Description

Technical Field

[0001] This utility model relates to an earphone case, and more particularly to an earphone case capable of detecting heart rate. Background Technology

[0002] With the rapid development of smart earphone technology, TWS earphones and similar products have become increasingly popular, even becoming another essential personal item besides mobile phones. Current smart earphones generally come with a charging case. To facilitate grip and improve the user experience, these cases are typically flat or oval-shaped with rounded corners. Some cases also feature a frosted finish, resulting in a comfortable grip and making them ideal for carrying. However, for users who require heart rate monitoring, carrying a separate heart rate monitor in addition to their phone and earphones is inconvenient and increases the cost of using multiple devices, thus failing to meet their needs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an earphone case that can detect heart rate, is easy to carry, and saves on usage costs, in order to address the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] An earphone case capable of detecting heart rate includes an upper cover and a lower cover hinged together. The lower cover houses a housing for earphones. A lens is located at the center of the lower cover. A control board, a battery, and a heart rate detection board are housed within the cavity formed by the lower cover and the housing. The heart rate detection board includes a board body and an extension extending outward from the board body. A heart rate signal output terminal is located at the end of the extension. A heart rate signal input terminal is located at the edge of the control board. The heart rate signal output terminal is plugged into the heart rate signal input terminal. The board body is aligned with the lens. A heart rate detection module light emitter and a heart rate detection module light receiver are located on the board body. The light signal emitted by the heart rate detection module light emitter passes through the lens and is directed towards the skin, then reflected back to the heart rate detection module light receiver.

[0006] Preferably, the lens is a circular lens.

[0007] Preferably, the lower cover is provided with a low-frequency pulse positive contact and a low-frequency pulse negative contact, and the control motherboard is provided with a low-frequency pulse transmitting circuit. The low-frequency pulse positive contact and the low-frequency pulse negative contact are respectively electrically connected to the low-frequency pulse transmitting circuit through wires.

[0008] Preferably, both the low-frequency pulse positive contact and the low-frequency pulse negative contact are annular, with the low-frequency pulse negative contact surrounding the outside of the lens and the low-frequency pulse positive contact surrounding the outside of the low-frequency pulse negative contact.

[0009] Preferably, the radial width m of the low-frequency pulse positive contact is greater than the radial width n of the low-frequency pulse negative contact.

[0010] Preferably, the lower cover has a recess, and the low-frequency pulse positive contact is embedded and fixed in the recess.

[0011] Preferably, the control motherboard has a charging contact on the side facing the housing, and the charging contact makes electrical contact with the earphone inside the housing.

[0012] Preferably, the control motherboard has a main control chip, a storage chip and a charging management chip on the side facing the compartment, and the charging management chip is electrically connected to the battery.

[0013] Preferably, the upper cover is provided with a button for sending a heart rate detection trigger command to the control motherboard.

[0014] Preferably, the button is located near the edge of the top cover.

[0015] In the earphone case disclosed in this utility model, the upper cover, the lower cover, and the case body constitute the main structure of the earphone case. The upper cover and the lower cover have a rounded square structure, which provides a good grip when closed. Furthermore, a lens is provided at the center of the lower cover, which allows light signals for heart rate detection to be transmitted. Simultaneously, the control board, battery, and heart rate detection board are arranged in the space below the case body. The heart rate detection board and the control board are connected via a heart rate signal output terminal and a heart rate signal input terminal. This utility model independently sets the heart rate detection board from the control board, which not only reliably fixes the control board but also allows the heart rate detection board to better approach or even conform to the lens. During heart rate detection, the light signal emitted by the light emitter of the heart rate detection module on the plate passes through the lens and is directed towards the skin. The light signal is then reflected back to the light receiver of the heart rate detection module. The light receiver processes the reflected light signal and transmits the heart rate data to the control motherboard in the form of an electrical signal. Compared with the prior art, this utility model combines earphone storage and charging with heart rate detection functions, making it not only convenient to carry but also saving users' operating costs. In addition, this utility model places the heart rate detection transceiver position at the center of the lower cover, ensuring that the lens is well aligned and fits the skin when the user holds the charging case, thereby ensuring the accuracy of the heart rate detection results.

