Description

Technical Field

[0001] This application relates to the field of child safety seat technology, and more specifically, to a child safety seat with rotation and sliding functions. Background Technology

[0002] A car child safety seat, also known as a child restraint system, is a seat designed specifically for children of different ages (or weights) and installed in a car to effectively improve the safety of children while traveling. Existing child restraint systems typically consist of a base and a seat that is detachably mounted on the base. When it is necessary to remove the child, first rotate the seat towards the door, then push the seat outwards to remove the child.

[0003] In related technologies, a rotating component and a push-pull component are installed on the rotating disc of the child car seat. The rotating component drives the push-pull component and the child car seat body to rotate, allowing the child car seat body to rotate freely at an angle according to the child's usage needs. At the same time, the push-pull component can also be moved laterally, thereby pushing the child car seat body outward for easy placement and removal of the child. In related technologies, the push-pull component is directly connected to the rotating disc. The rotating component drives the rotating disc to rotate, and then controls the push-pull component to slide on the rotating disc.

[0004] However, the relevant technology has at least one of the following problems: since the push-pull component is directly connected to the rotating plate, the seat will be pulled out directly. During this process, the sliding speed and sliding stroke of the push-pull component are difficult to control, which will affect the child in the seat and ultimately reduce the child seat experience. Summary of the Invention

[0005] This invention solves the technical problem that the sliding speed and sliding stroke of the push-pull component in a child seat are difficult to control, thereby reducing the user experience of the child seat.

[0006] To address the aforementioned problems, this invention provides a child safety seat with rotation and sliding functions. The child safety seat includes: a base assembly and a seat body mounted on the base assembly. The base assembly has an opening on at least one side. The base assembly includes: a base body; a rotating structure connected to the base body and capable of rotating on the base body; a push-pull structure connected to the rotating structure, the seat body mounted on the push-pull structure and capable of sliding the seat body on the rotating structure; and a sliding structure connected between the push-pull structure and the rotating structure and capable of sliding between the push-pull structure and the rotating structure. When the rotating structure drives the push-pull structure to rotate until the push-pull structure aligns with the opening, at least a portion of the seat body structure is exposed outside the opening through the cooperation of the push-pull structure and the sliding structure.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: by setting a sliding structure between the push-pull structure and the rotating structure, the sliding efficiency of the seat body is effectively guaranteed, so that the seat body can remain stable during the sliding process, avoiding any impact on the child during the sliding process; at the same time, with the cooperation of the push-pull structure and the sliding structure, the sliding speed and sliding stroke of the push-pull structure can be effectively controlled, ultimately improving the experience of the child safety seat.

[0008] Furthermore, in this invention, the rotating structure includes a rotating disk, and the sliding structure includes: a first sliding groove disposed on the rotating disk; a first sliding plate that cooperates with the first sliding groove, and the first sliding plate has at least one groove on the side facing the first sliding groove, allowing the first sliding plate to move within the first sliding groove; and at least one sliding plate ball mounted in the first groove, with the number of sliding plate balls corresponding one-to-one with the number of first grooves; wherein, when the first sliding plate moves relative to the first sliding groove, the sliding plate ball rotates between the first sliding groove and the first sliding plate.

[0009] Compared with existing technologies, the technical effects achieved by this solution are as follows: a two-stage sliding mechanism is formed between the first sliding plate, the sliding plate, the sliding plate ball bearing, and the rotating disk. The sliding plate ball bearing is placed in the first groove on the rotating disk and can slide a certain distance within the rotating disk. At the same time, the sliding plate ball bearing is also engaged in the first groove of the first sliding plate, and the sliding plate can slide relative to the sliding plate ball bearing, thus forming a two-stage sliding mechanism. The design of the two-stage sliding mechanism avoids the impact on children on the seat body during the sliding process of the push-pull structure, and also improves the stability of the push-pull structure during the sliding process.

