Cellular sandwich 2 corresponds, and the trapezoidal shape of the trapezoidal corrugated plating 4 is located at the surface of corresponding cellular sandwich 2, plays suction
The effect of energy, vibration damping and heat dissipation.Label 6 in Fig. 2 indicates through-flow space.
The trapezoidal corrugated plating 4 uses aluminium alloy, and batteries of electric automobile packet is improved using aluminium alloy ripple sandwich
Bottom crash-worthiness has certain versatility, sandwich directly can be fixed on electric car using bolt or viscose glue etc.
The bottom of battery pack 5, it is flexible and convenient to use.
The utility model is applied in the protection of battery of electric vehicle packet, for improving the crash-worthiness of batteries of electric automobile packet bottom
Deng.Specific installation process are as follows: be sequentially connected regular hexagon cellular sandwich；By regular hexagon cellular sandwich be connected to top plate and
Between lower plywood；It is fixed on top plate using trapezoidal corrugated plating；Trapezoidal corrugated plating is fixed on by modes such as bolt, viscose glues
The bottom of batteries of electric automobile packet.
Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
These are merely examples, and the protection scope of the utility model is defined by the appended claims.Those skilled in the art
Member can make numerous variations or be repaired to these embodiments under the premise of without departing substantially from the principles of the present invention and essence
