Description

[Detailed description of the invention] [Field of industrial application] The present invention can easily determine whether the irradiation angle of an automobile headlamp is in the correct position, and if it is not in the correct position, the irradiation angle of the headlamp can be This invention relates to a headlamp that can be easily adjusted to the normal position.

[Prior Art] A headlamp is equipped with an aiming mechanism that can tilt around a predetermined horizontal axis and a vertical axis.
The irradiation direction of the headlamp, so-called the irradiation angle of the headlamp, is adjusted (hereinafter referred to as aiming adjustment) so that it is within a predetermined range.
The aiming mechanism of this headlamp actually turns on the headlamp in a dark room.
The light is irradiated onto a screen that is a certain distance away from the headlamp, and the irradiation spot on the screen is adjusted so that it is at a predetermined position.

[Problem that the invention attempts to solve]

However, the above-mentioned conventional aiming adjustment requires a large dark room, a large amount of equipment such as a screen, and so on. Another problem was that the aiming adjustment had to be made while looking at the screen so that the headlamp's irradiation spot was at the predetermined position, making the adjustment process time-consuming.

In addition, headlamps used in the United States have three location bosses that serve as measurement reference surfaces protruding from the front lens, and a measuring device commonly called an aimer is placed in contact with these location bosses. However, it is designed to measure whether the headlamp is tilted with respect to the horizontal plane. That is,
When the car is in a horizontal position, the front end face of the location boss is formed to be a vertical plane.If the aimer is set using the front end face of the location boss as the contact reference surface, the inclination of the headlamp with respect to the horizontal plane can be adjusted. Quantities can now be measured. And the value measured by this aimer (amount of inclination)
is required to be within a predetermined range. Therefore, a location boss must be formed in a headlamp for the United States, and there is also the hassle of having to manufacture a headlamp for the United States independently in addition to the headlamp for Japan and Europe.

The present invention was developed in view of the problems of the prior art described above, and its purpose is to create a simple structure that does not require any darkroom, large-scale equipment such as screens or aimers, and to eliminate irregularities in the irradiation angle of the headlamp. To provide a headlamp for an automobile that allows anyone to easily check whether the illumination angle is correct, allows anyone to easily adjust the illumination angle of the headlamp, and is especially convenient for reading the inclination of the illumination angle in the vertical direction. .

[Means to solve the problem]

Automotive headlamps include a movable reflector type in which a reflector separate from the lamp body is provided within the lamp body so that it can tilt relative to the lamp body, and a movable reflector type in which a light reflecting surface is integrally formed on the inner peripheral surface of the lamp body. There are two types of unit movable types in which the lamp body is provided so as to be tiltable with respect to the vehicle body, and the measures taken in each case will be explained below.

First, in the case of a headlamp with a movable reflector, the reflector is supported so as to be tiltable vertically and horizontally relative to the lamp body, and the reflector is equipped with a tilt measuring device that measures the vertical tilt of the reflector. The headlamp for an automobile is equipped with a casing having a viewing window attached to the reflector and displaying a reference point or a scale, and a horizontal axis that is a pivot shaft for tilting the reflector in the vertical direction within the casing. a pendulum body supported on a support shaft parallel to the shaft and swinging so as to always maintain a constant vertical state with respect to vertical tilting of the reflector; A rotating display body in which a display part on which a scale or a reference point is displayed for indicating the amount of inclination of the reflector is displayed in cooperation with a display on the side of the peephole, which is shown through the peephole; It is constructed by a gear mechanism that transmits information to the display body.

On the other hand, when the headlamp is a movable unit type, the lamp body with a light reflecting surface formed on the inner peripheral surface is supported so as to be tiltable vertically and horizontally relative to the lamp mounting surface on the vehicle body side. The lamp body is equipped with an inclination measuring device for measuring the vertical inclination of the lamp body. A casing with a window, and a support shaft within the casing that is parallel to the horizontal axis that is the vertical tilting support shaft of the lamp body, so that it always maintains a constant vertical state even when the lamp body tilts in the vertical direction. an oscillating pendulum, and a scale or reference point display supported within the casing by a support shaft parallel to the horizontal axis, which cooperates with the display on the viewing window side to indicate the amount of inclination of the lamp body. The device is constructed of a rotary display body whose portion is seen through a peephole, and a gear mechanism that magnifies the amount of rotation of the pendulum body and transmits it to the rotary display body.

