[0054] The frame assembly is widely used in rocking beds and folding beds. The frame assembly is usually formed of a ring-shaped body surrounded by multiple surrounding rods, and a cloth cover is placed on the ring-shaped body. The cloth cover is surrounded at the bottom and around to form a space for lying and sleeping. Due to the surrounding of the cloth cover, when observing the child lying and sleeping inside, it is necessary to observe from the top, which is very inconvenient.

[0055] In the related art, a foldable side frame is provided on one side of the main frame in the frame assembly to convert the rocking bed into a bedside bed, and springs and sleeves are used at both ends of the side frame to limit the degree of freedom of the rotating joint, resulting in a complex structure and cumbersome operation.

[0056] Based on the above problems, the present invention proposes a surrounding frame assembly, aiming to provide a surrounding frame assembly with simple structure and easy operation.

[0057] See also Figures 1 to 4 In one embodiment of the present invention, the frame assembly 100 includes:

[0058] The first enclosure frame 10 has a pair of main enclosure bars 11 and a main connecting enclosure bar 12 connected between the pair of main enclosure bars 11;

[0059] The second enclosure 20 includes a pair of connecting enclosure rods 30 and a telescopic enclosure rod 40 disposed between the pair of connecting enclosure rods 30; the pair of connecting enclosure rods 30 are rotatably connected to the pair of main enclosure rods 11 respectively, and the connecting enclosure rods 30 are rotatably connected to the main enclosure rods 11 along the first axis a direction; the telescopic enclosure rod 40 is rotatably connected to the connecting enclosure rod 30 along the first rotation axis 50a, and the first rotation axis 50a is extended in a direction perpendicular to the telescopic enclosure rod 40;

[0060] The first rotating shaft 50a is movable between a first position and a second position. In the first position, the extending direction of the first rotating shaft 50a is parallel to the extending direction of the first axis a, and the connecting enclosure rod 30 can rotate relative to the main enclosure rod 11 and stretch the telescopic enclosure rod 40.

[0061] The technical solution of the present invention is to make a pair of connecting enclosures 30 rotatably connected to a pair of main enclosures 11 respectively, and make the connecting enclosures 30 rotatably connected to the main enclosures 11 along the direction of the first axis a, and the telescopic enclosure 40 is rotatably connected to the connecting enclosure 30 along the first rotation axis 50a, and the first rotation axis 50a is extended in a direction perpendicular to the telescopic enclosure 40, so that the first rotation axis 50a can move between a first position and a second position; wherein, in the first position, the extension direction of the first rotation axis 50a is parallel to the extension direction of the first axis a, so that the frame assembly 100 is in an unlocked state, at this time, the connecting enclosure 30 can rotate relative to the main enclosure 11 and stretch the telescopic enclosure 40; and in the second position, the extension direction of the first rotation axis 50a forms an angle with the extension direction of the first axis a, so that the frame assembly 100 is in a locked state, at this time, the connecting enclosure 30 cannot rotate relative to the main enclosure 11.

[0062] Therefore, during use, by changing the position of the first rotating shaft 50a so that the first rotating shaft 50a moves to the first position, the frame assembly 100 can be in an unlocked state, and the rocking bed can be smoothly converted into a bedside bed; and by changing the position of the first rotating shaft 50a so that the first rotating shaft 50a moves to the second position, the frame assembly 100 can be in a locked state to limit the freedom of the rotating joint, replacing the use of springs and sliding sleeves at both ends of the side frames to limit the freedom of the rotating joint, the structure is relatively simple, and the operation is easier.

[0063] As some examples, the first enclosure frame 10 may be a U-shaped tubular structure, wherein the middle tube section of the U-shaped tubular structure is a main connecting enclosure rod 12 , and the tube sections on both sides of the U-shaped tubular structure are a pair of main enclosure rods 11 .

[0064] As some examples, the connecting rod 30 may be an L-shaped tubular structure, one end of which is rotatably connected to the main rod 11, and the other end of which is rotatably connected to one end of the telescopic rod 40. Of course, in other embodiments, the connecting rod 30 may also be a straight tubular structure, an arc-shaped tubular structure, or the like.

