The outer surface of the lampshade is coated with a hydrophobic coating, which is conducive to the rapid downward flow of water droplets. Under the action of the deicing component, there is no need to manually de-ice in cold weather, and improper operation can avoid adverse effects on the front cover of the car light.

[0017] 2. When the present invention is used, the temperature sensor is started to detect the temperature inside the lampshade. The controller intelligently adjusts the wind speed of the micro fan and the power of the heating wire according to the received temperature data to avoid abnormal temperature inside the lampshade and affect the deicing effect.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1-Figure 10As shown, the present invention provides a technical solution: a deicing structure for a headlight, comprising a shell 1, a deicing assembly 3 is arranged inside the shell 1, a drainage assembly 4 is arranged at the bottom of the shell 1, a mounting groove 5 is opened on the front surface of the shell 1, a lampshade 2 is arranged inside the mounting groove 5, and a hydrophobic coating is arranged on the outer surface of the lampshade 2; the deicing assembly 3 comprises a graphene heat pipe 301, a heating wire 302 is arranged inside the graphene heat pipe 301, the heating wire 302 is used to heat the wind, the graphene heat pipe 301 is used to bend the wind flow and transport it to the heating wire 302 for heating, four air inlet pipes 308 are fixedly connected at the top of the front surface of the graphene heat pipe 301, one end of the four air inlet pipes 308 is fixedly connected to a fixed pipe 303, a plurality of air outlet pipes 304 are fixedly connected at the front surface of the outer surface of the fixed pipe 303, and the plurality of air outlet pipes 304 are used to heat the graphene heat pipe The hot air meandering in the tube 301 and heated by the heating wire 302 blows toward the inner wall of the lampshade 2, a control groove 11 is opened at the bottom of the rear surface of the shell 1, and a controller 12 is installed on the inner wall of the control groove 11 by screws, an infrared sensor 9 is arranged at the bottom of the rear surface wall inside the shell 1, and a temperature sensor 10 is arranged at the top of the rear surface wall inside the shell 1, and a micro fan 305 is fixedly installed inside the control groove 11, and the input end of the micro fan 305 is fixedly connected to the air intake pipe 309, and the output end of the micro fan 305 is fixedly connected to the first connecting pipe 306, and one end of the first connecting pipe 306 is fixedly connected to the shunt pipe 307, and both ends of the shunt pipe 307 are fixedly connected to the bottom of the graphene heat pipe 301, and one end of the first connecting pipe 306 is fixedly passed through the interior of the shell 1, and the rear surface of the graphene heat pipe 301 is installed on the rear surface wall inside the shell 1 through an auxiliary rod.

[0024] In this embodiment, when in use, the infrared sensor 9 is first started. By using the thermal radiation characteristics of infrared rays, the thermal radiation characteristics of the ice layer and the lampshade 2 itself are different. The infrared sensor 9 can detect the infrared energy emitted by the object and judge whether there is an ice layer outside the lampshade 2 based on the difference in energy. When there is an ice layer, the infrared radiation signal of the ice layer is different from the infrared radiation signal of the lampshade 2. The sensor identifies the ice layer by analyzing these signal differences and transmits the detected signal to the controller 12. When the controller 12 receives the signal of the existence of the ice layer, it starts the micro fan 305 and the heating wire 302, and transports the wind to the first connecting pipe 306 through the air inlet pipe 309, and transports the wind to the graphene heat pipe 301 through the shunt pipe 307. The graphene heat pipe 301 is arranged in a curved shape, such as Figure 6As shown, it is beneficial to extend the flow path of the wind and fully contact the heating wire 302. After the heating wire 302 is started, heat is generated and transferred to the graphene heat pipe 301, and the wind flowing inside the graphene heat pipe 301 is heated to form hot wind. Then the hot wind enters the fixed pipe 303 through the air inlet pipe 308, and finally the hot wind is blown to the inner wall of the lampshade 2 through multiple air outlet pipes 304, thereby heating the lampshade 2. At the same time, the graphene heat pipe 301 has good thermal conductivity. While blowing hot wind, the heat is transferred to the inside of the lampshade 2, which helps to increase the heat of the lampshade 2, so that the ice layer on the outer surface of the lampshade 2 is heated and melted, achieving the effect of intelligent automatic deicing. The outer surface of the lampshade 2 is coated with a hydrophobic coating, which can make water droplets roll quickly on the surface. When the ice layer melts and becomes water, it is beneficial for the water droplets to be quickly discharged downward along the arc surface of the lampshade 2. The outlet end of the air outlet pipe 304 is located at the top of the inside of the lampshade 2. After the hot air blows onto the lampshade 2, it will flow downward along the arc surface of the lampshade 2, which is conducive to uniform heating of the lampshade 2 and better deicing. Under the action of the deicing component 3, there is no need to manually de-ice in cold weather, avoiding the adverse effects of improper operation on the headlight cover, and solving the problem that the hands are easily frozen when manually de-icing the headlight cover in a cold environment, resulting in improper operation during the scraping process, such as excessive force or inappropriate tool angle, which can easily scratch the surface of the headlight cover, affecting the light transmittance and aesthetics of the headlight cover, and also reducing the service life of the headlight cover. When the infrared sensor 9 detects that the ice layer of the lampshade 2 has melted, the controller 12 will control the micro fan 305 and the heating wire 302 to turn off.

