Description

Technical Field

[0001] This utility model relates to a children's stroller and its riding vehicle and armrest assembly. Background Technology

[0002] Existing strollers designed for children's travel can be adjusted to different configurations as needed, such as a seat for a child to sit upright or a bassinet for a child to lie down. The seat and support frame are connected by a linkage mechanism, which has a relatively complex structure.

[0003] In addition, the vehicle includes a connected support frame and a seat cover. When the vehicle switches between a seated position and a bassinet position, the support frame moves the seat cover, changing its shape. Therefore, when adjusting the vehicle's usage state, the linkage mechanism can easily interfere with the seat cover, causing malfunctions.

[0004] When the vehicle is in bassinet mode, the seat cover consists of a base and a surround. The base supports the child in a reclining position, while the surround extends upwards from the perimeter of the base. When the vehicle is in seat mode, the shape of the surround and base changes with the shape of the support frame. The base can be divided into a backrest area, a seat area, and a leg rest area, depending on its function. During the switching between these modes, the backrest area or leg rest area experiences significant tension, which can easily interfere with the movement of the support frame, leading to malfunctions in the vehicle.

The upper ends of the two support members 221 can be connected by an upper U-shaped rod 2221, and the lower ends of the two support members 221 can be connected by a lower U-shaped rod 2222. Each support member 221 is provided with a second pivot seat 223. See also... Figure 6 Each second pivot seat 223 is pivotally connected to an adjacent first pivot seat 213 via a first pivot 2239, and both the second pivot seat 223 and the first pivot seat 213 are pivotable about a first pivot axis XX. In some embodiments, a cylindrical member 2139 is provided at the pivot center of the first pivot seat 213, the cylindrical member 2139 having a central hole 21390, and the first pivot 2239 passes through the pivot center of the second pivot seat 223 and connects to the central hole 21390. The centerline of the first pivot 2239 forms the first pivot axis XX of the first pivot seat 213 and the second pivot seat 223. Of course, the specific pivoting method of the first pivot seat 213 and the second pivot seat 223 is not limited to the examples above.

[0104] See Figure 4To facilitate the 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 is sleeved with the upper sleeve portion 2231, and the upper end of the lower tube 2212 is 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 parts. The lower end of the lower tube 2212 can 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 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 parts.

[0105] After the passenger vehicle 200 is installed on the frame 100, the position of the first pivot 213 is fixed. By adjusting the relative positions of the first pivot 213 and the second pivot 223, the passenger vehicle 200 can have at least two operating states.

[0106] Specifically, see Figure 5 By adjusting the relative positions of the first pivot seat 213 and the second pivot seat 223, the support frame 22 is tilted at a suitable angle relative to the horizontal plane, and the riding vehicle 200 is in a seated state suitable for a child's sitting posture. The armrest assembly 300 extends forward above the seat plate 21 and is in an armrest state. The seat fabric 23 may include a first seat fabric 23001 located above the support plate 211 and a second seat fabric 23002 located below the support plate 211. The seat fabric 23 changes shape as the support frame 22 moves. The first seat fabric 23001 can be used as a backrest, and the second seat fabric 23002 can restrict the rearward range of motion of the child's legs. In addition, when the riding vehicle 200 is in the seated state, the relative position of the lower U-shaped bar 2222 and the lower tube 2212 can be adjusted so that the lower U-shaped bar 2222 is in a position more suitable for supporting the child's legs.

[0107] See Figure 11 The perspective view of the stroller 1000 shown illustrates how adjusting the relative positions of the first pivot 213 and the second pivot 223 allows the support frame 22 to be arranged substantially horizontally, positioning the riding vehicle 200 in a sleeping box state suitable for a child to lie down. The seat cover 23 also changes into a sleeping box shape as the support frame 22 moves. See also... Figure 12 The three-dimensional view of the vehicle 200 shown and Figure 13 The perspective view of the riding vehicle 200 shown indicates that the riding vehicle 200 can be used as a sleeping box when it is in the sleeping box state and removed from the frame 100. The armrest assembly 300 can be changed to a handle state to facilitate the user's movement of the riding vehicle 200.

[0108] In the first embodiment, the passenger vehicle 200 can change its working state by changing the relative position of the first pivot 213 and the second pivot 223, without the need for a complex linkage mechanism, and also avoids the problem of the linkage mechanism interfering with the seat fabric 23 when the passenger vehicle 200 changes its working state.

[0109] See Figures 6 to 10 The relative positions of the first pivot seat 213 and the second pivot seat 223 are locked by the first locking mechanism 201. The first locking mechanism 201 has a locked state and an unlocked 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 are locked and cannot be rotated relative to each other, and the vehicle 200 is fixed in a certain working state (as described above, the seat state or the sleeping box state). When the first locking mechanism 201 is in the unlocked state, the first pivot seat 213 and the second pivot seat 223 can rotate relative to each other, and the working state of the vehicle 200 can be adjusted at this time.

[0110] See Figure 6 and Figure 7 At least two first locking slots 2131 are arranged sequentially along the circumferential direction on the first pivot seat 213. That is, at least two first locking slots 2131 are arranged at preset angular intervals around the first pivot axis XX on the first pivot seat 213. The first locking mechanism 201 includes a first locking member 2011, a first elastic reset member 2012, and a first unlocking member 2013. The first locking member 2011 is slidably engaged with the second pivot seat 223 to move between a first locked position and a first unlocked position. The direction of movement of the first locking member 2011 is perpendicular to the first pivot axis XX. The first elastic reset member 2012 is used to drive the first locking member 2011 to move towards the first locked position. The first unlocking member 2013 is used to drive the first locking member 2011 to move towards the first unlocked position.

[0111] Figure 9 It shows Figure 4 The UU cross-sectional view shows the first locking mechanism 201 in a locked state. When the first locking mechanism 201 is in the locked state, the first locking member 2011 is in a first locked position, and the first locking member 2011 engages with one of at least two first locking slots 2131. The first pivot seat 213 and the second pivot seat 223 cannot rotate relative to each other, and the vehicle 200 is positioned in a certain working state. Figure 9 The passenger vehicle 200 is positioned in the seat position.

[0112] Figure 10 Similarly, it is shown Figure 4The UU cross-sectional view shows the first locking mechanism 201 in the unlocked state. When the first locking mechanism 201 is in the unlocked state, the first locking member 2011 is in the first unlocked position and separated from the first locking groove 2131. At this time, the first pivot seat 213 and the second pivot seat 223 can rotate relative to each other, and the user can adjust the working state of the vehicle 200. When the vehicle 200 is adjusted to another working state (e.g., Figure 11 After the sleeping box state is shown, the first locking member 2011 can be engaged with the corresponding other first locking groove 2131.

[0113] It should be noted that although the first embodiment describes the vehicle 200 in two working states: a seat state and a sleeping box state, it is understood that in practical applications, the vehicle 200 can also have other working states by designing the number and position of the first locking slots 2131. For example, the vehicle 200 can have a semi-reclining state between the seat state and the sleeping box state.

[0114] See Figures 6 to 10 The first pivot 213 and the second pivot 223 define the receiving cavity 2230 (see Figure 7 The first locking member 2011 is accommodated in the receiving cavity 2230 without protruding relative to the receiving cavity 2230. A first elongated hole 20110 is provided in the middle of the first locking member 2011, through which the first pivot 2239 and the cylindrical member 2139 pass. The first elongated hole 20110 can be used to limit the travel of the first locking member 2011. At least two first locking grooves 2131 are provided at each end of the first pivot seat 213 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 simultaneously engage with the corresponding first locking grooves 2131, thus more reliably locking the relative positions of the first pivot seat 213 and the second pivot seat 223.

[0115] More specifically, the first end of the first locking member 2011 is configured as a first engaging end 20111. At least two first locking slots 2131 include at least two first sub-locking slots 21311, which are arranged sequentially in the circumferential direction. The first engaging end 20111 selectively engages with one of the at least two first sub-locking slots 21311.

[0116] See Figure 6Each first sub-locking groove 21311 has a protrusion 21301 on its wall, the protrusion 21301 extending in a direction parallel to the first pivot axis XX. In other words, the protrusion 21301 can extend along the wall of the first sub-locking groove 21311 in a direction parallel to the first pivot axis XX, or the protrusion 21301 can extend from the bottom of the first sub-locking groove 21311 in a direction perpendicular to the first pivot axis XX. See also... Figure 7 The first engaging end 20111 is provided with a groove 20101 that mates with the protrusion 21301. See also Figure 9 When the first engaging end 20111 is inserted into either of the first sub-locking slots 21311, the protrusion 21301 and the groove 20101 engage in a convex-concave fit. This increases the contact area between the first engaging end 20111 and the first sub-locking slot 21311, allowing for more reliable locking of the relative positions of the first pivot seat 213 and the second pivot seat 223.

[0117] See Figure 9 and Figure 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 that the small pivot angle between the two positioning positions of the second pivot seat 223 and the first pivot seat 213 makes it inconvenient to arrange the first sub-locking grooves 21311. When the first engaging end 20111 engages with either of the two adjacent first sub-locking grooves 21311, the first engaging end 20111 engages with the overlapping portion 213110. Of course, in some alternative embodiments, two adjacent first sub-locking grooves 21311 can be separated from each other and do not have overlapping portions.

[0118] See also Figure 6 and Figure 7 The second end of the first locking member 2011 is configured as a second engaging end 20112. The second engaging end 20112 and the first engaging end 20111 are located at opposite ends of the first locking member 2011. The first pivot axis XX is located between the first engaging end 20111 and the second engaging end 20112. At least two first locking slots 2131 include at least two second sub-locking slots 21312, which are arranged sequentially in the circumferential direction. The second engaging end 20112 selectively engages with one of the at least two second sub-locking slots 21312.

[0119] See also Figure 6 and Figure 7The second engaging end 20112 may be provided with a second protrusion 20113 extending in a direction parallel to the first pivot axis XX. The second engaging end 20112 engages with one of the second sub-locking grooves 21312 via the second protrusion 20113. The first pivot seat 213 may include a second limiting groove 21313. Each of the second sub-locking grooves 21312 may communicate with the second limiting groove 21313. When the second protrusion 20113 of the second engaging end 20112 exits from the second sub-locking groove 21312, it enters the second limiting groove 21313. The wall 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 serve 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 213 and the second pivot 223.

