Detailed description of the invention
Embodiment with reference to accompanying drawing and following explanation just can specify advantage of the present invention and feature and reach its method.But, the present invention is not defined in the embodiment of following discloses, but realize with mutually different variform, the present embodiment only makes of the present invention open more complete, make the category that general technical staff of the technical field of the invention's easy understand is invented, the present invention is defined by the category of technical scheme.Further, in specification sheets full text, identical Reference numeral represents identical inscape.
Hereinafter, with reference to the accompanying drawings of the pedestrian air bag's module according to the embodiment of the present invention.
Fig. 1 is the block diagram that display is suitable for the vehicle local of one embodiment of the invention, and Fig. 2 is the block diagram of pedestrian air bag's module of display one embodiment of the invention, and Fig. 3 is the section-drawing of pedestrian air bag's module of display one embodiment of the invention.
Referring to figs. 1 through Fig. 3, the vehicle 1 being suitable for pedestrian air bag's module of one embodiment of the invention comprise the engine 50 producing vehicle power, the upside being configured at engine 50 protecting the car bonnet 10 of engine 50, be configured at the Windshield 20 at the rear of car bonnet 10, be configured at collection canopy 60 between Windshield 20 and car bonnet 10, be configured at the cover plate 30 that collects between canopy 60 and engine 50 and be arranged at the pedestrian air bag's module 100 collecting canopy 60.
Described car bonnet 10 is combined into by the inner panel of outside plate with the downside being configured at outside plate.The outside plate of car bonnet 10 affects more by outside rain, wind etc., therefore preferably makes with the material of excellent corrosion resistance, and inner panel is more by the impact of engine 50 heat, therefore preferably makes with the material of excellent heat resistance.
On the one hand; described car bonnet 10 arranges front side is rotated up and down centered by rear side; because when colliding on front side of pedestrian and vehicle 1, pedestrian can be poured on car bonnet 10, be therefore protection pedestrian, car bonnet 10 is preferably made with absorbing the elastomeric material impacted.
Windshield 20 is configured at the rear of car bonnet 10, prevents rain, wind etc. from entering by bus space, makes for guaranteeing the visual field of chaufeur with transparent material.
Collection canopy 60 is configured between Windshield 20 and car bonnet 10, and pedestrian air bag's module 100 is arranged on described collection canopy 60.
The surface of described collection canopy 60 is formed with salient 40, and the side of described salient 40 is formed with cut (Opening) 41.The local of pedestrian air bag's module 100 is inserted and is arranged at described cut 41 inside, and the upside to collection canopy 60 is protruded.Described collection canopy 60 is provided with for the wiper installation portion in conjunction with wiper on the upside of it, and is formed with the air suctiton inlet entering indoor for external air flow.
Cover plate 30 is configured at the downside of car bonnet 10.During for preventing vehicle 1 frontal collisions, the device such as engine 50 and change-speed box is to side, space invasion by bus, and cover plate 30 is made up of the rigid construction of high rigidity.The preferable shape of cover plate 30 affects less shape by air resistance.
Further, cover plate 30 is configured between collection canopy 60 and engine 50, and the heat produced to reduce engine 50 has an impact to pedestrian air bag's module 100.That is, the heat that cover plate 30 prevents engine 50 from producing causes pyrolytic damage to pedestrian air bag's module 100.The rear of cover plate 30 is incorporated into the downside of collection canopy 60 by welding, lock bolt or support (not shown).
The present invention includes: for occur gas gas generator 120, the fashionable expansion of gas flow air bag cushion 110 and hold the air-bag shell 130 of described gas generator and air bag cushion.
The upper lateral part of described air-bag shell 130 is configured at immediately below the rear lateral portion 11 of car bonnet 10 at least partially, when air bag cushion 110 launches, rear lateral portion 11 from air bag cushion 110 to upside jack-up car bonnet 10 while launch to Windshield 20 side.
Described air-bag shell 130 is made up of the housing 131 holding air bag cushion 110 and gas generator 120 and the cover body portion 132 that covers described housing 131.The upper lateral part in described cover body portion 132 is formed with the line of rupture 133 of the fracture when air bag cushion 110 launches.Therefore, when air bag cushion 110 launches, described line of rupture 133 ruptures, thus the air bag cushion 110 being configured at air-bag shell 130 inside can easily to air-bag shell 130 external expansion.For guiding air bag cushion 110 to launch to Windshield 20 side, line of rupture 133 is preferably formed in the bight of Windshield 20 side in the upper lateral part of air-bag shell 130.
The cover body portion 132 of air-bag shell 130 is by the excellent thermoplastic olefin (TPO of rigidity; ThermoPlastic Olefine) or thermoplastic elastomer (TPE; Thermo Plastic Elastomer) material makes, thus can prevent the cover body portion 132 when air bag cushion 110 launches from rupturing with line of rupture 133 and disperse, broken phenomenon.
On the one hand, a side surface part in described cover body portion 132 is incorporated into collection canopy 60 by lock bolt 71, and the opposite side face in described cover body portion 132, a side surface part of housing 131 and gas generator 120 are incorporated into described collection canopy 60 by locking member 72.The bottom surface 61 that described housing 131 is positioned at described collection canopy 60 supports by it.
The gas flow that air bag cushion 110 occurs at gas generator 120 is fashionable to launch to Windshield 20 side.That is, air bag cushion 110 launches rearwardly and upwardly.Therefore, when protecting with air bag cushion during pedestrian collision 110 pedestrian head hitting Windshield 20 on front side of vehicle 1.The head contact of air bag cushion 110 and pedestrian, therefore preferred soft fiber (fabric) material is made.
Fig. 3 is the section-drawing of state before the air bag cushion of pedestrian air bag's module of display one embodiment of the invention launches, and Fig. 4 is the section-drawing of state after display air bag cushion launches.Fig. 5 is the block diagram of the air bag cushion deployed condition of pedestrian air bag's module of display one embodiment of the invention.
The effect of pedestrian air bag's module of the present invention as constructed as above is described with reference to Fig. 3 to Fig. 5.
As vehicle 1 and pedestrian collision, the health of pedestrian is poured on car bonnet 10, and head and the Windshield 20 of pedestrian collide.Now, first impact between pedestrian is absorbed, to protect pedestrian by having elastomeric car bonnet 10.
Then, time on front side of vehicle 1 with pedestrian collision, the air bag control unit (ACU of vehicle 1 inside is arranged at; Airbag Control Unit) start the gas generator 120 of pedestrian air bag's module 100, produce the gas of high temperature, high pressure.The gas of high temperature, high pressure flows into the inside of air bag cushion 110, and air bag cushion 110 launches to Windshield 20 side.
The gas that gas generator 120 occurs flows into rapidly the inside of air bag cushion 110, and therefore to launch pressure large for air bag cushion 110.The large expansion pressure of air bag cushion 110 makes the line of rupture 133 of air-bag shell 130 rupture, air bag cushion 110 to air-bag shell 130 external expansion, by rear lateral portion 11 from the expansion pressure of air bag cushion 110 to upside jack-up car bonnet 10 while launch to Windshield 20 side.
The air bag cushion 110 being filled gas launches at the front U-shaped of Windshield 20.Therefore, the head of pedestrian hits on the air bag cushion 110 being filled gas and is protected.
Be explained above the preferred embodiments of the present invention, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of technical solution of the present invention.
