Problems solved by technology

In this plan, only the feasibility of the technology is considered, and no detailed plan is proposed for the specific implementation of the technology, and the plan can only be regarded as semi-closed, and the two ends of the shell are open. During use, because the open The type of shell makes the motor still vibrate violently and make a lot of noise, so it is not suitable for large-scale use
Especially because of the open structure, during the soldering process, there is a high probability that the solder will enter the casing and affect the main body of the motor. Therefore, the semi-closed structure is not suitable for mass production, and it cannot greatly improve the quality of the motor. the role of

Embodiment Construction

[0033] Such as figure 2 As shown, the casing in the present invention is a cuboid structure in the shape of a bucket, with one end open and the other end closed. The main purpose of this type of casing in the present invention is to completely seal the end cover assembly, stator assembly, and rotor assembly of the entire motor. Inside the casing, the exterior of the entire motor forms a whole, and one of its functions is to facilitate installation. A positioning concave hole is arranged in the center of the sealing end surface of the housing, and the concave hole is used for placing the oil storage sealing gasket. The inner diameter of the concave hole and the outer diameter of the bearing bracket have strict coaxiality requirements. A part of the height of the washer is embedded in the bearing bracket, and another part is embedded in the concave hole of the casing, and the height of the gasket protruding from the bearing bracket is equal to the height of the concave hole of...

Abstract

Disclosed is a low-noise high-vibration totally enclosed micro motor, comprising a shell. A stator assembly, a rotor assembly (6) and an end cap assembly (2) of the motor are arranged in the enclosed shell. An electrical terminal (1) of the end cap assembly is exposed out of a barrel-shaped shell. A bearing support (5) and an oil gasket (53) are additionally arranged in the direction of an oscillator (4) so that the noise level of the motor can be reduced and the production efficiency can be enhanced. The bearing support is closely combined with the shell via four convex walls (51) arranged at the periphery so that the bearing support is prevented from being separated. The content of lubricating oil contained can be saved by the oil gasket, effectively reducing noise.

Description

technical field [0001] The invention relates to the field of motors, in particular to a fully enclosed micro motor with low noise and high vibration. Background technique [0002] Micro vibration motors are mainly used in electronic products such as mobile phones, Smart-watches, Bluetooth devices, PADs, Notebooks, etc., to function as silent vibration reminders. The structure of the traditional SMD motor is generally that the vibrator is exposed, and the shell and the bracket are combined to fix the motor. During the motor assembly and testing process, the motor shaft failure after bending and the motor noise have always been troublesome problems for manufacturers and customers. [0003] In response to this problem, the applicant proposed a micro-motor and its support with application number 2015104651877, which encloses the main body of the motor by using a cuboid barrel-shaped shell. In this plan, only the feasibility of the technology is considered, and no detailed plan ...
