[0081] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0082] The infant carrier of the present invention includes a support unit, a seat belt, and a buckle locking indicator structure. The support unit is used to carry an infant, and the seat belt can secure the infant to the support unit via the buckle locking indicator structure. The infant carrier can be a child car seat, stroller, high chair, etc. Since the structures of the support unit and seat belt are well known to those skilled in the art, they will not be described in detail here. The specific structure of the locking indicator structure is as follows:

[0083] Example 1:

[0084] Please see Figures 4 to 7The buckle locking indicator structure 100 of the present invention includes a male buckle 1, a female buckle 2, and an indicator 3. The female buckle 2 has an indicator window 21. The indicator 3 is disposed inside the female buckle 2 and partially exposed through the indicator window 21. The indicator 3 has a first indicator portion 31 and a second indicator portion 32. The indication of the first indicator portion 31 is different from that of the second indicator portion 32. By engaging the male buckle 1 and the female buckle 2, the indicator 3 is moved relative to the indicator window 21, thereby exposing one of the first indicator portion 31 and the second indicator portion 32 through the indicator window 21. By releasing the male buckle 1 and the female buckle 2, the indicator 3 is moved back to its original position relative to the indicator window 21, thereby exposing the other of the first indicator portion 31 and the second indicator portion 32 through the indicator window 21. The safety belt can be locked or unlocked by the male buckle 1 and the female buckle 2, thereby restraining or releasing the infant on the support. The male buckle 1 and female buckle 2 each have different indicators for fastening and unlocking, serving as reminders for the user to distinguish the locked or unlocked state of the infant vehicle's seatbelt, thus improving the safety of the infant vehicle. The first indicator 31 and the second indicator 32 are provided with different colors to help the user distinguish the fastened and unlocked states of the male buckle 1 and female buckle 2. Specifically, the first indicator 31 is green, and the second indicator 32 is red. When the male buckle 1 and female buckle 2 are fastened, the first indicator 31 is green and the indicator window 21 is displayed, indicating that the fastening is complete. When the male buckle 1 and female buckle 2 are unlocked, the second indicator 32 is red and the indicator window 21 is displayed, indicating that the fastener is not fastened or not fully fastened. However, this is not a strict rule; for example, the second indicator 32 can also be yellow or gray, etc. In other embodiments, the first indicator 31 and the second indicator 32 can also be distinguished by using different text. Specifically, the female buckle 2 has a connector 26 for inserting the male buckle 1. Preferably, the buckle locking indicator structure 100 also includes a release operation member 4, which is movably disposed on the female buckle 2. By driving the release operation member 4 to move, the male buckle 1 and the female buckle 2 are released.

[0085] Please see Figure 3 and Figure 5 The female buckle 2 includes an upper cover 28 and a lower cover 29, which are connected and form an accommodating space. However, the structure of the female buckle 2 including the upper cover 28 and the lower cover 29 is not limited to this embodiment; the female buckle 2 in other embodiments may also include an upper cover 28 and a lower cover 29. Furthermore, in other embodiments, the female buckle 2 may also be an integral structure.

[0086] Please see Figures 5 to 7In this embodiment, the fastener locking indicator structure 100 further includes a retaining member 5. The indicator member 3 is fixed to the release operation member 4, and the retaining member 5 is movably disposed within the female buckle 2. When the male buckle 1 and the female buckle 2 are released, the retaining member 5 prevents the release operation member 4 from moving and resetting. When the male buckle 1 and the female buckle 2 are engaged, the male buckle 1 pushes the retaining member 5 to move, causing the retaining member 5 to release the release operation member 4. Specifically, when the male buckle 1 and the female buckle 2 are released, the retaining member 5 abuts against the end of the release operation member 4. Preferably, the fastener locking indicator structure 100 further includes a first elastic member 61, which is disposed between the release operation member 4 and the female buckle 2 along the moving direction of the release operation member 4. By moving and compressing the first elastic member 61, the male buckle 1 and the female buckle 2 are released. Furthermore, the fastener locking indicator structure 100 also includes a second elastic element 62, which is disposed between the retainer 5 and the female buckle 2 along the moving direction of the retainer 5; when the male buckle 1 pushes the retainer 5 to move, the retainer 5 compresses the second elastic element 62. However, this is not a limitation. For example, if the release operation member 4 adopts an elastic structure, then the first elastic element 61 may not be provided; if the retainer 5 adopts an elastic structure, then the second elastic element 62 may not be provided.

[0087] Please see Figure 6 and Figure 7 After the male buckle 1 and female buckle 2 are released, the second elastic member 62 pushes the retaining member 5 to move, so that the retaining member 5 blocks the release operation member 4 from moving and resetting. The release operation member 4 remains in the released position, and the second indicator part 32 of the release operation member 4 is located below the indicator window 21. At this time, the second indicator part 32 exposes the indicator window 21 and the exposed color is red, indicating that it is not fastened or not fastened in place. When the male buckle 1 and female buckle 2 are fastened, the male buckle 1 pushes the retaining member 5 to move and compresses the second elastic member 62. The retaining member 5 releases the release operation member 4, and the release operation member 4 moves and resets under the action of the first elastic member 61. At this time, the release operation member 4 is in the locked position, and the first indicator part 31 of the release operation member 4 is located below the indicator window 21. At this time, the first indicator part 31 exposes the indicator window 21 and the exposed color is green, indicating that it is fastened in place.

[0088] Please see Figure 7 In this embodiment, the retainer 5 is provided with a first inclined surface 51. The male buckle 1 pushes against the first inclined surface 51 to drive the retainer 5 to move. When the male buckle 1 is inserted into the female buckle 2 and engaged with the female buckle 2, the male buckle 1 can push against the first inclined surface 51 of the retainer 5, thereby driving the retainer 5 to move to release the release operation member 4 and compress the second elastic member 62. The release operation member 4 moves and resets under the action of the first elastic member 61.

