Description

Technical Field

[0001] This application relates to the field of heart rate detection technology, specifically to a wearable heart rate detection device. Background Technology

[0002] Currently, wearable heart rate monitoring devices typically use button-type connections or pin-and-hole fittings to secure the main body of the device to the accompanying strap. However, these connections require precise alignment for proper installation and power-on. After numerous installation and removal operations, the button or pin-and-hole connections are prone to oxidation or wear, severely impacting power-on stability. Furthermore, these connection methods generally require easy installation and removal, resulting in relatively large gaps at the joints. During use, sweat or other liquids can easily seep in through these gaps, corroding the circuit components on the device and strap, thus affecting the device's lifespan. Utility Model Content

[0003] This application provides a wearable heart rate monitoring device.

[0004] The wearable heart rate monitoring device according to the embodiments of this application includes a device body and a wearable strap. The wearable strap is embedded with a magnetic fastener, and the outer surface of the first side of the device body is magnetically connected to the first side of the magnetic fastener.

[0005] In some embodiments, the second side of the magnetic fastener is covered by the wearable strap.

[0006] In some embodiments, the wearable strap is provided with a current sensing element, and the second side of the magnetic fastener is in close contact with the current sensing element;

[0007] When the device is in use, the current sensing element is in close contact with the user's skin.

[0008] In some embodiments, a magnetic adsorption element is provided inside the main body of the device, and the magnetic adsorption element is arranged on the inner surface of the first side of the main body of the device.

[0009] In some embodiments, the magnetic adsorption element is ring-shaped.

[0010] In some embodiments, the magnetic adsorption element is attracted to the magnetic fixing element by a magnetic field force, wherein the magnetic field force ranges from 5N to 10N.

[0011] In some embodiments, at least one current detection contact is provided inside the device body. The current detection contact is arranged on the first surface of the device body and is in close contact with the first surface of the magnetic fastener. The current detection contact is electrically connected to a control module provided inside the device body.

[0012] In some embodiments, at least one current detection contact is provided inside the main body of the device. The current detection contact is arranged in an area surrounded by the magnetic adsorption member. The current detection contact is in close contact with the first surface of the magnetic fixing member. The current detection contact is electrically connected to a control module provided inside the main body of the device.

[0013] In some embodiments, the first surface of the magnetic fastener has at least one recessed area, and the outer surface of the first surface of the device body has at least one protruding area. When the recessed area and the protruding area cooperate, the device body is connected to the magnetic fastener in the recessed area through the protruding area.

[0014] In some embodiments, the first surface of the magnetic fastener is provided with a magnetic region and a non-magnetic region, and the device body is connected to the magnetic fastener in the magnetic region.

[0015] Thus, the wearable heart rate monitoring device in this application uses a magnetic fastener to fix the main body of the device to the wearable strap using magnetic force. The magnetic force connection maintains a tight fit between the main body of the device and the magnetic fastener, minimizing the gap between them. While ensuring the correct alignment and connection between the main body of the device and the magnetic fastener, it firstly avoids wear between them as much as possible, and secondly, it avoids sweat or other liquids from entering the gap between the main body of the device and the magnetic fastener, effectively extending the service life of the main body of the device and the wearable strap.

[0024] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0025] Please see Figure 1 The wearable heart rate detection device 10 in this application includes a device body 11 and a wearable strap 12. The wearable strap 12 is embedded with a magnetic fastener 121, and the outer surface of the first side of the device body 11 is magnetically connected to the first side of the magnetic fastener 121.

[0026] Specifically, please refer to Figure 1 , Figure 1 The embodiment of this application shows a wearable heart rate detection device 10. The device generally includes two parts: a device body 11, which receives bio-currents collected from the user's skin to further detect the user's heart rate; and a wearable strap 12. When the detection device is in normal use, the wearable strap 12 is generally wrapped around the user's chest and back, or around the user's wrist, to ensure that when the device body 11 and the wearable strap 12 are connected, the device body 11 can detect the user's heart rate through the collected bio-currents.

