Description

Technical Field

[0001] This invention relates to the field of massage equipment technology, and in particular to a power output device for massage equipment and a massage equipment. Background Technology

[0002] Currently, most massage devices on the market, such as fascia guns or massage hammers, only offer a single percussion mode, resulting in a limited range of massage options and reduced user experience and effectiveness. Conversely, massage products with multiple modes tend to have more complex structures and higher costs, further discouraging consumers. For example, Chinese patent CN109864877A discloses a medical massage hammer comprising a hammer body, a first hammer head, a second hammer head, a first hammer rod, and a second hammer rod. The first hammer head is connected to the second hammer head via the hammer body, and the hammer body is threaded to the first hammer rod, with the second hammer rod located at the bottom of the first hammer rod. Clearly, this massage hammer only offers a percussion mode and lacks other massage options, resulting in limited usability and poor massage effectiveness. Summary of the Invention

[0003] To address the aforementioned technical problems in the prior art, this invention provides a power output device and a massage device for use in massage equipment, which can realize percussion massage mode and oscillating massage mode, thereby increasing the functionality of the massage equipment and meeting various user needs.

[0004] This invention provides a power output device for a massage device, comprising:

[0005] An actuation assembly includes a drive element and a transmission element connected to the output shaft of the drive element;

[0006] The first power output component includes a first power arm and a sliding component connected to each other. The sliding component is connected to the massage head of the massage device. The first power arm is connected to the transmission component and is used to drive the sliding component to perform linear reciprocating motion when the transmission component rotates in a first direction along the output axis.

[0007] The second power output component includes a second power arm and a swing assembly connected to each other. The swing assembly is connected to the massage head, and the second power arm is connected to the transmission component. When the transmission component rotates along the output axis in a second direction, it drives the swing assembly to perform a circumferential oscillating motion; wherein the first direction and the second direction are opposite directions. This structure enables both percussion massage and swing massage modes, increasing the functionality of the massage device and meeting various user needs.

[0008] In some embodiments, the transmission component includes a transmission shaft and a first one-way rotating body sleeved outside the transmission shaft. The first one-way rotating body is connected to the first power arm and is used to drive the first power arm to perform linear reciprocating motion when the transmission shaft rotates in a first direction, and to stop the first power arm from moving when the transmission shaft rotates in a second direction. This structure enables stable movement of the first power arm, and its design is reasonable and provides stable transmission.

[0009] In some embodiments, the transmission component includes a transmission shaft and a second unidirectional rotating body sleeved outside the transmission shaft. The second unidirectional rotating body is connected to the second power arm and is used to drive the second power arm to perform a circumferential yaw motion when the transmission shaft rotates in a second direction, and to stop the second power arm from moving when the transmission shaft rotates in a first direction. This structure enables stable movement of the second power arm, and its design is reasonable and provides stable transmission.

[0010] In some embodiments, the sliding assembly includes a sliding sleeve connected to the massage head, and the oscillating assembly includes an oscillating sleeve connected to the sliding sleeve. The oscillating sleeve is connected to the massage head via the sliding sleeve to drive the massage head to perform a circumferential oscillating motion. The connection relationship between the oscillating sleeve and the sliding sleeve allows for a more compact and rational structure of the power output device, and also helps to improve structural stability.

[0011] In some embodiments, the second power arm is provided with a mounting groove, and the swing assembly further includes a rotatable positioning member rotatably disposed in the mounting groove. The rotatable positioning member is connected to the swing sleeve and is used to drive the swing sleeve and the sliding sleeve to perform circumferential swinging motion when the second power arm moves with the transmission member. By setting the rotatable positioning member, the swing sleeve can perform circumferential swinging motion under the action of the second power arm, making the structural design of the swing assembly reasonable.

[0012] In some embodiments, the rotatable positioning member has a groove, and the swing sleeve has a protruding post extending into the groove, so that when the sliding sleeve makes a linear reciprocating motion, the protruding post of the swing sleeve slides within the groove. Through the cooperation of the groove and the protruding post, when the sliding sleeve makes a linear reciprocating motion, the sliding sleeve drives the swing sleeve to make a synchronous linear reciprocating motion, without driving the rotatable positioning member and the second power arm to make a linear reciprocating motion.