[0089] In this embodiment, the female buckle 2 may also be provided with, for example... Figure 14The third elastic element 64 shown is specifically provided in the female buckle 2; when the male buckle 1 and the female buckle 2 are engaged, the male buckle 1 abuts against the third elastic element 64 and causes the third elastic element 64 to deform; when the male buckle 1 and the female buckle 2 are released, the third elastic element 64 pops the male buckle 1 out of the female buckle 2.

[0090] Please see Figure 14 The female buckle 2 has a movable female buckle engagement part 22 inside, and a third elastic member 64 is connected to the female buckle engagement part 22. The male buckle 1 has a male buckle engagement part 11. The male buckle 1 is inserted into the female buckle 2 and engages with the female buckle engagement part 22 to fasten the female buckle 2. During the process of the male buckle 1 being inserted into the female buckle 2 and engaging with the female buckle 2, the male buckle 1 first moves and pushes the female buckle engagement part 22 to move and deform the third elastic member 64. Then, the male buckle 1 moves and pushes the third elastic member 64 to deform. Under the action of the elastic restoring force of the deformed third elastic member 64, the female buckle engagement part 22 moves back to its original position and engages with the male buckle engagement part 11, thereby realizing the fastening of the male buckle 1 and the female buckle 2. Specifically, the female snap-fit ​​portion 22 includes a first female snap-fit ​​portion 221 and a second female snap-fit ​​portion 222. The first female snap-fit ​​portion 221 and the second female snap-fit ​​portion 222 are movably disposed within the female snap 2. The first female snap-fit ​​portion 221 and the second female snap-fit ​​portion 222 can respectively engage with the male snap-fit ​​portion 11. One end of the third elastic member 64 is connected to the first female snap-fit ​​portion 221, and the other end of the third elastic member 64 is connected to the second female snap-fit ​​portion 222. The middle part of the third elastic member 64 is used for the male snap 1 to abut against. However, this is not a limitation. For example, the female snap-fit ​​portion 22 may also only have a first female snap-fit ​​portion 221 or a second female snap-fit ​​portion 222. More specifically, the first female snap-fit ​​portion 221 and the second female snap-fit ​​portion 222 are arranged symmetrically, but this is not a limitation. For example, the first female snap-fit ​​portion 221 and the second female snap-fit ​​portion 222 may also be arranged vertically staggered. During the process of inserting the male buckle 1 into the female buckle 2 and engaging with it, the male buckle 1 first pushes the first female buckle engaging part 221 and the second female buckle engaging part 222 away from each other, and causes the two ends of the third elastic member 64 to deform. Then, under the action of the third elastic member 64, the first female buckle engaging part 221 and the second female buckle engaging part 222 move towards each other, thereby engaging with the male buckle engaging part 11, thus realizing the engagement of the male buckle 1 and the female buckle 2.

[0091] Please see Figures 1 to 2 and combined Figure 14The male snap fastener 11 includes a first male snap fastener 111 and a second male snap fastener 112. The first male snap fastener 111 can engage with the first female snap fastener 221, and the second male snap fastener 112 can engage with the second female snap fastener 222. When the male snap fastener 1 and the female snap fastener 2 are engaged, the first male snap fastener 111 engages with the first female snap fastener 221, and the second male snap fastener 112 engages with the second female snap fastener 222. Furthermore, the male buckle 1 includes a first male buckle body 121 and a second male buckle body 122. The first male buckle body 121 is provided with a male buckle protrusion 121a, and the second male buckle body 122 is provided with a male buckle groove 122a. The male buckle groove 122a is engaged with the male buckle protrusion 121a. The first male buckle body 121 is connected to the first male buckle engaging part 111, and the second male buckle body 122 is connected to the second male buckle engaging part 112. Therefore, the male buckle 1 can be assembled by engaging the male buckle protrusion 121a of the first male buckle body 121 with the male buckle groove 122a of the second male buckle body 122; the male buckle 1 can also be disassembled by detaching the male buckle protrusion 121a of the first male buckle body 121 from the male buckle groove 122a of the second male buckle body 122, thereby facilitating the replacement of damaged first male buckle body 121, second male buckle body 122, first male buckle engaging part 111, or second male buckle engaging part 112. However, the structure of the male buckle 1 is not limited to this. For example, the male buckle 1 can also adopt a one-piece male buckle body 12, directly connecting the male buckle body 12 to the first male buckle engaging part 111 and the second male buckle engaging part 112. More specifically, the first male buckle body 121 and the second male buckle body 122 are spliced ​​together, with one end of the first male buckle engaging part 111 and one end of the second male buckle engaging part 112 overlapping, but this is not a limitation.

[0092] Please see Figure 14 and Figure 15The female latching part 22 is provided with a driving pin 23, and the release operation member 4 is provided with a driving groove 41, into which the driving pin 23 is inserted. By driving the release operation member 4 to slide, the release operation member 4 drives the female latching part 22 to move through the driving groove 41, so that the female latching part 22 disengages from the male latching part 11. Specifically, both the first female latching part 221 and the second female latching part 222 are provided with driving pins 23, and the release operation member 4 is provided with two driving grooves 41. After the male buckle 1 and female buckle 2 are engaged, when it is necessary to release the lock, the release operation member 4 is driven to slide and compress the first elastic member 61. This causes the release operation member 4 to drive the first female buckle engagement part 221 and the second female buckle engagement part 222 to move away from each other through the drive groove 41. This causes the two ends of the third elastic member 64 to deform. The first female buckle engagement part 221 disengages from the first male buckle engagement part 111, and the second female buckle engagement part 222 disengages from the second male buckle engagement part 112. The third elastic member 64 ejects the male buckle 1 from the female buckle 2. Under the action of the third elastic member 64, the first female buckle engagement part 221 and the second female buckle engagement part 222 move towards each other and reset.

