Description

Technical Field

[0001] This utility model relates to the field of chassis technology, and in particular to a novel non-standard chassis. Background Technology

[0002] Non-standard chassis are customized metal enclosures used in the industrial field to meet specific needs, primarily for applications such as instrumentation and security monitoring. However, because non-standard chassis require the integration of numerous components, a large number of bolts and screws are needed to connect and secure these components to the chassis, resulting in an inefficient connection method. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a new type of non-standard chassis, in which the panel arrangement of each component is more reasonable.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A novel non-standard chassis, constructed as a rectangular enclosure, includes: an enclosure body and components disposed within the enclosure body; the first sidewall of the enclosure body facing the user includes at least a first panel and at least a second panel joined together, the first panel extending into the enclosure body with a first extension segment, and the second panel extending into the enclosure body with a second extension segment; wherein, the first extension segment is provided with a first connecting bolt through its own thickness direction, and the second extension segment is provided with a second connecting bolt along its own thickness direction, and both the first connecting bolt and the second connecting bolt are located inside the enclosure body; the first connecting bolt and the second connecting bolt are adapted to connect with the components.

[0006] Furthermore, the component includes a fan box, the first panel is the fan box panel of the fan box, and the first connecting bolt is connected to the fan box housing spliced ​​to the edge of the fan box panel.

[0007] Furthermore, the first extension is a rib provided on the fan box panel facing the inside of the box.

[0008] Furthermore, one side of the rib along the thickness direction is fitted to the fan housing, and the rib has a first bolt hole for mounting the first connecting bolt.

[0009] Furthermore, the component includes a PCB mounting assembly, the second panel is a plug-in mounting panel of the PCB mounting assembly, and the second connecting bolt is connected to the PCB board in the PCB mounting assembly.

[0010] Furthermore, the second extension is a boss extending toward the interior of the housing on the plug-in mounting panel, and the boss is integrally formed with the plug-in mounting panel.

[0011] Furthermore, the second extension includes a first segment extending from the plug-in mounting panel, a second segment extending from the end of the first segment, the first segment and the second segment forming a stepped surface, the stepped surface being fitted to the edge of the PCB board.

[0012] Furthermore, the second segment has a first bolt hole, which matches a preset hole on the PCB board, and the second connecting bolt passes through the first bolt hole and the preset hole.

[0013] Furthermore, the second extension is a cutable profile on the panel.

[0014] The beneficial effects of this utility model are as follows: By extending the first and second extension sections into the interior of the housing, the first bolt holes, which originally needed to be drilled on the panel surface, are moved to the vertical thickness direction of the extension sections. This allows the tightening directions of the first and second connecting bolts to form a spatial orthogonal relationship with the panel plane, thus achieving a stable connection between the panels without penetrating the outer surface of the panel. This eliminates the damage to the integrity of the profile cross-section caused by dense openings, and the concealed bolt layout makes the panel more aesthetically pleasing. Simultaneously, the increased contact area between the extension sections and the internal frame of the housing allows for the formation of a three-dimensional load-bearing support structure through multi-point bolt tightening, further enhancing the overall deformation resistance of the spliced ​​panels.

[0028] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] See Figures 1-6 This utility model provides a technical solution:

[0030] A novel non-standard chassis includes: a rectangular chassis 100 and components disposed within the chassis 100.

[0031] The enclosure 100 typically integrates user-controlled components on one side of the rectangular enclosure 100, so that this side faces the user for easy operation. (Reference) Figure 1 As shown in the figure, the first sidewall 11 of the box 100 facing the user is provided with multiple height-adjustable lifting aids 123, specifically including a first panel 110 and multiple second panels 120 spliced ​​together. Handles 130 are also provided on both sides of the first sidewall 11 for easy access by the user.

[0032] In the prior art, since the first sidewall 11 facing the user in the chassis includes multiple spliced ​​second panels 120 and first panels 110, a large number of bolts are needed to connect and fix the first panels 110 and second panels 120 to the other sidewalls of the chassis in order to fix the above multiple panel structures. This results in too many bolts on the side facing the user. On the one hand, setting multiple first bolt holes 1111 in the limited panel space makes the processing more difficult and weakens the strength of the profile; on the other hand, it also affects its appearance.

[0033] Therefore, in this embodiment, the first panel 110 extends into the housing 100 with a first extension section 111, and the second panel 120 extends into the housing 100 with a second extension section 121. The first extension section 111 is provided with a first connecting bolt through it along its own thickness direction, and the second extension section 121 is provided with a second connecting bolt along its own thickness direction. Both the first connecting bolt and the second connecting bolt are located inside the housing 100.

[0034] In this way, by extending the first extension section 111 and the second extension section 121 into the housing 100, the first bolt hole 1111, which originally needed to be drilled on the panel surface, is moved to the vertical thickness direction of the extension section. This makes the tightening directions of the first and second connecting bolts spatially orthogonal to the panel plane, thus achieving a stable connection between the panels without penetrating the outer surface of the panel. This eliminates the damage to the integrity of the profile cross-section caused by dense openings, and the concealed bolt layout makes the panel more aesthetically pleasing. At the same time, the increased contact area between the extension section and the internal frame of the housing 100 allows for the formation of a three-dimensional load-bearing support structure through multi-point bolt tightening, further enhancing the overall deformation resistance of the spliced ​​panels.

[0035] To ensure that both the first connecting bolt and the second connecting bolt are located inside the housing 100, in this embodiment, the first connecting bolt and the second connecting bolt are adapted to be connected to the component.

[0036] Of course, the first panel 110 and the second panel 120 are listed in the above description to illustrate the structure of this embodiment more intuitively, and are not intended to limit the panels facing the user side in this application embodiment to two types of panels, which can be one type or more types.

