Description

Technical Field

[0001] This utility model relates to the field of leakage detection technology, and in particular to a liquid-cooled charging base leakage detection device. Background Technology

[0002] With the rapid development of high-power electric equipment such as electric heavy-duty trucks, electric mining trucks, electric ships, and electric aircraft, higher requirements have been placed on the safety and reliability of their charging systems. To meet the heat dissipation demands of high-current charging, liquid cooling technology has been widely applied in charging base systems. Liquid-cooled charging bases are typically connected to liquid cooling pipes via a heat-conducting box, and the flow and sealing of the coolant are achieved through fluid adapters. The coolant is often a mixture of water and ethylene glycol; while its good thermal conductivity meets the heat dissipation requirements, its electrical conductivity also poses safety hazards.

[0003] In existing technologies, coolant leakage is prone to occur in fluid connection components due to factors such as aging of sealing rings, vibration and impact, or poor assembly. Once coolant leaks into electrical connection areas, it can easily cause short circuits, equipment failures, or even safety accidents. Therefore, existing liquid-cooled charging docks generally lack an effective means to monitor liquid cooling system leakage in real time, especially in space-constrained applications, where there is a lack of compact, responsive, and easily integrated leakage detection devices.

[0036] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below 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 skilled in the art without creative effort are within the scope of protection of the present utility model.

[0037] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] This utility model embodiment provides a liquid-cooled charging socket leakage detection device, such as... Figures 1 to 8 As shown, the liquid-cooled charging dock leakage detection device is installed inside the liquid-cooled charging dock. The liquid-cooled charging dock leakage detection device includes a storage box 10. The storage box 10 contains a detection component 20 and a first water-absorbing component 30 that are arranged in layers. The first water-absorbing component 30 is used to siphon the coolant leaking from inside the liquid-cooled charging dock.

[0040] The detection assembly 20 includes a detection plate 21, a first absorbent 30 overlapping the detection plate 21, the detection plate 21 is used to generate a leakage detection signal after contact with leaking coolant; two signal leads 22 are installed on the detection plate 21, the signal leads 22 are used to transmit the leakage detection signal of the detection plate 21.

[0041] It should be noted that the liquid-cooled charging dock leakage detection device provided by this utility model has a siphon effect on the coolant provided by the first water-absorbing component 30, which can quickly guide the leaking liquid to the detection area. The detection plate 21 can quickly respond and generate an electrical signal when there is a small amount of leakage, which can promptly feed the leakage information back to the upper control system (such as the vehicle or charging platform) for early warning and to prevent the accident from escalating. By integrating the detection plate 21 and the first water-absorbing component 30 into the storage box 10, the modular design facilitates installation and replacement. Therefore, it solves the technical problem of the lack of a leakage detection device for liquid-cooled charging docks in the prior art.

[0042] like Figures 1 to 6 As shown, the detection board 21 is a PCB printed circuit board. The detection board 21 includes a substrate 211. A first detection layer 212 and a second detection layer 213 are provided on the substrate 211. The first detection layer 212 and the second detection layer 213 are connected by the coolant leaking from the liquid-cooled charging base and generate a leakage detection signal.

[0043] The first detection layer 212 is electrically connected to one of the signal leads 22, and the second detection layer 213 is electrically connected to the other signal lead 22. In this embodiment, once coolant leaks from the fluid transfer member, it is siphoned by the first absorbent member 30 and conducted to the detection board 21. The coolant, as a conductive medium, bridges the path between the first detection layer 212 and the second detection layer 213, forming a closed circuit. Then, an electrical conduction signal is generated on the PCB printed circuit board and transmitted to the upper system (such as an on-board or charging platform) via the signal lead 22 to realize the leakage alarm or power-off operation.

[0044] It should be noted that the first detection layer 212 and the second detection layer 213 are connected by coolant, so detection can be triggered without a large amount of liquid accumulation; once the leaked liquid is absorbed and comes into contact with the circuit, a signal is generated on the circuit, with a short response time, enabling early alarm. The entire detection board 21 can be replaced independently or modularly packaged in the storage box 10; the signal lead-out line 22 facilitates interface matching with various controllers and adapts to various charging device structures.

[0045] like Figures 1 to 6 As shown, the first detection layer 212 includes a plurality of parallel first detection strips 2121, one end of each of the plurality of first detection strips 2121 is connected to a first connecting strip 2122, and the first connecting strip 2122 is electrically connected to one of the signal lead-out lines 22.