[Effect]

By tilting the reflector (lamp body for movable units) vertically and horizontally, the illumination angle of the headlamp can be adjusted. The vertical inclination of the reflector (lamp body for movable unit types) can be read with a tilt measuring device; however, with this inclination measuring device, the pendulum rotates so that it is always in a vertical state, and the amount of rotation is magnified by a gear mechanism to move the display section of the rotating display body. Therefore, the inclination of the reflector (or the lamp body in the case of a movable unit type) appears as a large deviation between the reference point or scale display on the viewing window and the scale or reference point display on the display section of the rotary display.

Further, reference numeral 7 is a clip for mechanically fastening the front lens 6 and the lamp body 2.

In FIGS. 1 to 3 and 5, reference numeral 5
0 is a first inclination measuring device that is provided at a horizontal plane position including the horizontal axis Lx and measures the inclination of the reflector 4 in the left-right direction. Inside the lamp body 2,
A cylindrical protrusion 2b integrally formed with the lamp body protrudes toward the reflector 4 and extends over a recess 4a formed in the left corner region of the upper wall of the reflector 4. A tilt measuring device 50 is attached to this lamp body protrusion 2b and is arranged parallel to the optical axis l. The inclination measuring device 50 includes a cylindrical support member 52, a rod member 54 inserted into the support member 52, and a compression coil spring 56 located within the support member 52 and urging the rod member 54 forward. .

A circumferential reference line 52a is attached to the outer periphery of the tip of the support member 52, while a linear scale 62 is attached to the small diameter portion 61 of the rod in the axial direction. Accordingly, the rod member 54 also slides back and forth in the axial direction, and the scale at the reference line 52a position changes. Further, the rod small-diameter contact surface 4c ₁ of the vertical wall 4c is a curved surface with a radius R centered on the horizontal axis Lx, as shown in FIG.
The scale of the first inclination measuring device 50 does not change due to the vertical tilting of the reflector. When the horizontal inclination of the reflector 4 is appropriate, the zero point 62a of the scale 62 is set to coincide with the reference line 52a position, and the scale at the reference line 52a position indicates the amount of horizontal inclination of the reflector 4. It has come to be expressed.

And the reference line 52a which is this scale reading point

are formed at regular intervals so that light leakage from the side surface of the front lens is not noticeable.
is a non-step surface, and the amount of inclination can be read through this non-step surface.

In Fig. 1 to Fig. 3 and Fig. 6 to Fig. 10,
Reference numeral 70 is a second inclination measuring device for measuring the vertical inclination of the reflector 4;
A recess 4b is formed in the right corner region of the upper wall of the recess 4b, into which a second inclination measuring device 70 is fixedly attached by suitable fixing means such as adhesive or screw fastening.

Reference numeral 71 denotes a rectangular measuring instrument casing that is attached and fixed to the reflector 4. A viewing window 72 is formed on the upper wall of the casing, and a cover 73 made of transparent resin is attached to the viewing window 72. A reference point 72a is attached to the edge. A pendulum body 80 is assembled at a substantially central position in the vertical direction within the casing 71 so as to be rotatable around an axis Lx ₁ parallel to the horizontal axis Lx, which is the center axis of the swinging (tilting) of the reflector 4 . The pendulum body 80 is configured such that a shaft portion 81 of a semi-disc member 82 is pivotally supported by opposing side walls 71a and 71b, and a weight member 83 is assembled to the semi-disk member 82, so that the weight member 83 is always at a lower position. It is in a drooping state. Furthermore, a rotary display body 90 that is rotatable around an axis Lx ₂ parallel to the horizontal axis Lx is assembled above the pendulum body 80 in the casing. In this rotary display body 90, a shaft portion 91 of a disc member 92 is pivotally supported by opposing side walls 71a and 71b, and a scale plate 94 is fixed to the outer peripheral edge of the disc member 92. A scale 96 is displayed on the scale plate 94, and cooperates with a reference point 72a attached to the viewing window 72 to indicate the amount of inclination of the reflector 4. Note that the reference numeral 96a indicates the zero point position of the scale.

