For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] The following is combined with Figures 1 to 9 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] refer to Figures 1 to 5The embodiment of the present application discloses an adjustable leg support mechanism, which is mainly used in a child safety seat to support the legs of a child. The adjustable leg support mechanism includes a leg support gear member 10 and a leg support plate 20. The leg support gear member 10 is used to connect with the ISOFIX anchor point 60. The leg support gear member 10 is provided with a plurality of gear buckle groups 11 distributed in an arc around a preset transverse axis O. Each gear buckle group 11 includes at least two gear buckles 110 arranged along the transverse direction of the leg support gear member 10; the leg support plate 20 is provided with a gear slot group 21. Each gear slot group 21 includes at least two gear slots 210 arranged along its own transverse direction. The gear slot group 21 can be selectively matched with any gear buckle group 11 so that the gear buckle 110 and the gear slot 210 are buckled in a one-to-one correspondence.

[0039] In this way, by connecting the leg support shift piece 10 with the ISOFIX anchor point 60 of the car, and then selecting which shift buckle group 11 to cooperate with the shift slot group 21, the leg support plate 20 is fixed relative to the leg support shift piece 10 through the engagement of the shift buckle 110 with the shift slot 210, thereby realizing the angle adjustment of the leg support plate 20. The leg support plate 20 supports the child's legs at different angles, thereby improving the child's riding experience.

[0040] In this embodiment, the leg support stopper 10 is connected to the ISOFIX anchor point 60 through the adjustment hook 30. Specifically, the adjustment hook 30 is connected to the leg support stopper 10 through a strapping method, and the end of the adjustment hook 30 away from the leg support stopper 10 is used to connect to the ISOFIX anchor point 60. Among them, since the adjustment hook 30 is connected to the leg support stopper 10 through a strapping method, and the strapping method connection is a process method that utilizes the flexibility and strength of a belt-like material (such as a belt, a webbing, a metal belt, etc.), passes the belt 40 through a belt buckle, a hook buckle, a plate buckle or other structures or components, and utilizes the belt 40 itself to wrap around, cross, fix, etc., to connect or bundle two or more objects. It has the characteristics of simple and convenient operation. At the same time, the length of the belt 40 can be adjusted to adapt to the depth of different car seats. In this way, the adjustment hook 30 can adaptively select different directions and distances relative to the leg support stopper 10.

[0041] Combination Figure 6In this embodiment, two limiting portions 211 opposite to each other along the longitudinal direction of the leg support plate 20 are provided on the inner wall of the shift groove 210, and a matching cavity 213 is formed between the two limiting portions 211. The internal space of the shift groove 210 except the matching cavity 213 in the lateral direction is used as an introduction cavity 212, and the shift buckle 110 slides to the matching cavity 213 through the introduction cavity 212. The introduction cavity 212 has a guiding function of guiding the shift buckle 110 to move toward the matching cavity 213, and then the shift buckle 110 and the shift groove 210 are matched by abutting the surface of the shift buckle 110 and the limiting portion 211 facing away from the leg support shift piece 10, thereby completing the assembly of the leg support plate 20 and the leg support shift piece 10.

[0042] Combination Figure 7 and Figure 8 The surfaces of the two limiting parts 211 close to each other are provided with limiting protrusions 214, and the gear buckle 110 is located on the side of the limiting protrusions 214 away from the introduction cavity 212, and the limiting protrusions 214 are used to abut against the gear buckle 110. In this way, the limiting protrusions 214 abut against the gear buckle 110, so as to limit the range of movement of the part of the gear buckle 110 that is used to pass through the matching cavity 213 in the matching cavity 213, and play the role of preventing the gear buckle 110 from escaping from the matching cavity 213 and entering the introduction cavity 212 without operation.

[0043] The gear buckle 110 includes a connected connecting rod 111 and a locking portion 112. The connecting rod 111 passes through the matching cavity 213, and the locking portion 112 abuts against the surface of the limiting portion 211 facing away from the leg support gear member 10. The longitudinal outer diameter of the locking portion 112 is greater than the longitudinal outer diameter of the connecting rod 111. The connecting rod 111 passes through the matching cavity 213, and the locking portion 112 abuts against the surface of the limiting portion 211 facing away from the leg support gear member 10, so that the leg support plate 20 and the leg support gear member 10 are combined more stably.

[0044] Optionally, the surface of the limiting portion 211 facing away from the leg support shift member 10 is recessed relative to the surface of the leg support plate 20 facing away from the leg support shift member 10 and a preset distance is left, so that the shift buckle 110 is flush or recessed relative to the surface of the leg support plate 20 facing away from the leg support shift member 10. This ensures that the locking portion 112 of the shift buckle 110 will not protrude from the surface of the leg support plate 20, thereby facilitating the setting of the leg support pad 50 on the leg support plate 20.

[0045] Exemplarily, the leg support plate 20 is provided with two gear slot groups 21 arranged longitudinally thereof, and the two gear slot groups 21 can be selectively matched with any adjacent two of the gear buckle groups 11. In this way, it can be ensured that the leg support plate 20 and the leg support gear member 10 have a sufficient number of buckling points, and the reliability of the two after assembly is better.

[0046] Optionally, the leg support stopper 10 has four stopper groups 11, so that the leg support plate 20 can have three angles relative to the leg support stopper 10 (for example Fig. 9 ), thus meeting the use requirements of three angles.

[0047] Of course, the number of the gear buckle groups 11 on the leg support gear member 10 can be two, three or more than five; the number of the gear slot groups 21 on the leg support plate 20 can also be one or more than three, and the present application does not make any specific restrictions on this.

[0048] In this embodiment, the leg support shift member 10 has a plurality of first mating surfaces 12 which are surrounded by a preset transverse axis O and connected in sequence at an angle, and each first mating surface 12 has a shift buckle group 11; the leg support plate 20 has a second mating surface 22, and the second mating surface 22 is provided with a shift groove group 21, and the second mating surface 22 can be selectively fitted with any first mating surface 12, so that the contact stability between the leg support shift member 10 and the leg support plate 20 is ensured by the fitting of the mating surfaces.

[0049] Among them, since the leg support plate 20 has two gear groove groups 21 in the embodiment shown in the accompanying drawings, the leg support plate 20 also has two corresponding first mating surfaces 12, and the two first mating surfaces 12 are connected at an angle, so that the leg support plate 20 has higher mating stability by simultaneously contacting and mating with the two surfaces of the leg support gear member 10 through two surfaces.

[0050] In addition, in an embodiment of the present application, the adjustable leg rest mechanism also includes a leg rest pad 50, which is made of a flexible or elastic material. The leg rest pad 50 covers the surface of the leg rest plate 20 facing away from the leg rest shifter 10, so that the child's legs are softer and more comfortable when resting on the leg rest pad 50.

[0051] The embodiment of the present application further discloses a child safety seat, which includes the adjustable leg support mechanism of the above embodiment and thus also has corresponding structure and beneficial effects, which will not be described in detail here.

[0052] In summary, the embodiments of the present application disclose an adjustable leg support mechanism and a child safety seat, which connects the leg support shift piece 10 to the ISOFIX anchor point 60 of the car, and then selects which shift buckle group 11 the shift slot group 21 cooperates with, and the leg support plate 20 is fixed relative to the leg support shift piece 10 through the engagement of the shift buckle 110 with the shift slot 210, thereby achieving angle adjustment of the leg support plate 20 and improving the riding experience of the child.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
