Description

[Technical field]

[0001] The present invention relates to an arrangement structure within a motor room. [Background technology]

[0002] Patent Document 1 discloses a mounting structure for a power control device that can prevent the power control device from interfering with other mounted devices and prevent damage to the power control device, even in the event of a vehicle collision, etc.

[0003] Specifically, it is disclosed that even if a collision occurs between the vehicle and an obstacle (collision barrier 30), the impact on the power cable 17 extending from the PCU case 13 is suppressed by ensuring a space for accommodating the power cable 17 (paragraph

[0004] ~

[0005] reference). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2012-144227 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the above-mentioned conventional technology had a problem in that if an impact occurs such that the above-mentioned storage space cannot be secured (for example, if the dash cross member 26 is deformed toward the rear of the vehicle), the power cable 17 may be pinched between the dash panel 22 and the PCU case 13, and may be damaged.

[0006] Therefore, the present invention has been made in consideration of the above-mentioned problems, and aims to provide an arrangement structure within a motor room that can prevent the harness from being pinched between the frame and surrounding components even if the frame moves due to a vehicle collision. [Means for solving the problem]

[0007] The layout structure within a motor room in one embodiment includes a frame structure for mounting electrical equipment in a motor room of a vehicle, a harness connected to the electrical equipment, and a partition separating the motor room from the vehicle interior, wherein the frame structure has a first frame facing the partition, and the harness is arranged on the first frame so as to follow the first frame.

[0009] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. In the following description of the drawings, the same or similar parts are given the same or similar reference numerals. However, it should be noted that the drawings are schematic and the ratios of the dimensions are different from the actual ones. Therefore, the specific dimensions should be determined with reference to the following description. In addition, the drawings may include parts with different dimensional relationships and ratios. In this specification and the drawings, elements having substantially the same functions and configurations are given the same reference numerals to avoid repeated explanations, and elements not directly related to the present invention are not illustrated.

[0010] Hereinafter, the layout structure within a motor room 1 according to one embodiment of the present invention will be described with reference to Figs.

[0011] 1 and 2, the layout structure in a motor room 1 according to this embodiment includes a frame structure 10, a harness 20, a bulkhead 30, an auxiliary battery 3, an inverter 4, and electric equipment 5. The inverter 4 is placed above the electric equipment 5.

[0012] 1 to 3, the harness 20 is configured to be connected to the auxiliary battery 3, the inverter 4, and the electric device 5. FIG. 3 is a diagram in which the inverter 4 is removed from FIG. 2. The harness 20 is configured to perform a role of exchanging signals among the auxiliary battery 3, the inverter 4, and the electric device 5, and of supplying power to the auxiliary battery 3, the inverter 4, and the electric device 5.

[0013] As shown in FIG. 1, the partition wall 30 is configured to separate the motor room 1 and the vehicle interior 2.

[0014] The auxiliary battery 3 is configured to serve as a power source for the inverter 4 and the control device in the electric device 5 .

[0015] The inverter 4 is configured to play a role of converting direct current into alternating current, and also to play a role of adjusting the frequency to drive a motor (not shown) in accordance with the vehicle speed.

[0016] The electrical equipment (charger / converter) 5 is configured to convert AC current supplied from outside the vehicle into DC current to charge the driving battery, and also to reduce the high voltage of the driving battery to charge the auxiliary battery 3.

[0017] The frame structure 10 is configured so that an electric device 5 can be mounted in a motor room 1 of a vehicle. As shown in Figs. 1 to 3, the frame structure 10 has a first frame 12. Here, the first frame 12 is disposed so as to face a partition wall 30, as shown in Fig. 1.

[0018] 2, the harness 20 is disposed on the first frame 12 so as to extend along the first frame 12. Specifically, the harness 20 is attached onto the first frame 12 by a harness attachment portion 20A shown in FIG.

[0019] With this configuration, the harness 20 is attached to the first frame 12, so that even if the vehicle is hit from the outside, the harness 20 is prevented from being pinched between the frame structure 10 and the partition wall 30, thereby preventing damage to the harness 20.

[0020] As shown in FIGS. 1 to 4, the frame structure 10 may further include a main frame 11 that is disposed forward of the first frame 12. As shown in FIG.

[0021] Here, as shown in Figures 1, 3 and 4, the main frame 11 is composed of a pair of first members 11A extending along the partition wall 30 and the horizontal portion 12A (described later), and a pair of second members 11B extending to connect the first members 11A.

[0022] As shown in FIG. 3, the first frame 12 may have a horizontal portion 12A and an extending portion 12B.

