Description

Technical Field

[0001] This utility model relates to the field of battery protection technology, and in particular to a leakage protection tray. Background Technology

[0002] With the widespread application of batteries in industrial production, transportation, energy storage systems, and many other fields, their application scenarios are becoming increasingly complex and diverse, and the requirements for the environment in which batteries operate are constantly increasing. Among these, preventing battery leakage, particularly of electrolyte or acid, has become a crucial aspect of ensuring the safe and stable operation of batteries. Once a battery leaks, the leaked electrolyte is highly corrosive and easily adheres to the surface of the battery brackets nearby. This electrolyte not only severely corrodes the brackets themselves, reducing their structural strength and lifespan, but also corrodes and damages various electrical equipment adjacent to the battery, thus affecting the normal operation of the entire electrical system and potentially causing safety accidents. Based on this practical need, battery leak-proof trays have emerged to effectively catch any potential electrolyte leaks, preventing damage to surrounding equipment and the environment.

[0003] However, current battery trays on the market suffer from several problems that urgently need to be addressed. One type of battery tray uses a plastic structure, which, while offering advantages such as lightweightness, has significant drawbacks. First, plastic has relatively poor structural strength, making it difficult to withstand substantial external impacts and long-term loads, easily leading to deformation and damage in complex usage environments. Second, plastic trays typically require mold forming, and the development and manufacturing costs of these molds are high, increasing production costs and limiting rapid product iteration and customization. Furthermore, the properties of plastic make it unsuitable for pull-out installation and disassembly within sheet metal cabinets, causing considerable inconvenience in scenarios requiring frequent tray maintenance or replacement.

[0004] Another type of battery tray, while employing a sheet metal structure, suffers from design flaws. The excessive number of sheet metal components complicates installation, requiring significant manpower and time, increasing costs, and increasing the risk of improper installation affecting the tray's overall performance. Furthermore, the excessive number of components reduces overall reliability, making the tray prone to loosening and detachment during use, thus reducing its lifespan and safety. Moreover, most battery trays on the market use a single, integrated assembly structure, with the battery tightly connected to the tray, making separation difficult. When battery leakage occurs, all batteries on the tray must be removed to clean the leak. This design not only increases the difficulty and workload of cleaning leaks but may also cause secondary damage to the batteries during disassembly and installation, affecting their normal operation.

[0005] In conclusion, given the numerous problems existing in current battery trays, it is particularly necessary and urgent to improve and innovate existing technologies in order to meet market demands for safe and efficient use of batteries, improve the performance and quality of battery trays, and reduce usage costs and maintenance difficulties.

[0034] Support plate 1, liquid receiving tray 2, support plate 3, leakage hole 4, placement space 5, battery 6. Detailed Implementation

[0035] 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.

[0036] Please refer to Figure 1-5 This utility model embodiment provides a leakage protection tray, mainly used to support a battery 6. The overall structure of the tray consists of several key components, specifically including a support plate 1, a drip tray 2, and two support plates 3.

[0037] From a manufacturing process perspective, both the support plate 1 and the drip tray 2 are formed using sheet metal processing. Sheet metal processing is a widely used process in the manufacturing of metal products, and components manufactured using this process possess many excellent characteristics. The support plate 1 has a hollow internal structure with an open top, providing ample space for placing the battery 6. Simultaneously, drainage holes 4 are intentionally provided at the bottom of the support plate 1. When the battery 6 leaks, the leaking liquid can flow out smoothly through these drainage holes 4, preventing accumulation inside the support plate 1 and thus reducing further damage to the battery 6 and corrosion of the support plate 1 itself.

[0038] The two support plates 3 play a crucial supporting and positioning role in the structure of the leakage protection tray. They are located on both sides of the support plate 1 and both adopt an L-shaped design. This unique L-shaped structure not only provides stable support for the support plate 1, ensuring its stability when carrying the battery 6 and preventing it from shaking or tilting, but also forms a dedicated placement space 5 between the two support plates 3. The size and shape of this placement space 5 are adapted to the support plate 1, accurately accommodating it and further enhancing the stability and compactness of the entire tray structure.

