Technical Field

[0001] This utility model relates to the field of mobile energy storage device technology, specifically to a handcart, energy storage equipment, and mobile energy storage device. Background Technology

[0002] Currently, household energy storage power supplies are typically placed on the user's balcony. During use, there are situations where it is necessary to move the energy storage power supply from outdoors to indoors or vice versa. In addition, when users are working or playing outdoors, they usually carry energy storage power supplies because of the variety of electronic products they use, which consume power quickly, in order to avoid situations where electronic products run out of power and cannot be recharged.

[0003] However, energy storage power supplies in related technologies are generally large in size and weight, and require manual handling, which is time-consuming and laborious, causing many inconveniences to users and affecting their user experience. Utility Model Content

[0004] The embodiments of this utility model are intended to solve at least one of the technical problems existing in the prior art.

[0005] Therefore, a first aspect of the embodiments of this utility model provides a handcart.

[0006] A second aspect of the embodiments of this utility model provides an energy storage device.

[0007] A third aspect of the embodiments of this utility model provides a mobile energy storage device.

[0008] In view of the above, according to a first aspect of the present invention, a handcart is provided for an energy storage device. The handcart includes: a base with a placement surface for accommodating the energy storage device; a caster assembly disposed on the side of the base away from the placement surface; and a pull rod assembly movably connected to the base. The pull rod assembly is movable relative to the base between a first position and a second position. When the pull rod assembly is in the first position, it is used to connect to a pre-installed mounting structure of the energy storage device. When the pull rod assembly is separated from the mounting structure, it is movable from the first position to the second position.

[0009] The handcart provided in this embodiment of the utility model includes a base, a caster assembly, and a pull rod assembly. Specifically, the caster assembly is mounted on the base, and the pull rod assembly is movably connected to the base. Specifically, when it is necessary to change the placement of the energy storage device, such as moving it from an outdoor balcony to an indoor location, or when the user is carrying the energy storage device during outdoor activities, the energy storage device can be placed on the shelf of the base, and the pull rod assembly can be operated to easily move the energy storage device to the designated location, or the energy storage device can be easily dragged outdoors, improving the convenience of moving the energy storage device, making it more time-saving and labor-saving for users when moving the energy storage device, and helping to improve the user experience of the energy storage device.

[0010] Furthermore, when the tie rod assembly is in the first position, it can be connected to the pre-installed mounting structure of the energy storage device. Thus, when the tie rod assembly is operated to move the energy storage device, the base can provide reliable support for the energy storage device. At the same time, since the tie rod assembly is connected to both the base and the energy storage device, fixing the tie rod assembly, the base, and the energy storage device together can prevent the energy storage device from falling off the placement surface and being damaged during movement, which helps to improve the reliability of the energy storage device during movement.

[0011] In addition, the tie rod assembly can be separated from the reserved installation structure of the energy storage device, and the tie rod assembly can be moved to a second position to adjust the angle of the tie rod assembly relative to the energy storage device, which can improve the convenience and flexibility of operating the tie rod assembly to move the energy storage device.

[0012] In some technical solutions, optionally, based on the pull rod assembly being in the second position, the angle between the side of the pull rod assembly near the base and the placement surface is greater than 90°.

[0013] In this technical solution, when the pull rod assembly moves to the second position, the angle between the pull rod assembly and the placement surface is greater than 90°, i.e., an obtuse angle. This allows for easy control of the pull rod assembly to move the energy storage device, making it more time-saving and labor-saving for users when moving the energy storage device.

[0014] In some technical solutions, the trolley may optionally include a rotating assembly, and the pull rod assembly is rotatably connected to the base via the rotating assembly, and the pull rod assembly is rotatable relative to the base between a first position and a second position.

[0015] In this technical solution, when the pull rod assembly is separated from the reserved installation structure of the energy storage device, the pull rod assembly can be rotated from the first position to the second position. This not only saves time and effort when moving the energy storage device, but also further improves the convenience of operating the pull rod assembly, which is conducive to improving the user's experience of using the handcart.

[0016] In some technical solutions, the rotating assembly optionally includes a first rotating member and a second rotating member, wherein the first rotating member is connected to the base, the second rotating member is connected to the pull rod assembly, and the first rotating member and the second rotating member are rotatably connected.

[0017] In this technical solution, when the lever assembly is separated from the reserved installation structure of the energy storage device, the lever assembly can be rotated from the first position to the second position through the cooperation of the first rotating part and the second rotating part, which is conducive to further improving the flexibility and convenience of operating the lever assembly.

