[0084] As Figure 1 shown, an embodiment of the present invention provides a child carrier, which can be, for example, a car safety seat, a baby carrier basket or a baby stroller, etc. The child carrier includes a carrier body 10 and a seat belt assembly 20 mounted on the carrier body 10. The seat belt assembly 20 and the child carrier can remind the caregiver of the tightened state of the seat belt assembly 20, so as to avoid the situation that the seat belt is not tightened or over-tightened. Hereinafter, taking the child carrier as a car safety seat as an example, the structure of the child carrier will be described in detail.

[0085] As Figure 1 shown, the carrier body 10 may include a carrier base 11 and a seat body 12. The carrier base 11 is used for being fixedly mounted on an automobile seat, and the seat body 12 is mounted on the carrier base 11 in a detachable or non-detachable manner. The seat body 12 includes a seat portion 12a and a backrest portion 12b which are connected to each other. A seating space 12c for accommodating a child is formed between the seat portion 12a and the backrest portion 12b. The seat belt assembly 20 is mounted on the seat body 12.

[0086] Specifically, as Figures 1 to 3 shown, the seat belt assembly 20 includes a seat belt body 100, a driving mechanism 200 and a reminding mechanism 300. The seat belt body 100 is used for restraining a child on the carrier body 10 and can be switched between a tightened state and a relaxed state. The driving mechanism 200 is drivingly connected to the seat belt body 100. The reminding mechanism 300 is connected to the driving mechanism 200. Among them, when the seat belt body 100 is in a tightened state, it drives the driving mechanism 200 to drive the reminding mechanism 300 to act so that the reminding mechanism 300 generates a reminding signal.

[0087] In this embodiment, as Figure 1As shown, the seat belt body 100 may include a shoulder belt set 110, a crotch belt set 120, a waist belt set 130, and an adjustment belt 140. Each of the shoulder belt set 110, the crotch belt set 120, and the waist belt set 130 includes a corresponding connecting belt and a connecting buckle. That is, the shoulder belt set 110 includes a shoulder belt body 111 and a shoulder belt buckle 112, the crotch belt set 120 includes a crotch belt body 121 and a crotch belt buckle (not shown in the drawings), and the waist belt set 130 includes a waist belt body 131 and a waist belt buckle 132. There are two sets of the shoulder belt set 110 and the waist belt set 130 respectively, and they are spaced apart and arranged on the left and right sides of the seat body 12. The two shoulder belt sets 110 are used to restrain the shoulders of the child, and the two waist belt sets 130 are used to restrain the waist of the child. In this embodiment, the shoulder belt body 111 of each shoulder belt set 110 is directly connected to the waist belt body 131 of the corresponding side waist belt set 130, and the shoulder belt buckle 112 of each shoulder belt set 110 and the waist belt buckle 132 of the corresponding side waist belt set 130 are actually the same component. The shoulder belt buckle 112 (or the waist belt buckle 132) is sleeved at the junction of the shoulder belt body 111 and the waist belt body 131 to distinguish the shoulder belt body 111 and the waist belt body 131. Among them, one end of the shoulder belt body 111 away from the shoulder belt buckle 112 (or the waist belt buckle 132) extends to the back of the backrest portion 12b through the first through hole 12b1 on the backrest portion 12b, and one end of the waist belt body 131 away from the shoulder belt buckle 112 (or the waist belt buckle 132) is fixed to the back of the seat portion 12a through the second through hole 12a1 on the seat portion 12a. In other embodiments, the shoulder belt body 111 and the waist belt body 131 of the corresponding side may also be connected through corresponding fasteners. The two shoulder belt buckles 112 (or the waist belt buckles 132) can be detachably buckled with the crotch belt buckle. One end of the crotch belt set 120 away from the two shoulder belt buckles 112 (or the waist belt buckles 132) is connected to the driving mechanism 200. The crotch belt set 120 is used to restrain the crotch of the child. One end of the adjustment belt 140 is fixed to the front end of the seat portion 12a through the length adjustment mechanism 150 and is located in front of the driving mechanism 200. The other end of the adjustment belt 140 bypasses the bottom surface of the seat portion 12a and extends to the back of the backrest portion 12b to be connected to one end of the two shoulder belt bodies 111 away from the shoulder belt buckle 112 (or the waist belt buckle 132). In this embodiment, the length adjustment mechanism 150 can be switched between a locked state and an unlocked state. When the length adjustment mechanism 150 is in the unlocked state, the length of the adjustment belt 140 can be either lengthened or shortened. When the length adjustment mechanism 150 is in the locked state, the length of the adjustment belt 140 can only be lengthened.

