[0028] The flip mechanism 2 includes a flip plate 21, an arc-shaped side bar 22, a folding bar 23, a cross bar 24, two guide bars 25 fixed at both ends of the cross bar 24, and two gear folding devices 26. The flip plate 21 is slidably connected with the two guide bars 25. Specifically, the guide bar 25 has a long through hole. The flip plate 21 is slidably connected with the guide bar 25 through a slider arranged in the through hole. The flip plate 21 can slide above the cross bar 24 and the two guide bars 25. The arc-shaped side bar 22 is The end is connected to the guide bar 25 through a gear folding device 26, the lower end of the arc-shaped side bar 22 is hinged to the outer side of the lower end of the first supporting leg 11, one end of the folding bar 23 is hinged to the middle part of the arc-shaped side bar 22 through a connecting piece 27, and the connecting piece 27 can be, for example, a bolt, and the other end of the folding bar 23 is hinged to the inner side of the first supporting leg 11. The upper part of the first supporting leg 11 is provided with a limiting groove 111 that can be engaged with the connecting piece 27, and the limiting groove 111 is located on the side of the first supporting leg 11 close to the head of the bed.

[0029] The flip mechanism 2 of the embodiment of the present invention can be rotated to form a footboard mode or a bedside table mode. In the footboard mode, the arc-shaped side strip 22 overlaps with the first support leg 11 and is fixed by the connecting member 27, and the flip plate 21 is in contact with the tail of the bed body 1; in the footboard mode, the arc-shaped side strip 22 is separated from the first support leg 11 and is fixed by the folding strip 23. The flip mechanism 2 of the embodiment of the present invention has a reasonable structure and powerful functions, and can convert the flip plate 21 into a footboard and a bedside table, reducing the use of other additional furniture, so the utilization rate is high and the cost is reduced.

[0030] It should be pointed out that the flip mechanism 2 includes the flip plate 21, the arc-shaped side strip 22 and the folding strip 23 to realize the function of switching between the footboard mode and the bed table mode. However, the application of the cross bar 24, the guide bar 25 and the gear folder 26 allows the flip plate 21 to slide while ensuring that the distance between the flip plate 21 and the ground is appropriate, thereby changing the distance between the flip plate 21 and the head of the bed, so that the user can use it in a comfortable lying state. In some applications, the cross bar 24, the guide bar 25 and the gear folder 26 can be omitted.

[0031] Example 2

[0032] refer to Figure 4 and Figure 5The embodiment of the present invention provides a sofa bed. The difference between the sofa bed and the embodiment 1 is that, based on the embodiment 1, a limiting bolt 112 matching the arc-shaped side strip 22 is fixed to the lower part of the first supporting leg 11, and the limiting bolt 112 is located on the side of the first supporting leg 11 away from the head of the bed. In the end board mode, the arc-shaped side strip 22 overlaps with the first supporting leg 11 and is fixed by the connecting member 27 and the limiting bolt 112, and the flip plate 21 fits the tail of the bed body 1; in the end board mode, the arc-shaped side strip 22 is separated from the first supporting leg 11 and is fixed by the folding strip 23 and the limiting bolt 112. The limiting bolt 112 is cleverly designed, and the limiting bolt 112 can cooperate with the connecting member 27 and the folding strip 23 respectively, to ensure the stability of the flip mechanism 2 in the end board mode or the bed table mode.

[0033] Example 3

[0034] refer to Figure 6-Figure 9 The embodiment of the present invention provides a sofa bed. The difference between the sofa bed and the embodiment 2 is that, based on the embodiment 2, the bed body 1 includes a first sub-bed body 13, a third sub-bed body 15 and a second sub-bed body 14 located between the first sub-bed body 13 and the third sub-bed body 15. The first sub-bed body 13 includes a storage cabinet 131 and a first soft bag 132 installed on the storage cabinet 131.

The third sub-bed body 15 includes a bottom plate 151 and a third soft bag 152 fixed on the bottom plate 151. The first supporting leg 11 and the second supporting leg 12 are arranged under the bottom plate 151. The tea table body 141 is detachably connected with the storage cabinet 131 and the bottom plate 151 respectively through two bed buckles 3. The first soft bag 132, the second soft bag 142 and the third soft bag 152 form a rectangular mattress as a whole.

[0035] Among them, Figure 1As a reference orientation, the upper surface soft covering cloth of the second soft bag 142 is an integral structure with the upper surface soft covering cloth of the third soft bag 152. The upper surface soft covering cloth of the third soft bag 152 includes a fixed area and a movable area. The movable area is connected to the upper surface soft covering cloth of the second sub-soft bag 142. The upper surface soft covering cloth of the second sub-soft bag 142 is fixed on the upper surface soft covering cloth of the second sub-soft bag 142. The area of ​​the fixed area is the same as that of the upper surface soft covering cloth of the second sub-soft bag 142. An open groove is configured at the lower part of the second soft bag 142 on the side close to the third soft bag 152. The first sub-soft bag 143 and the second sub-soft bag 144 are arranged in the open groove. The lower surface soft covering cloth of the first sub-soft bag 143 is an integral structure with the lower surface soft covering cloth of the second soft bag 142. The upper surface soft covering cloth of the first sub-soft bag 143 is an integral structure with the upper surface soft covering cloth of the second sub-soft bag 144. The first sub-soft bag 143 and the second sub-soft bag 144 can be stacked together with the second sub-soft bag 142 on the third soft bag 152 to form a sofa structure.

[0036] The sofa bed of the embodiment of the present invention can be converted between the bed and sofa forms. Specifically, the bed body 1 with the flip mechanism 2 can be split into a sofa with a storage cabinet 131, a sofa with a storage board and a coffee table body 141, so that one piece of furniture has multiple uses, and can be used for bedroom and living room space conversion, study, meeting guests, etc.

[0037] Example 4

[0038] refer to Fig. 9 and Fig.10 An embodiment of the present invention provides a sofa bed. The difference between the sofa bed and the embodiment 3 is that, on the basis of the embodiment 3, two speaker bedside tables 4 are fixed on both sides of the first sub-bed body 13. The speaker bedside tables 4 are installed with decorative lights 41 and Bluetooth speakers 42. An installation space is constructed under the Bluetooth speaker 42, and a pull-out mechanism 43 is arranged in the installation space.

[0039] The pull-out mechanism 43 includes a drawer 431 and an "L"-shaped flip plate, wherein the "L"-shaped flip plate includes a cover plate 432 and a support plate 433 connected vertically, wherein one end of the cover plate 432 is connected to the end of the drawer 431, and the cover plate 432 is the same length as the drawer 431, and one end of the support plate 433 is rotatably connected to the front end of the drawer 431 through a hydraulic rod 434, and the length of the support plate 433 is the same as the height of the drawer 431. The pull-out mechanism 43 can be hidden in the installation space and does not occupy space, or it can be pulled out, and the installation space is used to store items, and the support plate 433 is used to form a storage board at the head of the bed, which is convenient to use.
