Description

Technical Field

[0001] The present invention relates to the technical field of child carriers, and particularly to a child safety seat and its base that can indicate whether the child safety seat is properly installed. Background Art

[0002] Automobile child safety seats have become essential items for children during vehicle travel. A child safety seat mainly includes a base and a seat body that is snap-connected to the base. The child safety seat needs to be used correctly to play a role in protecting children. When in use, the base is connected to the vehicle seat through an ISOFIX connector and the backrest of the base abuts against the vehicle seat, so as to effectively prevent the child safety seat from tipping over and ensure the stability of the connection of the child safety seat.

[0003] Currently, most child safety seats do not have an indicating device. Whether the child safety seat is properly installed (for example, whether the base abuts against the backrest of the vehicle seat) needs to be subjectively judged by the operator, which is likely to bring risks to the children in the seat due to human misjudgment; in addition, during the driving of the vehicle, continuous bumps are likely to cause the position of the child safety seat to shift, and then cause the base not to abut against the backrest of the vehicle seat. If it cannot be checked and adjusted in time, it will also affect the safety of using the child safety seat. Summary of the Invention

[0004] Based on this, the present invention provides a child safety seat and its base that can conveniently and accurately judge whether the child safety seat (or the base) is correctly installed on the vehicle seat, improving the safety of using the child safety seat.

[0005] According to one aspect of the present invention, a base of a child safety seat is provided. The base includes: a base body and an indicating mechanism.

[0006] The indicating mechanism is disposed on the base body and includes an indicating member and a triggering member. The indicating member is movably disposed on the base body to indicate that the base is in a correct installation position or in an incorrect installation position. The triggering member is movably disposed on the base body, and at least a part of the triggering member protrudes from the base body to allow the triggering member to be touched by an external force and move. The triggering member is connected to the indicating member, and the movement of the triggering member drives the movement of the indicating member.

[0007] In one embodiment, when the base is in an incorrect installation position, at least a part of the triggering member protrudes from the base body to allow the triggering member to be touched by an external force and move; when the base is in a correct installation position, the triggering member is touched by an external force and retracts into the base body.

[0008] In one embodiment, the base body has an abutting portion for abutting against the backrest portion of the vehicle seat, and the actuating member is movably disposed on the abutting portion.

[0009] When the base is in an incorrect installation position, at least a part of the actuating member protrudes from the abutting portion to allow the actuating member to be actuated by an external force and move, and the abutting portion and the backrest portion are spaced apart.

[0010] When the base is in the correct installation position, the actuating member is pushed by the backrest portion and retracts into the base body, and the abutting portion abuts against the backrest portion.

[0011] In one embodiment, when the base is in the correct installation position, the actuating member is completely retracted into the base body.

[0012] In one embodiment, the actuating member has a driving connection portion, a pushing portion, and an intermediate portion located between the driving connection portion and the pushing portion. The driving connection portion is received in the base body and connected to the indicating member. The intermediate portion is pivotally connected to the base body, and the pushing portion protrudes from the base body to allow the actuating member to be actuated by an external force and rotate.

[0013] In one embodiment, the driving connection portion and the base body are respectively connected to a sliding pin. The sliding pin passes through the driving connection portion and the base body at the same time. The rotation of the driving connection portion drives the sliding pin to slide in the driving connection portion and the base body.

[0014] In one embodiment, the base body is provided with a sliding groove for the sliding pin to slide. The connecting groove extends in a straight line. The driving connection portion is provided with a connecting groove for the sliding pin to slide. The sliding groove extends in a straight line. The extending direction of the connecting groove forms an angle with the extending direction of the sliding groove, and the angle is set to be an acute angle or a right angle.

[0015] In one embodiment, the base body is provided with a sliding connection portion. The sliding connection portion has two side plate portions arranged oppositely. Both of the two side plate portions are provided with sliding grooves for the sliding pin to slide. The driving connection portion includes two ear plate portions arranged oppositely. The two ear plate portions are respectively provided with connecting grooves for the sliding pin to slide, and are respectively located on both sides of the sliding connection portion. The sliding pin is inserted into the two sliding grooves and the two connecting grooves.

