[0002] With the rapid development of the new energy industry, battery swapping cabinets, as an important infrastructure for battery charging and swapping, are being used more and more widely in outdoor scenarios. However, battery swapping cabinets often face challenges from complex environmental factors during use, especially the problem of water immersion.

[0003] A waterproof battery swapping cabinet with publication number CN110481382A is disclosed. The cabinet contains a battery compartment. Rainwater entering the battery compartment opening is discharged outside the cabinet through a drainage structure. The drainage structure includes a water collection tray, a horizontal flow channel, and a vertical flow channel. The water collection tray is installed below the battery compartment, and the horizontal flow channel is installed inside the cabinet. Rainwater entering the battery compartment opening is received by the water collection tray.

[0004] The waterproof battery swapping cabinet with publication number CN221340240U includes a shell, multiple battery compartments for housing batteries, and multiple liquid guiding components for guiding water entering the battery compartments. The multiple battery compartments are installed inside the shell, and the liquid guiding components are installed on the lower side of the battery compartments.

The first pulley is rotatably arranged on the bottom side of the outer shell, and the second pulley is rotatably arranged on the top side of the battery swapping cabinet. Two electric telescopic rods are arranged on the top side of the central cavity. The push rod ends of the two electric telescopic rods are arranged opposite each other and are respectively fixedly connected to clamps.

[0018] Furthermore, the battery insertion compartment includes a battery insertion cavity opened on the battery swapping cabinet. A connecting groove is opened in the battery swapping cabinet below the battery insertion cavity. The connecting groove and the battery insertion cavity are interconnected through several lower through grooves. A support bar is provided between two adjacent lower through grooves. The support bar is protruding on the bottom surface of the inner side of the battery insertion cavity. The connecting groove is interconnected with the central cavity through three or more connecting holes.

[0019] Furthermore, the water level detection component includes several water level detection chambers evenly distributed at the bottom of the battery swapping cabinet and centered on the central axis of the cabinet. The lower ends of the water level detection chambers are interconnected by an annular liquid passage. Each water level detection chamber has a lower connecting hole at its lower end for communication with the outside. A solenoid valve capable of controlling the opening and closing of the lower connecting hole is provided at the lower connecting hole. Each water level detection chamber has an upper connecting hole at its upper end for communication with the interior of the central cavity. A liquid level sensor for detecting the liquid level height inside one of the water level detection chambers is provided.

[0020] Furthermore, the liquid suction assembly includes a liquid pump mounted on the outer casing. The outlet of the liquid pump is connected to a drain pipe, and the inlet of the liquid pump is connected to one end of a suction pipe.

[0021] Furthermore, a cooling fan is installed at the bottom of the central cavity, a supporting partition is installed on the inner wall of the central cavity above the cooling fan, a foot post is installed along the edge of the bottom side of the battery swapping cabinet, and a solar cell is installed on the charging structure.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. The water level is monitored in real time and accurately by the water level detection component. When the water level reaches the set height, the lifting rope counterweight structure is automatically triggered, which pulls the waterproof cover structure to extend upward, so as to achieve a full-round wrapping and sealing of the battery swapping cabinet. This effectively prevents external water from entering the battery compartment and the cabinet interior, avoids damage to the equipment due to water immersion, and significantly improves the safety performance of the battery swapping cabinet in water-related situations.

[0025] 2. The waterproof cover structure adopts a wave-shaped telescopic cover, a sealing ring and a sealing groove, combined with the guide groove and slider design to ensure smooth telescopic process without deviation; at the same time, the locking and limiting device can further fix the sealing ring, enhance the sealing effect, and ensure the reliability and stability of the waterproof structure.

[0026] 3. The liquid suction component can automatically extract and discharge the water in the water level detection chamber through the digital display control panel when the water level detection is completed or when water accumulation occurs, preventing water accumulation from affecting the detection accuracy or damaging the cabinet, thus improving the waterproof protection system.

[0027] 4. The locking and limiting device supports manual intervention and adjustment, which facilitates the disassembly and maintenance of the waterproof cover structure; the digital display control panel integrates multiple control functions, is intuitive and convenient to operate, facilitates the daily management and maintenance of the equipment, and enhances the practicality of the battery swapping cabinet.

