Description

[Technical Field]

[0001] The present invention relates to a child carrier according to the clause before the characterising part of claim 1 . [Background technology]

[0002] Child carriers, such as strollers, typically have a foldable frame body for improved practicality and transportability. When using the child carrier, a user can unfold the child carrier into an unfolded state. When not using the child carrier, a user can fold the child carrier into a folded state to reduce the space occupied by the child carrier for easy storage and transportation.

[0003] Conventional folding frame bodies typically include multiple rods, which can be classified into a backrest, a seat, rear legs, front legs, and a handle according to their functions, and a locking device disposed between the rods for locking or unlocking the multiple rods. However, conventional locking devices have a complex structure and cannot simultaneously unlock multiple rods. Furthermore, conventional locking devices are activated by a release button, which requires the user to bend down to operate the release button. Therefore, conventional locking devices are inconvenient to use and leave room for improvement. Summary of the Invention [Problem to be solved by the invention]

[0029] According to one embodiment of the present invention, the restrictive component is a cylinder.

[0030] According to one embodiment of the present invention, a through hole is formed in the second mounting seat and disposed at a position corresponding to the restricting component, and the restricting component slidably passes through the through hole.

[0031] According to one embodiment of the present invention, the drive component includes a pressing component and a driven component. The pressing component is pivotally connected to the first mounting seat. The driven component is movably disposed between the pressing component and the first locking component and is movable between an extended position and a retracted position. The pressing component pivots to drive the driven component to move from the retracted position to the extended position and to press the first locking component from the first locked position to the first unlocked position to enable the folding operation of the folding locking mechanism.

[0041] In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings, which form a part hereof, and which show, by way of illustration, specific embodiments in which the invention may be practiced. In this regard, directional terms such as "top," "bottom," "right," "left," "front," and "back" are used with reference to the orientation of the figures being described. Components of the invention may be positioned in several different orientations. Accordingly, the directional terminology is used for purposes of explanation and is in no way limiting. Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive. Also, the term "connect" is intended to mean either an indirect or direct mechanical connection. Thus, when a first device is coupled to a second device, the connection may be via a direct mechanical connection or an indirect mechanical connection via other devices and connections.

[0042] Please refer to FIGS. 1 to 5. FIG. 1 is a schematic diagram of a child carrier 100 in an unfolded state according to a first embodiment of the present invention. FIG. 2 is a partial cross-sectional view of the child carrier 100 according to the first embodiment of the present invention. FIG. 3 is an enlarged view of portion C of the child carrier 100 shown in FIG. 2 according to the first embodiment of the present invention. FIGS. 4 and 5 are partial views of the child carrier 100 according to the first embodiment of the present invention in different views. As shown in FIGS. 1 to 5, in this embodiment, the child carrier 100 may be a stroller for children and includes a frame body 400 and two folding locking mechanisms 200. The two folding locking mechanisms 200 are disposed on two sides of the frame body 400 and are symmetrical to each other for locking or unlocking different rods of the frame body 400, and enabling or inhibiting the pivotal movement of the different rods. However, the number of folding locking mechanisms 200 is not limited to this embodiment. For example, in another embodiment, child carrier 100 may be a child basket or a child safety seat and may include only one folding locking mechanism on only one side of the frame body of the child basket or child safety seat.

[0043] The folding locking mechanism 200 includes a first mounting seat 1, a second mounting seat 2, a third mounting seat 4, a first locking component 3, a first elastic component 9, and a drive component 1a. The first mounting seat 1, the second mounting seat 2, and the third mounting seat 4 can be connected to three different rods of the frame body 400. The second mounting seat 2 is pivotally connected to the first mounting seat 1. The third mounting seat 4 is pivotally connected to the second mounting seat 2. A chamber is formed between the second mounting seat 2 and the third mounting seat 4. The first locking component 3 is at least partially and movably disposed within the chamber between the second mounting seat 2 and the third mounting seat 4. The first locking component 3 is movable between a first unlocked position and a first locked position along the axial direction of the pivot axes of the second mounting seat 2 and the third mounting seat 4. The first locking component 3, when positioned in the first locking position, can lock the relative pivoting movement between the second mounting seat 2 and the third mounting seat 4. That is, when the first locking component 3 is positioned in the first locking position, the first locking component 3 can inhibit the relative pivoting movement between the second mounting seat 2 and the third mounting seat 4. The first locking component 3, when positioned in the first unlocking position, can unlock the relative pivoting movement between the second mounting seat 2 and the third mounting seat 4. That is, when the first locking component 3 is positioned in the first unlocking position, the first locking component 3 can allow the relative pivoting movement between the second mounting seat 2 and the third mounting seat 4. The first elastic component 9 can provide an elastic force to drive the first locking component 3 to move toward the first locking position. Preferably, in this embodiment, the first elastic component 9 may be a compression spring. However, the present invention is not limited to this embodiment.

