[0005] Patent Document 1: Japanese Patent Application Publication No. 2019-55615 Summary of the Invention

[0006] Technical problem to be solved by the invention

[0007] As described in patent document 1, in a structure in which a vehicle-mounted device is arranged and fixed at a specified position on a base face portion fixed on an instrument panel and intersecting the front-rear direction of the vehicle (for example, the rear surface portion of the instrument panel or the center component panel, etc.), a bent face portion is provided, and the bent face portion has: a rear bent portion bent from the base face portion toward the front of the vehicle; an intermediate face portion extending from the rear bent portion toward the front of the vehicle; a front bent portion bent from the front end of the intermediate face portion toward the side of the counter-base face portion that is not opposite to the base face portion; and a bottom face portion extending from the front bent portion toward the side of the counter-base face portion, the bent face portion defining a concave space that is recessed from the base face portion toward the front of the vehicle, and sometimes a vehicle-mounted device is arranged and fixed in the concave space.

[0008] However, in a structure in which the above-mentioned curved surface is provided on the instrument panel, the curved surface (particularly the rear curved surface) increases the surface rigidity of the base surface. Therefore, when a passenger collides with the front instrument panel (the base surface or the curved surface) during a vehicle collision, it is preferable to mitigate the impact received by the passenger from the instrument panel side.

[0009] Therefore, an object of the disclosure is to provide an instrument panel structure that can mitigate the impact received by a passenger from the instrument panel side during a vehicle collision.

[0010] Technical means for solving technical problems

[0011] To achieve the above object, a first aspect of the present disclosure is an instrument panel structure in which a base surface intersecting the vehicle longitudinal direction is fixed to an instrument panel at the front of a vehicle cabin, and the base surface comprises a bent surface, a bottom slit, and a middle slit.

[0012] The bent surface portion includes a rear bent portion, an intermediate portion, a front bent portion, and a bottom portion, defining a concave space recessed from the base surface portion toward the front of the vehicle. The rear bent portion bends from the base surface portion toward the front of the vehicle, the intermediate portion extends from the rear bent portion toward the front of the vehicle, the front bent portion bends from the front end of the intermediate portion toward the opposite base surface portion, not facing the base surface portion, and the bottom portion extends from the front bent portion toward the opposite base surface portion. The bottom slit is a slit-shaped hole formed in the bottom surface portion so as to extend along the front bent portion. The intermediate slit is a slit-shaped hole formed in the bent surface portion so as to extend from the bottom slit across the front bent portion toward the intermediate portion.

[0013] In the above configuration, if a passenger collides with the front instrument panel (the base surface or the curved surface) during a vehicle collision, and a forward load is applied to the curved surface, the bottom slit and the middle slit widen and open three-dimensionally. This allows the base surface to move significantly forward, mitigating the impact on the passenger from the instrument panel.

[0014] The second embodiment of the present disclosure is an instrument panel structure of the first embodiment in which an assembly panel having a base surface is fixed to the instrument panel, wherein a panel mounting portion fixed to the instrument panel is provided on the bottom surface, and the bottom slit extends across between the panel mounting portion and the front bent portion.

[0015] In the above configuration, the bottom slit extends across the panel mounting portion and the front bent portion, so when a forward load is input to the bent portion, the bottom slit easily widens, thereby further mitigating the impact on the passenger from the instrument panel side.

[0016] A third aspect of the present disclosure is an instrument panel structure in which an assembly panel is fixed to an instrument panel at the front of a vehicle cabin, the assembly panel having a base surface intersecting the vehicle front-rear direction, and having a bent surface and a bottom slit.

[0017] The bent surface portion includes a rear bent portion, an intermediate portion, a front bent portion, and a bottom portion, defining a concave space recessed from the base surface portion toward the front of the vehicle. The rear bent portion bends from the base surface portion toward the front of the vehicle, the intermediate portion extends toward the front of the vehicle from the rear bent portion, the front bent portion bends from the front end of the intermediate portion toward the opposite side of the base surface portion, and the bottom portion extends from the front bent portion toward the opposite side of the base surface portion. A bottom slit is formed in the bottom surface portion in the shape of a slit extending along the front bent portion. A panel mounting portion for mounting to the instrument panel is provided on the bottom surface portion, and the bottom slit extends transversely between the front bent portion and the panel mounting portion.

