Detailed Description

The present invention will now be described more fully and clearly with reference to the accompanying drawings.

Referring to fig. 1 to 4, an active anti-collision device for an automobile side door comprises a control induction mechanism and a mechanical switch mechanism which are arranged on an automobile door at a driving side of an automobile, wherein the control induction mechanism comprises a pressure sensor 1 arranged on a handle at the inner side of the automobile door, a radar sensor 2, an infrared sensor 3 and an audible and visual alarm 4 which are arranged on the outer side wall of the automobile door, and a controller 5 is arranged in a cavity 6 at the lower end of the automobile door; the mechanical switch mechanism comprises an electromagnet 7 which is arranged in a cavity 6 and on one side of the controller 5 close to the free end of the car door, a fixed block 8 is arranged on the other side of the electromagnet 7, an inserted rod 9 is inserted into the fixed block 8, a spring 10 is sleeved outside the inserted rod 9, one end of the spring 10 is connected with the fixed block 8, the other end of the spring 10 is connected with a pressing plate 11 fixed on the inserted rod 9, and a slot 12 is arranged at the position of the car body corresponding to the inserted rod 9.

The controller 5 is a single chip microcomputer.

The inserted bar 9 is made of iron.

The control circuit is a conventional circuit.

The utility model discloses a theory of operation does:

when the inside passenger of automobile body held interior handle and prepared the door of opening, interior pressure sensor 1 on the handle is triggered, pressure sensor 1 is signal transmission to controller 5, controller 5 passes through radar sensor 2 and infrared sensor 3 can detect whether there is vehicle or pedestrian outside the door, when the door does not have vehicle or pedestrian outward, controller 5 makes electro-magnet 7 continue to keep the on-state, inserted bar 9 is attracted by electro-magnet 7 and is retracted in cavity 6, and through clamp plate 11 compression spring 10, can normally open the door this moment.
