[0023] The above drawings have shown the specific embodiments of the application, and the following will have more detailed description. These drawings and textual descriptions are not intended to limit the scope of the concept of the application by any means, but to illustrate the concept of the application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0024] ​​​The exemplary embodiments will be described in detail herein with reference to the attached drawings. The following description is made with reference to the accompanying drawings in which like reference numerals designate identical or similar elements in the several figures. The implementations described in the following exemplary embodiments are not meant to represent all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the appended claims.

[0025] Firstly, the terms involved in the present application are explained:

[0026] Body structure: refers to the shell structure of the outer surface of the power distribution unit.

[0027] Identification structure: refers to the structure on the power distribution unit or power distribution device corresponding to the position of the power outlet, which is used to indicate the position information of the power outlet.

[0028] Cabinet: refers to a special device for storing and organizing computing devices, network devices and other information technology devices.

[0029] With the rapid development of science and technology, the process of informatization is gradually accelerated. The transmission and processing of various data and information need to be completed through electronic devices. For example, a personal computer server (PC server for short) can be used for file service, database service, mail service, etc. of a personal computer; a switch can be used to connect multiple electronic devices so that multiple electronic devices can exchange data in a local area network. These electronic devices as carriers of data and information are usually placed in cabinets and need to be powered independently. The size of the cabinet can be measured by U. Through U, users can accurately plan and arrange the installation position of electronic devices in the cabinet, so as to ensure enough space between devices.

[0030] In some embodiments, the power distribution unit (PDU for short) is used to power various electronic devices in the cabinet. When various electronic devices are installed in the cabinet, these various electronic devices in the cabinet are used as power equipment. The power line of the power equipment is connected with the power outlet on the PDU to realize power supply.

[0031] In the above embodiments, the power outlet on the PDU has no identification capable of reflecting its position information.

[0032] In a possible application scenario, when the electrical equipment is installed in the cabinet, the power line of the electrical equipment is connected with the power outlet on the PDU, so as to realize power supply for the electrical equipment. In this process, the power outlet on the PDU has no identification capable of indicating the position information. Therefore, in the installation process of the electrical equipment, the correspondence between the electrical equipment and the power outlet on the PDU is unclear.

[0033] In another possible application scenario, in daily operation and maintenance, the electrical equipment in the cabinet may need to be disassembled and debugged, or the installation position of the electrical equipment in the cabinet needs to be adjusted. Before the electrical equipment is disassembled and debugged or the position is adjusted, the electrical equipment needs to be powered off. Because the number of electrical equipment in the cabinet is large, and there is no identification on the PDU, the correspondence between the electrical equipment and the power outlet on the PDU is unclear, and misoperation is likely to occur. For example, the power line of other electrical equipment is pulled out, causing equipment failure and other abnormal conditions. Therefore, when there is no identification on the power outlet on the PDU, the maintenance efficiency of the electrical equipment is low.

[0034] In combination with the above scenarios, it can be known that in the prior art, the correspondence between the electrical equipment and the power outlet on the power distribution device is unclear, which is not conducive to the installation of the electrical equipment and the maintenance of the electrical equipment.

[0035] The power distribution unit, the power distribution device and the cabinet provided in the application are provided with the identification structure corresponding to the plurality of power outlets on the body structure of the power distribution unit, so as to clearly indicate the position information of the power outlet on the power distribution unit, so that when the electrical equipment in the cabinet is connected with the power distribution unit, the connection relationship between the power line of the electrical equipment and the power distribution unit can be clearly indicated. Further, based on the clear connection relationship, the efficiency in the installation and maintenance process of the electrical equipment can be improved.

[0036] The technical solutions of the application and how the technical solutions of the application solve the above technical problems will be described in detail in the specific embodiments below. The specific embodiments below can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the application will be described below with reference to the drawings.

[0037] Figure 1 The structural schematic diagram of the power distribution unit provided in the application is shown in FIG. 1. Figure 1 As shown in the figure, the power distribution unit 1 comprises a body structure 11, a plurality of power outlets 12 are arranged on the body structure 11, and the surface of the body structure 11 is provided with an identification structure 13 corresponding to the power outlet 12.