[0039] The drip tray 2 plays a crucial role in catching leaks within the leak protection tray. It is positioned below the bottom of the support plate 1 and is movably installed within the placement space 5. This movable design greatly enhances the convenience of use. When cleaning leaks from the tray, it is not necessary to completely remove the batteries 6 from the support plate 1; simply pulling the drip tray 2 out of the placement space 5 allows for easy cleaning, significantly reducing the difficulty and workload of the cleaning process. Simultaneously, it effectively prevents secondary damage to the batteries 6 during frequent disassembly and reassembly, ensuring the safety and normal operation of the batteries 6.

[0040] The leakage protection tray provided in this embodiment of the invention has significant advantages in structural performance due to its sheet metal support plate 1 and drip tray 2. Compared with traditional plastic trays, the sheet metal support plate 1 and drip tray 2 have higher structural strength, can withstand greater external impacts and long-term usage loads, and are less prone to deformation and damage. Moreover, sheet metal has stronger corrosion resistance, allowing it to be used for a long time under various complex environmental conditions without corrosion, thus greatly extending the service life of the tray and effectively solving the problems of poor strength, easy damage, and weak corrosion resistance of existing plastic trays.

[0041] In terms of structural design, this embodiment of the invention optimizes the leakage protection pallet. Through a rational design, the number of sheet metal parts is reduced, making the overall pallet structure simpler and clearer. This not only simplifies the installation process and reduces installation costs, but also reduces performance problems that may result from improper installation, improving the overall reliability and service life of the pallet. Simultaneously, this optimized structural design also makes the pallet more efficient in the manufacturing process, contributing to increased production efficiency and reduced production costs.

[0042] Furthermore, the design of the drip tray 2 being movably mounted in the placement space 5 greatly facilitates leak cleaning. In actual use, when the battery 6 leaks, operators do not need to perform cumbersome battery disassembly; they can simply pull out the drip tray 2 for cleaning, significantly saving time and labor costs. Moreover, it avoids secondary damage to the battery 6 that may be caused by collisions or scratches during disassembly and installation, further improving the safety and efficiency of the battery 6.

[0043] Meanwhile, the L-shaped support plate 3 provides stable and reliable support for the support plate 1. Its unique shape and structure effectively distribute the pressure on the support plate 1, ensuring that the support plate 1 remains stable when carrying the battery 6, and is not prone to shaking or tilting. This stable support structure further enhances the stability of the entire leakage protection tray, enabling the tray to work reliably in various usage scenarios.

[0044] In summary, the leakage protection tray provided by this utility model embodiment has significant advantages in improving battery safety, reducing maintenance costs, and enhancing ease of use. It effectively solves many problems existing in current battery trays, meets the market's urgent demand for safe and efficient use of batteries, and has broad market application prospects and promotional value.

[0045] In one embodiment of this example, in order to ensure that the liquid receiving tray 2 can work stably and reliably within the placement space 5, and to avoid accidental sliding or displacement of the liquid receiving tray 2 during normal use or movement of the tray, thereby affecting its liquid receiving effect, a fixing component is specially provided between the liquid receiving tray 2 and the support plate 1 or the support plate 3 to firmly fix the liquid receiving tray 2.

[0046] The following are two exemplary methods for setting up fixed components:

[0047] Firstly, the fixing assembly uses a combination of bolts and nuts. Specifically, through holes of appropriate specifications are pre-drilled on the drip tray 2, support plate 1, or support plate 3. The position and number of these through holes need to be precisely determined according to the actual structural design and fixing requirements. When it is necessary to fix the drip tray 2, the bolts are passed through the corresponding through holes on the drip tray 2 and support plate 1 or support plate 3 in sequence. Then, nuts are installed on the other end of the bolts, and the nuts are tightened with a suitable tool (such as a wrench) to generate sufficient preload between the bolt and the nut, thereby firmly fixing the drip tray 2 to the support plate 1 or support plate 3. This fixing method has the advantages of firm fixation and high reliability, and can withstand greater external forces, ensuring that the drip tray 2 remains stable in various complex operating environments. Moreover, bolts and nuts are common standard parts, easy to purchase and replace, and have low maintenance costs. At the same time, by adjusting the tightening degree of the nuts, the fixing tightness of the drip tray 2 can also be adjusted to a certain extent to meet different usage requirements.

