Meanwhile, according to the installation position of the motor, eccentric block and the like in the massage device, it is possible to affect the vibration device to efficiently exert the vibration function. SUMMARY

[0003] In order to overcome the shortcomings and deficiencies of the prior art, the present application provides a vibration device and a massage device comprising the vibration device.

[0004] The vibration device and the massage device comprising the vibration device provided by the present application adopt the following technical scheme:

[0005] A vibration device, comprising a motor, a speed reduction mechanism and a rotating body, the output of the motor drives the rotating body to rotate after being reduced by the speed reduction mechanism, the rotating body is an eccentric structure and is internally provided with a cavity, and the motor and the speed reduction mechanism are both built-in in the internal cavity of the rotating body.

[0006] By adopting the above technical scheme, the structure of the vibration device with motor, eccentric block and the like is miniaturized, so that the vibration device becomes compact and integrated, which can not only realize various vibration functions required, but also is easy to install in a relatively small space, realizing the miniaturization and lightness of the whole.

[0007] Optionally, the speed reduction mechanism is a speed reduction gear set.

[0008] Optionally, the rotating body is a round ball with two ends being flattened, and the flattened end surface is parallel to the rotating direction of the rotating body.

[0009] Optionally, the round ball is composed of two half ball blocks.

[0010] Optionally, the position of the eccentric block can be adjusted.

[0011] Optionally, the speed reduction mechanism is a speed reduction gear set, the speed reduction gear set is composed of three gears, including a driving gear matched with the output shaft of the motor, a first driven gear meshed with the driving gear, and a second driven gear meshed with the first driven gear; a support shaft is arranged through the ball, the ball can rotate around the support shaft; the second driven gear is connected with the support shaft, and the motor is fixed on the ball; when the ball rotates, the motor and the speed reduction gear set rotate together with the ball.

[0012] Optionally, a support shaft is arranged through the ball, and the ball can rotate around the support shaft; the motor is fixed at one end of the support shaft, and the output shaft of the motor is fixed to the ball through a speed reduction mechanism; when the motor drives the ball to rotate, the motor, the speed reduction gear set, and the support shaft remain relatively static.

[0013] The application also provides a massage device comprising the vibration device, including the rod body, the inside of which is provided with a cavity, and the vibration device is located in the internal cavity of the rod body.

[0014] Optionally, the vibration device is located at one end of the rod body.

[0015] Optionally, the rod body comprises a carrier and a cover body; the lower edge of the cover body is matched with the upper edge of the carrier, and a cavity for accommodating the vibration device is formed therebetween; and the rotating body is matched with the top of the carrier through the support shaft, so that the rod body is vibrated by the vibration of the vibration device.

[0016] In summary, the application has at least one of the following beneficial technical effects:

[0017] 1. The vibration device has a high-speed rotating ball (the center of gravity of the ball is offset from the axis), which generates centrifugal force in different directions by high-speed rotation of the eccentric ball, and drives the rod body to move in multiple directions. Therefore, the vibration device and the massage device provided with the same can realize various functions, miniaturization, and efficiently exert the vibration function; in addition, the device can output ultra-high rotation speed and centrifugal force under the condition of small reduction ratio of the speed reduction box, which can meet the requirements of strong vibration and large vibration amplitude, and high frequency and large force of stretching and contraction, and can meet the massage needs of users in multiple ways;

[0018] 2. The massage device drives the eccentric ball to rotate at high speed by the motor through the speed reduction box, generates centrifugal force, and the centrifugal force generated by the high-speed rotation of the eccentric ball is distributed in the normal direction of the center of mass of the ball. With the eccentric ball rotating to different angles, centrifugal force in different directions is generated. The centrifugal force in the same direction as the length direction of the rod body generates stretching and contraction movement, which can form a point impact massage effect similar to a fascia gun. The centrifugal force perpendicular to or at a certain angle to the rod body drives the rod body to vibrate in multiple directions, which is suitable for large-area massage of local skin and muscles. Due to the high-speed rotation of the eccentric ball, the device has the technical effect of superposition of vibration and stretching and contraction. Attached Figure Description

[0028] The present application will be further described in detail below with reference to Figures 1-7.

[0029] This application discloses a vibration device. (See attached document.) Figure 1A , 1BAs shown, the vibration device 1 comprises a motor 2, a gear reduction set 3, and an eccentric ball 5 with an eccentric block 4. The eccentric ball 5 is hollow and has a support shaft 6 passing through it. The motor 2 and the gear reduction set 3 are built inside the hollow structure of the eccentric ball 5, and the gear reduction set 3 is connected to the support shaft 6. The output shaft of the motor 2 drives the driving gear 3-1 of the gear reduction set 3, which drives the eccentric ball 5 to rotate after being decelerated by the gear reduction set 3. In a preferred embodiment, the eccentric ball 5 is composed of two half ball blocks (left ball block 5-1 and right ball block 5-2). The eccentric block 4 causes the eccentric ball 5 to generate uneven centrifugal force in the circumferential direction, thereby causing the eccentric ball 5 to vibrate.