[0025] Embodiment 2: Figure 4-Figure 6 As shown, the de-icing component 3 includes a graphene heat pipe 301, a heating wire 302 is arranged inside the graphene heat pipe 301, and the heating wire 302 is used to heat the wind. The graphene heat pipe 301 is used to bend the wind flow and transport it to the heating wire 302 for heating. A control groove 11 is opened at the bottom of the rear surface of the shell 1, and a controller 12 is installed on the inner wall of the control groove 11 by screws. An infrared sensor 9 is arranged at the bottom of the rear surface wall inside the shell 1, and a temperature sensor 10 is arranged at the top of the rear surface wall inside the shell 1. A micro fan 305 is fixedly installed inside the control groove 11, and an input end of the micro fan 305 is fixedly connected to an air intake pipe 309, and an output end of the micro fan 305 is fixedly connected to a first connecting pipe 306, and one end of the first connecting pipe 306 is fixedly connected to a shunt pipe 307, and both ends of the shunt pipe 307 are fixedly connected to the bottom of the graphene heat pipe 301, and one end of the first connecting pipe 306 is fixedly penetrated into the shell 1.

[0026] In this embodiment, when in use, the heating wire 302, the micro fan 305, the electric push rod 412, the infrared sensor 9, the temperature sensor 10 and the controller 12 are electrically connected. When the deicing component 3 de-ices the lampshade 2, the temperature sensor 10 is started to detect the temperature inside the lampshade 2, and the detected temperature data is transmitted to the controller 12 in the form of an electrical signal for identification and comparison. The controller 12 intelligently adjusts the wind speed of the micro fan 305 and the power of the heating wire 302 according to the received temperature data to avoid abnormal temperature inside the lampshade 2 and affect the de-icing effect. When de-icing is not required, only the micro fan 305 is started to transmit wind to the inside of the lampshade 2, and the moisture that may exist inside the lampshade 2 is removed by the flowing wind force, so as to prevent the condensation of moisture into water droplets and affect the lighting effect, maintain the dry environment inside the lampshade 2, avoid light scattering and refraction caused by water droplets, and prevent the inner wall of the lampshade 2 from icing, thereby achieving a dehumidification effect.

[0028] In this embodiment, when in use, the electric push rod 412 is started to pull the T-shaped insulation plug 406 away from the drain pipe 401, driving the air outlet pipe 410 and the second connecting pipe 409 to move, and the telescopic tube 408 is unfolded, which does not affect the subsequent discharge of the drain pipe 401. When the de-icing component 3 is working, after the hot air blows to the inner wall of the lampshade 2, it flows downward along the arc-shaped inner wall of the lampshade 2, and at the same time blows the condensed water droplets formed on the inner wall of the lampshade 2 downward, and the condensed water droplets flow downward along the arc-shaped surface of the lampshade 2 and flow into the drain groove 6, and then enter the water inlet pipe 402 through the drain hole 7, and finally discharge the condensed water through the drain pipe 401, so as to prevent the condensed water from adhering to the inner wall of the lampshade 2 and freezing again. At the same time, the hot air enters the L-shaped tube 405 through the exhaust hole 8, and then enters the insulation sleeve 403 and the connecting sleeve 404 to insulate the drain pipe 401 and the water inlet pipe 402, so as to prevent the condensed water from freezing due to the external low temperature when flowing in the drain pipe 401, thereby affecting the normal discharge of the subsequent condensed water.

When the de-icing assembly 3 is working, after the hot air blows to the inner wall of the lampshade 2, it flows downward along the arc-shaped inner wall of the lampshade 2, and at the same time blows the condensed water droplets formed on the inner wall of the lampshade 2 downward, flows into the drain groove 6, and then enters the water inlet pipe 402 through the drain hole 7, and finally discharges the condensed water through the drain pipe 401. In addition, the hot air enters the L-shaped pipe 405 through the exhaust hole 8, and then enters the insulation sleeve 403 and the connecting sleeve 404, and insulates the drain pipe 401 and the water inlet pipe 402. Then the hot air enters the telescopic pipe 408 and the second connecting pipe 409 through the reinforcement pipe 407, and then enters the inside of the T-shaped insulation plug 406, and finally is discharged through the outlet pipe 410. When the infrared sensor 9 detects that the ice layer of the lampshade 2 has melted, the controller 12 will control the micro fan 305 and the heating wire 302 to turn off, and start the electric push rod 412 again to push the T-shaped insulation plug 406 into the drain pipe 401 to block the drain pipe 401.
