Description

Technical Field

[0001] This utility model relates to the field of massage instrument technology, and in particular to a fascia gun with tilt angle control. Background Technology

[0002] Fascial guns, as highly effective muscle relaxation tools, are widely used in the fitness and rehabilitation fields. They work by applying high-frequency vibrations to muscles and fascia, helping to relieve muscle tension, promote blood circulation, and accelerate muscle recovery.

[0003] Currently, common methods for adjusting the vibration levels of fascia guns include button adjustment and intelligent sensor adjustment. Button adjustment typically uses one or more adjustable buttons or knobs, allowing users to adjust the vibration level by pressing the button or rotating the knob. Intelligent sensor adjustment, on the other hand, incorporates a pressure sensor within the fascia gun, automatically adjusting the vibration level based on the amount of pressure applied by the user.

[0004] However, touch buttons are prone to accidental activation, while physical buttons affect the product's aesthetics and waterproof performance. Intelligent pressure adjustment requires users to continuously apply force to the fascia gun, which does not achieve the effect of relaxing muscles. Utility Model Content

[0005] The main purpose of this invention is to propose a fascia gun with tilt control, which aims to solve the problem of accidental touch of the touch button on the fascia gun, while physical buttons would affect the product's aesthetics and waterproof performance.

[0006] To achieve the above objectives, this utility model proposes a fascia gun with tilt angle control, which includes:

[0007] A housing, wherein a driver and a controller are disposed within the housing, and the controller is electrically connected to the driver;

[0008] A massage head, at least partially disposed within the housing and drively connected to the driver;

[0009] An angle detection device is installed on the housing and electrically connected to the controller, used to detect the tilt angle of the fascia gun during use.

[0010] Preferably, the tilt angle detection device includes a tilt angle sensor, which is disposed on the housing and is used to detect the tilt angle when the fascia gun is used.

[0011] Preferably, the tilt detection device further includes a circuit board, which is disposed inside the housing relative to the tilt sensor and electrically connected to the tilt sensor, for converting the signal from the tilt sensor into an electrical signal.

[0012] Preferably, the circuit board includes a gyroscope disposed on the circuit board for detecting the angular velocity of the housing.

[0013] Preferably, the controller is a microcontroller, electrically connected to the circuit board, and used to receive electrical signals from the circuit board.

[0014] Preferably, the driver is a high-frequency motor, electrically connected to the microcontroller, used to receive signals from the microcontroller to change the vibration mode.

[0015] Preferably, the housing is a one-piece housing.

[0016] Preferably, the massage head is detachably connected to the driver, allowing for the replacement of massage heads of different shapes.

[0017] Preferably, the fascia gun with tilt control also includes a light-emitting element embedded in the housing, which is used to provide real-time feedback on the vibration mode through color changes.

[0018] Preferably, the fascia gun with tilt control further includes a wireless transmission module electrically connected to the controller, used to transmit the tilt angle detected by the tilt sensor to an external device.

[0019] In this invention, under the control of the controller, the driver drives the massage head to reciprocate, massaging the skin. An angle detection device detects the tilt angle of the fascia gun during use, allowing the controller to adjust the driver's vibration mode based on the detected angle, ensuring a more effective workout for the user. Simultaneously, the tilt detection device detects the angular velocity of the fascia gun; when the angular velocity exceeds a preset threshold, the controller stops the driver. This tilt-controlled fascia gun allows for timely understanding of the user's angle requirements, and the vibration mode can be changed simply by adjusting the angle, eliminating the need for physical buttons, thus improving the user experience and achieving greater functionality.

[0027] This invention proposes a fascia gun with tilt control, which is mainly used in the field of massage instruments.

[0028] Reference Figure 1 and Figure 2 As shown, in one embodiment of the present invention, it includes:

[0029] Housing 10, inside which a driver and a controller are disposed, and the controller is electrically connected to the driver;

[0030] Massage head 20, which is at least partially disposed within housing 10 and is connected to the driver via transmission;

[0031] The tilt angle detection device 30 is installed on the housing 10 and electrically connected to the controller. It is used to detect the tilt angle when the fascia gun is in use.

[0032] In this embodiment, the housing 10 serves as a support structure for the fascia gun. Its external dimensions can be gun-shaped or elongated cylindrical, sufficient to accommodate the driver and controller. For example, a heart-shaped housing is used in this application. The housing 10 can be made of high-temperature resistant and aging-resistant ABS plastic or more robust polycarbonate material to ensure product durability and safety. The housing 10 can be formed by combining multiple components or as a single molded structure. It has an internal cavity to accommodate the controller and driver. The controller is electrically connected to the driver to control the driver, causing it to output a preset vibration frequency and force.

[0033] In this embodiment, the massage head 20 is connected to the driver, and the massage head 20 can reciprocate under the drive of the driver, thereby massaging the human body. The end of the massage head 20 away from the human body is detachably connected to the driving end of the driver through the housing 10, so that the massage head 20 can be separated from the driver. For example, depending on the massage position, the shape and material of the surface of the massage head 20 in contact with the human body are also different. By replacing the massage head 20, the different needs of different massage areas can be met.

