Description

Technical Field

[0001] This invention belongs to the field of in-vehicle lighting technology. Specifically, this invention relates to a pre-embedded low-power LED cold light system and control method for spider avoidance in vehicles. Background Technology

[0002] With the diversification of car usage scenarios, when vehicles are parked outdoors or near vegetation for extended periods, arthropods such as spiders can easily enter the car through door gaps and air conditioning vents, especially nesting and living in hidden areas such as the center console, door folds, and under seats. The presence of spiders not only affects the cleanliness of the car interior, but their excrement can also contaminate the interior, and some venomous spiders pose safety hazards. Chemical repellents work by releasing irritating gases to repel spiders, but they leave unpleasant odors, pollute the air inside the car, and have potential health risks.

[0003] This invention discloses a car repair skateboard capable of repelling mosquitoes, comprising a base, a support plate, a buffer cavity, casters, and a battery. The base has casters at its lower part and a support plate at its upper part, connected to the support plate via the buffer cavity. An insect repellent storage box is disposed between the buffer cavities, connected to the buffer cavities via a connecting pipe. The battery is installed on the front right side of the support plate, and a placement slot is provided on the front left side of the support plate. An inner cavity is formed inside the support plate, and a main guide pipe is located in the middle of the support plate, connected to the insect repellent storage box below. Branch guide pipes are connected to both sides of the main guide pipe.

[0004] Existing technologies for insect repellent in vehicles are not very targeted and are not very effective at repelling spiders. Summary of the Invention

[0005] The present invention aims to provide a pre-embedded low-power LED cold light system and control method for spider repellency in vehicles, so as to enhance the targeting of insect repellency and improve the repellency effect on spiders.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] This invention provides a pre-embedded low-power LED cold light system for spider avoidance in vehicles, comprising an LED cold light module, a power supply module, and a control module. The output terminal of the power supply module is connected to the input terminal of the LED cold light module, the output terminal of the power supply module is connected to the input terminal of the control module, and the output terminal of the control module is connected to the input terminal of the LED cold light module.

[0008] The LED cold light module uses LEDs with wavelengths in the range of 460nm to 480nm.

[0009] The LED lights are at least two in number, with a power range of 0.05W to 0.1W.

[0010] The power supply module includes a car battery and a DC-DC converter, wherein the car battery is connected to the LED cold light module and the control module respectively through the DC-DC converter.

[0011] The power supply module also includes a lithium battery pack, the power output terminals of which are connected to the input terminals of the LED cold light module and the control module, respectively.

[0012] The control module includes a light-sensing control module and a manual control module.

[0013] The light-sensing control module includes a light sensor, a voltage comparator, and a driver chip. The output terminal of the light tube sensor is connected to the non-inverting terminal of the voltage comparator, and the reference voltage is connected to the inverting terminal of the voltage comparator through a Zener diode. The output terminal of the voltage comparator is connected to the LED cold light module through the driver chip.

[0014] The manual control module includes a manual control switch and a timer. The manual control switch is connected to the LED cold light module through the timer.

[0015] The wires between the manual control switch and the LED cold light module are flexible wires, which are embedded in a waterproof encapsulation shell. The waterproof encapsulation shell is fixed to the embedded card holder, and a buffer rubber pad is provided on the surface of the embedded card holder.

[0016] This invention provides a control method for a pre-embedded low-power LED cold light system for spider avoidance in vehicles:

[0017] The light sensor in the light control module collects light information and generates a voltage signal, which is then compared with a preset voltage by a voltage comparator. When the light intensity is low, the voltage comparator outputs a drive signal to the LED cold light module through the driver chip.

[0018] When the user presses the manual control switch, the LED cold light module turns on and turns off after the set time.

[0019] The technical effects of this invention are as follows:

[0020] (1) This invention has strong repellency targeting and stable effect. It accurately targets the spider's avoidance characteristics and uses blue LED lights with a wavelength of 460nm-480nm, which can directly and significantly repel spiders, reducing the number of spiders inhabiting and weaving webs in the vehicle from the source. At the same time, through the design of light strip (5cm-20cm) or LED array, it can achieve full light coverage of the target area according to the spatial characteristics of the installation area in the vehicle, avoiding blind spots. Compared with a single light source or non-targeted wavelength light source, the repellency effect is more significant and lasting.

