[0091] Figure 11 is a three-dimensional diagram of a child safety seat 1 according to the present disclosure. According to the present disclosure, the child safety seat 1 includes a seat body 100 and a base 200 connected to the seat body 100. The seat body 100 and the base 200 can be detachably connected or fixedly connected. The seat body 100 can rotate around the body of the base 200 and can slide relative to the base 200 to adjust the angle of the child when sitting on the seat body 100.

[0092] The seat body 100 includes a seat 110, side wings 120, a backrest 130 and a headrest 140. The side wings 120 are arranged on both sides of the seat body 100 to protect the child from the side. As shown in the figure, the side wings 120 can be integrally extended from the headrest 140 through the backrest 130 to the seat 110, and the side wings 120 can also be arranged in sections on both sides of the headrest 140, the backrest 130 and the seat 110. According to this embodiment, a cover plate 150 is arranged on the lower side of the seat body 100. The cover plate 150 has openings for ventilation, for example, and is used to cover the molded parts or components arranged in the seat 110 and / or the side wings 120 and / or the backrest 130.

[0093] The base 200 includes a base body 210, a rotating part 220, a leg 230 and a vehicle seat connector 240. The base body 210 is used to be placed on a vehicle seat and detachably fixed to the vehicle seat through the vehicle seat connector 240. According to the present embodiment, the base 200 includes, for example, a retractable leg 230, which contacts the vehicle floor and can effectively ensure the stability of the child safety seat. In this example, the leg 230 is fixed to the front side below the base body 210, and the lower end of the leg 230 contacts the vehicle floor, so that the child safety seat can remain stable. According to the present embodiment, the rear part of the base body 210 is designed to be higher than the front part, so that the upper side of the base 200 is ramp-shaped to adapt to the shape of the seat 110 or the backrest 130 of the seat body 1.

[0094] According to the present disclosure, a rotating portion 220 for connecting the seat body 100 is provided on the upper side of the base body 210. The rotating portion 220 is provided in an opening in the middle of the base 200 and can rotate relative to the base body 210. For example, it is circular and connected to the seat body 100, so that the seat body 100 can rotate relative to the base body 210 through the rotating portion 220 to Figure 1The seat body 100 is rotated from the first rotation position of the base body 210, that is, the direction in which the seat body 100 is consistent with the direction of the vehicle seat, to the lateral second rotation position (for example, the lateral position in which the seat body 100 is perpendicular to the base 200), or further rotated to the third rotation position in which the seat body 100 is opposite to the direction of the vehicle seat. In addition, the seat body 100 can be rotated relative to the base body 210 through the rotating portion 220 to rotate from the third rotation position to the second rotation position, or further rotated to the first rotation position.

[0095] from Figure 1 It can also be seen that a limiting protrusion 113 is provided on the lower side of the seat body 100, and correspondingly, a first limiting enclosure 211 is provided at the front of the base body 210 and a second limiting enclosure 212 is provided at the rear of the base body 210 around the rotating portion 220. When the seat body 100 is not rotated to the second lateral rotation position, the first limiting enclosure 211 and the second limiting enclosure 212 can prevent the seat body 100 from being excessively pulled out when adjusting the tilt angle relative to the base 200.

[0096] Figure 2 is a perspective view of a child safety seat 1 according to the present disclosure, wherein a seat body 100 and a base 200 are separated.

[0097] according to Figure 2 It can be seen that the limiting protrusion 113 is arranged on the lower side of the seat body 100. The limiting protrusion 113 is at the front end of the lower side of the seat body 100. According to the present disclosure, the limiting protrusion 113 and the cover plate 150 are integrally arranged on the lower side of the seat body 100. The shape of the limiting protrusion 113 is preferably a triangle.

[0098] According to this embodiment, see Figure 2 The base 200 has a ramp-shaped upper side surface, which is inclined from the rear to the front of the base 200 in a manner of decreasing height, thereby making the design of the seat body 100 more flexible and making the overall appearance of the child safety seat 1 more beautiful.

