Technical Field

[0003] The present application relates to a child stroller and a riding carrier and an armrest assembly thereof. Background Art

[0004] Existing strollers for children can adjust the use state of the riding vehicle according to needs, for example, the riding vehicle can be adjusted to a seat position for children to sit up or a sleeping basket position for children to lie down. The seat plate and support frame of the riding vehicle are connected by a connecting rod mechanism, and the structure of the connecting rod mechanism is relatively complex.

[0005] Furthermore, the ride consists of a connected support frame and seat fabric. When the ride switches between a seat and a sleeping cot, the support frame moves the seat fabric, causing it to change shape. Consequently, when adjusting the ride's operating position, the linkage mechanism can easily interfere with the seat fabric, causing problems with its use.

[0006] When the ride-on vehicle is in the sleeper cot position, the seat fabric can be divided into a base fabric and a skirt. The base fabric is used to support a child in a reclining position, and the skirt extends upward from the periphery of the base fabric. When the ride-on vehicle is in the seat position, the shape of the skirt and base fabric changes with the shape of the support frame. The base fabric can be divided into a backrest area, a seat area, and a legrest area according to different functions. When the ride-on vehicle switches between use states, the backrest area or the legrest area will be subject to greater tension, which can easily interfere with the movement of the support frame and cause the ride-on vehicle to be improperly used.

The edge of the first pivot seat 213 can be provided with a cover 214 extending outward (more specifically, downward), and the cover 214 can be connected to the connecting arm 212 by a fastener 2092. The first pivot seat 213 and the cover 214 can be, but are not limited to, integrally formed parts. The first pivot seat 213 and the cover 214 can cover the notch 21202 of the accommodating groove 2120 so that the notch of the accommodating groove 2120 is not open. In some embodiments, the periphery of the first pivot seat 213 and the cover 214 can be embedded in the notch 21202.

[0102] Referring to FIG4 , the support frame 22 may, for example, be annular. The support frame 22 may include two support rods 221 disposed opposite each other on the left and right sides. The upper ends of the two support rods 221 may be connected by an upper U-shaped rod 2221, and the lower ends of the two support rods 221 may be connected by a lower U-shaped rod 2222. Each support rod 221 may be provided with a second pivot seat 223. Referring to FIG6 , each second pivot seat 223 may be pivotally connected to an adjacent first pivot seat 213 via a first pivot 2239, and the second pivot seat 223 and the first pivot seat 213 may be pivotable about a first pivot axis XX. In some embodiments, a columnar member 2139 may be provided at the pivot center of the first pivot seat 213. The columnar member 2139 may have a center hole 21390, and the first pivot 2239 may pass through the pivot center of the second pivot seat 223 and be connected to the center hole 21390. The center line of the first pivot shaft 2239 may form a first pivot axis XX of the first pivot seat 213 and the second pivot seat 223. Of course, the specific pivoting manner of the first pivot seat 213 and the second pivot seat 223 is not limited to the above examples.

[0103] Referring to FIG4 , to facilitate assembly of the support frame 22, each second pivot seat 223 may be provided with an upper sleeve portion 2231 and a lower sleeve portion 2232. Each support rod 221 may be divided into an upper tube 2211 and a lower tube 2212. The lower end of the upper tube 2211 may be sleeved with the upper sleeve portion 2231, and the upper end of the lower tube 2212 may be sleeved with the lower sleeve portion 2232. The upper tube 2211 and the upper U-shaped rod 2221 may be, but are not limited to, integrally formed. The lower end of the lower tube 2212 may be connected to the lower U-shaped rod 2222 via a rotating joint 2204, thereby allowing the lower U-shaped rod 2222 to rotate relative to the lower tube 2212 and be positioned at a desired position as needed. In some alternative embodiments, the lower tube 2212 and the lower U-shaped rod 2222 may be, but are not limited to, integrally formed.

[0104] After the riding vehicle 200 is mounted on the vehicle frame 100, the position of the first pivot seat 213 can be fixed. By adjusting the relative positions of the first pivot seat 213 and the second pivot seat 223, the riding vehicle 200 can have at least two working states.

[0105] Specifically, referring to Figure 5 , by adjusting the relative positions of the first pivot seat 213 and the second pivot seat 223 to tilt the support frame 22 at an appropriate angle relative to the horizontal plane, the ride vehicle 200 can be positioned in a seated position suitable for a child, and the armrest assembly 300 can be extended forward above the seat plate 21, forming an armrest position. The seat fabric 23 includes a first seat fabric 23001 positioned above the support plate 211 and a second seat fabric 23002 positioned below the support plate 211. The seat fabric 23 can change shape as the support frame 22 moves. The first seat fabric 23001 can serve as a backrest, while the second seat fabric 23002 can limit the rearward movement of a child's legs. Furthermore, when the ride vehicle 200 is in the seated position, the relative position of the lower U-shaped rod 2222 and the lower tube 2212 can be adjusted to position the lower U-shaped rod 2222 in a more suitable position for supporting a child's legs.

[0106] Referring to the perspective view of the stroller 1000 shown in FIG11 , by adjusting the relative positions of the first pivot seat 213 and the second pivot seat 223 , the support frame 22 can be arranged generally horizontally, and the ride vehicle 200 is placed in a sleeping box position suitable for a child to lie down. The seat fabric 23 can also be transformed into a sleeping box shape as the support frame 22 moves. Referring to the perspective views of the ride vehicle 200 shown in FIG12 and FIG13 , when the ride vehicle 200 is in the sleeping box position and removed from the frame 100, the ride vehicle 200 can be used as a sleeping box. The armrest assembly 300 can be transformed into a handle position to facilitate the user's movement of the ride vehicle 200.

[0107] In the first embodiment, the riding vehicle 200 can change its working state by changing the relative positions of the first pivot seat 213 and the second pivot seat 223, without using a complex connecting rod mechanism, and can avoid the problem of the connecting rod mechanism interfering with the seat cloth 23 when the riding vehicle 200 changes its working state.

[0108] 6 to 10 , the relative position of the first pivot seat 213 and the second pivot seat 223 can be locked by a first locking mechanism 201. The first locking mechanism 201 can have a locked state and a released state. When the first locking mechanism 201 is in the locked state, the relative position of the first pivot seat 213 and the second pivot seat 223 is locked and cannot rotate relative to each other, and the ride vehicle 200 can be fixed in a certain operating state (such as the seat state or the sleeping box state described above). When the first locking mechanism 201 is in the released state, the first pivot seat 213 and the second pivot seat 223 can rotate relative to each other, and the operating state of the ride vehicle 200 can be adjusted.

[0109] Referring to Figures 6 and 7 , the first pivot seat 213 may be circumferentially arranged with at least two first locking grooves 2131. That is, the at least two first locking grooves 2131 may be arranged on the first pivot seat 213 at predetermined angular intervals around the first pivot axis XX. The first locking mechanism 201 may include a first locking member 2011, a first elastic return member 2012, and a first release member 2013. The first locking member 2011 may slidably engage with the second pivot seat 223 to move between a first locked position and a first released position. The movement direction of the first locking member 2011 may be perpendicular to the first pivot axis XX. The first elastic return member 2012 may be configured to drive the first locking member 2011 toward the first locked position. The first release member 2013 may be configured to drive the first locking member 2011 toward the first released position.

[0110] Figure 9 shows a cross-sectional view taken along line UU of Figure 4 , showing the first locking mechanism 201 in a locked state. When the first locking mechanism 201 is locked, the first locking member 2011 is in a first locked position, engaging with one of the at least two first locking slots 2131. The first pivot seat 213 and the second pivot seat 223 are fixedly secured against relative rotation, allowing the ride 200 to be positioned in a specific operating state. In Figure 9 , the ride 200 is positioned in a seating position.

[0111] Figure 10 also shows the UU cross-sectional view of Figure 4 , showing the first locking mechanism 201 in the released state. When the first locking mechanism 201 is in the released state, the first locking member 2011 is in the first released position and disengaged from the first locking slot 2131. At this point, the first pivot seat 213 and the second pivot seat 223 can rotate relative to each other, allowing the user to adjust the operating state of the ride vehicle 200. When the ride vehicle 200 is adjusted to another operating state (such as the sleeping box state shown in Figure 11 ), the first locking member 2011 can be engaged with the corresponding first locking slot 2131.

[0112] It should be noted that although the first embodiment illustrates the riding vehicle 200 in two operating states: a seat state and a sleeping box state, it is understood that in actual applications, the riding vehicle 200 can also have other operating states by designing the number and position of the first locking slots 2131. For example, the riding vehicle 200 can have a semi-reclining state between the seat state and the sleeping box state.

[0113] Referring to Figures 6 to 10 , the first pivot seat 213 and the second pivot seat 223 define an accommodating cavity 2230 (see Figure 7 ), in which the first locking member 2011 can be accommodated without protruding relative to the accommodating cavity 2230. A first elongated hole 20110 can be provided in the center of the first locking member 2011, through which the first pivot shaft 2239 and the columnar member 2139 can pass. The first elongated hole 20110 can be used to limit the travel of the first locking member 2011. The first pivot seat 213 can be provided with at least two first locking grooves 2131 at positions corresponding to both ends of the first locking member 2011. When the first locking mechanism 201 is in the locked state, both ends of the first locking member 2011 can simultaneously engage with the corresponding first locking grooves 2131, thereby more reliably locking the relative positions of the first pivot seat 213 and the second pivot seat 223.

[0114] More specifically, the first end of the first locking member 2011 can be configured as a first engaging end 20111. The at least two first locking grooves 2131 can include at least two first sub-locking grooves 21311. The at least two first sub-locking grooves 21311 can be arranged sequentially in the circumferential direction. The first engaging end 20111 can selectively engage with one of the at least two first sub-locking grooves 21311.

[0115] Referring to Figure 6 , the wall of each first sub-locking groove 21311 may be provided with a protrusion 21301. The protrusion 21301 may extend parallel to the first pivot axis XX. In other words, the protrusion 21301 may extend parallel to the first pivot axis XX along the wall of the first sub-locking groove 21311, or the protrusion 21301 may extend perpendicular to the first pivot axis XX from the bottom of the first sub-locking groove 21311. Referring to Figure 7 , the first engaging end 20111 may be provided with a recess 20101 that mates with the protrusion 21301. Referring to Figure 9 , when the first engaging end 20111 is inserted into any of the first sub-locking grooves 21311, the protrusion 21301 and recess 20101 form a concave-convex fit. In this way, the contact area between the first engaging end 20111 and the first sub-locking groove 21311 is increased, and the relative positions of the first pivot seat 213 and the second pivot seat 223 can be locked more reliably.

[0116] 9 and 10 , by providing the protrusion 21301 and the groove 20101, two adjacent first sub-locking grooves 21311 can have overlapping portions 213110. This avoids the problem of inconvenient placement of the first sub-locking grooves 21311 due to the small pivot angle between the two positioning positions of the second pivot seat 223 relative to the first pivot seat 213. When the first engaging end 20111 engages with either of the two adjacent first sub-locking grooves 21311, the first engaging end 20111 can engage with the overlapping portions 213110. Of course, in some alternative embodiments, the two adjacent first sub-locking grooves 21311 can be separated from each other and have no overlapping portions.

