Detailed Description

In order to deepen the understanding of the present invention, the present invention will be described in detail with reference to the following embodiments, which are only used for explaining the present invention and do not limit the protection scope of the present invention.

In the assembly of the whole lamp to the optical element, especially at present, the functions of the vehicle lamp are increasingly highly integrated, so that the weight of the optical element (whether a reflective reflection bowl or a projection type optical module unit) is increasingly heavier, in order to strengthen the product structure, the assembly of the vehicle lamp provides enough support for the optical unit module with larger weight, a support structure can be added on the vehicle lamp shell to support the optical module unit to bear the weight of the optical module part, and meanwhile, the optical requirement is not influenced. In practice, however, due to deformation of the lamp housing, or thermal requirements, the support structure may deform, making assembly difficult, or severely impossible. In order to solve the problem, a mold of the car lamp shell is required to be maintained, so that certain maintenance cost is increased, and project schedule is influenced. A better solution is to separate the mounting structure here into one small part and fix it to the lamp housing by means of screws. In a short term, assembly with the screws is likely to increase certain cost and working hours, but in a long term, if any problem occurs in the product, the maintenance cost of the product is greatly reduced after the product is detached independently, the period of modification is shorter after the problem occurs in the later stage of the product, and the method has a beneficial effect in terms of practical engineering.

The first embodiment is as follows:

as shown in fig. 1, the supporting frame 1 is cut out from the car lamp housing, and the supporting frame 1 can be made of a material with better strength and rigidity grade. There are 3 first screw holes 1.1, 1.2, 1.3 on support frame 1. The support structure can be mounted stably to the lamp housing 2 by means of screws. The support frame 1 is provided with a groove structure 1.4 for supporting the optical unit module. The advantage of splitting this part alone lies in, can strengthen this individual part's structural strength locally to promote the rigidity of part, compare in prior art and have that the mould feasibility is higher at the scheme that whole car light casing increases additional strengthening, follow-up risk is lower. The separate, separate parts may also be made of a more rigid material, for example PPA. Especially when needing to support above-mentioned optical module that weight is big, reliability and stability can be guaranteed to above-mentioned split part of high rigidity material, need not all increase car light casing bulk rigidity again simultaneously, relatively speaking, and the cost is lower. Meanwhile, the split parts are independently realized through a small die, if the product is positioned or the supporting effect is not good, the die is convenient to change in the later period, and the die modification cost is lower.

As shown in fig. 2, the bracket 3 of the optical unit module is mounted on the vehicle lamp housing 2, and since the optical module has a large weight and is weak below the vehicle lamp housing, the optical unit is easy to be positioned unstably under the heating condition, so that the cut-off line is deviated or shaken, and in order to solve the problem, the bracket 3 of the optical unit module is supported by the support frame 1 alone.

As shown in fig. 3, a groove structure 1.4 on the support frame laterally catches the optical unit bracket so that the optical unit bracket can rotate around this groove, ensuring the feasibility of the adjustment.

Example two:

this embodiment illustrates another form of construction of the invention. Namely a bracket structure of the external installation part of the car lamp and the installation part of the whole car. In order to ensure whether the lamps can meet the requirement of pedestrian protection and meet the requirement of loading, the periphery of the loading support is often made very strong, and then the requirement of regulations on pedestrian protection is met by local weakening. However, for larger lamps, such as vehicle headlamps, the lamp housing is larger and is easily deformed. The common processing scheme is that the whole lamp and the mounting foot are made of the same material and are integrally molded, but the part of the mounting foot is provided with an insert on a mold, and after a product is produced in the later stage, the adjustment is carried out according to the actual condition. According to, in order to increase the structural strength of product, can tear a part alone with the installation foot.

As shown in fig. 4, for the separately detachable vehicular lamp mounting foot structure 4, the separately detachable vehicular lamp mounting foot structure 4 may use the same material as the vehicular lamp housing, but a plurality of supporting ribs are locally formed to increase the rigidity of the structure. Or the product rigidity can be achieved by selecting and using a material with better structural strength without manufacturing too many reinforcing ribs. Simultaneously, the structure is independently disassembled, so that the mold structure of the car lamp shell 2 becomes simpler, and the mold processing and maintenance cost is saved. And the mold for splitting the parts is relatively small, so that the influence of injection molding on the product can be avoided.

As shown in fig. 5, which is a schematic view of the lamp mounting base structure 4 and the mounting possibility of the lamp mounting base structure 4 shown in fig. 4, the lamp mounting base structure 4 has three second screw holes 4.1,4.2,4.3, and is fastened to the lamp housing 2 by three screws.
