Description
Technical field
The present invention relates to a kind of steering column for vehicle lock.
Background technology
In traditional steering column for vehicle lock, all be to insert lock core, and rotary locking cylinder carry out release and the operation of locking with key; In recent years, along with people pursue the hommization of exempting from key release and last latching operation, there are many vehicles to adopt the one-touch key starting system of exempting from both at home and abroad, the present invention program exempts from an important component part of key starting system, can realize exempting from the hommization pursuit of key release and last latching operation.
Summary of the invention
The object of the present invention is to provide a kind of steering column for vehicle lock, reasonable in design, the compact conformation of the present invention can realize exempting from key release and last latching operation, and is safe and reliable.
The invention is characterized in: a kind of steering column for vehicle lock, comprise housing and the power unit that is arranged on enclosure interior, the pcb board control module, performance element, the insurance unit, it is characterized in that: the control end of described pcb board control module is connected with power unit, with the running of control power unit, the output shaft of described power unit slows down and the power transmission of coaxial screw thread pair through the worm and wormwheel of performance element, the locking bolt that drives performance element carries out linear stretching out and retraction movement, described performance element side is provided with and is used to block locking bolt, prevents the insurance unit that locking bolt stretches out when unexpected situation.
The invention has the beneficial effects as follows: when locking bolt withdrawal housing, the insurance card arm of insurance unit blocks locking bolt, prevents that locking bolt from stretching out when unexpected situation, and this moment, the steering column for vehicle lock was released state, and the steering wheel rotating shaft can be rotated; Otherwise when locking bolt stretched out housing, the steering column for vehicle lock was locking state, and the steering wheel rotating shaft cannot be rotated.In the release of steering column for vehicle lock with when locking two states, permanent magnet is just in time in alignment with two place's inductive switches of pcb board control module on the locating piece; Excessive when locking bolt motion, or inductive switch was when losing efficacy, and screw thread pair makes turbine wheel shaft idle running with the protection motor disengage from, and after motor was received reverse signal, the two ends of connecting rod were at the compression spring, or under the shell fragment effect, screw thread pair were meshed again.After steering wheel rotating shaft notch misalignment locking bolt was just locked motion, the compression spring absorbed the stroke that stretches out of locking bolt earlier, and when the steering wheel rotating shaft was rotated after a while, locking bolt will spring into steering wheel rotating shaft notch automatically under the compression spring action, realize locking.
