Abstract

The invention provides a linear motor. The linear motor comprises a shell and a vibration assembly. The vibration assembly is located in the shell. Gaps are formed between the left and right sides of the vibration assembly and the inner wall of the shell; the opening directions of V-shaped springs on the left side and the right side of the vibration assembly are opposite or in the same direction; each V-shaped spring comprises a corner end, a first connecting arm and a second connecting arm; and the end of the first connecting arm is fixed to the inner wall of the shell, the end of the second connecting arm is fixed to the outer wall of the vibration assembly, a gap is reserved between the outer wall of the corner end and the inner wall of the shell, and the space between the first connecting arm and the inner wall of the machine shell and / or the space between the outer wall of the second connecting arm and the outer wall of the vibration assembly are / is filled with first damping parts. Dampers are added between the outer walls of the springs and the shell or the vibration assembly and at the corner ends of the springs, and the dampers work independently or are matched with one another to obtain dampers with different sizes and different effects.

Description

technical field [0001] The invention relates to the technical field of linear motors, in particular to a linear motor. Background technique [0002] Due to the inherent simple harmonic vibration characteristics of linear motors, if there is no additional damping, the residual vibration of the product will be delayed for a long time, and the stop time will be very long, resulting in various restrictions in practical applications. [0003] In the prior art, technical solutions such as magnetic fluid, electromagnetic or foam are often used to realize the damping control of the linear motor. For example, a linear vibration motor disclosed in the application number 201820162109.9, the linear vibration motor includes a casing, a vibrator part, a stator part, and two first metal shrapnels, and the first metal shrapnels include first and second fixed pieces facing left and right and a U-shaped connecting piece connecting the first and second fixing pieces, the first fixing piece is...
