[0029] The present utility model will be further described below with reference to the accompanying drawings:

[0030] As Figures 1 to 9 shown, a baby stroller includes front legs 11, the lower ends of the front legs 11 are connected with front wheels 1a, the upper ends of the front legs 11 are connected with a front connecting seat 12, a rear connecting seat 22 is rotatably connected to the front connecting seat 12 about a first axis A, a rear leg 21 is connected to the rear connecting seat 22, the lower end of the rear leg 21 is connected with a rear wheel 2a, a push rod seat 3 is also rotatably connected to the rear connecting seat 22 about the first axis A, a push rod assembly 4 for pushing is connected to the push rod seat 3, and the push rod assembly 4 includes a lower push rod 41 fixed to the push rod seat 3, and an upper push rod 42 capable of sliding and telescoping therein is arranged in the lower push rod 41.

[0031] As Figures 1 to 9 shown, the baby stroller further includes a seat support seat 6 hinged to the front connecting seat 12 about a third axis C at the rear side and capable of rotating relative to the front connecting seat 12, and a seat assembly 8 is also connected to the seat support seat 6.

[0032] As Figures 1 to 9As shown, when the stroller is folded, the push rod assembly 4 rotates backward and closes to the rear legs 21, the front legs 11 also rotate and close to the rear legs 12, and the seat support base 6 drives the seat assembly 8 to rotate and close to the front legs 11. In this embodiment, the seat assembly 8 includes a seat board 81 connected to the seat support base 6, and a backrest 82 and armrests 83 that can rotate relative to the seat board 81 to be unfolded or folded. When the stroller is folded, the backrest 82 and armrests 83 are first rotated and closed to the seat board 81. The folding structure between the backrest 82 and armrests 83 and the seat board 81 can adopt a traditional folding mechanism, which will not be elaborated here.

[0033] As Figures 1 to 9 shown, in order to make the folding of the stroller flexible, a transmission component is provided among the push rod seat 3, the rear connecting seat 22 and the front connecting seat 12. The transmission component includes a first transmission piece 51 rotatably connected to the rear connecting seat 22 around the second axis B. A strip-shaped groove 52 is provided on the push rod seat 3. A transmission pin 53 is provided on the first transmission piece 51 and penetrates into the strip-shaped groove 52 and can cooperate with the groove wall of the strip-shaped groove 52 when the push rod seat 3 rotates around the first axis A to make the first transmission piece 51 rotate around the second axis B. A second transmission piece 54 is hinged between the middle of the first transmission piece 51 and the front connecting seat 12 and can pull the front connecting seat 12 to rotate and close relative to the rear connecting seat 22 when the first transmission piece 51 rotates around the second axis B. When the push rod assembly 4 rotates backward, the push rod seat 3 rotates around the first axis A relative to the rear connecting seat 22. During the rotation process, the groove wall of the strip-shaped groove 52 on the push rod seat 3 pushes the transmission pin 53, thereby pushing the first transmission piece 51 to rotate around the second axis B relative to the rear connecting seat 22. The first transmission piece 51 pulls the second transmission piece 54 during the rotation process. The second transmission piece 54 rotates relative to the first transmission piece 51 and the front connecting seat 12, and the second transmission piece 54 pulls the front connecting seat 12 to rotate and close relative to the rear connecting seat 22 around the first axis A, so that the front legs 11 rotate and close to the rear legs 21, thus realizing that both the push rod assembly 4 and the front legs 11 close to the rear legs 21, and the folding action is flexible and convenient.

[0034] As Figures 1 to 9As shown in the figure, in order to make the seat support base 6 and the seat assembly 8 approach the front leg 11 during the process of the push rod assembly 4 and the front leg 11 approaching the rear leg 21, a traction assembly 7 is provided between the seat support base 6 and the push rod base 3. When the push rod base 3 rotates and folds relative to the rear connection base 22, the traction assembly 7 can pull the seat support base 6 towards the front leg 11. The traction assembly 7 includes a first traction piece 71 and a second traction piece 72. The upper end of the first traction piece 71 is hinged to the front side of the seat support base 6 around the fourth axis D. The lower end of the second traction piece 72 is hinged to the front leg 11 or the front connection base 12 around the fifth axis E. The lower end of the first traction piece 71 and the upper end of the second traction piece 72 are hinged around the sixth axis F. The traction assembly 7 further includes a third traction piece 73. The front end of the third traction piece 73 is hinged to the first traction piece 71 and the second traction piece 72 around the sixth axis F. The rear end of the third traction piece 73 is provided with a protruding convex shaft 74. The push rod base 3 is provided with a first arc-shaped groove 75 for the convex shaft 74 to penetrate along the circumferential direction. The first arc-shaped groove 75 has a first end 751 and a second end 752. During the process of the push rod base 3 rotating and approaching the rear connection base 22, the first end 751 pushes the convex shaft 74, so that the third traction piece 73 pulls the first traction piece 71 and the second traction piece 72 to move. Therefore, during the process of the push rod assembly 4 rotating backward, when the push rod assembly 4 rotates to a certain angle, the first end 751 of the first arc-shaped groove 75 pushes the convex shaft 74, so that the third traction piece 73 moves backward. The third traction piece 73 then pulls backward the connection position of the first traction piece 71 and the second traction piece 72, so that the first traction piece 71 and the second traction piece 72 rotate relative to the seat support base 6 and the front leg 11 or the front connection base 12 respectively, so that the seat support base 6 drives the seat assembly 8 to rotate relative to the front connection base 12 and approach the front leg 11. The whole traction assembly 7 is simple and compact, and the movement is stable and reliable. During the process of the push rod assembly 4 rotating and folding, the seat assembly 8 is driven to fold, making the folding operation of the baby stroller convenient and fast.