[0034] In this embodiment, the driver and controller are installed inside the housing 10. When the driver drives the massage head 20 to reciprocate, displacement will occur between the driver and the inner wall of the housing 10, which may cause the driver to shake inside the housing 10 or collide with the inner wall of the housing 10. To ensure the stable position between the driver and the housing 10 and to facilitate the fixing of the driver, a fixing component can be provided around the driver. The fixing component is fixedly connected to the inner wall of the housing 10 to stabilize the position of the driver inside the housing 10, reduce the noise caused by the collision between the driver and the inner wall of the housing 10, and improve the user experience.

[0035] In this embodiment, an angle detection device 30 is mounted on the housing to detect the tilt angle of the fascia gun during use. Based on traditional fascia guns, the angle detection device 30 detects the tilt angle of the fascia gun during use, and the controller can then adjust the vibration mode of the driver according to the detected tilt angle. Thus, the fascia gun can not only massage the skin, but the user can also change the vibration mode by altering the working angle of the fascia gun, achieving greater functionality and improving its practicality.

[0036] Reference Figure 2 As shown, in one embodiment, the tilt angle detection device 30 includes a tilt angle sensor 31, which is disposed on the housing 10 and is used to detect the tilt angle when the fascia gun is used.

[0037] In this embodiment, the tilt angle detection device 30 may include a tilt angle sensor 31. The tilt angle sensor 31 may be an SCL3300-D01 type MEMS tilt angle sensor with a measurement range of ±90°, covering all angle operation scenarios of the fascia gun, and an accuracy of ±0.1°, ensuring the accuracy of vibration mode switching. 2 The C digital interface is compatible with mainstream microcontrollers and simplifies circuit design. It also supports 10G vibration environments to adapt to the high-frequency vibration conditions of fascia guns. The tilt sensor 31 has a sampling frequency of 100 Hz to ensure real-time angle detection, and high-frequency vibration noise interference is eliminated through the microcontroller's built-in filter. The tilt sensor 31 can be mounted on the inner surface of the housing or embedded in the center of gravity area of ​​the housing 10, isolated from the housing 10 by silicone shock-absorbing pads to reduce interference from driver vibration on the tilt sensor 31 signal. Screws and epoxy resin are used for fixing, ensuring a rigid connection between the tilt sensor 31 and the housing 10, while preventing displacement due to drops. Furthermore, a spare tilt sensor 31 can be added to increase redundancy, and a majority voting mechanism can enhance reliability.

[0038] Reference Figure 2 As shown, in one embodiment, the tilt detection device 30 further includes a circuit board 32, which is disposed on the inner side of the housing relative to the tilt sensor 31 and is electrically connected to the tilt sensor 31, for converting the signal of the tilt sensor 31 into an electrical signal.

[0039] In this embodiment, the circuit board 32 is the core component of the electronic device and can integrate multiple electronic components. The circuit board 32 measures 60mm × 40mm and features a compact layout to ensure compatibility with the internal space of the housing 10. A controller can be mounted on the circuit board 32, positioned in the central area to shorten the signal transmission path. The tilt sensor 31 connects via I... 2 The controller is connected via a C-bus and uses the FreeRTOS real-time operating system for multi-task parallel processing.

[0040] Reference Figure 2 As shown, in one embodiment, the circuit board 32 includes a gyroscope 33, which is disposed on the circuit board 32 for detecting the angular velocity of the housing 10.

[0041] In this embodiment, the gyroscope 33 can be positioned adjacent to the controller and connected to the controller via an SPI bus to ensure signal transmission stability and anti-interference capabilities. It transmits the detected angular velocity to the controller. A MEMS-based MPU6050 three-axis gyroscope module can be selected. MEMS gyroscopes can achieve precise measurement of angular velocity, have a fast response speed, and are suitable for real-time monitoring of the dynamic state of the fascia gun. A drop detection threshold of 500° / s is set. Furthermore, accelerometer data (e.g., Z-axis acceleration > 2g) can be combined to further improve drop detection accuracy. When the fascia gun tilt angle is < 5° and the angular velocity is < 10° / s, it is determined to be horizontally placed, and the system automatically switches to standby mode. The gyroscope 33 can monitor the angular velocity of the fascia gun in real time. When the angular velocity of the fascia gun suddenly increases, the gyroscope 33 sends a signal to the controller. The controller determines whether a drop event has occurred based on the preset threshold. If so, it cuts off the drive signal sent to the driver to prevent the fascia gun from continuing to operate after a fall, thus preventing injury to the user or impact on the internal structure of the fascia gun. This serves to protect the safety of both the user and the fascia gun.

[0042] In one embodiment, the controller is a microcontroller, which is electrically connected to the circuit board 32 and is used to receive electrical signals from the circuit board 32.

