Latched position ferromagnetic material 82 and unlocked position ferromagnetic material 83 are configured to independently component respectively, are all formed by iron plate in present embodiment.
Fig. 4 illustrates the state of observing substrate 70 from the right side of Fig. 2, the relation of substrate 70, latched position ferromagnetic material 82 and unlocked position ferromagnetic material 83.
When observing from magnet 33 side, latched position ferromagnetic material 82 is configured to overlap with Hall element 72, and unlocked position ferromagnetic material 83 is configured to overlap with Hall element 73.
Latched position ferromagnetic material 82 and unlocked position ferromagnetic material 83 have the effect guided from the magnetic line of force of magnet 33.Namely, when not arranging latched position ferromagnetic material 82 and unlocked position ferromagnetic material 83, the magnetic line of force that magnet 33 produces spreads to various direction, so when magnet 33 is positioned at latched position or unlocked position, the magnetic flux density arriving the magnetic line of force of Hall element 72 or Hall element 73 is low.To this, in the present embodiment, because latched position ferromagnetic material 82 and unlocked position ferromagnetic material 83 guide the magnetic line of force from magnet 33, so when magnet 33 is positioned at latched position or unlocked position, the magnetic flux density arriving the magnetic line of force of Hall element 72 or Hall element 73 uprises.
In the past, in order to improve the magnetic flux density of the magnetic line of force arriving Hall element 72 or Hall element 73, although magnet 33 uses the neodium magnet that the expensive magnetic force produced is strong.To this, owing to being provided with latched position ferromagnetic material 82 and unlocked position ferromagnetic material 83 in present embodiment, even if so the magnetic force of magnet 33 generation is little, the magnetic flux density arriving the magnetic line of force of Hall element 72 or Hall element 73 also can uprise.Therefore, although the magnet 33 of present embodiment can adopt the ferrite lattice of the weak cheapness of the magnetic force produced than neodium magnet.In addition, although magnet 33 employs more cheap magnet in present embodiment, such as, also can adopt expensive neodium magnet, thus the more reliable than ever and position probing that precision is high can be carried out.
In addition, the area of preferred latched position ferromagnetic material 82 and the opposed faces relative with the magnet 33 shown in Fig. 4 of unlocked position ferromagnetic material 83, below the area of the opposed faces relative with unlocked position ferromagnetic material 83 with latched position ferromagnetic material 82 of magnet 33.This is because, if the area of latched position ferromagnetic material 82 and unlocked position ferromagnetic material 83 becomes large, magnetic line of force then from magnet 33 spreads, if instead the area of latched position ferromagnetic material 82 and unlocked position ferromagnetic material 83 diminishes, then the magnetic line of force from magnet 33 is concentrated.
And the shape of the shape of the opposed faces of preferred latched position ferromagnetic material 82 and unlocked position ferromagnetic material 83 and the opposed faces of magnet 33 is similar shape.Thus, the magnetic line of force that magnet 33 produces can not get muddled and easily concentrate towards latched position ferromagnetic material 82 and unlocked position ferromagnetic material 83.
In present embodiment, the shape and size of the opposed faces of latched position ferromagnetic material 82 and unlocked position ferromagnetic material 83, all become the oblong consistent with the shape and size of the opposed faces of magnet 33, and therefore, their area is also all equal.
The following structure that the control system of the electric steering-lock device 1 comprising above-mentioned operating position testing agency is described according to Fig. 5.
Fig. 5 is the Control system architecture figure of electric steering-lock device 1 of the present invention.
Hall element 72,73 is electrically connected with the CPU91 as control setup of drive control motor 61.CPU91, via the communication line 93 of communication interface (communication I/F) 92 and vehicle, is electrically connected with the not shown vehicle side control part of vehicle loading.In addition, as shown in Figure 1, substrate 70 is provided with the adaptor union 80 of the function realizing communication interface 92.The not shown electric connection line extended from CPU91 is connected to described adaptor union 80.
During the detection range be centrally located near latched position of the magnet 33 arranged when lock cell 30 (arm 32d) is upper, the Magnetic Sensor detected as latched position and the Hall element 72 be arranged near latched position detects the magnetic force of magnet 33 and sent to CPU91 by detection signal.CPU91 utilizes described detection signal, judges that locking bolt 31 moves to latched position.In addition, when the detection range be centrally located near unlocked position of the magnet 33 of the upper setting of lock cell 30 (arm 32d), the Hall element 73 be arranged near unlocked position detects the magnetic force of magnet 33 and is sent to CPU91 by detection signal.CPU91 utilizes described detection signal, judges that locking bolt 31 moves to unlocked position.
