Embodiment Construction

[0019] In addition to micro-projectors, the present invention can also be applied to general projectors, cameras, mobile phones and other electronic devices with lenses. The lens protection cover is used to link the power switch and lens. When the lens protection cover is opened, it is equivalent to turning on the Action, when it is turned on, it is just ready to perform focusing action.

[0020] see figure 1 The electronic device of the present invention includes a frame 70, a cover plate 60, a power switch 50, a lens 40, a spring 30, a lens focus lever 20 and a lens protection cover 10, and each component is described as follows:

[0021] The lens 40 is movably installed in the frame 70 and can be moved along its optical axis (ie ±X direction) to adjust the focus. The lens 40 includes a lug 402 .

[0022] The lens focus lever 20 is installed on the shaft portion 702 of the frame 70 through the shaft hole 206 , so that the lens focus lever 20 can rotate around the shaft por...

Abstract

The invention relates to an electronic device which comprises a shot, a shot focusing rod, a power supply switch and a shot protecting cover. The shot focusing rod is connected with the shot so as to drive the shot to move along an optical axis for focusing. The shot protecting cover can move in a direction perpendicular to the optical axis among a first position, a second position and a third position; in the first position, the shot protecting cover shields the shot, the power supply switch is off, and the shot protecting cover is separated from the shot focusing rod; in the second position, the power supply switch is on, and the shot protecting cover is contacted with the shot focusing rod; when the shot protecting cover moves between the second position and the third position, the power supply switch is on, and the shot protecting cover drives the shot to focus via the shot focusing rod.

Description

technical field [0001] The present invention relates to an electronic device, in particular to an electronic device which uses a lens protection cover to link a power switch and a lens. Background technique [0002] Micro projectors are smaller and lighter than ordinary (traditional) projectors, and are very convenient to use and store, so they are getting more and more attention from the market. [0003] However, in order to save costs, the micro projector often omits some components and functions, such as lens protection cover and power switch. On the other hand, if these functions are deliberately designed, not only the cost will increase, but also the volume will increase, and the design complexity will also increase. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an electronic device for the above-mentioned defects of the micro-projector in the prior art, which utilizes a lens protection cover to link the ...