[0013] In some embodiments, the first power output assembly further includes a first eccentric wheel sleeved outside the transmission member. The first eccentric wheel is connected to a first end of the first power arm, and a second end of the first power arm is connected to the sliding sleeve. A positioning sleeve is sleeved over the sliding assembly. The transmission member drives the first power arm and the sliding assembly to perform linear reciprocating motion along the axial direction of the positioning sleeve via the first eccentric wheel. The first eccentric wheel and the positioning sleeve enable the first power arm and the sliding assembly to perform stable linear reciprocating motion, and the above structural design is reasonable and the transmission is stable.

[0014] In some embodiments, the sliding assembly further includes a bearing sleeve and a first bearing. The first bearing is sleeved on the sliding sleeve, and the bearing sleeve is sleeved outside the first bearing. The sliding sleeve is connected to the second end of the first power arm through the first bearing and the bearing sleeve, so that the bearing sleeve and the sliding sleeve can perform linear reciprocating motion under the drive of the first power arm. The above structural design is reasonable, and the structural layout is more compact.

[0015] In some embodiments, the second power output assembly further includes a second eccentric wheel and a positioning shaft. The second eccentric wheel is sleeved outside the transmission member and connected to a first end of the second power arm. The second end of the second power arm is connected to the swing sleeve. The positioning shaft passes between the first and second ends of the second power arm, allowing the second power arm to swing around the positioning shaft. The second eccentric wheel and positioning shaft enable the second power arm and swing sleeve to stably perform circumferential oscillating motion, and the above structural design is reasonable and the transmission is stable.

[0016] This invention also provides a massage device, including the aforementioned power output device for a massage device. The above structure enables both percussion massage and oscillating massage modes, increasing the functionality of the massage device and meeting various user needs.

[0017] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows: The present invention can drive the massage head to perform linear reciprocating motion through the first power output component to realize the percussion massage mode of the massage device, and can also drive the massage head to perform circumferential oscillating motion through the second power output component to realize the oscillating massage mode of the massage device. The above-mentioned percussion massage mode and oscillating massage mode can be performed independently, and the switching between the percussion massage mode and the oscillating massage mode can be realized by controlling the direction of the output shaft of the drive component, so as to improve the massage effect and enhance the user experience. Furthermore, the percussion massage mode and the oscillating massage mode can be realized by setting only one drive component, which can effectively reduce the manufacturing cost of the device and improve the market competitiveness of the product.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] This invention provides a power output device for a massage device, which can be a fascia gun, a handheld massage hammer, a massage cushion, a massage chair, or other massage products. This application does not specifically limit the type of massage device. The massage device only needs to have a massage head, and the massage head can achieve multiple massage modes through different movement methods.

[0030] like Figures 1 to 4 As shown, the power output device includes an actuation assembly 1, a first power output assembly 2, and a second power output assembly 6. The actuation assembly 1 includes a drive member 11 and a transmission member 12 connected to the output shaft of the drive member 11. The first power output assembly 2 includes a first power arm 3 and a sliding assembly 4 connected together. The sliding assembly 4 is connected to the massage head 5 of the massage device, and the first power arm 3 is connected to the transmission member 12. When the transmission member 12 rotates along the output shaft in a first direction, it drives the sliding assembly 4 to perform linear reciprocating motion. The second power output assembly 6 includes a second power arm 7 and a swing assembly 8 connected together. The swing assembly 8 is connected to the massage head 5, and the second power arm 7 is connected to the transmission member 12. When the transmission member 12 rotates along the output shaft in a second direction, it drives the swing assembly 8 to perform circumferential oscillation motion; wherein the first direction and the second direction are opposite directions.

