Therefore, it cannot be understood as a limitation on the present invention.

[0041] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0042] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0043] 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 potential harm.

[0044] 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.

[0045] In the prior art, the ISOFIX mechanism is not convenient to extend and retract. For example, the extension and retraction of the ISOFIX mechanism need to be adjusted manually, which reduces the installation efficiency of the child safety seat.

[0046] In view of this, please refer to Figures 1 to 9. 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.

[0047] The utility model provides a child safety seat, which comprises a seat and a base. The seat is mounted on a seat body 100 , and the child safety seat has all the functions of the base.

[0048] Please refer to Figures 1 and 2. Specifically, the base is suitable for a child safety seat. The base includes a seat body 100, an ISOFIX structure 200 and a telescopic drive member 300. The ISOFIX structure 200 includes a shell 210 and a telescopic member 220 slidably connected to the shell 210. The telescopic member 220 is used to lock the vehicle seat. The telescopic drive member 300 is fixedly connected to the telescopic member 220 to drive the telescopic member 220 to extend or retract into the shell 210.

[0049] The telescopic drive member 300 is used to extend the housing 210 so that the ISOFIX structure 200 reaches a certain length, and then the telescopic member 220 is connected to the fixed anchor point of the vehicle seat. Thereafter, the telescopic drive member 300 is retracted to move the child safety seat toward the vehicle seat backrest, thereby achieving pre-tightening of the child safety seat. The telescopic drive member 300 is used to drive the telescopic member 220 to extend or retract the housing 210, which facilitates the extension and retraction of the ISOFIX mechanism and improves the installation efficiency of the child safety seat.

[0050] Among them, the base also includes an ISOFIX connecting seat 221, which is slidably arranged on the base body 100. There are two ISOFIX structures 200 and two telescopic drive members 300. The two telescopic drive members 300 are respectively connected to the telescopic members 220 of the two ISOFIX structures 200. The two ISOFIX structures 200 are distributed in parallel, and the two telescopic drive members 300 are distributed in parallel. The telescopic drive member 300 is a push rod motor.

[0051] Among them, the telescopic part 220 includes a shell 2221, a latch 2222, a gear part 2223 and a connecting part 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 part 2223 and the connecting part 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.

[0052] The base further includes two ISOFIX fixing seats 600 , which are used to fix the two shells 210 on the base body 100 respectively.

[0053] In addition, it should be noted that the specific structure and principle of the ISOFIX mechanism can refer to the ISOFIX components in the prior art and will not be described in detail here.

[0054] In order to facilitate the unlocking of the gear member 2223 and 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.

[0055] 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.

[0056] Please refer to Figures 3 to 5. The release push rod motor 510 pushes the release linkage 530 to slide relative to the seat body 100, which in turn drives the pull rope linkage 520 to slide relative to the seat body 100. The connecting member 2224 moves toward the direction close to the release push rod motor 510, thereby driving the two release pull ropes 400 to pull the connecting member 2224 through the ISOFIX connecting seat 221, driving the connecting member 2224 to move. The connecting member 2224 abuts against the gear member 2223 and causes the gear member 2223 to rotate. The gear member 2223 disengages from the gear slot, thereby unlocking the gear member 2223 of the ISOFIX mechanism. At this time, as shown in Figures 6 to 8, the ISOFIX connecting seat 221 is driven to move by the telescopic driving member 300, thereby extending the telescopic tooth 222, and the tooth 2222 of the telescopic member 220 is connected to the fixed anchor point of the vehicle seat.

[0057] Finally, referring to FIG. 9 , the driving end of the telescopic driving member 300 is retracted, so that the child safety seat moves toward the vehicle seat back, thereby pushing and pre-tightening the child safety seat.

[0058] Alternatively, when the ISOFIX structure 200 needs to return to its initial state, the shift member 2223 can be unlocked first, and then the driving end of the telescopic driving member 300 is retracted to drive the telescopic teeth to retract into the housing 210, so that the ISOFIX structure 200 returns to its initial state.

[0059] In summary, the present invention provides a base suitable for a child safety seat, the base comprising a seat body 100, an ISOFIX structure 200 and a telescopic driving member 300, the ISOFIX structure 200 comprising a shell 210 and a telescopic member 220 slidably connected to the shell 210, the telescopic member 220 being used to lock the vehicle seat, the telescopic driving member 300 being fixedly connected to the telescopic member 220 to drive the telescopic member 220 to extend or retract into the shell 210, the telescopic driving member 300 is driven to extend out of the shell 210 so that the ISOFIX structure 200 reaches a certain length, and then the telescopic member 220 is connected to a fixed anchor point of the vehicle seat, thereafter, the telescopic driving member 300 is retracted so that the child safety seat moves toward the vehicle seat backrest, thereby realizing pre-tightening of the child safety seat, and the telescopic driving member 300 is used to drive the telescopic member 220 to extend or retract into the shell 210, which facilitates the extension and retraction of the ISOFIX mechanism and improves the installation efficiency of the child safety seat.

[0060] The utility model provides a child safety seat, comprising a seat and the above-mentioned base. The seat is mounted on a seat body 100. The child safety seat has all the functions of the above-mentioned base.

[0061] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
