Technical Field

[0001] This utility model relates to the technical field of test trays, and more particularly to a test tray. Background Technology

[0002] With the rapid development of new energy vehicles and energy storage technologies, research on battery performance testing and its thermal management system is receiving increasing attention. Liquid cooling plates, as a crucial component of battery thermal management, effectively regulate battery temperature during operation, improving battery safety and lifespan. Testing the integration of batteries and liquid cooling plates typically requires a dedicated testing platform to monitor and analyze temperature changes in the battery under different operating conditions and the cooling effect of the liquid cooling plate.

[0003] However, in existing battery-liquid plate testing processes, the introduction and circulation of coolant inevitably lead to coolant leakage and overflow, especially during pipe connections or high-speed coolant flow, where water-cooling pipes can easily loosen or detach, causing coolant leaks. If this overflowing coolant is not collected and treated promptly and effectively, it will not only contaminate the testing environment and damage equipment but may also pose electrical safety risks, affecting the normal conduct of the test. Furthermore, existing test tray structures generally lack effective liquid collection and isolation functions, causing leaked coolant to spread to the test platform and surrounding areas, increasing cleanup workload and safety hazards.

[0004] Therefore, providing a test tray with a reasonable structure, efficient liquid collection capability, and stable pipeline function has become a key technical requirement for improving the safety, environmental cleanliness, and data reliability of battery and liquid cooling plate testing.

[0020] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings, clearly and comprehensively demonstrating the technical solution. It should be noted that the listed embodiments are only a part of this utility model, and not all possible implementations. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the structure of the test tray provided in this embodiment of the utility model. Figure 2 This is a cross-sectional schematic diagram of the test tray provided in an embodiment of the present invention. Figure 3 This is provided by the embodiment of the present utility model. Figure 2 A magnified view of a portion of region A in the middle.

[0022] This embodiment relates to a test tray for testing the interaction between a battery and a liquid cooling plate. The test tray comprises a base 10 and a robotic arm 20. The base 10 is the main body of the overall structure, and a receiving cavity 101 is provided inside the base 10. Multiple leakage holes 102 are also provided on the base 10, and these leakage holes 102 communicate with the receiving cavity 101. The side of the base 10 with the leakage holes 102 is specifically used to support the battery under test and the liquid cooling plate. During testing, by allowing coolant to circulate through the liquid cooling plate, the relationship between the battery's operating temperature and the cooling effect of the liquid cooling plate can be easily tested and analyzed. When coolant leakage or other liquid overflow occurs during testing, the overflowing liquid can flow smoothly through the leakage holes 102 on the base 10 into the receiving cavity 101 for centralized collection, preventing liquid from spreading outside the tray and ensuring a clean and safe testing environment.

[0023] The robotic arm 20 is connected to the base 10 and is designed to secure the water-cooling pipe. The water-cooling pipe is responsible for introducing coolant into the liquid cooling plate, thereby providing the necessary cooling conditions for the battery under test. During testing, due to the high flow rate of the coolant, impact forces are easily generated. If the water-cooling pipe is not securely secured, it can easily be blown away by the high-speed flowing liquid, causing coolant leakage. In this embodiment, the effective securing of the water-cooling pipe by the robotic arm 20 significantly enhances the stability and safety of the water-cooling pipe, preventing coolant leakage due to pipe loosening or detachment, further improving the safety and reliability of the test.

[0024] Through the above structural design, this technical solution effectively solves the technical problems of coolant overflow, environmental pollution, and safety hazards existing in the prior art during battery and liquid cooling plate testing. First, the multiple leakage holes 102 on the base 10 are connected to the receiving cavity 101, allowing for timely and efficient drainage and collection of any leaked coolant or other liquids into the receiving cavity 101, preventing liquid diffusion and ensuring the cleanliness and safety of the testing platform and surrounding environment. Second, the robotic arm 20 securely fixes the water-cooling pipes, preventing them from loosening or falling off due to high-speed coolant flow, effectively preventing safety risks and equipment damage caused by coolant overflow. Furthermore, this tray structure facilitates accurate measurement and observation of the relationship between battery operating temperature and liquid cooling plate cooling effect by testing personnel, improving testing efficiency and data reliability. Therefore, this technical solution, through the synergistic effect of the leakage collection structure of the base 10 and the water-cooling pipe fixing function of the robotic arm 20, achieves effective collection of coolant leaks, ensures a safe testing environment, and ensures stable and reliable testing processes, thus improving testing safety, convenience, and the accuracy of test data.

