After the folding is completed, the handlebar 201 can be directly held, and the entire electric scooter can be towed by dragging the two driven wheels 202 at this time, thereby avoiding the laborious and difficult handling of the folded electric scooter by manual handling The problem. When the towing is stopped, the two driven wheels 202 and the balance support wheel 315 can also be used to form three-point support on the ground, so that the entire folded electric scooter can be placed in a stable state at any time.

After the vehicle is folded, the upright balance pressure blocks 316 on the left and right sides of the front end of the first connecting rod 304 press against the top surface of the upper balance bar 206 correspondingly, so that the two driven wheels 202 cannot swing up and down, ensuring that The vehicle will not tip over when parked upright.

When the vehicle is unfolded, lift the lever 312 at the rear end of the hook 310 to disengage the locking bar 309 from the hook 310, and the electric scooter moves in the reverse direction according to the folding process to directly unfold the body. After deployment, the deployment lock lever 313 is turned downward around the pin shaft at the connection between the deployment lock lever 313 and the middle portion of the first link 304 under the action of the spring. 314 hooks the unfolding lock lever 15 to ensure the structural stability of the foldable electric scooter in the unfolded state.

The foldable towable electric scooter of the present invention has the following advantages:

1. The scooter of the present utility model adopts an inverted three-wheel structure, and the vehicle has good cornering and anti-sideslip ability, which is safer than a two-wheeled vehicle;

2. The shaft column body 10, the first connecting rod 304, the second connecting rod 305 and the third connecting rod 306 constitute a four-bar linkage mechanism, the second connecting rod 305, the third connecting rod 306, the fourth connecting rod 307 and the fifth link 308 to form another four-bar linkage. When the vehicle is folded, the adjacent second linkage 305 and the fourth linkage 307 can be folded and turned over by more than 180 degrees, which overcomes the independent four-bar linkage. The technical problem that the front and rear links cannot be turned over at a large angle, so that the body of the electric scooter is folded above the wheels, the volume is greatly reduced after folding, and the floor area occupied during storage is small, which is convenient for carrying and storage;

3. When the electric scooter is folded, the driving wheel 301 correspondingly enters between the two driven wheels 202, the three wheels are side by side, and the body is on the top. Larger wheels can be selected. After folding, the storage area is still small. It can ensure that the vehicle has a good passing ability;

4. After being folded, the front two driven wheels are used for towing, the resistance is very small, and it can be carried as convenient and labor-saving as a drag box. Therefore, it is still very convenient to carry with a larger battery, and has a large continuation ability.