[0120] See Figure 6 The second limiting groove 21313 is, for example, fan-shaped, and each second sub-locking groove 21312 communicates with the second limiting groove 21313 on the radial inner side of the second limiting groove 21313.

[0121] In this embodiment, the vehicle 200, when the first locking mechanism 201 is in the locked state, has its first engaging end 20111 of the first locking member 2011 selectively engaging with one of at least two first sub-locking slots 21311, and its second engaging end 20112 selectively engaging with one of at least two second sub-locking slots 21312. This allows for more reliable locking of 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 disengages from the first sub-locking slot 21311, and the second engaging end 20112 disengages from the second sub-locking slot 21312. It is understood that in other embodiments, the implementation of the first engaging end 20111 and the first sub-locking slot 21311, and the implementation of the second engaging end 20112 and the second sub-locking slot 21312 are not limited to the examples described above. The two ends of the first locking member 2011 selectively engage with the corresponding first locking groove through the engaging end, thereby achieving the purpose of locking the relative position of the first pivot seat 213 and the second pivot seat 223 more reliably.

[0122] See Figure 9 and Figure 10The first elastic reset member 2012 is located in the receiving cavity 2230. Both ends of the first elastic reset member 2012 abut against the first locking member 2011 and the second pivot seat 223, respectively. The first elastic reset member 2012 directly drives the first locking member 2011 to move towards the first locked position. Of course, in some alternative embodiments, the first elastic reset member 2012 can indirectly drive the first locking member 2011 to move towards the first locked position.

[0123] Figure 14 It shows Figure 5 MM section view. See also Figure 7 and Figure 14 The first release member 2013 is mounted on the top of the support frame 22, more specifically, on the upper U-shaped rod 2221 and away from the second pivot seat 223. The first locking mechanism 201 may also include a first cable 2014. The first release member 2013 is operatively connected to the first locking member 2011 via the first cable 2014. More specifically, see... Figure 14 The first end of the first cable 2014 is operably connected to the first release element 2013. See also Figure 9 and Figure 10 The second end of the first cable 2014 is connected to the first locking member 2011. In some embodiments, the first unlocking member 2013 is a knob, and the first unlocking member 2013 is operably connected to the first end of the first cable 2014 via a central structure 2015, such as... Figure 14 As shown in the diagram, when the first release member 2013 rotates relative to the upper U-shaped rod 2221 under the release force, the inclined surface 20151 of the central structure 2015 converts the rotation of the first release member 2013 into the movement of the first pull cable 2014, which in turn pulls the first locking member 2011 to the first release position. When the first release member 2013 is no longer under the release force, the first elastic reset member 2012 drives the first locking member 2011 to move to the first locking position, while the first pull cable 2014 can drive the first release member 2013 to reset through the central structure 2015. The way 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 can be a button that moves up and down or a push button that moves laterally.

[0124] See you again Figure 3 and Figure 4The second locking mechanism 202 has a locked state and an unlocked state. When the latching seat 219 is engaged with the mounting base 19 and the second locking mechanism 202 is in the locked state, the second locking mechanism 202 locks the latching seat 219 onto the mounting base 19, preventing the latching seat 219 from accidentally detaching from the mounting base 19. When the latching seat 219 is engaged with the mounting base 19 and the second locking mechanism 202 is in the unlocked state, the second locking mechanism 202 no longer locks the latching seat 219 onto the mounting base 19, and the latching seat 219 can be removed from the mounting base 19.

[0125] See Figure 2 and Figure 3 The mounting base 19, for example, has a first engaging recess 190, and the mounting base 219 engages with the first engaging recess 190. In some alternative embodiments, the first engaging recess may be provided on the mounting base 219, and the mounting base 19 engages with the first engaging recess.

[0126] See Figure 4 , Figure 6 and Figure 7 The wall of the latching seat 219 is provided with a first through hole 2190 communicating with the receiving groove 2120. The second locking mechanism 202 includes a second locking member 2021, a second elastic reset member 2022, and a second release member 2023. The second locking member 2021 is slidably engaged with the first through hole 2190 to be movable to a second locked position or a second released position. The moving direction of the second locking member 2021 is parallel to the first pivot axis XX. The second elastic reset member 2022 is used to drive the second locking member 2021 to move to the second locked position. The second release member 2023 is used to drive the second locking member 2021 to move to the second released position.

[0127] See Figure 3 The wall of the first engaging recess 190 is provided with an outwardly protruding limiting member 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 is in the second locked position, extending below the limiting member 191 and abutting against it, thereby preventing the engaging seat 219 from being pulled out of 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 unlocked state, the second locking member 2021 is in the second unlocked position, retracting into the receiving groove 2120 and disengaging from the limiting member 191, allowing the engaging seat 219 to be pulled out of the first engaging recess 190.

[0128] In some alternative embodiments, the limiting member 191 can be replaced by 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 is inserted into the second locking groove. When the second locking mechanism 202 is in the unlocked state, the second locking member 2021 is disengaged from the second locking groove. In some embodiments, the limiting member 191 and the second locking groove can be provided simultaneously on the wall of the first engaging recess 190. When the second locking mechanism 202 is in the locked state, the second locking member 2021 is inserted into the second locking groove and simultaneously abuts against the limiting member 191 below.

[0129] See Figure 6 and Figure 7 The second unlocking member 2023 includes a connecting portion 20231 and an operating portion 20232. The connecting portion 20231 is located in the receiving groove 2120 and is operably connected to the second locking member 2021. The groove wall of the receiving groove 2120 is provided with a second opening 21201, and the operating portion 20232 is slidably engaged with the second opening 21201. The moving direction of the operating portion 20232 is perpendicular to the moving direction of the second locking member 2021. When the operating portion 20232 is pushed by an external unlocking force, it drives the second unlocking member 2023 to move to a second unlocking position through the connecting portion 20231.

[0130] See Figure 6 The connecting portion 20231 of the second unlocking member 2023 is provided with a groove 202301. A third protrusion 20202 is provided on the wall of the receiving groove 2120, extending into the groove 202301. A second elastic reset member 2022 is located in the groove 202301. One end of the second elastic reset member 2022 abuts against the wall of the groove 202301, and the other end abuts against the third protrusion 20202. The connecting portion 20231 is provided with a driving inclined groove 202302, and the second locking member 2021 is provided with a driving pin 2024, which slides in conjunction with the driving inclined groove 202302. In some alternative embodiments, the positions of the driving inclined groove 202302 and the driving pin 2024 on the connecting portion 20231 and the second locking member 2021 can be interchanged.

[0131] When the second release member 2023 moves under the push of an external release force, the second elastic reset member 2022 is compressed and deformed. One side of the inclined wall of the drive groove 202302 pushes against the drive pin 2024. The drive pin 2024, while moving along the drive groove 202302, drives the second locking member 2021 to move towards the second release position. When the second release member 2023 is no longer pushed by the external release force, the second elastic reset member 2022 resets while simultaneously pushing the second release member 2023 to reset. During the reset process of the second release member 2023, the other side of the inclined wall of the drive groove 202302 pushes against the drive pin 2024. The drive pin 2024, while moving along the drive groove 202302, drives the second locking member 2021 to move towards the second locking position. In some examples of this utility model, the direction of the external release force on the second release member 2023 is consistent with the direction of lifting the vehicle 200 from the frame 100. In some alternative embodiments, the direction of the external release force on the second release member 2023 may be opposite to the direction of lifting the vehicle 200 from the frame 100.

[0132] See Figure 2 The second locking element 2021 is provided with an inclined surface 20211. See also... Figure 3 The limiting member 191 is provided with an inclined surface 1911. When the latching seat 219 is inserted into the first engaging recess 190 and the inclined surface 20211 abuts against the inclined surface 1911, the second locking member 2021 is forced to move towards the second unlocking position, and the latching seat 219 can continue to move downward. After the second locking member 2021 passes the limiting member 191, the second locking member 2021 automatically extends below the limiting member 191 to abut against the limiting member 191. In some alternative embodiments, the inclined surface 1911 of the limiting member 191 and the inclined surface 20211 of the second locking member 2021 can be selectively provided.

[0133] Figure 15 and Figure 16 Partial exploded views of the handrail assembly 300 in different directions are shown. Figure 17 It shows Figure 5 NN cross-sectional view, Figure 18 It shows Figure 4 YY sectional view. Figure 19 A perspective view shows an armrest assembly 300 with one end separated from the vehicle 200 and the other end connected to the vehicle 200. Figure 20 and Figure 21 It shows Figure 19 The SS sectional view shows the armrest assembly 300 in different opening processes. Figure 22 Another perspective view shows one end of the handrail assembly 300 separated from the passenger vehicle 200 and the other end connected to the carrier 200.

[0134] See Figure 15 and Figure 16 The handrail assembly 300 includes a first connecting seat 31, a second connecting seat 32, a third connecting seat 33, a handrail tube 34, a third locking mechanism 35, and a fourth locking mechanism 37. The structure of the handrail assembly 300 is generally symmetrical from left to right.

[0135] The handrail tube 34 is generally U-shaped. Each of the two ends of the handrail tube 34 is provided with a third connecting seat 33. Each third connecting seat 33 is fixed to the handrail tube 34 and cannot move or rotate relative to the handrail tube 34. Each third connecting seat 33 is pivotally connected to a second connecting seat 32 via a third pivot 393, the center line of which forms a third pivot axis PP. Each second connecting seat 32 is pivotally connected to a first connecting seat 31 via a second pivot 392, the center line of which forms 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) are located near the opposite ends of the second connecting seats 32, with the third pivot axis PP perpendicular to the second pivot axis CC.

[0136] The first connecting seat 31 is used for detachable connection with the support frame 22 of the vehicle 200. When the first connecting seat 31 is installed on the vehicle 200, the fourth locking mechanism 37 can lock the armrest assembly 300 to the support frame 22 of the vehicle 200.