[0048] Secondly, the fixing components employ a combination of snap-fit ​​and slot-locking mechanisms. Snap-fits are located at the edge of the drip tray 2, while corresponding slots are provided on the support plate 1 or support plate 3 to match the snap-fits. The shape and structure of the snap-fits must ensure they can smoothly engage in the slots and generate sufficient clamping force to prevent the drip tray 2 from easily dislodging. When installing the drip tray 2, simply align the snap-fits on the drip tray 2 with the slots on the support plate 1 or support plate 3, and apply pressure to engage the snap-fits, thus quickly fixing the drip tray 2. This fixing method is simple and quick to operate, requiring no additional tools and greatly improving installation and disassembly efficiency. Especially when frequent cleaning of leaks in the drip tray 2 is required, this quick-installation and disassembly method saves significant time and labor costs. Moreover, the snap-fit ​​and slot design is relatively simple, occupies little space, and does not significantly affect the overall structure of the tray, contributing to maintaining the tray's compactness and aesthetics.

[0049] By setting the above two exemplary fixing components, the appropriate fixing method can be flexibly selected according to the actual usage scenario and needs, ensuring that the liquid receiving tray 2 always maintains a stable and reliable working state in the leakage protection tray.

[0050] In one embodiment of this invention, to further optimize the leakage protection tray's effect on handling leakage, the leakage holes 4 at the bottom of the support plate 1 are not single, but multiple. Furthermore, these multiple leakage holes 4 are arranged in an array according to a specific pattern.

[0051] From a structural perspective, the arrayed distribution of leakage holes 4 offers several significant advantages. Firstly, this distribution ensures that leakage flows evenly out of the bottom of the support plate 1. When the battery 6 leaks, the leaked electrolyte is evenly distributed across each leakage hole 4 and flows smoothly into the receiving tray 2 below. Compared to single or randomly distributed leakage holes, the array distribution avoids situations where leakage holes are too densely or sparsely distributed in certain areas. If the leakage holes are unevenly distributed, electrolyte may flow out rapidly in densely packed areas, while sparsely packed areas are prone to accumulating liquid. This accumulation can cause localized corrosion to the bottom of the support plate 1 and may also lead to other safety hazards due to prolonged electrolyte buildup, such as short circuits. The arrayed distribution of multiple leakage holes 4 used in this embodiment effectively prevents such localized liquid accumulation, ensuring that leakage flows comprehensively and evenly into the receiving tray 2.

[0052] Secondly, the array distribution design of multiple leakage holes 4 also takes into account the handling capacity when the leakage volume is large. In actual use, the leakage situation of battery 6 may vary due to various factors, and sometimes the leakage volume may be large. If the number of leakage holes is too small or the distribution is unreasonable, when the leakage volume is large, the electrolyte may not be able to flow into the receiving tray 2 in time through the leakage holes 4, resulting in the electrolyte accumulating in the support tray 1, or even overflowing the support tray 1, causing damage to surrounding equipment and the environment. In this embodiment, the arrangement of multiple leakage holes 4 in an array can increase the leakage flow area and improve the leakage handling efficiency. Even when the leakage volume is large, it can ensure that the electrolyte flows into the receiving tray 2 quickly and smoothly, avoiding the problems of accumulation and overflow.

[0053] Furthermore, from a manufacturing process and cost perspective, the design of multiple drainage holes 4 arranged in an array is also reasonable. During sheet metal processing, the array of drainage holes 4 can be easily fabricated through proper mold design and processing techniques. Moreover, this design does not significantly increase manufacturing costs while improving the performance and quality of the pallet, offering high cost-effectiveness.

[0054] In summary, designing multiple leakage holes 4 in an array in this embodiment is a scientifically sound and reasonable design. It effectively ensures that leakage flows evenly into the receiving tray, avoiding localized liquid accumulation and improving the tray's ability to handle leakage and its safety.