[0117] Continuing with Figures 6 and 7, the second end of the first locking member 2011 can be configured as a second engaging end 20112. The second engaging end 20112 and the first engaging end 20111 can be located at opposite ends of the first locking member 2011. The first pivot axis XX can be located between the first engaging end 20111 and the second engaging end 20112. The at least two first locking grooves 2131 can include at least two second sub-locking grooves 21312, which can be arranged sequentially in a circumferential direction. The second engaging end 20112 can selectively engage with one of the at least two second sub-locking grooves 21312.

[0118] Continuing with Figures 6 and 7, the second engaging end 20112 can be provided with a second protrusion 20113 extending in a direction parallel to the first pivot axis XX. The second engaging end 20112 can engage with one of the second sub-locking grooves 21312 via the second protrusion 20113. The first pivot seat 213 can include a second limiting groove 21313. Each second sub-locking groove 21312 can communicate with a second limiting groove 21313. When the second protrusion 20113 of the second engaging end 20112 exits the second sub-locking groove 21312, it can enter the second limiting groove 21313. The walls of the second limiting groove 21313, by abutting against the second protrusion 20113, can limit the relative rotation range of the first pivot seat 213 and the second pivot seat 223. That is, the second limiting groove 21313 can be used as an angle limiting mechanism to limit the relative rotation range of the first pivot seat 213 and the second pivot seat 223. Of course, other angle limiting mechanisms can also be used to limit the relative rotation range of the first pivot seat 213 and the second pivot seat 223.

[0119] 6 , the second limiting groove 21313 may be, for example, fan-shaped, and each of the second sub-locking grooves 21312 may be communicated with the second limiting groove 21313 on the radial inner side of the second limiting groove 21313 .

[0120] In the ride vehicle 200 provided in this embodiment, when the first locking mechanism 201 is in the locked state, the first engaging end 20111 of the first locking member 2011 can selectively engage with one of the at least two first sub-locking grooves 21311, while the second engaging end 20112 can selectively engage with one of the at least two second sub-locking grooves 21312. This can more reliably lock the relative positions of the first pivot seat 213 and the second pivot seat 223. When the first locking mechanism 201 is in the unlocked state, the first engaging end 20111 can be withdrawn from the first sub-locking groove 21311, while the second engaging end 20112 can be withdrawn from the second sub-locking groove 21312. It will be understood that in other embodiments, the embodiments of the first engaging end 20111 and the first sub-locking groove 21311, and the second engaging end 20112 and the second sub-locking groove 21312 are not limited to the above examples. Both ends of the first locking member 2011 can selectively cooperate with the corresponding first locking grooves through the engaging ends, thereby achieving the purpose of more reliably locking the relative positions of the first pivot seat 213 and the second pivot seat 223 in the present application.

[0121] 9 and 10 , the first elastic return member 2012 can be located in the accommodating cavity 2230. The two ends of the first elastic return member 2012 can respectively abut against the first locking member 2011 and the second pivot seat 223. The first elastic return member 2012 can directly drive the first locking member 2011 to move toward the first locked position. Of course, in some alternative embodiments, the first elastic return member 2012 can indirectly drive the first locking member 2011 to move toward the first locked position.

[0122] FIG14 illustrates a cross-sectional view taken along line MM in FIG5 . Referring to FIG7 and FIG14 , a first release member 2013 may be mounted on the top of the support frame 22, more specifically, on the upper U-shaped bar 2221, away from the second pivot seat 223. The first locking mechanism 201 may further include a first cable 2014. The first release member 2013 may be operably connected to the first locking member 2011 via the first cable 2014. More specifically, referring to FIG14 , a first end of the first cable 2014 may be operably connected to the first release member 2013. Referring to FIG9 and FIG10 , a second end of the first cable 2014 may be connected to the first locking member 2011. In some embodiments, the first release member 2013 may be a knob, operably connected to the first end of the first cable 2014 via a centering structure 2015, as shown in FIG14 . When the first release member 2013 is subjected to a release force and rotates relative to the upper U-shaped rod 2221, the inclined surface 20151 of the central structure 2015 converts the rotation of the first release member 2013 into movement of the first cable 2014, which in turn pulls the first locking member 2011 toward the first release position. When the first release member 2013 is no longer subjected to the release force, the first elastic return member 2012 drives the first locking member 2011 toward the first lock position, while the first cable 2014, via the central structure 2015, drives the first release member 2013 back to its original position. The manner in which the first release member 2013 drives the first locking member 2011 to release is not limited to the above description. For example, in some alternative embodiments, the first release member 2013 may be a button that moves vertically or a push button that moves laterally.

[0123] 3 and 4 , the second locking mechanism 202 can have a locked state and a released state. When the engaging base 219 is engaged with the mounting base 19 and the second locking mechanism 202 is in the locked state, the second locking mechanism 202 can lock the engaging base 219 to the mounting base 19, preventing the engaging base 219 from accidentally detaching from the mounting base 19. When the engaging base 219 is engaged with the mounting base 19 and the second locking mechanism 202 is in the released state, the second locking mechanism 202 no longer locks the engaging base 219 to the mounting base 19, and the engaging base 219 can be removed from the mounting base 19.

[0124] 2 and 3 , the mounting seat 19 may have a first engaging recess 190, and the connecting seat 219 may engage with the first engaging recess 190. In some alternative embodiments, the first engaging recess may be provided on the connecting seat 219, and the mounting seat 19 may engage with the first engaging recess.

[0125] Referring to Figures 4, 6, and 7, the wall of the mounting base 219 may be provided with a first through-hole 2190 that communicates with the receiving groove 2120. The second locking mechanism 202 may include a second locking member 2021, a second elastic return member 2022, and a second release member 2023. The second locking member 2021 may slidably engage with the first through-hole 2190 to enable movement to a second locked position or a second released position. The movement direction of the second locking member 2021 may be parallel to the first pivot axis XX. The second elastic return member 2022 may be configured to drive the second locking member 2021 toward the second locked position. The second release member 2023 may be configured to drive the second locking member 2021 toward the second released position.

[0126] 3 , the wall of the first engaging recess 190 may be provided with an outwardly protruding stopper 191. When the engaging seat 219 is engaged with the mounting seat 19 and the second locking mechanism 202 is in the locked state, the second locking member 2021 may be in a second locked position. The second locking member 2021 may extend below the stopper 191 and abut against the stopper 191, thereby preventing the engaging seat 219 from being removed from the first engaging recess 190. When the engaging seat 219 is engaged with the mounting seat 19 and the second locking mechanism 202 is in the released state, the second locking member 2021 may be in a second released position. The second locking member 2021 may retract into the receiving groove 2120 and disengage from the stopper 191, allowing the engaging seat 219 to be removed from the first engaging recess 190.

[0127] In some alternative embodiments, the stopper 191 can be replaced with a second locking groove (not shown) that cooperates with the second locking member 2021. When the second locking mechanism 202 is in the locked state, the second locking member 2021 can be inserted into the second locking groove. When the second locking mechanism 202 is in the released state, the second locking member 2021 can be removed from the second locking groove. In some embodiments, the wall of the first engaging recess 190 can be provided with both the stopper 191 and the locking groove. When the second locking mechanism 202 is in the locked state, the second locking member 2021 can be inserted into the second locking groove and abut against the stopper 191 below the stopper 191.

[0128] 6 and 7 , the second release member 2023 may include a connecting portion 20231 and an operating portion 20232. The connecting portion 20231 may be located in the receiving slot 2120 and operably connected to the second locking member 2021. The receiving slot 2120 may have a second opening 21201 defined in its wall, and the operating portion 20232 may slidably engage with the second opening 21201. The operating portion 20232 may move perpendicularly to the movement of the second locking member 2021. When the operating portion 20232 is pushed by an external release force, it may drive the second release member 2023 to move toward the second release position via the connecting portion 20231.

[0129] Referring to FIG. 6 , the connecting portion 20231 of the second release member 2023 may be provided with a groove 202301. The wall of the receiving groove 2120 may be provided with a third protrusion 20202, which may extend into the groove 202301. The second elastic return member 2022 may be located in the groove 202301. One end of the second elastic return member 2022 may abut against the wall of the groove 202301, while the other end of the second elastic return member 2022 may abut against the third protrusion 20202. The connecting portion 20231 may be provided with a drive chute 202302, and the second locking member 2021 may be provided with a drive pin 2024, which may slidably engage with the drive chute 202302. In alternative embodiments, the positions of the drive chute 202302 and the drive pin 2024 on the connecting portion 20231 and the second locking member 2021 may be interchanged.

[0130] When the second release member 2023 is pushed and moved by an external release force, the second elastic return member 2022 is compressed and deformed, and the inclined wall of the driving chute 202302 pushes against the driving pin 2024. As the driving pin 2024 moves along the driving chute 202302, it drives the second locking member 2021 toward the second release position. When the second release member 2023 is no longer pushed by the external release force, the second elastic return member 2022 returns to its original position and simultaneously pushes the second release member 2023 back to its original position. During the return process of the second release member 2023, the inclined wall of the driving chute 202302 pushes against the driving pin 2024. As the driving pin 2024 moves along the driving chute 202302, it drives the second locking member 2021 toward the second lock position. In some examples of the present application, the direction of the external release force applied to the second release member 2023 coincides with the direction in which the ride vehicle 200 is lifted from the vehicle frame 100. In some alternative embodiments, the direction of the external releasing force applied to the second releasing member 2023 may be opposite to the direction of lifting the riding vehicle 200 from the vehicle frame 100 .

[0131] Referring to FIG. 2 , the second locking member 2021 may be provided with a sloped surface 20211. Referring to FIG. 3 , the limiting member 191 may be provided with a sloped surface 1911. When the engaging seat 219 is inserted into the first engaging recess 190 and the sloped surface 20211 abuts against the sloped surface 1911, the second locking member 2021 is forced to move toward the second unlocked position, and the engaging seat 219 can continue to move downward. After the second locking member 2021 passes over the limiting member 191, the second locking member 2021 automatically extends below the limiting member 191 to abut against the limiting member 191. In alternative embodiments, either the sloped surface 1911 of the limiting member 191 or the sloped surface 20211 of the second locking member 2021 may be provided.

[0132] Figures 15 and 16 show partial exploded views of the armrest assembly 300 from different directions. Figure 17 shows a cross-sectional view taken along line NN in Figure 5 , and Figure 18 shows a cross-sectional view taken along line YY in Figure 4 . Figure 19 shows a perspective view of the armrest assembly 300 with one end separated from the ride vehicle 200 and the other end connected to the ride vehicle 200. Figures 20 and 21 show cross-sectional views taken along line SS in Figure 19 , showing the armrest assembly 300 in different stages of opening. Figure 22 shows another perspective view of the armrest assembly 300 with one end separated from the ride vehicle 200 and the other end connected to the load-bearing vehicle 200.

