[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "top / bottom end", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0029] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "provided with", "sheathed / connected", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Example, refer to Figures 1 to 6 A modular battery box for an intelligent mobile charging and storage vehicle, comprising a storage compartment 1, an extended inner compartment 2, and a plurality of modular batteries arranged in the extended inner compartment 2. An electric push control device for controlling the telescopic movement of the extended inner compartment 2 is arranged in the storage compartment 1. The sliding connection mode between the extended inner compartment 2 and the storage compartment 1 is a conventional technical means and will not be elaborated in detail here. Further, the electric push control device includes two electric push rods 9 arranged in the storage compartment 1. The electric push rod 9 is a prior art and will not be elaborated here. The output end of the electric push rod 9 is connected to a wiring sliding seat 10. A fixed cover 11 is arranged above the extended inner compartment 2. The wiring sliding seat 10 is slidably arranged in the fixed cover 11 and is connected to the fixed cover 11 through a contact spring 12 at the end.

[0031] The energy storage compartment 1 is connected to the extended inner compartment 2 through magnetic suction accessories; further, the magnetic suction accessories include an electromagnetic frame 16 provided on the inner side wall of the energy storage compartment 1, and a fixed magnetic frame 17 that is magnetically attracted to the electromagnetic frame 16 is provided on the side wall of the extended inner compartment 2. The resistance generated by the magnetic suction force can ensure that when the extended inner compartment 2 moves outward, there is sufficient resistance, and the resistance is much greater than the friction force between the L-shaped wiring part 15 and the side wiring port 13. That is, when the extended inner compartment 2 moves outward, the resistance will cause the wiring slide seat 10 and the fixed cover 11 to generate a sliding displacement, and the generation of the displacement will cause the originally connected L-shaped wiring part 15 and the side wiring port 13 to be separated, achieving the effect of automatic power-off, thereby protecting the user.

[0032] The modular battery includes a box-type battery housing 3 and a battery pack provided in the box-type battery housing 3. Heat dissipation vents are densely arranged on both sides of the box-type battery housing 3. A wiring groove is opened above the box-type battery housing 3. A power supply interface 4 for an external charging line is provided in the wiring groove. A movable protection device is provided above the wiring groove. The movable protection device includes sliding connection ports 18 opened on both sides of the box-type battery housing 3. A rectangular docking port is opened on the side wall of the sliding connection port 18. A rectangular block 19 is slidably arranged 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 contact spring 12. The rectangular block 19 is connected to a cover plate 20 through a rotating shaft;

[0033] It should be noted that the cover plate 20 is rotatably connected to the rotating shaft, and a torsion spring is provided between the two, which can make the cover plate 20 have a certain downward pressure on the middle wiring groove without external force. Therefore, under the action of the two cover plates 20, the daily closing of the wiring groove can be realized to ensure the protection effect. When the modular battery enters the storage cavity, the inner wall of the storage cavity will generate pressure on one end face of the cover plate 20 on it. Under the action of the pressure, the cover plate 20 will automatically flip from the horizontal state to the vertical state, realizing the effect of automatically opening the wiring groove.

[0034] The wiring groove is connected to the electric push control device through an automatic charge and discharge device; further, the automatic charge and discharge device includes two side wiring ports 13 opened in the wiring groove. A wiring board 14 is provided at the bottom of the wiring slide seat 10. An L-shaped wiring part 15 adapted to the side wiring port 13 is provided at the bottom of the wiring board 14. The two wiring boards 14 on both sides are respectively a charging board and a feedback power board, which can realize charging and energy storage of the modular battery through the charging board during the valley value of power consumption, and feedback the electric energy of the modular battery to the power grid through the feedback power board during the peak value of power consumption, so as to meet the demand for regulating energy storage.

[0035] A plurality of storage cavities adapted to the modular batteries are provided in the extended inner box body 2. The bottom of the storage cavity is provided with a through hole for the modular battery to move downward for loading. A heating device 5 is arranged on the inner side wall of the storage cavity. The heating device 5 is a heating structure, which is a prior art and will not be elaborated here. Both sides of the extended inner box body 2 are connected with a load-bearing vertical plate 6 through a lifting loading device. Further, the lifting loading device includes an adjusting motor 21 arranged in the extended inner box body 2. When it is necessary to individually control the taking of each modular battery, each group of modular batteries can be provided with an adjusting motor 21 for control. The structures of the lifting loading devices required for their transmission are the same. The output end of the adjusting motor 21 is connected with a driving worm shaft 22. Transmission covers are arranged on both sides of the extended inner box body 2. A lifting gear 23 is arranged inside the transmission cover. The lifting gear 23 is connected with a transmission worm gear through a rotating shaft. The transmission worm gear is meshed and connected with the driving worm shaft 22. A limiting vertical groove 24 is opened on the side wall of the extended inner box body 2. A rectangular limiting block 25 adapted to the limiting vertical groove 24 is arranged on the inner side wall of the load-bearing vertical plate 6. Straight tooth grooves 26 meshed with the lifting gear 23 are arranged on both side walls of the load-bearing vertical plate 6.

