[0081] 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.

[0082] In this utility model, the directional terms "front" refer to the front side of the vehicle when it is in normal driving mode, "rear" refer to the rear side of the vehicle when it is in normal driving mode, "left" and "right" correspond to the left and right sides of the vehicle when it is in normal driving mode, respectively, and "up" and "down" correspond to the top and bottom of the vehicle when it is in normal driving mode, respectively.

[0083] Figures 1 to 3 This is a structural schematic diagram of some embodiments of the child safety seat provided by this utility model.

[0084] refer to Figures 1 to 3 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. The turntable 12 is rotatable relative to the base 11 to adjust the relative position of the turntable 12 and the base 11, ensuring accurate positioning. 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, and the turntable 12 is rotatable relative to the base 11, the front-to-back direction of the base 11 aligns with the front-to-back direction of the vehicle, and the left-to-right direction of the base 11 aligns with the left-to-right direction of the vehicle.

[0085] refer to Figure 1 For infant passengers, users may want the infant to face the rear when riding in the vehicle. Therefore, the turntable 12 can be rotated so that the rear side of the turntable 12 is in front of the base 11, and the carrier 2 faces the rear of the vehicle (the rear side of the base 11).

[0086] refer to Figure 3 For young children, users may want the child to face forward when riding in the vehicle. Therefore, the turntable 12 can be rotated so that the rear side of the turntable 12 is located behind the base 11, and the basket 2 faces the front of the vehicle (the front side of the base 11).

[0087] The child safety seat also includes a locking assembly on the turntable 12. When the infant carrier 2 is installed on the turntable 12, the locking assembly can lock the infant carrier 2 in place, improving its stability on the turntable 12 and preventing it from detaching during sudden braking or a collision, thus avoiding the infant carrier 2 from being thrown out along with the infant and child occupant, rendering the child safety seat ineffective and creating a safety hazard. If it is necessary to remove the infant carrier 2, the locking assembly can be used to unlock it.

[0088] Since the infant carrier 2 can face the front or rear of the base 11, to improve the safety of infants and toddlers in the child safety seat, one requirement is to ensure that the carrier 2 faces the rear of the base 11 and that the engaging assembly is locked in place. When both conditions are met, the child safety seat is considered to be in a correct position. Another requirement is to ensure that the carrier 2 faces the front of the base 11 and that the engaging assembly is locked in place. When both conditions are met, the child safety seat is considered to be in another correct position.

[0089] In actual operation, users cannot determine whether a child safety seat is in the correct position by observation, or due to improper operation, there may be situations where the child safety seat is not in the correct position and goes unnoticed, resulting in safety hazards associated with the child safety seat.

[0090] Based on this, embodiments of the present invention provide a child safety seat that can promptly detect when a child safety seat is in an incorrect state.

[0091] refer to Figures 4 to 7 In some embodiments, the child safety seat includes a base assembly 1, a carrier 2, a first engaging assembly 3, and a linkage assembly 4.

[0092] The base assembly 1 includes a base 11 and a turntable 12. The turntable 12 is rotatably mounted on the base 11. The turntable 12 is provided with a window 13. Optionally, the turntable 12 is provided with windows 13 on its left and right sides or on one side.

[0093] Basket 2 is located on turntable 12.

[0094] The first locking component 3 is disposed on the turntable 12. The first locking component 3 includes a first working condition for locking with the basket 2 and a second working condition for unlocking with the basket 2. That is, the first working condition of the first locking component 3 is locking with the basket 2; the second working condition of the first locking component 3 is unlocking with the basket 2. Optionally, the first locking component 3 is disposed on the rear side of the turntable 12.

[0095] The linkage component 4 includes a first identifier 411 and a second identifier 412.

[0096] When the position of the turntable 12 relative to the base 11 is in the normal seating position and the first engagement component 3 is in the first working condition, the linkage component 4 is regarded as the correct state, and the first indicator 411 is displayed in the window 13; otherwise, the second indicator 412 is displayed in the window 13.

[0097] In some embodiments, the normal seating position includes the front side of the basket 2 facing the rear side of the base 11 and the front side of the basket 2 facing the front side of the base 11.

[0098] As the basket 2 rotates with the turntable 12, the front side of the basket 2 faces the rear side of the base 11, and the first engaging component 3 is in the first working condition. This state is regarded as the first correct state, and the first indicator 411 is displayed in the window 13.

[0099] As the basket 2 rotates with the turntable 12, the front side of the basket 2 faces the front side of the base 11, and the first engaging component 3 is in the first working condition. This state is regarded as the second correct state, and the first indicator 411 is displayed in the window 13.

[0100] In some embodiments, the front side of the basket 2 facing the rear side of the base 11 is used as a first normal seating position, and the front side of the basket 2 facing the front side of the base 11 is used as a second normal seating position.

[0101] The linkage component 4 responds to the relative position of the turntable 12 and the base 11 being in the first normal seating position, and the first engaging component 3 being in the first working condition, which is the first correct state, causing the first indicator 411 to be displayed in the window 13. (Reference) Figure 1 The relative position of turntable 12 and base 11 is the first normal seating position. When the first locking component 3 is in the first working condition, that is, when the first locking component 3 is locked with the basket 2, window 13 displays the first indicator 411.

