Japanese Patent No. 4014972

Utility Model Registration No. 2547379

In the headlight device disclosed in Patent Document 1, the housing and the lens are integrated, and aiming adjustment is performed by swinging the reflector inside the housing. It was difficult to apply to small vehicles.
The headlight device disclosed in Patent Document 2 can be reduced in size because the housing can be omitted. However, since the entire lamp body is swung within the body cover, the lens is also swung. For this reason, the opening of the body cover lens facing the lens must be made relatively large. As a result, a relatively large gap is formed. However, since this portion is a conspicuous position on the front surface of the vehicle body, it is desirable to make such a gap as small as possible. It is also desirable to reduce the gap because air resistance increases when air enters through the gap.
Accordingly, an object of the present invention is to provide a motorcycle headlight device that can be aiming without swinging the lens, can be miniaturized, can improve the appearance of the vehicle body, and has low air resistance.

In order to solve the above problems, the invention of claim 1 relating to a motorcycle headlight device includes: a motorcycle headlight device having a reflector provided with a headlight bulb and a lens provided in front of the reflector;
An intermediate connecting member is provided between the lens and the reflector, the lens is attached to a front portion of the intermediate connecting member, and the reflector is connected to a rear portion of the intermediate connecting member so as to be relatively swingable. The intermediate connecting member and the reflector are integrated.

According to a second aspect of the present invention, in the first aspect of the invention, the reflector opens forward, and a gap is formed between the opening edge and the intermediate connecting member so that the gap varies due to the swinging of the reflector. In addition, a seal member that covers this gap and is elastically deformable is provided.

According to a third aspect of the present invention, in the second aspect of the invention, the intermediate connecting member includes a concave portion into which an opening edge of the reflector is fitted, and a gap between the intermediate connecting member and the reflector is formed in the concave portion. In addition, the seal member is mounted in the recess.

According to a fourth aspect of the present invention, in the second aspect of the present invention, a seal member that covers the gap between the intermediate connecting member and the reflector from the outside is provided.

According to a fifth aspect of the present invention, in the first aspect of the invention, a lamp body in which the lens, the intermediate coupling member, and the reflector are integrated is accommodated in a headlight cover, and the intermediate coupling member is placed in the headlight cover. The reflector is supported so as to be swingable with respect to the headlight cover.

According to the first aspect of the present invention, since the reflector is connected to the rear portion of the intermediate connecting member so as to be relatively swingable, the aiming can be adjusted by swinging the reflector. For this reason, the housing which covers the reflector which swings at the time of aiming adjustment is unnecessary, and the headlight can be miniaturized. Further, since the lens can be supported by the intermediate connecting member without swinging, the gap between the lens and the headlight cover opening can be reduced, and the appearance of the front surface of the headlight cover can be improved. Moreover, air resistance can be reduced.

  According to the second aspect of the present invention, by providing the seal member that can be elastically deformed by sealing the gap, the opening edge of the reflector can be swung within the range of the elastic deformation of the seal member. Thereby, aiming adjustment can be performed with the gap sealed.

  According to the invention described in claim 3, by providing the intermediate connecting member with a recess in which the opening edge of the reflector is fitted, and mounting the elastically deformable seal member in the recess, in addition to the seal by the seal member, Thus, the vibration applied to the reflector from the outside can be absorbed by the seal member, and the optical axis can be prevented from shaking due to the vibration.

  According to the invention described in claim 4, since the seal member is provided so as to cover the gap from the outside, it is easy to mount the seal member and the operability in aiming adjustment can be improved.

According to the invention described in claim 5, the lamp unit in which the lens, the intermediate connecting member and the reflector are integrated is accommodated in the headlight cover, the intermediate connecting member is fixed to the headlight cover, and the reflector is attached to the headlight cover. On the other hand, since it is supported so as to be able to swing, the reflector can be supported on the headlight cover without considering the compatibility with the intermediate connecting member.

A headlight mounting hole 18 opened forward is provided at the center of the frontmost portion of the front cover 17, and a lens (described later) of the headlight 20 faces this. The headlight 20 is accommodated in the front cover 17 and supported by the front cover 17. The front cover 17 is an example of a headlight cover in the present application. A stay 21 extends forward from the head pipe 2, and a meter 22 disposed above the headlight 20 is supported. Reference numeral 23 denotes a top bridge, and reference numeral 24 denotes a bottom bridge, which respectively connect the upper portion of the front fork 10 and the head pipe 2.

