As a further embodiment of the present invention, the transmission assembly 1 includes a sleeve 11 and an abutting member, wherein the abutting member is used for the sleeve 11 to rotate by the motor 21 so as to drive the output shaft 100 to keep synchronous.

Further, when the circumferential direction of the output shaft 100 and the driving direction of the motor 21 are reversed, the interference member is released from its synchronization with the sleeve 11. Specifically, in the above-mentioned technical solution, the motor 21 keeps rotating in a single direction, that is, the motor 21 only drives the output shaft 100 to rotate so as to advance the body, and when the rotation direction of the output shaft 100 is opposite to the output direction of the motor 21, the output shaft 100 is separated from the sleeve 11, and the output shaft 100 is separated from the driving of the sleeve 11.

In the above embodiment, the purpose of the predetermined pitch distribution of the convex portions is that when the speed is limited by the speed limiting mechanism 4, the speed is limited by the rotation speed of the output shaft 100 being greater than the transmission speed of the motor 21 under the influence of the acceleration, and the triggering is not instantaneous under the influence of the characteristics of the mechanical structure, so that there is a certain hysteresis, and therefore, when the speed is limited by the speed limiting mechanism 4, the above structure can meet the requirement of the reaction time and the requirement of the condition that the speed limiting mechanism 4 is triggered (the torque force of the output shaft 100 is greater than the maximum torque force of the motor 21). The rotation speed of the output shaft 100 is limited by the speed limiting mechanism 4 to be kept in a state of 0.1km/h-0.3km/h larger than the maximum torque force of the motor 21, and the distance between the convex part on the first ratchet tooth disk 12 and the convex part on the second gear tooth disk 13 is kept in a preset range under the influence of the transmission speed of the motor 21, so that the speed limiting mechanism 4 is contacted with the speed limiting state when the rotation speed of the output shaft 100 is reduced to be lower than the maximum torque force of the motor 21 after the whole body finishes descending, the convex part on the first ratchet tooth disk 12 catches up with the convex part on the second gear tooth disk 13 under the transmission of the motor 21, and the power connection time of the two parts is finished in a very short time.

Specifically, in the above technical solution, the mode that the synchronizer 42 drives the output shaft 100 to couple to the reduction gear set 41 may be that the abutting portion 421 is rotatably mounted and pulled by the second elastic member 422 (torsion spring or tension spring), so that the abutting portion 421 is far away from the ring plate 411, and when the abutting portion 421 is under the action of centrifugal force, the abutting portion 421 is clamped into a plurality of slots formed on the ring plate 411, thereby realizing the technical purpose that the output shaft 100 is coupled to the reduction gear set 41 for speed reduction; or the abutting portion 421 is a cone-shaped truncated cone structure, one end with a smaller radius is rotatably mounted, the other end is connected through a rod body with two hinged ends, and the second elastic member 422 (a tension spring) pulls the rod body, so that the abutting portion 421 is attached to the side wall of the output shaft 100, and when the rod body is subjected to centrifugal force, the rod body rotates the abutting portion 421, so that one end with a larger radius of the abutting portion 421 is abutted to the ring disc 411, thereby realizing the technical purpose that the output shaft 100 is coupled to the reduction gear set 41 to reduce the speed; or a mechanical mechanism with a clutch function, which is well known to those skilled in the art.

As still another embodiment of the present invention, as shown in fig. 2 and 4, the reduction gear set 41 further includes a plurality of planet teeth 412 engaged with the ring gear 411 and an orbital ring gear 413 movably disposed on and engaged with the plurality of planet teeth 412.

It should be noted that, when the rotation direction of the output shaft 100 is opposite to the output torque direction of the motor 21, the abutting portion 421 abuts against the ring plate 411 under the centrifugal force, and does not drive the ring plate 411 to rotate (which belongs to the common general knowledge and is not described in detail).

Furthermore, the technical problem mainly solved by the invention is that the brake system adopts a traditional hand brake system, and even completely depends on the feet of the children to brake. When the body is in a stagnation state, due to the design restriction of the structure, when the body slips backwards, an effective braking system is lacked, so that when the body is in an environment with a certain inclination angle, the vehicle can automatically slip backwards, and in order to solve the problem, the invention further provides the anti-slip mechanism 3 which comprises a movable shifting piece 31 and a blocking part 32, the rotation direction of the output shaft 100 is opposite to the output direction of the transmission assembly 1, and the shifting piece 31 abuts against the blocking part 32 to lock the rotation of the output shaft 100.

As a preferred embodiment of the present invention, as shown in fig. 6, 7 and 8, the anti-slip mechanism 3 further includes a base 33 fixedly installed in the housing 200, the base 33 is formed with grooves 331 distributed in a circumferential array, the dial 31 includes an arc portion 311 and a vertical portion 312, one end of the arc portion 311 is rotatably installed on the groove 331, and is located in the groove 331 by a third elastic member 34 installed in the groove 331; furthermore, the blocking portion 32 is a fixed wheel disc, and has a tooth hole 321 formed on an inner wall thereof, and the vertical portion 312 is urged into the tooth hole 321 by centrifugal force to lock the output shaft 100. Specifically, in the above embodiment, the outer wall of the vertical portion 312 has an arc-shaped surface on one side, and the other side is a vertical surface. When the body slides, the output shaft 100 rotates reversely and drives the shifting piece 31 to turn out of the groove 331 under the action of centrifugal force, and the vertical surface of the vertical part 312 is abutted against the groove 331, so that the output shaft 100 is braked. When the motor 21 drives the output shaft 100 to rotate, the arc-shaped surfaces of the vertical portions 312 sequentially pass through the recesses 331.

It should be noted that, in the above technical solution, the triggering condition of the anti-slip mechanism 3 is that the speed of the output shaft 100 is 1km/h-2 km/h. The accidents caused by the fact that parents cannot respond in time due to the fact that backward sliding speed is too high are avoided.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
