Abstract

The beam (1) has a generally U shape including a central flange and two webs. The central flange is in a longitudinal middle portion of beam points outwards from a vehicle. A longitudinal/shallow concavity (17) deepens progressively towards end portions of the beam to change to or connect to fastening plates (20, 21). A bottom of the concavity is at an angle of 30 degrees to a transverse direction of the vehicle in a region close to the fastening plates. The concavity broadens at the same time when the concavity deepens, where the concavity becomes deeper than a height of webs.

Description

530 553 2 Figur 5 är en sektion tagen utmed linjen 5-5 i figur 1. 530 553 2 Figure 5 is a section taken along line 5-5 of Figure 1.

Figur 6 är en sektion tagen utmed linjen 6-6 i figur 1.Figure 6 is a section taken along line 6-6 of Figure 1.

Detaljbeskrivning av visat utföringsexempel Den visade stötfångarbalken är formad från ett plant plåtämne. Den har generellt U- formad tvärsektion i sitt mittparti som framgår av figur 4. Den har en centralfläns 12 och två liv 13,14. Liven avslutas med sidoflänsar 15,16, dvs profilen är en hattprofil.Detailed description of the shown exemplary embodiment The shown bumper beam is formed from a flat sheet metal blank. It generally has a U-shaped cross section in its central part as shown in Figure 4. It has a central flange 12 and two webs 13,14. Life ends with side ns 15,16, ie the profile is a hat profile.

Centralflänsen har en grund fördjupning 17 och det undre livet 14 har ett steg 18. Övre livet har en liten vinkelförändring 19 som nästan inte är märkbar, men som fungerar som deformationsinitierare för att ge kontrollerad deformation i händelse av krockbelastning. Övre livets steg 18 fungerar också som deformationsinitierare.The central flange has a shallow recess 17 and the lower web 14 has a step 18. The upper web has a small angular change 19 which is almost not noticeable, but which acts as a deformation initiator to give controlled deformation in the event of a collision load. Upper life stage 18 also acts as a deformation initiator.

Den grunda fördjupningen 17 fördjupas ut mot balkens ändar och vid sektionen 5-5 (figur 5) den lika djup som livens höjd. l detta område har fördjupningens botten en vinkel alfa mot fordonets tvärriktning som är större än 30 grader (den är visad som ungefär 45 grader); dvs fördjupningens botten lutar brant i förhållande till tvärriktningen sett i ett horisontalplan som i figur 3.The shallow recess 17 is recessed towards the ends of the beam and at section 5-5 (figure 5) it is as deep as the height of the web. In this area the bottom of the recess has an angle alpha to the transverse direction of the vehicle which is greater than 30 degrees (it is shown as approximately 45 degrees); ie the bottom of the depression slopes steeply in relation to the transverse direction seen in a horizontal plane as in figure 3.

Fördjupningen 17 planar ut i fästplattor 20,21 anpassade till motsvarande fästytori bärande delar av fordonet. Fästplattorna har ett antal hål 22 för bultar. Fördjupningen 17 breddas samtidigt som den fördjupas så att fästplattorna får lämplig bredd.The recess 17 flattens out in mounting plates 20,21 adapted to the corresponding mounting surface carrying parts of the vehicle. The mounting plates have a number of holes 22 for bolts. The recess 17 is widened at the same time as it is recessed so that the fastening plates have a suitable width.

Stötfångarbalken avslutas i det visade utförandet med fästplattorna, men kan alternativt fortsätta förbi fästplattorna beroende på fordonets design.The bumper beam ends in the shown design with the mounting plates, but can alternatively continue past the mounting plates depending on the design of the vehicle.

Livens 13,14 höjd minskar allteftersom fördjupningen 17 tilltar så att ämnesbredden inte behöver ökas nämnvärt för stötfångarbalkens ändar jämfört med stötfångarbalken mitt. Det kan emellertid i vissa fall vara fördelaktigt att förlänga liven vid fästplattorna så att liven snabbare får kontakt med fordonet vid en krock eller tom initialt har kontakt med fordonet och direkt kan ta upp kraft. 530 553 3 l det visade exemplet är profilen i den centrala delen av balken inte symmetrisk.The height of the web 13,14 decreases as the recess 17 increases so that the blank width does not have to be increased significantly for the ends of the bumper beam compared to the center of the bumper beam. However, in some cases it may be advantageous to extend the life of the mounting plates so that the life comes into contact with the vehicle more quickly in the event of a collision or even initially has contact with the vehicle and can directly absorb force. 530 553 3 In the example shown, the profile in the central part of the beam is not symmetrical.

Detta är enbart en anpassning till designen av fordonet till vilken stötfångarbalken är anpassad. Även andra anpassningar kan göras inom patentkravens ram.This is only an adaptation to the design of the vehicle to which the bumper beam is adapted. Other adjustments can also be made within the scope of the claims.
