And in shell 2, as shown in Figure 1 and Figure 4, accommodate locking component 5, this locking component 5 is made up of the roughly cylindric actuator 6 and the tabular lock(ing) bolt 7 that can be housed in up or down in this actuator 6 being carved with outer screw section 6a in lower end periphery portion.Wherein on lock(ing) bolt 7, form elongated hole 7a longer along the vertical direction, be laterally inserted through elongated hole 7a by making pin 8 and lock(ing) bolt 7 and actuator 6 are linked.Like this, just the scope of movement in elongated hole 7a can make above-below direction and link relatively movably at pin 8 between actuator 6 and lock(ing) bolt 7.
Above-mentioned lock(ing) bolt 7 can be chimeric up or down with the elongated rectangular through-hole 3a (with reference to Fig. 2) being formed at described cover 3, and be compressed spring 9 force be upward arranged between this lock(ing) bolt 7 and partition wall 6b of actuator 6 all the time.The leading section of this lock(ing) bolt 7 engages with the recess of the described axle collar (with reference to Fig. 3) selectively, and in order to reduce the pulling capacity of extracting this lock(ing) bolt 7 from the axle collar 21 (steering shaft 20), the two sides of the leading section of lock(ing) bolt 7 is made the conical surface 7b (with reference to Fig. 3) of tapered.In addition, as shown in Figure 1 and Figure 4, the part in the periphery of lock(ing) bolt 7 forms hook step portion 7c.
As shown in Figure 1 and Figure 4, the upper periphery of described actuator 6 forms the operating portion 6A bending to L-shaped, and form connecting hole 6c in the part of vertically standing up of this operating portion 6A.
Again as shown in Figure 1 and Figure 4, in shell 2, accommodate rotatable gear part 10, the lower, outer perimeter of this gear part 10 be straightened be arranged on described lid 4 inside face (upper surface) on cylindric gear holding cylinder portion 4a be held in rotatable.And in the lower, outer perimeter of this gear part 10, form gear on worm 10a, then form female threaded portion 10b in inner circumferential.
The bottom of described actuator 6 is inserted into the inside of said gear component 10, and the described outer screw section 6a being formed at the lower, outer perimeter of this actuator 6 engages with the described female threaded portion 10b of the inner circumferential being formed at gear part 10.And, compress between cylindric spring perch 4b on the central part of gear holding cylinder portion 4a being formed at the lid 4 and partition wall 6b of actuator 6 and spring 11 be installed, locking component 5 (actuator 6 and lock(ing) bolt 7) all the time by spring 11 upward (the latched position direction that lock(ing) bolt 7 engages with the recess 21a of the axle collar 21) exert a force.
In addition, in shell 2, receive not shown electro-motor with the state of laterally placing and be used as electric actuator, the output shaft 12 of this electro-motor is formed the worm screw 13 of path, and this worm screw 13 engages with the described gear on worm 10a of the periphery being formed at gear part 10.Herein, worm screw 13 and worm screw 10a form the driver train of the advance and retreat power rotational force of the output shaft 12 of electro-motor being converted to locking component 5.
On the other hand, as shown in Figure 1 and Figure 4, remain the L-shaped of (direction orthogonal with the moving direction of locking component 5) movement in left-right direction can lock hill holder 14 in the collecting of the top of shell 2, the horizontal part 14A of this locking hill holder 14 forms engagement section, its front end engages with the described hook step portion 7c of the periphery being formed at lock(ing) bolt 7 selectively, form inclined plane shape camming surface 14a at vertical component effect 14B, this inclined plane shape camming surface 14a engages with the part of periphery of described connecting hole 6c of the operating portion 6A being formed at actuator 6.And the camming surface 14a locking the hill holder 14 and operating portion 6A of actuator 6 that engages with it just forms cam mechanism.And this locking hill holder 14 is exerted a force to engagement direction (direction that horizontal part 14A engages with the hook step portion 7c of lock(ing) bolt 7) by the compression spring 15 be arranged between itself and the inner face of shell 2.
In addition, in shell 2, receiving in the rectangular box incorporating section 2A formed near described locking hill holder 14 (with reference to Fig. 2 and Fig. 5) can along the secondary locking block 16 of fore-and-aft direction (above-below direction in Fig. 2 and Fig. 5) movement orthogonal with the moving direction of locking hill holder 14, this secondary locking block 16 by compression be arranged on spring 17 between itself and the inner face of shell 2 to the side of yieldinging in the opposite direction (being the direction keeping locking hill holder 14 and the engaging of lock(ing) bolt 7, the below namely in Fig. 2 and Fig. 5) exert a force.
