TL;DR: In this article, the utility model provides a trolley structure with the stair-climbing function, which can be used directly used for common stairs without the reconstruction of the stairs, and the trolley is applicable to common families.
Abstract: The utility model provides a trolley structure with the stair-climbing function, which is a trolley structure directly used for common stairs. The reconstruction of the stairs is not needed, and the trolley is applicable to common families; firstly, the trolley adopts the lever principle to enable the user to stably and vertically lift the trolley through the pedaling way; when the bottom of the trolley is lifted to be in the same height with the adjacent step, then a slide rail is arranged to enable the user to transversely push the trolley to the adjacent step, so as to finish the stair climbing movement; thereby, the user can move the trolley to go upstairs easily and conveniently.

TL;DR: In this article, a multifunctional power-driven stair-climbing trolley capable of moving freely in a narrow space is described, which is used for solving problems that a similar product sways forward and backward when in step movement with a large span and is not safe, the similar product is difficult to move in the narrow space, and the similar products can not integrate functions of stair climbing, walking assistance and push walking on one and is few in function.
Abstract: The utility model provides a multifunctional power-driven stair-climbing trolley capable of moving freely in a narrow space, and relates to medical machinery. The multifunctional power-driven stair-climbing trolley capable of moving freely in the narrow space is used for solving problems that a similar product sways forward and backward when in step movement with a large span and is not safe, the similar product is difficult to move in the narrow space and is not practical, and the similar product can not integrate functions of stair climbing, walking assistance and push walking on one and is few in function. The multifunctional power-driven stair-climbing trolley capable of moving freely in the narrow space mainly comprises a trolley frame, handles, crawler belts, waling wheels and a sliding disc and is characterized in that the lengthened crawler belts are installed on the trolley frame so as to solve safety problems, the sliding disc is installed between the two crawler belts, and a lifting function of the sliding disc enables the crawler belts and the walking wheels to be off the land or on the land. When the sliding disc is in a supporting state, the trolley body can turn and move easily in the narrow space so as to solve practical problems. The trolley is enabled to integrate the functions of stair climbing, walking assistance and push walking on one by controlling different relative heights among the sliding disc, the crawler belts and the walking wheels, so the problem of few function is solved. The trolley is mainly used for the old, the weak, the sick and the disabled to go upstairs or downstairs and to have outdoor activities.

TL;DR: In this paper, an electric stair climbing wheelchair is described, which consists of a frame, armrests, a driving wheel, an auxiliary wheel, a steering wheel controller, and a shaft sleeve.
Abstract: The invention relates to an electric stair climbing wheelchair. The electric stair climbing wheelchair comprises a frame, armrests, a driving wheel, a driving motor, a steering wheel and a steering wheel controller. A stair climbing driving mechanism comprises a tooth ring, a telescopic tooth electric push rod, telescopic teeth, a hub connecting flange, an eccentric circle, a limiting plate and a shaft sleeve. The tooth ring is installed on the inner side of a hub of the driving wheel through a connecting angle. Telescopic holes are machined in the tooth ring and evenly distributed in the tooth ring, and the telescopic teeth are installed in the telescopic holes of the tooth ring. The eccentric circle is installed on a motor shaft of the driving motor and limited by the limiting plate and the shaft sleeve. A telescopic auxiliary wheel mechanism comprises an auxiliary wheel carrier, a shear type telescopic frame, an electric push rod, a lower guide rod, an auxiliary wheel, an upper guide rod and an auxiliary wheel. The driving wheel can better exert climbing driving force through the telescopic teeth to drive the stair climbing wheelchair to finish stair climbing operation, the electric wheelchair has the upstairs going, downstairs going and normal ride-instead-of-walk driving functions, the problem that old people or people unable to move freely drive the wheelchair and go upstairs and downstairs alone is solved, and the use performance and safety of the electric stair climbing wheelchair are improved.

TL;DR: In this article, a self-help electrically-powered wheelchair capable of going up and down stairs is described, which consists of a rear wheel, a contracting brake rotary shaft, a first stair climbing supporting rod, a second stair climbing support rod and a front fork.
Abstract: The invention relates to a self-help electrically-powered wheelchair capable of going up and down stairs, which comprises a rear wheel, a contracting brake rotary shaft, a first stair climbing supporting rod, a second stair climbing supporting rod, a front fork, a front wheel, a frame, a main motor, a driving gear, a storage battery, a reversing shifting fork shaft, a transmission bevel gear, a rear shaft, a driven gear, a seat supporting shaft sleeve, a lifting turbine shaft, a seat, a stair-up-going supporting rod shaft, a universal wheel, a handlebar, a wheelchair front wheel lifting regulation device, a front wheel distance expansion regulation device, a seat lifting regulation device and a seat pitch regulation device. By means of the technical scheme, the self-help electrically-powered wheelchair capable of going up and down the stairs has the advantages of being simple in structure and light in body. The self-help electrically-powered wheelchair can not only conveniently go up and down the stairs but also conveniently run on the road. By means of the self-help electrically-powered wheelchair, disabled persons can go up and down the stairs, go out, travel and go shopping like able-bodied persons without help of external force, thereby solving difficulties of inconvenient out-going.

TL;DR: In this paper, a flexible power wheel set mechanism for climbing stairs is proposed, which consists of a machine body, a plurality of groups of flexible damping power wheel sets and a chain mechanism, where the machine body is fixedly connected with a rack of the wheel chair and is provided with a turnup front part.
Abstract: The utility model relates to a flexible power wheel set mechanism of a wheel chair for climbing stairs, which belongs to a stair climbing traveling gear of a special transport machine or a living facility for the disabled. The flexible power wheel set mechanism comprises a machine body, a plurality of groups of flexible damping power wheel sets and a chain mechanism, wherein the machine body is fixedly connected with a rack of the wheel chair and is provided with a turnup front part, the plurality of groups of flexible damping power wheel sets are respectively arranged at the two sides of the lower end of the machine body, the chain mechanism is used for supplying power to the wheel set mechanism, and the chain mechanism is connected with a power mechanism of the wheel chair. Each flexible damping power wheel set comprises a V-shaped damping mechanism, four small power wheels, two pieces of bearing pedestal connecting plates, a small wheel shaft, a load-bearing shaft and a grooved pulley, wherein the four small power wheels are pairwise coaxial, and the two pieces of bearing pedestal connecting plates are connected by an upper reinforcing plate and a lower reinforcing plate. The small wheels of the flexible power wheel set mechanism can be fully assembled to the stairs so as to achieve a larger contact area, so that the wheel chair has higher reliability and can climb the stairs more smoothly, and the insufficient frictional force of a crawler mechanism for climbing the stairs and the influence on the comfortableness of a user by the overlarge vibration of planet wheels can be effectively avoided. The flexible power wheel set mechanism can be effectively applied to a chassis of various types of wheel chairs.
