[0027] Please see Figures 1 to 3This application provides a crib 100, including a base 10, a crib box 20, and a rocking assembly 30. The crib box 20 is movably mounted on the base 10. The rocking assembly 30 includes a support frame 31, support legs 32, and a rocking member 33. The support frame 31 is fixedly connected to the top of the base 10. The first end of the support leg 32 is fixedly connected to the bottom of the crib box 20 and is disposed outside the support frame 31. One end of the rocking member 33 is rotatably connected to the support frame 31, and the other end is rotatably connected to the second end of the support leg 32. The rocking member 33 is used to drive the support leg 32 to swing relative to the support frame 31, so that the crib box 20 swings relative to the base 10. By connecting the support frame 31 to the base 10, the force-bearing area of ​​the support frame 31 can be increased, making the structure of the support frame 31 more stable. Utilizing the connecting action of the rocking assembly 30, the crib box 20 can be rocked relative to the base 10, realizing the cradle function. By placing the support legs 32 outside the support frame 31, the support frame 31 can be accommodated in the space between the multiple support legs 32, and the crib box 20 and the base 10 are arranged in an upper and lower distribution. This reduces the overall length and width of the crib 100, making the structure of the crib 100 more compact and reducing the space occupied by the entire rocking assembly 30. This also helps to develop and expand other functions of the crib 100, such as setting a climbing ladder 60 around the crib box 20 to enable infants and toddlers to climb and play.

[0028] In some embodiments, the swing member 33 includes a first bearing 331, a second bearing 332, and a first connecting rod 333. The first bearing 331 is connected to the support frame 31, the second bearing 332 is connected to the second end of the support leg 32, and the two ends of the first connecting rod 333 are rotatably connected to the first bearing 331 and the second bearing 332, respectively. The first connecting rod 333 is movable with the first bearing 331 as a fulcrum to drive the support leg 32 to swing. Utilizing the connecting effect of the first connecting rod 333 and the rotatable connection of the first bearing 331 and the second bearing 332, it is possible to achieve a swing with the support frame 31 (base 10) as a fixed member (with the ground as a reference frame), the first bearing 331 as a swing fulcrum, and the first connecting rod 333 swinging around the first bearing 331 with its own length as a radius, thereby driving the support leg 32 to move. Figure 4 As shown, the dashed line trajectory is the swing trajectory of the support leg 32, which realizes the swinging action of the bed box 20 relative to the base 10, thereby realizing the cradle function of the crib 100.

[0029] In some embodiments, the support frame 31 and the base 10 are spaced apart to form an active space 311. The swing member 33 is housed in the active space 311. The first bearing 331 is located above the second bearing 332 along the direction of gravity. A portion of the support leg 32 extends into the active space 311 and swings within it. By raising the support frame 31 a certain height away from the base 10, an active space 311 is formed between them, allowing the support leg 32 to swing within it and preventing collisions or interference between the support leg 32 and other components. The extension of a portion of the support leg 32 into the active space 311 reduces the distance between the crib box 20 and the base 10, minimizing the space occupied by the support leg 32 and making the overall structure of the crib 100 more compact. By placing the second bearing 332 below the first bearing 331, the weight of the bed box 20 is concentrated on the second bearing 332. Therefore, the first bearing 331, the first connecting rod 333 and the second bearing 332 can form a structure with the center of gravity pointing downward, which improves the stability of the swinging component 33 during operation.

[0030] Optionally, the rocking assembly 30 also includes several pillars 34, one end of which is connected to the support frame 31 and the other end is connected to the top of the base 10, so that the support frame 31 is raised a certain distance away from the base 10 and an active space 311 is formed between them.

[0031] In some embodiments, the swing member 33 includes at least a pair of first bearings 331 and second bearings 332, and at least a plurality of first connecting rods 333. The swing member 33 also includes a second connecting rod 334 and a third connecting rod 335. The outer rings of the two first bearings 331 are fixedly connected to the support frame 31. The two ends of the second connecting rod 334 pass through the inner rings of the two first bearings 331, respectively. The outer rings of the two second bearings 332 are fixedly connected to the second ends of the support legs 32, and the two ends of the third connecting rod 335 pass through the inner rings of the two second bearings 332, respectively. The plurality of first connecting rods 333 are arranged in parallel, with one end of the first connecting rod 333 connected to the second connecting rod 334 and the other end connected to the third connecting rod 335. By arranging the first bearings 331 and second bearings 332 in pairs, at least two support points can be formed in the length or width direction of the crib 20, thereby improving the stability and balance of the crib 20 during the swinging process and improving the reliability and safety of the crib 100 during use. Therefore, multiple first connecting rods 333 can connect multiple first bearings 331 and second bearings 332 to form a swingable structure. Utilizing the mutual rotation between the inner and outer rings of the bearings, the support frame 31, first connecting rods 333, and support legs 32 can achieve mutual swinging. Two first bearings 331 are connected by a second connecting rod 334, and two second bearings 332 are connected by a third connecting rod 335. This creates a rectangular frame structure, simplifying the connection between the multiple first bearings 331 and the multiple second bearings 332, and also improving the connection strength and stability between the first bearings 331 and the second bearings 332.

[0032] For example, the outer ring of the first bearing 331 can be welded to the support frame 31, and the outer ring of the second bearing 332 can be welded to the second end of the support leg 32.

