[0021] Example, see Figures 1 to 6 A modular battery box for an intelligent mobile charging and storage vehicle comprises an energy storage compartment 1, an extended inner compartment 2 and a plurality of module batteries arranged in the extended inner compartment 2. The energy storage compartment 1 is provided with an electric push control device for controlling the telescopic movement of the extended inner compartment 2. The sliding connection between the extended inner compartment 2 and the energy storage compartment 1 is a conventional technical means and is not described in detail herein. Furthermore, the electric push control device comprises two electric push rods 9 arranged in the energy storage compartment 1. The electric push rods 9 are prior art and are not described herein. A wiring slide 10 is connected to the output end of the electric push rod 9, and a fixed cover 11 is arranged above the extended inner compartment 2. The wiring slide 10 is slidably arranged in the fixed cover 11, and the end is connected to the fixed cover 11 through a resisting spring 12.

[0022] The energy storage compartment 1 is connected to the extended inner compartment 2 through a magnetic adsorption component; further, the magnetic adsorption component includes an electromagnetic frame 16 arranged on the inner side wall of the energy storage compartment 1, and a fixed magnetic frame 17 magnetically attracted to the electromagnetic frame 16 is arranged on the side wall of the extended inner compartment 2. The resistance generated by the magnetic attraction can ensure that the extended inner compartment 2 has sufficient resistance when moving outward, and the resistance is much greater than the friction between the L-shaped wiring member 15 and the side wiring port 13, that is, when the extended inner compartment 2 moves outward, the effect of the resistance will cause the wiring slide 10 and the fixed cover 11 to slide and displace, and the displacement will cause the L-shaped wiring member 15 that was originally in a connected state to be separated from the side wiring port 13, thereby achieving the effect of automatic power-off, thereby protecting the user.

[0023] The module battery includes a box-type battery housing 3 and a battery pack arranged in the box-type battery housing 3. Both sides of the box-type battery housing 3 are densely provided with heat dissipation openings. A wiring slot is provided above the box-type battery housing 3. A power supply interface 4 for an external charging circuit is provided in the wiring slot. A movable protective device is provided above the wiring slot. The movable protective device includes a sliding connection port 18 provided on both sides of the box-type battery housing 3. A rectangular docking port is provided on the side wall of the sliding connection port 18. A rectangular block 19 is slidably provided on the inner wall of the rectangular docking port. The rectangular block 19 is connected to the inner wall of the rectangular docking port through a resisting spring 12. The rectangular block 19 is connected to a cover plate 20 through a rotating shaft. It should be noted that the cover plate 20 is rotatably connected to the rotating shaft, and a torsion spring is arranged between the two, which can make the cover plate 20 have a certain downward pressure on the middle wiring slot without being affected by external force. Therefore, under the action of the two cover plates 20, the daily closure of the wiring slot can be achieved to ensure the protection effect. When the module battery enters the storage cavity, the inner wall of the storage cavity will generate pressure on one end face of the cover plate 20 thereon. Under the action of pressure, the cover plate 20 will automatically flip from a horizontal state to a vertical state, thereby achieving the effect of automatically opening the wiring slot.

[0024] The wiring slot is connected to the electric push control device through an automatic charging and discharging device; further, the automatic charging and discharging device includes two side wiring ports 13 opened in the wiring slot, a wiring board 14 is arranged at the bottom of the wiring slide 10, and an L-shaped wiring member 15 adapted to the side wiring port 13 is arranged at the bottom of the wiring board 14. The wiring boards 14 on both sides are respectively a charging board and a feedback board, which can realize charging and energy storage of the module battery through the charging board during the valley of electricity consumption, and feed back the electric energy of the module battery to the power grid through the feedback board during the peak of electricity consumption, thereby meeting the demand for regulating energy storage.

[0025] A plurality of storage chambers adapted to the module batteries are provided in the extended inner compartment 2. The bottom of the storage chamber is through-set for the module batteries to move downward for loading. A heating device 5 is provided on the inner wall of the storage chamber. The heating device 5 is a heating structure, which is a prior art and will not be described in detail here. The two sides of the extended inner compartment 2 are connected with a load-bearing vertical plate 6 through a lifting and loading device. Furthermore, the lifting and loading device includes an adjustment motor 21 provided in the extended inner compartment 2. When it is necessary to control the taking of each module battery individually, each group of module batteries can be provided with an adjustment motor 21. For control, the structure of the lifting loading device required for its transmission is consistent, the output end of the adjusting motor 21 is connected to the driving worm shaft 22, transmission covers are provided on both sides of the extended inner compartment 2, and a lifting gear 23 is provided inside the transmission cover. The lifting gear 23 is connected to the transmission worm wheel through a rotating shaft, and the transmission worm wheel is meshed with the driving worm shaft 22. A limited vertical groove 24 is provided on the side wall of the extended inner compartment 2, and a rectangular limit block 25 adapted to the limited vertical groove 24 is provided on the inner wall of the bearing vertical plate 6, and a straight tooth groove 26 meshed with the lifting gear 23 is provided on the side walls of the bearing vertical plate 6.

