[0088] While this disclosure has been illustrated and described with reference to specific embodiments, it should not be limited to the details shown. In fact, various modifications to these details may be made within the scope of equivalents of the claims without departing from this disclosure.

[0089] The descriptions of directions such as "front", "back", "up" and "down" used in this document are for ease of understanding only. This utility model is not limited to these directions, but can be adjusted according to the actual situation. Although this disclosure has been described with reference to typical embodiments, the terminology used is illustrative and exemplary, and not restrictive.

[0090] According to one embodiment of this disclosure, a child safety seat includes a seat and a base. When it is necessary to carry a child in or out, the seat is rotated to one side of the base body, i.e., the seat faces the vehicle door. The seat body has a front sliding groove, which includes a front angle sliding groove and a front pull-out sliding groove. A fixed seat is provided at the bottom of the seat body, and the seat body slides relative to the fixed seat. The fixed seat has front and rear locking rods connected to the base. The base has a rotating seat with front and rear engaging hooks. The seat is engaged with the front and rear engaging hooks on the rotating seat by the front and rear locking rods, respectively. The fixed seat includes a fixing frame, a bottom cover, and a front sliding rod. The fixing frame further has a rear sliding groove, which includes a rear angle sliding groove and a rear pull-out sliding groove. The front sliding rod is fixed to the fixing frame and slides within the front sliding groove, and the rear sliding rod is fixed to the seat body and slides within the rear sliding groove. Furthermore, the child safety seat includes an operating component and a locking mechanism. The locking mechanism is located on the seat body, and the mounting bracket is provided with an angle adjustment hole that cooperates with the locking mechanism. Pulling the operating component disengages the locking mechanism from the angle adjustment hole, allowing the seat body to slide along the front and rear sliding tracks.

[0091] Figure 1This is a perspective view 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 when the child is sitting in the seat body 100.

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

[0093] The base 200 includes a base body 210, a rotating part 220, a support leg 230, and a vehicle seat connector 240. The base body 210 is placed on a vehicle seat and detachably fixed to the vehicle seat via the vehicle seat connector 240. According to this embodiment, the base 200 includes, for example, a retractable support leg 230 that contacts the vehicle floor, effectively ensuring the stability of the child safety seat. In this example, the support leg 230 is fixed to the front side below the base body 210, with its lower end abutting against the vehicle floor, thereby maintaining the stability of the child safety seat. According to this embodiment, the rear of the base body 210 is designed to be higher than the front, so that the upper side of the base 200 is ramp-shaped to adapt to the shape of the seat portion 110 or the backrest portion 130 of the seat body 1.

[0094] According to this disclosure, a rotating part 220 for connecting the seat body 100 is provided on the upper side of the base body 210. The rotating part 220 is disposed 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 is connected to the seat body 100, so that the seat body 100 can rotate relative to the base body 210 through the rotating part 220, so as to... Figure 1The seat body 100 can rotate relative to the base body 210 from a first rotational position, i.e., in the direction where the seat body 100 is aligned with the vehicle seat direction, to a second rotational position (e.g., a lateral position where the seat body 100 is perpendicular to the base 200), or further to a third rotational position where the seat body 100 is opposite to the vehicle seat direction. Furthermore, the seat body 100 can rotate relative to the base body 210 via the rotating part 220 to rotate from the third rotational position to the second rotational position, or further to the first rotational 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. Correspondingly, around the rotating part 220, a first limiting barrier 211 is provided at the front of the base body 210 and a second limiting barrier 212 is provided at the rear of the base body 210. When the seat body 100 is not rotated to the second lateral rotation position, the first limiting barrier 211 and the second limiting barrier 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 The image is a perspective view of the child safety seat 1 disclosed herein, wherein the seat body 100 and the base 200 are separated.