[0027] As a further example, a magnetic fastener 121 is embedded in the wearable strap 12. The magnetic fastener 121 generally includes a permanent magnet, such as a neodymium iron boron alloy. The main function of the magnetic fastener 121 is to use magnetic force to attract and fix the device body 11 to the magnetic fastener 121, thereby realizing a fixed connection between the device body 11 and the wearable strap 12. Specifically, the back side of the device body 11 (corresponding to the first side of the device body 11) and the side of the magnetic fastener 121 facing the device body 11 (corresponding to the first side of the magnetic fastener 121) are connected face-to-face by magnetic attraction through magnetic force, while the first side of the magnetic fastener 12 is located on the side of the wearable strap 12 that faces away from the user's skin. This connection method ensures that the first surface of the device body 11 and the first surface of the magnetic fastener 121 are tightly fitted together when connected. Compared to the connection method using a button or hole-and-shaft joint to connect the device body 11 to the connector on the wearable strap 12, the method of connecting by magnetic attraction in the above embodiment can minimize the gap between the device body 11 and the magnetic fastener 121, thereby minimizing the possibility of sweat or other liquids entering the gap and avoiding corrosion of the device body 11 and the magnetic fastener 121 by sweat or other liquids. In addition, the fixed connection between the device body 11 and the magnetic fastener 121 is achieved by magnetic attraction, which almost does not rely on friction between the contact surfaces compared to button or hole-and-shaft joints, thus minimizing wear on the contact surfaces of the device body 11 and the magnetic fastener 121. In this way, the device in the above embodiment can not only use magnetic force to fix the device body 11 to the wearable strap 12, but also minimize the wear between the device body 11 and the magnetic fastener 121, and also prevent the device body 11 and the magnetic fastener from being corroded by sweat or other liquids, thereby effectively improving the service life of the device.

[0028] Thus, the wearable heart rate monitoring device 10 in this embodiment uses magnetic force to fix the device body 11 to the wearable strap 12 by setting a magnetic fastener 121. The magnetic force connection keeps the device body 11 and the magnetic fastener 121 in close contact and minimizes the gap between them. While ensuring the correct alignment and connection between the device body 11 and the magnetic fastener 121, it firstly avoids wear between them as much as possible, and secondly, it avoids sweat or other liquids from entering the gap between the device body 11 and the magnetic fastener 121, effectively extending the service life of the device body 11 and the wearable strap 12.

[0029] In some embodiments, the second side of the magnetic fastener 121 is covered by the wearable strap 12.

[0030] Specifically, based on the above-described embodiment, the first surface of the magnetic fastener 121 faces the device body 11, while the second surface of the magnetic fastener 121 faces away from the device body 11. Considering that it is convenient to collect bioelectric currents from the skin near the user's heart or wrist during device use, and that the shape of the magnetic fastener 121 is not conducive to the accurate collection of bioelectric currents, the second surface of the magnetic fastener 121 is typically designed to be enclosed inside the wearable strap 12, thereby preventing the second surface of the magnetic fastener 121 from directly contacting the user's skin. This avoids negative impacts on the accurate collection of bioelectric currents and also prevents the magnetic fastener 121 from directly contacting the user's skin, thus minimizing the strong low-temperature sensation on the user's skin due to the properties of the magnetic fastener 121 itself, and improving the user's experience when using the device.

[0031] Please see Figure 2 In some embodiments, the wearable strap 12 is provided with a current acquisition element 122, and the second side of the magnetic fastener 121 is in close contact with the current acquisition element 122.

[0032] When the device is in use, the current acquisition element 122 is in close contact with the user's skin.

[0033] Specifically, based on the above embodiments, and exemplarily, the wearable strap 12 is further provided with a current acquisition element 122. The current acquisition element 122 generally includes a conductor sheet made of conductive material and a support structure supporting the conductor sheet. Generally, the current acquisition element 122 protrudes slightly from the surface of the wearable strap 12 facing the user. Its main function is to collect bio-currents from the user's skin through its close contact with the user's skin when the user uses the wearable heart rate detection device 10, and to conduct the bio-currents to the device body 11 through the magnetic fastener 121, so that the device body 11 can detect the user's heart rate based on the bio-currents. To achieve the above functions, on the one hand, the current acquisition element 122 is disposed on the side of the wearable strap 12 facing the user's skin. When the user uses the device and wears the wearable strap 12 on their chest, back, or wrist, the current acquisition element 122 can fit tightly against the skin near the heart or the radial artery to accurately acquire biocurrents that represent heart rate. On the other hand, the second side of the magnetic fastener 121, which is encased inside the wearable strap 12, is directly and tightly fitted with the current acquisition element 122. Under normal operating conditions, after the current acquisition element 122 acquires the biocurrent, it can directly transmit the acquired biocurrent to the device host through the conduction of the magnetic fastener 121, and finally realize heart rate detection through the device host.

