[0001] This utility model relates to the field of electrical control cabinet technology, and in particular to an electrical control cabinet. Background Technology

[0002] Electrical engineering automation integrates electrical engineering and automation control technologies, encompassing multiple aspects such as power systems, motors and electrical appliances, power electronics, automatic control theory, and computer technology. Electrical engineering automation systems often involve numerous electrical devices and complex control logic. Electrical control cabinets can centrally house various controllers, relays, switches, and other electrical components within a single cabinet, enabling centralized control and management of the entire electrical engineering automation system.

[0003] Currently, existing electrical control cabinets typically bundle multiple cables together to ensure neat wiring. However, when the main control unit inside the electrical control cabinet malfunctions, it is difficult to locate the faulty line and inconvenient for repair. Utility Model Content

[0004] The main purpose of this utility model is to propose an electrical control cabinet that improves the neatness of wire harness placement while facilitating the later identification and repair of faulty lines.

[0005] To achieve the above objectives, the electrical control cabinet proposed in this utility model includes a cabinet body and a wiring harness mounting structure. The cabinet body is provided with a mounting cavity. The wiring harness mounting structure includes a mounting strip, multiple wiring harness fixing members, and multiple telescopic linkage members. The mounting strip is disposed on the cavity wall of the mounting cavity and is provided with a sliding groove. Adjacent wiring harness fixing members are connected through the telescopic linkage members. The wiring harness fixing members are used to fix the wiring harness. One of the multiple wiring harness fixing members is fixed to the mounting strip, and the remaining wiring harness fixing members are slidably disposed in the sliding groove.

[0006] In one embodiment, the wire harness fixing member located at the end of the plurality of wire harness fixing members is fixed to the mounting strip.

[0007] In one embodiment, the wire harness fixing member located at the other end of the plurality of wire harness fixing members is provided with a mounting portion, the mounting portion being detachably connected to the mounting strip.

[0008] In one embodiment, the mounting part is connected to the mounting strip via a threaded rod.

[0009] In one embodiment, the electrical control cabinet further includes a blower device corresponding to the wiring harness mounting structure.

[0010] In one embodiment, the blower includes a blower pipe arranged parallel to the mounting strip, and the blower pipe has blower holes corresponding to at least the wire harness mounting structure.

[0011] In one embodiment, a plurality of air holes are provided, and the plurality of air holes are spaced apart along the length direction of the air pipe.

[0012] In one embodiment, the electrical control cabinet further includes a silencing structure, which is connected to the mounting cavity.

[0013] In one embodiment, the control cabinet further includes a partition that divides the mounting cavity into at least two mounting sub-cavities. The partition has a connecting cavity and a connecting hole that connects the connecting cavity and the mounting sub-cavities. The outside of the cabinet has a vent that communicates with the connecting cavity and the vent has the sound-absorbing structure.

[0014] In one embodiment, the connecting cavity is provided with an air guide plate, which divides the connecting cavity into at least two air guide chambers. Each air guide chamber is connected to one of the mounting sub-cavities, and at least two air guide chambers are connected to the vent.

[0015] In one embodiment, the sound-absorbing structure includes a plurality of first wave peaks and a plurality of second wave peaks, wherein the first wave peaks and the second wave peaks are alternately and staggered in a direction away from the cabinet.

[0016] In one embodiment, the cabinet is provided with ventilation openings; and / or

[0017] The wire harness fixing component includes a fixing ring for the wire harness to pass through.

[0018] The technical solution of this utility model increases the orderliness of the wire harness by setting up wire harness fixing members to fix the wire harness, thus preventing the wire harnesses from tangling. Furthermore, this solution slides the wire harness fixing members on a sliding groove, and adjacent wire harness fixing members are connected by a telescopic linkage. When an operator slides one wire harness fixing member, it moves the telescopic linkage, thereby causing the other wire harness fixing member connected to that telescopic linkage to slide. Similarly, this sequentially causes the other wire harness fixing members to slide, allowing multiple wire harness fixing members to relatively unfold and converge. When multiple wire harness fixing members converge, it facilitates the convergence and restraint of multiple wire harnesses, reducing space occupation. When multiple wire harness fixing members unfold, multiple wire harnesses can be separated, making it easier for maintenance personnel to quickly locate and maintain the wire harnesses. Therefore, this solution improves the neatness of wire harness placement and facilitates later locating and repairing faulty lines. Attached Figure Description

[0035] This utility model proposes an electrical control cabinet.

