Description

Technical Field

[0001] This invention belongs to the technical field of battery thermal management and battery swapping equipment, specifically relating to a liquid-cooled circulating cooling battery swapping cabinet for liquid-cooled batteries. Background Technology

[0002] The rapid development of industries such as shared electric bicycles and food delivery has created a huge demand for fast battery swapping services. Existing battery swapping cabinets are typically multi-compartment charging stations where users can place depleted batteries in empty compartments to charge and remove fully charged batteries for use. However, existing battery swapping cabinets have serious drawbacks, including poor thermal management efficiency: most lack a temperature control system or rely solely on ordinary fans for air cooling. Air cooling is inefficient, noisy, and unable to handle the large amounts of heat generated by high-rate fast charging. This leads to excessively high battery temperatures during charging, severely limiting charging speed, accelerating battery lifespan degradation, and creating a potential safety hazard of thermal runaway.

[0003] Patent CN219421218U discloses a circulating cooling battery swapping cabinet. The front surface of the cabinet body has a display screen above the battery compartment. Above the display screen, a cleaning mechanism is also located on the front surface of the cabinet body. The cleaning mechanism includes a mounting plate installed on the upper surface of the cabinet body, a connecting plate mounted on the lower surface of the mounting plate via screws, and a movable plate below the connecting plate. A circulating cooling mechanism is located on one side of the cabinet body, including a circulating cooling box installed on one side. This patent utilizes a circulating water pump to pump coolant through an outlet pipe into a second connecting pipe, which then flows into a cooling pipe. A conductive plate is installed on the outside of the cooling pipe via a conductive sleeve, thus transferring the coolant from the coolant to the interior of the battery compartment, thereby achieving the purpose of cooling the interior of the cabinet body.

[0004] However, when the above-mentioned device is in use, it is difficult to make the cooling medium plate come into contact with the battery surface during the cooling process of the battery swapping cabinet. This can easily cause the battery temperature to gradually rise during the swapping process and the cooling speed to be slow, which in turn affects the battery swapping and cooling efficiency of new energy batteries. Summary of the Invention

[0005] The purpose of this invention is to provide a liquid-cooled circulating cooling battery swapping cabinet to solve the problem of slow battery cooling speed during swapping.

[0006] To achieve the above objectives, the present invention provides a liquid-cooled circulating cooling battery swapping cabinet, comprising: a guide slide installed inside the cabinet; a battery swapping cavity slidably connected to the inner wall of the guide slide; an elastic telescopic rod fixedly connected to the inner wall of the cabinet; an electric telescopic rod fixedly connected to the left side of the battery swapping cavity; a heat dissipation mechanism for ventilation and heat dissipation provided on the inner wall of the battery swapping cavity; a protective mechanism for battery protection provided on the inner wall of the battery swapping cavity; a mounting block fixedly connected to the telescopic end of the electric telescopic rod; an arc-shaped sliding column slidably connected to the inner wall of the battery swapping cavity; a connecting rod rotatably connected to the circumferential surface of the arc-shaped sliding column; a liquid-cooling medium plate fixedly connected to the right side of the arc-shaped sliding column; and a liquid-cooling medium plate fixedly connected to the right side of the elastic telescopic rod. The device is equipped with a connecting plate, to the bottom of which is fixedly connected a second liquid-cooling medium plate. The inner wall of the second liquid-cooling medium plate has a circulating liquid tank. A guide ramp is fixedly connected to the top of the battery swapping chamber. Rollers are rotatably connected to the inner wall of the connecting plate. A circulating water pump is installed on the cabinet. A liquid-cooled battery is installed in the battery swapping chamber, which is equipped with a battery swapping output interface. The cooling medium inside the first liquid-cooling medium plate allows it to contact the battery for heat exchange. This cooling process prevents the battery from overheating due to prolonged swapping time, thus reducing swapping safety hazards and improving the battery swapping quality of the device.