[0025] This embodiment provides an adjustable test tray, whose base 10 has a groove 121 along its width or length, and a robotic arm 20 is slidably connected to the groove 121. Specifically, the operator can move the robotic arm 20 to a suitable position along the groove 121 and fix it according to actual needs, achieving adaptation to water-cooled pipes of different lengths or liquid-cooled plates of different sizes. For example, when it is necessary to replace the water-cooled pipe with a longer or shorter one, simply slide the robotic arm 20 in the groove 121 to ensure that the water-cooled pipe is firmly fixed in the corresponding position, avoiding loosening or poor connection of the water-cooled pipe due to length mismatch. Similarly, when the size of the liquid-cooled plate changes, by adjusting the position of the robotic arm 20, the test tray can be adapted to liquid-cooled plates of different sizes, ensuring that the liquid-cooled plate can be firmly supported and positioned. The entire adjustment process is simple and quick, without the need to replace the tray or perform additional assembly operations, greatly improving the efficiency of experimental preparation and the flexibility of the testing process.

[0026] This technical solution significantly solves the problems of fixed structure and poor adaptability of existing test trays by creating a sliding groove 121 on the base 10 and allowing the robotic arm 20 to slide and adjust within the groove 121. Through this structure, the test tray can flexibly adjust the position of the robotic arm 20 according to the length of different water-cooling pipes and the size of the liquid-cooling plate, thereby achieving compatibility and adaptation to test objects of different specifications and improving the versatility and applicability of the tray. This not only avoids the cumbersome operation of frequently replacing the tray due to changes in the length of the water-cooling pipes or the size of the liquid-cooling plate, reducing maintenance costs, but also improves testing efficiency and experimental convenience. In summary, this technical solution, through structural innovation, enables the test tray to be quickly adjusted according to actual needs, solves the technical problem of insufficient adaptability of traditional trays, and achieves the technical effect of improving testing applicability and operational convenience.

[0027] This embodiment provides an adjustable limiting structure for a test tray. The base 10 of this structure has a slide groove 121, which consists of a first slide rail 122 and a second slide rail 123. The second slide rail 123 is located outside the first slide rail 122, and its height is lower than that of the first slide rail 122. One end of the robotic arm 20 has a slider 221, which is fitted into the first slide rail 122 and can partially extend out of the second slide rail 123. In practical applications, the slider 221 can slide and adjust simultaneously within both the first and second slide rails 122 and 123. Because the height of the second slide rail 123 is lower than that of the first slide rail 122, although the slider 221 can partially extend into the second slide rail 123, it is still entirely confined within the first slide rail 122, thus achieving a limiting effect. In operation, the user can push the robotic arm 20 to move the slider 221 along the slide rail, adjusting the position of the robotic arm 20 to suit different testing needs. Throughout the sliding process, the slider 221 remains within the constraint of the first slide rail 122 and will not separate from the slide rail 121 due to external force or improper operation. Furthermore, the structure of the slider 221 extending from the second slide rail 123 facilitates cooperation with other components or enables more flexible operation. This compact design and smooth adjustment process effectively improve the adaptability and safety of the test tray.

