Description

Technical Field

[0001] This utility model belongs to the field of electrical control cabinet technology, specifically an electrical control cabinet with expandable functional modules. Background Technology

[0002] In the fields of industrial automation, intelligent manufacturing, power systems, and the control of various large-scale equipment, electrical control cabinets, as core control units, play a crucial role in the installation, wiring, protection, signal transmission, and control of various electrical components. They are an important infrastructure ensuring the stable and efficient operation of the entire system. With the continuous upgrading and iteration of industrial technology, the functional requirements of electrical control systems in various industries are becoming more diversified, personalized, and dynamically changing. For example, during production line transformation, it may be necessary to add functions such as sensor signal acquisition, additional actuator control, and remote monitoring and communication to adapt to higher precision production control requirements or more comprehensive system management needs. However, traditional electrical control cabinets widely used in the market generally have significant limitations in structural design and functional configuration, with the core issue being the lack of expandability of functional modules. Specifically, traditional electrical control cabinets are manufactured with fixed internal electrical component layouts, circuit connections, number and types of interfaces, and control program logic, only meeting the preset functional requirements of specific scenarios. When new control functions need to be added in actual applications, the lack of standardized functional module installation interfaces and expandable architecture within the control cabinet prevents users from directly adding corresponding functional modules to the existing control cabinet. This limitation in functionality, which prevents expansion, has led to a series of significant problems and additional costs for users. First, to meet new functional requirements, users have to replace the entire electrical control cabinet, leaving existing, still-usable cabinets and some electrical components idle or obsolete. This results in a serious waste of equipment resources and significantly increases the procurement costs for equipment upgrades.

[0003] Therefore, an electrical control cabinet with expandable functional modules is proposed to address the above problems. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides an electrical control cabinet with expandable functional modules. This cabinet features expandable internal functions and a pre-existing scalable architecture, allowing for functional expansion based on actual usage needs. This significantly improves the effectiveness of the electrical control cabinet and enriches its functionality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrical control cabinet with expandable functional modules, including an electrical control cabinet body; The surface of the electrical control cabinet body is equipped with expansion function components, which include connecting strips symmetrically arranged inside the electrical control cabinet body, main slide rails formed on the surface of the connecting strips, and disassembly and assembly slots, mounting blocks, main panels, and mounting hole brackets for expansion. The surface of the main panel is equipped with a mounting stabilization assembly, which includes a stabilizing plate mounted on one side of the main panel, a threaded rod threaded into a threaded hole on the surface of the stabilizing plate, and a positioning screw hole for adapting to multiple positions.

[0006] Preferably, a plurality of the disassembly slots are evenly formed on the surface of the connecting strip, and the plurality of the disassembly slots are evenly arrayed along the vertical axis of the connecting strip. The main slide rail and the disassembly slots are an integrated structure. The mounting block is slidably embedded in the interior of the main slide rail and the disassembly slot. The main panel is installed between two mounting blocks. A plurality of mounting hole brackets are symmetrically installed on the surface of the main panel.

[0007] Preferably, the connecting strip is detachably connected to the interior of the electrical control cabinet body by bolts.

[0008] Preferably, the disassembly and assembly slot located on the rear side of the electrical control cabinet body is a one-way slot, and the disassembly and assembly slot located on the front side is a through slot.

[0009] Preferably, the mounting block has multiple balls embedded inside, and the multiple balls are in contact with the main slide rail and the disassembly groove.

[0010] Preferably, a functional interface panel is installed on the inner side wall of the electrical control cabinet body.

[0011] Preferably, a plurality of positioning screw holes are evenly distributed on one side surface of the connecting strip, and one end of the threaded rod passes through the stabilizing plate and is threaded into the interior of the positioning screw holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model incorporates expandable functional components. Through the coordinated use of components such as connecting strips, main slide rails, disassembly and assembly slots, mounting blocks, main panels, and mounting brackets, an expandable architecture is reserved within the electrical control cabinet body. This breaks the limitations of fixed functions in traditional control cabinets, allowing for the flexible addition of functional modules without the need to replace the entire cabinet, thus significantly reducing equipment upgrade costs and resource waste.

