Technical Field
[0001] This utility model relates to the technical field of mobile energy storage systems, and specifically to a main control module connection device for a split-type mobile energy storage system. Background Technology
[0002] The main control module of the split mobile energy storage system is equivalent to the "brain" of the entire system. The main control module is connected to the battery module by a power cable, providing a power channel for charging and discharging the battery module. The cable specifications must be selected according to the rated current of the system to ensure safe transmission of electrical energy. At the same time, a signal cable is used to connect the main control module to other components.
[0003] Currently, the device exhibits two pressing issues during actual operation: Firstly, the device integrates multiple batteries and a main control module, which generates significant heat during continuous operation. This heat accumulates within the relatively enclosed equipment, hindering effective dissipation and severely impacting the stability of the main control module's operation. This could lead to decreased control accuracy, slow response, or even malfunctions. Secondly, the connection and disconnection of the main control module and cables currently relies on manual pulling. This method is not only cumbersome and inefficient, but also prone to causing cable joints to loosen or become damaged due to uneven force or cable entanglement during pulling. This increases the risk of electric shock and short circuits, severely affecting the safety of the disassembly and disconnection process. Summary of the Invention
[0004] The purpose of this invention is to provide a main control module connection device for a split-type mobile energy storage system, so as to solve the above-mentioned defects caused by the prior art.
[0005] A main control module connection device for a split-type mobile energy storage system includes an energy storage box, a bottom sealing plate, a battery controller, and cable terminals. A door is hinged to one side of the energy storage box. Multiple sets of power connection holes are evenly spaced at the bottom of the energy storage box. A cooling mechanism is installed on the outside of the energy storage box, which discharges hot air from inside the energy storage box through an exhaust box at the top and simultaneously purifies and filters the intake air using an air intake box on one side of the door. A docking mechanism is installed on one side of the energy storage box, with a carefully designed bottom sealing plate at its bottom. This bottom sealing plate fits tightly with the docking box. Multiple sets of cable terminals are installed at the top of the bottom sealing plate, and these cable terminals accurately engage with the battery controller. Multiple lithium battery packs are installed inside the energy storage box.
[0006] Furthermore, the cooling mechanism includes an air inlet box, an air filter element, an exhaust box, a servo fan, a fin assembly, and exhaust vents. The exhaust box is located directly above the energy storage box, and exhaust vents are evenly spaced at the bottom of the exhaust box. The servo fan is installed inside the exhaust box. The air inlet box is installed on one side of the box door, and an air filter element is attached to one side of the air inlet box. The fin assembly is installed on one side of the docking box, and the docking box is installed on the outside of the energy storage box.
[0007] Furthermore, the air filter element has an air intake box on one side, and the air intake box is connected to the internal space of the energy storage box through a sealing interface on one side of the box door.
[0008] Furthermore, the exhaust box and the energy storage box form a closed pneumatic circuit through the mechanical coupling of the servo fan.
[0009] Furthermore, the docking mechanism includes a docking box, a bottom sealing plate, a battery controller, an electric lead screw, a slide groove, a nut slider, and cable terminals. The bottom sealing plate is provided at the bottom end of the docking box, and multiple sets of cable terminals are equally spaced above the bottom sealing plate. The slide groove is opened on one side of the docking box, and an electric lead screw is provided inside the slide groove. The battery controller is installed inside the docking box and is arranged parallel to the cable terminals. The battery controller is electrically connected to the lithium battery pack through a dedicated wiring harness.
[0010] Furthermore, the bottom sealing plate is connected to the battery controller via a snap-fit electrical connection through the cable terminals integrated on its bottom surface.
[0011] Furthermore, a guide and positioning nut slider is installed on one side of the bottom sealing plate. The slider is connected to the electric lead screw through its built-in threaded transmission mechanism to form a helical transmission connection. At the same time, the outer wall of the slider and the outer guide rail of the slide groove maintain a sliding fit.
[0012] Compared with the prior art, the present invention has the following advantages: 1. The main control module connection device of this split-type mobile energy storage system is mainly used to realize the effective connection, heat dissipation and air circulation of various components in the energy storage system, so as to ensure the stable operation of the energy storage system. The bottom sealing plate set at the bottom of the docking mechanism is tightly connected with the docking box. This docking not only realizes the physical connection, but also provides the foundation for subsequent electrical connection. The bottom sealing plate plays a role in sealing and supporting, ensuring the stability and sealing of the docking point, and preventing dust, moisture and other substances from entering the system and affecting the normal operation of the equipment.
[0013] 2. By starting, stopping, and turning the electric screw, the movement distance and final position of the bottom sealing plate can be precisely controlled to adapt to different docking requirements. While the cable terminal is docking with the battery controller, the bottom surface of the bottom sealing plate is tightly fitted with the top surface of the docking box to prevent external dust, moisture, or corrosive gases from entering the docking box and protect the battery controller and electrical connections from environmental influences.

Detailed Implementation
[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] like Figures 1 to 5As shown, a split-type mobile energy storage system main control module connection device includes an energy storage box 1, a bottom sealing plate 13, a battery controller 14, and cable terminals 19. A door 2 is hinged to one side of the energy storage box 1. Multiple sets of power connection holes 12 are evenly spaced at the bottom of the energy storage box 1. A cooling mechanism 6 is provided on the outside of the energy storage box 1. The cooling mechanism 6 discharges hot air from inside the energy storage box 1 through an exhaust box 5 at the top, and simultaneously purifies and filters the intake air using an air intake box 3 on one side of the door 2. A docking mechanism 10 is provided on one side of the energy storage box 1. The docking mechanism 10 has a carefully designed bottom sealing plate 13 at its bottom, which tightly docks with the docking box 8. Multiple sets of cable terminals 19 are provided at the top of the bottom sealing plate 13, and the cable terminals 19 accurately engage with the battery controller 14. Multiple lithium battery packs 17 are installed inside the energy storage box 1.
