[0057] A child safety seat can be installed in a vehicle to provide reliable safety protection for infants and young children. The vehicle can be a car, a train, a ship, an airplane, or other vehicles.

[0058] The front direction of the base 11 is consistent with the front direction of the vehicle, and the left-right direction of the base 11 is consistent with the left-right direction of the vehicle.

[0059] Figure 1 is a structural schematic view of some embodiments of the child safety seat provided by the utility model.

[0060] The child safety seat comprises a base assembly 1 and a basket 2. The base assembly 1 comprises a base 11 and a turntable 12, and the turntable 12 can rotate relative to the base 11. The basket 2 is detachably arranged on the turntable 12. The basket 2 is used to carry infants. Since the base 11 is fixed after being installed on the vehicle, the front-rear direction of the base 11 is consistent with the front-rear direction of the vehicle, and the left-right direction of the base 11 is consistent with the left-right direction of the vehicle. Since the turntable 12 can rotate relative to the base 11, the turntable 12 can be rotated as required, so that the basket 2 faces the rear side of the vehicle (the rear side of the base 11), or the basket 2 faces the front side of the vehicle (the front side of the base 11).

[0061] The child safety seat further comprises a clamping assembly 3 arranged on the turntable 12. When the basket 2 is installed on the turntable 12, the basket 2 can be locked by the clamping assembly 3, thereby improving the stability of the basket 2 on the turntable 12. When the basket 2 needs to be detached, the basket 2 can be unlocked by the clamping assembly 3.

[0062] In order to improve the safety of infants on the child safety seat, it is necessary to ensure that the basket 2 faces the rear side of the base 11, or that the basket 2 faces the front side of the base 11, and that the clamping assembly 3 has locked the basket 2. When both conditions are met, the child safety seat is considered to be in a correct use state.

[0063] The rear side of the base 11, or the front side of the base 11 can be set as the correct position of the turntable 12 relative to the base 11. The “preset position” in the following of the utility model is the correct position, including the above two cases. Therefore, when the position of the turntable 12 relative to the base 11 is the preset position, the front-rear direction of the turntable 12 is consistent with the front-rear direction of the base 11, or the front-rear direction of the turntable 12 is opposite to the front-rear direction of the base 11.

[0064] Since in actual operation, the user cannot determine whether the child safety seat is in the correct use state by observation, or due to improper operation, there is also a case that the child safety seat is not in the correct use state and is not found, causing the child safety seat to have a safety hazard. Among them, the safety hazard includes: when the vehicle suddenly brakes or collides, the basket 2 falls off, the infant passenger and the basket are thrown out together, and the child safety seat does not play a safety protection role.

[0065] Based on this, the utility model embodiment provides a child safety seat which can be used to find the safety hazard of the child safety seat in time.

[0066] Reference Figure 2 And Figure 3 In some embodiments, the child safety seat comprises a base assembly 1, the base assembly 1 comprises a base 11 and a rotating disc 12, the rotating disc 12 is rotatably arranged on the base 11, and the rotating disc 12 is provided with a window 13. Optionally, the rotating disc 12 is provided with the window 13 on the left side or one side thereof.

[0067] The child safety seat further comprises a clamping assembly 3, the clamping assembly 3 is arranged on the rotating disc 12, and the clamping assembly 3 comprises a first working condition and a second working condition for respectively corresponding locking and unlocking with the basket 2. That is, the clamping assembly 3 is locked with the basket 2, which is the first working condition of the clamping assembly 3; the clamping assembly 3 is unlocked with the basket 2, which is the second working condition of the clamping assembly 3.

[0068] Reference Figures 2 to 4 The child safety seat further comprises a linkage assembly 4, the linkage assembly 4 comprises a first mark 411 and a second mark 412. The linkage assembly 4 is responsive to the relative position of the rotating disc 12 and the base 11 being a preset position and the clamping assembly 3 being in the first working condition, so that the first mark 411 is located in the window 13; the linkage assembly 4 is also responsive to at least one of the relative position of the rotating disc 12 and the base 11 being a non-preset position and the clamping assembly 3 being a non-first working condition, so that the second mark 412 is located in the window 13.

[0069] Reference Figure 2 The relative position of the rotating disc 12 and the base 11 is a preset position, and in the case that the clamping assembly 3 is in the first working condition, that is, the clamping assembly 3 is locked with the basket 2, the window 13 displays the first mark 411.

[0070] Reference Figure 3 The rotating disc 12 is rotated by 90 degrees relative to the base 11, the relative position of the rotating disc 12 and the base 11 is a non-preset position, and at this time, no matter whether the clamping assembly 3 is in the first working condition or in the second working condition, the window 13 displays the second mark 412. Among them, the rotating disc 12 can be rotated by 90 degrees clockwise or counterclockwise relative to the base 11.

[0071] And, in the case that the relative position of the turntable 12 and the base 11 is the preset position, and the engaging assembly 3 is in the second working condition, the window 13 also displays the second mark 412.

[0072] That is to say, only in the case that the relative position of the turntable 12 and the base 11 is the preset position, and the engaging assembly 3 is in the first working condition, both conditions are met at the same time, it is considered that the child safety seat is in the correct use state, and the window 13 displays the first mark 411. In other cases that do not meet the correct use state, the window 13 displays the second mark 412.

