Abstract
Description
TECHNICAL FIELD
[0001] The present invention relates to a radome for covering a radar of a vehicle and to a method for producing said radome. BACKGROUND
[0002] Modern motor vehicles have a plurality of sensors which record, process and forward information about the vehicle's surroundings to a control unit. In addition to optical systems such as cameras and laser radars (light detection and ranging) and acoustic systems such as short-range ultrasound, for example in the case of parking sensors, radar sensors (radar = radio detection and ranging) are installed in particular in the front and rear regions. Radar sensors emit modulated electromagnetic waves, the wavelength of which is approximately 24 GHz in the automotive sector and is in the 77 to 79 GHz frequency band. The radar signals are reflected by other vehicles, pedestrians, cyclists or objects at the edge of the road, and the reflected signals are received by the transmitting sensor. The latter calculates a list of recognized destinations with directional and distance information from the reflections and transmits it to the connected control unit. In this way, driving assistance systems such as adaptive speed control (adaptive cruise control, ACC), emergency brake assist systems, lane assist systems or automatic driving functions can be assisted.
[0003] The radar signals are usually emitted by an antenna array. The individual antennas of the array are driven with different amplitudes and phases so that the radar signals leave the sensor in a preferred direction and the reflected signals are received in a preferred direction as well. By time control of the amplitudes and phases, a defined angular range in front of the vehicle, and possibly behind and to the side, can be scanned.
[0004] In order to protect the radar sensors, but also for reasons of the optical systems, the radar sensors in motor vehicles are often covered by a radome or are installed behind vehicle components that exist anyway, such as bumpers. A radome is a covering which on the one hand provides the necessary protection against dust, dirt, water, falling rocks, etc. for the radar sensors and on the other hand allows the radar radiation to be transmitted as unhindered as possible. This relates both to the overall amplitude attenuation and to the angular dependence of the attenuation. On the one hand, due to the fact that the radar beam passes through the radome twice, in particular during the emission and reception of the reflected signals, it is desirable to attenuate the overall amplitude as little as possible. On the other hand, the angular dependence of the attenuation must remain below a low tolerance threshold, otherwise the direction of the radar targets can no longer be determined accurately enough. In addition, inhomogeneities in the radome can make reliable target detection impossible or lead to the generation of radar targets that do not actually exist (ghost targets). Inhomogeneities manifest themselves in local radar transmission occurring greatly, which can lead to refraction or scattering of the radar waves, similar to cracks or steps in a glass plate or air inclusions in water ice. SUMMARY
[0005] It is therefore an object of the present application to provide a radome for a motor vehicle radar which, on the one hand, has an optically attractive design and, on the other hand, is able to meet the requirements of modern radar systems in terms of radar transmission, and which is furthermore inexpensive to produce.
[0006] This object is achieved by a radome according to claim 1. Advantageous configurations are the subject of the dependent claims.
[0007] The radome according to the application is designed to cover a vehicle radar and comprises a first plastic component and a second plastic component. Furthermore, the radome comprises at least one interface formed between the first plastic component and the second plastic component, the first plastic component being connected to the second plastic component at the interface by means of injection molding. Furthermore, the radome comprises a radar region which is designed for the transmission of radar radiation from the vehicle radar, the at least one interface being arranged at least partially in the radar region.
[0008] The radome according to the application is designed to cover a vehicle radar. This means that, during normal operation of the vehicle radar, electromagnetic waves emitted by the radar pass through the radome both during emission and during reception of reflected waves, on the one hand, and that the electromagnetic waves are only impaired within the specifications of the radar or vehicle manufacturer, on the other hand. This relates both to the overall transmission and to the angle dependence. The radome is thus permitted for the intended purpose, in particular by the vehicle or radar manufacturer using it as a cover for a motor vehicle radar.
[0009] The radome according to the application also comprises a first plastic component and a second plastic component. The first plastic component and the second plastic component are thus at least segments or parts of the radome which are optically delimited from one another and comprise two different plastic components. The two plastic components meet at at least one interface. This interface thus separates the first plastic component from the second plastic component and delimits both from one another. The radome according to the application can in principle comprise a plurality of such interfaces, but at least one. For example, the first component and / or the second component can be present in a plurality of delimitable regions of the radome, resulting in a plurality of interfaces. In the case of a plurality of interfaces, the following description relating to the at least one interface applies accordingly to the other interfaces.
