FIELD OF THE INVENTION
The present invention proposes a headlamp assembly which includes a cover for preventing water entry through the headlamp cut-out in three-wheeled vehicles.
BACKGROUND
In vehicles, water enters through the headlamp cut-out in the front cowl. Especially in case of three-wheeled vehicle, the driver has difficulty due to the entry of water into the driver cabin through the headlamp area during rainy days and water wash. Moreover, the entry of water leads to corrosion in the cowl assembly and also affecting the floor of the driver cabin, resulting in repairs that may involve replacement of chassis itself. To avoid the water entry, the bezel which is a plastic part covered with a headlamp has to be made from soft material with more thickness, for example, Polyurethane, that results in increased cost, which is not desired.
SUMMARY OF THE INVENTION
In this invention, the surface at the headlamp mounting area is an undulated surface, because of the variation in design.
A funnel-like part needs to be designed, to address the water entry issue with low-cost impact and without affecting the style of the vehicle. The new part will act like water guide, in such a way that the water will be guided to outside of the vehicle.
The cover assembly for a three-wheeled vehicle that provides driver comfort by eliminating entry of water through headlamp opening. The cover assembly comprising, a bezel, a cowl, a headlamp cut-out, a reinforcement cowl, headlamp assembly, bracket headlamp mounting, cowl assembly, a headlamp cover, and a rubber boot. The headlamp cover is welded to the cowl assembly. The rubber boot is assembled in the cowl assembly on the headlamp cover. The headlamp is assembled on chassis. The rubber boot is like a funnel and acts as a water guide such that the water is guided outside the vehicle. The design results in an undulated surface at headlamp mounting area. The water is directed through the

rubber boot and sent outside the cowl instead of entering the driver compartment. The cover leads to less design cost and low maintenance cost and applies to three-wheeled vehicles.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
In the cover assembly that prevents water entry, a headlamp cover is welded to a cowl assembly of the chassis. A rubber boot is assembled in the cowl assembly on the headlamp cover. The headlamp is assembled on the chassis.
Figure 1 shows the outside view of a cowl assembly 9 in the vehicle. The direction of water entry into the vehicle’s headlamp or the driver’s compartment has been indicated by the arrows A, during the rainy days or water wash. The water enters the vehicle through a gap in-between a bezel 2 and cowl 3, and through a headlamp 1 and bezel 2 of the three-wheeled vehicles.
Figure 2 shows the inside view of the cowl assembly 9 in the vehicle. The direction of the water entry into the driver’s compartment has been indicated by arrows 6, during the rainy days or water wash of the vehicle. The water enters the vehicle through the headlamp cut-out 4 of reinforcement cowl 5, and the gap in-between reinforcement cowl 5 and cowl 3 of the three-wheeled vehicle.

Figure 3 shows the section view of the existing cowl assembly Y-Y section with a bezel 2, a reinforcement cowl 5, a headlamp mounting bracket 8, and a headlamp assembly 7, in the headlamp area. The existing cowl assembly has no proper technique for the water entry prevention. Hence, the water enters into the driver’s compartment through the gaps present on the cowl, particularly in the headlamp assembly. The pathway of water entry into the driver compartment is indicated by arrows B.
The design according to the present subject matter provides driver comfort by eliminating entry of water through headlamp opening and the design includes a rubber boot. The rubber boot is assembled in the cowl assembly on the headlamp cover. The shape of the rubber boot is like a funnel and acts as a water guide such that the water is directed outside the vehicle. Also, the design results in an undulated surface at the headlamp mounting area ensuring draining of the water. The water is directed through the rubber boot and sent outside the cowl instead of entering the driver compartment.
Figure 4 shows the exploded view of the parts getting assembled to the cowl 3 in the modified design. The modified design includes a funnel-like water guide part, a cover for water entry prevention into the three-wheeled vehicles through the headlamp called a boot 11. The cut-out headlamp cover 10 is welded to the cowl assembly 9 of the chassis. The boot 11, can be made of rubber or the like, is assembled in the cowl assembly 9 on the headlamp cover 10. The headlamp cover 10 is fixedly attached to the cowl assembly 9 through welding including one or more weld nuts. In one embodiment, at least a portion of said headlamp cover 10 includes at least one mounting hole 10a adapted to receive at least one mounting member therein for detachably securing said rubber boot 11 and said headlamp assembly 7 to said headlamp cover 10. As per one embodiment, said at least one mounting member includes a fastener. Hence, said headlamp assembly 7 and said rubber boot 11 is detachably attached to chassis through said headlamp cover 10.
Figure 5 shows the section view A-A section of the modified cowl assembly with the bezel 2, headlamp assembly 7, headlamp cover 10, rubber boot 11 and

reinforcement cowl 5 in the headlamp area. In this design, the water is guided C through the rubber boot 11 on the headlamp area and sent outside the cowl 3. Thus, prevents water entry into the driver compartment of the three-wheeled vehicle.
The rubber boot 11 act as a water guide, in such a way that the water will be channeled outside of the vehicle. The design is applied to three-wheeled vehicles at less cost and also minimizes the vehicle maintenance expenses.