[0030] In other embodiments, the eccentric ball 5 can use other eccentric structures capable of axial rotation to generate a vibration effect, such as a disc, a cuboid, a polyhedron, or even an irregularly shaped rotating body.

[0031] In an alternative embodiment, referring to the accompanying drawings Figure 1A 、 1B As shown, the gear reduction set 3 is composed of three gears, including the driving gear 3-1 cooperating with the output shaft of the motor 2, the first-stage driven gear 3-2 meshing with the driving gear 3-1, and the second-stage driven gear 3-3 meshing with the first-stage driven gear 3-2.

[0032] Referring to the accompanying drawings Figure 2A 、 2B As shown, the last-stage driven gear 3-3 of the gear reduction set 3 drives the support shaft 6 of the eccentric ball 5, thereby driving the eccentric ball 5 to rotate. The motor 2 is fixed on the eccentric ball 5, and when the eccentric ball 5 rotates, the motor 2 and the gear reduction set 3 rotate together with the eccentric ball 5.

[0033] As another alternative, referring to the accompanying drawings Figure 3A 、 3B As shown, the motor 2 is fixed on one end of the support shaft 6 of the eccentric ball 5, the output shaft of the motor 2 drives the gear reduction set 3, and the second-stage driven gear 3-3 of the gear reduction set 3 is fixed to the eccentric ball 5, thereby driving the eccentric ball 5 to rotate. The eccentric ball 5 can rotate around its support shaft 6. Thus, when the eccentric ball 5 rotates, the motor 2, the gear reduction set 3, and the support shaft 6 remain stationary.

[0034] Referring to the accompanying drawings Figure 4 The present application also relates to a massage device comprising the aforementioned vibration device. The massage device 13 comprises a rod body 14, and the rod body 14 has a cavity built inside for installing the vibration device 1. The vibration device 1 can be located at any part of the rod body 14, for example, in the accompanying drawings Figure 4 In the accompanying drawings, the vibration device 1 is located at the end of the rod body 14, which can be the front end or the rear end.

[0035] Specifically, the rod 14 includes a carrier and a cover; the lower edge of the cover is fitted with the upper edge of the carrier, and a cavity is formed between the two to accommodate the vibration device 1. The sphere 5 is fitted with the top of the carrier through the support shaft 6, so that the rod 14 vibrates through the vibration of the vibration device 1.

[0036] The mounting structure of the vibration device 1 when placed inside the carrier 10 of other massage equipment is similar to the mounting structure when placed inside the aforementioned rod 14. (See attached document.) Figure 5 With appendix Figure 6 As shown, the sphere 5 can be fastened to its support shaft 6, or it can rotate around the support shaft 6. When the sphere 5 is fastened to the support shaft 6, the support shaft 6 is rotatably disposed in a rotation groove on the inner wall of the cavity of the carrier 10. When the sphere 5 and the support shaft 6 rotate relative to each other, the support shaft 6 is fixed in the rotation groove on the inner wall of the cavity of the carrier 10.

[0037] Reference Appendix Figure 5 When sphere 5 is in circular motion, the eccentric block 4 moves to each different position, and the centrifugal force is along the tangent of the sphere's trajectory. This centrifugal force can be decomposed into two components: one perpendicular to the carrier 10 and one along the carrier 10. The component perpendicular to the carrier 10 causes the carrier 10 to sway left and right, while the component along the carrier 10 causes the carrier 10 to extend and retract.

[0038] When the eccentric block 4 is in position, the centrifugal force has only the component F1 perpendicular to the direction of the carrier 10, and the component F2 along the length of the carrier 10 is 0; at this time, the amplitude of the carrier 10 swinging to the right is the largest, and no extension or contraction motion is generated along the carrier 10.

[0039] As the eccentric block 4 moves from position 10 to position 20, the centrifugal force can be decomposed into a component force F1 perpendicular to the direction of carrier 10 and a component force F2 along the length of carrier 10, with F1 gradually decreasing and F2 gradually increasing. Correspondingly, during this process, the amplitude of the rightward sway of carrier 10 gradually decreases, while the amplitude of the downward extension and contraction of carrier 10 begins to appear and gradually increases.

[0040] When in the specified position, the two component forces F1 and F2 are equal in magnitude. In this position, the force that causes the carrier 10 to sway to the right is the same as the force that causes the carrier 10 to sway downward.

[0041] As the eccentric block 4 moves from position 1 to position 2, F1 gradually decreases to less than F2. During this process, the force causing the carrier 10 to sway to the right further weakens, while the force acting downwards along the carrier 10 further increases.

[0042] When the eccentric block 4 is in position 10, F1 decreases to 0, and the centrifugal force is entirely along the direction of the carrier 10. In this position, there is only a force that causes the carrier 10 to move downwards.

