Abstract
In a headlamp leveling device (10), the distance from a female-threaded hole (100), at a connecting position between a guide screw (92) and a slider (88), to a locking hole (104L) is sufficiently longer than the distance between the female-threaded hole (100) to a locking hole (104R). As a result, a moment (ML) acting on the locking hole (104L) can exceed a moment (MR) acting on the locking hole (104R). Hence, the slider (88) tilts in the orientation of the moment (ML), both during pulling and pullback of wires (18L, 18R), whereby backlash between the slider (88) and the guide screw (92) is absorbed. This allows preventing magnification of errors in the displacement amounts of the wire 18L and the wire (18R) during pulling and pullback. Differences in the orientation of the optical axes of light beams outputted by respective headlamp units (12L, 12R) can be reduced as a result.

The action of the first embodiment and effect
The following describes action and the effect of the first embodiment.
When in according to the headlamp leveling device 10 of present embodiment when guide screw 92 operates scaleplate 96 in one direction rotatably, guide screw 92 on a described direction around himself axle rotation.Therefore, slider 88 moves towards rear wall 86.The slider 88 traction cable 18L that slide towards rear wall 86 like this, each locking piece 102 of 18R.The traction of locking piece 102 makes two front ends of drag- line 18L, 18R move (displacement) towards its cardinal extremity in the vertical.
The front end of drag-line 18L makes the thrust of front end opposing compression disc spring 30L of drag-line 18L and draw bar 32 towards the motion (displacement) of its cardinal extremity in the vertical, so bar 32 is towards body structure member 22 (that is, roughly towards the rear portion of vehicle) displacement.Bar 32 makes concave mirror 36L towards the motion of body structure member 22 top than concave mirror 36L roughly along the more backward displacement of center of vehicle vertical direction.Therefore, concave mirror 36L pivots around pivot 48, thereby the opening of concave mirror 36L is roughly towards the upper angled of vehicle.
Along with the locking piece 102 of traction cable 18R as mentioned above, the front end of drag-line 18R moves (displacement) towards its cardinal extremity in the vertical, the result, the thrust of the front end of drag-line 18R opposing compression disc spring 30R and draw bar 32, and bar 32 is towards body structure member 22 (that is, roughly towards the rear portion of vehicle) displacement.Bar 32 makes concave mirror 36R towards the motion of body structure member 22 top than concave mirror 36R roughly along the more backward displacement of center of vehicle vertical direction.Therefore, concave mirror 36R pivots around pivot 48, thereby the opening of concave mirror 36R is roughly towards the upper angled of vehicle.
Therefore, become roughly towards the upper angled of vehicle at two openings of concave mirror 36L, the 36R at head lamp unit 12L and 12R place, head lamp unit.Therefore, become roughly towards the upper angled of vehicle by head lamp 38 emission of the inside that is arranged in each concave mirror 36L, 36R and at the optical axis of the light beam of the inside face place of each concave mirror 36L, 36R reflection.
When guide screw 92 operates scaleplate 96 rotatably on another direction, cause guide screw 92 axial-rotation on another direction, slider 88 is slided towards antetheca 94.Along with slider 88 slides towards antetheca 94, removed the traction of slider 88 couples of drag-line 18L, 18R.As mentioned above, the front end of traction cable 18L, 18R by the thrust of compression disc spring 30L, 30R.Therefore, the cardinal extremity of drag- line 18L, 18R is the distance that slider 88 slides towards antetheca 94 towards the distance that its each front end moves (displacement).
The distance that bar 32 moves (that is, roughly moving towards the front portion of vehicle) away from baffle plate 28 equals the displacement (displacement) of drag-line 18L, 18R.Therefore, each concave mirror 36L, 36R pivot around each pivot 48, thereby the opening of each concave mirror 36L, 36R is roughly towards the lower tilt of vehicle.Therefore, at two openings of concave mirror 36L, the 36R at head lamp unit 12L and 12R place, head lamp unit roughly towards the lower tilt of vehicle.Therefore, become roughly towards the lower tilt of vehicle by head lamp 38 emission of the inside that is arranged in each concave mirror 36L, 36R and at the optical axis of the light beam of the inside face place of each concave mirror 36L, 36R reflection.