[0021] (2) This invention has the advantages of safety and environmental protection. It uses cold light physical repellency with a specific wavelength, without the release of chemical agents, thus avoiding pollution of the air inside the car and potential impact on human health. It will not cause spiders to develop drug resistance, and the repellency effect is stable for a long time.

[0022] (3) This invention features good concealment, strong protection, and does not affect the interior environment of the vehicle. The manual control switch extends to concealed locations such as the center console storage compartment and the inside of the door armrest. The flexible wire can flexibly adapt to the complex wiring environment inside the vehicle, making it easy to hide and install without damaging the original wiring layout and aesthetics. The wire is embedded in a polycarbonate waterproof enclosure with an IP65 rating. Combined with a surface anti-scratch coating, it can effectively resist the corrosion of condensation and dust inside the vehicle and protect the circuit safety. The embedded bracket adopts an elastic buckle structure and a buffer rubber pad, which can be quickly fixed to various interior positions, adapt to interior structural parts of different thicknesses, and ensures a firm installation while avoiding wear and tear on the interior.

[0023] (4) This invention has the advantage of low power consumption. The LED lights are strictly controlled within the power range of 0.05W-0.1W, minimizing energy consumption while ensuring the light-repelling intensity. The DC-DC converter converts the vehicle's 12V voltage to a stable 5V power supply, further optimizing power supply efficiency and reducing energy loss. The low power consumption design avoids putting an excessive burden on the vehicle's power supply, and will not affect the normal performance of the vehicle's battery even after long-term use.

[0024] (5) This invention features a simple structure, strong compatibility, and long service life. The whole system consists of an LED cold light module, a power supply module, and a control module. Each module has a clear function and smooth connection. The components are universally selected and highly reliable, which facilitates production assembly and subsequent maintenance. The overall system design is tailored to the complex working conditions of the vehicle environment, taking into account multiple requirements such as waterproofing, dustproofing, scratch resistance, and voltage adaptation. It can adapt to the interior structure and usage scenarios of different vehicle models. Compared with traditional external drive-avoidance devices, it has stronger stability, longer service life, and does not occupy extra space in the vehicle.

[0025] (6) The present invention has the advantages of stable and reliable power supply. It adopts a dual power supply mode with the car battery as the main power supply and the backup lithium battery pack as the auxiliary power supply. Under normal circumstances, the vehicle battery provides stable power supply. When the vehicle is turned off and the vehicle power is disconnected, the backup lithium battery pack automatically and seamlessly connects to provide power supply, ensuring that the system does not stop working during parking and avoiding spiders from taking advantage of the power outage.

[0026] (7) The present invention is flexible and convenient to control and highly intelligent. It integrates two modules: light-sensing automatic control and manual control. The light-sensing control module detects the light intensity inside the vehicle through a photoresistor. When the light intensity is lower than the preset threshold, the LED lights are automatically turned on and automatically turned off when the light is sufficient. No manual intervention is required, thus realizing intelligent and energy-saving operation. The manual control module is equipped with a push-button switch and an electronic timer, which not only meets the needs of active avoidance but also avoids the waste of electricity caused by forgetting to turn off the lights. The operation is convenient and controllable. Attached Figure Description

[0030] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0031] This invention provides a pre-embedded low-power LED cold light system for spider avoidance in vehicles, including an LED cold light module, a power supply module, and a control module. The output terminal of the power supply module is connected to the input terminal of the LED cold light module, the output terminal of the power supply module is connected to the input terminal of the control module, and the output terminal of the control module is connected to the input terminal of the LED cold light module.

[0032] The LED cold light module uses LEDs with wavelengths in the range of 460nm to 480nm. There are at least two LEDs, with a power range of 0.05W to 0.1W.

[0033] The power supply module includes an automotive battery and a DC-DC converter. The automotive battery is connected to both the LED cold light module and the control module via the DC-DC converter. The power supply module also includes a lithium battery pack, the power output of which is connected to the inputs of both the LED cold light module and the control module.

[0034] The control module includes a light-sensing control module and a manual control module. The light-sensing control module includes a light sensor, a voltage comparator, and a driver chip. The output of the light sensor is connected to the non-inverting input of the voltage comparator, and the reference voltage is connected to the inverting input of the voltage comparator via a Zener diode. The output of the voltage comparator is connected to the LED cold light module via the driver chip. The manual control module includes a manual control switch and a timer. The manual control switch is connected to the LED cold light module via the timer.

