In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0033] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0034] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts.

For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0036] Figure 1 The schematic diagram of the structure of the energy storage device provided by the present application is shown. Figure 1 As shown, the energy storage device includes a shell, a battery cell module, an interface and a control panel. The shell is not only used to accommodate and install the battery cell module, but also to install the interface and the control panel; the interface includes a charging interface and a discharging interface; the control panel is communicatively connected with the control system of the energy storage device to facilitate the user to adjust the working mode of the energy storage device according to needs; the battery cell module is used for storing and releasing electric energy to meet the user's energy storage and electricity needs.

[0037] The energy storage device can be used on a household balcony. The energy storage device is charged through photoelectric conversion by a photovoltaic panel installed on the balcony or city electricity, and then the energy storage device is used to power household electrical appliances.

[0038] Unlike traditional large-scale household energy storage devices, balcony photovoltaic energy storage devices are relatively small and easy to carry and move. They can also be moved according to the user's power demand, such as from the balcony to the garage or even outdoors. In the prior art, most balcony photovoltaic energy storage devices have no handles, or only have hand grip grooves on the outer shell of the energy storage device. The design without handles or hand grip grooves is not convenient for users to move the energy storage device, which increases the difficulty of users to move and use, and the user experience is not good.

[0039] In order to facilitate the transfer of the energy storage device, the housing includes a main housing 100 and a handle 200. The main housing 100 includes a top cover 101 and a plurality of side wall panels 102 arranged around the top cover 101. At least two of the plurality of side wall panels 102 arranged opposite to each other are provided with handles 200. The handles 200 are designed so that the user can lift and transfer the energy storage device by hand using the handles 200. During the transfer of the energy storage device, two operators are required to lift the two handles 200 arranged opposite to each other, and then lift and transfer the energy storage device.

[0040] Next, for ease of understanding, the up and down in the height direction of the shell is defined as "up and down" or "high and low", the length direction of the side wall plate 102 with the handle 200 is defined as the "length direction of the shell", and the direction perpendicular to the length direction and height direction of the shell is defined as the "width direction of the shell".

[0041] Figure 2 A cross-sectional schematic diagram showing the handle 200 provided in the present application in a hand-carrying position is shown. Figure 3 FIG. 2 shows a cross-sectional schematic diagram of the handle 200 provided by the present application in the storage position. Figures 2 to 3 Combined with Figure 1 As shown, the upper ends of the two oppositely arranged side wall panels 102 are each provided with a card slot 103 with an opening facing downward, and the handle 200 includes a card connection portion 201 and a hand-held portion 202 connected to the card connection portion 201 and extending in the horizontal direction. The hand-held portion 202 is configured to be held by a user, and the card connection portion 201 can be inserted into the card slot 103 and rotated around a horizontal axis in the card slot 103, so that the hand-held portion 202 has a hand-held position away from the side wall panel 102 and higher than the card slot 103, and a storage position close to the side wall panel 102 and lower than the card slot 103. When it is necessary to lift and transfer the energy storage device, the handle 200 can be rotated relative to the side wall panel 102 to a state of being tilted upward relative to the side wall panel 102. At this time, the hand-held portion 202 is in a hand-held position away from the side wall panel 102 and higher than the card slot 103 (such as Figure 2 When the energy storage device does not need to be lifted, the handle 200 can be rotated relative to the side wall plate 102 to a state substantially parallel to the side wall plate 102. At this time, the hand-held portion 202 is in a storage position close to the side wall plate 102 and lower than the card slot 103 (such as Figure 3 state) to reduce the space occupied by the handle 200, and is suitable for use in a small space.

[0042] In addition, the handle 200 provided in the present application can be rotated to a desired position as needed. When the handle 200 is in the hand-carrying position, it is convenient for the user's palm to fully grasp it. After the handle 200 is subjected to force, the handle 200 is stabilized in the hand-carrying position, and a certain space is reserved for the user's palm to tighten, thereby improving the comfort of grip. Compared with the existing hand-grip groove that can only be grasped with the finger joints, the handle 200 has a good grip feel and is convenient for the user to exert force.

[0043] In order to better store the handle 200, the outer surface of the side wall plate 102 has a recessed portion 104, the slot 103 is located in the recessed portion 104, and the handle 200 can be accommodated in the recessed portion 104. When the handle 200 is in the storage position, the handle 200 can be accommodated in the recessed portion 104.

[0044] The handle 200 further includes a connecting portion 203, the clamping portion 201 and the hand-held portion 202 are arranged in parallel and spaced apart, and the connecting portion 203 is used to connect the clamping portion 201 and the hand-held portion 202. Further, the two connecting portions 203 are respectively connected to the two ends of the clamping portion 201 and connected to the hand-held portion 202, and the handle 200 is in a rectangular ring shape as a whole.

