Description

Optional accessories include handcarts, energy storage devices, and energy storage systems. Technical Field

[0001] This utility model relates to the field of energy storage system technology, and more specifically, to an optional handcart, energy storage equipment, and 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. Summary of the Invention

[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 an optional 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 an energy storage system.

[0008] In view of the above, according to a first aspect of the present invention, an optional handcart is provided for use with an energy storage device. The optional handcart includes: an optional pull rod assembly, which includes an optional pull rod and an optional connecting structure. The optional connecting structure is disposed on the optional pull rod and is used to be detachably connected to a first mounting structure reserved for the energy storage device; and optional moving wheels, which are used to be detachably connected to a second mounting structure reserved for the energy storage device. Based on the connection between the optional connecting structure and the first mounting structure, and the connection between the optional moving wheels and the second mounting structure, the optional pull rod can drive the energy storage device to move.

[0009] The optional trolley provided in this embodiment includes an optional pull rod assembly and optional casters. Specifically, the optional pull rod assembly includes an optional pull rod and an optional connecting structure. The optional connecting structure is located on the optional pull rod and is used to detachably connect to the first mounting structure reserved on the energy storage device. That is, the optional pull rod can be adapted to the first mounting structure on the energy storage device through the optional connecting structure. Moreover, the optional casters are used to adapt to the second mounting structure reserved on the energy storage device. In other words, the optional trolley can be installed on the energy storage device when it needs to be moved, and detached from the energy storage device when it does not need to be moved, using the optional pull rod assembly and optional casters.

[0010] 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 optional moving wheels are connected to the second mounting structure of the energy storage device, and the optional pull rod is connected to the first mounting structure of the energy storage device through the optional connecting structure. By operating the optional pull rod, the energy storage device can be moved to the designated location, or the energy storage device can be towed 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, which is conducive to improving the user experience of the energy storage device.

[0011] Furthermore, when the energy storage device is moved to a designated location, the optional moving wheels can be separated from the second mounting structure, and the optional connecting structure can be separated from the first mounting structure. This means the optional trolley can be removed from the energy storage device, which improves the stability of the device when fixed in the designated location and facilitates user operation. Moreover, when the energy storage device does not need to be moved and is in use, removing the optional trolley from the device improves heat dissipation during operation, thereby enhancing the reliability of the energy storage device.

[0012] In some technical solutions, the optional connection structure may include a tie rod fixing plate and a connector, wherein the tie rod fixing plate is fixed to the optional tie rod, and the tie rod fixing plate is detachably connected to the first mounting structure through the connector.

[0013] In this technical solution, the optional tie rod assembly and the energy storage device are assembled through a tie rod fixing plate. This ensures a reliable fit between the optional tie rod assembly and the energy storage device, while also allowing for the adaptation of various types and sizes of optional tie rods by adjusting and replacing the tie rod fixing plate. This improves the flexibility and applicability of assembling the optional trolley with the energy storage device.

[0014] In some technical solutions, optionally, the connector includes a first connector, which includes a first locking part and a second locking part. The first locking part is used to connect to the first mounting structure, and the second locking part is disposed on the tie rod fixing plate. The second locking part can cooperate with the first locking part to connect or separate.

[0015] In this technical solution, by setting a first locking part and a second locking part to connect or separate, the optional tie rod assembly and the energy storage device can be quickly installed and disassembled. This facilitates the movement of the energy storage device and improves the efficiency of the installation and disassembly between the optional tie rod assembly and the energy storage device.

[0016] In some technical solutions, optionally, the first locking part includes a first latch, and the second locking part includes a mounting base and a second latch, wherein the mounting base is disposed on the pull rod fixing plate, the second latch is movably disposed on the mounting base, and the second latch is used to engage or disengage with the first latch.

[0017] In this technical solution, by connecting or separating the first and second latches, the optional tie rod assembly and the energy storage device can be quickly installed and disassembled. This facilitates the movement of the energy storage device and improves the efficiency of the installation and disassembly between the optional tie rod assembly and the energy storage device.

[0018] In some technical solutions, optionally, the first locking part includes a mating hole, and the second locking part includes a mounting part and a locking pin, wherein the mounting part is disposed on the tie rod fixing plate, and the locking pin is movably disposed on the mounting part, and the locking pin is used to insert into or remove from the mating hole.

[0019] In this technical solution, by inserting or removing the locking pin from the mating hole, the optional tie rod assembly and the energy storage device can be quickly installed and disassembled. This facilitates the movement of the energy storage device and improves the efficiency of the installation and disassembly between the optional tie rod assembly and the energy storage device.

