Technical Field
[0001] This application relates to the field of automotive lighting, and more specifically, to a radar-transmitting luminous vehicle logo light. Background Technology
[0002] A car logo is the emblem used to represent a car brand. Car logo lights not only serve as product symbols but also begin to illuminate synchronously with other lights in the same position. In recent years, some car logo lights have also incorporated radar-transmitting capabilities.
[0003] However, when a car logo light has the function of transmitting radar waves, ice and snow will accumulate on the surface of the logo in icy and snowy weather, which will seriously affect the radar wave detection function and thus affect the driving safety of the car. Therefore, the car logo light needs a fast snow melting function to cope with this harsh weather.
[0004] Therefore, a radar-transmitting luminous vehicle marking light capable of snow removal is needed to meet the usage requirements. Utility Model Content

[0039] The features and performance of the radar-transmitting luminous vehicle logo light of this application are further described in detail below with reference to embodiments.
[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this application embodiment provides a radar-transmitting luminous car logo light, including a base 100, an outer cover 200 connected to the top of the base 100, a circuit board 300 fixed between the base 100 and the outer cover 200, a light shield 400 fixed between the circuit board 300 and the outer cover 200, a light guide plate 500 fixed between the circuit board 300 and the outer cover 200, a heating film 600 connected to the surface of the outer cover 200 away from the base 100, and an outer decorative ring 700 detachably connected to the base 100;
[0041] The base 100 has an upwardly protruding central section forming a radar-transparent area 110 and a receiving groove 120 located on the bottom surface of the radar-transparent area 110. The receiving groove 120 is used to accommodate a millimeter-wave radar sensor, which is used to emit radar signals that pass through the radar-transparent area 110 for detection. The edge of the base 100 has seven spaced-apart hot-melt pillars 140. The circuit board 300 has a first opening 310 in the center for the radar-transparent area 110 to pass through. The edge of the circuit board 300 away from the base 100 has circumferentially spaced LED lights 320. The circuit board 300 passes through seven corresponding... The connecting holes are fitted and welded to each hot melt pillar 140; the light shield 400 is fitted onto the outside of the radar wave-transmitting area 110 through the second opening 410 in the middle, the top edge of the radar wave-transmitting area 110 is recessed to form a positioning groove 130 that snaps into and supports the inner wall of the second opening 410 in the middle of the light shield 400, and the outer periphery of the light shield 400 protrudes downward to form a light blocking part 420 located inside each LED lamp 320; the bottom surface of the light guide plate 500 presses against and fits the radar wave-transmitting area 110 and the top surface of the light shield 400, and the side surface of the light guide plate 500 away from the base 100 is provided with a car logo 510, and the outer periphery of the light guide plate 500 faces towards The lower protrusion forms a light-incident portion 520 aligned with each LED 320, and the light-incident portion 520 is located outside the light-blocking portion 420; in this embodiment, the vehicle logo 510 is a three-pointed star shape; the bottom wall of the outer cover 200 presses against and adheres to the top surface of the light guide plate 500, and the outer cover 200 has a logo groove 210 on the side facing the bottom surface of the light guide plate 500 to accommodate and adhere to the vehicle logo 510. The inner wall of the logo groove 210 is provided with an indium-plated layer, and the bottom surface of the outer cover 200 includes an opaque area 220 coated with a light-shielding layer, a first light-transmitting area 230 located at the edge of the logo groove 210, and three arc-shaped second light-transmitting areas 240 arranged at intervals along the circumference of the outer cover 200. The indium layer is located between the inner wall of the marking groove 210 and the opaque area 220. The two ends of each second light-transmitting area 240 are connected to the first light-transmitting area 230 to form a whole. In this embodiment, the light-shielding layer is a black paint layer. A heating film 600 is provided on the top surface of the outer cover 200 away from the light guide plate 500. The heating film 600 and the outer cover 200 are inlaid and injection molded. A hardening layer is provided on the side of the heating film 600 away from the base 100. The outer decorative ring 700 is provided with six buckles 710 arranged at intervals along its circumference. When the outer decorative ring 700 is connected to the base 100 through each buckle 710, it presses against the outer peripheral wall of the heating film 600 away from the base 100.
[0042] In this embodiment, the base 100, outer cover 200, light guide plate 500, and heating film 600 are all made of PC material (polycarbonate). A heating mesh made of copper wire is embedded inside the heating film 600, and the positive and negative electrodes of the heating mesh are electrically connected to the circuit board 300 through PIN pins 610, respectively. The thicknesses of the base 100, outer cover 200, light guide plate 500, and heating film 600 are all integer multiples of half the wavelength of the millimeter-wave radar sensor's transmitting radar. The heating film 600, PIN pins 610, and outer cover 200 are inlaid and injection molded.
