Description

The present invention includes a linear drive vibration mechanism such as a pump or a massager or a mechanism corresponding to a rotary motor in a device including the same, and an alternating current applied to a magnet shaft as a drive shaft and an induction coil fixed to the case. The shaft is reciprocated in the axial direction due to the fluctuation of the magnetic field magnetic flux generated by the current, and the case in which these mechanisms are incorporated vibrates, or the shaft is combined with a pump mechanism or the like, or the shaft is connected as an external mechanism. The present invention relates to a linear drive vibration device that linearly drives a pump or the like, and can be used to generate power if used in reverse.

In the conventional linear vibration device, the drive output is insufficient when compared with the output of an induction rotary motor or the like. When trying to obtain the same output as a rotary motor, the shape of the magnet or coil becomes large and heavy. Furthermore, when a high output is required as a power generation device, it is necessary to further increase the efficiency. By increasing the efficiency of these vibration devices beyond that of rotary motors, the driving force increases and can be used as a substitute for rotary motors. And an AC power generation system can be constructed. In the conventional mechanism, the bobbin-shaped induction coil is fixedly inserted into the center of the shaft where the variable magnetic field magnetic flux generated in the inner diameter portion by the amplified alternating current of the low frequency such as voice and frequency transmitter is inserted in the ring. The shaft is moved to the left and right by attracting and repelling the magnetic field magnetic flux of the magnet. However, in the conventional linear vibration mechanism, the magnetic flux does not sufficiently reflect and react to the magnetic flux generated in the induction coil on average. In addition, the system that vibrates left and right using the magnet magnetic flux that faces the alternating magnetic field magnetic flux on the top and bottom of the induction coil can extract a large drive output, but if the output is increased, the magnet surface will hit the coil surface and generate abnormal noise or damage the device. It became the cause of. When driven at a higher frequency, the amplitude decreases and the swinging fan mechanism linked to the shaft operation reduces the operation in proportion to the amplitude. Therefore, the cooling effect cannot be exhibited, and the magnetic flux rises due to the temperature rise of the magnet. A negative chain of rise and magnetic flux degradation, and no performance degradation or damage.

Conventionally, an electric vibration product close to this type has been disclosed or partially patented for a sensory acoustic vibration device, a vibrator, various power generation sensor devices, and a drive device, but is not well known as a practical product. In either case, the induction coil surface and the magnet surface are attracted and repelled, or the magnetic flux magnetic field fluctuation between the shaft magnet inserted in the coil ring is utilized. In addition, there is a mechanism that uses a mechanical leaf spring for the repulsion mechanism, so it is necessary to consider the life and noise is generated. Similar patents include the following published patents and patents.

Application No. Japanese Patent Application No. 2011-64941 Multifunctional Vibration Device Application No. Special Table No. 200252185 Application No. Japanese Patent Application No. 2005-118898 Reciprocating linear device The structure disclosed in JP-T-20011185 and JP-A-2005-118898 responds with minute driving, but when the driving output becomes large, the output is limited and the magnet hits the coil surface, causing abnormal noise and breakage, and is not practical.

The conventional synchronous vibration device is not a problem because it is a small output when used in a sensory acoustic synchronous vibration device or a human body massage vibrator, but when used as a drive device such as a pump or a generator function, high power generation capacity is required, It was necessary to operate linearly with the driving force, and the output was insufficient when compared with the same driving output of the rotary motor. In view of the above problems, an object of the present invention is to invent a new structure of a vibrator, to improve the efficiency of a magnetic induction circuit mechanism of a conventional linear vibration driving device, and to develop it in various application products.

In order to solve the above-mentioned problems, the linear drive vibration device according to the present invention has a gap slightly wider than the induction coil ring located in the central shaft of the case left and right bearing ring and is vertically magnetized. The first ring magnet with a coil width is inserted and bonded in a magnetic flux repulsion state with a gap on the left and right sides of the shaft, and the outer ring magnet on the shaft reacts to the magnetic pole of the induction coil surface from the inner diameter of the coil ring. A second ring magnet, which is larger and smaller than the outer diameter of the coil, is magnetized on the first magnet and fixed with an adhesive or the like, supported by bearings at both case ends at the stroke distance position, and a second magnet magnetic field on the shaft. A rebound ring magnet that repels magnetic flux is arranged and fixed on the bearing or case side with an inner diameter that freely penetrates the shaft. Coupling and a pump device or the like in the axial coupling by extending the shaft further to the outside of the case as an integral device as vessels, windmills, incorporated like various sensors such as generators and seismometers in reverse use linked like a water wheel.

In the vibration device according to the second aspect of the present invention, the induction coil and the shaft magnet unit constituting the plurality of vibration mechanisms are arranged radially and uniformly in the center portion of the case, the cylinders including the induction coils are arranged, and the gap in the center of the linder is arranged. The unit is equipped with a cooling fan motor mechanism or device, and discs that are opposed to each other with a stroke distance sandwiched between cylinders are arranged on the left and right. The discs are made of aluminum or heat-resistant resin that also serves as a cooling fan. The shaft of each mechanism part is fixed with fastening elements, such as a screw, with the thin disk discs made. The induction coil of a plurality of vibration units has a mechanism capable of increasing / decreasing the driving force by distributing the alternating current through a selection circuit that applies single or multiple alternating currents. A reciprocating shaft is provided outside the center of the left and right discs, and a bearing is disposed on the case side at a position where a stroke distance is taken to support the shaft. In response to an alternating current applied to the induction coil, the shaft is linked to the movement of the fixed shaft connected to the fixed shaft of each unit. The rebound magnets are placed and secured on the sides of the left and right cases at the same position as the magnet group fixed to the disk on the surface, and repel the magnet magnetic field magnetic flux of the fixed disk, so the center of the shaft between each bearing is always a coil ring when there is no signal. It can be centered. The arrangement of the repulsion magnet and its magnetic flux are set according to the situation of the non-driving device.

