Description

Technical Field

[0001] This utility model relates to the field of stroller technology, and more specifically, to a sliding structure for a stroller seat. Background Technology

[0002] A stroller is a tool designed to facilitate outdoor activities for infants. It is one of the most beloved modes of transportation for babies and an essential item for mothers when taking their babies shopping. However, the inventors have discovered that current strollers, when used rear-facing, have a rearward center of gravity, making them prone to tipping over and unstable.

[0003] In view of the aforementioned deficiencies in the sliding structure of stroller seats, and adhering to the spirit of research, innovation, and continuous improvement, the applicant, combined with production practice and using professional and scientific methods, proposes a practical solution and therefore submits this application. Utility Model Content

[0004] The purpose of this invention is to provide a sliding structure for a stroller seat that addresses the current state of technology by enabling the seat to move in tandem with the folding backrest, thereby solving the problem of unstable center of gravity in the stroller frame.

[0005] A sliding structure for a stroller seat includes: a backrest, a seat, armrests, and a stroller base. The seat and backrest are mounted on the stroller base, and the armrests are connected to the connection points of the backrest and the seat at both ends. The seat consists of an upper sliding seat, a mounting base, and a lower fixed seat. The upper sliding seat is mounted on the mounting base and moves back and forth along a slide rail. The mounting base is mounted on the lower fixed seat, which is hinged to a mounting rod on the stroller base. The mounting base has outwardly extending connecting plates on both sides. One end of a connecting arm is hinged to the connecting plate, and the other end of the connecting arm is hinged to the outside of the connecting part at the bottom of the backrest. The connecting part of the backrest is connected to the seat via a pivot.

[0006] Specifically, the upper sliding seat has clearance slots on both sides, and the connecting arm passes through the clearance slots and moves back and forth along the clearance slots.

[0007] Specifically, the upper sliding seat consists of a seat plate and a fixed plate. Two tension plates are provided between the seat plate and the fixed plate. The tension plates move back and forth along the slide rail. A damping element is provided below the tension plates, and a pressure spring is provided below the damping element.

[0008] Specifically, the damping element is installed in the groove of the fixed plate, and the top of the damping element is hemispherical.

[0009] Specifically, the bottom of the stretching plate is provided with several protrusions, which correspond to the slide rails on the fixed plate and move back and forth along the slide rails.

[0010] Specifically, the stretching plate is provided with at least one limiting groove, and a limiting post is provided between the seat plate and the fixing plate, with the limiting post penetrating the limiting groove.

[0011] Specifically, the connecting arm is L-shaped, with one end of the short arm bent inward and hinged to the connecting post of the connecting plate, and the long arm hinged to the connecting part of the backrest.

[0012] The beneficial effects of this utility model are as follows: when folding the backrest, the connecting arm is used to drive the seat to move forward and backward along the slide rail, which can realize the shift of the seat's center of gravity when adjusting the backrest, making the frame more stable, saving folding steps, and making it more convenient and quick.

Detailed Implementation

[0019] The accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0020] Please see Figures 1 to 5As shown, a sliding structure for a stroller seat includes: a backrest, a seat, armrests, and a stroller base. The seat and backrest are mounted on the stroller base, and the armrests are connected to the connection points of the backrest and the seat at both ends. The seat consists of an upper sliding seat, a mounting base, and a lower fixed seat. The upper sliding seat is mounted on the mounting base and moves back and forth along a slide rail. The mounting base is mounted on the lower fixed seat, which is hinged to a mounting rod on the stroller base. Connecting plates extending outwards are provided on both sides of the mounting base. One end of a connecting arm is hinged to the connecting plate, and the other end is hinged to the outside of the connecting part at the bottom of the backrest. The connecting part of the backrest is connected to the seat via a pivot. The connecting arm is L-shaped, with one end of the shorter arm bent inwards and hinged to the connecting post of the connecting plate, and the longer arm hinged to the connecting part of the backrest.

[0021] In the proposed solution, both sides of the sliding seat are provided with clearance grooves, and the connecting arm passes through the clearance grooves and moves back and forth along them. The sliding seat consists of a seat plate and a fixed plate, with two tension plates between them. The tension plates move back and forth along slide tracks, and a damping element is provided below the tension plates, with a pressure spring below the damping element. The damping element is installed in a groove in the fixed plate, and its top is hemispherical. The bottom of the tension plates has several protrusions, which correspond to the slide tracks on the fixed plate and move back and forth along them. The tension plates have at least one limiting slide groove, and a limiting post is provided between the seat plate and the fixed plate, with the limiting post passing through the limiting slide groove.

[0022] Seat sliding procedure: First, press the designated button to release the backrest and seat restrictions. The backrest can fold backward or forward. When folded backward, the sliding seat will move forward along the rail under the action of the connecting arm, putting the seat in a reclining position. The infant's center of gravity will also change accordingly. Therefore, it is necessary to move the seat forward to keep the center of gravity in the seat's support position.

[0023] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