[0093] Example 2:

[0094] Please see Figures 10 to 13The buckle locking indicator structure 100 of the present invention includes a male buckle 1, a female buckle 2, and an indicator 3. The female buckle 2 has an indicator window 21. The indicator 3 is disposed inside the female buckle 2 and partially exposed through the indicator window 21. The indicator 3 has a first indicator portion 31 and a second indicator portion 32. The indication of the first indicator portion 31 is different from that of the second indicator portion 32. By engaging the male buckle 1 and the female buckle 2, the indicator 3 is moved relative to the indicator window 21, thereby exposing one of the first indicator portion 31 and the second indicator portion 32 through the indicator window 21. By releasing the male buckle 1 and the female buckle 2, the indicator 3 is moved back to its original position relative to the indicator window 21, thereby exposing the other of the first indicator portion 31 and the second indicator portion 32 through the indicator window 21. The safety belt can be locked or unlocked by the male buckle 1 and the female buckle 2, thereby restraining or releasing the infant on the support. The male buckle 1 and female buckle 2 each have different indicators for fastening and unlocking, serving as reminders for the user to distinguish the locked or unlocked state of the infant vehicle's seatbelt, thus improving the safety of the infant vehicle. Specifically, the first indicator 31 and the second indicator 32 are provided with different colors to help the user distinguish the fastened and unlocked states of the male buckle 1 and female buckle 2. Specifically, the first indicator 31 is green, and the second indicator 32 is red. When the male buckle 1 and female buckle 2 are fastened, the first indicator 31 is green and the indicator window 21 is displayed, indicating that the fastening is complete. When the male buckle 1 and female buckle 2 are unlocked, the second indicator 32 is red and the indicator window 21 is displayed, indicating that the fastener is not fastened or not fully fastened. However, this is not a limitation; for example, the second indicator 32 can also be yellow or gray. In other embodiments, the first indicator 31 and the second indicator 32 can also be distinguished by using different text. Specifically, the female buckle 2 has a connector 26 for inserting the male buckle 1. Preferably, the buckle locking indicator structure 100 also includes a release operation member 4, which is movably disposed on the female buckle 2. By driving the release operation member 4 to move, the male buckle 1 and the female buckle 2 are released.

[0095] Please see Figure 12 and Figure 13The fastener locking indicator structure 100 also includes a retaining member 5. The indicator member 3 is fixed to the release operation member 4, and the retaining member 5 is movably disposed within the female buckle 2. When the male buckle 1 and the female buckle 2 are released, the retaining member 5 prevents the release operation member 4 from moving and resetting. When the male buckle 1 and the female buckle 2 are engaged, the male buckle 1 pushes the retaining member 5 to move, causing the retaining member 5 to release the release operation member 4. Preferably, the fastener locking indicator structure 100 also includes a first elastic member 61, which is disposed between the release operation member 4 and the female buckle 2 along the moving direction of the release operation member 4. By moving and compressing the first elastic member 61, the male buckle 1 and the female buckle 2 are released. Further, the fastener locking indicator structure 100 also includes a second elastic member 62, which is disposed between the retaining member 5 and the female buckle 2 along the moving direction of the retaining member 5. When the male buckle 1 pushes the retaining member 5 to move, the retaining member 5 compresses the second elastic member 62. When male buckle 1 and female buckle 2 are engaged, male buckle 1 pushes the retaining member 5 to move and compresses the second elastic member 62. The retaining member 5 releases the release operating member 4, which moves back to its original position under the action of the first elastic member 61. The release operating member 4 is in the locked position, and the first indicator part 31 of the release operating member 4 is located below the indicator window 21. At this time, the first indicator part 31 exposes the indicator window 21, and the exposed color is green, indicating that the engagement is complete. After male buckle 1 and female buckle 2 are released, the second elastic member 62 pushes the retaining member 5 to move, causing the retaining member 5 to block the release operating member 4 from moving back to its original position. The release operating member 4 remains in the released position, and the second indicator part 32 of the release operating member 4 is located below the indicator window 21. At this time, the second indicator part 32 exposes the indicator window 21, and the exposed color is red, indicating that the engagement is not complete or not fully engaged. However, this is not a limitation. For example, if the release mechanism 4 can adopt an elastic structure, then the first elastic element 61 may not be provided; if the retaining element 5 can adopt an elastic structure, then the second elastic element 62 may not be provided.

[0096] Please see Figure 16 In this embodiment, the retaining member 5 is provided with a positioning protrusion 52, and the release operation member 4 is provided with a positioning groove 42. When the male buckle 1 and the female buckle 2 are released, the positioning protrusion 52 is inserted into the positioning groove 42, thereby locking the release operation member 4 in the release position. The second indicator part 32 of the release operation member 4 is located below the indicator window 21. The second indicator part 32 exposes the indicator window 21, and the exposed color is red, indicating that it is not engaged or not engaged properly. When the male buckle 1 and the female buckle 2 are engaged, the male buckle 1 pushes the retaining member 5 to move, causing the positioning protrusion 52 of the retaining member 5 to exit the positioning groove 42, thereby releasing the release operation member 4. Under the action of the first elastic member 61, the release operation member 4 moves and resets. At this time, the release operation member 4 is in the locked position. The first indicator part 31 of the release operation member 4 is located below the indicator window 21. The first indicator part 31 exposes the indicator window 21, and the exposed color is green, indicating that it is engaged properly.

