[0063] Refer to Figures 1 - 7 , this application provides a child carrier 1000 having an unfolded state and a folded state. The child carrier 1000 includes two oppositely arranged side frames 100, a seat assembly 200 disposed between the two side frames 100, and a carrying device 3000. The side frame 100 includes a front foot assembly 110, a rear foot assembly 120, and a push handle assembly 130. Two of the three are hinged to each other, and the third is hinged to at least one of the other two. The seat assembly 200 includes a riding portion 210 connected to the front foot assembly 110, and the riding portion 210 is used for carrying the child's buttocks.

[0064] The carrying device 3000 has a receiving space 301 with an open top. The receiving space 301 is used to carry children, pets or items. Correspondingly, the carrying device 3000 is a baby basket, a pet basket, etc. The carrying device 3000 includes a support frame 300 and adapters 400 arranged on both sides of the support frame 300. Among them, the support frame 300 has a length direction X and a width direction Y as shown in the figure. It includes a top frame 310, a bottom frame 320 and foldable side frames 330 arranged between the top frame 310 and the bottom frame 320. The top frame 310 defines an opening at the top of the receiving space 301. The opening is used for children or items to enter and exit the receiving space 301. The structure of the top frame 310 includes, but is not limited to, a closed circular frame. The bottom frame 320 provides bottom support for the receiving space 301 and is arranged opposite to the top frame 310 up and down. Among them, the carrying device 3000 has a storage state in which the top frame 310 and the bottom frame 320 approach each other, and a use state in which they are away from each other.

[0065] The adapters 400 are arranged on both sides of the support frame 300 in the width direction. The specific connection position can be one of the top frame 310, the bottom frame 320 or the side frame 330. When the child carrier 1000 is in the unfolded state, the seating part 210 is supported on the bottom of the bottom frame 320. When the child carrier 1000 is in the folded state; the carrying device 3000 is in the storage state at the same time. The push handle assembly 130 and the front foot assembly 110 rotate and approach the rear foot assembly 120, and drive the carrying device 3000 and the seating part 210 to approach the rear foot assembly 120 respectively. During the folding process, the seating part 210 and the carrying device 3000 move away from each other. During the unfolding process, the seating part 210 and the carrying device 3000 approach each other until the seating part 210 abuts and is supported on the bottom of the bottom frame 320.

[0066] Among them, the seat assembly 200 further includes a backrest 220. The present application provides a structure of one of the backrests 220: The child carrier 1000 includes a flexible cloth cover 230 ( Figure 3 the dotted line in the figure). The flexible cloth cover 230 includes a first part 231 arranged on the seating part 210, and a second part 232 connected to the push handle assembly 130 as the backrest 220. The second part 232 and the push handle assembly 130 are detachably connected. The adapter 400 and the push handle assembly 130 are detachably connected. When installing the carrying device 3000, the second part 232 can be detached. Since the second part 232 is flexible, it does not affect the installation and use of the carrying device 3000. After removing the carrying device 3000, reassemble the second part 232 with the push handle assembly 130, and it can be used for children to sit.

[0067] For the children's vehicle of the present application, the seat assembly is always installed between the two side frames, and the carrying device is detachably connected to the two side frames. After the carrying device is installed, the bottom of the carrying device is supported by the seat assembly, improving the use stability of the carrying device. After the carrying device is removed, it can be used for children to ride, saving the trouble of carrying an extra seat and being more convenient.

[0068] See Figure 8 and Figure 9 In an embodiment, the support frame 300 is rotatably connected to the adapter 400 and is used to adjust the relative position of the carrying device 3000 in the folded state so that the push handle assembly 130 can be closer to the rear foot assembly 120. Among them, the adapter 400 has a first limiting portion 411 and a second limiting portion 412 that act on the support frame 300 to limit the rotation amplitude of the support frame 300. When the children's vehicle 1000 is in the unfolded state, the seating portion 210 is supported on the bottom frame 320, and the first limiting portion 411 acts on the support frame 300 to limit the rotation of the support frame 300. When the children's vehicle 1000 is in the folded state, the rear foot assembly 120 and the second limiting portion 412 act on the support frame 300 to limit the rotation of the support frame 300. Preferably, when the children's vehicle 1000 is in the folded state, the push handle assembly 130 and the rear foot assembly 120 clamp the support frame 300 to keep it fixed. Among them, when the children's vehicle 1000 is in the folded state, the push handle assembly 130 and the rear foot assembly 120 or the front foot assembly 110 are supported on the ground to keep the children's vehicle 1000 standing on the ground for convenient storage.