[0073] The first mark 411 and the second mark 412 can be different colors, for example, the first mark 411 is green, and the second mark 412 is red. Alternatively, the first mark 411 and the second mark 412 can be different words, letters, symbols or numbers, etc., for example, the first mark 411 is the letter T, and the second mark 412 is the letter F, etc.

[0074] Therefore, the user can judge whether the child safety seat is in the correct use state according to the mark displayed by the window 13, and in the case that the child safety seat is in the incorrect use state, timely inspection and adjustment can be performed to avoid safety hazards.

[0075] Reference Figure 4 In some embodiments, the linkage assembly 4 includes a mark piece 41 and a guide piece 42.

[0076] The mark piece 41 is movably arranged on the turntable 12, and the mark piece 41 is configured to rotate with the turntable 12. The first mark 411 and the second mark 412 are arranged on the mark piece 41.

[0077] The guide piece 42 is arranged on the base 11, and the guide piece 42 is configured to guide and limit the mark piece 41.

[0078] In the above embodiments, the mark piece 41 is movably arranged on the turntable 12, and the mark piece 41 can translate relative to the turntable 12. Since the mark piece 41 is arranged on the turntable 12, the mark piece 41 can also rotate with the turntable 12 during the rotation of the turntable 12 relative to the base 11. Whether the mark piece 41 translates relative to the turntable 12 or the mark piece 41 rotates with the turntable 12, the guide piece 42 guides and limits the mark piece 41, so as to facilitate the first mark 411 or the second mark 412 to be located in the window 13.

[0079] Reference Figure 5 And Figure 6In some embodiments, the guide member 42 includes a strip groove 421, the length of which extends in the same direction as the front-rear direction of the base 11. The marker member 41 is provided with a slider 413 that inserts into the strip groove 421. The slider 413 moves along the strip groove 421, enabling the marker member 41 to translate relative to the turntable 12.

[0080] In the above embodiment, the guide member 42 includes a strip groove 421, and the marker member 41 is provided with a slider 413 inserted into the strip groove 421. The marker member 41 rotates with the turntable 12, and the marker member 41 translates relative to the turntable 12. The strip groove 421 can guide and restrict the slider 413 to enable the first marker 411 or the second marker 412 to be operably positioned in the window 13.

[0081] In some embodiments, the projection of the center of rotation of the turntable 12 relative to the base 11 onto the base 11 falls into the strip groove 421.

[0082] During the rotation of the turntable 12 relative to the base 11, the marker 41 rotates with the turntable 12 relative to the base 11. When the slider 413 is not located at the center of the turntable 12, as the turntable 12 rotates, the slider 413 can be pushed towards the center of the turntable 12 through the strip groove 421. Therefore, during the rotation of the turntable 12 relative to the base 11, the strip groove 421 can push the slider 413 to move, thereby realizing the translation of the marker 41 relative to the turntable 12, which is then used to position the first marker 411 or the second marker 412 in the window 13.

[0083] In some embodiments, the strip groove 421 is located in the middle of the left and right sides of the base 11. The projection of the center of the turntable 12 onto the base 11 falls into the strip groove 421.

[0084] In the above embodiment, the length extension direction of the strip groove 421 is consistent with the front-rear direction of the base 11. The strip groove 421 restricts the slider 413, so that the slider 413 can only move along the length extension direction of the strip groove 421, that is, the slider 413 can only move in the front-rear direction of the base 11, and cannot move in the left-right direction of the base 11. Optionally, the dimension of the strip groove 421 in the left-right direction is slightly larger than the dimension of the slider 413 in the left-right direction.

[0085] refer to Figure 4 In some embodiments, the linkage component 4 further includes a first connector 43 and a second connector 44.

[0086] The first connector 43 connects the identification piece 41 and the locking assembly 3.

[0087] The second connector 44 connects the identifier 41 and the turntable 12.

[0088] In the state that the relative position of the turntable 12 and the base 11 is the preset position, one of the first connecting member 43 and the second connecting member 44 extends to the rear side of the base 11, and the other extends to the front side of the base 11.

[0089] In the above embodiment, in the state that the relative position of the turntable 12 and the base 11 is the preset position, one of the first connecting member 43 and the second connecting member 44 extends to the rear side of the base 11, and the other extends to the front side of the base 11, the first connecting member 43 and the second connecting member 44 are opposite in the direction of the acting force on the identification member 41, so that the identification member 41 can be moved to the direction of approaching or moving away from the clamping assembly 3 through the cooperation of the first connecting member 43 and the second connecting member 44, so as to realize the positioning of the first identification 411 or the second identification 412 in the window 13.

[0090] In Figure 4 In the embodiment shown, the first connecting member 43 is connected to the identification member 41 and extends to the rear side of the base 11, and the second connecting member 44 is connected to the identification member 41 and extends to the front side of the base 11.

[0091] In some embodiments, the second connecting member 44 is configured to provide the identification member 41 with an acting force to move the identification member 41 away from the clamping assembly 3; in the case that the clamping assembly 3 is in the second working condition, the clamping assembly 3 provides the identification member 41 with an acting force to move the identification member 41 to approach the clamping assembly 3 through the first connecting member 43, and the acting force of the first connecting member 43 is greater than that of the second connecting member 44; in the case that the clamping assembly 3 is in the first working condition, the clamping assembly 3 removes the acting force provided by the first connecting member 43 to the identification member 41 to move the identification member 41 to approach the clamping assembly 3.

