Description

Technical Field

[0001] This invention relates to the field of vehicle battery swapping technology, specifically to a stacking battery swapping integrated machine and a battery swapping station. Background Technology

[0002] Current battery swapping stations typically consist of battery swapping equipment and a stacker crane. The battery swapping equipment is used to replace battery packs for battery swapping vehicles, while the stacker crane is used to transport battery packs.

[0003] When replacing battery packs for battery swapping vehicles at existing battery swapping stations, the exchange of battery packs between the swapping equipment and the stacker crane is an essential process. The process of exchanging battery packs between the swapping equipment and the stacker crane is roughly as follows: First, the swapping equipment is moved to the vicinity of the stacker crane. Then, the fully charged battery packs on the stacker crane are transferred to the swapping equipment, or the depleted battery packs on the swapping equipment are transferred to the stacker crane for transport.

[0004] The existing battery swapping stations require space for battery swapping equipment and stacker cranes, as well as space for the interaction of battery packs between the two, resulting in a large site area. Furthermore, the process of exchanging battery packs between the battery swapping equipment and the stacker crane reduces the battery swapping efficiency. Summary of the Invention

[0005] To address the technical problems of existing battery swapping stations having large footprints and low swapping efficiency, the first objective of this application is to propose an integrated stacking battery swapping machine. This integrated stacking battery swapping machine integrates the battery mounting mechanism of the swapping equipment onto the extension mechanism of the stacker crane. The battery mounting mechanism can move with the stacker crane and can be raised, lowered, extended, and retracted on the stacker crane, thus realizing the battery swapping and stacking functions in an integrated structure. Therefore, this application eliminates the interaction between the swapping equipment and the stacker crane on the battery pack. The battery swapping station does not need to set up an interaction space between the stacker crane and the swapping equipment for the battery pack; only the equipment space of the stacker crane needs to be set up, reducing the site area occupied by the battery swapping station and improving the swapping efficiency.

[0006] The second objective of this application is to propose a battery swapping station that includes the aforementioned stacked battery swapping unit, which has a small footprint and high battery swapping efficiency.

[0007] To achieve the above objectives, this application adopts the following technical solution:

[0008] A stacking battery swapping integrated machine includes a frame, an extension mechanism, and a battery mounting mechanism, wherein: the frame is arranged in a vertical direction; the extension mechanism is disposed on the frame and can extend or retract relative to the frame in a telescopic direction; the battery mounting mechanism is mounted on the extension mechanism, and the extension mechanism can drive the battery mounting mechanism to extend out of the frame, thereby performing chassis battery swapping for battery swapping vehicles.

[0009] The battery pack replacement process is as follows: the extension mechanism drives the battery mounting mechanism located on it to extend and retract the frame. When the battery mounting mechanism extends out of the frame with the extension mechanism, it can enter the bottom of the battery swapping vehicle. The battery mounting mechanism then positions and unlocks the battery pack on the chassis of the battery swapping vehicle to complete the battery pack replacement.

[0010] Thus, this application integrates the battery mounting mechanism and frame, which not only has stacking function but also battery swapping function. It eliminates the interaction between battery swapping equipment and stacker crane on battery pack. The battery swapping station does not need to set up interaction space between stacker crane and battery swapping equipment to interact with battery pack. Only the equipment space of stacker crane needs to be set up, which reduces the site area occupied by the battery swapping station and improves the battery swapping efficiency of the battery swapping station.

[0011] As an optional implementation of the stacking battery swapping integrated machine, the stacking battery swapping integrated machine also includes a support mechanism connected to the frame; the frame is configured to rotate relative to the support mechanism about a vertical direction, thereby driving the extension mechanism to rotate left and right relative to the telescopic direction.

[0012] Therefore, when the frame rotates relative to the support mechanism in the vertical direction, the extension mechanism can rotate left and right relative to the extension direction as the frame rotates. The battery mounting mechanism can then rotate with the extension mechanism, adjusting the rotation angle to adapt to various parking states of the battery swapping vehicle. This allows for more precise unlocking and disengagement of the battery pack and more accurate positioning of the battery mounting mechanism and the battery pack, preventing damage to the battery pack. It also reduces the requirements of the battery swapping station on the parking position and angle of the battery swapping vehicle, making parking more difficult for the driver.

