Description

Technical Field

[0001] The utility model relates to the technical field related to power electronic device shells, in particular to a control panel shell with a patch and an electromagnetically shielded control panel device. Background Art

[0002] At present, for the installation and use of EMU control boards in the control systems of the energy storage industry, the conventional practice is to install the control board in a dedicated metal casing, and then install the metal casing in a cabinet or sell it directly to improve convenience and have better electromagnetic shielding and other protection functions.

[0003] However, the use of this type of control board is rather special. Whether to use multiple interfaces depends on different scenarios, and these interfaces also have high requirements for electromagnetic shielding. When a certain interface is not used, this interface is not allowed to be exposed outside the metal shell, that is, the metal shell is not allowed to have openings. If multiple metal shells with different openings are made according to various usage scenarios, on the one hand, versatility will be affected, and on the other hand, due to the uncertainty of whether certain interfaces will be used, it is impossible to make the correct selection in advance. For example, if a certain interface needs to be added in the later stage to increase the use of functions, since there was no opening left in the corresponding position of the metal shell before, the metal shell model needs to be replaced. In actual operation, the feasibility is not high. Utility Model Content

[0036] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation methods and the accompanying drawings.

[0037] Please refer to Figures 1 to 3 , the utility model provides a technical solution: a control panel housing with a patch, comprising an outer cover, a bottom shell and a patch;

[0038] The outer cover is fixedly connected to the bottom shell, and the patch is arranged between the outer cover and the bottom shell, and is fixedly connected to the outer cover and the bottom shell;

[0039] The outer cover is provided with a bent portion with a downwardly turned edge, and the bent portion is provided with notches corresponding to the control panel interfaces one by one;

[0040] The patch is provided with a pre-opening corresponding to the notch, and a detachable blocking piece is provided at the pre-opening.

[0041] From the above description, it can be seen that the beneficial effect of the utility model is that by adding a patch to the shell and cutting a conveniently removable baffle on the patch in advance with laser, it not only ensures convenient operation during factory testing, but also ensures electromagnetic shielding of the later interface. And if it is necessary to add a certain interface in certain scenarios, it is only necessary to remove the corresponding baffle, which meets the needs of different usage scenarios.

[0042] Furthermore, a cutting seam is provided between the edge of the pre-opening and the blocking piece;

[0043] The blocking piece is connected to the edge of the pre-opening by breaking off.

[0044] From the above description, it can be known that by reserving the broken end, the cutting seam is not completely connected, the baffle is connected to the broken end and will not fall off, but is still connected to the patch, thereby protecting the control board interface.

[0045] Furthermore, the broken end is arranged on the horizontal midline of the baffle, on the vertical midline of the baffle, or on the horizontal midline and the vertical midline of the baffle.

[0046] From the above description, it can be seen that the broken end can be set on the horizontal center line of the baffle, the vertical center line of the baffle, or the horizontal center line and vertical center line of the baffle. When necessary, the baffle can be removed by slightly rotating the baffle along the broken end, which is convenient for the selection of subsequent interfaces.

[0047] Furthermore, the cutting slit width is 0.1-0.6 mm;

[0048] The length of the broken end is 0.3-0.9 mm, and the width corresponds to the cutting seam.

[0049] From the above description, it can be seen that the width of the cutting seam takes into account the protection performance of the patch while also facilitating the removal of the baffle when the interface is used as needed later; the reserved broken end length is moderate, which not only prevents the cutting seam from being connected, but also ensures that the baffle will not fall off.

[0050] Furthermore, the bottom shell is provided with an upward bending portion.

[0051] From the above description, it can be seen that the control board is installed above the bending part, which raises the height of the control board interface position, facilitates the use of subsequent interfaces, reduces the impact on the plugging and unplugging of the connector, and also plays a role in fixing the patch.

[0052] Furthermore, a convex edge is provided outwardly at the right end of the bottom shell, and a leaking portion is provided on the convex edge.

[0053] It can be seen from the above description that the flange design facilitates the installation and fixation of the control panel housing in a cabinet or other usage scenario.

[0054] Furthermore, the outer cover, the bottom shell and the patch are all provided with fixing holes.

[0055] It can be seen from the above description that the three are fixedly connected to form a whole through the fixing hole piece, which improves the strength and electromagnetic shielding capability of the shell.

[0056] Furthermore, the outer cover, the bottom shell and the patch are all made of cold-rolled steel plates with a thickness of 1-3 mm.

[0057] From the above description, it can be seen that the selection of cold-rolled steel plates with a thickness of 1-3 mm improves the strength and stability of the overall structure while ensuring the electromagnetic shielding capability of the device.

[0058] Furthermore, the surface of the cold-rolled steel sheet is subjected to electrophoresis treatment.

