[0053] Referring to Figures 1-4 The present application provides a child-carrying device, which includes a support frame 100 and one or more carriers installed on the support frame 100, and the child-carrying device can be a child stroller, a child dining chair, a camping vehicle, etc. Figures 1-4 The displayed child-carrying device is a child stroller, and the support frame 100 thereof includes a front leg assembly 110, a rear leg assembly 120, and a push handle assembly 130. 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 4The push handle assembly 130 includes two opposing push handle rods 131, the front foot assembly 110 includes two opposing front foot rods 111, and the rear foot assembly 120 includes two opposing rear foot rods 121. Further, the push handle assembly 130 also includes a lateral grip rod 132 connected between the two push handle rods 131. In one embodiment, the push handle rods 131 include a lower push handle rod and an upper push handle rod that are slidably engaged, and the grip rod 132 connects to the tops of the two upper push handle rods. In one embodiment, the push handle rods 131, the front foot rods 111, and the rear foot rods 121 converge at a joint 190, the joint 190 having joint elements respectively connected to the push handle rods 131, the front foot rods 111, and the rear foot rods 121.

[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 an embodiment, the first adapter 171 and the first adapter seat 140 are combined, and when the first carrier 170 is installed on the support frame, the first carrier 170 shields the unlocking member 160, avoiding the unlocking member 160 from being touched by children and others, especially when the children are riding, thereby improving the safety of use. 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, and then the first adapter seat 140 is adjusted to the first position or the second position.

[0059] As shown in Figures 6-8 In an embodiment, the unlocking member 160 is movably arranged on the first adapter seat 140, and when the first adapter 171 and the first adapter seat 140 are separated, the unlocking member 160 is exposed to the first adapter seat 140, and when the first adapter 171 and the first adapter seat 140 are combined, the first adapter 171 shields 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 is rotated to approach 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 also has a folded state and an unfolded state, and in the folded state, the backrest part is approached to the seat cushion part, and then the whole is rotated to approach 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, is slidably or rotatably arranged 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 is 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 pushes the locking part to exit the locking groove 141, thereby releasing the lock, and when the acting force is removed from the operating part 160, the locking member 150 is reset under the action of the elastic member 151.

[0062] As shown in Figure 6 and Figure 8As shown, in one embodiment, the first adapter 140 includes a disc-shaped engaging member 142 and a sliding member 143 that slidably engages with the support frame 100. The support frame 100 is provided with a slide rail 133 that engages with the sliding member 143. The slide rail 133 is disposed inside the push handle 131 and extends along the length of the push handle 131. The sliding member 143 has a groove along the push handle 131, increasing the engagement area with the slide rail 133 and improving sliding stability.

[0063] The rear side of the engaging component 142 has an annular groove 1421 extending circumferentially, used to restrict the axial movement of the first carrier 170 and its disengagement from the first adapter 140, while allowing the first carrier 170 to rotate for folding. In one embodiment, a positioning member is movably disposed on the first adapter 171 to restrict the rotation of the first carrier 170, and a positioning groove 144 is provided on the engaging component 142 to cooperate with the positioning member. In one embodiment, the first carrier 170 has two mounting postures, one facing forward and the other facing backward.

[0064] like Figure 8 As shown, in one embodiment, the central region of the engaging member 142 is provided with a recess 145 for concealing the unlocking member 160. When the first adapter 171 and the first fitting seat 140 are engaged, the opening of the recess 145 is closed. The operating part 161 of the unlocking member 160 protrudes from the bottom wall of the recess 145 for easy pressing and unlocking.

[0065] In one embodiment, the child support device is a stroller, with a first adapter seat 140 slidably mounted on the push handle 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 one embodiment, the first adapter seat 140 is located inside the joint 190 in the first position.

