Description

Technical Field

[0001] The present invention relates to the technical field of heart rate monitors, and specifically to a heart rate monitor for sports and health management. Background Art

[0002] With the continuous improvement of people's attention to health, physical exercise has become one of the important ways to maintain good health. During physical exercise, it is crucial to understand one's own physical condition. Heart rate is one of the important indicators reflecting the intensity of physical activity and health status. Traditional heart rate monitoring methods mainly include manually feeling the pulse and using electrocardiogram equipment, etc. However, these methods have some limitations. Manually feeling the pulse is not accurate enough and it is difficult to continuously monitor during exercise. Although electrocardiogram equipment is accurate, it is usually large in size and complex in operation, and is not suitable for use in daily physical exercise. Generally speaking, the development of heart rate monitors for sports and health management provides people with more convenient and accurate heart rate monitoring means, which helps people better understand their physical conditions and formulate scientific and reasonable exercise plans. For example, the patent with publication number CN109875530B discloses a digital medical health parameter monitoring device. The present invention adopts the synchronous monitoring method of a main photoelectric heart rate monitor and a secondary photoelectric heart rate monitor, which can greatly improve the monitoring efficiency. Moreover, the monitoring method is simple and convenient, which can greatly improve the monitoring efficiency. Light-shielding baffles are arranged on the outer sides of the main monitoring seat and the secondary monitoring seat of the present invention. The main photoelectric heart rate monitor and the secondary photoelectric heart rate monitor are both located inside the light-shielding baffles. In this way, the influence of external light on the monitor can be reduced and the monitoring accuracy can be improved. An adjusting component is also arranged between the main monitoring seats at both ends of the fixed seat of the present invention, which can conveniently and automatically clamp and position the patient's arm to achieve the purpose of rapid and automatic monitoring.

The right one-gear 221 is fixedly arranged at the right end of the main rotating roller 212 and rotates synchronously. By rotating the main rotating roller 212, the right one-gear 221 meshes with the right two-gear 222 and the right three-gear 224 in sequence to drive the generator 227 to work, and then store the electricity in the power storage box 228. Through this design, it is beneficial to save power consumption and reduce the use cost.

[0035] As a further aspect of the present invention, the transmission assembly 23 includes a first left gear 231 and a second left gear 232. The first left gear 231 is installed at the left end of the secondary rotating roller 213. The bottom end of the first left gear 231 meshes with and drives the second left gear 232. The second left gear 232 is fixedly arranged at the center of the third drive shaft 233. The rear end of the second left gear 232 drives the third left gear 234 to rotate. The third left gear 234 is installed at the right end of the fourth drive shaft 235. The left end of the fourth drive shaft 235 is installed at the bottom end of the second belt group 6. By the rotation of the secondary rotating roller 213, the first left gear 231 in the transmission assembly 23 can be driven to sequentially mesh with the second left gear 231 and the third left gear 234, thereby driving the second belt group 6 to drive the protective mechanism 5 at the top to work. Through this design, it is beneficial to better improve the applicability, facilitate people to quickly open the protective mechanism 5 to take out the monitoring bracelet 34 for wearing, and thus facilitate the subsequent heart rate monitoring.

[0036] As a further aspect of the present invention, a connector 32 is installed at the left end of the monitor 31. A transmission line 33 is provided at the front end of the connector 32.

Through this design, it is beneficial for the monitoring bracelet to more quickly, conveniently and stably transmit the monitoring data to the monitor in real time, so that the user can see it during exercise. Accurate heart rate monitoring means help people better understand their physical conditions and formulate scientific and reasonable exercise plans.

