Detailed Description
Fig. 1 and fig. 2 are a schematic cross-sectional structure and an exploded cross-sectional structure of the preferred embodiment of the utility model. The utility model relates to a magnetic resistance shockproof structure, a magnetic resistance shockproof structure 1 mainly comprises a first shell 10, an upper lining conductor 11, a lower lining 12, a first magnet 13, a second shell 14, a lower lining external member 15 and a second magnet 16, wherein the first shell 10 defines an opening 100 and a first accommodating space 102 communicated with the opening 100, the upper lining conductor 11 (an aluminum pipe) is arranged in the first accommodating space 102 and defines a first actuating space 110, the lower lining 12 is arranged in the first actuating space 110 and penetrates out of the opening 100, the bottom of the lower lining 12 is provided with the first magnet 13 and is positioned in the first actuating space 110, the first magnet 13 and the upper lining conductor 11 generate a slow descending state in the first actuating space 110 by utilizing Lenz's law, the second shell 14 is arranged at one side of the first shell 10 and defines a second accommodating space 140, the lower lining external member 15 is arranged in the second accommodating space 140 and defines a second actuating space 150 communicated with the first actuating space 110, the lower lining set 15 is locked to the first housing 10, and the second magnet 16 is fixed to the second actuating space 150 and maintains a fixed range of repulsion distance with the first magnet 13.
The lower lining assembly 15 is inserted and locked to the first casing 10 by a plurality of bolts 2, the distance between the lower lining assembly 15 and the first casing 10 can be adjusted by the bolts 2, the distance between the first actuating space 110 and the second actuating space 150 can be changed by adjusting, and the cushion body 3 is disposed at the distance.
In addition, the second magnet 16 is installed on the installation seat 4, the installation seat 4 can be arbitrarily fixed at the position of the second actuating space 150, and the repelling distance between the second magnet 16 and the first magnet 13 can be adjusted by arbitrarily changing the position of the installation seat 4 in the second actuating space 150.
Furthermore, the lower lining set 15 defines a stop structure 152, and the stop structure 152 can limit the moving range of the mounting seat 4 and prevent the mounting seat 4 from separating from the lower lining set 15. The stop surface 120 defined by the lower member 12 can mainly stop against the first casing 10, so as to prevent the lower member 12 from being separated from the top surface of the first casing 10.
Fig. 3 and 4 are schematic views of a cross-sectional structure of a pressing member and a cross-sectional structure of a pressing member rebounding according to the present invention. As can be seen from fig. 3, when the pressing member 12 is pressed down by gravity, the pressing member 12 can provide a buffer to resist shock, when the pressing member 12 is pressed down by the pressing force, the pressing member 12 naturally moves down along the first actuating space 110, and since the first magnet 13 is driven by lenz's law between the first magnet 13 and the upper lining conductor 11 to generate a slow-down state in the first actuating space 110, and meanwhile, a certain repulsive distance is provided between the first magnet 13 and the second magnet 16, when the first magnet 13 moves down to be close to the second magnet 16, the first magnet 13 is driven by the repulsive distance to generate a sufficient buffer force on the pressing member 12.
What is called lenz's law in the foregoing is that an induced current generated due to a change in magnetic flux has a direction that resists the change in magnetic flux. In particular, by pushing the magnet toward the copper conductor, the magnetic flux through the copper conductor is enhanced. According to lenz's law, the induced current will be counterclockwise as viewed from the magnet to the copper conductor. This is because the magnetic field generated by the induced current in the counterclockwise direction, which is opposite to the direction of the magnetic field of the magnet, makes the total magnetic field weaker than the magnetic field of the magnet, thereby resisting the change of the magnetic flux.
Conversely, if the magnet is pulled away from the copper conductor in the opposite direction, the magnetic flux through the loop is reduced. According to lenz's law, the induced current will be clockwise from the magnet to the copper conductor. This is because the magnetic field generated by the clockwise induced current, which has the same direction as the magnetic field of the magnet, makes the total magnetic field stronger than the magnetic field of the magnet, thereby resisting the change of the magnetic flux.
As described above, when the present invention is applied to an audio device, the first magnet 13 and the upper lining conductor 11 (aluminum pipe) are arranged and matched to form a state conforming to lenz's law, so that the present invention can achieve the purpose of shock resistance and buffering through the magnetic effect.
As can be seen from fig. 4, when the first magnet 13 moves to the bottom, the first magnet 13 and the second magnet 16 generate a repulsion phenomenon, and therefore, there is a repulsion distance between the first magnet 13 and the second magnet 16, when the first magnet 13 is pressed down by the pressing member 12 due to gravity, the first magnet 13 approaches the second magnet 16, and when the repulsion distance is pulled close, a rebound force is generated, so that the first magnet 13 rebounds, and the pressing member 12 is kept in the first actuation space 110, thereby achieving the shockproof effect.
As can be seen from the above, the first magnet 13 and the upper lining conductor 11 (aluminum pipe) according to the present invention are arranged and matched, and the lenz's law is applied, so as to achieve the purpose of shock resistance and buffering through the magnetic effect.
