Description

Technical Field

[0001] The utility model relates to the technical field of human vital sign monitoring, in particular to a non-contact heart rate monitoring device. Background Art

[0002] Most of the vital sign monitoring devices on the market are wearable at present. Therefore, when resting at night, in order to ensure the comfort during sleep, users generally take off the wearable device. Then, during this process, the breathing and heart rate indicators of the users cannot be monitored. Once an emergency occurs at night and cannot be detected by people around in time, serious consequences may be caused.

[0003] Therefore, a prior art non-contact breathing and heart rate monitoring device, with the publication number: CN213721932U, includes a controller and a first radio frequency transceiver and a second radio frequency transceiver connected to the controller. The first radio frequency transceiver and the second radio frequency transceiver are respectively used to monitor the frequency signals of breathing and heart rate when a person lies on the side and lies flat. The first radio frequency transceiver is arranged in the vertical direction and the second radio frequency transceiver is arranged in the horizontal direction, and the second radio frequency transceiver is hinged to the upper end of the first radio frequency transceiver so that the second radio frequency transceiver can rotate to adjust the angle of the second radio frequency transceiver.

[0004] This device is used to monitor a person's vital signs when the person is sleeping. When a person is sleeping, due to the lack of self-awareness, they often unconsciously adjust their sleeping posture. When the adjustment range is relatively large, they may get out of the monitoring range of this device, making this device ineffective. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems existing in the prior art, and a non-contact heart rate monitoring device is proposed.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A non-contact heart rate monitoring device includes a heart rate monitor, and also includes an electric telescopic rod. The telescopic end of the electric telescopic rod is fixedly connected with a housing. The inner top surface of the housing is rotatably connected with a number of synchronously rotating gears, and a rack meshingly connected with the gears is inserted and embedded in the inner side wall of the housing. The tooth back surface of the rack is located outside the housing, and a rotating frame is rotatably connected to one side of the tooth back surface. An arc-shaped frame is rotatably connected to one side of the rotating frame. A chute is opened on the inner arc surface of the arc-shaped frame, and motion cameras are installed at both ends of the inner arc surface of the arc-shaped frame. The heart rate monitor is slidably installed in the chute, and the heart rate monitor is externally connected with a display screen and a keyboard circuit.

[0007] Preferably, the other end of the rotating frame is fixedly connected with a pin shaft penetrating through the tooth back of the rack, and motors for driving one of the gears and the pin shaft to rotate are respectively fixedly connected to the housing and the rack.

[0008] Preferably, a gear is also rotatably connected to the side surface of the heart rate monitor, an arc-shaped rack two is fixedly connected in the chute, and the arc-shaped rack two is meshed with the gear on the heart rate monitor.

[0009] Preferably, arc-shaped racks one are fixedly connected to the two motion cameras and are in embedded sliding connection with the outer arc surface of the arc-shaped frame. The tooth surfaces of the two arc-shaped racks one face each other and are staggeredly distributed. A bevel gear meshed with the opposite tooth surfaces of the two arc-shaped racks one is rotatably connected to the outer arc top of the arc-shaped frame. Motors are installed on the side surface and the outer arc top of the arc-shaped frame. The motor at the outer arc top is fixed on the arc-shaped frame and its main shaft is fixed to the bevel gear. The motor on the side is in embedded sliding connection with the side of the arc-shaped frame and its main shaft is fixed to the end face of the gear on the heart rate monitor.

[0010] Preferably, an electric push rod is rotatably connected between the rotating frame and the arc-shaped frame.

[0011] Preferably, the signal output end of the keyboard circuit is connected to the display screen through a processor. The processor is provided with another signal input end and is connected to the millimeter-wave radar module.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0013] 1. In the present utility model, the position and sleeping posture of a person are monitored by setting up motion cameras. Once it is found that the sleeping posture of the person has changed, a signal is transmitted via the motion cameras to control the electric push rod to start, and the arc-shaped frame is pushed to swing to achieve the effect of position adjustment. When the person sleeps on the side or turns over, a signal is transmitted via the motion cameras to control the sliding heart rate monitor, so that the heart rate monitor is always aligned with the person's chest in real time to monitor the person's vital signs.

