It will be appreciated that in some cases, such as where the front side of the first housing abuts the wall, the top wall and upper side of the second housing are less spaced, and the like, certain features may be omitted or displaced as desired.

In embodiments that include a second housing 110, the extinguisher 150 may be mounted within the second housing 110 or within the first housing 160. An embodiment of a fire extinguisher 150 installed within the second housing 110 is shown in fig. 5 and 6, wherein a portion of the top wall 111 of the second housing 110 is removed to show the interior of the second housing 110. It is also contemplated that a fire extinguisher 150 is mounted within both the second housing 110 and the first housing 160. The fire extinguisher 150 may be provided at a suitable location as desired.

The fire extinguisher 150 is arranged to extinguish the fire of the charging post 100, the AGV cart 200, and the surrounding environment. Specifically, the fire extinguisher 150 is arranged to extinguish fire at a location in the charging pile 100 where a fire is easily generated, such as the power module 130, the control module 120, and the electrodes 140, the power inlet 121, and the like. During the charging of the AGV car 200, the fire extinguisher 150 also extinguishes the AGV car 200 if a fire from the AGV car is detected. Here, the fire includes that a fire has been initiated or is about to be initiated. In one embodiment, the fire extinguisher 150 is installed inside the charging pile 100. The fire extinguisher 150 has a container storing fire extinguishing material and a blaster (not shown) for blasting the container. The blasting machine can be ignited by igniting the fuse, or by an electronic igniter. The fire extinguisher 150 may be provided with both a fuse and an electronic lighter, both of which are connected to a detonator, thereby enabling ignition by either an open flame or an electronic lighter. The fire extinguishing material can be fire extinguishing dry powder or water-based fire extinguishing material and the like.

In the embodiment shown in fig. 4, the fire extinguisher 150 is mounted below the top wall 161 inside the first housing 160. The mounting means may be, for example, adhesive, hanging, or the like. The fire extinguisher 150 is installed adjacent to the power module 130 and the control module 120, thereby covering these parts when a fire occurs in the power module 130 and the control module 120 for the purpose of extinguishing the fire in these parts. Here, close refers to closer than other portions. In a variant, the extinguisher 150 may be arranged close to the power inlet 121, or close to the electrode 140, or other high power components, thereby extinguishing the fire in the corresponding location. In another embodiment, the fire extinguisher 150 is arranged to be located above the device to be charged or above the charging port of the device to be charged when the device to be charged is charged. For example, when the equipment of waiting to charge is the AGV dolly, fill electric pile and can install in the roof of second housing 110 and be close to the position of AGV dolly 200 for the fire extinguishing materials can concentrate and cover the AGV dolly, can enter into the AGV dolly inside through the trompil of AGV dolly even, thereby can put out a fire to the AGV dolly effectively, in order to prevent that the condition of a fire that the AGV dolly arouses from influencing the operation of filling electric pile. In another embodiment, a fire extinguisher 150 may be mounted on the top wall of the second housing 110 between the electrode 140 and the AGV cart to be able to cover the electrode and AGV cart to effectively extinguish the fire at the same time.

The detonator in the extinguisher 150 may have at least one detonator (not shown), typically a plurality of detonators. The fuse can be ignited when a fire occurs in the charging pile or the AGV and creates an open flame. Thereby, the fire extinguisher 150 is ignited. The ends of each fuze may be disposed at one or more of the power module 130, the control module 120, the power access port 121, the electrodes 140, respectively. In some embodiments, the blaster of the fire extinguisher 150 may also be provided with an electronic lighter (not shown). The electronic sparker is electrically connected to the control module 120 via an electrical wire. The electronic lighter decides whether to ignite according to the instruction from the control module 120 to ignite the fire extinguisher. When the control module 120 determines that a fire occurs in the charging pile 100 or the AGV 200, the corresponding fire extinguisher 150 is ignited. For example, when the control module 120 determines that a fire occurs in the AGV 200, a blaster near the AGV 200 is detonated without affecting the normal operation of the charging pile 100.

