Description

  The present invention relates to a vehicle structure including a cargo bed and a safety confirmation device.

  A truck etc. can be mentioned as a vehicle with a loading platform provided with 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 a floor surface of the loading platform, a turning gate (tilting) constituting a side wall of the loading platform, and a turned turning gate are provided on the vehicle body. A vehicle structure is disclosed that includes an elastic stopper that stops against a peripheral portion.

  Even in a vehicle with a loading platform, it is desirable to provide a safety confirmation device for confirming safety behind the vehicle from the viewpoint of preventing accidents. However, a vehicle with a cargo bed 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.

  However, vehicles with cargo platforms are often used in harsh environments such as construction sites, and rear combination lamps (RC lamps) are easily soiled. Moreover, in this structure, since an obstacle etc. are detected via the resin case of RC lamp, there exists a possibility that the detection accuracy of a safety confirmation apparatus may fall.

  Further, when the safety confirmation device is integrated inside the RC lamp, the configuration of the RC lamp becomes complicated, and the productivity of the vehicle including the cost decreases. Further, since the safety confirmation device is integrated with the RC lamp, even if either the RC lamp or the safety confirmation device fails, the entire RC lamp must be disassembled, and maintenance of the RC lamp and the safety confirmation device is performed. Both sexes decrease.

  The present invention has been made in view of the above circumstances, and one of its purposes is to provide a vehicle structure capable of providing a safety confirmation device with a simple configuration and high accuracy in a vehicle having a loading platform. is there.

A vehicle structure according to an aspect of the present invention is as follows.
The floor of the vehicle bed,
A tilting pivotally attached to the outer peripheral edge of the floor, and constituting the wall of the cargo bed;
A vehicle body structure comprising: an elastic stopper that holds the pivoted tilt against the vehicle body periphery;
The elastic stopper includes a storage portion that is recessed from the front end portion to the inward side of the vehicle,
A vehicle safety confirmation device stored in the storage unit is provided.

  In the above configuration, since the safety confirmation device is provided in the storage portion of the elastic stopper, it is resistant to impacts and hardly contaminates. Therefore, it is difficult for problems such as a decrease in detection accuracy of the safety confirmation device to occur.

  Further, in the above configuration, the safety confirmation device can be fixed to the vehicle with a loading platform by using the elastic stopper mounting portion provided in the conventional vehicle structure, so that the safety confirmation device can be easily and inexpensively installed on the vehicle with the loading platform. be able to. Moreover, since an elastic stopper can be easily removed from a vehicle with a loading platform, according to the above configuration, the maintenance performance of the safety confirmation device can be improved.

In addition, this invention is not limited to these illustrations, is shown by the claim, and it is intended that all the changes within the meaning and range equivalent to a claim are included.

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

  The tilt 21 is rotatably attached to the outer peripheral edge of the floor 20 on the vehicle rear side via a hinge 24. Further, the tilt 22 (23) is rotatably attached to the outer peripheral edge portion of the floor portion 20 on the vehicle left side (vehicle right side) 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 by the same fasteners as the fastener 25 described above. By releasing the fixing by the fastener 25, the tilts 21, 22, and 23 in FIG. 1 rotate around the hinge 24 toward the vehicle outer side.

  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 in the vehicle. The vehicle body peripheral portion 3 is a portion facing the pivoted tilts 21, 22, and 23. The elastic stopper 4 is a member that comes into contact with the tilts 21, 22, 23 when the tilts 21, 22, 23 are rotated and prevents the tilts 21, 22, 23 from crashing into the vehicle body periphery 3. . 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 tilts 21, 22, and 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 vehicle front side and the vehicle rear side of the vehicle body periphery on the right side of the vehicle at a position not visible in FIG. Moreover, in the vehicle body periphery 3 on the vehicle rear side, two elastic stoppers 4 are provided on the vehicle left end side and the vehicle right end side on the outer peripheral surface thereof. Here, the number and position of the elastic stoppers 4 are not limited to the illustration of this example. For example, one elastic stopper 4 may be provided on each vehicle body peripheral portion 3 or three or more elastic stoppers 4 may be provided. Further, the elastic stopper 4 may be provided at the center in the width direction of each vehicle body peripheral portion 3.

≪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, sonar, laser radar, and millimeter wave radar. These are devices that detect an object or person existing at a position that is a blind spot of the driver or a position that is difficult to see, and present the detected information to the driver. For example, in the case of a camera, an image of an object / person is presented to the driver. In the case of sonar or laser radar, the presence of an object or person is presented to the driver as an alarm.

  Information from the safety confirmation device 5 is input to an ECU (electric 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 in all the elastic stoppers 4 or may be provided in some elastic stoppers 4. It is preferable that at least one safety confirmation device 5 is provided in 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 | positioning state of the safety confirmation apparatus 5 in the elastic stopper 4 is demonstrated based on FIG. In FIG. 3, the right side of the drawing is the outer side of the vehicle 100 with a loading platform (FIG. 1), and the left side of the drawing 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 is provided with a storage portion 40 that is recessed from the front end portion 41 (right end portion on the paper surface) to the inner side (left side of the paper surface) of the vehicle 100 with a loading platform (FIG. 1). The storage unit 40 may be a through hole or a recess having a bottom. The storage part 40 of this example is a through-hole, and is composed of a large diameter part 40A on the distal end side of the elastic stopper 4 and a small diameter part 40B on the inner side. 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 unit 50, a flange unit 51, a main body unit 52, a screw unit 53, and a nut 54. The camera 5 in the storage unit 40 is preferably installed at a position where the tilts 21, 22 and 23 do not contact the camera 5 even when the elastic stopper 4 is elastically deformed by the collision of the tilts 21, 22 and 23. . The lens unit 50 of this example is completely stored inside the large-diameter portion 40 </ b> A of the storage unit 40 and does not protrude at all from the distal end portion 41 of the elastic stopper 4. Therefore, the lens unit 50 is hardly soiled, and the lens unit 50 is not easily damaged even if the tilts 21, 22, and 23 in FIG. 1 abut on the tip 41 of the elastic stopper 4.

  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 distal end portion 41 side of the elastic stopper 4, the flange portion 51 is stopped 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 is fitted into the mounting hole 3h.

  The screw portion 53 is a member in which a screw groove is formed on the outer periphery of a rod-like body extending from the rear end of the main body portion 52, and the nut 54 is a member that is screwed into the screw groove of the screw portion 53. When the camera 5 is fixed to the vehicle body peripheral portion 3, the screw portion 53 is passed through the through hole 30 h of the base-like bracket 30, and the nut 54 is screwed into the screw portion 53. The inner end surface (the end surface on the right side of the drawing) of the nut 54 is in contact with the end surface of the bracket 30 where the through hole 30 h is provided, and the bracket 5 is tightened with the vehicle body peripheral portion 3. Fixed. In this configuration, the camera 5 itself also functions as a fixing member that fixes the elastic stopper 4 to the vehicle body peripheral portion 3.

≪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. Protected from. Therefore, a large impact is unlikely to act on the safety confirmation device 5 and the safety confirmation device 5 is not easily broken. In addition, since the safety confirmation device 5 is difficult to get dirty, problems such as a decrease in detection accuracy of the safety confirmation device 5 are unlikely to occur. Further, in this example, since 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, the detection of the safety confirmation device 5 is performed. Excellent 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 (the mounting hole 3h in this example) of the elastic stopper 4 provided in the conventional vehicle structure. The safety confirmation device 5 can be installed in a vehicle with a loading platform. Moreover, since the elastic stopper 4 can be easily removed from the vehicle with a loading platform, the 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 of FIG.
