Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to an automotive trim component with a transparent, seamless integrated lidar and its manufacturing method. Background Technology

[0002] When a lidar is working, it emits a laser beam. After the laser beam is reflected by the target object, the lidar receives the reflected laser beam and analyzes relevant information about the target object, such as distance, altitude, and attitude. LiDAR has numerous applications in automobiles, especially with the promotion of autonomous driving, leading to its increasingly widespread use in vehicles. LiDAR can be integrated into various automotive components such as sunroofs, grilles and bumpers, headlights, fenders, side mirrors, and tailgates.

[0003] The initial method for integrating LiDAR into automotive trim is generally to create an opening in the trim body and place the LiDAR in a corresponding position. However, this method results in gaps and surface differences between the LiDAR and the surrounding trim, affecting the aesthetics of the automotive trim.

[0004] To address the aforementioned gap and surface defects, a method for seamlessly integrating LiDAR into automotive trim has emerged on the market: eliminating the need for openings in the trim. For example, patent number "CN114655126A" discloses a seamlessly integrated LiDAR automotive trim and its adhesive bonding process. However, this structure and molding process cannot be used if the main body is made of a transparent material. Furthermore, while this automotive trim achieves seamless LiDAR integration, the filter layer and frame are made as a single piece, then fixed to the trim body via insert injection molding or adhesive bonding, with the LiDAR directly mounted on top. If the filter layer is a diaphragm type, insert injection molding is not feasible because the diaphragm is affected by the high temperature of the mold, impacting its filtering effect. If the filter layer is a filter plate type, the LiDAR becomes too heavy, failing to provide sufficient support strength, and resulting in a complex mold structure for the trim body during insert injection molding. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by the present invention is to propose an automotive trim part of a transparent seamless integrated lidar with convenient manufacturing, low cost and neat radar window boundary, and the same manufacturing method.

[0006] The technical solution adopted by this invention to solve its technical problem is to propose an automotive trim component with a transparent, seamlessly integrated lidar, comprising:

[0007] Connected decorative body, mounting frame and lidar;

[0008] The decorative element body is disposed on the side of the mounting frame away from the lidar and connected to the mounting frame. The decorative element body includes a main body and a shielding coating covering the main body. The shielding coating is located on the side of the main body closer to the mounting frame. The main body is made of transparent plastic. The decorative element body has a lidar window area facing the lidar. A filter layer is provided on the decorative element body along the lidar window area. The filter layer allows light of a preset wavelength to pass through and filters light of other wavelengths.

[0009] Furthermore, the coverage area of ​​the shielding coating extends beyond the boundary line of the radar window area from the outside in.

[0010] Furthermore, a hardening layer is provided on the filter layer to enhance the hardness of the filter layer; an anti-reflection layer is provided on the hardening layer to increase the transmittance of the preset wavelength light.

[0011] The filter layer allows light in the 905±20 nm and / or 1350±20 nm bands to pass through, and filters light in other bands.

[0012] Furthermore, a medium layer is provided on the hardened layer, and a preset pattern is provided on the medium layer to present the preset pattern on the body of the ornament.

[0013] Furthermore, the filter layer, the hardening layer, the antireflective layer, and the dielectric layer are combined into an intermediate component, which is then integrally injection molded with the main body.

[0014] Alternatively, the filter layer, the hardening layer, the antireflective layer, and the dielectric layer can be combined into an intermediate component and then bonded to the main body with optical adhesive.

[0015] Furthermore, the shielding coating covers the boundary line of the intermediate component, and the lidar does not cover the shielding coating within the field of view of the filter layer.

[0016] Furthermore, a heating layer is also provided on the hardened layer, and the filter layer, the hardened layer, the dielectric layer, the heating layer and the antireflection layer are combined to form the intermediate component.

[0017] Furthermore, both the decorative element body and the lidar are fixedly connected to the mounting frame;

[0018] The mounting frame is provided with an upper mounting part and a lower mounting part, and the lidar is fixedly connected to both the upper mounting part and the lower mounting part; a support plate is provided on the mounting frame along the bottom of the lidar, and the lidar is supported on the support plate and fixedly connected to the support plate.

