Description

Technical Field

[0001] The invention belongs to the technical field of baby products, and in particular relates to an automatic cradle. Background Art

[0002] Traditional cradles generally only have the function of carrying babies. When a newborn baby cries, parents usually hold the baby and rock it slightly at a low frequency to soothe the baby. After the baby stops crying, the baby is put back into the cradle. However, when the baby is in the cradle, it is very likely that the baby will continue to cry because the soothing action of rocking is lost. Based on this, in the cradles in the prior art, the bed and the bed frame are arranged in a rotating connection structure. The bed for carrying the baby can be pushed by the user to rotate slightly back and forth compared to the bed frame, thereby imitating the rocking action of parents holding the baby, so as to soothe the baby on the bed. However, human energy is always limited. In order to optimize the work and rest time of the parents of newborns, most of the cradles provided by the prior art have an automatic rocking function. The user only needs to input a preset mode, and the bed carrying the baby can rock at a preset speed and angle according to the mode requirements.

[0003] A traditional automatic cradle bed includes a base, a rotating base and a bed body. The rotating base is arranged on the base, and the rotating base is driven and connected to the bed body through a rotating shaft. A driving source is arranged in the rotating base, and the driving source drives the rotating shaft to rotate, thereby driving the bed body to reciprocate at a preset frequency and angle. In order to simulate human movements as much as possible, the rotating base in the prior art is generally arranged at the edge of the bed body, and the bed body and the rotating base are eccentrically rotated, that is, the rotating movement area of ​​the bed body is arranged in a conical structure. In actual use, the baby's head or angle basically cannot feel the rotation, so the simulation effect is poor, which may be counterproductive and cause the baby's emotional instability.

[0004] On the other hand, traditional automatic cradle beds are all designed with single-axis support drive. The center of gravity of the bed body is integrated in the rotating shaft. The contact surface between the bed body and the rotating seat will produce a large friction force. When the bed body rotates, it will encounter a large resistance. Therefore, a higher power motor is required. At the same time, a rotating seat with higher structural strength is also required to prevent the structure from collapsing. Based on this, the cost of automatic cradle beds is high and needs to be improved urgently. Summary of the invention

[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. Figures 1 to 9 The described embodiments are exemplary and are intended to be used to explain the embodiments of the present invention, but should not be construed as limiting the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0040] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like 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 embodiments of the present invention can be understood according to specific circumstances.

[0041] In one embodiment of the present invention, Figures 1 to 9 As shown, an automatic cradle bed is provided, comprising a base 100, a rotating assembly 200 and a bed frame support 300; at least two groups of the rotating assemblies 200 are arranged on the base 100, and the ends of the rotating assemblies 200 extend above the base 100; the two ends of the bed frame support 300 are rotatably connected to the active rotating assembly 200 and the driven rotating assembly 200 respectively; wherein a driving source 400 is arranged on the base 100, and the driving source 400 is drivingly connected to one group or all of the rotating assemblies 200.

[0042] In this embodiment, the cradle bed is arranged at the end of the bed frame 300 facing away from the base 100 . The structure of the cradle bed is flexible and is not specifically limited in this embodiment of the present invention.

[0043] Specifically, after the automatic cradle bed is started, the driving source 400 drives the rotating assembly 200 to rotate along a preset angle and speed, and the rotating assembly 200 drives all the rotating assemblies 200 to rotate synchronously through the bed frame 300. The bed frame 300 is driven by the actively rotating rotating assembly 200 and guided by the passively rotating rotating assembly 200 to reciprocate along a preset path to realize the cradle action; compared with the automatic cradle bed in the prior art that uses a single-axis rotating structure as a support and a rotating driving source 400, resulting in a technical problem of insufficient structural stability, the automatic cradle bed provided in the embodiment of the present invention drives the bed frame 300 to reciprocate stably by synchronously rotating at least two groups of rotating assemblies 200. On the one hand, the synchronous driving of multiple groups of rotating assemblies 200 can share the force of the bed frame 300 acting on the rotating assembly 200, reduce the load of the rotating assembly 200, and thereby improve the structural stability of the cradle bed; on the other hand, multiple groups of rotating assemblies 200 serve as rotating supports for the bed frame 300, so that the moving area of ​​the bed frame 300 is not limited to a cone, further improving the soothing effect of the cradle bed.

