DETAILED DESCRIPTION OF THE PRESENT DISCLOSURE
The present disclosure discloses a protected keyless lock. The protected keyless lock is provided in the vehicle for the locking and unlocking of the vehicle or its components. The protected keyless lock protects the vehicle from unauthorised use and theft. The protected keyless lock comprises a housing, a solenoid assembly, a solenoid plate and an electronic control unit. The housing is provided to accommodate one or more components of the protected keyless lock. The solenoid assembly is placed inside the housing. The solenoid assembly is secured in the housing to prevent tempering with the solenoid assembly for protecting the vehicle from unauthorised use. The electronic control unit is at least partially placed inside the housing. The electronic control unit is provided to send signal to the solenoid assembly while user operates the lock. The solenoid assembly receives the signal and retracts a solenoid lever that causes the linear movement of a lock bar for locking and unlocking of the vehicle.

Accordingly, the present disclosure provides a protected keyless lock. The protected keyless lock is described with reference to the figures and alternative embodiments; this description is not meant to be constructed in a limiting sense.
Referring to the figure 1 which illustrates the exploded view of a protected keyless lock. The protected key less lock comprises a housing (2), a solenoid assembly (4), a solenoid plate (6), a back cover (12), a base assembly (28), a carrier assembly (30), an electronic control unit (14) and a knob (18). The housing (2) is configured to accommodate one or more components of the protected keyless lock (100). The housing comprises a first rim (201) for supporting the solenoid plate (6). A second rim (402) is provided in the housing (2) to accommodate the back cover (12). The housing (2) comprises a second plurality of side walls (48). The second plurality of side walls may extend integrally with the housing and may be configured to cover the components placed in the housing.
Referring to the figure 2 and 3, the knob (18) is provided for the user to execute the locking and unlocking of the vehicle. The knob (18) is connected to a knob rotor (22) through a knob ring (20). A plurality of the knob balls (1802) and a knob spring (1804) are placed between the knob ring (20) and the knob rotor (22) to form an excessive torque protection mechanism. Whenever excessive torque is applied on the knob (18), the plurality of the knob balls (1802) compresses the knob spring (1804) and moves inside the knob rotor (22) for breaking with the contact between the knob ring (20) and knob (18). This causes the free rotation of the knob (18) and protects the vehicle from unauthorised unlocking with application of excessive force/torque on the knob (18). Further, the knob rotor (22) is connected with a rotor (32) to transfer rotary motion of the knob (18) to rotor (32).
Referring to the figure 1, the rotor (32) is connected to a BLB (33). The BLB (33) converts the rotary motion of the rotor (32) into the linear motion. The BLB (33) is further connected with a lock bar (34) to transmit the linear motion to the lock

bar (34) for retracting or extending the lock bar. The rotor (32) is passed through a slot provided on the base assembly (28). Further, the carrier assembly (30) is connected with the bottom portion of the rotor (32). The carrier assembly (30) rotates along with the rotor (32) and forms electrical connection with the base assembly (28) to initiate the ignition of the vehicle engine. An inner cover (38) is provided to cover the base assembly (28) from the adjacent sides. The carrier assembly (30) is covered by the bottom cover (36) from bottom.
Referring to the figure 4, a plunger (24) is placed below the knob (18). The plunger comprises an extended portion (42) wherein the bottom surface of the extended portion (42) is placed over a microswitch (26). The microswitch (26) is connected with the electronic control unit (14) to activate the same.
Referring to figure 5 and 6, the electronic control unit (14) is at least partially placed in the housing (2) from the bottom side. The electronic control unit (14) is connected with the solenoid assembly (4) by a solenoid connecting wire (16). The knob (18) presses the plunger (17) which further presses the microswitch (26) to activate the electronic control unit (14). The electronic control unit (14) searches for the authentic key in the vicinity. As the key is found, the electronic control unit (14) sends a signal to the solenoid assembly (4) by the solenoid connecting wire (16) for locking and unlocking of the vehicle. The electronic control unit (14) is partially covered by an electronic control unit plate (40).
Referring to figure 7 and 8, the solenoid assembly (4) is placed inside the housing (2) to receive a signal from the electronic control unit (14) for locking and unlocking of the vehicle. The solenoid assembly (4) is connected to a solenoid lever (401). The solenoid lever (401) having two ends; one end is connected with the solenoid assembly (4) and another end is connected with a solenoid spring (402). As the solenoid assembly (4) receives the signal from the electronic control unit (14), retracts the solenoid lever (401) for engaging and disengaging it from the rotor (32).

