Description

Technical Field

[0001] This utility model belongs to the field of fascia gun technology and relates to a portable fascia gun with a horizontally positioned power supply. Background Technology

[0002] As a muscle massage device, the fascia gun can effectively help relax muscles after high-intensity exercise. It is very popular among fitness enthusiasts and outdoor sports lovers.

[0003] Fascia guns primarily utilize the crank-sliding principle, with a motor and transmission mechanism driving the massage head to reciprocate. Due to technical limitations and the constraints of their working principle, the massage points within the fascia gun's internal structure need to be perpendicular to the transmission mechanism. This is partly to facilitate user grip and partly to improve the utilization of space within the handle and extend the gun's battery life. Therefore, current fascia guns typically feature a corner structure.

[0004] With the development of massage guns, fitness enthusiasts are reluctant to use public massage guns in gyms due to hygiene concerns, and outdoor enthusiasts also want to reduce the weight of their massage guns for easier portability. Portable mini massage guns have become popular on the market. These guns are made to be only one-third or even smaller than ordinary massage guns by reducing battery size and transmission mechanism dimensions.

[0005] However, the layout of traditional fascia guns has become a technological inertia. Miniature fascia guns are already small in size, and the handles in corner layouts are much smaller than the palm of the hand. This layout is not only inconvenient to grip, but also wastes space. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a portable fascia gun with a horizontally positioned power supply. This overcomes the inertia of traditional technology by placing the power supply at the corner between the motor and the transmission mechanism, thus facilitating the use of the portable fascia gun.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A portable fascia gun with a horizontally positioned power supply includes: A housing, wherein the housing has a cavity; An electric motor is installed inside a housing, and the motor's shaft is connected to an eccentric wheel; A transmission mechanism is slidably mounted inside the housing, and the transmission mechanism is configured to be driven by an eccentric wheel and drive the massage head to reciprocate. A power source is used to provide electrical energy. The motor and the transmission mechanism form a corner, and the power supply is installed at the corner inside the housing.

[0008] Furthermore, the housing is provided with a rope threading hole.

[0009] Furthermore, the motor is an external rotor motor, and the motor is mounted inside the housing via a mounting plate; The stator of the motor is connected to the fixed plate, and the housing is provided with a positioning groove, in which the fixed plate is located.

[0010] Furthermore, a first shock-absorbing pad is provided between the fixed plate and the housing.

[0011] Furthermore, a second shock-absorbing pad is provided between the power supply and the housing.

[0012] Furthermore, in the axial projection direction of the motor, the output shaft of the motor is located within the contour of the outer edge of the eccentric wheel, so that the output shaft of the motor can extend into the eccentric frustum.

[0013] Furthermore, the transmission mechanism includes a transmission rod and a sleeve; The two ends of the transmission rod are respectively hinged to the sleeve and the eccentric wheel, and the transmission rod and the sleeve are hinged by a pin.

[0014] Furthermore, the hinge point between the transmission rod and the sleeve is located inside the sleeve.

[0015] Furthermore, a sliding bushing is provided inside the housing, the sleeve is located inside the sliding bushing, and a silicone sleeve is provided between the sliding bushing and the housing.

[0016] Furthermore, it also includes a control board, which is located above the transmission mechanism and is equipped with control buttons and a power indicator light.

[0017] By applying the technical solution of this utility model, the power supply is horizontally positioned at the corner between the motor and the transmission mechanism, effectively utilizing the previously complex and difficult-to-use gap, improving the overall utilization rate of the internal space of the casing, and meeting the miniaturization requirements of portable devices. The horizontal layout breaks away from the technical inertia of traditional corner structures, avoids redundant handles, and makes the overall shape more compact, facilitating the creation of mini, lightweight fascia guns suitable for outdoor use and portability. Eliminating the traditional handle structure solves the problem of excessively short and inconvenient handles for small fascia guns, making the entire machine easier to grip and control, and improving the user experience.

