[0006] Patent Document 1: JP-A-2011-63146 Summary of the invention

[0007] Technical issues

[0008] In the above conventional example, since the switch component is directly screwed to the switch base, the screwing position or screwing direction of the switch component is limited, so that restrictions on layout such as configuration of the switch component are increased.

[0009] In particular, since the opening formed on the outer panel of the rear door communicates with the interior of the vehicle, when the switch component is exposed to the outside from the opening, waterproof sealing around the opening must be considered, so that restrictions such as the configuration of the switch component are further increased.

[0010] According to the embodiments of the present invention, in the switch component mounting structure, restrictions on layout due to fixing of the switch component can be reduced.

[0011] Solution to the problem

[0012] According to an embodiment of the present invention, there is provided a switch component mounting structure for fixing a switch component 4 by exposing an operating portion 3 to the outer surface of a rear door 2 of a vehicle 1, the switch component mounting structure comprising: a switch base 8, which comprises a switch holding portion 5 for holding the switch component 4 and an insertion opening 6 on the switch holding portion 5 for inserting the operating portion 3 of the switch component 4, and is fixed to an outer panel 7 of the rear door 2; and a bracket 9, which is fixed to the switch base 8 and presses the switch component 4 in a fixed state so as to fix the switch component 4 to the switch holding portion 5.

[0013] According to an embodiment of the present invention, a switch base 8 is fixed to the outer panel 7 of the rear door 2. The switch member 4 is connected to the switch base 8 and fixed to the switch base 8 using a bracket 9 that presses the switch base 8 in a connected state.

[0014] Since the switch component 4 is fixed by pressing the bracket 9 instead of being directly fixed, the fixing position of the switch component 4 can be determined according to the situation, thereby reducing the restrictions on the layout.

[0015] According to an embodiment of the present invention, one end of the bracket 9 can be locked to a locking step 10 formed on the switch base 8, and the other end of the bracket can be connected and fixed to the switch base 8 in an appropriate manner, so that the middle part of the bracket can press the switch component 4 and fix the switch component 4.

[0016] According to an embodiment of the present invention, a locking step 10 is formed on the switch base 8, and the bracket 9 is fixed so that the other end thereof is connected to the switch base 8 by a screw or the like in a state where one end thereof is locked to the locking step 10. In the fixed state, the middle portion of the bracket 9 presses the switch component 4 so as to hold the switch component 4 at a predetermined position.

[0017] By connecting the other end of the bracket 9 in a state where one end thereof is locked, the fixing of the bracket 9, that is, the installation of the switch member 4, is completed, so that the installation workability is improved.

[0018] The bracket 9 may be locked at the free end or at the side edge near the free end, and the connection of the opposite end of the bracket 9 to the switch base 8 may be performed by a suitable means such as screws. In the case where the bracket 9 is elastically deformable, the bracket 9 is installed in an elastically deformed state, and the other end thereof is locked to the switch base 8, so that the bracket 9 can also be fixed to prevent detachment by using elastic restoring force.

[0019] According to an embodiment of the present invention, the bracket 9 may be formed of an elastic material in a plate shape, and may press the switch member 4 by an elastic restoring force in a fixed state.

[0020] When the bracket 9 presses the switch component 4, for example, by forming the abutment portion of the bracket 9 and the switch component 4 into an elastically deformable structure, the switch component 4 is pressed by the elastic restoring force of the abutment portion, thereby improving the click or the sealing performance to be described later. However, when the bracket 9 is formed of an elastic material (such as a metal plate material) and the switch component 4 is pressed using the elastic deformation of the bracket 9 itself, the structure can be simplified.

[0021] According to an embodiment of the present invention, the insertion opening 6 may be formed to communicate with the indoor space, and a sealing member 12 may be interposed between a sealing surface 11 formed on the periphery of the insertion opening 6 and a sealing surface formed on a corresponding portion of the switch component 4. In a state where the bracket 9 is fixed, the switch component 4 may be pressed in a direction to increase the sealing surface pressure of the sealing member 12.

[0022] Beneficial effects of the present invention

[0023] According to the embodiment of the present invention, since the switch component is fixed via the bracket, it is possible to reduce restrictions on layout compared to a case where the switch component is directly fixed by using screws or the like. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figure 1 (a) to 1(c) and Figure 2 As shown in FIGS. 2(a) and 2(b), the switch component 4 according to the present invention is used by being attached to the rear door 2 of the vehicle 1, and is arranged at an area covered by the trim 13 of the rear door 2. The switch component 4 is used as an operation switch of a door opener. When the operation portion 3 of the switch component 4 is pressed, a request signal is transmitted from the vehicle 1 to a portable device carried by a user, and when an authentication signal included in a response signal from the portable device with respect to the request signal is authenticated by an authentication device of the vehicle 1, an opening operation of the rear door 2 is performed by an actuator (not shown).

