Description

  The present invention relates to a housing structure for a fuel cell system.

  2. Description of the Related Art Conventionally, a fixed piece that extends to the outside of a housing is integrally formed at the lower portion of the housing in the housing of the fuel cell system.

  Thus, the casing of the fuel cell system can be fixed by fixing the fixing piece extending from the casing at the installation location with the bolt to the installation location.

  However, in such a casing structure of the fuel cell system, a fixed piece extending from the casing may be caught on a wall surface or the like when transporting a narrow passage.

  Thereby, there was a problem that importability was bad.

  The present invention has been made in view of such circumstances, and provides a casing structure of a fuel cell system that improves the carryability as compared with the case where a fixed piece is integrated with the casing. Objective.

  In the first aspect, a fixing piece that extends from the casing and fixes the casing to the installation location, or an attachment portion that can be selectively attached to a handle for supporting the casing when it is transported is provided. ing.

  That is, when transporting the casing, the casing can be transported with the fixed piece removed from the mounting portion of the casing. Thereby, compared with the case where a fixed piece is integrally formed in a housing | casing, interference with a fixed piece and another location can be prevented. Thereby, carrying-in property improves.

  During the transportation, the handle can be selectively attached to the attachment portion of the housing. For this reason, it becomes easy to support a housing | casing by attaching a handle to an attaching part, and the further improvement of carrying-in property can be aimed at.

  On the other hand, at the time of fixing, a fixing piece is attached to the mounting portion of the housing. Thereby, a fixed piece can be extended from a housing | casing. And a housing | casing can be fixed to an installation location by fixing this fixing piece to an installation location.

  In the second aspect, the laterally long casing having a lateral width longer than the depth is provided at or near the end in the lateral direction, or near the end in the longitudinal direction or near the end, and extends from the casing. There is provided an attachment portion to which a fixing piece for fixing the device to the installation location is detachably attached.

  That is, when transporting the casing, the casing can be transported with the fixed piece removed from the mounting portion of the casing. Thereby, compared with the case where a fixed piece is integrally formed in a housing | casing, interference with a fixed piece and another location can be prevented. Thereby, carrying-in property improves.

  And at the time of fixation, a fixing piece is attached to the attachment part of a housing | casing. Thereby, since a fixed piece can be extended from a housing | casing, a housing | casing can be fixed to an installation location by fixing this fixed piece to an installation location.

  At this time, the attachment portion is provided at an end portion in the short direction of the housing or in the vicinity of the end portion, or at an end portion in the longitudinal direction or in the vicinity of the end portion. For this reason, for example, when the installation location is set in a narrow passage, and the longitudinal direction of the casing is set to match the length direction of the passage, the mounting provided at or near the end of the longitudinal direction of the casing If a fixed piece is attached to the part, the fixed piece can be extended in the length direction of the passage.

  Thereby, a housing | casing can be fixed to an installation location, avoiding interference of the fixed piece to the wall surface etc. by the side of a channel | path.

  In addition, when the installation location is set in a wide passage, by attaching a fixing piece to the end of the casing in the short direction or the mounting portion provided in the vicinity of the end, the casing can easily fall down. The fixed piece can be extended. Accordingly, it is possible to fix the casing to the installation location while enhancing the effect of preventing the casing from falling and avoiding interference of a fixing piece to the wall or the like on the side of the passage and tools during installation.

  In the third aspect, the attachment portion is set in a reinforcing structure portion that reinforces the casing.

  That is, the attachment portion is provided in the reinforcing structure portion of the housing, and the fixed piece is attached to the reinforcing structure portion that reinforces the housing. For this reason, compared with the case where a fixing piece is attached to parts other than a reinforcement structure part, fixing strength can be raised.

  Further, in the structure in which the handle is attached to the attachment portion, a load applied from the handle at the time of carrying in can be input to the reinforcing structure portion. For this reason, the deformation | transformation of the housing | casing by load input can be suppressed compared with the case where an attaching part is provided in parts other than a reinforcement structure part.

  In the case structure of the fuel cell system according to the first aspect, the carryability can be improved as compared with the case where the fixed piece is integrated with the case.