[0035] The wires between the manual control switch and the LED cold light module are flexible wires. The flexible wires are embedded in a waterproof encapsulation shell, which is fixed to an embedded card holder. The surface of the embedded card holder is equipped with a buffer rubber pad.

[0036] This invention provides a control method for a pre-embedded low-power LED cold light system for spider avoidance in vehicles:

[0037] The light sensor in the light control module collects light information and generates a voltage signal, which is compared with a preset voltage by a voltage comparator. When the light intensity is low, the voltage comparator outputs a drive signal to the LED cold light module through the driver chip. When the user presses the manual control switch, the LED cold light module turns on and turns off after the set time.

[0038] The following is a detailed description of a pre-embedded low-power LED cold light system for spider avoidance in a vehicle according to the present invention.

[0039] This invention discloses a pre-embedded low-power LED cold light system for spider repellency in vehicles, comprising an LED cold light module, a power supply module, and a control module. The LED cold light module uses LED lights. Since spiders exhibit a strong aversion to blue light with wavelengths between 460nm and 480nm, the LED lights used in this invention have wavelengths in the 460nm to 480nm range. This invention uses at least two LED lights; however, to achieve a better spider repellency effect, ten LED lights are used in this embodiment. To meet low power consumption requirements, the LED lights selected in this invention have a power rating between 0.05W and 0.1W. Depending on the spatial characteristics of the installation area, the LED lights are designed as LED strips (5cm-20cm in length) or LED bead arrays to ensure that the light covers the target area.

[0040] The power supply module uses a 12V automotive battery, which is converted to 5V via a DC-DC converter to provide a stable power supply for the LED lighting module and control module. The power supply module also uses a backup lithium battery pack, which supplies power to the LED lighting module and control module when the vehicle is off and the vehicle's power supply is disconnected, preventing system power outages during parking.

[0041] The control module includes a light-sensing control module and a manual control module. The light-sensing control module includes a light sensor, a voltage comparator, and a driver chip. The light sensor detects the light intensity inside the vehicle. When the light intensity is below a preset threshold, the LED cold light module is automatically activated; when the light is sufficient, it is automatically deactivated. Specifically, the photoresistor in the light sensor senses the light intensity. When the light intensity changes, the resistance of the photoresistor changes, and the output voltage changes accordingly, decreasing as the resistance of the photoresistor increases. The voltage signal output from the light sensor is sent to the non-inverting input of the voltage comparator. The reference voltage is input to the inverting input of the voltage comparator through a Zener diode. The voltage comparator compares the voltage input from the light sensor with the voltage input to the inverting input. When the voltage input from the light sensor is less than the voltage input to the inverting input, the voltage comparator outputs a high level to the driver chip. The driver chip then outputs a stable current to the LED, illuminating the LED. In this embodiment, the driver chip uses an IRFZ44N signal.

[0042] The manual control module includes a manual control switch and a timer. One end of the manual control switch is connected to the power supply module, and the other end is connected to the LED light via the timer. The manual control switch uses a push-button structure. The first press connects the circuit, activating the LED light module and keeping it constantly lit. A second press disconnects the circuit. The timer is an electronic timer with a preset duration. When the preset duration is reached, the timer's internal contacts automatically open, cutting off the power supply circuit between the power supply module and the LED light module, stopping the LED light module from operating.

[0043] The manual control switch extends via a wire to a concealed operating location within the vehicle (such as the center console storage compartment or the inside of the door armrest), allowing the owner to manually start and stop the device as needed. The wire between the manual control switch and the LED cold light module is a flexible wire, which can flexibly adapt to the complex wiring environment inside the vehicle, facilitating concealed installation without affecting the original wiring layout. The flexible wire is embedded in a waterproof enclosure made of polycarbonate material with a scratch-resistant coating and an IP65 rating, preventing damage to the circuitry from condensation and dust inside the vehicle. The waterproof enclosure is fixed to an embedded bracket with a flexible snap-fit ​​structure, allowing for quick and easy attachment to internal supports in the center console, door trim panel layers, and other locations, while also accommodating interior structural components of varying thicknesses. The surface of the embedded bracket is equipped with a cushioning rubber pad.

[0044] The following describes in detail the control method of a pre-embedded low-power LED cold light system for spider avoidance in a vehicle according to the present invention.