[0018] In this configuration, if a passenger collides with the front instrument panel (the base surface or the curved surface) during a vehicle collision, and a forward load is applied to the curved surface, the bottom slit widens and opens. Furthermore, because the bottom slit extends across the panel mounting portion and the front curved portion, it easily widens when a forward load is applied to the curved surface. This allows the base surface to move significantly forward, mitigating impacts on the passenger from the instrument panel.

[0019] A fourth aspect of the present disclosure is the instrument panel structure of the second or third aspect, wherein the bottom portion is a frame defining a rectangular bottom opening, and the bottom slit is formed in the bottom portion within an opening width of the bottom opening and does not extend outside the opening width.

[0020] In the above configuration, since the bottom slit does not extend outside the opening width of the bottom opening, it is possible to suppress a reduction in the rigidity of the assembly panel due to the bottom slit and mitigate the impact received by the passenger from the instrument panel side.

[0021] A fifth aspect of the present disclosure is the instrument panel structure of the fourth aspect, wherein the distance from the bottom slit to the front bent portion is shorter than the distance from the bottom slit to the opening edge of the bottom opening.

[0022] In the above configuration, since the distance from the bottom slit to the front bent portion is shorter than the distance to the opening edge of the bottom opening, the bottom slit is positioned closer to the front bent portion than the opening edge (offset toward the front bent portion). Therefore, compared to a case where the bottom slit is positioned off-set toward the opening edge, the bottom slit is more likely to widen when a forward load is applied to the base surface. Consequently, the impact on the passenger from the instrument panel side can be further mitigated.

[0023] Effects of the Invention

[0024] According to the present disclosure, it is possible to mitigate the impact received by a passenger from the instrument panel side during a vehicle collision. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] An embodiment of the present disclosure is described below based on the accompanying drawings. In each of the drawings, FR represents the front of the vehicle, and UP represents the top. In the following description, the front-back direction refers to the front-back direction of the vehicle, and the left-right direction refers to the left-right direction when facing the front of the vehicle.

[0032] The instrument panel 1 is a resin panel that is arranged in front of the vehicle compartment 2 and is fixed to the vehicle body side and extends in the vehicle width direction. Figure 1 As shown, the vehicle comprises an instrument panel upper surface portion 3 intersecting the vertical direction, and an instrument panel rear surface portion 4 extending downward from the rear end edge of the instrument panel upper surface portion 3. A central instrument panel opening (not shown) is formed at the upper portion of the center of the instrument panel rear surface portion 4 in the vehicle width direction, for accommodating onboard equipment 5 (see FIG. 4 ), such as an audio system. A bezel (center unit bezel) 6 is attached to the instrument panel rear surface portion 4 to cover the area including the instrument panel central opening from behind.

[0033] The frame 6 is a decorative panel made of resin and mounted on the rear surface portion 4 of the instrument panel from the rear. Figures 2 to 5 As shown, the integral body has a base surface 10 that intersects the front-to-back direction and a curved surface 12 that is recessed forward from the base surface 10 to define a rectangular concave space 11. The base surface 10 is fixed to the instrument panel 1, and the frame 6 having the base surface 10 constitutes an assembly panel. In addition, the so-called integral body includes, in addition to integral molding, the case where separately molded parts are fixed to form an integral body. In addition, in the following description, regarding the direction of the frame 6, unless otherwise specified, it refers to the direction in the frame installation state where the frame 6 is installed on the rear surface portion 4 of the instrument panel.

[0034] The bent surface portion 12 is a stepped shape that is recessed forward from the base surface portion 10, and comprises: a rear bent portion 13 bent forward from the base surface portion 10; an intermediate surface portion 14 extending forward from the rear bent portion 13; a front bent portion 15 bent from the front end of the intermediate surface portion 14 toward the anti-base surface portion side that is not opposite to the base surface portion 10; and a bottom surface portion 16 extending from the front bent portion 15 toward the anti-base surface portion side.

[0035] The bottom portion 16 is a frame-shaped structure defining a rectangular bottom opening 17. A plurality of bolt insertion holes 19 are formed in the bottom portion 16. The vehicle-mounted device 5 is fastened to the frame 6 by bolts (not shown) inserted through the bolt insertion holes 19. The bottom opening 17 exposes the front surface of the vehicle-mounted device 5 fixed to the frame 6 to the front.

