Description

Technical Field

[0001] This invention belongs to the field of swimming timer technology, specifically a pressure-sensing timer swimming glove. Background Technology

[0002] Swimming timers are used in swimming competitions and training. They are important devices for determining the time of swimmers when they reach the finish line of the lane, and are the basic equipment for realizing automated timing in swimming.

[0003] In the prior art, CN208569314U discloses a wearable smart swimming timing device, including a timer body shaped like a behind-the-ear sports earphone. The timer body has a central waterproof compartment and ear waterproof compartments. A motherboard is located inside the central waterproof compartment, and a speaker is located in each ear waterproof compartment. A central processing unit (CPU) is mounted on the motherboard and powered by a battery manager. The CPU receives motion information from a motion sensor and timing information from the timer, which is displayed on a screen. The CPU also receives infrared data signals, records time, and controls a digital-to-analog converter to output synthesized speech. The synthesized speech is then amplified through a music player and transmitted to the speaker. Its simple structure and overall sealed design allow for a better fit to the human body and waterproofing. It can also be worn inside a swimming cap, allowing the cap to completely enclose the device for added comfort.

[0004] The aforementioned patent describes a timer body shaped like a behind-the-ear sports headphone. The timer body has a central waterproof chamber and an ear waterproof chamber. The central waterproof chamber contains a motherboard, and the ear waterproof chamber contains a speaker. The motherboard contains a central processing unit, which is powered by a battery manager. This overall sealing allows for a better fit to the human body and waterproofing, making it more comfortable for users to wear. However, this swimming timer device still has some problems.

[0005] 1. This wearable swimming timing device is difficult to achieve precise timing such as touch-the-wall timing to detect the swimmer's accurate swimming performance. In situations where water movements are frequent and diverse, the device's reliance on the magnitude of acceleration and angular velocity as timing conditions is prone to timing errors and misjudgments, affecting the timing accuracy in training and competition.

[0006] 2. This wearable swimming timing device is difficult to capture the details of the movements. It only detects the magnitude of the swimmer's acceleration and angular velocity during the movement, which has limitations in data acquisition during the swimming process and may lead to inaccurate movement recognition.

[0007] Therefore, a pressure-sensing, time-capable swimming glove is proposed to address the above issues. Utility Model Content

[0013] Furthermore, an inertial measurement unit module is provided on the back of the glove body, and the inertial measurement unit module includes an accelerometer, a gyroscope and a magnetometer.

[0016] Furthermore, a water depth pressure sensor (8) is provided on the left side of the fixing ring (102) for detecting underwater pressure, and the water depth pressure sensor (8) is connected to the circuit layer.

[0020] Furthermore, a storage module is provided on the right side of the fixing ring. The storage module stores data when the wireless communication connection is disconnected to prevent data loss.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the present invention provides a pressure-sensing, time-capable swimming glove, which has the following advantages:

[0023] 1. This pressure-sensitive, time-sensitive swimming glove features a first flexible pressure sensor and a second flexible pressure sensor respectively attached to the proximal knuckles and palm of the glove body. When a swimmer swims, the bending of the fingers causes the first flexible pressure sensor located in the proximal knuckle area to undergo corresponding stretching deformation. This change in the resistance value of the first flexible pressure sensor corresponds to the change in resistance value. Since the degree of finger bending is related to the stretching deformation of the first flexible pressure sensor, finger bending can be detected. The second flexible pressure sensor located in the palm area is activated by water. When the swimmer touches the wall, a squeezing deformation occurs. The magnitude of the water force and the pressure upon touching the wall are related to the squeezing deformation. This allows the system to detect water resistance and draft during the stroke, and to detect the pressure upon touching the wall. When the system detects a rapid increase in pressure that remains above a certain threshold for a certain period of time, it marks this moment as a timing node, automatically recording and updating the swimming distance and time. After a valid wall touch, a cool-down period begins, during which new trigger signals are ignored. This avoids false timing triggers caused by multiple wall touches in a short period of time, achieving seamless and accurate wall touch timing and real-time motion data acquisition without affecting the swimmer's smooth movements.

