Abstract

A vehicle door structure includes an inner panel, an outer panel, a guard beam and a reinforcing member. The guard beam extends laterally in a cavity between the inner and outer panels. The reinforcing member disposed in the cavity and being positioned on a floor of the vehicle door structure below the guard beam.

First claim

What is claimed is:

1. A vehicle door structure comprising:
an inner panel;
an outer panel;
a guard beam extending laterally in a cavity between the inner and outer panels, the guard beam extending across a speaker unit mounting hole of the inner panel; and
a reinforcing member disposed in the cavity and being positioned on a floor of the vehicle door structure below the guard beam, the floor of the vehicle door structure having a bottommost surface of the cavity, the reinforcing member being disposed substantially directly below the speaker unit mounting hole.

2. The vehicle door structure according to claim 1 , wherein
the reinforcing member includes an inboard facing surface that aligns with and contacts a stamped surface of the inner panel.

3. A vehicle door structure comprising:
an inner panel;
an outer panel;
a guard beam extending laterally in a cavity between the inner and outer panels; and
a reinforcing member disposed in the cavity and being positioned on a floor of the vehicle door structure below the guard beam, the floor of the vehicle door structure having a bottommost surface of the cavity,
the reinforcing member includes an inboard facing surface that aligns with and contacts a stamped surface of the inner panel,
the reinforcing member including a positioning structure having an extension extending from a forward facing side of the reinforcing member, the extension contacting a front hem of the inner panel.

4. The vehicle door structure according to claim 3 , wherein
the reinforcing member includes a plurality of contact steps disposed on the inboard facing side of the reinforcing member.

5. The vehicle door structure according to claim 4 , wherein
the stamped surface of the inner panel includes a plurality of corresponding contact steps that contacts and receives the contact steps of the reinforcing member.

6. The vehicle door structure according to claim 5 , wherein
the inner panel includes a front part having a front hem and a rear part having a rear hem of the vehicle door structure, the reinforcing member being supported by both the front and rear parts.

7. The vehicle door structure according to claim 6 , wherein
the front part includes at least one of the plurality of corresponding contact steps for receiving one of the plurality of contact steps of the reinforcing member, and
the rear part includes at least one of the plurality of corresponding contact steps for receiving another one of the plurality of contact steps of the reinforcing member.

8. The vehicle door structure according to claim 1 , wherein
the inner panel includes a front part having a front hem and a rear part having a rear hem of the vehicle door structure, the reinforcing member being disposed on both the front and rear parts.

9. The vehicle door structure according to claim 8 , wherein
the guard beam is fixedly connected to the front part and the rear part.

10. The vehicle door structure according to claim 9 , wherein
the front and rear parts are aligned to form the speaker mounting hole.

11. The vehicle door structure according to claim 10 , further comprising
a speaker mounted in the speaker mounting hole and secured to the inner panel.

12. The vehicle door structure according to claim 11 , wherein
the reinforcing member includes a blind bore for receiving a fastener that mounts the speaker to the inner panel.

13. The vehicle door structure according to claim 1 , wherein
the reinforcing member includes an inboard facing surface that contacts a stamped surface of the inner panel, an outboard facing surface that contacts the outer panel, and a front hem facing surface that contacts a front hem.

14. A vehicle door structure comprising:
an inner panel having a front hem and a rear hem;
an outer panel separated from the inner panel by a cavity, the cavity including a reinforcement area;
a guard beam disposed in the cavity and extending laterally between the inner and outer panels above the reinforcement area, the guard beam extending across a speaker unit mounting hole of the inner panel, the reinforcing area being defined by the front hem, a floor of the vehicle door structure and the guard beam, the floor of the vehicle door structure having a bottommost surface of the cavity; and
a reinforcing member disposed in the reinforcement area and being positioned on the floor of the vehicle door structure below the guard beam, the reinforcing member being disposed substantially directly below the speaker unit mounting hole.

15. The vehicle door structure according to claim 14 , wherein
the inner panel includes a front part having the front hem and a rear part having the rear hem, the reinforcing member being disposed on both the front and rear parts.

16. The vehicle door structure according to claim 15 , wherein
the reinforcing member includes an inboard facing surface that contacts a stamped surface of the inner panel, an outboard facing surface that contacts the outer panel, a front hem facing surface that contacts the front hem, and a rear hem facing surface that contacts the rear part.
