[0003] [[Patent Document 1]] Japanese Unexamined Patent Publication No. 2014-230360 [[Summary of the Invention]] [[Problem to be Solved by the Invention]]

[0004] Some uninterruptible power supply devices, between vertical installation types (e.g., stationary types) and horizontal installation types (e.g., rack-mount types), have different external dimensions even when their output functions are equivalent. Since the shape and size of the internal space also differ between the vertical installation type and the horizontal installation type, the sharing of components is hindered.

[0005] One aspect of the present invention provides a power supply device that can promote component sharing even when external dimensions differ depending on the model. [[Means for Solving the Problem]]

[0006] A power supply device according to one aspect of the present invention includes a housing, a first housing portion and a second housing portion that are disposed opposite each other, and a rotating plate rotatably attached to attachment portions provided on the first housing portion and the second housing portion, wherein the rotating plate is housed in the housing in at least either a first posture or a second posture. [[Effects of the Invention]]

[0007] According to the power supply device of the above aspect, component sharing can be promoted even when external dimensions differ depending on the model (e.g., vertical installation type and horizontal installation type). [Brief explanation of the drawing]

[0008] [Figure 1] This diagram partially shows an example of an uninterruptible power supply (UPS). [Figure 2] This is a diagram showing an example of the configuration of the mounting section. [Figure 3] This is a side view partially showing stationary and rack-mounted uninterruptible power supplies. [Figure 4] This diagram shows the installation status of a stationary type uninterruptible power supply (UPS). [Figure 5] This diagram shows the installation status of a rack-mount type uninterruptible power supply (UPS). [Modes for carrying out the invention]

[0009] The power supply unit comprises a housing, a first housing section and a second housing section arranged opposite each other, and a rotating plate rotatably attached to mounting sections provided on the first housing section and the second housing section, wherein the rotating plate is housed in the housing in at least one of a first or second position. The rotating plate may be rotated approximately 180° relative to the first housing section and the second housing section between the first and second positions.

[0010] Here, "revolvable" typically means being able to rotate in one direction and the opposite direction, but is not limited to this form, and in this specification, it also includes being able to rotate in only one direction. As mounting parts, the first housing part and the second housing part may each function as mounting parts, or separate parts provided in the first housing part and the second housing part (for example, a shaft body described later) may function as mounting parts. The rotating plate is housed in the housing in at least one of the first or second positions, but may be housed in the housing in other positions such as a third position, a fourth position, etc.

[0011] According to the above configuration, even if the external dimensions differ depending on the model of the power supply unit (for example, vertical or horizontal type), the structural components including the first housing section, the second housing section, the mounting section, and the rotating plate (for example, a unit assembled from these structural components) can be applied commonly and across different models. That is, in one model, the rotating plate is housed in the housing in a first position, and in other models, the rotating plate is housed in the housing in a second position. This promotes the standardization of power supply unit components.

[0012] The rotating plate comprises a component placement plate extending substantially perpendicular to the direction of rotation and a side plate extending in the direction of rotation, and the side plate may be rotatably attached to the mounting portion.

[0013] According to the above configuration, predetermined components of the power supply can be placed in the space defined by the component placement plate and the side plate. While using common structural components, depending on the model, components can be placed on the component placement plate with the rotating plate in the first position, or with the rotating plate in the second position.

[0014] The unit having the first housing portion, the second housing portion, the mounting portion, and the rotating plate may, in a side view, have the rotating plate positioned in diagonal quadrants when in the first position and when in the second position.

[0015] Here, a side view refers to the view of the side plate from a vertical direction. The axis on which the rotating plate rotates is taken as the origin, and the horizontal direction of the plane perpendicular to the axis (the plane parallel to the side plate) is assumed to be the x-axis, and the vertical direction is assumed to be the y-axis. Four quadrants (first quadrant (upper right), second quadrant (upper left), third quadrant (lower left), and fourth quadrant (lower right)) are virtually defined on this plane, separated by the x-axis and y-axis. In the above unit, for example, if the rotating plate in the first position is placed in the first quadrant, the rotating plate in the second position is placed in the third quadrant. If the rotating plate in the first position is placed in the second quadrant, the rotating plate in the second position is placed in the fourth quadrant. When the rotating plate takes each position, a part of it may extend into other quadrants.