[0030] like Figure 2 As shown in FIGS. 2( a ) and 2 ( b ), in order to mount the switch member 4 , a switch attachment opening 7 a is provided on the outer panel 7 of the rear door 2 , and a switch base 8 is fixed to the switch attachment opening 7 a .

[0031] like Figure 2 As shown in FIGS. 2(a), 2(b) and 3, the switch base 8 includes an attachment flange 8a that abuts against the periphery of the switch attachment opening 7a of the above-mentioned outer panel 7, and a tubular body 8b that protrudes at the center portion of the attachment flange 8a and has a hollow truncated quadrangular pyramid shape that protrudes from the switch attachment opening 7a to the outside of the vehicle 1 to the outer panel 7 in a fixed state. The protruding end of the tubular body 8b is closed by a blocking wall 8c, and its hollow portion serves as a switch holding portion 5.

[0032] The locking step 10 is formed at the blocking wall 8c of the tubular body 8b, and the insertion opening 6 is formed in the bottom wall portion. In addition, a cylindrical bulge 8d protrudes from an extension of the bottom wall portion at the base end of the tubular body 8b, and a screw hole 8e is formed in the cylindrical bulge 8d. A sealing surface 11 corresponding to the sealing surface 11 formed on the switch component 4 to be described later is formed around the insertion opening 6.

[0033] like Figure 2 As shown in FIGS. 2(a) and 2(b), in the switch component 4, the switch component 4 is formed so that the button-shaped operating portion 3 protrudes from the switch housing. The operating portion 3 is arranged at one end of the switch housing, and the forked attachment 4a extends downward at the other end thereof. In addition, a sealing surface 11 is formed on the switch housing so as to surround the operating portion 3.

[0034] like Figure 2 As shown in FIGS. 2(a), 2(b), 3(c) and 3(d), the switch member 4 is configured in a posture in which the cylindrical bulge 8d of the switch base 8 is clamped from left and right by the attachment 4a, and the operating portion 3 is exposed from the insertion opening 6.

[0035] like Figure 2 As shown in (a) and 2(b), since the insertion opening 6 is connected to the indoor space, a sealing member 12 is inserted between a sealing surface 11 formed on the outer shell of the switch component 4 and a sealing surface 11 formed on the switch base 8 to prevent rainwater and the like from entering the room.

[0036] like Figure 5 As shown in FIGS. 5(a) to 5(c), the bracket 9 is used to hold the switch member 4 on the switch base 8, and is formed by bending a metal plate material into an L shape. One end of the bracket 9 is provided with a fastener insertion hole 9a corresponding to the screw hole 8e of the switch base 8, and the other end thereof is formed to have a size that can be locked to the locking step portion 10.

[0037] Therefore, in this embodiment, the switch component 4 is installed by holding the switch component 4 at a predetermined position with the seal member 12 interposed, that is, in a posture where the operation portion 3 is exposed from the insertion opening 6 , and then installing the bracket 9 .

[0038] The installation of the bracket 9 is as follows. Figure 2 As shown in (b), after one end of the bracket 9 is inserted into the opening of the switch holding portion 5 and its tip is locked to the locking step 10 of the switch base 8, the entire bracket 9 is locked around the locking portion with the locking step 10. Figure 2 In (b), the screw 14 is screwed into the screw hole 8e by rotating the screw 14 clockwise to align the fastener insertion hole 9a with the screw hole 8e.

[0039] In the state where the bracket 9 is mounted, the upper surface of the switch component 4 is pressed downward by the middle portion of the bracket 9. Therefore, appropriate sealing pressure is applied to the sealing member 12 to reliably prevent water from entering the vehicle from the insertion opening 6 and prevent the switch component 4 from rattling, etc.

[0040] As described above, the case where only the switch member 4 is held in the switch base 8 is shown, but the handle device may be rotatably connected. In this case, when the operating portion 3 of the switch member 4 is pressed, a request signal is transmitted from the vehicle 1 to the portable device carried by the user, and when an authentication signal included in a response signal from the portable device with respect to the request signal is authenticated by the authentication device of the vehicle 1, the locked state with respect to the locking device (not shown) holding the rear door 2 in the closed state is released, and then the handle is operated to release the latch of the locking device so that the door can be opened.
