Example 1:

As shown in Figures 1 and 2, an automobile decoration part with a coating carrier 11 and a seamlessly integrated lidar 2 mainly includes: a mounting frame 3, a lidar 2 and a filter decoration body 1.

The filter ornament body 1 is disposed on the mounting frame 3 and is fixedly connected to the mounting frame 3. A structural glue is provided between the mounting frame 3 and the filter ornament body 1, and the filter ornament is attached to the frame through the structural glue. The main body 1 is bonded and fixed on the mounting frame 3 . The filter decoration body 1 is located outside the mounting frame 3, and the lidar 2 is located inside the mounting frame 3; wherein, the filter decoration body 1 has a structure directly opposite the lidar 2. The radar window area 15 is invisible when viewed from the outside of the filter trim body 1. The main function of the radar window area 15 is to allow light of a preset band to pass through. The lidar 2 plays its role, and the field of view boundary line H of the lidar 2 is within the radar window area 15, ensuring that the laser transmittance emitted by the lidar 2 is high and the loss of receiving the reflected laser is small. The filter ornament body 1 includes a main body 10 and a coating carrier 11 that is integrally arranged or fixedly connected to the main body 10. This embodiment only introduces in detail the integral insert molding of the main body 10 and the coating carrier 11, and The coating carrier 11 is located at the radar window area 15. The coating carrier 11 is provided with a hardening layer 12 and an antireflection layer 13. The filter ornament body 1 is made of filter plastic. The filter plastic It can transmit the light of the preset waveband and filter the light of other wavebands to prevent the light of other wavebands from interfering with the work of the lidar 2; the light of the preset waveband can pass through the coating carrier 11 and the Hardened layer 12 and the anti-reflection layer 13.

What needs to be explained is that the filter plastic can transmit light of the preset band, which means that the light transmittance of the filter plastic at the preset value of the wave band must reach above the preset percentage to ensure that it can transmit most of the light. However, for example, it is required that more than 95% of the light in the preset band can be transmitted. Considering the actual situation, the light in the preset band generally cannot reach 100%. The filter plastic is required to also filter light in other bands, which means that for light whose band is not within the preset value, it can transmit less than the specified percentage. For example, for light whose band is not within the preset value, the filter The amount of light plastic allows to pass through is less than 5%. Considering the actual situation, it is difficult for light filter plastic to intercept 100% of light in other bands.

The filter plastic is filter PC or filter PMMA. Compared with ordinary PC or PMMA, filter PC and filter PMMA have a filtering effect, which is equivalent to the function of a filter layer, which can provide light in a preset band. Pass through and filter light in other bands. The preset band of light can be, but is not limited to, light with a band of 905±20 nanometers or 1350±20 nanometers. For example: in the laser emitted by the lidar 2, the light with a band of 905±20 nanometers or 1350±20 nanometers is sequentially emitted from From the inside to the outside, it passes through the anti-reflection layer 13, the hardened layer 12, the coating carrier 11 and the main body 10, and propagates outward. When it reaches the target object, the light is reflected back and passes through the main body 10, the coating carrier 11 and the hardened layer in sequence from the outside to the inside. 12 and anti-reflection layer 13, the laser radar 2 receives the reflected light and obtains the information of the target object.

Among them, the area of the coating carrier 11 is greater than or equal to the area of the radar window area 15, and the loss of light is small. Specifically, the material of the coating carrier 11 is transparent PC or transparent PMMA or filter PC or filter PMMA. , in this embodiment, since the filter ornament body 1 itself has a light filtering effect, the coating carrier 11 is no longer required to have a light filtering effect. The coating carrier 11 can be made of filter plastic or Made of transparent plastic, there are no special requirements for it and the material is simple.

In this embodiment, since the filter ornament body 1 itself is made of a filter plastic material with a light filtering effect, it can transmit light of the preset waveband and filter light of other wavebands, so there is no need for An additional filter layer is provided on the main body 1 of the filter decoration; and since the filter plastic material itself is generally opaque, electronic components such as lidar 2 and other electronic components inside the main body 1 of the filter decoration cannot be seen through the filter decoration from the outside. , the filter ornament body 1 itself has a blocking effect, no additional blocking coating is needed, and no obvious boundaries can be seen, the overall consistency is good, and the appearance is high.

As shown in Figures 1 to 3, the hardened layer 12 on the coating carrier 11 is used to enhance the hardness of the coating carrier 11. If the anti-reflection layer 13 is directly plated on the coating carrier 11, due to the general coating carrier 11 The hardness of the material is not enough to ensure the stability of the anti-reflection layer 13. However, if a hardened layer 12 is added to the coating carrier 11, the hardness of the coating carrier 11 can be increased to ensure good adhesion stability when the anti-reflection layer 13 is coated. , and it can meet the weather resistance requirements. Therefore, after the anti-reflection layer 13 is plated on the hardened layer 12, the hardened layer can also be used to enhance the weather resistance, cracking resistance and other properties of the anti-reflective layer 13. The hardened layer 12 may be, but is not limited to, HC, and the specific process may be spray coating or dip coating of the hardened layer 12. After adding a layer of hardened layer 12 to the coating carrier 11, a layer of anti-reflection layer 13 can be plated on it to improve the transmittance of light in the target band. Specifically, the anti-reflection layer 13 can use vacuum coating technology. The anti-reflection layer 13 is used to increase the transmittance of light in the preset wavelength band.