Therefore, in headlamp leveling device 10, two optical axises of head lamp unit 12L, 12R have a down dip on can be by the rotary manipulation of scaleplate 96.And the pipeline 14L in the headlamp leveling device 10 is fully longer than pipeline 14R, and therefore, pipeline 14L can pass in the device such as engine room, and pipeline 14L cardinal extremity in the vertical arrives near the position the right hand edge on the vehicle-width direction of vehicle 20.This allows controller 80 is arranged in as near the operating seat of the vehicle 20 of right hand control car, thereby makes the passenger who is sitting on the operating seat be easier to (that is, having good operability) operation scaleplate 96.
As mentioned above, pipeline 14L is longer than pipeline 14R, so drag-line 18L is longer than drag-line 18R.Therefore, drag-line 18L is subject to larger sliding resistance along the inner face of pipe 16 than drag-line 18R, thereby operating effort is transferred to the front end of drag-line 18L with relatively poor efficient.Therefore, the tractive force FL that when towards the cardinal extremity traction cable 18L of drag-line 18L, in drag-line 18L, produces
1The tractive force FR that becomes and produce in drag-line 18R greater than when towards the front end of the cardinal extremity traction cable 18R of drag-line 18R
1Therefore, when drag- line 18L, 18R begin being pulled when mobile, act on the power FL on the neighboring of lock hole 104L
1Become greater than the power FR on the neighboring that acts on lock hole 104R
1
Otherwise as drag-line 18L, when 18R begins return, the effect of the thrust of compression disc spring 30L, the 30R at the front end place by being arranged on drag- line 18L, 18R is towards the anterior traction cable 18L of vehicle, the cardinal extremity of 18R.Equally in this case, drag-line 18L is subject to the sliding resistance larger than drag-line 18R along the inner face of pipe 16.Therefore, the transmission efficiency that is transferred to the cardinal extremity of drag-line 18R with thrust from compression disc spring 30R is compared, and the transmission efficiency of cardinal extremity that is transferred to drag-line 18L from the thrust of compression disc spring 30L is relatively poor.Therefore, as drag-line 18L, when 18R begins return, the tractive force FR that produces at the cardinal extremity place of drag-line 18R
2Greater than the tractive force FL in the generation of the cardinal extremity place of drag-line 18L
2, cause acting on the power FR on the neighboring of lock hole 104R
2Greater than the tractive force FL on the neighboring that acts on lock hole 104L
2Therefore following phenomenon appearring: acts on opposite with in the return process of the value of the power on the neighboring of lock hole 104L, 104R in the process of traction cable 18L, 18R.
And, the tractive force FL that in the process of traction cable 18L, 18R, in drag- line 18L, 18R, produces
1, FR
1Greater than the tractive force FL that in the return process of drag- line 18L, 18R, in drag- line 18L, 18R, produces
2, FR
2The reason of this phenomenon is, in distraction procedure, thrust by overcoming compression disc spring 30L, 30R and along the effect of the operating effort of the sliding resistance of the inner face of pipe 16, drag- line 18L, 18R are owing to the power towards its each cardinal extremity traction cable 18L, 18R is in tension, and drag- line 18L, 18R insert by pipe 16.In the return process, the tension of drag- line 18L, 18R causes by the thrust of compression disc spring 30L, 30R, weakened by the sliding resistance along the inner face of pipe 16.That is to say that the tension force that produces (acting on the power on lock hole 104L, the 104R) is observed and concerned FL in drag- line 18L, 18R
1＞FR
1＞FR
2＞FL
2
In headlamp leveling device 10, as mentioned above, the position that is formed in the slider 88 of lock hole 104L and lock hole 104R is set as follows: fully longer than the distance from internal thread hole 100 to lock hole 104R to the distance of lock hole 104L from the internal thread hole 100 as the connection location of guide screw 92 and slider 88.That is to say that the distance X from the line of centers of guide screw 92 to the line of centers of lock hole 104L is set to fully longer to the distance Y of the line of centers of lock hole 104R than the line of centers from guide screw 92.Therefore, when traction cable 18L, 18R, moment the ML (=FL that produces at the lock hole 104L place of slider 88
