Description
Technical Field
The utility model relates to the technical field of lower protection plates of new energy automobile battery packs, in particular to a honeycomb sandwich protection plate.
Background
The lower protection plate of the new energy automobile is mainly used for protecting the battery pack and the lower box body of the battery pack and preventing the battery pack and the lower box body of the battery pack from being broken down by hard substances to cause leakage of oil of the battery pack or damage of the lower box body and the like. At present, a lower protection plate is rarely installed on a new energy automobile battery pack. At present, plastic plates are basically used as steel guard plates, and the plastic plates are easy to cause electric leakage of the battery pack due to impact, so that great potential safety hazards exist;
SUMMERY OF THE UTILITY MODEL
The utility model provides a honeycomb sandwich protective plate which can solve the problems pointed out in the background technology.
The honeycomb sandwich protective plate comprises a protective plate body, wherein the protective plate body comprises a core plate and a laminating surface layer compounded on the surface of the core plate, the core plate is a thermoplastic core material, the laminating surface layer is a plurality of thermoplastic resin prepreg sheets paved together layer by layer, and inserts for preventing compression rebound are arranged on the surfaces of flanges on two sides of the protective plate body.
Preferably, the thermoplastic resin prepreg sheet is a continuous unidirectional fiber-reinforced thermoplastic resin prepreg sheet or a fiber fabric-reinforced thermoplastic resin prepreg sheet.
Preferably, the thermoplastic core material is a PP core material or a PC core material.
Preferably, the laminated surface layer is obtained by laminating 2-6 layers of thermoplastic resin prepreg sheets at 0 degree and 90 degrees.
Preferably, the core board is a honeycomb thermoplastic core material.
Preferably, the insert is a plurality of long fiber thermoplastic cylinders.
The utility model provides a honeycomb sandwich protection plate which has the advantages of small weight, low cost, good shock resistance, high strength and the like, and can effectively protect a battery and prevent unnecessary potential safety hazards.
