Technical Field
[0001] The present invention relates to the technical field of child carriers, and in particular to a child safety seat and a base thereof capable of indicating whether the child safety seat is properly installed. Prior Art
[0002] Child safety seats have become a must-have item for children when traveling in a car. Child safety seats mainly include a base and a seat body that is clamped to the base. Child safety seats need to be used correctly to protect children. When in use, the base is connected to the car seat through the ISOFIX connector and the base is abutted against the backrest of the car seat, which can effectively prevent the child safety seat from tipping over, thereby ensuring the stability of the child safety seat connected to the car seat.
[0003] At present, most child safety seats do not have indicator devices. Whether the child safety seat is properly installed (for example, whether the base is in contact with the backrest of the car seat) depends on the subjective judgment of the operator, which may easily bring risks to the children in the seat due to human misjudgment. In addition, during the driving of the car, continuous bumps may easily cause the position of the child safety seat to shift, resulting in the base not being able to contact with the backrest of the car seat. If it is not checked and adjusted in time, the safety of the child safety seat will also be affected. Summary of the invention

In this embodiment, the base body 1 is provided with a guide groove 17, which extends in the front-to-back direction. The guide groove 17 accommodates the indicator 21 and guides the indicator 21 to slide in the front-to-back direction relative to the base body 1, and a limiting portion 171 is provided at the notch of the guide groove 17, and the limiting portion 171 prevents the indicator 21 from upwardly escaping from the guide groove 17. Specifically, the driving portion 212 is arranged in the guide groove 17 and is limited by the limiting portion 171 and the side wall of the guide groove 17, so that the driving portion 212 moves in a direction parallel to the extension direction of the guide groove 17, and the side wall of the guide groove 17 on one side of the second direction D2 extends along the first direction D1 The length of the side wall of the guide groove 17 on the other side of the second direction D2 extends along the first direction D1 is greater than the length of the side wall of the guide groove 17 on the other side of the second direction D2. The driving portion 212 (that is, the indicator 21) is guided to move along the first direction D1 by the side wall extending along the first direction D1 with a longer length.
[0054] The indicator 211 is partially exposed at the front end 11 or the side of the base body 1. In this embodiment, the indicator 211 is located at the front end 11 of the base 100 and is exposed at the front end 11 through the display window 31. The indicator 211 has a first indicator area 211a and a second indicator area 211b, and the first indicator area 211a and the second indicator area 211b selectively face the display window 31 to indicate that the base 100 is located at a correct installation position or an incorrect installation position. The first indicator area 211a and the second indicator area 211b can be marked with colors, words, symbols, shapes, etc., so as to distinguish the installation position of the child safety seat (i.e., the base 100). The correct installation position can correspond to the position where the base 100 of the child safety seat abuts against the backrest 310 of the car seat 300, and the incorrect installation position can correspond to the position where the base 100 of the child safety seat does not abut against the backrest 310 of the car seat 300. In this embodiment, the first indication area 211a is located behind the second indication area 211b in the first direction and is arranged adjacent to it. The first indication area 211a is marked in red, for example, and the second indication area 211b is marked in green, for example. The indication portion 211 has a first indication position and a second indication position. When the indication portion 211 is located in the first indication position, at least part of the first indication area 211a faces the display window 31, which is used to indicate that the child safety seat is in an incorrect installation position. When the indication portion 211 is located in the second indication position, only the second indication area 211b faces the display window 31, which is used to indicate that the child safety seat is in a correct installation position.
[0055] As shown in FIGS. 5 and 9 , the trigger 22 is disposed on the abutting portion 12. The trigger 22 comprises a driving connection portion 221, a pushing portion 222, and an intermediate portion 223 located between the driving connection portion 221 and the pushing portion 222. The intermediate portion 223 is pivotally connected to the abutting portion 12 of the base body 1 through a connecting pin 26, and the connecting pin 26 defines a pivot axis of the trigger 22. The driving connection portion 221 is accommodated in the receiving cavity 103 and is drivingly connected to the indicator 21. Specifically, the traction assembly 23 comprises a traction member 231, one end of which is connected to the driving connection portion 221, and the other end of which is connected to the driving portion 212 of the indicator 21.