[0043] The radar-transparent luminous logo light provided in this embodiment forms a radar-transparent area 110 by protruding upwards in the middle of the base 100. This allows for the simultaneous mounting of the radar-transparent logo light onto the vehicle body and the fixing of a millimeter-wave radar sensor within the receiving groove 120 at the bottom of the radar-transparent area 110. This enables the LED lights 320, fixed between the base 100 and the light shield 400, to emit light. The light shield 400, fixed between the circuit board 300 and the light guide plate 500, blocks the light emitted by the LED lights 320. This allows the light emitted by the LED lights 320, arranged circumferentially along the edge of the circuit board 300, to enter the light-incident portion 520 formed by the downward protrusion of the outer periphery of the light guide plate 500 between the light shield 400 and the outer cover 200. This ensures that the light entering the light-incident portion 520 is refracted and diffused within the light guide plate 500. The logo 510, protruding at the top, emits light through the first light-transmitting area 230 and the second light-transmitting area 240 on the outer cover 200. This light illuminates the edge of the logo groove 210 and the three arc-shaped second light-transmitting areas 240 spaced apart around the circumference of the outer cover 200, highlighting the shape of the logo 510. Simultaneously, the radar waves emitted by the millimeter-wave radar sensor pass through the radar wave-transmitting area 110 and then further pass through the sequentially attached light guide plate 500, outer cover 200, and heating film 600 before exiting. This avoids the circuit board 300 and the light shield 400 blocking the radar waves and reduces the obstruction of the radar waves by the light guide plate 500, outer cover 200, and heating film 600. At the same time, the heating film 600, located on the surface of the outer cover 200 away from the base 100, can heat and melt the accumulated ice and snow on the surface, preventing the ice and snow from blocking the radar waves passing through the outer cover 200.
[0044] The radar-transparent area 110 has a recessed top edge forming a positioning groove 130 that engages and supports the inner wall of the second opening 410 in the middle of the light shield 400. This allows operators to easily position the light shield 400 at the top of the radar-transparent area 110 and use the radar-transparent area 110 to stably support the light shield 400. The outer periphery of the light shield 400 protrudes downward to form a light-blocking part 420 located inside each LED lamp 320 and the light-incident part 520. This allows the light emitted by each LED lamp 320 to be blocked by the light shield 400 and the light-blocking part 420, ensuring that the light emitted by each LED lamp 320 can only enter the light guide plate 500 through the light-incident part 520 and then exit, thus ensuring the uniformity and stability of the light. The outer cover 200 has a side facing the bottom of the light guide plate 500 that accommodates and affixes the vehicle logo 51. The 0-shaped marking groove 210 serves two purposes: firstly, it allows the raised car logo 510 and the marking groove 210 to fit together, ensuring radar wave transmission and reducing attenuation; secondly, it allows the car logo 510 and the marking groove 210 to work together to highlight the three-dimensional shape of the car logo 510. The bottom surface of the outer cover 200 includes an opaque area 220 coated with a black paint layer, a first light-transmitting area 230 located at the edge of the marking groove 210, and three arc-shaped second light-transmitting areas 240 arranged at intervals along the circumference of the outer cover 200. The black paint layer coated on the outer cover 200 can obscure the first light-transmitting area 230 and the second light-transmitting area 240 to form a light-emitting pattern of the car logo 510 located at the edge of the marking groove 210 and a prominent shape surrounding the car logo 510. The indium plating layer provided on the inner wall of the marking groove 210 achieves a 3D metal shape.
[0045] The base 100, outer cover 200, light guide plate 500, and heating film 600 are all made of polycarbonate. The thicknesses of these components are integer multiples of half the wavelength of the millimeter-wave radar sensor, further reducing their impact on radar wave transmission. A copper wire heating mesh is embedded inside the heating film 600. The positive and negative terminals of the heating mesh are connected to the circuit board 300 via pins 610. When voltage is input to the circuit board 300, the copper wire heating mesh conducts electricity, achieving uniform heating and de-icing functions, preventing heating failure due to a single broken copper wire. A hardened paint layer is applied to the side of the heating film 600 away from the base 100 for protection.
[0046] A detachable outer decorative ring 700 is connected to the side of the outer cover 200 away from the base 100. When the outer decorative ring 700 is connected to the base 100 via a snap fastener 710, it presses against the outer peripheral wall of the heating film 600 on the side away from the base 100. This serves two purposes: firstly, it presses against, fixes, and protects the heating film 600; secondly, the outer decorative ring 700 also serves a decorative function. The heating film 600 and the outer cover 200 are inlaid and injection molded, ensuring a stable connection between the heating film 600 and the outer cover 200, preventing the heating film 600 from aging and falling off after prolonged use, and extending the service life of the heating film 600.
[0047] The embodiments described above are some, but not all, of the embodiments of this application. The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