[0026] The adjacent supporting vertical plate 6 is connected with a loading seat 7, and the loading seat 7 is connected with the box-type battery housing 3 through a positioning trapezoidal member 8. The positioning trapezoidal member 8 is fixedly arranged on the upper surface of the loading seat 7, and a corresponding positioning opening adapted to the positioning trapezoidal member 8 is provided at the bottom of the box-type battery housing 3. The trapezoidal positioning trapezoidal member 8 can ensure the positioning effect of the box-type battery housing 3 on the loading seat 7, and ensure that the module battery can be safely placed in the compartment.

[0027] The energy storage charging vehicle proposed in the present invention has two modes when charging, including a centralized charging mode and a decentralized heat dissipation charging mode. According to the temperature requirements of battery charging and discharging, when the outdoor temperature is low, the centralized charging mode is performed. In order to ensure the high efficiency of the energy storage battery, the heating device 5 arranged on one side of the storage cavity can be turned on. The module battery in the storage cavity is kept warm by the heating device 5. At this time, the module battery in the energy storage charging vehicle can be charged through the power grid to realize energy storage. At this time, the module battery in the relatively sealed extended inner compartment 2 can ensure a good use environment, thereby ensuring that the module battery can store energy efficiently to the greatest extent; When the outdoor temperature is high, a large amount of heat will be generated during centralized charging. For large-capacity energy storage batteries, high heat will pose a greater risk, so a decentralized heat dissipation charging mode is adopted. At this time, the electromagnetic frame 16 is powered to generate magnetism. Under the action of magnetic resistance, the extended inner compartment 2 will move outward and generate resistance. The electric push rod 9 will drive the wiring slide 10 to move, thereby squeezing the resistance spring 12, so that a relative displacement is generated between the wiring slide 10 and the extended inner compartment 2. Under this action, the L-shaped wiring member 15 originally inserted into the side wiring port 13 will be disengaged, realizing the charging disconnection between the two. At this time, the module battery after the wiring is released is driven downward by the lifting loading device, and the module battery is charged one by one through the external charging line. The module batteries on the outside have heat dissipation channels between each other, which can meet the charging and discharging requirements in hot weather; When it is necessary to supply power through a mobile energy storage charging vehicle, when the charging vehicle is required to be charged on the move, according to the number of vehicles that need to be charged, it can be selected whether to supply power to multiple module batteries separately. When supplying power in a centralized manner, power can be supplied through a charging port pre-set on the mobile energy storage charging vehicle. When supplying power separately through multiple module batteries, the driving worm shaft 22 is driven to rotate by adjusting the motor 21, and the lifting gear 23 is driven to rotate, so that the bearing vertical plate 6 meshing with it moves downward, and the module battery is moved downward from the bottom of the extended inner compartment 2. The module battery moved to the bottom can be freely taken, and the module battery is distributed to meet the charging needs of multiple vehicles; After use, when charging is required, the module battery is placed on the loading seat 7, and the load-bearing vertical plate 6 is driven upward by the lifting loading device to transport the module battery upward into the extended inner compartment 2. During this process, the inner wall of the storage cavity will generate pressure on one end surface of the cover plate 20 thereon. Under the action of the pressure, the cover plate 20 will automatically flip from a horizontal state to a vertical state, so that the wiring slot is automatically opened. At this time, the side wiring port 13 above the module battery that continues to move upward will correspond to the L-shaped wiring member 15, controlling the electric push rod 9 to move. When the electric push rod 9 moves horizontally, it will The wiring slide 10 moves horizontally, and the extended inner compartment 2 connected to the wiring slide 10 by the resistance spring 12 moves horizontally into the energy storage compartment 1. When the extended inner compartment 2 is completely moved into the energy storage compartment 1, the extended inner compartment 2 cannot move. At this time, the electric push rod 9 drives the wiring slide 10 to move, which will automatically dock the L-shaped wiring member 15 with the side wiring port 13, thereby realizing the docking of charging and discharging signals of multiple module batteries with the energy storage compartment 1, so as to meet the functions of charging and discharging together as a whole, achieve the requirements of centralized use, and meet the use needs of the energy storage charging vehicle under various usage conditions.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
