A foldable child safety seat

Abstract

This utility model relates to the field of child safety seat technology, and provides a foldable child safety seat, including a seat body. A sleeve is fixedly installed on the outer wall of the seat body, and a button is movably connected inside the sleeve. A spring pin is fixedly connected to one side of the button, and a rotating shaft is fixedly installed on the other side of the button. A seat back is installed on the outer wall of the rotating shaft, and a limiting hole is formed inside the seat back. By pressing the button, the spring pin is compressed, causing one end of the spring pin to move out of the limiting hole. Pressing the seat back then allows the seat back to fold and rotate along the seat body, facilitating the folding and storage of the seat body and seat back according to actual usage needs. By pulling the headrest upwards, a movable block slides upwards along a guide groove, allowing the headrest height to be adjusted according to actual usage needs.

Description

Technical Field

[0001] This utility model relates to the field of child safety seat technology, and in particular to a foldable child safety seat. Background Technology

[0002] Child safety seats are a type of "child restraint system for motor vehicles," specifically designed for children of different ages and weights. Installed inside a vehicle, they ensure the safety of children while traveling. A child safety seat consists of a strap assembly or flexible component with safety buckles, adjustment mechanisms, connecting devices, and auxiliary devices, and is secured to the vehicle using a mounting system. In the event of a car collision or sudden deceleration, it reduces the impact force on the child and restricts their body movement, thereby mitigating injury.

[0003] To address this, patent CN215474627U discloses a child safety seat, including a seat body, a seat cushion on the upper surface of the seat body, and a buckle attached to the seat cushion; armrests on both sides of the upper end of the seat body, the armrests being higher than the upper surface of the seat body; and bases integrally formed on both sides of the seat body; a seat belt extends from the rear, passes between the armrests and the bases, lies on the upper surface of the seat body, and secures the seat body; thus, the armrests and the upper surface of the seat body form a safety seat position. This technical solution provides a seat body that, together with the buckle and seat cushion, forms a safety seat position. It lacks a backrest for easy access and can be placed on a car seat and secured directly with a seat belt. The buckle is used to restrain the child and prevent collisions.

[0004] The existing technical solutions mentioned above have the following drawbacks: when in use, it is inconvenient to fold and store the child safety seat according to the actual needs, resulting in a large size of the safety seat, which takes up a lot of space when stored and affects its convenience. Utility Model Content

[0005] The purpose of this invention is to provide a foldable child safety seat to solve the problem that existing child safety seats are inconvenient to fold and store according to actual usage needs.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a foldable child safety seat, including a seat body;

[0007] A sleeve is fixedly installed on the outer wall of the seat body, and a button is movably connected inside the sleeve. A spring pin is fixedly connected to one side of the button, and a rotating shaft is fixedly installed on the other side of the button.

[0008] A seat back is mounted on the outer wall of the rotating shaft, and a limit hole is formed inside the seat back.

[0009] Preferably, the seat body and the seat back form a rotating structure through a pivot, and the seat back is engaged with a spring pin through a limiting hole, which allows the seat back to be flipped and folded along the seat body.

[0010] Preferably, the button and the sleeve form a sliding structure, and the spring pin is movably installed inside the sleeve, allowing the button to slide along the sleeve.

[0011] Preferably, the seat back has a guide groove inside, a movable block is movably connected inside the guide groove, a headrest is fixedly connected to the outer wall of the movable block, a pull groove is opened inside the headrest, and a shoulder strap buckle is fixedly connected to the outer wall of the headrest.

[0012] Preferably, the seat backrest forms a sliding structure with the movable block via a guide groove. The guide groove is symmetrically arranged about the central axis of the seat backrest, allowing the movable block to slide and adjust along the guide groove.

[0013] Preferably, the headrest and the seat back form a sliding structure, and the movable blocks are symmetrically arranged about the central axis of the headrest.

[0014] Preferably, the movable block is movably installed to the seat back by bolts, and the seat back has a slotted design.

[0015] The advantages of the foldable child safety seat provided by this utility model are as follows:

[0016] By setting up the seat body, button, spring pin, seat back and limiting hole, pressing the button will squeeze the spring pin, causing one end of the spring pin to move out of the limiting hole. At this time, pressing the seat back will cause the seat back to flip and fold along the seat body, which can facilitate the folding and storage of the seat body and seat back according to actual use needs, and improve the portability of use.

[0017] Furthermore, the spring pin and the limiting hole work together to limit the position of the seat back after folding.

[0018] By using the seat backrest, guide groove, movable block, headrest, pull groove and shoulder strap buckle, the movable block can slide up along the guide groove by pulling the headrest upward, so that the headrest can slide up along the seat backrest, which can make it easy to adjust the height of the headrest according to actual usage needs.

[0019] Furthermore, the headrest has internal grooves, which improves the ease of pulling it.

[0020] Furthermore, since the shoulder strap buckle adjusts synchronously with the headrest, there is no need to manually re-thread the shoulder strap, ensuring that the shoulder strap height is always in the optimal safe position for the child's shoulders. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 The present invention provides a foldable child safety seat, including a seat body 1.

[0029] Reference Figure 1 , Figure 2 and Figure 4 As shown, a sleeve 2 is fixedly installed on the outer wall of the seat body 1. A button 3 is movably connected inside the sleeve 2. A spring pin 4 is fixedly connected to one side of the button 3. A rotating shaft 5 is fixedly installed on the other side of the button 3. A seat back 6 is installed on the outer wall of the rotating shaft 5. A limiting hole 7 is opened inside the seat back 6. The seat body 1 and the seat back 6 form a rotating structure through the rotating shaft 5. The seat back 6 is engaged with the spring pin 4 through the limiting hole 7. The button 3 and the sleeve 2 form a sliding structure. The spring pin 4 is movably installed inside the sleeve 2.

[0030] By pressing button 3, the button 3 slides along sleeve 2 and squeezes spring pin 4, causing one end of spring pin 4 to move out of limit hole 7. At this time, pressing seat back 6, under the action of pivot 5, can make seat back 6 flip and fold along seat body 1. Releasing button 3 will reset spring pin 4 and automatically lock it.

[0031] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the seat back 6 has a guide groove 8 inside, and a movable block 9 is movably connected inside the guide groove 8. A headrest 10 is fixedly connected to the outer wall of the movable block 9.
