[0029] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a high-precision heart rate detector for sports training, comprising...
[0030] The heart rate detection mechanism 100 includes a first photoelectric sensor 110 and a second photoelectric sensor 120; a mounting transmission frame 200 includes a transmission frame 210, which includes an upper side plate 211. One end of the upper side plate 211 is hinged to a lower side plate 213, and a base 215 is fixedly mounted on the bottom of the lower side plate 213; a hinge assembly 220 is mounted on one end of the transmission frame 210, and the hinge assembly 220 is drivenly connected to one end of the transmission frame 210; an auxiliary locking assembly 230 is drivenly mounted on the other end of the transmission frame 210, and the auxiliary locking assembly 230 is limited and locked to the transmission frame 210. By using the first photoelectric sensor 110 and the second photoelectric sensor 120, the dual sensors detect pulse signals from different positions above and below the wrist, which can more comprehensively and accurately capture pulse signals, effectively improve the accuracy of heart rate detection, and provide reliable data support for sports training.
[0031] Please see Figure 3 and Figure 4The transmission frame 210 also includes an upper connecting plate 212 and a lower connecting plate 214. The upper connecting plate 212 is arc-shaped, and the inner walls of the upper side plate 211 are fixedly installed on both sides of the upper connecting plate 212. The lower connecting plate 214 is arc-shaped, and the inner walls of the lower side plate 213 are fixedly installed on both sides of the lower connecting plate 214. The internal shapes of the upper side plate 211 and the lower side plate 213 are adapted to the wrist. The base 215 is an isosceles trapezoid, and both sides of the base 215 are fixedly connected to the lower side plate 213. The bottom inner part of the base 215 has a mounting hole. The isosceles trapezoidal shape of the base 215 increases the bearing area and facilitates installation.
[0032] The base 215 is equipped with a battery or a first photoelectric sensor 110 and a second photoelectric sensor 120 that are connected to an external power source. Meanwhile, a screen is provided on the outside of the base 215 to display the heart rate measured by the first photoelectric sensor 110 and the second photoelectric sensor 120 respectively, so as to avoid inaccurate measurement due to damage to one of them.
[0033] The hinge assembly 220 includes a first fixed plate 221, with both ends of the first fixed plate 221 fixedly installed between two lower side plates 213. A first transmission rod 223 is threaded through the middle of the first fixed plate 221. A transmission block 222 is rotatably mounted above the first transmission rod 223. The first fixed plate 221 is rotatably mounted on both sides of the transmission block 222. A first handle 224 is fixedly installed at the bottom of the first transmission rod 223. The first handle 224 is easy to screw on. By adjusting the first handle 224, the transmission block 222 can be moved up and down, which can be adjusted to prevent lower grade students from using it while higher grade students cannot.
[0034] A connecting rod 216 is driven through one end of the upper side plate 211, and a transmission hole 217 is opened at each of the two ends of the lower side plate 213. The two ends of the connecting rod 216 are vertically slidably installed in the transmission hole 217. The middle part of the transmission block 222 is rotatably sleeved on the connecting rod 216 and located in the middle of the upper side plate 211. The first transmission rod 223 is adjusted to drive the upper and lower connecting rods 216, thereby changing the height of one end of the upper side plate 211. At the same time, the upper side plate 211 is located between the two lower side plates 213.
[0035] The auxiliary locking assembly 230 includes a second fixing plate 231, which is fixedly installed in the middle of the other end of the lower side plate 213 and located below another transmission hole 217. A second transmission rod 232 is threaded through the middle of the second fixing plate 231. A transmission seat 234 is rotatably connected to the top of the second transmission rod 232. A slide rod 237 is rotatably installed through the middle of the transmission seat 234. The two ends of the slide rod 237 are vertically slidably installed in the transmission hole 217. A second handle 233 is fixedly connected to the bottom of the second transmission rod 232. By turning the second transmission rod 232, the transmission seat 234 is moved up and down to lock the limit block 219.
[0036] A hinge ring 235 is rotatably sleeved at the middle of the slide rod 237. A screw 236 is fixedly connected to one side of the hinge ring 235. A limit block 219 is connected to the other end of the upper side plate 211. The screw 236 is locked in place with the limit block 219. The screw 236 is L-shaped, and the limit block 219 is rectangular. A strip-shaped through hole is opened on the side of the limit block 219 near the screw 236. Positioning rods 218 are fixedly connected to both sides of the limit block 219. The positioning rods 218 are fixedly connected to the inner wall of the upper side plate 211.
[0037] A limiting block 238 is sleeved on the top of the screw 236. One end of the limiting block 238 corresponds to the limiting block 219. A nut 239 is threaded onto the top of the screw 236. A spring is installed at the bottom of the nut 239 to limit rotation. The spring is embedded in the inner bottom of the limiting block 238. The corners where the limiting block 238 and the limiting block 219 contact each other are rounded. The arc shape facilitates the locking of the limiting block 238 onto the top of the limiting block 219.
[0038] Working principle: Preparation stage: The device is fixed in a suitable location next to the gymnasium or playground through the mounting holes of the base 215. The upper side plate 211 and the lower side plate 213 are in a movable state, and the first photoelectric sensor 110 and the second photoelectric sensor 120 are in a standby state.
[0039] Wrist placement: After exercise, the student places their wrist above the lower side plate 213, at which point the second photoelectric sensor 120 is aligned with the wrist pulse position.
[0040] Closure: The student flips the upper side plate 211 so that it rotates around the hinge with the lower side plate 213 until the first photoelectric sensor 110 inside the upper side plate 211 is facing the upper part of the student's wrist.
[0041] Locking device: Place the screw 236 into the slotted through hole (groove) in the limiting block 219. Tighten the second transmission rod 232. Since the second transmission rod 232 is threaded through the second fixing plate 231, the rotation of the second transmission rod 232 will cause the transmission seat 234 at its top to move up or down. A sliding rod 237 is rotatably installed in the middle of the transmission seat 234. The two ends of the sliding rod 237 are vertically slidably installed in the transmission hole 217 at the end of the lower side plate 213. Therefore, the movement of the transmission seat 234 will drive the sliding rod 237 to move. A hinge ring 235 is rotatably sleeved in the middle of the sliding rod 237. The screw 236 on one side of the hinge ring 235 will also move accordingly. As the screw 236 moves, the limiting block 238 descends and cooperates with the limiting block 219 to tighten the upper side plate 211, firmly fixing the device on the student's wrist.
[0042] Heart rate detection: The first photoelectric sensor 110 and the second photoelectric sensor 120 emit light of a specific wavelength to illuminate the blood vessels under the skin of the wrist. By detecting changes in the intensity of the reflected light, signals related to the pulse are obtained. These signals are processed to obtain the student's heart rate data.
[0043] Release the fixation: After the test is completed, rotate the second transmission rod 232 in the opposite direction to raise the limit block 238, releasing the tension on the upper side plate 211. The student removes their wrist from the device, and the device returns to its initial state, ready for the next student to use.
[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
