The accompanying drawings in the specification illustrate examples of embodiments of the utility model, wherein the same reference numerals represent the same elements. It is understood that the scales shown in the accompanying drawings in the specification are not the scales of the actual implementation of the utility model, which are only for the purpose of illustration and are not drawn according to the original size.

[0035] Please see Figure 1 and Figure 2 , Figure 1 An exploded view of a UPS power supply chassis provided in an embodiment of the utility model, Figure 2 A three-dimensional diagram of a UPS power case provided in an embodiment of the utility model. The present application provides a UPS power case 10, which can realize the reuse of a plurality of different types of transformers 3 by a UPS power case 10, thereby reducing the cost of different types of cases produced to adapt to different types of transformers 3. The specific features of the UPS power case 10 will be described in detail below in conjunction with the accompanying drawings.

[0036] like Figure 1 and Figure 2 As shown, the UPS power supply chassis 10 includes a first cover body 1 and a second cover body 2. The first cover body 1 and the second cover body 2 can be relatively covered. When the first cover body 1 and the second cover body 2 are relatively covered, a cavity for accommodating the transformer 3 is formed (not shown). In the present application, the cavity is also used to accommodate other components of the UPS power supply, such as a rectifier, a battery, an inverter, etc. The components of the UPS power supply are located outside the installation path when the transformer 3 is installed in the cavity, so as to avoid different types of transformers being restricted by other components of the UPS power supply when installed on the transformer 3.

[0037] In this embodiment, the UPS power supply chassis 10 also includes a plurality of first mounting parts. The plurality of first mounting parts are arranged on one end surface of the first cover body 1 facing the second cover body 2. The first mounting parts are arranged according to transformers 3 of different sizes to form a plurality of first assembly components. Specifically, each first assembly component includes a plurality of first mounting parts. The size of the transformer 3 includes but is not limited to the length, width, height, etc. of the transformer 3. In each first assembly component, the plurality of first mounting parts are arranged on the first cover body 1 in correspondence with the sizes of the transformers 3 and the structures in which the transformers 3 are installed to form a plurality of first assembly components, so that the plurality of first mounting parts of each first assembly component are adapted to install a transformer 3 of one size.

[0038] like Figure 3 and Figure 4 As shown, the first mounting member may be a screw column 31. A plurality of mounting holes 33 are provided on one end surface of the transformer 3 facing the first cover body 1. The plurality of mounting holes 33 are provided on the transformer 3 corresponding to the first mounting member. Each mounting hole 33 corresponds to each screw column 31 in each first assembly component, and each mounting hole 33 cooperates with the corresponding screw column 31 to install the transformer 3 in the cavity. The cooperation mode of the screw column 31 and the mounting hole 33 includes but is not limited to thread cooperation, the screw column 31 is fixed to the mounting hole 33 in combination with a screw, etc.

[0039] For example, the first mounting member is a screw column 31. The number of screw columns 31 is four. When transformers 3 of various sizes such as 76.2mm*63.5mm*28mm, 76.2mm*63.5mm*35mm, 76.2mm*63.5mm*44mm, 76.2mm*63.5mm*50mm need to be installed in the cavity, the screw columns 31 can be arranged on the first cover body 1 at a spacing of 64mm*50.8mm according to the various sizes of the transformer 3 and the arrangement position of the mounting holes 33 on the transformer 3, thereby achieving the installation of the transformer 3 and adapting to the transformer 3 of the same size.

[0040] Furthermore, in order to ensure that each screw column 31 can be stably matched with the corresponding mounting hole 33, a stopper 35 is provided on the outer wall of each screw column 31. The shape of each stopper 35 is adapted to the corresponding mounting hole 33. Each stopper 35 is matched with the mounting hole 33 corresponding to each screw column 31, so that each screw column 31 is fixed to the corresponding mounting hole 33 through the stopper 35 after being matched with the corresponding mounting hole 33, thereby ensuring that the transformer 3 is stably mounted in the cavity.

[0041] In this embodiment, in order to ensure that transformers 3 of different sizes can be stably installed by corresponding assembly components, transformers 3 of different sizes are further fixed to the cavity by providing corresponding limiters on the outer wall of the first mounting member. For example, the outer wall of each screw column 31 is also provided with a first limiter 37, so that when the transformer 3 is installed in the cavity through multiple screw columns 31, the first limiter 37 is deformed by the action of the transformer 3, thereby fixing the transformer 3 to the cavity. Among them, the first limiter 37 can be an elastic bone structure. The number of bone structures corresponding to each screw column 31 is one or more. Part or all of the bone structures are deformed when affected by the transformer 3, so as to position the transformer 3 in the cavity and limit the transformer 3.

[0042] In this embodiment, the installation of transformers 3 of different sizes can also be achieved by using different types of mounting parts. Specifically, the UPS power supply chassis 10 also includes a plurality of second mounting parts. The plurality of second mounting parts are arranged on the opposite end surfaces of the first cover body 1 and the second cover body 2 and correspond one to one. The second mounting parts are arranged according to transformers 3 of different sizes to form a plurality of second assembly components. Each second assembly component includes a plurality of groups of corresponding second mounting parts, and the plurality of groups of corresponding second mounting parts of each second assembly component are adapted to install a transformer 3 of one size.

[0043] Furthermore, each first mounting member in each first assembly component and each group of second mounting members in each second assembly component have a certain distance. The size of the transformer 3 adapted to be installed by the plurality of first mounting members is not equal to the size of the transformer 3 adapted to be installed by the plurality of corresponding groups of second mounting members, so as to further realize the installation of transformers 3 of different sizes by using different types of mounting members.

