Description

Technical Field

[0001] The present application relates to the technical field of child safety seats, and in particular to a support leg sensing base structure. Background Art

[0002] A child safety seat is designed for children of different weights (or ages) and effectively improves their safety while riding in a car by restraining them. The main structure of a child seat typically includes a base, a backrest, and support legs. The backrest is mounted to the upper end of the base, and the upper ends of the support legs are mounted to one side of the lower end of the base. When the child safety seat is installed in a car, the lower ends of the support legs rest on the car floor, supporting the child safety seat and improving its stability. In the prior art, to facilitate user identification of whether the support legs are properly contacting the car floor, child safety seats are typically equipped with red and green markings at the bottom of the support legs. Specifically, during the installation of a child safety seat, if the red and green markings indicate red, it indicates that the bottom of the support legs are not fully in contact with the car floor. In this case, it is generally necessary to adjust the installation position of the child safety seat or adjust the length of the support legs until the red and green markings indicate green, indicating that the support legs are fully in contact with the car floor. However, the drawback of the above-mentioned prior art is that, since the red and green identification pieces are located at the bottom of the support legs, when installing the child safety seat in the car, the user needs to bend over or lower his head to observe the color changes of the red and green identification pieces located at the bottom of the support legs, and due to the limited space in the car, it is very inconvenient for the user to operate. Utility Model Content

[0003] The purpose of the utility model is to provide a support leg sensing base structure in view of the defects and shortcomings of the existing technology.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The base body is fixedly arranged at the lower end of the supporting leg, and the bottom pad is movably arranged at the bottom of the base body. The bottom pad is fixedly connected to the identification member, and also includes a metal spring corresponding to the bottom pad. The metal spring is arranged between the bottom pad and the base body, and when the bottom pad is subjected to external force and moves upward relative to the base body, the metal spring is squeezed by the base body or the bottom pad to deform and produce a prompt sound.

[0006] Preferably, the identification member is movably arranged on the upper end of the base body and is sleeved on the circumference of the support leg.

[0007] Preferably, a driving member is provided on the upper side wall of the base pad, the side wall of the metal spring has a groove, and the driving member includes a push rod and a circular ring, the push rod is located in the middle of the circular ring, and when the outer end of the circular ring abuts against the side wall of the metal spring, the outer end of the push rod is located in the groove.

[0008] Preferably, the metal spring sheet enables the bottom pad to always have a downward movement tendency relative to the base body.

[0009] Preferably, the metal spring piece consists of a mounting piece and a bending piece, the mounting piece is mounted on the side wall of the base pad, and one end of the bending piece is arranged on one end of the mounting piece and is inclined.

[0010] Preferably, the base body has a sliding groove at one end close to the bottom pad, and the bottom pad is inserted and slidably moved in the sliding groove.

[0011] Preferably, one end of the base body has a placement groove for placing the identification member, and two through rods are provided on one side of the identification member. One end of the through rod passes through the bottom of the placement groove and into the sliding groove. Two fixing screws are provided on the outside of the base pad, and the fixing screws install the base pad on one end of the through rod.

[0012] Preferably, the mounting piece is fixedly mounted on the peripheral side of the through rod, and the bending piece is provided with a U-shaped groove at one end away from the mounting piece, and the U-shaped groove allows the other through rod to slide.

[0013] Preferably, an anti-slip pad is provided on the outer side of the base pad.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] 1. After the child seat is installed, the inner tube of the support leg slides inside the outer tube of the support leg, allowing the base to move downward until the base pad contacts the bottom of the car interior. The drive element then interacts with the groove of the metal shrapnel, causing the metal shrapnel to make a sound, indicating that the base at the lower end of the support leg is stably placed on the bottom of the car interior. During this process, the driver does not need to bend down to observe the changes in the identification parts, which improves the convenience of child seat installation.

[0016] 2. The metal shrapnel consists of a mounting plate and a bending plate. The mounting plate is set horizontally, and the bending plate is set at an angle. The elastic action of the metal shrapnel prevents the groove from contacting the driving part between the bottom pad and the base body;

[0017] 3. The lower end surface of the bottom pad is installed with an anti-skid pad, which can increase the friction between the bottom pad and the bottom of the car, thereby improving the stability of the child seat. BRIEF DESCRIPTION OF THE DRAWINGS
