  DESCRIPTION OF THE PREFERRED EMBODIMENTS The best mode for carrying out the present invention will be described below in detail based on the embodiments shown in the drawings. FIG. 1 is a schematic side view schematically showing an instrument panel monitor support structure 10 as an example of a support structure of a supported body, and FIG. 2 is a schematic side view schematically showing an impact absorption state of the monitor support structure 10 in the instrument panel. FIG. It should be noted that arrows FR and UP appropriately shown in the drawings respectively indicate the forward direction (traveling direction) and the upward direction of the automobile to which the instrument panel monitor support structure 10 is applied.

  As shown in FIG. 1, the in-instrument monitor support structure 10 supports a monitor 14 as a supported body with respect to the vehicle body inside the instrument panel 12 (in front of the passenger compartment). The monitor 14 is a device including at least a display function for displaying, for example, navigation information, vehicle information, and the like so as to be visible from the passenger compartment, and is disposed on the top of the instrument panel 12. An audio device 16 is disposed below the monitor 14 (center cluster portion).

  The in-instrument monitor support structure 10 includes a vehicle body side bracket 18 as a vehicle body side support member for supporting the monitor 14 with respect to the vehicle body, and a supported body side bracket 20 as a supported body side support member. The vehicle body side bracket 18 and the supported body side bracket 20 are provided on both sides of the monitor 14 in the vehicle width direction, respectively, and are basically configured in the same shape (substantially left-right symmetry). The vehicle body side bracket 18 and the supported body side bracket 20 will be described.

  The vehicle body side bracket 18 is formed in a substantially flat plate shape extending in the longitudinal direction of the vehicle body and in the vertical direction of the vehicle body as a whole, and is elongated along the substantially vertical direction of the vehicle body. The audio device 16 is fixedly attached by the fasteners 22. The supported-side bracket 20 is also formed in a substantially flat plate shape that extends in the longitudinal direction of the vehicle body and the vertical direction of the vehicle body as a whole, and is elongated along the vertical direction of the vehicle body. The monitor 14 is fixedly attached by the fastener 24.

  The lower end 18A in the longitudinal direction of the vehicle body side bracket 18 is fixedly attached to the vehicle body structure. As a vehicle body structure part, it can be set as the support bracket 28 etc. which were fixed to the dash panel, the dash cross member, or the instrument panel reinforcement 26, for example. A lower end portion 18 </ b> A of the illustrated vehicle body side bracket 18 is fixedly attached to a support bracket 28 fixed to the instrument panel reinforcement 26 via a connecting member 29.

  The lower end 20A in the longitudinal direction of the bracket 20 to be supported is fastened by a fastener 32 such as a screw at the upper end 18B in the longitudinal direction of the vehicle body side bracket 18 and in the vicinity of the upper surface of the audio device 16 in the side view shown in the figure. It is attached from the outside in the vehicle width direction. Accordingly, the supported-body-side bracket 20 is configured to be rotatable with respect to the vehicle-body-side bracket 18 around the attachment portion by the fastener 32.

  Further, the upper end portion 18B of the vehicle body side bracket 18 above the attachment portion by the fastener 32 is convex toward the outer side in the vehicle body width direction and is substantially elliptical and long in the longitudinal direction of the vehicle body side bracket 18. The to-be-fitted part 36 is formed. On the other hand, the lower end portion 20A of the supported body side bracket 20 and the upper side of the attachment portion by the fastener 32 are convex toward the outer side in the vehicle body width direction so as to be fitted to the fitted portion 36. A substantially elliptical fitting portion 38 that is long in the longitudinal direction of the supported-body-side bracket 20 is formed while the inner surface side is concave.

  By fitting the concave fitting portion 38 to the convex fitting portion 36 from the outside in the vehicle width direction, the supported body side bracket 20 can be held in a predetermined posture with respect to the vehicle body side bracket 18. . The fastener 32 is the attachment means 30 in the present invention, and the fitted part 36 and the fitting part 38 are the holding means 34 in the present invention. Further, the holding means 34 is arranged between the monitor 14 and the audio device 16 in the side view shown in the figure.

  Next, the operation of the instrument panel monitor support structure 10 configured as described above will be described. In the in-instrument monitor support structure 10 configured as described above, the pair of vehicle body side brackets 18 and the supported body side brackets 20 support the monitor 14 with respect to the vehicle body. For example, when a passenger collides with the monitor 14 at the time of a vehicle collision, and an impact load (a load of a predetermined value or more) is applied to the monitor 14 in the direction of arrow I (vehicle body side direction) shown in FIG. As shown in FIGS. 3 and 4, the supported-body-side bracket 20 is bent and deformed toward the outer side in the vehicle body width direction (the direction of arrow H shown in FIG. 4B) by the impact load, and the fitted portion 36 When the fitting part 38 is released from the position (the holding state by the holding means 34 is released), the monitor 14 moves downward in the vehicle body vertical direction (arrow D direction).

