Abstract

The invention discloses a lifting seat post device of a bicycle. The lifting seat post device comprises a telescopic sleeve assembly, a drive device and a rotary telescopic assembly. The telescopic sleeve assembly comprises an outer sleeve and a telescopic pipe, wherein the outer sleeve is in sleeve joint with the telescopic pipe. The rotary telescopic assembly comprises a threaded pipe and a threaded rod, wherein the threaded pipe is in threaded connection with the threaded rod; the rotary telescopic assembly conducts telescoping and reciprocating motion through the relative rotation between the threaded pipe and the threaded rod. The drive device is used for driving the threaded pipe and the threaded rod on the rotary telescopic assembly to do relative rotation. According to the lifting seat post device, through the adoption of the threaded pipe and the threaded rod which are in threaded connection, the relative rotation is converted into rectilinear lifting motion. Duo to the action of the threaded connection, the load bearing capacity of the lifting seat post device is higher than that of the conventional hydraulic or pneumatic lifting seat post device. The lifting seat post device has the advantages as follows: the phenomenon of burst of the conventional lifting seat post is prevented; the safety performance of the bicycle is improved; the transmission manner is more stable; the lifting is smoother; the lifting height can be adjusted at will; compared with a mechanical lifting seat post device, the lifting seat post device is free from the limit of lifting nodes.

Description

technical field [0001] The invention relates to the field of bicycle manufacturing, in particular to a bicycle lifter seat post device. Background technique [0002] There are various types of bicycle dropper seatposts, mainly including hydraulic dropper seatposts, pneumatic dropper seatposts and mechanical lock-type dropper seatposts. However, in the prior art, the dropper seatpost device may cause a risk of explosion, causing potential safety hazards, which also reduces the driving safety of the bicycle to a large extent. Contents of the invention [0003] The object of the present invention is to provide a bicycle dropper seat post device to solve the above problems. [0004] In order to achieve the above object, the technical solution of the present invention is achieved in that: [0005] A bicycle lifting seat post device, comprising a telescopic sleeve assembly, a driving device, and a rotating telescopic assembly; [0006] The telescopic sleeve assembly includes ...
