[0002] At present, the new energy industry is developing better and better, and the technology of new energy testing is also increasingly needed. The power supply equipment is developing towards modularization. Since the use environment may be dusty, different power modules generally need to be installed with dustproof cotton. The dustproof cotton needs to be replaced regularly after absorbing dust. It is normally fixed with sheet metal screws. The time required for disassembly and assembly of screws and the complexity of the structure are relatively large, which makes it time-consuming and labor-intensive to replace the dustproof cotton. Figure 1 This is an existing power module dust-proof cotton installation structure. When the dust-proof cotton is installed using this structure, the upper baffle 4, the left ear 5 and the right ear 6 are first installed on the panel 1 through the nut 3, and then the dust-proof cotton 2 is placed between the left ear 5 and the right ear 6, and then the sheet metal 7 is installed on the panel 1 through screws. Every time the dust-proof cotton 2 needs to be replaced, the screws for installing the sheet metal 7 need to be removed first, and after the new dust-proof cotton is installed, the sheet metal is fixed to the panel with screws, which makes it time-consuming and labor-intensive to replace the dust-proof cotton.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the technical solution of the utility model is clearly and completely described below in combination with specific embodiments and with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, but not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 2-4 As shown, the present embodiment provides a portable installation structure of dust-proof cotton for a power module, including a panel 10, an upper baffle 20, a lower baffle 30, a left baffle 40, a right baffle 50 and a fixing plate 60. The panel 10 is provided with heat dissipation holes, and the upper baffle 20, the lower baffle 30, the left baffle 40 and the right baffle 50 are all L-shaped. The upper baffle 20 is fixed between the upper edge of the panel 10 and the area where the heat dissipation holes are located, the lower baffle 30 is fixed between the lower edge of the panel 10 and the area where the heat dissipation holes are located, the left baffle 40 is fixed between the left edge of the panel 10 and the area where the heat dissipation holes are located, the right baffle 50 is fixed between the right edge of the panel 10 and the area where the heat dissipation holes are located, and the left baffle 40 and the right baffle 50 are both provided with limiting holes, and both ends of the fixing plate 60 are provided with protrusions, which are engaged in the limiting holes.

[0024] When the installation structure of the utility model is adopted, when the dust-proof cotton 70 is placed in the area where the heat dissipation hole is located, the shape of the dust-proof cotton 70 is adapted to the area enclosed by the upper baffle 20, the lower baffle 30, the left baffle 40, and the right baffle 50. After the fixing plate 60 is fixedly installed through the protrusions and the limiting holes, the fixing plate 60 can fix the dust-proof cotton 70. When the dust-proof cotton needs to be replaced, it is only necessary to pull the fixing plate to disengage the protrusions on the fixing plate from the limiting holes of the left baffle and the right baffle, and then the fixing plate can be removed, and then the dust-proof cotton can be replaced without removing the screws. The operation is simple and convenient, which improves the efficiency of the disassembly and assembly of the dust-proof cotton.

[0025] The lower baffle plate 30 is welded to the panel 10, and the upper baffle plate 20 is mounted on the panel 10 by screws or welding. Figure 4 The method of fixing and installing by screws is illustrated. When installing by screws, two screw holes are provided on the upper baffle plate 20 , and the screws are fixed on the panel 10 after passing through the screw holes.

[0026] The left baffle 40 and the right baffle 50 have the same structure. In this embodiment, the left baffle is used for description. Figure 5 As shown, a first circular hole 41 and a limiting hole 42 are formed on the left baffle plate 40 , and a screw 80 passes through the first circular hole 41 to fix the left baffle plate 40 on the panel 10 .

[0027] like Figure 6 As shown, the dustproof cotton 70 has a first mounting hole 71, a second mounting hole 72, a third mounting hole 73 and a through slot 74, the first mounting hole 71 corresponds to the screw hole on the upper baffle 20, the second mounting hole 72 corresponds to the first round hole 41 on the left baffle 40, the third mounting hole 73 corresponds to the round hole on the right baffle 50, and the folded edge of the lower baffle 30 passes through the through slot 74. By setting the holes and the through slot on the dustproof cotton 70, the installation and positioning of the dustproof cotton can be achieved.

[0028] like Figure 7 As shown, both ends of the fixing plate 60 are provided with a first ear 61 and a second ear 62, and the first ear 61 and the second ear 62 have the same structure and are both L-shaped. The structure of the first ear 61 is introduced for the purpose. The first ear 61 is provided with a first protrusion 612, and a first buckle 611 is provided at its end. Similarly, the second ear 62 is provided with a second protrusion 622, and a second buckle 621 is provided at its end. When the dust-proof cotton is fixedly installed, the first protrusion 612 is engaged in the limiting hole of the left baffle 40, and the second protrusion 622 is engaged in the limiting hole of the right baffle 50. When the dust-proof cotton needs to be removed, the first protrusion 612 can be disengaged from the limiting hole of the left baffle 40 by pulling the first buckle 612 and the second buckle 622, so that the dust-proof cotton can be disassembled for replacement.

[0029] In order to achieve a better assembly effect and to facilitate the removal of the fixing plate from the limiting holes of the left baffle and the right baffle by turning the buckle, the thickness of the first protrusion 612 is generally designed to be one to two times the thickness of the left baffle 40. The thickness of the left baffle 40 is generally 1.2mm-2mm. When the thickness of the left baffle 40 is selected to be 1.2mm, the thickness of the first protrusion 612 is 1.2mm-2.4mm.

[0030] Continue reading Figure 7 The middle of the fixing plate 60 has a window 63 with the same outline as the dustproof cotton, but the size of the window 63 is smaller than the outer size of the dustproof cotton. The upper side, left side and right side of the fixing plate 60 are all provided with holes. The upper side hole corresponds to the screw hole of the upper side baffle 20, the left side hole corresponds to the first round hole 41 of the left side baffle 40, and the right side hole corresponds to the screw installation hole of the right side baffle 50. The lower side of the fixing plate 60 also has a folded edge 64.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
