The reflector has at least one pivot axis, the reflector being rotatably supported in the inner region of the housing about the pivot axis. The adjustment element comprises a rotation axis, an adjustment portion and an engagement portion, wherein the adjustment element also passes through the housing, the adjustment portion extending into the outer region and the engagement portion extending into the inner region, wherein the adjustment element is also rotatably supported at the housing about the rotation axis, wherein the adjustment portion is designed to accommodate an adjustment tool, such that the adjustment element can be rotated about its rotation axis by means of the adjustment tool. BACKGROUND
[0002] Such vehicle lamps are known from the prior art and usually have a plurality of individual components in order to achieve the adjustment of the reflector. SUMMARY
[0003] It is therefore an object of the invention to provide a vehicle lamp with simplified adjustment.
[0004] This object is achieved by the vehicle lamp described above, wherein the reflector is integrally formed with a gearwheel, the gearwheel having a plurality of teeth which at least partially engage with the engagement portion of the adjustment element, such that a rotation of the adjustment element about its rotation axis causes a rotation of the reflector about its pivot axis.
[0005] By "integrally formed" is meant that the reflector and the gearwheel are made of one piece of material. Preferably, the reflector and the gearwheel are formed together by means of an injection molding process, the reflector and the gearwheel being made of a first component, wherein the first component is a heat-resistant material, in particular polycarbonate.
[0006] Advantageously, the reflector (20) and the gearwheel (22) can be formed together by means of a two-component injection molding process, wherein the reflector is made of a first component and the gearwheel (22) is made of a second component, the first component being a heat-resistant material, in particular polycarbonate, wherein the first component is different from the second component.
[0007] By heat-resistant material is meant a material which remains substantially stable in shape at an upper limit temperature. The upper limit temperature is for example 120°C.
[0008] In order to achieve a uniform adjustment, the gearwheel can be designed in a circularly symmetrical shape, wherein the center of the gearwheel coincides with the pivot axis of the reflector.
[0009] Furthermore, the pivot axis is oriented substantially in horizontal direction with respect to the mounting position of the vehicle lamp.
[0010] In order to further reduce the number of components, the reflector can be rotatably supported at at least two suspension regions of the inner region about the pivot axis, wherein the suspension regions each have a support for the reflector which is formed integrally with the housing.
[0011] If the at least one suspension region, preferably each suspension region, and their support have a locking connection which fixes the reflector in the inner region in a direction perpendicular to the pivot axis, rapid assembly is possible, preferably the locking connection is formed integrally with the housing.
[0012] Advantageously, the engagement portion of the adjustment element can be designed as a second gearwheel, preferably as a circularly symmetrical gearwheel, wherein the center of the second gearwheel coincides with the rotation axis, wherein the second gearwheel has a plurality of second teeth, wherein the second teeth of the second gearwheel are in contact at least in sections with the first teeth of the gearwheel which is formed integrally with the reflector.
[0013] When the angle between the pivot axis and the rotation axis is between 50° and 130°, preferably substantially 90°, stable adjustment is possible, preferably the gearwheel which is formed integrally with the reflector and the second gearwheel are designed as bevel gears.
[0014] Here, the rotation axis is oriented substantially in the vertical direction relative to the mounting position of the vehicle lamp.
[0015] The mounting position of the vehicle lamp corresponds to the normal or reasonable position of the vehicle lamp in the vehicle. The terms "horizontal direction" and "vertical direction" refer to directions which are orthogonal to one another.
[0016] Advantageously, the adjustment element is fixed in the inner region in a direction perpendicular to the rotation axis by means of a second locking connection, wherein preferably the second locking connection is formed integrally with the housing.
[0017] In particular, it is possible to design the adjustment element to be supported at least at one of a first holding region and a second holding region, wherein the first holding region has the second locking connection, the first holding region being formed in the region of the adjustment portion along the rotation axis, wherein in the second holding region the adjustment element is fixed in the direction of the rotation axis, the second holding region being formed in the region of the engagement portion along the rotation axis.
