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.

[0031] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a mobile energy storage vehicle liquid-cooled battery box, including a frame 1. A liquid cooling mechanism 2 is installed on the right side of the inner wall of the frame 1 for liquid cooling heat dissipation. A ventilation mechanism 3 is fixedly connected to the bottom wall of the frame 1 for ventilation heat dissipation. A monitoring cabinet 4 is installed on the top right side of the frame 1. The monitoring cabinet 4 collects data from the components of the liquid cooling mechanism 2 in real time through a sensor module. After the data is transmitted to the control unit, it is analyzed and judged against a preset threshold. If the data is abnormal, an early warning is immediately triggered and a control command is generated to execute the corresponding component adjustment. At the same time, the monitoring cabinet will... Real-time and historical data are uploaded to a remote platform for easy maintenance. A power supply cabinet 5 is fixedly connected to the top left side of the chassis 1. The power supply cabinet 5 has built-in voltage and current sensors to monitor output power parameters in real time. In case of overload, short circuit, or abnormal voltage, the protection module immediately cuts off the fault circuit to prevent equipment damage. Simultaneously, operating data is transmitted to the monitoring cabinet 4, allowing operators to monitor the power status and power the system. The liquid cooling mechanism 2 includes a carriage 201, which is fixedly connected to the top of the outer wall of the chassis 1. An air pump 202 is fixedly connected to the top right side of the carriage 201. The air pump 202 rotates in the middle of its inner wall. A blade 203 is dynamically connected, and a condenser 204 is installed on the rear side of the outer wall of the blade 203. The condenser 204 is a shell-and-tube condenser TB-28. A connecting pipe 205 is connected to the bottom of the outer wall of the condenser 204, and a tee pipe 206 is connected to the other side of the connecting pipe 205. An adjusting assembly 207 is fixedly connected to the top left side of the air pump 202. The adjusting assembly 207 includes a slide rail 2071, which is fixedly connected to the front and rear sides of the top of the carriage 201. A motor 2073, model YB3-160M, is fixedly connected to the middle of the inner wall of the air pump 202. -4. The output end of motor 2073 is fixedly connected to wheel 1 2074. Wheel 1 2074 is rotatably connected to one side of its outer wall. Wheel 2076 is rotatably connected to the bottom of the inner wall of carriage 201. Wheel 1 2074 is connected to wheel 2 2076 via belt 2075. Wheel 2 2076 is fixedly connected to one side of its outer wall. Folding frame 2078 is rotatably connected to the left side of the outer wall of pulling rope 2077. Branch pipe 2072 is rotatably connected to both the front and rear sides of the outer wall of folding frame 2078. Branch pipe 2072 is connected to the left side of the outer wall of three-way pipe 206.

[0032] Specifically, the power supply cabinet 5 on the left side of the frame 1 supplies power to the system, while the monitoring cabinet 4 on the right side monitors equipment operation to ensure safety. The ventilation mechanism 3 on the inner bottom wall provides initial cooling for the battery box, while the liquid cooling mechanism 2 on the right side of the inner wall mainly enhances cooling for the heat dissipation unit, thus avoiding low cooling efficiency. In the liquid cooling mechanism 2, the compartment 201 is fixed to the top of the frame 1, and the air pump 202 on the top right side is started, causing the inner wall blades 203 to rotate and accelerate airflow. The condenser 204 behind the blades 203 achieves rapid cooling, and the cold air flows through the connecting pipe 205 to the three-way pipe 206 and then to the branch pipe 2072. At the same time, the adjustment component 207 on the top left of the air pump 202 adjusts the heat dissipation coverage: the motor 2073 drives the first rotating wheel 2074, which in turn drives the second rotating wheel 2076 via the belt 2075. The second rotating wheel 2076 pulls the pull rope 2077 to extend and retract the folding frame 2078, which in turn moves the branch pipe 2072, ensuring that the heat dissipation coverage accurately corresponds to the high-heat area, and that the fan airflow matches the heat dissipation requirements. Ultimately, the liquid cooling mechanism 2 and the ventilation mechanism 3 work together to dissipate heat, balancing maintenance and structural stability, and ensuring the efficient operation of the energy storage battery box.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The ventilation mechanism 3 includes a connecting pipe 301, which is fixedly connected to the top left side of the air pump 202. Multiple heat dissipation pipes 302 are connected to the left side of the outer wall of the connecting pipe 301. A guide pipe 304 is rotatably connected to the adjacent side of the outer wall of the heat dissipation pipe 302. A fixing block 303 is fixedly connected to the side of the outer wall of the heat dissipation pipe 302 away from it. A drive assembly 305 is fixedly connected to the middle of the inner wall of the fixing block 303. The drive assembly 305 includes a motor 3051, which is fixedly connected to one side of the outer wall of the fixing block 303. A gear 3052 is fixedly connected to the output end of the motor 3051. The gear 3052 is rotatably connected to the bottom of the inner side of the fixing block 303. A rack 3053 passes through the middle of the inner side of the gear 3052. The rack 3053 meshes with the gear 3052. A connecting rod 3054 is fixedly connected to the adjacent side of the outer wall of the gear 3052. The connecting rod 3054 is fixedly connected to the guide pipe 304.