[0046] The second detection layer 213 includes a plurality of parallel second detection strips 2131, one end of each of the plurality of second detection strips 2131 being connected to a second connecting strip 2132, and the second connecting strip 2132 being electrically connected to another signal lead 22.

[0047] The first detection strip 2121 and the second detection strip 2131 are alternately spaced apart, and the first detection strip 2121 and the first connecting strip 2122 are also spaced apart from the second detection strip 2131 and the second connecting strip 2132 to form a serpentine groove. Specifically, the first detection layer 212 and the second detection layer 213 can both be made of conductive materials such as copper foil.

[0048] It should be noted that the first detection strip 2121 and the second detection strip 2131 are arranged alternately and interspersed to form a serpentine groove structure. This serpentine groove structure makes it easier for leaking liquid from multiple directions to contact the first detection strip 2121 and the second detection strip 2131 within the shortest path. This geometric arrangement increases the contact opportunity between the detection area and the coolant, effectively expanding the sensing range and making it suitable for micro-leakage early warning. The first detection strip 2121 and the second detection strip 2131 are completely isolated under normal conditions and will not trigger signals falsely. Once leakage occurs, the coolant fills the serpentine groove, forming a reliable conductive path and improving signal consistency. Utilizing the physical presence of the coolant as a conductive medium, conduction will not occur in non-liquid or humid environments. The detection board 21 can be manufactured using conventional PCB processes without the need for additional special sensors or devices. The overall structure is clear, the wiring is regular, and it facilitates industrial production and consistent control of detection.

[0049] like Figures 1 to 3As shown, it also includes a second absorbent component 40 installed inside the storage box 10. The second absorbent component 40 is pressed onto the first absorbent component 30, and is used to siphon away coolant leaking from the liquid-cooled charging base. In this embodiment, the second absorbent component 40 and the first absorbent component 30 are tightly pressed together to form a continuous liquid absorption path. The second absorbent component 40 can be made of the same or higher performance liquid-absorbing material as the first absorbent component 30 (such as high-density rock wool, hydrophilic foam, etc.); both the first absorbent component 30 and the second absorbent component 40 can be custom-molded according to the shape of the storage box 10 for easy pressing and fixing.

[0050] It should be noted that the second absorber 40, as the "first layer of liquid absorber", can immediately absorb leaked coolant;

[0051] Because the second absorbent element 40 is pressed against the first absorbent element 30, the liquid can be quickly transferred downwards through capillary action and rapidly introduced into the detection area; compared to a structure with only one layer of absorbent material, the overall response time is significantly shortened. The addition of the second absorbent element 40 increases the liquid absorption area and the three-dimensional absorption path, enabling the detection of coolant leaks from more directions, making it particularly suitable for actual installation environments with unpredictable liquid diffusion directions and complex interfaces. The second absorbent element 40 preferentially absorbs leaking liquid from above, preventing liquid from directly dripping or splashing onto the detection board 21; this delays the long-term exposure of the detection board 21 to a wet state, which helps improve circuit lifespan and reduce the probability of false triggering.

[0052] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the storage box 10 includes a first storage shell 11, a folding connecting rib 12, and a second storage shell 13 connected in sequence. The detection plate 21 is installed inside the first storage shell 11, and the second storage shell 13 is pressed against the second water-absorbing component 40. The first storage shell 11, the folding connecting rib 12, and the second storage shell 13 are integrally formed structures.

[0053] The first storage shell 11 and the second storage shell 13 are detachably connected. The first storage shell 11 has an integrally formed storage perimeter 111, which surrounds any leakage liquid stored inside the first storage shell 11. In this embodiment, the folding connecting rib 12, as a key component connecting the first storage shell 11 and the second storage shell 13, not only provides structural support but also ensures stability during shell disassembly.

[0054] It should be noted that the inclusion of the surrounding edge 111 ensures that leaked liquid does not spread inside or outside the storage box 10, enhancing the leak-proof performance of the detection device and allowing the coolant to be effectively guided within the storage box 10, reducing the safety hazards caused by leakage. The first absorbent component 30 and the second absorbent component 40 ensure the maximum absorption efficiency of the absorbent material, effectively guiding the coolant to the detection plate 21. The layered structure facilitates liquid distribution, allowing the liquid to quickly contact the PCB board, rapidly triggering the detection signal and improving the system's response speed. The first storage shell 11 and the second storage shell 13 are connected by the folding rib 12 and are detachable. This modular design makes the installation and replacement of the entire device more flexible and convenient.