[0065] In actual application, the first rotating shaft 50 a can be directly installed on the telescopic enclosure rod 40 , or can be installed on the connecting component 50 between the telescopic enclosure rod 40 and the main enclosure rod 11 .

[0066] Optionally, in one embodiment of the present invention, the first rotating shaft 50a is disposed on the telescopic enclosure rod 40, and when the telescopic enclosure rod 40 rotates around its axis c, the first rotating shaft 50a switches between the first position and the second position.

[0067] In this arrangement, by directly installing the first rotating shaft 50a on the telescopic enclosure rod 40, when the telescopic enclosure rod 40 is rotated to rotate the telescopic enclosure rod 40 around its axis c, the first rotating shaft 50a can be switched between the first position and the second position, so that the enclosure frame assembly 100 can be smoothly switched between the locked state and the unlocked state.

[0068] Optionally, see Figures 1 to 4 In another embodiment of the present invention, the frame assembly 100 further includes a connecting assembly 50 having a first rotating shaft 50a, and both ends of the connecting assembly 50 where the first rotating shaft 50a is located are rotatably connected to the telescopic enclosure rod and the connecting enclosure rod respectively.

[0069] In this way, by setting the first rotating shaft 50a on the connecting component 50, the connecting component 50 is used to realize the rotational connection between the telescopic enclosure 40 and the connecting enclosure 30. In this way, it is only necessary to control the rotation of the connecting component 50 to realize the switching of the first rotating shaft 50a between the first position and the second position, which is more convenient to operate.

[0070] As some examples, the two connecting components 50 have the same structure, so that when the telescopic enclosure rod 40 rotates around its axis c, the two connecting components 50 can be synchronously switched between the first position and the second position, so that the frame assembly 100 can be smoothly switched between the locked state and the unlocked state.

[0071] It should be noted that, in the second position, the connecting rod 30 forms an angle along the first axis a with the axis b of the connecting rod 30 rotating relative to the telescopic rod 40, that is, at this time, the first axis a forms an angle with the extension direction of the first rotating shaft 50a. Since the first axis a and the axis b are not parallel, a mutual restriction is formed, which can limit the degree of freedom of the rotating joint, so that the frame assembly 100 is in a locked state.

[0072] In the first position, the connecting rod 30 is parallel to the axis line b of the connecting rod 30 rotating relative to the telescopic rod 40 along the first axis a, that is, at this time, the first axis a is parallel to the extension direction of the first rotating shaft 50a. Since the first axis a is parallel to the axis line b, the freedom of the rotating joint is no longer restricted, so that the frame assembly 100 is in an unlocked state.

[0073] See also Figures 5 to 9In one embodiment of the present invention, the connecting assembly 50 includes a fixed connecting member 51 and a rotatable joint 52; the fixed connecting member 51 is connected to the connecting enclosure 30; the rotatable joint 52 is rotatably connected to the fixed connecting member 51 and rotates around the axis of the telescopic enclosure 40, one end of the telescopic enclosure 40 is rotatably connected to the rotatable joint 52 through a first rotating shaft 50a, and the axis d about which the rotatable joint 52 rotates relative to the fixed connecting member 51 forms an angle with the axis b about which the telescopic enclosure 40 rotates relative to the rotatable joint 52.

[0074] With such arrangement, the rotatable joints 52 of the two connecting components 50 can be first rotatably connected to the corresponding fixed connecting parts 51, and then the fixed connecting parts 51 of the two connecting components 50 can be respectively connected to the two connecting enclosures 30, and the two ends of the telescopic enclosure 40 can be rotatably connected to the rotatable joints 52 of the two connecting components 50 through the first rotating shaft 50a, so that the two ends of the telescopic enclosure 40 are rotatably connected to the two connecting enclosures 30 through the two connecting components 50, and under the rotational connection between the rotatable joints 52 and the fixed connecting parts 51, the telescopic enclosure 40 can be smoothly rotated along its axis c.

