DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] Figure 1 A perspective view of a single-motor baby crib according to an embodiment of the present invention; Figure 2 FIG. 1 is a perspective view of the internal structure of a single-motor baby crib according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, the single-motor baby bed provided by the present invention includes: a bed board 1, a flipping mechanism 2, a vertical lifting mechanism 3, a first frame 4, a second frame 5 and a guardrail 6; wherein, the bed board 1 is arranged on the first frame 4, and the foot of the bed board 1 is pivotally connected to the first frame 4; the first frame 4 can be vertically lifted relative to the second frame 5 through the vertical lifting mechanism 3; the guardrail 6 is connected to the edge of the second frame 5, and the guardrail 6 encloses the bed board 1, the flipping mechanism 2, the vertical lifting mechanism 3, the first frame 4 and the second frame 5; the flipping mechanism 2 is connected to the vertical lifting mechanism 3, and the flipping mechanism 2 follows the movement of the vertical lifting mechanism 3 to drive the bed board 1 to flip relative to the first frame 4.

[0025] In daily life, if the baby is held upright for a while after feeding and then put on the bed, the spitting up of milk will be significantly reduced. We can put the baby on an inclined bed to lie diagonally, and the spitting up of milk will be reduced. The larger the angle of the bed board 1 is, the closer it is to holding the baby upright, and the better the effect of preventing milk from spilling. However, the feeding conditions of babies of different ages should be considered, and it is not advisable to simply pursue a large angle.

[0026] The length and width of the first frame 4 cannot be greater than the length and width of the second frame 5, so as to avoid interference with the guardrail 6 during the lifting process of the first frame. The guardrail 6 is connected to the edge of the second frame 5 and encloses other components inside it. Its height is set according to the body shape of the baby, but it must be higher than the horizontal height of the bed board 1 after tilting, so as to prevent the baby from sliding off the bed board 1 and ensure the safety of the baby. When the vertical lifting mechanism 3 lifts the first frame 4, the flipping mechanism 2 follows the movement to lift the bed board 1, so that the bed board 1 tilts, and vice versa, the bed board 1 is flattened. The flipping angle of the bed board 1 is 0-30°. If the angle is too large, the gap between the bed board 1 and the guardrail 6 will be larger, and it is easy to pinch the baby; preferably 0-10°, which can better ensure the safety of the baby. The flipping mechanism 2 and the vertical lifting mechanism 3 share the same driving device, which reduces the production cost. The vertical lifting mechanism 3 drives the flipping mechanism 2 to move during the lifting process, so that the bed board 1 tilts, simulating a person's vertical holding, achieving the effect of preventing milk spillage, freeing the hands of parents, and saving worry and effort.

[0027] Preferably, a plurality of hollow holes can be added on the bed board 1 for ventilation and air permeability, and also to reduce the overall weight.

[0028] Furthermore, if Figure 2 As shown, the vertical lifting mechanism 3 includes: a first support rod 31, a second support rod 32, a third support rod 33, a fourth support rod 34, a driving cross rod 35 and a straight rod motor 36; wherein, the first support rod 31 is pivotally connected to the second support rod 32 and is in an X shape, the third support rod 33 is pivotally connected to the fourth support rod 34 and is in an X shape, the first support rod 31 is parallel to the fourth support rod 34, and the second support rod 32 is parallel to the third support rod 33; one end of the first support rod 31 and the fourth support rod 34 is pivotally connected to one end of the first frame 4, and the first support rod 31 and the fourth support rod 34 are in parallel. The other end is slidably connected to the other end of the second frame 5, one end of the second support rod 32 and the third support rod 33 are pivotally connected to one end of the second frame 5, and the other ends of the second support rod 32 and the third support rod 33 are slidably connected to the other end of the first frame 4; the two ends of the driving cross rod 35 are respectively vertically connected to the first support rod 31 and the fourth support rod 34, and the horizontal height of the driving cross rod 35 is smaller than the horizontal height of the pivot connection between the first support rod 31 and the second support rod 32; the two ends of the straight rod motor 36 are respectively pivotally connected to the driving cross rod 35 and the other end of the second frame 5.

[0029] The straight rod motor 36 pushes or pulls the driving cross bar 35 to drive the sliding ends of the first support bar 31 and the fourth support bar 34 to slide, and the sliding ends of the second support bar 32 and the third support bar 33 slide accordingly. With the change of the angle between the first support bar 31 and the second support bar 32, and the third support bar 33 and the fourth support bar 34, the horizontal height of the first frame 4 changes accordingly. The two X-shaped components are connected as a whole through the driving cross bar 35, and the mutual support of each part strengthens the overall strength, reduces the risk of tilting, is easy to assemble, and has good stability during lifting.

[0030] Furthermore, if Figure 2 As shown, the other ends of the first support rod 31, the second support rod 32, the third support rod 33 and the fourth support rod 34 are each provided with a first roller 35, and the other ends of the first frame 4 and the second frame 5 are each provided with a guide rail, and the first roller 35 is rotatably arranged in the guide rail.

[0031] The combination of rollers and guide rails is easy to install and maintain, and can also avoid the problem of noise generated by hinges during movement, thereby preventing the baby from being disturbed.

[0032] Furthermore, if Figure 2 As shown, the flipping mechanism 2 includes: a first linkage rod 21, a second linkage rod 22 and a slide groove 23; wherein, a slide groove 23 is respectively provided on the first support rod 31 and the fourth support rod 34; the first linkage rod 21 is parallel to the second linkage rod 22, and the middle parts of the first linkage rod 21 and the second linkage rod 22 are respectively pivotally connected to the first frame 4; one end of the first linkage rod 21 and the second linkage rod 22 are both provided with a second roller 24, and the second roller 24 can roll along the bottom surface of the bed board 1; the other ends of the first linkage rod 21 and the second linkage rod 22 are both slidably connected to the slide groove 23.