[0020] In some technical solutions, optionally, the first locking part includes a connecting part and a mating part. The connecting part is used to connect to the first mounting structure, and the mating part is connected to the connecting part. The mating part is provided with a mating hole. The tie rod fixing plate includes a mounting plate. The mounting plate extends away from the first mounting structure and is at least partially opposite to the mating part. The mounting part is disposed on the mounting plate.

[0021] In this technical solution, specifically during the installation of the optional tie rod assembly, the locking pin is first pulled down. Once the locking pin aligns with the mating hole, it is released, causing the locking pin to move upward and insert into the mating hole, thus achieving rapid assembly between the optional tie rod assembly and the energy storage device. It is understood that for disassembly, simply pulling down the locking pin again and removing the optional tie rod assembly allows for quick removal.

[0022] In some technical solutions, the first locking part may optionally include a protective reinforcement part, which is connected to the end of the mating part away from the connecting part and is at least partially opposite to the connecting part.

[0023] In this technical solution, on the one hand, by setting a protective reinforcement, the structural strength of the first locking part can be effectively improved, preventing deformation of the first locking part during assembly and disassembly, and ensuring reliable engagement between the first and second locking parts. On the other hand, by setting a protective reinforcement at the end of the mating part away from the connecting part, the risk of injury from direct contact with the edge of the mating part can be reduced during the installation or disassembly of the pull rod assembly, thus improving the safety of using the optional handcart.

[0024] In some technical solutions, optionally, the tie rod fixing plate includes a first connecting hole, the first mounting structure includes a second connecting hole, and the connector includes a second connector that passes through the first connecting hole and is detachably connected to the second connecting hole.

[0025] This technical solution enables the assembly of optional tie rod components with energy storage devices, which facilitates the movement of energy storage devices and improves the efficiency of disassembly and assembly between the optional tie rod components and energy storage devices.

[0026] According to a second aspect of the present invention, an energy storage device is provided, comprising: a first mounting structure for detachably connecting to an optional connecting structure of an optional trolley, the optional trolley including an optional pull rod assembly and optional moving wheels, the optional pull rod assembly including an optional pull rod and an optional connecting structure, the optional connecting structure being disposed on the optional pull rod; and a second mounting structure for detachably connecting to the optional moving wheels.

[0027] The energy storage device provided in this embodiment includes a first mounting structure and a second mounting structure. Specifically, the optional pull rod assembly includes an optional pull rod and an optional connecting structure. The optional connecting structure is located on the optional pull rod and is used to detachably connect to the first mounting structure reserved on the energy storage device. In other words, the optional pull rod can be adapted to the first mounting structure on the energy storage device through the optional connecting structure. Furthermore, optional casters are used to adapt to the second mounting structure reserved on the energy storage device. That is, the optional trolley can be installed on the energy storage device when it needs to be moved, and removed from the energy storage device when it does not need to be moved, using the optional pull rod assembly and optional casters.

[0028] 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 optional moving wheels are connected to the second mounting structure of the energy storage device, and the optional pull rod is connected to the first mounting structure of the energy storage device through the optional connecting structure. By operating the optional pull rod, the energy storage device can be moved to the designated location, or the energy storage device can be towed 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, which is conducive to improving the user experience of the energy storage device.

[0029] Furthermore, when the energy storage device is moved to a designated location, the optional moving wheels can be separated from the second mounting structure, and the optional connecting structure can be separated from the first mounting structure. This means the optional trolley can be removed from the energy storage device, which improves the stability of the device when fixed in the designated location and facilitates user operation. Moreover, when the energy storage device does not need to be moved and is in use, removing the optional trolley from the device improves heat dissipation during operation, thereby enhancing the reliability of the energy storage device.

[0030] According to a third aspect of this utility model, an energy storage system is provided, including an optional trolley or energy storage device as provided in any of the above technical solutions, and thus possesses all the beneficial technical effects of the optional trolley or energy storage device, which will not be repeated here.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0054] 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.

[0055] The optional handcart 100, energy storage device 200 and energy storage system provided according to some embodiments of the present invention are described below with reference to Figures 1 to 18.

[0056] In one embodiment of this application, as shown in Figures 1, 2, 8, 9, 13, 17, and 18, an optional handcart 100 is proposed for use with an energy storage device 200. The optional handcart 100 includes: an optional pull rod assembly 120, which includes an optional pull rod 122 and an optional connecting structure 123. The optional connecting structure 123 is disposed on the optional pull rod 122 and is used to be detachably connected to a first mounting structure 210 reserved in the energy storage device 200; and optional casters 110, which are used to be detachably connected to a second mounting structure 220 reserved in the energy storage device 200. Based on the connection between the optional connecting structure 123 and the first mounting structure 210, and the connection between the optional casters 110 and the second mounting structure 220, the optional pull rod 122 can drive the energy storage device 200 to move.

