Abstract

The invention discloses a bicycle lifting seat post device, which comprises a telescopic casing pipe assembly, a driving device and a rotating telescopic assembly, wherein the telescopic casing pipe assembly comprises an outer casing pipe and a telescopic pipe, and the outer casing pipe and the telescopic pipe are sheathed; the rotating telescopic assembly comprises a rotation piece which contains two different thread parts, and two transmission pieces which are respectively screwed with the two different thread parts of the rotation piece; the rotating telescopic assembly is used for converting relative rotation between the rotation piece and the two transmission pieces into two groups of linear reciprocating motion; since distance between the two transmission pieces is increased or reduced due to conversion movement difference caused by different respective screwing threads of the two transmission pieces, the telescopic casing pipe assembly is driven to elongate and shorten; the rotation piece and the transmission pieces on the telescopic assembly are driven by the driving device to rotate. Compared with the similar prior art, the bicycle lifting seat post device provided by the invention has the advantages of basically same performance and simpleness in manufacture so as to lower production cost.

Description

technical field [0001] The invention relates to the field of bicycle manufacturing, in particular to a bicycle lifter seatpost device. Background technique [0002] The announcement number CN203410544U that I applied to the National Patent Office before is a patent of the same name titled "A Bicycle Lifting Seat Post Device". The threaded pipe (nut) and the threaded rod are converted into linear reciprocating motion through the relative rotation of the threaded pipe and the threaded rod, thereby driving the telescopic sleeve assembly to realize the telescopic movement; it is essentially composed of a set of screw transmission mechanisms, which usually require Add a component that is convenient for the driving device to drive the rotating telescopic assembly to rotate and can support the pressure when the weight of the human body is loaded on it, that is, the component of the "first bearing" in the technical solution of the patent. Since the diameter of the bicycle lifter se...
