Description

Technical Field

[0001] The present application relates to the technical field of wearable electronic devices, and in particular to a wearable device and an abnormal posture reminder device thereof. Background Art

[0002] With the technological advancement of wearable devices and the growth of user demand in recent years, users are using them more and more frequently and for longer periods of time. However, when users wear wearable devices for a long time, they may suffer from pseudo-abnormal postures (improper postures) such as lowering their heads, hunching their chests, and hunching their backs. If not corrected in time, users may be in an abnormal posture state for a long time, which may easily lead to health problems.

[0003] In order to prevent the human body from being in an abnormal state for a long time, some posture correction or reminder devices have appeared on the market, such as devices that maintain a fixed posture based on physical methods, and devices that detect the distance between the human body and the target object based on infrared, ultrasonic and other ranging methods to determine whether the posture is abnormal, so as to remind when an abnormality occurs. Another example is a device that directly detects parameters such as the tilt angle of the human head and waist through devices such as mercury switches, and alarms to remind when the parameters change. These existing devices cannot be carried around, which is inconvenient for users to use in daily life. Utility Model Content

[0032] The technical solution of the present application is further elaborated in detail below in conjunction with the accompanying drawings and specific embodiments of the specification.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit the implementation of this application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] In the following description, reference is made to “some embodiments” which describe a subset of possible embodiments, but it should be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0035] Figure 1 The present invention is a three-dimensional schematic diagram of a wearable device including an abnormal posture reminder device provided according to some embodiments of the present application. Figure 2 The circuit structure diagram of the abnormal posture reminder device of the wearable device provided according to the embodiment of the present application. The wearable device provided in the embodiment of the present application includes a wearable body 100 and an abnormal posture reminder device 1 provided in the wearable body 100. The abnormal posture reminder device 1 is used to detect whether the user's posture is abnormal when the wearable device is worn by the user, so as to remind when the user's posture is abnormal. The wearable device body 100 can be a neck-hanging wearable device, such as a neck-hanging fan, a neck-hanging headset, a neck-hanging massager, and a neck-hanging speaker. In other embodiments, the wearable body 100 can also be a wearable back massager, a wearable shoulder and neck massager, etc. The wearable body 100 includes a shell, an actuator arranged on the shell, and a functional circuit board arranged in the shell. Taking the neck-hanging fan as an example, the actuator is a fan, and the functional circuit board is a fan drive control board. In some embodiments, the abnormal posture reminder device 1 is arranged in the shell of the wearable body 100, and specifically, it can be arranged on the functional circuit board in the shell.

[0036] The abnormal posture reminder device 1 specifically includes an MCU 11, and a wearing detection module 12, a posture detection module 13, and a reminder module 14 respectively connected to the MCU 11. The wearing detection module 12 is used to detect the wearing state of the wearable device and output a wearing detection signal to the MCU 11. The MCU 11 is used to control the posture detection module 13 to detect the posture of the user wearing the wearable device when it is determined that the wearable device is in the wearing state according to the wearing detection signal, and determine whether the posture of the user is abnormal according to the posture detection signal representing the user obtained by the posture detection module 13, and control the reminder module 14 to remind when it is determined that the posture of the user is abnormal.

[0037] The wearing state refers to the state in which the wearable device is worn on the user. Taking the wearable device body 100 as a neck-hanging fan as an example, the wearable device is a neck-hanging fan with a posture abnormality reminder function. When it is hung on the user's neck and turned on for use, it is in a wearing state. After the wearable device is turned on, the posture abnormality reminder device 1 enters the working state, the wearing detection module 12 detects the wearing state of the wearable device, and outputs a corresponding wearing detection signal representing whether the wearable device is in a wearing state. When the MCU11 receives the wearing detection signal, it determines whether the wearable device is currently in a wearing state based on the recognition of the wearing detection signal. When determining that the wearable device is currently in a wearing state, the MCU11 outputs a detection control instruction to the posture detection module 13 to trigger the posture detection module 13 to detect the user's posture and obtain a posture detection signal representing the user's posture. The posture detection module 13 sends the posture detection signal obtained by the detection to the MCU11. The MCU11 obtains the current user posture according to the posture detection signal, and compares the current user posture with the reference posture that represents the normal user posture to determine whether the user posture is abnormal. If the current user posture is consistent with the reference posture, it is determined that the user posture is normal, otherwise it is abnormal. When the MCU11 determines that the user posture is abnormal, it sends a reminder instruction to the reminder module 14. When the reminder module 14 receives the reminder instruction, it reminds the user that the posture is abnormal so that the user can correct it in time.