[0038] The body structure is provided with a power input end (not shown in the figure) connected with the main power supply, and the power outlet 12 is used to be connected with the electrical equipment in the cabinet.

[0039] The body structure 11 of the power distribution unit 1 is the outer shell of the power distribution unit. The specific shape of the body structure 11 is not limited, and can be a cuboid, a rounded cuboid, etc. A plurality of power outlets 12 are arranged on the body structure 11, and the specific number of the power outlets 12 is not limited and can be determined according to actual conditions. The power input end is connected to the main power supply, and can also be connected to a bus bar, which is connected to each power outlet on the power distribution unit (PDU) to enable each power outlet to supply power to the electrical equipment.

[0040] For example, an identification structure 13 corresponding to each power outlet is arranged on one side of the power outlet. The identification structure 13 is used to indicate the position information of the power outlet corresponding thereto. For example, in the process of installing electrical equipment in the cabinet, the installation position of the electrical equipment is determined by the U position in the cabinet. The identification information of the identification structure 13 on the PDU can correspond to the U position in the cabinet.

[0041] Figure 2 An example of a front view of a cabinet U position. Figure 2 A cabinet U position setting is shown, and 24 U positions are arranged on both sides of the cabinet. This example of the cabinet is used to explain the identification structure on the PDU provided by the present application, and the two U positions on the cabinet can correspond to one identification structure on the PDU.

[0042] For example, the identification information of the identification structure can have different setting modes. For example, as shown in the PDU, the identification information of the identification structure of the example PDU is set to the lower position. The lower position refers to the identification information on the identification structure of the PDU, which records the position information corresponding to the lower U position of the two U positions on the cabinet. Figure 1

[0043] ​In one example, if the electrical equipment occupies one U position in the cabinet, the position of the electrical equipment in the cabinet can be recorded as [XU]. Wherein, X is a positive integer. It should be noted that for the electrical equipment occupying one U position, when installed in the cabinet, it is still considered as a group of two U positions. If X is an odd number, the power cord of the electrical equipment can be inserted into the power socket corresponding to the identification information [XU] on the identification structure. For example, if a switch is installed in the cabinet [3U, 4U] [3U], the power cord of the switch can be inserted into the power socket corresponding to the identification information [3U] on the identification structure. If X is an even number, the power cord of the electrical equipment can be inserted into the power socket corresponding to the identification information [(X-1)U] on the identification structure. For example, if a switch is installed in the cabinet [7U, 8U] [8U], the power cord of the switch can be inserted into the power socket corresponding to the identification information [7U] on the identification structure.

[0044] In another example, if the electrical equipment occupies two U positions in the cabinet, the position of the electrical equipment in the cabinet can be recorded as [XU, (X+1)U]. Wherein, X is an odd number greater than 0. The power cord of the electrical equipment can be inserted into the power socket corresponding to the identification information [XU] on the identification structure. For example, if a switch is installed in the cabinet [3U, 4U], the power cord of the switch can be inserted into the power socket corresponding to the identification information [3U] on the identification structure.

[0045] In another example, if the electrical equipment occupies two U positions in the cabinet, the position of the electrical equipment in the cabinet can be recorded as [XU, (X+1)U]. Wherein, X is an odd number greater than 0. The power cord of the electrical equipment can be inserted into the power socket corresponding to the identification information [XU] on the identification structure. For example, if a switch is installed in the cabinet [3U, 4U], the power cord of the switch can be inserted into the power socket corresponding to the identification information [3U] on the identification structure.

[0046] For example, the identification information of the identification structure can also be set to take the upper position. Figure 3 The structure of the power distribution unit provided in the present application Figure 2 As shown in the PDU shown in Figure 3 The identification information of the identification structure of the exemplary PDU is set to take the upper position. The upper position refers to the identification information on the identification structure of the PDU, which records the position information corresponding to the upper U position of the two U positions on the cabinet.