[0057] The optional trolley 100 provided in this embodiment of the utility model includes an optional pull rod assembly 120 and optional casters 110. Specifically, the optional pull rod assembly 120 includes an optional pull rod 122 and an optional connecting structure 123. The optional connecting structure 123 is disposed on the optional pull rod 122 and is used to detachably connect to the first mounting structure 210 reserved on the energy storage device 200. That is, the optional pull rod 122 can be adapted to the first mounting structure 210 on the energy storage device 200 through the optional connecting structure 123. Moreover, the optional casters 110 are used to adapt to the second mounting structure 220 reserved on the energy storage device 200. In other words, the optional trolley 100 can be installed on the energy storage device 200 when it needs to be moved, and detached from the energy storage device 200 when it does not need to be moved, through the optional pull rod assembly 120 and the optional casters 110.

[0058] Specifically, when the placement of the 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 energy storage device 200 during outdoor activities, the optional moving wheels 110 are connected to the second mounting structure 220 of the energy storage device 200, and the optional pull rod 122 is connected to the first mounting structure 210 of the energy storage device 200 through the optional connecting structure 123. By operating the optional pull rod 122, the energy storage device 200 can be moved to a designated location, or the energy storage device 200 can be towed 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.

[0059] Furthermore, when the energy storage device 200 is moved to a designated location, the optional moving wheels 110 can be separated from the second mounting structure 220, and the optional connecting structure 123 can be separated from the first mounting structure 210, that is, the optional trolley 100 can be removed from the energy storage device 200. This helps improve the stability of the energy storage device 200 when it is fixed in a designated location, making it easier for users to use. Moreover, when the energy storage device 200 does not need to be moved, and during the use of the energy storage device 200, removing the optional trolley 100 from the energy storage device 200 can improve the heat dissipation effect of the energy storage device 200 during operation, thereby helping to improve the reliability of the energy storage device 200.

[0060] Optionally, the second mounting structure 220 is located at the bottom of the energy storage device 200, that is, the optional casters 110 are installed at the bottom of the energy storage device 200. Optionally, the number of optional casters 110 is multiple.

[0061] As shown in Figures 1, 2, 3, 4, 5, 8, 9, 10, 11, 12, 13, 14, 15, 16, and 17, in some embodiments, the optional connecting structure 123 may optionally include a tie rod fixing plate 130 and a connector 140, wherein the tie rod fixing plate 130 is fixed to the optional tie rod 122, and the tie rod fixing plate 130 is detachably connected to the first mounting structure 210 through the connector 140.

[0062] In this embodiment, the optional connection structure 123 is defined to include a pull rod fixing plate 130 and a connector 140. Specifically, the pull rod fixing plate 130 is fixedly connected to the optional pull rod 122, and the pull rod fixing plate 130 is detachably connected to the first mounting structure 210 reserved in the energy storage device 200 through the connector 140. That is to say, the assembly between the optional pull rod assembly 120 and the energy storage device 200 is realized through the pull rod fixing plate 130. Thus, while achieving reliable cooperation between the optional pull rod assembly 120 and the energy storage device 200, the pull rod fixing plate 130 can be adjusted and replaced to adapt to various forms and sizes of optional pull rods 122, which is beneficial to improving the flexibility and applicability of the assembly between the optional trolley 100 and the energy storage device 200.

[0063] Alternatively, the connector 140 may include a Torx screw, a snap-fit ​​mechanism, or a plunger mechanism.

[0064] Optionally, there may be multiple connectors 140, which are spaced apart to improve the stability and reliability of the assembly between the optional tie rod assembly 120 and the energy storage device 200.

[0065] Optionally, the optional connection structure 123 includes an optional tie rod 122 and screws. That is, the optional tie rod 122 is directly connected to the first mounting structure 210 reserved in the energy storage device 200 by screws. Compared with setting the tie rod fixing plate 130, this helps to reduce the cost of the energy storage device 200.

[0066] Figures 1 to 7 illustrate the first embodiment of this application. As shown in Figures 1, 2, 3, 4, 5, 6, and 7, in some embodiments, optionally, the tie rod fixing plate 130 includes a first connecting hole 133, the first mounting structure 210 includes a second connecting hole 218, and the connector 140 includes a second connector 141, which passes through the first connecting hole 133 and is detachably connected to the second connecting hole 218.

