Description

Fascia massage device Technical Field

[0001] The present application relates to the technical field of medical care equipment, and in particular to a fascia massage device. Background Art

[0002] Massage devices are now common tools for relaxation and wellness. For example, a fascia gun is an excellent tool for post-workout stretching and recovery. Muscle soreness is common in life, and everyone from professional athletes to casual fitness enthusiasts has experienced it. A fascia gun uses vibrations to massage large muscle groups, relaxing the fascia and reducing soreness. It can be used by both professional athletes and amateur fitness enthusiasts, making training more effective. The vibration frequency of a fascia gun relieves muscle spasms, increases blood flow, and significantly shortens muscle recovery time. However, currently available fascia guns generally suffer from high vibration noise and poor operational stability. Furthermore, these guns only offer a single massage depth. Due to the varying thickness of fascia layers across the body, such as the head, hands, legs, buttocks, and back, the depth of the fascia varies, requiring the massage head to adjust accordingly, something traditional fascia guns cannot do.

[0003] Therefore, it is necessary to provide a fascia massage device with smooth operation, low noise and adjustable stroke to solve the problems of existing fascia guns on the market that the massage head movement depth cannot be adjusted, the noise is loud and the stability is poor.

Beneficial effects

[0026] Compared with the existing technology, this application has the following advantages:

[0027] The fascia massage device of the present application is directly connected to the driving eccentric wheel through the driver, combined with the lateral movement of the sliding part in the eccentric wheel and the movement of the transmission connecting rod and the massage part to achieve a massage vibration effect. The structure is simple and compact. Since the eccentric wheel is directly connected to the driver output shaft, it can be set close to the end face of the driver output end, and the operation is more stable and reliable.

[0028] This application utilizes a hollow shaft driver and incorporates an adjustment link within the driver's hollow shaft, aligning the center of the adjustment assembly with the driver. This eliminates the vibration and inertial torque generated by the eccentricity between the adjustment assembly and the driver, making the driver's operation more labor-efficient and stable, while also reducing product vibration and noise. The driver's center of gravity during rotation is aligned with the center of gravity of the adjustment assembly, reducing the risk of yaw and extending product life. The adjustment assembly is positioned away from the driver's end face, saving the space otherwise added by the adjustment assembly. This allows the eccentric's center of gravity to be infinitely close to the driver's end face, shortening the torque between the eccentric wheel assembly and the driver and reducing driver force loss.

[0029] The present application can realize that the fascia massage device can adjust the radial size of the connection center of the adjustment link and the rotation center of the driver in both the working state and the non-working state, so that the connection center of the adjustment link is close to or away from the rotation center of the driver, thereby realizing the eccentric radial size change, so as to achieve the purpose of adjusting the movement depth of the massage part and adapt to the different massage needs of the user. Since the depth of the skin fascia layer in different parts is different, the massage depth required when acting on different areas is also different. Therefore, the technical solution of the present application can adjust this space size, meet the needs of massage depth adjustment, and is very flexible and convenient.

[0051] Referring to Figures 1 to 17, the present application provides a specific embodiment of a fascia massage device, which includes a driver, a transmission assembly, and a massage element. In a specific embodiment, the driver shown is a drive motor 100. The drive motor 100 and the transmission assembly are both disposed in a housing 900. The housing 900 includes a first shell 901 and a second shell 902. The housing also includes an electrically connected PCBA board 904 and a battery 905. The housing 900 is provided with a user-operable button 903 connected to the PCBA board 904. The drive motor is also connected to the PCBA board 904 and the battery 905. The user can operate the fascia massage device through the button 903 to start and stop. In a specific embodiment, the massage element includes a piston head 906 that can act on the human body to produce a massage effect. The piston head 906 can act as a massage vibration output terminal to act on the human body to achieve a massage function. Furthermore, a protective cover 907 and a shock-absorbing soft rubber 908 can be added to the piston head 906 to improve massage comfort. A charging interface 9041 exposed to the housing may be provided on the PCBA board 904 , and the battery 905 may be a disposable battery or a rechargeable battery, and may also be powered by directly connecting to the mains.

[0052] Specifically, the transmission assembly includes an adjusting connecting rod 300, an eccentric wheel 200, a sliding member 400, and a transmission connecting rod 500. The output shaft 110 of the driving motor 100 is connected to the eccentric wheel 200 to drive the eccentric wheel 200 to rotate. Specifically, the upper part of the output shaft 110 of the driving motor 100 is inserted into the eccentric wheel 200 and fixedly connected thereto. Specifically, a cross-section can be provided on the upper part of the output shaft 110, and a socket with a matching cross-section can be provided at the lower connection of the eccentric wheel 200, so that the output shaft 110 and the eccentric wheel 200 rotate synchronously.