[0088] It should be noted that the azimuth terms related to front, back, left, and right mentioned in the context of this application are based on Figure 1 the orientation of the car safety seat shown in the figure. Specifically, the direction the child faces after sitting in the car safety seat can be regarded as the front, the direction the child turns his back to can be regarded as the back, the left side when the reader faces the car safety seat can be regarded as the left side, and the right side when the reader faces the car safety seat can be regarded as the right side.

[0089] Optionally, the drive mechanism 200 and the corresponding reminder mechanism 300 can have various forms. For example, in the first embodiment, as Figures 4 to 7 shown, the drive mechanism 200 can include a pushing member 210, a rotating seat 220, a mounting bracket 230, and a third restoring member 240, and the reminder mechanism 300 can include a mounting seat 310, a pushing sleeve 320, a pin 330, a push rod 340, a first restoring member 351, and a second restoring member 352. The seat belt assembly 20 including the drive mechanism 200 and the reminder mechanism 300 in this embodiment is disposed on the crotch belt group 120.

[0090] Specifically, as Figure 4 and Figure 5 shown, the rotating seat 220 is rotatably disposed on the vehicle body 10. The rotating seat 220 includes a rotating disk 221 that is generally cylindrical and a connecting rod 222 fixed to the outer peripheral edge of the rotating disk 221. One end of the connecting rod 222 away from the rotating disk 221 is connected to one end of the crotch belt body 121 away from the crotch belt buckle. In this embodiment, the crotch belt body 121 is made of a plastic material, and the crotch belt body 121 is connected to the connecting rod 222 by two fasteners 102 such as screws.

[0091] As Figure 6 and Figure 7 shown, the pushing member 210 protrudes from the outer peripheral edge of the rotating seat 220 and is spaced apart from the connecting rod 222. The rotating seat 220 is rotatable between a first rotational position and a second rotational position. When the seat belt body 100 is in a tightened state (that is, the seat belt body 100 is in a just tightened state, at this time the seat belt body 100 can play a safety protection role and will not strangle the child to cause discomfort), as Figure 7 shown, the rotating seat 220 is in the first rotational position, and the pushing member 210 presses the reminder mechanism 300 to cause the reminder mechanism 300 to generate a reminder signal; when the seat belt body 100 is in a relaxed state, as Figure 6 shown, the rotating seat 220 is in the second rotational position, and the pushing member 210 is spaced apart from the reminder mechanism 300. In this embodiment, as Figures 1 to 3 shown, the seat belt body 100 being in a tightened state specifically means that after the child sits on the seat body 12, after buckling the shoulder belt buckle 112 and the crotch belt buckle, the adjustment belt 140 is pulled through the length adjustment mechanism 150, so that the adjustment belt 140 pulls the crotch belt body 121 to rotate through the shoulder belt body 111. The crotch belt body 121 drives the rotating seat 220 to rotate, so that the rotating seat 220 rotates from the second rotational position as Figure 6 shown to the first rotational position as Figure 7 shown, thereby causing the pushing member 210 to press the reminder mechanism 300 to cause the reminder mechanism 300 to generate a reminder signal.