[0007] In one possible implementation, the connecting rod is rotatably connected to the inner wall of the mounting block, the roller is located on the movement trajectory of the guide ramp, and the guide ramp is used to push the roller to move upward. A flexible water pipe is installed on the second liquid cooling medium plate, enabling the second liquid cooling medium plate to circulate and cool the surface of the new energy liquid-cooled battery. The cooling medium circulates in a closed loop within the tank, which can significantly increase the heat exchange area and thermal conductivity between the battery and the cooling medium. It can quickly and evenly remove the heat generated by battery charging, avoid local high temperature and excessive temperature rise, reduce the risk of thermal runaway, improve charging safety and battery life, and allow the battery swapping cabinet to maintain a stable and reliable temperature control effect under continuous fast charging conditions.

[0008] In one possible implementation, the flexible water pipe is connected to the circulating water pump, the liquid-cooled battery is in contact with the second liquid-cooling medium plate, and the second liquid-cooling medium plate is used to cool the liquid-cooled battery. The placement of the battery swapping chamber will synchronously drive the guide ramp to move synchronously. After the guide ramp moves a certain distance, the inclined surface of the guide ramp will contact the roller. At this time, the guide ramp will continue to move. At this time, the guide ramp can squeeze and push the roller to rise through its own inclined surface.

[0009] In one possible implementation, the heat dissipation mechanism includes a second elastic telescopic rod, which is fixedly connected to the bottom of the battery swapping chamber. A connecting protrusion is fixedly connected to the telescopic end of the second elastic telescopic rod, and a sealing plate is fixedly connected to the surface of the connecting protrusion. A dustproof plate is fixedly connected to the inner wall of the battery swapping chamber. The sealing plate can open the bottom ventilation opening of the battery swapping chamber, which can quickly exhaust the residual heat and hot air accumulated around the battery and liquid cooling plate outside the chamber, reduce the heat dissipation pressure of the liquid cooling circulation system, avoid the liquid cooling medium from operating at a continuous high temperature, and improve the overall cooling efficiency.

[0010] In one possible implementation, the heat dissipation mechanism further includes an L-rod fixedly connected to the rear of the liquid cooling medium plate two. A hollow arc plate is fixedly connected to the bottom of the L-rod. A supporting arc frame is fixedly connected to the inner wall of the battery swapping chamber. A circulating water pipe is fixedly connected to the inner wall of the hollow arc plate. A temperature sensor is fixedly connected to the inner wall of the supporting arc frame. A temperature monitor is fixedly connected to the bottom of the supporting arc frame. By discharging cooling medium into the inner wall of the hollow arc plate, the battery swapping harness can be cooled in a timely manner, which can indirectly ensure the safe use of the device for battery swapping, improve the swapping efficiency of the device, and avoid the battery swapping circuit failure caused by excessive temperature of the swapping harness.

[0011] In one possible implementation, the connecting protrusion is located on the movement trajectory of the arc-shaped sliding column, and the arc-shaped sliding column is used to push the connecting protrusion to move downward. The sealing plate is in contact with the placement of the power exchange cavity, and the sealing plate is used to seal the opening of the placement of the power exchange cavity. The temperature sensor and the temperature monitor are connected by a connecting harness. The movement of the liquid cooling medium plate II will drive the L rod to move synchronously. The movement of the L rod will drive the hollow arc plate to move. During the downward movement of the hollow arc plate, the hollow arc plate will synchronously drive the circulating water pipe to move.

[0012] In one possible implementation, the protective mechanism includes a mounting bracket fixedly connected to the left side of the L-bar. A heat exhaust fan is fixedly installed on the inner wall of the mounting bracket, and a filter plate is fixedly connected to the inner wall of the cabinet. The heat exhaust fan can exhaust the air in the battery swapping chamber to the outside through the opening of the filter plate, enabling air exchange and ensuring that the temperature in the battery swapping chamber is always within a suitable range for battery swapping. This can cooperate with the liquid circulation cooling module to further improve the effectiveness of the device.

