For achieving the above object, this utility model provides following technical scheme: a kind of vehicle door anti-collision joist, including collision prevention girders, front mounting bracket and rear mounting bracket, described collision prevention girders is the steel pipe that high strength steel is made, the side face centre position of described collision prevention girders is fixing connects a fixed mount, in described front mounting bracket, depression forms the limit opening groove that the one end for described collision prevention girders is inserted, in described rear mounting bracket, depression forms the groove suitable with described collision prevention girders side face, one end of described collision prevention girders is plugged in the limit opening groove of described front mounting bracket, the other end inserts in the groove of described rear mounting bracket.
By adopting technique scheme, the collision prevention girders that high strength steel is made is be diagonally mounted inside inside car door by fixed mount, front mounting bracket and rear mounting bracket make anti-collision beam effectively position, after car door is collided, collision prevention girders will not offset, make collision prevention girders impact resistance higher, thus realizing saving the technique effect of material and strong shock resistance.
This utility model is further arranged to: described front mounting bracket and described rear mounting bracket are arranged on described collision prevention girders the same side.
By adopting technique scheme so that the rear front mounting bracket being collided at car door and described rear mounting bracket can simultaneously work as the effect of dispersing impact forces, improve the impact resistance of collision prevention girders further.
This utility model is further arranged to: described front mounting bracket and described rear mounting bracket bending form a bearing surface, are provided with the dashpot of circular arc on described bearing surface.
By adopting technique scheme so that front mounting bracket and described rear mounting bracket have bigger cushion space, improve the impact resistance of collision prevention girders further.
This utility model is further arranged to: also include clamping seat, the section of described clamping seat is " U "-shaped, the open at one end of this " u "-shaped is perpendicular to described clamping seat sidewall and extends outward installing plate, the clamping seat of this " u "-shaped is fastened on the side face of described collision prevention girders, and the opening of described clamping seat is relative with the direction of described limit opening groove and described groove.
By adopt technique scheme, clamping seat is arranged in car door by installing plate so that collision prevention girders location relatively reliable, while clamping seat may also function as certain impact resistance.
This utility model is further arranged to: be provided with undulatory rubbing surface on the Guan Bi end outer wall of the relative " u "-shaped opening of described clamping seat.
By adopting technique scheme, undulatory rubbing surface improves the stability of clamping seat further and simultaneously works as the fixing relatively reliable of collision prevention girders.
This utility model is further arranged to: described clamping seat quantity, for being arranged in pairs, is symmetricly set on the side face of described collision prevention girders centered by fixing seat.
By adopting technique scheme, can strengthening the fixing of collision prevention girders further, after making car door be clashed into, clamping seat may also function as the effect of disperses impact forces simultaneously, thus further improving the impact resistance of collision prevention girders.
Below in conjunction with the drawings and specific embodiments, this utility model is further described.
Accompanying drawing explanation
Fig. 1 is the rear perspective view of this utility model detailed description of the invention;
Fig. 2 is the front perspective view of this utility model detailed description of the invention.
