[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] It should be noted that in the claims and description of this patent, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus. In the absence of further restrictions, an element defined by the phrase "comprising a" does not exclude the presence of other identical elements in the process, method, article or apparatus comprising the element.

[0043] like Figures 1-4 As shown, this embodiment discloses a child seat with adjustable seating position, which can be in the form of an infant carrier or a child safety seat. The child seat with adjustable seating position includes a housing 1, a seat cushion 2, a backrest 3, a first rotation axis 31, a second rotation axis 41, a third rotation axis 42, a fourth rotation axis 7, and a swing arm 4.

[0044] The housing 1 and backrest plate 3 are rotatably connected via a first rotation axis 31. The seat plate 2 and backrest plate 3 are rotatably connected via a fourth rotation axis 7. A second rotation axis 41 and a third rotation axis 42 are rotatably mounted on each end of the swing arm 4. The second rotation axis 41 is rotatably connected to the seat plate 2. The third rotation axis 42 is rotatably connected to one end of the housing 1.

[0045] The housing 1, seat plate 2, backrest plate 3, first rotation axis 31, second rotation axis 41, third rotation axis 42, fourth rotation axis 7, and swing arm 4 together form a four-bar linkage. Due to the characteristics of the four-bar linkage, when the housing 1 is fixed, the seat plate 2 and backrest plate 3 can move within a predetermined range.

[0046] The child riding device of this embodiment adopts the above-mentioned structural form, and the angle fixation of the seat cushion plate 2 and the backrest plate 3 can be easily adjusted as needed, thereby adjusting the sitting posture of the child.

[0047] Furthermore, in this embodiment, a guide groove is provided on the shell 1, and the child riding device of this embodiment also includes a pin 6 slidably inserted in the guide groove, and the pin 6 slides in the guide groove, thereby limiting the movement trajectory and range of the backrest board 3.

[0048] Furthermore, in this embodiment, the guide groove is provided with two shift holes, one at each end of the guide groove, but the present invention is not limited thereto and the number and position of the holes can be flexibly adjusted according to actual needs. When the pin 6 slides into the shift hole, it can be locked to fix the angle between the seat cushion plate 2 and the backrest plate 3, thereby fixing the angle between the seat cushion plate 2 and the backrest plate 3 at a predetermined use position.

[0049] In this embodiment, multiple (two) gear holes are provided, namely, a first gear hole 81 and a second gear hole 82. Therefore, the tilt angle between the seat cushion plate 2 and the backrest plate 3 can be quickly switched between multiple (two) preset angles, making the adjustment faster.

[0050] Furthermore, the children's riding device of this embodiment further includes a driving member 5, one end of which is provided with an oblique groove, which is arranged to form a cross with the guide groove, and the pin shaft 6 is slidably inserted into the oblique groove.

[0051] In this embodiment, the above-mentioned structural form is adopted, and the position of the pin shaft 6 in the guide groove can be quickly adjusted by the driving member 5.

[0052] Furthermore, in order to improve the stability of the support of the pin shaft 6, the number of guide grooves, pin shafts 6 and inclined grooves is two, and the three are arranged in a one-to-one correspondence, that is, one pin shaft 6 is inserted into a guide groove and an inclined groove, and another pin shaft 6 is inserted into another guide groove and another inclined groove.

[0053] Furthermore, in order to improve the stability of the connection between the shell 1 and the seat cushion 2, the number of the second rotating shaft 41 and the third rotating shaft 42 are both two, and they are symmetrically arranged in groups of two at the two connection positions of the seat cushion 2 and the shell 1, that is, one second rotating shaft 41 and one third rotating shaft form a group, and another second rotating shaft 41 and another third rotating shaft form another group.
