[0055] All terms used in this disclosure, including technical or scientific terms, have the same meaning as understood by one of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, such as a common dictionary, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0056] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0057] Child safety seats can be installed in vehicles to provide reliable safety protection for infants and toddlers. These vehicles can be cars, trains, ships, airplanes, or other modes of transportation.

[0058] In this disclosure, the directional terms "front" refer to the front side of the vehicle when it is in normal driving, "rear" refer to the rear side of the vehicle when it is in normal driving, "left" and "right" correspond to the left and right sides of the vehicle when it is in normal driving, respectively, and "up" and "down" correspond to the top and bottom of the vehicle when it is in normal driving, respectively.

[0059] Figure 1 This is a structural schematic diagram of some embodiments of child safety seats provided in this disclosure.

[0060] The child safety seat includes a base assembly 1 and an infant carrier 2. The base assembly 1 further includes a base 11 and a turntable 12, which is rotatable relative to the base 11. The infant carrier 2 is detachably mounted on the turntable 12. The infant carrier 2 is used to carry infants and toddlers. Since the base 11 is fixed after installation on the vehicle, its front-to-back direction and its left-to-right direction are aligned with the vehicle's front-to-back direction and the vehicle's left-to-right direction, respectively. Because the turntable 12 is rotatable relative to the base 11, it can be rotated as needed to face either the rear of the vehicle (the rear of the base 11) or the front of the vehicle (the front of the base 11).

[0061] The child safety seat also includes a locking assembly 3 mounted on the turntable 12. When the infant carrier 2 is installed on the turntable 12, the locking assembly 3 can lock the infant carrier 2, improving its stability on the turntable 12. When it is necessary to remove the infant carrier 2, the locking assembly 3 can be used to unlock the infant carrier 2.

[0062] To improve the safety of infants and toddlers in child safety seats, it is necessary to ensure that the carrier 2 faces the rear of the base 11, or that the carrier 2 faces the front of the base 11, and that the locking assembly 3 has locked the carrier 2. When both conditions are met, the child safety seat is considered to be in proper use.

[0063] Specifically, the correct position of the turntable 12 relative to the base 11 can be set to the rear side of the basket 2 facing the base 11, or the correct position of the turntable 12 relative to the base 11 can be set to the front side of the basket 2 facing the base 11. The term "preset position" in this disclosure refers to the correct position, including both of the above situations. Therefore, when the position of the turntable 12 relative to the base 11 is the preset position, the front-back direction of the turntable 12 is the same as the front-back direction of the base 11, or the front-back direction of the turntable 12 is opposite to the front-back direction of the base 11.

[0064] In practice, users cannot determine whether a child safety seat is in correct use by observation, or improper operation may result in the seat not being used correctly and going unnoticed, creating safety hazards. These hazards include: in the event of sudden braking or a collision, the carrier may detach, throwing the infant or toddler out along with the carrier, rendering the child safety seat ineffective.

[0065] Based on this, the present disclosure provides a child safety seat that can be used to promptly detect potential safety hazards in child safety seats.

[0066] refer to Figure 2 and Figure 3 In some embodiments, the child safety seat includes a base assembly 1, which includes a base 11 and a turntable 12. The turntable 12 is rotatably disposed on the base 11 and has a window 13. Optionally, the turntable 12 has windows 13 on its left and right sides or on one side.

[0067] The child safety seat also includes a locking assembly 3, which is located on the turntable 12. The locking assembly 3 includes a first working state and a second working state for respectively locking and unlocking with the carrier 2. That is, locking the locking assembly 3 with the carrier 2 is the first working state of the locking assembly 3; unlocking the locking assembly 3 with the carrier 2 is the second working state of the locking assembly 3.

[0068] refer to Figures 2 to 4 The child safety seat also includes a linkage component 4, which includes a first identifier 411 and a second identifier 412. The linkage component 4, in response to the relative position of the turntable 12 and the base 11 being in a preset position and the engaging component 3 being in a first working condition, positions the first identifier 411 in the window 13; the linkage component 4, in response to at least one of the relative position of the turntable 12 and the base 11 being in a non-preset position and the engaging component 3 being in a non-first working condition, positions the second identifier 412 in the window 13.

[0069] refer to Figure 2 The relative position of the turntable 12 and the base 11 is a preset position. When the locking component 3 is in the first working condition, that is, when the locking component 3 and the basket 2 are locked, the window 13 displays the first indicator 411.

