Embodiment 1

[0028] see Figure 1~Figure 4 , the medical stair climbing machine includes a leg mechanism (2), a wheel mechanism (3) and a seat (4). It is characterized in that: the leg mechanism (2) is connected with the wheel mechanism (3) and the seat (4), which can prevent rollover when walking on flat ground, and can ensure that the wheelchair stops automatically at the edge of the stairs to prevent slipping during the process of climbing stairs.

Embodiment 2

[0029] Embodiment 2: This example is basically the same as Example 1, and the special features are as follows:

[0030] The leg mechanism (2) includes a support frame (201), two supports (202), an eccentric mechanism (203), a photoelectric sensor (204), a support leg rod (205), a belt transmission mechanism (206), and a shaft ( 207), Coupling 2 (208), Gearbox (209), Coupling 1 (210) and Motor (211). Each component of the leg mechanism (2) is fixed on the support frame (201), and is connected with the seat (4) through the support (202); the leg mechanism (2) is driven by the motor (211), and passes through the coupling 1 (210) is connected with the reduction box (209), and the reduction box (209) transmits the power to the belt transmission mechanism (206) through the coupling 2 (208), thereby controlling the rotation of the shaft (207), the central shaft (207 ) controls the movement of the eccentric mechanism (203), by driving the supporting leg rod (205) to swing up and down...

Embodiment 3

[0035] This preferred embodiment is: see figure 1 , The medical stair climbing machine (1) is mainly divided into a leg mechanism (2), a wheel mechanism (3), and a seat (4). see figure 2 , each component of the leg mechanism (2) of the medical stair climbing machine (1) is fixed on the support frame (201), and is connected with the seat (4) through two supports (202). The leg mechanism (2) is driven by the motor (211), connected with the reduction box (209) through the coupling 1 (210), and the reduction box (209) transmits the power to the belt transmission mechanism through the coupling 2 (208) (206), so as to control the rotational movement of the shaft (207), and the central shaft (207) controls the movement of the eccentric mechanism (203), and by driving the supporting leg rod (205) to swing up and down, the climbing action of the wheelchair is achieved. At the same time, in order to prevent the wheelchair from turning over due to the interference between the leg mech...

Abstract

The invention discloses a medical stair-climbing machine. The medical stair-climbing machine is mainly divided into three main parts including a leg mechanism, wheel mechanisms and a seat. Supporting legs in the leg mechanism are devices which conduct extension or shortening motion through a crank slide block mechanism, and when the medical stair-climbing machine walks on the flat ground, rollover can be prevented. In a stair climbing process, the security problem of a wheelchair needs to be comprehensively considered, it is guaranteed that the wheelchair is automatically stopped at the edge of the stairs, the device is prevented from slipping, and therefore a self-locking device is installed on vehicle wheels. To prevent the situation that the medical stair-climbing machine misses the step, a photoelectric sensor for measuring the distance is installed on a wheel supporting wheel, and the photoelectric sensor is used for measuring the distance between the supporting legs and the stairs. The seat is designed according to ergonomics, is safe and comfortable, and can reduce fatigue and pressure. Regarding the style, the wheelchair body is made from stainless steel and aluminum alloy, can be unfolded or folded, is light, easy to store and moderate in price, and is thus applicable to ordinary family.

Description

technical field [0001] The invention relates to a medical stair climbing machine, which belongs to the fields of engineering technology and medical rehabilitation. Background technique [0002] In recent years, with the improvement of the quality of life and the concept of eugenics, the age group in China will gradually show an aging trend. On the other hand, the disabled still occupy a large proportion in China. At the same time, many public facilities in our country are still not perfect. In most cities, such as overpasses, old-fashioned housing and other living places, there are only stairs for pedestrians and residents, and there is a lack of elevators for ordinary wheelchairs. This brings many problems to the lives of disabled people. Inconvenient, they cannot get through many places in a normal wheelchair that they or others can use. [0003] At present, the corresponding facilities are difficult to renovate due to small corners or old houses, and these problems canno...