[0044] Furthermore, the drive component 1 a is disposed on the first mounting seat 1 and abuts against the first locking component 3 to drive the first locking component 3 to move it from the first locked position to the first unlocked position. In this embodiment, when the first mounting seat 1 and the second mounting seat 2 pivot relative to each other, the drive component 1 a is driven by the relative pivotal movement of the first mounting seat 1 and the second mounting seat 2 to press the first locking component 3 from the first locked position to the first unlocked position. For example, when the rod connected to the first mounting seat 1 operates to pivotally fold relative to the rod connected to the second mounting seat 2, the first mounting seat 1 can be driven to pivotally fold relative to the second mounting seat 2. When the first mounting seat 1 is pivotally folded relative to the second mounting seat 2, the drive component 1a can drive the first lock component 3 to move from the first locked position to the first unlocked position to enable relative pivotal movement between the second mounting seat 2 and the third mounting seat 4, thereby allowing the rod connected to the second mounting seat 2 and the rod connected to the third mounting seat 4 to be pivotally folded relative to each other. In other words, the present invention can utilize the relative pivotal movement of the two rods connected to the first mounting seat 1 and the second mounting seat 2 to unlock the relative pivotal movement of the other two rods. Therefore, the present invention has the advantages of being simple in structure and easy to operate.

[0045] As further shown in FIGS. 1 to 3 , the folding locking mechanism 200 further includes a fourth mounting seat 6, a fifth mounting seat 8, a second locking component 5, a third locking component 7, a second resilient component 10, and a third resilient component 11. The fourth mounting seat 6, the third locking component 7, and the fifth mounting seat 8 are sequentially arranged along the width direction of the folding locking mechanism 200. Taking FIG. 3 as an example, the fourth mounting seat 6, the third locking component 7, and the fifth mounting seat 8 are sequentially arranged along the direction of arrow B shown in FIG. 3 . The fourth mounting seat 6 is adjacent to the third mounting seat 4 on the side away from the second mounting seat 2. The fourth mounting seat 6 is pivotally connected to the third mounting seat 4. A chamber is formed between the third mounting seat 4 and the fourth mounting seat 6. The second locking component 5 is at least partially and movably disposed within a chamber between the third mounting seat 4 and the fourth mounting seat 6. The second locking component 5 is movable between a second unlocked position and a second locked position along the axial direction of the pivot axes of the third mounting seat 4 and the fourth mounting seat 6. When disposed in the second locked position, the second locking component 5 can lock relative pivotal movement between the third mounting seat 4 and the fourth mounting seat 6, i.e., when disposed in the second locked position, the second locking component 5 can inhibit relative pivotal movement between the third mounting seat 4 and the fourth mounting seat 6. The second locking component 5, when positioned in the second unlocked position, can unlock the relative pivotal movement between the third mounting seat 4 and the fourth mounting seat 6. That is, when the second locking component 5 is positioned in the second unlocked position, the second locking component 5 can allow the relative pivotal movement between the third mounting seat 4 and the fourth mounting seat 6. The second elastic component 10 can provide an elastic force to drive the second locking component 5 to move toward the second locked position. Preferably, in this embodiment, the second elastic component 10 may be a compression spring. However, the present invention is not limited to this embodiment. Furthermore, the second locking component 5 abuts against the first locking component 3.When the first lock component 3 moves from the first lock position to the first release position, the first lock component 3 drives the second lock component 5 to move from the second lock position to the second release position.

