Technical Field

[0001] The present subject matter described herein generally relates to a motorcycle and particularly relates to a headlamp housing assembly for a motorcycle. Background

[0002] Typically, a headlamp unit of a motorcycle is housed in a headlamp housing assembly that includes a front housing cover and a rear housing cover attached to each other, and a mounting stay to mount the.headlamp housing assembly to a head pipe of the motorcycle. Further, since the headlamp housing assembly also houses a turn signal lamp unit, a speedometer, a number plate and a visor, the front housing cover and the rear housing cover include a plurality of mounting structures such as metal mounting brackets, mounting bosses and the like at each mounting location. For example, in a known disclosure, the rear housing cover includes individual mounting brackets for receiving the turn signal lamp unit, the front housing cover and the speedometer. The rear housing cover therefore acts as a load carrying member of the headlamp housing assembly and is subject to cyclic stresses at each of the mounting brackets during motorcycle running condition, resulting in rattling of the headlamp unit and breakage of mounting brackets. Therefore, in order to ensure stiffness of the headlamp housing assembly, a plurality of stiffening members are provided in the front housing cover and the rear housing cover, thereby resulting in high part count and increased weight of the headlamp housing assembly. Moreover, providing individual stiffeners also results in increased assembly time for assembling the headlamp housing assembly.

[0003] Besides ensuring that the headlamp housing assembly provides reliable housing for- the headlamp unit, it is also essential to ensure that the headlamp housing assembly is configured to facilitate servicing of bulbs in the headlamp unit. Moreover, as a functional requirement it is essential that a beam of the headlamp unit must be properly oriented. This demands the presence of a provision for adjusting headlamp orientation at any given time.

[0004] In a known art, the front housing cover of the headlamp housing assembly is provided with an adjustment screw at a bottom. portion thereof. However, not only is the access to said adjustment screw difficult but also adjustment of the headlamp unit through the adjustment screw results in formation of uneven gap between the headlamp unit and the front housing cover, thereby affecting overall aesthetics of the motorcycle. Moreover, servicing of the bulbs in the headlamp unit is also not facilitated since the entire headlamp housing assembly has to be dismantled for accessing the bulbs. Reassembly of the complete headlamp housing assembly thereafter is not only cumbersome but also time consuming.

Summary of the Invention

[0005] The present invention has been made in view of the above circumstances.

[0006] It is an object of the present invention to provide a headlamp housing assembly that can reliably accommodate a headlamp unit, a turn signal lamp unit, a visor and a speedometer without involving the use of a plurality of stiffener members.

[0007] It is another object of the present invention to provide a headlamp housing assembly which is light in weight but provides reliable housing for the headlamp unit, the turn signal lamp unit, and the speedometer.

[0008] It is another object of the present invention to provide a headlamp housing assembly that facilitates easy access to the headlamp unit.

[0009] It is yet another object of the present invention to provide a headlamp housing assembly that facilitates easy adjustment of orientation of the headlamp unit.

[0010] It is still another object of the present invention to provide a headlamp housing assembly that has reduced part count.

[0011] It is one more object of the present invention to provide a headlamp housing assembly that involves reduced assembly time.

[0012] The above and other objects are achieved by providing a headlamp housing assembly according to the.present invention. The headlamp housing assembly comprises a front housing cover covering at least a front portion of a headlamp unit, a rear housing cover covering at least a rear portion of the headlamp unit, and a housing stay adapted to detachably attach the front housing cover to the rear housing cover.

[0013] As per an aspect of the present invention, the headlamp housing assembly includes a pair of support stays. Whereas in a first embodiment of the present invention, the pair of support stays is adapted to be mounted to the front housing cover, in a second embodiment of the present invention, the pair of support stays is adapted to be mounted to the rear housing cover. One support stay each of the pair of support stays may be disposed in a left and right side portions of either the front housing cover or the rear housing cover, thereby serving to increase overall stiffness of the headlamp housing assembly. According to an embodiment of the present invention, each support stay of the pair of support stays is an elongated member that includes a stem member, at least two support arms extending from the stem member, and at least one bridge arm extending from a central portion of the stem member. Particularly, while the stem member extends substantially perpendicularly to motorcycle lateral axis direction, said at least one bridge arm protrudes substantially perpendicularly and rearwardly from the stem member. The at least two support arms of the pair of support stays serve to support the pair of support stays on either the front housing cover or the rear housing cover. Further, the at least one bridge arm serves to receive the housing stay. Since the pair of support stays is disposed in the left and right side portion of the front housing cover, uniform stiffness is ensured on both sides of either the front housing cover or the rear housing cover. Thus, without involving the use of a plurality of stiffener members, sufficient support or stiffness is provided to the headlamp housing assembly. Moreover, since part count is reduced overall assembly time also reduces.