[0066] When the first adapter seat 140 switches from the first position to the second position, a certain space is cleared below, which can be used to install other accessories or carriers. In one embodiment, the stroller includes a second carrier 180 for carrying a child, which can be used for the child to lie down or sit, such as a seat, sleeping box, car seat, infant carrier, etc. The first carrier 170 and the second carrier 180 may be the same or different. In one embodiment, a second adapter seat 200 is provided on the front leg assembly 110. In the figure, there are two second adapter seats 200, which are respectively provided on the two front leg posts 111. The second carrier 180 has a second adapter 181 that can be releasably coupled to the second adapter seat 200.

[0067] The stroller has two usage modes, such as Figure 1 In the first usage 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. At this time, the stroller can be referred to as a single-person riding 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, at which time the stroller can be referred to as a double-riding mode.

[0068] Referring back to Figure 1 and Figure 2 In an embodiment, the second adapter seat 200 is movably connected with the front leg assembly 110 and has a use position and a folding position. In the first use mode, the second adapter seat 200 is in the folding position, and in the second use mode, the second adapter seat 200 is in the use position. The use position and the folding position are different at least in the height direction, for example, the use position is higher than the folding position, and the use position is relatively forward to the folding position, so as to avoid interference between the second carrier 180 and the first carrier 170. In the illustrated embodiment, the front leg assembly 110 further includes a crossbar 113 connected to the bottom of the two front leg rods. The crossbar 113 is a step plate, and the first carrier 170 is installed above the step plate. When viewed in the width direction, the second adapter seat 200 extends out of the upper surface of the front leg assembly 110 in the use position, and in the folding position, the second adapter seat 200 slides downward and does not protrude out of the upper surface of the front leg assembly 110, so as to make the appearance more simple and avoid unnecessary collisions between the user and the second adapter seat 200.

[0069] As Figure 9 The present application provides an adapter installation 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 folding 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 installation structure further includes a foolproof member 220. When the second adapter seat 200 is in the use position, the foolproof member 220 allows the second adapter seat 200 to be combined with the second adapter 181 in the use position. When the second adapter seat 200 is in the folding position, the foolproof member 220 prevents the second adapter seat 200 from being combined with the second adapter 181 in the folding position, so as to avoid 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 member 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. Further, the foolproof member 220 is connected with the second adapter seat 200. The foolproof member 220 is movably arranged on the mounting seat 210. When the second adapter seat 200 is switched between the use position and the folding position, the foolproof member 220 is simultaneously switched between the avoiding position and the blocking position.

[0072] In one embodiment, the foolproof part 220 is rotatably or slidably mounted on the mounting base 210. The adaptive mounting structure further comprises an elastic member 230 for driving the foolproof part 220 to return to the blocking position. Figure 16 In one embodiment, the foolproof part 220 is rotatably mounted on the mounting base 210, and the elastic member 230 is a spring and acts between the foolproof part 220 and the mounting base 210.

[0073] For the convenience of operation, the foolproof part 220 has a driving slope 221, and when the second adapter 200 is moved from the folded position to the use position, the second adapter 200 acts on the driving slope 221 to drive the foolproof part 220 to switch from the blocking position to the avoiding position. In one embodiment, the second adapter 200 has an avoiding opening 204, and in the use position, the foolproof part 220 is aligned with the avoiding opening 204 and is switched to the blocking position by protruding out of the avoiding opening 204 under the action of the elastic member 230; in the folded position, the foolproof part 220 is misaligned with the avoiding opening 204 and is switched to the avoiding position by rotating under the action of the second adapter 200, while the elastic member 230 is compressed.

[0074] Referring to Figures 13-15 In one embodiment, the second adapter 200 and the mounting base 210 are slidably fitted, specifically, the second adapter 200 comprises an axial base 201 and a clamping portion 202, the base 201 and the mounting base 210 are slidably fitted, and a clamping groove 203 is formed between the base 201 and the clamping portion 202, and after the second adapter 181 is combined with the second adapter 200, at least part of the second adapter 181 is placed in the clamping groove 203 to limit the axial movement of the second carrier 180. Wherein, the avoiding opening 204 is arranged on the base 201, and the foolproof part 220 protrudes out of the avoiding opening 204 and extends into the clamping groove 203 when in the blocking position.

