DETAILED DESCRIPTION

[0022] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0024] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0025] One of the preferred embodiments of the present application is as follows: Figures 1 to 6 As shown, a high-protection inverter DC inductor box includes a shell 1, an end cover 2, a plurality of locking blocks 7, a plurality of locking grooves 8 and a driving device 6. The shell 1 has an opening at the top, and the end cover 2 is adapted to the opening. The locking block 7 is horizontally slidably installed on the top of the end cover 2, the locking groove 8 is arranged on the shell 1 and adapted to the locking block 7, and the driving device 6 is installed on the top of the end cover 2 and connected to the locking block 7.

[0026] It is understandable that when installing the end cover 2, the end cover 2 and the opening are aligned and abutted against each other, and then the driving device 6 can drive the multiple locking blocks 7 to move synchronously, so that the locking blocks 7 are inserted into the locking grooves 8, and the installation of the end cover 2 can be completed. Similarly, when disassembling the end cover 2, the driving device 6 can drive the multiple locking blocks 7 to move and reset synchronously, and then separate the locking blocks 7 from the locking grooves 8, and the disassembly of the end cover 2 can be completed. It can be seen that the installation of the end cover 2 does not require screws to cooperate, that is, it can be done by the cooperation of the locking blocks 7 and the locking grooves 8, which greatly improves the efficiency of disassembly and assembly, and also increases the service life.

[0027] One of the embodiments of the present application is as follows: Figure 2 and Figure 3 As shown, the driving device 6 includes a rotating rod 601 and a pair of sleeves 602. The rotating rod 601 is rotatably installed on the top of the end cover 2, and the sleeve 602 is installed on the top of the locking block 7. The sleeve 602 is sleeved on both ends of the rotating rod 601 and connected to the rotating rod 601 through the guide structure 13.

[0028] It is understandable that when the rotating rod 601 is used, the rotating rod 601 acts on the sleeve 602 through the guide structure 13, and the sleeve 602 can drive the locking block 7 to move synchronously, so that the locking block 7 can move along the axial direction of the rotating rod 601. For example, if the rotating rod 601 rotates forward, the locking block 7 can be moved and inserted into the locking groove 8, thereby completing the installation of the end cover 2; when the rotating rod 601 rotates reversely, the locking block 7 can be moved away from the locking groove 8, thereby completing the removal of the end cover 2.

[0029] like Figure 6 As shown, the present application does not limit the specific structure of the guide structure 13. Only one specific structure is provided below for reference: the guide structure 13 includes a guide groove 1302 and a guide block 1301. The guide block 1301 is installed on the outside of the rotating rod 601, and the guide groove 1302 is arranged in the sleeve 602. The guide groove 1302 has a spiral structure and forms a sliding fit with the guide block 1301.

[0030] It is understandable that when the rotating rod 601 rotates, the guide block 1301 will slide in the spiral guide groove 1302, so that the locking block 7 can move along the axial direction of the rotating rod 601. When the rotating rod 601 rotates to make the locking block 7 and the locking groove 8 cooperate, since the rotating rod 601 is in a free state, that is, there is no limit effect, and the inductor box is installed in the inverter, and the inverter may vibrate during operation, the rotating rod 601 may be reversed, making the cooperation between the locking block 7 and the locking groove 8 unstable.

[0031] In order to solve the above technical problems, one of the embodiments of the present application is as follows: Figure 5 As shown, a torsion spring 11 may be sleeved on the outside of the rotating rod 601 , and two ends of the torsion spring 11 are respectively connected to the end cover 2 and the rotating rod 601 .

[0032] It is understandable that when the locking block 7 is matched with the locking slot 8, the rotating rod 601 can be limited under the elastic force of the torsion spring 11. In this way, the rotating rod 601 can be kept in a limited state, thereby greatly improving the matching stability of the locking block 7 and the locking slot 8.

[0033] Further, such as Figure 4As shown, the rotating rods 601 are preferably provided in two groups (a pair), and the rotating rods 601 are located on both sides of the top of the end cover 2 and are symmetrically distributed, and the corresponding locking blocks 7 and locking grooves 8 also have four groups and are located at the four corners of the end cover 2. In this way, the end cover 2 adopts a four-corner limit installation to improve stability and reliability.

