Problems solved by technology

Generally speaking, when the lens cover covers the lens mechanism, the lens cover needs to be removed manually. This action will take some time, which may result in the inability to start the machine or press the shutter immediately, or because the user forgot to remove the lens cover. And miss the opportunity to capture the beautiful scenery

Embodiment Construction

[0017] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0018] Please refer to figure 1 , which shows the appearance of an image capture device according to an embodiment of the present invention. The image capture device 100 is, for example, a camera, video camera or other device with image capture function, which at least includes a lens group 10, the lens group 10 has an optical axis and includes a lens cover 110 and a lens mechanism 120, wherein the lens cover 110 can be covered Hold the lens mechanism 120 to protect the optical elements (not shown) in the lens mechanism 120, such as the lens, from accidents such as falling dust, scratches or liquid splashes.

[0019] Please refer to figure 2 , which shows figure 1 An exploded view of the lens cap. The lens cover 110 has a central axis (not shown) and includes a base 111 , two movable elements 112 , two elastic elements 11...

Abstract

A lens mechanism, a lens cover and a lens group using the same. The lens cap selectively covers the lens mechanism. The lens mechanism includes a casing and a sleeve. The housing has a first chamfered surface, and an extension surface of the first chamfered surface obliquely intersects with the optical axis. The sleeve is arranged in the casing. The lens cover includes a base and a movable part. The movable part is movably arranged on the base relative to the base along the radial direction and has a second chamfered surface. The extension surface of the second chamfered surface obliquely intersects with the optical axis. When the lens cover covers the lens mechanism, the second angled surface is in contact with the first angled surface. Since the geometric contours of the first angled surface and the second angled surface match, the contact area between the first angled surface and the second angled surface increases. When the sleeve pushes the base along the optical axis, the second angled surface is separated from the first angled surface along the radial direction and the optical axis direction.

Description

technical field [0001] The present invention relates to a lens mechanism, a lens cover and a lens group including the lens mechanism and the lens cover, and in particular to a lens mechanism, the lens cover and the lens group including the lens mechanism and the lens cover which can save effort to remove the lens cover. Background technique [0002] The lens cover of the traditional lens mechanism can cover the lens of the lens mechanism to protect the lens from being polluted by external impurities. Generally speaking, when the lens cover covers the lens mechanism, the lens cover needs to be removed manually. This action will take some time, which may result in the inability to start the machine or press the shutter immediately, or because the user forgot to remove the lens cover And miss the opportunity to capture the beautiful scenery. Contents of the invention [0003] The object of the present invention is to provide a lens mechanism, a lens cover and a lens group us...
