Abstract
The invention discloses a bumper bar of a car door of a passenger car. The bumper bar of the car door of the passenger car comprises a rod body (1), flat supporting lugs (2) are arranged at the front end and the rear end of the rod body (1), and the sectional face of each supporting lug is of the shape of the number '8'. Due to the fact that the sectional face of the supporting lugs at the two ends of the bumper rod are changed into the shape of the number '8', the problem that the end portion of the rod body breaks after being pressed is solved, resistance intensity of the two ends of the rod body is improved, and the bumper bar of the car door of the passenger car has the advantages of being exquisite in design, simple in structure, prone to being processed and manufactured, easy to modify, low in modifying cost and the like, and is suitable for all kinds of passenger cars.
Description
Technical field
The present invention relates to a kind of automobile component, the crash bar particularly on sedan door.
Background technology
Current automobile industry development is rapid, in order to improve the collision safety of sedan door, generally increasing on the driver door of car and having crash bar.Due to the insufficient space in door panel, after crash bar is bending, its two ends still exist with car door contents interferes.Therefore, the two ends of crash bar should be done to flatten process, so that crash bar is installed.Crash bar is generally steel-tube construction, if the end of crash bar is directly flattened, steel pipe by pressure break, can cannot meet operating needs; According to drop stamping, cost will be caused to increase substantially.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of Bumper bar of car door of passenger car effectively avoiding pressure break.
Technical scheme of the present invention is as follows: a kind of Bumper bar of car door of passenger car, there is the body of rod (1), be equipped with flat journal stirrup (2) in the rear and front end of the body of rod (1), the cross-sectional plane of described journal stirrup (2) is the figure of eight.
The present invention changes the journal stirrup at body of rod two ends into structure that cross-sectional plane is the figure of eight, and moulding is simple on the one hand, is easy to processing and fabricating; On the other hand, solve after rod end directly flattens and by the problem of pressure break, the power resistance strength at body of rod two ends can be improve, ensure that crash bar can meet operating needs.
As preferably, described journal stirrup (2) adopts cold stamping shaped, by conical section (3) transition between journal stirrup (2) and the body of rod (1).Adopt above structure, cold punching technology is shaping simple and direct, can reduce productive costs; Be connected by garden cone section transition between journal stirrup with the body of rod, the effect of destressing can be issued in the situation being subject to outside force, further increase the power resistance strength of crash bar.
In order to adapt with the installation site in sedan door, so that crash bar quick assembling, and guarantee the fixing of assembling, journal stirrup (2) suitable length being positioned at the body of rod (1) front end is 50 ~ 60mm, and journal stirrup (2) suitable length being positioned at the body of rod (1) rear end is 110 ~ 120mm.
As preferably, journal stirrup (2) length being positioned at the body of rod (1) front end is preferably 58mm, and journal stirrup (2) length being positioned at the body of rod (1) rear end is preferably 113mm.
In order to weaken the deformation extent of sedan door when colliding, improving the intensity that is impacted of crash bar, taking into account the effect that the body of rod is easy to shaping simultaneously, the described body of rod (1) is preferably pipe, and the 40Cr tubing being preferably 2.5mm by thickness is made.
Beneficial effect: the present invention is by changing the journal stirrup at crash bar two ends into structure that cross-sectional plane is the figure of eight, solve after rod end directly flattens and understand by the problem of pressure break, improve the power resistance strength at body of rod two ends, there is the features such as design is ingenious, structure simple, be easy to processing and fabricating, transformation is easy, improvement cost is low, all applicable on various types of car.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the A-A direction view of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, Figure 2 and Figure 3, the crash bar of sedan door has the body of rod 1, and the described body of rod 1 is pipe, and the 40Cr tubing being 2.5mm by thickness is made.Certainly, as equivalent replacement, the material of the body of rod 1 and thickness can adjust according to actual needs.Be equipped with cold stamping shaped flat journal stirrup 2 in the rear and front end of the described body of rod 1, the cross-sectional plane of each journal stirrup 2 is the figure of eight, and is connected by conical section 3 transition between journal stirrup 2 with the body of rod 1, and journal stirrup 2, the body of rod 1 and conical section 3 are structure as a whole.Journal stirrup 2 length being positioned at the body of rod 1 front end is 50 ~ 60mm, and the present embodiment is preferably 58mm, and journal stirrup 2 length being positioned at the body of rod 1 rear end is 110 ~ 120mm, and the present embodiment is preferably 113mm.
