[0034] Referring to Figures 1, 2 and 3, a cradle bed provided in an embodiment of the present application includes a support structure 10, a bed body 20 and a drive assembly 30. The support structure 10 has a rotating shaft 11, the bed body 20 is connected to the rotating shaft 11, and can swing relative to the support structure 10 around the axis of the rotating shaft 11. The drive assembly 30 is installed on the support member and is used to provide power for the head of the bed 20 to swing around the rotating shaft 11.

[0035] In actual use, a rest space for the baby to rest is formed in the bed 20. When the baby is resting in the bed 20, the driving assembly 30 can be started to swing the bed 20, so that the baby can feel more at ease and fall asleep quickly.

[0036] The bed 20 needs to remain sufficiently stable during the swinging process to avoid shaking that affects the normal rest of the baby in the bed 20. To this end, a plurality of rollers 21 are provided at the bottom of the bed 20. All rollers 21 are used to support the bed 20 to move on the support structure 10. The bed 20 is supported by the plurality of rollers 21, so that the bed 20 is more stable when swinging and is not prone to shaking, so that the baby has a better resting experience in the bed 20. At the same time, supporting the bed 20 by the plurality of rollers 21 is conducive to maintaining the overall flatness of the bottom of the bed 20, so that the bed 20 is not easily deformed even after the cradle bed is used for a long time.

[0037] The above-mentioned cradle bed drives the bed body 20 to swing around the support structure 10 through the driving assembly 30, and while swinging, the bed body 20 is supported on the support structure 10 by a plurality of rollers 21 arranged at the bottom of the bed body 20, so that the swinging process of the bed body 20 is smoother and less likely to shake, thereby ensuring the normal rest of the baby in the cradle bed.

[0038] In some embodiments of the present application, multiple rollers 21 are arranged at circumferential intervals around the rotating shaft 11, the rotation axis of each roller 21 passes through the axis of the rotating shaft 11, and the rotation line of each roller 21 is perpendicular to the axis of the rotating shaft 11. In this way, by controlling the rotation axis of each roller 21 to pass through the axis of the rotating shaft 11, each roller 21 can make a circular motion around the rotating shaft 11, ensuring that all the rollers 21 can roll during the swinging of the bed 20, and the smoothness of the swinging of the bed 20 is ensured by the rolling of the rollers 21 on the support structure 10.

[0039] It is understandable that, in other embodiments, the roller 21 may also be a universal wheel, which can automatically change the direction of its own rotation axis according to the swinging direction of the bed body 20 to adapt to the swinging direction of the bed body 20 .

[0040] Specifically in some embodiments, the roller 21 includes two groups, each group of rollers 21 includes two rollers 21 arranged at intervals along a first direction X, and the two groups of rollers 21 are arranged at intervals along a second direction Y, and the second direction Y intersects with the first direction X, that is, the rollers 21 include four, and the four rollers 21 are respectively arranged on the four corners of the bed 20, and the rotating shaft is arranged in the middle part of the bed 20, so that the middle part of the bed 20 is supported by the rotating shaft, and the four corners of the bed 20 are respectively supported by the four rollers 21, so that the entire bed 20 can be effectively supported, thereby ensuring the overall flatness of the bed 20.

[0041] Each roller 21 is tilted to a certain extent compared to the first direction X and the second direction Y, so that the axis of each roller 21 can pass through the axis of the rotating shaft 11 , thereby allowing the roller 21 to swing together with the bed 20 .

[0042] Specifically in some embodiments, the support structure 10 includes two support frames 12, the two support frames 12 are arranged at intervals along the second direction Y, two support blocks 16 are arranged at intervals along the first direction X on each support frame 12, and each roller 21 is located on one of the support blocks 16. By installing the bed body 20 through two separately arranged support frames 12, the volume of the support structure 10 can be reduced, thereby reducing the floor space of the cradle bed and simplifying the structure of the cradle bed, and the support blocks 16 can provide support for the rotation of the roller 21, ensuring that the roller 21 has a sufficient movement area on the support structure 10.

[0043] Furthermore, the support structure 10 also includes two connecting rods 13, and the two connecting rods 13 are arranged at intervals along the first direction X, and each connecting rod 13 is connected to two support frames 12. The drive assembly 30 and the rotating shaft 11 are both installed on the two connecting rods 13, so that the two support frames 12 are connected to each other through the two connecting rods 13 to form a whole, thereby making the support structure 10 more stable, and the drive assembly 30 and the rotating shaft 11 are supported by the two connecting rods 13, which further simplifies the support structure 10 and makes the support structure 10 easier to transport and install.