[0038] The abnormal posture reminder device 1 provided in the embodiment of the present application is arranged in the wearable body 100 of the wearable device. When it is detected that the wearable device is worn and used by the user, the user's posture is detected, and whether the user's posture is abnormal is determined based on the posture detection signal, and the user is reminded when it is determined that the user's posture is abnormal, so that the user can correct the abnormal posture in time. The wearable device provided in the present application has the function of reminding the user of abnormal posture, which helps the user to correct the posture, and has good portability and is convenient for users to use.

A second diode D52 is provided at the output terminal of the boost regulator 152 to prevent the load backflow current from damaging the boost regulator 152.

[0042] In some embodiments, the three-terminal voltage regulator 151 includes a three-terminal voltage regulator chip U51, the anode of the first diode D51 is connected to the battery to receive the voltage Vbat of the battery, and the cathode of the first diode D51 is connected to the voltage input terminal VI of the three-terminal voltage regulator chip U51. The voltage output terminal Vo of the three-terminal voltage regulator chip U51 outputs the first power supply voltage Vdd1. Further, the three-terminal voltage regulator 151 also includes a first input filter circuit connected to the voltage input terminal VI and a first output filter circuit at the voltage output terminal Vo. Among them, the first input filter circuit includes a capacitor C51 connected between the voltage input terminal VI and the ground terminal, and the first output filter circuit includes a capacitor C52 and a capacitor C53 connected in parallel between the voltage output terminal Vo and the ground terminal. Through the first input filter circuit and the first output filter circuit, the three-terminal voltage regulator 151 can obtain a purer DC output.

[0043] Please continue reading Figure 3 As shown, in some embodiments, the boost regulator is a synchronous boost regulator, specifically a synchronous boost regulator, which includes a synchronous boost chip U52 and an inductor L51.

[0044] Further, the boost regulator 152 also includes a first resistor voltage divider circuit, a second resistor voltage divider circuit, a bootstrap capacitor and an RC circuit. In addition, the boost regulator 152 also includes an input filter capacitor C4 and output filter capacitors C57 and C58.

The RC circuit includes a resistor R51 and a capacitor C56 connected in series between the first terminal of the inductor L51 and the ground terminal to absorb the peak on the switch terminal SW.

[0045] In some embodiments, the wearing detection module 12 includes a touch sensor and / or an infrared sensor. The touch sensor and / or the infrared sensor is connected to the MCU11 to output a wearing detection signal to the MCU11, and the MCU11 is used to identify the level of the wearing detection signal, and when it is identified that the level of the wearing detection signal is a set level, it is determined that the wearable device is in a wearing state.

[0046] Please refer again Figure 1 As shown, in some embodiments, the wearable device is a neck-hanging wearable device, and the wearing detection module 12 is arranged on the side of the wearable device close to or in contact with the user's neck. After the user wears the wearable device, the wearing detection module can sense that the user's neck is close to or in contact with the sensing area, and output a corresponding wearing detection signal. The wearing state of the wearable device is detected based on a touch sensor or an infrared sensor, and sent to MCU11, so that MCU11 triggers the posture detection module 13 to detect the user's posture when the wearable device is in a wearing state, and when the wearable device is in a non-wearing state, no posture detection is performed, which is simple to implement and helps to reduce the power consumption of the abnormal posture reminder device 1.

