Abstract
A vibration motor with a built-in end cover relates to a vibration motor. Presently, a casing of a vibration motor comprises an end housing, a base and an end cover. A screw penetrates sequentially through the end housing and the end cover to be in fixed connection with the base. A bearing of the vibration motor is often blocked during operation and consequently, the vibration motor is burnt out and can not be used. Moreover, the integral property of the appearance is poor, cost is high, and processing difficulty is large. The vibration motor with the built-in end cover comprises a base, a motor shaft, an end cover and an end housing, and is characterized in that the end cover and the end housing are respectively fixed on the end face of the base through a connection component and the end cover is disposed inside the end housing. A driving eccentric block and a driven eccentric block are in sleeve connection with the shaft on the outer side of the end cover. The end cover is disposed inside the base and the end housing, and is no longer a part of the casing. Accordingly, integrity of the motor is enhanced. Material range of the end cover is enlarged, cost is reduced, quality of the vibration motor is improved, noises of the bearing are lowered and service life is prolonged.