[0092] Specifically, as Figures 6 to 8 shown, the mounting bracket 230 of the driving mechanism 200 includes a first mounting plate 231 and a second mounting plate 232 which are oppositely arranged, and a connecting plate 233 connected between the first mounting plate 231 and the second mounting plate 232. The connecting plate 233 is fixedly arranged on the vehicle body 10, and the rotating disc 221 is pivotally connected between the first mounting plate 231 and the second mounting plate 232 through a pivot shaft 101 passing through its central axis. In this embodiment, the third restoring member 240 is a torsion spring, including a sleeving cylinder 241 and a first abutting end 242 and a second abutting end 243 extending from the sleeving cylinder 241. The sleeving cylinder 241 of the third restoring member 240 is sleeved on the pivot shaft 101, and the first abutting end 242 and the second abutting end 243 respectively abut against the rotating disc 221 and the mounting bracket 230, and the third restoring member 240 always moves the rotating seat 220 towards the second rotating position. Thus, when the shoulder strap buckle 112 and the crotch strap buckle are unfastened, the rotating seat 220 can automatically turn to the second rotating position under the elastic restoring force of the second restoring member 352, so as to facilitate taking the child out of the seat body 12.

[0093] Specifically, as Figure 8 shown, the mounting seat 310 of the reminding mechanism 300 includes a fixing plate 311, a mounting body 312 fixedly arranged on one side of the fixing plate 311, and a plurality of fixing columns 313. In this embodiment, please refer to Figures 9 to 11 together, there is an installation groove 12a2 penetrating through the seat part 12a and a plurality of through holes 12a3 arranged around the seat part 12a on the seat part 12a of the vehicle body 10. The fixing plate 311 has an indicating window 3111 and the plurality of fixing columns 313 are arranged around the indicating window 3111. The mounting seat 310 is arranged on the top surface of the seat part 12a, that is, the side of the seat part 12a facing the riding space 12c, and the indicating window 3111 is opposite to the installation groove 12a2, and the plurality of fixing columns 313 are opposite to the plurality of through holes 12a3. Among them, each fixing column 313 is provided with a fixing hole 3131 opposite to and communicating with the corresponding through hole 12a3. The connecting plate 233 of the mounting bracket 230 of the driving mechanism 200 is arranged on the bottom surface of the seat part 12a, that is, the side of the seat part 12a facing away from the riding space 12c, and both the first connecting plate 233 and the second connecting plate 233 extend into the installation groove 12a2. The connecting plate 233 is provided with a plurality of through holes 2331 which respectively correspond to the plurality of through holes 12a3 on the seat part 12a one by one. A plurality of fasteners 102 such as screws respectively pass through the plurality of through holes 2331 on the connecting plate 233, the plurality of through holes 12a3 on the seat part 12a and the plurality of fixing holes 3131 on the plurality of fixing columns 313 to respectively fix the mounting seat 310 and the mounting bracket 230 on the seat part 12a (i.e., the vehicle body 10).

[0094] As Figures 10 to 11As shown, the installation body 312 is generally located on the front side of the indication window 3111, and the installation body 312 is generally in a cuboid structure. A first accommodation groove 3121 is provided on one side of the installation body 312 close to the indication window 3111. Limiting grooves 3122 communicating with the first accommodation groove 3121 are respectively provided on the left and right sides of the installation body 312. In this embodiment, as Figure 8 and Figure 10 shown, the limiting grooves 3122 on the left and right sides of the installation body 312 are both L-shaped grooves, and the limiting groove 3122 on the right side of the installation body 312 and the limiting groove 3122 on the left side of the installation body 312 are axisymmetric figures. Hereinafter, taking Figure 8 the limiting groove 3122 on the right side of the installation body 312 in as an example to specifically describe its structure: The L-shaped limiting groove 3122 includes a first groove portion 3122a and a second groove portion 3122b that communicate with each other and are substantially perpendicular. The second groove portion 3122b is located above the first groove portion 3122a, the second groove portion 3122b extends substantially in the horizontal direction, and the first groove portion 3122a extends substantially in the vertical direction. The groove wall at the end of the first groove portion 3122a away from the second groove portion 3122b, that is, the bottom groove wall of the first groove portion 3122a is the first groove wall 3122c. The groove wall at the end of the second groove portion 3122b away from the first groove portion 3122a, that is, the front groove wall of the first groove portion 3122a is the second groove wall 3122d.

