When installing a battery energy storage cabinet at home, it is necessary to arbitrarily allocate the battery energy storage cabinet according to the size of the house space, while the integrated structure battery energy storage cabinet is not suitable for houses of different sizes and cannot be used in ordinary families; secondly, when the battery energy storage cabinet adopts a splicing structure, affected by the weight of the battery itself, when the assembled battery energy storage cabinet has a certain height, it is inconvenient to access the upper-layer batteries because the problems during the access operation of the battery energy storage cabinet need to be solved; secondly, the above-mentioned battery energy storage cabinet does not have a multiple combination structure, and its single battery structure has a certain weight and cannot be used in any size of battery structure according to needs, thus reducing the versatility of the battery energy storage cabinet and having a single function. Summary of the Invention

[0005] The purpose of the present invention is to provide a multi-purpose household backup battery energy storage cabinet, which can solve the existing problems.

[0006] The problems solved by the present invention are:

[0007] 1. The inability to perform two-way combined fixing operations reduces the flexibility during the use of the battery energy storage cabinet. When installing a battery energy storage cabinet in a household, it is necessary to arbitrarily allocate the battery energy storage cabinet according to the size of the house space. However, the battery energy storage cabinet with an integrated structure is not suitable for houses of different sizes and cannot be used in ordinary families.

[0008] 2. Secondly, when the battery energy storage cabinet adopts a splicing structure, affected by the weight of the battery itself, when the assembled battery energy storage cabinet reaches a certain height, it is inconvenient to access the batteries on the upper layer because the problems during the access operation of the battery energy storage cabinet need to be solved.

[0009] 3. Secondly, the above-mentioned battery energy storage cabinet does not have a multi-combination structure. Its single battery structure has a certain weight and cannot be used in any battery structure of arbitrary size according to requirements, thus reducing the versatility of the battery energy storage cabinet and having a single function.

[0010] The object of the present invention can be achieved by the following technical solutions:

[0011] A multi-purpose household backup battery energy storage cabinet includes several groups of first battery compartments and second battery compartments. The first battery compartments are spliced and installed on the outer surface of one side of the second battery compartments. The first battery compartments and the second battery compartments are spliced and fixed through two-way connectors. Several groups of first battery compartments and several groups of second battery compartments are all arranged in a vertical stack. Battery boxes are arranged inside both the first battery compartments and the second battery compartments. Several groups of battery blocks are installed inside the battery boxes. A lifting frame for accessing the battery boxes is movably installed at the front ends of the first battery compartments and the second battery compartments. A power-taking sliding plate is movably installed inside the lifting frame. Charging seats are arranged at the lower ends of the bottom first battery compartments and second battery compartments.

During stacked assembly, the first battery compartments and the second battery compartments are installed sequentially from top to bottom, allowing the splicing frames below to be inserted into the clamping grooves above to complete the stacking operation of the first battery compartments and the second battery compartments. During side-by-side assembly, it is necessary to cooperate with the two-way connectors. The two-way connectors can be used to assemble the first battery compartments and the second battery compartments side by side, fixing the first battery compartments on one side of the second battery compartments and enabling the assembled first battery compartments and second battery compartments to be connected in series and energized.

[0013] As a further technical solution of the present invention, two groups of elastic folding plates are provided at the front ends of the first battery compartment and the second battery compartment. Ejecting members are installed inside both the first battery compartment and the second battery compartment. Ventilation grooves are provided in the first battery compartment, the second battery compartment, and the charging base. After the first battery compartment, the second battery compartment, and the charging base are assembled with each other, by using the ventilation grooves in cooperation with the fan in the charging base, synchronous heat dissipation can be carried out for several groups of the first battery compartments and the second battery compartments in a stacked state, avoiding heat accumulation in the battery compartments. The ejecting member is composed of an electric push rod and a top block in combination. By driving the top block through the electric push rod, the fully charged battery box can be pushed out by using the top block.

[0014] As a further technical solution of the present invention, a first plug is fixedly installed in the middle position on the outer surface of one end of the two-way joint, and a second plug is fixedly installed in the middle position on the outer surface of the other end of the two-way joint. The ends of the first plug and the second plug are both arc-shaped structures. Two groups of magnetic stickers are provided on the outer surface of the two-way joint. When the first battery compartment and the second battery compartment are spliced horizontally, the two-way joint can be used to connect the ends of the first battery compartment and the second battery compartment in series. Place the two-way joint between the first battery compartment and the second battery compartment, so that the first plug and the second plug are respectively inserted into the corresponding docking card slots, and then use the magnetic stickers to reinforce the two-way joint to complete the horizontal series connection of the first battery compartment and the second battery compartment.

[0015] As a further technical solution of the present invention, a charging end is provided at the upper end of the limit plug. Two fixed clamping heads are provided on the outer surface of one end of the charging base. Splicing grooves are provided on the inner sides of both ends of the charging base. A guide plate is movably installed in the middle of the other end of the charging base. A guide groove for cooperating with the guide plate is provided at one end of the charging base.

The single battery block is light in weight and convenient to carry.