[0056] In this embodiment, the trigger 22 can at least partially protrude from the base body 1, so as to allow the trigger 22 to be triggered by an external force and retracted toward the base body 1. The trigger 22 has a first position and a second position. When the base 100 is located at an incorrect installation position, the trigger 22 is located at the first position, and at least a portion of the push portion 222 extends out of the receiving cavity 103 through the through-hole 13 provided on the base 100 and protrudes from the base body 1, so as to allow the push portion 222 to be triggered by an external force and rotate. At this time, the indicator 21 is located at the first indicating position where at least a portion of the first indicating area 211a faces the display window 31. Specifically, at least a portion of the push portion 222 extends out of the receiving cavity 103 through the through-hole 13 provided on the abutting portion 12 and protrudes backward from the abutting portion 12, so as to allow the push portion 222 to be triggered by the backrest portion 310 of the car seat 300 and rotate. At this time, the abutting portion 12 and the backrest portion 310 are spaced apart, and the indicator 21 is located at the first indicating position. When the base 100 is in the correct installation position, the trigger 22 is in the second position, and at least a part of the push portion 222 is retracted to the receiving cavity 103 through the through-hole 13. At this time, the indicator 21 is in the second indication position where only the second indication area 211b faces the display window 31. Specifically, the push portion 222 is pushed by the backrest 310 of the car seat 300, and the push portion 222 is completely retracted to the receiving cavity 103 through the through-hole 13 provided on the abutment portion 12, and the abutment portion 12 is in contact with the backrest 310. At this time, the indicator 21 is in the second indication position. In other embodiments, when the base 100 is in the correct installation position, only at least a part of the push portion 222 may be retracted to the receiving cavity 103 through the through-hole 13 provided on the abutment portion 12. In the process of the trigger 22 rotating from the first position to the second position, the traction member 231 drives the indicator 21 to move from the first indication position to the second indication position.
[0057] As shown in FIG. 5 , FIG. 7 and FIG. 8 , the driving connection part 221 is connected to the base body 1 through a sliding pin 24.

The sliding pin 24 is simultaneously penetrated in the sliding groove 15 and the connecting groove 224. The driving connection part 221 rotates to drive the sliding pin 24 to slide in the sliding groove 15 and the connecting groove 224. The sliding pin 24 is connected to the driving part 212 of the indicating member 21 through a traction member 231. In this embodiment, the connecting groove 224 is a strip groove, and the sliding groove 15 is a strip groove. The extension direction of the sliding groove 15 is substantially linearly extended along the first direction D1, and the connecting groove 224 is also linearly extended, and the extension direction of the connecting groove 224 is substantially parallel to the extension direction of the trigger member 22. The extending direction of the connecting groove 224 forms an angle θ with the extending direction of the sliding groove 15, and the angle θ is an acute angle. In other embodiments, the angle θ may also be a right angle. In this way, when the trigger 22 rotates relative to the base body 1, the driving connection portion 221 of the trigger 22 is displaced relative to the sliding pin 24 along the extending direction of the connecting groove 224, and drives the sliding pin 24 to slide along the sliding groove 15 in the first direction D1. Through the coordinated use of the sliding groove 15 and the connecting groove 224, when the trigger 22 rotates, it can drive the sliding pin 24 to slide smoothly along the sliding groove 15, thereby driving the indicator 211 to move along the first direction. In other alternative embodiments, the connecting groove 224 may not be provided, and by connecting the sliding pin 24 with the driving connection portion 221 and setting the sliding groove 15 to a circular arc shape, when the trigger 22 rotates, it can drive the sliding pin 24 to slide smoothly along the sliding groove 15, thereby driving the indicator 21 to move through the traction member 231 connected to the sliding pin 24.

The two ends of the sheath 234 are respectively fixed on the base body 1, specifically, the two ends of the sheath 234 are respectively fixed on the first base shell 101 of the base body 1. The traction member 231 can move relative to the sheath 234. The sheath 234 can facilitate the arrangement of the traction member 231 along a predetermined direction.