[0095] As Figures 6 to 8 shown, the push sleeve 320 of the reminder mechanism 300 is movably disposed in the first accommodation groove 3121. The push sleeve 320 is generally in a cuboid structure. On the side of the push sleeve 320 facing away from the notch of the first accommodation groove 3121, that is, on the front side of the push sleeve 320, a second accommodation groove 322 is provided, and the extending direction of the second accommodation groove 322 is substantially arranged along the front-rear direction of the vehicle body 10. Driving grooves 321 communicating with the second accommodation groove 322 are respectively provided on the left and right sides of the push sleeve 320. In this embodiment, both of the two driving grooves 321 are inclined grooves that can communicate with the corresponding limiting grooves 3122. There is also such a relationship between each driving groove 321 and the corresponding limiting groove 3122 on its side: that is, the extending direction of the first groove portion 3122a of the limiting groove 3122 and the extending direction of the driving groove 321 are staggered with each other, and the extending direction of the second groove portion 3122b of the limiting groove 3122 is also staggered with the extending direction of the driving groove 321.

[0096] As Figure 4 、 Figure 5 and Figure 8As shown, the push rod 340 of the reminder mechanism 300 is rotatably and movably disposed within the push sleeve 320. The push rod 340 is generally in a cylindrical structure, and the central axis direction of the push rod 340 is generally arranged along the front-rear direction of the vehicle body 10. Two latch pins 330 are respectively and spacedly disposed on the side wall of the push rod 340, and the two latch pins 330 are arranged along the same radial direction of the push rod 340. In other embodiments, only one latch pin 330 may be provided, and the latch pin 330 penetrates through the side wall of the push rod 340 along a certain radial direction of the push rod 340. Each latch pin 330 sequentially passes through the driving groove 321 and the limiting groove 3122 and is movable between a first position and a second position. When the latch pin 330 is in the first position, it abuts against the first groove wall 3122c, and when the latch pin 330 is in the second position, it abuts against the second groove wall 3122d. Thus, when the seat belt body 100 is in a tightened state, the crotch belt body 121 drives the rotating seat 220 to rotate to the first rotation position, so that the pushing member 210 provided on the rotating seat 220 pushes the push sleeve 320 along the first direction D1, so that the latch pin 330 moves from the first position to the second position, and when the latch pin 330 moves to the second position, it impacts the second groove wall 3122d to generate a reminder sound.

[0097] As Figures 6 to 8 shown, the first reset member 351 may be a spring, and the first reset member 351 constantly pushes the push sleeve 320 in the opposite direction of the first direction D1. Specifically, the two ends of the first reset member 351 respectively abut against the mounting seat 310 and the push sleeve 320. In this embodiment, the front end of the first reset member 351 abuts against the bottom of the first receiving groove 3121, and the rear end of the second reset member 352 abuts against the front end of the push sleeve 320. Thus, the first reset member 351 constantly makes the push sleeve 320 have a tendency to move in the opposite direction of the first direction D1. The second reset member 352 may also be a spring, and the second reset member 352 constantly pushes the push rod 340 in the first direction D1. Specifically, the two ends of the second reset member 352 respectively abut against the push rod 340 and the push sleeve 320. In this embodiment, a sleeve column 341 is provided on the side of the push rod 340 facing the bottom of the second receiving groove 322. The front end of the second reset member 352 is sleeved on the sleeve column 341 and abuts against the push rod 340, and the rear end of the second reset member 352 abuts against the bottom of the second receiving groove 322. Thus, the second reset member 352 constantly makes the push rod 340 have a tendency to move in the first direction D1.

