Problems solved by technology

[0003] The above-mentioned electric balance bikes walk on two wheels. Analyzing its working principle, if it is used as a wheelchair, the stability is relatively poor. Moreover, when the power supply system of the vehicle is insufficient, due to the left and right distribution of the two wheels, when the vehicle crosses obstacles, the vehicle body will lean forward. or backwards, which may cause the operator to fall

Embodiment Construction

[0016] As shown in Figure 1, a self-balancing electric wheelchair with back protection wheels includes a car body 1 with wheels 2 connected to the rotating shafts on both sides and a seat 3 connected to the car body 1. The car body 1 is equipped with a drive system and self-balancing control system, the control switch is installed on the seat 3, in order to make the occupant more comfortable, the angle α between the cushion front of the seat 3 and the horizontal plane is 1.5°~2.5°, the vehicle body 1 front and rear wheel frames 41,42 are also respectively equipped with front and rear wheel frames 41, a pair of front wheels 5 are housed in the front wheel frames 42, and a pair of reclining protection wheels 6 are housed in the rear wheel frames 42.

[0017] The diameter of the front wheel 5 is larger than that of the back protection wheel 6. When driving normally, the front wheel 5 touches the ground and the back protection wheel 6 is suspended in the air. The line angle β is 9...

Description

technical field [0001] The invention relates to a self-balancing electric vehicle, in particular to a self-balancing electric wheelchair with backward protection wheels. Background technique [0002] Self-balancing electric vehicles are good means of transportation in places where cars cannot pass, and many disabled people also choose this type of vehicle as a walking tool. The usual operating principle of existing self-balancing electric vehicles is mainly based on a basic principle called "Dynamic Stabilization", that is, the self-balancing ability of the vehicle itself. The American Segway self-balancing car uses the built-in precision solid-state gyroscope (Solid-State Gyroscopes) to judge the balance state of the body, and calculates the appropriate motor output torque command through the precise and high-speed central microprocessor. Drive the motor to achieve a balanced effect. Suppose we take the vertical axis of the overall center of gravity of the driver standing...
