Opening and closing type walking device

Abstract

The invention discloses an opening and closing type walking device which comprises at least one single-wheel assembly, each single-wheel assembly comprises a supporting plate, a main wheel flange and an inner wheel, the main wheel flanges penetrate through the supporting plates, the inner wheels and the main wheel flanges are coaxially arranged, an inner shaft penetrates through the centers of the main wheel flanges, and a walking driving mechanism and an opening and closing driving mechanism are arranged on the supporting plates. A driving bevel gear is embedded in the center of the inner wheel, the end of the inner shaft penetrates through the driving bevel gear, at least one opening and closing transmission assembly is arranged on the inner wheel and comprises a plurality of transmission lead screws, the transmission lead screws penetrate through the side wall of the inner wheel, and driven bevel gears are arranged at the ends, located on the inner side of the inner wheel, of the transmission lead screws. The end, located outside the inner wheel, of the transmission lead screw is sleeved with a sleeve, a transmission nut is fixed into the sleeve, and an arc-shaped outer wheel is fixed to the end, away from the inner wheel, of the sleeve. The wheel diameter is adjusted by driving the outer wheel to be opened or closed, and then the actions of going up and down stairs and crossing obstacles are completed.

Description

technical field [0001] The invention relates to a walking device, in particular to a retractable walking device. Background technique [0002] With the continuous development of intelligent and automation technology, transportation tools such as bicycles, electric vehicles, and automobiles are gradually popularized in every household, but these transportation tools can only be used by normal people with sound limbs. For the elderly and disabled people, Daily travel has become a luxury. Even though there are old scooters and electric wheelchairs on the market for them to travel, these tools can only provide them with activities on flat ground. Once they encounter stairs or obstacles, they cannot move forward. . In addition, the advent of the self-balancing car has brought a lot of convenience to people's travel. It does not need to be manipulated, and only needs to change the overall center of gravity to control the self-balancing car to move forward, backward, and turn left...

[0002] With the continuous development of intelligent and automation technology, transportation tools such as bicycles, electric vehicles, and automobiles are gradually popularized in every household, but these transportation tools can only be used by normal people with sound limbs. For the elderly and disabled people, Daily travel has become a luxury. Even though there are old scooters and electric wheelchairs on the market for them to travel, these tools can only provide them with activities on flat ground. Once they encounter stairs or obstacles, they cannot move forward.

In addition, the advent of the self-balancing car has brought a lot of convenience to people's travel. It does not need to be manipulated, and only needs to change the overall center of gravity to control the self-balancing car to move forward, backward, and turn left and right. However, the battery life of the self-balancing car is not strong. Stability It is not high, it is easy to fall during use, and it is generally difficult to drive on the road, and the operation of the balance car still needs to be controlled by the center of gravity of the human body, and it cannot navigate independently