[0070] refer to Figure 3 The turntable 12 rotates 90 degrees relative to the base 11. The relative position of the turntable 12 and the base 11 is not a preset position. At this time, regardless of whether the engaging component 3 is in the first working state or the second working state, the window 13 displays the second identifier 412. The turntable 12 can rotate 90 degrees clockwise or counterclockwise relative to the base 11.

[0071] Furthermore, when the relative position of the turntable 12 and the base 11 is a preset position, and the engaging component 3 is in the second working condition, the window 13 also displays the second identifier 412.

[0072] In other words, the child safety seat is considered to be in the correct usage state only when the relative position of the turntable 12 and the base 11 is in the preset position and the engaging component 3 is in the first working condition, and both conditions are met simultaneously. In this case, the window 13 displays the first indicator 411. In other cases where the correct usage state is not met, the window 13 displays the second indicator 412.

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

[0074] Therefore, users can determine whether the child safety seat is in the correct usage state based on the indicators displayed in window 13. If the child safety seat is not in the correct usage state, they can make timely checks and adjustments to avoid safety hazards.

[0075] refer to Figure 4 In some embodiments, the linkage component 4 includes an identifier 41 and a guide 42.

[0076] The identifier 41 is movably disposed on the turntable 12 and is configured to rotate with the turntable 12. A first identifier 411 and a second identifier 412 are disposed on the identifier 41.

[0077] The guide 42 is provided on the base 11 and is configured to guide and limit the marking 41.

[0078] In the above embodiment, the marker 41 is movably disposed on the turntable 12. The marker 41 is capable of translational movement relative to the turntable 12. Since the marker 41 is disposed on the turntable 12, the marker 41 can also rotate with the turntable 12 during the rotation of the turntable 12 relative to the base 11. Whether it is the translational movement of the marker 41 relative to the turntable 12 or the rotation of the marker 41 with the turntable 12, the marker 41 is guided and limited by the guide member 42. Therefore, it is beneficial to operably position the first marker 411 or the second marker 412 in the window 13.

[0079] refer to 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] With the turntable 12 and the base 11 in a preset relative position, one of the first connector 43 and the second connector 44 extends toward the rear of the base 11, while the other extends toward the front of the base 11.

[0089] In the above embodiment, when the relative position between the turntable 12 and the base 11 is a preset position, one of the first connector 43 and the second connector 44 extends to the rear side of the base 11, and the other extends to the front side of the base 11. The first connector 43 and the second connector 44 exert opposite forces on the identifier 41. Therefore, the identifier 41 can be moved towards or away from the engaging assembly 3 by the cooperation of the first connector 43 and the second connector 44, so as to place the first identifier 411 or the second identifier 412 in the window 13.

[0090] exist Figure 4 In the embodiment shown, the first connector 43 is connected to the identifier 41 and extends toward the rear side of the base 11, and the second connector 44 is connected to the identifier 41 and extends toward the front side of the base 11.

[0091] In some embodiments, the second connector 44 is configured to provide a force to the identifier 41 that moves the identifier 41 away from the engaging assembly 3; in a second operating condition, the engaging assembly 3 provides a force to the identifier 41 through the first connector 43 that moves the identifier 41 closer to the engaging assembly 3, and the force of the first connector 43 is greater than the force of the second connector 44; in a first operating condition, the engaging assembly 3 releases the force provided to the identifier 41 that moves the identifier 41 closer to the engaging assembly 3 through the first connector 43.

[0092] In the above embodiment, the relative position between the turntable 12 and the base 11 is a preset position. Under the first working condition, the locking component 3 releases the force provided to the marker 41 by the first connector 43 to bring the marker 41 closer to the locking component 3. The second connector 44 is configured to provide a force to the marker 41 to move the marker 41 away from the locking component 3. The second connector 44 pulls the marker 41 to translate relative to the turntable 12 and move it away from the locking component 3, so that the first marker 411 is located in the window 13.

[0093] With the turntable 12 and the base 11 in a preset position, in the second working condition, the engaging component 3 provides a force to the marker 41 through the first connector 43, causing the marker 41 to move closer to the engaging component 3, and the force of the first connector 43 is greater than the force of the second connector 44; the first connector 43 overcomes the force of the second connector 44, pulling the marker 41 to move relative to the turntable 12 and towards the engaging component 3, so that the second marker 412 is located in the window 13.

