During the process of the test electrodes 6 collecting current signals, the electrode springs 11 provide power to the test electrodes 6. The control module receives the current signals collected by the test electrodes 6, processes them, and identifies the heart rate.

[0035] The heart rate belt also includes a strap 2, which is a long flat structure with retractable ends, and is used to tightly and fixedly connect the host 1 and two test electrodes 6 to the wearer; the host 1 is located in the middle of the length direction of the strap 2 and is fixedly arranged on one side of its thickness direction; a retractable first wire 51 and a second wire 52 are provided at one end of the strap 2, one end of which is respectively connected to the host 1; the two test electrodes 6 are located at both ends of the strap 2 and are fixed on the other side of its thickness direction, and the ends facing one end of the host 1 are respectively connected to the two electrode springs 11.

[0036] The heart rate belt also includes a female connector 3, which is fixedly arranged at one end of the restraint belt 2 and includes an electromagnet 31; the other ends of the first wire 51 and the second wire 52 are respectively connected to the electromagnet 31; through the configuration and operation of the control module, the first wire 51 and the second wire 52 are used to power the electromagnet 31 to generate an electromagnetic field, or the first wire 51 and the second wire 52 are disconnected from powering the electromagnet 31 to stop generating the electromagnetic field.

[0037] The heart rate belt also includes a male head 4, which is made of ferromagnetic material and is installed and adapted to the female head 3. When the user wears the heart rate belt, it is connected to the female head 3 that generates an electromagnetic field to fix the two ends of the restraint belt 2 in connection.

[0038] The heart rate belt of the present invention is provided with an electromagnet 31 on the female head 3 fixed to one end of the restraining belt 2, and the control module controls the way of turning on and off the power of the electromagnet 31, so that the electromagnet 31 generates a magnetic field when the heart rate belt is worn, so that the male head 4 and the female head 3 are fixedly connected by magnetic attraction; when the heart rate belt is disengaged, the electromagnet 31 is controlled to be de-energized, and the electromagnetic field is stopped, so that the male head 4 and the female head 3 are automatically disengaged, which is convenient for wearing and disengaging, and improves the user experience.

[0039] The control module can realize the control of powering on and off of the electromagnet 31 only through a key switch.

[0040] The specific structure and principle of the heart rate monitor of the present invention are described in detail below through specific embodiments.

[0041] In some specific embodiments, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 The electromagnet 31 is horseshoe-shaped, with its opening facing one side in the thickness direction of the strap 2, so that the host 1 faces outward when worn, and the male head 4 is located on the outside of the female head 3 and connected to the position where the magnetic field of the electromagnet 31 is strongest, thereby increasing the stability of the connection.

[0042] In some specific embodiments, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 The female head 3 also includes a receiving member 32, which is a magnetic conductor and is fixedly connected to one end of the restraint belt 2. It has a first connecting plane 323 parallel to the surface of one side of the restraint belt 2, forming a cavity 321 for accommodating the electromagnet 31; the electromagnet 31 is installed in the cavity 321.

[0043] The male connector 4 is formed with a second connection plane 41 , which is parallel to a surface of one side of the restraint belt 2 and is used for connecting with the first connection plane 323 .

[0044] The heart rate belt of this embodiment accommodates the electromagnet 31 through the container 32 configured as a magnetic conductor, which not only increases the aesthetics and safety, but also increases the connection area and connection limit through the connection between the first connection plane 323 and the second connection plane 41, thereby improving the stability and comfort of the connection.

[0045] In some specific embodiments, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 The cavity 321 has an opening 322 facing one side of the restraint belt 2 , which is located on the first connecting plane 323 ; both ends of the electromagnet 31 are flush with the opening 322 .

[0046] In the heart rate belt of this embodiment, when the male connector 4 is connected to the female connector 3 , the second connecting plane 41 is connected to the first connecting plane 323 and both ends of the electromagnet 31 , thereby increasing the stability of the connection.