Referring to figure 9, the solenoid plate (6) is attached with the first rim (201) of the housing (2) for covering the solenoid assembly (4) to prevent tempering of it. The solenoid plate (6) conceals the solenoid connecting wire (16) to protect it from any unauthorised application for unlocking or locking of the vehicle. The solenoid plate (6) is secured with the housing (2) by a plurality of screws (8) having antitheft heads (10). After tightening of the plurality of screws (8) over the solenoid plate (6), the antitheft heads are broken off for the permanent attachment of the solenoid plate (6) with the housing (2). The plurality of screws (8) with broken antitheft heads are permanently fastened that cannot be removed. This permanent attachment prevents the removal of the solenoid plate (6) by unscrewing of the plurality of screws (8). In a non-limiting embodiment of the present disclosure, two screws (8) are used to secure the solenoid plate (4) with the housing (2). The solenoid plate (6) covers the electronic control unit (14) inside the housing (2). In an embodiment, the solenoid plate (6) partially covers the electronic control unit (14) inside the housing (2). In another embodiment, the solenoid plate (6) entirely covered the electronic control unit (14) inside the housing (2). In one more embodiment, the solenoid plate (6) covers a mounting portion (46) of the electronic control unit (14) with the housing (2).
Referring to figure 1,10 and 11, the back cover (12) is attached with the second rim (202) of the housing (2) to cover the solenoid plate (6) as well as solenoid assembly (4). The back cover (12) comprises a base surface (42) and a first plurality of side walls (44) extending integrally from the base surface. The contour of the back cover (12) is overlapped with the contour of the second rim (202) for attachment. In an embodiment, the back cover (12) has at least three side walls (44) for covering the housing (2) and components placed in the housing (2). The first plurality of side walls (44) at least partially cover the second plurality of side walls (48). In the embodiment as show, the first plurality of side walls almost entirely cover the second plurality of side walls. This provides a double layer protection to the solenoid assembly (4). The back cover (12) also prevents the plurality of screws

(8). The location of the plurality of screws (8) tighten on the solenoid plate (6), is away from the mounting location of the back cover (12). Even if the back cover (12) is broken, the solenoid plate (12) would prevent direct access to the solenoid connecting wire (16) of the solenoid assembly (4). Accordingly, the back cover (12) provides an additional protection to the solenoid assembly (4).
In an embodiment of the present disclosure, the housing (2), the solenoid plate (6) and back cover (12) may be made of any high strength materials such as metals, polymers, etc.
The operation of the protected keyless lock from lock to unlock condition is described as follows. The user presses the knob (18) for unlocking the handlebar of the vehicle. The knob (18) presses the plunger (24) which in turn presses the micro switch (26) and activates the electronic control unit (14). The electronic control unit (14) searches for the authentic electronic key in the vicinity. If the authentic key is found, the electronic control unit (14) sends a signal to the solenoid assembly (4) to retract the solenoid lever (401) and disengaged it from the rotor (32) as shown in figure 7. This allows the rotation of the rotor (32) along with the knob (18). The pushing and further rotation of the knob (18) towards unlock position, rotates the rotor (32) along with it. The BLB (33) converts the rotary motion of rotor (32) into linear motion and provides that linear motion to the lock bar (34). This retracts the lock bar (34) inside the housing (2), hence unlocks the vehicle. The solenoid lever (401) of solenoid assembly (4) returns back to its original state through the spring (402) after a predetermined time as shown in figure 6, thereby prohibiting the rotary motion of knob (18) and rotor (32). In an embodiment of the present disclosure, the unlocking of the handlebar allows the vehicle for authorised use.
The operation of the protected keyless lock from unlock to lock condition is described as follows. The user presses the knob (18) for unlocking the handlebar of the vehicle. The knob (18) presses the plunger (24) which in turn presses the

micro switch (26) and activates the electronic control unit (14). The electronic control unit (14) searches for the authentic electronic key in the vicinity. If the authentic key is found, the electronic control unit (14) sends a signal to the solenoid assembly (4) to retract the solenoid lever (401) and disengage it from the rotor (32) as shown in figure 7, hence allowing the knob (18) and rotor (32) to rotate. The pushing and further rotation of the knob (18) towards lock position, rotates the rotor (32) along with it. The BLB (33) converts the rotary motion of rotor (32) into linear motion and provides that linear motion to the lock bar (34). This moves the lock bar (34) outside the housing (2), hence locks the handlebar of the vehicle. The solenoid lever (401) of solenoid assembly (4) returns back to its original state through the spring (402) after a predetermined time as shown in figure 6, thereby prohibiting the rotary motion of knob (18) and rotor (32). In an embodiment of the present disclosure, the locking of the handlebar protects the vehicle from unauthorised use.
Accordingly, the present disclosure provides a protected keyless lock for vehicle that prevents the tempering of the solenoid connecting wire (16) and direct access to the solenoid assembly (4) for protecting the vehicle from unauthorised locking and unlocking.