[0053] The eccentric wheel 200 is provided with a transversely disposed sliding groove 201. The sliding member 400 is disposed within the eccentric wheel 200 and is capable of relative movement along the sliding groove 201. The sliding member 400 can move transversely relative to the eccentric wheel 200 within the sliding groove 201, while the relative positions of the sliding member 400 and the eccentric wheel 200 remain unchanged in the longitudinal direction. Specifically, a first linkage shaft 402 is provided at the upper end of the sliding member 400, and a second linkage shaft 9061 is provided on the massage member 906. One end 501 of the transmission connecting rod is sleeved on the first linkage shaft 402 via a bearing 420, while the other end 503 of the transmission connecting rod is sleeved on the second linkage shaft 9061 via a bearing 510. Typically, the first linkage shaft 402 and the output shaft 110 are not coaxial. Therefore, when the eccentric wheel rotates, the sliding member 400 drives the transmission connecting rod 500 to move back and forth in the radial direction. A central bridge 502 is provided between one end 501 and the other end 503 of the transmission link. The bridge 502 is configured as a stepped transition structure, with two connected sections at different heights, resulting in a more compact structure. One end of the transmission link 500 is connected to the sliding member 400 for relative rotation, while the other end is connected to the massage member 906 for relative rotation.

[0054] The transmission assembly further includes an adjustment link 300. The output shaft 110 of the drive motor 100 is a hollow shaft. One end of the adjustment link 300 is inserted into the hollow shaft 110 and can move axially relative to the hollow shaft 110. The other end of the adjustment link 300 is inserted into the sliding member 400 and can move axially relative to the sliding member 400. The transmission assembly also includes a latch 410. The adjustment link 300 passes through the eccentric wheel 200 and is inserted into the sliding member 400. The sliding member 400 is provided with an inclined hole 401. The latch 410 passes through the inclined hole 401 and is fixedly connected to the end of the adjustment link 300 inserted into the sliding member 400.

[0055] The inclined hole 401 extends transversely through the sliding member 400, and the direction of extension intersects with the direction in which the sliding slot 201 is opened. The latch 410 is inserted perpendicularly to the direction in which the sliding slot 201 is opened. In a specific embodiment, the transverse direction of the inclined hole 401 is perpendicular to the direction in which the sliding slot 201 is opened, that is, the latch 410 is inserted perpendicularly to the direction in which the sliding slot 201 is opened. The inclined hole 401 extends transversely through the sliding member 400, and the direction of extension intersects with the direction in which the sliding slot 201 is opened. A cross-section taken along a plane perpendicular to the direction of extension has a long groove-like cross-section, and the centerline of the long groove intersects with the axis of the adjusting link 300. At the same time, the axis of the adjusting link 300 is parallel to or overlaps with the axis of the output shaft of the drive motor 100. When the adjustment link 300 moves longitudinally relative to the slider 400, the latch 410 fixedly connected to one end of the adjustment link 300 moves back and forth along the inclined direction of the inclined hole 401. Therefore, the latch 410 moves in an inclined direction intersecting the axis of the adjustment link 300, with both transverse and longitudinal components. This generates a driving force on the slider 400 with both transverse and longitudinal components. Furthermore, because the slider 400 can only move transversely within the sliding groove 201 and cannot move longitudinally relative to the eccentric 200, the slider 400 moves transversely along the sliding groove 201 under the driving force. That is, when the adjustment link 300 moves longitudinally (ascending / descending), the latch 410 and the slider's inclined hole 401 generate a tangential force, causing the slider 400 to move radially within the eccentric 200 relative to the output shaft center of the drive motor 100. By changing the rotation radius of the sliding member 400 and the center of the output shaft of the driving motor 100, the movement range of the massage member 906 can be adjusted.

[0056] The longitudinal and transverse directions are only for the purpose of clarity and convenience of description and are not intended to be limiting. Generally, the longitudinal direction is consistent with the axis of the output shaft of the drive motor 100, and the transverse direction is consistent with the radial direction perpendicular to the axis.

[0057] A shock absorber is provided in the sliding groove 201 and is located between the sliding member 400 and the eccentric wheel 200. The shock absorber is a shock absorber spring 220 that is laterally disposed between the outer wall of the sliding member 400 and the inner wall of the sliding groove 201. Specifically, spring grooves 404 and 203 may be provided on opposite sides of the sliding member 400 and the eccentric wheel 200 to accommodate the shock absorber spring 220 for greater stability.