[0047] In one example, if the electrical equipment occupies one U position in the cabinet, the position of the electrical equipment in the cabinet can be recorded as [XU]. Wherein, X is a positive integer. It should be noted that for the electrical equipment occupying one U position, when installed in the cabinet, it is still considered as a group of two U positions. If X is an odd number, the power cord of the electrical equipment can be inserted into the power socket corresponding to the identification information [ (X+1) U] on the identification structure. For example, if a switch is installed in the cabinet at [23U, 24U] of [23U], the power cord of the switch can be inserted into the power socket corresponding to the identification information [24U] on the identification structure. If X is an even number, the power cord of the electrical equipment can be inserted into the power socket corresponding to the identification information [XU] on the identification structure. For example, if a switch is installed in the cabinet at [23U, 24U] of [24U], the power cord of the switch can be inserted into the power socket corresponding to the identification information [24U] on the identification structure.

[0048] In another example, if the electrical equipment occupies two U positions in the cabinet, the position of the electrical equipment in the cabinet can be recorded as [XU, (X+1) U]. Wherein, X is an odd number greater than 0. The power cord of the electrical equipment can be inserted into the power socket corresponding to the identification information [XU] on the identification structure. For example, if a switch is installed in the cabinet at [3U, 4U], the power cord of the switch can be inserted into the power socket corresponding to the identification information [4U] on the identification structure.

[0049] In another example, if the electrical equipment occupies two U positions in the cabinet, the position of the electrical equipment in the cabinet can be recorded as [XU, (X+1) U]. Wherein, X is an odd number greater than 0. The power cord of the electrical equipment can be inserted into the power socket corresponding to the identification information [XU] on the identification structure. For example, if a switch is installed in the cabinet at [3U, 4U], the power cord of the switch can be inserted into the power socket corresponding to the identification information [4U] on the identification structure.

[0050] The power distribution unit provided by the embodiments of the present application is provided with a plurality of power sockets on the body structure of the power distribution unit, and is provided with an identification structure corresponding to each of the plurality of power sockets on the surface of the body structure; the body structure is further provided with a power input end connected with a main power supply, and the power sockets on the body structure are used to be connected with the electrical equipment in the cabinet to supply power to the electrical equipment. The identification structure corresponding to the power socket on the power distribution unit is used to indicate the position information of the power socket connected with the current electrical equipment, so that the installation position of the electrical equipment in the cabinet is clearly corresponding to the position of the power socket of the electrical equipment on the power distribution unit, and the efficiency of installing the electrical equipment in the cabinet and maintaining the electrical equipment in the later period is improved.

[0051] On the basis of the above-mentioned embodiments, the identification structure of the power distribution unit is a laser etching structure; or the identification structure of the power distribution unit is a smearing layer.

[0052] Exemplarily, the manner of setting the structure identification on the surface of the PDU can include but is not limited to laser etching, ink printing, engraving, etc.

[0053] In an example, the identification structure of the PDU is a laser etching structure. A small-power laser with high beam quality is focused on a very small light spot to make the material evaporate instantaneously, so as to form the laser etching structure on the surface of the body structure of the PDU. It can be understood that the laser etching structure formed on the surface of the body structure by the laser can include but is not limited to a hole, a groove, a notch, etc.

[0054] In another example, the identification structure of the PDU is a smearing layer. An ink is used to form the smearing layer on the surface of the body structure of the PDU. The specific selection of the ink is not limited in the embodiment. The ink with low viscosity, strong adhesion, strong chemical corrosion resistance and good wear resistance can be selected. For example, ultraviolet curing ink (UV ink) or electron beam ink (EB ink).

[0055] In the above-mentioned embodiments, the identification structure can be set on the body structure of the power distribution unit in various ways, and the identification information indicated by the identification structure can clearly reflect the installation position of the electrical equipment in the cabinet and the corresponding relationship between the electrical equipment and the power socket on the power distribution unit.

[0056] In a possible application case, the setting manner of the identification information indicated by the identification structure of the PDU can be up or down. If the setting manner of the identification information needs to be switched between up and down, on the basis of the above-mentioned embodiments, a slot is arranged on the body structure, and the identification structure is fixedly arranged in the slot.