[0013] 2. This utility model features a stable installation component with evenly distributed positioning screw holes forming standardized locking positions.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 5 As shown, this utility model provides an electrical control cabinet with expandable functional modules, including an electrical control cabinet body 1; An expansion function component 2 is installed on the surface of the electrical control cabinet body 1. The expansion function component 2 includes connecting strips 21 symmetrically arranged inside the electrical control cabinet body 1, main slide rails 22 opened on the surface of connecting strips 21, and disassembly and assembly slots 23, mounting blocks 24, main panels 25, and mounting hole brackets 26 for expansion. Multiple disassembly slots 23 are evenly formed on the surface of the connecting strip 21, and are evenly distributed along the vertical axis of the connecting strip 21. The main slide rail 22 and the disassembly slots 23 are integrated structures. The mounting block 24 is slidably embedded in the main slide rail 22 and the disassembly slots 23. The main panel 25 is installed between two mounting blocks 24. Multiple mounting brackets 26 are symmetrically installed on the surface of the main panel 25. Through the coordinated use of components such as the connecting strip 21, the main slide rail 22, the disassembly slots 23, the mounting blocks 24, the main panel 25, and the mounting brackets 26, an expandable architecture is reserved in the electrical control cabinet body 1, breaking the limitation of the fixed function of the traditional control cabinet, flexibly adding functional modules, without replacing the entire cabinet, and greatly reducing equipment update costs and resource waste.

[0018] The connecting strip 21 is detachably connected to the interior of the electrical control cabinet body 1 by bolts. If the connecting strip 21 wears out due to long-term use (such as jamming of the main slide rail 22 or deformation of the disassembly groove 23), the user can replace the connecting strip 21 by removing the bolts without replacing the entire control cabinet body, thus reducing maintenance costs. Furthermore, when the user needs to add more functional modules and increase the number of connecting strips 21 or replace them with larger-sized connecting strips 21, the detachable structure allows for flexible adjustment of the number and specifications of the connecting strips 21, thereby enhancing the secondary expansion capability of the control cabinet.

[0019] The disassembly and assembly slot 23 located at the rear of the electrical control cabinet body 1 is a one-way slot, and the disassembly and assembly slot 23 located at the front is a through slot. This allows the mounting block 24 to be pushed in, and the one-way slot at the rear can position the mounting block 24 so that it can smoothly enter the main slide rail 22 for sliding, which greatly improves the use effect of the equipment.

[0020] The mounting block 24 has multiple balls embedded inside, and these balls contact the main slide rail 22 and the disassembly groove 23. The balls convert the sliding friction between the mounting block 24 and the main slide rail 22 and the disassembly groove 23 into rolling friction, which greatly reduces the resistance when pushing the main panel 25. Users can adjust the module position without applying excessive force, thus improving the ease of operation.

[0021] The inner wall of the electrical control cabinet body 1 is equipped with a functional interface panel 27. The functional interface panel 27 integrates standardized power interfaces and data interfaces. New functional modules do not need to be directly connected to the main cables in the cabinet. They only need to be connected to the corresponding interfaces on the panel, which reduces the professional skills required of the operators.

[0022] The surface of the main panel 25 is equipped with a mounting stabilizing component 3. The mounting stabilizing component 3 includes a stabilizing plate 31 mounted on one side surface of the main panel 25, a threaded rod 32 threadedly connected to a threaded hole in the surface of the stabilizing plate 31, and a positioning screw hole 33 for adapting to multiple positions. Multiple positioning screw holes 33 are evenly distributed on one side surface of the connecting strip 21. One end of the threaded rod 32 passes through the stabilizing plate 31 and is threaded into the interior of the positioning screw holes 33. The evenly distributed positioning screw holes 33 form a standardized locking position. No matter what height or front or back position the main panel 25 is adjusted to, the corresponding positioning screw hole 33 can be found and fixed by the threaded rod 32. The threaded locking method can ensure that the main panel 25 and functional modules do not shift, ensuring stable operation of the equipment.

