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 which comprises at least one shutter blade. The shutter blade comprises at least two carbon nano tube composite structures; each carbon nano tube composite structure is formed by compounding a carbon nano tube structure and a polymer; each carbon nano tube structure comprises a plurality of carbon nano tubes; the carbon nano tubes extend in preferred orientation of the same direction; and an intersection angle Alpha is formed between the extending direction of the carbon nano tubes of each carbon nano tube composite structure and the extending direction of the carbon nano tubes of the adjacent carbon nano tube, and Alpha is more than zero degree and less than or equal to 90 degrees. The invention further providesthe 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 a time-controlled mechanism that allows the photosensitive element to obtain the appropriate exposure. 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 shut...
