【Detailed ways】

Below in conjunction with accompanying drawing, the utility model embodiment is described in detail.

Embodiment 1: As shown in Figures 1 and 2, the lock frame of the electric vehicle battery is made of iron bars, the outer layer is galvanized, and the thickness of each iron bar is 2MM. Four concave iron bars 2 are welded between the lower iron bars 3 and 4 parallel to each other to form the lower iron frame 9, and an iron sheet is welded on the outside of the middle part of the iron bar 3, and the iron sheet has a lower keyhole 8; the upper iron bar 6 is upward Protrusion, which is connected to the outer middle part of the iron bar 4 through a rotating shaft 5, the other end of the upper iron bar 6 is bent, and the bending part is provided with an upper lock hole 7, and the upper and lower lock holes 7 and 8 correspond to each other. Pass through the lock holes 7, 8 to lock the lock frame of the present utility model. The lock frame of this embodiment is suitable for locking the storage battery placed on the front inclined bracket of the electric vehicle. Integrate with the frame.

Embodiment two: as shown in Figure 3, metal strip adopts stainless steel, and outer layer spray paints, and the thickness of each stainless steel strip is 3MM; Three stainless steel strips 2 are welded between stainless steel strip 3,4 and constitute lower frame 9, the length of lower frame 9 The width ratio is different from that of Embodiment 1. This embodiment is applicable to the locking when the storage battery is placed on the pedal of the electric vehicle, and other structures are the same as the first embodiment.

Embodiment three: as shown in Figure 4, metal bar adopts iron bar, outer layer is sprayed with plastic, and the thickness of each iron bar is 2.5MM; Weld four iron bars 2 between mutually parallel iron bars 3,4 and form lower frame 9. The length-to-width ratio of the lower frame 9 is different from that of the second embodiment to meet the needs of different electric vehicle models, and the other structures are the same as those of the second embodiment.