[0098] Thus, when the shoulder belt buckle 112 and the crotch belt buckle are buckled, the adjustment belt 140 is tightened by the length adjustment mechanism 150, so that the adjustment belt 140 pulls the crotch belt body 121 to rotate through the shoulder belt body 111. After the crotch belt body 121 drives the rotating seat 220 to rotate to the first rotation position, as Figures 6 to 7As shown, the pushing member 210 provided on the rotating seat 220 rotates along the third direction D3 until it abuts against the pushing sleeve 320 to move it along the first direction D1, and the first restoring member 351 undergoes elastic deformation. At the same time, as Figures 4 to 5 shown, the pushing sleeve 320 drives the pushing rod 340 to rotate through the cooperation of the driving groove 321 and the latch 330, and at the same time makes the pushing rod 340 move in the opposite direction of the first direction D1 relative to the pushing sleeve 320, and the second restoring member 352 undergoes elastic deformation. Taking the latch 330 provided on the right side of the pushing rod 340 as an example, the latch 330 moves upward under the limiting action of the driving groove 321, that is, in the fourth direction D4, so that the latch 330 originally abutted against the first groove wall 3122c in the first position moves along the fourth direction D4 to disengage from the first groove portion 3122a and enter the second groove portion 3122b. Since the first groove portion 3122a extends horizontally forward, the latch 330 that loses the side wall limiting action of the first groove wall 3122c then moves along the first direction D1 under the elastic force of the second restoring member 352 and collides with the second groove wall 3122d to generate a reminder signal similar to a "click" sound, thereby reminding the parent that the seat belt body 100 has been tightened in place.

[0099] When the shoulder belt buckle 112 and the hip belt buckle are disengaged, or after the adjustment belt 140 is adjusted to make the shoulder belt body 111 stretched and loose, as Figures 7 to 6 shown, the rotating seat 220 will be reset to the second rotating position under the action of the third restoring member 240, so that the pushing member 210 provided on the rotating seat 220 rotates in the opposite direction of the third direction D3 to disengage from the pressing on the pushing sleeve 320, that is, the pushing member 210 and the pushing sleeve 320 are spaced apart. In this way, the pushing sleeve 320 is reset in the opposite direction of the first direction D1 under the elastic force of the first restoring member 351. The pushing sleeve 320 drives the pushing rod 340 to rotate through the cooperation of the driving groove 321 and the latch 330, and at the same time makes the pushing rod 340 move in the first direction D1 relative to the pushing sleeve 320. Taking the latch 330 provided on the right side of the pushing rod 340 as an example, as Figures 5 to 4 shown, the latch 330 moves obliquely downward under the limiting action of the driving groove 321, that is, in the opposite direction of the fourth direction D4. Since the pushing sleeve 320 moves in the opposite direction of the first direction D1 relative to the mounting seat 310, the latch 330 also moves in the opposite direction of the first direction D1 relative to the mounting seat 310 to disengage from the second groove portion 3122b and enter the first groove portion 3122a, and finally abuts against the first groove wall 3122c.

[0100] Furthermore, as Figure 2 and Figure 3As shown, the reminder mechanism 300 in this embodiment may further include a first indicating member 361 and a second indicating member 362. Both the first indicating member 361 and the second indicating member 362 are disposed on the rotating seat 220 and rotate with the rotating seat 220. Specifically, the first indicating member 361 and the second indicating member 362 may be indicating blocks of different colors or different patterns respectively transfer-printed on the side wall of the rotating disk 221 of the rotating seat 220. For example, the first indicating member 361 may be a green indicating block, and the second indicating member 362 may be a red indicating block. When the rotating seat 220 is in the first rotating position, the first indicating member 361 is opposite to the indicating window 3111 on the mounting seat 310. When the rotating seat 220 is in the second rotating position, the second indicating member 362 is opposite to the indicating window 3111 on the mounting seat 310. In this way, it can further play a role in reminding the caregiver whether the seat belt body 100 has been tightened in place.

[0101] In the second embodiment, the driving mechanism 200 may also only include the rotating seat 220 in the above first embodiment, and the reminder mechanism 300 may also only include the mounting seat 310, the first indicating member 361 and the second indicating member 362 in the above first embodiment. When the seat belt body 100 is in a tightened state, the rotating seat 220 is in the first rotating position, and the first indicating member 361 is opposite to the indicating window 3111 to serve as a reminder signal that the seat belt body 100 has been tightened in place. When the seat belt body 100 is in a relaxed state, the rotating seat 220 is in the second rotating position, and the second indicating member 362 is opposite to the indicating window 3111 to serve as a reminder signal that the seat belt body 100 has not been tightened in place.