[0036] A plurality of clips (panel mounting portions) 20 are protruding from the front surface of the bottom portion 16 (in this embodiment, three above and two below the bottom opening 17). The bottom portion 16 is mounted to the instrument panel rear portion 4 by inserting and locking the clips 20 from the rear into the rectangular clip locking holes 18 formed on the instrument panel rear portion 4. In addition, a plurality of other ( Figure 3 A portion of which is shown in FIG. 2 ) a clip 21.

[0037] The bent surface portion 12 is formed with a single bottom slit 22 and two intermediate slits 27 separated into left and right sides. The bottom slit 22 and intermediate slits 27 are slit-shaped holes extending through the bent surface portion 12. The bottom slit 22 and intermediate slits 27 communicate with each other, and by widening the bottom slit 22 and intermediate slit 27, they become integrated and open three-dimensionally. The number of bottom slits 22 and intermediate slits 27 is not limited to the number described above and can be arbitrarily set.

[0038] The bottom slit 22 extends linearly in the vehicle width direction along the front bent portion 15 in the bottom surface portion 16 below the bottom opening 17, crossing between the clip 20 and the front bent portion 15. The middle slit 27 extends linearly from the bottom slit 22 across the front bent portion 15 to the rear of the rear bent portion 13 on the middle surface portion 14.

[0039] The bottom slit 22 is formed in the inner region 23 of the opening width D of the bottom opening 17 of the bottom surface portion 16 and does not extend to the outside of the opening width D. The inner region 23 of the opening width D of the bottom opening 17 is the region between the left and right boundary lines 25 extending downward from the left and right opening edges 24 of the bottom opening 17. The bottom slit 22 does not extend to the left or right beyond the left and right boundary lines 25 (see Figure 3 In addition, the bottom slit 22 is biased toward the front bent portion 15 , and a distance L1 from the bottom slit 22 to the front bent portion 15 is shorter than a distance L2 from the bottom slit 22 to the opening edge 26 below the bottom opening 17 .

[0040] According to this embodiment, when a passenger collides with the front side of the instrument panel 1 (the base surface 10 or the bent surface 12) during a vehicle collision, a forward load is applied to the bent surface 12, causing the bottom slit 22 and the middle slit 27 to widen and open three-dimensionally. This allows the base surface 10 to move forward significantly, mitigating the impact on the passenger from the instrument panel 1 side.

[0041] Since the bottom slit 22 extends across between the clip 20 and the front bent portion 15 , it easily widens when a forward load is input to the bent surface portion 12 . This further reduces the impact on the passenger from the instrument panel 1 side.

[0042] Since the bottom slit 22 does not extend outside the opening width D of the bottom opening 17 , a reduction in the rigidity of the bezel 6 due to the bottom slit 22 can be suppressed, and the impact received by the passenger from the instrument panel 1 side can be mitigated.

[0043] Furthermore, because the distance L1 from the bottom slit 22 to the front bent portion 15 is shorter than the distance L2 to the opening edge 26 of the bottom opening 17, the bottom slit 22 is positioned closer to the front bent portion 15 than the opening edge 26 (offset toward the front bent portion 15). Therefore, compared to a case where the bottom slit 22 is positioned off-set toward the opening edge 26, the bottom slit 22 is more likely to widen when a forward load is applied to the base surface portion 10. Consequently, the impact received by the passenger from the instrument panel 1 side can be further mitigated.

[0044] While the present disclosure has been described above based on the aforementioned embodiments, the present disclosure is not limited to the contents of the aforementioned embodiments and can be appropriately modified without departing from the scope of the present invention. Specifically, other embodiments, examples, and application techniques accomplished by those skilled in the art based on the present embodiments are naturally all encompassed within the scope of the present invention.

[0045] For example, in the above embodiment, the bezel 6 is fixed to the instrument panel 1 and the base surface portion 10 and the bent surface portion 12 are formed on the bezel 6 . However, the base surface portion 10 and the bent surface portion 12 may be formed on the instrument panel 1 .

[0046] In addition, the above embodiment describes an example in which the bottom opening 17 is formed in the bottom portion 16 and the bottom slit 22 is formed in the bottom portion 16 below the bottom opening 17, but the bottom slit 22 may be formed in the bottom portion 16 other than below the bottom opening 17, or the bottom slit 22 may be formed in the bottom portion 16 without forming the bottom opening 17.

[0047] This application is based on Japanese patent application (Japanese Patent Application No. 2020-059475) filed on March 30, 2020, the contents of which are incorporated herein by reference.