[0010] The at least one interface can be arranged at any desired angle with respect to a surface of the radome. For example, the interface can be at right angles to the surface or can be inclined with respect to the surface. The angle can also change in the course of the extension of the interface. The application leaves a large design scope here without negatively influencing the radar transmission of the radome.
[0011] Two plastic parts are joined at the interface. In this case, the two plastic parts are joined by injection molding. Therefore, both parts are produced by a single injection molding method and are thus connected to each other. Therefore, this is a multi-part injection molding method, or at least a two-part injection molding method. Therefore, adhesives, tackifiers, etc., which are harmful to radar transmission, can be omitted at the interface. The connection between the parts is entirely based on the chemical bonding force generated by the plastic parts themselves.
[0012] Furthermore, the radome includes a radar area designed to transmit radar radiation from the vehicle's radar. As mentioned above, all specifications from the vehicle or radar manufacturer regarding electromagnetic radar signal transmission are complied with within the radar area. This means that, on the one hand, the overall transmission is not substantially impaired, and on the other hand, the angular dependence of the transmission is not substantially distorted. Therefore, the radar area is crucial for the operation of the radar covered by the radome. Preferably, the radar area is a portion of the radome. Thus, for example, fastening devices, such as screw holes, clamps, springs, etc., can be located outside the radar area to secure the radome to the vehicle, in front of the radar.
[0013] Furthermore, according to the claim, at least one interface is at least partially disposed within the radar region. The inventors have recognized that, in this manner, an optically attractive radome can be designed, for example, one that is difficult to detect. Although the interface between the two plastic components extends within the radar region, non-uniformity at the interface can be avoided due to the injection molding method used to connect the two plastic components. Furthermore, additional connecting components, such as adhesives, tackifiers, etc., which themselves can cause non-uniformity and may have different radar transmissions compared to the plastic components, can be eliminated.
[0014] Although the interface between the two plastic components extends within the radar area, radar transmission is therefore not substantially impaired. This allows for design freedom in the radome, enabling the lamination of radome functions, such as those present as vehicle components in any situation. For example, the injection molding technology used allows for the production of both inexpensive and optically attractive products compared to films as design elements.
[0015] The first plastic component can be chemically bonded to the second plastic component at at least one interface. For example, the chemical bonding may be the result of injection molding. Due to the purely chemical bonding, adhesives, tackifiers, etc., can be eliminated.
[0016] The first plastic component may include a first type of colored pigment, while the second plastic component includes a second type of colored pigment, distinct from the first type. Preferably, the first plastic component does not include the second type of colored pigment, and the second plastic component does not include the first type of colored pigment. In this way, the two plastic components can be optically distinguishable from each other, and the radome can have an optically attractive design. For example, the first type of colored pigment may be white, and the second type of colored pigment may be black. Alternatively, one plastic component may contain colored pigment, while the other does not.
[0017] In one embodiment of the invention, the first type of colored pigment and the second type of colored pigment are not metallic-based colored pigments. Metals can be detrimental to radar transmission, causing overall attenuation and / or undesirable directional deviations. By omitting metallic pigments, radar transmission is not substantially impaired.
[0018] The radome can have a substantially constant thickness within the radar region. Therefore, the angular dependence of radar transmission is minimized.
[0019] The radome may include a third plastic component and at least one second interface formed between the third plastic component and the first plastic component, said at least one second interface being at least partially disposed in the radar region; it may also include at least one third interface formed between the third plastic component and the second plastic component, said at least one third interface being at least partially disposed in the radar region. In principle, any desired number of plastic components can be used within the scope of this invention, but at least two. The third component significantly expands the design range of the radome. These three components can be connected to each other in a single three-component injection molding method.
[0020] The third plastic component can cover the first and second plastic components, forming a covering layer for the radome. In this way, on the one hand, the radome itself can be provided with a protective layer, and on the other hand, depending on the design of the radome, the third component can serve as a carrier layer for the first and second plastic components on the rear side (i.e., the side facing the radar).
[0021] The third plastic component can be transparent. This greatly expands the range of optical designs because the first and second components function as if cast into the transparent cover. On the other hand, the transparent cover acts as an end cap, preventing dirt from adhering to the structure formed by the first and second plastic components. Finally, for optical reasons, the first and second components can be configured to have different thicknesses, which are compensated for by the transparent cover, resulting in a substantially constant overall thickness of the radome within the radar area.
[0022] The covering layer can be 1 to 3 mm thick. The inventors have realized that this area is optimal for protective function, while also producing a positive optical impression.