[0037] As a further aspect of the present invention, second guide rails 511 are fixedly arranged on both inner walls of the placement box 51. The front end of the switch assembly 52 is connected inside the two groups of second guide rails 511. The switch assembly 52 includes a rack plate 521 and a trapezoidal slider 522. Trapezoidal sliders 522 are fixedly arranged on both walls of the rack plate 521. The trapezoidal sliders 522 are respectively sleeved inside the second guide rails 511. The bottom side of the rear end of the rack plate 521 meshes with the top end of the limit gear 523. The limit gear 523 is fixedly arranged at the center of the fifth drive shaft 524. The fifth drive shaft 524 is inserted into the top left wall of the moving frame 1. The left end of the fifth drive shaft 524 is connected to the top end of the second belt group 6. Through the two groups of second guide rails 511 installed inside the placement box 51, the trapezoidal sliders 522 installed on both walls of the rack plate 521 can be limited to move. Through this design, it is beneficial for the rack plate 521 to move smoothly under the meshing of the limit gear 523. The switch assembly 52 can protect the monitoring bracelet 34 when not in use, thereby improving the service life of the detection bracelet and reducing cost consumption.

[0038] Working principle: During operation, when it is necessary to monitor the heart rate of the monitored person during exercise, the monitored person only needs to stand on the sports mechanism 2 tilted at a certain angle, and then use one foot to step on the auxiliary rotating roller 212 at the rear end, and then step on the front end to facilitate the rotation of the auxiliary rotating roller 213, and the rubber strip 2124 bonded around the side of the sleeve 2123 can increase the friction and facilitate rotation. The rotation of the auxiliary rotating roller 213 can drive the left first gear 231 fixed at the left end to rotate synchronously, and the rotation of the left first gear 231 can mesh with the left second gear 232 at the bottom to rotate, and the left second gear 232 can rotate at the center of the third driving shaft 233, and the rotation of the left second gear 232 also meshes with the left third gear 234 to rotate, and the rotation of the left third gear 234 can drive the left first gear 231 fixed at the left end to rotate synchronously. The fourth drive shaft 235 at the bottom left end of the frame (1) rotates, and the fourth drive shaft 235 rotates to drive the second belt group 6 installed at the left end to rotate. Under the drive of the fourth drive shaft 235, the second belt group 6 can drive the fifth drive shaft 524 connected to the top to rotate. The rotation of the fifth drive shaft 524 can drive the limit gear 523 fixed in the center to rotate. The limit gear 523 rotates to engage the rack plate 521 at the top to move backward. The trapezoidal slider 522 fixed on the two walls of the front end of the rack plate 521 can slide in the second guide rail 511 installed at the top of the placement box 51. When the rack plate 521 moves to the rear end until the monitoring bracelet 34 is exposed, the auxiliary rotating roller 213 can be stopped from being rotated with the foot, and the monitor can take out the monitoring bracelet 34 and wear it on the arm.

[0039] When it is necessary to monitor the heart rate during exercise, the user can hold the two sides of the exercise frame 1 with his hands and then run with his feet on the eight sets of secondary rotating rollers 214 and the main rotating roller 212 installed in the center to rotate. When the main rotating roller 212 rotates during running, it can drive the first right gear 221 installed at the right end to rotate. The first right gear 221 rotates to mesh with the second right gear 222 at the bottom to rotate. The second right gear 222 rotates to synchronously mesh with the third right gear 224 at the rear end to rotate. The third right gear 224 rotates to drive the second drive shaft 225 fixed at the bottom of the exercise frame 1 to rotate. The second drive shaft 225 rotates to rotate. The first belt group 226 fixed through the center rotates and then drives the generator 227 connected to the rear end to rotate and generate electricity. The electric energy generated by the generator 227 can be transmitted to the power storage box 228 connected to the left end. The internal electric energy of the power storage box 228 can be transmitted to the top monitor 31 through the connecting line 4 to power it. During exercise, the monitoring bracelet 34 can display the monitored heart rate on the monitor 31 in real time under the transmission line 33 and the connector 32. When the monitor finishes monitoring the heart rate, the monitoring bracelet 34 is placed back in the placement box 51 and the auxiliary rotating roller 213 is stepped on in the reverse direction to be protected by the rack plate 521.
