The housing 7 includes a convex portion 11 extending outward in the first direction and a side portion 12 parallel to the first direction. The first temperature sensor 4 and the second temperature sensor 5 are respectively disposed on the front surface and the back surface of the boss portion 11. The size of the open slot 2 is configured to the size of the mobile terminal 6. Wherein the electronic device sends the temperature information to the mobile terminal 6 via the plug 3.
As shown in fig. 2, the rear surface of the housing 7 is further provided with an opening 13, and the opening 13 is used for avoiding the rear camera of the mobile terminal 6. The shell 7 is preferably made of plastic, silica gel, rubber and other materials with elasticity, so that the shell 7 can be bent to facilitate the connection of the plug 3 with the mobile terminal 6. Since the 70% of the first contact points of the fall are the four edges of the mobile terminal, the protruding portions 11 extending outward of the housing 7 in the first direction in the present application can reduce the impact on the mobile terminal 6 during the fall, and the inner space formed by the protruding portions 11 can be used for disposing the PCB.
The size of the open slot 2 is configured to the size of the mobile terminal 6, so that the positions of the first temperature sensor 4 and the second temperature sensor 5 can be fixed, and the external detection module is not easy to be touched by mistake compared with other external detection modules in the prior art, thereby reducing the measurement accuracy. The mobile terminal 6 is stably arranged in the electronic device 1, so that the mobile terminal and the electronic device are mechanically stable and are not easy to fall off, and the overall stability is improved. The rigidity or flexibility of the material of the shell 7 of the electronic device 1 can also play a role of a protective shell.
Fig. 3 is a schematic structural diagram of the electronic device 1 of the present invention used in cooperation with a mobile terminal 6. The electronic device 1 is provided with a first temperature sensor 4, a second temperature sensor 5, a switch 15, an a/D conversion unit 16, an MCU17, a first interface unit 18, and a power conversion unit 14. The MCU17 controls the switch 15 to switch the first temperature sensor 4 and the second temperature sensor 5 to work respectively according to the instruction sent by the user operating the mobile terminal 6.
The camera module 66 of the mobile terminal 6 includes a front camera and a rear camera. When the mobile terminal 6 is at the front of the camera, the MCU17 obtains an instruction through the first interface unit 18 to control the switch 15 to switch to the first temperature sensor 4. When the mobile terminal 6 uses the rear camera, the MCU17 controls the switch 15 to switch to the second temperature sensor 5 by the instruction obtained from the first interface unit 18. The first temperature sensor 4 or the second temperature sensor 5 transmits the acquired temperature information to the MCU17 through the a/D conversion unit 16. The MCU17 then transmits the acquired temperature information to the mobile terminal 6 through the first interface unit 18 for processing.

When the camera module 66 of the mobile terminal 6 photographs a subject to be measured, the analog imaging signal is amplified by the signal processing unit, and then image data 68 is formed by the processor 62. The image data generated by the processor 62 is supplied to a face recognition program stored in a memory 64 and a display control unit 63. The face recognition program is used to detect whether the subject is a human face or, when the subject is a human face, matches a predetermined area range or position. When the face recognition program determines that the face matches the face recognition range box 67, the face recognition program returns a trigger signal. The trigger signal driving processor 62 acquires the temperature information detected by the electronic device 1 through the second interface unit 61, indicates the body surface temperature of the forehead, and outputs body temperature data on the display unit 65.

The face recognition range box 67 is image data stored in the memory 64, which is substantially a white oval box drawn on a transparent background. The face recognition range box 67 is used to induce the user to limit the face image 68 captured by the camera module 66 to the face recognition range box 67 area to obtain face frame image data. Therefore, the phenomenon that the shooting angle is incorrect due to the fact that the handheld mobile terminal 6 is too close to the first temperature sensor 4 or the second temperature sensor 5 or the handheld mobile terminal 6 inclines by a specific angle, and then the temperature data of the forehead position of a human body are not detected by the temperature sensors is avoided. The display control unit 63 displays an image signal obtained by combining the face frame image data output from the processor 62, the body temperature data output from the processor 62, and the face recognition range frame 67 on the display unit 65. Preferably, the display control unit 63 may further adjust the display color of the body temperature data according to a preset value, for example, when the preset value is exceeded, the display color is displayed as a striking red color, so as to improve the user experience.
The display unit 65 is an LCD or OLED display of the mobile terminal 6.
The face recognition range box 67 is not constrained to be oval, and those skilled in the art will appreciate that the face recognition range box 67 may also be in the form of rectangular, square, circular, etc., which are connected in principle.
