[0024] As shown in FIG. 1, an embodiment of the present invention provides a child-carrying device, such as a baby stroller for children, including a folding carrier 10 and a carrier frame 20. The folding carrier 10 can be detachably or non-detachably attached to the carrier frame 20. Of course, in other embodiments, the child-carrying device may be a high chair, a children's dining chair, or the like. The folding carrier 10 and the armrest support rod 200 of the child-carrying device can be folded together with the folding of the backrest support rod 300, which is convenient to use.

[0025] Specifically, as shown in FIGS. 1, 13, and 14, the folding carrier 10 includes a seat assembly 100, an armrest support rod 200, a backrest support rod 300, a locking mechanism 400, a link mechanism 500, an armrest body 600, and a backrest body 700. The seat assembly 100 includes a seat body 110, two side plates 120, and two side covers 130. The seat body 110 is for placing a child. The two side plates 120 are respectively connected to two opposite sides of the seat body 110, that is, the left side and the right side of the seat body 110. In this embodiment, the seat body 110 and the two side plates 120 are integrally formed. Of course, in other embodiments, the seat body 110 and the two side plates 120 may be independent components from each other. The two side covers 130 respectively cover the side portions of the two side plates 120 on the side opposite to the seat body 110, that is, the outer sides of the two side plates 120, and respectively form mounting spaces. On the left and right sides of the seat body 110, further, an armrest support rod 200, a backrest support rod 300, a locking mechanism 400, and a link mechanism 500 are respectively provided. Both ends of the armrest body 600 are respectively detachably connected to the armrest support rods 200 arranged on both sides of the seat body 110, and both ends of the backrest body 700 are respectively connected to the backrest support rods 300 arranged on both sides of the seat body 110.

[0026] Hereinafter, taking the side plate 120, the armrest support rod 200, the backrest support rod 300, the locking mechanism 400, and the link mechanism 500 arranged on one side of the seat body 110 as examples, the configuration of the folding carrier 10 will be specifically described.

[0027] As shown in FIG. 2, the armrest support rod 200 is pivotally connected to the side plate 120 at the first pivot point M, and the backrest support rod 300 is pivotally connected to the side plate 120 at the second pivot point N via a drive member 510 (details will be described later). In this embodiment, both the armrest support rod 200 and the backrest support rod 300 are disposed on the side facing the seat body 110 of the side plate 120, that is, inside the side plate 120. As shown in FIGS. 3 to 5, both the armrest support rod 200 and the backrest support rod 300 have a deployed position and a folded position. When the armrest support rod 200 and the backrest support rod 300 are in the deployed position, the folding carrier 10 can seat a child. When the armrest support rod 200 and the backrest support rod 300 are in the folded position, the folding carrier 10 can be stored. The lock mechanism 400 and the link mechanism 500 are both disposed on the side plate 120 and are disposed between the armrest support rod 200 and the backrest support rod 300. The lock mechanism 400 is configured to lock the armrest support rod 200 in the deployed position with respect to the side plate 120. The backrest support rod 300 is folded in a direction approaching the armrest support rod 200, whereby the link mechanism 500 moves and the lock of the lock mechanism 400 is released, and the armrest support rod 200 can be rotated to a folded position with respect to the side plate 120 (details will be described later).

[0028] Specifically, as shown in FIGS. 12 to 14, the lock mechanism 400 is disposed in the mounting space. That is, the lock mechanism 400 is disposed on the side opposite to the seat body 110 of the side plate 120, that is, outside the side plate 120. The lock mechanism 400 includes a lock member 410, a lock pin 420, a first reset member 430, and a second reset member 440.

