Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0014]
FIG. 1 is a rear view of a vehicle door handle device 1 of the present embodiment assembled to a vehicle as viewed from the back side of the door panel 50, and FIG. 2 is a cross-sectional view taken along line AA shown in FIG. 3 is a cross-sectional view taken along line BB shown in FIG. 1, and FIG. 4 is a cross-sectional view taken along line CC shown in FIG.
[0015]
As shown in FIGS. 1 to 3, the vehicle door handle device 1 of the present embodiment is fixed to a mounting portion 51 provided on an outer door panel 50 of the vehicle.
[0016]
The vehicle door handle device 1 includes a thermoplastic resin handle case 10 provided with a cylinder lock 40 as a lock portion for locking and unlocking a lock mechanism (not shown) disposed inside the door panel 50. And an anti-theft bracket 30 as shown in FIG. 5 as a bracket, and a door handle 20 that is operably disposed on the handle case 10 and is connected to a lock mechanism. Is opened and closed.
[0017]
The anti-theft bracket 30 is sandwiched between a first panel fixing boss 12 as a boss portion protruding from the back surface 11 of the handle case 10 toward the inside of the door panel 50 and the fixing member 14.
[0018]
The fixing member 14 has a substantially nut shape including a flange portion 14a as a co-tightening portion on one end side and an internal thread portion 14b on the inner surface of a fixing portion 14d provided on the other end side.
[0019]
The fixing member 14 has an outer peripheral surface 14c of the fixing portion 14 fixed to the first panel fixing boss 12 by a heat welding method. When the fixing member 14 is heated and fixed to the first panel fixing boss 12, the anti-theft bracket 30 is sandwiched between the flange portion 14 a and the first panel fixing boss 12.
[0020]
Further, a first fixing portion 42 of a cylinder lock 40 as another member and an attachment portion 51 of the door panel 50 are fixed to a female screw portion 14 b provided on the inner surface of the fixing member 14 by a bolt 44.
[0021]
The anti-theft bracket 30 is formed of a plate-like member having an accommodating portion 31 that accommodates the cylinder lock 40, a boss fixing hole 35, a cylinder fixing hole 36, a position restricting hole 32, and a position restricting groove 33. The anti-theft bracket 30 is provided with a wall 34 along the outer periphery of the handle case 10 to improve the deformation strength against an unauthorized external force.
[0022]
The anti-theft bracket 30 is fixed to the handle case 10 by fixing the boss fixing hole 35 to the first panel fixing boss 12 and fixing the cylinder fixing hole 36 to the cylinder fixing boss 17.
[0023]
Further, the locating pin 15 provided in the handle case 10 is inserted into the position restricting hole 32, and the position restricting protrusion 16 provided in the first panel fixing boss 12 is inserted into the position restricting groove 33 provided in the boss fixing hole 35. By being locked, the assembly position of the anti-theft bracket 30 is defined.
[0024]
A nut 18 is embedded in the cylinder fixing boss 17, and the anti-theft bracket 30 is fixed to the cylinder fixing boss 17 by being fastened to the nut 18 by a bolt 43 together with the first fixing portion 41 of the cylinder lock 40. Yes.
[0025]
As shown in FIGS. 1 and 4, the wire bracket 30 ′ includes a second panel fixing boss 13 projecting from the back surface 11 of the handle case 10 toward the inside of the door panel 50, and a fixing member 14 ′. Is sandwiched between.
[0026]
The fixing member 14 'has a substantially nut shape having a flange portion 14a' as a co-tightening portion on one end side and an internal thread portion 14b 'on the inner surface of a fixing portion 14d' provided on the other end side.
[0027]
The fixing member 14 ′ has an outer peripheral surface 14 c ′ of the fixing portion 14 ′ fixed to the second panel fixing boss 13 by a heat welding method. When the fixing member 14 ′ is heated and fixed to the second panel fixing boss 13, the wire bracket 30 ′ is sandwiched between the flange portion 14 a ′ and the second panel fixing boss 13.
[0028]
Further, a mounting portion 51 ′ of the door panel 50 as another member is fixed to a female screw portion 14 b ′ provided on the inner surface of the fixing member 14 ′ with a bolt 44 ′.
[0029]
The wire bracket 30 ′ supports a wire 52 routed inside the door panel 50, and includes a boss fixing hole 35 ′ fixed to the second panel fixing boss 13, a position restricting groove 33 ′, and a wire 52. It is formed from a plate-like member having a supporting wire support portion 37 '.
[0030]
The wire bracket 30 ′ is fixed to the handle case 10 by fixing the boss fixing hole 35 ′ to the second panel fixing boss 13.
[0031]
Further, the position restricting groove 33 ′ is engaged with a plate-like restricting protrusion 16 ′ provided on the handle case 10, whereby the assembly position of the wire bracket 30 ′ is defined.
[0032]
Therefore, the handle case 10 is fixed to the door panel 50 at the two positions of the first panel fixing boss 12 and the second panel fixing boss 13.
[0033]
With the above configuration, when the fixing member is welded to the handle case, the anti-theft bracket is sandwiched between the fixing member and the boss, thereby reducing the number of parts for assembling the anti-theft bracket and reducing the number of assembly steps. In addition, the manufacturing cost can be reduced.
[0034]
Since the female screw portions 14b and 14b 'are formed as the fixing portions of the fixing members 14 and 14', they are generally used when fixing the fixing portion 42 of the cylinder 40 and the mounting portions 50 and 50 'as other members. Since it is possible to use bolts and screws that have been used, manufacturing costs can be reduced by sharing parts.
[0035]
Further, since the vehicle door handle device 1 is assembled to the door panel 50 in a state where the anti-theft bracket 30 and the wire bracket 30 'are fixed, the number of parts to be fastened together with the mounting portions 51 and 51' can be reduced. it can. As a result, complicated work is simplified, and the number of assembling work steps for the vehicle body can be reduced.
[0036]
In the present embodiment, the thermal welding method is used when welding the boss portions 12 and 13 and the fixing member 14, but the same effect can be obtained even if an ultrasonic welding method using ultrasonic vibration is used. it can.
[0037]
Moreover, when welding the 1st boss | hub part 12 and the fixing member 14, it is possible to improve the fastening intensity | strength of the anti-theft bracket 30 by welding the anti-theft bracket 30 together to the 1st boss | hub part 12. FIG. .
[0038]
In this embodiment, a substantially nut-shaped member having flange portions 14a and 14a 'is used for the fixing members 14 and 14', but a substantially stud bolt having a flange portion on one end side and a male screw portion on the other end side. A similar effect can be obtained by using a member having a shape and fastening another member to the male screw portion using a nut or the like.
[0039]
In addition, as a fixing member, a member having a flange portion on one end side and a round bar portion on the other end side is used, and the other member is rotatably supported on the round bar portion using a push nut or the like. The effect of can be obtained.
[0040]
Furthermore, a substantially cylindrical member provided with a flange portion is used as the fixing member, and the same effect can be obtained by fastening another member to the hole provided inside by a tapping screw or the like.
[0041]
In the present embodiment, the case where the anti-theft bracket 30 and the wire bracket 30 ′ are assembled to the full escutcheon type vehicle door handle apparatus 1 is shown, but the anti-theft bracket and the wire are attached to the grip handle type vehicle door handle apparatus. Even when the bracket 30 'is assembled, the same effect can be obtained.
