5. The assembling method according to claim 4, characterized in that: The step A1 also includes the step of assembling the wheel set (2); B1: Install the first mounting plate (32) on one side and the opposite side of the motor shaft of the driving motor (31), then snap-connect two second mounting plates (34) between the first mounting plates (32), and finally snap-connect a plurality of clamping plates (33) on the top and bottom of the first mounting plate (32) to form a motor housing that wraps the driving motor (31), and the motor shaft of the driving motor (31) passes through the first mounting plate (32) and extends out of the motor housing; B2: Two motor housings enclosing drive motors (31) are arranged in a mirror-image manner with the motor shafts facing outwards, and then an end plate (221) and a clamping plate (33) are snap-connected from either the top or bottom end of the drive motor (31), and then a side plate (222) is snap-connected with the end plate (221) from both sides close to the motor housing on one side of the motor shaft, and the motor shaft is extended out of the side plate (222), and then another end plate (221) is snap-connected with the clamping plate (33) and the side plate (222) from the other end of the drive motor (31), thereby forming a box (22) enclosing the power mechanism (3); B3: A plurality of second connecting plates (5) are provided on a side of the side plate (222) opposite to the extension section (2221), which are inserted into the first clamping holes (2211) of the two end plates (221), and the two end plates (221) are clamped and fixed. Then, a connecting fixing plate (6) is clamped on the top or bottom of the second connecting plate (5), and the plurality of second connecting plates (5) are connected and fixed. The end plates (221) are further clamped and fixed. Finally, a wheel (21) is inserted into the motor shaft extending out of the side plate (222) to form the wheel set (2).

6. The assembling method according to claim 5, characterized in that: The step A3 also includes the step of locking the wheel set (2) and the assembled frame (1): C1: snap-connect the extension section (2221) of the side panel (222) to the top panel (13) and the bottom panel (14) respectively; C2: snap-connecting the first locking plate (41) of the locking portion (4) to the extension section (2221) from the top of the top plate (13) and the top of the bottom plate (14); C3: The second locking plate (42) of the locking portion (4) is inserted from both sides of the assembled frame (1) and connected with the top plate (13), the bottom plate (14) and the first locking plate (41) respectively by snapping.