[0019] Furthermore, both the upper mounting part and the lower mounting part are fixedly connected to the lidar by screws, clips, or welding, and a sealing strip is provided between the lidar and the mounting frame;

[0020] Alternatively, both the upper mounting part and the lower mounting part can be fixedly connected to the lidar by adhesive.

[0021] The technical solution adopted by this invention to solve its technical problem is to propose a manufacturing method for an automotive trim component with a transparent, seamlessly integrated lidar. The automotive trim component includes: a connected trim body, a mounting frame, and a lidar; the trim body is disposed on the mounting frame on the side away from the lidar and connected to the mounting frame; the trim body includes a main body and a shielding coating covering the main body, the shielding coating being located on the side of the main body closer to the mounting frame; the main body is made of transparent plastic; the trim body has a lidar window area facing the lidar; a filter layer is provided along the lidar window area on the trim body; a hardening layer is provided on the filter layer; a dielectric layer and an anti-reflection layer are provided on the hardening layer; the filter layer allows light of a preset wavelength to pass through and filters light of other wavelengths; the manufacturing method includes the following steps:

[0022] The hardened layer is sprayed or dipped onto the filter layer;

[0023] The dielectric layer and the antireflective layer are deposited on the hardened layer and combined to form an intermediate component, and the dielectric layer is provided with a preset pattern;

[0024] The intermediate component is placed as an insert into the molding mold of the main body for insert injection molding, or the intermediate component is bonded to the main body by optical adhesive;

[0025] The shielding coating is sprayed or printed on the inner surface of the main body, and the shielding coating covers the boundary line of the intermediate component. The lidar does not cover the shielding coating within the field of view of the filter layer, thus forming the body of the decorative part.

[0026] The laser radar is fixedly mounted on the mounting frame, and the decorative part body is fixedly connected to the mounting frame.

[0027] Compared with the prior art, the present invention has at least the following beneficial effects:

[0028] In this invention, the main body of the trim piece is made of transparent plastic. First, a filter layer, a hardening layer, a dielectric layer, and an anti-reflective layer are formed into an intermediate component, which is then integrally injection molded or glued to the main body. The filter layer can be either a plastic filter plate or a plastic filter film. Furthermore, by incorporating this intermediate component onto the inner wall of the main body, a masking coating is applied. This masking coating can be any desired color, such as blue, black, or silver. During this painting process, strict masking of the main body or the intermediate component is not required. Even if overspray or runs occur on the intermediate component, only the boundary line of the intermediate component is visible from the outer side of the trim piece, resulting in a neat boundary line. Overspray defects are not visible, thus not affecting the overall aesthetics of the automotive trim piece. Because the masked boundary is invisible, the painting difficulty is effectively reduced, and the manufacturing cost of the automotive trim piece is low.

[0029] In this invention, the mounting frame is made as a separate part, rather than being integrated with the trim body and the filter layer. This allows for a more complex structure to ensure better support strength for the relatively heavy lidar. A support plate is provided along the bottom of the lidar on the mounting frame, supporting the overall weight of the lidar and preventing the formation of a cantilever beam structure. This ensures that the lidar will not loosen or fall off when the vehicle is driving in various harsh road conditions. Furthermore, the trim body itself has a simple structure and is easy to mold.

[0044] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0045] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0046] Furthermore, in this invention, descriptions involving terms such as "first," "second," and "a" are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0047] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0048] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0049] The automotive trim parts of this invention can be applied to areas such as front and rear sunroofs, grilles and bumpers, headlights and taillights, mudguards, rearview mirrors and tailgates.

[0050] Example 1:

[0051] like Figures 1-3 As shown, an automotive trim piece with a transparent, seamlessly integrated lidar 2 mainly includes: a mounting frame 1, a lidar 2, and a trim piece body 3.

[0052] The lidar 2 is mounted on and fixedly connected to the mounting frame 1. The mounting frame 1 has an upper mounting portion 10 and a lower mounting portion 11, and the lidar 2 is fixedly connected to both. The mounting frame 1 is a single injection-molded part, and both the upper mounting portion 10 and the lower mounting portion 11 have positioning posts that mate with positioning holes on the lidar 2, ensuring accurate installation. A support plate 12 is provided along the bottom of the lidar 2 on the mounting frame 1. The lidar 2 is supported on and fixedly connected to the support plate 12, specifically by adjustable screws, which can absorb Z-axis installation errors of the lidar 2. The support plate 12 supports the relatively heavy lidar 2, preventing a cantilever beam structure and ensuring sufficient support strength from the mounting frame 1.

