[0042] Please refer to Figures 1 to 9 , and now the easy-to-maintain quick-installable lintel structure provided by the present utility model will be described. The easy-to-maintain quick-installable lintel structure includes a lintel installation main body 1. The front side of the lintel installation main body 1 is used for installing a lintel, and the rear side of the lintel installation main body 1 faces the skylight system of the data center; a receiving groove 10 is formed at the top of the lintel installation main body 1, and a top interface 20 is provided in the receiving groove 10; a first front interface 30 and a second front interface 40 are provided on the front side of the lintel installation main body 1. The first front interface 30 is located on the left side of the lintel installation main body 1, and the second front interface 40 is on the right side of the lintel installation main body 1; side interfaces 50 are respectively provided on the left and right sides of the lintel installation main body 1; the top interface 20, the first front interface 30, the second front interface 40 and the side interfaces 50 are all plug-in interfaces.

[0043] In this embodiment, interface wires electrically connected to the top interface 20, the first front interface 30, the second front interface 40, and the side interface 50 are provided inside the lintel installation main body 1, and corresponding electrical components are also provided. The top interface 20, the first front interface 30, the second front interface 40, and the side interface 50 are electrically connected to the corresponding modules respectively through quick plugs to achieve electrical connection. Connectors are also respectively provided on the lead wires of each module to achieve plug-in power connection.

[0044] More specifically, the top interface 20 is divided into an AC interface 210, a communication interface 220, and a DC interface 230, and the AC interface 210, the communication interface 220, and the DC interface 230 are distributed in the left-right direction. When there are multiple AC interfaces 210, the multiple AC interfaces 210 are centrally arranged and are all distributed in the left-right direction; the communication interface 220 and the DC interface 230 are also distributed in a similar manner, which will not be elaborated here. The communication interface 220 is used to connect to modules such as temperature sensors, smoke sensors, and signal collectors, the DC interface 230 is used to connect to modules such as lighting lamps, cameras, and projection lamps, and the AC interface 210 is used to connect to modules such as skylight magnetic locks. These modules are mainly arranged in the upper part of the data center, and the top interface 20 realizes the nearby connection with these modules, with a shorter wiring path and lower connection and cable management difficulty.

[0045] In this embodiment, there are multiple first front interfaces 30, which respectively realize the connection with modules such as the lintel and the ambient light. These modules are mainly arranged on the right side of the data center, and the first front interface 30 realizes the nearby connection with these modules, with a shorter wiring path and lower connection and cable management difficulty. Among them, a light source component is provided inside the lintel, so power connection is required.

[0046] In this embodiment, there are multiple second front interfaces 40, which respectively realize the connection with modules such as access control integrated machines, audible and visual alarms, automatic doors, touch screens, and ambient lights. These modules are mainly arranged on the left side of the data center, and the second front interface 40 realizes the nearby connection with these modules, with a shorter wiring path and lower connection and cable management difficulty.

[0047] In this embodiment, the side interface 50 is divided into a left side interface and a right side interface. The left side interface is located on the left side of the lintel installation main body 1, and the right side interface is located on the right side of the lintel installation main body 1. The left side interface realizes the connection with modules such as lighting buttons and infrared sensors on the left column 2, and the right side interface realizes the connection with modules such as exit buttons and infrared sensors on the right column 2, and also achieves the effect of nearby connection.

[0048] The easily maintainable quick-installable lintel structure provided in this embodiment, compared with the prior art, utilizes the top space of the lintel installation main body 1 to set the top interface 20. The top interface 20 is protected by the accommodation groove 10 and will not protrude from the lintel installation main body 1, which can meet the wiring requirements of top modules in the data center (such as camera, sensor and other modules); the front side of the lintel installation main body 1 is used to set the first front interface 30 and the second front interface 40 to meet the wiring requirements of modules such as the atmosphere lights around the lintel and the end door, which are arranged on the column 2 and the lintel installation main body 1; the side spaces on both sides of the lintel main body are used to set the side interfaces 50 to realize the wiring requirements of modules such as access control and touch screens, which are arranged on the column 2 and the end trim plate 3. The overall easily maintainable quick-installable lintel structure in this embodiment can be prefabricated in the factory to form an integral module, and the corresponding modules can be quickly wired and disconnected in a plug-and-play manner through plugging. Wiring and disconnection can be directly carried out without tools, and there is no need to thread wires and find wires on site. Both on-site construction and later maintenance are more convenient; at the same time, the peripheral space of the lintel main body is fully utilized, and interfaces are set on the top, front and rear sides to meet the wiring requirements of modules in different areas, making docking easier, greatly improving the construction convenience, and being beneficial to reducing the maintenance cost.

