DETAILED DESCRIPTION

[0060] like Figure 1 As shown, an embodiment of the present application provides a baby carrier, such as a baby stroller, etc. The baby carrier includes a frame assembly, and the frame assembly includes a seat 10 and a frame 20. The baby carrier, the frame assembly, and the armrest support rod 110 and the seat support rod 130 of the seat 10 can be folded together with the backrest support rod 120. After folding, the overall volume is small, thereby reducing transportation costs and facilitating storage and placement.

[0061] Specifically, Figure 1 , Figure 2 , Figure 7 , Fig.13 and Fig.24As shown, the seat 10 is a seat 10 that can be folded in linkage with an armrest support rod, and includes a seat support assembly 100, an armrest fixing seat 200, a backrest fixing seat 300, a seat fixing seat 400, a connecting fixing seat 500, a first locking mechanism 620, a second locking mechanism 610, a third locking mechanism 640, and a linkage assembly 700. The frame 20 includes a rider 140, a front foot support rod 150, a rear foot support rod 160, a fourth locking mechanism 630, and a frame fixing seat 631.

[0062] Specifically, Figure 1 As shown, the seat support assembly 100 includes an armrest support rod 110, a backrest support rod 120, a seat support rod 130 and an armrest cross bar 170. The armrest cross bar 170 is disposed transversely in front of the seat assembly 100 for the baby to grasp, and both ends of the armrest cross bar 170 are connected to the armrest support rod 110. The backrest support rod 120 and a backrest body (not shown in the drawings) wrapped outside the backrest support rod 120 form a backrest for supporting the baby's back, and the seat support rod 130 and a seat body (not shown in the drawings) wrapped outside the seat support rod 130 form a seat for supporting the baby's buttocks.

[0063] like Figures 11 to 14 As shown, the armrest fixing seat 200, the backrest fixing seat 300, the seat fixing seat 400 and the connection fixing seat 500 are coaxially pivoted.

[0064] The armrest fixing seat 200 includes a first main body portion 210 and a first connecting portion 220 which are connected to each other. The first main body portion 210 is substantially disc-shaped, and the first connecting portion 220 is substantially sleeve-shaped. The first connecting portion 220 can be used to connect and cooperate with the armrest support rod 110.

[0065] The backrest fixing seat 300 includes a second main body portion 310 and a second connecting portion 320 connected to each other. The second main body portion 310 is roughly annular, that is, a circular first through-hole 311 is formed in the middle of the second main body portion 310. The second connecting portion 320 is roughly sleeve-shaped and is used to connect and cooperate with the backrest support member 120.

[0066] The seat fixing seat 400 includes a third main body 410 and a third connecting portion 420 connected to each other. The third main body 410 is generally in the shape of a truncated cone. A locking boss 411 is formed on the side of the third main body 410 facing the backrest fixing seat 300. A second substantially circular through-hole 412 is formed in the middle of the locking boss 411. The second through-hole 412 is arranged opposite to the first through-hole 311. The third connecting portion 420 is generally in the shape of a sleeve and is used to be sleeved and fixed to the seat support rod 130.

[0067] The connecting and fixing seat 500 is used to fix the seat 10 on the frame 20. The connecting and fixing seat 500 includes a fourth main body 510 that is roughly disc-shaped and a mounting shaft 520 fixed to the middle of the fourth main body 510. The seat fixing seat 400, the backrest fixing seat 300 and the armrest fixing seat 200 are sequentially sleeved on the mounting shaft 520 to achieve coaxial pivot connection. The first connecting portion 220, the second connecting portion 320 and the third connecting portion 420 can be sleeved and fixed on the armrest support rod 110, the backrest support rod 120 and the seat support rod 130 respectively, or connected to the armrest support rod 110, the backrest support rod 120 and the seat support rod 130 respectively by other means, such as fixedly connected by pins, or can be integrally formed with the armrest support rod 110, the backrest support rod 120 and the seat support rod 130 respectively.

[0068] like Figures 6 to 11 As shown, when the backrest fixing seat 300 rotates to the first position relative to the armrest fixing seat 200 (as shown in FIG. Figure 6 and Figure 7 As shown in FIG. 1 ), the first locking mechanism 620 locks the armrest fixing seat 200 with the seat fixing seat 400. When the backrest fixing seat 300 rotates to the second position relative to the armrest fixing seat 200 (as shown in FIG. Figure 8 and Fig. 9 As shown), the first locking mechanism 620 releases the lock on the armrest fixing seat 200 and the seat fixing seat 400, and the first position is different from the second position.

