[0046] In order to explain the technical content and structural features of the present invention in detail, further description is given below in combination with the implementation modes and the accompanying drawings.

[0047] See also Figures 1 to 5The present invention provides a foldable child carrier 100, comprising a seat portion 50 pivotally connected to a frame and a backrest portion 40 folded relative to the seat portion 50. A locking mechanism 10 is provided between the seat portion 50 and the frame, and the locking mechanism 10 is used to lock the relative position between the seat portion 50 and the frame. The seat portion 50 can be pivotally connected to the frame through a second fixing seat 51, and connected and locked by the locking mechanism 10, so that the seat portion 50 is fixed to the frame. When the locking mechanism 10 is released, the seat portion 50 can rotate along the pivot point between the seat portion 50 and the frame. Specifically, a movable driving member 20 is further provided between the seat portion 50 and the backrest portion 40. During the folding process of the backrest portion 40, the first fixing seat 41 rotates relative to the second fixing seat 51, and at this time, the driving member 20 rotates with the rotation of the first fixing seat 41, that is, the driving member 20 rotates relative to the second fixing seat 51. It is understandable that when the backrest 40 is unfolded relative to the seat 50, or when the backrest 40 is folded, the driver 20 cannot release the locking mechanism 10. When the backrest 40 is folded on the seat 50, the driver 20 can act on the locking mechanism 10, and the movement of the driver 20 causes the locking mechanism 10 to release the seat 50 and the frame, so that the seat 50 can rotate relative to the frame. The foldable child carrier 100 of the present invention is easy to operate and safer to use.

[0048] After adopting the above technical solution, the foldable child carrier 100 of the present invention includes a frame, a seat portion 50, and a backrest portion 40 folded on the seat portion 50. The seat portion 50 is pivotally connected to the frame, and the backrest portion 40 can be folded relative to the seat portion 50. A locking mechanism 10 is also provided between the seat portion 50 and the frame, and a driving member 20 for driving the locking mechanism 10 is also provided between the backrest portion 40 and the seat portion 50. When the backrest portion 40 is in an unfolded state relative to the seat portion 50, the driving member 20 cannot release the locking mechanism 10, and the seat portion 50 cannot rotate relative to the frame. When the backrest portion 40 is in a folded state relative to the seat portion 50, the driving member 20 can act on the locking mechanism 10, and the movement of the driving member 20 can drive the locking mechanism 10 to release, so that the seat portion 50 can rotate relative to the frame. In the foldable child carrier 100 of the present invention, the driving member 20 that drives the locking mechanism 10 can release the locking mechanism 10 only when the backrest portion 40 is in a folded state, which can effectively prevent the child carrier from being misused during use and is safer and more reliable. After the backrest portion 40 of the foldable child carrier 100 of the present invention is folded relative to the seat portion 50, the locking mechanism 10 can be released through the movement of the driving member 20, so that the seat portion 50 and the frame are released, so that the seat portion 50 can be rotated relative to the frame to adjust the relative position between the seat portion 50 and the frame, making the overall volume smaller and easier to carry and store. The foldable child carrier 100 of the present invention has a novel structure, is easy to operate, is safe and reliable, and is easy to carry and store.

[0049] See also Figures 6 to 13 In some optional embodiments, a first fixed seat 41 is connected to the backrest portion 40, and a second fixed seat 51 is connected to the seat portion 50. When the backrest portion 40 is folded, the first fixed seat 41 rotates relative to the second fixed seat 51. The driving member 20 is installed on the first fixed seat 41. When the backrest portion 40 is folded relative to the seat portion 50, the driving member 20 can rotate with the rotation of the first fixed seat 41, that is, the driving member 20 is stationary relative to the first fixed seat 41 during the folding process. Specifically, the driving member 20 is also connected to an operating member 30 for driving the driving member 20. The operating member 30 is connected to the connecting portion 22 of the driving member 20 and is located outside the first fixed seat 41 to facilitate the user's operation. The operating member 30 has a flexible structure. The operating member 30 with a flexible structure is more comfortable and convenient to operate, and the operating member 30 with a flexible structure will not affect the use of the child carrier when not in operation. In this embodiment, when the backrest portion 40 is folded onto the seat portion 50, the driving member 20 rotates with the first fixing seat 41 to a position where it can act on the locking mechanism 10. At this time, the operating member 30 located outside the first fixing seat 41 is pulled to rotate the driving member 20 relative to the first fixing seat 41, so that the driving member 20 can drive the locking mechanism 10 to release the lock.

