Description

Aperture switching device for lens of mobile device

An aperture switching device, especially an aperture switching device used in conjunction with the lens of a mobile device, in which in addition to the aperture of the lens itself, the aperture of the lens is replaced by the aperture switching device, so that the lens of the mobile device The aperture has the function of essentially switching the aperture.

Since the advent of smart phones, because smart phones have the function of taking photos and recording, the public has been accustomed to using mobile phones instead of cameras to take photos. Smart phones continue to introduce new ones. In particular, major mobile phone manufacturers have focused on the highest pixels and large apertures. The aperture of a mobile phone is a fixed aperture, and it cannot be reduced or enlarged like a normal camera lens.

Controlling the zoom of the aperture is to drive the movement of the aperture blades through the aperture motor, but because the size of the mobile phone is required to be thin and light, it is obviously not feasible to configure an aperture motor in the mobile phone, and there are related optical structures and components. To be installed in the mobile phone, even the aperture motor not only consumes a certain amount of power, but also considers how to dissipate the heat generated by the motor and components. The sum of these factors is to increase the internal storage and heat dissipation space of the mobile phone to solve the problem. This goes against the mainstream design of thin and light smartphones. Therefore, all smartphones use a fixed aperture, which makes the lens structure more streamlined and saves space for other component configurations.

In addition to the large space occupied by the aperture motor and the relatively large power consumption, another limiting factor is the aperture structure of the lens. For example, the common rainbow mode aperture is used to adjust the size of the aperture through the aperture blade. When the shutter is pressed, the aperture automatically zooms to the aperture size set by the user on the camera interface; structurally, the aperture blades are stacked one after another. Although the curved thin metal blades are very thin, they still have thickness, plus The lens combination of the lens itself, the lens may protrude out of the mobile phone, it is easy to scratch the lens, so the adjustment of the aperture cannot be realized on the smart phone.

The main purpose of the present invention is to provide an aperture switching device used with the lens of a mobile device, which does not use traditional aperture blades, and the drive mechanism does not use a motor, so the mechanism is very simple, and the overall mechanism can be miniaturized and suitable Installed in increasingly thin and light mobile devices.