[0055] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the first storage shell 11 and the second storage shell 13 are snapped together. The first storage shell 11 is provided with a first bolt hole 112, and the second storage shell 13 is provided with a second bolt hole 131 corresponding to the first bolt hole 112.

[0056] It should be noted that the first storage shell 11 and the second storage shell 13 are connected to each other by a snap-fit ​​mechanism, which allows for easy disassembly, assembly, and maintenance of the first and second storage shells 11 and 13. The first bolt hole 112 and the second bolt hole 131 facilitate the fixing of the storage box 10 with bolts. The storage rim 111 enhances the sealing of the storage box 10 and improves the efficiency of liquid collection.

[0057] like Figures 1 to 8 As shown, the first housing 11 is provided with a first clearance hole 113 and a second clearance hole 114. The first clearance hole 113 is used to avoid the wiring pins of the detection board 21, and the second clearance hole 114 is used to avoid the two signal lead wires 22.

[0058] It should be noted that the first clearance hole 113 ensures that the pins of the detection board 21 can pass smoothly through the first housing 11 without physical obstruction, thus preventing damage or poor contact of the pins. Furthermore, the second clearance hole 114 effectively ensures the smooth passage of the signal lead 22, preventing signal transmission instability or distortion caused by squeezing or interference of the signal lead. The reserved first clearance hole 113 and second clearance hole 114 make the installation of the pins and signal lead 22 more convenient, avoiding interference with other components during assembly and improving overall assembly efficiency. It also reduces the number of locations requiring manual adjustment or correction during assembly, improving production efficiency and consistency. The first clearance hole 113 and second clearance hole 114 prevent signal lines and pins from physical contact with other components, reducing signal errors or interference caused by friction or squeezing; this ensures signal integrity and accuracy, thereby improving the precision of the leak detection system.

[0059] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the first storage shell 11 is provided with a pre-installation hole 115, and the second storage shell 13 is provided with a pre-installation snap 14 corresponding to the pre-installation hole 115. The pre-installation snap 14 passes through the pre-installation hole 115 and engages with the first storage shell 11.

[0060] It should be noted that, through the use of pre-installed holes 115 and pre-installed spring clips 14, the pre-installation of the first storage shell 11 and the second storage shell 13 can be quickly completed without additional tools during the assembly process, improving production efficiency. The snap-fit ​​design avoids the use of traditional bolts or complex fasteners, simplifying the pre-assembly process of the storage box 10. The elasticity of the pre-installed spring clips 14 ensures that the first storage shell 11 and the second storage shell 13 are firmly snapped together, preventing the connection from loosening due to vibration or external force during equipment operation.

[0061] like Figure 7 and Figure 8 As shown, the pre-loaded clip 14 includes two clip bodies 141 arranged opposite to each other. Each clip body 141 is provided with a snap-fit ​​part 142. The clip body 141 is provided with a first guide slope 1411, and the snap-fit ​​part 142 is provided with a second guide slope 1421.

[0062] It should be noted that the guide slope design allows the pre-installed spring clip 14 to be smoothly inserted and accurately aligned with the predetermined position, avoiding errors that may be caused by manual adjustment and improving assembly efficiency. This structural design allows assemblers to quickly complete the fastening work without the aid of external tools, reducing installation time. The locking part 142 acts as a locking mechanism, ensuring a stable connection between the pre-installed spring clip 14 and the first receiving shell 11. It remains secure under vibration or external force, preventing loosening or malfunction; this increases the overall device's shock resistance and durability, improving the product's performance in high-vibration environments.

[0063] Working Principle: This utility model provides a liquid-cooled charging dock leakage detection device. Because the first absorbent component 30 has a siphon effect on the coolant, it can quickly guide the leaking liquid to the detection area. The detection plate 21 can quickly respond and generate an electrical signal in the event of a minor leak, allowing timely feedback of the leakage information to the upper-level control system (such as the vehicle or charging platform) for early warning and to prevent the accident from escalating. By integrating the detection plate 21 and the first absorbent component 30 into the storage box 10, the modular design facilitates installation and replacement. Therefore, it solves the technical problem of the lack of a leakage detection device in existing liquid-cooled charging docks.

[0064] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