[0014] 2. In the present utility model, when the motion cameras cannot detect the position of the human figure, the motion cameras transmit signals. At this time, the motor and the electric push rod installed on the top of the arc-shaped frame are started. This motor drives the motion cameras to swing through transmission, and the electric push rod expands and contracts to drive the arc-shaped frame to swing, thereby expanding the monitoring range of the motion cameras and helping the motion cameras to better find the human figure.

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] As Figures 1-5 shown, a non-contact heart rate monitoring device includes a heart rate monitor 12, and also includes an electric telescopic rod 1. The telescopic end of the electric telescopic rod 1 is fixedly connected to a housing 2. A plurality of synchronously rotating gears 4 are rotatably connected to the inner top surface of the housing 2, and a rack 5 meshing with the gears 4 is inserted and connected to the inner side wall of the housing 2. The tooth back surface of the rack 5 is located outside the housing 2, and a rotating frame 7 is rotatably connected to one side of the tooth back surface. One end of the rotation point of the rotating frame 7 is fixedly connected to a pin shaft 10 passing through the tooth back of the rack 5. Motors 3 for driving one of the gears 4 and the pin shaft 10 to rotate are fixedly connected to the housing 2 and the rack 5 respectively.

[0024] With this technical solution, by adjusting the position of the rack 5, the position of the rotating frame 7 can be changed, enabling the rotating frame 7 to perform steering adjustment above the sleeping position of a person. Furthermore, the heart rate monitor 12 installed on the arc-shaped frame 11 can be adjusted in position to align with the chest position of the person. Specifically, the electric telescopic rod 1 is adjusted in height. After adjusting to a suitable height, the motor 3 installed on the housing 2 is started. The motor 3 drives the gear 4 to rotate. The rotation of the gear 4 drives the rack 5 to move. The movement of the rack 5 drives the rotating frame 7 to move. Then, the motor 3 used to control the rotation of the rotating frame 7 is started. The motor 3 drives the rotating frame 7 to rotate to further adjust the position of the arc-shaped frame 11, so that the heart rate monitor 12 installed on the arc-shaped frame 11 aligns with the chest position of the person. Further, the several gears 4 located inside the housing 2 are driven by a belt.

[0025] As Figures 3-5 shown, one side of the rotating frame 7 is rotatably connected to an arc-shaped frame 11. A chute 16 is formed on the inner arc surface of the arc-shaped frame 11, and motion cameras 15 are installed at both ends of the inner arc surface of the arc-shaped frame 11. A gear 4 is also rotatably connected to the side surface of the heart rate monitor 12. An arc-shaped rack one 14 is fixedly connected inside the chute 16, and the arc-shaped rack one 14 is meshed with the gear 4 on the heart rate monitor 12. Arc-shaped racks two 8 fixedly connected to the two motion cameras 15 are inlaid and slidably connected to the outer arc surface of the arc-shaped frame 11. The tooth surfaces of the two arc-shaped racks two 8 face each other and are staggeredly distributed. A bevel gear 17 meshed with the opposite tooth surfaces of the two arc-shaped racks two 8 is rotatably connected to the outer arc top of the arc-shaped frame 11. Motors 3 are installed on both the side surface and the outer arc top of the arc-shaped frame 11. The motor 3 at the outer arc top is fixed on the arc-shaped frame 11, and its main shaft is fixed to the bevel gear 17. The side motor 3 is inlaid and slidably connected to the side of the arc-shaped frame 11, and its main shaft is fixed to the end face of the gear 4 on the heart rate monitor 12. An electric push rod 9 is rotatably connected between the rotating frame 7 and the arc-shaped frame 11.

