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 retrofit mobile vehicle.

[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 system.

[0008] In view of the above, according to a first aspect of the present invention, a rear-mounted mobile vehicle is provided for an energy storage device. The rear-mounted mobile vehicle includes: a rear-mounted support base, the rear-mounted support base having a support surface for accommodating the energy storage device; rear-mounted mobile wheels, located on the side of the rear-mounted support base away from the support surface; and a rear-mounted tie rod assembly, located on the rear-mounted support base, the rear-mounted tie rod assembly being detachably connected to a pre-reserved connection structure of the energy storage device.

[0009] The rear-mounted mobile vehicle provided in this embodiment includes a rear-mounted support base, rear-mounted moving wheels, and a rear-mounted pull rod assembly. 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 is placed on the support surface of the rear-mounted support base, and the rear-mounted pull rod assembly is connected to the pre-reserved connection structure of the energy storage device. By operating the rear-mounted pull rod assembly, the energy storage device can be easily moved to a designated location, or the energy storage device can be easily towed outdoors, improving the convenience of moving the energy storage device and making it more time-saving and labor-saving for users when using the energy storage device, thus enhancing the user experience of the energy storage device.

[0010] In addition, when the rear-mounted tie rod assembly is used to move the energy storage device, the rear-mounted support can provide reliable support for the energy storage device. Moreover, since the rear-mounted tie rod assembly is connected to both the rear-mounted support and the energy storage device, thus fixing the three together, it can prevent the energy storage device from falling off the support surface and being damaged during movement, which helps to improve the reliability of the energy storage device during movement.

[0011] In addition, in special scenarios, there may be some water accumulation on the balcony, or there may be rainwater outdoors. When the energy storage device is placed on a support surface, that is, a support base is set at the bottom of the energy storage device, it can play a certain waterproof role and help improve the overall reliability of the energy storage device.

[0012] Understandably, separating the rear-mounted tie rod assembly from the pre-installed connection structure of the energy storage device allows the energy storage device to be removed from the support surface.

[0013] In some technical solutions, the rear-mounted caster wheel can be optionally detachably connected to the rear-mounted support.

[0014] In this technical solution, since the energy storage device is placed on the support surface of the rear-mounted support base, that is, the rear-mounted support base is formed as a support structure for supporting the energy storage device, so that the energy storage device is supported to a certain height. In the case of water accumulation in places such as balconies, it can play a certain waterproof role, which is conducive to improving the reliability of the energy storage device and extending the service life of the energy storage device.

[0015] In some technical solutions, optionally, a hollow cavity is provided on the side of the rear-mounted support seat away from the support surface.

[0016] In this technical solution, while ensuring reliable support for the energy storage device, the overall weight of the rear support base can be reduced, thus achieving lightweighting of the rear mobile vehicle and helping to reduce the production cost of the rear mobile vehicle.

[0018] In this technical solution, since the first and second plates are rotatably connected and the rear-mounted moving wheel is mounted on the second plate, when the rear-mounted tie rod assembly is operated to drive the energy storage device to move, the rear-mounted tie rod assembly can drive the energy storage device to rotate relative to the second plate, which is beneficial to improving the flexibility and convenience of operating the rear-mounted tie rod assembly.

[0019] In some technical solutions, optionally, the rear-mounted tie rod assembly includes a tie rod rear-mount component, a connecting plate, and a rear-mounted connecting assembly, wherein the connecting plate is disposed on the tie rod rear-mount component, at least one of the connecting plate and the tie rod rear-mount component is connected to the rear-mounted support base, and the connecting plate is detachably connected to the connecting structure through the rear-mounted connecting assembly.

[0020] In this technical solution, the connecting plate is detachably connected to the pre-reserved connection structure of the energy storage device through the post-installed connecting assembly. In other words, the assembly between the tie rod and the energy storage device can be achieved through the connecting plate and the post-installed connecting assembly. This ensures a reliable fit between the post-installed 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 support surface. At the same time, the connecting 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 post-installed tie rod assembly and the energy storage device.

