CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
[0001] The present application claims priority from Indian provisional patent application no. 202221019097, filed on March 30, 2022. The entire contents of the aforementioned application are incorporated herein by reference.

FIELD OF THE INVENTION
[0002] The present invention generally relates to a field of automobiles. Particularly, but not exclusively, the present disclosure relates to a wiper blade lifting system for a vehicle.

BACKGROUND OF THE INVENTION
[0003] Typically, in a vehicle park position, a wiper blade of a wiper assembly for a vehicle is rested against a windshield. In such position of the wiper blade on the windshield, due to constant contact of the wiper blade with the windshield, environmental elements like dust, vehicle waxes, oils, moisture and airborne debris gets trapped between a wiper rubber of the wiper blade and the windshield glass. This results into deterioration and subsequent cracking of a wiper rubber, thereby resulting in a frequent and high-cost replacement of the wiper blade. Further, this also induces performance issues of the wiper assembly and thereby leading to poor visibility to a user/driver of the vehicle during a vehicle driving condition. Also, during rainy season, water logging near wiper blades takes place and these further damages the wiper rubber.
[0004] The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the known arts.

OBJECTS OF THE INVENTION
[0005] The principal object of this invention is to provide a wiper blade lifting system to ensure that the wiper blade is not in contact with the windshield glass when vehicle is in ignition OFF state.
[0006] Another object of this invention is to provide a wiper blade lifting system to improve life of wiper blade.
[0007] Another object of this invention is to provide a wiper blade lifting system to reduce damage, deterioration and cracking of wiper rubber.

SUMMARY OF THE INVENTION
[0008] Before the present system are described, it is to be understood that this application is not limited to the particular machine or an apparatus, and methodologies described, as there can be multiple possible embodiment that are not expressly illustrated in the present disclosure. It is also to be understood that the terminology used in the description is for the purpose of describing the particular version or embodiment only and is not intended to limit the scope of the present application. This summary is provided to introduce aspects related to a wiper blade lifting system and the aspects are further elaborated below in the detailed description. This summary is not intended to identify essential features of the proposed subject matter nor is it intended for use in determining or limiting the scope of the proposed subject matter.
[0009] In one non-limiting embodiment of the disclosure, a wiper blade lifting system includes a wiper blade lifting mechanism comprising a lifting means and an actuating means. The lifting means further comprises a wedge member mounted on the second wiper-arm portion of the wiper assembly. The actuating means comprises of a solenoid actuator and a plunger assembly including a plunger member and a roller mounted on the plunger member. The plunger member of the plunger assembly is supported by a guided groove member being disposed in a first wiper arm portion of the wiper arm. Further, the solenoid actuator is mounted on the first wiper arm portion. Furthermore, the roller is rested on the wedge member.
[0010] In an embodiment, during an ignition on-condition, a vehicle battery is configured to supply electrical power to actuate the solenoid actuator. Upon actuation, the solenoid actuator retracts the plunger member along with the roller to change a wiper blade position from a lifted/ raised wiper blade position to a non-lifted/ lowered wiper blade position. In an illustrated embodiment, the first wiper arm portion and the second wiper arm portion are hingedly connected through a hinged member.
[0011] In an embodiment, the first wiper arm portion and the second wiper arm portion are hingedly connected through a hinged member such that the wiper blade swings about a hinge axis (YY’) when shifting from the lifted/ raised wiper blade position to the non-lifted/ lowered wiper blade position and vice-versa.
[0012] In an embodiment, the solenoid actuator, upon actuation, operates the plunger assembly such that the roller being connected to the plunger member, is further actuated to shift from a lift wiper blade position to the non-lift wiper blade position on the wedge member.
[0013] In an embodiment, during an ignition off-condition for the vehicle, the solenoid actuator is deactivated such that the plunger member along with the roller is extended to change the wiper blade position from a second predetermined position to the first predetermined position. The second predetermined position of the wiper blade is the lifted/ raised wiper blade position such that the roller is at the lifted/ raised wiper blade position on the wedge member. At the lifted/ raised position, the wiper blade is disposed away from the windshield of the vehicle and along a line CC’. That is, in shifting condition of the wiper blade from the non-lifted/ lowered blade position to the lifted/ raised blade position, the wiper blade position is shifted from the plane AA’ to the line CC’ along a vehicle transverse axis. More specifically, upon deactivation of the solenoid actuator and during the lifted/ raised wiper blade position the roller being connected to the plunger member shifts from the non-lift/ lowered wiper blade position to the lifted/ raised wiper blade position.
[0014] The foregoing summary is illustrative only and is not intended to be in any way limiting. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features will become apparent by reference to the drawings and the following detailed description.