Electrical motor (M) 61 is electrically connected on by locking relay 95 and unblock relay 96 battery 94 that vehicle loads.Utilize the locking signal and unlocking signal that send from CPU91 and drive locking relay 95 respectively and unlock relay 96.At this, as shown in Figure 1, projecting on adaptor union 80 have upper and lower two feeding electric motors terminals 71.These feeding electric motors terminals 71 are connected with electrical motor 61.
The action (locking or unlocking motion) of the electric steering-lock device 1 of said structure is then described.
As shown in Figure 2, under the state of not shown engine stop, the locking bolt 31 of lock cell 30 is positioned at latched position, and the upper end of locking bolt 31 is outstanding and engage with not shown steering shaft to recess 10a from the locking bolt through hole 10d of housing 10.In this condition, the rotation of steering shaft is locked, and can not carry out rotary manipulation, thus prevent vehicle stolen under described lock-out state to not shown wheel flutter.Now, the magnet 33 being contained in arm 32d is positioned near the Hall element 72 of setting on substrate 70, and CPU91 utilizes the detection signal sent from Hall element 72, identifies locking bolt 31 and is positioned at latched position.
When driver operates not shown engine start switch from above-mentioned state ON, not shown vehicle side control part detects this operation and sends unlocking request signal to electric steering-lock device 1.Thus, the CPU91 of electric steering-lock device 1 exports unlocking signal to unblock relay 96.Therefore, the unblock relay 96 shown in Fig. 5 is switched to the position shown in dotted line, and locking relay 95 is in solid line position, so flow through route in Fig. 5 shown in solid line and actuating motor 61 from the electric current of battery 94.
During actuating motor 61 described above, the rotation of the output shaft 61a of electrical motor 61 utilizes worm screw 62 and worm gear 40a and to slow down and direction is delivered to gear part 40 after being changed by right angle.Because gear part 40 rotates, so actuator 32 overcomes the application force of spring 51 and moves downwards, the outer screw section 32a that described actuator 32 is formed is threaded with the female threaded portion 40b that the inner circumferential of gear part 40 is arranged.When actuator 32 like this moves downwards, the arm 32d that utilization and actuator 32 are integrally formed and pin 34, make the locking bolt 31 be connected with actuator 32 move downwards.
When the arm 32d of actuator 32 like this moves downwards and makes locking bolt 31 arrive unlocked position as shown in Figure 3, the upper end of locking bolt 31 is kept out of the way to the inside of the locking bolt through hole 10d of housing 10.Therefore, locking bolt 31 is removed with the engaging of steering shaft, and the locking of steering shaft is become released state by removing, and driver can carry out rotary manipulation to wheel flutter.Now, when the center of the magnet 33 that the arm 32d of actuator 32 is arranged arrives the detection range near unlocked position, the aforementioned Hall element 73 be arranged near unlocked position detects the magnetic force of magnet 33 and is sent to CPU91 by detection signal.Therefore, CPU91 is identified as locking bolt 31 and moves to unlocked position, stops driving motor 61, and sends unblock end signal by communication I/F92 and communication line 93 to vehicle side control part.Its result, maintains the released state shown in Fig. 3, thus vehicle can be walked.
Then, vehicle stops, and when driver carries out rupturing operation to engine start switch and cuts off driving engine, vehicle side control part detects this operation and sends locking request signal to electric steering-lock device 1.Thus, the CPU91 of electric steering-lock device 1 exports locking signal, locking relay 95 shown in Fig. 5 is switched to dotted line position, and unlock relay 96 and be positioned at solid line position, so flow through route shown in dotted lines in Figure 5 from the electric current of battery 94, and by making electrical motor 61 reversion start, the output shaft 61a of electrical motor 61 is reversed.
When the output shaft 61a of electrical motor 61 like this reverses, its rotation is transmitted to gear part 40 via worm screw 62 and worm gear 40a.Because gear part 40 reverses, so actuator 32 is moved upward, utilizes the arm 32d and pin 34 that are integrally formed with actuator 32, the locking bolt 31 be connected with actuator 32 is moved upward.