1* X) inevitable greater than moment the MR (=FR in the generation of the lock hole 104R place of slider 88
1* Y).When making drag- line 18L, 18R return and since distance X become significantly greater than distance Y (that is, and distance X＞＞distance Y), so even at the tractive force FL of drag-line 18L place generation
2Less than the tractive force FR that produces at drag-line 18R place
2, moment the ML (=FL that produces at the lock hole 104L place of slider 88
2* X) greater than moment the MR (=FR in the generation of the lock hole 104R place of slider 88
2* Y).For this reason, guide screw 92 is connected the connection location that connects and is set as follows with slider: same in the return process of drag- line 18L, 18R, distance X and distance Y always satisfy and concern FL
2* X＞FR
2* Y.Therefore, when drag- line 18L, 18R begin return owing to the power of above-mentioned opposite value, as shown in Figure 2, even act on load on the lock hole 104R greater than the power that acts on the lock hole 104L, can make the moment ML that acts on the lock hole 104L greater than the moment MR that acts on the lock hole 104R.The direction of the direction of moment ML and moment MR is all opposite each other in traction and return process.
Therefore, in traction and return process, moment ML is always greater than moment MR.Because the direction of the direction of moment ML and moment MR is opposite each other, deducts orientation that moment MR obtains and that act on the resultant couple MA on the slider 88 from moment ML and have identical direction with the orientation of moment ML.Therefore, slider 88 always tilts on the orientation of moment ML, thereby absorbs the gap between slider 88 and the guide screw 92.Therefore, in traction and return process, can suppress the error of the displacement of the displacement of drag-line 18L and drag-line 18R, cause to reduce the difference of the optical axis direction of the light beam exported by each head lamp unit 12L, 12R.
The second embodiment structure
The following describes another embodiment of the present invention.Among the embodiment of explanation, represent the parts that the parts with the previously described embodiment that comprises the first embodiment are equal to substantially with identical Reference numeral, and description is omitted below.
Fig. 6 shows the section-drawing of schematic configuration of the relevant portion of according to a second embodiment of the present invention the headlamp leveling device 130 corresponding with Fig. 1.
As shown in the drawing, headlamp leveling device 130 has controller 132, rather than controller 80.Controller 132 does not have slider 88, but has the slider 134 as draw gear.As the situation at the slider 88 of the first embodiment, internal thread hole 100 is formed in the slider 134.Guide screw 92 connects internal thread hole 100.Different from the situation of slider 88, lock hole 104L is formed between internal thread hole 100 and the lock hole 104R.
The action of the second embodiment and effect
In the headlamp leveling device 130 with above-mentioned structure, do not consider in the distraction procedure of drag-line 18L, 18R and the tractive force in the return process poor, and do not consider to act on the relation between the relative value of the power on the neighboring of the neighboring of lock hole 104L of slider 134 and lock hole 104R, in a side that forms lock hole 104L and lock hole 104R, towards the part of antetheca 94 traction sliders 134 away from internal thread hole 100, thus slider 134 always tilts and slider 134 and guide screw 92 between the gap be absorbed.That is to say that the direction of the moment ML that produces is identical with the direction of the moment MR that produces in lock hole 104R in lock hole 104L.Therefore, in traction and return process, by moment ML direction that addition obtains with moment MR and that act on the resultant couple MA on the slider 134 is identical with the direction of moment ML and moment MR.Therefore, slider 134 always tilts on the direction of moment ML and moment MR.This be so that can prevent the error of the displacement of the displacement of drag-line 18L and drag-line 18R in traction and return process and amplify, and therefore can reduce the difference of the optical axis direction of the light beam exported by each head lamp unit 12L, 12R.
The 3rd embodiment structure
The following describes the third embodiment of the present invention.
