Description

A multifunctional stroller device driven by a motor or a wheel shaft to drive a cradle

technical field

The present invention relates to a stroller, in particular to a multifunctional stroller device with a cradle driven by a motor or a wheel shaft.

Background technique

Baby stroller is a kind of tool cart designed for the convenience of baby’s outdoor activities. There are various types of strollers. Reasonably designed baby carriages will bring certain benefits to children’s intellectual development and protect their brain development. At present, there is no baby carriage that provides the function of automatic cradle specifically in the market.

The current multi-functional baby stroller cannot have both the shaking function and the convenient function of outdoor mobility, and the baby's comfortable ride is obtained by shaking the cradle by hand. Manual shaking is time-consuming and laborious and cannot obtain a stable shaking frequency, and the shaking amplitude and frequency are affected. Different people have different impacts, and comfort and continuity cannot be guaranteed.

Therefore, there is a need for a stroller capable of both travel convenience and automatic shaking function, which is convenient for travel and can use electric drive to obtain a stable cradle amplitude and frequency, so that the baby can obtain a more comfortable ride and protect the child's mind and body development.

Compared with the prior art, the present invention has the following beneficial effects:

The present invention applies the motor-driven crank connecting rod device to the baby carriage, and introduces the clutch and speed control controller to realize the multifunctional mobile baby carriage device driven by the motor instead of the artificial cradle, and solves the problem of unstable amplitude and frequency caused by manual shaking. Disadvantages, save manpower and efficiently bring babies a more comfortable feeling. The device monitors the motor speed in real time. When the speed is too fast, the motor speed controller will reduce the speed to keep the frequency and amplitude of shaking the basket within a comfortable range. It solves the problem of unstable frequency and time-consuming and laborious problems caused by manual shaking, maintains a constant rotation speed of the motor, and can adjust the speed and frequency in real time for different babies, so as to realize the best speed setting according to different individual babies Adjustment greatly improves the applicability, reduces manual time-consuming and laborious operations, and ensures consistent comfort.