[0018] In some technical solutions, optionally, the first rotating member includes a first connecting part and a second connecting part, wherein the first connecting part is connected to the base, the second connecting part is connected to the first connecting part and rotatably connected to the second rotating member; the second connecting part is provided with a groove, and at least part of the second rotating member can be inserted into or removed from the groove.

[0019] In this technical solution, since the second connecting part is provided with a groove, and at least a part of the second rotating member can be inserted into or removed from the groove, on the one hand, the second rotating member can be limited to ensure the reliability of the rotation of the pull rod assembly between the first position and the second position. On the other hand, by providing the groove, the fasteners connecting the second rotating member and the pull rod assembly can be avoided to prevent interference, which is conducive to further improving the convenience of operating the pull rod assembly.

[0020] In some technical solutions, the tie rod assembly optionally includes a tie rod, a connecting plate, and a connecting component, wherein the connecting plate is disposed on the tie rod and connected to the second rotating member, and the connecting plate is detachably connected to the mounting structure through the connecting component.

[0021] In this technical solution, the connecting plate is detachably connected to the installation structure reserved for the energy storage device through the connecting assembly. In other words, the connection plate and the connecting assembly can realize the assembly between the tie rod and the energy storage device. This ensures a reliable fit between the tie rod assembly and the energy storage device, facilitates the movement of the energy storage device, and prevents the energy storage device from falling off the mounting surface. At the same time, the connection plate can be adjusted and replaced to accommodate tie rods of various forms and sizes, which helps to improve the flexibility and applicability of the assembly between the tie rod assembly and the energy storage device.

[0022] In some technical solutions, the connecting plate is optionally provided with a clearance groove, and the trolley also includes a fastener that connects the second rotating member and the connecting plate and is at least partially located within the clearance groove.

[0023] In this technical solution, since the connecting plate is provided with a clearance groove and at least some of the fasteners are located in the clearance groove, on the one hand, it can facilitate the assembly between the connecting plate and the second rotating part, and on the other hand, it can avoid the fasteners from interfering with other structures during the rotation of the pull rod assembly relative to the base, which is conducive to further improving the reliability of the trolley when moving the energy storage device.

[0024] In some technical solutions, optionally, the connecting component includes a first connecting component, which includes a first connector and a second connector. The first connector is used to connect the mounting structure, and the second connector is disposed on the connecting plate. The second connector can be connected or separated from the first connector.

[0025] In this technical solution, by setting a first connector and a second connector to connect or separate, the rapid installation and disassembly of the rod assembly and the energy storage device can be achieved.

[0026] In some technical solutions, optionally, the connecting plate includes a first connecting hole, the mounting structure includes a second connecting hole, and the connecting assembly includes a second connecting assembly that passes through the first connecting hole and is detachably connected to the second connecting hole.

[0027] This technical solution enables the assembly between the tie rod assembly and the energy storage device, which facilitates the movement of the energy storage device and improves the efficiency of assembly and disassembly between the tie rod assembly and the energy storage device.

[0028] In some technical solutions, the caster assembly optionally includes four casters, of which at least two casters have locking mechanisms, and the caster assembly cannot move when the locking mechanisms are locked.

[0029] In this technical solution, when the locking structure is locked, the caster assembly cannot move. This allows the trolley to stop moving and remain locked in its current position when the energy storage device is moved to a designated location, without the need to remove the energy storage device. This improves the convenience of using the energy storage device and enhances the user experience.

[0030] According to a second aspect of the present invention, an energy storage device is provided, including a mounting structure for detachably connecting to a pull rod assembly of a handcart. The handcart includes a base, a caster assembly, and a pull rod assembly. The base has a placement surface for accommodating the energy storage device. The caster assembly is located on the side of the base opposite to the placement surface. The pull rod assembly is movably connected to the base and is capable of moving relative to the base between a first position and a second position. The mounting structure connects to the pull rod assembly when it is in the first position. When the pull rod assembly is separated from the mounting structure, it can move from the first position to the second position, and the energy storage device is removably placed on the placement surface.