[0023] At least one plastic component may be polymethyl methacrylate (PMMA). PMMA is a non-exclusive example of a plastic suitable for the scope of this invention, is easily processed in injection molding methods, and meets the requirements for radar transmission. This invention is not limited to PMMA. Other plastics are also possible.
[0024] In each case, each part of the interface must be free of gas inclusions within the radar area. Gas inclusions can cause inhomogeneities and may render the radome unusable. Gas inclusions can be effectively avoided by using a multi-part injection molding method to join the plastic components.
[0025] The radome may include at least one injection point located outside the radar zone. Injection points are necessary to allow the plastic forming the plastic part to be injected into the injection cavity. These are typically openings in the cavity or its counterpart in a closed cavity. These openings typically leave tactile and visible features in the finished plastic part, particularly the so-called injection points. Because these are located outside the radar zone, the influence of the injection points on the emitted radar waves is avoided.
[0026] The radome can be a logo design. A logo design is understood to include decoration, emblem (e.g., a vehicle manufacturer's logo), type name, etc. In particular, vehicle manufacturer logos are often mounted on the front area of a vehicle, such as above, below, or above the radiator grille. According to the invention, due to the use of a multi-part injection molding method, the interface between two plastic parts can be freely set, especially within the radar area, without substantially impairing radar transmission (in any case, within the specifications of the vehicle manufacturer or radar manufacturer). In this way, not only can the vehicle manufacturer's logo be reproduced, but it also functions as a radome, although the latter function is generally not considered. The radar can be hidden behind the vehicle manufacturer's logo. Such a logo with radome functionality can be produced inexpensively and optically attractively using a multi-part injection molding method.
[0027] Another aspect of the present invention relates to a method for producing a radome as described herein, the method comprising the following steps: A first plastic component is injected into a first cavity; the injected plastic component is transferred into a second cavity; a second plastic component is injected into the second cavity, thereby forming an interface between the first plastic component and the second plastic component.
[0028] Preferably, these steps are performed in the order described above.
[0029] All statements regarding the radome according to the invention, especially its advantages, apply accordingly to the method of production. Attached Figure Description

[0035] The following describes only some feasible embodiments of the present invention in detail. However, the present invention is not limited thereto, and many other embodiments are conceived without departing from the scope of the invention. The presented embodiments can be modified in various ways, and can be combined with each other as long as these embodiments are compatible, and certain features can be omitted as long as certain features appear unnecessary. In particular, the disclosed embodiments can be modified by combining certain features of one embodiment with one or more features of another embodiment.
[0036] Although the following embodiments are described primarily with reference to radomes, those skilled in the art will recognize that methods for producing such radomes also benefit from the features and advantages described.
[0037] In this drawing and specification, the same reference numerals denote the same elements. These drawings may not be drawn to scale, and for clarity, illustration, and convenience, the relative sizes, proportions, and representations of elements in the drawings may be exaggerated, and will differ accordingly in other embodiments of the invention.
[0038] Figure 1AA radome 10 is shown, designed to cover a vehicle radar (not shown). This radome affects the transmission of the radar beam generated by the vehicle radar. The radome 10 is mounted in front of the vehicle radar and is within the specifications of the vehicle manufacturer or radar manufacturer. Specifically, the attenuation of radar transmission and the variation in the emission angle are kept below certain limits. Therefore, the radome 10 is designed to meet its intended purpose, specifically, on the one hand, to protect the vehicle radar and optically conceal it, while allowing the vehicle radar to operate correctly during vehicle operation.
[0039] exist Figure 1A In an exemplary embodiment, the radome 10 includes a first plastic component 1, a second plastic component 2, and a third plastic component 3. The invention is not limited to the presence of three plastic components. According to the invention, the radome includes at least two plastic components. Different numbers, such as four or more plastic components, are possible.
[0040] exist Figure 1A In an exemplary embodiment, plastic components 1, 2, and 3 comprise PMMA. PMMA is a non-exhaustive example of plastics that can be used within the scope of this invention. In other embodiments, other types of plastics may be used, and different types of plastics may be used within a single radome.
[0041] In addition, the radome 10 includes at least one interface 4 formed between the first plastic component 1 and the second plastic component 2. Figure 1A The edge of the second plastic component 2 is shown, as the interface extends from the surface formed by the first plastic component 1 and the second plastic component 2 into the radome 10. Figure 1B The cross-sectional view shows the relationship with Figure 1A In the same exemplary embodiment, interface 4 is shown in cross-section within the radome 10. Interface 4 separates the first plastic component 1 from the second plastic component 2. Figure 1A In an exemplary embodiment, a single interface 4 exists between the first plastic component 1 and the second plastic component 2. In other exemplary embodiments, multiple interfaces may be formed, particularly when the plastic components form multiple mutually delimitable regions.