[0013] As an optional implementation of the stacking battery swapping integrated machine, the support mechanism further includes a first support member and a second support member. Along the extension and retraction direction of the extension mechanism, the first support member and the second support member are respectively connected to both sides of the frame. The first support member is rotatably connected to one side of the frame, and the second support member is slidably connected to the other side of the frame, so that the frame can rotate with the connection point with the first support member as the fulcrum.

[0014] Thus, when the second support slides with the frame, the frame can rotate around the connection point with the first support, turning sliding into rotation. The first and second supports can provide support on both sides of the frame, ensuring the balance of the frame structure and improving the stability of the battery swapping process, while not affecting the left and right rotation of the frame.

[0015] As an optional implementation of the stacking battery swapping integrated machine, the frame is further provided with a first connector on one side, and the first connector is connected to the first support member through a rotating assembly; wherein, the rotating assembly includes a fixed part and a rotating part that cooperate with each other and can rotate relative to each other, the rotating part is connected to the first connector, and the fixed part is connected to the first support member, so that the rotation of the rotating part relative to the fixed part can drive the first connector to rotate relative to the first support member.

[0016] Thus, by setting a rotating component on one side of the frame, rotation between the frame and the first support member can be achieved. The rotating component includes a fixed part and a rotating part that can rotate relative to each other, and the structure is simple and reliable.

[0017] As an optional implementation of the stacking battery swapping integrated machine, the other side of the frame is provided with a second connector, which is connected to the second support member through a sliding assembly. The sliding assembly includes a guide portion and a sliding portion that can slide relative to each other. The sliding portion is connected to the second connector, and the guide portion is connected to the second support member. Thus, the sliding portion relative to the guide portion can drive the second connector to slide relative to the second support member.

[0018] Thus, by setting a sliding component on the other side of the frame, the sliding between the frame and the second support can be achieved. The sliding component includes a guide part and a sliding part that can slide relative to each other, and the structure is simple and reliable.

[0019] As an optional implementation of the stacking battery swapping integrated machine, a movable plate is provided above the second support member, and a sliding assembly is provided between the movable plate and the second support member. A second connector is provided on the other side of the frame. The second connector is located above the movable plate and is connected to the movable plate through a rotating assembly, so that the second connector can rotate relative to the second support member while sliding relative to it.

[0020] In this way, the second support member can both slide relative to the frame and rotate relative to the frame, thereby increasing the range of movement of the frame relative to the second support member and preventing the frame from jamming and wearing out during the movement of the frame relative to the second support member.

[0021] As an alternative implementation of the stacking battery swapping integrated machine, the sliding assembly further includes a driving unit connected to the sliding unit to drive the sliding unit to slide relative to the guide unit.

[0022] In this way, the driving part can drive the sliding part to slide relative to the guide part, thereby realizing the sliding between the frame and the second support member.

[0023] As an optional implementation of the stacking battery swapping integrated machine, the first support member and / or the second support member are further provided with traveling wheels to drive the stacking battery swapping integrated machine to move, thereby realizing the overall movement of the stacking battery swapping integrated machine in the horizontal direction, which is convenient to adapt to battery swapping vehicles parked in different positions in the horizontal direction and reduces the parking requirements of battery swapping vehicles.

[0024] As an optional implementation of the stacking battery swapping integrated machine, the first support member and / or the second support member are further provided with a limiting part, which cooperates with the external bottom structure to guide the movement direction of the frame from the bottom.

[0025] As an optional implementation of the stacking battery swapping integrated machine, the stacking battery swapping integrated machine also includes a pitching mechanism. The top of the frame has a horizontally extending crossbeam. The pitching mechanism is disposed between the crossbeam and the external top surface structure, so that the frame can swing up and down relative to the external top surface structure about the extension direction of the crossbeam, thereby the frame can drive the extension mechanism to tilt up and down relative to the extension direction.

