Description

Technical Field

[0001] This application relates to the field of power converter technology, and in particular to a housing structure and a power converter. Background Technology

[0002] Currently, in the enclosure structure of power converters, the enclosure and top cover are mostly connected by screws. Using screws requires multiple mounting holes to be pre-drilled on the outside of the top cover. Since these mounting holes are exposed, they are easily damaged, affecting the integrity of the enclosure structure, which in turn affects the safety performance of the power converter, and further impacts its aesthetics.

[0003] Therefore, how to improve the integrity of the box structure has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] This application proposes a cabinet structure and a power converter to improve the integrity of the cabinet structure.

[0005] To achieve the above objectives, this application discloses the following technical solutions:

[0006] In a first aspect, this application provides a box structure, including a box body, a top cover and fasteners, with the top cover covering the opening of the box body;

[0007] A support plate is provided at the edge of the opening of the box;

[0008] A connecting plate is provided on the inner side of the top cover, corresponding to the support plate. The connecting plate is provided with a first hanging part, and the support plate is provided with a second hanging part. After the first hanging part and the second hanging part are in place, the fastener connects the support plate and the connecting plate.

[0009] In some embodiments, the first and second holding parts are detachably connected, including a holding position and a detaching position.

[0010] In some embodiments, the connecting plate is provided with a first connecting hole, the support plate is provided with a second connecting hole at a position corresponding to the first connecting hole, and the fastener is threadedly engaged with the first connecting hole or the second connecting hole.

[0011] The first and second holding parts are in the holding position, with the first and second connecting holes aligned; the first and second holding parts are in the disassembly position, with the first and second connecting holes staggered.

[0012] In some embodiments, the first and second hanging parts arranged in pairs are located on both sides of the first and second connecting holes arranged in pairs.

[0013] In some embodiments, the first and second holding portions located on both sides of the first and second connecting holes are arranged symmetrically.

[0014] In some embodiments, the first holding part is a rectangular hole;

[0015] The second holding part includes a root and a hook. The root connects the hook to the support plate, and the hook extends from the root in a direction parallel to the surface of the support plate.

[0016] In some embodiments, the second holding part includes a guide part located at the end of the hook and arranged at an angle.

[0017] In some embodiments, the first hanging part is a gourd hole, including a first hole and a second hole that are interconnected, and the diameter of the first hole is smaller than the diameter of the second hole;

[0018] The second holding part includes a connecting part and a blocking part. The connecting part connects the blocking part and the support plate. The outer diameter of the connecting part is less than or equal to the minimum diameter of the gourd hole. The outer diameter of the blocking part is greater than the diameter of the first hole of the gourd hole and less than the diameter of the second hole of the gourd hole.

[0019] In some embodiments, the connecting plate includes a flap extending from the side wall of the top cover to the center of the top cover, with an installation space between the flap and the top wall of the top cover for accommodating a support plate.

[0020] The support plate includes a side plate extending from the opening of the box body toward the center of the box body.

[0021] Secondly, this application provides a power converter including a housing structure as described in any of the above.

[0022] As can be seen from the above technical solution, in the housing structure of this application, when the top cover needs to be assembled with the housing, the top cover covers the housing. Moving the top cover allows the second holding part to be engaged with the first holding part, and then the fasteners connect the support plate and the connecting plate. Since the connecting plate is located inside the top cover, it is not easily damaged, thus ensuring the integrity of the housing structure. Furthermore, the connection structure between the top cover and the housing is not easily visible from the outside of the housing structure, thus not affecting its aesthetics. In addition, since the top cover and housing use a combination of the first and second holding parts, the number of fasteners used can be reduced, simplifying the installation and disassembly of the top cover.

[0058] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. The described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort are within the scope of protection of the present application.

[0059] In order to improve the integrity of the box structure, this application describes the structure of the box structure in detail with reference to the accompanying drawings:

[0060] See Figures 1 to 22 To achieve the above objectives, this application discloses the following technical solutions:

[0061] A box structure 10 includes a box body 100, a top cover 200, and fasteners 300. The top cover 200 covers the opening of the box body 100. A support plate 110 is provided at the edge of the opening of the box body 100. A connecting plate 210 is provided on the inner side of the top cover 200 at a position corresponding to the support plate 110. A first hanging part 600 is provided on the connecting plate 210, and a second hanging part 700 is provided on the support plate 110. After the first hanging part 600 and the second hanging part 700 are in place, the fasteners 300 connect the support plate 110 and the connecting plate 210.