[0042] The first plastic component 1 is connected to the second plastic component 2 at interface 4 via injection molding. During injection molding, the plastic is plasticized (i.e., liquefied) in the injection molding unit by the injection molding machine and injected under pressure into the injection mold. For example, the injection mold is formed by corresponding counterparts of the mold and the closed mold. Within the injection mold, the material re-enters the solid state due to cooling or cross-linking reactions and is removed as a finished part after the injection mold is opened. In this case, the cavity (also called the cavity) of the mold determines the shape and surface structure of the finished part. Figure 1A and 1BThe radome 10 shown is manufactured using a multi-part injection molding method. More precisely, it is a three-part injection molding method, also known simply as the 3K injection molding method.
[0043] Due to injection molding, the first plastic component 1 and the second plastic component 2 are permanently bonded at interface 4. This is a chemical bond caused by the pressure and temperature generated during the injection molding process. In particular, this avoids gas inclusions at the interface of the plastic components, which can impair radar transmission.
[0044] exist Figure 1A and 1B In an exemplary embodiment, the second plastic component 2 is embedded within the first plastic component 1. The second plastic component 2 has an "X" shape within a circle. However, this shape is merely an example, and in other embodiments, the plastic component may include any desired shape. For example, the second plastic component 2 may have the shape of a car manufacturer's logo, or the second plastic component may be a type name.
[0045] The first plastic component 1 includes a first type of colored pigment, and the second plastic component 2 includes a second type of colored pigment. Figure 1A and 1B In an exemplary embodiment, the first plastic component 1 is black and the second plastic component 2 is white. In other exemplary embodiments, different colors will be used accordingly. In particular, these types of colored pigments are not metallic-based and therefore will not affect radar transmission or will only have a negligible effect on it.
[0046] exist Figure 1A and 1B In an exemplary embodiment, the radome 10 further includes a third plastic component 3. As previously stated, according to the invention, two plastic components are sufficient. In this exemplary embodiment, the third plastic component 3 is transparent and covers the first plastic component 1 and the second plastic component 2 as a covering layer. Since the third plastic component 3 is transparent, the first plastic component 1 and the second plastic component 2 are visible through the third plastic component 3. The covering layer 3 covers the edge of the second plastic component 2.
[0047] Additional interfaces are created between the plastic components. Specifically, a second interface 5 is created between the third plastic component 3 and the first plastic component 1, and a third interface 6 is created between the second plastic component 2 and the third plastic component 3 (see...). Figure 1B and Figure 2C In other exemplary embodiments having more than three plastic parts, more interfaces may be generated accordingly, the number of which also depends on the number of non-interconnected portions of the plastic parts.
[0048] In other exemplary embodiments, the third plastic component may not be disposed on the front side of the radome, but rather on the rear side of the radome, i.e., the side facing the radar. In this case, the third plastic component can serve as a carrier layer for other plastic components. In other exemplary embodiments, a plastic layer is disposed on the front side as a covering layer, and another plastic layer is disposed on the rear side as a carrier layer.
[0049] Figure 2A , Figure 2B and Figure 2C Showing Figure 1A and Figure 1B A structural diagram of an exemplary radar dome 10. (See diagram below.) Figure 2A and Figure 2B As shown, the radome 10 also includes a radar region 7, which is designed to transmit radar radiation from the vehicle's radar. By definition, a radome includes a radar region, wherein the radome affects the transmission of the radar beam generated by the vehicle's radar, which is mounted in front of the vehicle's radar and within the specifications of the vehicle manufacturer or radar manufacturer. In particular, the attenuation of radar transmission and the variation in the emission angle within the radar region 7 are kept below certain limits. If a radar beam outside the radar region 7 passes through the radome 10, this may negatively affect the transmission.
[0050] exist Figure 2A , Figure 2B and Figure 2C In an exemplary embodiment, radar region 7 is rectangular. In other exemplary embodiments, radar region may include different shapes, such as square, elliptical, or circular. The shape may depend on the specifications of the vehicle manufacturer or radar manufacturer and / or the type of radar to be covered. Radar that resolves only in the horizontal direction requires an elongated radar region, while radar that resolves additionally in the vertical direction requires a relatively square or circular radar region.
