Connect.Advantage：Detachable connection structure can be suitably used on any vehicle frame, its simple structure, easy to loading and unloading, low production cost.
To the further restriction of above-mentioned technical proposal, the radiator is arranged on bottom half.Advantage：Radiator is accelerated
The radiating rate of casing.
Beneficial effect：Touched by the structure energy absorption and buffering of arch anticollision pilot beam itself when there is side collision
Power is hit, the impact force of reduction is evenly distributed on battery case, it is to avoid battery case causes excessive extruding because of discontinuity
Deng failure mode, prevent because battery case destruction and caused by cell electrical danger situation；The present invention is ensureing battery case connection
In the case of simple installation, intensity, rigidity and heat-sinking capability, when crashing, battery case collision safety had both been ensure that
Property, it is to avoid there is the electrical safety accident that battery case is damaged and caused, decrease the cost for changing battery case.

Specific embodiment
Specific embodiment of the invention is described further with reference to this example figure, so as to the technology of the present invention side
Case should be readily appreciated that and grasp.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of battery of electric vehicle box structure of anticollision buffering, including casing 1 and case lid
2, two arch anticollision pilot beams 3 of parallel connection are equipped with the rear and front end face of casing 1, arch anticollision pilot beam 3 is connected by bolt
The mode for connecing is fixed on casing 1；Eight and half suspension type connecting plates 4, i.e. each side of casing are provided with the left and right sides of casing 1 altogether
There are one and half suspension type connecting plates 4 at four angles in face；The inner of half suspension type connecting plate is connected by bolt assembly with casing
Connect, the overhanging end of half suspension type connecting plate is provided with connecting hole and is connected with vehicle frame by bolt；The two of half suspension type connecting plate
End is removable attachment structure, is so easy to adjust the position of connecting plate overhanging end, can be applied on any vehicle frame, dress
Unload, adjust more convenient；Radiator 5 is bonded on the bottom surface of the base plate of casing 1, and radiator 5 is by multiple on box bottom
Fin constitute, be set in distance between fin, spaced fin increases the area with air contact,
So as to accelerate radiating rate；The vapor chamber 6 of bonding is equipped with the back side of case lid 2, the bottom of the inner chamber of casing 1 and inwall,
The rectangular array of vapor chamber 6 is distributed；The back side of case lid 2 is provided with the groove of annular, and sealing joint strip 7, case are provided with groove
