Audi A4L 2015-2017 Universal Automatic Smooth Car Door Closer, Automatic Car Soft Close Doors
Why electric suction doors can prevent anti-clips?
The electric suction door is a comfortable and safe configuration commonly used in luxury cars.When the door is not closed, The door will be automatically absorbed. The electric suction door has many conveniences to provide the owner with more comfortable driving experiences.
However, the traditional electric door has another important hidden danger.Easy to hurt the hand, In recent years the news of the electric suction door clips is frequent .Here's an example :
Last February 26th,Ms. schweineberg, who lives in North State ,she get out of the way to another car,She stood on the door of her car. Hand on the handle of the door.Because it's very narrow, She closed the door with only one sewn. The thumb was inadvertently placed in the door. Because the door is close to the closed state, the electric suction device is started.The great force pinched the thumb directly. And the clipped part has been completely deformed,Unable to sew to continue to use ,Ms. Schweineberg said she could still feel the phantom limb pain until today. The hallucinations of numbness of the thumb can often be felt.
What is the suction of an ordinary electric suction door?
| Why the clamp hand of the electric door is so powerful?At this time, we should dissect the principle of its structure.The electric suction door controls the closing of the door through the power supply and breakage. A doorframe (or the edge of a door plate) equipped with an electromagnetic coil,When the door is opened, there will be electric current passing through the coil. Thus the electromagnetic field is formed because of the magnetic force. When the door closes closer to the door frame ,The door will be automatically sucked up. |
| Manufacturers say that when you want to close the door completely, you need to use a lot of strength,The door "dump" dozens of centimeters to shut down ,The path of the door is too short because the door is closed.So more force is needed to keep the door closed.The power of the traditional electric suction door is about 600 cattle(61 kilograms ),If it is trapped by an electric suction door ,It is equivalent to being placed on the finger by an adult with iron shoes on one foot. |
KaiMiao Group How to realize anti-clamp in auto automatic suction system?
The Holzer sensor is used for the anti-clamp electric suction door,Can detect the rotational speed of the auxiliary motor ,And projected onto the electric suction door With a highly customizable function ,It can also accurately detect the magnitude of the current in the electronic circuit. When the current exceeds the threshold in the loop ,An instruction will be sent to stop / reverse the motor.(That is when there are foreign objects & interference etc. )
Through scientific research test ,The power of the automatic suction system is around 150-200 cows(15-20 kilograms ),There is a slight pain in the adult finger.
Automatic suction system after installation,The door is only 6 millimeters away from the full lock position.(that is semi lock position) ,The lock began to absorb ,This distance is generally smaller than the finger thickness of adult men. That is to say, it is not easy to enter the door at this time. And if I had put my hand in before that, The door can't reach the half lock.
Automatic suction system,When the door reaches half lock, time zone is different from other products in the market. The door tightened and sounded slowly ,This response time is enough for fingers to be caught and not clamped.To some extent, it prevents the pinch of the hand.
For R & D hand function,Volunteers at different ages were tested. It is found that the hand of a 20-50 year old adult has slight pain.The hand pain of adult women increased slightly at this stage.Adolescents over the age of 15 are similar to women with mild pain.
At the beginning of R & D, sensors, speed control, braking, emergency disposal and other factors. Really do the anti-clip design ,It is also a historic change and breakthrough in the history of automotive automatic suction system.