[0024] 2. This pressure-sensing, time-capable swimming glove features an inertial measurement unit (IMU) module on the back that automatically calibrates upon startup. During swimming, the accelerometer monitors the hand's acceleration in real time to detect changes in acceleration, the gyroscope monitors the hand's rotational angular velocity to identify rotational movements, and the magnetometer senses the direction of motion to calibrate the gyroscope's drift and improve orientation recognition. By fusing data from the accelerometer, gyroscope, and magnetometer, the device's quaternion attitude in space is obtained, enabling accurate attitude tracking and identification of swimming speed, strokes, and turns.

[0025] 3. This pressure-sensing, time-sensitive swimming glove works by squeezing the two sides of the first flexible pressure sensor, causing the anti-slip teeth to move towards the center, disengaging them from the locking buckle, and releasing the limiting fixation on the first flexible pressure sensor. Pulling the first flexible pressure sensor allows it to move within the guide groove, which in turn moves the knuckle sleeve, adjusting the distance between the knuckle sleeve and the glove body to accommodate different hand shapes. This ensures the swimming glove fits the swimmer's hand snugly. A retaining ring secures the swimmer's wrist, preventing the glove from shifting or loosening, improving wearing comfort and stability, and aiding in accurate information acquisition. This enhances the device's versatility and user experience. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Specific implementation examples are given below.

[0037] Please see Figures 1-6 This utility model provides a pressure-sensing timed swimming glove, including a swimming glove 1 comprising a glove body 101, a fixing ring 102, a guide groove 103, a first flexible pressure sensor 104, a finger sleeve 105, a second flexible pressure sensor 106, a locking buckle 107, and anti-slip teeth 108. The fixing ring 102 is provided at the bottom of the glove body 101. Five guide grooves 103 are provided on the back of the glove body 101. Each guide groove 103 is provided with a first flexible pressure sensor 104, which slides within the guide groove 103. Several anti-slip teeth 108 are symmetrically fixed in two rows on the upper sides of the first flexible pressure sensor 104. Two locking buckles 107 are fixed to the inner walls on both sides of the opening of the guide groove 103. One outer end of the first flexible pressure sensor 104 is fixedly connected to the finger sleeve 105. The second flexible pressure sensor 106 is located at the palm position of the glove body 101.

[0038] Specifically, squeezing both sides of the first flexible pressure sensor 104 causes the anti-slip teeth 108 to move towards the center, disengaging the anti-slip teeth 108 from the locking buckle 107, thus releasing the limiting fixation of the first flexible pressure sensor 104. This allows the first flexible pressure sensor 104 to move within the guide groove 103, thereby moving the knuckle sleeve 105. Adjusting the distance between the knuckle sleeve 105 and the glove body 101 adapts to different users' hand shapes, ensuring the timed swimming glove fits the swimmer's hand. The fixing ring 102 secures the swimmer's wrist, preventing the glove body 101 from loosening, improving wearing comfort and stability, and aiding in accurate information acquisition. This enhances the universality of the device and the user experience. The first flexible pressure sensor 104 and the second flexible pressure sensor 106 are respectively attached to the proximal knuckles and palm of the glove body 101. The resistance value formula of the flexible pressure sensor is:

[0039] R=ρL / S

[0040] Where ρ represents the resistivity of the resistor, which is determined by its own properties, L represents the length of the resistor, and S represents the cross-sectional area of ​​the resistor.

