[0040] Please refer to Figure 1and 2 An embodiment of the utility model provides a top-expandable RV, comprising a vehicle front 1, a vehicle compartment 2, a lifting roof 3, a lifting tarpaulin 4 and a first driving mechanism 5.

[0041] The locomotive head 1 is used for towing the carriage 2 , and the locomotive head 1 generally includes a cab 6 and a chassis 7 connected to the rear of the cab 6 .

[0042] The carriage 2 is arranged at the rear of the carriage 2 , the carriage 2 is fixed on the chassis 7 , and the interior of the carriage 2 is a space for personnel.

[0043] The top of the carriage 2 is provided with an opening, and the shape of the opening can be flexibly set according to actual use needs, such as being set to a rectangle in this embodiment. It is understandable that the opening can also be set to a circular, oval, other multi-deformed shapes according to use needs.

[0044] It should be noted that the carriage 2 can be selected as a single-layer or multi-layer carriage according to actual use needs. For example, in this embodiment, in order to make the use space in the carriage 2 larger, the carriage 2 is a three-layer lifting carriage 2. It is understandable that the carriage 2 can also be a motorhome carriage 2 with other numbers of layers.

[0045] Combination Figure 3 As shown, in this embodiment, the carriage 2 includes a lower carriage 8, a middle carriage 9, a top cover outer carriage 10 and a plurality of second drive mechanisms 13. The lower carriage 8 is arranged behind the front of the vehicle 1, and the upper end of the lower carriage 8 is open. The upper and lower ends of the middle carriage 9 are both open, and the middle carriage 9 is sleeved on the upper end of the lower carriage 8 and can slide up and down. The top cover outer carriage 10 is sleeved on the upper end of the middle carriage 9 and can slide up and down, and the opening is arranged on the upper surface of the top cover outer carriage 10.

[0046] Here, the upper port of the lower body 8, the upper port and lower port of the middle body 9, and the lower port of the top cover outer body 10 are all rectangular, so that the lower port of the middle body 9 can be stably mounted on the upper port of the lower body 8, and the lower port of the top cover outer body 10 can be mounted on the upper port of the middle body 9.

[0047] In order to prevent rainwater or dust from leaking into the carriage 2, a first sealing structure 14 is provided between the lower port of the middle body 9 and the upper port of the lower body 8, and a second sealing structure 15 is provided between the lower port of the top cover outer body 10 and the upper port of the middle body 9. Both the first sealing structure 14 and the second sealing structure 15 are elastic connecting belts, such as rubber connecting belts. The middle body 9 and the top cover outer body 10 are generally made of lightweight materials, so when the top cover outer body 10 rises, the middle body 9 can also be driven to move upward through the second sealing structure 15.

[0048] In some embodiments, in order to ensure stable vertical movement of the middle body 9, the lower body 8 and the middle body 9 are connected by a plurality of guide members, each of which includes an upper guide block 17 and a lower guide block 16. The upper guide block 17 is arranged on the outer wall of the middle body 9, and the lower guide block 16 is arranged on the inner wall of the lower body 8. The upper guide block 17 and the lower guide block 16 are vertically slidably connected, so that the middle body 9 can slide freely and limit the distance between the outer wall of the middle body 9 and the inner wall of the lower body 8.

[0049] Each of the second drive mechanisms 13 is fixed on the lower compartment 8 and the output end is connected to the top cover outer compartment 10. In this embodiment, the second drive mechanism 13 is an electric cylinder, and the four second drive mechanisms 13 are respectively arranged on the left and right sides of the lower compartment 8 and arranged in a rectangular shape. The four second drive mechanisms 13 can synchronously drive the top cover outer compartment 10 to rise and fall and drive the middle compartment 9 to rise and fall.

[0050] like Figure 4 and 5 As shown, the lifting cover 3 can cover the opening, and one end of the lifting cover 3 is rotatably connected to one end of the opening, and the other end can move freely relative to the other end of the opening. Here, the rear end of the lifting cover 3 is rotatably connected to the rear end of the opening through a hinge, and the front end of the lifting cover 3 can move freely relative to the front end of the opening.

[0051] The lifting tarpaulin 4 is foldable and is disposed at the periphery between the lifting top cover 3 and the opening. The upper end of the lifting tarpaulin 4 is connected to the edge of the lifting top cover 3, and the lower end is connected to the edge of the opening.

