Description

Motor vehicle headlight regulating assembly
Invention refers to a motor vehicle light regulating assembly and belongs to vehicles, namely to vehicle lights, which are adjustable with mechanical means.
The purpose of the invention is to create such motor vehicle light regulating assembly, by which potential overloading of each exposed components of the regulating assembly as such by turning a regulating spindle in one direction or optionally in both directions could be eliminated by means of limiting a torque, by which also reliability of adjusting a reflector within a light casing could be improved, and at the same time, such assembly should consist of components, which could be simply manufactured and should also be universally applicable in various lights which may be used in various vehicles.
A motor vehicle light regulating assembly is described in EP 0 857 608 Al . Respective light essentially consists of a casing, in which a light source is inserted together with a belonging reflector. Said casing can be in each desired position mounted into each desired vehicle. In order to assure appropriate operation, in particular a correct distribution of light beams in the area in front of the vehicle, each appropriate position of the reflector needs to be adjusted as soon as the light is mounted into each vehicle, and when needed also subsequently during the use, so that the reflector is then capable to collect and to redirect light beams towards said area in front of the vehicle. Each position of the reflector can generally be adjusted by means of a regulating screw, which is with the possibility of rotating embedded within the casing, as well as of a spindle, which is interconnected with the reflector. Said screw is furnished with a gear, which is adapted to cooperate with a gear, which is available on said spindle, which extends throughout a nut or threaded bush, which is formed within the casing or integrally therewith. When the screw is rotated, torque is transmitted via said gears on the spindle, which is embedded within said bush and is therefore axially displaced, which thanks to its interconnection with the reflector results in displacement or pivoting of the reflector in one or another direction, respectively. In order to obtain a desired transmission rate, the thread on said spindle and said bush is usually a fine metric thread, wherein a competitive manufacturing technology of vehicle light is based on a mass production of lights, wherein also the majority components, where possible, consist of materials on the basis of thermoplastic polymers. Components can be definitively manufactured within each defined tolerances, but subsequent changes of dimensions and the shape of said components due to the nature of polymers may often occur due to releasing of residual tensions and other phenomena. When such regulating assembly is completed, by taking into consideration said phenomena on the one hand in the area of the casing and on the other hand in the area of embedding the reflector, each friction among said components during the practical use may essentially vary. Of that reason, the torque required for turning the spindle and adjusting each position of the reflector may also vary, and on the other hand also the components of such regulating assembly are deformed in various manners. It happens that a relatively high torque must be available for the purposes of displacing the reflector, which then results not only in displacement of said reflector but also in increasing of loadings and stresses within certain components, which are then essentially deformed. Even when each desired position of the reflector has already been adjusted, said releasing of tensions and deformation of components may occur in the regulating assembly as such, by which the adjusted position of the reflector is changing in an uncontrolled manner. When modern screwing tools are used, such problems are still multiplied. When considering the solution according to EP 0 857 608 Al, the consequence can be disengagement of gears on the screw and the spindle, or disengagement between the spindle and the threaded bush. In such case said components are exposed to plastic deformation and serious damages. More frequently, friction between the spindle and the bush may be increased in such extent that the spindle is unable to rotate in one or another direction, by which the regulating assembly is completely disabled.
The invention refers to a motor vehicle light regulating assembly, which is intended for adjusting each desired position of a reflector independently or simultaneously with a belonging light source relative to a light casing, wherein such regulating assembly comprises a spindle, which is adapted to cooperate with a threaded bore in the vehicle casing and comprises a first end portion, which protrudes towards the interior of said casing and is adapted to cooperate with the reflector, as well as a second end portion, which protrudes outwards from the casing and is interconnected with a female part, which is intended to cooperate with a suitable torque generating tool, by means of which said spindle can be rotated and axially displaced for the purposes of adjusting each desired the position of the reflector, which is at least indirectly connected therewith.
The invention provides that said female part is conceived both to enable cooperation with a torque generating tool and also to form a part of a coupling, which consists of said female part and a male part, which is positively interconnectable therewith in order to enable transmission of a limited torque only and which is on the other hand interconnected with an outside of the light casing protruding end portion of a spindle.
In a preferred embodiment of the invention, said male part of the coupling is sufficiently rigid and comprises certain number of radial ribs, which are equidistantly arranged along the circumference thereof, as well as recesses, which are arranged there-between, and that the female part, which is at least in the area of cooperation with said male part sufficiently resilient and elastically deformable in the radial direction, comprises certain number of segments, which are equidistantly arranged along the circumference thereof and at least a part of them are furnished with a radially inward directed protrusion, which is adapted to cooperate with each corresponding rib and/or each corresponding recess on the male part.
In one of further embodiments of the invention, flanks of each rib and/or each recess on the male part of the coupling are symmetric with respect to each corresponding radial geometric axis, which extends throughout each rib. In such case, flanks of each protrusion on each segment of the female part of the coupling are also symmetric with respect to each corresponding radial geometric axis, which extends throughout each rib.
In a still further embodiment of the invention, flanks of each rib and/or each recess (on the male part of the coupling are asymmetric with respect to each corresponding radial geometric axis, which extends throughout each rib. In such case, flanks of each protrusion on each segment of the female part of the coupling are also asymmetric with respect to each corresponding radial geometric axis, which extends throughout each rib. In this, one flank of each rib and/or each recess on the male part of the coupling is formed as inclination, and each residual flank is formed as at least approximately in radial direction extending shoulder, wherein the shape and arrangement of flanks on each disposable ribs on the male part are accommodated to transmission of torque in each desired direction of rotation of the coupling and consequently of the spindle. Correspondingly to that, one flank of each protrusion on each segment on the female part of the coupling is formed as an inclination, and each residual flank is formed as at least approximately in radial direction extending shoulder, wherein the shape and arrangement of flanks on each disposable protrusions on segments on the female part are accommodated to transmission of torque in each desired direction of rotation of the coupling and consequently of the spindle. The invention will be described in more detail by means of two embodiments, which are shown in the attached drawing, where
Fig. 1 is a schematically presented motor vehicle headlight regulating assembly along the vertical plane of the headlight;
Fig. 2 is the first embodiment, namely a cross-section thereof along the plane A - A according to Fig. 1 ; and
Fig. 3 is the second embodiment, namely a cross-section analogously like in Fig. 2.
