Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

Please refer to Figures 1 to 5. Figure 1 is a schematic diagram of the electric vehicle fire fighting device 100 of the present invention before starting; Figure 2 is an enlarged schematic diagram of the connection between the bottom plate 110 and the first side plate 122 in Figure 1; Figure 3 is a schematic diagram of the electric vehicle fire fighting device 100 of the present invention after starting; Figure 4 is a side view schematic diagram of the fourth side plate 134 of Figure 1 before starting; Figure 5 is a top view schematic diagram of the fourth side plate 134 of Figure 1 and the first side plate 122 after both are started.

The electric vehicle fire fighting device 100 includes a bottom plate 110, a first pair of side plates 120, a second pair of side plates 130, a communication unit 165, and a driving device 170. The first pair of side plates 120 includes a first side plate 122 and a second side plate 124, which are respectively disposed on the first side (upper right of the bottom plate 110) and the second side (lower left of the bottom plate 110) of the bottom plate 110. The second pair of side plates 130 includes a third side plate 132 and a fourth side plate 134, which are respectively disposed on the third side (upper left of the bottom plate 110) and the fourth side (lower right of the bottom plate 110) of the bottom plate 110. The driving device 170 is used to rotate the first pair of side plates 120 and the second pair of side plates 130 in sequence, so that the first pair of side plates 120, the second pair of side plates 130 and the bottom plate 110 form a container with an opening facing upward. The driving device 170 can be an oil pressure device, a pneumatic device, or a hydraulic device, or other devices that can drive the first pair of side plates 120 and the second pair of side plates 130 from a horizontal direction to a vertical direction. Basically, the electric vehicle fire fighting device 100 proposed in this application is installed in a general parking space, so we assume that the parking space is rectangular, so the first pair of side plates 120 and the second pair of side plates 130 of this application will form a container with an opening facing upward after rotating 90 degrees.

The communication unit 165 can be installed below the bottom plate 110 or directly above the parking space to receive and transmit signals. When the communication unit 165 receives a fire message of an electric vehicle, the driving device 170 rotates the first pair of side plates 120 and the second pair of side plates 130 in sequence, so that the first pair of side plates 120, the second pair of side plates 130 and the bottom plate 110 form a container with an opening facing upward. Basically, the electric vehicle fire fighting device 100 of the present invention is a complete product. It only needs to be connected to the existing fire detection device and fire fighting device through the communication unit 165. The fire detection device is such as a dense smoke detection device, a temperature detection device, etc.; the fire fighting device is such as a sprinkler, a foam sprinkler, etc. Basically, as long as the fire detection device detects a fire, the electric vehicle fire fighting device 100 will be activated, and it can be used with fire fighting devices such as sprinklers, foam sprinklers, etc. to achieve the effect of extinguishing fire or cooling.

Generally speaking, fire fighting equipment is usually installed above the parking space, but for fire locations such as batteries under the vehicle body, it is impossible to provide timely fire extinguishing materials such as fire or foam when the fire is small or abnormal. Therefore, the container formed by the electric vehicle fire fighting device 100 of the present application after startup can be used to receive fire extinguishing materials. When the fire accumulates from the bottom to exceed the battery or other faulty or abnormal locations under the vehicle body, the purpose of fire extinguishing can be achieved quickly in the early stage when the fire is small or abnormal.

In detail, the present application utilizes a plurality of rotating shafts 150 disposed on the first side, the second side, the third side and the fourth side of the bottom plate 110, respectively, for connecting with the first side plate 122, the second side plate 124, the third side plate 132 and the fourth side plate 134. In the preferred embodiment, the rotating shafts 150 can allow the first side plate 122, the second side plate 124, the third side plate 132 and the fourth side plate 134 to rotate to an angle close to vertical with the ground so as to form a 5-sided open box-shaped body with the bottom plate 110.

In detail, the present application utilizes a plurality of first sealing members 160 respectively disposed on the plurality of rotating shafts 150. Thus, after the first side panel 122, the second side panel 124, the third side panel 132 and the fourth side panel 134 rotate upward by 90 degrees, the four contact lines between the bottom panel 110 and the first side panel 122, the second side panel 124, the third side panel 132 and the fourth side panel 134 can achieve a sealing effect, so as to receive the fire extinguishing material and prevent it from overflowing and affecting other parking spaces.

Preferably, the present application also uses a plurality of supports 140 disposed under the base plate 110. In the preferred embodiment, three supports 140 are used, and the drive device 170, such as a motor, is buried under the base plate 110, so that the parking area of the electric vehicle can remain flat without changing the user's habits. Preferably, the height of the support is about 3-5 cm, so that there is a space below, and wireless charging equipment can be expanded and installed below the base plate 110 in the future, and the second side plate 124 will lean against the ground to form a small slope on the side away from the base plate 110 before the electric vehicle fire fighting device 100 is not started, so that the electric vehicle can drive onto the base plate 110.

Furthermore, the present application also includes a plurality of second sealing members 155, which are disposed between the first side plate 122 and the third side plate 132, between the first side plate 122 and the fourth side plate 134, between the second side plate 124 and the third side plate 132, and between the second side plate 124 and the fourth side plate 134. The plurality of second sealing members 155 are used when the driving device 170 rotates the first pair of side plates 120 and the second pair of side plates 130 in sequence, so that the first pair of side plates 120, the second pair of side plates 130 and the bottom plate 110 form a container with an opening facing upward, and the two sides of the third side plate 132 contact the first side plate 122 and the second side plate 124, respectively. 4, the two sides of the fourth side plate 134 contact the first side plate 122 and the second side plate 124 respectively, and a sealed container is formed by the second sealing member 155. Accordingly, when the fire-fighting device such as a sprinkler is started, water will accumulate in the sealed container. When the water level gradually rises, it can stop when it reaches a preset height. The preset height referred to here can be set to just flood the height of the battery of the electric vehicle chassis. According to this, it can not only be installed on the existing parking space, but also can be set according to the battery setting height of different electric vehicle models. The preset height can be prevented from overflowing due to continuous operation of the fire-fighting device and affecting other parking spaces.

Referring to FIG6 , a schematic diagram of the electric vehicle fire fighting system 200 of the present invention after being activated is shown. The components mentioned below are referred to in FIG1-5 and will not be described in detail. This schematic diagram directly illustrates a situation where a car 210 is parked on the electric vehicle fire fighting device 100. The difference between the electric vehicle fire fighting system 200 and the electric vehicle fire fighting device 100 is that the electric vehicle fire fighting system 200 also includes an electric vehicle battery abnormality detection unit 190 and a fire fighting device 180; but does not have the communication unit 165. In other words, compared to the electric vehicle fire fighting device 100 which is installed in a parking space that already has a fire fighting device and a fire detection device; the electric vehicle fire fighting system 200 is constructed as a set of abnormalities (fire) in a battery 191 of an electric vehicle. When the electric vehicle battery abnormality detection unit 190 detects that the battery 191 of the electric vehicle generates high temperature, flames or other abnormal conditions, the fire fighting device 180 connected by wire or wirelessly provides the fire extinguishing material (water or foam and other materials used for fire extinguishing) to the container to prevent the fire from further expanding.

The above is only the best implementation method of the present invention. It should be pointed out that for technicians familiar with this technical field, without departing from the principle of the present invention, they can make some improvements and embellishments, and these improvements and embellishments should also be regarded as the protection scope of the present invention.