Next, the motorcycle headlight device according to the first embodiment of the present invention will be described with reference to FIGS. 2 is a front view of a motorcycle headlight device, FIG. 3 is a sectional view taken along line 3-3 in FIG. 2, FIG. 4 is a sectional view taken along line 4-4 in FIG. 2, and FIG. FIG. 6 is an enlarged perspective view of part b in FIG.

As shown in FIG. 2, the headlight 20 includes a lens 30 having an outer portion having a substantially inverted large diameter in a front view shown in the drawing, facing the headlight mounting hole 18 having a slightly larger shape and facing the lens 30. A slight mounting gap 25 is continuously formed around 30 around the opening edge of the headlight mounting hole 18. However, this mounting gap 25 is the minimum necessary for mounting adjustment when the lens 30 is fitted into the headlight mounting hole 18, and is provided to swing the lens 30 by aiming adjustment. Unlike the aiming adjustment gap, it is much smaller than this and almost negligible in appearance.

  As shown in FIG. 3, the headlight 20 includes a lens 30, an intermediate coupling member 31, a bulb 32, and a reflector 33, and has a concave portion that is convex forward and opened rearward across the intermediate coupling member 31. And a reflector 33 having a concave surface that is convex rearward and opened forward is formed from the front and rear to form a sealed space inside these three members, and the bulb 32 is disposed in the sealed space to form a unit. The valve 32 is supported by the reflector 33.

As will be described later, the intermediate connecting member 31 is attached and fixed to the front cover 17, and the lens 30 is fitted and integrated with the intermediate connecting member 31 from the front to the intermediate connecting member 31. Does not move. The lens is fixed to the intermediate connecting member 31 by adhesion or the like.
The reflector 33 is fitted to the intermediate connecting member 31 with an opening edge from the rear, and the reflector 33 can swing with respect to the intermediate connecting member 31 and the front cover 17 at the time of aiming adjustment.

The aiming adjustment is performed by loosening the aiming adjusting bolt 35 for fixing the lower portion of the reflector 33 to the shelf 34 provided at the lower portion of the front cover, and swinging the reflector 33 back and forth around the point P located at the upper portion of the reflector 33. By doing so, the valve 32 supported by the reflector 33 is swung integrally with the reflector 33, and the optical axis L is appropriately changed in the vertical direction between the upper L1 and the lower L2. The angles L1 and L2 are arbitrarily set in advance.
The aiming axis in the aiming adjustment is an axis perpendicular to the paper surface passing through the point P. Details of the aiming adjustment mechanism will be described later.

The lens 30 is made of transparent resin, glass, or the like, and a flange 41 is integrally formed projecting outward in the vicinity of the opening in the peripheral wall 40. A rear portion of the flange 41 forms an opening edge 42. The intermediate connecting member 31 is made of an appropriate resin material, and an outer seal fitting portion 43 is formed on the outer peripheral portion, and an inner seal fitting portion 44 is integrally provided on the inner peripheral side.
The outer seal fitting portion 43 forms a circumferential groove having a substantially U-shaped cross section opened forward, and the outer seal 45 is fitted and held therein. The outer seal 45 is made of an elastic member having a high sealing performance such as rubber, and has a circumferential groove opened forward, and the opening edge portion 42 of the lens 30 is pushed into and fitted in a watertight state. At the fitting limit of the opening edge portion 42, the flange 41 comes into contact with the distal end surface of the outer seal fitting portion 43 to serve as a stopper. The flange 41 of the lens 30 is fixed to the intermediate connecting member 31 by adhesion or the like.

The inner seal fitting portion 44 forms a tapered circumferential groove having a substantially V-shaped cross section that is opened rearward, and the inner seal 46 is fitted and held therein. Like the outer seal 45, the inner seal 46 is made of an elastic member having a good sealing property such as rubber, and has a circumferential groove-like seal groove that is opened rearward. The opening edge 47 of the reflector 33 is pushed into the rear seal 46 from the rear. And fit in a watertight state. The inner seal 46 is fitted and held. The inner seal 46 is relatively thick. For example, the fitting portion of the opening edge 47 is about three times or more the wall thickness of the opening edge 47. Sometimes it is easy for the opening edge 47 to move in the fitted state. The thickness of the inner seal 46 can be freely set in consideration of the elasticity of the material constituting the inner seal 46 and the like within a range in which both the sealing performance and the ease of elastic deformation can be achieved.

