The wheel cover is semi-ellipsoidal.

The brake pads are arc-shaped.

The front of the vehicle body is connected with a handle through a wire rope.

The beneficial effects brought by the utility model are: the utility model has no handle for grasping the direction, and is more compact and easy to carry; the user can drive the rear wheels to drive the scooter forward by stepping on the rear pedal, which is easy to learn, suitable for the public, and safe , Simple and convenient for industrial production; the structure of three wheels and the setting of the brake device make the driving more stable and safe; the front of the car body is also designed with a handle, which can be lifted and pulled, and is easy to carry.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figures 1 and 2, a self-propelled scooter includes a car body, a front wheel, a rear wheel 8, a brake device and a transmission mechanism, the front part of the car body is provided with a front pedal 1, and the rear of the front pedal 1 is provided with a Pedal 3; said front wheel is two, is respectively installed under the wheel cover 2 that is convex shape in front of car body; Rear wheel 8 is one, is installed in the rear of rear pedal 3; Described braking device comprises brake pad 6 And the elastic strip 7, the brake pad 6 is located above the rear wheel 8, the two ends of the elastic strip 7 above the brake pad 6 are respectively connected with the car bodies on both sides of the rear wheel 8, and the top of the brake pad 6 is connected with the elastic strip 7 by screws 5 Described transmission mechanism is positioned at the below of car body, comprises chain 12, sprocket wheel 14, front moving pulley 11, rear moving pulley 15, driving wheel 13 and spring 10, and sprocket wheel 14 is positioned at the rear of front moving pulley 11 and rear moving pulley 15, and chain 12 Bypassing the front pulley 11, the sprocket 14 and the rear pulley 15 in turn, the two ends of the chain 12 are respectively fixed on the vehicle pole below the car body, the front pulley 11 is connected with one end of the spring 10, and the other end of the spring 10 is fixed on the car body On the vehicle bar below, the rear moving pulley 15 is connected with the rear pedal 3 above the car body through a support rod 4, the drive wheel 13 is meshed with the sprocket 14, and the rear wheel 8 and the drive wheel 13 are installed on the same wheel axle superior.

The wheel cover 2 is semi-ellipsoidal.

The brake pad 6 is arc-shaped.

The front of the car body is connected with a handle 9 by a wire rope.

The appearance of the utility model is smooth, fashionable and beautiful, and the image is vivid. It adopts PC plastic car body, PU plastic front wheel, and high-strength steel for the handlebar and brake pads.

When the utility model is in use, one foot steps on the front pedal 1, and the other foot steps on the rear pedal 3. At this time, the support rod 4 connected to the rear pedal 3 drives the rear moving pulley 15 to slide to the front of the car body. The movable pulley 15 drives the chain 12 to move, and then drives the sprocket 14 to rotate, and the driving wheel 13 meshed with the sprocket 14 rotates thereupon, and finally drives the rear wheel 8 that is installed on the same wheel shaft with the driving wheel 13 to rotate forward, so that Whole scooter moves forward; The spring 10 that links to each other with front moving pulley 11 stretches when stepping on rear pedal 3, spring 10 resets when unclamping rear pedal 3, chain 12, front moving pulley 11 and rear moving pulley 15 are also reset. The scooter mainly relies on the pressure of the front foot to change direction. When the scooter needs to turn left, the front foot puts pressure on the wheel cover 2 on the left, and the speed of the wheel on the left side of the front wheel will be lower than that of the right wheel so as to realize the direction change. The scooter is also provided with a braking device, the brake pad 6 on the braking device is connected with the elastic strip 7 by the screw 5, the brake pad 6 is stepped on to increase the friction between the brake pad 6 and the rear wheel 8, and the rear wheel 8 can be stopped. Movement, after the scooter stops, the brake pads 6 are released, and the elastic strip 7 and the brake pads 6 can be reset due to the elastic force of the elastic strip 7. The front of the scooter body is also designed with a handle 9, which can be lifted and pulled, and is easy to carry. During the sliding process, the handle 9 and the wire rope can be wrapped around the bottom of the car body without affecting the use.