[0010] Furthermore, in this invention, the push-pull structure includes a mounting plate and a sliding plate. The mounting plate is used to mount the seat body, and the sliding plate is used to realize the sliding between the push-pull structure and the rotating structure. The sliding structure further includes: a second sliding groove, which is disposed on the sliding plate and extends from a first end to a second end of the sliding plate; a third sliding groove, which is disposed on the sliding plate, offset from the second sliding groove, and extends from the second end to the first end of the sliding plate; a first limiting member, which is disposed at one end of the first sliding plate and can slide within the second sliding groove; and a second limiting member, which is disposed at the other end of the first sliding plate and can slide within the third sliding groove.

[0011] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: through the cooperation of the first limiting member and the second slide groove, and the second limiting member and the third slide groove, the stability of the sliding plate during the sliding process is ensured, and the risk of the sliding plate falling off the rotating disk during the sliding process is avoided.

[0012] Furthermore, in this invention, the sliding plate is provided with a base plate and a side plate, the second sliding groove is provided on the base plate, and a baffle facing the second sliding groove is provided on the side plate. The first limiting member includes: a first limiting post, one end of which is connected to the first sliding plate, and the other end of which extends away from the first sliding plate; a first limiting plate, one end of which is connected to the first limiting post, and the other end of which extends away from the first limiting post, and a first limiting space is formed between the first limiting plate, the first limiting post, and the first sliding plate; wherein, when the first limiting member slides in the second sliding groove, the baffle moves within the first limiting space.

[0013] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the setting of the first limiting post guides the sliding plate, allowing it to slide along the direction of the second sliding groove on the rotating disk, thus preventing the sliding plate from deviating; the setting of the first limiting plate prevents the sliding plate from falling off the rotating disk, thereby ensuring the safety of the child safety seat during rotation and sliding.

[0014] Furthermore, in this invention, the sliding plate is provided with a base plate, the third sliding groove is provided on the base plate, and the second limiting member includes: a second limiting post, one end of which is connected to the first sliding plate, and the other end of which extends away from the first sliding plate; a second limiting plate, which is connected to the second limiting post, and the second limiting plate extends to both sides from the second limiting post, forming a second limiting space and a third limiting space between the second limiting plate, the second limiting post, and the first sliding plate; wherein, when the second limiting member slides in the third sliding groove, the base plate moves within the second limiting space and the third limiting space.

[0015] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: The setting of the second limiting post also plays a guiding role in the sliding of the sliding plate, allowing the sliding plate to slide along the direction of the third sliding groove on the rotating disk, further preventing the sliding plate from deviating during the sliding process; The setting of the second limiting plate also prevents the sliding plate from falling off the rotating disk, further ensuring the safety of the child safety seat during rotation and sliding.

[0016] Furthermore, in this invention, the sliding structure further includes a third limiting member, which is disposed at one end of the first sliding plate near the second limiting member, for limiting the sliding stroke between the sliding plate and the first sliding plate.

[0017] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the setting of the third limiting component limits the sliding stroke of the sliding plate, ensuring the stability of the sliding of the push-pull structure.

[0018] Furthermore, in this invention, a notch is provided at the position of the first sliding plate near the second limiting member, and a third limiting member is provided at the notch. The third limiting member includes: an extension plate, one end of which is connected to the edge of the notch, and the other end of which extends toward the center of the notch; and a third limiting plate, which is provided on the extension plate. The third limiting plate extends from the extension plate toward a direction away from the first sliding plate, and the thickness of the third limiting plate increases sequentially in the extension direction of the extension plate.

[0019] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the thickness of the third limiting plate increases sequentially along the extension direction of the extension plate, which achieves a buffering effect. When the sliding plate moves along the direction of the extension plate during sliding, the third limiting plate can decelerate the sliding plate, further controlling the sliding speed of the sliding plate and improving the applicability of the child seat.

[0020] Furthermore, in this invention, the rotating disk is provided with a positioning hole, which is used to realize the positioning and installation between the rotating structure and the base body. The sliding structure also includes: a sliding groove, which is provided on the rotating disk and located on the side of the first sliding groove away from the positioning hole; and a sliding protrusion, which is provided on the sliding plate and can slide within the sliding groove.

