Abstract
The utility model discloses an unlocking auxiliary mechanism of an electronic steering column lock. The unlocking auxiliary mechanism can improve unlocking force of the electronic steering column lock, reduce unlocking response time, reduce noise during traveling and reduce probability of locking of a vehicle during traveling. Worm and worm gear transmission is formed by a worm assembled on a motor shaft and a plastic helical gear assembled between an upper casing and a lower casing, screw transmission is formed by internal threads inside the plastic helical gear and external threads on a sliding block, a bolt is driven by a plastic covered draw bar on the sliding block to do rectilinear motion, an unlocking spring is arranged, a lower end of the unlocking spring is supported on the lower casing, and an upper end of the unlocking spring is pressed by the sliding block.
Description
Technical field
The utility model relates to a kind of release auxiliary mechanism of electronic steering column lock, is used for the release of electronic steering column lock.
Background technology
Electronic steering column lock is a kind of novel product that substitutes traditional mechanical steering post lock, and it mainly cooperates intelligent key system or uses without the key start-up system.Electronic steering column lock relies on the motor of self and mechanism to carry out the release action of locking fully, and finishing release is the necessary condition that starts engine, therefore, whether can be in time smoothly release become one of key factor that affect the car load startup.And the releasing force of electronic steering column lock and release response time become most important two performance figure.Most of electronic steering column lock releasing force and response time that can provide is all lower in the market.Therefore, may be stuck in the releasing process, or respond bluntly, finally cause engine to start, perhaps postpone.In addition, noise is very large in the time of also can causing driving.In addition, electronic steering column lock also is safety member.If rupture failure appears in inner body when driving, cause dead bolt to enter in the steering column, bearing circle is locked in the time of then can causing driving, directly jeopardizes chaufeur and passenger safety.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of releasing force that improves electronic steering column lock, reduces the release response time, the noise when reducing driving, be reduced in the release auxiliary mechanism of the electronic steering column lock of the probability that driving locks.
The technical scheme that addresses the above problem is: the release auxiliary mechanism of this electronic steering column lock, be assemblied in the worm screw on the motor drive shaft and be assemblied in upper shell and lower house between plastic beveled wheel consist of Worm and Worm Gear Driving, the negative thread of plastic beveled wheel inside and the outside thread on the slide block have consisted of screw drive, drive dead bolt by the plastic pull bar on the slide block and carry out straight-line motion, be provided with the release spring, its lower end is supported on the lower house and its upper end is pushed down by slide block.
Because in electronic steering column lock, be provided with the release spring, thus when electronic steering column lock is begun to carry out release by locking state, can provide counter-force to help the dead bolt overcome friction to help release, thus improve releasing force, reduction release response time; Under released state, the release spring still is in compressive state, and whole system is owing to being under the endogenetic process, so in the driving process, outside shock and vibration can not cause rocking of inner component, thereby can reduce the noise in the driving process; When driving, the counter-force of release spring can directly upwards promote dead bolt, thereby makes it more away from tubing string, avoids driving to lock.
Description of drawings
Fig. 1 is the structural representation of electronic steering column lock;
Fig. 2 is according to the structural representation of the release auxiliary mechanism of electronic steering column lock of the present utility model when released state;
Fig. 3 is according to the structural representation of the release auxiliary mechanism of electronic steering column lock of the present utility model when locking state.
Specific embodiments
As Figure 1-3, the release auxiliary mechanism of this electronic steering column lock, be assemblied in the worm screw 1 on the motor drive shaft and be assemblied in upper shell 8 and lower house 7 between plastic beveled wheel 2 consist of Worm and Worm Gear Driving, the negative thread of plastic beveled wheel 2 inside and the outside thread on the slide block 3 have consisted of screw drive, drive dead bolt 5 by the plastic pull bar 4 on the slide block 3 and carry out straight-line motion, be provided with release spring 6, its lower end is supported on the lower house 7 and its upper end is pushed down by slide block 3.
Preferably, also be provided with pad between the lower end of release spring and the lower house.
The beneficial effects of the utility model are as follows:
1. when electronic steering column lock was begun to carry out release by locking state, the power of the 80N that the release spring provides can help the dead bolt overcome friction, thereby reached the raising releasing force, reduced the release response time.The releasing force of ordinary electronic lock for steering column between the 150N, and relies on this design at 85N, can be increased to about 200N.The release response time of ordinary electronic lock for steering column (non-loaded, normal temperature is under the 12V condition) relies on this design to be reduced to below the 180ms about 300ms.
2. under released state, the release spring still is in compressive state, and the counter-force that provides is 40N.Whole system is owing to being under the endogenetic process, so in the driving process, outside shock and vibration can not cause rocking of inner component, thereby can reduce the noise in the driving process.
3. in addition, the existence of release spring is very helpful for improving Security of the system.
Suppose not have the existence of release spring, the tooth fracture of worm tooth fracture, plastic gear, worm-gears can't self-lockings, the negative thread failure of plastic gear, the outside thread failure of slide block can cause dead bolt to enter tubing string inside, thus the safety problem that causes driving to lock.When having the release spring to exist, so the safety of whole system improves greatly.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction; any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment all still belong to the protection domain of technical solutions of the utility model.
Claims (2)
1. the release auxiliary mechanism of an electronic steering column lock, be assemblied in the worm screw (1) on the motor drive shaft and be assemblied in upper shell (8) and lower house (7) between plastic beveled wheel (2) consist of Worm and Worm Gear Driving, the negative thread that plastic beveled wheel (2) is inner and the outside thread on the slide block (3) have consisted of screw drive, drive dead bolt (5) by the plastic pull bar (4) on the slide block (3) and carry out straight-line motion, it is characterized in that: be provided with release spring (6), its lower end is supported on lower house (7) upward and its upper end is pushed down by slide block (3).
