DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present disclosure.

[0031] like Figures 1 to 7 As shown, a roof space expansion structure in one embodiment of the present invention includes an expansion box 1, a pair of expansion plates 2 and a plurality of support mechanisms 3. A pair of storage slots 101 are symmetrically provided in the expansion box 1. The storage slots 101 can be used to temporarily store small objects to prevent small objects from falling from the expansion box 1. A pair of expansion plates 2 are both slidably provided on the upper end surface of the expansion box 1 and can respectively cover a pair of storage slots 101. A control component is installed on the expansion box 1, and the pair of expansion plates 2 move synchronously under the action of the control component. A plurality of support mechanisms 3 are symmetrically provided at the ports of the storage slots 101 and are connected to the expansion plates 2. When the storage slots 101 are opened, the support mechanisms 3 are in a taut state under the action of the expansion plates 2 to play a supporting role.

[0032] Users can place objects on the expansion board 2 for temporary storage, which can greatly improve the storage capacity of the RV to meet the user's needs for placing objects. At the same time, it can also reduce the space occupied by objects in the RV, ensure the user's range of activities, and improve the user experience to a certain extent.

[0033] If there are many items that need to be temporarily stored, including a variety of small items, the control component can be used to control the synchronous movement of a pair of expansion boards 2 to open a pair of storage slots 101. At this time, the user can store small items in the storage slots 101 to avoid placing small items directly on the expansion boards 2, thereby avoiding the problem of losing them when the RV is moved later. When the storage slots 101 are opened, the multiple support mechanisms 3 are pulled by the expansion boards 2 and are in a tense state, that is, Figure 1The left side of the center diagram illustrates the state. By moving the expansion plate 2, the horizontal area of ​​the expansion box 1 can be increased to accommodate more and larger objects, improving overall storage capacity. At the same time, multiple, taut support mechanisms 3 support objects at the opening of the storage slot 101, preventing them from sinking into the slot 101 and ensuring stable placement of large objects.

[0034] like Figures 1 to 7 As shown, a pair of side walls of the expansion board 2 are fixedly connected with sliders, and the side walls of the storage slot 101 are provided with slide grooves matching the sliders. The sliders move in the slide grooves to limit the moving distance of the expansion board 2 and prevent the expansion board 2 from detaching from the expansion box 1.

[0035] The length of the slide groove is smaller than the opening width of the storage slot 101 to prevent the expansion board 2 from moving excessively, thereby ensuring that the expansion board 2 can stably support the object after moving.

[0036] like Figures 1 to 7 As shown, the control assembly includes a protective cover 201 and a screw 202. The protective cover 201 is fixedly attached to the side wall of the expansion box 1. One of the sliders of the expansion board 2 passes through the side wall of the expansion box 1 and is located within the protective cover 201. The screw 202 is rotatably connected to the protective cover 201 and is threadedly connected to a pair of sliders. When the user needs to move the expansion board 2, they simply rotate the screw 202. The sliders are then threaded to move within the protective cover 201, thereby causing the pair of expansion boards 2 to move synchronously, opening or closing the storage slot 101 simultaneously, making operation more convenient for the user.

[0037] At the same time, by providing the protective cover 201 , the connection between the screw rod 202 and the slider can also be protected to prevent dust from adhering and increasing wear.

[0038] like Figures 1 to 7 As shown, a reinforcing rod 203 is fixedly connected to the expansion plate 2, and a pair of reinforcing rods 203 are centrally symmetrical about the expansion box 1. The length of the reinforcing rod 203 is greater than the distance between the farthest ends of the opening width of a pair of storage slots 101, and a connecting groove matching the reinforcing rod 203 is provided in the expansion plate 2.

[0039] By providing the reinforcing rods 203 , the integrity of the connection between the pair of expansion boards 2 can be strengthened, and the strength of the expansion boards 2 can also be strengthened to ensure that the expansion boards 2 can stably and safely support objects.

[0040] Preferably, the reinforcing rod 203 is an L-shaped structure.

[0041] The expansion board 2 is hinged with a baffle 205. When an object is placed on the expansion board 2, the baffle 205 can be unfolded. Figure 1In the state shown, the baffle 205 is used to block objects to prevent them from falling off the expansion board 2, thereby ensuring the storage stability and safety of the objects.

[0042] Among them, a plurality of holes are provided on the baffle 205. Through the provision of the holes, it is convenient for the user to fix the objects on the expansion board 2 through the connecting rope, which can further increase the safety and stability of the object storage.

[0043] like Figures 1 to 7 As shown, the support mechanism 3 includes a support bar 301, a linkage base 302, a pullback belt 303, a tension spring 304 and a plurality of magnetic rings 305. One end of the support bar 301 is fixedly connected to the side wall of the storage slot 101. The linkage base 302 is connected to one end of the support bar 301 located inside the expansion plate 2, and the diameter of the linkage base 302 is larger than the diameter of the support bar 301. The pullback belt 303 is connected to the linkage base 302, and its length is less than the length of the support bar 301. The tension spring 304 is arranged on the inner side of the expansion plate 2 and surrounds the pullback belt 303. The tension spring 304 is connected to the linkage base 302. A plurality of magnetic rings 305 are evenly connected to the side wall of the support bar 301.

[0044] Preferably, the support bar 301 and the pull-back belt 303 are both made of elastic material.

