[0002] With the increasing number of electric bicycles, especially those equipped with lithium batteries, fires caused by electric bicycles are becoming increasingly frequent. The primary ignition point for electric bicycle fires is the lithium battery, which is particularly prone to explosions when charging. Once a lithium battery catches fire, the flames can rapidly grow and be difficult to extinguish. They can easily ignite surrounding batteries or other flammable materials, causing widespread and potentially fatal fires that harm innocent people and pose a serious threat to public life and property.

[0003] Traditional preventive measures include setting up fire isolation, spraying water, blasting fire and other methods, which are difficult to put out in time. Therefore, there is an urgent need for a safe charging device that can detect and extinguish fires in time. Utility Model Content

[0005] In order to solve the above technical problems, the technical solutions of the present utility model are as follows:

[0006] A battery safety charging device includes a charging cabinet, a controller, and a fire-fighting vehicle. The charging cabinet includes multiple charging compartments for accommodating charged batteries. The charging compartments are provided with outlets for discarding batteries. The charging compartments are provided with temperature sensors, charging sockets, and battery discarding mechanisms. The temperature sensor is electrically connected to the input end of the controller, the charging socket is connected to external AC power, the battery discarding mechanism is transmission-connected to the battery, and the battery discarding mechanism is also electrically connected to the output end of the controller. The fire-fighting vehicle includes an automatic guided vehicle and a fire-extinguishing container carried by the vehicle.

[0007] Furthermore, the charging cabinet is a hollow rectangular parallelepiped, with multiple horizontal partitions and multiple vertical partitions arranged inside. The charging cabinet is divided into multiple layers by the horizontal partitions, and each layer is divided into multiple charging compartments by the vertical partitions.

[0008] Furthermore, the temperature sensor is arranged at the top of the charging compartment.

[0009] Furthermore, a power relay is provided at the charging socket, and the power relay is electrically connected to the output end of the controller.

[0010] Furthermore, a rear door is provided at the disposal outlet of the charging bin, and the rear door is hinged to a side wall of the charging bin.

[0011] Furthermore, the bottom surface of the charging compartment is inclined downward toward the rear compartment door, and the battery disposal mechanism includes a first electromagnetic lock. The rear compartment door is locked to the other side wall of the charging compartment through the first electromagnetic lock, and the first electromagnetic lock is electrically connected to the output end of the controller.

[0012] Furthermore, a pulley for carrying batteries is provided in the charging compartment. The pulley is flat and has a plurality of rollers at its bottom.

[0013] Furthermore, the charging compartment is also provided with a front compartment door for storing and accessing batteries, and a second electromagnetic lock is provided at the front compartment door.

[0025] like Figure 1-4 As shown, this embodiment discloses a battery safety charging device, including a charging cabinet 1, a controller 2 and a fire-fighting vehicle 3. The charging cabinet 1 includes a plurality of charging compartments 102 for accommodating charging batteries 101. The charging compartments 102 are provided with a disposal outlet for discarding the batteries 101. A temperature sensor 4, a charging socket 5 and a battery disposal mechanism are provided in the charging compartment 102. The temperature sensor 4 is electrically connected to the input end of the controller 2, the charging socket 5 is connected to the external AC power, the battery disposal mechanism is transmission-connected to the battery 101, and the battery disposal mechanism is also electrically connected to the output end of the controller 2; the fire-fighting vehicle 3 includes an automatic guided vehicle 301 and a fire-extinguishing container 302 carried by it. The automatic guided vehicle 301 is communicatively connected to the controller 2, and the fire-extinguishing container 302 contains a liquid for burying the batteries 101.

[0026] The operating principle of the battery safety charging device of this embodiment is as follows: the multiple charging compartments 102 of the charging cabinet 1 can accommodate multiple batteries 101 for charging. The temperature sensor 4 is used to monitor the temperature within the charging compartments 102 and transmit the information to the controller 2. If the temperature within the charging compartment 102 exceeds a certain value (e.g., 68°C), it indicates that the temperature is too high and the battery 101 is about to ignite. The controller 2 then communicates with the automatic guided vehicle 301 to move it below the discharge port of the charging compartment 102. The controller 2 also controls the battery discharge mechanism to discharge the battery 101 from the discharge port and drop it into the fire extinguishing container 302 of the fire extinguishing vehicle 3. The battery 101 is completely submerged in the liquid in the fire extinguishing container 302, interrupting combustion and thus extinguishing the fire. Therefore, the battery safety charging device of this embodiment can promptly detect whether the battery 101 is about to ignite or has already ignited, and can promptly submerge the battery 101 to extinguish the fire. Moreover, the fire extinguisher vehicle 3 is small in size and easy to move. If the battery 101 in a charging compartment 102 catches fire, the fire extinguisher vehicle 3 can be moved to the bottom of the disposal outlet of the charging compartment 102. Therefore, there is no need to set up a large immersion tank, which reduces the overall footprint of the device.

