[0030] Fig. 10 is a front view showing a second embodiment of the present invention. Hereinafter, the same reference numerals are given to the same structures as those of the first embodiment in FIG. 10 , and repeated descriptions will be omitted. As shown in FIG. 10 , the door 1 ′ of the present embodiment has an auxiliary door latch 15 added as a fourth connecting portion located under the vehicle of the locking portion 9 . The inner panel 4' These protrusions cross each other in approximately the middle of the inner panel 4' to form an X-shaped protrusion pattern. An auxiliary door latch 15 is added to enhance the connection between the door 1 and the vehicle body 2, and the auxiliary door latch 15 is a well-known mechanism capable of connecting and releasing the door 1 and the vehicle body. Furthermore, the door 1'

Abstract

A vehicle door structure comprises an inner panel (4) provided with an upper hinge (7), a lower hinge (8) and a lock portion (9) that are disposed on sides of a perimeter of a door (1) that are different from each other so as to couple the door (1) and a vehicle body (2). The inner panel (4) is reinforced by two beads (20, 20) that extend so as to substantially connect the lower hinge (8) and the lock portion (9), and that protrude inward in the lateral direction of the vehicle, and by two subsidiary beads (21, 21) that branch from a substantially central portion of a bead (20) and extend toward the upper hinge (7), and that protrude inward in the lateral direction of the vehicle.

Description

technical field [0001] The present invention relates to vehicle door structures. Background technique [0002] As a door structure provided for a vehicle, there is a structure in which a reinforcing beam extending from an upper hinge of a side door or from its vicinity toward a door lock striker is mounted to an inner panel by spot welding (for example, PCT International Application No. 2004- 520224 Japanese translation). [0003] The above-mentioned door structure is designed so that in the event of a side collision of the vehicle, the reinforcing beam can bear the collision load input to the door and transmit it to the vehicle body pillar. However, adding reinforcement beams increases the weight of the door and increases the man-hours required to install the reinforcement beams. In addition, considering the need to secure the space required to install various devices in the door, there is a concern that adding a reinforcing beam will lead to an increase in the thickness ...