[0023] Among them, the electrical control cabinet body 1 and the functional interface panel 27 are existing technologies, and their working principles are well-known technologies. The appropriate model is selected according to the actual use.

[0024] Working principle and process: Based on the actual functional expansion needs (such as adding PLC control, relay output or remote communication functions), prepare the corresponding functional modules (such as PLC modules, relay modules, etc.). At the same time, check whether the functional interface panel 27 on the inner wall of the cabinet has the corresponding data or power interface to ensure that the interface is undamaged. Fix the functional module to be installed to the mounting hole bracket 26 on the main panel 25 with screws. Multiple mounting hole brackets 26 are symmetrically distributed on the surface of the main panel 25 to ensure that the module does not wobble after installation. Then, align the mounting blocks 24 on both sides of the main panel 25 with the disassembly and assembly slots 23 of the connecting strip 21, and push the main panel 25 along the direction of the disassembly and assembly slots 23 so that the mounting blocks 24 located on the rear side of the cabinet are completely fitted with the disassembly and assembly slots 23 on the rear side, which are set as one-way slots. The structural limitation of the one-way slots is used to achieve precise positioning of the pushing position of the mounting blocks 24 and avoid excessive sliding of the mounting blocks. After the mounting block 24 and the disassembly slot 23 are properly positioned, the mounting block 24 is moved up and down along the vertical axis of the main slide rail 22 according to the actual installation height requirements of the functional module (the main slide rail 22 and the disassembly slot 23 are an integrated structure, and multiple disassembly slots 23 are evenly arrayed along the vertical axis of the connecting strip 21, and the main slide rail 22 provides a stable track for up and down movement). The height position of the main panel 25 is adjusted until the main panel 25 drives the functional module to the ideal installation height. At this time, the mounting block 24 must be in contact with the inner wall of the main slide rail 22 and the corresponding height of the disassembly slot 23 to ensure no lateral offset. After the main panel 25 moves the functional module to the target height and front and back position, the installation stabilization component 3 is activated. The threaded rod 32 on the surface of the stabilization plate 31 is rotated so that one end of it passes through the stabilization plate 31 and is screwed into the corresponding positioning screw hole 33 on one side of the connecting strip 21. Multiple positioning screw holes 33 are evenly distributed. The appropriate screw hole can be selected according to the actual position of the main panel 25. After tightening, it is ensured that the mounting block 24 does not slide in the main slide rail 22 and the main panel 25 does not shake, thus achieving stable fixation of the functional module. Align the mounting blocks 24 on both sides of the main panel 25 directly with the corresponding mounting and disassembly slots 23 on the connecting strip 21. Use multiple mounting and disassembly slots 23 of different heights to achieve pre-installation of the height. There is no need to repeatedly adjust the height. After the mounting blocks 24 are embedded into the mounting and disassembly slots 23 of the target height, the initial height positioning can be completed, which greatly simplifies the operation process. According to the interface type of the functional module (such as power interface and signal interface), connect the module's cable to the corresponding interface on the functional interface panel 27 (e.g., connect the power end of the PLC module to the 24V interface of the functional interface panel 27, and the signal end to the data interface of the functional interface panel 27). After connection, check whether the cable connector is secure to avoid poor contact. Since the disassembly slot 23 has achieved height pre-installation, the module height and interface position match better, which can reduce the problem of cable pulling or insufficient length. After completing the interface connection, power is restored to the electrical control cabinet body 1. Test commands are sent through the external control system or the control unit inside the electrical control cabinet body 1 to verify whether the newly added functional modules are working properly (such as whether the PLC module can receive sensor signals and whether the relay module can perform output actions). If the functional module needs to be adjusted later, first disconnect the power and unscrew the threaded rod 32 to release the fixing of the installation stabilizing component 3; then directly detach the mounting block 24 from the main slide rail 22 and the disassembly slot 23 to disassemble the module.
