Problems solved by technology

The external flash receives the flash signal from the main control unit to flash through the control signal, and is only used to flash when taking pictures.
[0004] The external flash used in existing mobile phones and the mobile phone are generally two independent entities, which is inconvenient to use, and the existing smart phones can only select functions by clicking the menu on the screen, which cannot be accessed through external function buttons. Make quick adjustments to its shooting functions

Embodiment 1

[0060] refer to Figure 1 to Figure 3 , the present invention is an external flashlight for assisting mobile phone photography, which is installed on the mobile phone 17 and includes: a body part 1 and a deck 5 . An accommodating cavity 6 is provided on the inner surface of the fuselage part 1 . The card holder 5 is movably installed in the accommodating cavity 6 , and the accommodating cavity 6 and the card holder 5 are fixed through the cooperating chute 7 or buckle 20 . The deck 5 is used for fixing with the mobile phone 17 . Since the card holder 5 is movably installed in the accommodating cavity 6 of the body part 1, it can replace the card holder 5 of different specifications to adapt to different brands and models of mobile phones. In other embodiments, the card holder 5 can be eliminated, and the mobile phone is directly placed in the accommodating cavity 6 of the fuselage.

[0061] The body part 1 is provided with a grip part 2 and a multifunction button for inputt...

Embodiment 2

[0084] refer to Figure 7 The difference between the external flashlight of this embodiment and the structure of Embodiment 1 is that the lens module 9 is installed on the slide rail 8 or the buckle plate 22 through the fastener 21; Select a suitable lens module 9 according to one's own needs, and install the required lens module 9 on the slide rail 8 through the fastener 21 to achieve its shooting effect. Others are consistent.

[0085] refer to Figure 8 (The power supply unit is not shown in the figure). The shooting scene requires multiple external flashes with different flash durations to meet the requirements of different photo effects.

[0086] The mobile phone is connected to an external flashlight 1 that assists mobile phone shooting in this application through WIFI or Bluetooth, and the external flashlight 1 is connected to the external flashlight 4, the external flashlight 5, the external flashlight 6 and the external flashlight 7 through a 2.4GHz wireless module ...

Embodiment 3

[0099] The shooting scene requires multiple external flashes with different flash sequences to meet the requirements of different photo effects.

[0100] refer to Figure 10 The difference between this embodiment and Embodiment 2 is that the external flash 4, the external flash 5, the external flash 6 and the external flash 7 in this embodiment also include an input unit and the frequency value control signal is set in this embodiment Inconsistent with the flash sequence signal, other signals are consistent. Wherein, the frequency value control signal, the power signal and the strobe signal are input through the input unit. The settings of other signals are set through the flash control signal of the mobile phone.

[0101] In the flash control signal, the external flash 1 and the external flash 4 flash at first, followed by the external flash 5, and finally the external flash 6 and the external flash 7 flash simultaneously. The frequency value control signals of external fl...