[0028] 5. The central cavity not only accommodates key components such as the lifting rope counterweight structure and liquid suction assembly, but also provides space for the coordinated operation of various components, while playing a role in connection and buffering during drainage and heat dissipation.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0044] See Figures 1-12 As shown, this invention provides a waterproof battery compartment assembly for a battery swapping cabinet, comprising a cylindrical battery swapping cabinet body 1 and a digital display control panel. Several sets of battery insertion slots 2 are evenly distributed along the vertical direction on the outer side of the battery swapping cabinet body 1, with each set containing eight or more slots evenly distributed around the central axis of the battery swapping cabinet body 1. A central cavity 102 is located at the central axis of the battery swapping cabinet body 1. A waterproof cover structure 3 capable of vertical extension is located on the lower outer side of the battery swapping cabinet body 1. A water level detection component 7 for detecting water level is located in the lower inner part of the battery swapping cabinet body 1. A lifting rope counterweight structure 4 for lifting the waterproof cover structure 3 to provide waterproof protection for the battery swapping cabinet body 1 is located within the central cavity 102. A liquid suction component 6 for extracting water from the central cavity 102 is also located within the central cavity 102. The central cavity 102 not only accommodates key components such as the lifting rope counterweight structure 4 and the liquid suction component 6, but also provides space for the coordinated operation of various components, while playing a role in connection and buffering during drainage and heat dissipation. When the water level detection component 7 detects that the water level has risen to a certain height, the waterproof cover structure 3 extends upwards under the traction of the lifting rope counterweight structure 4. After extending, the waterproof cover structure 3 can enclose the entire battery swapping cabinet 1, preventing external water from entering and protecting the batteries in the battery compartment 2 and the electrical components inside the battery swapping cabinet 1 from water immersion damage, thus playing a crucial role in waterproof protection.

[0045] The waterproof cover structure 3 includes a housing 301, which is located on the outside of the battery swapping cabinet 1. A storage chamber is formed between the inner wall of the housing 301 and the outer wall of the battery swapping cabinet 1. A telescopic cover 302 is installed in the storage chamber, which serves to accommodate and protect the telescopic cover 302 and defines its installation space. The telescopic cover 302 has a wavy outline, and an upper ring 303 is provided on the upper side of the telescopic cover 302 to strengthen the structural strength of the upper side of the telescopic cover 302. During the extension of the telescopic cover 302, as the part connected to the lifting rope counterweight structure 4, it is easy to be pulled upward. The upper outer side of the battery swapping cabinet 1 is provided with an upper edge plate 305. A sealing ring 304 is provided on the upper side of the upper edge plate 305. A sealing groove 306 is opened on the lower side of the upper edge plate 305 for embedding and sealing with the sealing ring 304. When the water level detection component 7 detects that the water level has reached a certain height, the lifting rope counterweight structure 4 pulls the telescopic cover 302 upward and achieves the embedding and sealing of the sealing ring 304 and the sealing groove 306. Through the above-mentioned specific structural design, the waterproof cover structure 3 can automatically activate the waterproof mechanism when the water level rises. Through the extension of the telescopic cover 302, and the sealing structure formed by the sealing ring 304 and the sealing groove 306, it provides effective sealing and waterproof protection for the battery swapping cabinet 1, ensuring the safe operation of the equipment inside the battery swapping cabinet 1 in water-related situations, avoiding equipment damage or malfunction due to water intrusion, and improving the safety and reliability of the battery swapping cabinet 1 in special environments such as dampness or floods.

[0046] The outer side of the battery swapping cabinet 1 is provided with two or more guide grooves 104 evenly distributed at equal angles around its central axis. The extension direction of the guide grooves 104 is consistent with the axial direction of the battery swapping cabinet 1. The inner side wall of the upper ring body 303 is provided with guide sliders 315 corresponding to the guide grooves 104. The guide grooves 104 provide sliding tracks for the guide sliders 315, restricting their movement direction and ensuring that the upper ring body 303 drives the telescopic cover 302 to extend or retract smoothly along the axial direction of the battery swapping cabinet 1, preventing deviation or jamming during the extension and retraction process, and ensuring the normal operation of the waterproof structure. The lifting rope counterweight structure 4 includes a lifting rope 403 set in each guide groove 104. The lifting rope 403 is a key component for transmitting power. After the water level rises and triggers the mechanism, the gravity of the counterweight 404 transmits the pulling force to the guide slider 315, thereby pulling the upper ring body 303 to extend the telescopic cover 302 upward, achieving waterproof sealing. One end of the lifting rope 403 is fixedly connected to the corresponding guide slider 315, and the other end of the lifting rope 403 extends into the central cavity 102 and is fixedly connected to a counterweight 404. The counterweight 404 uses its own weight to provide driving force for the extension of the telescopic cover 302.

