Description

Technical Field

[0001] This invention relates to the field of vehicle battery swapping technology, and in particular to a battery swapping device. Background Technology

[0002] Battery swapping for electric vehicles involves replacing the battery pack to meet the power needs of the vehicle. A shuttle is used during this process. The shuttle carries the battery pack between the electric vehicle and the battery compartment, facilitating the installation and removal of the battery pack relative to the electric vehicle. Unlocking the battery pack from the bottom of the electric vehicle relies on an unlocking mechanism on the shuttle. This mechanism drives a push rod upwards to disengage the locking linkage of the battery pack's locking mechanism, thus unlocking the vehicle.

[0003] Because the unlocking mechanism needs to drive the top rod to rise and fall, and its height is relatively large, it can only be fixed on the base plate of the battery swapping platform of the shuttle. An additional horizontal moving mechanism is also required to drive the unlocking mechanism located on the base to align with the locking mechanism that fixes the battery pack, which makes the structure of the shuttle complex and the control process relatively complicated. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing shuttle car in terms of complex structure and cumbersome control process, and to provide a battery swapping device.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A battery swapping device includes a battery swapping platform. The battery swapping platform includes a base and an unlocking mechanism. The unlocking mechanism is used to unlock the locking mechanism of an electric vehicle. The battery swapping platform also includes a battery support plate and a displacement adjustment mechanism. The battery support plate is used to support a battery pack. The battery support plate is disposed above the base and connected to the base through the displacement adjustment mechanism. The displacement adjustment mechanism is used to drive the battery support plate to reciprocate along a first horizontal direction. The unlocking mechanism is disposed on the side of the battery support plate and connected to the battery support plate.

[0007] In this battery swapping device, the unlocking mechanism is positioned on the side of the battery carrier plate, utilizing the side space to accommodate it. This effectively solves the problem of the unlocking mechanism being too large and thus only able to be mounted on the upper surface of the base. Simultaneously, the battery carrier plate supports the battery pack and, driven by the displacement adjustment mechanism, adjusts its position relative to the locking mechanism of the electric vehicle. The unlocking mechanism, connected to the battery carrier plate, adjusts its position synchronously with the battery carrier plate to achieve alignment with the locking mechanism of the electric vehicle. Therefore, there is no need to separately set up a drive mechanism to adjust the horizontal position of the unlocking mechanism, effectively simplifying the structure of the battery swapping device and making the battery swapping control process relatively simple.

[0008] Preferably, the battery swapping platform further includes an adapter plate, which has a first mounting surface and a second mounting surface that are set at an angle to each other. The first mounting surface is connected to the upper surface of the battery carrier plate near the side, and the second mounting surface is connected to the side of the unlocking mechanism.

[0009] This structural design uses an adapter plate to connect the unlocking mechanism to the battery carrier plate. The first mounting surface of the adapter plate is connected to the upper surface of the battery carrier plate near the side, which facilitates the disassembly and maintenance of the adapter plate and the battery carrier plate.

[0010] Preferably, the adapter plate also has a reinforcing member, the two sides of which are respectively connected to the first mounting surface and the second mounting surface.

[0011] By adding reinforcement components, the first and second mounting surfaces of the adapter board are structurally strengthened to prevent deformation during continuous use.

[0012] Preferably, the battery swapping platform further includes a battery tray located above the battery support plate. The battery tray is used to directly support the battery pack. In the vertical direction, the battery tray is elastically connected to the battery support plate, and in the horizontal direction, the battery tray is positioned and connected to the battery support plate.

[0013] In the horizontal direction, the top rod of the unlocking mechanism does not interfere with the battery tray.

[0014] A battery tray is placed above the battery support plate, and the battery tray contacts the bottom surface of the battery pack to achieve direct support of the battery pack.

[0015] The battery tray and the battery support plate are elastically connected in the vertical direction to achieve cushioning and prevent the impact force of the battery pack being placed on the battery tray from being quickly transmitted to the battery support plate, which would cause damage to the components (such as the unlocking mechanism) set on the battery support plate.

[0016] Meanwhile, the battery tray and the battery support plate are positioned and connected in the horizontal direction so that the horizontal driving force of the displacement adjustment mechanism on the battery support plate can be directly transmitted to the battery tray to achieve the purpose of horizontal position adjustment.

[0017] Preferably, the unlocking mechanism is a two-stage unlocking mechanism, and the battery swapping platform also includes a first-stage unlocking mechanism. The first-stage unlocking mechanism is disposed on the upper surface of the battery carrier plate, and in the horizontal direction, the top rod of the first-stage unlocking mechanism does not interfere with the battery tray.

