A PCB board is disposed inside the main body, and the shutter button and the supplementary light module are electrically connected to the PCB board. Preferably, the supplementary light can be switched in mode; for example, the supplementary light can have two supplementary light modes: a normal power constant-on supplementary light mode and a high-power flash supplementary light mode. In this mobile phone camera flash control device, the device is connected to the mobile phone. After the user sets the shooting angle of the mobile phone, the user presses the shutter button, the supplementary light of the device illuminates, and the device simultaneously sends a shooting command to the mobile phone.
[0006] Compared with existing technologies, the beneficial effects of this application are as follows: In this mobile phone camera flash control device, the device is connected to the mobile phone. After the user sets the shooting angle, the user presses the shutter button, and the flash lamp of the device illuminates. Simultaneously, the device sends a shooting command to the mobile phone, thus simultaneously achieving the functions of mobile phone shooting and flash illumination. No additional person is needed to set the flash lamp, saving manpower and improving efficiency. It also solves the technical problem of poor shooting results due to the low power of the mobile phone's own flash lamp.
[0007] Furthermore, a zoom-in button and a zoom-out button are also provided on the upper surface of the main body. In another embodiment, the zoom-in button and zoom-out button can be a zoom-out knob. The zoom-in button and zoom-out button are used to control the zoom adjustment during mobile phone shooting. The mobile phone camera flash control device is connected to the mobile phone. After the user sets the shooting angle of the mobile phone, the user presses the shutter button, the fill light of the mobile phone camera flash control device is turned on, and the mobile phone camera flash control device simultaneously sends a shooting command to the mobile phone. When the user presses the zoom-in button or the zoom-out button, the mobile phone camera flash control device controls the mobile phone to adjust the zoom, enlarging or reducing the mobile phone's shooting image. In addition to realizing mobile phone shooting and fill light on the mobile phone camera flash control device, it can also control the mobile phone to zoom in or out of the shooting image, allowing users to further adjust the shooting image through the mobile phone camera flash control device during shooting without having to switch to the mobile phone for zoom adjustment, thus improving efficiency.
[0008] Furthermore, a zoom-in key and a zoom-out key are also provided on the upper surface of the main body. The zoom-in key and the zoom-out key are electrically connected to the PCB board and are used to control the zoom adjustment when the mobile phone is shooting.
[0009] Furthermore, the PCB board is connected to a power supply, and a main control chip, a Bluetooth chip, and a transmitting antenna are disposed on the PCB board. The main control chip has a KEY1 pin electrically connected to the power button, a KEY2 pin electrically connected to the camera button, and TX and RX pins electrically connected to the RX and TX pins of the Bluetooth chip, respectively. The Bluetooth chip is connected to the transmitting antenna to connect to the mobile phone via Bluetooth. The main control chip and the Bluetooth chip are respectively electrically connected to the positive terminal of the power supply.
[0010] Furthermore, a power button for controlling the pairing of the Bluetooth chip with the mobile phone is provided on the upper surface of the main body, and the power button is electrically connected to the PCB board.

One end of each fill light is electrically connected to the positive terminal of the power supply, and the other end is electrically connected to the drain of the NMOS transistor via parallel resistors R3 and R7. The gate of the NMOS transistor is electrically connected to the main control chip via resistor R8. In one embodiment, the fill light mode is switched to a normal power constant-on fill light mode. Specifically, the fill light is a normal power fill light; when the mobile phone camera flash control device is working, the main control chip continuously sends a high level to the gate of the NMOS transistor to control the fill light to remain constantly on. In another embodiment, the fill light is switched to a high-power flash fill light mode. Specifically, the fill light is a high-power flash; the main control chip sends a high level to the gate of the NMOS transistor for a short time to control the flash. Because the high-power flash generates significant heat, it only operates for a short time, and the overall product's heat dissipation effect meets normal usage requirements.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0024] To achieve the above objectives, the technical solution of this utility model is as follows:
[0025] See Figures 1-7 As shown, this utility model provides a mobile phone camera flash control device. The mobile phone camera flash control device includes a main body and a supplementary light part extending along one side of the main body. A supplementary light module is disposed at the center of the supplementary light part. The supplementary light module includes a supplementary light 131 arranged in a ring. A power button 111 and a shutter button 21 are disposed on the upper surface of the main body. A PCB board is disposed inside the main body 11, and the power button 111, shutter button 21, and supplementary light module 13 are all electrically connected to the PCB board. Preferably, the supplementary light can be switched in mode. For example, the supplementary light can have two supplementary light modes: a normal power constant light mode and a high power flash supplementary light mode. The power button 111 is used to turn the mobile phone camera flash control device on and off, and the shutter button 21 is used to control the mobile phone to take pictures. After the user sets the shooting angle of the mobile phone, the user presses the power button 111, the mobile phone camera flash control device is connected to the mobile phone, and the user presses the shutter button 21, the supplementary light 131 of the mobile phone camera flash control device is lit, and the mobile phone camera flash control device simultaneously sends a shooting command to the mobile phone.
