[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 The present invention provides the following technical solution: a modularly spliced ​​energy storage power integrated box, including at least two boxes 1 spliced ​​end to end in the horizontal or vertical direction, and further including: a first locking mechanism 4 and a positioning mechanism 5.

[0022] Furthermore, by Figure 1 As shown in this embodiment, two sets of first locking mechanisms 4 are symmetrically arranged between two adjacent boxes 1 to achieve detachable fixing of the two adjacent boxes 1. Four sets of positioning mechanisms 5 are arranged diagonally between two adjacent boxes 1 to achieve positioning when the two adjacent boxes 1 are spliced. After adopting the above scheme, in actual use, it is necessary to first determine the number of boxes 1 and the splicing direction (horizontal or vertical) according to the energy storage capacity requirements and installation space conditions.

[0023] During assembly, precise alignment is achieved first by relying on four sets of diagonally arranged positioning mechanisms 5. Through the double constraint of the diagonal points, the offset of adjacent boxes 1 in the horizontal, vertical and longitudinal directions is effectively limited, ensuring that the splicing surfaces of the two boxes 1 are completely fitted, and that key components such as electrical interfaces and heat dissipation channels on the boxes 1 are precisely aligned, laying the foundation for subsequent locking and functional connection.

[0024] After positioning, the two sets of symmetrically arranged first locking mechanisms 4 realize the detachable fixing of adjacent boxes 1. The two sets of symmetrically arranged designs can make the locking force evenly distributed on both sides of the splicing surface, avoiding deformation of box 1 or loosening of splicing due to force on one side, ensuring the stability of the overall structure, and meeting the needs of subsequent disassembly and maintenance.

[0025] Furthermore, the integrated box system after splicing also features flexible expansion and convenient maintenance: when it is necessary to increase the energy storage capacity, box 1 can be added along the original splicing direction, repeating the process of "aligning the positioning mechanism 5 - fixing the first locking mechanism 4 - connecting the electrical terminals", without the need for major modifications to the existing system; if a single box 1 malfunctions (such as damage to the energy storage unit or abnormal heat dissipation), it is only necessary to release the first locking mechanism 4 on both sides of the corresponding box 1 to separate the faulty box 1 from the other box 1, replace it with a new box 1 or repair the faulty box 1 and re-splice it. The whole process does not require stopping the machine to disassemble the entire system, only affecting the faulty box 1, which greatly reduces maintenance costs and downtime.

[0026] Optionally, by Figure 1 and Figure 3 As shown, in this embodiment, the first locking mechanism 4 includes a first flip screw 41, a first limiting plate 42, a first wing nut 43, a first mounting lug with a hole 44, and a first pin 45; the first flip screw 41 is hinged to the top of the outer side wall of the housing 1; the first limiting plate 42 is fixed to the bottom of the outer side of the housing 1, and a first notch 421 is provided on the first limiting plate 42, through which the first flip screw 41 passes when flipped to the vertical state; the first wing nut 43 is provided at the protruding end of the first flip screw 41 by thread engagement; the first mounting lug with a hole 44 is fixed to the outer side wall of the housing 1; the first pin 45 is fixed to the first flip screw 41. 1. The outer wall, and the first pin 45 passes through the first mounting ear with hole 44 to form a rotating structure. After adopting the above scheme, when using and splicing, the first flip screw 41 in the initial state is in the retracted state. At this time, the first pin 45 passes through the first mounting ear with hole 44 to provide a rotation fulcrum for the first flip screw 41. The operator manually flips the first flip screw 41 upward to make it rotate around the first pin 45 to the vertical state. At this time, the first flip screw 41 just passes through the first notch 421 of the first limiting plate 42 on the adjacent box 1. The first notch 421 limits the first flip screw 41 to prevent it from shifting left and right during the subsequent locking process.

[0027] Afterwards, the operator tightens the first wing nut 43 on the extended end of the first flip screw 41. Since the first wing nut 43 and the first flip screw 41 are screwed together, as the first wing nut 43 is tightened, its bottom gradually presses against the upper surface of the first limiting plate 42. The thread preload force tightly presses the splicing surfaces of the two adjacent boxes 1 together. After the two sets of symmetrically arranged first locking mechanisms 4 operate synchronously, their locking force acts on both ends of the box 1 respectively, so that the locking force is evenly distributed on both sides of the splicing surface, avoiding deformation of the box 1 or loosening of the splicing due to force on one side.