[0018] In this embodiment, the cooling mechanism 6 includes an air inlet box 3, an air filter element 4, an exhaust box 5, a servo fan 7, a fin assembly 9, and an exhaust vent 11. The exhaust box 5 is located directly above the energy storage box 1, and the bottom of the exhaust box 5 has exhaust vents 11 at equal intervals. The servo fan 7 is installed inside the exhaust box 5. The air inlet box 3 is installed on one side of the box door 2, and the air filter element 4 is attached to one side of the air inlet box 3. The fin assembly 9 is installed on one side of the docking box 8, and the docking box 8 is installed on the outside of the energy storage box 1. The air filter element 4 has an air inlet box 3 on one side of it. The air inlet box 3 is connected to the internal space of the energy storage box 1 through a sealing interface on one side of the box door 2. The exhaust box 5 and the energy storage box 1 form a closed pneumatic circuit through the mechanical coupling of the servo fan 7.
[0019] Among them, the servo fan 7 forms a closed pneumatic circuit with the exhaust box 5 and the energy storage box 1 through mechanical coupling. The air intake box 3 is purified by the air filter element 4. The clean air drawn in enters the interior of the energy storage box 1 and exchanges heat with the heating components such as the lithium battery pack 17. The temperature of the hot air after absorbing heat rises and is discharged through the exhaust box 5 set at the top, thus completing the air replacement and cooling.
[0020] In this embodiment, the docking mechanism 10 includes a docking housing 8, a bottom sealing plate 13, a battery controller 14, an electric lead screw 15, a slide groove 16, a nut slider 18, and cable terminals 19. The bottom sealing plate 13 is provided at the bottom end of the docking housing 8. Multiple sets of cable terminals 19 are equally spaced above the bottom sealing plate 13. The slide groove 16 is opened on one side of the docking housing 8. The electric lead screw 15 is provided inside the slide groove 16. The battery controller 14 is installed inside the docking housing 8. The battery controller 14 is arranged parallel to the cable terminals 19. The battery controller 14 is electrically connected to the lithium battery pack 17 through a dedicated wiring harness. The bottom sealing plate 13 is electrically connected to the battery controller 14 through the cable terminals 19 integrated on its bottom surface, forming a snap-fit connection. A guide and positioning nut slider 18 is installed on one side of the bottom sealing plate 13. The slider is connected to the electric lead screw 15 through its built-in threaded transmission mechanism, and the outer wall of the slider is in sliding fit with the outer guide rail of the slide groove 16.
[0021] Specifically, the built-in threaded transmission mechanism of the nut slider 18 engages with the threaded electric lead screw 15, converting the rotational motion into linear motion, ensuring that the direction of movement strictly extends along the guide rail of the slide groove 16. The outer wall of the nut slider 18 maintains a sliding fit with the guide rail outside the slide groove 16, limiting lateral displacement during movement and preventing connection failure or damage to the cable terminal 19 and the battery controller 14 due to misalignment.
[0022] In practical applications, the main control module connection device for this type of split-type mobile energy storage system includes the following tasks: The exhaust box 5 is located directly above the energy storage box 1, and its bottom end is provided with exhaust holes 11 at equal intervals. The servo fan 7 is installed inside the air intake box 3. When the servo fan 7 is running, a negative pressure is formed inside the energy storage box 1, and outside air is drawn in through the exhaust holes 11 of the air intake box 3. At the same time, the air filter element 4 set on one side of the air intake box 3 purifies and filters the air intake, removes dust, impurities and other contaminants from the air, and ensures that the air entering the energy storage box 1 is clean, so as to avoid damage to the internal equipment. The exhaust box 5 is installed at the top of the door 2 and is connected to the internal space of the energy storage box 1. Hot air is discharged to the outside of the energy storage box 1 through the exhaust box 5 under the action of the servo fan 7. The air filter element 4 connected to one side of the air intake box 3 further filters the intake air to reduce impurities and odors in the exhaust air. At the same time, the fin assembly 9 installed on one side of the docking box 8 can assist in heat dissipation. Through the heat exchange between the fin assembly 9 and the air, the nut slider 18 on the bottom surface of the bottom sealing plate 13 and the electric screw 15 are in a relaxed position. The cable terminal 19 and the access port of the battery controller 14 are not in contact. When docking is triggered, the electric screw 15 is started and driven by the external control system or manual command to move the nut slider 18 linearly along the guide rail of the slide groove 16. When the electric lead screw 15 is in its initial position, the nut slider 18 moves the bottom sealing plate 13 away from the battery controller 14, the cable terminal 19 is separated from the access port, the electric lead screw 15 starts to rotate forward, the nut slider 18 moves forward along the slide groove 16, pushing the bottom sealing plate 13 and the cable terminal 19 closer to the battery controller 14 until the snap-fit connection is completed. After the cable terminal 19 is connected to the access port, the battery controller 14 establishes a communication link with the main control module to realize battery status monitoring and control command transmission. If disconnection is required, the electric lead screw 15 reverses, the nut slider 18 drives the bottom sealing plate 13 to move backward, the cable terminal 19 separates from the access port, and the bottom sealing plate 13 returns to a sealed state. The nut slider 18 drives the bottom sealing plate 13 and the cable terminal 19 at its top to move towards the battery controller 14 until the cable terminal 19 connects to the access port of the battery controller 14. After the connection is completed, the battery controller 14 transmits the status information of the lithium battery pack 17 to the main control module through the cable terminal 19, or receives the control commands from the main control module, realizing bidirectional communication and control.
[0023] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
