AI Technical Summary
Existing children's stroller brake systems are mostly single-sided brakes or unconnected, which are difficult to operate. In addition, consumers need to hold the product or follow it at all times in shopping scenarios, and there is a lack of an effective dual-brake structure to ensure safety and convenience.
It adopts the form of one-step dual brake. Through the design of the pedal mechanism and brake mechanism, when the pedal is stepped on, the sliding pin moves along the L-shaped slide groove, the pull wire is relaxed, and the pin seat assembly pops up and inserts into the brake disc hole to achieve synchronous braking of both wheels; when the pedal is lifted, the sliding pin moves upward, the pull wire is tightened, and the pin disengages from the brake disc, allowing the vehicle to move forward.
The stroller has dual-wheel synchronous braking, which ensures simple operation, safety and balance, and meets the needs of convenient use in shopping scenarios.
