[0039] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0040] like Figure 1-Figure 4 As shown, the child seat of this embodiment is applied to a child stroller and can be fixedly mounted on the frame of the child stroller. The child seat of this embodiment mainly comprises: a seat 1, a backrest 2, an armrest 3 and a locking pin 4. The locking pin 4 is arranged between the seat 1, the backrest 2 and the armrest 3. The backrest 2 can be rotated and adjusted relative to the seat 1, and the armrest 3 can also be rotated and adjusted relative to the seat 1. The rotation center 50 of the backrest 2 is the same as the rotation center 50 of the armrest 3.

[0041] The seat 1 is provided with a first slide groove 10 , which is a long groove and is perpendicular to the rotation center 50 of the backrest 2 and the rotation center 50 of the armrest 3 . One end of the locking pin 4 is in the first slide groove 10 .

[0042] The backrest 2 is arranged on the seat 1 and is rotatably connected, i.e., hinged, to the seat 1. A second slide groove 20 is provided on the backrest 2. Specifically, the second slide groove 20 includes a first arcuate groove section 202, a driving groove section 201, and a second arcuate groove section 203 which are connected in sequence. The locking pin 4 is slidably arranged in the first arcuate groove section 202, the driving groove section 201, and the second arcuate groove section 203.

[0043] The armrest 3 is rotatably arranged on the backrest 2 or the seat 1 , and a third sliding groove 30 is provided on the armrest 3 .

[0044] The locking pin 4 is movably disposed in the first sliding groove 10 , the second sliding groove 20 and the third sliding groove 30 . Specifically, one end of the locking pin 4 is in the first sliding groove 10 , and the other end of the locking pin 4 is in the third sliding groove 30 .

[0045] like Figure 4-Figure 6 As shown, when in use, when the backrest 2 is rotated and folded toward the seat 1, the backrest 2 can drive the locking pin 4 and drive the armrest 3 to rotate and fold toward the seat 1; when the backrest 2 is rotated and unfolded away from the seat 1, the backrest 2 can drive the locking pin 4 and drive the armrest 3 to rotate and unfold away from the seat 1.

[0046] In the child seat of this embodiment, a first slide groove 10, a second slide groove 20 and a third slide groove 30 are respectively provided on the seat 1, the backrest 2 and the armrest 3, and the locking pin 4 is movably inserted into the first slide groove 10, the second slide groove 20 and the third slide groove 30. When the backrest 2 is rotated and folded toward the seat 1, the backrest 2 drives the locking pin 4, and drives the armrest 3 to rotate and fold toward the seat 1 through the locking pin 4; when the backrest 2 is rotated and unfolded toward the seat 1, the backrest 2 drives the locking pin 4, and drives the armrest 3 to rotate and unfold toward the seat 1 through the locking pin 4. The armrest 3 can be automatically folded and unfolded during the folding and unfolding process of the backrest 2. The folding and unfolding operations are simple, and the overall structure is simple.

[0047] like Figure 3-Figure 6As shown, in this embodiment, the second chute 20 includes a driving slot section 201, and the driving slot section 201 is located in the middle of the second chute 20. When the lock pin 4 is in the driving slot section 201 and the backrest 2 rotates relative to the seat 1, the backrest 2 can drive the armrest 3 to rotate through the lock pin 4, that is, when the backrest 2 rotates, the backrest 2 squeezes the lock pin 4 through the side wall of the driving slot section 201, so that the lock pin 4 slides, and then the lock pin 4 drives the armrest 3 to rotate, so as to unfold or fold the armrest 3. Specifically, the driving slot section 201 gradually moves away from the rotation center 50 of the backrest 2 from one end to the other end, and the driving slot section 201 is preferably arc-shaped. The second chute 20 also includes a first arc-shaped slot section 202 connected to one end of the driving slot section 201, and the center of the first arc-shaped slot section 202 is at the rotation center 50 of the backrest 2. When the lock pin 4 is in the first arcuate slot section 202 and the backrest 2 rotates relative to the seat 1, the relative position of the lock pin 4 in the first arcuate slot section 202 changes, and the inclination angle of the armrest 3 relative to the seat 1 remains unchanged. The second slide slot 20 also includes a second arcuate slot section 203, the center of which is located at the rotation center 50 of the backrest 2, and the end of the driving slot section 201 away from the first arcuate slot section 202 is connected to the second arcuate slot section 203. When the armrest 3 is folded, the lock pin 4 is in the second arcuate slot section 203; when the armrest 3 is fully unfolded, the lock pin 4 is in the first arcuate slot section 202.

[0048] During actual use, when the locking pin 4 is in the first arc-shaped groove section 202, the backrest 2 rotates relative to the seat 1, and the armrest 3 will not be driven to rotate through the locking pin 4; when the locking pin 4 is in the driving groove section 201, the backrest 2 rotates relative to the seat 1, and the armrest 3 will be driven to rotate through the locking pin 4; when the locking pin 4 is in the second arc-shaped groove section 203, the backrest 2 rotates relative to the seat 1, and the armrest 3 will not be driven to rotate through the locking pin 4.

[0049] The third slide groove 30 of this embodiment gradually moves away from the rotation center 50 of the armrest 3 from one end to the other end. When the lock pin 4 slides from one end to the other end of the third slide groove 30, the armrest 3 can be driven to rotate. Specifically, the backrest 2 squeezes the lock pin 4 through the driving groove section 201, and the lock pin 4 slides along the third slide groove 30, while driving the armrest 3 to rotate relative to the seat 1. One end of the third slide groove 30 has a locking groove section 301. When the lock pin 4 is in the locking groove section 301, the lock pin 4 locks the tilt angle of the armrest 3 relative to the seat 1; when the lock pin 4 slides away from the locking groove section 301, the lock pin 4 releases the lock on the armrest 3.

[0050] The principle of automatic folding and unfolding of the armrest 3 of the child seat is:

[0051] like Figure 4As shown, at this time, the lock pin 4 is in the locking groove section 301 of the third slide groove 30 on the armrest 3, and the lock pin 4 locks the armrest 3, and the armrest 3 is in a fully extended state. When the backrest 2 continues to rotate backward, the position of the lock pin 4 in the first arc-shaped slide groove changes, but the backrest 2 cannot drive the armrest 3 to rotate, ensuring that the armrest 3 has a good protection effect regardless of whether the child is lying or sitting in the seat. If the backrest 2 is rotated forward for folding adjustment, the lock pin 4 will be disengaged from the locking groove section 301 under the action of the driving groove section 201 on the backrest 2, that is, the armrest 3 is unlocked (as shown in FIG. Figure 5 As shown in FIG. 1 , during the process of the backrest 2 rotating and folding toward the seat 1, the relative position of the lock pin 4 in the driving slot section 201 changes, and the backrest 2 drives the armrest 3 to rotate toward the seat 1 through the lock pin 4, the armrest 3 is automatically folded, and the position of the lock pin 4 in the first slide slot 10 on the seat 1 also changes. Figure 6 In the state shown, the locking pin 4 is disengaged from the driving slot section 201 and enters the second arc-shaped slot section 203, and the locking pin 4 reaches the end of the first slide slot 10, and the armrest 3 is folded. The process of automatically unfolding the armrest 3 is opposite to the process of automatically folding the armrest 3, which will not be described in detail here.

[0052] In this solution, the armrest 3 of the child seat can be automatically folded and unfolded as the backrest 2 is folded and unfolded. The folding and unfolding operations are simple and convenient, and the overall structure is simple.