[0026] Compared with the prior art, the beneficial effects of this application are as follows: In this mobile phone camera flash control device, after the user sets the shooting angle of the mobile phone, the user presses the power button 111, the mobile phone camera flash control device connects to the mobile phone, and the user presses the shutter button 21, the fill light 131 of the mobile phone camera flash control device lights up, and the mobile phone camera flash control device simultaneously sends a shooting command to the mobile phone, thus simultaneously realizing the functions of mobile phone shooting and fill light 131 illumination. No other person is needed to set the fill light 131, saving manpower and improving efficiency. It also solves the technical problem of poor shooting effect caused by the low power of the mobile phone's own fill light.
[0027] Furthermore, a zoom-in button S5 and a zoom-out button S6 are also provided on the upper surface of the main body, both of which are electrically connected to the PCB board. In another embodiment, the zoom-in button S5 and the zoom-out button S6 can be a zoom-out knob 22. The zoom-in button S5 and the zoom-out button S6 are used to control the zoom adjustment when the phone is taking a picture. After the user sets the shooting angle of the phone, the user presses the power button 111, the phone's camera flash control device connects to the phone, the user presses the shutter button 21, the fill light 131 of the phone's camera flash control device lights up, and the phone's camera flash control device simultaneously sends a shooting command to the phone. When the user presses the zoom-in button S5 or the zoom-out button S6, the phone's camera flash control device controls the phone to adjust the zoom, enlarging or reducing the size of the captured image. Based on the mobile phone camera flash control device, which enables mobile phone shooting and fill light 131, the mobile phone camera flash control device can also control the mobile phone to zoom in or out of the shooting screen. This allows users to further adjust the shooting screen through the mobile phone camera flash control device during shooting, eliminating the need for users to switch to the mobile phone for zoom adjustment, thus improving efficiency.
[0028] Furthermore, the PCB board is connected to a power supply J2, and houses a main control chip U2, a Bluetooth chip U8, and a transmitting antenna E1. The KEY1 pin of the main control chip U2 is electrically connected to the power button 111, and the KEY2 pin is electrically connected to the camera button 21. The TX and RX pins of the main control chip U2 are electrically connected to the RX and TX pins of the Bluetooth chip U8, respectively. The sixteenth pin of the Bluetooth chip U8 is connected to the transmitting antenna E1 via resistor R23. The BAT pin of the main control chip U2 and the fourteenth pin of the Bluetooth chip U8 are electrically connected to the positive terminal of the power supply J2. After the user sets the shooting angle of the phone, pressing the power button 111 causes the main control chip U2 to control the Bluetooth chip U8 to pair with the phone via the TX and RX lines. Specifically, the Bluetooth chip U8 can send a pairing signal to the phone via the transmitting antenna E1 for Bluetooth pairing. In one working scenario, after Bluetooth pairing is complete, the main control chip U2 controls the Bluetooth chip U8 via the TX and RX lines, and the Bluetooth chip U8 sends a camera command to the phone. Preferably, the main control chip U2 can be MC32F7361A1J, and the Bluetooth chip U8 can be ST17H36B.