[0023] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0024] This utility model discloses an earphone case capable of detecting heart rate, combined with... Figures 1 to 7 As shown, it includes an upper cover 1 and a lower cover 2 that are hinged to each other. The lower cover 2 has a housing 3 for accommodating the earphone 100. A lens 4 is provided at the center of the lower cover 2. A control board 5, a battery 6, and a heart rate detection board 7 are provided in the cavity formed by the lower cover 2 and the housing 3. The heart rate detection board 7 includes a board body 70 and an extension 71 extending outward from the board body 70. The end of the extension 71 is provided with a heart rate signal output terminal 72. The edge of the control board 5 is provided with a heart rate signal input terminal 50. The heart rate signal output terminal 72 is inserted into the heart rate signal input terminal 50. The board body 70 is aligned with the lens 4. A heart rate detection module light emitter 74 and a heart rate detection module light receiver 73 are provided on the board body 70. The light signal emitted by the heart rate detection module light emitter 74 passes through the lens 4 and is directed towards the skin, and then reflected back to the heart rate detection module light receiver 73.

[0025] In the above structure, the upper cover 1, the lower cover 2, and the housing 3 constitute the main structure of the earphone housing. The upper cover 1 and the lower cover 2 have a rounded square structure, providing a good grip when closed. Furthermore, a lens 4 is located at the center of the lower cover 2, allowing light signals for heart rate detection to be transmitted. Simultaneously, the control motherboard 5, the battery 6, and the heart rate detection board 7 are housed in the space below the housing 3. The heart rate detection board 7 is connected to the control motherboard 5 via a heart rate signal output terminal 72 and a heart rate signal input terminal 50. This invention independently sets the heart rate detection board 7 from the control motherboard 5, reliably securing the control motherboard 5 while allowing the heart rate detection board 7 to better approach or even conform to the lens 4. During heart rate detection, the light signal emitted by the heart rate detection module light emitter 74 on the plate 70 passes through the lens 4 and is directed towards the skin. The light signal is then reflected back to the heart rate detection module light receiver 73. The heart rate detection module light receiver 73 processes the reflected light signal and transmits the heart rate data to the control motherboard 5 in the form of an electrical signal. Compared with the prior art, this utility model combines earphone storage and charging with heart rate detection functions, making it not only convenient to carry but also saving users' usage costs. At the same time, this utility model places the heart rate detection transceiver position at the center of the lower cover 2, ensuring that the lens 4 is well aligned and fits the skin when the user holds the charging case, thereby ensuring the accuracy of the heart rate detection results.

[0026] As a preferred shape, in this embodiment, the lens 4 is a circular lens. Of course, this is only a preferred embodiment of the present invention. In practical applications, the lens 4 can also be set to other shapes such as square or elliptical.

[0027] In practical applications, the control motherboard 5 can establish wireless communication with a mobile phone via a preset Bluetooth or 2.4G module. Correspondingly, an APP can be preset on the mobile phone to facilitate the display of the user's health data. Specifically, in this embodiment, the heart rate detection is implemented as follows: the heart rate detection module (model HX3605) is based on a technology called "photoplethysmography" (PPG). This method utilizes the absorption of green light by blood and reflects changes in blood flow by measuring changes in the intensity of reflected light, that is, the contraction (high blood flow results in weak reflected light) and relaxation (opposite to contraction) of the heart, thereby obtaining the corresponding heart rate data. When a user needs to monitor their heart rate, they need to hold the earphone charging case firmly with one hand, ensuring their palm completely covers and adheres to the lens. Then, by pressing a preset button, the heart rate monitoring module's light emitter emits green light of the corresponding wavelength and frequency. This green light penetrates the lens, which is completely in contact with the palm and has good light transmittance, and then shines into the blood through the skin. The reflected green light is received by the heart rate monitoring module's light receiver (model HX3605), which then generates the corresponding heart rate data. This heart rate data is then sent to the control motherboard via IIC. After receiving the data, the control motherboard (model JL7012) will synchronize the data to a preset display screen. If the control motherboard is connected to a mobile phone with a preset APP installed at this time, the heart rate data will also be displayed and recorded in the preset APP.

