Description
Technical Field
The utility model belongs to the technical field of the car backplate, concretely relates to backplate structure under engine for car.
Background
Automobile engine room bottom, because easy debris such as ponding, mud stone that are by the road surface strike, generally can dispose a backplate part, traditional backplate adopts the working of plastics more down, and its user demand that can satisfy the general condition, nevertheless because automobile engine work can produce a large amount of heats, and the working of plastics is for a long time in the environment of being heated, takes place the condition of ageing easily to its overall cost is also higher, so suitability and practicality receive the restriction.
Disclosure of Invention
The utility model aims at providing a structure sets up reasonable and suitability strong engine lower protective plate structure for car.
Realize the technical scheme of the utility model is an engine lower protective plate structure for car, including lower protective plate body, set up a plurality of on the lower protective plate body and keep away a slotted hole, the top surface integrated into one piece of lower protective plate body has the enhancement flange, the lower protective plate body includes middle part PP glass fiber board, the top surface compression molding of middle part PP glass fiber board has pure aluminium foil layer, the bottom surface compression molding of middle part PP glass fiber board has net aluminium foil layer, net aluminium foil layer is for punching the mixed structure body of aluminium membrane and latticed glass fiber silk.
The gram weight of the grid aluminum foil layer is 120g/m2And the thickness of the grid aluminum foil layer is 2-10 mm.
The thickness of the pure aluminum foil layer is 3-6 mm, and the gram weight of the pure aluminum foil layer is 200g/m2。
The weight of the middle PP glass fiber plate is 900-1100 g, and the thickness is 10-20 mm.
The utility model discloses has positive effect: the utility model discloses a structure sets up rationally, and it not only has better thermal-insulated effect to can bear higher temperature, still have better waterproof performance simultaneously, use reliable and stable, the suitability is strong and the practicality is good.
