[0023] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", etc. is based on the orientation or positional relationship during the normal use of the product.

[0025] The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

[0026] An embodiment of the present utility model provides a lateral translation seat positioning structure. As shown in combination with Figures 1 to 6 the figure, it includes a base 1, a backrest 2, and a rotary and translation assembly 3 disposed between the base 1 and the backrest 2. The rotary and translation assembly 3 includes a rotary disk 31 and a sliding frame 32 adapted to be slidably connected to the rotary disk 31. The rotary disk 31 is rotatably connected to the base 1, the sliding frame 32 is connected to the backrest 2, the sliding frame 32 is provided with a limiting protrusion 321 and a plurality of gear protrusions 322, and the rotary disk 31 is provided with a positioning protrusion 311. In the normal use state, the limiting protrusion 321 is engaged with the positioning protrusion 311 to prevent the sliding frame 32 from sliding relative to the rotary disk 31. The limiting protrusion 321 is used to lock the sliding frame 32 in the normal state, so as to maintain the stability of the seat in the current set position. When it is necessary to pick up and place a child towards the door, the sliding frame 32 is pushed to disengage the positioning protrusion 311 from the limiting protrusion 321, and the sliding frame 32 slides relative to the rotary disk 31 towards the door until one of the plurality of gear protrusions 322 is engaged with the positioning protrusion 311 to fix the position between the backrest 2 and the base 1.

[0027] Among them, multiple gear protrusions 322 are designed at different positions on the sliding path and can be engaged and clamped with the positioning protrusions 311 on the rotating disk 31. The sliding frame 32 can laterally translate on the rotating disk 31. Multiple gear protrusions 322 are provided on the sliding frame 32 to provide choices of different positions. When the sliding frame 32 is pushed, these gear protrusions 322 can be engaged and clamped with the positioning protrusions 311 on the rotating disk 31 to achieve the purpose of fixing the backrest 2 at different extended positions. When the positioning protrusions 311 are engaged and clamped with the limit protrusions 321, the sliding of the sliding frame 32 relative to the rotating disk 31 can be prevented, ensuring the stability of the seat.

[0028] When it is necessary to pick up and place a child towards the door direction, first rotate the sliding frame 32 relative to the rotating disk 31 so that the backrest 2 faces the door, and then push the sliding frame 32 towards the door, so that the limit protrusions 321 are disengaged from the positioning protrusions 311, thereby unlocking the translation function of the sliding frame 32. Then slide the sliding frame 32 relative to the rotating disk 31 towards the door direction until one of the gear protrusions 322 is engaged and clamped with the positioning protrusions 311 on the rotating disk 31, and the position of the backrest 2 is locked. The user can adjust the sliding distance of the sliding frame 32 according to needs so that the backrest 2 is accurately positioned at an ideal position.

[0029] In the lateral translation seat positioning structure in this embodiment, through the combination of the rotating disk 31 and the sliding frame 32, the seat can be adjusted to the best position through rotation and translation, which is applicable to the door spaces and carriage structures of different vehicle models, providing a wider range of applicability. By setting multiple gear protrusions 322, the user can easily adjust the position of the seat according to the actual situation, realize multi-gear translation distances, can adapt to the opening spaces of different vehicle models, facilitate the operation of children getting on and off the vehicle, and has a simple and reliable structure.

[0030] Optionally, in combination with Figure 4 、 Figure 5 、 Figure 6 As shown, the material of the positioning protrusions 311 is plastic. By using the fact that the positioning protrusions 311 can be deformed and rebound when sliding over the limit protrusions 321 or the gear protrusions 322, the manufacturing cost is low and the structure is simple. During the seat adjustment process, when the sliding frame 32 slides along the rotating disk 31, the positioning protrusions 311 slide over the limit protrusions 321 or multiple gear protrusions 322. Due to the flexible characteristics of the plastic positioning protrusions 311, when they come into contact with the surfaces of other protrusions, they can be slightly deformed to adapt to different protrusion shapes. When the sliding frame 32 continues to slide and the positioning protrusions 311 slide over the tops of the limit protrusions 321 or the gear protrusions 322, they quickly rebound under the elastic action of the material to achieve clamping and complete the locking of the backrest 2.