In this embodiment, after the hardened layer 12 and the anti-reflection layer 13 are attached to the coating carrier 11, the coating carrier 11 and the main body 10 are integrally insert-molded. During molding, the fixation between the coating carrier 11 and the main body 10 is reliable and will not cause looseness. However, it is necessary to provide a corresponding structure for positioning and fixing the coating carrier 11 on the mold of the main body 10, and this implementation The coating carrier 11 in the example is a small-sized plate structure without redundant complex structures. It is also very simple to set up corresponding positioning and fixing structures on the mold used to form the body, thus avoiding complicating the structure of the mold used to form the body.

In the actual manufacturing and use process, in order to reduce the difficulty of the coating process, this embodiment adds a coating carrier 11 to provide a carrier for various coatings. First, the coating carrier 11 is covered with the hardened layer 12, and then the hardened layer 12 is covered. The heating layer 14, anti-reflection layer 13 and other layers are coated, and finally the coated coated carrier 11 is integrated with the main body 10 through insert injection molding, or is fixed to the main body 10 through adhesive bonding to form a filter decoration. The component body 1 avoids the small-area coating operation on the large-area filter trim body 1, and can effectively improve the qualification rate of automobile trim parts, because the small-area coating operation is performed on the large-area filter trim body 1. When coating, it is easy to cause unreliable film adhesion, low yield, and high cost. It is also necessary to shield other areas on the filter ornament body 1 that are not to be coated. Coating on a small-sized coating carrier 11 can effectively improve the molding quality and improve the pass rate. Moreover, when the coating carrier 11 is not insert-molded or bonded, it is independent of the filter trim body 1 and is easy to coat.

As shown in Figures 9 and 10, another way is that in the actual manufacturing and use process, in order to reduce the difficulty of the coating process, this embodiment adds a coating carrier 11 to provide a carrier for various coatings. Here, the coating carrier 11 The material includes a heating material 111, and the heating material 111 is one of carbon nanotubes, carbon nanorods, nanosilver wires, metal heating wires or conductive heating ink. Here, carbon nanotubes and carbon nanorods can be formed on the coating carrier 11 by deposition or coating. The conductive heating ink is printed on the coating carrier 11. The metal heating wire is formed on the coating carrier 11 by hot melting. The nano silver wire is The coating is formed on the coating carrier 11, and the heating material 111 can be formed on the front or back of the coating carrier 11, so that the coating carrier 11 itself can be heated, and the heating layer can be omitted. After the coating carrier 11 is covered with the hardened layer 12 , and then add coatings of each layer such as the anti-reflection layer 13 to the hardened layer. Finally, the coating carrier 11 containing the heating material 111 is integrated with the main body 10 through insert injection molding, or is fixed to the main body 10 through adhesive bonding to form The filter trim body 1 avoids the small-area coating operation on the large-area filter trim body 1, and can effectively improve the qualification rate of automobile trims, because on the large-area filter trim body 1 When coating a small area, it is easy to cause unreliable film adhesion, low yield, and high cost. It is also necessary to shield other areas on the filter ornament body 1 that are not to be coated. Coating on a small-sized coating carrier 11 can effectively improve the molding quality and improve the pass rate. Moreover, when the coating carrier 11 is not insert-molded or bonded, it is independent of the filter trim body 1 and is easy to coat.

Among them, the lidar 2 is fixedly connected to the mounting frame 3, and there is no direct connection relationship between the lidar 2 and the filter trim body 1. Instead, the structures for fixing the lidar 2 are arranged in conjunction with the filter. The trim body 1 is installed separately on the mounting frame 3 . Specifically, the mounting frame 3 is provided with a transverse support plate 30, the transverse support plate 30 is provided with a through hole 301, the laser radar 2 is supported on the transverse support plate 30, and the laser radar 2 is provided with a threaded hole 20 corresponding to the through hole 301, and an adjustable screw 21 passes through the through hole 301 and is threadedly connected in the threaded hole 20. The adjustable screw 21 can absorb the laser radar 2 and the lateral support. The Z-direction installation error of the plate 30 is called the adjustable screw 21. In addition to the support of the transverse support plate 30, the upper and lower ends of the lidar 2 are also fixedly connected to the installation frame 3 through fixing screws. The heavier lidar 2 is supported by the transverse support plate 30 to prevent the lidar 2 from forming a cantilever beam. structure to ensure that the mounting frame 3 can provide sufficient support strength to ensure that the lidar 2 will not loosen or fall when the car is driving on various harsh road conditions; and the filter trim body 1 itself has a simple structure and is easy to form. .

Example 2:

As shown in Figures 4 to 6, the difference between this embodiment and Embodiment 1 is that in Embodiment 1, the coating carrier 11 and the main body 10 are realized by integral insert injection molding, while in this embodiment The coating carrier 11 is fixed on the main body 10 through optical adhesive. That is, after the hardened layer 12 and the anti-reflection layer 13 are attached to the coating carrier 11, the coating carrier 11 is fixed on the main body 10 through optical glue. Insert injection molding will add a structure for positioning and fixing the coating carrier 11 to the mold used to form the main body 10, while adhesive fixing does not require adding corresponding structures to the molding mold. It should be explained that the optical glue layer 16 can be, but is not limited to, OCR/OCA glue. The optical glue layer 16 has the function of canceling the interface between the coating carrier 11 and the filter ornament body 1 after surface treatment such as coating, so that the light filtering The multi-layer structure of the radar window area 15 of the trim body 1 is integrated, thereby eliminating the impact of laser transmission attenuation caused by the multi-layer structure.

After adding the heating layer 14, the automobile decoration part in Embodiment 1 can have defrosting and defogging functions.

Embodiment 4:

As shown in Figure 8, this embodiment is based on the second embodiment, adding a heating layer 14. Its arrangement is the same as that of the third embodiment, and will not be described in detail here. In the same way, after adding the heating layer 14, you can The automobile decoration part in the second embodiment is provided with defrosting and defogging functions.
