Some electrical equipment also features electronic control elements and a control panel; for ease of operation, the control panel is typically mounted at the front of the casing.

[0003] For some highly integrated electrical devices, such as power modules, fans and electronic control components, they are all mounted on the front of the housing, and the front of the housing is detachably connected to a face cover. The face cover is fixedly connected to the control panel and covers the fan and electronic control components.

[0004] Because the fan requires regular maintenance, the maintenance process involves disassembling and reassembling the front cover and the connection between the control panel and electronic control components, making the maintenance process complex and inefficient. Utility Model Content

[0041] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0042] Please refer to the following: Figures 1 to 6 The faceplate assembly provided by this utility model will now be described. The faceplate assembly includes a grille faceplate 1 located in front of the fan assembly and a control faceplate 2 electrically connected to the electronic control element; one end face of the grille faceplate 1 is spliced ​​with one end face of the control faceplate 2.

[0043] The inner side of one of the grille cover 1 and the control cover 2 is provided with a limiting part 3, and the inner side of the other is provided with a moving stop part 4; the moving stop part 4 abuts against the limiting part 3 in the inward and outward directions of the grille cover 1, and the moving stop part 4 extends outward from the cover assembly; wherein, when the extended part of the moving stop part 4 is moved, the moving stop part 4 can slide and disengage from the limiting part 3.

[0044] The faceplate assembly of this utility model is installed on the front opening surface of the electrical housing. The electrical housing contains electronic control components, electronic devices, and a heat dissipation assembly. The heat dissipation assembly generally includes a heat sink and a fan assembly. The heat sink absorbs heat from the electronic devices, and the fan assembly is located on the air intake side of the electronic devices to supply cool air to the heat sink. To ensure that the fan assembly receives cool air, it is generally located at the opening surface. Additionally, a filter screen is provided in front of the fan assembly to filter impurities in the incoming air. The electronic control components are also located at the opening surface for easy electrical connection with the control faceplate 2, facilitating operation. The grille faceplate 1 is located in front of the fan assembly to block it. The control faceplate 2 is located in front of the electronic control components to block them. Preferably, the fan assembly and electronic control components are spaced apart along the left-right direction of the electrical housing; therefore, the grille faceplate 1 and control faceplate 2 are also spliced ​​along the left-right direction of the electrical housing.

[0045] Both the grille cover 1 and the control cover 2 are cover structures with a certain thickness; in other words, both the grille cover 1 and the control cover 2 have an inner cavity. In addition, the grille cover 1 is equipped with a grille structure to ensure air intake. The control cover 2 is equipped with a control panel.

[0046] One end face of the grille cover 1 and one end face of the control cover 2 are spliced ​​together. To ensure the aesthetics of the cover assembly, there is no gap or only a very small gap at the splice between the grille cover 1 and the control cover 2. In addition to splicing, the grille cover 1 and the control cover 2 can also be limited by the abutment of the limiting part 3 and the moving stop part 4.

[0047] Specifically, the limiting part 3 is located inside the grille cover 1 or inside the control cover 2, and the moving stop part 4 is located inside the control cover 2 or inside the grille cover 1. It should be noted that the terms "inner" and "outer" are based on the orientation of the cover assembly after assembly. The side of the cover assembly facing the inside of the electrical housing is "inner", and the side facing the outside of the electrical housing is "outer".

[0048] The movable stop 4 has a first position and a second position. After the cover assembly is installed onto the opening surface of the electrical housing, the movable stop 4 is in the first position and abuts against the limiting part 3 in the inward and outward directions of the cover assembly. At this time, the grille cover 1 cannot be disengaged from the control cover 2.

[0049] When fan assembly maintenance or filter replacement is required, the movable stop 4 can be manually moved from the first position to the second position, disengaging from the limiting part 3. At this time, the grille cover 1 is not connected to the control cover 2, allowing the grille cover 1 to be quickly removed for filter replacement or fan assembly cleaning and maintenance. After maintenance, the grille cover 1 should be reattached to the opening of the electrical housing.