[0021] In some technical solutions, optionally, the retrofit connection assembly includes a first retrofit connection assembly, which includes a first connector and a second connector. The first connector is used to connect the connection structure, and the second connector is disposed on the connection plate. The second connector can be connected or separated from the first connector.

[0022] In this technical solution, when the energy storage device needs to be moved, the energy storage device is placed on the support surface, and the first connector and the second connector are connected to fix the rear-mounted tie rod assembly on the energy storage device. By operating the rear-mounted tie rod assembly, the energy storage device can be easily moved to the designated position by the rear-mounted moving wheels, which can also improve the reliability of the energy storage device during the movement process.

[0023] Understandably, when the energy storage device is moved to a designated location, separating the first and second connectors allows the energy storage device to be removed from the support surface. By setting the first and second connectors to connect or separate, rapid installation and disassembly between the retrofitted tie rod assembly and the energy storage device can be achieved, facilitating the movement of the energy storage device while improving the efficiency of assembly and disassembly between the retrofitted tie rod assembly and the energy storage device.

[0024] In some technical solutions, optionally, the first connector includes a first buckle, and the second connector includes a base and a second buckle, wherein the base is disposed on the connecting plate, and the second buckle is movably disposed on the base, and the second buckle is used to engage or disengage with the first buckle.

[0025] In this technical solution, by connecting or separating the first and second clips, the rapid installation and disassembly of the rear-mounted tie rod assembly and the energy storage device can be achieved. This facilitates the movement of the energy storage device and improves the efficiency of the installation and disassembly between the rear-mounted tie rod assembly and the energy storage device.

[0026] In some technical solutions, optionally, the first connecting member includes a limiting hole, and the second connecting member includes a mounting part and a limiting pin. The mounting part is disposed on the connecting plate, and the limiting pin is movably disposed on the mounting part. The limiting pin is used to insert into or remove from the limiting hole.

[0027] In this technical solution, by inserting or removing the limiting pin from the limiting hole, the quick installation and disassembly of the retrofitted tie rod assembly and the energy storage device can be achieved. This facilitates the movement of the energy storage device and improves the efficiency of the installation and disassembly between the retrofitted tie rod assembly and the energy storage device.

[0028] In some technical solutions, optionally, the connecting plate is provided with a first connecting hole, and the connecting structure includes a second connecting hole; the rear-mounted connecting assembly includes a second rear-mounted connecting assembly, which passes through the first connecting hole and is detachably connected to the second connecting hole.

[0029] In this technical solution, the connecting plate is provided with a first connecting hole, and the second rear-mounted connecting component passes through the first connecting hole and is detachably connected to the second connecting hole, thereby realizing the assembly between the rear-mounted tie rod assembly and the energy storage device. While facilitating the movement of the energy storage device, it can also improve the assembly and disassembly efficiency between the rear-mounted tie rod assembly and the energy storage device.

[0030] According to a second aspect of the present invention, an energy storage device is provided, including a connecting structure for detachably connecting to a rear-mounted tie rod assembly of a rear-mounted mobile vehicle. The rear-mounted mobile vehicle includes a rear-mounted support base, rear-mounted mobile wheels, and a rear-mounted tie rod assembly. The rear-mounted support base has a supporting surface. Based on the separation of the connecting structure from the rear-mounted tie rod assembly, the energy storage device can be placed on the supporting surface in a detachable manner. The rear-mounted mobile wheels are located on the side of the rear-mounted support base away from the supporting surface.

[0031] The energy storage device provided in this embodiment includes a connecting structure. Specifically, the rear-mounted mobile vehicle includes a rear-mounted support base, rear-mounted moving wheels, and a rear-mounted pull rod assembly. 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 is placed on the support surface of the rear-mounted support base, and the rear-mounted pull rod assembly is connected to the pre-reserved connecting structure of the energy storage device. By operating the rear-mounted pull rod assembly, the energy storage device can be easily moved to a designated location, or 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 using the energy storage device, which is conducive to improving the user experience of the energy storage device.

[0032] In addition, when the rear-mounted tie rod assembly is used to move the energy storage device, the rear-mounted support can provide reliable support for the energy storage device. Moreover, since the rear-mounted tie rod assembly is connected to both the rear-mounted support and the energy storage device, thus fixing the three together, it can prevent the energy storage device from falling off the support surface and being damaged during movement, which helps to improve the reliability of the energy storage device during movement.

