Description

Technical Field

[0001] The present invention belongs to the technical field of fascia guns and relates to a portable mini fascia gun. Background Art

[0002] As a muscle massage device, a fascia gun can effectively assist muscle relaxation after high-intensity exercise. It is deeply loved by fitness enthusiasts and outdoor sports enthusiasts.

[0003] The fascia gun mainly uses the crank-sliding principle, and drives the massage head to make a reciprocating motion through the cooperation of the motor and the transmission mechanism. Due to technical reasons and the limitations of the working principle, in the internal structure of the fascia gun, the motor needs to be vertically distributed with the transmission mechanism. On the one hand, a handle is required for the convenience of the user to hold. On the other hand, in order to improve the space utilization rate inside the handle and improve the battery life of the fascia gun, the existing fascia guns in the prior art are all corner structures.

[0004] With the development of fascia guns, fitness enthusiasts are reluctant to use public fascia guns in gyms due to hygiene factors, and outdoor enthusiasts also hope to reduce the weight of the fascia gun for easy carrying. Portable mini fascia guns have become popular on the market. Such fascia guns are made to be only one-third or even smaller than ordinary fascia guns by reducing the size of the battery and the transmission mechanism.

[0005] However, the layout of traditional fascia guns has formed a technical inertia. For a mini fascia gun, its volume is relatively small. At this time, the handle reserved by the corner layout is much smaller than the size of the palm. This layout is not only inconvenient to grasp but also causes space waste. Summary of the Invention

[0006] The purpose of the present invention is to provide a portable mini fascia gun aiming at the deficiencies of the prior art, aiming to solve the problems that the internal structure of the existing fascia gun is complex, the requirement for the shell space is large, resulting in a relatively large overall volume of the fascia gun and inconvenient to carry.

[0007] To achieve the above purpose, the present invention adopts the following technical solutions:

[0014] Further, an eccentric frustum is provided on the eccentric wheel, and the central axis of the eccentric frustum is offset from the output shaft of the motor;

[0015] In the axial projection direction, the output shaft of the motor is located within the contour of the outer edge of the eccentric frustum, enabling the output shaft of the motor to extend into the eccentric frustum.

[0016] Further, a circular groove is provided at one end of the transmission rod, and one end of the transmission rod is sleeved outside the eccentric frustum through the circular groove, and a bearing is provided between the eccentric frustum and the transmission rod.

[0019] Among them, the sum of the maximum radius r of the outer wall of the circular groove and the eccentricity d of the eccentric frustum is less than the radius R of the fixing plate, so that the outer diameter of the circumferential displacement trajectory of the transmission rod is less than the outer diameter of the fixing plate.

[0020] Further, a first shock pad is provided on the outer side wall of the fixing plate, and the first shock pad is located between the fixing plate and the housing.

[0022] Further, a positioning hole is provided on the side wall of the sleeve, a through hole is provided on the transmission rod, and a pin is provided in the positioning hole and the through hole to realize the hinge connection between the transmission rod and the sleeve.

[0023] Further, a bushing is provided between the transmission rod and the sleeve, and the bushing is in close contact with the inner wall of the sleeve;

[0024] The bushing extends into the through hole, and the bushing is located between the inner wall of the through hole and the pin.

[0025] Further, a sliding bushing is provided inside the housing, the sleeve is located inside the sliding bushing, and a silica gel sleeve is provided between the sliding bushing and the housing.

[0026] Further, it further includes a control board, the control board is located above the transmission mechanism, and operation buttons and a power indicator light are provided on the control board.

[0027] Applying the technical solution of the present invention, the power supply is horizontally arranged at the corner of the motor and the transmission mechanism, effectively utilizing the originally complex and difficult-to-utilize gap, improving the overall utilization rate of the internal space of the housing, and meeting the miniaturization requirements of portable devices. The horizontal layout breaks the technical inertia of the traditional corner structure, avoids redundant handles, makes the overall shape more compact, is conducive to creating a mini and portable fascia gun, and is suitable for outdoor use and carrying around.

