Embodiment 1

[0045] figure 2 It is a structural schematic diagram of the wheeled stair-climbing wheelchair provided in this embodiment. As shown in the figure, the wheeled stair climbing wheelchair includes a seat 1 and a driving device 5 . The front planetary gear 3 and the rear planetary gear 4 are respectively arranged on both sides of the driving device 5 , and the front planetary gear 3 and / or the rear planetary gear 4 are driven to move by the driving device 5 . The front planetary wheel 3 and the rear planetary wheel 4 on both sides of the driving device 5 are all connected with the seat 1 through the anti-parallelogram adjustment mechanism 6. When the wheelchair climbs stairs, the center of gravity of the seat is adjusted through the anti-parallelogram adjustment mechanism 6.

[0046] Wherein, the anti-parallelogram adjustment mechanism 6 includes an anti-parallelogram structure formed by hinge connection of the first balance bar 61, the second balance bar 62, the third balance b...

Embodiment 2

[0056] The basic structure of the wheeled stair climbing wheelchair provided by this embodiment is the same as that of Embodiment 1, including a seat and a driving device. Both sides of the driving device are respectively provided with a front planetary wheel and a rear planetary wheel. The front and rear planetary wheels on both sides of the driving device are connected with the seat through the anti-parallelogram adjustment mechanism, and when the wheelchair climbs stairs, the center of gravity of the seat is adjusted through the anti-parallelogram adjustment mechanism.

[0057] The difference from Embodiment 1 is that the first balance bar of this embodiment is directly arranged on the seat, thus saving the first connecting rod and the second connecting rod, and the second balancing rod and the first balancing rod are in the The first connection point is hinged, the third balance bar and the first balance bar are hinged at the second connection point, and the telescopic dev...

Abstract

The invention discloses a wheel-type stair-climbing wheelchair designed for solving the problems of complex structures, poor safety and the like of existing stair-climbing wheelchairs. The wheel-type stair-climbing wheelchair comprises a seat, a driving device and a transmission mechanism connected with the driving device, wherein front and back planet wheels are arranged on two sides of the transmission mechanism respectively, and the front and back planet wheels on two sides of the transmission mechanism are connected with the seat through an inverse parallelogram adjusting mechanism; and when the wheelchair climbs stairs, the angle of the seat is adjusted by the inverse parallelogram adjusting mechanism. According to the wheel-type stair-climbing wheelchair, during stair climbing, the angle of the seat can be adjusted by the inverse parallelogram adjusting mechanism, the center-of-gravity position of a user can be further adjusted, the balance of the user is guaranteed, and the safety of the wheel-type stair-climbing wheelchair during stair climbing is improved; in addition, the inverse parallelogram adjusting mechanism is simple and reliable in structure, so that the production cost of the wheel-type stair-climbing wheelchair is reduced greatly.

Description

technical field [0001] The invention relates to a wheeled wheelchair for climbing stairs. Background technique [0002] With the advent of the 21st century, our country has entered an aging society. Now our country's elderly population has reached 132 million, and it continues to grow at an average annual rate of 3.30%. In addition, there are 60 million people with various disabilities in our country. The existence of people and disabled people has made the problem of helping the elderly and the disabled increasingly a major social problem. In cities, stairs are the most common obstacle in man-made environments and one of the most difficult to overcome. With the advent and development of service robots, the quality of life of the elderly and disabled has been effectively improved, which will be conducive to the stable development of our society. The stair-climbing electric wheelchair is a kind of service robot. It is an indispensable rehabilitation and walking tool for the...