Fig. 7 shows the section-drawing of schematic configuration of the relevant portion of corresponding with the structure among Fig. 1 headlamp leveling device 160 according to present embodiment.
As shown in the figure, headlamp leveling device 160 has controller 162, rather than controller 80.Controller 162 does not have slider 88, but has the slider 164 as draw gear.As the situation of the slider 88 in the first embodiment, internal thread hole 100 is formed in the slider 164.Guide screw 92 connects internal thread hole 100.Yet, being different from slider 88, slider 164 is formed by the material of for example hard rubber material, and this material is than easier elastic deformations such as derbies.
In the slider 88 of the first embodiment, the distance from internal thread hole 100 to lock hole 104L is set to than the distance from internal thread hole 100 to lock hole 104R.Otherwise in the slider 164 of headlamp leveling device 160, the distance from internal thread hole 100 to lock hole 104R is set to than the distance from internal thread hole 100 to lock hole 104L.That is to say that being set to apart from V of the line of centers from the line of centers of guide screw 92 to lock hole 104R is fully longer to the distance W of the line of centers of lock hole 104L than the line of centers from guide screw 92.
The action of the 3rd embodiment and effect
As in the first embodiment, illustrating equally, when drag-line 18L is longer than drag-line 18R, because along the sliding resistance of pipe 16 inner face, the power transmission efficiency of drag-line 18L is poorer than the power transmission efficiency of drag-line 18R.Therefore, traction cable 18L and make drag-line 18L towards its cardinal extremity displacement in the vertical power larger than the situation of drag-line 18R.
Particularly, when slider 164 by scaleplate 96 around guide screw 92 in one direction rotation and when rear wall 86 moves (displacement) (, when traction cable 18L, 18R), two cardinal extremities at drag- line 18L, 18R, the difference of above-mentioned power transmission efficiency causes the displacement of two cardinal extremities of drag- line 18L, 18R error to occur so that drag-line 18R at first begins displacement.
Therefore, in headlamp leveling device 160, the distance from internal thread hole 100 to lock hole 104R is set to than the distance from internal thread hole 100 to lock hole 104L.That is to say that being set to apart from V of the line of centers from the line of centers of guide screw 92 to lock hole 104R is fully longer to the distance W of the line of centers of lock hole 104L than the line of centers from guide screw 92.Therefore, as shown in Figure 8, even the tractive force FL that when traction cable 18L, 18R, in drag-line 18L, produces
1Greater than the tractive force FR that in drag-line 18R, produces
1, act on moment MR on the lock hole 104R of slider 164 greater than the moment ML that acts on the lock hole 104L.That is to say, setpoint distance V so that apart from V＞＞distance W and moment MR (=FR when traction cable 18L, the 18R
1* V) always greater than moment ML (=FL
1* W).The material of slider 164 is easier to elastic deformation than the material of slider 88, and with distance V＞＞mode of distance W sets.Therefore, owing to acting on lock hole 104R upward and likening the large moment MR for the moment ML on the lock hole 104L to, when antetheca 94 is pulled, near the position of the lock hole 104R of slider 164 is easy to elastic deformation.Therefore, make lock hole 104R displacement, so that than the more close antetheca 94 of lock hole 104L.Therefore, not needing to use at lock hole 104L place with on the meaning of the different material of the modulus of elasticity of lock hole 104R place slider 164, can simplify the structure of slider 164.
When slider 164 by scaleplate 96 around guide screw 92 on another direction rotation and when antetheca 94 moves (, when making drag- line 18L, 18R return), because along the sliding resistance of pipe 16 inner face, the thrust of compression disc spring 30L weakens more significantly than the thrust of compression disc spring 30R.Therefore, the tractive force FR of drag-line 18R
2Must be greater than the tractive force FL2 of drag-line 18L.Therefore, same in the process that makes drag- line 18L, 18R return, the moment MR that acts on the lock hole 104R of slider 164 becomes greater than the moment ML that acts on the lock hole 104L.That is to say moment MR (=FR
2* V) inevitable always greater than moment ML (=FL
2* W).That is to say, same in the process that makes drag- line 18L, 18R return, owing to acting on lock hole 104R upward and likening the large moment MR for the moment ML on the lock hole 104L to, when antetheca 94 is pulled, near the position elastic deformation of the lock hole 104R of slider 164.