[0049] In addition, based on this embodiment, the interfaces and corresponding markings of different end doors are all designed in a generalized manner, and the operations of factory manufacturing and on-site construction are roughly the same standardized processes, which makes it easier for operators to be proficient in construction and further reduces the manufacturing and use costs.

[0050] In some embodiments, the above-mentioned lintel installation main body 1 can adopt the structure as Figures 1 to 5 shown. The lintel installation main body 1 includes a lintel outer shell 60 and an accommodation box 70. The top of the lintel outer shell 60 forms an installation opening, and the accommodation box 70 is installed within the installation opening. The accommodation box 70 is a box body structure with an open top. The accommodation box 70 forms an accommodation groove 10. The bottom surface of the accommodation box 70 is an inclined surface that gradually slopes downward from front to back. The top interface 20 is arranged on the bottom surface of the accommodation box 70; the first front interface 30 and the second front interface 40 are arranged on the front side of the lintel outer shell 60, and side interfaces 50 are arranged on the left and right sides of the lintel outer shell 60 respectively. In this embodiment, the inside of the lintel outer shell 60 is used to accommodate the wires of each interface and other supporting electrical components, and the front side of the outside is used to assemble the lintel. The space utilization rate of the lintel outer shell 60 is relatively high; the accommodation box 70 is set to provide a fixed platform for the top interface 20 and can also play a protective role for the top interface 20. In addition, due to the inclined setting of the bottom surface of the accommodation box 70, the top interface 20 is also inclined. When wiring, it is convenient for the operator to align and plug into the top structure. The inclined design can also effectively avoid water accumulation or dust around the top interface 20, and water or dust and other dirty substances all flow to the low position of the bottom surface, avoiding the influence of dirty substances on the reliability of wiring.

[0051] See Figure 4 In some specific embodiments of the accommodation box 70, for the convenience of connecting with the lintel housing 60, the left and right edges of the top opening of the accommodation box 70 are bent away from its own opening to form connecting flanges 710, and the connecting flanges 710 are in fitting connection with the top surface of the inner cavity of the lintel housing 60. The connecting flanges 710 do not block the top opening of the accommodation box 70, thus avoiding affecting the plugging and unplugging of the top interface 20. At the same time, the contact area between the accommodation box 70 and the lintel housing 60 is effectively increased. The connecting flanges 710 and the lintel housing 60 have a relatively high bonding strength in the fitting connection, and can better withstand the force of reverse plugging and unplugging, avoiding the detachment of the accommodation box 70.

[0052] In some specific embodiments of the accommodation box 70, see Figure 2 The front plate of the accommodation box 70 does not protrude beyond the front edge of the installation opening, and the rear plate of the accommodation box 70 protrudes upward beyond the rear edge of the installation opening. The protruding design of the rear plate of the accommodation box 70 can block and position the components (such as a fixed skylight) on the rear side of the lintel housing 60, avoiding the forward protrusion of the rear side components and occupying the space above the accommodation box 70, resulting in the problem that the connectors of the functional modules cannot extend into the accommodation box 70 and affecting the wiring operation; the non-protruding design of the front plate of the accommodation box 70 avoids protruding beyond the lintel, thus avoiding the problem of affecting the overall appearance of the area where the lintel is located.

[0053] Refer to Figure 2 、 Figures 5 to 8 In some embodiments, a maintenance opening 601 is provided on the rear side of the lintel housing 60, and a cover plate 80 is detachably provided at the maintenance opening 601. When maintenance is required, the cover plate 80 is disassembled, and the maintenance opening 601 directly exposes the electrical components and wires inside the lintel installation main body 1, facilitating maintenance. More specifically, the four sides of the maintenance opening 601 are as close as possible to the edge of the lintel housing 60 to maximize the opening area of the maintenance opening 601 and facilitate maintenance operations.

[0054] On the basis of the above embodiments, see Figures 5 to 8 To achieve the detachable connection between the cover plate 80 and the lintel housing 60, buckles 90 are respectively provided on the left and right sides of the cover plate 80, and clamping grooves 602 are respectively formed on the left and right sides of the maintenance opening 601, and the buckles 90 are snap-fitted with the clamping grooves 602. The detachable connection is achieved through the snap-fitting form, and the disassembly and assembly are simpler. At the same time, the bilateral snap-fitting method also ensures the reliability of the assembly and avoids the detachment of the cover plate 80.

