TECHNICAL FIELD

The present disclosure belongs to the technical field of two-wheel vehicles, and specifically relates to a two-wheel automatic balance reset mechanism and system.

BACKGROUND

The disclosure with Chinese Patent Application No. 200910254181.X discloses an overturn preventing device for a vehicle with two front wheels. The vehicle with the two front wheels comprises a frame with a hollow positioning piece, a front wheel unit corresponding to the positioning piece, and a steering unit used for controlling the front wheel unit. The overturn preventing device comprises a tilting unit pivoted to the positioning piece, and a locking unit used for locking the tilting unit, the locking unit is provided with a hydraulic locking mechanism integrated on the tilting unit, and the tilting unit is controlled to tilt relative to the positioning piece through the hydraulic locking mechanism such that the tilting unit is locked in time to avoid the overturn of the vehicle with the two front wheels caused by the tilting of the tilting unit relative to the positioning piece.

After the vehicle stops, a rider needs to adjust the vehicle by self in order to restore the vertical state of the vehicle, which is laborious and time-consuming; and if not adjusting the vehicle, the rider is very uncomfortable on the tilted vehicle.

SUMMARY

An objective of the present disclosure is to provide a simply structured, safe and comfortable two-wheel automatic balance reset mechanism, and system.

The objective of the present disclosure is achieved as follows:

the two-wheel automatic balance reset mechanism comprises a frame, a main vertical tube is fixedly arranged at the front end of the frame, a handlebar rod is, rotationally arranged in the main vertical tube, front wheel supports are symmetrically arranged on two sides of the main vertical tube, a balance bar is hinged between the frame and each front wheel support, the balance bar comprises a piston cylinder and a piston rod, the piston rod is movably arranged in a piston chamber of the piston cylinder, two ends of the piston chamber are mutually interconnected to form a first channel, a main control valve is arranged on the first channel and divides the first channel into a medium intake end and a backflow end, a medium tank is arranged at the backflow end, a pump is arranged at the medium intake end, and the pump is interconnected with the medium tank.

Preferably, the backflow ends of the two balance bars are connected with the same medium tank while the medium intake ends thereof are connected with the pump respectively through a left filling valve and a right filling valve.

Preferably, an energy storage tank is arranged between the left filling valve/the right filling valve and the pump, and a pressure sensor is arranged on the energy storage tank.

Preferably, the pump is driven by a motor, and a check valve is arranged at a liquid outlet end of the pump.

Preferably, the front wheel support comprises a main rod, a rotating seat and a damper, the damper is rotationally arranged at the, lower end of the main rod through the rotating seat, the main vertical tube is respectively hinged with the main rods through swing arm assemblies, a steering assembly is arranged between the handlebar rod and each rotating seat, and a front wheel is arranged at the lower end, of the damper.

Preferably, the swing arm assembly comprises a plurality of swing arms and first, rotating pins, and two ends of the swing arm are respectively arranged on the main rod through the first rotating pins.

Preferably, a group of symmetric swing arms are fixedly connected with a connecting plate, and a connecting rod is hinged between the two connecting plates.

Preferably, a main rotating component is hinged at the bottom of the handlebar rod, a secondary rotating component is hinged at each rotating seat, and a steering arm is hinged between the main rotating component and each secondary rotating component.

Preferably, the piston chamber and an interconnected chamber are arranged in the piston cylinder, and the upper ends of the piston chamber and the interconnected chamber are mutually interconnected through a normally opened main control valve while the lower ends thereof are mutually interconnected through an interconnected pore.

A two-wheel automatic balance reset system comprises the two-wheel automatic balance reset mechanism and a control system, the control system comprises a main control module and an acquisition module, the acquisition module comprises a balance sensor arranged on the frame and a speed sensor.

Compared with the prior art, the present disclosure has the following outstanding and beneficial technical effects:

the main control valve of the present disclosure achieves locking of the balance bars, and when the vehicle is tilted, the pump drives the balance bars to achieve automatic reset of the frame and quickly adjust the vehicle and the position of a rider such that the rider rides the vehicle more safely and comfortably; and

the present disclosure acquires a vehicle speed by the speed sensor and acquires a position of the vehicle through the balance sensor to automatically controlling the state of the vehicle in real time so as to have the characteristics of simple structure, high efficiency, convenience in use and the like.
