In addition, in shell 2, taking in not shown electro-motor with the state of horizontal placement and be used as electric actuator, form the worm screw 13 of path on the output shaft 12 of this electro-motor, this worm screw 13 meshes with the described gear on worm 10a of the periphery that is formed at gear part 10.Herein, worm screw 13 and worm screw 10a formation converts the rotational force of the output shaft 12 of electro-motor to the driver train of the advance and retreat power of locking component 5.
On the other hand, as shown in Figure 1 and Figure 4, accommodate on the top of shell 2 that keeping can be along the mobile L font locking hill holder 14 of left and right directions (with the direction of the moving direction quadrature of locking component 5), the horizontal part 14A of this locking hill holder 14 constitutes the engagement section, its front end engages stage portion 7c engaging selectively with the periphery that is formed at lock(ing) bolt 7 described, form inclined plane shape camming surface 14a at vertical component effect 14B, this inclined plane shape camming surface 14a engages with the part of the periphery of the described connecting hole 6c of the operating portion 6A that is formed at actuator 6.And the operating portion 6A of the camming surface 14a of locking hill holder 14 and the actuator 6 that engages with it just constitutes cam mechanism.And this locking hill holder 14 be compressed be installed in its with the inner face of shell 2 between spring 15 to engaging the direction direction that engages stage portion 7c engaging of lock(ing) bolt 7 (the horizontal part 14A with) application of force.
In addition, in shell 2, in the rectangular box shape incorporating section 2A (with reference to Fig. 2 and Fig. 5) that forms near described locking hill holder 14, taking in can along with the mobile secondary locking piece 16 of fore-and-aft direction (above-below direction among Fig. 2 and Fig. 5) of the moving direction quadrature of locking hill holder 14, this secondary locking piece 16 be compressed be installed in its with the inner face of shell 2 between spring 17 to yielding side's (being the direction that engages that keeps locking hill holder 14 and lock(ing) bolt 7, i.e. below among Fig. 2 and Fig. 5) application of force in the opposite direction.
And as shown in Figure 1 and Figure 4, be installed under the state of shell 2 at lid 4, the leading section that setting is arranged on the maintenance pin 18 on this lid 4 engages with the rectangle connecting hole 16a that is formed at secondary locking piece 16, and as Fig. 2 and shown in Figure 5, secondary locking piece 16 is made a concession the yielding position that does not hinder locking hill holder 14 to move.
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, stretch out outside shell 2 from covering 3 through hole 3a its upper end, and as shown in Figure 3, its leading section engages with the chimeric recess 21a that is fixed on the axle collar 21 on the steering shaft 20, thereby locks the rotation of this steering shaft 20.Thereby, under this steering locking state, can not carry out rotating operation to not shown bearing circle, can prevent that by this vehicle is stolen.
In addition, under the steering locking state, as depicted in figs. 1 and 2, the front end of the horizontal part 14A of locking hill holder 14 engages with the stage portion 7c that engages of lock(ing) bolt 7, lock(ing) bolt 7 is remained on the latched position, and stop this lock(ing) bolt 7 to move to the direction of unblanking (below among Fig. 1).Thereby, even in order to reduce the pulling capacity that lock(ing) bolt 7 extracts from the axle collar 21 and the leading section of this lock(ing) bolt 7 is made the conical surface 7b of tapered, this lock(ing) bolt 7 is to the prevention that also can be subjected to locking hill holder 14 of moving of lockset position of coupler, therefore promptly use very big power forcibly the bearing circle that is in the lock state to be applied rotary manipulation, lock(ing) bolt 7 can not move yet, stoped and forced to unblank, therefore can bring into play this electric steering-lock device 1 anti-theft feature originally.
But, be at lock(ing) bolt 7 under the steering locking state of latched position, as shown in Figure 1, be formed at the gap delta shown in the formation figure between slotted hole 7a on the lock(ing) bolt 7 and the pin 8.
In case the driver places the ON position with not shown engine fire switch under above-mentioned state, not shown ECU sends unlocking signal to electric steering-lock device 1 after detecting this situation.So, just not shown power electric motors is made its starting, thereby its output shaft 12 is just being changeed.
In case electro-motor starts as described above and its output shaft 12 is just being changeed, this rotation is just slowed down by worm screw 13 and gear on worm 10a and direction converted to is delivered to gear part 10 behind the right angle and makes this gear part 10 rotations, therefore is formed with just to overcome the application of force of spring 11 with the actuator 6 that is engraved in the outer screw section 6a that the 10b of the negative thread portion screw thread of this gear part on 10 interior weeks combine and move down.At this moment, because as previously mentioned, form gap delta shown in Figure 1 between the slotted hole 7a of lock(ing) bolt 7 and pin 8, therefore at first have only actuator 6 to move down, 7 of lock(ing) bolts are positioned at latched position and mobile.
