Description

The present invention relates to a vehicle structure including a loading platform and a safety confirmation device.

A truck or the like can be mentioned as a vehicle with a loading platform having a loading platform at the rear of the vehicle. For example, in Patent Document 1, as a vehicle structure of a vehicle with a loading platform, a floor portion constituting the floor surface of the loading platform, a rotating gate (tilt) forming a side wall of the loading platform, and a rotated rotating gate are used as a vehicle body. A vehicle structure including an elastic stopper that holds the peripheral portion against the peripheral portion is disclosed.

From the viewpoint of accident prevention, it is desirable to provide a safety confirmation device for confirming the safety behind the vehicle even for vehicles with a loading platform. However, the vehicle with a loading platform has few resin parts, and a safety confirmation device cannot be easily provided. Therefore, Patent Document 2 proposes to provide a rear confirmation device (safety confirmation device) such as a camera inside the rear combination lamp.

<Embodiment 1>
≪Overall composition≫
The truck (vehicle with a loading platform 100) shown in FIG. 1 includes a vehicle structure 1 having a loading platform 2 on the rear side of the vehicle. The loading platform 2 includes a floor portion 20 and three flaps 21, 22, 23 that are rotatably attached to the outer peripheral edge portion of the floor portion 20 and constitute a wall portion of the loading platform 2. The number of tilts in the vehicle structure 1 is not particularly limited, and for example, a configuration may include only the tilts 21 on the rear side of the vehicle.

The tilt 21 is rotatably attached to the outer peripheral edge of the floor 20 on the rear side of the vehicle via a hinge 24. Further, the tilt 22 (23) is rotatably attached to the outer peripheral edge of the floor 20 on the left side of the vehicle (right side of the vehicle) via a hinge 24.

The tilt 21 and the tilt 22 are fixed by a fastener 25 as shown in FIG. Although not shown, the tilt 21 and the tilt 23 (FIG. 1) are also fixed with the same fasteners as the fastener 25. By releasing the fixing by the fastener 25, the tilts 21, 22, and 23 in FIG. 1 rotate toward the outside of the vehicle around the hinge 24.

In the vehicle structure 1, the elastic stopper 4 is provided on the outer peripheral surface of the vehicle body peripheral portion 3 located below the floor portion 20 of the vehicle. The vehicle body peripheral portion 3 is a portion facing the rotated tilts 21, 22, and 23. The elastic stopper 4 is a member that abuts on the flaps 21, 22, 23 when the flaps 21, 22, and 23 are rotated, and prevents the flaps 21, 22, 23 from colliding with the peripheral portion 3 of the vehicle body. .. In view of its function, the elastic stopper 4 is made of an elastic body, typically rubber. Here, unlike this example, the elastic stopper 4 may be provided on the side of the tilt 21, 22, 23.

In this example, as shown in FIG. 1, two elastic stoppers 4 are provided on the vehicle front side and the vehicle rear side on the outer peripheral surface of the vehicle body peripheral portion 3 on the left side of the vehicle. Similarly, two elastic stoppers are provided on the front side of the vehicle and the rear side of the vehicle at the peripheral portion of the vehicle body on the right side of the vehicle, which is not visible in FIG. Further, in the vehicle body peripheral portion 3 on the rear side of the vehicle, two elastic stoppers 4 are provided on the left end side of the vehicle and the right end side of the vehicle on the outer peripheral surface thereof. Here, the number and position of the elastic stopper 4 are not limited to the examples of this example. For example, one elastic stopper 4 may be provided on each peripheral portion 3 of the vehicle body, or three or more elastic stoppers 4 may be provided. Further, the elastic stopper 4 may be provided at the center of each vehicle body peripheral portion 3 in the width direction.

≪Safety confirmation device≫
The vehicle structure 1 of this example further includes a safety confirmation device 5 built in the elastic stopper 4. Examples of the safety confirmation device 5 include a camera, a sonar, a laser radar, a millimeter wave radar, and the like. These are devices that detect objects / people that are in a blind spot or a position that is difficult to see, and present the detection information to the driver. For example, in the case of a camera, an image of an object or person is presented to the driver. In the case of sonar or laser radar, the presence of objects or people is presented to the driver as an alarm.

The information from the safety confirmation device 5 is input to the ECU (electronic control unit) by a wired transmission device such as a wire harness or a wireless transmission device such as Bluetooth (registered trademark). The input information is processed by the ECU and presented to the driver.

The safety confirmation device 5 may be provided on all elastic stoppers 4, or may be provided on some elastic stoppers 4. It is preferable that at least one safety confirmation device 5 is provided for each of the elastic stopper 4 on the left side of the vehicle, the elastic stopper 4 on the right side of the vehicle, and the elastic stopper 4 on the rear side of the vehicle.