[0021] Compared with existing technologies, the technical effects achieved by this solution are as follows: the sliding groove and sliding protrusion guide the sliding process of the push-pull structure, preventing the push-pull structure from falling off during the sliding process and ensuring the safety of the child safety seat during use.

[0022] Furthermore, in this invention, the sliding structure also includes: positioning grooves, two of which are respectively provided at both ends of the sliding groove. The positioning grooves can slide between the sliding groove and the sliding protrusion, and when the sliding protrusion slides to the positioning groove, the positioning and locking between the sliding plate and the rotating disk can be achieved.

[0023] Compared with the existing technology, the technical effect achieved by adopting this technical solution is that the positioning groove can slide between the sliding groove and the sliding protrusion, and when the sliding protrusion slides to the positioning groove, it can realize the positioning and locking between the sliding plate and the rotating disk, thereby achieving control over the stroke of the sliding plate.

[0024] Furthermore, in this invention, the rotating structure further includes: a toggle member, which is movably disposed on the rotating disk and is used to adjust the locking member disposed on the rotating disk relative to the base body between an unlocked state and a locked state; wherein, when the locking member is in the locked state, it restricts the rotation of the rotating structure relative to the base body; when the locking member is in the unlocked state, it enables the rotating structure to rotate relative to the base body.

[0025] Compared with existing technologies, the technical effects achieved by this solution are as follows: through the linkage between the actuating and locking components, the seat body can flexibly switch between rotating or restricting rotation relative to the base, thus reducing the difficulty of operation.

[0026] In summary, by adopting the technical solution of the present invention, the following technical effects can be achieved: i) By setting a sliding structure between the push-pull structure and the rotating structure, the sliding efficiency of the seat body is effectively guaranteed, so that the seat body can remain in a stable state during the sliding process, avoiding the impact on children during the sliding process; at the same time, with the cooperation of the push-pull structure and the sliding structure, the sliding speed and sliding stroke of the push-pull structure can be effectively controlled, ultimately improving the experience of the child safety seat. ii) A secondary sliding mechanism is formed between the first sliding plate, the sliding plate, the sliding plate ball bearing, and the rotating disk. The sliding plate ball bearing is placed in the first groove on the rotating disk and can slide a certain distance within the rotating disk. At the same time, the sliding plate ball bearing is also engaged in the first groove of the first sliding plate, and the sliding plate can slide relative to the sliding plate ball bearing, thus forming a secondary sliding mechanism. The secondary sliding mechanism avoids the impact on the child on the seat body during the sliding process of the push-pull structure, and also improves the stability of the push-pull structure during the sliding process. iii) The thickness of the third limiting plate increases sequentially along the extension direction of the extension plate, which achieves a buffering effect. When the sliding plate moves along the direction of the extension plate during the sliding process, the third limiting plate can slow down the slide, further control the sliding speed of the sliding plate, and improve the applicability of the child seat.

Detailed Implementation

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] This invention provides a child safety seat with rotation and sliding functions, see [link to relevant documentation]. Figure 1 as well as Figure 2 The child safety seat 100 includes a base assembly 20 and a seat body 10 mounted on the base assembly 20. The base assembly 20 has an opening 211 on at least one side. The base assembly 20 includes a base body 21, a rotating structure 22, a push-pull structure 23, and a sliding structure 30. The rotating structure 22 is connected to the base body 21 and can rotate on the base body 21. The push-pull structure 23 is connected to the rotating structure 22, and the seat body 10 is mounted on the push-pull structure 23, which can drive the seat body 10 to slide on the rotating structure 22. The sliding structure 30 is connected between the push-pull structure 23 and the rotating structure 22 and can slide between the push-pull structure 23 and the rotating structure 22.

[0031] Furthermore, when the rotating structure 22 drives the push-pull structure 23 to rotate, and the push-pull structure 23 corresponds to the position of the opening 211, with the cooperation of the push-pull structure 23 and the sliding structure 30, the push-pull structure 23 and the seat body 10 can slide outward along the direction of the opening 211, so that at least part of the structure of the seat body 10 is exposed outside the opening 211, ultimately allowing the passenger to take the child out.