[0029] Also, as shown in FIGS. 12 to 14, the lock member 410 is disposed on the side plate 120 and includes a rotating portion 411 and a lock portion 412 connected to the rotating portion 411. As shown in FIGS. 19 and 20, two sector-shaped hollow fitting protrusions 411a are provided on the side of the rotating portion 411 facing the side plate 120, and two sector-shaped fitting recesses 210 corresponding to the fitting protrusions 411a are provided at the end of the armrest support rod 200 pivotally connected to the side plate 120. A fitting hole (not shown) may be provided in the side plate 120. The two fitting protrusions 411a penetrate through the fitting hole and are respectively inserted into the two fitting recesses 210, so that the lock member 410 can be fixedly connected to the armrest support rod 200. The lock member 410 and the armrest support rod 200 can rotate synchronously. As shown in FIGS. 12 and 13, when the armrest support rod 200 is in the deployed position, the lock member 410 is in the first position. As shown in FIGS. 17 and 18, when the armrest support rod 200 is in the folded position, the lock member 410 is in the second position. Of course, in other embodiments, another type of first fitting portion may be provided on the rotating portion 411, and a second fitting portion corresponding to the first fitting portion may be provided on the armrest support rod 200. The first fitting portion or the second fitting portion penetrates through the side plate 120 and fits with the second fitting portion or the first fitting portion. Alternatively, the lock member 410 and the armrest support rod 200 may be fixedly connected via a fastener such as a rivet.

[0030] As shown in FIGS. 13 and 20, the lock portion 412 includes a first side portion 412a and a second side portion 412b opposite to the first side portion 412a, and a lock groove 412c is provided in the first side portion 412a. Further, a restricting member 121 and a restricting protrusion 122 are provided on the side plate 120. When the locking member 410 is in the first position, the second side portion 412b abuts against the restricting member 121. When the locking member 410 is in the second position, the first side portion 412a abuts against the restricting protrusion 122. In this embodiment, both the first side portion 412a and the second side portion 412b have a zigzag structure. The restricting protrusion 122 and the restricting member 121 each have a zigzag structure. The zigzag structures of the restricting protrusion 122 and the restricting member 121 fit with the first side portion 412a and the second side portion 412b. In this way, the rotation angle of the locking member 410 can be restricted within an appropriate range, that is, the rotation angle of the armrest support rod 200 can be restricted within an appropriate range. Therefore, when the armrest body 600 connected to the armrest support rod 200 is in the deployed position (as shown in FIG. 3), depending on the deployment angle, a caregiver can support a child sitting on the seat body 110. When the armrest body 600 is in the folded position (as shown in FIG. 5), depending on the folding angle, the backrest support rod 300 can be folded to a convenient position for the user to store the folding carrier 10. In this embodiment, the locking member 410 is integrally formed. Of course, in other embodiments, the locking member 410 may be formed by connecting the rotating portion 411 and the locking portion 412 independently of each other.

[0031] Also, as shown in FIG. 13, the lock pin 420 is movably disposed on the side plate 120 and can be inserted into the lock groove 412c. Specifically, a slide groove 123 extending obliquely toward the locking member 410 is provided on the side plate 120, and the lock pin 420 is slidably disposed in the slide groove 123.

[0032] Furthermore, as shown in FIG. 13, one end of the first reset member 430 abuts against the end of the lock pin 420 away from the lock member 410, and the other end of the first reset member 430 abuts against the side plate 120. Specifically, it abuts against the abutting projection 124 of the side plate 120. The first reset member 430 and the lock pin 420 can be disposed in the lock slide groove 123. The first reset member 430 biases the lock pin 420 so that the lock pin 420 can always move in a direction approaching the lock member 410. In this embodiment, the first reset member 430 is a spring.

[0033] Furthermore, as shown in FIG. 13, one end of the second reset member 440 is connected to the second side portion 412b, and the other end of the second reset member 440 is connected to the side plate 120. The second reset member 440 always enables the lock member 410 to rotate toward the first position. In this embodiment, the second reset member 440 is a tension spring. A first fixing hole 412d is provided in the second side portion 412b, and a second fixing post 125 is provided in the side plate 120. The two connection rings at both ends of the tension spring are fixed to the first fixing hole 412d and the second fixing post 125, respectively. However, the present invention is not limited thereto. In a modified embodiment of this embodiment, a fixing post is provided in the second side portion 412b, and the two connection rings at both ends of the tension spring are sleeved on the fixing post of the second side portion 412b and the second fixing post 125, respectively.

