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, particularly the crash bar on sedan door.
Background technology
Present automobile industry development is rapid, and in order to improve the collision safety of sedan door, general increasing on the driver door of car has crash bar.Due to the insufficient space in door panel, after the crash bar bending, its two ends still exist with the car door contents interferes.Therefore, the two ends of crash bar should be done to flatten and process, so that crash bar is installed.Crash bar is generally steel-tube construction, if directly flatten the end of crash bar, steel pipe can by pressure break, can't satisfy operating needs; If the employing drop stamping will cause cost to increase substantially.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of sedan door crash bar that can effectively avoid pressure break.
Technical scheme of the present invention is as follows: a kind of sedan door crash bar, have the body of rod (1), and 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, solved and to have been improved the power resistance strength at body of rod two ends by the problem of pressure break after rod end directly flattens, guaranteed that crash bar can satisfy operating needs.
As preferably, described journal stirrup (2) adopts cold stamping shaped, passes through conical section (3) transition between journal stirrup (2) and the body of rod (1).Adopt above structure, the cold punching technology moulding is simple and direct, can reduce production costs; Be connected by the garden section of cone transition between journal stirrup and the body of rod, can be issued to the effect of destressing in the situation that is subject to the outside application of force, further improved the power resistance strength of crash bar.
For with sedan door in the installation site adapt, so that crash bar assembles fast, and guarantee the fixing that assembles, journal stirrup (2) suitable length that is positioned at the body of rod (1) front end is 50～60mm, and journal stirrup (2) suitable length that is positioned at the body of rod (1) rear end is 110～120mm.
As preferably, journal stirrup (2) length that is positioned at the body of rod (1) front end is preferably 58mm, and journal stirrup (2) length that is positioned at the body of rod (1) rear end is preferably 113mm.
In order to weaken the deformation extent of sedan door when colliding, improve the intensity that is impacted of crash bar, take into account simultaneously the effect that the body of rod is easy to moulding, the described body of rod (1) is preferably pipe, and the 40Cr tubing that is preferably 2.5mm by thickness is made.
Beneficial effect: the present invention changes by the journal stirrup with crash bar two ends the structure that cross-sectional plane is the figure of eight into, after having solved the direct flattening of rod end, meeting is by the problem of pressure break, improved the power resistance strength at body of rod two ends, have design ingenious, simple in structure, be easy to processing and fabricating, transformation easily, the characteristics such as improvement cost is low, all applicable on various types of cars.
Description of drawings
Fig. 1 is front view of the present invention.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is that the A-A of Fig. 1 is to view.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
As Fig. 1, Fig. 2 and shown in Figure 3, the crash bar of sedan door has the body of rod 1, and the described body of rod 1 is pipe, is made by the 40Cr tubing that thickness is 2.5mm.Certainly, as the replacement that is equal to, the material of the body of rod 1 and thickness can be adjusted 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 and 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 that are positioned at the body of rod 1 front end are 50～60mm, and the present embodiment is preferably 58mm, and journal stirrup 2 length that are positioned at the body of rod 1 rear end are 110～120mm, and the present embodiment is preferably 113mm.