[0016] According to the above configuration, for example, in the first posture, the dimension of the unit in the y-axis direction can be increased, and in the second posture, the dimension of the unit in the x-axis direction can be increased. Even when the external dimensions of the power supply device are different, the same unit can be applied by changing and selecting the posture of the rotating plate.

[0017] The unit including the first housing portion, the second housing portion, the mounting portion, and the rotating plate is In a side view, the rotating plate in the second posture may be arranged laterally of the first housing portion and the second housing portion.

[0018] A vertically installed power supply device is required to have a relatively large width dimension (the horizontal dimension when vertically installed) to prevent overturning. A power supply device installed horizontally in a rack or the like is required to have a height dimension (the vertical dimension when horizontally installed) that is a multiple of discretely defined specified values (e.g., 1.75 inches, 44.45 mm). When the height of the power supply device exceeds a multiple of a certain discrete value (e.g., 88 mm), a power supply installation space corresponding to the next multiple (132 mm) is required, and the installation space becomes significantly (unnecessarily) large.

[0019] According to the above configuration, by placing the rotating plate in the first posture to increase the width dimension when vertically installed, overturning of the power supply device can be prevented. Furthermore, by placing the rotating plate in the second posture and arranging it laterally of the first housing portion and the second housing portion, the height when horizontally installed can be reduced, and an unnecessary increase in size of the power supply device can be avoided.

[0020] The power supply device may further be a power supply device in which a storage battery is housed in the housing.

[0021] An uninterruptible power supply supplies backup power from a storage battery to a power load when a power abnormality such as a power outage occurs. Downsizing of the housing is required for uninterruptible power supplies that are mainly installed indoors. However, particularly in small uninterruptible power supplies (general-purpose small UPS), a large proportion of the internal space of the housing is occupied by the storage battery. According to the above configuration using the rotating plate, by changing and selecting the posture of the rotating plate so as to secure an arrangement space for the storage battery in the housing, commonization of components can be achieved, overturning during vertical installation can be prevented, and an unnecessary increase in installation space during horizontal installation can be avoided.

[0022] The rotating plate in the second posture may be arranged between the first housing portion and the second housing portion, and the storage battery.

[0023] According to the above configuration, the height of an uninterruptible power supply installed horizontally (for example, a rack-mount type uninterruptible power supply) can be reduced to the necessary minimum.

[0024] Hereinafter, embodiments of the power supply device will be described with reference to the drawings.

[0025] In this specification, "vertical installation" means a posture of the uninterruptible power supply in which the height from the lower end (for example, the installation surface) to the upper end is higher than that in "horizontal installation". "Horizontal installation" means a posture of the uninterruptible power supply in which the height from the lower end to the upper end is lower than that in "vertical installation". "Vertical direction" means a direction substantially perpendicular to the installation surface. That is, the "vertical direction" may be a direction perpendicular to the installation surface of the uninterruptible power supply, or may be a direction slightly deviated from the vertical direction but close to the vertical direction. "Horizontal direction" means a direction substantially parallel to the installation surface. That is, the "horizontal direction" may be a direction parallel to the installation surface of the uninterruptible power supply, or may be a direction slightly deviated from the parallel direction but close to the parallel direction. "Horizontal installation" includes not only the case where the uninterruptible power supply is placed on the installation surface, but also the case of rack mounting where the device is mounted on a rack or the like.

[0026] Figure 1 partially shows an example of an uninterruptible power supply (UPS) 100. The UPS unit 10 is housed in a casing (outer casing) not shown. The UPS unit 10 comprises six casing sections: a first casing section 11, a second casing section 12, a third casing section 13, a fourth casing section 14, a fifth casing section 15, and a sixth casing section 16 (see Figure 3). The first casing section 11 and the second casing section 12 are arranged facing each other, the third casing section 13 and the fourth casing section 14 are arranged facing each other, and the fifth casing section 15 and the sixth casing section 16 are arranged facing each other. Mounting sections 30 are provided on the first casing section 11 and the second casing section 12. The UPS unit 10 includes a power conversion circuit (converter and inverter).

