Definitions
- the present invention relates to a cab and a work machine.
- a controller of a work vehicle is often arranged centrally behind a driver's seat in a driver's cab since an operation condition of the controller associated with a vehicle operation can be confirmed instantly.
- the controller is accommodated in an oblong case collectively with equipment such as an MPU (Micro Processing Unit) associated with a certain function.
- the controller has on its outer surface a connector for connection of a cable or the like for communication with other equipment.
- Such an arrangement of a controller is disclosed in Japanese Patent Laying-Open No. 2014-136951. According to this publication, two controllers are arranged in a longitudinal direction at a panel portion behind a driver's seat.
- PTD 1 Japanese Patent Laying-Open No. 2014-136951
- controllers have been increased because of advancement in functions of a work vehicle (for example, information-oriented construction, surrounding monitoring function, and the like) in recent years. Therefore, there is a problem that attaching and arranging of controllers will be difficult in view of securing a space.
- the present invention was made to solve the problem described above, and its object is to provide a cab and a work machine to facilitate attaching and arranging controllers even when the number of controllers is increased.
- a cab of the present invention comprises a floor portion, a base, a driver's seat, a back panel, and a controller main body.
- the base is arranged on the floor portion.
- the driver's seat is arranged on the base.
- the back panel is arranged behind the driver's seat.
- the base has a bracket extending toward the back panel.
- the controller main body is arranged between the base and the back panel and fixed to the bracket. In a plan view, at least a part of the controller main body is located between the base and the floor portion so as to overlap with the base, and a fixing part fixing the controller main body to the bracket is arranged between a rear end of the base and the back panel.
- the controller main body is arranged so as to overlap with the base in a plan view. Therefore, the main body can be arranged on a front side of the cab, and a large space can be secured between the controller main body and the back panel. Accordingly, a cable can be readily arranged in the space.
- the fixing part fixing the controller main body to the bracket is arranged at a position between a rear end of the base and the back panel so as not to overlap with the base. Therefore, the controller main body can be fixed to the bracket from above.
- the controller main body can be arranged in the space between the driver's seat and the back panel, and an operation of attaching the controller main body can be readily performed even in a narrow space between the driver's seat and the back panel.
- a cover is further provided which covers an upper part of a portion of the controller main body located between a rear end of the base and the back panel in a plan view.

Abstract
Description
- The present invention relates to a cab and a work machine.
- A controller of a work vehicle is often arranged centrally behind a driver's seat in a driver's cab since an operation condition of the controller associated with a vehicle operation can be confirmed instantly. The controller is accommodated in an oblong case collectively with equipment such as an MPU (Micro Processing Unit) associated with a certain function. The controller has on its outer surface a connector for connection of a cable or the like for communication with other equipment.
- Such an arrangement of a controller is disclosed in Japanese Patent Laying-Open No. 2014-136951. According to this publication, two controllers are arranged in a longitudinal direction at a panel portion behind a driver's seat.
- However, the number of controllers has been increased because of advancement in functions of a work vehicle (for example, information-oriented construction, surrounding monitoring function, and the like) in recent years. Therefore, there is a problem that attaching and arranging of controllers will be difficult in view of securing a space.
- The present invention was made to solve the problem described above, and its object is to provide a cab and a work machine to facilitate attaching and arranging controllers even when the number of controllers is increased.
- A cab of the present invention comprises a floor portion, a base, a driver's seat, a back panel, and a controller main body. The base is arranged on the floor portion. The driver's seat is arranged on the base. The back panel is arranged behind the driver's seat. The base has a bracket extending toward the back panel. The controller main body is arranged between the base and the back panel and fixed to the bracket. In a plan view, at least a part of the controller main body is located between the base and the floor portion so as to overlap with the base, and a fixing part fixing the controller main body to the bracket is arranged between a rear end of the base and the back panel.
- According to the cab of the present invention, at least a part of the controller main body is arranged so as to overlap with the base in a plan view. Therefore, the main body can be arranged on a front side of the cab, and a large space can be secured between the controller main body and the back panel. Accordingly, a cable can be readily arranged in the space.
- Moreover, the fixing part fixing the controller main body to the bracket is arranged at a position between a rear end of the base and the back panel so as not to overlap with the base. Therefore, the controller main body can be fixed to the bracket from above.
- According to the configuration described above, the controller main body can be arranged in the space between the driver's seat and the back panel, and an operation of attaching the controller main body can be readily performed even in a narrow space between the driver's seat and the back panel.
- In the cab described above, a cover is further provided which covers an upper part of a portion of the controller main body located between a rear end of the base and the back panel in a plan view.
- Accordingly, adhesion of water or dust to the controller main body can be suppressed by the cover, so that the controller main body can be protected.
- In the cab described above, the cover constitutes at least a part of a duct connecting a first ventilating hole provided at the base and a second ventilating hole provided at the back panel.
- Accordingly, a protective member for the controller main body and the duct connecting the first ventilating hole and the second ventilating hole can be formed with an integrated cover. Moreover, by attaching the cover, the protective member protecting the controller main body and the duct can be made at the same time, so that assembling can be readily performed.
- In the cab described above, the controller main body has a connector, and the connector is arranged at a face of the controller main body on a side of the back panel.
- According to the cab described above, a large space can be secured between the controller main body and the back panel. Therefore, even when a connector is provided at the face of the controller main body on the side of the back panel, a cable can be readily connected to the connector.
- In the cab described above, the base has a vertical plate extending from a side of the driver's seat to a side of the floor portion. The bracket has a vertical plate part extending along the vertical plate and attached to the vertical plate, and a horizontal plate part extending from an upper end of the vertical plate part toward the back panel.
- By attaching the controller main body on the horizontal plate part, the controller main body can be arranged at a height apart from the floor portion. Accordingly, since a height of the controller main body can be secured, the controller main body is prevented from being soaked in water when the floor portion is washed with water. Moreover, when the controller main body is fixed to the bracket, the controller main body can be held in the state of being placed on the horizontal plate part. Therefore, an operation of fixing the controller main body to the bracket can be readily performed.
- In the cab described above, a cable is further provided which is connected to the controller main body and transmits a video signal acquired from a camera. The cable penetrates through the floor portion and extends from inside to outside of the cab.
- Accordingly, a signal of an image captured outside of the cab can be processed by the controller main body arranged inside of the cab.
- A work machine of the present invention has any one of the cabs described above.
- According to the work machine of the present invention, attaching and arranging of the controller can be readily performed even when the number of controllers is increased.
- As described above, according to the present invention, a cab and a work machine can be achieved which facilitates attaching and arranging of a controller even when the number of controllers is increased.