[0094] refer to Figure 4 In some embodiments, when the relative position between the turntable 12 and the base 11 is a preset position and the engaging component 3 is in the first working condition, the slider 413 is located at the end of the strip groove 421 away from the engaging component 3, and the slider 413 is offset from the center of the turntable 12.

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

[0096] When the relative position of the turntable 12 and the base 11 is at a preset position, and the engaging component 3 is in the first working condition, this is the correct usage state for the child safety seat. The first indicator 411 is located in the window 13. At this time, the slider 413 is located at the end of the strip groove 421 away from the engaging component 3, and the slider 413 is offset from the center of the turntable 12. Because the slider 413 is offset from the center of the turntable 12, during the rotation of the turntable 12, the strip groove 421 will push the slider 413 to move towards the center of the turntable 12. Therefore, during the process of the relative position of the turntable 12 and the base 11 changing to a non-preset position, the first indicator... 411 switches to the second identifier 412; after the turntable 12 rotates 90 degrees relative to the base 11 from the preset position, one of the first connector 43 and the second connector 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 groove 421 restricts the slider 413 from moving in the left and right direction along the base 11, the second connector 44 cannot pull the identifier 41 away from the locking assembly 3. Therefore, when the relative position of the turntable 12 and the base 11 is not the preset position, and the locking assembly 3 is in the first working condition, the second identifier 412 remains in the window 13.

[0097] In some embodiments, when the relative position between the turntable 12 and the base 11 is a preset position and the engaging component 3 is in the second working state, the slider 413 is located at the end of the strip groove 421 near the engaging component 3 and the slider 413 is located at the center of the turntable 12.

[0098] In the above embodiment, the relative position between the turntable 12 and the base 11 is a preset position, the engaging component 3 is in the first working state, the engaging component 3 releases the force provided to the marker 41 by the first connector 43 to bring the marker 41 closer to the engaging component 3, the second connector 44 is configured to provide a force to the marker 41 to move the marker 41 away from the engaging component 3, the second connector 44 pulls the marker 41 to move away from the engaging component 3, so that the first marker 411 is located in the window 13. At this time, the slider 413 is located at the end of the strip groove 421 away from the engaging component 3, and the slider 413 is deviated from the center of the turntable 12. When the engaging assembly 3 is in the second working state, the engaging assembly 3 provides a force to the marking member 41 through the first connector 43, which makes the marking member 41 move closer to the engaging assembly 3. The force of the first connector 43 is greater than the force of the second connector 44. The first connector 43 overcomes the force of the second connector 44 and pulls the marking member 41 to move closer to the engaging assembly 3, so that the second marking member 412 is located in the window 13. At this time, the slider 413 is located at the end of the strip groove 421 near the engaging assembly 3, and the slider 413 is located at the center of the turntable 12.

[0099] In some embodiments, when the turntable 12 is rotated 90 degrees relative to the base 11 from a preset position and the engaging assembly 3 is in a first working state, the slider 413 is located at the center of the turntable 12. Optionally, the slider 413 is located at the end of the strip groove 421 near the rear side of the base 11.

[0100] In some embodiments, when the turntable 12 is rotated 90 degrees relative to the base 11 from a preset position and the engaging assembly 3 is in the second working state, the slider 413 is located at the center of the turntable 12. Optionally, the slider 413 is located at the end of the strip groove 421 near the rear side of the base 11.

[0101] In the above embodiment, the relative position between the turntable 12 and the base 11 is a preset position, and the engaging component 3 is in the first working state, 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 groove 421 away from the rear side of the base 11, and the slider 413 is deviated from the center of the turntable 12. Since the slider 413 is deviated from the center of the turntable 12, during the rotation of the turntable 12, the strip groove 421 will push the slider 413 to move towards the center of the turntable 12. Therefore, during the process of the relative position between the turntable 12 and the base 11 changing to a non-preset position, the first mark 411 switches to the second mark 412. After the turntable 12 rotates 90 degrees relative to the base 11 from the preset position, the second mark 412 is located in the window 13, and the slider 413 is located at the center of the turntable 12. The slider 413 is located at the end of the strip groove 421 near the rear side of the base 11.

[0102] refer to Figure 7 When the turntable 12 rotates 90 degrees relative to the base 11 from a preset position, regardless of whether the engaging assembly 3 is in the first or second working condition, the slider 413 is located at the center of the turntable 12, and the second mark 412 is located in the window 13. Optionally, the slider 413 is located at the end of the strip groove 421 near the rear side of the base 11.