[0027] The rotating plate 20 has a box shape and includes a component placement plate 25 (see Figure 3) extending substantially perpendicular to the direction of rotation, and a first side plate 21, a second side plate 22, a third side plate 23, and a fourth side plate 24 integrally provided around the component placement plate 25 and extending in the direction of rotation. The first side plate 21 and the second side plate 22 are arranged opposite each other, the first side plate 21 is substantially parallel to the first housing portion 11, and the second side plate 22 is substantially parallel to the second housing portion 12. The portion of the first side plate 21 that connects to the fourth side plate 24 in an L-shape (either the end of the first side plate 21 or one end of the fourth side plate 24) is rotatably attached to the mounting portion 30. An intervening object may be present between the first side plate 21 or the fourth side plate 24 and the mounting portion 30. Furthermore, the portion where the second side plate 22 connects to the fourth side plate 24 in an L-shape (either the end of the second side plate 22 or the other end of the fourth side plate) is rotatably attached to the mounting portion 30. An intervening material may be present between the second side plate 22 or the fourth side plate 24 and the mounting portion 30. As a result, the rotating plate 20 is rotatably attached to the mounting portion 30.

[0028] The rotating plate 20 accommodates (houses) predetermined components of the UPS main unit 10, including the circuit board 40.

[0029] With the above configuration, components such as a circuit board 40 can be placed in the space defined by the component placement plate 25 and the first to fourth side plates 21 to 24. As will be described later, the component placement plate 25 can support components when the rotating plate 20 is in the first position, or when the rotating plate 20 is in the second position.

[0030] Figure 2 shows an example of the configuration of the mounting portion 30. Figure 2 is an enlarged view of the portion indicated by reference numeral A in Figure 1. As shown in Figure 2, the mounting portion 30 in this embodiment includes a shaft 31 that bridges the first housing portion 11 and the second housing portion 12. One end of the shaft 31 fits into a hole 111 formed in the first housing portion 11. Although not shown, the other end of the shaft 31 fits into a hole formed in the second housing portion 12. By including the shaft 31, the mounting portion 30 allows the rotating plate 20 to rotate around a virtual axis extending along the shaft 31.

[0031] Figure 3A is a side view partially showing a desktop type uninterruptible power supply (UPS) 100, and Figure 3B is a rack-mount type. In the example in Figure 3A, the desktop type is shown horizontally (tilted 90°) instead of vertically for comparison purposes.

[0032] Assume that the origin O is the virtual axis around which the rotating plate 20 rotates, and assume that the horizontal direction of the plane perpendicular to the virtual axis O is the x-axis, and the vertical direction is the y-axis. Four quadrants are virtually defined on this plane, separated by the x-axis and y-axis: the first quadrant (upper right), the second quadrant (upper left), the third quadrant (lower left), and the fourth quadrant (lower right).

[0033] In the stationary type shown in Figure 3A, the rotating plate 20 is positioned above (to the side when vertically oriented) the mounting portions of the first housing portion 11 and the second housing portion 12. This state is referred to as the first orientation of the rotating plate 20. The rotating plate 20 in the first orientation is positioned in the second quadrant. The first component mounting surface 41 of the circuit board 40 mounted on the rotating plate 20 faces upward. The circuit board 40 may be capable of double-sided mounting.

[0034] In the rack-mount type shown in Figure 3B, the rotating plate 20 is positioned to the side of the mounting portions of the first housing section 11 and the second housing section 12. This state is referred to as the second position of the rotating plate 20. In the second position, the rotating plate 20 is positioned in the fourth quadrant. The first component mounting surface 41 of the circuit board 40 placed on the rotating plate 20 faces downward. The rotating plate 20 rotates approximately 180° relative to the first housing section 11 and the second housing section 12 between the first and second positions. Both the desktop and rack-mount types have a rectangular parallelepiped housing. By employing a rotating plate 20 that rotates approximately 180°, it fits well into either type of housing and does not interfere with the placement of other components.

