[0034] 200 cabinets. Detailed Implementation

[0035] To enable those skilled in the art to better understand the technical solutions of this application, the embodiments of this application will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0036] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of the box in one embodiment of this application.

[0037] This embodiment provides a housing, which includes a mesh door 100. Specifically, at least one side of the housing is provided with a mesh door 100. Figure 1 The enclosure includes a cabinet 200, one side of which is open. A mesh door 100 is installed on the open side of the cabinet 200. The mesh door 100 may include a hinge structure 60, which is rotatably connected to the cabinet 200, allowing for easy opening and closing of the mesh door 100 for assembly, inspection, and maintenance of the internal structure. Depending on actual usage requirements, the enclosure may have mesh doors 100 on two or more sides; this embodiment does not impose specific limitations. The mesh door 100 and the cabinet 200 may be rotatably connected on one side, and locked on the other side via a locking structure. The locking structure is unlocked when the mesh door 100 needs to be opened. Alternatively, the other side may be fixed with bolts or other fasteners. The mesh door 100 and the cabinet 200 may also be fixed with bolts or other fasteners, without requiring a rotatable connection, for example... Figure 1 The central mesh door 100 is rectangular, and at least two of its four sides can be fixedly connected to the cabinet body 200.

[0038] Can be combined Figures 2 to 4 understand, Figure 2 for Figure 1 A structural diagram of the central mesh gate 100, showing the front of the mesh gate 100; Figure 3 for Figure 2 A schematic diagram of the back of the center gate 100; Figure 4 for Figure 3 A magnified view of part A in the middle.

[0039] In this embodiment, the inner cavity of the box is used as a reference. The side of the mesh door 100 closest to the inner cavity of the box is its back, and the side away from the inner cavity is the front of the mesh door 100. When the mesh door 100 is closed, the back of the mesh door 100 is covered by the front.

[0040] In this embodiment, the mesh door 100 includes a door frame 10, which is the main frame structure of the mesh door 100. Figure 1 The enclosure is a cuboid structure, and the door frame 10 also roughly has a rectangular outline. The door frame 10 can also be square or other shapes. The mesh door 100 also includes a wire mesh 20, which comprises multiple wires 201. The wires 201 are, for example, steel wire, which has high strength and is not easily rusted or corroded. Other materials can also be selected for the wires 201 depending on the application requirements. The multiple wires 201 of the wire mesh 20 can be arranged in a crisscross pattern. A first perpendicular direction M and a second perpendicular direction N can be defined. In this case, the wire mesh 20 can include wires 201 extending along the first direction M and wires 201 extending along the second direction N. Figure 1 The height direction of the middle box is also the first direction M. The door frame 10 includes two longitudinal frame beams 1011 extending along the first direction M and two transverse frame beams 1012 extending along the second direction N. The longitudinal wire mesh 201 is parallel to the longitudinal frame beams 1011, and the transverse wire mesh 201 is parallel to the transverse frame beams 1012.

[0041] The mesh door 100 includes a perforated portion 10a defined by the door frame 10. The wire mesh 20 is installed on the door frame 10 and can cover the perforated portion 10a, thus forming a mesh door 100 that can ventilate and dissipate heat. Moreover, the wire mesh 20 can reduce or prevent foreign objects from the external environment from entering the enclosure and play a protective role for the structure inside the enclosure, such as electrical components.

[0042] Can continue to combine Figures 5 to 7 As shown, Figure 5 for Figure 3 A schematic diagram of the structure viewed in cross section along the BB direction; Figure 6 for Figure 5Enlarged schematic diagram of part C in the middle; Figure 7 for Figure 5 A schematic diagram of the structure of the middle connector 30.

[0043] The mesh door 100 in this embodiment also includes a connector 30, which includes at least one slot 301a, with the opening 301a1 of the slot 301a facing the door frame 10. At least one wire 201 of the wire mesh 20 is inserted into one of the slots 301a. Figure 5 One of the connectors 30 includes two slots 301a, in which one wire mesh 201 is inserted, meaning that one connector 30 can simultaneously hold two wire mesh 201. Since the opening 301a1 of the slot 301a faces the door frame 10, the connector 30 and the door frame 10 can jointly enclose the wire mesh 201, limiting its position.

[0044] In some other embodiments, the connector 30 may include a slot 301a, such as Figure 8 As shown, Figure 8 This is a schematic diagram of another type of connector 30, or connector 30 may include more than two slots 301a.