[0014] The rear housing cover is provided with mounting provisions for receiving the visor, the speedometer, the front housing cover, the turn signal lamp unit, and the housing stay. According to an embodiment of the present invention, the rear housing cover is detachably attached to the front housing cover through the housing stay. The housing stay as per an embodiment comprises a pair of parallel tubes joined to one another by a horizontal connecting tube. A first end and a second end of the pair of parallel tubes are provided with a circular loop each to receive fork tubes. Further, the housing stay includes an extending arm extending forwardly from said pair of parallel tubes. In a first embodiment, the rear housing cover is secured to the front housing cover through the pair of ' support stays, which in turn is detachably attached to the housing stay by means of an attachment element including a mounting fastener. In another embodiment, the attachment element may include an attachment structure formed integrally in the pair of support stays for attachment with the housing stay. As per an aspect of the present invention, a pivot point is obtained at a point of attachment of said at least one bridge arm with the extending arm of the housing stay. Securing the front housing cover and the rear housing cover together with the housing stay ensures sufficient stiffness for the headlamp housing assembly.

[0015] Furthermore, the housing stay also includes an adjustment bracket extending inclinedly downwards from the horizontal connecting tube. Said adjustment bracket is mounted to the rear housing cover at a bottom portion thereof by means of an adjustment fastener. Left and right side walls of the adjustment bracket provided with an oblong slot each respectively to receive said adjustment fastener. In other words, at least two oblong slots are provided in the adjustment bracket. Removal of the mounting fastener and loosening of the adjustment fastener, allows the front housing cover and the rear housing cover, together with the headlamp unit to swivel about the pivot point in a motorcycle forward direction. As a result, the headlamp unit can be directly accessed without disturbing either a front housing cover sub assembly or a rear housing cover sub assembly, thereby facilitating ease of servicing. Further, orientation of the headlamp unit can also be adjusted by loosening only the adjustment fastener. Movement of the adjustment fastener along the at least two oblong slots causes fine adjustment in orientation of the headlamp unit.

[0016] Thus, the headlamp housing assembly provided in accordance with the present invention not only aids in securing reliable housing without involving the use of a plurality of stiffeners but also facilitates ease of servicing and orientation adjustment of the headlamp unit without involving use of additional parts.

Particularly, while the headlamp unit 25 and the visor 27 are mounted to the front housing cover 30a, the turn signal lamp unit 26 and the speedometer 28 are mounted to the rear housing cover 30b. Further, the rear housing cover 30b is also adapted to receive a number plate (not shown) at a bottom portion thereof.

[0039] FIG.3 and FIG.4 illustrate a mounting scheme provided in the front housing cover 30a for the mounting of the headlamp unit 25 and the visor 27. FIG.3 illustrates a perspective view of the front housing cover 30a, depicting a rear side thereof. Mounting provisions are provided in the front housing cover 30a for receiving the headlamp unit 25 (shown in FIG.2), the visor 27, and the

rear housing cover 30b. For example, in the present embodiment, the visor 27 includes at least a pair of mounting bosses 27a (only one mounting boss of the pair of mounting bosses is visible), for mounting the visor 27 to the front housing cover 30a. Firstly, the visor 27 is mounted to the front housing cover 30a through said at least a pair of mounting bosses 27a provided therein. Thereafter, the visor 27 is fastened to the front housing cover 30a at other mounting locations together with either the rear housing cover 30b or the headlamp unit 25. For example, a pair of side visor mounting lugs 30av is provided in the front housing cover 30a to receive side portions of the visor 27, together with the rear housing cover 30b (shown in FIG.7). Further, a central visor mounting lug 27b is provided in the visor 27 for sandwich attachment with the headlamp mounting lug 25b provided in the front housing cover 30a, and a top mounting bracket 25bb of the headlamp unit 25 (shown in FIG.4). Sandwich mounting of the visor 27 with the front housing cover 30a and the headlamp unit 25 ensures that sufficient stiffness is provided to the visor 27. Moreover, part count in terms of the number of fasteners to be used also reduces, thereby reducing weight and improving overall productivity of manufacturing.

[0040] Additionally, the front housing cover 30a is provided with left and right side mounting lugs 30as and right bottom mounting lugs 30ab to receive the rear housing cover 30b (shown in FIG.7).

-[0041] A recess 25a is provided in the front housing cover.30a, through which the headlamp unit 25 is inserted. A three point mounting is provided for the headlamp unit 25. In the present embodiment, a central headlamp mounting lug 25b is provided in the front housing cover 30a to receive a top mounting bracket 25bb of the headlamp unit 25. A pair of side headlamp mounting bosses 25c is provided to receive corresponding side headlamp mounting brackets 25cc (shown in FIG.4).

