[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 6 The utility model provides a technical solution: a foldable upper bunk bed specially used for RVs, including a bed board. The bed board here is required to be relatively light in weight and strong in strength. The bed board includes a support frame 1. A plurality of support rods 11 vertically and cross-connected to each other are arranged inside the support frame 1. The ends of the support rods 11 are respectively connected to the inner walls of the support frame 1. The support rods 11 form a mesh structure, which mainly plays a supporting role. The support frame 1 is sealed by a support plate 2, and the support plate 2 is connected to the support rods 11. In actual use, the support rods 11 can be a hollow structure, and the support frame 1 can be formed by welding four hollow pipe fittings. The bed board designed in this way is not only strong, but also can reduce weight.

[0028] like Figure 1 and Figure 2 As shown, at least two symmetrically arranged support rails 7 and a drive screw 8 are provided on one side of the bed board, the support rails 7 and the drive screw 8 are parallel and both vertically downward, and the support rails 7 are distributed on both sides of the drive screw 8. In actual use, the number of the support rails 7 is two;

[0029] The support rail 7 is provided with a matching slider, and the drive screw is provided with a matching nut, so the side of the bed board is rotatably connected to the slider 19 on the support rail 7 and the nut 14 on the drive screw 8. The specific connection structure is as follows: Figure 3 and Figure 4As shown, on the bottom of the bed board near one side of the support guide rail 7, there are respectively a plurality of rotating blocks 20 corresponding to the lead nut 14 and the slider 19. The rotating blocks 20 are respectively rotatably installed in the U-shaped supports 12, and one end of each U-shaped support 12 extends outside the side of the bed board and is respectively connected to the lead nut 14 and the slider 19, as Figure 1 shown, the rotating block 20 is specifically installed at the edge of the support frame 1;

[0030] At both ends of the bed board and at the end far from the support guide rail 7, there are respectively rotatably connected with drawstrings 3. The drawstrings 3 are inclined towards the support guide rail 7. Here, the drawstrings 3 are rigid rods or ropes. The rope is preferably a steel wire rope. The bottom of the drawstring 3 is connected to the annular seat 21. Inside the annular seat 21, there is a support shaft 10 rotatably installed. The support shaft 10 is vertically arranged on the side of the bed board, as Figure 3 shown, the support shaft 10 is installed on the side of the support frame 1, so that the bottom of the drawstring 3 can freely rotate around the support shaft 10; the top of the drawstring 3 is connected to the rotating seat 17. The rotating seat 17 is rotatably arranged in the U-shaped seat body 18, so that the top of the drawstring 3 can also freely rotate. The other end of the U-shaped seat body 18 is connected to the connecting disc 9. The connecting disc 9 is installed on the vehicle body 4. The connecting disc 9 and the vehicle body are fastened by bolts.

[0031] Specifically, when this application is in use, a driving mechanism is connected to one end of the transmission lead screw 8, as Figure 3 shown, the driving mechanism drives the transmission lead screw 8 to rotate. The transmission lead screw 8 drives the bed board to be in a horizontal position, and at this time the bed board is opened; as Figure 4 shown, the transmission lead screw 8 drives the side of the bed board to lift upwards so that it is placed parallel to the vehicle body 4, and at this time the bed board is closed;

[0032] And as the most important drawstring 3 for maintaining the rotation of the bed board, its two ends are respectively rotatably connected to the vehicle body 4 and the side of the bed board. Therefore, during the folding or flattening movement of the bed board, the drawstring 3 is always in a taut state.

[0033] The above-mentioned driving mechanism and support guide rail 7 are both installed on the vehicle body 4. The other end of the transmission lead screw 8 is rotatably connected to the vehicle body 4. There are respectively a plurality of installation grooves 6 on the vehicle body 4. The support guide rail 7 and the transmission lead screw 8 are respectively arranged in the installation grooves 6. Among them, the driving mechanism includes a reduction box 16 connected to one end of the transmission lead screw 8. The other end of the reduction box 16 is connected to the driving motor 15. During the actual operation process, a switch for controlling the forward and reverse rotation of the driving motor is installed on the vehicle body around the bed board, which is convenient for controlling the driving motor to drive the transmission lead screw to rotate.

[0034] It should be noted that, as Figure 3As shown, when the bed board is horizontal, the U-shaped support 12 is located at the bottom of the support frame 1, and the U-shaped support 12 and the slider 19 are located at the bottom of the support guide rail 7. When the bed board is folded on the side of the vehicle body 4, the U-shaped support 12 is just located at the top of the support guide rail 7.

[0035] A limit seat 13 that contacts the U-shaped support 12 and the slider 19 is provided below the support guide rail 7. The limit seat 13 is L-shaped and is arranged on the vehicle body 4, and can be specifically arranged in the installation groove 6. It should be emphasized again that when the bed board is horizontal, the U-shaped support 12 supports at the bottom of the support frame 1, and the bottom of the U-shaped support 12 sits on the top of the limit seat 13. Therefore, the edge of the bed board can be stably supported. With the cooperation of the zipper 3, the bed board has a large bearing capacity and is very stable.

[0036] Based on the above embodiments, it can be further optimized. During actual use, the installation groove provided on the vehicle body 4 will inevitably be exposed, which affects the aesthetics. As Figure 6 shown, a shielding curtain 5 can be hung above the installation groove of the vehicle body. After the square bed board is placed horizontally, the shielding curtain 5 can be pulled down to cover the installation groove.
