Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically a multi-functional modular distribution box. Background Technology

[0002] As a core device in power systems used for distributing electrical energy and protecting circuit equipment, distribution boxes are widely used in various fields such as industrial production, civil buildings, and municipal facilities. With the increasing integration of power equipment and the diversification of usage scenarios, the operational stability, heat dissipation efficiency, and protection performance of distribution boxes have gradually become key factors affecting their service life and safety performance. However, existing distribution boxes still have many problems that urgently need to be solved in practical applications.

[0003] In terms of heat dissipation performance, traditional distribution boxes mostly adopt passive heat dissipation methods with ventilation holes on the side walls of the box, or active heat dissipation through fixed cooling fans. However, passive heat dissipation is greatly affected by ambient temperature. In high-temperature environments or when equipment is operating under high load, heat is easily accumulated inside the box, causing electrical components to malfunction due to overheating. While fixed cooling fans can improve heat dissipation efficiency, they also present the problem of inconvenience in disassembly and maintenance. If the cooling fan needs to be repaired or replaced, it is often necessary to disassemble part of the box structure, which is cumbersome and time-consuming. At the same time, external dust and impurities can easily enter the box through the ventilation holes or cooling fans, and long-term accumulation will adhere to the surface of electrical components, not only affecting the heat dissipation effect, but also potentially causing safety hazards such as short circuits.

[0004] In terms of protective performance, existing distribution boxes are mostly designed for the overall enclosure, such as using waterproof shells and reinforcing the wall thickness, but they do not pay enough attention to the specific protection of vulnerable parts such as heat dissipation vents. As a key channel for air circulation between the enclosure and the outside, the heat dissipation vents have relatively low structural strength. In outdoor use or industrial environments, they are prone to deformation and damage if subjected to external forces such as collisions or impacts, allowing rainwater and foreign objects to enter the enclosure. Although some distribution boxes have simple protective nets or baffles at the heat dissipation vents, they only provide basic shielding and cannot effectively buffer impact forces. Moreover, the protective structure is often integrally formed with the enclosure or bolted on, making subsequent maintenance and replacement difficult and unable to meet the long-term protection needs of complex environments.

[0005] In addition, the functional modules of existing distribution boxes (such as heat dissipation and protection components) are mostly integrated designs, and there is a lack of space for independent assembly and flexible adjustment between modules. When a module fails, the entire structure often needs to be repaired, which not only increases maintenance costs but also reduces the overall efficiency of the distribution box.

[0006] Therefore, it is necessary to study a multifunctional modular distribution box. Utility Model Content

[0007] To address the problems mentioned in the background art, the purpose of this utility model is to provide a multifunctional modular distribution box that has the advantages of efficient heat dissipation and easy maintenance, reliable dedicated protection for heat dissipation vents, and flexible assembly of functional modules. It solves the problems of low passive heat dissipation efficiency or cumbersome disassembly and assembly of active heat dissipation modules in traditional distribution boxes, lack of effective protection for weak heat dissipation vents that are easily damaged, and high maintenance costs and poor flexibility caused by the integrated design of functional modules.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional modular distribution box, including a distribution box body, a heat dissipation module and a protection module. The distribution box body has symmetrical heat dissipation vents on both sides. A snap-fit ​​frame is fixedly connected to the outside of the heat dissipation vents. The top of the snap-fit ​​frame has an installation groove, and the bottom of the installation groove is threadedly connected to the heat dissipation module by bolts. The heat dissipation module includes a mounting frame installed inside the snap-fit ​​frame. A heat dissipation fan is installed inside the mounting frame and is connected to a heat dissipation vent. A filter groove is provided on the top of the mounting frame. A filter screen is snapped into the filter groove and is located outside the heat dissipation fan. The protective module includes four mounting bases, which are installed in pairs on both sides of the heat dissipation vent. Each mounting base has a snap-fit ​​strip symmetrically fixedly connected to its surface. Two of the snap-fit ​​strips have hollow strips snapped into their interiors. Each hollow strip has a compression opening on its outer side. A buffer air cushion is fixedly connected inside the compression opening. The other end of the buffer air cushion is fixedly connected to a compression strip, which is slidably connected to the compression opening. A protective strip is fixedly connected to the outer side of the compression strip.

[0009] As a preferred embodiment of this utility model, the filter tank is provided with symmetrical positioning ports on both sides, the filter screen is provided with symmetrical positioning grooves on the surface, an ejector spring is fixedly connected inside the positioning groove, a positioning post is fixedly connected outside the ejector spring, and the positioning post is slidably connected to the positioning groove and engaged with the positioning port.

[0010] As a preferred embodiment of this utility model, a triangular reinforcing block is fixedly connected to the bottom of the snap-fit ​​strip, and a sealing cap is snapped onto the top of the snap-fit ​​strip, and the sealing cap is used in conjunction with the hollow strip.