[0061] In some embodiments, as shown in FIGS. 5 to 7 , the indicating mechanism 2 further includes a reset member 25, which is abutted between the indicating member 21 and the base body 1. When the indicating member 21 is located at the second indicating position, the reset member 25 drives the indicating member 21 to return to the first indicating position, thereby driving the triggering member 22 to move from the second position to the first position through the indicating member 21. The reset member 25 is, for example, a compression spring. Specifically, the first base shell 101 is provided with an abutting portion 16, and the abutting portion 16 is located in the receiving cavity 103. The indicating member 21 protrudes from the driving portion 212 toward the abutting portion 16 to form a positioning portion 214, and specifically, the positioning portion 214 is a protrusion extending from the side of the driving portion 212 substantially along the first direction D1. One end of the reset member 25 is sleeved outside the positioning portion 214 and abuts against the driving portion 212, and the other end of the reset member 25 abuts against the abutting portion 16 of the base 100. The traction member 231 passes through the positioning portion 214 to be connected to the second connection terminal 233.
[0062] As shown in FIG. 2 , FIG. 3 and FIG. 5 , according to the child safety seat and the base 100 thereof provided in the embodiment of the present application, the specific steps of installing the child safety seat and the base 100 thereof to the car seat 300 are as follows:
[0063] First, place the child safety seat (or base 100) on the seat portion 320 of the car seat, then pivot the support leg 4 forward toward the side away from the base body 1 and open it downward to abut against the foot pad of the car. Then pull the ISOFIX connector 5 backward toward the side away from the base body 1 and connect it to the connector configured on the car seat 300. At this time, push the base body 1 backward along the first direction D1, so that the base body 1 slides backward relative to the ISOFIX connector 5, so that the child safety seat (or base 100) moves from an incorrect installation position to a correct installation position. During this process, the triggering member 22 is pushed and triggered by the backrest portion 310 of the car seat 300 and rotates from the first position to the second position in the counterclockwise direction, and drives the sliding pin 24 to move backward along the first direction D1, thereby driving the indicating member 21 to move backward along the first direction D1 from the first indicating position (i.e., the position indicating that the base 100 is located in an incorrect installation position) to the second indicating position (i.e., the position indicating that the base 100 is located in the correct installation position). At this time, the abutting portion 12 just abuts against the backrest portion 310 of the car seat 300, that is, the child safety seat (or the base 100) is located in the correct installation position.
[0064] The specific steps of removing the child safety seat and its base 100 from the car seat 300 are as follows:
[0065] First, the base body 1 is pushed forward along the first direction D1 relative to the ISOFIX connector 5 to switch the child safety seat (or the base 100) from the correct installation position to the incorrect installation position. In this process, the trigger 22 is no longer abutted by the backrest portion 310 of the car seat 300, and the abutment portion 12 is spaced from the backrest portion 310, that is, the child safety seat (or the base 100) is in the incorrect installation position. The trigger 22 has a space protruding out of the outside of the base body 1, and the indicator 21 first moves forward from the second indication position along the first direction D1 to the first indication position under the elastic restoring force of the reset member 25, and drives the sliding pin 24 to move forward along the first direction D1 through the traction member 231, thereby driving the trigger 22 to rotate from the second position to the first position in the clockwise direction. At this time, the ISOFIX connector 5 is retracted to the base body 1, and the support foot 4 is folded to the bottom of the base body 1.
[0066] The child safety seat and the base 100 provided by the present invention can be switched between an incorrect installation position and a correct installation position because the triggering member 22 protrudes from the base body 1 and can be triggered by an external force to move, thereby driving the indicator 21 to move, and indicating whether the child safety seat and the base 100 are in the correct installation position or in the incorrect installation position through the position change of the indicator 21, so that the operator can easily determine whether the child safety seat and the base 100 are installed in place by checking the indicator 21, thereby avoiding the risk of the child safety seat tipping over due to the operator's subjective judgment error, thereby improving the safety of the child safety seat.