[0033] In addition, in special scenarios, there may be some water accumulation on the balcony, or there may be rainwater outdoors. When the energy storage device is placed on a support surface, that is, a support base is set at the bottom of the energy storage device, it can play a certain waterproof role and help improve the overall reliability of the energy storage device.

[0034] Understandably, separating the rear-mounted tie rod assembly from the pre-installed connection structure of the energy storage device allows the energy storage device to be removed from the support surface.

[0055] 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.

[0056] 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.

[0057] The following reference Figures 1 to 15 This invention describes a rear-mounted mobile vehicle 100, an energy storage device 200, and a mobile energy storage system provided according to some embodiments of the present invention.

[0058] In one embodiment according to this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a rear-mounted mobile vehicle 100 is proposed. The rear-mounted mobile vehicle 100 is used for an energy storage device 200. The rear-mounted mobile vehicle 100 includes: a rear-mounted support base 120, which has a support surface 121 for accommodating the energy storage device 200; rear-mounted mobile wheels 130, which are located on the side of the rear-mounted support base 120 away from the support surface 121; and a rear-mounted tie rod assembly 140, which is located on the rear-mounted support base 120 and is used to be detachably connected to the connection structure 210 reserved in the energy storage device 200.

[0059] The rear-mounted mobile vehicle 100 provided in this embodiment of the utility model includes a rear-mounted support base 120, rear-mounted mobile wheels 130, and a rear-mounted pull rod assembly 140. Specifically, when it is necessary to change the placement position of the energy storage device 200, for example, moving it from an outdoor balcony to an indoor location, or when a user is carrying the energy storage device 200 during outdoor activities, the energy storage device 200 is placed on the support surface 121 of the rear-mounted support base 120, and the rear-mounted pull rod assembly 140 is connected to the pre-reserved connection structure 210 of the energy storage device 200. By operating the rear-mounted pull rod assembly 140, the energy storage device 200 can be easily moved to a designated position, 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 improving the user's experience of using the energy storage device 200.

[0060] In addition, when the rear-mounted tie rod assembly 140 moves the energy storage device 200, the rear-mounted support base 120 can provide reliable support for the energy storage device 200. Moreover, since the rear-mounted tie rod assembly 140 is connected to both the rear-mounted support base 120 and the energy storage device 200, thus fixing the three together, it can prevent the energy storage device 200 from falling off the support surface 121 and being damaged during movement, which helps to improve the reliability of the energy storage device 200 during movement.

[0061] In addition, in special scenarios, there may be some water accumulation on the balcony, or there may be rainwater outdoors. When the energy storage device 200 is placed on the support surface 121, that is, a support base is set at the bottom of the energy storage device 200, which can play a certain waterproofing role and help improve the overall reliability of the energy storage device 200.

[0062] Understandably, separating the rear-mounted tie rod assembly 140 from the reserved connection structure 210 of the energy storage device 200 allows the energy storage device 200 to be removed from the support surface 121.

[0063] In some embodiments, the rear-mounted caster 130 is optionally detachably connected to the rear-mounted support 120.

[0064] In this embodiment, since the rear-mounted moving wheel 130 and the rear-mounted support base 120 are detachable, the rear-mounted moving wheel 130 can be removed from the rear-mounted support base 120 when the energy storage device 200 is moved to a designated position or when the energy storage device 200 does not need to be moved.

[0065] Since the energy storage device 200 is placed on the support surface 121 of the rear-mounted support base 120, that is, the rear-mounted support base 120 is formed as a support structure for supporting the energy storage device 200, so that the energy storage device 200 is supported to a certain height. In the case of water accumulation in places such as balconies, it can play a certain waterproof role, which is conducive to improving the reliability of the energy storage device 200 and extending the service life of the energy storage device 200.

[0066] like Figure 5 As shown, in some embodiments, optionally, the rear support 120 has a hollow cavity 122 on the side opposite to the support surface 121.