[0075] It should be noted that the axis line b about which the telescopic enclosure rod 40 rotates relative to the rotatable joint 52 is the axis line b about which the connecting enclosure rod 30 rotates relative to both ends of the telescopic enclosure rod 40 .

[0076] As some exemplary embodiments, screws or pins may be used to connect the fixed connecting members 51 of the two connecting assemblies 50 to the two connecting fence rods 30 .

[0077] See also Figure 8 , Fig. 9 In one embodiment of the present invention, a rotation groove 511 is provided at one end of the fixed connection member 51, and a rotation head 521 is provided at one end of the rotatable joint 52, and the rotation head 521 is rotatably matched with the rotation groove 511.

[0078] With such arrangement, the rotational connection between the rotatable joint 52 and the fixed connection member 51 can be more reliably achieved through the cooperation between the rotation head 521 and the rotation groove 511 .

[0079] See also Figure 8 , Fig. 9 In one embodiment of the present invention, a rotation limiting portion 5211 is provided at the end of the rotating head 521 , a limiting step 5111 is provided at the groove wall of the rotating groove 511 , and the rotation limiting portion 5211 abuts against the limiting step 5111 .

[0080] With such arrangement, when the rotating head 521 is installed in the rotating groove 511 , the rotating limit portion 5211 will abut against the limit step 5111 to prevent the rotating head 521 from escaping from the rotating groove 511 during use, thereby affecting the reliability of the rotating connection between the rotating head 521 and the rotating groove 511 .

[0081] See also Figure 8 , Fig. 9 In one embodiment of the present invention, the groove wall of the rotating groove 511 is further provided with an installation opening 5112 penetrating to the outer wall of the fixed connecting member 51 , and the rotating head 521 is installed into the rotating groove 511 through the installation opening 5112 .

[0082] With such arrangement, during the disassembly and assembly process, the rotating head 521 can be smoothly installed into the rotating groove 511 from the installation opening 5112 , or the rotating head 521 can be smoothly removed from the installation opening 5112 , so as to realize convenient disassembly and assembly of the rotating head 521 .

[0083] See also Figures 6 to 9 In one embodiment of the present invention, one end of the fixed connecting member 51 and the rotatable joint 52 are inserted into the connecting rod 30.

[0084] Such a configuration can improve the installation reliability between the connecting component 50 and the connecting fence 30, and at the same time, the installation opening 5112 on the fixed connecting member 51 can be blocked to prevent the rotating head 521 from escaping from the installation opening 5112 during use, thereby affecting the reliability of the rotational connection between the rotating head 521 and the rotating groove 511.

[0085] As some exemplary embodiments, the rotatable joint 52 includes a first rotating end and a second rotating end connected to each other, a rotating head 521 is connected to the end of the first rotating end away from the second rotating end, the first rotating ends of the two connecting components 50 are respectively inserted into the two connecting rods 30, and the second rotating ends of the two connecting components 50 are respectively rotatably connected to the two ends of the telescopic rod 40.

[0086] See also Figure 7 , Fig.10 In one embodiment of the present invention, the rotatable joint 52 of at least one connecting component 50 and one of the connecting surrounding rods 30 connected thereto are provided with a first limiting member, and the other one thereof is provided with a first limiting groove 31, and the first limiting member cooperates with the first limiting groove 31 to limit the rotation angle of the telescopic surrounding rod 40 around its axis c.

[0087] With such a configuration, the first limiting member and the first limiting groove 31 can cooperate to limit the rotation angle of the telescopic enclosure 40 around its axis c, so that the telescopic enclosure 40 can drive the connecting component 50 to switch between the first position and the second position, and can accurately stay in the first position or the second position.

[0088] In one embodiment, a first limiting member may be provided on the rotatable joint 52 of one of the connecting components 50, and a first limiting groove 31 may be provided on the connecting fence 30 connected thereto; or, a first limiting member may be provided on the rotatable joint 52 of another connecting component 50, and a first limiting groove 31 may be provided on the connecting fence 30 connected thereto.

[0089] In another embodiment, a first limiting member may be provided on the rotatable joints 52 of the two connecting assemblies 50 , and a first limiting groove 31 may be provided on the two connecting surrounding rods 30 .