[0053] Specifically, there are several ways to fix the upper mounting part 10 and the lower mounting part 11 to the lidar 2: Preferably, both the upper mounting part 10 and the lower mounting part 11 are provided with threaded holes, and screws pass through the lidar 2 and are threaded into the threaded holes, so that the lidar 2 is detachably fixed to the mounting frame 1. Alternatively, it can be fixed by snap-fit ​​or by welding. In all three fixing methods, to ensure that the lidar 2 forms a sealed space and thus protects the internal components from external influences, a sealing strip 13 needs to be provided between the lidar 2 and the mounting frame 1. Furthermore, to eliminate the need for the sealing strip 13, the upper mounting part 10 and the lower mounting part 11 are fixed to the lidar 2 with adhesive. Adhesive fixing itself provides a sealing effect, so the sealing strip 13 is not required.

[0054] In this design, the mounting frame 1 is made as a separate part, rather than being integrated with the trim body 3 and the filter layer 321. This allows for a more complex structure for the mounting frame 1, ensuring better support strength to adequately support the relatively heavy lidar 2. A support plate 12 is provided along the bottom of the lidar 2 on the mounting frame 1, supporting the overall weight of the lidar 2 and preventing the formation of a cantilever beam structure. This ensures that the lidar 2 will not loosen or fall off under various harsh road conditions. Furthermore, the trim body 3 itself has a simple structure and is easy to mold.

[0055] The trim body 3 is disposed on the side of the mounting frame 1 away from the lidar 2 and is connected to the mounting frame 1. The trim body 3 includes a main body 30 and a shielding coating 31 covering the main body 30. The shielding coating 31 is located on the side of the main body 30 closer to the mounting frame 1. The main body 30 is made of transparent plastic. Because the main body 30 is made of transparent plastic, if it is not shielded, the internal structure of the trim can be seen through the main body 30 when it is installed in the corresponding position on the car, affecting its aesthetics. Therefore, a shielding coating 31 needs to be provided on the inner wall of the main body 30. This shielding coating 31 can play a role in concealing unsightly features. The coverage area of ​​the shielding coating 31 extends beyond the boundary line 311 of the lidar window area 32 from the outside in. If it does not exceed the boundary line 311, light leakage or transparency may occur, affecting the aesthetics of the trim. The decorative element body 3 has a radar window area 32 facing the lidar 2. The main function of the radar window area 32 is to allow light of a preset wavelength to pass through, so that the lidar 2 can function. The radar's field of view boundary line 311 is within the radar window area 32, ensuring high transmittance of the laser emitted by the lidar 2 and low loss of the received reflected laser light. Figure 1 and Figure 2 The dotted line shown in the figure represents the field-of-view boundary line 311 of the lidar 2. The lidar 2 does not cover the shielding coating 31 within the field of view of the filter layer 321, so as not to affect the normal operation of the lidar 2.

[0056] A filter layer 321 is provided on the main body 3 of the decorative component along the radar window area 32. The filter layer 321 allows light of a preset wavelength to pass through while filtering light of other wavelengths. It should be explained that the function of the filter layer 321 is to ensure the passage of light of the preset wavelength while filtering light of other wavelengths to prevent light of other wavelengths from interfering with the normal operation of the lidar 2. The filter layer 321 can be a filter plastic film or a filter plastic sheet, and its material can specifically be filter PC or filter PMMA. The preset wavelength can be, but is not limited to, light with a wavelength range of 905±20 nanometers or 1350±20 nanometers. Light within this preset wavelength range can pass through the filter layer 321, while light of other wavelengths will be filtered by the filter layer 321. Considering practical usage and potential losses, the filter layer 321 is generally required to have a transmittance of over 90% for light in the 905±20 nm or 1350±20 nm wavelength range, while ensuring a transmittance of less than 5% for other wavelength ranges. This is necessary to allow light in the preset wavelength range to pass through while filtering other wavelength ranges. This is because it can only guarantee that most of the light in the preset wavelength range passes through; achieving 100% transmission is practically very difficult. Similarly, for light outside the preset wavelength range, it can only guarantee that most of it does not pass through; achieving 100% interception is also difficult to achieve.