[0103] In some embodiments, when the engaging assembly 3 is in the first working condition, during the process of the turntable 12 rotating from a preset position relative to the base 11, the slider 413 moves within the strip groove 421 from a position off-center from the center of the turntable 12 toward the center of the turntable 12.

[0104] In the above embodiment, the relative position between the turntable 12 and the base 11 is a preset position, and the engaging component 3 is in the first working state, 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 groove 421 away from the rear side of the base 11, and the slider 413 is deviated from the center of the turntable 12. Since the slider 413 is deviated from the center of the turntable 12, during the process of the turntable 12 rotating relative to the base 11 from the preset position, the slider 413 moves from the position deviated from the center of the turntable 12 to the center of the turntable 12 in the strip groove 421, and the first mark 411 switches to the second mark 412.

[0105] refer to Figure 6 In some embodiments, a groove 431 is provided at the part where the first connector 43 is connected to the identifier 41, and a part of the identifier 41 is located in the groove 431 to achieve connection with the first connector 43. The identifier 41 is configured to move in the groove 431 to approach or move away from the engagement assembly 3.

[0106] In the above embodiment, the engaging assembly 3 switches from the first working condition to the second working condition. The engaging assembly 3 pulls the first connecting member 43, causing the first connecting member 43 to move towards the rear side of the base 11. The force provided by the engaging assembly 3 through the first connecting member 43 is greater than the force provided by the second connecting member 44. The marking member 41 abuts against the side wall of the slide groove 431 away from the engaging assembly 3. Under the pulling force of the first connecting member 43, the marking member 41 moves towards the engaging assembly 3. During the switching process of the engaging assembly 3 from the second working condition to the first working condition, the engaging assembly 3 pushes the first connecting member 43, causing the first connecting member 43 to move towards the front side of the base 11. The slide groove 431 moves towards the marking member 41 near the side wall of the engaging assembly 3, releasing the pulling force on the marking member 41. At this time, under the pulling force of the second connecting member 44, the marking member 41 moves away from the engaging assembly 3.

[0107] refer to Figure 6In some embodiments, the relative position of the turntable 12 and the base 11 is a preset position, and the engaging component 3 is in the first working state, with the marker 41 and the slide groove 431 abutting against the wall of the engaging component 3 away from each other.

[0108] When the engaging assembly 3 is in the first working condition, the first connector 43 releases the tension on the marking member 41. Under the tension of the second connector 44, the marking member 41 moves away from the engaging assembly 3, thus causing the marking member 41 to abut against the wall of the slide groove 431 away from the engaging assembly 3.

[0109] In some embodiments, when the relative position between the turntable 12 and the base 11 is at a preset position, the dimension of the slide groove 431 along the front-back direction of the base 11 is not less than the length of the strip groove 421. The maximum sliding stroke of the marker 41 in the slide groove 431 is not less than the maximum sliding stroke of the slider 413 in the strip groove 421. Therefore, it is possible to avoid the marker 41 being unable to translate relative to the turntable 12 due to the restriction imposed on it by the first connecting member 43.

[0110] In some embodiments, the second connector 44 includes an elastic element. The elastic element includes a spring, etc.

[0111] In some embodiments, the relative position of the turntable 12 and the base 11 is a preset position, and the engaging component 3 is in the first working condition. Under the pulling force of the second connecting member 44, the marker 41 moves away from the engaging component 3, so that the slider 413 is located at the end of the strip groove 421 away from the engaging component 3.

[0112] In the above embodiment, the relative position of the turntable 12 and the base 11 is a preset position, and the engaging component 3 is in the first working condition. The first connecting member 43 releases the tension on the marking member 41. Under the tension of the second connecting member 44, the marking member 41 moves away from the engaging component 3, so that the slider 413 is located at the end of the strip groove 421 away from the engaging component 3, and the slider 413 deviates from the center of the turntable 12.

[0113] In some embodiments, the relative position of the turntable 12 and the base 11 is a preset position, and the engaging component 3 is in the second working state. The engaging component 3 provides a force to the marking component 41 through the first connector 43 and overcomes the force of the second connector 44 on the marking component 41, so that the marking component 41 moves towards the engaging component 3, so that the slider 413 is located at the end of the strip groove 421 near the engaging component 3.

[0114] In the above embodiment, the relative position of the turntable 12 and the base 11 is a preset position, and the engaging component 3 is in the second working state, with the slider 413 located at the center of the turntable 12.

