[ detailed description ] embodiments

The invention will be further described with reference to the accompanying drawings:

as shown in fig. 1 to 8 and 16 to 20, a stroller comprises a foldable bottom support frame 1, wherein the bottom support frame 1 comprises a first support frame 11 and a second support frame 12 capable of rotating relative to the first support frame 11, wheels 13 are respectively arranged at the lower ends of the first support frame 11 and the second support frame 12, the bottom support frame 1 is further connected with a push rod assembly 2 capable of rotating and folding relative to the bottom support frame 1, the bottom support frame 1 is further connected with a seat support 5 capable of rotating forward or backward relative to the bottom support frame 1 and folding toward the bottom support frame 1, and the seat support 5 is connected with a seat assembly 6 capable of being folded and rotating and reversing relative to the seat support 5. Seat supporting seat 5 can rotate forward or backward and draw close folding to bottom sprag frame 1 on, so seat subassembly 6 is connected to the seat supporting seat 5 on the back, no matter seat subassembly 6 is towards the place ahead or towards the rear, seat supporting seat 5 all can take seat subassembly 6 directly to fold when push rod subassembly 2 and bottom sprag frame 1 are folding to draw close to bottom sprag frame 1 on, even seat subassembly 6 is towards the rear, also need not be rotatory to the position of orientation the place ahead folding again with seat subassembly 6 for the very convenient and fast of children's shallow folding operation. The folding structure of the bottom support 1 and the push rod assembly 2 may adopt a conventional folding structure, for example, a gear transmission mechanism is arranged among the first support frame 11, the second support frame 12 and the push rod assembly 12, and of course, another folding structure of the push rod assembly 2 and the bottom support 1 will be provided in this embodiment.

As shown in fig. 16 to 20, a control assembly is provided between the seat support 5 and the bottom support frame 1 for controlling the rotation and folding directions of the seat support 5 when the stroller is folded, the control assembly controls the seat support 5 to rotate and fold forward when the seat assembly 6 faces forward and the stroller is folded, and controls the seat support 5 to rotate and fold backward when the seat assembly 6 faces backward and the stroller is folded. When the stroller is folded due to the arrangement of the control assembly, the seat supporting seat 5 can be rotated and folded according to the set direction, so that the folding operation of the stroller is controllable, convenient and smooth.

As shown in fig. 1, the seat assembly 6 includes a seat portion 61 connected to the seat support base 5 and a backrest portion 62 connected to the seat portion 61 and capable of being folded and rotated with respect to the seat portion 61.

As shown in fig. 4 and fig. 9 to 12, the first support frame 11, the second support frame 12, the push rod assembly 2 and the seat support 5 are rotatably connected around the same axis, the push rod assembly 2 is connected with the bottom support frame 1 through the transverse connecting member 3 connected thereto, and the seat support 5 is connected to the transverse connecting member 3 and can rotate relative to the transverse connecting member 3.

As shown in fig. 1, 9 to 12, and 17 to 20, the second support frame 12 includes a left support frame 121 and a right support frame 122, the control assembly includes a left arc-shaped groove 71 provided on the left support frame 121 and extending along the rotation direction of the push rod assembly 2, and a right arc-shaped groove 72 provided on the right support frame 122 and extending along the rotation direction of the push rod assembly 2, the seat support 5 is slidably connected with a left sliding pin 73 capable of moving in the left arc-shaped groove 71 and abutting against the groove wall of the left arc-shaped groove 71 to prevent the seat support 5 from rotating forward, the seat support 5 is further slidably connected with a right sliding pin 74 capable of moving in the right arc-shaped groove 72 and abutting against the groove wall of the right arc-shaped groove 72 to prevent the seat support 5 from rotating backward, a left return spring 75 is provided between the left sliding pin 73 and the seat support 5, a right return spring 76 is provided between the right sliding pin 74 and the seat support 5, seat subassembly 6 on be equipped with and supply left slide pin 73 or right slide pin 74 to get into the groove 77 of stepping down, when left slide pin 73 gets into the groove 77 of stepping down, left slide pin 73 break away from and right slide pin 74 is impressed to right arc groove 72 by seat subassembly 6 with left arc groove 71, when seat subassembly 6 rotates the switching-over and makes right slide pin 74 get into the groove 77 of stepping down relatively to seat supporting seat 5, right slide pin 74 break away from and left slide pin 73 is impressed to left arc groove 71 by seat subassembly 6. When the seat assembly 6 faces forward, an adult pushing the stroller and a child in the seat assembly 6 face in the same direction, at this time, the left sliding pin 73 is separated from the left arc-shaped groove 71, the right sliding pin 74 falls into the right arc-shaped groove 72, the groove wall of the left arc-shaped groove 71 cannot block the left sliding pin 73, the groove wall of the right arc-shaped groove 72 can block the right sliding pin 74, due to the abutting of the sliding pin 74 and the groove wall of the right arc-shaped groove 72, the control assembly can prevent the seat support 5 from rotating backwards and ensure that the seat support 5 can only rotate forwards, when the stroller is folded, the seat support 5 rotates forwards, and the right sliding pin 74 moves in the right arc-shaped groove 72 along the extending direction of the right arc-shaped groove 72, so that the seat assembly 6 is moved forwards on the first support frame 11. When the seat assembly 6 is rotated to make the seat assembly 6 face backward, the adult pushing the stroller faces the child in the seat assembly 6, because the seat assembly 6 rotates relative to the seat support 5, the abdicating slot 77 originally engaged with the left sliding pin 73 moves to the position engaged with the right sliding pin 74, the left sliding pin 73 is pressed into the left arc-shaped slot 71, the right sliding pin 74 is pushed by the right return spring 76 to disengage from the right arc-shaped slot 72, the slot wall of the left arc-shaped slot 71 can abut against the left sliding pin 73, so as to prevent the seat support 5 from rotating forward, and therefore, when the stroller is folded, the seat support 5 can only rotate backward, so that the seat assembly 6 is closed onto the second support frame 12. Therefore, when the stroller is folded, the control assembly automatically controls the rotation direction of the seat support seat 5 according to the orientation direction of the seat assembly 6, so that the defect that the conventional stroller can be folded only by adjusting the seat assembly to the orientation direction when the stroller is folded is overcome, and meanwhile, the folding operation is controllable, convenient and smooth.
