In this embodiment, the moving element that rotates along with the rotating operation of bearing circle (not shown) is described as steering shaft 2.Yet moving element is not restricted to steering shaft 2, and can be other elements with the operation synchronous operation of bearing circle.
On the external peripheral surface of the column part 46 of locking latch 44, two circumferencial direction bevelled cam grooves 50 have been formed with respect to column part 46.The bench section of cam groove 50 is semi-round substantially, and two cam followers 32 that remain on 30 li of the longitudinal grooves of swivel 26 are engaged in 50 li of cam grooves.Thereby remain on the cam follower 32 of 26 li of swiveies and be formed on the cam groove 50 of locking on the latch 44 and constituted a cam mechanism, and the medial surface of cam groove 50 forms cam face.
In this embodiment, cam groove 50 is positioned on the locking latch 44, and cam follower 32 is positioned at 26 li of swiveies.On the contrary, cam follower 32 can be positioned on the locking latch 44, and cam groove can be positioned on the inner circumferential surface of swivel 26.
Fig. 3 shows the expansion drawing of the external peripheral surface of column part 46.Have evenly spaced perpendicular line among the figure and be and have 10 ° of step-lengths or 10 ° angle line at interval.Figure middle and upper part correspondence the front (for example, a side of steering shaft 2) of locking latch 44, and the bottom correspondence among the figure the rear end side of locking latch 44.As shown in Figure 3, one of them cam groove 50 comprises sloping portion 52 and 54, they tilt with respect to the circumferencial direction (horizontal direction among Fig. 3) of the column part 46 of locking latch 44, and extendible portion 56 and 58, extendible portion 56 and 58 extends on the circumferencial direction of column part 46 from the two ends of sloping portion 52,54.
Sloping portion 52 and 54 by one a little the part 54 of bevelled part 52 and an orientated at steep inclinations constitute, bevelled part 52 is positioned on the rear end side of locking latch 44 and a small leaning angle is arranged a little, and the part 54 of the part orientated at steep inclinations of orientated at steep inclinations is on the front of locking latch 44 and a precipitous leaning angle arranged.Just as what describe later, when cam follower 32 is positioned at 52 li of the sloping portions a little of cam groove 50, locking latch 44 is positioned at the position of contiguous locked position, and when cam follower 32 was positioned at 54 li of the very big sloping portions of cam groove 50, locking latch 44 was positioned at the position of contiguous unlocked position.That is, the angle of inclination of cam groove 50 changes according to the position of locking latch 44.
Extendible portion 56 and 58 is set makes when motor stop position A shown in the cam follower 32 arrival figure or the B driving of motor 16 stop owing to the inertia rotation fails to make immediately under the condition that motor 16 or swivel 26 stop, cam follower 32 can enter in extendible portion 56 and 58.This structure prevents stopping with the overload that preventing motor 16 suddenly and allowing the motor stop position to be set in the particular range that comprises error of motor 16. Extendible portion 56 and 58 is extending on the circumferencial direction of column part 46 also so when cam follower 32 moves into extendible portion 56 and 58, is locking latch 44 and can not move.
Another cam groove 50 has similar shape, but is formed in and be separated by 180 ° position of a described cam groove 50.When watching on the axial direction of column part 46, two cam grooves 50 have each other overlapping part on the position, but they can be not intersected with each other.
Two cam grooves 50 and two cam followers 32 of providing in the present embodiment are compared with a cam groove and a cam follower only are provided, and have when locking latch 44 activated as hereinafter described, prevent to lock the effect that latch 44 sends click sound.Yet locking latch 44 can only be activated by a cam groove 50 and a cam follower 32.In this case, cam groove 50 can form a for example long groove of spiral extension, therefore can not intersect with himself.
On the excircle of locking latch 44 rear ends, two copulational protuberances 60,180 ° the position that is provided in to be separated by.Copulational protuberance 60 slidably engages with two engaged groove 62 on being formed on shell 14 inside faces.Thereby locking latch 44 is allowed to move forward and backward but can not rotates.
Between rear end of locking latch 44 and shell 14, be provided with a spring 64 as biasing element.Spring 64 makes locking latch 44 towards steering shaft 2 biasings.
Next, the operation of the motor-driven steering lock device 10 with said structure is described.
When motor-driven steering lock device 10 was in locking state shown in Fig. 1 and 2, along with being rotated in the forward of motor 16, swivel 26 beginnings were gone up rotation at unlocking direction shown in Figure 1 (that is anticlockwise direction).Along with the beginning of rotation, the detection lever climb steps part 38 of second detector switch 42 is to change or to switch swivel 26, the second detector switches 42 and then change the ON state over to.
When swivel 26 beginnings were rotated by this way, the cam follower 32 of the motor stop position A in the neighborhood graph 3 moved, and slides or rotation 50 li of cam grooves simultaneously.Yet cam follower 32 is positioned at the terminal of longitudinal groove 30 and can not moves forward.Correspondingly, the rotation of swivel 26 is moved 44 beginnings of locking latch backward.
When cam follower 32 when the sloping portion a little 52 of cam groove 50 moves, locking latch 44 is slowly drawn back from locked position by comparison.The front end that this layout has increased locking latch 44 is extracted load when the engagement groove of steering shaft 24 li is extracted.Thereby locking latch 44 can be extracted reliably, even be applied under the inner surface that static steering torque on the steering shaft 2 makes engagement groove 4 and the situation that the forefront pressure of locking latch 44 contacts.In addition, be used to increase the reducing gear of extracting load or similarly part can be cancelled and the size of motor 16 can reduce.This can reduce the quantity of parts and reduce motor-driven steering lock device 10 as a single-piece size.
