[0040] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of the invention.

[0041] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0042] like Figure 1 As shown, the car child safety carrier 100 includes a child safety carrier 102 for infants and toddlers to sit or lie on, and a rotatable base 101. The child safety carrier 102 is rotatably connected to the base. This is a travel safety device specifically designed for infants and toddlers. It can be used not only as a car seat in a car, but also as a baby cradle, making it convenient for use at home or when traveling. The carrier can be fixed to the car seat, making it easy to carry after getting out of the car, and can even be installed on a stroller.

[0043] The rotatable base 101 is the core component of the device, allowing the baby carrier to rotate on the base to adapt to different usage scenarios and vehicle seating layouts. This technology provides additional convenience and flexibility, enabling parents to easily adjust the orientation of the baby carrier as needed, including forward or backward orientation.

[0044] Specifically, the rotatable base 101 of the car child safety carrier includes a housing 10 and a support device 20. The housing 10 consists of a bottom 11 and a bottom cover 12. After assembly, the bottom cover 12 covers the bottom 11, forming a sturdy base. The bottom cover 12 and the bottom 11 are connected by a set of screws to ensure the stability of the connection, while forming an inner cavity h between them to provide space for fixing and supporting the device.

[0045] A circular hole h1 is provided on the bottom cover 12, communicating with the inner cavity h. Multiple metal fasteners m are distributed circumferentially within the inner cavity h below the circular hole h1. These metal fasteners m include a rear fastener m2 and two front fasteners m1, all of which are arc-shaped segments with an L-shaped cross-section, including an outer plate portion 01 and an inner arc-shaped protruding edge 02 extending downwards. This technique enhances the gripping force and stability of the fasteners. It achieves locking between the circular chassis and the bottom cover 12; this interlocking mechanism is similar to multiple anchor points, providing multiple fixing points and increasing the stability of the connection.

[0046] The support device 20 includes a circular base 21 and a pair of support frames 22, which are mounted on the upper side of the circular base 21. Each support frame 22 has a locking end v at both ends for locking and releasing the two connecting rods 103 on the lower side of the basket 102. The bottom of the circular base 21 has multiple hooks n distributed circumferentially, which are connected to the circular holes h1 on the bottom cover 12 through a rotating snap-fit ​​structure to realize the rotation locking function of the base.

[0047] It should be noted that the rotating snap-fit ​​structure between the circular base 21 and the bottom cover 12, combined with the locking block v1 at the notch v position, provides a connection method that can be both rotated and locked. This technology ensures the stability of the connection while maintaining the flexibility of the base.

[0048] A support ring c is provided on the lower side of the hole wall b of the circular hole h1, and multiple inwardly extending limiting parts b1 are provided on the upper side, forming an annular groove d between them. The outer edge of the circular base 21 has a notch v that matches the limiting parts b1, allowing the outer edge of the circular base 21 to enter the annular groove d and rotate within it. A locking block v1 is installed at the notch v position, which can be blocked by the side of the limiting parts b1 to prevent the circular base 21 from disengaging from the annular groove d. This technical means ensures the stability and safety of the base during rotation.

[0049] The bottom of the shell 11 has a concave-convex structure, and the height difference between its outer bottom surface s1 and inner surface s2 is greater than 5 cm. The concave-convex structure of the bottom of the shell 11 makes the height difference between the outer bottom surface s1 and inner surface s2 greater than 5 cm. This technology increases the contact area between the base and the vehicle seat, thereby improving the stability of the base.

[0050] A positioning shaft g1 is provided at the center of the inner surface of the shell bottom 11, which cooperates with the positioning hole g2 at the bottom of the circular chassis 21 to ensure the accurate positioning of the circular chassis; this precise cooperation mechanism provides a stable support for the basket and reduces shaking during vehicle operation.

[0051] A mounting bracket 40 is welded to the rear end of the FIX assembly 13. Connecting ears m21 are provided on both sides of the rear fixing piece m2, which are connected to the mounting bracket 40 by screws. This structural technology further enhances the connection stability between the base and the vehicle seat, ensuring that the basket will not detach from the base in the event of a vehicle collision.

[0052] Furthermore, the lock 30 is installed on the front side of the base cover 12, including a latch 31, a handle 32, and a spring 33. The latch 31 is located at the front end of the handle 32, and the spring 33 is connected to the handle 32 and the base cover 12. Lock holes 34 are respectively provided on the front and rear sides of the circular base 21. This technology makes locking and unlocking the base simple and convenient, while the spring 33 provides additional assistance to ensure that the lock is not easily unlocked by accident when impacted, thus improving safety.

[0053] Preferably, the circular base 21 includes a circular body 211 and an annular edge 212. The annular edge 212 is located on the upper side of the circular body 211, and the circular body 211 protrudes downward from the annular edge 212. A positioning hole g2 is located at the center of the circular body 211. The circular body 211 extends into the inner cavity h inside the metal fastener m. Multiple hooks n extend out from the outer edge of the circular body 211 and hook with the metal fastener m to lock the circular base 21 to the bottom cover 12.

[0054] Furthermore, the FIX assembly 13 is secured within the groove 16 of the housing base 11, and the upper surface of the FIX assembly 13 does not exceed the inner surface s2 of the housing base 11. This technique ensures a tight connection between the FIX assembly and the vehicle seat while maintaining a clean appearance of the base.

[0055] In actual use, the locking process includes: the parent first grasps the handle 32 located on the front side of the bottom cover 12. The movement of the handle 32 moves the locking tongue 31 from the unlocked position to the locked position, inserting it into the locking hole 34 on the front side of the circular base 21, thus stably locking the basket 102 onto the base 101. A spring 33 connects the handle 32 and the bottom cover 12, providing a restoring force to the handle, ensuring that the handle and locking tongue return to their original positions after the handle is released, enhancing the stability of the base during vehicle movement. In the locked state, the support device 20 is fixed and cannot be rotated.

[0056] During the unlocking process, the parent first grasps and pulls the handle 32, causing the latch 31 to disengage from the lock hole 34. This action allows the support device 20 to rotate. At this time, the parent can rotate the circular base 21 to change the orientation of the basket 102, whether facing forward or backward, to adapt to different usage needs. The rotational capability of the support device 20 makes changing the orientation of the basket simple and quick.

[0057] Once the baby carrier 102 is rotated to the desired direction, the parent needs to realign the latch 31 with the new locking hole 34 and then push the handle 32 again to insert the latch 31 into the locking hole 34, thereby locking the support device 20 in the new position. In this way, the base 101 is locked again, ensuring that the baby carrier 102 is stable and safe in the new direction.

[0058] In summary, the above technical solution provides a safe and convenient in-vehicle child safety carrier system. Its core lies in the rotatable base 101, which allows the carrier 102 to rotate on the base, preferably in both forward and rearward orientations to adapt to different usage scenarios and vehicle seating layouts, enhancing its flexibility. The robust construction of the housing 10, the circumferential distribution of the metal fasteners m, and the locking mechanism of the support device 20 together ensure the stability and safety of the carrier during use. Furthermore, the design of the rotating snap-fit ​​structure and the locking block v1 ensures both rotational flexibility and connection stability, improving safety during vehicle operation, especially in the event of an accidental collision.

[0059] Overall, this technological solution achieves versatility and high stability in in-vehicle child safety carriers through its innovative technical means. It not only meets parents' needs for infant and toddler safety during travel but also provides convenient operation and a comfortable riding experience, making the product more user-friendly and practical while ensuring safety.
