| titleOfInvention | Wheelchair capable of crossing obstacle |
| abstract | The invention relates to a wheelchair capable of crossing obstacles, which comprises a chair main body, wherein the chair main body is formed by fixing a backrest, a chair seat and handrails, a main rod is transversely fixed below the chair seat and is connected with a driving wheel swing arm a, a driving wheel swing arm d, a driving wheel swing arm b and a driving wheel swing arm c, the driving wheel a and the driving wheel b are fixed below the front driving swing arm, the driving wheel c and the driving wheel d are fixed below the rear driving swing arm, an electric push rod a and an electric push rod b are vertically hinged to the front and the rear of the chair seat respectively and are hinged to a front swing arm group and a rear swing arm group respectively, an auxiliary wheel support frame and an auxiliary wheel are further connected below the main rod, and the driving wheel and the electric push rod are connected with. The four-wheel hub motor drives the four-wheel hub motor to advance, and the steering adopts a differential steering mode. When the obstacle is passed through, the two groups of driving wheels driven by the electric push rod and the auxiliary wheel in the middle alternatively act to realize the obstacle crossing function. |
