VOICE COIL MOTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18598489 titled 'VOICE COIL MOTOR
The abstract describes a Voice Coil Motor (VCM) comprising a rotor with a cylindrical bobbin for holding a lens, a coil block, a stator with a magnet and yoke, and an elastic member with a disengagement prevention unit and coupling unit.
- The VCM includes a rotor with a bobbin for a lens and a coil block, as well as a stator with a magnet and yoke.
- An elastic member with a disengagement prevention unit and coupling unit is also part of the VCM.
- The disengagement prevention unit on the boss inhibits the elastic member from disengaging, ensuring stability.
- The coupling unit on the elastic member ensures a secure connection at the joint with the disengagement prevention unit.
Potential Applications: - Optical devices - Camera autofocus systems - Laser focusing mechanisms
Problems Solved: - Prevents disengagement of elastic member - Ensures stability and reliability in VCM operation
Benefits: - Improved performance and accuracy in optical devices - Enhanced durability and longevity of VCM components
Commercial Applications: Title: Advanced Voice Coil Motors for Optical Devices This technology can be utilized in various optical devices such as cameras, microscopes, and laser systems, enhancing their autofocus capabilities and overall performance in a commercial setting.
Questions about Voice Coil Motors: 1. How does the disengagement prevention unit contribute to the stability of the VCM? The disengagement prevention unit inhibits the elastic member from being disengaged, ensuring the VCM's stability during operation.
2. What role does the coupling unit play in the elastic member of the VCM? The coupling unit on the elastic member ensures a secure connection at the joint with the disengagement prevention unit, maintaining the overall integrity of the VCM.
Original Abstract Submitted
A VCM (voice coil motor) is disclosed, the VCM including: a rotor including a cylindrical bobbin for accommodating a lens and protruded at a bottom end with a boss, and a coil block arranged at a periphery of the bobbin; a stator including a magnet facing the coil block and a yoke fixing the magnet; and an elastic member including a first elastic member formed with a through hole coupled to the boss of the bobbin and a second elastic member coupled to an upper end facing the bottom end of the bobbin; wherein the boss is formed with a disengagement prevention unit inhibiting the first elastic member from being disengaged from the boss, and the first elastic member is formed with a coupling unit contacting a joint where the disengagement prevention unit and the coupling unit meet.
