[0025] This technical solution sets the application of the millimeter-wave radar detector body 11 and the infrared detection sensor 14. The millimeter-wave radar detector body 11 is used to detect the micro-movement of the human body, and the infrared detection sensor 14 projects the thermal image of the human body onto the display screen 13. When the infrared detection sensor 14 fails to detect the thermal image of the human body, the angle of the millimeter-wave radar detector body 11 can be adjusted by driving the cylinder 5 and the motor 2, which facilitates people's use.

[0026] Embodiment 2:

[0027] Based on Embodiment 1, as shown in the present utility model Figures 1-4 As shown, both sides of the top of the millimeter-wave radar detector body 11 are fixedly connected with fixing rods 16. The top of the fixing rods 16 is fixedly connected with a protective cover 17. Both sides of the top of the box body 3 are fixedly connected with vertical plates 18.

The bottom of the toothed plate 6 is fixedly connected with a first slider, and a first chute adapted to the first slider is opened at the center of the bottom inner cavity of the box body 3.

[0028] Adopting the above technical solution, through the fixing rods 16 and the protective cover 17, the top of the millimeter-wave radar detector body 11 can be protected and shielded from rain. Through the vertical plate 18, the limiting block 19 and the limiting groove 20, the overall rotation of the movable rod 9 and all the structures on the movable rod 9 can be made more stable. Through the first slider and the first chute, the movement of the toothed plate 6 in the front-back direction can be made more stable.

[0029] Embodiment 3:

[0030] As shown in the present utility model Figures 1-4 As shown, it is disclosed that the gear 8 meshes with the toothed plate 6. Both sides of the top of the movable rod 9 are provided with movable grooves 21 adapted to the movable rod 9. The output end of the motor 2 is sleeved with a fixed shell, and the fixed shell is fixedly connected with the bottom plate 1. Installation holes 22 are opened at the four corners of the top of the bottom plate 1. The front of the box body 3 is fixedly connected with a controller. Both sides of the bottom of the box body 3 are fixedly connected with support rods. The bottom of the support rods is fixedly connected with second sliders, and a second chute adapted to the second sliders is opened on the top of the bottom plate 1.

[0031] Adopting the above technical solution, through the movable groove 21, the normal operation of the movable rod 9 can be ensured. Through the fixed shell, the motor 2 can be protected. Through the installation holes 22, it is convenient for the user to install and fix the entire device. Through the support rods, the second sliders and the second chute, the overall rotation of the box body 3 and all the structures on the box body 3 can be made more stable.

[0032] The working principle of the present utility model is as follows: The millimeter-wave radar detector body 11 is used to detect the micro-movement of the human body, and the infrared detection sensor 14 is used to display the thermal image of the human body on the display screen 13. When the infrared detection sensor 14 fails to detect the thermal image of the human body, the cylinder 5 is actuated to drive the toothed plate 6 to move, the rotating rod 7 is driven to rotate by the gear 8, and the cross plate 10 and all the structures on the cross plate 10 are driven to rotate forward integrally by the movable rod 9 until the infrared detection sensor 14 can detect the thermal image. Then, the motor 2 is actuated to drive the box body 3 and all the structures on the box body 3 to rotate, and the angle is adjusted to an appropriate angle, which facilitates the use of people.
