FRICTION MEMBER FOR BRAKE MECHANISM AND CAMERA SHUTTER USING THE SAME |
摘要 |
A friction member for a brake mechanism in a camera shutter is provided. The friction member includes a carbon nanotube polymer composite. The carbon nanotube polymer composite includes a polymer and a carbon nanotube structure mixed with the polymer. The carbon nanotube structure includes a plurality of carbon nanotubes joined by van der Waals attraction force. The camera shutter using the friction member is also provided. The camera shutter includes a drive mechanism and a brake mechanism. The drive mechanism includes a blade driving lever having a moving path. The brake mechanism includes two abovementioned friction members and a brake lever clamped between the two friction members. The brake lever is located at a termination of the moving path to brake the blade driving lever. |
