[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the accompanying drawings:

[0033] Figure 1 This is a structural schematic diagram of an embodiment of a charging pile according to the present invention;

[0034] Figure 2 This is a schematic diagram of another embodiment of a charging pile according to the present invention. Detailed Implementation

[0035] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] like Figure 1 The image shows an embodiment of a charging pile according to the present invention. Figure 1 The embodiment of a charging pile of the present invention shown includes: a cabinet 110 for placing a charging function module, a platform 210 for placing the cabinet 110, a liquid container 220 disposed below the platform 210 for containing fire extinguishing liquid; a door panel disposed on the side of the platform 210 near the cabinet 110, and a downward passage disposed on the lower side of the door panel and communicating with the liquid container 220. Figure 1(Not marked in the text) A door panel drive module 240 is installed on the door panel to drive the door panel to open or close; a switch module 250 is connected between the power input terminal of the charging function module and the external power supply; and a controller 260 is used. The controller 260 is connected to the switch module 250 and the door panel drive module 240. When a preset trigger command is received, the controller 260 sequentially triggers the switch module 250 to open and the door panel drive module 240 to drive the door panel to open. When the door panel is closed, the cabinet 110 is placed on the placement platform 210 through the door panel. When the door panel is open, the liquid container 220 is entered through the downward passage.

[0037] Specifically, the charging pile includes a cabinet 110 and a charging function module. The charging function module is located inside the cabinet 110, which is placed on a platform 210. A liquid container 220 containing fire extinguishing liquid is located below the platform 210. A door panel is located on the side of the platform 210 closest to the cabinet 110. The cabinet 110 is supported by the door panel when on the platform 210. A downward passage is located below the door panel. When the door panel is opened, the cabinet 110 loses its support on the platform 210 and slides down into the liquid container 220 through the downward passage. The opening and closing of the door panel is controlled by a door panel drive module 240 according to control commands generated by a controller 260. The charging pile also includes a switch module 250, which is controlled to be turned on or off according to control commands from the controller 260. When the switch module 250 is on, external power can supply power to the power input terminal of the charging function module through the on-state switch module 250, allowing the charging function module to operate normally, and the charging cabinet also enters normal operating mode. When the switch module 250 is turned off, the charging cabinet cannot perform charging operations, which is equivalent to cutting off the power to the charging function module.

[0038] Based on this charging station, in the event of a fire, the controller 260 can receive a preset trigger command to control the switch module 250 to disconnect and the door panel drive module 240 to activate, thereby powering down the charging function module. The module then falls into the liquid containment tank 220 along with the cabinet 110 to extinguish the fire. The charging function module can be composed of commonly used circuits or functional modules, and is not limited here. In other words, all working circuits inside the charging cabinet 110 can be simultaneously defined as the charging function module.

[0039] In one embodiment, the liquid container 220 is a water tank, and the fire extinguishing liquid it contains is water, meaning that water is used to extinguish the fire in the cabinet 110. In other embodiments, other fire extinguishing liquids may be used. Inert gases may also be used to achieve fire extinguishing.

[0040] In one embodiment, the placement platform 210 is located on the ground, and the liquid container 220 is located underground. To make the charging cabinet convenient to use, the placement platform 210 can be placed on the ground, that is, the cabinet body 110 of the charging cabinet is placed on the ground, which does not affect the normal use of the charging cabinet. The liquid container 220 is located underground and covered by a shelter so as not to affect the surrounding environment of the charging pile.

[0041] Furthermore, in this invention, the controller 260 is located on the outside of the cabinet 110 and is composed of a commonly used MCU chip and its peripheral circuits. When the controller 260 receives a trigger command, it can output the corresponding level to trigger the operation of the switch module 250 and the door panel drive module 240 through its interface. The internal software processing is not limited here; that is, the process by which the controller 260 receives the trigger command and generates the control level can be implemented using commonly used technologies.

[0042] Optionally, the charging pile provided by this utility model further includes: a smoke sensor 120 disposed inside the cabinet 110 for generating a smoke sensing signal when smoke is generated inside the cabinet; and a controller 260 connected to the smoke sensor 120 for generating a preset trigger command based on the smoke sensing signal when receiving the smoke sensing signal. Specifically, the smoke sensor 120 is disposed inside the cabinet 110 to detect the smoke concentration in the cabinet 110, and generates a corresponding smoke sensing signal when smoke is detected inside the cabinet 110. The controller 260 is connected to the smoke sensor 120, and upon receiving the smoke sensing signal, determines that there may be a fire inside the charging cabinet 110, and then generates a preset trigger command.

[0043] Optionally, the charging pile provided by this utility model further includes: a temperature sensor 130 disposed inside the cabinet 110 for generating a temperature sensing signal based on the temperature inside the cabinet; and a controller 260 connected to the temperature sensor 130 for generating a preset trigger command based on the temperature sensing signal and the smoke sensing signal. Specifically, the temperature sensor 130 can also be disposed inside the cabinet 110 to detect the temperature inside the cabinet 110 and obtain the corresponding temperature sensing signal. The controller 260 receives the temperature sensing signal and simultaneously judges the temperature sensing signal and the smoke sensing signal to output a preset trigger command. That is, when the temperature inside the cabinet 110 reaches a certain value and the corresponding temperature sensing signal reaches a certain amplitude, the controller 260 will respond to the smoke sensing signal.

[0044] Optionally, the charging pile provided by this utility model further includes: a liquid level sensor 270 disposed in the liquid container 220, used to generate a liquid level sensing signal based on the solution height in the liquid container 220; and a controller 260 connected to the liquid level sensor 270, used to generate liquid level information when receiving the liquid level sensing signal. Specifically, a liquid level sensor 270 can also be disposed inside the liquid container 220 to detect the liquid height inside the liquid container 220. That is, in order to ensure that there is fire extinguishing liquid inside the liquid container 220 when the cabinet 110 falls into the liquid container 220, it is necessary to monitor the liquid level height inside the liquid container 220. This detection process can be triggered periodically or before generating a preset trigger command.

