The inner basket joint 9 houses the basket joint gear 13, the inner basket joint turntable 19, the basket joint gear springs 16, and the folding cable 18. Furthermore, the inner basket joint gear 13, the inner basket joint turntable 19, and the basket joint gear springs 16... 6. The folding pull line 18 is connected to form component one. The headband tube 12 is connected between the two basket joints 9, and the footband tube 11 is connected between the two basket joints 10. The sail frame gear spring 14 and sail frame gear 15 are placed inside the basket joint 10, and the sail frame gear spring 14 and sail frame gear 15 are connected to form component two. Component one and component two are movably connected by rivets with the concentric circles of the basket joints 9 and the basket joints 10. The headband tube 12 is equipped with a plate buckle 17. The plate buckle 17 is provided with a hole for placing the fixing terminal of the folding pull line 18. The basket joint 9 is provided with a limit groove. The limit groove is adapted to the positioning flat iron 8 and plays a role in limiting the left and right swing and the up and down sliding.

[0034] The basket intermediate connecting seat assembly includes a head panel 1 and a foot panel 2. An intermediate connecting plate 3 is positioned between the head panel 1 and the foot panel 2. The contact surface between the intermediate connecting plate 3 and the head panel 1 and foot panel 2 bears the weight from the head panel 1 and foot panel 2. Intermediate connecting seats 4 are fixedly connected to the top left and right sides of the intermediate connecting plate 3. The head panel 1 is riveted to a head panel flat iron 5 on each side, and the foot panel 2 is riveted to a foot panel flat iron 6 on each side. The intermediate connecting seat 4 is movably connected to the head panel flat iron 5 and foot panel flat iron 6 on the same side. A connecting flat iron 7 is movably connected between 5 and the foot flat iron 6. A positioning flat iron 8 is fixedly connected to the middle connecting seat 4 by rivets. The middle connecting plate 3, the middle connecting seat 4 and the positioning flat iron 8 are fixed as a whole by rivets. It is a stationary assembly and is stationary when the basket is folded and opened. When opening and closing, the basket joint slides up and down 140mm along the upper limit groove of the positioning flat iron 8. The positioning flat iron 8 has a long groove. The rivets that connect the inner 9 and outer 10 of the basket joint are set through the long groove.

[0035] The left and right middle connecting seats 4 are respectively provided with two arc-shaped limiting grooves for the head and one arc-shaped limiting groove for the feet. The six arc-shaped limiting grooves on the left and right middle connecting seats 4 restrict the basket from continuing to open and keep it in a horizontal state when the basket is open. When the basket is rotated 88 degrees in the middle and fully closed, the basket is restricted from moving and is in a closed state. The six arc-shaped limiting grooves also bear the weight of the baby from the head panel 1 and foot panel 2 when the basket is open.

[0036] The connecting rod section includes two head connecting rods A20, two head connecting rods B21, and two foot connecting rods 22. Two head connecting rods A20 and two head connecting rods B21 are movably connected between the head surround plate 1 and the head surround tube 12. The six connecting rods are arranged in a left-right configuration of three rods each. Adjacent head connecting rods A20 and B21 are arranged parallel to each other. The two foot connecting rods 22 are movably connected between the foot surround plate 2 and the foot surround tube 11. The connecting rod section serves to support and connect the basket joint and the middle connecting seat assembly when the basket is opened and closed. (Head connecting rod B21...) The angle between the head tube 12 and the foot connecting rod 22 and the foot tube 11 is equal to 64 degrees, and the angle range is between +8 degrees and -4 degrees. The angle between the head connecting rod B21 and the head plate 1 and the angle between the foot connecting rod 22 and the foot plate 12 are equal to 116 degrees, and the angle range is between +4 degrees and -9 degrees. When the basket is closed and opened, the head tube 12 and the head plate 1 and the foot tube 11 and the foot plate 2 work together synchronously. When the basket is closed and opened, the head connecting rod A20 and the head connecting rod B21 are always at a parallel angle.

[0037] When the baby carrier is used with a stroller, it can be folded and unfolded together with the stroller without being disassembled.

[0038] The implementation principle of the non-disassembly foldable and openable basket and frame structure in this application embodiment is as follows: When the basket is folded, the buckle 17 is turned clockwise, which in turn rotates the inner turntable 19 of the basket joint by the linkage folding cable 18. The helical teeth of the inner turntable 19 of the basket joint push the helical teeth of the basket joint gear 13 to compress the spring 16 of the basket joint gear and move it into the inner 9 of the basket joint until the outer 10 of the basket joint is dislocated. At the same time, the horizontal position locking state with the inner 9 of the basket joint is released. Then, the headband tube 12 is lifted. The headband tube 12, in conjunction with the head connecting rod A20 and the head connecting rod B21, drives the headband plate 1. The headband plate 1 and the headband flat iron 5 are fixed together by rivets. At the same time, the headband tube 12 continues to be lifted upward, causing the headband flat iron 5 to push the connecting flat iron 7. The connecting flat iron 7 pushes the foot flat iron 6. 6 is fixed to the foot panel 2 by rivets. The foot connecting rod 22 pushes the foot tube 11 to rotate and retract. When the head tube 12 and foot tube 11 rotate towards the middle, since the head tube 12 and the basket joint 9 are fixed to each other by rivets, the limiting groove of the basket joint 9 cooperates with the positioning flat iron 8. At this time, the retraction will be transformed into a rotational retraction movement with the basket joint 9 as the center. At the same time, it slides down along the positioning flat iron 8 to shorten the rotation center distance between the basket joint and the basket middle connecting seat assembly. Until the head tube 12 and foot tube 11 rotate 88 degrees towards the middle, they stop moving due to the rotation limiting groove of the middle connecting seat 4 and are in a retracted state. The basket is in a fully retracted state. The rotation center distance of the basket middle connecting seat assembly part decreases from 220mm to 80mm. The total height after retraction is 570mm.

[0039] The operation of opening the basket is the reverse of the operation of closing it. A counterclockwise force is applied to the head circumference tube 12. The force of the basket joint gear 13, which was pushed by the inner turntable 19 of the basket joint, is released and changed to the elastic force of the spring 16 of the basket joint gear, moving towards the outer 10 of the basket joint until the basket is unfolded into a horizontal state. The two sets of gears of the basket joint gear 13 mesh with the corresponding gears in the inner 9 and outer 10 of the basket joint, respectively. The basket is then locked back into the horizontal unfolded state. When the basket is unfolded into a horizontal state, the maximum outer width is 825mm and the rotation center distance of the middle connecting seat assembly parts of the basket is 220mm.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
