Description

Technical Field

[0001] This invention relates to the field of new energy vehicle battery technology, and more specifically, to a battery swapping compartment and cooling mechanism for automobiles. Background Technology

[0002] Among current energy replenishment technologies for new energy vehicles, battery swapping is gradually becoming the mainstream technology due to its fast replenishment speed and controllable battery life.

[0003] In existing technologies, most new energy vehicle battery swapping structures employ two main approaches. The first is chassis-integrated battery swapping, where the battery compartment is integrated into the vehicle chassis, requiring the swapping equipment to be lifted from the bottom for docking. This approach is susceptible to road conditions, and the battery compartment is a single, uninterrupted cavity, making a single battery pack failure a significant risk to the entire system. The second approach is lateral battery swapping. Some lateral swapping vehicles only use a single battery pack side-insertion design, failing to achieve modular replacement of multiple packs and lacking flexibility in range adjustment. Multi-pack swapping vehicles often employ a vertically stacked layout with vertically opening doors, requiring the swapping robot to perform a complex vertical lifting and horizontal movement motion. This results in a complex swapping process with high docking accuracy requirements, and the lack of physical gas chambers for double isolation between battery packs leads to weak thermal runaway protection. Furthermore, existing lateral swapping technologies generally suffer from a lack of auxiliary guidance for battery pack insertion and removal, resulting in high docking accuracy requirements, potential installation errors, and asynchronous door opening and swapping actions, impacting swapping efficiency.

[0004] Secondly, existing battery pack cooling mechanisms can be broadly categorized into two types. One type involves directly and relatively fixedly covering and installing the cooling plate onto the battery pack surface. While this method ensures a tight fit between the cooling plate and the battery pack, it necessitates connecting the cooling plate's piping every time the battery pack is installed in the vehicle, increasing the battery swapping steps and reducing swapping efficiency. Furthermore, the instantaneous impact force generated during piping connection can affect the lifespan of the entire heat exchange circuit. The other type involves directly fixing the cooling plate to the vehicle body, allowing it to naturally adhere to the battery pack after insertion. In this configuration, the presence of the cooling plate can interfere with the insertion and removal of the battery pack during swapping. Additionally, manufacturing and installation errors in the cooling plate, as well as differences in the battery pack's installation angle, can easily cause some areas of the battery pack to fail to maintain a tight fit with the cooling plate, potentially leading to partial heat loss and failure. Summary of the Invention

[0005] To overcome the shortcomings mentioned above, the present invention aims to provide a car battery swapping compartment and cooling mechanism that can solve the above problems.

[0006] The objective of this invention is achieved through the following technical solution: A car battery swapping compartment and cooling mechanism, comprising: The battery swapping compartment has two rows of battery compartments for installing battery packs, with multiple compartments in each row. Battery guide rails are provided on the front and rear sides of each battery compartment, supporting the bottom of the battery pack. The battery swapping compartment has side doors that can be opened and closed on the left and right sides, and door opening and closing mechanisms are provided on the front and rear sides of the battery swapping compartment for driving the side doors to open and close. The cooling mechanism includes a cooling plate, a main pipeline, and a connecting hose. The cooling plate is located at the bottom of the battery compartment and can be optionally attached to the bottom surface of the battery pack. The main pipeline is located above the main body of the battery swapping compartment. The connecting hose connects the cooling plate and the main pipeline. A cold plate lifting mechanism for driving the cooling plate to rise and fall is installed above the main body of the battery swapping compartment.

[0007] Furthermore, the cold plate lifting mechanism includes: The hook is pressed tight, with its lower end extending into the front or rear end of the battery compartment and connected to the front or rear end of the cooling plate, and its upper end moving through the battery swapping compartment body and extending above the battery swapping compartment body. A push beam is slidably disposed above the main body of the battery swapping compartment along the front-back direction. The push beam has multiple horizontal lifting guide holes, which are inclined. The lifting rod is horizontally fixed to the upper end of the clamping hook and moves through the lifting guide hole. A fixing frame is fixed to the top surface of the main body of the battery swapping compartment, and a limiting through hole is provided to restrict the vertical movement of the clamping hook, and the lifting rod passes through the limiting through hole; A cold plate lifting electric cylinder, used to drive the horizontal movement of the push beam, is installed above the main body of the battery swapping compartment.