[0031] Optionally, in combination with Figure 5As shown, the positioning protrusion 311 is a triangular protrusion, the limiting protrusion 321 is an inverted triangular protrusion, and multiple gear protrusions 322 are arranged adjacent to each other and form a wavy structure as a whole. The tip of the positioning protrusion 311 faces the sliding frame 32, and the bottom is fixedly connected to the rotating disk 31. The sharp structure enables a relatively small force to be applied when disengaging from the limiting protrusion 321, while the wide surface at the bottom can provide a stable locking effect during meshing and clamping; the tip of the limiting protrusion 321 faces the rotating disk 31, and the inverted triangular design enables it to provide an accurate locking effect when meshing and clamping with the triangular positioning protrusion 311; the design of the wavy structure formed by multiple gear protrusions 322 can provide multiple selectable gear positions.

[0032] Optionally, in combination with Figure 5 As shown, the number of the gear protrusions 322 is three, and the three gear protrusions 322 are arranged at intervals along the sliding direction of the sliding frame 32 relative to the rotating disk 31, that is, they are arranged at intervals on the sliding path; the three gear protrusions 322 enable the user to select and fix among three different positions, which can not only ensure the simplicity of operation but also meet the actual needs of the user.

[0033] Optionally, in combination with Figure 4 As shown, the sliding frame 32 is further provided with a limiting convex ring 323 for limiting the extreme position of the positioning protrusion 311, and both the limiting protrusion 321 and the gear protrusion 322 are located within the limiting convex ring 323. The limiting convex ring 323 is an annular structure arranged on the sliding frame 32, surrounding the positioning protrusion 311 and the gear protrusion 322. The limiting convex ring 323 is used to limit the extreme sliding position of the sliding frame 32 relative to the rotating disk 31, ensuring that the sliding frame 32 will not exceed the predetermined sliding range and preventing the sliding frame 32 from disengaging from the rotating disk 31.

[0034] Optionally, in combination with Figure 3 、 Figure 4 As shown, a handle 324 is provided on the side surface of the sliding frame 32. When facing the car door, the user drives the sliding frame 32 to slide relative to the rotating disk 31 by pulling the handle 324 to adjust to the required position distance. The design of the handle 324 enables the user to easily adjust the position of the sliding frame 32; the handle 324 is designed in a shape convenient for the user to operate (such as an arc segment shape, a strip shape, etc.), meeting the ergonomic gripping requirements and providing the user with a good hand feeling and operation experience; in the normal use state, the handle 324 is hidden in the base 1, which not only maintains the aesthetic appearance of the whole but also improves the structural connection stability between the backrest 2 and the base 1.

[0035] Optionally, in combination with Figure 3 、 Figure 4As shown, handle 324 is provided on both sides of the sliding carriage 32; the bilateral layout ensures that no matter how the seat is installed, users can conveniently find and pull the handle 324 on one side to adjust the position of the seat, that is, the backrest 2 can be conveniently pulled for lateral translation whether the backrest 2 is installed forward or backward, with a large scope of application.

[0036] Optionally, in combination with Figure 3 , Figure 6 As shown, notches 11 are provided on both the left and right sides of the base 1. When it is necessary to pick up and place a child facing the car door, the handles 324 on both sides are respectively arranged corresponding to the notches 11 on both sides. The notches 11 are usually designed to be aligned or approximately aligned with the opening position of the car door, so that the sliding carriage 32 can translate through the notches 11 towards the car door, ensuring that the seat is unobstructed when moving towards the car door.

[0037] Optionally, in combination with Figure 3 , Figure 4 As shown, the handle 324 is in the shape of an arc segment. In the normal use state, the arc segment shape is coaxially arranged with the rotating disk 31, ensuring the smooth docking of the handle 324 with the sliding carriage 32 and the rotating disk 31, providing a consistent operation experience; the shape of the handle 324 is an arc segment, partially surrounding the outer edge of the rotating disk 31, which not only conforms to ergonomics but also provides a comfortable gripping experience; if there are two handles 324 on the sliding carriage 32, the arc segment shapes of the two handles 324 are both coaxially arranged with the rotating disk 31, ensuring the symmetry and stability of the seat during adjustment.

[0038] Another embodiment of the present utility model provides a child safety seat, including the lateral translation seat positioning structure as described above.

[0039] In the child safety seat of this embodiment, through the combination of the rotating disk 31 and the sliding carriage 32, the seat can be adjusted to the optimal position by rotation and translation, which is applicable to the door space and carriage structure of different vehicle models, providing a wider applicability; by setting multiple gear protrusions 322, users can easily adjust the position of the seat according to the actual situation, realizing a multi-gear translation distance, which can adapt to the opening space of different vehicle models, facilitating the operation of children getting on and off the vehicle, and the structure is simple and reliable.
