Description

A front wheel shock-absorbing structure for baby carriage

technical field

The utility model relates to the technical field of baby carriages, in particular to a front wheel shock-absorbing structure for baby carriages, in particular to its mechanical structure.

Background technique

The damping performance of the wheels of existing three-wheeled or four-wheeled strollers is mostly achieved by using rubber tires or vacuum inner tubes. Such a damping range is only suitable for relatively flat roads. When encountering rough roads, the body will appear The obvious bumpy feeling is not conducive to improving the ride comfort.

In view of the above, it is still necessary to further improve the existing shock-absorbing structure of baby carriage wheels, so as to effectively enhance the adaptability of the shock-absorbing structure to rough road surfaces.

Contents of the invention

The purpose of this utility model is to provide a front wheel shock-absorbing structure for baby carriages, which adopts a cantilever-type shock-absorbing system, utilizes the cooperation between the shock-absorbing spring and the cantilever, and when an obstacle is encountered, the shock-absorbing The spring can directly absorb the impact of obstacles on the wheels, and at the same time, the cantilever will deflect and swing backwards, further reducing the impact of obstacles on the car body, effectively solving the bumpy feeling caused by rough roads on the baby carriage, thereby improving ride quality The comfortable feeling overcomes the shortcomings and deficiencies existing in the prior art.

In order to achieve the above object, the technical solution of the utility model is: a front wheel shock absorber structure for baby carriages, including a front wheel bracket, the lower end of the front wheel bracket is movably connected with the upper end of the cantilever base through a rotating mechanism, and the cantilever base One side is connected to one side of the upper end of the wheel cantilever through the rotating shaft. The wheel cantilever swings around the rotating shaft. A shock-absorbing spring is arranged between the cantilever base and the wheel cantilever. The upper end of the shock-absorbing spring is against the top of the hollow inner cavity of the cantilever base. , the lower end of the shock absorber spring is against the other side of the upper end of the wheel cantilever, and the other side of the cantilever base is provided with a protruding protective plate. distribution, and the distribution direction is the same, the lower end of the wheel cantilever is connected with the front wheel of the stroller.

The utility model discloses a shock-absorbing structure for the front wheel of a stroller, which adopts an elastic cantilever mechanism to realize the shock-absorbing effect of the front wheel of the stroller. When the shock spring is compressed, the cantilever will deflect with the rotating shaft as the fulcrum to minimize the impact of obstacles on the upper body. The upper end of the cantilever is placed in the cantilever base, which effectively prevents the swing direction and swing clearance of the cantilever from being limited. The stability and safety of the shock absorbing device are improved, the overall structural design of the shock absorbing structure is reasonable, the concept is ingenious, it has good practicability, and it is easy to be popularized and applied to different models. Compared with the existing technology, it has outstanding substantive properties effect and significant progress.

detailed description

Below with reference to accompanying drawing, the utility model is further described.

The utility model is a front wheel shock-absorbing structure for baby carriages, comprising a front wheel bracket 1, which is different from the prior art in that the lower end of the front wheel bracket 1 is movably connected with the upper end of a cantilever base 3 through a rotating mechanism 2, One side of the cantilever base 3 is connected to one side of the upper end of the wheel cantilever 4 through a rotating shaft 8. The wheel cantilever 4 swings around the rotating shaft 8. A shock absorbing spring 5 is arranged between the cantilever base 3 and the wheel cantilever 4. The shock absorbing spring The upper end of the cantilever base 3 is against the top of the hollow inner cavity of the cantilever base 3, and the lower end of the shock absorber spring 5 is against the other side of the upper end of the wheel cantilever 4, and the other side of the cantilever base 3 is provided with a protruding protective plate 6. The spring 5 is obliquely distributed, and the wheel cantilever 4 is obliquely distributed like the shock absorber spring 5, and the distribution direction is the same, and the lower end of the wheel cantilever 4 is connected with the baby carriage front wheel 7. The obliquely distributed shock-absorbing springs are conducive to improving the buffering effect. When the front wheels of the stroller encounter obstacles or bumpy roads, the direction of the impact force on the wheels is generally oblique. Therefore, in this patent technology, the shock-absorbing springs The installation direction is designed to be oblique, and its purpose is to directly offset the impact of this part of oblique action.

In practice, the lower inner cavity of the cantilever base 3 is hollow, one side of the hollow inner cavity is semi-closed, and the other side of the hollow inner cavity is open. The above structure is beneficial to limit the amplitude and For deflection gaps, the upper end of the wheel cantilever 4 is located in the above-mentioned hollow cavity. This cladding-like connection mode is beneficial to improve the safety factor of the shock absorber system.

The above content is a further detailed description of the utility model in combination with specific preferred embodiments, and it cannot be assumed that the specific implementation of the utility model is limited to the above descriptions. For a person of ordinary skill in the technical field to which the utility model belongs, without departing from the concept of the utility model, some simple deduction or substitutions can also be made, which should be regarded as belonging to the protection scope of the utility model.