[0062] In this application's housing structure 10, when the upper cover 200 needs to be assembled with the housing 100, the upper cover 200 covers the housing 100. Moving the upper cover 200 allows the second holding part 700 to be engaged with the first holding part 600, and then the fastener 300 connects the support plate 110 and the connecting plate 210. Since the connecting plate 210 is located inside the upper cover 200, it is less prone to damage, thus ensuring the integrity of the housing structure 10. Furthermore, the connection structure between the upper cover 200 and the housing 100 is not easily visible from the outside of the housing structure 10, thus not affecting its aesthetics. In addition, since the upper cover 200 and the housing 100 use a combination of the first holding part 600 and the second holding part 700, the number of fasteners 300 can be reduced, simplifying the installation and disassembly of the upper cover 200.

[0063] It should be noted that the aforementioned housing 100 and top cover 200 are either non-detachable or detachable. When the housing 100 and top cover 200 are detachably connected, the first hanging part 600 and the second hanging part 700 are also detachably connected, including a hanging position and a dismounting position. Without the fastener 300, in the hanging position, the first hanging part 600 and the second hanging part 700 are held together to achieve initial fixation of the support plate 110 and the connecting plate 210. At this time, the fastener 300 can connect the support plate 110 and the connecting plate 210. In the dismounting position, the top cover 200 can be removed from the opening of the housing 100, and at this time, the fastener 300 cannot connect the support plate 110 and the connecting plate 210.

[0064] To enable the fastener 300 to be connected, the connecting plate 210 is provided with a first connecting hole 400, and the support plate 110 is provided with a second connecting hole 500 at a position corresponding to the first connecting hole 400. The fastener 300 is threaded into the first connecting hole 400 or the second connecting hole 500. The first holding part 600 and the second holding part 700 are located in the holding position, and the first connecting hole 400 and the second connecting hole 500 are aligned. The first holding part 600 and the second holding part 700 are located in the disassembly position, and the first connecting hole 400 and the second connecting hole 500 are staggered.

[0065] In the housing structure 10 of this application, when it is necessary to assemble the upper cover 200 with the housing 100, the upper cover 200 is placed on the housing 100, and the upper cover 200 is moved so that the second hanging part 700 moves to the hanging position in the first hanging part 600, the first connecting hole 400 and the second connecting hole 500 are aligned, and the fastener 300 is aligned with the first connecting hole 400 and the second connecting hole 500, thereby realizing the installation of the upper cover 200 and the housing 100; when it is necessary to remove the upper cover 200 from the housing 100, the fastener 300 is removed from the first connecting hole 400 and the second connecting hole 500, and the upper cover 200 is moved in the opposite direction so that the second hanging part 700 is located in the removal position of the first hanging part 600, thereby realizing the complete separation of the upper cover 200 from the housing 100 and completing the removal of the upper cover 200.

[0066] A first holding part 600 and a second holding part 700 are paired to form a snap-fit ​​point, and a first connecting hole 400 and a second connecting hole 500 are paired to form a fastening point. The snap-fit ​​point can switch between the snap-fit ​​position and the dismount position by moving in a preset direction, and the fastening point is achieved by rotating the fastener 300 to lock and unlock the fastening point.

[0067] To improve the stability of the connection between the top cover 200 and the housing 100, a pair of first hanging parts 600 and second hanging parts 700 are located on both sides of a pair of first connecting holes 400 and second connecting holes 500. Furthermore, the symmetrical arrangement of the first hanging parts 600 and second hanging parts 700 on both sides of the first connecting holes 400 and 500 reduces the occurrence of jamming. The first hanging part 600 can be a regularly shaped oblong hole, a rectangular hole, etc. When the first hanging part 600 is a rectangular hole, it facilitates the movement of the second hanging part 700 in the moving direction, reducing the occurrence of jamming and thus improving the reliability of the top cover 200 during installation and removal.

[0068] See Figures 7 to 12 ,in, Figure 7 A schematic diagram is shown of the top cover 200 installed on the housing 100 (the first hanging part 600 and the second hanging part 700 are in the hanging position). Figure 10 A schematic diagram is shown when the top cover 200 is removed from the housing 100 (the first hanging part 600 and the second hanging part 700 are in the detached position).