[0032] It should be noted that by setting a sliding structure 30 between the push-pull structure 23 and the rotating structure 22, the sliding efficiency of the seat body 10 is effectively guaranteed, so that the seat body 10 can remain stable during the sliding process, avoiding the impact on the child during the sliding process; at the same time, with the cooperation of the push-pull structure 23 and the sliding structure 30, the sliding speed and sliding stroke of the push-pull structure 23 can be effectively controlled, ultimately improving the experience of the child safety seat.

[0033] Preferred, see Figure 3 as well as Figure 4 The rotating structure 22 includes a rotating disk 221, and a positioning hole 2211 is provided at the center of the rotating disk 221. The positioning hole 2211 is used to realize the positioning and installation between the rotating structure 22 and the base body 21. Two sliding structures 30 are provided, and the two sliding structures 30 are located on both sides of the positioning hole 2211. Correspondingly, a positioning shaft 212 is provided on the base body 21. When the rotating structure 22 is connected to the base body 21, the positioning hole 2211 on the rotating disk 221 is sleeved on the positioning shaft 212. It should be noted that in this invention, both the positioning hole 2211 and the positioning shaft 212 are set as circular structures. Therefore, when the rotating disk 221 is sleeved on the positioning shaft 212 through the positioning hole 2211, the rotating structure 22 and the rotating disk 221 can rotate relative to the base body 21.

[0034] Furthermore, the rotating structure 22 also includes a locking structure 222 and a toggle member 223; the toggle member 223 is movably disposed on the rotating disk 221 and is used to adjust the rotating disk 221 to a locked or unlocked state; the locking structure 222 is disposed near the edge of the rotating disk 221 and is located between the rotating disk 221 and the toggle member 223; it should be noted that in this invention, there are two toggle members 223 and two locking structures 222, which are respectively disposed on both sides of the positioning hole 2211; the arrangement of two toggle members 223 and two locking structures 222 can simultaneously adjust the rotation of the rotating disk 221, or if one toggle member 223 malfunctions, the rotation of the rotating disk 221 can still be controlled by controlling the other toggle member 223; of course, the number of toggle members 223 and locking structures 222 can be set to one or more, and the specific number can be set according to the actual situation or the actual needs of the user, and is not limited to the number limited in this invention.

[0035] Preferred, see Figures 4-7 The sliding structure 30 includes a first sliding groove 2241 and a first sliding plate 31. The first sliding groove 2241 is disposed on the rotating disk 221, and there are two sets of the first sliding groove 2241. The two sets of the first sliding groove 2241 are disposed on both sides of the positioning hole 2211 of the rotating disk 221, and the first sliding groove 2241 on each side is located between the positioning hole 2211 and the locking structure 222. The first sliding plate 31 cooperates with the first sliding groove 2241, and at least one first groove 313 is provided on the side of the first sliding plate 31 facing the first sliding groove 2241. The first sliding plate 31 can move in the first sliding groove 2241. It should be noted that the number of first grooves 313 is the same as the number of first sliding grooves 2241.

[0036] Preferably, the sliding structure 30 includes: a slide rail 224; the slide rail 224 is disposed on the rotating disk 221, and two slide rails 224 are provided, the two slide rails 224 are respectively located on both sides of the positioning hole 2211, and a first groove 2241 is disposed on the slide rail 224, wherein the slide rail 224 is a protrusion structure disposed on one side of the rotating disk 221; it should be noted that, in this invention, each group of first grooves 2241 is provided with two, and the two first grooves 2241 are disposed on both sides of the slide rail 224 (see Figure 8 ), and the length of the first groove 2241 is slightly less than the length of the slide rail 224.

[0037] Preferred, see Figure 6 and Figure 8 The sliding structure 30 further includes: a second sliding groove 2331 and a first limiting member 311; the second sliding groove 2331 is disposed on the sliding plate 231 and extends from one end of the sliding plate 231 to the other end; the first limiting member 311 is disposed on one end of the first sliding plate 31 and can slide within the second sliding groove 2331.

