Embodiment Construction

[0023] like figure 1 As shown, the smart wheelchair is composed of 19 main core mechanical components. The wheelchair neck pillow 1 is positioned and fastened on the wheelchair seat 18 by two cylindrical pins. The wheelchair armrests 2 on both sides are fastened on both sides of the wheelchair seat 18 by bolts. The wheelchair frame 3 is the basic support of the intelligent wheelchair, and the drive battery and drive motor of the wheelchair are all installed on the wheelchair frame 3 . One end of the wheelchair damping spring 4 is connected with the wheelchair frame 3, and the other end is connected with the anti-overturning wheel 5 through a support rod. The anti-seismic and anti-overturning system composed of the anti-overturning wheel 5 and the wheelchair damping spring 4 can effectively prevent the user from overturning while riding the wheelchair, and can also reduce the vibration when the wheelchair runs into bumpy road conditions. The front-end ultrasonic sensor 6, th...