[0097] according to Figure 2 As can be seen, a limiting protrusion 113 is provided on the lower side of the seat body 100. The limiting protrusion 113 is located at the front end of the lower side of the seat body 100. According to this disclosure, the limiting protrusion 113 is integrated with the cover plate 150 on the lower side of the seat body 100, and the shape of the limiting protrusion 113 is preferably triangular.

[0098] According to this embodiment, see Figure 2 The base 200 has a ramp-shaped upper side that slopes from the rear to the front of the base 200 in a way that lowers the height, which makes the design of the seat body 100 more flexible and the overall shape of the child safety seat 1 more aesthetically pleasing.

[0099] According to this embodiment, a saddle-shaped limiting support portion 224 is provided on the rotating part 220 for engaging the seat body 100. The rear part of the limiting support portion 224 can be designed to be higher than the front part so as to better cooperate with the corresponding engaging device on the lower side of the seat body 100. A receiving part 222 and a pivotable engaging hook 221 are provided on the upper side of the limiting support portion 224 to receive and engage the engaging device (front and rear locking rods 350, see below) on the lower side of the seat body 100. Figure 3The seat body 100 is then fixed to the base 200. On the outer side of the limiting support portion 224, a clearance groove 223 is provided on the rotating portion 220. The clearance groove 223 is, for example, elongated, 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 slides out / backward. According to one embodiment, the clearance groove 223 can be an arc-shaped groove to accommodate the arc-shaped movement of the limiting protrusion 113.

[0100] According to this embodiment, the first limiting barrier 211 and the second limiting barrier 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 rotational position consistent with the direction of the vehicle seat, the first limiting barrier 211 can prevent the seat body 100 from sliding forward. Or when the seat body 100 is in a third rotational position opposite to the direction of the vehicle seat, the second limiting barrier 212 can prevent the seat body 100 from sliding backward. When the seat body 100 rotates to a direction transverse to the vehicle seat, due to the gap between the first limiting barrier 211 and the second limiting barrier 212, the seat body 100 can slide out relative to the base 200, for example, slide out towards the door. Optionally, the seat body 100 can partially extend 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, thereby avoiding the child from colliding with the vehicle frame.

[0101] Figure 3 This is a perspective view of the seat body 100 according to an embodiment of the present disclosure, to show the lower side of the seat body 100 more clearly. Side wings 120 extend to the seat portion 110, and a cover plate 150 is shaped to match the seat portion 110 and the side wings 120. According to this embodiment, for example, a triangular limiting protrusion 113 is provided at a forward position on the lower side of the cover plate 150, and advantageously, a limiting protrusion 113 is provided on each of the two cover plates 150 on both sides of the seat body 100.

[0102] from Figure 3 A sliding mechanism 300 can be seen in the recessed mounting portion 111 located on the lower side of the seat body 100. The recessed mounting portion 111 has a side wall and a top wall perpendicular to the side wall, which is formed by the lower side surface of the seat portion 110. The sliding mechanism 300 includes a sliding frame 310, a fixing frame 320, a first sliding rod 330 passing through the sliding frame 310, a locking rod 350, and a bottom cover 360.

[0103] According to this embodiment, the sliding frame 310 is fixedly connected to the seat body 110. The sliding frame 310 is constructed as a sliding piece 310, advantageously with sliding pieces 310 respectively provided on the two side walls of the recessed mounting portion 111. Each sliding piece 310 has a corresponding first angle groove 311 (e.g., a front angle groove provided near the front side of the seat body 110). The fixing frame 320 is constructed as a fixing piece 320, having a locking rod through hole 325 for fixing a locking rod 350. The fixing piece 320 is detachably locked (e.g., detachably locked) to the limiting support portion 224 of the base 200 by the locking rod 350. According to one embodiment of this disclosure, each of the front and rear ends of the fixing piece 320 is provided with a locking rod through hole 325 for fixing one front and one rear locking rod 350 respectively. Each front and rear locking rod 350 extends laterally and is disposed below the seat body 110. The sliding mechanism 300 includes a fixing plate 320 on each side, and the two ends of the locking rod 350 are respectively fixed to the locking rod through holes 325 of the two fixing plates 320.