[0044] Furthermore, the support structure 10 also includes an annular rod 14, which is arranged around the two support frames 12 and the two mounting rods, and the two ends of the two mounting rods are connected by the annular rod 14. The two mounting rods are connected to each other through the annular rod 14, so that the two annular rods 14 can also form a whole, thereby increasing the stability of the entire support structure 10.

[0045] In some embodiments of the present application, the bed body 20 includes a bed frame 22, a bed guard 23 and a base plate 24. The bed guard 23 is arranged between the base plate 24 and the bed frame 22, and is arranged circumferentially around the base plate 24 and the bed frame 22, so that a rest space for the baby to rest is formed by the bed frame 22, the bed guard 23 and the base plate 24. Rollers 21 are provided on the base plate 24 and are connected to the rotating shaft 11 and the driving assembly 30. The driving assembly 30 drives the base plate 24 to swing, thereby driving the bed body 20 to swing around the rotating shaft 11.

[0046] Among them, the bed guard 23 has elastic force. When the baby is located in the rest space formed by the bed frame 22, the bed guard 23 and the bottom plate 24, the baby will turn over and perform other actions in the rest space. Since the bed guard 23 has elastic force, the baby can be protected when the baby moves. Even if the baby touches the bed guard 23 during the movement, it will not cause damage to the baby.

[0047] In some embodiments, the cradle bed also includes two support rods 15, which are respectively arranged on opposite sides of the bed body 20, and one end of each support rod 15 is connected to the bed frame 22, and the other end is connected to the annular rod 14, that is, the two ends of each support rod 15 are respectively connected to the bed frame 22 and the support structure 10, so that the bed frame 22 is fixed to the support structure 10, so that the bed body 20 and the support structure 10 form a stable connection through the support rods 15, thereby preventing the bed body 20 from falling off the support structure 10.

[0048] It should be noted that the support rod 15 connects the bed frame 22 and the annular rod 14, so that the bed frame 22 remains stationary relative to the supporting structure 10. When the driving assembly 30 drives the base plate 24 to swing, the bed guard 23 is elastic and thus deforms to adapt to the swinging of the base plate 24. Therefore, the bed frame 22 is fixed on the supporting structure 10 and does not affect the swinging of the base plate 24.

[0049] In some embodiments of the present application, the driving assembly 30 is transmission-connected to the bed 20 and is used to drive the bed 20 to swing around the rotating shaft 11, that is, the driving assembly 30 directly drives the bed 20 to swing, while in some other embodiments, the driving assembly 30 can also be used to drive the rotating shaft 11 to rotate, thereby driving the bed to swing through the rotating shaft 11.

[0050] Specifically, the driving assembly 30 includes a power source 31, a first swing rod 32, a second swing rod 33 and a moving block 34. One end of the first swing rod 32 is connected to the power source 31 in a transmission manner, and the other end is rotatably connected to one end of the second swing rod 33. The other end of the second swing rod 33 is rotatably connected to the moving block 34, and the moving block 34 is connected to the bed body 20. In this way, the first swing rod 32, the second swing rod 33 and the moving block 34 form a crank slider mechanism to convert the rotation output by the power source 31 into a linear motion of the moving block 34, thereby driving the bed body 20 to swing around the rotation axis 11 through the moving block 34.

[0051] In some embodiments, the driving assembly 30 further includes a first pulley 35 and a second pulley 36 connected by a belt, the diameter of the first pulley 35 is smaller than the diameter of the second pulley 36, the first pulley 35 is in transmission connection with the power source 31, and the second pulley 36 is in transmission connection with the first swing arm 32. Since the diameter of the first pulley 35 is smaller than that of the second pulley 36, the rotation speed of the first pulley 35 will be lower than that of the second pulley 36, so that the rotation speed of the power source 31 is decelerated and then transmitted to the first swing arm, and finally the bed body 20 is driven to swing. Compared with the traditional gear deceleration method, the deceleration method using the first pulley 35 and the second pulley 36 ensures the deceleration effect while having less noise, which is more conducive to the rest of the baby in the cradle bed.

[0052] Optionally, the power source 31 is a motor, and the voltage input to the motor is adjustable, so that the output speed of the motor can be adjusted by adjusting the voltage of the motor, thereby adjusting the swing speed of the cradle to achieve the swing speed of the cradle required by the user.

[0053] The above cradle bed has at least the following advantages:

[0054] The bed body 20 is driven to swing around the support structure 10 by the driving assembly 30, and while swinging, the bed body 20 is supported on the support structure 10 by a plurality of rollers 21 arranged at the bottom of the bed body 20, so that the swinging process of the bed body 20 is smoother and less likely to shake, thereby ensuring the normal rest of the baby in the cradle.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