[0044] It should be understood that when transformers 3 of different sizes are installed in the cavity through a first assembly component formed by a plurality of first mounting parts or a second assembly component formed by a plurality of groups of corresponding second mounting parts, the plurality of first mounting parts and the plurality of groups of corresponding second mounting parts are located outside the installation path of the transformer 3, so as to realize that the transformer 3 is not affected by other mounting parts that are not involved in the installation of the transformer 3 when it is installed in the cavity, on the basis of realizing the adaptation and installation of a UPS power supply chassis 10 for transformers 3 of various sizes. Therefore, according to transformers 3 of more sizes, more types of mounting parts can be set at the positions of the first cover body 1 and / or the second cover body 2 corresponding to the accommodating transformer 3 in combination with the cavity to adapt and install transformers 3 of more sizes. Among them, there is a certain distance between different types of mounting parts. The first mounting part and the second mounting part are respectively adapted to correspond to any two of the above-mentioned multiple different sizes of mounting parts. The use of two types of mounting parts in the present application is not limited to the installation of two types of transformers 3 of different sizes. The use of multiple types of mounting parts to install multiple types of transformers 3 of different sizes is also within the scope of protection of the present application. It is only necessary to ensure that when the transformer 3 is installed in the cavity through any mounting part, each mounting part that does not participate in the installation of the transformer 3 is located outside the installation path of the transformer 3.

[0045] like Figure 5 As shown, the second mounting member can be a plug-in column 32. The transformer is provided with a plurality of plug-in through holes 34 from one end surface facing the first cover body 1 to one end surface facing the second cover body 2. Each plug-in through hole 34 corresponds to each group of corresponding plug-in columns 32 in each second assembly component. Each plug-in through hole 34 cooperates with the corresponding group of corresponding plug-in columns 32 to install the transformer 3 in the cavity.

[0046] For example, the second mounting member is a plug-in column 32. The plug-in column 32 is arranged on the two opposite end surfaces of the first cover body 1 and the second cover body 2. The number of the plug-in columns 32 on the first cover body 1 and the second cover body 2 is four respectively, forming four groups of corresponding plug-in columns 32. When transformers 3 of various sizes such as 86mm*71.5mm*50mm, 86mm*71.5mm*52mm, etc. need to be installed in the cavity, four groups of corresponding plug-in columns 32 can be arranged on the two opposite end surfaces of the first cover body 1 and the second cover body 2 at a spacing of 71mm*57.2mm according to the various sizes of transformers 3 and the layout position of the mounting holes 33 on the transformer 3, thereby realizing the installation of the transformer 3 and adapting to transformers 3 of the same size.

[0047] Furthermore, the outer wall of each plug-in column 32 is provided with a fixing structure 36, so as to fix the plug-in column 32 to the first cover 1 and the second cover 2 through the fixing structure 36. The outer wall of each plug-in column 32 forms a guide angle with the corresponding fixing structure 36, so that the transformer 3 is installed in the cavity according to the guide angle.

[0048] It can be understood that in the present application, the transformer 3 may be provided with only one of the mounting hole 33 and the plug-in through hole 34, or may be provided with both the mounting hole 33 and the plug-in through hole 34. When the transformer 3 is provided with both the mounting hole 33 and the plug-in through hole 34, the mounting hole 33 and the plug-in through hole 34 are also arranged at a certain distance in the layout position of the transformer 3, and correspond to the layout positions of the plurality of first mounting parts and the plurality of second mounting parts, respectively, so that the transformer 3 can be installed in the cavity without being affected by the mounting parts that are not involved in the installation of the transformer 3, thereby realizing the selective installation of transformers 3 of different models in one UPS power supply chassis 10 to complete the reuse of the UPS power supply chassis 10.

[0049] Similarly, transformers 3 of different sizes are further fixed to the cavity by providing corresponding limiters on the outer wall of the second mounting member. For example, the outer wall of each plug-in column 32 is also provided with a second limiter 38, so that when the transformer 3 is installed in the cavity through multiple plug-in columns 32, the second limiter 38 is deformed by the action of the transformer 3, thereby fixing the transformer 3 in the cavity. Among them, the second limiter 37 can be an elastic bone structure. The number of bone structures corresponding to each plug-in column 32 is one or more. Part or all of the bone structures are deformed when affected by the transformer 3, so as to position the transformer 3 in the cavity and limit the transformer 3.

[0050] Please see Figure 6 , which is a schematic diagram of the structure of a UPS power supply provided in an embodiment of the utility model. The embodiment of the utility model also provides a UPS power supply 100. The UPS power supply 100 includes a UPS power supply chassis 10. The UPS power supply chassis 10 is used to accommodate a transformer 3 of a first size or a transformer 3 of a second size. The specific features of the UPS power supply chassis 10 have been described in detail in the previous text and will not be repeated here.

[0051] In the above embodiment, according to transformers of different sizes, a plurality of first mounting parts are provided on one end surface of the first cover body facing the second cover body to form a plurality of first assembly components, so that the plurality of assembly components corresponding to the first mounting parts can be adapted to install transformers of different sizes. At the same time, according to transformers of different sizes, a plurality of second mounting parts are provided on the opposite end surfaces of the first cover body and the second cover body to form a plurality of second assembly components, so that the plurality of assembly components corresponding to the second mounting parts can be adapted to install transformers of different sizes, thereby realizing the reuse of transformers of different models by the UPS power supply chassis, thereby reducing the manufacturing cost of the UPS power supply chassis.

[0052] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0053] The above examples are only preferred embodiments of the present invention, and certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
