DETAILED DESCRIPTION

[0017] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] In cold and snowy areas, the surface of the car logo is prone to snow and ice accumulation, which poses a serious challenge to the performance of the ACC radar integrated in the car logo. Snow and ice will absorb, scatter or reflect radar waves, causing radar signals to attenuate, distort or even be completely blocked, seriously affecting the detection accuracy and reliability of the ACC system, and thus affecting the vehicle's driving safety.

[0020] A luminous ACC car logo with automatic de-icing and heating control function, such as Figures 1-6As shown, it includes an inner cover 2 and an outer cover 3 installed on the shell 1. The outer cover 3 is tightly fitted with the shell 1. Luminous lines are set in the outer cover 3. The surface of the outer cover 3 is provided with a metal coating (wherein the metal coating adopts NCVM non-conductive thin film technology, and the thickness of the metal coating is controlled at the nanometer level, taking into account the metallic texture of the car logo and radar penetration), so that the outer surface of the outer cover 3 has a metalized appearance, and the logo features are highlighted by the luminous lines in the outer cover 3. In addition, both the inner cover 2 and the outer cover 3 adopt metal indium plating technology to achieve the function of penetrating radar waves, without harmful substances such as hexavalent chromium produced by water electroplating, while meeting the metallic texture. The outer surface of the outer cover 3 is smooth. A radiator 4 and an integrated circuit board 5 are installed in the housing 1. The external vehicle is equipped with a control terminal (not shown in the figure). The radiator 4 and the integrated circuit board 5 are both electrically connected to the control terminal. A heater 6 electrically connected to the control terminal is installed in the housing 1. The radiator 4, the integrated circuit board 5 and the heater 6 are arranged in sequence from close to the housing 1 to far away. A heating diaphragm is installed in the housing 1. The heating diaphragm is pre-formed by a hot stamping process and then integrated with the mask by an insert injection molding process. The heating diaphragm is transparent and has a heating wire with a diameter of 0.02mm-0.2mm, does not affect optics, nor does it affect radar transmission performance. A rain sensor is arranged on the surface of the headlight or other positions of the vehicle body to sense ice and snow or its melted products. When the requirements are met, the heating system is turned on or stopped. When in use, after the rain sensor senses ice and snow, the control terminal turns on the radiator 4, heater 6 and heating diaphragm. The heater 6 and heating diaphragm heat the inner mask 2 and the outer mask 3 to quickly melt the ice and snow covered on the outer surface of the outer mask 3. The middle of the radiator 4, integrated circuit board 5 and heater 6 are all provided with through holes. The housing 1 is provided with a radar 101. The radar 101 signal passes through the luminous lines, and the luminous lines can meet The radar 101 signal has a high penetration requirement. To reduce the loss of the 76GHz to 77GHz millimeter-wave radar when penetrating the vehicle logo, the base material of the inner mask 2 and the outer mask 3 is a plastic material with a low dielectric constant (such as liquid crystal polymer LCP). The radar 101 is embedded in the through hole in the middle of the heat sink 4, the integrated circuit board 5 and the heater 6 to reduce the obstruction of the radar 101 by the heat sink 4, the integrated circuit board 5 and the heater 6. While heating the outer mask 3, the area blocked by the radar 101 is reduced. The outer mask 3 is heated by the heater 6 and the heating diaphragm to melt the ice and snow on the outer mask 3, thereby reducing the risk of radar 101 being blocked by the ice and snow covering the outer mask 3. In order to reduce the probability of the radar 101 signal being affected, the accuracy of the radar 101 signal is guaranteed to improve the safety of vehicle driving. A fixing ring 7 is fixed to the right side of the radar 101. The fixing ring 7 is in contact with the inner mask 2. The fixing ring 7 is provided with a plurality of circumferentially distributed notches. The notches are used to introduce the hot air generated by the heater 6 and the heating diaphragm into the fixing ring 7 to heat the middle part of the inner mask 2 and the middle part of the outer mask 3. While reducing the blocked area of ​​the radar 101, the ice and snow adhering to the middle part of the outer mask 3 are heated to accelerate the melting speed of the ice and snow in the middle part of the outer mask 3, thereby reducing the probability of the radar 101 signal being blocked, and thus improving the radar 101 signal. To ensure high precision and enhance vehicle safety, radar 101 is equipped with several circumferentially distributed illumination lamps 8, electrically connected to the control terminal. All illumination lamps 8 direct their illumination toward the axis of the outer housing 3. Located around radar 101, these lamps utilize a V-shaped dot optical structure and a V-Cut laser processing technique to minimize the area where the light emitted by the lamps 8 obstructs the radar 101 signal. Assuming the light generated by the lamps 8 does not obstruct the radar 101 signal, the center of the outer housing 3 is illuminated. When the vehicle logo is no longer in use, the radiator 4, heater 6, and illumination lamps 8 are turned off via the control terminal.

[0021] Example 2

[0022] Simply relying on heat conduction to melt the ice layer close to the surface of the car logo, especially the thick ice layer, is often inefficient and time-consuming. During the ice melting process, the melted and loosened ice and snow will still adhere to the surface of the car logo. If the ice and snow fail to fall off the car logo completely in time, the melted snow water will re-condense on the car logo due to the cold weather, which will cause the radar signal to recover slowly or be unstable.

