Abstract
An electromagnetic vibrating mechanism having a pair of electromagnetic sensors (30) disposed at both sides of a vibrating plate (20). Each of the electromagnetic sensors consists of one horseshoe-shaped solenoid (31) and two permanent magnets (40) disposed at the rim of the vibrating plate. The horseshoe-shaped solenoid (31) is provided with a first coil (32) and a second coil (33) at both ends thereof. In this way, an electromagnetic output having different polarity is achieved when the current is applied. Furthermore, the polarity can be duly changed by means of input of electric current in different directions. Besides, each of the permanent magnets (40) includes an upper magnet (41) and a lower magnet (42). The magnets are positioned in such a manner that the polarities thereof are different in lateral direction. Meanwhile, the horseshoe-shaped solenoid (31) is employed to create an up-and-down vibration.
Description
- The invention relates to an electromagnetic vibrating mechanism.
- The application of the induced magnetism by use of solenoid and permanent magnet for creating a vibrating mechanism has been disclosed in
US 3,830,099 ,US 7,141,029 ,US 5,693,990 andUS 4,788,968 (seeFIGS. 6 through 9 ). According toUS 3,830,099 ,US 7,141,029 andUS 5,693,990 , asolenoid 11 and a vibratingelement 10 are combined in a body while apermanent magnet 12 is disposed on abase 13 such that thesolenoid 11 is moved with thevibrating element 10. This configuration obviously does harm to the electronic circuit (not shown) of thesolenoid 11. Meanwhile, the service life thereof will be reduced as well. - According to
US 5,693,990 , thesolenoid 11 is has a fixed design. An upperpermanent magnet 14 is moved with avibrating element 10 while a lowerpermanent magnet 15 is unmovably fixed on abase 13. In other words, the gap between bothpermanent magnets solenoid 11 and the upperpermanent magnets vibrating element 10 rises. Therefore, the exercise intensity of the vibratingelement 10 can be increased. - A first object of the invention is to provide an electromagnetic vibrating mechanism having a solenoid fixed at a certain position and a permanent magnet unit movable with a vibrating plate for ensuring and prolonging the service life of electromagnetic sensors.
- This object is solved by the features of claim 1.
- Moreover, the connection line of the upper and lower magnets of the permanent magnets is aligned with the magnetic force midline e of the coils of the horseshoe-shaped solenoid such that both magnets are always subject to the magnetic force of the coils when the vibrating plate moves. In this way, the loss of the magnetic force can be effectively avoided.
- A pair of electromagnetic sensors is disposed at both sides of a vibrating plate. Each of the electromagnetic sensors consists of one horseshoe-shaped solenoid and two permanent magnets disposed at the rim of the vibrating plate. The horseshoe-shaped solenoid is provided with a first coil and a second coil at both ends thereof. In this way, an electromagnetic output having different polarity is achieved when the current is applied. Furthermore, the polarity can be duly changed by means of input of electric current in different directions. Besides, each of the permanent magnets includes an upper magnet and a lower magnet. The magnets are positioned in such a manner that the polarities thereof are different in lateral direction. Meanwhile, the horseshoe-shaped solenoid is employed to create an up-and-down vibration.

- Referring to
FIGS. 1 ,2 and 3 , a pair ofelectromagnetic sensors 30 is disposed at both sides of a vibratingplate 20. Each of theelectromagnetic sensors 30 consists of one horseshoe-shaped solenoid 31 and twopermanent magnets 40 disposed at the rim of thevibrating plate 20. The horseshoe-shaped solenoid 31 is provided with afirst coil 32 and asecond coil 33 at both ends thereof. In this way, an electromagnetic output having different polarity is achieved when the current is applied. Furthermore, the polarity can be duly changed by means of input of electric current in different directions. Besides, each of thepermanent magnets 40 includes anupper magnet 41 and alower magnet 42. Themagnets shaped solenoid 31 is employed to create an up-and-down vibration. - The connection line of the upper and
lower magnets permanent magnets 40 is aligned with the magnetic force midline e of thecoils shaped solenoid 31 such that bothmagnets coils vibrating plate 20 moves. In this way, the loss of the magnetic force can be effectively avoided. In other words, thesecond coil 33 must be north pole when thefirst coil 32 is south pole. Thus, when the electric current is applied to the horseshoe-shaped solenoid 31, thelower magnet 42 of thepermanent magnets 40 moves upward to approach to the magnetic force midline e according to the principle that unlike magnetic poles attract each other. When the direction of the electric current is so changed that the polarities of thecoils upper magnet 41 moves downward to approach to the magnetic force midline e. As a result, the up-and-down vibration is achieved. - In order to achieve an effective restriction of the vibration intensity, a supporting
rod 23 is disposed at the center of afixing base 22. Moreover, acushioning element 24 is attached to the top of the supportingrod 23 while the other end of thecushioning element 24 is connected to the bottom of thevibrating plate 20. - According to the above-mentioned principle, as shown in
FIGS. 4 and5 , the present invention can be applied to an exercise apparatus such aselectric treadmill 50. Theelectromagnetic sensors 30 are disposed at the bottom of a runningboard 51 while bothmagnets board 51. Moreover, the horseshoe-shaped solenoid 31 is secured to a supportingrod 54 of alateral shaft 53 of thebase frame 52. In this way, the runningboard 51 creates an up-and-down vibration without affecting the original rotation effect of a continuous movingbelt 55. In addition, acushioning element 56 is interposed between the runningboard 51 and thebase frame 52. - Many change and modifications in the above-described embodiments of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims
