[0040] Optionally, in combination with Figures 1 to 7 As shown, the limiting assembly 4 includes a limiting block 41 and a first reset member 42, both ends of the first reset member 42 are connected with the base 1 and the limiting block 41 respectively, when the support leg 3 is in the folded state, the support leg 3 pushes the limiting block 41 to extend so as to realize the cooperation of the limiting block 41 and the limiting block 23; when the support leg 3 is in the open state, the limiting block 41 is retracted under the elastic force of the first reset member 42 so that the limiting block 41 and the limiting block 23 are separated from each other.

[0041] Among them, the first reset member 42 is a compression spring, when the support leg 3 is in the folded state, the support leg 3 pushes the limiting block 41 to extend, at this time the first reset member 42 is in the compressed state, when the support leg 3 is in the folded state and the ISOFIX 21 is in the storage state, the limiting block 41 can limit the ISOFIX 21 to extend; when the support leg 3 is opened, the limiting block 41 loses the pushing force of the support leg 3, and the limiting block 41 moves and retracts under the spring force of the first reset member 42, at this time the limiting block 41 and the limiting block 23 are completely separated, the ISOFIX 21 can freely move forward and backward in the sleeve 22, when the ISOFIX 21 is adjusted to the appropriate extension length, the position between the ISOFIX 21 and the sleeve 22 is fixed, the child safety seat is installed on the car seat, and the structure is simple and reliable.

[0042] Optionally, in combination with Figures 1 to 7As shown, the limiting assembly 4 further comprises a limiting push block 43 and a second reset member 44, the limiting push block 43 is movably connected with the limiting block 41, and the two ends of the second reset member 44 are connected with the limiting push block 43 and the limiting block 41 respectively; when the support leg 3 is in the folded state, the limiting push block 43 abuts against the support leg 3.

[0043] In this embodiment, the second reset member 44 is a compression spring, when the support leg 3 is in the folded state, the support leg 3 contacts the limiting push block 43 and pushes the limiting push block 43 to move outward, the limiting push block 43 compresses the second reset member 44, and the limiting block 41 moves outward under the spring pushing force of the second reset member 44, at this time the first reset member 42 is in the compressed state, when the support leg 3 is in the folded state and the ISOFIX 21 is in the storage state, the limiting block 41 can limit the ISOFIX 21 to extend out; when the support leg 3 is opened, the limiting push block 43 loses the pushing force of the support leg 3, the limiting block 41 moves to retract under the spring force of the first reset member 42, the limiting block 41 compresses the second reset member 44, and the limiting push block 43 moves inward under the spring pushing force of the second reset member 44, at this time the limiting block 41 is completely separated from the limiting block 23, and the ISOFIX 21 can move freely in the sleeve 22, when the ISOFIX 21 is adjusted to the appropriate extension length, the locking gear is locked to fix the positions of the ISOFIX 21 and the sleeve 22 relative to each other, and the installation of the child safety seat on the car seat is completed.

[0044] In this embodiment, the limiting push block 43 and the limiting block 41 are movably connected, when the support leg 3 is in the folded state, the force acting on the limiting block 41 can change the position between the limiting block 41 and the limiting push block 43, so as to move the extension length of the ISOFIX 21 in special cases. When the support leg 3 is in the folded state and the ISOFIX 21 is also in the storage state, this state is a common initial state when the child seat is shipped, and is also the state after the child safety seat is disassembled from the car after use.

[0045] In this embodiment, the ISOFIX 21 cannot normally slide and extend out because the limiting block 23 is blocked by the limiting block 41, the support leg 3 needs to be rotated and pulled out to open, the limiting push block 43 slides inward under the action of the second reset member 44, and the limiting push block 43 also slides inward under the action of the first reset member 42, at this time the limiting block 23 is not blocked by the limiting block 41, the ISOFIX 21 can extend out and retract, and the installation of the seat is completed, which avoids the risk of forgetting to use the support leg 3 by the consumer during use, and improves the safety of children traveling.

[0046] Optionally, in combination with Figure 8 , Figure 9As shown, the limiting push block 43 is provided with a first guide surface 431, and the support leg 3 is provided with a second guide surface 31 adapted to cooperate with the first guide surface 431.

[0047] When the consumer uses the full child safety seat and needs to disassemble the child safety seat from the car for storage, that is, when the support leg 3 needs to be switched from the open state to the folded state, the opening sequence can be reversed and operated again, that is, the ISOFIX 21 is first retracted to the initial position, and then the support leg 3 is rotated and folded to be retracted to the fully stored state. At this time, the limiting push block 43 is extruded and moved outward under the contact force of the first guide surface 431 and the second guide surface 31, and the limiting block 41 is driven outward by the limiting push block 43 to block the limiting block 23.

