Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

As shown in fig. 1 to 5, a power battery box includes an outer box 1, an upper cover 2 and power batteries 3, the outer box 1 is connected with the upper cover 2 by screws, a plurality of sets of power batteries 3 are arranged in the outer box 1, a bottom plate 16 is arranged at the bottom end of the outer box 1, a plurality of structurally symmetrical abdicating grooves 4 are formed in the bottom plate 16, limiting assemblies 5 are arranged in the abdicating grooves 4, and every two limiting assemblies 5 limit a set of power batteries 3.

Spacing subassembly 5 is including installing in the two 12 locating pieces of 6 locating pieces and two structural symmetries of the inslot of stepping down 4, sliding connection guide pillar 7 in the two 12 locating pieces, limiting plate 8 is connected to guide pillar 7 one end, and wedge 9 is connected to the other end, 7 overcoat of guide pillar connects spring one 10, two 12 locating pieces and wedge 9 are connected respectively to spring one 10 both ends, two wedge 9 between be equipped with two 17 wedges, two sides and the side sliding fit of two wedge 9 of two 17 wedges, two 17 lower extremes of wedge are equipped with sliding connection in the guide arm 11 of locating piece one 6, 11 overcoat connects spring two 13 of guide arm, one 6 locating pieces and 1 diapire of outer container are connected respectively to two 13 both ends of spring.

The outer box body 1 is provided with a plurality of heat dissipation holes 14, which is beneficial to ventilation and heat dissipation in the outer box body 1.

A gasket 15 is arranged between the outer box body 1 and the upper cover body 2.

The working process and principle are as follows: when the power battery box is actually used, when the power battery 3 is placed into the outer box body 1, the power battery 3 presses the second wedge block 17 by self gravity, the second wedge block 17 and the guide rod 11 move downwards, at the moment, the second spring 13 is compressed, and as the two side faces of the second wedge block 17 are in sliding fit with the side faces of the first wedge blocks 9, the first wedge blocks 9 slide along opposite directions, so that the guide pillar 7 drives the limiting plate 8 to move, at the moment, the first spring 10 is compressed, and after the power battery 3 is completely placed, the limiting plates 8 on the two sides can just clamp the two sides of the power battery 3, so that the battery box is prevented from shaking in the carrying process, the power batteries 3 collide with each other, and the service life is influenced.