[0092] In the above embodiment, in the state that the relative position of the turntable 12 and the base 11 is the preset position, the clamping assembly 3 removes the acting force provided by the first connecting member 43 to the identification member 41 to move the identification member 41 to approach the clamping assembly 3 in the case that the clamping assembly 3 is in the first working condition, and the second connecting member 44 is configured to provide the identification member 41 with an acting force to move the identification member 41 away from the clamping assembly 3, and the second connecting member 44 pulls the identification member 41 to move in the direction of moving away from the clamping assembly 3 relative to the turntable 12, so as to enable the first identification 411 to be positioned in the window 13.

[0093] In the case that the relative position of the turntable 12 and the base 11 is the preset position, and the clamping assembly 3 is in the first working condition, the first connecting piece 43 provides an acting force to the marker 41 to make the marker 41 close to the clamping assembly 3, and the acting force of the first connecting piece 43 is greater than that of the second connecting piece 44; the first connecting piece 43 overcomes the acting force of the second connecting piece 44, pulls the marker 41 to move relative to the turntable 12, and moves in the direction close to the clamping assembly 3, so that the second marker 412 is located in the window 13.

[0094] Reference Figure 4 In some embodiments, in the case that the relative position of the turntable 12 and the base 11 is the preset position, and the clamping assembly 3 is in the first working condition, the sliding block 413 is located at the end of the strip-shaped groove 421 away from the clamping assembly 3, and the sliding block 413 deviates from the center of the turntable 12.

[0095] In the above embodiments, in the case that the relative position of the turntable 12 and the base 11 is the preset position, the front-rear direction of the turntable 12 is the same as or opposite to the front-rear direction of the base 11. Figure 4 In the embodiment shown in the figure, the front-rear direction of the turntable 12 corresponding to the preset position is opposite to the front-rear direction of the base 11, and the basket 2 faces the rear side of the base 11.

[0096] In the case that the relative position of the turntable 12 and the base 11 is the preset position, and the clamping assembly 3 is in the first working condition, which is the correct use state of the child safety seat, the first marker 411 is located in the window 13, at this time, the sliding block 413 is located at the end of the strip-shaped groove 421 away from the clamping assembly 3, and the sliding block 413 deviates from the center of the turntable 12. Since the sliding block 413 deviates from the center of the turntable 12, in the process of rotating the turntable 12, the strip-shaped groove 421 will push the sliding block 413 to move towards the center of the turntable 12, so that in the process of converting the relative position of the turntable 12 and the base 11 to the non-preset position, the first marker 411 switches to the second marker 412; after the turntable 12 rotates 90 degrees relative to the base 11 from the preset position, one of the first connecting piece 43 and the second connecting piece 44 extends to the left side of the base 11, and the other extends to the right side of the base 11. Since the strip-shaped groove 421 restricts the movement of the sliding block 413 along the left-right direction of the base 11, the second connecting piece 44 cannot pull the marker 41 away from the clamping assembly 3, so that in the case that the relative position of the turntable 12 and the base 11 is the non-preset position, and the clamping assembly 3 is in the first working condition, the second marker 412 remains in the window 13.

[0097] In some embodiments, in the case that the relative position of the turntable 12 and the base 11 is the preset position, and the clamping assembly 3 is in the second working condition, the sliding block 413 is located at the end of the strip-shaped groove 421 close to the clamping assembly 3, and the sliding block 413 is located at the center of the turntable 12.

[0098] In the above embodiment, when the relative position of the rotating disc 12 and the base 11 is the preset position, and the clamping assembly 3 is in the first working condition, the first connecting member 43 removes the force provided by the identification member 41 to make the identification member 41 close to the clamping assembly 3, the second connecting member 44 is configured to provide a force to the identification member 41 to make the identification member 41 away from the clamping assembly 3, the second connecting member 44 pulls the identification member 41 to move away from the clamping assembly 3, so that the first identification 411 is located in the window 13, at this time, the sliding block 413 is located at the end of the strip-shaped slot 421 away from the clamping assembly 3, and the sliding block 413 deviates from the center of the rotating disc 12. When the clamping assembly 3 is in the second working condition, the first connecting member 43 provides a force to the identification member 41 to make the identification member 41 close to the clamping assembly 3, and the force of the first connecting member 43 is greater than the force of the second connecting member 44, the first connecting member 43 overcomes the force of the second connecting member 44, and pulls the identification member 41 to move close to the clamping assembly 3, so that the second identification 412 is located in the window 13, at this time, the sliding block 413 is located at the end of the strip-shaped slot 421 close to the clamping assembly 3, and the sliding block 413 is located at the center of the rotating disc 12.

[0099] In some embodiments, when the rotating disc 12 rotates 90 degrees relative to the base 11 from the preset position, and the clamping assembly 3 is in the first working condition, the sliding block 413 is located at the center of the rotating disc 12. Alternatively, the sliding block 413 is located at the end of the strip-shaped slot 421 close to the rear side of the base 11.

[0100] In some embodiments, when the rotating disc 12 rotates 90 degrees relative to the base 11 from the preset position, and the clamping assembly 3 is in the second working condition, the sliding block 413 is located at the center of the rotating disc 12. Alternatively, the sliding block 413 is located at the end of the strip-shaped slot 421 close to the rear side of the base 11.