[0090] In some embodiments, the first limiting member may be a spring pin, and the first limiting groove 31 may be an arc-shaped groove.

[0091] See also Figure 7 In one embodiment of the present invention, both ends of the telescopic fence rod 40 are provided with joint heads 41, and each joint head 41 is rotatably connected to a connecting component 50 through a first rotating shaft 50a.

[0092] With such arrangement, the joint heads 41 at both ends of the telescopic fence rod 40 are rotatably connected to the two connecting assemblies 50 respectively through the first rotating shaft 50a, so that the rotatable connection between the two ends of the telescopic fence rod 40 and the two connecting fence rods 30 through the connecting assemblies 50 is more reliable.

[0093] See also Figure 7 In one embodiment of the present invention, one end of each joint head 41 is rotatably connected to a connecting component 50 via a first rotating shaft 50a, and the other end of each joint head 41 is inserted into one end of the telescopic enclosure rod 40; in this way, the connection reliability between the joint head 41 and the telescopic enclosure rod 40 can be improved.

[0094] As some exemplary embodiments, the joint head 41 may be connected to the telescopic fence 40 using screws or pins.

[0095] See also Figure 6 , Figure 7 , Fig.11 , Fig.12 In one embodiment of the present invention, the telescopic enclosure rod 40 includes a telescopic rod 42 and a telescopic sleeve 43; one end of the telescopic rod 42 is rotatably connected to a connecting enclosure rod 30 through a connecting assembly 50; one end of the telescopic sleeve 43 is rotatably connected to another connecting enclosure rod 30 through another connecting assembly 50, the telescopic sleeve 43 is sleeved on the telescopic rod 42, and slides relative to the telescopic rod 42 along its axial direction to extend or shorten the telescopic enclosure rod 40, and the telescopic sleeve 43 drives the telescopic rod 42 to rotate through the positioning structure.

[0096] With such arrangement, the telescopic rod 42 and the telescopic sleeve 43 can be slidably cooperated with each other, so that the telescopic enclosure rod 40 can be extended or shortened more smoothly. In addition, under the action of the positioning structure, the telescopic sleeve 43 can drive the telescopic rod 42 and the associated joint head 41 to rotate when the telescopic sleeve 43 rotates around its axis, thereby avoiding relative rotation between the telescopic rod 42 and the telescopic sleeve 43 and affecting the locking and unlocking effect of the enclosure frame assembly 100.

[0097] See also Figure 7 In one embodiment of the present invention, the positioning structure includes a slide groove 421 and a positioning pin 431. The slide groove 421 is extended along the axial direction of the telescopic rod 42. One of the telescopic rod 42 and the telescopic sleeve 43 is provided with a slide groove 421, and the other one is provided with a positioning pin 431. The positioning pin 431 is slidably matched with the slide groove 421.

[0098] With such arrangement, during the installation process, the telescopic rod 42 can be smoothly inserted into the telescopic sleeve 43 after the slide groove 421 is aligned with the positioning pin 431, which not only prevents the telescopic rod 42 and the telescopic sleeve 43 from rotating relative to each other, but also guides the relative sliding between the telescopic rod 42 and the telescopic sleeve 43 under the cooperation of the slide groove 421 and the positioning pin 431, so as to improve the stability of the telescopic enclosure rod 40 during the extension or shortening process.

[0099] As some examples, the slide groove 421 can also be a limit groove, so as to limit the sliding distance between the telescopic rod 42 and the telescopic sleeve 43 under the cooperation of the limit groove and the positioning pin 431, so as to limit the extension or shortening distance of the telescopic enclosure rod 40.

[0100] See also Figure 6 , Figure 7 In one embodiment of the present invention, the axis a of the connecting rod 30 rotating relative to the main rod 11 coincides with the axis of one end of the connecting rod 30 itself.

[0101] Such arrangement allows one end of a pair of connecting rods 30 to rotate around their own axis relative to a pair of main rods 11, making the rotation connection of one end of a pair of connecting rods 30 relative to a pair of main rods 11 more reliable.

