The front leg assembly 110 is arranged upwardly inclined from front to back, the rear leg assembly 120 is arranged downwardly inclined from front to back, and the push handle assembly 130 is arranged upwardly inclined from front to back. The bottom of the front leg assembly 110 is provided with a front wheel 112, and the bottom of the rear leg assembly 120 is provided with a rear wheel 122.

[0054] As Figure 3 And Figure 4 The push handle assembly 130 includes two oppositely arranged push handle rods 131, the front leg assembly 110 includes two oppositely arranged front leg rods 111, and the rear leg assembly 120 includes two oppositely arranged rear leg rods 121. Further, the push handle assembly 130 also includes a transverse grip rod 132 connected between the two push handle rods 131. In an embodiment, the push handle rod 131 includes a lower push handle rod and an upper push handle rod in sliding fit, and the grip rod 132 is connected to the top of the two upper push handle rods. In an embodiment, the push handle rod 131, the front leg rod 111, and the rear leg rod 121 are connected at a joint 190, and the joint 190 has joint elements connected with the push handle rod 131, the front leg rod 111, and the rear leg rod 121, respectively.

[0055] like Figure 3 As shown, in one embodiment, joint 190 includes a front leg joint, a rear leg joint, and a push handle joint that are hinged to each other. The front leg joint is connected to the front leg assembly 110, the rear leg joint is connected to the rear leg assembly 120, and the push handle joint is connected to the push handle assembly 130, so that the support frame 100 has a folded state and a stowed state. A linkage is provided between the front leg joint and the push handle joint, which drives the front leg assembly 110 to rotate and move toward the rear leg assembly 120 when the push handle assembly 130 rotates toward the rear leg assembly 120.

[0056] like Figures 5-8 The child carrier includes a first adapter 140, a locking element 150, an unlocking element 160, and a first carrier 170. The first adapter 140 is movably mounted on a support frame 100 and has a first position and a second position relative to the support frame 100. In one embodiment, the first adapter 140 is slidably mounted on the support frame 100; for example, the first adapter 140 is slidably mounted on a push handle assembly 130. Figure 2 There are two first adapter seats 140, which are slidably mounted on the two push handles 131 respectively.

[0057] A first carrier 170 is used to carry a child and can accommodate a child lying down or sitting, such as a seat, sleeping box, car seat, infant carrier, etc. The first carrier 170 has a first adapter 171 that is releasably coupled to a first adapter 140 and can be mounted on or removed from a support frame 100. A locking member 150 locks the first adapter 140 in a first or second position, and an unlocking member 160 actuates the locking member 150 to unlock, allowing the first adapter 140 to switch between the first and second positions.

[0058] In one embodiment, the first adapter 171 and the first adapter seat 140 are combined. When the first carrier 170 is mounted on the support frame, the first carrier 170 shields the unlocking member 160, preventing children and others from accidentally touching the unlocking member 160, which improves safety, especially when children are riding in it. When it is necessary to adjust the position of the first carrier 170, the first adapter 171 and the first adapter seat 140 are separated, the first carrier 170 is removed to expose the unlocking member 160, and then the unlocking operation is performed. Subsequently, the first adapter seat 140 is adjusted to a first position or a second position.

[0059] like Figures 6-8 As shown, in one embodiment, the unlocking member 160 is movably disposed on the first adapter 140. When the first adapter 171 and the first adapter 140 are separated, the unlocking member 160 is exposed to the first adapter 140. When the first adapter 171 and the first adapter 140 are combined, the first adapter 171 covers the unlocking member 160.

[0060] In an embodiment, when the first adapter 171 and the first adapter seat 140 are combined, the two can rotate around an axis, and when folded, the first carrier 170 rotates to close to the front leg assembly 110 or the rear leg assembly 120. The first carrier 170 is a seat, including a seat cushion part and a backrest part, and itself also has a folded state and an unfolded state, in the folded state, the backrest part is close to the seat cushion part, and then the whole rotates to close to the support frame 100.

