A housing of a railway vehicle device includes a reinforcing member and at least one first exterior member. The reinforcing member includes a first support member extending in a X-axis direction, and second support members that are fixed to the first support member while main surfaces are oriented in a direction intersecting the X-axis direction, the second support members being plate-like members. The first exterior members are thin plate-like members that are fixed to side surfaces of the second support members, cover a periphery of the reinforcing member, and form housing surfaces extending along the X-axis direction. In each of the first exterior members, cutouts each are formed extending in a direction intersecting the X-axis direction from the both ends in the direction intersecting the X-axis direction. An opening is formed, by the cutouts, in at least one of the housing surfaces extending along the X-axis direction.

Casing for railroad vehicle device

An underfloor device includes first and second closed portions. The outer surfaces of the first and second closed portions form a portion of a housing. A portion of the outer surfaces of the first and second closed portions are in contact with an open portion that is a space extending into a vertical direction from an opening formed on the vertically top face of the housing. The portion of the outer surface of the first closed portion in contact with the open portion and the portion of the outer portion of the second closed portion in contact with the open portion are provided with a first connection port and a second connection port, respectively. A first outfitting cable and a second outfitting cable are to be passed through the opening and the open portion, and respectively through the first connection port and the second connection port.

Underfloor device for railway vehicle

An enclosure () has an inner space in which a rectangular parallelepiped shaped device unit () is storable, and has a side surface with an opening () for insertion of the device unit (). A mounting frame () is a flat plate facing the opening () and disposed in the enclosure () on the opposite side of the enclosure () with respect in the opening (). A guide unit includes a slide rail () extending from the mounting frame to the opening, and guides the device unit () between the opening () and the mounting frame () in a state in which the guide unit holds the device unit () in the Y-axis direction.

Unit storage device and railway vehicle

In an interlock system, locking of a second locking mechanism is enabled only when a first key holding part holds a first key and a control device is in a state in which a residual voltage of the control device is not discharged. Application of a power supply voltage to the control device is enabled by switching of a ground switch only when a second key holding part holds a second key. Removal of the second key from the second key holding part is enabled only when the ground switch is in the grounded position and the control device is in a grounded state. Removal of the first key from the first key holding part is enabled only when the control device is in a state in which residual voltage is discharged.

Interlock mechanism for vehicle control device

A control device for a vehicle, the control device including, in a housing that is installed under a floor of the vehicle: a power converter configured of a semiconductor switching circuit; a control unit that controls the output of the power converter so as to supply a required load to a power; a wiring that is connected to the power converter; a voltage detector that detects a voltage applied to the wiring and outputs the detected voltage to the control unit; and a shielding unit that shields radiation noise from the wiring to the voltage detector, wherein the control unit is disposed on a first side of the housing along a traveling direction of the vehicle, the power converter is disposed on a second side of the housing along the traveling direction of the vehicle and the voltage detector is disposed between the power converter and the control unit.

Power converting device for vehicle

A vehicle control apparatus is housed within a housing. A cover covers an opening in the housing. Connecting members connect the cover and the housing. A shaft supporting section of each connecting member supports a shaft. A first extending section extends from a bearing in a direction orthogonal to the shaft. The first extending section and the bearing are rotatable with respect to the shaft supporting section. A stopper is not adjacent to the first extending section in the shaft direction when the first extending section is within a first angle range with respect to the shaft supporting section. The stopper is disposed at a position of sandwiching, with the shaft supporting section, the extending section in the shaft direction by being adjacent to the first extending section in the shaft direction, when the first extending section is within a second angle range with respect to the shaft supporting section.

Vehicle control apparatus

A vehicle control device includes a casing that is mounted on a vehicle of an electric vehicle, a machine installing chamber that is provided in the casing and in which a machine that controls the electric vehicle is installed, an air circulating chamber that is provided on a vehicle center side in the casing, a partition plate in which a first through hole that is formed on a side of a top surface of the casing and allows an air a in the machine installing chamber to flow in the air circulating chamber and a second through hole that is formed on a side of a bottom surface of the casing and allows an air in the air circulating chamber to flow in the machine installing chamber are formed, and a radiator radiates heat of an air that flows via the first through hole in the air circulating chamber.

Vehicle control device

There is provided a vehicle controller that is mounted in a box-shaped manner beneath the floor or on the roof of a vehicle so as to supply electric power to vehicle apparatuses. The vehicle controller is configured with a plurality of functional modules; each of the functional moduleshas at one side thereof an interface sidein which a first interface regionwhere signal-line terminals are arranged and a second interface regionwhere power-line terminals are arranged are separated; in each of the interface sides, the first interface regionis disposed in the vicinity of one and the same end and the second interface regionis disposed in the vicinity of the other and the same end; the plurality of functional modules includes a monitoring circuit, an overvoltage protection circuit, and an inverter.

Vehicle controller

A vehicle control device includes plural functional modules each of which is a minimum part unit that contributes to change in input/output potentials, and has an input and an output of one power line or one set of power lines, except for power lines having a same potential as that on an overhead wire side or that on a ground side. The functional module has an interface surface on one side surface, to which both of a signal line and the power line are connected. Each interface surface is divided into a first interface area in which a signal line terminal connected to the signal line is placed, and a second interface area in which a power line terminal connected to the power line is placed. The plural functional modules are adjacently arranged such that the interface surfaces face in a same direction, the first interface areas are located on one end side in common, and the second interface areas are located on the other end side in common.