[0011] As a preferred embodiment of this invention, an arc-shaped elastic strip is fixedly connected to the outer side of the protective strip, and the height of the elastic strip is greater than the height of the mounting base.

[0012] As a preferred embodiment of this utility model, a sunshade module is installed on the top of the distribution box. The sunshade module includes two symmetrical mounting parts, and a sliding strip is slidably connected to the surface of the mounting parts. The top of the two sliding strips is fixedly connected to the same sunshade plate.

[0013] As a preferred embodiment of this utility model, a through post is symmetrically arranged on one side of the mounting component, and a locking cap is threadedly connected to the other end of the through post through a sliding strip. Both ends of the mounting component are snapped with closed caps.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model sets a snap-fit ​​frame on the outside of the heat dissipation vents on both sides of the distribution box body, and uses the bolts in the mounting groove at the top of the snap-fit ​​frame to connect with the mounting frame of the heat dissipation module. With the connection design between the heat dissipation fan and the heat dissipation vent inside the mounting frame, it not only realizes the detachable assembly of the heat dissipation module and the box body, which is convenient for later maintenance and replacement, but also accelerates the exhaust of hot air inside the box through the heat dissipation fan. At the same time, the filter plate snapped in the filter groove at the top of the mounting frame can filter dust and impurities in the incoming air. Compared with the existing fixed heat dissipation structure, it takes into account efficient heat dissipation, impurity protection and maintenance convenience, and solves the problems of cumbersome disassembly and assembly of heat dissipation components in traditional distribution boxes and easy dust accumulation affecting heat dissipation efficiency.

[0015] 2. This utility model provides a protective module consisting of a mounting base, a snap-fit ​​strip, a hollow strip, a buffer air cushion, a compression strip, a protective strip, and an elastic strip on both sides of the heat dissipation vent. The elastic strip utilizes its arc-shaped structure and elastic deformation to initially buffer the impact force, while the buffer air cushion absorbs energy through deformation, forming a double protection. At the same time, the triangular reinforcing block at the bottom of the snap-fit ​​strip enhances the structural strength, and the top sealing cover provides a sealed protection. Compared with the existing single protective structure, this not only improves the impact protection effect on the heat dissipation vent and the enclosure, but also prevents rainwater and dust from entering, extends the service life of components, and solves the problem of the traditional distribution box protective structure having a single function and limited protective effect.

[0018] 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.

[0019] like Figures 1 to 4 As shown, the present invention provides a multifunctional modular distribution box, including a distribution box body 1. The distribution box body 1 has symmetrical heat dissipation vents 11 on both sides for air circulation inside and outside the box, providing a channel for heat dissipation. A snap-fit ​​frame 12 is fixedly connected to the outside of the heat dissipation vent 11. The top of the snap-fit ​​frame 12 has an installation groove 13, and the bottom of the installation groove 13 is threadedly connected to the heat dissipation module 2 by bolts. The heat dissipation module 2 and the snap-fit ​​frame 12 are detachably fixed by bolts, which facilitates the subsequent maintenance or replacement of the heat dissipation module 2. The heat dissipation module 2 includes a mounting frame 21 installed inside the snap-fit ​​frame 12. A heat dissipation fan 22 is installed inside the mounting frame 21 and is connected to the heat dissipation vent 11. Activating the heat dissipation fan 22 can accelerate the exhaust of hot air from the heat dissipation vent 11 inside the box, thereby improving heat dissipation efficiency. A filter groove is provided on the top of the mounting frame 21. A filter screen 23 is snapped into the filter groove and is located outside the heat dissipation fan 22. The filter screen 23 can filter the air entering the heat dissipation fan 22 and prevent dust and impurities from entering the distribution box 1 and affecting the operation of electrical components. The outer side of the distribution box 1 is also equipped with a protective module 3. The protective module 3 includes four mounting bases 31. The four mounting bases 31 are installed in pairs on both sides of the heat dissipation vent 11 to provide the installation base for the protective structure. The mounting base 31 is symmetrically fixedly connected with snap-fit ​​strips 32. Hollow strips 33 are snapped into the inside of two snap-fit ​​strips 32, and the hollow strips 33 are set around the outer periphery of the heat dissipation vent 11 to form a surrounding protection for the heat dissipation vent 11. The outer side of the hollow strips 33 is provided with a compression port. The inside of the compression port is fixedly connected with a buffer air cushion 34. The other end of the buffer air cushion 34 is fixedly connected with a compression strip 35, and the compression strip 35 is slidably connected to the compression port. The outer side of the compression strip 35 is fixedly connected with a protective strip 36. When the outside is impacted, the protective strip 36 drives the compression strip 35 to compress the buffer air cushion 34. The deformation of the buffer air cushion 34 absorbs the impact force and achieves protection for the heat dissipation vent 11.