In an illustrated embodiment, during an ignition on-condition, a vehicle battery is configured to supply electrical power to actuate the solenoid actuator (200). Upon actuation, the solenoid actuator (200) is configured to retract the plunger member (201) along with the roller (203) by a predetermined distance to change the position of the roller (203) from a lifted/ raised wiper blade position (401) to a non-lifted/ lowered wiper blade position (400) on the wedge member (shown in Figures 4a and 4b). In an illustrated embodiment, the first wiper arm portion (104a) and the second wiper arm portion (104b) are hingedly connected through a hinged member (206).
[0032] Figure 3 illustrates an enlarged bottom view of the at least a portion of the wiper assembly (105) illustrating the wiper blade lifting mechanism (100) for the vehicle, in accordance with an embodiment of the present invention. In an illustrated embodiment, the wiper blade lifting mechanism (100) comprises the wedge member (202), the solenoid actuator (200) and the plunger assembly (207) including the plunger member (201) and the roller (203) fixedly attached to plunger member (201). The plunger assembly (207) is supported by the guided groove member (205) mounted on the first wiper arm portion (104a) of the wiper arm (104). Further, the wiper blade lifting mechanism (100) comprises the solenoid actuator (200) mounted on the first wiper arm portion (104a). In particular, the solenoid actuator (200) is operatively connected to the plunger assembly (207). That is, during an ignition on-condition, a vehicle battery is configured to supply electrical power to actuate the solenoid actuator (200). Upon actuation, the solenoid actuator (200) is configured to retract the plunger assembly (207) by a predetermined distance to change the position of the roller (203) from the lifted/ raised wiper blade position (401) to the non-lifted/ lowered wiper blade position (400) on the wedge member (202) (shown in Figures 4a and 4b). In an illustrated embodiment, the first wiper arm portion (104a) and the second wiper arm portion (104b) are hingedly connected through a hinged member (206) such that the wiper blade (102) swings about a hinge axis (YY’) when shifting from the lifted wiper blade position (401) (shown in Figures 4a and 4b) to the non-lifted wiper blade position (400) and vice-versa.
[0033] Figure 4a illustrates a side view of the at least a portion of the wiper assembly (105) illustrating a non-lifted wiper blade position of the wiper blade (102), in accordance with an embodiment of the present invention. In an illustrated embodiment, the wiper blade lifting mechanism (100) includes the wedge member (202), the solenoid actuator (200) and the plunger assembly (207). Further, the wiper blade lifting mechanism (100) includes the solenoid actuator (200) mounted on the first wiper arm portion (104a). In particular, the solenoid actuator (200) is operatively connected to the plunger assembly (207). During an ignition on-condition for the vehicle, the vehicle battery is configured to supply an electrical power to actuate the solenoid actuator (200). Upon actuation, the solenoid actuator (200) is configured to change a first predetermined position of a wiper blade (102) to the non-lifted wiper blade position (400). In an illustrated embodiment, the first predetermined position of the wiper blade (102) is a lifted wiper blade position that a roller (203) is at a lifted wiper blade position (401). At the non-lifted position, the wiper blade (102) is disposed against the windshield (101) of the vehicle. In an illustrated embodiment, at the non-lifted wiper blade position, the wiper blade (102) is positioned along a plane AA’. More specifically, the solenoid actuator (200), upon actuation, operates the plunger assembly (207) such that the roller (203) being connected to the plunger member (201) is further actuated to shift from a lifted wiper blade position (401) to the non-lifted wiper blade position (400). In an illustrated embodiment, the first wiper arm portion (104a) and the second wiper arm portion (104b) are hingedly connected through a hinged member (206) such that the wiper blade (102) swings about a hinge axis (YY’) when shifting from the lift wiper blade condition (401) to the non-lift wiper blade position (400) and vice-versa.
[0034] Figure 4b illustrates a side view of the at least a portion of the wiper assembly (105) illustrating a lifted wiper blade condition of the wiper blade (102), in accordance with an embodiment of the present invention. In an illustrated embodiment, the wiper blade lifting mechanism (100) includes the wedge member (202), the solenoid actuator (200) and the plunger assembly (207). Further, the wiper blade lifting mechanism (100) includes the solenoid actuator (200) mounted on the first wiper arm portion (104a). In particular, the solenoid actuator (200) is operatively connected to the plunger assembly (207). During an ignition off-condition for the vehicle, the solenoid actuator (200) is deactivated such that the wiper blade (102) position is changed from a second predetermined position to the first predetermined position. In an illustrated embodiment, the second predetermined position of the wiper blade (102) is the non-lifted wiper blade condition such that a roller (203) is at the non-lifted wiper blade position (400). In the illustrated embodiment, at the lifted position, the wiper blade (102) is disposed away from the windshield (101) of the vehicle and along a line CC’. That is, in a shifting condition of the wiper blade (102) from the non-lifted blade position (400) to the lifted blade position (401), the wiper blade position is shifted from the plane AA’ to the line CC’ along a vehicle transverse axis. More specifically, upon deactivation of the solenoid actuator (200) (shown in Figure 3) and during the lift-wiper blade condition the roller (203) being connected to the plunger member (201) shifts from the non-lifted wiper blade position (400) to the lifted wiper blade position (401).