[0026] In this way, the frame can tilt up and down, making its center of gravity adjustable to counteract the deflection of the extension mechanism. Specifically, by adjusting the pitch mechanism, the frame swings up and down around the extension direction of the crossbeam, correcting the tilt of the extension mechanism. Therefore, when the extension mechanism carries the battery pack, it will not tilt forward or downward due to the weight of the battery pack, nor will it tilt forward or downward during extension or backward retraction. When the battery pack leaves the extension mechanism, it will not tilt backward or downward due to the loss of its weight. This ensures that the extension mechanism remains horizontal, and consequently, the battery mounting mechanism and battery pack remain horizontal.

[0027] As an optional implementation of the stacking battery swapping integrated machine, the pitching mechanism further includes a first connecting shaft and a cam. One end of the first connecting shaft passes through the crossbeam and is rotatable relative to the crossbeam, while the other end is connected to the cam. The end of the cam away from the first connecting shaft is connected to the external top surface structure, so that when the first connecting shaft rotates relative to the crossbeam and drives the cam to rotate, it can drive the frame to swing up and down.

[0028] Thus, the end of the cam furthest from the first connecting shaft is connected to the external top surface structure. When the first connecting shaft rotates, the end of the cam furthest from the second connecting shaft will not deviate from the external top surface structure. When the first connecting shaft rotates relative to the crossbeam, the cam will rotate around the connection point with the external top surface structure, thereby causing the first connecting shaft to shift from the external top surface structure, which in turn causes the crossbeam to shift from the external top surface structure. In other words, the top of the frame can shift. Since the bottom position of the frame is fixed, the frame can swing up and down, so the extension mechanism can tilt up and down, and the center of gravity of the frame can be adjusted.

[0029] As an optional implementation of the stacking battery swapping integrated machine, the pitching mechanism further includes a second connecting shaft and a sliding wheel. One end of the second connecting shaft is connected to the end of the cam away from the first connecting shaft, and the other end is rotatably connected to the sliding wheel. The sliding wheel is limited and cooperates with the external top surface structure to guide the movement direction of the frame from the top.

[0030] Therefore, since the sliding wheel can rotate relative to the second connecting shaft, the sliding wheel will not affect the rotation of the cam when it slides along the outer top surface structure. The cam can move along the outer top surface structure, so that the frame can move along the outer top surface structure without affecting the up and down swing of the stacking battery swapping machine.

[0031] As an alternative implementation of the stacking battery swapping integrated machine, the second connecting shaft is further spherically hinged to the sliding wheel.

[0032] In this way, the second connecting shaft and the pulley can rotate 360°, preventing the first connecting shaft and the second connecting shaft from being twisted off.

[0033] As an optional implementation of the stacking battery swapping integrated machine, the battery mounting mechanism is movably mounted on the extension mechanism, and the movement direction of the battery mounting mechanism is perpendicular to the extension direction of the extension mechanism. Therefore, the stacking battery swapping integrated machine can adjust the extension distance of the extension mechanism and the movement distance of the battery mounting mechanism in a direction perpendicular to the extension direction, making the battery mounting mechanism adjustable in two directions on the horizontal plane, thereby adapting to the position of the battery swapping vehicle for battery swapping.

[0034] As an optional implementation of the stacking battery swapping integrated machine, the battery mounting mechanism is further provided with unlocking components for locking and unlocking the battery pack of the battery swapping vehicle and / or positioning components for positioning the battery pack of the battery swapping vehicle.

[0035] One technical solution for a battery swapping station proposed in this application is as follows:

[0036] A battery swapping station includes any of the aforementioned stacked battery swapping integrated machines.

[0037] As an alternative implementation of the battery swapping station, the station further includes a bottom structure having a first track for engaging with a limiting part of the stacked battery swapping unit to guide the stacked battery swapping unit to move along the first track; and / or, the station further includes a top structure having a second track for engaging with a sliding wheel of the stacked battery swapping unit to guide the stacked battery swapping unit to move along the second track.

[0038] The beneficial effects of this application are as follows:

[0039] This application integrates the battery mounting mechanism of the battery swapping equipment onto the extension mechanism of the stacker crane. The battery mounting mechanism can move with the stacker crane and can be raised, lowered, extended, and retracted on the stacker crane, thus realizing the battery swapping and stacking functions in an integrated structure. Therefore, this application eliminates the interaction between the battery swapping equipment and the stacker crane on the battery pack. The battery swapping station does not need to have an interaction space for the stacker crane and the battery swapping equipment to interact with the battery pack; only the equipment space of the stacker crane is required, reducing the site area occupied by the battery swapping station and improving the battery swapping efficiency.

