Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0037] It should be noted that if there are directional indications (such as up, down, left, right, front, back,...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0038] Please refer to Figures 1 to 8 , the present utility model discloses a motorhome, and an expansion structure of the motorhome is connected to the side or the tail of the motorhome. Through this expansion structure, the space effect of the motorhome during actual use can be effectively improved. At the same time, the expansion structure can be folded. By folding the expansion structure, it is convenient to store the expansion structure and convenient for the motorhome disclosed by the present utility model to move.
[0039] However, it is not limited thereto. The expansion structure can be applied to buildings, container houses, assembled houses, mobile houses, etc. It can be determined according to actual needs.
[0040] In some embodiments, the expansion structure disclosed by the present utility model at least includes a back plate 100, side plates 120, a connecting frame 200, and a top plate 300.
[0041] Please refer to Figures 1 to 8 , the back plate 100 can be coincident with the side or tail panel of the motorhome, or the side panel or tail panel of the motorhome can be used as the back plate 100. A bottom plate 110 is provided on the back plate 100, and the bottom plate 110 and the back plate 100 can be arranged at 90 degrees. Therefore, the side plates 120 and the connecting frame 200 can be arranged on the bottom plate 110. Usually, the back plate 100 is arranged vertically. The bottom plate 110 and the back plate 100 are connected by a plurality of hinges. Therefore, by hinging the bottom plate 110 and the back plate 100 with a hinge, the bottom plate 110 can be unfolded relative to the back plate 100. It should be noted that the maximum unfolding angle of the bottom plate 110 is 90 degrees. So that the side plates 120 and the connecting frame 200 can be arranged on the bottom plate 110.
[0042] The side plates 120 include two, and the two side plates 120 can be arranged in parallel on the bottom plate 110. It is allowed to be provided with guide rails on the back plate 100, and the side plates 120 are rotatably and slidably connected to the guide rails. Therefore, when the expansion structure is in the folded state, the side plates 120 are in a fitting state with the back plate 100. And when the expansion structure is in the unfolded state, the side plates 120 slide along the guide rails and unfold at the ends of the guide rails, so that the two side plates 120 are in a parallel state with each other.
[0043] It should be noted that support plates 140 are hinged on both sides of the bottom plate 110 through hinges. There are two support plates 140, and the two support plates 140 are respectively located on both sides of the bottom plate 110. When the support plates 140 are unfolded, the support plates 140 and the bottom plate 110 are horizontally arranged. At this time, the side plates 120 are allowed to be located on the support plates 140, and a locking connection can be made between the side plates 120 and the support plates 140 through a locking structure.
[0044] [[ID=⑥]]Further, a protection plate 130 is hinged on one side edge of the side plate 120. It can be seen that the protection plate 130 can rotate relative to the side edge. In some embodiments, a sleeve 131 is fixedly connected to one side of the protection plate 130, and the sleeve 131 is fixedly connected to the side plate 120. By providing the sleeve 131 between the side plate 120 and the protection plate 130, the protection plate 130 can rotate relative to the side plate 120.
[0045] In some embodiments, the protection plate 130 is a multi-layer structure. For example, the multi-layer structure of the protection plate 130 at least includes an inner side plate 1301, an outer side plate 1302, and a sandwich plate 1303 disposed between the inner side plate 1301 and the outer side plate 1302.
[0046] Specifically, the inner side plate 1301 and the outer side plate 1302 are PC plates, and the sandwich plate 1303 is made of soft foam material. By setting the inner side plate 1301 and the outer side plate 1302 as PC plates, and the sandwich plate 1303 as soft foam material, the protection plate 130 can be bent.
[0047] In some embodiments, the connecting frame 200 is arranged on the bottom plate 110, and the connecting frame 200 is slidably connected to the bottom plate 110. Specifically, the connecting frame 200 adopts a rectangular frame structure, and the connecting frame 200 can be folded. At the same time, the connecting frame 200 and the bottom plate 110 can be connected through guide rails. For example, it is allowed to be provided with guide rails on the connecting frame 200, and the connecting frame 200 is slidably connected to the guide rails. When the connecting frame 200 slides on the guide rails, the connecting frame 200 can protrude from the edge of the bottom plate 110. By protruding the connecting frame 200 from the edge of the bottom plate 110, the spatial structure of the device in actual use is expanded.
[0048] Furthermore, it is allowable to provide multiple layers of flower racks 210 on the connecting frame 200. The multiple layers of flower racks 210 are telescopically arranged along the horizontal direction on the connecting frame 200. Specifically, the connecting frame 200 and the multiple layers of flower racks 210 are slidably connected through guide rails.
[0049] It should be noted that clamping grooves are respectively provided on both sides of the connecting frame 200, and one side edge of the protection plate 130 is allowable to be clamped in the clamping grooves. Therefore, when the expansion structure is unfolded, the side plate 120 is located on the support plate 140. The protection plate 130 is clamped in the clamping grooves in a bent state. At this time, a region can be constructed among the back plate 100, the side plate 120, the protection plate 130 and the connecting frame 200, and this region is the expansion region.
[0050] In order to improve the actual use effect of the expansion region, a top plate 300 is connected to the back plate 100 in a liftable manner, and side plates 310 are respectively fixedly connected to the side edges of the top plate 300. The top plate 300 is allowable to be an arc-shaped structure so as to guide the rainwater falling on the top plate 300. The actual use effect of the device is improved.
[0051] Meanwhile, the side plates 310 and the top plate 300 can be fixedly connected, and the top plate 300 is allowable to be lifted along with the motorhome or an external lifting mechanism. A shielding plate 320 is connected at the edge of the side plate 310. When the side plate 120 is unfolded, the shielding plate 320 is connected to the upper edge of the side plate 120, and at this time, the shielding plate 320 is horizontally arranged. Through the top plate 300 and the shielding plate 320, the top of the above-mentioned expansion region is shielded. However, the top of the region constructed between the protection plate 130 and the side plate 120 is still lacking protection.
[0052] Therefore, the expansion structure disclosed by the present utility model further allows to include a connecting plate 150. The connecting plate 150 is detachably connected to the top of the protection plate 130, and one side edge of the connecting plate 150 is connected to the shielding plate 320, and the other side edge is connected to the side plate 310. Through the connecting plate 150, the top of the region constructed between the protection plate 130 and the side plate 120 is effectively protected. Thus, the overall protection of the top of the expansion region can be realized.
[0053] To sum up, the present utility model discloses an expansion structure of a motorhome and the motorhome to which it is applied. The expansion structure of the motorhome can effectively increase the usable area during the actual use of the motorhome. At the same time, by setting the expansion structure as a foldable structure, the convenience of the expansion structure can be effectively improved. The expansion structure is movable, has a large space, and is beautiful and unique. The arc-shaped top plate 300 and the arc-shaped protection plate 130 which can be arc-shaped enable the expansion structure to have a small wind resistance and be easy to drain water during use.
[0054] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
[0055] In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel scenarios. Taking "A and / or B" as an example, it includes Scenario A, or Scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