[0028] This technical solution cleverly solves the problems of easy detachment, unreliable limiting, and poor adaptability of the robot arm 20 adjustment structure in the prior art by setting a first slide rail 122 and a second slide rail 123 of different heights and cooperating with each other in the slide rail 121, and by using a slider 221 limiting structure. The slider 221 can slide simultaneously in the first slide rail 122 and the second slide rail 123, which not only ensures the flexibility of the robot arm 20 adjustment, but also, through the wrapping and limiting effect of the first slide rail 122 on the slider 221, resolutely prevents the slider 221 from detaching from the slide rail 121, ensuring the stability and safety of the structure. The setting of the second slide rail 123 allows the slider 221 to extend partially, which facilitates subsequent operation and component cooperation, and improves the practicality of the structure. In summary, this technical solution, through structural innovation, achieves adjustable and reliable limiting of the test pallet robot arm 20, effectively improving the convenience of operation, safety, and universal adaptability of the pallet, thereby achieving the technical effects of preventing the robot arm 20 from detaching, improving testing efficiency, and structural reliability.

[0029] This embodiment relates to a robotic arm 20 structure suitable for a battery temperature testing device. As shown in the figure, the robotic arm 20 includes a first arm 22 and a second arm 23. One end of the first arm 22 is connected to the base 10 and can be slidably connected to the base 10. The other end is rotatably connected to the second arm 23 through a rotating connector. Specifically, the rotating connector can be a shaft, hinge, or other mechanical structure capable of rotational movement, allowing the second arm 23 to rotate relative to the first arm 22 within a certain range. The free end of the second arm 23 is used to support or fix the water-cooling tube. By adjusting the rotation angle of the second arm 23, the height and spatial position of the water-cooling tube can be flexibly changed, maintaining a reasonable gap between the water-cooling tube and the battery under test. During operation, the user can manually rotate the second arm 23 according to different battery sizes and testing requirements to adjust the water-cooling tube to a suitable height, avoiding direct contact between the water-cooling tube and the battery under test. After adjustment, the second arm 23 can be fixed in the target position using a locking device (such as screws, clips, etc.) to ensure structural stability during the testing process.

[0030] This technical solution achieves flexible adjustment of the water-cooling tube height by using a rotating connection between the first arm 22 and the second arm 23 within the robotic arm 20 structure. In existing technologies, if the water-cooling tube height is not adjustable, it is prone to direct contact with the battery under test, leading to abnormal heat conduction and affecting the accuracy of temperature testing. This solution, through the adjustment function of the second arm 23, effectively avoids direct contact between the water-cooling tube and the battery under test, thus ensuring the consistency of the testing environment and the accuracy of temperature measurement results. Furthermore, the rotating connection structure allows the device to adapt to batteries of different models and sizes, improving the versatility and adaptability of the testing device. Therefore, this technical solution solves the technical problem of existing temperature testing devices being unable to flexibly adjust the water-cooling tube height, which easily causes testing errors, achieving the technical effects of adjustable water-cooling tube height, guaranteed testing accuracy, and device adaptability.

[0031] This embodiment provides a robotic arm 20 structure for adjusting the height of a water-cooled pipe. The second arm 23 in this structure includes a first rod 231, a second rod 232, and a fixing member 233. Specifically, one end of the first rod 231 is rotatably connected to the first arm 22 via a rotating connector, allowing the first rod 231 to rotate around the connection point of the first arm 22, thereby adjusting the overall orientation of the second arm 23. The first rod 231 and the second rod 232 are slidably connected along their length, meaning the second rod 232 can freely extend and retract along the length of the first rod 231, adjusting the total length of the second arm 23 to adapt to different usage requirements. The fixing member 233 is connected to the first rod 231 and the second rod 232 respectively, and is fixed in their current relative position by tightening or locking, preventing accidental displacement of the sliding components during operation. This structure allows users to flexibly adjust the spatial position and length of the second arm 23 through rotation and extension, thereby precisely adjusting the installation height and position of the water-cooled pipe.