[0133] 15 and 16 , the armrest assembly 300 may include a first connection seat 31, a second connection seat 32, a third connection seat 33, an armrest tube 34, a third locking mechanism 35, and a fourth locking mechanism 37. The structure of the armrest assembly 300 may be substantially bilaterally symmetrical.

[0134] The armrest tube 34 may be generally U-shaped. A third connecting seat 33 may be provided at each end of the armrest tube 34. Each third connecting seat 33 may be fixed to the armrest tube 34 and cannot move or rotate relative to the armrest tube 34. Each third connecting seat 33 may be pivotally connected to the second connecting seat 32 via a third pivot 393, and the center line of the third pivot 393 may form a third pivot axis PP. Each second connecting seat 32 may be pivotally connected to the first connecting seat 31 via a second pivot 392, and the center line of the second pivot 392 may form a second pivot axis CC. The third pivot 393 (i.e., the third pivot axis PP) and the second pivot 392 (i.e., the second pivot axis CC) may be arranged near opposite ends of the second connecting seat 32, and the third pivot axis PP may be perpendicular to the second pivot axis CC.

[0135] The first connecting base 31 can be used to be detachably connected to the support frame 22 of the riding vehicle 200. When the first connecting base 31 is installed on the riding vehicle 200, the fourth locking mechanism 37 can lock the armrest assembly 300 on the support frame 22 of the riding vehicle 200.

[0136] Referring to FIG. 15 , a second engaging recess 315 may be provided on one side of the first connecting base 31, and a concave cavity 316 may be provided on the other side of the first connecting base 31. A fourth locking mechanism 37 may be mounted on the first connecting base 31. The fourth locking mechanism 37 may include a fourth locking member 371 and a fourth elastic return member 372. The fourth locking member 371 may be mounted in the concave cavity 316 and pivotally connected to the first connecting base 31 via a pin 373. A fourth protrusion 3711 may be provided on the first end of the fourth locking member 371, and the fourth elastic return member 372 may be sandwiched between the second end of the fourth locking member 371 and the wall of the concave cavity 316 (in FIG. 15 , the fourth elastic return member 372 is obscured by the fourth locking member 371, so the fourth elastic return member 372 is shown in dashed lines). A second through hole 3710 may be provided on the wall of the concave cavity 316 at a position corresponding to the fourth protrusion 3711, so that the fourth protrusion 3711 can enter the second engaging recess 315 through the second through hole 3710.

[0137] 19 , the support frame 22 may include an engaging protrusion 225, which may be provided with a fourth locking groove 2250. When the second engaging recess 315 and the engaging protrusion 225 are engaged and the fourth locking mechanism 37 is in the locked state, the fourth protrusion 3711 can be inserted into the fourth locking groove 2250 under the push of the fourth elastic return member 372, thereby locking the first connecting base 31 to the support frame 22. When the second engaging recess 315 and the engaging protrusion 225 are engaged and the fourth locking mechanism 37 is in the released state, the second end of the fourth locking member 371 can be pressed, and the fourth protrusion 3711 can be withdrawn from the fourth locking groove 2250, thereby removing the first connecting base 31 from the support frame 22.

[0138] Continuing to refer to Figures 15 and 16, the second connecting seat 32 and the first connecting seat 31 can be pivotally connected via a second pivot 392, which allows the armrest tube 34 to rotate, for example, swing up and down, so that the armrest assembly 300 can be switched to different working states. The armrest assembly 300 can, for example, have an armrest state as shown in Figure 5 and a handle state as shown in Figure 12. As previously mentioned, when the riding vehicle 200 is in the seat state as shown in Figure 5, the armrest assembly 300 can be switched to the armrest state, at which point the armrest tube 34 can extend forward above the seat plate 21. When the riding vehicle 200 is in the sleeping box state as shown in Figure 12, the armrest assembly 300 can be switched to the handle state, at which point the armrest tube 34 can extend roughly in a direction perpendicular to the board surface of the seat plate 21.

[0139] The third locking mechanism 35 can be used to lock the relative position of the second connecting seat 32 and the first connecting seat 31, thereby fixing the armrest assembly 300 in a certain operating state. The third locking mechanism 35 can have a locked state and a released state. When the third locking mechanism 35 is in the locked state, the relative position of the second connecting seat 32 and the first connecting seat 31 is locked and cannot rotate relative to each other, and the armrest assembly 300 can be maintained in a certain operating state. When the third locking mechanism 35 is in the released state, the second connecting seat 32 and the first connecting seat 31 can rotate relative to each other about the second pivot 392, at which time the operating state of the armrest assembly 300 can be adjusted.

[0140] Continuing with Figures 15 and 16 , at least two third locking grooves 313 may be provided on the peripheral wall of the first connecting base 31. The at least two third locking grooves 313 may be arranged sequentially in the circumferential direction. The second connecting base 32 may be provided with a sliding groove 323. The sliding groove 323 may extend perpendicularly to the second pivot axis CC. A third locking mechanism 35 may be provided on the second connecting base 32. The third locking mechanism 35 may include a third locking member 351, a third elastic return member 352, and a third release member 353. The third locking member 351 may slidably engage with the sliding groove 323 to move perpendicularly to the second pivot axis CC to a third locked position or a third released position. The third elastic return member 352 may be used to drive the third locking member 351 toward the third locked position. The third release member 353 may be used to drive the third locking member 351 toward the third released position.

[0141] 17 and 18 , when the third locking mechanism 35 is in the locked state, the third locking member 351 is in the third locked position, engaging with one of the at least two third locking slots 313, preventing the first and second connecting seats 31 and 32 from rotating relative to each other, and positioning the armrest assembly 300 in a specific operating state. When the third locking mechanism 35 is in the released state, the third locking member 351 is in the third released position, withdrawing from the third locking slot 313, allowing the first and second connecting seats 31 and 32 to rotate relative to each other, allowing the user to switch the operating state of the armrest assembly 300 as needed.

[0142] It should be noted that although the armrest assembly 300 in this embodiment is described in two working states: the armrest state and the handle state, it can be understood that in actual application, by designing the number and position of the third locking groove 313, the armrest assembly 300 can also have other working states.

[0143] Referring to Figures 15 to 17 , a first opening 3231 may be provided on the wall of the sliding groove 323, through which the third release member 353 may be connected to the third locking member 351. A third elastic return member 352 may be provided in the sliding groove 323, with its ends abutting against the bottom of the sliding groove 323 and the third locking member 351, respectively. When a release force is applied to the third release member 353, it may move along the first opening 3231 while simultaneously driving the third locking member 351 toward a third release position. As the third locking member 351 moves toward the third release position, the third elastic return member 352 may be compressed. When the release force applied to the third release member 353 is removed, the third elastic return member 352 may automatically return to its original position, simultaneously driving the third locking member 351 toward the third lock position.

[0144] The second connecting seat 32 may further be provided with a cover 326 , which may shield the third locking groove 313 that is not engaged with the third locking member 351 , so as to prevent the third locking groove 313 from being exposed.

[0145] Referring to Figure 15 , the third connecting seat 33 may be provided with a pivot slot 331. One end of the second connecting seat 32 may include a pivot joint 322 that is inserted into the pivot slot 331. The pivot joint 322 may be pivotally connected to the third connecting seat 33 via a third pivot shaft 393. The pivot joint 322 may be provided with a second elongated hole 3232. The third locking member 351 may be provided with a sliding pin 355. The sliding pin 355 may be parallel to the third pivot axis PP and may slidably engage with the second elongated hole 3232. The wall of the pivot slot 331 may be provided with a driving slot 333, into which the end of the sliding pin 355 may extend.

[0146] Referring to Figures 19-22 , when the first connection base 31 at one end of the armrest assembly 300 is disconnected from the support frame 22, the third connection base 33 at the other end of the armrest assembly 300 can rotate about the third pivot axis PP toward the opening direction. During this rotation, the sidewall 3331 of the drive slot 333 (the shape of the drive slot 333 is shown in dashed lines in Figures 17 , 20 , and 21 ) pushes the sliding pin 355 along the second elongated hole 3232, allowing the third locking member 351 to move to the third unlocked position and exit the third locking slot 313. The armrest tube 34, the third connection base 33, and the second connection base 32 can then move together about the second pivot axis CC to the stowed position shown in Figure 22 , facilitating the child's exit from the ride vehicle 200.

[0147] In some embodiments, when the first connection base 31 at one end of the armrest assembly 300 is disconnected from the support frame 22, the third connection base 33 at the other end of the armrest assembly 300 can rotate approximately 90 degrees in the opening direction about the third pivot axis PP (i.e., open outward 90 degrees), allowing the armrest assembly 300 to reach a fully open state. At this point, the third locking member 351 can move to a third unlocked position. The armrest tube 34, the third connection base 33, and the second connection base 32 can then rotate about the second pivot axis CC toward the support frame 22, allowing the armrest assembly 300 to move to the stowed state shown in FIG. 22 . In some embodiments, when the armrest assembly 300 is in the stowed state, the armrest assembly 300 can abut against the support frame 22.

[0148] In some embodiments not shown, the child stroller provided in the first embodiment of the present application may have the following variations, for example.

[0149] 1. The first locking member 2011 of the first locking mechanism 201 can be slidably engaged with the first pivot seat 213 and move between a first locked position and a second locked position in a direction perpendicular to the first pivot axis XX. A plurality of first locking slots that selectively engage with the first locking member 2011 can be provided on the second pivot seat 223.

[0150] Second, one of the two ends of the first locking member 2011 can serve as the engaging end, while the other end may not be used to engage with the first locking groove. In other words, the first locking member 2011 may have only one of the first engaging end and the second engaging end. Accordingly, only one of the first sub-locking groove 21311 and the second sub-locking groove 21312 may be provided.

[0151] Third, the structure of the first engaging end 20111 and the first sub-locking groove 21311 can be similar to the structure of the second engaging end 20112 and the second sub-locking groove 21312. That is, in a modified example (not shown), the first engaging end 20111 can be provided with a first protrusion. The structure of the first protrusion can be similar to that of the protrusion 21301, with only the position being changed. Therefore, the first protrusion can also be referred to as the first protrusion 21301. The first protrusion 21301 can protrude in a direction parallel to the first pivot axis XX and can be used to cooperate with the corresponding first sub-locking groove. In other words, in this case, the first protrusion 21301 of this modified example is formed by interchanging the positions of the groove 20101 of the first engaging end 20111 and the protrusion 21301 of the first sub-locking groove 21311, and at least two first sub-locking grooves can be connected to the first limiting groove of the first pivot seat 213. When the first protrusion 21301 exits from the corresponding first sub-locking groove, it can move into the first limiting groove.

[0152] Additionally, in some unillustrated embodiments, the structure of the second engaging end 20112 and the second sub-locking groove 21312 can be similar to that of the first engaging end 20111 and the first sub-locking groove 21311. Specifically, the wall of the second sub-locking groove can be provided with a protrusion that extends in a direction parallel to the first pivot axis XX. The second engaging end can be provided with a groove that mates with the protrusion. Furthermore, two adjacent second sub-locking grooves can have overlapping portions.