[0036] Please see Figures 1 to 3 In one embodiment of this utility model, the electrical control cabinet includes a cabinet body 100 and a wiring harness mounting structure 200. The cabinet body 100 is provided with a mounting cavity 110. The wiring harness mounting structure 200 includes a mounting strip 210, a plurality of wiring harness fixing members 220 and a plurality of telescopic linkage members 230. The mounting strip 210 is disposed on the cavity wall of the mounting cavity 110 and is provided with a sliding groove 211. Adjacent wiring harness fixing members 220 are connected by telescopic linkage members 230. The wiring harness fixing members 220 are used to fix the wiring harness. One of the plurality of wiring harness fixing members 220 is fixed to the mounting strip 210, and the remaining wiring harness fixing members 220 are slidably disposed in the sliding groove 211.

[0037] The technical solution of this utility model, by setting up a wire harness fixing member 220 for fixing the wire harness, can increase the orderliness of the wire harness and avoid the wire harnesses from tangling. Moreover, in this solution, the wire harness fixing member 220 for fixing the wire harness is slidably set on the slide groove 211, and two adjacent wire harness fixing members 220 are connected by a telescopic linkage member 230. When the operator slides one wire harness fixing member 220, it will drive the telescopic linkage member 230 to move, thereby driving the other wire harness fixing members 220 connected to the telescopic linkage member 230 to slide. Similarly, it will drive the other wire harness fixing members 220 to slide in sequence, so that multiple wire harness fixing members 220 can be relatively unfolded and converged. When multiple wire harness fixing members 220 converge, it is convenient to bind multiple wire harnesses together and reduce the space occupied. When multiple wire harness fixing members 220 unfold, multiple wire harnesses can be separated, thereby facilitating the quick location of wire harnesses by maintenance personnel for maintenance. It can be seen that this solution can improve the neatness of wire harness placement and facilitate the later location of faulty lines for maintenance.

[0038] Secondly, in this design, the sliding groove 211 is set on the mounting strip 210 and installed on the cavity wall of the mounting cavity 110 via the mounting strip 210. Compared to the design where the sliding groove 211 is directly set on the cavity wall of the mounting cavity 110, the overall wall thickness of the cavity wall of the mounting cavity 110 can be reduced, which helps to reduce the amount of material used in the cabinet 100 and the weight of the cabinet 100. Moreover, during installation, the wire harness fixing component 220 can be installed on the mounting strip 210 first, and then the wire harness installation structure 200 can be modularly installed onto the cavity wall of the mounting cavity 110. This increases the installation operation space of the wire harness fixing component 220, which facilitates the installation operation and improves the installation operation. In addition, during later maintenance, such as when the wire harness fixing component 220 and the groove wall of the sliding groove 211 become stuck, it is also convenient to disassemble the wire harness installation structure 200 as a whole via the mounting strip 210, which facilitates maintenance operations.

[0039] In this design, one of the multiple wire harness fixing components 220 is fixed to the mounting strip 210, while the remaining wire harness fixing components 220 are slidably disposed in the sliding groove 211. This prevents one wire harness fixing component 220 from sliding and causing all the wire harness fixing components 220 to slide in one direction. It is understood that if all the wire harness fixing components 220 slide in one direction, the multiple wire harness fixing components 220 will not fully extend, resulting in a small distance between adjacent wire harness fixing components 220, making quick location difficult. This design fixes one wire harness fixing component 220 to the mounting strip 210. This allows the distance between the first sliding wire harness fixing component 220 and the fixed wire harness fixing component 220 to gradually expand as one wire harness fixing component 220 slides. This facilitates the extension of the telescopic linkage 230 to its maximum extent, thus maximizing the distance between the two wire harness fixing components 220 and facilitating maintenance by operators.

[0040] In this embodiment, the telescopic linkage 230 is configured as a telescopic strip. However, this solution is not limited to this; in other embodiments, the telescopic linkage 230 can also be configured as other linkage components, such as, but not limited to, connecting ropes, nylon strips, etc.

[0041] Reference Figure 3 In one embodiment of this solution, multiple wire harness mounting structures 200 are provided, and the multiple wire harness mounting structures 200 are arranged at intervals along the wiring direction of the wire harness, which facilitates the inspection and maintenance of various parts of the wire harness.