[0034] For example, please refer to further information. Figure 3When a user uses the wearable heart rate monitoring device 10, the device body 11, the magnetic fastener 121, and the current acquisition device 122 are roughly located at the same position on the wearable strap 12. The device body 11 and the magnetic fastener 121 are attracted and fixed by the magnetic field. The current acquisition device 122 faces the user's skin and protrudes slightly from the outer surface of the wearable strap 12 facing the user. When the user binds the wearable strap 12 to the chest, back, or wrist, the current acquisition device 122 fits tightly against the skin around the user's heart or near the radial artery. The second side of the magnetic fastener 121 fits tightly against the current acquisition device 122 in the internal space covered by the wearable strap 12, so as to conduct the biocurrent collected by the current acquisition device 122 to the device body 11.

[0035] In some embodiments, a magnetic adsorption element 111 is provided inside the device body 11, and the magnetic adsorption element 111 is arranged on the inner surface of the first side of the device body 11.

[0036] Please see Figure 4 Furthermore, in some embodiments, the magnetic adsorption element 111 is ring-shaped.

[0037] In some embodiments, the magnetic adsorption element 111 is adsorbed to the magnetic fixing element 121 by a magnetic field force, the magnetic field force being in the range of 5N to 10N.

[0038] In some embodiments, at least one current detection contact 112 is provided inside the device body 11. The current detection contact 112 is arranged on the first surface of the device body 11 and is in close contact with the first surface of the magnetic fastener 121. The current detection contact 112 is electrically connected to the control module provided inside the device body 11.

[0039] Please see Figure 4 as well as Figure 5 Furthermore, in some embodiments, at least one current detection contact 112 is provided inside the device body 11. The current detection contact 112 is arranged in the area surrounded by the magnetic adsorption member 111. The current detection contact 112 is in close contact with the first surface of the magnetic fixing member 121. The current detection contact 112 is electrically connected to the control module provided inside the device body 11.

[0040] Specifically, based on the above embodiments, and exemplarily, a magnetic adsorption component 111 is also provided inside the device body 11. The main function of the magnetic adsorption component 111 is to be attracted to the magnetic fixing component 121 by magnetic force in the magnetic field generated by the magnetic fixing component 121, thereby connecting the device body 11 to the magnetic fixing component 121 by magnetic force. Exemplarily, the magnetic force between the magnetic fixing component 121 and the magnetic adsorption component 111 needs to ensure, on the one hand, that the connection between the device body 11 and the magnetic fixing component 121 is reliable, so that the device body 11 and the magnetic fixing component 121 will not separate in most cases when the wearable heart rate monitoring device is used; on the other hand, it needs to ensure that the magnetic induction intensity of the magnetic field required to generate the above magnetic force will not have an adverse effect on the device or the human body.

[0041] Furthermore, the magnetic adsorption component 111 is generally disposed on one side of the inner surface of the first side of the device body 11. This serves two purposes: firstly, it maintains the outer surface of the first side of the device body 11 as flat as possible when it serves as the contact surface for connection with the magnetic fixing component 121, reducing wear between the device body 11 and the magnetic fixing component 121; secondly, it ensures that the device body 11 can be adsorbed onto the magnetic fixing component 121 using magnetic force. Specifically, the magnetic adsorption component 111 can be a soft magnetic material that is not magnetic itself, such as an iron block, cobalt block, nickel block, or other alloy block with soft magnetic properties, or it can be a permanent magnet. However, it is important to note that when the magnetic adsorption component 111 is a permanent magnet, the magnetic pole of the side of the magnetic adsorption component 111 facing the magnetic fixing component 121 should be opposite to the magnetic pole of the first side of the magnetic fixing component 121 to ensure that the magnetic force between the magnetic adsorption component 111 and the magnetic fixing component 121 is an attractive force rather than a repulsive force.

[0042] Specifically, please refer to Figure 4 For example, the magnetic adsorption component 111 can be ring-shaped, and the ring-shaped magnetic adsorption component 111 is arranged on the inner surface of the first side of the device body 11. The purpose of setting the magnetic adsorption component 111 as ring-shaped is generally to regulate the position of the magnetic force when the device body 11 and the magnetic fixing component 121 are fixedly connected by magnetic force. This ensures that the connection between the device body 11 and the magnetic fixing component 121 can be correctly aligned, minimizing the frequency of user adjustment of the connection position between the device body 11 and the magnetic fixing component 121, thereby improving the user experience of the wearable heart rate monitoring device 10.