[0034] Specifically, as shown in FIGS. 6, 7, 13, and 14, the link mechanism 500 includes a drive member 510, a transmission member 520, a traction member 530, and a take-up post 540. The drive member 510 is disposed inside the side plate 120. The transmission member 520 penetrates the side plate 120. Both the traction member 530 and the take-up post 540 are disposed outside the side plate 120, that is, in the mounting space. The drive member 510 has a generally triangular plate-like structure, and one side of the drive member 510 is fixedly connected to the backrest support rod 300 in a non-movable state with respect to the backrest support rod 300. The corner of the drive member 510 opposite to the backrest support rod 300 is pivotally connected to the side plate 120 at the second pivot point N and has an arcuate edge portion 511 that abuts against the transmission member 520. The outer contour of the arcuate edge portion 511 is designed such that as the backrest support rod 300 pivots and folds in the direction F1 approaching the armrest support rod 200, the distance from the contact point of the outer contour with respect to the transmission member 520 to the second pivot point N gradually increases. That is, the distance from the contact point of the arcuate edge portion 511 with respect to the transmission member 520 to the second pivot point N gradually increases generally in the direction opposite to the direction F1. The drive member 510 is further provided with a positioning portion 512. The side plate 120 is provided with a plurality of positioning holes 126. When the backrest support rod 300 is rotated in a direction approaching or moving away from the armrest body 600, the positioning portion 512 is selectively inserted into one of the positioning holes 126, and the inclination angle of the backrest support rod 300 can be adjusted.

[0035] Also, as shown in FIGS. 7, 9, 13, and 14, the transmission member 520 has a generally columnar structure. The side plate 120 is provided with elongated holes 127 arranged in a substantially horizontal direction (i.e., direction F2), and the transmission member 520 can pass through the elongated holes 127 and move along the elongated holes 127. Thereby, one end of the transmission member 520 arranged inside the side plate 120 can abut against the arc-shaped edge portion 511 of the driving member 510, and the other end of the transmission member 520 arranged outside the side plate 120 can be connected to the traction member 530. When the backrest support rod 300 is folded in the direction F1 approaching the armrest support rod 200, the arc-shaped edge portion 511 pushes the transmission member 520 to move in the direction F2 within the elongated hole 127.

[0036] Also, as shown in FIGS. 12 and 13, the take-up post 540 is disposed on the side away from the lock pin 420 of the transmission member 520. That is, the transmission member 520 is disposed in the direction F2 with respect to the take-up post 540. In other words, the transmission member 520 is disposed approximately between the lock pin 420 and the take-up post 540. In this embodiment, the take-up post 540 may be the rotation axis of the drive member 510 disposed at the second pivot point N, so that the processing procedure can be reduced. In this embodiment, the traction member 530 is a steel wire. Of course, in other embodiments, the traction member 530 may be another rope that can pull and slide the lock pin 420. One end of the traction member 530 is connected to the transmission member 520, and the other end of the traction member 530 is wound around the take-up post 540 and connected to the lock pin 420. In this way, the transmission member 520, the traction member 530, the take-up post 540, and the lock pin 420 form a structure capable of changing the moving direction of the traction member 530, and the transmission member 520 can drive the lock pin 420 to move in a position opposite to the moving direction of the transmission member 520 or in an intersecting direction via the traction member 530. For example, as shown in FIGS. 15 and 16, when the backrest support rod 300 is folded in the direction of F1 and in the direction approaching the armrest support rod 200, the arcuate edge 511 pushes the transmission member 520 to move in the direction of F2 and in the direction approaching the lock member 410. At the same time, the transmission member 520 applies a force in the direction opposite to the direction of F2 to the lock pin 420 via the traction member 530, and the lock pin 420 moves in the direction of F3, that is, in the direction away from the lock member 410, under the restriction of the slide groove 123. When the lock pin 420 disengages from the lock groove 412c, as shown in FIGS. 17 and 18, the lock of the lock mechanism 400 is released.

[0037] The specific operating principle of the folding carrier 10 is as follows.