[0037] In some embodiments, reference is made to Figure 2 As shown, the component includes a fan housing, the first panel 110 is the fan housing panel of the fan housing, and the fan housing also includes a fan housing shell 12, which is constructed as a rectangular shell and spliced ​​with the fan housing panel to form a closed cavity; as Figure 3 As shown, the fan housing 12 is fitted to the side wall of the housing 100, and the fan installed inside is not shown in the figure.

[0038] Thus, the fan box housing 12 is connected to the edge of the fan box panel by the first connecting bolt, and the first extension section 111 is a rib provided on the side of the fan box panel facing the inside of the housing 100.

[0039] For details, please refer to Figure 4As shown, the fan housing has several first through holes a, and one side of the rib along the thickness direction is fitted to the fan housing 12, with first bolt holes 1111 formed on the rib. During installation, the first connecting bolts are passed through the first through holes a on the fan housing and the first bolt holes 1111 formed on the rib. Auxiliary mounting bolts 13 are provided at both ends of the fan housing panel to further assist in fixing the fan housing panel. Based on the above installation structure, the first connecting bolts are hidden inside the housing 100, reducing the number of bolts visible on the side of the housing 100 facing the user. The ribs improve the connection strength of the structure while increasing aesthetics.

[0040] In some embodiments, the component includes a PCB mounting assembly, the second panel 120 is a plug-in mounting panel of the PCB mounting assembly, and the second connecting bolt is connected to the PCB board 14 in the PCB mounting assembly. Multiple plug-in mounting panels are sequentially spliced ​​together side-by-side, and the wide side of each plug-in mounting panel is spliced ​​to the fan box panel.

[0041] In some examples, the plug-in mounting panel may also extend ribs from its longitudinal end toward the interior of the housing 100 to securely connect the plug-in mounting panel to the housing 100. Subsequently, as shown in... Figure 1 and Figure 5 The example shown illustrates a structure on the plug-in installation panel that does not include ribs.

[0042] refer to Figure 1 and Figure 5 As shown, the plug-in mounting panel has several second through holes b for mounting fixing bolts, and the heads of the fixing bolts are visible on the plug-in mounting panel; the second extension 121 is a boss extending from the plug-in mounting panel toward the interior of the housing 100, and the boss is integrally formed with the plug-in mounting panel, and has second bolt holes 1211 in its thickness direction for fixing the second connecting bolts. Figure 5 As shown, the plug-in mounting panel has a shielding strip 124 at its edge on the side facing inward of the housing 100, and a second extension section 121 extends from the outer side of the shielding strip 124.

[0043] It is worth noting that conventional plug-in mounting panels are designed based on the specifications of the standard GB / T 19520. The connection between the plug-in mounting panel and the PCB is generally achieved by using a connector. A countersunk hole needs to be made on the plug-in mounting panel to fix the plug-in mounting panel and the connector with countersunk screws. Then, screws are used to fix the PCB and the connector, thereby achieving the effect of fixing the plug-in mounting panel and the PCB board 14.

[0044] However, this installation method presents several problems. First, the countersunk holes and screws on the mounting panel affect its aesthetics. Second, there are no limiting mechanisms between the standard connector and the mounting panel; without specific tooling fixtures, it is difficult to assemble them parallel to the mounting panel manually, thus affecting the assembly of PCB board 14. Furthermore, since the connectors and mounting panels are packaged by the manufacturer and sent to the subsequent assembler or directly to the user, neither the user nor the assembler is familiar with the structure of the non-standard enclosure 100; and because the connectors lack foolproof markings, they may be installed in the wrong orientation.

[0045] In contrast, this example incorporates an integral second extension 121 on the plug-in mounting panel, perpendicular to the panel for connecting the PCB board 14, thus eliminating the need for a connector. This eliminates the need for a connector-to-plug-in mounting panel pairing process, preventing issues caused by incorrect connector installation. Furthermore, by directly creating a second bolt hole 1211 on the second extension 121 for mating with the PCB board 14, there is no need to create additional countersunk holes on the plug-in mounting panel, thus eliminating the problem of difficulty in mounting the connector to the PCB board 14.

[0046] In some examples, the second extension 121 is a cutable profile on the panel, and the second bolt hole 1211 on the second extension 1213 matches a pre-set hole on the PCB board 14. The second connecting bolt passes through the second bolt hole 1211 and the pre-set hole. Therefore, after manufacturing the second extension 121 to the required length as specified, the excess portion is cut off, leaving only a portion for mounting the PCB board 14. Then, the second bolt hole 1211 is tapped and a wire thread insert is inserted. Finally, the PCB board 14 is installed. The structure after installation is as follows: Figure 6 As shown; therefore, the above structure can be used for plug-in mounting panels of any width, for mounting PCB boards 14 of any size, and for mounting multiple PCB boards 14 on the same plug-in mounting panel.

[0047] Furthermore, the second extension 121 includes a first segment 1212 extending from the plug-in mounting panel, and a second segment 1213 extending from the end of the first segment 1212. The first segment 1212 and the second segment 1213 form a stepped surface, which is fitted to the edge of the PCB board 14. In other words, the end face of the first extension 111 is adapted to abut against the edge of the PCB board 14, and the sidewall of the stepped surface of the second extension 121 is adapted to fit against the surface of the PCB board 14. Thus, during installation by the assembler or user, the positioning process can be quickly completed using the stepped surface.

[0048] Therefore, in this embodiment, the plug-in mounting panel can omit the connector, reducing costs while directly connecting the plug-in mounting panel to the PCB board 14. This eliminates the countersunk holes and countersunk screws on the front of the plug-in mounting panel, improving its appearance. At the same time, the installation method is simpler, avoiding installation errors or non-parallel installation problems that may occur when installing connectors, saving assembly time and reducing assembly difficulty.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
