Description

  The present invention relates to a vehicle rearward confirmation device.

  In recent years, vehicles such as wagons have been equipped with a camera for confirming the rear of the back door in order to eliminate blind spots behind the vehicle so that the images taken by the camera can be confirmed on the monitor inside the vehicle. Although there are some cameras, this type of camera is usually mounted on the tip of a stay that projects substantially horizontally from the upper part of the back door toward the rear of the vehicle.

As prior art document information related to this type of camera for rearward confirmation, there is the following Patent Document 1 and the like.
JP-A-10-71890

  However, in an off-road car equipped with a spare tire on the back door, the spare tire is reflected in the field of view of the camera even if a rear-facing camera is installed on the back door. In many cases, the rear part of the vehicle has a slightly inclined design compared to a wagon car or the like, so it is sometimes difficult to project the vicinity of the rear bumper, which is the rearmost part of the vehicle, from the upper part of the back door.

  Furthermore, in the type in which the camera is supported by the stay, the camera protrudes from the outer shape of the vehicle body as a projecting object, so that when the vehicle moves backward, the camera may come into contact with an unexpected high place structure or inadvertently in the garage. When the back door is flipped up, the camera may hit the ceiling. If the camera interferes with the surrounding structure, the external impact force directly against the bare camera. In some cases, the camera is easily damaged.

  The present invention has been made in view of the above circumstances, and even a vehicle equipped with a spare tire on the back of the vehicle body via a spare tire carrier can be used to photograph the rear of the vehicle well with a camera. An object of the present invention is to avoid the interference between the camera and surrounding structures as much as possible and to reliably protect an expensive camera even if an external impact force is applied due to the interference or the like.

  The present invention relates to a vehicle rear confirmation device in which a spare tire is mounted on the back of a vehicle body via a spare tire carrier, and is attached to the rear of the vehicle through a hub hole of the wheel when the spare tire is fastened to the spare tire carrier. A box-shaped storage bracket is provided, and a camera for rearward confirmation is stored in the storage bracket downward, and an opening for photographing is formed at a position facing the camera of the storage bracket, and the wheel cover of the spare tire In addition, a window portion aligned with the opening portion is formed.

  Thus, since it becomes possible to take a picture of the lower position from the window portion of the wheel cover of the spare tire with the camera in this way, the situation that the spare tire is reflected in the field of view of the camera and gets in the way. Even if the rear part of the vehicle is designed to be slightly inclined compared to a wagon car, etc., if it is from the window part of the wheel cover of the spare tire, the vicinity of the rear bumper that is the rearmost part of the vehicle can be photographed well It becomes possible.

  Moreover, since the camera does not protrude from the outer shape of the vehicle body as a projecting object, the possibility of the camera interfering with surrounding structures when the vehicle is retracted or the back door is flipped up and down is greatly reduced. Even if external impact force is applied due to interference, etc., the camera is housed in the housing bracket so that it does not receive direct external impact force, so it is possible to protect expensive cameras from damage. It becomes.

  According to the vehicle rear confirmation apparatus of the present invention described above, even if the vehicle is equipped with a spare tire on the back of the vehicle body via a spare tire carrier, the rear of the vehicle can be photographed satisfactorily by the camera. In addition, it is possible to achieve an excellent effect that it is possible to avoid the interference between the camera and the surrounding structure as much as possible, and to reliably protect the expensive camera even if an external impact force is applied due to the interference or the like.

  Embodiments of the present invention will be described below with reference to the drawings.

  1 to 4 show an example of an embodiment for carrying out the present invention. In the vehicle illustrated in FIG. 1, a spare tire 2 is mounted on the back door 1 at the rear of the vehicle body as a backpack. The spare tire 2 is fixed to a spare tire carrier 3 attached to the back door 1 as shown in FIG.

  That is, as shown in FIG. 3, a plurality (three in the figure) of wheel mounting bolts 4 project from the rear end face of the spare tire carrier 3, and each wheel mounting bolt 4 is connected to the wheel 5 in the spare tire 2. The spare tire 2 is fixed to the spare tire carrier 3 by passing through the wheel hole 6 and tightening with the wheel nut 7.

