[0060] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0061] 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.

[0062] The ISOFIX (International Standards Organization FIX) child safety seat fixing system is a new standard for placing child seats in cars. Its function is to make the installation of child safety seats quick and simple, while providing a more rigid connection and greater safety.

[0063] Therefore, a child seat equipped with ISOFIX can be easily fixed to the vehicle's fixed anchor point 10, increasing safety.

[0064] In the prior art, it is inconvenient to release the fixed anchor point 10 of the vehicle seat of the ISOFIX structure. For example, the user is required to release the lock manually, which is cumbersome and inconvenient, making it inconvenient to disassemble the child safety seat.

[0065] In view of this, please refer to Figures 1 to 24. 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. First embodiment

[0066] Please refer to FIG1 . The present invention provides a child safety seat. The child safety seat includes a seat and a base. The seat is mounted on a seat body 100 . The child safety seat is easy to disassemble.

[0067] Specifically, please refer to Figures 1 and 2. The base is used to support the seat. The base includes a seat body 100, an ISOFIX component 200, a release drive 300 and a release rope 400. The ISOFIX component 200 includes connected teeth 222 and a connector 223. The teeth 222 are used to lock the vehicle seat. The release drive 300 is installed on the seat body 100. One end of the release rope 400 is connected to the connector 223, and the other end of the release rope 400 is connected to the release drive 300.

[0068] Among them, the unlocking drive 300 is used to pull the unlocking rope 400, and the unlocking rope 400 pulls the connecting member 223 to move, so that the locking tooth 222 moves and unlocks the vehicle seat. By pulling the unlocking rope 400 by the unlocking drive 300, the locking tooth 222 releases the vehicle seat, which greatly improves the efficiency of seat disassembly, reduces the tediousness of seat disassembly, and improves the convenience of disassembling the child safety seat.

[0069] In addition, the ISOFIX assembly 200 also includes a first shell 210 and a telescopic member 220 slidably connected to the first shell 210, the telescopic member 220 includes a second shell 221, the first shell 210 is installed on the base body 100, the second shell 221 is slidably connected to the first shell 210, and the latch 222 and the connecting member 223 can be movably installed on the second shell 221.

[0070] It should be noted that, before the connecting member 223 is pulled, the connecting member 223 is used to abut against the latching teeth 222 so that the latching teeth 222 remain locked to the vehicle seat.

[0071] The base further includes two ISOFIX fixing seats 900 , which are used to fix the two first shells 210 on the base body 100 respectively.

[0072] Specifically, please refer to Figures 3 and 4, where Figure 3 is a schematic diagram of the state of the ISOFIX connecting seat 500 and the release handle 510 in Figure 1, and Figure 4 is a schematic diagram of the state of the ISOFIX component 200 in Figure 1. At this time, the tooth 222 locks the fixed anchor point on the vehicle seat.

[0073] When the child safety seat needs to be disassembled, as shown in Figures 5 to 7, the unlocking drive 300 pulls the unlocking rope 400, and the unlocking rope 400 pulls the connecting member 223 to move, so that the latch 222 releases the vehicle seat. The latch 222 releases the vehicle seat by pulling the unlocking rope 400 by the unlocking drive 300.

[0074] Please refer to Figures 1 and 2 again. In this embodiment, there are two ISOFIX components 200 and two release ropes 400. The two ISOFIX components 200 are parallel. One end of each release rope 400 is connected to the connector 223 of an ISOFIX component 200, and the other ends of the two release ropes 400 are connected to the release drive component 300.

[0075] Among them, the unlocking drive component 300 includes a unlocking push rod motor 310, two pull wire linkage components 320 and a unlocking linkage component 330. The unlocking push rod motor 310 is installed on the base body 100, and the pull wire linkage component 320 can be movably connected to the unlocking linkage component 330. The unlocking pull rope 400 is connected to the pull wire linkage component 320. Among them, the unlocking push rod motor 310 is used to drive the unlocking linkage component 330 to move, so as to drive the pull wire linkage component 320 to pull the unlocking pull rope 400.

[0076] Specifically, the base also includes an ISOFIX connector 500 and a release handle 510. The ISOFIX connector 500 is connected to the connector 223. The ISOFIX connector 500 is slidably arranged on the seat body 100. The release handle 510 is movably arranged on the ISOFIX connector 500, and the release handle 510 is simultaneously connected to the release rope 400 and the connector 223. The release drive 300 is used to pull the release rope 400 to move the release handle 510 relative to the ISOFIX connector 500, thereby driving the connector 223 to move and causing the latch 222 to release the vehicle seat.

