Problems solved by technology

[0002] Mechanical vibration is a common phenomenon in engineering technology and daily life. In most cases, mechanical vibration is harmful. Springs have the function of buffering and damping. Therefore, springs are often used in existing shock absorbers for vibration reduction. There is no other way
And once the spring in the shock absorber is made, its stiffness characteristic line is determined, which cannot be changed, and online real-time control of vibration cannot be performed.

Embodiment 1

[0019] Embodiment 1. The magnetic shock absorber of this embodiment, its structural diagram can be obtained from image 3 and Figure 4 See in, it contains inner core 1, outer bladder 2, magnet 3, fixed plate 4 and the adjustable magnetic flux magnet device that is installed on outer bladder 2 bottom surfaces.

[0020] When in use, the inner core 1 is fixed on the object to be damped, and the outer bladder 2 is fixed on the foundation. The magnets 3 on the front, back, left, right, and bottom sides of the inner core 1 are directly fixed by screws, and the magnets 3 on the outer tank 2 are first fixed on a fixed plate 4, and the inner core 1 is put into the outer tank 2. The inner core 1 and the outer tank 2 are connected with bolts and nuts, and then the fixed plate 4 with the magnet 3 is fixed on the front, rear, left, right and bottom surfaces of the outer tank 2 by screws, and its positions correspond to the positions on the inner core 1. face magnet. After installation,...

Embodiment 2

[0025] Embodiment 2. The magnetic shock absorber of this embodiment, its structural diagram can be obtained from Figure 5 Seen in, it differs from Embodiment 1 in that: the magnet 3 on the bottom surface of the outer bladder 2 is replaced with a DC electromagnet 9, and a gravity sensor 10 is installed on the inner core 1. The vibration frequency of the object to be damped can transmit the vibration signal to the microcomputer through the gravity sensor 10, and the microcomputer immediately adjusts the magnetic flux of the DC electromagnet 9 to change the repulsive force between the DC electromagnet 9 and the magnet 3 to reduce vibration. Real-time control, relatively speaking, can reduce the vibration frequency to zero, so that the vibration reduction can achieve the best effect.

Embodiment 3

[0026] Embodiment 3. A damping unit of the present embodiment series magnet shock absorber, its structural diagram can be from Figure 6 It can be seen from the above that it is different from Embodiment 1 and Embodiment 2 in that: the outer bladder 2 of the magnet damper in Embodiment 2 is made into an I-shaped shape, and the inside is a through hole, and the upper end is put into the upper inner core 1a, The lower end is put into the lower inner core 1b, and a set of magnets is added to the four sides of the outer tank 2, that is, a total of 8 pairs of magnets are installed on the outer tank 2, the DC electromagnet 9 is installed in the middle of the outer tank 2, and the gravity sensor 10 is placed on the upper inner core 1a. , at this time a vibration damping unit that can be connected in series can be formed. It can be used alone. When in use, the upper inner core 1a of this unit is fixed on the object to be damped, and the lower inner core 1b is fixed on the foundation. ...

Abstract

This invention relates to the magnet buffer, which uses the magnet homopolarity repulsing mutually principle. The character is that it contains the inner core, the external bladder, the magnet, the fixing board, wherein a pair of the magnets are mounted at the front, back, right, left and bottom face of the inner core and the external bladder, which form 5 pairs of the magnets, they repulse mutually in hopmoplarity to produce a certain repulsion power. The magnet at the bottom of the external bladder can be changed into a regulating flux magnet device, which includes the circular magnet, the square magnet, the gear wheel, the worm; or the magnet can be changed into the direct current and mounted a gravity transformer in the inner core, which can realize the shaking real-time control by the microcomputer control. This invention dissolves the problems of the unchanged characteristic line and the unrealized real-time control.

Description

1. Technical field [0001] The invention relates to a shock absorber, in particular to a magnet shock absorber manufactured by utilizing the principle of repulsion of the same poles of magnets. 2. Background technology [0002] Mechanical vibration is a common phenomenon in engineering technology and daily life. In most cases, mechanical vibration is harmful. Springs have the function of buffering and damping. Therefore, springs are often used in existing shock absorbers for vibration reduction. There is no other methods. And once the spring in the shock absorber is made, its stiffness characteristic line is determined and cannot be changed, nor can online real-time control of vibration be performed. 3. Contents of the invention [0003] The object of the present invention is to provide a magnet shock absorber manufactured by using the principle of magnet homopolar repulsion, and its characteristic line can be adjusted. [0004] The purpose of the present invention is ach...
