[0047] In order to make the technical problems, technical schemes and beneficial effects to be solved by the utility model more clearly understood, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0048] Please refer to Figures 1 to 10The face cover assembly is used for being buckled at the front end opening surface of the electrical shell, and comprises a control face cover 1, a grating face cover 2 and a decorative plate 4. The control face cover 1 is fixedly connected with the electrical shell; one end surface of the grating face cover 2 is spliced with one end surface of the control face cover 1; the inner side of the grating face cover 2 is provided with a connecting structure 3, the connecting structure 3 is detachably connected with the control face cover 1 and / or the electrical shell; the decorative plate 4 is arranged on the outer side of the grating face cover 2; the decorative plate 4 is connected with an inner extending structure 5, and the inner extending structure 5 passes through the grating face cover 2 and is connected with the connecting structure 3.

[0049] The face cover assembly of the utility model is installed on the front end opening surface of the electrical shell, the inside of the electrical shell is provided with electronic control elements, electronic devices and a heat dissipation assembly, the heat dissipation assembly generally comprises a radiator and a fan assembly, the radiator absorbs the heat of the electronic devices, and the fan assembly is located at the air inlet side of the electronic devices to supply cold air to the radiator. In order to ensure that the fan assembly receives cold air, the fan assembly is generally arranged at the opening surface, in addition, in order to filter the impurities in the air inlet, a filter screen is also arranged in front of the fan assembly. The electronic control elements are also located at the opening surface, so as to be electrically connected with the control face cover 1, and personnel operation is facilitated.

[0050] Specifically, the grating face cover 2 is located in front of the fan assembly to block the fan assembly. The control face cover 1 is located in front of the electronic control elements to block the electronic control elements, and is electrically connected with the electronic control elements, since the electronic control elements do not need to be frequently maintained, therefore, the control face cover 1 is fixed on the front end opening surface of the electrical shell by bolts.

[0051] Preferably, the fan assembly and the electronic control elements are distributed along the left-right direction of the electrical shell, therefore, the grating face cover 2 and the control face cover 1 are also spliced along the left-right direction of the electrical shell.

[0052] The grating face cover 2 and the control face cover 1 are both cover structures with certain thickness, in other words, the grating face cover 2 and the control face cover 1 both have inner cavities; in addition, the grating face cover 2 is provided with a grating structure to ensure air inlet. The control face cover 1 is provided with a control panel, and the control panel is electrically connected with the electronic control elements.

[0053] One end surface of the grating face cover 2 and one end surface of the control face cover 1 are spliced, in order to ensure the appearance of the face cover assembly, there is no gap or only a small gap at the splicing position of the grating face cover 2 and the control face cover 1. In addition to splicing, the grating face cover 2 and the control face cover 1 can also be connected through the connecting structure 3. Of course, the grating face cover 2 and the control face cover 1 can only have a splicing relationship, and the grating face cover 2 is fixed on the electrical shell through the connecting structure 3.

[0054] The connecting structure 3 is arranged at the inner side of the grid cover 2, and it is to be noted that the "inner" and "outer" are based on the direction of the assembled cover assembly, wherein the side of the cover assembly facing the inside of the electrical cabinet is "inner", and the side facing the outside of the electrical cabinet is "outer".

[0055] The connecting structure 3 can be plugged, screwed or connected in other simple detachable manners with the control cover 1 and / or the electrical cabinet. The embodiment is not limited in the specific connecting manner, as long as the connecting structure 3 can be connected and disconnected with the control cover 1 and / or the electrical cabinet by simple human operation. Since the grid cover 2 is fixed by the connecting structure 3, when the fan assembly inside the electrical cabinet is maintained, the grid cover 2 can be removed by disconnecting the connecting structure 3, without the need to remove the control cover 1, thereby improving the maintenance efficiency.

[0056] The decorative plate 4 is arranged at the outer side of the grid cover 2, and an identification or a trademark can be arranged thereon. The inner extension structure 5 of the decorative plate 4 penetrates the grid cover 2 and is connected with the connecting structure 3. Specifically, when the grid cover 2 is disassembled, the connecting structure 3 can be moved by moving the decorative plate 4, so that the connecting structure 3 is connected or disconnected with the control cover 1 and / or the electrical cabinet; or the decorative plate 4 can be removed from the grid cover 2 first, so that the connecting structure 3 is exposed, and then the connecting structure 3 is connected or disconnected with the control cover 1 and / or the electrical cabinet by human operation.