[0104] The fixing piece 320 further has a first sliding rod through hole 323 for inserting and fixing the first sliding rod 330 (the first sliding rod through hole 323 is located, for example, near the front side of the seat body 110, so that the first sliding rod 330 is close to the front side of the seat body 110). The first sliding rod 330 extends into a first angled groove 311 on the sliding piece 310. The first angled groove 311 is used to allow the first sliding rod 330 on the fixing piece 320 to slide within it. The sliding piece 310 can then slide relative to the fixing piece 320 along the path provided by the first angled groove 311 to adjust the tilt angle of the seat body 100 relative to the base 200. According to this embodiment, the two fixing pieces 320 are located inside the two sliding pieces 310. The first sliding rod 330 is laterally extended below the seat body 110. The two ends of the first sliding rod 330 are respectively fixed to the first sliding rod through holes 323 of the two fixing pieces 320, and further extend into the first angled grooves 311 of the two sliding pieces 310. Alternatively, the first sliding rod 330 can be configured as two separate rods instead of a single rod. When adjusting the tilt angle of the seat body 110, the sliding bracket 310 slides relative to the fixed bracket 320, causing the seat body 110, which is fixedly connected to the sliding bracket 310, to slide relative to the fixed bracket 320.

[0105] According to this disclosure, the rear portion of the sliding mechanism 300 further includes a second sliding rod 340 and a second angled slide groove 321. The second angled slide groove 321 is disposed in the rear portion of the fixed frame 320. A second sliding rod mounting hole 314 is provided on the sliding frame 310 for inserting and fixing the second sliding rod 340 (the second sliding rod mounting hole 314 is located, for example, near the rear side of the seat body 110, so that the second sliding rod 340 is close to the rear side of the seat body 110). The second sliding rod 340 on the sliding frame 310 extends into the second angled slide groove 321 of the fixed frame 320. The second angled slide groove 321 on the fixed frame 320 is used for the first sliding rod 330 to slide within it. Thus, when adjusting the tilt 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 tilt angle of the seat body 110 along the path provided by the second angled slide groove 321.

[0106] The second sliding rod 340 extends laterally and is disposed on the lower side of the seat body 110. Both ends of the second sliding rod 340 pass through the second angle sliding grooves 321 on the two fixing plates 320, and are further fixed to the second sliding rod through holes 314 on the two sliding plates 310. Alternatively, the second sliding rod 340 may not be a single rod, but rather two separate rods. Alternatively, the two second sliding rod through holes 314 may be directly disposed on the two side walls of the recessed mounting portion 111.

[0107] According to this disclosure, the mounting bracket 320 is provided with an angle adjustment hole 324, which is composed of multiple holes and can be set to an angle range as needed for the seat body 100. The seat body 100 includes a release part 112 and a locking mechanism, such as a locking pin (not shown). The release part 112 is provided, for example, on the lower front side of the seat 110 to facilitate user pulling operation, and the locking mechanism is provided, for example, on the seat body 100. The locking mechanism cooperates with any of the angle adjustment holes 324 provided on the mounting bracket 320 to lock the tilt angle of the seat body 100. Pulling the release part 112 disengages the locking mechanism from the angle adjustment hole 324, allowing the seat body 100 to slide along the first and second slide tracks, and when the release part 112 is operated (or released) to lock the locking mechanism into the angle adjustment hole 324, the tilt angle position of the seat body 100 is fixed. Advantageously, the first sliding rod 330 can play a role in stabilizing the sliding.

[0108] According to this embodiment, the plurality of holes in the angle adjustment hole 324 are arranged along the extending direction of the first angle groove 311. When the locking mechanism 115 is inserted into the last hole of the angle adjustment hole 324, the seat body 100 is locked in the first angle position. When the locking mechanism 115 is inserted into the foremost hole of the angle adjustment hole 324, the seat body 100 is locked in the second angle position. This second angle position is the transition position of the seat body 100 between tilt angle adjustment and sliding pull-out. Continuing to pull the seat body 100 forward from this transition position will cause the seat body 100 to slide forward relative to the base 200.