[0020] refer to Figure 2 and Figure 4 The filter tank has symmetrically arranged positioning ports 24 on both sides, and the filter screen plate 23 has symmetrically arranged positioning grooves on its surface. An ejector spring 25 is fixedly connected inside the positioning groove, and a positioning post 26 is fixedly connected to the outside of the ejector spring 25. The positioning post 26 is slidably connected to the positioning groove and engages with the positioning port 24. When installing the filter screen plate 23, the ejector spring 25 pushes the positioning post 26 into the positioning port 24 to achieve precise positioning of the filter screen plate 23. When disassembling, pressing the positioning post 26 can release the fixation, which is convenient for cleaning or replacing the filter screen plate 23.

[0021] As a technical optimization of this utility model, the cooperative structure of the ejector spring 25 with the positioning column 26 and the positioning port 24 replaces the traditional bolt fixing method, which not only ensures the stability of the filter screen 23 after installation, but also simplifies the disassembly and assembly process. The filter screen 23 can be maintained without the aid of tools, thus improving the convenience of daily maintenance of the equipment.

[0022] refer to Figure 2 and Figure 3 The bottom of the snap-fit ​​strip 32 is fixedly connected to a triangular reinforcing block 37, which can enhance the connection strength between the snap-fit ​​strip 32 and the mounting base 31 and prevent the snap-fit ​​strip 32 from deforming under force. The top of the snap-fit ​​strip 32 is snapped with a sealing cover 38, which works in conjunction with the hollow strip 33 to seal the connection between the snap-fit ​​strip 32 and the hollow strip 33, preventing rainwater and dust from entering and corroding the internal components.

[0023] As a technical optimization of this utility model, the triangular stabilizing structure of the triangular reinforcing block 37 strengthens the load-bearing capacity of the snap-fit ​​strip 32, solving the problem of the snap-fit ​​strip 32 being prone to bending under long-term stress; at the same time, the sealing cover 38 is used to shield and seal, constructing a dual guarantee of "structural reinforcement + sealing protection" for the protective module 3, extending the overall service life of the protective module 3, and is especially suitable for outdoor humid and dusty environments.

[0024] refer to Figure 2 and Figure 3 An arc-shaped elastic strip 39 is fixedly connected to the outer side of the protective strip 36, and the height of the elastic strip 39 is greater than the height of the mounting base 31. The arc structure allows the elastic strip 39 to contact the impacting object before the protective strip 36, and initially buffers the impact force through its own elastic deformation. Together with the buffer air cushion 34, it forms double protection and further improves the protection effect.

[0025] As a technical optimization of this utility model, the graded protection design of "arc elastic strip 39 for initial buffering + buffer air cushion 34 for secondary energy absorption" weakens the external impact force in stages, avoiding the direct action of a single impact force on the heat dissipation port 11 and internal components; at the same time, the height design of the elastic strip 39 protruding from the mounting base 31 ensures that the elastic strip 39 is in contact with the impact first, maximizing the graded protection effect and reducing the risk of damage to the heat dissipation port 11.

[0026] refer to Figure 1 and Figure 2 A sunshade module 4 is installed on the top of the distribution box 1. The sunshade module 4 includes two symmetrical mounting parts 41. Sliding strips 42 are slidably connected to the surface of the mounting parts 41. The top of the two sliding strips 42 is fixedly connected to the same sunshade plate 43. The sunshade plate 43 can block sunlight from shining directly on the top of the distribution box 1, reducing the heat accumulation of the box due to sun exposure. At the same time, the sliding strips 42 can slide along the mounting parts 41, making it easy to adjust the position of the sunshade plate 43 to adapt to different usage scenarios.

[0027] As a technical optimization of this utility model, the physical shading effect of the sunshade 43 reduces the heat absorption of the box from the source, forming a collaborative heat dissipation system of "active heat dissipation + passive temperature control" with the heat dissipation module 2, thereby improving the overall heat dissipation efficiency of the distribution box; while the sliding cooperation between the slide bar 42 and the mounting part 41 allows the sunshade 43 to be flexibly adjusted according to the seasonal sunlight angle and the shading needs of the installation environment, solving the problem of the single applicable scenario of the traditional fixed sunshade structure.

[0028] refer to Figure 1 and Figure 2One side of the mounting component 41 is symmetrically provided with a through post 44, and the other end of the through post 44 passes through the slide bar 42 and is threadedly connected to a locking cap 45. After adjusting the position of the sunshade 43, tightening the locking cap 45 can fix the slide bar 42 and prevent the sunshade 43 from shifting. Both ends of the mounting component 41 are snapped with a closed cap, which can block the opening at the end of the mounting component 41 and prevent impurities from entering and affecting the smooth sliding of the slide bar 42.

