Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Referring to FIG. 2 , it is a schematic structural diagram of a heart rate detection device provided by an embodiment of the present invention. The heart rate detection device includes a body 10 , and the body 10 includes a face shell 11 and a bottom shell 12 that are engaged with each other. The front shell 11 and the bottom shell 12 are fastened together by means of buckle, etc., so as to form the main body 10 and cover the components inside the main body 10 .

Referring to FIG. 3 , the surface of the face shell 11 is made of translucent acrylic material and is provided with a display screen 110 . The body 10 is provided with a heart rate detection module 13 with a heart rate sensor 131, and a circuit board (not shown) connected to the heart rate sensor 131 and the display screen 110. The circuit board is preferably a PCB board, and the PCB board It is preferably fixed on the inner surface of the bottom case 12 . The body 10 is also provided with a heart rate detection module driving device 14 and a heart rate sensor starting device. The heart rate detection module 13 moves up and down under the action of the heart rate detection module driving device 14, and the heart rate detection module 13 moves downward Move and protrude from the bottom shell 12 (the bottom shell 12 is provided with a through hole to pass through the heart rate detection module 13) to trigger the heart rate sensor to start the device while pressing the detected person, thereby starting the The heart rate sensor 131 works; or, when the heart rate detection module 13 moves upward and shrinks into the bottom shell 12 to leave the detected person, the heart rate sensor activation device is turned off, thereby turning off the heart rate sensor 131 to work.

In this embodiment, the heart rate detection module driving device 14 is preferably transformed into the up and down movement of the heart rate detection module 13 through rotational motion. 3 and 4, the heart rate detection module drive device 14 includes a screw 141, a nut 142 (specifically, a hot-melt copper nut) and a drive switch 143, the nut 142 is arranged on the heart rate detection module 13, the The screw 141 passes through the nut 142 and forms a screw pair with the nut 142 . Specifically, the outer surface of the screw 141 and the inner surface of the nut 142 are provided with matching threads. The driving switch drives 143 the screw 141 to rotate, and the heart rate detection module 13 moves up and down under the screwing action of the screw 141 and the nut 142 by the principle of screwing. It can be seen that the heart rate detection module driving device 14 in this embodiment converts the rotation movement of the screw rod 141 and the nut 142 into the up and down movement of the heart rate detection module.

In one embodiment, the driving switch 143 is a rotating wheel, and the rotating wheel is tightly sleeved on the screw rod 141 . The face shell 11 is provided with an opening 119 ( FIG. 2 ) to protrude part of the runner. In this way, by turning the wheel clockwise/counterclockwise, the operator can drive the screw 141 to rotate clockwise/counterclockwise, thereby driving the heart rate detection module 13 to move up/down.

In this way, the heart rate detection module 13 moves under the action of the heart rate detection module driving device 14. Due to the two ribs 122, the heart rate detection module 13 only has two degrees of freedom of up and down movement. , due to the principle of threaded screwing, it can move up and down.

In a preferred embodiment, the heart rate sensor activation device is a pressure sensor, and the pressure sensor is placed on the heart rate detection module and connected to the heart rate sensor. When the heart rate detection module 13 moves down and compresses the person to be detected, and the pressure sensor is subjected to an external pressure greater than or equal to a preset value, the heart rate sensor is started to measure; and/or the heart rate detection module 13 When moving upward and away from the subject, when the external pressure on the pressure sensor is less than the preset value, the heart rate sensor is turned off to stop the measurement.