[0052] like Figure 6 As shown, in some embodiments, the lifting tarpaulin 4 mainly includes a tarpaulin 22 and a plurality of elastic shrink bands 23. The tarpaulin 22 is arranged around the opening, and the elastic shrink bands 23 are arranged at intervals along the height direction. Each elastic shrink band 23 surrounds the tarpaulin 22 and is circumferentially arranged on the surface of the tarpaulin 22. Under the restraining action of the elastic shrink bands 23, the tarpaulin 22 can be neatly unfolded and stored.

[0053] The shape of the lower end of the tarpaulin 22 is the same as the shape of the opening. In this embodiment, the tarpaulin 22 is in the shape of a triangular prism, the lower end of the tarpaulin 22 is rectangular, the opening is rectangular, and the edge of the lower end of the tarpaulin 22 overlaps and is connected to the edge of the opening.

[0054] In some embodiments, considering that the tarpaulin 22 is exposed to the rain and the sun, the tarpaulin 22 is composed of multiple layers of materials. For example, in this embodiment, it includes four layers of materials, which are a waterproof layer, an inner cloth, a thermal insulation layer and a decorative layer from the outside to the inside. The layers of materials are bonded together with glue, so that the tarpaulin 22 has good waterproof, heat-insulating, anti-aging and thermal insulation effects.

[0055] The first driving mechanism 5 is arranged in the lifting tarpaulin 4. The first driving mechanism 5 can select an electric cylinder. The first driving mechanism 5 is tilted. The first driving mechanism 5 can be rotatably fixed to the other end of the opening, and the output end of the first driving mechanism 5 can be rotatably connected to the lower surface of the lifting top cover 3 to drive the lifting top cover 3 to rise and fall, thereby driving the lifting tarpaulin 4 to unfold and fold.

[0056] In some other embodiments, in order to ensure that rainwater and dust enter the compartment 2 through the opening after the lifting tarpaulin 4 is folded and stored, the lower surface of the lifting top cover 3 is provided with an upper ring beam 18 and an upper sealing ring 20, the upper sealing ring 20 is arranged around the outer wall of the upper ring beam 18, the edge of the opening is provided with a lower ring beam 19 and a lower sealing ring 21, the lower ring beam 19 is arranged around the edge of the opening, the lower sealing ring 21 is arranged around the outer wall of the lower ring beam 19, and the upper end of the lifting tarpaulin 4 is connected to the upper sealing ring 20, and the lower end is connected to the lower sealing ring 21. In this way, the lower ring beam 19 forms a step on the upper surface of the outer compartment 10 of the top cover, which can prevent rainwater from entering. And when the lifting cover falls, the upper ring beam 18 fits with the lower ring beam 19, and the lifting tarpaulin 4 is easily stored inward between the upper sealing ring 20 and the lower sealing ring 21 to prevent the lifting tarpaulin 4 from being exposed.

[0057] The lifting cover 3 can also be extended out of the lifting tarpaulin 4 away from one end of its rotational connection. When the lifting cover 3 covers the opening, the part of the lifting cover 3 extending out of the lifting tarpaulin 4 fits against the top of the carriage 2 to prevent rain and dust from entering the lifting cover 3.

[0058] In order to expand the internal usable space of the carriage 2, the lower body 8 includes a main compartment 11 and a secondary compartment 12 connected to the upper end of the main compartment 11, the main compartment 11 is fixed on the chassis 7, the front part of the secondary compartment 12 extends forward to the top of the cab 6 relative to the main compartment 11, and the middle body 9 is sleeved on the upper end of the secondary compartment 12. Considering that the berth is generally arranged so that the secondary compartment 12 is located in the space above the cab 6, the opening is located above the forward extending part of the secondary compartment 12, and at this time, the opening is just located above the berth, which solves the problem that the space above the berth is extremely narrow and cannot be sat up, and cannot meet the normal living needs of the personnel.

[0059] When the interior usable space of the top-expandable RV needs to be expanded, the lifting cover 3 is driven to rotate and rise by the first driving mechanism 5, and the lifting cover 3 drives the lifting tarpaulin 4 to unfold, forming an expansion space above the opening, so that the usable space in the compartment 2 is increased; after use, the lifting cover 3 is driven to rotate and fall by the first driving mechanism 5, and the lifting cover 3 drives the lifting tarpaulin 4 to fold, and the lifting cover 3 covers the opening to close the opening.
