Description

Technical Field

[0001] The utility model relates to the technical field of heart rate monitoring, in particular to a wristband type UWB heart rate monitoring positioning card. Background Art

[0002] UWB heart rate monitoring is a contactless monitoring system based on IR-UWB radar, which can track the human heart rate and breathing rate in real time. The general specific products include watch-shaped instruments. Users can monitor the body's heart rate and other physical conditions in real time by wearing it on their wrists. However, during use, some users may suffer from hand injuries or hand disabilities, which makes it inconvenient for users of general watch straps to wear it. Although the existing magnetic watch straps are easy for users to wear, users still need to use their hands to adjust the tightness of the watch straps, which is inconvenient. In addition, when the magnetic watch strap is used for exercise and other behaviors, the hand will produce a large swing. Since the two straps of the magnetic watch strap mainly rely on magnetism to attract each other and remain fixed, the fixing effect is poor. When encountering a large swing, the surfaces of the straps may slide against each other, causing the inner diameter of the ring formed by the two straps to expand, or the two straps are directly thrown apart, which is inconvenient.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 In an embodiment of the utility model, a wristband type UWB heart rate monitoring positioning card includes an instrument body 100, one end of the instrument body 100 is fixedly connected to a first strap 110, and the other end of the instrument body 100 is fixedly connected to a second strap 120, and a fixing mechanism 400 is provided between the first strap 110 and the second strap 120;

[0022] The fixing mechanism 400 includes a box body 410, and one end of the second strap 120 is fixedly connected to one side of the box body 410, a rectangular through hole 411 is opened on one side of the box body 410, and one end of the first strap 110 passes through the inside of the rectangular through hole 411, a guide hole 412 is opened on the bottom surface of the box body 410, and the inside of the guide hole 412 is connected to the inside of the rectangular through hole 411, a pressure plate 430 is arranged inside the rectangular through hole 411, and a plurality of rebound springs 431 are fixedly connected between the top surface of the pressure plate 430 and the top surface of the rectangular through hole 411, slide plates 440 are fixedly connected to both ends of the bottom surface of the pressure plate 430, and the outer walls of the two slide plates 440 are respectively slidably engaged with the two ends of the inside of the guide hole 412, and a roller 441 is rotatably connected between the two slide plates 440.

[0023] Specifically, in the initial state, the pressure plate 430 is driven by the adjacent rebound spring 431 to press the first strap 110 on the inner bottom surface of the box body 410. At this time, the roller 441 does not contact the first strap 110. Then the user can pass the hand through the ring body formed by the first strap 110 and the second strap 120. Then, if the user's hand is inconvenient to use, the user can press the hand wearing the instrument body 100 to a flat surface such as a desktop, so that the roller 441 contacts the desktop, and the box body 410 is pressed on the wrist and is not easy to move. The pressure plate 430 is driven by the roller 441 to move upward, so that the roller 441 contacts the first strap 110. The user can then move his wrist to make the roller 441 roll and rub the first strap 110 at the same time, thereby reducing the inner diameter of the ring formed by the first strap 110 and the second strap 120, making it easier for the user to wear it with one hand. The user can then lift his wrist to allow the pressure plate 430 to press the first strap 110 again due to the rebound spring 431 to fix it. When the user needs to remove the instrument body 100 from the wrist, the user can press the roller 441 on the table and roll it to make the first strap 110 be rubbed by the roller 441, thereby expanding the inner diameter of the ring formed by the first strap 110 and the second strap 120, and then the user takes his hand out.

[0024] Embodiment 1

[0025] like Figure 1-4 As shown, in this embodiment, the outer wall of the roller 441 is fixedly connected with a plurality of convex strips 442 , and a plurality of grooves 111 are opened on one side of the first strap 110 , and the convex strips 442 are movably engaged in the grooves 111 .

[0026] In this embodiment, when the roller 441 contacts the first strap 110, the convex strip 442 on the roller 441 can be stuck in the adjacent groove 111 when the roller 441 rolls on the desktop to drive the first strap 110 to move, so that the first strap 110 is more stable when being moved by the roller 441. The convex strip 442 is made of rubber material to increase the friction with the desktop.

[0027] like Figure 4 As shown, in this embodiment, a plurality of spike blocks 432 are fixedly connected to the bottom surface of the pressing plate 430, U-shaped plates 450 are fixedly connected to both ends of the bottom surface of the box body 410, and a rotating cylinder 451 is rotatably connected between the two arms of the two U-shaped plates 450.

[0028] In a specific implementation, when the pressure plate 430 is driven by the rebound spring 431 to press the first strap 110 onto the inner bottom surface of the box body 410, a plurality of spike blocks 432 can press the first strap 110 into a depression, thereby improving the fixing effect of the pressure plate 430 on the first strap 110. The first strap 110 can be made of rubber material, and the sharp end of the spike block 432 is relatively blunt and will not penetrate into the inside of the first strap 110. When the roller 441 rolls on the desktop, the roller 441 and any rotating drum 451 are in contact with the desktop, so that the rotating drum 451 supports the roller 441, making it convenient for the user to roll the roller 441.

[0029] like Figure 2 As shown, in this embodiment, a cutting groove 121 is opened on one side of the second strap 120, and a metal strap 200 is fixedly connected inside the cutting groove 121, and a magnetic patch 210 is fixedly connected to one end of the other side of the first strap 110.

[0030] In a specific implementation, after the user wears the instrument body 100 on the wrist, the metal band 200 is woven with iron wires, and the first strap 110 can be adsorbed onto the metal band 200 through the magnetic patch 210 to fix the first strap 110 to the second strap 120 .

[0031] Embodiment 2

[0032] On the basis of the first embodiment, in order to compensate for the first strap 110 being separated from the rectangular through hole 411 in the first embodiment, a limiting plate 300 is provided to prevent the first strap 110 from being separated from the rectangular through hole 411 .

[0033] like Figure 1-4 As shown, in this embodiment, one end of the first strap 110 is fixedly connected to the limiting plate 300, and the length and width of one side of the limiting plate 300 are greater than the length and width of the rectangular through hole 411, and a plurality of card slots 201 are provided on one side of the second strap 120 and the metal strap 200, and a card strip 220 is fixedly connected to one side of the limiting plate 300, and the card strip 220 is movably connected to the inside of the adjacent card slot 201, and a rubber pad 420 is fixedly connected to the top surface of the box body 410.

[0034] In specific implementation, the limiting plate 300 is used to prevent one end of the first strap 110 from being easily detached from the rectangular through hole 411, and after the magnetic patch 210 is adsorbed onto the metal strap 200, the user can press the wrist against the table and press the card strip 220 into the adjacent card slot 201, thereby further improving the fixing effect between the first strap 110 and the second strap 120. When the user presses the roller 441 on the table, the box body 410 is pressed against the wrist, and the friction between the box body 410 and the skin is increased by the rubber pad 420 to prevent the box body 410 from sliding on the wrist.
