DETAILED DESCRIPTION

[0052] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0053] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative labor are within the scope of protection of the present application.

[0054] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0055] In the description of the present application, it should be noted that if the terms "upper", "lower", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly placed when the product of the present application is used, only for the convenience of describing the present application and simplifying the description, and it is not intended to indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the present application.

[0056] In addition, if the terms "first", "second" and the like appear, they are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

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

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

[0059] In the prior art, the child safety seat has low playability and interest, which reduces the acceptance of the child safety seat by children. Specifically, in order to facilitate an adult to take out or place a child, the chair back can be rotated by 90 degrees and then slid out relative to the base. However, in this process, the chair back is in a horizontal sliding process, which lacks playability and interest and reduces the acceptance of the child safety seat by children.

[0060] Therefore, referring to FIGS. 1-21, the safety seat moving device and the child safety seat 1000 provided in the embodiments of the present application can solve this problem, which will be described in detail below.

[0061] Referring to FIGS. 1-5, the child safety seat 1000 provided in the embodiments of the present application includes a chair back 1100 and a safety seat moving device connected with a moving frame 300 (to be described below) of the safety seat moving device. The safety seat moving device can move the chair back 1100 and change the height of the center of gravity of the chair back 1100, thereby improving the playability and interest of the child safety seat 1000.

[0062] Specifically, the safety seat moving device includes a base 100, a rotating disc 200, and a moving frame 300. The rotating disc 200 is rotatably installed on the base 100 and is provided with a first arc-shaped sliding groove 301. The moving frame 300 is connected with the rotating disc 200 and is slidably fitted in the first arc-shaped sliding groove 301. The moving frame 300 is used to connect the chair back 1100.

[0063] The moving frame 300 is used to change the height of the moving frame 300 during the sliding process relative to the first arc-shaped sliding groove 301. Referring to FIGS. 3-5, when an adult needs to take out or place a child, the rotating disc 200 is rotated relative to the base 100 (generally by 90 degrees), so that the chair back 1100 connected with the moving frame 300 can face the door. Then, the moving frame 300 is slid relative to the first arc-shaped sliding groove 301 to approach the door, which is equivalent to that the chair back 1100 is rotated and extended to be in an extended state.

[0064] In this process, the height of the moving frame 300 changes, and thus the height of the center of gravity of the chair back 1100 can change, thereby improving the playability and interest of the child safety seat 1000, which is more in line with the playful nature of children and increases the acceptance of the child safety seat 1000 by children.

[0065] Specifically, in the embodiment, in order to make the movement process of the chair back 1100 more stable, the rotating disc 200 is further provided with a second arc-shaped sliding groove 302, the second arc-shaped sliding groove 302 and the first arc-shaped sliding groove 301 are distributed in a spaced manner, specifically, the first arc-shaped sliding groove 301 and the second arc-shaped sliding groove 302 are distributed in parallel, the shape of the first arc-shaped sliding groove 301 can be understood as a circular arc shape, and the shape of the first arc-shaped sliding groove 301 is consistent with the shape of the second arc-shaped sliding groove 302, and the moving frame 300 is slidably fitted in the first arc-shaped sliding groove 301 and the second arc-shaped sliding groove 302.

[0066] The moving frame 300 comprises two support plates 310 and a sliding rod 320, the sliding rod 320 is connected with the two support plates 310, the two support plates 310 are distributed in a spaced manner, the support plate 310 is provided with a connecting hole, the two ends of the sliding rod 320 are respectively penetrated through and connected to the connecting holes of the two support plates 310, and the sliding rod 320 is slidably fitted in the first arc-shaped sliding groove 301 and the second arc-shaped sliding groove 302, that is, the two ends of the sliding rod 320 penetrating out of the two support plates 310 are slidably fitted in the first arc-shaped sliding groove 301 and the second arc-shaped sliding groove 302, and the support plate 310 is used for connecting the chair back 1100.