[0045] When the expansion board 2 moves and is no longer covering the end of the storage slot 101, the support bar 301 is first pulled out of the movable slot 204 and then stretched. When the support bar 301 is pulled to a certain length, the support bar 301 will pull the linkage base 302 to move in the movable slot 204, and the pull-back belt 303 and the tension spring 304 will be subjected to tension. When the pulling force on the support bar 301 is greater than the pulling force on the pull-back belt 303 and the tension spring 304, the linkage base 302 will continue to be pulled and move the movable slot 204 closer to the side of the support bar 301. If the expansion board 2 continues to move at this time, the support bar 301 will be pulled and in a taut state. The support mechanism 3 in a taut state can support the objects at the opening of the storage slot 101 to prevent the objects from sinking into the storage slot 101, thereby ensuring the stability of the placement of large objects.

[0046] When the expansion plate 2 covers the storage slot 101 again, the pulling force on the support bar 301 decreases, and the support bar 301 is stored in the movable slot 204 under the pulling action of the pull-back belt 303 and the tension spring 304, avoiding the support bar 301 from being cluttered.

[0047] like Figures 1 to 7As shown, the expansion plate 2 is provided with a plurality of movable slots 204, each corresponding to a plurality of support bars 301. The linkage base 302, the pull-back belt 303, and the tension spring 304 are all disposed within the movable slots 204. The movable slots 204 are used to accommodate the linkage base 302, the pull-back belt 303, and the tension spring 304. They are also used to accommodate the support bars 301, thereby preventing the support bars 301 from being cluttered.

[0048] like Figures 1 to 7 As shown, a roof space expansion structure according to one embodiment of the present invention further includes a pair of covering mechanisms 4. Covering mechanisms 4 are installed within the expansion box 1 and assist the support mechanism 3 in covering the opening of the storage slot 101. Covering mechanisms 4 include a winding roller 401, a covering curtain 402, a connecting plate 403, and multiple metal core layers 404. The winding roller 401 is rotatably connected to the expansion box 1. The covering curtain 402 is wound around the winding roller 401. One end of the covering curtain 402 is positioned at the opening of the storage slot 101, above the support bar 301, and between the pair of reinforcing rods 203. The connecting plate 403 is connected to one end of the covering curtain 402 located at the opening of the storage slot 101 and is connected to the expansion plate 2 via multiple screws. Multiple metal core layers 404 are connected to the side of the covering curtain 402 closest to the support bar 301 and are attracted to multiple magnetic rings 305.

[0049] The winding roller 401 is used to wind the covering curtain 402, which in turn covers the end of the storage slot 101, thereby sealing the end of the storage slot 101 and preventing small items in the storage slot 101 from being squeezed by large items on the expansion board 2. Furthermore, when the covering curtain 402 covers the end of the storage slot 101, it also provides support for the support mechanism 3, further preventing large items from sinking at the end of the storage slot 101 and ensuring that large items are stored effectively on the expansion board 2. The connecting plate 403 connects the covering curtain 402 to the expansion board 2. The metal core layer 404 is used to attract the magnetic ring 305, so that the covering curtain 402 fits the support bar 301, ensuring that the covering curtain 402 effectively covers the end of the storage slot 101.

[0050] After the small items are stored in the storage slot 101, the user pulls the connecting plate 403 to release the covering curtain 402 from the winding roller 401, and connects the connecting plate 403 to the expansion plate 2 with screws, as shown in FIG. Figure 1The state shown on the right. At this point, the cover curtain 402 covers the end of the storage slot 101. Simultaneously, the metal core layer 404 on the underside of the cover curtain 402 attracts the magnetic ring 305 on the support bar 301, allowing the cover curtain 402 to adhere to the support bar 301 and ensure that the cover curtain 402 effectively covers the end of the storage slot 101. Furthermore, the unfolded cover curtain 402 engages the horizontal section of the reinforcing rod 203, keeping the end of the storage slot 101 relatively sealed, preventing rainwater from entering the storage slot 101 and ensuring the storage of small items.

[0051] The expansion box 1 is equipped with a pair of accommodating chambers 102 and a pair of guide wheels 103. A pair of winding rollers 401 are rotatably connected to the accommodating chambers 102, respectively, and a covering curtain 402 passes around the guide wheels 103. The accommodating chambers 102 are used to store the winding rollers 401 and the covering curtain 402. The guide wheels 103 guide the covering curtain 402, preventing friction between the covering curtain 402 and the expansion box 1, thereby increasing the service life of the covering curtain 402.

[0052] In this embodiment, a return spring is connected between the rotating shaft of the winding roller 401 and the inner wall of the accommodating cavity 102. When the expansion plate 2 covers the storage slot 101, that is, Figure 1 In the state shown on the right, under the action of the rotary spring, the winding roller 401 can roll up the covering curtain 402, so that the covering curtain 402 can be rolled up in the accommodating cavity 102, avoiding the covering curtain 402 from being messy.

[0053] like Figures 1 to 8 As shown, a recreational vehicle in one embodiment of the present invention includes the above-mentioned roof space expansion structure and a carriage 5, and the roof space expansion structure is installed on the carriage 5.

[0054] In summary, the present application utilizes the storage slot 101 to store small items. By enabling the expansion board 2 to slide relative to the expansion box 1, the top area of ​​the expansion box 1 can be increased to accommodate larger items, thereby improving the storage capacity of the expansion box 1. The support mechanism 3 and the cover mechanism 4 cooperate to support the items on the expansion board 2, preventing them from sinking into the storage slot 101, thereby ensuring the safety and stability of item storage.