[0031] Figure 1 The arrow shown in the figure indicates the direction of motion of the massage head 5 when it makes a linear reciprocating motion. At this time, the massage device using the above-mentioned power output device is in the percussion massage mode. Figure 2 The arrow shown indicates the direction of motion of the massage head 5 when it performs a circumferential oscillating motion. At this time, the massage device using the aforementioned power output device is in oscillating massage mode. When the output shaft rotates in the first direction, the transmission member 12 will drive the sliding component 4 to perform linear reciprocating motion via the first power arm 3; when the output shaft rotates in the second direction, the transmission member 12 will drive the oscillating component 8 to perform a circumferential oscillating motion via the second power arm 7. Therefore, the switching control between the percussion massage mode and the oscillating massage mode can be achieved by controlling the direction of the output shaft.

[0032] Optionally, the aforementioned drive unit 11 can be configured as a motor. The movement of the motor in the first direction can be understood as the motor output shaft rotating forward, and the movement of the motor in the second direction can be understood as the motor output shaft rotating in reverse, so as to adjust the massage mode by controlling the forward and reverse rotation of the motor output shaft.

[0033] The above structure ensures that whether the motor rotates forward or backward, one of the first power output component 2 and the second power output component 6 will move while the other stops moving. By setting a single motor, two different massage modes are achieved: a percussion massage mode and a swing massage mode.

[0034] Optionally, the aforementioned actuation component 1 may further include a mechanism support 18, with the drive component 11 detachably mounted on the mechanism support 18.

[0035] Optionally, the transmission component 12 may have a first end and a second end that are arranged opposite to each other. The first power output component 2 may be arranged at the first end of the transmission component 12, and the second power output component 6 may be arranged at the second end of the transmission component 12, so as to avoid mutual interference between the movements of the first power output component 2 and the second power output component 6 and to ensure movement stability.

[0036] Optionally, the sliding component 4 can be fixedly connected to the massage head 5, and the massage head 5 can perform linear reciprocating motion under the drive of the sliding component 4.

[0037] Optionally, the massage head 5 may have an annular connecting portion connected to the sliding component 4, and the sliding component 4 may have an annular groove sleeved outside the annular connecting portion.

[0038] Optionally, the swing assembly 8 can be connected to the massage head 5 via the sliding assembly 4, and the swing center of the swing assembly 8 can be the axis of the massage head 5, so that the swing assembly 8 can perform circumferential swinging motion along the axis of the massage head 5. Here, the axis of the massage head 5 can be understood as the axis of the annular connecting part.

[0039] Optionally, the swing angle of the swing component 8 can be in the range of -60 degrees to 60 degrees, and the swing component 8 can swing along the axis of the massage head 5.

[0040] This invention enables the massage head 5 to perform linear reciprocating motion via the first power output component 2, achieving a percussion massage mode. It also enables the massage head 5 to perform circumferential oscillating motion via the second power output component 6, achieving a swing massage mode. The percussion and swing massage modes can be performed independently, and switching between them can be achieved by controlling the direction of the output shaft of the drive component 11, thereby improving the massage effect and enhancing the user experience. Furthermore, since both percussion and swing massage modes can be achieved with only one drive component 11, the manufacturing cost of the device can be effectively reduced, improving the product's market competitiveness.

[0041] In some embodiments, such as Figures 1 to 4As shown, the transmission component 12 includes a transmission shaft 13 and a first one-way rotating body 14 sleeved outside the transmission shaft 13. The first one-way rotating body 14 is connected to the first power arm 3 and is used to drive the first power arm 3 to perform linear reciprocating motion when the transmission shaft 13 rotates in the first direction, and to stop the first power arm 3 when the transmission shaft 13 rotates in the second direction. The above structure enables the first power arm 3 to move stably, and the structural design is reasonable and the transmission is stable.

[0042] By setting the first unidirectional rotating body 14, the first power arm 3 can be limited to move when the transmission shaft 13 moves in the first direction, and stop moving when the transmission shaft 13 moves in the second direction, thus realizing the percussion massage mode and the swing massage mode by setting a single driving component 11.

[0043] Optionally, the first one-way rotating body 14 can be specifically a one-way bearing. A one-way bearing is a type of bearing that can rotate freely in one direction and is locked in the other. The one-way bearing enables the first power arm 3 to move when the drive shaft 13 rotates in the first direction, and stops the first power arm 3 when the drive shaft 13 rotates in the second direction. Of course, the first one-way rotating body 14 can also be other structures that can only perform unidirectional movement, and this application does not specifically limit it.

