Abstract
Description
A lateral shifting seat positioning structure and a child safety seat Technical Field
[0001] This utility model relates to the field of automotive safety products technology, specifically to a lateral shifting seat positioning structure and a child safety seat. Background Technology
[0002] To improve the ease of use of child safety seats, a side-sliding design has been adopted on the market. This means that when getting in and out of the car, the seat back faces the door and then slides towards it, making it easier for parents to safely get their children in and out of the car. However, because the door opening space varies between different car models, the distance of the side-sliding is often limited. Existing technologies still have limited applicability to different car models and cannot fully meet the diverse needs of users. Utility Model Content
[0003] To address at least one of the aforementioned problems, this utility model first provides a lateral sliding seat positioning structure, including a base, a backrest, and a rotating and sliding assembly disposed between the base and the backrest. The rotating and sliding assembly includes a rotating disk and a sliding frame adapted to be slidably connected to the rotating disk. The rotating disk is rotatably connected to the base, and the sliding frame is connected to the backrest. The sliding frame has a limiting protrusion and multiple position protrusions, and the rotating disk has a positioning protrusion. Under normal use, the limiting protrusion and the positioning protrusion engage to prevent the sliding frame from sliding relative to the rotating disk. When it is necessary to place a child towards the car door, the sliding frame is pushed to disengage the positioning protrusion from the limiting protrusion, and the sliding frame slides towards the car door relative to the rotating disk until one of the multiple position protrusions engages with the positioning protrusion to fix the position between the backrest and the base.
[0004] Optionally, the positioning protrusion is made of plastic.
[0005] Optionally, the positioning protrusion is a triangular protrusion, the limiting protrusion is an inverted triangular protrusion, and the plurality of the gear protrusions are arranged adjacently and form a wave-shaped structure as a whole.
[0006] Optionally, the number of gear shift protrusions is three, and the three gear shift protrusions are arranged at intervals along the sliding direction of the sliding frame relative to the rotating disk.
[0007] Optionally, the sliding frame is further provided with a limiting protrusion for limiting the extreme position of the positioning protrusion, and both the limiting protrusion and the stop protrusion are located within the limiting protrusion.
[0008] Optionally, the sliding bracket is provided with a handle on its side. When facing the car door, the user can pull the handle to slide the sliding bracket relative to the rotating disk to adjust it to the required position.
[0009] Optionally, the handles are provided on both sides of the sliding frame.
[0010] Optionally, the base has notches on both the left and right sides, and when it is necessary to take a child out of the car door, the handles on both sides are respectively set to correspond to the notches on both sides.
[0011] Optionally, the handle is in the shape of an arc segment, and under normal use, the arc segment is coaxially arranged with the rotating disk.
[0012] Compared to existing technologies, the lateral sliding seat positioning structure in this invention, through the combination of a rotating plate and a sliding frame, allows the seat to be adjusted to the optimal position by rotation and translation, making it suitable for different vehicle door spaces and cabin structures, thus providing wider applicability. By setting multiple adjustable protrusions, users can easily adjust the seat position according to actual conditions, achieving multiple translation distances, adapting to the opening space of different vehicle models, facilitating children's entry and exit, and the structure is simple and reliable.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0024] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.
[0025] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
[0026] This utility model embodiment provides a lateral translational seat positioning structure, as shown in Figures 1 to 6. It includes a base 1, a backrest 2, and a rotational translational assembly 3 disposed between the base 1 and the backrest 2. The rotational translational assembly 3 includes a rotating disk 31 and a sliding frame 32 adapted to be slidably connected to the rotating disk 31. The rotating disk 31 is rotatably connected to the base 1, and the sliding frame 32 is connected to the backrest 2. The sliding frame 32 is provided with a limiting protrusion 321 and multiple position protrusions 322. The rotating disk 31 is provided with a positioning protrusion 311. Under normal use, the limiting protrusion 321... 1. Engages with the positioning protrusion 311 to prevent the sliding frame 32 from sliding relative to the rotating disk 31. The limiting protrusion 321 is used to lock the sliding frame 32 in the normal state, thereby maintaining the stability of the seat in the current set position. When it is necessary to take a child out of the car door, push the sliding frame 32 to disengage the positioning protrusion 311 from the limiting protrusion 321, and the sliding frame 32 slides relative to the rotating disk 31 toward the car door until one of the multiple position protrusions 322 engages with the positioning protrusion 311 to fix the position between the seat back 2 and the base 1.
[0027] Multiple position protrusions 322 are designed at different positions along the sliding path, and can engage with the positioning protrusions 311 on the rotating disk 31. The sliding frame 32 can move laterally on the rotating disk 31. The sliding frame 32 is provided with multiple position protrusions 322 to provide different position selections. When the sliding frame 32 is pushed, these position protrusions 322 can engage with the positioning protrusions 311 on the rotating disk 31 to fix the backrest 2 in different positions. When the positioning protrusions 311 and the limiting protrusions 321 engage with each other, the sliding frame 32 can be prevented from sliding relative to the rotating disk 31, ensuring the stability of the seat.
[0028] When it is necessary to take a child out of the car towards the door, first rotate the sliding bracket 32 relative to the rotating plate 31 so that the seat back 2 faces the door. Then push the sliding bracket 32 towards the door so that the limiting protrusion 321 and the positioning protrusion 311 disengage from each other, thereby unlocking the translation function of the sliding bracket 32. Then slide the sliding bracket 32 relative to the rotating plate 31 towards the door until one of the gear shift protrusion 322 engages with the positioning protrusion 311 of the rotating plate 31, and the position of the seat back 2 is locked. The user can adjust the sliding distance of the sliding bracket 32 as needed so that the seat back 2 is accurately positioned in the ideal position.