[0048] Optionally, in combination with Figure 10 、 Figure 11 As shown, the limiting block 41 is provided with a third guide surface 411, and the limiting block 23 is provided with a fourth guide surface 232 adapted to cooperate with the third guide surface 411.

[0049] When the ISOFIX 21 is in the extended state, the consumer can arbitrarily fold and store the support leg 3. At this time, the limiting push block 43 is extruded outward by the cooperation of the first guide surface 431 and the second guide surface 31, and the limiting block 41 is driven outward by the limiting push block 43. The ISOFIX 21 is still in the extended state and can be freely retracted to the initial position without being limited by the outwardly extended limiting block 41; when the ISOFIX 21 is retracted to the position where the limiting block 23 contacts the limiting block 41, the limiting block 23 and the limiting block 41 cooperate with the third guide surface 411 and the fourth guide surface 232. The limiting block 41 moves inward in the sliding groove 433 of the limiting push block 43, and the second reset member 44 between the limiting block 41 and the limiting push block 43 is compressed until the limiting block 23 slides past the limiting block 41 to the initial position. At this time, the limiting block 41 moves outward under the action of the first reset member 42 to block the limiting block 23.

[0050] Optionally, in combination with Figure 4 、 Figure 5 As shown, the base 1 is provided with a through slot 11 for mounting the limiting push block 43, and the limiting push block 43 is slidably connected with the through slot 11. The limiting push block 43 can move freely in the left and right directions in the through slot 11, which can ensure the stability of the movement of the limiting push block 43 and realize the position transformation of the limiting push block 43.

[0051] Optionally, in combination with Figure 2 、 Figure 5As shown, the limiting block 41 is provided with a sliding block 412, and the limiting push block 43 is provided with a sliding groove 433 in sliding connection with the sliding block 412. The second reset member 44 is installed in the sliding groove 433, and the sliding block 412 is arranged in the sliding groove 433, so that the sliding groove 433 and the sliding block 412 are in sliding connection with each other, so that the length of the limiting block 41 and the limiting push block 43 as a whole can be changed, so that the limiting assembly 4 can adapt to various use states.

[0052] Optionally, in combination with Figure 2 、 Figure 5 As shown, the sliding groove 433 is provided with a first through hole 432, the sliding block 412 is provided with a second through hole 413, the base 1 is provided with a limiting column 12 penetrating the first through hole 432 and the second through hole 413 in sequence, and the first through hole 432 and the second through hole 413 are in sliding connection with the limiting column 12. The first through hole 432 and the second through hole 413 are both long strip-shaped holes, the limiting column 12 can freely move left and right in the first through hole 432 and the second through hole 413, which can ensure the mutual movement between the limiting block 41 and the limiting push block 43, and can also prevent the limiting block 41 and the limiting push block 43 from being separated from each other, ensuring the stability of the structure, and the overall structure is more compact.

[0053] Another embodiment of the present application provides a support leg anti-forgetting method, in combination with Figures 1 to 11 As shown, based on the support leg anti-forgetting structure as described above, the support leg anti-forgetting method comprises the following steps:

[0054] When the ISOFIX 21 is switched to the storage state and the support leg 3 is switched to the folded state, the limiting assembly 4 cooperates with the limiting block 23 to limit the ISOFIX 21 from extending;

[0055] When the support leg 3 is switched to the open state, the limiting assembly 4 and the limiting block 23 are separated from each other, and the ISOFIX 21 can extend relative to the sleeve 22.

[0056] The child safety seat in the embodiment, when the ISOFIX 21 is in the storage state and the support leg 3 is in the folded state, the base 1 is movably connected with the limiting assembly 4 capable of limiting the movement of the ISOFIX 21, so that only when the support leg 3 is first opened and the support leg 3 is in the open state, the ISOFIX 21 can extend from the sleeve 22 for subsequent fixation with the car seat, which can effectively prevent the user from forgetting to open the support leg 3 when using the child safety seat, and ensure the safety of the child.

[0057] Optionally, the limiting assembly 4 comprises a limiting block 41 and a first reset member 42;

[0058] Switching the support leg 3 to the folded state, the support leg 3 pushes the limiting block 41 to extend, and the limiting block 41 cooperates with the limiting block 23 when the ISOFIX 21 is in the storage state.

[0059] Switching the support leg 3 to the unfolded state, the limiting block 41 is retracted under the elastic force of the first reset member 42, and the limiting block 41 and the limiting block 23 are separated from each other.

[0060] Among them, the first reset member 42 is a compression spring, when the support leg 3 is in the folded state, the support leg 3 pushes the limiting block 41 to extend, at this time the first reset member 42 is in the compressed state, when the support leg 3 is in the folded state and the ISOFIX 21 is in the storage state, the limiting block 41 can limit the ISOFIX 21 to extend; when the support leg 3 is unfolded, the limiting block 41 loses the pushing force of the support leg 3, and the limiting block 41 moves and retracts under the spring force of the first reset member 42, at this time the limiting block 41 and the limiting block 23 are completely separated, the ISOFIX 21 can freely move forward and backward in the sleeve 22, when the ISOFIX 21 is adjusted to the appropriate extension length, the lock gear is fixed to fix the position between the ISOFIX 21 and the sleeve 22, the child safety seat is installed on the car seat, the structure is simple and reliable.

