Description

Technical Field

[0001] This utility model relates to the technical field of strollers, specifically to a children's rocking stroller. Background Technology

[0002] As a core item for infants and toddlers' daily outings, the convenience and practicality of strollers have become key factors for parents when making purchases. Current strollers primarily focus on pushing and moving, only meeting the basic needs of parents traveling with children. They are functionally limited and lack entertainment and interactive features, failing to meet children's needs for play and movement during outings.

[0003] Currently, children's products with a rocking function on the market cannot move and are limited to fixed indoor areas. The few strollers that attempt to integrate "movement" and "rocking" functions generally have structural defects: First, the transmission system is complex, often using multi-stage linkages or eccentric mechanisms, which are prone to jamming and wear, resulting in poor rocking stability. Second, safety is insufficient, lacking a targeted braking and locking structure, making it easy for accidental movement to occur during rocking, and the seat angle is fixed, failing to adapt to children's sitting posture adjustment needs. Third, operation is cumbersome, requiring additional manual switching to turn the rocking function on and off, resulting in a poor user experience for parents.

[0004] Therefore, there is an urgent need to design a children's stroller that is simple in structure, reliable in transmission, and highly safe, and that combines the functions of pushing and moving and automatic rocking, with a flexibly adjustable seat angle, in order to solve the technical defects of existing technologies such as limited functionality, limited usage scenarios, and insufficient stability and safety.

[0015] The beneficial effects of this utility model are: The children's rocking stroller described in this utility model solves the technical defects of existing children's strollers, such as limited functionality, unreliable transmission, insufficient safety, and low flexibility of use, resulting in significant comprehensive benefits. Its core advantage lies in achieving integrated "pushing-rocking" without the need for an additional power source. When parents push the push lever, the rotation of the rear wheels directly drives the transmission components, causing the eccentric shaft to rotate and naturally produce a smooth back-and-forth and up-and-down rocking motion of the stroller. This simultaneously meets the needs of outdoor outings and children's entertainment, greatly expanding its usage scenarios such as walks in the neighborhood and shopping in malls.

[0016] This utility model's transmission structure adopts a "multi-gear meshing + eccentric shaft" design. The first to sixth gears mesh in stages to transmit power, ensuring high meshing precision and uniform force distribution, effectively preventing jamming. Furthermore, the gears and eccentric shaft are made of high-strength materials with excellent wear resistance, reducing the probability of failure and lowering production and maintenance costs. The rear wheel brake assembly can be locked by pressing a pedal to prevent accidental slippage. The seat is multi-angle adjustable to accommodate children of different ages, and the backrest angle can be adjusted by pressing a button. Overall, it balances practicality, safety, and user experience, making it suitable for various scenarios and possessing high market application value. Attached Figure Description