[0097] Please see Figure 12 and Figure 13 In this embodiment, the retaining member 5 is provided with a first inclined surface 51. The male buckle 1 pushes against the first inclined surface 51 to drive the retaining member 5 to move. When the male buckle 1 is inserted into the female buckle 2 and engaged with the female buckle 2, the male buckle 1 can push against the first inclined surface 51 of the retaining member 5, thereby driving the retaining member 5 to move, releasing the release operation member 4 and compressing the second elastic member 62. The release operation member 4 moves back to its original position under the action of the first elastic member 61. Further, the buckle locking indicator structure 100 also includes a transmission member 63, which is movably disposed in the female buckle 2 and abuts against the first inclined surface 51. When the male buckle 1 is engaged with the female buckle 2, the male buckle 1 pushes against the transmission member 63, causing the transmission member 63 to push the retaining member 5 to move. Specifically, the transmission member 63 is provided with a second inclined surface 631, which abuts against the first inclined surface 51. The moving direction of the transmission member 63 is the same as the direction in which the male buckle 1 moves into the female buckle 2. The moving direction of the transmission member 63 is perpendicular to the moving direction of the retaining member 5, but is not limited thereto.

[0098] Please see Figure 12 and 14 In this embodiment, a third elastic member 64 is connected to one side of the transmission member 63. When the male buckle 1 and the female buckle 2 are engaged, the male buckle 1 pushes the transmission member 63 to move through the third elastic member 64, causing the third elastic member 64 to deform. When the male buckle 1 and the female buckle 2 are released, the third elastic member 64 pops the male buckle 1 out of the female buckle 2, allowing the male buckle 1 and the female buckle 2 to quickly disengage and release. Specifically, the transmission member 63 is provided with a slot 632, and the third elastic member 64 is engaged in the slot 632, but this is not a limitation. For example, the third elastic member 64 can also be directly fixedly connected to the transmission member 63.

[0099] Please see Figure 14The female buckle 2 has a movable female buckle engagement part 22 inside, and a third elastic member 64 is connected to the female buckle engagement part 22. The male buckle 1 has a male buckle engagement part 11. The male buckle 1 is inserted into the female buckle 2 and engages with the female buckle engagement part 22 to fasten the female buckle 2. During the process of the male buckle 1 being inserted into the female buckle 2 and engaging with the female buckle 2, the male buckle 1 first pushes the female buckle engagement part 22 to move and deforms the third elastic member 64. Then, the male buckle 1 pushes the transmission member 63 to move through the third elastic member 64. The movement of the transmission member 63 pushes the holding member 5 to move. The holding member 5 releases the release operation member 4 and compresses the second elastic member 62. Under the action of the elastic restoring force of the deformation of the third elastic member 64, the female buckle engagement part 22 moves back to its original position and engages with the male buckle engagement part 11, thereby realizing the fastening of the male buckle 1 and the female buckle 2. Specifically, the female latching portion 22 includes a first female latching portion 221 and a second female latching portion 222. The first female latching portion 221 and the second female latching portion 222 are movably disposed within the female latch 2. The first female latching portion 221 and the second female latching portion 222 can respectively engage with the male latching portion 11. One end of the third elastic member 64 is connected to the first female latching portion 221, and the other end of the third elastic member 64 is connected to the second female latching portion 222. The middle part of the third elastic member 64 is connected to the transmission member 63. However, this is not a limitation. For example, the female latching portion 22 may only have a first female latching portion 221 or a second female latching portion 222. More specifically, the first female latching portion 221 and the second female latching portion 222 are arranged symmetrically, but this is not a limitation. For example, the first female latching portion 221 and the second female latching portion 222 may also be arranged vertically staggered. During the process of inserting the male buckle 1 into the female buckle 2 and engaging with it, the male buckle 1 first pushes the first female buckle engaging part 221 and the second female buckle engaging part 222 away from each other, and causes the two ends of the third elastic member 64 to deform. Then, under the action of the third elastic member 64, the first female buckle engaging part 221 and the second female buckle engaging part 222 move towards each other, thereby engaging with the male buckle engaging part 11, thus realizing the engagement of the male buckle 1 and the female buckle 2.

[0100] Please continue reading. Figure 8 and Figure 9The male snap fastener 11 includes a first male snap fastener 111 and a second male snap fastener 112. The first male snap fastener 111 can engage with the first female snap fastener 221, and the second male snap fastener 112 can engage with the second female snap fastener 222. When the male snap fastener 1 and the female snap fastener 2 are engaged, the first male snap fastener 111 engages with the first female snap fastener 221, and the second male snap fastener 112 engages with the second female snap fastener 222. Furthermore, the male buckle 1 includes a first male buckle body 121 and a second male buckle body 122. The first male buckle body 121 is provided with a male buckle protrusion 121a, and the second male buckle body 122 is provided with a male buckle groove 122a. The male buckle groove 122a is engaged with the male buckle protrusion 121a. The first male buckle body 121 is connected to the first male buckle engaging part 111, and the second male buckle body 122 is connected to the second male buckle engaging part 112. Therefore, the male buckle 1 can be assembled by engaging the male buckle protrusion 121a of the first male buckle body 121 with the male buckle groove 122a of the second male buckle body 122; the male buckle 1 can also be disassembled by detaching the male buckle protrusion 121a of the first male buckle body 121 from the male buckle groove 122a of the second male buckle body 122, thereby facilitating the replacement of damaged first male buckle body 121, second male buckle body 122, first male buckle engaging part 111, or second male buckle engaging part 112. However, the structure of the male buckle 1 is not limited to this. For example, the male buckle 1 can also adopt a one-piece male buckle body 12, directly connecting the male buckle body 12 to the first male buckle engaging part 111 and the second male buckle engaging part 112. Specifically, the first male buckle body 121 and the second male buckle body 122 are spliced ​​together, with one end of the first male buckle engaging part 111 and one end of the second male buckle engaging part 112 overlapping, but this is not a limitation.

