Abstract

An automotive door enhanced with absorption performance for collision energy in a side collision. The automotive door is constructed of an outer panel and an inner panel, and includes a door beam for a side collision therewithin, and a glass ascending/descending space between the inner panel and the door beam for a side collision including a reinforcing panel disposed in a space between the outer panel and the glass ascending/descending space and joined with both of the outer panel and the door beam for a side collision.

Claims

1. An automotive door constructed of an outer panel and an inner panel, comprising a door beam for a side collision therewithin, and provided with a glass ascending/descending space between the inner panel and the door beam for a side collision, wherein a reinforcing panel disposed in a space between the outer panel and the glass ascending/descending space and joined with both of the outer panel and the door beam for a side collision is provided.

2. The automotive door according to claim 1 wherein the reinforcing panel has a shape matching the inside shape of the outer panel at least in the vehicle anteroposterior direction.

3. The automotive door according to claim 1 wherein the reinforcing panel has a shape matching the inside shape of the outer panel in the vehicle anteroposterior direction and vertical direction.

4. The automotive door according to claim 1 wherein the reinforcing panel is joined with the door beam for a side collision in its face of the vehicle inner side.

5. The automotive door according to claim 1 wherein the reinforcing panel is joined with the door beam for a side collision in its face of the vehicle outer side.

6. The automotive door according to claim 1 wherein the reinforcing panel is joined with the inner panel or the outer panel in at least one position in the vicinity of the end part in the upper side, lower side, front side, and rear side.

7. The automotive door according to claim 3 wherein the reinforcing panel is joined with the outer panel in the end part in the upper side, lower side, front side, and rear side, and the inner panel is joined with the reinforcing panel without extending up to the upper and lower end parts and the front and rear end parts of a space formed inside a door.

8. The automotive door according to claim 1 wherein the reinforcing panel comprises a base part and a protruded part protruding from the base part toward the vehicle inner side.

9. The automotive door according to claim 1 wherein the reinforcing panel comprises unevenness.

10. The automotive door according to claim 9 wherein a difference in the height of the unevenness is larger in a position apart from the door beam than in the vicinity of the door beam.

11. The automotive door according to claim 9 wherein the shape of the unevenness is of a bead shape parallel in the vehicle vertical direction or vehicle anteroposterior direction.

12. The automotive door according to claim 1 wherein the door beam for a side collision comprises a plurality of door beams and the reinforcing panel is joined with all of the door beams.

13. The automotive door according to claim 12 wherein all of the door beams for a side collision are arranged so that the longitudinal direction of each becomes the vehicle anteroposterior direction.

14. The automotive door according to claim 12 wherein the reinforcing panel is joined with one of the door beams at a plurality of locations whose position in the vehicle width direction differs with each other.

15. The automotive door according to claim 12 wherein the door beam is arranged so that its both end parts are directed to a door hinge, a door lock, or a stopper restricting intrusion of a door into a cabin in a side collision.

16. The automotive door according to claim 12 wherein the reinforcing panel comprises unevenness.

17. The automotive door according to claim 16 wherein the unevenness is a plurality of beads arranged to be parallel with each other, and the reinforcing panel and the door beams are joined with each other so that the angles formed by the beads and each of the door beams in their both sides become same.

18. The automotive door according to claim 1 wherein the reinforcing panel is constructed by any of a steel sheet, a sheet material of aluminum or aluminum alloy, or a fiber-reinforced resin molded article.

19. The automotive door according to claim 1 wherein the door beam is constructed by any of a press-formed article of a steel sheet, a steel pipe, or an extruded shape of aluminum or aluminum alloy.

20. The automotive door according to claim 2 wherein the reinforcing panel is joined with the inner panel or the outer panel in at least one position in the vicinity of the end part in the upper side, lower side, front side, and rear side.