[0058] A positioning pin 210 is provided above the sliding member 400 and is fixed longitudinally relative to the eccentric wheel 200. Specifically, a transverse pin slot 403 is provided on the upper portion of the sliding member 400. One or two pin slots 403 may be provided. In a specific embodiment, one pin slot 403 is provided at each shoulder of the upper portion of the sliding member 400. The transverse orientation of the pin slot 403 aligns with the direction in which the sliding slot 201 is opened. A transverse positioning hole 202 is provided on the eccentric wheel 200. The positioning pin 210 is inserted into the positioning hole 202. The positioning pin 210 passes through the pin slot 403 in the direction in which it opens and presses against the pin slot 403, thereby preventing the sliding member 400 from moving longitudinally relative to the eccentric wheel 200.

[0059] Furthermore, the fascia massage device also includes an adjustment assembly, which includes a first adjustment knob 610. The first adjustment knob 610 is connected to one end of the adjustment link 300 via a bearing. The adjustment link 300 and the first adjustment knob 610 are fixed relative to each other in the longitudinal direction. The adjustment link 300 can rotate relative to the first adjustment knob 610. The first adjustment knob 610 is relatively fixed in the circumferential direction and adjustable in the axial direction. The first adjustment knob 610 can be displaced relative to the eccentric wheel 200 in the longitudinal direction. The adjustment assembly also includes a second adjustment knob 620. The second adjustment knob 620 and the first adjustment knob 610 are threaded together, allowing the first adjustment knob 610 to be displaced relative to each other in the longitudinal direction. The user can adjust the massage vibration stroke through the second adjustment knob 620. A limit structure is provided on the first adjustment knob 610, limiting the first adjustment knob 610 to only move up and down along the center of the drive motor 100. Specifically, the limiting structure on the first adjusting knob 610 is a positioning protrusion 611 set on the outer periphery of the first adjusting knob 610, and a corresponding matching positioning groove is set on the shell. The two cooperate to make the first adjusting knob 610 fixed in the circumferential direction relative to the shell and not rotate, that is, the first adjusting knob 610 is limited to move up and down only along the center of the drive motor 100.

[0060] Specifically, one end of the adjusting link 300 is inserted into the hollow shaft 110 of the driving motor, and is inserted into the inner ring of the bearing through the driving motor, and is connected to the first adjusting knob 610 through a bearing, and an adjusting link 300 screw is provided to achieve axial positioning and fixation with the inner ring of the bearing, and the outer ring of the bearing is fixedly connected to the first adjusting knob 610.

[0061] The second adjusting knob 620 is mounted on the housing and can be exposed from the housing for the user to adjust the operation. The user adjusts the massage stroke by rotating the second adjusting knob 620. Specifically, since the second adjusting knob 620 is threadedly matched with the first adjusting knob 610 and the first adjusting knob 610 can only move up and down along the axial direction but cannot be rotated, when the second adjusting knob 620 is rotated, it can drive the first adjusting knob 610 to adjust the axial up and down displacement. Since the first adjusting knob 610 and the adjusting link 300 are relatively fixed in the axial position through the connection of the bearing, when the first adjusting knob 610 moves up and down, it drives the adjusting link 300 to move up and down. Since the other end of the adjusting link 300 is in the sliding member 400, It is connected by a latch 410, and the latch 410 can slide in the inclined hole 401. Therefore, when the adjusting link 300 moves longitudinally relative to the sliding member 400, the latch 410 fixedly connected to one end of the adjusting link 300 moves back and forth along the inclined direction of the inclined hole 401. The movement direction of the latch 410 is the inclined direction intersecting with the axis of the adjusting link 300, and has components in both the transverse and longitudinal directions. Therefore, a driving force with both transverse and longitudinal components is generated on the sliding member 400. At the same time, because the sliding member 400 can only move transversely in the sliding groove 201, the sliding member 400 cannot move longitudinally relative to the eccentric wheel 200. Therefore, the sliding member 400 moves transversely along the sliding groove 201 under the driving force. That is, the up and down movement of the adjusting link 300 drives the pin 410 to move along the inclined hole 401, and has a horizontal and vertical relative movement component relative to the sliding member 400. The pin 410 generates horizontal and vertical tangential components relative to the inclined hole 401, that is, it generates a horizontal shear force on the sliding member 400, causing the sliding member 400 to move horizontally relative to the eccentric wheel 200 in the sliding groove 201, that is, the sliding member 400 makes radial movement along the center of the driving motor in the eccentric wheel 200, thereby changing the rotation radius size of the sliding member 400 and the center of the driving motor, thereby realizing the adjustment of the massage movement amplitude.

[0062] The above description is only a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto. Any equivalent transformation based on the technical solution of the present application falls within the protection scope of the present application.