[0101] Please see Figure 14 and Figure 15The female latching part 22 is provided with a driving pin 23, and the release operation member 4 is provided with a driving groove 41, into which the driving pin 23 is inserted. By driving the release operation member 4 to slide, the release operation member 4 drives the female latching part 22 to move through the driving groove 41, so that the female latching part 22 disengages from the male latching part 11. Specifically, both the first female latching part 221 and the second female latching part 222 are provided with driving pins 23, and the release operation member 4 is provided with two driving grooves 41. After the male buckle 1 and female buckle 2 are engaged, when it is necessary to release the lock, the release operation member 4 is driven to slide and compress the first elastic member 61. This causes the release operation member 4 to drive the first female buckle engagement part 221 and the second female buckle engagement part 222 to move away from each other through the drive groove 41. This causes the two ends of the third elastic member 64 to deform. The first female buckle engagement part 221 disengages from the first male buckle engagement part 111, and the second female buckle engagement part 222 disengages from the second male buckle engagement part 112. The third elastic member 64 ejects the male buckle 1 from the female buckle 2. Under the action of the third elastic member 64, the first female buckle engagement part 221 and the second female buckle engagement part 222 move towards each other and reset.

[0102] Example 3:

[0103] Please see Figure 19 , Figure 20 , Figure 22 and Figure 23 The fastener locking indicator structure 100 of the present invention includes a male buckle 1, a female buckle 2, and an indicator 3. The female buckle 2 is provided with an indicator window 21, and references... Figure 20As shown, the indicator window 21 is located above the female buckle 2, so that the indicator window 21 is not easily blocked by the crotch strap or seat belt, preventing the indicator window 21 from being invisible to the consumer and thus failing to provide a prompt. The indicator 3 is disposed inside the female buckle 2 and partially protrudes from the indicator window 21. The indicator 3 has a first indicator part 31 and a second indicator part 32, and the indications of the first indicator part 31 and the second indicator part 32 are different. By engaging the male buckle 1 and the female buckle 2, the indicator 3 is driven to move relative to the indicator window 21, thereby exposing one of the first indicator part 31 and the second indicator part 32 in the indicator window 21. By releasing the male buckle 1 and the female buckle 2, the indicator 3 is driven to move back to its original position relative to the indicator window 21, thereby exposing the other of the first indicator part 31 and the second indicator part 32 in the indicator window 21. The seat belt can be locked or unlocked by the male buckle 1 and the female buckle 2, thereby restraining or releasing the infant on the support. The male buckle 1 and female buckle 2 each have different indicators for fastening and unlocking, serving as reminders for the user to distinguish the locked or unlocked state of the infant vehicle's seatbelt, thus improving the safety of the infant vehicle. Specifically, the first indicator 31 and the second indicator 32 are provided with different colors to help the user distinguish the fastened and unlocked states of the male buckle 1 and female buckle 2. Specifically, the first indicator 31 is green, and the second indicator 32 is red. When the male buckle 1 and female buckle 2 are fastened, the first indicator 31 is green and the indicator window 21 is displayed, indicating that the fastening is complete. When the male buckle 1 and female buckle 2 are unlocked, the second indicator 32 is red and the indicator window 21 is displayed, indicating that the fastener is not fastened or not fully fastened. However, this is not a limitation; for example, the second indicator 32 can also be yellow or gray. In other embodiments, the first indicator 31 and the second indicator 32 can also be distinguished by using different text. Specifically, the female buckle 2 has a connector 26 for inserting the male buckle 1. Preferably, the buckle locking indicator structure 100 also includes a release operation member 4, which is movably disposed on the female buckle 2 and located below the female buckle 2. By driving the release operation member 4 to move, the male buckle 1 and the female buckle 2 are released.

[0104] Please see Figures 21 to 23In this embodiment, the indicator 3 and the release operation component 4 are separated, thus eliminating the need for a retaining component, simplifying the fastener structure, facilitating production and processing, and effectively preventing misleading consumers while ensuring the accuracy and reliability of the prompts. When the male buckle 1 and female buckle 2 are engaged, the male buckle 1 pushes the indicator 3 to move; when the male buckle 1 and female buckle 2 are released, the indicator 3 moves back to its original position. Furthermore, the fastener locking indicator structure 100 also includes a fourth elastic element 65, which is positioned between the indicator 3 and the female buckle 2 along the moving direction of the indicator 3. When the male buckle 1 pushes the indicator 3 to move, the indicator 3 compresses the fourth elastic element 65. When the male buckle 1 and female buckle 2 are engaged, the male buckle 1 pushes the indicator 3 to move and compresses the fourth elastic element 65. The first indicator part 31 of the indicator 3 is located below the indicator window 21. At this time, the first indicator part 31 exposes the indicator window 21, and the exposed color is green, indicating that the fastener is in place. When the male buckle 1 and female buckle 2 are released, the male buckle 1 releases the indicator 3. The indicator 3 moves back to its original position under the action of the fourth elastic member 65. The second indicator part 32 of the indicator 3 is located below the indicator window 21. At this time, the second indicator part 32 exposes the indicator window 21, and the exposed color is red, indicating that it is not engaged or not fully engaged. Furthermore, the buckle locking indicator structure 100 also includes a sixth elastic member 68, which is disposed between the release operation member 4 and the female buckle 2 along the moving direction of the release operation member 4. By driving the release operation member 4 to move and compress the sixth elastic member 68, the male buckle 1 and female buckle 2 are released. When the release operation member 4 is released, it can move back to its original position under the action of the sixth elastic member 68.