[0028] When it is necessary to disassemble the housing 1, loosen the first wing nut 43 in the reverse direction until it is disengaged from the extended end of the first flip screw 41, and then flip the first wing nut 43 downward around the first pin 45 to disengage from the first notch 421. This will release the mechanical lock between the two housings 1, and complete the disassembly of the housing 1 in conjunction with the separation operation of the positioning mechanism 5.

[0029] Optionally, by Figure 1 and Figure 4 As shown, in this embodiment, the positioning mechanism 5 includes a fixing block 51, a positioning post 52, and a positioning block 53; the fixing block 51 is fixed to the top of the outer side of the box 1; the positioning post 52 is fixed to the top surface of the fixing block 51; the positioning block 53 is fixed to the bottom of the outer side of the box 1, and a positioning hole 531 for the positioning post 52 to pass through is provided on the positioning block 53. After adopting the above scheme, when the box 1 is spliced, one box 1 is brought close to another box 1, and the positioning hole 531 is used to position the splicing of the two box 1.

[0030] After the two boxes 1 are docked, the positioning pin 52 passes through the positioning hole 531, restricting the relative displacement of the adjacent boxes 1 in the horizontal direction, and providing a stable basis for subsequent locking operations.

[0031] Optionally, by Figure 1 As shown in this embodiment, three boxes 1 are spliced ​​together longitudinally to form an integrated energy storage power supply box. The three boxes 1 include an energy storage box 11, a control box 12, and a heat dissipation box 13 from bottom to top. With the above scheme, when in use, the energy storage box 11 is located at the bottom layer and contains energy storage units such as lithium battery packs; the control box 12 contains an energy storage controller, a charge and discharge management module, and a communication module; and the heat dissipation box 13 is spliced ​​on the top of the control box 12.

[0032] Optionally, by Figure 1 and Figure 5As shown, this embodiment also includes a flip cover 2, a cooling fan 3, and a second locking mechanism 6; the flip cover 2 is hinged to the top opening of the heat sink 13, the cooling fan 3 is fixed to the bottom surface of the flip cover 2, and heat dissipation louvers 14 are provided on the energy storage box 11, the control box 12, and the heat sink 13; after the flip cover 2 is closed, it is locked to the heat sink 13 by the second locking mechanism 6, wherein the second locking mechanism 6 includes a second flip screw 61, a second limiting plate 62, a second wing nut 63, a second mounting lug with a hole 64, and a second pin 65; the second flip screw 61 is hinged to the top of the outer wall of the heat sink 13; the second limiting plate 62 is fixed to the flip cover 2 from the top opening of the heat sink 13. The second notch 621 is provided on the second limiting plate 62, and the second flip screw 61 passes through the second notch 621 when it is flipped to the vertical state; the second wing nut 63 is provided on the extended end of the second flip screw 61 by means of thread engagement; the second mounting ear with hole 64 is fixed to the outer wall of the heat sink 13; the second pin 65 is fixed to the outer wall of the second flip screw 61, and the second pin 65 passes through the second mounting ear with hole 64 to form a rotating structure. After adopting the above scheme, when the integrated box is running normally, the flip cover 2 is in the closed state, and the control box 12 starts the cooling fan 3 according to the detected temperature signal (the control box 12 has a built-in temperature sensor).

[0033] Cooling fan 3 blows cold air downwards, and the cold air flows through control box 12 and energy storage box 11 in sequence, and finally exits from heat dissipation louvers 14, carrying away the heat of controller and battery.

[0034] In the initial state, the second flip screw 61 is in the retracted state (fitting against the outer wall of the heat sink 13). The operator flips the second flip screw 61 upwards to rotate it to a vertical state. At this time, the second flip screw 61 just passes through the second notch 621 on the second limiting plate 62 at the free end of the flip cover 2. The second wing nut 63 is tightened so that its bottom presses against the upper surface of the second limiting plate 62. The preload of the thread tightly presses the flip cover 2 against the top of the heat sink 13, preventing the flip cover 2 from loosening due to vibration of the cooling fan 3 or external impact during operation, and ensuring the stability of the airflow channel.