[0102] In the third embodiment, as Figures 13 to 15 shown, the driving mechanism 200 may include a pushing member 210 and a fourth reset assembly 250, and the reminder mechanism 300 may include a limiting sleeve 370 and a pushing member 380. The seat belt assembly 20 including the driving mechanism 200 and the reminder mechanism 300 in this embodiment may be disposed on the shoulder belt group 110, the crotch belt group 120 or the waist belt group 130. The following takes the seat belt assembly 20 including the driving mechanism 200 and the reminder mechanism 300 in this embodiment being disposed on one of the waist belt groups 130 as an example for specific description:

[0103] The waist belt group 130 includes a waist belt body 131 (which may also be other connecting belts, such as the shoulder belt body 111 if used in the shoulder belt group 110 or the crotch belt body 121 if used in the crotch belt group 120) and a fixed buckle 133 (as Figure 13 and Figure 14 shown). In this embodiment, the fixed buckle 133 is a D-ring and is movably disposed on the bottom surface of the seat portion 12a. One end of the waist belt body 131 away from the shoulder belt body 111 is wound and fixed on the fixed buckle 133. As Figure 15 and Figure 18As shown, the pushing member 210 is generally in a cylindrical structure and protrudes from one side of the fixing buckle 133 facing the seat portion 12a. A limiting post 1331 is also provided on the side of the fixing buckle 133 facing the seat portion 12a. The limiting post 1331 and the pushing member 210 are respectively arranged at both ends of the fixing buckle 133 at intervals.

[0104] Further, as Figure 16 , Figure 17 and Figure 19 shown, the limiting sleeve 370 is fixedly arranged on the bottom surface of the seat portion 12a. The limiting sleeve 370 is generally in a cylindrical structure. A through third receiving groove 373 is provided in the limiting sleeve 370. Two oppositely arranged guiding holes 374 communicating with the third receiving groove 373 are provided on the side wall of the limiting sleeve 370. The extending direction of the guiding holes 374 is parallel to the axial direction of the limiting sleeve 370. Two oppositely arranged pushing inclined surfaces 371 and two oppositely arranged impact portions 372 are provided on the inner wall of the guiding holes 374. Among them, each pushing inclined surface 371 is generally located between the corresponding guiding hole 374 and the impact portion 372 on that side.

[0105] Further, as Figure 16 , Figure 17 and Figure 20 shown, the pushing member 380 is movably arranged in the limiting sleeve 370. The pushing member 380 includes a pushing base 381, an elastic rib 382 and a guiding member 383 arranged on one surface of the pushing base 381. Specifically, the elastic rib 382 includes an elastic body 3821 and a pushing convex 3822 connected to each other. The elastic body 3821 is generally in a rectangular sheet structure and is connected to the pushing base 381 at one end. There are two pushing convexes 3822 protruding from both sides of the end of the elastic body 3821 away from the pushing base 381. There are two guiding members 383 respectively arranged on both sides of the elastic body 3821. The pushing member 380 is installed in the third receiving groove 373 of the limiting sleeve 370. The two guiding members 383 are respectively at least partially inserted into the two guiding holes 374 and can slide along the two guiding holes 374 respectively, so as to limit the sliding stroke of the pushing member 380 in the limiting sleeve 370, and at the same time, the pushing member 380 can always move along the axial direction of the limiting sleeve 370.

[0106] Further, as Figure 16 and Figure 17As shown, the pushing member 380 is movable between a third position and a fourth position. The pushing inclined surface 371 has a first end 3711 close to the guiding hole 374 and a second end 3712 far from the guiding hole 374. The inclination direction of the pushing inclined surface 371 intersects with the extending direction of the guiding hole 374. When the pushing member 380 is in the third position, the elastic rib 382 abuts against the pushing inclined surface 371. When the pushing member 380 is in the fourth position, the elastic rib 382 passes over the second end 3712 of the pushing inclined surface 371 and is located on the side of the second end 3712 far from the first end 3711, that is, the elastic rib 382 no longer abuts against the pushing inclined surface 371. When the belt body 131 (or the seat belt body 100) is in a tightened state, the belt body 131 pulls the fixing buckle 133 to move along the second direction D2, so as to push the pushing member 380 along the second direction D2 through the pushing member 210 provided on the fixing buckle 133, so that the pushing member 380 moves from the third position to the fourth position. During this process, the elastic rib 382 of the pushing member 380 abuts against the pushing inclined surface 371 in the limiting sleeve 370 and gradually undergoes elastic deformation. When the pushing member 380 moves to the fourth position, the two pushing protrusions 3822 provided on both sides of the elastic body 3821 lose the abutting action of the pushing inclined surface 371. Then, under the elastic force of the elastic body 3821, they impact the impact portion 372 of the limiting sleeve 370 to generate a reminder sound similar to "click" as a reminder signal.

