Description

Technical Field

[0001] The utility model relates to the technical field of crawler structures, in particular to a crawler structure. Background Art

[0002] A pool robot is a robot used to assist or replace manual cleaning of a pool. It can greatly reduce the burden of manual cleaning and improve cleaning efficiency. Existing pool robots mostly use a crawler mobile mechanism, which can provide good grip when cleaning the bottom of the pool, can walk stably and effectively clean the dirt on the bottom of the pool. However, when the robot needs to climb a wall for cleaning, especially when moving on a smooth wall, the grip of the crawler is slightly insufficient. For example, when moving on materials with low surface friction such as tiles and glass, it is difficult for the robot crawler to provide sufficient traction, which in turn affects the robot's cleaning efficiency on the wall.

[0006] Furthermore, two ends of the groove pass through two sides of the traveling teeth.

[0007] Furthermore, a plurality of partitions are arranged in the groove, and the partitions divide the groove into multiple sections.

[0008] Furthermore, the cross section of the groove is rectangular or trapezoidal.

[0009] Furthermore, the width of the groove is 1 / 4 to 1 / 2 of the width of the ground contact surface of the walking gear.

[0010] Furthermore, the height of the groove is 1 / 5 to 1 / 3 of the height of the traveling teeth.

[0011] Furthermore, the spacing between the traveling teeth is 15 to 50 mm.

[0012] Furthermore, the angle between the side surface of the traveling tooth and the outer surface of the track body is 95-115°.

[0013] Furthermore, the traveling teeth are made of silicone.
