DETAILED DESCRIPTION

[0028] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0030] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0031] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0032] like Figure 1-10 As shown, in one embodiment provided in the present application, the folding structure specifically includes two supporting cross bars 100 and five folding units 200 .

[0033] like Figure 1 As shown, the two support crossbars 100 are arranged side by side in a first direction, and the five folding units 200 are connected between the two support crossbars 100. The two ends of each folding unit 200 are respectively connected to the two support crossbars 100, and the five folding units 200 are arranged side by side in a second direction, wherein the first direction is perpendicular to the second direction, the first direction is the width direction of the folding structure in the left and right directions, and the second direction is the length direction of the folding structure. Each folding unit 200 can be folded or unfolded in the first direction, so that the two support crossbars 100 are folded close to each other or unfolded away from each other.

[0034] like Figure 2-3 As shown, the folding unit 200 includes two folding components 210, a first folding seat 220 is connected between the two folding components 210, and the two folding components 210 are rotatably connected to the two ends of the first folding seat 220, so that the two folding components 210 can be rotated in the first direction relative to the first folding seat 220 to be folded or unfolded. The folding component 210 further includes a first rotating rod 211, a second rotating rod 212 and a second folding seat 213. The length of the first rotating rod 211 is not greater than the length of the second rotating rod 212. The two ends of the first rotating rod 211 are rotatably connected to the first folding seat 220 and the second folding seat 213, respectively. One end of the second rotating rod 212 is rotatably connected to the second folding seat 213, and the other end of the second rotating rod 212 is connected to the supporting cross bar 100. The first rotating rod 211 and the second rotating rod 212 can be rotated in the first direction relative to the first folding seat 220 and the second folding seat 213 to be folded or unfolded. When the folding unit 200 is unfolded, as shown in FIG. Figure 2 As shown, the first rotating rod 211, the second rotating rod 212 and the second folding seat 213 in the two folding components 210 are in a trapezoidal structure, the two supporting cross bars 100 are spread apart from each other, the two first rotating rods 211 are connected end to end through the first folding seat 220, and the first rotating rod 211 and the second rotating rod 212 play a supporting role for the supporting cross bar 100; when the folding unit 200 is folded, as shown in FIG. Figure 3 As shown, the first rotating rod 211 and the second rotating rod 212 are rotated and folded in the first direction, the first rotating rod 211, the second rotating rod 212 and the second folding seat 213 in the two folding components 210 are in an M-shaped structure, and the two supporting cross bars 100 are folded close to each other.

[0035] That is, the user can fold the folding structure in the first direction by folding the folding unit 200, thereby reducing the size of the folding structure in the first direction after being folded, making it convenient for the user to store and carry the folded folding structure.

[0036] Furthermore, if Figure 4-5 As shown, the first folding seat 220 includes a first connecting portion 221 and a second connecting portion 222, the first connecting portion 221 is hinged to the second connecting portion 222, the first connecting portion 221 is connected to the first rotating rod 211 in the folding component 210, and the second connecting portion 222 is connected to the first rotating rod 211 in another adjacent folding component 210. At the same time, one end of the first connecting portion 221 extends toward one side of the second connecting portion 222 to form a limiting portion 223, and the limiting portion 223 is suitable for limiting the maximum unfolding angle of the second connecting portion 222 and the first rotating rod 211. In the embodiment shown, the maximum unfolding angle of the second connecting portion 222 and the first rotating rod 211 is limited to 180°.

