Linear motor with flange edge structure

Abstract

The invention discloses a linear motor with a flange edge structure. The linear motor comprises an upper case and a lower cover; a spring, a mover module, a coil and a FPC board are arranged in each of the upper case and the lower cover; an upper end of the spring and the mover module are in welding connection; a first cell body for placing the FPC board is arranged on the lower cover, a first flange edge is formed at an upper end of the lower cover, multiple second cell bodies are arranged at an outside of the first flange edge, multiple third cell bodies corresponding to multiple second cellbodies are arranged at the outside of the spring, multiple inserting parts matched with the second cell bodies and the third cell bodies are arranged at the lower end of the upper case; an enduring surface matched with the spring is formed at an intersection of the inserting parts and the sidewall of the upper case. The vibration quantity of the motor is improved, the security and the reliabilityare high, the whole structure is compact and stable, the stability and a vibration effect are good, thereby improving the service life and applicable range of the motor, and the linear motor can be applied to a power source of tactile feedback of the intelligent equipment.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a linear motor with a flange structure. Background technique [0002] With the rapid development of electronic products, especially mobile terminal devices such as mobile phones and tablet computers, these electronic devices basically use vibration generators to prevent noise from electronic devices from disturbing others. The traditional vibration generating device uses a rotor motor based on eccentric rotation, which realizes mechanical vibration through the rotation of the eccentric vibrator. During the rotation of the eccentric vibrator, the commutator and brushes will generate mechanical friction and electric sparks, etc., which will affect The rotational speed of the eccentric vibrator further affects the vibration effect of the device. Therefore, current vibration generating devices mostly use linear motors with better performance. [0003] Linear motors, also known as lin...
