Description

Technical Field

[0001] This application relates to the field of children's vehicles, and more particularly, to passenger devices.

Background Art

[0002] A passenger device for children (e.g., a stroller) is a vehicle used by parents to carry infants and children when going shopping or window shopping. Currently, various folding strollers are commercially available, and they are easy to store and carry. To facilitate communication between the parents and the infant in the stroller, a stroller generally has a handlebar reversal mechanism. In some cases, after the reversal, the handlebar continues to rotate and drives the frame to fold simultaneously. Such a mechanism can make the operation of folding the stroller more convenient, but there is also a risk of accidental folding, posing a hidden danger to the safety of the child.

[0003] Generally, a stroller includes a seat and a frame for carrying the seat. When the seat and the frame are separable, the seat removed from the frame needs to be folded for easy storage. In this case, the armrest provided on the seat is also required to be folded synchronously. However, since the locking structure of the armrest and the locking structure during seat folding are different structures, the overall structure of the seat becomes complicated, making the manufacture and operation of the stroller difficult.

[0004] Furthermore, strollers generally feature a handlebar reversal mechanism, allowing the orientation of the infant inside the stroller to be adjusted as needed. For example, an infant may face their parent to interact with them, or they may face away from their parent to enjoy the scenery along the road. To facilitate the movement of the passenger device, generally, when the handlebars are on the rear wheel side, the rear wheels are directed while the front wheels are not directed, and when the handlebars are on the front wheel side, the front wheels are directed while the rear wheels are not. However, the structures required to implement such functions are generally complex, difficult to manufacture, and costly to produce. [Overview of the project]

[0054] In the passenger device of the present embodiment, when a user attempts to fold the frame, the user first operates the second locking member to unlock the handlebar. When the second locking member unlocks the handlebar, the second locking member simultaneously drives the third locking member to unlock the fixed seat. Next, the user operates the first locking member to unlock the first support member and the second support member. In this case, the user can fold the first support member and the second support member relative to each other. When the first support member and the second support member are folded relative to each other, the second support member simultaneously drives the link member to rotate the fixed seat relative to the frame and fold it, thereby achieving the folding of the frame. Furthermore, when the second locking member unlocks the handlebar, the user can reverse or fold the handlebar. In this case, the first support member and the second support member of the frame are still locked by the first locking member, and therefore, reversing or folding the handlebar may not lead to folding the frame. Furthermore, since the frame and the handlebar of the passenger device of the present invention fold relatively independently, the risk of the frame folding synchronously due to the handlebar can be prevented, thereby improving the safety of the passenger device. In addition, during folding, the frame may rotate and fold by driving the fixed seat, thereby reducing the volume of the passenger device after folding.

[0055] In the passenger device according to the embodiment of the present application, the armrest is in the usable position when the seat is in the unfolded state. When the seat of the stroller is in the folded state, the armrest can be folded synchronously. The stroller is simpler and easier to operate.

[0056] Furthermore, in the passenger device according to the embodiment of the present application, the handlebar may be rotated relative to the first or second travel assembly to realize a reversal function. When the handlebar is rotated to the same side as the first travel assembly, the orientation of the first wheel member and the deorientation of the second wheel member can be realized through the direction adjustment mechanism. When the handlebar is rotated to the same side as the second travel assembly, the orientation of the second wheel member and the deorientation of the first wheel member can be realized through the direction adjustment mechanism. That is, during the reversal of the handlebar, the direction adjustment function is realized between the first travel assembly, the second travel assembly, and the handlebar by the direction adjustment mechanism, thereby making it easier to push the passenger device after reversal. The direction adjustment function of the direction adjustment mechanism is mainly realized by the first drive block and the second drive block, which have a simple structure and are easy to implement. The passenger device can realize the function of adjusting the orientation of the wheel members while reversing the handlebar with a simple structure, thereby reducing the manufacturing cost of the passenger device.

[0061] Referring to Figures 1 to 7, Figure 1 is a perspective view of a passenger device 1 according to one embodiment of the present invention; Figure 2 is a perspective view of the passenger device in Figure 1 from a different viewpoint with the seat removed; Figure 3 is an exploded perspective view of the handlebar 14, second drive member 30, second lock member 16, second elastic member 34, and first support member 100; Figure 4 is a perspective view of the handlebar connecting seat 140 in Figure 3 from a different viewpoint; Figure 5 is an exploded perspective view of the link member 22, fixed seat 18, third elastic member 36, third lock member 20, and first support member 100; Figure 6 is a perspective view of the fixed seat 18 in Figure 5 from a different viewpoint; and Figure 7 is an exploded perspective view of the link member 22, second connecting seat 1020, first drive member 24, first lock member 12, first elastic member 28, and first support member 100.

[0062] As shown in Figures 1 to 7, the passenger device 1 according to the present invention comprises a frame 10, a first locking member 12, a handlebar 14, a second locking member 16, a fixed seat 18, a third locking member 20, a link member 22, a first drive member 24, a tensioning member 26, a first elastic member 28, a second drive member 30, a pull-out member 32, a second elastic member 34, a third elastic member 36, an operating member 38, and a seat 40. The passenger device 1 may also be a stroller or a device for other uses. The passenger device 1 according to the present invention has a substantially symmetrical structure, and the technical features of the structure of one side will be described below.

[0063] As shown in Figures 1 and 2, the frame 10 includes a first support member 100 and a second support member 102. The first support member 100 is pivotably connected to the second support member 102, thereby allowing the first support member 100 and the second support member 102 to rotate relative to each other so as to be folded or unfolded. In this embodiment, the first support member 100 may be the rear leg of the frame 10, and the second support member 102 may be the front leg of the frame 10, but is not limited to these. The first support member 100 may include a first connecting sheet 1000, and the second support member 102 may include a second connecting sheet 1020. The first connecting sheet 1000 is pivotably connected to the second connecting sheet 1020. The fixed sheet 18 is pivotably connected to the first connecting sheet 1000 of the first support member 100, thereby allowing the fixed sheet 18 to rotate relative to the first support member 100. The link member 22 is pivotably connected to the second connecting sheet 1020 of the second support member 102 and to the fixed sheet 18. Therefore, when the first support member 100 and the second support member 102 rotate relative to each other to fold or unfold, the second support member 102 can drive the link member 22 to rotate the fixed sheet 18 relative to the frame 10, causing it to fold or unfold.

[0064] As shown in Figure 3, in this embodiment, the handlebar 14 may include a handlebar connecting seat 140. The handlebar connecting seat 140 of the handlebar 14 is pivotably connected to the first connecting seat 1000 of the first support member 100, so that the handlebar 14 is rotatable relative to the first support member 100. The second locking member 16, the second driving member 30, and the second elastic member 34 are all positioned between the first connecting seat 1000 of the first support member 100 and the handlebar connecting seat 140 of the handlebar 14. As shown in Figure 4, the handlebar connecting seat 140 of the handlebar 14 has a second driving structure 142. The second driving member 30 is in contact with the second locking member 16 and the second driving structure 142 of the handlebar 14. The second elastic member 34 is in contact with the first connecting seat 1000 and the second locking member 16 of the first support member 100. In this embodiment, the second elastic member 34 may be a spring, but is not limited thereto.

[0065] As shown in Figures 3 and 4, the first connecting sheet 1000 of the first support member 100 may be provided with a third slot 1004, the handlebar connecting sheet 140 of the handlebar 14 may be provided with a fourth slot 1400, and the second locking member 16 may be provided with a second clamp portion 160. The second clamp portion 160 is clamped within the third slot 1004 and the fourth slot 1400 to lock the handlebar 14. It should be noted that the number and position of the third slot 1004, the fourth slot 1400, and the second clamp portion 160 may be determined according to the actual application.

