Brief description
Fig. 1 is a kind of switchable IAC schematic diagram of magnetic direction proposed by the present invention；
Fig. 2 is schematic diagram under another state of the switchable IAC of magnetic direction shown in Fig. 1.
Specific embodiment
With reference to Fig. 1, Fig. 2, a kind of switchable IAC of magnetic direction proposed by the present invention, including shell 1, axis body
2nd, permanent magnet 3, solenoid 4, card-bit part 5, the first cushion pad 6, locating part 7, the second cushion pad 8, first power supply the 9, second electricity
Source 10, ecu (electronic control unit, electronic control unit) module 11 and switching switch 12.
In axis body 2 first end insertion shell 1, permanent magnet 3 is arranged on inside axis body 2, and permanent magnet 3 pole orientation and axis body
2 length directions are parallel.
First cushion pad 6 be arranged on shell 1 and circumferentially distributed outside axis body 2.Locating part 7 is arranged close to axis body 2
At second end and circumferentially distributed outside axis body 2, the second cushion pad 8 is arranged on the side near the first cushion pad 6 for the locating part 7.
Axis body 2 is provided with card-bit part 5 and is located between the first cushion pad 6 and the second cushion pad 8.Axis body 2 can be along length
Move in direction, card-bit part 5 can coordinate shell 1 and locating part 7 that the move distance of axis body 2 is limited, it is to avoid axis body 2 is crossed and shipped
Move and cause accident.First cushion pad 6 contacts with the second cushion pad 8 and applies opposition to the axis body 2 in motion during card-bit part 5
And it is gradually increased thus row buffering is entered to the axis body 2 in quick moving, it is to avoid the infringement such as collision that brake hard produces.
In present embodiment, the first cushion pad 6 and the second cushion pad 8 are rubber blanket, and it is cheap, and elasticity is good, delay
Rush effect preferable.Axis body 2 second end is rounded corners structure, it is to avoid wedge angle cutting risk of collision in motor process.
Solenoid 4 is installed inside the housing and is enclosed within axis body 2 periphery.
By cable screw around forming, cable first end and the second end are respectively equipped with the first binding post 41 to solenoid 4
With the second binding post 42, the first binding post 41 passes through switching switch 12 and selectively connects the first power supply 9 or second source
10, the second binding post 42 connects the first power supply 9 and second source 10 respectively.
First power supply 9 cathode and anode directions are contrary with second source 10 cathode and anode directions, the first binding post 41 connection first
When connecting second source 10 with the first binding post 41 during power supply 9, in solenoid 4, the sense of current is contrary, thus producing direction
Contrary magnetic field simultaneously applies rightabout active force to control axis body 2 direction of motion to permanent magnet 3.

41 with the first power supply 9 or connect the first binding post 41 and second source.
When the first binding post 41 is connected with the first power supply 9, solenoid 4 produces and permanent magnet 3 direction identical magnetic
, magnetic field is relative with permanent magnet 3 opposite pole thus to permanent magnet 3 generation captivation, now, axis body 2 is along its length to the
One cushion pad 6 moves to card-bit part 5 against the first cushion pad 6.
When the first binding post 41 is connected with second source 10, solenoid 4 produces the magnetic in opposite direction with permanent magnet 3
, magnetic field is relative with permanent magnet 3 like pole thus to permanent magnet 3 generation repulsive force, axis body 2 is along its length to locating part 7
Move to card-bit part 5 against the second cushion pad.
In present embodiment, with the switching of the sense of current, the timely motion switch direction of axis body 2, take off from standing state
From solving the situation that field collapses process leads to axis body 2 motion time delay.
In present embodiment, between ecu module 11 and switching switch 12, it is connected with drive mechanism, ecu module 11 is passed through to drive
Dynamic mechanism controls switching switch 12 switching communication path, so, can avoid the limitation of motor switch, increase switching switch 12 choosing
Select scope, reduce switching switch 12 costs.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any those familiar with the art the invention discloses technical scope in, technology according to the present invention scheme and its
