An automatic deceleration safety wheel for a children's car

Abstract

The invention relates to the technical field of children's products, and discloses an automatic deceleration safety wheel for children's vehicles, which includes a support shaft and a wheel body movably socketed outside the support shaft. A reduction box is fixedly installed inside the wheel body. The reducer box is movably socketed on the outside of the support shaft, and the movable socket part of the reducer box and the support shaft adopts sealed bearings to achieve rotational connection and sealing. The inner wall of the reducer box is fixedly installed with a partition cylinder, and the partition cylinder is a cylinder type. In the present invention, a deceleration box is arranged in the wheel body, a partition cylinder is set in the deceleration box, and water is filled in the deceleration box and the partition cylinder. When it is too fast, the flow of water driven by the auger blades is significantly increased, and the flow rate per unit time of the damping hole is limited, so that the water in the separation cylinder has rotational resistance relative to the auger blades, and thus can effectively realize self-deceleration.

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...