[0042] Reference Figure 2 , Figure 4 and Figure 5 Furthermore, among the multiple wire harness fixing members 220, the wire harness fixing members 220 located at the ends are fixed to the mounting strip 210. This allows the operator to easily slide the wire harness fixing member 220 at the other end, thereby causing all the wire harness fixing members 220 except those fixed to the mounting strip 210 to slide, thus allowing all the wire harness fixing members 220 to unfold or converge, which facilitates maintenance by the operator. Of course, this solution is not limited to this. In other embodiments, among the multiple wire harness fixing members 220, the wire harness fixing member 220 located in the middle may also be fixed to the mounting strip 210, while the wire harness fixing members 220 at both ends are slidably disposed in the slide groove 211.

[0043] In this embodiment, the mounting strip 210 extends vertically along the wall of the mounting cavity 110, and the sliding groove 211 extends along the length of the mounting strip 210. The bottom wire harness fixing member 220 of the plurality of wire harness fixing members 220 is connected to the mounting strip 210. Thus, when the plurality of wire harness fixing members 220 are unfolded, the top wire harness fixing member 220 can be slid, thereby unfolding the plurality of wire harness fixing members 220 to facilitate maintenance. When the plurality of wire harness fixing members 220 are brought together, the top wire harness fixing member 220 can be released, allowing it to slide downwards under gravity, thus bringing the plurality of wire harness fixing members 220 together. Of course, this solution is not limited to this; in other embodiments, the top wire harness fixing member 220 of the plurality of wire harness fixing members 220 can also be fixedly connected to the mounting strip 210.

[0044] Furthermore, one of the multiple wire harness fasteners 220 located at the other end is provided with a mounting portion 221. The mounting portion 221 is detachably connected to the mounting strip 210. It can be understood that by providing the mounting portion 221 on the wire harness fastener 220 located at the other end of the multiple wire harness fasteners 220, and by using the detachable connection between the mounting portion 221 and the mounting strip 210, when the multiple wire harness fasteners 220 are unfolded, the mounting portion 221 can be used to fix the wire harness fastener 220 at the other end to the mounting strip 210. This allows the multiple wire harness fasteners 220 to remain in an unfolded state, thereby freeing the operator's hands and avoiding the situation where the operator's hands must constantly press against the wire harness fasteners 220 at the other end to keep the multiple wire harness fasteners 220 in an unfolded state. Alternatively, when the multiple wire harness fasteners 220 are converged, the mounting portion 221 can also be used to fix the wire harness fastener 220 at the other end, thereby keeping the multiple wire harness fasteners 220 in a converged state.

[0045] Optionally, in this embodiment, the mounting part 221 is connected to the mounting strip 210 via a threaded rod 222. This fastening method is simple and facilitates the operator in fixing the wire harness fixing member 220. Of course, this solution is not limited to this. In the second embodiment, the mounting part 221 can also be snapped into the mounting strip 210. Of course, this solution is not limited to this. In the third embodiment, the wire harness fixing member 220 at the other end can also be locked in the slide groove 211 by damping force. When the operator needs to apply force to the wire harness fixing member 220 at the other end, the wire harness fixing member 220 can slide.

[0046] Specifically, the mounting part 221 is provided with a sliding channel, and the side wall of the slide groove 211 is movably placed in the sliding channel. The side wall of the sliding channel away from the slide groove 211 is provided with a threaded hole, and the threaded rod 222 is threaded on the threaded hole. By rotating the threaded rod 222, the threaded rod 222 is screwed in towards the slide groove 211, thereby pressing the threaded rod 222 against the side wall of the slide groove 211 and fixing it to the mounting strip 210. This connection method makes it convenient for operators to fix the wire harness fixing member 220 at the other end. The wire harness fixing member 220 at the other end can be fixed at any position on the mounting strip 210, avoiding the problem of positioning the mounting part 221. As long as the operator can see the wire harness, the operator can fix the wire harness fixing member 220 at the other end at any time, which can help improve maintenance efficiency.

[0047] Reference Figure 2 , Figure 3 and Figure 9 Optionally, in one embodiment, the electrical control cabinet further includes a blower 300 provided corresponding to the wiring harness mounting structure 200. It is understood that the wiring harness will generate heat after being powered on. This solution provides a blower 300 corresponding to the wiring harness mounting structure 200, which can facilitate the blower 300 to dissipate heat from the wiring harness.

[0048] Furthermore, the blower device 300 includes a blower pipe 310 arranged parallel to the mounting strip 210. The blower pipe 310 has blower holes 320 corresponding to the wire harness mounting structure 200. It can be understood that by setting the blower pipe 310 parallel to the mounting strip 210 and having blower holes 320 corresponding to the wire harness mounting structure 200, the blower pipe 310 can conveniently dissipate heat from the wire harness at various locations, avoiding uneven heat dissipation.

