The device can enter the bottom of the new energy vehicle through the rectangular frames and the crossbeam pipes to cool the battery at the bottom, preventing it from burning out. The remote control drive structure allows for remote control entry into the bottom of the vehicle and provides fixation to prevent the device's position from being altered by the impact of water flow.

Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing device technology, specifically a fire extinguishing device for the chassis of a new energy vehicle. Background Technology

[0002] With the development of society, more and more new energy vehicles are appearing on the road. For new energy vehicles, the stability of the battery is particularly important. During the operation of new energy vehicles, if the battery is damaged by external forces, it is prone to high temperature and combustion.

[0003] Among existing fire extinguishing devices, especially in vehicles, the most common is the fire extinguisher placed inside the vehicle. However, the batteries of existing new energy vehicles are all fixedly installed at the bottom of the vehicle. Due to the low chassis of the vehicle, common fire extinguishers cannot reach the bottom of the vehicle, resulting in poor fire extinguishing and cooling effects. Although a fire extinguishing and cooling device for automobile chassis and its usage method disclosed in CN118718295A can reach the bottom of the vehicle for cooling, it has been found in actual use that the high temperature can easily burn out the water hose, and the impact force of the water flow from the external water pump entering the pipe can easily cause the whole device to move, requiring manual fixation, which poses a certain danger. Utility Model Content

[0004] The purpose of this invention is to provide a fire extinguishing device for the chassis of new energy vehicles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire extinguishing device for a new energy vehicle chassis, including a main pipe, a rectangular frame fixedly threaded to one side of the main pipe, a crossbeam pipe threaded between the rectangular frames, a number of universal wheels evenly arranged below the rectangular frames, a number of nozzles evenly arranged on the upward surface of the rectangular frames and the crossbeam pipe, and a remote control drive structure snapped onto the main pipe.

[0006] Preferably, the remote control drive structure includes an elastic retaining ring, with a housing fixedly connected below the elastic retaining ring. The housing contains a battery, a control circuit, a drive motor, and an electric telescopic rod. The output end of the electric telescopic rod is fixedly connected to an inclined plate, and the output end of the drive motor is fixedly connected to a drive wheel.

[0007] Preferably, the rectangular frame is composed of several pipes connected together, and both the rectangular frame and the crossbeam pipes are made of metal.

[0008] Preferably, the control circuit is equipped with a wireless transmission module, which is electrically connected to the mobile terminal.

[0009] Preferably, the outer surface of the inclined plate has a plurality of protrusions evenly distributed.

[0010] Preferably, a push rod is fixedly connected to one end of the main pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the rectangular frame and crossbeam pipe can enter the bottom of the new energy vehicle to cool down the battery at the bottom, and it is not easy to burn out. The remote control drive structure can remotely control the entry into the bottom of the vehicle and fix it to prevent the water flow impact force from changing the position of the device.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0016] Please refer to 1-2. One embodiment of this utility model is a fire extinguishing device for a new energy vehicle chassis, including a main pipe 1. A rectangular frame 2 is fixedly threaded to one side of the main pipe 1. A crossbeam pipe 3 is threaded between the rectangular frames 2. Several universal wheels 4 are evenly arranged below the rectangular frames 2. Several nozzles 5 are evenly arranged on the upward surface of the rectangular frames 2 and the crossbeam pipe 3. A remote control drive structure 6 is snapped onto the main pipe 1. The remote control drive structure 6 is connected to the main pipe 1. The rectangular frames 2 are moved to the underside of the new energy vehicle chassis by the remote control drive structure 6. A water pump is fixedly connected to one side of the main pipe 1 by a water hose. The water pump delivers water to the rectangular frames 2 and the crossbeam pipe 3. The nozzles 5 are used to cool the battery of the new energy vehicle chassis.

[0017] The remote control drive structure 6 includes an elastic retaining ring 61, with a housing 62 fixedly connected below the elastic retaining ring 61. The housing 62 contains a battery, a control circuit, a drive motor, and an electric telescopic rod. The output end of the electric telescopic rod is fixedly connected to an inclined plate 64, and the output end of the drive motor is fixedly connected to a drive wheel 63. The main pipe 1 is fixedly connected using the elastic retaining ring 61. When not in use, the remote control drive structure 6 can be removed for storage and charging. After the rectangular frame 2 reaches the bottom of the vehicle, the electric telescopic rod is controlled to push the inclined plate 64 to move, so that the inclined plates 64 on both sides contact the ground. At this time, the inclined plates 64 on both sides and the drive wheel 63 form a triangular stable structure, which fixes the position of the main pipe 1.

[0018] The rectangular frame 2 is composed of several pipes connected together. Both the rectangular frame 2 and the crossbeam pipes 3 are made of metal materials, which are resistant to high temperatures and not easily burned. The control circuit is equipped with a wireless transmission module, which connects to the mobile terminal via electrical signals for easy remote control. Several protrusions are evenly distributed on the outer surface of the inclined plate 64 to increase the friction with the ground.

[0019] A push rod is fixedly connected to one end of the main pipe 1, which facilitates manual movement of the entire structure.

[0020] Working principle: In use, the main pipe 1 is fixedly connected by the elastic retaining ring 61. Then, the rectangular frame 2 is aligned with the chassis of the new energy vehicle. The drive motor is started by the mobile terminal, which drives the drive wheel 63 to move forward and enter the chassis of the new energy vehicle. Then, the electric telescopic rod is started to push the inclined plate 64 to move, so that the inclined plates 64 on the left and right sides contact the ground and fix the rectangular frame 2. As the water pump on one side of the main pipe 1 is turned on, the water flow impacts the rectangular frame 2 and the crossbeam pipe 3, and cools and extinguishes the fire on the vehicle chassis through the nozzle 5.
