Hydraulic driven synchronizing mechanism of full-automatic multifunctional retractable motor home

Abstract

The invention relates to a hydraulic driven synchronizing mechanism of a full-automatic multifunctional retractable motor home. Slide bar synchronizing mechanisms are arranged below left and right heads of a chassis retractable slideway frame. The slide bar synchronizing mechanisms are respectively connected with slide bars which retract and slide left and right. Each slide bar synchronizing mechanism comprises a synchronous rotary shaft installed in a connecting lug arranged below the retractable slideway frame. A left roller A, a right roller A and a synchronous gear A are installed outside the synchronous rotary shaft under one retractable slideway frame A. A synchronous rack A is installed under the slide bar in the retractable slideway frame A to be engaged with the synchronous gear A. The left and right rollers A are contacted with the lower face of the slide bar. A left roller B, a right roller B and a synchronous gear B are installed outside the synchronous rotary shaft under the other retractable slideway frame B. A synchronous rack B is installed under the slide bar in the retractable slideway frame B to be engaged with the synchronous gear B. The left and right rollers B are contacted with the lower face of the slide bar in the retractable slideway frame B. The slide bar is connected with a cross beam of a side wall board, and the cross beam of the side wall board is driven by a retractable cylinder.

Description

technical field [0001] The invention relates to a fully automatic multifunctional telescopic caravan, in particular to a hydraulically driven synchronous mechanism for a fully automatic multifunctional telescopic caravan. Background technique [0002] Geological exploration, natural resource investigation, or emergency rescue and disaster relief, etc., need to work in the field or temporarily stay. The existing method is to set up tents, which is troublesome. Sanitary conditions are poor in tents on the ground, therefore, people have designed relevant car houses in recent years. The car house needs to expand to both sides when it is in use, and shrinks to the width corresponding to the car when it is not in use. Therefore, the roof, floor, side wall panels and front and rear wall panels of the car house must have a set of telescopic mechanisms, especially the floor and two sides. The expansion and contraction of the side wall panel usually needs to be driven by multiple set...

Problems solved by technology

The car house needs to expand to both sides when it is in use, and shrinks to the width corresponding to the car when it is not in use. Therefore, the roof, floor, side wall panels and front and rear wall panels of the car house must have a set of telescopic mechanisms, especially the floor and two sides. The expansion and contraction of the side wall panel usually needs to be driven by multiple sets of hydraulic expansion cylinders, but the existing hydraulic expansion cylinders do not have a synchronous mechanism, they only expand and contract together under electric control, so there are often inconsistent actions, so that the hydraulic expansion cylinders on one side of the wall panel first Extend or retract, the telescopic cylinder drives the slide rod to extend or retract, but the hydraulic telescopic cylinder on the other side of the wall panel does not keep up, causing the slide rod on the other side to be stuck, affecting the expansion and contraction of the whole vehicle