[0061] Referring to Figures 6-8 In an embodiment, the unlocking member 160 is movably arranged on the first adapter seat 140 along an axis. The locking member 150 is movably arranged on the support frame 100, for example, sliding or rotating along an axis on the support frame 100. The locking member 150 has a locking part extending out of the support frame 100, and the first adapter seat 140 is provided with a locking groove 141 matched with the locking part. The locking member 150 is two and arranged corresponding to the first position and the second position respectively, and the support frame 100 is correspondingly provided with an elastic member 151 (for example, a spring) to drive the locking member 150 to reset. The unlocking member 160 has an operating part 161 and a transmission part 162 acting on the locking member 150. When an acting force is applied to the operating part 160, the transmission part 162 will push the locking part out of the locking groove 141, thereby releasing the lock. When the acting force on the operating part 160 is removed, the locking member 150 resets under the action of the elastic member 151.

[0062] As shown in Figure 6 and Figure 8 In an embodiment, the first adapter seat 140 includes a disc-shaped clamping member 142 and a sliding member 143 slidingly matched with the support frame 100. The support frame 100 is provided with a sliding rail 133 matched with the sliding member 143, and the sliding rail 133 is arranged on the inner side of the push handle rod 131 and extends along the length direction of the push handle rod 131. The sliding member 143 has a sliding groove along the push handle rod 131, which increases the matching area with the sliding rail 133 and improves the sliding stability.

[0063] The rear side of the clamping member 142 is provided with an annular clamping groove 1421 extending in the circumferential direction, which is used to limit the axial movement and disengagement of the first carrier 170 from the first adapter seat 140, and at the same time provides the first carrier 170 with a rotating function for folding. In an embodiment, the first adapter 171 is movably provided with a positioning member limiting the rotation of the first carrier 170, and the clamping member 142 is correspondingly provided with a positioning groove matched with the positioning member. In an embodiment, the first carrier 170 has two installation attitudes, one towards the front side and the other towards the rear side.

[0064] As shown in Figure 8As shown, in an embodiment, the central region of the engaging member 142 is provided with a recessed groove 145 that conceals the unlocking member 160, and the first adapter 171 closes the opening of the recessed groove 145 when the first adapter 171 is combined with the first adapter seat 140. In this embodiment, the operating portion 161 of the unlocking member 160 protrudes from the bottom wall of the recessed groove 145, which facilitates the pressing operation of the unlocking member 160.

[0065] In an embodiment, the child-carrying device is a stroller, and the first adapter seat 140 is slidingly installed on the handlebar assembly 130. The second position is higher than the first position, and the second position is relatively rearward, while the first position is relatively forward. In an embodiment, the first adapter seat 140 is located on the inner side of the joint 190 when the first adapter seat 140 is in the first position.

[0066] When the first adapter seat 140 is switched from the first position to the second position, a space is left below, which can be used to install other accessories or carriers. In an embodiment, the stroller includes a second carrier 180, which is used to carry a child and can be used for the child to lie down or sit, such as a seat, a sleeping box, a car safety seat, a child basket, etc. The first carrier 170 and the second carrier 180 can be the same or different. In an embodiment, the front leg assembly 110 is provided with a second adapter seat 200. In the illustrated embodiment, the second adapter seat 200 is two and is provided on the two front leg rods 111, respectively. The second carrier 180 is provided with a second adapter 181 that can be releasably combined with the second adapter seat 200.

[0067] The stroller has two use modes, as Figure 1 In the first use mode, the first adapter seat 140 is positioned in the first position, and the second carrier 180 is removed from the front leg assembly 110, and the stroller can be referred to as a single-occupant mode. Figure 2 In the second use mode, the first adapter seat 140 is positioned in the second position, and the second carrier 180 is installed on the front leg assembly 110, and the stroller can be referred to as a double-occupant mode.