[0023] On the basis of Example 1, Figure 2 and Figure 5-Figure 7 As shown, the inner mask 2 is rotatably connected to a rotating ring 9, a torsion spring is fixed between the rotating ring 9 and the radar 101, the radar 101 is fixed to an outer sleeve 10, a thermal block 11 is arranged in the outer sleeve 10, and the thermal block 11 is a heat-expanding material, such as paraffin. After the heater 6 is turned on, the thermal block 11 senses the heat and melts and expands. The outer sleeve 10 is slidably connected to an inner slide rod 12, and the inner slide rod 12 is sealed and slidably connected in the outer sleeve 10, and the outer sleeve 10 is away from the thermal block 11. An exhaust hole is provided on one side of the thermosensitive block 11. The thermosensitive block 11 is located between the outer sleeve 10 and the inner slide 12. The inner slide 12 is fixed with an extrusion block 13. The rotating ring 9 is provided with a limiting groove 14. After the thermosensitive block 11 expands, the thermosensitive block 11 pushes the inner slide 12 to move. The inner slide 12 drives the extrusion block 13 to move. The extrusion block 13 squeezes the limiting groove 14 to rotate the rotating ring 9. The rotating ring 9 is provided with a plurality of circumferentially distributed holes 16. The radar 101 is fixed with a circumferentially distributed hole 16 and the number of holes is the same as that of the inner slide 12. The elastic telescopic rod 15 has the same number of holes 16, and the telescopic part of the elastic telescopic rod 15 is used to rush into the adjacent holes 16. Initially, the telescopic part of the elastic telescopic rod 15 is pressed by the rotating ring 9, and the telescopic part of the elastic telescopic rod 15 is in a force-storing contracted state. During the rotation of the rotating ring 9, the torsion spring of the rotating ring 9 twists and accumulates force. When the hole 16 rotates to align with the telescopic part of the adjacent elastic telescopic rod 15, the telescopic part of the elastic telescopic rod 15 extends and rushes into the hole 16, and the telescopic part of the elastic telescopic rod 15 impacts the rotating ring 9. The rotating ring 9 transmits the impact force to the inner mask 2 and the outer mask 3, so that the outer mask 3 is affected by the impact, and the ice and snow on the outer mask 3 are assisted to fall off. In the process of melting the ice and snow on the outer mask 3, the ice and snow on the outer mask 3 are slightly moved, which speeds up the falling speed of the ice and snow on the outer mask 3, thereby reducing the probability of the radar 101 signal being blocked by ice and snow, thereby improving the accuracy of the radar 101 signal, thereby improving the safety of vehicle driving.

[0024] like Figure 7As shown, the hole 16 is fixed with an elastic block 17, and the telescopic portion of the elastic telescopic rod 15 is used to squeeze the elastic block 17. The elastic coefficient of the elastic telescopic rod 15 is smaller than the elastic coefficient of the elastic block 17, and the elastic coefficient of the elastic block 17 is smaller than the elastic coefficient of the torsion spring on the rotating ring 9. When the ice and snow on the outer cover 3 fall off, the heater 6 is turned off by the control terminal. In the process of cooling and solidification of the thermal block 11, the torsion spring of the rotating ring 9 is reset, and the rotating ring 9 rotates and resets. The rotating ring 9 squeezes the extrusion block 13 through the limiting groove 14, and the extrusion block 13 moves and resets, so that the inner slide rod 12 moves and resets. In the process of rotation and reset, the rotating ring 9 drives all the elastic blocks 17 to rotate and reset. The elastic block 17 squeezes the telescopic portion of the elastic telescopic rod 15, and the elastic block 17 is compressed. Then the telescopic portion of the elastic telescopic rod 15 is squeezed and reset. After the telescopic portion of the elastic telescopic rod 15 is reset, the elastic block 17 rebounds and resets.

[0025] like Figure 6 and Figure 8 As shown, the rotating ring 9 is fixed with a flexible strip 18. Initially, the flexible strip 18 blocks all the gaps in the fixed ring 7 to reduce the probability of hot air entering the fixed ring 7 and affecting the radar 101 signal. The flexible strip 18 is provided with a plurality of circumferentially distributed flow grooves 19. The flow grooves 19 are used to connect the corresponding gaps on the fixed ring 7. During the use of this vehicle logo, if there is no rush to melt the ice and snow on the outer cover 3, the heat provided by the heater 6 is low, the thermal block 11 does not expand, the rotating ring 9 does not rotate, and hot air does not enter the fixed ring 7 to reduce the impact of hot air on the radar 101 signal. When the ice and snow need to be melted quickly and the thermal block 11 expands due to heat (the heat provided by the heater 6 is high), the rotating ring 9 rotates and drives the flexible strip 18 to rotate, so that all the flow grooves 19 move. When the rotating ring 9 rotates to the limit state, all the flow grooves 19 are connected to the fixed ring 7, allowing hot air to enter the fixed ring 7.

[0026] Example 3

[0027] On the basis of Example 2, Figure 8 As shown, an impact ball 20 is provided between the inner mask 2 and the outer mask 3, and elastic members are fixedly connected between the impact ball 20 and the inner mask 2 and the outer mask 3, wherein the elastic member is a spring. During the driving process of the vehicle, the elastic member is continuously deformed, causing the impact ball 20 to shake and impact the outer mask 3, causing the outer mask 3 to vibrate, shaking off the ice and snow on the outer surface of the outer mask 3, accelerating the probability of the ice and snow on the outer surface of the outer mask 3 falling off during the melting process, thereby reducing the obstruction of the ice and snow to the radar 101 signal, thereby improving the accuracy of the radar 101 signal.

[0028] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
