[0034] In modern society, people are increasingly concerned about children's growth, leading to a proliferation of automatic sleep-aid products. Common sleep-aid products include rocking beds, which rock side to side to help infants and young children quickly fall asleep. Current rocking beds use a boom connecting the uprights and bed frame. When the boom swings around the uprights, the bed frame follows. However, the existing boom's pivoting structure creates significant resistance, making it difficult to move the bed frame, resulting in poor user convenience.

[0035] To solve the above problems, refer to Figures 1 to 3 In an embodiment of the present invention, a rocking bed includes a column 100, a suspension rod 110, and a bed frame 120. One end of the suspension rod 110 is pivotally connected to the column 100, and the other end is pivotally connected to the bed frame 120, so that the bed frame 120 can swing relative to the column 100. It is understood that at least two suspension rods 110 are provided on the column 100, and the two suspension rods 110 are located on both sides of the column 100, so that the bed frame 120 can swing smoothly relative to the column 100.

[0036] Reference Figure 4It can be understood that the two ends of the suspension rod 110 are respectively provided with a first pivot member 103 and a second pivot member 116. The suspension rod 110 includes a first end 111 and a second end 112. The first pivot member 103 is fixedly installed on the first end 111, the second pivot member 116 is fixed on the bed frame 120, and the second end 112 is pivotally connected to the second pivot member 116. Furthermore, the boom 110 also includes a main body 118, a first end 111 and a second end 112 are respectively located at both ends of the main body 118, and the length direction of the main body 118 extends along the height direction of the column 100, and the first end 111 extends in the horizontal direction, so that the first end 111 and the first pivot member 103 are inserted into the column 100 together and rotate together relative to the column 100, and the second end 112 extends in a direction away from the first end 111 and is parallel to the extension direction of the first end 111, that is, the bed frame 120 is located on the other side of the boom 110 away from the column 100, so that a sufficient distance is maintained between the bed frame 120 and the column 100 to avoid interference when the bed frame 120 swings.

[0037] It is understood that the column 100 is provided with a fixing base 101, which defines a mounting cavity 102 therein, and the first pivot member 103 is rotatably connected to the mounting cavity 102. Furthermore, the outer peripheral wall of the first pivot member 103 is provided with a plurality of ribs 104 that abut against the inner wall of the mounting cavity 102. The contact between the ribs 104 and the inner wall of the mounting cavity 102 can reduce the contact area between the first pivot member 103 and the fixing base 101, thereby reducing rotational resistance.

[0038] Reference Figure 4 It is understood that the arrangement of several ribs 104 along the axis of the first pivot member 103 at intervals helps improve pivot stability. Furthermore, the ribs 104 extend around the periphery of the first pivot member 103, forming a ring shape. This allows the outer circumferential walls of the ribs 104 to maintain contact with the inner walls of the mounting cavity 102 when the first pivot member 103 rotates relative to the fixed base 101. This stabilizes pivoting while reducing the contact area between the first pivot member 103 and the fixed base 101, thereby lowering rotational resistance and facilitating swinging of the boom 110. Furthermore, the fixed base 101 is provided with a stopper 1011. The stopper 1011 is located on the side of the mounting cavity 102 near the main body 118 and extends radially along the first pivot member 103. This prevents the first pivot member 103 from falling off the fixed base 101 during rotation, thereby improving movement stability.

[0039] It can be understood that the second pivot 116 is fixed to the bed frame 120, and the second end 112 can rotate relative to the second pivot 116. Specifically, the inner wall of the second pivot 116 is provided with a plurality of convex ribs 105 abutting the outer peripheral wall of the second end 112, which can reduce the contact area between the second pivot 116 and the second end 112, thereby reducing the rotation resistance, reducing the swing resistance of the boom 110 and the bed frame 120, saving labor when pushing the bed frame 120, and improving the use experience and convenience.

[0040] It can be understood that the first pivot 103 is made of polyoxymethylene resin, that is, POM / plastic steel material, which has high strength and good lubricity, and can reduce the friction resistance during rotation. In some embodiments, the first pivot 103 and the second pivot 116 are both made of polyoxymethylene resin, which is beneficial to further reduce the rotation resistance.

[0041] In some embodiments, the first pivot 103 is fixed in the fixed seat 101, the first end 111 is pivotally connected in the first pivot 103, and the rib 104 is arranged in the inner wall of the first pivot 103 and abuts the radial outer wall of the first end 111, so as to reduce the contact area between the first pivot 103 and the first end 111 and reduce the rotation resistance.

[0042] It can be understood that the second pivot 116 is provided with a connecting hole 109 for inserting the second end 112, the inner wall of the connecting hole 109 has a taper, and the outer peripheral wall of the second end 112 on the boom 110 is in taper surface cooperation with the inner wall of the connecting hole 109, that is, after the second end 112 is inserted into the second pivot 116, the axial position is limited by the taper surface cooperation, which avoids the axial deviation of the second end 112 during rotation in the connecting hole 109, and is beneficial to maintaining the movement stability of the bed frame 120.