When having only actuator 6 to move down as described above, the part of the periphery of the connecting hole 6c that forms on the operating portion 6A of this actuator 6 is the camming surface 14a of urge lock hill holder 14 and right-hand move of the application of force in Fig. 1 and Fig. 2 that make this locking hill holder 14 overcome spring 15 just, therefore as shown in Figure 4 and Figure 5, the horizontal part 14A of locking hill holder 14 go out of lock bolt 7 engaging stage portion 7c and remove the two engaging, lock(ing) bolt 7 can be moved.
Then, by moving down of actuator 6 pin 8 is engaged with the slotted hole 7a of lock(ing) bolt 7, actuator 6 promptly forms one with lock(ing) bolt 7 and moves down, when electro-motor has been driven the time of being set by not shown timer and when making lock(ing) bolt 7 arrive the lockset position of coupler of lower limit as shown in Figure 4, the through hole 3a inside of cover 3 is promptly made a concession in the upper end of this lock(ing) bolt 7, therefore make lock(ing) bolt 7 and the axle collar 21 recess 21a engage releasing, and make the latch-release of steering shaft 20 and become unlocking condition, thereby the driver just can steering wheel rotation.But, in the present embodiment, what electro-motor adopted is the structure that stops immediately after the time of process by the timer setting, but also can adopt following structure: the control position detection part that the control position to lock(ing) bolt 7 or actuator 6 detects is set, in case this control position detection part detects the situation that lock(ing) bolt 7 has arrived lockset position of coupler, and electro-motor is stopped.
And when vehicle stops and the driver places the OFF position so that engine is cut off the engine fire switch, ECU sends locking signal to electric steering-lock device 1 after detecting this situation.So, the power electric motors of electric steering-lock device 1 is made this electro-motor starting, and make its output shaft 12 counter-rotatings.
In case 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 by spring 9 application of force upward, therefore be maintained at the state that the slotted hole 7a of this lock(ing) bolt 7 engage with the pin 8 of actuator 6, actuator 6 and lock(ing) bolt 7 formation one and move up.And, at 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 blocked lock-out state of rotation of steering shaft 20, thereby vehicle is stolen can prevent to stop the time.And when lock(ing) bolt 7 fails to engage well with the recess 21a of the axle collar 21, lock(ing) bolt 7 just overcomes the application of force of spring 9 and moves down in the scope that pin 8 can move in the slotted hole that is formed at this lock(ing) bolt 7, therefore can not apply excessive load to lock(ing) bolt 7.
Even after lock(ing) bolt 7 moves to latched position as described above, move in the scope that actuator 6 also can move in pin 8 can the slotted hole 7a at this lock(ing) bolt 7, therefore this actuator 6 just is moved upwards up to the wall 2a butt of its upper end and shell 2 as shown in Figure 1, and the gap delta shown in the formation figure between the slotted hole 7a that is located at pin 8 on this actuator 6 and lock(ing) bolt 7, and in case passed through the time of being set by timer, electro-motor stops immediately.
In addition, because its operating portion 6A also together moved up when actuator 6 moved up, so the locking hill holder 14 that camming surface 14a engages with the connecting hole 6c of this operating portion 6A can move to engaging direction (left among Fig. 1 and Fig. 2) because of the application of force of spring 15, and the leading section of its horizontal part 14A engages with the stage portion 7c that engages of lock(ing) bolt 7 as depicted in figs. 1 and 2 like that, lock(ing) bolt 7 is stoped to the mobile locked hill holder 14 of the direction of unblanking, thereby can prevent from reliably to force to unblank.
But, in the present embodiment, in case electro-motor adopts is to 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 that the control position to actuator 6 detects is set, in case this control position detection part detects the situation that actuator 6 has arrived latched position (position shown in Figure 1), electro-motor is stopped.
But, as shown in Figure 1, when lock(ing) bolt 7 be in latched position and locking hill holder 14 be in lock(ing) bolt 7 engage the steering locking state of stage portion 7c engaging the time, cover 4 in case there is the people to take off from shell 2 as shown in Figure 6 for theft, because the maintenance pin 18 that is located on this lid 4 breaks away from the connecting hole 16a of secondary locking piece 16, therefore be in and make a concession locational secondary locking piece 16 and just can move, and move to as shown in Figure 7 to stop and lock on the holding position that hill holder 14 moves because of the application of force of spring 17.Therefore can keep locking the state that hill holder 14 engages with lock(ing) bolt 7, take off and also can stop lock(ing) bolt 7 to move to the direction of unblanking even will cover 4.
Like this, take off and spur actuator 6, also can keep the fastening state of locking hill holder 14 and lock(ing) bolt 7, and lock(ing) bolt 7 is moved to lockset position of coupler even will cover 4, therefore can be antitheft reliably.
But, when comprising that the sort of will the lid when shell takes off for the theft purpose is locked in lock(ing) bolt under the situation of the locking structure on the latched position, usually need to be provided with the hill holder of the lockable mechanism special use 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 can reduce number of parts, and because a plurality of hill holders need not be set near lock(ing) bolt 7, therefore can save the space, and then realize the miniaturization of electric steering-lock device 1.