[0102] The linkage component 4 responds to the relative position of the turntable 12 and the base 11 being in the second normal seating position, and the first engaging component 3 being in the first working condition, which is the second correct state, causing the first indicator 411 to be displayed in the window 13. (Reference) Figure 3 The relative position of the turntable 12 and the base 11 is the second normal seating position. When the first locking component 3 is in the first working condition, that is, when the first locking component 3 is locked with the basket 2, the window 13 displays the first indicator 411.

[0103] The linkage component 4, in response to neither the first correct state nor the second correct state, causes the second identifier 412 to be displayed in window 13. (See reference) Figure 2 The turntable 12 rotates 90 degrees relative to the base 11 from either the first or second normal seating position. When the relative position of the turntable 12 and the base 11 is neither the first nor the second normal seating position, the window 13 displays the second identifier 412 regardless of whether the first engaging component 3 is in the first or second working state. The turntable 12 can rotate clockwise or counterclockwise relative to the base 11.

[0104] In some embodiments, when the relative position of the turntable 12 and the base 11 is a first normal seating position or a second normal seating position, and the first engaging component 3 is in a second working condition, the window 13 also displays the second identifier 412.

[0105] In other words, the child safety seat is considered to be in its first correct state only when the relative position of the turntable 12 and the base 11 is in the first normal seating position and the first engaging component 3 is in the first working condition, and both conditions are met simultaneously. Window 13 then displays the first indicator 411. Similarly, the child safety seat is considered to be in its second correct state only when the relative position of the turntable 12 and the base 11 is in the second normal seating position and the first engaging component 3 is in the first working condition, and both conditions are met simultaneously. Window 13 then displays the first indicator 411.

[0106] In any other case where the first correct state and the second correct state are not met, window 13 displays the second identifier 412.

[0107] The relative position of the turntable 12 and the base 11 is the first normal seating position, which can be the front side of the turntable 12 being located behind the base 11, that is, the basket 2 facing the rear of the base 11. The relative position of the turntable 12 and the base 11 is the second normal seating position, which can be the front side of the turntable 12 being located in front of the base 11, that is, the basket 2 facing the front of the base 11. The turntable 12 rotates 180 degrees relative to the base 11 from the first normal seating position to the second normal seating position.

[0108] 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.

[0109] Therefore, users can determine whether the child safety seat is in the correct position based on the indicators displayed in window 13. If the child safety seat is not in the correct position, they can make timely checks and adjustments to avoid potential safety hazards.

[0110] refer to Figure 8 and Figure 9 In some embodiments, the child safety seat also includes a locking component 5, in a first correct state or a second correct state:

[0111] Locking component 5 is in the locked state, the position of turntable 12 and base 11 is relatively fixed, and the first mark 411 is displayed in window 13;

[0112] With the locking component 5 in the unlocked state, the turntable 12 can rotate relative to the base 11, and the second indicator 412 is displayed in the window 13.

[0113] In the above embodiment, the locking component 5 is used to lock the turntable 12 and the base 11 when the child safety seat is in the first correct state and the second correct state, so as to improve the safety of the child safety seat. At this time, the first indicator 411 is displayed in the window 13, which can also determine that the child safety seat is in the first correct state and the second correct state, and the locking component 5 is in the locked state.

[0114] When the child safety seat is in the first and second correct states, if the locking component 5 is in the unlocked state, the turntable 12 can rotate relative to the base 11, causing the second indicator 412 to be displayed in the window 13. Therefore, it can be used to remind the user to check whether the locking component 5 was accidentally unlocked, or whether the locking component 5 was indeed unlocked due to the need to rotate the turntable 12. In this case, it can remind the user to lock the locking component 5 after the turntable 12 is adjusted, locking the turntable 12 and the base 11 to improve the safety of the child safety seat.

[0115] refer to Figure 7 In some embodiments, the linkage component 4 includes an identifier 41, which is movably disposed on the turntable 12, and a first identifier 411 and a second identifier 412 are disposed on the identifier 41.

[0116] In the above embodiment, the marker 41 can move relative to the turntable 12. Since the marker 41 is located 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.

[0117] In some embodiments, the first identifier 411 is closer to the first engagement component 3 relative to the second identifier 412.

[0118] In some embodiments, the sign 41 is constructed as an elongated structure. When the relative position of the turntable 12 and the base 11 is a first normal seating position or a second normal seating position, the length extension direction of the sign 41 is perpendicular to the front-back direction of the base 11, and the length extension direction of the sign 41 is perpendicular to the direction from the first sign 411 to the second sign 412.

[0119] refer to Figure 8 and Figure 9 The locking component 5 includes a locking element 51, which is movably disposed on the turntable 12. The locking element 51 is configured to move relative to the turntable 12 during the transition from a locked state to an unlocked state, thereby causing the marker element 41 to move.

