Description
Technical field
The utility model relates to automobile industry technical field, more specifically, relates to a kind of engine noise reduction mechanism.
Background technique
Along with the progress of modern science and technology, automobile is more and more towards safety, comfortable future development.But car engine chance produces very large noise, the source of noise mainly contains: the vibration that mechanical noise is produced under unbalanced force and moment loading by rotating motion part and reciprocating part, shock between movement parts, frictional force and pulse pneumatic encourage the structural vibration caused of various mechanism member and the noise of radiation; Combustion noise sends out formed impact and the cyclically-varying of pressure by cylinder combustion decrepitate, and cylinder causes structural member to vibrate to pass to Internal Combustion Engine by outside and internal communication approach and produces; Aerodynamic noise comprises air inlet and exhaust piper and fan noise, and gas expansion forms turbulent flow spray noise, flow disturbance noise.
In prior art, the noise produced for motor does not carry out conversion, causes noise to produce great harm to driver and passenger, and causes damage of components for motor itself because noise produces vibration, and maintenance cost increases.
Summary of the invention
The utility model, for overcoming at least one defect described in above-mentioned prior art, provides a kind of engine noise reduction mechanism, and structure is simple, effectively can eliminate the noise that motor produces in running.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
There is provided a kind of engine noise reduction mechanism, comprise the casing be sheathed on outside motor, described casing is made up of piezoelectric ceramic plate, and described piezoelectric ceramic plate is provided with snakelike guiding groove, is provided with electrical power storage pipe in described guiding groove.
Further, described piezoelectric ceramic plate comprises internal layer and skin, and described snakelike guiding groove is arranged on described internal layer.The setting of internal and external layer, can exclude noise further, and can fully piezoelectric ceramic plate be collected and the energy storage changed in electrical power storage pipe.
Further, described electrical power storage pipe connects an electric energy accumulator.
Compared with prior art, the beneficial effects of the utility model are:
The structure of the utility model engine noise reduction mechanism is simple, effectively can eliminate the noise that motor produces in running, and be converted into electric energy, both reduce the infringement of noise to driver health, electric energy can be provided for mobile phone, cigar lighter again, economize on resources.
Accompanying drawing explanation
Fig. 1 is the structural perspective of the utility model embodiment engine noise reduction mechanism.
Embodiment
Below in conjunction with embodiment, the utility model is further described.
Be illustrated in figure 1 the embodiment of the utility model engine noise reduction mechanism, comprise the casing be sheathed on outside motor, casing is made up of piezoelectric ceramic plate, and piezoelectric ceramic plate is provided with snakelike guiding groove 2, is provided with electrical power storage pipe (not shown) in guiding groove 2.
In the present embodiment, piezoelectric ceramic plate comprises internal layer 1 and outer 3, and snakelike guiding groove 2 is arranged on internal layer 1.The setting of internal and external layer, can exclude noise further, and can fully piezoelectric ceramic plate be collected and the energy storage changed in electrical power storage pipe.
Collecting to utilize piezoelectric ceramic plate more fully and the energy changed, during actual use, electrical power storage pipe being connected an electric energy accumulator, effectively to collect and to use the electric energy changed.
The structure of the present embodiment engine noise reduction mechanism is simple, effectively can eliminate the noise that motor produces in running, and be converted into electric energy, both reduce the infringement of noise to driver health, electric energy can be provided for mobile phone, cigar lighter again, economize on resources.
