[ detailed description ] embodiments

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1 to 9, in the present embodiment, a sliding folding seat structure for a stroller comprises a seat connecting support 1 capable of being connected to a frame 10, a seat plate 2 capable of sliding relative to the seat connecting support 1 is connected to the seat connecting support 1, a backrest rod 3 is rotatably connected to the seat plate 2, a side link 4 capable of being rotatably connected to the backrest rod 3 and the seat connecting support 1 is disposed between the backrest rod 3 and the seat connecting support 1, and a first locking device 5 capable of fixing the backrest rod 3 and the seat plate 2 is further included.

The folding baby carriage comprises a seat connecting support which can be connected with a frame, a seat plate which can slide relative to the seat connecting support is arranged on the connecting support, a backrest rod is rotatably connected onto the seat plate, a side connecting rod which can be rotatably connected with the backrest rod and the seat connecting support is arranged between the backrest rod and the seat connecting support, when the seat is folded, the backrest rod is rotatably folded relative to the seat plate, and the seat plate slides backwards in the folding process, so that the backrest rod cannot extend forwards to be longer, the length direction of the folded seat is ensured to be shorter, the size of the folded baby carriage is small, the occupied space of the baby carriage after the baby carriage is folded is further reduced, and the use experience is optimized.

As shown in fig. 1 to 9, in this embodiment, a first joint 21 is connected to the seat plate 2, a second joint 31 capable of rotating relative to the first joint 21 is connected to a lower end of the backrest rod 3, a first cavity is defined between the first joint 21 and the second joint 31, the first locking device 5 includes a spline 51 disposed in the first cavity and capable of moving laterally, a first key slot 211 and a second key slot 311 capable of being engaged with the spline 51 are respectively disposed on the first joint 21 and the second joint 31, and a spring 52 capable of simultaneously engaging the spline 51 with the first key slot 211 and the second key slot 311 when the seat is in an unfolded state is disposed between the spline 51 and the first joint 21; a first unlocking means 6 is included which disengages the spline 51 from the second keyway 311 and thereby allows the back bar 3 to rotate relative to the seat pan 2. When the seat is in the unfolded state, the spring 52 abuts against the spline 51 to enable the spline to be simultaneously positioned in the first key groove 211 and the second key groove 311, so that the backrest rod 3 and the seat plate 2 are relatively fixed and stable in structure.

As shown in fig. 1 to 9, in this embodiment, the first unlocking device 6 includes a rotating member 61 rotatably disposed in the second joint 311 and capable of driving the spline 51 to disengage from the second key slot 311, an inclined block 312 is disposed in the second joint 31, an inclined slot 611 matched with the inclined block 312 is disposed on the rotating member 61, the first unlocking device 6 further includes a steel cable 62 capable of driving the rotating member 61 to rotate, and the backrest rod 3 is provided with a seat folding switch 63 capable of pulling the pull cable 62. The steel rope 62 is driven to move by pushing the seat folding switch 63, so that the rotating piece 61 is driven to rotate, and due to the matching of the chute 611 and the inclined block 312 on the rotating piece 61, in the rotating process of the rotating piece 61 in the second joint 311, the rotating piece 61 can move towards the direction of the spline 51, and the spline 51 is pushed to be separated from the second key slot 311, so that the backrest rod 3 can rotate relative to the seat plate 2 by unlocking.

As shown in fig. 1 to 9, in the present embodiment, the seat connecting bracket 1 is provided with a rail 11, and the seat plate 2 is provided with a slider 22 that can slide on the rail 11. In the embodiment, the guide rail 11 and the slide block 22 are positioned on the same horizontal plane, so that the overall height of the seat assembly can be reduced, and the overall thickness of the whole vehicle can be reduced after the vehicle is folded; of course, the guide rail and the slide block may also be located in the same vertical plane, the transverse width of the seat may be shortened, and the specific arrangement manner is not specifically limited herein, and any sliding manner that the slide block is matched with the guide rail is within the protection scope of the present application.

As shown in fig. 1 to 9, in the present embodiment, the seat connecting bracket 1 is provided with a connecting position 7 so that the seat can be detachably connected with the frame 10; the seat can be detached and used independently.

As shown in fig. 1 to 9, in this embodiment, the folding seat further includes an armrest assembly 8, a first connecting rod 81 capable of sliding in the armrest assembly 8 is disposed at an end of the armrest assembly 8, the other end of the first connecting rod 81 is rotatably connected to the second joint 31, a second connecting rod 82 capable of rotatably connecting the armrest assembly 8 and the seat plate 2 is disposed between the armrest assembly 8 and the seat plate 2, a third connecting rod 83 capable of rotatably connecting the armrest assembly 8 and the second joint 31 is disposed between the armrest assembly 8 and the second joint 31, and when the back rest rod 3 rotates relative to the seat plate 2, the armrest end of the armrest assembly 8 is drawn close to the seat plate 2, so as to minimize the volume of the folded seat.

When the invention is used, the seat is unfolded to the state shown in fig. 1, when the seat needs to be folded, as long as the seat folding switch 63 is pushed upwards, the other end of the steel rope 62 drives the rotating piece 61 to rotate, and further pushes the spline 51 to be separated from the second key slot 311, so that the second joint 31 can rotate relative to the first joint 21, and further the backrest rod 3 rotates relative to the seat plate 2, because the side connecting rod 4 capable of rotating relative to the backrest rod 3 and the seat plate 2 is connected between the backrest rod 3 and the seat plate 2, the seat plate 2 slides relative to the seat connecting support 1 while the backrest rod 3 rotates relative to the seat plate 2, and as shown in fig. 7 and 8, the folding of the seat is completed.
