Abstract

The invention aims to provide a constant-force supporting device based on a gear connecting rod assembly. The device comprises a moving platform, a base, the gear connecting rod assemblies, and forcestorage partd; the moving platform is used for placing a borne object; the gear connecting rod assemblies comprise a first gear connecting rod assembly and a second gear connecting rod assembly; the first gear connecting rod assembly and the second gear connecting rod assembly are connected with the moving platform through upper connecting blocks and connected with the base through lower connecting blocks; and the force storage parts are divided into two sets, are connected with the first gear connecting rod assembly and the second gear connecting rod assembly respectively and are used for storing work done by the gravity of the borne object. According to the constant-force supporting device based on the gear connecting rod assembly, the whole structure is symmetrically arranged, the stress condition is good, the output force fluctuation is small, the precision is high, and the device can be used for occasions and fields needing constant force output, such as the realization of constant force in fitness equipment, the realization of a supporting seat of a display, the realization of a buffer shock absorption device and an end executor of a clamp.

Description

technical field [0001] The present application relates to the field of constant force support mechanism, in particular to a constant force support device based on a gear linkage assembly. Background technique [0002] The reaction force produced by the output end of the constant force mechanism is basically constant within a large range of motion input. The current constant force mechanism generally achieves constant force by changing the torque of the linear elastic spring or butterfly spring, or by combining linear elastic springs or butterfly springs in different directions. When the output end moves in the specified direction, The deformation of one spring increases, while the deformation of the other spring decreases, so that the overall reaction force generated at the output end after mutual compensation remains substantially constant. Limited by the complexity and weight of the mechanism, the current constant force mechanism is mostly used in engineering fields such ...
