Abstract

The utility model provides a front cross beam structure of an automobile, belonging to the field of automobiles and solving the technical problems that the existing front cross beam structure is easy to cause serious wounds to knees and shank parts of a pedestrian. The front cross beam structure of the automobile comprises a front cross beam arranged at the front part of a head end, and is characterized in that a front upper side of the front cross beam is fixedly provided with a protective beam parallel to the front cross beam. When in practical use, a front bumper is arranged outside the protective beam, when a front collision occurs, the front bumper can slow down the impact to femorals, and can prevent the front bumper from being excessively deformed towards the side of an engine under the action of the protective beam, thus blocking the knees and shanks of human body outside the front cross beam, avoiding the contact of the knees or shanks with the front cross beam, and effectively protecting the areas which are easy to be hurt, such as the knees and shanks.

Description

A kind of front cross rail structure of automobile
Technical field
The utility model relates to a kind of front cross rail structure of automobile, belongs to automotive field.
Background technology
Reduce damage to car body in order to reduce automobile when crashing, existing automobile generally all distinguish the erection insurance thick stick on car body before and after it, by the distortion of bumper/spoiler the huge impact amount of overcoming is alleviated, and is reduced the personnel's of riding injures and deaths.Front bumper is installed in the front portion of machinery space, the thigh position of its general corresponding human body of height, the bottom of front bumper is provided with in parallel and is used to connect the front cross rail of left and right sides vehicle body, the knee and the shank of the corresponding human body of the height of front cross rail, when vehicle when positive collision accident takes place, front bumper impinges upon on the thigh of human body, front cross rail clashes into the knee and the shank of human body simultaneously, but because front bumper is softer, can alleviate injury to thigh, and the front cross rail rigidity is big, makes knee and shank be subjected to serious bump, and existing automobile does not also make improvements the pedestrains safety aspect.
Summary of the invention
The utility model provides a kind of front cross rail structure of automobile, and front cross rail contacted with human body when this structure can prevent to clash in the front, thereby effectively reduces the injury that the pedestrian is caused.
The purpose of this utility model can realize by following technical proposal: the front cross rail structure of automobile, comprise the front cross rail that is located at the headstock front portion, and it is characterized in that the front upper place of described front cross rail is installed with guard beam in parallel.
The front cross rail structure of this automobile, form by front cross rail and the guard beam that is fixed on its front upper place, when reality is used, front bumper is installed in outside the guard beam, it is the outermost that front bumper is positioned at headstock, when the head-on crash accident takes place when, automobile is the relative strong femoral region of front bumper and human body with pedestrian's first make contact, because front bumper is softer, the rigidity of guard beam is big, thereby makes impulsive force obtain buffering, make the injured lighter of thigh position, again because guard beam is positioned at the front side of front cross rail, make front cross rail not can with knee, the contact of shank position alleviates the injury to human body thus.
In the front cross rail structure of above-mentioned automobile, be provided with the detouchable connection structure between described guard beam and the front cross rail.If automobile causes guard beam to damage when accident, only need to change guard beam and get final product, and need not to change whole front cross rail structure, but cost-cutting.
In the front cross rail structure of above-mentioned automobile, described connection structure is to be installed with some adapter plates alternately on guard beam, and each adapter plate fixes by screw and front cross rail.When changing guard beam, as long as lay down screw, dismounting, easy to maintenance.
In the front cross rail structure of above-mentioned automobile, described adapter plate is located at the rear side of guard beam.Adapter plate is located at the rear side of guard beam, and guard beam is positioned at the front side of front cross rail, makes on the one hand to help installed in front front bumper on the other hand by compact conformation at guard beam.
In the front cross rail structure of above-mentioned automobile, described guard beam and adapter plate are by being welded to connect or fastener is connected.
In the front cross rail structure of above-mentioned automobile, the cross sectional shape of described guard beam is a U-shaped.The U-shaped guard beam can pass through the steel plate punch forming, and is simple in structure, the intensity height.
Compared with prior art; the front cross rail structure of this automobile mainly is provided with guard beam in the front upper place of front cross rail; front bumper is located at outside the guard beam; when head-on crash took place, front bumper can be extenuated the impact to thigh, under the effect of guard beam; can prevent that bumper/spoiler is excessive to the distortion of driving engine one side; thereby the knee of human body and shank position are kept off outside front cross rail, avoid knee or shank position to contact, thereby effectively protected vulnerable zones such as knee and shank with front cross rail.
Description of drawings
Fig. 1 is the upright TV structure scheme drawing of the front cross rail structure of the utility model automobile;
Fig. 2 is the decomposition texture scheme drawing of the front cross rail structure of the utility model automobile;
Fig. 3 is the side-looking structural representation of the front cross rail structure of the utility model automobile.
Among the figure, 1 front cross rail; 2 guard beams; 3 adapter plates; 4 screws.
The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, the front cross rail structure of this automobile, be located at the headstock front portion, this structure mainly is made up of front cross rail 1 and guard beam 2, and guard beam 2 is parallel with front cross rail 1, as shown in Figure 3, guard beam 2 is positioned at the front upper place of front cross rail 1, in order to reduce the damage to this vehicle, when reality is used, also need front bumper is installed guard beam 2 outside, the direct and external object of front bumper is collided.
When guard beam 2 damages, in order to save cost, guard beam 2 is connected removably with front cross rail 1, like this, only need to change guard beam, and need not to change the front cross rail of its below, as shown in Figure 2, welded 3 horizontal adapter plates 3 alternately on guard beam 2, each adapter plate 3 fixes by screw 4 and front cross rail 1.In order not influence the installation of front bumper, need adapter plate 3 is located at the rear side of guard beam 2, so also make good looking appearance, compact conformation.In addition, also can be connected between guard beam 2 and the adapter plate 3 by fastener, clamping connection etc.
Certainly, guard beam 2 and front cross rail 1 also are feasible by the pressure fixed form such as being welded to connect.
In actual manufacturing process, guard beam 2 can directly strike out the U-shaped beam by steel plate, and promptly the cross sectional shape of guard beam 2 is a U-shaped, the guard beam intensity height of this structure.
