[0001] This utility model relates to the field of energy storage system technology, specifically to a retrofitted handcart, a balcony photovoltaic energy storage device, and an energy storage system. Background Technology

[0002] Currently, balcony photovoltaic energy storage systems are typically placed on the balconies of users' homes. During use, there are situations where it is necessary to move the energy storage system from outdoors to indoors or vice versa. In addition, when users are working or playing outdoors, they often carry energy storage systems because of the variety of electronic products they use, which consume power quickly. This is 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 at least solve one of the technical problems existing in the prior art.

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

[0006] A second aspect of the present invention provides a balcony photovoltaic energy storage device.

[0007] A third aspect of the embodiments of this utility model provides an energy storage system.

[0008] In view of the above, according to a first aspect of the present invention, a retrofit trolley is provided for use with a balcony photovoltaic energy storage device. The retrofit trolley includes: a pull rod retrofit component, which includes a retrofit pull rod, a retrofit adapter plate, and a retrofit connector. The retrofit adapter plate includes a plate body and a connecting portion. Along the height direction of the plate body, the connecting portion is located at at least one end of the plate body and connected to the retrofit pull rod. The retrofit connector is located on the plate body and is used to adapt to a first mating portion reserved for the balcony photovoltaic energy storage device. A retrofit caster assembly is also provided, which is used to adapt to a second mating portion reserved for the balcony photovoltaic energy storage device.

[0009] The rear-mounted handcart provided in this embodiment includes a rear-mounted pull rod and a rear-mounted caster assembly. Specifically, the rear-mounted adapter plate includes a plate body and a connecting portion, with the connecting portion located at at least one end of the plate body in the height direction. The connecting portion is connected to the rear-mounted pull rod, meaning the rear-mounted adapter plate is fixed to the rear-mounted pull rod via the connecting portion. Optionally, the connecting portion includes a threaded hole. Alternatively, the connecting portion includes a connecting plate with a threaded hole.

[0010] Because the retrofit connector is compatible with the first mating part reserved for the balcony photovoltaic energy storage device, the retrofit rod can be connected to the balcony photovoltaic energy storage device through the retrofit adapter plate and the retrofit connector. Furthermore, the retrofit caster assembly can be connected to the second mating part reserved for the balcony photovoltaic energy storage device, meaning the retrofit trolley can be installed onto the balcony photovoltaic energy storage device.

[0011] When it is necessary to change the placement of the balcony photovoltaic energy storage device, such as moving it from an outdoor balcony to an indoor location, or when the user is carrying the balcony photovoltaic energy storage device during outdoor activities, the rear-mounted pull rod can be operated to easily move the balcony photovoltaic energy storage device to the designated location, or to easily drag the balcony photovoltaic energy storage device outdoors, improving the convenience of moving the balcony photovoltaic energy storage device, making it more time-saving and labor-saving for users, and helping to improve the user experience of the balcony photovoltaic energy storage device.

[0012] Moreover, compared to the first mating part that directly connects the rear-mounted tie rod to the balcony photovoltaic energy storage device, using a rear-mounted adapter plate to install the tie rod to the balcony photovoltaic energy storage device allows for the adaptation of various types and sizes of rear-mounted tie rods by adjusting and replacing the adapter plate, which helps to improve the flexibility and applicability of the rear-mounted trolley.

[0013] In some technical solutions, the retrofit adapter plate may optionally include a reinforcing portion, which is located at at least one end of the plate body along the width direction of the plate body.

[0014] In this technical solution, by providing a reinforcing part at least one end in the width direction of the plate body, it is beneficial to improve the overall structural strength of the rear-mounted adapter plate, avoid deformation of the rear-mounted adapter plate during the installation and disassembly of the tie rod rear-mounted parts, extend the service life of the rear-mounted adapter plate, and reduce the maintenance cost of the rear-mounted handcart.

[0015] In some technical solutions, the reinforcing part optionally includes a first reinforcing section and a plurality of second reinforcing sections, wherein the first reinforcing section is connected to the plate body, and the plurality of second reinforcing sections are spaced apart at the end of the first reinforcing section away from the plate body.

[0016] This technical solution can reliably improve the overall structural strength of the retrofit adapter plate and prevent deformation of the retrofit adapter plate.

[0017] In some technical solutions, the rear-mounted adapter plate may optionally include a positioning part, which is located on at least one side of the plate body along the height direction of the plate body, and the two ends of the positioning part are respectively connected to the connecting part and the plate body; wherein, the rear-mounted tie rod includes a positioning surface, at least a portion of which is opposite to the positioning part and has a gap along the height direction of the plate body.

