As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

In this application, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any particular order or number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless explicitly specified otherwise.

Referring to fig. 1 to 7 and 13, the present application provides a child seat having an unfolded state and a folded state, including a seat 200 for supporting the buttocks of a child, a backrest 100 for supporting the back of the child, and a safety bar 300 for blocking the child from leaving the seat. In the unfolded state, the seat 200 is far away from the backrest 100, and the safety bar 300 is located between the seat 200 and the backrest 100, and in the folded state, the three are close to each other.

The joints disposed on two sides of the child seat for connecting the backrest 100, the seat 200 and the safety lever 300 comprise a first pivot 310, a second pivot 210 and a third pivot 110 coaxially pivoted in sequence, the axis is defined as a rotation axis 101, the first pivot 310 has a first lock pin 320 axially penetrating through the second pivot 210 to reach the third pivot 110, on a rotation path of the first lock pin 320, the second pivot 210 and the third pivot 110 have locking surfaces which abut against two sides of the first lock pin to limit the rotation of the first lock pin 320 in an unfolded state, and the corresponding second pivot 210 and the corresponding third pivot 110 are limited by the first lock pin 320 and cannot be further unfolded and rotated, so that the backrest 100, the seat 200 and the safety lever 300 connected with the three pivots maintain an unfolded state. The first latch 320 and the first pivot 310 are integrated, and are not a traditional movably-installed latch, thereby eliminating a return spring acting on the traditional latch and simplifying the structure. The second pivoting member 210 and the third pivoting member 110 are not limited in the rotating and folding directions, and can be directly rotated and folded, so as to omit the unlocking member and further simplify the structure.

In this embodiment, the first pivot 310 is connected to the safety bar 300, the second pivot 210 is connected to the seat 200, and the third pivot 110 is connected to the backrest 100. in the unfolded state, the angle between the backrest 100 and the seat 200 is at least greater than 90 degrees, and gravity is used to hold the locking surface against the first locking pin 320.

The second pivot member 210 is provided with a first arc groove 220 using the rotation axis 101 as a circle center, the third pivot member 110 is provided with a second arc groove 120 using the rotation axis 101 as a circle center, the first lock pin 320 passes through the first arc groove 220 and extends into the second arc groove 120, and the two arc grooves have the same radius. The locking surfaces are respectively a first locking surface and a second locking surface, and the first locking surface 221 is one of the groove walls of the first arc groove 220; the second locking surface 121 is one of the groove walls of the second arc groove 120.

Referring to fig. 8 to 10, the other groove wall of the first arc groove 220 is a third locking surface 222, the other groove wall of the second arc groove 120 is a fourth locking surface 122, and in the folded state, the third locking surface 222 and the fourth locking surface 122 abut against two sides of the first locking pin. At this time, the seat 200 and the safety lever 300 are drawn close to the backrest 100 and keep the child seat in a plate shape while being restricted from further rotational folding.

The second pin 230 is protruded from the second pivot 210, and the third arc 130 around the rotation axis 101 is formed in the third pivot 110, which cooperate with each other to guide the rotation between the second pivot 210 and the third pivot 110. In addition to the second lock pin 230 extending and protruding radially, the third pivot 110 is partially embedded in the second pivot 210, so that the third arc-shaped groove 130 is matched with the second lock pin 230, and the third arc-shaped groove 130 has two groove walls, and in the unfolded/folded state, the second lock pin 230 abuts against the corresponding groove wall of the third arc-shaped groove 130, so as to maintain the state of the child seat.

Referring to fig. 3, 4 and 12, the third pivoting member 110 is convexly provided with a first limiting block 111, the second pivoting member 210 is convexly provided with a second limiting block 211 matched with the first limiting block 111, and in the unfolded state, the two limiting blocks abut against each other to limit the seat 200 from rotating downwards, which can also be understood as limiting the seat 200 from further rotating towards the unfolded direction, so that after the child seat is mounted on the frame, the seat 200 maintains a safe sitting angle, and the use safety is improved.

The specific connection mode of the child seat and the frame is as follows: the third pivoting member 110 comprises a connecting member 140 fixedly connected to the backrest 100, and an adapter 150 pivotally connected to the connecting member 140, the adapter 150 being adapted to be mounted on a frame 400 of the child car, wherein the adapter 150 is detachably connected to the frame 400.

Referring to fig. 2, in order to adapt to various riding postures, the backrest 100 can adjust the inclination angle thereof, so as to prevent the backrest 100 from being folded down too much, which causes the seated child to turn down and cause safety accidents. The first stopper 111 is disposed on the adapter 150, the connecting member 140 is convexly disposed with a third stopper 141 abutting against the first stopper 111, and the backrest 100 rotates downward until the third stopper 141 abuts against the first stopper 111 and stops rotating.

The method for adjusting the self-inclination angle of the backrest 100 comprises the following steps: referring to fig. 3, 4 and 14, a locking mechanism for keeping the backrest 100 fixed is provided between the connecting member 140 and the adapter 150, the locking mechanism includes a latch 161, a slot 162 and an elastic member, the latch 161 is slidably mounted on the backrest 100; the slot 162 is adapted to the pin 161 and is disposed on the adapter 150; a resilient member (e.g., a spring) is provided on the backrest 100 and acts on the latch 161 to extend into the slot 162. The number of the slots 162 is plural, which satisfies different inclination angles of the backrest 100, and the elastic member is installed in the backrest 100 and is invisible in an assembled state.

With reference to fig. 14, the connecting member 140 is provided with a mounting hole 142, the adapter 150 has a boss 151 fitted in the mounting hole 142, and the slot 162 is provided on the circumferential surface of the boss 151. The boss 151 has a locking piece 152 constituting a part thereof, the locking piece 152 is fixed to the boss 151 by a screw, and the insertion groove 162 is provided on the locking piece 152 and extends in the radial direction. Because the extending direction of the slot 162 is perpendicular to the extending direction of the boss 151, the locking piece 152 is separately arranged for the slot 162 to open, which is convenient for injection molding.

The utility model provides a children's seat has saved elastic component and has separated the latch fitting to and the corresponding part of separating the latch fitting linkage, has simplified the structure, and then has improved the stability in use.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features. When technical features in different embodiments are represented in the same drawing, it can be seen that the drawing also discloses a combination of the embodiments concerned.

The above examples only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