  At this time, in the present embodiment, the rear portion of the spare tire carrier 3 is surrounded by the wheel mounting bolts 4 at the center portion, and when the wheel 5 of the spare tire 2 is fastened, the hub 5 of the wheel 5 is passed through the rear of the vehicle. An overhanging box-shaped storage bracket 9 is provided, and a camera 10 for rearward confirmation is housed downward in the storage bracket 9.

  The housing bracket 9 is composed of two parts, an upper bracket 9a and a lower bracket 9b. The camera 10 is attached to the lower bracket 9b side of the housing bracket 9 with a bolt 12 and a nut 13 via a holder 11. An opening 9c for photographing is formed at a position facing the camera 10 in the lower bracket 9b.

  That is, the rear portion of the lower bracket 9b in which the photographing opening 9c is formed has an inclined surface that forms an upward gradient toward the rear of the vehicle, and the camera 10 disposed substantially perpendicular to the inclined surface. Thus, the lower position of the rear part of the vehicle body can be photographed. At this time, if the camera 10 is arranged in the housing bracket 9 so as not to protrude outward from the inclined surface, it is possible to avoid damage to the camera 10 when the spare tire 2 is detached or attached.

  The front end portion of the lower bracket 9b is attached to the rear end surface of the spare tire carrier 3 with bolts 14 and nuts 15, and the rear end portion of the lower bracket 9b is connected to the rear end portion of the upper bracket 9a with bolts 16 and nuts. The lower bracket 9b can be appropriately attached and detached for the attachment of the camera 10, the maintenance inspection, and the like.

  Further, the wheel cover 18 (see FIG. 4) is covered on the disk portion of the foil 5 so that the wheel mounting bolt 4, the wheel nut 7, and the hub hole 8 are not exposed. 18 is also formed with a window portion 19 aligned with the opening 9c of the lower bracket 9b.

  The portion of the wheel cover 18 where the window portion 19 is formed is also inclined like the rear portion of the lower bracket 9b, and the upper portion sandwiching the inclined surface is behind the vehicle relative to the lower portion. An overhang shape is formed so as to protrude to the top (see FIG. 3), and by placing the camera 10 at the rear end of the vehicle as much as possible, more optimal shooting can be performed.

  Thus, since the camera 10 can take a picture of the lower position from the window 19 of the wheel cover 18 of the spare tire 2 in this way, the spare tire 2 is reflected in the field of view of the camera 10. Even if the rear part of the vehicle has a slightly inclined design as compared with a wagon car or the like, if it is from the window 19 of the wheel cover 18 of the spare tire 2, the rear end of the vehicle As a result, it is possible to satisfactorily photograph the vicinity of the rear bumper 20 (see FIG. 1). It should be noted that even when the rear end of the vehicle is the spare tire 2, it is a matter of course that the lower position of the spare tire 2 can be photographed satisfactorily.

  In addition, since the camera 10 does not protrude from the outer shape of the vehicle body as a projecting object, the possibility that the camera 10 may interfere with surrounding structures when the vehicle is retracted or when the back door 1 is flipped up and down is greatly reduced. Thus, even if an external impact force is applied due to interference or the like, the expensive camera 10 is not damaged because the camera 10 is housed in the housing bracket 9 so as not to receive a direct external impact force. It becomes possible to protect.

  Therefore, according to the above-described embodiment, even if the vehicle is equipped with the spare tire 2 on the back of the vehicle body via the spare tire carrier 3, the rear of the vehicle can be photographed satisfactorily by the camera 10, and the camera The expensive camera 10 can be reliably protected even if an external impact force is applied due to interference or the like as much as possible to avoid interference between the peripheral structure 10 and the peripheral structure.

  It should be noted that the vehicle rearward confirmation device of the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention.

It is a perspective view which shows an example of the form which implements this invention. It is a perspective view of the spare tire carrier for fixing a spare tire. It is sectional drawing which shows the installation state of a camera. It is a perspective view which shows the detail of a wheel cover.