[0018] In this technical solution, since at least part of the positioning surface of the rear-mounted tie rod is opposite to the positioning part, the rear-mounted adapter plate can be initially positioned during installation, which helps improve the assembly efficiency of the tie rod's rear-mounted components. Furthermore, because there is a gap between the positioning surface and the positioning part—that is, a certain assembly gap is reserved between the rear-mounted tie rod and the rear-mounted adapter plate—it helps to further improve the assembly efficiency of the tie rod's rear-mounted components while reducing the machining precision of parts, thereby helping to reduce the production cost of balcony photovoltaic energy storage equipment.

[0019] In some technical solutions, optionally, the rear-mounted tie rod includes a first rod body, a second rod body, and a connecting beam, wherein the two ends of the connecting beam are connected to the first rod body and the second rod body respectively, the connecting part is connected to the connecting beam, and the connecting beam is provided with a positioning surface and a slot; the rear-mounted adapter plate also includes a limiting protrusion, which is provided on the connecting part and is at least partially inserted into the slot.

[0020] In this technical solution, the retrofit adapter plate also includes a limiting protrusion, which is set on the connecting part, and at least a part of the limiting protrusion is inserted into the slot of the connecting beam, thereby realizing the matching and limiting between the retrofit adapter plate and the retrofit tie rod. This is beneficial to improving the reliability of the matching between the retrofit adapter plate and the retrofit tie rod, and thus facilitates the reliable installation between the retrofit tie rod and the balcony photovoltaic energy storage equipment.

[0021] In some technical solutions, the plate body is optionally provided with a limiting groove, which is used to fit the flange reserved for the balcony photovoltaic energy storage equipment.

[0022] In this technical solution, when it is necessary to move the balcony photovoltaic energy storage device, the rear-mounted tie rod is connected to the balcony photovoltaic energy storage device through the rear-mounted connector and the rear-mounted adapter plate. At the same time, the flange reserved by the balcony photovoltaic energy storage device is inserted into the limiting groove of the plate body. This not only improves the ease of moving the balcony photovoltaic energy storage device, but also helps to improve the connection strength between the tie rod rear-mounted component and the balcony photovoltaic energy storage device, ensuring the stability and reliability when the tie rod rear-mounted component drives the balcony photovoltaic energy storage device to move.

[0023] In some technical solutions, optionally, the rear-mounted connector includes a first rear-mounted connector, which includes a first connector and a second connector. The first connector is used to connect the first mating part, and the second connector is disposed on the plate body. The second connector can be connected or separated from the first connector. The plate body is provided with a clearance opening, and at least a portion of the first connector is exposed through the clearance opening.

[0024] In this technical solution, by setting a first connector and a second connector, the rapid installation and disassembly of the tie rod rear-mounted component and the balcony photovoltaic energy storage device can be realized. This facilitates the movement of the balcony photovoltaic energy storage device and improves the efficiency of the installation and disassembly between the tie rod rear-mounted component and the balcony photovoltaic energy storage device.

[0025] In some technical solutions, optionally, the plate body is provided with a first connecting hole, the first mating part includes a second connecting hole, the rear-mounted connector includes a second rear-mounted connector, the second rear-mounted connector passes through the first connecting hole and is detachably connected to the second connecting hole.

[0026] This technical solution enables the assembly of the tie rod rear-mounted component with the balcony photovoltaic energy storage device, which facilitates the movement of the balcony photovoltaic energy storage device and improves the efficiency of disassembly and assembly between the tie rod rear-mounted component and the balcony photovoltaic energy storage device.

[0027] According to a second aspect of the present invention, a balcony photovoltaic energy storage device is provided, comprising: a first mating part for adapting to a rear-mounted connector of a rear-mounted trolley, the rear-mounted trolley including a pull rod rear-mounted component and a rear-mounted caster assembly, the pull rod rear-mounted component including a rear-mounted pull rod, a rear-mounted adapter plate and a rear-mounted connector, the rear-mounted adapter plate including a plate body and a connecting part, the connecting part being disposed at at least one end of the plate body along the height direction of the plate body and connected to the rear-mounted pull rod, and the rear-mounted connector being disposed on the plate body; and a second mating part for adapting to the rear-mounted caster assembly.

[0028] The balcony photovoltaic energy storage device provided in this embodiment includes a first mating part and a second mating part. Specifically, the rear-mounted trolley includes a pull rod rear-mounting component and a rear-mounted caster assembly. The rear-mounted adapter plate includes a plate body and a connecting part, with the connecting part located at at least one end in the height direction of the plate body. The connecting part is connected to the rear-mounted pull rod, meaning the rear-mounted adapter plate is fixed to the rear-mounted pull rod via the connecting part. Optionally, the connecting part includes a threaded hole. Alternatively, the connecting part includes a connecting plate with a threaded hole.

