Detailed ways

The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in FIGS. 1 to 9 , the child bed of the present invention has an unfolded state and a folded state. The child bed includes an upper frame assembly 1 , a chassis assembly 2 , and a plurality of upright pole assemblies arranged between the upper frame assembly 1 and the chassis assembly 2 .

The upper enclosure assembly 1 includes a plurality of enclosure rod assemblies arranged circumferentially, each enclosure rod assembly is arranged at a different side of the upper enclosure assembly, and a vertical rod assembly is arranged between each two adjacent enclosure rod assemblies. In this embodiment, the enclosure rod assemblies are arranged at the front and rear sides and the left and right sides of the upper enclosure assembly 1, and four vertical rod assemblies are arranged, which are respectively located at the four corners of the upper enclosure assembly 1.

Each enclosure rod assembly includes two enclosure rods 11 and a connecting member 12 connected between the two enclosure rods 11. The axis lines of the two enclosure rods 11 extend in the same straight line direction, and the axis line of the enclosure rod 11 is the axis line of the enclosure rod assembly. One end of each enclosure rod 11 can be rotatably arranged relative to an adjacent vertical rod assembly around a first axis 41, and the other end of each enclosure rod 11 is rotatably connected to a corresponding end of the connecting member 12 via a second axis 42. Each enclosure rod assembly can also be rotatably arranged relative to the two adjacent vertical rod assemblies around its own axis.

When the child bed is in the unfolded state, the chassis assembly 2 is located below the upper frame assembly 1. The chassis assembly 2 includes a base 21 located at the center of the bottom of the child bed and a plurality of bottom support assemblies with one end rotatably connected to the base 21, and the other end of each bottom support assembly is rotatably connected to a different vertical rod assembly. In this embodiment, the number of bottom support assemblies is the same as that of vertical rod assemblies, and both are provided with four groups. The four bottom support assemblies are connected to the base 21 to form an "X"-shaped structure.

The bottom support assembly includes a first bottom support rod 22 and a second bottom support rod 23 located below the first bottom support rod 22. The two ends of the first bottom support rod 22 are rotatably connected to the base 21 and the lower part of the vertical pole assembly respectively. The two ends of the second bottom support rod 23 are rotatably connected to the base 21 and the lower part of the vertical pole assembly respectively.

In this embodiment, the first bottom support rod 22 and the second bottom support rod 23 are arranged in parallel.

The plurality of vertical pole assemblies are respectively a first vertical pole assembly 3a and a plurality of second vertical pole assemblies 3b except the first vertical pole assembly 3a. The first vertical pole assembly 3a and the second vertical pole assembly 3b each include a rod body 31 extending in the up-down direction, a top angle 32 fixedly arranged at the upper end of the rod body 31, and a bottom angle 33 fixedly arranged at the lower end of the rod body 31, one end of each of the frame rods 11 can be rotatably arranged relative to the top angle 32, and the other end of each of the first bottom support rod 22 and the second bottom support rod 23 is rotatably connected to the bottom angle 33.

The child bed also includes a locking structure for locking the child bed in an unfolded state, and the locking structure includes a first locking structure for locking each surrounding frame rod assembly in an unfolded state, and the first locking structure is respectively arranged between each surrounding frame rod 11 and the connecting member 12 of each surrounding frame rod assembly. The first locking structure has a locked state and an unlocked state. When the child bed is in an unfolded state, the first locking structure is in a locked state, and the relative positions of the surrounding frame rod assemblies are locked by the first locking structure, so that the upper surrounding frame assembly is kept in a stable unfolded state; when the first locking structure is unlocked, the two surrounding frame rods 11 of each surrounding frame rod assembly can be relatively rotated and brought close.

Specifically, the first locking structure includes a stopper 121 disposed on the connecting member 12. When the first locking structure is in a locked state, the stopper 121 blocks the rotation path of the enclosure rod 11 rotating around the first axis 41, so that the two enclosure rods 11 on one enclosure rod assembly cannot rotate relative to each other and retract. When the first locking structure is in an unlocked state, the stopper 121 is away from the rotation path of the enclosure rod 11 rotating around the first axis 41, and the two enclosure rods 11 on one enclosure rod assembly can rotate relative to each other and retract.

