[0012] Beneficial Effects

[0013] The utility model provides an amphibious driving assembly of an electric vehicle for rescue.

[0014] Beneficial effects:

[0015] 1. The amphibious driving assembly of an electric vehicle for rescue is provided with a moving mechanism and a driving mechanism. When in use, the rotating shafts of the two wheels of the electric vehicle are installed on two fixed frames, and the driving gear is connected to the motor transmission at the rear side of the electric vehicle through a chain. At this time, the two moving front wheels and the two moving rear wheels can well support the two hulls, and the motor at the rear side of the electric vehicle drives the connecting rotating rod to rotate through the driving gear, and the connecting rotating rod drives the two moving rear wheels to rotate synchronously, so that the electric vehicle can walk well on land. When the electric vehicle is on water, the buoyancy formed by the two hulls can drive the electric vehicle to float on the water surface, and the connecting rotating rod is driven to rotate by the motor at the rear side of the electric vehicle, and the connecting rotating rod drives the water-driven propeller blades at the rear side of the water rotating shaft to rotate through the active steering gear and the passive steering gear, thereby forming thrust in the water, so that the electric vehicle can travel on water. The above operation is simple and convenient, so that the electric vehicle has the function of amphibious driving, so that users can also carry out self-rescue when floods come, thereby improving the applicability of the equipment.

[0016] 2. The amphibious driving component of an electric vehicle for rescue is provided with a steering mechanism. When the user operates the front wheel of the electric vehicle to steer, the front wheel of the electric vehicle drives the front wheel fixing frame to rotate to support the rotating shaft rod. The supporting rotating shaft rod drives the active steering rod to rotate and drives the steering gear connecting rod to move. The steering gear connecting rod drives the two passive steering rods to steer synchronously through two passive steering rods and two front wheel steering gears, so that the equipment can travel more smoothly on land. In addition, since a water-dividing steering gear is provided at the bottom end of the active steering rod, the water-dividing steering gear can steer with the front wheel of the vehicle, thereby realizing the function of the equipment being able to steer in water. The above operation is simple and convenient, the structure is reasonable and compact, and the applicability of the equipment is improved.

[0017] 3. The amphibious driving component of an electric vehicle for rescue is provided with a locking nut. When the equipment is traveling on land, the locking nut can be rotated to drive the active steering gear to move to the left and disengage the passive steering gear, so that the connecting rotating rod will not drive the active steering gear and the passive steering gear to drive the water-driven propeller blades on the water-driven shaft to rotate, thereby avoiding safety problems caused by the rotation of the water-driven propeller blades, making the equipment safer to use.