[0035] As Figures 5 to 10 shown, the front connection base 12 is provided with a second arc-shaped groove 76 for the convex shaft 74 to penetrate along the circumferential direction. The second arc-shaped groove 76 has a front end portion 761 and a rear end portion 762. When the push rod base 3 is in a relatively unfolded state relative to the rear connection base 22, the space enclosed by the front end portion 761 and the second end 752 clamps the convex shaft 74, so as to limit the third transmission piece 73 and ensure the stability and reliability of the baby stroller in the unfolded state. During the process of the push rod base 3 rotating and approaching the rear connection base 22, the front end portion 761 and the second end 752 release the convex shaft 74 and the first end 751 pushes the convex shaft 75, so that the third traction piece 73 moves, and further makes the third traction piece 73 pull the seat support base 6 and the seat assembly 8 to fold through the first traction piece 71 and the second traction piece 72.

[0036] AsFigure 5 and Figure 6 As shown, the front connecting seat 12, the rear connecting seat 22 and the push rod seat 3 are rotatably connected to each other around the first axis A through the connecting shaft 10, and the first transmission plate 51 is provided with an arc-shaped clearance groove 55 for the connecting shaft 10 to pass through, ensuring that the first transmission plate 51 will not interfere with the connecting shaft 10 when rotating relative to the rear connecting seat 22, ensuring that the folding action can be completed reliably.

[0037] like Figure 5 、 Figure 8 and Figure 10 As shown, the stroller also has a locking device. After the locking device is unlocked, the push rod assembly 4 can be rotated backward to move the stroller from the unfolded position to the folded position. The locking device can adopt a variety of locking structures used in traditional stroller structures. In this embodiment, a new locking structure is provided. In this embodiment, the locking device includes a first card slot 91 provided on the push rod seat 3 and a second card slot 92 provided on the front connecting seat 12. A card rod 93 is inserted into the first card slot 91 and the second card slot 92. The push rod seat 3 is also provided with a first clearance space 94 that communicates with the first card slot 91. The front connecting seat 12 is provided with a second clearance space 95 that communicates with the second card slot 92. The push rod seat 3 is provided with a card slot that can push the card rod 93 out of the first card slot 91. The card slot 91 and the second card slot 92 allow the card rod 93 to enter the first make way space 94 and the second make way space 95 of the pushing seat 96. The lower end of the upper push rod 42 is provided with a pushing portion 43 that can push the pushing seat 96 when it slides in the downward push rod 41. When the push rod seat 3 rotates and approaches the rear connecting seat 22, the card rod 93 is in the first make way space 94 and the second make way space 95 and the pushing seat 96 is disengaged from the card rod 93. The two ends of the card rod 93 are slidably connected to the rear connecting seat 22. A first return spring 97 that can push the pushing seat 96 to return to its original position is provided between the push rod seat 3 and the pushing seat 96. When the stroller needs to be folded, the upper push rod 42 slides downward, the pushing portion 43 pushes the pushing seat 96, and the pushing seat 96 pushes the clamping rod 93 out of the first and second clamping grooves 91 and 92, and the clamping rod 93 enters the first and second clearance spaces 94 and 95. At this time, the locking device is unlocked, and the push rod assembly 4 can rotate backward. During the rotation process, the pushing seat 96 disengages from the clamping rod 93, and the pushing seat 96, the push rod seat 3, and the push rod assembly 4 rotate relative to the rear connecting seat 22, thereby folding the stroller. The provision of the first and second clearance spaces 94 and 95 ensures that the push rod seat 3 and the front connecting seat 12 will not collide with or interfere with the clamping rod 93 when they rotate.

[0038] like Figure 10As shown, the rear connecting seat 22 is provided with a slide groove 98, and the two ends of the clamping rod 93 are connected to sliders 99 that can slide in the slide groove 98. The slide groove 98 is also provided with a second return spring 90 that can push the slider 99 to move and return. When the pushing seat 96 pushes the clamping rod 93, the clamping rod 93 slides relative to the rear connecting seat 22 together with the slider 99, ensuring reliable movement of the clamping rod 93.

[0039] like Figure 9 and Figure 10 As shown, the push seat 96 is provided with an insertion groove 961 for the card rod 93 to be inserted into and capable of pushing the card rod 93. The push seat 96 is also provided with an opening 962 that communicates with the insertion groove 961 and can allow the card rod 93 to enter when the push rod seat 3 rotates and expands relative to the rear connecting seat 22. The opening 962 has an inclined slanted wall 963. When the push seat 96 slides downward, the groove wall of the insertion groove 961 pushes the card rod 93 downward, thereby disengaging the card rod 93 from the first and second slots 91, 92. When the card rod 93 enters the first and second clearance spaces 94, 95, the card rod 93 exits from the opening 962 as the push rod seat 3 rotates. When the stroller needs to be unfolded, the push rod seat 3 rotates in the opposite direction, and the inclined wall 963 touches the card rod 93 to guide the card rod 93 into the insertion groove 961, and the card rod 93 is finally reset to the first card groove 91 and the second card groove 92 under the action of the first return spring 97 and the second return spring 90.

[0040] like Figure 1 As shown, the rear end of the seat support 6 is provided with a handle 61. After the locking mechanism is unlocked, the handle 61 can be lifted upward, and the push rod assembly 4 can rotate backward under the action of gravity and close to the rear legs 21. During this process, the front legs 11, the seat support 6, and the seat assembly 8 also rotate and close to the front legs 11 through the action of the transmission assembly and the traction assembly 7. Therefore, the folding operation is very convenient and quick by simply sliding the upper push rod 42 downward to impact the push seat 96 and then lifting the handle 61 upward.

[0041] The embodiment is described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiment. Various changes can be made within the knowledge of ordinary technicians in the technical field without departing from the present invention.
