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.
Description
Technical field
The present invention relates to a kind of head lamp leveling equipment of optical axis direction of the head lamp that is used for adjusting vehicle.
Background technology
When the passenger is sitting on the back seat of vehicle, perhaps when luggage is stored in the boot compartment at the rear portion that is arranged in vehicle, the rear portion of vehicle sinks, the result is, even when setting (wherein optical axis is with respect to forward the inclination that is directed downwards) when the optical axis of head lamp is in so-called " dipped beam ", the optical axis direction of head lamp also tends to be inclined upwardly.Therefore, as at for example publication number be the Japanese patent application of 2001-191843 (JP-A-2001-191843), registration number 3016074 Japanese Utility Model, publication number be the Japanese utility model application (JP-U-6-75889) of 6-75889, Japanese Utility Model (JP-Y2-61-23482) that publication number is 61-23482 and publication number be 2004-22324 Japanese patent application (JP-A-2004-22324) in disclosed, the further downward-sloping head lamp leveling equipment of the optical axis that allows head lamp is provided.
Head lamp is set at the left end and right-hand member two places of vehicle front, therefore, must adjust the optical axis orientation of left headlamp and right headlamp.Yet in so-called right hand control car, passenger-seat is positioned at the right side at the center on its Width of vehicle.Therefore, in right hand control car, the distance from the left headlamp to the operating seat is than the distance from the right headlamp to the operating seat.When the handling device of the scaleplate of for example head lamp leveling equipment or lever is set near operating seat for example, and when being connected to left headlamp and right headlamp as the drag-line that the situation handling device of disclosed head lamp leveling equipment among the JP-A-2004-22324 connects engine room via the path, the drag-line of attended operation device and left headlamp is longer than the drag-line of attended operation device and right headlamp.
In by handling device traction cable and the structure of thrust release actuating apparatus to the traction of drag-line by for example propelling unit of rebound spring, drag-line is long more, traction and the required load of return become big more (that is, making the loss of the required load of drag-line displacement become big more).Therefore, in the process of traction and return, the different length of Zola's rope and right drag-line produces the error of the displacement of Zola's rope and right drag-line.These errors cause the difference between the optical axis direction of left headlamp and right headlamp.

Simultaneously, the cardinal extremity that is arranged on the pipe 16 among the pipeline 14R is locked into antetheca 94, than the opposite side (right side) of guide screw 92 more close controller housings 84.The pipeline 14R identical with above-mentioned pipeline 14L has pipe 16 on the structure, passes pipe 16 as the drag-line 18R of second connecting device.Drag-line 18R connects antetheca 94 and is penetrated in the controller housing 84, than the opposite side (right side) of guide screw 92 more close controller housings 84.
Because head lamp unit 12R has the essentially identical structure with above-mentioned head lamp unit 12L, the structure of head lamp unit 12R is not explained in detail.The parts identical with head lamp unit 12L are represented with identical Reference numeral or by suffix " L " is become suffix " R ".
As mentioned above, the controller housing 84 of controller 80 be arranged in vehicle 20 on its Width than the position on more close right side, center, i.e. near position the operating seat of vehicle 20 that is right hand control car.Therefore, is the path being connected to head lamp unit 12R pipeline 14R than more close right side, center on the vehicle-width direction with for example right hand edge on vehicle-width direction along engine room, and the cardinal extremity of pipeline 14R is installed on the controller housing 84, and be the path with for example the left hand edge on vehicle-width direction along engine room at the pipeline 14L that is connected to head lamp unit 12L than more close left side, center on the vehicle-width direction, and further being the path along instrument carrier panel 82 towards controller housing 84, described controller housing 84 is located on the vehicle-width direction position than more close right side, center, and the cardinal extremity of pipeline 14L is installed on the controller housing 84.Therefore, pipeline 14L is longer than pipeline 14R, so drag-line 18L is longer than drag-line 18R.
As mentioned above, locking piece 102 is formed on the cardinal extremity place of the pipeline 14R that is penetrated in the controller housing 84.Lock hole 104R as second installation portion is formed in the slider 88.The locking piece 102 of drag-line 18R is inserted among the lock hole 104R, thereby prevents that locking piece 102 from skidding off lock hole 104R.
As shown in Figure 1, 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.
The action of first embodiment and effect
The following describes action and the effect of first embodiment.
When in according to the head lamp leveling equipment 10 of present embodiment when guide screw 92 is operated 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.Like this towards the slider 88 traction cable 18L of rear wall 86 slips, 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 center displacement more backward 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 center displacement more backward 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 in-to-in head lamp 38 emission that is arranged in each concave mirror 36L, 36R and at the optical axis of the inside face place of each concave mirror 36L, 36R beam reflected.
When guide screw 92 is operated scaleplate 96 rotatably on another direction, cause guide screw 92 axially 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 in-to-in head lamp 38 emission that is arranged in each concave mirror 36L, 36R and at the optical axis of the inside face place of each concave mirror 36L, 36R beam reflected.
Therefore, in head lamp leveling equipment 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 head lamp leveling equipment 10 is fully longer than pipeline 14R, and therefore, pipeline 14L can feed 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 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 subjected to bigger 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 in drag-line 18R, produce greater than when the time 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

