When the scooter runs on a slope with a certain inclination angle, the anti-tilt wheels can be always in contact with the slope under the action of the spring, and even if the scooter subsequently runs on the slope with a larger inclination angle, the anti-tilt wheels can be always in contact with the slope, so that the scooter can be ensured to run stably and reliably on the slope with the changed inclination angle; regardless of whether the scooter of the utility model runs on a plane or an inclined slope, the anti-tilt wheels move to the lowest side under the action of the spring, and regardless of whether the slope with a small inclination angle or the slope with a large inclination angle is located at a more backward position, the scooter can be ensured to have better anti-tilt function. When the scooter stands still, the anti-tilting wheel can move to the foremost side under the action of the spring, and the distance between the front edge and the rear edge of the whole scooter cannot exceed a set size, so that the scooter is more compact in structure.

Preferably, a limiting structure used for limiting the excessive upward or downward movement of the anti-roll wheel is arranged between the fixed piece and the movable piece. The limit structure is arranged, so that the stability and the reliability of the scooter are improved when the scooter is used.

Preferably, the limiting structure comprises a limiting groove and a limiting bulge, the limiting groove is arc-shaped and is arranged on the moving part, and the limiting bulge is fixed with the fixing part and extends into the limiting groove.

As preferred, the articulated department of second is equipped with the axial region, both ends are equipped with first spacing portion and the spacing portion of second respectively about the axial region, mounting and moving part are located between first spacing portion and the spacing portion of second, mounting and moving part all are equipped with the shaft hole that runs through in order to supply the axial region to pass through, the cover is equipped with the axle sleeve on the axial region, the axle sleeve is including stretching into the first ring portion in the shaft hole and being located the second ring portion between mounting and the moving part. Through setting up the axle sleeve to reduce the wearing and tearing between stationary part and moving part, and make the relative slip between stationary part and moving part more smooth and easy.

Preferably, the front end of the spring is connected with the fixed part and forms a first connection position, the rear end of the spring is connected with the movable part and forms a second connection position, the second connection position is located in the middle of the movable part along the front-rear direction, and the second connection position is always higher than the first connection position. The setting is in order to guarantee to exert enough strength to preventing inclining the wheel in the time to avoid the spring to be bigger to the pulling force of moving part, in order to avoid the mounting and the car of riding instead of walk that is fixed mutually with the mounting to receive bigger power, in order to guarantee the structural strength of car of riding instead of walk.

Preferably, the first connection is adjacent the leading edge of the fastener. The arrangement is such that the spring can be arranged longer to ensure the tension of the spring on the movable part.

The utility model has the advantages of improving the anti-tilt effect of the scooter and enabling the scooter structure to be more compact.