[0018] If the vehicle headlamp has a second adjusting element, a multifunctional adjustment can be achieved, which has a second axis of rotation, a second adjusting portion and a second engagement portion, which also passes through the housing such that the second adjusting portion extends into the outer region and the second engagement portion extends into the inner region, wherein the second adjusting element is rotatably supported at the housing about the second axis of rotation, wherein the teeth of a gear wheel which is formed integrally with the reflector at least partially come into contact with the engagement portion of the second adjusting element, such that a rotation of the second adjusting element about the second axis of rotation causes a rotation of the reflector about the pivot axis.
[0019] If the adjusting element and the second adjusting element have the same structure, a cost-effective design can be achieved.
[0020] It is particularly advantageous if the second axis of rotation coincides with the axis of rotation and the further adjusting portion of the second adjusting element is located opposite the adjusting portion of the adjusting element with respect to the housing. BRIEF DESCRIPTION OF DRAWINGS
[0021] Possible embodiments of the application are explained below by way of description of the drawings, but the application is not restricted to the embodiments shown.
[0022] Figure 1 A partial cross-sectional view of a vehicle headlamp is shown;
[0023] Figure 2 A partial cross-sectional view of a vehicle headlamp according to another embodiment is shown. DETAILED DESCRIPTION
[0024] Figure 1 The vehicle headlamp 1 shown is in an orientation corresponding to its installed position in a vehicle (not shown). V denotes the vertical direction and H denotes the horizontal direction. The vertical direction V and the horizontal direction H are perpendicular to one another. The vehicle headlamp 1 can be embodied, for example, as a fog lamp.
[0025] The vehicle headlamp 1 has a housing 10, a reflector 20 and an adjusting element 30.
[0026] The housing 10 delimits an inner region 2 and an outer region 3 and at least partially, preferably completely, encloses the inner region 2. The housing 10 generally comprises an at least partially transparent portion, which can be referred to as a cover plate (not shown), and a non-transparent portion. The at least partially transparent portion and the non-transparent portion are generally connected to one another to form a substantially closed housing. The inner region can be substantially completely isolated from the outer region. It is clear that this does not necessarily mean that the isolation must be airtight. It is known to the person skilled in the art that some common measures, such as a ventilation element, can maintain an atmospheric connection between the inner region 2 and the outer region 3. In assembly, the transparent component is generally glued to the non-transparent component after the elements have been mounted in the housing 10.
[0027] A reflector 20 is arranged in the inner region 2. The reflector 20 has a pivot axis 21 and is rotatably supported about the pivot axis 21. The reflector 20 can deflect light of a light source (not shown) into a direction which is both perpendicular to the horizontal direction H and perpendicular to the vertical direction V. The mounting position in the vehicle can correspond to the driving direction of the vehicle.
[0028] Furthermore, an adjustment element 30 can be seen. The adjustment element 30 has a rotational axis 31, an adjustment portion 32 and an engagement portion 33. The adjustment element 30 passes through the housing 10. The adjustment portion 32 of the adjustment element 30 is located in the outer region 3 and the engagement portion 33 is located in the inner region 2. The adjustment element 30 is rotatably mounted on the housing 10 about its rotational axis 31.
[0029] The rotational axis 31 is oriented substantially in the horizontal direction V in the mounting position of the vehicle lamp.
[0030] The adjustment portion 32 is designed to accommodate an adjustment tool (not shown). This means that the adjustment portion 32 has, for example, a recess or a shaped structure which corresponds to the adjustment tool. The recess or shaped structure is configured such that the adjustment tool can rotate the adjustment element 30 about its rotational axis 31.
[0031] The reflector 10 is integrally formed with a gear wheel 22. The gear wheel 22 has a plurality of first teeth 23 which partially engage with the engagement portion 33 of the adjustment element 30. Thus, by rotating the engagement portion 33 of the adjustment element 30 with the adjustment tool, the reflector 10 is caused to rotate about its pivot axis 21.
[0032] The reflector 10 can be integrally formed with the gear wheel 22 by means of an injection-moulding process. The reflector 10 and the gear wheel 22 can be made from the same first component, which is a heat-resistant material, preferably polycarbonate (PC).
[0033] It is particularly preferred that the reflector 10 can be made of a first component, while the gear wheel 22 is made of a second component. The second component is different from the first component. The second component can for example be made of glass fiber reinforced polybutylene terephthalate (PBT) or polyamide (PA). If the reflector 10 and the gear wheel 22 are made of different components, they can be manufactured or shaped by a two-component injection molding process.