[0043] Refer to the attached Figures 1-3 As shown, a portable mini fascia gun includes:

[0044] A housing 100, with a cavity provided inside the housing 100;

[0045] A motor 200, installed inside the housing 100, and the rotating shaft of the motor 200 is connected to an eccentric wheel 300;

[0046] A transmission mechanism 400, slidably installed inside the housing 100, and the transmission mechanism 400 is configured to be driven by the eccentric wheel 300 and drive the massage head 10 to reciprocate;

[0047] A power supply 500, used to provide electrical energy;

[0048] Among them, a corner is formed between the motor 200 and the transmission mechanism 400, and the power supply 500 is installed at the corner inside the housing 100 to make the housing 100 flat. Different from the prior art, in the present invention, by optimizing the overall structural layout, a corner structure with a certain included angle is designed between the motor 200 and the transmission mechanism 400, and the power supply 500 module is arranged at this corner. This horizontal layout breaks the inertia of the traditional percussion massager's vertical handle plus longitudinal battery design. On the premise of ensuring the complete functions of the internal components, it significantly improves the utilization rate of the internal space of the housing 100 and effectively compresses the overall length of the machine, which helps the overall shape of the machine to develop towards flat and short-axis, and thus is more suitable for carrying around.

[0049] Refer to the attached Figures 2-6 As shown, in this embodiment, an eccentric frustum 310 is provided on the eccentric wheel 300, and the central axis of the eccentric frustum 310 is offset from the output shaft 210 of the motor 200;

[0050] In the axial projection direction, the output shaft 210 of the motor 200 is located within the contour of the outer edge of the eccentric frustum 310, so that the output shaft 210 of the motor 200 can extend into the eccentric frustum 310. The traditional percussion massager adopts the eccentric wheel 300 structure, which causes the bearing 412 to be necessarily arranged above the rotating shaft of the motor 200, occupying a large longitudinal space. This structural design aims to, on the basis of ensuring the complete eccentric transmission function, maximize the compression of the occupied space of the two in the axial direction through the longitudinal overlap of the output shaft 210 of the motor 200 and the eccentric wheel 300 structure. Through the plug-in overlap method, high integration is achieved. Further compresses the size of the whole percussion massager, which helps to realize the ultra-small design of the product and meet the trend of portability.

[0051] In this embodiment, a circular groove 411 is provided at one end of the transmission rod 410, and one end of the transmission rod 410 is sleeved outside the eccentric frustum 310 through the circular groove 411, and a bearing 412 is provided between the eccentric frustum 310 and the transmission rod 410. This solution installs the eccentric frustum 310 on the output shaft 210 of the motor 200 and makes its central axis offset from the rotating shaft of the motor 200, so as to provide sufficient space in the horizontal direction, avoid direct interference between the bearing 412 and the shaft of the motor 200, and at the same time reduce the overall height dimension of the percussion massager.

[0052] In this solution, a circular groove 411 is provided at one end of the transmission rod 410. It is sleeved outside the eccentric frustum 310 through a bearing 412. The position of the bearing 412 is optimized so that it does not have to be higher than the rotating shaft of the motor 200, thereby reducing the overall height. The space utilization is maximized. In the axial projection direction, the output shaft 210 of the motor 200 is located within the contour of the eccentric frustum 310, that is, the shaft of the motor 200 can be partially embedded in the eccentric frustum 310. This reduces the height occupation of the bearing 412 relative to the shaft of the motor 200 and makes the overall structure more compact.

[0053] In this embodiment, the motor 200 is an outer rotor motor, and the motor 200 is installed in the housing 100 through a fixing plate 220;

[0054] The maximum radius r of the outer wall of the circular groove 411, the eccentricity d of the eccentric frustum 310, and the radius R of the fixing plate 220;

[0055] Among them, the sum of the maximum radius r of the outer wall of the circular groove 411 and the eccentricity d of the eccentric frustum 310 is less than the radius R of the fixing plate 220, so that the outer diameter of the circumferential displacement trajectory of the transmission rod 410 is less than the outer diameter of the fixing plate 220.