[0033] When the vertical lifting mechanism 3 is lifted upward, the first linkage rod 21 and the second linkage rod 22 first move in their respective corresponding chutes 23. At this stage, the second roller 24 has no contact with the bed board 1 until the vertical lifting mechanism 3 is lifted to a certain height. The first linkage rod 21 and the second linkage rod 22 slide to the limit position of the corresponding chutes 23. At this stage, the second roller 24 contacts the bed board 1. As the vertical lifting mechanism 3 continues to be lifted, the chutes 23 push the first linkage rod 21 and the second linkage rod 22 to turn upward with their pivot connection points with the first frame 4 as the rotation axis under the power support provided by the vertical lifting mechanism 3, pushing the bed board 1 to turn over. The second roller 24 rolls on the bed board, so that the bed board 1 tilts to prevent milk from spilling. The mechanism meets the requirements of a single motor drive mechanism, and can also independently change the horizontal height of the bed board 1, which is convenient for splicing the baby bed with the big bed, saving costs and enriching functions.

[0034] Furthermore, if Figure 2 As shown, the first linkage rod 21 and the second linkage rod 22 are both bent toward the head direction of the bed board 1 .

[0035] The bending angle can be designed according to actual needs. The bent first linkage rod 21 and the second linkage rod 22 are conducive to shortening the stroke of the motor and reducing power consumption. Figure 2 As shown, a first push rod 41 is provided on the top of the first frame 4 .

[0036] The first push rod 41 is arranged on the top of the first frame 4 to support the bed board 1 after it is put down, and the number of the first push rods 41 can be selected according to the demand. The first push rod 41 helps to reduce the pressure on the turning mechanism 2 after the bed board 1 is put down, prolongs the life of the turning mechanism 2, and prevents the bed board 1 from shaking.

[0037] Furthermore, if Figure 2 As shown, a second top rod 51 is provided on the top of the second frame 5 .

[0038] The second top rod 51 is arranged at the top of the second frame 5. The second top rod 51 determines the lowest height of the first frame 4. The number of the second top rods 51 can be selected according to the demand. After the first frame 4 is lowered to a certain height, it is supported by the second top rod 51, which replaces the vertical lifting mechanism 3 to bear the force, prolongs the life of the vertical lifting mechanism 3, and prevents the first frame 4 from shaking.

[0039] Further, Figure 3 FIG. 1 is an exploded view of a latch in an embodiment of the present invention, as shown in FIG. Figure 2 and Figure 3 As shown, the guardrail 6 includes: a fixed rail 61 and a side rail 62, and the fixed rail 61 and the side rail 62 are detachably connected.

[0040] There are many ways of detachable connection. For example, the edge of the side rail 62 is provided with a groove for installing the latch 7. The latch 7 is preferably not beyond the surface of the side rail 62 to prevent scratches on the user and improve the appearance. The fixed rail 61 is provided with a latch hole matching the latch, the bottom of the side rail 62 is provided with a male groove 63, and the fixed rail 61 is provided with a female groove 64 matching the male groove 63, which is convenient for disassembly and assembly; only two or more latches 7 can be provided to match the corresponding number of latch holes to fix the side rail 62; buckles 65 can also be used for connection, the top corners of the top of the side rail 62 are respectively provided with a depression, and the depressions are respectively provided with a buckle 65, and the fixed rail 61 and the corresponding positions are respectively provided with a knob 66 ​​matching the buckle 65, the bottom of the side rail 62 is provided with a male groove 63, and the fixed rail 61 is provided with a female groove 64 matching the male groove 63, and after the male groove 63 is inserted into the female groove 64, the buckle 65 is inserted into the knob 66 ​​to complete the connection. While ensuring strength, it is also convenient to remove the side rail 62 at any time, which is convenient for taking care of babies.

[0041] Preferably, the latch 7 comprises: a latch seat 71 and a latch core 72, wherein the latch seat 71 is provided with a slideway running through the latch seat, and the latch core 72 is slidably disposed in the slideway.

[0042] A spring 73 can also be added, and the side walls of the latch seat 71 and the latch core 72 facing each other are provided with mutually matching receiving grooves 74, and the spring 73 is placed in the mutually matching receiving grooves 74, and the length of the receiving groove 74 is greater than the length of the spring 73. The latch core 72 is partially pushed into the latch hole to complete the detachable connection between the side rail 62 and the fixed rail 61, which is simple and quick; the spring 73 can be added for buffering, and plays a buffering role when the latch core 72 squeezes the spring 73, preventing the latch from reaching the limit position and causing a collision sound to disturb the baby.

[0043] Preferably, the knob 66 ​​can be fixed to the fixing bar 61 by using pre-embedded nuts and bolts, which is simple and quick and convenient for quick installation.

[0044] Furthermore, if Figure 2 As shown, a third roller 52 is provided on the bottom surface of the second frame 5 .

[0045] With the help of the third roller 52, the baby crib can be moved without much effort, making it convenient for the baby crib to change its position.

[0046] Furthermore, if Figure 2 As shown, the fixed bar 61 is provided with an emergency stop switch 67 , and the emergency stop switch 67 is electrically connected to the vertical lifting mechanism through a pre-buried wire in the fixed bar 61 .

[0047] When danger occurs, the operation of the crib can be stopped immediately by the emergency stop switch 67 to prevent the baby from being hurt. The pre-buried wire is arranged in the fixed bar 61 and cannot be observed, which ensures the beautiful appearance and can also prevent the baby from contacting the wire, which is safer.

[0048] Preferably, a foot switch is provided on the second frame 5 to facilitate the user to operate it with his foot.
