Embodiment 1

[0048] See attached Figure 1-4 , a stair climbing device, comprising a base frame 1, a seat plate 2, two front legs 3, two rear legs 4, two middle legs 5, a lead screw pair (a lead screw 6 and a lead screw nut 6-1), Slideway 7, motor 8, and wheel lifting mechanism.

[0049] A slideway 7 is set on the base frame 1, and the seat plate 2 is slidably installed on the base frame 1 through the slideway. Rigidly fixed with the base frame 1, the lead screw 6 is mounted on the base frame 1 through the rotation of the support, the motor 8 is fixedly installed on the base frame 1, and the output shaft of the motor 8 is connected with the lead screw 6 through a coupling, and the screw The rod nut 6-1 is fixedly connected with the seat plate 2, and the motor drives the seat plate and the base frame to generate lateral relative motion through the screw pair, that is, realizes the lateral relative motion between the middle leg and the front and rear legs.

[0050] The front legs, rear leg...

Embodiment 2

[0054] See attached Figure 5-16 , the climbing method of the climbing device is as follows:

[0055] 1. See attached Figure 5 , at first the fourth sensor of the front leg 3 of the stair climbing device detects contact with the side of the stairs, which is the initial position at this moment, and is ready to start climbing the stairs.

[0056] 2. See attached Figure 5-6 , the middle leg 5 of the stair climbing device is lifted to a set height (generally 3-5cm), the front leg and the rear leg are used as the supporting legs of the whole device, and then the motor acts to drive the seat plate and the middle leg to move forward in translation by the screw pair , and translate until the fifth sensor of the middle leg touches the side of the stairs, then the motor stops; then the middle leg 5 is lowered until the third sensor of the middle leg touches the ground.

[0057] 3. See attached Figure 7-9 , the middle leg is used as a supporting leg, and the front and rear legs ar...

Embodiment 3

[0062] See attached Figure 17 , On the basis of Embodiment 1, a handle 12 is arranged on the base frame, and the handle is arranged on the rear side of the base frame.

Abstract

The invention discloses a stair climbing device and a stair climbing method thereof. The stair climbing device comprises a base frame, a seat plate, two front legs, two rear legs, two middle legs, a lead screw pair, a slideway, a motor and a wheel lifting mechanism, wherein the seat plate is slidably mounted on the base frame through the slideway, the top ends of the middle legs are rigidly fixedtothe seat plate, the top ends of the front legs and the rear legs are rigidly fixed with the base frame, a lead screw is mounted on the base frame, the motor is connected with the lead screw, a leadscrew nut is fixedly connected with the seat plate, and the motor realize generating of transverse relative motion between the seat plate and the base frame through the lead screw pair. The wheel lifting mechanism is arranged at the bottoms of the front legs and the rear legs, and electric telescopic rods are adopted as supporting legs, so that the front legs and the rear legs and the middle supporting legs can adjust length, and forward movement is realized through the lead screw. Therefore, the front and rear legs and the middle supporting legs are lifted, retracted and moved forwards successively to climb stairs.

Description

technical field [0001] The invention belongs to the technical field of stair climbing devices, and in particular relates to a stair climbing device and a method for climbing stairs. Background technique [0002] Due to the fact that there are many six-story to top-floor buildings in the current urban area, and even seven-story to top-floor buildings, and most of them do not contain elevators. With the aging of the current social population, the elderly and people with disabilities are also increasing. , unable to accompany the elderly, causing inconvenience to these groups of people traveling. The phenomenon of staying at home is increasing day by day, which will be detrimental to people's mental and physical health in the long run. On the other hand, it is also very inconvenient for young people and old people to go upstairs when lifting heavy objects. Based on the above, a kind of stair climbing device is proposed. Contents of the invention [0003] The object of the ...
