Automatic deceleration safety wheel for buggy

Abstract

The invention relates to the technical field of children products. The utility model discloses an automatic deceleration safety wheel for a buggy. The automatic deceleration safety wheel comprises a supporting shaft and a wheel body movably connected to the exterior of the supporting shaft in a sleeving mode. Wherein a reduction gearbox is fixedly installed in the wheel body, the reduction gearboxis movably connected to the outer portion of the supporting shaft in a sleeving mode, movable sleeving portions of the reduction gearbox and the supporting shaft are rotationally connected and sealedthrough a sealing bearing, and a separation cylinder is fixedly installed on the inner wall of the reduction gearbox and is in a cylinder shape. The reduction gearbox is arranged in the wheel body; the separation cylinder is arranged in the reduction gearbox; the reduction gearbox and the separation cylinder are filled with water; due to the fact that the reduction gearbox and the separation cylinder are filled with water and are communicated through damping holes, when the vehicle speed is too high, the flow quantity of water driven by auger blades is remarkably increased, the passing flow of the damping holes in unit time is limited, the water in the separation cylinder has rotating resistance relative to the auger blades, and then self-deceleration can be effectively achieved.

Description

technical field [0001] The invention relates to the technical field of children's products, in particular to an automatic deceleration safety wheel for children's vehicles. Background technique [0002] Children's vehicles are divided into two-wheeled scooters, three-wheeled and four-wheeled vehicles. Among them, three-wheeled and four-wheeled children's vehicles have two types of foot power and electric power. In daily use, due to children's lack of awareness of danger, when using children's vehicles, they often overturn and fall due to excessive sliding speed, especially in the sprint stage of the downhill section, dangerous accidents are more likely to occur. However, although the upper limit of the rated speed is set for the electric car, it is also prone to the danger of overspeeding and overturning on the downhill section, and these dangers occur more frequently under the care of non-adults. In the case of nursing care, accidents such as overturning and collisions wil...