[0115] In some embodiments, the linkage component 4 includes an identifier 41 and a first connector 43.

[0116] The identification element 41 is movably disposed on the turntable 12, and a first identification element 411 and a second identification element 412 are disposed on the identification element 41.

[0117] The first connector 43 connects the marker 41 and the locking assembly 3. During the switching process from the first working condition to the second working condition, the locking assembly 3 provides a force to the marker 41 through the first connector 43, causing the marker 41 to move closer to the locking assembly 3.

[0118] In the above embodiment, during the switching process from the first working condition to the second working condition, the first connecting member 43 provides a force to the marking member 41, causing the marking member 41 to move closer to the locking component 3. Therefore, the switching from the first marking 411 to the second marking 412 can be realized.

[0119] In some embodiments, the linkage component 4 further includes a second connector 44, which connects the identifier 41 and the turntable 12, and the second connector 44 provides a force to the identifier 41 away from the engaging component 3; wherein, in the second working condition, the force provided by the engaging component 3 to the identifier 41 through the first connector 43 is greater than the force provided by the second connector 44 to the identifier 41.

[0120] In the above embodiment, the relative position of the turntable 12 and the base 11 is a preset position, and the engaging assembly 3 is in the first working state. The first connecting member 43 releases the tension on the marker 41, and the marker 41 moves away from the engaging assembly 3 under the tension of the second connecting member 44. The first marker 411 is located in the window 13. During the switching process from the first working state to the second working state, the engaging assembly 3 provides a force to the marker 41 through the first connecting member 43, and the force provided by the first connecting member 43 to the marker 41 is greater than the force provided by the second connecting member 44 to the marker 41, causing the marker 41 to move closer to the engaging assembly 3. In the second working state, the engaging assembly 3 can position the second marker 412 in the window 13.

[0121] refer to Figure 8 and Figure 9 In some embodiments, the locking assembly 3 includes a hook 31 connected to a first connector 43. The hook 31 is configured to rotate and unlock the basket 2 to provide a force to the identifier 41 via the first connector 43, causing it to move toward the locking assembly 3. The hook 31 is also configured to rotate and lock the basket 2 to release the force provided to the identifier 41 via the first connector 43, causing it to move toward the locking assembly 3.

[0122] In the above embodiment, the rotation of the hook 31 causes the first connecting member 43 to move relative to the turntable 12. During the process of the hook 31 rotating and unlocking the basket 2, the first connecting member 43 can move relative to the turntable 12 toward the engaging component 3. During the process of the hook 31 rotating and locking the basket 2, the first connecting member 43 can move relative to the turntable 12 away from the engaging component 3.

[0123] refer to Figure 8 and Figure 9 In some embodiments, the locking assembly 3 further includes a connecting rod 32, a hook 31 rotatably connected to the turntable 12, a hook 31 fixedly connected to the connecting rod 32, and a slot provided on the first connecting member 43, with the connecting rod 32 disposed in the slot.

[0124] In the above embodiment, the hook 31 rotates relative to the turntable 12, causing the connecting rod 32 to move relative to the turntable 12. The connecting rod 32 interacts with the slot to drive the first connecting member 43 to move relative to the turntable 12.

[0125] In some embodiments, a hook 31 is provided at each end of the connecting rod 32. The hooks 31 at both ends of the connecting rod 32 are symmetrically arranged, and both hooks 31 are rotatably connected to the connecting frame 122. The connecting rod 32 is located inside the slot, and the two hooks 31 are located outside the slot.

[0126] In some embodiments, the locking assembly 3 further includes a locking member 33, which locks the hook 31 after the hook 31 rotates and unlocks the basket 2. When it is necessary for the hook 31 to rotate and lock the basket 2, the locking member 33 releases the lock on the hook 31.

[0127] In some embodiments, the hook 31 is provided with a groove. After the hook 31 rotates and unlocks the basket 2, the locking member 33 is located in the groove, restricting the rotation of the hook 31 and thus locking the hook 31. When it is necessary for the hook 31 to rotate and lock the basket 2, the locking member 33 moves out of the groove, no longer restricting the rotation of the hook 31, and releasing the locking member 33 from locking the hook 31.

[0128] In the above embodiments, the specific implementation of the locking member 33 moving into or out of the groove can be achieved using some related technologies, which will not be elaborated in this disclosure.