[0057] For example, the body structure is provided with a plurality of slots, each slot corresponding to a power outlet. The identification structure for indicating the identification information can be inserted into the slot and fixed in the slot. Further, as an example, the identification structure can be a signboard, and the signboard has the identification information. The signboard with the identification information is inserted into the slot along the slot and fixed in the slot.

[0058] Further, the front surface of the identification structure and the back surface of the identification structure are respectively printed with the identification information corresponding to the identification structure.

[0059] For example, in combination with the foregoing example, the identification structure can be a signboard. The front surface and the back surface of the signboard are respectively printed with the identification information corresponding to the identification structure. In one example, the identification information is printed on the front surface of the signboard in an upper position, and the identification information is printed on the back surface of the signboard in a lower position. Alternatively, the identification information can be printed on the front surface of the signboard in a lower position, and the identification information is printed on the back surface of the signboard in an upper position. Further, in combination with the foregoing example, the way of printing the identification information on the signboard can include but is not limited to laser etching, ink printing, carving, etc.

[0060] In the above example, by providing slots on the body structure of the power distribution unit and fixing the identification structure in the slots, the identification information of the power outlets on the power distribution unit can be flexibly changed according to the actual application, and the flexibility of the connection relationship between the electrical equipment in the cabinet and the power distribution unit is improved.

[0061] Since the body structure of the PDU has a plurality of surfaces. Therefore, on the basis of the above example, when the identification structure is provided on the PDU, it can be provided on any one of the plurality of surfaces.

[0062] In one example, the identification structure and the power outlet are located on the same surface of the body structure, and the outer surface of the identification structure is flush with the outer surface of the power outlet.

[0063] For example, a plurality of power outlets are provided on the first surface of the body structure of the PDU, and the identification structure is also provided on the same surface as the power outlets, i.e. the identification structure is also provided on the first surface. Alternatively, the identification structure can be provided on one side of the power outlet, and the identification structure can also be provided on both sides of the power outlet. Further, the outer surface of the identification structure can be flush with the outer surface of the power outlet.

[0064] In the above example, the identification structure and the power outlet are provided on the same surface, which can more clearly and intuitively determine the position information of the power outlet, so as to quickly determine which power outlet the power cord of the electrical equipment should be plugged into, and further improve the installation and maintenance efficiency of the electrical equipment.

[0065] In another example, the power outlets are located on a first surface of the body structure, and the identification structures are located on a second surface of the body structure adjacent to the first surface.

[0066] For example, Figure 4 A structure diagram of a power distribution unit provided in the present application Figure 3 As Figure 4 shown, a plurality of power outlets are provided on a first surface of the body structure of the PDU. The first surface is adjacent to a second surface, and each power outlet is provided with a corresponding identification structure on the second surface of the body structure of the PDU.

[0067] It should be noted that Figure 4 the power distribution unit shown in the figure only determines the identification information indicated in the identification structure in a lower position. The identification information indicated in the identification structure can also be determined in an upper position. The present example does not limit the way in which the identification information indicated in the identification structure is determined.

[0068] In the above example, since the identification structure is provided on the second surface adjacent to the first surface, the spatial volume of the power distribution unit can be further reduced.

[0069] On the basis of any of the preceding embodiments, the identification information represented by the identification structure corresponds to the outlet position corresponding to the electrical equipment in the cabinet.

[0070] For example, Figure 5 A corresponding relationship diagram of the example identification information and the electrical equipment position information. As Figure 5 shown in [a], the PDU determines the identification information indicated by the identification structure in a lower position. The position of a certain electrical equipment on the cabinet is [11U, 12U], and the power cord of the electrical equipment should be plugged into the power outlet corresponding to the PDU identification information [11U].

[0071] For example, as Figure 5 shown in [b], the PDU determines the identification information indicated by the identification structure in an upper position. The position of a certain electrical equipment on the cabinet is [11U, 12U], and the power cord of the electrical equipment should be plugged into the power outlet corresponding to the PDU identification information [12U].