Moreover, between the pendulum body 80 and the rotating display body 90,
A gear mechanism 100 is provided that magnifies the amount of rotation of the pendulum body 80 and transmits it to the rotating display body 90. Reference numeral 102 denotes a fan-shaped swinging member having a shaft portion 101 pivotally supported by the side walls 71a and 71b, and is assembled so as to be rotatable around an axis _Lx3 parallel to the horizontal axis Lx. A gear 104 is formed on the shaft portion 101 and is located below the shaft portion 81 of the pendulum body. This gear 104 is the semi-disc member 8 of the pendulum body 80.
It meshes with the tooth part 84 formed in 2,
Therefore, the fan-shaped swinging member 10 is restrained by the pendulum body 80 that always maintains a constant hanging state in the direction of gravity.
2 is held in a state in which the arcuate portion 102a is erected upward. The fan-shaped swinging member 102 has a frame shape with a punched center region, and the arcuate portion 10
A tooth portion 106 is formed inside the arcuate frame forming 2a. This tooth portion 106 is the rotary display body 9
This meshes with a gear 96 formed on the shaft portion 91 of the fan-shaped swing member 102.
The rotary display body 90 rotates in conjunction with the rocking around _Lx3 . That is, the tooth portion 84 formed on the semi-disc member 82 of the pendulum body 80, the gear 104 of the fan-shaped swing member shaft portion 101, the tooth portion 106 formed on the arcuate frame of the fan-shaped swing member 102, and Gear 9 formed on rotation display body shaft portion 91
6 constitutes a gear mechanism 100 that magnifies and transmits the amount of rotation of the pendulum body 80 to the rotating display body 90.

Next, the operation of this inclination measuring device 70 will be explained.

Since the pendulum body 80 always tries to maintain a vertical state, when the reflector 4 is tilted, the pendulum body 80 can be said to swing relative to the reflector 4 (and the casing 71) by an amount equivalent to the tilt amount of the reflector 4. The swinging of this pendulum body 80 causes the gear mechanism 1
00 to the scale plate 94 of the rotating display body 90
The angle of inclination of the reflector 4 can be read by reading the scale 96 of the scale plate 94 at the reference point 72a position.

Furthermore, due to the swinging of the pendulum body 80 around the axis Lx ₁ , the fan-shaped swinging member 102 swings around the axis Lx ₃ .
At this time, the amount of swing of the toothed portion 106 is increased by an amount equivalent to the radius ratio of the gear 104 and the toothed portion 106. Furthermore, due to the meshing between the tooth portion 106 and the gear 96, the gear 9
The amount of oscillation is further expanded by the radius ratio of the disc member 92 and the radius ratio of the disc member 92. Therefore, the amount of movement of the scale plate 94 is the amount of oscillation of the pendulum 80, that is, the amount of movement of the reflector 4.
The amount of inclination of the reflector 4 can be read with high accuracy.

Then, when the vertical inclination of the reflector 4, that is, the irradiation angle of the headlamp is at the appropriate vertical position, the zero point position 96a of the scale plate 94 of the inclination measuring device 70 is set to coincide with the reference point 72a on the casing side. ing. Note that the area 6b corresponding to the inclination measuring device 70 on the upper side wall of the front lens
6b is also a non-step surface, and the amount of inclination can be read from above the side edge of the front lens via this non-step surface 6b.

Next, the procedure for adjusting the inclination measuring device when the headlamp is assembled to the vehicle body and the procedure for adjusting the irradiation angle of the headlamp thereafter will be explained.

As for a single headlamp, when the zero point position 62a of the scale of the rod member 54 of the first inclination measuring device 50 coincides with the position of the reference line 52a, the light distribution characteristics in the left and right direction of the headlamp are at the appropriate position, and the second inclination measurement is performed. Zero point position 9 of scale plate 94 of instrument 70
6a coincides with the casing-side reference point 72a, the vertical light distribution characteristics of the headlamp are set to be at an appropriate position.

and these first and second inclinometers 5
When a headlamp with a built-in 0.70 meter is assembled to a vehicle body, the scale display of each inclination measuring device will not be at the correct position due to various errors. Therefore, it is necessary to adjust the scales of the first and second inclination measuring devices to an appropriate state.

