Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1 to 6, a battery pack protective frame, includes frame 1, the parallel is equipped with a plurality of parting beads 2 in frame 1, the equal symmetry in both ends of parting bead 2 is equipped with two sets of buffering subassemblies, parting bead 2 is through buffering subassembly and frame 1 inner wall connection, the bottom bilateral symmetry of frame 1 is equipped with slide rail 13, sliding connection has a plurality of draw runner 14 in slide rail 13, be equipped with installing frame 5 on the draw runner 14, installing frame 5 and draw runner 14 are located between two adjacent parting beads 2, be equipped with battery module 9 on installing frame 5, when battery module 9 does not receive the impact, buffering subassembly is spacing with parting bead 2, when battery module 9 receives external force to strike, buffering subassembly buffering energy-absorbing and make parting bead 2 and frame 1 relative slip. The end plate of the outer frame 1 may be arranged to be slidably connected to the slide rails 13 and also to slide along the slide rails 13 in case of impact.

In this embodiment, buffer unit includes spring 41 and trapezoidal piece 4, all be equipped with two spouts 3 and a square groove 12 on the both sides inner wall of frame 1, the upper and lower of square groove 12 is located to two spout 3 symmetries, the outside sliding connection of trapezoidal piece 4 is in square groove 12, spring 41 is located between square groove 12 and the trapezoidal piece 4, the both ends of parting bead 2 are symmetrical wedge, the inboard inclined plane of trapezoidal piece 4 and the tip inclined plane sliding connection of parting bead 2, sliding connection has slider 21 in the spout 3, the tip outside of parting bead 2 is located to slider 21.