[0050] It should be noted that after the grating cover 1 is reinstalled, the movable stop 4 can be manually moved to switch from the second position to the first position, and re-engage with the limiting part 3. The movable stop 4 can also be connected to a reset structure. After the grating cover 1 is removed, the reset structure can switch the movable stop 4 from the second position to the first position. When the grating cover 1 is reinstalled, the manual fastening force can overcome the force of the reset structure. After the fastening force disappears, the reset structure moves the movable stop 4 back to the first position to engage with the limiting part 3.

[0051] Compared with the prior art, the face cover assembly provided by this utility model has a grille face cover 1 and a control face cover 2 spliced ​​together, which can seal the front opening of the electrical housing; a limiting part 3 and a moving stop part 4 are provided between the grille face cover 1 and the control face cover 2, and the moving stop part 4 and the limiting part 3 abut against each other in the inner and outer directions of the face cover assembly, so that the grille face cover 1 and the control face cover 2 can be relatively fixed; when it is necessary to maintain the fan assembly inside the housing, the moving stop part 4 can be moved manually to disengage the moving stop part 4 from the limiting part 3, and the grille face cover 1 can be removed without disconnecting the electronic control components, thus improving the efficiency of disassembly, assembly and maintenance.

[0052] In some embodiments, the aforementioned movable stop 4 may be adopted as follows: Figure 3 and Figure 5 The structure shown is described in the following document. Figure 3 and Figure 5 The movable stop 4 includes a stop structure 41 and a push block 42. The stop structure 41 abuts against the limiting part 3. The stop structure 41 has a first inclined surface 413. The first inclined surface 413 is inclined from the inside out in a direction away from the limiting part 3. One end of the push block 42 has a second inclined surface 421, and the other end extends outward from the cover assembly. The inclination direction of the second inclined surface 421 is the same as the inclination direction of the first inclined surface 413. When the push block 42 is pressed inward, the second inclined surface 421 abuts against the first inclined surface 413, and the push block 42 pushes the stop structure 41 away from the limiting part 3.

[0053] One end of the push block 42 is located inside the faceplate assembly and has a second inclined surface 421. The other end extends out of the faceplate assembly in the inward and outward directions, so the push block 42 can move in the inward and outward directions of the faceplate assembly. When the push block 42 is pressed manually, the second inclined surface 421 first abuts against the first inclined surface 413. If the push block 42 is pressed further, the second inclined surface 421 will push the first inclined surface 413 to move away from the limiting part 3, and finally the stop structure 41 will disengage from the limiting part 3.

[0054] The pushing direction of the pusher 42 is perpendicular to the moving direction of the stop structure 41. The pusher 42 moves in the inward and outward directions, so the stop structure 41 moves in a plane perpendicular to the inward and outward directions.

[0055] It should be noted that the travel of the push block 42 and the travel of the stop structure 41 are both small. That is to say, the contact area of ​​the stop structure 41 and the limiting part 3 is small. By moving the stop structure 41 with a small travel, the stop structure 41 can be disengaged from the limiting part 3.

[0056] Since the pusher 42 moves in the inward and outward directions, it is only necessary to open a through hole on the cover assembly for the pusher 42 to pass through. There is no need to set a groove on the outer surface of the cover assembly, which optimizes the shape and structure of the cover assembly and makes it easier for manual operation to apply force.

[0057] In some embodiments, the stop structure 41 described above may also employ, for example... Figure 3 , Figure 4 and Figure 5 The structure shown is described in the following document. Figure 3 , Figure 4 and Figure 5 The stop structure 41 includes a connecting plate 411 and a stop block 412. One end of the connecting plate 411 is connected to one of the grille cover 1 and the control cover 2; the stop block 412 is formed on the other end of the connecting plate 411; the stop block 412 has an abutment surface 414, the aforementioned first inclined surface 413 and third inclined surface 416, the abutment surface 414 and the first inclined surface 413 are respectively located on both sides of the connecting plate 411, the abutment surface 414 is used to abut against the limiting part 3; the third inclined surface 416 is connected to the abutment surface 414, and the inclination direction of the third inclined surface 416 is the same as the inclination direction of the first inclined surface 413.

[0058] The abutting surface 414 is perpendicular to the surface of the connecting plate 411, and the first inclined surface 413 is inclined relative to the surface of the connecting plate 411. The abutting surface 414 and the first inclined surface 413 are located on both sides of the connecting plate 411 and will not affect each other. The abutting surface 414 will not interfere with the movement of the push block 42.

