The prior art seat is generally fixed on the bottom plate, however, the fixing mode is not flexible enough, operators can not conveniently get on or off the vehicle to operate at any time, and the operation in the actual tunnel has a plurality of working conditions to conveniently get on or off the vehicle.
3. The prior art automobile steering wheel power system is partially driven by a universal joint, however, the steering wheel is still fixed in position and cannot realize accompanying switching along with the bidirectional movement of the bidirectional automobile without well utilizing the performance of the universal joint.
4. For the exposed seat, although the safety of a driver can be improved through the form of a safety helmet and a safety belt, the posture of a person on a common seat is that the two feet are flush and arranged on the same plane, the gravity center is completely positioned on the buttocks, and the balance and the quick response capability of the person can be influenced by the posture, so that the seat is unfavorable for timely response in work.
5. The automobile pedal in the prior art can only realize the function of treading, but cannot realize the function of supporting the weight of a human body, thereby facilitating the more flexible adjustment of the position of the human body.
6. The automobile foot pedal in the prior art is generally arranged on a bracket close to a human body, which is a common design thought, but the design thought is not flexible enough, so that the space of the human leg is very limited.
7. For a simple car seat, the simple car seat has no suitable position for placing personal belongings of a driver or requires an additional storage structure.
