Title:
LINEAR ELECTRIC MOTOR AND LINEAR VIBRATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/012266
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are a linear electric motor and a linear vibration device. The linear electric motor comprises a top cover assembly, a bottom cover assembly, a stator assembly and a rotor assembly, wherein the stator assembly comprises winding iron cores (6), magnetic conductive iron cores (7) and wire winding frames (5); the rotor assembly comprises a rotor support (33), a transmission rod (32) and magnetic bodies (4); the rotor support (33) is slidably arranged in a middle cavity of the stator assembly; the transmission rod (32) of the rotor support (33) extends out of an opening in a central position of an electric motor cover; the magnetic bodies (4) are further assembled inside the rotor support (33); a head of the transmission rod (32) is provided with a snap-fit position; and a coupling head (31) is snap-fitted with the snap-fit position, so as to complete coupling. According to the present invention, the linear electric motor has a simple and stable structure, is convenient to assemble, and reduces costs; the magnetic bodies are added, so as to reduce the number of coil windings on the stator assembly, thereby reducing wire loss and energy consumption, and improving the efficiency of the electric motor; the electric motor is coupled with a load by means of the coupling head to achieve linear vibration, and has a wide application range; and a developed product has unique performances, and great economic and social values.
