A piezoelectric thin film sensor is installed below the head and neck area, and soft filling is provided around the piezoelectric thin film sensor. A lower pillow is provided below both the low pillow section and the high pillow section. This heart rate acquisition device, through the pillow body and the piezoelectric thin film sensor, realizes the acquisition of the human heart rate by installing the piezoelectric thin film sensor in the pillow without direct contact with the human body. The shape of the pillow body is relatively special, with low and high pillow sections, which meets the needs of people with different usage habits, thus increasing the flexibility of the pillow body in use."

[0004] When using the above technology, the following technical problems were found in the existing technology: the above device is limited to static use. With the improvement of living standards, people pay more attention to health and generally exercise their bodies through exercise. Heart rate is the core indicator for measuring exercise intensity and ensuring exercise safety. The above device cannot meet the needs of exercise monitoring and is difficult to adapt to changes in human posture during exercise. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the above-mentioned device is limited to static use. With the improvement of living standards, people pay more attention to health and generally exercise their bodies through sports. Heart rate is the core indicator for measuring exercise intensity and ensuring exercise safety. The above-mentioned device cannot meet the needs of exercise monitoring and is difficult to adapt to changes in human posture during exercise.

[0006] The heart rate acquisition device adapted for chest straps and wrist straps described in this utility model includes a heart rate acquisition device body; a base is installed at the bottom of the heart rate acquisition device body; a disassembly component is provided on the outside of the base; binding straps are provided on both sides of the outside of the base; the binding straps are connected to the base through the disassembly component; a acquisition component is provided at the bottom outside of the base; and a sweat-wicking component is provided at the bottom outside of the base.

[0007] The disassembly assembly includes a mounting slot; the mounting slot is located on both sides of the outer side of the base, and a mounting block is provided inside the mounting slot; multiple sets of limiting holes are provided inside the mounting block; a telescopic rod is slidably connected to the top of the inner side of the mounting slot; a movable plate is fixedly connected to the outer side of the telescopic rod; the movable plate slides inside the base; a screw is rotatably connected to the inside of the base near the movable plate; the screw is threadedly connected to the movable plate; an internal hexagon screw is fixedly connected to one end of the screw near the outer side of the base; a return spring is installed on the outer side of the internal hexagon screw; the other end of the return spring is fixedly connected to the base; a guide angle is provided at one end of the telescopic rod.

[0008] The acquisition component includes a buffer groove; the buffer groove is located at the bottom outer side of the base; a buffer spring is installed inside the buffer groove; an electrode plate is installed at the end of the buffer spring; the electrode plate slides inside the buffer groove; a wire is installed inside the buffer groove; one end of the wire is connected to the electrode plate.

[0009] The sweat-wicking component includes an isolation pad; the isolation pad is located at the bottom outer side of the base; multiple sets of sweat-wicking grooves are formed on the outer side of the isolation pad.

[0010] A sweat-absorbing layer is fixed to the inside of the restraint strap; a protective layer is installed on the side of the sweat-absorbing layer away from the restraint strap.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example

[0026] like Figure 1 - Figure 6As shown, a heart rate acquisition device adapted for chest straps and wrist straps includes a heart rate acquisition device body 1; a base 12 is mounted on the bottom of the heart rate acquisition device body 1; a disassembly assembly is provided on the outer side of the base 12; restraint straps 11 are provided on both outer sides of the base 12; the restraint straps 11 are connected to the base 12 through the disassembly assembly; a acquisition assembly is provided on the bottom outer side of the base 12; a sweat-wicking assembly is provided on the bottom outer side of the base 12; the disassembly assembly includes an installation groove 2; the installation groove 2 is located on both outer sides of the base 12, and an installation block 21 is provided inside the installation groove 2; multiple sets of limiting holes 22 are provided inside the installation block 21; a telescopic rod 23 is slidably connected to the top inner side of the installation groove 2; a moving plate 25 is fixedly connected to the outer side of the telescopic rod 23; the moving plate 25 slides inside the base 12; a screw 26 is rotatably connected to the inside of the base 12 near the moving plate 25; the screw 26 is threadedly connected to the moving plate 25; the screw 26 is close to the moving plate 25. A hexagonal screw 27 is fixed to one end near the outer side of the base 12; a return spring 28 is installed on the outer side of the hexagonal screw 27; a guide angle 24 is provided at one end of the telescopic rod 23; the acquisition component includes a buffer groove 3; the buffer groove 3 is located at the bottom outer side of the base 12; a buffer spring 31 is installed inside the buffer groove 3; an electrode 33 is installed at the end of the buffer spring 31; the electrode 33 slides inside the buffer groove 3; a wire 32 is installed inside the buffer groove 3; one end of the wire 32 is connected to the electrode 33, allowing the electrode 33 to make slight displacement within the buffer groove 3, making the skin fit the electrode 33 more comfortably when the user wears the heart rate acquisition device body 1, reducing the long-term pressure of the electrode 33 on the skin and the occurrence of pressure marks during long-term wear; the sweat-wicking component includes an isolation pad 4; the isolation pad 4 is located at the bottom outer side of the base 12; multiple sets of sweat-wicking grooves 41 are provided on the outer side of the isolation pad 4.

