[0056] In addition, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0057] It should be noted that, without conflict, the features in the embodiments of the present utility model can be combined with each other.

[0058] As mentioned in the background art, a child safety seat is a safety device specially designed for children of different ages or body types. Installed in a vehicle, it can effectively improve the safety of children when riding in the car.

[0059] In the prior art, the playability and interestingness of child safety seats are low, which reduces children's acceptance of child safety seats. Specifically, in order to facilitate an adult to take out or place a child, the backrest can be rotated by 90 degrees and then slid out relative to the base. However, during this process, the backrest is in a horizontal sliding process, lacking playability and interestingness, and reducing children's acceptance of child safety seats.

[0060] In view of this, please refer to Figures 1-21 , the safety seat moving device and the child safety seat 1000 provided in the embodiments of the present utility model can solve this problem, and will be described in detail hereinafter.

[0061] Please refer to Figures 1-5 , an embodiment of the present utility model provides a child safety seat 1000. The child safety seat 1000 includes a backrest 1100 and a safety seat moving device. The backrest 1100 is connected to a moving frame 300 (described in detail below) of the safety seat moving device. The safety seat moving device can move the backrest 1100, change the center of gravity height of the backrest 1100, and improve the playability and interestingness of the child safety seat 1000.

[0062] Specifically, the safety seat moving device includes a base 100, a rotating disk 200, and a moving frame 300. The rotating disk 200 is rotatably installed on the base 100. The rotating disk 200 is provided with a first curved chute 301. The moving frame 300 is connected to the rotating disk 200. The moving frame 300 is slidably engaged with the first curved chute 301. The moving frame 300 is used to connect the backrest 1100.

[0063] Among them, the moving frame 300 is used to change the height of the moving frame 300 during the process of sliding relative to the first curved chute 301. Please refer to Figures 3-5, when an adult needs to take out or place a child, after the rotating disk 200 rotates relative to the base 100 (generally rotates 90 degrees), the backrest 1100 connected to the moving frame 300 can face the car door. After that, the moving frame 300 slides relative to the first curved chute 301 and approaches the car door. Equivalently, after the backrest 1100 rotates and extends, it is in the extended state.

[0064] During this process, since the height of the moving frame 300 will change, and thus the center of gravity height of the backrest 1100 can change, which improves the playability and interestingness of the child safety seat 1000, better conforms to the playful nature of children, and increases children's acceptance of the child safety seat 1000.

[0065] Specifically, in this embodiment, in order to make the movement process of the backrest 1100 more stable, the rotating disk 200 is further provided with a second curved chute 302. The second curved chute 302 and the first curved chute 301 are spaced apart. Specifically, the first curved chute 301 and the second curved chute 302 are parallelly distributed. The shape of the first curved chute 301 can be understood as arc-shaped, and the shape of the first curved chute 301 is the same as that of the second curved chute 302. The moving frame 300 is simultaneously slidably engaged with the first curved chute 301 and the second curved chute 302.

[0066] Among them, the moving frame 300 includes two support plates 310 and a sliding rod 320. The sliding rod 320 is connected to the two support plates 310 at the same time. The two support plates 310 are spaced apart. The support plates 310 are provided with connection holes. The two ends of the sliding rod 320 respectively penetrate and are connected to the connection holes of the two support plates 310. The sliding rod 320 is simultaneously slidably engaged with the first curved chute 301 and the second curved chute 302. That is, the two ends of the sliding rod 320 passing through the two support plates 310 are respectively slidably engaged with the first curved chute 301 and the second curved chute 302. The support plates 310 are used to connect the backrest 1100.

[0067] In this embodiment, as Figure 6 and Figure 7 shown, the heights at both ends of the first curved chute 301 are greater than the height in the middle of the first curved chute 301. Among them, the heights at both ends of the first curved chute 301 (which can be understood as the left end and the right end of the first curved chute 301) are the same.

[0068] Among them, Figure 6 it can be understood as the initial position of the moving frame 300 after the rotating disk 200 rotates relative to the base 100. The sliding rod 320 of the moving frame 300 is located at the left end of the first curved chute 301. Figure 7It can be understood as the maximum extended position of the moving frame 300 after sliding relative to the rotating disk 200 from the initial position. At this time, the sliding rod 320 of the moving frame 300 is located at the right end of the first curved chute 301, facilitating adults to take out or place children.

[0069] It can be seen that during the process of the moving frame 300 moving from Figures 6-7 In addition to moving to the right, the moving frame 300 will gradually descend during this process, and the center of gravity of the backrest 1100 will also descend. Then the moving frame 300 will gradually rise, and the center of gravity of the backrest 1100 will rise, improving the playability and interestingness of the child safety seat 1000. The way the sliding rod 320 moves relative to the second curved chute 302 can refer to the way the sliding rod 320 moves relative to the first curved chute 301, which will not be elaborated here. At the same time, when the moving frame 300 is in the maximum extended state, the height of the backrest 1100 can be equal to the height of the backrest 1100 when the moving frame 300 is in the initial state.