[0008] Furthermore, the upper ends of the two clamping hooks between two adjacent cooling plates are connected to the same lifting rod.

[0009] Furthermore, the cooling plate has a first connecting lug fixed horizontally at both ends. The thickness of the first connecting lug is less than the thickness of the cooling plate, and the bottom surface of the first connecting lug is flush with the bottom surface of the cooling plate. The first connecting lug is located below the battery guide rail. The lower end of the clamping hook is provided with a second connecting lug horizontally. The second connecting lug is located below the first connecting lug and connected to the first connecting lug. When the first connecting lug rises to its top surface and abuts against the battery guide rail, the cooling plate is in close contact with the battery pack.

[0010] Furthermore, the fixing frame includes a first fixing frame and a second fixing frame; The first fixed frame is an n-shaped structure covering the outer side of the middle part of the push beam. The limiting through holes are provided at both ends of the first fixed frame. The cold plate lifting electric cylinder is fixed on the top surface of the first fixed frame. The top wall of the first fixed frame is provided with a push guide through hole. A push seat is fixed on the top surface of the push beam. The push seat passes through the push guide through hole and is fixedly connected to the output end of the cold plate lifting electric cylinder. Several second fixing frames are disposed on both sides of the first fixing frame, and the second fixing frames are arranged in an n-shaped structure and cover the outside of the push beam; Both the first and second fixed frames have horizontally opened horizontal guide through holes, and a guide shaft is slidably provided in the horizontal guide through holes. The guide shaft is located above the push beam and is fixedly connected to the push beam.

[0011] Furthermore, the door opening and closing mechanism includes: Door opening and closing push rods are installed at the front and rear ends of the battery swapping compartment body; The push arm has an inverted L-shaped structure. The end of the push arm's lateral portion, away from the longitudinal portion, is rotatably connected to the output end of the door opening / closing push rod. The middle portion of the push arm's longitudinal portion is rotatably connected to the main body of the battery swapping compartment. The linkage assembly consists of two sets of linkage assemblies located on the left and right sides of the push arm, with one end connected to the upper or lower end of the longitudinal part of the push arm and the other end connected to the side compartment door. The side door is provided with a side door pivot at the bottom of both the front and rear ends, and the side door is rotatably connected to the main body of the battery swapping compartment through the side door pivot.

[0012] Furthermore, the linkage assembly includes: One end of the push rod is rotatably connected to the upper or lower end of the longitudinal part of the push arm; A connecting rod is located at the end of the push rod away from the push arm, and its middle portion is rotatably connected to the push rod; the lower end of the connecting rod is rotatably connected to the main body of the battery swapping compartment. Push rod two, one end of which is rotatably connected to the upper end of the connecting rod, and the other end of which is rotatably connected to the side compartment door.

[0013] Furthermore, the battery swapping compartment body includes a main top plate, a main bottom plate, a main side plate, a cover plate, and a central partition plate. The main top plate and the main bottom plate are each provided with an opening corresponding to the battery compartment. The cover plate is adapted to the opening and is disposed on the top surface of the main top plate and the bottom surface of the main bottom plate. The main side plate is fixed to the front and rear sides of the main top plate and the main bottom plate. A central partition plate is provided between adjacent battery compartments. The central partition plate is fixedly connected to the main top plate and the main bottom plate. The battery guide rail is fixedly connected to the middle partition or the main body side plate. The battery guide rail has an L-shaped structure. The clamping hook is located on the side of the middle partition near the battery pack or on the inner side of the main body side plate. The clamping hook slides through the battery guide rail.

[0014] Furthermore, both the cold plate lifting mechanism and the compartment door opening and closing mechanism are connected to the vehicle's main control system. The main control system controls the linkage between these mechanisms; simultaneously, the compartment door opening and closing mechanism drives the side compartment door to open, while the cold plate lifting mechanism drives the cooling plate to descend and detach from the battery pack.