[0067] In this embodiment, the first mounting structure 210 is defined to include a second connecting hole 218, that is, the structure reserved on the energy storage device 200 is the second connecting hole 218. The connector 140 includes a second connector 141, which passes through the first connecting hole 133 and connects to the second connecting hole 218, thereby realizing the assembly between the optional tie rod assembly 120 and the energy storage device 200. While facilitating the movement of the energy storage device 200, it can also improve the efficiency of disassembly and assembly between the optional tie rod assembly 120 and the energy storage device 200.

[0068] Optionally, the second connector 141 includes a Torx screw.

[0069] As shown in Figures 3, 4, and 18, in some embodiments, optionally, the tie rod fixing plate 130 includes an adapter plate 135 and a first positioning surface 136, wherein the adapter plate 135 is detachably connected to the first mounting structure 210 via a connector 140, and the first positioning surface 136 is disposed on at least one side of the adapter plate 135 along the length direction of the optional tie rod 122; wherein the optional tie rod 122 includes a second positioning surface 124, and at least a portion of the second positioning surface 124 is opposite to the first positioning surface 136 along the length direction of the optional tie rod 122, and there is a gap between the second positioning surface 124 and the first positioning surface 136.

[0070] In this embodiment, the tie rod fixing plate 130 is defined as including an adapter plate 135 and a first positioning surface 136. Specifically, along the length direction of the optional tie rod 122, the first positioning surface 136 is disposed on at least one side of the adapter plate 135. Optionally, the first positioning surface 136 is disposed on the side of the adapter plate 135 near the top, or the first positioning surface 136 is disposed on the side of the adapter plate 135 near the bottom. Alternatively, there may be two first positioning surfaces 136, disposed on opposite sides of the adapter plate 135 along the length direction of the optional tie rod 122. The specific configuration can be adjusted according to actual needs.

[0071] Since at least a portion of the second positioning surface 124 of the optional tie rod 122 is opposite to the first positioning surface 136, the tie rod fixing plate 130 can be initially positioned during installation, which helps improve the assembly efficiency between the optional tie rod assembly 120 and the energy storage device 200. Furthermore, since there is a gap between the second positioning surface 124 and the first positioning surface 136, i.e., a certain assembly gap is reserved between the optional tie rod 122 and the tie rod fixing plate 130, this further improves the assembly efficiency between the optional tie rod assembly 120 and the energy storage device 200 while reducing the machining precision of parts, thereby helping to reduce the production cost of the energy storage device 200.

[0072] As shown in Figures 3, 4 and 5, optionally, the tie rod fixing plate 130 also includes a reinforcing plate 137. Along the width direction of the optional tie rod 122, the reinforcing plate 137 is disposed at at least one end of the adapter plate 135, which helps to improve the overall structural strength of the tie rod fixing plate 130, avoids deformation of the tie rod fixing plate 130 during the installation and disassembly of the optional tie rod assembly 120, and helps to extend the service life of the tie rod fixing plate 130.

[0073] As shown in Figures 3, 4 and 5, in some embodiments, the pull rod fixing plate 130 may optionally include a plug portion 138, and the optional pull rod 122 includes a slot 125, with at least a portion of the plug portion 138 inserted into the slot 125.

[0074] In this embodiment, the tie rod fixing plate 130 is further defined as including a plug-in portion 138. Specifically, the optional tie rod 122 includes a slot 125, and at least part of the plug-in portion 138 is inserted into the slot 125, thereby realizing the matching and limiting between the tie rod fixing plate 130 and the optional tie rod 122. This is beneficial to improving the reliability of the matching between the tie rod fixing plate 130 and the optional tie rod 122, and thus facilitates the reliable installation between the optional tie rod assembly 120 and the energy storage device 200.

[0075] Optionally, there may be multiple plug-in portions 138, with each slot 125 corresponding to a plug-in portion 138.

[0076] Optionally, the optional tie rod 122 includes a first tie rod, a second tie rod, and a connecting beam. The two ends of the connecting beam are connected to the first tie rod and the second tie rod, respectively, and the slot 125 is provided on the connecting beam.

[0077] Figures 8 to 17 illustrate the second and third embodiments of this application. As shown in Figures 8, 9, 10, 11, 12, 13, 14, 15, 16, and 17, in some embodiments, optionally, the connector 140 includes a first connector 142, the first connector 142 including a first locking part 211 and a second locking part 160, wherein the first locking part 211 is used to connect to the first mounting structure 210, and the second locking part 160 is disposed on the pull rod fixing plate 130, and the second locking part 160 can cooperate with the first locking part 211 to connect or separate.

