Printed board 64 is positioned in the screw thread of housing 11 and inserts in the logical portion 12, and the state of inserting between the projection 21 of leading to portion 12 and cover 20 with the screw thread that is clamped in housing 11 is configured.On this housing 11 adaptor union 65 is installed, this adaptor union 65 is used for respect to the two-way transmission received signal of the master controller of vehicle, and is used to receive the electric power of driving motor 26.And, the electronic unit 66 of regulation is installed on printed board 64, this electronic unit 66 comprises a pair of Hall element 59A, 59B and separates lock detection switch 63.And this printed board 64 and electrical motor 26 are electrically connected by terminal base 29.In addition, the signal that receives from master controller is the drive signal of instigating electrical motor 26 forward or reverse.And the signal that sends to master controller is meant that the rotary position information of the swivel 30 that is produced by Hall element 59A, 59B reaches the information signal of the information that detected by the release of the locking component 49 of separating lock detection switch 63 generations.Described processing is undertaken by the microcomputer as control mechanism that is installed on printed board 64.
The blocking device 10 of described structure is configured on the wall with through hole 3 with the barrel-contoured Steering gear 2 in four limits.At this moment, shown in Fig. 6 (A), make the installation portion outstanding 13 insert logical through hole 3 from the bottom surface of housing 11.Thus, the bottom surface with housing 11 of rectangular shape disposes along the wall extension of Steering gear 2.Under this state, S. A. 31 edges of swivel 30 and the roughly direction extension of quadrature of the plane of the axis that comprises steering shaft 1.In other words, the moving direction of slide block 44 is positioned at the direction of extending with the axis almost parallel of steering shaft 1.
And, because the blocking device 10 of present embodiment forms locking component 49 and swivel 30 are configured in structure on the roughly same plane of radial outside of swivel 30, therefore can realize the single-piece slimming.And, be used on slide block 44 support 47,47 of locking component 49 bindings owing to be provided with for rotating, therefore can carry out the binding of slide block 44 and locking component 49 with simple structure, and can realize the slimming of slide block 44, therefore can further realize the single-piece slimming.And then, owing to carry out the application of force, therefore can avoid maximizing by the configuration of force application component by the biserial coil spring 54 that disposes in the mode that locking component 49 is wound in S. A. 50.And, will be used to detect the S. A. 50 one configuration of rotor 60 and locking component 49 of the control position of locking component 49, can install in the space-efficient mode, therefore can further avoid maximizing.
Next, specify the work of blocking device 10.
Under the released state shown in Fig. 6 (A), if chaufeur carries out shut-down operation by key etc. to driving engine, then according to the drive signal of master controller, microcomputer is just changeing electrical motor 26, carries out locking work.So, as shown in Figure 7, swivel 30 via worm gear 28 along left-hand revolution.
Unlocked position before the locking work of this swivel 30, the first Hall element 59A that constitutes position of rotation testing agency is an off-state, the second Hall element 59B is an on-state.Then, when swivel 30 rotated to the release detection position, the second Hall element 59B can become off-state by surveyed area owing to magnet 57 leaves.And the first Hall element 59A keeps off-state.When swivel 30 continued to rotate to the lock-in detection position, the first Hall element 59A was owing to magnet 57 arrives and can become on-state by surveyed area.And the second Hall element 59B keeps off-state.The microcomputer that receives the connection signal that is produced by this Hall element 59A stops electrical motor 26.So, swivel 30 along left-hand revolution, arrived latched position before the inertia rotation of electrical motor 26 stops.Under this state, the first Hall element 59A keeps on-state, and the second Hall element 59B keeps off-state.
So, when swivel 30 during along the rotation of locking operative orientations, the follower 46 of slide block 44 arrives non-working surface 40b through camming surface 40a behind the non-working surface 40c of moving contact in the cam part 40.When the non-working surface 40c moving contact of follower 46 and cam part 40, because non-working surface 40c has identical circular-arc of distance (radius) to S. A. 31, so slide block 44 can be along the moving direction displacement.And, if follower 46 arrives camming surface 40a, then the mobile blocking portion 43 of swivel 30 moves outside rotation track on the rotation track of latched position rotation from prevention locking component 49 owing to the rotation of swivel 30, thereby locking component 49 can rotate to latched position.And because camming surface 40a has to the distance of S. A. 31 and slowly change the flow curve shape of (diminishing), so follower 46 is via locking component 49 and slide block 44, under the application force of biserial coil spring 54 to locking component 49 side shiftings.Thus, keep the moving contact state of follower 46 and camming surface 40a.And slide block 44 advances to locking component 49 sides with follower 46.And then locking component 49 is that middle mind-set latched position is rotated with S. A. 50.Afterwards, when arriving non-working surface 40b,, therefore do not produce along the displacement of the moving direction of slide block 44 because non-working surface 40b has identical circular-arc of distance to S. A. 31.
