APPLICANT:
TVS MOTOR COMPANY LIMITED, an Indian Company at: “Chaitanya”, No.12 Khader Nawaz Khan Road, Nungambakkam, Chennai 600 006.
The following specification particularly describes the invention and the manner in which it is to be performed.
TECHNICAL FIELD
[0001] The present subject matter relates generally to a windshield assembly for a vehicle and a windshield thereof. More particularly but not exclusively, the present subject matter relates to a curved windshield assembly for a vehicle and a curved windshield.
BACKGROUND
[0002] The windshields, in conventional vehicles such as but not limited to three wheeled vehicles, are secured on to the body or body frame of the vehicle by using rubber beadings. The rubber beadings are an essential component for automotive requirements, providing the necessary support, grip and vibration damping for the windshields. The rubber beadings are heated, then the edges of the windshield are inserted into a U-shaped sectional profile of the rubber beadings. Putting the windshield into place requires physical effort thereby making entire assembly process inefficient and physically exhausting which also increases the time required for assembly during the manufacturing of the vehicle and during maintenance and replacement. Also, the processing of the rubber beading gives rise to increased assembly time and manufacturing costs. Further, the processing of the rubber beading requires specialized tools to elongate beading section so that it can be assembled on frame and this increases assembly cost.
[0003] In the conventional windshields, there are chances of gap between the glass and the rubber beading because of the surface waviness and profile deviation. Over time, the rubber beadings become hard and brittle due to exposure to extreme weather conditions causing development of cracks. These gaps and cracks allow an entry of the rainwater, leading to an issue of leakage.
[0004] Further, the windshield secured with the rubber beadings are not theft proof. The windshield can be easily pushed out of the frame of the vehicle, just by removing the rubber beadings, which make the windshield prone to theft.
[0005] In order to address the above issue, the windshields are fixed to the body frame of the vehicle by using various sealants. However, these sealants cannot be used with curved windshields such as in case of three wheeled vehicle, thereby limiting the utility of sealants to the flat windshields only. For the three wheeled vehicles, the curved windshields are preferred as the seat of the driver is positioned in the middle of the driver cabin. The curved windshields offer uninhibited visibility not only towards front sides but also towards the lateral sides of the vehicle, thereby enhancing the field of vision. Further, the need of using separate glass panels for different sides of the vehicles is done away with. Therefore, it becomes necessary to provide a secured mounting of the curved windshields, especially in three wheeled vehicle. The conventional curved profile of the windshields is not suitable to directly secure the windshields on to the body frame of the vehicle through sealants. Further, if the curve profile is not made properly the windshield will act as a lens causing disturbance and inconvenience in visibility of the driver of the vehicle.
[0006] In order to overcome the above cited drawbacks of the prior art, the present invention discloses a windshield assembly and a windshield thereof.

[0036] The embodiments of the present invention will now be described in detail with reference to an embodiment of to a windshield assembly (200) for a vehicle (100) and a windshield (201) thereof, along with the accompanying drawings. However, the disclosed invention is not limited to the present embodiments. The vehicle (100) is a two-wheeled type vehicle, a three wheeled vehicle or a four wheeled vehicle or a multi axle vehicle, or the like. In one of the embodiments of the present disclosure the vehicle (100) may be an Electric Vehicle (EV), a Hybrid Electric Vehicle (HEV), an Internal Combustion Engine (ICE) based vehicle and have components suitable for traction. In a preferred embodiment, the vehicle (100) is a three wheeled vehicle.
[0037] Figure 1 illustrates a side perspective view of the windshield assembly (200) with respect to a front direction (F) and a rear direction (R) of the vehicle (100, shown in Fig. 7). The front direction (F) and the rear direction (R) are shown by an axis F-R. The windshield assembly (200) comprises a windshield (201) and a frame unit (202). The windshield (201) comprises a linear portion (201L), a first curved portion (201F) and a second curved portion (201S). The linear portion (201L) is provided with a linear profile. The first curved portion (201F) extends from a first side of the linear portion (201L). The first curved portion (201F) is provided with a curved profile. The second curved portion (201S) extends from a second side of the linear portion (201L). The second curved portion (201S) is provided with a curved profile. The frame unit (202) receives and supports the windshield (201). The windshield (201) is attached to the frame unit (202) by using a sealant or the like. In the present invention, the windshield (201) is provided with a curved profile which provides uninhibited visibility, stretched from a first side of a vehicle (100) to a second side of the vehicle (100). It enables the driver to see not only the road but everything outside of the vehicle (100), giving ample natural light without blinding the occupants of vehicle (100). The curved profile enhances the field of vision of the driver, making it easier to look at the corners. Further, the requirement of using rubber beading for mounting the windshield (201) on to the frame unit (202) is done away with. The present invention uses sealant for mounting the windshield (201) on to the frame unit (202). Therefore, the present invention successfully reduces assembly time and fatigue caused during assembly. The present invention also eliminates issue pertaining to rainwater leakage. Further, the present invention improves the security of the windshield (201) by providing a theft proof configuration. In a preferred embodiment, sealant such as but not limited to Loctite sealant is used for mounting the windshield (201) on to the frame unit (202).
[0038] In one embodiment, the invention may also be used in vehicle (100) where the driver is required to sit near the centre, as the curved profile allows him to increase his field of vision.

The first pillar (202A) is disposed towards a first side of the vehicle (100). A profile of the first pillar (202A) conforms with a profile of a first side of the windshield (201). The first pillar (202A) receives the first side of the windshield (201). The second pillar (202B) is disposed towards a second side of the vehicle (100). A profile of the second pillar (202B) conforms with a profile of a second side of the windshield (201). The second pillar (202B) receives the second side of the windshield (201). The upper member (202U) is disposed towards an upper side of the vehicle (100). A profile of the upper member (202U) conforms with a profile of an upper side of the windshield (201). The upper member (202U) receives the upper side of the windshield (201). The lower member (202L) is disposed towards a lower side of the vehicle (100). A profile of the lower member (202L) conforms with a profile of a lower side of the windshield (201). The lower member (202L) receives a lower side of the windshield (201). In a preferred embodiment, a rear-view mirror is placed on each of the first pillar (202A) and the second pillar (202B). In an open cabin configuration, the driver can directly look into these rear-view mirror. In closed cabin configuration, the driver can look into these rear-view mirror through the windows of the door assembly for the driver cabin.
