[0004] With the rapid development of society, people are increasingly concerned about the importance of physical health, and a large number of health products have been developed to improve sub-health conditions. Some products, such as mattresses, sofas, and massage chairs, now have internal vibrators. These vibrators contain a vibration motor that generates vibrations, providing a massage effect for those who sit on them. However, the vibration motors currently used in vibrators on the market often use pulleys and belts for transmission. The rotating shaft and eccentric weight are arranged coaxially with the drive pulley to transmit vibrations. This results in significant transmission losses, and after long-term use, the belt is prone to slippage due to tensioning, resulting in poor transmission stability. Furthermore, the coaxial arrangement of the motor, rotating shaft, and eccentric weight results in suboptimal vibration transmission, resulting in weak and unstable vibrations in the vibration motor. Consequently, the overall vibration stability and vibration effect of the vibrator need to be improved.

[0005] Therefore, how to improve the vibration stability of the vibration motor at least to a certain extent has become an urgent problem to be solved by those skilled in the art.

[0035] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0036] The purpose of this specific embodiment is to provide a vibration motor and a rhythm machine, a rhythm mattress, a rhythm sofa and a rhythm recliner including the vibration motor. The structure is simple, the transmission is stable and efficient, the rotating shaft and the motor can both output stable vibrations, and the overall vibration of the vibration motor is regular and stable. Compared with the existing technology, the vibration and massage effects are improved to a certain extent, which can relieve people's fatigue, promote people to quickly enter deep sleep, and improve human sub-health.

[0037] The following embodiments are described in detail with reference to the accompanying drawings. Furthermore, the embodiments described below do not limit the invention as set forth in the claims. Furthermore, the entire contents of the configurations shown in the following embodiments are not necessarily required to serve as solutions to the invention as set forth in the claims.

[0038] Please refer to Figures 1-6. A vibration motor provided in this embodiment includes a housing 10, a motor 3 arranged in the housing 10, a coupling 8 and a vibration assembly, the vibration assembly including a rotating shaft 4 and an eccentric block 5, the eccentric block 5 is connected to the rotating shaft 4, and the eccentric block 5 is eccentrically arranged relative to the central axis of the rotating shaft 4, that is, the central axis of the eccentric block 5 does not coincide with the central axis of the rotating shaft 4; the motor 3 is fixed to the inner wall of the housing 10, a bearing 6 is fixed on the inner wall of the housing 10, the outer ring of the bearing 6 is fixedly connected to the inner wall of the housing 10, the rotating shaft 4 penetrates into the bearing 6, the inner ring of the bearing 6 is rotatably connected to the rotating shaft 4, and the rotating shaft 4 is connected to the housing 10 through the bearing 6; at the same time, the rotating shaft 4 is transmission-connected to the power output shaft of the motor 3 through the coupling 8, and the rotating shaft 4 and the power output shaft are coaxially arranged, that is, the central axes of the two coincide, so that the rotating shaft 4 and the motor 3 can be arranged along the length direction of the housing 10. As shown in FIG1 , the housing 10 can be divided into two chambers along the length direction, a shaft chamber and a motor chamber. The shaft 4 is mounted in the shaft chamber via a bearing 6 , and the motor 3 is connected in the motor chamber.

[0039] When the motor 3 is started, the power output shaft outputs torque, which is transmitted through the coupling 8, the rotating shaft 4 rotates, and the eccentric mass 5 rotates synchronously, and generates centrifugal force, causing the rotating shaft 4 to vibrate; on the one hand, the rotating shaft 4 transmits the vibration to the rotating shaft cavity through the bearing 6, and the side shell 10 vibrates; on the other hand, the vibration is transmitted to the coaxially arranged power output shaft and the motor 3 through the rigid coupling 8, so that the motor 3 vibrates synchronously, and the motor 3 transmits the vibration to the motor cavity, and the side shell 10 also vibrates, then the entire shell 10 vibrates synchronously, rather than one side vibrating stronger and the other side vibrating weaker, and the overall vibration is regular and stable. The coupling 8 is used for transmission, and the rotating shaft 4 is coaxially arranged with the power output shaft of the motor 3. Compared with the belt transmission in the prior art, in which the rotating shaft 4 is parallel to the power shaft, the structure provided by this embodiment has the following advantages: on the one hand, the transmission is more stable and efficient, and there will be no transmission weakening or occasional interruption in long-term use, which can ensure the stable rotation of the rotating shaft 4, thereby ensuring the stable generation of vibration. From this point of view, the vibration intensity is guaranteed; on the other hand, when transmitting vibration, the coupling 8 can reduce vibration loss compared to the belt, and coaxial transmission is also better than parallel transmission that requires steering, and vibration transmission is more efficient, so that synchronous vibration is generated on both sides of the housing 10 without a large difference in strength. From this point of view, the vibration intensity output by the vibration motor provided by this embodiment through the housing 10 is higher, more stable, more uniform and regular; combining the two aspects of the discussion, on the whole, the vibration motor provided by this embodiment, the entire housing 10 can generate synchronous vibration, output stable, regular and intensity-guaranteed vibration, improve stability and vibration effect, can provide effective massage, relieve human fatigue, improve human sub-health or promote people to quickly enter deep sleep, and truly play a role in health. Another beneficial effect is that the vibration motor provided by this embodiment has a simpler structure and is easier to produce.

