surface 1211, and the second abutting rib 221 has a second stop surface 2211. The second stop surface 2211 abuts against the first stop surface 1211 to prevent the first holding portion 12 and the second holding portion 22 from moving closer. The limiting portion 1212 abuts against the side of the second abutting rib 221 parallel to the first stop surface 1211 to limit the second abutting rib 221 in the direction parallel to the first stop surface 1211, thereby preventing the misalignment movement of the first holding portion 12 and the second holding portion 22.

[0061] In some embodiments, a limiting protrusion 122 is further provided on the side of the first holding portion 12 facing the second holding portion 22, and a limiting piece 222 is further provided on the side of the second holding portion 22 facing the first holding portion 12. The limiting protrusion 122 is formed with a convex angle 1221, the limiting piece 222 is formed with a groove 2221, the convex angle 1221 is located in the groove 2221, and the edge of the convex angle 1221 abuts against the groove wall of the groove 2221 to limit the relative displacement of the first holding portion 12 and the second holding portion 22.

[0062] In some embodiments, the first holding portion 12 has a plurality of first abutting ribs 121, and a first reinforcing rib 123 is provided between two adjacent first abutting ribs 121 of the first holding portion 12.

[0063] In some embodiments, the second holding portion 22 has a plurality of parallel limiting pieces 222, and a second reinforcing rib 223 is provided between two adjacent limiting pieces 222 of the second holding portion 22. The second reinforcing rib 223 connects two adjacent limiting pieces 222 to improve the strength of the limiting pieces 222.

[0064] In some embodiments, a socket 224 is provided at the bottom of the second holding part 22. The cross-sectional shape of the first holding part 12, excluding the first abutting rib 121, the limiting bump 122, and the first reinforcing rib 123, is C-shaped. The top end of the first holding part 12 abuts against the top surface of the second abutting rib 221, and the bottom end of the first holding part 12 is inserted into the socket 224, thereby restricting the relative displacement between the first holding part 12 and the second holding part 22.

[0065] As Figure 5 , Figures 8 to 10 shown, in some embodiments, an installation groove 124 is provided on the side of the first holding part 12 facing away from the second holding part 22. A first installation hole 1241 is provided on the groove bottom surface of the installation groove 124 of the first holding part 12. A second installation hole 225 is provided on the side of the second holding part 22 facing the first holding part 12. After the first holding part 12 and the second holding part 22 are spliced, the first installation hole 1241 is aligned with the second installation hole 225. The housing structure 100 further includes a first locking member (not shown in the figure). The first locking member extends into the aligned first installation hole 1241 and the second installation hole 225 to fix the first holding part 12 and the second holding part 22. The installation groove 124 accommodates the part of the first locking member outside the first installation hole 1241, preventing the first locking member from protruding into the holding space 40 and affecting the user's holding feel. As an exemplary example, the first locking member is a screw.

[0066] In some embodiments, the main board body 11 is provided with a buckle 111, and the main frame part 21 is provided with a slot 211. The buckle 111 and the slot 211 are in snap-fit to fix the main board body 11 and the main frame part 21, thereby realizing the assembly of the panel 10 and the frame body 20.

[0067] Optionally, the main board body 11 is provided with a plurality of buckles 111, and the main frame part 21 is provided with a plurality of slots 211.
