[0031] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly specifying the number of the technical features referred to. Thus, a feature designated "first" or "second" may explicitly or implicitly include one or more of the features. Furthermore, the terms "first," "second," and the like are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate, such that the embodiments of the present invention described herein can be implemented in an order other than that illustrated or described herein.

[0033] Please refer to Figure 1-8 As shown, a folding bed includes a bed frame 1 and a bed board installed on the bed frame 1. Bed legs 11 that can be rotated and folded are provided at both ends of the bed frame 1. A supporting hinge 12 is provided in the middle of the bed frame 1. Two symmetrical bed supports 13 are hinged at both ends of the supporting hinge 12, that is, the two symmetrical bed supports 13 are folded in half with a gap by being hinged at both ends of the supporting hinge 12. Correspondingly, the bed board member 2 includes two symmetrically arranged bed support boards, which are formed as a whole by blow molding or injection molding, and then respectively mounted on the outer frame of the bed frame 13, and can be folded together with the bed frame 13 along the hinge point. The bed support board near the end of the support hinge piece 12 forms a convex portion 213 by protruding from the bed frame 13, and the length of the convex portion 213 protruding from the bed frame 13 is set to half the length of the support hinge piece 12. In this way, when the folding bed is unfolded, the two symmetrical convex portions abut so that the upper surfaces of the bed support boards 21 can be aligned to form a comfortable lying surface. At the same time, when the folding bed is folded, the two convex portions are spaced a certain distance apart to form a storage space. After the two symmetrically arranged bed support boards 21 are folded along the two ends of the support hinge piece 12, the folded thickness of the bed body is close to the diameter of a curled mattress 3. This design is conducive to the reasonable and orderly storage of the bed body and the mattress 3. Specifically, it can be as follows Figure 6and 7 The bed support plate 21 is formed by blow molding or injection molding to increase the comfort of the folding bed's lying surface and provide better support. It can also be designed to mimic the curves of the human body and fit the lying surface to increase comfort, thereby reducing the overall thickness of the mattress.

[0034] Based on the above technical solution, the two symmetrically arranged bed support plates 21 are folded along the ends of the support hinge 12 to form a receiving groove 214 between the two protrusions 213. The receiving groove 214 can be used to accommodate the rolled-up mattress 3, which not only makes the mattress and the folding bed neatly stored but also reduces the overall volume, thus saving storage space. In addition, the middle portion of the bed frame 1 is optionally provided with a support foot 14 to enhance the stability of the bed when unfolded. The upper end of the support foot 14 is matingly connected to the middle portion of the support hinge 12. When the bed is folded, the support foot 14 can be positioned in the middle of the entire folded body.

[0035] It can be understood that, preferably, the thickness of the mattress 3 can be selected to be 5-10 cm. Therefore, the present application can also include a mattress 3 that can be rolled up. After the mattress 3 is rolled up, it can be placed in the aforementioned receiving groove 214 for storage. The volume of the mattress 3 itself can be smaller after being rolled up.

[0036] In a preferred embodiment, there are two groups of support hinge plates 12, which are correspondingly arranged at the hinges of the two side frames of the two symmetrically arranged bed supports 13. It can be clearly seen in the drawings and can be implemented with the existing technology, so it will not be described here.

[0037] Specifically, the support hinge 12 is configured in an "L" shape and includes a support portion 121 that supports the position-limiting bed support 13. As will be appreciated, the support portion 121 provides support for the bed support 13 after it is deployed, allowing the two symmetrical bed supports 13 to be laid flat with the support portion 121 as the support surface, making the deployed structure more stable. In use, the user unfolds the folding bed frame of this application, lays out the symmetrical bed supports 13, and then rotates the two symmetrical bed supports 13 until they are parallel to the support hinge 12 and horizontally overlap with the support portion 121.

[0038] Of course, optionally, the bed support 13 further includes an inner bed support 131 and an outer bed support 132 that are hinged to each other. One end of the inner bed support 131 is hinged to the support hinge plate 12. The bed support plate 2 correspondingly includes an inner bed support plate 211 and an outer bed support plate 212. The inner bed support plate 211 is sleeved onto the inner bed support 131, and the outer bed support plate 212 is sleeved onto the outer bed support 132. The inner bed support plate 211 is longer than the outer bed support plate 212 along the length of the bed body, so that when the outer bed support plate 212 is rotated and folded about the hinge point with the inner bed support plate 211, the end of the outer bed support plate 212 not connected to the inner bed support plate 211 abuts the lower end of the support hinge plate 12. This design enables the folding bed to achieve better space saving, that is, reduce the volume after folding.

[0039] In order to facilitate folding and storage, a notch 215 is provided on the protrusion 213. The cross-section of the notch 215 is arranged in a fan shape. The notch 215 is provided at the extending end of the bed support plate toward the middle and opens downward. The notches 215 of the two symmetrical bed support plates are mirror images of each other to form a semicircular slot. It can be understood that the notch 215 is toward the axis of the mattress 3 winding column. In this way, after the bed support plate 21 is folded, the semicircular slot can fit and accommodate the mattress 3 after the limited winding, and the mattress 3 can be semi-clamped and stored in the inner side of the folding bed. In this way, after folding, it can be more beautiful and simple, and the overall volume is smaller.

[0040] On this basis, it also includes a connecting rod 15, and both ends of the connecting rod 15 are respectively connected to the middle of the support hinge piece 12. In addition, the support foot 14 is arranged below the connecting rod 15. The optional support foot 14 can be hinged to the middle of the bed plate 2 through the connecting rod 15 and can be rotated and folded.

[0041] Of course, the outer periphery of the bed plate 2 is preferably provided with a circumferential boss 22, which is fixedly engaged with the bed frame 1, which not only protects the bed frame 1 and improves the stress strength of the bed plate, but also provides a space for hiding the bed foot 11. During use, when the folding bed frame of the present application is in the folded state, the bed support 13 is folded toward the middle, and finally presents an "I" shape. Figure 2-4 In this case, the support legs 14 and the rotatable bed leg members 11 on both sides are hidden between the bed frame 1 or the bed board 2, which can better store the bed and save space. Furthermore, if the bed is a four-fold bed, one end of the bed leg member 11 is hinged to the outer bed frame 13, and the other end does not extend beyond the hinge point between the inner and outer bed frames 13, making it easier to hide the bed leg member 11 in the bed board or bed frame, saving space.

[0042] In an optional embodiment, a handle groove 23 is provided at the outermost end of the bed support plate 21 to facilitate the folding and carrying operations of the folding bed.

[0043] The folding bed provided by the present application has at least the following beneficial effects:

[0044] 1. The present application forms a one-piece bed board by injection molding or blow molding and then sets it on the bed frame to provide comfortable support and reduce the thickness of the mattress, making the bed board and mattress lightweight. It is easy to operate and the overall appearance is simple and beautiful. At the same time, the folded thickness of the bed body is close to the diameter of a curled mattress, which makes it easy to store the bed body and mattress in an orderly manner.

[0045] 2. This application reduces the storage volume of the mattress, bed legs and bed frame through the design of circumferential bosses, accommodating grooves, etc., uses a lighter and thinner mattress with the function of accommodating the rolled-up mattress in the accommodating groove, and reduces the storage space when the mattress is stored together with the folding bed. In addition, the combination of handle grooves can achieve the effect of taking into account aesthetics, portability and practicality, saving space while better improving the user experience.

[0046] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present application. These improvements and replacements should also be regarded as the scope of protection of the present application.