[0061] Optionally, the limiting assembly 4 further comprises a limiting push block 43 and a second reset member 44, two ends of the second reset member 44 are connected with the limiting push block 43 and the limiting block 41 respectively.

[0062] Switching the support leg 3 to the folded state, the support leg 3 abuts against the limiting push block 43 and pushes the limiting block 41 to extend, and the limiting block 41 cooperates with the limiting block 23 when the ISOFIX 21 is in the storage state.

[0063] Switching the support leg 3 to the unfolded state, the limiting block 41 is retracted under the elastic force of the first reset member 42, and the limiting block 41 and the limiting block 23 are separated from each other, and the limiting push block 43 moves inward and resets under the elastic force of the second reset member 44.

[0064] The second reset member 44 is a compression spring. When the support leg 3 is in the folded state, the support leg 3 contacts the limiting push block 43 and pushes the limiting push block 43 to move outward, the limiting push block 43 compresses the second reset member 44, and the limiting block 41 moves outward under the spring pushing force of the second reset member 44. At this time, the first reset member 42 is in a compressed state. When the support leg 3 is in the folded state and the ISOFIX 21 is in the storage state, the limiting block 41 can limit the ISOFIX 21 from extending. When the support leg 3 is opened, the limiting push block 43 loses the pushing force of the support leg 3, the limiting block 41 moves and retracts under the spring force of the first reset member 42, the limiting push block 43 moves inward under the spring pushing force of the second reset member 44, and at this time, the limiting block 41 is completely separated from the limiting block 23. The ISOFIX 21 can move freely in the sleeve 22. When the ISOFIX 21 is adjusted to the appropriate extension length, the lock position is fixed to the position between the ISOFIX 21 and the sleeve 22, and the child safety seat is installed on the car seat.

[0065] In the embodiment, the limiting push block 43 and the limiting block 41 are movably connected. When the support leg 3 is in the folded state, the force acting on the limiting block 41 can change the position between the limiting block 41 and the limiting push block 43, so as to move the extension length of the ISOFIX 21 in special cases. When the support leg 3 is in the folded state and the ISOFIX 21 is also in the storage state, this state is a common initial state when the child seat is shipped from the factory, and is also the state after the child safety seat is removed from the car after use.

[0066] In the embodiment, the ISOFIX 21 cannot normally slide and extend because the limiting block 23 is blocked by the limiting block 41. The support leg 3 needs to be rotated and pulled out to open. The limiting push block 43 slides inward under the action of the second reset member 44, and the limiting push block 43 also slides inward under the action of the first reset member 42. At this time, the limiting block 23 is not blocked by the limiting block 41, the ISOFIX 21 can extend and retract, and the seat installation is completed. This avoids the risk of forgetting to use the support leg 3 by the consumer during use, and improves the safety of children traveling

[0067] Optionally, the limiting block 41 is provided with a third guide surface 411, and the limiting block 23 is provided with a fourth guide surface 232 adapted to cooperate with the third guide surface 411.

[0068] During switching the support leg 3 to the folded state and switching the ISOFIX 21 from the extended state to the storage state, the third guide surface 411 is in abutting cooperation with the fourth guide surface 232, the limiting block 23 pushes the limiting stopper 41 to move inward until the limiting block 23 slides through the limiting stopper 41 to the initial position, and the limiting stopper 41 moves outward under the elastic force of the first reset member 42 to limit the movement of the limiting block 23.

[0069] When the ISOFIX 21 is in the extended state, the consumer can fold and store the support leg 3 at will, at this time, the limiting push block 43 is extruded outward by the cooperation of the first guide surface 431 and the second guide surface 31, the limiting stopper 41 is driven outward by the limiting push block 43, the ISOFIX 21 is still in the extended state, and the ISOFIX 21 can be freely retracted to the initial position without being limited by the outwardly extended limiting stopper 41; when the ISOFIX 21 is retracted to the position where the limiting block 23 contacts the limiting stopper 41, the limiting block 23 and the limiting stopper 41 are cooperated by the third guide surface 411 and the fourth guide surface 232, the limiting stopper 41 moves inward in the sliding groove 433 of the limiting push block 43, the second reset member 44 between the limiting stopper 41 and the limiting push block 43 is compressed, and the limiting block 23 slides through the limiting stopper 41 to the initial position, at this time, the limiting stopper 41 moves outward under the action of the first reset member 42 to block the limiting block 23.

[0070] Another embodiment of the present application provides a child safety seat, characterized in that the support leg forgetting prevention structure is as described above.