[0067] In this embodiment, since the rear support 120 has a hollow cavity 122 on the side away from the support surface 121, the overall weight of the rear support 120 can be reduced while ensuring reliable support for the energy storage device 200, thereby achieving lightweighting of the rear mobile vehicle 100 and reducing the production cost of the rear mobile vehicle 100.

[0068] like Figure 6As shown, in some embodiments, optionally, the rear-mounted support base 120 includes a first layer plate 123 and a second layer plate 124, wherein the first layer plate 123 is provided with a support surface 121, the rear-mounted pull rod assembly 140 is provided on the first layer plate 123, the second layer plate 124 is provided on the side of the first layer plate 123 away from the support surface 121 and is rotatably connected to the first layer plate 123, and the rear-mounted moving wheel 130 is provided on the side of the second layer plate 124 away from the first layer plate 123.

[0069] In this embodiment, the rear-mounted support base 120 is defined to include a first layer plate 123 and a second layer plate 124. Specifically, the first layer plate 123 is provided with a support surface 121, and the rear-mounted tie rod assembly 140 is connected to the first layer plate 123. When the energy storage device 200 is placed on the support surface 121 and the rear-mounted tie rod assembly 140 is connected to the reserved connection structure 210 of the energy storage device 200, the first layer plate 123, the rear-mounted tie rod assembly 140 and the energy storage device 200 are fixed together.

[0070] Since the first plate 123 and the second plate 124 are rotatably connected, and the rear-mounted moving wheel 130 is set on the second plate 124, when the rear-mounted pull rod assembly 140 is operated to drive the energy storage device 200 to move, the rear-mounted pull rod assembly 140 can drive the energy storage device 200 to rotate relative to the second plate 124, which is beneficial to improving the flexibility and convenience of operating the rear-mounted pull rod assembly 140.

[0071] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 12 As shown, in some embodiments, optionally, the rear-mounted pull rod assembly 140 includes a pull rod rear mount 141, a connecting plate 142, and a rear-mounted connecting assembly 143, wherein the connecting plate 142 is disposed on the pull rod rear mount 141, at least one of the connecting plate 142 and the pull rod rear mount 141 is connected to the rear-mounted support 120, and the connecting plate 142 is detachably connected to the connecting structure 210 through the rear-mounted connecting assembly 143.

[0072] In this embodiment, the rear-mounted pull rod assembly 140 is defined as including a pull rod rear mount 141, a connecting plate 142, and a rear-mounted connecting assembly 143. Specifically, the connecting plate 142 is disposed on the pull rod rear mount 141, and the connecting plate 142 is connected to the rear-mounted support base 120. Alternatively, the pull rod rear mount 141 is connected to the rear-mounted support base 120, or both the connecting plate 142 and the pull rod rear mount 141 are connected to the rear-mounted support base 120. The specific configuration can be adjusted according to actual needs to achieve the assembly between the rear-mounted pull rod assembly 140 and the rear-mounted support base 120.

[0073] The connecting plate 142 is detachably connected to the connection structure 210 reserved in the energy storage device 200 through the rear-mounted connecting assembly 143. That is to say, the assembly between the tie rod rear-mount 141 and the energy storage device 200 can be realized through the connecting plate 142 and the rear-mounted connecting assembly 143. This ensures a reliable fit between the rear-mounted tie rod assembly 140 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 support surface 121. At the same time, the connecting plate 142 can be adjusted and replaced to accommodate tie rod rear-mount 141 of various forms and sizes, which helps to improve the flexibility and applicability of the assembly between the rear-mounted tie rod assembly 140 and the energy storage device 200.

[0074] Optionally, the rear-mounted connection assembly 143 includes a Torx screw, a snap-fit ​​structure, or a plunger structure.

[0075] Optionally, there are multiple rear-mounted connection components 143, with each connection structure 210 corresponding to a rear-mounted connection component 143. The multiple rear-mounted connection components 143 are distributed at intervals, which can improve the stability and reliability of the assembly between the rear-mounted tie rod assembly 140 and the energy storage device 200.

