[0028] See Figure 1 and Figure 3 A bed structure includes: a polygonal frame 100, the polygonal frame 100 including at least two parallel telescopic rods 200, the polygonal frame 100 having an extended state and a retracted state as the telescopic rods 200 extend and retract. The polygonal frame 100 can be stretched along the extension direction of the telescopic rods 200 to reach the extended state, or can be retracted along the shortening direction of the telescopic rods 200 to reach the retracted state. The polygonal frame 100 is rotatably connected to the support legs 300 capable of supporting the polygonal frame 100. In the extended state, all the support legs 300 are in contact with the ground to form a stable support structure. The support legs 300 can be rotatably stored inside the polygonal frame 100 in the retracted state. The polygonal frame 100 is detachably mounted with an upward-opening storage basket 600, wherein the storage basket 600 is for children or infants to lie down or stand. When the bed structure of this embodiment is stored, the storage basket is removed from the polygonal frame 100, and then the telescopic rod 200 on the polygonal frame 100 is retracted to shrink the polygonal frame. Each support leg 300 is rotated and stored inside the retracted polygonal frame 100, thereby folding the bed structure into a flat shape, greatly reducing the storage space and making it convenient to carry and transport.

[0029] See Figure 1 and Figure 2In some embodiments of the present invention, the polygonal frame 100 is a rectangular frame, which includes two long rods and two wide rods. The long rods and / or the wide rods are telescopic rods 200, and a support leg 300 is rotatably connected to each of the four corners of the rectangular frame. Preferably, both the long rods and the wide rods are telescopic rods 200. In some embodiments, the telescopic rod 200 includes an inner rod 210 and an outer rod 220 movably fitted outside the inner rod 210. At least two stop holes are distributed at intervals along the length direction on one of the inner rod 210 and the outer rod 220, and a ball bearing structure that can be combined with any of the stop holes is provided on the other of the inner rod 210 and the outer rod 220.

[0030] See Figure 3 and Figure 4 In some embodiments of the present invention, an elastic self-locking mechanism 400 for locking the unfolding angle of the support leg 300 is provided between the support leg 300 and the rectangular frame. The elastic self-locking mechanism 400 can quickly fix the support leg 300 after it is unfolded, and prevent the support leg 300 from being rotated further by external force.

[0031] In some embodiments of the present invention, the elastic self-locking mechanism 400 includes a slider 410 slidably disposed on the support leg 300. The slider 410 is provided with a positioning protrusion 420, and the rectangular frame is provided with a positioning groove 430 corresponding to the positioning protrusion 420. A first elastic member 440 is provided between the support leg 300 and the slider 410 to drive the slider 410 closer to the rectangular frame. When the support leg 300 is unfolded, the first elastic member 440 can drive the positioning protrusion 420 to move into the positioning groove 430, thereby fixing the support leg 300. When it is necessary to fold and store the bed structure of the present invention, the slider 410 is pushed to disengage the positioning protrusion 420 from the positioning groove 430, and then the support leg 300 is rotated into the rectangular frame.

[0032] See Figure 5 In some embodiments of the present invention, a rocker arm 500 is detachably mounted between the two legs 300 located at both ends of the wide rod. The rocker arm 500 has an arc-shaped section that contacts the ground. In this case, the bed structure with the rocker arm 500 can be used as a baby rocker, further expanding the functionality of the bed structure of the present invention.

[0033] See Figure 6In some embodiments of the present invention, the rocker arm 500 is provided with mounting joints 510 connected to both ends of the arc-shaped segment, the mounting joints 510 are provided with upwardly extending insertion posts 520, the bottom surface of the support leg 300 is provided with insertion holes 310 that cooperate with the insertion posts 520, the surface of the insertion posts 520 is provided with a ring of anti-detachment grooves 521, the side wall of the support leg 300 is movably provided with anti-detachment clips 320 that move radially along the insertion holes 310, the anti-detachment clips 320 are provided with through holes 321 for the insertion posts 520 to pass through, and the anti-detachment clips 320 are connected to a second elastic member 330 that drives the inner side wall of the through holes 321 to abut against the side of the anti-detachment grooves 521. When the pin 520 on the rocker arm 500 is inserted into the socket 310, the inner wall of the perforation 321 on the anti-detachment card 320 abuts against the anti-detachment groove 521 under the action of the second elastic member 330 to prevent the rocker arm 500 from falling off; when it is necessary to disassemble the rocker arm 500, force is applied in the direction of deformation of the second elastic member 330 to separate the perforation 321 from the anti-detachment groove 521, and then the pin 520 is pulled out of the socket 310.

[0034] In some embodiments of the present invention, the storage basket 600 is made of a flexible woven material, such as mesh fabric, cotton fabric, etc. The opening edge of the storage basket 600 is connected to the polygonal frame, and the support leg 300 is provided with at least one connecting component 340 capable of straightening the bottom of the storage basket 600. Specifically, one connecting component 340 is provided at the middle and bottom of the support leg 300, and the connecting component 340 includes a connecting seat pivotally connected to the support leg 300 and a connecting strap connecting the connecting seat and the bottom of the storage basket 600. See also Figure 1 All the connecting components 340 located in the middle of the support legs 300 are connected to the four corners of the bottom of the storage basket 600, so that the bed structure can be used as a crib. See Figure 2 All the connecting components 340 located at the bottom of the support legs 300 are connected to the four corners of the bottom of the storage basket 600 so that the bottom of the storage basket 600 can contact the ground, and the child can stand and move around in the storage basket 600. This bed structure can be used as a play bed.
