[0026] like Figure 1-5 As shown: A shared folding bed in this embodiment includes a planar four-bar mechanism, a foot assembly for changing the height of the bed arranged below the planar four-bar mechanism, and an inflatable mattress 1 arranged above the planar four-bar mechanism; the planar four-bar mechanism includes telescopic assemblies arranged in parallel to each other for changing the length of the bed, and connecting rods Ⅰ7 and Ⅱ8 arranged inside the two telescopic assemblies for changing the width of the bed, one end of the connecting rod Ⅰ7 and the connecting rod Ⅱ9 are respectively hinged to the telescopic assembly, and the other ends are hinged to each other; a locking mechanism for locking the connecting rod Ⅰ7 and the connecting rod Ⅱ9 is arranged at the hinge of the connecting rod Ⅰ7 and the connecting rod Ⅱ9. The telescopic assembly can adopt the specific telescopic assembly composed of an internal threaded tube 2, a screw rod 10 and a hand wheel 11 described below, and of course, other telescopic assemblies in the prior art can also be adopted.

[0027] The shared folding bed is Figure 4state, and the inflatable air mattress 1 can be folded together like a sheet in the deflated state. When in use, the screw rod is removed from the internal threaded tube by the hand wheel 11. During the extension of the screw rod, the connecting rods Ⅰ7 and Ⅱ9 are extended, and the length of the screw rod 10 is adjusted according to the individual height or the size of the actual space. After the locking block 8 described below is placed in the locking groove, the upper part of the bed body is fixed and stabilized. Then, the support legs Ⅰ3 and Ⅱ6 described below are opened, and the two ends of the rope 4 are placed on the two support legs Ⅰ3 and Ⅱ6 to complete the extension of the mechanical part. Finally, the inflatable mattress 1 is placed above the planar four-bar mechanism for inflating and can be used directly. Therefore, the present invention improves the problem that the traditional folding bed is difficult to fold due to the obstruction of the mattress, and compared with the folding bed with a sling, the shared folding bed described in the present invention does not wrap the human body excessively like a sling, and long-term use will not cause discomfort to the human body.

[0028] In this embodiment, an air supply system for inflating or abandoning the air mattress 1 is also included, and the air supply system includes an air pump (not marked in the figure), a control unit, a communication module, a QR code and an electronic switch for controlling the start and stop of the air pump; the control unit is bidirectionally connected to the communication module and unidirectionally connected to the electronic switch, and is used to receive application instructions sent from the mobile terminal and control the connection or disconnection of the electronic switch; the QR code is set on the air mattress or the foot assembly, and the mobile terminal sends the application instruction to the communication module by scanning the QR code. Further, the air pump preferably uses the model "FQY4816-24V" micro air pump of Chengdu Qihai Electromechanical Manufacturing Co., Ltd., and the air pump is limitedly set inside the air mattress 1 and located at the foot of the person. Of course, the air pump can also be other air pumps in the prior art. The control unit can be a PLC programmable controller, a single-chip microcomputer and other control units. The present invention preferably uses a single-chip microcomputer with a small size and low price. The electronic switch is preferably a small and low-cost relay, and its electrical connection relationship has been described in the text. Those skilled in the art can implement it with the existing technology, so it will not be described here for brevity.

[0029] In this embodiment, the anchor assembly includes legs I3 and II6 respectively hinged on the same telescopic assembly, and ropes 4 for changing legs I3 and II6 are respectively arranged on legs I3 and II6 at both ends. The preferred use of such anchor assembly further reduces production costs.

[0030] In this embodiment, the locking mechanism includes an upper locking groove provided on the connecting rod I7 or the connecting rod II9 and a locking block 8 matched with the locking groove. The locking block 8 can not only fill the gap left by the hinge, i.e., the locking groove, so that the inflatable mattress is flatter on the plane of the planar four-bar mechanism, and the user can sleep more comfortably; secondly, it is more conducive to the stability of the shared folding bed in the extended state and the reliability of use.

[0031] In this embodiment, the locking block is connected to the connecting rod I7 by sliding along the axis of the connecting rod I7 with a single degree of freedom, or is connected to the connecting rod II9 by sliding along the axis of the connecting rod II9 with a single degree of freedom. This arrangement allows the locking block 8 to be directly slid here when the connecting rods I7 and II9 need to be locked, thus avoiding temporary assembly of parts and loss of parts.

[0032] In this embodiment, the locking block 8 is hinged to the outer side wall of the connecting rod I7 or the connecting rod II9.

[0033] In this embodiment, the lower ends of the legs I3 and II6 are provided with rollers (marked in the figure); the rollers may be similar to the rollers of the model "Tongxing Caster 4-18" of Hengshui Hengtai Caster Co., Ltd., or the casters of the model "1.5-inch environmentally friendly PP" of Huizhou Kaipuo Plastic Products Co., Ltd. This is the prior art and will not be described here. The rollers can be provided to facilitate the movement of the shared folding bed, making it more practical and convenient.

[0034] In this embodiment, a sleeping bag 12 is detachably connected to the inflatable mattress 1 .

[0035] In this embodiment, an ice pad (marked in the figure) is arranged on the contact surface between the sleeping bag 12 and the inflatable mattress 1. The ice pad can be made of a compound composed of water and ice crystals. This is a prior art and will not be described in detail here. Since it is hot in summer, people lying on the ice pad can feel cool, which improves the comfort of the user.

[0036] In this embodiment, the bottom edge of the air mattress 1 is provided with a buckle 13 for fixed connection with the telescopic assembly, and the buckle can be glued to the bottom of the air mattress with industrial glue. The existence of the buckle 13 can make the air mattress firmly fixed on the planar four-bar mechanism, and the air mattress is not easy to fall off when the user turns sideways or moves, which provides safety for the user when using it. Secondly, this method is faster to fix the air mattress, and it can also be convenient to make adaptive adjustments when necessary.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
