The present invention relates to a steering control structure design of a three-wheeled tailgate, and more particularly to a steering wheel that allows a user to easily manipulate a lever located in front of it to control the shaft unit.

According to the "three-wheeled bicycle" of the Republic of China Patent No. 200624319, the frame has a non-rotating front fork, a front wheel is arranged on the front fork, and a parallel four-bar linkage mechanism is arranged on the rear part of the frame. The rear wheels are respectively disposed on the two side rods of the four-bar linkage mechanism; in addition, the parallel four-bar linkage mechanism is additionally provided with two handles respectively located on two sides of the seat cushion of the three-wheel bicycle; thereby, the user doubles The hand controls the two handles to make the parallel four-links act, so that the two rear wheels are turned to cause the steering of the vehicle body, and the vehicle body is tilted toward the turning direction. When the vehicle speed is fast, the steering action can cause the "tail". (tail slide) effect.

Although the above-mentioned "three-wheeled bicycle" can achieve the effect of the appendix; however, since the handle is located on both sides of the seat cushion, the user will have his hand on both sides of the buttock after the ride, thereby causing the user The hand will be in close proximity to the position of the waist, making the position of the handle less ergonomic, resulting in a more laborious and unsmooth operation when the user moves the handle back and forth.

Therefore, in order to improve the above-mentioned shortcomings, the creators of this case have devoted themselves to research and development of a "three-wheeled tailgate steering control structure" to effectively improve the shortcomings of the use.

The main purpose of this creation is to make it easy for the user to control the hinge unit to achieve the steering effect. In order to achieve the above object, the present invention provides a three-wheeled tailgate steering control structure, which comprises: a frame and a steering control mechanism, wherein a front fork is fixed at one end of the frame, and the front fork is combined with a front wheel. The other end of the frame is provided with a rotating shaft unit, and the two sides of the rotating shaft unit are respectively combined with a rear wheel; the steering control mechanism is combined with the frame movement, and comprises a sleeve portion disposed adjacent to the front fork, and a pair of respectively The movable rods disposed on the two sides of the sleeve portion and the pair of connecting rods respectively connecting the rotating shaft unit and the pulling rod, when the user pushes and pulls the pulling rods respectively, the respective pulling rods respectively link the connecting rods to control the rotating shaft unit to perform steering .

In an embodiment of the present invention, the shaft unit includes an axle for combining the two rear wheels, correspondingly disposed on the axle and spanning the upper and lower axle plates at the other end of the frame, and a laying device. The lower shaft plate and the pivot on the frame, and one end of each linkage rod is connected to the pull rod, and the other end is connected to the lower shaft plate.

In an embodiment of the present invention, a guard shell is disposed between the axle, the upper axle plate and the lower axle plate.

In an embodiment of the present invention, a guard shell is disposed at the front fork of the frame.

In an embodiment of the present invention, the front wheel is further provided with a brake clamp, and the brake clamp is connected to a brake grip provided on the pull rod.

Please refer to "Figures 1, 2 and 3", and Figure 1 is a schematic diagram of the appearance of this creation. Figure 2 is a schematic exploded view of the shaft unit of the present creation. Figure 3 is a schematic view of the top view of the creation. As shown in the figure: The steering control structure of the three-wheeled tailgate comprises at least one frame 1, a steering control mechanism 2 and a carrying unit 3.

The front frame 11 is fixed at one end thereof, and the front fork 11 is movably coupled with a front wheel 12 having a transmission pedal 121 on both sides of the front fork 11, and the front wheel 12 is further provided with a brake. a clamping device (not shown), and the other end of the frame 1 is provided with a rotating shaft unit 14 . The two sides of the rotating shaft unit 14 are respectively combined with a rear wheel 15 , wherein the rotating shaft unit 14 further comprises a rear wheel 15 . The combined axles 141 are respectively disposed on the axle 141 and span the axle 1 of the other end of the frame 1 42 and a lower shaft plate 143, and a pivot shaft 144 (shown in FIG. 2) on the upper and lower shaft plates 142, 143 and the frame 1, and the front fork 11 of the frame 1 and the axle 141, A casing (not shown) is respectively disposed between the upper shaft plate 142 and the lower shaft plate 143, thereby utilizing the casing as a protection for personnel and parts.

The steering control mechanism 2 is movably coupled to the frame 1, and includes a sleeve portion 21 (shown in FIG. 1) disposed adjacent to the front fork 11, and a tie rod 22 respectively disposed on both sides of the sleeve portion 21, And connecting the connecting rod 23 of the rotating shaft unit 14 and the pull rod 22 respectively (as shown in FIG. 2), and one end of each connecting rod 23 is connected to the pull rod 22, and the other end is connected to the lower shaft plate 143 of the rotating shaft unit 14.

The carrying unit 3 is disposed on one side of the frame 1 and located between the rotating shaft unit 14 and the tie rod 22, and the carrying unit 3 includes a moving portion 31 disposed on the frame 1 and a moving portion 31. The seat cushion 32 on the top surface and a fixing button 33 of the bottom surface of the moving portion 31 and locked to the frame 1 (as shown in Fig. 1).