[0047] See also Figure 4As shown, in some embodiments, a touch sensor for detecting the wearing state of a wearable device includes a touch pad PAD and a touch sensing chip U2, wherein the touch pad PAD is disposed on the surface of the wearable device and is connected to the touch input terminal TCH of the touch sensing chip U2, and the sensing output terminal OUT of the touch sensing chip U2 is connected to the MCU11 to output a wearing detection signal TOHCH to the MCU. When the wearable device is in a wearing state, the touch pad PAD is touched by the user's skin, and the level of the wearing detection signal TOUCH is a set level. The set level is a high level or a low level. If the set level is a high level, then when the touch pad PAD is not touched by the user's skin, the level of the wearing detection signal TOUCH is a low level. Conversely, if the set level is a low level, then when the touch pad PAD is not touched by the user's skin, the level of the wearing detection signal TOUCH is a high level.

[0048] Please continue reading Figure 4 As shown, further, the touch sensor also includes capacitors C21, C22 and a resistor R21. The touch input terminal TCH of the touch sensing chip U2 is connected to the touch pad PAD through the resistor R21, and the hold / synchronization mode terminal HLD and the power supply terminal VDD of the touch sensing chip U2 are respectively connected to the voltage output terminal of the boost regulator 152 for receiving the second power supply voltage Vdd2. The first end of the capacitor C21 is connected to the power supply terminal VDD of the touch sensing chip U2, and the other end is grounded.

[0049] In some embodiments, the posture detection module 13 is a gyroscope sensor. The gyroscope sensor is connected to the MCU11 via an I2C data bus, and the MCU11 sends a detection control instruction to the gyroscope sensor via the I2C data bus, and the gyroscope outputs posture detection data to the MCU11 via the I2C data bus. The posture of the user is detected based on the gyroscope sensor, and the detection accuracy is higher. The data connection between the gyroscope sensor and the MCU11 is realized by using I2C, which takes up little space and has low interconnection cost.

[0050] In some embodiments, the gyro sensor used for the posture detection module 13 is a six-axis gyro sensor. However, in other embodiments, the posture detection module 13 can also be implemented by a three-axis gyro sensor or other types of gyro sensors. The six-axis gyro sensor is an integrated circuit composed of three angular velocity sensors and three acceleration sensors, which are used to measure the acceleration along three axes (x, y and z axes) and the angular velocity around three axes (x, y and z axes) respectively. The acceleration and angle detected are posture detection signals for characterizing the user's posture. The posture detection signal is transmitted to the MCU11 to determine the user's posture through the calculation of the MCU11, and then the user's posture is compared with the reference posture to determine whether the user's posture is abnormal. Among them, the user's posture includes posture angle information and motion state information. For example, if the reference posture is the posture of the user when he is not hunchbacked, if the user's posture obtained by the MCU11 based on the posture detection signal is inconsistent with the posture of the user when he is not hunchbacked, it means that the user currently has a hunchback, then it is determined that the user's posture is abnormal, and the MCU11 controls the reminder module 14 to remind the user of the hunchback. The reminder module 14 may provide reminders in the form of vibration, sound, and / or sound and light reminders.

[0052] In some embodiments, the reminder module 14 is a vibration reminder. Specifically, a schematic diagram of a circuit structure that can be implemented by the reminder module 14 is as follows: Figure 6 As shown. The reminder module 14 includes a transistor switch Q41 and a vibration motor M41. The current input end of the transistor switch Q41 is connected to the power supply end of the reminder module 14, and the power supply end of the reminder module 14 is connected to the voltage output end of the boost regulator 152, for receiving the second power supply voltage Vdd2. The current output end of the transistor switch Q41 is connected to one end of the vibration motor M41. The switch control end of the transistor switch Q41 is connected to the MCU11, for receiving the reminder control data MOTOR output by the MCU11, that is, the reminder instruction data, so as to be turned on under the control of the data, so as to turn on the power supply circuit between the second power supply voltage Vdd2 and the vibration motor M41, so that the vibration motor 41 vibrates, and the other end of the vibration motor M41 is grounded.

[0053] Please continue reading Figure 6As shown, in some embodiments, the reminder module 13 also includes a pull-up resistor R41 and a current limiting resistor R42. The pull-up resistor R41 is connected between the current input terminal and the switch control terminal of the transistor switch Q41, which can effectively avoid the false triggering of the transistor switch Q41. One end of the current limiting resistor R42 receives the reminder control data MOTOR, and the other end is connected to the switch control terminal of the transistor switch Q41, which is used to limit the driving current to prevent the instantaneous driving current from being too large, resulting in insufficient driving capability or damage to the driving chip of the transistor switch Q41.