[0066] As shown in Figure 1, an operating member 38 is movably mounted on the handlebar 14. One end of a pull-out member 32 is connected to the operating member 38, and the other end of the pull-out member 32 is connected to a second drive member 30 shown in Figure 3. Therefore, when the operating member 38 is pressed, it can pull out the pull-out member 32. When the pull-out member 32 is pulled, it can drive the second drive member 30 to move. In this embodiment, the operating member 38 may be a button, and the pull-out member 32 may be a steel wire, and is not limited to these.

[0067] As shown in Figure 5, the third locking member 20 and the third elastic member 36 are both positioned between the first connecting sheet 1000 and the fixing sheet 18 of the first support member 100. The third elastic member 36 is in contact with the third locking member 20 and the fixing sheet 18. In this embodiment, the third elastic member 36 may be a spring, but is not limited thereto. As shown in Figures 5 and 6, the first connecting sheet 1000 of the first support member 100 may be provided with a fifth slot 1006, the fixing sheet 18 may be provided with a sixth slot 180, and the third locking member 20 may be provided with a third clamp portion 200. The third clamp portion 200 is clamped within the fifth slot 1006 and the sixth slot 180 to lock the fixing sheet 18. It should be noted that the number and position of the fifth slot 1006, the sixth slot 180, and the third clamp portion 200 may be determined according to the actual application.

[0068] As shown in Figures 3 and 5, the second locking member 16 and the third locking member 20 are arranged on two sides of the first connecting sheet 1000 of the first support member 100. Furthermore, the first connecting sheet 1000 of the first support member 100 is provided with a through hole 1008, and the second locking member 16 may be provided with a push rod 162. The push rod 162 is inserted into the through hole 1008.

[0069] As shown in Figure 7, the first locking member 12, the first driving member 24, and the first elastic member 28 are all positioned between the first connecting sheet 1000 of the first support member 100 and the second connecting sheet 1020 of the second support member 102. In this embodiment, a first driving structure (not shown) may be provided on the inner surface of the second connecting sheet 1020 of the second support member 102. The first driving structure is substantially the same as the second driving structure 142 in Figure 4. The first driving member 24 is in contact with the first locking member 12 and the first driving structure of the second support member 102. The first elastic member 28 is in contact with the first connecting sheet 1000 of the first support member 100 and the first locking member 12. In this embodiment, the first elastic member 28 may be a spring, but is not limited thereto.

[0070] As shown in Figure 7, a first slot 1002 is provided in the first connecting sheet 1000 of the first support member 100, a second slot (not shown) is provided on the inner surface of the second connecting sheet 1020 of the second support member 102, and a first clamp portion 120 may be provided on the first locking member 12. The second slot is substantially the same as the fourth slot 1400 in Figure 4. The first clamp portion 120 clamps within the first slot 1002 and the second slot to lock the first support member 100 and the second support member 102. It should be noted that the number and position of the first slot 1002, the second slot, and the first clamp portion 120 may be determined according to the actual application. Furthermore, the tensioning member 26 shown in Figure 2 extends into the second connecting sheet 1020 of the second support member 102 and is connected to the first drive member 24. In this embodiment, the tensioning member 26 may be a braided cord, but is not limited thereto.

[0071] The operating principle of the present invention will now be explained with reference to the elements shown in Figures 1 to 7.

[0072] When the passenger device 1 is in the deployed state shown in Figure 1, the first locking member 12 locks the first support member 100 and the second support member 102, the second locking member 16 locks the handlebar 14, and the third locking member 20 locks the fixed seat 18. In this case, the first support member 100, the second support member 102, the handlebar 14, and the fixed seat 18 are immobile. When a user wants to reverse or fold the handlebar 14, the user can press the operating member 38. In this case, the operating member 38 pulls the pull-out member 32, which in turn drives the second drive member 30 to move it. As shown in Figures 3 and 4, the second drive member 30 and the second drive structure 142 have inclined surfaces that abut each other. Therefore, when the pull-out member 32 is driven to move the second drive member 30, the second drive structure 142 pushes the second drive member 30 toward the second locking member 16, and the second drive member 30 pushes the second locking member 16 toward the first connecting seat 1000 of the first support member 100, thereby causing the second clamp portion 160 of the second locking member 16 to disengage from the fourth slot 1400 of the handlebar 14. In this way, the second locking member 16 unlocks the handlebar 14. In this case, the user can rotate the handlebar 14 to reverse or fold it. In this case, the first support member 100 and the second support member 102 of the frame 10 are still locked by the first locking member 12, and therefore, reversing or folding the handlebar 14 does not necessarily lead to folding the frame 10.

[0073] When the second drive member 30 pushes the second locking member 16 toward the first connecting seat 1000 of the first support member 100, the second locking member 16 can compress the second elastic member 34. When the second clamp portion 160 of the second locking member 16 is realigned with the fourth slot 1400 of the handlebar 14, the second elastic member 34 may push the second locking member 16 so that the second locking member 16 is reset.

[0074] Furthermore, when the second drive member 30 pushes the second locking member 16 toward the first connecting seat 1000 of the first support member 100, the push rod 162 of the second locking member 16 pushes the third locking member 20 toward the fixed seat 18, thereby causing the third clamp portion 200 of the third locking member 20 to disengage from the fifth slot 1006 of the first support member 100, and thus unlocking the fixed seat 18. In other words, when the second locking member 16 unlocks the handlebar 14, the second locking member 16 can drive the third locking member 20 to unlock the fixed seat 18.

[0075] When the push rod 162 of the second locking member 16 pushes the third locking member 20 toward the fixing sheet 18, the third locking member 20 can compress the third elastic member 36. When the second locking member 16 is reset, the third elastic member 36 pushes the third locking member 20, thereby resetting the third locking member 20.

[0076] When a user attempts to fold the frame 10, the user can further pull the tension member 26. When the tension member 26 is pulled, it can drive the first drive member 24 to move. In this embodiment, the first drive member 24 and the first drive structure of the second support member 102 (the first drive structure is substantially the same as the second drive structure 142 in Figure 4) may have inclined surfaces that abut each other. Therefore, when the tension member 26 drives the first drive member 24 to move, the first drive structure pushes the first drive member 24 toward the first lock member 12, and the first drive member 24 pushes the first lock member 12 toward the first connecting sheet 1000 of the first support member 100, thereby causing the first clamp portion 120 of the first lock member 12 to disengage from the second support member 102. In this way, the first lock member 12 unlocks the first support member 100 and the second support member 102.

[0077] When the third locking member 20 unlocks the fixed sheet 18, and the first locking member 12 unlocks the first support member 100 and the second support member 102, the first support member 100 and the second support member 102 can rotate relative to each other and fold, thereby causing the second support member 102 to drive the link member 22, which in turn causes the fixed sheet 18 to rotate relative to the frame 10 and fold.

[0078] When the first drive member 24 pushes the first locking member 12 toward the first connecting sheet 1000 of the first support member 100, the first locking member 12 can compress the first elastic member 28. When the first clamp portion 120 of the first locking member 12 is realigned with the second slot of the second support member 102, the first elastic member 28 may push the first locking member 12, thereby resetting the first locking member 12.

[0079] As shown in Figure 1, the sheet 40 is detachably positioned on the fixed sheet 18. Therefore, when the fixed sheet 18 is rotated relative to the frame 10 and folded, the sheet 40 may also be rotated and folded together with the fixed sheet 18.

[0080] Referring to Figures 8 to 10, Figure 8 is a side view of the passenger device 1 in Figure 1, Figure 9 is a side view showing the handlebars 14 and seat 40 in Figure 8 folded, and Figure 10 is a side view showing the frame 10 in Figure 9 folded.

[0081] As shown in Figures 8 to 10, the user can first fold the handlebars 14 according to the operation described above. The frame 10 remains unfolded even after the handlebars 14 are folded. Next, the user can fold the seat 40. After the handlebars 14 and seat 40 are folded, the user can again fold the frame 10 according to the operation described above. While the frame 10 is being folded, the frame 10 may synchronously drive the seat 40 to fold as well.

