Description

Technical Field

[0001] The present invention relates to the technical field of carriage equipment, and in particular to a vehicle carriage device with an expandable area. Background Art

[0002] In busy commercial districts, large-scale event sites or tourist attractions, there are often mobile service stalls that provide catering, goods sales, publicity and consulting services. Such stalls are difficult to dismantle, so a relatively common mobile service vehicle has appeared on the market. The service vehicle is equipped with a carriage that can be opened sideways, making the carriage itself a mobile service station for sales, consulting services, etc. However, such carriages are restricted by road regulations, have a limited overall area, and have a small internal space, which is not convenient enough for service. In this regard, a Chinese utility model patent with authorization announcement number CN205632251U discloses a space-expandable carriage and a vehicle containing the same, which discloses a carriage, wherein the bottom of the carriage is provided with a translation mechanism, a superimposed moving mechanism or a connecting rod moving mechanism for moving the facilities in the car along the bottom of the carriage; its structure is relatively traditional, using the board of the side wall of the carriage to flip to form a bottom plate and a top baffle, which people can stand on to increase the usable area, but such carriages still have the following defects:

[0003] It utilizes the flipping of the car side panels to form a bottom plate and an integral upper flap, which increases the usable area. However, the bottom plate has no good support and poor strength. In addition, the space expanded by the car side panels only has a bottom plate and an integral upper flap structure.

When the present invention is unfolded, first, the two support assemblies 43 on the driving mechanism 4 are rotated out from the side opening 42, and the third servo reduction motor 4321 in the support assembly 43 is started to make the lower support strip 433 contact the ground, then the hexagonal nut 318 in the side cover structure 3 is loosened, the support leg 313 is rotated out to a suitable position, and the position of the bottom foot 316 is adjusted, and then the two hydraulic push rods 310 drive the side cover plate 31 to flip out, and then the two power arms 46 in the driving mechanism 4 extend outward to drive the sealing plate 21 to move outward, so that the expansion structure 2 is unfolded. After unfolding, the small hydraulic cylinder 439 in the support assembly 43 drives the upper support strip 432 to press against the bottom surface of the lower first rotating plate 23 and the lower second rotating plate 27 to form a support, and then the personnel walk from the ladder plate 35 on the side cover plate 31 into the interior of the expansion structure 2, and rotate the two side support plates 211 at both ends of the recess 210 to seal the two ends. The expansion structure 2 is then moved to a position where the baffle plate 57 blocks the surface of the ear block 212 on the side support plate 211, and the tension of the high-rigidity spring 511 is used to limit the position, fix the position of the side support plate 211, and complete the expansion of the carriage; the two support assemblies 43 provided in the drive mechanism 4 of the present invention can provide good support for the expansion structure 2, and the upper support strip 432 is used to resist the bottom surface of the lower first rotating plate 23 and the lower second rotating plate 27, and the lower support strip 433 is used to support the ground to ensure the support strength of the carriage after expansion. The expansion structure 2 of the present invention forms a side wall structure through the sealing plate 21, and the upper first rotating plate 22 and the upper second rotating plate 24 are stretched to form an upper shielding structure, and the lower first rotating plate 23 and the lower second rotating plate 27 are stretched to form a bottom plate structure, and then the two side support plates 211 are flipped out to seal the two end positions, so that a closed room can be formed, which increases the usable area. The expansion structure 2 itself is closed and can be used normally under weather conditions such as wind and rain.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