[0153] Fourth, the implementation of the first release member 2013 and the first elastic return member 2012 is not limited to the above examples; any implementation is sufficient as long as the first locking member 2011 can be controlled to extend into or out of the first locking slot 2131. For example, in some alternative embodiments, the first locking member 2011 can be directly connected to the first release member 2013, which can extend from the accommodating cavity 2230 for pressing. The first release member 2013 and the first locking member 2011 can be, but are not limited to, integrally formed. This allows for the omission of the first cable 2014, the centering structure 2015, and the like.

[0154] Fifth, the second locking mechanism 202 can be provided on the mounting base 19, and the second locking groove and / or the limiting member 191 can be provided on the engaging base 219. In this case, the engaging base 219, the connecting arm 212, and the first pivoting base 213 can be, for example, integrally formed. The implementation of the second release member and the second elastic return member is not limited to the above examples; any method can be used as long as the second locking member can be controlled to move between the second locked position and the second released position.

[0155] 6. The third connecting seat 33 can be omitted, and the second connecting seat 32 can be directly fixedly connected to the handrail tube 34. Under the action of the third locking mechanism 35, the handrail assembly 300 can still be switched to different working states.

[0156] 7. The positions of the third locking groove 313 and the third locking mechanism 35 on the first connecting seat 31 and the second connecting seat 32 can be interchanged. The implementation of the third locking mechanism 35 is not limited to the above example, as long as it can lock the relative position of the second connecting seat 32 and the first connecting seat 31.

[0157] 8. The positions of the second engaging recess 315 and the engaging protrusion 225 on the first connecting base 31 and the support frame 22 are interchangeable. The positions of the fourth locking mechanism 37 and the fourth locking groove 2250 on the first connecting base 31 and the support frame 22 are also interchangeable. Furthermore, the embodiment of the fourth locking mechanism 37 is not limited to the above example; any embodiment can be used as long as it can lock the first connecting base 31 and the support frame 22 together.

[0158] A child stroller 1000 according to a second embodiment of the present application will be described below with reference to FIG. 23 to FIG. 33 .

[0159] Figures 23 and 24 show a perspective view and a side view of a child stroller 1000 according to a second embodiment of the present application in a state of use. The child stroller may include a frame 100, a ride carrier 200, an armrest assembly 300, a canopy support assembly 400, and the like.

Figure 29 shows a partial rear view of the child stroller 1000 shown in Figure 28. Figures 30 to 32 show the structure of the ride carrier 200 in Figure 28 from different perspectives. In the child stroller 1000 shown in FIG33 , the riding carrier 200 is in a seat state, and the backrest area 2313 of the riding carrier 200 is at another tilt angle.

[0160] 23 to 25 , the ride vehicle 200 is detachably mounted to the vehicle frame 100. Of course, in some alternative embodiments, the ride vehicle 200 may be non-detachably connected to the vehicle frame 100. The armrest assembly 300 may be mounted to the ride vehicle 200. A canopy support assembly 400 may be mounted to the ride vehicle 200. The canopy support assembly 400 may include a tarpaulin 41 that can be deployed or retracted. In some alternative embodiments, the canopy support assembly 400 is not required.

[0161] Similar to the first embodiment, the frame 100 according to the second embodiment may also include a front support frame 11, a rear support frame 12, an upper support frame 13, a rider frame 14, a shock absorber frame 15, a storage rack 16, a wheel assembly 17, a mounting base 19, etc. The frame 100 may be foldable or non-foldable. The structure of the frame 100 may be substantially bilaterally symmetrical.

[0162] The front support frame 11 may include two front rods 111 and a front crossbar 112 connected between the two front rods 111. The front support frame 11 may be generally U-shaped. Due to the angle of the vehicle frame 100, the front crossbar 112 is not shown in Figures 23 and 24. For detailed structure of the front support frame 11, please refer to the above description of the front support frame 11 shown in Figures 1 to 3.

[0163] The front wheel of the wheel assembly 17 can be mounted on the front support frame 11. The rider frame 14 can include two rider bars 141 and a rider cross bar 142 connected between the two rider bars 141. The rider frame 14 can be generally U-shaped. The upper support frame 13 can include two upper bars 131. The lower ends of the two upper bars 131 can be connected to the upper ends of the two front bars 111, respectively. The upper ends of the two upper bars 131 can be connected to the lower ends of the two rider bars 141, respectively. The rear support frame 12 can include two rear bars 121 and a rear cross bar 122 connected between the two rear bars 121. The rear support frame 12 can be generally H-shaped. The rear wheel of the wheel assembly 17 can be mounted on the rear support frame 12. The upper ends of the two rear bars 121 can be connected to the two front bars 111, respectively. The shock absorbing frame 15 may include two shock absorbing rods 151 , the upper end of each shock absorbing rod 151 may be connected to the adjacent upper rod 131 , and the lower end of each shock absorbing rod 151 may be connected to the adjacent rear rod 121 on the same side.

[0164] The storage rack 16 may include two storage rods 161 and a storage cross bar 162 connected between the two storage rods 161. The storage rack 16 may be generally U-shaped. The middle portion of the storage rack 16 may be connected to the shock-absorbing rod 151 on the same side via a connecting rod 18. Since the frame 100 according to the second embodiment may also include a storage basket 165 provided on the storage rack 16, the storage rods 161 and the storage cross bar 162 are not shown in Figures 23 and 24 due to the obstruction of the storage basket 165. For the detailed structure of the storage rack 16, reference may be made to the relevant description of the storage rack 16 shown in Figures 1 to 3 as described above. In some embodiments, the frame 100 (specifically, the rear support frame 12) may be provided with a bilaterally symmetrical brake mechanism 123 as described in the first embodiment. Due to the obstruction of the storage basket 165, the brake mechanism 123 is not shown in Figures 23 and 24. In some embodiments, the brake mechanism 123 may be offset to one side of the frame 100 .

[0165] The left and right sides of the frame 100 may be provided with mounting seats 19, respectively, and each mounting seat 19 may be connected to the shock absorbing rod 151 or the upper rod 131. Of course, the embodiment of the frame 100 is not limited thereto.

[0166] 25 to 27 , the ride vehicle 200 may be provided with a snap-fit ​​seat 219 on each of its left and right sides. The snap-fit ​​seat 219 can be used to detachably snap-fit ​​with the mounting seat 19 of the vehicle frame 100. To avoid redundant description, the detailed structure of the mounting seat 19 and the snap-fit ​​seat 219 and the connection method therebetween will not be described in detail here. For details, please refer to the above description of the mounting seat 19 and the snap-fit ​​seat 219 shown in FIG. 1 to 7 .

[0167] The riding vehicle 200 can be installed on the vehicle frame 100 in the forward direction or in the rearward direction. In the second embodiment, the riding vehicle 200 is mainly described as being installed on the vehicle frame 100 in the rearward direction.

[0168] The following describes, with reference to Figures 23, 24, and 28, how the ride carrier 200 is mounted rearwardly on the frame 100. Referring to Figures 23 and 24, when the ride carrier 200 is in the sleeping box position, the end of the ride carrier 200 where the canopy support assembly 400 is located can be positioned away from the caregiver pushing the child stroller 1000 (i.e., away from the handlebar 14). Referring to Figure 28, when the ride carrier 200 is in the seat position, the child riding in the ride carrier 200 can face rearward in the direction of travel, facing the caregiver pushing the child stroller 1000.

[0169] Conversely, when the ride carrier 200 is mounted on the frame 100 in a forward-facing position, if the ride carrier 200 is in the sleeping box state, the end of the ride carrier 200 where the canopy support assembly 400 is located can be close to the caregiver pushing the child stroller 1000 (i.e., close to the handlebar 14). If the ride carrier 200 is in the seat state, the child riding in the ride carrier 200 can face forward in the direction of travel and turn their back to the caregiver pushing the child stroller 1000.

[0170] Similar to the first embodiment, in the second embodiment of the present application, the "front," "rear," "left," and "right" directions of the vehicle frame 100 are schematically indicated by arrows F1 and B1 in FIG. 23 , and the "left" and "right" directions of the vehicle frame 100 are schematically indicated by arrows L1 and R1, respectively, based on the "front," "rear," "left," and "right" directions of the vehicle frame 100. Depending on the orientation of the vehicle frame 100, the front, rear, and left directions of the vehicle frame 100 can be the same as or opposite to those of the vehicle frame 100. Specifically, referring to FIG. 23 , FIG. 24 , and FIG. 28 , when the vehicle frame 100 is mounted rearward on the vehicle frame 100, the front, rear, and left directions of the vehicle frame 100 can be opposite to those of the vehicle frame 100. Furthermore, in FIG. 25 to FIG. 27 , arrows F2 and B2 schematically indicate the "front," "rear," and arrows L2 and R2 schematically indicate the "left," and "right" directions of the vehicle frame 100. It is understood that when the ride vehicle 200 is mounted on the vehicle frame 100 in a forward orientation, the ride vehicle 200 can be positioned in the same front, rear, left, and right directions as the vehicle frame 100. The "front," "rear," "left," and "right" directions of the ride vehicle 200 are hereinafter indicated by arrows F2, B2, L2, and R2.

[0171] The seat plate 21 may include a support plate 211. The support plate 211 may be a plate made of plastic. Referring to Figure 28, when the ride vehicle 200 is in a seat state, the support plate 211 can be used to support the child's buttocks. Connecting arms 212 may be provided on the left and right sides of the support plate 211, respectively, and the connecting arms 212 may extend upward from the support plate 211. In some embodiments, the connecting arms 212 and the support plate 211 may be separate parts, and the two may be fixedly connected together. In some embodiments, the connecting arms 212 and the support plate 211 may be integrally formed parts. The upper ends of each connecting arm 212 may be respectively provided with a first pivot seat 213 as described in the first embodiment. In order to avoid redundant description, the specific structure of the first pivot seat 213 is not shown in Figures 22 to 33, and the detailed structure of the first pivot seat 213 can refer to the relevant description of the first pivot seat 213 according to the first embodiment.

[0172] The connecting arm 212 can be a one-piece structure or can be composed of multiple components. The connecting arm 212 in Figure 25 can be composed of multiple components, including an L-shaped member 2121, a centering member 2122, and a base 2123. The two perpendicular plates of the L-shaped member 2121 can be fixedly connected to the support plate 211 and the centering member 2122, respectively, and the centering member 2122 is connected to the base 2123. The snap-fit ​​seat 219 can be set on the base 2123. The snap-fit ​​seat 219 and the base 2123 can be, but are not limited to, integrally formed. The first pivot seat 213 can be set at the upper end of the base 2123. The first pivot seat 213 and the base 2123 can be, but are not limited to, integrally formed. The connecting arm 212 of the second embodiment can be composed of multiple components, and multiple models of centering members 2122 can be provided, so that the model of the centering member 2122 can be replaced as needed, thereby improving the adaptability of the support plate 211 and the base 2123. Of course, the implementation of the connecting arm 212 is not limited to the above examples.