[0044] Optionally, such as Figure 3 As shown, the transmission component 12 may include a transmission belt 16 and a transmission wheel 17. The output shaft of the drive component 11 is connected to the transmission wheel 17. The transmission wheel 17 and the transmission belt 16 are connected in a transmission connection. The transmission belt 16 and the transmission shaft 13 are connected so that the first power arm 3 is moved by the transmission belt 16 in sequence through the transmission wheel 17, the transmission belt 16 and the transmission shaft 13.

[0045] In some embodiments, such as Figures 1 to 4 As shown, the transmission component 12 includes a transmission shaft 13 and a second one-way rotating body 15 sleeved outside the transmission shaft 13. The second one-way rotating body 15 is connected to the second power arm 7 and is used to drive the second power arm 7 to perform a circumferential yaw motion when the transmission shaft 13 rotates in the second direction, and to stop the second power arm 7 from moving when the transmission shaft 13 rotates in the first direction. The above structure enables the second power arm 7 to move stably, and the structural design is reasonable and the transmission is stable.

[0046] By setting the second unidirectional rotating body 15, the second power arm 7 can be limited to move when the transmission shaft 13 moves in the second direction, and stop moving when the transmission shaft 13 moves in the first direction. This allows the percussion massage mode and the swing massage mode to be realized by setting a single driving component 11.

[0047] Optionally, the second one-way rotating body 15 can be specifically a one-way bearing. A one-way bearing is a type of bearing that can rotate freely in one direction and is locked in the other. The one-way bearing enables the drive shaft 13 to rotate in the second direction, driving the second power arm 7 to move, and stops the second power arm 7 when the drive shaft 13 rotates in the first direction. Of course, the aforementioned second one-way rotating body 15 can also be other structures capable of only unidirectional movement; this application does not specifically limit its application in this regard.

[0048] Optionally, the first unidirectional rotating body 14 and the second unidirectional rotating body 15 can be connected to the two ends of the transmission shaft 13 respectively, so as to make the structural design layout reasonable and avoid the movement of the first power output component 2 and the second power output component 6 interfering with each other.

[0049] Optionally, the drive shaft 13 can be rotatably mounted on the mechanism support 18, and the connection between the mechanism support 18 and the drive shaft 13 can be located between the two ends of the drive shaft 13.

[0050] In some embodiments, such as Figures 1 to 4 As shown, the sliding assembly 4 includes a sliding sleeve 41 connected to the massage head 5, and the swing assembly 8 includes a swing sleeve 81 connected to the sliding sleeve 41. The swing sleeve 81 is connected to the massage head 5 through the sliding sleeve 41 to drive the massage head 5 to perform a circumferential swinging motion. The connection relationship between the swing sleeve 81 and the sliding sleeve 41 makes the structure of the power output device more compact and reasonable, and also helps to improve the structural stability.

[0051] Optionally, the swing sleeve 81 may have a bushing structure, and the end of the sliding sleeve 41 facing the swing sleeve 81 may be formed with a shaft. The shaft can be inserted into the bushing structure to connect with the bushing structure. When the transmission member 12 rotates in the second direction with the output axis, the swing sleeve 81 will make a circumferential swing motion along the axis of the shaft.

[0052] Optionally, the end of the sliding sleeve 41 facing away from the swing sleeve 81 may form the aforementioned annular groove, and the axis of the annular groove and the axis of the shaft may be collinear.

[0053] In some embodiments, such as Figures 1 to 6 As shown, the second power arm 7 is provided with a mounting groove 71, and the swing assembly 8 also includes a rotatable positioning member 83 rotatably disposed within the mounting groove 71. The rotatable positioning member 83 is connected to the swing sleeve 81 and is used to drive the swing sleeve 81 and the sliding sleeve 41 to perform circumferential swinging motion when the second power arm 7 moves with the transmission member 12. By setting the rotatable positioning member 83, the swing sleeve 81 can perform circumferential swinging motion under the action of the second power arm 7, making the structural design of the swing assembly 8 reasonable. Figure 5 and Figure 6 The arrow shown in the figure indicates the circumferential oscillation direction of the oscillating component 8.