[0042] Further as per a first embodiment of the present invention and as shown in FIG.3, a pair of support stays 30ad is disposed in a left and right side portions of the front housing cover 30a. For example, while one support stay of the pair of support stays 30ad is provided in a left side portion, another support stay of the pair of support stays 30ad is provided in a right side portion of the front housing cover 30a. According to the present embodiment, the pair of support stays 30ad is an elongated member that includes a stem member 30ada, at least two support arms 30adb,30adc extending from the stem member 30ada, and at least one bridge arm 30adf extending rearwardly from a central portion of the stem member 30ada. While the stem member 30ada extends substantially perpendicularly to motorcycle lateral axis direction, the at least two support arms 30adb, 30adc, extend along motorcycle lateral axis direction. Further, said at least one bridge arm 30adf protrudes substantially perpendicularly and-rearwardly from the central portion of the stem member 30ada. The pair of support stays 30ad is secured to the front housing cover 30a through the at least two support arms 30adb, 30adc. A pair of upper mounting lugs 30ae and a pair of lower mounting lugs 30af are provided in the front housing cover 30a for receiving said at .least two support arms 30adb,30adc of the pair of support stays 30adb. The pair of support stays 30ad provides stiffness to the front housing cover 30a. Preferably, the pair of support stays 30adb is made of a metal alloy; for example steel. Since, the pair of support stays 30ad almost extend substantially throughout a length of the left and right side portions of the front housing cover 30a, uniform stiffness is provided therein, thereby eliminating the need for other stiffener members. As a result, weight of the front housing cover 30a is also reduced significantly.

[0043] The headlamp unit 25, the visor 27 and the pair of support stays 30ad mounted to the front housing cover 30a form a front housing sub assembly of the headlamp housing assembly 30.

[0044] FIG.5 and FIG.6 illustrate a mounting scheme provided in the rear housing cover 30b for mounting the front housing cover 30a, the speedometer 28 and the housing stay 30c thereto. Particularly, FIG.5 illustrates a perspective view jof a front side of the rear housing cover 30b. The rear housing cover 30b is provided with an upper orifice 30ba to receive the speedometer 28. Further, a pair of speedometer mounting bosses 28a is provided above an upper peripheral edge of the upper orifice 30ba for mounting a pair of speedometer mounting brackets 28aa. An additional central mounting hole 30bc is provided above the upper peripheral edge of the upper orifice 30ba which mates with the central visor mounting lug 27b for fastening the rear housing cover 30b with the visor 27. The rear housing cover 30b further includes left and right side mounting brackets 30bd for sandwich mounting to the front housing cover 30a together with the visor 27 at the pair of side visor mounting lugs 30av provided in the front housing cover 30a. Additionally, a pair of side mounting bosses 30be and a pair of bottom mounting brackets 30bf are provided to be fastened with the left and right side mounting lugs 30as and the left and right bottom mounting lugs 30ab respectively in the front housing cover 30a.

[0045] The turn signal lamp unit 26 is directly mounted to the rear housing cover 30b through a mounting hole 26a provided in said rear housing cover 30b.

[0046] Further, as may be seen in FIG.6, the housing stay 30c is fastened to the rear housing cover 30b. Particularly, the housing stay 30c detachably attaches the rear housing cover 30b to the front housing cover 30a (shown in. FIG.8). The housing stay 30c as per the present embodiment includes a pair of parallel tubes 30ca connected to one another by a. horizontal connecting tube 30cb. An upper end and a lower end of the pair of parallel tubes 30ca is bent to form a circular loop 30caa each to receive fork tubes. Additionally, an extending arm 30cab extends forwardly from the pair of parallel tubes 30ca towards the rear housing cover 30b. The extending arm 30cab is mounted to the front housing cover 30a together with the rear housing cover 30b by means of an attachment element such as a mounting fastener 31. The turn signal lamp unit 26, the speedometer 28, and the housing stay 30c mounted to the rear housing cover 30b forms a rear housing sub assembly of the headlamp housing assembly 30. [0047] . FIG. 7 illustrates mounting of the rear housing sub assembly to the front housing sub assembly. As may be seen the rear housing cover 30b is sandwich mounted to the front housing cover 30a, on either sides thereof, through the extending arm 30cab of the housing stay 30c; the mounting fastener 31 is used for securing the same. The extending arm 30cab is mounted to the front housing cover 30a at said at least one bridge arm 30adf of the pair of support stays 30ad. Further, top side and bottom portions of the rear housing cover 30b are secured to the front housing cover 30a using a pair of fasteners each respectively, Furthermore, a central portion of rear housing cover 30b is secured to the central visor mounting lug 27b in the visor 27. Thus, mounting of the rear housing sub assembly to the front housing sub assembly involves the use of only seven fasteners, thereby facilitating overall assembly of the headlamp housing assembly.