[0082] Referring to Figures 11 to 13, Figure 11 is a side view showing that the handlebar 14 of the passenger device 1 in Figure 1 is inverted, Figure 12 is a side view showing that the handlebar 14 and seat 40 in Figure 11 are folded, and Figure 13 is a side view showing that the frame 10 in Figure 12 is folded.

[0083] As shown in Figures 11 to 13, the user can first invert the handlebars 14 and then fold them according to the manner of operation described above. The frame 10 remains unfolded even when the handlebars 14 are folded. Next, the user can fold the seat 40. After the handlebars 14 and seat 40 are folded, the user can again fold the frame 10 according to the manner of operation described above. While the frame 10 is being folded, the frame 10 may synchronously drive the seat 40 to fold as well.

[0084] In another embodiment, in the present invention, the handlebar 14 may be foldable when in the state shown in Figure 8, and may not be foldable when in the state shown in Figure 11. Furthermore, when the handlebar 14 is in the state shown in Figure 8, the user may fold the handlebar 14 to the state shown in Figure 9. When the user switches the handlebar 14 from the state shown in Figure 8 to the state shown in Figure 11, the handlebar 14 cannot be folded by the user to the state shown in Figure 12.

[0085] Therefore, in the present invention, the handlebar 14 can be selectively made foldable or non-foldable when in the state shown in Figure 11, depending on the actual use.

[0086] Referring to Figures 14 to 16, Figure 14 is a perspective view of a passenger device 1 according to another embodiment of the present invention, Figure 15 is a partial cross-sectional view of the passenger device 1 in Figure 14, and Figure 16 is a cross-sectional view showing the upper handlebar 144 in Figure 15 sliding to its lowest position relative to the lower handlebar 146.

[0087] As shown in Figures 14 to 16, the passenger device 1 may further include an operating member 42, a pushing member 44, a rotating member 46, a connecting member 48, and a clamping member 50, and the handlebar 14 may include an upper handlebar 144 and a lower handlebar 146. The lower handlebar 146 is pivotably connected to the first connecting seat 1000 of the first support member 100, and the lower end 1440 of the upper handlebar 144 is retractably inserted into the lower handlebar 146. The pushing member 44 is located at the lower end 1440 of the upper handlebar 144. The operating member 42 is slidably located on the upper handlebar 144. The rotating member 46 is rotatably located on the lower handlebar 146. The two ends of the connecting member 48 are connected to the operating member 42 and the clamping member 50, respectively. The lower handlebar 146 is provided with a plurality of clamping holes 1460. The clamp member 50 is clamped into one of the multiple clamp holes 1460 to lock the upper handlebar 144. The operating member 42 is operable, which drives the clamp member 50 away from the clamp hole 1460 by the connecting member 48, thereby allowing the upper handlebar 144 to slide against the lower handlebar 146 and adjusting the length of the handlebar 14. In this embodiment, the user may pull the operating member 42 upward, thereby driving the clamp member 50 away from the clamp hole 1460 by the connecting member 48. The user can then slide the upper handlebar 144 upward or downward against the lower handlebar 146 and clamp the clamp member 50 into the corresponding clamp hole 1460 to adjust the length of the handlebar 14.

[0088] As shown in Figures 15 and 16, the two ends of the pull-out member 32 may be connected to a rotating member 46 and a second drive member 30, respectively. As described above, the operating member 42 is operable to slide the upper handlebar 144 relative to the lower handlebar 146. As shown in Figure 16, when the upper handlebar 144 slides to its lowest position relative to the lower handlebar 146, the pushing member 44 may push one end of the rotating member 46 to rotate in the direction indicated by arrow A1, thereby causing the other end of the rotating member 46 to pull the pull-out member 32 in the direction indicated by arrow A2, and unlocking the lower handlebar 146 of the handlebar 14. In this case, the user can rotate the handlebar 14 to reverse or fold it. It should be noted that the unlocking structure and operating principle of the handlebar 14 have been described above and will not be described again in detail herein.

[0089] Therefore, according to the above technical solution, the passenger device according to the present invention has at least the following advantages and beneficial effects. That is, when the user wants to fold the frame, the user must first operate the second locking member to unlock the handlebars. When the second locking member unlocks the handlebars, the second locking member can simultaneously drive the third locking member to unlock the fixed seat. Next, the user operates the first locking member to unlock the first support member and the second support member. In this case, the user can fold the first support member and the second support member relative to each other. When the first support member and the second support member are folded relative to each other, the second support member can simultaneously drive the link member to rotate the fixed seat relative to the frame and fold it, thereby realizing the folding of the frame. Furthermore, when the second locking member unlocks the handlebar, the user can reverse or fold the handlebar. In this case, the first and second support members of the frame remain locked by the first locking member, and therefore, reversing or folding the handlebar may not lead to folding the frame. In addition, since the frame and handlebar of the passenger device of the present invention fold relatively independently, the risk of the frame folding synchronously due to the handlebar can be prevented, thereby improving the safety of the passenger device. Furthermore, during folding, the frame may rotate and fold by driving the fixed seat, thereby reducing the volume of the passenger device after folding.

[0090] As shown in Figure 17, the seat 40 of the passenger device 1 according to an embodiment of the present invention includes an upper framework 81, a lower framework 82, and an armrest 83. The upper framework 81, the lower framework 82, and the armrest 83 are rotatably connected via an armrest folding mechanism, so that the three can rotatably fold relative to each other.

[0091] Figure 18 shows an armrest folding mechanism according to the present invention, which includes a first connecting member 810, a second connecting member 820, and a third connecting member 830, these connecting members being connected via a connecting shaft 840 (shown in Figure 23) so as to be rotatable relative to each other around a central axis.

[0092] The first connecting member 810 is connected to the upper framework 81, the second connecting member 820 is connected to the lower framework 82, and the third connecting member 830 is connected to the armrest 83. Since the first connecting member 810, the second connecting member 820, and the third connecting member 830 are rotatable relative to each other, the upper framework 81, the lower framework 82, and the armrest 83, to which they are connected, are swivelable relative to each other. Such connections may be fixed or detachable. For example, in the embodiment of Figure 3, the first connecting member 810 extends from the first connecting portion 811 and is fixedly connected to the upper framework 81. The second connecting member 820 extends from the second connecting portion 821 and is fixedly connected to the lower framework 82. A connecting groove 831 is provided on the outer end surface of the third connecting member 830, facing away from the second connecting member 820, and is detachably connected to the armrest 83. However, the present invention is not limited thereto.

[0093] Furthermore, although the first connecting member 810, the second connecting member 820, and the third connecting member 830 are shown as disc-shaped, other shapes are also possible.

[0094] The following describes in detail how the seat 40 is switched between an unfolded state and a folded state via the armrest folding mechanism of the present invention, and how the seat 40 is maintained in the unfolded state.

[0095] To achieve the above-described functions, the upper framework 81 and lower framework 82 of the seat 40 are required to be able to pivot relative to each other and maintain a pivot angle such as 180°, as shown in Figures 17 to 20. That is, the first connecting member 810 and the second connecting member 820 are required to be able to rotate relative to each other and to be able to lock each other without rotating. For this reason, as shown in Figure 19, the first connecting member 810 is connected to a clamp member 812. The clamp member 812 is movable between a locked position and an unlocked position relative to the first connecting member 810, but cannot rotate relative to the first connecting member 810. The clamp member 812 includes a protrusion 8120. Correspondingly, the second connecting member 820 includes a first chute 822 that curves and extends around a central axis, and a clamp hole 823 that communicates with one end of the first chute 822. The protrusion 8120 is insertable into the clamp hole 823 and slidable along the first chute 822, as shown in Figures 20 and 21. The extension radian of the first chute 822 can be approximately 180° or slightly less than 180°, thereby allowing the upper framework 81 connected to the first connecting member 810 and the lower framework 82 connected to the second connecting member 820 to fold relative to each other as much as possible.

[0096] As shown in Figure 21, the radial width W823 of the clamp hole 823 is greater than the radial width W822 of the first chute 822, and the radial width W823 of the clamp hole 823 is configured to allow the clamp member 812 to move radially between a locked position and an unlocked position after the protrusion 8120 is inserted into the clamp hole 823, thereby allowing the clamp member 812 to lock and unlock the relative rotation of the first connecting member 810 and the second connecting member 820.

