[0031] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0032] As mentioned above, inverters in related technologies lack protection for their terminals. Specifically, during inverter operation, the terminals are easily pulled out accidentally or maliciously, leading to serious consequences and posing a significant safety hazard. Therefore, this application provides an inverter chassis that incorporates an adjustable protection device to protect the terminals, effectively reducing the possibility of them being pulled out during inverter operation and thus improving inverter safety.

[0033] Figure 1 This is a first schematic diagram of a portion of the inverter chassis in one embodiment of this application; Figure 2 This is a second schematic diagram of a portion of the inverter chassis in one embodiment of this application; Figure 3 This is a schematic diagram illustrating the interaction between the inverter chassis and the terminal block 500 in one embodiment of this application. Figures 1 to 3 As shown, the inverter chassis of this embodiment includes a chassis and a protective device 200 disposed within the chassis. The chassis is used to house the functional modules of the inverter, such as circuit boards and DC circuit breakers. The chassis includes a side panel assembly 100 for forming a receiving cavity. The side panel assembly 100 is one of the components for forming the receiving cavity of the chassis. In this embodiment, the chassis also includes a bottom plate 300, a protective plate 400, and other parts for forming the receiving cavity. It should be understood that other plates used to compose the chassis are not included in this embodiment. Figure 1 , Figure 2 As shown in the example, the enclosure may also include a plate opposite to the bottom plate 300 and a plate opposite to the side plate assembly 100, so that all six sides of the cuboid enclosure are protected.

[0034] Figure 4 for Figure 1 Enlarged view of local IV in the middle, such as Figures 1 to 4 As shown in this embodiment, the side panel assembly 100 is provided with mounting holes 122 for inserting terminal blocks 500. In this embodiment, the terminal blocks 500 are used to connect functional modules in the inverter chassis, and then connect to external devices (such as energy storage devices, electrical equipment, power grid, etc.) via cables.

[0035] The protection device 200 comprises an adjusting member 210 and a blocking member 240, the blocking member 240 is movably arranged on the side plate assembly 100, the blocking member 240 has a locking position and an unlocking position relative to the side plate assembly 100, when the blocking member 240 is in the locking position, the blocking member 240 can block the wiring terminal 500 from moving outwardly away from the assembly hole 122, when the blocking member 240 is in the unlocking position, the blocking member 240 can avoid the wiring terminal 500 moving outwardly. At least a part of the adjusting member 210 is located outside the box, the adjusting member 210 is in transmission connection with the blocking member 240 to adjust the blocking member 240 to switch between the locking position and the unlocking position. Figure 1 、 Figure 3 In the figure, the blocking member 240 is in the locking position. It can be understood that at least a part of the adjusting member 210 is located outside the box, and the adjusting member 210 is in transmission connection with the blocking member 240, so that the operator can control the position of the blocking member 240 through the adjusting member 210 outside the inverter case, so that the blocking member 240 can be in the locking position or the unlocking position. When the blocking member 240 is in the locking position, the blocking member 240 can block the wiring terminal 500, so that the wiring terminal 500 cannot be pulled out of the side plate assembly 100, reducing the risk of the wiring terminal 500 being accidentally pulled out. When it is necessary to plug or pull the wiring terminal 500, the blocking member 240 is adjusted to the unlocking position by using the adjusting member 210, so that the blocking member 240 does not interfere with the plugging or pulling of the wiring terminal 500, and the operator can plug or pull the wiring terminal 500. It can be seen that the inverter case provided by the embodiment has high safety.

[0036] In some embodiments, the side plate assembly 100 comprises a side plate body 110 and an assembly box 120, the side plate body 110 is provided with a window 111, the assembly box 120 has an opening, the assembly box 120 is connected to the inner side of the side plate body 110, and the opening of the assembly box 120 is opposite to the window 111 of the side plate body 110. The assembly box 120 has a bottom wall 121 opposite to the opening and a side wall 123 connecting the bottom wall 121 and the side plate body 110, the assembly hole 122 is arranged on the bottom wall 121 of the assembly box 120, the side wall 123 of the assembly box 120 is provided with an avoiding hole 124, and at least a part of the blocking member 240 is located on the inner side of the side plate body 110. When the blocking member 240 is in the locking position, the blocking member 240 passes through the avoiding hole 124 so that a part of the blocking member 240 is located in the assembly box 120.