[0077] 3 , 4 , 6 and 7 , it can be seen that the release link 330 is pushed to slide relative to the seat body 100 by the release push rod motor 310, thereby driving the pull wire link 320 to slide relative to the seat body 100, and the connector 223 moves toward the release push rod motor 310, thereby driving the two release pull ropes 400 to pull the release handle 510, so that the release handle 510 moves relative to the ISOFIX connector 500, driving the connector 223 to move, and the connector 223 and the latch 222 are connected by a tension spring. The connector 223 disengages from the latch 222, and the latch 222 rotates under the elastic force of the tension spring and releases the fixed anchor point of the vehicle seat. At this time, the child safety feature can be removed from the car seat.

[0078] In this embodiment, the base body 100 is provided with a track for facilitating the sliding of the pull-wire link 320 and the lock release link 330 , and the sliding direction of the pull-wire link 320 and the sliding direction of the lock release link 330 are at right angles.

[0079] In addition, the base further includes a release sleeve 600 , through which the release rope 400 passes. One end of the release sleeve 600 is connected to the ISOFIX connector 500 , and one end of the release sleeve 600 is connected to the base body 100 .

[0080] Please continue to refer to Figures 8 and 9. It should be noted that, in this embodiment, in order to facilitate the extension of the telescopic member 220 of the ISOFIX assembly 200, the telescopic member 220 also includes a gear member 224, which is movably mounted on the second shell 221. The gear member 224 is used to lock or unlock the first shell 210 and the second shell 221. That is, a plurality of gear slots are provided on the first shell 210, and the gear member 224 is used to press against or disengage from one of the gear slots to lock or unlock the first shell 210 and the second shell 221.

[0081] The unlocking driver 300 is used to pull the unlocking rope 400 . The unlocking rope 400 pulls the connecting member 223 to move. The connecting member 223 drives the shift member 224 to move, thereby unlocking the first housing 210 and the second housing 221 .

[0082] Specifically, the release push rod motor 310 pushes the release linkage 330 to slide relative to the base body 100, which in turn drives the pull wire linkage 320 to slide relative to the base body 100, and the connecting member 223 moves toward the direction close to the release push rod motor 310, thereby driving the two release pull ropes 400 to pull the release handle 510, so that the release handle 510 moves relative to the ISOFIX connecting seat 500, driving the connecting member 223 to move, and the connecting member 223 abuts against the gear member 224, and causes the gear member 224 to rotate, and the gear member 224 disengages from the gear slot. At this time, the first shell 210 and the second shell 221 can move relatively freely to adjust the length of the ISOFIX component 200. Second embodiment

[0083] An embodiment of the present invention further provides a child safety seat, which includes a seat and a base. The seat is mounted on a seat body 100 , and the child safety seat is easy to disassemble.

[0084] Please continue to refer to Figures 10 to 12. Unlike the base in Example 1, in this embodiment, the base also includes a return spring 700. One end of the return spring 700 is connected to the ISOFIX connecting seat 500, and the other end of the return spring 700 is connected to the base body 100. The return spring 700 is used to pull the ISOFIX connecting seat 500 to drive the second shell 221 to retract into the first shell 210, thereby making the contraction of the ISOFIX component 200 of the base more flexible and improving convenience.

[0085] At the same time, the base also includes a telescopic drive member 800, which is used to abut the ISOFIX connecting seat 500 to drive the second shell 221 to extend out of the first shell 210. The telescopic drive member 800 is a push rod motor. In this embodiment, there are two telescopic drive members 800, which are used to abut two ISOFIX connecting seats 500 respectively.

[0086] Please continue to refer to Figures 13 to 16. When the telescopic member 220 of the ISOFIX assembly 200 needs to be electrically extended, the first shell 210 and the second shell 221 are unlocked by unlocking the shift member 224 mentioned in an embodiment, that is, the release push rod motor 310 pushes the release linkage 330 to slide relative to the base 100, which can then drive the pull wire linkage 320 to slide relative to the base 100, and the connecting member 223 moves toward the direction close to the release push rod motor 310, thereby driving the two release pull ropes 400 to pull the release handle 510, so that the release handle 510 moves relative to the ISOFIX connecting seat 500, driving the connecting member 223 to move, and the connecting member 223 abuts the shift member 224, and causes the shift member 224 to rotate, and the shift member 224 disengages from the shift slot. At this time, the first shell 210 and the second shell 221 can move freely relative to each other.

