[0046] As mentioned in the background, a child safety seat is a safety device designed specifically for children of different ages and body types. Installed in a car, it effectively improves child safety. In the event of a collision or sudden deceleration, it reduces the impact on the child and restricts their movement, minimizing harm.

[0047] The ISOFIX (International Standards Organization FIX) child safety seat anchoring system is a new standard for placing child seats in cars. Its purpose is to make the installation of child safety seats quick and simple, while providing a more rigid connection and greater safety. Therefore, child seats equipped with ISOFIX can be easily fixed to the car's fixed anchor points, increasing safety.

[0048] In the prior art, the ISOFIX mechanism is not convenient when it is retracted. For example, the ISOFIX mechanism needs to be manually adjusted to retract, which affects the user's operating experience of the child safety seat.

[0049] In view of this, please refer to Figures 1 to 11. The base and child safety seat provided in the embodiments of the present invention can solve this problem, which will be described in detail below.

[0050] The utility model provides a child safety seat, which comprises a seat and a base. The seat is mounted on a seat body 100. The child safety seat greatly improves user experience.

[0051] Specifically, please refer to Figures 1 to 3. The base is suitable for a child safety seat. The base includes a seat body 100, an ISOFIX mechanism 200 and an elastic member 300. The ISOFIX mechanism 200 includes a telescopic member 220 and a shell 210. The telescopic member 220 is slidably connected to the shell 210. The telescopic member 220 is used to lock the vehicle seat. The elastic member 300 elastically connects the telescopic member 220 and the seat body 100 at the same time. The elastic member 300 is used to drive the telescopic member 220 to retract into the shell 210.

[0052] By driving the telescopic member 220 to retract into the housing 210 through the elastic member 300, the contraction of the ISOFIX mechanism 200 is made more flexible, the convenience is improved, and the user experience is greatly enhanced.

[0053] In this embodiment, the elastic member 300 is a spring.

[0054] Among them, the telescopic part 220 includes a connecting seat 221 and a telescopic tooth 222, the connecting seat 221 and the telescopic tooth 222 are connected, the connecting seat 221 can be slidably arranged on the seat body 100, and the telescopic tooth 222 is used to connect the vehicle seat, wherein the elastic part 300 elastically connects the connecting seat 221 and the seat body 100 at the same time.

[0055] The telescopic latch 222 is slidably connected to the inner side of the housing 210, and the connecting seat 221 is slidably connected to the outer side of the housing 210. In an optional embodiment, the number of ISOFIX mechanisms 200 and elastic members 300 is two, and the two elastic members 300 are respectively connected to the telescopic members 220 of the two ISOFIX structures. The two ISOFIX structures are distributed in parallel, and the two elastic members 300 are distributed in parallel.

[0056] The base further includes two ISOFIX fixing seats 600 , which are used to fix the two shells 210 on the base body 100 respectively.

[0057] Among them, the retractable latch 222 includes a shell 2221, a latch 2222, a gear member 2223 and a connecting member 2224. The shell 2221 is slidably connected to the outer shell 210. The outer shell 210 is provided with a plurality of gear slots. The latch 2222, the gear member 2223 and the connecting member 2224 are movably arranged in the shell 2221. The latch 2222 is used to lock the vehicle seat. The latch 2222 is used to lock the outer shell 210 and the shell 2221 when it abuts the gear slot, or the latch 2222 is used to unlock the outer shell 210 and the shell 2221 when it is disengaged from the gear slot.

[0058] In addition, it should be noted that the specific structure and principle of the ISOFIX mechanism 200 can refer to ISOFIX components in the prior art and will not be described in detail here.

[0059] Among them, please refer to Figures 4 to 7. In order to facilitate the unlocking of the gear member 2223 and realize the extension of the telescopic tooth 222, the base also includes a release rope 400 and a release drive member 500. The release rope 400 is used to pull the connecting member 2224 to move, and the connecting member 2224 drives the gear member 2223 to disengage from the gear slot to unlock the shell 210 and the housing 2221. The release drive member 500 is used to pull the release rope 400 so that the release rope 400 pulls the connecting member 2224 to move.

[0060] Among them, the unlocking drive component 500 includes a unlocking push rod motor 510, a pull rope linkage 520 and a unlocking linkage 530. The unlocking push rod motor 510 is installed on the base body 100, and the pull rope linkage 520 can be movably connected to the unlocking linkage 530. The unlocking pull rope 400 is connected to the pull rope linkage 520, wherein the unlocking push rod motor 510 is used to drive the unlocking linkage 530 to move, so as to drive the pull rope linkage 520 to pull the unlocking pull rope 400.

[0061] The release push rod motor 510 pushes the release link 530 to slide relative to the base 100 , thereby driving the pull rope link 520 to slide relative to the base 100 , and the connecting member 2224 moves toward the release push rod motor 510 .

[0062] Then, the two release ropes 400 are driven to pull the connecting member 2224 through the connecting seat 221, driving the connecting member 2224 to move, and the connecting member 2224 abuts against the shift member 2223, causing the shift member 2223 to rotate, and the shift member 2223 is disengaged from the shift slot, thereby unlocking the shift member 2223 of the ISOFIX mechanism 200.

[0063] Among them, in order to facilitate the pushing out of the telescopic teeth 222, the base also includes two push rod motors 700, which are installed on the seat body 100. The push rod motor 700 is used to push the ISOFIX connecting seat 221 to extend the telescopic teeth 222 outward. At this time, the elastic member 300 will be stretched, as shown in Figures 8 and 9. When the ISOFIX mechanism 200 reaches the extended length, the push rod motor 700 retracts (as shown in Figures 10 and 11). At this time, the ISOFIX mechanism 200 is connected and fixed to the fixed anchor point of the car seat.

[0064] At the same time, the elastic member 300 is still in a stretched state, and the elastic member 300 maintains a restoring force, which helps to provide the user with a force to push the car seat back tightly, thereby improving the user's experience.

[0065] When the latch 2222 is in the unlocked state, when the ISOFIX mechanism 200 needs to be retracted to the initial position (as shown in Figure 3), the release push rod motor 510 pushes the release linkage 530 to slide relative to the seat body 100, and then the pull wire linkage can be driven to slide relative to the seat body 100, and the connecting member 2224 moves toward the direction close to the release push rod motor 510, and then drives the two release pull ropes 400 to pull the connecting member 2224 by pulling the connecting seat 221, driving the connecting member 2224 to move, and the connecting member 2224 abuts against the gear member 2223, and causes the gear member 2223 to rotate, and the gear member 2223 is disengaged from the gear slot. At this time, the gear member 2223 of the ISOFIX mechanism 200 is unlocked.

[0066] When the latching teeth 2222 are not released, when the ISOFIX mechanism needs to be retracted to the initial position after being extended, the ISOFIX mechanism 200 will directly pull it back to the initial position under the action of the return spring.

[0067] In summary, the present invention provides a base suitable for a child safety seat, the base including a seat body 100, an ISOFIX mechanism 200 and an elastic member 300, the ISOFIX mechanism 200 including a telescopic member 220 and a shell 210, the telescopic member 220 being slidably connected to the shell 210, the telescopic member 220 being used to lock the vehicle seat, the elastic member 300 elastically connecting the telescopic member 220 and the seat body 100 at the same time, the elastic member 300 being used to drive the telescopic member 220 to retract into the shell 210, and by driving the telescopic member 220 to retract into the shell 210 by the elastic member 300, the contraction of the ISOFIX mechanism 200 is improved to be more flexible, the convenience is improved, and the user experience is greatly improved.
