Abstract

The invention discloses a hand drive and hand control differential gear transmission type walk alternative. The hand drive and hand control differential gear transmission type walk alternative comprises a trolley frame main body, a driving and steering mechanism, a speed changing mechanism and a braking mechanism. The trolley frame main body comprises a pedal and a semi-open trolley frame cover. The driving and steering mechanism comprises manipulation rockers, hollow casing pipes, ratchet mechanisms, side wheels and a rear omnidirectional wheel. The speed changing mechanism is arranged to bea planetary gear mechanism and achieves acceleration. A user holds handles at the upper ends of the manipulation rockers and pushes and pulls forwards and backwards to achieve power for moving forward. When the left hand pushes independently, turning right is achieved, and when the right hand pushes independently, turning left is achieved. The braking mechanism comprises a brake handle, a brake line and a disc brake. According to the walk alternative, the principle and structure break through the transmission method and steering operation mode of a traditional walk alternative, the user can operate in a stand mode, hand forward and backward pushing and pulling replace traditional walk alternative moving forward driven by foot treading, and therefore new human-computer interaction mode is achieved, and new potential of a brain is developed and physical coordination is developed.

Description

technical field [0001] The invention relates to a hand-driven hand-controlled differential gear transmission type walking substitute. Background technique [0002] Most of the traditional human-driven walkers are driven by pedals, and the steering is controlled by both hands. Some have complex structures and are expensive, and some are only suitable for specific groups of people and cannot meet the needs of all age groups. With the improvement of the economic level and the quality of life, people have high requirements for the appearance, especially the user interaction experience, while pursuing the fun, diversification and individualization of the walker. Contents of the invention [0003] The purpose of the present invention is to address the existing technical defects and provide a hand-driven hand-controlled differential gear transmission type walker, which has compact structure, stable and accurate transmission, stylish shape, good interactive experience, and breaks ...