[0057] Specifically, the filter layer 321 is provided with a hardening layer 322, which is used to enhance the hardness of the filter layer 321; the hardening layer 322 is provided with an antireflection layer 323, which is used to increase the transmittance of the preset wavelength light. When an antireflection layer 323 is directly deposited on the filter layer 321, the hardness of the filter layer 321 cannot meet the coating hardness requirements. Therefore, a hardening layer 322 needs to be added to the filter layer 321 to give the filter layer 321 sufficient hardness so that it can meet the weather resistance requirements. The hardening layer 322 can be, but is not limited to, HC. Specifically, the hardening layer 322 can be sprayed or dip-coated. After adding a hardening layer 322 to the filter layer 321, an antireflection layer 323 can be deposited on it to improve the transmittance of the filter layer 321 to the target wavelength light. Specifically, vacuum coating technology can be used.

[0058] like Figures 4-5 As shown, a medium layer 324 is also provided on the hardened layer 322, and a preset pattern 326 is provided on the medium layer 324 to present the preset pattern 326 on the trim body 3. The preset pattern 326 can be a car logo, text, or other logo. Figure 5In the diagram, the dashed box indicates the radar window boundary line 311. The preset pattern 326 outside the radar window boundary can be set to a 3D effect, for example, by engraving or etching the preset pattern 326 on the inner surface of the decorative body 3. However, the preset pattern 326 within the radar window boundary line 311 cannot be set to a 3D effect, otherwise it would increase the probability of laser reflection or refraction, thus affecting the operation of the lidar 2. Therefore, the preset pattern 326 in this area can only be a planar preset pattern 326.

[0059] The process for the dielectric layer 324 can be the same as that for AR coating. After depositing the dielectric layer 324, the transmittance of the substrate to light of the preset wavelength will not decrease, or will decrease within an acceptable range. Similarly, the hardness of the filter layer 321 is insufficient to deposit the dielectric layer 324, so the dielectric layer 324 also needs to be deposited on the hardening layer 322 after adding the hardening layer 322. The dielectric layer 324 can display the desired color, such as silver, blue, black, etc., on the transparent body 30. Since the dielectric layer 324 is on one side of the filter layer 321 and the antireflective layer 323 is on the other side of the filter layer 321, when adding the hardening layer 322 on the filter layer 321, both sides of the filter layer 321 need to be added.

[0060] like Figures 1-5 As shown, the filter layer 321, the hardening layer 322, the antireflective layer 323, and the dielectric layer 324 are combined into an intermediate component, which is then integrally injection molded with the main body 30. In this embodiment, it is called an intermediate component because it is mainly set up to simplify the molding process of the decorative body 3. Ultimately, the intermediate component becomes part of the decorative body 3, and the injection molding ensures reliable connection between each layer and the main body 30. Furthermore, the shielding coating 31 covers the boundary line 311 of the intermediate component, ensuring that the decorative body 3 does not leak light and forms a neat boundary when viewed from the outside.

[0061] Example 2:

[0062] like Figure 6 As shown, the difference between this embodiment and Embodiment 1 lies in the fact that a heating layer is also provided on the hardened layer 322. The filter layer 321, the hardened layer 322, the dielectric layer 324, the heating layer, and the anti-reflection layer 323 are combined to form the intermediate component. The provision of this heating layer enables the automotive trim to have defrosting and defogging functions, and the heating layer can be located between the hardened layer 322 and the anti-reflection layer 323.

[0063] Example 3:

[0064] like Figures 7-9As shown, the difference between this embodiment and Embodiment 1 lies in the fact that in Embodiment 1, the intermediate component is integrally molded with the main body 30 using an insert molding method, while in this embodiment, the intermediate component is glued to the main body 30 using an optical adhesive layer. This is because insert molding complicates the structure of the mold used to form the main body 30, while adhesive bonding eliminates the need to add corresponding structures to the mold. That is, after the filter layer 321, the hardening layer 322, the antireflective layer 323, and the dielectric layer 324 are combined into an intermediate component, they are bonded to the main body 30 using optical adhesive.