[0044] like Figure 5 As shown, in another embodiment of the present invention, the rotating end surface between the rotating component 200 and the base 100 is S1, and the rotating end surface between the rotating component 200 and the bed support 300 is S2, S1 and S2 are always arranged in parallel or coplanar, wherein the two ends of the rotating component 200 are eccentrically arranged during rotation.

[0045] If S1 and S2 are misaligned, the rotation paths of the bed support 300 and the rotating assembly 200 will interfere with each other during movement. If the rotation paths at both ends of the rotating assembly 200 are concentrically arranged, the bed support 300 cannot make any movement. Therefore, the parallel or coplanar rotating end face design and the eccentric distribution in this embodiment enable the bed support 300 to move stably along the preset path.

[0046] like Figure 4 As shown, in another embodiment of the present invention, the number of the rotating components 200 is two groups, the connection positions between the two groups of the rotating components 200 and the base 100 are B1 and B2 respectively, the connection positions between the two groups of the rotating components 200 and the bed body are C1 and C2 respectively, the straight-line distance between B1 and C1 is L2, and the straight-line distance between B2 and C2 is L3, wherein L2 and L3 are always parallel.

[0047] Specifically, B1, B2, C1 and C2 are distributed along the endpoints of the parallelogram. During the movement of the bed support 300, the two sets of rotating components 200, the base 100 and the bed support 300 are always distributed in a parallelogram structure, which effectively ensures the smooth movement of the bed support 300. At the same time, the area formed by the movement of the bed support 300 along the deformation path of the parallelogram is arranged in a fan-shaped structure, which is more suitable for emotional comfort for babies than traditional cradles with conical areas.

[0048] like Figures 1 to 9 As shown, in another embodiment of the present invention, the base 100 is provided with a first installation cavity 110, and two groups of connecting seats 120 are provided on the base 100, and the two groups of connecting seats 120 are respectively located at positions B1 and B2, and the driving source 400 is arranged in the first installation cavity 110, and the ends of the rotating components 200 are rotatably connected to the corresponding connecting seats 120, and the driving end of the driving source 400 extends into one group of the connecting seats 120 and is drivingly connected to the rotating components 200. Specifically, based on the stability of the parallelogram, this embodiment only uses a single group of driving sources 400 to drive one group of rotating components 200 to achieve the normal operation of the automatic cradle bed, which will effectively reduce the manufacturing cost of the cradle bed.

[0049] like Figures 1 to 9 As shown, in another embodiment of the present invention, a receiving groove 130 for accommodating the end of the rotating component 200 is provided in the connecting seat 120, and a locking component 500 for locking the rotating component 200 is provided on the side wall of the connecting seat 120, and the driving end of the driving source 400 extends into the receiving groove 130 and is drivingly connected to the rotating component 200.

[0050] In this embodiment, the rotating assembly 200 is limited and locked by the locking component 500 , and the installer can flexibly control the disassembly of the rotating assembly 200 by the locking component 500 , thereby further improving the practicality of the automatic cradle bed.

[0051] like Figures 1 to 9As shown, in another embodiment of the present invention, the locking member 500 includes a slider 510 and an elastic member 520. The end of the slider 510 is slidably connected to the connecting seat 120 and can extend into the receiving groove 130. A U-shaped frame 511 is protrudingly provided at the end of the slider 510. A relief groove 512 for avoiding the movement path of the U-shaped frame 511 is provided in the connecting seat 120. The elastic member 520 is arranged in the relief groove 512. The elastic member 520 is a spring. One end of the elastic member 520 abuts against the inner wall of the U-shaped frame 511, and the other end of the elastic member 520 abuts against the inner wall of the relief groove 512. The other end of the slider 510 extends outside the connecting seat 120. A clamping groove 210 capable of being clamped and adapted to the end of the slider 510 is provided on the side wall of the end of the rotating assembly 200.

[0052] Specifically, an anti-slip pattern 513 is provided at the end of the slider 510 away from the connecting seat 120. Among them, the elastic member 520 always drives the slider 510 to move towards the inside of the connecting seat 120. The user overcomes the elastic force of the elastic member 520 and pulls the slider 510 to make the end of the slider 510 away from the rotating assembly 200 to achieve unlocking. When installing the rotating assembly 200, directly insert the rotating assembly 200 into the connecting seat 120, then release the slider 510. The elastic member 520 drives the slider 510 to reset, and the end of the slider 510 is clamped on the side wall of the rotating assembly 200 to complete locking.

[0053] As Figures 1 to 9 As shown, in another embodiment of the present invention, the drive source 400 is a micro motor.