[0059] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate components with the same or similar structures but the same function.

[0060] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0061] Reference Figure 1 In a specific embodiment of this application, the battery swapping station includes a stacking battery swapping unit a, a first track 6 at the bottom, and a second track 7 at the top. The first track 6 and the second track 7 are arranged in parallel and extend in the direction of arrow X in the figure. The stacking battery swapping unit a is located between the first track 6 and the second track 7. The top of the stacking battery swapping unit a can slide with the second track 7, and the bottom of the stacking battery swapping unit a can slide with the first track 6, so that the stacking battery swapping unit a can move along the extension direction of the first track 6 and the second track 7.

[0062] In other specific embodiments of this application, the battery swapping station may only have a first track 6 or only a second track 7.

[0063] Specifically, refer to Figure 1 In a specific embodiment of this application, the stacking battery swapping integrated machine a includes a stacker crane and a battery installation mechanism 3. The stacker crane is used to transport battery packs, and the battery installation mechanism 3 is used to replace battery packs for battery swapping vehicles. The battery installation mechanism 3 is located on the stacker crane. The stacker crane includes a frame 1 and an extension mechanism 2. The frame 1 is arranged vertically, and the extension mechanism 2 can be formed by the stacker crane's forks. The extension mechanism 2 is located on the frame 1 and can extend or retract in the telescopic direction. The telescopic direction of the extension mechanism 2 is set along arrow Y, that is, the extension mechanism 2 can extend or retract in the telescopic direction. Figure 1 The battery mounting mechanism 3 moves back and forth in the Y direction and is located on the extension mechanism 2. The extension mechanism 2 can drive the battery mounting mechanism 3 located on it to extend and retract from the frame 1. When the battery mounting mechanism 3 extends out of the frame 1 with the extension mechanism 2, it can enter the bottom of the battery swapping vehicle. The battery mounting mechanism 3 can then position and unlock the battery pack on the chassis of the battery swapping vehicle to complete the replacement of the battery pack.

[0064] Specifically, refer to Figure 1 The specific implementation method for enabling the stacking battery swapping integrated machine a to move along the extension direction of the first track 6 and the second track 7 can be as follows: Frame 1 is a component that can support and connect the various parts of the stacking battery swapping integrated machine. The bottom of frame 1 is slidably engaged with the first track 6, and the top of frame 1 is slidably engaged with the second track 7. In this way, frame 1 can move along the extension direction of the first track 6 and the second track 7, that is: frame 1 can move along... Figure 1 The stacking battery swapping machine a moves back and forth in the X direction, thereby enabling it to move along the extension direction of the first track 6 and the second track 7.

[0065] Among them, reference Figure 1 The extension directions of the first track 6 and the second track 7 are perpendicular to the extension and retraction directions of the extension mechanism 2, that is, the X direction is perpendicular to the Y direction. When the frame 1 moves back and forth in the X direction, it can drive the extension mechanism 2 and the battery mounting mechanism 3 to move. When the extension mechanism 2 moves back and forth in the Y direction, it can drive the battery mounting mechanism 3 to move. Thus, the battery mounting mechanism 3 has movement in both the X and Y directions, which facilitates the positioning and unlocking of the battery pack of the battery swapping vehicle chassis. The battery mounting mechanism 3 does not need to be equipped with a moving mechanism that moves relative to the extension mechanism 2 in the X and Y directions, which simplifies the structure of the battery mounting mechanism 3.

[0066] In other specific embodiments of this application, the battery mounting mechanism 3 can also move relative to the extension mechanism 2 in the X direction, that is, the battery mounting mechanism 3 is movably mounted on the extension mechanism 2. This arrangement allows the frame 1 to achieve coarse positioning with the battery swapping vehicle in the X direction through the movement of the first track 6 and the second track 7, while the movement of the battery mounting mechanism 3 relative to the extension mechanism 2 achieves fine positioning with the battery swapping vehicle in the X direction. This enables precise control of the positioning and unlocking / unlocking between the battery mounting mechanism 3 and the battery pack. Simultaneously, the battery mounting mechanism 3 can also cooperate with the frame 1 and the extension mechanism 2 to complete multi-level unlocking / unlocking in the same direction.

