Description

Technical Field

[0002] This invention relates to the field of battery swapping cabinet technology for electric two-wheeled vehicles, specifically to a battery swapping cabinet for electric two-wheeled vehicles that can dissipate heat from the internal charger. Background Technology

[0004] The electric two-wheeler battery swapping station is an intelligent self-service battery swapping terminal based on Internet of Things (IoT) technology. It consists of an independent battery compartment, an intelligent control system, a communication module, and multiple safety protection devices. It supports 24-hour unattended operation. Users can complete the entire self-service operation of returning a depleted battery and picking up a fully charged battery by scanning a code with their mobile phones. The whole process takes only tens of seconds, realizing "swap and go". It effectively solves the problems of slow charging, range anxiety, and safety hazards of privately installed charging wires for electric two-wheelers. The equipment is equipped with safety functions such as overcharge protection, temperature monitoring, fire extinguishing, and anti-theft lock. It can be flexibly deployed in communities, business districts, logistics outlets, food delivery stations, and other scenarios. It is suitable for personal commuting and also meets the high-efficiency range needs of the food delivery and express delivery industries, helping to realize the green and convenient travel mode of vehicle-battery separation.

[0005] Chinese patent CN221900073U discloses an electric vehicle battery swapping cabinet with heat dissipation function, including a battery swapping cabinet body and a support base. The battery swapping cabinet body is bolted to the top of the support base. A partition is bolted inside the battery swapping cabinet body, and several support holes are bolted to both sides of the partition. This solves the problem that existing battery swapping cabinets for electric vehicles mainly use natural cooling for heat dissipation. Natural cooling is the most common heat dissipation method used in fully sealed battery swapping cabinets. The main principle of this heat dissipation method is to dissipate heat into the air through natural convection by means of the cabinet's own heat dissipation design. However, although this heat dissipation method has the advantage of reducing energy consumption, it also has the problem of poor heat dissipation effect. It cannot quickly dissipate the heat inside the electric vehicle battery swapping cabinet, which easily causes heat to accumulate inside, affecting the operation of the electric vehicle battery swapping cabinet.

[0006] The technical solution uses air cooling to dissipate heat from the charger. Although the structure is simple and easy to implement, it still has obvious shortcomings in actual use: external dust and debris easily adhere to and accumulate at the heat dissipation filter and heat dissipation vents, which can easily cause ventilation blockage after long-term use. On the other hand, in the hot summer environment, the heat dissipation efficiency of air cooling alone is limited and it is difficult to meet the heat dissipation requirements of the charger when it is working continuously at high power, which can easily lead to the charger overheating. While some existing solutions that use liquid cooling are better than air cooling in terms of heat dissipation efficiency, they still have defects: during long-term circulation, the coolant is prone to producing scale, colloids and various sediments. These impurities easily adhere to and accumulate on the inner walls of the cooling pipes and channels, resulting in a reduction in the flow cross-section of the pipes and a decrease in heat exchange efficiency, which in turn leads to a deterioration in the overall cooling effect and affects the stable operation of the charger and battery swapping cabinet.

[0014] This invention provides a battery swapping cabinet for electric two-wheeled vehicles that allows for heat dissipation of the internal charger. It offers the following advantages:

[0015] 1. This electric two-wheeler battery swapping cabinet, which can dissipate heat from the internal charger, features a water supply pipe. When the coolant flows through the water supply pipe, the water flow impacts and drives the spiral blades installed in the baffle to rotate synchronously. The rotating spiral blades create turbulent waves in the coolant inside the pipe, carrying tiny air bubbles mixed in with the coolant to the surface and dispersing the gas film attached to the inner wall of the flow channel, thus eliminating the risk of air blockage. On the other hand, it disperses agglomerated impurities in the coolant, preventing large particles from entering the downstream liquid cooling pipes and causing blockage. The spiral blades adopt a passive design driven by water flow to complete the exhaust and degassing, solving the problem of heat dissipation failure caused by air blockage due to air bubble accumulation in the liquid cooling system.

[0016] 2. This electric two-wheeler battery swapping cabinet, which can dissipate heat from the internal charger, features synchronous contact self-cleaning to solve filter plate clogging. Filtration and cleaning are carried out simultaneously, scraping away flocculent impurities and sticky sludge from the surface of the filter plate in real time. This prevents the filter plate from being easily clogged by soft impurities and causing flow attenuation, and achieves directional and sealed collection of impurities. The impurities can be centrally discharged and cleaned through the bottom drain valve.

