Description

[Technical field]

[0001] The present invention relates to a structure of an instrument panel. [Background technology]

[0002] Some vehicle instrument panels have a layout in which vehicle operation switches are lined up directly below the audio equipment mounted on the instrument panel, and this causes the harnesses for these switches to come into contact with the audio equipment or the audio mounting bracket, causing friction and deterioration. In addition, in the case of a layout in which the audio equipment and the switches are lined up side by side, the opening for mounting the audio equipment and the opening for mounting the switches are shared, resulting in a problem that the opening provided in the instrument panel becomes large. Therefore, among conventional instrument panel structures, there is a structure that prevents the audio harness from getting caught by inserting it through an opening in the instrument panel when assembling the audio equipment to the instrument panel (see, for example, Patent Document 1).

[0009] Hereinafter, the present invention will be described in detail based on the illustrated embodiments. 1 to 4 show the structure of an instrument panel according to an embodiment of the present invention. In the drawings, the arrow Fr direction indicates the front of the vehicle, the arrow O1 direction indicates the right side outward of the vehicle, the arrow O2 direction indicates the left side outward of the vehicle, and the arrow U direction indicates the top of the vehicle. The arrow X direction indicates the width direction of the vehicle, and the arrow Y direction indicates the front-rear direction of the vehicle.

[0010] As shown in Figures 1 to 4, the instrument panel 1 of a vehicle to which the structure of the embodiment of the present invention is applied is a large resin molded part on which various on-board devices are mounted, and is provided at the front side of the vehicle interior and arranged across the entire width of the vehicle in the vehicle width direction. A steering support member 2 extending along the vehicle width direction is arranged inside the instrument panel 1, and the instrument panel 1 is supported by the steering support member 2 and attached to a dash side panel (not shown) constituting a vehicle body side part via the steering support member 2. An opening 4 for attaching audio equipment 3 and vehicle operation switches (not shown) is provided at approximately the center of the instrument panel 1 in the vehicle width direction, and the opening 4 is formed to a size and shape that allows the audio equipment 3 and vehicle operation switches (not shown) to be attached.

[0011] 2 to 4, the opening 4 of this embodiment has a lower wall 5 extending from the opening lower edge 4a toward the front of the vehicle. This lower wall 5 extends toward the steering support member 2 located further forward of the general surface of the instrument panel 1 facing the interior of the vehicle. Due to the presence of the lower wall 5, the opening 4 is configured to have improved torsional rigidity. Further, the lower wall 5 is provided with a first wall portion 51 extending from a front end portion 5a of the lower wall 5 toward the upper portion of the vehicle, and an insertion hole 50 for inserting a harness (wire harness) 6 of a vehicle operation switch (not shown) is provided in an approximately central portion of the first wall portion 51 in the vehicle width direction. This insertion hole 50 extends in the insertion direction of the harness 6 (inside the instrument panel 1) and is formed by a wall portion 50a surrounding the harness 6. In other words, the insertion path of the harness 6 is surrounded on all four sides by the wall portions 50a and the first wall portion 51, so that the harness 6 does not come into contact with and rub against surrounding components, deterioration of the harness 6 is prevented, and the rigidity of the instrument panel 1 is ensured.

[0012] In the structure of the instrument panel 1 of this embodiment, an inner opening 8 for mounting audio equipment 3 via a bracket 7 is provided at the center inside the opening 4, as shown in Figures 1 to 4. The bracket 7 is disposed spaced apart in the vehicle width direction, has opposing walls 70 positioned opposite each other on the left and right sides, and has a first fixing portion 71 and a second fixing portion 72 fixed to the lower wall 5. Inside the opening 4, on both the left and right sides of the inner opening 8, openings 9 for mounting louvers are provided. The inner opening 8 of this embodiment has a rectangular shape in a front view of the vehicle, and is formed by an upper wall 81 and a lower wall 5 located at the top and bottom in the vehicle vertical direction, and a left side wall 82 and a right side wall 83 located at the left and right in the vehicle width direction. The left side wall 82 and the right side wall 83 are each provided at their front ends 82a, 83a with a member fixing portion 84 that extends in a cylindrical shape with an upper opening toward the front of the vehicle and is fixed to the steering support member 2 by a fastener or the like, and the member fixing portion 84 is located between the first fixing portion 71 and the second fixing portion 72 in a front view of the vehicle. That is, the first fixing portion 71 is provided at a position where the front end lower portion 70a of the opposing wall 70 is bent toward the inside of the vehicle, and the second fixing portion 72 is provided at a position where the rear end lower portion 70b of the opposing wall 70 is bent toward the outside of the vehicle. By providing such a bracket 7 inside the inner opening 8, the torsional rigidity of the inner opening 8 is improved, deformation during installation of the audio equipment 3 is suppressed, and the gap between the audio equipment 3 and the instrument panel 1 is stably maintained. In addition, the bracket 7 has a third fixing portion 73 which is fixed to the upper wall 81 by a fastener or the like, and the third fixing portion 73 is provided at a position where the front end upper portion 70c of the opposing wall 70 is bent toward the inside of the vehicle.

