The invention discloses a liftable chassis of an intelligent wheelchair. The liftable chassis comprises castors, a lifting mechanism and a lifting seat, wherein obstacle detection systems are arranged on the castors, the castors comprise a front castor and a rear castor, and the front castor is an AGV (automated guided vehicle) solenoid drive wheel; the lifting mechanism comprises a front multi-stage hydraulic cylinder, a front hydraulic oil tank, a front lifting supporting leg, a rear multi-stage hydraulic cylinder, a rear hydraulic oil tank and a rear lifting supporting leg; the front lifting supporting leg and the rear lifting supporting leg are fixedly connected with the lifting seat; a front oil pump and a front hydraulic distributor are arranged on the front hydraulic oil tank; a rear oil pump and a rear hydraulic distributor are arranged on the rear hydraulic oil tank; a control panel and a power supply are arranged at the bottom of the lifting seat; a central processing unit is arranged on the control panel and electrically connected with the front castor, the obstacle detection systems, the front oil pump, the front hydraulic distributor, the rear oil pump, the rear hydraulic distributor and the power supply. The lifting chassis has the advantages that the structure is simple, the stability is good, and the intelligent degree is higher and the control is more precise due to processing by the central processing unit.
Description
technical field [0001] The invention relates to the field of intelligent wheelchairs, in particular to a chassis capable of lifting and lowering the wheelchair. Background technique [0002] Wheelchair is an important tool for rehabilitation. It is not only a means of transportation for physically disabled and handicapped people, but more importantly, it enables them to perform physical exercises and participate in social activities with the help of wheelchairs. Ordinary wheelchairs are generally composed of four parts: wheelchair frame, wheels, brake device and seat. In real life, different bodies and different use environments have different height requirements for wheelchairs. [0003] Publication number: the Chinese patent document of CN103565594A discloses a kind of wheelchair multi-connecting rod lifting mechanism. The whole mechanism uses a push rod motor, which is transmitted to the three connecting rod folding mechanisms at the same time to ensure that the lifting...
