[0027] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings. The illustrative implementation methods and descriptions of the embodiments of this disclosure are only used to explain the embodiments of this disclosure and are not intended to limit the embodiments of this disclosure.

[0028] like Figure 1 and Figure 2 As shown, the distribution box protection structure and distribution box of this application include several key components, namely, the box body 1, the locking mechanism 2, the reinforcing frame 3, the buffer assembly 4, and the connecting plate 5. Through the design and assembly of these components, the vibration resistance and protection capability of the distribution box can be effectively improved.

[0029] Enclosure 1 houses the electrical components and provides external protection. It is made of high-strength steel, offering strong corrosion resistance and excellent sealing. It is integrally formed using welding or bending techniques. During manufacturing, cable interface positions can be pre-defined and rubber gaskets installed to ensure waterproofing and dustproofing. Furthermore, the surface of enclosure 1 is typically treated with electrostatic spraying to enhance wear resistance and oxidation resistance.

[0030] The locking mechanism 2 is located on one side of the enclosure 1 and mainly provides a reliable locking function for the enclosure door. The locking mechanism 2 consists of a welded fixing point 21, reinforcing ribs 22, and a vibration-damping end 23 (see details). Figure 3The fixing points are connected to the housing 1 via precision spot welding, ensuring sufficient connection strength to withstand vibration stress. To adapt to varying operating conditions, the reinforcing ribs 22 are porous, reducing weight and effectively dispersing external pressure. Simultaneously, the integrated vibration-damping end 23 reduces fatigue damage caused by long-term high-frequency vibration. In practical implementation, the locking mechanism 2 achieves secure locking through a mechanical pin and double-layer locking rod.

[0031] The reinforcing frame 3 is fixedly installed around the exterior of the entire enclosure 1, primarily to enhance the rigidity and stability of the overall device. The reinforcing frame 3 is typically constructed of stainless steel profiles and employs a modular design concept for easy assembly and disassembly. It achieves rapid assembly through a secure fit between bolts and positioning holes on the enclosure 1. To ensure tight contact at the joints and prevent slippage or loosening, the shaping deviation of each frame component is strictly controlled during the manufacturing stage, and a material with an increased shear friction coefficient is applied as an auxiliary protection measure.

[0032] The buffer assembly 4 is installed between the locking mechanism 2 and the reinforcing frame 3 to absorb impact energy, thereby reducing the vibration force transmitted to the internal equipment. This assembly mainly relies on the properties of high-molecular elastic materials, possessing the ability to recover its original shape after compression deformation. For ease of installation and commissioning, a unique elastic slot connection structure is designed so that the buffer assembly 4 can be easily inserted into the designated position to complete the pre-assembly. In terms of specific technical implementation, a block material made of polyurethane foam is selected to meet the requirements of different load levels and maintain dimensional stability over a long period of time.

[0033] Connecting plate 5 acts as a bridge, linking the reinforced frame 3 and the buffer assembly 4 subsystems. Connecting plate 5 itself undergoes a hardening treatment to prevent brittle fracture and is then securely fixed to the designated area using a professional riveting machine. It plays a crucial role in evenly distributing loads along the force transmission path; for example, optimized angle design ensures more reasonable force distribution, avoiding the risk of failure due to localized overload.

[0034] The above-mentioned technical features address the problem of vibration in harsh environments as follows: First, the locking mechanism 2 reduces the risk of component displacement and detachment caused by external forces by combining an enhanced fixing method with an anti-vibration end; second, the buffer component 4 directly isolates most of the harmful vibrations from entering the core circuit area; and third, the connecting plate 5 is used to balance the forces in all directions to further strengthen the overall robustness of the system.

[0035] like Figure 3As shown, in one embodiment, the distribution box protection structure and the locking mechanism 2 of the distribution box of this application are firmly fixed by welding, further improving the reliability of the connection. Specifically, the welding fixing points 21 used to connect the locking mechanism 2 and the box body 1 are distributed in a multi-point array to expand the stress-bearing area and disperse the risk of stress concentration. This multi-point array design makes the weld more stable and reliable when subjected to impact loads or vibrations. At the same time, high-strength corrosion-resistant material is added to each welded part to strengthen the overall performance of the welded area, which can effectively improve the vulnerability of traditional single-point or linear welding and significantly extend the service life of the protective structure.

