[0046] In one embodiment, the handle 331 is movably pivoted to the front surface of the battery 33 .

[0047] In one embodiment, a waterproof rubber strip is disposed on the front surface of the battery box 31 and at the periphery of the openings of the plurality of accommodating grooves 311 .

[0048] Accordingly, when the waterproof cover 312 closes the receiving groove 311 and locks the battery 33 , it has the functions of sealing, waterproofing and dustproofing.

[0049] The above is an introduction to the components and their composition of the utility model. Next, the use characteristics and effects of the utility model are introduced as follows:

[0050] like Figure 3 , Figure 4 , Figure 5 As shown, the disassembly procedure of the motor wheel assembly 20 is:

[0051] First, remove the screws 23 , then remove the side cover 12 , then pull out the quick-release transmission connector 22 and separate it from the transmission line 13 , and finally pull out the motor wheel assembly 20 .

[0052] like Figure 7 , Figure 8 , Fig. 9 As shown, the extraction procedure of the battery 33 is:

[0053] First, open the fixing member 313 on the battery box 31 , then open the waterproof cover 312 , and then pull the handle 331 upwards. By pulling the handle 331 , the battery 33 can be easily pulled out of the receiving slot 311 .

[0054] The utility model uses the same structure for each support frame 11, which is beneficial to sharing one mold for production, saving mold opening costs and reducing manufacturing costs.

[0055] The utility model integrates the driver 321 and the battery box 31 in the battery module, and enables the battery 33 to be replaceable.