[0036] Adjacent load-bearing vertical plates 6 are connected with a loading seat 7. The loading seat 7 is combined and 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. A corresponding positioning port adapted to the positioning trapezoidal member 8 is opened at the inner bottom of the box-type battery housing 3. The trapezoidally arranged positioning trapezoidal member 8 can ensure the positioning effect of the box-type battery housing 3 on the loading seat 7 and ensure the safe entry of the modular battery into the box.

[0037] When the energy storage charging vehicle proposed by the present invention is charging, it has two modes, including a centralized charging mode and a decentralized heat dissipation charging mode. According to the temperature requirements of the charging and discharging of the battery, when the outdoor temperature is relatively low, the centralized charging mode is carried out. In order to ensure the high-efficiency operation of the energy storage battery, the heating device 5 arranged on one side of the storage cavity can be turned on. The heating device 5 heats the modular battery in the storage cavity to keep it warm. At this time, the modular battery in the energy storage charging vehicle can be charged through the power grid to realize energy storage. At this time, the modular battery in the relatively sealed extended inner box body 2 can ensure a good use environment, so as to ensure that the modular battery can store energy efficiently to the greatest extent;

[0038] When the outdoor temperature is relatively high, a large amount of heat will be generated during centralized charging. For large-capacity energy storage batteries, high heat poses a significant risk. Therefore, 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, when the extended inner box body 2 moves outward, resistance will be generated. The electric push rod 9 will drive the wiring slide seat 10 to move, thereby squeezing the contact spring 12, causing a relative displacement between the wiring slide seat 10 and the extended inner box body 2. Under this action, the L-shaped wiring part 15 originally inserted into the side wiring port 13 will be disengaged, realizing the disconnection of charging between the two. At this time, the loading device is lifted to drive the module battery after disconnection of the wiring to move downward, and the module battery is charged one by one through an external charging cable. The module batteries on the outside have heat dissipation channels between them, which can meet the charging and discharging requirements in hot weather;

[0039] When it is necessary to supply power through a mobile energy storage charging vehicle, when the charging vehicle needs to move for charging, according to the number of vehicles that need to be replenished with electricity, it can be selected whether to supply power separately to multiple module batteries. During centralized power supply, 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 regulating motor 21 is driven to drive the driving worm shaft 22 to rotate, driving the lifting gear 23 to rotate, so that the bearing vertical plate 6 engaged and connected with it moves downward, and the module battery is moved downward from the bottom of the extended inner box body 2. The module battery moved to the lower part can be freely taken, and the module battery is used for decentralized power supply to meet the charging needs of multiple vehicles;

[0040] After use, when centralized charging is required, the module battery is placed on the loading seat 7, and the bearing vertical plate 6 is driven to move upward by the lifting loading device, and the module battery is conveyed upward into the extended inner box body 2. During this process, the inner wall of the storage cavity will exert pressure on one end face of the cover plate 20 located thereon. Under the action of the pressure, the cover plate 20 will automatically flip from the horizontal state to the vertical state, causing the wiring groove to be automatically opened. At this time, the side wiring port 13 above the continuously moving upward module battery will correspond to the L-shaped wiring part 15, and the electric push rod 9 is controlled to move. When the electric push rod 9 moves horizontally, the wiring slide seat 10 will move horizontally. The extended inner box body 2 connected to the wiring slide seat 10 through the contact spring 12 will move horizontally into the energy storage carriage 1. When the extended inner box body 2 completely moves into the energy storage carriage 1 and the extended inner box body 2 cannot move, at this time, the electric push rod 9 drives the wiring slide seat 10 to move, which will cause the L-shaped wiring part 15 to be automatically docked with the side wiring port 13, thereby realizing the docking of the charging and discharging signals of multiple module batteries with the energy storage carriage 1, so as to meet the functions of charging and discharging together as a whole, achieving the requirements of centralized use and meeting the use requirements of the energy storage charging vehicle under various use conditions.

[0041] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