[0016] In one embodiment, the sliding pin and the indicating member are respectively connected to a traction member. One end of the traction member connected to the sliding pin is movably disposed between the two side plate portions.

[0017] In one embodiment, the indicating member is provided with a clamping groove, and one end of the traction member connected to the indicating member is clamped in the clamping groove.

[0018] In one embodiment, the sliding pin is connected to the indicating member. The indicating member is slidably disposed on the base body. The sliding pin slides within the base body, driving the indicating member to slide relative to the base body.

[0019] In one embodiment, the base body is provided with a guiding groove for receiving the indicating member and guiding the indicating member to slide relative to the base body. A limiting portion is provided at the notch of the guiding groove to prevent the indicating member from disengaging from the guiding groove.

[0020] In one embodiment, the base further includes a support leg pivotally connected to the base body and an ISOFIX connector slidably connected to the base body. The portion where the base body is pivotally connected to the support leg is defined as the front end portion, the portion where the base body is slidably connected to the ISOFIX connector is defined as the rear end portion, and the portions on the left and right sides of the front end portion and the rear end portion of the base body are defined as the side portions. The indicating member is partially exposed at the front end portion or the side portion.

[0021] In one embodiment, the base further includes a display mechanism provided on the base body and having a display window. The indicating member has an indicating portion provided with a first indicating area and a second indicating area. The indicating member is movable between a first indicating position and a second indicating position.

[0022] When the indicating member is in the first indicating position, at least a part of the first indicating area faces the display window to indicate that the base is in an incorrect installation position; when the indicating member is in the second indicating position, only the second indicating area faces the display window to indicate that the base is in the correct installation position.

[0023] In one embodiment, the indicating mechanism further includes a traction assembly including a traction member and a sheath. One end of the traction member is connected to the indicating member, and the other end of the traction member is connected to a triggering member. The sheath is sleeved outside the traction member, and both ends of the sheath are fixed to the base body.

[0024] In one embodiment, the indicating mechanism further includes a reset member abutted between the indicating member and the base body. The reset member is adapted to drive the indicating member to reset, thereby driving the triggering member to return to at least partially protrude from the base body.

[0025] In one embodiment, the indicating member protrudes outward to form a positioning portion. One end of the reset member is sleeved outside the positioning portion and abuts against the indicating member, and the other end of the reset member abuts against the base body.

[0026] According to another aspect of the present invention, there is provided a child safety seat. The child safety seat includes a seat body and the base in any of the above embodiments. The seat body is mounted on the base.

[0027] In the process of switching between the incorrect installation position and the correct installation position of the above-mentioned child safety seat and its base, since the trigger member protrudes from the base body, it can be touched by an external force and move, thereby driving the indicator member to move, and indicating whether the child safety seat and its base are in the correct installation position or the incorrect installation position through the position change of the indicator member. This enables the operator to very conveniently determine whether the child safety seat and its base are properly installed by checking the indicator member, avoiding the risk of the child safety seat tipping over due to incorrect subjective judgment by the operator, and improving the safety of using the child safety seat.

[0057] The present invention provides a child safety seat and its base. Refer to Figure 1 , Figure 1 shows a perspective view of a child safety seat according to some embodiments of the present invention. The child safety seat provided according to some embodiments of the present invention includes a base 100 and a seat body 200 disposed on the base 100. The child safety seat and its base 100 will be described in detail below.

[0058] As Figures 1 to 3 shown, the base 100 of the child safety seat is adapted to be installed on a vehicle seat 300, and the seat body 200 is rotatably disposed on the base 100. The seat body 200 can be installed on the base 100 in the forward direction or in the reverse direction.

[0059] As Figures 1 to 3As shown, the base 100 includes a base body 1, a support leg 4 pivotally connected to the base body 1, and an ISOFIX connector 5 slidably connected to the base body 1. When the base 100 is installed on the vehicle seat 300, the support leg 4 supports on the vehicle floor mat, and the ISOFIX connector 5 is connected to the connector configured on the vehicle seat 300 to stably install the base 100 on the vehicle seat 300. Among them, the part where the base body 1 is pivotally connected to the support leg 4 is defined as the front end 11, the part where the base body 1 is slidably connected to the ISOFIX connector 5 is defined as the rear end, and the parts of the base 100 on the left and right sides of the front end 11 and the rear end are defined as the sides. And the direction where the front end 11 and the rear end are located is defined as the first direction D1 (i.e., the front-rear direction), and the left-right direction is defined as the second direction D2.