[0068] Referring back to Figure 1 and Figure 2In an embodiment, the second adapter 200 is movably connected with the front leg assembly 110, and has a use position and a collapsed position, the stroller is in the first use mode when the second adapter 200 is in the collapsed position, and the stroller is in the second use mode when the second adapter 200 is in the use position, the use position and the collapsed position are different at least in the height direction, for example, the use position is higher than the collapsed position, and the use position is forward relative to the collapsed position, so as to avoid the interference between the second carrier 180 and the first carrier 170. In the illustration, the front leg assembly 110 further includes a crossbar 113 connected at the bottom of the two front leg rods, the crossbar 113 is a step, the first carrier 170 is installed above the step, and when the second adapter 200 is in the use position, it protrudes from the upper surface of the front leg assembly 110, and when the second adapter 200 is in the collapsed position, it slides downward and does not protrude from the upper surface of the front leg assembly 110, so as to make the appearance more simple and avoid unnecessary collision between the user and the second adapter 200.

[0069] As Figure 9 The application provides an adapter mounting structure, which includes a mounting seat 210, an adapter seat movably arranged on the mounting seat 210, and an adapter releasably combined with the adapter seat, the adapter seat has opposite use and collapsed positions. The adapter seat can refer to the second adapter seat 200 of the above-mentioned embodiments, and the adapter can refer to the second adapter 181 of the above-mentioned embodiments.

[0070] As Figures 9-16 In an embodiment, the adapter mounting structure further includes a foolproof part 220, the second adapter seat 200 is allowed to be combined with the second adapter 181 when the second adapter seat 200 is in the use position, and the foolproof part 220 prevents the second adapter seat 200 from being combined with the second adapter 181 when the second adapter seat 200 is in the collapsed position, so as to avoid the interference between the first carrier 170 and the second carrier 180 caused by incorrect installation and damage to the components.

[0071] In an embodiment, the foolproof part 220 is movably arranged and has a blocking position for preventing the second adapter seat 200 from being combined with the second adapter 181 and a avoiding position for allowing the second adapter seat 200 to be combined with the second adapter 181. Furthermore, the foolproof part 220 is connected with the second adapter seat 200, the foolproof part 220 is movably arranged on the mounting seat 210, and the second adapter seat 200 is switched between the use position and the collapsed position, and simultaneously, the foolproof part 220 is switched between the avoiding position and the blocking position.

When the support member 300 moves between the first and second use positions, it covers the sliding seat 310, making the appearance more aesthetically pleasing and preventing children from stepping into the air due to the height difference between the support member 300 and the sliding seat 310.

[0082] The lower part 330 includes three parts: the middle part 331 located between the two sliding seats 310, and the side part 332 located outside the two sliding seats 310.

[0083] like Figures 21-23 In one embodiment, the stroller includes a locking member (hereinafter referred to as the fourth locking member 340) that holds the locking support 300 in a first use position and a second use position. The fourth locking member 340 is slidably mounted on the lower part 330 along the extension direction of the transverse connector 123. There are two fourth locking members 340 and they are arranged between two sliding seats 310. In the first use position, the ends of the fourth locking members 340 abut against the ends of the sliding seats 310, and the upper part 320 abuts against the other end of the sliding seats 310. In the second use position, the fourth locking members 340 extend into the fourth locking groove 311 on the sliding seat 310.

[0084] The second unlocking member 350 is arranged on the lower part 330 in sliding mode, is located between the two fourth locking members 340 and is matched with the two inclined surfaces, and the sliding direction of the second unlocking member 350 is perpendicular to the horizontal connecting member 123. The second unlocking member 350 has a driving part which protrudes from the bottom of the lower part 330.

[0085] In an embodiment, a spring is arranged between the two fourth locking members 340 to drive the two fourth locking members 340 to reset, and a spring is arranged in the lower part 330 to drive the second unlocking member 350 to reset. When unlocking, the driving part is operated to drive the second unlocking member 350 to slide and compress the spring 351, to drive the two fourth locking members 340 to slide and compress the spring 341 through the inclined surfaces, and to release the action on the sliding seat 310, so that the position of the bearing member 300 can be adjusted. After the bearing member 300 is adjusted to the desired position, the operation force on the driving part is released, the second unlocking member 350 is reset under the action of the spring 351, and the two fourth locking members 340 are reset under the drive of the spring 341 and extend into the fourth locking groove 311 or are located at the end of the fourth locking member 340 to lock the bearing member 300.
