[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for an in-vehicle device, for example, to a mounting structure suitable for application to mounting an audio device such as a tuner or a speaker to a vehicle body strength member such as a steering support member of an automobile.
[0002]
[Prior art]
8 and 9 show a conventional mounting structure for mounting the audio device 2 in the instrument panel 1 of the automobile and mounting it on the vehicle body side. In the case of this conventional example, a support member 4 having a substantially U-shaped cross section, for example, is erected by welding or the like on a steering support member (a pipe member installed between a pair of left and right front pillars) of a vehicle as a vehicle body strength member. On the other hand, the bracket 5 having a substantially U-shaped cross section is attached to the audio device 2 so as to correspond to the both side surfaces 2a, 2b and the rear end surface 2c of the audio device 2. Further, a pin 7 is erected substantially at the center of the rear end portion 5a of the bracket 5 corresponding to the rear end surface 2c of the audio device 2, and a bush 8 is coaxially mounted around the pin 7.
[0003]
Thus, when attaching the audio device 2 to the vehicle body side, hold the front portion of the audio device 2 by hand and insert the rear portion of the audio device 2 into the audio device accommodation opening 9 of the instrument panel 1 from the rear side of the vehicle body. 9, the audio device 2 is moved to the front side of the vehicle body as indicated by an arrow R, and the pin 7 and the bush 8 are inserted into the engagement hole 10 provided at the upper end of the support member 4, whereby the rear portion of the audio device 2 is moved. It is attached to the upper end of the support member 4. Next, a pair of mounting pieces 11 made of bent pieces respectively provided on both side portions of the bracket 5 are applied to the peripheral edge portion 12 (see FIG. 9) of the audio device accommodation opening 9 of the instrument panel 1 and screw or screw. The front part of the audio device 2 is attached to the instrument panel 1 by being fastened and fixed at 13.
[0004]
[Problems to be solved by the invention]
However, the conventional mounting structure as described above has the following various problems. First, when the audio device 2 is attached, the operator can hold only the front portion of the audio device 2 by hand, so that there is a problem that it is difficult to stably hold the audio device 2 and the workability is poor. Further, since the operator cannot visually check the engagement hole 10 of the support member 4 during the mounting operation of the audio device 2, the operation of inserting the pin 7 and the bush 8 into the engagement hole 10 is a so-called “blind operation”. It must be done and the work is cumbersome.
[0005]
Further, since the rear portion of the audio device 2 is supported by attaching the center portion of the rear end surface 2c of the audio device 2 to the upper end portion of the support member 4 as shown in FIG. For an audio device that is long) or an audio device of a type in which the wire harness is pulled out from the center of the rear end surface, the mounting structure using the support member 4 as described above cannot be employed. Therefore, in the conventional mounting structure as described above, there are restrictions on the audio devices that can be mounted, and it is actually impossible to mount a wide variety of audio devices.
[0006]
Moreover, since it is necessary to make the attachment strength (rigidity) of the support member 4 weaker than usual so that the audio device 2 arranged on the instrument panel 1 can absorb impact energy, the support of the audio device 2 is required. May become unstable and may cause problems such as vibration of the audio device 2 while the vehicle is running.
[0007]
The present invention has been made in view of such problems, and the object thereof is limited by the size (length of the depth) of an in-vehicle device such as an audio device or the like and the drawing position of the wire harness. It can be installed without any problem, can improve the workability and assembly accuracy of the in-vehicle equipment, and has sufficient impact energy absorption function while ensuring sufficient mounting strength of the in-vehicle equipment. It is to provide a mounting structure for a vehicle-mounted device.
[0008]
[Means for Solving the Problems]
In order to achieve the above-described object, in the present invention, an instrument panel is disposed at a front portion of a vehicle interior, and brackets are attached to both side surfaces of an in-vehicle device on a pair of support members attached to a vehicle body strength member. In the mounting structure of an in-vehicle device of an automobile that fixes the in-vehicle device via a pin, a pin and a bush attached to the pin are attached to a free end portion of the bracket on the vehicle front side, and a flange is provided on the support member. The flange is provided with a locking portion for locking the pin via the bush, and the bush is locked to the locking portion to support the in-vehicle device on the support member, while the vehicle interior side of the bracket is mounted on the instrument It is intended to be fixed to the instrument panel.
