DETAILED DESCRIPTION

[0040] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0041] Please refer to Figures 1 to 11 , the embodiment provides a stacked energy storage device, comprising a power host 1, the power host 1 is detachably assembled with an energy storage assembly 2 below, the energy storage assembly 2 comprises at least one energy storage unit device 21, the energy storage unit device 21 is provided with a connecting mechanism 211, the connecting mechanism 211 is used to realize detachable assembly with the power host 1, and can also be used to stack and assemble any two adjacent energy storage unit devices 21 to expand the power demand.

[0042] ​​​​In the embodiment, the power supply host 1 is the core control and key part of the whole energy storage device for power output and input, has corresponding circuit control module, external connection port and other conventional components, is used for managing and regulating the whole energy storage and power supply process and performing electrical energy interaction with external devices. Specifically, the energy storage assembly 2 is composed of three energy storage unit devices 21, each of which adopts high-performance lithium ion battery or other suitable energy storage medium to ensure efficient and stable power output. It should be noted that the number of energy storage unit devices 21 can be set according to actual needs. Each energy storage unit device 21 is generally in the shape of a cuboid. The connecting mechanism 211 provided on the energy storage unit device 21 can adopt mechanical lock, sliding rail and sliding groove cooperation, clamping groove and clamping buckle cooperation, or other mechanical connection structures. When the energy storage assembly 2 needs to be assembled, the energy storage unit device 21 is firmly connected with the power supply host 1 through the connecting mechanism 211, so that the energy storage unit device 21 can stably cooperate with the power supply host 1 to prepare for subsequent electrical energy transmission and storage. When any two adjacent energy storage unit devices 21 are stacked and assembled to expand the power demand, the connecting mechanism 211 on the top of the lower energy storage unit device 21 can be fixed with the bottom of the upper energy storage unit device 21, and by stacking a plurality of energy storage unit devices 21 in sequence, the energy storage capacity of the whole stacked energy storage device can be conveniently increased to meet the expansion of power demand in different scenarios. For example, when a large number of electronic devices, lighting devices and the like need to be powered for a long time in an outdoor large-scale activity site, the power consumption demand can be easily met by increasing the number of stacked energy storage unit devices 21, thereby ensuring the smooth progress of the activity. The connecting mechanism 211 enables the energy storage unit device 21 to be detachably assembled with the power supply host 1 and the energy storage unit devices 21 to be stacked and assembled, so that the whole stacked energy storage device can flexibly increase or decrease the number of energy storage unit devices 21 according to the actual power demand of the use scene. Users do not need to purchase multiple sets of energy storage devices with different specifications and capacities, which greatly reduces the use cost and improves the versatility and applicability of the device. The stacked design makes full use of the space in the vertical direction, reduces the occupied area, and is particularly suitable for use in places with limited space.

[0043] Further, as a preferred embodiment but not a limitation of the present scheme, the connecting mechanism 211 includes a connecting piece 2111 provided on one side of the energy storage unit device 21, which can be used to connect the power supply host 1 and can also be used to connect any two adjacent energy storage unit devices 21; a positioning piece 2112 provided on the other side of the energy storage unit device 21, which can be used to connect and position the power supply host 1 and can also be used to position and connect any two adjacent energy storage unit devices 21.

[0044] In the embodiment, the connecting piece 2111 can be designed as a plug-in type, a threaded type or a buckle type, etc. to adapt to different connection requirements. Specifically, the connecting piece 2111 can be a specially designed metal connecting plate, the surface of which is provided with a threaded hole, and a corresponding mounting hole is formed on one side of the energy storage unit device 21, and the partial area of the connecting piece 2111 is fixed to the mounting hole on the energy storage unit device 21 through a threaded fastener. When connected with the power main machine 1, the corresponding side position of the power main machine 1 is provided with a threaded hole matched with the connecting piece 2111, and when it is necessary to assemble the energy storage unit device 21 to the lower side of the power main machine 1, only the connecting piece 2111 on the energy storage unit device 21 needs to be aligned with the threaded hole of the power main machine 1, and then the threaded fastener is installed to achieve the firm connection of the two, so as to ensure that the electric energy can be stably transmitted from the energy storage unit device 21 to the power main machine 1 for distribution and external output.

