Movable platform floor bearing support system

Abstract

The invention discloses a movable platform floor bearing support system which comprises a plurality of transverse tracks, a hydraulic oil cylinder and a metal supporting arm. Each transverse track comprises a square outer metal casing pipe and a square inner metal pipe, wherein the inner pipe can be movably arranged in the outer casing pipe in a sleeved mode, an outer bearing is installed at the outer side end of the outer casing pipe, the periphery face of the outer bearing is in contact fit with the outer bottom face of the inner pipe, an inner bearing is installed at the inner side end of the inner pipe, the periphery face of the inner bearing is in contact fit with the inner upper surface of the outer casing pipe, and a piston rod of the hydraulic oil cylinder is connected with the middle of the metal supporting arm through a pin shaft. The metal supporting arm comprises a fixed end and a movable end, wherein the fixed end is connected with an automobile chassis through a pin shaft, and the movable end is provided with a bearing. When the transverse tracks are unfolded under the power effect, the hydraulic oil cylinder drives the bearing at the movable end of the metal supporting arm to act on the inner pipes of the transverse tracks, and a movable platform floor which is unfolded outwards is supported.

Description

technical field [0001] The invention belongs to the field of automobile manufacturing, and in particular relates to a support system for a movable extended compartment floor. Background technique [0002] At present, many passenger cars or square cabins used for field work or camping all increase the use space of the compartment by adding a movable extended compartment, so that the use function and efficiency of the vehicle can be greatly improved. On the bottom plate of the movable carriage, a telescopic transverse track needs to be installed, and other supporting systems are used to provide support for the unfolded movable carriage. There are many deficiencies in the horizontal rails provided by the prior art, either the load-bearing performance is not enough, or the expansion and contraction is not flexible enough; at the same time, the support for these expanded movable carriages usually needs to be fixed on the ground by installing support legs, which are far from Wi...

Problems solved by technology

There are many deficiencies in the horizontal rails provided by the prior art, either the load-bearing performance is not enough, or the expansion and contraction is not flexible enough; at the same time, the support for these expanded movable carriages usually needs to be fixed on the ground by installing support legs, which are far from Without human assistance, when the ground is uneven, each support leg needs to be adjusted one by one, and the entire installation and operation process is extremely cumbersome