[0025] Reference Appendix Figure 1-4 As shown, a portable fascia gun with a horizontally positioned power supply 400 includes: Housing 100, wherein a cavity is provided inside the housing 100; Motor 200 is installed inside housing 100, and the shaft of motor 200 is connected to eccentric wheel 310; The transmission mechanism 300 is slidably installed inside the housing 100. The transmission mechanism 300 is configured to be driven by the eccentric wheel 310 and drive the massage head 301 to reciprocate. Power supply 400, used to provide electrical energy; In this design, the motor 200 and the transmission mechanism 300 form an angle, and the power supply 400 is installed at this angle within the housing 100. Unlike existing technologies, this invention optimizes the overall structural layout by designing the motor 200 and transmission mechanism 300 at a certain angle, and placing the power supply 400 module at this angle. This horizontal arrangement breaks away from the traditional design of a fascia gun with a vertical handle and longitudinal battery. While ensuring the functionality of internal components, it significantly improves the utilization rate of the internal space of the housing 100 and effectively compresses the overall length, contributing to a flatter, shorter overall shape, making it more suitable for portability.

[0026] By horizontally embedding the power supply module 400 at the angle between the motor 200 and the transmission mechanism 300, not only is the space wasted in the traditional handle not avoided, but the center of gravity of the whole machine is also lowered, enhancing portability and stability of use, making it especially suitable for outdoor sports, muscle relaxation after exercise and other scenarios.

[0027] In this embodiment, the housing 100 is provided with a lanyard hole 110. This structural design allows users to suspend the fascia gun on their wrist, backpack, belt, or other items via a lanyard, further enhancing the product's portability and flexibility. It is particularly suitable for mobile use in scenarios such as outdoor sports and travel fitness.

[0028] Furthermore, the placement of the lanyard hole 110 does not affect the overall structural strength of the housing 100. It can be placed on the side, top, or tail of the housing 100 according to specific design requirements, exhibiting good compatibility and adaptability. While ensuring ease of use, it does not increase the product's size and weight, which aligns with the lightweight and portable overall design concept pursued by this utility model.

[0029] In this embodiment, the motor 200 is an external rotor motor 200, and the motor 200 is installed in the housing 100 via a fixing plate 210; The stator of the motor 200 is connected to the fixed plate 210. A positioning groove 120 is provided within the housing 100, and the fixed plate 210 is located within the positioning groove 120. Unlike the common method in existing technologies where the motor 200 is fixed to the housing 100 via a metal bracket and screws, this technical solution eliminates the traditional screw mounting structure. By designing the positioning groove 120 within the housing 100, the fixed plate 210 can be directly inserted for positioning and achieve a snap-fit ​​or compression engagement. This method not only simplifies the assembly process and reduces manufacturing and maintenance costs, but also effectively reduces structural layers and installation thickness, contributing to the flattened design of the entire machine.

[0030] In addition, the positioning groove 120 structure can maintain the installation stability of the motor 200 and avoid long-term use problems caused by loose screws, thereby improving the durability and structural reliability of the fascia gun and further meeting the design intention of this utility model in terms of compactness, small size and easy assembly.

[0031] In this embodiment, a first shock-absorbing pad 220 is provided between the fixed disk 210 and the housing 100. This structural design has the following two technical effects: First, the motor 200 will generate a certain amount of vibration and noise during operation. By adding a shock-absorbing pad between the fixed plate 210 and the housing 100, the mechanical vibration caused by the high-speed operation of the motor 200 can be effectively absorbed and buffered. At the same time, the transmission and diffusion of vibration to the housing 100 are reduced, thereby achieving the purpose of shock absorption and noise reduction, and improving the user's comfort and experience during use.

[0032] Secondly, the shock-absorbing pad itself has a certain degree of resilience and compressive strength. When installed, it forms a certain pre-tightening force with the fixed plate 210, which helps to enhance the stability of the fixed plate 210 in the positioning groove 120, prevent it from loosening or shifting during long-term use, and further improve the reliability and structural stability of the motor 200 installation.