[0041] When a swimmer is swimming, the bending of their fingers causes the first flexible pressure sensor 104, located in the proximal knuckle area, to undergo corresponding tensile deformation. At this time, the resistance value of the first flexible pressure sensor 104 also changes, that is, the change in resistance value corresponds to the degree of stretching deformation. The degree of finger bending is related to the stretching deformation of the first flexible pressure sensor 104, thus enabling the detection of finger bending. The second flexible pressure sensor 106, located in the palm area, undergoes squeezing deformation when subjected to water and when touching the wall. The magnitude of the water force and the wall contact pressure are related to the squeezing deformation, thus enabling the detection of water resistance and draft during the stroke, and the detection of wall contact pressure. When the detected pressure rapidly increases and remains above a certain threshold for a certain period of time, the system marks this moment as a timing node, automatically records and updates the swimming distance and time. After a valid wall contact, a cooling period will begin, during which new trigger signals will be ignored to avoid false timing triggers caused by multiple wall contact in a short period of time. This achieves seamless and accurate wall contact timing and real-time motion data acquisition during swimming without affecting the smoothness of the swimmer's movements.

[0042] The outer surfaces of the glove body 101, the fixing ring 102, and the finger sleeves 105 are made of elastic waterproof material;

[0043] Specifically, the glove body 101, fixing ring 102, and finger sleeve 105 are made of elastic waterproof material, which fits the swimmer's palm better while providing waterproof protection for internal circuits and modules.

[0044] The inertial measurement unit module 10 includes an accelerometer, a gyroscope, and a magnetometer;

[0045] Accelerometer: Real-time monitoring of hand movement acceleration, used to detect acceleration changes during swimming;

[0046] Gyroscope: Monitors the rotational angular velocity of the hand in real time to identify the hand's rotational movements;

[0047] Magnetometer: Sensing the direction of motion, used to calibrate gyroscope drift and improve orientation recognition;

[0048] By fusing data from accelerometers, gyroscopes, and magnetometers, the quaternion attitude of the device in space is obtained, which helps to achieve accurate attitude tracking and identify swimming speed, strokes, and turns.

[0049] An LED indicator 2 and a button 3 are provided on the left side of the fixing ring 102. Both the LED indicator 2 and the button 3 are connected to the circuit layer. The LED indicator 2 is used to display the status. The button 3 is a press-type button with an anti-accidental touch function. A micro vibration motor 7 is provided on the right side of the fixing ring 102. The micro vibration motor 7 adopts a low power consumption design. The micro vibration motor 7 is fixed in the right side interlayer of the fixing ring 102 and is connected to the circuit layer.

[0050] Specifically, button 3 is used for power on / off and start / stop timing operations. It features a press-type anti-accidental touch design, supports sensitive operation in water, and confirms the operation result through LED indicator 2 flashing and vibration feedback. When the timing function is started, the fixed ring 102 reminds the swimmer to start the timing by flashing red and yellow LED indicator 2 and generating obvious vibration feedback. During swimming, the fixed ring 102 reminds the swimmer that the timing is in progress by keeping the LED indicator 2 solid green. After successfully touching the wall, the fixed ring 102 reminds the swimmer that the timing node has been successfully recorded by flashing red and yellow LED indicator 2 and generating obvious vibration feedback.

[0051] A water depth pressure sensor 8 is provided on the left side of the fixed ring 102 for detecting underwater pressure. The water depth pressure sensor 8 is connected to the circuit layer.

[0052] Specifically, the water depth pressure sensor 8 is used to detect the underwater pressure during exercise, sense changes in water pressure in real time, and provide feedback on the swimmer's swimming depth and stroke depth.

[0053] Specifically, it senses changes in water pressure in real time, calculates the depth of the gloves, and provides feedback on the swimmer's floating status and stroke depth.

[0054] A power module 9 is provided in front of the fixing ring 102, and the power module 9 is connected to the circuit layer to provide power to other electronic components and modules.

[0055] Specifically, power module 9 is used to power the device and supports magnetic wireless charging, automatic standby, and low power mode.

[0056] The wireless communication module 5 uses Bluetooth 5.0 to transmit data to the mobile terminal in real time, ensuring the timeliness of sports data and displaying the swimmer's precise wall touch time and swimming data report on the terminal simultaneously.