[0069] See Figure 8 and Figure 9 , Figure 11 and Figure 12 In some examples, the second holding part 700 includes a root 710a and a hook 720a. The root 710a connects the hook 720a to the support plate 110, and the hook 720a extends from the root 710a in a direction parallel to the surface of the support plate 110. When the second holding part 700 and the first holding part 600 are in the holding position, the root 710a is in contact with the upper edge of the hanging hole or there is a gap. The connecting plate 210 is located between the hook 720a and the support plate 110. Figure 8 and Figure 9 As shown, the top cover 200 can be moved upwards to switch to the detached position (or the housing 100 can be moved downwards to switch to the detached position). When the second hooking part 700 and the first hooking part 600 are in the detached position, the root 710a is in contact with the lower edge of the hook hole or there is a gap, so that the second hooking part 700 can be completely detached from the first hooking part 600, as shown. Figure 11 and Figure 12 As shown, the top cover 200 can be moved downwards to switch to the hanging position (or the box 100 can be moved upwards to switch to the disassembly position).

[0070] To facilitate the installation of the second hanging part 700 into the first hanging part 600, the second hanging part 700 may further include a guide part 730a, which is located at the end of the hook part 720a and is arranged at an angle. Because the guide part 730a is arranged at an angle, during the installation of the top cover 200 into the housing 100, the guide part 730a first contacts the upper edge of the first hanging part 600. The structure of the guide part 730a allows the first hanging part 600 to be stably hung on the second hanging part 700.

[0071] For ease of installation, the second hanging part 700 includes a guide part 730a, which is located at the end of the hook and is arranged at an angle. Because the guide part 730a is arranged at an angle, during the installation of the top cover 200 onto the housing 100, the guide part 730a first contacts the upper edge of the first hanging part 600. The structure of the guide part 730a allows the first hanging part 600 to be stably hung on the second hanging part 700.

[0072] In some examples of this application, the second holding part 700 and the first holding part 600 may also have other structures, see reference. Figures 13 to 22 , Figures 13 to 15 In the box structure 10 shown, the structures of the connecting plate 210 and the support plate 110 can be referred to the above description. In this example, they are similar to... Figures 1 to 12 The most significant difference between the shown box structure 10 and the first and second hanging parts 600 is that their structures differ. For details, see [link to relevant documentation]. Figures 13 to 22 The first hanging part 600 is a gourd hole, which includes a first hole and a second hole that are interconnected, and the diameter of the first hole is smaller than the diameter of the second hole; the second hanging part 700 includes a connecting part 710b and a blocking part 720b. The connecting part 710b connects the blocking part 720b and the support plate 110. The outer diameter of the connecting part 710b is less than or equal to the minimum diameter of the gourd hole. The outer diameter of the blocking part 720b is greater than the diameter of the first hole of the gourd hole and smaller than the diameter of the second hole of the gourd hole.

[0073] When the second holding part 700 and the first holding part 600 are in the holding position, the connecting part 710b is located at the small hole, and the connecting plate 210 is located between the blocking part 720b and the support plate 110. Figure 18 and Figure 19 As shown, the top cover 200 can be moved upwards to switch to the detachable position (or the housing 100 can be moved downwards to switch to the detachable position). When the second hooking part 700 and the first hooking part 600 are in the detachable position, the connecting part 710b is located at the small hole, so that the second hooking part 700 can be completely detached from the first hooking part 600, as shown. Figure 21 and Figure 22 As shown, the top cover 200 can be moved downwards to switch to the hanging position (or the box 100 can be moved upwards to switch to the disassembly position).

[0074] The inner side of the cover 200 can be understood as the side opposite to the box 100, and the side opposite to the inner side, which is the outer side. For ease of understanding of the technical solution of this application, the following definitions are made: the box structure 10 has a length direction, a width direction, and a height direction, where the length direction corresponds to the X-direction in the Cartesian coordinate system shown in the figure, the width direction corresponds to the Y-direction, and the height direction corresponds to the Z-direction. The length, width, and height directions of the cover 200 correspond to the length, width, and height directions of the box structure 10, respectively; the length, width, and height directions of the box 100 correspond to the length, width, and height directions of the box structure 10, respectively.

[0075] To facilitate understanding of the technical solution of this application, the general structure of the housing 100 and the top cover 200 is described below. The housing 100 includes a bottom wall 100a and four side walls 100b connected to each other, with openings formed in the portions of the four side walls away from the bottom wall 100a. The top cover 200 includes a top wall 200a and four side walls 200b connected to each other, with the four side walls 200b forming openings covering the housing 100. The connecting plate 210 includes a flap extending from the side wall of the top cover 200 to the center of the top cover 200, with an installation space between the flap and the top wall of the top cover 200 for accommodating a support plate 110; the support plate 110 includes a side plate extending from the opening of the housing 100 toward the direction away from the center of the housing 100.

