Description
Technical field
The utility model belongs to technical field of automobile parts, particularly a kind of arrangements for automotive doors.
Background technology
Arrangements for automotive doors and vehicle body are fixed, and arrangements for automotive doors generally comprises a body, door accessories and interior decorative cover plate.The inner plate of car door that the door body comprises door skin, is connected with door skin is installed with the car door strength beam for reinforced door body bulk strength between the car door Office of Foreign Affairs and inner plate of car door.Door accessories generally comprises is located at the interior Door Lock of a body etc.Interior decorative cover plate comprises the adapter plate fixing with the inboard of inner panel, generally is installed with handrail on adapter plate, then wraps up by cortex.
In side impact, protect occupant's shoulder for automobile; in in the past, tend to be fixed with the safety air bag bag in the seat board side of automotive seat; when automobile generation side collision and impact force surpass setting value; direction towards car roof after the safety air bag Bao Huijing inflation expands, thereby protection occupant's shoulder regions is injury-free.Being positioned at when this locational safety air bag wraps in automobile and bumps to protect occupant's shoulder regions injury-free; but the automotive seat of this structure are in use often found to bump impulsive force when larger when automobile, and the safety air bag bag has little time to expand and the occupant is caused larger damage.
For the problems referred to above, Chinese utility model patent [ZL201020533587.X] discloses a kind of " air bag device in the self-propelled vehicle ", also safety air bag dress bag is located in the groove of offering on the Door Armrest body of self-propelled vehicle, described Door Armrest body is wrapped with uppermost layer, and safety air bag is positioned at described uppermost layer.The arrangements for automotive doors of this structure can be in the larger side collision of automobile generation impulsive force, and safety air bag can in time expand, thus protection occupant's safety.But because the safety air bag bag expands towards the shoulder direction from occupant's shoulder below, and the process of safety air bag bag inflation is to finish within the extreme time, tend in actual applications to find that safety air bag wraps in the chest that can meet the occupant in the middle of the process of expansion, the power that the safety air bag bag expands is rapidly impacted occupant's chest, like this can be to occupant's chest injury.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology; a kind of arrangements for automotive doors has been proposed; this car door can discharge safety air bag in automobile generation side impact; safety air bag can protect occupant's shoulder regions injury-free, and avoid safety air bag in the middle of the process that expands to occupant's chest region injury.
The purpose of this utility model can realize by following technical proposal: a kind of arrangements for automotive doors, comprise a body and the interior decorative cover plate that is fixed on a body inboard, be provided with Door Armrest at interior decorative cover plate, it is characterized in that, the interior trim side edge thereof place that is positioned at Door Armrest top offers for the groove of placing the safety air bag bag, be fixed with in the described groove when arrangements for automotive doors clashed into and impact can expand rapidly when surpassing setting value and covering car door guard bar top in the safety air bag bag of decorative cover plate.
When automobile generation side collision and impact surpass setting value; the safety air bag bag directly expands towards occupant's shoulder direction; the position of handrail top and occupant's shoulder is distant simultaneously; can be not directly member's shoulder and chest region do not caused greater impact; so just realized in automobile generation side collision the safety air bag bag to occupant's protection, and avoid safety air bag in the middle of the process that expands to occupant's chest region injury.
In above-mentioned arrangements for automotive doors, described safety air bag bag comprises and is fixed in the groove after inflation the airbag of decorative cover plate in the covering car door guard bar top, and described airbag is connected with a gas filled device of airbag being inflated during above setting value when automobile generation side collision and impact force.
In above-mentioned arrangements for automotive doors, described gas filled device comprises gas generator, pressure sensor and the control unit that is connected with airbag, described control unit is electrically connected mutually with gas generator and pressure sensor respectively, in described pressure sensor setting and the door body.Control unit is mainly used in receiving the data of pressure sensor, carries out simultaneously the analysis of data, then gas generator is sent instruction.When automobile bumps, the pressure that pressure sensor will be subject in the time of will bumping passes to control unit, when the data that receive surpassed the setting value of control unit, control unit sent the inflation instruction to gas generator, and gas generator is inflated airbag.
In above-mentioned arrangements for automotive doors, described groove diapire is provided with connecting bore one, face connecting bore one at the door body and be provided with connecting bore two, bolt pass connecting bore one and connecting bore two with described airbag fixing with groove in.By bolt airbag is fixed in the groove, is convenient to assembling.
In above-mentioned arrangements for automotive doors, described airbag ovalize behind inflation, the length direction of described airbag is consistent with the length direction of automobile B-column, and the scope of the one-tenth-value thickness 1/10 of described airbag is 50m-80mm.Ovalize can increase the area of contact of airbag and occupant's shoulder regions like this after the airbag inflation, improves safety performance.The one-tenth-value thickness 1/10 of airbag is determined by the space size between decorative cover plate in the Door Armrest top and the occupant's shoulder, and desirable larger value when this space is larger is if less value hour, then should be got in this space.The thickness of choosing greatly airbag when above-mentioned space is less, in the time of automobile generation side collision, the occupant can run into airbag again towards above-mentioned airbag displacement one segment distance, main by the protection of safety strap to human body before running into airbag, like this along with the increase of human body towards the displacement of airbag direction, human body is subject to power that safety strap pulls will be larger, and at this moment, safety strap is easily to the chest region injury of human body; And when above-mentioned space less, when the one-tenth-value thickness 1/10 of airbag is larger, automobile generation side collision, the occupant is towards the direction displacement of airbag, the impulsive force that airbag expands can be to occupant's shoulder injury, even the also in time inflation of occupant's airbag, and the occupant bumps with car door.
Compared with prior art; a kind of arrangements for automotive doors of the utility model; its interior trim side edge thereof place above Door Armrest offers for the groove of placing the safety air bag bag; be fixed with in the groove when arrangements for automotive doors clashed into and impact can expand rapidly when surpassing setting value and covering car door guard bar top in the safety air bag bag of decorative cover plate; in the time of automobile generation side collision; the safety air bag bag directly expands towards occupant's shoulder direction; the position of handrail top and occupant's shoulder are distant; can be not directly member's shoulder and chest region do not caused greater impact; so just realized in automobile generation side collision the safety air bag bag to occupant's protection, and avoid safety air bag in the middle of the process that expands to occupant's chest region injury.
