Description

[Technical Field]

[0001] The present invention relates to a dash panel. [Background technology]

[0002] The following Patent Document 1 discloses a configuration in which an immobilizer ECU (Electronic Control Unit) is attached to a dash panel inside the vehicle cabin. The dash panel described in this document has stud bolts fixed thereto. The stud bolts are located in the path of the immobilizer ECU, which prevents the immobilizer ECU from being accidentally removed, thereby preventing vehicle theft.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-202753 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in a configuration in which the ECU is disposed on the interior side of the vehicle cabin relative to the dash panel, as in the configuration described in Patent Document 1, it is conceivable that the ECU will hinder expansion of the space inside the vehicle cabin.

[0005] SUMMARY OF THE INVENTION In consideration of the above, an object of the present invention is to provide a dash panel that can suppress obstruction to expansion of the space inside the vehicle cabin. [Means for solving the problem]

[0006] The dash panel of the first aspect comprises a dash panel main body that separates the interior and exterior of the vehicle, an ECU case portion formed integrally with the dash panel main body, and a circuit portion provided within the ECU case portion.

[0007] In the dash panel of the first aspect, the ECU case housing the circuit is integrally formed with the dash panel body, which reduces the obstruction to the expansion of the vehicle interior space compared to a configuration in which the ECU containing the circuit and ECU case is attached to the interior side of the dash panel body. [Effects of the Invention]

[0008] The dash panel according to the present invention has the excellent effect of suppressing obstruction to the expansion of the space inside the vehicle compartment. [Brief explanation of the drawings]

[0009] [Figure 1] FIG. 2 is a perspective view of the dash panel as seen from inside the vehicle interior. [Figure 2] 2 is a cross-sectional view showing a cross section of the dash panel taken along line 2-2 shown in FIG. 1. DETAILED DESCRIPTION OF THE INVENTION

[0010] A dash panel 10 according to an embodiment of the present invention will now be described with reference to the drawings. Note that the arrow FR shown in each drawing indicates the front side of the vehicle, the arrow UP indicates the upper side of the vehicle, the arrow LH indicates the left side in the vehicle width direction (left-right direction), and the arrow RH indicates the right side in the vehicle width direction (left-right direction). Furthermore, unless otherwise specified, when referring to front-rear, up-down, and left-right directions in the following description, these refer to front-rear in the front-rear direction of the vehicle, up-down in the vehicle up-down direction, and left-right in the vehicle left-right direction.

[0011] 1 and 2, dash panel 10 is made of a resin material. Dash panel 10 includes dash panel main body 16 that separates vehicle interior 12 from vehicle exterior 14, ECU case 18 formed integrally with dash panel main body 16, and circuit section 20 provided within ECU case 18.

[0012] The dash panel body 16 is formed in a plate shape that extends in the left-right and up-down directions with the thickness direction being in the front-rear direction.

[0013] The ECU case 18 is formed so as to protrude rearward (toward the vehicle interior 12) from the vertically intermediate portion of the right side of the dash panel main body 16. As an example, the ECU case 18 is formed in the shape of a rectangular block corresponding to the shape of the circuit section 20 described below. A plurality of heat dissipation fins 22 are formed at the rear end of the ECU case 18, and these plurality of heat dissipation fins 22 are arranged at intervals in the vertical direction.

[0014] The circuit section 20 is configured to include a circuit board and circuit elements attached to the circuit board. The majority of the circuit section 20 is embedded in the ECU case section 18 and is fixed to the ECU case section 18. When the circuit section 20 is fixed to the ECU case section 18, a portion 20A of the circuit section 20 is located inside the dash panel main body 16.

[0015] (Actions and Effects of This Embodiment) Next, the operation and effects of this embodiment will be described.

[0016] In the dash panel 10 of the present embodiment described above, the ECU case 18 in which the circuit unit 20 is provided is formed integrally with the dash panel main body 16. This configuration prevents the ECU (circuit unit 20 and ECU case 18) from interfering with the expansion of the space inside the vehicle interior 12, compared to a configuration in which the ECU having the circuit unit 20 and ECU case 18 is attached to the interior side of the dash panel main body 16. Furthermore, the configuration of the present embodiment allows for a more attractive design of the vehicle interior 12, compared to a configuration in which the ECU having the circuit unit 20 and ECU case 18 is attached to the interior side of the vehicle interior.

[0017] Furthermore, in this embodiment, a portion 20A of the circuit unit 20 is located inside the dash panel main body 16. In this configuration, the size of the ECU case unit 18 can be prevented from increasing, compared to a configuration in which the entire circuit unit 20 is located inside the ECU case unit 18. This further prevents the ECU (circuit unit 20 and ECU case unit 18) from interfering with the expansion of the space inside the vehicle interior 12.

[0018] In this embodiment, a plurality of heat dissipation fins 22 are formed at the rear end of the ECU case 18. This allows heat from the circuit unit 20 to be dissipated to the vehicle interior 12 via the plurality of heat dissipation fins 22. Note that the plurality of heat dissipation fins 22 may be formed to protrude to the vehicle exterior 14, allowing heat from the circuit unit 20 to be dissipated to the vehicle exterior 14.

[0019] In this embodiment, the dash panel 10 is formed using a resin material. In this configuration, by using a resin material containing carbon fiber at least in the portion corresponding to the ECU case portion 18, it is possible to reduce electromagnetic waves emitted from the circuit portion 20.

[0020] In this embodiment, an example in which multiple heat dissipation fins 22 are provided has been described, but the present invention is not limited to this. Whether or not multiple heat dissipation fins 22 are provided can be determined appropriately taking into consideration the amount of heat dissipation from the circuit unit 20, etc.

[0021] In addition, in this embodiment, an example has been described in which part 20A of circuit unit 20 is located inside dash panel main body 16, but the present invention is not limited to this. For example, depending on the size of circuit unit 20, a configuration in which the entire circuit unit 20 is located inside ECU case 18 may also be adopted.

[0022] The above describes one embodiment of the present invention, but the present invention is not limited to the above, and it goes without saying that it can be implemented in various other modified forms within the scope of the gist of the present invention. [Explanation of symbols]
