Transfer device

Abstract

The transfer device comprises wheels which replace sliding friction with rolling friction to assist the transfer device to move, the wheels comprise power wheels used for providing power and steering wheels used for steering, and the power wheels and the steering wheels jointly bear the weight of the transfer device and are matched with each other to complete the transfer action. The power wheels comprise a first power wheel and a second power wheel which are mutually independent and oppositely arranged, the steering wheels comprise a first steering wheel and a second steering wheel which are mutually independent and oppositely arranged, the first steering wheel and the second steering wheel are both Mecanum wheels, and the first steering wheel and the second steering wheel are arranged in a mirror symmetry mode. The device is stable in operation, has high adaptability to various grounds, can automatically clean obstacles on the ground, and is reliable to use.

Description

technical field [0001] The invention relates to the technical field of wheelchairs, in particular to a transfer device. Background technique [0002] According to the demographic data of our country in recent years, in 2018, the total population over the age of 65 in my country accounted for 11.94%. The daily travel of these elderly people has a relatively large dependence on wheelchairs; A large number of people who have lost walking function have been caused by troubles and so on. These elderly groups and people who have lost walking function make the society have an increasing demand for wheelchairs. And most of this group of people need to completely rely on wheelchairs for most of the time, so the comfort and safety of wheelchairs are very important. [0003] Most of the existing wheelchairs are designed as the rear wheels to push the wheelchair forward as the power wheels, and the front wheels are set as universal wheels as the steering wheels to facilitate steering wi...

Problems solved by technology

[0006] However, with such a setting method, it is difficult to ensure the normal control and rotation of the four wheels of the wheelchair when the power of the wheelchair is insufficient, so the direction of movement is prone to uncertainty

Moreover, when the four wheels are all Mecanum wheels, when encountering some rough ground, multiple wheels fail to touch the ground at the same time, or the angles of contact with the ground are different, it is easy to cause the four wheels to be difficult to form a combined force or a combined force. There is a deviation in the direction of the wheelchair, which causes the wheelchair to fail to move in the direction of the expected control, and then loses control and causes danger.