[0032] This technical solution achieves adjustable length and flexible spatial positioning of the robotic arm 20 by using a sliding connection between the first rod 231 and the second rod 232 in the second arm 23, and the limiting and fixing function of the fixing component 233. Traditional water-cooled pipe support structures are mostly fixed or non-adjustable in length, which can easily lead to unreasonable gaps between the water-cooled pipe and the battery under test, or even direct contact, affecting the accuracy of temperature testing. This solution achieves adjustment of the water-cooled pipe's orientation through the rotational connection between the first rod 231 and the first arm 22; and achieves multi-level adjustment of height and length through the sliding connection between the first rod 231 and the second rod 232 and the locking of the fixing component 233. This allows the water-cooled pipe to be precisely positioned according to different battery sizes and layout requirements, avoiding direct contact between the water-cooled pipe and the battery, and effectively ensuring the authenticity and reliability of temperature testing. Therefore, it solves the technical problems of inconvenient adjustment, poor adaptability, and easy interference with test results in existing water-cooled pipe support structures, achieving flexible adjustment of the water-cooled pipe's height and position, improving the accuracy of temperature testing and the versatility of the device.

[0033] This embodiment provides a robotic arm 20 structure for fixing water-cooled pipes, as shown in the figure. The robotic arm 20 includes a first fixing sleeve 24, a second fixing sleeve 25, and fasteners 26. The first fixing sleeve 24 is connected to one end of a second arm 23, and the second fixing sleeve 25 is connected to one end of the second arm 23. During installation, the first fixing sleeve 24 and the second fixing sleeve 25 are mated together to form a through-hole. The diameter of this through-hole matches the outer diameter of the water-cooled pipe, used for inserting and fixing the water-cooled pipe. Fasteners 26 (such as screws, bolts, etc.) are connected to the first fixing sleeve 24 and the second fixing sleeve 25 respectively, locking the two fixing sleeves after the through-hole is formed. When the water-cooled pipe is inserted into the through-hole, tightening the fasteners 26 clamps the first fixing sleeve 24 and the second fixing sleeve 25, making the inner wall of the through-hole tightly fit against the surface of the water-cooled pipe, thereby effectively fixing the water-cooled pipe and preventing it from loosening or shifting during testing. This structure not only facilitates the quick installation and removal of the water-cooled pipe but also achieves reliable positioning and stable support.

[0034] This technical solution effectively solves the problems of insecure fixing, easy detachment, or displacement of water-cooling pipes in existing technologies by setting a limiting hole formed by the mating of the first fixing sleeve 24 and the second fixing sleeve 25, and using fasteners 26 to clamp and fix the water-cooling pipe. Existing water-cooling pipe support structures often suffer from the defect of easy loosening of the water-cooling pipe under long-term operation or external force, leading to unstable cooling effect and even affecting the accuracy of temperature testing. This solution uses the limiting hole to limit the water-cooling pipe around its perimeter, and the fasteners 26 reinforce the fixing sleeves, firmly fixing the water-cooling pipe to the designated position of the robotic arm 20. This ensures that the water-cooling pipe will not fall off or shift during operation, thereby guaranteeing the stability and accuracy of cooling and temperature testing. Therefore, this technical solution improves the fixing reliability and safety of the water-cooling pipe, solves the technical problem of easy detachment of the water-cooling pipe, and achieves the technical effect of efficient and stable limiting and fixing of the water-cooling pipe.

[0035] This embodiment provides a base 10 structure with a leakage collection function. As shown in the figure, the base 10 includes a housing 12 and a cover 14. The housing 12 is a hollow structure used to collect and contain liquid. The cover 14 covers the open end of the housing 12 and is fixed to the housing 12 by snaps, bolts, or other detachable connections, allowing for easy assembly and disassembly of the cover 14 and the housing 12. Multiple leakage holes 102 are provided on the surface of the cover 14. The size and distribution of the leakage holes 102 can be designed according to actual needs. When liquid leaks during equipment operation, the liquid can flow into the containment cavity 101 inside the housing 12 through the leakage holes 102 on the cover 14. The cover 14 and the housing 12 together form a complete containment cavity 101 for centralized collection and temporary storage of leaked liquid, preventing liquid overflow and pollution of the surrounding environment. When cleaning is required, simply remove the cover 14 from the housing 12 to drain and clean the liquid inside the housing 12; the operation is simple and quick.