[0036] For example, a nickel-based alloy can be selected as the filler material, and the locking mechanism 2 can be precisely welded to one side of the housing 1 using automated welding technology. During the welding process, each weld point is formed sequentially according to a pre-set multi-point array coordinate system, while ensuring that high-strength, corrosion-resistant material is uniformly filled in the fusion area. This method can enhance local rigidity without affecting the integrity of the appearance, meeting the application requirements in complex environments.

[0037] like Figure 3 As shown, in one embodiment, the distribution box protection structure and locking mechanism 2 of this application improve the overall vibration resistance through a unique design. Specifically, the reinforcing ribs 22 adopt a special structure of staggered multi-layer stacking. In actual use, this design not only enhances the rigidity of local areas of the locking mechanism 2, but also improves the stress distribution characteristics, making it more suitable for withstanding complex mechanical actions under dynamic loads and vibration environments. Meanwhile, to further optimize its performance, embedded reinforcing strips 24 are cleverly arranged inside the reinforcing ribs 22, forming a tightly fitted whole with the ribs. The presence of embedded reinforcing strips 24 effectively compensates for the weaknesses of the reinforcing rib material in terms of tensile or torsional strength, thereby significantly improving the overall mechanical properties of the component.

[0038] For example, during manufacturing, the reinforcing ribs 22 can be pressed into a predetermined staggered multi-layered structure using a mold. Then, slots are pre-drilled at designated locations for the embedded reinforcing strips 24. Finally, the two are joined using methods such as gluing or interference fit. After connection, the entire assembly can be welded to the side of the housing 1 and work in conjunction with other components such as the vibration-damping end caps 23. This assembly method ensures structural consistency and facilitates mass production.

[0039] like Figure 3As shown, in one embodiment, an auxiliary fixing buckle 25 is provided between the anti-vibration end 23 and the box body 1 of the distribution box protective structure of this application. The auxiliary fixing buckle 25 is arranged at the position of the anti-vibration end 23 near the box body 1, mainly to disperse stress. The stress generated during the locking operation may be concentrated in the connection area. If this force is not effectively dispersed, it may lead to local material fatigue or connection failure. The auxiliary fixing buckle 25, by acting directly on the connection part between the anti-vibration end 23 and the box body 1, can transform the concentrated stress into small-amplitude dispersed forces in multiple directions during the force process, thereby significantly improving the connection strength and durability.

[0040] Specifically, the auxiliary fixing clip 25 is installed by embedding one end into the side opening groove of the anti-vibration end 23 near the housing 1, and fixing the other end to the surface of the housing 1 through press fitting or other reliable mechanical connection, forming a stable three-point contact structure. For example, in practical design, a flexible claw-shaped structure can be used to fix the clip to the housing 1, and the material properties of the anti-vibration end 23 (such as metal alloy) can be used to ensure sufficient rigidity and flexibility in the connection. The specific shape of the auxiliary fixing clip 25 can be adjusted according to the connection position and size of the housing 1 and the anti-vibration end 23 to meet the needs of different application scenarios.

[0041] like Figure 2 and Figure 3 As shown, in one embodiment, the technical features of the distribution box protection structure and distribution box of this application are reflected in the design of further optimizing the connection stability between the locking mechanism 2 and the box body 1. Specifically, to address the vibration problem that may occur during operation, a specific silicone anti-slip pad 6 structure is added between the locking mechanism 2 and the box body 1. The silicone anti-slip pad 6 is located on the outside of the box body 1 at the installation position corresponding to the locking mechanism 2, and completely covers the contact surface of the two. The silicone anti-slip pad 6 is made of silicone material with excellent elasticity and anti-aging properties, and the surface is textured or dotted to enhance friction. Through this design, the risk of component loosening due to long-term use can be effectively reduced.

