BACKGROUND OF THE INVENTION
The present invention relates to a door handle reinforcement structure that can improve the strength of a door handle mounting portion of an automobile and can effectively prevent a door lock from being released by inserting a tool from the vicinity of the door handle mounting portion.
[0002]
[Prior art]
A door handle for opening and closing a door of an automobile is usually disposed on a door outer panel or a door license panel constituting a part of the door outer panel. As shown in FIG. 10, the handle attachment surface 105 of the door license panel 103 to which the door handle is attached is conventionally provided with a rear surface of the handle attachment surface 105 so as not to bend when the door handle 101 is operated. By arranging the handle reinforcing plate 107 on the side, the strength of the handle mounting surface 105 of the door license panel 103 is improved.
However, in the handle reinforcing plate 107 having such a conventional structure, there is a possibility that the deflection of the handle mounting surface 105 of the door license panel 103 cannot be reliably suppressed when a large load is applied to the door handle.
[0003]
On the other hand, some back doors of automobiles are provided with a door handle in the vicinity of a license lamp provided on the top of the license plate. In the back door having such a structure, after removing the license lamp, a driver or the like is inserted from the mounting hole of the license lamp, the door lock is released, and not only the intrusion into the vehicle interior but also the damage of the vehicle theft. There is a risk of suffering. In order to prevent this damage, for example, the following measures are taken.
(1) Like the back door 121 shown in FIG. 10, the license lamp 109 is fixed from the indoor side, and the license lamp 109 cannot be removed from the outdoor side.
(2) Like the back door 123 shown in FIG.
[0004]
However, depending on the measure (1), the mounting portion 135 including the bolt 131 and the nut 133 for mounting the license lamp 109 is increased, and the degree of freedom in design is reduced. Further, since the license lamp 109 is assembled with the bolt 131 and the nut 133, the number of assembling work steps is increased.
Further, depending on the measure (2), the harness 137 of the license lamp 109 needs to be disposed on the indoor side, so that the tool entry path cannot be completely blocked. In addition, new parts are required, which increases costs and assembly man-hours.