[0120] In the above embodiments, when the child safety seat is in the first correct state and the second correct state, if the locking member 51 is in the locked state, it locks the turntable 12 and the base 11, and at this time, the first indicator 411 is displayed in the window 13. During the process of the locking member 51 switching from the locked state to the unlocked state, the locking member 51 moves relative to the turntable 12, which can drive the indicator 41 to move, thus enabling the second indicator 412 to be displayed in the window 13. Through the process of the locking member 51 switching from the locked state to the unlocked state, the indicator 41 is linked, causing the window 13 to switch from the first indicator 411 to the second indicator 412.

[0121] refer to Figure 10 and Figure 11 In some embodiments, the locking member 51 is provided with a strip groove 511. In the first normal seating position or the second normal seating position, the length extension direction of the strip groove 511 is consistent with the front-rear direction of the base 11. The marking member 41 is provided with a slider 413 that inserts into the strip groove 511. The slider 413 moves along the strip groove 511, which enables the marking member 41 to translate relative to the turntable 12.

[0122] In the above embodiment, the locking member 51 is provided with a strip groove 511, and the marking member 41 is provided with a slider 413 that inserts into the strip groove 511. During the process of the locking member 51 moving relative to the turntable 12 and switching from the locked state to the unlocked state, the marking member 41 can be moved through the strip groove 511 to enable the window 13 to be operablely switched from the first marking 411 to the second marking 412.

[0123] In the above embodiments, in the first or second normal seating position, the length extension direction of the strip groove 511 is consistent with the front-rear direction of the base 11. The strip groove 511 restricts the slider 413, which can only move along the length extension direction of the strip groove 511, 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 511 in the left-right direction is slightly larger than the dimension of the slider 413 in the left-right direction.

[0124] refer to Figure 10 In some embodiments, when in a first or second correct state and the locking member 51 is in the locked state, the slider 413 is located at the end of the slot 511 away from the first engaging component 3. The first identifier 411 is displayed in window 13.

[0125] In the first correct state, the front side of the turntable 12 is located at the rear side of the base 11, that is, the basket 2 faces the rear side of the base 11. The first engaging component 3 is in the first working condition, that is, the first engaging component 3 is locked with the basket 2, the locking member 51 is in the locked state, and the position of the turntable 12 and the base 11 is fixed. At this time, the slider 413 is located at the end of the strip groove 511 away from the first engaging component 3, and the first mark 411 is displayed in the window 13.

[0126] In the second correct state, the front side of the turntable 12 is located on the front side of the base 11, that is, the basket 2 faces the front side of the base 11. The first engaging component 3 is in the first working condition, that is, the first engaging component 3 is locked with the basket 2, the locking member 51 is in the locked state, and the position of the turntable 12 and the base 11 is fixed. At this time, the slider 413 is located at the end of the strip groove 511 away from the first engaging component 3, and the first mark 411 is displayed in the window 13.

[0127] In some embodiments, during the process of switching the locking component 5 from a locked state to an unlocked state in either a first or second correct state, the locking member 51 pulls the slider 413 to move closer to the first engaging component 3. The first identifier 411 on the window 13 gradually switches to the second identifier 412.

[0128] In the above embodiment, when the locking component 5 is in the unlocked state, the slider 413 is located at the end of the strip groove 511 away from the first engaging component 3. However, since the locking component 51 pulls the slider 413 to move closer to the first engaging component 3, the second identifier 412 can be displayed in the window 13.

[0129] refer to Figure 11 In some embodiments, the relative positions of the turntable 12 and the base 11 are either a first normal seating position or a second normal seating position, and when the first engaging assembly 3 is in the second operating condition, if the locking member 51 is in the locked state, the slider 413 is located at the end of the strip groove 511 near the first engaging assembly 3. If the locking member 51 is in the unlocked state, the slider 413 is located at the end of the strip groove 511 away from the first engaging assembly 3.

[0130] In the above embodiment, the relative position of the turntable 12 and the base 11 is either the first normal seating position or the second normal seating position, and the first engaging component 3 switches from the first working condition to the second working condition. The marker 41 moves toward the first engaging component 3, and the window 13 switches from the first marker 411 to the second marker 412. At this time, the locking component 51 is in the locked state, and the slider 413 is located at the end of the strip groove 511 near the first engaging component 3. If the locking component 51 switches from the locked state to the unlocked state, the locking component 51 moves toward the first engaging component 3, and the slider 413 is located at the end of the strip groove 511 away from the first engaging component 3.

[0131] refer to Figure 12 and Figure 13 In some embodiments, the locking component 5 includes a locking member 51, which is movably disposed on the turntable 12. The bottom of the locking member 51 is provided with a locking part 512, and the base 11 is provided with a locking groove 111. The locking member 51 moves relative to the turntable 12 so that the locking part 512 is located in the locking groove 111, thereby locking the turntable 12 and the base 11. The locking member 51 moves relative to the turntable 12 so that the locking part 512 disengages from the locking groove 111, thereby unlocking the turntable 12 and the base 11.