[0042] Specifically, the silicone anti-slip pad 6 can be pre-attached to a predetermined position on the outside of the housing 1 or bonded to the bottom of the locking mechanism 2 during the production and assembly stage to ensure accurate alignment during assembly. For example, the installation position of the silicone anti-slip pad 6 can be standardized by setting precise positioning grooves or bonding areas, and then combined with traditional locking mechanism 2 fixing methods such as bolt tightening to complete the overall assembly process.

[0043] like Figures 2-4As shown, in one embodiment, a distribution box protective structure and a reinforcing frame 3 of the distribution box according to this application are provided with a vibration damping pad 7 at a position corresponding to the locking mechanism 2. The vibration damping pad 7 is made of elastic material and is installed in a designated area on the inner surface of the reinforcing frame 3 by bonding, snap-fitting, or integral molding. Its effective area directly faces the impact force source that may be transmitted to the outside of the distribution box, thereby effectively reducing the adverse effects of vibration or impact on the stability of the power distribution system. The design of the vibration damping pad 7 fully considers the random mechanical disturbances that may exist in the external environment and achieves force dispersion and absorption through reasonable spatial arrangement. Specifically, the vibration damping pad 7 is located on the inner edge of the reinforcing frame 3, adjacent to the working area of ​​the locking mechanism 2.

[0044] For example, when the locking mechanism 2 is impacted by an external force, the vibration damping pad 7 can absorb part of the impact energy through its own deformation and transfer the remaining force to the entire reinforcing frame 3 through the connecting plate 5, thus preventing concentrated force from damaging the critical parts of the locking mechanism 2. At this time, the buffer assembly 4 works in conjunction to further isolate additional vibrations from the core electrical components, ensuring system safety.

[0045] like Figure 5 As shown, in one embodiment, the distribution box protection structure and the buffer assembly 4 of the distribution box according to this application are made of double-layered rubber material. This design improves the vibration reduction effect by selecting a suitable rubber type and combining its multi-layered characteristics, while ensuring sufficient toughness in the actual environment to cope with the physical stress requirements of long-term use. In addition, the insertion of an elastic diaphragm 8 between the two layers of rubber further enhances the functional performance of the buffer assembly 4. Specifically, this combination can not only better absorb various forms of vibration energy transmitted from the outside, but also significantly reduce the damage caused by high-frequency impacts to key components inside the distribution box.

[0046] The design of the elastic diaphragm 8 allows each layer of rubber material to work synergistically, exhibiting superior vibration damping performance under various working conditions. The installation position is set between the locking mechanism 2 and the reinforcing frame 3, utilizing its naturally formed flexible transition area to effectively distribute external loads to the buffer assembly 4. Through reasonable matching connection methods such as elastic slots, the overall structure of the buffer assembly 4 is ensured to be tight and stable, facilitating subsequent maintenance. In terms of connection method, it is directly nested into relevant fixing points, and a specific process ensures that no displacement occurs.

[0047] For example, during the manufacturing process, two layers of rubber sheets with different hardness properties can be pre-selected and hot-pressed together. During processing, an elastic diaphragm 8 cut to the appropriate size and shape is sandwiched between the two sheets, and then uniformly cured to form a complete buffer component 4. During final assembly, it is precisely positioned within the specified range mentioned above.

[0048] like Figure 5 As shown, in one embodiment, an anti-detachment guard 9 is added between the distribution box protective structure and the elastic slot and locking mechanism 2 of the distribution box. The anti-detachment guard 9 is designed as a surrounding structure, located on one edge of the locking mechanism 2, and protrudes towards the reinforcing frame 3. This protruding structure can cover part of the outer area of ​​the elastic slot, forming a certain blocking effect. The presence of the anti-detachment guard 9 makes it difficult for the elastic slot to shift or detach when subjected to impact, thereby ensuring the connection reliability of the overall structure under vibration.

