Japanese Unexamined Patent Publication No. 2013-247689

An object of the present invention is to provide a protective structure for mounting various devices on the lower surface side of a vehicle body.

The vehicle-mounted object protection structure according to the present invention is a vehicle-mounted object protection structure mounted on the lower surface side of the vehicle body, and includes a pair of a first protector and a second protector connected to the vehicle body side, and the first protector and the above. The second protector is connected by a connecting panel, and the vehicle-mounted object is mounted on the lower surface side of the connecting panel.

Here, the in-vehicle object means various devices mounted on the lower surface side of the vehicle body.
For example, it refers to a device to be charged on the side that is non-contactly charged by a charging device such as a primary coil installed on the ground side or a resonance circuit thereof.
The device to be charged includes various devices for charging a secondary battery mounted on a vehicle in a non-contact manner, such as a secondary coil, its resonance circuit, a control circuit, and a device for transmitting and receiving a control signal with the charging device.
These various devices are mounted between the first protector and the second protector on the lower surface side of the connecting panel.

In the present invention, the in-vehicle object may be fastened to the first protector and the second protector.
In this way, the connecting portion on the vehicle body side and the in-vehicle object to be protected are connected via the first and second protectors, and the vibration resistance is improved.

In the present invention, the first protector and / or the second protector may have a shock absorbing portion having a hollow cross-sectional shape located on the side portion of the vehicle-mounted object.
In this way, energy is absorbed by the deformation of the shock absorbing portion having a hollow cross-sectional shape, and the in-vehicle object can be protected.

In the present invention, the connecting panel may have a hollow cross-sectional shape.
In this way, the load applied to the vehicle-mounted object from the lower surface side is transmitted to the connecting panel, and the protective effect is improved.
Further, a medium for temperature control can be flowed through the hollow portion of the connecting panel.

In the present invention, it is preferable that the first protector, the second protector and the connecting panel are made of aluminum.
When aluminum, for example, an extruded material or plate material made of aluminum alloy is used in this way, it has the effect of shielding the electric field and shielding the magnetic field against high-frequency current, and can protect other on-board equipment from noise. ..
In addition, aluminum material has excellent heat transfer properties.

In the vehicle-mounted object protection structure according to the present invention, the vehicle-mounted object is located on the lower surface side of the connecting panel connected between the first and second protectors so as to be located between the pair of first protectors and the second protector. Because it is equipped with, it has a high protective effect while the vehicle is running and has excellent vibration resistance.
In particular, if it is made of aluminum, it has excellent thermal conductivity, so it is effective for heat dissipation of in-vehicle objects and also has a high shielding effect for electric and magnetic fields.

(A) shows an example of the protective structure 10 used for the protection structure of the vehicle-mounted object according to the present invention, and (b) shows an example of mounting the vehicle-mounted object 20 on the lower surface side of the vehicle body. An example of fitting and connecting the connecting panel is shown. A second embodiment of the protective structure is shown. A schematic diagram showing an in-vehicle object mounted on the lower surface side of the vehicle body is shown.

An example of a protective structure for an in-vehicle object according to the present invention will be described below with reference to the drawings.
FIG. 1 shows an example of the protective structure 10, and FIG. 4 shows an example in which the protective structure 10 is mounted on the lower surface side of the vehicle body 1.
The mounting position is not particularly limited as long as it is on the lower surface side of the vehicle body depending on the specifications of the vehicle.

In the protective structure 10, the first protector 11 and the second protector 12 are arranged to face each other as a pair, and the first protector 11 and the second protector 12 are connected to each other by connecting panels 13 and 14.
FIG. 1B shows an example in which an in-vehicle object 20 to be protected by using the protective structure 10 is mounted on the lower surface side of the vehicle body.
The upper surface portion 11c of the first protector 11 is connected to the vehicle body member 1a such as one of the skeleton members constituting the vehicle body with bolts or the like (not shown), and the upper surface portion 12c of the second protector 12 is connected to the other vehicle body member of the vehicle body. It is connected to 1a.
The first and second protectors may be arranged so as to face each other in the front-rear direction of the vehicle body 1, or may be arranged so as to face each other in the width direction of the vehicle body 1, and the arrangement direction can be adjusted to the specifications of the vehicle body.

The first and second protectors 11 and 12 are located on the side of the vehicle-mounted object 20, and are panel connecting portions 11b between the shock absorbing portions 11a and 12a having a hollow cross-sectional shape and the connecting panels 13 and 14 having a hollow cross-sectional shape. , 12b and.
The connecting panel may have a single panel structure, but may be divided into a plurality of panel materials in consideration of extrusion molding.
This embodiment is an example in which two connecting panels 13 and 14 are connected.
The connecting panels 13 and 14 have a hollow cross-sectional shape including a plurality of hollow portions 13c, 13d, 14c and 14d, and the connecting portions are shown in FIG.
An example in which a pair of fitting pieces 13a and 13a are provided above and below one connecting panel, and the fitting convex portion 14a of the other connecting panel is fitted and connected between them so that the lower surface has a flush shape. It has become.
Further, the first and second protectors 11 and 12 are also connected to the panel connecting portions 11b and 12b so that the lower surfaces of the connecting portions 13b and 14b are flush with each other.
As a result, the hollow portions of the connecting panels 13 and 14 are connected so as to be sandwiched between the panel connecting portions 11b and 12b having the hollow cross-sectional shape of the first and second protectors 11 and 12.
The protective structure according to the present invention is not limited to such a connecting method, but in such a connecting structure, the impact loaded on the first or second protector is transmitted to each hollow portion, and the vehicle body member 1a and the vehicle body member 1a. It is transmitted to the vehicle body side via the connecting part of the vehicle, and has a high protective effect on in-vehicle objects.

The in-vehicle object 20 is connected by bolts or the like at the lower surface portions 11d, 12d of the panel connecting portions 11b, 12b provided on the first and second protectors connected to the vehicle body members 1a, 1a.
Further, since the upper surface side of the in-vehicle object 20 is fastened so as to be located on the lower surface side of the connecting panels 13 and 14, the load received from the lower surface side of the in-vehicle object 20 is absorbed by the displacement of the hollow portion of the connecting panel. It is protected by.

In this embodiment, the first and second protectors 11 and 12 and the connecting panels 13 and 14 are made of an extruded aluminum alloy, and FIG. 1 shows a case where the extruding direction is the same for the protector and the connecting panel. However, as shown in FIG. 3, the second embodiment is arranged and connected in a direction in which the extrusion direction of the first and second protectors (extending direction of the hollow portion) is orthogonal to the extrusion direction of the connecting panels 15a to 15e. May be good.
In this case, a third protector 16 having a hollow cross-sectional shape may be arranged on both end sides of the first and second protectors 11 and 12.
