Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.

As shown in fig. 1 to 3, the detachable household inverter according to the present invention includes an upper case 11 with an opening formed at the bottom, a lower case 12 with an opening formed at the top, and a circuit board 2. The upper shell 11 and the lower shell 12 are combined with each other up and down to form the shell structure 1. Specifically, the open edge of the upper housing 11 and the open edge of the lower housing 12 are attached to each other to form the housing structure 1. The housing structure 1 is formed with a mounting cavity inside, and windows 13 are formed on the left and right sides of the housing structure 1. The window 13 communicates with the mounting cavity. Electronic components are arranged on the circuit board 2. The circuit board 2 is horizontally mounted in the mounting cavity by screws and is fixedly connected with the lower housing 12. A cover assembly for covering the window 13 is installed corresponding to each window 13. The cover assembly includes a frame 3 and a cover plate 31. The frame body 3 is formed by connecting a plurality of frame edges end to end. The frame 3 can be movably sleeved outside one end of the shell structure 1. The cover plate 31 is connected to the frame 3 by a connecting member 32. The number of the connecting members 32 arranged between the cover plate 31 and the frame body 3 depends on the actual requirements. By adjusting the position of the frame 3 on the housing structure 1 in the left-right direction, the cover plate 31 can be closed on the window 13, thereby closing the window 13. When the cover plate 31 is covered on the window 13, the frame 3 is fixedly connected to the upper housing 11 and the lower housing 12 by fasteners, respectively. With the above-described configuration, the frame 3 fixes the cover plate 31 covering the window 13, and the combined upper case 11 and lower case 12 can be fixed to each other. A vent 4 (shown in fig. 11) is formed in the cover plate 31 of the cover assembly on one side. The cover plate 31 of the cover assembly on the other side is provided with an air outlet 5. A heat dissipation fan 51 (shown in fig. 10) is installed in the air outlet 5 of the cover plate 31. The heat radiation fan 51 is arranged toward the outlet 5 so as to be able to guide heat inside the case structure 1 out of the outlet 5. And filter screens for isolating dust can be arranged on the air vent 4 and the air outlet 5. The wire of the heat dissipation fan 51 is provided with a male connector, and the male connector is connected with the female connector on the circuit board 2 in an inserting manner, so that the heat dissipation fan 51 provides a working power source through the circuit board 2.

As shown in fig. 4 and 5, notches 7 are formed at the edges of the left and right sides of the opening of the upper case 11 and at the edges of the left and right sides of the opening of the lower case 12. The notches 7 on the corresponding sides form the windows 13 described above when the upper case 11 and the lower case 12 are combined with each other. The size of the gap 7 depends on the actual requirement. In the present embodiment, the notches 7 are formed in an open shape on the left and right sides of the upper case 11 and on the left and right sides of the lower case 12 in order to facilitate the manufacturing process of the upper case 11 and the lower case 11.

As shown in fig. 2-5, a plurality of bayonets 121 are formed at the front and rear edges of the opening of the lower case 12. A plurality of sockets 21 are mounted on the circuit board 2. The socket is clamped in the corresponding bayonet 121. The socket 21 includes a socket connected to ac power and a socket electrically connected to dc power. The upper housing 11 has a protrusion 111 formed at an open edge thereof corresponding to the bayonet 121. When the upper housing 11 and the lower housing 12 are assembled with each other, the lower end of the boss 11 extends into the corresponding bayonet 121 and abuts against the socket 21 located in the opening 121. Through the above structural design, the positioning and fixing of the socket 21 in the bayonet 121 are realized. To achieve better fixation of socket 21, a soft rubber pad is mounted on the bottom of boss 111. When assembling, the soft rubber pad is abutted against the socket 21

As shown in fig. 6-8, the lower housing 12 is formed with a first step structure 122 at the open edge thereof. The upper case 11 is provided at an open edge thereof with a second stepped structure 112 corresponding to the first stepped structure 122. When the first stepped structure 122 and the second stepped structure 112 are combined up and down to form the housing structure 1, the upper housing 11 and the lower housing 12 are fitted to each other more tightly, and relative sliding does not occur.

As shown in fig. 2 and 3, during assembly, the frame 3 and the housing structure 1 may be designed to be tightly coupled, which is beneficial to improving the stability and the aesthetic degree of the overall structure. The frame 3 is connected to the upper case 1 and the lower case 2 in such a manner that through holes 6 are distributed on the frame side of the frame 3. The center axis of the through-hole 6 extends in the left-right direction. The upper shell 11 and the lower shell 12 are provided with threaded holes 61 corresponding to the through holes 6. The fastener is a screw. In assembly, the frame body 3, the upper case 11, and the lower case 12 are fixedly connected together by screws.

During assembly, the circuit board 2 is first mounted in the lower housing 12 by screws, and the socket 21 on the circuit board 2 is simultaneously snapped into the bayonet 121. Then, the upper housing 11 is covered on the lower housing 11, and the protrusions 111 on the upper housing 11 are synchronously inserted into the corresponding bayonets 121, so that the upper housing 11 and the lower housing 12 are combined into the housing structure 1. The plug connector on the lead of the cooling fan 51 is plugged into the circuit board 2 from the window 13 on one side, then the cover plate components on the left side and the right side are respectively sleeved outside the two ends of the shell structure 1 through the frame bodies 3, the positions of the frame bodies 3 on the two sides are respectively adjusted left and right, so that the cover plate 31 can be covered on the window 13 on the corresponding side, and finally the frame bodies 3, the upper shell 11 and the lower shell 12 are fixedly connected together through screws. The upper shell 11 and the lower shell 12 are not fixed by screws, so that the assembly steps of the inverter are simplified, and the assembly efficiency of the inverter is improved

When dust is cleaned, the cover plate assemblies on both sides are detached separately, and the heat dissipation fan 51 and the ventilation opening 4 can be detached. The detached cover plate assembly with the vent 4 can flush the vent 4 and the filter screen on the vent 4 by water flow to clean off the attached dust. The detached cover plate assembly having the heat radiating fan 51 may be blown by a blower to clean the attached dust. When the heat dissipation fan 51 has waterproof performance, the water flow can be used to wash the heat dissipation fan to clean the attached dust. Through the above operation manner, the blades of the cooling fan 51 and the dust on the ventilation opening 4 are easily cleaned, thereby improving the service life of the inverter.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