[0072] The power distribution unit provided in the application can clearly reflect the connection relationship between the power equipment and the power socket by setting multiple power sockets on the body structure of the power distribution unit, setting corresponding identification structures for each power socket, and using the identification structures to indicate the position information of the power socket, and the position of each power socket corresponds to the position of the power equipment installed in the cabinet. Based on the clear connection relationship, the efficiency of installing the power equipment in the cabinet can be improved, and the risk and failure caused by unclear connection relationship when the power equipment is powered off during future maintenance can be avoided, which improves the efficiency and safety of the power equipment maintenance.

[0073] Figure 6 A structural schematic diagram of a power distribution device provided in the application is shown in FIG. 2. Figure 6 As shown in FIG. 2, the power distribution device 2 includes at least one power distribution unit 1 provided in the above embodiment, and each power distribution unit 1 in the power distribution device 2 is arranged on the same side of the inner wall of the cabinet.

[0074] For example, if the number of U positions of the cabinet is large and the number of installed power equipment is also large, the number of power sockets of one PDU may not meet the power supply requirements of the power equipment. Multiple PDUs can be installed on the same side of the inner wall of the cabinet, and the identification information indicated by the identification structure of each PDU can be continuous.

[0075] For example, if the power equipment is installed on [35U, 36U] in the cabinet, the power line of the power equipment can be inserted into the power socket corresponding to the identification information [35U] on the identification structure. If the power equipment is installed on [41U, 42U, 43U, 44U] in the cabinet, the power line of the power equipment can be inserted into the power socket corresponding to the identification information [41U, 43U] on the identification structure.

[0076] It should be noted that, Figure 6 The power distribution device shown in FIG. 2 only determines the identification information indicated by the identification structure in a lower position manner. The identification information indicated by the identification structure can also be determined in an upper position manner, and the embodiment does not limit the manner of determining the identification information indicated by the identification structure.

[0077] The power distribution device provided in the embodiment can flexibly combine the power distribution units when the number of power equipment in the cabinet is large by setting multiple power distribution units. At the same time, it can also avoid the waste of space position caused by using a power distribution unit with too many power sockets when the number of power equipment is small.

[0078] The application also provides a cabinet, at least one electrical equipment is arranged in the cabinet, and the electrical equipment in the cabinet is connected with the power distribution device provided in the above embodiment.

[0079] For example, at least one electrical equipment is arranged in the cabinet, and the power cord of the electrical equipment is connected with the power jack of the power distribution device provided in the above embodiment, so as to realize power supply to the electrical equipment.

[0080] Further, based on the power supply specification of the electrical equipment, the electrical equipment is usually provided with a main power cord and a backup power cord. The main power cord and the backup power cord need to be connected with the power distribution device respectively. Therefore, the main power distribution device and the backup power distribution device can be arranged in the cabinet. The power jack on the main power distribution device is used for connecting with the main power cord of the electrical equipment, and the power jack on the backup power distribution device is used for connecting with the backup power cord of the electrical equipment.

[0081] In an example, the bottom of the cabinet is provided with a slidable structure.

[0082] For example, the slidable structure can be arranged at the bottom of the cabinet. The slidable structure can include a base and a plurality of rollers arranged on the base. The cabinet is installed on the base, and the plurality of rollers are arranged on the base. The cabinet can be translated on the ground through the rollers.

[0083] Optionally, four rollers can be arranged on the base. The rollers can be directional wheels or universal wheels.

[0084] In the embodiment, the main power distribution device and the backup power distribution device are arranged in the cabinet, and the identification structure corresponding to the power jack is arranged on the main power distribution device and the backup power distribution device. The corresponding relationship between the power cord of the electrical equipment in the cabinet and the power jack can be clearly reflected, so as to improve the efficiency of installing the electrical equipment on the cabinet and the efficiency of maintaining the electrical equipment in the cabinet.

[0085] Finally, it should be noted that: other embodiments of the application will be easily conceived by those skilled in the art after considering the specification and practicing the application disclosed herein. The application is intended to cover any variations, uses or adaptations of the application that follow the general principles of the application and include known or customary technical means in the art of the application not disclosed herein, and is not limited to the precise structure described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the application is only limited by the appended claims.