[0173] Referring to Figure 26 , the support frame 22 can be, for example, annular in shape and can also be referred to as a surrounding frame. The seat fabric 23 can include a base fabric 231 and a surrounding frame 232. The surrounding frame 232 can be connected between the periphery of the base fabric 231 and the support frame 22. More specifically, the upper edge of the surrounding frame 232 can be sleeved onto the support frame 22. The base fabric 231 can be connected to the lower edge of the surrounding frame 232, sealing the bottom opening of the surrounding frame 232.

[0174] The support frame 22 may include two support rods 221 arranged opposite to each other on the left and right sides. Each support rod 221 may be respectively provided with a second pivot seat 223 as described in the first embodiment. The second pivot seat 223 can be pivotally connected to the first pivot seat 213 on the same side and the second pivot seat 223 and the first pivot seat 213 can pivot around a first pivot axis XX, and the first pivot axis XX can extend in the left-right direction. When the riding vehicle 200 is installed on the vehicle frame 100, the positions of the seat plate 21 and the first pivot seat 213 can be fixed. When the support frame 22 is subjected to an external pivoting force, the support frame 22 and the second pivot seat 223 can rotate relative to the first pivot seat 213 around the first pivot axis XX, that is, the support frame 22 can rotate relative to the seat plate 21 around the first pivot axis XX, so that the riding vehicle 200 can be switched to a sleeping box state or a seat state.

[0175] In some embodiments, considering the situation when a child is sitting in the ride vehicle 200, the center of gravity of the support plate 211 may be offset forward relative to the first pivot axis XX. Of course, in some alternative embodiments, the center of gravity of the support plate 211 may be substantially directly below the first pivot axis XX, or the center of gravity of the support plate 211 may be offset backward relative to the first pivot axis XX.

[0176] Referring to Figures 24 to 26 , when the ride vehicle 200 is in the sleeping box position, the support frame 22 can be arranged generally horizontally, the enclosure 232 can be extended downward and fully deployed, and the base fabric 231 can be suspended below the support frame 22 via the enclosure 232. The support plate 211 can support the base fabric 231 below the base fabric 231. The base fabric 231 provides a relatively flat support surface for the child to lie down. Furthermore, when the ride vehicle 200 is in the sleeping box position and removed from the vehicle frame 100, the ride vehicle 200 can be used independently. The armrest assembly 300 can be switched to a carry handle position to facilitate the user's movement of the ride vehicle 200.

[0177] Referring to Figures 28 and 30 , when the ride vehicle 200 is in the seat position, the seat pan 21 remains stationary, while the support frame 22 can rotate relative to the seat pan 21, assuming an inclined position. The shapes of the enclosure 232 and base fabric 231 can be modified to define a space for a child to sit. Furthermore, the armrest assembly 300 can pivot relative to the support frame 22 to an armrest position. In this position, the armrest assembly 300 extends forward above the seat pan 21.

[0178] As in the first embodiment, the circumferential relative positions of the first pivot seat 213 and the second pivot seat 223 in the second embodiment can be locked by the first locking mechanism 201. The first locking mechanism 201 can have a locked state and a released state. When the first locking mechanism 201 is in the locked state, the relative positions of the first pivot seat 213 and the second pivot seat 223 can be locked and cannot rotate relative to each other, and the riding vehicle 200 can be fixed in the seat state or the sleeping box state. When the first locking mechanism 201 is in the released state, the first pivot seat 213 and the second pivot seat 223 can rotate relative to each other, and the riding vehicle 200 can switch between the sleeping box state and the seat state. In order to avoid redundant description, the specific structure of the first locking mechanism 201 will not be repeated here, and can be understood with reference to the above description of the first locking mechanism 201 of the first embodiment.

[0179] Referring to Figures 26 and 27, as well as Figures 31 and 32, depending on the function of the ride vehicle 200 in the seating position, the base fabric 231 of the seat fabric 23 may include, in sequence, a leg rest area 2311, a seat area 2312, and a back rest area 2313. The seat area 2312 and the leg rest area 2311 may be separated by a first stitch or a first fold line 231a. The seat area 2312 and the back rest area 2313 may be separated by a second stitch or a second fold line 231b. When the ride vehicle 200 switches between the seating position and the sleeping box position, the leg rest area 2311 and the back rest area 2313 may each pivot relative to the seat area 2312.

[0180] As previously mentioned, when the ride vehicle 200 is in the sleeping box position, the base fabric 231 can extend generally horizontally, and the leg rest area 2311, seat area 2312, and backrest area 2313 can cooperate to form a support surface for a child to lie down. The support plate 211 can support the base fabric 231 from below to improve its flatness. When the ride vehicle 200 is switched to the seat position, the backrest area 2313 can pivot upward relative to the seat area 2312, tending to pull the seat area 2312 backward.

[0181] When the ride vehicle 200 is in the seating position, the seating area 2312 can substantially cover the support plate 211 located below the seating area 2312, and the support plate 211 can support the seating area 2312. The backrest area 2313 can be tilted upward relative to the seating area 2312 and away from the support plate 211. The legrest area 2311 can be tilted downward relative to the seating area 2312 and away from the support plate 211. The seating area 2312 can be used to contact a child's buttocks, the backrest area 2313 can be used to support the child's back, and the legrest area 2311 can be used to support the child's legs.

[0182] In some embodiments, the leg rest area 2311 can be configured with a first hard board (not shown in the figure), the size of which can, for example, substantially match the size of the leg rest area 2311. The backrest area 2313 can be configured with a second hard board (not shown in the figure), the size of which can, for example, substantially match the size of the backrest area 2313. The seat area 2312 can be made of a flexible material without a hard board. When the ride vehicle 200 is in the sleeping box state, at least a portion of the seat area 2312 can be supported by the support board 211. The first hard board, the support board 211, and the second hard board can work together to provide a relatively flat support surface for the child.

[0183] In some embodiments not shown, the legrest area 2311 may include, for example, an upper fabric layer and a lower fabric layer, with a first receiving cavity defined between the upper and lower fabric layers. The first rigid board, for example, may be a rigid plastic board, which can be inserted into the first receiving cavity. A cushioning layer may also be provided in the first receiving cavity, for example, located above the first rigid board. The seating area 2312 may also include an upper fabric layer and a lower fabric layer, with a cushioning layer interposed between the upper and lower fabric layers. The backrest area 2313 may have a similar layered structure to the legrest area 2311, similarly including an upper fabric layer and a lower fabric layer, with a second receiving cavity defined between the upper and lower fabric layers. The second rigid board, for example, may be a rigid plastic board, which can be inserted into the second receiving cavity. A cushioning layer may be provided in the second receiving cavity, for example, located above the second rigid board. Furthermore, the upper and / or lower fabric layers of the legrest area 2311, seating area 2312, and backrest area 2313 may themselves have certain cushioning properties.

[0184] 26 and 27 , when the ride vehicle 200 is in the sleeping box state, the front side of the seating area 2312 may extend forward from the front edge of the support plate 211, and the rear edge of the seating area 2312 may be located between the front edge 2111 and the rear edge 2112 of the support plate 211. That is, the boundary between the seating area 2312 and the leg rest area 2311 (the first seam or first fold line 231a) may be located forward of the front edge 2111 of the support plate 211, and the boundary between the seating area 2312 and the backrest area 2313 (the second seam or second fold line 231b) may be located between the front edge 2111 and the rear edge 2112 of the support plate 211. The boundary between the seating area 2312 and the backrest area 2313 may, for example, be close to the center of gravity of the support plate 211.

[0185] 32 , when the ride vehicle 200 switches from the sleeping box state to the seat state, the seat area 2312 can be pulled by the backrest area 2313 to move rearward relative to the support plate 211, so that the front edge of the seat area 2312 (corresponding to the first seam line or first fold line 231a) approaches the front edge 2111 of the support plate 211, and the rear edge of the seat area 2312 (corresponding to the second seam line or second fold line 231b) approaches the rear edge 2112 of the support plate 211. The seat area 2312 can substantially cover the support plate 211.

[0186] When the riding vehicle 200 switches from the seat state to the sleeping box state, the seat area 2312 can be pulled forward so that the seat area 2312 can move forward relative to the support plate 211 to the state of Figure 27, and the base fabric 231 and the enclosure 232 can be unfolded to the ideal state.

[0187] When the riding vehicle 200 of the embodiment of the present application switches between the sleeping box state and the seat state, the seat area 2312 can move forward and backward relative to the support plate 211, which can effectively avoid the problem of excessive local tension in the seat cloth 23 (especially the excessive tension between the seat area 2312 and the backrest area 2313) interfering with the movement of the support frame 22, and can effectively avoid the riding vehicle 200 from being used improperly.

[0188] Furthermore, the seating area 2312 can be made of a flexible material rather than a rigid panel. This allows the legrest area 2311 and backrest area 2313 to pivot relative to the seating area 2312 without having to pivot about a fixed pivot axis. This allows the seat fabric 23 to deform more freely during the transition between states of the ride vehicle 200, making it less susceptible to localized excessive tension. Of course, in alternative embodiments, the seating area 2312 can also be configured with a rigid panel.

[0189] 31 and 32 , the ride 200 may further include a belt restraint system 26. The belt restraint system 26 may include a crotch strap 261 and two shoulder straps 262. One end of the crotch strap 261 may be connected to a seat portion 2312, and the other end of the crotch strap 261 may be detachably connected to one end of each of the two shoulder straps 262. The other end of each of the two shoulder straps 262 may be connected to a backrest portion 2313. In some embodiments, the backrest portion 2313 may be provided with a plurality of adjustment holes 23130. The other ends of the two shoulder straps 262 may be selectively engaged with one of the plurality of adjustment holes 23130 to adjust the belt restraint system 26 to the child's body size.

[0190] 27, 29, and 32, the ride vehicle 200 may further include a traction mechanism 27, and the backrest area 2313 may be connected to the seat area 2312 via the traction mechanism 27. When the ride vehicle 200 switches from the sleeping box state to the seat state, the traction mechanism 27 and the backrest area 2313 together may pull the seat area 2312 backward.

[0191] In some embodiments, when the ride vehicle 200 switches from a sleeping box state to a seat state, the backrest area 2313 can apply an upward traction force to the seat area 2312, and the traction mechanism 27 can apply a downward traction force to the seat area 2312 to facilitate the seat area 2312 to move backward generally horizontally along the support plate 211.

[0192] In some embodiments, the support plate 211 may be provided with two through-holes 2110, which may be arranged symmetrically. The traction mechanism 27 may, for example, include two symmetrically arranged adjustment straps 271. The first end 2711 of each adjustment strap 271 may be connected to the back of the seat area 2312, for example, by sewing. The second end 2712 of each adjustment strap 271 may pass through the corresponding through-hole 2110 from top to bottom, then extend rearward to connect to the back of the backrest area 2313. The second end of the adjustment strap 271 may be connected to the backrest area 2313, for example, by sewing. Alternatively, the back of the backrest area 2313 may be connected to a connecting buckle 29 via a webbing 291, and the second end 2712 of each adjustment strap 271 may be connected to the connecting buckle 29. The connecting buckle 29 may be a Japanese buckle or other buckle. The second end 2712 of the adjustment strap 271 may be detachably connected to the connecting buckle 29, for example. In some embodiments, the length of the adjustment strap 271 is adjustable.