[0105] Please see Figure 25 The female buckle 2 is provided with a third elastic element 64; when the male buckle 1 and the female buckle 2 are fastened together, the male buckle 1 abuts against the third elastic element 64 and causes the third elastic element 64 to deform; when the male buckle 1 and the female buckle 2 are released, the third elastic element 64 pushes the male buckle 1 out of the female buckle 2.

[0106] Please continue reading. Figure 25The female buckle 2 has a movable female buckle engagement part 22 inside, and a third elastic member 64 is connected to the female buckle engagement part 22. The male buckle 1 has a male buckle engagement part 11. The male buckle 1 is inserted into the female buckle 2 and engages with the female buckle engagement part 22 to fasten the female buckle 2. During the process of the male buckle 1 being inserted into the female buckle 2 and engaging with the female buckle 2, the male buckle 1 first moves and pushes the female buckle engagement part 22 to move and deform the third elastic member 64. Then, the male buckle 1 moves and pushes the third elastic member 64 to deform. Under the action of the elastic restoring force of the deformed third elastic member 64, the female buckle engagement part 22 moves back to its original position and engages with the male buckle engagement part 11, thereby realizing the fastening of the male buckle 1 and the female buckle 2. Specifically, the female snap-fit ​​portion 22 includes a first female snap-fit ​​portion 221 and a second female snap-fit ​​portion 222. The first female snap-fit ​​portion 221 and the second female snap-fit ​​portion 222 are movably disposed within the female snap 2. The first female snap-fit ​​portion 221 and the second female snap-fit ​​portion 222 can respectively engage with the male snap-fit ​​portion 11. One end of the third elastic member 64 is connected to the first female snap-fit ​​portion 221, and the other end of the third elastic member 64 is connected to the second female snap-fit ​​portion 222. The middle part of the third elastic member 64 is used for the male snap 1 to abut against. However, this is not a limitation. For example, the female snap-fit ​​portion 22 may also only have a first female snap-fit ​​portion 221 or a second female snap-fit ​​portion 222. More specifically, the first female snap-fit ​​portion 221 and the second female snap-fit ​​portion 222 are arranged symmetrically, but this is not a limitation. For example, the first female snap-fit ​​portion 221 and the second female snap-fit ​​portion 222 may also be arranged vertically staggered. During the process of inserting the male buckle 1 into the female buckle 2 and engaging with it, the male buckle 1 first pushes the first female buckle engaging part 221 and the second female buckle engaging part 222 away from each other, and causes the two ends of the third elastic member 64 to deform. Then, under the action of the third elastic member 64, the first female buckle engaging part 221 and the second female buckle engaging part 222 move towards each other, thereby engaging with the male buckle engaging part 11, thus realizing the engagement of the male buckle 1 and the female buckle 2.

[0107] Please see Figure 17 and Figure 18The male snap fastener 11 includes a first male snap fastener 111 and a second male snap fastener 112. The first male snap fastener 111 can engage with the first female snap fastener 221, and the second male snap fastener 112 can engage with the second female snap fastener 222. When the male snap fastener 1 and the female snap fastener 2 are engaged, the first male snap fastener 111 engages with the first female snap fastener 221, and the second male snap fastener 112 engages with the second female snap fastener 222. Furthermore, the male buckle 1 includes a first male buckle body 121 and a second male buckle body 122. The first male buckle body 121 is provided with a male buckle protrusion 121a, and the second male buckle body 122 is provided with a male buckle groove 122a. The male buckle groove 122a is engaged with the male buckle protrusion 121a. The first male buckle body 121 is connected to the first male buckle engaging part 111, and the second male buckle body 122 is connected to the second male buckle engaging part 112. Therefore, the male buckle 1 can be assembled by engaging the male buckle protrusion 121a of the first male buckle body 121 with the male buckle groove 122a of the second male buckle body 122; the male buckle 1 can also be disassembled by detaching the male buckle protrusion 121a of the first male buckle body 121 from the male buckle groove 122a of the second male buckle body 122, thereby facilitating the replacement of damaged first male buckle body 121, second male buckle body 122, first male buckle engaging part 111, or second male buckle engaging part 112. However, the structure of the male buckle 1 is not limited to this. For example, the male buckle 1 can also adopt a one-piece male buckle body 12, directly connecting the male buckle body 12 to the first male buckle engaging part 111 and the second male buckle engaging part 112. More specifically, the first male buckle body 121 and the second male buckle body 122 are spliced ​​together, with one end of the first male buckle engaging part 111 and one end of the second male buckle engaging part 112 overlapping, but this is not a limitation.

[0108] Please see Figure 26 and Figure 27The female latching part 22 is provided with a driving pin 23, and the release operation member 4 is provided with a driving groove 41, into which the driving pin 23 is inserted. By driving the release operation member 4 to slide, the release operation member 4 drives the female latching part 22 to move through the driving groove 41, so that the female latching part 22 disengages from the male latching part 11. Specifically, both the first female latching part 221 and the second female latching part 222 are provided with driving pins 23, and the release operation member 4 is provided with two driving grooves 41. After the male buckle 1 and female buckle 2 are engaged, when it is necessary to release the lock, the release operation member 4 is driven to slide and compress the sixth elastic member 68. This causes the release operation member 4 to drive the first female buckle engagement part 221 and the second female buckle engagement part 222 to move away from each other through the drive groove 41, and causes the two ends of the third elastic member 64 to deform. The first female buckle engagement part 221 disengages from the first male buckle engagement part 111, and the second female buckle engagement part 222 disengages from the second male buckle engagement part 112. The third elastic member 64 then ejects the male buckle 1 from the female buckle 2. When the release operation member 4 is released, it can move back to its original position under the action of the sixth elastic member 68, and the first female buckle engagement part 221 and the second female buckle engagement part 222 move back to their original position under the action of the third elastic member 64.

