Referring to fig. 1-17, the present application provides a foldable stroller including a frame 200 and a seat 1000 mounted to the frame for seating a child. Wherein the frame has opposite folded and unfolded states, the seat 1000 includes a seat cushion 110 and a back rest 120, the seat cushion 110 having opposite front and rear sides, the back rest 120 being rotatably coupled to the rear side of the seat cushion 110 and having a plurality of tilt angles with respect to the seat cushion 110. Wherein the plurality of tilt angles includes different tilt angles in the unfolded state for a child to sit on, and tilt angles that tend to be 0 degrees, corresponding to the folded state in which the backrest 120 is drawn closer to the seat cushion 110.
The seat 1000 further includes a latch mechanism that limits rotation of the back 120 relative to the seat cushion 110 such that the back 120 is maintained at an oblique angle, and a first unlocking member 361 for unlocking the latch mechanism, and the frame 200 has a trigger 260 that moves the first unlocking member 361 during folding. The seat can be folded and linked with the frame or the backrest.
Taking the baby carrier as an example, when the baby carrier is switched to a folding state (shown in fig. 16 and 17) in an unfolding state (shown in fig. 1), the locking mechanism is unlocked by the folding frame, the backrest is driven by gravity or other acting forces to rotate to be close to the seat cushion, the folding of the seat and the seat relative to the frame is completed, the folding operation of the seat is not needed, and the folding operation steps are simplified.
In an embodiment, the seat includes a second unlocking member 362, where the second unlocking member 362 and the first unlocking member 361 are independent of each other, i.e. the two unlocking members do not interfere with each other, and correspond to different operations, e.g. the second unlocking member is used to adjust the backrest inclination in the unfolded state. The two unlocking pieces control the same locking mechanism and are applied to different use scenes, so that the structure is simplified and the operation is convenient.
In an embodiment, an elastic driving member 130 for driving the backrest 120 to flip to one side relative to the seat cushion 110 is disposed between the seat cushion 110 and the backrest 120, and is used for helping to accelerate the backrest 120 to rotate towards the seat cushion 110 when the seat is folded. Particularly, in the case that the backrest 120 is in a substantially vertical state, etc., the backrest cannot be folded along with the frame automatically due to gravity alone is avoided.
In one embodiment, the seat cushion 110 and the backrest 120 are rotatably coupled about a first pivot axis, and the resilient driving member 130 is a coil spring that is sleeved on the first pivot axis, has two force application ends, and is coupled to the seat cushion 110 and the backrest 120, respectively. The first pivot is located on the rear side of the seat cushion 110 such that the arrangement of the coil springs does not interfere with the cloth covers provided on the seat cushion 110 and the backrest 120. The coil spring is sleeved on the first pivot, and the force application direction of the force application end connected with the backrest 120 is close to the rotation direction of the backrest.
The locking mechanism is a one-way locking mechanism and has opposite locking states in which the backrest 120 is restricted from turning backward and the backrest 120 is allowed to turn forward, and unlocking states in which the backrest 120 is allowed to turn backward.
Wherein the elastic driving member 130 drives the backrest 120 to turn backward and accelerate relative to the seat cushion 110, for example, the seat is installed on a baby carrier, and once the locking mechanism is unlocked, the elastic driving member 130 pulls the backrest 120 to complete folding. In the locked state, the backrest 120 is supported by the elastic driving member and the back of the child, so that the backrest 120 can only rotate forward under the action of human force to adjust the inclination angle of the backrest, and the back rotation requires unlocking the locking mechanism and then adjusting the angle of the locking mechanism.
Therefore, when the backrest angle is adjusted by rotating forwards, the seat of the embodiment does not need to unlock the locking mechanism, and the backrest angle adjusting operation is convenient. When the backrest is folded, after the locking mechanism is unlocked, the backrest is acted by the elastic driving piece to rotate and close to the cushion, so that the folding operation is convenient.
