[0030] Reference Figs. 1 to 4 When the trolley is unfolded, the bottom frame 1 and the reinforcement rod 2 can be organically formed into an integrated supporting structure through the locking mechanism and the hinge seat 3, thereby improving the structural strength and stability of the one-button folding mechanism of the outdoor stroller.

[0031] As shown in the figure, the locking mechanism includes a connecting rod 5, a locking seat 6 that slides with the reinforcing rod 2, and a card rod 7 arranged on the reinforcing rod 2. The locking seat 6 is provided with a positioning groove 8. One end of the connecting rod 5 is located in the positioning groove 8 and is hinged to the groove wall of the positioning groove 8. The bottom surface of the positioning groove 8 can limit the rotation direction of the connecting rod 5, so that when unfolded, the connecting rod 5 can maintain the tilt angle through the restriction of the positioning groove 8. One end of the connecting rod 5 is hinged to the hinge seat 3, and the locking seat 6 is provided with a rotatable card 9 and an elastic member 10 for resetting the card 9. The card 9 is provided with a card slot 11 that is locked with the card rod 7. The unlocking member 4 is connected to the card 9 by a pull rope and can pull the card 9 to rotate so that the card slot 11 is separated from the card rod 7. When the one-touch folding mechanism of the outdoor stroller is unfolded, the connecting rod 5 is locked with the card rod 7 through the card 9, so that the two connecting rods 5 and the two reinforcing rods 2 form a stable triangular structure, thereby greatly improving the structural stability of the one-touch folding mechanism of the outdoor stroller; when the one-touch folding mechanism of the outdoor stroller needs to be folded, the user pulls the unlocking member 4 through the rope, and the unlocking member 4 pulls the card 9 through the pull rope (not shown in the figure) to rotate the card slot 11 and the card rod 7 so that the locking seat 6 can slide along the reinforcing rod 2. Of course, there is a sliding hole 25 on the locking seat 6 that cooperates with the reinforcing rod 2. The unlocking member 4 continues to drive the hinge seat 3 to be lifted up, and the hinge seat 3 can drive the connecting rod 5 to rotate. At the same time, the hinge seat 3 drives the bottom frame 1 and the reinforcing rod 2 to rotate and close and fold to achieve folding.

The elastic member 10 is a spring and one end of the spring is located in the mounting hole 15 and the other end of the spring is against the end of the support plate 16. Through the above structure, the spring is hidden in the mounting hole 15 and positioned, and can be against the card 9. The rotation of the card 9 is achieved through the above structure and is convenient for assembly and manufacturing.

[0035] As shown in the figure, a seat base plate 17 is provided at the bottom of the hinged seat 3. The end of the reinforcing rod 2 is hinged to the seat base plate 17 and can be against the bottom surface of the hinged seat 3 to limit its rotation. The above structure can limit the rotation of the reinforcing rod 2, so that the reinforcing rod 2 can maintain horizontal support when unfolded.

[0036] As shown in the figure, it also includes a connecting plate 18, an arc guide groove 19 is provided on the hinge seat 3, one end of the connecting plate 18 is fixed to the corresponding bottom frame 1 and the other end of the connecting plate 18 is hinged to the hinge seat 3, the arc guide groove 19 is provided with a guide rod 1 (not shown in the figure) that can slide along the arc guide groove 19, the guide rod 1 is rotatably connected to the connecting plate 18, and also includes a connecting plate 20, a straight guide groove 21 is provided on the hinge seat 3, the straight guide groove 21 is provided with a guide rod 2 (not shown in the figure) that can slide along the straight guide groove 21, the end of the connecting plate 20 is hinged to the connecting plate 18, and the guide rod 2 is rotatably connected to the connecting plate 20, through the coordinated guidance of the arc guide groove 19 and the guide rod 1, and the coordinated guidance of the straight guide groove 21 and the guide rod 2, it can be ensured that the bottom frame 1 is smoother and will not deflect when rotating, and the strength of the overall structure of the bottom frame 1 and the hinge seat 3 is enhanced.

[0037] As shown in the figure, a seat hole 22 is provided on the top surface of the hinge seat 3, and the unlocking member 4 is located in the seat hole 22. Elastic plates 23 are provided on both sides of the unlocking member 4. A limit block 24 is provided on the elastic plate 23. A boss that can be abutted against the limit block 24 is provided on the hole wall of the seat hole 22. The above facilitates the insertion of the unlocking member 4 into the seat hole 22 and moves up and down through the elasticity of the elastic plate 23. After insertion, the unlocking member 4 is ensured not to fall out by the limit block 24 and the boss, which not only ensures that the unlocking member 4 realizes the sliding unlocking function but also facilitates installation.
