[0026] Now, with reference to the accompanying drawings, the schematic scheme of the uninterruptible power module and the handle assembly thereof disclosed by the utility model is described in detail. Although the accompanying drawings are provided to present some embodiments of the utility model, the accompanying drawings do not have to be drawn according to the dimensions of the specific implementation scheme, and certain features may be enlarged, removed or partially cut away to better illustrate and explain the disclosure of the utility model. Some components in the accompanying drawings can be adjusted in position according to actual needs without affecting the technical effect. The phrase "in the accompanying drawings" or similar terms appearing in the specification do not necessarily refer to all drawings or examples.

[0027] Certain directional terms used to describe the drawings below, such as "inside", "outside", "above", "below" and other directional terms, will be understood to have their normal meanings and refer to those directions involved when the drawings are normally viewed. Unless otherwise specified, the directional terms described in this specification are basically in accordance with the conventional directions understood by those skilled in the art.

[0028] The terms "first", "first", "second", "second" and the like used in the present invention do not indicate any order, quantity or importance, but are used to distinguish one component from other components.

[0029] The utility model provides a modular uninterruptible power module (UPM), such as Figure 1 As shown, the uninterruptible power module 1 is constructed into a rectifier module 2, an inverter module 3 and a fan module 4 according to functions and regions. The modules are detachably connected. In this way, when installing the uninterruptible power module in the UPS system cabinet or removing the uninterruptible power module from the UPS system cabinet, each module can be operated one by one, which usually only requires one person to complete. In this article, "detachable" means that the connected components can be separated from each other, and the separated components still have the same configuration and function as the initial state before connection, and the configuration and function will not be damaged due to the separate operation. Figure 2 The uninterruptible power module 1 in a disassembled state is schematically shown, wherein the fan module 5 has been removed as a whole, and the inverter module 3 is being disassembled as a whole from the rectifier module 2 .

[0030] like Figure 1As shown, the rectifier module 2 includes a first housing 21 and a first electrical network 22 mounted to the first housing 21, or can be called a first circuit. The first electrical network 22 is configured to selectively connect to a main power supply or a backup power supply through an input port provided in the first housing 21, and convert the current provided by the main power supply or the current provided by the backup power supply into a direct current (DC). The main power supply can be, for example, a three-phase AC power supply, such as a mains power supply, and the backup power supply can be, for example, a DC battery. All components of the first electrical network 22 are mounted in the first housing 21. The first housing 21 includes a bottom wall 212, two side walls 211 provided at opposite ends of the bottom wall 212, and an end wall connected between the bottom wall 212 and the two side walls 211. The first housing 21 of the rectifier module 2 is also a part of the housing of the entire uninterruptible power module 1. In view of the fact that in the illustrated embodiment, the rectifier module 2 is located vertically below the inverter module 3, the bottom wall 212 of the rectifier module 2 also serves as the bottom wall of the housing of the entire UPM.

[0031] The inverter module 3 includes a second housing 31 and a second electrical network 32 installed in the second housing 31, or can be called a second circuit. The second electrical network 32 is configured to be connected to the first electrical network 22 and convert DC into AC, and provide AC electric power to the load through the output port installed in the second housing 31. All components of the second electrical network 32 are installed in the second housing 31. The second housing 31 includes a top wall 312, two side walls 311 arranged at opposite ends of the top wall 312, and an end wall connected between the top wall 312 and the two side walls 311. The second housing 31 of the inverter module 3 is also part of the outer shell of the entire uninterruptible power module 1. In view of the fact that in the illustrated embodiment, the inverter module 3 is located vertically above the rectifier module 2, the top wall 312 of the inverter module 3 also serves as the top wall of the outer shell of the entire UPM.

[0032] According to the illustrated embodiment, in the assembled uninterruptible power module 1, the inverter module 3 and the rectifier module 2 are stacked vertically, wherein the side wall 311 of the second housing 31 is vertically opposite to the side wall 211 of the first housing 21 and together constitutes the side wall of the entire UPM housing, and the end wall of the second housing 31 is vertically opposite to the end wall of the first housing 21 and together constitutes the rear end wall of the entire UPM housing. The fan module 4 can be connected to the first housing 21 and the second housing 31 from the front side, thereby constituting the front end wall of the entire UPM housing.

[0033] The handle assembly 5 can be installed on the second housing 31 located above, for example, installed on the side wall 311 of the second housing 31. An opening can be formed at the position of the side wall 311 where the handle assembly 5 is expected to be installed, and the size is adapted to the size of the handle assembly 5. Figure 3 and Figure 4An example of a handle assembly 5 is specifically shown. As shown in the figure, the back plate 6 of the handle assembly 5 can be installed at the opening of the side wall 311 from the inside, and the back plate 6 itself constructs a receiving groove 61 for receiving the handle 7, and the receiving groove 61 is open to the outside of the second shell 31. The receiving groove 61 can be formed by integrally bending the periphery of the back plate 6. The figure shows that the back plate 6 has four sides along the circumference, including two sides opposite to each other in a first direction, such as vertically, and two sides opposite to each other in a second direction perpendicular to the first direction, such as horizontally. The two sides opposite to each other in the first direction are bent respectively, thereby forming a first bending portion 62 and a second bending portion 63, wherein the first bending portion 62 and the second bending portion 63 are respectively provided with mounting holes 621, 631, which are used to be connected to the side wall 311 of the second shell 31 by a connecting member such as a bolt or a screw. Similarly, two side edges opposite to each other in the second direction are bent respectively to form a third bent portion 64 and a fourth bent portion 65, wherein the third bent portion 64 and the fourth bent portion 65 respectively have mounting holes 641 and 651 for connecting to the side wall 311 of the second housing 31 through connecting members such as bolts or screws. In this way, the first bent portion 62, the second bent portion 63, the third bent portion 64 and the fourth bent portion 65 together constitute the groove wall of the accommodating groove 61. An orifice 632 may also be formed in the second bent portion 63.