[0109] Please see Figure 24 and Figure 25 The indicator 3 has a switch drive rib 33, and the female buckle 2 has an electronic warning switch 25 inside. When the male buckle 1 pushes the indicator 3 to move, the switch drive rib 33 drives the electronic warning switch 25 to close, thereby activating the electronic indicator function of the buckle. However, this embodiment is not limited to this one; in other embodiments, the indicator 3 may also have a switch drive rib 33, and the female buckle 2 may also have an electronic warning switch 25 inside.

[0110] Please see Figures 35 to 37The buckle locking indicator structure 100 also includes a battery assembly 7 for powering the electronic warning switch 25 to ensure its normal operation. The female buckle 2 has a mounting opening 291, in which the battery assembly 7 is detachably installed. This allows the user to replace the battery when it is depleted, thus improving the buckle's lifespan and functionality. Specifically, the battery assembly 7 includes a battery holder 71 and a battery 72. The battery holder 71 has a battery mounting hole 711, and the battery 72 is installed in the battery mounting hole 711. The battery holder 71 is detachably installed in the mounting opening 291. Preferably, the fastener locking indicator structure 100 further includes a seventh elastic member 81 and a locking member 82. The seventh elastic member 81 is disposed between the battery holder 71 and the female buckle 2. The battery holder 71 presses against the seventh elastic member 81, and the locking member 82 is movably disposed within the female buckle 2, preventing the battery holder 71 from exiting the mounting opening 291. By driving the locking member 82 to move away from the battery holder 71, the seventh elastic member 81 ejects the battery holder 71 from the mounting opening 291. When the battery assembly 7 is installed in the mounting opening 291, the battery holder 71 presses against the seventh elastic member 81, and the locking member 82 prevents the battery holder 71 from exiting the mounting opening 291. When it is necessary to disassemble the battery assembly 7, the locking member 82 is driven to move away from the battery holder 71, and the locking member 82 no longer blocks the battery holder 71, allowing the seventh elastic member 81 to eject the battery holder 71 and the battery 72 together from the mounting opening 291. The detachable structure of the battery assembly 7 is not limited to this embodiment three, but can also be used in embodiment one, embodiment two, or other embodiments.

[0111] Please see Figures 38 to 40One end of the battery holder 71 is provided with a locking groove 712. When the battery holder 71 is located in the mounting opening 291, the locking member 82 is inserted into the locking groove 712 and blocks the battery holder 71. By driving the locking member 82 to move out of the locking groove 712, the locking member 82 moves away from the battery holder 71. Further, one end of the battery holder 71 is provided with an opening 713 extending into the locking groove 712. When the battery holder 71 is located in the mounting opening 291, one end of the locking member 82 passes through the opening 713, and the middle part of the locking member 82 is inserted into the locking groove 712. Specifically, the locking member 82 includes a push rod portion 821 and a locking rod portion 822 connected to the push rod portion 821. The push rod portion 821 passes through the opening 713, and the locking rod portion 822 is inserted into the locking groove 712. The female buckle 2 is provided with a release hole 27 facing the locking member 82. A pin can be inserted into the release hole 27 to push the top rod 821 of the locking member 82, causing the locking member 82 to move. The locking rod 822 then exits the locking groove 712, and the locking member 82 no longer obstructs the battery holder 71. This allows the seventh elastic member 81 to eject the battery holder 71 and battery 72 together from the installation opening 291, facilitating battery replacement. This structure also prevents children from disassembling the battery themselves, avoiding the danger of accidentally swallowing batteries or other components. Therefore, the battery assembly 7 must be removed by an adult with tools, greatly improving safety. More specifically, the release hole 27 is stepped. When the battery holder 71 is located in the installation opening 291, the top rod 821 is inserted into the release hole 27, further locking the battery assembly 7 within the installation opening 291. When a pin is inserted into the release hole 27 and pushes the top rod 821 of the locking member 82, the top rod 821 exits the release hole 27.

[0112] Please see Figure 40 The fastener locking indicator structure 100 also includes an eighth elastic element 83, which is disposed between the locking member 82 and the female buckle 2. When the locking member 82 is driven to move away from the battery holder 71, the locking member 82 presses against the eighth elastic element 83. When the battery assembly 7 exits the mounting port 291, the locking member 82 moves back to its original position under the action of the eighth elastic element 83. Further, the locking member 82 is provided with a release ramp 822a, specifically, the release ramp 822a is disposed on the locking rod portion 822; during the process of inserting the battery holder 71 into the mounting port 291, the battery holder 71 pushes the locking member 82 to move and presses against the eighth elastic element 83 through the release ramp 822a, thereby passing over the locking member 82; after the battery holder 71 is fully inserted, the locking member 82 moves back to its original position under the action of the eighth elastic element 83 and blocks the battery holder 71.

