Scooter for physically challenged

Abstract

The invention relates to the field of electric bicycles and discloses a scooter for the physically challenged. The scooter for the physically challenged comprises a scooter frame and a saddle fixed tothe scooter frame. The scooter frame is provided with two rear wheels serving as drive wheels and a front wheel serving as a driven wheel. The front wheel is installed on the scooter frame through awheel fork, and a steering handlebar is installed at the upper end of the wheel fork; a power system for providing drive force for the rear wheels is arranged in the position, below the saddle, of thescooter frame; the power system comprises a motor, a storage battery and a transmission device, and the transmission device is connected with the power input ends of the rear wheels; and the power system further comprises a range extension device for providing electric energy for the motor to achieve range extension, the range extension device comprises a power generator and an extended-range engine, and the power generator is electrically connected with the storage battery and the motor. By means of the scooter for the physically challenged, the endurance mileage can be effectively improved,the efficiency of converting electric energy to mechanical energy is improved, besides, the requirement of high-power conditions can be met, and thus the working requirements of different pavements can be met.

Description

technical field [0001] The invention relates to the field of electric vehicles, and specifically discloses a scooter for disabled people. Background technique [0002] Disabled people are the weakest group among the socially disadvantaged groups. Their physical disabilities limit their mobility. Disabled people face many difficulties in various fields of life. However, the limitations of material conditions and the lack of awareness from the outside world make it impossible for disabled people to have The right to participate in all areas of society and share life equally with ordinary people, and the overall quality and level of life are inferior to those of healthy people. A scooter for the disabled is a vehicle specially used for the disabled. It generally includes a frame and a seat fixed on the frame. The frame is provided with two rear wheels as driving wheels and a front wheel as a driven wheel. The front wheel is installed on the frame through the wheel fork, the up...

Problems solved by technology

A scooter for the disabled is a vehicle specially used for the disabled. It generally includes a frame and a seat fixed on the frame. The frame is provided with two rear wheels as driving wheels and a front wheel as a driven wheel. The front wheel is installed on the frame through the wheel fork, the upper end of the wheel fork is equipped with a steering handle, and the frame under the seat is provided with a power system for providing driving force for the rear wheel. The output motor, the battery used to supply power to the motor and the transmission device that cooperates with the power output end of the motor, the transmission device is connected to the power input end of the rear wheel; the motor generally directly drives the rear wheel through gear reduction, in order to improve its driving Speed, gradeability and torque usually increase the power of the motor at any cost, which causes changes in driving conditions, and the motor cannot effectively work within the optimal efficiency range, resulting in low efficiency of electrical energy conversion to mechanical energy and short cruising range of the vehicle , can no longer meet the needs of use