[0193] When the ride vehicle 200 switches from the sleeping box state to the seat state, the backrest area 2313 can apply a force to the seat area 2312 from above the support plate 211 to move it backward. The adjustment strap 271 can be tightened and apply a force to the seat area 2312 from below the support plate 211 to move it backward. This helps the seat area 2312 move backward against the support plate 211 and prevents it from tilting upward relative to the support plate 211. After the ride vehicle 200 switches to the seat state, the tightened adjustment strap 271 can also be used to maintain the relative position of the seat area 2312 and the support plate 211.

[0194] 27 and 32 , the through hole 2110 may be close to the rear edge of the support plate 211. In this way, when the ride vehicle 200 is in the sleeping box state, the length of the adjustment strap 271 exposed relative to the support plate 211 may be shorter.

[0195] The first end 2711 of the adjustment strap 271 may be close to the boundary between the seat area 2312 and the backrest area 2313. In this way, when the ride vehicle 200 is in the seat state, the adjustment strap 271 may pull the seat area 2312 downward near the rear edge of the seat area 2312, thereby offsetting the upward pulling force exerted by the backrest area 2313 on the rear edge of the seat area 2312.

[0196] Of course, the embodiments of the traction mechanism 27 are not limited to the above examples. For example, in some alternative embodiments, the number of through-holes 2110 on the support plate 211 can be one, three, or more. When there is only one through-hole 2110, it can be centered in the left-right direction. When there are multiple through-holes 2110, they can be symmetrically arranged in the left-right direction. Accordingly, the traction mechanism 27 can include one, three, or more adjustment straps 271.

[0197] 30 , 32 and 33 , the seat fabric 23 may further include a backrest adjustment mechanism 28 . When the ride vehicle 200 is in the seating position, the backrest adjustment mechanism 28 may be used to adjust the inclination angle of the backrest area 2313 relative to the seat area 2312 .

[0198] The backrest adjustment mechanism 28 may include two connecting straps 281 and a lock 282. The lock 282 may be located on the back of the backrest area 2313. The first ends 2811 of the two connecting straps 281 may be connected to the two support rods 221, respectively. The second ends 2812 of the two connecting straps 281 may extend along the enclosure 232 to the back of the backrest area 2313 (the side facing away from the child) and then connect to the lock 282. In some embodiments, the second ends 2812 of the two connecting straps 281 may extend through the lock 282. By adjusting the length between the first end 2811 of each connecting strap 281 and the lock 282, the tilt angle of the backrest area 2313 relative to the seat area 2312 can be adjusted. The longer the length between the first end 2811 of each connecting strap 281 and the lock 282, the smaller the tilt angle of the backrest area 2313 relative to the seat area 2312, making the backrest area 2313 more suitable for lying flat. The shorter the length between the first end 2811 of each connecting strap 281 and the lock 282 , the greater the inclination angle of the backrest area 2313 relative to the seat area 2312 , and the closer the backrest area 2313 is to being upright.

[0199] The lock 282 may be a one-way lock. When the one-way lock is locked, the second end 2812 of each connecting strap 281 can be pulled to shorten the distance between the first end 2811 of each connecting strap 281 and the lock 282. When the distance between the first end 2811 of each connecting strap 281 and the lock 282 needs to be increased, the one-way lock needs to be switched to the unlocked state.

[0200] The enclosure 232 and / or the backrest area 2313 may be provided with a guide structure that can be used to guide the extension direction of each connecting strap 281. Referring to FIG. 29 , the guide structure may, for example, include a channel 2320 provided in the enclosure 232 and a channel 2321 provided in the backrest area 2313. The channel 2320 may, for example, be formed within the enclosure 232. The channel 2321 may, for example, be defined by the backside of the backrest area 2313 and a strip 23131 provided on the backside of the backrest area 2313.

[0201] A ride vehicle 200 according to a third embodiment of the present application will be described below with reference to FIG. 34 .

[0202] FIG34 shows a bottom perspective view of a ride vehicle 200 provided in a third embodiment of the present application. Unless otherwise specified, the structure of the ride vehicle 200 may refer to that described in the second embodiment. The following primarily describes the differences between the third embodiment and the second embodiment.

[0203] 34 , the seat fabric 23 may include a first cover sheet 237 positioned below the base fabric 231. The first cover sheet 237 and the base fabric 231 may define a first pocket structure 239 for accommodating the support plate 211. The first pocket structure 239 may have first side openings 23701 on its left and right sides for the connecting arms 212 to extend from. In some embodiments, the first pocket structure 239 may accommodate at least one adjustment strap 271. In some embodiments, the first pocket structure 239 may have a rear opening 23702 on its rear side for the at least one adjustment strap 271 to extend from.

[0204] In some embodiments, the front edge 2371 of the first covering sheet 237 can be secured to the back surface (the side facing away from the child) of the base fabric 231 by sewing, for example. The location of the sewing between the front edge 2371 and the base fabric 231 can be close to the boundary between the seat area 2312 and the leg rest area 2311. The rear edge 2372 of the first covering sheet 237 can be secured to the back surface of the backrest area 2313 by sewing. In some embodiments, the front edge 2371 of the first covering sheet 237 does not need to be sewn to the back surface of the base fabric 231; the first covering sheet 237 only needs to be able to shield the support plate 211.

[0205] The first covering sheet 237 may be a fabric sheet or other types of sheets. By shielding the support plate 211 with the first covering sheet 237 , the appearance consistency of the ride vehicle 200 may be improved.

[0206] A ride vehicle 200 according to a fourth embodiment of the present application will be described below with reference to FIG. 35 and FIG. 36 .

[0207] Figures 35 and 36 show a bottom view and a side view of a ride vehicle 200 provided in a fourth embodiment of the present application. Unless otherwise specified, the structure of the ride vehicle 200 may refer to that described in the second embodiment. The following primarily describes the differences between this fourth embodiment and the second embodiment.

[0208] In this fourth embodiment, the adjustment strap 271 and connecting buckle 29 of the second embodiment are omitted. Accordingly, the support plate 211 can omit the through-hole 2110 through which the adjustment strap 271 passes. A second covering sheet 273 can be provided beneath the base fabric 231, serving as the traction mechanism 27.

[0209] Specifically, a front edge 2731 of the second cover sheet 273 may be connected to the front edge of the seat area 2312, and a rear edge 2732 of the second cover sheet 273 may be connected to the backrest area 2313. The second cover sheet 273 and the base fabric 231 may define a second pocket structure 2730 for accommodating the support plate 211. The second pocket structure 2730 may have second side openings 27301 on its left and right sides for the connecting arms 212 to extend out of.

[0210] When the ride vehicle 200 switches from the sleeping box state to the seat state, the backrest area 2313 can apply a force to the seat area 2312 from above the support plate 211 to move it backward, and the second cover sheet 273 can be tightened and apply a force to the seat area 2312 from below the support plate 211 to move it backward. The second pocket structure 2730 can guide the relative movement between the support plate 211 and the seat area 2312.

[0211] In some embodiments, the left and right sides of the second covering sheet 273 can be connected to the seat fabric 23 (e.g., the seat area 2312) by sewing or other means. Thus, when the ride vehicle 200 switches from the sleeping box state to the seat state, the connection between the left and right sides of the second covering sheet 273 and the seat fabric 23 can effectively prevent the seat area 2312 from moving left and right relative to the support plate 211, thereby facilitating a more uniform rearward force on the seat area 2312 in the front-to-back direction, thereby ensuring smoother movement of the seat area 2312.

[0212] 36 , when the ride vehicle 200 is in the seat state, the support plate 211 and the second pocket structure 2730 may cooperate to limit the rearward movement of the seating area 2312 relative to the support plate 211. More specifically, the support plate 211 may abut against the front end of the second pocket structure 2730.

[0213] A riding vehicle 200 according to a fifth embodiment of the present application will be described below with reference to FIG. 37 .

[0214] FIG37 shows a bottom view of a ride vehicle 200 provided in a fifth embodiment of the present application. Unless otherwise specified, the structure of the ride vehicle 200 may refer to that described in the fourth embodiment. The following primarily describes the differences between the fifth embodiment and the fourth embodiment.

[0215] 37 , the rear edge 2732 of the second cover sheet 273 can be connected to the back of the backrest area 2313 via at least one connecting strap 274. When the ride vehicle 200 is in the sleeping box state, the rear edge 2732 of the second cover sheet 273 can, for example, be close to the rear edge 2112 of the support plate 211. In some embodiments, the length of the connecting strap 274 can be adjusted.

[0216] A riding vehicle 200 according to a sixth embodiment of the present application will be described below with reference to FIG. 38 .

[0217] FIG38 shows a side view of a ride vehicle 200 according to a sixth embodiment of the present application. Unless otherwise specified, the structure of the ride vehicle 200 may refer to that described in the second embodiment. The following primarily describes the differences between the sixth embodiment and the second embodiment.

[0218] Referring to FIG. 38 , in this sixth embodiment, the connecting arm 212 can be a one-piece structure. For example, the connecting arm 212 can be an integrally formed part formed by injection molding. The engaging seat 219 can be directly formed on the connecting arm 212, thereby being integrally formed with the connecting arm 212. For example, the first pivot seat 213 can be disposed at the upper end of the connecting arm 212.

[0219] In some embodiments, the connecting arm 212 may also be an integral structure with the support plate 211. The connecting arm 212 and the support plate 211 may be integrally formed, for example, by injection molding, so that the connecting arm 212 and the support plate 211 can be connected together without using any other fastening structure.

[0220] In some embodiments, the structure of each connecting arm 212 can be generally symmetrical front-to-back, forming a front-to-back symmetry plane S. The front-to-back symmetry plane S of the two connecting arms 212 can generally pass through the center of gravity of the support plate 211. In one embodiment of the present application, the front-to-back symmetry plane S can generally pass through the first pivot axis XX. This helps stabilize the center of gravity of the seat plate 21. In some embodiments, the front-to-back symmetry plane S of each connecting arm 212 can be generally perpendicular to the surface of the support plate 211.

[0221] A ride vehicle 200 according to a seventh embodiment of the present application will be described below with reference to FIG. 39 to FIG. 42 .

[0222] Figures 39 and 40 show side views of a ride vehicle 200 according to the seventh embodiment of the present application from different perspectives. The ride vehicle 200 is in a sleeping box configuration, and Figure 40 omits the tarpaulin 41 and seat fabric 23. Figures 41 and 42 show perspective views of the seat panel 21 from Figures 39 and 40 from different perspectives. Unless otherwise specified, the structure of the ride vehicle 200 can be referenced to that described in the sixth embodiment. The following primarily describes the differences between this seventh embodiment and the sixth embodiment.

[0223] Referring to Figures 39 to 41 , the seat panel 21 may be provided with a protruding structure 218 to prevent it from being placed flat. The protruding structure 218 may, for example, be provided on the bottom surface of the seat panel 21. When the ride vehicle 200 is removed from the vehicle frame 100, the protruding structure 218 prevents the seat panel 21 from being stably placed flat on the plane H, as shown in Figure 39 . Therefore, in some embodiments of the present application, the protruding structure 218 may also be referred to as an anti-misuse structure.

