The utility model discloses an automobile ornament can be applied to the automobile ornament of similar automobile front and back skylight, car grille and bumper, automobile front and back headlight, automobile front and back fender, rear-view mirror and tail-gate etc. department.
The first embodiment is as follows:
as shown in fig. 1 to 3, an automobile trim having a filter coating 10 and a seamless integrated lidar 3 mainly comprises: the decoration piece comprises a decoration piece body 1, a mounting framework 2 and a laser radar 3.
It should be explained that the function of the filter coating 10 is mainly to ensure that light in a predetermined wavelength band is transmitted, and to filter light in other wavelength bands so as not to influence the operation of the lidar 3 by light in other wavelength bands. The filtering coating 10 may be specifically a filtering PC or a filtering PMMA, and considering the actual loss of light, it is generally required to ensure that the transmittance of the filtering coating for the light with the wavelength band of 905 ± 20 nm and/or 1350 ± 20 nm reaches above 90%, and the transmittance for the light with other wavelength bands is below 5%. Namely: most of light in a preset waveband can pass through the light source, but the light cannot be transmitted by 100% actually; most light which is not in the preset wave band can not pass through, and the interception of 100% is difficult to realize.
The whole surface covers on the internal surface of gadget body 1 has filtering coating 10, compare and only have filtering coating 10 to radar window area 15, and other regions adopt the paint to cover to when guaranteeing that radar window area 15 has the filtering action, other regions can shield the inner structure of automobile gadget, this just need when carrying out the paint cover process, need shield radar window area 15, otherwise the paint enters into and can influence the filtering effect in radar window area 15. In the embodiment, the filter coating 10 is covered on the whole surface, and the radar window area 15 is not required to be covered in the coating process.
The light filtering coating 10 is provided with a hardened layer 11, the hardened layer 11 is provided with an anti-reflection layer 13, the anti-reflection layer 13 is located on one side far away from the light filtering coating 10, and only one-side hardening treatment and no two-side hardening are needed for the light filtering coating 10. The hardening layer 11 is used for enhancing the strength of the light filtering coating 10 to adhere the antireflection layer 13, the antireflection layer 13 is used for increasing the transmittance of light in the preset wavelength band, if the light filtering coating 10 is not hardened, the electroplating of the antireflection layer 13 is affected, and after the light filtering coating 10 is hardened, the hardness is sufficient, so that the weather resistance requirement can be met. The hardened layer 11 may be, but is not limited to, HC.
In an actual using process, the inner surface of the ornament body 1 is directly covered with the filtering coating 10, the filtering coating 10 can be penetrated by light with a preset waveband, so that the normal operation of the laser radar 3 is ensured, and for the ornament body 1 made of transparent plastic, the filtering coating 10 can play a role of shielding an internal structure, namely a clown; because the whole surface of the ornament body 1 is covered with the light filtering coating 10, no obvious material boundary line exists when the automobile ornament is seen from the outside to the inside, and the good appearance of the automobile ornament can be ensured. That is, the filter coating layer 10 functions as a filter layer and also functions as a shielding coating layer, and the step of applying the shielding coating layer is omitted. After the inner surface of the ornament body 1 is directly covered with the filter coating 10, the filter coating 10 at the radar window area 15 can be hardened by the setting of the hardening layer 11, after the hardening layer 11 is attached, the hardening layer 11 can be directly coated with the anti-reflection layer 13, the heating layer 14 and the like, the insert injection molding or viscose glue fixing process is not needed, and the manufacturing process can be effectively saved.
Specifically, a radar window area 15 is formed at a position, opposite to the laser radar 3, on the ornament body 1, the anti-reflection layer 13 and the hardened layer 11 are both located in the radar window area 15, and therefore only small-area film coating treatment needs to be carried out on the ornament body 1 with a large area.
Referring to fig. 1 again, the laser radar 3 is disposed on the mounting frame 2 and is fixedly connected to the mounting frame 2. Wherein, be equipped with installation department 20 and lower installation department 21 on the installation framework 2, just go up installation department 20 with all be equipped with reference column 22 on the lower installation department 21, be equipped with on laser radar 3 with the locating hole of reference column 22 one-to-one, reference column 22 wears to establish in the locating hole, be equipped with the conical head of certain length at the head of reference column 22, this conical head diminishes from last sectional area down gradually to conveniently install laser radar 3 on reference column 22, when looking for, be unlikely to too high to the position requirement, laser radar 3 with go up installation department 20 with installation department 21 is fixed connection down, preferably through screw detachably fixed connection, convenient dismantlement, change laser radar 3.
Referring to fig. 2 again, a transverse support plate 23 is arranged on the mounting framework 2, the transverse support plate 23 is located below the laser radar 3, and the laser radar 3 is supported on the transverse support plate 23; the transverse support plate 23 is provided with a through hole 230, the laser radar 3 is provided with a threaded hole 30 corresponding to the through hole 230, the adjustable screw 40 penetrates through the through hole 230 from bottom to top and is in threaded connection with the threaded hole 30, and the adjustable screw 40 can absorb Z-direction installation errors of the laser radar 3 on the transverse support plate 22.
In the embodiment, the mounting framework 2 is separately made into a part and is not integrated with the ornament body 1 and the filter coating 10, so that the structure of the mounting framework 2 can be made more complicated, the mounting framework 2 can provide better support strength to sufficiently support the laser radar 3 with heavier weight, a support plate is arranged on the mounting framework 2 along the bottom of the laser radar 3, the whole weight of the laser radar 3 is supported on the support plate, a cantilever beam structure is prevented from being formed, and the laser radar 3 cannot loosen or fall off under various severe road conditions when an automobile runs; and the ornament body 1 is simple in structure and convenient to form.
Example two:
as shown in fig. 4, a difference between this embodiment and the first embodiment is that a heating layer 14 is further disposed on the hardened layer 11, the heating layer 14 and the antireflection layer 13 are both on the same side of the hardened layer 11, and for the hardened layer 11, the heating layer 14 and the antireflection layer 13 disposed on the same side, the filter coating 10 only needs to be subjected to a single-sided hardening process. The heating layer 14 is arranged to heat the ornament body 1 so as to achieve the functions of defrosting and demisting.
In conclusion, the automobile ornament has simple manufacturing process and good aesthetic degree.