[0067] In other embodiments of this application, the battery mounting mechanism 3 is also capable of moving relative to the extension mechanism 2 in the Y direction.

[0068] In other embodiments of this application, the battery mounting mechanism 3 is also capable of vertical movement relative to the extension mechanism 2.

[0069] In other specific embodiments of this application, the battery mounting mechanism 3 may be provided with an unlocking component for unlocking and / or a positioning component for positioning the battery pack of the battery swapping vehicle. When the battery mounting mechanism 3 moves independently or moves with the frame 1 and the extension mechanism 2, the unlocking component and / or the positioning component can cooperate with the quick-change bracket and / or battery pack of the battery swapping vehicle to complete the unlocking and / or positioning.

[0070] Reference Figure 1 In one specific embodiment of this application, the stacking battery swapping integrated machine a can also be along... Figure 1 The arrow Q in the image rotates left and right, as shown below:

[0071] Reference Figure 1 In a specific embodiment of this application, the stacking battery swapping integrated machine a further includes a support mechanism 4, which is connected to the frame 1; the frame 1 is configured to rotate relative to the support mechanism 4 in a vertical direction, thereby driving the extension mechanism 2 to rotate left and right relative to the extension direction around arrow Q.

[0072] Therefore, when frame 1 rotates relative to support mechanism 4 in the vertical direction, extension mechanism 2 can move along the extension direction with frame 1. Figure 1 Arrow Q in the diagram enables left and right rotation, allowing the battery mounting mechanism 3 to rotate along with the extension mechanism 2, thus adjusting the rotation angle to adapt to various parking conditions of the battery swapping vehicle. This makes the unlocking and unlocking of the battery pack and the positioning of the battery mounting mechanism 3 with the battery pack more precise, avoiding damage to the battery pack. At the same time, it reduces the requirements of the battery swapping station on the parking position and angle of the battery swapping vehicle, and reduces the difficulty of parking for the driver.

[0073] Reference Figure 2-7 In a specific embodiment of this application, the support mechanism 4 further includes a first support member 41 and a second support member 42. Along the extension and retraction direction of the extension mechanism 2, the first support member 41 and the second support member 42 are respectively connected to both sides of the frame 1. The first support member 41 is rotatably connected to one side of the frame 1, and the second support member 42 is slidably connected to the other side of the frame 1, so that the frame 1 can rotate with the connection point with the first support member 41 as the fulcrum.

[0074] Thus, when the second support member 42 slides against the frame 1, the frame 1 can rotate around the connection point with the first support member 41, changing the sliding into rotation. The first support member 41 and the second support member 42 can provide support on both sides of the frame 1, ensuring the balance of the frame 1 structure and thus improving the stability of the battery swapping process, while not affecting the left and right rotation of the frame 1 around arrow Q.

[0075] Reference Figure 3 In a specific embodiment of this application, a first connector 11 is provided on one side of the frame 1. The first connector 11 is connected to the first support member 41 through a rotating assembly R13. The rotating assembly includes a fixed part and a rotating part that cooperate with each other and can rotate relative to each other. The rotating part is connected to the first connector 11, and the fixed part is connected to the first support member 41. Thus, the rotation of the rotating part relative to the fixed part can drive the first connector 11 to rotate relative to the first support member 41.

[0076] Therefore, Figure 2 and Figure 3 In the direction shown in the diagram, the first connector 11 is connected to the left side of the frame 1. The first connector 11 is rotatably connected to the first support member 41 through the rotating component R13. The first connector 11 is connected to the rotating part of the rotating component R13. The first support member 41 is connected to the fixed part. The rotating part and the fixed part can rotate relative to each other so that the first connector 11 and the first support member 41 can rotate relative to each other.

[0077] In a specific embodiment of this application, the rotating component R13 can be a rotary bearing. In other specific embodiments, the rotating component can be other rotatable structures, such as balls, shafts, etc.

[0078] In other specific embodiments, the first connector 11 can be connected to the fixed part of the rotating assembly R13, and the first support 41 can be connected to the rotating part.

