Cigarette lighter solution
Cigarette lighters have become one of the must-have items for cars. The cigarette lighter can automatically complete the heating and ejecting actions, and the user can use it to light the cigarette after taking it out. It improves the intelligence and comfort level of the vehicle, simplifies the operation process for the driver to light a cigarette, greatly avoids risks and improves user experience. With the continuous advancement of modern electronic technology and the vigorous development of the automobile industry, power performance is no longer the only indicator for measuring automobiles. Many factors such as reliability, comfortable driving experience, and intelligent networking have played a considerable role in the evaluation of automobiles.
1. Safe use of cigarette lighter
The mechanical performance, stability, fatigue resistance and other factors of the cigarette lighter greatly affect the safety and reliability of the car. If the continuous heating time is too long or the ejection force is insufficient, it will cause problems in the body circuit or even a fire. Relevant literature also records accidents such as transmission failure and other accidents caused by the abnormal structure and ejection of the cigarette lighter, which caused problems with the body circuit. It can be seen that a reliable and durable pop-up cigarette lighter is the basis and premise of car safety, comfort and intelligence.
The safety of car cigarette lighters has already attracted widespread attention. The Japanese Industrial Standard JIS D 5807, the American Society of Motor Vehicle Engineers standard SAE/USCAR-4, and various automobile manufacturing companies have related product standards for them. Relevant departments of the Chinese government have also compiled the QC/T 415-2006 specification for car cigarette lighters, which strictly defines and regulates the pop-up force, heating time, and plug-in performance of the cigarette lighter.
2.The technical principle of the cigarette lighter program
Generally speaking, cigarette lighters are mainly used in places where open flames are rejected, such as factories, workshops and other places that need to light cigarettes, so they can only be done with a cigarette lighter. In addition, the car cigarette lighter can also be equipped with a car inverter, which can convert the 12V, 24V or 48V DC power on the car into 220V/50Hz AC power supply, which can be used by ordinary electrical appliances. For example, mobile electronic devices can be charged. It is best to use a split type for the vehicle-mounted inverter, and the power of the electrical appliances used is limited to less than 150W, and the output current will not be greater than the current of the battery. The cigarette lighter socket is an electronic device that is similar to a multi-hole power socket for household electricity. It is connected to a car power supply through a plug, and then leads to multiple cigarette lighter sockets. The cigarette lighter socket is very useful for car owners who often use car electronics.
3. Scheme design of low-voltage DC charging cigarette lighter
The low-voltage DC rechargeable cigarette lighter is a new type of environmentally friendly cigarette lighting tool that uses electric energy. It changes the unsafe factors that exist when the original lighter uses gas or gasoline, and avoids the unsafe operation of the original lighter that is difficult to refill with gas or gasoline. convenience. The emergence of low-voltage DC cigarette lighters has shown a broad market prospect.
The working principle of the low-voltage DC cigarette lighter is that the rechargeable lithium battery and the sheet-shaped metal electric thermal conductor are turned on through the sliding switch, button switch or signal switch installed on the low-voltage DC cigarette lighter housing, so that the rechargeable battery Discharge to the metal electric heat conduction sheet, under the action of a large current, the metal electric heat conduction sheet will instantly heat up and turn red, thus igniting combustible items such as cigarettes.
The main features of the cigarette lighter: ①It can be charged through the USB interface, and can also be charged through a charger with similar charging data. The rechargeable battery of the cigarette lighter can be repeatedly charged and discharged 300 times, and has a long service life. ② charging time 1.5 ~ 3 h. After one full charge, it can be discharged 30 to 60 times based on the working time of 5 s each time. ③ Windproof and light cigarettes. ④ Light cigarette silently. ⑤ No filling of gas and liquid fuel is required, and the safety performance is good. ⑥Small size, flexible appearance design, can be made into various shapes and sizes according to user needs.
The low-voltage direct-current cigarette lighter uses battery charge and discharge as energy, and is safer, more convenient, and more environmentally friendly than traditional lighters, with a simpler structure and fewer failures. The universal USB interface is more convenient to charge, and the voltage is also a uniform DC 5 V. There are no disadvantages such as gas lighters with different air pressures and gas purity, cotton oil lighters with different oil quality, difficult to match, and certain dangers. It also overcomes the difficulty of using traditional lighters due to temperature and altitude. Dozens of cigarettes can be lit on a single charge. The newly developed products can also ignite gas, candles and spices, and can completely replace traditional lighters. In particular, the battery can be repeatedly charged and discharged hundreds of times, which has a longer service life than traditional lighters. At the same time, there is no open flame, and the safety is greatly improved.
4. Structure and function of low voltage DC cigarette lighter
The use of printed circuit board technology simplifies the overall structure, makes the performance more stable, and also reduces the volume of the low-voltage DC cigarette lighter. The metal electric thermal conductor, the switch, and the rechargeable battery are connected in series through the traces on the printed circuit board. When the switch is turned on, the rechargeable battery conducts the metal electric thermal conductor through the traces on the printed circuit board, making the metal electric thermal conductor red and hot. . Make full use of the rechargeable battery and the printed circuit board (the printed circuit board can be double-sided or even multi-layer board), which can facilitate the expansion of functions. The existing extended functions of cigarette lighters in the market are: low-voltage DC cigarette lighter with shaver, low-voltage DC cigarette lighter with flashlight, low-voltage DC cigarette lighter with USB storage function, with charging Low-voltage DC cigarette lighter with treasure function, low-voltage DC cigarette lighter with solar charging, low-voltage DC cigarette lighter with Bluetooth device, etc., the extended function is unlimited.
5. Advantages of USB cigarette lighter solution
The use of USB interface makes charging more international and simple. The USB charging interface is connected in series with the rechargeable battery through the wiring on the printed circuit board, and can be charged when the power is turned on. At present, smart phones are charged by USB interface, and the mobile phone charger can be fully used to charge the low-voltage DC cigarette lighter, which is more conducive to environmental protection.
Using a lithium battery as an energy storage is more environmentally friendly. Using a lithium battery that can be repeatedly charged and discharged and has a large energy storage as an energy source can make the low-voltage DC cigarette lighter smaller and more environmentally friendly.
Using a specific chip to manage the power of the cigarette lighter is more intelligent. Use a specific chip to control charging and discharging, and automatically cut off after discharging for a certain period of time to protect the battery and products; control the redness time of the metal electric thermal conductor, and automatically disconnect the power supply after charging until the battery is saturated. , which is more secure. At the same time, you can set multi-function chips, such as the display of remaining power, charging other electrical appliances, enabling the airflow switch, protection when short circuit, and protection when the temperature is too high.
The use of metal electric heat conduction sheets avoids the disadvantages of aging and easy damage of electric heating wires. The metal electric heat conduction sheet has the characteristics of high temperature, compact structure, strong shape plasticity, high strength, stable support, strong reliability, long service life, etc., and the cost does not increase, and it is more beautiful and durable as a whole.