[0035] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, both the energy storage box 11 and the control box 12 are equipped with wiring boards 7, and wiring holes 71 are opened on the wiring boards 7. With the above solution, when in use, the power cable passes through the wiring holes 71 and is directly connected to the power output terminal (copper busbar interface) in the energy storage box 11, without the need for long wiring or cross-twisting.

[0036] Preferably, by Figure 1 and Figure 2As shown in this embodiment, handles 15 are fixed on both opposite outer walls of the energy storage box 11, control box 12, and heat dissipation box 13. With the above solution, the handles 15 serve as the "operational auxiliary core components" of the box 1 (energy storage box 11, control box 12, and heat dissipation box 13) during use. Through the symmetrical fixing design of the two opposite outer walls, a stable force point is provided for the handling, longitudinal splicing and alignment, and maintenance and disassembly of the box 1, while avoiding damage to the structure and internal components of the box 1 during operation.

[0037] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0038] Components not described in detail in this article are existing technologies.

[0039] The working principle and usage process of this utility model: When using the modular splicing energy storage power integrated box of this utility model, the installation follows the logic of "from bottom to top, first positioning and then locking, and synchronous electrical connection". The handle 15 assists in operation, the positioning mechanism 5 ensures accuracy, the first locking mechanism 4 achieves rigid fixation, and the wiring board 7 ensures that the cables are neat.

[0040] Operators use the handles 15 on both sides of the energy storage box 11 to move it to the horizontal installation surface by two people applying symmetrical force (if the weight is large, hoisting straps can be attached to the handles 15 to assist in hoisting), ensuring that the box 1 is placed stably. The energy storage box 11 has a built-in lithium battery pack and BMS sensor. The internal wiring board 7 has completed the pre-organization of the cables. The high-power cables of the battery series and parallel are passed through the wiring hole 71 and connected to the power output terminal at the top of the box 1. The BMS temperature / voltage signal line is passed through the wiring hole 71 and connected to the top signal terminal. The cable length is preset according to the "interconnection control box 12" and there is no redundancy. Two people hold the handles 15 on both sides of the control box 12 and hoist it to the top of the energy storage box 11. If there is a slight deviation, apply a lateral fine adjustment force through the handles 15 to align the positioning block 53 at the bottom of the control box 12 with the fixing block 51 and positioning post 52 at the top of the energy storage box 11. Slowly lower the control box 12, and the positioning post 52 passes through the positioning hole 531 of the positioning block 53, so that the splicing surfaces of the two boxes 1 are completely fitted together; at this time, the electrical terminals (power input, BMS signal input) at the bottom of the control box 12 are connected to the top terminals of the energy storage box 11 through the pre-guided cables of the wiring board 7. The first retractable screw 41 is flipped around the first pin 45 to a vertical position, so that it passes through the first notch 421 of the first limiting plate 42 at the bottom of the control box 12; the first wing nut 43 is tightened, and the two boxes 1 are pressed together by the thread preload, and the symmetrical locking force counteracts the gravity of the control box 12 to prevent longitudinal loosening. The wiring board 7 inside the control box 12 is divided into "input-control-output" sections: the holes in the input section guide the cables to connect to the energy storage box 11, the holes in the control section connect the controller to the charging / discharging / communication module, and the holes in the output section are reserved for heat dissipation control cables (connecting to the heat dissipation box 13) and external charging / discharging interface cables. All cables are run through the corresponding wiring holes 71. Repeat the assembly process of control box 12: Move heat sink 13 to the top of control box 12 using handle 15. Positioning post 52 of positioning mechanism 5 and positioning hole 531 are precisely matched so that the heat dissipation signal terminal (fan power supply, temperature feedback) at the bottom of heat sink 13 is connected to the terminal at the top of control box 12. Operate the first locking mechanism 4 at the top of control box 12 (same as above) to fix heat sink 13. Flip the hinged flip cover 2 at the top of the heat sink 13 downwards to cover the opening of the box 1; at this time, the cooling fan 3 on the bottom of the flip cover 2 faces the inside of the heat sink 13, forming a directional airflow channel. Operate the second locking mechanism 6: rotate the second flip screw 61 at the top of the outer wall of the heat sink 13 around the second pin 65 to a vertical position, and pass through the second notch 621 of the second limiting plate 62 at the free end of the flip cover 2; tighten the second wing nut 63 to make the flip cover 2 tightly pressed together.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
