Improvement in Automotive Locks Inventor Mr. PRASHANT PARASHURAM SATHE

Technical Field of Invention This invention helps in achieving a better security standard for vehicle protection by means of an electro – mechanical automative lock. Existing systems use conventional locking system which is easier to break open. This invention helps in achieving a higher level of advanced protection measure for the security of the vehicle in a very economical cost and overcomes the shortcomings of the current conventional locks in practice.

It provides flexibility for the modification as per requirements. Involvement of investor's Research and Development expertise, would further enhance the quality of product.

The Problem Mobility is one of the most basic needs of humankind. With time, people have developed “means” in order to move from one place to another. With private ownership of such means, a newfound challenge is created with regard to security of such means. High monetary value of such private means increased chances of theft. These means in the contemporary world include automobiles such as cars and motorcycles. Further, this problem has been aggravated with better techniques of dissembling such automobiles. Although numerous attempts have been made till date in order to safeguard these automobiles by way of locking system/ mechanism which has further been developed with time. However, owing to potential rewards, both frequency and proficiency of theft has increased. And conventional locks were proved to be significantly insufficient as vehicle protection measures. As a consequence, a breakthrough was much awaited that would increase the odds of breaking open of a vehicle safety lock. Prevention or Cure? Which is better? To find your stolen vehicle? or To safeguard your vehicle against theft? Is it possible to provide better protection to your vehicles? HOW?

Conventional Technology The conventional automobile lock generally has two functions. First, as an electrical switch. And second, as a handle lock. Even though these locks need a key with a unique physical pattern to open up, the switch function of these conventional locks are simply bypassed by cutting the wire outside of a lock and connecting them directly. Due to this ignition’s electrical circuit gets closed and allows engine of such automobile to start. On the other hand, considering handle lock function of such conventional lock, it is observed that the handle/steering of bike/car is locked at certain position with help of mechanical blockage. When handle is locked, certain mechanical element from lock protrudes and gets interlocked physically with certain interlocking element which is rigidly fixed to automobile chassis/body directly or indirectly. Due to this the movement, rotation of bike/car handle/steering is restricted making the automobile non drivable. But still this handle lock is easily broken by thieves by applying huge angular torque manually on bike/car’s handle/steering. Conventional Lock Two functions Electrical switch Handle lock Failure in Conventional Locking System Electrical switch: Bypass Handle lock: Angular torque Electronic authentication – Prone to HACKING !!! Need: Increase theft resistance of vehicles

Working Overview This invention provides a novel mechanism for electro – mechanical authentication for locking system/ mechanism. “Normally – open” circuit which is in a locked position when the circuit is open and requires special mechanical arrangement to close the circuit and to open the lock after successful authentication. The lock comprises of cylindrical pins that give physical push to all open switches in order to complete circuit. These locks have high standard of encryption and mere observation fails to break open the lock. Handle lock consists of a spring and wedge system which requires high angular torque to give way.

In Depth Working Illustration of configuration of lock when handle lock is enabled: Low tension springs get compressed whereas high tension spring does not. This leads to change in orientation of position of mechanical cam. On applying rotational torque, interlocking elements of lock and chassis will strike each other. The interlocking element of the lock is provided with a wedge/ taper such that the force applied will cause the interlocking element of the chassis to move into the lock casing. After force is withdrawn, due to wedging action, the element will move away from each other thereby remaining intact and unharmed. The number of fixed interlocking elements can be increased across the path travelled by interlocking element of automotive lock when handle/steering is rotated.

In Depth Working Illustration of configuration of lock when handle lock is disabled: The circuit is in closed state. Due to this, the spring loaded solenoid actuator will be triggered on receiving power from battery and will push the solenoid pin outwards. After inserting key, the knob coupled with the slotted pin is rotated manually. This slotted pin passes into casing through small hole provided in casing. A time will come when the position of slot of slotted pin will match with the solenoid pin interlocking the two. Now, when rotated, the knob will also rotate the solenoid. The solenoid is coupled with a mechanical cam through a ring. Hence the cam will also rotate. As the cam rotates, its extension will push the thick metal plate which will exert force on the high tension spring. The high tension spring will pass on the force received to the second metal plate which further transfers it to low tension spring. Through the second metal plate along with low tension spring, the interlocking element of the lock will move out and get itself fixed with the interlocking element of the chassis thereby restricting the free movement of the handle/steering.

System Authentication Detailed Explanation To unlock, authenticating system of lock to be authenticated: Figure illustrates mechanism of authentication system. For this, the key having a unique pattern of point extrusions similar to the corresponding pins in the lock must be inserted into the key way. Due to this, the corresponding pins will be closed completing the circuit and the automobile’s ignition with electrical utilities and solenoid actuator will get electrical power for their functioning. The system will be in sealed and opaque enclosure casing of very thick and strong metal and only key way is open to outside for key entry. Unlike conventional lock there is no physical variation in key way since all the end of pins extruded in key way are of uniform physical characteristics. The encryption strength will increase with the number of switches. It can be provided with provisions for handle/steering lock for restricting the free movement of handle/steering of bike/car.