[0097] Specifically, as shown in Figure 20, when the clamp member 812 is shifted to the locked position, the protrusion 8120 is positioned within the clamp hole 823 and deviates from the first chute 822, preventing it from entering the first chute 822. This prevents relative rotation between the first connecting member 810 and the second connecting member 820. In this case, the sheet 40 is maintained in the unfolded state, as shown in Figure 24.

[0098] When the clamp member 812 is shifted to the unlocked position, as shown in Figure 21, the protrusion 8120 moves to a position within the clamp hole 823 that is aligned with the first chute 822, enters the first chute 822 and becomes slidable, thereby allowing relative rotation between the first connecting member 810 and the second connecting member. In this case, the sheet 40 can be switched between an unfolded state and a folded state, as shown in Figures 25 and 26.

[0099] In the present invention, the clamp member 812 can be arranged on the first connecting member 810 in various common forms. For example, a guide rail for guiding the clamp member 812 may be arranged on the side end face of the first connecting member 810. Alternatively, the clamp member 812 may be provided with two elongated slot holes through which the two elongated slot holes guide the movement of the clamp member 812. One of the elongated holes may allow the connecting shaft 840 to pass through, and the other elongated hole may allow a pin for connecting the clamp member 812 to the first connecting member 810 to pass through. Alternatively, the clamp member 812 may be provided with only one elongated slot hole through which the connecting shaft 840 passes, and the first connecting member 810 may be provided with the other elongated slot hole through which a pin for connecting the clamp member 812 to the first connecting member 810 to pass.

[0100] In the present invention, the shift of the clamp member 812 relative to the first connecting member 810 can be achieved in various general forms. For example, the clamp member 812 has an operating lever (not shown) extending from the armrest folding mechanism. The clamp member 812 is shifted by moving the operating lever. The armrest folding mechanism further comprises a fourth elastic member 813. The fourth elastic member 813 drives the clamp member 812 to shift to the locked position. The fourth elastic member 813 may be a compression spring, a leaf spring, an elastic body, etc. In the preferred embodiment shown in Figure 19, the fourth elastic member 813 is disposed on the first connecting member 810, but it should be understood that the fourth elastic member may be disposed on other parts of the armrest folding mechanism. For example, if the clamp member is disposed on the second connecting member 820, the fourth elastic member may be disposed on the second connecting member 820. More preferably, the armrest folding mechanism further comprises a second unlocking member 814. The second unlocking member 814 is operable to drive the clamping member 812 to shift it to the unlocked position. To facilitate folding the seat, the second unlocking member 814 may be a steel wire. This steel wire has one end connected to the clamping member 812 and the other end connected to an operating unit 84 located on the upper framework 81. In this way, when the user operates the operating unit 84, the steel wire is pulled, driving the clamping member 812 connected to one end of the steel wire to move. Of course, the present invention is not limited thereto.

[0101] The following will describe in detail how the armrest 83 of the seat 40 is folded synchronously and held in the use position by the armrest folding mechanism of the present invention.

[0102] To achieve this functionality, the armrest 83 of the seat 40 is rotatable relative to the upper framework 81 and the lower framework 82, and can maintain its rotatable angle. That is, the third connecting member 830 is rotatable relative to the first connecting member 810 and the second connecting member 820, and can lock together without rotating. For this purpose, as is best observed in Figure 22, the side end face of the third connecting member 830 facing the second connecting member 820 is also provided with a second chute 824 that curves and extends around a central axis, and a positioning hole 825 that communicates with one end of the second chute 824. The projection 8120 of the clamp member 812 can also be inserted into the positioning hole 825 and slid along the second chute 824. The extended radian of the second chute 824 may be equal to or less than the extended radian of the first chute 822, but preferably greater than the angle from the armrest 83 to the lower framework 82 in the deployed state, thereby allowing the armrest 83 connected to the third connecting member 830 and the lower framework 82 connected to the second connecting member 820 to fold as relative to each other as possible.

[0103] The radial positions of the first chute 822 and the second chute 824 correspond to each other, and the radial positions of the clamp hole 823 and the positioning hole 825 also correspond to each other. Furthermore, as shown in Figure 22, the radial width W825 of the positioning hole 825 is larger than the radial width W824 of the second chute 824, and the radial width W825 of the positioning hole 825 is configured to allow the clamp member 812 to move radially between a locked position and an unlocked position after the protrusion 8120 is inserted into the positioning hole 825. This also allows the clamp member 812 to lock and unlock the relative rotation between the third connecting member 830, the first connecting member 810, and the second connecting member 820.

[0104] Specifically, when the clamp member 812 is shifted to the locked position, the protrusion 8120 moves to a position within the positioning hole 825 and deviates from the second chute 824, preventing it from entering the second chute 824. This prevents relative rotation between the third connecting member 830, the first connecting member 810, and the second connecting member 820. In this case, the armrest 83 connected to the third connecting member 830 is held in the use position, as shown in Figure 24.

[0105] When the clamp member 812 is moved to the unlocked position, the protrusion 8120 moves to a position within the positioning hole 825 that is aligned with the second chute 824, and enters the second chute 824, becoming slidable. This allows relative rotation between the third connecting member 830, the first connecting member 810, and the second connecting member 820. In this case, the armrest 83 connected to the third connecting member 830 can be folded synchronously, as shown in Figures 25 and 26.

[0106] With the above settings, the armrest folding mechanism according to the present invention can achieve the following: when the seat 40 is in the unfolded state, the armrest 83 is in the usable position, and when the seat 40 is in the folded state, the armrest 83 folds synchronously. Furthermore, the structure of the armrest folding mechanism according to the present invention is simpler and easier to operate.

[0107] The armrest folding mechanism according to the present invention has been described above based on an example in which the clamp member 812 is connected to the first connecting member 810, but the present invention is not limited thereto. In a modified embodiment, the clamp member may be connected to the second connecting member 820. In that modified embodiment, the structures of the first connecting member 810 and the second connecting member 820 are changed, while the structure of the third connecting member 830 remains unchanged.

[0108] Specifically, the clamp member is connected to either side of the second connecting member 820, and the clamp member is movable between a locked position and an unlocked position relative to the second connecting member 820, but may not be rotatable relative to the second connecting member 820. The clamp member includes protrusions that project toward two sides of the second connecting member 820. Furthermore, the second connecting member 820 is provided with via holes through which the protrusions pass, so that the protrusions of the clamp member can pass through the first connecting member 810 and the third connecting member 830, regardless of which side of the second connecting member 820 is connected to the clamp member.

[0109] In response to this, the first connecting member 810 includes a first connecting member chute that extends in a curve around a central axis, and a first connecting member clamp hole that communicates with one end of the first connecting member chute.

[0110] The radial positions of the first connecting member chute of the first connecting member 810 and the second chute of the third connecting member 830 correspond to each other, and the radial positions of the first connecting member clamp hole of the first connecting member 810, the via hole of the second connecting member 820, and the positioning hole of the third connecting member 830 also correspond to each other. Furthermore, the protruding portion can pass through the first connecting member clamp hole and the positioning hole and is slidable along the first connecting member chute and the second chute.

[0111] The radial widths of the first connecting member clamp hole, via hole, and positioning hole are greater than the radial widths of the first connecting member chute and the second chute, and the clamp member is configured to be able to shift radially between the locked position and the unlocked position, thereby allowing and preventing the rotation of the first connecting member 810, the second connecting member 820, and the third connecting member 830 relative to each other.

[0112] Several special embodiments of the armrest folding mechanism according to the present invention are described below. Such embodiments can facilitate more reliable and convenient use of the stroller.

