A schematic view of a three-wheeled scooter of an embodiment.

Hereinafter, a plurality of embodiments of the present creation will be described with reference to the drawings. For the sake of clarity, many practical details will be explained in the following description. However, it should be understood that these practical details are not applied to limit the creation. That is to say, in the part of this creation part, these practical details are not necessary. In addition, some of the conventional structures and elements are illustrated in the drawings in a simplified schematic manner, and the repeated elements may be represented by the same reference numerals.

Please refer to FIG. 1 and FIG. 2 . FIG. 1 is a schematic diagram showing a three-wheeled scooter 100 according to an embodiment of the present invention, and FIG. 2 is a diagram showing the three-wheeled scooter 100 of FIG. 1 . A partial schematic of the other direction. The three-wheeled scooter 100 includes a frame 110, a handle front tube 120, a front wheel set 130, and a rear wheel set 140.

The frame 110 includes a first end portion 111 and a second end portion 112, and the first end portion 111 and the second end portion 112 are integrally formed. The handle front tube 120 is pivotally mounted to the first end portion 111. The front wheel set 130 is disposed at one end of the handle front tube 120. The rear wheel set 140 is disposed on the second end portion 112, and the rear wheel set 140 includes a wheel body connecting structure 150 and two rear wheels 141. The two rear wheels 141 are respectively disposed on two sides of the wheel body connecting structure 150. The frame 110 further includes a tail 113 that is integrally disposed at the second end 112 and partially covers the wheel connecting structure 150. Therefore, the three-wheeled scooter 100 can be stepped on the empennage 113 of the second end portion 112 of the frame 110 by the user (the figure is not shown) to prevent the user from riding the three rounds of the present creation. When the scooter is 100, the feet are directly stepped on the wheel body connecting structure 150, and the user's foot can be prevented from swinging with the operation of the rear wheel set 140, thereby improving the driving stability and safety of the three-wheeled scooter 100 of the present invention. Sex. Moreover, the integrally formed frame 110 can effectively reduce manufacturing cost and manufacturing time, and can greatly increase the overall structural strength of the three-wheeled scooter 100.

Please refer to FIG. 2 and FIG. 3 , and FIG. 3 is a partial schematic view showing another direction of the three-wheeled scooter 100 of FIG. 1 . In the embodiment of FIG. 2, the wheel body connection structure 150 can include a body 151 and an axle 152. The body 151 is connected to the second end portion 112. The axle 152 is integrally disposed on the body 151, and the two rear wheels 141 are respectively disposed at two ends of the axle 152.