[0069] In the figure, the adapter 400 is provided with a first rotating seat 413, and the support frame 300 is provided with a second rotating seat 321. The second rotating seat 321 and the first rotating seat 413 are rotationally matched. Among them, the second rotating seat 321 has a limiting block 322 protruding outward along the first rotation axis. The first rotating seat 413 is provided with a group of limiting ribs around the first rotation axis. A group includes two limiting ribs, and the two limiting ribs serve as the first limiting portion 411 and the second limiting portion 412 respectively. When the children's vehicle 1000 is in the unfolded state or the folded state, the limiting block 322 abuts against the first limiting portion 411 or the second limiting portion 412 respectively.

[0070] Refer back to Figures 1 - 7 The side frame 100 includes but is not limited to those shown in the drawings:

[0071] The tops of the front foot assembly 110 and the rear foot assembly 120 are hinged to each other. The push handle assembly 130 includes a handle bar, a side handle bar 133 and a first link 134. The handle bar includes an upper handle bar 131 and a lower handle bar 132 which are hinged to each other. The lower handle bar 132 is hinged to the middle part of the rear foot assembly 120. The top of the side handle bar 133 is hinged to the upper handle bar 131, and the bottom is hinged to the top of the rear foot assembly 120. Among them, the upper handle bar 131, the lower handle bar 132, the rear foot assembly 120 and the side handle bar 133 form a foldable first four-bar linkage mechanism. One end of the first link 134 is hinged to the front foot assembly 110, and the other end is hinged to the bottom of the lower handle bar 132. When folding, the push handle assembly 130 closes to the rear foot assembly 120, and drives the front foot assembly 110 to rotate and close to the rear foot assembly 120 through the first link 134.

[0072] Among them, the adapter 400 is arranged on both sides of the bottom frame 320 and is detachably connected to the side handle bar 133. On the one hand, the adapter 400 is arranged on the bottom frame 320, which can make the adapter 400 as close as possible to the bottom of the side handle bar 133 (i.e., close to the following second rotation axis 101), and the adapter 400 is arranged in the middle or near the middle of the length direction of the bottom frame 320, so that after the loading device 3000 is installed, the center of gravity of the children's carrier 1000 is at least basically not offset in the horizontal direction.

[0073] See Figure 10 , in an embodiment, the children's carrier has a third limiting part 1351 and a fourth limiting part 1131. Among them, at least in the unfolded state of the children's carrier 1000, the third limiting part 1351 and the fourth limiting part 1131 act on the top and bottom of the adapter 400 respectively to limit the sliding of the adapter 400 relative to the push handle assembly 130, and further improve the use stability of the loading device 3000.

[0074] The setting positions and structural forms of the third limiting part 1351 and the fourth limiting part 1131 are not limited. For example, the third limiting part 1351 and the fourth limiting part 1131 can be bumps protruding on the side frame, etc.

[0075] For another example, the children's carrier 1000 includes a transverse member 113 arranged between the two side frames 100. At least in the unfolded state of the children's carrier 1000, both ends of the transverse member 113 act as the fourth limiting part 1131 and abut against the bottom of the adapter 400.

[0076] In one embodiment, the seating portion 210 is a frame structure comprising two bases 211 fixedly connected to corresponding front leg assemblies 110, and a plurality of crossbars 212 connected between the two bases 211. A cross member 113 is a rod that extends through the rear portion of the bases 211 and serves as one of the crossbars 212 to form the seating portion 210. The axis of the cross member 113 is coaxial with the second rotation axis 101. Preferably, during the folding process of the child carrier 1000, the third stopper 1351 and the fourth stopper 1131 act on the top and bottom of the adapter 400, respectively.

