Description

Technical Field

[0001] This utility model relates to the field of non-contact heart rate detection technology, specifically a detachable non-contact heart rate detection device that adapts to ambient light. Background Technology

[0002] Non-contact heart rate measurement refers to detecting heart rate without physical contact using devices such as cameras and radar. Camera-based non-contact heart rate measurement detects heart rate by recognizing changes in facial color. The size of the captured face is crucial for non-contact heart rate detection, but traditional devices, due to their fixed cameras, cannot capture a larger facial area. In addition, the intensity of ambient light also greatly affects the accuracy of detection. In insufficient ambient light, the accuracy drops significantly. Existing camera-based heart rate measurement devices require the assistance of light in the dark to detect heart rate, which may affect the sleep state of the subject and make it impossible to obtain the heart rate during normal sleep.

[0003] To address the aforementioned issues, this invention provides a detachable, non-contact heart rate detection device that adapts to ambient light. Utility Model Content

[0004] The purpose of this invention is to provide a detachable, non-contact heart rate detection device that adapts to ambient light. A camera is connected to the top of the main unit, a touchscreen display is mounted on the front of the main unit, an ambient light sensor and a power switch are mounted above the display, a heat sink is mounted on the back of the main unit, a magnetic wireless charging device is installed at the connection between the main unit and the camera, a tripod clip is mounted at the bottom of the main unit, and a near-infrared light filter is mounted on one side of the main unit. The magnetic connection of the camera allows for more placement options, and the rotatable camera makes it easier to capture the target's face, improving detection accuracy. The ambient light sensor above the touchscreen display determines the intensity of the ambient light and automatically adjusts the brightness of the LED strip on the camera to maintain the optimal detection environment. To detect the subject's sleep heart rate in low-light conditions at night, a near-infrared light filter can be mounted on the camera. The near-infrared light is turned on when detection is needed without affecting the subject's sleep state, thus solving the problems in the prior art.

[0011] Furthermore, the ambient light sensor consists of two photoresistors, the power switch has a cuboid structure with a width smaller than the thickness of the touch screen, and the heat sink consists of 18 rectangular heat dissipation holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this invention, the magnetic connection of the camera device allows for more placement positions of the camera. Combined with the rotatable camera, it is easier to capture the frontal face of the target object, improving the detection accuracy.

A power switch 7 is installed on the upper right side of the display screen 3. A magnetic wireless charging device 8 is provided at the connection between the host 1 and the camera device 2. The magnetic wireless charging device 8 consists of a magnetic wireless charging port 810 and a magnetic wireless charging base 820. The magnetic wireless charging port 810 consists of a charging port 811 and a magnetic ring 812. The magnetic wireless charging base 820 consists of a charging base 821 and a limiting ring 822. The host 1 and the tripod base 4 are connected by a detachable connection structure 9. The detachable connection structure 9 includes a quick-release plate 901 and a gimbal 902. The gimbal 902 includes a buckle 903 and a groove 904. A heat dissipation plate 10 is provided on the back of the host 1.

[0022] like Figure 1 As shown, the host 1 and the camera device 2 are further connected by a magnetic wireless charging device 8, the host 1 and the touch screen 3 are electrically connected, the host 1 and the near-infrared light filter 6 are magnetically connected, the touch screen 3 and the ambient light sensor 5 are electrically connected, the touch screen 3 and the power switch 7 are electrically connected, the host 1 and the quick-release plate 901 are fastened by screw rotation, and the quick-release plate 901 and the gimbal 902 are connected by using a buckle 903 to fasten the quick-release plate 901 into the groove 904.

[0023] like Figure 1 , Figure 2 As shown, the host 1 and the camera device 2 transmit video signals via Bluetooth. Both the host 1 and the camera device 2 are equipped with Bluetooth modules. The LED light strip 203 consists of 36 LEDs and is symmetrically distributed around the camera. The near-infrared light 204 consists of two 850nm near-infrared lights and is symmetrical about the camera.

[0024] like Figure 1 , Figure 3 As shown, the ambient light sensor 5 consists of two photoresistors, the power switch 7 is a cuboid structure with a width smaller than the thickness of the touch screen 3, and the heat sink 10 consists of 18 rectangular heat dissipation holes.

[0025] The working principle of this utility model is as follows: First, the device is installed by mounting the quick-release plate 901 on the main unit 1, then snapping the quick-release plate 901 into the groove 904 of the gimbal 902, and closing the buckle 903. Finally, the camera device 2 is placed on the magnetic wireless charging base 820 of the main unit 1 to complete the installation. The main unit 1 is started by controlling the power switch 7.

[0026] It should be noted that when the camera device 2 cannot capture the subject's face when placed on the host 1, for example, when the subject is lying down, the camera device 2 can be placed in a position where the subject's face can be captured. The angle of the camera 201 can be rotated and adjusted to capture the subject's face to the greatest extent. Alternatively, the camera device 2 can be magnetically attached to any metal device using the magnetic ring at the bottom to provide more shooting angles.

[0027] It should be noted that if it is necessary to detect heart rate during sleep in low ambient light conditions at night, the near-infrared light filter 6 can be installed on the filter mounting ring 205 of the camera 201 in advance, and the night mode can be selected on the touch screen 3. When it is necessary to detect heart rate at night, the host 1 controls the camera device 2 to turn on the near-infrared light 204 to start shooting. The video signal is transmitted to the host 1 for analysis and then displayed on the touch screen 3 to complete the heart rate detection.