[0079] Reference Figure 5 and Figure 7In a specific embodiment of this application, a second connector 12 is further provided on the other side of the frame 1. The second connector 12 is connected to the second support member 42 via a sliding assembly 14. The sliding assembly 14 includes a guide portion 141 and a sliding portion 142 that are slidably oriented relative to each other.

[0080] The guide portion 141 is connected to the second connecting member 12 and the guide portion 141 is connected to the second support member 42. Thus, the sliding portion 142 can slide relative to the guide portion 141, thereby driving the second connecting member 12 to slide relative to the second support member 42.

[0081] Therefore, refer to Figure 5 and Figure 7 In the direction shown in the diagram, the second connector 12 is connected to the right side of the frame 1. The second connector 12 is connected to the second support 42 through the sliding component 14. The second connector 12 is connected to the sliding part 142 of the sliding component 14. The second support 42 is connected to the guide part 141. The sliding part 142 and the guide part 141 can slide relative to each other, so that the second connector 12 and the second support 42 can slide relative to each other.

[0082] In a specific embodiment of this application, the sliding part 142 can be a slider, and the guide part 141 can be...

[0083] Slide rail. In other embodiments, the sliding component 14 may also be other sliding structures, such as pulleys and grooves.

[0084] In other specific embodiments, the second connector 12 may be connected to the guide portion 141, and the second support portion 42 may be connected to the sliding portion 142.

[0085] 5 Reference Figure 5 and Figure 7 In a specific embodiment of this application, the second support member 42 further...

[0086] A movable plate 43 is provided above, and a sliding assembly 14T is provided between the movable plate 43 and the second support member 42. The second connecting member 12 is located above the movable plate 43 and is connected to the movable plate 43 through a rotating assembly T44, so that the second connecting member 12 can rotate relative to the second support member 42 during the sliding process.

[0087] In this way, the second support member 42 can both slide relative to the frame 1 and rotate relative to the frame 1, thereby increasing the range of movement of the frame 1 relative to the second support member 42 and preventing the frame 1 from getting stuck and wearing out during the movement of the frame 1 relative to the second support member 42.

[0088] Reference Figure 7In a specific embodiment of this application, the sliding component 14 further includes a driving part 143, which is connected to the sliding part 142 to drive the sliding part 142 to slide relative to the guide part 141.

[0089] 5. Thus, the driving part 143 can drive the sliding part 142 to slide relative to the guide part 141, realizing the sliding between the frame 1 and the second support member 42, referring to... Figure 7 The drive unit 143 can be a lead screw motor, the guide unit 141 is the lead screw of the lead screw motor, and the sliding unit 142 can be a nut that can convert the rotation of the lead screw into linear motion.

[0090] Reference Figure 3 and Figure 5 In a specific embodiment of this application, the first support member 41 and / or the second support member 42 are provided with walking wheels 45 to drive the stacking battery swapping machine a to move, thereby realizing the overall movement of the stacking battery swapping machine in the horizontal direction, which is convenient to adapt to battery swapping vehicles parked in different positions in the horizontal direction and reduces the parking requirements of battery swapping vehicles.

[0091] Reference Figure 3 and Figure 5 In a specific embodiment of this application, the first support member 41 and / or the second support member 42 are provided with a limiting part 46, which cooperates with the external bottom structure to guide the movement direction of the frame 1 from the bottom.

[0092] Therefore, refer to Figure 3 The outer bottom structure is the first track 6, and the limiting part 46 can be a pulley that cooperates with the track groove of the first track 6, so that the pulley can only move along the first track 6, thereby realizing the movement direction of the guide frame 1 from the bottom.

[0093] Reference Figure 1 In another specific embodiment of this application, the stacking battery swapping integrated machine a can also be along... Figure 1 The arrow W in the image swings up and down, as shown below:

[0094] Reference Figure 8 and Figure 9 In a specific embodiment of this application, the stacking battery swapping integrated machine a further includes a pitching mechanism 5. The top of the frame 1 has a horizontally extending crossbeam 15. The pitching mechanism 5 is disposed between the crossbeam 15 and the external top surface structure so that the frame 1 can swing up and down relative to the external top surface structure around the extension direction of the crossbeam 15, that is, swing up and down along the arrow W. Thus, the frame 1 can drive the extension mechanism 2 to tilt up and down relative to the extension direction along the arrow W.