[0043] It can be understood that a plurality of convex ribs 105 are arranged in the connecting hole 109 along the circumference of the second end 112, and the plurality of convex ribs 105 are arranged in pairs and symmetrically with respect to the axial direction of the second end 112, the convex ribs 105 protrude from the radial inner wall of the connecting hole 109 to the direction of the second end 112, and the convex ribs 105 extend along the axial direction of the second end 112, which can reduce the contact area between the connecting hole 109 and the boom 110, thereby achieving the effect of reducing the rotation resistance. It can be understood that the taper surface of the connecting hole 109 is arranged on the convex ribs 105, which can enable the second end 112 to stably contact the second pivot 116. In this embodiment, the convex ribs 105 are provided with eight, which can reduce the contact area while maintaining the stability of the contact.

[0044] Referring to Figure 5 and Figure 6As can be understood, two fasteners 106 are disposed within the second pivot member 116, and the two fasteners 106 are symmetrically arranged. A fastening groove 113 is disposed on the outer peripheral wall of the second end 112. The fastening groove 113 is disposed about the axis of the second end 112, and the fasteners 106 are capable of being inserted into the fastening groove 113. Specifically, the fastener 106 includes an elastic portion 107 and a fastening portion 108. The fastening portion 108 protrudes from the elastic portion 107 toward the second end 112 and is capable of being inserted into the fastening groove 113. The elastic portion 107 is capable of elastically deforming in the radial direction of the second end 112. As can be understood, one end of the elastic portion 107 is fixedly connected to the second pivot member 116, and the other end is free, allowing the section of the elastic portion 107 where the fastening portion 108 is disposed to be elastically deformable. When the second end 112 is inserted into the connection hole 109, it pushes the snap-fit ​​portion 108 to move radially outward. When the snap-fit ​​portion 108 is inserted into the snap-fit ​​groove 113, the elastic portion 107 rebounds, thereby stably inserting the snap-fit ​​portion 108 into the snap-fit ​​groove 113 and achieving the installation connection between the second end 112 and the second pivot member 116. Furthermore, the snap-fit ​​groove 113 is oriented around the axis of the second end 112, so that when the second end 112 rotates relative to the second pivot member 116, it will not be blocked by the snap-fit ​​portion 108. In other embodiments, only one snap member 106 may be provided in the second pivot member 116.

[0045] Furthermore, the second end 112 is provided with a stopper 115 and a neck 114. The minimum outer diameter of the stopper 115 is greater than the maximum outer diameter of the neck 114, meaning that the bottom wall of the snap-fit ​​groove 113 is the radially outer circumferential wall of the neck 114. It is understood that the stopper 115 is located at the end of the second end 112 facing away from the main body 118, while the snap-fitting portion 108 is located outside the neck 114 and, along the extension direction of the second end 112, on the side of the stopper 115 closer to the neck 114. The stopper 115 prevents the second end 112 from slipping out of the connecting hole 109, thereby ensuring a stable connection between the suspension rod 110 and the second pivot member 116. Furthermore, a curved surface 117 is provided at the end of the stopper 115 facing away from the snap-fitting groove 113. When the second end 112 is inserted into the connecting hole 109, the curved surface 117 pushes the snap-fitting portion 108 outward in the radial direction of the second end 112, thereby reducing installation resistance and improving installation convenience.

[0046] It is understandable that the rib 105 is at least partially located on the surface of the fastener 106 facing the fastening groove 113, which can achieve stable pressure contact between the rib 105 and the second end 112. Figure 7As will be appreciated, the ribs 105 are arranged symmetrically about the axis of the second end 112, enabling the second end 112 to rotate about its axis, preventing eccentricity during rotation and thereby improving pivoting stability. As will be appreciated, the presence of eight ribs 105 along the circumference of the second end 112 reduces rotational resistance while improving rotational stability.

[0047] Reference Figure 8 It is understood that the bed frame 120 includes a bottom bar 121, and the second pivot member 116 is fixed to the bottom bar 121. Furthermore, the second pivot member 116 is provided with a mounting portion 1161 fixedly connected to the bottom bar 121. The mounting portion 1161 has a mounting slot 1162 for receiving the bottom bar 121, and the mounting slot 1162 extends along the length of the bottom bar 121. The mounting slot 1162 has a clamping portion 1163 on each side that abuts the outer wall of the bottom bar 121. The two clamping portions 1163 extend in a direction perpendicular to the length of the bottom bar 121. The two clamping portions 1163 abut the outer wall of the bottom bar 121 to constrain the bottom bar 121 within the mounting slot 1162, thereby achieving fixed installation of the second pivot member 116 on the bottom bar 121. It is understood that the bottom bar 121 is configured as a circular tubular member, and the distance between the outer wall of each latch portion 1163 on the mounting groove 1162 and the bottom wall of the mounting groove 1162 is greater than the radius of the bottom bar 121. This allows the bottom wall of the mounting groove 1162 to wrap over more than half of the outer circumference of the bottom bar 121, preventing the bottom bar 121 from separating from the mounting groove 1162 and improving connection stability. It is understood that the mounting portion 1161 and the mounting groove 1162 are located above the connecting hole 109, and the second end 112 is inserted into the connecting hole 109. The second end 112 extends horizontally, thereby connecting the second end 112 to the bottom bar 121, achieving a stable connection between the bed frame 120 and the suspension rod 110. In other embodiments, only one side of the mounting groove 1162 may have a latch portion 1163 that abuts the outer wall of the bottom bar 121.

[0048] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
