Embodiment 1

[0032] The anti-collision head device of this car door is arranged on the car door frame 1, is used for alleviating the impact force that the passenger's head hits the car door frame 1 when getting in and out of the car. The anti-collision head device of the automobile door comprises an air bag 2 , an inflation and deflation mechanism 3 , a detection unit 4 and a control unit 5 . Such as image 3 As shown, the control unit 5 is connected to the inflation and deflation mechanism 3 and the detection unit 4 respectively, and the control unit 5 can analyze and process the electrical signal sent by the detection unit 4 and output a control signal to control the working state of the inflation and deflation mechanism 3 .

[0033] Specifically, as figure 1 and figure 2As shown, the airbag 2 is arranged on the top of the door frame 1, the airbag 2 is fixed with a fixing plate 6, and the fixing plate 6 is provided with an installation hole, and the airbag 2 is fixedly connected to th...

Embodiment 2

[0041] The technical solution in the present embodiment is basically the same as the technical solution in the first embodiment, the difference is that in the present embodiment, the position sensor is a displacement sensor capable of detecting the opening width of the car door, and the control unit 5 is used to receive the transmission from the displacement sensor. The door opening width signal is compared with the preset value in the control unit 5, the inflation and deflation mechanism 3 is controlled to inflate the air bag 2 when the door opening width is greater than the preset value, and the inflation and deflation mechanism is controlled when the door opening width is smaller than the preset value 3 pump air to air bag 2. The use of displacement sensors is used to solve sliding doors.

Abstract

The invention provides an anti-collision head device of an automobile door and an anti-collision method thereof, belongs to the technical field of automobiles, and solves the technical problems of unsatisfactory protection effect and the like of the existing anti-collision head device. The anti-collision head device of an automobile door comprises an air sac, an inflation / deflation mechanism and a detection unit; and the automobile body is also provided with a control unit. The anti-collision method comprises the following steps that: A, the door is opened, and the control unit continuously detects a door opening degree signal; B, the control unit compares the door opening degree signal with a preset opening degree value; if the door opening degree signal is greater than the preset opening degree value, the control unit inflates air into the air sac; C, after the preset inflation time, the inflation is stopped; D, the door is pulled back, the door opening degree is gradually reduced, and the control unit exhausts air in the air sac when the door turning angle is less than or equal to the preset opening degree value; and E, the door is closed, a lock sensor sends a door lock electric signal to the control unit, and the exhaust is stopped. The device provided by the invention has the advantages of good safety perforamnce, accurate control, low energy consumption and the like, and is easy to dismantle.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to an anti-collision head device of an automobile door and an anti-collision method thereof. Background technique [0002] The height of the door frame of a car, especially a car, is generally low, lower than the height of a normal person, so people need to lower their heads when entering or leaving the car door to prevent their heads from hitting the door frame. In addition, when the light is dark at night, it is sometimes difficult to judge the position of the door frame, and you will hit your head when you go in and out. For this reason, an anti-collision device is badly needed. [0003] At present, some cars on the market are designed to prevent the paint from falling off or being damaged when the door accidentally hits the surrounding objects when the door is opened, and even to avoid the same situation in some parts of the car body. Anti-collision strip: The anti-collision ...