[0056] By making the sum of the maximum radius of the outer wall of the circular groove 411 and the eccentricity less than the radius of the fixing plate 220, it is ensured that the movement trajectory of the transmission rod 410 will not exceed the outer wall contour of the fixing plate 220, making the fascia gun more miniaturized. The eccentric frustum 310 is installed on the output shaft 210 of the motor 200. Since its central axis is offset from the shaft of the motor 200, an eccentric movement is generated during rotation. The transmission rod 410 is sleeved outside the eccentric frustum 310 through the circular groove 411 and transmits the movement through the bearing 412, causing the end of the transmission rod 410 to perform a reciprocating movement in the horizontal direction, and finally driving the massage head 10 to perform impact massage. The parameter constraint r + d < R means that the maximum movement range of the transmission rod 410, that is, the outer diameter trajectory, is always less than the radius of the fixing plate 220, ensuring its reasonable movement within the structure and not exceeding the outer diameter of the fixing plate 220. This design makes the overall structure more compact, avoids excessive space occupation, and makes the overall device more compact and portable.

[0057] In this embodiment, a first shock pad 221 is provided on the outer sidewall of the fixed disk 220, and the first shock pad 221 is located between the fixed disk 220 and the housing 100. The stator of the motor 200 is connected to the fixed disk 220. A positioning groove 110 is provided in the housing 100, and the fixed disk 220 is located in the positioning groove 110. Different from the common method in the prior art where the motor 200 is fixed to the housing 100 through a metal bracket and screws, this technical solution eliminates the traditional screw installation structure. By designing the positioning groove 110 in the housing 100, the fixed disk 220 can be directly inserted and positioned to achieve snap - fit or press - fit. This method not only simplifies the assembly process, reduces the manufacturing and maintenance costs, but also effectively reduces the structural levels and installation thickness, contributing to the flat design of the whole machine.

[0058] In addition, the structure of the positioning groove 110 can also avoid the problems caused by screw loosening during long - term use while maintaining the installation stability of the motor 200, improving the durability and structural reliability of the fascia gun, and further meeting the design concept of the present invention in the direction of being compact, small, and easy to assemble.

[0059] First of all, during the operation of the motor 200, certain amplitude of vibration and noise will be generated. By adding a shock pad between the fixed disk 220 and the housing 100, it can effectively absorb and buffer the mechanical vibration caused by the high - speed rotation of the motor 200, and at the same time reduce the conduction and diffusion of vibration to the housing 100, so as to achieve the purpose of shock absorption and noise reduction, and improve the comfort and experience of users during the use process.

[0060] Secondly, the shock pad itself has certain resilience and compressive resistance, and forms a certain pre - tightening force with the fixed disk 220 in the installed state, which helps to enhance the stability of the fixed disk 220 in the positioning groove 110, prevent it from loosening or displacing during long - term use, and further improve the reliability and structural stability of the installation of the motor 200.

[0061] Refer to the appendix Figures 3-9As shown in the figure, in this embodiment, the transmission mechanism 400 includes a transmission rod 410 and a sleeve 420. The two ends of the transmission rod 410 are respectively hinged to the sleeve 420 and the eccentric wheel 300. The hinged part of the transmission rod 410 and the sleeve 420 is located inside the sleeve 420. In existing muscle massagers, the hinged connection between the transmission rod 410 and the sleeve 420 is mainly achieved by the cooperation of a bearing 412 and a rotating shaft. However, in a portable muscle massager, this hinged connection method has two disadvantages. On the one hand, in the way of hinged connection through the rotating shaft, the width of the rotating shaft is relatively large, which is not conducive to controlling the thickness of the portable muscle massager. On the other hand, the fixing method of the rotating shaft makes the hinged point of the transmission rod 410 and the sleeve 420 located at the rear end of the sleeve 420. This hinged structure makes the length of the sleeve 420 too long, which is not conducive to controlling the length of the portable muscle massager. By setting the hinged point of the transmission rod 410 and the sleeve 420 inside the sleeve 420, the length of the transmission path is significantly shortened, avoiding the problem of long structure caused by the traditional external rotating shaft, effectively reducing the overall longitudinal size of the muscle massager, and meeting the compact layout requirements of portable products.

[0062] In this embodiment, the outer diameter of the transmission rod 410 is smaller than the inner diameter of the sleeve 420, that is, the transmission rod 410 does not cause radial interference inside the sleeve 420, ensuring that while realizing the hinged function, it will not hinder the axial sliding movement of the sleeve 420. This structural cooperation enables the transmission rod 410 to swing smoothly during the eccentric drive, and the sleeve 420 can still reciprocate smoothly in the sliding bushing 450, ensuring the coordination and smoothness of the overall operation of the transmission mechanism 400.

