Supporting device, hub module and joint device

Abstract

The invention discloses a supporting device, a hub module and a joint device. The hub module comprises a joint device, a first shaft rod and a second shaft rod; the joint device comprises a first joint piece, a second joint piece, a linkage piece and two inserting pins, wherein the second joint piece is coplanar with the first joint piece and is arranged at an interval, the linkage piece is provided with two slender limiting holes; the first joint piece is provided with a first shaft hole and a first pin hole, and the second joint piece is provided with a second shaft hole and a second pin hole; the two inserting pins penetrate through the first pin hole and the second pin hole and are movably arranged in the two limiting holes in a penetrating mode; the first shaft rod and the second shaft rod penetrate through the first shaft hole and the second shaft hole respectively; the first joint piece can rotate by taking the first shaft rod as the axis, so as to drive the linkage piece to move in the direction perpendicular to the limiting holes through the corresponding inserting pins, so that the other inserting pin pushes the second joint piece to rotate by taking the second shaft rodas the axis. Therefore, the first joint piece and the second joint piece are matched with the linkage piece capable of linearly moving through the two inserting pins, so that the technical effect of synchronously rotating is achieved.

Description

technical field [0001] The invention relates to a support device, in particular to a support device, a hinge module, and a joint device capable of synchronous operation. Background technique [0002] Most of the existing hinge modules are actuated by two sets of stacked tooth pieces meshing with each other, so the existing hinge modules require a large number of tooth pieces, which makes the existing hinge modules difficult to produce. Furthermore, since the existing hinge module uses the above two sets of stacked tooth pieces to engage for power transmission, the center distance between the two shafts respectively passing through the above two sets of stacked tooth pieces will be limited by the tooth sheet construction and cannot be easily adjusted or changed. [0003] Therefore, the inventor feels that the above-mentioned defects can be improved, and Naite devoted himself to research and combined with the application of scientific principles, and finally proposed an inven...
