AI Technical Summary

Technical Problem

The lack of an effective over-winding protection mechanism in the existing technology causes the winding motor to continuously drive the winding tube to rotate. Even after the canopy is completely retracted, the motor continues to output torque, resulting in the winding tube being over-wound around the canopy fabric or steel strip. This leads to fatigue damage to the steel strip and shortens the overall service life of the equipment.

Method used

The design employs a friction ratchet single motor. By setting friction plates and pawl mechanisms on both sides of the drive shaft, a friction ratchet mechanism is formed, which limits the excessive winding of the motor, avoids excessive winding caused by continuous motor drive, enhances the balance of power transmission, and extends the service life of the friction plates.

Benefits of technology

It effectively prevents blade tearing and fatigue wear of transmission components, significantly extends the service life of the equipment, improves structural stability and power transmission uniformity, ensures that the blades are flat and wrinkle-free when extended and retracted, and improves the user's sense of smooth operation.

Abstract

This utility model relates to the technical field of outdoor sunshade equipment, specifically to a friction ratchet single-motor aluminum alloy canopy, comprising a drive shaft, a bracket, and a motor. The bracket is disposed on both sides of the drive shaft, and the motor is fixedly connected to the rear side of the bracket. The output end of the motor is fixedly connected to the right side of the drive shaft. Friction ratchet mechanisms are sleeved on both sides of the surface of the drive shaft. This utility model, by setting a drive shaft and by setting friction ratchet mechanisms on both sides of the drive shaft, consisting of friction plate groups (friction plate one, friction plate two, friction plate three, and friction plate four), pawls (pawl one and pawl two), springs, and ratchet discs (ratchet disc one and ratchet disc two), allows a moving plate to limit the movement of the blades after they are wound up.