[0050] See also Figures 6 to 13 In some optional embodiments, the foldable child carrier 100 further includes a positioning member 12 that can be detachably matched with the frame. The positioning member 12 is respectively matched with the second fixing seat 51 and the frame, so that the seat portion 50 and the backrest portion 40 on the seat portion 50 can be detachably installed on the frame. The locking mechanism 10 includes a locking member 11 that is movably arranged on the second fixing seat 51. The locking member 11 cooperates with the positioning member 12 to lock the relative position between the seat portion 50 and the positioning member 12. When the activity of the driving member 20 acts on the locking member 11, the activity of the driving member 20 causes the locking member 11 to disengage from the positioning member 12 to release the lock, so that the seat portion 50 can rotate relative to the frame or the positioning member 12.

[0051] See also Figure 6 and Figure 7 In this embodiment, a locking portion 111 that can extend out of the second fixing seat 51 is provided at one end of the locking member 11 away from the transmission member 13, and a positioning portion 121 that cooperates with the locking portion 111 is provided on the positioning member 12. When the locking portion 111 protrudes out of the second fixing seat 51 and cooperates with the positioning portion 121, the seat portion 50 is locked to the frame. When the driving member 20 and the transmission member 13 are in contact and active, the transmission member 13 can drive the locking portion 111 to retract into the second fixing seat 51 so that the locking portion 111 is disengaged from the positioning portion 121 to release the lock, thereby allowing the seat portion 50 to rotate relative to the frame or the positioning member 12.

[0052] See also Figures 6 to 13In some optional embodiments, a transmission member 13 is further provided between the driving member 20 and the locking member 11, and the driving member 20 acts on the locking member 11 through the transmission member 13. The driving member 20 is rotatably provided on the first fixed seat 41, and the locking member 11 is telescopically and movably installed on the second fixed seat 51. An arc groove 411 for the locking member 11 to pass through is provided on the first fixed seat 41, and the locking member 11 is located at different positions of the arc groove 411 when the first fixed seat 41 rotates relative to the second fixed seat 51. It can be understood that during the folding process of the backrest 40, the driving member 20 rotates with the first fixed seat 41, and the locking member 11 is stationary with the second fixed seat 51. At this time, the driving member 20 rotates relative to the locking member 11. The arc groove 411 that penetrates can prevent the locking member 11 from interfering with the rotation of the first fixed seat 41 and the driving member 20. Specifically, the transmission member 13 is connected to the locking member 11 and is provided on the movement path of the driving member 20. When the driving member 20 rotates to contact the transmission member 13, the operating member 30 is operated to make the driving member 20 rotate relative to the first fixing seat 41 and act on the transmission member 13, so that the transmission member 13 drives the locking member 11 to move. The transmission member 13 is movably arranged between the first fixing seat 41 and the driving member 20, and the transmission member 13 can move along the thickness direction of the first fixing seat 41 and the driving member 20, so as to drive the locking member 11 to perform telescopic movement.

[0053] See also Figures 8 to 14 In some optional embodiments, a driving part that cooperates with the transmission member 13 is provided on the driving member 20, and the transmission member 13 is provided on the movement path of the driving part. Specifically, the driving part is a driving inclined plane 21, and the driving member 20 moves so that the driving inclined plane 21 pushes the transmission member 13, and then the transmission member 13 drives the locking member 11 to move to disengage from the locking position. Among them, a straight portion 211 for the transmission member to stay is provided at one end of the driving inclined plane 21. When the transmission member 13 is pushed to the straight portion 211 by the driving inclined plane 21, the displacement of the locking member 11 is sufficient to disengage from the locking position to release the lock. Since the driving inclined plane 21 is arranged obliquely, the transmission member 13 will have a downward trend on the driving inclined plane 21. The straight portion 211 is provided at the highest point of the driving inclined plane 21, so that the transmission member 13 can be more stably located on the driving inclined plane 21, so that the locking member 11 can be better driven to disengage from the positioning member 12.

[0054] See also Figures 8 to 12In some optional embodiments, a first stopper 412 for limiting the rotation of the driving member 20 in the first direction is provided on the first fixed seat 41, and a first stopper 23 cooperating with the first stopper 412 is provided on the driving member 20. A second stopper 413 for limiting the rotation of the driving member 20 in the second direction is also provided on the first fixed seat 41, and a second stopper 24 cooperating with the second stopper 413 is provided on the driving member 20. The first direction is the direction in which the driving member 20 rotates counterclockwise relative to the first fixed seat 41. The second direction is the direction in which the driving member 20 rotates clockwise relative to the first fixed seat 41. It can be understood that the operating member 30 pulls the driving member 20 to rotate between the first stopper 412 and the second stopper 413. When the first stopper 23 abuts against the first stopper 412, the locking mechanism 10 is in a locked state. When the second stopper 24 abuts against the second stopper 413, the locking mechanism 10 is in a released state.