And, when locking component 49 so when latched position is rotated, the engaging protuberance 52 of front end is roughly along axial perforation (entering) the locking component inserting hole 14 of the S. A. 31 of swivel.Consequently, shown in Fig. 6 (B), engaging protuberance 52 engages with the engaging recessed part 5 of the axle collar 4 of cooresponding steering shaft 1, becomes lock-out state.In addition, in this locking during work, when engaging protuberance 52 and engaging recessed part 5 make progress in the footpath of steering shaft 1 when inconsistent, shown in Fig. 6 (C), engaging recessed part 5 becomes the state with the peripheral part butt of the axle collar 4.Consequently, even swivel 30 rotates to latched position, locking component 49 also can't move to latched position.Therefore, under this state, chaufeur can be rotated operation to turning to.And, when its rotary manipulation, if the axle collar 4 is rotated via steering shaft 1, and engaging protuberance 52 is consistent with engaging recessed part 5, and then under the application force of biserial coil spring 54, locking component 49 turns to latched position, shown in Fig. 6 (B), engaging protuberance 52 engages with engaging recessed part 5.
In addition, when locking component 49 rotates, constitute rotor 60 interlocks of lock-out state testing agency and rotate.Consequently, remove by pushing that operating portion 62 produces, separating lock detection switch 63 becomes off-state from on-state.In addition, the follower 46 of slide block 44 arrives camming surface 40a from the non-working surface 40c of cam part 40, and by behind the unlocked position P2 as its border, separates lock detection switch 63 and switches to off-state from on-state.
On the other hand, under the lock-out state shown in Fig. 6 (B), when chaufeur carried out start-up function by key etc. to driving engine, because the drive signal of master controller, microcomputer made electrical motor 26 counter-rotatings, carries out release work.So, as shown in Figure 7, make swivel 30 along clickwise via worm gear 28.
Latched position before the release work of this swivel 30, the first Hall element 59A is an on-state, the second Hall element 59B is an off-state.Then, when swivel 30 rotated to the lock-in detection position, the first Hall element 59A can become off-state by surveyed area owing to magnet 57 leaves.And the second Hall element 59B keeps off-state.When swivel 30 continued to rotate to the release detection position, the second Hall element 59B was owing to magnet 57 arrives and can become on-state by surveyed area.And the first Hall element 59A keeps off-state.The microcomputer that receives the connection signal that is produced by this Hall element 59B stops electrical motor 26.So, swivel along clickwise, arrived unlocked position before the inertia rotation of electrical motor 26 stops.Under this state, the first Hall element 59A keeps off-state, and the second Hall element 59B keeps on-state.
So, when swivel 30 when the release operative orientation rotates, the follower 46 of slide block 44 with cam part 40 in non-working surface 40b moving contact after, arrive non-working surface 40c through camming surface 40a.When the non-working surface 40b moving contact of follower 46 and cam part 40, because non-working surface 40b has the circular-arc of same radius, so slide block 44 can be along the moving direction displacement.Then, when follower 46 arrives camming surface 40a, become the flow curve of long radius shape owing to camming surface 40a slowly changes, thus follower 46 be pressed and with respect to cam member 39 radially foreign side move.Thus, slide block 44 moves along the direction of leaving locking component 49 with follower 46 interlocks.Consequently, the top is pulled locking component 49 by moving of slide block 44.And, be the center with S. A. 50, overcome the application force of biserial coil spring 54 and rotate to unlocked position.After this, when follower 46 arrives non-working surface 40c, the mobile blocking portion 43 of swivel 30 moves to the rotation track that stops locking component 49 to the latched position rotation position outside the rotation track of locking component 49 owing to the rotation of swivel 30, becomes the state that stops locking component 49 to rotate to latched position.And because non-working surface 40c has the circular-arc of identical radius, so follower 46 stops along the displacement of the moving direction of slide block 44.Consequently, moving of slide block 44 and locking component 49 also stops.