[0038] Furthermore, the sliding plate 231 is provided with a base plate 233 and a side plate 234. The second sliding groove 2331 is provided on the base plate 233, and the side plate 234 is provided with a baffle 2341 facing the second sliding groove 2331. The first limiting member 311 includes: a first limiting post 3111 and a first limiting plate 3112. One end of the first limiting post 3111 is connected to the first sliding plate 31, and the other end extends away from the first sliding plate 31. One end of the first limiting plate 3112 is connected to the first limiting post 3111, and the other end extends away from the first limiting post 3111. A first limiting space 3113 is formed between the first limiting plate 3112, the first limiting post 3111 and the first sliding plate 31. When the first limiting member 311 slides in the second sliding groove 2331, the baffle 2341 moves in the first limiting space 3113.

[0039] Preferably, in this invention, two second sliding grooves 2331 are provided, and the two second sliding grooves 2331 are arranged in parallel. Correspondingly, two first limiting members 311 are also provided. The two second sliding grooves 2331 are located on both sides of the sliding plate 231, and the two corresponding first limiting members 311 are located in the two second sliding grooves 2331 on both sides of the sliding plate 231. To ensure the stability of the sliding plate 231 during the sliding process and to prevent wobbling, the two first limiting plates 3112 in the two second sliding grooves 2331 extend in opposite directions (see details). Figure 6 When the sliding plate 231 slides in the vertical direction, the two first limiting plates 3112 extend in opposite directions, thus ensuring that the sliding plate 231 will not wobble in the horizontal direction. It should be noted that since the first limiting member 311 is set after the first limiting post 3111 and the first limiting plate 3112, it can already limit the sliding plate 231. The two first limiting members 311 further enhance the limitation of the sliding plate 231, ultimately improving the stability of the child safety seat 100.

[0040] Preferably, the sliding structure 30 further includes: a third sliding groove 2332 and a second limiting member 312; the third sliding groove 2332 is disposed on the sliding plate 231, and the third sliding groove 2332 and the second sliding groove 2331 are offset from each other; the second limiting member 312 is disposed at the other end of the first sliding plate 31, that is, the second limiting member 312 is disposed at the end of the first sliding plate 31 away from the first limiting member 311, and the second limiting member 312 can slide within the third sliding groove 2332; it should be noted that in this invention, the parallelism between the third sliding groove 2332 and the second sliding groove 2331 plays a guiding role for the sliding of the sliding plate 231.

[0041] Furthermore, the third slide groove 2332 is disposed on the base plate 233, and the second limiting member 312 includes: a second limiting post 3121 and a second limiting plate 3122; one end of the second limiting post 3121 is connected to the first sliding plate 31, and the other end extends away from the first sliding plate 31; the second limiting plate 3122 is connected to the second limiting post 3121, and the second limiting plate 3122 extends to both sides from the second limiting post 3121, forming a second limiting space 3123 and a third limiting space 3124 between the second limiting plate 3122, the second limiting post 3121 and the first sliding plate 31, that is, the second limiting member 312 has a "T" shaped structure; wherein, when the second limiting member 312 slides in the third slide groove 2332, the base plate 233 moves within the second limiting space 3123 and the third limiting space 3124.

[0042] Preferred options, see also Figure 8The sliding structure 30 further includes: at least one sliding ball 33 and a fixing plate 32; the sliding ball 33 is installed in the first groove 313, and the number of sliding balls 33 corresponds one-to-one with the number of first grooves 313; wherein, when the first sliding plate 31 moves relative to the first sliding groove 2241, the sliding ball 33 rotates between the first sliding groove 2241 and the first sliding plate 31; the fixing plate 32 is located between the first sliding plate 31 and the first sliding groove 2241, and the fixing plate 32 is provided with a second groove 321. When the sliding ball 33 is installed in the first groove 313, the fixing plate 32 is located outside the sliding ball 33. The fixing plate 32 is used to fix the sliding ball 33, further preventing the sliding ball 33 from sliding during the sliding process; at the same time, the number of second grooves 321 is the same as the number of first grooves 313 and sliding balls 33.