[0055] In one embodiment of this invention, the L-shaped structure of the support plate 3 is designed in greater detail. The L-shaped structure of the support plate 3 includes a vertical portion and a horizontal portion.

[0056] From a structural connection perspective, the vertical section plays a crucial role in connecting to the side wall of the support plate 1. During design and installation, the connection between the vertical section and the side wall of the support plate 1 must be robust and reliable to stably withstand the weight of the support plate 1 and the battery 6 it carries, as well as various external forces that may occur during the use of the tray. A common connection method is welding, where the vertical section is firmly welded to the side wall of the support plate 1. This method offers advantages such as high strength and good sealing, ensuring that the connection is not easily loosened or detached during long-term use. Alternatively, a bolted connection can be used. Corresponding through holes are pre-drilled in the vertical section and the side wall of the support plate 1, and then bolts and nuts are used to secure them tightly. This method facilitates disassembly and installation, allowing for quick operation and improved work efficiency when the liquid-resistant tray needs maintenance or component replacement.

[0057] The horizontal section is perpendicular to the vertical section. This vertical relationship is carefully designed to ensure the stability and rationality of the overall structure of the support plate 3. The horizontal section extends into the placement space 5, and its length and width need to be precisely determined according to the size of the support plate 1, the specifications of the battery 6, and the overall design requirements of the tray. The extension of the horizontal section into the placement space 5 provides additional support for the support plate 1, forming a stable support system together with the vertical section, further enhancing the load-bearing capacity of the support plate 1, allowing it to be placed more stably in the placement space 5, and preventing it from shaking or tilting. On the other hand, the extension design of the horizontal section can also limit the horizontal movement of the support plate 1 to a certain extent, preventing the support plate 1 from leaving the placement space 5 when the tray moves or is subjected to external impact, thereby ensuring the integrity and stability of the entire leakage protection tray structure.

[0058] Furthermore, the L-shaped structure design of the support plate 3 also takes into account the rationality of material utilization and cost factors. By optimizing the dimensions and shape of the vertical and horizontal sections, the amount of material used can be minimized to reduce manufacturing costs while meeting the structural strength and usage requirements of the pallet. At the same time, this L-shaped structure design also facilitates sheet metal processing, improves processing efficiency during production, and ensures the consistency and stability of product quality.

[0059] In summary, the L-shaped structure of the support plate 3 in this embodiment is designed with such meticulous care, taking into account multiple aspects such as structural connection, support function, stability, cost, and processing, so that the support plate 3 can better play its role in the leakage protection tray.

[0060] In one embodiment of this invention, to comprehensively enhance the leakage control capability of the leakage protection tray, a sealing ring is carefully provided on the edge of the drip tray 2. The selection of the material for this sealing ring is crucial; typically, high-quality materials with good elasticity, chemical corrosion resistance, and sealing performance, such as rubber, are chosen. Rubber sealing rings can adapt to joints of different shapes and sizes to a certain extent, and their good elasticity ensures a tight fit to the contact surface when compressed, forming an effective sealing barrier. Simultaneously, their chemical corrosion resistance ensures that they will not corrode or age when in prolonged contact with electrolytes and other chemicals in battery leakage, thus guaranteeing the durability of the sealing effect.

[0061] From the installation position, the sealing ring fits tightly against the edge of the drip tray 2. It can be installed by directly fitting it into a pre-designed groove on the edge of the drip tray 2, or by firmly attaching it to the edge of the drip tray 2 with adhesive. Regardless of the installation method, it is essential to ensure that the sealing ring is securely installed and will not loosen or fall off during the use of the tray.

[0062] When the drip tray 2 is placed on the horizontal part of the support plate 3, the sealing ring comes into contact with the horizontal part. This contact is not a simple surface contact, but rather a tight fit is formed between the sealing ring and the horizontal part through the elastic deformation of the sealing ring itself. Specifically, after the drip tray 2 is in place, the sealing ring undergoes a certain degree of elastic compression deformation under the pressure of the drip tray 2's own weight and any external pressure, thereby filling the tiny gap between the drip tray 2 and the horizontal part. This tight fit effectively prevents leakage from overflowing from the gap between the drip tray 2 and the horizontal part.