[0031] The energy storage device provided in this embodiment includes an installation structure. Specifically, the trolley includes a base, a caster assembly, and a pull rod assembly. The caster assembly is mounted on the base, and the pull rod assembly is movably connected to the base. Specifically, when it is necessary to change the placement of the energy storage device, such as moving it from an outdoor balcony to an indoor location, or when a user is carrying the energy storage device during outdoor activities, the energy storage device can be placed on the base's shelf, and the pull rod assembly can be operated to easily move the energy storage device to a designated location. Alternatively, the energy storage device can be easily dragged outdoors, improving the convenience of moving the energy storage device and making it more time-saving and labor-saving for users when moving the energy storage device, thus enhancing the user experience of the energy storage device.

[0032] Furthermore, when the tie rod assembly is in the first position, it can be connected to the pre-installed mounting structure of the energy storage device. Thus, when the tie rod assembly is operated to move the energy storage device, the base can provide reliable support for the energy storage device. At the same time, since the tie rod assembly is connected to both the base and the energy storage device, fixing the tie rod assembly, the base, and the energy storage device together can prevent the energy storage device from falling off the placement surface and being damaged during movement, which helps to improve the reliability of the energy storage device during movement.

[0033] In addition, the tie rod assembly can be separated from the reserved installation structure of the energy storage device, and the tie rod assembly can be moved to a second position to adjust the angle of the tie rod assembly relative to the energy storage device, which can improve the convenience and flexibility of operating the tie rod assembly to move the energy storage device.

[0034] According to a third aspect of this utility model, a mobile energy storage device is provided, comprising a trolley or energy storage device as provided in any of the above technical solutions, and thus possessing all the beneficial technical effects of the trolley or energy storage device, which will not be repeated here.

[0054] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0055] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0056] The following reference Figures 1 to 15 This invention describes a handcart 100, an energy storage device 200, and a mobile energy storage device provided according to some embodiments of the present invention.

[0057] In one embodiment according to this application, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, a handcart 100 is proposed for use with an energy storage device 200. The handcart 100 includes: a base 110 with a placement surface 111 for accommodating the energy storage device 200; a caster assembly 120 located on the side of the base 110 away from the placement surface 111; and a pull rod assembly 130 movably connected to the base 110. The pull rod assembly 130 is movable relative to the base 110 between a first position and a second position. When the pull rod assembly 130 is in the first position, it is connected to a pre-installed mounting structure 210 of the energy storage device 200. When the pull rod assembly 130 is separated from the mounting structure 210, it is movable from the first position to the second position.

[0058] The handcart 100 provided in this embodiment of the utility model includes a base 110, a caster assembly 120, and a pull rod assembly 130. Specifically, the caster assembly 120 is disposed on the base 110, and the pull rod assembly 130 is movably connected to the base 110. Specifically, when it is necessary to change the placement of the energy storage device 200, for example, moving it from an outdoor balcony to an indoor location, or when the user is carrying the energy storage device 200 during outdoor activities, the energy storage device 200 is placed on the placement surface 111 of the base 110, and the pull rod assembly 130 is operated to easily move the energy storage device 200 to the designated location, or the energy storage device 200 can be easily dragged outdoors, improving the convenience of moving the energy storage device 200, making it more time-saving and labor-saving for the user when moving the energy storage device 200, and improving the user's experience of using the energy storage device 200.

[0059] Furthermore, when the pull rod assembly 130 is in the first position, it can be connected to the reserved installation structure 210 of the energy storage device 200. Thus, when the pull rod assembly 130 is operated to move the energy storage device 200, the base 110 can provide reliable support for the energy storage device 200. At the same time, since the pull rod assembly 130 is connected to both the base 110 and the energy storage device 200, that is, the pull rod assembly 130, the base 110 and the energy storage device 200 are fixed together, it can be prevented that the energy storage device 200 will fall off the placement surface 111 and be damaged during the movement, which helps to improve the reliability of the energy storage device 200 during the movement.

[0060] Furthermore, the pull rod assembly 130 can be separated from the reserved mounting structure 210 of the energy storage device 200, and the pull rod assembly 130 can be moved to a second position to adjust the angle of the pull rod assembly 130 relative to the energy storage device 200, thereby improving the convenience and flexibility of operating the pull rod assembly 130 to move the energy storage device 200. It is understood that when the pull rod assembly 130 is separated from the reserved mounting structure 210 of the energy storage device 200, the energy storage device 200 can also be removed from the shelf 111.

[0061] In some embodiments, optionally, based on the second position of the pull rod assembly 130, the angle between the side of the pull rod assembly 130 near the base 110 and the placement surface 111 is greater than 90°.