[0027] It should be noted that the controller 2 adopts a single chip microcomputer. Currently, the single chip microcomputers commonly used in the market can meet the use requirements.

[0028] It should be noted that the automatic guided vehicle 301 communicates with the controller 2 via a wireless communication module. The automatic guided vehicle 301 (AGV) is an industrial vehicle that is automatically controlled and driven by a battery as a power source. It can automatically drive to a designated location according to a set route. The guidance technology of the automatic guided vehicle 301 is relatively mature, and its guidance methods are diverse, mainly including electromagnetic induction technology, laser detection technology, ultrasonic detection technology, light reflection detection technology, inertial navigation technology, image recognition technology and coordinate recognition technology. This embodiment adopts optical detection technology to guide the operation of the AGV, specifically, laying a color ribbon with a stable reflectivity on the operation path. The vehicle is equipped with a photoelectric sensor that emits a light source and receives reflected light, and adjusts the direction of the vehicle by comparing the detected signals.

[0029] In practice, the charging cabinet 1 is a hollow rectangular parallelepiped with multiple horizontal and vertical partitions. The horizontal partitions divide the charging cabinet 1 into multiple layers, and each layer is further divided into multiple charging compartments 102 by vertical partitions. The partitions are coated or bonded with a fireproof and heat-insulating layer. If a battery 101 in one charging compartment 102 spontaneously ignites, the fireproof and heat-insulating layer can prevent the fire from spreading to adjacent charging compartments 102.

[0030] In a specific implementation, the temperature sensor 4 is disposed at the top of the charging compartment 102. When the temperature of the battery 101 rises, it heats the air around it. The temperature sensor 4 of this embodiment represents the temperature of the battery 101 by measuring the temperature of the air.

[0031] In a specific implementation, a power relay 6 is provided at the charging socket 5, and the power relay 6 is electrically connected to the output terminal of the controller 2. The controller 2 controls the power relay 6 to control the battery 101 to be connected or disconnected from charging.

[0032] During the specific implementation process, a rear door 103 is provided at the disposal outlet of the charging compartment 102 , and the rear door 103 is hinged to a side wall of the charging compartment 102 .

[0033] like Figure 5 As shown, in the specific implementation process, the bottom surface of the charging compartment 102 is tilted downward toward the rear compartment door 103, and the battery disposal mechanism includes a first electromagnetic lock 7. The rear compartment door 103 is locked to the other side wall of the charging compartment 102 through the first electromagnetic lock 7, and the first electromagnetic lock 7 is electrically connected to the output end of the controller 2.

[0034] In practice, the charging compartment 102 is further provided with a trolley 9 for carrying the battery 101. The trolley 9 is flat and has a plurality of rollers on its bottom. The rollers on the bottom of the trolley 9 provide very low friction with the bottom of the charging compartment 102. Therefore, when the rear compartment door 103 is opened, the trolley 9 can slide out of the rear compartment door 103 carrying the battery 101.

[0035] It should be noted that electromagnetic locks utilize the principle of electromagnetism. When current passes through a silicon steel sheet, the electromagnetic lock generates a strong suction force, firmly adsorbing the iron plate and effectively locking the door. Even a small current generates a strong magnetic force, and when the power is removed, the electromagnetic lock loses its suction force, allowing the door to be opened. When the temperature sensor 4 detects an overtemperature, the controller 2 de-energizes the first electromagnetic lock 7, opening the rear door 103 and allowing the battery 101 to slide toward the rear door 103 and be discarded through the disposal outlet.

[0036] In a specific implementation, the charging compartment 102 is further provided with a front door 104 for storing and accessing the batteries 101. A second electromagnetic lock 8 is provided on the front door 104. The front door 104 is hinged to one side wall of the charging compartment 102 and locked to the other side wall of the charging compartment 102 via the second electromagnetic lock 8. The second electromagnetic lock 8 is electrically connected to the output terminal of the controller 2. The controller 2 controls the second electromagnetic lock 8 to open and close the front door 104, making it easier for the user to store or remove the batteries 101.

[0037] In the specific implementation process, the charging compartment 102 also reserves space for placing the charger 10. Since different battery 101 models match different charger 10 models, the reserved space for the charger 10 is convenient for users to use their own charger 10 to charge the battery 101. Example 2

[0038] In Example 1, the battery 101 slides out of the charging compartment 102 using the gravity of the battery 101 and the pulley 9. Therefore, the bottom surface of the charging compartment 102 needs to be tilted downward toward the rear compartment door 103. This example provides an alternative implementation, in which the bottom surface of the charging compartment 102 can be horizontal. In this example, the battery ejection mechanism includes a battery ejection unit, which is in transmission connection with the battery 101 and is also electrically connected to the output of the controller 2. The battery ejection unit is a pneumatic push rod, a pneumatic push rod, or a hydraulic push rod.

[0039] In this embodiment, it is not necessary to set the bottom surface of the charging compartment 102 to be inclined downward toward the rear compartment door 103 , so the structure of the charging compartment 102 is more regular.

[0040] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