[0065] It should be explained that the optical adhesive layer can be, but is not limited to, OCR / OCA adhesive. The optical adhesive layer has the function of eliminating the interface between the filter layer 321 and the decorative body 3 after surface treatment such as coating, so that the multi-layer structure of the window area of ​​the decorative body 3 is integrated, thereby eliminating the influence of laser transmission attenuation caused by the multi-layer structure.

[0066] Example 4:

[0067] like Figure 10 As shown, the difference between this embodiment and Embodiment 3 lies in the fact that a heating layer is also provided on the hardened layer 322. The filter layer 321, the hardened layer 322, the dielectric layer 324, the heating layer, and the antireflective layer 323 are combined to form the intermediate component. The provision of this heating layer enables the automotive trim in Embodiment 3 to have defrosting and defogging functions, and this heating layer can be located between the hardened layer 322 and the antireflective layer 323.

[0068] Example 5:

[0069] This embodiment describes a method for manufacturing an automotive trim component, specifically a transparent, seamlessly integrated lidar 2 (body 30). This method can be referenced from [the relevant documentation / reference]. Figure 3 and Figure 9 The automotive trim component includes: a mounting frame 1, a lidar sensor 2, and a trim component body 3. The lidar sensor 2 is mounted on the mounting frame 1 and fixedly connected to it. The trim component body 3 is located on the mounting frame 1 on the side away from the lidar sensor 2 and is connected to the mounting frame 1. The trim component body 3 includes a main body 30 and a shielding coating 31 covering the main body 30. The shielding coating 31 is located on the main body 30 on the side closer to the mounting frame 1. The main body 30 is made of transparent plastic. The trim component body 3 has a radar window area 32 facing the lidar sensor 2. A filter layer 321 is provided on the trim component body 3 along the radar window area 32. A hardening layer 322 is provided on the filter layer 321. A dielectric layer 324 and an anti-reflection layer 323 are provided on the hardening layer 322. The filter layer 321 allows light of a preset wavelength to pass through and filters light of other wavelengths. The manufacturing method includes the following steps:

[0070] The hardened layer 322 is sprayed or dipped onto both sides of the filter layer 321 to give the filter layer 321 sufficient strength to allow other layers to be deposited on it.

[0071] The dielectric layer 324 and the antireflective layer 323 are deposited on the hardened layer 322 to form an intermediate component, and the dielectric layer 324 is provided with a preset pattern 326; when there is also a heating layer, the heating layer also needs to be deposited in this step of the process when forming the intermediate component.

[0072] The intermediate component is placed as an insert into the molding mold of the main body for insert injection molding, or the intermediate component is bonded to the main body 30 by optical adhesive 325.

[0073] The shielding coating 31 is sprayed or printed on the inner surface of the main body 30, and the shielding coating 31 covers the boundary line 311 of the intermediate component. The lidar 2 does not cover the shielding coating 31 within the field of view of the filter layer 321, thus forming the decorative body 3.

[0074] The lidar 2 is fixedly mounted on the mounting frame 1, and the trim body 3 is fixedly connected to the mounting frame 1 to form a transparent, seamless integrated lidar 2 automotive trim body 30.

[0075] In summary, in this invention, the main body 30 of the decorative element body 3 is made of transparent plastic. First, the filter layer 321, hardening layer 322, dielectric layer 324, and antireflective layer 323 are formed into an intermediate component, which is then integrally injection molded or glued to the main body 30. The filter layer 321 can be either a plastic filter plate or a plastic filter film. Furthermore, by setting this intermediate component, after integrating the intermediate component onto the inner wall of the main body 30, a masking coating 31 is applied. This masking coating 31 can be blue or black. This painting process can use any color, such as silver, without requiring strict masking of the main body 30 or intermediate parts. Even if overspray or runs occur on the intermediate parts, only the boundary line 311 of the intermediate parts can be seen from the outer side of the trim body 3, resulting in a neat boundary line 311. Overspray defects on the intermediate parts are not visible, thus not affecting the overall aesthetics of the automotive trim. Because the boundary appearance is not visible, the painting difficulty is also effectively reduced, and the manufacturing cost of automotive trim is low.
