[0006] The problem to be solved by the utility model

[0007] For example, when a car charger is fixed to a vehicle, there is a possibility that the noise generated by the charger may affect surrounding equipment. Furthermore, such car chargers have connectors attached, and in the event of a vehicle collision, there is a possibility that not only the car charger but also the connectors could be damaged.

[0008] Therefore, the purpose of this utility model is to provide a vehicle charger protection device that can secure the spare tire, suppress the emission of noise generated by the vehicle charger, and prevent damage to the vehicle charger and connectors during a vehicle collision.

[0009] Solution for solving the problem

[0010] The above objective is achieved by the following vehicle charger protection device, which includes: a metal protective cover that covers the upper part of the vehicle charger and the connector connected to the vehicle charger, shielding the noise from the vehicle charger; and a fastening member for fastening the spare tire to the upper part of the protective cover.

[0011] Effects of the utility model

[0012] According to this utility model, a vehicle charger protection device can be provided, which can secure the spare tire, suppress the emission of noise generated by the vehicle charger, and prevent damage to the vehicle charger and connectors during a vehicle collision. Attached Figure Description

[0013] Figure 1 This is a 3D diagram of the onboard charger protection device. Detailed Implementation

[0014] Figure 1This is a perspective view of the vehicle charger protection device 1. The vehicle charger protection device 1 includes a protective cover 10 and a fastening member 20. The protective cover 10 protects the vehicle charger 100. The vehicle charger 100 is housed in a recess formed in the rear floor 200 of the vehicle. Additionally, in... Figure 1 Only a portion of the rear floor 200 is shown in the image. Figure 1 The diagram shows the X-axis, Y-axis, and Z-axis directions as orthogonal coordinates. The Y-axis represents the rear of the vehicle. The X-axis represents the side of the vehicle. The Z-axis represents the height direction.

[0015] The vehicle charger 100 is secured to the rear floor 200 by multiple brackets 140. The vehicle charger 100, for example, charges the vehicle's main battery. Additionally, the vehicle charger 100 has a power supply function, for example, it can supply power to the vehicle's auxiliary battery from the main battery. A protective cover 10 is secured to the rear floor 200 to cover the upper part of the vehicle charger 100.

[0016] The protective cover 10 has an upper wall portion 12, an extended wall portion 14, a side wall portion 16, and a bent portion 18. The upper wall portion 12 is located above the upper surface 102 of the vehicle charger 100 with an open gap. Furthermore, the length of the upper wall portion 12 in the X direction is greater than the length of the upper surface 102 in the X direction. A plurality of connectors 130 are connected to the left side surface 103 of the vehicle charger 100. The length of the upper wall portion 12 in the X direction is greater than the length in the X direction including the upper surface 102 and the plurality of connectors 130 connected to the left side surface 103. Therefore, for example, in the event of a vehicle collision, damage to the connectors 130 or the vehicle charger 100 can be prevented. Thus, leakage current caused by their damage can also be suppressed.

[0017] The extension wall portion 14 extends from the upper wall portion 12 in the -Y direction and is fixed to the rear floor 200 by fastening members (not shown) such as bolts or brackets. The side wall portion 16 bends from the upper wall portion 12 and faces the rear side 106 of the on-board charger 100 with a predetermined gap. The bent portion 18 bends from the side wall portion 16 and is fixed to the rear floor 200 by fastening members (not shown).

[0018] Here, the protective cover 10 is made of metal, specifically formed by bending an iron plate. The vehicle charger 100 has its upper surface 102 and rear side 106 covered by the protective cover 10. The other sides or bottom of the vehicle charger 100 are covered by the rear floor 200. The rear floor 200 is also made of metal. Here, the vehicle charger 100 has multiple switching elements, and therefore, noise is emitted to the outside due to the operation of the switching elements. As described above, since the vehicle charger 100 is covered by the metal protective cover 10 and the rear floor 200, the noise emitted by the vehicle charger 100 can be shielded. Thus, the influence of the noise of the vehicle charger 100 on surrounding equipment can be suppressed.

[0019] A fastening member 20 for mounting a spare tire is installed on the upper part of the upper wall portion 12. The fastening member 20 has a head 22 and a shaft portion 24. The head 22 is in the shape of a circular plate. A threaded hole 13 is provided on the upper wall portion 12, which is threadedly engaged with the shaft portion 24. With the spare tire positioned on the upper wall portion 12, the shaft portion 24 of the fastening member 20 is threadedly engaged with the threaded hole 13, thereby causing the head 22 to abut against the edge of the center hole of the spare tire. In this way, the spare tire can be fastened to the protective cover 10 by the fastening member 20.

[0020] In addition, such as Figure 1 As shown, the vehicle charger 100 is designed with a low profile. Correspondingly, the upper wall 12 of the protective cover 10 is also positioned with a gap opening from the upper surface 102 of the vehicle charger 100. Therefore, the vehicle charger protection device 1 can effectively utilize the space inside the vehicle, protecting the vehicle charger 100 and securing the spare tire.

[0021] The embodiments of the present invention have been described in detail above. The present invention is not limited to the specific embodiments described above. Various modifications and alterations can be made within the scope of the concept of the present invention as set forth in the claims.