[0035] When viewing the stationary and rack-mount types shown in Figure 3 from the opposite side, the rotating plate 20 in the first orientation is located in the first quadrant, and the rotating plate 20 in the second orientation is located in the third quadrant. The circuit board 40 placed on the rotating plate 20 is located in diagonal quadrants in a side view, depending on whether it is in the first or second orientation.

[0036] The rotating plate 20 is configured to rotate around the mounting portion 30 so as to move from a first position to a second position, or so as to move from a second position to a first position.

[0037] The same circuit board 40 may be used for both the desktop type and the rack-mount type. This allows for the common use of components, including the circuit board 40, in different models, for the unit having the first housing section 11, the second housing section 12, the mounting section 30, and the rotating plate 20.

[0038] According to the above configuration, when the rotating plate 20 is in the first position, the y-axis dimension of the UPS body 10 can be increased, and when the rotating plate 20 is in the second position, the x-axis dimension of the UPS body 10 can be increased. Even if the external dimensions differ depending on the model of the uninterruptible power supply 100 (for example, vertical or horizontal type), the same unit can be applied by changing and selecting the position of the rotating plate 20.

[0039] In the rack-mount type shown in Figure 3B, the rotating plate 20 in the second orientation is positioned to the side of the first housing section 11 (and the second housing section 12). The battery 50 of the uninterruptible power supply 100 is positioned to the side of the rotating plate 20 in the second orientation. In other words, the rotating plate 20 is positioned between the first housing section 11 (and the second housing section 12) and the battery 50. The top surfaces of the first housing section 11 (and the second housing section 12), the rotating plate 20, and the battery 50 are almost flush. This configuration allows the UPS unit 10 to be made to the minimum necessary height to match the height of the battery 50.

[0040] Figure 4 shows the UPS unit 10 and battery 50 in the installed state of a stationary type uninterruptible power supply (UPS) 100. In the stationary type (vertical type), the width dimension (horizontal dimension when vertically placed, indicated by the symbol W in Figure 4) needs to be relatively large to prevent the UPS 100 from tipping over. Also, the height dimension (indicated by the symbol H in Figure 4) should preferably be relatively small to prevent tipping over. The UPS 100 has a relatively heavy battery 50 mounted on its lower side.

[0041] Figure 5 shows the UPS unit 10 in the installed state of a rack-mount type uninterruptible power supply 100. In the rack-mount type, the height dimension (vertical dimension when placed horizontally, indicated by the symbol H in Figure 5) must be a multiple of a discretely defined specified value in order to be installed in a rack. If the height dimension exceeds a multiple of a certain discrete value, the power supply installation space corresponding to the next multiple will be required, resulting in a significantly (unnecessarily) large installation space. On the other hand, in the rack-mount type, the length dimension (indicated by the symbol L in Figure 5) can be larger than the height dimension H. Therefore, the battery 50 is arranged along the length direction.

[0042] In this embodiment, the width dimension W (see Figure 4) of the UPS unit 10 when placed vertically and the height dimension H (see Figure 5) when placed horizontally are different. As shown in Figure 1, one end of the first side plate 21 and the second side plate 22 (or fourth side plate 24) of the rotating plate 20 is rotatably attached to the mounting part 30, thereby enabling it to assume these diagonal first and second positions.

[0043] In the above embodiment, an example of applying the present invention to an uninterruptible power supply 100 was described, but the present invention can also be applied to other power supply devices that incorporate a power conversion circuit (converter and / or inverter). That is, the present invention can also be applied to power supply devices such as power conditioners, DC power supply devices, and electric vehicle power conditioners (EVPS). The present invention may be applied across different types of power supply devices with different functions. [Explanation of symbols]
