[0001] This utility model relates to the field of fire extinguishing technology, and in particular to a fire extinguishing robot for the undercarriage of a car. Background Technology

[0002] Currently, the batteries of new energy vehicles are located at the bottom of the car. When a new energy vehicle battery catches fire, it can only be effectively extinguished by spraying fire extinguishing agent from the bottom up through the chassis. Different models have different chassis design heights. Especially for new energy vehicles, with the increase in driving range and battery energy density, it becomes difficult to deal with the battery in a timely and effective manner in an emergency.

[0003] Existing fire-fighting robots applicable to the underside of cars have fixed water outlet points. This prevents the adjustment of the distance between the water outlet point and the fire source to suit different car underside environments, thus affecting fire-fighting efficiency and delaying the best fire-fighting opportunity.

[0004] Therefore, designing a car under-vehicle fire extinguishing robot that can adjust the distance between the water outlet of the fire extinguishing robot and the fire site is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0036] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0037] Example 1

[0038] This embodiment provides a car undercarriage fire extinguishing robot, such as... Figure 1 and Figure 2 As shown, it includes a fire extinguishing box 1 and a wheel assembly 2; the wheel assembly 2 is disposed at the lower part of the fire extinguishing box 1; the wheel assembly 2 includes a frame 21 and a drive assembly 22;

[0039] The drive assembly 22 includes a first motor 221, a first gear 222, and a first rack 223. The first motor 221 is mounted on the vehicle frame 21. The first gear 222 is mounted on the output end of the first motor 221. The first rack 223 is fixed on the inner wall of the fire extinguishing box 1, and the first rack 223 is positioned opposite to the first gear 222. The first motor 221 drives the first gear 222 to rotate, and the first gear 222 drives the first rack 223 to rise or fall, thereby raising or lowering the fire extinguishing box 1 relative to the vehicle frame 21.

[0040] This utility model discloses a car under-vehicle fire extinguishing robot, comprising a fire extinguishing box 1 and a wheel assembly 2. The wheel assembly 2 includes a frame 21 and a drive assembly 22. The first motor 221 in the drive assembly 22 drives the first gear 222 to rotate, and the first gear 222 drives the first rack 223 to rise or fall, thereby raising or lowering the fire extinguishing box 1 relative to the frame 21, changing the height of the upper surface of the fire extinguishing box 1. Based on the chassis height of the new energy vehicle and the fire situation, the distance between the water outlet point on the upper surface of the fire extinguishing box 1 and the fire site is adjusted to extinguish the fire under the car in a timely manner, improving the versatility and operational flexibility of the fire extinguishing robot.

[0041] In this embodiment, the maximum height of the under-vehicle fire extinguishing robot is 120mm, and the minimum height is 70mm. The minimum height of existing domestically produced car chassis is 110mm, and if a fire causes a tire blowout, the chassis height will be lowered to 80mm. The under-vehicle fire extinguishing robot described in this embodiment can ensure smooth entry under the car to carry out fire extinguishing operations.

[0042] In this embodiment, a through hole 11 is provided on the side wall of the fire extinguishing box 1;

[0043] The frame 21 includes a crossbeam 211 and a vertical beam 212; the crossbeam 211 is disposed inside the fire extinguishing box 1, and both ends of the crossbeam 211 pass through the through hole 11 and are located outside the fire extinguishing box 1; the vertical beam 212 is disposed at both ends of the crossbeam 211.

[0044] The fire extinguishing box 1 has a through hole 11 to facilitate the installation and fixation of the crossbeam 211, ensure the stability of the frame 21 during relative movement, and ensure the structural reliability of the fire extinguishing robot during driving and operation.

[0045] In this embodiment, the wheel assembly 2 includes a groove 23, which is disposed on the outer side wall of the fire extinguishing box 1.

[0046] In this embodiment, the wheel assembly 2 further includes a slider 24 disposed on the vertical beam 212, and the slider 24 is disposed opposite to the groove 23.

[0047] When the fire extinguishing box 1 rises or falls relative to the frame 21, the slider 24 rises or falls in the slide groove 23 accordingly. The slide groove 23 provides guidance for the movement of the slider 24, enabling the frame 21 to maintain a stable linear movement during the rising or falling process. This further improves the stability of the relative movement between the wheel assembly 2 and the fire extinguishing box 1, and helps to improve the accuracy of fire extinguishing operations.

