Description

Technical Field

[0001] This utility model relates to the field of camera module technology, specifically to a dual-camera module and electronic device. Background Technology

[0002] Currently, some electronic devices, such as laptops, support Windows Hello. Windows Hello is a biometric authentication method that allows users to log in to Windows devices using facial recognition, fingerprints, or a PIN (Personal Identification Number). When logging in via facial recognition, the infrared camera on the Windows device is required.

[0003] However, when the infrared lights in an infrared camera are working, the camera's temperature will continuously rise. If the temperature becomes too high, it can cause lens drift, resulting in abnormally blurry images, or even lens detachment, leading to product malfunctions. Therefore, it is necessary to prevent the infrared camera from overheating.

[0004] Therefore, how to provide a dual-camera module that can automatically achieve overheat protection has become an urgent technical problem to be solved. Utility Model Content

[0005] In view of this, in order to solve the above-mentioned technical problems, this utility model provides a dual-camera module and electronic device.

[0007] In a first aspect, this utility model provides a dual-camera module, comprising: a strip circuit board and a first camera, a second camera, an infrared lamp, a driver chip, an integrated chip, and a connector disposed on the strip circuit board;

[0008] The first camera, the second camera, the driver chip, and the connector are respectively connected to the integrated chip, and the driver chip is also connected to the infrared lamp;

[0009] When the driver chip reaches a preset temperature, it stops supplying power to the infrared lamp, and the infrared lamp stops working.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Currently, some electronic devices, such as laptops, support Windows Hello. Windows Hello is a biometric authentication method that allows users to log in to Windows devices using facial recognition, fingerprints, or a PIN (Personal Identification Number). When logging in via facial recognition, the infrared camera on the Windows device is required.

[0027] However, when the infrared lights in an infrared camera are working, the camera's temperature will continuously rise. If the temperature becomes too high, it can cause lens drift, resulting in abnormally blurry images, or even lens detachment, leading to product malfunctions. Therefore, it is necessary to prevent the infrared camera from overheating.

[0028] Based on this, the present invention provides a dual-camera module capable of automatically implementing overheat protection. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Figure 1 This is a structural schematic diagram of a dual-camera module provided in an embodiment of this utility model. (See diagram below.) Figure 1 As shown, this dual-camera module includes: a strip circuit board 11 and a first camera 12, a second camera 13, an infrared lamp 14, a driver chip 15, an integrated chip 16, and a connector 17 disposed on the strip circuit board 11.

[0030] The first camera 12, the second camera 13, the driver chip 15 and the connector 17 are respectively connected to the integrated chip 16, and the driver chip 15 is also connected to the infrared lamp 14.

[0031] After connector 17 draws power from an external power source, it supplies power to driver chip 15 and integrated chip 16. Integrated chip 16 controls the working status of the first camera 12 and the second camera 13. Additionally, integrated chip 16 also controls the working status of infrared lamp 14 through driver chip 15. Specifically, when integrated chip 16 determines that infrared lamp 14 needs to be turned on, it sends a lamp-on control command to driver chip 15 via its IIC (Inter-Integrated Circuit) bus. Driver chip 15 then drives infrared lamp 14 to operate according to the lamp-on control command.

[0032] The infrared lamp 14 can specifically be an LED lamp. During operation, its temperature continuously rises, causing the temperature of the driver chip 15 to rise as well. When the driver chip 15 reaches a preset temperature, it stops supplying power to the infrared lamp 14, and the infrared lamp 14 stops working. It should be noted that the driver chip 15 used in this invention is a conventional driver chip; the specific model of the driver chip is not limited here, as long as it can achieve the function of stopping power supply to the infrared lamp 14 when its own temperature reaches the preset temperature.

[0033] Figure 2 This is a schematic diagram of the circuit principle of a driver chip provided in an embodiment of this utility model. The driver chip is designated as U10, and the names and functions of each pin of the driver chip are shown in Table 1:

[0034] Table 1

[0035]

[0036]

[0037] The thermal shutdown threshold of this driver chip is 150℃, meaning that when the temperature of this driver chip reaches 150℃, it will automatically shut down to prevent overheating damage.

[0038] In practical applications, when a 5V power supply is applied to pin A3, the entire chip drives the infrared LED2 to operate continuously. Through the I2C interface on pins B3 and C3, the current source's startup rate is adjustable in 8 stages, with the adjustment level ranging from 100mA to 1.37A. To ensure the required brightness of the infrared LED2, the current is typically within a relatively large range. In this case, if heat dissipation is insufficient, the temperature of the driver chip may reach 150℃. At this point, the driver chip stops supplying power to the infrared LED2, and the LED2 stops working, thus achieving overheat protection. Capacitors C10, C11, and C12 are used for circuit filtering; resistor R20 connects the system ground of the infrared LED2 to the module's ground; and inductor L3 stores energy and, in conjunction with the switch on pin A1, achieves voltage reduction.

[0039] In addition, the dual-camera module of this utility model may also include: a microphone module; the microphone module is connected to a connector.

[0040] Specifically, the microphone module may include a first microphone 181 and a second microphone 182. The first microphone 181 and the second microphone 182 are respectively disposed at both ends of the strip circuit board 11.

[0041] Furthermore, the dual-camera module of this invention may also include: a shielding cover; an integrated chip and a driver chip disposed within the shielding cover. This protects the integrated chip and driver chip from external damage through the shielding cover.

[0042] Specifically, the shielding cover includes a first shielding cover 191 and a second shielding cover 192; the integrated chip 16 is disposed inside the first shielding cover 191; and the driver chip 15 is disposed inside the second shielding cover 192.

[0043] Based on a general inventive concept, this utility model also provides an electronic device, including: the dual-camera module as described above.

[0044] This utility model adopts the above technical solution, providing a dual-camera module, including: a strip-shaped circuit board and a first camera, a second camera, an infrared lamp, a driver chip, an integrated chip, and a connector disposed on the strip-shaped circuit board; the first camera, the second camera, the driver chip, and the connector are respectively connected to the integrated chip, and the driver chip is also connected to the infrared lamp; when the driver chip reaches a preset temperature, it stops supplying power to the infrared lamp, and the infrared lamp stops working. Based on this, since the driver chip stops supplying power to the infrared lamp when its temperature reaches the preset temperature, and the infrared lamp stops working, this utility model can automatically achieve overheat protection.

[0045] Specifically, this electronic device can be a laptop computer.
