the Hall sensor is used for sensing a magnetic field between the second detection piece and the Hall sensor and sending a detection signal determined by the Hall sensor to the controller;
the optical sensor is used for detecting whether the second detection piece is within a first preset distance or not and sending a detection signal determined by the optical sensor to the controller;
the laser distance sensor is used for detecting the distance between the second detection piece and the laser distance sensor and sending a detection signal determined by the laser distance sensor to the controller.
5. The folding mechanism of claim 1, further comprising:
and the vertical pipe is used for being butted and locked with the locking spanner.
6. A folding mechanism as claimed in claim 5, wherein said first sensing member is disposed in at least one of: the base portion, the fold portion, the riser.
7. The folding mechanism of claim 3 wherein said controller is further configured to determine that said locking wrench is not in said locked position if said detection signal is greater than a first predetermined threshold; and determining that the locking wrench is in the locking position if the detection signal is less than a second preset threshold.
8. The folding mechanism of claim 7, wherein: the first detecting member includes: the Hall sensor is further used for determining that the detection signal is greater than the first preset threshold value under the condition that the magnetic field between the second detection piece and the Hall sensor is smaller than a third preset threshold value; and determining that the detection signal is smaller than a second preset threshold value when the magnetic field between the second detection piece and the Hall sensor is larger than a fourth preset threshold value.
9. The folding mechanism of claim 1, wherein: the folding mechanism further comprises: a motor, the controller coupled to the motor, wherein,
the controller is further configured to control the motor to execute a first operating event if it is determined that the locking wrench is not in the locked position, wherein the first operating event is configured to disable the foldable ride-on vehicle.
10. The folding mechanism of claim 9, wherein: the controller is further configured to perform at least one of:
instructing the controller to inhibit operation of the motor if it is determined that the locking wrench is not in the locked position;
instructing the controller to control the motor to idle in a case where it is determined that the locking wrench is not in the locking position;
instructing the controller to control the motor to abnormally rotate in a case where it is determined that the lock wrench is not in the lock position.
11. The folding mechanism of claim 1, wherein: the folding mechanism further comprises: a multimedia device, the controller coupled to the multimedia device, wherein,
the controller is used for controlling the multimedia device to execute a second operation event under the condition that the locking wrench is determined not to be in the locking position, wherein the second operation event is used for reminding a target object of forbidding the folding mechanism to operate.
12. The folding mechanism of claim 11, wherein: the multimedia device includes: the controller is further used for instructing the sounding device to give a warning sound when the locking wrench is determined not to be in the locking position.
13. The folding mechanism of claim 11, wherein: the multimedia device includes: a light emitting device, the controller further configured to instruct the light emitting device to display a warning lamp if it is determined that the locking wrench is not in the locked position.
14. The folding mechanism of claim 11, wherein: the multimedia device includes: a display device, the controller further configured to instruct the display device to display an alarm signal if it is determined that the locking wrench is not in the locking position.