[0076] Optionally, the rear-mounted tie rod assembly 140 includes a tie rod rear mount 141 and screws. The tie rod rear mount 141 is directly connected to the connection structure 210 reserved in the energy storage device 200 by screws. Compared with setting a connection plate 142, this helps to reduce the cost of the energy storage device 200.

[0077] like Figure 3 , Figure 12 , Figure 14 and Figure 15 As shown, in some embodiments, optionally, the rear-mounted connection assembly 143 includes a first rear-mounted connection assembly 148, the first rear-mounted connection assembly 148 includes a first connector 211 and a second connector 160, wherein the first connector 211 is used to connect the connection structure 210, the second connector 160 is disposed on the connection plate 142, and the second connector 160 can cooperate with the first connector 211 to connect or separate.

[0078] In this embodiment, the first rear-mounted connection assembly 148 is defined to include a first connector 211 and a second connector 160. Specifically, the first connector 211 is connected to the connection structure 210, that is, the first connector 211 is fixed on the energy storage device 200. Optionally, the first connector 211 is connected to the connection structure 210 by screws.

[0079] Because the second connector 160 can be connected or disconnected 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 support surface 121, and the first connector 211 and the second connector 160 are connected to fix the rear-mounted pull rod assembly 140 on the energy storage device 200. By operating the rear-mounted pull rod assembly 140, the energy storage device 200 can be easily moved to the designated position by the rear-mounted moving wheels 130, which can also improve the reliability of the energy storage device 200 during the movement process.

[0080] Understandably, when the energy storage device 200 is moved to the designated position, the first connector 211 and the second connector 160 can be separated, allowing the energy storage device 200 to be removed from the support surface 121. By setting the first connector 211 and the second connector 160 to connect or separate, quick installation and disassembly between the rear-mounted tie rod assembly 140 and the energy storage device 200 can be achieved. This facilitates the movement of the energy storage device 200 while improving the efficiency of installation and disassembly between the rear-mounted tie rod assembly 140 and the energy storage device 200.

[0081] like Figure 12 As shown, in some embodiments, optionally, the first connector 211 includes a first buckle 212, and the second connector 160 includes a base 161 and a second buckle 162, wherein the base 161 is disposed on the connecting plate 142, and the second buckle 162 is movably disposed on the base 161, and the second buckle 162 is used to cooperate with the first buckle 212 for connection or separation.

[0082] In this embodiment, the second connector 160 is defined as including a base 161 and a second latch 162. Specifically, the base 161 is disposed on the connecting plate 142, and the second latch 162 is movably disposed on the base 161. That is, the second latch 162 is movably connected to the base 161, meaning that the second latch 162 can move relative to the base 161 to engage or disengage with the first latch 212. Optionally, the rear-mounted connecting assembly 143 is a snap-on structure.

[0083] By connecting or separating the first buckle 212 and the second buckle 162, the rear-mounted tie rod assembly 140 and the energy storage device 200 can be quickly installed and disassembled. This facilitates the movement of the energy storage device 200 and improves the efficiency of the installation and disassembly between the rear-mounted tie rod assembly 140 and the energy storage device 200.

[0084] like Figure 14 and Figure 15As shown, in some embodiments, optionally, the first connector 211 includes a limiting hole 213, and the second connector 160 includes a mounting part 163 and a limiting pin 164. The mounting part 163 is disposed on the connecting plate 142, and the limiting pin 164 is movably disposed on the mounting part 163. The limiting pin 164 is used to insert into or remove from the limiting hole 213.

[0085] In this embodiment, the second connector 160 is defined to include a mounting portion 163 and a limiting pin 164. Specifically, the mounting portion 163 is disposed on the connecting plate 142, and the limiting pin 164 is movably disposed on the mounting portion 163.

This is beneficial to further improve the assembly and disassembly efficiency between the rear-mounted tie rod assembly 140 and the energy storage device 200, reduce the difficulty of assembly and disassembly, and thus improve the user's experience with the energy storage device 200.

[0089] like Figure 13 As shown, in some embodiments, optionally, the connecting plate 142 includes a bent portion 144 located at the clearance opening 145, and the second connector 160 is disposed on the bent portion 144.