[0129] refer to Figure 4 , Figure 6 , Figure 8 and Figure 9 In some embodiments, the turntable 12 includes a connecting frame 122 and a rotating body 121. The rotating body 121 is constructed to be circular. The connecting frame 122 connects to the rotating body 121. The engaging component 3 is disposed on the connecting frame 122 and is located on the radial outer side of the rotating body 121.

[0130] In the above embodiment, the rotating body 121 is constructed as a circle, and the center of the turntable 12 is the center of the rotating body 121. The engaging component 3 is disposed on the connecting frame 122, and the engaging component 3 is located on the radially outer side of the rotating body 121, so it will not interfere with the basket 2.

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

[0132] In some embodiments, the engaging assembly 3 further includes a connecting rod 32. A slot is provided within the first connecting member 43, and the connecting rod 32 is disposed within the slot. A hook 31 is fixedly connected to the connecting rod 32, and the hook 31 is rotatably connected to the connecting frame 122. The rotatable connection between the hook 31 and the connecting frame 122 differs from the fixed connection between the hook 31 and the connecting rod 32.

[0133] In the above embodiment, the hook 31 rotates relative to the connecting frame 122, causing the connecting rod 32 to move relative to the turntable 12. The connecting rod 32 interacts with the slot, causing the first connecting member 43 to move relative to the turntable 12.

[0134] In some embodiments, the marker 41 is constructed as an elongated strip structure. When the relative position of the turntable 12 and the base 11 is at a preset position, the length extension direction of the marker 41 is perpendicular to the front-back direction of the base 11, and the length extension direction of the marker 41 is perpendicular to the direction from the first marker 411 to the second marker 412. The marker 41 is disposed within the turntable 12, and under the guidance and limiting action of the guide member 42, the marker 41 can only translate along the front-back direction of the turntable 12.

[0135] Here, with the turntable 12 and base 11 in a preset relative position, the front-to-back direction of the turntable 12 is either the same as or opposite to the front-to-back direction of the base 11. During the rotation of the turntable 12 relative to the base 11 from the preset position, the front-to-back direction of the turntable 12 deviates from the front-to-back direction of the base 11. After the turntable 12 rotates 90 degrees relative to the base 11 from the preset position, the front-to-back direction of the turntable 12 becomes perpendicular to the front-to-back direction of the base 11.

[0136] Since the marker 41 can be translatably positioned relative to the turntable 12, when the relative position of the turntable 12 and the base 11 is in a preset position, the marker 41 can only translate along the front-back direction of the turntable 12 due to the guiding and limiting effect of the guide 42; during the rotation of the turntable 12 relative to the base 11, the marker 41 rotates with the turntable 12 due to the guiding and limiting effect of the guide 42, and can only translate along the front-back direction of the turntable 12.

[0137] The following is in conjunction with the appendix Figures 1 to 9 This section describes in detail some specific embodiments of child safety seats.

[0138] The child safety seat includes a base assembly 1, an infant carrier 2, a locking assembly 3, and a linkage assembly 4. The base assembly 1 includes a base 11 and a turntable 12. The locking assembly 3 includes a hook 31, a connecting rod 32, and a locking element 33. The linkage assembly 4 includes an identification element 41, a strip groove 421, a first connector 43, and a second connector 44.

[0139] The base 11 is provided with an annular guide structure. A strip groove 421 is provided in the middle of the base 11, the length of which extends in the same direction as the front-rear direction of the base 11. The strip groove 421 is located on the left-right symmetrical line of the annular guide structure. The turntable 12 includes a rotating body 121 and a connecting frame 122. The rotating body 121 is constructed as an annular shape and cooperates with the annular guide structure on the base 11 to allow the turntable 12 to rotate relative to the base 11. The projection of the center of the rotating body 121 onto the base 11 falls within the strip groove 421 and is located at the end of the strip groove 421 near the base 11. The connecting frame 122 includes two spaced-apart first beams 1221 disposed within the rotating body 121. In the relative position of the turntable 12 and the base 11 and in a preset position, the length of the two first beams 1221 extends in the same direction as the front-rear direction of the base 11. The ends of the two first beams 1221 are respectively connected to the second beams 1222, and the two second beams 1222 extend radially outward and obliquely upward towards the rotating body 121.