[0045] In this embodiment, the shape of the recessed portion 104 is roughly rectangular, and the two side walls of the recessed portion 104 in the height direction of the shell are recorded as the upper side wall and the lower side wall, and the two side walls of the recessed portion 104 in the length direction of the shell are recorded as the left side wall and the right side wall, and the card slot 103 is located at the upper side wall of the recessed portion 104. The left side wall, the right side wall and the lower side wall of the recessed portion 104 are all arranged at an obtuse angle with the bottom wall of the recessed portion 104, that is, the opening of the recessed portion 104 is expanded to facilitate the assembly of the handle 200 and the card slot 103.

[0046] The depth of the recessed portion 104 is greater than the thickness of the handle 200 in the width direction of the housing, so that the handle 200 is completely accommodated in the recessed portion 104 when in the storage position.

[0047] In order to facilitate the rotation of the clamping portion 201 of the handle 200 relative to the clamping slot 103, the clamping portion 201 of the handle 200 is cylindrical, extends along the length direction and is rotatably disposed in the clamping slot 103. Further, in order to reduce the friction between the clamping portion 201 and the clamping slot 103, the longitudinal section of the clamping portion 201 is an inverted U shape, and the clamping slot 103 has an arc surface that matches the circumferential surface of the clamping portion 201.

[0048] In one embodiment, the clamping portion 201 is made of a metal material with high structural strength to prevent the clamping portion 201 from being deformed by force. At the same time, the appearance of the metal material is easy to be processed into a smooth surface, which can further reduce the friction between the clamping portion 201 and the clamping slot 103. In one embodiment, the clamping portion 201, the connecting portion 203 and the hand-held portion 202 of the handle 200 are an integrated structure, and the integrated molding does not require assembly, which can improve the assembly efficiency of the entire shell.

[0049] In one embodiment, the main housing 100 further includes a snap-fit ​​structure 300, the snap-fit ​​structure 300 includes a fixing portion 301 and an elastic arm 302 fixedly connected to the fixing portion 301, the fixing portion 301 is fixed to the side wall plate 102, the elastic arm 302 extends downward and forms a slot 103 with the outer surface of the side wall plate 102. At this time, the snap-fit ​​structure 300 can be detachably fixed to the side wall plate 102, or it can be integrally formed with the side wall plate 102. In another embodiment, the fixing portion 301 of the snap-fit ​​structure 300 is fixed to the side wall plate 102, and its elastic arm 302 extends downward and forms a slot 103 with the fixing portion 301. At this time, the snap-fit ​​structure 300 can be detachably fixed to the side wall plate 102, or it can be integrally formed with the side wall plate 102. It can be understood that as long as the slot 103 with the opening facing downward can be formed on the side wall plate 102, the molding method of the slot 103 is not limited here.

[0050] Figure 4 FIG. 1 shows a cross-sectional schematic diagram of the card slot 103 provided in the present application. Figure 4 As shown, the lower end of the side surface of the elastic arm 302 located in the slot 103 has a protrusion 303 to restrict the clamping portion 201 in the slot 103 and prevent the clamping portion 201 from being separated from the slot 103. The protrusion 303 has a guide surface 3031 extending from bottom to top in a direction close to the side wall plate 102, and the lower end of the guide surface 3031 is connected to the elastic arm 302. Through the provision of the guide surface 3031, it is convenient to install the clamping portion 201 in the slot 103. The protrusion 303 has a stop surface 3032 extending from bottom to top in a direction away from the side wall plate 102, and the lower end of the stop surface 3032 is connected to the upper end of the guide surface 3031. Through the provision of the stop surface 3032, it is possible to further prevent the clamping portion 201 from being separated from the slot 103.

[0051] The clamping part 201 is cylindrical. When the clamping part 201 is inserted into the slot 103, the circumferential surface of the clamping part 201 abuts against the guide surface 3031. When the clamping part 201 moves upward, the elastic arm 302 can be deformed outward, so that the clamping part 201 can be smoothly inserted into the slot 103. When the clamping part 201 enters the slot 103, the clamping part 201 no longer exerts force on the guide surface 3031, the elastic arm 302 returns to its original state, and the stop surface 3032 abuts against the clamping part 201 to limit the clamping part 201 in the slot 103. Furthermore, the stop surface 3032 is an arc surface, which not only facilitates the rotation of the clamping part 201 in the slot 103, but also enables the stop surface 3032 to better contact with the circumferential surface of the clamping part 201, thereby preventing the clamping part 201 from being separated from the slot 103.

[0052] In one embodiment, at least two protrusions 303 are arranged at intervals along the length direction. For example, the number of protrusions 303 can be any number such as two, three, four, five, six, seven, eight, etc., and can be specifically designed according to the size of the protrusions 303 and the elastic arms 302 in the length direction of the side wall plate 102, and is not limited here.

[0053] The energy storage device provided in the present application is designed with a detachable and rotatable handle 200 on the outer shell, which is not only convenient for installation, but also the handle 200 can be rotated as needed to facilitate carrying or storing the energy storage device, thereby improving the user experience.

[0054] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the above embodiments do not limit the present application in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