[0113] In one embodiment, to enhance the positioning of the armrest 83 in use, a reinforcing bulge 832 is positioned on the periphery of the third connecting member 830, as shown in Figure 27, and a contact surface 826 is positioned at a corresponding location on the periphery of the second connecting member 820. When the armrest 83 is used as a handle and pulled upward, the reinforcing bulge 832 contacts the contact surface 826, restricting the rotation of the third connecting member 830 relative to the second connecting member 820, thereby enhancing the positioning of the armrest 83.

[0114] In another embodiment, if the seat 40 and the frame 10 are separable, the armrest folding mechanism may include an adapter 850 for easily positioning the seat 40 on the frame 10 and easily removing the seat 40 from the frame 10. The adapter 850 is fixed to the first connecting member 810 and is engageable with a fixed seat 18 positioned on the frame 10, as shown in Figures 28 and 29, thereby allowing the seat to be detachably positioned on the frame.

[0115] To prevent the risk of the seat 40 separating from the frame 10 due to the accidental detachment of the adapter 850 from the fixing seat 18, the adapter 850 may be provided with a locking member 526, such as a hook 5262, and the fixing seat 18 may be provided with a clamping structure, such as a clamping bulge 181, that engages with the locking member 526. Alternatively, the reverse configuration is also possible, namely, the adapter 850 may be provided with a clamping bulge 181 and the fixing seat 18 may be provided with a hook 5262. The hook 5262 is capable of engaging with or disengaging from the clamping bulge 181, thereby preventing the adapter 850 from being removed from the fixing seat 18 or allowing the adapter 850 to be removed from the fixing seat 18.

[0116] In the embodiments shown in Figures 28 and 29, the hook 5262 is rotatable so as to engage with or disengage from the clamping bulge 181. However, the present invention is not limited thereto. Alternatively, the hook 5262 may be movable from side to side, or the clamping bulge 181 may be movable, thereby enabling engagement or disengagement between them.

[0117] To facilitate operation, the adapter 850 may further include a fifth elastic member 851. The fifth elastic member 851 drives the hook 5262 to engage with the clamping bulge 181. The fifth elastic member 851 may be a stretch spring, a leaf spring, an elastic body, or the like.

[0118] In a more preferred embodiment, the adapter 850 further comprises a first release member 524, which is, for example, a button. The first release member 524 can be pressed to drive the hook 5262 to disengage from the clamping bulge 181. Of course, the present invention is not limited thereto. The adapter 850 may further comprise other operating members, as long as they are capable of driving the hook 5262 to disengage from the clamping bulge 181.

[0119] In another embodiment according to this application, as shown in Figures 30 to 32, the adapter 850 includes a first seat body 520, a second seat body 522, a first unlocking member 524, and a locking member 526. The first seat body 520 is connected to the second seat body 522. The first seat body 520 is configured to connect a vehicle. The vehicle may be a safety seat, a baby crib, or other infant vehicle, depending on the actual application. The user can place the second seat body 522 of the adapter 850 on the fixed seat 18 and then connect the vehicle to the first seat body 520. In this way, the vehicle can be placed on the frame 10 of the passenger device 1 via the adapter 850.

[0120] As shown in Figures 30 to 32, the locking member 526 is rotatably positioned on the second seat body 522, and the first unlocking member 524 is movably positioned on the second seat body 522. The first unlocking member 524 has a guide portion 5240, and the locking member 526 has an oblique slot 5260 and a hook 5262. The guide portion 5240 of the first unlocking member 524 is positioned within the oblique slot 5260 of the locking member 526. When the second seat body 522 of the adapter 850 is positioned on the fixed seat 18 shown in Figure 2, the hook 5262 of the locking member 526 engages with the clamp structure (e.g., clamping bulge 181) of the fixed seat 18. When a user wants to remove the adapter 850, the user can press the first unlocking member 524. When the first release member 524 is pressed, the guide portion 5240 of the first release member 524 pushes the diagonal slot 5260 of the locking member 526, driving the locking member 526 to rotate, thereby allowing the hook 5262 of the locking member 526 to disengage from the clamping structure of the fixing sheet 18. In this way, the user can easily remove the adapter 850.

[0121] As shown in Figures 33 to 35 and Figure 50, one embodiment of the present invention proposes a passenger device including a first travel assembly 300, a second travel assembly 400, a handlebar 14, a direction adjustment mechanism 600, and a drift drive mechanism 700. This passenger device can implement the function of adjusting the direction of the wheels while reversing the handlebar with a simple structure, thereby reducing the manufacturing cost of the passenger device.

[0122] Specifically, as shown in Figures 33, 44, and 45, the first running assembly 300 includes a second support member 102, a first wheel member 320, a first directional mechanism 330, and a first rotating shaft 340.

[0123] As shown in Figures 33, 44, and 45, the second support member 102 is swivelably connected to the first wheel member 320. Specifically, one end of the first rotating shaft 340 is fixed to the second support member 102, and the first wheel member 320 is swivelably connected to the other end of the first rotating shaft 340. Of course, in other embodiments, one end of the first rotating shaft 340 may be fixed to the first wheel member 320, and the second support member 102 may be swivelably connected to the other end of the first rotating shaft 340; these are not limitations. The first wheel member 320 includes a first wheel mount 321 and a first wheel body 322. The first wheel mount 321 is swivelably connected to the second support member 102. The first wheel body 322 is rotatably mounted on the first wheel mount 321.

[0124] As shown in Figures 33, 44, and 45, the first directional mechanism 330 includes a first directional pin 331 movably positioned on the second support member 102 and a first directional groove 332 positioned on the first wheel mount 321. The first directional pin 331 is inserted into the first directional groove 332 to lock the first directional mechanism 330. In this case, the first wheel member 320 is held in a certain direction relative to the second support member 102. The first directional pin 331 is pulled away from the first directional groove 332 to unlock the first directional mechanism 330. In this case, the first wheel member 320 is rotatable 360 ​​degrees relative to the second support member 102. Of course, the first directional mechanism 330 may take other forms, as long as it can be locked to directional the first wheel member 320 and unlocked to undirectional the first wheel member 320.

[0125] Specifically, as shown in Figures 33, 42, and 43, the second running assembly 400 includes a first support member 100, a second wheel member 419, a second directional mechanism 430, and a second rotating shaft 440.

[0126] As shown in Figures 33, 42, and 43, the first support member 100 is swivelably connected to the second wheel member 419. Specifically, one end of the second rotating shaft 440 is fixed to the first support member 100, and the second wheel member 419 is swivelably connected to the other end of the second rotating shaft 440. Of course, in other embodiments, one end of the second rotating shaft 440 may be fixed to the second wheel member 419, and the first support member 100 may be swivelably connected to the other end of the second rotating shaft 440. The second wheel member 419 includes a second wheel mount 421 and a second wheel body 422. The second wheel mount 421 is swivelably connected to the first support member 100. The second wheel body 422 is rotatably mounted to the second wheel mount 421.

[0127] As shown in Figures 33, 42, and 43, the second directional mechanism 430 includes a second directional pin 431 movably positioned on the first support member 100 and a second directional groove 432 positioned on the second wheel mount 421. The second directional pin 431 is inserted into the second directional groove 432 to lock the second directional mechanism 430. In this case, the second wheel member 419 is held in a certain direction relative to the first support member 100. The second directional pin 431 is pulled away from the second directional groove 432 to unlock the second directional mechanism 430. In this case, the second wheel member 419 is rotatable 360 ​​degrees relative to the first support member 100. Of course, the second directional mechanism 430 may take other forms, as long as it can be locked to directional the second wheel member 419 and unlocked to undirectional the second wheel member 419.

[0128] In this embodiment, as shown in Figure 33, one end of the second support member 102, which is away from the first wheel member 320, is rotatably connected to one end of the first support member 100, which is away from the second wheel member 419.