[0067] In the embodiment, as shown in FIGS. 6 and 7, the height of the two ends of the first arc-shaped sliding groove 301 is greater than the height of the middle part of the first arc-shaped sliding groove 301, wherein the heights of the two ends of the first arc-shaped sliding groove 301 (which can be understood as the left end and the right end of the first arc-shaped sliding groove 301) are the same.

[0068] Specifically, FIG. 6 can be understood as the initial position of the moving frame 300 after the rotating disc 200 is rotated relative to the base 100, the sliding rod 320 of the moving frame 300 is located at the left end of the first arc-shaped sliding groove 301, and FIG. 7 can be understood as the maximum extension position of the moving frame 300 after the moving frame 300 is slid relative to the rotating disc 200, at this time, the sliding rod 320 of the moving frame 300 is located at the right end of the first arc-shaped sliding groove 301, which is convenient for adults to take out or place the child.

[0069] It can be seen that in the process from FIG. 6 to FIG. 7, in addition to the process of moving to the right, the moving frame 300 also gradually descends, the center of gravity of the chair back 1100 descends, then the moving frame 300 gradually ascends, the center of gravity of the chair back 1100 ascends, which improves the playability and interest of the child safety seat 1000, the movement mode of the sliding rod 320 relative to the second arc-shaped sliding groove 302 can refer to the movement mode of the sliding rod 320 relative to the first arc-shaped sliding groove 301, which will not be described herein again, and in the case that the moving frame 300 is in the maximum extension state, the height of the chair back 1100 can be equal to the height of the chair back 1100 in the initial state of the moving frame 300.

[0070] Of course, in some embodiments, as shown in FIG. 12 and FIG. 13, the height of both ends of the first arc-shaped sliding groove 301 is greater than the height of the middle part of the first arc-shaped sliding groove 301, and the height of one end of the first arc-shaped sliding groove 301 is higher than the height of the other end of the first arc-shaped sliding groove 301, that is, the height of the left end of the first arc-shaped sliding groove 301 is less than the height of the right end of the first arc-shaped sliding groove 301.

[0071] FIG. 12 can be understood as the initial position of the moving frame 300 after the rotating disc 200 rotates relative to the base 100, and the sliding rod 320 of the moving frame 300 is located at the left end of the first arc-shaped sliding groove 301, and FIG. 13 can be understood as the maximum extension position of the moving frame 300 after the moving frame 300 slides from the initial position relative to the rotating disc 200, at this time, the sliding rod 320 of the moving frame 300 is located at the right end of the first arc-shaped sliding groove 301, which is convenient for adults to take out or place children. The specific movement process of the moving frame 300 can be referred to the movement process of the moving frame 300 mentioned in FIG. 6 and FIG. 7, the difference is that when the moving frame 300 is in the maximum extension position, the height of the chair back 1100 can be greater than the height of the chair back 1100 when the moving frame 300 is in the initial position.

[0072] In addition, since the height of both ends of the first arc-shaped sliding groove 301 is greater than the height of the middle part of the first arc-shaped sliding groove 301, when the chair back 1100 starts to slide, the chair back 1100 first gradually descends, and according to the decomposition of force, there is an initial component force of the moving frame 300 extending to the right in FIG. 6 and FIG. 7 when the chair back 1100 starts to slide. Compared with the existing chair back which is in the process of horizontal sliding, the initial sliding process of the chair back 1100 is more labor-saving and has a boost feeling.

[0073] In some embodiments, it can also be, as shown in FIG. 8 and FIG. 9, the height of both ends of the first arc-shaped sliding groove 301 is less than the height of the middle part of the arc-shaped sliding groove, and the height of both ends of the first arc-shaped sliding groove 301 is the same.

[0074] FIG. 8 can be understood as the initial position of the moving frame 300 after the rotating disc 200 rotates relative to the base 100, and the sliding rod 320 of the moving frame 300 is located at the left end of the first arc-shaped sliding groove 301, and FIG. 9 can be understood as the maximum extension position of the moving frame 300 after the moving frame 300 slides from the initial position relative to the rotating disc 200, at this time, the sliding rod 320 of the moving frame 300 is located at the right end of the first arc-shaped sliding groove 301, which is convenient for adults to take out or place children.

