Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a mounting structure for a rear confirmation camera installed at the rear of a bus.

<Prior Art> Buses and the like are equipped with a camera at the rear that captures the rear of the vehicle, and when there is no guidance from an assistant, the vehicle backs up while checking with the camera.
This camera is generally mounted on the roof at the rear of the bus or recessed in the rear section.

On the other hand, a rear deflector may be provided at the rear upper part of the roof to rectify the air flow on the surface of the vehicle body while the vehicle is running. Since this rear deflector and the camera are installed at approximately the same location, conventionally, in buses equipped with a rear deflector,
The camera is mounted on the deflector, or as mentioned above, the camera is embedded in the rear side of the vehicle body so that the mounting positions of the two do not overlap.

<Problems to be solved by the invention> When attempting to attach a rear deflector to a vehicle equipped with a television camera, the conventional television camera would protrude above the deflector, causing problems in terms of appearance and mounting structure. undesirable,
In addition, when the camera is stored in the rear of the vehicle, there is an inconvenience that the stored camera protrudes into the interior of the vehicle and comes into contact with the back side of the rearmost seat, making it impossible to recline the rearmost seat sufficiently.

<Means for Solving the Problems> In order to solve the above problems, the present invention provides a rear deflector for rectification provided at the rear end of the roof of the bus, an opening drilled in the rear deflector, and a cover that covers the rear deflector and is supported in an openable/closable manner by the rear deflector and constitutes a part of the rear deflector, and is disposed on the vehicle front side of the opening and between the rear deflector and the roof A driving means attached to the rear surface of the rear deflector, a portion of which is rotatably supported by the rear deflector on the rear side of the vehicle of the opening, and between the rear deflector and the roof and the opening. a camera selectively moved between a retracted state located below and a used state protruding outwardly through the opening; The camera is characterized by a link mechanism connected to the drive mechanism to close the cover when the camera is in the stored state and open the cover when the camera is in use.

<Example> An example of the vehicle rear confirmation camera according to the present invention will be described.

This camera 2 is attached to the rear end of the roof 6 of the bus 4, and can photograph the rear of the bus 4.
Further, as shown in FIG. 2, a rear deflector 8 for air rectification is attached to the rear end of the roof 6.

The rear deflector 8 is provided at the rearmost end of the roof 6 over the entire width of the vehicle, and is fixed on both sides of the bus 4. The front end of the deflector 8 is parallel to the surface of the roof 6, and the rear end of the rear deflector 8 is bent at the rearmost end of the roof 6 and is formed to follow the rear surface of the bus 4.
In other words, the wind that flows from the front to the rear on the roof 6 while the bus 4 is running is rectified in the direction along the rear of the bus 4 by passing between the rear deflector 8 and the roof 6. It's summery.

An opening 10 is formed in the substantially central portion of the rear deflector 8 in the vehicle width direction.
A cover 12 is attached to 0. The cover 12 is supported via a link 16 so as to be rotatable about a pivot point 18, and thus covers the opening 10 in an openable and closable manner. As shown in FIG. 1, the camera 2 is rotatably supported by a link 24 at the rear side of the vehicle body through the opening of the rear deflector 8. As shown in FIG. The camera 2 is arranged between the rear deflector 8 and the roof 6 in the stored state, and is arranged to protrude rearward through the opening 10 of the rear deflector 8 in the used state.

A motor 14 as a driving means is attached to the rear surface of the opening of the rear deflector 8 on the front side of the vehicle body, and one end of a link 28 is coaxially attached to the rotating shaft of this motor 14, and the other end of the link 20 is attached to one end of the link 20. connected.

The other end of the link 20 is connected to the camera 2, and when the link 28 is rotated by the rotation of the motor 14, the link 20 is moved in the longitudinal direction of the vehicle body, so that it is simultaneously moved in the longitudinal direction of the vehicle body. At this time, the camera 2 rotates around the rotation fulcrum 22 of the link 24, so it moves from the stored state to the used state,
Or vice versa, the movement would be through the opening 10. In addition, the rotation fulcrum 22 is the rear deflector 8
Because it is provided on the back side of the rear deflector 8
A notch is provided at a portion that interferes with the rotation of the link 24 (FIG. 4).

One end of a link 26 is connected to the intermediate portion of the link 20, and the other end of the link 26 is connected to the cover 12. The link 26 moves up and down in conjunction with the back and forth movement of the link 20. That is, when the link 20 moves backward, the link 26 pushes the cover 12 upward,
When the link 20 moves forward, the link 26 pulls the cover 12 downward.

Since the camera 2 is configured as described above, when the camera 2 is moved from the storage state to the use state, the motor 14 first rotates the link 28 counterclockwise in the figure, and the link 20 is moved backward. Ru. Then, the camera 2 is connected to the rotation fulcrum 22 by the link 24.
While being rotated around, it is moved rearwardly by the link 20 and projects through the opening 10. At this time, the cover 12 is opened by pushing up the link 26 as the link 20 moves (FIG. 3).

In use, the angle of inclination of the camera 2 is determined by the links 20 and 24, and is held at an optimal angle. Then, a rear image is displayed on a monitor (not shown) installed in a driver's seat or the like.

Further, when the camera 2 is moved from the use state to the storage state, the motor 14 rotates the link 28 in the opposite direction to the above, and the link 20 is moved forward. Then, while the camera 2 is rotated around the pivot point 22 by the link 24, it is moved forward by the link 20 and stored through the opening 10. At this time, the cover 12 is closed by pulling down the link 26 as the link 20 moves.

The link 28 operates a limit switch (not shown) at the position when the camera 2 is in the retracted state and in the used state, and this limit switch cuts off the current supply to the motor 14.

Therefore, since the camera 2 is located higher than in the conventional body retractable type, a wide field of view can be obtained, and since there is no protrusion toward the passenger compartment, the reclining angle of the seat is not restricted. Moreover, since the camera 2 is housed inside the rear deflector 8, there is no need for a cover to prevent dirt on the lens surface, and since the outer panel of the bus 4 body is not processed, rust prevention and waterproof properties will not deteriorate. .

<Effects of the invention> According to the bus rear confirmation camera of the present invention, it is configured to be stored inside the rear deflector and pushed out from there, so the camera position can be set higher than the conventional body retractable type, and the visibility is improved. It's wide enough. Since the camera storage part does not extend into the passenger compartment, the reclining angle of the seat is not restricted. Since the camera is housed inside the rear deflector, there is no need for a separate cover to prevent the lens surface from getting dirty.