[0054] Optionally, the two ends of the rotatable positioning member 83 may be formed with rotating shafts, and the rotating shafts located at both ends of the rotatable positioning member 83 may be inserted into the groove wall of the mounting groove 71 respectively, so as to be rotatably disposed in the mounting groove 71.

[0055] Optionally, the axial direction of the rotation axis of the aforementioned rotatable positioning member 83 may be perpendicular to the axial direction of the transmission shaft 13.

[0056] In some embodiments, such as Figures 1 to 6 As shown, the rotatable positioning member 83 has a groove 84, and the swing sleeve 81 has a protruding post 82 that extends into the groove 84, so that when the sliding sleeve 41 makes a linear reciprocating motion, the protruding post 82 of the swing sleeve 81 will slide within the groove 84. Through the cooperation of the groove 84 and the protruding post 82, when the sliding sleeve 41 makes a linear reciprocating motion, the sliding sleeve 41 can drive the swing sleeve 81 to make a linear reciprocating motion synchronously, without driving the rotatable positioning member 83 and the second power arm 7 to make a linear reciprocating motion.

[0057] Optionally, the length direction of the aforementioned groove 84 may be the same as the axis of rotation of the rotatable positioning member 83. The outer wall of the protrusion 82 may fit against the outer wall of the groove 84, so that the rotatable positioning member 83 can cause the swing sleeve 81 to make circumferential swinging motion under the drive of the second power arm 7 through the interaction of the protrusion 82 and the groove 84.

[0058] Optionally, the aforementioned protrusion 82 can be a cylinder, and the axial direction of the rotation axis of the rotatable positioning member 83 can be perpendicular to the axial direction of the protrusion 82.

[0059] Alternatively, the protrusion 82 may be formed by extending outward along the radial direction of the bushing structure.

[0060] In some embodiments, such as Figures 1 to 4 As shown, the first power output assembly 2 also includes a first eccentric wheel 21 sleeved outside the transmission member 12. The first eccentric wheel 21 is connected to the first end of the first power arm 3, and the second end of the first power arm 3 is connected to the sliding sleeve 41. The sliding assembly 4 is sleeved with a positioning sleeve 22. The transmission member 12 drives the first power arm 3 and the sliding assembly 4 to perform linear reciprocating motion along the axial direction of the positioning sleeve 22 through the first eccentric wheel 21. The first eccentric wheel 21 and the positioning sleeve 22 enable the first power arm 3 and the sliding assembly 4 to perform stable linear reciprocating motion, and the above structural design is reasonable and the transmission is stable.

[0061] Optionally, the first eccentric wheel 21 is sleeved outside the first one-way rotating body 14 so that when the transmission member 12 moves in the first direction, the first eccentric wheel 21 can make circular motion through the first one-way rotating body 14.

[0062] Optionally, the positioning sleeve 22 can be understood as a structure fixedly installed inside the housing of the massage device, and the positioning sleeve 22 will not move relative to the housing of the massage device.

[0063] In some embodiments, such as Figures 1 to 4 As shown, the sliding assembly 4 also includes a bearing sleeve 42 and a first bearing 43. The first bearing 43 is fitted onto the sliding sleeve 41, and the bearing sleeve 42 is fitted onto the outside of the first bearing 43. The sliding sleeve 41 is connected to the second end of the first power arm 3 through the first bearing 43 and the bearing sleeve 42, so that the bearing sleeve 42 and the sliding sleeve 41 can perform linear reciprocating motion under the drive of the first power arm 3. By setting the first bearing 43, the bearing sleeve 42 can be prevented from moving when the sliding sleeve 41 swings with the swing sleeve 81, so that the percussion massage mode and the swing massage mode can be performed independently. The above structural design is reasonable and the structural layout is more compact.