[0059] Preferably, one end of the connecting plate 411 is integrally formed with the inner side of the faceplate assembly. The other end of the connecting plate 411 is a free end, and the stop block 412 is formed on the free end. The connecting plate 411 not only serves to support the stop block 412, but more importantly, the fact that one end of the connecting plate 411 is fixed while the other end is free allows the connecting plate 411 to swing slightly around its fixed end. When the second inclined surface 421 pushes the first inclined surface 413 to move, the stop block 412 causes the connecting plate 411 to swing slightly. When the push block 42 returns to its original position, the first inclined surface 413 loses its limiting position, the connecting plate 411 swings back, and causes the stop block 412 to return to its original position.

[0060] The connecting plate 411 not only supports the stop block 412, but also serves to reset the stop block 412. Therefore, the stop structure 41 does not require an external reset structure, which simplifies its structure and makes it easier to design and form.

[0061] It should be noted that when reinstalling the grille cover 1, it is necessary to manually fasten the grille cover 1 onto the opening surface of the electrical housing. Since the stop block 412 also has a third inclined surface 416, the outer edge of the third inclined surface 416 is located outside the limiting part 3. During the fastening process of the grille cover 1, the third inclined surface 416 first abuts against the wall surface of the limiting part 3, and the limiting part 3 will squeeze the third inclined surface 416, causing the stop block 412 and the connecting plate 411 to swing slightly, so that the stop block 412 can smoothly pass inward through the limiting part 3. After the fastening thrust disappears, the connecting plate 411 returns to its original position, and the abutting surface 414 abuts against the limiting part 3.

[0062] Please refer to Figure 3 and Figure 5 Based on the above embodiments, the stop block 412 is provided with a groove 415, the groove opening of the groove 415 faces the control surface cover 2, and one side of the groove wall of the groove 415 is a first inclined surface 413.

[0063] The groove 415 is located on one side of the connecting plate 411 and is not connected to the abutment surface 414. Designing one side wall of the groove 415 as a first inclined surface 413 can reduce the overall height of the stop block 412, thereby reducing the volume occupied by the stop structure 41. It can also reduce the bearing pressure on the connecting plate 411, making the support and slight sway of the connecting plate 411 more stable, and the connecting plate 411 will not easily break.

[0064] The groove 415 can be a through groove in the inward or outward direction, or it can be a non-through groove. If it is a through groove, a limiting surface can be provided between the push block 42 itself and the cover assembly to limit the movement stroke of the push block 42. If it is a non-through groove, the bottom wall of the groove 415 can be set as a limiting surface to limit the movement stroke of the push block 42.

[0065] In some embodiments, the mounting position of the stop structure 41 can be as follows: Figure 3 and Figure 4 The structure shown is described in the following document. Figure 3 and Figure 4 An avoidance opening 21 is provided on the splicing end face of the control cover 2; the connecting plate 411 is located at the avoidance opening 21, and the abutment surface 414 extends toward the splicing end face of the grid cover 1.

[0066] A stop structure 41 is provided on the control cover 2, and a push block 42 passes through the control cover 2 in the inward and outward directions. A limiting part 3 is provided on the grille cover 1. Since the grille cover 1 needs to be frequently disassembled and reassembled, the stop structure 41, which can move and is supported only by the connecting plate 411, is provided on the control cover 2, which does not need to be frequently disassembled and reassembled. The stop structure 41 can be shielded and protected by the control cover 2, thereby avoiding damage caused by accidental contact.

[0067] An avoidance opening 21 is provided on the splicing end face of the control cover 2, and the connecting plate 411 is located at the avoidance opening 21. This facilitates the placement of the connecting plate 411, allowing the stop block 412 to approach the limiting part 3, and also provides avoidance space for the connecting plate 411 to swing.

[0068] Preferably, the stop structure 41 is integrally formed with the splicing end face of the control cover 2, that is, one end of the connecting plate 411 is integrally formed with the splicing end face of the control cover 2, and the stop block 412 is integrally formed with the other end of the connecting plate 411.

[0069] The one-piece molding structure ensures that the connecting plate 411 has the freedom to swing slightly around its fixed end, and there is no need to assemble the stop structure 41. The stop structure 41 and the control cover 2 can be injection molded.