When cam follower 32 next along with the rotation of swivel 26 when the part 54 of the orientated at steep inclinations of cam groove 50 moves to motor stop position B, locking latch 44 comparatively speaking retreats fast.Thereby the operating time length of motor is reduced in the front end of locking latch 44 is locked latch 44 after 4 li of the engagement groove of steering shaft 2 are extracted accelerated movement.This layout accelerated to comprise be used for operating electrical machines drive steering lock apparatus 10 motor controller unit the total system response and reduced expenditure of energy.
The about 180 ° result of swivel 26 rotation is, the detection lever of first detector switch 40 through step part 36 with the conversion that is used for swivel 26 and fall into groove 34, so that therefore first detector switch 40 changes the OFF state over to.When first detector switch 40 received the OFF signal, being rotated in the forward of motor 16 stopped, and stopped then because the inertia rotating cam driven member 32 of electric motor 16 and swivel 26 enters the extendible portion 58 of cam groove 50 a little.At this moment, locking latch 44 has returned to unlocked position, and the front end of wherein locking latch 44 returns to herein and covers 12 li, as shown in Figure 4.
In this manner, locking latch 44 activated from locked position and arrives unlocked position, the front end of locking latch 44 and then be disengaged with the engagement groove 4 of steering shaft 2, and the limit rotation of steering shaft 2 is disengaged, the bearing circle release.
On the contrary, enter locking state for making motor-driven steering lock device 10, motor 16 antiports change OFF state shown in Figure 1 over to up to second detector switch 42.Swivel 26 and then about 180 ° of locking direction shown in Figure 1 (that is, clockwise direction) rotation, and the rotation of swivel 26 makes cam follower 32 move to motor stop position A along cam groove 50.Along with such motion of cam follower 32, the bias force that is applied by spring 64 makes locking latch 44 advance to locked position shown in Figure 2 from unlocked position.Thereby the front end of locking latch 44 enters in the engagement groove 4 and with the engagement groove 4 of steering shaft 2 and engages, and the rotation of steering shaft 2 is limited, and bearing circle is locked.
According to the motor-driven steering lock device 10 of present embodiment, as mentioned above, locking latch 44 is driven or is activated by the swivel 26 that rotates on the direction vertical with the moving direction of locking latch 44, and locking latch 44 is set at the inside of swivel 26.Therefore, the size of motor-driven steering lock device 10 can reduce.In addition, cam groove 50 can easily form, and two cam grooves 50 or long cam groove 50 formed shape can make them can be not intersected with each other or can not intersect with himself, and this is because cam groove 50 is formed on the external peripheral surface of locking latch 44.
Because two cam grooves 50 and two cam followers 32 are provided, the click sound that locking latch 44 sends when being driven or activating is than only providing the device of a cam groove 50 and a cam follower 32 little.
Suppose that two cam followers 32 are provided with the out-of-position position each other at the axial direction with respect to swivel 26, the column part 46 of the locking latch 44 that swivel 26 and cam groove 50 form thereon extends this side-play amount in the axial direction, and the size of motor-driven steering lock device 10 done very big.By comparison, on the same plane vertical, provide two cam followers 32 that the length of the column part 46 of swivel 26 and locking latch 44 is reduced, and reduce the size of motor-driven steering lock device 10 with the axial direction of swivel 26.
And, by the cam follower 32 that constitutes by the spherical ball element as the driving of the locking latch 44 of intermediary or activate the wearing and tearing that can prevent cam groove 50, the generation of abnormal sound, and similar situation, and reduce the resistance of cam follower 32 when 50 li of cam grooves are mobile.
Next, the engagement groove 4 of describing steering shaft 2 when locking latch 44 moves to locked position with reference to Fig. 5 not with the corresponding to situation of front end of locking latch 44 under, the operation of motor-driven steering lock device 10.
The front end of locking latch 44 not with the engagement groove 4 corresponding to situations of steering shaft 2 under and when carrying out locking operation, locking latch 44 can not insert the engagement groove 4 of steering shaft 2, and the blocked external peripheral surface with steering shaft 2 of its front end contacts.Yet in this case, cam follower 32 can retreat along the longitudinal groove 30 of swivel 26, and therefore the obstruction of locking latch 44 can not stop the rotation of swivel 26 and motor 16.Normally stop at reverse running motor 16 after second detector switch 42 changes the OFF state over to.
When the engagement groove 4 that makes steering shaft 2 when the ensuing rotating operation of bearing circle is consistent with the front end of locking latch 44, the bias force that is applied by spring 64 makes the front end of locking latch 44 insert the engagement groove 4 of steering shaft 2, moves to locked position so that lock latch 44.
According to aforesaid motor-driven steering lock device 10, when the Halfway Stopping of locking latch 44 in locking operation, locking latch 44 can move to locked position and can not make motor 16 overloads and need not make motor 16 retrys.
Directly engage although lock latch 44 in the present embodiment, be not limited to this with the engagement groove 4 of steering shaft 2.For example, can provide the another kind of locking element that engages with engagement groove 4, and locking element can be driven or be activated by locking latch 44.
Although fully described the present invention with reference to accompanying drawing, it is noted that various changes and revising is conspicuous to those skilled in the art.Therefore, unless departed from scope of the present invention, any such change and modification all should be counted as comprising in the present invention.
