Description

Technical Field

[0001] The invention relates to a vehicle and provides a buckle-type multi-wheel vehicle which is light and suitable for traveling. Background Art

[0002] The progress and development of science and technology provide people with many kinds of transportation tools, such as urban rail, bus, high-speed rail, airplane, etc., but in metropolitan areas, there are a large number of vehicles, resulting in congestion, and there are problems of tight parking spaces and disorderly parking. It is necessary to have a vehicle that can be quickly folded and folded into a small volume when riding various large-scale transportation tools, which is easy to carry. Therefore, in the box-type tricycle (application number: 982481381), a car that can be folded into a box shape (application number: 200810127016.3), a box-type folding car (application number: 2009202787961, 2010201154998), a foldable box-type electric car (application number: 201420497841.3) and a reference box-shaped two-wheeled folding car (application number: 20072031109.6), a portable The invention is based on the optimization of box-type folding bicycles (application numbers: 201110045455, 2012103498753, 2011102423030), folding multi-wheeled bicycles (application number: 2017212540565), and automatic buckling multi-wheeled bicycles (application number: 202310708397.9). The present invention produces a buckling multi-wheeled bicycle, whose frame structure is suitable for two-wheeled, three-wheeled, four-wheeled vehicles and motorized and human-driven vehicles, and has good interchangeability of parts and components. The vehicle structure is simple and stable, and the operation is simple and fast. After buckling, the volume of the vehicle is reduced by about 3 times, which is particularly suitable for use as a shared vehicle. After buckling, the low body is easy to become a computer-controlled intelligent vehicle, which has positive significance for promoting the development of shared vehicles and has broad market prospects. Summary of the invention

[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. 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 is achieved in this way. It mainly consists of a rear wheel, a shock absorber, a seat support rod, a backrest plate, a connecting rod, a seat plate, a front wheel frame, a handlebar, a steering control, a cargo frame, a lamp, a front wheel, a pedal, a foot pedal, a locking pin, a guide wheel, a rear wheel frame and accessories. The front wheel frame is connected to the steering standpipe by the front end of a long longitudinal beam, the front fork is installed in the steering standpipe, the front fork is fixed with the front wheel, and the rear end of the beam of the front wheel frame has upper and lower The rear wheel beam is bifurcated by the rear end of the longitudinal beam, and an axle seat is provided at the rear end of the bifurcated beam. The rear wheel is mounted on the axle seat, and the rear wheel rod is hinged to the transverse axis of the rear wheel beam. One end of the shock absorber is hinged to the transverse axis set on the rear wheel beam, and the other end is hinged to the rear wheel rod to form the rear wheel frame, which improves riding comfort. The foot pedal is fixed to the lower end of the front wheel frame beam, and the upper end of the seat support rod is hinged to the seat plate transversely. The size of the vehicle can be changed by rotating these components relative to each other.

[0004] A connecting rod is laterally hinged at the front end of the rear wheel frame, and the other end is laterally hinged at the lower end of the seat support rod. The seat support rod and the rear wheel frame are linked, and a hook is provided at the transverse axis at the rear end of the beam of the front wheel frame, and there are blocks at the transverse axis at the corresponding rear wheel beam and the lower end of the seat support rod. After the seat support rod and the rear wheel frame are rotated to the expanded position, the hook is rotated to block the rotation of the seat support rod and the rear wheel frame, and a motor with gears is installed at the rear end of the beam of the front wheel frame, and there are gears corresponding to the hinge at the transverse axis of the seat support rod and the rear wheel beam, and the gear ratio is set accordingly, so that the seat support rod and the rear wheel frame are rotated to the expanded and retracted positions synchronously.

[0005] The handlebar is composed of a horizontal handle and a vertical tube in two L shapes. The lower end of the handlebar vertical tube is inserted into the handlebar slide sleeve. The handlebar slide is fixed on the axle seat of the front fork located at the steering vertical tube of the front wheel frame. The handlebar slide sleeve has a hole, and the corresponding handlebar vertical tube also has a hole. The handlebar vertical tube is slid to make the holes overlap, and then it can be fixed through a quick-release screw. The quick-release screw has a small rotating handle at one end and a thread at the other end. A nut is provided on the other side of the horizontal circular hole.

[0006] The handlebar can also be composed of a horizontal handlebar and a vertical tube, wherein the horizontal handlebar is two horizontally placed handlebar tubes hinged at the upper end of the vertical tube in a T shape, and the lower end of the vertical tube is hinged at the upper end of the front fork in a horizontal hinge. A horizontal round hole is opened at the overlapped part of the side of the axis to insert a quick release screw.

[0007] The existing hub motor is used, that is, the motor is installed at the position of the wheel hub, and a central shaft can be provided on the front wheel frame, on which a sprocket, chain and pedal are installed, 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 drives the rear wheel to rotate in a two-stage human drive. The existing mid-mounted motor or engine method can also be used. The existing motor control is generally composed of an output shaft, a reduction gear set, a position feedback potentiometer, a DC motor, a control circuit, etc., and a corresponding program can be compiled to control it. The shock absorber is generally composed of a rod and a spring, with shaft holes at both ends and variable length.

[0008] When in use, the rear wheel frame is rotated backwards, and after being locked, the vehicle can be ridden or taken by people. 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, and the guide wheel touches the ground. 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 can automatically travel between the boarding and disembarking positions and the garage where the vehicle is parked, which greatly facilitates users.
