As is well known, a vibration sensor for detecting a predetermined vibration is one of a series of methods for minimizing the impact on a production facility by preventing a failure of one part or a sudden stop of operation in a production facility system by constant automation. After detecting the normal vibration range of the vibration signal generated by the various rotating bodies added to such equipment, it is possible to predict the condition and life of the equipment, or to recognize the abnormal shaking of the building structure to recognize the deformation of the structure itself. It is applied to a variety of applications, such as to measure the vibration characteristics generated during exercise, such as walking or running in all directions, and then to calculate the calories burned in connection with the physical information of the exerciser.

In general, such a vibration sensor is attached to a predetermined vibrating body and converts the mechanical vibration component of the vibrating body into an electrical signal in addition to converting the amount of charge generated by the piezoelectric material inside the sensor into various electric signals. By virtue of the method, vibration sensors capable of detecting vibrations are provided correspondingly, and such vibration sensors are generally configured to include a part for driving them and a basic signal processing system for processing the detected vibration signals.

As shown in this, the vibration sensor using the magnetic properties of the present invention is formed in a substantially ring shape and a pair of extension portions (D) having a predetermined length in a downward direction from a certain portion of the left and right side is formed, The surface is formed in the ring of the first terminal member 110 and the first terminal member 110, which is configured to maintain a predetermined distance (D1) and the outer peripheral surface of the upper surface and the predetermined opening portion is formed a pair of extensions A second terminal member 130 having another pair of extension portions E formed in a lower direction and intersecting at a right angle with (D), and being positioned on the second terminal member 130 and the first terminal member ( Steel ball 112 for maintaining the upper surface and the separation gap (D1), the hollow portion is formed inside the cylindrical, so that the first terminal member 110 and the second terminal member 130 can be inserted and fixed Body in which the coupling member 142 is formed in a predetermined portion thereof Part 140, the distance adjusting screw 160 is helically coupled to the nut portion 144 formed on the inner bottom surface of the coupling member 142, and the magnetic 150 seated on the distance adjusting screw 160 above It is characterized by including the configuration.

The distance adjusting screw 160 adjusts the distance (D2) between the magnetic 150 and the second terminal member 130 according to the coupling adjustment with the nut portion 144, the steel ball 112 according to the adjustment It is configured to adjust the magnetic force applied to the). The distance adjusting screw 160 has a spiral 162 is formed on the outer circumferential surface for coupling with the nut portion 144.

The steel balls 112 are always located on the central axis of the second terminal member 130 (that is, on the center line of the magnetic body) according to the magnetic force line distribution property of the magnetic 150, and the steel balls 112 when a predetermined impact is applied from the outside. Is configured to move in the horizontal direction from the state positioned on the second terminal member 130 and to be in electrical conduction in contact with the first terminal member 110, after which the steel ball 112 is the original state by the magnetic property Will return.

The first terminal member 110 and the second terminal member 130 is made of an electrically conductive material, the coupling member 142 and the body portion 140 is made of an insulating material. In addition, the distance adjusting screw 160 is preferably made of a conductive material so that the magnetic 150 positioned on the upper surface thereof is fixed, but the structure of the magnetic 150 is sufficiently fixable, for example, a groove portion is formed and the groove portion thereof. It may be composed of a non-conducting material that forms a structure that can be secured to.

The operation of the vibration sensor using the magnetic properties of the present invention configured as described above will be described with reference to FIGS. 1 to 3.

First, the vibration sensor 100 using the magnetic properties of the present invention is the steel sphere 112 located on the second terminal member 130 in the state that the impact is not applied from the outside is always located magnetic 150 It is located on the central axis by the magnetic field distribution of, the magnetic strength of the magnetic force 150 for such steel ball 112 is adjusted by the distance control by the distance adjusting screw 160. That is, the steel balls 112 located on the second terminal member 130 should be able to move smoothly by providing the most appropriate magnetic strength.

In such a state, when a shock of a certain intensity is applied to the vibration sensor from the outside, the steel balls 112 are horizontally in front, rear, left and right directions in close contact with the second terminal member 130. Direction and then return to the central axis by the magnetic force of the magnetic 150, when the steel ball 112 is moved on the second terminal member 130, the steel ball 112 is the first terminal member The contact state 110 is maintained instantaneously and is electrically switched on by contact with the first and second terminal members 110 and 130. Of course, when the steel ball 112 is returned to its original state, the steel ball 112 is switched off.

The switching on state may detect whether vibration due to electrical contact.

This will be described by applying to a pedometer counting the number of steps of a person according to an embodiment of the present invention. The drawing for the pedometer is not shown.

First, the pair of extension portions D and E of the first terminal member 110 and the second terminal member 130 of the vibration sensor 100 of the present invention are connected to the counter of the pedometer. Then, since the steel ball 112 maintains a predetermined interval spaced apart from the first terminal member 110, the steel ball 112 exhibits an electrical short circuit state.

When the user wearing the pedometer walks or runs from the above state, each time the impact occurs, the steel ball 112 is moved in one horizontal direction on the second terminal member 130 to contact the first terminal member 110. At the same time, it is converted into an electrically conducting state so that the counter part connected to the extension parts D and E is driven. Of course, immediately after contact with the first terminal member 110, the steel ball 112 is located on the central axis of the magnetic 150 to return. By such operation the counter of the pedometer is incremented.

At this time, it is natural that the magnetic strength of the magnetic 150 applied to the steel ball 112 should be sufficiently adjusted so that the steel ball can move in proportion to the impact applied to the pedometer. For example, if the magnetic force applied to the pedometer is not properly adjusted, the movement of the steel ball 112 does not occur even when walking or running. On the contrary, the distance between the magnetic 150 and the steel ball 112 If the magnetic strength is set so far away, the steel ball 112 can be easily moved even in a weak impact, it will not be able to provide a sufficient function as a pedometer.

Even if the described embodiments are protruding, they should not be individually understood from the technical idea or the prospect of the present invention, but should fall within the claims appended to the present invention.

As described above, according to the vibration sensor using the magnetic properties of the present invention, the impact / vibration is applied from the outside while the steel ball is constantly positioned on the center line of the predetermined contact terminal according to the magnetic field properties and magnetic strength of the magnetic Since the steel balls are simultaneously brought into contact with other contact terminals spaced apart from the contact terminals on the ground, it is possible to easily detect the vibration depending on the switching function by the electrical connection of such contact terminals, and furthermore, the steel balls are positioned by shock / vibration. Since it returns to the center line immediately after the change, there is an effect that can counter the continuously generated vibration.
