Description

[Technical Field]

[0001] The present invention relates to an on-board charger protection device. [Background technology]

[0002] There is a structure in which an on-board battery is fixed to a vehicle by a battery bracket, and a spare tire is fastened to the upper part of the battery bracket by a tire mounting bracket (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2017-132450 A Summary of the Invention [Problem to be solved by the invention]

[0004] For example, when an on-board charger is fixed to a vehicle, noise emitted by the on-board charger may affect peripheral devices. In addition, such on-board chargers are connected to connectors, and in the event of a vehicle collision, not only the on-board charger but also the connector may be damaged.

[0005] Therefore, an object of the present invention is to provide an on-board charger protection device that can fasten a spare tire, suppresses noise radiation from the on-board charger, and prevents damage to the on-board charger and connector in the event of a vehicle collision. [Means for solving the problem]

[0006] The above object can be achieved by an on-board charger protection device that includes a metal shield cover that covers the top of the on-board charger and the connector connected to the on-board charger and blocks noise from the on-board charger, and a fastening member for fastening a spare tire to the top of the shield cover. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide an on-board charger protection device that can fasten a spare tire, suppresses noise radiation from an on-board charger, and prevents damage to the on-board charger and connector in the event of a vehicle collision. [Brief explanation of the drawings]

[0008] [Figure 1] FIG. 2 is a perspective view of the on-board charger protection device. DETAILED DESCRIPTION OF THE INVENTION

[0009] FIG. 1 is a perspective view of an on-board charger protection device 1. The on-board charger protection device 1 includes a shield cover 10 and a fastening member 20. The shield cover 10 protects the on-board charger 100. The on-board charger 100 is stored in a recess formed in a rear floor 200 of the vehicle. Note that FIG. 1 only shows a portion of the rear floor 200. FIG. 1 shows the X-axis direction, Y-axis direction, and Z-axis direction, which are orthogonal coordinates. The Y-axis direction indicates the rear side of the vehicle. The X-axis direction indicates the lateral side of the vehicle. The Z-axis direction indicates the height direction.

[0010] The on-board charger 100 is fixed to the rear floor 200 by multiple brackets 140. The on-board charger 100 charges, for example, the main on-board battery. The on-board charger 100 also has a power supply function, and can supply power from, for example, the main on-board battery to an auxiliary on-board battery. The shield cover 10 is fixed to the rear floor 200 so as to cover the top of the on-board charger 100.

[0011] The shield cover 10 has an upper wall portion 12, an extending wall portion 14, a side wall portion 16, and a bent portion 18. The upper wall portion 12 is located above an upper surface 102 of the in-vehicle charger 100 with a gap therebetween. The length of the upper wall portion 12 in the X direction is longer than the length of the upper surface 102 in the X direction. Multiple connectors 130 are connected to a left side surface 103 of the in-vehicle charger 100. The length of the upper wall portion 12 in the X direction is longer than the length of the upper surface 102 and the multiple connectors 130 connected to the left side surface 103 in the X direction. This prevents damage to the connectors 130 and the in-vehicle charger 100, for example, in the event of a vehicle collision. Therefore, leakage current caused by such damage is also suppressed.

[0012] The extension wall portion 14 extends in the -Y direction from the upper wall portion 12 and is fixed to the rear floor 200 by fastening members (not shown) such as bolts or brackets. The side wall portion 16 is bent from the upper wall portion 12 and faces the rear side surface 106 of the in-vehicle charger 100 with a predetermined gap therebetween. The bent portion 18 is bent from the side wall portion 16 and is fixed to the rear floor 200 by fastening members (not shown).

[0013] Here, the shield cover 10 is made of metal, and specifically, is formed by bending an iron plate. The top surface 102 and rear side surface 106 of the on-board charger 100 are covered by the shield cover 10. The other sides and bottom surface of the on-board charger 100 are covered by the rear floor 200. The rear floor 200 is also made of metal. Here, the on-board charger 100 has multiple switching elements, and noise is emitted to the outside due to the operation of the switching elements. As described above, the on-board charger 100 is covered by the metal shield cover 10 and rear floor 200, so the noise emitted by the on-board charger 100 is blocked. This reduces the impact of noise from the on-board charger 100 on peripheral devices.

[0014] A fastening member 20 for attaching a spare tire is attached to the top of the upper wall portion 12. The fastening member 20 has a head portion 22 and a shaft portion 24. The head portion 22 is disk-shaped. The upper wall portion 12 has a screw hole 13 that screws into the shaft portion 24. With the spare tire placed on the upper wall portion 12, the shaft portion 24 of the fastening member 20 is screwed into the screw hole 13, so that the head portion 22 abuts against the edge of the center hole of the spare tire. In this way, the spare tire can be fastened to the shield cover 10 by the fastening member 20.

[0015] 1, the on-board charger 100 has a low profile. Correspondingly, the upper wall portion 12 of the shield cover 10 is also positioned with a small gap from the upper surface 102 of the on-board charger 100. Therefore, the on-board charger protection device 1 can effectively utilize the space inside the vehicle to protect the on-board charger 100 while fastening the spare tire.

[0016] Although the embodiments of the present invention have been described in detail above, the present invention is not limited to such specific embodiments, and various modifications and variations are possible within the scope of the gist of the present invention as defined in the claims.