[0101] In the above embodiment, when the relative position of the rotating disc 12 and the base 11 is the preset position, and the clamping assembly 3 is in the first working condition, which is the correct use state of the child safety seat, the first identification 411 is located in the window 13, at this time, the sliding block 413 is located at the end of the strip-shaped slot 421 away from the rear side of the base 11, and the sliding block 413 deviates from the center of the rotating disc 12. Since the sliding block 413 deviates from the center of the rotating disc 12, in the process of rotating the rotating disc 12, the strip-shaped slot 421 will push the sliding block 413 to move to the center of the rotating disc 12, so that in the process of converting the relative position of the rotating disc 12 and the base 11 to the non-preset position, the first identification 411 switches to the second identification 412; after the rotating disc 12 rotates 90 degrees relative to the base 11 from the preset position, the second identification 412 is located in the window 13, and the sliding block 413 is located at the center of the rotating disc 12, and the sliding block 413 is located at the end of the strip-shaped slot 421 close to the rear side of the base 11.

[0102] ReferenceFigure 7 When the rotary disc 12 rotates 90 degrees from the preset position relative to the base 11, the slider 413 is located at the center of the rotary disc 12, and the second mark 412 is located in the window 13, no matter the clamping assembly 3 is in the first working condition or the second working condition. Optionally, the slider 413 is located at the end of the strip-shaped slot 421 close to the rear side of the base 11.

[0103] In some embodiments, during the rotation of the rotary disc 12 from the preset position relative to the base 11, the slider 413 moves in the strip-shaped slot 421 from a position deviating from the center of the rotary disc 12 to the center of the rotary disc 12 when the clamping assembly 3 is in the first working condition.

[0104] In the above-mentioned embodiments, when the relative position of the rotary disc 12 and the base 11 is the preset position, and the clamping assembly 3 is in the first working condition, which is the correct use state of the child safety seat, the first mark 411 is located in the window 13. At this time, the slider 413 is located at the end of the strip-shaped slot 421 away from the rear side of the base 11, and the slider 413 deviates from the center of the rotary disc 12. Since the slider 413 deviates from the center of the rotary disc 12, during the rotation of the rotary disc 12 from the preset position relative to the base 11, the slider 413 moves in the strip-shaped slot 421 from a position deviating from the center of the rotary disc 12 to the center of the rotary disc 12, and the first mark 411 switches to the second mark 412.

[0105] Reference Figure 6 In some embodiments, a sliding groove 431 is arranged at the position where the first connecting member 43 is connected with the mark member 41, and part of the mark member 41 is located in the sliding groove 431 to realize the connection with the first connecting member 43. The mark member 41 is configured to move in the sliding groove 431 to approach or move away from the clamping assembly 3.

[0106] In the above-mentioned embodiments, when the clamping assembly 3 is switched from the first working condition to the second working condition, the clamping assembly 3 pulls the first connecting member 43 to move the first connecting member 43 to the rear side of the base 11. The clamping assembly 3 provides a force greater than the force provided by the second connecting member 44 through the first connecting member 43. The mark member 41 abuts against the side wall of the sliding groove 431 away from the clamping assembly 3, and the mark member 41 moves toward the clamping assembly 3 under the pulling force of the first connecting member 43. During the switching of the clamping assembly 3 from the second working condition to the first working condition, the clamping assembly 3 pushes the first connecting member 43 to move the first connecting member 43 to the front side of the base 11. The side wall of the sliding groove 431 close to the clamping assembly 3 moves toward the mark member 41 to release the pulling force on the mark member 41. At this time, the mark member 41 moves away from the clamping assembly 3 under the pulling force of the second connecting member 44.

[0107] Reference Figure 6In some embodiments, when the relative position of the rotary disc 12 and the base 11 is the preset position, and the clamping assembly 3 is in the first working condition, the identification member 41 is in abutment with the wall surface of the sliding groove 431 away from the clamping assembly 3.

[0108] In the first working condition of the clamping assembly 3, the first connecting member 43 releases the pulling force on the identification member 41, and the identification member 41 moves away from the clamping assembly 3 under the pulling force of the second connecting member 44, so that the identification member 41 is in abutment with the wall surface of the sliding groove 431 away from the clamping assembly 3.

[0109] In some embodiments, when the relative position of the rotary disc 12 and the base 11 is the preset position, the dimension of the sliding groove 431 in the front-rear direction of the base 11 is not less than the length of the strip-shaped groove 421. The maximum sliding stroke of the identification member 41 in the sliding groove 431 is not less than the maximum sliding stroke of the sliding block 413 in the strip-shaped groove 421, so that the identification member 41 can be prevented from being unable to translate relative to the rotary disc 12 due to the limitation of the first connecting member 43 on the identification member 41.

[0110] In some embodiments, the second connecting member 44 includes an elastic member. The elastic member includes a spring or the like.

[0111] In some embodiments, when the relative position of the rotary disc 12 and the base 11 is the preset position, and the clamping assembly 3 is in the first working condition, the identification member 41 moves away from the clamping assembly 3 under the pulling force of the second connecting member 44, so that the sliding block 413 is located at the end of the strip-shaped groove 421 away from the clamping assembly 3.

