Description

Technical Field

[0001] This utility model relates to the field of sweeping machines, and in particular to a sweeping machine side-sweeping and swing mechanism and a sweeping machine. Background Technology

[0002] With the improvement of economic and technological levels, the application of smart home products is becoming increasingly widespread. Robotic vacuum cleaners are one of the most common products among them.

[0003] When cleaning corners and edges, robotic vacuum cleaners typically require a side-sweeping module. Conventional side-sweeping modules cannot clean 90° corners, creating blind spots. To address these blind spots, some manufacturers have introduced extendable side-sweeping modules. These modules extend and retract via a drive mechanism, eliminating these areas. However, existing side-sweeping modules usually use a worm gear mechanism to drive their extension and retraction. Worm gear mechanisms are space-consuming, requiring a horizontally placed external drive motor, further reducing the vacuum cleaner's internal space. Furthermore, the high reverse thrust of the worm gear mechanism hinders the flexibility of the side-sweeper's extension and retraction, making it difficult to retract when encountering obstacles, resulting in poor stability and low implementation costs.

[0004] Therefore, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content