[0069] In this embodiment, the second position can be a position where the backrest fixing seat 300 rotates relative to the armrest fixing seat 200 to a position where the backrest support rod 120 and the armrest support rod 110 are substantially parallel or overlapped, such as Figure 8 As shown, the first position is other than the second position, such as Figure 6 In this way, when the seat 10 needs to be folded, the backrest fixing seat 300 can be rotated from the first position to the second position relative to the armrest fixing seat 200, that is, the backrest support rod 120 and the armrest support rod 110 are roughly parallel or overlapped, and the first locking mechanism 620 releases the lock of the armrest fixing seat 200 and the seat fixing seat 400, and further operation can be performed to fold the armrest support rod 110, the backrest support rod 120 and the seat support rod 130 to a state where the three are roughly parallel, so as to save the storage space after the seat 10 is folded.

[0070] Specifically, Figures 6 to 11As shown, the first locking mechanism 620 includes a first locking portion provided on the armrest fixing seat 200 and a second locking portion provided on the seat fixing seat 400. When the backrest fixing seat 300 rotates to the first position relative to the armrest fixing seat 200, the first locking portion and the second locking portion are locked and matched. When the backrest fixing seat 300 rotates to the second position relative to the armrest fixing seat 200, the first locking portion and the second locking portion are released from matching. In this embodiment, the first locking portion is a snap-fit ​​block 621 provided on the armrest fixing seat 200, and the second locking portion is a snap-fit ​​groove 622 provided on the seat fixing seat 400 and capable of matching with the snap-fit ​​block 621. Of course, the positions of the snap-fit ​​block 621 and the snap-fit ​​groove 622 can also be interchanged, or the first locking mechanism 620 can also adopt other forms, such as snap-fit ​​hooks and snap-fit ​​holes that match each other, etc., without limitation.

[0071] Optional, such as Fig.13 , Fig.15 and Fig.23 As shown, the locking groove 622 is provided on the locking boss 411. The locking block 621 is provided on the side of the armrest fixing seat 200 facing the backrest fixing seat 300, and the first main body 210 of the armrest fixing seat 200 is provided with a radially arranged mounting groove 213 (such as Fig.11 and Fig. 22 As shown in FIG. 2 , the engaging block 621 is disposed in the mounting groove 213, and the engaging block 621 extends from the notch of the mounting groove 213 to cooperate with the engaging groove 622. The locking boss 411 passes through the penetration opening 311 so that the engaging block 621 can be locked and matched with the engaging groove 622.

[0072] Furthermore, if Fig. 9 , Fig.13 , Fig.15 and Fig. 20 As shown, the second main body 310 of the backrest fixing seat 300 has a guide groove 312, and the distance between the guide groove 312 and the notch of the engaging groove 622 is different at different positions, that is, the extension path of the guide groove 312 is gradually changed. Fig.18 The engaging block 621 has an engaging portion 621a and a guide post 621b, wherein the engaging portion 621a can be inserted into the engaging groove 622, and the guide post 621b is inserted into the guide rail groove 312 and moves along the guide rail groove 312. When the backrest fixing seat 300 rotates to the second position relative to the armrest fixing seat 200, the guide rail groove 312 is farthest from the center of the second main body 310, that is, the guide rail groove 312 is farthest from the locking boss 411, and the engaging block 621 moves along the guide rail groove 312 until the engaging portion 621a is disengaged from the engaging groove 622. When the backrest fixing seat 300 rotates to the first position relative to the armrest fixing seat 200, the engaging block 621 moves along the guide rail groove 312 until the engaging portion 621a can be inserted into the engaging groove 622.

[0073] In this way, on the one hand, when the backrest fixing seat 300 is rotated to the first position relative to the armrest fixing seat 200, the first locking mechanism 620 locks the armrest fixing seat 200 and the seat fixing seat 400, and when the backrest fixing seat 300 is rotated to the second position relative to the armrest fixing seat 200, the first locking mechanism 620 releases the lock on the armrest fixing seat 200 and the seat fixing seat 400. On the other hand, during the unfolding process of the seat 10, due to the cooperation of the guide column 621b on the locking block 621 and the guide rail groove 312, the armrest fixing seat 200 and the backrest fixing seat 300 are linked when pivoting, so that the armrest support rod 110 will unfold together with the backrest support rod 120 and even the entire frame assembly, and automatically return to the initial position, thereby realizing the automatic return of the armrest support rod 110 during the unfolding process.