[0112] In the above-mentioned embodiments, when the relative position of the rotary disc 12 and the base 11 is the preset position, and the clamping assembly 3 is in the first working condition, the first connecting member 43 releases the pulling force on the identification member 41, and the identification member 41 moves away from the clamping assembly 3 under the pulling force of the second connecting member 44, so that the sliding block 413 is located at the end of the strip-shaped groove 421 away from the clamping assembly 3, and the sliding block 413 deviates from the center of the rotary disc 12.

[0113] In some embodiments, when the relative position of the rotary disc 12 and the base 11 is the preset position, and the clamping assembly 3 is in the second working condition, the clamping assembly 3 provides a force to the identification member 41 through the first connecting member 43, and overcomes the force of the second connecting member 44 on the identification member 41, so that the identification member 41 moves towards the clamping assembly 3, and the sliding block 413 is located at the end of the strip-shaped groove 421 close to the clamping assembly 3.

[0114] In the above-mentioned embodiments, when the relative position of the rotary disc 12 and the base 11 is the preset position, and the clamping assembly 3 is in the second working condition, the sliding block 413 is located at the center of the rotary disc 12.

[0115] In some embodiments, the linkage assembly 4 comprises an identification member 41 and a first connecting member 43.

[0116] The identification member 41 is movably arranged on the rotating disc 12, and the first identification 411 and the second identification 412 are arranged on the identification member 41.

[0117] The first connecting member 43 connects the identification member 41 and the clamping assembly 3. During the switching of the clamping assembly 3 from the first working condition to the second working condition, the first connecting member 43 provides a force to the identification member 41, so that the identification member 41 moves towards the clamping assembly 3.

[0118] In the above-mentioned embodiments, during the switching of the clamping assembly 3 from the first working condition to the second working condition, the first connecting member 43 provides a force to the identification member 41, so that the identification member 41 moves towards the clamping assembly 3, and thus the switching of the first identification 411 to the second identification 412 can be realized.

[0119] In some embodiments, the linkage assembly 4 further comprises a second connecting member 44, the second connecting member 44 connects the identification member 41 and the rotating disc 12, and the second connecting member 44 provides a force to the identification member 41 away from the clamping assembly 3; wherein the force provided by the first connecting member 43 to the identification member 41 is greater than the force provided by the second connecting member 44 to the identification member 41 when the clamping assembly 3 is in the second working condition.

[0120] In the above-mentioned embodiments, the relative position of the rotating disc 12 and the base 11 is a preset position, and when the clamping assembly 3 is in the first working condition, the first connecting member 43 releases the tension on the identification member 41, the identification member 41 moves away from the clamping assembly 3 under the tension of the second connecting member 44, the first identification 411 is located in the window 13, and during the switching of the clamping assembly 3 from the first working condition to the second working condition, the first connecting member 43 provides a force to the identification member 41, and the force provided by the first connecting member 43 to the identification member 41 is greater than the force provided by the second connecting member 44 to the identification member 41, so that the identification member 41 moves towards the clamping assembly 3. When the clamping assembly 3 is in the second working condition, the second identification 412 can be located in the window 13.

[0121] Reference Figure 8 and Figure 9 In some embodiments, the clamping assembly 3 comprises a clamping hook 31, the clamping hook 31 is connected to the first connecting member 43, the clamping hook 31 is configured to rotate and unlock the basket 2, so as to provide a force to the identification member 41 through the first connecting member 43, so that the identification member 41 moves towards the clamping assembly 3, and the clamping hook 31 is configured to rotate and lock the basket 2, so as to release the force provided by the first connecting member 43 to the identification member 41, so that the identification member 41 moves away from the clamping assembly 3.

[0122] In the above embodiment, the rotation of the clamping hook 31 drives the first connecting piece 43 to move relative to the rotating disc 12. In the process of the rotation of the clamping hook 31 and the unlocking of the basket 2, the first connecting piece 43 can be driven to move relative to the rotating disc 12 towards the clamping assembly 3. In the process of the rotation of the clamping hook 31 and the locking of the basket 2, the first connecting piece 43 can be driven to move relative to the rotating disc 12 away from the clamping assembly 3.

[0123] With reference to Figure 8 and Figure 9 In some embodiments, the clamping assembly 3 further comprises a connecting rod 32, the clamping hook 31 is rotationally connected with the rotating disc 12, the clamping hook 31 is fixedly connected with the connecting rod 32, the first connecting piece 43 is provided with a clamping groove, and the connecting rod 32 is arranged in the clamping groove.

[0124] In the above embodiment, the rotation of the clamping hook 31 drives the connecting rod 32 to move relative to the rotating disc 12, and the connecting rod 32 interacts with the clamping groove to drive the first connecting piece 43 to move relative to the rotating disc 12.

[0125] In some embodiments, the two ends of the connecting rod 32 are respectively provided with a clamping hook 31, the clamping hooks 31 at the two ends of the connecting rod 32 are symmetrically arranged, and the two clamping hooks 31 are both rotationally connected with the connecting frame 122. The connecting rod 32 is located in the clamping groove, and the two clamping hooks 31 are located outside the clamping groove.

[0126] In some embodiments, the clamping assembly 3 further comprises a locking piece 33, the locking piece 33 locks the clamping hook 31 after the rotation of the clamping hook 31 and the unlocking of the basket 2. When it is needed to rotate the clamping hook 31 to lock the basket 2, the locking of the clamping hook 31 by the locking piece 33 is released.

