[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Example:

[0027] like Figures 1-5As shown, this utility model provides an integrated control device for the charging compartment of a battery swapping cabinet, including a cooling fan 1, a charger 2, and an electromagnetic lock 3, as well as a control box 4. The electromagnetic lock 3 is installed at the front end of the control box 4. The electromagnetic lock 3 is used to lock the battery charging swapping cabinet during the battery swapping process to ensure operational safety. The cooling fan 1 and the charger 2 are installed inside the control box 4. The charging controller controls the start / stop and output voltage of the battery charger 2 according to the charging progress and status of the battery. The cooling fan 1 is located above the charger 2. A baffle 5 is installed between the cooling fan 1 and the charger 2. An emergency unlocking device for opening the electromagnetic lock 3 is also installed inside the control box 4.

[0028] The emergency unlocking device can quickly open the electromagnetic lock 3 in an emergency, facilitating timely handling of emergencies and emergency repairs. It also prevents damage to the electromagnetic lock 3 in an emergency, saving the cost of replacing the electromagnetic lock 3 with a new one.

[0029] Furthermore, the top of the spoiler 5 is fixedly installed on the charger 2, and the tail is fixedly connected to the rear end of the control box 4, which enhances the stability of the spoiler 5 installation and prevents it from loosening. The width of the spoiler 5 is greater than the width of the charger 2, and the tail of the spoiler 5 is bent downward and extends horizontally outward, with a reasonable spatial layout.

[0030] The design of the spoiler 5 can separate the charger 2 and the cooling fan 1. The temperature control fan 18 of the lower charger 2 and the cooling fan 1 of the upper layer form an efficient heat dissipation airflow channel, guiding the airflow to flow along a predetermined path. This helps to distribute the airflow evenly to each heat dissipation area, ensuring that each electronic component can be fully cooled, improving heat dissipation efficiency and effect. At the same time, it can also effectively isolate the electromagnetic interference of high voltage input to each PCB board.

[0031] Furthermore, the emergency unlocking device includes a lock head 6, a linkage rod 7, and a pressure plate 8. The lock head 6 is a cylindrical lock. The lock head 6 is installed at the rear end of the control box 4. The linkage rod 7 is fixedly installed on the lock head 6. The pressure plate 8 is fixedly installed at the other end of the linkage rod 7. The pressure plate 8 presses against the control rod 9 at the rear end of the electromagnetic lock 3.

[0032] When an emergency unlocking device is needed to unlock the electromagnetic lock in an emergency, the lock head 6 is turned. The lock head 6 drives the linkage rod 7 to rotate, and the rotation of the linkage rod 7 drives the pressure plate 8 to rotate, so that the pressure plate 8 presses on the control rod 9 to unlock the electromagnetic lock 3 in an emergency.

[0033] Furthermore, a one-way valve 10 is installed on the rear side of the cooling fan 1 to prevent gas backflow, and a thermal aerosol fire extinguisher 11 and a heating plate 12 are installed on the rear side of the one-way valve 10.

[0034] A temperature sensor is used to monitor the temperature inside the charging compartment in real time. When the temperature inside the charging compartment is too high, the cooling fan 1 draws in cool air from outside and guides it into the battery charging and swapping cabinet through the one-way valve 10 to lower the temperature inside the cabinet. When the temperature inside the charging compartment is too low, the PTC heating plate 12 is activated, and the cooling fan 1 uses the one-way valve 10 to transfer heat into the charging compartment to increase the temperature inside the cabinet and ensure the stable operation of the cabinet.

[0035] By comparing the temperature of the temperature sensor inside the charging compartment with the temperature of the temperature sensor outside the cabinet, and by calling the temperature of the charging battery BMS and the data of individual cells, it is calculated whether the charging battery has thermal runaway. If thermal runaway occurs, the thermal aerosol fire extinguisher 11 placed behind the cooling fan 1 can be released. The cooling fan 1 with a one-way valve 10 guides the thermal aerosol into the charging compartment where the battery has thermal runaway, and quickly extinguishes the fire.

[0036] Furthermore, the control box 4 is also equipped with a sub-control board 13 and a lighting control board 14. The sub-control board 13 is located above the charger 2 and at the front end of the cooling fan 1. The sub-control board 13 is responsible for controlling the battery charging and swapping process, as well as monitoring the battery status and charging progress. The lighting control board 14 is used to control the opening and closing of the lighting 15 to provide lighting for the battery swapping operation.

[0037] Furthermore, the control box 4 has an air intake channel 16 connected to the cooling fan 1 on the front side, and a vent 17 connected to the cooling fan 1 on the rear side. The lighting lamp 15 is installed on the rear side of the control box 4.

[0038] Furthermore, the charger 2 is equipped with a temperature-controlled fan 18, which is connected to the air intake channel 16.

[0039] Both the temperature control fan 18 and the cooling fan 1 draw in outside air through the air intake channel 16 to cool the charger 2 and the charging compartment. At the same time, the cooling airflow generated by the cooling fan 1 enters the charging compartment through the vent 17 to cool the charging compartment. The thermal aerosol also enters the charging compartment through the vent 17 to extinguish the fire in the charging compartment.

[0040] Furthermore, the rear end of the control box 4 is equipped with multiple control interfaces 19, including a 220V pin jack, a 12V waterproof jack, and a 485 data jack. The control interface 19 adopts a quick-connect structure, which is mainly used to distinguish between strong and weak currents, receive external power supplies, and transmit modular control system data, effectively ensuring the stable operation of the equipment.

[0041] Furthermore, an indicator light 20 is installed at the front end of the control box 4. The indicator light 20 is a red and green indicator light, which is used to provide timely feedback on the charging status and charging progress of the battery.

[0042] The working principle of this embodiment is as follows:

[0043] A control box 4 is installed in each charging compartment of the battery swapping cabinet. The control box 4 integrates multiple electronic components in a modular fashion.

[0044] When the temperature inside the battery swapping cabinet is too high, the cooling fan 1 draws in cold air from the outside through the air intake channel 16. The cold air is then delivered to the battery swapping cabinet through the one-way valve 10 and the vent 17, thereby cooling the battery swapping cabinet.

[0045] When the temperature inside the battery swapping cabinet is too low, the heating plate 12 is activated, and the cooling fan 1 conducts heat to the inside of the charging compartment through the one-way valve 10 to increase the temperature inside the cabinet.

[0046] When there is a risk of thermal runaway of the battery in the charging compartment, the thermal aerosol fire extinguisher 11, which is located behind the cooling fan 1, is released. The cooling fan 1, which is equipped with a one-way valve 10, introduces the thermal aerosol into the charging compartment where the battery is thermally runaway, and quickly extinguishes the fire.