[0033] In some embodiments, the swing member 33 includes two pairs of first bearings 331 and second bearings 332. The support frame 31 is a rectangular frame. The two pairs of first bearings 331 are respectively disposed on two opposite sides of the support frame 31. The length of the third link 335 is greater than the length of the second link 334. The first link 333 is perpendicular to the second link 334. The second link 334, the third link 335, and the support frame 31 are arranged parallel to each other. By distributing the two pairs of first bearings 331 on two opposite sides of the support frame 31, the first bearings 331 are basically distributed at the four corners of the rectangle, which helps to improve the force balance of the support frame 31. Correspondingly, the bottom surface of the bed box 20 can also be rectangular. The four support legs 32 are four in number and are respectively disposed at the four corners of the bottom surface of the bed box 20. The area enclosed by the support frame 31 is slightly smaller than the bottom area of ​​the bed box 20, so that the four support legs 32 are located on the outside of the support frame 31. In this way, the rocking assembly 30 can be set as two identical rocking members 33, with the two rocking members 33 spaced apart along the width direction of the bed box 20. The support legs 32 connected to the two ends of the same long side of the bottom surface of the bed box 20 are movably connected to the support frame 31 through the same rocking member 33, so that the bed box 20 can swing along the axis of rotation, and the direction of the axis of rotation is parallel to the length direction of the bed box 20.

[0034] Optionally, the support leg 32 can be detachably connected to the crib box 20, for example, by bolts. This facilitates the disassembly, packaging and transportation of the crib 100, and makes it easy to assemble the crib 100 before use.

[0035] It is understood that the swinging of the bed box 20 in this application can be achieved by pushing the bed box 20 by hand, or by setting an electric mechanism (such as a motor) to drive the bed box 20 or the swinging component 30, without specific limitations here.

[0036] In some embodiments, the crib 100 further includes a locking assembly 40 connected to the crib frame 20 and the base 10, which is used to lock the relative movement between the crib frame 20 and the base 10. By using the locking assembly 40, the relative movement between the crib frame 20 and the base 10 can be locked, thereby fixing the crib frame 20 in place and facilitating the switching of the crib 100 to a normal use mode other than the cradle mode. Alternatively, when the crib 100 can be switched to stroller mode, locking the crib frame 20 facilitates the use of the crib 100 as a stroller.

[0037] In some embodiments, please refer to Figure 5The locking assembly 40 includes a locking pin 41 and a locking rod 42. The locking pin 41 is located on the side of the bed box 20 perpendicular to the rotating shaft of the first bearing 331. The locking rod 42 is rotatably connected to the base 10. The locking rod 42 is provided with a hook 421. The locking rod 42 is used to lock the bed box 20 when it is rotated until the hook 421 engages with the locking pin 41, and to release the locking of the bed box 20 when it is rotated until it is separated from the locking pin 41. By utilizing the engaging action of the locking pin 41 and the locking rod 42, the locking rod 42 can fix the relative angle between the bed box 20 and the base 10, thereby preventing the bed box 20 from swinging and achieving the effect of locking the bed box 20. The locking method of using the locking rod 42 to rotate and engage with the locking pin 41 simplifies the locking or unlocking operation and improves the convenience of operation. When it is necessary to release the bed box 20 from the lock, rotate the locking lever 42 in the direction away from the opening of the hook 421, and the locking pin 41 is released from the hook 421, and the bed box 20 returns to the swingable state.

[0038] Optionally, two sets of locking components 40 can be provided. The locking pins 41 in the two sets of locking components 40 are spaced apart on the side of the bed box 20, and the two locking rods 42 are also spaced apart on the base 10. When the locking rods 42 are engaged with the locking pins 41, the two locking rods 42 are arranged in parallel.

[0039] In some embodiments, the base 10 includes two base plates 11 spaced apart vertically, with a storage space 111 formed between the two base plates 11. The rocking assembly 30 is disposed on the upper base plate 11. By spaced apart, the two base plates 11 provide a storage space 111, thereby increasing the storage capacity of the crib 100. Optionally, a storage box 112, a storage basket, or a storage bag can be installed in the storage space 111. The storage box 112 can be detachably connected to the lower base plate 11, which helps to improve the storage effect.

[0040] In some embodiments, the crib 100 further includes a lifting assembly 50 and a ladder 60. The lifting assembly 50 is connected between two base plates 11 and is telescopically adjustable to change the distance between the two base plates 11. One end of the ladder 60 is connected to the crib box 20, and the other end is connected to the lower base plate 11. Alternatively, the other end of the ladder 60 may rest on the ground. Adjusting the distance between the two base plates 11 using the lifting assembly 50 allows for height adjustment of the crib box 20 to meet practical needs and reduce the degree of bending for parents. Furthermore, increasing the distance between the base plates 11 raises the crib box 20, thereby increasing storage space 111. The ladder 60 also meets the needs of children climbing and playing; therefore, adjusting the height of the crib box 20 adjusts the climbing height to meet play needs. Optionally, the ladder 60 may also be telescopic, allowing its length to be adjusted according to the actual height of the crib box 20.

[0041] Optionally, the side of the bed frame 20 with the ladder 60 may have an opening 21, which allows children to climb in or out of the bed frame 20. A storage bag 22 may also be provided on the side of the bed frame for storing personal belongings.

[0042] In some embodiments, the crib 100 further includes casters 71, a push-pull handle 72, and a screen 73. The casters 71 are disposed on the bottom plate 11, the push-pull handle 72 is disposed on the outer periphery of the crib frame 20, and the screen 73 is foldable and disposed on the crib frame 20. The casters 71 enable the crib 100 to slide as a whole, thus allowing the crib 100 to function as a stroller, making it easy to push or push the crib 100 outdoors. Therefore, the push-pull handle 72 makes it easy for the user to push the crib 100. The screen 73 can be a light-blocking screen, a mosquito net for preventing mosquitoes, or a dust cover, meeting the usage needs of the crib in various scenarios. Making the screen 73 foldable allows it to cover the crib frame 20 when unfolded and to be folded when not in use, thereby improving the practicality of the crib 100.

[0043] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