[0043] Furthermore, based on the above-described embodiments, at least one current detection contact 112 is also provided inside the device body 11. The current detection contact 112 is generally arranged on the first surface of the device body 11, and its main function is to receive the biocurrent conducted by the magnetic fixing member 121 and pass the biocurrent to the control module provided inside the device body 11 for detection, ultimately realizing the detection of the user's heart rate. Therefore, the current detection contact 112 is located inside the device body 11, its first end is connected to the control module inside the device body 11, and its second end is located on the first surface of the device body 11. One side has a contact surface. When the first surface of the device body 11 is connected to the first surface of the magnetic fixing component by magnetic force, the current detection contact 112 maintains close contact with the first surface of the magnetic fixing component 121 through the contact surface arranged on the first surface of the device body 11. When the user uses the device, the current detection contact 112 guides the biocurrent conducted by the magnetic fixing component 121 to the control module of the device body 11 through close contact with the first surface of the magnetic fixing component 121. The control module of the device body 11 then detects the biocurrent, thereby ultimately realizing the detection of the user's heart rate.

[0044] Specifically, please refer to Figure 4 For example, when the magnetic adsorption component 111 is annular, the current detection contacts 112 can also be concentrated within the circular area enclosed by the magnetic adsorption component 111. This allows the annular magnetic adsorption component 111 to define the area where the current detection contacts 112 acquire biocurrent. When the connection between the device body 11 and the magnetic fixing component 121 is correctly aligned, the biocurrent can be acquired in a relatively concentrated area through the current detection contacts 112, thereby improving the accuracy of biocurrent acquisition. Further reference is provided below. Figure 5 The current detection contact 112 has a corresponding contact surface on the first surface of the device body 11.

[0045] In some embodiments, the first surface of the magnetic fastener 121 is provided with at least one recessed area, and the outer surface of the first surface of the device body 11 is provided with at least one protruding area. When the recessed area and the protruding area cooperate, the device body 11 is connected to the magnetic fastener 121 in the recessed area through the protruding area.

[0046] Specifically, based on the above-described embodiment, the first surface of the magnetic fastener 121 can be provided with a slightly recessed area in the direction away from the device body 11, and correspondingly, the first surface of the device body 11 can be provided with a slightly convex area in the direction facing the magnetic fastener 121. The recessed size of the recessed area matches the convex size of the convex area. In this way, when the device body 11 and the magnetic fastener 121 are fixed by magnetic force, the size matching between the recessed area and the convex area, and the friction between the contact surface of the magnetic fastener 121 in the recessed area and the contact surface of the device body 11 in the convex area, can be used to hold the device body 11 against the first surface of the magnetic fastener 121. This improves the connection strength between the device body 11 and the magnetic fastener 121, and also allows the alignment position between the device body 11 and the magnetic fastener 121 to be determined in advance by the cooperation between the recessed area and the convex area, thereby improving the success rate of correct alignment between the device body 11 and the magnetic fastener 121.

[0047] In some embodiments, the first surface of the magnetic fastener 121 is provided with a magnetic area and a non-magnetic area, and the device body 11 is connected to the magnetic fastener 121 in the magnetic area.

[0048] Specifically, based on the above-described embodiments, the first surface of the magnetic fastener 121 can be divided into two parts: a magnetic region and a non-magnetic region. The magnetic region is surrounded by a magnetic field, which attracts the device body 11 and achieves connection. The non-magnetic region is not surrounded by a magnetic field, so it cannot attract the device body 11. In this way, by setting the magnetic region, the alignment position between the device body 11 and the magnetic fastener 121 can be determined in advance, thereby improving the success rate of correct alignment between the device body 11 and the magnetic fastener 121.

[0049] For example, regarding the aforementioned magnetic and non-magnetic regions, the magnetic fastener 121 can be arranged into two parts, with the permanent magnet portion corresponding to the magnetic region and the portion excluding the permanent magnet portion corresponding to the non-magnetic region. In some examples, the magnetic region is arranged in the central area of ​​the first surface of the magnetic fastener 121, and the magnetic region is surrounded by the non-magnetic region. This allows the alignment position between the device body 11 and the magnetic fastener 121 to be pre-arranged in the central area of ​​the first surface of the magnetic fastener 121, thereby improving the success rate of correct alignment between the device body 11 and the magnetic fastener 121.