[0055] See also Figures 8 to 13 , one end of the locking member 11 is telescopically mounted on the second fixed seat 51, and the other end of the locking member 11 protrudes out of the arc groove 411 and is provided with a mounting portion 112 that cooperates with the transmission member 13. Specifically, the mounting portion 112 is a through mounting hole, and the transmission member 13 is inserted into the mounting hole. The mounting portion 112 can also be a clamping portion that is clamped and fixed with the transmission member 13. As long as the locking member 11 and the transmission member 13 can be connected together and the transmission member 13 drives the locking member 11 to move, the present invention does not make specific restrictions on this. On the other hand, a second reset member 15 is provided on the locking member 11 to make the locking member 11 always have a reset tendency. When the driving member 20 rotates and resets, in order to prevent the transmission member 13 from being stuck between the fixed seat 13 and the driving inclined surface 21, a second reset member 15 that drives the locking member 11 to reset is provided on the locking member 11, so that the locking member 11 always has a tendency to lock with the positioning member 12. Specifically, the second restoring member 15 is a spring structure, and the second restoring member 15 may also be other elastic structures that can be compressed and released.

[0056] See also Figures 8 to 14In some optional embodiments, a first reset member 14 is provided on the first fixed seat 41 so that the driving member 20 always has a reset tendency. Specifically, the first reset member 14 is a tension spring. When the driving member 20 rotates along the first fixed seat 41, the tension spring will be deformed by force. When the force acting on the driving member 20 is withdrawn, the tension spring will drive the driving member 20 to reset. In this embodiment, the outer periphery of the driving member 20 is a circular structure so that it can be rotatably matched with the first fixed seat 41. The driving member 20 is connected to the first fixed seat 41 on the backrest portion 40. When the backrest portion 40 is unfolded relative to the seat portion 50, or the backrest portion 40 is folded relative to the seat portion 50, the driving inclined surface 21 on the driving member 20 is at a position away from the transmission member 13. At this time, the operation of the operating member 30 cannot cause the driving inclined surface 21 to act on the transmission member 13. . When the backrest portion 40 is folded relative to the seat portion 50, the driving member 20 rotates with the first fixing seat 41 to a position where the driving inclined surface 21 can drive the transmission member 13. At this time, the operating member 30 is operated to allow the driving member 20 to rotate relative to the first fixing seat 41. The rotation of the driving member 20 causes the driving inclined surface 21 to act on the transmission member 13 to drive the locking member 11 to disengage from the positioning member 12, so that the seat portion 50 with the backrest portion 40 folded can rotate relative to the frame, and the position of the seat portion 50 and the backrest portion 40 relative to the frame can be adjusted, so that the overall volume of the child carrier after folding is smaller, and it is more convenient to carry and store.

[0057] like Figures 1 to 14As shown, the foldable child carrier 100 of the present invention comprises a frame, a seat portion 50 and a backrest portion 40 folded on the seat portion 50. The seat portion 50 is pivotally connected to the frame, and the backrest portion 40 can be folded relative to the seat portion 50. A locking mechanism 10 is also provided between the seat portion 50 and the frame, and the locking mechanism 10 can lock the seat portion 50 to the frame, and when the locking mechanism 10 is released, the seat portion 50 can be rotated relative to the frame. A driving member 20 for driving the locking mechanism 10 is also connected between the backrest portion 40 and the seat portion 50. When the backrest portion 40 is in an unfolded state relative to the seat portion 50, or when the backrest portion 40 is in a rotating and folding process, the driving member 20 cannot release the locking mechanism 10, the locking mechanism 10 is in a locked state, and the seat portion 50 cannot rotate relative to the frame. When the backrest 40 is folded relative to the seat 50, the driving member 20 rotates with the first fixing seat 41 to be close to the transmission member 13. At this time, the activity of the driving member 20 can drive the locking mechanism 10 to release the lock, so that the seat 50 can rotate relative to the frame. In the foldable child carrier 100 of the present invention, the driving member 20 that drives the locking mechanism 10 can only act on the locking mechanism 10 when the backrest 40 is folded, which can effectively prevent the child carrier from being misused during use, and is safer and more reliable. After the backrest 40 of the foldable child carrier 100 of the present invention is folded relative to the seat 50, the activity of the driving member 20 can release the locking mechanism 10, so that the seat 50 and the frame are released, so that the seat 50 can rotate relative to the frame to adjust the relative position between the seat 50 and the frame, so that the overall volume is smaller and more convenient to carry and store. The foldable child carrier 100 of the present invention has a novel structure, is easy to operate, safe and reliable, and is easy to carry and store.

[0058] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope of the present invention.