  Furthermore, when the impact load is transmitted to the support-side bracket 20, the monitor 14 maintains the state where the support-side bracket 20 is bent and deformed outward in the vehicle body width direction, and the fastener 32 (attachment means 30). The vehicle body pivots downward in the vertical direction of the vehicle body (in the direction of arrow S) (see FIGS. 3B and 4C). That is, the monitor 14 is secured with both a stroke that moves in the direction of the arrow D due to the bending deformation of the bracket 20 to be supported and a stroke that rotates in the direction of the arrow S around the fastener 32. Therefore, the impact load can be absorbed with a sufficient stroke without interfering with the audio device 16, and the impact load (peak load) acting on the occupant can be reduced.

  For example, in the in-instrument monitor support structure 100 as a comparative example shown in FIG. 5, the monitor 14 is supported with respect to the vehicle body by the bracket 102, so when an impact load in the direction of arrow I is applied to the monitor 14. The bracket 102 simply buckles in the vertical direction (longitudinal direction) of the vehicle body, and the monitor 14 interferes with the audio device 16 in the shock absorbing process due to the downward stroke indicated by the arrow L. For this reason, when the in-instrument monitor support structure 100 is applied, the audio device 16 must be disposed sufficiently away from the monitor 14, and there is a restriction on the arrangement of each part, and the space in the instrument panel 12 is limited. It becomes difficult to improve efficiency.

  On the other hand, in the instrument panel monitor support structure 10 according to the present embodiment, the monitor 14 can be moved in both the arrow D direction and the arrow S direction with respect to the input load in the arrow I direction as described above. Therefore, sufficient impact absorption performance can be ensured even in a narrow space without relying on measures to dispose the audio device 16 away from the monitor 14. Therefore, for example, the monitor 14 and the audio device 16 can be arranged close to each other in the vertical direction of the vehicle body, and the necessary gaps between the parts can be reduced, so that the space efficiency in the instrument panel 12 can be improved. it can. Moreover, since the freedom degree of arrangement | positioning of each component in the instrument panel 12 can be improved by this, the freedom degree of a design can also be improved.

  As described above, according to the instrument support structure 10 in the instrument panel according to the present embodiment, it is possible to secure a sufficient shock absorbing stroke (shock absorbing performance) and to improve the degree of freedom of arrangement of each component such as the monitor 14 and the audio device 16. Can be made compatible. In addition, the shape of the to-be-fitted part 36 and the fitting part 38 which comprise the holding means 34 is not limited to the shape shown in FIGS. 1-4, For example, it is good also as a hemispherical shape as shown in FIG. . For example, as shown in FIG. 7, the fitted portion 36 and the fitting portion 38 may be formed in a convex shape inward in the vehicle body width direction. That is, the convex fitting portion 38 may be fitted to the concave fitting portion 36 from the outside in the vehicle width direction.

  In any case, the material, thickness, width, etc. are set so that the supported-side bracket 20 can be bent and deformed by a collision load applied to the monitor 14, and the holding state by the holding means 34 is thereby set. It is only necessary to be configured to be easily released (the fitting portion 38 is easily detached from the fitted portion 36). Furthermore, it is only necessary that the shock absorbing stroke direction of the monitor 14 can be easily set to a direction that does not interfere with the audio device 16.

  Further, the posture restraining force (by the fitted portion 36 and the fitted portion 38) by the holding means 34 is determined by the length and depth of the fitted portion 36 and the fitted portion 38 in the longitudinal direction (the vehicle body vertical direction). Accordingly, the amount of deformation of the support-side bracket 20 can be controlled by this, and the shock absorbing stroke direction of the monitor 14 can be controlled. Incidentally, when the lengths of the fitted portion 36 and the fitting portion 38 are short, the bending deformation amount is small, and when the length is long, the bending deformation amount is large. And if the depth of the to-be-fitted part 36 and the fitting part 38 is shallow, a bending deformation amount will become small, and if it is deep, a bending deformation amount will become large.

  Further, the bending deformation direction of the supported-body-side bracket 20 is not limited to the outer side in the vehicle body width direction (arrow H direction), and is configured to bend and deform in the vehicle body width direction inner side (direction opposite to the arrow H direction). Also good. As described above, the bending deformation and the rotation direction of the supported-body-side bracket 20 may be appropriately set according to the positional relationship between the monitor 14 and its peripheral components, and are not limited to the above embodiment.

  Moreover, in the said embodiment, although the attaching means 30 was used as the fasteners 32, such as a screw, the attaching means 30 is not limited to this, For example, you may carry out the spot welding etc. (1 point) which are not shown in figure. Moreover, although the example which supports the monitor 14 as a to-be-supported body in the instrument panel 12 was shown in the said embodiment, this invention is not limited to this, The structure which supports various to-be-supported bodies with respect to a vehicle body is shown. Can be applied.