[0055] On the basis of providing the buckles 90, see Figure 8 A limiting edge 610 is further formed on the side of the maintenance opening 601, and the limiting edge 610 abuts against the front side of the cover plate 80 for limiting, restricting the stroke range of the forward movement of the cover plate 80 and ensuring the reliability of the assembly.

[0056] In some specific embodiments, referring to Figure 7 , an assembly port 801 is provided at a position near the edge of the cover plate 80. The buckle 90 includes an assembly main body 910, a rear side limiting body 920, and a buckle 90 main body. The front side limiting body is provided at the rear side edge of the assembly main body 910, and the buckle 90 main body is provided at the front side edge of the assembly main body 910 and extends in the left-right direction. The inner diameter of the assembly port 801 is larger than the outer diameter of the assembly main body 910 but smaller than the outer diameter of the rear side limiting body 920. When being engaged with the card slot 602, the buckle 90 main body abuts against the rear side wall of the card slot 602, and the rear side limiting body 920 abuts against the rear plate surface of the cover plate 80, thereby realizing the clamping and limiting in the front-rear direction.

[0057] More specifically, a step 940 is further provided between the buckle 90 main body and the assembly main body 910 to enhance the connection strength between the buckle 90 main body and the assembly main body 910. In addition, an avoidance groove 802 corresponding to the buckle 90 main body is formed at the edge of the cover plate 80. While facilitating the assembly, it can avoid the buckle 90 occupying too much space on the front side of the cover plate 80 and improve the compactness of the structure.

[0058] In some embodiments, referring to Figure 7 , in order to facilitate the application of force during assembly, an operation groove 950 is formed on the rear side surface of the assembly main body 910.

[0059] Referring to Figure 5 and Figure 6 , in some embodiments, there are multiple cover plates 80. The multiple cover plates 80 are joined together in the up-down direction to cover the maintenance opening 601, and each cover plate 80 is respectively provided with a buckle 90. The single cover plate 80 is miniaturized, and each cover plate 80 is detachably connected to the lintel housing 60. The difficulty of disassembling and assembling the cover plate 80 is smaller. During maintenance, one or more cover plates 80 can be selectively disassembled as needed, and the usage method is more flexible. This embodiment exemplarily shows an embodiment in which there are two cover plates 80 and the two cover plates 80 are joined together in the up-down direction.

[0060] Referring to Figure 2 and Figure 6 , in some embodiments, a lifting frame 810 is further provided on the front plate surface of the cover plate 80. The lifting frame 810 lifts the bottom of the accommodation box 70. On the one hand, it can play a supporting role for the accommodation box 70 and improve its bearing performance during insertion. On the other hand, it can also play a certain pre-positioning role for the cover plate 80 when installing the cover plate 80.

[0061] On the basis of the above embodiments, referring to Figure 2 and Figure 6, the lifting bracket 810 includes a connecting plate 811 and a lifting plate 812. The connecting plate 811 is fitted and connected to the cover plate 80. The lifting plate 812 is provided at the upper edge of the connecting plate 811 and extends forward. The bottom plate of the accommodating box 70 includes an interface plate body 720 and a positioning plate body 730 connected to the rear side edge of the interface plate body 720. The interface plate body 720 gradually inclines downward from front to back, and the top interface 20 is provided on the interface plate body 720. The plate surface of the positioning plate body 730 is perpendicular to the up and down direction, and the lower plate surface of the positioning plate body 730 is in close contact with the lifting plate 812. Among them, the connecting plate 811 is perpendicular to the lifting plate 812. In this embodiment, the connecting plate 811 contacts the cover plate 80 in a surface contact manner, and the two are connected by threaded fasteners, with a relatively high bonding strength and better load-bearing performance. The lifting plate 812 is provided at the upper edge of the connecting plate 811, which does not affect the assembly of the connecting plate 811. At the same time, it can better provide a supporting effect, and its surface contact with the positioning plate body 730 provides better supporting stability.

[0062] Based on the same inventive concept, the embodiment of the present application further provides a data center, including the above-mentioned easy-to-maintain quick-installable lintel structure.

[0063] Compared with the prior art, the data center provided in this embodiment greatly reduces the wiring construction difficulty and the later maintenance difficulty by adopting the above-mentioned easy-to-maintain quick-installable lintel structure, thereby facilitating the reduction of the overall construction and maintenance costs of the data center.

[0064] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