And as shown in Figure 1 and Figure 4, under the state that lid 4 is arranged on shell 2, the leading section erectting the retaining pin 18 be arranged on this lid 4 engages with the rectangle connecting hole 16a being formed at secondary locking block 16, and as shown in Figure 2 and Figure 5, secondary locking block 16 makes a concession the yielding position to not hindering the movement of locking hill holder 14.
Below the action (locking/unlocking action) of the electric steering-lock device 1 of said structure is described.
Under the out-of-work state of not shown engine, as shown in Figure 1, the lock(ing) bolt 7 of locking component 5 is in the latched position of the upper limit, its upper end is stretched out to shell 2 from the through hole 3a of cover 3, and as shown in Figure 3, its leading section engages with the recess 21a of the axle collar 21 be fitted and fixed with on steering shaft 20, thus locks the rotation of this steering shaft 20.Thus, rotating operation can not be carried out to not shown bearing circle under this steering locking state, vehicle can be prevented by this stolen.
In addition, under steering locking state, as depicted in figs. 1 and 2, the front end of horizontal part 14A locking hill holder 14 engages with the hook step portion 7c of lock(ing) bolt 7, lock(ing) bolt 7 is kept in the locking position, and stops this lock(ing) bolt 7 mobile to direction of unblanking (below in Fig. 1).Thus, even if in order to reduce pulling capacity that lock(ing) bolt 7 extracts from the axle collar 21 and the leading section of this lock(ing) bolt 7 be made the conical surface 7b of tapered, this lock(ing) bolt 7 also can be subject to the movement of lockset position of coupler the prevention locking hill holder 14, therefore very large power is namely used forcibly to apply rotation process to the bearing circle be in the lock state, lock(ing) bolt 7 also can not move, pressure is prevented to unblank, therefore, it is possible to play this electric steering-lock device 1 anti-theft feature originally.
But, under the steering locking state that lock(ing) bolt 7 is in latched position, as shown in Figure 1, the gap delta shown in formation figure between the elongated hole 7a be formed on lock(ing) bolt 7 and pin 8.
Once not shown engine start switch is placed in ON position by driver in the above-described state, not shown ECU sends unlocking signal to electric steering-lock device 1 after this situation being detected.So, just make it start to not shown power electric motors, thus its output shaft 12 is rotated forward.
Once electro-motor starts as described above and makes its output shaft 12 rotate forward, this rotation is just slowed down by worm screw 13 and gear on worm 10a and is delivered to gear part 10 after converting direction to right angle to make this gear part 10 and rotates, and the actuator 6 being therefore formed with the outer screw section 6a be screwed with the female threaded portion 10b be engraved in this gear part 10 inner circumferential just overcomes the force of spring 11 and moves down.Now, due to as previously mentioned, between the elongated hole 7a and pin 8 of lock(ing) bolt 7, form the gap delta shown in Fig. 1, therefore first only have actuator 6 to move down, lock(ing) bolt 7 is positioned at latched position and does not move.
When only having actuator 6 to move down as described above, the part of the periphery of the connecting hole 6c that the operating portion 6A of this actuator 6 is formed the just camming surface 14a of urge lock hill holder 14 and the force making this locking hill holder 14 overcome spring 15 moves to the right in Fig. 1 and Fig. 2, therefore as shown in Figure 4 and Figure 5, the hook step portion 7c of the horizontal part 14A disengaging locking bolt 7 of locking hill holder 14 and remove the two engaging, makes lock(ing) bolt 7 move.
Then, pin 8 is made to engage with the elongated hole 7a of lock(ing) bolt 7 as shown in Figure 4 by moving down of actuator 6, namely actuator 6 forms one and moves down with lock(ing) bolt 7, when electro-motor by driven by not shown timer set time and make lock(ing) bolt 7 arrive the lockset position of coupler of lower limit as shown in Figure 4 time, the through hole 3a inside of cover 3 is made a concession in the upper end of this lock(ing) bolt 7 namely, therefore lock(ing) bolt 7 is made to remove with the engaging of the recess 21a of the axle collar 21, and make the latch-release of steering shaft 20 and become unlocking condition, thus driver just can steering wheel rotation.But, in the present embodiment, the structure stopped immediately after the time being through by set timer that electro-motor adopts, but also can adopt following structure: the control position detection part detected the control position of lock(ing) bolt 7 or actuator 6 is set, once this control position detection part detects that lock(ing) bolt 7 has arrived the situation of lockset position of coupler, electro-motor is made to stop immediately.
