Description

Technical Field

[0001] The present invention relates to the technical field of child seats, and in particular to a foldable child seat support leg structure and a use and folding method thereof. Background Art

[0002] A child seat, also known as a child restraint system, is a seat designed for children of different ages (or weights) and installed in a car to effectively improve the safety of children riding in a car. The European regulation ECE R129 defines a child safety seat as: a child safety protection system that can be fixed to a motor vehicle and consists of a seat belt assembly with buckles or flexible components, adjustment mechanisms, accessories, etc. It can be combined with additional devices such as portable cribs, infant carriers, auxiliary seats or collision protection devices. In the event of a car collision or sudden deceleration, it can reduce the impact force on the child and restrict the child's body movement to reduce their injuries and ensure their safety. A child seat with a support leg structure is more stable and safer and can effectively protect children.

[0003] The latest European regulations, ECE R129 / 03, require the use of support legs for groups 0+1 (young children). However, there are size requirements for group 2.3 (medium and older children). The support legs of existing ordinary seats can be rotated and folded, but cannot be fully retracted, resulting in the support legs exceeding the latest size range. According to the size requirements of the latest European regulations, ECE R129 / 03, the support legs must be fully retracted to meet the size requirements. Summary of the Invention

[0004] The object of the present invention is to provide a foldable child seat support leg structure and a method for using and folding the same, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a retractable child seat support leg structure, comprising a seat bottom cover, a slide groove being provided on the front side of the seat bottom cover, and a slide rail being provided inside the slide groove, one end of the slide rail being rotatably connected to a support leg body, a support leg body outer cover being sleeved at the connection between the slide rail and the support leg body, an unlocking spring being provided at the lower end of the support leg body, a first limiting spring being provided on one side of the seat bottom cover at the top of the slide groove, and a second limiting spring being provided on the other side of the seat bottom cover at the top of the slide groove.

[0006] Furthermore, a slide cover is provided on the outside of the slide, and two notches are provided on both sides of the slide.

[0007] Furthermore, an inner recess is provided at one end of the slide rail away from the supporting leg body, a first waist-shaped hole is provided on one side of the top of the slide rail, and a second waist-shaped hole is provided on the other side of the top of the slide rail.

[0008] Furthermore, the unlocking spring is tilted toward a side away from the supporting leg body.

[0009] Furthermore, the first limiting spring piece and the second limiting spring piece are both inclined inwardly, the end of the first limiting spring piece is set to a plane, and the end of the second limiting spring piece is set to an arc surface.

[0010] Furthermore, two buckle plates are provided on both sides of the outer cover of the slide slot, and the buckle plates are inserted into the notches opened in the slide slot, and the buckle plates are buckled on the side edges of the slide rail.

[0011] Furthermore, the second limiting spring piece is inserted into the second waist-shaped hole formed in the slide rail.

[0012] Furthermore, blocking pieces are provided on both sides of the slide groove at the bottom of the seat bottom cover.

[0013] A method for using a stowable child seat support leg structure comprises the following steps:

[0014] Step (A1): Pull the outer cover of the supporting leg body so that the outer cover drives the supporting leg body to move, and the supporting leg body drives the slide rail to slide inside the slide groove;

[0015] Step (B1): During the sliding process of the slide rail and the support leg body, when the first waist-shaped hole abuts against the first limiting spring piece, the slide rail pushes the first limiting spring piece to flatten it until the first limiting spring piece moves out of the first waist-shaped hole. During this period, the support leg body drives the unlocking spring piece to move, so that the unlocking spring piece contacts and presses against the first limiting spring piece;

[0016] Step (C1), while the first limiting spring piece moves out from the first waist-shaped hole, the second limiting spring piece abuts against one side of the second waist-shaped hole;

[0017] Step (D1): Rotate the support leg body again, so that the support leg body drives the unlocking spring to move, and the unlocking spring no longer presses against the first limiting spring, so that the first limiting spring returns to an inclined state and presses against the inner recess of the slide rail. The first limiting spring and the second limiting spring limit the slide rail so that the slide rail no longer slides.

[0018] Step (E1): rotate the support leg body to a vertical position to support the seat bottom cover.

[0019] A method for storing a storable child seat support leg structure comprises the following steps:

[0020] Step (A2): rotating the support leg body so that the support leg body drives the unlocking spring to rotate until the support leg body rotates to a horizontal state;

[0021] Step (B2): After the supporting leg body rotates to a horizontal state, the unlocking spring contacts and presses against the first limiting spring, flattening it so that the first limiting spring no longer presses against the inner recess of the slide rail;

[0022] Step (C2): Push the outer cover of the supporting leg body again, so that the outer cover pushes the supporting leg body to move, and the supporting leg body drives the slide rail to move until the first limiting spring piece is stuck in the first waist-shaped hole;

[0023] Step (D2): During the movement of the supporting leg body, the supporting leg body drives the unlocking spring to move, so that the unlocking spring no longer presses against the first limiting spring. When the first limiting spring is inserted into the first waist-shaped hole, the first limiting spring returns to the tilted state.

[0024] Step (E2): Continue to push the outer cover of the support leg body until the outer cover of the support leg body rests against the seat bottom cover, and store the support leg body at the bottom of the seat bottom cover.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention is provided with a slide groove and a slide rail, which are rotatably connected to the support leg body through the slide rail. The support leg body is rotated into the slide rail, the limit of the slide rail is released, and then the slide rail is pushed to slide inside the slide groove. The support leg body is carried by the slide rail and stored at the bottom of the seat bottom cover, so that the support leg can be completely retracted to meet the specified size and meet the usage requirements;

[0027] 2. The present invention is provided with an unlocking spring piece, a first limiting spring piece and a second limiting spring piece. The first limiting spring piece and the second limiting spring piece are used to limit the slide rail to prevent the slide rail from sliding when the support leg is in use. By rotating the support leg body, the unlocking spring piece is pressed against the first limiting spring piece to release the limit of the slide rail, making it convenient to store the support leg.
