[0030] like Figure 1 to Figure 6 The ISOFIX connection assembly of this embodiment includes a shell 10 and a core rod assembly 20.

[0031] The shell 10 includes a shell body 11 made of plastic, a first snap-fit ​​component 12 made of metal material and a second snap-fit ​​component 13 made of metal material. In this embodiment, the first snap-fit ​​component 12 and the second snap-fit ​​component 13 are both made of iron. The first snap-fit ​​component 12 is fixed to the shell body 11. The first snap-fit ​​component 12 is in the shape of an elongated strip and extends along the sliding direction of the core rod assembly 20. A plurality of first snap-fit ​​portions are arranged on the first snap-fit ​​component 12. The plurality of first snap-fit ​​portions are arranged at intervals along the length direction of the first snap-fit ​​component 12. Each first snap-fit ​​portion is a first through hole 121. The first through holes 121 pass through both surfaces of the first snap-fit ​​component 12.

[0032] The core rod assembly 20 is sleeved in the shell body 11, and one end of the core rod assembly 20 can extend out of the shell body 11. A second buckle portion is movably provided on the core rod assembly 20, and the second buckle portion has an unlocked state and a locked state. When the second buckle portion is in the unlocked state, the core rod assembly 20 can slide relative to the shell body 11 to extend or retract the core rod assembly 20 into the shell body 11; when the second buckle portion is in the locked state, the second buckle portion is engaged with one of the multiple first buckle portions so that the core rod assembly 20 can be fixed to the first buckle 12 after sliding relative to the shell body 11.

[0033] The second fastening part is the first bump 21. An adjusting part 22 for driving the first bump 21 to move so as to switch the first bump 21 between the unlocked state and the locked state is arranged on the core rod assembly 20. That is to say, when the adjusting part 22 is pressed, the adjusting part 22 can drive the first bump 21 to switch to the unlocked state. At this time, the first bump 21 retracts into the core rod assembly 20 so that the first bump 21 disengages from the first through hole 121, thereby enabling the core rod assembly 20 to slide relative to the housing 10 to adjust the length of the core rod assembly 20 extending out of the housing 10. After the length of the core rod assembly 20 extending out of the housing 10 is adjusted in place, the adjusting part 22 is released so that the first bump 21 switches to the locked state. At this time, the first bump 21 pops out of the core rod assembly 20, and the first bump 21 snaps into the first through hole 121 at the corresponding position, thereby positioning the core rod assembly 20 and the housing 10 relative to each other. At this time, the outer end of the core rod assembly 20 extending out of the housing 10 is connected to the ISOFIX interface on the vehicle to complete the installation and fixation of the safety seat on the vehicle.

[0034] A slot hole 117 is arranged on a side wall of the housing main body 11. The slot hole 117 extends along the sliding direction of the core rod assembly 20. The adjusting part 22 is located outside the housing main body 11, and the adjusting part 22 can be connected to the transmission mechanism in the core rod assembly 20 through the slot hole 117.

[0035] The cross section of the housing main body 11 is in a U-shaped structure. The first fastening part 12 covers the opening surface of the housing main body 11. The housing main body 11 and the first fastening part 12 enclose a channel for the core rod assembly 20 to slide. One end of this channel is closed and the other end is open. The core rod assembly 20 can extend out of the housing 10 through the open end of the channel.

[0036] The first fastening part 12 and the housing main body 11 are fixed by fasteners. Specifically, a first connection hole 122 is arranged on the first fastening part 12, and a second connection hole 114 is arranged on the housing main body 11. By passing a screw through the first connection hole 122 and then screwing it into the second connection hole 114, the first fastening part 12 can be fixed on the housing main body 11 by the screw, making the disassembly and assembly of the first fastening part 12 relatively convenient.

[0037] The second fastening part 13 is arranged on the housing main body 11. The second fastening part 13 is close to the open end of the channel formed by the housing main body 11 and the first fastening part 12 for the core rod assembly 20 to slide. A third fastening part is arranged on the second fastening part 13, and a fourth fastening part is arranged on the core rod assembly 20. The fourth fastening part is arranged at the bottom of the core rod assembly 20. When the core rod assembly 20 extends to the limit position of the housing main body 11, the third fastening part and the fourth fastening part are buckled together to prevent the core rod assembly 20 from detaching from the housing main body 11. In this way, it is possible to prevent the core rod assembly 20 from extending out of the housing 10 and the core rod assembly 20 from detaching from the housing 10.

[0038] The second fastener 13 is fastened and fixed on the housing body 11 , so that the second fastener 13 is easy to install.

[0039] The shell body 11 has a groove 111 for accommodating the core rod assembly 20, one end of the groove 111 is open and the other end is closed, one end of the shell body 11 is provided with a slot 112, the slot 112 is close to the open end of the groove 111 and is located below the groove 111, the bottom surface of the groove 111 is provided with a notch 1111 connected to the slot 112, the second clip 13 is inserted into the slot 112, and a snap-fitting portion 113 is provided in the slot 112, which is snap-fitted with the second clip 13 to prevent the second clip 13 from detaching from the shell body 11, so that when the core rod assembly 20 is extended to the extreme position of the shell body 11, the fourth snap-fitting portion on the core rod assembly 20 and the third snap-fitting portion on the second snap-fit ​​are snap-fitted with each other to prevent the core rod assembly 20 from detaching from the shell body 11.

[0040] The third buckle portion is a second through hole 131, the fourth buckle portion is a second protrusion 23 for buckling with the second through hole 131, the first end of the buckle portion 113 is connected to the inner wall of the slot 112 and is close to the open end of the groove 111, the second end of the buckle portion 113 is a free end and faces the closed end of the groove 111, the buckle portion 113 extends obliquely upward from the first end to the second end to buckle in the second through hole 131 of the second buckle 13, that is, the buckle portion 113 extends obliquely upward from the bottom of the second through hole 131 into the second through hole 111. 31, the second fastener 13 is fastened and fixed to the shell body 11 through the fastening portion 113, and because the fastening portion 113 is inclined, when the second protrusion 23 enters and exits the second through hole 131, the bottom surface of the second protrusion 23 contacts the inclined upper surface of the fitting portion 113, so that the fastening portion 113 can guide the height of the second protrusion 23, so that the second protrusion 23 can enter and exit the second through hole 131 more smoothly, thereby enabling the second protrusion 23 to be more smoothly inserted into or separated from the second through hole 131.

[0041] like Figure 7As shown, the safety seat of this embodiment includes a seat body 100 and two ISOFIX connection components 200, the two ISOFIX connection components 200 are respectively arranged on both sides of the bottom of the seat body 100, and the two sides of the shell body 11 of each ISOFIX connection component 200 are respectively provided with a first connection part 115 and a second connection part 116 integrally formed, two recesses are respectively provided on both sides of the bottom of the seat body 100, and the two ISOFIX connection components 200 are respectively arranged in the two recesses, and the first connection part 115 and the second connection part 116 of each ISOFIX connection component 200 are connected to the seat body 100 by threaded fasteners, and the core rod components 20 in the two ISOFIX connection components 200 can be extended to the rear of the seat body 100, so that after the seat body 100 is placed on the car seat, the core rod components 20 in the two ISOFIX connection components 200 can be extended and connected to the ISOFIX interface on the car.