[0132] In the above embodiment, the locking part 512 is located in the locking groove 111 and can limit the turntable 12 and the base 11. The turntable 12 cannot rotate relative to the base 11. After the locking part 51 moves relative to the turntable 12 and the locking part 512 is disengaged from the locking groove 111, the turntable 12 is unlocked from the base 11 and the turntable 12 can rotate relative to the base 11.

[0133] refer to Figure 12 The locking element 51 is located on the side of the turntable 12 near the first engaging assembly 3. Optionally, the locking element 51 and the first engaging assembly 3 are located on the rear side of the turntable 12.

[0134] refer to Figure 13 A locking groove 111 is provided on the front and rear sides of the base 11, so that when the turntable 12 is rotated from the rear side to the front side of the base 11, and when the turntable 12 is rotated from the rear side to the rear side of the base 11, the corresponding locking groove 111 on the base 11 cooperates with the locking part 512 on the locking member 51.

[0135] refer to Figures 8 to 11 In some embodiments, the locking assembly 5 further includes a first elastic member 52, which connects the locking member 51 and the turntable 12. The locking member 51 is configured to move against the force of the first elastic member 52 under the action of an external force, so that the locking part 512 disengages from the locking groove 111. The locking member 51 is also configured to move under the force of the first elastic member 52 when the external force is released, so that the locking part 512 is located in the locking groove 111.

[0136] In the above embodiments, reference is made to Figure 8 Locking element 51 is in the locked state, and first elastic element 52 is in the retracted state, tightening locking element 51 and turntable 12. (Reference) Figure 9 Under the action of external force, the locking member 51 moves relative to the turntable 12 towards the first engaging component 3, and the locking member 51 is in the unlocked state, while the first elastic member 52 is stretched. After the external force is removed, the restoring force provided by the first elastic member 52 can cause the locking member 51 to move away from the first engaging component 3, so that the locking member 51 returns to the locked state.

[0137] In some embodiments, the first elastic element 52 includes a spring.

[0138] In some embodiments, the locking assembly 5 further includes a lever 53 and a knob 54, the lever 53 connecting the locking member 51 and the knob 54, the knob 54 being located outside the turntable 12, and the lever 53 and the locking member 51 being located inside the turntable 12.

[0139] In the above embodiment, the knob 54 is located outside the turntable 12, which makes it convenient for the user to apply force through the knob 54, so that the knob 54 drives the locking member 51 to move relative to the turntable 12 through the pull rod 53, thereby unlocking the locking member 51.

[0140] In some embodiments, the knob 54 is configured to rotate along the turntable 12 to convert the pull rod 53 into translational motion of the locking member 51 relative to the turntable 12 in the front-back direction.

[0141] refer to Figure 7 In some embodiments, the linkage component 4 further includes an identifier 41 and a latching handle 42, which are movably disposed on the turntable 12. The identifier 41 is provided with a first identifier 411 and a second identifier 412. The latching handle 42 connects the identifier 41 and the first latching component 3.

[0142] The latch handle 42 is configured to move away from the first latch assembly 3 so that the first latch assembly 3 switches from the second working condition to the first working condition, and the latch handle 42 drives the marker 41 to move away from the first latch assembly 3.

[0143] The latch handle 42 is configured to move toward the first latching assembly 3 so that the first latching assembly 3 switches from a first working condition to a second working condition, and the latch handle 42 drives the marker 41 to move toward the first latching assembly 3.

[0144] In the above embodiments, since the latch handle 42 connects the identifier 41 and the first latching assembly 3, as the latch handle 42 moves away from the first latching assembly 3, it can drive the first latching assembly 3 to switch from the second working condition to the first working condition. Furthermore, the latch handle 42 can also drive the identifier 41 to move away from the first latching assembly 3, causing the second identifier 412 to leave the window 13 and the first identifier 411 to be displayed in the window 13. Conversely, as the latch handle 42 moves closer to the first latching assembly 3, it can drive the first latching assembly 3 to switch from the first working condition to the second working condition, and it can also drive the identifier 41 to move closer to the first latching assembly 3, causing the first identifier 411 to leave the window 13 and the second identifier 412 to be displayed in the window 13.

[0145] refer to Figure 14In some embodiments, the linkage component 4 further includes a second elastic member 43. The latching handle 42 is provided with a groove 421. A portion of the marking member 41 is located in the groove 421. The second elastic member 43 is pressed into the groove 421. The first end of the second elastic member 43 abuts against the marking member 41, and the second end of the second elastic member 43 abuts against the side wall of the groove 421 near the first latching component 3. The marking member 41 is configured to move within the groove 421 to approach or move away from the first latching component 3.

[0146] In the above embodiment, under the action of external force, the locking member 51 moves towards the first engaging component 3. During the process of switching from the locked state to the unlocked state, the locking member 51 drives the marking member 41 to move towards the first engaging component 3 against the elastic force of the second elastic member 43, so that the window 13 changes from the first marking 411 to the second marking 412. When the external force on the locking member 51 is removed, the locking member 51 is pulled away from the first engaging component 3 under the action of the elastic force of the first elastic member 52, and the locking member 51 resets. During the process of switching from the unlocked state to the locked state, the marking member 41 also moves away from the first engaging component 3 under the action of the elastic force of the second elastic member 43, and the marking member 41 resets, so that the window 13 changes from the second marking 412 to the first marking 411.