[0062] In this embodiment, when the pull rod assembly 130 is separated from the reserved installation structure 210 of the energy storage device 200, the pull rod assembly 130 can be moved from the first position to the second position. When the pull rod assembly 130 moves to the second position, the angle between the pull rod assembly 130 and the placement surface 111 is greater than 90°, that is, an obtuse angle. This makes it easier to control the pull rod assembly 130 to move the energy storage device 200, making it more time-saving and labor-saving for the user when moving the energy storage device 200.

[0063] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the trolley 100 may optionally include a rotating assembly 140, and a pull rod assembly 130 is rotatably connected to the base 110 via the rotating assembly 140. The pull rod assembly 130 is rotatable relative to the base 110 between a first position and a second position.

[0064] In this embodiment, the trolley 100 is further defined as including a rotating component 140. Specifically, the pull rod assembly 130 is rotatably connected to the base 110 through the rotating component 140. That is, when the pull rod assembly 130 is separated from the reserved mounting structure 210 of the energy storage device 200, the pull rod assembly 130 can be rotated from the first position to the second position. This makes it more time-saving and labor-saving when moving the energy storage device 200, while further improving the convenience of operating the pull rod assembly 130, which is conducive to improving the user's experience of using the trolley 100.

[0065] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the rotating assembly 140 includes a first rotating member 141 and a second rotating member 142, wherein the first rotating member 141 is connected to the base 110, the second rotating member 142 is connected to the pull rod assembly 130, and the first rotating member 141 and the second rotating member 142 are rotatably connected.

[0066] In this embodiment, the rotating assembly 140 is defined to include a first rotating member 141 and a second rotating member 142. Specifically, the first rotating member 141 and the second rotating member 142 are rotatably connected. The first rotating member 141 is connected to the base 110, and the second rotating member 142 is connected to the pull rod assembly 130. That is, the pull rod assembly 130 is rotatably connected to the base 110 through the first rotating member 141 and the second rotating member 142.

[0067] Specifically, when the lever assembly 130 is separated from the installation structure 210 reserved in the energy storage device 200, the lever assembly 130 can be rotated from the first position to the second position through the cooperation of the first rotating member 141 and the second rotating member 142, which is conducive to further improving the flexibility and convenience of operating the lever assembly 130.

[0068] like Figure 4 and Figure 5As shown, in some embodiments, optionally, the first rotating member 141 includes a first connecting portion 143 and a second connecting portion 144, wherein the first connecting portion 143 is connected to the base 110, the second connecting portion 144 is connected to the first connecting portion 143 and is rotatably connected to the second rotating member 142; the second connecting portion 144 is provided with a groove 145, and at least a portion of the second rotating member 142 can be inserted into or removed from the groove 145.

[0069] In this embodiment, the first rotating member 141 is defined to include a first connecting part 143 and a second connecting part 144. Specifically, the first connecting part 143 is used to connect to the base 110. Optionally, the first connecting part 143 is provided with a threaded hole and is fixed to the base 110 by screws.

[0070] The second connecting part 144 is rotatably connected to the second rotating member 142, thereby realizing the rotational engagement between the pull rod assembly 130 and the base 110. Since the second connecting part 144 is provided with a groove 145, and at least a part of the second rotating member 142 can be inserted into or removed from the groove 145, on the one hand, the second rotating member 142 can be limited to ensure the reliability of the rotation of the pull rod assembly 130 between the first position and the second position. On the other hand, by providing the groove 145, the fastener 150 connecting the second rotating member 142 and the pull rod assembly 130 can be avoided to prevent interference, which is conducive to further improving the convenience of operating the pull rod assembly 130.

[0071] Optionally, the first connecting part 143 and the second connecting part 144 are an integral structure.

[0072] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 15 As shown, in some embodiments, optionally, the pull rod assembly 130 includes a pull rod 131, a connecting plate 132 and a connecting assembly 160, wherein the connecting plate 132 is disposed on the pull rod 131 and connected to the second rotating member 142, and the connecting plate 132 is detachably connected to the mounting structure 210 through the connecting assembly 160.

[0073] In this embodiment, the pull rod assembly 130 is defined to include a pull rod 131, a connecting plate 132, and a connecting component 160. Specifically, the connecting plate 132 is disposed on the pull rod 131 and is connected to the second rotating member 142.