[0013] In one possible implementation, the protective mechanism further includes a signal transmission harness, which is fixedly connected to the bottom of the heat exhaust fan. An insulating arc frame is fixedly connected to the front of the support arc frame, which ensures that the device can achieve a cooling effect in a timely manner when the battery needs to be cooled. At the same time, the fixed installation of the insulating arc frame can always provide a stable and flexible support effect for the power supply harness, preventing the harness from falling off.

[0014] In one possible implementation, the exhaust fan is located directly in front of the filter plate, and the exhaust fan is used to exchange the hot air inside the battery compartment with outside air. The signal transmission harness is connected to the temperature monitor. The movement of the L rod will synchronously drive the mounting bracket to move. During the movement of the mounting bracket, the movement of the mounting bracket will drive the exhaust fan to move. After moving a short distance, the exhaust fan...

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This liquid-cooled battery swapping cabinet utilizes the coordinated movement of its cabinet body, guide slides, swapping chamber, elastic telescopic rod 1, electric telescopic rod, mounting block, arc sliding column, connecting rod, liquid cooling medium plate 1, connecting plate, liquid cooling medium plate 2, circulating liquid tank, guide ramp, and rollers. This allows the liquid cooling medium plate 1 to come into contact with the battery for heat exchange. During the swapping process of new energy liquid-cooled batteries, the cabinet cools the battery, preventing overheating and reduced swapping efficiency due to long swapping times. The cooling medium circulates in a closed loop within the tank, significantly increasing the heat exchange area and thermal conductivity between the battery and the cooling medium. This rapidly and evenly removes the heat generated during battery charging, preventing localized high temperatures and rapid temperature rises, reducing the risk of thermal runaway, improving charging safety and battery lifespan, and ensuring stable and reliable temperature control even under continuous fast charging conditions.

[0016] 2. This liquid-cooled battery swapping cabinet, through the coordinated movement of the elastic telescopic rod, connecting protrusion, sealing plate, dustproof plate, L-rod, hollow arc plate, circulating water pipe, supporting arc frame, temperature sensor, and temperature monitor, can open the bottom ventilation opening of the swapping chamber. This allows the residual heat and hot air accumulated around the battery and liquid cooling plate to be quickly discharged outside the chamber, reducing the heat dissipation pressure of the liquid cooling circulation system, preventing the liquid cooling medium from operating at continuously high temperatures, improving the overall cooling efficiency, and timely cooling of the battery swapping cable harness. This indirectly ensures the safe use of the device for battery swapping, improves the swapping efficiency of the device, and prevents the swapping circuit from being interrupted due to excessive temperature of the swapping cable harness.

[0017] 3. This liquid-cooled battery-powered circulating cooling battery swapping cabinet, through the coordinated movement of the mounting frame, exhaust fan, filter plate, signal transmission harness, and insulating arc frame, enables the exhaust fan to expel air from the battery swapping chamber to the outside through the openings in the filter plate, facilitating air exchange and ensuring that the temperature inside the battery swapping chamber remains within a suitable range for battery swapping. This, combined with the liquid circulating cooling module, further enhances the device's effectiveness, ensuring timely cooling when battery cooling is required. Simultaneously, the fixed installation of the insulating arc frame provides stable and flexible support for the battery swapping harness, preventing it from detaching. Attached Figure Description