[0027] During operation, depending on the user's need to wear the heart rate acquisition device 1 on their wrist or chest, different lengths of restraint straps 11 are selected. Then, the mounting block 21 connected to the restraint strap 11 is inserted into the mounting groove 2 inside the base 12. At this time, the guide angle 24 is squeezed by the mounting block 21, causing the telescopic rod 23 to begin to retract. When the mounting block 21 is fully inserted into the mounting groove 2, the limiting hole 22 is located at the bottom of the telescopic rod 23. At this time, the telescopic rod 23 resets and enters the limiting hole 22 to fix it. Then, the isolation pad 4 is attached to the side of the base 12 away from the heart rate acquisition device 1, so that it is in contact with the skin. The device is applied to the skin and then worn on the main body 1 of the heart rate acquisition device. The electrode pads 33 slide within the buffer groove 3 due to skin pressure, while the buffer spring 31 supports the buffer groove 3 to prevent it from detaching from the skin. The data collected by the electrode pads 33 is transmitted to the main body 1 of the heart rate acquisition device via the wire 32 for processing. During strenuous activity, the user's skin secretes a large amount of sweat. Prolonged contact between sweat and the electrode pads 33 may affect the accuracy of data acquisition, accelerate the aging of the electrode pads 33, and reduce their lifespan. Therefore, the sweat-draining groove 41 is used to guide the sweat, reducing the long-term retention of sweat on the electrode pads 33. 3. The surface of the electrode 33 affects its service life. After the user finishes exercising, the surface of the device is often soaked with sweat. However, the cleaning methods between the restraint strap 11 and the main body 1 of the heart rate acquisition device are different. At this time, rotating the hexagonal screw 27 will drive the screw 26 to start rotating. Since one end of the return spring 28 is fixed to the hexagonal screw 27 and the other end is fixed to the base 12, the return spring 28 will deform when the hexagonal screw 27 is rotated. This will cause the moving plate 25 to drive the telescopic rod 23 to move upward, thus removing the limitation of the telescopic rod 23 on the mounting block 21 inside the limiting hole 22. At this time, the mounting block 21 and the base 1 can be connected. 2. Separate the components. Loosen the hex screw 27, and the return spring 28 will begin to reset, resetting the moving plate 25 and the telescopic rod 23. Then, clean and store the heart rate acquisition device body 1 and the restraint strap 11 separately to reduce the contamination of the device by sweat. By using the restraint strap 11 and the disassembly components, the heart rate acquisition device body 1 can be worn on the user's wrist or chest during exercise by changing the length of the restraint strap 11, increasing the flexibility of the device during operation and making it more suitable for changes in the posture of the human body during exercise. At the same time, it can also effectively monitor the strength of the heart rate, increasing the practicality of the device. Example

[0028] like Figure 1 As shown, a sweat-absorbing layer 5 is fixed to the inner side of the binding strap 11; a protective layer 51 is installed on the side of the sweat-absorbing layer 5 away from the binding strap 11. The protective layer 51 is woven from 85% polyester fiber and 15% spandex, which has the function of reducing friction and enhancing elasticity.

[0029] During operation, the sweat-absorbing layer 5 and the protective layer 51 are installed on the inside of the restraint strap 11. During the wearing process, the restraint strap 11 will be subjected to strong pressure due to the wearer's vigorous exercise. At the same time, this pressure will react at the contact point with the skin. Therefore, the protective layer 51 reduces the friction between the restraint strap 11 and the skin, thus protecting the skin. Meanwhile, the sweat-absorbing layer 5 absorbs the sweat generated during exercise, reducing the impact of sweat on the wearing experience.
