[0036] Refer to the following Figures 1 to 4 A children's tricycle provided by the utility model is described.

[0037] Reference Figure 1 and Figure 2 The child tricycle comprises a body 2, a front tube 3, a front wheel 4, a rear wheel steering mechanism limit and position assembly 5, the front tube 3 is rotatably connected to the front part of the body 2, the front wheel 4 is rotatably connected to the front tube 3, a pedal rod 31 is fixedly connected to the front tube 3, and the pedal rod 31 is horizontally arranged along the lateral direction of the body 2. When the child tricycle is in use, a person sits on the body 2, and two feet step on the two ends of the pedal rod 31 respectively, and the person drives the vehicle forward by twisting left and right.

[0038] Reference Figure 1 and Figure 2 The rear wheel steering mechanism includes a rear wheel axle 11, a rotating bracket 12, a roller 13 and a handle 14. The rear wheel axle 11 is horizontal and arranged along the lateral direction of the vehicle body 2, the rear wheel axle 11 is rotatably connected to the vehicle body 2, the rotating bracket 12 and the handle 14 are both arranged on the rear wheel axle 11, and the roller 13 is arranged on the rotating bracket 12.

[0039] Reference Figure 1 and Figure 2 A second connecting member 111 is fixedly provided at both ends of the rear wheel axle 11, and a rotating bracket 12 is provided at both ends of the rear wheel axle 11. Each rotating bracket 12 is provided with a first connecting member 121, and the first connecting member 121 is rotatably connected to the rotating bracket 12, and the first connecting member 121 is detachably connected to the second connecting member 111.

[0040] Specifically, the first connector 121 of this embodiment is a stud, and the axis of the stud is the rotation axis of the rotating bracket 12. The second connector 111 of this embodiment is a connecting sleeve, and the stud is threadedly connected to the connecting sleeve, so as to achieve a detachable connection between the first connector 121 and the second connector 111.

[0041] Optionally, a connecting sleeve can be used as the first connecting member 121, a stud can be used as the second connecting member 111, and the connecting sleeve and the stud can be threadedly connected. A metal pipe can also be used as the first connecting member 121 and the second connecting member 111, and the first connecting member 121 and the second connecting member 111 are connected through a flange to achieve a detachable connection between the first connecting member 121 and the second connecting member 111.

[0042] One roller 13 is rotatably disposed on each rotating bracket 12 , and the axis of the roller 13 is parallel to the axis of the rear wheel axle 11 .

[0043] Reference Figure 1 One end of the handle 14 is connected to the rear axle 11, and the other end of the handle 14 extends toward the front tube 3. One end of the handle 14 of this embodiment is fixedly connected to the rear axle 11, and the handle 14 is provided at both ends of the rear axle 11, so that the person sitting on the vehicle body 2 can operate the handle 14 with both hands.

[0044] Optionally, one end of the handle 14 may be rotatably connected to the rotating bracket 12 , or one end of the handle 14 may be directly fixedly connected to the corresponding first connecting member 121 .

[0045] Reference Figure 3 The limiting assembly 5 includes a first limiting member 51, a second limiting member 52 and a resisting member 53. The first limiting member 51 and the second limiting member 52 are both arranged in a sheet shape. The first limiting member 51 and the second limiting member 52 are both fixedly connected to the vehicle body 2. The first limiting member 51 and the second limiting member 52 are arranged at intervals. The resisting member 53 is located between the second limiting member 52 and the first limiting member 51. The resisting member 53 is arranged in a sheet shape and is arranged perpendicular to the first limiting member 51. The resisting member 53 is fixedly connected to the middle position in the length direction of the rear wheel shaft 11. Optionally, the first limiting member 51, the second limiting member 52 and the resisting member 53 may also adopt a block structure.

[0046] Reference Figure 3 and Figure 4 When the tricycle is not subjected to external forces, the abutment 53 abuts against the first stopper 51. At this time, the bottom end of the stud is tilted away from the vehicle body 2, so that the angle between the axis of the stud and the ground is an acute angle, that is, the rotation axis of the rotating bracket 12 is not perpendicular to the ground. The connecting line between the two connection points of the roller 13 and the rotating bracket 12 coincides with the axis of the roller 13. The gravity of the vehicle body 2 always acts on the two connection points, so that the axis of the roller 13 is always in or tends to be horizontal. Therefore, the axis of the roller 13 needs to be difficult to tilt, and the rotating bracket 12 is difficult to rotate at this time.

[0047] When a person sitting on the vehicle body 2 pulls the handle 14 upward, the other end of the handle 14 drives the rear wheel shaft 11 to rotate until the abutment 53 abuts against the second limit member 52. At this time, the axis of the stud is in a vertical state, that is, the rotation axis of the rotating bracket 12 is perpendicular to the ground, and the axis of the roller 13 is always in or tends to be horizontal. Therefore, the roller 13 can change the forward direction at will, and the children's tricycle can perform tail-swinging drift.

[0048] Furthermore, the handle 14 includes a connecting section 141, a transition section 142 and a driving section 143 which are arranged in sequence, the connecting section 141, the transition section 142 and the driving section 143 are welded, one end of the connecting section 141 is connected to the rear wheel shaft 11, the connecting section 141 and the driving section 143 are arranged at an obtuse angle, and the transition section 142 is arranged in an arc shape. Thus, the shape of the handle 14 itself is more beautiful, and the driving section 143 is nearly parallel to the ground, which is convenient for people to hold the handle 14 while sitting on the vehicle body 2.

[0049] In order to improve the grip of the handle 14, the outer wall of the driving section 143 is provided with an anti-skid layer 144. Specifically, the anti-skid layer 144 is made of a flexible material and can be a rubber sheet bonded to the handle 14 or a rubber sleeve sleeved on the handle 14. In this embodiment, a rubber sleeve is used as an example, and the outer ring of the rubber sleeve is integrally formed with a plurality of anti-skid edges, so that the grip of the handle 14 is more comfortable and has an anti-skid effect.

[0050] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
