The thread directions at both ends of the two first threaded rods are opposite. Moving blocks are symmetrically threadedly sleeved on the first threaded rods. Support rods are rotatably installed on the upper surfaces of the moving blocks. One end of each support rod away from the fixed frame is rotatably connected to the lower surface of the lifting frame. The moving blocks are horizontally slidably installed in the rectangular grooves. A transmission component is provided on the side of the fixed frame for driving the two first threaded rods to rotate simultaneously.

Specific implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Refer to Figures 1-12 , a motorhome with an expandable space on the roof, including a motorhome body 1. A rectangular fixed frame 2 is fixedly installed on the top of the motorhome body 1. A placement plate 3 is fixedly installed inside the fixed frame 2. A rectangular lifting frame 4 is provided directly above the fixed frame 2. A rectangular folding cloth 5 is fixedly installed between the lifting frame 4 and the fixed frame 2. The fixed frame 2 is fixedly installed on the roof of the motorhome. An item storage space, that is, the roof space, is formed among the fixed frame 2, the lifting frame 4 and the folding cloth 5. Sundries are placed on the placement plate 3, and the folding cloth 5 wraps the sundries inside to prevent the sundries from falling off the roof of the vehicle.

[0022] Rectangular grooves are opened on both the front and rear sides of the fixed frame 2. Two first threaded rods 6 are horizontally rotatably installed in the two rectangular grooves. The thread directions at both ends of the two first threaded rods 6 are opposite. Moving blocks 7 are symmetrically and threadedly sleeved on the first threaded rods 6. Support rods 8 are rotatably installed on the upper surfaces of the plurality of moving blocks 7. One end of each of the plurality of support rods 8 away from the fixed frame 2 is rotatably connected to the lower surface of the lifting frame 4. The moving blocks 7 are horizontally slidably installed in the rectangular grooves. A transmission assembly for driving the two first threaded rods 6 to rotate simultaneously is provided on the side of the fixed frame 2.

[0023] In the initial state, the distance between the fixed frame 2 and the lifting frame 4 is the smallest. The strut 8 is in a horizontal state and is located between the fixed frame 2 and the lifting frame 4. When it is necessary to expand the roof space of the vehicle, the two first threaded rods 6 are driven to rotate simultaneously through the transmission assembly. Since the thread directions at both ends of the first threaded rod 6 are opposite, during the rotation of the first threaded rod 6, the two moving blocks 7 will be driven to move away from each other in the moving grooves. When the two moving blocks 7 move away from each other, the lifting frame 4 will be driven to move vertically downward through the strut 8. At this time, the space between the folding cloths 5 becomes larger, thereby changing the storage space of the roof of the vehicle, effectively expanding the roof space of the RV, providing a larger space for storing sundries, solving the problem of insufficient space when the user carries items, and improving the practicality of the RV.

[0024] On the upper surface of the lifting frame 4, two cover plates 9 are symmetrically and slidably installed through a sliding assembly. The two cover plates 9 can be locked through a locking assembly. When sundries are stored in the roof space, the two cover plates 9 can be driven to approach each other, and then locked through the locking assembly. The two cover plates 9 can block the upper part of the lifting frame 4, thereby closing the roof space and effectively preventing rainwater from entering the roof space and wetting the sundries.

[0025] The transmission assembly includes a rotating rod 11 horizontally rotatably installed at one end of the fixed frame 2 through a mounting block 10, two first bevel gears 12 respectively fixedly installed at one end of the two first threaded rods 6, two second bevel gears 13 respectively fixedly installed at both ends of the rotating rod 11, and a driving component for driving the rotating rod 11 to rotate. The two first bevel gears 12 are respectively meshed with the two second bevel gears 13. The driving component includes a driving motor 14 fixedly installed at one end of the fixed frame 2, a first straight gear 15 fixedly installed at the output end of the driving motor 14, and a second straight gear 16 fixedly sleeved on the middle part of the rotating rod 11. The first straight gear 15 is meshed with the second straight gear 16.

[0026] When it is necessary to drive the two first threaded rods 6 to rotate simultaneously, the driving motor 14 is started to drive the first straight gear 15 to rotate. Since the first straight gear 15 is meshed with the second straight gear 16, the rotating rod 11 can be driven to rotate through the transmission relationship between the first straight gear 15 and the second straight gear 16. When the rotating rod 11 rotates, the second bevel gears 13 at both ends of the rotating rod 11 can be driven to rotate simultaneously. Since the first bevel gear 12 is meshed with the second bevel gear 13, the two first threaded rods 6 can be driven to rotate simultaneously through the transmission relationship between the first bevel gear 12 and the second bevel gear 13.

[0027] A waterproof cover 17 is fixedly installed between the top of the RV body 1 and the fixed frame 2. The transmission assembly is located inside the waterproof cover 17. The waterproof cover 17 covers the transmission assembly, which can prevent rainwater from entering the driving motor 14, play a role in protecting the driving motor 14, and extend the service life of the driving motor 14.

