Problems solved by technology

In this prior art, the mechanism for realizing the expansion and retraction of the expansion and contraction box is relatively complicated, the left and right expansion and contraction boxes cannot be expanded separately, and the expansion and contraction stroke of the expansion and contraction box is relatively small, so the expansion and contraction The width of the box only reaches about half of the width of the main box

Embodiment Construction

[0021] The invention provides an expandable van type vehicle, in particular an expandable van type semi-trailer. Fig. 1 shows the schematic perspective view of the expandable van type semi-trailer in the fully retracted state of the expandable compartment, figure 2 A schematic view showing the front of the expandable van semi-trailer when the expandable compartment is fully expanded. The tractor for towing the expandable van semi-trailer is not shown in FIGS. 1 and 2 . As shown in Figures 1 and 2, the expandable van type semi-trailer has a main compartment and two expandable compartments that can expand and retract along the transverse direction of the main compartment. The width of each expandable box body is slightly smaller than the width of the main box body, and the two expandable box bodies can be nested with each other and can be nested in the main box body. Of course, it is also conceivable to make the width of the expansion and contraction box body smaller. In the ...

Abstract

The invention relates to an extension-type carriage automobile, in particular to an extension-type cab semi-trailer, which comprises a main carriage body and at least an extension-type carriage body which can extend and retract along the transverse direction of the main carriage body. The extension-type carriage body comprises a support assembly used for supporting the extension-type carriage body in the state of stretching at least of parts of the extension-type carriage body and a guiding assembly used for guiding the extension-type carriage body in the process of extending and retracting the extension-type carriage body along the transverse direction of the main carriage body; the guiding assembly comprises at least two racks (28) fixed at the bottom of the extension-type carriage body along the transverse direction of the main carriage body and a connecting shaft (4) arranged at the bottom of the main carriage body in a rotatable way along the longitudinal direction of the main carriage body; the connecting shaft (4) is respectively connected with each rack (28) through a gear (29). The extension-type carriage body of the extension-type carriage automobile of the invention can be reliably extended and retracted.

Description

technical field [0001] The invention relates to an expandable van type vehicle, in particular to an expandable van type semi-trailer. Background technique [0002] A mobile medical facility is known from US 2007 / 0102946A1, which includes an expandable van semi-trailer with a main compartment and two expandable and contractible compartments along the transverse direction of the main compartment. The expansion and contraction compartments are nested in each other and in the main compartment in a fully retracted state. Because the length of the expansion and contraction box is relatively large, for example, even reaching more than 10 meters, and the gap between the expansion and contraction box and the main box is small, for example, only 1 cm, and because the expansion and contraction box has a certain elastic deformation Ability, a slight deviation in the direction of movement of the expandable box during expansion from the main box may cause the expandable box to get stuck ...
