Disclosed is a novel multifunctional wheelchair bed. A bed body and a wheelchair are combined to form the novel multifunctional wheelchair bed, and the bed body comprises a bed frame, bed plates, roller struts and electric push rods. The bed plates comprise seven plates which include side plates and a top plate and form a door-shaped structure, the wheelchair comprises a base, front wheels, rear wheels, a motor, a battery, a wheelchair backrest plate, a seat plate, a shank plate, a pedal plate, base electric push rods, wheelchair backrest electric push rods, an arc-shaped connecting rod, a wheelchair seat electric push rod, a left armrest, a right armrest and a control portion, the control portion comprises an operating lever and a button which are respectively arranged on the left armrest and the right armrest, assembling round rods of the wheelchair rectangular bed plates are respectively inserted into assembling round tubes of the seven plates, which form the door-shaped structure,of the bed body, and then the wheelchair and the bed body can be integrally combined to form a total bed surface. The novel multifunctional wheelchair bed has the advantages that the wheelchair stands by means of driving the electric push rods, the wheelchair with the standing function is combined with the bed body, a patient or an old person can independently control and complete combination andseparation of the wheelchair and the bed body, and functions of the wheelchair and functions of the bed body can be switched.

Omni-directional intelligent electric wheel chair

The invention discloses an omni-directional intelligent electric wheel chair, which comprises a chassis frame and a seat, wherein the two sides below the chassis frame are respectively hinged with an actuating arm of which the left and the right correspond; the actuating arm is connected with Mecanum wheels which can be used for forming a pair of front wheels and a pair of rear wheels; the two sides below the seat, the front part of the seat and the upper parts of the front wheels are respectively provided with an ultrasonic sensor; the outer sides of the Mecanum wheels are respectively provided with an infrared sensor; a handle of the seat is provided with a control box and an operating handle; the actuating arm is also provided with a drive control board; and a drive control board circuit is connected with a digital signal processor (DSP). Compared with the conventional two-wheeled rear-drive electric wheel chair, the omni-directional intelligent electric wheel chair provided by the invention has omni-directional moving abilities, such as lateral direction, slant direction and the like, and has larger movement flexibility; and environment around the wheel chair can be detected through the ultrasonic sensor and the infrared sensor, so as to provide a rider with information of a barrier which can hinder the wheel chair to move, realize that the rider can automatically avoid the barrier when driving the wheel chair or can brake the wheel chair, improve use safety of the wheel chair.

Amphibious recreational vehicle

An amphibious recreational vehicle (motorhome, trailer, SUV, and the like) of conventional RV height, width, and length restricted dimensions necessary to travel on highways and roads, and which upon entering the water, the bottom of the vehicle expands outwardly and upwardly to form a fast planing, wide-beam, ground effects cathedral type double-tunnel hull. The hull makes use of a dynamic air cushion to augment the planing of the hulls, owing to the ground effect created by compression of the ram air stream (and water vapor) rushing through the two tapered tunnels separating the three hulls. The wheels of the vehicle are simultaneously raised out of the water to eliminate parasite drag. The resultant hull is substantially wider than the cabin, providing substantial ocean-going stability for the craft. The folded elements incorporated within the cabin rooftop, raise upward to form a traditional yacht flying bridge, complete with a windshield, steering station, seating, mast, and safety rails. The resultant watercraft closely approximates the off-shore speed, seaworthiness, performance, stability, cabin space, main deck space, and elevated flying bridge deck attributes of conventional yachts. And when on land, the craft is a fully functioning traditional recreational vehicle suited for fast highway travel, driving about towns, staying in RV parks, and camping in the wilderness. This amphibious recreational vehicle is an interrelated component divided from the inventor's previous Comprehensive Vehicle Construction And Hybrid Electric Drive System application.