[0074] Since the connecting plate 132 is detachably connected to the installation structure 210 reserved in the energy storage device 200 through the connecting assembly 160, the connection plate 132 and the connecting assembly 160 can realize the assembly between the tie rod 131 and the energy storage device 200. This ensures a reliable fit between the tie rod assembly 130 and the energy storage device 200, facilitates the movement of the energy storage device 200, and prevents the energy storage device 200 from falling off the mounting surface. At the same time, the connecting plate 132 can be adjusted and replaced to accommodate tie rods 131 of various forms and sizes, which helps to improve the flexibility and applicability of the assembly between the tie rod assembly 130 and the energy storage device 200.

[0075] Understandably, separating the connecting assembly 160 from the mounting structure 210 allows for the separation of the tie rod assembly 130 from the energy storage device 200. At this point, the tie rod assembly 130 can be moved to a second position to adjust its angle relative to the energy storage device 200.

[0076] Optionally, the connecting assembly 160 includes a Torx screw, a snap-fit ​​structure, or a plunger structure.

[0077] Optionally, there are multiple connecting components 160, with each mounting structure 210 corresponding to a connecting component 160. The multiple connecting components 160 are spaced apart, which can improve the stability and reliability of the assembly between the tie rod assembly 130 and the energy storage device 200.

[0078] Optionally, the tie rod assembly 130 includes a tie rod 131 and screws, wherein the tie rod 131 is directly connected to the mounting structure 210 reserved in the energy storage device 200 by screws, which is beneficial to reducing the cost of the energy storage device 200 compared to setting a connecting plate 132.

[0079] like Figure 3 As shown, in some embodiments, the connecting plate 132 is optionally provided with a clearance groove 133, and the handcart 100 also includes a fastener 150, which connects the second rotating member 142 and the connecting plate 132 and is at least partially located within the clearance groove 133.

[0080] In this embodiment, the trolley 100 is further defined as including a fastener 150, specifically, the fastener 150 is used to connect the second rotating member 142 and the connecting plate 132, thereby allowing the pull rod assembly 130 to rotate relative to the base 110 between a first position and a second position.

[0081] Since the connecting plate 132 is provided with a relief groove 133, and at least some of the fasteners 150 are located in the relief groove 133, on the one hand, it can facilitate the assembly between the connecting plate 132 and the second rotating member 142, and on the other hand, it can prevent the fasteners 150 from interfering with other structures during the rotation of the pull rod assembly 130 relative to the base 110, which is conducive to further improving the reliability of the trolley 100 when realizing the movement of the energy storage device 200.

[0082] Optionally, fastener 150 includes screws, bolts, or clips.

[0083] like Figure 7 , Figure 11 , Figure 13 and Figure 14 As shown, in some embodiments, optionally, the connecting component 160 includes a first connecting component 161, the first connecting component 161 includes a first connector 211 and a second connector 162, wherein the first connector 211 is used to connect the mounting structure 210, the second connector 162 is disposed on the connecting plate 132, and the second connector 162 can cooperate with the first connector 211 to connect or separate.

[0084] In this embodiment, the installation structure 210 is defined to include a first connector 211, that is, the installation structure 210 reserved by the energy storage device 200 is the first connector 211. Optionally, the first connector 211 includes a connecting body and a mounting hole. The mounting hole is provided on the energy storage device 200, and the connecting body is connected to the mounting hole by screws.

[0085] The second connector 162 is disposed on the connecting plate 132, and the second connector 162 can be connected or separated from the first connector 211. Specifically, when it is necessary to move the energy storage device 200, the energy storage device 200 is placed on the placement surface 111, and the first connector 211 and the second connector 162 are connected to fix the pull rod assembly 130 on the energy storage device 200. By operating the pull rod assembly 130, the energy storage device 200 can be easily moved to the designated position by the caster assembly 120, which can also improve the reliability of the energy storage device 200 during the movement process.

[0086] In addition, during the process of moving the energy storage device 200, the second connector 162 can be separated from the first connector 211, and the pull rod assembly 130 can be moved to the second position to adjust the angle of the pull rod assembly 130 relative to the energy storage device 200, which can improve the convenience and flexibility of operating the pull rod assembly 130 to move the energy storage device 200.

[0087] By setting the first connector 211 and the second connector 162 to connect or separate, the rod assembly 130 and the energy storage device 200 can be quickly installed and disassembled.