[0015] Furthermore, the main pipeline includes a main inlet pipe and a main outlet pipe, which are arranged vertically and in a U-shape, and are equipped with protective covers on the outside of the main inlet pipe and the main outlet pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The battery swapping compartment and cooling mechanism of the present invention have battery guide rails on the front and rear sides inside the battery compartment. The battery guide rails support the bottom of the battery pack, thereby guiding the insertion and removal of the battery pack during battery pack replacement, facilitating docking, and effectively avoiding installation deviations, preventing the phenomenon of the battery pack being higher on one side and lower on the other after installation.

[0017] The battery guide rail not only guides the insertion and removal of the battery pack and prevents installation deviations, but also limits the lifting stroke of the cooling plate. When the connecting lugs at both ends of the cooling plate rise to the point where the top surface of the connecting lugs abuts against the bottom surface of the battery guide rail, the cooling plate reaches its highest position. At this point, the cooling plate is in close contact with the battery pack, ensuring the cooling effect of the cooling plate. The battery guide rail prevents the cooling plate from rising further to avoid squeezing the battery pack, thus preventing damage to the battery pack or misalignment.

[0018] Both the cold plate lifting mechanism and the compartment door opening and closing mechanism are connected to the vehicle's main control system. The main control system controls the cold plate lifting mechanism and the compartment door opening and closing mechanism to work together. When the compartment door opening and closing mechanism drives the side compartment door to open, the cold plate lifting mechanism drives the cooling plate to descend and detach from the battery pack, so that the compartment door opening and the battery swapping action are synchronized, effectively improving the battery swapping efficiency.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0031] like Figures 1-4 As shown, the battery swapping compartment and cooling mechanism in this embodiment include a swapping compartment body, a compartment door opening and closing mechanism, a cooling mechanism, and a cold plate lifting mechanism.

[0032] The battery swapping compartment has two rows of battery compartments 1 for installing battery packs 9, with multiple compartments 1 in each row. Battery guide rails 2 are located on the front and rear sides of each battery compartment 1, supporting the bottom of the battery packs 9. Side doors 3 are located on the left and right sides of the battery swapping compartment, with each row of battery compartments sharing one side door 3. Door opening and closing mechanisms are located on the front and rear sides of the battery swapping compartment to drive the side doors 3.

[0033] In this embodiment, the battery swapping compartment includes a top plate 26, a bottom plate, side plates 28, a cover plate 29, and a partition plate 30. The top plate 26 and bottom plate have openings corresponding to the upper and lower ends of the battery compartment 1, with reinforcing ribs fixed within each opening. The cover plate 29 is fitted to the openings and bolted to the top surface of the top plate 26 and the bottom surface of the bottom plate. The side plates 28 are fixed to the front and rear sides of the top plate 26 and bottom plate. A partition plate 30 is provided between adjacent battery compartments 1, and the partition plate 30 is fixedly connected to the top plate 26 and bottom plate. Battery guide rails 2 are spaced apart from the bottom plate and fixedly connected to the partition plate 30 or the side plates 28. The battery guide rails 2 have an L-shaped structure.

[0034] By providing battery guide rails 2 on the front and rear sides inside the battery compartment 1, the battery guide rails 2 support the bottom of the battery pack 9, thereby guiding the insertion and removal of the battery pack 9 during replacement, facilitating docking, and effectively avoiding installation deviations, thus preventing the phenomenon that the installed battery pack 9 is higher on one side and lower on the other.

[0035] A high-voltage compartment is also provided between the two rows of battery compartments 1 on the left and right. A socket 27 for connecting to the battery pack 9 is installed on the side wall of the high-voltage compartment facing the battery compartment 1. The high-voltage compartment is equipped with a circuit that connects to the socket 27.

[0036] In this embodiment, combined with Figure 2 and Figure 3As shown, the cooling mechanism includes a cooling plate 4, a main pipeline, and a connecting hose 5. The cooling plate 4 is located at the bottom of the battery compartment 1. The cooling plate 4 is driven to rise and fall by a cooling plate lifting mechanism to fit or detach from the bottom surface of the battery pack 9. The main pipeline is located above the main body of the battery swapping compartment. The connecting hose 5 connects the cooling plate 4 and the main pipeline. The top plate 26 of the main body has a hose through hole for the connecting hose 5 to pass through. The end of the cooling plate 4 away from the side door 3 has a hose connector. The connecting hose 5 passes through the hose through hole and connects to the hose connector.