[0057] Compared with the prior art, the cover assembly provided by the utility model is characterized in that the grid cover 2 is spliced with the control cover 1, and can block the front opening surface of the electrical cabinet; the inner side of the grid cover 2 is provided with the connecting structure 3, the connecting structure 3 is detachably connected with the control cover 1 and / or the electrical cabinet, the decorative plate 4 is provided with the inner extension structure 5 and connected with the connecting structure 3; when the fan assembly inside the electrical cabinet needs to be maintained, the grid cover 2 can be removed by moving the decorative plate 4, moving the inner extension structure 5 or operating the connecting structure 3, so that the connecting structure 3 is separated from the electrical cabinet and / or the control cover 1, without the need to disconnect the electrical connection between the control cover 1 and the electronic control element, thereby improving the disassembly efficiency.

[0058] In some embodiments, the connecting structure 3 can adopt the structure as shown in Figures 1 to 5 , and as shown in Figures 1 to 5 , the connecting structure 3 comprises a lock buckle 31. The lock buckle 31 is arranged in the splicing direction of the control cover 1 and the grid cover 2; the first end of the lock buckle 31 penetrates the grid cover 2, and the second end is connected with the inner extension structure 5; and the lock buckle 31 is further connected with an elastic reset member 32.

[0059] The decorative plate 4 has a first position and a second position. In the first position, the inner extension structure 5 abuts against the second end of the lock catch 31 to push the first end of the lock catch 31 to abut against the control surface cover 1 or the electrical shell. In the second position, the inner extension structure 5 is separated from the second end of the lock catch 31, and the elastic reset member 32 drives the lock catch 31 to move, so that the first end of the lock catch 31 is separated from the control surface cover 1 or the electrical shell.

[0060] Preferably, the lock catch 31 is a long strip structure, which is hidden in the middle part of the grating surface cover 2 and does not affect the air inlet of the grating surface cover 2. The first end and the second end of the lock catch 31 are two ends in the length direction. The first end penetrates through the grating surface cover 2 and is used for being inserted into the control surface cover 1 or the electrical shell. The second end is used for abutting against the inner extension structure 5.

[0061] After the grating surface cover 2 is assembled, the decorative plate 4 is in the first position. At this time, the inner extension structure 5 abuts against the second end of the lock catch 31, and the first end of the lock catch 31 is inserted into the splicing end surface of the control surface cover 1 or the electrical shell, so as to ensure that the grating surface cover 2 is stable in the assembled state. At the same time, the elastic reset member 32 is compressed and stores energy.

[0062] When the grating surface cover 2 needs to be disassembled, the decorative plate 4 is manually moved to the second position. At this time, the inner extension structure 5 is separated from the second end of the lock catch 31, the elastic reset member 32 releases energy, drives the lock catch 31 to move away from the control surface cover 1 / electrical shell, and the second end is no longer inserted. The grating surface cover 2 loses the limiting, and can be disassembled.

[0063] When the grating surface cover 2 is installed again, the grating surface cover 2 is first buckled on the opening surface, and then the decorative plate 4 is moved to the first position. The inner extension structure 5 moves to abut against the second end of the lock catch 31, and the first end of the lock catch 31 is inserted into the splicing end surface of the control surface cover 1 or the electrical shell again.

[0064] It should be noted that the switching path of the first position and the second position can be movement in the inward and outward directions, or rotation about the inward and outward directions as the axis. The embodiment does not limit the specific movement mode of the decorative plate 4, as long as the inner extension structure 5 can abut against and be separated from the second end.

[0065] In addition, the elastic reset member 32 can be arranged between the grating surface cover 2 and the lock catch 31, or arranged on the control surface cover 1 / electrical shell. The elastic reset member 32 can be a spring, a spring sheet, or other elastic members with linear elastic freedom.

[0066] The embodiment adopts the insertion mode of the lock catch 31 to connect the grating surface cover 2 and the control surface cover 1 / electrical shell. The disassembly and assembly operation mode of the grating surface cover 2 is simple, and the lock catch 31 and the inner extension structure 5 are hidden in the inner side of the grating surface cover 2, which does not affect the appearance of the electrical equipment.

[0067] Please refer to Figure 2 and Figure 3 , preferably, on the basis of the above embodiment, the connecting structure 3 is provided with two groups, and is respectively located at two sides of the inner extension structure 5; in the first position, one group of the locking buckles 31 is in contact with the control surface cover 1, and the other group of the locking buckles 31 is in contact with the electrical shell.