[0029] Because the retrofit connector is compatible with the first mating part reserved for the balcony photovoltaic energy storage device, the retrofit rod can be connected to the balcony photovoltaic energy storage device through the retrofit adapter plate and the retrofit connector. Furthermore, the retrofit caster assembly can be connected to the second mating part reserved for the balcony photovoltaic energy storage device, meaning the retrofit trolley can be installed onto the balcony photovoltaic energy storage device.

[0030] When it is necessary to change the placement of the balcony photovoltaic energy storage device, such as moving it from an outdoor balcony to an indoor location, or when the user is carrying the balcony photovoltaic energy storage device during outdoor activities, the rear-mounted pull rod can be operated to easily move the balcony photovoltaic energy storage device to the designated location, or to easily drag the balcony photovoltaic energy storage device outdoors, improving the convenience of moving the balcony photovoltaic energy storage device, making it more time-saving and labor-saving for users, and helping to improve the user experience of the balcony photovoltaic energy storage device.

[0031] Moreover, compared to the first mating part that directly connects the rear-mounted tie rod to the balcony photovoltaic energy storage device, using a rear-mounted adapter plate to install the tie rod to the balcony photovoltaic energy storage device allows for the adaptation of various types and sizes of rear-mounted tie rods by adjusting and replacing the adapter plate, which helps to improve the flexibility and applicability of the rear-mounted trolley.

[0032] According to a third aspect of this utility model, an energy storage system is provided, including a retrofitted handcart or balcony photovoltaic energy storage device as provided by any of the above technical solutions, and thus possesses all the beneficial technical effects of the retrofitted handcart or balcony photovoltaic energy storage device, which will not be repeated here.

[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 18 This invention describes a rear-mounted handcart 100, a balcony photovoltaic energy storage device 200, and an 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 , Figure 5 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 13 , Figure 17 and Figure 18As shown, a retrofit trolley 100 is proposed for use with a balcony photovoltaic energy storage device 200. The retrofit trolley 100 includes: a pull rod retrofit component 150, which includes a retrofit pull rod 110, a retrofit adapter plate 120, and a retrofit connector 130. The retrofit adapter plate 120 includes a plate body 121 and a connecting part 122. Along the height direction of the plate body 121, the connecting part 122 is located at at least one end of the plate body 121 and is connected to the retrofit pull rod 110. The retrofit connector 130 is located on the plate body 121 and is used to adapt to the first mating part 210 reserved in the balcony photovoltaic energy storage device 200; and a retrofit caster assembly 140, which is used to adapt to the second mating part 220 reserved in the balcony photovoltaic energy storage device 200.

[0059] The rear-mounted handcart 100 provided in this embodiment of the utility model includes a rear-mounted pull rod 150 and a rear-mounted caster assembly 140. Specifically, the rear-mounted adapter plate 120 includes a plate body 121 and a connecting portion 122, and the connecting portion 122 is disposed at at least one end in the height direction of the plate body 121. The connecting portion 122 is connected to the rear-mounted pull rod 110, that is, the rear-mounted adapter plate 120 is fixed to the rear-mounted pull rod 110 through the connecting portion 122. Optionally, the connecting portion 122 includes a threaded hole. Alternatively, the connecting portion 122 includes a connecting plate with a threaded hole.

[0060] Since the rear-mounted connector 130 is compatible with the first mating part 210 reserved on the balcony photovoltaic energy storage device 200, the rear-mounted pull rod 150 can be connected to the balcony photovoltaic energy storage device 200 through the rear-mounted adapter plate 120 and the rear-mounted connector 130. Furthermore, the rear-mounted caster assembly 140 can be connected to the second mating part 220 reserved on the balcony photovoltaic energy storage device 200, meaning the rear-mounted trolley 100 can be installed on the balcony photovoltaic energy storage device 200.

[0061] When the placement of the balcony photovoltaic energy storage device 200 needs to be changed, such as moving it from an outdoor balcony to an indoor location, or when the user is carrying the balcony photovoltaic energy storage device 200 during outdoor activities, the rear-mounted pull rod 110 can be operated to easily move the balcony photovoltaic energy storage device 200 to the designated location, or to easily drag the balcony photovoltaic energy storage device 200 outdoors, improving the convenience of moving the balcony photovoltaic energy storage device 200, making it more time-saving and labor-saving for users when moving the balcony photovoltaic energy storage device 200, and helping to improve the user experience of the balcony photovoltaic energy storage device 200.