[0045] Similarly, when the adjacent two energy storage unit devices 21 are stacked and assembled, the connecting piece 2111 on the side of the lower energy storage unit device 21 can be connected with the corresponding matching hole reserved on the corresponding side of the bottom of the upper energy storage unit device 21 through a threaded fastener, so that the two energy storage unit devices 21 can be reliably connected together.

[0046] The positioning piece 2112 is arranged on the other side of the energy storage unit device 21 opposite to the connecting piece 2111. Since it is designed as a specific shape with a limited positioning effect, it has a connecting function while providing additional positioning effect. Like the connecting piece 2112, it can also be fixed and assembled with the power main machine 1 and the energy storage unit device 21 in a threaded connection manner. The arrangement of the positioning piece 2112 enables the energy storage unit device 21, the power main machine 1 and the energy storage unit devices 21 to be quickly and accurately positioned during assembly, greatly improving the installation efficiency. At the same time, during the operation of the equipment, the stable relative positions between the components can be maintained, so that the electric energy transmission is not affected even in complex use environments such as vibration and shaking, reducing the electrical fault hidden dangers that may be caused by position deviation, and improving the overall reliability and safety of the equipment. In addition, the positioning piece 2112 and the positioning piece 2112 work together to achieve convenient and quick connection and disassembly operation, while ensuring the stability of the entire stacked energy storage equipment structure and the smoothness of electric power transmission from different aspects.

When connecting the power host 1 and the energy storage unit 21, the user only needs to align the second slot 212 of the energy storage unit 21 with the first slot 11 of the power host 1, and press the positioning member 2112 against the two slots, and finally connect by screwing the threaded fasteners. Since the positioning member 2112 matches the shape of the slot, the accuracy and stability of the connection can be ensured. The same applies to the assembly of the positioning member 2112 between two adjacent energy storage units 21, which will not be described here.

[0049] Since the positioning member 2112 completely matches the shape of the first slot 11 and the second slot 212, the accurate connection between the energy storage unit 21 and the power host 1 and the adjacent energy storage unit 21 can be ensured. This avoids the problem of unstable power transmission or equipment damage due to inaccurate connection position.

[0050] Further, as a preferred but non-limiting embodiment of the present application, the first slot 11 and the second slot 212 are straight slots provided along the corners.

The design of the straight slot simplifies the cooperation between the positioning member 2112 and the slot, making the connection process simpler and more convenient. In addition, it also makes the installation and maintenance of the energy storage unit 21 simpler and more convenient. When installing, the user only needs to align the slot of the upper device with the positioning member 2112 to achieve quick positioning and connection, without the need for complex operation steps or tools.

By holding the handle, the user can better control the moving direction and speed of the equipment, to avoid accidental collision or tipping over.

[0054] Further, as a preferred embodiment of the present scheme but not limited, the side of the energy storage unit device 21 opposite to the second slot 212 is provided with a lifting handle position 213 for facilitating carrying, and the horizontal position of the lifting handle position 213 corresponds to that of the second handle 2121. The lifting handle position 213 can be used in cooperation with the second handle 2121, to further enhance the safety and stability of the energy storage unit device 21 during carrying or installation.

By effective heat dissipation, the temperature inside the equipment can be reduced, to reduce faults and damages caused by overheating. At the same time, the protection of the heat dissipation cover 2141 can also prevent dust, debris, and other foreign matters from entering the inside of the equipment, to maintain the cleanliness and stable operation of the equipment.

[0056] Further, as a preferred embodiment of the present scheme but not limited, the first slot 11 is provided with a first electrical interface 112, the second slot 212 is provided with a second electrical interface 2122 corresponding to the first electrical interface 112 for electrical connection, and the second electrical interface 2122 is further provided with a third electrical interface 2123 below, which can be electrically connected with the second electrical interface 2122 on the adjacent energy storage unit device 21.