[0127] In some embodiments, the clamping hook 31 is provided with a recess, the locking piece 33 is located in the recess after the rotation of the clamping hook 31 and the unlocking of the basket 2, the locking piece 33 limits the rotation of the clamping hook 31 to achieve the locking of the clamping hook 31 by the locking piece 33. When it is needed to rotate the clamping hook 31 to lock the basket 2, the locking piece 33 is moved out of the recess, and the rotation of the clamping hook 31 is not limited, so that the locking of the clamping hook 31 by the locking piece 33 is released.

[0128] In the above embodiment, the specific implementation form of the movement of the locking piece 33 into or out of the recess can be realized by some related technologies, which will not be described herein.

[0129] With reference to Figure 4 , Figure 6 , Figure 8 and Figure 9 In some embodiments, the rotating disc 12 comprises a connecting frame 122 and a rotating body 121, the rotating body 121 is configured in a circular shape, the connecting frame 122 is connected with the rotating body 121, the clamping assembly 3 is arranged on the connecting frame 122, and the clamping assembly 3 is located at the radial outside of the rotating body 121.

[0130] In the above embodiment, the rotating body 121 is configured as a circle, and the center of the rotating disc 12 is the center of the circle of the rotating body 121. The clamping assembly 3 is arranged on the connecting frame 122, and the clamping assembly 3 is located on the radial outer side of the rotating body 121 and does not interfere with the basket 2.

[0131] In some embodiments, the rotating disc 12 further comprises an outer cover plate covering the rotating body 121 and the connecting frame 122, and the outer cover plate forms a mounting surface for mounting the basket 2.

[0132] In some embodiments, the clamping assembly 3 further comprises a connecting rod 32, a clamping groove is arranged in the first connecting piece 43, the connecting rod 32 is arranged in the clamping groove, the clamping hook 31 is fixedly connected with the connecting rod 32, and the clamping hook 31 is rotationally connected with the connecting frame 122. The rotationally connected part of the clamping hook 31 with the connecting frame 122 is different from the fixedly connected part of the clamping hook 31 with the connecting rod 32.

[0133] In the above embodiment, the clamping hook 31 rotates relative to the connecting frame 122, thereby driving the connecting rod 32 to move relative to the rotating disc 12. The connecting rod 32 moves the first connecting piece 43 relative to the rotating disc 12 through the interaction with the clamping groove.

[0134] In some embodiments, the identification member 41 is configured as a long strip structure, and in the state that the relative position of the rotating disc 12 and the base 11 is the preset position, the length extension direction of the identification member 41 is perpendicular to the front-back direction of the base 11, and the length extension direction of the identification member 41 is perpendicular to the directions of the first identification 411 to the second identification 412. The identification member 41 is arranged in the rotating disc 12, and under the guidance and limiting action of the guide member 42, the identification member 41 can only translate along the front-back direction of the rotating disc 12.

[0135] Here, in the state that the relative position of the rotating disc 12 and the base 11 is the preset position, the front-back direction of the rotating disc 12 is consistent with or opposite to the front-back direction of the base 11, and in the process that the rotating disc 12 rotates relative to the base 11 from the preset position, the front-back direction of the rotating disc 12 deviates from the front-back direction of the base 11. After the rotating disc 12 rotates 90 degrees relative to the base 11 from the preset position, the front-back direction of the rotating disc 12 is perpendicular to the front-back direction of the base 11.

[0136] Since the identification member 41 is movably arranged relative to the rotating disc 12, in the state that the relative position of the rotating disc 12 and the base 11 is the preset position, the identification member 41 can only translate along the front-back direction of the rotating disc 12 under the guidance and limiting action of the guide member 42; in the process that the rotating disc 12 rotates relative to the base 11, the identification member 41 rotates with the rotating disc 12 and can only translate along the front-back direction of the rotating disc 12, also under the guidance and limiting action of the guide member 42.

[0137] The following will be described in combination with the drawingsFigures 1 to 9 Some specific embodiments of the child safety seat are described in detail.

[0138] The child safety seat comprises a base assembly 1, a basket 2, a clamping assembly 3 and a linkage assembly 4. The base assembly 1 comprises a base 11 and a rotating disc 12. The clamping assembly 3 comprises a clamping hook 31, a connecting rod 32 and a locking piece 33. The linkage assembly 4 comprises an identification piece 41, a strip-shaped slot 421, a first connecting piece 43 and a second connecting piece 44.

[0139] The base 11 is provided with an annular guide structure. The middle part of the base 11 is provided with the strip-shaped slot 421, the length extension direction of the strip-shaped slot 421 is consistent with the front-back direction of the base 11, and the strip-shaped slot 421 is located on the left-right symmetry line of the annular guide structure. The rotating disc 12 comprises a rotating main body 121 and a connecting frame 122. The rotating main body 121 is configured as an annular structure, and the rotating main body 121 is matched with the annular guide structure on the base 11 to enable the rotating disc 12 to rotate relative to the base 11. The projection of the center of the rotating main body 121 on the base 11 falls within the strip-shaped slot 421, and is located at the end of the strip-shaped slot 421 close to the base 11. The connecting frame 122 comprises two first beams 1221 spaced apart and arranged in the rotating main body 121, and the length extension direction of the two first beams 1221 is consistent with the front-back direction of the base 11 in the state that the relative position of the rotating disc 12 and the base 11 is the preset position. The ends of the two first beams 1221 are respectively connected with second beams 1222, and the two second beams 1222 extend to the radial outside of the rotating main body 121 and the obliquely upper side of the rotating main body 121.