[0046] The fifth mounting seat 8 is adjacent to the fourth mounting seat 6 on a side thereof away from the third mounting seat 4. The fifth mounting seat 8 is pivotally connected to the fourth mounting seat 6. A chamber is formed between the fourth mounting seat 6 and the fifth mounting seat 8. The third locking component 7 is at least partially and movably disposed within the chamber between the fourth mounting seat 6 and the fifth mounting seat 8. The third locking component 7 is movable between a third unlocked position and a third locked position along the axial direction of the pivot axes of the fourth mounting seat 6 and the fifth mounting seat 8. When the third locking component 7 is disposed in the third locked position, it can lock the relative pivotal movement between the fourth mounting seat 6 and the fifth mounting seat 8. That is, when the third locking component 7 is disposed in the third locked position, the third locking component 7 can inhibit the relative pivotal movement between the fourth mounting seat 6 and the fifth mounting seat 8. The third lock component 7, when positioned in the third unlocked position, can unlock the relative pivotal movement between the fourth mounting seat 6 and the fifth mounting seat 8. That is, when the third lock component 7 is positioned in the third unlocked position, the third lock component 7 can allow the relative pivotal movement between the fourth mounting seat 6 and the fifth mounting seat 8. The third elastic component 11 can provide an elastic force to drive the third lock component 7 to move toward the third locked position. Preferably, in this embodiment, the third elastic component 11 may be a compression spring. However, the present invention is not limited to this embodiment. Furthermore, the third lock component 7 abuts against the second lock component 5. When the second lock component 5 moves from the second locked position to the second unlocked position, the second lock component 5 drives the third lock component 7 to move from the third locked position to the third unlocked position. In other words, in this embodiment, the relative pivotal movement between the first mounting seat 1 and the second mounting seat 2 can unlock the relative pivotal movement between the second mounting seat 2 and the third mounting seat 4, the relative pivotal movement between the third mounting seat 4 and the fourth mounting seat 6, and the relative pivotal movement between the fourth mounting seat 6 and the fifth mounting seat 8. Therefore, the present invention can provide operational convenience.

[0047] Specifically, as shown in FIGS. 1 to 3 , the frame body 400 includes a backrest 12, a seat 13, rear legs 14, front legs 15, and a handle 16, which are formed by different rods. The backrest 12 is connected to the first mounting seat 1. The seat 13 is connected to the second mounting seat 2. The rear legs 14 are connected to the third mounting seat 4. The front legs 15 are connected to the fourth mounting seat 6. The handle 16 is connected to the fifth mounting seat 8. The backrest 12 and the seat 13 can be pivotally folded or unfolded relative to each other by relative pivotal movement between the first mounting seat 1 and the second mounting seat 2. The seat 13 and the rear legs 14 can be pivotally folded or unfolded relative to each other by relative pivotal movement between the second mounting seat 2 and the third mounting seat 4. The rear legs 14 and the front legs 15 can be pivotally folded or unfolded relative to each other by relative pivotal movement between the third mounting seat 4 and the fourth mounting seat 6. The front legs 15 and the handle 16 can be pivotally folded or unfolded relative to each other by relative pivotal movement between the fourth mounting seat 6 and the fifth mounting seat 8. During the folding operation of the frame main body 400, the relative pivotal movement between the backrest 12 and the seat 13 can unlock the relative pivotal movement between the seat 13 and the rear legs 14, the relative pivotal movement between the rear legs 14 and the front legs 15, and the relative pivotal movement between the front legs 15 and the handle 16 to simultaneously enable the relative pivotal movement between the seat 13 and the rear legs 14, the relative pivotal movement between the rear legs 14 and the front legs 15, and the relative pivotal movement between the front legs 15 and the handle 16. On the other hand, when the frame body 400 is unfolded, the relative pivotal movement between the backrest 12 and the seat 13 can be locked to restrict the relative pivotal movement between the seat 13 and the rear legs 14, the relative pivotal movement between the rear legs 14 and the front legs 15, and the relative pivotal movement between the front legs 15 and the handle 16. Therefore, the present invention has the advantages of a simple structure and easy operation.Furthermore, the folding locking mechanism 200 preferably further includes a release operation component 17 disposed on the upper part of the backrest 12 for unlocking the relative pivotal movement between the backrest 12 and the seat 13. Therefore, the user can unlock all the rods of the frame body 400 without bending their waist.