[0049] The anti-detachment guard 9 is made of a metal material with certain strength and toughness, and is fixed to the locking mechanism 2 by welding or integral molding. Specifically, its installation position is close to the fixing point of the locking mechanism 2, and it is in direct contact with the elastic groove in the buffer assembly 4. This structural design not only enhances local strength, but also improves the fit performance between components. For example, in the implementation process, assembly can be completed by pre-grooving and embedding the guard material, followed by further secure connection using the fixing point.

[0050] like Figure 4 As shown, in one embodiment, the distribution box protection structure and the connecting plate 5 of the distribution box of this application are optimized to balance the requirements of weight reduction and mechanical performance. As a key load-bearing component, the connecting plate 5 serves two purposes: firstly, it bears the external force applied by the reinforcing frame 3 and stably transmits it to the buffer assembly 4; secondly, it ensures that the overall distribution box structure maintains strength balance under complex working conditions. To achieve this, a special perforation design is implemented on the connecting plate 5 to reduce weight, improving transportation convenience and assembly efficiency while meeting functional requirements.

[0051] Specifically, by setting regularly distributed weight-reducing holes 10 on the connecting plate 5, combined with the edge curling process to form closed-loop reinforcing ribs, the stress concentration problem is effectively dispersed. The edge curling structure not only avoids the local crack propagation phenomenon that may occur in the material weakening area, but also increases the effective yield area of ​​the material to resist the influence of shear force and tensile load. This structural design is particularly suitable for distribution box scenarios in high vibration environments.

[0052] For example, cold-rolled steel sheet can be selected to make the connecting plate 5, and laser cutting technology can be used to precisely machine the weight-reducing holes 10. Subsequently, the edges are rolled using a hydraulic mold, thereby improving the toughness and rigidity of the sheet without adding extra weight. The connecting plate 5 is fixed to the reinforcing frame 3 with high-strength rivets, while reserved installation positions ensure reasonable torque distribution.

[0053] like Figure 4As shown, in one embodiment, the distribution box protection structure and the connecting plate 5 of the distribution box of this application enhance the connection stability with the reinforcing frame 3 by adding a reinforcing rib 11. Specifically, the reinforcing rib 11 is a reinforcing component, and its shape can be designed as a bent type, a flat type, or a grid type according to the stress between the connecting plate 5 and the reinforcing frame 3, thereby improving the overall connection strength. In actual installation, the reinforcing rib 11 is set on the side of the connecting plate 5 close to the reinforcing frame 3, and the three (connecting plate 5, reinforcing frame 3, and reinforcing rib 11) are firmly connected by riveting. This design avoids the connection loosening problem that may be caused by relying solely on riveting, and improves the tensile and shear resistance of the connection part.

[0054] For example, during the production process, reinforcing ribs 11 can be prefabricated according to the space constraints of the connection location, and then tightly attached between the connecting plate 5 and the reinforcing frame 3. Subsequently, special rivets are used to pass through each layer in sequence, ensuring sufficient clamping force to complete the fixation, thereby ensuring that the joint surfaces of the three are fully fitted. This structure is particularly suitable for distribution box protection systems that are exposed to vibration environments for extended periods.

[0055] In actual operation, when this device is in use, the enclosure 1 is used to house the power distribution components and provide them with necessary protection. The locking mechanism 2 is located on one side of the enclosure 1 to lock the door. The locking mechanism 2 enhances the impact resistance at the connection with the enclosure 1 through welded fixing points 21, multi-hole distributed reinforcing ribs 22, and integrated anti-vibration end 23 to meet the vibration requirements in harsh environments. The reinforcing frame 3 surrounds the outside of the enclosure 1 and is fixedly connected to the enclosure 1 with bolts, thereby improving the overall structural strength. The buffer assembly 4 is installed between the locking mechanism 2 and the reinforcing frame 3, which can effectively absorb external vibration and mitigate impact. It is connected to the locking mechanism 2 through elastic slots. The connecting plate 5 is connected to the reinforcing frame 3 and the buffer assembly 4 respectively, and is fixed to the reinforcing frame 3 by riveting, which plays a role in force transmission and ensures the stability of the overall structure. Through the cooperation between the components, the entire device effectively improves the safety and reliability of the power distribution box under complex working conditions.