And, when vehicle stops and engine start switch is placed in OFF position to be cut off by engine by driver, after ECU detects this situation, send locking signal to electric steering-lock device 1.So, to the power electric motors of electric steering-lock device 1, this electro-motor is started, and its output shaft 12 is reversed.
Once the output shaft 12 of electro-motor reverses as described above, its rotation is delivered to gear part 10 through worm screw 13 and screw gear 10a immediately, this gear part 10 reverses and actuator 6 is moved up, but lock(ing) bolt 7 is exerted a force upward by spring 9, the state that the pin 8 of the elongated hole 7a and actuator 6 that are therefore maintained at this lock(ing) bolt 7 engages, actuator 6 and lock(ing) bolt 7 are formed integrally and move up.And, first when lock(ing) bolt 7 arrives the latched position of the upper limit as shown in Figure 1, the upper end of this lock(ing) bolt 7 just engages with the recess 21a of the axle collar 21 as shown in figures 1 and 3 like that, therefore just become the lock-out state that the rotation of steering shaft 20 is locked, thus when can prevent from stopping, vehicle is stolen.And when lock(ing) bolt 7 fails to engage well with the recess 21a of the axle collar 21, lock(ing) bolt 7 just can overcome the force of spring 9 in the scope of movement in the elongated hole being formed at this lock(ing) bolt 7 at pin 8 and move down, and therefore can not apply excessive load to lock(ing) bolt 7.
Even if after lock(ing) bolt 7 moves to latched position as described above, actuator 6 also can move in the scope of movement in the elongated hole 7a of this lock(ing) bolt 7 at pin 8, therefore this actuator 6 is just moved upwards up to its upper end as shown in Figure 1 and abuts with the wall 2a of shell 2, and between the pin 8 be located on this actuator 6 and the elongated hole 7a of lock(ing) bolt 7 gap delta shown in formation figure, and once have passed through the time set by timer, electro-motor stops immediately.
In addition, because when actuator 6 moves up, its operating portion 6A also together moves up, therefore the locking hill holder 14 that camming surface 14a engages with the connecting hole 6c of this operating portion 6A can be mobile to engagement direction (left in Fig. 1 and Fig. 2) because of the force of spring 15, and the leading section of its horizontal part 14A engages with the hook step portion 7c of lock(ing) bolt 7 as illustrated in figures 1 and 2, make lock(ing) bolt 7 be locked hill holder 14 to the movement in direction of unblanking to stop, thus can reliably prevent pressure from unblanking.
But, in the present embodiment, what electro-motor adopted is once have passed through the structure that time of being set by timer just stops immediately, but also can adopt following structure: the control position detection part detected the control position of actuator 6 is set, once this control position detection part detects that actuator 6 has arrived the situation of latched position (position shown in Fig. 1), electro-motor is made to stop immediately.
But, as shown in Figure 1, when lock(ing) bolt 7 is in latched position and locking hill holder 14 is in the steering locking state engaged with the hook step portion 7c of lock(ing) bolt 7, once there be people to take off lid 4 from shell 2 as shown in Figure 6 to steal, because the retaining pin 18 be located on this lid 4 departs from the connecting hole 16a of secondary locking block 16, therefore be in the secondary locking block 16 made a concession on position just to move because of the force of spring 17, and move to as shown in Figure 7 on the holding position of prevention locking hill holder 14 movement.The state that locking hill holder 14 therefore can be kept to engage with lock(ing) bolt 7, also can stop lock(ing) bolt 7 to move to direction of unblanking even if taken off by lid 4.
Like this, even if lid 4 is taken off and pulls actuator 6, also can maintain the fastening state of locking hill holder 14 and lock(ing) bolt 7, and lock(ing) bolt 7 cannot be made to move to lockset position of coupler, therefore, it is possible to reliably antitheft.
But, when when comprise that for theft object, lid is taken off from shell time by lock(ing) bolt locking locking structure in the locking position, usual needs arrange the special hill holder of the lockable mechanism that engages with lock(ing) bolt, but in the present embodiment, locking hill holder 14 is also used as the hill holder of lockable mechanism, therefore, it is possible to minimizing number of parts, and due to multiple hill holder need not be arranged near lock(ing) bolt 7, therefore, it is possible to saving space, and then realize the miniaturization of electric steering-lock device 1.