[0040] Furthermore, two vibration assemblies may be provided, and the two vibration assemblies may be arranged symmetrically with respect to the motor 3 at either end. The housing 10 is provided with two rotating shaft cavities, with the motor cavity located between the two rotating shaft cavities. Alternatively, a transmission shaft coaxially arranged with the power output shaft may be provided within the motor 3. The transmission shaft and the power output shaft are connected via a gear transmission and are arranged along the length of the motor 3. The transmission shaft is connected to the two vibration assemblies at both ends in a one-to-one correspondence, and each is connected to the corresponding rotating shaft 4 via a coupling 8. The same power output shaft drives the two vibration assemblies to vibrate synchronously and at the same frequency. Alternatively, the motor 3 may be configured as a dual-shaft motor as known in the art, with a power transmission shaft at each end, which can be connected to the two vibration assemblies in a one-to-one correspondence. With this configuration, the two sets of vibration assemblies can significantly enhance the intensity of the vibration emitted. Furthermore, the two sets of vibration assemblies are symmetrically arranged on either side of the motor 3. The transmission of the entire vibration motor is stable, with good vibration uniformity, regularity, and superior stability, providing a continuous and comfortable vibration sensation. Of course, after the vibration motor is electrically connected to the frequency modulator or controller, the vibration frequency and vibration intensity can be changed to meet the needs of different experiencers and different application scenarios.

[0041] The housing 10 may be composed of an upper housing 1 and a lower housing 2 that are interlocked with each other. Both the upper housing 1 and the lower housing 2 are provided with interlocking protrusions 12. The two interlocking protrusions 12 are aligned and can be connected by fasteners such as bolts. The housing 10 may also be provided with an inspection port for the motor 3 to enter and exit, and a lid 13 covering the inspection port. The lid 13 is connected to the housing 10 in an openable and closable manner. Through the inspection port, the components inside the housing 10 can be inspected without disassembling the upper housing 1 and the lower housing 2. The motor cavity may be provided with support ribs 23 protruding from the inner wall. The motor 3 is mounted in the housing 10 through the support ribs 23. In this way, the motor 3 does not directly contact the inner wall of the housing 10, forming a certain gap for gas flow, which is conducive to heat dissipation and has a good heat dissipation effect. The housing 10 may also be provided with heat dissipation holes 11 to further enhance the heat dissipation effect.

[0042] In the shaft cavity, side plates may be provided along the width direction of the shell 10, and bearing grooves 21 may be provided on the side plates, and bearings 6 are connected to the bearing grooves 21. As shown in FIG1 , two bearings 6 may be sleeved on a shaft 4 to more effectively transmit vibration. In a preferred embodiment, the ratio of the distance between the two bearings 6 to the size of the motor 3 in the same direction is not less than one-half, otherwise it is easy to affect the vibration intensity, and the specific size of the ratio can be specifically set according to needs or application scenarios. Preferably, the distance between the two bearings 6 is substantially consistent with or identical to the size of the motor 3 in the same direction, so that the length of the motor 3 is similar to that of the shaft 4, which can make the force acting on the left and right halves of the shell 10 more uniform, and can produce a better overall vibration effect.

[0043] In this embodiment, the eccentric block 5 is connected to the rotating shaft 4 and can be detachably connected. In this way, the eccentric block 5 and the rotating shaft 4 are split structures and can be disassembled and connected. When the two components are worn or fail, they can be replaced separately.

[0044] The eccentric block 5 may be provided with an arcuate fitting groove 51 that matches the outer wall of the rotating shaft 4. The rotating shaft 4 is at least partially embedded in the fitting groove 51, so that the eccentric block 5 and the rotating shaft 4 can be tightly fitted to ensure high efficiency and stability of the transmission.

[0045] In one embodiment, the eccentric block 5 can be in the shape of a long block, as shown in Figure 1. The length direction of the eccentric block 5 is set in the same direction as the axial direction of the rotating shaft 4, and the cross-section of the eccentric block 5 along the radial direction can be fan-shaped. In this way, the eccentric block 5 is a fan-shaped long column block. On the one hand, the centrifugal force generated on the rotating shaft 4 in its radial direction can change more slowly. On the other hand, the rotating shaft 4 is evenly stressed at various positions in the length direction, so that the overall vibration of the shell 10 is more uniform and the effect is better.