[0018] By setting a primary lock unlocking mechanism and a secondary lock unlocking mechanism on the battery carrier plate, multi-level unlocking of the locking mechanism relative to the electric vehicle is achieved, avoiding mis-locking. Among them, the primary lock unlocking mechanism is used for pre-unlocking and does not require a drive mechanism for moving the push rod up and down. Its structure is simpler than that of the secondary lock unlocking mechanism, and therefore there is sufficient height space on the upper surface of the battery carrier plate.

[0019] Preferably, the unlocking mechanism includes a push rod, a transmission part, and a power source. The push rod is arranged in a vertical direction and connected to the power source through the transmission part. The transmission part is used to transmit the driving force of the power source in the first horizontal direction to the push rod and drive the push rod to move in the vertical direction.

[0020] The power source of this unlocking mechanism outputs driving force outward along the first horizontal direction, which avoids the power source being too large and affecting the installation space of the unlocking mechanism on the side of the battery support plate, thus achieving a compact layout. At the same time, a transmission unit is provided to change the driving force of the power source along the first horizontal direction to the vertical direction and transmit it to the top rod, so as to realize the lifting and lowering of the top rod, thereby achieving the unlocking purpose.

[0021] Preferably, the transmission unit includes a connecting rod, a first guide rail, and a second guide rail. The first guide rail is arranged along the first horizontal direction, and the second guide rail is arranged along the vertical direction. The first end of the connecting rod is movably connected to the power source and can reciprocate along the first horizontal direction on the first guide rail. The second end of the connecting rod is movably connected to the top rod and can reciprocate along the vertical direction on the second guide rail.

[0022] By using a linkage structure, the force is transmitted along the axial direction through a single rod, converting the horizontal driving force output from the power source into the vertical movement of the push rod. Compared to other transmission schemes, transmission via linkage is more reliable. Furthermore, due to its relatively simple structure, it avoids the problem of excessively large linkage dimensions affecting the installation space of the unlocking mechanism on the side of the battery support plate.

[0023] Preferably, the unlocking mechanism further includes a guide member, and the push rod passes through the through hole of the guide member. The guide member is used to restrict the degree of freedom of the push rod in the horizontal direction.

[0024] By setting guides to restrict the horizontal movement of the push rod, the push rod can maintain precise vertical movement, thus improving unlocking accuracy.

[0025] Preferably, the power source is an electric actuator.

[0026] An electric actuator is used as the power source, and its high positional accuracy is utilized to improve the unlocking accuracy of the unlocking mechanism.

[0027] Preferably, the unlocking mechanism further includes a first positioning sensor, which is disposed near the first end of the connecting rod and is used to detect the positioning status of the first end of the connecting rod.

[0028] Preferably, the unlocking mechanism further includes a second positioning sensor, which is disposed near the second end of the connecting rod and is used to detect the positioning status of the second end of the connecting rod.

[0029] By setting a first or second positioning sensor, the positioning status of the first or second end of the connecting rod can be detected respectively. Since the positioning status of the first or second end of the connecting rod can directly reflect the lifting status of the push rod, active detection of the lifting status of the push rod can be achieved.

[0030] In the case of simultaneously setting up a first positioning sensor and a second positioning sensor, if one positioning sensor detects positioning while the other does not, it indicates that one of the positioning sensors is faulty. Therefore, setting up two positioning sensors simultaneously can improve detection reliability.

[0031] Preferably, the unlocking mechanism further includes a mechanism frame for accommodating the transmission unit, the mechanism frame having open sides.

[0032] By setting up a mechanism frame to house the connecting rods, the moving parts are protected from damage. At the same time, the open sides of the mechanism frame facilitate the installation and maintenance of the transmission components it houses.

[0033] Preferably, the mechanism frame is used to accommodate the connecting rod, and the first guide rail and the second guide rail are formed on the side of the mechanism frame.

[0034] The first and second guide rails are formed on the side of the mechanism frame, which guides the two ends of the two rods, making the structure more compact.

[0035] Preferably, the bottom of the mechanism frame extends toward and connects to the power source.

[0036] By fixing the power source with a structural frame, the overall structural integration of the unlocking mechanism can be improved.

[0037] The positive and progressive effects of this invention are as follows:

[0038] This battery swapping device connects the unlocking mechanism to the side of the battery carrier plate of the battery swapping platform, thereby utilizing the side space of the battery carrier plate to accommodate the unlocking mechanism. This effectively solves the problem that the unlocking mechanism is too large and can only be set on the upper surface of the base.