[0147] In some embodiments, the second elastic element 43 includes a spring.

[0148] refer to Figure 6 , Figure 10 and Figure 11 In some embodiments, the linkage component 4 further includes a third elastic element 44, which connects the latching handle 42 and the turntable 12; the third elastic element 44 provides a force to the latching handle 42 to move it away from the first latching component 3.

[0149] In the above embodiment, when an external force is applied, the latch handle 42 can overcome the elastic force of the third elastic member 44 and move towards the first latching assembly 3; after the external force is removed, the third elastic member 44 provides elastic force, which enables the latch handle 42 to move away from the first latching assembly 3.

[0150] In some embodiments, the third elastic element 44 includes a spring.

[0151] refer to Figure 15 and Figure 16 In some embodiments, the first engaging component 3 includes a first hook 31, which is rotatably connected to the turntable 12; the engaging handle 42 is provided with a protrusion 422, which passes through and connects the first hook 31 and the turntable 12.

[0152] The locking handle 42 moves away from the first locking component 3, and the protrusion 422 drives the first hook 31 to rotate relative to the turntable 12, thereby locking the first hook 31 with the basket 2.

[0153] The locking handle 42 moves toward the first locking component 3, and the protrusion 422 drives the first hook 31 to rotate relative to the turntable 12, thereby locking the first hook 31 with the basket 2.

[0154] In the above embodiment, the first hook 31 is located between the engaging handle 42 and the turntable 12. The first hook 31 is rotatably connected to the turntable 12 via a hinge 124. The protrusion 422 on the engaging handle 42 passes through the first hook 31 and the turntable 12 in sequence. The translational movement of the engaging handle 42 relative to the turntable 12 can be converted into the rotation of the first hook 31 relative to the turntable 12. The rotation of the first hook 31 can engage and lock with the basket 2 or release the engagement and locking mechanism with the basket 2.

[0155] In some embodiments, with a first normal seating position or a second normal seating position as a reference, the turntable 12 is provided with a first strip hole 1221 extending in the front-back direction of the base 11; the first hook 31 is provided with a second strip hole 312 extending in the up-down direction of the base 11, and the protrusion 422 is sequentially inserted into the second strip hole 312 and the first strip hole 1221.

[0156] In the above embodiment, with the first normal seating position or the second normal seating position as a reference, the first strip hole 1221 extends along the front-back direction of the base 11 and can guide the translation of the latching handle 42 relative to the turntable 12. The second strip hole 312 extends along the up-down direction of the base 11 and can guide the rotation of the first hook 31 relative to the turntable 12.

[0157] refer to Figure 16 In some embodiments, the first engaging component 3 further includes a first limiting member 32 and a fourth elastic member 33.

[0158] The first limiting member 32 is movably provided on the turntable 12.

[0159] The fourth elastic element 33 abuts against the first limiting element 32 and the turntable 12 respectively.

[0160] The first limiting member 32 is configured to abut against the first hook 31 under the action of the fourth elastic member 33 to restrict the rotation of the first hook 31. The first limiting member 32 is configured to squeeze the fourth elastic member 33 and disengage from the first hook 31 under the action of external force to release the limitation on the first hook 31.

[0161] In the above embodiment, the elastic force provided by the fourth elastic element 33 causes the first limiting element 32 to abut against the first hook 31, preventing the first hook 31 from rotating. At this time, even if the locking handle 42 is pushed, it cannot move because the first hook 31 cannot rotate. Applying a force to the first limiting element 32 compresses the fourth elastic element 33, causing it to move downwards. The first limiting element 32 disengages from the first hook 31 and no longer limits its movement. Therefore, the movement of the locking handle 42 can drive the rotation of the first hook 31, thus locking or unlocking the locking handle 42 and the basket 2.

[0162] In some embodiments, the fourth elastic element 33 includes a spring.

[0163] In some embodiments, the child safety seat further includes a second engaging component 6, which is disposed opposite to the first engaging component 3.

[0164] The second locking component 6 includes a second hook 61, a second limiting member 62, and a fifth elastic member 63.

[0165] The second hook 61 is located on the locking handle 42 and is used to lock or unlock the basket 2.

[0166] The second limiting member 62 is movably provided on the turntable 12.

[0167] The fifth elastic element 63 abuts against the second limiting element 62 and the turntable 12 respectively.

[0168] The second limiting member 62 is configured to abut against the second hook 61 under the action of the fifth elastic member 63 to restrict the movement of the second hook 61. The second limiting member 62 is configured to squeeze the fifth elastic member 63 and disengage from the second hook 61 under the action of external force to release the limitation on the second hook 61.

[0169] In the above embodiments, the second engaging component 6 is disposed opposite to the first engaging component 3. Optionally, the first engaging component 3 is disposed on the rear side of the turntable 12 and the second engaging component 6 is disposed on the front side of the turntable 12, or the first engaging component 3 is disposed on the front side of the turntable 12 and the second engaging component 6 is disposed on the rear side of the turntable 12.