[0074] Furthermore, if Figure 7 , Fig. 9 and Fig.11 As shown, the first locking mechanism 620 also includes a first elastic member 623, the two ends of which are respectively against the armrest fixing seat 200 and the engaging block 621, specifically, the two ends of the first elastic member 623 are respectively against the engaging block 621 and the bottom of the installation slot 213, and the first elastic member 623 makes the engaging block 621 always move in the direction of the engaging slot 622. In this way, after completing the state conversion of the seat, such as from the folded state to the unfolded state, the backrest fixing seat 300 rotates to the first position relative to the armrest fixing seat 200, and the engaging block 621 can be automatically engaged in the engaging slot 622 under the action of the first elastic member 623 to achieve the locking of the armrest fixing seat 200 and the seat fixing seat 400, thereby improving the safety performance.

[0075] Specifically, Figure 7 , Fig.18 and Fig.19 As shown, the first elastic member 623 can be installed in a manner that a mounting platform 621c is provided on the engaging block 621, the mounting platform 621c includes an abutting portion 621d and a protruding portion 621e connected to each other, the first elastic member 623 is partially sleeved outside the protruding portion 621e, and one end of the first elastic member 623 away from the bottom of the mounting groove 213 abuts against the abutting portion 621d. Of course, other methods can also be used to install the first elastic member 623. The first elastic member 623 can be a spring, an elastic rubber column, etc., which is not limited to this.

[0076] Furthermore, if Figures 3 to 9As shown, the second locking mechanism 610 can realize the relative locking of the armrest fixing seat 200 and the seat fixing seat 400, and when the backrest fixing seat 300 rotates to the second position relative to the armrest fixing seat 200, the second locking mechanism 610 can be operated to make the armrest fixing seat 200 rotate relative to the seat fixing seat 400. In this way, when the backrest fixing seat 300 rotates to the second position relative to the armrest fixing seat 200, the second locking mechanism 610 can be operated to release the lock between the armrest fixing seat 200 and the seat fixing seat 400, and the armrest fixing seat 200 and the seat fixing seat 400 rotate relative to each other, and finally make the armrest support rod 110, the seat support rod 130 and the backrest support rod 120 in a state close to parallel, and the armrest support rod 110 does not tilt or extend outward, so that the overall volume is small after folding, reducing transportation costs, and facilitating storage and placement. Due to the clever cooperation of the second locking mechanism 610 and the first locking mechanism 620, a double locking safety function is provided for the baby carrier. If the second locking mechanism 610 is operated alone or the armrest fixing seat 200 is rotated to the second position relative to the backrest fixing seat 300 so that the first locking mechanism 620 is in a released state, the linked folding frame cannot be unlocked. Only when the second locking mechanism 610 and the first locking mechanism 620 are released at the same time, the armrest support rod 110, the backrest support rod 120 and the seat support rod 130 of the linked folding frame can be relatively rotated. This can prevent the seat 10 from being accidentally folded when the second locking mechanism 610 is accidentally touched or the backrest support rod 120 is rotated to be roughly parallel to or overlapped with the armrest support rod 110, thereby greatly improving the safety performance of the baby carrier.

[0077] Specifically, Figure 7 and Fig. 9 As shown, the second locking mechanism 610 includes a third locking portion arranged on the armrest fixing seat 200 and a fourth locking portion arranged on the seat fixing seat 400, and the third locking portion can be operated to cooperate with the fourth locking portion to lock or unlock, or the fourth locking portion can be operated to cooperate with the third locking portion to lock or unlock.

[0078] Alternatively, if Figure 7 and Fig. 9As shown, the third locking part is a locking pin 611 movably arranged on the armrest fixing seat 200, and the fourth locking part is a locking groove 612 arranged on the seat fixing seat 400 and capable of cooperating with the locking pin 611. In this way, the armrest fixing seat 200 and the seat fixing seat 400 can be locked by cooperating with the locking pin 611 and the locking groove 612. By operating the locking pin 611 so that the locking pin 611 is disengaged from the locking groove 612, the second locking mechanism 610 can be unlocked, and the armrest fixing seat 200 and the seat fixing seat 400 can rotate relative to each other, that is, the armrest support rod 110 and the seat support rod 130 can rotate relative to each other. Of course, the positions of the locking pin 611 and the locking groove 612 can also be interchanged, or the third locking part and the fourth locking part can be in other forms, such as hooks and holes that can cooperate with each other, etc., and there is no limitation on this.

