Description

Technical Field

[0001] This utility model relates to the field of bicycle safety seat technology, specifically to an adjustment mechanism for the seat fixing part. Background Technology

[0002] A bicycle, also known as a pedal bike or cyclist, is typically a small, two-wheeled land vehicle. Riders power their bikes by pedaling, making them a green and environmentally friendly mode of transportation. There are many types of bicycles, including single-person, tandem, and multi-person bicycles, which can be used for commuting and travel in an eco-friendly manner. Increasingly, people are also using bicycles as fitness equipment for exercise and cycling trips. Child seats are specially designed for children of different weights and effectively improve children's safety while riding in a bicycle.

[0003] The current publication number CN204355199U discloses a front-mounted child safety seat for electric bicycles, including a U-shaped support frame, a seat, a front guard plate, a handlebar, a guardrail, a connecting rod, and a backrest. The top of the U-shaped support frame is used to place the seat. The front guard plate is vertically installed at the front of the U-shaped support frame, and the top of the front guard plate is horizontally installed with a handlebar. Guardrails are installed on both the left and right sides of the front guard plate. A connecting rod is welded to the rear of the U-shaped support frame, and the connecting rod is detachably installed on the frame of the electric bicycle through a stainless steel clamp. A U-shaped backrest is also provided on the connecting rod. The U-shaped backrest and the guardrail surround the seat in the middle to form a safety seat.

[0004] To address the safety issues, existing technologies employ a U-shaped backrest and guardrail working together. However, this method still faces challenges in installation, as it cannot be tailored to the tilt angle of the bicycle frame, resulting in limited practicality of the device. Utility Model Content