[0109] According to one embodiment, the sliding frame 310, which is fixedly connected to the seat body 100, is provided with an angle adjustment hole 324, and a locking mechanism, such as a locking pin (not shown), is provided on the fixed frame 320.

[0110] According to this disclosure, the bottom cover 360 can be fixedly connected to the mounting bracket 320. The bottom cover 360 can be configured to have a bottom cover body 361 and a connecting portion 362, the connecting portion 362 being connected to the fixing pieces 320 on both sides of the seat body 100 respectively. The bottom cover 360 can cover the sliding mechanism 300 and / or the underside of the seat body 100 as needed, and can further assist in the fixed connection of the front and rear locking rods 350.

[0111] Figure 4 This is a perspective view of a seat body 100 according to an embodiment of the present disclosure. Figure 4 Removed from Figure 3 The cover plate 150 and the release part 112 are exposed, as are the mounting holes 114 for mounting the cover plate 150 and other structures.

[0112] According to this embodiment, the sliding piece 310 located on one side of the seat body 100 is divided into two separate parts, front and rear. In addition to the first angle slide groove 311, the front part is provided with a first pull-out slide groove 312 that communicates with and forms an angle with the first angle slide groove 311. The first pull-out slide groove 312 extends along the longitudinal direction of the seat body 100, enabling the seat body 100 to be slidably pulled out. An exemplary fixing hole 313 is also provided on the front part, through which the sliding piece 310 is fixedly connected to the seat body 100. A second sliding rod mounting hole 314 is provided on the rear part of the sliding piece 310.

[0113] Figure 5This is a fixing piece 320 according to an embodiment of the present disclosure. According to the present disclosure, the fixing piece 320 includes a second angle slide groove 321, a second pull-out slide groove 322 communicating with and at an angle to the second angle slide groove 321, a first sliding rod through hole 323, an angle adjustment hole 324, and two front and rear locking rod through holes 325. The second pull-out slide groove 322 extends along the longitudinal direction of the seat body 100, and the second pull-out slide groove 322 enables the seat body 100 to slide and be pulled out. The shape of the fixing piece 320 can be configured according to the lower side design of the seat body 100, and the present disclosure is not limited thereto.

[0114] Figure 6 This is a perspective view of a base 200 according to an embodiment of the present disclosure. The base 200 includes a base body 210, a rotating part 220, a support 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 via the vehicle seat connector 240. The support leg 230 is telescopic and contacts the vehicle floor, effectively ensuring the stability of the child safety seat. In this example, the support leg 230 is fixed to the front side below the base 200. According to this embodiment, the rear of the base 200 is designed to be higher than the front, so that the upper side of the base 200 is ramp-shaped.

[0115] According to this embodiment, a circular rotating part 220 for connecting the seat body 100 is provided on the upper side of the base body 210. The rotating part 220 is disposed in the circular opening in the middle of the base 200 and can rotate relative to the opening.

[0116] According to this embodiment, a saddle-shaped limiting support portion 224 is provided on the rotating portion 220. The rear portion of the limiting support portion 224 is designed to be higher than the front portion. A receiving portion 222 and a pivotable engaging hook 221 are provided on the upper side of the limiting support portion 224. On the outer side of the limiting support portion 224, an elongated clearance groove 223, for example, arc-shaped, is provided on the rotating portion 220.

[0117] According to this embodiment, the first limiting barrier 211 and the second limiting barrier 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, and a gap is formed between the first limiting barrier 211 and the second limiting barrier 212.