[0017] 3. This electric two-wheeled vehicle battery swapping cabinet, which can dissipate heat from the internal charger, simultaneously performs real-time self-cleaning of the filter plates while the filtration process is underway. It is suitable for long-term unattended operation of outdoor battery swapping cabinets. The scraper rotates synchronously to sweep and remove flocculent impurities, colloids, and other interceptions attached to the surface of the filter plates in real time, avoiding coolant flow reduction caused by filter plate blockage. It can automatically adjust the bonding pressure according to the accumulation of impurities on the surface of the filter plates and the contact resistance. It automatically retracts when encountering hard impurities to avoid excessive squeezing pressure that could damage the filter plate screen or cause excessive wear of the scraper.

[0018] 4. This electric two-wheeler battery swapping cabinet can dissipate heat from the internal charger. It achieves simultaneous air cooling and self-cleaning. While forcibly cooling the heat dissipation fins and improving the efficiency of liquid cooling, it prevents the heat dissipation vents from being blocked, thus preventing the charger and battery from overheating due to the inability of hot air to escape from the cabinet. The combination of dry sweeping and spraying effectively removes stubborn dirt. While mechanically cleaning, cleaning liquid is sprayed at the same time, which can soften and decompose oil stains, solve stubborn attached impurities that cannot be removed by a simple brush, and improve cleaning ability.

[0019] 5. This electric two-wheeled vehicle battery swapping cabinet, which can dissipate heat from the internal charger, features simultaneous spraying and sweeping, significantly upgrading its cleaning capabilities and thoroughly solving stubborn blockages. The cleaning fluid spraying and the sweeping frame cleaning are completely synchronized. First, the cleaning fluid softens and decomposes the oil and sticky dust on the surface of the heat dissipation vents. Then, the sweeping frame evenly applies the cleaning fluid and completes mechanical scraping, solving stubborn adhering impurities that traditional dry sweeping cannot remove, avoiding blockage of the heat dissipation vents, and ensuring that the heat dissipation channels inside the cabinet remain unobstructed for a long time.

[0020] 6. This electric two-wheeled vehicle battery swapping cabinet, which can dissipate heat from the internal charger, has symmetrically arranged squeezing pipes at both ends of the fixed shaft, which can cover the full width of the cabinet door heat dissipation vent. The spraying range is perfectly matched with the cleaning stroke of the cleaning rack, so as to achieve no dead corners in the heat dissipation vent spraying and cleaning, and avoid local blockage and uneven heat dissipation caused by inadequate local cleaning.

[0035] Please see Figures 1-3 The present invention provides a battery swapping cabinet for electric two-wheeled vehicles that can dissipate heat from the internal charger, including a cabinet body 1, brackets 2 fixedly connected to both sides of the bottom of the cabinet body 1, charging compartments 3 evenly arranged on the front of the cabinet body 1, a cabinet door 5 installed on the back of the cabinet body 1, a heat dissipation component 6 fixedly connected to the inner side of the cabinet body 1, and a liquid cooling component 4 fixedly connected to the side of the cabinet body 1.

[0036] When charging starts, the liquid-cooled component 4 contacts the heat-generating surfaces such as the charger power module and heat dissipation substrate, quickly absorbing the heat generated during the charging process, and the temperature of the coolant rises accordingly.

[0037] At the same time, the heat dissipation component 6 starts working to cool the liquid cooling component 4 by air cooling, so as to dissipate heat outward;

[0038] Example 1, please refer to Figure 4 The present invention also includes a liquid cooling component 4. A second water pump 410 is fixedly connected to the water inlet end of the liquid cooling pipe 42. When the second water pump 410 is turned on, the output end of the second water pump 410 drives the coolant in the storage tank 43 into the supply water pipe 49, and continuously delivers the coolant to the liquid cooling pipe 42.

[0039] The other end of the water pipe 49 is fixedly connected to a baffle 47. The side of the baffle 47 is fixedly connected to the inside of the liquid storage tank 43. The side of the liquid storage tank 43 near the baffle 47 is rotatably connected to a spiral blade 48. When the coolant flows through the supply water pipe 49, the water flow impact drives the spiral blade 48 installed in the baffle 47 to rotate synchronously. The rotating spiral blade 48 forms a turbulent wave on the coolant in the pipe, which carries the tiny air bubbles mixed in the coolant to the liquid surface and discharges them, and disperses the gas film attached to the inner wall of the flow channel, eliminating the risk of air blockage. On the other hand, it disperses the agglomerated impurities in the coolant, preventing large particles of impurities from entering the downstream liquid cooling pipe 42 and causing blockage.