[0028] Both ends of the lifting frame 4 are horizontally provided with moving grooves. The sliding assembly includes two sliders 18 respectively and fixedly installed at both ends of the cover plate 9. One ends of the two sliders 18 are respectively horizontally slidably installed in the two moving grooves. At the positions near one end of the cover plate 9 on the upper surfaces of the two cover plates 9, card slots 19 are respectively opened. At one end of each of the two cover plates 9, positioning holes 20 communicating with the card slots 19 are opened. The locking assembly includes a U-shaped clamping block 21 and two screws 22. Threaded holes are opened at both ends of the clamping block 21. The two ends of the clamping block 21 are respectively inserted into the two card slots 19. The threaded holes opened in the clamping block 21 are aligned with the positioning holes 20. One end of the screw 22 passes through the positioning hole 20 and is threadedly inserted into the threaded hole.

[0029] The two sliders 18 are symmetrically and fixedly installed on the cover plate 9. The two sliders 18 respectively slide in the moving grooves opened at both ends of the lifting frame 4. Thus, the cover plate 9 is slidably installed on the lifting frame 4. When it is necessary to close the roof space, the two cover plates 9 are driven to approach and contact each other. Then, the two ends of the clamping block 21 are respectively inserted into the card slots 19 opened on the two cover plates 9. When the two ends of the clamping block 21 are completely inserted into the card slots 19, the threaded holes opened in the clamping block 21 are just aligned with the positioning holes 20. Then, a tool is used to insert one end of the screw 22 into the positioning hole 20 and threadedly insert it into the threaded hole. The screw 22 can prevent the clamping block 21 from falling off the two cover plates 9, and the clamping block 21 can prevent the two cover plates 9 from separating, thereby locking the two cover plates 9 together.

[0030] Installation grooves are respectively opened on the opposite sides of the two cover plates 9. A sunshade 23 is slidably inserted in the installation grooves. One end of the cover plate 9 is provided with an extension assembly for driving the sunshade 23 to move. The sunshade 23 can play a role in shading. When the RV is camping, the two cover plates 9 can be driven to move away from each other. Then, the extension assembly drives the sunshade 23 to move in the installation grooves, so that the sunshade 23 extends out from one side of the cover plate 9. Users can sit under the cover plate 9 and the sunshade 23 to play. The extended sunshade 23 and the cover plate 9 can play a role in shading during the camping process, greatly improving the user experience.

[0031] The extension assembly includes a second threaded rod 24 horizontally and rotatably installed at one end of the cover plate 9, a driving block 25 threadedly sleeved on the second threaded rod 24, a support rod 26 fixedly installed on the driving block 25, and an adjusting block 27 fixedly installed at one end of the second threaded rod 24. The side surface of the driving block 25 is in sliding contact with one end of the cover plate 9. One end of the support rod 26 away from the driving block 25 is fixedly connected to the side surface of the sunshade 23.

[0032] The rotatable adjusting block 27 drives the second threaded rod 24 to rotate. Since one side of the driving block 25 is in sliding contact with one end of the cover plate 9, during the rotation of the second threaded rod 24, it will not drive the driving block 25 to rotate. Instead, under the action of the thread of the second threaded rod 24, it will drive the driving block 25 to move towards the sunshade 23. During the movement of the driving block 25, it can drive the sunshade 23 to move away from the cover plate 9 through the support rod 26, so as to extend the sunshade 23 from one side of the cover plate 9.

[0033] Metal top rods 28 are symmetrically and rotatably installed at one end of the fixed frame 2. A magnet 29 is fixedly installed at the middle part of one end of the fixed frame 2. Positioning blocks 30 are fixedly installed on the lower surfaces of the two cover plates 9. Limiting grooves 31 are opened on the two positioning blocks 30. One end of the metal top rod 28 can be inserted into the limiting groove 31. When the sunshade 23 extends from one side of the cover plate 9, the metal top rod 28 can be rotated, with one end of the metal top rod 28 facing the positioning block 30 and inserted into the limiting groove 31. At this time, the metal top rod 28 is in an inclined state and can support the cover plate 9, so as to ensure that the cover plate 9 and the sunshade 23 can stably play a sunshading role. When the sunshade 23 is not in use, it is stored in the installation groove opened on one side of the cover plate 9. At the same time, the metal top rod 28 is rotated, and one end of the metal top rod 28 is brought into contact with the magnet 29, and the metal top rod 28 and the magnet 29 are adsorbed together by magnetic force, so as to store the metal top rod 28 at one end of the fixed frame 2.

[0034] A plurality of reinforcing ribs 32 are fixedly installed inside the fixed frame 2. The plurality of reinforcing ribs 32 are all fixedly connected to the placement plate 3. A ladder 33 is installed on the trunk of the RV body 1. The reinforcing ribs 32 can increase the strength of the placement plate 3 and the fixed frame 2, avoiding the collapse of the RV roof due to excessive storage of sundries. The ladder 33 can facilitate users to climb onto the roof to store luggage.

[0035] In the present invention, when it is necessary to expand the roof space, the transmission assembly drives the two first threaded rods 6 to rotate simultaneously. Since the thread directions at both ends of the first threaded rod 6 are opposite, during the rotation of the first threaded rod 6, it will drive the two moving blocks 7 to move away from each other in the moving grooves. When the two moving blocks 7 move away from each other, they will drive the lifting frame 4 to move vertically downward through the support rod 8. At this time, the space between the folding cloths 5 becomes larger, thereby changing the storage space on the roof, effectively expanding the roof space of the RV, providing a larger space for placing sundries, solving the problem of insufficient space when users carry items, and improving the practicality of the RV.

[0036] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