[0017] As a further technical solution of the present invention, a second power connection terminal is fixedly installed at the middle position of the outer surface of the lower end of the lifting plug-in. Lifting sliding buckles are arranged on both sides of the lifting plug-in. By using the second power connection terminal, after the battery box and several groups of battery blocks are spliced, by pressing down the lifting plug-in, the lifting plug-in can drive the second power connection terminal to move downward, and insert the second power connection terminal into the charging slot of the battery box, which is convenient for inserting and removing several groups of battery blocks for storage.

[0018] As a further technical solution of the present invention, lead screws are arranged at both ends of the lifting frame. A motor and a chain are arranged at the upper end of the lead screw. A push plate is arranged at the upper end of the power-taking sliding plate, and electric casters are arranged at the bottom of the power-taking sliding plate. The motor uses the chain to synchronously drive the two lead screws to rotate, so that the lead screws drive the lifting frame to move up and down, move the lifting frame to the corresponding height, and use the electric casters to drive the power-taking sliding plate to translate, so that the power-taking sliding plate moves to the first battery compartment and the second battery compartment.

[0019] As a further technical solution of the present invention, fixed top covers are installed at the upper ends of the first battery compartment and the second battery compartment at the top, and casters are arranged at the lower part of the charging base.

[0020] The beneficial effects of the present invention:

[0021] 1. By setting the two-way joint and the splicing frame, when the multi-purpose household standby battery energy storage cabinet is used, by using the two-way joint in cooperation with the splicing frame, the first battery compartment and the second battery compartment can be assembled in a stacked manner or horizontally spliced, so that the height and width of the battery energy storage cabinet can be adjusted arbitrarily, making it better suitable for household use scenarios and improving its flexibility during use. When performing the stacked assembly operation, the user first places the first battery compartment or the second battery compartment at the upper part of the charging base. After the charging base is powered on, it charges the entire battery energy storage cabinet. The user installs the first battery compartment or the second battery compartment from top to bottom in turn, so that the splicing frame below is inserted into the card slot above to complete the stacking operation of the first battery compartment and the second battery compartment. The electric connection joints are used to connect several groups of the first battery compartments or the second battery compartments in series in a stacked manner. Secondly, when assembling side by side, it is necessary to use the two-way joint in cooperation. The two-way joint can be used to assemble the first battery compartment and the second battery compartment side by side, so that the first battery compartment is fixed on one side of the second battery compartment. The two-way joint is placed between the first battery compartment and the second battery compartment, so that the first plug and the second plug are respectively inserted into the corresponding docking card slots, and the two-way joint is reinforced by using the magnetic sticker to complete the horizontal series connection of the first battery compartment and the second battery compartment. At the same time, the assembled first battery compartment and the second battery compartment are connected in series and powered on, so that the multi-purpose household standby battery energy storage cabinet has a two-way splicing structure, enabling it to be adjusted arbitrarily according to the size of the household space and improving its flexibility during use.

[0022] 2. By setting up a lifting frame and a power-taking slide plate, to solve the problem of inconvenient access to the battery boxes at high positions during the combined operation of the multi-purpose household backup battery energy storage cabinet, when the stacked installation reaches a certain height, it is possible to choose to install a lifting frame and a power-taking slide plate, so that the battery energy storage cabinet has an automatic access function. During operation, the motor uses a chain to synchronously drive the rotation of two lead screws, causing the lead screws to drive the lifting frame to move up and down. Move the lifting frame to the corresponding height, and use the electric casters to drive the power-taking slide plate to translate, so that the power-taking slide plate moves to the first battery compartment and the second battery compartment. In both the first battery compartment and the second battery compartment, there are ejection parts installed. The ejection parts are composed of an electric push rod and a top block. By driving the top block with the electric push rod, the fully charged battery box can be pushed out by the top block, so that the battery box is placed on the power-taking slide plate, and then the fully charged battery box is removed by the movement of the lifting frame. Secondly, when installing the battery box, place the battery box on the power-taking slide plate, and use the movement of the power-taking slide plate and the lifting frame to move the battery box to the corresponding position of the first battery compartment or the second battery compartment, and then use the electric push rod to drive the push plate, so that the push plate pushes the battery box to move, and the battery box is inserted into the first battery compartment or the second battery compartment for charging operation.

[0023] 3. By setting up a lifting plug-in, when the multi-purpose household backup battery energy storage cabinet is in use, the battery blocks can be flexibly plugged and unplugged by using the lifting plug-in, thus effectively improving the use of the battery energy storage cabinet, enabling the user to select the corresponding size of the battery block according to needs. During operation, by using the second power connection end, after the battery box and several groups of battery blocks are spliced, by pressing down the lifting plug-in, the lifting plug-in drives the second power connection end to move down, and the second power connection end is inserted into the charging slot of the battery box, which is convenient for plugging and unplugging and accessing several groups of battery blocks. There are multiple battery blocks of different sizes installed in the battery box, which is convenient for its flexible use. Secondly, when the first battery compartment and the second battery compartment are spliced horizontally, by using the splicing groove to dock the fixed card head, the charging seats of the first battery compartment and the second battery compartment can be spliced and fixed. At the same time, to avoid the misalignment of multiple double-headed connectors during docking, by using the guide plate to dock the two groups of charging seats along the guide groove, the accuracy of the horizontal splicing of the first battery compartment and the second battery compartment can be effectively improved, and the misalignment of the double-headed connectors can be avoided.