[0040] The coolant enters the liquid cooling pipe 42 through the liquid supply pipe 49, and comes into full contact with the heating surface of the charger inside the cabinet to absorb the heat generated during the charging process and complete the cooling and heat dissipation of the charger.

[0041] A water pump 44 is fixedly connected to the outlet end of the liquid cooling pipe 42, and a connecting pipe 45 is fixedly connected to the input end of the water pump 44. A filter mechanism 46 is fixedly connected to the other end of the connecting pipe 45. When the water pump 44 is turned on, the output end of the water pump 44 delivers the heat-absorbing coolant from the liquid cooling pipe 42 through the connecting pipe 45 to the filter mechanism 46. The filter mechanism 46 filters and purifies the impurities in the coolant. The filtered clean coolant flows back to the storage tank 43, completing the closed-loop circulation and realizing the continuous reuse of the coolant.

[0042] A water inlet valve 411 is fixedly connected to the middle of the side of the liquid storage tank 43. The water inlet valve 411 is provided on the side wall of the liquid storage tank 43. Coolant can be added to the liquid storage tank 43 by opening the water inlet valve 411 to ensure continuous and reliable circulating heat dissipation.

[0043] Please see Figure 5 It also includes a filter mechanism 46. The top of the filter housing 461 is fixedly connected to the bottom of the connecting pipe 45. During the return circulation, the water pump 44 is turned on. The output end of the water pump 44 sends the coolant that has completed heat absorption in the liquid cooling pipe 42 through the connecting pipe 45 into the inner cavity of the filter housing 461.

[0044] The coolant continuously impacts the swirling guide vanes 463 set in the filter housing 461, driving the guide vanes 463 to rotate. The rotating guide vanes 463 cause the coolant to form a spiral vortex. Under the action of centrifugal force, the heavier impurities such as scale in the coolant are thrown towards the inner wall of the filter housing 461 and settle down along the wall to the slag collection area at the bottom of the filter housing 461.

[0045] A guide vane 463 is provided between two filter plates 462. A cleaning mechanism 464 is fixedly connected to both sides of the guide vane 463. At the same time, when the swirling guide vane 463 rotates, it drives the cleaning mechanism 464 provided on both sides. The cleaning mechanism 464 forms a contact scraping with the filter plates 462 on both sides of the filter housing 461, and brushes away the flocculent impurities and colloidal deposits attached to the surface of the filter plates 462 in real time, so as to avoid clogging of the pores of the filter plates 462.

[0046] Both sides of the filter housing 461 are fixedly connected to filter plates 462. After the coolant is pre-separated by cyclone, it flows out after being finely filtered by the filter plates 462 on both sides of the filter housing 461. The clean coolant flows back into the storage tank 43 to complete the return filtration cycle.

[0047] The bottom of the filter housing 461 is equipped with a drain valve 465. During operation and maintenance, it is only necessary to open the drain valve 465 periodically to discharge and clean the impurities collected in the slag collection area at the bottom of the filter housing 461, thus avoiding pipeline blockage caused by the accumulation of impurities.

[0048] Please see Figures 6-7 The cleaning mechanism 464, and the two connecting shafts 4641 are fixedly connected to both ends of the spiral blade 48. The end of the connecting shaft 4641 away from the spiral blade 48 is rotatably connected to the side of the filter plate 462. After the coolant enters the inner cavity of the filter housing 461, it continuously impacts the guide vane 463 in the inner cavity, driving the guide vane 463 to rotate between the two sets of filter plates 462 inside the filter housing 461 through the connecting shaft 4641 with its two ends coaxially arranged.

[0049] Connecting frames 4642 are fixedly connected to both sides of the connecting shaft 4641. Scraper 4646 is slidably connected to the inner side of the connecting frame 4642. When the connecting shaft 4641 rotates synchronously with the guide vane 463, the scraper 4646 is driven by the connecting frames 4642 fixed on both sides to synchronously contact and rotate to scrape and clean the liquid-facing surfaces of the two sets of filter plates 462, so as to avoid the filter plates 462 from being blocked by the accumulation of impurities in the process of intercepting and filtering impurities in the coolant.

