The crib is bedding designed for the sleeping characteristics of the baby, and generally has higher safety and comfort. Taking the guard bar of the crib as an example, in order to ensure the safety of the baby, the guard bar generally surrounds the crib in the whole circumferential range without leaving gaps, and the height of the guard bar is generally larger than the height of the baby in the kneeling state, so as to prevent the baby from falling off over the guard bar, and in addition, the material of the guard bar is coated with soft material through having round corners, so that the influence on the body of the baby due to the rubbing of the baby and the guard bar is prevented.
Safety is usually the requirement that the crib needs to meet first, and on the basis of meeting the safety of the baby sleeping, the crib is developed with other functions to help people take care of the baby. The most typical function is a moving function, and the baby crib can be flexibly moved by additionally arranging the wheel body at the bottom of the baby crib, so that people can always keep the baby crib in the visual range of the people, and the requirements of a baby can be conveniently responded at any time. Secondly, the height adjustment function also can greatly enhance the convenience of people for looking after the baby, and people tend to adjust the height of the crib to the comfortable range of self-nursing actions under different scenes of feeding, sanitary nursing, outgoing activities and the like.
The existing related crib is often difficult to continuously ensure the safety of the crib when the crib has the functions of movement and height adjustment. Specifically, while the moving function is achieved, the crib often needs to have excellent braking capability or staying capability, so that the crib is maintained in place during the process that a caregiver leaves for a short time, and the safety of the baby carried by the crib is ensured. The brake function of the existing crib is often completed through a brake component which interacts with a wheel body, and the typical brake component comprises a brake rope and a friction piece, and the friction piece is pressed against a corresponding structure on the wheel body through pulling of the brake rope, so that the crib is stopped; in addition, through the cooperation relation between brake block and the brake tooth, set up the brake tooth in the wheel body, control the brake block and with the mutual block of brake tooth through brake rope or other transmission to the locking crib.
The conventional brake assembly provides braking force for the baby crib by depending on the friction between the wheel bodies and the ground, so that the phenomenon that the safety of the baby crib is affected by the skidding of the wheel bodies on uneven, inclined or rainy and snowy road surfaces easily occurs. The existing brake component depends on the active braking action of a guardian of the baby on the crib, namely, the brake component is controlled to actively brake through a button, a pull rod or other modes, when the guardian is lack of alertness or distraction, the control on the crib is easily separated in a state of not actively braking, and further safety accidents are caused.
In addition, the crib with height adjustable function is easy to interfere with the reliability of the brake function structurally, taking the brake form of the conventional manual control brake assembly as an example, no matter the brake handle or the button is pulled or pressed, a transmission assembly with a certain length is required to transmit the brake command from the handle end to the wheel body end, and the transmission assembly designed based on the standard height may have lower sensitivity and operability under different height states, thereby reducing the safety of the crib.

a bed assembly 1;
one end of the support component 2 is connected with the bed body component 1;
the wheel body component 3 is connected to the other end of the supporting component 2; and
the brake component 4 can realize the brake function of the baby crib through the direct contact between the brake component and the ground.
As shown in fig. 2 to 3, the brake assembly 4 can generate friction force in a manner of directly contacting with the ground through itself, rather than indirectly generating friction force with the ground through acting on the wheel body assembly 3, so that the situation that the baby crib is easy to slide due to incapability of braking due to insufficient wheel body grip in a complex environment is avoided.
In addition, as shown in fig. 10, the brake assembly 4 directly contacts with the ground, and an anti-slip pad with a friction force stronger than that of the wheel body material can be arranged in a partial contact area of the brake assembly 4 and the ground, so that the friction coefficient between the crib and the ground is larger, and the safety factor of the crib is improved.
As shown in fig. 4 to 7, as the optimization of any technical solution or any optimized technical solution provided in the foregoing or in the following of the present invention, the brake assembly 4 includes:
the brake seat 41 is arranged on one side of the support component 2 and/or the wheel body component 3 away from the bed body component 1, and the extension length of the brake seat relative to the support component 2 in the direction away from the bed body component 1 is adjustable, so that the baby crib can be in a braking state or an unlocking state respectively; and

a first elastic member 43, one end of which is connected to the brake base 41 and the other end of which is connected to the support assembly 2 and/or the wheel assembly 3, and which can provide an elastic force for the brake base 41 away from the bed assembly 1; and
and the second elastic element 44 is arranged between the brake handle 42 and the bed body assembly 1 and can provide elastic force for the brake handle 42, so that the brake handle 42 has a movement tendency of braking the crib when external force is not applied.
As shown in fig. 13 to 14 and 15 to 16, the first elastic member 43 and the second elastic member 44 may be springs, and are respectively used to position the brake holder 41 and the brake handle 42 corresponding to the braking state of the crib, so that even if a caregiver of an infant forgets to perform a braking operation on the crib in time, the crib can be automatically braked to ensure the safety of the infant.
In the process of automatic braking, the brake base 41 will receive the elastic force from its own weight and the first elastic member 43 at the same time, so as to be attached to the ground in a butting manner, and have a friction force stronger than that under the action of simple gravity.

As shown in fig. 12, the first transmission member 45 having a cylindrical structure and the linkage structure 47 having a circular arc sheet structure can be attached to each other through the respective circular arc peripheral surfaces, and particularly when the baby crib is in a braking state, the inner circular arc of the linkage structure 47 will cover the cylindrical peripheral surface of the first transmission member 45, so that the structure of the brake assembly 4 is more compact.
As shown in fig. 8 to 9, as any technical solution or any optimized technical solution provided in the foregoing or the following paragraphs of the present invention, the second transmission member 46 is a rope-shaped structure, and one end connected to the linkage structure 47 has a stop end with a radius larger than that of the rope-shaped structure, the linkage structure 47 has a pass structure 471 at the first connection point, and the radius of the pass structure 471 is larger than that of the rope-shaped structure and smaller than that of the stop end, so as to provide a pulling force towards the first transmission member only for the second transmission member.
Since the brake holder 41 is to be kept in the braking state by the elastic force of the first elastic member 43, and the brake holder 41 should be kept in the braking state as much as possible for safety reasons, the second transmission member 46 is configured to have a rope-like structure, so that only the force applied by the first transmission member 45 in the pulling direction of the brake holder 41 is transmitted, that is, only in the state requiring unlocking, the brake holder 41 is separated from the ground by pulling close to the second transmission member 46, and in other states, the second transmission member having the rope-like structure will not exert a pressure on the brake holder 41, and thus will not adversely affect the braking performance thereof.
Furthermore, since the second transmission element 46 only needs to provide a pulling force, it can be movably connected to the first transmission element via the linkage structure 47. Specifically, the second transmission element 46 passes through a hole-shaped structure on the linkage structure 47, and a stop end with a radius larger than the radius of the rope-shaped structure and larger than the radius of the hole-shaped structure is arranged at one end of the linkage structure 47, so as to provide a fulcrum for the pulling action of the second transmission element 46.