[0062] Moreover, compared to directly connecting the rear-mounted pull rod 110 to the first mating part 210 of the balcony photovoltaic energy storage device 200, using the rear-mounted adapter plate 120 to realize the installation between the pull rod rear-mounted component 150 and the balcony photovoltaic energy storage device 200, the rear-mounted adapter plate 120 can be adjusted and replaced to adapt to various types and sizes of rear-mounted pull rods 110, which helps to improve the flexibility and applicability of the rear-mounted handcart 100.

[0063] Optionally, the rear-mounted caster assembly 140 can be separated from the second mating part 220. When the balcony photovoltaic energy storage device 200 is moved to a designated position, the rear-mounted caster assembly 140 can be removed from the balcony photovoltaic energy storage device 200, which helps to improve the stability of the balcony photovoltaic energy storage device 200 when it is fixed in a designated position and makes it convenient for users to use.

[0064] Optionally, the rear-mounted connector 130 and the first mating part 210 can be separated, that is, the rear-mounted rod 150 and the balcony photovoltaic energy storage device 200 can be detached. When the balcony photovoltaic energy storage device 200 does not need to be moved and during the use of the balcony photovoltaic energy storage device 200, the rear-mounted rod 150 can be removed from the balcony photovoltaic energy storage device 200, which can improve the heat dissipation effect of the balcony photovoltaic energy storage device 200 during operation, thereby helping to improve the reliability of the balcony photovoltaic energy storage device 200.

[0065] like Figure 3 and Figure 4 As shown, in some embodiments, the retrofit adapter plate 120 may optionally include a reinforcing portion 123, which is disposed at at least one end of the plate body 121 along the width direction of the plate body 121.

[0066] In this embodiment, the retrofit adapter plate 120 further includes a reinforcing portion 123. Specifically, the reinforcing portion 123 is disposed at one end of the plate body 121 along the width direction of the plate body 121, or the number of reinforcing portions 123 is two, and the two reinforcing portions 123 are respectively disposed at both ends of the plate body 121 along the width direction of the plate body 121. The specific configuration can be made according to actual needs.

[0067] By providing a reinforcing part 123 at at least one end of the plate body 121 in the width direction, it is beneficial to improve the overall structural strength of the rear-mounted adapter plate 120, avoid deformation of the rear-mounted adapter plate 120 during the installation and disassembly of the tie rod rear-mounted component 150, extend the service life of the rear-mounted adapter plate 120, and reduce the maintenance cost of the rear-mounted handcart 100.

[0068] Optionally, the reinforcing part 123 and the plate body 121 are an integral structure.

[0069] Optionally, the reinforcing part 123, the plate body 121, and the connecting part 122 are an integral structure.

[0070] Optionally, along the width direction of the plate body 121, there is an assembly gap between the reinforcing part 123 and the rear-mounted tie rod 110.

[0071] like Figure 3 and Figure 4 As shown, in some embodiments, optionally, the reinforcing part 123 includes a first reinforcing section 1231 and a plurality of second reinforcing sections 1232, wherein the first reinforcing section 1231 is connected to the plate body 121, and the plurality of second reinforcing sections 1232 are spaced apart at the end of the first reinforcing section 1231 away from the plate body 121.

[0072] In this embodiment, the reinforcing part 123 is defined to include a first reinforcing section 1231 and a plurality of second reinforcing sections 1232. Specifically, one end of the first reinforcing section 1231 is connected to the plate body 121, and the other end is provided with a plurality of second reinforcing sections 1232, thereby achieving a reliable improvement in the overall structural strength of the rear-mounted adapter plate 120 and avoiding deformation of the rear-mounted adapter plate 120.

[0073] like Figure 3 , Figure 4 and Figure 18 As shown, in some embodiments, optionally, the rear-mounted adapter plate 120 further includes a positioning part 125. Along the height direction of the plate body 121, the positioning part 125 is disposed on at least one side of the plate body 121, and the two ends of the positioning part 125 are respectively connected to the connecting part 122 and the plate body 121; wherein, the rear-mounted pull rod 110 includes a positioning surface 111. Along the height direction of the plate body 121, at least a portion of the positioning surface 111 is opposite to the positioning part 125 and has a gap.

