Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0016] This utility model provides an improved steering control mechanism for children's strollers. The technical solution of this utility model is as follows: like Figure 1 - Figure 4 As shown, a children's vehicle wheel steering control mechanism includes: a steering wheel 1, a docking control shaft 2 disposed below the steering wheel 1, the docking control shaft 2 being able to dock with the steering part of the children's vehicle wheel, and a cylindrical control rod installed at the bottom of the steering wheel 1, the control rod being able to pass through the center of the docking control shaft 2. Under normal conditions, the steering of the children's vehicle is electrically controlled, and the wheels are controlled by rotating the electrically controlled docking control shaft 2. This is existing technology, so it will not be described in detail here.

[0017] like Figures 1-4 As shown, the docking structure is set between the steering wheel 1 and the docking control shaft 2 to connect the steering wheel 1 and the docking control shaft 2. The docking structure includes: an indirect shaft 3, a slider 5, a pin 6, a tension spring 7, and a locking groove 14. The indirect shaft 3 is fixedly connected to the bottom of the steering wheel 1. The sliders 5 are symmetrically arranged on the wall of the indirect shaft 3. The pin 6 is fixedly connected to the bottom of each slider 5. The tension spring 7 is fixedly connected to the bottom of each slider 5. The locking groove 14 is symmetrically opened on the top of the docking control shaft 2. The symmetrical pins 6 can be inserted into the symmetrical locking groove 14.

[0018] like Figures 1-4As shown, the indirect shaft 3 is cylindrical, with a circular groove penetrating through its top center. The slider 5 is rectangular, and the insertion post 6 is rectangular. The locking groove 14 accommodates the insertion of the insertion post 6. The docking structure also includes vertical grooves 4, bottom posts 8, slots 9, and limiting posts 10. The vertical grooves 4 are symmetrically arranged within the cavity of the indirect shaft 3, and each vertical groove 4 is rectangular. Half of the bottom of each vertical groove 4 is open. The bottom post 8 is fixedly connected to the bottom of the vertical groove 4. Slots 9 are respectively opened at the bottom of each slider 5. Limiting posts 10 are respectively rotatably set at the top of each vertical groove 4. The vertical groove 4 can accommodate the vertical sliding of the slider 5, and the insertion post 6 can slide from the vertical groove. The bottom opening passes through, the top of the tension spring 7 can be fixedly connected to the bottom of the slider 5, the bottom of the tension spring 7 can be sleeved on the outer wall of the bottom post 8, the slot 9 is a rectangular slot, the limiting post 10 is a semi-cylindrical shape, and cylindrical cylinders are symmetrically fixedly connected on both sides of the limiting post 10. The cylindrical cylinders on both sides of the limiting post 10 can be inserted into the vertical slot 4, and the plane of the limiting post 10 can contact the bottom of the slider 5 at the slot 9. The docking structure also includes a pull groove 11, a misalignment plate 12 and a handle 13. The pull groove 11 is opened at the top of each vertical slot 4, the misalignment plate 12 is slidably connected in each pull groove 11, and the handle 13 is fixedly connected to the outer wall of each misalignment plate 12. In practical use, when it is necessary to change the control mode of the stroller from electric to manual, the handle 13 is pulled outward. At this time, the handle 13 will drive the misalignment plate 12 to slide along the groove 11. At this time, the misalignment plate 12 will drive the rectangular blocks on both sides to slide synchronously. At this time, the springs on the walls of the rectangular blocks on both sides of the misalignment plate 12 will be compressed. Then, as the misalignment plate 12 moves, it will leave the top plane of the limit post 10. At this time, the slider 5 will be pulled downward by the downward force of the tension spring 7. The slider 5 will move downward along the vertical groove 4. The slider 5 will drive the insertion post 6 to insert into the locking groove 14 for docking. When the slider 5 moves downward, it will drive the top plane of the limit post 10 downward. The limit post 10 will rotate at the position. At this time, the plane of the limit post 10 will be flush with the vertical plane in the vertical groove 4, so that the slider 5 slides downward. When the insertion post 6 is inserted into the locking groove 14, the steering wheel 1 is connected to the docking control shaft 2 through the indirect shaft 3. In summary, by setting up a docking structure and using the unlocking slider 5 to drive the insert 6 into the lock groove 14, the indirect shaft 3 and the docking control shaft 2 can be quickly docked. When unlocking the slider 5, there is no need to specifically look for the handle 13, and it will not distract the child in the stroller.

[0019] like Figures 1-4As shown, the pull groove 11 can communicate with the top of the vertical groove 4, the limiting post 10 is located at the connection between the pull groove 11 and the vertical groove 4, the pull groove 11 can adapt to the lateral sliding of the misalignment plate 12, each pull groove 11 has a rectangular groove symmetrically opened in it, each side of the misalignment plate 12 is fixedly connected with a rectangular block that can slide in the rectangular groove of the pull groove 11, each rectangular block on the wall of the misalignment plate 12 is equipped with a spring, the spring can push the rectangular block on the side wall of the misalignment plate 12 toward the vertical groove 4, the bottom of the misalignment plate 12 can contact the plane of the limiting post 10, and the handle 13 is a semi-circular plate; In actual use, pulling any of the handles 13 on each side will cause the corresponding slider 5 to drive the insert 6 into the locking groove 14, so that the docking control shaft 2 and the indirect shaft 3 are docked. In summary, by setting two independently controllable sliders 5 and pins 6, the position of the handle 13 can be accurately pulled regardless of the angle to which the indirect shaft 3 is rotated with the steering wheel 1, thus facilitating the docking of the indirect shaft 3 and the docking control shaft 2.

[0020] Working principle: When the control mode of the stroller needs to be changed from electric to manual, the handle 13 is pulled outward. At this time, the handle 13 will drive the misalignment plate 12 to slide along the groove 11. The misalignment plate 12 will drive the rectangular blocks on both sides to slide synchronously. At this time, the springs on the walls of the rectangular blocks on both sides of the misalignment plate 12 will be compressed. Then, as the misalignment plate 12 moves, it will move away from the top plane of the limiting post 10. At this time, the slider 5 will be pulled downward by the downward force of the tension spring 7. The slider 5 will move downward along the vertical groove 4. The slider 5 will drive the insert 6 to insert into the locking groove 14 for docking. When the slider 5 moves downward, it will drive the top plane of the limiting post 10 downward. The limiting post 10 will rotate at the position. At this time, the plane of the limiting post 10 will be flush with the vertical plane in the vertical groove 4, so that the slider 5 slides downward. When the insert 6 is inserted into the locking groove 14, the steering wheel 1 is connected to the docking control shaft 2 through the indirect shaft 3.

[0021] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