[0037] As Figure 3As shown, in some embodiments, the assembly box 120 further has a slope wall 125, one end of which is connected to the edge of the bottom wall 121 and the other end is connected to the edge of the window 111, the slope wall 125 forms an obtuse angle with the bottom wall 121, so that the slope wall 125 gradually moves away from the terminal 500 in the extension direction from the bottom wall 121 to the window 111. In this way, the cable connected to the terminal 500 can be led out of the assembly box 120 along the slope wall 125.

[0038] In some embodiments, the inner side of the side plate body 110 refers to the side of the side plate body 110 facing the accommodating cavity of the box body. The assembly box 120 is connected to the inner side of the side plate body 110, and the opening of the assembly box 120 is opposite to the window 111 of the side plate body 110, so that the operator can install the terminal 500 into the assembly box 120 through the window 111 of the side plate body 110 on the outer side of the side plate body 110. In the present embodiment, the bottom wall 121 of the assembly box 120 is provided with two assembly holes 122, which can be used to arrange two terminals 500 (such as positive and negative terminals). Since the side wall 123 of the assembly box 120 is provided with the avoiding hole 124, the blocking piece 240 located on the inner side of the side plate body 110 can extend into the assembly box 120 through the avoiding hole 124, and then move to the locking position to block and position the terminal 500.

[0039] Figure 5 For Figure 2 An enlarged view of the partial V. In combination with Figures 1 to 5 In some embodiments, the side plate body 110 is provided with a plug hole, and the adjusting piece 210 is inserted into the plug hole and can rotate relative to the plug hole. The adjusting piece 210 includes an adjusting part 211 and a transmission shaft 213, the adjusting part 211 is located on the outer side of the side plate body 110, and the end of the transmission shaft 213 away from the adjusting part 211 is located on the inner side of the side plate body 110, and the transmission shaft 213 is drivingly connected with the blocking piece 240 through the transmission assembly. In at least one embodiment, the adjusting part 211 is a rotating handle, which is convenient for the operator to hold and rotate, and when the adjusting part 211 rotates, the transmission shaft 213 can synchronously rotate around its own axis. In other embodiments, the specific shape of the adjusting part 211 can also be adjusted, such as a polygonal knob or a knob with damping lines on the outer periphery.

[0040] Further, the adjusting piece 210 further includes a plug part 212, which is plugged and matched with the plug hole and can rotate relative to the plug hole, and the adjusting part 211, the plug part 212 and the transmission shaft 213 are connected in sequence in the extension direction of the rotation axis of the adjusting piece 210.

[0041] In some embodiments, the transmission assembly comprises a first transmission member 220 and a second transmission member 230, the first transmission member 220 is sleeved on the transmission shaft 213 and can rotate with the transmission shaft 213, one end of the second transmission member 230 is rotationally connected with the blocking member 240, and the other end of the second transmission member 230 is rotationally connected with the first transmission member 220. It can be seen that the rotation of the transmission shaft 213 can be converted into the translation of the blocking member 240 through the first transmission member 220 and the second transmission member 230.

[0042] In at least one embodiment, the transmission shaft 213 is a square shaft, and the first transmission member 220 is provided with a square hole matched with the transmission shaft 213. By setting the transmission shaft 213 as a square shaft, the first transmission member 220 can be sleeved on the transmission shaft 213 and rotate with the transmission shaft 213, without or with reduced use of interference fit or bonding, welding and other methods to fixedly connect the first transmission member 220 with the transmission shaft 213, thereby improving the convenience of assembling and disassembling the first transmission member 220. In alternative embodiments, the transmission shaft 213 can also have other non-circular cross sections, such as an elliptical, semicircular or polygonal cross section.

[0043] In some embodiments, the first transmission member 220 and the second transmission member 230 can be connected by screws and nuts to realize relative rotation, and the second transmission member 230 and the blocking member 240 can be connected by screws and nuts to realize relative rotation.

[0044] Further, the transmission assembly further comprises a first limiting member 221, which is arranged on one side of the first transmission member 220 close to the insertion part 212, and is used to abut against the insertion part 212 to limit the first transmission member 220 from approaching the insertion part 212. By arranging the first limiting member 221, the first transmission member 220 can be blocked and limited in one direction, thereby effectively preventing the first transmission member 220 from approaching the insertion part 212 along the axial direction of the transmission shaft 213, so as to avoid the transmission effect of the transmission assembly from being deteriorated.