[0034] The shape of the back plate can be modified in addition to the quadrilateral shown in the figure. For example, the back plate can be assembled as a whole with one side being a straight side and the other side being a curved side, and the straight side and the curved side are bent respectively, so that the curved installation groove wall is constructed at the bent part of the curved side, so as to adapt to the round or oval handle grip.

[0035] Since the back panel 6 is mounted to the side panel 311 of the second shell 31 from the inside, the receiving groove 61 is equivalent to being recessed from the side panel 311, thereby providing space for storing the handle 7. The handle 7 is pivotally arranged in the receiving groove 61, and the groove wall of the receiving groove 61 constrains the movement of the handle 7 along the pivot axis. The handle 7 exists in two states, namely, the storage state and the use state. In the storage state, the handle 7 can be completely embedded in the receiving groove 61, so the side panel 311 is flatter from the surface, which is conducive to inserting the UPM into the system cabinet, and the size of the system cabinet does not need to be adjusted for the existence of the handle. In the use state, the handle 7 can be rotated and extended from the receiving groove 61 for easy operation.

[0036] In this embodiment, the handle 7 is constructed to include a grip portion 71 and two pivot shafts 72 connected to opposite ends of the grip portion 71. The two pivot shafts 72 extend away from each other in the second direction, and their central axes coincide with each other, serving as the pivot axis of the handle 7. Each pivot shaft 72 extends through the corresponding third bending portion 64 or fourth bending portion 65 along the second direction, and for this purpose, the third bending portion 64 and the fourth bending portion 65 have a preset opening 66 for the pivot shaft 72 to pass through. The opening 66 can be realized by various means, for example, it can be formed by an orifice formed on the third bending portion 64 and the fourth bending portion 65. Alternatively, in the illustrated embodiment, the opening 66 is formed at the interval by spacing the third bending portion 64 from the adjacent first bending portion 62 and spacing the fourth bending portion 65 from the adjacent first bending portion 62.

[0037] The portion of the pivot shaft 72 extending out of the receiving groove 61 can be embedded in the mounting member 9. Corresponding to the pivot shafts 72 on opposite sides of the gripping portion 71, a mounting member 9 is provided on the outer side of the third bending portion 64 and the fourth bending portion 65 of the back plate 6, corresponding to the position of the opening 66, wherein each mounting member 9 is connected to the side plate 311 of the second housing 31. The mounting member 9, as a mounting base for the pivot shaft 72, can be provided with a mounting groove 94 for inserting the pivot shaft 72, and the mounting groove 94 is open toward the corresponding opening 66. Mounting holes 92 are formed at opposite ends of the mounting groove 94, respectively, so as to connect the mounting member 9 to the side plate 311 of the second housing 31 through a connecting member such as a bolt or a screw. The mounting member 9 can be formed by integrally bending a plate member, for example, the plate member can be bent to form an arcuate wall 91, and the mounting groove 94 is defined by the arcuate wall 91 to adapt to the outer peripheral contour of the pivot shaft 72.

[0038] In the illustrated embodiment, a damping sleeve 8 is also sleeved on the pivot shaft 72 of the handle 7. The damping sleeve 8 can be made of an elastic material, such as rubber or silicone. The inner circumference of the damping sleeve 8 is adapted to the outer circumference of the pivot shaft 72 of the handle 7, and the outer circumference of the damping sleeve 8 is adapted to the inner circumference of the mounting groove 94 of the mounting member 9. In this way, the gap between the pivot shaft 72 of the handle 7 and the mounting groove 94 is filled by the damping sleeve 8, and the damping sleeve 8 provides friction to prevent the handle 7 from moving. In order to limit the axial movement of the damping sleeve 8 and the handle 7, a stop wall 93 can be provided on the side of the mounting member 9 facing away from the opening 66.

[0039] Although the figure shows the handle 7 with two sections of the pivot shaft 72 on opposite sides of the grip portion 71, those skilled in the art will understand that the two sections of the pivot shaft 72 can be combined, that is, a long pivot shaft extends from opposite ends of the grip portion 72 and is inserted into the mounting groove 94 of the mounting member 9, which can also achieve the same effect as the illustrated embodiment.

[0040] Combine the following Figure 1 and Figure 2 The following describes how the uninterruptible power module 1 according to the present invention is removed from the system cabinet one by one in modules. As mentioned above, this modular uninterruptible power module 1 is particularly advantageous in this case because the operator does not need to bear the weight of the entire uninterruptible power module 1 weighing several tens of kilograms.

[0041] First, the uninterruptible power module 1 is extracted from the system cabinet in a substantially horizontal direction, but need not be entirely removed. During this extraction process, the weight of the uninterruptible power module 1 is almost entirely borne by the system cabinet.

[0042] Remove fan module 4 from the front.

[0043] Remove a small amount of cabling from the front end of the uninterruptible power module 1.

[0044] Remove the connecting piece between the first shell 21 and the second shell 31 .

[0045] The handle 7 is turned to extend from the mounting groove 94, and the inverter module 3 located above is pulled out by the handle to remove the inverter module 3 from the system cabinet. In the case where a guide sliding structure is provided between the first housing 21 of the rectifier module 2 and the second housing 31 of the inverter module 3, this pulling out action will be more labor-saving.

[0046] Pull out the remaining rectifier module 2 and remove the rectifier module 2 from the system cabinet.

[0047] The entire process of removing the uninterruptible power module 1 can be completed by one operator. The uninterruptible power module 1 is installed in the system cabinet in the same way, and can be installed one by one in the module area.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