[0050] Sliding shafts 4644 are evenly arranged on the side of the scraper 4646. The side of the sliding shaft 4644 is slidably connected to the inner side of the connecting frame 4642. One end of the sliding shaft 4644 is fixedly connected to the scraper 4646, and the other end of the sliding shaft 4644 is fixedly connected to a circular plate 4643. A first spring 4645 is sleeved on the sliding shaft 4644. One end of the first spring 4645 is fixedly connected to the circular plate 4643, and the other end of the first spring 4645 is fixedly connected to the inner side of the connecting frame 4642. During the cleaning process where the scraper 4646 contacts the filter plate 462, when the scraper 4646 comes into contact with and is squeezed by the hard impurities accumulated on the surface of the filter plate 462, the reverse squeezing force on the scraper 4646 is transmitted to the circular plate 4643 through the sliding shaft 4644, causing the circular plate 4643 to slide along the inner cavity of the connecting frame 4642, while compressing the first spring 4645 sleeved on the sliding shaft 4644, thus realizing the adaptive floating and yielding of the scraper 4646.

[0051] This avoids the problem of the screen of the filter plate 462 being damaged and the scraper 4646 being worn due to excessive contact and squeezing pressure when the scraper 4646 comes into contact with the filter plate 462 for cleaning. At the same time, it ensures that the scraper 4646 always stays in contact with the surface of the filter plate 462, thus stabilizing the cleaning effect.

[0052] Heat dissipation fins 41 are evenly distributed on the outer wall of the liquid cooling pipe 42 near the cabinet door 5, which can exchange heat and dissipate heat for the coolant flowing in the liquid cooling pipe 42, reduce the coolant temperature, and ensure the heat dissipation efficiency of the liquid cooling cycle.

[0053] Example 2, please refer to Figures 8-10 The present invention also includes a heat dissipation component 6. Fan blades 64 are evenly arranged on the side of the support frame 62. A drive component 63 is fixedly connected to the other side of the support frame 62. The output end of the drive component 63 is fixedly connected to one end of the fan blades 64. During the process of heat exchange and heat dissipation of the coolant in the liquid cooling pipe 42 by the heat dissipation fins 41, the drive component 63 on the bracket 2 is activated, and the output end of the drive component 63 drives the fan blades 64 on the support frame 62 to rotate.

[0054] The other end of the fan blade 64 is fixedly connected to a connecting rod 65. The end of the connecting rod 65 away from the fan blade 64 is rotatably connected to the side of the cabinet door 5. The fan blade 64 generates directional airflow to cool the heat dissipation fins 41, thereby improving the heat exchange efficiency. When the fan blade 64 rotates, it drives the contact shafts 67 on both sides to rotate synchronously through the connecting rod 65. The contact shafts 67 then drive the cleaning frame 610 to perform contact cleaning on the heat dissipation vents of the cabinet door 5, preventing the heat dissipation vents from being blocked by dust accumulation and ensuring that the heat inside the cabinet 1 can be smoothly discharged.

[0055] The contact shaft 67 is slidably connected to slide rods 69 on both sides near the fan blade 64. The other end of the slide rod 69 is fixedly connected to a cleaning frame 610. A second spring 611 is sleeved on the slide rod 69. During the cleaning process, the cleaning frame 610 can achieve adaptive extension and retraction adjustment on the contact shaft 67 with the help of the two slide rods 69 and the second spring 611 sleeved on the slide rod 69, so that the cleaning component is always in close contact with the heat dissipation port surface, ensuring the cleaning effect.

[0056] Both sides of the connecting rod 65 are fixedly connected to the squeezing mechanism 68. When the fan blade 64 drives the connecting rod 65 to rotate, the connecting rod 65 will also drive the squeezing mechanism 68 on both sides to periodically contact and squeeze the guide block 66 on the cabinet door 5. While cleaning the heat dissipation vent, it continuously sprays out cleaning liquid, which removes stains in sync with the cleaning action, further improving the cleaning effect.

[0057] Please see Figure 11 It also includes a squeezing mechanism 68, a fixed shaft 681, a connecting rod 65 whose side is rotatably connected to the inside of a guide block 66, a fixed shaft 681 whose side is fixedly connected to the inside of a connecting rod 65, and squeezing pipes 682 whose ends are fixedly connected. When the fan blade 64 rotates, it drives the fixed shaft 681 to rotate coaxially through the connecting rod 65. The squeezing pipes 682 at both ends of the fixed shaft 681 rotate synchronously with the fixed shaft 681, so that the guide shaft 685 on the squeezing pipe 682 forms a periodic squeezing contact with the guide block 66 preset on the cabinet door 5 during the rotation process.