[0224] As shown in FIG39 , the protruding structure 218 may protrude downward from the bottom surface of the seat panel 21. More specifically, the protruding structure 218 may, for example, protrude downward from the bottom surface of the support plate 211. When the ride vehicle 200 is placed on a plane H, the protruding structure 218 may initially contact the plane H. However, the protruding structure 218 itself cannot stably support the ride vehicle 200 on the plane H, causing the ride vehicle 200 to become unbalanced and prone to rocking and tilting, which may also cause the bottom surface of the seat panel 21 to contact the plane H.

[0225] In this embodiment, the protruding structure 218 is provided to prevent the riding vehicle 200 from being tilted and unstable when placed on a plane H. This serves to remind the user not to leave an infant or young child alone in the riding vehicle 200 in a sleeping position on the plane H, thereby eliminating safety hazards. Furthermore, the protruding structure 218 serves to remind the user not to place the riding vehicle 200 alone on the plane H, thereby preventing the front end 2301 or rear end 2302 of the seat fabric 23 from contacting the plane H.

[0226] 39 to 41 , exemplary embodiments of the protruding structure 218 are shown. The protruding structure 218 may extend from the center region of the bottom surface of the support plate 211 toward the edge region of the support plate 211. The protruding structure 218 may generally have an arched shape (or arc shape) with a high center and low ends.

[0227] More specifically, in this embodiment, the protruding structure 218 can be located roughly in the middle of the bottom surface of the support plate 211 and can extend in the left-right direction. The protruding structure 218 can generally have an arched shape, with a higher center and lower left and right sides. That is, the distance between the center of the protruding structure 218 and the bottom surface of the support plate 211 can be greater, while the distance between the left and right sides of the protruding structure 218 and the bottom surface of the support plate 211 can be smaller. When the ride vehicle 200 is placed on a plane H, even if the protruding structure 218 and the bottom surface of the seat plate 21 are simultaneously in contact with the plane H, the ride vehicle 200 can still easily wobble in the front-to-back and left-to-right directions.

[0228] Referring to Figures 41 and 42, the protruding structure 218 can, for example, be integrally formed with the seat plate 21 (more specifically, the support plate 211). The protruding structure 218 can also enhance the structural strength and load-bearing capacity of the seat plate 21. In some embodiments, the protruding structure 218 can be formed with an upwardly opening inner cavity 2180, and a reinforcing rib 2182 can be provided in the inner cavity 2180. This enhances the structural strength of the seat plate 21 without excessively increasing its weight. Of course, in some alternative embodiments, the protruding structure 218 and the seat plate 21 can be separate components that can be mounted together using a suitable structure.

[0229] Alternatively, in some alternative embodiments, the protruding structure 218 may extend along the front-to-back direction or the diagonal direction of the support plate 211 .

[0230] Referring again to Figures 39 and 41 , in some embodiments, the bottom surface of the support plate 211 may be provided with a guide surface 2115. The guide surface 2115 may be located behind the through hole 2110, for example, adjacent to the rear edge of the through hole 2110. The guide surface 2115 may slidably engage with the adjustment strap 271 and serve to guide the adjustment strap 271 away from the support plate 211. The guide surface 2115 may be convex, more specifically, arc-shaped. The shape of the guide surface 2115 is designed to facilitate sliding of the adjustment strap 271 while minimizing wear on the adjustment strap 271.

[0231] Referring again to Figure 39 , when the ride vehicle 200 of this embodiment is in the sleeping box position, the support plate 211 can be tilted relative to the support frame 22. More specifically, in the sleeping box position, the distance between the front end of the support plate 211 and the support frame 22 can be smaller than the distance between the rear end of the support plate 211 and the support frame 22. When the ride vehicle 200 is mounted on the vehicle frame 100 and switched to the seat position, the support plate 211 can be tilted at a certain angle relative to the horizontal plane, allowing children to comfortably ride in the ride vehicle 200.

[0232] The following will describe a ride vehicle 200 according to an eighth embodiment of the present application with reference to FIG. 43 and FIG. 44 .

[0233] FIG43 shows a side view of a ride vehicle according to an eighth embodiment of the present application, and FIG44 shows a perspective view of the seat panel in FIG43 . Unless otherwise specified, the structure of the ride vehicle 200 may refer to that described in the seventh embodiment. The following primarily describes the differences between the eighth embodiment and the seventh embodiment.

[0234] Referring to Figures 43 and 44 , in this embodiment, the protruding structure 218 can be located generally in the middle of the bottom surface of the support plate 211 and can extend in the front-to-back direction. The protruding structure 218 can generally have an arched shape (or arc shape) with a higher center and lower front and rear ends. That is, the distance between the middle portion of the protruding structure 218 and the bottom surface of the support plate 211 can be larger, while the distance between the front and rear ends of the protruding structure 218 and the bottom surface of the support plate 211 can be smaller. When the ride vehicle 200 is placed on plane H, even if the protruding structure 218 and the bottom surface of the seat plate 21 can be in contact with plane H at the same time, the ride vehicle 200 is still prone to shaking in the front-to-back and left-to-right directions.

[0235] Referring to Figure 44 , the protruding structure 218 can be a separate structure from the seat plate 21. The protruding structure 218 can be secured to the bottom surface of the support plate 211 via a connector 2181. In some embodiments, the connector 2181 can be L-shaped. The two perpendicular plates 21811 and 21812 of the L-shaped connector 2181 can be fixedly connected to the protruding structure 218 and the support plate 211, respectively, via fasteners 2183. The number of connectors 2181 can be set as needed.

[0236] In some alternative embodiments, the protruding structure 218 can be mounted on the bottom surface of the seat plate 21 using other suitable structures. For example, the protruding structure 218 can have a skirt (or flange) through which multiple fasteners (e.g., screws) pass to connect to the support plate 211. Furthermore, in some alternative embodiments, a split protruding structure 218 can extend left-right or diagonally along the support plate 211, which is also within the scope of protection of this application.

[0237] A ride vehicle 200 according to a ninth embodiment of the present application will be described below with reference to FIG. 45 to FIG. 50 .

[0238] Figures 45 and 46 show perspective views of a ride vehicle 200 according to a ninth embodiment of the present application from two different perspectives. Unless otherwise specified, the structure of the ride vehicle 200 may refer to the description of the eighth embodiment. The following primarily describes the differences between the ninth embodiment and the eighth embodiment.

[0239] 45 and 46 , the ride vehicle 200 may be a deformable ride vehicle 200 that can switch between a seat state and a sleeping cot state as described in the eighth embodiment, or may be a non-deformable ride vehicle 200 that only has a sleeping cot state. In some examples of the present application, the ride vehicle 200 may include a sleeping cot body 201A and an anti-misuse structure 202A. In some examples of the present application, the anti-misuse structure 202A may be a protruding structure 218A. The sleeping cot body 201A may include a support frame 22, a seat plate 21, and a seat cloth 23 provided between the support frame 22 and the seat plate 21. The seat plate 21 may include a support plate 211 and connecting arms 212 provided on the left and right sides of the support plate 211, respectively. If the ride vehicle 200 is a deformable ride vehicle 200 capable of switching between a seat state and a cot state as described in the eighth embodiment, the support plate 211 may be a plate-like structure that covers only the middle portion of the bottom of the ride vehicle 200 and is used only to support the child's buttocks, as shown in FIG. 44 of the eighth embodiment. If the ride vehicle 200 is a non-deformable ride vehicle 200 capable only of a cot state, the support plate 211 may be a plate-like structure that covers the entire bottom of the ride vehicle 200 and is used to support the child's entire body.

[0240] The following description uses the example of a non-deformable ride vehicle 200 that only has a sleeping cot state, i.e., the support plate 211 can be a rectangular plate-like structure that covers the entire bottom of the ride vehicle 200. Of course, in other embodiments, the support plate 211 can also be a plate-like structure of other shapes. As shown in Figures 45 and 46, in some examples of the present application, the protruding structure 218A can be an arc-shaped rod 218A fixed to the bottom surface of the seat plate 21. In some examples of the present application, the arc-shaped rod 218A can be located roughly in the middle of the bottom surface of the support plate 211 and extend in the front-to-back direction. The arc-shaped rod 218A is convexly curved in a direction away from the seat plate 21, i.e., the middle portion of the arc-shaped rod 218A is at a greater distance from the bottom surface of the support plate 211, while the front and rear ends of the arc-shaped rod 218A are at a smaller distance from the bottom surface of the support plate 211. When the ride vehicle 200 is placed on a plane (not shown in the drawings), even if the protruding structure 218A and the bottom surface of the seat plate 21 are in contact with the plane H at the same time, the ride vehicle 200 is still prone to shaking in the front-to-back and left-to-right directions.

[0241] As shown in Figures 45 and 46, the curved rod 218A may be, for example, a separate structure from the support plate 211. The front and rear ends of the curved rod 218A may be respectively connected to two connecting rods 220A. In some examples of the present application, the curved rod 218A and the two connecting rods 220A may be an integrally formed structure. In other embodiments, the curved rod 218A and the two connecting rods 220A may be a separate structure, and the curved rod 218A and the two connecting rods 220A may be connected by, for example, welding or fasteners 25. The two connecting rods 220A may be fixed to the back of the support plate 211 by fasteners 25 such as screws. In some examples of the present application, the seat cloth 23 may completely cover the bottom surface of the support plate 211, so that fasteners 25 such as screws can pass through the seat cloth 23 covering the bottom surface of the support plate 211 and be fixed to the back of the support plate 211. In other embodiments, if the seat cloth 23 does not completely cover the bottom surface of the support plate 211 , the fasteners 25 such as screws may also be directly fixed to the back surface of the support plate 211 .

[0242] In some alternative embodiments, the curved rod 218A can be located approximately in the middle of the bottom surface of the support plate 211 and extend in a left-right direction or a diagonal direction. In short, if the projection of the curved rod 218A on the seat plate 21 can roughly pass through the geometric center of the support plate 211 (i.e., the intersection of the two diagonals of the support plate 211), it will effectively prevent the ride vehicle 200 from lying flat. Of course, in some embodiments, the projection of the curved rod 218A on the seat plate 21 can also deviate from the geometric center of the support plate 211.

[0243] In addition, when the riding vehicle 200 can be a deformable riding vehicle 200 that can switch between a seat state and a sleeping basket state as described in the eighth embodiment, the arc rod 218A can, for example, be roughly located in the middle of the bottom surface of the support plate 211 and extend in the left and right directions, and the two ends of the arc rod 218A can be fixed to the support plate 211 respectively through the connecting rod 220A; or, the arc rod 218A can also be roughly located in the middle of the bottom surface of the support plate 211 and extend in the front and rear directions, and the two ends of the arc rod 218A can be fixed to the leg support area 2311 and the back support area 2313 of the seat cloth 23 respectively through the connecting rod 220A.