[0078] In this embodiment, the connector 140 is defined to include a first connector 142, wherein the first connector 142 includes a first locking part 211 and a second locking part 160. The first locking part 211 is connected to the first mounting structure 210, that is, the first locking part 211 is fixed on the energy storage device 200.

[0079] Since the second locking part 160 can be connected or separated from the first locking part 211, specifically, when it is necessary to move the energy storage device 200, the optional moving wheel 110 is connected to the second mounting structure 220 reserved on the energy storage device 200, and the first locking part 211 and the second locking part 160 are connected to fix the optional pull rod assembly 120 and the optional moving wheel 110 on the energy storage device 200. By operating the optional pull rod assembly 120, the energy storage device 200 can be easily moved to the designated position.

[0080] When the energy storage device 200 is moved to a designated location, the first locking part 211 and the second locking part 160 can be separated to detach the optional pull rod assembly 120 from the energy storage device 200. By setting the first locking part 211 and the second locking part 160 to connect or separate, quick installation and removal between the optional pull rod assembly 120 and the energy storage device 200 can be achieved. This facilitates the movement of the energy storage device 200 and improves the efficiency of installation and removal between the optional pull rod assembly 120 and the energy storage device 200.

[0081] Figures 8 to 12 illustrate the second embodiment of this application. As shown in Figures 8, 9, and 12, in some embodiments, optionally, the first locking part 211 includes a first latch 212, and the second locking part 160 includes a mounting base 161 and a second latch 162. The mounting base 161 is disposed on the pull rod fixing plate 130, and the second latch 162 is movably disposed on the mounting base 161. The second latch 162 is used to engage or disengage with the first latch 212.

[0082] In this embodiment, the second locking part 160 includes a mounting base 161 and a second latch 162. Specifically, the mounting base 161 is disposed on the pull rod fixing plate 130, and the second latch 162 is movably disposed on the mounting base 161. That is, the second latch 162 is movably connected to the mounting base 161, meaning that the second latch 162 can move relative to the mounting base 161 to engage or disengage with the first latch 212. Optionally, the connector 140 is a snap-on structure.

That is, one end of the mating part 216 is connected to the connecting part 215, and the other end of the mating part 216 is connected to the protective reinforcement part 217. At least a portion of the protective reinforcement part 217 is opposite to the connecting part 215. On the one hand, by providing the protective reinforcement part 217, the structural strength of the first locking part 211 can be effectively improved, preventing the first locking part 211 from deforming during disassembly and assembly, and ensuring a reliable fit between the first locking part 211 and the second locking part 160.

[0095] On the other hand, a protective reinforcement part 217 is provided at the end of the mating part 216 away from the connecting part 215. During the process of installing or disassembling the pull rod assembly, the risk of injury caused by the user directly contacting the edge of the mating part 216 can be reduced, which helps to improve the safety of using the optional handcart 100.

[0096] Optionally, the protective reinforcement 217, the mating part 216, and the connecting part are an integral structure.

[0097] As shown in Figures 10, 11 and 14, in some embodiments, the pull rod fixing plate 130 optionally includes a clearance opening 132 through which at least a portion of the first locking portion 211 is exposed.

[0098] In this embodiment, the tie rod fixing plate 130 is defined to include a clearance opening 132. Specifically, at least a portion of the first locking part 211 is exposed through the clearance opening 132, which facilitates the engagement or disengagement between the second locking part 160 and the first locking part 211. This is beneficial to further improve the assembly and disassembly efficiency between the optional tie rod assembly 120 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.

[0099] As shown in Figures 10, 11, 14 and 17, in some embodiments, the tie rod fixing plate 130 may optionally include a first limiting part 134, which is used to connect or separate from the second limiting part 230 reserved in the energy storage device 200.

[0102] Understandably, when the energy storage device 200 is moved to a designated location, the connector 140 can be separated from the first mounting structure 210, and at the same time, the first limiting part 134 can be separated from the second limiting part 230, thereby removing the optional pull rod assembly 120 from the energy storage device 200.

[0103] Optionally, one of the first limiting part 134 and the second limiting part 230 is a groove and the other is a flange, and the flange can be inserted into the groove.

[0104] According to a second aspect of the present invention, an energy storage device 200 is provided, comprising: a first mounting structure 210 for detachably connecting to an optional connecting structure 123 of an optional trolley 100, the optional trolley 100 including an optional pull rod assembly 120 and optional moving wheels 110, the optional pull rod assembly 120 including an optional pull rod 122 and an optional connecting structure 123, the optional connecting structure 123 being disposed on the optional pull rod 122; and a second mounting structure 220 for detachably connecting to the optional moving wheels 110.