[0049] In this embodiment, the air blower 310 provides air blower holes 320 corresponding to the wire harness mounting structure 200, and also provides air blower holes 320 for the electrical components installed in the mounting cavity 110. This ensures that both the wire harness and the electrical components can receive effective heat dissipation. Of course, this solution is not limited to this. In other embodiments, air blower holes 320 may only be provided corresponding to the wire harness mounting structure 200.

[0050] Furthermore, multiple air vents 320 are provided, spaced apart along the length of the air duct 310. This arrangement ensures uniform air distribution in all directions, preventing excessive or insufficient airflow in certain areas and thus facilitating uniform heat dissipation. Alternatively, the air vents 320 can be elongated, extending along the length of the air duct 310.

[0051] Optionally, the electrical control cabinet also includes a silencing structure 400, which is connected to the mounting cavity 110. It is understood that the electrical control cabinet may generate various noises during operation, such as mechanical vibration and electromagnetic noise. The silencing structure 400 effectively reduces these noises, providing a quieter working environment for operators. Furthermore, continuous noise may adversely affect the electronic components and mechanical equipment inside the electrical control cabinet, such as accelerating aging and reducing accuracy. The silencing structure 400 helps reduce the impact of noise on the equipment, extends its service life, and ensures the stable operation of the electrical control cabinet. Secondly, in some cases, the noise from the electrical control cabinet may mask important alarm signals or fault information, thereby increasing safety hazards. The silencing structure 400 can reduce noise interference to a certain extent, making it easier for operators to detect and identify alarm signals and take timely measures to address potential safety issues.

[0052] Reference Figure 3 , Figure 6 and Figure 7 Optionally, the control cabinet also includes a partition 500, which divides the mounting cavity 110 into at least two mounting sub-cavities 111. The partition 500 has a connecting cavity 510 and a connecting hole 520 connecting the connecting cavity 510 and the mounting sub-cavities 111. A vent communicating with the connecting cavity 510 is provided on the outside of the cabinet 100, and a sound-absorbing structure 400 is provided on the vent. It can be understood that setting the partition 500 to divide the mounting cavity 110 into at least two mounting sub-cavities 111 allows for more rational use of the internal space of the electrical control cabinet. Different electronic components and assemblies can be allocated to different cavities according to their function and size, thereby optimizing the layout and improving space utilization. Furthermore, separating the mounting cavities 110 allows the electronic components in each part to be relatively independent, making it easier to locate specific problem areas during inspection and maintenance without requiring large-scale disassembly of the entire control cabinet. This greatly simplifies the maintenance process and improves work efficiency. The partitioned mounting cavity 110 also allows electronic components to be categorized and managed according to function or type. This not only improves management convenience but also helps reduce malfunctions caused by misoperation or confusion. Furthermore, electronic components inside the electrical control cabinet may generate electromagnetic interference. By using the partitioned mounting cavity 110, susceptible components can be isolated from interference-generating components, thereby improving the electromagnetic compatibility of the entire system.

[0053] It should be noted that the partition 500 has a connecting cavity 510, and the partition 500 has a connecting hole 520 connecting the connecting cavity 510 and the mounting sub-cavity 111. The outer side of the cabinet 100 has a vent that communicates with the connecting cavity 510, and the vent has a sound-absorbing structure 400. It can be understood that the sound-absorbing structure 400 is typically used to reduce noise inside the electrical control cabinet. The connecting cavity 510 can further optimize the noise propagation path, allowing noise to be more effectively absorbed or isolated when passing through the connecting cavity 510, thereby achieving a better noise reduction effect. Various electromagnetic interference sources may exist inside the electrical control cabinet. The introduction of the connecting cavity 510 can also serve as an electromagnetic shielding measure, separating the electromagnetic fields of different areas, reducing mutual interference, and improving the electromagnetic compatibility of the entire system. Furthermore, the design of the connecting cavity 510 can also guide airflow within the control cabinet, making it flow more smoothly. Through communication with the sound-absorbing structure 400, heat generated inside the control cabinet can be more effectively discharged, reducing the operating temperature of the equipment and ensuring the stable operation of electrical components.