[0037] Specifically, the main pipeline includes a main inlet pipe 31 and a main outlet pipe 32. The main inlet pipe 31 and the main outlet pipe 32 are arranged vertically and in a U-shape. One end of the main inlet pipe 31 and the main outlet pipe 32 is closed, and the other end is connected to the pump body fixed to the vehicle body to form a loop. A protective cover 33 is provided on the outer side of the main inlet pipe 31 and the main outlet pipe 32.

[0038] In this embodiment, combined with Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 10 As shown, the cold plate lifting mechanism includes a clamping hook 6, a pushing beam 7, a lifting rod 8, a fixed frame, and a cold plate lifting electric cylinder 10.

[0039] The clamping hooks 6 are located on both sides of the middle partition 30 near the battery pack 9 and on the inner side of the main body side plate 28. The lower end of the clamping hooks 6 moves through the battery guide rail 2 and extends below the battery guide rail 2. The lower end of the clamping hooks 6 is connected to the cooling plate 4, and the upper end of the clamping hooks 6 moves through the main body top plate 26 and extends above the main body top plate 26.

[0040] Specifically, connecting ears 13 are horizontally fixed at both ends of the cooling plate 4. The thickness of connecting ears 13 is less than that of the cooling plate 4, and the bottom surface of connecting ears 13 is flush with the bottom surface of the cooling plate 4. Connecting ears 13 are located below the battery rail 2. Connecting ears 2 are horizontally provided at the lower end of the clamping hook 6. Connecting ears 2 are located below connecting ears 13 and connected to connecting ears 13. When connecting ears 13 rises until the top surface of connecting ears 13 abuts against the battery rail 2, the cooling plate 4 is in close contact with the bottom surface of the battery pack 9.

[0041] The pushing beam 7 is slidably mounted above the main body of the battery swapping compartment along the front-back direction. The pushing beam 7 has multiple lifting guide holes 11 horizontally, and the lifting guide holes 11 are inclined with one end higher than the other.

[0042] The lifting rod 8 is horizontally fixed to the upper end of the clamping hook 6 and moves through the lifting guide hole 11. As the pushing beam 7 moves horizontally, the lifting rod 8 rises and falls along the lifting guide hole 11. Specifically, the upper ends of the two clamping hooks 6 between two adjacent cooling plates 4, that is, the clamping hooks 6 on both sides of the same partition plate 30, are connected to the same lifting rod 8. The lifting guide holes 11 on the pushing beam 7 are set one-to-one with the lifting rods 8.

[0043] The mounting bracket is fixed to the top surface of the battery swapping compartment. The mounting bracket has a limiting through hole 12 to restrict the vertical movement of the clamping hook 6, and the lifting rod 8 slides through the limiting through hole 12. Specifically, the mounting bracket includes a first mounting bracket 14 and a second mounting bracket 15.

[0044] The first fixed frame 14 is an n-shaped structure covering the outer side of the middle part of the push beam 7. Both ends of the first fixed frame 14 are provided with limiting through holes 12. The cold plate lifting electric cylinder 10 is fixed on the top surface of the first fixed frame 14. The top wall of the first fixed frame 14 is provided with a push guide through hole 16. The top surface of the push beam 7 is fixed with a push seat 17. The push seat 17 passes through the push guide through hole 16 and is fixedly connected to the output end of the cold plate lifting electric cylinder 10.

[0045] Several second fixing frames 15 are arranged on the front and rear sides of the first fixing frame 14, and the second fixing frames 15 are arranged in an n-shaped structure on the outside of the push beam 7.

[0046] Preferably, both the first fixed frame 14 and the second fixed frame 15 are provided with horizontal guide through holes 18. A guide shaft 19 is slidably provided in the horizontal guide through holes 18. The guide shaft 19 is located above the push beam 7 and is fixedly connected to the push beam 7, thereby guiding the movement of the push beam 7 so that the push beam 7 moves only in the horizontal direction.

[0047] By setting up a cold plate lifting mechanism, the output end of the cold plate lifting electric cylinder 10 extends or shortens, driving the push seat 17 and the push beam 7 to move in the front and back direction. Then the lifting guide hole 11 moves in the front and back direction, thereby driving the lifting rod 8 and the pressing hook 6 to lift and lower, ultimately realizing the lifting and lowering of the cooling plate 4.

