Description

Technical Field

[0001] The utility model relates to the technical field of lifting for recreational vehicles, and in particular to a lifting bed device for recreational vehicles. Background Art

[0002] As a means of transportation that integrates the two functions of "house" and "car", the interior space of RVs is often relatively limited. In a limited space, how to maximize the use of every inch of land while ensuring the comfort and convenience of living is an important issue that needs to be considered in RV design. In order to raise it when not in use, the bed is stored in the ceiling or closet inside the RV, thereby freeing up more space for residents to use. When the bed is needed, just lower the bed, which is convenient and quick. In addition, with the continuous development of technology, the lifting bed device for RVs is also constantly improving and optimizing. For example, some advanced lifting bed devices use self-locking technology, which can achieve self-locking during the lifting process of the bed, avoiding the sudden drop of the bed when it is not affected by external forces. At the same time, some lifting bed devices are also equipped with a mattress storage function, which can store the mattress together with the bed, further saving space. In short, the emergence of lifting bed devices for RVs not only solves the problem of limited internal space in RVs, but also provides residents with a more comfortable and convenient living environment. With the continuous advancement of technology and people's constant pursuit of quality of life, the application prospects of RV lifting bed devices will become increasingly broad.

The limit rod 3 limits the movement range of the lifting bed assembly during the lifting process to ensure the safety and stability of the lifting. The first fixed side plate 4 and the second fixed side plate 5 provide support on both sides for the lifting bed assembly so that it can be lifted and lowered smoothly. The lifting bed assembly base 6 serves as the bottom support structure of the lifting bed assembly to ensure the stability and durability of the entire assembly. The lifting platform 7 is used to carry the mattress and the user, and the height adjustment of the bed surface is achieved by lifting. The scissor fork group realizes the smooth lifting and lowering of the lifting platform 7 through its special structure under the drive of the driving component. The design of the scissor fork group makes the lifting process more stable and reduces the shaking caused by lifting.

[0015] like Figure 2 As shown, on the basis of the above method, the scissor fork member 8 further includes at least two scissor forks 9, which are composed of two cross-hinged fork rods, and the ends of the two fork rods are respectively hinged with the ends of the fork rods of the adjacent scissor forks to form end hinge points. In specific implementation, due to the hinged design between the fork rods, the scissor fork member 8 can be flexibly extended and contracted, thereby realizing the smooth lifting of the lifting platform 7. This design enables the lifting bed to adapt to different height requirements, and the lifting process is smoother. Through the cross-hinged method, the scissor fork member 8 can achieve structural compactness while ensuring strength and stability. This helps to reduce the overall volume and weight of the lifting bed device, and is easy to install and transport.

[0016] like Figure 2 As shown, on the basis of the above method, the driving component includes a support 10, a telescopic rod 11 and a driving cylinder 12.

The guide block 16 is slidably arranged on the guide rail 15, and the rotating screw 17 is rotatably connected to the side of the guide rail 15 and is connected to the guide block 16 through a thread. The hand crank 14 is connected to the side of the guide block 16, and one side of the guide block 16 is detachably connected to the lifting platform 7. In a specific implementation, the hand crank 14 provides a manual operation mode, so that when there is no electric drive, the lifting platform 7 can be lifted. The lifting platform can also be lowered even when the lifting platform is moving. The guide rail 15 provides a sliding path for the guide block 16 to ensure that it can move smoothly. The guide block 16 is detachably connected to the lifting platform 7. The guide block 16 is moved on the guide rail 15 by rotating the screw rod 17, thereby controlling the descent of the lifting platform. The screw rod 17 is connected to the guide block 16 through a thread, and can drive the guide block 16 to move on the guide rail 15 when rotating. The locking hand-cranked descent assembly provides a manual control method, allowing the user to directly operate the descent of the lifting platform through the hand crank 14.

When the driving component is working, the scissors fork member 8 realizes the smooth lifting of the lifting platform 7 through its cross-hinged structure. This design makes the lifting process more stable and reduces the shaking caused by lifting; in the absence of electric drive, the lifting platform can be manually lowered by locking the hand-cranked lowering assembly. The hand crank 14 is connected to the rotating screw 17. When the hand crank 14 is turned, the rotating screw 17 will rotate. The rotating screw 17 is connected to the guide block 16 through a thread, so that the guide block 16 slides on the guide track 15. The guide block 16 is detachably connected to the lifting platform 7, so when the guide block 16 moves, it will drive the lifting platform 7 to descend. This method is particularly suitable for mobile spaces such as RVs, which increases the convenience of use, and the manual control method also ensures the safety of the use process. Through the above steps, the new RV lifting bed device can achieve the smooth lifting and lowering of the bed surface, meeting the user's use needs in different scenarios.