In one embodiment, the charging post is further provided with a sensor system, and the control module detonates a fire extinguisher in the first housing and/or a fire extinguisher in the second housing according to the fire information detected by the sensor system. The sensor system includes one or more of a smoke sensor 21, a temperature sensor 22 and a light sensor 23. The smoke sensor 21 is arranged to detect smoke generated from the charging post 100 or the AGV cart 200 and is electrically connected to the control module 120 such that the control module 120 controls the blaster to fire the fire extinguisher 150 when the smoke sensor 21 detects the occurrence of smoke. The smoke sensor 21 may be disposed on a lower surface of the top wall 161 of the first housing 160, on a circuit board of the control module 120, on a lower surface of the top wall 111 of the second housing 110, or in other suitable locations. The temperature sensor 22 is arranged to detect the control module 120 and/or the power module 130 or the top wall of the second housing 110 and is electrically connected to the control module 120 such that the control module 120 controls the blaster to fire the fire extinguisher when the temperature sensor 22 detects a temperature above a preset threshold. The temperature sensors 22 are typically mounted on the surface of the control module 120, the power module 130, and monitor the temperature of these components in real time. When the temperature sensor 22 is mounted on the second housing 110, the temperature around the mounting position can be monitored in real time. The light sensor 23 is disposed to detect an abnormal light source, such as a spark, etc., generated from the charging pile 100, and is electrically connected to the control module 120, so that the control module 120 controls the blaster to fire the fire extinguisher 150 when the light sensor 23 detects the occurrence of the abnormal light source.

Each type of sensor can be installed respectively in the part department that needs the control, will detect data transmission and judge for the control module who fills electric pile 100, and the detection data is temperature, light intensity, smog concentration etc. respectively. The specific judgment mode can be that a single sensor sets a threshold value according to actual experience, or weights are distributed to all sensors according to actual experience to carry out combined judgment. In one embodiment, the control module of the charging post 100 may determine the fire source based on the position of the sensor transmitting the detection data (e.g., the sensor position obtained by the sensor ID), which may include, for example, the charging post itself, the AGV cart, or other fire point. In another embodiment, the charging pile 100 can determine the fire source by combining the positions of the sensors and the detection data transmitted by the sensors. In other embodiments, the fire source may be determined by other fire source information. The control module determines whether to ignite the fire extinguisher, which fire extinguisher to ignite, whether to send an alarm, whether to cut off the power supply, and the like according to the judgment result. The fire extinguisher is detonated by taking the position of the sensor and/or the detection data of a plurality of sensors into consideration, so that the detonation accuracy can be improved.

In one embodiment, the charging post 100 may also have an alarm module and a communication module. The alarm module has a horn and/or a warning light, etc., and is arranged to send an alarm signal when a fire occurs in the charging pile 100 or a fire hazard is detected. The communication module is arranged to send the fire information of the charging pile 100 and/or the AGV trolley 200 to the background monitoring system, receive instructions from the background monitoring system and send the instructions to the control module 120, and the control module 120 decides whether to fire the fire extinguisher according to the instructions. In particular, the communication module can adopt a bus communication module. The communication module transmits the acquired information to the background monitoring system, and the data is presented through the background monitoring system. And when the data is abnormal, an alarm is sent to remind, and when the personnel judge that the fire is in the process of passing through the monitoring system, a one-key detonation instruction can be sent to trigger the electronic trigger detonation device to detonate the fire extinguisher 150, so that the fire extinguishing function is realized. Here, the fire information may include temperature information, light information, smoke information, and/or fire source information. In another embodiment, when a fire occurs or a fire hidden danger is detected, the communication module sends an alarm signal to the background monitoring system, and personnel judge the fire through the monitoring video and send an instruction to the control module. In another embodiment, when a fire occurs or a fire hazard is detected, the personnel can judge by combining the information collected by the sensor system and the monitoring video. When the sensor data is abnormal, the background further confirms the fire and then detonates the fire extinguisher 150, so as to prevent the false triggering of the fire extinguisher caused by the abnormal data caused by other non-fire conditions.

According to the charging pile 100, the fire can be quickly extinguished when the fire occurs, and the safety of the surrounding environment of the charging pile is ensured. It is understood that the above description of the specific embodiments has been made by taking an AGV cart as an example, but other devices to be charged other than an AGV cart may be used.