According to a third aspect of the present invention, in the vibration device according to the first and second aspects, when the device is driven at a high frequency, the device must be cooled when the output is increased. Therefore, the current that applies the voice or drive frequency amplification current to the induction coil is branched and converted into direct current by an electronic rectifier provided in the case, and a constant current is distributed to the direct current motor. A mechanism or device for driving inside the device for cooling is provided in the case or at the end of the case.

As described above, according to the first aspect of the present invention, the magnetic pole shape that uses the variable magnetic field magnetic flux of the induction coil by the magnet-shaped structure fixed to the shaft is compared with the conventional magnet structure, and the magnetic flux generated on the upper and lower surfaces of the coil. Since both sides of the magnetic flux generated in the inner diameter portion can be used as effective magnetic fields at the same time, the coil fluctuation magnetic flux can be used with high efficiency on average, so that the vibration device can output a drive output higher than that of the rotary motor. By applying this mechanism, it is possible to produce pumps and vibrators with a simple structure and high driving force, and various sensors such as generators, seismometers and vibrometers can be connected in reverse.

According to the second aspect of the present invention, the discs having the function of cooling fan with the mechanism shafts fixed at the stroke distances on both sides of the cylinder incorporating the plurality of vibration mechanisms according to the first aspect are arranged on the left and right sides, and the left and right outer sides in the center. Since a reciprocating shaft is arranged toward and supported by a case bearing, a large driving force can be produced, and if necessary, each vibration unit can be selectively operated, leading to energy saving. Further, a fan motor device or mechanism is provided in the center clearance of the cylinder so that fan cooling can be operated properly, so that the temperature of the device does not rise and the performance is stabilized and the life and reliability are increased.

According to a third aspect of the invention, in the linear drive vibration device according to the first and second aspects, when the current is amplified at a high frequency of the alternating AC signal or the audio signal, the amplitude becomes small, and the cooling operation by the reciprocating operation of the shaft magnet. However, the magnetic flux is reduced and the coil is deteriorated and damaged. However, a DC motor fan is placed inside the device and its power supply is branched from the AC induction coil current. By converting and distributing the drive voltage to the motor with a substantially constant voltage, the fan can operate stably, and the cooling capacity can be maintained constant regardless of the frequency, resulting in a highly reliable device with long performance and long life.

A shaft joint is shown at the tip of the one-side shaft and is connected to a pump as a non-driving body, a shaft of a water turbine or a wind turbine during power generation, or used as a generator or various sensors. Embodiment FIG. 8 is a cross-sectional view of the entire side surface of the multiple complex vibration drive device of the second aspect of the present invention, in which a shaft joint 22 is shown as in FIG. Embodiment FIG. 1 and FIG. 8 are also fan mechanism diagrams that can be substituted for a DC motor. 3, 4 and 5 show the state of fluctuation of the magnetic poles of the coil and magnet in the vibration drive device shaft operation, and no current is applied to the induction coil 4 when there is no signal, so that the shaft magnet 5 remains neutral in FIG. However, when an alternating current is applied to the induction coil 4, positive and negative magnetic poles are formed at the left and right ends 4 of the coil ring. The state is roughly divided into left and right regions at the center of the coil. The demagnetization goes to the center, and the opposite magnetic pole region is reached when it exceeds. On the other hand, the magnetic fluxes at the end faces of both coil rings become weaker toward the outer circumference, but are not opposite to each other. The present invention makes it possible to generate a driving magnetic flux 1.5-2 times that of the conventional structure by simultaneously sensitizing these two regions to the shaft magnet magnetic field magnetic flux. To use the magnetic pole magnetic flux at both ends in the surface area, there was a drawback such as a magnet colliding with the induction coil surface, but by using the magnetic pole magnetic flux of the inner ring of the coil at the same time, the opposite area in the end point area with respect to the acceleration motion of the shaft The magnetic pole magnetic flux is braked and the working force is reduced and the driving force is doubled. FIG. 5 shows both magnet magnetic fluxes in which a current is applied to the induction coil 4, an S pole magnetic flux is formed on the right ring, an N pole magnetic flux is formed on the left ring, and a gap 23 slightly longer than the induction coil ring width on the shaft side is arranged. Reacts and the shaft in the same polarity state moves to the right and operates until the case repulsive magnet magnetic field repels the second magnet outer magnetic field. On the other hand, since the shaft left magnet magnetic field is opposite to the opposite pole, the attracting shaft is moved to the right. At that time, the first magnet outer N-pole is bonded and fixed simultaneously with the second magnet S-pole and is sensitive to the surface magnetic flux S. However, the first magnet middle S pole is braked to the magnetic pole magnetic flux S pole at the other end of the coil. The process of FIG. 3 is repeated and the shaft is smoothly driven to reciprocate. 8, FIG. 9 and FIG. 10 show a side sectional view, a front partial sectional view and a shaft fixing disk partial view of a vibration driving device of a multiple composite mechanism.
