Document Type and Number:
WIPO Patent Application WO/2024/065342
Kind Code:
A1
Abstract:
Disclosed in the present invention are a telescopic torsion joint structure and a photovoltaic panel cleaning robot. The torsion joint structure comprises: an outer rod body, which has an axially extending first hole and a radially extending second hole; and an inner rod body, which has one end inserted into the first hole and forms a gap with a wall of the first hole, and a connecting pin, wherein the inner rod body is provided with a third hole corresponding to the second hole, the connecting pin passes through the second hole and the third hole, and one of the second hole and the third hole is a waist hole having a long side parallel to the axis of the rod body where the waist hole is located. In the robot, by means of the telescopic torsion joint structure, a wheel axle is connected to a transmission rod, and/or a brush core shaft is connected to a brush support shaft. Using the telescopic torsion joint structure enables the transmission rod and/or the brush to smoothly twist along with the cleaning robot, and compensates for the change in spacing at two ends of the cleaning robot twisting in opposite directions.