[0137] See Figure 15 A second engaging recess 315 is provided on one side of the first connecting seat 31, and a cavity 316 is provided on the other side of the first connecting seat 31. A fourth locking mechanism 37 is mounted on the first connecting seat 31. The fourth locking mechanism 37 includes a fourth locking member 371 and a fourth elastic reset member 372. The fourth locking member 371 is installed in the cavity 316 and pivotally connected to the first connecting seat 31 via a pin 373. A fourth protrusion 3711 is provided at the first end of the fourth locking member 371, and the fourth elastic reset member 372 is held between the second end of the fourth locking member 371 and the wall of the cavity 316. Figure 15 The fourth elastic reset member 372 is blocked by the fourth locking member 371, so the fourth elastic reset member 372 is shown in dashed line. The wall of the cavity 316 is provided with a second through hole 3710 corresponding to the position of the fourth protrusion 3711. The fourth protrusion 3711 can enter the second engaging recess 315 through the second through hole 3710.

[0138] See Figure 19The support frame 22 has a locking protrusion 225, on which a fourth locking groove 2250 is provided. When the second locking recess 315 and the locking protrusion 225 are engaged and the fourth locking mechanism 37 is in the locked state, the fourth protrusion 3711 is inserted into the fourth locking groove 2250 under the pushing force of the fourth elastic reset member 372, and the first connecting seat 31 is locked onto the support frame 22. When the second locking recess 315 and the locking protrusion 225 are engaged and the fourth locking mechanism 37 is in the unlocked state, the second end of the fourth locking member 371 is pressed, and the fourth protrusion 3711 is disengaged from the fourth locking groove 2250, so that the first connecting seat 31 can be removed from the support frame 22.

[0139] See also Figure 15 and Figure 16 The second connecting seat 32 is pivotally connected to the first connecting seat 31 via a second pivot 392, which allows the handrail tube 34 to rotate, for example, swing up and down, so that the handrail assembly 300 can be switched to different working states. The handrail assembly 300, for example, has Figure 5 The handrail status shown and Figure 12 The handle is shown in its current state. As mentioned earlier, when the vehicle 200 is in... Figure 5 When the seat is in the indicated position, the armrest assembly 300 can be switched to the armrest position, at which time the armrest tube 34 extends forward above the seat plate 21. When the vehicle 200 is in... Figure 12 When in the sleeping box state shown, the armrest assembly 300 can be switched to the handle state, at which time the armrest tube 34 extends approximately in a direction perpendicular to the surface of the seat plate 21.

[0140] The third locking mechanism 35 is used to lock the relative positions of the second connecting seat 32 and the first connecting seat 31, thereby fixing the handrail assembly 300 in a certain working state. The third locking mechanism 35 has a locked state and an unlocked state. When the third locking mechanism 35 is in the locked state, the relative positions of the second connecting seat 32 and the first connecting seat 31 are locked and cannot be rotated relative to each other, and the handrail assembly 300 is maintained in a certain working state. When the third locking mechanism 35 is in the unlocked state, the second connecting seat 32 and the first connecting seat 31 can rotate relative to each other about the second pivot 392, and the working state of the handrail assembly 300 can be adjusted at this time.

[0141] See also Figure 15 and Figure 16At least two third locking grooves 313 are provided on the peripheral wall of the first connecting seat 31, and the at least two third locking grooves 313 are arranged sequentially in the circumferential direction. The second connecting seat 32 is provided with a sliding groove 323. The extending direction of the sliding groove 323 is perpendicular to the second pivot axis CC. A third locking mechanism 35 is provided on the second connecting seat 32. The third locking mechanism 35 includes a third locking member 351, a third elastic reset member 352, and a third unlocking member 353. The third locking member 351 slides in cooperation with the sliding groove 323 to move to a third locking position or a third unlocking position along a direction perpendicular to the second pivot axis CC. The third elastic reset member 352 is used to drive the third locking member 351 to move to the third locking position. The third unlocking member 353 is used to drive the third locking member 351 to move to the third unlocking position.

[0142] See Figure 17 and Figure 18 When the third locking mechanism 35 is in the locked state, the third locking member 351 is in the third locked position, and the third locking member 351 cooperates with one of the at least two third locking slots 313. The first connecting seat 31 and the second connecting seat 32 cannot rotate relative to each other, and the handrail assembly 300 is positioned in a certain working state. When the third locking mechanism 35 is in the unlocked state, the third locking member 351 is in the third unlocked position, and the third locking member 351 retracts from the third locking slot 313. The first connecting seat 31 and the second connecting seat 32 can rotate relative to each other, and the user can switch the working state of the handrail assembly 300 as needed.

[0143] It should be noted that although the handrail assembly 300 is described in this embodiment with two working states: handrail state and handle state, it can be understood that in actual applications, the handrail assembly 300 can have other working states by designing the number and position of the third locking slots 313.

[0144] See Figures 15 to 17 A first opening 3231 is provided on the wall of the sliding groove 323, and the third releasing member 353 is connected to the third locking member 351 through the first opening 3231. A third elastic reset member 352 is disposed in the sliding groove 323, with its two ends abutting against the bottom of the sliding groove 323 and the third locking member 351, respectively. When the third releasing member 353 is subjected to a releasing force, it moves along the first opening 3231 while simultaneously driving the third locking member 351 to move to the third releasing position. When the third locking member 351 moves to the third releasing position, the third elastic reset member 352 is compressed. When the releasing force on the third releasing member 353 is removed, the third elastic reset member 352 automatically resets, simultaneously driving the third locking member 351 to move to the third locking position.

[0145] The second connecting seat 32 may also be provided with a cover 326, which can cover the third locking groove 313 that does not cooperate with the third locking member 351, so as to prevent the third locking groove 313 from being exposed.

[0146] See Figure 15 The third connecting seat 33 is provided with a pivot groove 331. One end of the second connecting seat 32 has a pivot joint 322 that inserts into the pivot groove 331. The pivot joint 322 is pivotally connected to the third connecting seat 33 via a third pivot 393. The pivot joint 322 is provided with a second elongated hole 3232. A sliding pin 355 is provided on the third locking member 351. The sliding pin 355 is parallel to the third pivot axis PP and slides in engagement with the second elongated hole 3232. The wall of the pivot groove 331 is provided with a drive groove 333, and the end of the sliding pin 355 extends into the drive groove 333.

[0147] See Figures 19 to 22 When the first connecting seat 31 at one end of the handrail assembly 300 disengages from the support frame 22, the third connecting seat 33 at the other end of the handrail assembly 300 can rotate in the opening direction around the third pivot axis PP. During the rotation of the third connecting seat 33, the side wall 3331 of the drive groove 333 ( Figure 17 , Figure 20 and Figure 21 (The shape of the drive groove 333 is shown in dashed lines) pushes the sliding pin 355 to move along the second elongated hole 3232, causing the third locking member 351 to move to the third unlocking position, and the third locking member 351 to disengage from the third locking groove 313. Then, the handrail tube 34, the third connecting seat 33, and the second connecting seat 32 can move together about the second pivot axis CC to Figure 22 The vehicle is in the stowed state shown, which makes it easy for children to leave the vehicle 200.

[0148] In some embodiments, when the first connecting seat 31 at one end of the handrail assembly 300 disengages from the support frame 22, the third connecting seat 33 at the other end of the handrail assembly 300 rotates approximately 90 degrees in the opening direction (i.e., opens outwards by 90 degrees) about the third pivot axis PP, and the handrail assembly 300 reaches the fully open state. At this time, the third locking member 351 moves to the third unlocking position. Then, the handrail tube 34, the third connecting seat 33, and the second connecting seat 32 can rotate about the second pivot axis CC and move closer to the support frame 22, and the handrail assembly 300 moves to... Figure 22 The armrest assembly 300 is shown in the stowed state. In some embodiments, when the armrest assembly 300 is in the stowed state, the armrest assembly 300 abuts against the support frame 22.

[0149] In some embodiments not shown, the stroller provided in the first embodiment of this utility model may have the following variations, for example.

[0150] 1. The first locking member 2011 of the first locking mechanism 201 can slide and engage with the first pivot seat 213, and move between a first locking position and a second locking 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 in the second pivot seat 223.

[0151] Second, one end of the first locking member 2011 serves as an engaging end, while the other end is not used to engage with the first locking groove. That is, the first locking member 2011 may have only one of the first engaging end and the second engaging end. Correspondingly, only one of the first sub-locking groove 21311 and the second sub-locking groove 21312 may be provided.

[0152] 3. 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 variant example not shown, the first engaging end 20111 is provided with a first protrusion. The structure of the first protrusion is similar to that of the protrusion 21301, only with a change in its position. Therefore, the first protrusion can also be called the first protrusion 21301. The first protrusion 21301 protrudes along a direction parallel to the first pivot axis XX. The first protrusion 21301 is used to mate with the corresponding first sub-locking groove. In other words, in this case, the first protrusion 21301 of this variant example is formed by exchanging 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 are connected to the first limiting groove of the first pivot seat 213. After the first protrusion 21301 exits from the corresponding first sub-locking slot, it moves into the first limiting slot.

[0153] Additionally, in some embodiments not shown, the structure of the second engaging end 20112 and the second sub-locking groove 21312 can be similar to the structure of the first engaging end 20111 and the first sub-locking groove 21311. That is, the wall of the second sub-locking groove is provided with a protrusion that extends in a direction parallel to the first pivot axis XX. The second engaging end may be provided with a groove that mates with the protrusion. Furthermore, two adjacent second sub-locking grooves may have overlapping portions.

[0154] IV. The implementation of the first release member 2013 and the first elastic reset member 2012 is not limited to the examples above, as long as it can control the first locking member 2011 to extend into or exit from the first locking groove 2131. For example, in some alternative embodiments, the first locking member 2011 is directly connected to the first release member 2013, and the first release member 2013 extends from the receiving cavity 2230 for pressing. The first release member 2013 and the first locking member 2011 can be, but are not limited to, integrally formed, which can omit the first cable 2014, the centering structure 2015, etc.

[0155] 5. The second locking mechanism 202 can be disposed on the mounting base 19, and the second locking groove and / or limiting member 191 can be disposed on the snap-fit ​​base 219. In this case, the snap-fit ​​base 219, the connecting arm 212, and the first pivot base 213 can be integrally formed parts, for example. The implementation of the second release member and the second elastic reset member is not limited to the examples above, as long as the movement of the second locking member between the second locking position and the second release position can be controlled.

[0156] 6. The third connecting seat 33 can be omitted, and the second connecting seat 32 is directly fixedly connected to the handrail tube 34. Under the action of the third locking mechanism 35, the handrail assembly 300 can still switch to different working states.