[0048] The battery guide rail 2 not only guides the insertion and removal of the battery pack 9 and prevents installation deviation of the battery pack 9, but also limits the lifting stroke of the cooling plate 4. When the connecting ears 13 at both ends of the cooling plate 4 rise to the point that the top surface of the connecting ears 13 abuts against the bottom surface of the battery guide rail 2, the cooling plate 4 rises to the highest position. At this time, the cooling plate 4 is in close contact with the battery pack 9 to ensure the cooling effect of the cooling plate 4. The battery guide rail 2 prevents the cooling plate 4 from rising further to avoid squeezing the battery pack 9, thus avoiding damage to the battery pack 9 or misalignment of the battery pack 9.

[0049] In this embodiment, as Figure 5As shown, the door opening and closing mechanism includes a door opening and closing push rod 20, a push arm 21, and a connecting rod 24 assembly. The door opening and closing push rod 20 is installed at the front and rear ends of the battery swapping compartment body. The push arm 21 has an inverted L-shaped structure. The end of the push arm 21 furthest from the longitudinal part is rotatably connected to the output end of the door opening and closing push rod 20, and the middle part of the longitudinal part of the push arm 21 is rotatably connected to the battery swapping compartment body. Two sets of connecting rod 24 assemblies are respectively located on the left and right sides of the push arm 21, with one end connected to the upper or lower end of the longitudinal part of the push arm 21, and the other end connected to the side door 3. Side door pivots 22 are provided at the bottom of the front and rear ends of the side door 3, and the side door 3 is rotatably connected to the battery swapping compartment body through the side door pivots 22.

[0050] Specifically, the connecting rod 24 assembly includes a first push rod 23, a connecting rod 24, and a second push rod 25. One end of the first push rod 23 is rotatably connected to the upper or lower end of the longitudinal portion of the push arm 21. The connecting rod 24 is located at the end of the first push rod 23 away from the push arm 21, and the middle part of the connecting rod 24 is rotatably connected to the end of the first push rod 23 away from the push arm 21. The lower end of the connecting rod 24 is rotatably connected to the main body of the battery swapping compartment. The compartment door opening / closing push rod 20 is an electric push rod or an electric cylinder.

[0051] By setting up a door opening and closing mechanism, the output end of the door opening and closing push rod 20 extends or shortens, driving the push arm 21 to rotate, thereby driving the push rod 23 to move, which in turn drives the connecting rod 24 to rotate along the lower end of the connecting rod 24, thereby causing the push rod 25 to push outward or pull back inward to realize the opening and closing of the side door 3.

[0052] Preferred, combined Figure 4 , Figure 6 and Figure 9 As shown, a dustproof strip 34 is fixed to the bottom of the side door 3 facing the battery compartment 1. A buffer pad mounting base 35 is installed on the side door 3 facing the battery compartment 1, and a buffer pad 36 is installed inside the buffer pad mounting base 35. The buffer pad mounting base 35 and the buffer pad 36 are correspondingly set to the battery compartment 1, and each battery compartment 1 has two buffer pad mounting bases 35 and buffer pads 36. Specifically, the buffer pad 36 is a polyurethane buffer pad. Sealing strips 37 are fixed to both ends of the main body top plate 26.

[0053] In this embodiment, both the cold plate lifting mechanism and the door opening and closing mechanism are connected to the vehicle's main control system. Specifically, the cold plate lifting cylinder 10 and the door opening and closing push rod 20 are connected to the vehicle's main control system. The main control system controls the cold plate lifting cylinder 10 and the door opening and closing push rod 20 to work together. Simultaneously, the door opening and closing push rod 20 drives the side door 3 to open, and the cold plate lifting cylinder 10 drives the cooling plate 4 to descend and detach from the battery pack 9. After the battery pack 9 is replaced, the main control system controls the cold plate lifting cylinder 10 and the door opening and closing push rod 20 to work together. Simultaneously, the door opening and closing push rod 20 drives the side door 3 to close, and the cold plate lifting cylinder 10 drives the cooling plate 4 to rise and contact the battery pack 9. In this embodiment, the vehicle battery swapping compartment and cooling mechanism enable simultaneous door opening and battery swapping actions, effectively improving swapping efficiency.

[0054] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