[0107] Further, as Figures 15 to 17 shown, the fourth reset assembly 250 constantly moves the pushing member 380 in the opposite direction of the second direction D2. Specifically, the fourth reset assembly 250 includes a first elastic member 251 and a second elastic member 252. The first elastic member 251 can be a spring. The two ends of the first elastic member 251 respectively abut against the fixing buckle 133 and the vehicle body 10. Specifically, a limiting protrusion 12a4 is provided on the bottom surface of the seat portion 12a. One end of the first elastic member 251 is sleeved on the limiting protrusion 12a4 and abuts against the bottom surface of the seat portion 12a, and the other end of the first elastic member 251 is sleeved on the limiting post 1331 on the fixing buckle 133 and abuts against the fixing buckle 133, so as to prevent the first elastic member 251 from shifting during deformation. The second elastic member 252 can also be a spring. The two ends of the second elastic member 252 respectively abut against the pushing member 380 and the limiting sleeve 370. Specifically, the second elastic member 252 is sleeved outside the elastic rib 382. One end of the second elastic member 252 abuts against the pushing base 381, and an abutting protrusion 375 is further provided in the limiting sleeve 370. The other end of the second elastic member 252 abuts against the abutting protrusion 375, so as to prevent the second elastic member 252 from shifting during deformation. At the same time, setting the first elastic member 251 and the second elastic member 252 is beneficial to the fixing buckle 133 to move smoothly along the second direction D2 or the opposite direction of the second direction D2.

[0108] Thus, when the belt body 131 is tightened, that is, switched from the relaxed state to the tightened state, as Figures 16 to 17 shown, the belt body 131 pulls the fixed buckle 133 to move along the second direction D2, so as to push the pushing member 210 provided on the fixed buckle 133 to press the pushing member 380 along the second direction D2, so that the pushing member 380 moves from the third position to the fourth position. During this process, the elastic rib 382 of the pushing member 380 abuts against the pushing inclined surface 371 in the limiting sleeve 370 and gradually undergoes elastic deformation. The first elastic member 251 and the second elastic member 252 are also compressed and undergo elastic deformation during this process. When the pushing member 380 moves to the fourth position, the two pushing protrusions 3822 provided on both sides of the elastic body 3821 lose the abutting action of the pushing inclined surface 371, so that under the elastic force of the elastic body 3821, they impact the impact portion 372 of the limiting sleeve 370 to generate a reminder sound similar to "click" as a reminder signal to remind the caregiver that the belt body 131 has been tightened in place.

[0109] When the belt buckle 132 (or the shoulder belt buckle 112) is disengaged from the hip belt buckle, or when the belt body 131 is stretched and loosened, as Figures 17 to 16 shown, the fixed buckle 133 will move in the opposite direction of the second direction D2 under the elastic force of the first elastic member 251 and the second elastic member 252, so that the pushing member 380 is reset from the fourth position to the third position.

[0110] The above-mentioned seat belt assembly 20 and the vehicle body 10 at least have the following technical effects:

[0111] In the seat belt assembly 20 applied to the child vehicle, when the seat belt body 100 is in the tightened state, the seat belt body 100 can drive the linkage mechanism 200, and drive the reminder mechanism 300 connected thereto to act through the drive mechanism 200 so that the reminder mechanism 300 generates a reminder signal, so that the caregiver knows that the seat belt body 100 has been tightened in place, so as to avoid the situation that the seat belt body 100 is not fastened or over-fastened.

[0112] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0113] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
