Description

Technical Field

[0001] This utility model relates to the field of children's twist car technology, specifically a children's twist car anti-tipping device. Background Technology

[0002] Children's twist cars are a popular toy among children, also known as rocking cars or children's exercise cars. The main body is mostly made of engineering polypropylene through injection molding, resulting in a stable structure and simple operation. No battery or transmission device is required; relying on centrifugal force and the inertia of human movement, the car moves freely forward and backward by turning the steering wheel left and right. Long-term use can improve children's nerve reflexes and sensitivity, strengthen waist muscles, stimulate acupoints in the feet, and promote healthy growth. Since the steering wheel is mainly operated with both hands, it can stimulate both hemispheres of the brain, promote cerebellar development, and improve children's intelligence.

[0003] Utility model patent CN208931518U discloses a children's twist car, including a frame, handlebars, a pivot, a front wheel assembly, and a rear wheel assembly. The front wheel assembly includes a front wheel frame. The pivot passes through the frame and connects to the handlebars and the front wheel frame. A handlebar fixing member is provided at the upper end of the pivot. The upper end of the handlebar fixing member has a locking protrusion that restricts the downward movement of the pivot and matches a through hole in the frame to form a snap-fit ​​structure. A snap-fit ​​structure is provided between the handlebar fixing member and the handlebar. A front wheel frame fixing member is provided at the lower end of the pivot. A snap-fit ​​structure is provided between the front wheel frame fixing member and the front wheel frame. A bearing cap is provided on the pivot, located above the front wheel frame fixing member and engaging with the through hole in the frame to restrict the upward movement of the pivot. This utility model has the following advantages: simple structure, strong practicality, convenient installation, and easy alignment of the angle between the front wheel frame and the handlebars.

[0004] However, when using this children's scooter, the child sits too far back, causing the overall center of gravity to shift backward, which poses a risk of tipping over during travel. Therefore, a tipping-over prevention device for children's scooters is proposed to solve the aforementioned problems. Utility Model Content