[0157] 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 positions of the second connecting seat 32 and the first connecting seat 31.

[0158] 8. The positions of the second engaging recess 315 and engaging protrusion 225 on the first connecting seat 31 and the support frame 22 can be interchanged. The positions of the fourth locking mechanism 37 and the fourth locking groove 2250 on the first connecting seat 31 and the support frame 22 can also be interchanged. Furthermore, the implementation of the fourth locking mechanism 37 is not limited to the above examples, as long as it can lock the first connecting seat 31 and the support frame 22 together.

[0159] The following will refer to Figures 23 to 33 Description of a child stroller 1000 according to a second embodiment of the present invention.

[0160] Figure 23 and Figure 24 A perspective view and a side view of a child stroller 1000 provided according to a second embodiment of the present invention in a usage state are shown. The child stroller includes a frame 100, a seating carrier 200, an armrest assembly 300, a canopy support assembly 400, etc. Figure 23 and Figure 24The riding vehicle 200 is in sleeping box mode, providing a lying space for children. Figures 25 to 27 It shows Figure 23 and Figure 24 The structure of the 200 passenger vehicles from different perspectives. Figure 28 A side view of the stroller 1000 in another usage state is shown, with the seating 200 in a seated position and the backrest area 2313 of the seating 200 at an angle. Figure 29 It shows Figure 28 A partial rear view of the stroller 1000 shown. Figures 30 to 32 It shows Figure 28 The structure of the 200 passenger vehicles from different perspectives. Figure 33 In the stroller 1000 shown, the seating 200 is in a seated position, and the backrest area 2313 of the seating 200 is at another tilt angle.

[0161] See Figures 23 to 25 The passenger vehicle 200 is detachably mounted to the frame 100. Of course, in some alternative embodiments, the passenger vehicle 200 may be non-detachably connected to the frame 100. An armrest assembly 300 is mounted to the passenger vehicle 200. A canopy support assembly 400 is mounted to the passenger vehicle 200. The canopy support assembly 400 includes a canopy 41, which can be deployed or retracted. The canopy support assembly 400 is not essential in some alternative embodiments.

[0162] Similar to the first embodiment, the frame 100 according to the second embodiment also includes a front support frame 11, a rear support frame 12, an upper support frame 13, a handlebar frame 14, a shock absorber frame 15, a storage rack 16, a wheel assembly 17, a mounting base 19, etc. The frame 100 can be a foldable frame or a non-foldable frame. The structure of the frame 100 is generally symmetrical from left to right.

[0163] The front support frame 11 includes two front struts 111 and a front crossbar 112 connecting the two front struts 111. The front support frame 11 is generally U-shaped. Due to the angular relationship shown by the frame 100, the front crossbar 112 is not in... Figure 23 and Figure 24 The details are shown above. For a detailed description of the front support frame 11, please refer to the above description. Figures 1 to 3 The relevant description of the front support frame 11 shown.

[0164] The front wheel of wheel assembly 17 is mounted on front support frame 11. Handrail 14 includes two handrail members 141 and a handrail crossbar 142 connecting the two handrail members 141. Handrail 14 is generally U-shaped. Upper support frame 13 includes two upper members 131, the lower ends of which are connected to the upper ends of two front members 111, and the upper ends of which are connected to the lower ends of two handrail members 141. Rear support frame 12 includes two rear members 121 and a rear crossbar 122 connecting the two rear members 121. Rear support frame 12 is generally H-shaped. The rear wheel of wheel assembly 17 is mounted on rear support frame 12. The upper ends of the two rear members 121 are connected to the two front members 111. The shock absorber frame 15 includes two shock absorber rods 151. The upper end of each shock absorber rod 151 is connected to the adjacent upper rod 131, and the lower end of each shock absorber rod 151 is connected to the adjacent rear rod 121 on the same side.

[0165] The storage rack 16 includes two storage rods 161 and a storage crossbar 162 connecting the two storage rods 161. The storage rack 16 is generally U-shaped. The middle part of the storage rack 16 is connected to the shock absorber 151 on the same side via connecting rods 18. Since the frame 100 according to the second embodiment also includes a storage basket 165 disposed on the storage rack 16, the storage rods 161 and the storage crossbar 162 are obstructed by the storage basket 165. Figure 23 and Figure 24 Not shown in the figure, the detailed structure of the shelf 16 can be found above. Figures 1 to 3 The description of the storage rack 16 is shown below. In some embodiments, the frame 100 (specifically, the rear support frame 12) may be provided with a symmetrical braking mechanism 123 as described in the first embodiment. Due to the obstruction of the storage basket 165, the braking mechanism 123... Figure 23 and Figure 24 Not shown. In some embodiments, the braking mechanism 123 may be biased to one side of the frame 100.

[0166] Mounting seats 19 are provided on both the left and right sides of the frame 100. Each mounting seat 19 can be connected to the shock absorber bar 151 or to the upper rod 131. Of course, the implementation of the frame 100 is not limited to this.

[0167] See Figures 25 to 27 Each of the left and right sides of the vehicle 200 has a locking seat 219, which is used to detachably engage with the mounting seat 19 of the frame 100. To avoid redundancy, the detailed structure of the mounting seat 19 and the locking seat 219, and the connection method between them, will not be described in detail here. Please refer to the above description for more information. Figures 1 to 7 Description of the mounting base 19 and the snap-fit ​​base 219 shown.

[0168] The passenger vehicle 200 can be mounted forward or backward on the frame 100. In the second embodiment, the passenger vehicle 200 is mainly described as being mounted backward on the frame 100.

[0169] The following is combined with Figure 23 , Figure 24 and Figure 28 This describes the case where the vehicle 200 is mounted rearward on the frame 100. See [link / reference]. Figure 23 and Figure 24 When the riding vehicle 200 is in sleeping box mode, one end of the riding vehicle 200 used to position the canopy support assembly 400 is away from the caregiver pushing the stroller 1000 (i.e., away from the handrail 14). See also Figure 28 When the vehicle 200 is in the seat position, the child sitting in the vehicle 200 faces the rear of the direction of travel and is facing the caregiver pushing the stroller 1000.

[0170] Conversely, when the riding vehicle 200 is mounted forward on the frame 100, if the riding vehicle 200 is in sleeping position, the end of the riding vehicle 200 used to set the canopy support assembly 400 is closer to the caregiver pushing the stroller 1000 (i.e., closer to the handrail 14). If the riding vehicle 200 is in seat position, the child sitting in the riding vehicle 200 faces forward along the direction of travel and has their back to the caregiver pushing the stroller 1000.

[0171] Similar to the first embodiment, in the second embodiment of this invention, the "front," "rear," "left," and "right" positions of the child riding in the vehicle 200 are used as a reference. Figure 23 Arrows F1 and B1 schematically indicate the "front" and "rear" directions of the frame 100, and arrows L1 and R1 schematically indicate the "left" and "right" directions of the frame 100. Depending on the mounting direction of the passenger vehicle 200 on the frame 100, the front-rear, left-right, and right-right orientations of the passenger vehicle 200 can be the same as or opposite to the front-rear, left-right, and right-right orientations of the frame 100. For details, see [link to documentation]. Figure 23 , Figure 24 and Figure 28 When the vehicle 200 is mounted rearward on the frame 100, the front-rear and left-right orientations of the vehicle 200 and the frame 100 are opposite, and Figures 25 to 27Arrows F2 and B2 schematically indicate the "front" and "rear" directions of the vehicle 200, and arrows L2 and R2 schematically indicate the "left" and "right" directions of the vehicle 200. It can be understood that when the vehicle 200 is mounted forward on the frame 100, the front-rear, left-right, and right-right orientations of the vehicle 200 are the same as those of the frame 100. Please refer to arrows F2, B2, L2, and R2 for the "front," "rear," "left," and "right" orientations of the vehicle 200 in the following text.

[0172] The seat plate 21 may include a support plate 211. The support plate 211 may be a sheet material made of plastic. See also... Figure 28 When the vehicle 200 is in seat position, the support plate 211 supports the child's buttocks. Connecting arms 212 are respectively provided on the left and right sides of the support plate 211, extending upwards from the support plate 211. In some embodiments, the connecting arms 212 and the support plate 211 can be separate components, fixedly connected together. In some embodiments, the connecting arms 212 and the support plate 211 can be integrally formed. Each connecting arm 212 has a first pivot seat 213 as described in the first embodiment at its upper end. To avoid redundancy, the specific structure of the first pivot seat 213 is not described in the first embodiment. Figures 22 to 33 As shown in the figure, and for detailed information about the structure of the first pivot 213, please refer to the relevant description of the first pivot 213 according to the first embodiment.

[0173] The connecting arm 212 can be a one-piece structure or a combination of multiple parts. Figure 25 The connecting arm 212 is composed of multiple components, including an L-shaped component 2121, a centering component 2122, and a base 2123. Two perpendicular plates of the L-shaped component 2121 are fixedly connected to the support plate 211 and the centering component 2122, respectively. The centering component 2122 is connected to the base 2123. A snap-fit ​​seat 219 is disposed on the base 2123, and the snap-fit ​​seat 219 and the base 2123 may be, but are not limited to, integrally formed. A first pivot seat 213 is disposed at the upper end of the base 2123, and the first pivot seat 213 and the base 2123 may be, but are not limited to, integrally formed. In the second embodiment, the connecting arm 212 can be composed of multiple components, and multiple models of the centering component 2122 can be provided, allowing the model of the centering component 2122 to be replaced as needed, thus 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 examples described above.

[0174] See Figure 26The support frame 22 is, for example, annular, and can also be referred to as a surrounding frame. The seat fabric 23 includes a bottom fabric 231 and a barrier 232. The barrier 232 is connected between the perimeter of the bottom fabric 231 and the support frame 22. More specifically, the upper edge of the barrier 232 fits over the support frame 22. The bottom fabric 231 is connected to the lower edge of the barrier 232, closing the bottom opening of the barrier 232.