[0087] Please continue to refer to Figures 17 to 20. At this time, the telescopic driving member 800 drives the ISOFIX connecting seat 500, causing the telescopic member 220 to extend outward, and the return spring 700 is stretched. As shown in Figures 21 and 22, when the ISOFIX component 200 reaches the extended length, the telescopic driving member 800 will retract. At this time, the ISOFIX component 200 is connected and fixed to the fixed anchor point of the car seat.

[0088] At the same time, the return spring maintains the return force, which helps to provide the user with a force to push the car seat back tightly, thereby improving the user's experience.

[0089] When the latch 222 is unlocked, when the ISOFIX assembly 200 needs to be retracted to the initial position, the release link 330 is pushed to slide relative to the base 100 by the release push rod motor 310, and the pull wire link 320 can be driven to slide relative to the base 100, and the connecting member 223 moves toward the release push rod motor 310, thereby driving the two release pull ropes 400 to pull the release handle 510, so that the release handle 510 moves relative to the ISOFIX connecting seat 500, driving the connecting member 223 to move, and the connecting member 223 abuts against the gear member 224 and causes the gear member 224 to rotate, and the gear member 224 disengages from the gear slot. At this time, the first shell 210 and the second shell 221 can move freely relative to each other, and ISOFIX pulls it back to the initial position under the action of the reset spring (as shown in Figures 15 and 16).

[0090] When the latch 222 is not released, when the ISOFIX needs to be retracted to the initial position after being extended, the ISOFIX component 200 can also directly pull it back to the initial position under the action of the reset spring. It should be noted that in this situation, when the second shell 221 is retracted into the first shell 210, the shift member 224 can rotate while being abutted by the first shell 210, and the shift member 224 can also be disengaged from the shift slot, so that the ISOFIX component 200 will be directly pulled back to the initial position under the action of the reset spring.

[0091] Of course, in other embodiments, the telescopic drive member 800 may be connected to the ISOFIX connecting seat 500 to drive the second shell 221 to extend or retract into the first shell 210. Furthermore, the length of the ISOFIX assembly 200 can be directly controlled by the extension and retraction of the telescopic drive member 800.

[0092] At the same time, the ISOFIX structure reaches a certain length through the telescopic drive member 800, and then the latch is connected to the fixed anchor point of the vehicle seat. Thereafter, the telescopic drive member 800 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 is used to drive the telescopic member to extend or retract the shell, which facilitates the extension and retraction of the ISOFIX component 200 and improves the installation efficiency of the child safety seat.

[0093] In addition, please refer to Figures 23 and 24. After the latch 222 of the ISOFIX component 200 is connected to the fixed anchor point of the car seat and the child safety seat is pushed tightly, a telescopic drive member 800 extends to support the ISOFIX connector 500, maintaining the position of the ISOFIX connector 500.

[0094] Of course, in other embodiments, two telescopic driving members 800 may respectively support two ISOFIX connecting seats 500.

[0095] To sum up, the base includes a seat body 100, an ISOFIX component 200, a release drive 300 and a release rope 400. The ISOFIX component 200 includes a connected latch 222 and a connector 223. The latch 222 is used to lock the vehicle seat. The release drive 300 is installed on the seat body 100. One end of the release rope 400 is connected to the connector 223, and the other end of the release rope 400 is connected to the release drive 300.

[0096] Among them, the unlocking drive 300 is used to pull the unlocking rope 400, and the unlocking rope 400 pulls the connecting member 223 to move, so that the locking tooth 222 moves and unlocks the vehicle seat. By pulling the unlocking rope 400 by the unlocking drive 300, the locking tooth 222 releases the vehicle seat, which greatly improves the efficiency of seat disassembly, reduces the tediousness of seat disassembly, and improves the convenience of disassembling the child safety seat.

[0097] The child safety seat comprises a seat and the aforementioned base, wherein the seat is mounted on the seat body 100 , and the child safety seat has all the functions of the aforementioned base.
