Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

The utility model provides a vibrating device based on elastic coupling possesses and has: a driving part including a motor and a first case for accommodating the motor; a vibrating part including a polarization mechanism to generate mechanical vibration and a second case to accommodate the polarization mechanism; wherein the motor has a first shaft, the polarization mechanism has a second shaft, and the first shaft and the second shaft are coupled by an elastic shaft so that the vibration part can freely swing when transmitting the rotational power. The utility model discloses an elastic shaft coupling connects vibration portion and drive division to improve the vibration effect of vibration portion.

The following further illustrates embodiments of the present invention by way of specific examples.

Referring to fig. 1 and 3, fig. 1 and 3 show one embodiment of the vibration device of the present invention. In this embodiment, the vibration device includes a driving portion and a vibration portion, the driving portion includes a motor 10 and a first housing 11 for accommodating the motor 10, the motor 10 is fixed in the first housing 11 by means of screws or the like; the vibrating section includes a polarization mechanism 30 to generate mechanical vibration and a second case 40 accommodating the polarization mechanism 30. Wherein, the power output end of the motor 10 is connected with a first shaft 12, the polarization mechanism 30 is provided with a second shaft 31, and the first shaft 12 and the second shaft 31 are connected through a cylindrical spring 20.

When the motor 10 in the driving portion is operated, the power is transmitted to the first shaft 12, the first shaft 12 transmits the power to the second shaft 31 through the cylindrical spring 20, and the polarization mechanism 30 is driven to generate eccentric vibration, thereby driving the vibration portion to vibrate as a whole. In this embodiment, the cylindrical spring 20 is used as the elastic shaft for transmitting power, in the process of transmitting power, because the cylindrical spring has good elasticity, the swing freedom is large, the swing amplitude is also large, the vibration effect of the vibration part can be effectively improved, meanwhile, the cylindrical spring has a good reset effect, after the vibration is finished, the vibration part can well return to the initial position, thereby the service life of the whole vibration device is prolonged, in addition, the cylindrical spring has good deformation characteristic, the cylindrical spring can adapt to the change of the vibration part through the self deformation bending, so that the vibration part is in the vibration process, and the vibration is not easy to reversely transmit the vibration to the driving part through the elastic shaft.

Specifically, cylindrical spring 20 adopts compact type spring, and at the in-process of transmission power, cylindrical spring 20's direction of motion is mainly at its radial swing, need not warp on its length direction, and cylindrical spring 20 adopts compact type spring structure, can effectually reduce its length direction's deformation to can not pull open between guarantee vibration portion and the drive division. Further, two ends of the cylindrical spring 20 are fixedly combined with the first shaft 12 and the second shaft 31, respectively, and the fixed combination may be welding, screwing, and the like. Because power transmission exists among the first shaft 12, the cylindrical spring 20 and the second shaft 31, certain swing also exists, and the cylindrical spring 20 can be prevented from being separated from the first shaft 12 and the second shaft 31 by adopting a fixed connection mode.

In the embodiment, the polarization mechanism 30 is located in the second casing 40, and the polarization mechanism 30 drives the second casing 40 to vibrate together during the vibration process. At this time, the second housing 40 performs the oscillating vibration with respect to the first housing 11, and in order to prevent the second housing 40 from interfering and colliding with the first housing 11 during the vibration, there is a certain interval between the first housing 11 and the second housing 40, which ensures that the second housing 40 does not interfere and collide with the first housing 11 when vibrating with the polarization mechanism 30.

Furthermore, the first shell 11 and the second shell 40 are connected through the third shell 21, so that the shell of the whole vibration device forms a whole, and thus, transmission components such as the cylindrical spring 20 and the like can be prevented from being exposed, the appearance is attractive, and meanwhile, foreign objects are prevented from entering the inside of the vibration device through a gap between the first shell 11 and the second shell 40. Here, it should be noted that the third shell 21 itself has certain flexibility, and the material thereof may be silica gel, elastic clinker, or other materials, and when the second shell 40 vibrates along with the polarization mechanism 30, the third shell 21 deforms correspondingly, so as to adapt to the vibration of the second shell 40, and avoid the transmission of a large amplitude of vibration to the first shell 11. In the present embodiment, the third shell 21 is mainly located outside the cylindrical spring 20, and has a space inside, and the space can be used for the cylindrical spring 20 to make certain swing.

Further, in the present embodiment, the polarization mechanism 30 includes a mute bearing 32 and eccentric portions 33 located on both sides of the mute bearing 32, the second shaft 31 is supported on the second housing 40 by the mute bearing 32, and the two eccentric portions 33 are disposed in phase. Therefore, in the vibrating process of the vibrating part, the vibration amplitude of the vibrating part in each direction is approximately the same, and a better vibrating effect can be obtained when the vibrating device is placed at will; in addition, the noise of the polarization mechanism 30 in the vibration process can be effectively reduced by positioning and supporting the second shaft 31 through the mute bearing 32.

Referring to fig. 2, the present invention further provides a vibration-type massage apparatus, which uses the vibration device provided in the above embodiment.

The vibrating massager further includes a control circuit 60 and an energy source, which may be the battery 50 or a power panel with a power cord. Preferably, in the local vibration type massager, the storage battery 50 is adopted as an energy source, and when the storage battery 50 is provided, the local vibration type massager does not need external power supply, can be moved for use, and is more convenient to use.

Specifically, in the local vibration type massager, the battery 50, the control circuit 60 and the motor 10 are integrally installed in the first housing 11, wherein the motor 10 is located at one end of the second housing 40 close to the massage head, the battery 50 is located at one end of the second housing 40 far away from the massage head, and the control circuit 60 is located between the battery 50 and the motor 10. Because the battery 50 has a heavy weight, the position of the overall center of gravity of the vibration massager can be changed by placing the battery at the end of the long handle far away from the massage head, so that the overall center of gravity of the massager inclines towards the long handle, and the user can conveniently hold the massager by hand. In addition, the control circuit 60 is disposed between the battery 50 and the motor 10, which means that the control circuit 60 is disposed at the middle position of the long handle, and when the control circuit 60 is disposed at the middle position of the long handle, the user can handle the long handle more conveniently.

Further, in the vibration massage apparatus, the first shell 11 and the second shell 40, i.e., the outer surface of the vibration massage apparatus, are further covered with a soft shell 70, and the first shell 11 and the second shell 40 are integrally mounted in the soft shell 70. The soft shell 70 is wrapped on the outer surfaces of the first shell 11 and the second shell 40, so that the hand-held hand feeling of a user is better, and meanwhile, a waterproof effect can be achieved.