[0029] The lateral sliding seat positioning structure in this embodiment, through the combination of the rotating disk 31 and the sliding frame 32, allows the seat to be adjusted to the optimal position by rotation and translation, which is suitable for the door space and cabin structure of different car models, providing wider applicability; by setting multiple gear protrusions 322, users can easily adjust the position of the seat according to the actual situation, realizing multiple gear translation distances, which can adapt to the door opening space of different car models, making it convenient for children to get in and out of the car, and the structure is simple and reliable.
[0030] Optionally, as shown in Figures 4, 5, and 6, the positioning protrusion 311 is made of plastic. The positioning protrusion 311 deforms and springs back as it slides over the limiting protrusion 321 or the shift protrusion 322, resulting in low manufacturing cost and a simple structure. During seat adjustment, when the sliding frame 32 slides along the rotating disk 31, the positioning protrusion 311 slides over the limiting protrusion 321 or multiple shift protrusions 322. Due to the flexible nature of the plastic positioning protrusion 311, it can slightly deform to adapt to different protrusion shapes when it comes into contact with other protrusion surfaces. As the sliding frame 32 continues to slide, after the positioning protrusion 311 slides past the top of the limiting protrusion 321 or the shift protrusion 322, it quickly springs back under the elasticity of the material, achieving engagement and locking the seat back 2.
[0031] Optionally, as shown in Figure 5, the positioning protrusion 311 is a triangular protrusion, the limiting protrusion 321 is an inverted triangular protrusion, and the multiple gear protrusions 322 are arranged adjacently and form a wave-shaped structure. 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 allows only a small force to be applied when disengaging from the limiting protrusion 321, while the wide surface at the bottom provides a stable locking effect when engaged. The tip of the limiting protrusion 321 faces the rotating disk 31, and the inverted triangular design allows it to provide a precise locking effect when engaged with the triangular positioning protrusion 311. The wave-shaped structure formed by the multiple gear protrusions 322 provides multiple selectable gear positions.
[0032] Optionally, as shown in Figure 5, the number of gear position protrusions 322 is three. The three gear position 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 position protrusions 322 allow the user to select and fix between three different positions, which can ensure the ease of operation and meet the user's actual needs.
[0033] Optionally, as shown in Figure 4, the sliding frame 32 is further provided with a limiting ring 323 for limiting the extreme position of the positioning protrusion 311. Both the limiting protrusion 321 and the stop protrusion 322 are located within the limiting ring 323. The limiting ring 323 is an annular structure disposed on the sliding frame 32, surrounding the positioning protrusion 311 and the stop protrusion 322. The limiting 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 does not exceed the predetermined sliding range and preventing the sliding frame 32 from detaching from the rotating disk 31.
[0034] Optionally, as shown in Figures 3 and 4, the sliding frame 32 is provided with a handle 324 on its side. When facing the car door, the user can pull the handle 324 to slide the sliding frame 32 relative to the rotating disk 31 to adjust it to the required position. The design of the handle 324 allows the user to easily adjust the position of the sliding frame 32. The handle 324 is designed with a shape that is easy for the user to operate (such as an arc shape, strip shape, etc.), which meets the ergonomic grip requirements and can provide the user with a good feel and operating experience. In normal use, the handle 324 is hidden in the base 1, which not only maintains the aesthetics of the overall appearance, but also improves the structural connection stability between the seat back 2 and the base 1.
[0035] Optionally, as shown in Figures 3 and 4, the sliding frame 32 is provided with handles 324 on both sides; the dual-side layout ensures that no matter the installation direction of the seat, the user can easily find and pull the handles 324 on one side to adjust the position of the seat. That is, the backrest 2 can be easily pulled to move laterally when it is installed facing forward or backward, which has a wide range of applications.
[0036] Optionally, as shown in Figures 3 and 6, the base 1 has notches 11 on both the left and right sides. When it is necessary to take a child out of the car door, the handles 324 on both sides are respectively set to correspond to the notches 11 on both sides. The notches 11 are usually designed to be aligned or approximately aligned with the opening of the car door so that the sliding bracket 32 can slide towards the car door through the notches 11, ensuring that the seat is not obstructed when moving towards the car door.
[0037] Optionally, as shown in Figures 3 and 4, the handle 324 is an arc-shaped segment. Under normal use, the arc-shaped segment is coaxially arranged with the rotating disk 31, ensuring smooth docking of the handle 324 with the sliding frame 32 and the rotating disk 31, providing a consistent operating experience. The arc-shaped handle 324 partially surrounds the outer edge of the rotating disk 31, which not only conforms to ergonomics but also provides a comfortable grip. If the sliding frame 32 has two handles 324, the arc-shaped segments of both handles 324 are coaxially arranged with the rotating disk 31, ensuring the symmetry and stability of the seat during adjustment.
[0038] Another embodiment of the present invention provides a child safety seat, including the lateral translation seat positioning structure described above.
[0039] The child safety seat in this embodiment, through the combination of the rotating disc 31 and the sliding frame 32, allows the seat to be adjusted to the optimal position by rotation and translation, making it suitable for the door space and cabin structure of different vehicle models, thus providing wider applicability; by setting multiple position protrusions 322, users can easily adjust the position of the seat according to the actual situation, achieving multiple translation distances, which can adapt to the door opening space of different vehicle models, making it convenient for children to get in and out of the vehicle, and the structure is simple and reliable.
[0040] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
