Track wheel vehicle with driving seat capable of rotating along with stairs and road slopes

Abstract

The invention provides a track wheel vehicle with a driving seat capable of rotating along with stairs and road slopes. The track wheel vehicle can avoid forward and backward tilting when running on the stairs. A pair of angle steering devices are installed at a gravity center between a front wheel and a rear wheel of a chassis of the track wheel vehicle and on the axis parallel to a front axle and a rear axle. Rotary plates of the angle steering devices are fixedly connected to the seat, and an angle sensor installed on the seat (or the chassis) senses angle changes between the seat and the ground to control the seat to rotate by a corresponding angle. The gravity center of a passenger is automatically adjusted according to the gradient so that the vehicle can not tilt forwards and backwards easily. The passenger automatically keeps the same posture when driving the track wheel vehicle to go upstairs and go downstairs and driving the track wheel vehicle on the flat ground, and auxiliary drivers are not needed. A track wheel is composed of a track gear hub, a track and a tire installed on the outer side of the track. The track gear hub drives the track and the tire to coaxially and synchronously rotate. The track mainly bears force and the tire assists in bearing force when the vehicle goes upstairs and downstairs. On the contrary, the tire mainly bears force and the track assists in bearing force when the vehicle runs on the flat ground. A vehicle for going upstairs and a traveling vehicle are combined.

Description

Technical field [0001] The invention relates to a safety device for automatically adjusting the center of gravity when going up stairs and when traveling with people, in particular, it can prevent the car from tipping forward and backward when running on the stairs. A crawler vehicle in which the driving seat and the passenger seat rotate with the gradient of the stairs as the main crawler Background technique [0002] At present, the center of gravity of the known stair-carrying occupant is fixed, and moving the center of gravity backward or forward when going up and down stairs will easily cause the vehicle to roll backward or forward. The car going up the stairs needs to be driven by an auxiliary person on the stairs to maintain the balance of the car. It cannot be driven by the occupants themselves. The stairwell turns.

Problems solved by technology

[0003] In order to overcome the disadvantages that the existing stair car is easy to roll forward or backward, the occupants of the stair car cannot drive up and down the stairs and travel by themselves, and the long body is not conducive to turning in the stairwell, the invention provides a driving seat that can be used with the stairs. Wheeled vehicle that rotates with the road gradient
