[0029] The movement of the first linkage assembly 73 is as follows: The first positioning post on the first sliding rail 32 and the second positioning post on the first positioning plate 3202 drive the first connecting rod 7301 and the second connecting rod to move, which in turn drive the third connecting rod to move under the restriction of the fourth connecting rod 7305. The third connecting rod 7303 drives the first synchronization rod 7304 to move. The movement of the second linkage assembly 74 is as follows: The third positioning post on the second sliding rail 34 and the fourth positioning post on the second positioning plate 3402 drive the fifth connecting rod 7401 and the sixth connecting rod to move, and drive the fifth connecting rod to move under the limitation of the eighth connecting rod 7405, and the fifth connecting rod 7401 drives the second synchronization rod 7404 to move.

[0032] The front pedal 1 can also be foldably provided with a telescopic riser.

[0033] The control method of the electric scooter is characterized by comprising the following steps: detecting the remaining power of the first battery pack 4 and the second battery pack 5 in real time; When the pedals are detected to be engaged and no long-distance mileage is preset, the single-battery priority power supply mode is activated: only the main battery pack is used for power supply until its power level is ≤20%, and then it automatically switches to the backup battery pack; When the user sets the target mileage to > 15km or manually activates the parallel command, the dual battery parallel mode is started; The dynamic selection of a high-health battery pack as the main power supply unit; The backup battery pack remains in a dormant state until the main battery pack triggers the switching threshold; During the pedal separation process, the first magnetic contact piece 61 and the second magnetic contact piece 62 are disconnected, and the baffle 71 is driven to cover the magnetic contact pieces.

[0034] The control method of the electric scooter and the electric scooter work as follows: When folding is required in the initial state: The lock between the connecting rod pull buckle and the first locking buckle is released. By pulling the front pedal 1 and the rear pedal 2 to the sides at the same time, the two pedals synchronously drive the first sliding rail 32 and the second sliding rail 34, thereby separating the front pedal 1 and the rear pedal 2. Subsequently, the front pedal 1 and the rear pedal 2 are folded together by the cooperation between the first positioning frame 3201, the second positioning frame 3401 and the rotating block 35. The movement between the first sliding rail 32 and the second sliding rail 34 also synchronously drives the first linkage assembly 73 and the second linkage assembly 74, thereby driving the baffle 71 to move. When the baffle 71 moves, the driving block 7101 thereon gradually drives the guide rod 6302 and the connecting block 6301 to move, and squeezes the spring 64. The connecting block 6301 also drives the magnetic contact piece to move, so that the magnetic contact piece moves into the installation compartment 63, thereby not affecting the closure of the baffle 71.
