Discussion on the Solution of Air Tightness Detection of Electric Bicycle Display Screen

Electric bicycle display screen is also called electric bicycle instrument panel. The display screen of electric bicycle generally displays the current battery power or battery voltage, vehicle speed, driving mileage and time, fault information, etc. you can see the operation of electric bicycle at any time. The internal circuit of electric bicycle display screen belongs to electronic products, and electric bicycles are generally used outdoors, often driving in the rain or parking outdoors.Therefore, the display screen of electric bicycle must have waterproof performance higher than IP67 waterproof and dustproof grade, so as to ensure that the display screen of electric bicycle can operate normally in any environment. Therefore, the manufacturer will test the air tightness of the instrument before leaving the factory. What is the solution for the air tightness test of the display screen of electric bicycle.

Discussion on the Solution of Air Tightness Detection of Electric Bicycle Display Screen 1

The traditional detection method adopts the water detection method (bubble detection method), the result is very intuitive, but the detection accuracy and efficiency are low, and there are many electronic components in the electric vehicle instrument. If water enters the instrument, it will directly damage the internal electronic components, so the water detection method is rarely used. For electronic products, dry compressed air (which will not cause secondary damage to the product) is widely used as the detection medium to detect the air tightness of the display screen of electric bicycle. The detection instrument used in the air tightness detection solution of electric bicycle display screen is air tightness detector.

According to the product shape, goer technology has made a profiling mold according to the product shape, and placed the product in the air tightness detection mold of the electric bicycle display screen. The air tightness detector of the electric bicycle display screen will fill the mold with quantitative compressed air, The air tightness detection equipment of electric bicycle display screen detects the change of compressed air in the mold in real time to judge whether the product has leakage.

The specific waterproof detection process of the air tightness detection solution for the display screen of the electric bicycle is as follows: connect the customized detection fixture to the air tightness detection equipment, set the test parameters according to the waterproof level to be tested and other requirements, and then connect the air tightness detector equipment and the test tooling to the air source and power supply respectively, The air tightness detection and sealing test of the display screen of the electric bicycle can be started. The instrument will automatically determine whether the product is OK or ng according to the set parameters.

How Can the Life and Brightness of LED Display Screen Be Improved
LED display screen is widely used in daily life, such as squares, gymnasiums, hotels, supermarkets, etc. wherever you can see public places, you can see the extensive use of LED display screen! How to make the service life and brightness of LED reach the standard of satisfactory use is a meaningful topic! To maintain long life and high brightness of LED display screen, the problems to be solved are: power supply, LED light source, heat dissipation and three key technologies. How to improve the service life and brightness of LED display?1. Power supplyThe primary requirement of power supply is high efficiency. For products with high efficiency, if the heating is low, the stability must be high. Generally, there are two schemes of isolation and non isolation in the power supply. The isolation volume is too large and the efficiency is low. Many problems will arise in use and installation, which is not as promising as the market prospect of non isolation products. Here we mainly discuss the non isolation drive scheme.2. LED light sourceThe chip is placed on the pins, and the heat energy passes through the silver foot to directly generate the tropical parts generated by the chip nodes. The simultaneous interpreting technology is qualitatively different from the traditional direct insertion products and the traditional patch products, and the temperature of the chip nodes does not accumulate, thereby ensuring the good usability of the lamp beads, ensuring the long life of the lamp beads and low light decay. Although the traditional chip products can connect the positive and negative electrodes through the gold wire of the chip, they also connect the heat generated by the chip to the silver foot through the gold wire. The heat and electricity are conducted by money. The long time of heat accumulation will directly affect the service life of LED display beads.3. Heat dissipationIn consideration of heat dissipation, we separate the heat dissipation of LED light source lamp beads and power supply without interference, so as to ensure the rationality of heat dissipation. There are three ways of heat conduction: convection, conduction and radiation. In a closed environment, convection and conduction are less likely to be realized, and heat is radiated through radiation, which is the focus of lamp beads.LED display screen is widely used in daily life, such as squares, gymnasiums, hotels, supermarkets, etc. wherever you can see public places, you can see the extensive use of LED display screen!