[0063] From a deeper analysis of the sealing principle, the seal between the sealing ring and the horizontal part is a contact seal. At a microscopic level, the surfaces of the sealing ring and the horizontal part are not completely flat, but rather have a certain degree of roughness. When they come into contact and are subjected to pressure, the microscopic protrusions on the surface of the sealing ring embed into the microscopic depressions on the surface of the horizontal part, forming a kind of "biting" state, which greatly increases the resistance to leakage. At the same time, the elasticity of the sealing ring allows it to maintain tight contact with the horizontal part under pressure. Even if the tray experiences slight vibration or shaking during use, the sealing ring can quickly adjust its shape to continue maintaining a good sealing effect.

[0064] Further improving the leakage protection effect is an important purpose of installing this sealing ring. In actual use, the leakage of battery 6 may vary due to various factors; sometimes the leakage volume may be large, or the leakage rate may be fast. Without the sealing effect of the sealing ring, leakage may quickly overflow from the gap between the drip tray 2 and the horizontal part, which may not only damage the equipment and environment around the tray, but also cause safety hazards such as short circuits and fires. The sealing ring effectively prevents this from happening, firmly controlling the leakage within the drip tray 2, and facilitating subsequent leakage handling and cleaning.

[0065] In addition, the sealing ring also has a certain shock absorption and cushioning effect. When the pallet moves or is subjected to external impact, the sealing ring can absorb some energy, reducing the impact force between the drip tray 2 and the horizontal part, thereby protecting the drip tray 2 and the support plate 3 from damage and extending the service life of the pallet.

[0066] In summary, the design of setting a sealing ring at the edge of the liquid receiving tray 2 and having it contact the horizontal part in this embodiment is a scientifically sound and effective sealing solution. It can improve the performance of the leakage protection tray in multiple ways.

[0067] In one embodiment of this invention, to ensure the safe placement of the battery 6 on the support plate 1, a protective railing is carefully installed at the top edge of the support plate 1. The design and installation of this protective railing were determined after comprehensive consideration of various factors, including the usage scenarios, size specifications, and potential external forces affecting the battery 6.

[0068] In terms of material selection for guardrails, materials with high strength and good toughness are typically chosen, such as stainless steel or high-strength engineering plastics. Stainless steel guardrails offer advantages such as high strength, corrosion resistance, and long service life, maintaining stable performance under various complex environmental conditions. They are not prone to rust or damage, providing long-term reliable protection for the battery. High-strength engineering plastic guardrails, on the other hand, are lightweight, low-cost, and have good insulation properties, offering unique advantages in applications with high weight and insulation requirements.

[0069] The structural design of the protective barrier is also crucial. It can employ a continuous fence-like structure, where a continuous ring of bars surrounds the top edge of the support plate 1. This structure forms a complete protective barrier, preventing the battery 6 from sliding out of the support plate 1 from any direction. The fence-like structure can be solid or a perforated design with gaps. Solid bars offer higher strength and protective performance, capable of withstanding greater external impacts; perforated designs, while maintaining protective effectiveness, reduce the weight of the protective barrier, lower manufacturing costs, and also facilitate observation of the battery 6's position within the support plate 1.

[0070] Another common structural design is the spaced-out guardrail, which involves setting multiple independent guardrail posts at regular intervals along the top edge of the support plate 1. This design, while fulfilling basic protective functions, places greater emphasis on ventilation and heat dissipation. For batteries 6, which generate significant heat during operation, the spaced-out guardrail allows for better airflow around them, aiding in heat dissipation and improving battery performance and lifespan. Furthermore, the spaced-out guardrail is relatively easy to install and remove, facilitating maintenance and replacement of the batteries 6.

[0071] The installation method of the guardrail must also ensure its firmness and reliability. Welding can be used to fix the guardrail to the top edge of the support plate 1. This connection method has high strength and can withstand greater external forces, making it suitable for scenarios with high protection requirements. Alternatively, bolted connections can be used. Corresponding through holes are pre-drilled in both the support plate 1 and the guardrail, and then bolts and nuts are used to secure them tightly. Bolted connections facilitate disassembly and installation, allowing for quick operation when maintenance or replacement of the guardrail is needed, thus improving work efficiency.