Specifically, when the first locking structure is in the locked state, the stopper 121 blocks the upper part of the enclosure rod 11, and when the stopper 121 leaves the upper part of the enclosure rod 11, the first locking structure is unlocked. In this embodiment, when the first locking structure is in the unlocked state and the enclosure rod assembly is not folded, the stopper 121 is located below the enclosure rod 11.

When the first locking structure is in a locked state and causes the frame rod assembly to rotate around its own axis relative to the adjacent vertical rod assembly, the blocking portion 121 can be moved away from the rotation path of the frame rod 11 around the first axis 41, thereby unlocking the first locking structure; and when the frame rod assembly is unfolded and the first locking structure is in an unlocked state, causing the frame rod assembly to rotate in the opposite direction around its own axis relative to the adjacent vertical rod assembly, the blocking portion 121 can be again blocked on the rotation path of the frame rod 11 around the first axis 41, thereby locking the first locking structure.

When at least one enclosure rod assembly rotates around its own axis, the linkage mechanism can drive the remaining enclosure rod assemblies to rotate around their own axis, that is, the first locking structure on each enclosure rod assembly can be locked and unlocked at the same time.

This embodiment provides a specific implementation method in which when one enclosure rod assembly rotates about its own axis, the linkage mechanism drives the remaining enclosure rod assemblies to rotate about their own axis, so that the first locking structure on each enclosure rod assembly can be locked and unlocked at the same time.

Specifically, except for the first vertical pole assembly 3a, each second vertical pole assembly 3b is provided with a linkage mechanism. The linkage mechanism includes two bevel gears 5, which are respectively arranged on both sides of the top corner 32 of the second vertical pole assembly 3b, and the two bevel gears 5 are meshed with each other. The ends of two adjacent enclosure rod assemblies, i.e., one end of the enclosure rod 11, are rotatably connected to the bevel gear 5 on the corresponding side through the first shaft 41. The two bevel gears 5 are rotatably arranged on the top corner 32 of the second vertical pole assembly 3b around the axis of the enclosure rod assembly connected thereto.

In this way, at least one bevel gear 5 is connected to a frame rod assembly. When a frame rod assembly rotates around its own axis, it can drive the bevel gear 5 connected to it to rotate synchronously around the axis of the frame rod assembly relative to the vertex angle 32, so that the bevel gear 5 meshing with the bevel gear 5 can drive the frame rod assembly connected to it to rotate around the axis of the frame rod assembly. In this way, all the frame rod assemblies drive the bevel gears 5 connected to them to rotate around their own axis relative to the vertex angle. When the frame rod assembly is folded, the frame rod 11 rotates around the first axis 41 relative to the bevel gear 5.

The upper enclosure assembly also includes an adapter 6, which is respectively arranged on both sides of the top corner 32 of the first vertical pole assembly 3a, and one end of two adjacent enclosure rod assemblies, i.e., enclosure rods 11, are both rotatably arranged on the adapter 6 on the corresponding side around their own axis, and both adapters 6 are rotatably connected to the top corner 32 of the first vertical pole assembly 3a through the first axis 41. When the first locking structure is locked or unlocked, the enclosure rod assembly rotates around its own axis relative to the adapter 6, and when the enclosure rod assembly is folded, the adapter 6 drives the enclosure rod 11 to rotate around the first axis 41 relative to the top corner 32 of the first vertical pole assembly 3a.

The child bed also includes a handle 7 for driving a surrounding frame rod assembly to rotate around its own axis, and the handle 7 is fixedly arranged on a surrounding frame rod 11. The handle 7 is used for manual operation when the first locking structure is unlocked or locked, so that the surrounding frame rod assembly connected to it is driven to rotate around its own axis by pulling the handle 7. By providing the handle 7, it is convenient for people to operate to lock or unlock the first locking structure.

