Detailed Description

The following detailed description of the preferred embodiments of the invention, taken in conjunction with the accompanying drawings, enables the advantages and features of the invention to be more readily understood by those skilled in the art.

Referring to fig. 1 and 2, a child car seat includes a base 100 and a seat body 200, wherein the seat body 200 is relatively rotatably disposed on the base 100 about a first rotation center line X extending along a height direction of the seat body 200. Thus, the seat body 200 can rotate 360 degrees around the first rotation center line X, so that the child car seat has a forward use state and a reverse use state. When the child car safety seat is in the forward use state shown in fig. 1, the seat body 200 and the base 100 are oriented in the same direction, so that a child can sit in the car driving direction, and the child car safety seat is suitable for older children (generally, the child needs to be older than 3 years); when the child car seat is in the reverse use state shown in fig. 2, the seat body 200 and the base 100 face opposite directions, and a child sits on the backrest of the car seat, so that the child car seat is suitable for a younger child (less than 3 years old), the body of the child is completely wrapped between the seat body 200 and the base 100, and the safety performance is higher.

In addition, when the seat body 200 rotates to the middle position of the forward use state and the reverse use state, the seat body 200 faces the left side and the right side of the automobile seat, and at the moment, parents can stand outside the automobile to hold children in or out of the seat body 200, which is very convenient.

Referring to fig. 3-15, in order to guide parents to correctly use the positive and negative reversing function of the child car seat and prevent potential safety hazards caused by misuse, the child car seat further comprises a reversing guide mechanism. Specifically, the reversing guide mechanism includes a guide groove 1 and a guide 2. Wherein, the guide groove 1 is opened on the base 100, and the guide 2 is arranged on the seat body 200 in a relatively movable way; of course, in other embodiments, the guide groove 1 may be provided in the seat body 200, and the guide 2 may be provided in the base 100 so as to be movable relative thereto. In this embodiment, the guide member 2 has a protruding portion 21 protruding from the seat body 200, so that the protruding portion 21 can be inserted into the guide groove 1 in a relatively sliding manner, and provides guidance and limit for the rotation and direction change of the seat body 200.

Referring to fig. 9 and 12, in the present embodiment, the base 100 has a supporting cavity 101 with an upward opening, an inner sidewall of the supporting cavity 101 is located in a virtual arc surface, and the virtual arc surface is a spherical surface with the first rotation center line X as an axis; the bottom surface 201 of the seat body 200 is also located in the virtual arc surface along which the guide 2 is relatively slidably provided on the bottom surface 201, and an extension line of the sliding direction of the guide 2 intersects the first rotation center line X. In this way, in the process that the seat body 200 rotates 360 degrees around the first rotation center line X, the supporting cavity 101 can be always attached and stably supported below the bottom surface 201, and a supporting surface with uniform stress is formed between the base 100 and the seat body 200.

Referring to fig. 12 to 15, the guide groove 1 is disposed in the supporting cavity 101, and the guide groove 1 specifically includes a first guide groove 11, a second guide groove 12, and a reversing groove 13. The first guide groove 11 and the second guide groove 12 extend along the circumferential direction of the base 100, and the first guide groove 11 and the second guide groove 12 are respectively disposed on the front side and the rear side of the first rotation center line X. The reversing slots 13 are divided into two groups which are arranged at the left side and the right side of the first rotation center line X, each group of reversing slots 13 extends along the radial direction of the base 100, and the first guide slot 11 and the second guide slot 12 are communicated through the reversing slots 13 at each of the left side and the right side of the base 100.

In this embodiment, the extending directions of the first guide groove 11 and the second guide groove 12 are respectively semicircular arcs taking the first rotation center line X as the axis, the extending direction of the first guide groove 11 is a first arc 1001, the extending direction of the second guide groove 12 is a second arc 1002, and the radius R1 of the first arc is smaller than the radius R2 of the second arc. Thus, the first guide groove 11 and the second guide groove 12 form two semicircular arc grooves arranged at intervals along the radial direction of the support cavity 101, the first guide groove 11 is positioned at the rear side and is inclined inwards, and the second guide groove 12 is positioned at the front side and is inclined outwards; of course, in other embodiments, the first guide groove 11 may be located at the rear side and be offset outward, and the second guide groove 12 may be located at the front side and be offset inward. In the present embodiment, on each of the left and right sides of the base 100, a radially extending diverting groove 13 is connected between one end of the first guide groove 11 and one end of the second guide groove 12. Specifically, each set of the reversing grooves 13 has a first blocking wall 13a and a second blocking wall 13b, the first blocking wall 13a and the second blocking wall 13b extend along the radial direction of the supporting cavity 101, the first blocking wall 13a is located in the length extending direction of the first guide groove 11, the second blocking wall 13b is located in the length extending direction of the second guide groove 12, the first blocking wall 13a and the second blocking wall 13b are arranged at intervals along the circumferential direction of the base 100, the first blocking wall 13a is located at one side close to the second guide groove 12, the second blocking wall 13b is located at one side close to the first guide groove 11, and the first blocking wall 13a and the second blocking wall 13b are arranged at intervals along the radial direction of the base 100. In fact, the partition passage between the first blocking wall 13a and the second blocking wall 13b forms the diverting groove 13, and forms a zigzag-shaped sliding groove structure among the first guide groove 11, the diverting groove 13 and the second guide groove 12 which are communicated with each other.

Correspondingly, referring to fig. 9 to 11, in the sliding direction of the guide 2, the guide 2 has a first position and a second position on the seat body 200, the first position is located on a side relatively close to the first rotation center line X, the second position is located on a side relatively far from the first rotation center line X, and the reversing guide mechanism further includes a driving component for driving the guide 2 to switch between the first position and the second position.