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figures 1-7 As shown, one embodiment of the present invention is: a liquid-cooled battery swapping cabinet with liquid-cooled circulating cooling, comprising: a guide slide 2 installed inside the cabinet body 1; a battery swapping cavity 3 slidably connected to the inner wall of the guide slide 2; an elastic telescopic rod 4 fixedly connected to the inner wall of the cabinet body 1; an electric telescopic rod 5 fixedly connected to the left side of the battery swapping cavity 3; a heat dissipation mechanism 6 for ventilation and heat dissipation provided on the inner wall of the battery swapping cavity 3; a protective mechanism 7 for battery protection provided on the inner wall of the battery swapping cavity 3; a mounting block 8 fixedly connected to the telescopic end of the electric telescopic rod 5; and an arc-shaped... The sliding column 9 is rotatably connected to the circumference of the arc sliding column 9 and the connecting rod 10. The right side of the arc sliding column 9 is fixedly connected to the liquid cooling medium plate 11. The telescopic end of the elastic telescopic rod 4 is fixedly connected to the connecting plate 12. The bottom of the connecting plate 12 is fixedly connected to the liquid cooling medium plate 23. The inner wall of the liquid cooling medium plate 213 is provided with a circulating liquid tank 14. The top of the battery swapping chamber 3 is fixedly connected to the guide inclined plate 15. The inner wall of the connecting plate 12 is rotatably connected to the roller 16. The cabinet 1 is equipped with a circulating water pump. The battery swapping chamber 3 is equipped with a liquid-cooled battery. The battery swapping chamber 3 is provided with a battery swapping output terminal interface. When the device needs to swap new energy liquid-cooled batteries, the operator moves the swapping chamber 3 to a suitable position, places the new energy liquid-cooled battery on the inner wall of the swapping chamber 3, and swaps the battery itself through the swapping cable harness. After preparation, the swapping chamber 3 will reset. After a period of swapping, the electric telescopic rod 5 will start, and the telescopic end of the electric telescopic rod 5 will drive the mounting block 8 to move. During the movement of the mounting block 8, the mounting block 8 will drive the connecting rod 10 to move. However, at this time, there is a large angle difference between the initial angle of the mounting block 8 and the connecting rod 10. At this time, the connecting rod 10 will adjust its angle synchronously during the movement. During the angle adjustment process, the connecting rod 10 will simultaneously drive the arc sliding column 9 to move. At this time, the arc sliding column 9 will slide on the inner wall of the battery swapping chamber 3. Simultaneously, the movement of the arc sliding column 9 will also drive the liquid cooling medium plate 11 to move. After moving a certain distance, the liquid cooling medium plate 11 will come into contact with both sides of the new energy battery. At this time, the cooling medium inside the liquid cooling medium plate 11 can make the liquid cooling medium plate 11 and the battery come into contact and exchange heat. This can cool the battery during the battery swapping process of the new energy liquid-cooled battery, avoid the new energy battery from being too hot due to the long swapping time, reduce the battery swapping efficiency, reduce the battery swapping safety hazards, and improve the battery swapping quality of the device. The connecting rod 10 is rotatably connected to the inner wall of the mounting block 8. The roller 16 is located on the movement trajectory of the guide inclined plate 15, and the guide inclined plate 15 is used to push the roller 16 to move and rise. A flexible water pipe is installed on the liquid cooling medium plate 13, and the flexible water pipe is connected to the circulating water pump. The liquid-cooled battery is in contact with the liquid cooling medium plate 13, and the liquid cooling medium plate 13 is used to cool the liquid-cooled battery. As the battery swapping chamber 3 moves outward, it simultaneously moves the guide ramp 15. After moving a certain distance, the ramp 15 contacts the roller 16. The guide ramp 15 continues to move, pressing and pushing the roller 16 upward. Before moving, the roller 16 first transmits the pressing force to the elastic telescopic rod 4, which compresses to ensure the roller 16 can rise. The movement of the roller 16 moves the connecting plate 12, which in turn moves the liquid cooling medium plate 13 upward. At this point, the battery can be placed inside the battery swapping chamber 3. Similarly, when placing a new energy battery inside the connecting plate... After completion, the battery swapping chamber 3 will reset, and similarly, the liquid cooling medium plate 13 will reset. At this time, the liquid cooling medium plate 13 will contact the top of the new energy battery undergoing battery swapping. At the same time, the circulating water pump will start, which can discharge the cooling liquid medium into the circulating liquid tank 14 through the flexible water pipe for circulation. During the circulation of the cooling liquid medium, the liquid cooling medium plate 13 can circulate and cool the surface of the new energy liquid-cooled battery. The cooling medium circulates in a closed loop in the tank, which can greatly increase the heat exchange area and heat conduction efficiency between the battery and the cooling medium. It can quickly and evenly remove the heat generated by battery charging, avoid local high temperature and excessive temperature rise, reduce the risk of thermal runaway, improve charging safety and battery life, and allow the battery swapping cabinet to maintain a stable and reliable temperature control effect under continuous fast charging conditions. Overall working principle: The cooling medium inside the liquid cooling medium plate 11 allows the liquid cooling medium plate 11 to come into contact with the battery for heat exchange. During the battery swapping process of the new energy liquid-cooled battery, it cools the battery, preventing the battery from overheating due to long swapping time. This improves the swapping quality of the new energy battery. The cooling medium circulates in a closed loop within the tank, which can significantly increase the heat exchange area and thermal conductivity between the battery and the cooling medium. It quickly and evenly removes the heat generated by battery charging, avoids local high temperature and excessive temperature rise, reduces the risk of thermal runaway, improves charging safety and battery life, and allows the battery swapping cabinet to maintain a stable and reliable temperature control effect under continuous fast charging conditions.

