Embodiment 1

[0041] Embodiment one, refer to Figure 1-4 , Figure 6-8, discloses a battery box installation locking device, the device mainly includes two parts, the installation plate 1 installed on the electric bicycle, the installation plate 1 includes a locking part 11 and a positioning part 12, the locking part 11 is provided with a number of fixed slots 10 for mutual fixation with the electric bicycle body, the locking part 11 is also provided with a first lock hole 111, and the positioning part 12 is provided with a number of positioning plates 13 for installation. When installing the battery box 3, after fixing the mounting plate 1 to the electric bicycle body, the positioning plate 13 is fitted to the positioning part 12 after the bolts and the insert nuts 132 at the bottom of the positioning boss 131 are fitted together. Above, fix the positioning plate 13 on the electric bicycle body through the fixed through groove 10 on the positioning plate 13, so as to make the mounting pl...

Embodiment 2

[0042] Embodiment two, refer to Figure 1-3 , Figure 5-6 , in the design of the positioning plate, the outer edge of the positioning plate 13 can be used to set the positioning retaining edge 102 to fix the bottom of the battery box 3. This design method can meet the design needs of different electric bicycle structures and battery boxes. The installation of the positioning groove at the bottom of the battery box is reduced.

Embodiment 3

[0043] Embodiment three, refer to Figure 1-3 , the interaction between the second lock hole set on the handle and the lock bar, the elastic lock tongue can also be selected, and the elastic lock tongue is set in the cavity where the extension block rotates. When the handle is fastened to the top of the battery box, the extension block Push the elastic lock tongue. When the extension block is in a vertical state, push the elastic lock tongue to spring into the second lock hole to form a locking effect. This method can meet the different design effects of the battery box lock lever and shape.
