The invention discloses a thermal-insulation, noise-reduction and damping car engine cover. The thermal-insulation, noise-reduction and damping car engine cover comprises an engine cover outer plate and an engine cover inner plate and is characterized in that the engine cover outer plate is fixed on the outer side of the engine cover inner plate in an overlapped manner, the inner side of the engine cover outer plate is provided with corrugated protrusions, a thermal-insulation coating film is arranged on the lower side of the corrugated protrusions, the engine cover inner plate is provided with a left boss, a central boss and a right boss, the left boss and the right boss are symmetrical relative to a central line, the periphery of each of the left boss and the right boss is provided withthree slots, the central boss is provided with two slots inside, and a sound-absorption block is arranged in each slot; the left and right sides of the engine cover inner plate are provided with fastening bosses, and the fastening bosses are provided with damping and buffering devices. The thermal-insulation, noise-reduction and damping car engine cover has the advantages that by the thermal-insulation coating film, a good thermal-insulation effect is achieved, part of heat can be reflected out at the same time, and heat transferred to an engine is reduced; the sound-absorption blocks in the slots can absorb noise during the operation of the engine, and a good noise-reduction effect is achieved; the damping and buffering devices arranged at the edges of the engine cover inner plate can favorably weaken the vibration of the engine cover during the traveling vibration of a car.
Description
technical field [0001] The invention relates to an engine cover, in particular to an automobile engine cover for heat insulation, noise reduction and shock absorption. Background technique [0002] With the development of automobiles, the requirements for individualized styling and creative design of styling will become higher and higher for structural design. Traditional structures need to be continuously innovated with the development of styling. The hood is a device used to protect the car engine and other car components. When the car is running, the engine will produce a lot of noise. The surface paint surface is aging and dull, or even peeling off, which affects the aesthetics of the car. [0003] Therefore, need a kind of heat-insulation noise reduction shock-absorbing car engine cover, to solve the deficiency that prior art exists. Contents of the invention [0004] The purpose of the present invention is to propose a heat-insulating, noise-reducing, and shock-abs...
