[0036] like Figures 1 to 5 As shown, the shock-absorbing bed frame provided in this embodiment includes a bed board structure 1, which includes at least two rotatably connected support plates 11 and a plurality of hinge assemblies 12. Two adjacent support plates 11 are connected by the hinge assembly 12. The hinge assembly 12 includes a hinge 121 and a rubber pad 122. The hinge 121 includes a hinge shaft 1211 and two blades 1212 hinged to the hinge shaft 1211. The two blades 1212 are fixedly connected to the two adjacent support plates 11 in a one-to-one correspondence. The rubber pad 122 is clamped between the blades 1212 and the support plates 11, and the rubber pad 122 separates the blades 1212 and the support plates 11.

[0037] Specifically, the rubber pad 122 has a buffering effect and can absorb part of the impact force. When the user lies on the bed board structure 1, the two adjacent support plates 11 can buffer the user's gravity regardless of whether they are in the same horizontal plane or folded relative to each other to form an angle. Due to the separation effect of the rubber pad 122, no rigid collision will occur between the blade 1212 and the support plate 11, thereby reducing noise.

[0038] In some embodiments, the support plate 11 is made of wood, which is low in cost. In other embodiments, the support plate 11 is made of metal material, such as aluminum alloy or stainless steel, and the hinge 121 is also made of metal material, such as aluminum alloy or stainless steel, so as to enhance the structural strength of the bed board structure 1. In particular, it is known from common sense that when metal parts come into contact with metal parts, electrochemical corrosion is prone to occur under certain conditions, such as in a humid room, thereby shortening the life of the metal parts. In this embodiment, rubber pads 122 are used to insulate and separate the blades 1212 and the support plate 11, which can avoid electrochemical corrosion between the blades 1212 and the support plate 11 and extend the service life of the hinge 121.

[0039] Optionally, a plurality of convex bumps 1221 are provided on a side of the rubber pad 122 that contacts the support plate 11. The convex bumps 1221 contact the support plate 11, which can further provide a buffering effect.

[0040] Optionally, the hinge assembly 12 is located on the side of the support plate 11 away from the user. When the user lies on the bed structure 1, the hinge assembly 12 does not contact the user, does not produce a foreign body sensation, improves comfort, and can prevent the hinge 121 from pinching the user.

[0041] Optionally, the shock-absorbing bed frame further includes a threaded fastener, the support plate 11 is provided with a first connection hole, the rubber pad 122 is provided with a second connection hole 1222, the blade 1212 is provided with a third connection hole 1213, the inner wall of the first connection hole is provided with an internal thread, the threaded fastener passes through the third connection hole 1213 and the second connection hole 1222 in sequence and is threadedly connected to the first connection hole, and the threaded fastener does not completely penetrate the first connection hole. The threaded fastener can stably connect the blade 1212, the rubber pad 122 and the support plate 11; the threaded fastener does not completely penetrate the first connection hole, so that the user is prevented from touching the threaded fastener, and the user will not feel a foreign body when lying on the support plate 11, thereby improving comfort.

[0042] Optionally, the rubber pad 122 and the blade 1212 are penetrated by at least two threaded fasteners, and the distances from the at least two threaded fasteners penetrating the rubber pad 122 and the blade 1212 to the central axis of the hinge shaft 1211 are not equal.

[0043] The more threaded fasteners there are, the stronger the connection strength between the blade 1212, the rubber pad 122 and the support plate 11 is. However, when the number of threaded fasteners is too large, it is inconvenient to disassemble and assemble the hinge assembly 12, and the cost increases. In this embodiment, the distances from the central axis of the hinge shaft 1211 to at least two threaded fasteners that penetrate the rubber pad 122 and the blade 1212 are unequal, ensuring that the blade 1212 can only rotate around the central axis of the hinge shaft 1211 and cannot deviate in other directions. In this embodiment, the threaded fasteners are not shown, the number of threaded fasteners is equal to the number of third connection holes 1213, and the threaded fasteners correspond to the third connection holes 1213 one by one. The blade 1212 is provided with at least two third connection holes 1213, and the distances from the at least two third connection holes 1213 to the central axis of the hinge shaft 1211 are unequal.

[0044] In this embodiment, the rubber pad 122 and the blade 1212 are penetrated by four threaded fasteners, wherein the distance from two threaded fasteners to the central axis of the hinge shaft 1211 is a first preset value, and the distance from the other two threaded fasteners to the central axis of the hinge shaft 1211 is a second preset value, and the first preset value and the second preset value are not equal.

[0045] Optionally, the rubber pad 122 is provided with a limiting groove 1223, and the blade 1212 is accommodated in the limiting groove 1223, and the limiting groove 1223 is used to pre-position the blade 1212. When the blade 1212 is connected to the rubber pad 122, the blade 1212 is accommodated in the limiting groove 1223, and the limiting groove 1223 is used to pre-position the blade 1212 to ensure that the second connection hole 1222 is aligned with the third connection hole 1213 one by one.

[0046] Optionally, a notch 1224 is provided on the side of the limiting groove 1223 facing the hinge shaft 1211, and the blade 1212 extends into the limiting groove 1223 from the notch 1224 to ensure that when two adjacent support plates 11 are in the same horizontal plane, the two blades 1212 are also in the same horizontal plane.

[0047] Optional, such as Figure 1 and Figure 2 As shown, the shock-absorbing bed frame also includes a base 2, a support 3 and a driving member 4. The support 3 is slidably installed on the base 2 in the horizontal direction. One of the base 2 and the support 3 is provided with a guide groove 21, and the other of the two is rotatably installed with a support wheel 31. The support wheel 31 is accommodated in the guide groove 21. The guide groove 21 limits the sliding direction of the support wheel 31. The support wheel 31 is used to support the support 3 to move forward on the base 2, and the bed board structure 1 is laid on the support 3; the base 2 and / or the support 3 are installed with a driving member 4, and the driving member 4 is used to drive the support plate 11 to rotate around the central axis of the hinge shaft 1211.

[0048] In this embodiment, the base 2 is provided with a guide groove 21, and the support 3 is provided with a support wheel 31, and the support wheel 31 supports the support 3 to move on the base 2, thereby driving the bed board structure 1 to move on the support 3. When the posture of the bed board structure 1 needs to be adjusted, the driving member 4 drives the support board 11 to rotate around the central axis of the hinge shaft 1211.

[0049] In some other embodiments, the base 2 is provided with a supporting wheel 31 , and the support 3 is provided with a guiding groove 21 .

[0050] In this embodiment, the base 2 and the support 3 are both equipped with a driving member 4. The driving member 4 on the base 2 and the driving member 4 on the support 3 each drive a supporting plate 11 to rotate.

[0051] Optionally, the support wheel 31 is covered with a rubber sleeve. The rubber sleeve has a buffering effect and can absorb a part of the impact force. When the support wheel 31 moves in the guide groove 21, due to the buffering effect of the rubber sleeve, the noise generated is small.

[0052] The type of driving member can be selected according to actual needs, for example, a motor, a screw drive and a driving rod can be used in combination, or the driving member can be a cylinder.

[0053] In this embodiment, the bed board structure 1 is provided with five support plates 11. In the direction from the head of the bed to the foot of the bed, the five support plates are the first support plate, the second support plate, the third support plate, the fourth support plate and the fifth support plate, respectively.
