[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0039] See also Figures 1 to 19 , a foldable multifunctional baby chair of the present invention includes a backrest assembly 10, a dining table 20, a connecting joint 30, a seat tube 40, a support assembly 50 and a leg tube assembly 60.

[0040] The backrest assembly 10 includes a backrest tube 11, an armrest 12, a stopper 13, a locking tongue 14, an elastic member 15 and a traction rope. The backrest tube 11 is a hollow structure and is U-shaped as a whole. The armrest 12 is provided with a protrusion 120 or a slot 21. When the armrest 12 is provided with a protrusion 120, the dining table 20 is provided with a slot 21. When the armrest 12 is provided with a slot 21, the dining table 20 is provided with a protrusion 120. The protrusion 120 and the slot 21 are buckled so that the dining table 20 can be detachably mounted on the armrest 12. The armrest 12 is rotatably mounted on the backrest tube 11. The stopper 13 is fixed to the end of the backrest tube 11. The locking tongue 14 is slidably mounted inside the tube body at the end of the backrest tube 11. The elastic member 15 is a spring. The elastic member 15 is installed inside the locking tongue 14 and one end of the elastic member 15 contacts the locking tongue 14, and the other end contacts the backrest tube 11. The traction rope is built into the backrest tube 11 , one end of the traction rope is fixed to the locking tongue 14 , and the other end is fixed to an operating member slidably installed outside the backrest tube 11 .

[0041] The dining table 20 is provided with a protrusion 120 or a slot 21 .

[0042] The connection joint 30 is provided with a plug hole 31, a mounting hole 32, a mounting portion 33, a locking groove 34 and a receiving portion 35. The axis of the plug hole 31 and the axis of the mounting hole 32 are parallel to each other. The receiving portion 35 is located on the inner wall of the connection joint 30, and the receiving portion 35 is connected with the mounting portion 33 and the mounting hole 32. The locking groove 34 is located at the bottom of the mounting portion 33, and the number of the locking grooves 34 is multiple, so as to facilitate the adjustment of the angle of the backrest assembly 10 relative to the seat tube 40.

[0043] The seat tube 40 is generally U-shaped.

[0044] The support assembly 50 includes a support tube 51 and a first torsion spring 52. The support tube 51 is generally V-shaped. A section of the end of the support tube 51 is bent in a V-shape. The first torsion spring 52 is sleeved on the end of the support tube 51.

[0045] The leg tube assembly 60 includes a front leg tube 61, a rear leg tube 62, a rotating shaft 63 and a second torsion spring 64. The rear leg tube 62 is rotatably mounted on the front leg tube 61 via the rotating shaft 63. The second torsion spring 64 is sleeved on the rotating shaft 63 and its two ends are respectively in contact with the front leg tube 61 and the rear leg tube 62.

[0046] When assembling the foldable multifunctional baby chair, the dining table 20 is detachably mounted on the armrest 12 of the backrest assembly 10 through the snap-fit ​​of the slot 21 and the protrusion 120 of the armrest 12. The backrest tube 11 is rotatably mounted on the connecting joint 30. The locking tongue 14 is located in the locking groove 34 to lock the backrest tube 11 with the connecting joint 30. The end of the seat tube 40 is mounted on the plug hole 31 and fixed to the connecting joint 30 by screws. The end of the support tube 51 extends into the mounting hole 32 and is accommodated in the accommodating portion 35. One end of the first torsion spring 52 is fixed to the support tube 51, and the other end is fixed to the connecting joint 30. The end of the support tube 51 is abutted by the limit block 13 to prevent the support tube 51 from rotating relative to the connecting joint 30 under the action of the first torsion spring 52. The other end of the support tube 51 is accommodated in the front leg tube 61 of the leg tube assembly 60 and the front leg tube 61 can rotate relative to the support tube 51. The rear leg tube 62 rotates relative to the front leg tube 61 , so that the rear leg tube 62 and the front leg tube 61 are folded, and the rear leg tube 62 is located below the front leg tube 61 .

[0047] When using the foldable multifunctional baby chair, when the baby chair is used as a dining chair, the dining table 20 is installed on the armrest 12; when the baby chair is used as a seat, the dining table 20 is removed from the armrest 12, the baby chair is lifted, the leg tube assembly 60 leaves the ground, and the rear leg tube 62 rotates relative to the front leg tube 61 under the action of the second torsion spring 64 to achieve automatic opening; when the baby chair is used as a reclining chair, the operating member drives the traction rope so that the traction rope drives the locking tongue 14 to slide relative to the backrest tube 11 and disengage from the locking groove 34, at which time the elastic member 15 is compressed, and the backrest tube 11 is unlocked from the connecting joint 30. The backrest tube 11 rotates relative to the connecting joint 30, the traction rope is released, and the locking tongue 14 extends into another locking groove 34 under the elastic force of the elastic member 15, so that the backrest tube 11 is locked with the connecting joint 30. At this time, the backrest tube 11 tilts backward relative to the seat tube 40, and the baby chair is converted into a reclining chair. Since there are multiple locking grooves 34, when the locking tongue 14 is located in different locking grooves 34, the angle between the backrest tube 11 and the seat tube 40 is different, so that the baby chair can have different gears after being converted into a recliner (i.e., different gears have different backward tilt angles of the backrest tube 11).

[0048] When the multifunctional baby chair needs to be folded, the armrest 12 rotates relative to the backrest tube 11, the operating member drives the traction rope so that the traction rope drives the locking tongue 14 to slide relative to the backrest tube 11 and disengage the locking groove 34, and the backrest tube 11 rotates forward relative to the connecting joint 30 to complete the folding. At this time, the backrest tube 11 drives the limit block 13 to move, and the limit block 13 is separated from the end of the support tube 51. The end of the support tube 51 rotates relative to the connecting joint 30 under the action of the first torsion spring 52 to complete the folding, and the end of the support tube 51 rotates from the receiving portion 35 to the mounting portion 33. The leg tube assembly 60 rotates relative to the support tube 51. The rear leg tube 62 folds relative to the front leg tube 61. At this time, the multifunctional baby chair is completely folded.

[0049] Through the above design, the baby chair can be used as a dining chair when the dining table 20 is installed on the armrest 12, and the baby chair can be used as a seat after the dining table 20 is disassembled. The baby chair can be used as a reclining chair after the backrest assembly 10 is rotated relative to the connecting joint 30, thereby realizing multiple uses of one chair; the backrest assembly 10 and the support tube 51 can both rotate relative to the connecting joint 30, and the support tube 51 and the leg tube assembly 60 are also rotatably connected, so that the baby chair can be folded for easy carrying and storage.

[0050] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of them belong to the protection scope of the present invention.