[0070] Of course, in some embodiments, as Figure 12 and Figure 13 shown, the heights at both ends of the first curved chute 301 are greater than the height in the middle of the first curved chute 301, and the height at one end of the first curved chute 301 is higher than the height at the other end of the first curved chute 301. That is, the height at the left end of the first curved chute 301 is less than the height at the right end of the first curved chute 301.

[0071] Among them, Figure 12 It can be understood as the initial position of the moving frame 300 after the rotating disk 200 rotates relative to the base 100. The sliding rod 320 of the moving frame 300 is located at the left end of the first curved chute 301. Figure 13 It can be understood as the maximum extended position of the moving frame 300 after sliding relative to the rotating disk 200 from the initial position. At this time, the sliding rod 320 of the moving frame 300 is located at the right end of the first curved chute 301, facilitating adults to take out or place children. The specific movement process of the moving frame 300 can refer to the movement process of the moving frame 300 mentioned in the above Figure 6 and Figure 7 The difference is that when the moving frame 300 is in the maximum extended position, the height of the backrest 1100 can be greater than the height of the backrest 1100 when the moving frame 300 is in the initial position.

[0072] In addition, since the heights at both ends of the first curved chute 301 are greater than the height in the middle of the first curved chute 301, when the backrest 1100 starts to slide, the backrest 1100 will first gradually descend. At the same time, according to the decomposition of forces, there will be a Figure 6 and Figure 7The initial component force for the middle moving frame 300 to extend rightward makes the initial sliding process of the backrest 1100 more labor-saving and has a boosting feeling compared to the existing backrest in the horizontal sliding process.

[0073] In some embodiments, it may also be that, as Figure 8 and Figure 9 shown, the heights at both ends of the first curved chute 301 are less than the height in the middle of the curved chute, and among them, the heights at both ends of the first curved chute 301 are the same.

[0074] Among them, Figure 8 it can be understood as the initial position of the moving frame 300 after the rotating disk 200 rotates relative to the base 100. The sliding rod 320 of the moving frame 300 is located at the left end of the first curved chute 301. Figure 9 It can be understood as the maximum extended position of the moving frame 300 after sliding relative to the rotating disk 200 from the initial position. At this time, the sliding rod 320 of the moving frame 300 is located at the right end of the first curved chute 301, which is convenient for an adult to take out or place a child.

[0075] It can be seen that during the process of the moving frame 300 from Figures 8-9 , in addition to moving rightward, the moving frame 300 will gradually rise, the center of gravity of the backrest 1100 rises, and then the moving frame 300 gradually descends, and the center of gravity of the backrest 1100 descends, which improves the playability and interestingness of the child safety seat 1000. The way the sliding rod 320 moves relative to the second curved chute 302 can refer to the way the sliding rod 320 moves relative to the first curved chute 301, which will not be elaborated here. At the same time, when the moving frame 300 is in the maximum extended state, the height of the backrest 1100 can be equal to the height of the backrest 1100 when the moving frame 300 is in the initial state.

[0076] In some embodiments, in order to make the moving frame and the backrest move more smoothly, it may also be that the number of the first curved chutes 301 is multiple, the number of the second curved chutes 302 is also multiple, the multiple second curved chutes 302 and the multiple first curved chutes 301 correspond one by one, the height of at least one first curved chute 301 is greater than that of the remaining first curved chutes 301, and at the same time, the height of at least one second curved chute 302 is greater than that of the remaining second curved chutes 302. The number of the sliding rods 320 of the moving frame 300 is also multiple, the multiple sliding rods 320 and the multiple first curved chutes 301 correspond one by one, and the multiple sliding rods 320 are simultaneously connected to two support plates 310. Here, "multiple" can be understood as at least two.

[0077] For example, as Figure 10 and Figure 11As shown, the number of the first curved chutes 301, the number of the second curved chutes 302, and the number of the sliding rods 320 are all two. The heights at both ends of the first curved chute 301 are greater than the height in the middle of the first curved chute 301. The heights at both ends of the second curved chute 302 are greater than the height in the middle of the second curved chute 302. Both ends of each sliding rod 320 are slidably engaged with each first curved chute 301 and each second curved chute 302 respectively.

[0078] The height of one of the first curved chutes 301 is greater than the height of the other first curved chute 301. The distribution states of the two second curved chutes 302 can refer to the distribution states of the two first curved chutes 301 mentioned above.