[0051] exist Figure 2A , Figure 2B and Figure 2C In an exemplary embodiment, the radar region 7 has dimensions of 50mm × 100mm. In other exemplary embodiments, the radar region may include different dimensions. The dimensions may depend on the specifications of the vehicle manufacturer or radar manufacturer, the size of the radome, the radar's emission angle, the distance between the radar and the radome, and other factors. The radar region may also include certain tolerances, meaning that under certain installation conditions, the radar beam may not completely fill the radar region 7, but only cover (i.e. radiate through) a smaller portion of the radar region 7.
[0052] like Figure 2A and 2BAs shown, at least one interface 4 is at least partially disposed in the radar region 7. An exemplary embodiment is the interface 4 between the first plastic component 1 and the second plastic component 2. Since the third plastic component 3 is located on top of the first plastic component 1 and the second plastic component 2 in the form of a cover layer, a portion of the interface 5 between the third plastic component 3 and the first plastic component 1, and a portion of the interface 6 between the third plastic component 3 and the second plastic component 2, are also disposed in the radar region 7 (see [link to documentation]). Figure 1B ).
[0053] exist Figure 2A and 2B In an exemplary embodiment, interfaces 4, 5, and 6 extend inside and outside the radar region 7. In other exemplary embodiments, the interfaces may extend entirely inside the radar region, i.e., these interfaces do not extend outside the radar region. However, according to the present invention, at least a portion of the interfaces extends inside the radar region.
[0054] Figure 2B A top view of the radome 10 of an exemplary embodiment is shown. Figure 2C It shows along Figure 2B The cross-sectional view of line AA in the diagram. (See diagram below.) Figure 2C As shown, the radome 10 has a substantially constant thickness within the radar region 7. On the one hand, the thickness cannot be too large to avoid causing too much damage to radar transmission; on the other hand, it cannot be too thin so that the radome is stable enough to protect the radar located beneath it.
[0055] like Figure 2A and 2B As shown, the radome 10 of the exemplary embodiment includes two so-called injection points 8a and 8b. Injection points are necessary to inject plastic forming the plastic parts 1, 2, 3 into the injection cavity. These are typically openings in a mold or a corresponding closed mold. Openings typically leave tactile and visible features in the finished plastic parts, particularly the injection points. In the exemplary embodiment, injection points 8a and 8b are located outside the radar region 7. Therefore, the influence of injection points 8a and 8b on the transmitted radar waves is avoided.
[0056] In other exemplary embodiments, the radome 10 includes more or fewer than two injection points. This can depend on the design of the radome 10, the plastic used, and in particular its flow characteristics and process parameters.
[0057] In other exemplary embodiments, the radome may also include fastening devices such as screw holes, clamps, springs, etc., outside the radar area to mount the radome on the vehicle in front of the radar.
[0058] As previously described, the radome 10 of the exemplary embodiment shown in the figure is produced by a three-part injection molding method. In this case, a first plastic component 1 is injected into a first cavity at the injection point already described under pressure and heat. The first cavity can be formed by a mold and a corresponding counterpart of a closing mold. Thus, the first cavity defines the shape of the first plastic component 1. The injected first plastic component 1 is then transferred to a second cavity, i.e., removed from the first cavity and inserted into the second cavity. For this purpose, the first plastic component 1 can remain in the mold, which moves from a first counterpart closing the first cavity to a second counterpart closing the second cavity.
[0059] The second cavity, formed by the mold and the second counterpart, is larger than the first cavity because the latter contains the voids required for the second plastic component 2. The second plastic component 2 is then injection molded into the second cavity at the injection point already described, and chemically bonded to the first plastic component 1 already in the mold.
[0060] Finally, the mold having the first plastic component 1 and the second plastic component 2 is converted a second time into a third corresponding component, which, together with the mold, forms a third cavity, which in turn includes a cavity for injection molding the third plastic component 3. The third plastic component 3 is then injection molded into the cavity at the already explained injection point and chemically bonded to the first and second plastic components. In an exemplary embodiment with two plastic components, these steps, particularly the conversion to the third corresponding component and the injection molding of the third plastic component, are omitted. If there are three or more components, correspondingly more conversion and injection molding steps are required.
[0061] After the final injection molding step, the completed radome 10 is removed from the mold and allowed to cool. Post-processing steps can then be performed.
[0062] All descriptions of the radome according to the invention, especially its advantages, apply accordingly to the described production method.