[0075] It can be seen that in the process from FIG. 8 to FIG. 9, in addition to the process of moving rightward, the moving frame 300 gradually rises, the center of gravity of the chair back 1100 rises, and then the moving frame 300 gradually descends, the center of gravity of the chair back 1100 descends, which improves the playability and interest of the child safety seat 1000. The movement mode of the sliding rod 320 relative to the second arc-shaped sliding groove 302 can refer to the movement mode of the sliding rod 320 relative to the first arc-shaped sliding groove 301, which will not be described here. At the same time, when the moving frame 300 is in the maximum extension state, the height of the chair back 1100 can be equal to the height of the chair back 1100 when the moving frame 300 is in the initial state.

[0076] In some embodiments, in order to make the moving frame and the chair back more stable during movement, the number of the first arc-shaped sliding grooves 301 can be multiple, and the number of the second arc-shaped sliding grooves 302 can also be multiple. The multiple second arc-shaped sliding grooves 302 and the multiple first arc-shaped sliding grooves 301 correspond one by one. The height of at least one first arc-shaped sliding groove 301 is greater than that of the remaining first arc-shaped sliding grooves 301. At the same time, the height of at least one second arc-shaped sliding groove 302 is greater than that of the remaining second arc-shaped sliding grooves 302. The number of the sliding rods 320 of the moving frame 300 can also be multiple. The multiple sliding rods 320 and the multiple first arc-shaped sliding grooves 301 correspond one by one, and the multiple sliding rods 320 are simultaneously connected to the two support plates 310. Here, “multiple” can be understood as at least two.

[0077] For example, as shown in FIG. 10 and FIG. 11, the number of the first arc-shaped sliding grooves 301, the number of the second arc-shaped sliding grooves 302, and the number of the sliding rods 320 are all two. The height of both ends of the first arc-shaped sliding groove 301 is greater than the height of the middle of the first arc-shaped sliding groove 301. The height of both ends of the second arc-shaped sliding groove 302 is greater than the height of the middle of the second arc-shaped sliding groove 302. Both ends of each sliding rod 320 are slidably matched with each first arc-shaped sliding groove 301 and each second arc-shaped sliding groove 302.

[0078] The height of one of the first arc-shaped sliding grooves 301 is greater than that of the other first arc-shaped sliding groove 301. The distribution state of the two second arc-shaped sliding grooves 302 can refer to the distribution state of the two first arc-shaped sliding grooves 301 mentioned above.

[0079] Among them, FIG. 10 can be understood as the initial position of the moving frame 300 after the rotating disc 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 arc-shaped sliding groove 301. FIG. 11 can be understood as the maximum extension position of the moving frame 300 after the moving frame 300 slides relative to the rotating disc 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 arc-shaped sliding groove 301, which is convenient for adults to take out or place the child.

[0080] In other embodiments, the number of the first arc-shaped sliding grooves 301, the number of the second arc-shaped sliding grooves 302 and the number of the sliding rods 320 are all three, and two ends of each sliding rod 320 are respectively slidably matched with each first arc-shaped sliding groove 301 and each second arc-shaped sliding groove 302.

[0081] The height of one of the first arc-shaped sliding grooves 301 is greater than the height of the other two first arc-shaped sliding grooves 301, and the height of the other two first arc-shaped sliding grooves 301 is different. The distribution state of the three second arc-shaped sliding grooves 302 can refer to the distribution state of the three first arc-shaped sliding grooves 301 mentioned above.

[0082] Please continue to refer to FIGS. 14-17. Of course, in other embodiments, the support plate 310 of the moving frame 300 can be provided with a support sliding groove 311, and the sliding rod 320 is slidably matched with the support sliding groove 311 and the first arc-shaped sliding groove 301.