[0099] According to this embodiment, a saddle-shaped limiting support portion 224 is provided on the rotating portion 220 for clamping the seat body 100. The rear portion of the limiting support portion 224 can be designed to be higher than the front portion so as to better cooperate with the corresponding engaging device on the lower side of the seat body 100. The upper side of the limiting support portion 224 is provided with a receiving portion 222 and a pivotable engaging hook 221 to accommodate and clamp the engaging device on the lower side of the seat body 100 (front and rear clamping rods 350, see Figure 3) and fix the seat body 100 to the base 200. On the outer side of the limiting support portion 224, an avoidance groove 223 is provided on the rotating portion 220. The avoidance groove 223 is, for example, a long strip, and is used to avoid the limiting protrusion 113 when the seat body 100 moves relative to the rotating portion 220 to adjust the tilt angle or slide out / backward. According to one embodiment, the avoidance groove 223 can be an arc-shaped groove to adapt to the arc-shaped movement of the limiting protrusion 113.

[0100] According to this embodiment, the first limiting enclosure 211 and the second limiting enclosure 212 are arc-shaped and are arranged on both sides of the rotating part 220 along the direction of the vehicle seat or the front-to-back direction. When the seat body 100 is in a first rotation position consistent with the direction of the vehicle seat, the first limiting enclosure 211 can prevent the seat body 100 from sliding forward, or when the seat body 100 is in a third rotation position opposite to the direction of the vehicle seat, the second limiting enclosure 212 can prevent the seat body 100 from sliding backward. When the seat body 100 is rotated to a direction transverse to the vehicle seat, due to the gap between the first limiting enclosure 211 and the second limiting enclosure 212, the seat body 100 can be slid and pulled out relative to the base 200, for example, slid and pulled out in the direction of the vehicle door, and optionally the seat body 100 can be partially extended out of the vehicle from the open door position, so that the user can easily take the child out of the child safety seat 1 and avoid the child from colliding with the vehicle frame.

[0101] Figure 3 1 is a perspective view of the seat body 100 from another perspective according to an embodiment of the present disclosure, so as to more clearly show the lower side of the seat body 100. The side wings 120 extend to the seat portion 110, and the cover plate 150 matches the seat portion 110 and the side wings 120 in shape. According to this embodiment, for example, a triangular stopper 113 is provided at a front position on the lower side of the cover plate 150, and advantageously, a stopper 113 is provided on each of the two cover plates 150 on both sides of the seat body 100.

[0102] from Figure 3 It can be seen that the sliding mechanism 300 is arranged in the recessed mounting portion 111 on the lower side of the seat body 100, and the recessed mounting portion 111 has a side wall and a top wall perpendicular to the side wall, and the top wall is formed by the lower side of the seat portion 110.

Figure 8 In the embodiment, the seat body 100 is Figure 7 The first angle position in the diagram is converted to a second angle position which is relatively flat. The second sliding rod 340 fixed on the sliding sheet 310 is at the bottom front end of the second angle slot 321 and is also at a turning point between the second angle slot 321 and the second pull-out slot 322. The turning point is the turning point of the seat body 100 between tilt angle adjustment and sliding pull-out. Continuing to pull the seat body 100 toward the front side of the seat body 100 from the turning point will cause the seat body 100 to slide and be pulled out relative to the base 200 toward the front side of the seat body 100. Figure 8 In the embodiment, the locking mechanism 115 provided on the seat body 100 transitions from the rearmost hole of the angle adjustment hole 324 to the frontmost hole under the operation of the unlocking portion 112 and locks the seat body 100 at the second angle position.

[0122] Fig. 9 2 is a perspective view of a child safety seat 1 according to the present disclosure. The seat body 100 is rotated relative to the base body 210 fixed to the vehicle seat by means of the rotating part 220 to Figure 1 The seat body 100 is rotated from a first rotation position, ie, a direction in which the seat body 100 is consistent with the direction of the vehicle seat, to a second rotation position in a lateral direction perpendicular to the base body 210 .

