[0031] The present invention will be described in detail below with reference to specific embodiments and accompanying drawings.

[0032] like Figures 1 to 6 As shown, this utility model discloses a child seat 100, which includes a backrest 1 and a headrest 2 that is movably connected to the backrest 1. A height adjustment mechanism is provided between the headrest 2 and the backrest 1. The height adjustment mechanism includes a rack 21 extending vertically on the headrest 2, a stop member 3 that is movably connected to the backrest 1, and a reset elastic member 4 provided between the stop member 3 and the backrest 1. A positioning part 31 is provided on the side of the stop member 3 facing the rack 21, and the positioning part 31 is configured to engage with the rack 21.

[0033] In this embodiment, the headrest 2 includes a body 22 and an adjustment member 23 connected to the body 22. The body 22 is a child's pillow, and the adjustment member 23 is provided with the rack 21. The backrest 1 is provided with an upward-opening and vertically extending adjustment groove 11. The adjustment member 23 can be moved vertically into the adjustment groove 11, thereby realizing the purpose of the headrest 2 being able to move vertically relative to the backrest 1. The stop member 3 is connected to the inner wall of the adjustment groove 11.

[0034] Preferably, the inner wall of the adjustment groove 11 is provided with a receiving groove 12 on the side facing the rack 21, and the stop member 3 is positioned relatively movable in the receiving groove 12 on the side opposite to the rack 21. This arrangement ensures that the stop member can only move back and forth along the receiving groove 12 without tilting up and down, thereby ensuring the stability of the engagement between the stop member 3 and the rack 21, and thus ensuring the reliability of the headrest 2's height adjustment performance. In this embodiment, the reset elastic member 4 is a compression spring, located within the receiving groove 12, with one end abutting against the side wall of the receiving cavity and the other end connected to the stop member 3.

[0035] In this embodiment, the rack 21 is provided on only one side of the front and rear sides of the adjusting member 23. Correspondingly, the stop member 3 and the reset elastic member 4 are only provided on the inner wall of the corresponding side of the adjusting groove 11. In other embodiments, the rack 21 may be provided on both the front and rear sides of the adjusting member 23. Correspondingly, the stop member 3 and the elastic reset member are connected to both the front and rear sides of the inner wall of the receiving groove 12.

[0036] Because this utility model adopts the above technical solution, under the action of the reset elastic member 4, the shift member always maintains a tendency to move in the direction of the rack 21; when the positioning part 31 of the shift member is opposite to the tooth groove of the rack 21, the shift member 3 moves towards the rack 21, and its positioning part 31 engages with the rack 21. In this way, the height adjustment mechanism positions the headrest 2 at the height relative to the backrest 1, and the headrest 2 is in this height position without external pushing or pressing. When the height of the headrest 2 needs to be adjusted, simply move the adjusting member 23 up and down with a certain force. As the adjusting member 23 moves up and down, the rack 21 first pushes the stop member 3 into the receiving groove 12, thereby causing the positioning part 31 of the stop member 3 to disengage from the original corresponding tooth groove. Then, as the adjusting member 23 continues to move, the positioning part 31 will align with another tooth groove of the rack 21. Under the action of the reset elastic member 4, the stop member 3 moves towards the rack 21, causing the positioning part 31 to engage with the corresponding tooth groove. In this way, the height adjustment and positioning of the headrest 2 relative to the backrest 1 are achieved.

[0037] In other words, because the present invention adopts the above technical solution, when it is necessary to adjust the height of the headrest 2, it is only necessary to move the headrest 2 up and down to make the positioning part 31 of the gear part mesh with the different tooth grooves of the rack 21, without any additional operation. Therefore, the height adjustment operation of the headrest 2 of the present invention is very simple.

[0038] In this embodiment, preferably, the upper and lower side walls of the tooth groove of the rack 21 are set as inclined surfaces or arc-shaped surfaces; or / and, the upper and lower end faces of the positioning part 31 are set as inclined surfaces or arc-shaped surfaces. This configuration allows the adjusting member 23 to move up and down more smoothly, making the height adjustment operation of the headrest 2 easier.

[0039] In this embodiment, the inner wall of the adjusting member 23 opposite to the rack 21 and the corresponding side of the adjusting groove 11 is respectively provided with a vertically extending guide groove 230 and a guide protrusion 110. The guide protrusion 110 is positioned within the guide groove 230 and can be moved vertically relative to each other. With this arrangement, not only does the contact between the left and right side walls of the adjusting groove 11 and the side walls of the adjusting member 23 have a guiding and limiting effect, but the guide groove and the guide protrusion also play a guiding and limiting role. Therefore, the adjusting member 23 will not tilt left, right, forward, or backward during vertical movement, thus ensuring the stability of the headrest 2 height adjustment function.

[0040] Preferably, the backrest 1 includes a main body 13 and a face cover 14 connected to the main body 13, wherein the main body 13 and the face cover 14 together form the adjustment groove 11. The backrest 1 is not designed as a single piece, but rather as two interconnected parts (the main body 13 and the face cover 14), which facilitates assembly, particularly the assembly of the stop member 3 and the reset elastic member 4. In this embodiment, the stop member 3 and the face cover 14 are relatively movably connected, and the reset elastic member 4 is disposed between the face cover 14 and the stop member, i.e., the receiving groove 12 is disposed on the face cover 14.