[0077] As shown, the front foot assembly 110 includes a front foot bar 111 and a front wheel 112 disposed at its bottom. The rear foot assembly 120 includes a rear foot bar 121 and a rear wheel 122 disposed at its bottom. A cross member 113 is connected between the two front foot bars 111 of the two side frames 100. The front foot assembly 110, the rear foot assembly 120, and the side support bars 133 are coaxially hinged about the second rotation axis 101. The rear foot assembly 120 and the side support bars 133 lie in a plane, with the front foot assembly 110 located inside the rear foot assembly 120 (the inside being the space between the two side frames 100). A guide portion 114 with a circular surface (centered on the second rotation axis 101) is provided at the top of the front foot bar 111. The end of the cross member 113 is inserted into the guide portion 114, and in this case, the cross member 113 is considered part of the front foot assembly. During the folding and unfolding process, the bottom of the adapter 400 always contacts the guide portion 114 , thereby guiding the movement of the carrying device 3000 .

[0078] See again Figures 1 - 8 In one embodiment, a second folding link is provided between the side support rod 133 and the lower handlebar 132. The side support rod 133, the lower handlebar 132, and the second folding link form a second four-bar linkage. The second folding link includes a second link 135 hingedly connected to the side support rod 133 and a third link 136 hingedly connected to the lower handlebar 132. The second link 135 is used to detachably mount an armrest assembly (not shown). Specifically, after the support device 3000 is disassembled and a child is riding, the armrest assembly is installed to improve safety. At this time, when the side frame 100 is folded, the armrest assembly can be driven to move closer to the rear leg assembly 120 along with the second link 135.

[0079] Part of the second connecting rod 135 serves as a third limiting portion 1351 to abut against the top of the adapter 400 .

[0080] See also Figures 11 - 15Regarding the adapter 400, it includes a first arm 410 and a second arm 420. The first arm 410 is connected to the support frame 300, and its bottom abuts against the fourth limit portion 1131. The second arm 420 is hinged to the first arm 410 and has a first state in which it and the first arm 410 enclose and tightly embrace the push handle assembly 130, and a second state in which it separates to release the push handle assembly 130. In the second state, the adapter 400 is allowed to detach from the side frame 100. The adapter 400 also includes an operating member 430 rotatably connected to the second arm 420 and a locking member 440 rotatably connected to the operating member 430. The locking member 440 has the following features:

[0081] Locking state, interacting with the first holding arm 410 to keep the first holding arm 410 and the second holding arm 420 in the first state;

[0082] In the unlocked state, the operating member 430 releases the interaction with the first arm 410, placing the first arm 410 and the second arm 420 in the second state. Compared to the prior art, the adapter 400 of the carrier 3000 is directly mounted on the handle assembly 130 to achieve connection, simplifying the structure of the side frame 100.

[0083] See again Figures 5 - 7 In one embodiment, when the child carrier 1000 is unfolded, the side rails 133 and the rear leg bars 121 are approximately 90 degrees apart, and the bottom frame 320 extends along a horizontal plane and is approximately 40 degrees relative to the side rails 133. When folded, the side rails 133 and the rear leg bars 121 are approximately 10 degrees apart, and the bottom frame 320 is approximately parallel to the rear leg bars 121. This angle minimizes the aforementioned rotation range.

[0084] See also Figure 5 and Figures 16 - 18 Regarding the carrying device 3000 , in one embodiment, the side frames 330 drive the top frame 310 and the bottom frame 320 to align and move closer together when folded, and drive the top frame 310 and the bottom frame 320 to align and move apart when unfolded.

