[0010]
DETAILED DESCRIPTION OF THE INVENTION
A vehicle internal door handle device mounting structure according to an embodiment of the present invention will be described in detail with reference to the drawings. The vehicle inside door handle device mounting structure 1 of the present embodiment is disposed on the inner surface side of the vehicle door, and the vehicle inside door handle device that opens and closes the door when operated by a passenger is used as the door. It is a structure to install.
[0011]
FIG. 1 is a front view of an inside door handle device 10 having an inside door handle device mounting structure according to this embodiment. FIG. 2 is a side view of the inside door handle device mounting structure 1 according to this embodiment. It is sectional drawing in alignment with the centerline of the longitudinal direction. FIG. 3 is a view showing a state in which an impact is applied to the state of FIG. 2 and the door trim 40 is separated from the door panel 30. The inside door handle device 10 includes a handle base 11 fixed to the door panel 30 and the door trim 40, and a base end side 12 a rotatably supported on the handle base 11 by a support shaft 17, while the handle base 11 side is supported by a winding spring 18. The operation handle 12 is biased and held, and the lock knob 19 locks and unlocks the door lock 35 while being rotatably supported on the handle base 11 by the support shaft 17. One end of the lock wire 34 is fixed to the proximal end of the operation handle 12, and the door lock 35 coupled to the lock wire 34 is engaged / released by operating the operation handle 12. .
[0012]
A panel fixing portion 13 for fixing the inside door handle device 10 to the door panel 30 is provided at the center portion of the handle base 11. Further, the handle base 11 is provided with a trim fixing portion 14 that extends outward from the outer periphery thereof and fixes the inside door handle device 10 to the door trim 40.
[0013]
And the attachment structure 1 of the vehicle inside door handle apparatus of this embodiment is a panel side, inserting the screw 33 in the insertion hole 13a provided in the panel fixing | fixed part 13, as FIG. 2, FIG. 5 shows. A screw 33 is screwed into a screw hole 32 provided in the fixing portion 31 to fix the inside door handle device 10.
[0014]
The first trim coupling portion 20a includes a trim fixing portion 14 in which a substantially tuning fork shape portion 15 divided into two branches is formed at a tip portion, a trim side fixing portion 41, and a screw 43 as a fixing member. ing. Then, by inserting the screw 43 between the crotch of the substantially tuning fork shape portion 15 and screwing it into the screw hole 42 of the trim side fixing portion 41, between the head 43 a of the screw 43 and the trim side fixing portion 41. A substantially tuning fork shape portion 15 is sandwiched and the handle base 11 is fixed to the door trim 40.
[0015]
Further, the handle base 11 is screwed into the screw holes 32 of the panel-side fixing portion 31 while the screws 33 are inserted into the insertion holes 13a provided in the panel fixing portion 13 provided in the center portion. Is fixed to the door panel 30.
[0016]
Thus, when the door trim 40 is separated from the door panel 30, as shown in FIG. The screw base 43 is slid so that the handle base 11 is separated from the door trim 40 without falling off the door panel 30.
[0017]
Further, as shown in FIG. 4, a notch 16 is provided at the base end portion of the trim fixing portion 14 'constituting the second trim coupling portion 20b. Accordingly, when the door is deformed by receiving an impact from the outside, the trim fixing portion 14 ′ is broken starting from the notch 16, so that the handle base 11 can be reliably separated from the door trim 40.
[0018]
With the above configuration, the first trim coupling portion 20a is configured to sandwich the tip end portion of the trim fixing portion 14, so that when receiving an impact with a relatively simple structure without increasing the manufacturing cost. The inside door handle device 10 can be separated from the door trim 40 without falling off the door panel 30, and the notch 16 is provided in the base end portion of the trim fixing portion 14 'as the second trim coupling portion 20b. The inside door handle device 10 can be reliably separated from the door trim 40 without dropping from the door panel 30 when receiving an impact without increasing the manufacturing cost with a relatively simple structure. Therefore, when the door trim 40 is separated from the door panel 30 due to an impact, the inside door handle device 10 is cut off from the door trim 40, so that the door lock 35 is unlocked by pulling the lock cable linked to the operation handle 12. Can be prevented.
[0019]
In the present embodiment, the first trim coupling portion 20a and the second trim coupling portion 20b are provided, but a notch is formed in the root portion of the trim side fixing portion of the door trim as the third trim coupling portion. By doing so, the trim-side fixing portion is separated from the root portion when subjected to an impact, and the same effect can be obtained.
[0020]
【The invention's effect】
According to the first aspect of the present invention, the trim connecting portion is divided when an impact is applied to the door panel, so that the door panel is impacted as in a side collision, and the door trim is separated from the door panel. In this case, since the handle base is separated from the door trim, it is possible to prevent the door lock from being unlocked by pulling the lock cable linked to the inside door handle device.
[0021]
Further, since the trim coupling portion has a relatively simple structure, the handle base can be dropped from the door trim when subjected to an impact without increasing the manufacturing cost.
[0022]
According to the second aspect of the present invention, in addition to the effect of the first aspect of the present invention, a notch is provided in the base end portion of the trim fixing portion that constitutes the trim coupling portion, thereby producing a relatively simple structure. The handle base can be removed from the door trim when subjected to an impact without increasing the cost.