[0041] A limiting device is also provided between the adjusting member 23 and the backrest 1. The limiting device is configured to prevent the adjusting member 23 from moving upward and detaching from the backrest 1. The limiting device includes a limiting member 15 and a limiting groove 231 respectively disposed on the backrest 1 and the adjusting member 23. One side of the limiting member 15 is located within the limiting groove 231 and can move up and down relative to each other. With this configuration, when the adjusting member 23 moves upward relative to the backrest 1, the headrest 2 cannot move upward further when the limiting member 15 contacts the bottom wall of the limiting groove 231, thereby limiting the maximum height that the headrest 2 can be adjusted upward and preventing the headrest 2 from detaching from the backrest 1.

[0042] The adjusting groove 11 has limiting members 15 respectively provided on the left and right sides of the gear position member on its inner wall. Correspondingly, the limiting groove 231 has two positions, left and right. Preferably, the limiting groove 231 is located on the left and right sides of the rack 21.

[0043] In this embodiment, the limiting member 15 is disposed on the cover 14, and the two limiting members 15 are respectively disposed on the left and right sides of the receiving groove 12.

[0044] like Figure 6 As shown, in this embodiment, the adjusting member 23 is provided with vertically extending grooves, and the rack 21 is at least partially located within these grooves. Gaps are formed between the left and right side walls of the rack 21 and the left and right side walls of the grooves. These gaps on the left and right sides are configured as the left and right limiting grooves 231. This configuration allows the force on the rack 21 (due to the action of the reset elastic member 4, the impact force of the moving stop member against the rack 21) to be more easily dispersed due to the left and right gaps, and also makes the processing of the rack 21 easier.

[0045] In other embodiments, the limiting groove 231 and the limiting member 15 may also be disposed at other suitable positions on the backrest 1 and the adjusting member 23.

[0046] In this embodiment, the upper side of the body 22 of the headrest 2 is connected to the upper side of the adjusting member 23, so that, in the vertical direction, except for the upper side, the other parts of the body 22 and the adjusting member 23 are spaced apart front to back. This arrangement ensures that the part of the body 22 connected to the adjusting member 23 is located on the upper side of the backrest 1, while the other parts of the body 22 are located on the front side of the backrest 1. Therefore, when the headrest 2 is moved downwards, when the part of the body 22 connected to the upper side of the adjusting member 23 abuts against the upper end of the backrest 1, the headrest 2 cannot move further downwards, thus achieving adjustment of the lowest height position of the headrest 2. In other embodiments, the headrest 2 can also be prevented from moving further downwards when the limiting member 15 contacts the top of the limiting groove 231. In other words, during the process of the headrest 2 moving downwards, regardless of which engagement is achieved first, the headrest 2 cannot move further downwards. This is achieved by the engagement between the limit member 15 and the limit groove 231 at the lowest height position of the headrest 2, and the engagement between the upper part of the body 22 and the upper part of the adjustment member 23 and the upper end of the backrest 1.

[0047] The adjusting member 23 includes a first connecting portion 24 extending forward and backward, and an adjusting portion 25 extending downward from the rear of the connecting portion. The adjusting portion 25 is provided with the rack 21. The body 22 has a second connecting portion (not shown) extending backward from the top, and the second connecting portion is connected to the first connecting portion 24. In one embodiment, one of the first connecting portion 24 and the second connecting portion may be provided with a slot 240, and the other may be inserted into the slot 240 and connected to it; alternatively, the first connecting member and the second connecting member may be stacked vertically. The first connecting member and the second connecting member may also be connected by any other known and feasible method.

[0048] The child seat 100 also includes a seating section 5, and the lower side of the backrest 1 is connected to the seating section 5. The child seat 100 also includes an armrest 6 connected to the backrest 1 at the rear. The connection method between the seating section 5, the armrest 6 and the backrest 1 can be any known and feasible structure, and is not the inventive point of this utility model, so it will not be described in detail here.

[0049] The child seat 100 also includes a connector 7, the upper side of which is connected to the backrest 1 and the lower side of which is connected to the seating portion 5. Furthermore, the upper side of the connector 7 is connected to the rear side of the backrest 1, and the lower side is connected to the rear side of the seating portion 5.

[0050] Combination Figure 13 As shown, this utility model also discloses a children's stroller, which includes a frame 200 and the aforementioned child seat 100, wherein the child seat 100 is connected to the frame 200.

[0051] The connecting member 7 of the child seat 100 is connected to the frame 200. In this embodiment, the connecting member 7 is provided with a through mounting hole (not shown in the figure), and the frame 200 includes a support tube 8 extending vertically. The connecting member 7 is sleeved on the outside of the mounting tube through the through hole. Other connection relationships between the connecting member 7 and the support tube 8 are not the inventive point of this utility model and can be any known and feasible structure, so they will not be described in detail here.

[0052] The frame 200 also includes a base bracket 9, a front wheel 91 and a rear wheel 92 respectively connected to the front and rear sides of the base bracket 9, and the lower side of the support tube 8 is pivotally connected to the base bracket 9.

[0053] The frame 200 also includes a push handle tube 81 that is movably connected to the support tube 8 on its lower side, a push handle 82 connected to the upper end of the push handle tube 81, and a canopy 83 connected to the push handle 82. The connection structure of these components can also be any known and feasible structure.

[0054] Those skilled in the art should understand that the terms "upper," "lower," "left," "right," "front," "back," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
