Title:
LIFTING PLATFORM
Document Type and Number:
WIPO Patent Application WO/2020/199409
Kind Code:
A1
Abstract:
Provided by the present invention is a lifting platform. The lifting platform comprises a table, an energy conversion device (30) connected below the table and a leg assembly. The energy conversion device (30) is used to convert elastic potential energy into auxiliary energy for lifting the table, and comprises a torsion spring (31), a middle shaft (33) and a transmission (32); a first end of the torsion spring (31) is connected to an input part of the transmission (32); and the middle shaft (33) is connected to an output part of the transmission (32). The rotation speed of the input part is less than that of the output part. The leg assembly is connected to the middle shaft (33). During a process of forward rotation or reverse rotation of the middle shaft (33), the leg assembly is shortened or elongated to cause the table to descend or rise. According to the lifting table of the present invention, elastic potential energy stored by the torsion spring is not completely released during the entire rising process of the table, so that the external force required by the table from an operator is small.