[0170] In the above embodiment, the elastic force provided by the fifth elastic member 63 causes the second limiting member 62 to abut against the second hook 61, preventing the second hook 61 from moving. At this time, even if the locking handle 42 is pushed, it cannot move because the second hook 61 cannot move. Applying a force to the second limiting member 62 compresses the fifth elastic member 63, causing it to move downwards. The second limiting member 62 disengages from the second hook 61, releasing the restriction on the second hook 61. Then, the movement of the locking handle 42 can drive the second hook 61 to move, thus locking or unlocking the second hook 61 with the basket 2.

[0171] In some embodiments, the fifth elastic element 63 includes a spring.

[0172] refer to Figure 5 In some embodiments, the child safety seat also includes an infant carrier 2, the bottom of which is provided with a first latching member 21 and a second latching member 22, which are respectively latched to a first hook 31 and a second hook 61.

[0173] The second locking member 22 and the first locking member 21 are respectively located on the front and rear sides of the basket 2. During the process of installing the basket 2 onto the turntable 12, the first locking member 21 and the second locking member 22 at the bottom of the basket 2 respectively press down on the first limiting member 32 and the second limiting member 62, releasing the restriction on the first hook 31 and the second hook 61. At this time, the locking handle 42 moves away from the first locking assembly 3 under the elastic force of the third elastic member 44. The first hook 31 rotates and locks with the first locking member 21, and the second hook 61 moves away from the first locking assembly 3 and locks with the second locking member 22.

[0174] In some embodiments, the basket 2 is further provided with an unlocking component 23, which is connected to the locking handle 42. Pulling the unlocking component 23 causes the locking handle 42 to move closer to the first locking assembly 3, disengaging the second hook 61 from the second locking member 22. The elastic force provided by the fifth elastic member 63 causes the second limiting member 62 to abut against the second hook 61, preventing the second hook 61 from moving. At this time, the locking handle 42 cannot move. Simultaneously, the first hook 31 also rotates and unlocks from the first locking member 21, allowing the basket 2 to be removed. The elastic force provided by the fourth elastic member 33 causes the first limiting member 32 to abut against the first hook 31, restricting the rotation of the first hook 31.

[0175] refer to Figure 6 In some embodiments, the turntable 12 includes an outer cover plate 121, a support beam 123, and a first support frame 122.

[0176] The support beam 123 is located between the outer cover plate 121 and the base 11, and extends along the front-rear direction of the base 11 (with reference to the first normal seating position and the second normal seating position).

[0177] The first support frame 122 is located between the outer cover plate 121 and the base 11. The first support frame 122 is connected to the support beam 123 and extends obliquely upward to the base 11. The first engaging component 3 is located on the first support frame 122.

A first engaging component 3 is disposed between one side of the latching handle 42 and one first support frame 122, and another first engaging component 3 is disposed between the other side of the latching handle 42 and the other first support frame 122. The latching handle 42 can move back and forth relative to the turntable 12. (Reference) Figure 10 and Figure 11 The third elastic element 44 connects the latching handle 42 and the turntable 12. Under the action of external force, the latching handle 42 can overcome the elastic force of the third elastic element 44 and move towards the first latching assembly 3. After the external force is removed, the latching handle 42 can also move away from the first latching assembly 3 under the action of the elastic force of the third elastic element 44.

[0189] refer to Figure 7 The marker 41 is also a strip-shaped component, located at the top of the two support beams 123 and at the bottom of the latching handle 42. The length extension direction of the marker 41 is perpendicular to the length extension direction of the support beams 123. One end of the marker 41 has a first marker 411 and a second marker 412. Alternatively, both ends of the marker 41 have a first marker 411 and a second marker 412. The first marker 411 is closer to the first latching assembly 3 than the second marker 412. The marker 41 can translate relative to the turntable 12 and also relative to the latching handle 42.

[0190] refer to Figure 14The bottom of the latching handle 42 is provided with a groove 421. A portion of the marking element 41 is located within the groove 421. The marking element 41 slides within the groove 421 to move towards or away from the first latching assembly 3. A second elastic element 43 is pressed and disposed within the groove 421. One end of the second elastic element 43 abuts against the marking element 41, and the other end of the second elastic element 43 abuts against the side wall of the groove 421 near the first latching assembly 3. The marking element 41 can slide within the groove 421 against the force of the second elastic element 43 to move towards the first latching assembly 3; the marking element 41 can also slide within the groove 421 under the force of the second elastic element 43 to move away from the first latching assembly 3.

One end of the fourth elastic member 33 abuts against the first limiting member 32, and the other end of the fourth elastic member 33 abuts against the second support frame 125. Under the elastic force of the fourth elastic member 33, the first limiting member 32 abuts against the first hook 31, thereby limiting the first hook 31 and preventing it from rotating.