[0060] It should be noted that unless otherwise clearly specified and limited, the orientation terms such as "front", "rear", "left", "right", "up", and "down" of the child safety seat in each embodiment of the present invention are based on the "front", "rear", "left", "right", "up", and "down" orientations of the child carrier when the vehicle is driving normally. In the figure, the "left" and "right" directions are schematically shown by arrows L and R, and the "front" and "rear" directions are schematically shown by arrows F and B. These orientation terms are only used to make the description of the embodiments of the present invention clearer and are not used to improperly limit the protection scope of the present invention.

[0061] As Figures 2 to 5 shown, the base body 1 includes a first base housing 101 and a second base housing 102, and the first base housing 101 and the second base housing 102 together form a receiving cavity 103. A abutting portion 12 is provided at the rear end of the base body 1, and the abutting portion 12 is used to abut against the backrest portion 310 of the vehicle seat 300. Referring to Figure 2 and Figure 3 , when the base 100 (i.e., the child safety seat) is installed on the vehicle seat 300, the lower side surface of the first base housing 101 is placed stably on the seat portion 320 of the vehicle seat, the abutting portion 12 of the base 100 faces the backrest portion 310 of the vehicle seat 300, and abuts against the backrest portion 310 of the vehicle seat 300.

[0062] As Figures 2 to 3 shown, when the base 100 is installed on the vehicle seat 300, one end of the support leg 4 is pivotally connected to the front end 11, and the other end of the support leg 4 supports on the vehicle floor mat to stably install the child safety seat on the vehicle seat 300.

[0063] Continue to refer to Figure 2 and Figure 3, the base 100 is configured with two ISOFIX connectors 5, and the two ISOFIX connectors 5 are slidably arranged on the left and right sides of the base 100. The two ISOFIX connectors 5 are detachably connected to the connectors configured on the vehicle seat 300, so that the base 100 is detachably mounted on the vehicle seat 300. And the abutting portion 12 is located between the two ISOFIX connectors 5.

[0064] As Figures 5 to 6 shown, the base 100 further includes an indicating mechanism 2 and a display mechanism 3. The display mechanism 3 is arranged on the base body 1 and has a display window 31. Among them, the display window 31 is arranged at the front end portion 11. Specifically, an opening communicating with the accommodating cavity 103 is arranged on the upper side surface of the front end portion 11, and this opening forms the display window 31. The display mechanism 3 further includes a transparent member 32 arranged at the front end portion 11, and the transparent member 32 covers above the opening. Arranging the display mechanism 3 at the front end portion 11 of the base 100 is more convenient for the user to observe. Of course, the display mechanism 3 can also be arranged at other positions of the base 100, such as the side portion of the base 100, and this is not limited thereto.

[0065] In some embodiments, as Figures 5 to 8 shown, the indicating mechanism 2 is arranged on the base body 1. The indicating mechanism 2 includes an indicating member 21, a triggering member 22 and a traction assembly 23. Among them, the indicating member 21 is slidably arranged on the base body 1, and the triggering member 22 is rotatably arranged on the base body 1 and is drivingly connected to the indicating member 21 through the traction assembly 23. When the triggering member 22 is externally triggered to rotate, it can drive the indicating member 21 to slide relative to the base body 1 through the traction assembly 23, so as to indicate that the base 100 (or the child safety seat) is in the correct installation position or the incorrect installation position. In some other embodiments not shown, the traction assembly 23 may not be provided, but the triggering member 22 is directly connected to the indicating member 21, so that when the triggering member 22 is externally triggered to move, it can drive the indicating member 21 to move relative to the base body 1. This application does not make any restrictions on this.