[0175] The support frame 22 includes two support rods 221 arranged opposite each other on the left and right sides. Each support rod 221 is provided with a second pivot seat 223 as described in the first embodiment. The second pivot seat 223 is 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 about a first pivot axis XX, which can extend in the left and right direction. When the riding vehicle 200 is installed on the frame 100, the positions of the seat plate 21 and the first pivot seat 213 are fixed. When the support frame 22 is subjected to an external pivoting force, the support frame 22 and the second pivot seat 223 rotate about the first pivot axis XX relative to the first pivot seat 213, that is, the support frame 22 rotates about the first pivot axis XX relative to the seat plate 21, so that the riding vehicle 200 can be switched to a sleeping box state or a seat state.

[0176] In some embodiments, considering the situation where a child is seated in the vehicle 200, the center of gravity of the support plate 211 is, for example, 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 located 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.

[0177] See Figures 24 to 26 When the riding vehicle 200 is in its sleeping position, the support frame 22 is arranged generally horizontally, the enclosure 232 extends downwards and is fully extended, and the bottom fabric 231 is suspended below the support frame 22 by the enclosure 232. A support plate 211 supports the bottom fabric 231 from below. The bottom fabric 231 provides a relatively flat support surface for the child to lie down. Additionally, when the riding vehicle 200 is in its sleeping position and removed from the frame 100, it can be used independently. The armrest assembly 300 can be switched to a carrying handle position for easy movement of the riding vehicle 200 by the user.

[0178] See Figure 28 and Figure 30When the vehicle 200 is in the seat position, the seat 21 remains stationary, while the support frame 22 rotates relative to the seat 21, tilting to an angle. The shapes of the bollard 232 and the floor 231 change to define a space for the child to sit in a seated position. Furthermore, the armrest assembly 300 can pivot relative to the support frame 22 to an armrest position, extending forward above the seat 21.

[0179] As in the first embodiment, the circumferential relative positions of the first pivot 213 and the second pivot 223 in the second embodiment can be locked by the first locking mechanism 201. The first locking mechanism 201 has a locked state and an unlocked state. When the first locking mechanism 201 is in the locked state, the relative positions of the first pivot 213 and the second pivot 223 are locked and cannot be rotated relative to each other, and the vehicle 200 is fixed in either a seat state or a sleeping box state. When the first locking mechanism 201 is in the unlocked state, the first pivot 213 and the second pivot 223 can rotate relative to each other, and the vehicle 200 can switch between a sleeping box state and a seat state. To avoid redundant description, the specific structure of the first locking mechanism 201 will not be described again here, and can be understood by referring to the above description of the first locking mechanism 201 in the first embodiment.

[0180] See Figure 26 and Figure 27 ,as well as Figure 31 and Figure 32 Depending on the function of the vehicle 200 in the seated state, the bottom fabric 231 of the seat cover 23 includes a leg rest area 2311, a seat area 2312, and a backrest area 2313 that are sequentially adjacent to each other. The seat area 2312 and the leg rest area 2311 can be separated by a first seam or a first fold line 231a. The seat area 2312 and the backrest area 2313 can be separated by a second seam or a second fold line 231b. When the vehicle 200 switches between the seated state and the sleeping box state, the leg rest area 2311 and the backrest area 2313 can pivot relative to the seat area 2312.

[0181] As previously described, when the vehicle 200 is in the sleeping box state, the bottom fabric 231 extends generally horizontally, and the leg rest area 2311, seat area 2312, and backrest area 2313 work together to form a support surface for the child to lie down. The support plate 211 supports the bottom fabric 231 from below to improve the flatness of the bottom fabric 231. When the vehicle 200 switches to the seat state, the backrest area 2313 pivots upward relative to the seat area 2312, and at the same time, there is a tendency to pull the seat area 2312 backward.

[0182] When the vehicle 200 is in the seat position, the seat area 2312 substantially covers the support plate 211 located below the seat area 2312, and the support plate 211 supports the seat area 2312. The backrest area 2313 is tilted upward relative to the seat area 2312 and away from the support plate 211. The leg rest area 2311 is tilted downward relative to the seat area 2312 and away from the support plate 211. The seat area 2312 is for contact with the child's buttocks, the backrest area 2313 is for supporting the child's back, and the leg rest area 2311 is for supporting the child's legs.

[0183] In some embodiments, the leg rest area 2311 may be provided with a first hard board (not shown), the size of which is substantially matched, for example, to the size of the leg rest area 2311. The backrest area 2313 may be provided with a second hard board (not shown), the size of which is substantially matched, for example, to the size of the backrest area 2313. The seat area 2312 may be made of a flexible material without a hard board. When the riding vehicle 200 is in a sleeping position, at least a portion of the seat area 2312 may be supported by a support plate 211, the first hard board, the support plate 211, and the second hard board working together to provide a relatively flat support surface for the child.

[0184] In some embodiments not shown, the leg rest area 2311 includes, for example, an upper fabric layer and a lower fabric layer, defining a first receiving cavity between the upper and lower fabric layers. A first rigid board, for example, is a rigid plastic board, which can be fitted 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 seat area 2312 may also include an upper fabric layer and a lower fabric layer, with a cushioning layer sandwiched between the upper and lower fabric layers. The layered structure of the backrest area 2313 may be similar to that of the leg rest area 2311, also including an upper fabric layer and a lower fabric layer, and defining a second receiving cavity between the upper and lower fabric layers. A second rigid board, for example, is a rigid plastic board, which can be fitted 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 fabric layer and / or lower fabric layer of the leg rest area 2311, seat area 2312, and backrest area 2313 may themselves have certain cushioning properties.

[0185] See Figure 26 and Figure 27When the vehicle 200 is in sleeping position, the front side of the seating area 2312 extends forward from the front edge of the support plate 211, and the rear edge of the seating area 2312 is located between the front edge 2111 and the rear edge 2112 of the support plate 2111. That is, the boundary between the seating area 2312 and the leg rest area 2311 (the first seam or first fold line 231a) is located in front 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) is located between the front edge 2111 and the rear edge 2112 of the support plate 2111. The boundary between the seating area 2312 and the backrest area 2313 is, for example, close to the center of gravity of the support plate 211.

[0186] See Figure 32 When the vehicle 200 switches from a sleeping box state to a seat state, the seating area 2312 is pulled backward relative to the support plate 211 by the backrest area 2313, so that the front edge of the seating area 2312 (corresponding to the first seam or first fold line 231a) approaches the front edge 2111 of the support plate 211, and the rear edge of the seating area 2312 (corresponding to the second seam or second fold line 231b) approaches the rear edge 2112 of the support plate 211. The seating area 2312 substantially covers the support plate 211.

[0187] After the vehicle 200 switches from seat mode to sleeping box mode, pull the seat area 2312 forward, causing the seat area 2312 to move forward relative to the support plate 211. Figure 27 In this state, the base fabric 231 and the enclosure 232 can be unfolded to the ideal state.

[0188] When the passenger vehicle 200 of this utility model switches between sleeping box state and seat state, the seat area 2312 can move back and forth relative to the support plate 211. This can effectively avoid the problem of excessive local tension on the seat cloth 23 (especially excessive tension between the seat area 2312 and the backrest area 2313) interfering with the movement of the support frame 22, and effectively avoid the passenger vehicle 200 from malfunctioning.

[0189] Furthermore, the seating area 2312 is made of a flexible material instead of a rigid panel, which eliminates the need for the leg rest area 2311 and backrest area 2313 to pivot relative to the seating area 2312 about a fixed pivot axis. During the switching of the riding vehicle 200 between different states, the seat fabric 23 can provide greater deformation, thus reducing the likelihood of excessive local tension. Of course, in some alternative embodiments, the seating area 2312 may also be equipped with a rigid panel.

[0190] See Figure 31 and Figure 32The vehicle 200 also includes a restraint system 26. The restraint system 26 includes a crotch strap 261 and two shoulder straps 262. One end of the crotch strap 261 is connected to the seating area 2312, and the other end of the crotch strap 261 is detachably connected to one end of each of the two shoulder straps 262. The other end of each of the two shoulder straps 262 is connected to a backrest area 2313. In some embodiments, the backrest area 2313 is provided with a plurality of adjustment holes 23130. The other ends of the two shoulder straps 262 selectively engage with one of the plurality of adjustment holes 23130 to adapt the restraint system 26 to the child's body size.

[0191] See Figure 27 , Figure 29 and Figure 32 The vehicle 200 also includes a traction mechanism 27, and the backrest area 2313 is connected to the seating area 2312 via the traction mechanism 27. When the vehicle 200 switches from a sleeping box state to a seat state, the traction mechanism 27 and the backrest area 2313 together pull the seating area 2312 backward.

[0192] In some embodiments, when the vehicle 200 switches from a sleeping box state to a seat state, the backrest area 2313 applies an upward traction force to the seat area 2312, and the traction mechanism 27 applies a downward traction force to the seat area 2312 to facilitate the seat area 2312 to move generally horizontally backward along the support plate 211.

[0193] In some embodiments, the support plate 211 has two through holes 2110, which are arranged symmetrically from left to right. The traction mechanism 27 includes, for example, two adjustment straps 271 arranged symmetrically from left to right. The first end 2711 of each adjustment strap 271 is connected to the back of the seat area 2312, and the two are fixedly connected, for example, by sewing. The second end 2712 of each adjustment strap 271 passes through the corresponding through hole 2110 from top to bottom and extends rearward to connect to the back of the backrest area 2313. The second end of the adjustment strap 271 is connected to the backrest area 2313, for example, by sewing. Alternatively, the back of the backrest area 2313 is connected to a connecting buckle 29 by a webbing 291, and the second end 2712 of each adjustment strap 271 is connected to the connecting buckle 29. The connecting buckle 29 can be a D-ring or other fastener. The second end 2712 of the adjustment strap 271 and the connecting buckle 29 are detachably connected, for example. In some embodiments, the length of the adjustment strap 271 is adjustable.

[0194] When the vehicle 200 switches from a sleeping box state to a seat state, the backrest area 2313 applies a backward force to the seat area 2312 from above the support plate 211, and the adjustment strap 271 is tensioned and applies a backward force to the seat area 2312 from below the support plate 211. This helps the seat area 2312 to move backward along the support plate 211 and prevents it from tilting upward relative to the support plate 211. When the vehicle 200 switches to the seat state, the tensioned adjustment strap 271 can also be used to maintain the relative position of the seat area 2312 and the support plate 211.