[0129] Specifically, as shown in Figures 33 to 37, the handlebar 14 includes a handlebar body 410 and a handlebar mount 420 that are connected to each other. The handlebar body 410 is substantially rod-shaped, and the handlebar mount 420 is substantially disc-shaped. The handlebar 14 is rotatable relative to the first travel assembly 300 or the second travel assembly 400 to change the direction of travel of the passenger device. For example, when the handlebar 14 is rotated to the same side as the first travel assembly 300, the passenger device moves along the second direction D2 in Figure 38. When the handlebar 14 is rotated to the same side as the second travel assembly 400, the passenger device moves along the sixth direction D6 in Figure 40.

[0130] Specifically, as shown in Figures 33 to 45, a direction adjustment mechanism 600 is positioned between the first running assembly 300, the second running assembly 400, and the handlebar 14. As shown in Figures 38 and 39, the handlebar 14 is rotated to the same side as the first running assembly 300, and the direction adjustment mechanism 600 is driven to orient the first wheel member 320 and de-orient the second wheel member 419. As shown in Figures 40 and 41, the handlebar 14 is rotated to the same side as the second running assembly 400, and the direction adjustment mechanism 600 is driven to orient the second wheel member 419 and de-orient the first wheel member 320.

[0131] In this embodiment, as shown in Figures 38 to 45, the orientation adjustment mechanism 600 may include a fixed shell 610, a first drive block 621, a second drive block 622, a first drive rib 631, a second drive rib 632, a first traction member 641, a second traction member 642, a first reset member 651, a second reset member 652, a third reset member 653, and a fourth reset member 654.

[0132] Specifically, as shown in Figures 33 to 35, the fixed shell 610 includes a first connecting seat base 10001, a first connecting seat housing 10002, and a second connecting seat 1020. The first connecting seat base 10001 is pivotably connected to the first travel assembly 300, and the first connecting seat housing 10002 is fixed to the second travel assembly 400. The first connecting seat base 10001 and the first connecting seat housing 10002 enclose the first connecting seat 1000 in a accommodating space. The first connecting seat base 10001 has a substantially elliptical seat structure. The first connecting seat housing 10002 includes a housing body 10002a and a housing connecting member 10002b that are connected to each other. The housing body 10002a has an elliptical structure that matches the first connecting seat base 10001. The housing connecting member 10002b is substantially bush-shaped to encircle one end of the first support member 100, which is away from the second wheel member 419. The second connecting seat 1020 is fixed to one end of the second support member 102, which is away from the first wheel member 320. The second connecting seat 1020 is provided with a pivot 613a. The pivot 613a sequentially passes through the first connecting seat base 10001 and the housing body 10002a, realizing a coaxially rotatable connection of these three. Referring also to Figure 39, the second connecting seat 1020, the first connecting seat base 10001 and the housing body 10002a are rotatably connected to the first pivot point M. The handlebar 14 is rotatably connected to the side of the first connecting seat housing 10002, which faces away from the first connecting seat base 10001. The handlebar 14 and the first connecting seat housing 10002 are rotatably connected to the second pivot point N. The first connecting seat housing 10002 includes a first guide column 10001a and a second guide column 10001b. Of course, in other embodiments, the first guide column 10001a and the second guide column 10001b may also be located on the first connecting seat base 10001. In this embodiment, the first pivot point M is located in a first direction D1 of the second pivot point N.The first guide column 10001a and the second guide column 10001b are located between the first pivot point M and the second pivot point N.

[0133] In this embodiment, the second connecting sheet 1020 is made of a plastic material. Of course, in other embodiments, the second connecting sheet 1020 may be made of other materials.

[0134] Furthermore, as shown in Figures 38 to 41, the first drive block 621 and the second drive block 622 are movably arranged within the fixed shell 610, i.e., within the housing space. Specifically, the first drive block 621 is provided with an elongated first guide groove 621a into which the first guide column 10001a is inserted, and the first guide groove 621a and the first guide column 10001a cooperate to enable the first drive block 621 to reciprocate along the extending direction of the first guide groove 621a, i.e., the first direction D1 and the fifth direction D5. The second drive block 622 is provided with an elongated second guide groove 622a into which a second guide column 10001b is inserted, and the second guide groove 622a and the second guide column 10001b cooperate to enable the second drive block 622 to reciprocate along the extending direction of the second guide groove 622a, i.e., along the first direction D1 and the fifth direction D5. Of course, the first drive block 621 and the second drive block 622 may be movably arranged in the fixed shell 610 in other embodiments. The first direction D1 is opposite to the fifth direction D5.

[0135] Specifically, as shown in Figure 35, the first connecting seat housing 10002 is provided with a through hole 10002c that communicates with the housing space, and the first drive block 621 is movable along the fifth direction D5 so as to be exposed through the through hole 10002c, and the second drive block 622 is also movable along the fifth direction D5 so as to be exposed through the through hole 10002c. In this embodiment, there may be two through holes 10002c, into which the first drive block 621 and the second drive block 622 can be inserted, respectively. The orientation adjustment mechanism 600 further includes a separator 10001c. The separator 10001c is positioned between the first drive block 621 and the second drive block 622 and separates the first drive block 621 from the second drive block 622. In other embodiments, only one through-hole 10002c may be provided, provided that the first drive block 621 and the second drive block 622 can be inserted therein.

[0136] Furthermore, as shown in Figures 34 to 37, the first drive rib 631 and the second drive rib 632 are positioned on the handlebar 14, and the first connecting seat housing 10002 is provided with a track 10002d. The first drive rib 631 and the second drive rib 632 are movable along the track 10002d. Through the track 10002d, the first drive rib 631 can contact the first drive block 621, and the second drive rib 632 can contact the second drive block 622. Referring together to Figures 38 to 41, the first drive block 621 is positioned between the first drive rib 631 and the first directional mechanism 330, the handlebar 14 is rotated to the same side as the first travel assembly 300, and the first drive rib 631 pushes the first drive block 621 counterclockwise so that it moves toward the first direction D1, thereby locking the first directional mechanism 330. The second drive block 622 is positioned between the second drive rib 632 and the second directional mechanism 430, the handlebar 14 is rotated to the same side as the second travel assembly 400, and the second drive rib 632 pushes the second drive block 622 clockwise toward the first direction D1, thereby locking the second directional mechanism 430.

[0137] In this embodiment, both the first drive rib 631 and the second drive rib 632 are arc-shaped ribs. The first drive rib 631 and the second drive rib 632 have different arc lengths. For example, the arc length of the first drive rib 631 is smaller than the arc length of the second drive rib 632, thereby preventing the movement of the second drive block 622 from being hindered by an excessive arc length when the first drive rib 631 pushes the first drive block 621.

[0138] Furthermore, as shown in Figures 38 to 45, the two ends of the first traction member 641 are connected to the first drive block 621 and the first directional mechanism 330, respectively. Specifically, the two ends of the first traction member 641 are connected to one end of the first drive block 621 near the first pivot point M and to one end of the first directional pin 331 near the first pivot point M. That is, the first traction member 641 extends in the direction from the first drive block 621 toward the first directional pin 331. As a result, when moving along the fifth direction D5, the first drive block 621 can move along the fourth direction D4 by driving the first directional pin 331 via the first traction member 641, thereby pulling the first directional pin 331 away from the first directional groove 332 and unlocking the first directional mechanism 330.

[0139] Similarly, the two ends of the second traction member 642 are connected to the second drive block 622 and the second directional mechanism 430, respectively. Specifically, the two ends of the second traction member 642 are connected to one end of the second drive block 622 near the first pivot point M and to one end of the second directional pin 431 near the first pivot point M. That is, the second traction member 642 extends in the direction from the second drive block 622 toward the second directional mechanism 430. As a result, when moving along the fifth direction D5, the second drive block 622 can move along the fourth direction D4 by driving the second directional pin 431 via the second traction member 642, thereby pulling the second directional pin 431 away from the second directional groove 432 and unlocking the second directional mechanism 430.

[0140] In this embodiment, both the first traction member 641 and the second traction member 642 are made of steel wire. Of course, in other embodiments, the first traction member 641 and the second traction member 642 may be made of other materials.