[0066] Combined with Figure 10As shown, the indicating member 21 includes a main body portion 215, and a driving portion 212 and an indicating portion 211 provided at both ends of the main body portion 215. The driving portion 212 is connected to the traction assembly 23. The main body portion 215 extends substantially along the first direction D1, and the direction in which the indicating member 21 moves relative to the base body 1 is substantially parallel to the extending direction of the main body portion 215, that is, the indicating member 21 moves substantially in the front-rear direction. The main body portion 215 has a first straight section 2151 and a second straight section 2152 arranged in parallel with each other. The driving portion 212 is provided at one end of the first straight section 2151 away from the second straight section 2152, and the indicating portion 211 is provided at one end of the second straight section 2152 away from the first straight section 2151 and extends along a second direction D2 (i.e., the left-right direction) substantially perpendicular to the first direction D1. In this embodiment, the base body 1 is provided with a guiding groove 17. The guiding groove 17 extends in the front-rear direction. The guiding groove 17 houses the indicating member 21 and guides the indicating member 21 to slide relative to the base body 1 in the front-rear direction. And a limiting portion 171 is provided at the notch of the guiding groove 17. The limiting portion 171 blocks the indicating member 21 from disengaging upward from the guiding groove 17. Specifically, the driving portion 212 is inserted into the guiding groove 17 and is limited by the limiting portion 171 and the side wall of the guiding groove 17, so that the driving portion 212 moves in a direction parallel to the extending direction of the guiding groove 17. And the length of the side wall of the guiding groove 17 extending along the first direction D1 on one side of the second direction D2 is greater than the length of the side wall of the guiding groove 17 extending along the first direction D1 on the other side of the second direction D2. The driving portion 212 (i.e., the indicating member 21) is guided to move along the first direction D1 by the side wall with a longer length extending along the first direction D1.

[0067] Among them, the indicating portion 211 is partially exposed at the front end portion 11 or the side portion of the base body 1. In this embodiment, the indicating portion 211 is located at the front end portion 11 of the base 100 and is exposed at the front end portion 11 through the display window 31. The indicating portion 211 has a first indicating area 211a and a second indicating area 211b. The first indicating area 211a and the second indicating area 211b selectively face the display window 31 to indicate that the base 100 is in the correct installation position or in the incorrect installation position. The first indicating area 211a and the second indicating area 211b can be marked with, for example, colors, words, symbols, shapes, etc., so as to facilitate distinguishing 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 portion 310 of the vehicle 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 portion 310 of the vehicle seat 300. In this embodiment, the first indicating area 211a is located behind the second indicating area 211b in the first direction and is adjacent to each other. The first indicating area 211a is marked with red, for example, and the second indicating area 211b is marked with green, for example. The indicating portion 211 has a first indicating position and a second indicating position. When the indicating portion 211 is in the first indicating position, at least a part of the first indicating area 211a faces the display window 31, which is used to indicate that the child safety seat is in the incorrect installation position. When the indicating portion 211 is in the second indicating position, only the second indicating area 211b faces the display window 31, which is used to indicate that the child safety seat is in the correct installation position.

[0068] As Figure 5 and Figure 9 shown, the actuating member 22 is disposed on the abutting portion 12. The actuating member 22 has 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 the pivot axis of the actuating member 22. The driving connection portion 221 is received in the receiving cavity 103 and is drivingly connected to the indicating member 21. Specifically, the traction assembly 23 includes a traction member 231. One end of the traction member 231 is connected to the driving connection portion 221, and the other end of the traction member 231 is connected to the driving portion 212 of the indicating member 21.

[0069] In this embodiment, the actuating member 22 can at least partially protrude from the base body 1 to allow the actuating member 22 to be actuated by an external force and retract into the base body 1. The actuating member 22 has a first position and a second position. When the base 100 is in an incorrect installation position, the actuating member 22 is in the first position, and at least a part of the pushing 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 pushing portion 222 to be actuated by an external force and rotate. At this time, the indicating member 21 is in the first indicating position where at least a part of the first indicating area 211a faces the display window 31. Specifically, at least a part of the pushing 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 be pushed and actuated by the backrest portion 310 of the vehicle seat 300 to rotate. At this time, the abutting portion 12 and the backrest portion 310 are spaced apart, and the indicating member 21 is in the first indicating position. When the base 100 is in the correct installation position, the actuating member 22 is in the second position, and at least a part of the pushing portion 222 retracts into the receiving cavity 103 through the through hole 13. At this time, the indicating member 21 is in the second indicating position where only the second indicating area 211b faces the display window 31. Specifically, the pushing portion 222 is pushed by the backrest portion 310 of the vehicle seat 300, and the pushing portion 222 completely retracts into the receiving cavity 103 through the through hole 13 provided on the abutting portion 12, and the abutting portion 12 abuts against the backrest portion 310. At this time, the indicating member 21 is in the second indicating position. In other embodiments, when the base 100 is in the correct installation position, only at least a part of the pushing portion 222 may retract into the receiving cavity 103 through the through hole 13 provided on the abutting portion 12. During the rotation of the actuating member 22 from the first position to the second position, the traction member 231 drives the indicating member 21 to move from the first indicating position to the second indicating position.