[0039] The unlocking mechanism is connected to the battery support plate and adjusts its position synchronously with the battery support plate to achieve alignment with the locking mechanism of the electric vehicle. Therefore, there is no need to set up an additional drive mechanism to adjust the horizontal position of the unlocking mechanism separately, which effectively simplifies the structure of the battery swapping equipment and makes the battery swapping control process relatively simple.

[0073] The present invention will be described more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.

[0074] Example 1

[0075] like Figure 1 , Figure 2 and Figure 3As shown, the present invention provides a battery swapping device 100, which includes a battery swapping platform 10, a lifting drive mechanism 20, and a horizontal movement mechanism 30. The battery swapping platform 10 is connected to the horizontal movement mechanism 30 via the lifting drive mechanism 20. The battery swapping platform 10 carries a battery pack 200. The lifting drive mechanism 20 drives the battery swapping platform 10 and the battery pack 200 to move up and down in the vertical direction A, so as to install and remove the battery pack 200 relative to the chassis of an electric vehicle. The horizontal movement mechanism 30 drives the battery swapping platform 10 and the battery pack 200 to move horizontally in the travel direction B, so as to realize the horizontal transport of the battery pack 200.

[0076] Specifically, such as Figure 2 and Figure 3 As shown, the battery swapping platform 10 includes a battery tray 1, a battery support plate 2, a vehicle connection plate 3, a base 4, a displacement adjustment mechanism 5, and an unlocking mechanism 6. The base 4 is located at the bottom of the entire battery swapping platform 10 and is connected to the lifting drive mechanism 20. The battery support plate 2 and the vehicle connection plate 3 are located above the base 4 and are connected to the base 4 via the displacement adjustment mechanism 5. The displacement adjustment mechanism 5 drives the battery support plate 2 and the vehicle connection plate 3 to reciprocate along the adjustment direction C to adjust their horizontal position relative to the electric vehicle. The adjustment direction C is perpendicular to the travel direction B of the horizontal movement mechanism 30. The battery tray 1 is located above the battery support plate 2 and is used to directly contact the battery pack 200 to support the battery pack 200. The battery tray 1 and the battery support plate 2 are elastically connected in the vertical direction A to prevent the impact force generated by placing the battery pack 200 from being transmitted to the battery support plate 2. Simultaneously, the battery tray 1 and the battery support plate 2 are positioned and connected in the horizontal adjustment direction C to transmit the horizontal displacement of the battery support plate 2 to the battery tray 1, thereby adjusting the horizontal position of the battery pack 200. The displacement adjustment mechanism 5 adjusts the horizontal position of the battery support plate 2 so that the battery pack 200 can be aligned with the battery swapping position of the vehicle to be swapped. The vehicle connecting plate 3 is used for positioning and connecting to the vehicle to be swapped. Through the cooperation of the battery support plate 2 and the vehicle connecting plate 3, the purpose of attaching and detaching the battery pack 200 from the vehicle to be swapped is achieved. The unlocking mechanism 6 drives the push rod to move upward in the vertical direction A to open the locking linkage of the locking mechanism used to fix the battery pack 200 on the electric vehicle, thus achieving the unlocking purpose.

[0077] like Figure 3 and Figure 4 As shown, in this embodiment, two unlocking mechanisms 6 are respectively arranged on the left and right sides of the battery carrier plate 2 along the travel direction B, and are respectively connected to the battery carrier plate 2. By arranging the unlocking mechanisms 6 on the side of the battery carrier plate 2, the side space of the battery carrier plate 2 is used to accommodate the unlocking mechanisms 6, effectively solving the problem that the height of the unlocking mechanisms 6 is too large and can only be set on the upper surface of the base 4.

[0078] Meanwhile, the battery support plate 2 is used to support the battery pack 200, and will adjust the position of the locking mechanism relative to the electric vehicle along the adjustment direction C under the drive of the displacement adjustment mechanism 5. By connecting the unlocking mechanism 6 to the battery support plate 2, the unlocking mechanism 6 can adjust its position synchronously with the battery support plate 2 to achieve alignment with the locking mechanism of the electric vehicle. Therefore, there is no need to set up other drive mechanisms to adjust the horizontal position of the unlocking mechanism 6 separately, which can effectively simplify the structure of the battery swapping equipment and make the battery swapping control process relatively simple.

[0079] Specifically, in this embodiment, there are two unlocking mechanisms 6, which are distributed on both sides of the battery carrier plate 2. In other embodiments, the number of unlocking mechanisms 6 can also be set according to actual needs.

