Caravan horizontal pushing mechanism

Abstract

The invention relates to a caravan horizontal pushing mechanism which comprises a horizontal pushing rod (1) and a sliding rail, wherein the horizontal pushing rod (1) is connected with an expanded bin (2), a sliding rail seat (3) is arranged below the expanded bin (2), and the sliding rail penetrates the sliding rail seat (3). The sliding rail comprises an outer tube (4) and an inner tube (5), wherein the inner tube (5) is sleeved in the outer tube (4), and the outer tube (4) penetrates the sliding rail seat (3). The caravan horizontal pushing mechanism can complete the whole process of the expanded bin of horizontal pushing movement-slantingly downwards movement-slantingly upwards movement-horizontal withdrawing movement under pushing of the single acting force of the horizontal pushing rod by being matched with the effect of a steel ball. The caravan horizontal pushing mechanism leads unfolding and folding movements of the expanded bin to be simple and convenient, leads the expanded bin to achieve the unfolding and folding movements under the condition of the single acting force, and accordingly achieves the purpose of saving energy.

Description

technical field [0001] The invention relates to a mechanical pushing mechanism, in particular to a horizontal pushing mechanism of a recreational vehicle. Background technique [0002] At present, the RVs in the world, as well as some special-purpose vehicles, are equipped with an expansion warehouse structure. The expansion compartment can expand the interior space of the vehicle. When the vehicle arrives at the camp or parks for a rest during the journey, the locking device can be opened to open the expansion compartment to expand the interior space of the compartment and provide the occupants with a spacious sleeping and activity space. After the completion, pull back the expansion box body and combine with the front of the car and lock it, and the vehicle can run normally. The expansion warehouse is generally opened or closed by manpower, and the whole process is very laborious and inconvenient. Even if some expansion bins achieve the functions of unfolding and collaps...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the disadvantages of the existing mechanical structure, such as large energy consumption and not simple and convenient operation process, in opening the expansion compartment, and aims to provide a horizontal pushing mechanism for a caravan that not only saves energy, but also can open the expansion compartment with only a single power.