[0140] The marker 41 is constructed as a long strip structure and is movably disposed on the side of the two first beams 1221 opposite to the base 11. The marker 41 spans above the two first beams 1221. When the relative position of the turntable 12 and the base 11 is in a preset position, the length extension direction of the marker 41 is perpendicular to the length extension direction of the first beams 1221. The marker 41 has a first marker 411 and a second marker 412 at its length ends, with the first marker 411 closer to the rear side of the base 11 than the second marker 412. A slider 413 is located in the middle of the side of the marker 41 facing the base 11, positioned between the two first beams 1221 and inserted into the strip groove 421.

[0141] The first end of the first connector 43 is provided with a groove 431, and the middle part of the marker 41 along its length is disposed within the groove 431. When the relative position of the turntable 12 and the base 11 is at a preset position, the marker 41 can move within the groove 431 to move back and forth relative to the first connector 43. The second end of the first connector 43 extends between the two second beams 1222. The second end of the first connector 43 is provided with a slot.

[0142] Each of the two second beams 1222 has a hook 31 rotatably mounted on its inner side. The two hooks 31 are symmetrically arranged. The second end of the first connecting member 43 is located between the two hooks 31, and the two hooks 31 are fixedly connected to a connecting rod 32, which is disposed in a slot. The two hooks 31 rotate relative to the two second beams 1222, causing the connecting rod 32 to move relative to the turntable 12. The connecting rod 32 interacts with the slot to drive the first connecting member 43 to move relative to the turntable 12.

[0143] Two second connecting members 44 are respectively disposed on opposite sides of the two first beams 1221. The first end of each second connecting member 44 is connected to the identifier 41, and the second end is connected to the turntable 12. When the turntable 12 and the base 11 are in a preset relative position, the first connecting member 43 extends towards the rear of the base 11, and the second connecting member 44 extends towards the front of the base 11. The second connecting member 44 provides a force to the identifier 41, causing the identifier 41 to move away from the engaging assembly 3. The second connecting member 44 includes an elastic element, such as a spring.

[0144] The locking assembly 3 also includes a locking element 33. The hook 31 has a groove. After the hook 31 rotates and unlocks the basket 2, the locking element 33 is located in the groove, restricting the rotation of the hook 31 and thus locking the hook 31. When it is necessary for the hook 31 to rotate and lock the basket 2, the locking element 33 moves out of the groove, no longer restricting the rotation of the hook 31, and releasing the locking element 33 from locking the hook 31.

[0145] The following describes several key usage scenarios of child safety seats, taking into account their structure.

[0146] When the relative position between the turntable 12 and the base 11 is a preset position, during the switching process of the locking assembly 3 to the first working condition, the hook 31 rotates to lock with the basket 2. Due to the rotation of the hook 31, the connecting rod 32 moves towards the front of the base 11. The connecting rod 32 pushes the first connecting member 43 towards the front of the base 11 through the slot. Since the part where the first connecting member 43 connects with the label 41 is provided with a sliding groove 431, the first connecting member 43 can move towards the front of the base 11 relative to the label 41. The first connecting member 43 can not exert force on the label 41. However, due to the force of the second connecting member 44, the second connecting member 44 pulls the label 41 away from the locking assembly 3. The slider 413 of the label 41 moves towards the front of the base 11 in the strip groove 421 until the slider 413 abuts against the front end of the strip groove 421. The slider 413 deviates from the center of the turntable 12. At this time, the first label 411 on the label 41 is located in the window 13. The first identifier 411 can be set to green, at which point window 13 will display green. Therefore, when the relative position of turntable 12 and base 11 is the preset position and the engaging component 3 is in the first working condition, window 13 displays the first identifier 411.

[0147] When the relative position between the turntable 12 and the base 11 is at a preset position, during the switching process of the engaging assembly 3 to the second working state, the hook 31 rotates to unlock the basket 2. Due to the rotation of the hook 31, the connecting rod 32 moves towards the rear of the base 11. The connecting rod 32 pulls the first connecting member 43 towards the rear of the base 11 through the slot. The first connecting member 43 overcomes the force of the second connecting member 44 and pulls the marker 41 towards the rear of the base 11 until the slider 413 abuts against the rear end of the strip groove 421. The slider 413 is located at the center of the turntable 12. At this time, the second marker 412 on the marker 41 is located in the window 13. The second marker 412 can be set to red, and the window 13 is displayed in red. Therefore, when the relative position between the turntable 12 and the base 11 is at a preset position and the engaging assembly 3 is in the second working state, the window 13 displays the second marker 412.