[0080] like Figure 5 As shown, the unlocking mechanism 6 is located below the battery tray 1. To prevent the battery tray 1 from affecting the upward movement of the top rod 61 of the unlocking mechanism 6, first hollow portions 11 are provided on both sides of the battery tray 1 to correspond to the positions of the top rods 61 of the two unlocking mechanisms 6, allowing the top rods 61 to extend upward from the first hollow portions 11, thus preventing interference between the top rods 61 of the unlocking mechanism 6 and the battery tray 1. In other embodiments, the top rods 61 of the unlocking mechanism 6 can also be horizontally offset from the battery tray 1 by adjusting the position of the unlocking mechanism 6 or reducing the size of the battery tray 1.

[0081] In this embodiment, an adapter rod is provided inside the battery pack 200 along the vertical direction A. The top rod 61 extends upward through the first hollow part 11 of the battery tray 1 and contacts the bottom of the adapter rod of the battery pack 200, pushing the adapter rod to rise. The top of the adapter rod contacts the locking mechanism of the electric vehicle to unlock it.

[0082] In this embodiment, as Figure 6 As shown, the battery swapping platform 10 also includes two primary lock unlocking mechanisms 8. The primary lock unlocking mechanism 8 has a relatively simple structure. Its top rod 81 is located at a high position and does not have lifting capability. Therefore, the primary lock unlocking mechanism 8 can be set on the upper surface of the battery support plate 2.

[0083] Based on the aforementioned unlocking mechanism 6 as a secondary lock unlocking mechanism, a primary lock unlocking mechanism 8 is further provided to achieve multi-level unlocking of the electric vehicle's locking mechanism and avoid mis-locking. The primary lock unlocking mechanism 8 is used for pre-unlocking and does not require a drive mechanism for the up-and-down movement of the drive rod 81. Its structure is simpler than the secondary lock unlocking mechanism (unlocking mechanism 6), and therefore it has sufficient height space on the upper surface of the battery support plate 2.

[0084] like Figure 5As shown, the primary lock unlocking mechanism 8 is also located below the battery tray 1. Second hollow portions 12 are provided on both sides of the battery tray 1, allowing the top rods 81 of the two primary lock unlocking mechanisms 8 to extend from the second hollow portions 12. In other embodiments, the top rods 81 of the primary lock unlocking mechanism 8 can be horizontally offset from the battery tray 1 by adjusting the position of the primary lock unlocking mechanism 8 or reducing the size of the battery tray 1.

[0085] This embodiment further provides a preferred structural arrangement for the unlocking mechanism 6: such as Figure 7 and Figure 8 As shown, the unlocking mechanism 6 includes a push rod 61, a transmission part 62, a power source 63, and a mechanism frame 67. The mechanism frame 67 houses the transmission part 62 and protects its linkage structure. The push rod 61 is positioned vertically A and connected to the power source 63 via the transmission part 62. The transmission part 62 transmits the driving force of the power source 63 along the first horizontal direction (i.e., the adjustment direction C in this embodiment) to the push rod 61, driving the push rod 61 to move up and down along the vertical direction A. By outputting driving force outward along the horizontal adjustment direction C, the power source 63 of this unlocking mechanism 6 avoids excessive height from affecting the installation space of the unlocking mechanism 6 on the side of the battery support plate 2, achieving a compact layout. Simultaneously, the transmission part 62 changes the driving force of the power source 63 along the adjustment direction C to the vertical direction A and transmits it to the push rod 61, thereby enabling the lifting and lowering of the push rod 61 and achieving the unlocking purpose. In this embodiment, the power source 63 is implemented by an electric actuator. The high positional accuracy of the electric actuator improves the unlocking accuracy of the unlocking mechanism 6.

