Technical Field
[0001] The present invention relates to the technical field of defrosting and defogging of automobile lamps, and in particular to an intelligent system and method for defrosting, defogging and heat dissipation of automobile lamps. Background Art
[0002] Automobile lights are various traffic lights installed on cars to ensure safe driving, and are divided into two categories: lighting lights and signal lights. From 1905 to 1912, in order to solve the problem of road lighting ahead, spotlight acetylene headlights were installed, and a kerosene lamp was equipped as the rear license plate light. From 1945 to 1947, various external lamps that must be equipped at the minimum level were finalized. Qualified automobile lights should meet the corresponding photometric, chromatic and basic environmental test specifications. Automobile lights are generally divided into headlights, rear combination lights, fog lights, reversing lights, license plate lights and step lights, etc. Among them, the headlights of automobiles are the eyes of the car, which are not only related to the external image of a car owner, but also closely related to safe driving at night or in bad weather conditions.
[0003] For example, the announcement number CN207931675U is a car lamp with a temperature control and deicing function, including a nozzle, a support frame and a deicing agent tank, a first car lamp body is installed on the outer end surface of one side of the support frame, and a second car lamp body is installed on the outer end surface of the other side of the support frame, a temperature sensor is installed inside the first car lamp body, a motor is installed on the front surface of the first car lamp body and the second car lamp body, and a connecting rod is movably installed on the upper surface of the motor, a brush rod is movably installed on the upper surface of the connecting rod, and a brush and a heating wire are installed on the rear surface of the brush rod, the deicing agent tank is installed on the rear surface of the support frame, and a water pump is installed inside the deicing agent tank, a first connecting pipe is installed on one side of the water pump, and a second connecting pipe is installed on one side of the first connecting pipe, and the first connecting pipe and the second connecting pipe are installed on the front surface of the first car lamp body and the second car lamp body. The utility model can efficiently de-ice and is more convenient to use.
[0004] The above patent can remove ice efficiently and is more convenient to use. Currently, most automotive lamps use anti-fog coatings or desiccants to eliminate fog and frost problems. However, anti-fog coatings and desiccants have the disadvantage of limited service life. After the service life is exceeded, the lamps will still frost and fog. Therefore, regular maintenance or replacement is required, which will increase the cost of use and affect normal use. There are no corresponding warning measures after aging. When the illumination range of the headlights changes, traffic accidents may occur, and safety cannot be guaranteed during driving.
[0005] In view of the above problems, an intelligent system and method for defrosting, defogging and heat dissipation of automobile lamps are proposed. Summary of the invention
[0006] The purpose of the present invention is to provide an intelligent system and method for defrosting, demisting and heat dissipation of automobile lamps. The device is used to work, thereby solving the problem of eliminating fog and frost in the current automobile lamps in the above background. However, the anti-fog coating or desiccant has the disadvantage of limited service life. After the service life is exceeded, the lamps will still frost and fog. Therefore, regular maintenance or replacement is required, which increases the cost of use and affects normal use. There is no corresponding warning measure after aging. When the illumination range of the lamps changes, traffic accidents may occur, and safety cannot be guaranteed during driving.
[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a defrosting and demisting heat dissipation device for automobile lamps, comprising an automobile body and a lamp installed on the outside of the automobile body, reserved holes are opened on both sides of the automobile body, the lamp is threadedly installed in the reserved hole, a protective cover is fixedly installed on the outer wall of the reserved hole, a temperature sensor and a humidity sensor are respectively arranged inside the lamp, an air outlet pipe and an air inlet pipe are respectively fixedly installed on the side walls of the protective cover, and a breathable membrane is fixedly installed inside the air inlet pipe.
[0008] Furthermore, a fan is fixedly installed inside the air outlet pipe, and a one-way valve is fixedly installed inside the air outlet pipe.
[0009] Furthermore, the fan is electrically connected to the humidity sensor and the temperature sensor respectively.
[0010] The present invention also discloses an implementation method of an intelligent system for defrosting, defogging and heat dissipation of automobile lamps, comprising the following steps:
[0011] S1: The humidity sensor detects the humidity in the reserved hole, and the temperature sensor detects the temperature in the reserved hole;
[0012] S2: When the temperature in the reserved hole is normal, the fan is in standby mode; when the temperature in the reserved hole is high, the temperature sensor sends a signal to the fan to start the fan; when the humidity in the reserved hole is normal, the fan is in standby mode; when the humidity in the reserved hole is high, the humidity sensor sends a signal to the fan to start the fan;
[0013] S3: When the fan is working, the gas with high temperature and humidity in the reserved hole is discharged to the outside through the outlet pipe, the air in the reserved hole is reduced and the air pressure becomes smaller, and air is input into the reserved hole through the breathable membrane set in the air inlet pipe; when the fan is on standby, the one-way valve can be set to prevent air from freely entering and exiting the outlet pipe. When the fan is on standby, the air pressure in the chamber does not change, and the breathable membrane hinders the air flow.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] When the temperature in the reserved hole is high, the temperature sensor detects that the temperature in the reserved hole exceeds the set value, and starts the fan to extract the high-temperature gas in the reserved hole to the outside. The air pressure in the reserved hole is reduced, and the breathable membrane sucks the outside air into the reserved hole to achieve air replacement. Similarly, when the humidity is high, the humidity sensor will start the fan to repeat the above steps to discharge the air in the reserved hole to the outside for replacement. This device effectively solves the problem of fogging and frosting of lamps caused by the expiration of the life of the anti-fog coating and desiccant, thereby ensuring that the lamps are in normal working condition for a long time and ensuring the safety of drivers and vehicles.