[0063] In this embodiment, a positioning hole 421 is provided on the side wall of the sleeve 420, and a through hole 413 is provided on the transmission rod 410. A pin 430 is provided in the positioning hole 421 and the through hole 413 to realize the hinged connection between the transmission rod 410 and the sleeve 420. Specifically, a positioning hole 421 is opened on the side wall of the sleeve 420 for the radial introduction of the pin 430. The transmission rod 410 is provided with a through hole 413 at the position corresponding to the sleeve 420, and this through hole 413 corresponds to the positioning hole 421 on the sleeve 420. During the assembly process, by passing the pin 430 through the positioning hole 421 and the through hole 413 in sequence, the rotatable connection between the transmission rod 410 and the sleeve 420 can be realized.

[0064] Compared with the traditional hinged connection method using a rotating shaft or a bearing 412 structure, the diameter of the pin 430 component can be designed smaller, with high fitting precision, effectively reducing the space occupied by the hinged structure in the width direction, which is very suitable for the structural requirements of portable and miniaturized muscle massagers; effectively reducing the space occupied by the hinged structure in the width direction, which is very suitable for the structural requirements of portable and miniaturized muscle massagers.

[0065] In this embodiment, a bushing 440 is provided between the transmission rod 410 and the sleeve 420, and the bushing 440 is in close contact with the inner wall of the sleeve 420;

[0066] The bushing 440 extends into the through hole 413, and the bushing 440 is located between the inner wall of the through hole 413 and the pin 430. It is used to improve the connection stability and operation smoothness of the hinge part. Specifically, the bushing 440 is sleeved on the outside of the transmission rod 410 and installed inside the sleeve 420, and its outer wall is in close fit with the inner wall of the sleeve 420. The bushing 440 is preferably made of a material with good wear resistance and certain elasticity. On the one hand, the close contact between the bushing 440 and the inner wall of the sleeve 420 can effectively fill the gap between the transmission rod 410 and the sleeve 420, improve the positioning accuracy of the connection part, prevent shaking or vibration caused by too large a gap, and contribute to improving the operation stability of the overall transmission system; on the other hand, as a transition buffer layer, the bushing 440 can absorb part of the impact force and vibration during the movement of the transmission rod 410, thereby reducing the friction noise between components and extending the service life of key components, especially the sleeve 420 and the pin 430; at the same time, the bushing 440 also has a good lubricating effect, which can reduce the sliding resistance and wear during high-frequency reciprocating motion, and further improve the smoothness and quiet performance of the whole machine operation.

[0067] The bushing 440 extends into the through hole 413, and the bushing 440 is located between the inner wall of the through hole 413 and the pin 430. On the one hand, the bushing 440 forms an interference or fitting buffer layer inside the through hole 413, which can effectively absorb the shaking clearance caused by the assembly tolerance between the pin 430 and the through hole 413, and improve the positioning accuracy and structural stability of the pin 430; on the other hand, the material of the bushing 440 itself has good flexibility and wear resistance, and its location around the pin 430 can play a role in buffering, anti-wear and noise reduction, avoiding direct friction between the pin 430 and metal parts during high-frequency movement, resulting in noise or damage; at the same time, this design can also reduce the axial and radial wear of the pin 430 during movement to a certain extent, extend the service life of the pin 430, and improve the reliability and service life of the whole machine transmission system.

[0068] In this embodiment, a sliding bushing 450 is provided inside the housing 100. The sleeve 420 is located inside the sliding bushing 450, and a silica gel sleeve 451 is provided between the sliding bushing 450 and the housing 100. To further optimize the stability and comfort during the operation of the transmission mechanism 400, a silica gel sleeve 451 is provided between the sliding bushing 450 and the housing 100, that is, a flexible buffer material is wrapped around the outside of the sliding bushing 450 to form a flexible fit with the inner wall of the housing 100. When the transmission mechanism 400 reciprocates at high speed, it can effectively absorb the minute vibrations and impact forces generated during the mechanical movement, thereby reducing the noise and vibration during the operation of the whole machine and enhancing the user experience.

[0069] Refer to the attached Figures 1-2 As shown, in this embodiment, it further includes a control board 600. The control board 600 is located above the transmission mechanism 400, and operation buttons 610 and a power indicator light 620 are provided on the control board 600. To improve the operation convenience, operation buttons 610 and a power indicator light 620 are provided on the control board 600. The operation buttons 610 are used for operations such as turning on / off the device, starting / stopping the motor 200, and gear shifting, and the power indicator light 620 is used to display the current battery power status in real time, facilitating the user to master the remaining power and charge in time during use.