[0140] The identification piece 41 is configured as a long strip-shaped structure, and is movably arranged on the side of the two first beams 1221 away from the base 11. The identification piece 41 is arranged above the two first beams 1221. In the state that the relative position of the rotating disc 12 and the base 11 is the preset position, the length extension direction of the identification piece 41 is perpendicular to the length extension direction of the first beam 1221, and the end of the identification piece 41 in the length direction is provided with a first identification 411 and a second identification 412, and the first identification 411 is closer to the rear side of the base 11 relative to the second identification 412. The middle part of the side of the identification piece 41 facing the base 11 is provided with a sliding block 413, the sliding block 413 is located between the two first beams 1221 and is inserted into the strip-shaped slot 421.

[0141] The first end of the first connecting piece 43 is provided with a sliding groove 431, and the middle part of the identification piece 41 in the length direction is arranged in the sliding groove 431. In the state that the relative position of the rotating disc 12 and the base 11 is the preset position, the identification piece 41 can move in the sliding groove 431 to move forward and backward relative to the first connecting piece 43. The second end of the first connecting piece 43 extends between the two second beams 1222. The second end of the first connecting piece 43 is provided with a clamping groove.

[0142] The inner side of the two second beams 1222 is respectively rotationally provided with a hook 31. The two hooks 31 are symmetrically arranged, the second end of the first connecting piece 43 is located between the two hooks 31, and the two hooks 31 are fixedly connected with a connecting rod 32 arranged in the clamping groove. The two hooks 31 rotate relative to the two second beams 1222, drive the connecting rod 32 to move relative to the turntable 12, and the connecting rod 32 interacts with the clamping groove to drive the first connecting piece 43 to move relative to the turntable 12.

[0143] The two second connecting pieces 44 are respectively arranged on the side of the two first beams 1221 away from each other, the first end of the second connecting piece 44 is connected with the identification piece 41, and the second end of the second connecting piece 44 is connected with the turntable 12. In the state that the relative position of the turntable 12 and the base 11 is the preset position, the first connecting piece 43 extends to the rear side of the base 11, and the second connecting piece 44 extends to the front side of the base 11. The second connecting piece 44 provides the identification piece 41 with an acting force to move the identification piece 41 away from the clamping assembly 3. The second connecting piece 44 comprises an elastic piece, for example, a spring.

[0144] The clamping assembly 3 further comprises a locking piece 33. The hook 31 is provided with a groove, and after the hook 31 is rotated to be unlocked with the basket 2, the locking piece 33 is located in the groove. The locking piece 33 limits the rotation of the hook 31, and realizes the locking of the hook 31 by the locking piece 33. When the hook 31 needs to be rotated to be locked with the basket 2, the locking piece 33 is moved out of the groove, and does not limit the rotation of the hook 31, so that the locking of the hook 31 by the locking piece 33 is released.

[0145] Next, several key use states of the child safety seat will be described in combination with the structure of the child safety seat.

[0146] In the process of switching the clamping assembly 3 to the first working condition when the relative position of the turntable 12 and the base 11 is the preset position, the clamping hook 31 rotates to lock the basket 2. Due to the rotation of the clamping hook 31, the connecting rod 32 is driven to move to the front side of the base 11. The connecting rod 32 pushes the first connecting piece 43 to move to the front side of the base 11 through the clamping groove. Since the part where the first connecting piece 43 is connected with the marking piece 41 is provided with a sliding groove 431, the first connecting piece 43 can move to the front side of the base 11 relative to the marking piece 41. The first connecting piece 43 can not generate force to the marking piece 41. Due to the force of the second connecting piece 44, the second connecting piece 44 pulls the marking piece 41 away from the clamping assembly 3. The sliding block 413 of the marking piece 41 moves to the front side of the base 11 in the strip-shaped groove 421 until the sliding block 413 abuts against the end of the front side of the strip-shaped groove 421. The sliding block 413 deviates from the center of the turntable 12. At this time, the first marking 411 on the marking piece 41 is located in the window 13. The first marking 411 can be green. At this time, the window 13 displays green. Therefore, when the relative position of the turntable 12 and the base 11 is the preset position and the clamping assembly 3 is in the first working condition, the window 13 displays the first marking 411.

[0147] In the process of switching the clamping assembly 3 to the second working condition when the relative position of the turntable 12 and the base 11 is the preset position, the clamping hook 31 rotates to unlock the basket 2. Due to the rotation of the clamping hook 31, the connecting rod 32 is driven to move to the rear side of the base 11. The connecting rod 32 pulls the first connecting piece 43 to move to the rear side of the base 11 through the clamping groove. The first connecting piece 43 pulls the marking piece 41 to move to the rear side of the base 11 against the force of the second connecting piece 44. Until the sliding block 413 abuts against the end of the rear side of the strip-shaped groove 421, the sliding block 413 is located in the center of the turntable 12. At this time, the second marking 412 on the marking piece 41 is located in the window 13. The second marking 412 can be red. At this time, the window 13 displays red. Therefore, when the relative position of the turntable 12 and the base 11 is the preset position and the clamping assembly 3 is in the second working condition, the window 13 displays the second marking 412.