[0118] Figure 7 It is along Figure 1 Cross-sectional view of child safety seat 1 with section line II. Figure 7In this configuration, the seat body 100 is in a relatively upright first angle position, and the second sliding rod 340, fixed on the sliding plate 310, is at the top of the rearmost side of the second angle groove 321 (i.e., the rearmost side of the seat body). The locking mechanism 115, provided on the seat body 100, is located in the hole at the rearmost side of the angle adjustment hole 324 and locks the seat body 100 in the first angle position. The first angle groove 321 on the sliding plate 310 also slides relative to the first sliding rod 330 until the first sliding rod is at the top of the frontmost side of the first angle groove 311.

[0119] Figure 8 It is along Figure 1 Cross-sectional view of child safety seat 1 with section line II. Figure 8 In the middle, the seat body 100 from Figure 7 The first angle position is switched to a more flat second angle position. The second sliding rod 340 fixed on the sliding piece 310 is at the foremost bottom end of the second angle slide groove 321, which is also the turning point between the second angle slide groove 321 and the second pull-out slide groove 322. This turning point is the turning point between the tilt angle adjustment and the sliding pull-out of the seat body 100. Continuing to pull the seat body 100 forward from this turning point will cause the seat body 100 to slide forward relative to the base 200. Figure 8 In the middle, the locking mechanism 115 provided on the seat body 100 transitions from the last hole of the angle adjustment hole 324 to the first hole under the operation of the release part 112, and locks the seat body 100 in the second angle position. Figure 8 In the middle, the seat body 100 from Figure 7 The first angle position is changed to a more reclined second angle position. The first angle groove 311 on the sliding piece 310 also slides relative to the first sliding rod 330 until the first sliding rod 330 is at the bottom end of the first angle groove 311. It is also in the turning position between the first angle groove 311 and the first pull-out groove 312. This turning position is the turning position of the seat body 100 between angle adjustment and sliding pull-out.

[0120] By adding a lateral sliding section to the front and rear sliding tracks (in this embodiment, the lateral sliding of the base body 210 can be a lateral sliding that is approximately horizontal with the bottom surface of the base 200), the seat body 100 in the second angle position is allowed to slide out further, so that the seat body 100 is closer to the door frame or even pulled out of the door frame. When the seat body 100 is in a lateral rotation position, and when the seat body 100 is changed from a relatively upright first angle position to a relatively flat second angle position (according to this embodiment, the relatively flat second angle position is also the turning position), if the seat body 100 in the relatively flat second angle position is pulled forward, the first sliding rod 330 will enter the first pull-out slide groove 312 and slide within the first pull-out slide groove 312, and the second sliding rod 340 will enter the second pull-out slide groove 322 and slide within the second pull-out slide groove 322. The sliding frame 310 will then slide relative to the fixed frame 320 along the translation path provided by the first pull-out slide groove 312 and the second pull-out slide groove 322, causing the seat body 100 to be translated and slid out relative to the base 200 to adjust the horizontal position of the seat body 100 relative to the base 200.

[0121] According to this embodiment, the first pull-out slide 312 can be approximately horizontal with the bottom surface of the base 200, wherein the first pull-out slide 312 forms a first angle with the bottom surface of the base 200, the first angle being between 0 degrees and 5 degrees. The first angle slide 311 forms a second angle with the bottom surface of the base 200, the second angle being greater than the first angle. The second pull-out slide 322 can be approximately horizontal with the bottom surface of the base 200, wherein the second pull-out slide 322 forms a third angle with the bottom surface of the base 200, the third angle being between 0 degrees and 5 degrees. The second angle slide 321 forms a fourth angle with the bottom surface of the base 200, the fourth angle being greater than the third angle.

[0122] Figure 9 This is a perspective view of a child safety seat 1 according to the present disclosure. The seat body 100 rotates relative to the base body 210 fixed to the vehicle seat via a rotating part 220, so as to... Figure 1 The seat body 100 is rotated from its first rotational position, i.e., the direction in which the seat body 100 is aligned with the direction of the vehicle seat, to its second rotational position, which is perpendicular to the base body 210.

[0123] from Figure 9 As can be seen, the latch 350 of the sliding mechanism 300 is engaged in the receiving portion 222 of the rotating part 220 and fixed therein.