[0074] In this embodiment, the retrofit adapter plate 120 further includes a positioning part 125. Specifically, along the height direction of the plate body 121, the positioning part 125 is disposed on at least one side of the plate body 121. Optionally, the positioning part 125 is disposed on the side of the plate body 121 near the top, or the positioning part 125 is disposed on the side of the plate body 121 near the bottom. Alternatively, there may be two positioning parts 125, disposed on opposite sides of the plate body 121 along the height direction. The specific configuration can be adjusted according to actual needs.

[0075] Since at least a portion of the positioning surface 111 of the rear-mounted tie rod 110 is opposite to the positioning part 125, the rear-mounted adapter plate 120 can be initially positioned during installation, which helps improve the assembly efficiency of the tie rod rear-mounted component 150. Furthermore, because there is a gap between the positioning surface 111 and the positioning part 125, i.e., a certain assembly gap is reserved between the rear-mounted tie rod 110 and the rear-mounted adapter plate 120, this further improves the assembly efficiency of the tie rod rear-mounted component 150 while reducing the machining precision of parts, thereby helping to reduce the production cost of the balcony photovoltaic energy storage device 200.

[0076] like Figure 5 and Figure 18 As shown, in some embodiments, optionally, the rear-mounted pull rod 110 includes a first rod 112, a second rod 113, and a connecting beam 114, wherein the two ends of the connecting beam 114 are respectively connected to the first rod 112 and the second rod 113, and the connecting part 122 is connected to the connecting beam 114. The connecting beam 114 is provided with a positioning surface 111 and a slot 115. The rear-mounted adapter plate 120 also includes a limiting protrusion 126, which is provided on the connecting part 122 and is at least partially inserted into the slot 115.

[0077] In this embodiment, the rear-mounted tie rod 110 includes a first rod body 112, a second rod body 113, and a connecting beam 114. Specifically, one end of the connecting beam 114 is connected to the first rod body 112, and the other end of the connecting beam 114 is connected to the second rod body 113, thereby realizing the assembly of the rear-mounted tie rod 110. Optionally, there are two connecting beams 114, which are arranged along the height direction of the plate body 121, and at least a portion of the plate body 121 is located between the two connecting beams 114. There are also two connecting parts 122, each connecting part 122 connecting one connecting beam 114. Since the connecting beam 114 is provided with a positioning surface 111, the initial positioning of the rear-mounted adapter plate 120 is achieved.

[0078] The rear-mount adapter plate 120 also includes a limiting protrusion 126, which is disposed on the connecting part 122. At least a portion of the limiting protrusion 126 is inserted into the slot 115 of the connecting beam 114, thereby realizing the matching and limiting between the rear-mount adapter plate 120 and the rear-mount tie rod 110. This helps to improve the reliability of the matching between the rear-mount adapter plate 120 and the rear-mount tie rod 110, and further facilitates the reliable installation between the tie rod rear-mount component 150 and the balcony photovoltaic energy storage device 200.

[0079] Optionally, there may be multiple limiting protrusions 126, with each slot 115 corresponding to a limiting protrusion 126.

[0080] like Figure 9 , Figure 10 , Figure 11 , Figure 14 and Figure 17 As shown, in some embodiments, optionally, the plate body 121 is provided with a limiting groove 127, which is used to adapt to the flange 230 reserved by the balcony photovoltaic energy storage device 200.

[0081] In this embodiment, the plate body 121 is provided with a limiting groove 127. Specifically, the limiting groove 127 can be adapted to the flange 230 reserved in the balcony photovoltaic energy storage device 200. That is to say, the flange 230 can be inserted into the limiting groove 127 to achieve limiting cooperation.

[0082] Specifically, when the balcony photovoltaic energy storage device 200 needs to be moved, the rear-mounted tie rod 110 is connected to the balcony photovoltaic energy storage device 200 through the rear-mounted connector 130 and the rear-mounted adapter plate 120. At the same time, the flange 230 reserved in the balcony photovoltaic energy storage device 200 is inserted into the limiting groove 127 of the plate body 121. This not only improves the ease of moving the balcony photovoltaic energy storage device 200, but also helps to improve the connection strength between the tie rod rear-mounted component 150 and the balcony photovoltaic energy storage device 200, ensuring the stability and reliability of the balcony photovoltaic energy storage device 200 when the tie rod rear-mounted component 150 is used to move it.

[0083] In addition, when the balcony photovoltaic energy storage device 200 is moved to a designated position, the rear-mounted connector 130 can be separated from the first mating part 210 reserved in the balcony photovoltaic energy storage device 200, and the flange 230 can be moved out of the limiting groove 127, thereby realizing the disassembly of the tie rod rear-mounted component 150 and the balcony photovoltaic energy storage device 200.
