Abstract

(57) [Summary] [Purpose] The rear camera for rear view of the bus is normally stored to eliminate problems such as air resistance when driving, appearance and dirt on the lens. Be able to project a sufficiently large area behind you. [Structure] A part of a rear spoiler 1 provided on a rear portion of a roof of a bus is used as a movable part 12, a back camera 4 is attached below the movable part 12, and the movable part 12 and the back camera 4 are rotated up and down together by an operation of a geared motor 6. In the position shown by the solid line in which the movable part 12 is flush with the fixed part, the back camera 4 is housed in the rear spoiler 1 and is movable.
When 2 and the back camera 4 are rotated to the positions shown by the chain line, they are in a use position where a wide rear area is imaged.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a back camera mounting structure for a bus.

[0002]

[Prior Art]

 Buses equipped with a back camera (television camera) and displaying their images on the display (CRT) for rearward confirmation have been used.

Conventionally, as shown in FIG. 4, a back camera a is generally attached to a central portion of a rear end of a bus roof via a bracket b.

Also, as disclosed in Japanese Utility Model Laid-Open No. 19740/1993, a camera in which a back camera is attached to a rear wall surface of a vehicle body so as to be retractable is also being developed.

[0005]

[Problems to be solved by the device]

 As shown in Fig. 4, the conventional camera with the back camera mounted on the roof is not preferable in terms of air resistance and appearance when driving because the bracket and back camera always project on the roof. However, there is a problem that the lens is constantly exposed to wind and rain and dust.

Further, in the case where the back camera is attached to the rear wall surface of the vehicle body so as to be retractable, the back camera projects from the rear wall surface of the vehicle body only when the back gear is turned on, which requires rearward confirmation, and is stored otherwise. Since it is in the state, there is no problem with air resistance during driving, appearance and dirt on the lens, but since the mounting position is below the rear window glass, the back camera compared to the one installed on the roof. The problem is that the height of the camera is considerably low, and the range that can be captured by the back camera is narrowed.

The present invention is mainly aimed at addressing the above-mentioned conventional problems.

[0008]

[Means for Solving the Problems]

 In the present invention, in a bus in which a rear spoiler is attached to the upper rear part of the roof, a part of the rear spoiler is provided as a movable part that can be vertically rotated, and a back camera is vertically rotated together with the movable part below the movable part. It is characterized in that it is mounted so as to have an actuator for controlling these rotations.

[0009]

[Action]

 Due to the above, the movable part of the rear spoiler is in the lowered position and is flush with the fixed part of the rear spoiler to perform the rear spoiler function as a whole.In normal operation, the back camera is stored under the movable part. Yes, problems such as air resistance during running, appearance and lens contamination do not occur. When the actuator is actuated when the bus moves backwards, both the moving parts and the back camera rotate upward, and the back camera catches the rear of the bus from a high position on the roof, which makes it possible to check the rear when moving backwards with good functionality.

[0010]

【Example】

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

FIG. 1 is an external perspective view of the upper rear part of the bus. 1 is a rear spoiler provided on the rear part of the roof 2 and 3 is a rear window glass. The rear spoiler 1 is divided into left and right fixed parts 11 and 11 and a central movable part 12 in three parts. The fixed parts 11 and 11 are fixed to the roof 2, and only the movable part 12 rotates up and down around the front end part. The back camera 4 is attached to the lower part of the movable part 12 so as to be possible.

A concrete structural example of the movable portion 12 and the back camera 4 attached thereto is as shown in FIGS. 2 and 3.

That is, the hinge bracket 21 is fixedly mounted on the rear upper surface of the roof 2, and the mounting shaft 51 fixed to the rear end of the support arm 5 of the back camera 4 is rotatably mounted on the hinge bracket 21. The upper surface of the back camera 4 is bonded and fixed to the lower surface of the rear portion of the movable portion 12 of the rear spoiler 1, and the movable portion 12 and the back camera 4 are integrally configured to rotate up and down about the mounting shaft 51. There is.

A geared motor 6 is mounted on a portion of the roof 2 which is covered by the movable portion 12, and an output shaft 61 of the geared motor 6 and the support arm 5 are connected by links 7 and 8. The rotation of the geared motor 6 causes the movable portion 12 and the back camera 4 to rotate up and down via the links 7 and 8.

In the above description, when the movable portion 12 is in the lowered position in which the movable portion 12 is flush with the left and right fixed portions 11 and 11 as shown by the solid line in FIG. 2, the rear spoiler 1 as a whole is rectified during high speed running. The back camera 4 is stored in the lower part of the movable portion 12 of the rear spoiler 1 by fulfilling a conventionally known spoiler function such as a function.

When rearward confirmation is required, the geared motor 6 rotates in one direction when the ascending switch is turned on manually or in conjunction with turning on the back gear, and the supporting arm 5 is moved upward through the links 7 and 8. 2 to reach the use position shown by the chain line in FIG. 2, the geared motor 6 stops, and the image of the rear of the bus captured by the back camera 4 is displayed on the display of the driver's cab so that rear confirmation can be performed. ..

When the backward movement of the bus is completed and the descending switch is turned on in conjunction with the manual operation or a gear operation other than the back gear, the geared motor 6 rotates in the opposite direction to the above, and the movable portion 12 and the back camera 4 are rotated. Is lowered to the position shown by the solid line in FIG. 2, the geared motor 6 is stopped.

As described above, the back camera 4 is rotationally controlled between the storage position and the use position.

In the above embodiment, the movable arm 12 is rotated vertically by rotating the support arm 5 of the back camera 4 up and down. The front end portion is rotatably attached to the hinge bracket 21, and the movable portion 12 is vertically rotated by the geared motor 6, whereby the back camera 4 fixed to the lower surface portion of the movable portion 12 is moved. It may be configured to rotate together with and to be in the use position and the storage position.

Further, the power means for rotating the movable part 12 and the back camera 4 is not limited to the geared motor 6 shown in the figure, but any actuator can be adopted.

[0021]

[Effect of the device]

 As described above, according to the present invention, the rear spoiler provided on the rear part of the roof is used, a part of the rear spoiler is used as a movable part, and the back camera is incorporated therein, and the movable part of the rear spoiler is rotated upward. The rear camera is stored in the rear spoiler during normal operation without the need for rearward confirmation, which improves the appearance and prevents the lens from becoming dirty. Since the height is high at the position, the rear confirmable range is sufficiently wide, and the rear visibility can be improved, and in combination with the simple structure and cost reduction, it can bring great effects in practical use. ..