[0123] from Fig. 9 It can be seen in the figure that the latching rod 350 of the sliding mechanism 300 is latched into the receiving portion 222 of the rotating portion 220 and is fixed.

[0124] Fig.101 is a front view of the child safety seat 1 according to the present disclosure. The seat body 100 is in a second lateral rotation position perpendicular to the base body 210, and the seat body 100 is in a relatively upright first angle position. If the user takes the child out in this state, the child's head may collide with the door frame.

[0125] Fig.11 1 is a front view of the child safety seat 1 according to the present disclosure. The seat body 100 is in a second lateral rotation position perpendicular to the base body 210, and the seat body 100 is pulled out to the left side of the base 200 relative to the base 200, so that the child will not collide with the door frame when being carried out of the vehicle. The limiting protrusion 113 installed on the lower side of the cover plate 150 is free from the limitation of the first limiting enclosure 211 and extends from the base 200.

[0126] Fig.12 is along Fig.11 A cross-sectional view of the child safety seat 1 along the middle section line II-II. The first angled slot 311 and the first pull-out slot 312 provided in the sliding plate 310 and the second angled slot 321 and the second pull-out slot 322 provided in the fixing plate 320 are arranged in a mirror image. Fig.11 and Fig.12 In the embodiment, the seat body 100 is pulled out toward the left side of the base 200 relative to the base 200 until the first sliding rod 330 is at the rearmost end of the first pull-out groove 312, and the second sliding rod 340 fixed in the sliding sheet 310 is at the frontmost end of the second pull-out groove 322. The seat body 100 is pulled out to the farthest position relative to the base 200, and the limiting protrusion 113 is not restricted by the first limiting enclosure 211 or the second limiting enclosure 212.

[0127] According to one embodiment, the sliding mechanism 300 includes a sliding frame 310, a fixed frame 320, a sliding groove provided on the fixed frame 320 (for example, a second angle sliding groove 321 and a second pull-out sliding groove 322 provided on the fixed frame 320), and a sliding rod (for example, a second sliding rod 340) fixed on the sliding frame 310, the second sliding rod 340 on the sliding frame 310 extends into the sliding groove on the fixed frame 320 and slides therein, and the sliding mechanism 300 of the embodiment may not include the first sliding rod 330 and the first angle sliding groove 311 and the first pull-out sliding groove 312. By providing a section of angle sliding groove and a section of pull-out sliding groove that are interconnected and angled with each other on one of the sliding frame 310 and the fixed frame 320, the sliding rod on the other of the sliding frame 310 and the fixed frame 320 can slide therein, thereby adjusting the tilt angle of the seat body 100 and realizing the sliding pull-out of the seat body 100. Specifically, when adjusting the inclination angle of the seat body 110, the sliding frame 310 slides relative to the fixed frame 320, and the sliding frame 310 can adjust the inclination angle of the seat body 110 along the path provided by the angle slide groove. When the seat body 100 is in a lateral rotation position, and when the seat body 100 is converted from a relatively upright first angle position to a relatively flat second angle position, the seat body 100 in the relatively flat second angle position is continuously pulled toward the front side of the seat body 100, and the sliding rod will enter the pull-out slide groove and slide therein, and the sliding frame 310 will then slide relative to the fixed frame 320 along the translation path provided by the pull-out slide groove, so that the seat body 100 is translated, slid and pulled out relative to the base 200, so as to adjust the horizontal position of the seat body 100 relative to the base 200.