When traction cable 18L, 18R, owing to the above-mentioned power transmission difference that the difference by the sliding resistance between the pipe 16 causes, at the front end place of drag-line 18L, 18R, drag-line 18R at first begins displacement.Yet as mentioned above, under the effect of the moment MR of the tractive force that depends on drag-line 18R, near the position elastic deformation of the lock hole 104R of slider 164 causes lock hole 104R towards antetheca 94 displacements.This has following effect: the cardinal extremity that suppresses drag-line 18R is corresponding towards the displacement of antetheca 94 with near the position of the lock hole 104R of slider 164 towards the distance that himself front end moves.In turn, this be so that can prevent from amplifying the displacement of drag-line 18L and the error of the displacement of drag-line 18R, and so that can reduce difference by the optical axis orientation of the light beam of each head lamp unit 12L, 12R output.In the traction and return process of drag-line 18L, 18R, moment MR is always greater than moment ML.The direction of the direction of moment ML and moment MR is opposite each other.Therefore, deduct orientation that moment ML obtains and that act on the resultant couple MA on the slider 164 from moment MR and have identical orientation with moment MR, thereby slider 164 always tilts on the orientation of moment MR.That is to say, in a side that forms lock hole 104R, towards the part away from internal thread hole 100 of antetheca 94 traction sliders 164, thus slider 164 always tilts and slider 164 and guide screw 92 between the gap be absorbed.This be so that can prevent in traction and retract in the process displacement that amplifies drag-line 18L and the error of the displacement of drag-line 18R, therefore can reduce the difference by the optical axis orientation of the light beam of each head lamp unit 12L, 12R output.
In the present embodiment, the homogenous material that is easy to elastic deformation by use forms slider 164 and by the distance from internal thread hole 100 to lock hole 104R is set as than the distance from female screw hole 100 to lock hole 104L (namely, by growing to the distance W of the line of centers of lock hole 104L to being set as than the line of centers from guide screw 92 apart from V of line of centers of lock hole 104R from the line of centers of guide screw 92), can make near the position of the lock hole 104R of slider 164 be easy to elastic deformation.Yet, in another embodiment, can make near the rigidity at position of lock hole 104R less than near the rigidity at the position of lock hole 104L.Can also by change at least a portion (for example, use elastomeric material and use metallic material near the position lock hole 104L near the position lock hole 104R) near the material of the slider 164 at position near the position lock hole 104L and the lock hole 104R make slider 164 lock hole 104R near the position be easy to elastic deformation.And, can make near near cross-sectional area position lock hole 104R along the direction of drag-line tractive force effect of slider 164 at position near the position lock hole 104R and lock hole 104L less than near position lock hole 104L, thereby the rigidity difference between near the position of increase lock hole 104R and near the position of lock hole 104L, and make near the position of the lock hole 104R of slider 164 be easy to elastic deformation.The method that increases rigidity difference can comprise, makes near the lock hole 104R of slider 164 plate thickness at position thinner than near the plate thickness at the position lock hole 104L, thereby causes near the position of the lock hole 104R of slider 164 to be easy to elastic deformation.
The invention is not restricted to above-described embodiment.In the above-described embodiments, because embodiment is applied to so-called right hand control car 20, the pipeline 14L that is connected to left headlamp unit 12L is longer than the pipeline 14R that is connected to right headlamp unit 12R.When embodiment being applied to operating seat and being set to the so-called left-hand control car 20 in the left side of center on vehicle-width direction, the pipeline 14R that is connected to right headlamp unit 12R becomes longer than the pipeline 14L that is connected to left headlamp unit 12L.What note is, with respect to disclosed structure in the above-described embodiments, only needs in this case to make slider 88,134,164 structure reverse.