[0079] Among them, Figure 10 It can be understood as the initial position of the moving frame 300 after the rotating disk 200 rotates relative to the base 100. Each sliding rod 320 of the moving frame 300 is located at the left end of each first curved chute 301. Figure 11 It can be understood as the maximum extended position of the moving frame 300 after sliding relative to the rotating disk 200 from the initial position. At this time, each sliding rod 320 of the moving frame 300 is located at the right end of each first curved chute 301, which is convenient for an adult to take out or place a child.

[0080] In other embodiments, the number of the first curved chutes 301, the number of the second curved chutes 302, and the number of the sliding rods 320 are all three. Both ends of each sliding rod 320 are slidably engaged with each first curved chute 301 and each second curved chute 302 respectively.

[0081] The height of one of the first curved chutes 301 is greater than the heights of the other two first curved chutes 301. At the same time, the heights of the other two first curved chutes 301 are different. The distribution states of the three second curved chutes 302 can refer to the distribution states of the three first curved chutes 301 mentioned above.

[0082] Please continue to refer to Figures 14-17 , of course, in other embodiments, it can also be that the support plate 310 of the moving frame 300 can be provided with a support chute 311. The sliding rod 320 is slidably engaged with the support chute 311, and the sliding rod 320 is slidably engaged with the first curved chute 301.

[0083] As Figure 14 described, in the initial state of the moving frame 300, the sliding rod 320 is at the right end of the support chute 311 ( Figure 16As shown, at the same time, the sliding rod 320 is at the left end of the first curved chute 301. During the rightward movement of the moving frame 300, first, the sliding rod 320 moves relative to the first curved chute 301 until the sliding rod 320 reaches the right end of the first curved chute 301. Then, under the action of the pulling force, the moving frame 300 is driven to continue sliding. At this time, the sliding rod 320 moves from the right end of the support chute 311 to the left end of the support chute 311, and the moving frame 300 can reach the maximum extended position. Figure 15 As shown.

[0084] The way the sliding rod 320 moves relative to the second curved chute 302 can refer to the way the sliding rod 320 moves relative to the first curved chute 301, which will not be elaborated here.

[0085] Please refer to Figure 17 , in order to make the sliding rod 320 move relative to the first curved chute 301 first and then relative to the support chute 311, the moving frame 300 further includes two limiting members 3111. The two limiting members 3111 are oppositely arranged in the support chute 311. The limiting member 3111 can be understood as a limiting convex structure, which can abut against the sliding rod 320 under a relatively small pulling force on the moving frame 300 to limit the sliding rod 320 at the right end of the support chute 311. After the sliding rod 320 moves to the right end of the first curved chute 301, the pulling force on the moving frame 300 is increased, and the sliding rod 320 can break away from the restraint of the two limiting members 3111. The sliding rod 320 moves from the right end of the support chute 311 to the left end of the support chute 311, and the moving frame 300 can reach the maximum extended position.

[0086] It should be noted that, in order to make the movement of the backrest 1100 smoother during the movement process, the safety seat moving device further includes rollers (not shown in the figure). The rollers are installed on the support plate 310 of the moving frame 300. Specifically, the number of rollers can be multiple, and each support plate 310 can be installed with a roller, and the rollers are used to roll and contact the rotating disc 200.

[0087] In some embodiments, in order to facilitate the moving frame 300 to stay at the initial position or the maximum extended position, please refer to Figure 18 and Figure 19 , the rotating disc 200 is further provided with at least one limiting chute 304. The end of the first curved chute 301 is communicated with the limiting chute 304. The moving frame 300 is slidably matched with the first curved chute 301 and the limiting chute 304. Among them, the height of the end of the limiting chute 304 far from the first curved chute 301 is lower than the height of the connection between the first curved chute 301 and the limiting chute 304.

[0088] Specifically, a limiting chute 304 is communicated with both the left end and the right end of the first curved chute 301. Since the height of the end of the limiting chute 304 far from the first curved chute 301 is lower than the height of the connection between the first curved chute 301 and the limiting chute 304, therefore, Figure 18 As shown in Figure 18 , in the initial state of the moving frame 300, the sliding rod 320 can stay in the limiting chute 304 communicated with the left end of the first curved chute 301 under the action of gravity. Under the action of pulling force, the moving frame 300 moves into the limiting chute 304 communicated with the right end of the first curved chute 301, and the sliding rod 320 can stay in the limiting chute 304 communicated with the right end of the first curved chute 301 under the action of gravity. At this time, the moving frame 300 is in the maximum extended position ( Figure 19 As shown in Figure 19 ), at this time, the backrest 1100 can be understood to be in a suspended stop state.

[0089] Of course, in some embodiments, it may also be that a limiting chute 304 is communicated with either the left end or the right end of the first curved chute 301.

