A stair climbing vehicle

Abstract

The invention belongs to the technical field related to robot walking mechanisms, and discloses a stair climbing loading vehicle. The stair climbing loading vehicle comprises a rack, two main side plates, two four-bar links, a stair climbing tow bar and friction wheels. The main side plates are fixedly connected to one end of the rack, and the two main side plates are separately located on two opposite sides of the rack. The two four-bar links are separately connected to the two main side plates, the two ends of the stair climbing tow bar are separately connected to the two four-bar links, andare separately provided with the friction wheels. When the stair climbing loading vehicle is in operation, the friction wheels are always attached to stairs so as to provide the friction required forthe stair climbing loading vehicle. By adopting the four-bar links, the stair climbing loading vehicle can be always attached to the stairs, the stability of climbing stairs is improved, and bumpingduring the stair climbing process and energy waste and cargo damage caused by bumping are reduced.

Description

technical field [0001] The invention belongs to the technical field related to the walking mechanism of a robot, and more specifically relates to a stair climbing vehicle. Background technique [0002] Most of the stair climbing mechanisms of existing stair climbing vehicles are planetary wheels, which cannot fit the stair surface well during the process of climbing stairs, and at the same time cannot correct the walking track when going upstairs, so that the stair climbing vehicle The process of climbing stairs and loading is not smooth. [0003] In actual work, if the loading vehicle cannot fit the stair surface well during the climbing process, it will make the loading process of the loading vehicle bumpy, resulting in extra waste of electric energy and damage to the goods, and the stability is relatively poor. Difference. In addition, when people operate the loading vehicle to go upstairs, they go backwards, and the loading vehicle cannot match the rhythm of people goi...

Problems solved by technology

[0002] Most of the stair climbing mechanisms of existing stair climbing vehicles are planetary wheels, which cannot fit the stair surface well during the process of climbing the stairs, and at the same time cannot correct the walking track when going upstairs, so that the stair climbing vehicle The process of climbing stairs is not smooth

[0003] In actual work, if the loading vehicle cannot fit the stair surface well during the climbing process, it will make the loading process of the loading vehicle bumpy, resulting in extra waste of electric energy and damage to the goods, and the stability is relatively low. Difference

In addition, when people operate the loading vehicle to go upstairs, they go backwards, and the loading vehicle cannot match the rhythm of people going upstairs, which affects the safety of people operating the loading vehicle and the speed of transporting goods.
