Background

Such a holding device for a light module, a light module of a light unit and a light unit for a vehicle are known from the prior art in a large number of embodiment variants.

Disclosure of Invention

The invention is started here.

The aim of the invention is to improve the retention of a light module of a light unit of a vehicle.

This object is achieved by a holding device having the features of claim 1, a light module having the features of claim 8 and a lighting unit having the features of claim 10. The dependent claims relate to advantageous further developments of the invention.

A significant advantage of the invention is, in particular, that the maintenance of the light modules of the light-emitting unit of the vehicle is improved. With the invention, it is possible to achieve a significantly more compact and less components for the holding of the light modules of the light-emitting unit of the vehicle. Accordingly, the invention can be advantageously used even in light-emitting units having a small installation space.

In principle, the holding device according to the invention can be freely selected from a wide range of adaptations, depending on the type, function, material, size and arrangement. According to an advantageous further development of the holding device according to the invention, it is provided that the holding device is formed in one piece. In this way, the holding device is further reduced in the number of components required. The transport, storage and assembly of the holding device according to the invention is correspondingly simplified.

In an advantageous further development of the above-mentioned embodiment of the holding device according to the invention, it is provided that the holding device is formed from a spring plate, i.e. a sheet metal part of spring steel. Spring steel has high strength compared to other steels.

According to a further advantageous further development of the holding device according to the invention, it is provided that the bearing section has a positioning aid for positioning the holding device along the longitudinal axis of the bearing pin. This ensures a predetermined and thus predetermined position of the holding device relative to the bearing pin along its longitudinal axis even under difficult conditions of use.

In an advantageous further development of the above-mentioned embodiment of the holding device according to the invention, the positioning aid is designed in such a way that the holding device is elastically pressed against the positioning means of the bearing pin by means of the positioning aid. In this way, a certain tolerance compensation between the bearing pin on the one hand and the retaining device on the other hand can be achieved.

According to a further advantageous further development of the holding device according to the invention, it is provided that the at least one latching means has at least three spring tongues. In the assembled state of the holding device, a reliable latching connection between the holding device and the bearing pin can thereby be achieved. In the case of a limitation to three spring tongues, the orientation of the individual spring tongues relative to one another is furthermore improved and simplified.

A particularly advantageous further development of the holding device according to the invention provides that the fastening section has two positioning aids for positioning the holding device relative to a reference component of the light module. In this way, a desired orientation of the light module relative to the bearing pin and thus relative to the light-emitting unit is ensured in a structurally simple manner by means of the holding device. This relative orientation of the holding device with respect to the reference component of the light module is very important for the proper functioning of the light module. By means of the positioning assistance mechanism, the holding device according to the invention can be referenced to a reference part of the optical module, so that component tolerances when combining the holding device on the one hand and the rest of the optical module on the other hand do not lead to an incorrect position of the optical module in an undesired manner.

Accordingly, according to an advantageous further development of the optical module according to the invention, it is provided that the optical module has two positioning means for positioning the holding device relative to a reference component of the optical module, wherein the two positioning means are each formed corresponding to one of the two positioning aids of the fastening section of the holding device.

Detailed Description

Fig. 1 shows an exemplary embodiment of a light module according to the present invention of a light-emitting unit of a vehicle. The vehicle is designed as a passenger car and the lighting unit is designed as a vehicle headlight. The vehicle and the lighting unit are not further shown in fig. 1 to 3.

The optical module 2 has a plate-shaped cooling body 4 including a heat sink 6 provided thereon. Furthermore, the optical module 2 has a holding device 8, wherein the holding device 8 is screwed to the heat sink 4 by means of a fastening opening 9 in the holding device 8 and a corresponding fastening screw 10. The holding device 8 is formed in one piece in the present exemplary embodiment and is produced from a spring plate, i.e. a single sheet metal part made of spring steel.

The holding device 8 comprises a fastening section 12 for fastening the holding device 8 to the heat sink 4 of the light module 2 and a support section 14 for supporting the holding device 8 on a support pin 16 of the light unit, which is only shown in fig. 3, wherein the support section 14 has a latching mechanism 18, which forms a latching connection with the support pin 16 in the assembled state, not shown, of the holding device 8. The latching mechanism 18 is designed in such a way that the latching connection at the same time forms a joint which enables the rotation of the light module 2 about the longitudinal axis 20 of the bearing pin 16. See fig. 3.

As is evident from fig. 1, the latching mechanism 18 has a total of four spring tongues 22, two of the four spring tongues 22 forming a spring tongue pair that surrounds the bearing pin 16 in the assembled state of the retaining device 8 in a latching manner. For this purpose, reference is also made to fig. 3, in which the retaining device 8 is shown in the transition of the retaining device into its assembled state.

The bearing section 14 of the holding device 8 furthermore has a positioning aid 23 for positioning the holding device 8 along the longitudinal axis 20 of the bearing pin 16, wherein the holding device 8 in its assembled state rests elastically against a positioning means, not shown, of the bearing pin 16 by means of the positioning aid 23. The positioning means, not shown, of the bearing pin 16 are designed as a projection on the bearing pin 16, perpendicular to the longitudinal axis 20 of the bearing pin 16. The positioning aid 23 has two lateral flanks 24 for the elastic contact of the positioning means of the bearing pin 16 against the positioning aid 23.

Furthermore, the fastening section 12 of the holding device 8 has two positioning aids 26 for positioning the holding device 8 relative to a reference component of the light module 2. In the present exemplary embodiment, the two positioning aids 26 are each formed as a circular opening. The reference component of light module 2 is designed as a cover frame 28 of light module 2, wherein all components of light module 2 that are important for the illumination function of light module 2 are positioned, i.e., oriented, relative to cover frame 28 of light module 2.