[0083] As shown in FIG. 14, in the initial state, the sliding rod 320 is at the right end of the support sliding groove 311 (shown in FIG. 16), and at the same time, the sliding rod 320 is at the left end of the first arc-shaped sliding groove 301. During the movement of the moving frame 300 to the right, first, the sliding rod 320 moves relative to the first arc-shaped sliding groove 301 until the sliding rod 320 moves to the right end of the first arc-shaped sliding groove 301. Then, under the action of the pulling force, the moving frame 300 continues to slide, at this time, the sliding rod 320 moves from the right end of the support sliding groove 311 to the left end of the support sliding groove 311, and the moving frame 300 can reach the maximum extension position (shown in FIG. 15).

[0084] The movement mode of the sliding rod 320 relative to the second arc-shaped sliding groove 302 can refer to the movement mode of the sliding rod 320 relative to the first arc-shaped sliding groove 301, which will not be described here.

[0085] Please refer to FIG. 17. In order to make the sliding rod 320 move relative to the first arc-shaped sliding groove 301 first, and then move relative to the support sliding groove 311, the moving frame 300 further comprises two limiting members 3111, which are oppositely arranged on the support sliding groove 311. The limiting member 3111 can be understood as a limiting protruding structure, which can abut against the sliding rod 320 under the condition that the pulling force on the moving frame 300 is small, so as to limit the sliding rod 320 at the right end of the support sliding groove 311. After the sliding rod 320 moves to the right end of the first arc-shaped sliding groove 301, the pulling force on the moving frame 300 is increased, the sliding rod 320 can be released from the constraint of the two limiting members 3111, the sliding rod 320 moves from the right end of the support sliding groove 311 to the left end of the support sliding groove 311, and the moving frame 300 can reach the maximum extension position.

[0086] It should be noted that in order to facilitate the chair back 1100 to be more smooth during movement, the safety seat moving device further comprises a plurality of rollers (not shown in the figure), which 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 provided with one roller, which is used to rollingly contact the rotating disc 200.

[0087] In some embodiments, in order to facilitate the moving frame 300 to be kept in the initial position or the maximum extension position, please refer to FIG. 18 and FIG. 19, the rotating disc 200 is further provided with at least one limiting sliding groove 304, the end of the first arc-shaped sliding groove 301 is communicated with the limiting sliding groove 304, and the moving frame 300 is slidably matched with the first arc-shaped sliding groove 301 and the limiting sliding groove 304. Among them, the height of the end of the limiting sliding groove 304 away from the first arc-shaped sliding groove 301 is lower than the height of the connection between the first arc-shaped sliding groove 301 and the limiting sliding groove 304.

[0088] Specifically, the left end of the first arc-shaped sliding groove 301 and the right end of the first arc-shaped sliding groove 301 are both communicated with one limiting sliding groove 304. Since the height of the end of the limiting sliding groove 304 away from the first arc-shaped sliding groove 301 is lower than the height of the connection between the first arc-shaped sliding groove 301 and the limiting sliding groove 304, as shown in FIG. 18, the sliding rod 320 can stay in the limiting sliding groove 304 communicated with the left end of the first arc-shaped sliding groove 301 under the action of gravity in the initial state. Under the action of tension, the moving frame 300 moves into the limiting sliding groove 304 communicated with the right end of the first arc-shaped sliding groove 301, and the sliding rod 320 can stay in the limiting sliding groove 304 communicated with the right end of the first arc-shaped sliding groove 301 under the action of gravity. At this time, the moving frame 300 is in the maximum extension position (as shown in FIG. 19), and at this time, the chair back 1100 can be understood as being in a suspended and stopped state.

[0089] Of course, in some embodiments, the left end of the first arc-shaped sliding groove 301 or the right end of the first arc-shaped sliding groove 301 can also be communicated with one limiting sliding groove 304.

[0090] The limiting sliding groove 304 and the first arc-shaped sliding groove 301 are both arc-shaped structures, the arc-shaped track of the limiting sliding groove 304 and the arc-shaped track of the first arc-shaped sliding groove 301 can be tangent, at the same time, the center of the limiting sliding groove 304 is located below the limiting sliding groove 304, and the center of the first arc-shaped sliding groove 301 can be located above the limiting sliding groove 304.

[0091] Of course, the two ends of the second arc-shaped sliding groove 302 are also communicated with one limiting sliding groove 304, which can be specifically referred to the above-mentioned communication state of the limiting sliding groove 304 and the first arc-shaped sliding groove 301, and details are not repeated here.

