Car Door Soft Close Industry News
In fact, with the development of automobile technology, many cars now have electric suction doors, especially high-end cars. The advantage of electric suction doors is that it saves effort to close the door, and the door will automatically close with a single touch. This function is mainly for the convenience of the elderly and children, because their strength is relatively small.
I believe that every car owner has such an awkward experience: Whenever it rains, or when we carry heavy objects, we often can't free our hands to close the car door. As a result, everyone always closes the car door in a variety of awkward postures, but because they are worried that the car door is not closed tightly, they have to close it again deliberately.

In contrast, high-end imported models with electric suction doors don't have to spend a lot of time. Electric suction doors are common in luxury cars. When the door is not closed, the door will automatically close until it is completely closed. For this reason, the car owner only needs to elegantly bring the car door lightly to close the car door easily.
Although electric suction doors are extremely convenient to use, most consumers have no choice but to stay away from the high prices of high-end imported cars. As the general public, they must all want a luxurious ride experience and advanced car black technology. More importantly, they also need a down-to-earth price.
The cheapest cars with electrified suction doors are also priced at more than 800,000 yuan, such as Mercedes-Benz and BMW. Compared with many luxury models with electric suction door technology, what is heartwarming is that there are now many in the price range of 9.78-15.78 million, which is almost only the price range of an ordinary A-class car. Let customers also enjoy the configuration of high-end business cars at affordable prices, which is a perfect combination of technology, quality and cost-effectiveness.
However, Dongguan Kaimiao Electronic Technology Co., Ltd. mainly has the following technological innovations in the development of automotive intelligent electric suction door systems: Hall detection and signal processing are used to effectively identify the various states of the door lock mechanism in real time. Using a small drive motor, matching a large ratio transmission deceleration system, release sufficient suction power. The swing arm type forward and reverse clutch mechanism is adopted to safely and reliably realize the power separation switch. Adopt clever buffer type clutch cable mechanism to effectively prevent impact and ensure the long life of the electric suction door lock. Combined with an effective electronic software control system, it promotes the safe and reliable use of products.

At present, the technical advantages of the automotive intelligent electric suction door system developed by our company mainly include the following aspects:

1. The door lock state detection is sensitive, covering all states; Hall non-contact sensing, effectively avoiding the short life problem of mechanical switches, and the product is more reliable.

2. The swing arm type forward and reverse clutch mechanism realizes the function of emergency door opening, and the product is safer.

3. The impact clutch cable mechanism effectively isolates the impact of manual closing of the door lock, and the life of the electric suction is significantly improved.

4. The logic control of the secondary pull-in, combined with the overload protection, will prompt the user with the anti-pinch function during the automatic closing process. The experience is humanized and safer to use.

5. The product adopts modular design and layout, and integrates the controller and the driver. It has a compact structure and strong adaptability, which is conducive to the layout of the car body and the promotion and use of multiple models.

6.Through multiple circuit optimizations, the current of the smaller whole machine after sleep is controlled to be below 0.6mA (usually 1mA); it effectively reduces the standby power consumption of auto control products. At present, the company has applied for intellectual property protection since the development of automotive intelligent electric suction door system technology, including: invention patents: 4; utility model patents: 11; software copyrights 3.
For a long time, electric suction doors are only configured on a few imported models. Only a few joint venture manufacturers have mastered the main domestic technology, but the existing technology is mainly in the realization of primary functions, which tends to be safer, more humane, and there is a huge room for improvement in intelligent technology. At the same time, the new manufacturing technology has further ensured the platformization and popularization of this new technology. This will also push the car door lock system technology into a new epoch of intelligence.
At present, the intelligent electric suction door system of our company has gradually transformed into the market and realized profits. Among them, the mass-produced application models include: Nissan X-Jun, Nissan Qashqai, Nissan Loulan, Infiniti, Lexus RX570, GAC Trumpchi GS4/GS5/GS8, Guangben 2VG, Guangben 2LZ. And gradually introduce Volkswagen series models, GM series models, Ford series models, and Audi series models. At the same time, the Volvo models and Tesla models that are under planning to develop.
