An outer cover structure for adaptive rotation of child seat support legs and its working method

Abstract

The present invention discloses an outer cover structure for adaptive rotation of a child seat support leg and a working method thereof, comprising a support leg body, a top cover provided at the top end of the support leg body, a connector provided on one side of the upper end of the support leg body, a slide rail provided on one side of the connector, and two connecting plates provided at one end of the slide rail. The present invention is provided with a boss and a guide rail, and cooperates with the longitudinal slide groove and the transverse slide groove provided on the support leg outer cover. By rotating the support leg body, the bosses on both sides of the top cover slide inside the longitudinal slide groove and push the support leg outer cover to move. The support leg outer cover is limited in its movement trajectory by the guide rail on the top of the connecting plate, so that the support leg outer cover can be moved out when used as the support leg body rotates, and can be stored together when the support leg body rotates and is stored, thereby reducing the space occupied by the child seat when the support leg body is stored, and facilitating the use of the child seat.

Description

Technical Field

[0001] The present invention relates to the technical field of child seats, in particular to an outer cover structure of a child seat support leg that is adaptive to rotation and a working 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 R44 / 03 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 a portable crib, infant carrier, auxiliary seat or collision protection. 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 in the car. A child seat with a support leg structure is more stable and safer and can effectively protect children.

[0003] The front end of a child seat with a rotating support leg is usually provided with an outer cover for protection. The support leg outer cover is generally fixed to the seat bottom cover. When the support leg is stored in the bottom cover, the outer cover still protrudes outward, increasing the space occupied by the child seat and being not conducive to the use of the child seat. Summary of the Invention

[0004] The object of the present invention is to provide an outer cover structure for adaptively rotating support legs of a child seat and a working method thereof, 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: an outer cover structure for the rotation of an adaptive child seat support leg, comprising a support leg main body, a top cover being provided at the top end of the support leg main body, a connecting piece being provided on one side of the upper end of the support leg main body, and a slide rail being provided on one side of the connecting piece, two connecting plates being provided at one end of the slide rail, the slide rail being rotatably connected to the connecting piece through the connecting plate, a support leg outer cover being sleeved at the connection between the connecting piece and the connecting plate, and longitudinal slide grooves being provided on both sides of the inner wall of the support leg outer cover, the support leg outer cover being provided with a transverse slide groove above the longitudinal slide groove, bosses being provided on both sides of the top cover, and the bosses being provided inside the longitudinal slide grooves provided in the support leg outer cover, a guide rail being provided at the top end of the connecting plate, and the end of the guide rail being provided inside the transverse slide grooves provided in the support leg outer cover.

[0006] Furthermore, the slide rails are provided with notches below the two connecting plates.

[0007] Furthermore, the guide rails at the top ends of the two connecting plates are bent outwards, and the ends of the guide rails are bent into a horizontal state.

[0008] Furthermore, the top of the longitudinal chute is an upper cavity, and the bottom of the longitudinal chute is a lower cavity.

[0009] Furthermore, the width of the transverse sliding groove matches the thickness of the end portion of the guide rail.

[0010] Furthermore, the width of the boss is smaller than the width of the longitudinal chute, and the difference between the width of the boss and the width of the longitudinal chute is 1-3 cm.

[0011] Furthermore, one side of the boss is provided with a chamfer, and the other side of the boss is provided with a curved surface.

[0012] Furthermore, chamfers are provided on both sides of the guide rail.

[0013] A method for operating an outer cover structure capable of adaptively rotating a child seat support leg, including a method for adaptively moving the outer cover when the support leg is in use and a method for adaptively moving the outer cover when the support leg is stored;

[0014] The method for adaptively moving the outer cover when the support legs are in use comprises the following steps:

[0015] In step (A1), in the initial stage, the supporting leg body is placed inside the slide rail in a retracted state, the bosses on both sides of the top cover are located in the lower cavity of the longitudinal slide groove, and the bosses in the lower cavity are in a horizontal state;

[0016] Step (B1), the first part of the adaptive movement phase, involves rotating the support leg body, causing the support leg body to drive the top cover and the connector to rotate. The top cover carries the boss, causing it to slide within the longitudinal slot. The boss gradually tilts during the sliding process and pushes the support leg outer cover outward.

[0017] In step (C1), the second part of the adaptive movement phase, the outer cover of the support leg moves outward while the transverse chute provided on the outer cover of the support leg slides along the end of the guide rail, and the guide rail gradually moves away from the longitudinal chute;

[0018] In step (D1), at the end stage, the top cover rotates with the boss and slides into the upper cavity of the longitudinal slide groove, and no longer pushes the support leg outer cover to move, and then the rotation of the support leg body stops. At this time, the boss located in the upper cavity is in a vertical state, and the slide rail is perpendicular to the support leg body. The support leg body is in use, and the support leg outer cover adaptively moves outward with the rotation of the support leg body;

[0019] The method for adaptively moving the outer cover in the support leg storage state comprises the following steps:

[0020] Step (A2), in the initial stage, the support leg body is in use perpendicular to the slide rail, the bosses on both sides of the top cover are located in the upper cavity of the longitudinal slide groove, and the bosses in the upper cavity are in a vertical state;

[0021] Step (B2), the first part of the adaptive movement phase, involves rotating the support leg body, causing the support leg body to drive the top cover and the connector to rotate. The top cover carries the boss, causing it to slide within the longitudinal slot. The boss gradually tilts during the sliding process and pulls the support leg outer cover inward.

[0022] In step (C2), the second part of the adaptive movement phase, the outer cover of the support leg moves inward while the transverse chute provided on the outer cover of the support leg slides along the end of the guide rail, and the guide rail gradually approaches the longitudinal chute;

[0023] In step (D2), at the end stage, the top cover rotates with the boss and slides into the lower cavity of the longitudinal slide groove, and no longer pulls the support leg outer cover, and then stops rotating the support leg body. At this time, the boss in the lower cavity is in a horizontal state, and the support leg body is placed inside the slide rail in a storage state, then the support leg outer cover moves inward adaptively with the rotation and storage of the support leg body.

[0024] Compared with the prior art, the present invention is provided with bosses and guide rails, and cooperates with the longitudinal slide grooves and transverse slide grooves provided on the outer cover of the support leg. By rotating the support leg body, the bosses on both sides of the top cover slide inside the longitudinal slide grooves and push the outer cover of the support leg to move. The outer cover of the support leg is limited by the guide rails on the top of the connecting plate, so that the outer cover of the support leg can be moved out when used as the support leg body rotates, and can be stored together with the support leg body when it is stored as the support leg body rotates, thereby reducing the space occupied by the child seat when the support leg body is stored, and facilitating the use of the child seat.