[0043] Specifically, a secondary sliding mechanism is formed between the first sliding plate 31, the sliding plate 231, the sliding plate ball 33, and the rotating disk 221. The sliding plate ball 33 is placed in the first sliding groove 2241 on the rotating disk 221 and can slide a certain distance within the rotating disk 221. At the same time, the sliding plate ball 33 is also engaged in the first groove 313 of the first sliding plate 31, and the sliding plate 231 can slide relative to the sliding plate ball 33, thereby forming a secondary sliding mechanism. It should be noted that in this invention, the sliding stroke of the sliding plate 231 relative to the sliding plate ball 33 is twice the sliding stroke of the sliding plate ball 33 relative to the rotating disk 221. The secondary sliding mechanism avoids the impact on the child on the seat body 10 during the sliding process of the push-pull structure 23, and also improves the stability of the push-pull structure 23 during the sliding process.

[0044] Furthermore, the fixing plate 32 is provided with multiple locking buckles 322, and the multiple locking buckles 322 are evenly distributed on both sides of the fixing plate 32. Multiple locking slots 314 are provided on both sides of the first sliding plate 31. The number of locking buckles 322 and locking slots 314 is the same. The fixing plate 32 and the first sliding plate 31 can be locked together by locking buckles 322 and locking slots 314. In this process, the locking buckles 322 and locking slots 314 are engaged one-to-one.

[0045] Preferred, see Figure 9 as well as Figure 10 The sliding structure 30 also includes a third limiting member 316, which is disposed at one end of the first sliding plate 31 near the second limiting member 312, and is used to limit the sliding stroke between the sliding plate 231 and the first sliding plate 31.

[0046] Furthermore, the first slide plate 31 has a notch 315 near the second limiting member 312, and a third limiting member 316 is disposed in the notch 315. The third limiting member 316 includes an extension plate 3161 and a third limiting plate 3162. One end of the extension plate 3161 is connected to the edge of the notch 315, and the other end extends toward the center of the notch 315. The third limiting plate 3162 is disposed on the extension plate 3161. The third limiting plate 3162 extends from the extension plate 3161 in a direction away from the first slide plate 31, and the thickness of the third limiting plate 3162 increases sequentially in the extension direction of the extension plate 3161.

[0047] Preferred, see Figures 11-14 The push-pull structure 23 includes a mounting plate 232 and a sliding plate 231. The mounting plate 232 is used to mount the seat body 10, and the sliding plate 231 is used to realize the sliding between the push-pull structure 23 and the rotating structure 22. It should be noted that in this invention, there are two sliding plates 231, which are arranged in parallel, and both ends of the two sliding plates 231 are connected by connectors 235. At the same time, there are four mounting plates 232, which are respectively arranged at both ends of the two sliding plates 231. The four mounting plates 232 are used to mount the seat body 10.

[0048] Preferably, the sliding structure 30 further includes: a sliding groove 229, a sliding protrusion 2311, and a positioning groove 2291; the sliding groove 229 is disposed on the rotating disk 221 and located on the side of the first sliding groove 2241 away from the positioning hole 2211; the sliding protrusion 2311 is disposed on the sliding plate 231 and can slide within the sliding groove 229; in this invention, two positioning grooves 2291 are provided and are respectively disposed at both ends of the sliding groove 229, and the positioning grooves 2291 can slide between the sliding groove 229 and the sliding protrusion 2311. Furthermore, when the sliding protrusion 2311 slides to the positioning groove 2291, it can achieve positioning and locking between the sliding plate 231 and the rotating disk 221. At the same time, the sliding groove 229 is arranged parallel to the first sliding groove 2241, the second sliding groove 2331 and the third sliding groove 2332. It should be noted that the sliding groove 229 and the positioning groove 2291 can also be arranged on the sliding plate 231, and the corresponding sliding protrusion 2311 can be arranged on the rotating disk 221, as long as the sliding cooperation between the rotating disk 221 and the sliding plate 231 can be satisfied, and the arrangement position is not limited to that in this invention.

