[0003] The purpose of the present invention is not only to provide a vehicle that satisfies people's riding comfort and safety, but also can be buckled, and after buckling, the appearance is regular and the volume is small. Its structure is suitable for two-wheeled, three-wheeled and four-wheeled vehicles. It mainly uses a screw or a pulley group, and its automatic operation is controlled by a motor. It is achieved in this way. It mainly consists of a rear wheel, a shock absorber, a seat support rod, a backrest plate, a seat support connecting rod, a seat plate, a front wheel frame, a handlebar, a handlebar sliding sleeve, a steering control, a screw, a screw slider, a handlebar connecting rod, a cargo frame, a headlight, a front wheel, a pedal, a middle shaft connecting rod, a foot pedal, a seat connecting rod, a locking pin, a rear connecting rod, a guide wheel, a rear wheel frame and accessories. The front wheel frame is composed of the front end of the long longitudinal beam connected with the steering standpipe, the front fork is installed in the steering standpipe, the front wheel is installed under the front fork, and the rear end of the long beam is provided with a transverse axle hole, the rear wheel frame is formed by the rear end of the longitudinal beam being forked, and a transverse axle seat is fixed on the rear end of the fork, and the rear wheel is installed on the axle seat, the rear end of the front wheel frame long beam is transversely hinged to the axle hole at the front end of the rear wheel frame, and the hinge axis is located after buckling, at the rear lower end of the rear wheel, the seat support rod is transversely hinged at the rear end of the front wheel frame beam, the other end of the seat support rod is transversely hinged to the seat plate, a connecting rod is hinged on the transverse axis of the seat support rod, the other end of the connecting rod is hinged to one end of the shock absorber, and the other end of the shock absorber is transversely hinged at On the rear wheel frame support arm, the seat support link is laterally hinged at the rear end of the front wheel frame beam, and the other end of the seat support link is laterally hinged to the seat plate, so that the seat support rod, the front wheel frame beam, the seat plate, and the seat support link form a four-link rod. The fixed support frame on the front wheel frame beam holds the longitudinal screw, and the screw end is connected to the fixed motor shaft. The screw has a screw slider with corresponding internal threads and transverse axial holes, and the axial holes are respectively hinged to the rear link, the seat link and one end of the handlebar link. The other end of the rear link is hinged to the rear wheel frame, and the other end of the seat link is hinged to the seat support link. The handlebar is composed of a crossbar and a vertical tube. The crossbar is two horizontally placed handlebar tubes hinged on the vertical tube. The upper end of the tube is T-shaped, and the lower end of the vertical tube is inserted into the handlebar slide. The handlebar slide is laterally hinged on the axle seat at the steering vertical tube of the front wheel frame. The two ends of the handlebar connecting rod are respectively hinged to the lower end of the handlebar slide and the screw slider. One end of the middle axis connecting rod is hinged to the screw slider, and the other end is laterally hinged to the middle axis support arm of the pedal. The pedal is fixed on the long beam of the front wheel frame, and a battery box is arranged below. The space is sufficient for the installation of battery packs, etc. The connecting rod is hinged on the horizontal axis of the rear wheel frame, and the other end of the connecting rod is laterally hinged to one end of the shock absorber, and the other end of the shock absorber is laterally hinged to the arm of the rear wheel frame. The shock absorber is generally composed of a rod and a spring, with axial holes at both ends and variable length.

[0004] A fixed support frame on the front wheel frame beam can be used to hold the transverse axis of the main pulley group, and the axis is connected to the fixed motor shaft. The front wheel frame, rear wheel frame, and seat support rod transverse hinged axis are equipped with corresponding slave pulleys. The steel cables are respectively tied to pulleys of different diameters of the main pulley group, bypassing the slave pulleys and tied to the rear wheel frame and the seat support rod. Similarly, the other end of the steel cable is connected to the lower end of the handlebar slide sleeve, one end of the steel cable is connected to the main pulley group, and the other end of the steel cable is connected to the pedal middle axis support arm to form a closed loop, and a push-pull electromagnetic rod is fixed on the seat support rod. The push-pull electromagnetic rod consists of a coil and a plug rod with a magnetic end in the coil. The control coil is powered on or off, and the plug rod is extended and retracted under the electromagnetic action of the coil. There is a cross pin at the front end of the plug rod, and the cross pin is located in the radial slide groove of the seat support rod, facing it. The front wheel frame, rear wheel frame and pedal center axis arm also have radial slide grooves. Through the forward and reverse rotation of the motor, the pulleys of different diameters of the main pulley group and the front wheel frame, rear wheel frame, handlebar slide sleeve and pedal center axis arm are selected after calculation, and the front wheel frame, rear wheel frame, handlebar slide sleeve and pedal are synchronously pulled to rotate around the transverse hinge axis. After reaching the position, the seat support rod and the front frame beam are rotated until the radial slide groove coincides, and the insertion rod pushes the cross pin to slide into the seat support rod and the corresponding front wheel frame, rear wheel frame and pedal center axis arm The end of the slide groove coincides prevents the front wheel frame, rear wheel frame, and pedal center axis arm from rotating. Similarly, the lower end of the handlebar and the front fork steering tube of the front wheel frame adopt this method, and the electric push rod is used to pull the cross pin out of the groove to achieve unlocking, and sprockets and chains can also be used instead of steel cables and pulleys.

