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

[0041] It should be noted that like reference numerals denote like items in the following drawings, and therefore, once an item is defined in one drawing, it will not be further defined or explained in the subsequent drawings.

[0042] like Figure 1 As shown, a child safety carrier 100 for vehicles includes a child safety carrier 102 for infants to sit or lie down, 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 young children. It not only functions as a car safety seat in the car, but also as a small cradle for babies, making it convenient for use at home or on the go. The carrier can be fixed to the car seat and is easy to carry after leaving the vehicle. It can even be installed on a stroller.

[0043] The rotatable base 101 is the core component of the device, allowing the carrier to rotate on the base to adapt to different usage scenarios and vehicle seat layouts. This technical means provides additional convenience and flexibility, allowing parents to easily adjust the carrier's orientation as needed, including forward-facing and rear-facing.

[0044] Specifically, the rotatable base 101 of the vehicle-mounted child safety carrier comprises a housing 10 and a support device 20. The housing 10 comprises a base 11 and a bottom cover 12. After assembly, the bottom cover 12 overlies the base 11, forming a sturdy foundation. The bottom cover 12 is connected to the base 11 via a set of screws, ensuring stability and forming an internal cavity h between the two, providing space for securing and supporting the device.

[0045] A circular hole h1 is provided in 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. Each of these fasteners is an arc-shaped segment with an L-shaped cross-section, consisting of an outer plate portion 01 and an inner, downwardly extending curved flange 02. This technical approach enhances the fasteners' grip and stability, achieving a locking connection between the circular chassis and the bottom cover 12. This hooking mechanism, similar to multiple anchor points, provides multiple fixing points and increases the stability of the connection.

[0046] The support device 20 comprises a circular base 21 and a pair of support frames 22 mounted on the upper side of the base 21. Each support frame 22 has a locking end v at each end, which is used to lock and release the two connecting rods 103 on the lower side of the basket 102. The bottom of the circular base 21 is equipped with multiple hooks n distributed around the circumference. These hooks connect to the circular holes h1 on the bottom cover 12 via a rotating snap-fit ​​mechanism, achieving a rotational locking function for the base.

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

[0048] The circular hole h1 has a retaining ring c on its underside and multiple inward-extending stoppers b1 on its upper side, forming an annular groove d. The outer edge of the circular base 21 is provided with a notch v that mates with the stoppers b1, allowing the outer edge of the circular base 21 to enter and rotate within the annular groove d. A locking block v1 is installed at the position of the notch v, which is blocked by the side of the stoppers b1, preventing the circular base 21 from dislodging from the annular groove d. This technical measure ensures the stability and safety of the base during rotation.

[0049] The shell bottom 11 has a concave-convex structure, and the height difference between its outer bottom surface s1 and the inner surface s2 is greater than 5CM. The concave-convex structure technical means of the shell bottom 11 makes the height difference between the outer bottom surface s1 and the inner surface s2 greater than 5CM. This technical means 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 driving.

[0051] A mounting bracket 40 is welded to the rear end of the FIX assembly 13. Connecting ears m21 are provided on either side of the rear fixing member m2, which is screwed to the mounting bracket 40. This structural technique further strengthens the connection between the base and the vehicle seat, ensuring that the carrier will not separate from the base in the event of a collision.

[0052] Further, the lock 30 is installed on the front side of the bottom cover 12, including a lock tongue 31, a handle 32 and a spring 33. The lock tongue 31 is arranged at the front end of the handle 32, and the spring 33 is connected between the handle 32 and the bottom cover 12. The front side and the rear side of the circular base plate 21 are respectively provided with a lock hole 34. This technical means makes the locking and unlocking operation of the base simple and convenient, and the spring 33 provides additional assistance to ensure that the lock is not easily accidentally unlocked when impacted, improving the safety of use.

[0053] Preferably, the circular base plate 21 includes a disc body 211 and an annular edge 212 arranged at the upper side of the disc body 211, and the disc body 211 protrudes downward from the annular edge 212. A positioning hole g2 is arranged at the center of the disc body 211, the disc body 211 extends into the inner cavity h inside the metal fixing member m, and a plurality of hook portions n extend outward from the outer edge of the disc body 211 and are hooked with the metal fixing member m, thereby achieving the locking of the circular base plate 21 and the bottom cover 12.

[0054] Further, the FIX assembly 13 is fixed in the groove 16 of the shell bottom 11, and the upper surface of the FIX assembly 13 does not exceed the inner surface s2 of the shell bottom 11. This technical means ensures the close connection of the FIX assembly with the vehicle seat, while maintaining the neat appearance of the base.

[0055] In actual use, the locking process includes: first, the parent holds the handle 32 located on the front side of the bottom cover 12, and moves the lock tongue 31 at the front end by moving the handle 32, so that the lock tongue 31 moves from the unlocked position to the locked position and is inserted into the lock hole 34 on the front side of the circular base plate 21, thereby stably locking the basket 102 on the base 101. The spring 33 is connected between the handle 32 and the bottom cover 12 to provide a restoring force for the handle, ensuring that the handle and the lock tongue can return to the original position after the handle is released, thereby enhancing the stability of the base during vehicle driving. In the locked state, the support device 20 is fixed and not allowed to rotate.

[0056] In the unlocking process, the parent first holds and pulls the handle 32, so that the lock tongue 31 is pulled out of the lock hole 34, which allows the support device 20 to rotate. At this time, the parent can rotate the circular base plate 21 to change the direction of the basket 102, whether forward or backward, to adapt to different use requirements. The rotation capability of the support device 20 makes the switching of the basket direction simple and fast.

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

[0058] In summary, the above technical solution provides a safe and convenient vehicle-mounted child safety basket system. The core of the system lies in the rotatable base 101, which allows the basket 102 to rotate on the base, preferably including two states facing forward and backward to adapt to different usage scenarios and vehicle seat layouts, thereby enhancing the flexibility of use. The sturdy structure of the shell 10, the circumferential distribution of the metal fixings m, and the locking mechanism of the support device 20 jointly ensure the stability and safety of the basket during use. In addition, the design of the rotating clamping structure and the locking block v1 ensures that the base maintains rotational flexibility while also ensuring the stability of the connection, thereby improving safety during vehicle driving, especially in the event of an accidental collision.

[0059] Overall, this innovative solution achieves the versatility and high stability of a child safety carrier for vehicles. It not only meets parents' needs for infant and child safety while also providing convenient operation and a comfortable ride, making the product more user-friendly and practical while ensuring safety.