[0043] In this embodiment, the controller can be a microcontroller, specifically an STM32F407. The microcontroller enables parallel processing of multiple tasks, including tilt detection and drop protection. It receives tilt data from the tilt sensor 31 and has preset angle thresholds: low intensity (0°-30°) for muscle warm-up; medium intensity (30°-60°) for deep massage; and high intensity (60°-90°) for high-impact massage. The microcontroller combines historical angle data from the tilt sensor 31 with a sliding window averaging method to avoid false switching due to momentary vibrations. Simultaneously, when the user holds the device horizontally (tilt angle ≈ 0°), it automatically switches to low-intensity vibration mode to prevent accidental triggering. When the user uses it vertically (tilt angle > 75°), the driver power is increased by 20%, enhancing the massage intensity. This covers different usage scenarios such as fitness and rehabilitation.

[0044] In this embodiment, the microcontroller employs a PID control algorithm to smoothly process the tilt angle signal, ensuring seamless switching between vibration modes. Simultaneously, a sensor redundancy verification mechanism is used to automatically switch to the previous stable vibration mode when the tilt angle data becomes abnormal.

[0045] In one embodiment, the driver is a high-frequency motor electrically connected to a microcontroller, used to receive signals from the microcontroller to change the vibration mode.

[0046] In this embodiment, a brushless DC motor is used as the high-frequency motor, which features high speed and high-frequency vibration. The high-frequency motor achieves precise speed control via a PWM signal output from a microcontroller. The microcontroller, by real-time acquisition and analysis of data from the tilt sensor 31, combined with a preset control algorithm, adjusts the PWM signal to different duty cycles, thereby controlling the high-frequency motor to operate at different speeds, achieving various vibration modes from gentle massage to deep massage. Upon detecting a drop or abnormal condition, the microcontroller immediately stops or reduces the speed of the high-frequency motor via PWM control, quickly cutting off mechanical vibration and thus providing safety protection to prevent accidental injury to the body or impact on the internal components of the fascia gun. The high-frequency motor is typically fixed inside the fascia gun using a dedicated bracket, and is coaxially mounted with the massage head. During installation, shock-absorbing rubber pads and other isolation components reduce vibration transmission to the circuit board 32 and housing 10, ensuring massage effectiveness while reducing noise and impact on internal electronic components.

[0047] In one embodiment, the housing 10 is a one-piece housing 10.

[0048] In this embodiment, the housing 10 features a one-piece molding design, eliminating the traditional design of buttons on the surface of the housing 10. This results in a clean and aesthetically pleasing product appearance. The compact internal structure allows for the precise integration of various functional modules (such as the tilt sensor 31, circuit board 32, and high-frequency motor), leading to a smaller overall size and easier portability and operation. The one-piece molding structure significantly reduces the possibility of external moisture, dust, oil, etc., entering the internal circuitry, improving the waterproof and dustproof performance of the fascia gun. Simultaneously, the integrated design reduces the risk of parts detaching after drops, enhancing overall impact resistance.

[0049] In one embodiment, the massage head 20 is detachably connected to the driver for replacing massage heads 20 of different shapes.

[0050] In this embodiment, the massage head 20 achieves a reliable mechanical and electrical connection with the driver through a standardized connection interface. To meet different massage needs, the massage head 20 can be designed in various shapes (such as spherical, elliptical, conical, etc.), and each massage head 20 adopts a unified connection standard to achieve quick replacement. For example, this embodiment uses a disassembly and connection structure that combines magnetic pre-alignment and rotation locking.

[0051] In one embodiment, the fascia gun with tilt control also includes a light-emitting element embedded in the housing 10, which is used to provide real-time feedback on the vibration mode through color changes.

[0052] In this embodiment, the light-emitting element can be a readily available and mature LED, which features rich colors, fast response speed, and low power consumption. The light-emitting element is embedded in the front panel or side area of ​​the fascia gun's integrated housing 10 and connected to a microcontroller via a flexible circuit board or micro pads. The microcontroller has PWM adjustment output capability, allowing precise control of the LED's color and brightness. When the user adjusts the fascia gun's tilt angle to change the vibration mode, the LED color transitions smoothly, reflecting the current vibration mode in real time. When the fascia gun is dropped, the LED immediately flashes as a warning, reminding the user to be careful.

[0053] In one embodiment, the fascia gun with tilt control also includes a wireless transmission module electrically connected to the controller for transmitting the tilt angle detected by the tilt sensor 31 to an external device.

[0054] In this embodiment, a Bluetooth module is preferred as the wireless transmission module, but a hybrid connection can also be achieved by combining it with a Wi-Fi module. Bluetooth modules offer advantages such as low power consumption, stable transmission, and broad compatibility with smartphones and other terminal devices. The wireless transmission module communicates with the microcontroller using a standard digital communication interface (such as UART, SPI, or I2C). 2 C) Data exchange. The microcontroller preprocesses the tilt angle data collected in real time by the tilt sensor and transmits it to the wireless transmission module through a digital interface. The wireless transmission module packages the data and broadcasts or sends it point-to-point to paired external devices (such as smartphones, tablets, or computers) via the BLE protocol, allowing users to view real-time data and historical records through an APP or dedicated software.

All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