As shown in FIG. 4, mounting protrusions 48 are integrally formed to protrude outward from the left and right sides of the intermediate connecting member 31, overlapped with a boss 49 formed on the inner side of the front cover 17, and screw 50 from behind. Thus, the intermediate connecting member 31 is attached to the front cover 17. When the lens 30 and the reflector 33 are fitted to the intermediate connecting member 31, the headlight 20 becomes a lamp body in which the lens 30 and the reflector 33 are integrated as a unit via the intermediate connecting member 31, and the inner side of the front cover 17. Thus, the lens 30 faces the headlight mounting hole 18. The boss 49 is provided at the periphery of the headlight mounting hole 18 and inside the portion facing the left and right side portions of the lens 30.

3 and 4, the intermediate connecting member 31 continuously integrates the outer peripheral wall 52 and the intermediate peripheral wall 53 constituting the outer seal fitting portion 43, and the inner peripheral wall 54 constituting the inner seal fitting portion 44 together with the intermediate peripheral wall 53. Prepare for. The outer peripheral wall 52 and the intermediate peripheral wall 53 form a tapered wall that inclines outward toward the front. Moreover, the intermediate | middle peripheral wall 53 and the inner peripheral wall 54 make the taper wall which inclines in the outward opening shape toward back. The inner peripheral wall 54 is the widest in the front-rear direction and has a cylindrical shape that opens in the front-rear direction. This inner space forms a passage for light emitted from the bulb 32. The front end surface of the intermediate coupling member 31 forms a rear inclined surface extending obliquely upward and rearward in a side view in the illustrated state.

As shown in FIG. 6, which is an enlarged cross-section of the B part in FIG. 3, the outer seal fitting part 43 forms a circumferential groove whose front opening is widened forward by a tapered outer peripheral wall 52 and an intermediate peripheral wall 53. When the outer seal 45 is fitted and the opening edge 42 of the lens 30 is pushed into the seal groove 45a provided in the outer seal 45 from the front, the tighter the push, the tighter the outer seal 45 is adhered to the opening edge 42. Thus, the sealing property is further improved. In this state, the lens 30 and the intermediate peripheral wall 53 are fixed with an adhesive or the like.

The inner seal fitting portion 44 has a tapered inner peripheral wall 54 and an intermediate peripheral wall 53 to form a circumferential groove having an opening that extends rearward, so that an inner seal 46 having a tapered cross section is fitted therein. When the opening edge portion 47 of the reflector is fitted into the sealing groove 46a that forms the circumferential groove formed in the seal 46 and pushed from the rear, the inner seal 46 adheres more firmly to the opening edge portion 47 as the force is pushed more strongly. Increases nature. Further, the inner seal 46 is firmly attached to the inner peripheral wall 54 and the intermediate peripheral wall 53 by taper bonding, and the sealing performance is also improved in this respect.

Moreover, the inner seal 46 elastically supports the opening edge 47 of the reflector, and even if the opening edge 47 moves within the inner seal fitting portion 44 during aiming adjustment, the adhesion of the inner seal 46 to the opening edge 47 is improved. In addition, since the close contact between the inner peripheral wall 54 and the intermediate peripheral wall 53 and the inner seal fitting portion 44 is high, it is possible to maintain high sealing performance against such movement. In addition, if the lightening groove 46b is provided near the seal groove 46a, the opening edge 47 of the reflector can be moved more easily. Further, if a plurality of seal lips 46 c are provided on the seal surface of the inner seal fitting portion 44 that contacts the inner peripheral wall 54 and the intermediate peripheral wall 53, higher sealing performance can be obtained.

As shown in FIG. 3 and FIG. 5 which is an enlarged perspective view of the portion A in the figure, the support arm portion 53 forms a substantially strip plate shape from the bottom on the upper side of the outer seal fitting portion 43 and is substantially horizontal rearward. A horizontally elongated square hole 54 is formed at the tip. On the other hand, a substantially strip-shaped fulcrum arm 55 is integrally formed so as to project upward from the upper part on the outer surface side of the reflector 33, and the tip of the fulcrum arm 55 penetrates the square hole 54 and the tip projects upward. . The square hole 54 has a size for loosely fitting the fulcrum arm 55, and the fulcrum arm 55 can swing within the square hole 54.

