[0048] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0049] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0051] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0052] This embodiment provides a foldable smart bed. Figure 1 and Figure 2 As shown, the smart bed includes a folding bed frame, a first bed frame 70 and a second bed frame 80. The folding bed frame supports and connects the bottom surfaces of the first bed frame 70 and the second bed frame 80. The first bed frame 70 and the second bed frame 80 are arranged along the length direction of the smart bed for supporting the user.

[0053] like Figure 2-Figure 9 As shown, the folding bed frame includes a first fixed frame 10 and a second fixed frame 20. The first fixed frame 10 supports the first bed body 70, and the second fixed frame 20 supports the second bed body 80. The first fixed frame 10 and the second fixed frame 20 are hinged to each other so that the folding bed frame can be switched between a folded state and an unfolded state.

[0054] Furthermore, if Figure 4As shown, in the folded state, the first fixed frame 10 and the second fixed frame 20 are staggered in the width direction of the smart bed, and the first fixed frame 10 and the second fixed frame 20 are stacked in the length direction of the smart bed, and the thickness of the first fixed frame 10 and the second fixed frame 20 when stacked is less than the sum of the thickness of the first fixed frame 10 and the thickness of the second fixed frame 20.

[0055] Specifically, the smart bed provided in this embodiment is provided with a folding bed frame, which can be freely switched between a folded state and an unfolded state by relative rotation between the first fixed frame 10 and the second fixed frame 20. In the folded state, the first fixed frame 10 and the second fixed frame 20 are mutually offset in the width direction to avoid each other, and the first fixed frame 10 and the second fixed frame 20 are mutually overlapped in the length direction, and the thickness of the first fixed frame 10 and the second fixed frame 20 when they are overlapped is less than the sum of the thickness of the first fixed frame 10 and the thickness of the second fixed frame 20, that is, the first fixed frame 10 and the second fixed frame 20 are in the state of being unfolded. Figure 4 The mutually embedded state shown not only reduces the thickness after folding, but also ensures the structural strength of the folding bed frame, making it easy to pack and transport.

[0056] For example, Figure 2-Figure 4 As shown, the first fixed frame 10 includes a first crossbar 11 and two first longitudinal bars 12, and the second fixed frame 20 includes a second crossbar 21 and two second longitudinal bars 22. One end of the two first longitudinal bars 12 is hinged to one end of the two second longitudinal bars 22 in a one-to-one correspondence, and the other ends of the two first longitudinal bars 12 are respectively connected to the two ends of the first crossbar 11, and the other ends of the two second longitudinal bars 22 are connected to the two ends of the second crossbar 21. The first crossbar 11 and the second crossbar 21 are both extended along the width direction of the smart bed, and the two first longitudinal bars 12 and the two second longitudinal bars 22 are both extended along the length direction of the smart bed. In the folded state, the first crossbar 11 and the second crossbar 21 are stacked, the first longitudinal bar 12 and the second longitudinal bar 22 are staggered, and the first crossbar 11 and the second crossbar 21 are close to or against each other. Without the staggered setting, the folding thickness of the folding bed frame can be reduced, and the compressive resistance in the thickness direction can be improved.

[0057] Exemplarily, the thickness of the first crossbar 11 is less than the thickness of the first longitudinal bar 12; and / or the thickness of the second crossbar 21 is less than the thickness of the second longitudinal bar 22. The sum of the thicknesses of the first crossbar 11 and the second crossbar 21 is less than the sum of the thicknesses of the first longitudinal bar 12 and the second longitudinal bar 22.

[0058] Exemplarily, the first cross bar 11, the first longitudinal bar 12, the second cross bar 21 and the second longitudinal bar 22 are all made of square tubes. The first cross bar 11 and the second cross bar 21 have the short side direction of the square tube as the thickness direction, and the first longitudinal bar 12 and the second longitudinal bar 22 have the long side direction of the square tube as the thickness direction.

[0059] Preferably, the thickness of the first cross bar 11 is equal to the thickness of the second cross bar 21 , and the thickness of the first longitudinal bar 12 is equal to the thickness of the second longitudinal bar 22 .

[0060] For example, in the width direction of the smart bed, the two first longitudinal rods 12 are located between the two second longitudinal rods 22, or the two first longitudinal rods 12 and the two second longitudinal rods 22 are arranged alternately. Figure 2 and Figure 3 As shown, the two first longitudinal bars 12 are located between the two second longitudinal bars 22 .

[0061] For example, Figure 4-Figure 7 As shown, a first clearance gap 121 is provided at one end of the first longitudinal rod 12 connected to the first crossbar 11, and the first clearance gap 121 is used to avoid the second crossbar 21. A second clearance gap 221 is provided at one end of the second longitudinal rod 22 connected to the second crossbar 21, and the first clearance gap 121 is used to avoid the first crossbar 11. When the folding bed frame is transformed from the unfolded state to the folded state, interference between the first longitudinal rod 12 and the second crossbar 21, and between the second longitudinal rod 22 and the first crossbar 11 is avoided.

[0062] Further, such as Figure 4-Figure 7 As shown, the first clearance gap 121 and the second clearance gap 221 are both set as triangular notch structures, which are formed by obliquely cutting the end of the first longitudinal rod 12 or the second longitudinal rod 22. The first clearance gap 121 and the second clearance gap 221 can be optionally set as an open structure or as Figure 7 The closed structure shown can be formed by incompletely beveling the end of the first longitudinal rod 12 or the second longitudinal rod 22 and then bending the cut portion inwardly into the tube.

