Technical Field

The utility model relates to a thermal-insulated structure, especially a battery package thermal-insulated structure of range extending electric motor car.

Background

An automobile exhaust system refers to a system that collects and discharges exhaust gas, and generally consists of an exhaust manifold, an exhaust pipe, a catalytic converter, an exhaust temperature sensor, an automobile muffler, a tail pipe, and the like. The automobile exhaust system mainly discharges the exhaust gas discharged by the working of an engine, and simultaneously reduces the pollution and the noise of the discharged exhaust gas; the automobile exhaust system is mainly used for motor vehicles such as light vehicles, mini vehicles, passenger cars, motorcycles and the like.

The automobile exhaust system is arranged on a whole automobile chassis, and when the automobile works, the working temperature of the exhaust pipe is very high, so that parts around the exhaust system are easily damaged; generally, parts which are not heat-resistant are arranged around the exhaust pipe, so that necessary heat insulation measures need to be taken, but the whole vehicle configuration is more and more abundant, and the arrangement space of the chassis is limited; in the prior art, heat insulation is performed by adding a heat insulation piece on an exhaust pipe. But when the application was on the range extending electric motor car, because the other battery package that is equipped with of blast pipe, the blast pipe setting is on heat insulating part, and blast pipe and battery package are adjacent, and the thermal-insulated effect that leads to this kind of connected mode to play is not good to probably influence the security performance of whole car.

The second thermal shield separates the engine exhaust pipe from the battery pack, providing further protection to the battery pack.

Further, the second heat insulating member is made of an aluminum material. The aluminum material is convenient for heat transfer.

Furthermore, a sinking platform is arranged at the position where the second heat insulation piece is used for fixing the engine exhaust pipe, and the height of the engine exhaust pipe in the vertical direction is lower than that of the second heat insulation piece. The heat emitted by the engine exhaust pipe can be dispersed and guided through the heat insulation plate and can not be emitted to the surface of the battery pack.

Furthermore, the heat insulation plate is in a continuous concave-convex shape. The contact area of the heat insulation plate and the battery pack is reduced, the area of the heat insulation plate is increased, and the dissipation of heat is accelerated while the air passage of the battery pack is protected.

Furthermore, the part of the engine exhaust pipe is positioned on the positioning plate, and the part of the positioning plate for receiving the engine exhaust pipe is narrowed inwards. The size of the section of the engine exhaust pipe is smaller than that of the silencer, and the narrowing positioning plate can save the cost of the heat insulation plate.
