[0030] Specifically, the new energy fire extinguishing system disclosed in the present utility model mainly includes a fire extinguishing platform 5; the fire extinguishing platform 5 is a carrier for arranging the fire extinguishing pipeline 7-1; it facilitates the subsequent arrangement of each component. At the same time, in the present utility model, the fire extinguishing platform 5 is generally arranged directly above the battery pack 8, and the fire extinguishing platform 5 is installed under the chassis. And in the present utility model, a fire extinguishing pipeline 7-1 is provided on the fire extinguishing platform 5; a liquid supply structure is provided on the fire extinguishing platform 5; the liquid supply structure is used to supply water to the fire extinguishing pipeline 7-1 on the fire extinguishing platform 5; an outlet is provided on the fire extinguishing pipeline 7-1. During subsequent use, the liquid supply mechanism supplies a fire extinguishing medium into the fire extinguishing pipeline 7-1, the fire extinguishing medium flows in the fire extinguishing pipeline 7-1, and then is discharged through the corresponding outlet, thereby realizing the fire extinguishing operation for the corresponding area.

[0031] Furthermore, in the present utility model, the fire extinguishing pipeline 7-1 includes a water outlet pipeline 17 and a water inlet pipeline 7; the water inlet pipeline 7 is communicated with the water outlet pipeline 17; the communication method here is diverse. It can be that the water inlet pipeline 7 is directly communicated with the water outlet pipeline 17, or an internal channel can be provided in the fire extinguishing platform 5, the water outlet pipeline 17 and the water inlet pipeline 7 are embedded in the fire extinguishing platform 5, and the water inlet pipeline 7 and the water outlet pipeline 17 are communicated with the internal channel in the fire extinguishing platform 5. Subsequently, the water inlet pipeline 7 is communicated with the water outlet pipeline 17 through the internal channel; such a setting facilitates the flow of the fire extinguishing medium in the fire extinguishing pipeline 7-1.

In addition, in the present utility model, the liquid supply mechanism is mainly arranged at the front bumper 16 and the rear bumper 15 of the vehicle. The setting of the water guide pipe 3 facilitates the communication between the fire extinguishing pipes 7-1 on the fire fighting platform 5 and the corresponding liquid supply mechanism. Generally speaking, it is convenient for the overall layout and installation of the fire extinguishing system on the vehicle.

[0035] Furthermore, in the present utility model, a check valve 13 is provided at one end of the water inlet pipe 7 close to the liquid supply mechanism; such a setting makes the water inlet pipe 7 flow unidirectionally, avoiding the overflow of the fire extinguishing medium from other water inlet pipes 7 when a single water inlet pipe 7 is feeding liquid.

[0036] Furthermore, in the present utility model, a plastic plug is provided on each of the water outlet holes 6; in the present utility model, the plastic plug plays a good sealing and protection role, preventing sundries from entering the water outlet holes 6 and blocking the normal discharge of the fire extinguishing medium from the fire extinguishing pipes 7-1 when not in use.

[0038] An electric vehicle assembly includes a chassis and a battery pack 8 disposed on the chassis; the chassis and the battery pack 8 are spaced apart to form an assembly gap; the new energy fire extinguishing system is provided in the assembly gap between the chassis and the battery pack 8; the fire extinguishing system disclosed in the present utility model can be used in the area between the chassis and the battery pack 8 of the electric vehicle, mainly arranged between the battery of the new energy vehicle and the vehicle body, increasing the fire extinguishing space; when the battery catches fire, by using the reserved fire extinguishing space, through an external water pipe or fire extinguishing foam method, the fire extinguishing material is directly applied to the fire source point; thereby achieving a better fire extinguishing effect, breaking the problem that the current traditional battery and vehicle body are integrated, resulting in the inability to directly extinguish the fire against the fire source; it can improve the fire extinguishing efficiency and reduce the situation of fire spread and more extensive losses to the vehicle.

[0039] Further, in the present utility model, the new energy fire extinguishing system at least includes two liquid supply mechanisms; at least one liquid supply mechanism extends to the position of the front bumper 16 of the vehicle body; at least one liquid supply mechanism extends to the position of the rear bumper 15 of the vehicle body; such a setting enables the front end and the rear end of the whole vehicle to be externally connected to fire fighting equipment, facilitating the connection between the fire fighting equipment and the whole vehicle.

[0041] Specific;

[0042] The working principle of the present utility model is as follows:

[0043] When a spontaneous combustion occurs in the vehicle battery, if the front of the vehicle is convenient for rescue, the fire fighter can open the interface plug 4 inside the front bumper 16, pull out the front fire hydrant interface through the front fire extension hose to a position 5 meters away from the vehicle body, then connect the fire fighting water pipe of the fire truck and open the water valve.

[0044] The fire extinguishing water will enter the front check valve 13 through the front water pipe 3, and quickly fill along the water inlet pipe 7 and the annular water outlet pipe 17. Under the action of water pressure and high temperature, the plastic plug of the fire extinguishing water outlet will be washed open, and the fire extinguishing water will spray on the battery pack along the distributed water outlets to extinguish the fire; achieving the purpose of quickly isolating the battery flame from the vehicle body, reducing the expansion of losses and affecting the surrounding area.

[0045] Similarly;

[0046] When the rear of the vehicle is convenient for connecting to the fire hydrant, the firefighters can open the interface plug cover 4 built into the rear bumper 15, pull out the rear fire hydrant interface 5 meters away from the vehicle body through the rear fire extension hose, then connect it to the fire truck's fire extinguishing water pipe and open the water valve; the fire extinguishing water will pass through the rear water guide pipe 3 and enter the rear check valve 13, and quickly fill along the water inlet pipe 7 and the annular water outlet pipe 17. Under the action of water pressure and high temperature, the plastic plug cover of the fire extinguishing water outlet will be washed away, and the fire extinguishing water will spray on the 8 battery packs along the water outlets distributed on the 5th floor of the fire extinguishing platform.

[0047] Similarly, two fire hydrant connection ports are arranged at the front and rear of the whole vehicle, which is convenient for firefighters to complete the connection from one of the four interfaces according to factors such as the parking position and angle of the vehicle, and then can extinguish the fire on the battery pack at the bottom of the vehicle. In order to prevent the backflow of the fire extinguishing water, check valves 13 are built into all four interfaces to release all the water pressure on the battery surface.

[0048] Through the above design, the present utility model is equivalent to increasing the fire extinguishing space between the battery of the new energy vehicle and the vehicle body; when the battery catches fire, the reserved fire extinguishing space can be utilized to directly apply the fire extinguishing material to the fire source point by means of an external water pipe or fire extinguishing foam. Thus, a better fire extinguishing effect can be achieved, breaking the problem that the traditional integration of the battery and the vehicle body currently leads to the inability to directly extinguish the fire at the fire source. It can improve the fire extinguishing efficiency and reduce the situation of fire spread and more extensive losses to the vehicle.

[0049] Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present utility model, they are all within the protection scope of the present utility model.