[0033] In summary, the first shock-absorbing pad 220 not only improves the smoothness and quietness of the fascia gun's operation, but also optimizes the installation and fixing method of the motor 200 through flexible structural design, making it an important auxiliary design for achieving a high-performance, miniaturized fascia gun.

[0034] In this embodiment, a second shock-absorbing pad is provided between the power supply 400 and the housing 100. This second shock-absorbing pad effectively absorbs the mechanical impact and vibration generated during operation or transport of the fascia gun, reducing the impact of vibration on the battery cell structure, thereby improving the safety and reliability of the power supply 400 module and extending its service life. Furthermore, the elastic deformation characteristics of the shock-absorbing pad allow the power supply 400 to form a flexible clamping structure inside the housing 100, providing a certain degree of restraint and preventing the power supply 400 from shaking, shifting, or loosening inside the housing 100, thus improving the overall compactness and consistency of the structure.

[0035] In this embodiment, in the axial projection direction of the motor 200, the output shaft 230 of the motor 200 is located within the contour of the outer edge of the eccentric wheel 310, allowing the output shaft 230 of the motor 200 to extend into the eccentric frustum. This structural design aims to maximize the compression of the space occupied by the motor 200 output shaft 230 and the eccentric wheel 310 in the axial direction while ensuring the integrity of the eccentric transmission function. This insertion-type overlap method achieves a high degree of integration. It further reduces the overall size of the fascia gun, contributing to the miniaturization of the product and meeting the trend towards portability.

[0036] In this embodiment, the transmission mechanism 300 includes a transmission rod 320 and a sleeve 330; The two ends of the transmission rod 320 are hinged to the sleeve 330 and the eccentric wheel 310, respectively. The transmission rod 320 and the sleeve 330 are hinged together by a pin 340. By replacing the shaft structure with the pin 340 structure, the bearing housing, bushing, and other mating components are eliminated. While ensuring the stability of the hinged function, the structural footprint of this transmission connection part in the width direction of the housing 100 is significantly reduced. That is, the transmission assembly can be effectively installed within a smaller lateral dimension.

[0037] In this embodiment, the hinge between the transmission rod 320 and the sleeve 330 is located inside the sleeve 330. By rationally designing the rotation radius of the eccentric wheel 310 and the connection angle with the transmission rod 320, this structural design differs from traditional external hinge methods. By bringing the hinge point closer to the inside of the sleeve 330, not only is the hinged part protected from external interference, but the total axial length of the transmission mechanism 300 is also further reduced. That is, while ensuring transmission function and connection strength, the space required for the transmission path is made more compact.

[0038] In this embodiment, a sliding bushing 350 is provided inside the housing 100, and a sleeve 330 is located inside the sliding bushing 350. A silicone sleeve 360 ​​is provided between the sliding bushing 350 and the housing 100. To further optimize the stability and comfort of the transmission mechanism 300 during operation, a silicone sleeve 360 ​​is provided between the sliding bushing 350 and the housing 100. That is, a flexible buffer material is wrapped around the outside of the sliding bushing 350, forming a flexible fit with the inner wall of the housing 100. When the transmission mechanism 300 reciprocates at high speed, it can effectively absorb the small vibrations and impacts generated during mechanical movement, thereby reducing the noise and vibration during the operation of the whole machine and improving the user experience.

[0039] This embodiment also includes a control board 600, located above the transmission mechanism 300. The control board 600 is equipped with control buttons 610 and a power indicator light 620. To improve ease of operation, the control board 600 is equipped with control buttons 610 and a power indicator light 620. Control buttons 610 are used for functions such as turning the device on / off, starting / stopping the motor 200, and shifting gears. The power indicator light 620 is used to display the current battery level in real time, allowing users to easily monitor the remaining power and recharge the battery promptly.

[0040] In particular, the position of the control panel 600 is ergonomically optimized so that when the user holds the fascia gun normally, the thumb can naturally rest in the area of ​​the control panel 600, making it easy to operate with one hand. This layout avoids the inconvenience of traditional fascia guns requiring "reverse-hand button pressing" or "blind pressing," improving the intuitiveness of the product's operation and the comfort of use.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