[0070] Such as Figure 5 , Figure 7 and Figure 8As shown, the driving connection part 221 is connected to the base body 1 through a sliding pin 24. Among them, a sliding connection part 14 is arranged in the accommodation cavity 103, and the sliding connection part 14 is arranged on the first base shell 101. A sliding groove 15 for the sliding pin 24 to slide is arranged on the sliding connection part 14 of the base body 1, and a connection groove 224 for the sliding pin 24 to slide is arranged on the driving connection part 221. The sliding pin 24 is simultaneously inserted into the sliding groove 15 and the connection groove 224. When the driving connection part 221 rotates, it drives the sliding pin 24 to slide in the sliding groove 15 and the connection groove 224. The sliding pin 24 is connected to the driving part 212 of the indicating part 21 through a traction part 231. In this embodiment, the connection groove 224 is a strip-shaped groove, and the sliding groove 15 is a strip-shaped groove. The extending direction of the sliding groove 15 extends linearly along the first direction D1, and the connection groove 224 also extends linearly, and the extending direction of the connection groove 224 is substantially parallel to the extending direction of the trigger part 22. The extending direction of the connection groove 224 forms an angle θ with the extending direction of the sliding groove 15, and this angle θ is an acute angle. In other embodiments, this angle θ can also be a right angle. With such a setting, when the trigger part 22 rotates relative to the base body 1, the driving connection part 221 of the trigger part 22 displaces relative to the sliding pin 24 along the extending direction of the connection groove 224, and drives the sliding pin 24 to slide along the sliding groove 15 in the first direction D1. Through the combined use of the sliding groove 15 and the connection groove 224, when the trigger part 22 rotates, it can drive the sliding pin 24 to slide smoothly along the sliding groove 15, so as to drive the indicating part 211 to move in the first direction. In other alternative embodiments, the connection groove 224 may not be provided. By connecting the sliding pin 24 to the driving connection part 221 and setting the sliding groove 15 to be arc-shaped, when the trigger part 22 rotates, it can drive the sliding pin 24 to slide smoothly along the sliding groove 15, so as to drive the indicating part 21 to move through the traction part 231 connected to the sliding pin 24.

[0071] Referring to Figures 7 to 9 , the sliding connection part 14 has two side plate parts 142 arranged oppositely, and sliding grooves 15 are arranged on both side plate parts 142. The driving connection part 221 includes two ear plate parts 2211 arranged oppositely. Connection grooves 224 are respectively arranged on the two ear plate parts 2211, and are respectively located on both sides of the sliding connection part 14. The sliding pin 24 is inserted into the two sliding grooves 15 and the two connection grooves 224. First connection terminals 232 and second connection terminals 233 are respectively arranged at both ends of the traction part 231. The traction part 231 is connected to the sliding pin 24 through the first connection terminal 232, and the first connection terminal 232 is movably arranged between the two side plate parts 142 and between the two ear plate parts 2211.

