1. Technical Field
The present disclosure relates to adjustable connecting mechanisms and, particularly, to a adjustable connecting mechanism for a camera device.
2. Description of the Related Art
There are two types of camera modules defined by different imaging distance: the first camera module having an imaging distance of 12.5 mm and the second camera module having an imaging distance of 17.5 mm. Accordingly, there are two types of camera mount types: CS-type for the first camera module and C-type mount for the second camera module. CS-type mount threadedly mounts the first camera module directly on a mounting portion of the camera device. A common used camera device usually includes an adjusting ring with a height of 5 mm. If the second camera module is needed, a used may disassemble the first camera module and sleeve the adjusting ring on the mounting portion, and then threadedly mount the second camera module on the mounting portion, until the second camera module abuts the adjusting ring. The second camera module is raised 5 mm, and the second camera module is capable of imaging at a film in the body of camera device.
However, the adjusting ring has a small shape, often detaches from the camera device, and can be easily lost.
Therefore, there is room for improvement within the art.
The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the views, and both the views are schematic.
Referring to
The frame 21 includes a main body 211 and a mounting portion 213. The main body 211 defines an aperture 2111. The mounting portion 213 is a substantially cylindrical barrel, extending perpendicularly from an outer surface of the main body 211, and surrounding the aperture 2111. The mounting portion 213 forms a pair of positioning strips 2131 and an adjusting portion 2135 on an inner surface thereof. The adjusting portion 2135 is about 5 mm in length, and extends from the outer surface of the main body 211 along an axis of the mounting portion 213. Each positioning strip 2131 extends from one end to the other end of the mounting portion 213, along the axis thereof. The mounting portion 213 further defines two though holes 2133 facing and opposite to each other. Each through hole 2133 is equidistantly spaced between the two positioning strips 2131 along the circumference of an inner surface of the mounting portion 213.
The fixing member 23 is used for mounting a first camera module or a second camera module (not shown). The fixing member 23 is substantially a hollow cylinder, and forms a flange 230 substantially around an outer edge thereof. An outer diameter of the flange 230 is substantially equal to an inner diameter of the mounting portion 213. The fixing member 23 defines a pair of positioning slots 231 for receiving the pair of positioning strips 2131 and a receiving slot 233 for receiving the adjusting portion 2135. The fixing member 23 defines a first engaging portion 235 and a second engaging portion 237 corresponding to each through hole 2133. The first engaging portion 235 is adjacent to the flange 230, and the second engaging portion 237 is spaced from the flange 230. A distance between a center of the first engaging portion 235 and a center of the second portion 237 is about 5 mm. In the illustrated embodiment, the number of adjusting portions 2135 is only one, the first engaging portion 235 is a circular threaded hole, the second engaging portion 237 is the same as the first engaging portion 235. An imaginary line passing through the center of the first engaging portion 235 and the center of second engaging portion 237 is parallel to the axis of the mounting portion 213. In alternative embodiments, the center of the first engaging portion 235 and the center of second engaging portion 237 may not be in a line parallel to the axis of the mounting portion 213. However, the distance between the center of the first engaging portion 235 and the center of the second engaging portion 237 along the axis of the mounting portion 213 is still 5 mm. The number of the adjusting portions 2135 may be two or more, and these adjusting portions 2135 are asymmetrically distributed on an inner surface relative to a center of the mounting portion 213.
The locking screw 25, includes a threaded portion 251 and a head portion 253 at a distil end of the threaded portion 253.
If the second camera module is needed, and a user may assembly the adjustable connecting mechanism 100 in CS-type. The fixing member 23 is mounted in the mounting portion 213, each positioning strip 2131 is received in a receiving slot 231, and the adjusting portion 2135 abuts an end of the fixing member 23 away from the flange 230. The through hole 2133 of the mounting portion 213 is aligned to the second engaging portion 237. The threaded portion 251 of the locking screw 25 passes through the through hole 2133 and engages in the second engaging portion 237. The head portion 235 resists the fixing member 23, to fix on the mounting portion 213. Then the second camera module is mounted on the fixing member 23. The distance between the lens of the camera module and the film in the main body is about 17.5 mm, this is CS-type mount; and the second camera module is capable imaging at the film in the main body.
Referring to the
The adjustable connecting mechanism 100 includes a fixing member 23, the fixing member 23 defines the first engaging portion 235 and the second engaging portion 237 for mounting the fixing member, and the distance between the first and second engaging portions 235 and 237 along the axis of the fixing member 23 is 5 mm. The locking screw 25 is capable of engaging in the first engaging portion 235 or the second engaging portion 237, thus height of the fixing member 23 relative to the frame 21 can be adjusted, and the mount type of the adjustable connecting mechanism 100 can be easily switched. When the adjusting portion 2135 is received in the receiving slot 233, the fixing member 23 contacts the frame 211; this is CS-type mount. The adjustable connecting mechanism 100 can be adjusted when the adjusting portion 2135 deviates from the receiving slot 233, the adjusting portion 2135 abuts the fixing member 23, thus the fixing member 23 is raised 5 mm in height and switch to the C-type mount.
Finally, while particular embodiments have been described, the description is illustrative and is not to be construed as limiting. For example, various modifications can be made to the embodiments by those of ordinary skill in the art without departing from the true spirit and the scope of the invention as defined by the appended claims.