[0057] A data processing module 4 is provided on the back of the fixing ring 102;

[0058] A storage module 6 is provided on the back right side of the fixing ring 102;

[0059] Specifically, the data processing module 4 processes data from the first flexible pressure sensor 104, the second flexible pressure sensor 106, the water depth pressure sensor 8, and the inertial measurement unit module 10, and uploads the motion data to the mobile terminal via the wireless communication module 5. This provides swimmers with precise wall touch time and swimming data reports, helping them analyze their performance and improve their athletic ability. If the wireless communication connection is lost, the data processing module 4 automatically caches the data to the storage module 6 to prevent data loss.

[0060] Working principle: Before swimming, squeeze both sides of the first flexible pressure sensor 104 to move the anti-slip teeth 108 towards the center, causing the anti-slip teeth 108 to disengage from the locking buckle 107, thus releasing the limiting fixation of the first flexible pressure sensor 104. Pull the first flexible pressure sensor 104 to move it within the guide groove 103, thereby moving the knuckle sleeve 105. Adjust the distance between the knuckle sleeve 105 and the glove body 101 to adapt to different users' hand shapes, ensuring the timed swimming glove fits the swimmer's hand. The fixing ring 102 secures the swimmer's wrist to prevent the glove body 101 from loosening. After putting on the timed swimming glove, the inertial measurement unit module 10 automatically calibrates upon startup. Then, the swimmer starts the glove by pressing and holding button 3. During swimming timing, the LED indicator 2 on the bottom fixing ring 102 of the glove body 101 flashes red and yellow and vibrates at intervals of one second. At the third second (the third vibration), it becomes a long vibration, and the LED indicator 2 turns green, indicating the start of timing. During swimming, the accelerometer monitors the acceleration of hand movements in real time to detect acceleration changes, the gyroscope monitors the rotational angular velocity of the hand in real time to identify rotational movements, and the magnetometer senses the direction of motion to calibrate gyroscope drift and improve direction recognition. By fusing data from the accelerometer, gyroscope, and magnetometer, the quaternion attitude of the device in space is obtained, helping to achieve accurate attitude tracking and identify swimming speed, stroke movements, and turning movements. This is achieved through the corresponding... A first flexible pressure sensor 104 and a second flexible pressure sensor 106 are respectively attached to the proximal knuckles and palm of the swimmer. When the swimmer swims, the bending of the fingers causes the first flexible pressure sensor 104 located in the proximal knuckle area to undergo corresponding tensile deformation. At this time, the resistance value of the first flexible pressure sensor 104 also changes, that is, the change in resistance value corresponds to the amount of tensile deformation. The degree of finger bending is related to the tensile deformation of the first flexible pressure sensor 104, thus realizing the detection of finger bending. The second flexible pressure sensor 106 located in the palm area undergoes compression deformation when subjected to water and when touching the wall. The magnitude of the water force and the pressure when touching the wall are related to the compression deformation, thus enabling the detection of water force and pressure during the stroke. The system measures water resistance and draft, and detects the pressure upon contact with the wall. When the pressure rapidly increases and remains above a certain threshold for a certain period, the system marks this moment as a timing node, automatically recording and updating the swimming distance and time. The data processing module 4 fuses and analyzes the data from each sensor and uploads the results to the mobile terminal via the wireless communication module, providing the swimmer with precise wall contact timing and swimming data reports to help them analyze their performance and improve their athletic ability. If the wireless communication connection is lost, the data processing module 4 automatically caches the data to the storage module 6 to prevent data loss. After swimming, the swimmer presses and holds button 3, or the inertial measurement unit module 10 does not detect any valid movement within 30 seconds.If the water depth pressure sensor 8 detects that the pressure has been close to atmospheric pressure for an extended period, the glove will exit the timing mode and enter a low-power standby mode until the swimmer reactivates the swimming timing mode.

[0061] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
