They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present application.

[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, "multiple" means two or more, and "several" means one or more, unless otherwise clearly and specifically defined.

[0029] Reference Figures 1 to 3 A foldable scooter provided in an embodiment of the present application includes a chassis 10, a front wheel 11 and a rear wheel 12 disposed on the chassis 10, a handlebar assembly 20 disposed on the chassis 10, and a seat assembly 30 disposed on the chassis 10. The handlebar assembly 20 includes a lower shell assembly 22, an upper shell assembly 21 disposed on the lower shell assembly 22 and rotatably connected to the lower shell assembly 22, a locking structure 40 disposed between the upper shell assembly 21 and the lower shell assembly 22 for locking or unlocking the two, and a control system (not shown in the figure) disposed in the upper shell assembly 21 and the lower shell assembly 22. When folding is required, the locking structure 40 is unlocked, the upper shell assembly 21 and the lower shell assembly 22 can be rotated and folded, the upper shell assembly 21 is bent downward and folded to one side of the lower shell assembly 22, and when unfolded, the upper shell assembly 21 is rotated to the top of the lower shell assembly 22 and locked by the locking structure 40.

[0030] Specifically, the locking structure 40 includes a latch 41 disposed on the lower shell assembly 22 and extending into the upper shell assembly 21, and a rotary lock core 42 disposed on the upper shell assembly 21. The rotary lock core 42 includes a rotating shaft 43, a knob 44 disposed at one end of the rotating shaft 43, and a lock tongue 45 threadedly connected to the other end of the rotating shaft 43 and capable of moving forward and backward as the rotating shaft 43 rotates. When the lock core is operated, the rotating shaft 43 rotates by rotating the knob 44. Since the lock tongue 45 is threadedly connected to the rotating shaft 43 and the rotating shaft 43 is fixed in the axial direction, when the rotating shaft 43 rotates, the thread on it drives the lock tongue 45 to move forward and backward along the rotating shaft 43. The locking structure 40 also includes a locking confirmation safety structure, which includes a micro switch 47 arranged on the inner side of the lock tongue 45, the micro switch 47 is connected to the control system, the lock tongue 45 is unlocked or locked with the latch 41 when moving forward or backward, and the lock tongue 45 and the latch 41 trigger the opening of the micro switch 47 when locking. In this way, when the handlebar assembly 20 is unfolded from the folded state, if the upper shell assembly 21 and the lower shell assembly 22 are not locked in place after being unfolded, the micro switch 47 is in a closed state, the control system is not connected, and the scooter cannot be turned on and used, reminding the user to continue to rotate the knob 44 until the locking structure 40 is completely locked. In this way, adding the locking confirmation safety structure fundamentally avoids the upper shell assembly 21 and the lower shell assembly 22 being not locked and starting to ride, and avoids the upper shell assembly 21 and the lower shell assembly 22 being folded due to not being locked during riding, thereby greatly improving the safety performance of the scooter.

[0031] Further, refer to Figure 4 , Figure 5 The rotary lock core 42 further includes an elastic member 46 disposed at one end of the rotating shaft 43 and located between the knob 44 and the lock tongue 45. Specifically, the elastic member 46 is a spring. When the lock tongue 45 is inserted into the latch 41, the spring is compressed, and the elastic restoring force of the spring is used to push against the lock tongue 45 so that the lock tongue 45 and the latch 41 are inserted more tightly, that is, the locking between the upper shell assembly 21 and the lower shell assembly 22 is more stable.

[0032] Specifically, in this embodiment, the lock tongue 45 includes a body 451 located in the middle, a connector 452 disposed at the top of the body 451, and a lock hook 453 located at the bottom of the body 451 and bent toward the latch 41. The connector 452 has a connection hole 4521, and the connection hole 4521 has a thread. The other end of the rotating shaft 43 is inserted into the connection hole 4521, that is, the lock tongue 45 is threadedly connected to the rotating shaft 43 through the connector 452. At the same time, the latch 41 is provided with a locking hole 454, and when the lock tongue 45 moves forward and backward, the lock hook 453 is buckled or disengaged from the locking hole 454. The micro switch 47 is located inside the body, and when the lock tongue 45 moves forward and backward, the body located in the middle is used to release the micro switch 47, or press the micro switch 47.

[0033] Furthermore, two guide holes 455 are symmetrically provided at both ends of the body of the lock tongue 45, and two guide posts 48 are horizontally provided in the upper shell assembly 21 along the front-to-back direction, and the two guide posts 48 are respectively inserted into the two guide holes 455. That is, the lock tongue 45 is guided by the two guide posts 48 during the movement process to avoid left or right deviation during the movement process.

[0034] In this embodiment, in order to make the upper shell component 21 and the lower shell component 22 more labor-saving when folding or unfolding, a reset structure is also provided between the two. The reset structure includes a first mounting hole (not numbered in the figure) longitudinally provided on the upper shell component 21, a second mounting hole (not numbered in the figure) longitudinally provided on the lower shell component 22 and corresponding to the first mounting hole, and a reset spring 50, the upper end of the reset spring 50 is located in the first mounting hole, and the lower end of the reset spring 50 is located in the second mounting hole. In the unfolded state, the reset spring 50 is vertically provided and penetrates the upper shell component 21 and the lower shell component 22 at the same time; in the folded state, the reset spring is driven by the upper shell component 21 to be bent.

[0035] Further, the seat assembly 30 includes a seat cushion 31 and a folding bracket 32 ​​supporting the seat cushion 31, and a distance sensor element (not shown in the figure) for sensing the height of the seat cushion 31 is provided on the chassis 10. The seat cushion 31 can be further folded by using the folding bracket 32, which saves space and is convenient for storage or transportation of the scooter when not in use. The folding bracket 32 ​​can be folded in a "Z" shape, and the folding bracket 32 ​​is a prior art and will not be described here. The folding bracket 32 ​​also has a locking structure after unfolding. In order to avoid not being locked in place after unfolding, the above-mentioned distance sensor element is provided on the chassis 10, and the distance sensor element is connected to the control system. The height of the seat cushion 31 after unfolding is sensed and measured by the distance sensor element. When the height is equal to the preset height, it means that the seat cushion 31 is unfolded in place and locked. At this time, the control system can be started and operated normally. When the unfolded height of the seat cushion 31 sensed and measured by the distance sensor element is less than the preset height, it means that the seat cushion 31 is not unfolded in place and is in an unlocked state. At this time, the control system cannot be started normally. Alternatively, the distance sensor element may be connected to an alarm. When the seat cushion 31 is not deployed and not locked, the alarm is sounded to remind the user to adjust the seat cushion 31 height until the requirement is reached.

[0036] In summary, in the present application, for the folding scooter, a micro switch 47 is provided on the folding handlebar assembly 20 and is connected to the control system. Whether the locking structure 40 is locked in place is checked by whether the micro switch 47 is triggered, which greatly improves the safety performance of the scooter and allows users to use it with more confidence and safety.

[0037] The above description is only a specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
