Portable communication device

The invention relates to a communication device, in particular to a portable communication device with a lens module.

With the continuous development of Internet multimedia technology, digital cameras have been widely used, especially in recent years, mobile communication devices such as mobile phones have also rapidly developed into high-performance and multi-functional directions, and mobile communication devices such as mobile phones with camera functions have appeared. That is, the combination of the mobile phone and the camera enables the portable communication device to perform the functions of the camera in addition to its own functions.

Most of the cameras of portable communication devices use fixed-focus optical lens groups. Because the aperture of the camera used is not large, the depth of field is long. When shooting a distant view, even if it is not properly focused, the effect will not be too bad. However, if a close-up shot is taken, because the magnification of the camera is large, the phenomenon of the focus is not accurate, and the object being photographed will be blurred.

In view of the above, it is necessary to provide a portable communication device that can clearly capture close-ups.

A portable communication device includes a body, a lens module disposed in the body, and a focusing assembly. The body includes a housing, and the housing is provided with a guiding groove penetrating the housing. The focusing assembly includes a convex lens and an operating member, and the operating member is slidably received in the guiding groove. And the sliding of the operating member enables the convex lens to switch between the two positions directly above the lens module and the lens module side.

The above-mentioned portable communication device adjusts the focal length of the lens module by providing a convex lens that can be switched between the two positions directly above the lens module and the lens module side directly above the lens module. When the object scene is far away from the lens module, the convex lens is located on the lens module side by operating the operating member; when the object scene is close to the lens module, the operating lens is operated in the opposite direction, so that the convex lens is located in the lens module. Directly above, the light passes through the convex lens and then enters the lens module to obtain a clear image.

The lens module 20 includes a lens barrel 21, a lens group 22, an infrared filter 23, a photosensitive element 24, and a printed wiring board 25.

A light-passing hole 211 is defined in the center of the lens barrel 21. The light-passing hole 211 is slightly smaller than the light-transmitting hole 13 in the body 10, and can be disposed coaxially with the light-transmitting hole 13 on the body 10. The light-passing hole 211 is used to pass external light. . A bracket 212 is provided around the inner wall of the lens barrel 21, and the holder 212 is used to position the lens group 22. The infrared filter 23 is disposed below the lens group 22. The photosensitive element 24 and the printed wiring board 25 are sequentially disposed at the bottom of the lens barrel 21. The photosensitive element 24 in this embodiment is a charge coupled device (CCD), and may of course be an additional metal oxide semiconductor device (COMS).

The focusing assembly 30 includes a convex lens 31, an operating member 32, and a connecting rod 33. The convex lens 31 is received in a gap between the lens module 20 and the housing 11, and the convex lens 31 is movable in the gap. The operating member 32 is movably received in the guide groove 12 of the housing 11. The movement of the operating member 32 can drive the convex lens 31 to move. The connecting rod 33 is fixed to the operating member 32 at one end and fixed to the lower edge of the convex lens 31 by the other end, and the extending direction of the connecting rod 33 and the extending direction of the guiding groove 12 intersect, in this embodiment, the connecting rod 33 The extending direction and the extending direction of the guide groove 12 are perpendicular to each other. It can be understood that the connecting rod 33 One end may be fixed to the side edge of the convex lens 31, and the other end may be fixed to the operating member 32. The guiding groove 12 facilitates the movement of the operating member 32 and also controls the moving stroke of the operating member 32, thereby controlling the convex lens 31 to move directly above the lens module 20 or directly above the lens module 20. Of course, the guiding groove 12 can also be curved.

Referring to FIG. 4, when shooting a distant object, the operating member 32 is located at the left end of the guiding slot 12, and the convex lens 31 is located at the lens module 20 side.

When the operating member 62 is moved to the uppermost end of the guiding groove 42, the convex lens 61 is located just above the lens module 50. When the operating member 62 is moved to the lowermost end of the guiding groove 42, the convex lens 61 is located on the side of the lens module 50. Therefore, the convex lens 61 is realized to be switched between the two positions directly above the lens module 50 and the lens module 50 side.

Referring to FIG. 9 and FIG. 10, the portable communication device 300 of the third embodiment of the present invention is similar to the portable communication device 100 of the first embodiment, except that the convex lens 91 is connected and The connecting member of the operating member 92 is a bending type rotating member 93. The bending type rotating member 93 includes two arms (not shown), the angle between the two arms is a fixed value, and the bent type rotating member 93 is bent. A fixed shaft 94 is provided, and the shape of the guide groove 71 formed in the portable communication device housing 70 is a part of a circular arc. The movement of the movement operating member 92 along the guiding groove 71 causes the two arms (not shown) of the bending type rotating member 93 to rotate with the fixed shaft 94 as a fixed point, thereby realizing the convex lens 91 directly above the lens module 80 and the lens module side. The positions switch to each other. In this embodiment, when the operating member 92 is located at the left side of the guiding slot 71 of the housing 70, the convex lens 91 is turned directly above the lens module 80. When the operating member 92 is located at the right side of the guiding slot 71, the convex lens 91 is rotated away from the lens module 80. Directly above. It can be seen that the convex lens 91 can be switched between the two positions directly above the lens module 80 and the lens module side by connecting the operating member 92 and the convex lens 91 by other connecting members.

It can be understood that the elastic piece can be further disposed at both ends of the guiding groove of the housing, so that the operating member can be easily pulled and the operating member can be positioned on the left side or the right side, so that the convex lens can be directly above the lens module and the lens module. The two positions on the side switch to each other. Of course, it is also possible to use an elastic operating member to maintain the stability of the operating member and the edge of the guiding groove by utilizing the elasticity of the operating member itself.