[0058] The side of the squeezing tube 682 is provided with a groove 683, and the side of the piston rod 684 is fixedly connected with a guide shaft 685. The side of the guide shaft 685 is slidably connected to the inner side of the groove 683. When the guide shaft 685 is squeezed by the guide block 66, it slides linearly along the groove 683 on the squeezing tube 682, thereby driving the piston rod 684 to perform squeezing and feeding movements in the inner cavity of the squeezing tube 682, while stretching the third spring 687 sleeved on the piston rod 684.

[0059] Piston plates 686 are evenly arranged on the side of piston rod 684. The inner side of piston plate 686 is fixedly connected to the side of piston rod 684. The piston plates 686 evenly arranged on piston rod 684 move synchronously with piston rod 684, squeezing the cleaning liquid stored in squeezing pipe 682, so that the cleaning liquid is sprayed out in a direction through the liquid outlet valve 688 on the side of squeezing pipe 682 towards the heat dissipation vent of cabinet door 5.

[0060] The side of the squeezing tube 682 is evenly provided with a liquid outlet valve 688. The side of the liquid outlet valve 688 is fixedly connected to the inside of the squeezing tube 682. The spraying of cleaning liquid and the contact cleaning action of the cleaning frame 610 are completely synchronized. The cleaning frame 610 evenly applies the sprayed cleaning liquid to the surface of the heat dissipation vent of the cabinet door 5, and removes the stains attached to the heat dissipation vent in sync with the mechanical cleaning.

[0061] Through the guiding and pressing cooperation of guide block 66 and guide shaft 685, uniform intermittent spraying of heat dissipation vents of cabinet door 5 is finally achieved.

[0062] Specific workflow:

[0063] When charging starts, the liquid cooling component 4 operates synchronously. The second water pump 410 drives the coolant in the liquid storage tank 43 into the liquid supply pipe 49, which is then sent to the liquid cooling pipe 42 that is in contact with the heat-generating surfaces such as the charger power module and heat dissipation substrate. The coolant directly absorbs the charging heat to complete the cooling.

[0064] After absorbing heat, the coolant is driven by water pump 44 and sent to filter mechanism 46 through connecting pipe 45. After purification, it flows back to storage tank 43 to form a closed loop.

[0065] The coolant tank 43 is equipped with a water inlet valve 411 on its side wall, which can be replenished with coolant at any time to ensure stable system operation.

[0066] When the coolant flows through the supply water pipe 49, the water flow impact drives the built-in spiral blade 48 to rotate, which discharges the tiny air bubbles in the coolant and breaks up the air film on the inner wall of the flow channel through turbulence, eliminating the risk of air blockage. At the same time, it disperses agglomerated impurities and avoids large particles of impurities from clogging the downstream pipeline.

[0067] After the coolant enters the filter housing 461, it impacts the built-in swirling guide vanes 463 to rotate. On the one hand, it drives the coolant to form a spiral vortex, and on the other hand, it uses centrifugal force to throw heavy impurities such as scale and metal shavings to the inner wall of the housing, where they settle to the bottom slag collection area to complete the pre-separation.

[0068] On the other hand, the guide vane 463 synchronously drives the scrapers 4646 on both sides to synchronously rotate and scrape the two sets of filter plates 462 inside the housing. The scraper 4646 is equipped with an elastic floating structure, which can adaptively adjust the bonding pressure, thereby removing flocculent impurities and colloids on the filter plates 462 in real time, avoiding screen hole blockage, and preventing excessive squeezing pressure from damaging the components.

[0069] The clean coolant that has been pre-separated and finely filtered flows back to the storage tank 43. The bottom of the filter housing 461 is equipped with a drain valve 465, which can periodically discharge the collected impurities.

[0070] The outer wall of the liquid cooling pipe 42 is evenly covered with heat dissipation fins 41 to enhance heat exchange. The driving component 63 drives the fan blades 64 to rotate and force air cooling to the fins, thereby improving heat dissipation efficiency.

[0071] At the same time, the fan blade 64, through the linkage structure, synchronously drives the cleaning frame 610 to adaptively and close to the heat dissipation vent of the cabinet door 5 for cleaning, so as to avoid dust accumulation and blockage of the heat dissipation channel.

[0072] The mechanically linked squeezing mechanism 68 synchronizes with the cleaning action to achieve intermittent and uniform spraying of cleaning liquid. This, combined with the cleaning action, removes stubborn stains such as scale and oil from the heat dissipation vents. The entire process can be completed with a single drive source, enabling the linkage of multiple actions including air cooling, cleaning, and spraying.

[0073] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