[0037] A locking member 230 is also provided on the first rotating rod 211 connected to the second connecting portion 222, and a limiting groove 224 cooperating with the locking member 230 is provided on the limiting portion 223. The locking member 230 is suitable for being detachably embedded in the limiting groove 224, so as to keep the two first rotating rods 211 in the unfolded state when the external force does not exceed the preset value. The specific structure of the locking member 230 can be implemented as an elastic locking piece 231, on which a limiting protrusion 232 is provided. The elastic locking piece 231 is arranged in the first rotating rod 211, and the limiting protrusion 232 can pass through the opening on the first rotating rod 211 and protrude from the surface of the first rotating rod 211. When the two first rotating rods 211 are maintained in the unfolded state, the limiting protrusion 232 on the elastic locking piece 231 is embedded in the limiting groove 224 to limit the rotation of the two first rotating rods 211. When the user wants to fold the folding unit 200, the user can press the unlocking button 225 on the limiting portion 223, and the unlocking button 225 is connected to the limiting groove 224, so that the unlocking button 225 can be pressed to push the limiting protrusion 232 to the outside of the limiting groove 224, thereby unlocking the first rotating rod 211.

[0038] In some preferred embodiments, the support cross bar 100 is also configured to be foldable, and the support cross bar 100 can be turned over and folded in the second direction, so that the volume of the folded structure is further reduced. Figure 1 and Figure 6-10As shown, the supporting cross bar 100 includes two supporting rod segments 110, and two adjacent supporting rod segments 110 are connected by a first connecting seat 120. The two supporting rod segments 110 are rotatably connected to the two ends of the first connecting seat 120 respectively. The supporting rod segment 110 includes a first support rod 111 and a second support rod 112. The length of the first support rod 111 is less than the length of the second support rod 112. The first support rod 111 and the second support rod 112 are connected by a second connecting seat 113. The first support rod 111 and the second support rod 112 are rotatably connected to the two ends of the second connecting seat 113 respectively. The first support rod 111 is also provided with a third connecting seat 114. In other words, one end of the first support rod 111 is rotatably connected to the second connecting seat 113, and the other end of the first support rod 111 is provided with the third connecting seat 114. The two ends of the second support rod 112 are rotatably connected to the first connecting seat 120 and the second connecting seat 113 respectively. When the support cross bar 100 is unfolded for use, the first support rod 111 and the second support rod 112 in the support rod segment 110 are connected end to end via the second connecting seat 113, and the two second support rods 112 of two adjacent support rod segments 110 are connected end to end via the first connecting seat 120; when the user wants to fold the support cross bar 100, the user can fold the first support rod 111 and the second support rod 112 in the two support rod segments 110 inward in the second direction in sequence, as shown in the steps below. Figure 6-10 As shown, finally, the first connecting seat 120 and the second connecting seat 113 are arranged in parallel, the first support rod 111 and the second support rod 112 are arranged side by side between the first connecting seat 120 and the second connecting seat 113, and the first support rod 111 and the second support rod 112 are both arranged perpendicular to the first connecting seat 120 and the second connecting seat 113.

[0039] Preferably, the distance d between the hinge points of the two second support rods 112 on the first connecting seat 120 is greater than the distance s between the hinge points of the first support rod 111 and the second support rod 112 on the second connecting seat 113. Preferably, the distance d between the hinge points of the two second support rods 112 on the first connecting seat 120 is greater than twice the distance s between the hinge points of the first support rod 111 and the second support rod 112 on the second connecting seat 113, that is, d>2s. Therefore, when the first support rod 111 and the second support rod 112 are folded to be perpendicular to the first connecting seat 120 and the second connecting seat 113, there is enough space between the two second support rods 112 to accommodate the first support rod 111, so that the folded support cross bar 100 can be rectangular, which is convenient for users to store and carry.

