“A LOCKING DEVICE FOR A VEHICLE”
Name and Address of the Applicant: Minda Corporation Limited, an Indian citizen of E-5/2, Chakan Industrial Area, Phase- III M.I.D.C. Nanekarwadi, Tal: Khed, Dist., Pune, Maharashtra, 410501, India
The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD
[001] The present disclosure generally relates to the field of automobiles. Particularly, but not exclusively, the present disclosure relates to a locking device for a vehicle that is capable to lock or unlock a steering column of the vehicle.
BACKGROUND OF THE DISCLOSURE
[002] The information in this section merely provides background information related
to the present disclosure and may not constitute prior art(s) for the present disclosure.
[003] Vehicles such as, but not limited to, two-wheelers, three-wheelers, four-wheelers, and the like are nowadays provided with keyless system. The keyless system includes a steering lock and remote control unit (which includes smartphone, keyfob, or any device capable to transmit radio waves). The remote control unit is activated by the user to enable the steering lock to lock or unlock the steering column of the vehicle. Conventionally, steering lock includes a motor that is powered by a storage battery of the vehicle to drive the lockbolt through an actuation system. The actuation system is connected to the lockbolt at one side and connected to the motor at the other side. The actuation system is driven by the motor and it further drives the lockbolt to lock or unlock the steering column. The actuation system is a gear train arrangement that produces the required torque to actuate the lockbolt. However, the conventional gear train arrangement includes a plurality of gears that acquires large space in relation to the motor and the lockbolt. Further, the motor and the gear train arrangement when packaged as a single unit increases the overall size of the motorized steering lock. The increase in size of the unit causes to increase in the volume of the entire package which further prevents achieving required clearances from the surrounding parts at the steering column in the vehicle. The reduced clearance prevents the fitment of the steering lock at the steering column to achieve proper locking and unlocking.
[004] Further, the lockbolt locks the steering column by blocking the rotation of the steering column, thereby the position of the lockbolt is fixed with respect to the vehicle and steering column requirements. Based on the fixed position of the lockbolt, the motor and the plurality of gear trains are located which produces constraints in respect of the design aspects and provides insufficient torque to the lockbolt. This affects the

overall operation of locking or unlocking the steering column of the vehicle, which is not desirable.
[005] With the advent of the technologies of vehicles, manufacturing companies are providing compact vehicles. Accordingly, there is a requirement to optimize the size of the lock unit which can be placed even in space constraint areas of the vehicle. It is challenging to develop a lock unit that is compact, produces high torque, and is capable to be positioned irrespective of the position of the lock bolt.
[006] The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the prior art.