[0048] In this embodiment, the wheel assembly 2 further includes a wheel 25 disposed below the slider 24.

[0049] Example 2

[0050] The car undercarriage fire extinguishing robot shown in this embodiment, such as Figures 1 to 4 As shown, it further includes a fire extinguishing component 3 based on embodiment 1. The fire extinguishing component 3 includes a water supply pipe 31 and a water spray valve 32, with the water spray valve 32 disposed on the water supply pipe 31.

[0051] The fire extinguishing box 1 has a water outlet 12 on its upper surface, and the water outlet 12 is arranged opposite to the water spray valve 32.

[0052] A car-under-vehicle fire-fighting robot moves to the area under the car to be extinguished, and water spray valves 32 spray water onto the fire to put it out. Multiple water spray valves 32 are installed, and the water mist sprayed from them can be directed upwards towards the chassis of the new energy vehicle. Figure 4 As shown, the water spray valve 32 includes a first sub-valve 321 and a second sub-valve 322, and the spray angle of both the first sub-valve 321 and the second sub-valve 322 is 60°.

[0053] The water spray valve 32 is retractable, such as... Figure 5 As shown, the sprinkler valve 32 includes a telescopic belt 323. The length of the telescopic belt can be adjusted by water pressure, thereby adjusting the height of the sprinkler valve. Water flowing towards the sprinkler valve applies pressure. When the flow rate is greater than 0.4 L / s, the applied pressure exceeds the elastic limit of the telescopic belt, causing it to extend upwards and raising the height of the sprinkler valve. The sprinkler valve can extend upwards by 10 mm, extending the spray nozzle beyond the upper surface of the fire extinguishing box 1, increasing the spray range. Figure 6 As shown, the telescopic belt 323 of the water spray valve 32 is in the retracted state. Figure 6 Center line A indicates the relative position marker of the spray valve 32 when the telescopic belt 323 is in the retracted state; for example... Figure 7 As shown, the telescopic band 323 of the water spray valve 32 is in the extended state. Figure 7 Center line B indicates the relative position marking of water spray valve 32 when the retractable belt 323 is in the extended state. The water spray valve sprays a fine water mist. This method of spraying fine water mist can not only effectively cool the underside of new energy vehicles, but also save water, thereby effectively improving the fire extinguishing efficiency of water.

[0054] The maximum flow rate of a single water spray valve is 0.6 L / s. The fire-fighting robot has seven water spray valves with a maximum flow rate of 4.2 L / s. Calculations show that it takes 238 seconds, or approximately 4 minutes, to spray one ton of water.

[0055] In this embodiment, the fire extinguishing assembly 3 further includes a second drive motor 33, a second gear 34, and a second rack 35; the second drive motor 33 is disposed inside the fire extinguishing box 1, the second gear 34 is disposed at the output end of the second drive motor 33, and the second rack 35 is disposed in the water supply pipe 31.

[0056] The second drive motor 33 drives the second gear 34 to rotate, the second gear 34 drives the second rack 35 to rise or fall, thereby driving the water pipe 31 to rise or fall.

[0057] By changing the height of the water supply pipe 31 inside the fire extinguishing box 1 and adjusting the height of the water spray valve 32 extending from the water outlet 12 on the fire extinguishing box 1, the distance between the water spray valve 32 and the fire point under the vehicle can be further adjusted to improve fire rescue efficiency. When the fire situation changes, the height of the water spray valve 32 can be adjusted in time so that the water spray valve 32 can be aimed at the fire source more accurately, improving the accuracy and effect of fire extinguishing and adapting to the fire extinguishing needs of different fire intensities and vehicle under-body structures.

[0058] In this embodiment, the car under-vehicle fire extinguishing robot also includes a battery pack module 4, which provides power to the fire extinguishing robot and provides power to the fire extinguishing component 3 and the drive component 22.

[0059] In this embodiment, the water supply pipe 31 further includes an input end 311. The input end 311 is used to connect to an external water source.

[0060] In this embodiment, an opening 13 is provided on the fire extinguishing box 1 at a position corresponding to the input terminal 311.

[0061] When the water supply pipe 31 rises or falls relative to the fire extinguishing box 1, the size of the opening 13 can accommodate the rise or fall of the water supply pipe 31.

[0062] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