[0022] like Figures 1-7As shown, based on the above embodiments, in another embodiment of the present invention, the heat dissipation mechanism 6 includes a second elastic telescopic rod 601, the second elastic telescopic rod 601 is fixedly connected to the bottom of the battery swapping cavity 3, the telescopic end of the second elastic telescopic rod 601 is fixedly connected to a connecting protrusion 602, the surface of the connecting protrusion 602 is fixedly connected to a sealing plate 603, and the inner wall of the battery swapping cavity 3 is fixedly connected to a dustproof plate 604. During the use of the device, after the arc-shaped sliding column 9 moves a certain distance, the arc surface of the arc-shaped sliding column 9 will contact the arc surface of the connecting protrusion 602. At this time, the arc-shaped sliding column 9 will continue to move. The arc-shaped sliding column 9 can squeeze and push the connecting protrusion 602 downward through its own arc surface. During the downward movement of the connecting protrusion 602, the connecting protrusion 602 will simultaneously drive the sealing plate 603 to move downward. After the sealing plate 603 moves, it can open the bottom ventilation opening of the battery swapping chamber 3, which can quickly exhaust the residual heat and hot air accumulated around the battery and liquid cooling plate outside the chamber, reduce the heat dissipation pressure of the liquid cooling circulation system, avoid the liquid cooling medium from operating at a high temperature, and improve the overall cooling efficiency. The heat dissipation mechanism 6 also includes an L-rod 605, which is fixedly connected to the rear of the liquid cooling medium plate 13. A hollow arc plate 606 is fixedly connected to the bottom of the L-rod 605. A supporting arc frame 608 is fixedly connected to the inner wall of the power exchange cavity 3. A circulating water pipe 607 is fixedly connected to the inner wall of the hollow arc plate 606. A temperature sensor 609 is fixedly connected to the inner wall of the supporting arc frame 608. A temperature monitor 610 is fixedly connected to the bottom of the supporting arc frame 608. A connecting protrusion 602 is located on the movement trajectory of the arc sliding column 9, and the arc sliding column 9 is used to push the connecting protrusion 602 to move downward. A sealing plate 603 contacts the power exchange cavity 3, and the sealing plate 603 is used to seal the opening of the power exchange cavity 3. A connecting wire harness is connected to the temperature sensor 609 and the temperature monitor 610. During the downward reset process of the liquid cooling medium plate 13, its movement causes the L-rod 605 to move synchronously. The movement of the L-rod 605 then causes the hollow arc plate 606 to move. As the hollow arc plate 606 moves downward, it simultaneously drives the circulating water pipe 607 to move. After the new energy battery is placed in the battery swapping chamber 3, it will be swapped via the battery swapping cable harness. At this time, the battery swapping cable harness will connect to the battery swapping output interface on the battery swapping chamber 3. Simultaneously, the battery swapping cable harness will be located on the inner wall of the supporting arc frame 608, which provides support and protection for the battery swapping cable harness. When the wiring harness is in use, the wiring harness will generate heat. At this time, the temperature sensor 609 set on the inner wall of the support arc frame 608 can come into contact with the wiring harness and transmit the temperature index to the temperature monitor 610. The temperature monitor 610 can determine whether the wiring harness needs to be cooled based on the externally set index. When cooling is