[0059] It can be seen from the above description that the corrosion resistance of the surface of the cold-rolled steel sheet is effectively improved.

[0060] On the other hand, the utility model provides an electromagnetically shielded control panel device, including a control panel and a control panel housing, wherein the control panel housing adopts the control panel housing with a patch as described above;

[0061] The control board is arranged inside the housing.

[0062] The utility model is applied to the installation and use of EMU control panels and the like in the control systems of the energy storage industry, meeting the needs of different usage scenarios.

[0063] Please refer to Figure 1-4 , the first embodiment of the present invention is:

[0064] A control panel 20 housing with a patch 3 comprises an outer cover 1, a bottom shell 2 and a patch 3.

[0065] like Figure 3 As shown, the patch 3 is provided with a pre-opening corresponding to the notch 18, a detachable baffle 4 is provided at the pre-opening, a cutting seam 5 is provided between the edge of the pre-opening and the baffle 4, and a broken end 6 is located on the horizontal midline of the baffle 4, so that the cutting seam 5 is not connected, the baffle 4 will not fall off, and is connected to the patch 3 through the broken end 6.

[0066] like Figure 1 and Figure 2 As shown, the outer cover 1 is fixed to the bottom shell 2 through the fixing hole 9. The outer cover 1 has a downwardly turned bend 17, the length of which basically covers the interface position of the control board 20, and a corresponding notch 18 is left. The notch 18 corresponds to the interface on the control board 20 one by one, which is convenient for plugging and unplugging. A fixing hole 9 for fixing the patch 3 is opened at the upper part. The bottom shell 2 is provided with an upward bend 19, the height of which is close to the control board 20, and a fixing hole 9 for fixing the patch 3 is also left.

[0067] The upper part of the patch 3 is fixed to the outer cover 1 through the fixing hole piece 9 on the downwardly turned bend portion 17, and the lower part is fixed to the bottom shell 2 through the fixing hole piece 9 on the upwardly turned bend portion 19. At the same time, the patch also plays a role in connecting the outer cover 1 and the bottom shell 2. The right end of the bottom shell 2 is provided with a convex edge 7, and the convex edge 7 is provided with a leaking portion 8.

[0068] Please refer to Figures 1 to 5 , Embodiment 2 of the present utility model is:

[0069] In this embodiment, if Figure 1 , Figure 2 and Figure 5 As shown, an electromagnetic shielding control panel 20 device includes a control panel 20 and a control panel 20 housing. The control panel 20 housing adopts a control panel 20 housing with a patch 3 in the first embodiment. The control panel 20 is arranged above the bottom shell 2 and is fixedly connected to the outer cover 1 and the bottom shell 2. All components are made of 1mm thick cold-rolled steel plates, and the surface is electrophoretically treated.

[0070] In this embodiment, if Figure 5 As shown, the control board 20 has 5 interfaces. In some scenarios, except for interface 5 (14) which is always used, the other 4 interfaces are used according to the situation. Among them, interface 4 (13) is only used during factory debugging. Interface 1 (10), interface 2 (11), and interface 3 (12) are used in the debugging stage. In the later stage, whether to use them depends on different usage scenarios. When debugging or program burning is required, by removing patch 3, Figure 2 As shown, the corresponding interfaces are exposed, and corresponding operations can be performed.

[0071] In this embodiment, if Figure 3 As shown, since the interface 4 (13) is no longer used after debugging, it is shielded and no pre-opening is reserved. At the positions corresponding to the interfaces 1 (10), 2 (11), and 3 (12) on the patch 3, a cutting slit 5 with a width of about 0.3 mm is cut out according to the required size of the corresponding interface by laser cutting technology, and a pre-opening is performed. On the horizontal midline of the baffle 4, a broken end 6 with a length of about 0.6 mm is reserved so that the cutting slit 5 is not connected. In this way, the baffle 4 will not fall off and is still connected to the patch 3.

[0072] like Figure 3 and Figure 4 As shown, when a certain interface needs to be used, the pre-cut baffle 4 can be removed at the corresponding interface position on the patch 3, such as by cutting off a broken end 6 with diagonal pliers and then turning the baffle 4 outward, or removing the patch 3 and slightly rotating it along the center broken end 6 to expose the interface for operation. After removing the baffle 4, since the broken end 6 protrudes outward by about 0.3-0.5mm, the burr 15 generated does not exceed this spacing and reach the interface plane 16, and does not interfere with plugging and unplugging.

[0073] In summary, the control panel housing with a patch provided by the utility model not only ensures convenient operation during factory testing, but also ensures electromagnetic shielding of the later interface by adding a patch to the housing and pre-cutting a removable baffle on the patch with laser. Moreover, if a certain interface needs to be added in certain scenarios, only the corresponding baffle needs to be removed, thus meeting the needs of different usage scenarios.

[0074] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
