[0001] The utility model relates to the technical field of recreational vehicles, in particular to a pull-out bed mechanism dedicated to recreational vehicles. Background Art

[0002] An RV, also known as a home on wheels, combines the functions of a house and a car, but its attribute is still a car. It is a movable type of vehicle with the basic facilities necessary for a home. It can be parked at will on beaches, lake shores, meadows, hillsides and forests far away from the city, while still having an urban lifestyle.

[0003] In the prior art, a Chinese patent with publication number CN115230570A discloses a pull-out bed-convertible deck specifically for RVs. The user activates the electric telescopic rod 19 to apply a thrust to the support plate 21 through the push plate 20, so that the fixed plate 1 23 and the fixed plate 25 are both located above the table 28, and the bed board 13 is pulled out to transform the deck into a bed.

[0004] However, the above structure is relatively complex and inconvenient for users to use and adjust. In addition, since the space in the RV itself is relatively small, the set table not only occupies the activity space between the seats, but also the seats themselves have no storage function, further reducing the utilization rate of the space in the RV. To this end, we propose a pull-out bed mechanism specifically for RVs. Utility Model Content

[0005] In view of the fact that the beds in existing RVs are not convenient for users to use and adjust, and since the space in the RV itself is relatively small, the installed table not only occupies the activity space between the seats, but the seats themselves also have no storage function, further reducing the insufficient utilization rate of the space in the RV. The utility model provides a pull-out bed mechanism specifically for RVs, which has the advantages of simple structure and convenient operation by users, and at the same time greatly improves the utilization rate of the space in the RV, thereby solving the problems raised in the above-mentioned background technology.

Specific implementation manner

[0021] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a pull-out bed mechanism for a motorhome, including support bases 4 arranged symmetrically, accommodating cavities 13 are respectively opened on the adjacent sides of the support bases 4, and a plurality of first drawers 5 and second drawers 12 are slidably connected in the accommodating cavities 13. As Figure 4 , 5 shown, there are at least two accommodating cavities 13, and a second partition 15 is vertically arranged in one accommodating cavity 13, and the second drawer 12 is slidably connected to the second partition 15. A first partition 14 is horizontally arranged in the other accommodating cavity 13, and the first drawer 5 is slidably connected to the first partition 14. The arranged first drawers 5 and second drawers 12 can meet the storage of items with different volumes, effectively increasing the utilization rate of the space in the motorhome. When in use, in order to facilitate the user to pull the drawers, through grooves 18 are respectively opened on the second drawer 12 and the first drawer 5.

[0023] As Figure 2 , 3 shown, a rectangular frame 3 is fixedly connected to the top of the support base 4. Support plates 2 are fixedly connected to the tops of the mutually remote sides of the rectangular frame 3, and a cushion 1 is arranged on the adjacent side of the support plates 2. U-shaped frames 7 are slidably connected to the adjacent sides of the rectangular frame 3. A plurality of second cross plates 19 are equidistantly connected in the rectangular frame 3, and a plurality of first openings 11 are equidistantly penetrated through the adjacent sides of the rectangular frame 3. The first openings 11 and the second cross plates 19 are arranged alternately. The opening of the U-shaped frame 7 faces the rectangular frame 3. A plurality of columns 9 are vertically connected to the bottom of the side of the U-shaped frame 7 far from the rectangular frame 3, and a plurality of first cross plates 8 are equidistantly connected in the opening of the U-shaped frame 7. The two sides of the U-shaped frame 7 and the first cross plates 8 are slidably connected in the first openings 11.

[0024] In summary, when the pull-out bed mechanism for the RV is in use, as Figure 2 , 3 shows, a reciprocating horizontal sliding is carried out between the U-shaped frame 7 and the rectangular frame 3, driving the first cross plate 8 to move within the first opening 11. And because the second cross plate 19 and the first cross plate 8 are staggeredly arranged, the stability of the support frame formed between the U-shaped frame 7 and the rectangular frame 3 can be effectively guaranteed. At the same time, the support surface formed between the two can be quickly adjusted. And in order to prevent the U-shaped frame 7 from sliding out from the top of the rectangular frame 3, a limiting plate is fixedly connected to the bottom of the end of the first cross plate 8, further improving the stability of the device. After the adjustment is completed, two support pads 6 are arranged on the top of the rectangular frame 3. At this time, the two support pads 6 are horizontally laid on the top of the U-shaped frame 7 and the rectangular frame 3 to form a bed for the device.

[0025] As Figure 3 , 4 shows, when the U-shaped frame 7 needs to be stored, the two support pads 6 are stacked. Strip-shaped through grooves 17 are arranged at the top of the side of the rectangular frame 3 close to each other. A plurality of second openings 16 for accommodating the upright columns 9 are arranged through the bottom surface on one side of the strip-shaped through grooves 17. And the U-shaped frame 7 is pushed. The first cross plate 8 moves between the adjacent second cross plates 19. The side of the U-shaped frame 7 can be located within the strip-shaped through grooves 17. At this time, the upper end of the upright column 9 is fitted and connected within the second opening 16, making the side wall of the U-shaped frame 7 and the side wall of the rectangular frame 3 in the same plane, improving the practicability of the device. And in order to further facilitate the user to push the U-shaped frame 7, a universal wheel 10 is fixedly connected to the bottom of the upright column 9 during use, saving the manpower of the user to push the U-shaped frame 7. And in order to improve the stability of the device after adjustment, the universal wheel 10 is a braking universal wheel, which can fix the position of the upright column 9. At this time, the device can be used for the user to sit on, and the second drawer 12 and the first drawer 5 are provided, which not only improve the space utilization rate, but also facilitate the user to take the stored items. The structure is simple and the practicability is strong.
