A baby trolley with automatic braking function

Abstract

The invention discloses a stroller with an automatic braking function. The stroller comprises a frame base, front wheels and rear wheels arranged on the frame base, a bottom support arranged on the frame base, an infant carrier connected with the bottom support, an automatic braking device arranged on the bottom support, and a push rod device connected with the automatic braking device, wherein the automatic braking device comprises a cam mechanism and a link mechanism, the cam mechanism comprises a round rod, a pulley inside and a sliding groove matched with the pulley, the link mechanism comprises a main link and a driven link connected with the main link through a pin, the other end of the driven link is fixed to a hinged support and connected with a flange through the hinged support, and the other end of the flange is arranged in a tooth space of a rear wheel gear. By the adoption of the stroller, the purpose of locking the stroller automatically at any time as soon as people leave can be realized in use, the braking function of the braking device is realized stably and effectively, and the safety of the stroller and infants sitting in the stroller is improved.

Description

technical field [0001] The invention belongs to the technical field of baby strollers, and in particular relates to a baby stroller with an automatic braking function. Background technique [0002] Existing baby trolleys generally have a slipping phenomenon. The so-called "baby stroller slipping" means that the baby stroller is not locked after parking, just like the driver does not pull the handbrake after parking. However, when there is a strong natural wind in the environment, the baby stroller may slip and slide uncontrollably at any time, and the consequences will be unimaginable. Once an accident occurs, it may be fatal. [0003] Although baby strollers currently on the market are generally equipped with foot-operated brake mechanisms, the operation of such traditional baby stroller braking devices is completely passive, and the baby stroller must be locked by the conscious behavior of the promoter. Whether it is safe or not while parking is completely individual. If...

Problems solved by technology

However, the use of this technology will cause the baby carriage to work live, which is a safety hazard in itself, and the winding and placement of circuits, wires and other devices on the baby carriage also greatly increases unsafe factors

At the same time, the existence of solar panels undoubtedly increases the weight of the car body, and when the acceleration sensor detects that the stroller is accelerating and transmits the corresponding signal to finally trigger the brake device, the rolling has already occurred and will produce a certain displacement and sliding. There is still a considerable risk