So, when locking component 49 when unlocked position rotates, the engaging protuberance 52 of front end is roughly along the moving axially of the S. A. 31 of swivel, and in the locking component inserting hole 14 that submerges.Consequently, shown in Fig. 6 (A), engaging protuberance 52 leaves (engaging is removed) fully from the engaging recessed part 5 of steering shaft 1, becomes released state.
In addition, when locking component 49 rotates, rotor 60 interlocks and rotating.Consequently, when locking component 49 becomes released state, separate lock detection switch 63 and be operated portion 62 and push, become on-state from off-state.In addition, separate lock detection switch 63 at the second Hall element 59B before off-state switches to on-state, promptly the energising of electrical motor 26, switch to on-state from off-state.This is because after locking component 49 moves to unlocked position from latched position, further makes electrical motor 26 work, and makes mobile blocking portion 43 rotations of swivel 30 move to cause on the rotation track of locking component 49.
At this, the locking component 49 of present embodiment by biserial coil spring 54 to the latched position application of force.And, overcome this application force and the keystone configuration that remains on unlocked position is realized with the engaging of cam part 40 of swivel 30 by the follower 46 of slide block 44.Therefore, under this released state, when coming off, restriction is disengaged, so locking component 49 can rotate to latched position under application force when the follower 46 of slide block 44 is damaged.Yet in the present embodiment, shown in Fig. 6 (A), in this released state, in the abutting part 53 of locking component 49, the mobile blocking portion 43 that is arranged on swivel 30 is positioned at the top on the rotation track that latched position is rotated.Therefore, even just in case owing to the unlock restriction of member 49 of the breakage of follower 46, the abutting part 53 of locking component 49 also can engage (butt) with the mobile blocking portion 43 of swivel 30, thereby stop locking component 49 to rotate to latched position from unlocked position, therefore be under the vehicle state that can travel at released state, can prevent that locking component 49 from moving to latched position.
So, blocking device 10 of the present invention constitutes and makes locking component 49 outstanding along the bearing of trend of the S. A. 31 of swivel 30, and therefore the structure that engages with steering shaft 1 can will have tabular swivel 30 along steering shaft 1 configuration.Therefore consequently, because the configuration electric steering-lock device, do not need the large space that radially extends at the peripheral part of steering shaft 1.Thus, the knee of chaufeur not with the configuration blocking device 10 interferences.
In addition, under the state of unlocked position work, can prevent that by the mobile blocking portion 43 that is arranged on swivel 30 locking component 49 from unexpectedly moving to the situation of latched position.And therefore this release mode of operation can improve safety owing to mainly be used in the situation of running vehicle.And therefore mobile blocking portion 43 need not to be provided with in addition special-purpose member owing to be arranged on the swivel 30 that is used to make locking component 49 work, can prevent that cost from uprising.
And then, owing to constitute swivel 30, therefore can improve the durability of cam member 39, and realize lightweight simultaneously by resinous gear part 33 and metal cam member 39.And, because by making cam member 39 and gear part 33 overlapping and make engagement section 36 and engage the portion's of bearing 42 engagings, gear part 33 and cam member 39 bindings for relatively moving, so can be improved assembly manipulation.
In addition, electric steering-lock device of the present invention is not limited to the structure of described embodiment, and can carry out various changes.
For example, in said embodiment, for gear part 33 and cam member 39 are assembled into and can't relatively rotate, and embeded slot 35 is set and engagement section 36 is set at gear part 33, on the other hand, fitting projection 41 is set and engaging is set at cam member 39 and bear portion 42, but also described formation member can be formed on the contrary.And then, also can constitute embeded slot 35 and fitting projection 41 only are set, reach the structure that either party in the portion 42 is born in engagement section 36 and engaging.And, though bearing portion 42, engaging constitutes by the hole that connects, also can constitute the recess that the end by direction of insertion is closed and constitute.And then, when constituting engaging and bear portion 42, also can constitute the front end that makes engagement section 36 and connect with convex by the hole that connects, by fastening generation distortion, can't break away from thereby be fixed as.
In addition, swivel 30 is not limited to the structure that one links gear part 33 and cam member 39, also can only constitute the swivel 30 that utilizes electrical motor 26 rotations to drive by gear part 33.In this case, by making cam member 39 rotations that are provided with separately with gear grooved 34 engagements.
In addition, in said embodiment, though form the mobile structure that stops of the locking components 49 that move to latched position owing to rotate by 43 pairs of mobile blocking portions, also can form the mobile structure that stops of the locking component that subtend latched position rectilinearity moves.
