Embodiment Construction

[0058] The following technical solutions of the present invention are further described in conjunction with the accompanying drawings and by specific embodiments.

[0059] as Figures 1 to 3 As shown, a climbing deformation wheel group, comprising a deformation device and two symmetrically arranged crawling wheel groups, which are characterized by:

[0060] Each of the crawling wheels comprises two special-shaped deformation wheels 11 with consistent morphology before and after, wheel set transmission mechanism 12 and wheel group bracket 13;

[0061] The special-shaped deformation wheel 11 is composed of a morphologically consistent external spiral special-shaped wheel 111 and an internal spiral special-shaped wheel 112, and an alien-shaped wheel displacement device 113; The two spiral special-shaped wheels 111 and 112 are arranged in a coaxial vertical cross-arrangement, relying on the special-shaped wheel displacement device 113 active connection;

[0062]The two special-shaped d...

Abstract

A stair-climbing deformation wheel set, including a crawling wheel set and a deformation device, its technical characteristics are: each of the crawling wheel sets includes two front and rear special-shaped deformation wheels with the same shape, a wheel set transmission mechanism and a wheel set bracket; The special-shaped deformation wheel is composed of an external spiral special-shaped wheel, an internal spiral special-shaped wheel, and a special-shaped wheel displacement device; the two spiral special-shaped wheels are coaxial and vertically crossed, and are flexibly connected by the special-shaped wheel displacement device; The two special-shaped deformation wheels in the crawling wheel set are parallel to each other and are respectively connected in the wheel set bracket, and the special-shaped deformation wheels are mutually transmitted through the wheel set transmission mechanism and rotate synchronously; the deformation devices are respectively connected to the crawling wheel set and the carrier The car body has a structure including a horizontal deformation device and a vertical deformation device. The design of the present invention can be applied to a manual trolley or an automatic carrier equipped with a power device, and it does not need to use crawlers to climb stairs more smoothly.

Description

Technical field [0001] The present invention relates to a mechanical vehicle, specifically a deformed wheel group capable of smoothly crossing the stairs. Background [0002] In the urban environment, automated commuting and transportation need to face the problem of climbing stairs without elevators to a greater or lesser extent. Especially for the elderly or disabled travel and medical assistance stretcher movement and other special needs occasions, once the stairs encountered, it will bring great inconvenience. [0003] In order to solve this problem, there are many forms of stair climbing machine design. There are four common types: stepper, lever, compound wheel and track type. Step-by-step is inefficient, difficult to run smoothly, requires complex control systems, and is therefore not very practical. The track type requires that the track length can span three steps, the friction of the narrow track is too large, the transmission efficiency is low, and it is not suitable f...