[0038] As shown in FIGS. 12 and 13, when the armrest support rod 200 and the backrest support rod 300 are in the deployed state, the lock pin 420 is inserted into and locked in the lock groove 412c. In this case, when it is necessary to fold the folding carrier 10, as shown in FIGS. 15 and 16, the backrest support rod 300 is pushed down in a direction approaching the armrest support rod 200 (i.e., direction F1). At the same time, the backrest support rod 300 rotationally drives the drive member 510 in the F1 direction, the arc-shaped edge 511 of the drive member 510 presses the transmission member 520 in the F2 direction, and at the same time the transmission member 520 pulls the lock pin 420 via the traction member 530. As a result, the lock pin 420 in the slide groove 123 moves in the F3 direction and gradually moves away from the lock member 410. When the lock pin 420 moves out of the lock groove 412c, the lock of the lock mechanism 400 is released, and the lock member 410 and the armrest support rod 200 driven by the lock member 410 become rotatable with respect to the side plate 120. The pushed-down backrest support rod 300 presses the armrest body 600 and moves the armrest body 600 and the armrest support rod 200 in a direction approaching the seat body 110 until the folding is completed. In this case, as shown in FIGS. 17 and 18, the drive member 510 is disposed at the second position, the first reset member 430 is compressed, the second reset member 440 is extended, and the first side portion 412a of the lock member 410 abuts against the limiting protrusion 122.

[0039] If it is necessary to expand the foldable carrier 10 in the folded state for use, as shown in FIGS. 15 and 16, pull the backrest support rod 300 in a direction away from the armrest support rod 200. Then, since the backrest support rod 300 moves the drive member 510 in a direction opposite to the direction F1, the drive member 510 cannot push the transmission member 520 in the direction F2. Then, the transmission member 520 cannot pull the lock pin 420 in the direction F3, and the lock pin 420 moves in a direction opposite to the direction F3 toward the lock member 410 by the elastic force of the first reset member 430. At the same time, the armrest support rod 200 does not apply a pressing force to the armrest body 600, and the lock member 410 rotates toward the first position by the elastic force of the second reset member 440 until the lock groove 412c faces the lock pin 420. Thereafter, the lock pin 420 is inserted into the lock groove 412c, the armrest support rod 200 and the side plate 120 are locked again, and the second side portion 412b of the lock member abuts against the limiting member 121 (see FIGS. 12 and 13).

[0040] Of course, in other embodiments, as long as the link mechanism 500 is driven to move in such a manner that when the backrest support rod 300 is folded in a direction approaching the armrest support rod 200, the lock pin 420 moves in a direction away from the lock member 410, the link mechanism 500 can be configured in another form. For example, in other embodiments, the link mechanism 500 may be an elongated link member (not shown). One end of the link member is pivotally connected to the armrest support rod 200, and the other end of the link member is pivotally connected to the lock pin 420. When the backrest support rod 300 and the armrest support rod 200 are in the deployed position, the end portion of the lock pin 420 on the side away from the link member can be inserted into the lock groove 412c of the lock member 410. When the backrest support rod 300 is folded in a direction approaching the armrest support rod 200, the link member is pivoted together with the backrest support rod 300, and at the same time, the lock pin 420 is driven to move in a direction away from the lock member 410, releasing the lock of the lock mechanism 400, and the armrest support rod 200 is folded together with the backrest support rod 300. Further, a tension spring (not shown) may be disposed between the front end of the seat body 110 and the armrest support rod 200. In a state where the armrest support rod 200 is folded, the tension spring is compressed, and when the backrest support rod 300 is deployed and not pressed against the armrest body 600, the armrest support rod 200 returns to the deployed position by the elastic force of the tension spring.

[0041] The foldable carrier 10 and the child carrier device as described above have at least the following technical effects.

[0042] In the above folding carrier 10, both the armrest support rod 200 and the backrest support rod 300 have a folded position and a deployed position. When it is necessary to fold the folding carrier 10, it is only necessary to fold only the backrest support rod 300 in a direction approaching the armrest support rod 200. As a result, the lock mechanism 400 is unlocked via the link mechanism 500, and the armrest support rod 200 can be rotated with respect to the side plate 120. The armrest support rod 200 can be rotated from the deployed position to the folded position together with the backrest support rod 300, and the entire folding carrier 10 can be folded without disassembling the armrest support rod 200, which is convenient to use.
