Embodiment 1

[0044] Such as figure 1 , 2 As shown, a stair climbing device includes a chassis 1, a slewing frame 2, a running wheel 3, a stair climbing wheel 4, a push-pull mechanism 5, a driving mechanism 6, a transmission mechanism 7, a rotating wheel 8, a clutch 9, spokes 41, a first Pulley 71, second pulley 72, belt 73, roller 81.

[0045] Such as figure 1 , 2 As shown, the chassis 1 is a bracket, which provides attachment points for other parts of the stair climbing device, its rear end is provided with the hinge hole of the slewing frame 2, and its front end is provided with a shaft for installing the rotating wheel 8 and for hinged The hinge hole of the push-pull mechanism 5 and the first end of the chassis 1 are hingedly provided with a swivel frame 2 .

[0046] In the present embodiment, the slewing frame 2 is hinged on the rear end of the chassis 1, as Figure 5 Shown is a perspective view of the revolving frame 2, the revolving frame 2 is provided with a revolving frame hin...

Embodiment 2

[0053] The difference between this embodiment and Embodiment 1 is:

[0054] The stair climbing wheel 4 is installed on the revolving frame 2 (not shown in the figure), specifically, the stair climbing wheel 4 is installed on the revolving frame 2 near the hinge axis of the revolving frame 2, so that the running wheel 3, climbing Landing wheel 4 alternately shall prevail.

[0055] Such as Figure 6 , 7 As shown, the stair climbing wheel 4 includes spokes 41 , sliders 42 , elastic bodies 43 , and crawling soles 44 .

[0056] The second end of the spoke 41 is slidably provided with a slider 42, the sliding direction of the slider 42 is parallel to the spoke 41, and an elastic body 43 is arranged between the first end of the slider 42 and the spoke 41, the elastic body in this embodiment 43 is a compression spring, and the elastic body 43 can also be set to rubber as required, and the second end of the slide block 42 is hingedly provided with a crawling foot 44, and the hinge a...

Embodiment 3

[0061] The difference between this embodiment and Embodiment 1 is:

[0062] Said traveling wheel 3 described in the present embodiment is installed on the chassis 1 (not shown in the figure), and stair-climbing wheel 4 is installed on the slewing frame 2, present embodiment only uses traveling wheel 3 and stair-climbing wheel with respect to embodiment one 4. The positions are exchanged, and the diameters of the two are adaptively adjusted to ensure that the two can alternately land on the ground under the drive of the push-pull mechanism 5 .

[0063] working principle:

[0064] A kind of stair-climbing device in the present invention, in the actual use process, mainly is divided into two kinds of working modes, and the first kind of mode is the flat ground mobile mode, namely as image 3 In the state shown, when moving on flat ground, the push-pull mechanism 5 drives the slewing frame 2 to swing, the driving wheel 3 touches the ground, the stair climbing wheel 4 is suspended...

Abstract

The invention discloses a stair climbing device. The device comprises a chassis, a running wheel, a stair climbing wheel, a push-pull mechanism with two ends respectively hinged at the chassis and theslewing frame and a driving mechanism, a first end of the chassis is hingedly provided with a slewing frame, a hinge shaft is horizontal and perpendicular to the moving direction of a stair climbingdevice body, the movable end of the driving mechanism is connected to the running wheel, the driving mechanism is in one-to-one correspondence with the running wheel, and the running wheel and the stair climbing wheel are driven by a drive mechanism; the running wheel is installed on the slewing frame, the stair climbing wheel is mounted on the chassis, or the running wheel and the stair climbingwheel are all mounted on the slewing frame, or the running wheel is mounted on the chassis, and the stair climbing wheel is mounted on the slewing frame; under the push-pull action of the push-pull mechanism, the slewing frame swings, and the alternate landing of the running wheel and the stair climbing wheel can be achieved; a rotating wheel is further included, and a rotating shaft of the rotating wheel is parallel to the hinge shaft of the slewing frame. The device has the advantages that the structure and the principle are simpler, and the movement is flexible and reliable.

Description

technical field [0001] The invention relates to the field of stair climbing equipment, in particular to a stair climbing device. Background technique [0002] With the aging population and industrial upgrading, the demand for electric wheelchairs is increasing year by year. Traditional electric wheelchairs do not have the function of climbing and climbing stairs, and are not suitable for outdoor complex road conditions, which limits the travel of users. In recent years, stair-climbing wheelchairs have been introduced in domestic and foreign markets. Whether they are crawler-type or planetary-type, in addition to a pair of motors for walking on flat ground, the wheelchair also needs to be equipped with a stair-climbing motor and a corresponding reduction mechanism. Not only does it increase the cost, but when a separate stair-climbing motor is used, the stair-climbing deceleration mechanism does not have a turning function when the stair-climbing deceleration mechanism is fix...