A motor vehicle headlight according to Fig. 1 consists of a casing 1 with a transparent front wall 11, a light source 2 and a reflector 3 which is intended for redirecting of light beam generated by the light source 2 throughout said front wall 11 towards each corresponding area in front of the headlight.
Said reflector 3 is allowed to be displaced relative to the casing 1 either together with the light source 2 or independently there-from at least to such, extent that by means of adjusting each desired position of said reflector 3, in particular by means of rotation thereof around its horizontal axis, which extends transversally with respect to the coaxially with the light source 2 extending longitudinal axis of the light, the direction of light beams can be adjusted towards at least those areas, which are prescribed by regulations allowing the use of such the light in the traffic. To this aim, the reflector 2 is interconnected with a regulating assembly 4 serving to adjust each desired position of the reflector 3 relative to the casing 1.
The regulating assembly 4 consists of a spindle 40, which is furnished with a thread 41, which is adapted to cooperate with a threaded bore 14 in the casing 1. The spindle 40 comprises s protrusion 401 located on towards the interior of the casing 1 faced end portion 40' thereof, and is adapted to cooperate with a corresponding seat 34 on the reflector 3, wherein in the shown embodiment said reflector 3 is supported by means of a spring 31, which is inserted between said seat 34 of the reflector 3 and the casing 1 and by means of which the seat 34 is then pressed towards the protrusion 401 of the spindle 40. The opposite end portion 40" of the spindle 4 protrudes outwardly from said casing 1 and is furnished with appropriately formed protrusion 402, which is adapted to establish a positive interconnection between the spindle 4 and the coupling 44. Said protrusion 402 enables transmission of torque from the coupling 44 to the spindle 40 e.g. by means of appropriately shaped profile in the form of a square or a hexagon or the like. Moreover, a gasket 43 is foreseen in the area of said protrusion 402, which is in the shown embodiment preferably an O-ring and which prevents the moisture and impurities from entering into the area of said spindle 40 within the casing 1 from the outside of the casing 1.
The coupling 44 consists of a male part 441, which is in the shown embodiment interconnectable with said spindle 40, as well as of a female part 442, which is in the shown embodiment adapted to cooperate with a not shown torque generating tool, which is used for the purposes of rotating the spindle 40, e.g. with a hand-operated screwdriver, or optionally with appropriate socket of an electric screwing machine.
Said male part 441 of the coupling 44 is an uniform and relatively rigid part and is furnished with a plurality of outwardly protruding ribs 4411, which are equidistantly arranged around the circumference and separated by appropriately shaped recesses 4412. On the contrary, the female part 442 of said coupling 44 is at least in the area of contacting the male part 441 relatively elastic and deformable part and is of such reason formed of certain number of segments 4421, wherein at least some of them are furnished with at least one protrusion 4422, which is adapted to cooperate with each corresponding rib 441 1 or each corresponding recess 4412 of the male part 441 of the coupling 44.
As a result, the coupling 44 is capable to transmit just a limited torque, by which elastic deformations of said segments 4421 in the assembly of the male part 441 and the female part 442 still allow maintaining a positive interconnection between the protrusions 4422 on the female part 442 and the ribs 4411 or recesses 4412 on the male part 441. Whenever the coupling 44 is exposed to excessive torque, each segment 4421 on the female part 442 is elastically deflected in the radial direction, and the engagement between each corresponding protrusion 4422 with the rib 441 1 or the recess 4412 on the male part 441 is temporarily eliminated, and said positive interconnection between the male part 441 and the female part 442 of the coupling 44 in the sense of transmission of the torque is temporarily interrupted.
A simplified embodiment of the regulating assembly 4 with a corresponding coupling 44 is shown in Fig. 2. In such case, the ribs 4411 on the male part 441 of the coupling 44 are arranged symmetrically with respect to each corresponding radial geometric axis, and the same applies also for the recesses 4412 between said ribs 4411. Analogously, protrusions 4422 on radial deformable elastic segments 4421 on the female part 442 are also arranged symmetrically. As a result, the coupling 44 is capable to transmit a pre-determined torque, which depends on each pre-determined elasticity or rigidity of said segments 4421 on the female part 442, and which the same by rotating the female part 442 or also the spindle 40 in one or another direction.
On the contrary, a further embodiment of the coupling 44 is shown in Fig. 3, which is able to transmit different torque in one or another direction. In such embodiment, at least some of protrusions 4422 on the female part 442 are furnished with inclinations 4422' on the one flank and radial shoulders 4422" on the opposite flanks, and correspondingly, at least some of ribs 4411 and/or some of recesses 4412 on the male part 441 are furnished with inclination 441 on the one flank and with a radial shoulder 4411 " on the other flank. With respect to arrangement as shown in Fig. 3, it is obvious that by rotating the female part 422 of the coupling 44 clockwise, segments 4421 of the female part 441 are deflected at lower torque than by rotating counterclockwise, so that capabilities of torque transmission by means of such coupling 44 when rotating in one or another direction are different.