[0072] From a protective principle perspective, the guardrail primarily prevents the battery 6 from sliding off the support plate 1 through physical obstruction. When the battery 6 is subjected to vibration, tilting, or external force on the support plate 1, the guardrail forms an effective barrier, limiting the range of movement of the battery 6 and preventing it from sliding off the support plate 1 and causing damage or a safety accident. For example, during pallet transportation, the vehicle may experience bumps or sudden braking; in such cases, the guardrail can prevent the battery 6 from sliding off the support plate 1 due to inertia, ensuring the battery 6 is securely fixed.

[0073] In summary, the design of providing a protective railing at the top edge of the support plate 1 in this embodiment is a scientifically sound and essential protective measure. It can ensure the safe fixation of the battery 6 on the support plate 1 from multiple aspects.

[0074] In one embodiment of this invention, to further optimize the collection and treatment capacity of the drip tray 2 for leaked liquid, at least one guide channel is carefully provided at the bottom of the drip tray 2. The number of guide channels can be reasonably determined based on factors such as the actual size of the drip tray 2, the expected leakage volume, and design requirements. When the drip tray 2 is small in size and the expected leakage volume is small, one guide channel is sufficient to meet the basic requirements; while for a larger drip tray 2 that may face a larger leakage volume, multiple guide channels can be provided to guide the leakage more efficiently.

[0075] From the shape design of the guide channel, it extends regularly from the center area of ​​the liquid receiving tray 2 towards the edge. A common design is a straight line, which is simple, easy to manufacture, and guides the leaked liquid from the center to the edge via the most direct path. The width and depth of the straight guide channel can be adjusted according to actual conditions. Generally, the greater the width and depth, the stronger its guiding capacity, but it will also correspondingly increase the weight and manufacturing cost of the liquid receiving tray 2. Besides the straight line, the guide channel can also be designed as an arc or a spiral. An arc-shaped guide channel allows the leaked liquid to flow more smoothly and reduces flow resistance; a spiral guide channel can increase the length of the guiding path within a limited space, further enhancing the guiding effect.

[0076] The layout of the guide channels at the bottom of the receiving tray 2 is also very important. Multiple guide channels can be evenly distributed radially at the bottom of the receiving tray 2. This layout ensures that the leakage flowing from the central area can be evenly distributed into each guide channel, preventing overflow of local guide channels due to excessive leakage. At the same time, the radial layout also allows the leakage to collect more quickly into the liquid collection tank at the edge.

[0077] From a deeper analysis of the flow guiding principle, when battery 6 leaks, the leaked liquid first drips into the central area of ​​the receiving tray 2. Due to gravity, the leaked liquid will naturally flow downwards into the guide channel. The bottom of the guide channel is usually designed with a certain slope, which provides the force for the leaked liquid to flow towards the edge, allowing it to flow smoothly along the guide channel to the liquid collection tank at the edge. During the flow process, the side walls of the guide channel guide and constrain the leaked liquid, preventing it from spreading. When the leaked liquid reaches the liquid collection tank, it will be collected for subsequent centralized treatment.

[0078] This design, featuring a diversion channel and a liquid collection tank, offers several significant advantages. First, it improves the efficiency of leak handling. Guided by the diversion channel, the leak quickly and accurately converges into the collection tank, preventing large-scale accumulation at the bottom of the receiving tray 2 and reducing the workload and time required for cleanup. Second, it facilitates centralized leak treatment. Once the leak is collected in the collection tank, it can be easily removed using suction equipment or manual cleaning for proper disposal, reducing the risk of environmental pollution.

[0079] Although this invention frequently uses terms such as support plate, drip tray, and support plate, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.

[0080] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this utility model, this should not limit the scope of patent protection of this utility model. Any technical solutions resulting from equivalent structural or procedural substitutions or modifications made based on the essential concept of this utility model and utilizing the content described in the text and drawings of this utility model, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this utility model.