[0092] Please refer to Figure 20 and combine Figure 5-7, in some embodiments, in order to facilitate the locking of the chair back 1100 extension position after the chair back 1100 rotates and slides out first, and at the same time, it can also adjust a plurality of chair back 1100 extension positions, the safety seat moving device also includes a resilient member 400, which can be understood as a spring, the support plate 310 of the moving frame 300 is provided with a plurality of gear grooves 303, and the resilient member 400 is arranged in the rotating disc 200, wherein the resilient member 400 is used for elastically abutting any gear groove 303 when the moving frame 300 slides to a first preset position relative to the first arc-shaped sliding groove 301.

[0093] The plurality of gear grooves 303 are sequentially distributed from left to right, and when the end of the spring abuts the leftmost gear groove 303, the resilient member 400 can lock the extension state of the chair back 1100, and the first preset position can be understood as the maximum extension position of the moving frame 300.

[0094] Of course, in other cases, when the moving frame 300 needs to be in a different extension position during the right movement of the moving frame 300, the first preset position can also be understood as the position of the end of the spring when it abuts in other corresponding gear grooves 303 (which can be defined by adjacent protrusions, and the end of the spring will elastically deform when it abuts and passes through the protrusions), the end of the spring abuts in other corresponding gear grooves 303 to lock the extension state of the chair back 1100.

[0095] Please refer to Figure 21 and combine Figure 5-7, in some embodiments, other ways can also be used to lock the chair back 1100 extension position, specifically, the rotating disc 200 has a first limiting protrusion 210, and the support plate 310 of the moving frame 300 has a second limiting protrusion 330, wherein the second limiting protrusion 330 is used to abut the first limiting protrusion 210 when the moving frame 300 slides to a second preset position relative to the first arc-shaped sliding groove 301.

[0096] The second preset position here can be understood as the position of the moving frame 300 when the sliding rod 320 slides to the right end of the first arc-shaped sliding groove 301 as shown in Figure 7, during the sliding of the sliding rod 320 to the right end of the first arc-shaped sliding groove 301, the second limiting protrusion 330 slides relative to the first limiting protrusion 210 and passes through the first limiting protrusion 210, under the action of the gravity of the chair back 1100 and the moving frame 300, the second limiting protrusion 330 abuts at the first limiting protrusion 210 to lock the extension state of the chair back 1100.

[0097] In order to also achieve the adjustment of the plurality of chair back 1100 extension positions, the number of second limiting protrusions 330 can be multiple, and the multiple second limiting protrusions 330 can be sequentially distributed along the direction in which the chair back 1100 moves to the right. When the moving frame 300 needs to be in different extension positions during the movement to the right, different second limiting protrusions 330 can be abutted at the first limiting protrusion 210 to lock the different extension 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 the different second limiting protrusions 330 are abutted at the first limiting protrusion 210 to lock the different extension states of the chair back 1100.

[0099] In summary, the safety seat moving device includes a base 100, a rotating disc 200, and a moving frame 300. The rotating disc 200 is rotatably installed on the base 100, and the rotating disc 200 is provided with a first arc-shaped sliding groove 301. The moving frame 300 is connected with the rotating disc 200, and the moving frame 300 is slidably matched with the first arc-shaped sliding groove 301. The moving frame 300 is used to connect the chair back 1100.

[0100] In the process of sliding relative to the first arc-shaped sliding groove 301, the height of the moving frame 300 changes. When an adult needs to take out or place a child, after the rotating disc 200 is rotated relative to the base 100, the chair back 1100 connected with the moving frame 300 can be directed towards the door. Then, the moving frame 300 slides relative to the first arc-shaped sliding groove 301 to approach the door. In this process, the height of the moving frame 300 changes, and thus the height of the center of gravity of the chair back 1100 can change. This improves the playability and interest of the child safety seat 1000, better fits the playful nature of children, increases the acceptance of children to the child safety seat 1000, and reduces the fear of children to the child safety seat 1000.
