Description

A footrest adjustment mechanism for a child seat Technical Field

[0001] This application relates to the field of infant and toddler products, and more particularly to a footrest adjustment mechanism for a child seat. Background Technology

[0002] A child car seat generally includes a seat, a backrest pivotally connected to the rear of the seat, and a footrest pivotally connected to the seat. To make the seat more convenient to use, the footrest is usually designed to rotate and switch between different angle positions relative to the seat. For example, the footrest can rotate upward relative to the seat to an angle position roughly parallel to the seat, or it can rotate downward relative to the seat to a suitable tilt angle position so that the child's legs can rest naturally when sitting on the seat.

[0003] Traditional child seat footrest adjustment mechanisms typically include two toothed grooves located on opposite sides of the footrest and seat, a gear axially movable between the two grooves, a spring positioned between the gear and the bottom wall of the footrest toothed groove, and a button that can move left and right relative to the seat. One side of the button extends into the toothed groove and abuts against the gear, while the other side is located on the outside of the seat for easy pressing. Under the action of the spring, the gear simultaneously engages with the toothed grooves of both the footrest and the seat, preventing relative rotation between the footrest and the seat, thus locking the footrest at that angle relative to the seat. To adjust the footrest angle relative to the seat, pressing the button pushes the gear into the footrest toothed groove and disengages it from the seat toothed groove. Simultaneously, the footrest is rotated up / down until it reaches the desired angle. Releasing the button then causes the gear, under the action of the spring, to move towards the seat toothed groove and engage with both the footrest and the seat toothed groove again, preventing relative rotation between the footrest and the seat, locking the footrest at another angle relative to the seat, thus adjusting the footrest angle relative to the seat. The aforementioned traditional pedal angle adjustment device makes the pedal angle adjustment operation rather cumbersome. Summary of the Invention

[0004] The purpose of this application is to provide a footrest adjustment mechanism for a child seat, which has a simple structure, is easy to operate, and can quickly adjust the footrest angle.

[0005] The technical solution of this application is: a footrest adjustment mechanism for a child seat, including a seating part and a footrest. The seating part is provided with a base for mounting the footrest. The footrest is rotatably connected to the base through a rotating connecting part. A shift seat that can slide relative to its axial direction is installed in the base, and a reset member is provided between the shift seat and the base. The rotating connecting part has adjusting teeth, and the shift seat has a plurality of tooth grooves arranged at intervals along the circumferential direction for the adjusting teeth to engage. The footrest angle is adjusted by engaging the adjusting teeth with the tooth grooves at different positions.

[0006] As a preferred technical solution, the adjusting tooth is a conical tooth with a high center and low sides, the tooth groove is a conical groove corresponding to the adjusting tooth, and the groove openings of adjacent tooth grooves are smoothly connected.

[0007] As a preferred technical solution, the adjusting tooth protrudes on the side end face of the rotating connection portion near the gear seat, and the tooth groove is formed on the side end face of the gear seat near the rotating connection portion.

[0008] As a preferred technical solution, the adjusting teeth on the rotating connection part are two symmetrically arranged teeth.

[0009] As a preferred technical solution, the mounting groove of the base for mounting the gear seat has several guide ribs arranged on its groove wall, and the outer peripheral wall of the gear seat has several guide grooves that slide in cooperation with the guide ribs; the gear seat achieves relative axial sliding with the base through the sliding cooperation between the guide grooves and the guide ribs.

[0010] As a preferred technical solution, the base is installed on the bottom front side of the seating part.

[0011] As a preferred technical solution, the base, the rotating connection part, the gear seat, and the reset component are all arranged in two symmetrical positions.

[0012] As a preferred technical solution, the reset component is a reset spring, which keeps the gear seat pressed against the corresponding rotating connection part.

The reset member 5 is a reset spring, which presses the end of the gear position seat 4 with the tooth groove 401 against the adjusting tooth 202 of the corresponding rotating connection 201, so that the gear position seat 4 can limit the pedal 2 at different angles and keep it in the corresponding gear position.

[0040] In this embodiment, the adjusting teeth 202 on the rotating connection part 201 are two symmetrically arranged, which simplifies the structure, reduces costs, and ensures the stability of the fitting.

[0041] In this embodiment, the mounting groove 301 of the base 3 for mounting the gear seat 4 is provided with a plurality of guide ribs 302, and the outer peripheral wall of the gear seat 4 is provided with a plurality of guide grooves 402 that slide in cooperation with the guide ribs 302; the gear seat 4 achieves relative axial sliding with the base 3 through the sliding cooperation between the guide grooves 402 and the guide ribs 302.

[0042] In this embodiment, the base 3 is installed on the bottom front side of the seating part 1, and has a fixing part 303 fixedly connected to the seating part 2 and an mounting part 304 rotatably engaged with the rotating connection part 201 of the footrest 2.

[0043] To facilitate assembly and ensure rotational stability between the footrest 2 and the seat 1, in this embodiment, the base 3, the rotating connection part 201, the gear seat 4, and the reset member 5 are all arranged symmetrically on the left and right.

[0044] The foot pedal 2 described in this application can be adjusted by adjusting the tooth 202 and engaging with the tooth groove 401 at different positions when rotating. The structure is simple, the operation is convenient, and the foot pedal angle can be quickly adjusted.
