POWER DEVICE FOR SUPPORTING AUTOMATIC MOVEMENT OF SKIS
Document Type and Number:
WIPO Patent Application WO/2023/029456
Kind Code:
A1
Abstract:
A power device (100) for supporting the automatic movement of skis, comprising a fitting (111) which can be fixed on the skis (110); a connection assembly (112); and a driving assembly (120). The connection assembly (112) connects the fitting (111) and the driving assembly (120) such that the driving assembly (120) and the skis (110) are arranged side by side. The connection assembly (112) is detachable. Thus, the skis (110) withstand most of the weight of the load when bearing weight, while the driving assembly (120) is mainly responsible for movement such as advancing. Therefore, a driving assembly (120) of smaller size and power can be used, or a driving assembly (120) of the same power can be used to provide greater endurance. In addition, the connection assembly (112) may comprise a quick disassembly and assembly connection assembly (200) to achieve the quick engagement and disengagement between the driving assembly (120) and the skis (110).