[0195] See Figure 27 and Figure 32 The through hole 2110 is close to the rear edge of the support plate 211. In this way, when the vehicle 200 is in the sleeping box state, the length of the adjustment strap 271 exposed relative to the support plate 211 is relatively short.

[0196] The first end 2711 of the adjustment strap 271 is located near the boundary between the seating area 2312 and the backrest area 2313. In this way, when the vehicle 200 is in the seated position, the adjustment strap 271 pulls the seating area 2312 downward near the rear edge of the seating area 2312, which can counteract the upward pull exerted by the backrest area 2313 on the rear edge of the seating area 2312 at close range.

[0197] Of course, the implementation of the traction mechanism 27 is not limited to the examples described above. For example, in some alternative embodiments, the number of through holes 2110 on the support plate 211 may be one, three, or more. When there is one through hole 2110, the through hole 2110 is centered in the left-right direction. When there are multiple through holes 2110, the multiple through holes 2110 are symmetrically arranged in the left-right direction. Accordingly, the traction mechanism 27 may include one, three, or more adjusting straps 271.

[0198] See Figure 30 , Figure 32 and Figure 33 The seat cover 23 may also be provided with a backrest adjustment mechanism 28. When the vehicle 200 is in the seat position, the backrest adjustment mechanism 28 is used to adjust the tilt angle of the backrest area 2313 relative to the seat area 2312.

[0199] The backrest adjustment mechanism 28 may include two connecting straps 281 and a lock 282. The lock 282 is located on the back of the backrest area 2313. The first ends 2811 of the two connecting straps 281 are respectively connected to two support rods 221, and the second ends 2812 of the two connecting straps 281 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 protrude from the lock 282. By adjusting the length between the first ends 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 ends 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, and the more suitable the backrest area 2313 is for a lying position. The shorter the length between the first end 2811 of each connecting strap 281 and the lock 282, the greater the tilt angle of the backrest area 2313 relative to the seat area 2312, and the closer the backrest area 2313 is to being upright.

[0200] Lock 282 can be a one-way lock. When the one-way lock is in the locked state, it allows the second end 2812 of each connecting strap 281 to be pulled to shorten the length between the first end 2811 of each connecting strap 281 and lock 282. When it is necessary to increase the length between the first end 2811 of each connecting strap 281 and lock 282, the one-way lock needs to be switched to the unlocked state.

[0201] The enclosure 232 and / or the backing area 2313 may be provided with guide structures to guide the extension direction of each connecting strip 281. See also Figure 29 The guiding structure includes, for example, a channel 2320 disposed in the enclosure 232 and a channel 2321 disposed in the back area 2313. The channel 2320 is formed, for example, inside the enclosure 232. The channel 2321 is defined, for example, by the back of the back area 2313 and a strip 23131 disposed on the back of the back area 2313.

[0202] The following will refer to Figure 34 To describe the passenger vehicle 200 according to the third embodiment of the present invention.

[0203] Figure 34 This diagram shows a bottom perspective view of a passenger vehicle 200 according to a third embodiment of the present invention. Unless otherwise specified, the structure of this passenger vehicle 200 can be referred to the description in the second embodiment. The following mainly describes the differences between this third embodiment and the second embodiment.

[0204] See Figure 34The seat fabric 23 includes a first cover 237 located below a base fabric 231, the first cover 237 and the base fabric 231 defining a first pocket structure 239 for receiving a support plate 211. The first pocket structure 239 has first side openings 23701 on its left and right sides for the connecting arm 212 to extend from. In some embodiments, the first pocket structure 239 receives at least one adjustment strap 271. In some embodiments, the first pocket structure 239 has a rear opening 23702 for at least one adjustment strap 271 to extend from its rear side.

[0205] In some embodiments, the front edge 2371 of the first cover 237 is fixed to the back of the bottom fabric 231 (the side facing away from the child) by means of sewing, for example, and the sewing position of the front edge 2371 and the bottom 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 cover 237 can be fixed to the back of the backrest area 2313 by sewing. In some embodiments, the front edge 2371 of the first cover 237 may not be fixed to the back of the bottom fabric 231 by sewing, as long as the first cover 237 can cover the support plate 211.

[0206] The first cover 237 can be a fabric sheet or other type of sheet. By using the first cover 237 to cover the support plate 211, the appearance consistency of the vehicle 200 can be improved.

[0207] The following will refer to Figure 35 and Figure 36 To describe the passenger vehicle 200 according to the fourth embodiment of the present invention.

[0208] Figure 35 and Figure 36 A bottom view and a side view of the passenger vehicle 200 provided in the fourth embodiment of the present invention are shown. Unless otherwise specified, the structure of the passenger vehicle 200 can be referred to the description in the second embodiment. The following mainly describes the differences between the fourth embodiment and the second embodiment.

[0209] In this fourth embodiment, the adjusting strap 271 and connecting buckle 29 of the second embodiment are omitted. Correspondingly, the through hole 2110 for the adjusting strap 271 to pass through can be omitted from the support plate 211. A second cover plate 273 is provided below the bottom fabric 231, and the second cover plate 273 is used as the traction mechanism 27.

[0210] Specifically, the front edge 2731 of the second cover 273 connects to the front edge of the seating area 2312, and the rear edge 2732 of the second cover 273 connects to the backrest area 2313. The second cover 273 and the bottom fabric 231 define a second pocket structure 2730 for accommodating the support plate 211. The second pocket structure 2730 has second side openings 27301 on its left and right sides for the connecting arm 212 to extend out.

[0211] When the vehicle 200 switches from a sleeping box state to a seat state, the backrest area 2313 exerts a rearward force on the seat area 2312 from above the support plate 211, and the second cover 273 is stretched and exerts a rearward force on the seat area 2312 from below the support plate 211. The second pocket structure 2730 guides the relative movement of the support plate 211 and the seat area 2312.

[0212] In some embodiments, the left and right sides of the second cover 273 are connected to the seat fabric 23 (e.g., the seating area 2312) by means of sewing or other methods. Thus, when the vehicle 200 switches from a sleeping box state to a seat state, the connection between the left and right sides of the second cover 273 and the seat fabric 23 effectively prevents the seating area 2312 from moving left and right relative to the support plate 211. This facilitates the application of a more uniform backward-moving force to the seating area 2312 in the fore-and-aft direction, resulting in smoother movement of the seating area 2312.

[0213] See Figure 36 When the vehicle 200 is in the seat position, the support plate 211 and the second pocket structure 2730 cooperate to restrict the rearward movement of the seating area 2312 relative to the support plate 211. More specifically, the support plate 211 abuts against the front end of the second pocket structure 2730.

[0214] The following will refer to Figure 37 The fifth embodiment of the present invention is described below, which is a passenger vehicle 200.

[0215] Figure 37 A bottom view of a passenger vehicle 200 according to a fifth embodiment of the present invention is shown. Unless otherwise specified, the structure of this passenger vehicle 200 can be referred to the description in the fourth embodiment. The following mainly describes the differences between this fifth embodiment and the fourth embodiment.

[0216] See Figure 37 The rear edge 2732 of the second cover 273 is connected to the back of the backrest area 2313 by at least one connecting strap 274. When the riding vehicle 200 is in the sleeping box state, the rear edge 2732 of the second cover 273 is close to, for example, the rear edge 2112 of the support plate 211. In some embodiments, the length of the connecting strap 274 can be adjusted.

[0217] The following will refer to Figure 38 To describe the passenger vehicle 200 according to the sixth embodiment of the present invention.

[0218] Figure 38 A side view of a passenger vehicle 200 according to a sixth embodiment of the present invention is shown. Unless otherwise specified, the structure of this passenger vehicle 200 can be referred to the description in the second embodiment. The following mainly describes the differences between this sixth embodiment and the second embodiment.

[0219] See Figure 38 In this sixth embodiment, the connecting arm 212 can be a one-piece structure. For example, the connecting arm 212 is a one-piece molded part formed by injection molding. The snap-fit ​​seat 219 is directly formed on the connecting arm 212 and is integrally molded with it. For example, the first pivot seat 213 can be disposed at the upper end of the connecting arm 212.

[0220] In some embodiments, the connecting arm 212 and the support plate 211 can also be an integral structure. The connecting arm 212 and the support plate 211 are integrally formed, for example, by injection molding, so that no other fastening structure is needed to connect the connecting arm 212 and the support plate 211 together.

[0221] In some embodiments, the structures of each connecting arm 212 are generally symmetrical front to back, forming a front-back symmetry plane S. The front-back symmetry plane S of the two connecting arms 212 generally passes through the center of gravity of the support plate 211. In one embodiment of the present invention, the front-back symmetry plane S generally passes through the first pivot axis XX. This helps to stabilize the center of gravity of the seat plate 21. In some embodiments, the front-back symmetry plane S of each connecting arm 212 is generally perpendicular to the surface of the support plate 211.

[0222] The following will refer to Figures 39 to 42 To describe the passenger vehicle 200 according to the seventh embodiment of the present invention.

[0223] Figure 39 and Figure 40 The following are side views of a vehicle 200 provided according to a seventh embodiment of the present invention, taken from different perspectives. The vehicle 200 is in a sleeping box state. Figure 40 The tarpaulin 41 and seat cloth 23 are omitted. Figure 41 and Figure 42 It shows Figure 39 and Figure 40 The image shows perspective views of the seat 21 from different angles. Unless otherwise specified, the structure of the passenger vehicle 200 can be referred to the description in the sixth embodiment. The following mainly describes the differences between this seventh embodiment and the sixth embodiment.

[0224] See Figures 39 to 41A non-flattening protrusion 218 is provided on the seat plate 21. The protrusion 218 is, for example, provided on the bottom surface of the seat plate 21. When the vehicle 200 is removed from the frame 100, the non-flattening protrusion 218 prevents the seat plate 21 from lying stably flat on the plane H, such as... Figure 39 As shown. Therefore, in some embodiments of this utility model, the protruding structure 218 can also be referred to as an anti-misuse structure.

[0225] like Figure 39 As shown, the protruding structure 218 can protrude downward relative to the bottom surface of the seat plate 21. More specifically, the protruding structure 218 protrudes downward from the bottom surface of the support plate 211, for example. When the vehicle 200 is placed on the plane H, the protruding structure 218 first contacts the plane H, but the protruding structure 218 itself cannot stably support the vehicle 200 on the plane H, causing the vehicle 200 to be in an unbalanced state and prone to swaying and tilting, so that the bottom surface of the seat plate 21 also contacts the plane H.