[0048] More specifically, please refer to FIGS. 6 to 8. FIGS. 6 and 7 are partially exploded views of a child carrier 100 according to a first embodiment of the present invention. FIG. 8 is a partial view of a first mounting seat 1 according to the first embodiment of the present invention. As shown in FIGS. 6 to 8, the driving component 1a includes two pressing portions disposed on the first mounting seat 1. The two pressing portions are symmetrical to each other with respect to the pivot axes of the first mounting seat 1 and the second mounting seat 2. Each of the two pressing portions protrudes from the first mounting seat 1 toward the second mounting seat 2. The first locking component 3 includes two pressed portions 31 extending toward the two pressing portions. When the first mounting seat 1 and the second mounting seat 2 are pivotally folded relative to each other, each of the two pressing portions presses the corresponding pressed portion 31 to drive the first locking component 3 to move from the first locked position to the first unlocked position. Preferably, each of the two pressing portions may be a pressing inclined surface, and each of the two pressed portions 31 may be a protrusion cooperating with the corresponding pressing inclined surface. Each of the two pressing inclined surfaces may press the corresponding protrusion with a height difference. More preferably, each of the two pressing inclined surfaces may be spiral, and the central axis of each of the two pressing inclined surfaces may coincide with the pivot axis of the first mounting seat 1 and the second mounting seat 2. Alternatively, each of the two protrusions may be cylindrical. However, the structures of the drive component and the first lock component are not limited to this embodiment. Two through holes 21 are formed in the second mounting seat 4 and are arranged at positions corresponding to the two pressed portions 31, respectively. Each of the two pressed portions 31 slidably passes through a corresponding through hole 21 to allow the first locking component 3 to extend into the chamber between the first mounting seat 1 and the second mounting seat 2, thereby achieving the purpose of driving the first locking component 3 by the driving component 1a when the first mounting seat 1 and the second mounting seat 2 pivot relative to each other. In this embodiment, the driving component 1a includes two pressing portions symmetrical to each other with respect to the pivot axis of the first mounting seat 1 and the second mounting seat 2, and the first locking component 3 includes two pressed portions 31.Therefore, the driving component 1a can stably press the first locking component 3 to ensure smooth movement of the first locking component 3. However, the number of pressing portions and pressed portions is not limited to this embodiment. For example, in another embodiment, the driving component may include only one pressing portion, and the first locking component may include only one pressed portion.

[0049] 6 to 8, the first locking component 3 further includes a first engaging tooth 32. The second mounting seat 2 includes a first left engaged tooth 22 that cooperates with the first engaging tooth 32. The third mounting seat 4 includes a first right engaged tooth 41 that cooperates with the first engaging tooth 32. When the first locking component 3 is disposed in the first locked position, the first engaging tooth 32 engages with the first left engaged tooth 22 and the first right engaged tooth 41, thereby restricting relative pivotal movement between the second mounting seat 2 and the third mounting seat 4. Since the relative pivotal movement between the second mounting seat 2 and the third mounting seat 4 is restricted at this time, the relative pivotal movement between the seat portion 13 and the rear leg portion 14 is also restricted. When the first locking component 3 is placed in the first release position, the first engaging tooth 32 engages with the first right engaged tooth 41 but disengages from the first left engaged tooth 22 to allow relative pivotal movement between the second mounting seat 2 and the third mounting seat 4. At this time, relative pivotal movement between the second mounting seat 2 and the third mounting seat 4 is allowed, and therefore relative pivotal movement between the seat portion 13 and the rear leg portion 14 is also allowed.

