Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Depend on Figure 1 to Figure 2 Provided is a fire extinguishing and cooling device for a new energy vehicle, comprising a spray rack 1, a supporting rack 2, a window breaking hammer 3, an adjusting mechanism and a driving mechanism.

[0033] First, the spray rack 1 includes a base frame 11 , two side frames 12 , a plurality of spray holes, a connecting pipe 13 , a push handle frame 14 , a handle 15 and a universal wheel 7 .

[0034] Specifically, the two side frames 12 are respectively installed on both sides of the base frame 11, the connecting pipe 13 is arranged at the front end of the base frame 11, and a plurality of spray holes are respectively opened at the top of the base frame 11 and the inner sides of the two side frames 12. The push handle frame 14 is rotatably installed in the middle of the front end of the base frame 11, and the handle 15 is arranged on the side of the push handle frame 14 away from the base frame 11. There are six universal wheels 7, and the six universal wheels 7 are respectively installed at the front and rear ends of the bottom of the base frame 11 and the two side frames 12. More specifically, the base frame 11, the two side frames 12 and the connecting pipe 13 are all made of pipes, and the base frame 11, the two side frames 12 and the connecting pipe 13 are interconnected. The connecting pipe 13 is used to connect an external water source or a foam device; and the handle 15 and the push handle frame 14 facilitate pushing the spray frame 1 to the bottom of the car.

[0035] More specifically, holding the handle 15, the bottom frame 11 is pushed under the chassis of the car through the push handle frame 14, and the two side frames 12 are located on both sides of the car; the external water source enters the bottom frame 11 and the two side frames 12 through the connecting pipe 13, and then sprays water or foam on the car through the spray hole.

[0036] Depend on Figure 3 to Figure 4 It is given that there are four supporting frames 2 and window-breaking hammers 3, and two adjusting mechanisms and driving mechanisms are provided, wherein two supporting frames 2, two window-breaking hammers 3, an adjusting mechanism and a driving mechanism mutually constitute a group of window-breaking structures, and the window-breaking structure is used to break the windows of automobiles. The following is a detailed description of the group of window-breaking structures:

[0037] Specifically, two supporting frames 2 are slidably installed on the top of the side frame 12, and two window breaking hammers 3 are rotatably installed on one side of the two supporting frames 2 respectively. A conical structure is provided on the side of the window breaking hammer 3 away from the supporting frame 2. The setting of the conical structure facilitates better breaking of the car window glass.

[0038] Secondly, the adjusting mechanism is installed on one side of the side frame 12, and the adjusting mechanism cooperates with the two supporting frames 2. Specifically, the adjusting mechanism includes two fixing frames 4, two cylinders 8 and limit members. More specifically, the two fixing frames 4 are respectively installed at the front and rear ends of one side of the spray frame 1, and the two cylinders 8 are respectively installed on one side of the two fixing frames 4, and the output ends of the two cylinders 8 are respectively connected to one side of the two supporting frames 2. More specifically, the cylinder 8 moves against the supporting frame 2, and the window breaking hammer 3 moves with the supporting frame 2, thereby adjusting the positions of the two window breaking hammers 3 so that the two window breaking hammers 3 correspond to the two windows on one side of the car.

[0039] Then, the limiting member is a limiting rod 5, which is installed between the two fixed frames 4. A limiting slot 51 is opened on one side of the supporting frame 2. The limiting rod 5 is slidably installed in the limiting slot 51. The limiting rod 5 and the limiting slot 51 cooperate to limit the supporting frame 2 to avoid rotational deviation during the position adjustment process and ensure stability.

[0040] Depend on Figures 4 to 5 Finally, the driving mechanism is installed between the two fixing frames 4, and the driving mechanism cooperates with the two window-breaking hammers 3. The driving mechanism is used to drive the window-breaking hammers 3 to rotate, and then the car windows are knocked by gravity to break the car windows.

[0041] Specifically, the driving mechanism includes a rotating rod 6, a rod hole 31, two positioning grooves 61, two positioning blocks 32 and a motor 62. More specifically, the two sides of the rotating rod 6 are respectively rotatably installed on one side of the two fixed frames 4. The rod hole 31 is opened on one side of the window breaking hammer 3. The two window breaking hammers 3 are slidably installed on the outside of the rotating rod 6 through the rod hole 31. The two positioning grooves 61 are opened on the outer wall of the rotating rod 6. The two positioning blocks 32 are arranged on the inner wall of the rod hole 31. The two positioning blocks 32 are slidably installed in the two positioning grooves 61. The motor 62 is installed on one side of one of the fixed frames 4, and the output end of the motor 62 is connected to the rotating rod 6. The supporting frame 2 is slidably installed on the periphery of the rotating rod 6. The motor 62 adopts a waterproof motor, and a protective shell is also installed on the outside of the motor 62, and the protective shell is installed on the fixed frame 4.

[0042] More specifically, the motor 62 drives the rotating rod 6 to rotate, and the window breaking hammer 3 rotates along with the rotating rod 6 through the cooperation of the positioning block 32 and the positioning groove 61, and then hits the car window during rotation. Moreover, the window breaking hammer 3 can slide on the rotating rod 6 through the cooperation of the positioning block 32 and the positioning groove 61, and when the supporting frame 2 slides, it will push the window breaking hammer 3 to move together.

[0043] The beneficial effects obtained by the spray rack 1, the supporting frame 2, the window-breaking hammer 3, the adjusting mechanism and the driving mechanism are as follows: the rotating rod 6 is driven to rotate by the motor 62, and the window-breaking hammer 3 rotates at a high speed following the rotating rod 6 to break the car windows, so that the spray rack 1 can spray water or foam into the cab, so as to better achieve fire extinguishing and cooling. At the same time, the cylinder 8 can move against the supporting frame 2 to adjust the position of the window-breaking hammer 3, and then break the windows of cars of different models, thereby improving the fire extinguishing and cooling effect and increasing the efficiency of fire extinguishing and cooling.

[0044] When the utility model is used, the handle 15 is held, and the base frame 11 is pushed under the chassis of the car through the push handle frame 14, while the two side frames 12 are located on both sides of the car; then, the cylinder 8 moves against the carrier frame 2, and the window-breaking hammer 3 moves with the carrier frame 2, and then the position of the window-breaking hammer 3 is adjusted so that the window-breaking hammer 3 corresponds to the window of the car; secondly, the motor 62 drives the rotating rod 6 to rotate, and the window-breaking hammer 3 rotates with the rotating rod 6 through the cooperation of the positioning block 32 and the positioning groove 61, and then hits the car window during rotation to break the car window glass, and finally, the external water source or foam enters the base frame 11 and the two side frames 12 through the connecting pipe 13, and then sprays water or foam on the car through the spray hole to extinguish the fire and cool it down.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
