[0056] In this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0057] See Figures 1-4 This application provides a child carrier, including a support frame 100 and one or more vehicles mounted on the support frame 100. The child carrier can be a stroller, a high chair, a campervan, etc. (Attached) Figure 1-4The displayed child support device is a stroller, whose support frame 100 includes a front leg assembly 110, a rear leg assembly 120, and a push handle assembly 130. The front leg assembly 110 is arranged at an upward angle from front to back, the rear leg assembly 120 is arranged at a downward angle from front to back, and the push handle assembly 130 is arranged at an upward angle from front to back. The bottom of the front leg assembly 110 has a front wheel 112, and the bottom of the rear leg assembly 120 has a rear wheel 122.

[0058] like Figure 3 and Figure 4 The 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] In one embodiment, when the first adapter 171 and the first fitting seat 140 are combined, they can rotate about an axis. When folded, the first carrier 170 rotates and approaches the front leg assembly 110 or the rear leg assembly 120. The first carrier 170 is a seat, including a seat cushion and a backrest, and it also has a folded state and an unfolded state. In the folded state, the backrest approaches the seat cushion, and then the whole unit rotates and approaches the support frame 100.

[0065] See Figures 6-8As shown, in one embodiment, the unlocking member 160 is movably disposed on the first adapter seat 140 along the axis. The locking member 150 is movably disposed on the support frame 100, for example, slidably or rotatably disposed on the support frame 100 along the axis. The locking member 150 has a locking portion extending out of the support frame 100. The first adapter seat 140 is provided with a locking groove 141 that cooperates with the locking portion. There are two locking members 150, which are respectively arranged corresponding to the first position and the second position. The support frame 100 is correspondingly provided with an elastic member 151 (e.g., a spring) to drive the locking member 150 to reset. The unlocking member 160 has an operating portion 161 and a transmission portion 162 acting on the locking member 150. When a force is applied to the operating portion 160, the transmission portion 162 pushes the locking portion out of the locking groove 141, thereby releasing the lock. When the force is removed from the operating portion 160, the locking member 150 resets under the action of the elastic member 151.

[0066] like Figure 6 and Figure 8 As 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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 usage 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 this time, the stroller can be called a double-person riding mode.

[0072] See again Figure 1 and Figure 2 In one embodiment, the second adapter 200 is movably connected to the front leg assembly 110 and has a use position and a folded position. In the first use mode, the second adapter 200 is in the folded position. In the second use mode, the second adapter 200 is in the use position. The use position and the folded position differ at least in the height direction; for example, the use position is higher than the folded position, and the use position is further forward than the folded position, to avoid interference between the second carrier 180 and the first carrier 170. In the figure, the front leg assembly 110 also includes a crossbar 113 connected to the bottom of the two front leg posts. The crossbar 113 is a footrest. After installation, the first carrier 170 is positioned above the footrest. Viewed along the width direction, the second adapter 200 extends beyond the upper surface of the front leg assembly 110 in the use position. In the folded position, the second adapter 200 slides downwards without protruding from the upper surface of the front leg assembly 110, resulting in a simpler appearance and preventing unnecessary collisions between the user and the second adapter 200.

[0073] like Figure 9 This application provides an adapter installation structure, including a mounting base 210, an adapter movably disposed on the mounting base 210, and an adapter releasably coupled to the adapter. The adapter has a relative use position and a retracted position. The adapter can be referred to as the second adapter 200 of the above embodiment, and the adapter can be referred to as the second adapter 181 of the above embodiment.

[0074] like Figures 9-16 In one embodiment, the adapter mounting structure further includes a foolproof element 220. When the second adapter 200 is in the use position, it allows the second adapter 200 to engage with the second adapter 181. When the second adapter 200 is in the folded position, the foolproof element 220 prevents the second adapter 200 from engaging with the second adapter 181 in the folded position, thus avoiding incorrect installation that could cause interference between the first carrier 170 and the second carrier 180 and result in component damage.

[0075] In one embodiment, the foolproof element 220 is movably configured, having a blocking position that prevents the second adapter 200 from engaging with the second adapter 181, and a yielding position that allows the second adapter 200 to engage with the second adapter 181. Furthermore, the foolproof element 220 is linked to the second adapter 200; the foolproof element 220 is movably configured on the mounting base 210, and when the second adapter 200 switches between a use position and a retracted position, the foolproof element 220 simultaneously switches between the yielding position and the blocking position.

[0076] In one embodiment, the foolproof element 220 is rotatably or slidably mounted on the mounting base 210. The adapter mounting structure also includes an elastic element 230 for driving the foolproof element 220 back to the blocked position. Figure 16 In the middle, the foolproof component 220 is rotatably mounted on the mounting base 210, while the elastic component 230 is a spring that acts between the foolproof component 220 and the mounting base 210.

[0077] For ease of operation, the foolproof component 220 has a driving ramp 221. When the second adapter 200 moves from the retracted position to the use position, the second adapter 200 acts on the driving ramp 221 to drive the foolproof component 220 from the blocking position to the avoidance position. In one embodiment, the second adapter 200 has an avoidance opening 204. In the use position, the foolproof component 220 is aligned with the avoidance opening 204 and, under the action of the elastic member 230, extends out of the avoidance opening 204 to switch to the blocking position. When the second adapter 200 is in the retracted position, the foolproof component 220 is misaligned with the avoidance opening 204 and rotates under the action of the second adapter 200 to switch to the avoidance position, while simultaneously compressing the elastic member 230.