[0079] Furthermore, if Figure 7 , Fig. 9 and Figures 13 to 15 As shown, the locking groove 612 is provided on the locking boss 411. In this way, the armrest fixing seat 200 and the backrest fixing seat 300 can be conveniently fixed to each other at different relative positions. The locking pin 611 is provided on the side of the armrest fixing seat 200 facing the backrest fixing seat 300. Specifically, a radially penetrating installation channel 211 can be provided on the first main body portion 210 of the armrest fixing seat 200. One end of the locking pin 611 can pass through the installation channel 211 and cooperate with the locking groove 612, and the other end of the locking pin 611 can protrude from the installation channel 211 for easy operation. The locking boss 411 passes through the first penetration opening 311 so that the locking pin 611 can be locked and cooperated with the locking groove 612. Please also refer to Fig.11 and Fig. 22 Optionally, the mounting groove 213 and the mounting channel 211 are arranged along the same radial direction of the armrest fixing seat 200, that is, the snap block 621 and the locking pin 611 are arranged along the same radial direction of the armrest fixing seat 200, so that the snap block 621 and the locking pin 611 can lock the seat fixing seat 400 from two opposite sides of the armrest fixing seat 200.

[0080] Furthermore, if Fig.16 and Fig.17 As shown, the second locking mechanism 610 further includes a second elastic member 613, the two ends of which are respectively against the armrest fixing seat 200 and the locking pin 611, and the second elastic member 613 causes the locking pin 611 to constantly move in the direction of the locking groove 612. In this way, after the state conversion of the seat 10 is completed, for example, after the state conversion from the folded state to the unfolded state, the locking pin 611 can be automatically snapped into the locking groove 612 under the action of the second elastic member 613 to achieve the locking of the armrest fixing seat 200 and the seat fixing seat 400, without further manual operation of the locking pin 611, which saves time and effort and can improve safety performance.

[0081] Alternatively, if Figure 7 , Fig.16 and Fig.17 As shown, the second elastic member 613 can be arranged in such a manner that a limiting column 212 is arranged on the inner wall of the installation channel 211, a limiting hole 611a arranged in a radial direction is arranged on the locking pin 611, the limiting column 212 is inserted into the limiting hole 611a, and the two ends of the second elastic member 613 are respectively against the limiting column 212 and the hole wall of the limiting hole 611a on the side away from the locking boss 411. In this way, the second elastic member 613 can play the function of assisting the locking pin 611 in resetting. Of course, the second elastic member 613 can also be arranged in other ways. The second elastic member 613 is a spring, an elastic rubber column, etc., which is not limited to this.

[0082] Furthermore, if Figures 3 to 5 As shown, the second locking mechanism 610 also includes an operating member 614 connected to the locking pin 611, and the operating member 614 can be operated to drive the locking pin 611 to move. In this way, it is convenient for the user to operate the locking pin 611, and the user experience is improved. Optionally, the operating member 614 is a webbing, and the use of the webbing as the operating member 614 takes up almost no storage space and hardly increases the overall weight of the baby carrier. Of course, the operating member 614 can also be a pull ring, etc., which is not limited to this. A through hole 615 can be provided at one end of the locking pin 611 protruding from the mounting channel 211, and the webbing can pass through the through hole 615 and be wrapped around and fixed on the locking pin 611. Of course, the webbing can also be fixed to the fixing pin in other ways, which is not limited to this.

[0083] Furthermore, if Fig.24 As shown, the fourth locking mechanism 630 is in a locked state, and the rider 140 and the front foot support rod 150 are relatively locked; the fourth locking mechanism 630 is in a released state, and the rider 140 and the front foot support rod 150 rotate relative to each other. In this way, the fourth locking mechanism 630 can be used to control the locking and releasing of the rider 140 and the front foot support rod 150.

[0084] Specifically, Fig.13 , Fig.15 and Fig.24As shown, the fourth locking mechanism 630 includes a frame fixing seat 631 and a frame releasing member 632 disposed on the frame fixing seat 631. The frame fixing seat 631 is fixed to a side of the connecting fixing seat 500 that faces away from the seat fixing seat 400. The rotation of the armrest fixing seat 200 can drive the linkage assembly 700 to act on the frame releasing member 632, so that the fourth locking mechanism 630 is converted from a locked state to a released state. In this way, when the armrest support rod 110 is rotating and folding or rotating and unfolding, the frame releasing member 632 can be driven to release through the linkage assembly 700, thereby releasing the lock between the rider 140 and the front foot support rod 150, and driving the rider 140 and the front foot support rod 150 to rotate and fold or rotate and unfold together.