[0068] The locking buckles 31 are provided with two groups, and each of the locking buckles 31 is respectively connected with an elastic reset member 32. The two groups of the locking buckles 31 are respectively inserted with the control surface cover 1 and the electrical shell, so that both ends of the grating surface cover 2 can be fixed, thereby improving the fixing stability of the grating surface cover 2 and avoiding the edge of the grating surface cover 2 from being warped.

[0069] It should be noted that, since the two groups of the locking buckles 31 are respectively located at two sides of the inner extension structure 5, in the first position, the inner extension structure 5 is in contact with the first ends of the two groups of the locking buckles 31 at the same time; in addition, in the second position, the inner extension structure 5 is separated from the two groups of the locking buckles 31 at the same time.

[0070] In some embodiments, the above-mentioned inner extension structure 5 can adopt the structure as shown in Figure 5 , referring to Figure 5 , the inner extension structure 5 includes a rotating block 51. The outer circumferential surface of the rotating block 51 is provided with a triangular-shaped protrusion 52; in the first position, the tip of the protrusion 52 is in contact with the first end of the locking buckle 31.

[0071] It should be noted that, if the two sides of the inner extension structure 5 are respectively provided with the locking buckles 31, the protrusion 52 needs to be provided with at least two groups (and the number is even), and is distributed along the circumferential direction of the rotating block 51 at equal intervals.

[0072] By rotating the rotating block 51, that is, rotating the decorative plate 4, the tip of the protrusion 52 can be in contact with or separated from the first end of the locking buckle 31. That is, the switching path of the first position and the second position is the rotation with the inside-outside direction as the axis.

[0073] Preferably, the decorative plate 4 is a rectangular plate, and when the decorative plate 4 is rotated, since the right-angle position changes, the rotating position of the decorative plate 4 can be clearly observed, that is, the operator can clearly know the position of the decorative plate 4, that is, whether the protrusion 52 is in contact with the first end of the locking buckle 31, so as to avoid misoperation. In addition, compared with moving the decorative plate 4 along the inside-outside direction, the rotating mode of the decorative plate 4 can also avoid the decorative plate 4 from being pulled away from the grating surface cover 2 and lost.

[0074] In some embodiments, the above-mentioned inner extension structure 5 can also adopt the structure as shown in Figure 5 , referring to Figure 5The inner extension structure 5 further comprises a connecting sleeve 53. One end of the connecting sleeve 53 is connected to the inner side of the decorative plate 4, and the other end passes through the grating cover 2. The rotating block 51 is partially embedded in the connecting sleeve 53, and the protruding block 52 is located outside the connecting sleeve 53.

[0075] The rotating block 51 is inserted into the connecting sleeve 53, and preferably, the two are in interference fit. When the decorative plate 4 is initially assembled, the connecting sleeve 53 passes through the grating cover 2 from the outside to the inside, and the rotating block 51 is inserted into the connecting sleeve 53 from the inner side of the grating cover 2.

[0076] Since the rotating block 51 is provided with a triangular protruding block 52, the outer diameter of the rotating block 51 is relatively large. By inserting the rotating block 51 into the connecting sleeve 53, when the decorative plate 4 is assembled, the connecting sleeve 53 only needs to pass through the grating cover 2, and accordingly, the size of the opening of the grating cover 2 is reduced, and the decorative plate 4 can completely cover the opening, thereby ensuring the aesthetic performance of the grating cover 2.

[0077] In some embodiments, the above-mentioned connecting structure 3 can adopt the structure as shown in Figures 6 to 10 , and as shown in Figures 6 to 10 , the connecting structure 3 comprises a fixing sleeve 33 and a fastener 34. The fixing sleeve 33 is formed on the inner side of the grating cover 2. The fastener 34 is embedded in the fixing sleeve 33, and one end of the fastener 34 passes through the fixing sleeve 33 and is detachably connected to the electrical shell.

[0078] The fixing sleeve 33 extends inwardly along the inner and outer directions of the grating cover 2, and preferably, the end surface of the fixing sleeve 33 abuts against the opening surface of the electrical shell. The fixing sleeve 33 has an inner cavity, and the fastener 34 is hidden in the inner cavity, and preferably, the fastener 34 is a threaded fastener 34.

[0079] The inner extension structure 5 extends into the inner cavity of the fixing sleeve 33, and the decorative plate 4 can cover the fixing sleeve 33 and the fastener 34. When the grating cover 2 needs to be disassembled, the decorative plate 4 is first removed to expose the fixing sleeve 33, and then the fastener 34 is unscrewed using a tool, and the grating cover 2 can be disassembled. When the grating cover 2 is installed, the fastener 34 is first screwed onto the electrical shell using a tool, and then the inner extension structure 5 is embedded in the fixing sleeve 33.

