[0030] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] like Figure 1-9As shown, the folding bed in this embodiment includes a bed frame with an unfolded state and a folded state, a locking device 8 for locking the bed frame in the unfolded state, the bed frame includes a fence assembly 1, a plurality of vertical rods 2 extending in the up and down directions for supporting the fence assembly 1, and a first connecting member 3 fixedly arranged at the upper end of each vertical rod 2, and the downward extending parts of the plurality of vertical rods 2 from the first connecting member 3 are no longer connected to each other by other rods. In this embodiment, the fence assembly 1 is rectangular and includes four adjacent foldable side portions 4. Of course, the fence assembly 1 can also be other polygons such as triangles, pentagons, hexagons, etc. Each vertical rod 2 is arranged between two adjacent foldable side portions 4, and both ends of each foldable side portion 4 are rotatably connected to the corresponding first connecting member 3.

[0033] like Figure 2 , 5 -6, the vertical rod 2 can be configured as a telescopic rod assembly, specifically including a lower vertical rod 2b for supporting the ground and an upper vertical rod 2a arranged above the lower vertical rod 2b, and the upper vertical rod 2a can be connected to the lower vertical rod 2b by relative sliding along the up and down directions. The advantage is that the telescopic height of the vertical rod 2 can be adjusted when the bed frame is in the folded state to further reduce the folding volume of the entire folding bed.

[0034] The foldable side portion 4 includes a first connecting rod 5, a second connecting rod 6, and a second connecting member 7 arranged between the first connecting rod 5 and the second connecting rod 6. The first connecting rod 5 includes a first upper rod 5a and a first lower rod 5b arranged in parallel with each other, and the first upper rod 5a is located above the first lower rod 5b. The second connecting rod 6 includes a second upper rod 6a and a second lower rod 6b arranged in parallel with each other, and the second upper rod 6a is located above the second lower rod 6b. The adjacent ends of the first upper rod 5a and the second upper rod 6a are rotatably connected by the second connecting member 7, and the two ends of the first upper rod 5a and the second upper rod 6a that are far away from each other are respectively rotatably connected to the corresponding first connecting member 3; the adjacent ends of the first lower rod 5b and the second lower rod 6b are rotatably connected by the second connecting member 7, and the two ends of the first lower rod 5b and the second lower rod 6b that are far away from each other are respectively rotatably connected to the corresponding first connecting member 3.

[0035] Specifically, Figure 2 As shown, the first upper rod 5a and the second upper rod 6a on the same foldable side portion 4 have the same length, the first lower rod 5b and the second lower rod 6b on the same foldable side portion 4 have the same length, and the length of the first upper rod 5a is less than the length of the vertical rod 2, and the length of the first lower rod 5b is less than the length of the vertical rod 2. Figure 5-6As shown, when the bed frame is in a folded state, the second connecting member 7 moves downward and drives the first connecting rod 5 and the second connecting rod 6 to retract mutually between the two vertical rods 2 adjacent to the second connecting member 7, and the height of the lower end of the second connecting member 7 from the supporting surface is greater than or equal to the height of the lower end of the two vertical rods 2 adjacent to the second connecting member 7 from the supporting surface. In this way, in the folded state, the second connecting member 7 is always located above the supporting surface or flush with it, further reducing the influence of the second connecting member 7 on increasing the folding volume of the folding bed.

[0036] Specifically, Figure 1 As shown, the first connecting member 3 includes a first connecting member body 3a and a first rod portion 3b and a second rod portion 3c fixed on the first connecting member body 3a and extending outward in a horizontal direction. The angle between the extension direction of the first rod portion 3b and the extension direction of the second rod portion 3c is 90 degrees. The extension direction of the first rod portion 3b is consistent with the extension direction of the first connecting rod 5 whose end is rotatably connected thereto, and the extension direction of the second rod portion 3c is consistent with the extension direction of the second connecting rod 6 whose end is rotatably connected thereto.

[0037] like Figure 3 , 7 -9, the locking device 8 includes a locking block 8a movably arranged on the second connecting member 7, and a limit block 8c, the limit blocks 8c are respectively arranged above the rotation connection between the first upper rod 5a and the first connecting member 3, and above the rotation connection between the second upper rod 6a and the first connecting member 3, or / and are respectively arranged above the rotation connection between the first lower rod 5b and the first connecting member 3, and above the rotation connection between the second lower rod 6b and the first connecting member 3. When the bed frame is folded, the setting of the limit block 8c limits the folding mode of the second connecting member 7 moving upward. The lower part of the locking block 8a is rotatably arranged on the second connecting member 7 around the rotating shaft 8b. The locking device 8 has a locked state and an unlocked state. Figure 8 As shown, when the locking device 8 is in the locked state, the upper end of the locking block 8a abuts against two adjacent ends of the first upper rod 5a and the second upper rod 6a respectively; Fig. 9 As shown, when the locking device 8 is in the unlocked state, the locking block 8a rotates around the rotating shaft 8b to disengage the upper end of the locking block 8a from the lower ends of the two adjacent ends of the first upper rod 5a and the second upper rod 6a, and the second connecting member 7 can move downward to drive the bed frame to fold.

[0038] Example 2

[0039] like Fig.10As shown, the difference between this embodiment and embodiment 1 is that the fence assembly 1 in this embodiment includes four side portions, and the side portions include two foldable side portions 4 with opposite sides parallel to each other and two fixed side portions 9 with opposite sides parallel to each other, wherein the structure of the foldable side portion 4 is consistent with that in embodiment 1, and the fixed side portion 9 cannot be further folded during the folding process of the folding bed.