[0072] As Figure 5 and Figure 7As shown in the figure, a receiving cavity 141 is provided in the sliding connection portion 14, and two side plate portions 142 respectively form two side walls of the receiving space 141, and the sliding groove 15 communicates with the receiving cavity 141. The first connection terminal 232 is movably disposed in the receiving cavity 141, and the sliding pin 24 is inserted into the first connection terminal 232. The traction member 231 passes through the side wall of the receiving cavity 141 and is connected to the indicating member 21. The moving direction of the first connection terminal 232 is substantially parallel to the extending direction of the sliding groove 15. The second connection terminal 233 is connected to the indicating member 21. The driving portion 212 is provided with a clamping groove 213, and the second connection terminal 233 is clamped in the clamping groove 213. The traction member 231 passes through the side wall of the clamping groove 213 and is connected to the actuating member 22 through the second connection terminal 233 and the sliding pin 24. The traction member 231 is, for example, a steel wire rope, a carbon fiber rope, etc. When the triggering member 22 drives the sliding pin 24 to slide along the sliding groove 15, the first connection terminal 232 is driven to move along the first direction D1, so that the second connection terminal 233 is driven to move along the first direction D1 through the traction member 231, and the second connection terminal 233 drives the indicating member 21 to move along the first direction D1.

[0073] As Figures 5 to 8 shown, the traction assembly 23 is disposed in the receiving cavity 103. The traction assembly 23 further includes a sheath 234 sleeved outside the traction member 231. Both ends of the sheath 234 are respectively fixed on the base body 1. Specifically, both ends of the sheath 234 are respectively fixed on the first base housing 101 of the base body 1. The traction member 231 can move relative to the sheath 234. The sheath 234 can facilitate arranging the traction member 231 along a predetermined direction.

[0074] In some embodiments, as Figures 5 to 7 shown, the indicating mechanism 2 further includes a reset member 25, and the reset member 25 abuts 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, so as to drive the actuating 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 housing 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. Specifically, the positioning portion 214 is a protrusion extending substantially along the first direction D1 from the side surface of the driving portion 212. 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 penetrates through the side wall of the positioning portion 214 to be connected to the second connection terminal 233.

[0075] As Figure 2 , Figure 3 and Figure 5As shown, for the child safety seat and its base 100 provided by the embodiments of the present application, the specific steps for installing the child safety seat and its base 100 to the vehicle seat 300 are as follows:

[0076] First, place the child safety seat (or the base 100) on the seat portion 320 of the vehicle seat, then pivot the support leg 4 forward away from the base body 1 and downward to abut against the vehicle floor mat. Then, pull the ISOFIX connector 5 backward away from the base body 1 and connect it to the connector provided on the vehicle 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 the base 100) moves from an incorrect installation position to a correct installation position. During this process, the actuating member 22 is pushed and actuated by the backrest portion 310 of the vehicle seat 300 and rotates counterclockwise from the first position to the second position, 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 in an incorrect installation position) to the second indicating position (i.e., the position indicating that the base 100 is in a correct installation position). At this time, the abutting portion 12 just abuts against the backrest portion 310 of the vehicle seat 300, that is, the child safety seat (or the base 100) is in the correct installation position.

[0077] The specific steps for detaching the child safety seat and its base 100 from the vehicle seat 300 are as follows:

[0078] First, push the base body 1 forward along the first direction D1 relative to the ISOFIX, so that the child safety seat (or the base 100) switches from the correct installation position to the incorrect installation position. During this process, since the actuating member 22 is no longer abutted by the backrest portion 310 of the vehicle seat 300, the actuating member 22 has a space protruding outside the base body 1, and the indicating member 21 first moves forward along the first direction D1 from the second indicating position to the first indicating position under the elastic restoring force of the restoring member 25, and drives the sliding pin 24 to move forward along the first direction D1 through the traction member 231, thereby driving the actuating member 22 to rotate clockwise from the second position to the first position. At this time, the abutting 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, and then the ISOFIX connector 5 is retracted into the base body 1, and the support leg 4 is folded to the bottom of the base body 1.

[0079] The child safety seat and its base 100 provided by the present invention, during the process of switching between an incorrect installation position and a correct installation position, since the trigger member 22 protrudes from the base body 1 and can be touched by an external force to move, thereby driving the indicator member 21 to move, and the position change of the indicator member 21 is used to indicate whether the child safety seat and its base 100 are in the correct installation position or in an incorrect installation position, so that the operator can very conveniently judge whether the child safety seat and its base 100 are installed in place by checking the indicator member 21, avoiding the risk of the child safety seat tipping over due to the operator's subjective judgment error, and improving the safety of using the child safety seat.
