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

[0035] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0036] refer to Figures 1 to 3The embodiment of the present application discloses an adjustable footrest mechanism, which is mainly used in child safety seats to support the feet of children. The adjustable footrest mechanism includes a footrest gear member 10 and a foot pedal 20. The footrest gear member 10 is used to connect with the ISOFIX anchor point 50, wherein the footrest gear member 10 is provided with a plurality of gear adjustment groups 110 arranged vertically in sequence, and each gear adjustment group 110 includes at least two gear slots 111 arranged horizontally; the foot pedal 20 has a buckling group, which includes at least two buckles 21 arranged horizontally, and the buckling group can be selectively matched with any gear adjustment group 110 to make the buckles 21 buckle with the gear slots 111 in a one-to-one correspondence.

[0037] In this way, by connecting the footrest shift member 10 to the ISOFIX anchor point 50 of the car, and then selecting which gear adjustment group to cooperate with the buckle group according to the length of the child's legs hanging down after sitting on the safety seat, the footrest 20 is fixed relative to the footrest shift member 10 by the buckle 21 and the gear groove 111. In this way, the child's feet can step on the footrest 20, and the child is supported by the footrest 20, thereby improving the child's comfort and avoiding the risk of injury to the child's legs and feet due to hanging in the air.

[0038] In an embodiment, the pedal shift member 10 is presented as an L-shaped plate, that is, the pedal shift member 10 includes a main board body 11 and a connecting portion 12 connected at an angle, and the inner angle formed between the main board body 11 and the connecting portion 12 is used to cooperate with the front outer angle of the seat basin of the child seat, so as to ensure that the shape of the angle transition between the foot shift member 10 and the upper surface and the front surface of the seat basin is adapted, and the connecting portion 12 is used to connect with the ISOFIX anchor point 50, and the main board body 11 is provided with a plurality of gear adjustment groups 110 to achieve the fixation of the main board body 11 and the foot pedal 20 by the engagement of the gear groove 111 and the buckle 21.

[0039] In order to realize the connection between the pedal shifter 10 and the ISOFIX anchor point 50, in this embodiment, the adjustable pedal mechanism further includes an adjustment hook 30, which is connected to the pedal shifter 10 by a threading method, and the end of the adjustment hook 30 away from the pedal shifter 10 is used to connect to the ISOFIX anchor point 50. Among them, since the adjustment hook 30 is connected to the pedal shifter 10 by a threading method, and the threading method connection is a process method that utilizes the flexibility and strength of a belt-shaped 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, which has the characteristics of simple and convenient operation, and the length of the belt 40 can be adjusted to adapt to the depth of different car seats, so that the adjustment hook 30 can adaptively select different directions and distances relative to the pedal shifter 10.

[0040] Combination Figure 4 The gear slot 111 on the pedal gear member 10 includes a vertically connected introduction section 112 and a matching section 113. The lateral inner diameter of the introduction section 112 is larger than the lateral inner diameter of the matching section 113. The plug buckle 21 slides into the matching section 113 through the introduction section 112. In this way, when the plug buckle 21 and the gear slot 111 are buckled, the plug buckle 21 is first aligned with the introduction section 112 and inserted, and then a force from the introduction section 112 to the matching section 113 is applied to the pedal 20, and the plug buckle 21 can slide into the matching section 113. In this way, the plug buckle 21 can abut against the surface of the main body 11 of the pedal gear member 10 that is opposite to the pedal 20, thereby achieving the buckling of the plug buckle 21 and the matching section 113. The introduction section 112 has the effect of guiding the moving direction of the plug buckle 21, which is convenient for the assembly of the pedal gear member 10 and the pedal 20.

[0041] Among them, two laterally opposite limiting protrusions 114 are arranged on the inner wall of the mating section 113. Specifically, the limiting protrusion 114 can be arranged at the junction of the introduction section 112 and the mating section 113, and the buckle 21 is located on the side of the limiting protrusion 114 away from the introduction section 112. In this way, the limiting protrusion 114 abuts against the buckle 21, thereby limiting the range of movement of the part of the buckle 21 that passes through the mating section 113 in the mating section 113, thereby preventing the buckle 21 from detaching from the mating section 113 and entering the introduction section 112 without operation.

[0042] The buckle 21 includes a connected connecting rod 210 and a locking portion 211, the transverse outer diameter of the locking portion 211 is larger than the transverse outer diameter of the connecting rod 210, the connecting rod 210 passes through the matching section 113, and the locking portion 211 abuts against the surface of the pedal shift member 10 facing away from the foot pedal 20, so that the combination of the pedal shift member 10 and the foot pedal 20 is more stable.

[0043] Exemplarily, the foot pedal 20 has two vertically arranged snap-fit ​​groups, which can be selectively matched with any two adjacent gear adjustment groups 110, so as to ensure that the foot pedal 20 and the foot pedal gear member 10 have a sufficient number of snap-fit ​​points, and the reliability of the two after assembly is better.

[0044] The number of the gear adjustment groups 110 on the pedal gear member 10 can be Figure 1 and Figure 3 The seven shown in FIG. 1 can realize the adjustment of six different height gears; of course, the foot pedal 20 can also be provided with one or more than three snap-fit ​​groups, and the number of gear adjustment groups 110 on the foot pedal gear member 10 can also be two, three or other numbers, and the present application does not impose any specific restrictions on this.

[0045] In addition, a weight-reducing hole 13 is provided between two adjacent gear slots 111 in the transverse direction of the pedal gear member 10 , so that the weight and material of the pedal gear member 10 can be reduced, thereby reducing the cost.

[0046] Combination Figures 5 to 8 The adjustable pedal mechanism of the embodiment of the present application can be used in the following process:

[0047] The adjustment hook 30 is connected to the connecting portion 12 of the pedal shift member 10 by threading, and the child safety seat is placed on the car seat as a whole. The length of the strap 40 is adjusted according to the depth of the car seat, and then the adjustment hook 30 is hung on the ISOFIX anchor point 50 and fixed.

[0048] According to the leg length of the child, select the height of the gear slot 111 that the buckle 21 needs to match, and then lay the footrest 20 flat and align the buckle 21 with the lead-in section 112 of the gear slot 111 (refer to Figure 6 ); Push the pedal 20 toward the pedal gear member 10 so that the buckle 21 is inserted into the introduction section 112 (reference Figure 7 ); then, the pedal 20 is pressed downward, so that the connecting rod 210 of the buckle 21 slides from the introduction section 112 over the limiting protrusion 114 to the matching section 113, and the locking portion 211 of the buckle 21 and the pedal 20 are respectively abutted against the two sides of the main body 11 to complete the assembly of the pedal 20 and the pedal shift member 10 (refer to Figure 5 and Figure 8 ).

[0049] The embodiment of the present application also discloses a child safety seat, which includes the adjustable footrest mechanism of the above embodiment and thus also has corresponding structure and beneficial effects, which will not be described in detail here.

[0050] In summary, the embodiment of the present application discloses an adjustable footrest mechanism and a child safety seat, which connects the footrest gear member 10 to the ISOFIX anchor point of the car, and then selects which gear adjustment group to cooperate with the buckle group according to the length of the child's legs hanging down after sitting on the safety seat, and fixes the footrest 20 relative to the footrest gear member 10 by snapping the buckle 21 with the gear groove 111, so that the child's feet can step on the footrest 20, and the child is supported by the footrest 20, thereby improving the child's comfort and avoiding the risk of injury to the child's legs and feet due to hanging in the air.