[0244] Of course, there are many other possible implementations of the protruding structure 218A, not limited to the examples described above. The number of protruding structures 218A provided is also not limited to the number in this embodiment, as long as the ride vehicle 200 can be supported unstably on the plane H. For example, in some embodiments not shown, the protruding structure 218A can also be a corrugated tube fixed to the bottom surface of the support plate 211. In some embodiments, as shown in Figures 47 and 48, the protruding structure can also be a spherical cap-shaped structure 218B that protrudes downward from the geometric center of the bottom surface of the support plate 211 (i.e., the intersection of the two diagonals of the support plate 211). The spherical cap-shaped structure can have a skirt (or flange) 220B. Multiple fasteners 25 (e.g., screws) can pass through the skirt 220B and connect to the support plate 211. In other embodiments, the spherical cap-shaped structure 218B can also be arranged offset from the geometric center of the support plate 211. In other embodiments, as shown in Figures 49 and 50, the protruding structure can also be an inverted tapered structure 218C, projecting downward from the geometric center of the bottom surface of the support plate 211 (i.e., the intersection of two diagonals of the support plate 211). The inverted tapered structure 218C has a skirt 220C (or flange), through which a plurality of fasteners 25 (e.g., screws) pass to connect to the support plate 211. In other embodiments, the inverted tapered structure 218C can also be positioned offset from the geometric center of the support plate 211.

[0245] The following will describe a ride vehicle 200 according to a tenth embodiment of the present application with reference to FIG. 51 and FIG. 52 .

[0246] FIG51 shows a perspective view of a ride vehicle 200 according to the tenth embodiment of the present application. FIG52 schematically illustrates a schematic diagram of the structure of an anti-misuse structure 202A in the ride vehicle 200 according to the tenth embodiment of the present application. Unless otherwise specified, the structure of the ride vehicle 200 may refer to the description of the ninth embodiment. The following primarily describes the differences between the tenth embodiment and the ninth embodiment.

[0247] 51 and 52 , in some examples of the present application, the anti-misuse structure 202A may be approximately located at the geometric center of the bottom surface of the support plate 211 (i.e., the intersection of the two diagonals of the support plate 211). Of course, in other embodiments, the anti-misuse structure 202A may also deviate from the geometric center of the bottom surface of the support plate 211. Specifically, the anti-misuse structure 202A may include a fixing seat 2181D, a push button 2182D, an alarm 2183D, and a fifth elastic reset member 2184D. The fixing seat 2181D may be fixed to the geometric center of the bottom surface of the support plate 211. The fixing seat 2181D may partially protrude from the bottom surface of the support plate 211, or it may be flush with the bottom surface of the support plate 211. The sleeping cot body 201A may enclose a storage space 2010A for accommodating children. In embodiments where the fixing seat 2181D is flush with the bottom surface of the support plate 211, the fixing seat 2181D may be completely embedded in the support plate 211, or may be partially embedded in the support plate 211 and partially located in the accommodation space 2010A. In some examples of the present application, the fixing seat 2181D may be flush with the bottom surface of the support plate 211, and partially embedded in the support plate 211 and partially located in the accommodation space 2010A. A soft cushion with grooves (not shown in the drawings) may be provided in the accommodation space 2010A to avoid the fixing seat 2181D and improve the comfort of the child. The push button 2182D is movably disposed on the fixing seat 2181D and protrudes from the bottom surface of the fixing seat 2181D. In some examples of the present application, the fixing seat 2181D may be a substantially cylindrical structure, and the fixing seat 2181D may have a mounting hole 21811D, which may be a blind hole. A first limiting protrusion 21812D may be provided around the edge of the hole wall of the mounting hole 21811D.

[0248] In some examples of the present application, referring to Figures 51 and 52, a push button 2182D may include a hemispherical button body 21821D, a second limiting protrusion 21822D disposed around the edge of the button body 21821D, and a push post 21823D fixed to the concave surface of the button body 21821D. When the push button 2182D is mounted on the fixing base 2181D, the second limiting protrusion 21822D of the push button 2182D may be located within the mounting hole 21811D and abut against the top of the first limiting protrusion 21812D. The cooperation between the first limiting protrusion 21812D and the second limiting protrusion 21822D prevents the push button 2182D from being dislodged from the fixing base 2181D. When the push button 2182D is mounted on the fixing base 2181D, the spherical surface of the button body 21821D may protrude downward. The push button 2182D is switchable between a first position and a second position. When the push button 2182D is in the first position, the button body 21821D of the push button 2182D may at least partially protrude from the fixing base 2181D, or in other words, from the bottom surface of the support plate 211, and the push post 21823D may be spaced apart from the alarm 2183D. When the push button 2182D is in the second position, the button body 21821D may move toward the bottom of the mounting hole 21811D, and the push post 21823D may push the alarm 2183D.

[0249] Further, referring to FIG52 , the alarm 2183D can be disposed in the fixing seat 2181D, specifically fixed to the top wall of the mounting hole 21811D, and the alarm 2183D can be adapted to be pushed to sound an alarm. In some examples of the present application, when the push button 2182D is in the second position, the push column 21823D of the push button 2182D can push the alarm 2183D so that the alarm 2183D sounds an alarm, thereby reminding the caregiver to avoid placing the ride vehicle 200 flat on a flat surface such as the ground. The alarm 2183D can, for example, be an alarm 2183D that can emit an audible and visual reminder signal, or it can be an alarm 2183D that can send an alarm message to the caregiver's mobile communication device, etc. In short, as long as a warning function can be provided, it will suffice.

[0250] Further, referring to Figure 51, a fifth elastic return member 2184D can be abutted between the fixed seat 2181D and the push button 2182D, and the fifth elastic return member 2184D can be adapted to apply force to the push button 2182D to move it to the second position. In some examples of the present application, two fifth elastic return members 2184D may be provided. Both fifth elastic return members 2184D can be springs and respectively located on either side of the push column 21823D. Taking one of the fifth elastic return members 2184D as an example, one end of the fifth elastic return member 2184D can abut against the top wall of the mounting hole 21811D, and the other end can abut against one end of the concave surface of the button body 21821D. By providing two fifth elastic return members 2184D to abut against the left and right ends of the button body 21821D, the movement of the button body 21821D can be made smoother.

[0251] 23 , 51 , and 52 , when the ride carrier 200 is mounted on the child stroller, the push button 2182D disposed on the support plate 211 is suspended in the air. Therefore, the push button 2182D is held in the first position by the elastic force of the fifth elastic return member 2184D, and the push post 21823D of the push button 2182D is spaced apart from the alarm 2183D. When the ride carrier 200 is removed from the child stroller and placed on a flat surface, such as the ground, the button body 21821D of the push button 2182D is pushed by the surface toward the top wall of the mounting hole 21811D to the second position. The push post 21823D of the push button 2182D pushes against the alarm 2183D, causing it to sound an alarm, reminding the caregiver not to place the ride carrier 200 on a flat surface.

[0252] The following will describe a ride vehicle 200 according to an eleventh embodiment of the present application with reference to FIG. 53 to FIG. 58 .

[0253] Figures 53 and 54 show a top perspective view and a side perspective view of the riding vehicle 200 provided in the eleventh embodiment of the present application. Figure 55 shows a partially enlarged view of the riding vehicle 200 provided in the eleventh embodiment of the present application, and Figure 56 shows a schematic structural diagram of the riding vehicle 200 provided in the eleventh embodiment of the present application after omitting the seat cloth 23 and the tarpaulin 41; Figure 57 shows a partially enlarged view of a riding vehicle in the prior art; and Figure 58 shows a schematic structural diagram of a riding vehicle in the prior art after omitting the seat cloth and the tarpaulin. In the absence of conflict, the structure of the riding vehicle 200 can refer to the description in the tenth embodiment. The following mainly describes the differences between this eleventh embodiment and the tenth embodiment.

[0254] 53 and 54 , in some examples of the present application, the ride vehicle 200 may include a support frame 22, a seat panel 21, and a seat cloth 23. The support frame 22 may be a rectangular ring-shaped frame structure. The seat panel 21 may be spaced apart from the support frame 22 and may be used to support a child. In some examples of the present application, the seat panel 21 may include only a support panel 211, without including connecting arms 212 provided on the left and right sides of the support panel 211, respectively. That is, in some examples of the present application, the seat panel 21 and the support panel 211 may be the same component. Similarly, when the ride vehicle 200 may be a deformable ride vehicle 200 capable of switching between a seat state and a sleeping cot state as described in the eighth embodiment, the support panel 211 may be a plate-like structure that only covers the middle portion of the bottom of the ride vehicle 200, as shown in FIG. 44 of the eighth embodiment, and is only used to support the child's buttocks. When the ride vehicle 200 is a non-deformable ride vehicle 200 that only has a sleeping cot state, the support plate 211 can be a plate-like structure that covers the entire bottom of the ride vehicle 200 and can be used to support the child's entire body. Opposite sides of the support frame 22 can be provided with respective snap-fitting seats 219 that can be snap-fitted with the mounting seats 19 of the vehicle frame 100. In some examples of the present application, the two snap-fitting seats 219 can be specifically provided on either side of the long side of the support frame 22. The seat cloth 23 can be wrapped between the support frame 22 and the seat plate 21, that is, the support frame 22 and the support plate 211 can be softly connected only by the seat cloth 23, as shown in Figures 55 and 56. In the prior art, for example, a rigid connector 24 as shown in Figures 57 and 58 is often provided between the support frame 22 and the support plate 211, or the support frame 22 and the support plate 211 are connected by a connecting arm 212 and a snap-fitting seat 219. In some examples of the present application, the support frame 22 and the support plate 211 are softly connected only by the seat cloth 23, so that the seat cloth 23 can be switched between an expanded state and a folded state to form an anti-misuse structure 202A. Please note that although the description of the prior art herein uses similar or identical reference numerals to those in the present application for elements having functions and structures similar to those in the present application, the use of such similar or identical reference numerals is for illustrative purposes only and does not constitute an improper limitation on the specific features of the various embodiments of the present application.

[0255] In other examples, the support frame 22 may also be an annular frame structure of other shapes, such as a circular or elliptical annular frame structure, and the support plate 211 may correspondingly be configured as a circular or elliptical plate structure.

[0256] When the ride carrier 200 is attached to the mounting base 19 of the stroller frame 100 via the left and right snap-fit ​​mounts 219, the mounting base 19 exerts an upward force on the snap-fit ​​mounts 219, while the weight of the child lying in the accommodating space 2010A exerts a downward force on the seat pan 21. This forces the support frame 22 and seat pan 21 to move relatively apart, thereby placing the seat fabric 23 in an unfolded state. When the ride carrier 200 is removed from the stroller frame 100, the upward force exerted by the mounting base 19 on the snap-fit ​​mounts 219 and the downward force exerted by the child's weight on the seat pan 21 are lost. As a result, the support frame 22 and seat pan 21 move relatively close together, placing the seat fabric 23 in a collapsed state. This means that the entire ride carrier 200 collapses and becomes unusable. This prevents the ride carrier 200 from being placed on a flat surface.

[0257] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0258] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