[0124] Figure 10This 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. In this position, if a user takes a child out, the child's head may hit the door frame.

[0125] Figure 11 This 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 translated and pulled out to the left of the base 200 relative to the base 200, so that the child will not bump into the door frame when being taken out of the vehicle. The limiting protrusion 113 installed on the underside of the cover plate 150 is disengaged from the first limiting barrier 211 and extends from the base 200.

[0126] Figure 12 It is along Figure 11 Cross-sectional view of child safety seat 1 along section line II-II. The first angle slide groove 311 and the first pull-out slide groove 312 provided in the sliding plate 310 are arranged in a mirror image of the second angle slide groove 321 and the second pull-out slide groove 322 provided in the fixed plate 320. Figure 11 and Figure 12 In the middle, the seat body 100 is pulled out to the left of the base 200 relative to the base 200 until the first sliding rod 330 is at the last end of the first pull-out groove 312, while the second sliding rod 340 fixed in the sliding piece 310 is at the foremost end of the second pull-out groove 322. The seat body 100 is slid out to the farthest position relative to the base 200, and the limiting protrusion 113 is not restricted by the first limiting barrier 211 or the second limiting barrier 212.

[0127] According to one embodiment, the sliding mechanism 300 includes a sliding frame 310, a fixed frame 320, a groove (e.g., a second angle groove 321 and a second pull-out groove 322) disposed on the fixed frame 320, and a sliding rod (e.g., a second sliding rod 340) fixed on the sliding frame 310. The second sliding rod 340 on the sliding frame 310 extends into the groove on the fixed frame 320 and slides therein. The sliding mechanism 300 of the embodiment may not include the first sliding rod 330, the first angle groove 311, and the first pull-out groove 312. By providing an angled groove and a pull-out groove that are interconnected and at an angle 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 tilt angle of the seat body 110, the sliding bracket 310 slides relative to the fixed bracket 320, and the sliding bracket 310 can adjust the tilt 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 changed from a relatively upright first angle position to a relatively flat second angle position, if the seat body 100 in the relatively flat second angle position is pulled forward, the sliding rod will enter the pull-out slide groove and slide therein. The sliding bracket 310 will then slide relative to the fixed bracket 320 along the translation path provided by the pull-out slide groove, causing the seat body 100 to be translated and slid out relative to the base 200 to adjust the horizontal position of the seat body 100 relative to the base 200.

[0128] According to one embodiment (e.g.) Figure 13The angle slide and the pull-out slide are, for example, a second angle slide 321 and a second pull-out slide 322 provided in the fixing frame 320. The pull-out slide 322 can be arc-shaped, so that when adjusting the horizontal position of the seat body 100 relative to the base 200, the tilt angle of the seat body 100 relative to the base 200 also changes. For example, when the seat body 100 is in a relatively upright first angle position, adjusting the tilt angle of the seat body 110 will cause the sliding frame 310 to slide relative to the fixing frame 320. The sliding frame 310 can adjust the tilt angle of the seat body 110 along the path provided by the angle slide 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 changed from a relatively upright first angle position to a relatively flat second angle position, and the seat body 100 is pulled forward, the sliding rod will enter the arc-shaped pull-out groove 322 and slide within it. The sliding bracket 310 will then slide relative to the fixed bracket 320 along the arc-shaped sliding path provided by the pull-out groove 322, causing the seat body 100 to slide out relative to the base 200. Thus, when adjusting the horizontal position of the seat body 100 relative to the base 200, the tilt angle of the seat body 100 relative to the base 200 also changes.

