[0031] As described in the background art, the inverter shielding covers of the prior art usually adopt an integrally formed structure or a snap-type structure. The integrally formed inverter shielding cover is not detachable or foldable, and will occupy a large space during storage. The snap-type inverter shielding cover has a risk of damage during assembly or disassembly, and has low stability. Therefore, the present application provides a shielding device and an inverter having the shielding device. The shielding device can achieve two states of folding and opening through a rotary folding structure without disassembly, can reduce the occupied space during transportation and storage, and does not require disassembly or assembly, and has high stability. The shielding device of the present utility model will be introduced and described in detail below with reference to the drawings.

[0032] See Figures 1 to 5 As shown, the shielding device in this embodiment includes a main shielding member 10, a first auxiliary shielding member 20, and a second auxiliary shielding member 30. Among them, the main shielding member 10 includes a first end 11 and a second end 12 that are oppositely arranged. The first auxiliary shielding member 20 is rotatably connected to the first end 11 of the main shielding member 10, and the second auxiliary shielding member 30 is rotatably connected to the second end 12 of the main shielding member 10. When the first auxiliary shielding member 20 and the second auxiliary shielding member 30 are rotatably connected to the main shielding member, they are both located on the first side surface 13 of the main shielding member 10. The first auxiliary shielding member 20 and the second auxiliary shielding member 30 respectively have an open state of rotating outward from the main shielding member 10 at a preset angle, and the first auxiliary shielding member 20 and the second auxiliary shielding member 30 also respectively have a folded state of rotating inward to the main shielding member 10 and fitting with the main shielding member 10.

[0033] Since the first auxiliary shielding member 20 and the second auxiliary shielding member 30 of the shielding device in this embodiment are rotatably connected to both ends of the main shielding member 10 in a rotary folding structure, the rotary folding structure of the shielding device can achieve two states: folding and opening. When the shielding device needs to be transported or stored, rotate the first auxiliary shielding member 20 and the second auxiliary shielding member 30 to the folded state and then store or transport them, which can reduce the space occupied by the shielding device and lower the transportation cost. When the shielding device needs to shield the wiring terminals of the inverter, rotate the first auxiliary shielding member 20 and the second auxiliary shielding member 30 to the open state and then install them on the inverter to shield the wiring terminals of the inverter, without the need to disassemble and reassemble the main shielding member 10, the first auxiliary shielding member 20, and the second auxiliary shielding member 30, improving the stability of the shielding device.

[0034] Specifically, the first auxiliary shielding member 20 is rotatably connected to the first end 11 through the first connecting member 21, and the second auxiliary shielding member 30 is rotatably connected to the second end 12 through the second connecting member 31.

[0035] In this embodiment, the first auxiliary shielding member 20 is rotatably connected to the first end 11 of the main shielding member 10 through the first connecting member 21, and the second auxiliary shielding member 30 is rotatably connected to the second end 12 of the main shielding member 10 through the second connecting member 31, which can realize the relative rotation between the first auxiliary shielding member 20 and the second auxiliary shielding member 30 and the main shielding member 10, so that the first auxiliary shielding member 20 and the second auxiliary shielding member 30 can have two states of folding and opening, improving the convenience of storing the shielding device. After folding the first auxiliary shielding member 20 and the second auxiliary shielding member 30, the shielding device is stored or transported, reducing the required space and transportation cost.

[0036] Specifically, the first end 11 of the main shielding member 10 is provided with a first positioning hole 111. The first connecting member 21 includes a first screw 211. At least part of the first screw 211 is inserted into the first positioning hole 111. The first connecting member 21 is provided with a first connecting hole 212. The first auxiliary shielding member 20 is rotatably sleeved on the first screw 211 through the first connecting hole 212.

[0037] In other embodiments of the present application, the connection structure between the first end 11 of the main shielding member 10 and the first connecting member 21 can also be a rotatable structure such as a shaft connection, a hinge connection, a bearing connection, etc. As long as it is other deformation methods under the concept of the present application, they are all within the protection scope of the present application.

[0038] In this embodiment, by arranging the first screw 211 to be at least partially inserted into the first positioning hole 111 of the main shielding member 10, and the first auxiliary shielding member 20 is rotatably sleeved on the first screw 211 through the first connection hole 212, the first auxiliary shielding member 20 can be rotatably fixed to the first end 11 of the main shielding member 10. When the first auxiliary shielding member 20 is rotated to the folded state through the first connection hole 212 and the first screw 211, a threaded connection is formed between the first screw 211 and the first positioning hole 111. By tightening the first screw 211, it is possible to prevent the first auxiliary shielding member 20 from loosening when in the folded state, improving the stability of the shielding device.

[0039] Similarly, a second positioning hole 121 is provided at the second end 12 of the main shielding member 10. The second connecting member 31 includes a second screw 311. The second screw 311 is at least partially inserted into the second positioning hole 121. A second connection hole 312 is provided on the second connecting member 31. The second auxiliary shielding member 30 is rotatably sleeved on the second screw 311 through the second connection hole 312.

[0040] In this embodiment, by arranging the second screw 311 to be at least partially inserted into the second positioning hole 121 of the main shielding member 10, and the second auxiliary shielding member 30 is rotatably sleeved on the second screw 311 through the second connection hole 312, the second auxiliary shielding member 30 can be rotatably fixed to the second end 12 of the main shielding member 10. When the second auxiliary shielding member 30 is rotated to the folded state through the second connection hole 312 and the second screw 311, a threaded connection is formed between the second screw 311 and the second positioning hole 121. By tightening the second screw 311, it is possible to prevent the second auxiliary shielding member 30 from loosening when in the folded state, improving the stability of the shielding device.

