Technical Field

[0001] This utility model relates to the field of children's vehicle technology, and in particular to a height-adjustable structure for a children's vehicle steering wheel. Background Technology

[0002] An electric children's vehicle is a miniature simulated vehicle designed specifically for children, powered by a battery and driven by an electric motor. It is typically made of plastic and metal, and its appearance mimics real cars, construction vehicles, or cartoon characters. It is equipped with a steering wheel, pedals, switches, and music playback functions. It not only provides driving fun but also helps children develop coordination and a sense of direction in a safe environment. It is primarily suitable for low-speed riding on flat surfaces such as parks and courtyards.

[0003] Existing electric strollers typically have steering wheels with a fixed height, which cannot accommodate the needs of children of different ages and heights. Shorter children may find it inconvenient to operate the steering wheel due to its excessive height, posing a safety hazard; while taller children may experience discomfort due to the need to bend over, affecting their experience. Therefore, we propose a height-adjustable steering wheel structure for strollers to solve these problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1-6 As shown, a height-adjustable steering wheel structure for a children's stroller is disclosed, comprising an electric stroller body 1, a panel 2 fixedly connected inside the electric stroller body 1, a circular frame 3 fixedly embedded in the outer wall of the panel 2, a convex frame 15 rotatably fitted on the outer wall of the circular frame 3, forming a rotatable connection between the circular frame 3 and the convex frame 15, and preventing the convex frame 15 from moving outward, both the outer walls of the convex frame 15 and the circular frame 3 have through holes, the inner walls of the two through holes are rotatably connected to the same steering column 4, the outer wall of the steering column 4 is fixedly fitted with two bearings 5, the outer rings of the two bearings 5 ​​are fixedly connected to the inner walls of the circular frame 3 and the convex frame 15 respectively, the two bearings 5 ​​reduce the frictional resistance between the steering column 4 and the circular frame 3 and the convex frame 15, making the rotation of the steering column 4 smoother and more flexible.

[0024] One end of the steering column 4 has a transmission groove, and the inner wall of the transmission groove is slidably connected to a column 6. The column 6 can slide synchronously with the transmission rod 7 in the transmission groove to ensure that the height adjustment action of the steering wheel body 8 can be stably transmitted. The outer wall of the column 6 is fixedly connected to the transmission rod 7, and one end of the transmission rod 7 is fixedly connected to the steering wheel body 8. The outer wall of the transmission rod 7 has a strip groove 9, and the inner wall of the transmission groove is fixedly connected to two limiting posts 10. The outer walls of the two limiting posts 10 are slidably connected to the inner wall of the strip groove 9. The two limiting posts 10 and the strip groove 9 cooperate to achieve the directional limiting function. By fixing themselves and letting the strip groove 9 slide along them, the rotational freedom of the transmission rod 7 is restricted, leaving only the vertical movement freedom, providing a stable guide for the height adjustment of the steering wheel body 8. The outer wall of the transmission rod 7 has multiple arc-shaped grooves 11 evenly distributed.

[0025] The convex frame 15 has a limiting component inside, which includes a rectangular piece 12. The outer wall of the steering column 4 has a rectangular groove, and the inner wall of the rectangular groove is slidably connected to the outer wall of the rectangular piece 12. An arc-shaped locking post 13 is fixedly embedded in the outer wall of the rectangular piece 12. Both the steering column 4 and the outer wall of the convex frame 15 have rectangular holes, and the inner wall of the rectangular holes is slidably connected to the outer wall of the arc-shaped locking post 13. One end of the arc-shaped locking post 13 is fixedly connected to a lifting block, and one end of the arc-shaped locking post 13 is slidably connected to the inner wall of one of the arc-shaped grooves 11. Each arc-shaped groove 11 corresponds to a height setting. By locking the arc-shaped locking post 13 into different arc-shaped grooves 11, the steering wheel body 8 can be fixed at different heights to meet the needs of operators of different heights or usage scenarios.

[0026] A spring 14 is fitted on the outer wall of the arc-shaped locking post 13. One end of the spring 14 is fixedly connected to the inner wall of the convex frame 15, and the other end of the spring 14 is fixedly connected to the outer wall of the steering column 4. The spring 14 provides a reset elastic force for the arc-shaped locking post 13. The spring 14 can be replaced periodically. When the arc-shaped locking post 13 is pulled up during the unlocking operation, it is compressed and stored to store elastic force. After the lifting block is released, the elastic force is released and pushes the rectangular piece 12 and the arc-shaped locking post 13 to move inward, so that the arc-shaped locking post 13 automatically locks into the arc-shaped groove 11.

[0027] Working principle: When adjusting the height of the steering wheel body 8, the operator first pulls outward on the lifting block fixed to one end of the arc-shaped locking post 13, causing the arc-shaped locking post 13 to compress the spring 14 and disengage from the currently engaged arc-shaped groove 11, thereby releasing the axial locking of the limit assembly on the transmission rod 7. At this time, the operator can pull the steering wheel body 8 up or down, and the steering wheel body 8 drives the column 6 to slide in the transmission groove of the steering column 4 through the transmission rod 7. At the same time, the strip groove 9 fixed on the transmission rod 7 moves along the groove fixed to the steering column 4. The two limiting posts 10 in the transmission groove slide to ensure that the transmission rod 7 and the steering wheel body 8 can only move smoothly in the vertical direction without rotation. When the steering wheel body 8 is adjusted to the target height, the lifting block is released, and the compressed spring 14 pushes the rectangular piece 12 and the arc-shaped locking post 13 to move inward. Under the elastic force of the spring 14, the end of the arc-shaped locking post 13 is locked into the corresponding arc-shaped groove 11, thereby realizing the re-locking of the transmission rod 7 and the steering column 4, thus completing the adjustment and fixation of the steering wheel height.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