[0086] Specifically, the transmission unit 62 includes a connecting rod 621, a first guide rail 622, and a second guide rail 623. The first guide rail 622 is arranged along the horizontal adjustment direction C, while the second guide rail 623 is arranged along the vertical direction A. The first end 6211 of the connecting rod 621 is movably connected to the power source 63 and can reciprocate along the adjustment direction C on the first guide rail 622, guiding it. The second end 6212 of the connecting rod 621 is movably connected to the top rod 61 and can reciprocate along the vertical direction A on the second guide rail 623. In this embodiment, the transmission unit 62 transmits force along the axial direction through a single rod, converting the horizontal driving force output by the power source 63 into vertical movement of the top rod 61. Compared to other transmission schemes, transmission via the connecting rod 621 offers higher reliability. Furthermore, due to its relatively simple structure, it avoids the connection rod 621's excessive height affecting the space available for the unlocking mechanism 6 on the side of the battery support plate 2. In this embodiment, as... Figure 7As shown, a first guide rail 622 and a second guide rail 623 are formed on the side of the mechanism frame 67. A first guide rail 622 is formed by providing a slot extending in the adjustment direction C on the side of the mechanism frame 67 to accommodate the first end 6211 of the connecting rod 621, thus guiding the first end 6211 of the connecting rod 621. A second guide rail 623 is formed by providing a slot extending in the vertical direction A on the side of the mechanism frame 67 to accommodate the second end 6212 of the connecting rod 621, thus guiding the second end 6212 of the connecting rod 621. By utilizing the mechanism frame 67 to guide both ends of the two rods, the unlocking mechanism 6 can be made more compact.

[0087] In addition, a guide 64 is provided at the top of the mechanism frame 67. The push rod 61 passes through the through hole of the guide 64 to restrict the horizontal movement freedom of the push rod 61, so that the push rod 61 can maintain precise vertical movement and improve unlocking accuracy.

[0088] In this embodiment, as Figure 8 As shown, the main body of the mechanism frame 67 is composed of a frame-shaped structure. The connecting rod 621 of the transmission part 62 is disposed inside the mechanism frame 67. As can be seen from the figure, the left and right sides of the mechanism frame 67 are open. Specifically, the left side of the mechanism frame 67 is open to allow the power source 63 to extend and connect with the connecting rod 621, and the right side of the mechanism frame 67 is open to facilitate the installation of the connecting rod 621 and to facilitate the maintenance of the connecting rod 621. In addition, in this embodiment, the bottom of the mechanism frame 67 extends towards the power source 63 and is connected to the power source 63 to fix the power source 63 through the structural frame, making the entire unlocking mechanism 6 structurally integrated.

[0089] like Figure 7 As shown, the unlocking mechanism 6 also includes a first positioning sensor 65 and a second positioning sensor 66. The first positioning sensor 65 is located on the first guide rail 622 on the side of the mechanism frame 67, near the first end 6211 of the connecting rod 621, and is used to detect the positioning status of the first end 6211 of the connecting rod 621. The second positioning sensor 66 is located on the second guide rail 623 on the side of the mechanism frame 67, near the second end 6212 of the connecting rod 621, and is used to detect the positioning status of the second end 6212 of the connecting rod 621. By setting the first positioning sensor 65 or the second positioning sensor 66, the positioning status of the first end 6211 or the second end 6212 of the connecting rod 621 can be detected respectively. Since the positioning status of the first end 6211 or the second end 6212 of the connecting rod 621 directly reflects the lifting status of the top rod 61, active detection of the lifting status of the top rod 61 can be achieved.

[0090] In the case where both the first positioning sensor 65 and the second positioning sensor 66 are simultaneously provided, if one positioning sensor detects a positioning status while the other does not, it indicates that one of the positioning sensors is damaged. Therefore, providing two positioning sensors simultaneously can improve detection reliability. Of course, in other embodiments, depending on actual needs, only the first positioning sensor 65 can be provided to detect the positioning status of the first end 6211 of the connecting rod 621, or only the second positioning sensor 66 can be provided to detect the positioning status of the second end 6212 of the connecting rod 621.

[0091] like Figure 4 and Figure 9 As shown, the battery swapping platform 10 in this embodiment also includes an adapter plate 7, which enables a reliable connection between the unlocking mechanism 6 and the battery carrier plate 2. Specifically, as shown... Figure 10 As shown, the adapter plate 7 has a first mounting surface 71 and a second mounting surface 72 arranged at an angle to each other. The first mounting surface 71 is used to connect to the upper surface of the battery carrier plate 2 near the side, while the second mounting surface 72 is used to connect to the side of the mechanism frame 67 of the unlocking mechanism 6. Connecting the first mounting surface 71 of the adapter plate 7 to the upper surface of the battery carrier plate 2 near the side facilitates the disassembly and maintenance of the adapter plate 7 and the battery carrier plate 2. Furthermore, as... Figure 11 As shown, each adapter plate 7 is also provided with two reinforcing members 73. The two sides of each reinforcing member 73 are respectively connected to the first mounting surface 71 and the second mounting surface 72 of the adapter plate 7, so as to use the reinforcing members 73 to strengthen the first mounting surface 71 and the second mounting surface 72 of the adapter plate 7 and avoid deformation during continuous use.
