Background
With the development of society, the vehicle becomes a necessary product for people to go out, and all kinds of cars are distributed in streets and alleys, so that convenience is brought to people, more life hazards are brought to people, and how to protect the safety of pedestrians in going out becomes the most headache of manufacturers in various countries and automobile fields, but has to be paid attention to and needs to be solved urgently.
In order to solve the problem of pedestrian protection, particularly, when an automobile is in collision with a pedestrian carelessly in the driving process, the head of the automobile body firstly touches the legs of the human body to contact, the pedestrian turns over along the trend, the head directly bumps against an engine cover of the automobile, a windscreen wiper is arranged at the root of the engine cover, the head of the pedestrian is very likely to hit a rotating shaft of the windscreen wiper rightly, the windscreen wiper shaft is formed by processing a right steel bar with the diameter of 6-14mm, and the steel bar is inserted into the head of the human body like a nail to cause fatal injury to the pedestrian. In order to prevent such accidents, the wiper blade may be broken or contracted and sunk under a certain impact force. Therefore, the injury to the head of a human body caused by collision can be reduced, and the injury index HIC of the head of the human body is reduced to 1700 or even below 1000. Thereby ensuring the safety of the pedestrians.
The requirements of various vehicle types in various countries on collision force are slightly different, and reference can be made to GB/T2450-2009 pedestrian collision protection of automobiles.
The existing pedestrian protection mode comprises a hidden pedestrian protection mode and a support seat fracture mode. Hidden pedestrian protection is like the car ventilating hood decorative board for pedestrian protection that patent number 201120337431.9 that the jeli car applied for 2011.09.09 discloses, and its main technological effect is through the decorative board thereby play hidden effect to the wiper rotation axis, but this mode receives the vehicle body structure's limitation great, and most motorcycle types arrange the difficulty, and analog analysis is comparatively difficult, and is poor with actual conformance, needs many times to test the adjustment design scheme.
The supporting seat fracture mode is like last hai general car in the broken windscreen wiper bush of a kind of application of 9 months 30 days of 2008 and the wiper that constitutes by it, its fracture area through setting up realizes the pressurized fracture function of windscreen wiper bush, but the supporting seat fracture is to different motorcycle types, different link structure, required breaking force is different, need the die sinking again, because the supporting seat generally adopts die mould, the size is great, causes the development cycle length, and the development cost is high.