Correspondingly, all components important for the lighting function of the light module 2 and the holding device 8 refer to the reference component, i.e. the cover frame 28 of the light module 2. Two positioning means which are formed and arranged in correspondence with the above-mentioned positioning aid, i.e. the opening 26, of the holding device 8 are formed on the reference part, i.e. the cover frame 28. The positioning means of the cover frame 28 are constituted as positioning pins 30.

The holding device according to the invention, the light module according to the invention and the lighting unit according to the invention for a vehicle are explained further below according to the present exemplary embodiment and the operating principle thereof with reference to fig. 1 to 3.

First the holding means 8 are present separately from the rest of the light module 2. In order to fasten the holding device 8 of the optical module 2 to the rest of the optical module 2, the holding device 8 is first inserted by means of a fastening clip 32 onto the edges of the heat sink 4, which are shown in the drawing planes of fig. 1 to 3 in each case above. The holding device 8 is at the same time oriented in the desired manner with respect to a reference part of the optical module 2, namely the cover frame 28, since the holding device 8 is inserted with its opening 26 into a positioning means of the cover frame 28, which is designed as a positioning pin 30 and protrudes through a corresponding opening of the heat sink 4. The above-mentioned openings are not shown in the heat sink 4.

The holding device 8 now rests in the desired manner on the heat sink 4 of the light module 2 and the holding device 8 is screwed to the heat sink 4 by means of a total of four fastening screws 10. The holding device 8 is therefore fixed to the heat sink 4. On the other hand, the holding device 8 is oriented in a desired manner relative to a reference component of the light module 2, namely the cover frame 28.

In order to hold the light module 2 on the bearing pin 16 of the light-emitting unit of the vehicle, the holding device 8 is transferred into its assembled state; see in particular fig. 3 for this purpose. In this case, the holding device 8 is pushed onto the bearing pin 16 by means of the latching mechanism 18, i.e. four spring tongues 22 arranged in pairs, in such a way that the spring tongues 22 of the holding device 8 form a latching connection with the bearing pin 16 in the assembled state of the holding device 8, which is not shown. In fig. 3, the holding device 8 is shown in its assembled state, wherein an arrow 33 symbolizes the direction of movement of the bearing pin 16 relative to the holding device 8. The deflection of the spring tongues 22 of the retaining device 8 during the above-mentioned transition into the assembled state of the retaining device 8 is symbolized in fig. 3 by means of a dotted line 34.

As already explained above, the holding device 8 has a positioning aid 23, which corresponds to a positioning means, not shown, formed on the bearing pin 16. Accordingly, the positioning aid 23 of the holding device 8 on the one hand and the positioning means of the bearing pin 16 on the other hand engage with one another when the holding device 8 is transferred into its assembled state, so that the holding device 8 is aligned in the assembled state, not shown, in the desired manner parallel, i.e. along the longitudinal axis 20 of the bearing pin 16. In this case, the side 24 of the positioning aid 23 of the holding device 8 bears elastically against the positioning means of the bearing pin 16.

After the retaining device 8 has been transferred into its assembled state, the light module 2 is rotationally fixed on the bearing pin 16 by means of the retaining device 8 about the longitudinal axis 20 of the bearing pin 16. Correspondingly, the latching mechanism 18 of the holding device 8 forms a latching connection with the bearing pin 16 in the assembled state of the holding device 8, which latching connection at the same time forms a joint which enables a rotation of the light module 2 about the longitudinal axis 20 of the bearing pin 16. Accordingly, in the assembled state of the holding device 8, it is possible to orient the light module 2 in a manner known to the person skilled in the art with respect to a light-emitting unit in which only the bearing pin 16 is shown in fig. 3.

For this purpose, the cover frame 28 of the light module 2 has an adjusting screw connection 36, which can be actuated by means of a screwdriver, not shown. The screwdriver can be inserted into the adjusting screw of the adjusting screw connection 36 by means of an opening 38 in the heat sink 4 of the light module 2. Accordingly, the light module 2 can be pivoted in the respective drawing planes of fig. 2 and 3 about the longitudinal axis 20 of the bearing pin 16, which is shown only in fig. 3, up to a desired deflection position. The light module 2 is then locked in the desired deflection position by means of an adjusting screw connection.

Fig. 4 shows an alternative embodiment of the retaining device. Identical or identically acting components are provided with the same reference numerals. The alternative embodiment of the retaining device 8 shown in fig. 4 corresponds essentially to the embodiment described above with reference to fig. 1 to 3. Accordingly, reference may be made to the above-described embodiments as far as possible. The alternative embodiment of the holding device 8 is therefore only explained in a different context from the holding device 8 according to fig. 1 to 3.

As can be seen from fig. 4, the bearing section 14 of the holding device 8 has only three spring tongues 22. The spring tongues 22 shown below in the plane of the drawing in fig. 4 are constructed analogously to fig. 1 to 3. In the embodiment of the holding device 8 according to fig. 4, the spring tongues 22 shown above in the plane of the views of fig. 1 to 3 are replaced by a single, elongated spring tongue 22, the elongated spring tongue 22 extending along the longitudinal axis 20 of the bearing pin 16 in the assembled state of the holding device 8, which is not shown. The positioning means formed on the bearing pin 16 are in the alternative according to fig. 4 suitably formed in order to engage with the positioning aid 23 when the holding device 8 is transferred into the assembled state.

The present invention is not limited to the present embodiment. For example, the invention can be advantageously used even in other vehicles. The lighting unit according to the invention can also be designed as a vehicle lamp, for example.