[0050] As shown in FIGS. 3 and 6 to 8 , the first lock component 3 includes a first abutment portion 33 extending toward the second lock component 5. The first abutment portion 33 passes through the third mounting seat 4 and abuts against the second lock component 5. Specifically, the first abutment portion 33 may be a protruding block extending toward the second lock component 5. Preferably, in this embodiment, the cross section of the first lock component 3 may be formed in the shape of two L-shaped structures back to back. However, the present invention is not limited to this embodiment. A through hole 42 is formed in the third mounting seat 4 and is positioned at a position corresponding to the first abutment portion 33. The first abutment portion 33 slidably passes through the through hole 42 and elastically abuts against the second lock component 5.

[0051] As shown in FIGS. 3 and 6 to 8 , the second locking component 5 includes a second engagement tooth 51. The third mounting seat 4 includes a second left engaged tooth 43 that cooperates with the second engagement tooth 51. The fourth mounting seat 6 includes a second right engaged tooth 61 that cooperates with the second engagement tooth 51. When the second locking component 5 is disposed in the second locking position, the second engagement tooth 51 engages with the second left engaged tooth 43 and the second right engaged tooth 61, thereby restricting relative pivotal movement between the third mounting seat 4 and the fourth mounting seat 6. Since the relative pivotal movement between the third mounting seat 4 and the fourth mounting seat 6 is restricted, the relative pivotal movement between the rear leg 14 and the front leg 15 is also restricted. When the second locking component 5 is placed in the second release position, the second engaging tooth 51 engages with the second right engaged tooth 61 but disengages from the second left engaged tooth 43 to allow relative pivotal movement between the third mounting seat 4 and the fourth mounting seat 6. At this time, relative pivotal movement between the third mounting seat 4 and the fourth mounting seat 6 is allowed, and therefore relative pivotal movement between the rear leg 14 and the front leg 15 is also allowed.

[0052] As shown in FIGS. 1 to 3 , the third lock component 7 includes a second abutment portion 52 extending toward the third lock component 7. The second abutment portion 52 passes through the fourth mounting seat 6 and abuts against the third lock component 7. Specifically, the second abutment portion 52 may be a protruding block extending toward the third lock component 7. Preferably, in this embodiment, the cross section of the third lock component 7 may be formed in the shape of two L-shaped structures back to back. However, the present invention is not limited to this embodiment. A through hole 62 is formed in the fourth mounting seat 6 and is positioned at a position corresponding to the second abutment portion 52. The second abutment portion 52 slidably passes through the through hole 62 and elastically abuts against the third lock component 7.

[0053] As shown in FIGS. 3 and 6 to 8 , the third locking component 7 includes a third engagement tooth 71. The fourth mounting seat 6 includes a third left engaged tooth 63 that cooperates with the third engagement tooth 71. The fifth mounting seat 8 includes a third right engaged tooth 81 that cooperates with the third engagement tooth 71. When the third locking component 7 is disposed in the first locked position, the third engagement tooth 71 engages with the third left engaged tooth 63 and the third right engaged tooth 81, thereby restricting relative pivotal movement between the fourth mounting seat 6 and the fifth mounting seat 8. Since the relative pivotal movement between the fourth mounting seat 6 and the fifth mounting seat 8 is restricted, the relative pivotal movement between the front leg 15 and the handle 16 is also restricted. When the third locking component 7 is placed in the first release position, the third engaging tooth 71 engages with the third right engaged tooth 81 but disengages from the third left engaged tooth 63 to allow relative pivotal movement between the fourth mounting seat 6 and the fifth mounting seat 8. At this time, relative pivotal movement between the fourth mounting seat 6 and the fifth mounting seat 8 is allowed, and therefore relative pivotal movement between the front leg 15 and the handle 16 is also allowed.