[0035] Further, in an illustrated embodiment, the first wiper arm portion (104a) and the second wiper arm portion (104b) are hingedly connected through a hinged member (206) such that the wiper blade (102) swings about a hinge axis (YY’) when shifting from the lifted wiper blade position to the non-lifted wiper blade position and vice-versa.
[0036] Advantageously, the disclosed wiper lifting mechanism (100) facilitates in shifting the position of the wiper blade (102) from the non-lifted position to the lifted position, thereby lifting the wiper blade in a predetermined position such that the wiper blade (102) is lifted away from the windshield (101). This eliminates the constant contact of the wiper blade (102) with the windshield (101), thereby preventing damage to the windshield (101) and additionally enhancing life of the wiper blade (10) by reducing the frequent high-cost replacement thereof.
[0037] Figure 5 is a sectional view of the at least a portion of the wiper assembly (105) when taken along a longitudinal axis (XX’) thereof, in accordance with an embodiment of the present invention. An illustrated embodiment illustrates the non-lifted wiper blade position (400). At non-lifted wiper blade position (400), the solenoid actuator (200) is actuated. Upon actuation, the solenoid actuator (200) is configured to change a predetermined position of a wiper blade (102) from a lifted wiper blade position (401) to the non-lifted wiper blade position (400). In an illustrated embodiment, the first wiper arm portion (104a) and the second wiper arm portion (104b) are hingedly connected through a hinged member (206) such that the wiper blade (102) swings about a hinge axis (YY’) when shifting from the lifted wiper blade position (401) (shown in Figures 4a and 4b) to the non-lifted wiper blade position (400) and vice-versa.
[0038] In an embodiment, a method of lifting and lowering the wiper blade (102) is explained. When ignition is turned ON, electric power is supplied by the battery to actuate the solenoid actuator (200). Upon actuation, the solenoid actuator (200) retracts the plunger member (201) along with the roller (203) to move the roller from lifted position (401) to non-lifted position (400) on the wedge member (202). When the roller (203) changes its position from lifted position (401) to non-lifted position (400), the wiper blade (102) swings about a hinge axis (YY’) towards the windshield (101) till the wiper blade (102) rests on the windshield (101). When the ignition is turned OFF, the supply of electrical power to the solenoid actuator (200) is interrupted and the solenoid actuator (200) extends the plunger member (201) along with the roller (203) to move the roller from the non-lifted position (400) to the lifted position (401) on the wedge member (202). When the roller (203) changes its position from the non-lifted position (400) to the lifted position (401), the wiper blade (102) swings about a hinge axis (YY’) away from the windshield (101) to create a gap between the wiper blade (102) and the windshield (101).
[0039] Accordingly, present invention discloses a wiper blade lifting system comprising a wiper assembly (105) and a wiper blade lifting mechanism (100) configured with a lifting means and an actuating means to lower and lift a wiper blade (102) of the wiper assembly (105) from windshield (101). The lifting means comprises a wedge member (202) mounted on a second wiper-arm portion (104b) of the wiper assembly (105) configured to form integral part of the second wiper-arm portion (104b) and the actuating means configured with a roller (203) and a plunger member (201) assembly mounted on a solenoid actuator (200). The roller (203) is configured to rest on the wedge member (202). The plunger member (201) is configured to be intermediately supported by a guided groove member (205) on a first wiper arm portion (104a) of the wiper assembly (105). The solenoid is configured to retract the plunger member (201) along with the roller (203) by a predetermined distance, upon turning ON the ignition for lowering the wiper blade (102) to rest on windshield (101). The solenoid is configured to extend the plunger member (201) along with the roller (203) by a predetermined distance, upon turning OFF the ignition for lifting the wiper blade (102) away from windshield (101). The roller (203) is adapted to provide pivotal movement to the second wiper-arm portion (104b) about hinge axis (YY’) for lowering the wiper blade (102). a vehicle battery is configured to supply electrical power to actuate the solenoid actuator (200) of the actuating means, in ignition ON-condition. The roller (203) is adapted to provide pivotal movement to the second wiper-arm portion (104b) about hinge axis (YY’) for lifting the wiper blade (102).
[0040] The present invention further discloses method for lifting and lowering a wiper blade (102) comprising steps of turning ON vehicle ignition; supplying electrical power by a battery to actuate a solenoid actuator (200); retracting a plunger member (201) along with a roller (203) by the solenoid actuator (200) to change position of the roller (203) from lifted position (401) to non-lifted position (400) on a wedge member (202), wherein the wiper blade (102) is lowered on a windshield (101); turning OFF vehicle ignition; deactivating the solenoid actuator (200); and extending the plunger member (201) along with the roller (203) by the solenoid actuator (200) to change position of the roller (203) from non-lifted position (400) to lifted position (401) on the wedge member (202), wherein the wiper blade (102) is raised from the windshield (101).