required, the cooling medium is discharged into the inner wall of the hollow arc plate 606 through the circulating water pipe 607 connected to the external pump body. This can cool the battery wiring harness in time, which can indirectly ensure the safe use of the device for battery swapping, improve the swapping efficiency of the device, and avoid the swapping circuit failure caused by the overheating of the wiring harness. The protective mechanism 7 includes a mounting bracket 701, which is fixedly connected to the left side of the L rod 605. A heat exhaust fan 702 is fixedly installed on the inner wall of the mounting bracket 701, and a filter plate 703 is fixedly connected to the inner wall of the cabinet 1. During use, the movement of L-bar 605 will synchronously drive the mounting bracket 701 to move. As the mounting bracket 701 moves, it will also drive the exhaust fan 702 to move. After moving a short distance, the exhaust fan 702 will be positioned directly in front of the filter plate 703 and can be activated. The exhaust fan 702 can exhaust the air in the battery swapping chamber 3 to the outside through the opening of the filter plate 703, thus enabling air exchange and ensuring that the temperature in the battery swapping chamber 3 is always within the range suitable for battery swapping. It can work in conjunction with the liquid circulation cooling module to further improve the performance of the device. The protective mechanism 7 also includes a signal transmission harness 704, which is fixedly connected to the bottom of the exhaust fan 702. An insulating arc frame 705 is fixedly connected to the front of the support arc frame 608. The exhaust fan 702 is located directly in front of the filter plate 703 and is used to exhaust and exchange the hot air inside the battery compartment 3 with outside air. The signal transmission harness 704 is connected to the temperature monitor 610. When the device is in use, after the temperature sensor 609 transmits the temperature value to the temperature monitor 610, the temperature monitor 610 can transmit the signal to the control terminal of the exhaust fan 702 through the signal transmission harness 704 and start the exhaust fan 702. This ensures that the device can achieve the cooling effect in a timely manner when the battery needs to be cooled. At the same time, the fixed installation of the insulating arc frame 705 can always provide a stable and flexible support for the replacement wire harness and prevent the wire harness from falling off. Overall working principle: It can quickly expel the residual heat and hot air accumulated around the battery and liquid cooling plate to the outside of the chamber, reduce the heat dissipation pressure of the liquid cooling circulation system, avoid the continuous high temperature operation of the liquid cooling medium, improve the overall cooling efficiency, and cool the battery swapping harness in a timely manner. This indirectly ensures the safe use of the device for battery swapping, improves the swapping efficiency of the device, and avoids the swapping circuit failure caused by the overheating of the swapping harness. The exhaust fan 702 can exhaust the air in the swapping chamber 3 to the outside through the opening of the filter plate 703, enabling air exchange and ensuring that the temperature in the swapping chamber 3 is always within the suitable range for swapping. It can cooperate with the liquid circulation cooling module to further improve the use effect of the device and ensure that the device can achieve the cooling effect in a timely manner when the battery needs to be cooled. At the same time, the fixed installation of the insulating arc frame 705 can always provide a stable and flexible support for the swapping harness, preventing the harness from falling off.