[0070] Particularly, the position of the control board 600 is optimized in accordance with ergonomics. When the user normally holds the percussion massager, the thumb can naturally fall on the area of the control board 600, facilitating one-handed operation. This layout avoids the inconvenience of the traditional percussion massager that requires "pressing the button with the backhand" or "blind pressing", and improves the operation intuitiveness and use comfort of the product.

[0071] After the motor is started, its output shaft drives the eccentric wheel to rotate. The eccentric circular platform of the eccentric wheel generates eccentric motion, and the power is transmitted to the transmission rod through the bearing located outside the eccentric circular platform. One end of the transmission rod makes a circular motion around the eccentric circular platform. Since the other end is hinged to the sleeve and restricted by the sliding bushing structure, this circular motion is converted into a reciprocating linear motion of the sleeve along the axial direction of the percussion massager, thereby driving the front massage head to perform periodic impacts and realizing the relaxation massage effect on the muscles.

[0072] In this process, multiple structural optimizations work together:

[0073] The overlapping of the axial projections of the eccentric circular platform and the output shaft and the embedded design reduce the height of the driving mechanism;

[0074] The trajectory limit design of r + d < R ensures that the transmission rod always moves within the contour of the fixed disk, avoiding structural overflow;

[0075] A variety of hinged structures (such as pin type, boss type, positioning bead type) are combined with bushing assistance to improve assembly accuracy and transmission smoothness;

[0076] The combined structure of the sliding bushing and the silica gel sleeve realizes shock absorption and noise reduction during operation;

[0077] The power supply is horizontally placed inside the corner formed by the motor and the transmission mechanism, maximizing the utilization rate of the internal space and compressing the overall length of the machine;

[0078] The control board is set in the area that is easy for users to operate, facilitating users to adjust the gear, turn on / off the power supply and check the power level through the control buttons.

[0079] Through the above structural cooperation and process path design, the present invention realizes an efficient power conversion process of rotation - eccentricity - reciprocation, and on the basis of ensuring the realization of the massage function, achieves the high integration, size compression and function optimization of the overall device, which is particularly suitable for the scenario of personal health massage devices with strict requirements for portability and miniaturization.

[0080] In summary, through multi - aspect optimization of the internal structure of the fascia gun, the present invention proposes an overall scheme for a miniaturized fascia gun suitable for portable application scenarios. Specifically, it includes:

[0081] By arranging the motor 200 and the transmission mechanism 400 in a corner layout and embedding the power supply 500 module at the corner, the utilization rate of the internal space of the housing 100 is effectively improved, and the overall structure of the fascia gun is flattened and miniaturized;

[0082] By optimizing the spatial relationship between the eccentric wheel 300 and the output shaft 210 of the motor 200, the axial projection of the output shaft 210 falls within the contour range of the eccentric wheel 300, minimizing the longitudinal space occupation;

[0083] By setting a circular groove 411 on the outer side of the eccentric frustum 310 and cooperating with a bearing 412, and the parameter design satisfies the constraint relationship of r + d < R, it is ensured that the movement trajectory of the transmission rod 410 does not exceed the outer diameter of the fixed disk 220, further compressing the overall size of the machine and optimizing the spatial layout;

[0084] By adopting a variety of lightweight and compact hinged structures of the transmission rod 410 and the sleeve 420 such as pin 430 type, boss type or positioning bead type, the length and width of the transmission mechanism 400 are effectively reduced, and the overall compactness of the fascia gun is improved;

[0085] By setting the flexible buffer structure of the sliding bushing 450 and the silica gel sleeve 451, the vibration and noise are reduced, and the comfort and durability of the miniaturized fascia gun in a high - frequency operation environment are improved;

[0086] The layout of the control panel 600 optimized by ergonomics takes into account both the portable size and the convenience of single-handed operation, enhancing the user experience.

[0087] Through the above multi-dimensional structural innovations, the present invention has successfully achieved the high integration and extreme miniaturization of the fascia gun product, significantly improving the portability, controllability and use comfort, and having good application prospects and market competitiveness.

[0088] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