[0013] In the structure of the instrument panel 1 of this embodiment, the lower wall 5 has a first wall portion 51, a second wall portion 52 extending from an upper end portion 51a of the first wall portion 51 toward the front of the vehicle, and a third wall portion 53 extending from a front end portion 52a of the second wall portion 52 toward the upper side of the vehicle. Moreover, the first fixing portion 71 is fixed to the third wall portion 53 using a fastener or the like. Therefore, the lower wall 5 has the first wall portion 51, the second wall portion 52, and the third wall portion 53, and is configured to improve the mounting rigidity of the first fixing portion 71 and the torsional rigidity of the insertion hole 50.

[0014] In the bracket 7 of this embodiment, the first fixing portion 71 and the second fixing portion 72 are disposed with a distance S therebetween in the vehicle front-rear direction, as shown in Fig. 3. This makes it possible to ensure a stroke distance for the bracket 7 to deform when a load is input to the instrument panel 1 toward the front of the vehicle, and the input load is absorbed around the bracket 7. 3, the first fixing portion 71 and the member fixing portion 84 are disposed with a distance L therebetween in the vehicle front-rear direction. This makes it possible to ensure a stroke distance for the bracket 7 to deform when a load is input to the instrument panel 1 toward the front of the vehicle, thereby facilitating the effect of absorbing the input load around the bracket 7.

[0015] Furthermore, in the structure of the instrument panel 1 of this embodiment, the first fixing portion 71 of the bracket 7 and the member fixing portion 84 on the left wall 82 and the right wall 83 of the inner opening 8 are arranged to be aligned in the vehicle width direction in a front view of the vehicle as shown in Figs. 2 to 4. That is, the first fixing portion 71 is arranged side by side in a state where it is located rearward of the vehicle from the member fixing portion 84 and located inside the vehicle from the member fixing portion 84. This improves the rigidity of the insertion hole 50 against deformation in the vehicle width direction when a load is input to the instrument panel 1, and enhances the protective effect of the harness 6. In addition, the rigidity of the inner opening 8 against deformation in the vehicle width direction when a load is input to the instrument panel 1 is also improved, and the gap at the edge between the audio equipment 3 and the instrument panel 1 is stably maintained.

[0016] 2 and 3, an inner end portion 52b is provided on the inner side of the second wall portion 52 in the vehicle width direction, the inner end portion 52b extending upward of the vehicle and forming a part of the wall portion 50a surrounding the harness 6. Furthermore, the wall portion 50a and the third wall portion 53 of the lower wall 5 are connected to each other, and the wall portion 50a has a shape in which the wall portion 50a is continuous with the first wall portion 53, the second wall portion 52 and the third wall portion 53. This improves the torsional rigidity of the insertion hole 50, resulting in a structure that further enhances the protective effect of the harness 6.

[0017] Thus, in the structure of the instrument panel 1 according to the embodiment of the present invention, the instrument panel 1 is attached to the vehicle body via the steering support member 2, and has an opening 4 for mounting the audio equipment 3 and the vehicle operation switches (not shown). The opening 4 has a lower wall 5 extending from the lower edge 4a of the opening toward the front of the vehicle, and the lower wall 5 is provided with a first wall portion 51 extending from a front end portion 5a of the lower wall 5 toward the upper side of the vehicle. The first wall portion 51 is provided with an insertion hole 50 through which the harness 6 of the vehicle operation switch is inserted, and the insertion hole 50 extends in the insertion direction of the harness 6 and is formed by a wall portion 50a surrounding the harness 6. Therefore, in the structure of the instrument panel 1 of this embodiment, the torsional rigidity of the mounting opening 4 for the audio equipment 3, etc. is improved by the bottom wall 5, etc., so that the opening 4 is less likely to twist when mounting the audio equipment 3, thereby improving the ease of mounting the audio equipment 3. In addition, in the structure of the instrument panel 1 of this embodiment, the insertion hole 50 through which the harness 6 of the vehicle operation switch is inserted is formed by the wall portion 50a surrounding the harness 6, so that the harness 6 does not come into contact with and rub against other peripheral components, preventing deterioration of the harness 6 and improving the durability of the vehicle operation switch. Furthermore, in the structure of the instrument panel of this embodiment, the wall portion 50a of the insertion hole 50 increases the rigidity in the harness insertion direction, so that the harness 6 can be effectively protected from an impact load when an impact load is input.

