Problems solved by technology

The overly complex crawler system structure and impractical functions not only bring expensive equipment cost, but also are inconvenient and unsightly when driving on flat ground, and it is even more difficult to realize the portable and foldable performance of the wheelchair, which makes the wheelchair The practicability is very poor, and it is difficult to popularize to thousands of households
In addition, the current various electric tracked stair climbing wheelchairs are too focused on the functional design of climbing stairs, but do not pay attention to the characteristics of the wheelchair when driving on flat ground, making the current electric tracked stair climbing wheelchairs in practicality, There is a lot of room for improvement in terms of economy and convenience

Embodiment Construction

[0018] The principles and features of the present invention will be described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, not to limit the patent.

[0019] The crawler machine mainly consists of a crawler handle bracket (1), a crawler box (5), an electric control box (6), a main shaft (7), a wheelchair connection bracket (8), a worm gear reducer (9), a motor (10 ) and other components, such as figure 1 shown.

[0020] Caterpillar box (5) is made up of track, track support, driving wheel, driven wheel wheel and track tensioning device, and driving wheel and driven wheel are installed in the two ends of track support respectively. The crawler frame can be made of a metal rectangular tube (or square tube), which has an open long hole at one end and a closed long hole at the other end, such as Figure 4 , Figure 5 shown. The driven wheel axle is installed in the closed long hole of the crawler sup...

Abstract

An electric stair-climbing crawler machine is a carrying tool for carrying a wheelchair and a person on the wheelchair up and down stairs and is composed of a crawler box, a main shaft, a worm gear speed reducer, a motor, an electric control box and the like. The electric stair-climbing crawler machine can be easily integrated with the wheelchair through a crawler machine handle bracket and a wheelchair connecting bracket to form an electric stair-climbing wheelchair system. The electric stair-climbing crawler machine not only can be at the back of the wheelchair and make the wheelchair run onthe flat ground, but also can carry the wheelchair above the electric stair-climbing crawler machine and up and down the stairs, and the two working modes are convenient to convert. The electric stair-climbing crawler machine adopts wireless remote control operation; the electric stair-climbing crawler machine has the advantages of convenience in operation, simple structure, low cost and high practicability. The electric stair-climbing crawler machine can be equipped with a variety of hand-push (or electric) wheelchairs on the market to form different electric stair-climbing wheelchair systems so as to meet the needs of different users.

Description

[0001] (1) Technical field [0002] The invention relates to a wheelchair carrier, in particular to an electric transport device capable of carrying a wheelchair and simultaneously carrying the elderly, infirm and physically handicapped when climbing stairs. [0003] (2) Background technology [0004] In order to solve the difficulties of the elderly and the physically disabled when going up and down the stairs, provide them with more convenient means of transportation, help them improve their autonomy of action, and enable them to reintegrate into society better, people have developed electric crawler stairs A wheelchair, with the help of others, it can go up and down stairs, and it can be pushed on flat ground. [0005] The electric crawler-type stair-climbing wheelchair mainly uses the obstacle-surmounting ability of the crawler mechanism to realize the stair-climbing function, the movement mode is more continuous, the traction adhesion performance is good, and it is not eas...