[0041] In other embodiments of the present application, the connection structure between the second end 12 of the main shielding member 10 and the second connecting member 31 can also be a rotatable structure such as a shaft connection, a hinge connection, a bearing connection, etc. Moreover, the connection structure between the first end 11 of the main shielding member 10 and the first connecting member 21, and the connection structure between the second end 12 of the main shielding member 10 and the second connecting member 31 can be arbitrarily combined with different connection structures. As long as it is other deformation methods under the concept of the present application, they are all within the protection scope of the present application.

[0042] Furthermore, a first limiting component 22 is provided between the first auxiliary shielding member 20 and the first end 11 of the main shielding member 10. The first limiting component 22 is used to limit the first auxiliary shielding member 20 to the open state; and / or, a second limiting component is provided between the second auxiliary shielding member 30 and the second end 12 of the main shielding member 10. The second limiting component is used to limit the second auxiliary shielding member 30 to the open state.

[0043] In this embodiment, the first limiting component 22 and the second limiting component can respectively limit the first auxiliary shielding member 20 and the second auxiliary shielding member 30 in the open state, which can ensure that the first auxiliary shielding member 20 and the second auxiliary shielding member 30 remain stable when in the open state, so that the first auxiliary shielding member 20 and the second auxiliary shielding member 30 will not rotate due to external interference, and the stability of the overall structure of the shielding device is improved.

[0044] Specifically, the first limiting component 22 includes a first hook 221 and a first slot 222. One of the first hook 221 and the first slot 222 is arranged on the first auxiliary shielding member 20, and the other is arranged at the first end 11 of the main shielding member 10. That is to say, when the first hook 221 in this embodiment is arranged on the first auxiliary shielding member 20, the first slot 222 is arranged at the first end 11 of the main shielding member 10; when the first hook 221 in this embodiment is arranged at the first end 11 of the main shielding member 10, the first slot 222 is arranged on the first auxiliary shielding member 20.

[0045] Furthermore, the second limiting component includes a second hook 321 and a second slot. One of the second hook 321 and the second slot is arranged on the second auxiliary shielding member 30, and the other is arranged at the second end 12 of the main shielding member 10. That is to say, when the second hook 321 in this embodiment is arranged on the second auxiliary shielding member 30, the second slot is arranged at the second end 12 of the main shielding member 10; when the second hook 321 in this embodiment is arranged at the second end 12 of the main shielding member 10, the second slot is arranged on the second auxiliary shielding member 30.

[0046] In this embodiment, through the cooperation of the first hook 221 and the first slot 222, when the first auxiliary shielding member 20 is in the open state, the first hook 221 is snapped into the first slot 222 to keep the first auxiliary shielding member 20 in the open state all the time. Through the cooperation of the second hook 321 and the second slot, when the second auxiliary shielding member 30 is in the open state, the second hook 321 is snapped into the second slot to keep the second auxiliary shielding member 30 in the open state all the time. A stable locking mechanism is provided for the first auxiliary shielding member 20 and the second auxiliary shielding member 30 when in the open state, so that there is a stable fixing force between the first end 11 of the main shielding member 10 and the first auxiliary shielding member 20, and between the second end 12 of the main shielding member 10 and the second auxiliary shielding member 30, which can prevent the first auxiliary shielding member 20 and the second auxiliary shielding member 30 from accidentally folding due to external forces, and ensure the stability of the shielding device during use.

[0047] Specifically, connection portions 230 are provided on both the first auxiliary shielding member 20 and the second auxiliary shielding member 30. The connection portions 230 are used to connect to a predetermined structure. The predetermined structure in this embodiment may be an inverter or other structures having terminal blocks.

[0048] In this embodiment, by respectively providing connection portions 230 on the first auxiliary shielding member 20 and the second auxiliary shielding member 30 for connecting to the terminal blocks of the inverter or other predetermined structures having terminal blocks, the first auxiliary shielding member 20 and the second auxiliary shielding member 30 can be connected to the inverter through separate connection portions, thereby not affecting the shielding ranges of the main shielding member 10, the first auxiliary shielding member 20, and the second auxiliary shielding member 30, and improving the shielding effect of the shielding device.

[0049] Specifically, both the first auxiliary shielding member 20 and the second auxiliary shielding member 30 are provided in a long strip shape. The connection portion 230 includes an extension section 231. The extension section 231 extends in a direction perpendicular to the corresponding first auxiliary shielding member 20 and second auxiliary shielding member 30, and threaded holes 2311 are provided on the extension section 231.

[0050] In this embodiment, by providing the extension section 231 in the connection portion 230, the connection between the connection portion 230 and the inverter or other structures having terminal blocks can be made more stable. The extension section 231 increases the connection area and improves the shear and tensile resistance of the connection. Through the threaded holes 2311, bolts or other fasteners can be used to fix the shielding device. The mechanical connection method is more reliable than simple buckling or bonding, can withstand greater external forces, improves the stability of the shielding device, and facilitates the disassembly and replacement of the shielding device.

[0051] On the other hand, the present application also discloses an inverter, which includes the above-mentioned shielding device. Therefore, this inverter includes all the technical effects of the above-mentioned shielding device. Since the technical effects of the shielding device have been described in detail above, they will not be repeated here.

[0052] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations for the spatial relative descriptions used herein will be made accordingly.

[0053] In addition, it should be noted that the use of terms such as "first" and "second" to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present utility model.

[0054] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and variations.
