[0002] The electric bicycle is also called "electric bicycle", it is the pure electric motor vehicle that the battery (car battery) provides the electric energy, by the motor (direct current, alternating current, series excitation, he excitation) drive. The service life of the electric bicycle is generally 8 to 12 years, and the service life of the battery is generally 1-4 years (depending on the use and maintenance). The battery will increase the fire risk when aging with the increase of the use time of the electric bicycle, so the electric bicycle needs the fire extinguishing device protection.

DETAILED DESCRIPTION

[0037] Embodiments of the present application will now be described with reference to the accompanying drawings.

[0038] Embodiments

[0039] As shown in the specific embodiments of the present application, Figures 1 to 12 A lifting electric bicycle fire extinguishing device, comprising a water storage tank 3 provided with an opening at the top, the inner side of the water storage tank 3 is provided with a vehicle loading plate 4, and the vehicle loading plate 4 is connected with a lifting mechanism. It also includes a sensing device 5 located on one side of the vehicle loading plate 4, and the sensing device 5 and the lifting mechanism are both electrically connected with a control assembly. The top opening of the water storage tank 3 is flush with the ground.

[0040] The lifting mechanism is connected between the bottom of the vehicle carrying plate 4 and the bottom of the water storage tank 3. The lifting mechanism comprises a first telescopic mechanism 2 transversely mounted on the bottom of the vehicle carrying plate 4, both ends of the first telescopic mechanism 2 being telescopic ends. The lifting mechanism further comprises a pair of support structures, the two support structures being symmetrically arranged at both ends of the first telescopic mechanism 2, one end of each support structure being rotatably connected with one end of the first telescopic mechanism, and the other end of the support structure being rotatably connected with the bottom of the water storage tank 3, the first telescopic mechanism 2 being electrically connected with the control assembly.

[0041] Preferably, the support structure is a second telescopic mechanism, one end of each second telescopic mechanism being rotatably connected with one end of the first telescopic mechanism, and the other end of the second telescopic mechanism being rotatably connected with the bottom of the water storage tank 3. The second telescopic mechanism is electrically connected with the control assembly.

[0042] The lifting mechanism of the present scheme realizes lifting in a manner that the first telescopic mechanism 2 and the second telescopic mechanism cooperate, when the vehicle carrying plate 4 is in a normal state, the second telescopic mechanism is vertically arranged; when the vehicle carrying plate 4 is in a lowered completed state, the second telescopic mechanism is in a state close to horizontal (there is always an included angle between the second telescopic mechanism and the first telescopic mechanism 2, so as to ensure that the two telescopic mechanisms cannot relatively rotate due to being located on the same straight line). Compared with directly using a vertically arranged telescopic structure to realize lifting, the lifting mechanism of the present scheme occupies less space in the retracted state, and can be lowered to a greater height.

[0043] In the present embodiment, the bottom of each vehicle carrying plate 4 is provided with two first telescopic mechanisms 2 arranged side by side, and each first telescopic mechanism 2 is provided with a second telescopic mechanism at both ends.

[0044] The first telescopic mechanism 2 comprises a gear 23, first and second racks 24 and 25 arranged opposite to each other, and the gear 23 is located between the first and second racks 24 and 25 and is engaged with the first and second racks 24 and 25, respectively. The gear 23 is connected with the power output shaft of a driving motor 21, and the driving motor 21 is mounted on the vehicle carrying plate 4. The driving motor 21 drives the gear 23 to rotate forward and backward, thereby driving the first and second racks 24 and 25 to move telescopically relative to the vehicle carrying plate 4.

[0045] The control assembly comprises a first controller 22 electrically connected with the driving motor 21. The vehicle carrying plate 4 is further provided with rack sliding rails 42, the number of which corresponds to the number of racks. Both the first and second racks 24 and 25 are in sliding cooperation with the rack sliding rails 42. One end of each of the first and second racks 24 and 25 is rotatably connected with one end of a second telescopic mechanism.

The control assembly also includes a second controller 15 electrically connected to the hydraulic rod 12. In this embodiment, the four hydraulic support devices 1 are located at the four corners of the vehicle platform 4.

[0047] The vehicle platform 4 is provided with multiple water-permeable holes 41.

The sensing device 5 is installed on the top opening side of the water tank 3, and the control assembly can receive the wireless signal from the sensing device 5 to start or stop the lifting mechanism.

[0050] like Figure 7 As shown in the schematic diagram of the fire extinguishing procedure, when the sensor device 5 detects that the electric bicycle 6 is on fire, the device runs the fire extinguishing procedure. The gear 23 rotates clockwise under the drive of the drive motor 21, the first rack 24 and the second rack 25 retract towards the middle, and the hydraulic rod 12 rotates and extends around the support base 11 under the action of the first rack 24, the second rack 25 and the second controller 15. The vehicle platform 4 slowly descends, and the water inside the water tank 3 gradually covers the vehicle platform 4 through the water permeable hole 41.

[0051] like Figure 8 As shown in the diagram of the completed fire extinguishing procedure, the hydraulic rod 12 has been rotated to near horizontal, the vehicle platform 4 has been lowered to its lowest point, and the water source inside the water tank 3 is able to submerge the burning electric bicycle battery, thus achieving immersion fire extinguishing.
