DETAILED DESCRIPTION

[0024] Reference herein to an embodiment means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. The appearance of such a phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] A vehicle-mounted child safety seat with side protection function, as shown in Figures 1 and 2, includes a seat 1, a seat cushion 2, a back cushion 3, a headrest 4, a side protection mechanism 5 and a limiting mechanism 6. The seat cushion 2 is connected to the top of the seat 1, the back cushion 3 is connected to the front side of the seat 1, the headrest 4 is connected to the front side of the upper part of the seat 1, the side protection mechanism 5 is provided on the seat 1, and the limiting mechanism 6 is provided on the seat 1.

[0026] When the car is driving, children are required to have a special seat 1 to ensure their safety. This seat 1 can provide comprehensive support for the child through the seat cushion 2, back cushion 3, and headrest 4 to improve the child's riding comfort. The side protection mechanism 5 limits the left and right sides of the child to prevent the child from moving violently and causing a rollover and fall. At the same time, the side protection mechanism 5 is restricted by the limiting mechanism 6 to prevent damage to the side protection mechanism 5.

[0027] As shown in Figures 1 to 3, the side protection mechanism 5 includes a first fixed seat 51, a protective plate 52, a torsion spring 53 and a pad 54. Two first fixed seats 51 are connected to the front sides of the left and right parts of the seat 1, which are symmetrical in upper and lower directions. The protective plates 52 are rotatably connected between the first fixed seats 51, two torsion springs 53 are connected between the protective plates 52 and the first fixed seats 51, and the pads 54 are connected to the sides of the protective plates 52 that are close to each other.

[0028] When a child rides in a car, after sitting on the seat 1, the protective plate 52 can be used to protect the child on both sides to prevent the child from tipping over during the process of large-scale left and right shaking. When the child shakes, the corresponding protective plate 52 and the soft cushion will rotate, so that the corresponding torsion spring 53 is deformed under force, thereby offsetting the force generated by the child's shaking, stabilizing the child's body shape, and preventing the child from falling. In summary, the protective plate 52 and the soft cushion are used to limit and protect the left and right sides of the child, preventing the child from tipping over due to shaking, and improving the stability and safety of the child when riding.

[0029] As shown in Figures 1, 2 and 4, the limiting mechanism 6 includes a fixing frame 61, a support rod 62 and a fixing block 63. Two fixing frames 61 that are symmetrical in vertical direction are connected to the left and right sides of the seat 1. The sides of the fixing frames 61 located at the same height that are close to each other are connected to the support rod 62, and the sides of the support rods 62 located at the same height that are close to each other are connected to the fixing block 63.

[0030] As the protective plate 52 is pushed and rotated, adjacent fixing blocks 63 will contact the protective plate 52, thereby supporting the protective plate 52 and preventing damage caused by excessive rotation of the protective plate 52. At the same time, it can also improve the supporting capacity of the protective plate 52 and better protect children.

[0031] As shown in Figures 1, 2 and 5, it also includes an adjustment mechanism 7, which includes a winding wheel 71, a pull rope 72, a gear 73, a wire wheel 74 and a pull rod 75. The rear side of the seat 1 is rotatably connected to two winding wheels 71, and a pull rope 72 is wound around the winding wheels 71. The two winding wheels 71 are connected to gears 73 on the sides close to each other. The two working sides of the seat 1 are rotatably connected to wire wheels 74, and the tension is wound around the corresponding wire wheels 74. The sides of the protective plates 52 that are away from each other are connected to pull rods 75, and the front ends of the pull ropes 72 are connected to the corresponding pull rods 75.

[0032] When a child needs to sit on the seat 1, first one of the winding wheels 71 is rotated so that the pull rope

[0033] 72 are both wound up, and the gear 73 is rotated, thereby causing the two winding wheels 71 to rotate at the same time.

[0034] During the reeling process of 72, the wire pulley 74 will guide the drawstring 72 to prevent the drawstring 72 from getting tangled and knotted in the middle, and at the same time pull the pull rod 75 to move away from each other, thereby achieving the effect of simultaneously deploying the protective plate 52. When the child is ready, the reel 71 is released, and the protective plate 52 is rotated and reset under the action of the torsion spring 53, thereby driving the pull rod 75 to move and reset, and then the drawstring 72 is pulled out. In summary, by rotating the reel 71, the drawstring 72 is reeled, so that the protective plate 52 is quickly pulled open, making it easier for the child to sit on the seat 1.

[0035] As shown in Figures 1, 2 and 6, a buffer mechanism 8 is also included. The buffer mechanism 8 includes an adapter plate 81, a second fixed seat 82 and a slide rod 83. Two adapter plates 81 that are symmetrical in vertical direction are connected to the sides of the protective plate 52 that are away from each other. Two second fixed seats 82 that are symmetrical in vertical direction are connected to the adapter plates 81. The second fixed seats 82 are rotatably connected to the slide rod 83. The slide rod 83 is slidably connected to the adjacent fixed block 63.

[0036] As the protective plate 52 is pushed and rotated, the adapter plate 81 is driven to move, so that the slide bar 83 rotates and slides on the fixed block 63 at the same time, thereby preliminarily restricting the protective plate 52, reducing the flip angle of the protective plate 52, and weakening the force on the protective plate 52.

[0037] As shown in Figures 2 and 5, it also includes a drive component 9. The drive component 9 is connected to the rear side of the seat 1, and the drive component 9 is connected to the upper winding wheel 71. The drive component 9 includes a drive motor and a motor fixing frame. The rear side of the seat 1 is connected to the motor fixing frame by bolts, and the drive motor is connected to the motor fixing frame. The output shaft of the drive motor is connected to the upper winding wheel 71.

[0038] When the winding wheel 71 needs to be rotated, the driving component 9 can be directly started. The driving component 9 drives the winding wheel 71 to rotate automatically, thereby eliminating the need for people to manually rotate the winding wheel 71, thereby improving convenience in use.

[0039] As shown in FIG. 1 and FIG. 6 , a spring 10 is further included, and the spring 10 is connected between the slide rod 83 and the fixing frame 61 .

[0040] As the slide bar 83 slides, the spring 10 is compressed, thereby buffering and weakening the force on the slide bar 83 , thereby achieving the effect of buffering and weakening the force on the protective plate 52 .

[0041] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