[0045] In some embodiments, the end of the transmission shaft 213 is used to connect a DC circuit breaker of the inverter, in other words, the rotation of the adjusting member 210 is not only used to switch the blocking member 240 between the unlocked position and the locked position, but also used to open or close the DC circuit breaker. Alternatively, when the blocking member 240 is in the unlocked position, the DC circuit breaker is in a power-off state, and when the blocking member 240 is in the locked position, the DC circuit breaker is in a power-on state. Such an arrangement means that when the DC circuit breaker is powered on, the blocking member 240 can prevent the terminal 500 from being pulled out, thereby ensuring the safety during the operation of the inverter; when the DC circuit breaker is powered off, the blocking member 240 does not block the terminal 500, and at this time, pulling out the terminal 500 will not cause any adverse consequences.

[0046] Further, the transmission assembly further comprises a second limiting member 222, which is arranged on the side of the first transmission member 220 away from the plug-in part 212, and is used to abut against the DC circuit breaker to prevent the first transmission member 220 from approaching the DC circuit breaker. In combination with the first limiting member 221 and the second limiting member 222, the first transmission member 220 can be limited to a proper position on the transmission shaft 213, so as to be in an optimal transmission state. Optionally, the first limiting member 221 and the second limiting member 222 can be fixed on both sides of the first transmission member 220 by means of bolts and nuts.

[0047] Further, in some embodiments, the side plate assembly 100 further comprises a guide rail 130, and the blocking member 240 is in sliding fit with the guide rail 130. By arranging the guide rail 130, the movement path of the blocking member 240 can be effectively limited, so that the blocking member 240 can be translated along a set straight path, and meanwhile the stability of the blocking member 240 in the locked position can be improved, and the blocking member 240 can more effectively block the terminal 500 from being pulled out.

[0048] In at least one embodiment, the blocking member 240 is in a sheet shape, the guide rail 130 is connected to the outer side of the side wall 123 of the assembly box 120, the guide rail 130 forms a channel 131, one end of the channel 131 is in communication with the avoiding hole 124, and the blocking member 240 is inserted into the channel 131 of the guide rail 130. The shape of the channel 131 of the guide rail 130 is matched with the shape of the blocking member 240, so that the guide rail 130 has a good limiting effect on the blocking member 240, and the blocking member 240 can slide along the channel 131 of the guide rail 130.

[0049] The embodiment of the present application also provides an inverter (not shown in the figure), which comprises a functional module and the inverter cabinet provided by the above-mentioned embodiment of the present application, and the functional module is arranged in the cabinet.

[0050] In summary, the inverter cabinet provided by the embodiment of the application comprises a cabinet body and a protection device 200 arranged on the cabinet body. The cabinet body comprises a side plate assembly 100 for enclosing a containing cavity, and the side plate assembly 100 is provided with an assembly hole 122 for inserting a wiring terminal 500. The protection device 200 comprises an adjusting member 210 and a blocking member 240, and the blocking member 240 is movably arranged on the side plate assembly 100. The blocking member 240 has a locking position and an unlocking position relative to the side plate assembly 100. When the blocking member 240 is in the locking position, the blocking member 240 can block the wiring terminal 500 from moving outward away from the assembly hole 122. When the blocking member 240 is in the unlocking position, the blocking member 240 can avoid the wiring terminal 500 moving outward. At least a part of the adjusting member 210 is located outside the cabinet body, and the adjusting member 210 is in transmission connection with the blocking member 240 to adjust the blocking member 240 to switch between the locking position and the unlocking position. By operating the adjusting member 210 outside the inverter cabinet, the adjusting member 210 can be used to adjust the blocking member 240 to be in the locking position or the unlocking position. When the blocking member 240 is in the locking position, the blocking member 240 can block the wiring terminal 500, so that the wiring terminal 500 cannot be pulled out of the side plate assembly 100, and the risk of the wiring terminal 500 being accidentally pulled out is reduced. When it is necessary to plug or unplug the wiring terminal 500, the adjusting member 210 is only needed to adjust the blocking member 240 to the unlocking position, so that the blocking member 240 does not interfere with the plugging or unplugging of the wiring terminal 500, and the operator can plug or unplug the wiring terminal 500. It can be seen that the inverter cabinet provided by the embodiment of the application has high safety.

[0051] The inverter provided by the embodiment of the application comprises the inverter cabinet described above, and therefore has the advantage of high safety.

[0052] The above merely describes the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any changes or replacements that can be easily thought of by those skilled in the art within the technical range disclosed by the present application should be covered within the protection scope of the present application.