[0045] In some embodiments, two or more wires 201 can be simultaneously inserted into each slot 301a. In this embodiment, the slot 301a of the connector 30 can simultaneously hold two or more wires 201 extending in the same direction, such as simultaneously holding two or more longitudinal or transverse wires 201. However, there is a certain gap between two adjacent wires 201 extending in the same direction. In this embodiment, it is set that one slot 301a holds only one wire 201, which is more conducive to the slot wall of the slot 301a limiting the wire 201 from multiple directions, and the limiting is more reliable.

[0046] In addition, the mesh door 100 also includes fasteners 50. The connector 30 is fixedly connected to the door frame 10 through the fasteners 50, and the fastening method is, for example, threaded connection, riveting, snap-fit, etc. In this embodiment, the fastener 50 is specifically a press-fit screw or a welding screw, which can reliably fix the connector 30 and the door frame 10 together. In this way, the connector 30 can press the mesh wire 201 onto the door frame 10 through the groove wall of the slot 301a, thereby limiting the mesh wire 201 together with the door frame 10, and realizing the connection and fixation of the mesh 20 and the door frame 10. The mesh wire 201 is relatively thin. Compared with the fastener 50 directly connecting the mesh wire 201 and the door frame 10, this embodiment uses the connector 30 to connect to the door frame 10 and then uses the connector 30 to snap the mesh 20, making the fixation of the mesh 20 and the door frame 10 easier to achieve.

[0047] Compared to the prior art method of directly welding the wire mesh 20 to the door frame 10, in this embodiment the wire mesh 20 of the mesh door 100 is detachably connected to the door frame 10 via the connector 30 and fastener 50. The connection is simple and reliable, avoiding problems such as incomplete welding and detachment caused by welding and fixing. The workload is also relatively small. Moreover, if the wire mesh 20 is damaged, it is easy to replace without replacing the entire mesh door 100, thereby reducing the maintenance cost of the mesh door 100.

[0048] Furthermore, if welding is used, rusting is likely to occur at the welding point due to poor coating. However, the wire mesh 20 in this embodiment is, for example, steel wire mesh, which is not prone to rusting under this connection method.

[0049] like Figure 6 As shown, in a specific embodiment, an elastic element 40 can be provided between the groove wall of the slot 301a and the wire mesh 201. The elastic element 40 is made of, for example, rubber or other elastic materials with a certain deformation capacity. During assembly, the elastic element 40 is located between the groove wall of the slot 301a and the outer surface of the wire mesh 201. In this way, the elastic element 40 can be pressed between the connector 30 and the wire mesh 201, realizing an interference fit between the connector 30 and the elastic element 40, and between the elastic element 40 and the wire mesh 201. This reduces or avoids the impact of shaking during transportation on the connection position of the connector 30 and the wire mesh 201, making the connection tighter, improving the reliability of the connection, and also helping to reduce vibration wear.

[0050] In this embodiment, a wire mesh 201 is inserted into each slot 301a of the connector 30. The elastic member 40 can be a ring structure with a through hole 40a. The wire mesh 201 passes through the through hole 40a, and the elastic member 40 is arranged around the wire mesh 201. This can provide more comprehensive support and protection for the wire mesh 201 in the circumferential direction.

[0051] You can continue to refer to this. Figure 9 understand, Figure 9 for Figure 6 A schematic diagram of the structure of the intermediate elastic element 40.

[0052] The elastic element 40 has a break position 40b. In the circumferential direction, the elastic element 40 breaks at the break position 40b. The elastic element 40 includes a first cross-section 401 and a second cross-section 402 located at the break position 40b. The first cross-section 401 and the second cross-section 402 are arranged opposite each other in the circumferential direction of the elastic element 40. The first cross-section 401 and the second cross-section 402 can contact each other or have a gap between them. With this arrangement, the wire mesh 201 can be inserted into the elastic element 40 from the break position 40b. For example, the first cross-section 401 and the second cross-section 402 can extend radially into the elastic element 40, allowing the wire mesh 201 to be inserted radially into the elastic element 40. Therefore, this structure is more conducive to the assembly of the wire mesh 201 and the elastic element 40.