[0085] Specifically, Fig.13 , Fig.15 and Fig.24 As shown, the linkage assembly 700 includes a pushing member 720 and a driving member 710 which are sleeved on the mounting shaft 520. The rotation of the armrest fixing seat 200 can drive the driving member 710 to move in the axial direction, so that the driving member 710 pushes the pushing member 720, so that the pushing member 720 pushes the frame release member 632, so that the fourth locking mechanism 630 is converted from a locked state to a released state.

[0086] The driving member 710 can be in various forms. For example, the driving member 710 can include a driving body 711 and a third elastic member 712. The driving body 711 is provided with a first push-inclined surface 711a on a side facing the armrest fixing seat 200. The first main body 210 of the armrest fixing seat 200 is provided with a second push-inclined surface 214 that can cooperate with the first push-inclined surface 711a. The two ends of the third elastic member 712 are respectively against a side of the driving body 711 facing away from the armrest fixing seat 200 and the pushing member 720. The pushing member 720 has a pushing protrusion 721 (such as Fig.15 As shown in FIG. 1 , the pushing protrusion 721 can pass through the connecting fixing seat 500 and abut against the frame release member 632. In this way, when the armrest fixing seat 200 is rotated, the second abutting inclined surface 214 will abut against the first abutting inclined surface 711a, so that the driving body 711 axially abuts against the third elastic member 712, causing the third elastic member 712 to also axially abut against the pushing member 720, and the pushing member 720 then acts on the frame release member 632 through the pushing protrusion 721. Through this interlocking interaction, the linkage folding function of the armrest fixing seat 200, the rider 140, and the front foot support rod 150 is achieved.

[0087] Furthermore, if Figure 1 and Figure 2As shown, the third locking mechanism 640 includes a backrest release member 641 located at the top of the backrest support rod 120. By pressing the backrest release member 641, the angle of the backrest support member 120 relative to the armrest support rod 110 can be adjusted. Specifically, the third locking mechanism 640 is in a locked state, so that the backrest fixing seat 300 and the armrest fixing seat 200 are relatively locked; the third locking mechanism 640 is in a released state, so that the backrest fixing seat 300 and the armrest fixing seat 200 are relatively rotated. By pressing the backrest release member 641, the third locking mechanism 640 can be converted from a locked state to a released state.

[0088] The following is a specific process of converting the armrest support rod-linked folding seat 10 from the unfolded state to the folded state:

[0089] First, the backrest release member 641 is pressed to release the third locking mechanism 640, and the backrest fixing seat 300 can rotate to the second position relative to the armrest fixing seat 200, and the backrest support rod 120 and the armrest support rod 110 are overlapped or parallel, and at the same time, the first locking mechanism 620 is released, and the engaging block 621 is disengaged from the engaging groove 622. At this time, the webbing is pulled to make the locking pin 611 disengage from the locking groove 612, and the second locking mechanism 610 is released, so that the armrest fixing seat 200 and the backrest fixing seat 300 can rotate relative to each other, and respectively drive the armrest support rod 110 and the seat support rod 130 to rotate in the direction close to the backrest support rod 120, and finally make the armrest support rod 110, the seat support rod 130 and the backrest support rod 120 in a nearly parallel state, and the armrest support rod 110 does not tilt or extend outward. At the same time, when the armrest fixing seat 200 rotates, it can act on the frame release member 632 of the fourth locking mechanism 630 through the linkage assembly 700, thereby releasing the lock between the rider 140 and the front foot support rod 150, and driving the rider 140 and the front foot support rod 150 to rotate together to fold or unfold. In this way, the entire frame assembly can be folded.

[0090] The seat 10, frame assembly and baby carrier with the armrest support rod linked to the foldable seat have at least the following technical effects:

[0091] The armrest fixing seat 200, the backrest fixing seat 300 and the seat fixing seat 400 are coaxially connected, and the armrest fixing seat 200 and the seat fixing seat 400 are folded in conjunction with the backrest fixing seat 300. In this way, the armrest fixing seat 200 and the seat fixing seat 400 can be rotated to respectively drive the armrest support rod 110 and the seat support rod 130 to rotate in the direction close to the backrest support rod 120, and finally make the armrest support rod 110, the seat support rod 130 and the backrest support rod 120 in a nearly parallel state, and the armrest support rod 110 does not tilt or extend outward. In this way, the volume of the seat 10 after folding can be greatly reduced, which can reduce the transportation cost on the one hand, and also facilitate the user to store and place it on the other hand, save the occupied space, and improve the user's satisfaction.

[0092] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0093] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
