The circuit board 300 is provided with seven corresponding The connecting holes are sleeved and welded on each hot melt column 140; the light shielding plate 400 is sleeved on the outside of the radar transparent area 110 through the second opening 410 set in the middle, and the top edge of the radar transparent area 110 is recessed to form a positioning groove 130 for clamping and supporting the inner wall of the second opening 410 in the middle of the light shielding plate 400, and the outer peripheral edge of the light shielding plate 400 protrudes downward to form a light blocking portion 420 located on the inner side of each LED lamp 320; the bottom surface of the light guide plate 500 is pressed against the radar transparent area 110 and the top surface of the light shielding plate 400, and the surface of the light guide plate 500 on the side away from the base 100 is convex with a car logo 510, and the outer peripheral edge of the light guide plate 500 is facing The lower protrusion forms a light entrance portion 520 aimed at each LED lamp 320, and the light entrance 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 is pressed against the top surface of the light guide plate 500, and the outer cover 200 is provided with a logo groove 210 facing the bottom surface of the light guide plate 500 to accommodate and fit the vehicle logo 510. The inner wall of the logo groove 210 is provided with an indium plating 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, and the indium plating layer is provided. The indium layer is located between the inner wall of the identification groove 210 and the opaque area 220. The two ends of each second light-transmitting area 240 are respectively 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.

[0029] In this embodiment, the base 100, outer cover 200, light guide plate 500, and heater film 600 are all made of polycarbonate (PC). A copper wire heating mesh is embedded within the heater film 600. The positive and negative electrodes of the heating mesh are electrically connected to the circuit board 300 via pins 610. The thickness of the base 100, outer cover 200, light guide plate 500, and heater film 600 is an integer multiple of half the wavelength of the millimeter-wave radar sensor's transmitted radar. The heater film 600, pins 610, and outer cover 200 are inlaid and injection molded.

[0030] The radar-transmitting luminous vehicle mark light provided in the embodiment of the present application forms a radar-transmitting area 110 by bulging upward at the middle part of the base 100. The millimeter-wave radar sensor can be fixed in the receiving groove 120 at the bottom of the radar-transmitting area 110 while the radar-transmitting luminous vehicle mark light is installed on the vehicle body, thereby using the LED lamp 320 fixed on the circuit board 300 between the base 100 and the light shielding plate 400 to emit light, and the light shielding plate 400 fixed between the circuit board 300 and the light guide plate 500 to block the light emitted by the LED lamp 320, so that the light emitted by the LED lamp 320 arranged circumferentially at intervals along the edge of the surface of the circuit board 300 enters the light entrance portion 520 formed by the downward bulging outer peripheral edge of the light guide plate 500 between the light shielding plate 400 and the outer cover 200, thereby ensuring that the light entering the light entrance portion 520 is refracted and diffused inside the light guide plate 500 The vehicle logo 510 protruding from the top emits light through the first light-transmitting area 230 and the second light-transmitting area 240 on the outer cover 200, thereby emitting light at the edge of the logo groove 210 on the outer cover 200 and the three arc-shaped second light-transmitting areas 240 spaced apart along the circumference of the outer cover 200, highlighting the shape of the vehicle logo 510. At the same time, the radar waves emitted by the millimeter-wave radar sensor pass through the radar-transmitting area 110 and further pass through the sequentially bonded light guide plate 500, the outer cover 200 and the heating film 600 before being emitted, avoiding obstruction of the radar waves by the circuit board 300 and the sunshade 400, and reducing obstruction of the radar waves by the light guide plate 500, the outer cover 200 and the heating film 600. At the same time, the heating film 600 arranged on the surface of the outer cover 200 away from the base 100 can heat and melt ice and snow accumulated on the surface, preventing ice and snow from blocking the radar waves passing through the outer cover 200.

[0031] Among them, the top edge of the radar transparent area 110 is recessed to form a positioning groove 130 for clamping and supporting the inner wall of the second opening 410 in the middle of the light shielding plate 400, which can facilitate the operator to position the light shielding plate 400 on the top of the radar transparent area 110 and use the radar transparent area 110 to stably fix and support the light shielding plate 400; the outer peripheral edge of the light shielding plate 400 is convex downward to form a light blocking portion 420 located inside each LED lamp 320 and the light entrance portion 520, which can use the light shielding plate 400 and the light blocking portion 420 to block the light emitted by each LED lamp 320, limiting the light emitted by each LED lamp 320 to only enter the light guide plate 500 through the light entrance portion 520 and then be emitted, thereby ensuring the uniformity and stability of the light; the outer cover 200 is provided with a side facing the bottom surface of the light guide plate 500 to accommodate and fit the vehicle logo 51 0's logo groove 210, on the one hand, can make the raised vehicle logo 510 fit with the logo groove 210 to ensure the transmission of radar waves and reduce attenuation, and on the other hand, can use the vehicle logo 510 and the logo groove 210 to cooperate to highlight the three-dimensional shape of the vehicle 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 logo 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 mask the display of the first light-transmitting area 230 and the second light-transmitting area 240 to form a light emitting pattern of the vehicle logo 510 located at the edge of the logo groove 210 and a prominent shape surrounding the vehicle logo 510, and the 3D metal shape is achieved by the indium plating layer provided on the inner wall of the logo groove 210.

[0032] The base 100, outer cover 200, light guide plate 500, and heating film 600 are all made of polycarbonate. Their thickness is an integer multiple of half the wavelength of the millimeter-wave radar sensor's transmitted radar, further reducing their impact on radar wave transmission. A copper wire heating grid is embedded within the heating film 600. The positive and negative terminals of the heating grid are connected to the circuit board 300 via pins 610. When voltage is applied to the circuit board 300, the copper wire heating grid conducts electricity, achieving uniform heating and snow removal, preventing heating failure due to single copper wire breakage. A hardening lacquer coating is applied to the side of the heating film 600 facing away from the base 100, providing protection.

[0033] A removable outer decorative ring 700 is connected to the side of the outer cover 200 facing away from the base 100. When attached to the base 100 via a snap 710, the outer decorative ring 700 presses against the outer wall of the heating film 600 facing away from the base 100. This not only presses, secures, and protects the heating film 600, but also serves as a decorative element. The heating film 600 and the outer cover 200 are inlaid and injection-molded, ensuring a stable connection between them. This prevents the heating film 600 from aging and falling off after prolonged use, thereby extending the lifespan of the heating film 600.

[0034] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