[0034] The gear wheel 22 can have a circularly symmetrical shape, the center of the gear wheel 22 preferably coinciding with the pivot axis 21 of the reflector 20.
[0035] As shown, the rotation axis 21 is preferably oriented in a horizontal direction H. This horizontal direction H is related to the mounting position of the vehicle lamp 1 in the vehicle, as described before.
[0036] The reflector 20 is rotatably supported around the pivot axis 21 in the two suspension regions 11, 12 of the inner region 2. This support allows the reflector 10 to rotate at least around its pivot axis 21. The suspension regions 11, 12 and their support can be integrally formed with the housing 10.
[0037] One of the suspension regions 11, 12 can have a locking connection 13. This locking connection 13 prevents the reflector 20 from moving in a direction perpendicular to the pivot axis 21 after the reflector 20 is mounted to the housing 10. In combination with the suspension regions 11, 12 and their support, the reflector 20 is fixed in all directions perpendicular to the pivot axis 21 after mounting and movement along the pivot axis 21 is prevented.
[0038] The engagement 33 of the adjustment element 30 can be designed as a second gear wheel 34. This second gear wheel 34 can have a circularly symmetrical shape, wherein the center of the second gear wheel coincides with the rotation axis 31 of the adjustment element 30. The second gear wheel 34 has a plurality of second teeth 35, which at least partially contact the first teeth 23 of the gear wheel 22 integrally formed on the reflector 20.
[0039] An angle is formed between the rotation axis 31 and the pivot axis 21. In the shown embodiment, this angle is 90°. Either the gear wheel 22 integrally formed with the reflector 10 or the second gear wheel 34 is designed as a bevel gear. The angle between the rotation axis 31 and the pivot axis 21 is not limited to the mentioned value, but can also vary between 50° and 130° by correspondingly adapting the shape of the bevel gear.
[0040] The adjustment element 30 is fixed in the inner region 2 by a second locking connection 14 in order to prevent a movement of the adjustment element in a direction perpendicular to the rotation axis 31. This second locking connection 14 is preferably integrally formed with the housing 10. In combination with the bearing of the adjustment element 30 in the housing, the adjustment element 30 is fixed in all directions perpendicular to the rotation axis 31 after mounting and is prevented from moving along the rotation axis 31.
[0041] Two holding regions 36 and 37 are shown. The adjustment element 30 is rotatably supported in the first holding region 36 and in the second holding region 37. The first holding region 36 has the second locking connection 14, wherein the first holding region 36 is formed in the region of the adjustment portion 33 along the rotation axis 31 and the second holding region 37 is formed in the region of the engagement portion 32 along the rotation axis 31.
[0042] Figure 2 A vehicle headlamp 1 according to a further embodiment is shown. In this embodiment, the vehicle headlamp 1 is shown as Figure 1 wherein the vehicle headlamp further has a second adjustment element 40. This second adjustment element 40 has a second rotation axis 41, a second adjustment portion 42 and a second engagement portion 43. The second adjustment element 40 passes through the housing, the second adjustment portion 42 extends into the outer region 3 and the second engagement portion 42 extends into the inner region 2. The second adjustment element 40 is similar to the adjustment element 30 and can be rotated in the housing 10 about the second rotation axis 41.
[0043] The first toothing 23 of the gear wheel 22 integrally formed with the reflector 20 is at least partially engaged with the second engagement portion 43. Thus, by rotating the second adjustment element 40 about the second rotation axis 41, a rotation of the reflector 20 about the pivot axis 21 can be achieved.
[0044] In order to save costs, the adjustment element 30 and the second adjustment element 40 can be designed identically and congruently.
[0045] Furthermore, as shown, the second rotation axis 41 can coincide with the rotation axis 31. In this case, the second adjustment portion 42 can be arranged opposite the adjustment portion 32 of the adjustment element 30 with respect to the housing 10. At this time, the second rotation axis 41 and the rotation axis 31 preferably extend in the perpendicular direction V.
[0046] The individual aspects or embodiments of the invention can be adopted individually and in combination with one another. The reference signs in the claims are merely exemplary and are intended to improve the readability of the claims and do not constitute any limitation on the scope of the claims.