[0036] This technical solution achieves effective collection and management of leaked liquid by incorporating a detachable cover 14 and a housing 12 within the base 10 structure, and by providing multiple leakage holes 102 on the cover 14. In existing technologies, the base 10 structure is often a one-piece design, lacking a reasonable liquid collection channel and convenient cleaning methods, leading to easy diffusion of leaked liquid, causing environmental pollution around the equipment, and making cleaning inconvenient. This technical solution, through the detachable connection between the cover 14 and the housing 12, facilitates maintenance and cleaning; the leakage holes 102 ensure that liquid can flow into the receiving cavity 101 of the housing 12 in a timely manner, preventing liquid accumulation or overflow on the surface of the cover 14, effectively collecting leaked liquid. This not only improves the safety and cleanliness of equipment use but also significantly reduces maintenance difficulty. In summary, this technical solution solves the technical problems of difficult liquid collection and inconvenient cleaning in existing base 10 structures, achieving the technical effect of centralized collection and easy cleaning of leaked liquid.

[0037] Please see Figures 1 to 4 As shown, Figure 4 This is a schematic diagram of the structure of the box 12 provided in this embodiment of the utility model.

[0038] This embodiment provides an improved base 10 structure, which includes a housing 12 and a cover 14. The bottom plate of the housing 12, opposite the cover 14, has a groove 124 at a localized location. Specifically, the groove 124 is a partially recessed structure, with its bottom lower than the rest of the bottom plate. For example, the bottom plate of the housing 12 may have a rectangular or circular groove 124, the depth of which is greater than the rest of the bottom plate, making the bottom of the groove 124 the lowest point of the bottom plate. When liquid leaks into the housing 12 through the drain hole 102 of the cover 14, the liquid preferentially flows into and accumulates in the groove 124, facilitating centralized collection and subsequent discharge or cleaning.

[0039] The cover 14 is detachably connected to the housing 12. When cleaning is required, the user can open the cover 14 to directly clean the liquid in the groove 124, reducing cleaning dead spots and improving maintenance efficiency. The specific shape and size of the groove 124 can be adjusted according to actual needs to accommodate liquid collection requirements of different volumes and flow rates.

[0040] This technical solution effectively solves the technical problems of liquid being difficult to concentrate in the cavity of the base 10, easily stagnating in corners or scattered throughout the base, leading to incomplete cleaning, pollution, and odor, by setting a groove 124 in a partial area of ​​the bottom plate opposite the housing 12 and the cover 14, with the bottom of the groove 124 being lower than the rest of the bottom plate. As the lowest point, the groove 124 guides leaked liquid to flow naturally and concentrate it within the groove 124, facilitating thorough cleaning in one go, reducing residual liquid, and improving the hygiene and ease of maintenance of the base 10.

[0041] Therefore, this technical solution achieves the technical effects of automatic liquid collection, convenient centralized collection and easy cleaning, and significantly improves the practicality and reliability of the base 10 structure in terms of liquid management and environmental maintenance.

[0042] This embodiment relates to a base 10 structure for facilitating liquid discharge. The base 10 includes a housing 12 and a cover 14. The housing 12 has an internal cavity 101 for collecting liquid. A groove 124 is provided in a localized area on the bottom plate opposite the cover 14, with the bottom of the groove 124 lower than the rest of the bottom plate, allowing liquid to accumulate there. To further facilitate liquid discharge, a liquid outlet 125 is provided in the housing 12 near the bottom of the groove 124. This outlet 125 communicates with the groove 124 and can be opened and closed using a threaded plug, a rotary valve, or other similar structure.

[0043] During actual use, the liquid generated during equipment operation flows into the receiving cavity 101 of the housing 12 through the drain hole 102 on the cover 14, and accumulates in the groove 124 on the bottom plate under gravity. When it is necessary to remove the liquid from the receiving cavity 101, the operator only needs to open the outlet 125 on the housing 12, and the liquid in the groove 124 can flow out smoothly, achieving complete drainage of the liquid in the receiving cavity 101 without tilting the housing 12 or performing tedious cleaning operations.