[0141] Furthermore, as shown in Figures 38 to 41, the two ends of the first reset member 651 are in contact with the fixed shell 610 and the first drive block 621, respectively. Specifically, the first reset member 651 is positioned substantially along the first direction D1, one end of the first reset member 651 is positioned at the aforementioned end of the first drive block 621 near the first pivot point M, and the other end of the first reset member 651 is in contact with the fixed shell 610. The first reset member 651 constantly drives the first drive block 621 to move in the direction that unlocks the first directional mechanism 330. That is, the first reset member 651 constantly drives the first drive block 621 to move toward the fifth direction D5. As a result, when the handlebar 14 is rotated from the same side as the first travel assembly 300 to the same side as the second travel assembly 400, the first drive rib 631 switches from pressing against the first drive block 621 to not pressing against the first drive block 621. The first drive block 621 becomes movable along the fifth direction D5 under the elastic force of the first reset member 651, and the first directional pin 331 is driven to move toward the fourth direction D4 via the first traction member 641 and be pulled away from the first directional groove 332, thereby unlocking the first directional mechanism 330. The first reset member 651 may be a spring, an elastic rubber column, or the like.

[0142] Similarly, as shown in Figures 38 to 41, the two ends of the second reset member 652 are in contact with the fixed shell 610 and the second drive block 622, respectively. Specifically, the second reset member 652 is positioned substantially along the first direction D1, one end of the second reset member 652 is positioned at the aforementioned end of the second drive block 622 near the first pivot point M, and the other end of the second reset member 652 is in contact with the fixed shell 610. The second reset member 652 constantly drives the second drive block 622 to move in the direction that unlocks the second directional mechanism 430. That is, the second reset member 652 constantly drives the second drive block 622 to move toward the fifth direction D5. As a result, when the handlebar 14 is rotated from the same side as the second travel assembly 400 to the same side as the first travel assembly 300, the second drive rib 632 switches from pressing against the second drive block 622 to not pressing against the second drive block 622. The second drive block 622 becomes movable along the fifth direction D5 under the elastic force of the second reset member 652, and the second directional pin 431 is driven to move toward the fourth direction D4 via the second traction member 642, and away from the second directional groove 432, thereby unlocking the second directional mechanism 430. The second reset member 652 may be a spring, an elastic rubber column, or the like.

[0143] Furthermore, as shown in Figures 44 and 45, the two ends of the third reset member 653 are in contact with the second support member 102 and the first directional pin 331, respectively. The third reset member 653 ensures that the first directional mechanism 330 is always driven and locked. That is, the third reset member 653 always drives the first directional pin 331 to move toward the first directional groove 332. The elastic modulus of the third reset member 653 is smaller than that of the first reset member 651. This allows the first drive block 621 to overcome the elastic force of the third reset member 653 when the first drive rib 631 is not pressing against the first drive block 621, and to move along the fifth direction D5 under the elastic force of the first reset member 651, thereby unlocking the first directional mechanism 330. When the first drive rib 631 pushes the first drive block 621, the first drive block 621 moves along the fifth direction D5. When the first reset member 651 is compressed, the first directional pin 331 moves into the first directional groove 332 under the elastic force of the third reset member 653, thereby locking the first directional mechanism 330. The third reset member 653 may be a spring, an elastic rubber column, or the like.

[0144] Similarly, as shown in Figures 42 and 43, the two ends of the fourth reset member 654 abut against the first support member 100 and the second directional pin 431, respectively. The fourth reset member 654 ensures that the second directional mechanism 430 is always driven and locked. That is, the fourth reset member 654 always drives the second directional pin 431 to move toward the second directional groove 432. The elastic modulus of the fourth reset member 654 is smaller than that of the second reset member 652. This allows the second drive block 622 to overcome the elastic force of the fourth reset member 654 when the second drive rib 632 is not pressing against it, and to move along the fifth direction D5 under the elastic force of the second reset member 652, thereby unlocking the second directional mechanism 430. When the second drive rib 632 pushes the second drive block 622, the second drive block 622 moves along the first direction D1. When the second reset member 652 is compressed, the second directional pin 431 moves into the second directional groove 432 under the elastic force of the fourth reset member 654, thereby locking the second directional mechanism 430. The fourth reset member 654 may be a spring, an elastic rubber column, or the like.

[0145] The specific operating principle of the direction adjustment mechanism 600 according to this embodiment is as follows.

[0146] As shown in Figures 38 and 39, when the handlebar 14 is rotated to the same side as the first travel assembly 300, the first drive rib 631 presses against the first drive block 621, thereby positioning the first drive block 621 closer to the first pivot point M (i.e., in a lower position). In this case, the first traction member 641 is loosened, and the first directional pin 331 is moved along the third direction D3 under the elastic force of the third reset member 653, thereby inserting the first directional pin 331 into the first directional groove 332 and locking the first directional mechanism 330. At the same time, the second drive block 622, which is not being pressed, is positioned away from the first pivot point M (i.e., in an upper position) under the elastic force of the second reset member 652. In this case, the second traction member 642 is tensioned, and the second directional pin 431 is pulled by the second traction member 642, overcoming the elastic force of the fourth reset member 654 and moving along the fourth direction D4, causing the second directional pin 431 to be pulled away from the second directional groove 432 and unlocking the second directional mechanism 430. The third direction D3 is the opposite direction to the fourth direction D4.

[0147] Similarly, as shown in Figures 40 and 41, when the handlebar 14 is rotated to the same side as the second travel assembly 400, the second drive rib 632 presses against the second drive block 622, so that the second drive block 622 is positioned closer to the first pivot point M (i.e., in a downward position). In this case, the second traction member 642 is loosened, and the second directional pin 431 is moved along the third direction D3 under the elastic force of the fourth reset member 654, thereby inserting the second directional pin 431 into the second directional groove 432 and locking the second directional mechanism 430. At the same time, the unpressed first drive block 621 is positioned away from the first pivot point M (i.e., in an upward position) under the elastic force of the first reset member 651. In this case, the first traction member 641 is tensioned, and the first directional pin 331 is pulled by the first traction member 641, overcoming the elastic force of the third reset member 653 and moving toward the fourth direction D4, the first directional pin 331 is pulled away from the first directional groove 332, and the first directional mechanism 330 is unlocked.

[0148] In another embodiment, as shown in Figures 46 to 49, the orientation adjustment mechanism 600 includes a fixed shell 610, a first drive block 621, a second drive block 622, a first drive rib 631, a second drive rib 632, a first traction member 641, a second traction member 642, a first reset member 651, a second reset member 652, a third reset member 653, and a fourth reset member 654. The structure of the orientation adjustment mechanism 600 in this embodiment is substantially the same as the structure of the orientation adjustment mechanism 600 in the embodiments corresponding to Figures 33 to 45, except for the following point.

[0149] Firstly, as shown in Figures 46 to 49, the first traction member 641 has one end connected to the first direction mechanism 330 (specifically, connected to the first direction pin 331) and the other end connected to the first drive block 621, bypassing the separator 10001c. In this way, the first direction pin 331, the first traction member 641, the first drive block 621, and the separator 10001c form a pulley-like structure, so that the direction of movement of the first direction pin 331 is opposite to the direction of movement of the first drive block 621. In this way, when moving along the first direction D1, the first drive block 621 drives the first direction pin 331 to move along the fourth direction D4, thereby unlocking the first direction mechanism 330.

[0150] Similarly, as shown in Figures 46 to 49, the second traction member 642 has one end connected to the second directional mechanism 430 (specifically, connected to the second directional pin 431) and the other end connected to the second drive block 622, bypassing the separator 10001c. In this way, the second directional pin 431, the second traction member 642, the second drive block 622, and the separator 10001c form a pulley-like structure, so that the direction of movement of the second directional pin 431 is opposite to the direction of movement of the second drive block 622. In this way, when moving along the first direction D1, the second drive block 622 drives the second directional pin 431 to move along the fourth direction D4, thereby unlocking the second directional mechanism 430.

