Detailed ways

Please refer to Fig. 1 to Fig. 3, the utility model comprises a vehicle body body 10, a left front wheel 20, a right front wheel 20' and a rear wheel set 30;

The front end of the vehicle body 10 is pivotally provided with a chainring 11, the axis of which is provided with a pedal 12, by stepping on the pedal 12, the chainring 11 is rotated, and the chainring 11 and the rear wheel group 30 are sleeved A chain 13, the chain 13 is used to drive the rear wheel group 30; and the middle end of the vehicle body 10 has a front wheel frame 14 extending to the left and right, and the left and right ends of the front wheel frame 14 are respectively provided with left movable buckles 141 And right movable buckle 141 ', then on the left and right movable buckle 141,141 ' of front wheel vehicle frame 14, pivot solid left and right front wheel 20,20 ', by means of this left and right movable buckle 141,141 ', make The left and right front wheels 20, 20' are in a deflectable state to the left and right. A steering structure is pivotally arranged at the center of the front wheel frame 14, and the steering structure includes a steering handle 15 and a linkage rod 16 coaxial with the steering handle 15. The linkage rod 16 is provided with a left cross bar 161 and a right cross bar 161', and the left and right cross bars 161, 161' are connected to the left and right movable buckles 141, 141' respectively, and the handle can be rotated in this direction to 15 and drive the linkage rod 16 coaxial with the direction handle 15, and then change the left and right fronts of the left and right movable buckles 141, 141' by the left and right cross bars 161, 161' of the linkage rod 16. Wheels 20, 20' travel direction, and then achieve the purpose of controlling the direction. The direction handle 15 is provided with a front brake handle 151 and a rear brake handle 152, which are used to control the left and right front wheels 20, 20 ' and a rear wheel group 30 brakes; A rear wheel frame 17, the rear wheel frame 17 pivots a rear wheel group 30, the rear wheel group 30 includes a rear wheel 31 and a flywheel 32 fixed on the axis of the rear wheel 31, the flywheel 32 is sleeved The chain 13 on the chainring 11. When the chainring 11 rotates, the flywheel 32 can be turned by the transmission of the chain 13, and then the rear wheel 31 is rotated as the power for the stunt car to advance. A seat portion is set at an appropriate place at the front end of the rear wheel frame 17, and the seat portion includes a seat cushion 18 and a seat back 181. The mud plate 182 is to prevent water stains and mud from being splashed on the user's body due to the rotation of the rear wheel.

When the utility model is in operation, please refer to Figure 4 and Figure 5, when the direction handle 15 is rotated by an angle α in the counterclockwise direction, the linkage rod 16 coaxial with the direction handle 15 will also rotate accordingly. angle α. Again, the left and right crossbars 161, 161' on the linkage rod 16 are fixed on the left and right movable buckles 141, 141' because of the other ends, so when the linkage rod 16 rotates counterclockwise by an angle α, The linkage rod 16 will make the right cross bar 161' push the right movable buckle 141', so that the right movable buckle 141' will be deflected by an angle α in the counterclockwise direction, and the right front wheel 20', which is pivoted on the right movable buckle 141', will also Deflect by an angle α in the counterclockwise direction; and the linkage rod 16 will make the left crossbar 161 pull back the left movable buckle 141, so that the left movable buckle 141 will deflect by an angle α in the counterclockwise direction, and the pivot is fixed on the left movable buckle 141 The left front wheel 20 is also deflected by an angle α in the counterclockwise direction; if the steering handle 15 is rotated clockwise by an angle β, the linkage rod 16 coaxial with the steering handle 15 will also rotate by the same angle beta. Again, the left and right crossbars 161, 161' on the linkage rod 16 are fixed on the left and right movable buckles 141, 141' because of the other ends, so when the linkage rod 16 rotates clockwise by an angle β, The linkage rod 16 will make the right cross bar 161' pull back the right movable buckle 141', so that the right movable buckle 141' deflects clockwise by an angle β, and the right front wheel 20' pivoted on the right movable buckle 141' It also deflects clockwise by an angle β; and the linkage rod 16 will make the left crossbar 161 push the left movable buckle 141, so that the left movable buckle 141 deflects clockwise by an angle β, and the pivot is fixed on the left movable buckle 141 The upper left front wheel 20 is also deflected by an angle β in the clockwise direction. Because of the linkage between the direction handle 15, the linkage rod 16 and the left and right front wheels 20, 20', the horizontal axis of the direction handle 15 and the axis direction of the left and right front wheels 20, 20' are always kept vertical, In this way, the user can simply and accurately control and change the traveling direction through the direction handle 15 .

Because the center of gravity and the seat cushion 18 of the utility model are closer to the ground than the existing stunt bicycles, the utility model can easily maintain balance during riding, even practicing or performing, without falling or overturning, and will not cause danger to the riders. And the set left and right front wheels 20, 20' can make the driver more stable when riding, performing or practicing.

Please refer to Fig. 6 to Fig. 8, Fig. 6 is the state when the stunt car of the present utility model is running normally, and in advancing, if the driver's own body deviates to the side, the position of the center of gravity is changed, such as the body moves to the right When the offset reaches a certain degree, the stunt car will use the right front wheel 20' and the rear wheel 31 as the axis of rotation, and the left front wheel 20 which is not on the axis of rotation will be subjected to the moment effect formed by the overall weight and rotate along the axis of rotation. The axis rotates, so the left front wheel 20 will leave the ground. As shown in Figure 7, the stunt car will move forward with the right front wheel 20 ' and the rear wheel 31 on the ground, and the left front wheel 20 in the air. Form a stunt posture that the existing stunt bicycle can't do, and vice versa, as shown in Figure 8, the center of gravity can also be deflected to the left, so that the right front wheel 20 ' is lifted off the ground.