[0054] In some embodiments, the transistor switch Q41 is a MOS transistor, the current input terminal of the transistor switch Q41 is one of the source terminal and the drain terminal, the current output terminal of the transistor switch Q41 is the other of the source terminal and the drain terminal, and the switch control terminal of the transistor switch Q41 is the gate terminal.

[0055] See also Figure 7 As shown, it is a schematic diagram of the MCU in the posture abnormality detection device provided according to some embodiments of the present application. In some embodiments, MCU11 is specifically a Bluetooth MCU, and the Bluetooth MCU sends the user posture and posture abnormality determination results obtained according to the posture detection signal to the terminal device. Specifically, the Bluetooth MCU includes a Bluetooth MCU chip U1 and a corresponding peripheral circuit. The data input and output terminals of the Bluetooth MCU chip U1 are respectively pulled up through resistors R1 and resistors R12 to connect to the voltage output terminal of the three-terminal regulator 151, and are used to receive the first power supply voltage Vdd1 to improve the stability of data transmission. The power supply terminal VDD of the Bluetooth MCU chip U1 is connected to the voltage output terminal of the three-terminal regulator 151, and is used to receive the first power supply voltage Vdd1. In addition, MCU11 also includes a bidirectional breakdown diode D11 connected between the power supply terminal VDD and the ground terminal of the Bluetooth MCU chip U1, which is used to protect the power supply terminal VDD of the Bluetooth MCU chip U1. Furthermore, MCU11 also includes a capacitor C11 connected between the power supply terminal VDD and the ground terminal of the Bluetooth MCU chip U1, and a resistor R11 connected between the power supply terminal VDD and the general input and output terminal GPIO3 of the Bluetooth MCU chip U1. The Bluetooth MCU chip U1 can be specifically a Bluetooth MCU chip U1 of the PB-03 series.

[0056] The Bluetooth MCU sends the user posture obtained according to the posture detection signal and the abnormal posture determination result determined according to the user posture to the terminal device. After the Bluetooth MCU obtains the posture detection signal detected by the posture detection module 13, it determines the user posture according to the posture detection signal, and after determining that the user's posture is an abnormal posture according to the user posture, the user posture and the determination result of whether the posture is abnormal are sent to the terminal device through the Bluetooth unit in the Bluetooth MCU chip U1, such as to the APP of the terminal device. The App of the terminal device will record the user posture, and will also send the corresponding posture abnormality reminder to the user, and will also control the vibration motor M41 to vibrate and remind, further improving the reminder effect.

[0057] In some embodiments, the wearable device provided in the embodiments of the present application is a neck-hanging fan with a posture abnormality reminder function, that is, a neck-hanging fan equipped with a posture abnormality reminder device 1, which can detect the set standard posture data in advance and store it as reference posture data. When the user turns on the neck-hanging fan and wears it, the wearing detection module 12 can detect the wearing state of the neck-hanging fan and output a wearing detection signal to the MCU11. When the MCU11 determines that the neck-hanging fan is in the wearing state according to the wearing detection signal, it will trigger the posture detection module 13 to perform posture detection on the user, including but not limited to hunchback-related, to obtain a posture detection signal representing the user's posture. After receiving the posture detection signal, the MCU11 determines the user's posture based on it and compares the user's posture with the reference posture. When the MCU11 determines that the user's posture is abnormal, it controls the vibration motor M41 in the neck-hanging fan to vibrate to remind the user that an abnormal posture such as hunchback currently occurs, thereby playing a role in assisting in correcting the posture. In other embodiments, the wearable device can also be a neck-hanging temperature control device with an abnormal posture reminder function, with a semiconductor refrigeration chip inside, so that the wearable device can be a device for cooling and temperature control, or with a semiconductor refrigeration chip and a fan inside, so that the wearable device can be a device for blowing air and cooling and temperature control.