[0034] Specifically, in the ventilation mechanism 3, the connecting pipe 301 is fixed to the top left side of the air pump 202, receiving hot air from the surrounding area and the system, and initially dissipating heat through the heat dissipation pipe 302; when the ventilation direction needs to be adjusted, the drive component 305 in the fixed block 303 is started, the motor 3051 drives the gear 3052 to rotate, the meshing rack 3053 is linked, and the guide pipe 304 is rotated through the connecting rod 3054 to realize the adjustment of the ventilation angle, and accurately guide the hot air to the heat dissipation plate 12 or the exhaust hole 11. In conjunction with other heat dissipation structures, the heat dissipation efficiency is improved and the equipment is kept stable.

[0035] Reference Figure 1 , Figure 2 and Figure 3A charging pile 6 is fixedly connected to the left side of the outer wall of the power supply cabinet 5. A high-voltage box 7 is fixedly connected to the middle of the inner wall of the air pump 202. Through the shunt box on the outer wall of the high-voltage box, the power is accurately distributed to each high-power power-demanding component to ensure that each unit obtains power as needed. At the same time, the high-voltage box has built-in voltage and current sensors and overvoltage and overcurrent protection modules to monitor power parameters in real time. If an abnormal situation occurs, the protection module immediately cuts off the circuit to prevent damage to the components. A shunt box 8 is fixedly connected to the front side of the outer wall of multiple high-voltage boxes 7. A battery block 9 is fixedly connected to the inner side of the high-voltage box 7. An exhaust hole 11 is opened on the right side of the top of the carriage 201. An output cabinet 10 is fixedly connected to the left side of the top of the frame 1. A heat sink 12 is fixedly connected to the right side of the outer wall of the air pump 202. Multiple screws 13 are threaded around the outer wall of the heat sink 12.

[0036] Specifically, the output cabinet 10 on the top left of the frame 1 provides power to external devices. After receiving power, the power supply cabinet 5 can charge the devices via the charging pile 6 fixed on its outer left side. The air pump 202 provides air pressure support to related components. Meanwhile, the high-voltage box 7 fixed in the middle of its inner wall processes the power. The battery block 9 inside the high-voltage box 7 is responsible for storing and releasing electrical energy, ensuring the system's high power requirements. The distribution box 8 on the front of the outer wall of the multiple high-voltage boxes 7 is responsible for power distribution, accurately distributing the electrical energy output from the high-voltage boxes 7 to each power-requiring component, ensuring the orderly operation of each unit. The heat generated during system operation is dissipated through the heat dissipation plate 12 on the outer right side of the air pump 202. The heat dissipation plate 12 is firmly fixed by screws 13 around it, ensuring stable heat dissipation. The exhaust vent 11 on the top right of the carriage 201 helps to expel the hot air accumulated inside the system, further maintaining the stable internal temperature of the equipment and preventing high temperatures from affecting the performance and lifespan of components, ultimately achieving efficient and safe operation of the entire system.

[0037] Working principle: The power supply cabinet 5 on the top left of the frame 1 provides power to the entire system, while the monitoring cabinet 4 on the top right monitors the equipment's operating status in real time to ensure system safety. The ventilation mechanism 3 on the inner bottom wall initially dissipates heat from the battery box through ventilation, while the liquid cooling mechanism 2 on the inner right wall improves heat dissipation through liquid cooling. The two work together to avoid low heat dissipation efficiency. In the specific operation of the liquid cooling mechanism 2, the compartment 201 is fixed to the top of the frame 1. After the air pump 202 on the top right is started, the blades 203 in the middle of the inner wall rotate, accelerating airflow. The condenser 204 on the rear side of the outer wall of the blades 203 cools the air. The cooled air is then cooled by the connection at the bottom of the outer wall. The air is supplied from the pipe 205 to the three-way pipe 206, and then split to the branch pipe 2072. The adjustment component 207 on the top left of the air pump 202 can adjust the heat dissipation coverage: the motor 2073 drives the first rotating wheel 2074 to rotate, and drives the second rotating wheel 2076 through the belt 2075. The second rotating wheel 2076 pulls the pull rope 2077, which causes the folding frame 2078 to extend and retract, thereby driving the branch pipe 2072 to move. This ensures that the heat dissipation coverage of the branch pipe 2072 accurately corresponds to the high heat generation area of ​​the battery box, and the fan airflow matches the battery heat dissipation requirements. The liquid cooling mechanism 2 and the ventilation mechanism 3 work together to dissipate heat, taking into account both maintenance convenience and structural stability, and ensuring the efficient operation of the energy storage battery box.

[0038] The connecting pipe 301 of the ventilation mechanism 3 is fixed to the top left side of the air pump 202. It can receive hot air from the vicinity of the air pump 202 or inside the system, and then perform initial heat diffusion through multiple heat dissipation pipes 302 connected to the left side of the outer wall. When it is necessary to adjust the ventilation direction to improve the heat dissipation, the drive component 305 on the inner wall of the fixing block 303 is activated. The motor 3051 drives the gear 3052 to rotate, and the rack 3053 meshing with the gear 3052 is linked accordingly. Then, through the connecting rod 3054, the guide pipe 304 on the adjacent side of the heat dissipation pipe 302 is rotated to realize the adjustment of the ventilation angle, so that the hot air is more accurately guided to the heat dissipation plate 12 or the exhaust hole 11. With the cooperation of the heat dissipation structure, the heat dissipation efficiency of the system is further improved, ensuring the stable operation of the equipment.