[0047] Two parallel side plates 307 are provided on the side of the upper edge plate 305 near the sealing groove 306. A locking block 308 is provided between the two side plates 307 through a hinge shaft 309. One end of the locking block 308 is shaped like a triangular prism. A torsion spring is provided between the hinge shaft 309 and the side plate 307. The other end of the locking block 308 is connected to a handle 310. A push rod 311 that can push the handle 310 is threaded on the upper edge plate 305. The upper end of the push rod 311 extends out of the upper surface of the upper edge plate 305 and is connected to a knob 312. A notch 313 is opened on the upper edge of the inner side of the sealing ring 304. A locking groove 314 for engaging with the locking block 308 is opened on the inner side of the sealing ring 304. This technical solution uses a locking and limiting device composed of a side plate 307, a hinge shaft 309, a locking block 308, and a torsion spring. The push rod 311 and the knob 312 work together to achieve flexible control and stable positioning of the sealing ring 304. When the telescopic cover 302 extends and the sealing ring 304 is embedded in the sealing groove 306, the operator can rotate the knob 312 to push the push rod 311, causing the locking block 308 to rotate and embed into the locking groove 314 of the sealing ring 304. Under the action of the torsion spring, it remains locked, preventing the sealing ring 304 from loosening or shifting, ensuring a good seal. When it is necessary to disassemble or adjust the telescopic cover 302, rotating the knob 312 causes the push rod 311 to disengage the handle 310 and the locking block 308 from the locking groove 314, thus unlocking the sealing ring 304. The entire structure ensures the reliability of the waterproof and sealed battery swapping cabinet while providing convenient manual intervention and adjustment methods, enhancing the practicality and ease of maintenance of the waterproof structure.

[0048] A charging structure 5 is provided on the top side of the battery swapping cabinet 1. The charging structure 5 includes an outer shell 501, a charger 502 is installed inside the outer shell 501, and a fixing column 503 is provided inside the outer shell 501 for fixing and supporting the charger 502. A gap is formed between the battery swapping cabinet 1 and the outer shell 501. An upper edge plate 305 is provided on the lower edge of the outer shell 501. A first pulley 401 and a second pulley 402 are rotatably installed in the gap for changing the direction of the lifting rope 403. The first pulley 401 is rotatably installed on the bottom side of the outer shell 501, and the second pulley 402 is rotatably installed on the top side of the battery swapping cabinet 1. Two electric telescopic rods 405 are provided on the top side of the central cavity 102. The push rod heads of the two electric telescopic rods 405 are arranged opposite each other and are respectively fixedly connected to clamps 406. The output end of the digital display control panel is electrically connected to the input end of the electric telescopic rods 405. In practical applications, the outer casing 501, charger 502, and fixing column 503 in the charging structure 5 work together to stably and safely provide power to the battery swapping cabinet 1. The gap between the battery swapping cabinet 1 and the outer casing 501 is used to arrange the first pulley 401 and the second pulley 402. These two pulleys, together with the lifting rope 403, optimize the traction path of the telescopic cover 302, ensuring smooth operation of the telescopic cover 302 during extension and retraction. Under the control of the digital display control panel, the electric telescopic rod 405 and the clamping block 406 can clamp and release the counterweight block 404, similar to a control switch. The entire system achieves efficient charging while ensuring that the telescopic cover 302 can promptly and stably provide waterproof sealing when the water level of the battery swapping cabinet 1 changes, comprehensively protecting the normal operation of the battery swapping cabinet 1 and its internal equipment under various working conditions, improving the reliability and practicality of the equipment.

[0049] The battery insertion compartment 2 includes a battery insertion cavity 201 opened on the battery swapping cabinet 1. A connecting groove 202 is opened in the battery swapping cabinet 1 located below the battery insertion cavity 201. The connecting groove 202 and the battery insertion cavity 201 are connected to each other through several lower through grooves 203. A support bar 204 is provided between two adjacent lower through grooves 203. The support bar 204 is raised on the bottom surface of the inner side of the battery insertion cavity 201. The connecting groove 202 is connected to the central cavity 102 through three or more connecting holes 205.