[0090] Both the limiting chute 304 and the first curved chute 301 are in an arc-shaped structure. The arc trajectory of the limiting chute 304 and the arc trajectory of the first curved chute 301 can be tangent. At the same time, the center of the limiting chute 304 is located below the limiting chute 304, while the center of the first curved chute 301 can be located above the limiting chute 304.

[0091] Of course, a limiting chute 304 is also communicated with both ends of the second curved chute 302. For the specific connection state of the limiting chute 304 and the first curved chute 301, reference can be made to the above, and details will not be elaborated here.

[0092] Please refer to Figure 20 and combine with Figures 5-7 , in some embodiments, in order to facilitate the locking of the extended position of the backrest 1100 after the backrest 1100 of the seat rotates first and then slides out, and at the same time, the extended position of the backrest 1100 can be adjusted in multiple ways, the safety seat moving device further includes an elastic member 400. The elastic member 400 can be understood as a spring plate. A plurality of gear slots 303 are provided on the support plate 310 of the moving frame 300. The elastic member 400 is arranged on the rotating disc 200. Among them, the elastic member 400 is used for elastically abutting against any one of the gear slots 303 when the moving frame 300 slides relative to the first curved chute 301 to a first preset position.

[0093] The plurality of gear slots 303 are distributed in sequence from left to right. When the end of the spring plate abuts against the leftmost gear slot 303, the elastic member 400 can lock the extended state of the backrest 1100. This first preset position can be understood as the maximum extended position of the moving frame 300.

[0094] Of course, in other cases, when the moving frame 300 needs to be in a different extended position during the rightward movement, the first preset position can also be understood as the position where the end of the elastic piece abuts against other corresponding gear slots 303 (the gear slot 303 can be defined by adjacent protrusions, and the end of the elastic piece will undergo elastic deformation when abutting against and passing over the protrusions). When the end of the elastic piece abuts against other corresponding gear slots 303, the extended state of the chair back 1100 is locked.

[0095] Please refer to Figure 21 and in combination with Figures 5-7 , in some embodiments, other methods can also be used to lock the extended position of the chair back 1100. Specifically, the rotating disk 200 has a first limiting protrusion 210, and the support plate 310 of the moving frame 300 has a second limiting protrusion 330. Among them, the second limiting protrusion 330 is used to abut against the first limiting protrusion 210 when the moving frame 300 slides relative to the first curved chute 301 to a second preset position.

[0096] The second preset position here can be understood as Figure 7 as shown, the position of the moving frame 300 when the sliding rod 320 slides to the right end of the first curved chute 301. During the process of the sliding rod 320 sliding to the right end of the first curved chute 301, the second limiting protrusion 330 slides relative to the first limiting protrusion 210 and passes over the first limiting protrusion 210. Under the gravity of the chair back 1100 and the moving frame 300, the second limiting protrusion 330 abuts against the first limiting protrusion 210 to lock the extended state of the chair back 1100.

[0097] In order to also be able to adjust multiple extended positions of the chair back 1100, the number of the second limiting protrusions 330 can be multiple. The multiple second limiting protrusions 330 can be distributed in sequence along the direction of the rightward movement of the chair back 1100. When the moving frame 300 needs to be in different extended positions during the rightward movement, different second limiting protrusions 330 can abut against the first limiting protrusion 210 to lock different extended states of the chair back 1100.

[0098] It is easy to understand that the second preset position can also be understood as the position of the moving frame 300 when different second limiting protrusions 330 abut against the first limiting protrusion 210 to lock different extended states of the chair back 1100.

[0099] In summary, the child safety seat moving device includes a base 100, a rotating disc 200, and a moving frame 300. The rotating disc 200 is rotatably mounted on the base 100. The rotating disc 200 is provided with a first curved chute 301. The moving frame 300 is connected to the rotating disc 200 and is slidably engaged with the first curved chute 301. The moving frame 300 is used to connect to the backrest 1100.

[0100] Wherein, the moving frame 300 is used to change the height of the moving frame 300 during the process of sliding relative to the first curved chute 301. When an adult needs to take out or place a child, after the rotating disc 200 rotates relative to the base 100, the backrest 1100 connected to the moving frame 300 can face the car door. Then, the moving frame 300 slides close to the car door relative to the first curved chute 301. During this process, since the height of the moving frame 300 will change, the center of gravity height of the backrest 1100 can change, improving the playability and interestingness of the child safety seat 1000, better conforming to the playful nature of children, increasing children's acceptance of the child safety seat 1000, and reducing children's fear of the child safety seat 1000.

[0101] The child safety seat 1000 includes a backrest 1100 and the above-mentioned child safety seat moving device. The backrest 1100 is connected to the moving frame 300 of the child safety seat moving device. The child safety seat 1000 has all the functions of the above-mentioned child safety seat moving device.
