In some embodiments of the present invention, as shown in fig. 3, the unidirectional wheel set 2 further includes a direction limiting member 22, the direction limiting member 22 includes a ratchet wheel 221 and a pawl 222, the axle 23 is rotatably connected to the circular track 1, the axle 23 is fixedly connected to the road wheel 21, the ratchet wheel 221 is fixedly connected to the axle 23, and the pawl 222 is rotatably connected to the circular track 1;

when the road wheel 21 is rotated in the first direction, the locking end 2221 of the pawl 222 is disengaged from the ratchet wheel 221 so that the road wheel 21 can be rotated in the first direction;

when the road wheel 21 rotates in the second direction, the locking end 2221 of the pawl 222 engages the ratchet wheel 221 such that the road wheel 21 cannot rotate in the second direction.

Specifically, as shown in fig. 3, one end of the pawl 222 is a rotating end, the other end is a locking end 2221, the rotating end of the pawl 222 is rotatably connected with the circular track 1 through a rotating shaft, the pawl 222 is arranged above the ratchet wheel 221, the locking end 2221 of the pawl 222 is kept in contact with the ratchet wheel 221 under the action of self gravity, and the ratchet wheel 221 is provided with ratchet teeth 2211.

When the road wheel 21 rotates in the second direction, the ratchet wheel 221 rotates in the second direction, and the locking end 2221 of the pawl 222 engages with the ratchet teeth 2211 on the ratchet wheel 221, so that the rotation of the ratchet wheel 221 in the second direction is limited, i.e. the road wheel 21 cannot rotate in the second direction, and finally the circular track 1 cannot move backwards.

Alternatively, a sixth elastic member 225 may be further provided between the pawl 222 and the circular rail 1, and the pawl 222 is urged to maintain a state of contact with the ratchet gear 221 by the sixth elastic member 225. Specifically, the sixth elastic element 225 may be a torsion spring sleeved on the rotation shaft, or a spring connected between the pawl 222 and the circular track 1. The sixth elastic member 225 can ensure that the pawl 222 can always keep in contact with the ratchet 221, so that the locking reaction is quicker.

When the road wheel 21 rotates in the first direction, the spoke on the road wheel 21 pushes the insert 223 to rotate towards the side without the limit stop 224, so that the limit end 2232 of the insert 223 can be disengaged from the spoke, and the road wheel 21 can normally rotate. When the road wheel 21 stops rotating, the insert 223 is restored by the elastic force of the sixth elastic member 225 and inserted between the spokes of the road wheel 21. When the road wheel 21 rotates in the second direction, the insert 223 cannot rotate under the action of the limit stop 224, so that the limit end 2232 of the insert 223 remains inserted between the spokes of the road wheel 21, limiting the rotation of the road wheel 21.