As this scale adjustment method, the first inclination measuring device 5
0, the vehicle body and the optical aimer are directly opposed, and the adjustment screws 20 and 30 are rotated to align the optical axis l of the headlamp with the axle.
At this time, the reference line position 52a does not match the scale zero point position 62a due to variations in the lamp mounting surface on the vehicle body side. Then, the support member 52 is rotated by a screwdriver and moved back and forth in the axial direction, so that the zero point position 62a of the scale of the first inclination measuring instrument coincides with the reference line position 52a. In this way, the scale of the reference line position 52a of the first inclination measuring device 50 is adjusted so as to display the zero point when the lateral illumination angle of the headlamp is at an appropriate position.

On the other hand, in the second inclination measuring device 70 as well, when the headlamp is assembled to the vehicle body, the scale plate 94 may
The zero point position 96a may not match the reference point 72a. In such a case, by shifting the mounting angle of the measuring instrument casing 71 relative to the reflector in the reflector recess 4b, etc.,
Adjustment is made so that the zero point position 96a of the scale 96 is at the reference point 72a position. In this way, when the vertical illumination angle of the headlamp is at the appropriate position, the second
The reference point 72a of the inclination measuring device 70 is adjusted to indicate the zero point 96a of the scale of the scale plate 94.

After that, the user must adjust the illumination angle of the headlamp. When looking into the headlamp from above the upper side wall of the front lens 6, one can see that the reference line position 52a of the first inclination measuring device 50 does not indicate the zero point position 62a of the scale, and that the reference point 72a of the second inclination measuring device 70 does not indicate the zero point position 62a of the scale. If the scale deviates from the zero point position 96a, the amount of inclination of the reflector in the horizontal or vertical direction, that is, the deviation in the irradiation angle of the headlamp in the horizontal or vertical direction can be read from these deviations. In such a case, the adjustment screw 20 or 30
are rotated so that the scale zero point position 62a of the first inclination measuring device 50 comes to the reference line position 52a, and the scale zero point position 96a of the second inclination measuring device 70 comes to the reference point 72a position. Adjust each accordingly. In this way, the irradiation angle of the headlamp in the horizontal or vertical direction can be adjusted.

FIG. 11 shows a movable unit type headlamp with a built-in irradiation angle adjustment mechanism.

A first inclination measuring device 150 for measuring the horizontal inclination of the lamp body and a second inclination measuring device 70 for measuring the vertical inclination of the lamp body are provided on the upper wall 102a of the lamp body 102, respectively. There is. The first inclination measuring device 150 is provided in a horizontal plane including the horizontal swing axis Lx, and a transparent support member 52 is assembled to the mounting surface of the headlamp on the vehicle body 100 side via a holding member 152.
The scaled rod member 54 is urged into contact with a vertical wall 104 projecting from the upper wall 102a of the lamp body. The abutting surface 104a of the rod small diameter portion 61 of the vertical wall 104 is a curved surface centered on the horizontal axis Lx, so that it is not affected by vertical tilting of the lamp body. Furthermore, the scale reading points of the first and second inclinometers 150 and 70 are both provided at positions that are easier to see from above the side surface of the headlamp.

The other configurations are the same as in the case of the movable reflector type described above, and the explanation thereof will be omitted by giving the same reference numerals.

[Effect of idea]

As is clear from the above description, in the automotive headlamp according to the present invention, the irradiation angle of the headlamp can be adjusted by tilting the reflector (lamp body in the case of a movable unit type) vertically and horizontally. The vertical inclination of the reflector (lamp body for movable unit types) can be read with a tilt measuring device, but with this inclination measuring device, the pendulum body is Rotates so that it is always vertical,
This amount of rotation is magnified by a gear mechanism to move the display section of the rotary display body. Therefore, the inclination of the reflector (or the lamp body in the case of a movable unit type) appears as a large deviation between the reference point or scale display on the viewing window and the scale or reference point display on the display section of the rotary display. As a result, anyone can easily adjust the headlamp's beam angle, and in particular, it is easier to read the vertical slope of the headlamp's beam angle, making it possible to adjust the beam angle more accurately and quickly. be able to.