[0023] As shown in FIGS. 1 and 3, the horizontal portion 12A is disposed so as to extend along the partition wall 30. As shown in FIG.

[0024] As shown in FIG. 3, the extension portion 12B is disposed so as to extend from the main frame 11 to the horizontal portion 12A.

[0025] With this configuration, when the vehicle is hit from the outside and the frame structure 10 comes into contact with the partition 30, the first frame 12 comes into contact with the partition 30 via the horizontal portion 12A, thereby preventing the first frame 12 from hitting the partition 30 locally, thereby suppressing intrusion of the frame structure 10 into the vehicle interior 2 and also suppressing deformation of the first frame 12 and the partition 30.

[0026] Furthermore, with this configuration, the harness 20 is disposed at a position far from the exterior of the vehicle, so that it is possible to prevent the harness 20 from being damaged due to collision with other components during a collision.

[0027] As shown in FIG. 3, a front end 12E of the extension 12B faces the front side of the vehicle and is disposed so as to be perpendicular to the main frame 11 extending in the vehicle width direction.

[0028] With this configuration, when the vehicle is hit from the outside and the first frame 12 collides with the partition wall 30, the front end 12E of the extension portion 12B is perpendicular to the main frame 11 in the fore-and-aft direction of the vehicle, thereby suppressing local deformation of the front end 12E of the first frame 12.

[0029] Here, when the front end 12E of the extension portion 12B is connected diagonally to the main frame 11 in the fore-and-aft direction of the vehicle, there is a risk that the front end 12E of the extension portion 12B of the first frame 12 will be locally deformed due to contact with the partition wall 30; however, with the above-described configuration, such a risk can be reduced.

[0030] Moreover, the electric device 5 to which the harness 20 is connected is configured to be mounted on the frame structure 10 as shown in FIGS.

[0031] Generally, when an external impact is applied to a vehicle, the external impact is applied to the electric device 5 attached to the frame structure 10, and there is a risk that the electric device 5 will move rearward. According to the above-described configuration, even if the electric device 5 comes into contact with the harness 20 in such a case, the harness 20 is pushed by the electric device 5 and can move between the first frame 12 and the partition wall 30 because there is a gap between the harness 20 and the partition wall 30, and damage to the harness 20 can be suppressed.

[0032] Furthermore, as shown in Fig. 4, the harness 20 is disposed so as to extend laterally (i.e., in the vehicle width direction) from a side portion of the electric device 5 and then extend rearward (i.e., in the vehicle front-rear direction). Specifically, as shown in Fig. 4, the harness 20 is configured so as to extend rightward from a right side portion of the electric device 5 and then extend rearward.

[0033] According to this configuration, since the connection point of the harness 20 to the electrical equipment 5 does not face the partition wall 30, if the electrical equipment 5 is displaced toward the partition wall 30 together with the harness 20 due to an external impact, the harness 20 extending from the electrical equipment 5 toward the partition wall 30 deforms so as to bulge sideways, thereby suppressing damage to the harness 20.

[0034] Here, if the connection points of the harness 20 to the electric device 5 are on the surface of the electric device 5 facing the bulkhead 30 (i.e., the surface of the electric device 5 facing the rear of the vehicle), the harness 20 is likely to be damaged. The reason is that the harness 20 extends from the surface of the electric device 5 toward the bulkhead, and the connection points of the harness 20 to the electric device 5 also face the bulkhead 30. In such a case, if the electric device 5 is pushed toward the inside of the vehicle by an external impact, the connection points of the harness 20 to the electric device 5 will receive a force that bends them sideways or up and down, and there is a risk that such connection points will be damaged.

[0035] As shown in FIG. 3, a front end 12E of the first frame 12 is butted against and connected to the main frame 11.

[0036] With this configuration, if the frame structure 10 is pushed back by an external collision and the partition 30 collides with the first frame 12, the impact received by the first frame 12 can also be received by the main frame 11, thereby suppressing deformation of the first frame 12 and suppressing damage to the harness 20.

[0037] Although the present invention has been described in detail using the above-mentioned embodiment, it is clear to those skilled in the art that the present invention is not limited to the embodiment described in the present specification. The present invention can be implemented in modified and altered forms without departing from the spirit and scope of the present invention defined by the description of the claims. Therefore, the description in this specification is intended to be illustrative and does not have any limiting meaning on the present invention. [Industrial Applicability]

[0038] According to this embodiment, it is possible to provide an arrangement structure within the motor room 1 that can prevent the harness 20 from being pinched between the frame and surrounding members even if the frame moves due to a vehicle collision. [Explanation of symbols]