[0040] Further, for the foldable support crossbar 100, each folding unit 200 is connected to the support crossbar 100 by connecting to each connection seat on the support crossbar 100, and the two second rotating rods 212 in each folding unit 200 are respectively connected to one of the first connection seat 120, the second connection seat 113, and the third connection seat 114 on the two support crossbars 100 and are arranged between the two support crossbars 100. In addition, the folding unit 200 is connected to the first connection seat 120 and the second connection seat 113 to form a fixed folding unit 200b, and the folding unit 200 is connected to the third connection seat 114 to form a movable folding unit 200a. The second rotating rods 212 at both ends of the fixed folding unit 200b are fixedly connected to the first connecting seat 120 or the second connecting seat 113, the fixed folding unit 200b is vertically arranged with the first connecting seat 120 or the second connecting seat 113, and the fixed folding unit 200b cannot be turned over in the second direction relative to the first connecting seat 120 or the second connecting seat 113; the second rotating rods 212 at both ends of the movable folding unit 200a are rotatably connected to the third connecting seat 114, and the movable folding unit 200a can be turned over in the second direction relative to the third connecting seat 114, such as Figure 6 As shown, the movable folding unit 200a can be turned over to be consistent with the fixed folding unit 200b and vertically arranged between the two supporting cross bars 100, as shown in FIG. Figure 7-10 As shown, the movable folding unit 200a can also be turned over to be arranged side by side with the first support rod 111. At this time, the user can fold the first support rod 111 and the movable folding unit 200a inwardly in the second direction to fold the supporting cross bar 100. It is worth noting that the movable folding unit 200a can only be rotated, folded or unfolded relative to the third connecting seat 114 in the second direction, and cannot be rotated, folded or unfolded relative to the third connecting seat 114 in the first direction.

[0041] The present application also provides a folding bed, which includes the above-mentioned folding structure and a bed cloth, wherein the bed cloth is connected between two supporting cross bars 100. When the user unfolds and uses the folding bed, the bed cloth is stretched out by the folding structure, and the user can lie on the bed cloth to rest. When the user folds and folds the folding bed, the folding bed can be folded and folded in a first direction and a second direction at the same time, so that the folded folding bed is in the shape of a rectangular parallelepiped, thereby reducing the volume of the folding bed and making it convenient for the user to carry and store it.

[0042] Specifically, when the folding bed is unfolded for use, the supporting crossbar 100 and the folding unit 200 are in an unfolded state. Figure 1As shown, the first support rod 111 and the second support rod 112 are connected end to end through the first connecting seat 120 and the second connecting seat 113, and the two first rotating rods 211 in the folding unit 200 are connected end to end through the first folding seat 220, and the locking member 230 cooperates with the limiting groove 224 to keep the two first rotating rods 211 in the unfolded state. The entire folding unit 200 has a trapezoidal structure to support the supporting cross bar 100, so as to spread out the bed cloth for the user to lie down and rest. When the user folds and folds the folding bed, the user first presses the unlocking button 225 to release the limiting of the first rotating rod 211 by the locking member 230, and then rotates and folds the first rotating rod 211 and the second rotating rod 212 in the first direction, so that the folding unit 200 has an M-shaped structure as a whole, and the two supporting cross bars 100 are folded close together, and the folding bed is folded in the first direction. Figure 6 Then, the user can flip the movable folding unit 200 connected to the third connecting seat 114 to be arranged in parallel with the first support rod 111, and then fold the first support rod 111 and the second support rod 112 inward in the second direction in sequence, so that the first connecting seat 120 and the second connecting seat 113 are arranged in parallel, the first support rod 111 and the second support rod 112 are arranged vertically between the first connecting seat 120 and the second connecting seat 113, and each folding unit 200 is arranged between the first support rod 111 and the second support rod 112 or between two first support rods 111, and the folding bed is folded in the second direction, as shown in FIG. Figure 7-10 shown.

[0043] To sum up, the folding bed in the present embodiment can be folded in the first direction and the second direction of the bed body, and the dimensions of the folding bed in the first direction and the second direction can be reduced, so that the folded folding bed is rectangular in shape as a whole. Under the premise of ensuring the stability and reliability of the structure of the folding bed, it is convenient for users to carry, transport and store it. When in use, the user only needs to rotate the folding unit 200 to the unfolded state, and the locking member 230 will automatically lock the folding unit 200 to keep it in the unfolded state. When folding, the user only needs to press the unlocking button 225 to release the locking member 230 from limiting the folding unit 200 to fold the folding bed. The operation is simple and convenient, which can enhance the user experience.