[0046] The eccentric mass 5 can be directly fastened to the rotating shaft 4 by fasteners, or a fixed disk 7 is provided on the rotating shaft 4, and the end of the eccentric mass 5 in the length direction is detachably connected to the fixed disk 7. The fixed disk 7 and the eccentric mass 5 can be connected by fastening screws or bolts. There can also be two fixed disks 7, one at each end of the eccentric mass 5, and the two fixed disks 7 are fastened to the two ends of the eccentric mass 5, respectively, to play a stable connection and clamping role on the eccentric mass 5, which can ensure the stability of the connection between the eccentric mass 5 and the rotating shaft 4, ensure smooth transmission, reduce transmission losses, and bring a comfortable vibration feeling to the experiencer. To ensure the vibration intensity, the ratio of the length of the eccentric mass 5 to the distance between the two bearings 6 is not less than one third. The closer the length of the eccentric mass 5 is to the distance between the two bearings 6, the more uniform the force on the rotating shaft 4 in the length direction, and the better the vibration effect of the housing 10.

[0047] As shown in Figure 2, in another embodiment, the eccentric mass 5 can be cylindrical and eccentrically mounted on the rotating shaft 4 to form an eccentric wheel. That is, the central axis of the eccentric mass 5 is parallel to the central axis of the rotating shaft 4 and spaced apart. The cylindrical eccentric mass 5 can be connected to the rotating shaft 4 via fasteners or can be an integral structure. The eccentric wheel structure also provides more stable vibration and is less susceptible to interference that may cause vibration of undesirable amplitude or frequency.

[0048] As shown in Figures 3 and 6, this embodiment also provides a rhythm machine, including a vibration plate 9 and a vibration motor as described in any of the above embodiments. The vibration plate 9 is connected to the vibration motor. Driven by the vibration motor, the vibration plate 9 can emit stable, regular, and strong vibrations. Therefore, the rhythm machine provided by this embodiment can output stable, regular, and intensity-guaranteed vibrations, improving vibration stability and vibration effects. When the vibration plate 9 of the rhythm machine is combined with a mattress, sofa, or recliner, it can provide a large area of ​​stable, regular, and strong vibrations, producing a good massage effect, relieving human fatigue, improving human sub-health or promoting people to quickly enter deep sleep, enhancing sleep quality, and truly playing a role in health benefits; and the vibration motor structure is simpler and easier to produce. The derivation process of this beneficial effect is basically the same as the derivation process of the beneficial effect brought about by the above-mentioned vibration motor, and will not be repeated here.

[0049] The vibration plate 9 can be a rectangular plate, as shown in FIG4 , or a plate of other shapes. When the length of the vibration plate 9 is long, the vibration motor can be set at the center of the vibration plate 9, and the two sides of the vibration plate 9 are symmetrically arranged relative to the vibration motor. Furthermore, as shown in FIG5 , the vibration plate 9 can be arranged as follows: along the length direction, the vibration plate 9 includes a connecting section 93 in the middle and wing blades 91 at both ends, the connecting section 93 connects the two wing blades 91, and the width of the connecting section 93 is less than the width of the two wing blades 91, and the entire vibration plate 9 is a symmetrical unfolded double-wing type; at the same time, the vibration motor is connected to the connecting section 93 and can be located at the center of the length direction of the vibration plate 9, and the axial direction of the rotating shaft 4 of the vibration motor is consistent with the direction of the vibration plate 9. With this arrangement, the wing blades 91 at both ends of the vibration plate 9 will be heavier than the connecting section 93 in the middle. At the same time, the axial direction and width direction of the rotating shaft 4 are consistent. Then, when the rotating shaft 4 rotates with the eccentric weight 5, the vibration plate 9 will not only vibrate under the action of centrifugal force, but also produce regular swings with the rotating shaft 4 as the center. The two wing blades 91 alternately descend and rise, and the displacement generated increases. The vibration plate 9 performs swinging vibrations, which significantly enhances the vibration sensation. Moreover, due to the stable transmission of the vibration motor and the stable and synchronous vibration transmission, the vibration effect is relatively uniform, and the directionality and periodicity of the vibration are relatively stable, which has a better massage effect on the human body. The vibration effect can penetrate deep into the inner layer of the body, promote blood circulation in the body, assist in the treatment of patients who have been bedridden for a long time, improve the sleep quality of patients with sleep disorders, and effectively supplement the amount of exercise for some people who are under great work pressure and lack exercise, improve their physical functions, and improve the sub-health of the human body.