[0085] The carrying device 3000 also includes a connecting base 340 and a driving member. The connecting base 340 is used to connect the two side frames 330 and is slidably mounted on the bottom frame 320. The connecting base 340 has a first position and a second position along the sliding path. When the connecting base 340 slides between the two positions, the corresponding side frames 330 switch between a folded state and an unfolded state. The driving member is used to drive the connecting base 340 to slide from the first position to the second position to unfold the side frames 330. The side frames 330 shown in the figure are:

[0086] The side frame 330 includes a plurality of first side blocking rods 331. Each first side blocking rod 331 is inclined in the same direction. For example, there is a certain angle between the top frame 310 and the bottom frame 320. Another example is that in the illustrated figure, the top frame 310 and the bottom frame 320 are parallel to each other, then the first side blocking rods 331 are also parallel to each other. The connecting seat 340 is connected to all the first side blocking rods 331 to realize the synchronous movement of the first side blocking rods 331, ensuring that the side frames 330 on both sides can be folded or unfolded synchronously. Further, the side frame 330 further includes a second side blocking rod 332. One end of the second side blocking rod 332 is hinged to the first side blocking rod 331, and the other end is hinged to the bottom frame 320. The inclination direction of the second side blocking rod 332 is opposite to that of the first side blocking rod 331, improving the structural stability of the support skeleton 300 in the unfolded state.

[0087] During actual operation, when the support skeleton 300 is in the folded state, the operating drive member drives the connecting seat 340 to move in the first direction. The upper part of the first side blocking rod 331 moves upward to drive the top frame 310 away from the bottom frame 320 until the support skeleton 300 is in the unfolded state; when folding, press down the top frame 310 so that the connecting seat 340 slides in the second direction until the support skeleton 300 is in the folded state. Compared with the prior art, the unfolding operation is more convenient.

[0088] The carrying device 3000 further includes a cloth pocket 370 connected between the top frame 310 and the bottom frame 320 and wrapping the side frame 330. In the unfolded state, the cloth pocket 370 pulls the top frame 310 and the bottom frame 320 to make the support skeleton 300 unfold to the maximum height, indirectly restricting the connecting seat 340 from continuing to move in the pulling direction.

[0089] Among them, the connecting seat 340 can be a cross bar, or a frame composed of multiple rods, or a component slidably sleeved on the bottom frame, etc. For example Figure 16 As shown, in an embodiment, the connecting seat 340 is a frame structure, including two cross bars 341 respectively corresponding to two pairs of first side blocking rods 331, and at least one longitudinal rod 342 connected between the two cross bars 341. The two ends of the cross bar 341 are slidably matched with the bottom frame 320, and the side frames 330 on both sides are hinged to the connecting seat 340. For example, a pair of first side blocking rods 331 symmetrically arranged in the two side frames 330 are hinged to one of the cross bars 341, and the other pair of first side blocking rods 331 are hinged to the other cross bar 341. Another example is that the connecting seat 340 includes a sliding member slidably matched with the bottom frame 320 and a transverse member connecting the two sliding members, and the first side blocking rods 331 on the same side are hinged to the sliding member.

[0090] Further, the carrying device 3000 further includes a locking device 360 for locking the support frame 300 to keep it in the unfolded state. The locking can be provided between the connecting seat 340 and the bottom frame 320, that is, the connecting seat 340 is locked.

[0091] In some embodiments, the locking device 360 locks by restricting the movement of the driving member. It should be emphasized that the object of action of the locking device 360 is the driving member. Specifically, the driving member is a flexible member 350. The flexible member 350 unfolds the support frame 300 by pulling the connecting seat 340. The flexible member 350 is in the shape of a strip or a line or a combination of the two shapes, such as a nylon webbing or a steel wire, or a combination of the two. When the carrying device of the present application is unfolded, the locking device 360 acts on the corresponding position of the flexible member 350 to keep the support frame 300 always in the unfolded state, avoiding folding due to improper locking and causing safety accidents.

[0092] Among them, the flexible member 350 has a fixed end 351 and an operating end 352. The operating end 352 is exposed outside the support frame 300, and when pulling and unfolding, the length of the operating end 352 exposed outside the support frame 300 increases. The connection relationship between the flexible member 350 and the connecting seat 340 adopts at least one of the following:

[0093] a) The fixed end 351 is fixedly connected to the bottom frame 320, and the operating end 352 bypasses the connecting seat 340 and is on the same side of the connecting seat 340 as the fixed end 351 (for example Figure 17 ), preferably, the operating end 352 bypasses one of the cross bars 341, and the outer contour of the contact part between the cross bar 341 and the flexible member 350 is circular, such as a round bar, which is convenient for the movement of the flexible member 350;

[0094] b) The fixed end 351 is fixedly connected to the connecting seat 340 (for example Figure 18 ).