[0049] Furthermore, the positioning groove 2291 includes a first positioning groove 2292 and a second positioning groove 2293. The sliding protrusion 2311 can cooperate with the first positioning groove 2292 and the second positioning groove 2293 respectively. The sliding protrusion 2311 can slide between the first positioning groove 2292, the sliding groove 229, and the second positioning groove 2293, thereby achieving soft locking between the sliding plate 231 and the rotating disk 221. When the sliding plate 231 is in the initial position, the sliding protrusion 2311... It can be connected to the first positioning groove 2292. When the sliding plate 231 is pulled to its longest position, the sliding protrusion 2311 can be connected to the second positioning groove 2293. When the sliding plate 231 is pushed forward or backward, the sliding protrusion 2311 can deform and can disengage from the first positioning groove 2292 or the second positioning groove 2293. In other positions, the sliding protrusion 2311 can move in the sliding groove 229, thereby realizing the soft locking of the sliding plate 231 in the initial position and the longest position.

[0050] Furthermore, in this invention, there are two sliding grooves 229, two first positioning grooves 2292 and two second positioning grooves 2293, which are located on both sides of the rotating disk 221 and sandwiched between the sliding structure 30 and the locking structure 222.

[0051] Preferred, see Figure 4 as well as Figure 15 The rotating structure 22 further includes a toggle member 223, which is movably disposed on the rotating disk 221 and is used to adjust the locking member 228 disposed on the rotating disk 221 between the unlocked state and the locked state relative to the base body 21. At the same time, a locking groove (not shown in the figure) is provided on the base body 21 to engage with the locking member 228. When the locking member 228 engages with the locking groove, the rotating disk 221 is in the locked state. When the locking member 228 is separated from the locking groove, the rotating disk 221 is in the unlocked state. When the locking member 228 is in the locked state, it restricts the rotation of the rotating structure 22 relative to the base body 21. When the locking member 228 is in the unlocked state, it allows the rotating structure 22 to rotate relative to the base body 21.

[0052] Furthermore, a rope (not shown in the figure) is provided between the actuating member 223 and the locking member 228. The rope is installed in the rope channel 226, and an elastic member 227 is connected between the rope and the locking member 228. By adjusting the actuating member 223, the rope can drive the elastic member 227 to extend or retract, and then the elastic member 227 can drive the locking member 228 to move, so that the locking member 228 can engage or disengage with the locking groove, thereby achieving the purpose of unlocking and locking between the rotating disk 221 and the base body 21.

[0053] Preferred, see Figures 16-18 The base body 21 has two openings 211, located on opposite sides of the base body 21. When the base assembly 20 is in the initial position, the locking member 228 engages with the locking groove, and the locking member 228 is in a locked state. Since the openings 211 of the base body 21 are located on the left and right sides (see...), Figure 16 At this point, because the opening 211 is not aligned with the direction of the push-pull structure 23, the push-pull structure 23 cannot slide on the rotating disk 221; when the actuating member 223 is adjusted, causing the rope to extend and retract the elastic member 227, thus separating the locking member 228 from the locking groove, the rotating structure 22 can drive the push-pull structure 23 to rotate until the push-pull structure 23 corresponds to the position of the opening 211 (see...). Figure 17 At this point, the opening 211 is aligned with the push-pull structure 23; furthermore, with the cooperation of the push-pull structure 23 and the sliding structure 30, at least a portion of the structure of the seat body 10 is exposed outside the opening 211 (see...). Figure 18 This allows passengers to carry the child out. It should be noted that since there are two openings 211 in this invention, when the rotating structure 22 drives the push-pull structure 23 to rotate, it can rotate 90° clockwise or counterclockwise. Figure 17 for Figure 16 The rotating structure 22 drives the push-pull structure 23 to rotate 90° clockwise.

[0054] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