[0050] Each wing blade 91 can be provided with a single fan-shaped wing blade 91, or it can be provided with two oblong wing blades 91 arranged along the width direction, as shown in FIG5 . The vibration plate 9 is configured in this shape to facilitate its swinging vibration under the action of centrifugal vibration. The vibration plate 9 can be cut and formed from a plate, or directly by injection molding.

[0051] The two wing blades 91 in the same wing blade 91 section are symmetrical along the length direction, and the two wing blades 91 are an integrated structure, and the transition between them is in the shape of a U-shaped groove 92. In this way, the transition is not easy to crack during vibration, thereby increasing the service life.

[0052] The vibration plate 9 can be configured as a fiberboard. Fiberboard has good toughness, a long service life, and good vibration effect. The vibration motor can be configured as a brushless motor. Brushless motors have high operating efficiency and high speed accuracy.

[0053] The connection between the vibration plate 9 and the vibration motor can be as shown in Figures 1 and 3. The outer wall of the housing 10 is provided with a support leg 22, which includes a connecting rod portion 221 and a pad portion 222. The pad portion 222 is located at the bottom of the connecting rod portion 221 and protrudes outward in the radial direction of the connecting rod portion 221. The pad portion 222 and the vibration plate 9 are both provided with fixing holes and are connected by bolts or screws.

[0054] Alternatively, as shown in Figure 6, a plate-shaped connecting plate 14 is provided on the outer wall of the shell 10, and the vibration plate 9 and the connecting plate 14 can be fitted and connected. The connecting plate 14 and the shell 10 can be an integral structure, and can be integrally molded by injection molding. Specifically, the shell 10 includes an upper shell 1 and a lower shell 2, and the upper shell 1 and the lower shell 2 are connected by bolts. Half of the connecting plate 14 is integrally provided on the upper shell 1, and half of the connecting plate 14 is integrally provided on the lower shell 2. When the upper shell 1 and the lower shell 2 are combined together, the two halves of the connecting plate 14 form the entire connecting plate 14. The vibration plate 9 can be connected to the connecting plate 14 by bolts; or a snap-in block and a snap-in groove can be provided on the connecting plate 14 and the vibration plate 9, respectively, and connected by a snap-in structure.

[0055] The vibrator also includes a controller electrically connected to the motor 3. This controller can control parameters such as the motor's rotational frequency. The controller is equipped with a wireless communication module for communicating with a mobile terminal. This allows the vibration motor to be controlled via the mobile terminal, allowing the user to adjust parameters such as vibration duration, intensity, and frequency. The wireless communication module can be configured as a Bluetooth module, a Wi-Fi module, a Zigbee module, or the like. The mobile terminal can be a mobile phone with an app installed, or a remote control.

[0056] This embodiment also provides a vibration mattress comprising a cushion body and the aforementioned vibration generator, with the vibration plate 9 of the vibration generator connected to the cushion body. With this arrangement, the vibration mattress provided by this embodiment can produce regular, stable, and guaranteed-intensity vibrations, improving vibration stability and effectiveness. This provides the user with a health-enhancing massage, producing a positive massage effect, alleviating fatigue, improving sub-health conditions, or promoting a rapid onset of deep sleep, truly achieving health benefits. Furthermore, the vibration motor structure is simpler and easier to manufacture. The derivation process for this beneficial effect is essentially the same as that for the aforementioned vibration motor, and will not be further elaborated here.

[0057] The cushion body is equipped with a waist area corresponding to the human waist and a leg area corresponding to the human calf, each with at least one vibrator. This arrangement places the vibration source in the two areas of the body most prone to fatigue and pain, providing a primary, strong massage to the waist and calf, while providing a less intense massage to other areas, better meeting actual needs and enhancing user comfort.

[0058] This embodiment also provides a rhythmic sofa, comprising a sofa cushion and a rhythmic device as described in the above embodiment. The vibration plate of the rhythmic device is connected to the sofa cushion. The rhythmic sofa provided by this embodiment can generate regular, stable, and guaranteed vibrations, improving vibration stability and vibration effect. It can provide a health-promoting massage to the user, producing a good massage effect, relieving fatigue, improving sub-health, or promoting sleep, truly achieving a health-promoting effect. The vibration motor structure is simpler and easier to produce. The derivation process of this beneficial effect is basically the same as the derivation process of the beneficial effect brought about by the vibration motor described above, and will not be repeated here.

[0059] This embodiment also provides a rhythmic recliner, comprising a seat cushion and a rhythmic device as described in the above embodiment, wherein the vibration plate of the rhythmic device is connected to the seat cushion.