[0018] In the structure of the instrument panel 1 of this embodiment, an inner opening 8 for mounting the audio equipment 3 via a bracket 7 is provided inside the opening 4. The bracket 7 has a first fixing portion 71 and a second fixing portion 72 that are spaced apart in the vehicle width direction and are fixed to the lower wall 5. Meanwhile, the inner opening 8 is formed by an upper wall 81 and a lower wall 5 that are positioned above and below in the vehicle vertical direction, and a left side wall 82 and a right side wall 83 that are positioned to the left and right in the vehicle width direction. A member fixing portion 84 that is fixed to the steering support member 2 is provided at front end portions 82a, 83a of the left side wall 82 and the right side wall 83, and the member fixing portion 84 is located between the first fixing portion 71 and the second fixing portion 72 in a front view of the vehicle. That is, in the structure of the instrument panel 1 of this embodiment, the bracket 7 is provided inside the inner opening 8, which increases the torsional rigidity of the inner opening 8. Therefore, the structure of the instrument panel 1 of this embodiment makes it possible to make the inner opening 8 less likely to deform when the audio system 3 is attached to the inner opening 8, and the gap between the audio system 3 and the instrument panel 1 can be stably maintained, thereby improving the appearance quality of the instrument panel 1.

[0019] Furthermore, in the structure of the instrument panel 1 of this embodiment, the lower wall 5 has a first wall portion 51, a second wall portion 52 extending from an upper end portion 51a of the first wall portion 51 toward the front of the vehicle, and a third wall portion 53 extending from a front end portion 52a of the second wall portion 52 toward the upper side of the vehicle. Moreover, the first fixing portion 71 is fixed to the third wall portion 53. Therefore, in the structure of the instrument panel 1 of this embodiment, the first wall portion 51, the second wall portion 52, and the third wall portion 53 of the lower wall 5 improve the mounting rigidity of the first fixing portion 71, so that the gap at the edge between the audio equipment 3 and the instrument panel 1 is stabilized, and the appearance quality of the instrument panel 1 can be improved. In addition, the structure of the instrument panel 1 of this embodiment improves the torsional rigidity of the insertion hole 50, thereby further enhancing protection of the harness 6 and making the insertion hole 50 less likely to deform during installation of a vehicle operation switch having the harness 6, thereby improving installation workability.

[0020] In the structure of the instrument panel 1 of this embodiment, an inner end portion 52b is provided on the inside of the second wall portion 52 in the vehicle width direction, which extends upward of the vehicle and forms part of the wall portion 50a, and the wall portion 50a and the third wall portion 53 are connected to each other, so that it is possible to improve the torsional rigidity of the insertion hole 50 and further enhance the protective effect of the harness 6.

[0021] Furthermore, in the structure of the instrument panel 1 of this embodiment, the first fixing portion 71 and the second fixing portion 72 are arranged at a distance from each other in the fore-and-aft direction of the vehicle. Therefore, when a load toward the front of the vehicle is input to the instrument panel 1, the stroke distance for which the bracket 7 deforms can be secured, and the input load can be effectively absorbed as the bracket 7 deforms.

[0022] Furthermore, in the structure of the instrument panel 1 of this embodiment, the first fixing portion 71 and the member fixing portion 84 are arranged side by side in the vehicle width direction when viewed from the front of the vehicle, so that when a load is input to the instrument panel 1, the rigidity of the insertion hole 50 against deformation in the vehicle width direction can be improved, and the protective effect of the harness 6 can be further enhanced. In addition, according to the structure of the instrument panel 1 of this embodiment, when a load is input to the instrument panel 1, the rigidity of the inner opening 8 against deformation in the vehicle width direction is also improved, so that the gap at the edge between the audio equipment 3 and the instrument panel 1 can be stabilized, and the appearance quality can be improved.
