[0027] 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.

[0028] See also Figures 1 to 8 The present invention discloses an easily foldable baby stroller, which comprises a handle assembly 10, a seat plate 20, a front armrest 30, a footrest 40, a front leg tube 50, a rear leg tube 60, an armrest connecting tube 70, a rear leg connecting piece 80 and a locking structure 90.

[0029] The handle assembly 10 includes an upper handle tube 11, a lower handle tube 12, and a button 13. The upper handle tube 11 is slidably mounted on the lower handle tube 12. The button 13 is mounted on the upper handle tube 11 to lock the upper handle tube 11. The upper handle tube 11 includes a sliding unlocking member 110, which is located near one end of the lower handle tube 12. The sliding unlocking member 110 is provided with an unlocking inclined surface.

[0030] The seat plate 20 includes a seat locking member 21. The locking structure 90 includes a locking pin 91, a locking hook 92 and an elastic member 93. The locking pin 91 is fixed to the handlebar lower tube 12. The locking hook 92 includes a buckle portion 920, and the buckle portion 920 is provided with an inclined surface. The locking hook 92 is rotatably mounted on the front leg tube 50. One end of the elastic member 93 is connected to the front leg tube 50, and the other end is connected to the locking hook 92. The installation position of the locking hook 92 rotatably mounted on the front leg tube 50 is located between the buckle portion 920 and the connection between the locking hook 92 and the elastic member 93.

[0031] When assembling the foldable baby stroller, the handlebar lower tube 12 of the handlebar assembly 10 is rotatably connected to the front leg tube 50, and the buckle portion 920 of the lock hook 92 is buckled with the lock pin 91, so that the handlebar lower tube 12 is locked with the front leg tube 50. The front armrest 30 is rotatably connected to the front leg tube 50. The seat plate 20 is rotatably connected to the front armrest 30, and the seat locking member 21 extends into the handlebar lower tube 12 and locks with the handlebar lower tube 12. At this time, the front armrest 30 and the handlebar assembly 10 are in a √ shape. The seat plate 20 is located between the front armrest 30 and the handlebar assembly 10 and is parallel to the horizontal plane. The footrest 40 is slidably mounted on the front leg tube 50, and one end of the handrail connecting tube 70 is rotatably connected to the front armrest 30, and the other end is rotatably connected to the footrest 40. The rear leg tube 60 is rotatably connected to the front leg tube 50, and one end of the rear leg connecting member 80 is rotatably connected to the rear leg tube 60, and the other end is rotatably connected to the footrest 40. At this time, the rear leg tube 60 and the front leg tube 50 are in an inverted V shape. The easily foldable baby stroller is in an X shape.

[0032] When the baby stroller needs to be folded, the button 13 is pressed to unlock the handlebar upper tube 11 and the handlebar lower tube 12, and the handlebar upper tube 11 is pushed downward, so that the handlebar upper tube 11 moves downward along the handlebar lower tube 12. During the movement, the sliding unlocking member 110 of the handlebar upper tube 11 hits the seat locking member 21 of the seat plate 20, so that the seat locking member 21 moves laterally and disengages from the handlebar lower tube 12, so that the seat plate 20 is unlocked from the handlebar lower tube 12. The handlebar upper tube 11 continues to move downward until the sliding unlocking member 110 of the handlebar upper tube 11 hits the buckle portion 920 of the lock hook 92, the lock hook 92 rotates counterclockwise, and the buckle portion 920 of the lock hook 92 disengages from the lock pin 91, so that the handle assembly 10 is unlocked from the front leg tube 50. An external force is applied to the handlebar assembly 10, so that the handlebar assembly 10 rotates counterclockwise, and the handlebar assembly 10 drives the seat plate 20 to rotate counterclockwise, until the handlebar assembly 10 overlaps with the front armrest 30. The handle assembly 10 continues to rotate counterclockwise, driving the front armrest 30 to rotate counterclockwise. The footrest 40 slides on the front leg tube 50 due to the action of the armrest connecting tube 70, and the rear leg connecting member 80 moves forward due to the action of the footrest 40 and drives the rear leg tube 60 to fold inward clockwise until all parts are folded and folded.

[0033] The entire folding process is simple to operate and easy to use, and the volume after folding is small, making it easy to store and carry.

[0034] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