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 subjected to the sliding resistance bigger 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 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 the value of the power on the neighboring of lock hole 104L, 104R opposite with in the return process 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 is caused that by the thrust of compression disc spring 30L, 30R quilt weakens along the sliding resistance of 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

In head lamp leveling equipment 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 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 MR (=FR in the generation of the lock hole 104R place of slider 88
2* Y).For this reason, guide screw 92 and slider 88 bonded assembly connection locations are set as follows: same in the return process of drag- line 18L, 18R, and the always satisfied FL that concerns of distance X and distance Y
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, can make the moment ML that acts on the lock hole 104L greater than the moment MR that acts on the lock hole 104R greater than the power that acts on the lock hole 104L.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.
Second embodiment structure
The following describes another embodiment of the present invention.Below among Shuo Ming the embodiment, represent the parts that are equal to substantially with the parts that comprise the previously described embodiment of first embodiment with identical Reference numeral, and omit its detailed description.
Fig. 6 shows the section-drawing with the schematic configuration of the relevant portion of the corresponding head lamp leveling equipment 130 according to a second embodiment of the present invention of Fig. 1.
As shown in the drawing, head lamp leveling equipment 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 first embodiment, internal thread hole 100 is formed in the slider 134.Guide screw 92 connects internal thread hole 100.Different with the situation of slider 88, lock hole 104L is formed between internal thread hole 100 and the lock hole 104R.
The action of second embodiment and effect
In having the head lamp leveling equipment 130 of 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 makes the error of displacement of the displacement can prevent drag-line 18L in traction and return process and drag-line 18R 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 show with Fig. 1 in the section-drawing of schematic configuration of relevant portion of the corresponding head lamp leveling equipment 160 according to present embodiment of structure.
As shown in the figure, head lamp leveling equipment 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 in first embodiment 88, 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 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 head lamp leveling equipment 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 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 bigger 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 makes drag-line 18R at first begin displacement, causes the displacement of two cardinal extremities of drag- line 18L, 18R error to occur.
Therefore, in head lamp leveling equipment 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, lock hole 104R goes up and than the big moment MR of moment ML that acts on the lock hole 104L, when antetheca 94 is pulled, near the position of the lock hole 104R of slider 164 is easy to elastic deformation owing to acting on.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, can simplify the structure of slider 164 with on the meaning of the different material of the modulus of elasticity of lock hole 104R place 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, since act on the lock hole 104R and than the big moment MR of moment ML that acts on the lock hole 104L, 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 makes the error of displacement of the displacement can prevent to amplify drag-line 18L and drag-line 18R, and makes and 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, thereby slider 164 always tilts on the orientation of moment MR with 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 makes and can prevent in traction and retract the displacement that amplifies drag-line 18L in the process and 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 the distance setting by will be from internal thread hole 100 to lock hole 104R for than the distance from female screw hole 100 to lock hole 104L (promptly, by growing to the distance W of the line of centers of lock hole 104L to being set at than line of centers of line of centers of lock hole 104R from the line of centers of guide screw 92 from guide screw 92 apart from V), can make near the position of the lock hole 104R of slider 164 be easy to elastic deformation.Yet in another embodiment, near the rigidity at position that can make lock hole 104R is 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 material of the slider 164 at position near the position lock hole 104L and the lock hole 104R near the position lock hole 104L near the position 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 littler 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 the foregoing description.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 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 to make the structure of slider 88,134,164 reverse in this case.