[0075] In one embodiment, the base 201 of the second adapter 200 is a disc-shaped structure and has an axis, and the clamping groove 203 is an annular clamping groove, and when the second adapter 181 and the second adapter 200 are combined, the two can rotate around the axis. The mounting base 210 is a waist-shaped structure, the base 201 is a waist-shaped structure and is adapted to the shape of the mounting base 210, and in the folded position, the outer periphery of the mounting base 210 and the base 201 is flush.

[0076] Continuing to refer to Figures 13-15In an embodiment, the adapter mounting structure further comprises a second locking member (hereinafter referred to as second locking member 250) for locking the second adapter seat 200 in the use position or the collapsed position. The second locking member 250 is movably arranged on the second adapter seat 200, for example, rotatably or slidably. In the illustrated embodiment, the second locking member 250 is rotatably arranged on the base 201 of the second adapter seat 200 and has a second locking portion 2501 on both sides of the rotation axis and a second operating portion 2502. The mounting seat 210 is provided with a second locking groove 2101 that cooperates with the second locking portion 2501. The second locking member 250 is provided with a torsion spring at the position of the rotation axis of the second locking member 250, which keeps the second locking portion 2501 extended into the second locking groove 2101. When unlocking, the second operating portion 2502 is pressed, and the second locking portion 2501 is lifted out of the second locking groove 2101. In an embodiment, the second locking groove 2101 is two, corresponding to the use position and the collapsed position respectively.

[0077] As Figures 13-15 In another embodiment, the second locking groove 2101 is one and corresponds to the use position, and the adapter mounting structure further comprises a third locking member 260 for locking the second adapter seat 200 in the collapsed position. The third locking member 260 is rotatably or slidably arranged on the mounting seat 210, and the base 201 is provided with a third locking groove 2011 that cooperates with the third locking member 260. The mounting seat 210 is provided with an elastic member that acts on the third locking member 260 to extend into the third locking groove 2011. For example, the third locking member 260 is rotatably arranged in the mounting seat 210, and the elastic member is a torsion spring. The second locking member 250 further has a second transmission portion 2503 that drives the third locking member 260 to exit the third locking groove 2011. In the collapsed position, the second transmission portion 2503 is aligned with the third locking groove 2011.

[0078] Referring to Figure 17 and Figure 18 A stroller is provided, comprising a support frame 100 and a carrier 300 for a child to stand on. The support frame 100 is as described in the foregoing embodiments and will not be repeated here. The carrier 300 is movably connected with the rear leg assembly 120 and has a first use position relatively closer to the front and a second position relatively further to the front. In actual use, the carrier 300 can be adjusted to an optimal position according to the height and body shape of the child, or according to different use scenarios of the stroller. For example, the carrier 300 is adjusted to the first use position in a first use mode, and the carrier 300 is adjusted to the second use position when the stroller is in a second use mode and the first carrier 170 is positioned relatively further to the front.

[0079] To improve the load-bearing capacity of the load-bearing member 300, the rear foot assembly 120 includes two oppositely arranged rear foot rods 121 and a transverse connector 123 connecting the two rear foot rods.

The transverse connector 123 and the transverse support member 125 are arranged front and rear, with two sliding seats 310 installed on them at intervals along the width direction. In the first use position, the center of gravity of the bearing member 300 is located in front of the transverse connector 123. In the second use position, the center of gravity of the bearing member 300 is located behind the transverse connector 123. The bearing member 300 includes an upper part 320 and a lower part 330. The upper part 320 and the lower part 330 are engaged and / or threaded. The lower part 330 slides with the sliding seat 310. The upper surface of the upper part 320 is provided with anti-slip texture. 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.