[0226] This embodiment, by providing a protruding structure 218, places the riding vehicle 200 in an unstable, tilted state when placed on the plane H. This serves as a reminder to users not to leave infants or young children alone in the riding vehicle 200 in its sleeping position on the plane H, thus helping to eliminate safety hazards. Additionally, it also serves as a reminder to users not to place the riding vehicle 200 alone on the plane H, to prevent the front end 2301 or rear end 2302 of the seat cover 23 from contacting the plane H.

[0227] See also Figures 39 to 41 An exemplary embodiment of the protruding structure 218 is shown. The protruding structure 218 extends from the central region of the bottom surface of the support plate 211 towards the edge region of the support plate 211. The protruding structure 218 is generally arched (or arc-shaped) with a high center and low ends.

[0228] More specifically, in this embodiment, the protruding structure 218 is generally located in the middle of the bottom surface of the support plate 211 and extends in the left-right direction. The protruding structure 218 is generally arched in shape, higher in the middle and lower on the left and right sides. That is, the distance between the middle part of the protruding structure 218 and the bottom surface of the support plate 211 is relatively large, while the distance between the left and right sides of the protruding structure 218 and the bottom surface of the support plate 211 is relatively small. When the vehicle 200 is placed on the plane H, even if the bottom surfaces of the protruding structure 218 and the seat plate 21 are in contact with the plane H at the same time, the vehicle 200 is still prone to swaying in the front-back direction and the left-right direction.

[0229] See Figure 41 and Figure 42The protruding structure 218 is integrally formed with, for example, the seat plate 21 (more specifically, the support plate 211). The protruding structure 218 also enhances the structural strength and load-bearing capacity of the seat plate 21. In some embodiments, the protruding structure 218 forms an upward-opening inner cavity 2180, in which reinforcing ribs 2182 are provided, thus enhancing the structural strength of the seat plate 21 without unduly increasing its weight. Of course, in some alternative embodiments, the protruding structure 218 and the seat plate 21 can be separate components, which can be assembled together using a suitable structure.

[0230] Alternatively, in some alternative embodiments, the protrusion 218 may extend along the front-back direction or diagonal direction of the support plate 211.

[0231] See you again Figure 39 and Figure 41 In some embodiments, the bottom surface of the support plate 211 is provided with a guide surface 2115, which is located behind the through hole 2110, for example, adjacent to the rear edge of the through hole 2110. This guide surface 2115 slides with the adjustment band 271 to guide the adjustment band 271 away from the support plate 211. The guide surface 2115 is convex, more specifically, arc-shaped. The shape of the guide surface 2115 is designed to facilitate the sliding of the adjustment band 271 without causing significant wear to the adjustment band 271.

[0232] See you again Figure 39 In this embodiment, when the riding vehicle 200 is in the sleeping box state, the support plate 211 is tilted relative to the support frame 22. More specifically, in the sleeping box state, the distance between the front end of the support plate 211 and the support frame 22 is less than the distance between the rear end of the support plate 211 and the support frame 22. When the riding vehicle 200 is installed on the frame 100 and switched to the seat state, the support plate 211 is tilted at a certain angle to the horizontal plane, making it convenient for children to sit comfortably in the riding vehicle 200.

[0233] The following will refer to Figure 43 and Figure 44 To describe the passenger vehicle 200 according to the eighth embodiment of the present invention.

[0234] Figure 43 A side view of a passenger vehicle according to the eighth embodiment of the present invention is shown. Figure 44 It shows Figure 43 A perspective view of the seat plate. Unless otherwise specified, the structure of the passenger vehicle 200 can be referred to the description in the seventh embodiment. The following mainly describes the differences between this eighth embodiment and the seventh embodiment.

[0235] See Figure 43 and Figure 44In this embodiment, the protruding structure 218 is generally located in the middle of the bottom surface of the support plate 211 and extends along the front-to-back direction. The protruding structure 218 is generally arched (or arc-shaped) with a higher middle and lower front and rear ends. That is, the middle part of the protruding structure 218 is relatively far from the bottom surface of the support plate 211, while the front and rear ends of the protruding structure 218 are relatively far from the bottom surface of the support plate 211. When the vehicle 200 is placed on the plane H, even if the bottom surfaces of the protruding structure 218 and the seat plate 21 are in contact with the plane H at the same time, the vehicle 200 is still prone to swaying in the front-to-back and left-to-right directions.

[0236] See Figure 44 The protruding structure 218 is, for example, a separate structure from the base plate 21. The protruding structure 218 can be fixed to the bottom surface of the support plate 211 by means of a connector 2181. In some embodiments, the connector 2181 is, for example, L-shaped. The two perpendicular plates 21811 and 21812 of the L-shaped connector 2181 are fixedly connected to the protruding structure 218 and the support plate 211 respectively by fasteners 2183. The number of connectors 2181 can be set as needed.

[0237] In some alternative embodiments, the protruding structure 218 can be mounted on the bottom surface of the base plate 21 using other suitable structures. For example, the protruding structure 218 may have a skirt (or flange) through which multiple fasteners (e.g., screws) pass and connect to the support plate 211. Furthermore, in some alternative embodiments, the split protruding structure 218 may extend along the left-right or diagonal direction of the support plate 211, which is also within the scope of protection of this invention.

[0238] The following will refer to Figures 45 to 50 To describe the passenger vehicle 200 according to the ninth embodiment of the present invention.

[0239] Figure 45 and Figure 46 Perspective views of a passenger vehicle 200 according to a ninth embodiment of the present invention are shown from two different angles. Unless otherwise specified, the structure of the passenger vehicle 200 can be referred to the description in the eighth embodiment. The following mainly describes the differences between this ninth embodiment and the eighth embodiment.

[0240] See Figure 45 and Figure 46The riding vehicle 200 can be a deformable riding vehicle 200 capable of switching between a seat state and a bassinet state as described in the eighth embodiment, or it can be a non-deformable riding vehicle 200 that only has a bassinet state. In some examples of this utility model, the riding vehicle 200 may include a bassinet body 201A and an anti-misuse structure 202A. In some examples of this utility model, the anti-misuse structure 202A may be a protruding structure 218A. The bassinet body 201A may include a support frame 22, a seat plate 21, and a seat cloth 23 covering the support frame 22 and the seat plate 21. The seat plate 21 may include a support plate 211 and connecting arms 212 respectively disposed on the left and right sides of the support plate 211. When the riding vehicle 200 can be a deformable riding vehicle 200 capable of switching between a seat state and a bassinet state as described in the eighth embodiment, the support plate 211 may be as described in the eighth embodiment. Figure 44 The plate-like structure shown only covers the middle part of the bottom of the riding vehicle 200 and is only used to support the child's buttocks. When the riding vehicle 200 is a non-deformable riding vehicle 200 that only has a bassinet configuration, the support plate 211 can be a plate-like structure that covers the entire bottom of the riding vehicle 200 and can be used to support the child's entire body.

[0241] The following description uses a non-deformable vehicle 200 in its bassinet configuration as an example, where the support plate 211 can be a rectangular plate-like structure covering the entire bottom of the vehicle 200. Of course, in other embodiments, the support plate 211 can also be a plate-like structure of other shapes. For example... Figure 45 and Figure 46 As shown, in some examples of this utility model, 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 this utility model, the arc-shaped rod 218A can be located approximately in the middle of the bottom surface of the support plate 211 and extend along the front-rear direction. The arc-shaped rod 218A protrudes and bends away from the seat plate 21, that is, the middle part of the arc-shaped rod 218A is relatively far from the bottom surface of the support plate 211, while the front and rear ends of the arc-shaped rod 218A are relatively far from the bottom surface of the support plate 211. When the riding vehicle 200 is placed on a flat surface (not shown in the figure), even if the protruding structure 218A and the bottom surface of the seat plate 21 are simultaneously in contact with the flat surface H, the riding vehicle 200 is still prone to swaying in the front-rear and left-right directions.

[0242] See Figure 45 and Figure 46As shown, the arc-shaped rod 218A can be a separate structure from the support plate 211, for example. Two connecting rods 220A can be connected to the front and rear ends of the arc-shaped rod 218A, respectively. In some examples of this invention, the arc-shaped rod 218A and the two connecting rods 220A can be an integrally formed structure. In other embodiments, the arc-shaped rod 218A and the two connecting rods 220A can be separate structures, and the arc-shaped rod 218A and the two connecting rods 220A can be connected by, for example, welding or fasteners 25. The two connecting rods 220A can be fixed to the back of the support plate 211, for example, by fasteners 25 such as screws. In some examples of this invention, the seat cloth 23 can completely cover the bottom surface of the support plate 211, so 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, fasteners such as screws 25 can also be directly fixed to the back of the support plate 211.

[0243] In some alternative embodiments, the curved rod 218A may be located approximately at the center of the bottom surface of the support plate 211 and extend in a left-right or diagonal direction. In short, a good effect in preventing the vehicle 200 from lying flat is achieved when the projection of the curved rod 218A onto the seat plate 21 passes approximately through the geometric center of the support plate 211 (i.e., the intersection of the two diagonals of the support plate 211). Of course, in some embodiments, the projection of the curved rod 218A onto the seat plate 21 may also deviate from the geometric center of the support plate 211.

[0244] Additionally, when the riding vehicle 200 can be a deformable riding vehicle 200 capable of switching between a seat state and a bassinet state as described in the eighth embodiment, the arc-shaped rod 218A can, for example, be located generally in the middle of the bottom surface of the support plate 211 and extend in the left-right direction, and both ends of the arc-shaped rod 218A can be fixed to the support plate 211 by connecting rods 220A respectively; or, the arc-shaped rod 218A can also be located generally in the middle of the bottom surface of the support plate 211 and extend in the front-back direction, and both ends of the arc-shaped rod 218A can be fixed to the leg rest area 2311 and the backrest area 2313 of the seat fabric 23 by connecting rods 220A respectively.