The fulcrum arm 55 is provided with a vertically long square hole 56 that intersects the square hole 54 and extends to the upper and lower sides of the support arm portion 53, and has a substantially U-shape straddling the tip of the support arm portion 53 in the vertical direction. An elastic clip 57 made of a leaf spring is fitted. The fulcrum arm 55 is prevented from being detached from the support arm portion 53 by the elastic clip 57 and is supported by the elasticity of the elastic clip 57 so as to be swingable around the point P with respect to the support arm portion 53. Further, since the support arm portion 53 and the fulcrum arm 55 are loosely fitted to each other and are swingably connected only by being prevented by the elastic clip 57, the connection between the support arm portion 53 and the fulcrum arm 55 is facilitated.

As shown in FIG. 3, a swing arm 58 is integrally formed so as to protrude downward at the lower portion on the outer surface side of the reflector 33. The lower end of the swing arm 58 extends to the upper surface of the shelf 34 provided at the lower portion of the front cover 17, and the nut 36 is integrated with the lower end thereof. An elongated hole 37 is formed in the shelf 34 in which the integral swing arm 58 slides in the front-rear direction by the swing of the reflector 33, and the aiming adjustment bolt 35 is inserted into the elongated hole 37 from below to swing. If the nut 36 integrated with the lower end of the arm 58 is fastened and tightened firmly, the swinging arm 58 is fixed to the shelf 34 and cannot be moved. The axis L can be made constant. If the aiming adjusting bolt 35 is loosened, the inside of the elongated hole 37 can be moved in the front-rear direction. Therefore, if the aiming adjusting bolt 35 is moved back and forth along the elongated hole 37, the reflector 33 is swung around the point P. The optical axis L can be adjusted by moving.

  According to the motorcycle headlight device according to the first embodiment configured as described above, when adjusting the aiming, as shown in FIG. If the reflector 33 is swung around the point P by moving it back and forth along the, the aiming adjustment can be performed because the valve 32 swings integrally.

At this time, when the opening edge portion 47 of the reflector 33 is fitted to the intermediate connecting member 31 via the inner seal 46 so as to be swingable, the inner seal 46 has high sealing performance and elastic deformation ease. Since the reflector 33 can be swung while the sealing performance is maintained, the opening edge 47 of the reflector 33 can be fitted into the intermediate connecting member 31, and a housing that covers the periphery of the reflector as in the prior art becomes unnecessary. As a result, the headlight can be reduced in size. Further, since the vibration applied from the front cover 17 side to the reflector 33 side can be absorbed by the elasticity of the inner seal 46, the optical axis shake due to the vibration can be suppressed.
In addition, since the lens 30 is fixed, it is not necessary to provide a large gap for aiming adjustment around the lens 30, and the minimum gap 25 can be provided, so that the appearance can be improved.

Next, a description will be given of a motorcycle headlight device according to a second embodiment of the present invention with reference to FIGS.
7 is a cross-sectional view of the same part as in FIG. 3, FIG. 8 is a cross-sectional view of the same part as in FIG. 4, and FIG. In addition, the same code | symbol is attached | subjected about the same component as the component mentioned above, and the description is abbreviate | omitted. The headlight 120 of this example shares the lens 30 and the bulb 32 with the previous embodiment. There are some changes in the seal structure in the intermediate connecting member, the reflector, and the connecting portion thereof.

The intermediate coupling member 131 has an outer seal fitting portion 143 formed on the outer peripheral portion, and includes an outer peripheral wall 152, an intermediate peripheral wall 153, and an inner peripheral wall 154 that constitute the outer seal fitting portion 143 in an integrated manner. The outer seal fitting portion 143 has the same structure as that of the previous embodiment, the outer seal 145 is fitted, and the lens 30 is further fitted. The flange 41 of the lens 30 configured similarly to the previous embodiment is fixed to the outer peripheral wall 152 of the intermediate connecting member 131 by adhesion or the like.
A first peripheral wall 160 projecting outward is integrally formed at the bottom of the outer seal fitting portion 143. A support arm portion 153 similar to that in the previous embodiment is provided on the inner side, and is connected to a fulcrum arm 155 formed on the reflector 133 by an elastic clip 57 as in the previous embodiment.