[0054] Furthermore, a guide plate 530 is provided inside the connecting cavity 510, which divides the connecting cavity 510 into at least two air guiding cavities 511. One air guiding cavity 511 is connected to a corresponding installation sub-cavity 111. Both air guiding cavities 511 are connected to the vent. The connecting hole 520 corresponding to one air guiding cavity 511 is connected to the installation sub-cavity 111. It can be understood that by setting the guide plate 530 to separate the connecting cavity 510 inside the connecting cavity 510, the airflow in different installation sub-cavities 111 can be discharged to the vent through their respective connected air guiding cavities 511, avoiding the chaos and disorder of airflow, while providing a clear channel for external gas.

[0055] The air blower 310 passes through the partition 500 and the air guide plate 530, so that the electronic components and wiring harnesses in multiple mounting cavities 111 can be cooled by one air blower 300. This ensures that the electrical components and wiring harnesses in multiple mounting cavities 110 can be effectively cooled, avoiding uneven heat dissipation.

[0056] Furthermore, in this embodiment, the partition 500 extends horizontally to divide the mounting cavity 110 into mounting sub-cavities 111 distributed vertically. A noise-absorbing structure 400 is provided on each side of the partition 500 in the left and right directions, thus further improving the noise-absorbing structure 400 of the electrical control cabinet. Of course, this solution is not limited to this. In the second embodiment, the partition 500 can also extend vertically to divide the mounting cavity 110 into mounting sub-cavities 111 distributed horizontally. The noise-absorbing structure 400 is located at the top of the cabinet 100 and communicates with the communicating cavity 510 of the partition 500. Of course, this solution is not limited to this. In the third embodiment, the partition 500 extends in the horizontal direction to divide the mounting cavity 110 into mounting sub-cavities 111 distributed in the vertical direction. A sound-absorbing structure 400 is provided only on the left or right side of the partition 500; or a sound-absorbing structure 400 is provided on the left, right and rear sides of the partition 500, and is connected to the communicating cavity 510 of the partition 500 respectively.

[0057] Reference Figure 8 The sound-absorbing structure 400 includes multiple first wave-shaped plates 410 and multiple second wave-shaped plates 420. The first and second wave-shaped plates 410 and 420 are alternately and staggered along a direction away from the cabinet 100. This forces noise to travel a tortuous path when propagating within the sound-absorbing structure 400. The uneven surface of the wave-shaped plates causes multiple reflections when noise comes into contact with them, gradually dissipating sound energy and thus reducing noise. Furthermore, the material of the wave-shaped plates typically has sound-absorbing properties, further absorbing noise energy. However, this solution is not limited to this; in other embodiments, the sound-absorbing structure 400 may also include multiple layers of sound-absorbing material disposed at the vent.

[0058] Furthermore, the connection port of the sound-absorbing structure 400 to the external environment is equipped with a filter screen to filter impurities contained in the external air and prevent impurities from entering the mounting cavity 110 of the cabinet 100.

[0059] Reference Figures 1 to 3 In one embodiment, the cabinet 100 is provided with a vent 120. It can be understood that the vent 120 can balance the air pressure inside and outside the cabinet 100. During the operation of the electrical control cabinet, various factors may cause changes in the air pressure inside the cabinet 100. The presence of the vent 120 can keep the air pressure inside the cabinet 100 relatively balanced with the external environment, avoiding damage to the structure of the cabinet 100 due to excessive air pressure difference. At the same time, it can discharge the gas inside the cabinet 100 to the outside. Furthermore, a filter screen is detachably installed inside the vent 120, so that the gas entering the mounting cavity 110 can be filtered. The detachable direction is, for example, but not limited to, clips or bolts.

[0060] The filter screen can have one or two layers; there is no specific limit on the number of filter screen layers.

[0061] In this embodiment, the cabinet 100 is provided with a vent 120 for each mounting sub-cavity 111.

[0062] Optionally, the wire harness fixing member 220 includes a fixing ring 223 for the wire harness to pass through. Inserting the wire harness into the fixing ring 223 secures the wire harness, making the installation simple and easy to operate. However, this solution is not limited to this. In other embodiments, the wire harness fixing member 220 may include a fixing buckle to fasten the wire harness to the wire harness fixing member 220.

[0063] It should be noted that the retaining ring 223 has a mounting and disassembly port, which facilitates the installation and removal of the wire harness.

[0064] Furthermore, a protective pad is provided on the inner wall of the retaining ring 223 to prevent the retaining ring 223 from damaging the wire harness. The protective pad is, for example, but not limited to, rubber pads and nylon pads.

[0065] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