[0099] In this embodiment, the caster assembly 120 includes four casters 121, optionally arranged at intervals on the base 110. Since at least the casters 121 have a locking structure 170, and the caster assembly 120 cannot move when the locking structure 170 is locked, when the energy storage device 200 moves to a designated position, the locking structure 170 can be used to lock the entire trolley 100, stopping its movement and locking it in the current position without needing to remove the energy storage device 200. This improves the convenience of using the energy storage device 200 and enhances the user experience.

[0100] According to a second aspect of the present invention, an energy storage device 200 is provided, including a mounting structure 210 for detachably connecting to a pull rod assembly 130 of a trolley 100. The trolley 100 includes a base 110, a caster assembly 120, and a pull rod assembly 130. The base 110 has a placement surface 111 for accommodating the energy storage device 200. The caster assembly 120 is located on the side of the base 110 opposite to the placement surface 111. The pull rod assembly 130 is movably connected to the base 110 and can move relative to the base 110 between a first position and a second position. When the pull rod assembly 130 is in the first position, the mounting structure 210 connects to the pull rod assembly 130. When the pull rod assembly 130 is separated from the mounting structure 210, the pull rod assembly 130 can move from the first position to the second position. The energy storage device 200 is removably placed on the placement surface 111.

[0101] The energy storage device 200 provided in this embodiment of the utility model includes an installation structure 210.

[0102] Furthermore, when the pull rod assembly 130 is in the first position, it can be connected to the reserved installation structure 210 of the energy storage device 200. Thus, when the pull rod assembly 130 is operated to move the energy storage device 200, the base 110 can provide reliable support for the energy storage device 200. At the same time, since the pull rod assembly 130 is connected to both the base 110 and the energy storage device 200, that is, the pull rod assembly 130, the base 110 and the energy storage device 200 are fixed together, it can be prevented that the energy storage device 200 will fall off the placement surface 111 and be damaged during the movement, which helps to improve the reliability of the energy storage device 200 during the movement.

[0103] Furthermore, the pull rod assembly 130 can be separated from the reserved mounting structure 210 of the energy storage device 200, and the pull rod assembly 130 can be moved to a second position to adjust the angle of the pull rod assembly 130 relative to the energy storage device 200, thereby improving the convenience and flexibility of operating the pull rod assembly 130 to move the energy storage device 200. It is understood that when the pull rod assembly 130 is separated from the reserved mounting structure 210 of the energy storage device 200, the energy storage device 200 can also be removed from the shelf 111.

[0104] like Figure 6 and Figure 7 As shown, the energy storage device 200 further includes a mounting structure 210 for adapting to the pull rod assembly 130. Since the pull rod assembly 130 is separate from the mounting structure 210, the energy storage device 200 is removably mounted on the placement surface 111.

[0105] Specifically, when it is necessary to change the placement of the energy storage device 200, such as moving it from an outdoor balcony to an indoor location, or when the user is carrying the energy storage device 200 during outdoor activities, the energy storage device 200 can be placed on the shelf 111 of the base 110 and the pull rod assembly 130 can be operated to easily move the energy storage device 200 to the designated location, or the energy storage device 200 can be easily dragged outdoors, improving the convenience of moving the energy storage device 200, making it more time-saving and labor-saving for users when moving the energy storage device 200, and helping to improve the user experience of the energy storage device 200.

[0106] Furthermore, when the pull rod assembly 130 is in the first position, it can be connected to the reserved installation structure 210 of the energy storage device 200. Thus, when the pull rod assembly 130 is operated to move the energy storage device 200, the base 110 can provide reliable support for the energy storage device 200. At the same time, since the pull rod assembly 130 is connected to both the base 110 and the energy storage device 200, that is, the pull rod assembly 130, the base 110 and the energy storage device 200 are fixed together, it can be prevented that the energy storage device 200 will fall off the placement surface 111 and be damaged during the movement, which helps to improve the reliability of the energy storage device 200 during the movement.

[0107] Furthermore, the pull rod assembly 130 can be separated from the reserved mounting structure 210 of the energy storage device 200, and the pull rod assembly 130 can be moved to a second position to adjust the angle of the pull rod assembly 130 relative to the energy storage device 200, thereby improving the convenience and flexibility of operating the pull rod assembly 130 to move the energy storage device 200. It is understood that when the pull rod assembly 130 is separated from the reserved mounting structure 210 of the energy storage device 200, the energy storage device 200 can also be removed from the shelf 111.
