[0002] Child seats are devices designed for children of different weights and installed in cars to improve passenger safety. They are suitable for children from birth to 14 years old. Child seats are usually installed directly in the rear seat of the vehicle to replace the vehicle's own seat. Children in child seats usually face away from the vehicle, so that their faces will not hit the seats in front of them when the vehicle brakes. In most existing child seats, the body cushion is fixedly installed on the seat, while the headrest is adjustable, changing height as the baby grows before being secured. Therefore, both the headrest and body cushion are essentially fixed to the seat. During driving, due to road conditions, braking and deceleration are frequent. The fixed headrest and body cushion design in most child seats can easily cause the child to be jolted awake or uncomfortable during deceleration due to their own inertia, leading to crying.

[0017] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Please see Figure 1-10 A plug-in infant car seat includes a child seat body 1 and an adjustment plate 3 slidably disposed thereon, and further includes: First movable support plate 51 and second movable support plate 52; The inner bottom wall of the child seat body 1 is provided with an arc-shaped groove 1.1, and the first movable support plate 51 and the second movable support plate 52 are both slidably installed in the groove 1.1; A connecting rod 512 is fixedly installed at one end of the first movable support plate 51 and the second movable support plate 52 that are close to each other, and an extension plate 57 is fixedly installed at one end of the two connecting rods 512 that are close to each other. An elastic band 58 is connected between the two extension plates 57, and a non-Newtonian fluid is filled between the two extension plates 57. A protrusion 31 is fixedly installed on the adjusting plate 3, and a slider 52.1 is slidably installed inside the protrusion 31. The slider 52.1 is fixedly connected to the second movable bearing plate 52. The first movable support plate 51 is used to install the body cushion, while the second movable support plate 52 is used to install the headrest. In most existing child seats, the body cushion is fixedly installed on the child seat, while the headrest is adjustable to adjust its height as the baby grows. After adjustment, it is fixed. Therefore, the headrest and body cushion are basically fixed to the child seat. During driving, due to the complexity of the road, braking and deceleration are frequent. The fixed headrest and body cushion used in most child seats can easily cause the child to be startled or uncomfortable and cry due to the impact of their own inertia when decelerating. Therefore, in this application, the first movable support plate 51 and the second movable support plate 52 make both the body cushion and the headrest movable. The headrest is first installed on the second movable support plate 52. When adjusting, the height is adjusted by adjusting the plate 3, which drives the second movable support plate 52 to adjust the height of the headrest. However, after the headrest height is adjusted, the headrest and the second movable support plate 52 can still move. First refer to Figure 3 With the headrest on the left and the body cushion on the right, and the headrest facing the front of the vehicle after the child seat is installed, if the vehicle suddenly decelerates during travel, the child will move to the left due to inertia. At this time, the first movable support plate 51 and the second movable support plate 52 will slide to the left within the slide groove 1.1. Since the slide groove 1.1 is arc-shaped and the second movable support plate 52 is located at the bottom of the arc, the height of the first movable support plate 51 and the second movable support plate 52 will increase as they move to the left due to inertia. The kinetic energy generated by inertia will be converted into gravitational potential energy. During this process, the leftward movement speed of the first movable support plate 51 and the second movable support plate 52 will decrease, thereby achieving deceleration and reducing the impact force between the child and the child seat caused by inertia during vehicle deceleration. The non-Newtonian fluid between the connecting rod 512 between the first movable support plate 51 and the second movable support plate, and between the extension plate 57, allows the first movable support plate 51 to move back and forth slightly when the vehicle is traveling at low speeds due to minor acceleration and deceleration. At this time, the first movable support plate 51 sways with minimal amplitude and force. The non-Newtonian fluid remains in a fluid state when compressed, thus not affecting the slight swaying of the first movable support plate 51. This allows the first movable support plate 51 to rock a child like a rocking chair according to the vehicle speed, providing better rest. However, when the vehicle suddenly... However, when braking and decelerating, the force exerted on the non-Newtonian fluid by the connecting rod 512 pushed by the first movable support plate 51 increases. At this time, the non-Newtonian fluid will be solid. The first movable support plate 51 will push the connecting rod 512 and the extension plate 57 on it to push the second movable support plate 52 through the non-Newtonian fluid. This allows the first movable support plate 51 and the second movable support plate 52 to slide as simultaneously as possible during sudden braking, thereby maintaining a large-scale synchronous movement between the body pad and the head pad, so that the child can move synchronously with the body pad and the head pad. The second movable support plate 52 is slidably mounted on the protrusion 31 via a slider 52.1 and is always located on the bottom side of the protrusion 31 under the action of gravity. When the position of the sliding adjustment plate 3 is adjusted, the adjustment plate 3 will drive the protrusion 31 to rise. At this time, the protrusion 31 will drive the second movable support plate 52 to move upward via the slider 52.1. The second movable support plate 52 moves upward within the slide groove 1.1. The cooperation between the protrusion 31 and the slider 52.1 only restricts the downward movement of the second movable support plate 52 and facilitates the second movable support plate 52 to slide upward with the first movable support plate 51 under the push of the connecting rod 512. The non-Newtonian fluid connection between the extension plates 57 allows the connecting rod 512 on the second movable support plate 52 to slide freely and adjust its position, while also achieving a tight connection. The child seat body 1 is equipped with a locking mechanism 4, which is used to connect with the vehicle seat. This is an existing mature connection technology and will not be described in detail here.