[0113] Example 4:

[0114] Please see Figure 28 , Figure 29 , Figure 33 and Figure 34The buckle locking indicator structure 100 of the present invention includes a male buckle 1, a female buckle 2, and an indicator 3. The female buckle 2 has an indicator window 21. The indicator 3 is disposed inside the female buckle 2 and partially protrudes below the indicator window 21. The indicator 3 has a first indicator portion 31 and a second indicator portion 32. The indication of the first indicator portion 31 is different from that of the second indicator portion 32. By engaging the male buckle 1 and the female buckle 2, the indicator 3 is driven to move relative to the indicator window 21, thereby exposing one of the first indicator portion 31 and the second indicator portion 32 in the indicator window 21. By releasing the male buckle 1 and the female buckle 2, the indicator 3 is driven to move back to its original position relative to the indicator window 21, thereby exposing the other of the first indicator portion 31 and the second indicator portion 32 in the indicator window 21. The safety belt can be locked or unlocked by the male buckle 1 and the female buckle 2, thereby restraining or releasing the infant on the support. The male buckle 1 and female buckle 2 each have different indicators for fastening and unlocking, serving as reminders for the user to distinguish the locked or unlocked state of the infant vehicle's seatbelt, thus improving the safety of the infant vehicle. Specifically, the first indicator 31 and the second indicator 32 are provided with different colors to help the user distinguish the fastened and unlocked states of the male buckle 1 and female buckle 2. Specifically, the first indicator 31 is green, and the second indicator 32 is red. When the male buckle 1 and female buckle 2 are fastened, the first indicator 31 is green and the indicator window 21 is displayed, indicating that the fastening is complete. When the male buckle 1 and female buckle 2 are unlocked, the second indicator 32 is red and the indicator window 21 is displayed, indicating that the fastener is not fastened or not fully fastened. However, this is not a limitation; for example, the second indicator 32 can also be yellow or gray. In other embodiments, the first indicator 31 and the second indicator 32 can also be distinguished by using different text. Specifically, the female buckle 2 has a connector 26 for inserting the male buckle 1. Preferably, the buckle locking indicator structure 100 also includes a release operation member 4, which is movably disposed on the female buckle 2. By driving the release operation member 4 to move, the male buckle 1 and the female buckle 2 are released.

[0115] Please see Figures 32 to 34In this embodiment, the indicator 3 and the unlocking operation component 4 are separated. When the male buckle 1 and the female buckle 2 are engaged, the male buckle 1 pushes the indicator 3 to move. When the male buckle 1 and the female buckle 2 are unlocked, the indicator 3 moves back to its original position. Further, the buckle locking indicator structure 100 also includes a fourth elastic element 65, which is disposed between the indicator 3 and the female buckle 2 along the moving direction of the indicator 3. When the male buckle 1 pushes the indicator 3 to move, the indicator 3 compresses the fourth elastic element 65. When the male buckle 1 and the female buckle 2 are engaged, the male buckle 1 pushes the indicator 3 to move and compresses the fourth elastic element 65. The first indicator part 31 of the indicator 3 is located below the indicator window 21. At this time, the first indicator part 31 exposes the indicator window 21, and the exposed color is green, indicating that the engagement is complete. When the male buckle 1 and female buckle 2 are released, the male buckle 1 releases the indicator 3. The indicator 3 moves back to its original position under the action of the fourth elastic member 65. The second indicator part 32 of the indicator 3 is located below the indicator window 21. At this time, the second indicator part 32 exposes the indicator window 21, and the exposed color is red, indicating that it is not engaged or not fully engaged. Specifically, the female buckle 2 has a mounting member 24, which has a sliding groove 241. The indicator 3 is slidably disposed within the sliding groove 241, and the fourth elastic member 65 is disposed between the indicator 3 and the mounting member 24. However, this is not a limitation.

[0116] Please see Figures 30 to 32 The fastener locking indicator structure 100 also includes a pusher 66, which is movably disposed within the female buckle 2. When the male buckle 1 and the female buckle 2 are engaged, the male buckle 1 pushes the pusher 66, causing the pusher 66 to move the indicator 3. Specifically, the pusher 66 is provided with a guide groove 661, and the indicator 3 is inserted into the guide groove 661. When the male buckle 1 pushes the pusher 66, the pusher 66 first moves relative to the indicator 3 through the guide groove 661, and then the inner wall of the guide groove 661 abuts against the indicator 3, causing the pusher 66 to push the indicator 3 to move. However, this is not a limitation. For example, when the male buckle 1 and the female buckle 2 are engaged, the male buckle 1 can push the pusher 66, causing the pusher 66 to directly push the indicator 3 to move. Furthermore, the fastener locking indicator structure 100 also includes a fifth elastic element 67, which is disposed between the pusher 66 and the female buckle 2 in the direction of movement of the pusher 66. When the male buckle 1 pushes the pusher 66, the pusher 66 compresses the fifth elastic element 67. However, after the male buckle 1 and the female buckle 2 are unlocked, the male buckle 1 releases the pusher 66, and the pusher 66 moves back to its original position under the action of the fifth elastic element 67.

[0117] In summary, the buckle locking indicator structure 100 of the present invention provides an indicator window 21 on the female buckle 2 and two different indicators, a first indicator part 31 and a second indicator part 32, on the indicator member 3. When the male buckle 1 and the female buckle 2 are fastened, one of the first indicator part 31 and the second indicator part 32 faces the indicator window 21; when the male buckle 1 and the female buckle 2 are unlocked, the other of the first indicator part 31 and the second indicator part 32 faces the indicator window 21. Therefore, the male buckle 1 and the female buckle 2 have different corresponding indicators when fastening and unlocking. Thus, the buckle locking indicator structure 100 of the present invention can distinguish the fastening and unlocking states of the buckle, which can serve as a reminder to the user and improve the safety of the buckle. By providing the buckle locking indicator structure 100, the infant vehicle allows the seat belt to be locked or unlocked by the male buckle 1 and the female buckle 2. The locking or unlocking state of the seat belt can be distinguished by the fastening and unlocking states of the buckle, thereby serving as a reminder to the user and improving the safety of the infant vehicle.

[0118] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are within the scope of the present invention.