[0029] As a technical optimization of this utility model, the threaded locking structure of the through column 44 and the locking cap 45 enables precise fixing of the position of the slide bar 42, ensuring that the sunshade 43 does not shift under wind, vibration and other environments; at the same time, the sealing and protective design of the closed cover prevents sand and rainwater from entering the interior of the mounting part 41 and causing the slide bar 42 to jam, ensuring the long-term stable operation of the sunshade module 4 adjustment function.

[0030] Working principle and usage process of this utility model: When using this multi-functional modular distribution box, the assembly of each module is performed first: First, place the distribution box body 1 in the designated installation position, then assemble the heat dissipation module 2. Align the mounting frame 21 in the heat dissipation module 2 with the snap-fit ​​frame 12 on the outside of the heat dissipation vents 11 on both sides of the distribution box body 1 and place it inside the snap-fit ​​frame 12. Secure the mounting frame 21 to the snap-fit ​​frame 12 with the bolts at the bottom of the mounting groove 13 on the top of the snap-fit ​​frame 12. Next, take out the filter screen 23 and press the positioning groove on the surface of the filter screen 23. The positioning post 26 compresses the ejector spring 25 in the positioning groove, causing the filter screen 23 to be inserted into the filter groove at the top of the mounting frame 21. Releasing the positioning post 26 causes the ejector spring 25 to reset, pushing the positioning post 26 to engage with the positioning ports 24 on both sides of the filter groove, thus completing the installation of the filter screen 23. Next, the protective module 3 is assembled, with the four mounting bases 31 fixed in pairs on both sides of the heat dissipation vents 11 of the distribution box body 1. Hollow strips 33 are inserted into the symmetrically fixed snap-fit ​​strips 32 on the surface of the mounting bases 31. At this point, the triangular reinforcing block 37 at the bottom of the snap-fit ​​strip 32 enhances the connection strength between the snap-fit ​​strip 32 and the mounting base 31. Then, the sealing cap 38 is snapped onto the top of the snap-fit ​​strip 32 to cooperate with the hollow strip 33 to achieve a seal. The other end of the buffer air cushion 34 fixed inside the outer extrusion port of the hollow strip 33 is connected to the extrusion strip 35, which is slidably connected to the extrusion port. The outer side of the protective strip 36 fixed to the outer side of the extrusion strip 35 has a pre-fixed arc-shaped elastic strip 39, and the height of the elastic strip 39 is greater than the height of the mounting base 31. Finally, the sunshade module 4 is assembled. Two symmetrical mounting pieces 41 are installed on the top of the distribution box 1. Sliding strips 42 are slidably connected to the surface of the mounting pieces 41. The top of the two sliding strips 42 is fixed with the same sunshade 43. The position of the sunshade 43 is adjusted so that the sliding strips 42 slide along the mounting pieces 41 to a suitable position. The sliding strips 42 are passed through by through posts 44 symmetrically arranged on one side of the mounting pieces 41. The locking caps 45 are threaded to the other end of the through posts 44 to fix the sliding strips 42 to the mounting pieces 41. Then, the closing caps are snapped on both ends of the mounting pieces 41 to prevent impurities from entering. After assembly, it is put into use. During use, the cooling fan 22 inside the mounting frame 21 in the heat dissipation module 2 is activated. The cooling fan 22 is connected to the heat dissipation vent 11 to accelerate the discharge of hot air from the power distribution box 1 through the heat dissipation vent 11. The filter screen 23 filters the air entering the cooling fan 22. The sunshade 43 in the sunshade module 4 blocks direct sunlight from hitting the top of the power distribution box 1 to reduce heat accumulation. If it is impacted externally, the elastic strip 39 on the outside of the protective strip 36 in the protection module 3 first contacts the impacting object and initially buffers the impact force through its own elastic deformation. Then, the protective strip 36 drives the compression strip 35 to compress the buffer air cushion 34 inside the hollow strip 33. The deformation of the buffer air cushion 34 further absorbs the impact force to achieve double protection. When maintenance is required, if the filter screen 23 needs to be cleaned or replaced, press the positioning post 26 to disengage it from the positioning port 24, and the filter screen 23 can be removed. After maintenance, reinstall it according to the original assembly method. To adjust the position of the sun visor 43, unscrew the locking cap 45, slide the slider 42 to the target position, and then tighten the locking cap 45 to fix it. To check the protective module 3, remove the sealing cover 38 to check the status of components such as the hollow strip 33 and the buffer air cushion 34. If it is necessary to replace the relevant components, release the snap-fit ​​between the snap-fit ​​strip 32 and the hollow strip 33 to replace them. After replacement, snap-fit ​​again and install the sealing cover 38.
