[064] Referring to Figures 7a-8b, the initial and the actuated position of the parking brake device (20) are depicted. In the initial position, the brake lever (13) is not pressed and the vehicle lock unit (16) is not operated by the user for applying parking brakes on the vehicle (100), as shown in Figure 7a and 7b. The vehicle lock unit (16) comprises a lock lever (16a) configured to actuate the parking brake device (20) of the vehicle (100), by rotation of vehicle key by the user. Alternatively, the actuation of lock lever (16a) is governed by an actuator which is triggered by means of a switch provided on the handle bar (114) of the vehicle (100). The position of the switch may vary depending on the aesthetics and comfort for the user to apply parking brakes on the vehicle (100). The lock lever (16a) is connected to an end of the lock cable (17).
[065] In the initial position, the slider (22) is positioned at the left most position within the channel (21a) of the body (21) and the bracket (23) abuts against an inner surface of the flange (21f), via biasing force of the spring (25) in outward direction or in a direction away from the slider (22). While applying, the rear brakes on the vehicle during driving condition of the vehicle, the brake lever (13) is pulled, the pulling force is transmitted to the slider (22) by the first brake cable (14). The first brake cable (14) connected to the slider (22) by the first connector (14c), exerts pulling force on the slider (22). The slider (22) slides from the left most position to the right most position. The sliding movement of the slider (22) transmits the pulling force to the rear wheel brake unit (12a) by the second brake cable (15), thereby actuating the rear wheel brake unit (12a) of the vehicle (100).
[066] In an exemplary embodiment, a method for operating a parking brake device (20). The method comprises - pulling of a brake lever (13) to facilitate actuation of a rear wheel brake unit (12a) mounted on a rear wheel (12) of a vehicle (100). The next step is to rotate a key inserted in a vehicle lock unit (16) in a predefined direction to transmit a pulling force on a bracket (23) of the parking brake device (20) through a lock cable (17). The rotation of the key facilitates engaging the at least one locking arm (23b) of the bracket (23) with a slider (22) of the parking brake device (20) and thereby actuating the parking brake device (20) for parking the vehicle (100).

[067] Referring to Figure 8b, the rotating of the key facilitates in pivotal movement of the lock lever (16a). The pivotal movement of the lock lever (16a) exerts a pulling force on the bracket (23) via the inner wire (17a) of the lock cable (17). The pulling on the bracket (23) facilitates sliding movement of the bracket (23) towards the slider (22). The sliding movement of the bracket (23) facilitates insertion of the locking arm (23b) into the at least one slot (22a) provided in the slider (22). The insertion of the locking arm (23b) or engagement of the locking arm (23b) with the slider (22), thereby facilitating locking of the slider (22) in the actuated position, as shown in Figure 8a.
[068] In another exemplary embodiment, a method for de-actuating the parking brake device (20) is disclosed. The parking brake device (20) is de-actuated only by rotation of the key in opposite direction or pressing of the switch for governing the actuator. The rotation of the key in opposite direction facilitates downward or pivotal movement of the lock lever (16a) thereby releasing tension in the inner wire (17a) of the lock cable (17). Once, the tension is released, the spring (25) exerts a biasing force on the bracket (23) in a direction away from the slider (22), thereby disengaging the bracket (23) from the slider (22). Then, the brake lever (13) automatically moves from the actuated position to the initial position and the rear wheel brake unit (12a) is de-actuated, thereby de-actuates or releases the parking brakes on the vehicle (100).
[069] In an embodiment of the present disclosure, the parking brake device facilitates actuating and releasing of the parking brakes by means of a vehicle key.
[070] In an embodiment of the present disclosure, the parking brake device provides theft protection of the vehicle.
[071] In an embodiment of the present disclosure, the parking brake device improves safety of the vehicle.