[0148] In the first working condition of the locking assembly 3, as the turntable 12 and the base 11 rotate from the preset position to a non-preset position, the slider 413 abuts against the rear end of the strip groove 421, causing the slider 413 to deviate from the center of the turntable 12. Therefore, during the rotation of the turntable 12, the marker 41 rotates, and the slider 413 deviates from the center of the strip groove 421. The strip groove 421 pushes the slider 413 to move towards the center of the turntable 12. Therefore, the window 13 switches from the first marker 411 to the second marker 412. When the turntable 12 rotates 90 degrees relative to the base 11 from the preset position, the first connector 43 and the second connector 44 are located on the left and right sides of the marker 41. Since the strip groove 421 restricts the marker 41 in the left and right directions, neither the first connector 43 nor the second connector 44 can pull the marker 41, and the second marker 412 is located in the window 13. Therefore, in the first working condition of the locking assembly 3, after the turntable 12 rotates 90 degrees from the preset position relative to the base 11, the window 13 displays the second identifier 412.

[0149] In the second operating state of the engaging assembly 3, the relative position of the turntable 12 and the base 11 is at a preset position, and the second identifier 412 is located in the window 13. At this time, the slider 413 is located at the center of the turntable 12. After the turntable 12 and the base 11 rotate 90 degrees from the preset position to a non-preset position, the first connector 43 and the second connector 44 are located on the left and right sides of the identifier 41. Since the strip groove 421 restricts the identifier 41 in the left and right directions, neither the first connector 43 nor the second connector 44 can pull the identifier 41, and the second identifier 412 remains in the window 13. Therefore, in the second operating state of the engaging assembly 3, after the turntable 12 rotates 90 degrees from the preset position relative to the base 11, the window 13 displays the second identifier 412.

[0150] Therefore, based on the description of the above embodiments, it can be seen that the locking component 3 and the linkage component 4 are related to each other. When the locking component 3 is in the first working condition and the relative position of the turntable 12 and the base 11 is in the preset position, the identification element 41 is displayed in green in the window 13, and in other states it is displayed in red.

[0151] refer to Figure 2 In the first operating state, the locking component 3 is engaged, and the relative position of the turntable 12 and the base 11 is in a preset position, with the indicator 41 displayed in green in the window 13. The turntable 12 can rotate 90 degrees to the left and right relative to the base 11. The locking component 3 is located on the rear side of the turntable 12 and is used to lock the adapted basket 2.

[0152] refer to Figure 3 This refers to the state when the turntable 12 is rotated 90 degrees to the right relative to the base 11 from the preset position. At this time, even if the engaging component 3 is in the first working condition, the indicator 41 is displayed in red in the window 13 because it does not conform to the preset position.

[0153] The structural principles of child safety seats are summarized and explained below:

[0154] When the turntable 12 rotates 90 degrees to the side relative to the base 11 from a preset position (the engaging assembly 3 is in the first working condition), a strip groove 421 is set on the base 11 along the center of the turntable 12 in the forward-backward direction. The strip groove 421 is used to restrict the marker 41, so that the marker 41 can only slide in the forward-backward length direction of the strip groove 421, and cannot slide in the left-right direction of the strip groove 421. When the slider 413 of the marker 41 is held at the center position of the turntable 12, that is, at the rear end of the strip groove 421, the marker 41 is displayed in red in the window 13.

[0155] When the turntable 12 rotates relative to the base 11 to a preset position (the engaging component 3 is in the first working condition), under the action of the second connecting member 44, the strip groove 421 on the base 11 guides the slider 413 to slide, causing the indicator 41 to move towards the front of the base 11. At this time, the window 13 changes from red to green. The first connecting member 43 is provided with a sliding groove 431, which allows the indicator 41 to slide to switch the color display state.

[0156] When the engaging assembly 3 is in its second operating state, window 13 always displays only red, regardless of the orientation of the turntable 12. The structural principle is as follows: In the second operating state, the latch 31 is limited by the locking member 33 and remains stationary. During the transition to the second operating state, the latch 31, through the connecting rod 32 and the first connecting member 43, moves the marker 41 towards the rear of the base 11 until window 13 displays red. Even if the turntable 12 rotates left or right relative to the base 11, the slider 413 on the marker 41 engages with the strip groove 421, and the slider 413 is precisely positioned at the center of the turntable 12. Therefore, the rotation of the turntable 12 will not cause the marker 41 to slide. Thus, in the second operating state, window 13 always displays only red.