[0029] Furthermore, a zoom-in button S5 and a zoom-out button S6 are also provided on the upper surface of the main body. Both zoom-in and zoom-out buttons S5 and S6 are located on the PCB board. The KEY3 pin of the main control chip U2 is electrically connected to the zoom-in button S5, and the KEY4 pin of the main control chip U2 is electrically connected to the zoom-out button S6. After the user sets the shooting angle of the mobile phone, the user presses the power button 111. The main control chip U2 controls the Bluetooth chip U8 to pair with the mobile phone through the TX and RX lines. The main control chip U2 connects to the user's mobile phone through the Bluetooth chip U8. When the user presses the zoom-in button S5 or the zoom-out button S6, the main control chip U2 controls the mobile phone to adjust the zoom through the Bluetooth chip U8, thus zooming in or out of the mobile phone's shooting image.
[0030] Furthermore, a charging module is also provided on the PCB board. The charging module includes a TYPE-C interface J1 and a TP4054 chip U1. The VBUS pin of the TYPE-C interface J1 is electrically connected to the VIN pin of the main control chip U2 via resistor R1. The VBUS pin of the TYPE-C interface J1 is electrically connected to the fourth pin of the TP4054 chip U1. The third pin of the TP4054 chip U1 is electrically connected to the positive terminal of the power supply J2. The first pin of the TP4054 chip U1 is electrically connected to the CHRG pin of the main control chip U2. When the external power supply J2 is plugged into the TYPE-C interface J1, the fourth and third pins of the TP4054 chip U1 form a circuit, allowing the power supply J2 to be electrically connected to the power supply J2 through the VBUS pin of the TYPE-C interface J1 and the fourth and third pins of the TP4054 chip U1, thereby charging the power supply J2. In another embodiment, the TP4054 chip U1 can be replaced with an LR5108 chip.
[0031] Furthermore, the fill light module 13 includes multiple fill lights 131 connected in parallel and an NMOS transistor Q1. One end of each fill light 131 is electrically connected to the positive terminal of the power supply J2, and the other end of each fill light 131 is electrically connected to the drain of the NMOS transistor Q1 through parallel resistors R3 and R7. The gate of the NMOS transistor Q1 is electrically connected to the PWM1 pin of the main control chip U2 through resistor R8. In one embodiment, the fill light mode is switched to a normal power constant-on fill light mode. Specifically, the fill light 131 is a normal power fill light. After the main control chip U2 completes pairing with the user's mobile phone through the Bluetooth chip U8, the PWM1 pin of the main control chip U2 continuously sends a high level to the gate of the NMOS transistor Q1, the NMOS transistor Q1 remains continuously turned on, and the fill light module continuously forms a circuit to control the fill light 131 to remain constantly on. In another embodiment, the fill light 131 is switched to a high-power flash fill light mode. Specifically, the fill light 131 is a high-power flash. The PWM1 pin of the main control chip U2 sends a high level to the gate of the NMOS transistor Q1 for a short time, turning on the NMOS transistor Q1 for a short time. The fill light module forms a circuit for a short time to control the flash of the fill light 131. Because high-power flash lights generate a lot of heat, they only work for a short time. The overall heat dissipation of the product can meet the normal use requirements.
[0032] Furthermore, the PCB board also includes a first light-emitting diode (LED1) and a second light-emitting diode (LED2). The thirteenth pin of the main control chip U2 is electrically connected to the first LED1 through a resistor R10, and the fourth pin of the Bluetooth chip U8 is connected to the second LED2 through a resistor R11. The first LED1 is used to indicate the charging status, and the second LED2 is used to indicate the Bluetooth status. Preferably, when the external power supply J2 is plugged into the TYPE-C interface J1, the main control chip U2 detects the insertion of the external power supply J2 through its VIN pin, and the thirteenth pin of the main control chip U2 controls the first LED1 to flash. When the TP4054 chip U1 in the supplementary lighting mechanism detects that the first power supply J2 is fully charged, the TP4054 chip U1 sends a signal to the main control chip U2 through its first pin, and the main control chip U2 controls the first LED1 to remain constantly lit. Preferably, after the Bluetooth chip U8 completes Bluetooth pairing with the mobile phone, the Bluetooth chip U8 controls the second LED2 to light up.
