Example 1

Referring to fig. 1, a battery protection box for a new energy automobile includes a cover plate 11, wherein an actuation assembly for driving air to flow and an electric control assembly for managing and controlling the operation of the battery are provided on the cover plate 11.

Referring to fig. 2 and 3, the new energy automobile battery protection box in the present embodiment further includes a main frame, and a cover plate 11 is hermetically covered on the main frame; the total frame includes a plurality of holding frame 13, and a plurality of holding frame 13 are arranged in proper order along car straight line advancing direction, and adjacent two are held frame 13 and are connected through the beam 14 that collapses, and the mechanical strength that collapses the beam 14 is less than holding frame 13 for total frame is earlier than holding frame 13 and takes place deformation when receiving external force extrusion that collapses the beam 14.

Preferably, the number of crush beams 14 in the same flow channel 16 is two and located at each end of the flow channel 16.

Preferably, crush beam 14 has a buckle structure.

When the main frame is extruded and deformed by external force, the bent crumple beams 14 are extruded and bent, and the process can absorb the energy extruded by the external force to generate an energy absorption effect; the flow channel 16 is capable of providing a displacement distance to the containment frame 13, which is advantageous and reduces the probability of deformation of the containment frame 13 when the overall frame is deformed under the influence of an external force.