[0151] Secondly, as shown in Figures 46 and 47, when the handlebar 14 is rotated to the same side as the first travel assembly 300, the second drive rib 632 pushes against the second drive block 622 along the first direction D1, so the second directional mechanism 430 becomes unlocked, and at the same time, the first drive block 621 is not pushed by the first drive rib 631, so the first directional mechanism 330 becomes locked. As shown in Figures 48 and 49, when the handlebar 14 is rotated to the same side as the second travel assembly 400, the first drive rib 631 pushes against the first drive block 621 along the first direction D1, so the first directional mechanism 330 becomes unlocked, and at the same time, the second drive block 622 is not pushed against by the second drive rib 632, so the second directional mechanism 430 becomes locked.

[0152] Furthermore, in this embodiment, as shown in Figures 46 to 49, since the direction of movement of the first directional pin 331 is opposite to the direction of movement of the first drive block 621, when the first drive rib 631 is not pushing against the first drive block 621, the first drive block 621 can move along the fifth direction D5 under the elastic force of the first reset member 651. In this case, as soon as the first traction member 641 is loosened, the first directional pin 331 moves along the third direction D3 under the elastic force of the third reset member 653, thereby locking the first directional mechanism 330. Therefore, in this embodiment, the elastic modulus of the third reset member 653 does not need to be smaller than the elastic modulus of the first reset member 651.

[0153] Similarly, as shown in Figures 46 to 49, in this embodiment, since the direction of movement of the second directional pin 431 is opposite to the direction of movement of the second drive block 622, the second drive block 622 can move along the fifth direction D5 under the elastic force of the second reset member 652 when the second drive rib 632 is not pushing against the second drive block 622. In this case, as the second traction member 642 is loosened, the second directional pin 431 moves along the third direction D3 under the elastic force of the fourth reset member 654, thereby locking the first directional mechanism 330. Therefore, in this embodiment, the elastic modulus of the fourth reset member 654 does not need to be smaller than the elastic modulus of the second reset member 652.

[0154] The specific operating principle of the direction adjustment mechanism 600 according to this embodiment is as follows.

[0155] As shown in Figures 46 and 47, when the handlebar 14 is rotated to the same side as the first travel assembly 300, the second drive rib 632 presses against the second drive block 622, causing the second drive block 622 to overcome the elastic force of the second reset member 652 and be positioned closer to the first pivot point M (i.e., in a lower position). At this time, the second traction member 642 is tensioned, and simultaneously the second traction member 642 pulls the second directional pin 431, causing it to overcome the elastic force of the fourth reset member 654 and move along the fourth direction D4, thereby pulling the second directional pin 431 away from the second directional groove 432 and unlocking the second directional mechanism 430. Simultaneously, the unpressed first drive block 621 is positioned away from the first pivot point M (i.e., in an upper position) under the elastic force of the first reset member 651. In this case, the first traction member 641 is loosened, and the first directional pin 331 moves along the third direction D3 under the elastic force of the third reset member 653, thereby inserting the first directional pin 331 into the first directional groove 332 and locking the first directional mechanism 330.

[0156] Similarly, as shown in Figures 48 and 49, when the handlebar 14 is rotated to the same side as the second travel assembly 400, the first drive rib 631 presses against the first drive block 621, causing the first drive block 621 to overcome the elastic force of the first reset member 651 and be positioned closer to the first pivot point M (i.e., in a lower position). At this time, the first traction member 641 is tensioned, and simultaneously the first traction member 641 pulls the first directional pin 331, causing it to overcome the elastic force of the third reset member 653 and move along the fourth direction D4, thereby pulling the first directional pin 331 away from the first directional groove 332 and unlocking the first directional mechanism 330. Simultaneously, the unpressed second drive block 622, under the elastic force of the second reset member 652, is positioned further away from the first pivot point M (i.e., in an upper position). In this case, the second traction member 642 is loosened, and the second directional pin 431 moves along the third direction D3 under the elastic force of the fourth reset member 654, thereby inserting the second directional pin 431 into the second directional groove 432 and locking the second directional mechanism 430.

[0157] In yet another embodiment, for example, in the embodiment corresponding to Figures 46 to 49, with reference to Figures 50 to 56, the direction adjustment mechanism 600 further includes a third drive member 660 and a fifth reset member 655. The third drive member 660 has a substantially annular structure. The third drive member 660 has a first drive rib 631 and a second drive rib 632 arranged in an annular manner. The third drive member 660 is pivotably connected to the handlebar 14. The first drive rib 631 and the second drive rib 632 are movable on the track 10002d. The first drive rib 631 can abut against the first drive block 621, and the second drive rib 632 can abut against the second drive block 622. When the handlebar 14 is reversed, the third drive member 660 is fixed to the handlebar 14. The two ends of the fifth reset member 655 abut against the third drive member 660 and the handlebar 14, respectively, and the fifth reset member 655 keeps the third drive member 660 fixed to the handlebar 14 at all times. The fifth reset member 655 may be a spring, an elastic rubber column, or the like.

[0158] Specifically, as shown in Figures 50 to 54, the drift drive mechanism 700 includes a third traction member 710 and a drift operating member 720. The two ends of the third traction member 710 are connected to the drift operating member 720 and the third drive member 660, respectively. In this embodiment, the third traction member 710 is a steel wire. Of course, in other embodiments, the third traction member 710 may be made of other materials. The drift operating member 720 is operable via the third traction member 710 to drive the third drive member 660 so that it can rotate relative to the handlebar 14, overcoming the force of the fifth reset member 655, until the first drive rib 631 and the second drive rib 632 simultaneously press against the first drive block 621 and the second drive block 622, respectively. In this way, both the first drive block 621 and the second drive block 622 are positioned close to the first pivot point M (i.e., in a downward position). In this case, both the first traction member 641 and the second traction member 642 are tensioned. Simultaneously, the first traction member 641 pulls the first directional pin 331, overcoming the elastic force of the third reset member 653 and causing it to move along the fourth direction D4, and the second traction member 642 pulls the second directional pin 431, overcoming the elastic force of the fourth reset member 654 and causing it to move along the fourth direction D4, thereby unlocking both the first directional mechanism 330 and the second directional mechanism 430. As a result, the passenger device can achieve a drift function.

[0159] In further embodiments, such as those corresponding to Figures 33 to 45, a drift drive mechanism 700 and a fifth reset member 655 may also be added. The user operates the drift operating member 720 to rotate the third drive member 660 relative to the handlebar 14, overcoming the force of the fifth reset member 655 until the first drive rib 631 and the second drive rib 632 no longer press against the first drive block 621 and the second drive block 622. In this way, both the first drive block 621 and the second drive block 622 are positioned away from the first pivot point M (i.e., in an upward position). In this case, the first traction member 641 and the second traction member 642 are tensioned upward, thereby unlocking both the first directional mechanism 330 and the second directional mechanism 430. As a result, the passenger device can achieve a drift function.

[0160] The above-described passenger device has at least the following technical effects.

[0161] The handlebar 14 is rotatable relative to either the first travel assembly 300 or the second travel assembly 400 to achieve a reversal function. When the handlebar 14 is rotated to the same side as the first travel assembly 300, the orientation of the first wheel member 320 and the deorientation of the second wheel member 419 can be achieved through the orientation adjustment mechanism 600. When the handlebar 14 is rotated to the same side as the second travel assembly 400, the orientation of the second wheel member 419 and the deorientation of the first wheel member 320 can be achieved through the orientation adjustment mechanism 600. That is, during the reversal of the handlebar 14, the orientation adjustment function can be achieved by the orientation adjustment mechanism 600 between the first travel assembly 300, the second travel assembly 400, and the handlebar 14, thereby facilitating the pushing of the passenger device after reversal. The orientation function of the orientation adjustment mechanism 600 is mainly achieved through the first drive block 621 and the second drive block 622, which have a simple structure and are easy to implement. The above-described passenger device can implement the function of adjusting the direction of the wheels while reversing the handlebar 14 with a simple structure, thereby reducing the manufacturing cost of the above-described passenger device.
