Description of the invention: [Technical field to which the invention pertains] The present invention relates to a folding machine that is suitable for carrying a power-driven two-wheeled vehicle (4) and whose turning line does not pass through the front surface of the front or rear wheel The range of projection is different from that of the private car on the steering wheel and the locomotive. [Prior Art] Generally, the steering of the bicycle and the locomotive utilizes the manner in which the front wheel is linked by the handle, so that the other wheel rotates by the axis of its own, and the vehicle body travels in the direction of the front wheel to achieve the steering objective. The bicycle is mainly advanced by foot. Although there is also a power type, even if power is used, the mechanism suitable for the foot, such as the pedal crank, the ratchet, the chain, etc., is usually retained. In recent years, many bicycles have been designed to be folded to facilitate carrying or not to make (4) save the space. The folding bicycles seen on the market are ^ n ; ^ # ; t * iii ί > It ^ ^ The product is still too large' Unable to meet the needs of some potential users. Of course, the general folding of the foot, the car has a considerable market, ‘quasi, if there is a better solution to the above volume: big 'overweight problem, will be more in line with the needs of some potential users. European patent EP i 600 368 Α2 is a folding wheel bicycle with a small wheel diameter, which needs to fold the crossbars 61, 67 when folding, and fold at least four steps of the seat cushion %, the handle, the frame 35, 73, etc. In the case of frequent folding and unfolding, its use will be more inconvenient, and it is designed as a small wheel diameter. Although it has 153706.doc 201236909, it is good for weight reduction, but it is not suitable for riding in poor road conditions. The folding step of the folding cart shown in US 2010/0289245 A1 includes the folding of the front and rear bodies 100, 101, the folding of the handle 30 at the front tube 401, and the folding of the seat cushion 101a. The folding vehicle includes a shock absorber, and the overall structure It is still complicated. The action of folding and unfolding is complicated, and the car body is higher than the wheel. Although it can be pushed and pulled after folding, the volume is still too large, which is unfavorable to carry around. Looking at the above two folding bikes, there are some disadvantages such as folding, unfolding operation, or folding the car body is still too large to carry around. Therefore, how to overcome these shortcomings has become a problem that people in this technical field want to solve. SUMMARY OF THE INVENTION The power two-wheeled vehicle of the present invention is designed to be portable, so that it is foldable, and the structure is designed to be light and compact, so that the pedaling mechanism and the steering mechanism of the conventional bicycle are omitted. Seat cushions and other components to increase their portability. θ The two-wheeled vehicle that can be carried with the present invention is different from the bicycle and the locomotive in that the steering system utilizes the pivoting axis between the front and rear wheels to rotate the shaft 'or more precisely, or not Through the pivot axis of the orthographic projection range of the front or rear wheel, the axis rotates, which is easy to say, _ through the front wheel

The front and rear wheel mounts are connected in a towable manner, and the complex joint forms a pivot axis. The pivot axis is used as a steering wheel: a rotation axis, and the rider uses the steering when riding The handle can manipulate the relative pivoting of the "rear wheel mount to turn the vehicle body. When the two wheels of the present invention are carried or placed, they can be converted into a folded state. The finger stack is along the pivot axis. The front and rear wheel mounts rotate relative to each other, and the two-wheeled vehicle of the present invention can also be combined with the size of the front and rear wheel mounts (length:) to add a second pivot shaft so that when folded, they are mutually along the axis Relative rotation, and thus overlap each other. After the shaft and the rear wheel fixing frame are overlapped, the steering handle is folded to the rear, and the vehicle body becomes a two-wheeled vehicle with a weight similar to a towed hand luggage, which is convenient for carrying Carrying. In addition, in the road wheel 'can also drag the two-wheeled vehicle like a towed suitcase - (4) The hand-folded part only has the front and rear wheel fixing brackets and the steering handle t...1 step I, easy.

Fig. 4 is a side view of the system 3. The front wheel fixing frame 16 support - front wheel 22 'rotates the front wheel 22 relative to the front wheel mount 16; the rear wheel mount 18 supports a rear wheel 12 for the rear wheel to listen to (four) the rear wheel mount; the steering handle Working on the front wheel mount 16. The front wheel mount 16 and the rear wheel mount 18 are connected in a rotatable manner. The pivot joint forms a pivot axis A (the first pivot axis) that is configured to pass the front (four) or the rear. The orthographic projection range of the wheel surface of the wheel 12 is easy to say 4. The pivot axis 8 is different from the commonly used bicycle in the manner that the L drawing line of the front wheel orthographic projection range is not rotated by the axis of the front wheel. By steering the steering handle 2, the front wheel mount is pivoted with the pivot axis A as an axis, thereby turning the vehicle body. The front and rear wheel mounts 16, 18 of the two-wheeled vehicle can be folded along the drag axis a. It does not occupy the work space and is suitable for carrying out the two-wheeled vehicle. The circular 5 series is simplified in structure. Figure 6 is a top view showing the front and rear wheel fixings 16, 18 with the pivot axis A as the axis of rotation and the arrow. The direction indicated by c, after the weight is stacked, as the circle 7 is. Turning the steering handle 20 in the direction toward the front and back ^ will become the state shown in Fig. 8. As above, the car has a simple structure and a light weight, and the folding handle structure is removed. In addition, it is generally not obvious. = 153706.doc • 6 - 201236909 After the tow wheel 24 is installed, the chest is generally suitable for carrying. That is, as shown in FIG. 9 , the difference between the present invention and the general folding mechanism of the general bicycle and the above-mentioned bicycle, the detailed structure of which will be described later in detail with reference to FIG. 5 and FIG. 6 . The front wheel fixing frame 16 and the rear wheel fixing frame 18 are connected in a sleek manner, and the connection mode shown in FIG. 5 is a money chain connection, and other pivotable manners are also suitable. The pivoting portion forms an axis A. The front and rear wheel fixing frames 16, 18 are pivoted with the axis A and pivoted in the arrow=c direction shown in FIG. 6, and then the two can be folded together as shown in FIG. The status shown. Since the front and rear wheel axles generally protrude from the wheel surface, the lengths of the front and rear front wheel brackets 16, 18 can be appropriately designed so that the front and rear axles are staggered after folding, and the smaller folded volume is obtained. The steering handle 20 is pivotally mounted to the vehicle body. In the embodiment of Figures 7 and 8, the steering handle 20 is attached to the front wheel mount 16.