[0019] In another embodiment of the present invention, the expansion plate 57 is conical.

[0020] In another embodiment of the present invention: a side plate 53 is fixedly installed on the side wall of the first movable support plate 51, a restraint strap 54 is fixedly installed on the side plate 53, and a buckle 55 is fixedly installed on the other end of the restraint strap 54; A connecting tube 59 is fixedly installed on the elastic band 58. An inner tube 510 is provided inside the restraint band 54. One end of the inner tube 510 is connected to the connecting tube 59, and the other end of the inner tube 510 is fixedly connected to the restraint tube 511. A comforting plate 56 is fixedly installed at the end of the restraint tube 511 away from the inner tube 510, and the comforting plate 56 is rotatably installed on the restraint band 54. When a child is placed on the body pad of the first movable support plate 51, the restraint strap 54 is pulled to restrain the child's body. A buckle is provided on the other side of the first movable support plate 51. The buckle and latch 55 work together, and the locking method is the existing seat belt locking structure, which will not be described in detail here. After the child is restrained, as the vehicle starts and accelerates or decelerates, due to the slow change in speed, the non-Newtonian fluid exhibits liquid properties. The restraint tube 511 is connected to the inner tube 510, connecting tube 59, and elastic band 58. Simultaneously, the restraint tube 511 and the inner tube... Both 510 and the connecting tube 59 are filled with non-Newtonian fluid. In a slow state, as the first movable support plate 51 sways back and forth, the connecting rod 512 on the first movable support plate 51 will drive the extension plate 57 on it to squeeze the non-Newtonian fluid between it and the elastic band 58. At this time, the non-Newtonian fluid with the liquid properties will be squeezed into the connecting tube 59, the inner tube 510 and the binding tube 511. At this time, the liquid in the binding tube 511 increases and thus extends, so that the comforting board 56 drops, thereby patting the child's chest area, thus achieving the effect of parents patting and comforting, making it easier for the child to fall asleep and rest.

[0021] In another embodiment of the present invention: a cotton pad is provided at the bottom end of the comforting board 56; The soft cotton padding enhances the soothing effect of the comfort board 56. The comfort board 56 can be wrapped with a cloth strip and then sewn onto the restraint strap 54 to achieve a rotating installation on the restraint strap 54. In addition, the comfort board 56 is relatively large and is located above the child's chest. When there is a flying object in the rear seat during sudden braking, the comfort board 56 can provide a certain degree of blocking and protection.

[0022] In another embodiment of the present invention: a corrugated section is provided on the binding tube 511; The corrugated section on the restraint tube 511 allows the soothing plate 56 to descend when excessive non-Newtonian fluid flows into the restraint tube 511. When the extension plates 57 between the first movable support plate 51 and the second movable support plate 52 move away from each other, the gap between the two extension plates 57 increases, which generates negative pressure and draws in the non-Newtonian fluid from the inner tube 510, the connecting tube 59 and the restraint tube 511. At this time, the non-Newtonian fluid in the restraint tube 511 flows back, which shortens the restraint tube 511 and pulls back the soothing plate 56, so that the soothing plate 56 will slap slightly as the vehicle accelerates or decelerates.

[0023] In another embodiment of the present invention: a handle 2 is rotatably mounted on the child seat body 1, and a pressing plate 61 is slidably mounted on the handle 2; An outer ring 63 is fixedly installed on the side wall of the child seat body 1, and a handle 2 is rotatably installed on the outer ring 63. An inner ring 64 is fixedly installed on the inner wall of the outer ring 63, and several slots 64.1 are opened on the inner ring 64. A locking block 62 is fixedly installed on the pressing plate 61, and a return spring 65 is fixedly installed between the pressing plate 61 and the inner wall of the handle 2. By pressing the inward pressing plate 61, the locking block 62 can be moved out of the locking slot 64.1. At this time, the handle 2 can be rotated. When it is necessary to take the child seat out, the handle 2 can be rotated to the top, and it can be carried like a carrier. When installed in the car, the locking mechanism 4 makes the child seat body 1 installed on the seat. At the same time, the handle 2 can be rotated to the bottom of the child seat body 1. At this time, the handle 2 can contact the bottom of the car to support the part of the child seat body 1 that extends from the vehicle seat, so as to maintain the stability of the child seat.

[0024] In another embodiment of the present invention: a locking block 7 is rotatably mounted on the back of the adjustment plate 3, and a plurality of adjustment holes 1.2 that cooperate with the locking block 7 are provided on the back of the child seat body 1; The locking block 7 is equipped with a hook. When the adjusting plate 3 needs to be adjusted, the locking block 7 is rotated outward. At this time, the hook will move out of the adjusting hole 1.2. After the adjusting plate 3 is moved to the specified height, the hook on the locking block 7 is rotated back into the adjusting hole 1.2. At this time, the hook will be hooked in the adjusting hole 1.2, thereby restricting the downward movement of the adjusting plate 3.

[0025] In another embodiment of the present invention: a through hole 2.1 is provided on the handle 2, and the pressing plate 61 is slidably installed in the through hole 2.1.

[0026] In another embodiment of the present invention: both the first movable support plate 51 and the second movable support plate 52 are concave; The first movable support plate 51 and the second movable support plate 52 are designed in a concave shape to facilitate installation in the side grooves 1.1 on the inner wall of the child seat.

[0027] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
