Abstract
The invention relates to a motor vehicle air-conditioning air inlet duct structure suitable for protecting pedestrian's head during impact. The structure comprises an upper plate structure which is connected with a bottom part of a front windshield of the motor vehicle, a lower plate structure which is connected with a fire protection wall in a cabin of the motor vehicle and an intermediate plate structure which connects the upper plate structure and the lower plate structure. The upper plate structure, the intermediate plate structure and the lower plate structure are fixedly connected with each other to form the air-conditioning air inlet duct structure, wherein at least part of a cross section of the air-conditioning air inlet duct structure is Z-shaped. Because the air-conditioning air inlet duct structure with a Z-shaped cross section is provided in the invention. Accordingly, dynamic stiffness and modal requirements of a traditional structure are realized and acceleration of the head impact acceleration of a pedestrian is effectively reduced, thereby harm to the head of the pedestrian is reduced. By optimizing the traditional structure, when the head of the pedestrian collides with the bottom part of the front windshield of an automobile, an impact acceleration of the air-conditioning air inlet duct structure to the head of the pedestrian is reduced, and harm value done to the head of the pedestrian is effectively reduced.

Particularly, principle of work of the present invention and working process are:
A kind of motor vehicle air conditioning air inlet duct structure that is applicable to pedestrian protecting head impact of the present invention, is made up of three-piece metal part, comprises described upper plate structure 10, intermediate plate structure 20 and lower plate structure 30.The cross section of three structures that metal sheet forms is zigzag, as shown in the air-conditioning air inlet duct structure 1 in Fig. 4.And traditional air-conditioning air inlet duct structure is made up of two metal pieces, cross section is " 7 " font.Angle between three metal pieces of the present invention is preferably 35～55 degree.
In the time that self-propelled vehicle adopts air-conditioning air inlet duct structure of the present invention, if pedestrian head strikes near front windshield glass 2 bottoms, can there is rapidly conquassation in the Z-type cross section structure between three metal pieces of the present invention with angle, absorb pedestrian head Impact energy, thereby reduce the injury values of pedestrian head.By sunykatuib analysis, known the present invention can reduce by 20% than traditional air-conditioning air inlet duct structure in pedestrian head injury values, and effect is remarkable.
Referring to Fig. 3, in the upper plate structure 10 of described air-conditioning air inlet duct, in order to coordinate Windshield, leading portion 100 width of the upper plate structure 10 of air-conditioning air inlet duct are 20～40mm, be preferably in the present embodiment 30mm, and leading portion 100 and the horizontal sextant angle α of upper plate structure 10 is 20～30 degree, as shown in Figure 3.Further, on described air-conditioning air inlet duct, the stage casing 200 of plate structure 10 is level angle, clashes into energy herein in order fully to absorb pedestrian head, and the cross-sectional length in this stage casing 200 is 80～120mm, and the present embodiment is preferably 100mm.
Referring to Fig. 3, in the lower plate structure 30 of described air-conditioning air inlet duct, the leading portion 400 of lower plate structure 30 is connected by solder joint with the leading portion of intermediate plate structure 20 equally.The back segment 600 of lower plate structure 30 is connected by solder joint with self-propelled vehicle front deck fireproof brickwork 3, and in pedestrian head knockout process, this lower plate does not deform substantially.In order to meet body in white dynamic stiffness and mode requirement, the cross-sectional length of the back segment 600 of lower plate structure 30 is 80～120mm, is preferably 100mm.In pedestrian head knockout process, this lower plate structure 30 does not deform substantially.Simultaneously for after allowing pedestrian head clash into, upper plate structure 10 and intermediate plate structure 20 have sufficient space that conquassation occurs fully in the vertical direction, the stage casing of the lower plate structure 30 of described air-conditioning air inlet duct and lower plate structure 30 leading portions and back segment angulation β are separately obtuse angle, are preferably 120～150 degree.
Still referring to Fig. 3, in described air-conditioning air inlet duct intermediate plate structure 20, after allowing pedestrian head clash into, there is rapidly conquassation herein, the angle Φ in the stage casing 200 of the back segment of intermediate plate structure 20 and upper plate structure 10 equals the stage casing 300 of intermediate plate structure 20 and the angle Φ of the leading portion 400 of lower plate structure 30, angle Φ of the present invention is 40～60 degree, is preferably in the present embodiment 45 degree.This kind of structure of the present invention makes in the time that pedestrian head 4 strikes the upper plate structure 10 of air-inlet grille, and conquassation more easily occurs in the stage casing 300 of intermediate plate structure 20, thereby further reduces the injury to pedestrian head.
Referring to Fig. 4, when pedestrian head 4 has just struck Windshield 2 bottom, air-conditioning air inlet duct structure 1 of the present invention contacts with the bottom of Windshield 2 by sealing member 5, and matches with self-propelled vehicle front deck fireproof brickwork 3.
Referring to Fig. 5, along with pedestrian head 4 clashes into the increase of the degree of depth, break in the bottom of Windshield 2, and on air-conditioning air inlet duct, plate structure 10 deforms, and further compresses intermediate plate structure 20, makes air-conditioning air inlet duct structure 1 that conquassation occur.Owing to adopting " Z " tee section in air-conditioning air inlet duct structure 1 of the present invention, therefore after air-conditioning air inlet duct structure 1 is compressed, the structure of this form is compared with traditional shaped cross, more easily there is conquassation and bending, fully absorb pedestrian head Impact energy, thereby greatly reduce the impact acceleration of pedestrian head, and then reduce the injury of pedestrian head.
Obviously, those of ordinary skill in the art, can be by a kind of motor vehicle air conditioning air inlet duct structure that is applicable to pedestrian protecting head impact of the present invention, forms various types of air inlet duct mechanism.
Above-described embodiment is used for illustrative purposes only; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the present invention; can also make various variations and modification; therefore all technical schemes that are equal to also should belong to category of the present invention, and scope of patent protection of the present invention should be limited by each claim.