[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 described embodiments 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] To solve technical problems such as Figure 1 - Figure 5As shown, the following preferred technical solutions are provided: a defrosting, demisting and heat dissipation device for automobile lamps, comprising an automobile body 1 and a lamp 2 installed on the outside of the automobile body 1, reserved holes 11 are opened on both sides of the automobile body 1, the lamp 2 is threadedly installed in the reserved hole 11, a protective cover is fixedly installed on the outer wall of the reserved hole 11, a temperature sensor 4 and a humidity sensor 3 are respectively arranged inside the lamp 2, an air outlet pipe 5 and an air inlet pipe 8 are respectively fixedly installed on the side walls of the protective cover, a breathable membrane 9 is fixedly installed inside the air inlet pipe 8, the breathable membrane 9 is used to filter moisture and dust impurities in the air, the humidity sensor 3 and the temperature sensor 4 are both set with a maximum threshold value of normal working temperature, when it is detected that the temperature exceeds the set value, the fan 6 will be automatically started to draw the air in the reserved hole 11 outward, the lamp 2 includes headlights, rear combination lights, fog lights, reversing lights, license plate lights, step lights and other lamps arranged on the outside of the vehicle body.
[0024] A fan 6 is fixedly installed inside the air outlet pipe 5, and a one-way valve 7 is fixedly installed inside the air outlet pipe 5. The fan 6 is used to draw the air inside the reserved hole 11 outward. The setting of the one-way valve 7 can hinder the normal flow of air. The air outlet pipe 5 can be set at any position connected to the protective cover except the protective cover on the outer wall of the reserved hole 11. The one-way valve 7 can be set on the inside or outside of the fan 6, and can be flexibly set according to specific circumstances.
[0025] The fan 6 is electrically connected to the humidity sensor 3 and the temperature sensor 4 respectively. The fan 6 can be started when the detection results of the humidity sensor 3 and the temperature sensor 4 reach the set value.
[0026] The present invention also discloses an implementation method of an intelligent system for defrosting, defogging and heat dissipation of automobile lamps, comprising the following steps:
[0027] S1: The humidity sensor 3 detects the humidity in the reserved hole 11, and the temperature sensor 4 detects the temperature in the reserved hole 11;
[0028] S2: When the temperature in the reserved hole 11 is normal, the fan 6 is in a standby state; when the temperature in the reserved hole 11 is high, the temperature sensor 4 transmits a signal to the fan 6 to start the fan 6; when the humidity in the reserved hole 11 is normal, the fan 6 is in a standby state; when the humidity in the reserved hole 11 is high, the humidity sensor 3 transmits a signal to the fan 6 to start the fan 6;
[0029] S3: When the fan 6 is working, the gas with high temperature and humidity in the reserved hole 11 is discharged to the outside through the outlet pipe 5, the air in the reserved hole 11 is reduced and the air pressure becomes smaller, and air is input into the reserved hole 11 through the breathable membrane 9 arranged in the inlet pipe 8; when the fan 6 is on standby, the one-way valve 7 can be set to prevent air from freely entering and exiting the outlet pipe 5. When the fan 6 is on standby, the air pressure in the chamber 11 does not change, and the breathable membrane 9 hinders the air flow.
[0030] Specifically, during the driving of the car, the difference between the temperature and humidity of the outside and the temperature generated when the headlight 2 in the reserved hole 11 is working, when the difference between the temperature and humidity of the outside and the temperature and humidity in the reserved hole 11 is large, the transparent protective cover outside the reserved hole 11 will produce a layer of water mist on the protective cover due to the large temperature difference, and the water mist will cause the light transmission of the headlight 2 through the protective cover to be affected by the water mist, resulting in the illumination range of the headlight 2 being affected. When the temperature generated when the headlight 2 in the reserved hole 11 is working is high, resulting in a high temperature in the reserved hole 11, at this time, the temperature in the reserved hole 11 is detected by the temperature sensor 4. When the temperature exceeds the set value, the temperature sensor 4 starts the fan 6, and the fan 6 draws out the high-temperature gas in the reserved hole 11 through the outlet pipe 5. At this time, the air pressure in the reserved hole 11 decreases. Under the action of the air pressure, the breathable membrane 9 in the intake pipe 8 sucks the outside air into the reserved hole 11 to achieve air replacement. Similarly, when the humidity is high, the humidity sensor 3 will start the fan 6 and repeat the above steps to discharge the air with high humidity in the reserved hole 11 to the outside for replacement. The device effectively solves the problem of fogging and frosting of lamps caused by the expiration of the life of the anti-fog coating and the desiccant, thereby ensuring that the lamps are in normal working condition for a long time and ensuring the safety of drivers and passengers and vehicles.