[0095] Among them, the locking device 360 allows the flexible member 350 to move in the pulling direction (corresponding to the connecting seat moving in the first direction), and prevents the flexible member 350 from moving in the opposite direction (i.e., the following retracting direction) (corresponding to the connecting seat moving in the second direction). The locking device 360 has:

[0096] A locking state, allowing the flexible member 350 to move unidirectionally in the pulling direction, that is, restricting the flexible member 350 from moving in the retracting direction;

[0097] An unlocking state, allowing the flexible member 350 to move bidirectionally.

[0098] Such as Figures 19 - 22As shown, the locking device 360 includes a locking base 361, a locking member 362, and an elastic member acting on the locking member 362. A channel 363 for the flexible member 350 to pass through is formed between the locking member 362 and the locking base 361. In the locked state, the locking member 362 and the locking base 361 clamp the flexible member 350, and in this state, the locking member 362 can only rotate in one direction. Specifically, the locking member 362 is rotatably mounted on the locking base 361, and an elastic member (such as a torsion spring) is provided between the two. The locking member 362 is provided with locking teeth 364, and the locking teeth 364 and the locking base 361 provide a clamping force.

[0099] The locking member 362 rotates relative to the locking base 361 and has an unlocking direction ( Figure 22 as indicated by the arrow in Figure 22 ), and a locking direction. As Figure 21 shown, when the operating end 352 of the flexible member 350 moves along the pulling direction, a force is applied to rotate the locking member 362 in the unlocking direction, thereby reducing or even eliminating the clamping force of the locking member 362 and the locking base 361 on the flexible member 350; as Figure 21 shown, when the operating end 352 of the flexible member 350 moves along the retracting direction, a force is applied to rotate the locking member in the locking direction, gradually increasing the clamping force of the locking member 362 and the locking base 361 on the flexible member 350, similar to self-locking. This structure realizes the aforementioned operation that the flexible member 350 can move in one direction, enables the locking device 360 to act on any position of the flexible member 350, ensures that the support frame is in the unfolded state, and thus ignores the error effects caused by processing and assembly. Before folding the carrying device, manually press the locking member 362 to unlock it, and then apply pressure to the top frame 310 to perform the folding operation.

[0100] Among them, the locking device 360 is arranged on the edge of the bottom frame 320, for example, on one side in the X direction in the figure. In one embodiment, the locking member 362 is restricted from further rotating in the locking direction in the locked state. The restricting method can be that a limiting portion that abuts against the locking member 362 is provided on the locking base 361. The limiting portion is, for example, a boss on the locking base 361. In one embodiment, a connecting structure for fixing the flexible member 350 is provided between the flexible member 350 and the cloth pocket 370. The connecting mechanism is, for example, a magic fastener provided between the flexible member 350 and the cloth pocket 370, to prevent the part of the flexible member 350 exposed outside the cloth pocket 370 from swaying randomly.

[0101] Combined with the aforementioned adapter 400 arranged on the bottom frame 320, the unfolding process includes: after the side frame 100 is unfolded, the carrying device 3000 is still in the stored state. Subsequently, hold the side frame 100 or the bottom frame 320 with one hand, and / or press the rear foot assembly 120 with the foot, and then pull the flexible member 350 to unfold the carrying device 3000 to switch to the use state.

[0102] For the children's vehicle of the present application, the seat assembly is always installed between the two side frames, and the carrying device is detachably connected to the two side frames. After the carrying device is installed, the bottom of the carrying device is supported by the seat assembly, improving the use stability of the carrying device. After the carrying device is removed, it can be used for children to ride, saving the trouble of carrying an extra seat and being more convenient.

[0103] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification. When the technical features in different embodiments are embodied in the same drawing, it can be regarded that the drawing also discloses the combined examples of the various embodiments involved at the same time.

[0104] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