[0070] In some embodiments, the aforementioned grille cover 1 may adopt the following... Figure 6 The structure shown is described in the following document. Figure 6 The splicing end face of the grille cover 1 is provided with a concave area 11, and the limiting part 3 is formed in the concave area 11.

[0071] The recessed area 11 is used to avoid the stop structure 41 and to accommodate the limiting part 3. This prevents the stop structure 41 from colliding with and being damaged by the splicing end face of the grille cover 1 during installation.

[0072] Based on the same inventive concept, this application also provides an electrical device, including an electrical housing and the aforementioned cover assembly. The front end face of the electrical housing is an open face, and a fan assembly and electronic control components are disposed inside the electrical housing at the open face. A grille cover 1 is located in front of the fan assembly and blocks the fan assembly. A control cover 2 is located in front of the electronic control components and is electrically connected to the electronic control components. Preferably, the control cover 2 is fixed to the open face of the electrical housing using bolts.

[0073] The electrical housing, as the outer shell structure of electrical equipment, is generally hexahedral in shape, comprising two side plates, a bottom plate, a top plate, and a back plate. Besides the fan assembly and electronic control components, the internal cavity of the electrical housing also houses other electronic devices. The fan assembly is located at the open surface, i.e., in front of the electronic devices, and is used to supply cool air to the electrical devices. The electronic control components are also located at the open surface for easy electrical connection with the control cover 2, facilitating operation. Preferably, the fan assembly and electronic control components are spaced apart along the left-right direction of the electrical housing; therefore, the grille cover 1 and the control cover 2 are also spaced apart along the left-right direction of the electrical housing.

[0074] It should be noted that the opening surface defined above refers to the front face of the electrical housing because the fan assembly is generally installed on the air intake side of the electronic device, and because facing the control cover 2 forward makes manual operation more convenient. However, when the electrical housing is used in a specific fixed position, the opening surface can face forward or in other directions; that is, the opening surface can be any face of the electrical housing. This embodiment defines the opening surface as the front face of the electrical housing only to facilitate the explanation of the positional relationship between the cover assembly, the fan assembly, and the electronic control components.

[0075] The electrical housing provided by this utility model has a grille cover 1 and a control cover 2 spliced ​​together, which can seal the front opening of the electrical housing. A limiting part 3 and a moving stop part 4 are provided between the grille cover 1 and the control cover 2. The moving stop part 4 and the limiting part 3 abut against each other in the inner and outer directions of the cover assembly, which can fix the grille cover 1 and the control cover 2 relatively. When it is necessary to maintain the fan assembly inside the housing, the moving stop part 4 can be moved manually to disengage it from the limiting part 3, and the grille cover 1 can be removed without disconnecting the electronic control components, thus improving the efficiency of disassembly, assembly and maintenance. Moreover, during maintenance operations, the electronic control components are shielded by the control cover 2, which can prevent dust and other impurities from adhering and reduce the impact on the electronic control components.

[0076] In some embodiments, the above-mentioned grille cover 1 may also adopt the following: Figure 6 The structure shown is described in the following document. Figure 6 An elastic pusher 5 is provided on the inner side of the grille cover 1. The elastic pusher 5 is close to the splicing end face of the grille cover 1 and abuts against the opening face.

[0077] The elastic pusher 5 is positioned between the grille cover 1 and the opening surface, and it stores elastic energy. When the pusher 42 is manually pressed to disengage the stop block 412 from the limiting part 3, the grille cover 1 and the control cover 2 lose connection. At this time, the elastic pusher 5 releases its stored energy and pushes the splicing end of the grille cover 1 outward to assist in disassembly.

[0078] In addition, a buckle 6 is provided on the other end of the grille cover 1, which is engaged with the opening surface. The buckle 6 engages with the opening surface of the electrical housing to enhance the fixing strength of the grille cover 1. The splicing end of the grille cover 1 is abutted and limited by the stop structure 41 and the limiting part 3, and the other end is engaged by the buckle 6, thereby ensuring that the grille cover 1 is stable after installation and will not have the problem of edge lifting.

[0079] When disassembling the grating cover 1, the elastic pusher 5 lifts the splicing end of the grating cover 1, and the snapping direction of the buckle 6 also deflects slightly, making it easier for personnel to apply force to pull the grating cover 1 outward.

[0080] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