[0054] Please refer to Figures 6 and 9 to 14. Figure 9 is a partial internal structural view of the child carrier 100 according to the first embodiment of the present invention. Figure 10 is an enlarged view of section D of the child carrier 100 shown in Figure 9 according to the first embodiment of the present invention. Figure 11 is another partial internal structural view of the child carrier 100 according to the first embodiment of the present invention. Figure 12 is an enlarged view of section E of the child carrier 100 shown in Figure 11 according to the first embodiment of the present invention. Figure 13 is a partial view of the child carrier 100 when the limiting component 181 according to the first embodiment of the present invention extends into the limiting slot 1b. Figure 14 is an enlarged view of section F of the child carrier 100 shown in Figure 13 according to the first embodiment of the present invention. As shown in Figures 6 and 9 to 14, the folding locking mechanism 200 further includes a limiting assembly 18 configured to limit the relative pivot angle between the first mounting seat 1 and the second mounting seat 2. The limiting assembly 18 includes a limiting component 181, a fourth elastic component 182, and a limiting connection component 183. The limiting component 181 is installed on the second mounting seat 2 and protrudes toward the first mounting seat 1. A limiting slot 1b is formed in the first mounting seat 1 and disposed at a position corresponding to the limiting component 181. The limiting component 181 slidably extends into the limiting slot 1b. Through cooperation between the limiting component 181 and the limiting slot 1b, the limiting assembly 18 can limit the relative pivot angle between the first mounting seat 1 and the second mounting seat 2 to prevent excessive relative pivot angle between the first mounting seat 1 and the second mounting seat 2. For example, the limiting component 181 may be configured to slidably extend into the limiting slot 1b when the child carrier 100 is in the folded state to prevent excessive folding of the child carrier 100. Specifically, the limiting connection component 183 is locked to the second mounting seat 2. Both ends of the fourth elastic component 182 may be connected to the limiting connection component 183 and the limiting component 181, respectively. The limiting component 181 is installed on the second mounting seat 2 by the fourth elastic component 182 and the limiting connection component 183, so that the limiting component 181 may elastically abut against the limiting slot 1b to prevent wear or damage to the component due to a collision.Preferably, in this embodiment, the restricting component 181 may be cylindrical to achieve smooth sliding movement of the restricting component 181. However, the present invention is not limited to this embodiment. Furthermore, a through hole 23 is formed in the second mounting seat 2 and arranged at a position corresponding to the restricting component 181. The restricting component 181 slidably passes through the through hole 23 and elastically abuts against the restricting slot 1b.

[0055] 1 to 14, the operating principle of the folding locking mechanism 200 is as follows: When folding the frame body 400 of the child carrier 100, the user presses the release operating component 17 to unlock the relative pivotal movement of the backrest 12 and the seat 13, and then operates the backrest 12 to drive the backrest 12 to pivotally fold relative to the seat 13 along the direction of arrow A shown in FIG. 1, and drive the first mounting seat 1 to pivotally fold relative to the second mounting seat 2 along the direction of arrow A. When the first mounting seat 1 is pivotally folded relative to the second mounting seat 2 along the direction of the arrow A, the pressing portion of the driving component 1a presses the pressed portion 31 of the first locking component 3 to drive the first locking component 3 and move it from the first locked position to the first released position along the direction of the arrow B shown in FIG. 3 by overcoming the elastic force generated by the first elastic component 9. Because the first locking component 3 abuts against the second locking component 5 and the second locking component 5 abuts against the third locking component 7, the second locking component 5 and the third locking component 7 are driven to move from the second locking position and the third locking position to the second unlocking position and the third unlocking position, respectively, and when the first locking component 3 moves from the first locking position to the first unlocking position, the relative pivoting movement between the seat 13 and the rear legs 14, the relative pivoting movement between the rear legs 14 and the front legs 15, and the relative pivoting movement between the front legs 15 and the handle 16 can be unlocked. The user can then operate the seat 13, rear legs 14, front legs 15 and handle 16 to complete the folding operation of the frame body 400 of the child carrier 100 by relative pivoting movement between the seat 13 and rear legs 14, relative pivoting movement between the rear legs 14 and front legs 15, and relative pivoting movement between the front legs 15 and handle 16.

