Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the present invention is done further explanation:

[0020] The automobile anti-collision bolt (5) is connected with the automobile door assembly by matching with the welding nut (4) on the inner panel of the door (6), while the outer panel of the side wall (2) and the reinforcing plate of the side wall (1) There are holes of appropriate size. When the car collides, the anti-collision bolts will be offset against the edge of the hole on the side wall. According to the principle of structural mechanics, this structure can make up for the anti-collision plate or anti-collision bar during the collision. Insufficient, effectively strengthen the anti-collision ability of the door, and guide the collision energy into the bottom of the door and the side wall, minimize the deformation of the door, maintain the integrity of the car body, so as to ensure that the occupants in the car are not injured to the greatest extent.

Abstract

The invention relates to an anti-collision structure of the car door. The invention has an additional anti-collision bolt structure based on the traditional car door structure. Bolt gears with a welding nut on the internal plate of the car door to connect with the car door. A matching hole is arranged on the corresponding position of side wall. When collision happens, the anti-collision bolt will balance out the bore brink on the side wall. According to structural mechanics principle, the structure can compensate for the deficiency of an anti-collision plate or an anti-collision rod during the collision, thus effectively improving the anti-collision ability of the car door. In addition, impact energy can be led to the bottom of the car door and to the side wall to possibly reduce the deformation of the door, thus keeping the integrity of the car body and giving maximum possible protection to an occupant to prevent an occupant from getting hurt.

Description

technical field [0001] The invention relates to an automobile body structure, in particular to an automobile door anti-collision structure. Background technique [0002] With the continuous development of my country's automobile industry, the collision safety of automobiles has been paid more and more attention by consumers. As we all know, in the process of frontal collision, offset collision and side collision, if the deformation of the door structure is too large and it is difficult to open, it will seriously threaten the lives of drivers and passengers. [0003] Especially for small-displacement cars, the body structure design must meet the same collision regulations as large-displacement cars in a limited space. For the body structure design, it must be considered that when the door is hit, some structural designs can be used to lighten the door. The degree of deformation can reduce the damage to the occupants in the car when the car hits. This technology is still in ...