In this embodiment, the handle 7 is disposed on a frame rod 11 connected to the first vertical rod assembly 3 a , and the handle 7 is located on the frame rod 11 at an end portion close to the first vertical rod assembly 3 a .

Of course, when two enclosure rod assemblies rotate around their own axis, the linkage mechanism can drive the remaining enclosure rod assemblies to rotate around their own axis, so that the first locking structure on each enclosure rod assembly can be locked and unlocked at the same time. In this case, the linkage mechanism is arranged on two diagonally arranged vertical rod assemblies, and when unlocking, the two oppositely arranged enclosure rod assemblies are driven to rotate around their own axis.

The locking structure also includes a second locking structure for locking the chassis assembly 2 in the unfolded state. The second locking structure has a locked state and an unlocked state. When the child bed is in the unfolded state, the second locking structure is in the locked state, and the relative position of the chassis assembly 2 is locked by the second locking structure to keep it in a stable unfolded state; when the second locking structure is unlocked, each of the first bottom support rod 22 and the second bottom support rod 23 rotates relative to the base 21 and moves closer. The specific structure of the second locking structure and the structure for driving the second locking structure to unlock can both adopt the structure in the prior art.

When the child bed is in an unfolded state, the first locking structure and the second locking structure are both in a locked state, and the upper frame assembly 1 and the chassis assembly 2 are both in an unfolded state, as shown in FIGS. 1 and 2 .

When the child bed needs to be folded, the handle 7 is pulled, and the handle 7 drives a frame rod assembly connected to it to rotate around its own axis, and drives the bevel gear 5 arranged at the end of the frame rod assembly to rotate synchronously relative to the top angle 32, so that the other bevel gear 5 meshing with the bevel gear 5 also rotates relative to the top angle 32, thereby driving a frame rod assembly connected to the other bevel gear 5 to rotate around its own axis, so that the bevel gear 5 arranged at the other end of the frame rod assembly rotates synchronously, ... and so on, until all the frame rod assemblies and the bevel gears 5 connected thereto rotate around their respective axis centers relative to the top angle 32 at the same time, so that the first locking structures on each frame rod assembly are unlocked at the same time; the second locking structure is unlocked; after the first locking structure and the second locking structure are unlocked, the upper frame assembly 1 and the chassis assembly 2 can be folded. When folding, the base 21 is pulled upward to make the base 21 move upward. When the base 21 moves upward, each of the first bottom support rods 22 and the second bottom support rods 23 rotates relative to the base 21 and moves closer. At the same time, the frame rods 11 of the frame rod assembly rotate downward relative to the bevel gear 5 and/or the top angle 32 around the first axis 41 so that the two frame rods 11 of each frame rod assembly move closer together, so that each upright rod assembly moves closer to the center of the child bed. The folding process is shown in Figures 6 and 7. Until each upright rod assembly, the upper frame assembly 1 and the chassis assembly 2 are closely together, the final folding is shown in Figures 8 and 9. The folded child bed has a compact structure and a small volume, which is easy to carry and store.

When the child's bed is unfolded from the folded state, the base 21 is pressed downward to move it downward, so that the first bottom support rod 22 and the second bottom support rod 23 rotate and unfold relative to each other. At the same time, the two frame rods 11 of each frame rod assembly rotate and unfold relative to each other, so that each upright rod assembly moves toward the outside of the child's bed until the base 21 moves downward to the unfolded position, the second locking structure is locked, the upper frame assembly 1 is also unfolded, and the handle 7 is rotated in the opposite direction to drive a frame rod assembly connected to it to rotate in the opposite direction around its own axis and reset. Through each linkage mechanism, the remaining frame rod assemblies are driven to rotate in the opposite direction around their own axis relative to the top angle 32 and reset at the same time, so that the first locking structures on each frame rod assembly are locked at the same time, and the child's bed is in the unfolded state again.

The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