[0148] In the first working condition of the clamping assembly 3, during the process that the rotating disc 12 and the base 11 rotate from the preset position to the non-preset position, the slider 413 deviates from the center of the rotating disc 12 because the slider 413 abuts against the rear end of the strip-shaped slot 421, so that the rotating disc 12 drives the identification member 41 to rotate during the rotation of the rotating disc 12, the slider 413 deviates from the center of the strip-shaped slot 421, and the strip-shaped slot 421 pushes the slider 413 to move to the center of the rotating disc 12, so that the window 13 is switched from the first identification 411 to the second identification 412, and when the rotating disc 12 rotates 90 degrees from the preset position relative to the base 11, the first connecting member 43 and the second connecting member 44 are located on the left and right sides of the identification member 41, the first connecting member 43 and the second connecting member 44 cannot pull the identification member 41 because the strip-shaped slot 421 limits the identification member 41 in the left-right direction, and the second identification 412 is located in the window 13. Therefore, after the rotating disc 12 rotates 90 degrees from the preset position relative to the base 11 in the first working condition of the clamping assembly 3, the window 13 displays the second identification 412.

[0149] In the second working condition of the clamping assembly 3, the relative position of the rotating disc 12 and the base 11 is at the preset position, and the second identification 412 is located in the window 13, at this time, the slider 413 is located at the center of the rotating disc 12, the rotating disc 12 and the base 11 rotate 90 degrees from the preset position to the non-preset position, the first connecting member 43 and the second connecting member 44 are located on the left and right sides of the identification member 41, the first connecting member 43 and the second connecting member 44 cannot pull the identification member 41 because the strip-shaped slot 421 limits the identification member 41 in the left-right direction, and the second identification 412 is still located in the window 13. Therefore, after the rotating disc 12 rotates 90 degrees from the preset position relative to the base 11 in the second working condition of the clamping assembly 3, the window 13 displays the second identification 412.

[0150] Therefore, according to the description of each of the above embodiments, it can be known that the clamping assembly 3 and the linkage assembly 4 are related to each other, when the clamping assembly 3 is in the first working condition and the relative position of the rotating disc 12 and the base 11 is at the preset position, both conditions are met at the same time, the identification member 41 is displayed as green in the window 13, and other states are displayed as red.

[0151] Reference Figure 2 , the clamping assembly 3 is in the first working condition, and the relative position of the rotating disc 12 and the base 11 is at the preset position, the identification member 41 is displayed as green in the window 13. The rotating disc 12 can rotate relative to the base 11 to the left and right sides, and the rotation range is 90 degrees. The clamping assembly 3 is located at the rear side of the rotating disc 12 and is used for locking the matched basket 2.

[0152] Reference Figure 3 , the state of the rotating disc 12 rotating 90 degrees to the right from the preset position relative to the base 11, at this time, even if the clamping assembly 3 is in the first working condition, the identification member 41 is displayed as red in the window 13 because it does not meet the preset position.

[0153] The structure principle of the child safety seat is summarized as follows:

[0154] When the rotating disc 12 rotates 90 degrees laterally from the preset position relative to the base 11 (the clamping assembly 3 is in the first working condition), since a strip-shaped groove 421 is arranged on the base 11 along the center of the rotating disc 12 in the front-rear direction, the strip-shaped groove 421 is used to limit the identification member 41, so that the identification member 41 can only slide in the front-rear length direction of the strip-shaped groove 421 and cannot slide in the left-right direction of the strip-shaped groove 421. When the sliding block 413 of the identification member 41 is kept at the center position of the rotating disc 12, that is, at the rear end of the strip-shaped groove 421, the identification member 41 displays red in the window 13.

[0155] When the rotating disc 12 rotates to the preset position relative to the base 11 (the clamping assembly 3 is in the first working condition), under the action of the second connecting piece 44, the strip-shaped groove 421 on the base 11 guides the sliding block 413 to slide, so that the identification member 41 moves to the front side of the base 11, at this time, the window 13 is switched from red to green. The first connecting piece 43 is provided with a sliding groove 431, so that the identification member 41 can slide to switch the color display state.

[0156] When the clamping assembly 3 is in the second working condition, no matter the direction of the rotating disc 12, the window 13 always only displays red. The structure principle is as follows: when the clamping assembly 3 is in the second working condition, the clamping hook 31 is limited by the locking piece 33 and always keeps a static state. In the process of switching to the second working condition, the clamping hook 31 drives the identification member 41 to move to the rear side of the base 11 through the connecting rod 32 and the first connecting piece 43, until the window 13 displays red. At this time, even if the rotating disc 12 rotates to the left and right relative to the base 11, since the sliding block 413 on the identification member 41 cooperates with the strip-shaped groove 421 at this time, the sliding block 413 is just located at the center position of the rotating disc 12, the rotating action of the rotating disc 12 will not cause the sliding action of the identification member 41. Therefore, when the clamping assembly 3 is in the second working condition, the window 13 always only displays red.

[0157] Based on the above embodiments of the present application, one technical feature of one embodiment can be beneficially combined with one or more other embodiments without explicitly denying or conflicting.
