Problems solved by technology

However, although steel and other metal alloys can meet the strength requirements of camera shutters to a certain extent, the camera shutters made of steel and other metal alloys usually have a large mass, which is not conducive to improving the shutter speed.

Embodiment Construction

[0041] The shutter device and shutter blades provided by the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] see figure 1 and figure 2 , the first embodiment of the present invention provides a shutter device 100, the shutter device 100 is used to control the time when an external light enters a photographic device and illuminates the photosensitive element of the photographic device. When the shutter device 100 is opened, the external light can irradiate the photosensitive element, and when the shutter device 100 is closed, the shutter device 100 can prevent the external light from irradiating the photosensitive element.

[0043] The shutter device 100 includes a shutter substrate 10 , a connecting unit 14 , a first driving unit 16 , a second driving unit 18 and a shutter blade structure 12 .

[0044] The shutter substrate 10 is used to support the shutter blade structure 12 , the co...

Abstract

The invention provides a shutter device comprising a shutter blade structure. The shutter blade structure comprises at least one shutter blade which is formed by compounding a carbon nanotube structure and a polymer, wherein the carbon nanotube structure comprises a plurality of carbon nanotubes, and the adjacent carbon nanotubes are tightly connected through Van Der Waals force. The invention also provides a shutter blade.

Description

technical field [0001] The invention relates to a shutter device and a shutter blade, in particular to a shutter device and a shutter blade for a camera. Background technique [0002] The camera shutter is the time-controlled mechanism that allows the film to be properly exposed. In the early days of camera development, due to the low sensitivity of photosensitive materials, the required exposure time was very long, and the exposure time was controlled by installing and removing the lens cap. In recent years, with the continuous improvement of the sensitivity of photosensitive materials and shooting requirements, the requirements for the shutter speed of cameras are also continuously increasing. [0003] In the prior art, steel and other metal alloys are generally used as the material of the shutter blades. However, although steel and other metal alloys can meet the strength requirements of the camera shutter to a certain extent, the camera shutters made of steel and other...
