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 TV camera, the TV camera would conventionally protrude above the deflector, which would make the appearance and installation difficult. Structurally 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 has a rear deflector for rectification provided at the rear end of the roof of the bus, and a rear deflector for the rear roof covered by the rear deflector. A drive member having an actuating part that is disposed and movable toward an opening formed in the rear deflector and a drive mechanism that drives the actuating part, and covers the opening of the rear deflector and forms a part of the rear deflector. a cover part that is supported together with the cover part at the tip of the actuating part and allows the rear of the bus body to be confirmed at a storage position between the rear deflector and the rear end of the roof or on the outside of the rear deflector by the drive mechanism; A retractable back-eye camera including a camera that can be moved to a protruding position has been constructed.

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

This camera 2 is mounted on the rear roof 6 of the bus 4, and photographs the rear of the bus 4.
Further, a rear deflector 8 for rectification is installed on the rear roof 6 of the bus 4, as shown in FIG.
The rear deflector 8 is located at the rearmost end of the roof 6 of the bus 4 and extends over the entire width of the roof 6.
is fixed on both sides. The front end of this rear deflector 8 runs parallel to the roof 6, and is bent at the rear so as to follow the rear side surface of the bus 4. In other words, when the bus 4 is running and wind flows from the front to the rear, the airflow on the roof 6 is rectified.

The camera 2 is connected to the rear deflector 8 and the roof 6.
The rear deflector 8 is housed between the rear deflector 8 and the rear deflector 8, and protrudes from the opening 10 of the rear deflector 8. Next, a detailed explanation will be given using FIG. 1. Reference numeral 12 denotes a cover provided on the opening 10, and this cover 12 is fixed to the top surface of the camera 2. Camera 2 is connected to link 16 and is actuated by link 16. The link 16 as an operating portion is each composed of a pair of parallel main links 18, 18 and sub links 20, 20. The base end portions of the main link 18 and the sub link 20 are each rotatably supported by a support portion 22 fixed to the vehicle body. At the tips of the main link 18 and the sub link 20, there are brackets 21, 2 erected from the inner surface of the cover 12 toward the vehicle body.
1 is rotatably supported. The camera 2 is supported between the brackets 21 and 21, and furthermore, as shown in FIG.
A gear 26 is provided on a shaft 24 connecting the base ends of the motor 18, and the rotation of the motor 28 is transmitted via a gear box 30 for deceleration and a small gear 32 that meshes with the gear 26, thereby forming a drive mechanism. Further, the support portion 22 is provided with a stopper portion 34 that restricts rotation of the link 16.

Next, the operation will be explained based on FIG.

When rear confirmation is not required, the cover 12 covers the opening 10 of the rear deflector 8, and the camera 2 is in the retracted position. When it is necessary to check the rear, when the power is connected to the motor 28 in conjunction with the passenger's switch operation, the motor 28
8 is transmitted via the small gear 32, gear 26, and shaft 24, the main link 18 and the sub link 20 are rotated clockwise in FIG. 1, the cover 12 and the camera 2 are gradually pushed out, and the camera 2 is moved to a protruding position where the rear of the vehicle body can be confirmed. Then, the rotation of the motor 28 is controlled to be stopped by a limit switch or the like (not shown). At this time, as shown in FIG. 3, the main link 18 and the stopper 34 come into contact with each other, so that the inclination angle of the camera 2 is regulated and the camera 2 is held at an optimal position. As a result, an image of the rear of the vehicle can be displayed on a monitor (not shown) provided near the driver's seat. Furthermore, in this embodiment, the explanation has been made using a motor as the drive source of the drive mechanism, but the invention is not limited to this, and the shaft 24 connected to the main link 18
A lever is provided at the link 1, and the rod of the fluid actuator is connected to the lever.
6 may be rotated.

Therefore, compared to the conventional body retractable type, the camera 2 is located higher, providing a wider field of view, and since there is no protrusion toward the passenger compartment, the reclining angle of the seat is not restricted. Furthermore, since the camera 2 is housed within the rear deflector 8, a cover for preventing dirt on the lens surface is not required, and the system can be simplified.

<Effects of the invention> According to the bus rear confirmation camera of this 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, improving visibility. 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.