[0128] According to one embodiment (for example Fig.13), the angle slot and the pull-out slot are, for example, a second angle slot 321 and a second pull-out slot 322 provided on the fixed frame 320, and the pull-out slot 322 may be arc-shaped, so that when the horizontal position of the seat body 100 relative to the base 200 is adjusted, the tilt angle of the seat body 100 relative to the base 200 is also changed. For example, when the seat body 100 is in a relatively upright first angle position, the tilt angle of the seat body 110 is adjusted, and the sliding frame 310 will slide relative to the fixed frame 320, and the sliding frame 310 can adjust the tilt angle of the seat body 110 along the path provided by the angle slot 321, so that the seat body 110 is adjusted to a relatively flat second angle position. When the seat body 100 is in a lateral rotation position, and when the seat body 100 is converted from a more upright first angle position to a more lying second angle position, the seat body 100 continues to be pulled toward the front side of the seat body 100, and the sliding rod will enter the arc-shaped pull-out slot 322 and slide therein, and the sliding frame 310 will then slide relative to the fixed frame 320 along the arc-shaped sliding path provided by the pull-out slot 322, which will cause the seat body 100 to slide and be pulled out relative to the base 200, and then when the horizontal position of the seat body 100 relative to the base 200 is adjusted, the inclination angle of the seat body 100 relative to the base 200 will also change.

[0129] According to one embodiment, a section of an angled slide groove and a section of a pull-out slide groove that are connected to each other and are at an angle are provided on one of the sliding frame 310 and the fixed frame 320, so that the sliding rod on the other of the sliding frame 310 and the fixed frame 320 can slide therein. The angled slide groove and the pull-out slide groove are, for example, a second angled slide groove 321 and a second pull-out slide groove 322 (for example, Fig.14), the pull-out slide groove 322 further includes an angled first pull-out section 322a and a second pull-out section 322b, so that the inclination angle of the seat body 100 can be further adjusted after the seat body 100 is slid and pulled out. Specifically, when adjusting the inclination angle of the seat body 110, the sliding frame 310 slides relative to the fixed frame 320, and the sliding frame 310 can adjust the inclination angle of the seat body 110 along the path provided by the angle slide groove 321. When the seat body 100 is in a lateral rotation position, and when the seat body 100 is converted from a relatively upright first angle position to a relatively flat second angle position, the seat body 100 in the relatively flat second angle position is continuously pulled forward of the seat body 100, and the sliding rod enters the first pull-out section 322a of the pull-out slide groove 322 and slides therein, and the sliding frame 310 then slides relative to the fixed frame 320 along the translation path provided by the first pull-out section 322a of the pull-out slide groove 322, so that the seat body 100 is pulled out with translational sliding relative to the base 200 to adjust the horizontal position of the seat body 100 relative to the base 200. When the seat body 100 is in the pulled-out horizontal position, the seat body 100 is continuously pulled forward of the seat body 100, and the sliding rod enters the second pull-out section 322b of the pull-out slide groove 322 and slides therein, and the sliding frame 310 can adjust the inclination angle of the seat body 110 along the path provided by the second pull-out section 322b.

[0130] According to one embodiment (for example Figure 4 , Figure 7 , Figure 8 ), the sliding mechanism 300 includes a first sliding member (e.g., a first sliding rod 330) and a first sliding groove 31, one of the first sliding member 330 and the first sliding groove 31 is disposed on the seat body 100, and the other of the first sliding member 330 and the first sliding groove 31 is disposed on the fixing frame 310, and the seat body 100 is mounted on the base 200 via the fixing frame 310. The first sliding member 330 is configured to move relative to the first sliding groove 31 along the first sliding groove 31. The first sliding groove 31 includes a first angle sliding groove 311 and a first pull-out sliding groove 312 connected to and angled with the first angle sliding groove 311, wherein the first pull-out sliding groove 312 extends along the longitudinal direction of the seat body 100. The center line of the front side and the rear side of the seat body 100 is arranged in the longitudinal direction of the seat body 100. The front side of the seat body 100 is the foot end 101 of the seat body 100, and the rear side of the seat body 100 is the head end 102 of the seat body 100.

[0131] According to one embodiment, the first angle sliding groove 311 and the first pull-out sliding groove 312 are arranged one in front of the other in the longitudinal direction of the seat body 100 .