[0108] See also Fig.12 In the second position, the first surrounding frame 10 and the second surrounding frame 20 form a frame body, and the frame body has an upper opening opening upward and a side opening opening laterally;

[0109] In the first position, the height of the telescopic enclosure rod 40 is the same as the height of the main enclosure rod 11 ; in the second position, the height of the telescopic enclosure rod 40 is lower than the height of the main enclosure rod 11 .

[0110] With such arrangement, when in the first position, the first surrounding frame 10 and the second surrounding frame 20 together form a frame body opening upward, and at this time, the children's bed using the frame body can be used as a rocking bed; and when in the second position, the first surrounding frame 10 and the second surrounding frame 20 form a frame body having an upper opening opening upward and a side opening opening sideways, and at this time, the children's bed using the frame body can be used as a bedside bed.

[0111] It should be noted that the frame assembly 100 has a first state and a second state. When the frame assembly 100 is in the first state, the first frame 10 and the second frame 20 are located on the same plane. At this time, the telescopic rod 40 can be rotated so that the telescopic rod 40 rotates around its axis c until the connecting assembly 50 is in the second position to lock the frame assembly 100 in the first state; when the frame assembly 100 is in the second state, the telescopic rod 40 is located below one side of the plane where the first frame 10 is located. At this time, the rocking bed can be converted into a bedside bed.

[0112] See also Figure 5 , Fig.11, Fig.12 In one embodiment of the present invention, when the enclosure assembly 100 switches from the first state to the second state, one end of one of the connecting enclosure rods 30 rotates clockwise relative to the main enclosure rod 11 connected thereto, and one end of the other connecting enclosure rod 30 rotates counterclockwise relative to the main enclosure rod 11 connected thereto, and the other ends of the two connecting enclosure rods 30 rotate relative to the two ends of the telescopic enclosure rod 40 respectively, and the telescopic enclosure rod 40 extends and moves to a side lower than the first enclosure frame 10, so as to convert the rocking bed into a bedside bed;

[0113] When the enclosure assembly 100 switches from the second state to the first state, one end of one of the connecting enclosure rods 30 rotates counterclockwise relative to the main enclosure rod 11 connected thereto, and one end of the other connecting enclosure rod 30 rotates clockwise relative to the main enclosure rod 11 connected thereto, and the other ends of the two connecting enclosure rods 30 rotate relative to the two ends of the telescopic enclosure rod 40 respectively, and the telescopic enclosure rod 40 shortens and moves toward the plane where the first enclosure frame 10 is located, so as to convert the bedside bed into a rocking bed.

[0114] In this embodiment, the frame assembly 100 can switch from the first state to the second state in the following two ways:

[0115] Method 1: bend the two connecting rods 30, one of the connecting rods 30 rotates clockwise, and drives the telescopic sleeve 43 to move to the lower left through the connecting component 50 and the joint head 41 connected thereto, and at the same time, the other connecting rod 30 rotates counterclockwise, and drives the telescopic rod 42 to move to the lower right through the connecting component 50 and the joint head 41 connected thereto, and at the same time, the telescopic rod 42 and the telescopic sleeve 43 move to the left and right ends respectively, until the two connecting rods 30 rotate to the position where the second limiting piece and the second limiting groove 13 are limited.

[0116] Method 2: Press the telescopic sleeve 43 downward, and drive one of the connecting rods 30 to rotate counterclockwise through the connecting assembly 50 and the joint head 41 connected thereto, and at the same time, the telescopic sleeve 43 moves to the lower right. At the same time, the telescopic rod 42 moves in the telescopic sleeve 43, and the joint head 41 and the connecting assembly 50 move with the telescopic rod 42, driving the other connecting rod to rotate clockwise until the two connecting rods 30 rotate to the position where the second limiting piece and the second limiting groove 13 are limited.

[0117] It should be noted that the process of converting from the second state to the first state is opposite to the process of converting from the first state to the second state, and will not be described in detail here.

[0118] See also Fig.11 , Fig.12The present invention also provides a child bed 1000, which includes a base frame 200 and a surrounding frame assembly 100.