[0053] In some specific embodiments, the connector 30 may include a plate structure, such as Figure 7 As shown, the plate structure includes a plate body 302 and a bent portion 301. The bent portion 301 forms a slot 301a. The bent portion 301 can be a U-shaped structure, thereby forming a slot 301a with the opening 301a1 facing the door frame 10. The plate body 302 can be provided with connecting holes to cooperate with the fastener 50. The plate body 302 can fit snugly against the door frame 10. This type of connector 30 is simple to process, uses less material, and helps to reduce costs. In some other embodiments, the connector 30 can also be of other structural forms, such as a block structure with slots forming the slot 301a.

[0054] Let's look again. Figure 2 In this embodiment, the mesh door 100 may include multiple connectors 30, which are distributed circumferentially along the door frame 10. This allows for the establishment of connections between the wire mesh 20 and the door frame 10 at multiple circumferential positions, thereby reliably fixing the wire mesh 20 and the door frame 10. Specifically, in this embodiment, the wire mesh 20 is connected to the door frame 10 via connectors 30 on both sides along the first direction M and both sides along the second direction N. More specifically, multiple wires 201 around the perimeter of the wire mesh 20 may be equipped with corresponding slots 301a, or only some of the wires 201 may be equipped with slots 301a. Fixing only some of the wires 201 achieves the purpose of reliably fixing the wire mesh 20.

[0055] In some embodiments, the wire mesh 20 may be installed on the back 10-1 of the door frame 10, and the door frame 10 may specifically define at least two openwork portions 10a, such as... Figure 1 and Figure 2As shown, the door frame 10 includes two perforated sections 10a distributed along a first direction M. The door frame 10 also includes a partition beam 1013 located between adjacent perforated sections 10a, which can improve the strength of the door frame 10. A wire mesh 20 can cover the perforated sections 10a. Each perforated section 10a can be covered by a corresponding wire mesh 20, i.e., multiple wire meshes 20 can be provided, or one wire mesh 20 can simultaneously cover multiple perforated sections 20a. Figure 2 Each cutout section 10a is equipped with a corresponding wire mesh 20, which reduces the amount of wire mesh 20 used.

[0056] When the wire mesh 20 is installed on the back 10-1 of the door frame 10, the connectors 30 and fasteners 50 connected to the door frame 10 are not visible from the front view of the mesh door 100, which helps to ensure the cleanliness and aesthetics of the front of the mesh door 100.

[0057] In some embodiments, the mesh gate 100 may further include reinforcing ribs 70, such as Figure 5 As shown, the reinforcing rib 70 is provided on the back 10-1 of the door frame 10, which can improve the structural strength of the mesh door 100 without affecting the neatness and aesthetics of the front of the mesh door 100. In this embodiment, the door frame 10 includes two frame beams (i.e., two longitudinal frame beams 1011) extending along the first direction M and two frame beams (i.e., two transverse frame beams 1012) extending along the second direction N, and at least one frame beam is provided with a reinforcing rib 70 on its back.

[0058] In addition, the door frame 10 in this embodiment may include a frame body 101 and a frame flange 102. The frame body 101 defines the hollow portion 10a. The frame body 101 is a flat plate portion and is parallel to the plane containing the first direction M and the second direction N. The flange 102 extends from the frame body 101 along a third direction S. The third direction S is perpendicular to the first direction M and the second direction N. The direction from the front to the back of the door frame 10 is the third direction S. The reinforcing rib 70 is located on the back 10-1 of the frame body 101. The frame flange 102 can abut against the side wall of the reinforcing rib 70, which limits the reinforcing rib 70. It can also be connected to the reinforcing rib 70, thereby further improving the strength of the door frame 10.

[0059] Please refer to Figure 10 , Figure 10 This is a structural schematic diagram of the mesh door 100 of the box in another embodiment of this application, showing the front of the mesh door 100.

[0060] In this embodiment, the gate 100 and Figure 2 The structure of the mesh gate 100 in the illustrated embodiments is basically the same, except that... Figure 9In this embodiment, the door frame 10 of the mesh door 100 defines a perforated portion 10a, which is used in conjunction with a wire mesh 20. The method of connecting the wire mesh 20 and the door frame 10 through the connector 30 is the same and will not be described again here. It can be seen that the number of perforated portions 10a can be set according to actual needs, and this embodiment does not impose specific limitations.

[0061] The enclosure discussed in the above embodiments can be a cabinet for electrical equipment, such as an inverter, low-voltage cabinet, or PCS (Power Conversion System, energy storage converter), or a transformer, ring main unit, distribution cabinet, etc. Containers or cabinets inside containers can be equipped with the mesh door 100 as described in the above embodiments.

[0062] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of this application.