[0056] On the other hand, when unfolding the frame body 400 of the child carrier 100, the user can operate the backrest 12 to drive the backrest 12 to pivotally unfold relative to the seat 13 along the direction opposite to the arrow direction A, and can drive the first mounting seat 1 to pivotally unfold relative to the second mounting seat 2 along the direction opposite to the arrow direction A. When the first mounting seat 1 pivotally unfolds relative to the second mounting seat 2 along the direction opposite to the arrow direction A, the pressing portion of the driving component 1 a does not press the pressed portion 31 of the first locking component 3 along the arrow direction B. Therefore, the elastically deformed first elastic component 9 can drive the first locking component 3 to move from the first unlocked position to the first locked position along the direction opposite to the arrow direction B. When the first locking component 3 moves from the first unlocked position to the first locked position, the first locking component 3 does not press the second locking component 5 along the direction of arrow B. Therefore, the elastically deformed second elastic component 10 can drive the second locking component 5 to move from the second unlocked position to the second locked position along the direction opposite to the direction of arrow B. When the second locking component 5 moves from the second unlocked position to the second locked position, the second locking component 5 does not press the third locking component 7 along the direction of arrow B. Therefore, the elastically deformed third elastic component 11 can drive the third locking component 7 to move from the third unlocked position to the third locked position along the direction opposite to the direction of arrow B. The first locking component 3 arranged in the first locking position, the second locking component 5 arranged in the second locking position, and the third locking component 7 arranged in the third locking position, respectively, lock the relative pivoting movement between the seat 13 and the rear legs 14, the relative pivoting movement between the rear legs 14 and the front legs 15, and the relative pivoting movement between the front legs 15 and the handle 16, thereby allowing the frame body 400 to be locked in the unfolded state.

[0057] Please further refer to Figures 15 to 26. Figure 15 is a schematic diagram of a child carrier 500 in an unfolded state according to the second embodiment of the present invention.

Figure 23 is a partial cross-sectional view of the child carrier 500 according to the second embodiment of the present invention. Figure 24 is an enlarged view of a portion J of the child carrier 500 according to the second embodiment of the present invention. Figure 25 is a view of a driven component 20 according to the second embodiment of the present invention. FIG. 26 is a diagram of a pressing component 19 according to a second embodiment of the present invention. As shown in FIGS. 15 to 26, a child carrier 500 includes two folding locking mechanisms 300 and a frame main body 400. The structure of the folding locking mechanism 300 of this embodiment is similar to that of the folding locking mechanism 200 of the first embodiment. Unlike the first embodiment, the folding locking mechanism 300 of this embodiment further includes a shell 202 configured to accommodate a fourth mounting seat, a fifth mounting seat, and a third locking component. The third mounting seat 4 can be detached from the fourth mounting seat. FIGS. 15 to 26 show only a portion of the structure of the folding locking mechanism 300, without showing the fourth mounting seat, the fifth mounting seat, the second locking component, the third locking component, and the limiting assembly. The structures of the fourth mounting seat, the fifth mounting seat, the second locking component, the third locking component, and the limiting assembly of this embodiment are similar to the structures of the fourth mounting seat 6, the fifth mounting seat 8, the second locking component 5, the third locking component 7, and the limiting assembly 18 of the first embodiment, and detailed descriptions thereof will be omitted here for simplicity.

[0058] Furthermore, each of the two folding locking mechanisms 300 of this embodiment includes a driving component 2a. The driving component 2a includes a pressing component 19, a driven component 20, and a connecting component 201. The pressing component 19 is pivotally connected to the first mounting seat 1. The pivot axis of the pressing component 19 coincides with the pivot axes of the first mounting seat 1 and the second mounting seat 2. The driven component 20 is movably disposed between the pressing component 19 and the third locking component 3 and is movable between an extended position and a retracted position. Preferably, the pivot axis of the pressing component 19 passes through the center of the driven component 20. The driven component 20 is movable along the axial direction of the pivot axes of the first mounting seat 1 and the second mounting seat 2. The connecting component 201 is connected to the pressing component 19, whereby the pressing component 19 is driven by the connecting component 201 to pivot relative to the first mounting seat 1 in order to drive the first locking component 3 to move from the first locked position to the first released position, and can drive the driven component 20 to move from the retracted position to the extended position. As can be seen, in this embodiment, the two folding locking mechanisms 300 are symmetrically arranged on two sides of the frame body 400. The two connecting components 201 connected to the two pressing components 19 can be connected to each other to form an integral connecting structure connected to the two pressing components 19.