[0095] In this way, frame 1 can tilt up and down along arrow W, making the center of gravity of frame 1 adjustable to counteract the deflection of extension mechanism 2. Specifically, by adjusting the pitch mechanism 5, frame 1 swings up and down around the extension direction of crossbeam 15, correcting the vertical tilt of extension mechanism 2. Thus, when extension mechanism 2 carries a battery pack, extension mechanism 2 will not tilt due to the weight of the battery pack. Figure 8 The diagram shows a forward and downward tilt, and the extension mechanism 2 will not shift its center of gravity forward or downward during extension, nor will it shift its center of gravity backward during retraction. Figure 8 The diagram shows the direction tilting backward and downward; when the battery pack leaves the extension mechanism 2, the extension mechanism 2 will not tilt backward and downward due to the loss of the battery pack's weight. This ensures that the extension mechanism 2 remains horizontal, thereby ensuring that the battery mounting mechanism 3 and the battery pack remain horizontal.

[0096] Reference Figure 9 In a specific embodiment of this application, the pitch mechanism 5 further includes a first connecting shaft 51 and a cam 52. One end of the first connecting shaft 51 passes through the crossbeam 15 and can rotate relative to the crossbeam 15. The other end is connected to the cam 52. The end of the cam 52 away from the first connecting shaft 51 is connected to the external top surface structure, so that when the first connecting shaft 51 rotates relative to the crossbeam 15 and drives the cam 52 to rotate, it can drive the frame 1 to swing up and down.

[0097] Specifically, the external top surface structure can be the top surface of the battery swapping station. The end of the cam 52 away from the first connecting shaft 51 is connected to the top surface of the battery swapping station. When the first connecting shaft 51 rotates, since the end of the cam 52 away from the second connecting shaft 53 will not deviate from the top surface of the battery swapping station, when the first connecting shaft 51 rotates relative to the crossbeam 15, the cam 52 will rotate around the connection point with the top surface of the battery swapping station, thereby causing the first connecting shaft 51 to shift relative to the top surface of the battery swapping station, thereby causing the crossbeam 15 to shift relative to the top surface of the battery swapping station. That is, the top of the frame 1 can shift. Since the bottom position of the frame 1 is fixed, the frame 1 can swing up and down along the arrow W, so that the extension mechanism 2 can tilt up and down, and the center of gravity of the frame 1 can be adjusted.

[0098] In a specific embodiment of this application, a rotary motor for driving the first connecting shaft 51 to rotate is provided on the crossbeam 15, and the output shaft of the rotary motor is connected to the second connecting shaft 53 via belt drive or chain drive. In other specific embodiments, the drive structure for driving the first connecting shaft 51 to rotate may also be other drive forms.

[0099] Reference Figure 9In a specific embodiment of this application, the pitch mechanism 5 further includes a second connecting shaft 53 and a sliding wheel 54. One end of the second connecting shaft 53 is connected to the end of the cam 52 away from the first connecting shaft 51, and the other end is rotatably connected to the sliding wheel 54. The sliding wheel 54 is limited and cooperates with the external top surface structure to guide the movement direction of the top frame 1.

[0100] Specifically, the external top surface structure can be a second track 7, and the sliding wheel 54 is connected to the second track 7. Since the sliding wheel 54 can rotate relative to the second connecting shaft 53, the sliding wheel 54 will not affect the rotation of the cam 52 when it slides along the second track 7. The cam 52 can move along the second track 7 with the sliding wheel 54, so that the frame 1 can move along the second track 7 without affecting the stacking battery swapping machine a to swing up and down along the arrow W.

[0101] In another specific embodiment of this application, the second connecting shaft 53 can be spherically hinged to the sliding wheel 54. In this way, the second connecting shaft 53 and the sliding wheel 54 have 360° rotation, preventing the first connecting shaft 51 and the second connecting shaft 53 from being twisted off.

[0102] In another specific embodiment of this application, the stacking battery swapping integrated machine a may have both the above-mentioned left-right rotation along arrow Q and the above-mentioned up-down swinging motion along arrow W, or it may only have the left-right rotation along arrow Q, or it may only have the up-down swinging motion along arrow W.

Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0104] The above are merely embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