[0028] In addition to the heart rate detection described above, this embodiment also has a low-frequency pulse sleep-aiding effect. For details, please refer to [link / reference needed]. Figure 1 and Figure 2 The lower cover 2 is embedded with a low-frequency pulse positive contact 20 and a low-frequency pulse negative contact 21. The control motherboard 5 is provided with a low-frequency pulse transmitting circuit. The low-frequency pulse positive contact 20 and the low-frequency pulse negative contact 21 are respectively electrically connected to the low-frequency pulse transmitting circuit through wires.

[0029] The principle behind low-frequency pulse sleep aid is as follows: using CES physical therapy, low-frequency pulses of a certain intensity are used to mildly electrically stimulate the brain, thereby achieving the effect of treating or improving insomnia. Compared with existing independent handheld low-frequency pulse sleep aid products, this embodiment can both utilize the good grip of the charging case and transmit low-frequency pulse signals to the skin, resulting in a better user experience.

[0030] As a preferred embodiment, both the low-frequency pulse positive contact 20 and the low-frequency pulse negative contact 21 are annular, with the low-frequency pulse negative contact 21 surrounding the outer side of the lens 4, and the low-frequency pulse positive contact 20 surrounding the outer side of the low-frequency pulse negative contact 21. Further, the radial width m of the low-frequency pulse positive contact 20 is greater than the radial width n of the low-frequency pulse negative contact 21. The slightly wider and larger low-frequency pulse positive contact 20 provides a larger contact area with the skin, resulting in better radiation of the low-frequency pulse signal.

[0031] To simplify the cover structure, please refer to the following in this embodiment: Figure 4 The lower cover 2 has a recess 22, and the low-frequency pulse positive contact 20 is embedded and fixed in the recess 22.

[0032] In this embodiment, the control motherboard 5 charges the earphones through probes and contacts. Specifically, the control motherboard 5 has a charging contact 51 on the side facing the housing 3, and the charging contact 51 makes electrical contact with the earphones 100 inside the housing 3.

[0033] For the specific structure of the control motherboard 5, please refer to [link / reference]. Figure 5 and Figure 6 The control motherboard 5 has a main control chip 52, a storage chip 53 and a charging management chip 54 on the side facing the compartment 3. The charging management chip 54 is electrically connected to the battery 6.

[0034] Based on the above structure and principle, this utility model can be implemented in practical applications in the following ways: First, a low-frequency pulse generator is added to the charging case, which can be turned on to help with sleep through low-frequency pulses when experiencing insomnia; second, the heart rate can be synchronously detected through the heart rate detection module of the charging case, and the charging case is connected to a mobile app, which can synchronize the heart rate detection data to the mobile app; at the same time, when an abnormal heart rate is detected, the charging case can issue a reminder through vibration, displaying the heart rate data value on the screen, or issuing an alarm through a preset speaker; in addition to the low-frequency pulse sleep aid method, the charging case has a built-in white noise module that can send white noise signals to the headphones, and when the user wears the headphones, these white noise audio signals have a certain sleep aid effect.

[0035] In this embodiment, please refer to Figure 1The upper cover 1 is equipped with a button 14 for sending heart rate detection trigger commands and low-frequency pulse current output commands to the control motherboard 5. Specifically, the button 14 is located near the edge of the upper cover 1. In practical applications, when a user needs to detect their heart rate, they need to hold the Bluetooth headset charging case firmly with one hand, ensuring their palm completely covers and contacts the lens. Then, they can press the button 14 twice to activate the heart rate detection function. The heart rate detection module's light emitter emits green light of the corresponding wavelength and frequency. This green light passes through the lens, penetrates the skin, and enters the bloodstream. The reflected green light is received by the heart rate detection module's light receiver, which then generates the corresponding heart rate data. This heart rate data is sent to the main controller via IIC. After receiving the data, the main controller will synchronously display it on the screen. If the main controller is connected to the corresponding terminal device's APP at this time, the heart rate data can also be synchronously displayed and recorded in the APP. In addition, the button 14 controls the frequency and intensity of the low-frequency pulse current output by the control motherboard 5, allowing users to find a suitable pulse intensity.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