[0034] One of the embodiments of the present application is as follows: Figure 2 , Figure 3 and Figure 4 As shown, in order to improve the high protection performance of the inductor box, that is, to prevent external dust and water vapor from entering the housing 1, a sealing ring 9 can be provided between the opening and the end cover 2; Figure 3 As shown, an inclined surface 10 may be provided on the top inner wall of the locking groove 8 near the outer side.

[0035] It can be understood that when installing the end cover 2, that is, when the locking block 7 enters the locking groove 8, the sealing ring 9 will play a "pad" role, so the locking block 7 may be slightly higher than the locking groove 8, and then when the locking block 7 just enters the locking groove 8, the locking block 7 will first cooperate with the inclined surface 10, and when the locking block 7 continues to move into the locking groove 8, the locking block 7 will perform wedge-shaped extrusion cooperation with the locking groove 8 through the inclined surface 10, thereby driving the end cover 2 to move downward and squeeze the sealing ring 9 to elastically deform, so that the elastically deformed sealing ring 9 can fill the gap between the opening and the end cover 2, thereby greatly improving the sealing and protection performance of the inductor box.

[0036] In this embodiment, Figure 1 and Figure 4 As shown, multiple heat sinks 4 are provided on both sides of the outer wall of the housing 1 to improve the heat dissipation effect of the inductor box. Of course, this is also a common way of heat dissipation. The inductor box is generally installed in the inverter, and there will be a heat dissipation fan in the inverter, such as Figure 1 As shown, if the wind flows along the left and right direction of the inductor box, and the heat sinks 4 are arranged in a straight line, the two adjacent heat sinks 4 will block the heat dissipation wind, thereby making the heat dissipation effect not very good.

[0037] Therefore, in order to solve the above technical problems, a plurality of heat dissipation holes 5 can be provided on the outside of the heat sink 4, so that when the wind flows along the left and right directions of the inductor box, when the wind blows toward the outer surface of the heat sink 4, it will pass through the heat dissipation holes 5 and enter the next heat sink 4, thereby improving the flow effect of the air, thereby greatly improving the heat dissipation effect of the inductor box.

[0038] like Figure 1As shown, in order to further improve the heat dissipation effect of the inductor box, a plurality of mounting posts 3 can be provided at the bottom end of the housing 1; when installing the inductor box, the inductor box can be installed on the mounting surface of the inverter through the mounting posts 3 and bolts, and the mounting posts 3 can maintain a certain heat dissipation gap between the housing 1 and the mounting surface, which can increase the air circulation range in the inductor box, thereby improving the heat dissipation effect; at the same time, it can also reduce the heat transfer from the inductor box to the inverter housing, reducing the impact on the overall temperature of the inverter. Therefore, a reasonable design of the heat dissipation structure of the inductor box is crucial to the stability and reliability of the entire inverter system.

[0039] The working principle of this utility model:

[0040] like Figure 1 As shown, assuming that the end cover 2 is initially installed at the opening of the housing 1, both sides of the top of the end cover 2 have rotating rods 601, and a shift block 12 is installed in the middle of the rotating rod 601 to facilitate the rotation of the rotating rod 601.

[0041] When it is necessary to inspect or replace the inductor in the inductor box, first put your hands on the two side edges of the end cover 2, with four fingers resting on the outside of the shell 1, and then use your thumb to press the dial block 12 to rotate it upward, so that the two rotating rods 601 rotate relative to each other, and the guide block 1301 on the rotating rod 601 will slide in the spiral guide groove 1302, and then act on the sleeve 602 to drive the locking block 7 to move away from the locking groove 8, until the locking block 7 and the locking groove 8 are separated, so that the end cover 2 can be unlocked; of course, when installing the end cover 2, the same principle can be applied in reverse, so that the rotating rod 601 is reversed to drive the locking block 7 to move and insert it into the locking groove 8, which is simple and convenient.

[0042] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
