Description

Charger shell and fan anti-resonance structure for electric vehicle

Technical Field

The utility model relates to an electric motor car battery charger technical field, specifically speaking relates to a resonance structure is prevented with fan to charger shell for electric motor car.

Background

The electric bicycle charger generally uses a fan for heat dissipation, and the fan comprises a ball fan and an oil-containing fan; the ball bearing fan has high noise, long service life and price which is more than three times of that of the similar oil-containing fan, and is generally used in servers and industrial products. The only disadvantage of the oil containing fan being quiet is that oil needs to be added at intervals, otherwise the lack of oil lubricating the fan will produce a large vibration which tends to drive the charger housing to resonate together and thereby produce a very loud noise. The normal sleep of a person can be affected in the case of charging at night.

Because the charger is an electronic product, a common consumer cannot add oil to the fan, and the vibration generated by the fan is difficult to solve at present; however, the resonance generated by the fan and the housing can be reduced, so that the noise generated by the fan and the housing can be reduced to an acceptable level.