[0194] Since the two ends of the latch handle 42 are respectively provided with the first latching components 3, the two first limiting members 32 can be connected by the first connecting member. Under the action of external force, the two first limiting members 32 squeeze the fourth elastic member 33, and the two first limiting members 32 and the first connecting member move down at the same time, releasing the limitation on the first hook 31. After the external force is removed, the elastic force of the fourth elastic member 33 pushes the two first limiting members 32 to move upward, and at the same time the first connecting member moves upward. The first connecting member or the two first limiting members 32 can respectively latch and limit the two first hooks 31.

[0195] The second engaging component 6 is disposed opposite to the first engaging component 3. The first engaging component 3 is disposed on the rear side of the turntable 12, and the second engaging component 6 is disposed on the front side of the turntable 12. The second engaging component 6 includes a second hook 61, a second limiting member 62, and a fifth elastic member 63.

[0196] The second hook 61 is provided on the latch handle 42 and is located at the front end of the latch handle 42. The second limiting member 62 and the fifth elastic member 63 are also located on the front side of the turntable 12.

[0197] The turntable 12 also includes a third support frame 126, the position of which corresponds to the position of the second engaging assembly 6. One end of the fifth elastic member 63 abuts against the second limiting member 62, and the other end of the fifth elastic member 63 abuts against the third support frame 126. Under the elastic force of the fifth elastic member 63, the second limiting member 62 abuts against the second hook 61, thereby limiting the second hook 61 and preventing it from moving.

[0198] Since the two ends of the latch handle 42 are respectively provided with second latching components 6, the two second limiting members 62 can be connected by the second connecting member. Under the action of external force, the two second limiting members 62 squeeze the fifth elastic member 63. The two second limiting members 62 and the second connecting member move down at the same time, releasing the limitation on the second hook 61. After the external force is removed, the elastic force of the fifth elastic member 63 pushes the two second limiting members 62 to move upward. At the same time, the second connecting member moves upward. The two second limiting members 62 or the second connecting member can respectively latch and limit the two second hooks 61.

[0199] refer to Figure 5 The bottom of the basket 2 is provided with a first locking member 21 and a second locking member 22. The first locking member 21 and the second locking member 22 are respectively engaged with the first hook 31 and the second hook 61.

[0200] During the installation of the basket 2 onto the turntable 12, the first locking member 21 at the bottom of the basket 2 presses down on the first limiting member 32, which in turn presses down on the fourth elastic member 33. Both first limiting members 32 and the first connecting member move downwards simultaneously, releasing the restriction on the first hook 31. The second locking member 22 at the bottom of the basket 2 presses down on the second limiting member 62, which in turn presses down on the fifth elastic member 63. Both second limiting members 62 and the second connecting member move downwards simultaneously, releasing the restriction on the second hook 61. Under the elastic force of the third elastic member 44, the locking handle 42 moves away from the first locking assembly 3, causing the first hook 31 to rotate and lock the first locking member 21. Because the locking handle 42 moves away from the first locking assembly 3, the second hook 61 also moves away from the first locking assembly 3, locking with the second locking member 22. Therefore, the basket 2 is locked in place by the first locking assembly 3 and the second locking assembly 6.

[0201] The basket 2 is also equipped with an unlocking component 23, which is connected to the locking handle 42. Pulling the unlocking component 23 causes the locking handle 42 to move closer to the first locking component 3, disengaging the second hook 61 from the second locking member 22. The elastic force provided by the fifth elastic member 63 causes the second limiting member 62 to abut against the second hook 61, preventing the second hook 61 from moving. At this time, the locking handle 42 cannot move. Simultaneously, the first hook 31 also rotates and unlocks from the first locking member 21, allowing the basket 2 to be removed. The elastic force provided by the fourth elastic member 33 causes the first limiting member 32 to abut against the first hook 31, restricting the rotation of the first hook 31.

[0202] refer to Figure 8 and Figure 9 The locking assembly 5 includes a locking member 51, a first elastic member 52, a pull rod 53, and a knob 54.

[0203] A locking element 51 is movably mounted on the turntable 12. A first elastic element 52 connects the locking element 51 and the turntable 12, and a pull rod 53 connects the locking element 51 and the knob 54. The pull rod 53 and the locking element 51 are located inside the outer cover plate 121 of the turntable 12, while the knob 54 is located outside the outer cover plate 121 of the turntable 12. This allows the user to apply force through the knob 54, causing it to move the locking element 51 relative to the turntable 12 via the pull rod 53, thus unlocking the locking element 51. A locking part 512 is provided at the bottom of the locking element 51. When the locking part 512 is located within the locking groove 111 of the base 11, the locking element 51 is in a locked state, and the first elastic element 52 is in a retracted state, tightening the locking element 51 and the turntable 12. When a force is applied to the knob 54, the lever 53 moves the locking member 51 relative to the base 11 towards the first engaging assembly 3, causing the locking part 512 to disengage from the locking groove 111. The first elastic member 52 is then stretched, unlocking the locking member 51. When the force on the knob 54 is released, the restoring force provided by the first elastic member 52 moves the locking member 51 away from the first engaging assembly 3, and the locking part 512 is positioned within the locking groove 111 of the base 11, restoring the locking member 51 to its locked state.