[0064] Optionally, the bearing sleeve 42 can be connected to the second end of the first power arm 3 via a positioning pin 44, so that the bearing sleeve 42 and the sliding sleeve 41 can be driven to perform linear reciprocating motion by the first power arm 3.

[0065] In some embodiments, such as Figures 1 to 4 As shown, the second power output assembly 6 also includes a second eccentric wheel 61 and a positioning shaft 62. The second eccentric wheel 61 is sleeved on the outside of the transmission member 12 and is connected to the first end of the second power arm 7. The second end of the second power arm 7 is connected to the swing sleeve 81. The positioning shaft 62 passes between the first and second ends of the second power arm 7, so that the second power arm 7 swings around the positioning shaft 62. The second eccentric wheel 61 and the positioning shaft 62 enable the second power arm 7 and the swing sleeve 81 to stably perform circumferential oscillating motion. The above structural design is reasonable and the transmission is stable.

[0066] Optionally, the second power arm 7 may have a rectangular groove, and the eccentric shaft of the second eccentric wheel 61 may be slidably disposed in the rectangular groove.

[0067] Optionally, the second eccentric wheel 61 is sleeved outside the second one-way rotating body 15 so that when the transmission member 12 moves in the second direction, the second eccentric wheel 61 can make a circular motion through the second one-way rotating body 15.

[0068] Optionally, the positioning shaft 62 is rotatably mounted on the mechanism support 18, and the rotation center of the second power arm 7 is the axis of the positioning shaft 62.

[0069] The working principle of the power take-off device is explained below:

[0070] When the output shaft of the drive component 11 drives the transmission component 12 to rotate in the first direction, such as when the motor rotates forward, the drive component 11 drives the transmission wheel 17 to rotate, and the transmission wheel 17 drives the transmission shaft 13 to rotate through the transmission belt 16. The transmission shaft 13 drives the first one-way rotating body 14 to rotate. At this time, the second one-way rotating body 15 does not rotate, and the first one-way rotating body 14 drives the first eccentric wheel 21 to perform circular motion. The first eccentric wheel 21 pulls the sliding component 4 through the first power arm 3. The sliding component 4 is restricted by the positioning sleeve 22 and can only perform linear reciprocating motion. In this way, the circular motion is converted into linear reciprocating motion, thereby realizing the percussion massage mode.

[0071] When the output shaft of the drive component 11 drives the transmission component 12 to rotate in the second direction, if the motor reverses, the drive component 11 drives the transmission wheel 17 to rotate, and the transmission wheel 17 drives the transmission shaft 13 to rotate through the transmission belt 16. The transmission shaft 13 drives the second one-way rotating body 15 to rotate. At this time, the first one-way rotating body 14 does not rotate, and the second one-way rotating body 15 drives the second eccentric wheel 61 to make a circular motion. Restricted by the positioning shaft 62, one end of the second power arm 7 will make a circumferential swing motion under the drive of the second eccentric wheel 61, and the other end will also make a circumferential swing motion. The swing sleeve 81 is installed in the rotatable positioning component 83. The swing sleeve 81 makes a circumferential swing motion with the axis of the sliding sleeve 41 as the rotation center. The swing sleeve 81 is also connected to the sliding sleeve 41 and the massage head 5. Thus, the massage head 5 can make a circumferential swing motion with the swing sleeve 81 to realize the swing massage mode.

[0072] This invention also provides a massage device. For example... Figure 7 As shown, the massage device includes the aforementioned power output device for massage. The massage device using this power output device can drive the massage head 5 to perform linear reciprocating motion via the first power output component 2 to achieve a percussion massage mode. It can also drive the massage head 5 to perform circumferential oscillating motion via the second power output component 6 to achieve a swing massage mode. The percussion and swing massage modes can be performed independently, and switching between them can be achieved by controlling the direction of the output shaft of the drive component 11, thereby improving the massage effect and enhancing the user experience. Furthermore, since both percussion and swing massage modes can be achieved with only one drive component 11, the manufacturing cost of the device can be effectively reduced, improving the product's market competitiveness.

[0073] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its scope and spirit, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