[0044] This technical solution solves the problem of incomplete drainage and inconvenient cleaning of the base 10's receiving cavity 101 in the prior art by setting a liquid outlet 125 on the housing 12 that communicates with the groove 124. Since the bottom of the groove 124 is located at the lowest point of the base plate and communicates with the liquid outlet 125, all liquid flowing into the receiving cavity 101 will eventually concentrate in the groove 124 under gravity. When drainage is required, simply opening the liquid outlet 125 allows for easy and thorough drainage of the liquid in the receiving cavity 101 without disassembling the base 10 or tilting the housing 12, greatly improving cleaning efficiency and convenience, and reducing the hygiene hazards caused by residual liquid.

[0045] Therefore, this technical solution enables rapid and complete drainage of liquid, significantly improving the ease of maintenance and safety of use of the base 10 structure, and achieving the technical effect of easy cleaning and prevention of liquid residue.

[0046] This embodiment relates to a structurally improved cover 14. The cover 14 is used in conjunction with a housing 12, primarily to prevent foreign objects from entering the housing 12 and to guide liquid into the housing 12 for collection. Specifically, the cover 14 comprises two parts: a main board 141 and a limiting plate 142.

[0047] The main board 141 is the main structural component covering the opening of the housing 12, and it has one or more drainage holes 102 to allow liquid to flow from the cover 14 into the housing 12. The number, distribution and size of the drainage holes 102 can be designed according to actual needs to ensure that liquid can flow smoothly through the main board 141 into the housing 12.

[0048] The limiting plate 142 has a ring-shaped structure and is arranged around the edge of the main board 141, that is, around the outer edge of the main board 141. The inner side of the limiting plate 142 is fixedly connected to the main board 141, and the outer side extends downward and contacts the outer peripheral surface of the housing 12. Through this structure, the limiting plate 142 can effectively limit the cover 14, prevent the cover 14 from moving laterally or misaligning during use, and improve the sealing and stability between the cover 14 and the housing 12.

[0049] In actual use, the cover 14 contacts and engages with the outer peripheral surface of the box 12 via the limiting plate 142, allowing the cover 14 to be accurately and stably installed on the opening of the box 12. The drain hole 102 on the main board 141 ensures that the liquid flows smoothly into the receiving cavity 101 inside the box 12, facilitating subsequent collection and cleaning.

[0050] This technical solution effectively solves the problems of misalignment and poor sealing of the existing cover 14 during installation by setting a main board 141 and a limiting plate 142 surrounding the edge of the main board 141, and ensuring that the limiting plate 142 contacts the outer peripheral surface of the housing 12. The limiting plate 142 serves to limit and guide, allowing the cover 14 to be accurately and firmly positioned at the opening of the housing 12, preventing the cover 14 from shifting or falling off due to external forces or vibrations. In addition, the contact between the limiting plate 142 and the outer peripheral surface of the housing 12 can also prevent external contaminants such as dust and debris from entering the housing 12, improving the overall sealing performance of the structure.

[0051] The drain hole 102 on the motherboard 141 ensures that the liquid can flow smoothly into the interior of the housing 12, which is conducive to the effective collection of the liquid and prevents spillage and contamination.

[0052] In summary, this technical solution, through the reasonable setting of the limiting plate 142 and the leakage hole 102, achieves reliable positioning of the cover 14 and smooth liquid introduction, improves the fit stability and sealing performance between the cover 14 and the box 12, thereby achieving the technical effects of preventing misalignment of the cover 14, facilitating liquid collection, and preventing contamination.

[0053] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0054] Furthermore, when an element is referred to as 'fixed to' or 'set on' another element, it may be directly attached to that element, or there may be other intervening elements between them. When an element is referred to as 'connected to' another element, it can be directly connected to the other element or indirectly connected to the other element through an intervening element.

[0055] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, the designation of features such as "first" and "second" can either explicitly express or imply the presence of at least one such feature.
