Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and in particular to a self-balancing three-wheeled electric scooter frame. Background Art

[0002] Currently, the manufacturing process of electric scooters requires guidance, typically achieved by installing a handlebar at the front of the scooter. This handlebar rotates the front wheels, thus adjusting the scooter's direction. However, this structure only allows for hand-held control. While foot-operated scooters adjust direction by changing the frame's tilt angle, this also primarily involves tilting the frame to move the two front wheels back and forth. However, this method, with only the front wheels moving, is not very stable. For example, published patent 2019800151549 discloses a scooter and a method for operating it, which uses foot-operated control. However, because each of the four wheels steers independently, this can easily lead to excessive frame torsion and instability. Therefore, solving the problem of excessive frame torsion and instability when controlling direction on ordinary foot-operated scooters is crucial. Utility Model Content

[0003] The purpose of this invention is to provide a self-balancing three-wheeled electric scooter frame. The inward tilt angle of the front wheel axle rotation is driven by a long connecting rod to the reverse position of the rear support. Under the stress of the frame, it tends to move towards the balance position, reducing the torsional angle of the frame and improving stability. This solves the problem of instability caused by excessive torsional angle of the frame when controlling the direction of ordinary pedal scooters.

[0004] This utility model provides a self-balancing three-wheeled electric scooter frame, including a main frame. Axle seats are provided at both the front and rear ends of the main frame. A front wheel linkage is provided at the front end of the main frame, with front wheels at both ends of the front wheel linkage. A steering shaft is provided at the middle position of the front wheel linkage, and the steering shaft is connected to the axle seats at the front end of the main frame. A rear wheel bracket is provided at the rear end of the main frame, with a rear wheel axle on the rear wheel bracket. The rear wheel axle is connected to the axle seats at the rear end of the main frame. A rear wheel is provided at the tail of the rear wheel bracket. A transmission link is provided between the front wheel linkage and the rear wheel bracket.

[0005] A further improvement is that the transmission link is connected to the rear wheel bracket via a transmission shaft seat, with the front end of the transmission link connected to the right side of the front wheel link and the rear end of the transmission link connected to the left side of the rear wheel bracket.

[0006] A further improvement is that: standing frames are provided on both sides of the main frame, which increases the width of the main frame and increases the standing area.

[0007] A further improvement is that: adjusting screws are provided at both ends of the transmission connecting rod, and the length of the transmission connecting rod can be adjusted by rotating the adjusting screws.

[0008] A further improvement is that a connecting shaft is provided on the rear wheel bracket, and the transmission shaft seat on the transmission link is connected to the connecting shaft, rotating around the connecting shaft as the axis.

[0009] A further improvement is that a front wheel axle seat is provided on the front wheel connecting rod, and the front end of the transmission connecting rod is connected to the shaft inside the front wheel axle seat.

[0010] The beneficial effects of this utility model are as follows: By setting a transmission link between the front wheel link and the rear wheel bracket, the inclination angle of the front wheel link rotation is driven by the transmission link to the opposite position of the rear wheel bracket. Under the stress of the frame, it tends to move towards the equilibrium position, reducing the torsional angle of the frame, improving stability, and improving the smoothness of the scooter's steering. At the same time, by setting the standing frames on both sides of the main frame, the width of the main frame is increased, and the standing area is increased. Attached Figure Description