[0050] The water level detection component 7 includes several water level detection chambers 701 evenly distributed around the central axis of the battery swapping cabinet 1, located at the lower part of the cabinet. These chambers are used to contain water and provide space for water level detection. Their even distribution allows for sensing water level changes around the cabinet 1 from multiple directions, improving the comprehensiveness and accuracy of the detection. The lower ends of the water level detection chambers 701 are interconnected via an annular liquid passage 702. Each water level detection chamber 701 has a lower connecting passage 705 at its lower end for communication with the outside, and a solenoid valve 706 at the lower connecting passage 705 to control its opening and closing. Each water level detection chamber 701 has an upper connecting passage 704 at its upper end for communication with the interior of the central cavity 102. One of the water level detection chambers 701 contains a water level sensor 703 for detecting the internal liquid level. The output of the liquid level sensor 703 is electrically connected to the input of the digital display control panel, and the output of the digital display control panel is electrically connected to the input of the solenoid valve 706. In practical applications, the water level detection component 7, through the coordinated operation of its various components, achieves real-time, accurate detection and intelligent control of the water level around the battery swapping cabinet 1. Multiple evenly distributed water level detection chambers 701, in conjunction with the annular liquid passage 702, comprehensively sense changes in the external water level and maintain a consistent water level. The liquid level sensor 703 monitors the liquid level height within the water level detection chamber 701 in real time and transmits the data to the digital display control panel. When the water level reaches a preset threshold, the digital display control panel, on the one hand, controls the solenoid valve 706 to close the lower connecting passage 705 to prevent more water from entering; on the other hand, it sends a signal to the lifting rope counterweight structure and other related systems, triggering the lifting rope 403 to pull the telescopic cover 302 upward, achieving a waterproof seal for the battery swapping cabinet 1. The entire system is highly automated and can respond to water level changes in a timely and accurate manner, providing reliable waterproof warnings and protection for the battery swapping cabinet 1 and its internal equipment, thereby improving the safety and stability of the equipment in humid or flooded environments.

[0051] The liquid suction assembly 6 includes a liquid pump 601 mounted on the outer casing 501. The outlet of the liquid pump 601 is connected to a drain pipe 602, and the inlet of the liquid pump 601 is connected to one end of a suction pipe 603. The other end of the suction pipe 603 passes sequentially through the central cavity 102 and the upper connecting channel 704, extending into the water level detection chamber 701. The output terminal of the digital display control panel is electrically connected to the input terminal of the liquid pump 601. Through the coordinated operation of the liquid pump 601, drain pipe 602, suction pipe 603, and digital display control panel, the liquid suction assembly 6 achieves proactive and automated extraction and discharge of water accumulated in the water level detection chamber 701. When the water level in the water level detection chamber 701 is detected, or when water needs to be drained due to various reasons such as seepage or damage, the digital display control panel sends a start signal to the liquid pump 601 according to a preset program or manual instruction. After the liquid pump 601 starts, it generates suction, which draws out the water in the water level detection chamber 701 through the suction pipe 603, and then discharges the water through the drain pipe 602.

[0052] A cooling fan 8 is installed at the bottom of the central cavity 102. A supporting partition 103 is installed on the inner wall of the central cavity 102 above the cooling fan 8. A foot post 101 is installed along the bottom edge of the battery swapping cabinet 1. A solar cell 9 is installed on the charging structure 5. The output terminal of the digital display control panel is electrically connected to the input terminal of the cooling fan 8.

[0053] Working principle and technical effects of the present invention:

[0054] The battery is inserted into the battery insertion cavity 201 on the battery swapping cabinet 1 and placed on the support bar 204 for stable support. When removing or placing the battery, the operation is performed directly in the battery insertion cavity 201. Water seeping into the battery insertion cavity 201, as well as heat or moisture generated by the battery, can enter the connecting groove 202 through the lower through groove 203, and then enter the central cavity 102 through the connecting hole 205. When water accumulates around the battery swapping cabinet 1, the water level rises. When the water level sensor 703 in the water level detection assembly 7 detects that the water level has reached the set height, the solenoid valve 706 disconnects the lower connecting hole 705, and the lifting rope counterweight structure 4 starts working. The electric telescopic rod 405 drives the clamp 406 to release its grip on the counterweight block 404. The counterweight block 404 falls due to gravity, pulling the lifting rope 403. The lifting rope 403, through the guide slider 315, drives the telescopic cover 302 to extend upward along the guide groove 104. When the telescopic cover 302 rises to a certain position, the sealing ring 304 is embedded in the sealing groove 306 of the upper edge plate 305 to achieve a waterproof seal. At this time, the locking block 308 is engaged in the locking groove 314 of the sealing ring 304 to enhance the sealing effect. When water seeps into the central cavity 102, the liquid pump 601 is activated. The liquid pump 601 extracts the water from the water level detection chamber 701 through the suction pipe 603, and the water is discharged from the battery swapping cabinet 1 through the drain pipe 602. At the same time, during daily use, the cooling fan 8 works, and together with the central cavity 102, the connecting groove 202, the lower through groove 203, and the connecting hole 205, it can dissipate heat from all the battery compartments 2, which can reduce the internal temperature of the equipment and ensure the normal operation of the equipment.

[0055] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