[0129] According to one embodiment, an angled groove and a pull-out groove, which are interconnected and at an angle, are provided on one of the sliding frame 310 and the fixed frame 320 to allow a sliding rod on the other of the sliding frame 310 and the fixed frame 320 to slide within them. The angled groove and the pull-out groove are, for example, a second angled groove 321 and a second pull-out groove 322 provided on the fixed frame 320 (e.g., ...). Figure 14The pull-out groove 322 further includes an angled first pull-out section 322a and a second pull-out section 322b, thereby enabling the seat body 100 to be further adjusted in tilt angle after being slid out. Specifically, when adjusting the tilt 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 tilt angle of the seat body 110 along the path provided by the angled groove 321. When the seat body 100 is in a lateral rotation position, and when the seat body 100 is shifted from a relatively upright first angle position to a relatively reclined second angle position, if the seat body 100 is pulled forward in the reclined second angle position, the sliding rod will enter the first pull-out section 322a of the pull-out groove 322 and slide within it. The sliding bracket 310 will then slide relative to the fixed bracket 320 along the translational path provided by the first pull-out section 322a of the pull-out groove 322, causing the seat body 100 to slide out 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, if the seat body 100 is pulled forward, the sliding rod will enter the second pull-out section 322b of the pull-out groove 322 and slide within it. The sliding bracket 310 can adjust the tilt angle of the seat body 110 along the path provided by the second pull-out section 322b.

[0130] According to one embodiment (e.g.) 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 a fixing frame 310. 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 angled sliding groove 311 and a first pull-out sliding groove 312 communicating with the first angled sliding groove 311 and forming an angle, wherein the first pull-out sliding groove 312 extends along the longitudinal direction of the seat body 100. The center line connecting the front and rear sides 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 slide groove 311 and the first pull-out slide groove 312 are arranged one in front of the other along 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. Furthermore, 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 communicating with the second angled sliding groove 321 and forming an angle, 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 slide groove 321 and the second pull-out slide groove 322 are arranged one in front of the other along the longitudinal direction of the seat body 100.

[0134] According to one embodiment, the first slider 330 and the first groove 31 of the sliding mechanism 300 are located in the front part of the sliding mechanism 300.

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

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

[0137] According to one embodiment, the sliding mechanism 300 further includes a limiting protrusion 113 disposed on the seat body 100. The limiting protrusion 113 cooperates with the limiting barriers 211 and 212 on the base 200, so that when the seat body 100 is in the same direction as 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 slide groove 312, or directly or indirectly block the second sliding member 340 from entering the second pull-out slide groove 322.

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

[0139] According to the seat sliding mechanism 300 disclosed herein, a horizontal sliding section and a limiting structure are added to the angle sliding groove, which solves the problem of inconvenience in carrying children into or out of existing child safety seats.

[0140] In this disclosure, by rotating the seat body 100 to a side position, it can be further slid out, bringing the seat body 100 closer to the door frame or even pulling it out of the door frame. This makes it easier for adults to put the child in or take the child out, improving the user experience and satisfaction of the child safety seat 1. Specifically, the front and rear sliding channels are set in two sections: an angle sliding channel and a pull-out sliding channel. The angle sliding channel is used to adjust the tilt angle of the seat body 100, while the pull-out sliding channel is used to further pull out the seat body 100, bringing it closer to the door. This method is simple in structure and easy to implement. Furthermore, by setting a limiting protrusion 113 on the seat body 100, and setting front and rear limiting barriers on the base 200 that cooperate with the limiting protrusion 113, the front and rear limiting barriers extend along the front and rear of the base 200. With symmetrical directional design, when the child safety seat 1 is in a forward or rearward position, the seat body 100 can only adjust its tilt angle under the action of the limiting protrusion 113 and the limiting barrier, and cannot be further slid out. However, when the seat body 100 is rotated to the side, the limiting protrusion 113 avoids the limiting barrier. Thus, by pulling the seat body 100, the seat body 100 can be further slid out along the pull-out groove, making the seat body 100 closer to the door, which makes it easier to put the child in or take the child out.

[0141] Since this disclosure can be embodied in various forms without departing from the spirit and substance of this disclosure, it should be understood that the above 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. Therefore, all variations falling within the scope of the claims or their equivalents should be covered by the claims.