[0063] For example, Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the first crossbar 11 is provided with a first mounting hole 101, and the second crossbar 21 is provided with a second mounting hole 201. The first mounting hole 101 and the second mounting hole 201 are both used to install the bed legs. In the unfolded state, the bottom height of the first mounting hole 101 is equal to the bottom height of the second mounting hole 201, and the line connecting the first mounting hole 101 and the second mounting hole 201 is parallel to the length direction of the smart bed, so as to ensure the support reliability of the folding bed frame when it is in the unfolded state. In this embodiment, the first mounting holes 101 are respectively provided at both ends of the first crossbar 11, and the second mounting holes 201 are respectively provided at both ends of the second crossbar 21, and the line connecting the first mounting holes 101 and the second mounting holes 201 correspondingly arranged on the same side is parallel to the length direction of the smart bed.

[0064] For example, Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the first fixed frame 10 also includes a first support rod 14, and the second fixed frame 20 also includes a second support rod 24. The first support rod 14 and the second support rod 24 are both extended along the width direction of the smart bed. The two ends of the first support rod 14 are respectively connected to one end of the two first longitudinal rods 12 close to the second fixed frame 20, and the two ends of the second support rod 24 are respectively connected to one end of the two second longitudinal rods 22 close to the first fixed frame 10. The first support rod 14 supports the bottom of the first bed 70, and the second support rod 24 supports the bottom of the second bed 80.

[0065] For example, Figure 2 , Figure 3 and Figure 6 As shown, the second fixed frame 20 also includes two mounting page plates 25, and the two mounting page plates 25 are respectively connected to the second support rods 24 and / or the two second longitudinal rods 22. The mounting page plates 25 are used to connect and install the bed feet. The bottom surface height of the mounting page plates 25 is equal to the bottom end height of the first mounting hole 101 and the bottom end height of the second mounting hole 201. The connection point between the mounting page plates 25 and the bed feet and the connecting line between the first mounting hole 101 and the second mounting hole 201 are parallel to the length direction of the smart bed.

[0066] For example, Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the first fixed frame 10 further includes a first reinforcing rod 13, which is arranged between the first cross bar 11 and the first support bar 14 along the width direction of the smart bed, and its two ends are respectively connected to the two first longitudinal bars 12. The second fixed frame 20 further includes a second reinforcing rod 23, which is arranged between the second cross bar 21 and the second support bar 24 along the width direction of the smart bed, and its two ends are respectively connected to the two second longitudinal bars 22.

[0067] For example, Figure 2 , Figure 3 and Figure 5 As shown, the first fixed frame 10 also includes a first connecting rod 15, which extends along the length direction of the smart bed, and whose two ends are respectively connected to the first cross bar 11 and the first reinforcing rod 13.

[0068] For example, Figure 2 , Figure 3 and Figure 5 As shown, the first fixed frame 10 also includes a second connecting rod 16, which extends along the length direction of the smart bed, and its two ends are respectively connected to the first supporting rod 14 and the first reinforcing rod 13.

[0069] For example, Figure 2 , Figure 3 and Figure 6 As shown, the second fixed frame 20 also includes a third connecting rod 28, which extends along the length direction of the smart bed, and its two ends are respectively connected to the second cross bar 21 and the second reinforcing rod 23.

[0070] For example, Figure 2-Figure 4 As shown, the folding bed frame also includes a first movable frame 30 and a second movable frame 40, the first movable frame 30 is movably connected to the first fixed frame 10, and the second movable frame 40 is movably connected to the second fixed frame 20; in the folded state, the first movable frame 30 and the second movable frame 40 are staggered in the width direction of the smart bed; and / or in the folded state, the first movable frame 30 and the second movable frame 40 are staggered in the length direction of the smart bed to reduce the overall thickness of the folding bed frame.

[0071] Exemplarily, one end of the first movable frame 30 is hinged to the first reinforcing rod 13, and the other end is suspended and abuts the bottom of the first bed 70. One end of the second movable frame 40 is hinged to the second reinforcing rod 23, and the other end is suspended and abuts the bottom of the second bed 80.

[0072] For example, Figure 1 and Figure 2 As shown, the first bed frame 70 includes a first bed board 71 and a second bed board 72 which are hinged to each other. The first bed board 71 is fixed to the first support rod 14 and the two first longitudinal rods 12 of the first fixed frame 10. The first fixed frame 10 can also support the second bed board 72 through the first cross rod 11 and the two first longitudinal rods 12, and one suspended end of the first movable frame 30 abuts against the bottom of the second bed board 72.

[0073] For example, Figure 1 and Figure 2 As shown, the second bed 80 includes a third bed board 81, a fourth bed board 82 and a fifth bed board 83 which are hinged in sequence, the third bed board 81 is fixed to the second support rod 24 and the two second longitudinal rods 22 of the second fixed frame 20, the second fixed frame 20 can also support the fourth bed board 82 and the fifth bed board 83 through the second cross bar 21 and the two second longitudinal rods 22, and one end of the second movable frame 40 is suspended against the bottom of the fourth bed board 82. The inner side of the second longitudinal rod 22 is also hinged with an oblique support rod 26, and the other end of the oblique support rod 26 is hinged to the fifth bed board 83.
