Detailed Description
The invention is further described below with reference to the drawings and examples.
Referring to fig. 1 to 3, the external lens holder for a handheld intelligent terminal includes: clip 1, lens support ring 2, lens adjusting ring 3.
The clamp 1 is provided with two opposite and parallel clamping parts 12, and the clamp 1 is n-shaped, wherein one clamping part 12 is provided with a lens mounting hole 11, and the other clamping part 12 is provided with a locking screw 13. In use, with reference to fig. 2 and 4, the clip 1 is secured to the handset 100 by screwing the locking screw 13, by clamping the handset 100 between the two clamping portions 12. It should be noted that the clip in the present invention is not limited to the above structure, and the clip may be a clip of various structures used in the existing external lens holder of a mobile phone.
Further, an elastic gasket 4 is respectively arranged at the inner end of the locking screw 13 and the inner end of the clamping part 12 where the lens mounting hole 11 is located, and the elastic gasket 4 is preferably a silica gel sheet or a rubber sheet so as to protect the surface of the mobile phone and increase the friction force with the surface of the mobile phone to ensure that the clamp 1 is firmly and reliably combined with the mobile phone.
The lens support ring 2 is disposed in the lens mounting hole 11 and is movable in the axial direction of the lens mounting hole 11. The lens supporting ring 2 has a receiving cavity 22 for receiving an external lens, and a light transmitting hole 21 provided at the bottom of the receiving cavity 22, the light transmitting hole 21, the receiving cavity 22 and the lens mounting hole 11 being concentric.
The lens adjusting ring 3 includes a tubular portion 31 for connecting with the lens mounting hole 11 and the lens supporting ring 2, and an outer flange 32 formed at an outer end of the tubular portion 31. The outer wall of the tubular portion 31 has a first thread, and the inner wall has a second thread, the pitch of the first thread is smaller than the pitch of the second thread, and the lens adjusting ring 3 is screwed with the lens mounting hole 11 through the first thread and the lens supporting ring 2 through the second thread.
Referring to fig. 2 and 4, when the lens adjusting ring 3 is rotated, the lens supporting ring 2 moves along the axial direction of the lens mounting hole 11 under the action of the second screw thread, so as to drive the external lens mounted therein to move, thereby adjusting the distance between the external lens and the mobile phone camera 101. Although the lens adjusting ring 3 has a slight displacement with respect to the lens mounting hole 11 by the first screw thread, the adjusting action is not affected because the pitch of the first screw thread is smaller than that of the second screw thread.
As another implementation mode, the outer end of the lens adjusting ring embedded in the lens mounting hole can rotate around the axis of the lens mounting hole, and threads are arranged on the inner wall of the lens adjusting ring and are in threaded connection with the lens supporting ring. When the lens adjusting ring is rotated, the lens supporting ring is driven to move along the axial direction of the lens mounting hole under the action of the threads, so that the external lens mounted in the lens supporting ring is driven to move, and the distance between the external lens and the mobile phone camera can be adjusted.
Still further provided are some embodiments of an external lens for a handheld intelligent terminal, which include a lens body and a lens holder, wherein the lens holder may be any of the external lens holders described above. The lens body can be assembled on the lens support ring 2 of the lens support in a threaded connection mode, can be assembled on the lens support ring 2 of the lens support in a buckling connection mode, and can be adhered and fixed in the lens support ring 2 of the lens support or fixed on the lens support ring 2 of the lens support in a magnetic attraction mode.
Still further, an external lens using method of the handheld intelligent terminal is provided, please combine fig. 2 and fig. 4, and the using method includes:
an external lens (not shown) is mounted at the camera 101 of the mobile phone 100 through an external lens bracket, wherein the external lens bracket comprises a clip 1, a lens supporting ring 2 and a lens adjusting ring 3, and the clip 1 is provided with a lens mounting hole 11; the lens support ring 2 is arranged in the lens mounting hole 11 and can move along the axial direction of the lens mounting hole 11; the lens adjusting ring 3 is rotatably assembled at the outer end of the lens mounting hole 11 and is in threaded connection with the lens supporting ring 2;
then, the camera software or the shooting software in the mobile phone is opened, and the lens adjusting ring 3 is screwed until the picture definition reaches the best.
The external lens bracket, the external lens with the external lens bracket and the using method can be applied to various handheld intelligent terminals such as mobile phones, tablet personal computers, IPAD and the like.
The foregoing detailed description of the invention has been provided by way of example only to assist those skilled in the art in understanding the invention and is not to be construed as limiting the scope of the invention. Various modifications, equivalent changes, etc. which are made by those skilled in the art to the above-described embodiments under the inventive concept should be included in the scope of the present invention.
