Detailed Description

Embodiments of the present invention are described in more detail below with reference to the accompanying drawings.

The stair climbing device shown in fig. 1 comprises a vehicle frame 1, a seat 2 part for a human body to sit on and a traveling mechanism 3 for traveling and climbing stairs, wherein the seat 2 part and the traveling mechanism 3 are installed on the vehicle frame 1. The travelling mechanism 3 comprises a turning wheel 31 and an auxiliary wheel for assisting the turning wheel 31 in climbing stairs, the auxiliary wheel and the turning wheel 31 being driven by a travelling belt 34.

The auxiliary wheel can be opposite to the rotating wheel 31 by taking the rotating shaft of the rotating wheel 31 as a rotating shaft, and when the stair climbing device moves on a flat ground, the auxiliary wheel is folded, so that the auxiliary wheel does not contact with the ground when the stair climbing device moves on the flat ground, and the stair climbing device moves on the ground through the rotating wheel 31. The climbing angle of the stair climbing device can be adjusted by rotating the whole set of stairs, so that the stair climbing device is suitable for various gradients, the auxiliary wheels can be packed up when the stairs are not climbed, and normal running is not influenced.

In order to facilitate the adjustment of the angle of the auxiliary pulley without rotating the rotating pulley 31, the rotating pulley 31 can adjust the distance between the auxiliary pulley and the rotating pulley 31 to the left and right along the line of the crawling angle, and adjust the degree of tension of the belt.

The height of the staircase is generally set at 15 to 18 cm, and the depth of one step surface is 22 to 27 cm, so that the distance between the adjacent step surfaces is 26.6 to 32.4 cm. Therefore, the distance between two points of the auxiliary wheel and the rotating wheel 31 contacting with the ground is necessarily larger than the distance between the adjacent step surfaces, so that the stair climbing device can be ensured to climb stairs smoothly without step feeling. Specifically, in order to make the crawling more gradual, a rotating wheel 31, an auxiliary wheel and a plurality of supporting wheels 33 for supporting a traveling belt 34 are arranged in one traveling mechanism 3, the supporting wheels 33 are arranged between the auxiliary wheel and the rotating wheel 31, and a connecting line of rotating shafts of the plurality of supporting wheels 33 is parallel to a straight line of the traveling belt 34 which is arranged between the driving wheel and the auxiliary wheel and is contacted with the ground.

As shown in fig. 2, the stair climbing vehicle in this embodiment is provided with three rotating wheels 31, including a front rotating wheel and two rear rotating wheels, wherein the rear rotating wheel is a driving wheel, and the front rotating wheel is a driven wheel. When a plurality of stair climbing devices climb up the rotary stair, the stair climbing devices are difficult to turn around in the rotary stair due to the fact that the stair climbing devices do not have turning capacity. In this embodiment, the front wheel is fixed on frame 1, and can rotate relative frame 1 itself and change the direction of travel, and the adjustment of front wheel direction of travel can change the direction of whole building device of climbing, guarantees that the building device of climbing in this embodiment can directly turn on the platform of gyration stair, and is nimble convenient. In addition, the pedals 6 are also rotatably arranged on the frame 1, and when the advancing direction of the front part begins to change, the angle of the pedals 6 is changed along with the change.

fig. 3 is a schematic diagram of the process of going upstairs by the stair climbing device, and the stair climbing process of the stair climbing device is described with reference to fig. 3:

In fig. 3(a), when the stair climbing device goes up stairs, the auxiliary wheel on the driven wheel descends to touch the first step by taking the rotating shaft of the driven wheel as a center, then moves forwards, and climbs the front of the stair climbing device by the action of the traveling belt 34 between the three rotating wheels 31 and the auxiliary wheel. The auxiliary wheelers corresponding to the rear rotating wheels 31 are in the stowed state. In fig. 3(b), the front wheel and the corresponding auxiliary wheel of the stair climbing device completely climb up the stairs, and the auxiliary wheel rotates and descends along the rotating wheel 31 in the process of climbing the first step until the auxiliary wheel stops after the auxiliary wheel cannot descend continuously. When the stair climbing device continues to advance forwards, the rear wheel and the corresponding auxiliary wheel are close to the first step in fig. 3(c), and the auxiliary wheel controlling the rear wheel rotates and descends along the rotating shaft of the rear wheel until contacting with the first step. Then, the auxiliary wheel of rear wheel is rotated to ground direction at the in-process of advancing always and is known unable continuation decline, and the front wheel and the rear wheel of climbing the building device all climb on stair this moment, rotate and be equipped with supporting wheel 33 between wheel 31 and the auxiliary wheel, can support advancing belt 34, guarantee that advancing belt 34 can not receive the application of force of step at the building in-process of climbing, guarantee to climb the life of building device. As shown in fig. 3 (e). When the stair climbing device moves to the end of the stair, the auxiliary wheels of the front wheels are retracted, and the stair climbing device continues to move forward under the action of the rear wheels to safely climb up the stair.

The stair climbing device is similar to the stair climbing process in the stair descending process, the auxiliary wheel of the front wheel is controlled to descend to be in contact with the first step, the auxiliary wheel is continuously adjusted to rotate in the advancing process, and finally the stair climbing device climbs down.

during the travelling process of the stair climbing device, the rotating wheel 31 and the auxiliary wheel are driven by the travelling belt 34. Whether the stair climbing device walks on flat ground or goes upstairs or downstairs, the rotating wheel 31 drives the traveling belt 34 to contact with the ground or stairs for movement. In the present embodiment, the traveling belt 34 may be a belt or a crawler belt.

When the stair climbing device climbs stairs, the angle of the seat, the angle of the handle 41 and the length of the handle 41 are changed correspondingly along with the change of the inclination angle and the gravity center of the vehicle body. Specifically, a seat 2 adjusting device for adjusting the angle of the seat 2 is further included, and the seat 2 is mounted on the bracket through the seat 2 adjusting device. The frame 1 comprises a handle 41 and an angle adjusting mechanism, wherein the handle 41 is fixed at the front part of the stair climbing device through an angle adjusting device 42, and the handle 41 can be arranged in a telescopic way. Still include rotary mechanism 5, the anterior running gear 3 passes through rotary mechanism 5 rotatable setting, and rotary mechanism 5 includes horizontal axle 51 and perpendicular pivot 52, and the running gear 3 in the front is fixed through horizontal axle 51 on the perpendicular pivot 52, the vertical setting of perpendicular pivot 52 is on frame 1, and horizontal axle 51 is scalable to be set up.

The above is the preferred embodiment of the present invention, and a person skilled in the art can make several modifications and improvements without departing from the principle of the present invention, and these should also be regarded as the protection scope of the present invention.