[0245] Of course, there are many other ways to implement the protruding structure 218A, and it is not limited to the examples above. The number of protruding structures 218A is not limited to the number in this embodiment, as long as it can achieve the goal of unstablely supporting the vehicle 200 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, etc. In some embodiments, such as Figure 47 and Figure 48As shown, the protruding structure can also be a spherical crown-shaped structure 218B protruding downwards 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 crown-shaped structure may have a skirt (or flange) 220B. A plurality of fasteners 25 (e.g., screws) can pass through the skirt 220B and be connected to the support plate 211. In other embodiments, the spherical crown-shaped structure 218B may also be offset from the geometric center of the support plate 211. In other embodiments, such as Figure 49 and Figure 50 As shown, the protruding structure can also be an inverted conical structure 218C, etc., protruding downwards 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 inverted conical structure 218C has a skirt 220C (or flange), through which multiple fasteners 25 (e.g., screws) pass and connect to the support plate 211. In other embodiments, the inverted conical structure 218C may also be offset from the geometric center of the support plate 211.

[0246] The following will refer to Figure 51 and Figure 52 To describe the passenger vehicle 200 according to the tenth embodiment of the present invention.

[0247] Figure 51 A perspective view of a passenger vehicle 200 provided in the tenth embodiment of this utility model is shown. Figure 52 The diagram illustrates the structure of the anti-misuse structure 202A in the passenger vehicle 200 provided in the tenth embodiment of the present invention. Unless otherwise specified, the structure of this passenger vehicle 200 can be referred to the description in the ninth embodiment. The following mainly describes the differences between this tenth embodiment and the ninth embodiment.

[0248] See Figure 51 and Figure 52In some examples of this utility model, the anti-misuse structure 202A may be located approximately at the geometric center of the bottom surface of the support plate 211 (i.e., at the intersection of the two diagonals of the support plate 211). Of course, in other embodiments, the anti-misuse structure 202A may also be offset from the geometric center of the bottom surface of the support plate 211. Specifically, the anti-misuse structure 202A may include a fixing base 2181D, a push button 2182D, an alarm 2183D, and a fifth elastic reset member 2184D. The fixing base 2181D may be fixed to the geometric center of the bottom surface of the support plate 211, and may partially protrude from the bottom surface of the support plate 211 or be flush with the bottom surface of the support plate 211. The bassinet body 201A may be enclosed to form a receiving space 2010A for accommodating a child. In embodiments where the fixing seat 2181D is flush with the bottom surface of the support plate 211, the fixing seat 2181D can be fully embedded in the support plate 211, or it can be partially embedded in the support plate 211 and partially located within the receiving space 2010A. In some examples of this invention, the fixing seat 2181D is flush with the bottom surface of the support plate 211, and is partially embedded in the support plate 211 and partially located within the receiving space 2010A. A grooved soft pad (not shown in the figures) can be laid in the receiving space 2010A to avoid the fixing seat 2181D and improve the comfort of children. A 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 this invention, the fixing seat 2181D can be generally cylindrical in shape, and the fixing seat 2181D can have a mounting hole 21811D, which can be a blind hole. A first limiting protrusion 21812D may be provided around the edge of the hole wall of the mounting hole 21811D.

[0249] See some examples of this utility model. Figure 51 and Figure 52The push button 2182D may include a hemispherical button body 21821D, a second limiting protrusion 21822D surrounding 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 mounting base 2181D, the second limiting protrusion 21822D of the push button 2182D may be located within the mounting hole 21811D and may abut against the upper part of the first limiting protrusion 21812D. The cooperation between the first limiting protrusion 21812D and the second limiting protrusion 21822D can prevent the push button 2182D from dislodging from the mounting base 2181D. When the push button 2182D is mounted on the mounting base 2181D, the spherical surface of the button body 21821D may protrude downwards. The push button 2182D can be switched 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 can at least partially protrude from the fixing base 2181D, or protrude from the bottom surface of the support plate 211, and the push post 21823D can be spaced apart from the alarm 2183D. When the push button 2182D is in the second position, the button body 21821D can move towards the bottom of the mounting hole 21811D, and the push post 21823D can push against the alarm 2183D.

[0250] Further, see Figure 52 The alarm 2183D can be installed within the mounting base 2181D, specifically fixed to the top wall of the mounting hole 21811D. The alarm 2183D is adaptable to be pushed to trigger an alarm. In some examples of this invention, when the push button 2182D is in the second position, the push post 21823D of the push button 2182D can push the alarm 2183D to trigger an alarm, thereby alerting the caregiver to avoid placing the vehicle 200 flat on the ground or other flat surfaces. The alarm 2183D can be, for example, an alarm 2183D capable of emitting audible and visual alerts, or an alarm 2183D capable of sending alarm information to the caregiver's mobile communication device, etc. In short, any alarm function that can be provided is acceptable.

[0251] Further, see Figure 51The fifth elastic reset member 2184D can abut against the fixed base 2181D and the push button 2182D. The fifth elastic reset member 2184D is adapted to apply force to the push button 2182D to move it to the second position. In some examples of this utility model, two fifth elastic reset members 2184D can be provided. Both fifth elastic reset members 2184D can be springs and are respectively located on both sides of the push post 21823D. Taking one of the fifth elastic reset members 2184D as an example, one end of the fifth elastic reset 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 reset members 2184D abutting against the left and right ends of the button body 21821D, the movement of the button body 21821D can be made more stable.

[0252] Please see also Figure 23 , Figure 51 and Figure 52 When the ride-on device 200 is installed on the stroller, the push button 2182D on the support plate 211 is suspended, so it can be held in the first position by the elastic force of the fifth elastic reset member 2184D. The push post 21823D of the push button 2182D can be spaced apart from the alarm 2183D. When the ride-on device 200 is removed from the stroller and placed on a flat surface such as the ground, the button body 21821D of the push button 2182D can be pushed by the flat surface and moved towards the top wall of the mounting hole 21811D to the second position. The push post 21823D of the push button 2182D can push the alarm 2183D, causing the alarm 2183D to sound, reminding the caregiver not to place the ride-on device 200 on the flat surface.

[0253] The following will refer to Figures 53 to 58 The following describes a passenger vehicle 200 according to the eleventh embodiment of the present invention.

[0254] Figure 53 and Figure 54 The diagram shows a top perspective view and a side perspective view of the vehicle 200 provided in the eleventh embodiment of the present invention. Figure 55 This shows a partially enlarged view of the passenger vehicle 200 provided in the eleventh embodiment of the present invention. Figure 56 This diagram shows the structure of the vehicle 200 provided in the eleventh embodiment of the present invention after omitting the seat cloth 23 and the canopy 41; Figure 57 A partial enlarged view of a passenger vehicle in the prior art is shown; Figure 58A schematic diagram of the structure of a prior art passenger vehicle omitting the seat cover and canopy is shown. Unless otherwise specified, the structure of this passenger vehicle 200 can be referred to the description in the tenth embodiment. The following mainly describes the differences between this eleventh embodiment and the tenth embodiment.

[0255] See Figure 53 and Figure 54 In some examples of this utility model, the riding vehicle 200 may include a support frame 22, a seat plate 21, and a seat cover 23. The support frame 22 may be a rectangular annular frame structure. The seat plate 21 may be spaced apart from the support frame 22 and may be used to support a child. In some examples of this utility model, the seat plate 21 may only include the support plate 211, without including the connecting arms 212 respectively disposed on the left and right sides of the support plate 211. That is, in some examples of this utility model, the seat plate 21 and the support plate 211 may be the same component. Similarly, when the riding vehicle 200 is a deformable riding vehicle 200 capable of switching between a seat state and a bassinet state as described in the eighth embodiment, the support plate 211 may be as described in the eighth embodiment. Figure 44 The plate-like structure shown only covers the middle part of the bottom of the riding vehicle 200 and is only used to support the child's buttocks. When the riding vehicle 200 is a non-deformable riding vehicle 200 with only a bassinet configuration, the support plate 211 can be a plate-like structure covering the entire bottom of the riding vehicle 200 and can be used to support the entire body of the child. The opposite sides of the support frame 22 may each have a locking seat 219 that can engage with the mounting seat 19 of the frame 100. In some examples of this utility model, the two locking seats 219 may be specifically located on both sides of the long side of the support frame 22. The seat fabric 23 can cover the space between the support frame 22 and the seat plate 21, that is, the support frame 22 and the support plate 211 can be flexibly connected only by the seat fabric 23, such as... Figure 55 and Figure 56 As shown. In the prior art, for example, a space is often provided between the support frame 22 and the support plate 211, such as... Figure 57 and Figure 58 The rigid connector 24 shown, or the support frame 22 and support plate 211 are connected by a connecting arm 212 and a snap-fit ​​seat 219. However, in some examples of this invention, the support frame 22 and support plate 211 are only flexibly connected by a seat fabric 23, allowing the seat fabric 23 to switch between an unfolded and folded state to form an anti-misuse structure 202A. Please note that although similar or identical reference numerals are used herein for elements having similar functions and structures to those in this invention, such use is for illustrative purposes only and does not constitute an undue limitation on the specific features of the various embodiments of this invention.

[0256] In other examples, the support frame 22 can also be a ring frame structure of other shapes, such as a circular or elliptical ring frame structure, and the support plate 211 can be set as a circular or elliptical plate structure accordingly.

[0257] In other examples, the support frame 22 can also be a ring frame structure of other shapes, such as a circular or elliptical ring frame structure, and the support plate 211 can be set as a circular or elliptical plate structure accordingly.

[0258] When the riding vehicle 200 is mounted on the mounting seats 19 of the stroller frame 100 via the snap-fit ​​seats 219 on both sides, the mounting seats 19 exert an upward lifting force on the snap-fit ​​seats 219, while the weight of the child lying in the accommodating space 2010A exerts a downward force on the seat plate 21. This causes the support frame 22 and the seat plate 21 to move relatively apart, allowing the seat fabric 23 to be in an unfolded state. However, when the riding vehicle 200 is detached from the stroller frame 100, it loses the upward lifting force from the mounting seats 19 on the snap-fit ​​seats 219 and the downward force from the child's weight on the seat plate 21. This causes the support frame 22 and the seat plate 21 to move relatively closer together, and the seat fabric 23 to be folded up. In other words, the entire riding vehicle 200 collapses and becomes unusable. This design prevents the riding vehicle 200 from being placed on a flat surface.

[0259] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0260] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