[0043] When the eccentric block 4 moves from position to position, the component F1 of the centrifugal force F gradually increases from 0, and the component F2 gradually decreases. In this process, the force that makes the carrier 10 sway to the left begins to appear and gradually increases, while the force that makes the carrier 10 move downward gradually decreases, but F2 is still greater than F1, so the effect after superposition is that the force that makes the carrier 10 move downward is still stronger than the force that makes the carrier 10 sway to the left.

[0044] Until the eccentric block 4 moves to position, the two components F1 and F2 are equal in size. The force that makes the carrier 10 move downward is the same as the moment that makes the carrier 10 sway to the left.

[0045] When the eccentric block 4 moves from position to position, F2 begins to gradually decrease than F1. In this process, the moment that makes the carrier 10 sway to the left is gradually greater than the moment that makes the carrier 10 move downward.

[0046] Until the eccentric block 4 moves to position, F2 decreases to 0, and the centrifugal force becomes completely perpendicular to the direction of the carrier 10. At this time, the superimposed moment completely makes the carrier 10 sway to the left.

[0047] When the eccentric block 4 moves from position to position, the centrifugal force F can be decomposed into the component F1 to the left and the component F2 upward, the component F1 gradually decreases, and the component F2 gradually increases, but F1 is still greater than F2. Therefore, in this process, the moment that makes the carrier 10 sway to the left and the moment that makes the carrier 10 move upward are superimposed, but the moment that makes the carrier 10 sway to the left is greater than the moment that makes the carrier 10 move upward.

[0048] When the eccentric block 4 moves to position, the components F1 and F2 are equal in size, and after superposition, the moment that makes the carrier 10 sway to the left is equal to the moment that makes the carrier 10 move upward.

[0049] When the eccentric block 4 moves from position to position, the component F1 that makes the carrier 10 sway to the left is gradually less than the component F2 that makes the carrier 10 move upward, and after superposition, there is not only the moment that makes the carrier 10 sway to the left, but also the moment that makes the carrier 10 move upward, and the moment that makes the carrier 10 move upward is greater.

[0050] When the eccentric block 4 moves to position, the component F1 that makes the carrier 10 sway to the left decreases to zero, and the component F2 that makes the carrier 10 move upward reaches the maximum, and the moment after superposition completely makes the carrier 10 move upward.

[0051] When the eccentric block 4 moves from position to position, the component F1 that makes the carrier 10 sway to the right begins to appear and gradually increases, and the component F2 that makes the carrier 10 move upward begins to gradually decrease, but F2 is still greater than F1, so in this process, the moment that makes the carrier 10 sway to the right and the moment that makes the carrier 10 move upward are superimposed, and the moment that makes the carrier 10 move upward is greater.

[0052] When the eccentric block 4 moves to the position, the component force F1 that causes the carrier 10 to sway to the right is equal in magnitude to the component force F2 that causes the carrier 10 to move upward. After being superimposed, the torque that causes the carrier 10 to sway to the right is equal to the torque that causes the carrier 10 to move upward.

[0053] When the eccentric block 4 moves from position 10 to position 2, the component force F2 that causes the carrier 10 to move upward gradually becomes less than the component force F1 that causes the carrier 10 to sway to the right. The torque that causes the carrier 10 to move upward is superimposed on the torque that causes the carrier 10 to sway to the right, resulting in a larger torque that causes the carrier 10 to sway to the right. This continues until the eccentric block 4 moves to position 3, at which point the component force F2 that causes the carrier 10 to move upward decreases to 0, and the force that causes the carrier 10 to sway to the right reaches its maximum value.

[0054] Since the sphere 5 acts directly on the support shaft 6, and the support shaft 6 is fixed to the carrier 10, the force on the carrier 10 is the same as that of the centrifugal force described above. As the eccentric block 4 rotates, the force on the carrier 10 changes continuously, thus causing it to sway.

[0055] Appendix Figure 7 The centrifugal force analysis shown is performed without considering the weight of the eccentric block and external forces such as the user's grip force. However, in actual use, the weight of the eccentric block and the magnitude and position of the user's grip force will have a certain impact on the forces acting on the carrier 10.

[0056] Therefore, in actual use, the vibration of the carrier 10 or other massage equipment will generate different torques depending on the position of the user's hand, the magnitude and direction of the hand grip, thus causing different shaking and bringing different massage experiences to the user.

[0057] In an optional embodiment, the user can adjust the position of the eccentric block 4 relative to the sphere 5 using a slider or knob on the housing of the massage device 13, thereby adjusting the magnitude of the centrifugal force generated by the rotation of the sphere 5 and thus changing the intensity of the shaking. When the user needs to adjust the position of the sphere 5 to change the intensity of the shaking during use, the distance of the eccentric sphere 5 from the center of the entire product can be changed by pulling and pulling the slide rail to adjust its length. The rolling of the steel balls inside the slide rail can diffuse the force in all directions, ensuring the overall horizontal and vertical stability of the massage device 13.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