[0132] According to one embodiment, the sliding mechanism 300 further includes a second sliding member (e.g., a second sliding rod 340) and a second sliding groove 32, one of the second sliding member 340 and the second sliding groove 32 is disposed on the seat body 100, and the other of the second sliding member 340 and the second sliding groove 32 is disposed on the fixing frame 310; and one of the first sliding member 330 and the second sliding member 340 is disposed on the seat body 100, and the other of the first sliding member 330 and the second sliding member 340 is disposed on the fixing frame 310. The second sliding member 340 is configured to move relative to the second sliding groove 32 along the second sliding groove 32. The second sliding groove 32 includes a second angled sliding groove 321 and a second pull-out sliding groove 322 that is connected to and angled with the second angled sliding groove 321, wherein the second pull-out sliding groove 322 extends along the longitudinal direction of the seat body 100.

[0133] According to one embodiment, the second angle sliding groove 321 and the second pull-out sliding groove 322 are arranged one in front of the other in the longitudinal direction of the seat body 100 .

[0134] According to one embodiment, the first sliding member 330 and the first sliding groove 31 of the sliding mechanism 300 are located at the front portion of the sliding mechanism 300 .

[0135] According to one embodiment, the second sliding member 340 and the second sliding groove 32 of the sliding mechanism 300 are located at the rear portion of the sliding mechanism 300 .

[0136] According to one embodiment, the first angled slot 311 is closer to the front side of the seat body 100 than the first pull-out slot 312 , and the second angled slot 321 is closer to the rear side of the seat body 100 than the second pull-out slot 322 .

[0137] According to one embodiment, the sliding mechanism 300 further includes a limiting protrusion 113 arranged on the seat body 100, and the limiting protrusion 113 cooperates with the limiting enclosures 211 and 212 on the base 200, so that when the seat body 100 is in the same direction or opposite to the direction of the vehicle seat, it can directly or indirectly block the first sliding member 330 from entering the first pull-out groove 312, or directly or indirectly block the second sliding member 340 from entering the second pull-out groove 322.

[0138] According to one embodiment, the limiting enclosures 211 and 212 on the base body 210 are adjacent to the periphery of the rotating portion 220 .

[0139] According to the seat sliding mechanism 300 disclosed in the present invention, a horizontal sliding section and a limiting structure are added to the angle sliding groove, thereby solving the problem of inconvenience in carrying a child in or out of the existing child safety seat.

[0140] In the present disclosure, by rotating the seat body 100 to the side, the seat body 100 can be further slid and pulled out, so that the seat body 100 is closer to the door frame or even pulled out of the door frame, which makes it easier for adults to carry children in or out, and improves the operating experience and satisfaction of the child safety seat 1. Specifically, the front and rear slides are arranged in two sections, namely, an angle slide and a pull-out slide. The angle slide is used to adjust the tilt angle of the seat body 100, and the pull-out slide is used to pull the seat body 100 further out, so that the seat body 100 is closer to the door. This method has a simple structure and is easy to implement. In addition, by providing a limiting protrusion 113 on the seat body 100 and providing front and rear limiting enclosures on the base 200 that cooperate with the limiting protrusion 113, the front and rear limiting enclosures are arranged front and back along the base 200. The directions are symmetrically arranged, so that when the child safety seat 1 is in the forward or rearward state, under the action of the limiting protrusion 113 and the limiting enclosure, the seat body 100 can only adjust the tilt angle and cannot be further slid and pulled out. When the seat body 100 is rotated to the side, the limiting protrusion 113 avoids the limiting enclosure. In this way, by pulling the seat body 100, the seat body 100 can be further slid and pulled out along the pull-out groove, so that the seat body 100 is closer to the vehicle door, making it convenient to carry the child in or out.

[0141] Since the present disclosure can be embodied in a variety of forms without departing from the spirit and substance of the present disclosure, it should be understood that the above-mentioned embodiments are not limited to any of the foregoing details, but should be interpreted in the broadest sense within the scope defined by the claims, and therefore all changes that fall within the scope of the claims or their equivalents should be covered by the claims.
