Based on the above mobile terminal hardware structure and communication network system, various embodiments of the present application are provided.

First embodiment

Please refer to fig. 3, which is a schematic diagram illustrating a flash module according to a first embodiment. The flash module 40 of the present embodiment includes a light emitting element 400, a light guide 410, an adjustment member 420, and a supporter 430. The light emitting element 400 may be a light emitting element such as an LED, and one side thereof is fixed to the holder 430, and the other side thereof is a light emitting side. The light guide 410 is disposed on the light emitting side of the light emitting element 400, and guides the light emitted from the light emitting element 400 such that the light passes through the light transmitting sheet 440 to form a light focus. The light-transmitting sheet 440 may be a lampshade or a soft light sheet.

In one embodiment, the center of the side of the light guide 410 near the light emitting element 400 is provided with a hole for accommodating the light emitting element 400, the hole being slightly larger than the sectional area of the light emitting element 400 to reduce light loss in the light guide 410. The light guide 410 is hollow inside, and the circumferential inner surface of the light guide 410 is opaque and coated with a light reflecting material to reflect light emitted from the light emitting element 400. The area of the side surface of the light guide 410 close to the light emitting element 400 is smaller than the area of the side surface far from the light emitting element 400, and the inner surface of the peripheral side of the light guide 410 is a concave mirror for light reflection, so that the light of the light emitting element 400 is converged inside the light guide 410 and forms a focus outside the light transmitting sheet 440.

Optionally, the adjusting component 420 is connected to the light guide 410 and/or the light emitting element 400, and is used for adjusting the relative position, including the relative angle and/or the relative distance, between the light emitting element 400 and the light guide 410, so that the guiding angle of the light emitted by the light emitting element 400 by the light guide 410 is changed to change the position of the light focus.

In one embodiment, the adjustment assembly 420 is coupled to the light guide 410. The adjusting assembly 420 is movably fixed on the bracket 430, the light guide 410 is fixed on the adjusting assembly 420, and the light guide 410 can move under the driving of the adjusting assembly 420 to adjust the relative distance between the light emitting element 400 and the light guide 410. Optionally, the adjustment assembly 420 includes a zoom motor 422 and a guide coil 421, the guide coil 421 being fixed to the support 430. The zoom motor 422 and the guide coil 421 are respectively provided with threads matched with each other, and the zoom motor 422 and the guide coil 421 are connected through the threads to accurately move the zoom motor. When the guide coil 421 is energized, the zoom motor 422 reciprocates in the holder 430 in the axial direction of the guide coil 421. The light guide 410 is disposed on the zoom motor 422, and the zoom motor 422 moves on the support 430 to drive the light guide 410 to move synchronously, so as to change the distance between the light guide 410 and the light emitting element 400.

The light emitting element 400 and the bracket 430 are fixed, and the light guide 410 and the adjusting assembly 420 can be regarded as a zoom module as a whole, and the zoom module reciprocates in the bracket 430 to adjust the relative distance between the light guide 410 and the light emitting element 400, so as to change the focal distance during light supplement of the flash module 40. In practical application, the zoom module can be installed in a mobile terminal alone, and the change of the flash focal length is realized by changing the position relationship between the light-emitting element 400 and the zoom module in the mobile terminal through movement. Alternatively, the flash module 40 in the present embodiment may be integrally incorporated in the mobile terminal, simplifying the assembly operation.

Referring to fig. 4, the light guide 410 is driven by the adjusting assembly 420 to approach the light emitting element 400, so that the focal position of the flash module 40 moves. Therefore, the flash focal length of the flash module 40 in fig. 4 is smaller than that in fig. 3. In practical implementation, the focal length of the flash lamp module 40 in fig. 4 can be used to match with a shot close-range image, so that light is uniform during shooting of the close-range image, the light supplement range is wide, and the problem that the center of the image is overexposed and dark corners exist around the image due to the fact that the focal length of the flash lamp is too long during shooting of a wide-angle image can be effectively avoided.

When taking a picture, after the camera module 50 is focused, the flash module 40 which needs to be used correspondingly is determined according to the angle range to which the focal length of the camera module 50 belongs. Then, the relative distance between the light guide and the light emitting element in the flash module is adjusted to make the flash focal length consistent with the photographing focal length, and the rest of the flash modules 40 are kept closed. For example, when the photographing device photographs a distant view, the focal length of the camera module 50 is the third focal length, and then the third focal length flash module is controlled to operate, so that the flash focal length is consistent with the photographing focal length, and then light is supplemented, and other flash modules are kept closed.
