Therefore, child seats equipped with ISOFIX can be easily fixed to the car's anchor points for added safety.

In the existing technology, the convenience of retracting the ISOFIX mechanism is poor. For example, it is necessary to manually adjust the retraction of the ISOFIX mechanism, which affects the user's operating experience of the child safety seat.

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

The utility model provides a child safety seat. The child safety seat includes a seat and a base. The seat is installed on a base body 100. The child safety seat greatly improves user experience.

Specifically, please refer to Figures 1 to 3. The base is suitable for child safety seats. The base includes a base 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 can Slidingly connected to the shell 210, the telescopic member 220 is used to lock the vehicle seat. The elastic member 300 is elastically connected to the telescopic member 220 and the seat 100 at the same time. The elastic member 300 is used to drive the telescopic member 220 to retract the shell 210.

The elastic member 300 drives the telescopic member 220 to retract the housing 210, which makes the contraction of the ISOFIX mechanism 200 more flexible, improves convenience, and greatly improves user experience.

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

The telescopic member 220 includes a connecting base 221 and telescopic teeth 222. The connecting base 221 is connected to the telescopic teeth 222. The connecting base 221 is slidably provided on the base body 100. The telescopic teeth 222 are used to connect to vehicle seats, where, The elastic member 300 elastically connects the connection base 221 and the base body 100 at the same time.

The telescopic teeth 222 are slidably connected to the inside of the housing 210, and the connecting seat 221 is slidably connected to the outside of the housing 210. There are two ISOFIX mechanisms 200 and two elastic members 300, and the two elastic members 300 are respectively connected to two ISOFIX mechanisms. Of the telescopic member 220, the two ISOFIX mechanisms are distributed in parallel, and the two elastic members 300 are distributed in parallel.

The base also includes two ISOFIX fixing seats 600. The two ISOFIX fixing seats 600 are respectively used to fix the two shells 210 on the base body 100.

Among them, the telescopic latch 222 includes a housing 2221, a latch 2222, a gear piece 2223 and a connecting piece 2224. The housing 2221 is slidably connected to the shell 210. The shell 210 is provided with a plurality of gear slots. The latch 2222 The gear piece 2223 and the connecting piece 2224 are movably arranged in the housing 2221. The latch teeth 2222 are used to lock the vehicle seat. The latch teeth 2222 are used to lock the housing 210 and the gear position slot when abutting against the gear slot. The housing 2221 or the latching teeth 2222 are used to unlock the housing 210 and the housing 2221 when disengaged from the gear slot.

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

Please refer to Figures 4 to 7. In order to facilitate unlocking of the gear member 2223 and extending the telescopic teeth 222, the base also includes a release pull cord 400 and a release driver 500. The release pull cord 400 is used for Pull the connecting piece 2224 to move, and the connecting piece 2224 drives the gear piece 2223 to disengage from the gear slot to unlock the housing 210 and the housing 2221. The lock release driver 500 is used to pull the lock release pull cord 400, so that the lock release pull cord 400 Pull connector 2224 to move.

Among them, the release driving member 500 includes a release push rod motor 510, a pull cord linkage 520 and a release linkage 530. The release push rod motor 510 is installed on the base 100, and the pull cord linkage 520 is movable. Connected to the release linkage 530, the release pull cord 400 is connected to the pull cord linkage 520, wherein the release push rod motor 510 is used to drive the release linkage 530 to move to drive the pull cord linkage 520 Pull the lock release cord 400.

The release push rod motor 510 pushes the release linkage 530 to slide relative to the base 100 , thereby driving the rope linkage 520 to slide relative to the base 100 , and the connecting member 2224 moves in a direction close to the release pushrod motor 510 move.

Then the two release pull ropes 400 are driven to pull the connecting piece 2224 through the connecting seat 221, driving the connecting piece 2224 to move, the connecting piece 2224 contacts the gear piece 2223, and causes the gear piece 2223 to rotate, and the gear piece 2223 is separated from the gear card. slot to realize the unlocking of the gear piece 2223 of the ISOFIX mechanism 200.

Among them, in order to facilitate the push-out of the telescopic teeth 222, the base also includes two push rod motors 700. The push rod motors 700 are installed on the base 100. The push rod motors 700 are used to push the ISOFIX connection base 221 to make 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 with the fixed anchor point of the car seat.

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 provide the user with a force to push the car seat back tightly, thereby improving the user's use experience.

When the latch teeth 2222 are released, when the telescopic member 220 of the ISOFIX mechanism 200 needs to be retracted to the initial position (as shown in FIG. 3 ), the release push rod motor 510 pushes the release linkage 530 relative to the base. 100 slides, thereby driving the cable linkage to slide relative to the base 100, and the connecting piece 2224 moves in a direction close to the release push rod motor 510, thereby driving the two lock releasing pull cords 400 to pull the connecting piece 2224 by pulling the connecting seat 221. , driving the connecting piece 2224 to move, the connecting piece 2224 contacts the gear piece 2223, and rotates the gear piece 2223, and the gear piece 2223 is separated from the gear slot. At this time, the gear piece 2223 of the ISOFIX mechanism 200 is unlocked, and ISOFIX is realized. The telescopic member 220 of the mechanism 200 pulls it back to the initial position under the force of the elastic member 300 .

When the latch teeth 2222 are not released, when the telescopic part 220 of the ISOFIX mechanism needs to be retracted to the initial position after being extended, the telescopic part 220 of the ISOFIX mechanism 200 can also be directly pulled back under the force of the elastic member 300 to the initial position. It should be noted that in this situation, when the housing 2221 retracts into the housing 210, the gear member 2223 can rotate while being contacted by the housing 210, and the gear member 2223 can also rotate. After being disengaged from the gear slot, the telescopic component 220 of the ISOFIX mechanism 200 will directly pull it back to the initial position under the force of the elastic component 300 .

To sum up, the present utility model provides a base suitable for child safety seats. The base includes a base 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 slidable. Groundly connected to the shell 210, the telescopic member 220 is used to lock the vehicle seat, the elastic member 300 is elastically connected to the telescopic member 220 and the seat 100 at the same time, the elastic member 300 is used to drive the telescopic member 220 to retract the shell 210, and the elastic member 300 is used to drive the telescopic member 220 to retract the shell 210.