[0045] In one embodiment, the height of the liquid level sensor 270 within the liquid container 220 is greater than or equal to the height of the cabinet 110. That is, to ensure the cabinet 110 is completely submerged in the extinguishing liquid, the height of the liquid level sensor within the liquid container 220 must be greater than or equal to the height of the cabinet 110 to confirm whether the liquid level in the container meets the requirements. An alarm message is generated when the requirements are not met to remind the user to take corresponding replenishment measures.

[0046] In one embodiment, such as Figure 2 As shown, the door panel drive module 240 includes a motor drive chip 241, a motor 242, and a connecting component (not shown in the figure). The motor is connected to the door panel via the connecting component and is used to drive the door panel to open or close. The motor drive chip 241 is connected to the controller 260 and the motor 242 to receive control signals generated by the controller 260 to drive the motor 242. Specifically, in the door panel drive module 240, the motor drive chip 241 receives the corresponding drive level of the control signal generated by the controller 260 and drives the motor 242 to open or close the door panel via the connecting component connected to the door panel.

[0047] Furthermore, the door panel includes a first door panel 231, a second door panel 232, and a connecting assembly including a solid gear 243, a first rack 2441, a second rack 2442, a first fixed bracket 2451, a second fixed bracket 2452, a first limit switch 2461, and a second limit switch 2462; the first fixed bracket 2451 connects the first door panel 231 and the first rack 2441, and the second fixed bracket 2452 connects the second door panel 232 and the second rack 2442; the solid gear 243 is disposed between the first rack 2441 and the second rack 2442, and the motor is connected to the solid gear 243 for driving. The solid gear 243 rotates to drive the first rack 2441 and the second rack 2442 to move towards each other or away from each other; wherein the first door panel 231 and the second door panel 232 move towards each other to close the door, and move towards each other to open the door when the first rack 2441 and the second rack 2442 move away from each other; the first limit switch 2461 is correspondingly provided with the first rack 2441 to limit the closing position of the first door panel 231 and the second door panel 232; the second limit switch 2462 is correspondingly provided with the second rack 2442 to limit the opening position of the first door panel 231 and the second door panel 232.

[0048] Specifically, the door panel includes a sliding door composed of a first door panel 231 and a second door panel 232. A motor drives a solid gear 243 to rotate, which in turn moves a first rack 2441 and a second rack 2442. When the door needs to be opened, the first rack 2441 and the second rack 2442 move in opposite directions. The first door panel 231 is fixedly connected to the first rack 2441 via a first fixed bracket 2451. The movement of the first rack 2441 moves the first door panel 231 in the same direction. The second door panel 232 is fixedly connected to the second rack 2442 via a second fixed bracket 2452. The movement of the second rack 2442 moves the second door panel 232 in the same direction. The first door panel 231 and the second door panel 232 form an opening action. At this time, the movement range of the second rack 2442 is limited by a second limit switch 2462, thereby limiting the opening range. The second limit switch 2462 may include a position sensing chip connected to the motor drive chip 241. When the second limit switch 2462 is triggered, the motor drive chip 241 receives a corresponding sensing signal and stops driving the motor. When the door needs to be closed, the first rack 2441 and the second rack 2442 move in opposite directions. The first door panel 231 is fixedly connected to the first rack 2441 via the first fixed bracket 2451. The movement of the first rack 2441 drives the first door panel 231 to move in the same direction. The second door panel 232 is fixedly connected to the second rack 2442 via the second fixed bracket 2452. The movement of the second rack 2442 drives the second door panel 232 to move in the same direction. The first door panel 231 and the second door panel 232 form a closing action. At this time, the first limit switch 2461 limits the movement range of the first rack 2441, thereby limiting the closing range. The first limit switch 2461 may include a position sensing chip connected to the motor drive chip 241. When the first limit switch 2461 is triggered, the motor drive chip 241 receives the sensing signal and stops driving the motor.

[0049] In one embodiment, a manual switch 246 can also be configured to trigger the opening and closing actions of the first and second door panels. That is, the motor drive chip 241 triggers the motor to perform the corresponding action based on the trigger signal received from the manual switch 246.

[0050] In another embodiment, the door panel further includes a revolving door composed of a first door panel 231 and a second door panel 232. When the first door panel 231 and the second door panel 232 are in a closed state, they can be rotated downwards along the descending passage by a motor and corresponding connecting components to open the door. When the first door panel 231 and the second door panel 232 are in an open state, they can be moved simultaneously upwards along the descending passage by a motor and corresponding connecting components to close the door.

[0051] Optionally, in a charging pile provided by this utility model, the switch module 250 includes a circuit breaker; the input terminal of the circuit breaker is connected to an external AC input, the output terminal of the circuit breaker is connected to the power input terminal of the charging function module, and the control terminal of the circuit breaker is connected to the controller 260. Specifically, the switch module 250 is composed of circuit breakers, and the controller 260 outputs a control level to control the circuit breaker to turn on or off. The circuit breaker can be installed in the distribution box at the front of the charging cabinet, separate from the cabinet body 110. The circuit breaker can be a multi-circuit breaker, used to connect to the neutral and three-phase input lines respectively.

[0052] In one embodiment, the charging function module inside the charging cabinet includes a communication module 140. Sensors such as a smoke sensor 120 and a temperature sensor 130 installed inside the cabinet 110 can acquire signals through the internal communication module 140 and communicate with the controller 260 to transmit signals.