[0045] The light sensor in the light control module collects light information and generates a voltage signal, which is output to the non-inverting input of the voltage comparator. The reference voltage is input to the inverting input of the voltage comparator through the Zener diode, thus providing the preset voltage. When the light intensity is low, the photoresistor in the light sensor is large, and the output voltage of the light sensor is small. When the output voltage of the light sensor is less than the preset voltage, the voltage comparator outputs a high level to the driver chip, and the driver chip outputs a stable current to the LED cold light module, illuminating the LEDs in the LED cold light module.

[0046] When the user presses the manual control switch, the circuit between the power supply module and the LED cold light module is connected, the LED in the LED cold light module lights up, and turns off after the set time is reached. The set time is set by a timer.

[0047] The beneficial effects of the present invention are described in detail below.

[0048] This invention features highly targeted and stable repellency. It precisely targets spider repulsion characteristics, employing blue LED lights with a wavelength of 460nm-480nm, directly and significantly repelling spiders and reducing their presence and web-building activities inside vehicles. Furthermore, through a strip-style (5cm-20cm) or LED array design, it achieves full light coverage of the target area based on the spatial characteristics of the installation area within the vehicle, avoiding blind spots. Compared to single light sources or non-targeted wavelength light sources, the repellency effect is more significant and longer-lasting.

[0049] This invention has the advantages of safety and environmental protection. It uses cold light of a specific wavelength for physical repellency, without releasing any chemical agents, thus avoiding pollution of the air inside the vehicle and potential impact on human health. It also does not cause spiders to develop drug resistance, and the repellency effect is stable over a long period of time.

[0050] This invention offers excellent concealment, strong protection, and minimal impact on the vehicle's interior environment. The manual control switch extends to concealed locations such as the center console storage compartment and the inside of the door armrests. The flexible wiring adapts flexibly to complex wiring environments within the vehicle, facilitating concealed installation without disrupting the original wiring layout or aesthetics. The wiring is embedded in a polycarbonate waterproof enclosure with an IP65 rating and a scratch-resistant coating, effectively resisting condensation and dust corrosion, protecting the circuitry. The embedded mounting bracket uses a flexible snap-fit ​​structure and cushioning rubber pads, allowing for quick and easy installation in various interior trim locations, adapting to different thicknesses of interior structural components, ensuring a secure installation while preventing wear and tear on the interior.

[0051] This invention features low power consumption. The LED lights are strictly selected and controlled within the power range of 0.05W-0.1W, minimizing energy consumption while ensuring sufficient light-blocking intensity. A DC-DC converter transforms the vehicle's 12V voltage into a stable 5V power supply, further optimizing power efficiency and reducing energy loss. The low-power design avoids overburdening the vehicle's power supply, ensuring that even long-term use will not affect the vehicle's battery performance.

[0052] This invention features a simple structure, strong compatibility, and long service life. It consists of an LED cold light module, a power supply module, and a control module. Each module has a clearly defined function and seamless integration. The components are universally compatible and highly reliable, facilitating production, assembly, and subsequent maintenance. The overall system design is tailored to the complex operating conditions of the vehicle environment, addressing multiple requirements such as waterproofing, dustproofing, scratch resistance, and voltage compatibility. It can adapt to the interior structures and usage scenarios of different vehicle models. Compared to traditional external obstacle avoidance devices, it offers greater stability, a longer service life, and does not occupy additional space inside the vehicle.

[0053] This invention has the advantage of stable and reliable power supply. It adopts a dual power supply mode with the car battery as the main power supply and the backup lithium battery pack as the auxiliary power supply. Under normal circumstances, the car battery provides stable power supply. When the vehicle is turned off and the car power is disconnected, the backup lithium battery pack automatically and seamlessly takes over the power supply, ensuring that the system does not stop working during parking and preventing spiders from taking advantage of the power outage.

[0054] The present invention features flexible and convenient control with a high degree of intelligence. It integrates two modules: automatic light-sensing control and manual control. The light-sensing control module detects the light intensity inside the vehicle through a photoresistor. When the light intensity is below a preset threshold, the LED lights are automatically turned on and automatically turned off when the light is sufficient, without the need for manual intervention, thus achieving intelligent and energy-saving operation. The manual control module is equipped with a push-button switch and an electronic timer, which not only meets the needs of active avoidance but also avoids the energy waste caused by forgetting to turn off the lights. It is convenient and controllable to operate.