[0204] The locking component 51 is also provided with a strip groove 511. The length extension direction of the strip groove 511 is consistent with the front and rear direction of the turntable 12. The bottom of the marking component 41 is provided with a slider 413, which is inserted into the strip groove 511.

[0205] When a force is applied to the knob 54, causing the lever 53 to move the locking member 51 relative to the base 11 towards the first engaging assembly 3, the strip groove 511 pulls the slider 413 to press the second elastic member 43 towards the first engaging assembly 3. After the force on the knob 54 is released, the restoring force provided by the first elastic member 52 causes the locking member 51 to move away from the first engaging assembly 3. The locking part 512 is located within the locking groove 111 of the base 11, restoring the locking member 51 to its locked state. Under the restoring force of the second elastic member 43, the slider 413 moves away from the first engaging assembly 3.

[0206] The following describes several key aspects of a child safety seat, taking into account its structure.

[0207] The first normal seating position is defined by the relative position of the turntable 12 and the base 11. The first engaging component 3 is in the second operating condition, and the locking component 5 is in the locked state.

[0208] The first elastic element 52 pulls the locking element 51 and the turntable 12 into a retracted state. The locking part 512 on the locking element 51 is located in the locking groove 111 of the base 11, and the turntable 12 and the base 11 cannot rotate relative to each other. In the second working condition, the first locking assembly 3 restricts the first hook 31, so that the first hook 31 cannot rotate and the locking handle 42 cannot move. The third elastic element 44 pulls the locking handle 42 and the turntable 12 into an extended state, and the second mark 412 of the marking element 41 is displayed in the window 13.

[0209] When the relative position between the turntable 12 and the base 11 is the first normal seating position, the locking component 5 is in the locked state, and the first engaging component 3 is switching from the second working state to the first working state:

[0210] As the first locking member 21 at the bottom of the basket 2 presses down on the first limiting member 32, the first limiting member 32 presses down on the fourth elastic member 33. Both first limiting members 32 and the first connecting member move downwards simultaneously, releasing the restriction on the first hook 31. The second locking member 22 at the bottom of the basket 2 presses down on the second limiting member 62, the second limiting member 62 presses down on the fifth elastic member 63. Both second limiting members 62 and the second connecting member move downwards simultaneously, releasing the restriction on the second hook 61. Under the pulling force of the third elastic member 44, the locking handle 42 moves away from the first locking assembly 3. The first hook 31 rotates and locks the first locking member 21. As the locking handle 42 moves away from the first locking assembly 3, the second hook 61 moves away from the first locking assembly 3 and locks with the second locking member 22. Therefore, the basket 2 is locked by the first locking assembly 3 and the second locking assembly 6, and the first locking assembly 3 and the second locking assembly 6 are in the first working condition. During this process, the latch handle 42 moves away from the first latch assembly 3 under the elastic force of the third elastic element 44, so the window 13 switches from the second mark 412 to the first mark 411.

[0211] The first normal seating position is when the turntable 12 and the base 11 are in relative positions, the first engaging component 3 is in the first working state, and the locking component 5 is in the locked state:

[0212] The first elastic element 52 pulls the locking element 51 and the turntable 12 into a retracted state. The locking part 512 on the locking element 51 is located in the locking groove 111 of the base 11, and the turntable 12 cannot rotate relative to the base 11. The third elastic element 44 pulls the locking handle 42 and the turntable 12 into a retracted state. The second elastic element 43 is pressed into the slide groove 421. The first mark 411 of the marking element 41 is displayed in the window 13.

[0213] When the turntable 12 and the base 11 are in the first normal seating position, the first engaging component 3 is in the first working state, and the locking component 5 is switching from the locked state to the unlocked state:

[0214] Applying force to knob 54 causes lever 53 to move locking member 51 against the force of first elastic member 52, moving it relative to base 11 towards the first engaging assembly 3. Locking part 512 disengages from locking groove 111 in base 11, allowing turntable 12 to rotate relative to base 11. During the movement of locking member 51 relative to base 11 towards the first engaging assembly 3, strip groove 511 pulls slider 413, pressing second elastic member 43 towards the first engaging assembly 3, thus switching the first mark 411 at window 13 to the second mark 412.

[0215] After the locking component 5 is unlocked, the turntable 12 can be rotated so that the turntable 12 rotates relative to the base 11. After the turntable 12 rotates 180 degrees relative to the base 11, the first engaging component 3 is located on the front side of the base 11 and the second engaging component 6 is located on the rear side of the base 11. At this time, the force on the knob 54 is released, and the locking component 51 moves away from the first engaging component 3 relative to the base 11 under the force of the first elastic component 52. The locking part 512 enters the locking groove 111 at the front of the base 11, and the locking component 51 locks the turntable 12 and the base 11. At the same time, the slider 413 moves away from the first engaging component 3 under the restoring force of the second elastic component 43 so that the second mark 412 at the window 13 is switched to the first mark 411.

[0216] In this utility model, the relationship between the extension direction of each component, hole or slot and the front-rear direction of the base 11 is defined with reference to the first normal seating position and the second normal seating position.