[0026] With this technical solution, the motion camera 15 is used to monitor the position and sleeping posture of a person. Once it is detected that the sleeping posture of the person has changed, such as from sleeping straight to sleeping obliquely, it is monitored by the motion camera 15, and a signal is transmitted to the electric push rod 9. The electric push rod 9 will then be activated, and its telescopic end will extend and retract to push the arc-shaped frame 11 to swing to achieve the effect of position adjustment. When the person sleeps on their side or turns over, it is monitored by the motion camera 15, and a signal is transmitted to the motor 3 on the side of the heart rate monitor 12 to make it work, so that the heart rate monitor 12 slides on the arc-shaped frame 11, so that the heart rate monitor 12 is always aligned with the person's chest in real time to monitor the person's vital signs. Specifically, after the rotating frame 7 adjusts its position, the heart rate monitor 12 is facing the person's chest. When the angle of the arc-shaped frame 11 needs to be adjusted, the electric push rod 9 extends and retracts. When the position of the heart rate monitor 12 needs to be adjusted, the motor 3 located on the side of the heart rate monitor 12 is started. The motor 3 drives the gear 4 connected to it to rotate. Because the position of the arc-shaped rack 14 engaged with the gear 4 is fixed, the gear 4 on the side of the heart rate monitor 12 will drive the heart rate monitor 12 to slide in the chute 16 opened on the arc-shaped frame 11. Further, when the motion camera 15 cannot detect the position of the person's image, the motion camera 15 will continue to transmit a signal. At this time, the motor 3 and the electric push rod 9 installed on the top of the arc-shaped frame 11 will be started. This motor 3 drives the bevel gear 17 fixed to its output shaft to rotate. The rotation of the bevel gear 17 drives the two arc-shaped racks 8 to move. The movement of the two arc-shaped racks 8 drives the motion camera 15 to swing, and the electric push rod 9 extends and retracts to drive the arc-shaped frame 11 to swing, so as to expand the monitoring range of the motion camera 15 and help the motion camera 15 better find the person's image.

[0027] As Figure 1 shown, the heart rate monitor 12 is slidably installed in the chute 16. The heart rate monitor 12 is externally connected with a display screen 13 and a keyboard circuit 6. The signal output end of the keyboard circuit 6 is connected to the display screen 13 through a processor. The processor is provided with another signal input end, and the other signal input end is connected to the millimeter wave radar module.

[0028] With this technical solution, the signal input end of the processor and the millimeter wave radar module are connected through an analog-to-digital conversion circuit and a preprocessing circuit. The millimeter wave radar module transmits and receives baseband signals, and by analyzing the frequency differences therein, it realizes the measurement of data such as the heart rate and respiration of the target object. Then, the obtained data is transmitted into the processor through the preprocessing circuit and the analog-to-digital conversion circuit. Through its excellent computing power and processing ability, the incoming data is calculated and predicted, and then the calculated heartbeat signal is displayed through the display screen 13. The keyboard circuit 6 is used to issue work instructions to the processor to make the device applicable to different usage scenarios.

[0029] Working principle: When in use, start the electric telescopic rod 1 to adjust the height. After the height is adjusted to the appropriate position, start the motor 3. The motor 3 drives the gear 4, the pin shaft 10 and the bevel gear 17 to rotate. The gear 4 drives the rack 5 and the arc rack one 14, and the bevel gear 17 drives the arc rack two 8 to move, thereby adjusting the positions of the rotating frame 7, the heart rate monitor 12 and the sports camera 15. After the adjustment is completed, the heart rate monitor 12 is located above the person's chest, and the sports camera 15 is located on both sides of the person. When the person's sleeping position changes, after being monitored by the sports camera 15 and the signal is transmitted, it prompts the motor 3 and the electric push rod 9 to work, and further adjusts the positions of the arc-shaped frame 11 and the heart rate monitor 12, so that the heart rate monitor 12 can monitor the personnel with higher precision.

[0030] The wiring diagrams of the electric telescopic rod 1, the motor 3, the electric push rod 9, the heart rate monitor 12 and the sports camera 15 in the present utility model belong to the common knowledge in the art. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the electric telescopic rod 1, the motor 3, the electric push rod 9, the heart rate monitor 12 and the sports camera 15 will not be explained in detail.

[0031] The above is only the preferred embodiment of the present utility model, and does not limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
