Description

Technical Field

[0001] This application relates to a steering wheel structure for a child vehicle with adjustable body position and the child vehicle thereof. Background Technology

[0002] Strollers, especially rideable children's cars, are a popular toy among children and parents. These products typically feature four wheels, a dashboard, a driver's seat, and a steering wheel. Currently, most standard children's cars on the market have a fixed steering wheel design, which has certain limitations: if the interior space is too large, a child sitting in the driver's seat may have difficulty reaching the steering wheel; if the space is too cramped, it will affect the comfort of driving. Therefore, to accommodate children of different ages, parents often need to purchase strollers of multiple sizes.

[0003] To address this issue, some products have attempted to design driver's seats with fore-and-aft adjustment. While this alleviates the problem of insufficient fore-and-aft space to some extent, it still cannot solve the need for height adjustment. As children grow, the increase in leg length can cause their knees to interfere with the steering wheel while driving, affecting the user experience.

[0004] Therefore, it is particularly necessary to design a steering wheel structure that can adjust the body space in both forward / backward and up / down directions. Such a design can make the same stroller suitable for children of more different ages, significantly improving the product's applicability and lifespan.

[0005] Currently available adjustable steering wheel structures are often complex, expensive, and inconvenient to install, thus lacking promotional value. Summary of the Invention

[0026] See Figures 1 to 4 This embodiment provides a child stroller steering wheel structure with adjustable body position, comprising: The steering wheel body 1, universal joint assembly, and transmission component 2 are connected by the universal joint assembly and the transmission component. The steering wheel body also includes a limiting seat with a first connecting portion 3 and a second connecting portion 4 that can only be bent relative to each other. The universal joint assembly includes an upper connecting fork 5, a lower connecting fork 6, and a ten-piece 7 connecting the upper and lower connecting forks. The first connecting portion cooperates with the upper connecting fork to restrict the degree of freedom of the upper connecting fork in the radial direction, and the second connecting portion cooperates with the lower connecting fork to restrict the degree of freedom of the lower connecting fork in the radial direction. The steering wheel also includes a damping structure for creating damping between the first and second connecting portions or for switching between an unlocked and movable state.

[0027] According to the inventive intent of this application, the damping structure includes a locking structure between the first connecting part and the second connecting part that unlocks when movement is required and fixes when fixation is required, and also includes a mechanism in which there is resistance to movement between the first connecting part and the second connecting part, and a large external force is required to overcome the resistance to allow the two to move relative to each other.

[0028] In this embodiment, the first connecting part and the second connecting part are rotatably connected. The damping structure includes a damping tooth 8 disposed on one of the first connecting part and the second connecting part, and a damping part 9 disposed on the other connecting part and engaged between the teeth of the damping tooth to form a damping fit. Under the action of external force, the damping part can disengage from the teeth of the damping tooth. The damping tooth and the damping part are arranged vertically, and gravity causes the damping tooth and the damping part to form a damping fit.

[0029] Preferably, the limiting seat is configured to have a receiving cavity for accommodating the universal joint assembly.

[0030] Preferably, the first connecting portion is configured as an upper cover, and the second connecting portion is configured as a lower cover, with the receiving cavity formed between the upper cover and the lower cover. The upper cover has an upper opening 10 for the upper connecting fork and / or steering wheel body to pass through, and the lower cover has a lower opening 11 for the lower connecting fork and / or transmission component to pass through.

[0031] Preferably, one of the upper cover and the lower cover has a rotating shaft 12 on its side and the other has a slot 13 that mates with the rotating shaft. The width of the slot opening 14 is smaller than the diameter of the rotating shaft.

[0033] Similarly, one of the lower connecting fork and the ten-byte is provided with a pivot, and the other is provided with a slot that mates with the pivot. The width of the slot is smaller than the diameter of the pivot.

[0034] The above structure improves upon the traditional universal joint structure by combining a central plastic cross shaft with upper and lower opening fixed forks, which are then mounted on a limit seat. This results in a simple structure, low cost, and convenient installation, making it a promising candidate for widespread application.

[0035] This utility model also provides a children's stroller, including a stroller body and a stroller steering wheel structure with adjustable body position as described above, wherein the stroller body is fixedly connected to the first connecting part or the second connecting part.
