Description

Technical Field

[0001] The utility model relates to the technical field of vibration motors, in particular to a vibration motor. Background Art

[0002] Vibration motors, also known as vibration motors, are equipped with a set of adjustable eccentric blocks at both ends of the rotor shaft. The centrifugal force generated by the high-speed rotation of the shaft and eccentric blocks is used to obtain the exciting force. The vibration motor has a wide range of vibration frequencies. Only when the exciting force and power are properly matched can the mechanical noise be reduced. There are six types of vibration motors, including those classified by starting and running mode and those classified by running speed.

[0003] At present, the Chinese patent with the publication number CN213213205U discloses a vibration motor, including: an iron shell, a rubber cover is installed at the left end of the iron shell, a rotor is installed inside the magnetic ring, the rotor includes an iron core and an enameled wire winding wound outside the iron core, the enameled wire winding is composed of two groups of enameled wires connected in parallel, the right end of the stainless steel shaft passes through the eccentric wheel and the inner ring of the second oil-containing bearing, and the left end of the stainless steel shaft passes through the commutator and the oil baffle plate and is inserted into the inner ring of the first oil-containing bearing. The motor has an eccentric wheel built in, and the eccentric wheel moves inside the motor. The motor's axial force is jointly borne by the iron shell, the first oil-containing bearing, the second oil-containing bearing and the rubber cover, the bearing wear is small, and the motor life is improved; the motor runs at a high speed, and the centrifugal force generated by the high-speed rotation of the stainless steel shaft and the eccentric wheel is used to obtain the exciting force, thereby generating vibration. The vibration motor is an exciting source that combines the power source and the vibration source into one; the two groups of rotor windings are connected in parallel, the motor output power is twice that of the existing motor, and the product has a large vibration force.

[0004] Although the above-mentioned vibration motor solves the corresponding technical problems, it is found in actual use that the position of the eccentric wheel of the above-mentioned vibration motor cannot be adjusted, resulting in that its vibration performance is not easy to adjust. In addition, the vibrator of the traditional motor generally uses a light material, resulting in a small vibration intensity. Therefore, an improved vibration motor is proposed.