[0059] As shown in FIGS. 17 to 26 , the pressing component 19 includes three adjacent portions 191 arranged adjacently and extending toward the driven component 20. The driven component 20 includes two adjacent portions 20a arranged adjacently to the three adjacent portions 191 and cooperating with each other. Each of the three adjacent portions 191 presses the corresponding adjacent portion 20a to drive the driven component 20 to move from the retracted position to the extended position, thereby achieving the purpose of driving the driven component 20 to move by the pressing component 19. Each of the three adjacent portions 191 may be an adjacent protrusion. Each of the two adjacent portions 20a may be an adjacent protrusion. When the driven component 20 is arranged in the retracted position, the two adjacent protrusions and the three adjacent protrusions are offset from each other, i.e., each of the two adjacent protrusions is arranged in a recess between two corresponding adjacent portions 191. When the driven component 20 is disposed in the extended position, the two adjacent protrusions and the two corresponding adjacent protrusions are aligned and abut against each other. In other words, when the pressing component 19 pivots relative to the first mounting seat 1 to drive the two adjacent protrusions and the two corresponding adjacent protrusions to align and abut against each other, the driven component 20 can be driven by the pressing component 19 to move from the retracted position to the extended position. When the pressing component 19 pivots relative to the first mounting seat 1 to drive each of the two adjacent protrusions to move within the recesses between the two corresponding adjacent portions 191, the pressing component 19 does not press the driven component 20, thereby allowing the driven component 20 to be driven by the first locking component 3 to move from the extended position to the retracted position. Preferably, each of the three adjacent protrusions and each of the two adjacent protrusions may have an arc-shaped structure. However, the number of adjacent portions and adjacent portions is not limited to this embodiment. For example, in another embodiment, the pushing component may include only one abutment and the driven component may include only one abutment.

[0060] As shown in FIGS. 17 to 26 , the driven component 20 includes two pressing abutments 20b arranged in opposite directions and extending toward the first locking component 3. The first locking component 3 includes two pressed portions 31 each extending toward the two pressing abutments 20b. When the driven component 20 moves from the retracted position to the extended position, the two pressing abutments 20b press the two pressed portions 31 to drive the first locking component 3 and move it from the first locked position to the first unlocked position. However, the number of pressing abutments and pressed portions is not limited to this embodiment. In another embodiment, the driven component may include only one pressing abutment, and the first locking component may include only one pressed portion.

[0061] 15 to 26, the operating principle of the folding locking mechanism 300 is as follows: when folding the frame body 400 of the child carrier 500, the user presses the release operation component 17 to unlock the relative pivotal movement of the backrest 12 and the seat 13, and then operates the connecting component 20 to drive the pressing component 19 to pivot relative to the first mounting seat 1, and drive the adjacent portion 191 of the pressing component 19 to press the adjacent portion 20a of the driven component 20, which drives the first locking component 3 to move from the retracted position to the extended position to move from the first locked position to the first unlocked position. As in the first embodiment, the first locking component 3 abuts against the second locking component, which in turn abuts against the third locking component, so that when the first locking component 3 moves from the first locking position to the first unlocked position, the second locking component and the third locking component can be driven and moved to the second unlocked position and the third unlocked position, respectively, to unlock the relative pivoting movement between the seat 13 and the rear legs 14, the relative pivoting movement between the rear legs 14 and the front legs 15, and the relative pivoting movement between the front legs 15 and the handle 16. Thereafter, the user can complete the folding operation of the frame body 400 of the child carrier 500 by operating the seat portion 13, the rear legs 14, the front legs 15, and the handle 16 to perform relative pivoting movements between the seat portion 13 and the rear legs 14, between the rear legs 14 and the front legs 15, and between the front legs 15 and the handle 16. When unfolding the frame body 400 of the child carrier 500, the unfolding operation of the frame body 400 can be completed by reversing the folding operation.

[0062] In summary, in this invention, when the first mounting seat, second mounting seat, and third mounting seat of the folding locking mechanism are connected to different rods of the frame body, the folding locking mechanism can use the drive component to move the first locking component to a first release position to simultaneously enable relative pivotal movement between the first mounting seat and the second mounting seat, and relative pivotal movement between the second mounting seat and the third mounting seat, thereby enabling relative movement of the different rods simultaneously and achieving the folding operation of the entire frame body. Therefore, this invention has the advantages of being simple in structure and easy to operate.
