Headlamp Housing for Motorcycle

Field of the Invention:

The present invention relates to a "Headlamp Housing for Motorcycle". In particular this invention relates to headlamp assembly housing structure for motorcycle.

Background of the Invention:

In a typical motorcycle, headlamp is housed in head lamp housing assembly which comprises of a front cowl (herein after referred to as head lamp housing front or HLF) and headlamp housing rear (HLR). The HLF is also provided with a visor. The HLR is located in between the back side of the HLF and handle bar. The HLF and HLR are connected through brackets which is a part of sub frame attached to the front suspension of the vehicle. Generally, the front edge of the HLR comes in contact with the visor and the rear surface comes in contact with the handle bar bracket plastic cover. During running condition these contacts leads to vibration and rattling sound. In order to avoid the above problem quite a number of rubber pads were provided which were manually glued to the headlamp housing rear. And since it is manually fixed no accuracy as to the location is guaranteed and in long run the rubber pads are also dislocated. The other disadvantage associated with the rubber pads is that it leads to an uneven gap formation between the components.

Typically, the HLR accommodates the speedometer housing or like components, is made, up plastic. The rubber grommets which are generally provided between the HLF and HLR is visible from outside and along with that because of gap between these components, the light from the headlamp leaks from this gap, thereby reducing the light efficiency required for illuminating the roads. Current arrangement of HLF and HLR leads to more flexing of HLR and in addition to that a lot of area available in HLR goes unutilized.

Therefore, there is a need for providing a improved headlamp housing assembly structure to overcome the above stated problems.

Summary of the Invention:

The present invention has been achieved in an effort to bring out a solution, which overcomes the above mentioned problems.

It is therefore an object of the present invention to provide a headlamp housing assembly which isolated vibration to a greater extent.

Another object of the present invention is to provide a headlamp housing assembly which does not allow the leakage of light between HLF and HLR.

Yet another object of the present invention is to provide a headlamp housing assembly, which is capable of holding articles in HLR.

Description of the invention:

The present invention relates to a headlamp housing assembly for a motorcycle.

With reference to figure 1 a motorcycle comprises of a frame (101), front fork (102) attached to a pivot tube (201) of the vehicle frame, a front wheel (103) attached to these front forks (102), a handle bar (104) connected to the front forks (102), a fuel tank (105) attached so as to straddle an upper part of the vehicle frame, a seat (106) attached to the upper rear portion of the vehicle frame, an engine unit (107) attached to the lower front section of the vehicle frame, a swing arm (108) attached to a lower rear section of the vehicle frame, suspended by a rear shock absorber (not shown) from the vehicle frame and a rear wheel attached to a rear end of swing arm (108). The intake system of the engine comprises of a fuel air metering device such as a carburettor (109), intake duct and an air cleaner. The exhaust system of the engine comprises of exhaust pipe and a muffler.

The motorcycle is provided with a front fender (110) for covering an upper part of the front wheel (103), and a rear fender (111) for covering an upper part of the rear wheel (112). The drive from the engine (107) is transmitted from the engine to the driven wheel sprocket mounted on the rear wheel hub mounted on the rear wheel assembly.

Referring to figure 2, the upper portion of the front fork (102) for supporting front wheel is connected to a head pipe through a bottom bridge (201) and a top bridge (202). A front cowl or fairing (203, which is also referred to as HLF hereinafter) is mounted onto a support structure, which goes into the fork inner of front fork (102). A headlight (204) goes into the cavity of the HLF (203). Two winkers (301, 302) are mounted onto to two brackets extended from the tube outer of the support structure through the relief (401) provided in the side of HLR (402) ( as shown in figure 3 and 4). The support structure is assembled onto the front fork inner of the front fork (102). A handle bar (104) is mounted through a handle shaft to an upper extending portion of the front fork (102). A fuel tank (105) is provided between the handle bar (104) and the seat (106).

The HLF (203) is provided with a visor (205). The HLR (402) is located in between the back side of the front cowl (or HLF) (203) and handle bar (104).

The HLR (402) according to one embodiment of the present invention unites the HLF (203) (which covers at least the front portion of the motorcycle) and a plurality of winkers and instrument cluster housing. The HLR (402) is provided with a relief (403) on its upper side or top section. This relief (403) is of a shape which exactly matches the profile of the instrument cluster housing.

As shown in figure 5, the HLR (402) is fastened to the HLF (203) by screws and the rear surface has opening portion to accommodate the holder for the lamps, wiring circuits, etc. The visor (205) from the HLF (402) comes in contact with the front edge of the HLR (402) and the side of the HLR (402) where it is fastened to front cowl by a bracket, also comes in to contact.

Referring to figure 5 and 6, a flap is provided on the front edge of the HLR (402), approximately in the midway of HLR (402). The said flap (404) is further provided with at least one rubber grommet (501, 502). The rubber grommets (501, 502) are placed is such a fashion that it also avoids the visor (205) contact with the HLR (402). The said flap (404) with the rubber grommet (501, 502) fits exactly to the outer edge profile of HLF (203).

The said HLR (203) after accommodating the instrument cluster still has area between the HLR (402) front edge and instrument cluster. The said space is designed with a depression (405) such that it can be used to hold any small article in HLR.

The said HLF (203) is provided with an extended screen (601) where the rubber grommet (501, 502) is attached with the housing headlamp front (203). The said screen (601) helps in avoiding the light leakage thereby increasing the headlamp efficiency.

The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the claims.