[0047] In some specific embodiments, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 The accommodating member 32 is formed with a first clamping plane 324, which is located at the end of the first connecting plane 323 away from the host 1, facing the host 1 and with an angle of no more than 90° with the length direction of the restraint belt 2.

[0048] The male connector 4 is formed with a second engaging surface 42 , which faces the main unit 1 and forms an angle of no more than 90° with the length direction of the restraint belt 2 .

[0049] When the male end 4 and the female end 3 of the heart rate belt of this embodiment are connected, the rebound force of the restraint belt 2 causes the first clamping plane 324 and the second clamping plane 42 to be pressed tightly. Moreover, since the angle of the clamping plane is not greater than 90°, the greater the pressing force, the less likely it is to fall off, thereby increasing the stability and reliability of the connection.

[0050] Of course, the first connecting plane 323 and the first clamping plane 324 can be located in the first groove formed on the accommodating member 32, which are respectively the bottom and the wall of the first groove; the second connecting plane 41 and the second clamping plane 42 can be located in the second groove formed on the male head 4 which is adapted to be installed with the first groove or is smaller than the first groove, which are respectively the bottom and the wall of the second groove.

[0051] In some specific embodiments, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 The accommodating member 32 is also formed with a connecting hole 325, which connects the two ends of the accommodating member 32 in the length direction of the restraint belt 2 and is adapted to the male head 4; that is, the male head 4 can be connected to the female head 3 through the connecting hole 325.

[0052] The first clamping plane 324 is located in the communicating hole 325 , so that when the male connector 4 is connected to the female connector 3 , it is located in the communicating hole 325 and connected to the electromagnet 31 , the first connecting plane 323 and the first clamping plane 324 .

[0053] The heart rate belt of this embodiment limits the male head 4 when the male head 4 and the female head 3 are connected by providing a connecting hole 325, thereby reducing the difficulty of installation; in addition, the connecting hole 325 blocks the connection between the male head 4 and the female head 3, thereby improving the aesthetics of the heart rate belt when worn.

[0054] In some specific embodiments, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 A first guide structure 326 and a second guide structure 43 are respectively provided on the side of the accommodating member 32 opposite to the first clamping plane 324 and on the side of the male head 4 opposite to the second clamping plane 42. They are inclined surfaces facing away from the host 1 and can be slidably connected to each other when docked, and are used to guide the connection between the male head 4 and the accommodating member 32.

[0055] The heart rate belt of this embodiment reduces the difficulty of connecting the male connector 4 and the female connector 3 by providing the first guide structure 326 and the second guide structure 43 on the receiving member 32 and the male connector 4 respectively, thereby improving the connection efficiency and enhancing the user experience.

[0056] In some specific embodiments, the receiving member 32 is made of silicon steel.

[0057] The heart rate belt of this embodiment uses the silicon steel material of the container 32 to make the magnetic field of the female head 3 disappear immediately when the electromagnet 31 is powered off, so that the connection between the male head 4 and the female head 3 can be disconnected when the electromagnet 31 is powered off, shortening the delay when controlling the disconnection and improving the user experience.

[0058] In some specific embodiments, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 One end of the first wire 51 and the second wire 52 are respectively connected to the two electrode springs 11, so as to enable the electromagnet 31 and the test electrode 6 to work in conjunction.

[0059] That is, when the control module controls the test electrode 6 to stop collecting current signals, the electromagnet 31 is powered off, so that the male connector 4 and the female connector 3 can be separated without special operation, which makes it convenient for users to separate the heart rate belt and improves the user experience.

[0060] In some specific embodiments, referring to Figure 2 A plurality of protrusions 7 are evenly arranged in the middle of the length direction of the restraint belt 2 and on the other side of the thickness direction to prevent detection errors caused by the movement of the restraint belt 2 carrying the host 1 and improve measurement accuracy.