Further, in the present invention, the locking portion of the support member is configured by a flange that is inclined with respect to the axis of the pin and the bush, and the contact portion between the tip of the flange that forms the locking portion and the bush, The bent portion of the free end portion of the bracket where the pin and the bush are disposed is offset in the vehicle width direction.

It is arranged in a state of being inclined toward the rear side of the vehicle body as it goes from the base of the head toward the tip.
[0014]
On the other hand, as shown in FIGS. 2 to 4, brackets 23 each having an attachment piece 22 at one end are attached to both side surfaces 2 a and 2 b of the audio device 2 so as to extend in the front-rear direction of the audio device 2 ( However, the bracket 23 on the side surface 2b is not shown). And the front-end | tip of this bracket 23, ie, the edge part on the opposite side to the said attachment piece 22, and the edge part arrange | positioned at the vehicle body front side is made into the free end part 24. As shown in FIG. More specifically, as shown in FIG. 6, a protruding portion 26 is provided at the front end edge of the bracket 23 so that the concave portions 25 are disposed corresponding to the side surfaces 2 a and 2 b of the audio device 2. When the bracket 23 is attached to the both side surfaces 2a and 2b, the pin mounting piece 26a provided on the protruding portion 26 is at a position (offset position) away from the both side surfaces 2a and 2b of the audio device 2. At the same time, the front end 23a of the bracket 23 is placed in contact with the both side surfaces 2a and 2b without being constrained. As a result, the free end 24 of the bracket 23 is provided with a bent portion (foldable portion) M at the vehicle body rear side portion of the concave portion 25 facing the tip portion 23a.
[0015]
The head portion 27a of the pin 27 is disposed in the concave portion 25 of the bracket 23, and the shaft portion 27b of the pin 27 is disposed so as to protrude outward from the protruding portion 26 of the bracket 23. Further, the shaft portion 27b. A bushing 28 is coaxially mounted around the periphery of the.

Further, the flange portion β constituting one end side of the flange 18a of the support members 16a and 16b is provided as a locking portion W for locking the pin 27 and the bush 28 attached to the audio device 2 side as described above. It has been. In other words, the locking portion W is configured by a flange portion β that is inclined with respect to the axis of the pin 27 and the bush 28, and as shown in FIG. The contact portion (bush support portion) N between the tip of β and the bush 28 and the bent portion M of the free end 24 of the bracket 23 where the pin 27 and the bush 28 are disposed are offset in the vehicle width direction (offset). Distance L).
[0017]
Next, the installation work of the audio device 2 will be described as follows. First, the pair of support members 16a and 16b are fixed to the steering support member 3 by fastening means such as welding, and the support members 16a and 16b are opposite to each other and the flanges 18a, 18b and 19 are directed outward. They are arranged opposite to each other in parallel. As a result, the support members 16a and 16b are connected to the steering support in the state where the fastening portions of the rear portions on both sides and the front portions on both sides of the audio device 2, that is, the engaging portion W including the flange portion β and the mounting piece 24 are integrated. Secure to member 3.
[0018]
Then, the audio device 2 is inserted into the opening 9 of the instrument panel 1 from the rear side, and the pins 27 and the bushes 28 respectively disposed on both side surfaces 2a and 2b of the audio device 2 are connected to the support members 16a and 16b. It is placed on the flange portion α of the flange 18a. Next, by applying a force for pushing the audio device 2 toward the front side of the vehicle body, the pin 27 and the bushing 28 are moved along the flange portion α while moving toward the front side of the vehicle body, so that the bushing 28 is supported by the support members 16a, 16a, The flange portion β of the flange 16a of 16b is engaged. That is, the pin 27 and the bush 28 are guided (guided) by the flange portion α, and brought into contact with the inclined flange portion β (locking portion W) connected thereto. In this case, since the flange portion β constituting the engaging portion W is inclined toward the rear side of the vehicle body, as shown in FIG. 6, the peripheral surface of the bush 28 is in a state of being in line contact with only the leading edge of the flange portion β. At the same time, the flange portion β as the engaging portion W is disposed in an inclined state with respect to the axis of the pin 27 and the bush 28 (see FIGS. 5 and 6).