[0005] When the door is not opened and closed frequently, a horizontal circular hole is opened at the overlapping part of the side of the rear wheel frame, the seat support rod and the horizontal hinge axis of the front wheel frame to insert a locking pin. The locking pin has a small rotating handle at one end and a thread at the other end. A nut is correspondingly arranged on the other side of the horizontal circular hole.

[0006] A sliding pin can also be used, that is, a radial groove is provided at the hinge shaft, and the sliding pin is located in the groove on the rod shaft seat. After the other rod groove is rotated to overlap, the spring pushes the sliding pin into the groove and locks it. Pulling the handle ring drives the sliding pin out of the groove to unlock it.

[0007] The backrest plate and the seat plate can be integrated into a seat, the upper end of the seat support rod is fixed to the seat plate, and the seat support connecting rod is cancelled, so that the frame structure is simpler.

[0008] Steering control is to install a servo at the position of the steering riser of the front wheel frame, and use the motor to drive the rudder arm to rotate the front wheel. The servo is a position (angle) servo driver. Generally speaking, the servo is mainly composed of the following parts: steering wheel, reduction gear set, position feedback potentiometer, DC motor, control circuit, etc., and the corresponding program is compiled to control it. It is suitable for control systems that require the angle to change continuously and be maintained.

[0009] The existing hub motor is used, that is, the motor is installed at the position of the wheel hub; a central shaft can be provided on the front wheel frame, and a sprocket, chain and pedal are installed on the central shaft, and the pedal is located at the lower end of the front wheel frame beam. In this way, the sprocket is driven to rotate by rotating the pedal, and the chain drives the front wheel frame, the seat support rod and the flywheel on the hinge shaft of the rear wheel frame to rotate, and the flywheel then drives the rear wheel to rotate in a two-stage human drive; the existing mid-mounted motor or engine method can also be used.

[0010] A parallel linkage mechanism is formed on the two front wheel axles with connecting rods, one end of the rocker arm is connected to the connecting rod, the handlebar riser is inserted into the front fork steering rod in the front wheel frame steering riser, and the lower end of the rod is connected to the other end of the rocker arm. The rotation of the handlebar causes the two front wheels to steer synchronously. A transmission that connects the handlebar riser and the front fork steering tube can also be achieved by using a universal shaft.

[0011] The rear wheel is a single wheel, making it a two-wheeled vehicle. In this example, a guide wheel support arm is laterally hinged on the rear wheel frame arm. The guide wheel arm and the rear wheel frame arm are pulled by an eccentric spring to allow the guide wheel to touch the ground during the engagement process. The guide wheel is used to prevent the vehicle from tipping over after engagement, just like a bicycle kickstand.

[0012] When in use, the motor drives the lead screw to rotate, which moves the lead screw slider, and the connecting rod pushes the rear wheel frame to open and close, while changing the angle of opening and closing between the seat support connecting rod and the front wheel frame beam, as well as standing up and putting it on the handlebar. After locking, the vehicle can be ridden by people, and the power component and the brake disc are controlled by the handle of the handlebar through the control line to make the vehicle move forward or stop. When not in use, the vehicle is buckled, the guide wheel touches the ground, and it can be parked or pushed or pulled by the wheels. The advantage is that the low vehicle body after buckling makes it easy to become an intelligent vehicle controlled by a computer, and it can automatically travel back and forth between the boarding and disembarking positions and the garage where the vehicle is parked, which is convenient for users.