[0076] Based on the above description, the movement direction of the second holding part 700 within the first holding part 600 can be either the length direction or the width direction. In this application, the movement of the second holding part 700 within the first holding part 600 along the width direction will be specifically described as an example.

[0077] Combination Figures 1 to 5b In this application example, the connecting plate 210 includes a first flap 211 located at the first edge of the inner side of the cover 200, a second flap 212 located at the second edge, and a third flap 213 located at the third edge. The first flap 211 and the third flap 213 are located on both sides of the second flap 212; the first connecting hole 400 is located on the second flap 212.

[0078] The support plate 110 includes a first edge plate 111 at the first edge of the housing 100, a second edge plate 112 at the second edge, and a third edge plate 113 at the third edge. The first edge plate 111 and the third edge plate 113 are located on both sides of the second edge plate 112. The second connecting hole 500 is located on the second edge plate 112.

[0079] In other words, the first flap 211, the second flap 212, and the third flap 213 are arranged in a U-shape, with the first flap 211 and the third flap 213 used to accommodate the second hanging part 700 or the first hanging part 600; the first edge plate 111, the second edge plate 112, and the third edge plate 113 are also arranged in a U-shape, with the first edge plate 111 and the third edge plate 113 used to accommodate the first hanging part 600 or the second hanging part 700. Therefore, when the top cover 200 is installed in place with the box body 100, the second flap 212 and the second edge plate 112 form a fastening point, and locking points are formed on both sides of the second flap 212 and the second edge plate 112. Specifically, the first flap 211 and the first edge plate 111 form a locking point, and the third flap 213 and the third edge plate 113 form a locking point. There can be one or more locking points on the same side.

[0080] The first holding part 600 is located on the first flap 211 and the third flap 213, such as Figure 4a As shown, the second holding part 700 is located on the first edge plate 111 and the third edge plate 113, as... Figure 4b As shown. In some other examples, the first mounting portion 600 is located on the first edge plate 111 and the third edge plate 113, as shown. Figure 5a As shown, the second holding part 700 is located on the first flap 211 and the third flap 213. Figure 5b As shown. Preferably, this application adopts... Figure 4a and Figure 4b As shown in the structural form, the second hanging part 700 is located in the interlayer between the first flap 211 and the top wall of the upper cover 200, which is not easily touched from the outside and reduces the possibility of scratching people.

[0081] The connecting plate 210 includes a first flap 211, a second flap 212, and a third flap 213 arranged in a U-shape; the supporting plate 110 includes a first edge plate 111, a second edge plate 112, and a third edge plate 113 arranged in a U-shape. In some other examples of this application, the connecting plate 210 is a U-shaped plate, with the first hanging part 600 located on the opposite side of the U-shape and the first connecting hole 400 located at the bottom of the U-shape, such as... Figure 6a As shown, the support plate 110 is a U-shaped plate, the second hanging part 700 is located on the opposite side of the U-shaped structure, and the second connecting hole 500 is located at the bottom of the U-shaped structure, as shown. Figure 6b As shown.

[0082] In addition, in order to improve the connection strength between the top cover 200 and the box 100, the connecting plate 210 includes a fourth flap 214 located at the fourth edge inside the top cover 200, and the fourth flap 214 is provided with a first hanging part 600; the support plate 110 includes a fourth edge plate 114 located at the fourth edge of the box 100, and the fourth edge plate 114 is provided with a second hanging part 700.

[0083] Furthermore, in order to optimize the above technical solution, the first holding part 600 of the fourth flap 214 is open to facilitate the movement of the second holding part 700 located on the fourth edge plate 114.

[0084] The first holding part 600 located on the first flap 211 and the first holding part 600 located on the third flap 213 are arranged symmetrically or asymmetrically, with a symmetrical arrangement. Similarly, the second holding part 700 located on the first edge plate 111 and the second holding part 700 located on the third edge plate 113 are arranged symmetrically. The locking points between the first flap 211 and the first edge plate 111, and between the third flap 213 and the third edge plate 113, are easily synchronized during installation, thereby reducing the occurrence of jamming.

[0085] It should be noted that both the first connecting hole 400 and the second connecting hole 500 can be threaded to the fastener 300, or at least the connecting hole located on the inner side can be threaded to the fastener 300. For example, in the height direction, when the connecting plate 210 is above the support plate 110, the first connecting hole 500 is located on the inner side and the second connecting hole 500 is located on the outer side; in the height direction, when the connecting plate 210 is below the support plate 110, the first connecting hole 500 is located on the outer side and the second connecting hole 500 is located on the inner side.
