Problems solved by technology

[0006] The present invention mainly solves the technical problem that the car door in the prior art is easily deformed during the side impact process, thereby squeezing the interior space of the car, and provides a vehicle with strong anti-side impact ability, which avoids the impact caused by the interior space. A new type of door that is deformed by restraining side impacts caused by process extrusion that poses a threat to the life safety of the occupants

Embodiment

[0018] Example: such as figure 1 , figure 2 As shown, the present invention is a new type of car door that restrains side impact deformation, including a door body and an interior trim panel. The door body is composed of an outer panel 11, an anti-collision beam, a reinforcement panel, and an inner panel 13. An outer frame is provided on the edge of the outer panel. 12. The inner panel is fixed on the outer frame 12, and the inner panel is provided with a high-strength anti-stretch fiberboard 3 attached thereto, and the upper, lower, left, and right edges of the inner panel are provided with mutual The corresponding bolt hole is provided with an elastic bushing 41 with an "I"-shaped axial section. The elastic bushing 41 is matched with the nut 43 . The bolt spacing on the upper and lower sides is 12cm, and the bolt spacing on the left and right sides is 1.5 times the bolt spacing on the upper and lower sides. The elastic bushing has a protective effect on the bolt holes, s...

Abstract

The invention relates to a novel vehicle door for constraining the deformation caused by side impact. The novel vehicle door comprises a vehicle door body and an interior trim panel, wherein the vehicle door body consists of an outer plate, an anti-collision beam, a reinforcing plate and an inner plate, wherein an outer framework is arranged on the edge of the outer plate; the inner plate is fixed on the outer framework; a high-strength tensile fiberboard attached to the inner plate is arranged on the inner plate; the high-strength tensile fiberboard and the inner plate are fixed on the outer framework; and the interior trim panel is fixed on the outer side of the high-strength tensile fiberboard. The novel vehicle door disclosed by the invention has the characteristics of stronger side impact resistance and capability of avoiding the threatening to the life safety of passengers due to extrusion of space in the vehicle.

Description

[0001] technical field [0002] The invention relates to a car door, in particular to a deformation-resistant car door. [0003] Background technique [0004] When a car has a side collision accident, the buffer distance from the door outer panel to the occupant is short, and the damage to the occupant is mainly caused by the collapse of the door sheet metal to the occupant compartment, squeezing the interior panel, the interior panel contacts the occupant and the interior The board pushes the occupant away. Existing side impact safety technologies (such as installing side airbags) all hope to protect the occupants by alleviating the impact of the collision, but there is a problem that cannot be ignored: when the door sheet metal parts are excessively deformed, the space of the occupant compartment is encroached, The occupant is squeezed, and the life safety of the occupant will also be threatened. Therefore, in addition to mitigating the impact of side collisions, consid...