[0019]
Under such a state, the upper end portion of the mounting piece 22 of the bracket 23 is fastened and fixed to the peripheral edge portion 12 of the opening 9 of the instrument panel 1 with screws or screws 29, and the mounting pieces of the support members 16a and 16b are fixed. The peripheral edge 12 of the opening 9 is sandwiched between 20 and the mounting piece 22 of the bracket 23, and these are fastened together with screws or screws 30. As a result, the front and rear portions of both side surfaces 2a and 2b of the audio device 2 are fixed to the steering support member 3 and the instrument panel 1 via the pair of support members 16a and 16b.
[0020]
According to the mounting structure of the audio device 2 having such a configuration, when the audio device 2 is assembled, the pin 27 and the bush 28 on the audio device 2 side are mounted on the flange portion α of the flange 18a of the support members 16a and 16b. Since the bush 28 may be engaged (contacted) with the flange portion β of the flange 18a of the support members 16a and 16b, the flange portion α is connected to the pin 27 and the bush 28. It can be used as a guide. Therefore, the audio device 2 can be easily and reliably moved to a predetermined assembly position without being supported by a hand or the like.
[0021]
The audio device 2 is held by a single member (a single member to which no other member is attached in addition to the plate-like member) of the pair of support members 16a and 16b fixed to the steering support member 3. Therefore, the assembly accuracy of the audio device 2 can be improved.
[0022]
In addition, the audio device 2 can be mounted independently of the rear end surface 2c of the audio device 2 because the place where the audio device 2 is supported is changed from the center portion of the conventional rear end surface to both side surfaces 16a and 16b. Therefore, there is no restriction on the rear end face 2c. Specifically, there is no restriction on the size (depth length) of the audio device 2 and the drawing position of the wire harness 31 (see FIG. 2), and the degree of freedom for these can be improved. it can. Therefore, it is possible to attach various audio devices 2 as necessary.
[0023]
Further, in the present embodiment, the bent portion M of the mounting portion of the pin 27 and the bush 28 at the free end 24 and the bush contact portion (support location) N of the flange portion β of the support members 16a and 16b are the vehicle width. Since it is offset in the direction, the pin 23 of the bracket 23 and the free end portion 24 which is the bush mounting portion are easily deformed at the time of impact action. Accordingly, when an excessive impact force is applied to the audio device 2 in the direction indicated by the arrow F in FIG. 6 (the direction toward the front of the vehicle body), the flange 23 bends at the folding point M as shown in FIG. Impact energy can be absorbed by bending. Therefore, an impact energy absorbing function can be provided without lowering the rigidity of the bracket 23 that holds the audio device 2, and a structure that is effective against vibration associated with vehicle travel can be provided.
[0024]
Further, since the rubber bush 28 is attached to the pin 27, it is possible to facilitate the work during the assembly work of the audio device 2 and to prevent the vibration after the audio device 2 is attached. That is, if the pin 27 is slid on the flange portion α of the bracket 23 without mounting the bush 28, the sliding occurs in a state in which the metal rubs, and smooth sliding cannot be performed. Even after the audio device 2 is mounted, vibration noise (metal sound) is generated between the metal of the pin 27 and the flange portion β of the bracket 23 as the vehicle travels. If the bush 28 is attached to the flange portion α, β and the bush 28 are in contact with each other with a metal material and a rubber material, the bush 28 is attached to the flange portion α when the audio device 2 is attached. The top can be slid smoothly, and the generation of vibration noise after the audio device 2 is attached can be effectively prevented.
[0025]
Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and various modifications and changes can be made based on the technical idea of the present invention. For example, in the above-described embodiment, the audio device 2 is attached to the steering support member 3, but various in-vehicle devices other than the audio device 2 (wireless receivers, electronic control devices, etc.) The present invention can also be applied to the case where it is attached to a vehicle body strength member.
[0029]