[0078] See Figures 13-15 In one embodiment, the second adapter 200 and the mounting base 210 are slidably engaged. Specifically, the second adapter 200 includes a base 201 and a engaging portion 202 arranged axially. The base 201 and the mounting base 210 are slidably engaged, and a groove 203 is formed between the base 201 and the engaging portion 202. After the second adapter 181 is engaged with the second adapter 200, it is at least partially placed in the groove 203, restricting the axial movement of the second carrier 180. A clearance opening 204 is arranged in the base 201. When the anti-fooling member 220 is in the blocking position, it extends out of the clearance opening 204 and into the groove 203.

[0079] In one embodiment, the base 201 of the second adapter 200 has a disc-shaped structure and an axial direction, and the slot 203 is an annular slot. When the second adapter 181 and the second adapter 200 are combined, they can rotate around this axis. The mounting base 210 has an oblong structure, and the base 201 has an oblong structure that matches the shape of the mounting base 210. In the folded position, the outer peripheries of the mounting base 210 and the base 201 are flush.

[0080] See also Figures 13-15 In one embodiment, the adapter mounting structure further includes a locking member (hereinafter referred to as the second locking member 250) that locks the second adapter 200 in the use position or the retracted position. The second locking member 250 is movably disposed on the second adapter 200, for example, by rotation or sliding. In the figure, the second locking member 250 is rotatably mounted on the base 201 of the second adapter 200 and has a second locking part 2501 and a second operating part 2502 located on both sides of the pivot. The mounting base 210 is provided with a second locking groove 2101 that mates with the second locking part 2501. The second locking member 250 is provided with a torsion spring at its own pivot position to keep the second locking part 2501 inserted into the second locking groove 2101; during the unlocking operation, pressing the second operating part 2502 causes the second locking part 2501 to pop up and exit the second locking groove 2101. In one embodiment, there are two second locking grooves 2101, corresponding to the use position and the retracted position, respectively.

[0081] like Figures 13-15 In another embodiment, the second locking groove 2101 is a single groove corresponding to the usage position. The adapter mounting structure also includes a third locking member 260 that locks the second adapter seat 200 in the retracted position. The third locking member 260 is rotatably or slidably mounted on the mounting base 210. The base 201 is provided with a third locking groove 2011 that cooperates with the third locking member 260. The mounting base 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 mounted in the mounting base 210, and the elastic member is a torsion spring. The second locking member 250 also has a second transmission part 2503 that drives the third locking member 260 out of the third locking groove 2011. In the retracted position, the second transmission part 2503 is aligned with the third locking groove 2011.

[0082] See Figure 17 and Figure 18This invention provides a stroller, including a support frame 100 and a support member 300 for a child to stand on. The support frame 100 is described in the previous embodiment and will not be repeated here. The support member 300 is movably connected to the rear leg assembly 120 and has a relatively forward first usage position and a relatively rearward second position. In actual use, the support member 300 can be adjusted to the optimal position according to the child's height, body size, and other factors. Alternatively, the position of the support member 300 can be adjusted according to different usage modes of the stroller. For example, in the first usage mode, the support member 300 is adjusted to the first usage position; when the stroller is in the second usage mode, the first support member 170 is positioned rearward, and the support member 300 is adjusted to the second usage position accordingly.

[0083] 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. In one embodiment, a wheel seat 124 is provided at the bottom of the rear foot rod 121, the rear wheel 122 is disposed on the wheel seat 124, and the transverse connector 123 is disposed between the two wheel seats 124. In some embodiments, there are one or more transverse connectors 123.

[0084] In some embodiments, the support member 300 can slide or flip in the front-to-back direction. For example, the support member 300 and the rear foot assembly 120 are rotatably connected, and in the first use position, the front faces up and is used for a child to stand on, while in the second use position, the back faces up and is used for a child to stand on.

[0085] For example Figure 19 and Figure 20 The rear foot assembly 120 is provided with a sliding seat 310. To improve the support strength of the bearing member 300, the rear foot assembly 120 is provided with a transverse support member 125. 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.

[0086] 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.

[0087] 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.

[0088] A second unlocking member 350 is slidably disposed on the lower part 330. The second unlocking member 350 is located between the two fourth locking members 340 and engages with their inclined surfaces. The sliding direction of the second unlocking member 350 is perpendicular to the transverse connecting member 123. The second unlocking member 350 has a driving part that protrudes from the bottom of the lower part 330.

[0089] In one embodiment, an elastic element 341, such as a spring, is provided between the two fourth locking members 340 to drive them to reset. An elastic element 351, such as a spring, is provided in the lower part 330 to act on the second unlocking member 350 to reset it. During unlocking, the operating drive unit drives the second unlocking member 350 to slide and compress the elastic element 351. The inclined plane drives the two fourth locking members 340 to slide closer and compress the elastic element 341, while releasing the action on the sliding seat 310. At this time, the position of the carrier member 300 can be adjusted. After adjusting to the desired position, the operating force on the drive unit is released. The second unlocking member 350 resets under the action of the elastic element 351. The two fourth locking members 340 reset under the drive of the elastic element 341 and extend into the fourth locking groove 311 or are at the end of the fourth locking member 340 to lock the carrier member 300.
