Referring to fig. 1 to 4, the present embodiment provides an independent car, which includes a car body 100, a lifting column 200 and a transverse guide 300; the upper section of the lifting column 200 is disposed in the car body 100, and the lower section of the lifting column 200 is movable in the height direction of the car body 100 relative to the upper section of the lifting column 200; the cross rail 300 is foldably disposed at the bottom of the car body 100, and when the cross rail 300 is folded, the extending length direction thereof extends along the length direction of the car body 100; when the cross rail 300 is unfolded, the longitudinal direction thereof extends in the width direction of the car body 100.

Among them, the compartment body 100 is preferably provided in an elongated rectangular structure. The lifting column 200 comprises a guide cylinder and a telescopic rod, and the upper section can be either the guide cylinder or the telescopic rod. The cross rail 300 is preferably a mature rail.

The working principle and the operation method of the independent compartment of the embodiment are as follows:

when the independent carriage is used, the carriage body 100 is lifted from the traction locomotive 400 through the lifting column 200, and then the carriage body 100 is separated from the traction locomotive 400, so that the independent maintenance and inspection of the traction locomotive 400 are facilitated. In addition, the car body 100 independent of the traction vehicle 400 may be directly placed on a horizontal ground, or may be expanded on the original traction vehicle 400.

Optionally, as shown in fig. 2, a transverse push rod 110 is further disposed in the car body 100; one end of the transverse push rod 110 is fixedly connected with the carriage body 100, and the other end of the transverse push rod 110 is connected with the upper section of part or all of the lifting columns 200; the axis of the lateral push rod 110 extends in the width direction or the length direction of the car body 100; the lateral push rod 110 can move the lifting column 200 back and forth between the car body 100 and the outside of the car body 100. In this structure, the transverse push rod 110 can push the lifting column 200 in any horizontal direction, for example, toward both sides of the car body 100, or toward the rear side of the car body 100. Because the lifting column 200 can be hidden in the carriage body 100, after the lifting column 200 is stored, the independent carriage has a more regular and reasonable outer contour, and the integral appearance structure of the independent carriage is favorably formed.

Alternatively, as shown in fig. 1, the number of the lifting columns 200 is even, the lifting columns 200 are oppositely arranged on both sides of the car body 100, and the transverse push rod 110 is used for pushing the lifting columns 200 to move along the width direction of the car body 100. At this time, the lifting columns 200 are disposed at both sides of the car body 100, which is more advantageous for assembling and disassembling the independent car and the traction vehicle 400. Further, only a part of the elevating column 200 may be built in the vehicle compartment body 100.

Alternatively, as shown in fig. 3, the bottom end surfaces of the two side covers 130 in the width direction of the car body 100 are located on the same horizontal plane, and the bottom height of the cross rail 300 is equal to or higher than the horizontal plane. In this case, when the lateral rails 300 are folded, the outer contour of the car body 100 is not extended by the lateral rails 300, and the outer contour is more uniform and compact.

Alternatively, as shown in fig. 1 and 3, the support bar 310 may be foldably installed at the free end of the transverse rail 300. The rollers are beneficial to translation of the extended caravan after expansion. The folding design is more compact when the carriage is retracted.

Optionally, the bottom of the supporting rod 310 is provided with a roller. The rollers are beneficial to translation of the extended caravan after expansion.

Optionally, as shown in fig. 4, the car body 100 is provided with a bottom plate 120, a side plate 160, a rocker 140 and a pushing hydraulic pressure 150; the side plate 160 is hinged with the bottom plate 120, and the pushing hydraulic pressure 150 is fixedly arranged on the lower surface of the bottom plate 120; the rocker arm 140 comprises a horizontal arm 141 and an inclined push arm 142, and the horizontal arm 141 and the inclined push arm 142 are connected at an obtuse angle; the upper surface of the horizontal arm 141 is attached to the lower surface of the side plate 160, one end of the inclined pushing arm 142 connected to the horizontal arm 141 is hinged to the lower surface of the bottom plate 120, and the other end of the inclined pushing arm 142 is hinged to the pushing hydraulic pressure 150. In this structure, the above structure greatly improves the operating efficiency of the independent compartment expansion.

Alternatively, as shown in fig. 4, a groove 1410 is provided on the upper surface of the horizontal arm 141, and the hinge axis of the side plate 160 and the bottom plate 120 is located in the groove 1410. At this time, the groove 1410 may receive the hinge shaft, preventing the caravan from being protruded upward from the floor 120 after being expanded.

Second embodiment:

fig. 5 is a schematic structural diagram of an extended caravan according to a second embodiment of the present invention. Referring to fig. 5, the embodiment provides an expanded recreational vehicle, which includes a traction locomotive 400 and the independent car of the above embodiment, wherein the car body 100 is arranged on a chassis of the traction locomotive 400 in a liftable manner.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art.