[0080] Since the fastener 34 is hidden in the fixing sleeve 33, and the fixing sleeve 33 is covered by the decorative plate 4, it can not only avoid the loss of the fastener 34 and the inability to lock the grating cover 2, but also will not occupy the outer side space of the grating cover 2, thereby improving the aesthetic performance of the grating cover 2.

[0081] In some embodiments, the above-mentioned inner extension structure 5 can adopt the structure as shown in Figure 8 and Figure 10 , and as shown in Figure 8 and Figure 10The inner extension structure 5 comprises a plurality of clamping blocks 54. The plurality of clamping blocks 54 are equidistantly distributed along the circumference of the fixing sleeve 33; one end of each clamping block 54 is connected to the inner side of the decorative plate 4, and the other end is a free end; the free ends of the plurality of clamping blocks 54 are clamped in the inner cavity of the fixing sleeve 33.

[0082] It should be noted that there is a space between each adjacent two clamping blocks 54. One end of each clamping block 54 is fixed, and the other end is free, that is, each clamping block 54 has a slight deformation. Before inserting the inner extension structure 5 into the fixing sleeve 33, a few clamping blocks 54 can be manually pinched to reduce the dimension enclosed by the plurality of clamping blocks 54, so as to be easily inserted into the fixing sleeve 33. After the pinching force disappears, the clamping blocks 54 return to the original position and are tightly expanded in the inner cavity of the fixing sleeve 33, thereby ensuring the stable assembly of the decorative plate 4. When disassembling the decorative plate 4, the artificial pulling force can overcome the expansion force of the plurality of clamping blocks 54, so that the decorative plate 4 can be smoothly disassembled.

[0083] Preferably, referring to Figure 9 and Figure 10 , on the basis of the above-mentioned embodiments, the inner circumferential wall of the fixing sleeve 33 is provided with an arc-shaped limiting surface 331 recessed radially inward, and the free ends of the at least two clamping blocks 54 are provided with clamping hooks 541 protruding radially outward; the clamping hooks 541 are equidistantly distributed along the circumference of the fixing sleeve 33 and abut the arc-shaped limiting surface 331 in the inner-outer direction of the grating cover 2.

[0084] The arc-shaped limiting surface 331 is similar to a stepped surface and is arranged around the inner circumferential wall of the fixing sleeve 33. In the radial direction of the fixing sleeve 33, the arc-shaped limiting surface 331 is recessed inward and is an arc surface. Alternatively, it can be understood that the inner circumferential wall of the fixing sleeve 33 is divided into a first part and a second part which are sequentially connected in the axial direction; the first part is close to the outer side of the grating cover 2, and the inner diameter of the first part is smaller than that of the second part; and the arc-shaped limiting surface 331 is a fillet transition surface between the first part and the second part.

[0085] The clamping hooks 541 abut the arc-shaped limiting surface 331 in the inner-outer direction of the grating cover 2, which can further limit the inner-outer direction of the decorative plate 4 after the decorative plate 4 is installed, thereby ensuring the stable state of the decorative plate 4. In addition, when disassembling the decorative plate 4, the arc-shaped limiting surface 331 is not a plane, and under the condition of artificial force, the clamping hooks 541 can be separated from the arc-shaped limiting surface 331, so that the decorative plate 4 can be smoothly disassembled.

[0086] In some embodiments, the above-mentioned grating cover 2 can also adopt the structures shown in Figure 2 , Figure 3 and Figure 7 , referring to Figure 2 , Figure 3 and Figure 7 Figure 7The inner side of the grating cover 2 is provided with an elastic pushing piece 21, which abuts against the front end opening surface of the electrical shell.

[0087] The elastic pushing piece 21 is arranged between the grating cover 2 and the opening surface and stores elastic energy.

[0088] Based on the same inventive concept, the embodiment of the present application also provides an electrical equipment comprising an electrical shell and the above-mentioned cover assembly.

[0089] The electrical shell is generally hexahedral in shape and comprises two side plates, a bottom plate, a top plate and a back plate.

[0090] It should be noted that the above-mentioned opening surface is the front end surface of the electrical shell because the fan assembly is generally installed on the air inlet side of the electrical device and because the control cover 1 is oriented forward to facilitate human operation.

[0091] The electrical equipment provided by the present application can conveniently disassemble and assemble the grating cover 2 and improve the maintenance operation efficiency of the electrical equipment.

[0092] The above-mentioned is only a preferred embodiment of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