A second peripheral wall 170 that protrudes rearward is integrally formed on the back surface of the reflector 133. The second peripheral wall 170 is provided on the inner side (closer to the valve 32) than the support arm portion 153, and the fulcrum arm 155 is spaced from the outer peripheral portion of the reflector 133 to the outer side of the second peripheral wall 170 so as to be on the outer side of the second peripheral wall 170. Projecting rearward so as to partially overlap, bent at a position overlapping the second peripheral wall 170 and extended upward.
The first peripheral wall 160 and the second peripheral wall 170 overlap with each other in parallel with an interval, and are sealed with an elastic cap 180 covered from behind so as to cover the space therebetween.

As is apparent from FIG. 9, the elastic cap 180 has a ring shape made of an elastic member having a high elasticity such as rubber and having a sealing property. A ring portion having a predetermined width of about the distance between the first peripheral wall 160 and the second peripheral wall 170 has a substantially U-shaped cross section, and includes an outer peripheral portion 181, an inner peripheral portion 182, and a bottom surface portion 183, and is surrounded by these. The part forms a circumferential groove that opens forward. The outer peripheral portion 181 is overlapped with the outer surface of the first peripheral wall 160 and closely adhered to the outer surface, and the inner peripheral portion 182 is overlapped with the outer periphery of the second peripheral wall 170 and closely adhered to the outer surface, whereby the first peripheral wall 160 and the second peripheral wall 170 are Seal the gap. In addition, you may adhere | attach between the outer peripheral part 181 and the 1st surrounding wall 160, and between the inner peripheral part 182 and the 2nd surrounding wall 170, respectively.

Further, the front end 154a of the inner peripheral wall 154 provided in the same manner as the previous embodiment of the intermediate connecting member 131 and the front end 147a of the opening edge portion 147 of the reflector 133 are opposed to each other, and a slight gap is provided between both ends. Thus, the reflector 133 can be swung during aiming adjustment.
As shown in FIG. 7, a swing arm 158 is integrally formed to project downward from the lower portion of the reflector 133, but is bent in a substantially U shape so as to surround the bottom surface portion 183 of the elastic cap 180 from the outside. The lower end portion is fixed to the shelf portion 34 with a nut 36 and an aiming adjusting bolt 35 which are integrated as in the previous embodiment. Thereby, the aiming adjustment structure similar to the previous embodiment is formed.

According to the motorcycle headlight device according to the second embodiment configured as described above,
When the reflector 133 swings during aiming adjustment, the elastic cap 180 enables the reflector 133 to swing while being elastically deformed. At the same time, the gap between the intermediate connecting member 131 and the reflector 133 is reliably sealed. Therefore, in this embodiment, the housing that covers the outside of the reflector 133 can be omitted, and the appearance can be improved by fixing the lens 30.

In addition, a lamp body in which the lens 30, the intermediate connecting member 131 and the reflector 133 are connected and integrated is accommodated inside the front cover 17, the intermediate connecting member 31 is fixed to the front cover 17, and the reflector 133 is shaken with respect to the front cover 17. Since it is supported movably, the reflector 133 can be supported on the front cover 17 without considering the alignment with the intermediate connecting member 131.

Furthermore, since the elastic cap 180 has a structure that covers the first peripheral wall 160 and the second peripheral wall 170, the degree of freedom of attachment and shape is increased, and attachment work is facilitated. In addition, a thin film like a diaphragm can be formed, and in this case, almost no force required for elastic deformation is required, so that the swing of the reflector 133 becomes light and the aiming adjustment is facilitated. Can do.

FIG. 10 shows a modification of the reflector. A bulb 32 is provided at the center of the concave curved reflector 233, and a shade 200 formed in a concave curved surface centered on the optical axis L is disposed in front of the bulb 32. The shade 200 is smaller than the reflector 233 and is disposed so as to protrude forward inward from a line D connecting the center of the bulb 32 and the tip 233a of the reflector 233, with the concave curved surface facing the bulb 32 and the reflector 233. Further, as shown in the enlarged portion in the figure, a reflective surface 201 is formed on the concave curved surface by plating or coating so as to be a reflecting mirror.

As a result, the light traveling from the bulb 32 to the shade 200 is reflected from the reflecting surface 201 formed on the concave curved surface of the shade 200, travels toward the reflector 233, and is re-reflected further forward from the reflecting surface of the reflector 233. The light passing outside the shade 200 is irradiated forward without being blocked by the shade 200. As a result, compared with a conventional shade that is painted black and does not form a reflective surface, waste of light flux by the shade 200 is avoided, so that the reflection efficiency can be improved and the amount of light can be increased. Since the amount of light entering the front of 200 increases, the shade shadow can be reduced.
