Detailed description of the invention
Advantages of the present invention is expanded on further below in conjunction with accompanying drawing and specific embodiment.
Shown in accompanying drawing 1, the gear 5 of the electronic steering column locking device of the present invention, including gear mass, this gear mass includes
First end 509 and the second end 510, is wherein provided with tooth 501 around the first end 509, and the end face of the second end 510 is provided with
First curve projection 502 and the second curve projection 503.
Preferably, this tooth 501 is left-handed helical teeth, convenient engagement.In conjunction with accompanying drawing 4,5 understand, and it can be with motor 2 end
Worm screw 3 coordinate.Under the driving of motor 2, gear 5 can rotate clockwise or counterclockwise.
Preferably, the first curve projection 502 is placed in the second curve projection 503 inner ring.
Preferably, the second curve projection 503 includes first end 507 and the second end 508, the second curve projection 503
With first end 507 as starting point, extend a distance into the bending of backward gear internal, form the second end 508.
Preferably, the first curve projection 502 is with the position within close gear 5 as starting point, with spiral shape outside gear
Edge extends, thus forms the sliding tray 504 mated with the end face 1501 of guide rod 15.
Preferably, the first curve projection 502 is double-layer curve, is provided with reinforcement between double-layer curve.Preferably exist
First curve projection 502 is provided with a normal direction away from one end of gear centre and is perpendicular to the first block of the first curve projection
506.Second curve projection 503 is provided with a normal direction and is perpendicular to the second of the second curve projection near one end of gear centre
Block 505.
Gear 5, can drive the safety slide 14 in locking system and connection to have the guide rod 15 of latch 9 to move, in conjunction with attached
Fig. 2,3 understand, and safety slide 14 has two semicolumn 1403a and 1403b, and it can be dashed forward with the second curve of gear 5
Rise and 503 match, safety slide 14 further have the safety slip build 1401 matched with latch 9 and with
The microswitch touch panel 1402 that microswitch contacts.Guide rod 15 has the end face 1501 matched with sliding tray 504,
Guide rod 15 still further comprises latch groove 1502 and the Magnet hold-down support 1503 connecting latch 9.
Gear 5 and safety slide 14 and to be connected the concrete principle having the guide rod 15 of latch 9 to move as follows:
First curve projection 502 of gear 5, contacts with the end face 1501 of guide rod 15.The cylinder on latch 9 top is placed in
In the latch groove 1502 of guide rod 15.Latch 9 top end face is pressed with a spring, a downward pressure is provided all the time
Power.Guide rod 15 is under the effect of spring pressure, and the end face 1501 of guide rod 15 is pressed in the first curve projection 502 straight down
On.And the second curve projection 503 of gear 5, then two semicolumn 1403a and 1403b with safety slide 14 match
Closing, the second curve projection 503 is placed between two semicolumn 1403a and 1403b, thus safety slide 14 is along second
Path defined in curve projection 503, opposed gear 5 radial direction is moved.
In conjunction with accompanying drawing 4,5, the work process of one embodiment of the present invention is as follows:
There is a Magnet hold-down support at the top of described guide rod 15, can be used for fixed magnet 12.Magnet 12 and Hall switch
101 coordinate, the lock signal in output when electronic steering column locking device is in locking state.In the side of safety slide 14,
There is a microswitch touch panel 1402, export unlocking signal when electronic steering column locking device is in released state.
When electronic steering column locking device is in locking state, Magnet 12 can trigger Hall switch 101 and make Hall switch 101
The signal of output Guan Bi, and the output of microswitch 102 no signal.When electronic steering column locking device receives and unlocks instruction,
Gear 5 rotates counterclockwise under motor 2 drives, and guide rod 15 drives latch 9 to move up along sliding tray 504.When
Latch is to after unlocked position, and safety slide 14 is along route defined in the second curve projection 503, by first end 507
Mobile to the second end 508, i.e. it is moved to the left.Thus safety slide 14 is near latch 9, latch 9 is stoped to lock
Steering column 6(is i.e. in the second state).Meanwhile, microswitch touch panel 1402 contacts with microswitch 101, now fine motion
Switch 1402 output closure signal, Hall switch 101 exports opening signal, and motor 2 stops operating, and completes electrical steering
The releasing process of post locking device.And preferably, latch 9 is provided with safety slide groove 901, it is used for accommodating safety slide
1401.
Otherwise, when electronic steering column lock receives and locks instruction, gear rotates clockwise under motor 2 drives, safety slip
Block 14, along route defined in the second curve projection 503, is moved to first end 507 by the second end 508, i.e. to
Move right.Thus safety slip build 1401 removes safety slide groove 901, safety slide 14, away from latch 9, does not stops
Latch 9 locks steering column 6(and is i.e. in the first state).Latch 9 move down under the effect of spring pressure (by
Being the curvilinear structures that a radian is less in the first curve projection 502, sliding tray 504 only drives guide rod and latch 9 upwards
Motion, rather than direct it towards lower motion).When guide rod 15 arrives upper lock position, Hall switch 101 closes, and fine motion is opened
Closing 102 to open, motor 2 stops operating, and completes the process of locking of electronic steering column locking device.
It should be noted that, the most herein " on " D score " left " " right " only represents the contra in accompanying drawing
To, not actual installation direction.
It should be noted that, embodiments of the invention have preferably implementation, and not the present invention is made any type of limit
System, any one skilled in the art changes possibly also with the technology contents of the disclosure above or is modified to the effective of equivalent
Embodiment, as long as without departing from the content of technical solution of the present invention, being made above example according to the technical spirit of the present invention
Any amendment or equivalent variations and modification, all still fall within the range of technical solution of the present invention.