[0090] In this embodiment, the connecting plate 142 is defined to include a bent portion 144. Specifically, the bent portion 144 is disposed at the clearance opening 145, and the second connector 160 is disposed on the bent portion 144. Since at least part of the first connector 211 is exposed through the clearance opening 145, the second connector 160 is disposed on the bent portion 144 located at the clearance opening 145, which can reduce the difficulty of the second connector 160 and the first connector 211 in the fit, ensure the fit effect, and help to further improve the disassembly and assembly efficiency between the rear-mounted mobile vehicle 100 and the energy storage device 200.

[0091] Optionally, the bend 144 extends horizontally outward.

[0092] like Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, optionally, the connecting plate 142 is provided with a first connecting hole 146, the connecting structure 210 includes a second connecting hole 214; the rear-mounted connecting assembly 143 includes a second rear-mounted connecting assembly 147, which passes through the first connecting hole 146 and is detachably connected to the second connecting hole 214.

[0093] In this embodiment, the retrofit connection component 143 is defined to include a second retrofit connection component 147. Specifically, the connection structure 210 includes a second connection hole 214, that is, the connection structure 210 reserved on the energy storage device 200 is the second connection hole 214.

[0094] The connecting plate 142 is provided with a first connecting hole 146. The second rear-mounted connecting assembly 147 passes through the first connecting hole 146 and is detachably connected to the second connecting hole 214, thereby realizing the assembly between the rear-mounted pull rod assembly 140 and the energy storage device 200. While facilitating the movement of the energy storage device 200, it can improve the assembly and disassembly efficiency between the rear-mounted pull rod assembly 140 and the energy storage device 200.

[0095] Optionally, the second rear-mounted connection assembly 147 includes Torx screws.

[0096] According to a second aspect of the present invention, an energy storage device 200 is provided, including a connecting structure 210 for detachably connecting to a rear-mounted pull rod assembly 140 of a rear-mounted mobile vehicle 100. The rear-mounted mobile vehicle 100 includes a rear-mounted support base 120, rear-mounted mobile wheels 130, and a rear-mounted pull rod assembly 140. The rear-mounted support base 120 is provided with a support surface 121. Based on the separation of the connecting structure 210 from the rear-mounted pull rod assembly 140, the energy storage device 200 is detachably placed on the support surface 121. The rear-mounted mobile wheels 130 are located on the side of the rear-mounted support base 120 away from the support surface 121.

[0097] The energy storage device 200 provided in this embodiment includes a connecting structure 210. Specifically, the rear-mounted mobile vehicle 100 includes a rear-mounted support base 120, rear-mounted moving wheels 130, and a rear-mounted pull rod assembly 140. Specifically, when it is necessary to change the placement position of the energy storage device 200, for example, moving it from an outdoor balcony to an indoor location, or when a user is carrying the energy storage device 200 during outdoor activities, the energy storage device 200 is placed on the support surface 121 of the rear-mounted support base 120, and the rear-mounted pull rod assembly 140 is connected to the pre-reserved connecting structure 210 of the energy storage device 200. By operating the rear-mounted pull rod assembly 140, the energy storage device 200 can be easily moved to a designated position, or the energy storage device 200 can be easily dragged outdoors, improving the convenience of moving the energy storage device 200 and making it more time-saving and labor-saving for users when moving the energy storage device 200, which is conducive to improving the user's experience of using the energy storage device 200.

[0098] In addition, when the rear-mounted tie rod assembly 140 moves the energy storage device 200, the rear-mounted support base 120 can provide reliable support for the energy storage device 200. Moreover, since the rear-mounted tie rod assembly 140 is connected to both the rear-mounted support base 120 and the energy storage device 200, thus fixing the three together, it can prevent the energy storage device 200 from falling off the support surface 121 and being damaged during movement, which helps to improve the reliability of the energy storage device 200 during movement.

[0099] In addition, it is understandable that in special scenarios, there may be some water accumulation on the balcony, or there may be rainwater outdoors. When the energy storage device 200 is placed on the support surface 121, that is, a support base is set at the bottom of the energy storage device 200, which can play a certain waterproof role and help improve the overall reliability of the energy storage device 200.