Next, the arrangement state of the safety confirmation device 5 in the elastic stopper 4 will be described with reference to FIG. In FIG. 3, the right side of the paper is the outer side of the vehicle 100 with a loading platform (FIG. 1), and the left side of the paper is the inner side of the vehicle 100 with a loading platform. The safety confirmation device 5 in FIG. 3 is a camera.

First, the elastic stopper 4 in which the camera 5 is built includes a storage portion 40 that is recessed from the tip portion 41 (right end portion of the paper surface) into the inner side (left side of the paper surface) of the vehicle with a loading platform 100 (FIG. 1). The storage portion 40 may be a through hole or a recess having a bottom. The storage portion 40 of this example is a through hole, and is composed of a large diameter portion 40A on the tip end side and a small diameter portion 40B on the inner side of the elastic stopper 4. The large diameter portion 40A and the small diameter portion 40B each have a constant inner diameter, and a step is formed at the boundary between the large diameter portion 40A and the small diameter portion 40B.

On the other hand, the camera 5 includes a lens portion 50, a flange portion 51, a main body portion 52, a screw portion 53, and a nut 54. As for the camera 5 in the storage portion 40, it is preferable to install the camera 5 at a position where the tilts 21, 22 and 23 do not come into contact with the camera 5 even when the elastic stopper 4 is elastically deformed due to the collision of the tilts 21 and 22,23. .. The lens portion 50 of this example is completely housed inside the large diameter portion 40A of the storage portion 40, and does not protrude at all from the tip portion 41 of the elastic stopper 4. Therefore, the lens portion 50 is less likely to be soiled, and even if the tilts 21, 22, and 23 of FIG. 1 come into contact with the tip portion 41 of the elastic stopper 4, the lens portion 50 is less likely to be damaged.

The flange portion 51 has an outer diameter that is larger than the inner diameter of the small diameter portion 40B of the storage portion 40 and smaller than the inner diameter of the large diameter portion 40A. Therefore, when the camera 5 is inserted from the tip 41 side of the elastic stopper 4, the flange portion 51 is pressed against the step between the large diameter portion 40A and the small diameter portion 40B, and the position of the camera 5 in the storage portion 40 is determined.

The main body 52 is a portion in which an image sensor and an image processor are built, and has an outer diameter smaller than the small diameter portion 40B of the storage portion 40 and the mounting hole 3h of the vehicle body peripheral portion 3. Therefore, the main body 52 fits into the mounting hole 3h.

The screw portion 53 is a member having a thread groove formed on the outer periphery of a rod-shaped body extending from the rear end of the main body portion 52, and the nut 54 is a member screwed into the screw groove of the screw portion 53. When fixing the camera 5 to the peripheral portion 3 of the vehicle body, the screw portion 53 is passed through the through hole 30h of the trapezoidal bracket 30, and the nut 54 is screwed into the screw portion 53. The inner end surface of the nut 54 (the end surface on the right side of the paper surface) comes into contact with the end surface of the bracket 30 where the through hole 30h is provided, and the bracket 30 is tightened with the vehicle body peripheral portion 3, so that the camera 5 is attached to the vehicle body peripheral portion 3. It is fixed. In this configuration, the camera 5 itself also functions as a fixing member for fixing the elastic stopper 4 to the peripheral portion 3 of the vehicle body.

≪Effect≫
In the configuration described above, the safety confirmation device 5 is provided in the storage portion 40 of the elastic stopper 4, in other words, the safety confirmation device 5 is surrounded by the elastic stopper 4, so that the safety confirmation device 5 is in an external environment to some extent. Protected from. Therefore, it is difficult for a large impact to act on the safety confirmation device 5, and the safety confirmation device 5 is not easily broken. Further, since the safety confirmation device 5 is not easily soiled, problems such as a decrease in the detection accuracy of the safety confirmation device 5 are unlikely to occur. Further, in this example, the entire surface of the detection unit (lens unit 50 in this example) of the safety confirmation device 5 is exposed from the storage unit 40, and the detection unit is not covered with a case or the like. Excellent in accuracy.

Further, in the above configuration, the safety confirmation device 5 can be fixed to the vehicle with a loading platform by using the mounting portion (mounting hole 3h in this example) of the elastic stopper 4 which is also provided in the conventional vehicle structure, so that it is inexpensive and easy. The safety confirmation device 5 can be installed on a vehicle with a loading platform. Further, since the elastic stopper 4 can be easily removed from the vehicle with a loading platform, maintenance of the safety confirmation device 5 can be easily performed. In this example, the safety confirmation device 5 can be removed simply by loosening the nut 54 in FIG.