[0048] Particularly as may be seen in FIG.7, said extending arm 30cab is sandwich mounted to said at least one bridge arm 30adf of the pair of support .stays 30ad supported on the front housing cover 30a through the rear housing cover 30b by means of the mounting fastener 31. More particularly, besides the sandwich mounting of the front cover 30a with the rear cover 30b through the at least one bridge arm 30adf of the pair of support stays 30ad and the housing stay 30c, since the front housing cover 30a and the rear housing cover 30b are directly detachably attached at other multiple locations as described above, a pivot point A is thereby obtained at said at least one bridge arm 30adf. Thereby removal of the mounting fastener 31 holding said at least one bridge arm 30a with the extending arm 30cab of the housing stay 30c allows pivotal motion of a remaining portion of the headlamp housing assembly 30 as a single unit other than the housing stay 30c about the pivot point A. For example as may be seen in FIG.8, removal of the mounting fastener 31 and loosening of the adjustment fastener 32 enables swivelling of the front housing cover 30a and the rear housing cover 30b together with the headlamp unit 25, the turn signal lamp unit 26, the visor 27 and the speedometer 28, about the housing stay 30c in a motorcycle forward direction, thus, facilitating direct access to the headlamp unit 25 through a rear side thereof.

[0049] Further as seen in FIG.6, the housing stay 30c includes an adjustment bracket 30cc extending inclinedly downwards from the horizontal connecting tube 30cb. In the present embodiment, the adjustment bracket 30cc includes an upper flat surface 30cca adapted to be inserted into a slot 30bg provided in a bottom portion of the rear housing cover 30b. Further, left and right side walls 30ccb extending downwardly from said flat upper surface 30cca are provided with at least two oblong slots 30ccc. Each oblong slot of the at least two oblong slots 30ccc is adapted to abut with a side mounting hole 30bha provided in a pair of bottom side walls 30bh of the rear housing cover 30b, for mounting the adjustment bracket 30cc to the rear housing cover 30b by means of an adjustment fastener 32. Preferably the adjustment fastener 32 used is a long bolt. Orientation of the headlamp unit 25 can be adjusted by loosening the adjustment fastener 32. Movement of the adjustment fastener 32 along the at least two oblong slots 30ccc ensures'that the front housing cover 30a and the rear housing cover 30b move together with the headlamp unit 25 either towards a left hand side or a right hand side, since both the front housing cover 30a and the rear housing cover b30b are at least partially connected to each other through the housing stay 30c. As a result, relative movement of the front housing cover 30a with respect to the rear housing cover 30b or the relative movement of the headlamp unit 25 with respect to the front housing cover 30a is prevented,' thereby preventing the formation of gaps therebetween.

[0050] Thus, the headlamp unit 25 can be serviced without removal of any component of the headlamp housing assembly 30 and thereby hassles of reassembling the headlamp housing assembly can be avoided.
[0051] FIG.9a illustrates the rear housing sub assembly as per a second embodiment of the present invention. With reference to FIG.9a and FIG.9b, mounting of the rear housing sub assembly to the front housing sub assembly as per the second embodiment of the present invention is described. As per the second embodiment, the rear housing cover 30b is secured to the housing stay 30c through the pair of support stays 30ad. As per the second embodiment, the pair of support stays 30ad includes the stem member 30ada, at least two support arms 30add, 30ade extending from a portion of the stem member 30ada, and at least one bridge arm 30adg extending rearwardly from a portion of the stem member 30ada. While the at least one bridge arm 30adg is fastened with the extending arm 30cab of the housing-stay 30c by means of the mounting fastener 31, one support arm 30add of said at least two support arms 30add, 30ade is fastened to a top mounting boss 30bb provided in said rear housing cover 30b. Further, a second support arm 30ade of said at least two support arms 30add, 30ade is fastened to a side mounting structure 34 provided in the front housing cover 30a (shown in FIG.9b). Thus, as in the case of the first embodiment, pivot point A is obtained at the at least one bridge arm 30adg of the pair of support stays 30ad, where said at least one bridge arm 30adg gets attached to the extending arm 30cab of the housing stay, allowing pivotal motion of the remaining portion of the headlamp housing assembly 30 other than the housing stay 30c. Headlamp orientation is adjustable through the adjustable bracket 30cc of the housing stay 30c as explained in the first embodiment. The pair of mounting stays 30ad aid in providing uniform stiffness in the rear housing cover 30b, thereby aiding in eliminating multiple other stiffener members.

[0052] While the present invention has been shown and described with reference to the foregoing preferred embodiments, it will be apparent to those skilled in the art that changes in form, connection and detail may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
