Description

Stacker cranes and battery swapping stations

[0001] This disclosure claims priority to Chinese patent application CN202510292353.1, filed on March 12, 2025, entitled “Stacker Crane and Battery Swapping Station”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure generally relates to the technical field of battery swapping for new energy vehicles, and more specifically to a stacker crane and a battery swapping station. Background Technology

[0003] Battery swapping stations in related technologies often incorporate stacker cranes for storing, retrieving, and stacking batteries. The stacker crane includes a battery loading platform and a stacking rack. The battery loading platform is mounted on the stacking rack using at least one pair of linear guide assemblies, enabling vertical lifting relative to the stacking rack. Each pair of linear guide assemblies includes at least two slide rails. The stacking rack has slide rail mounting surfaces suitable for mounting the slide rails. To ensure that the slide rail mounting surfaces of the same pair of slide rails are on the same plane or parallel to each other, the machining accuracy requirements for the slide rail mounting surfaces are very high. If the machining accuracy of the slide rail mounting surfaces does not meet the requirements, it will increase the interaction force between the sliding parts and the slide rails, thereby reducing the service life of the slide rails and sliding parts. Summary of the Invention

[0004] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This summary section is not intended to limit the key features and essential technical features of the claimed technical solutions, nor is it intended to determine the scope of protection of the claimed technical solutions.

[0005] To at least partially solve the above-mentioned problems, a first aspect of this disclosure provides a stacker crane. The stacker crane includes a carrier rack, a stacking rack, a first guide assembly, and an adjusting connection assembly. The stacking rack has a first mounting surface extending along a first direction. The first guide assembly is connected between the stacking rack and the carrier rack to allow the carrier rack to move relative to the stacking rack along the first direction. The first guide assembly includes a first slide rail and a first sliding portion. The first slide rail is fixed to the first mounting surface and extends along the first direction. The first sliding portion is slidably connected to the first slide rail. The adjusting connection assembly is movably connected between the first sliding portion and the carrier rack to allow the first sliding portion to move relative to the carrier rack in a second direction. The first direction is vertical or substantially vertical. The second direction is perpendicular or substantially perpendicular to the first mounting surface.

[0006] According to the stacker crane of the first aspect of this disclosure, by adding an adjusting connecting assembly between the carrier rack and the first sliding part, the carrier rack is allowed to move relative to the first sliding part in a second direction. By adopting the above technical solution, the problem of non-coplanar and non-parallel mounting surfaces of a pair of slide rails, including the first slide rail, caused by insufficient machining accuracy or assembly errors can be overcome. This also helps to reduce the requirements for the machining accuracy of the mounting surfaces of the slide rails, thereby reducing production costs.

[0007] Optionally, the adjusting connection assembly includes a first connecting member and a second connecting member. The first connecting member is fixedly connected to the first sliding portion.

[0012] Optionally, the stacker crane further includes a fall arrest assembly and a chain. The fall arrest assembly includes a fall arrest housing, a fall arrest member, and a transmission connection member. The fall arrest housing is fixed to the rack. The fall arrest member is movably connected to the fall arrest housing between a fall arrest position and a clearance position. The transmission connection member is movably connected to the fall arrest housing along the first direction. The transmission connection member is linked to the fall arrest member to apply a force to the fall arrest member toward the fall arrest position. One end of the chain is connected to the transmission connection member, and the other end is connected to the fall arrest housing to drive the rack to rise and fall. In the fall arrest position, the fall arrest member contacts the stacker rack. In the clearance position, the fall arrest member disengages from the stacker rack.

[0013] Optionally, the fall arrester is rotatably connected to the fall arrest housing about a fall arrest axis between the fall arrest position and the avoidance position. The fall arrest axis does not extend in the first direction. The stacking rack has a plurality of locking holes. The plurality of locking holes are spaced apart in the vertical direction. The locking holes are adapted to accommodate the fall arrester located at the fall arrest position. One end of the fall arrester forms a latch adapted to be inserted into the locking hole.

[0014] Optionally, the transmission connection member includes a fall arrestor, a movable connector, and a follower connector. The movable connector is movably connected to the fall arrestor housing along the first direction. The movable connector is connected to one end of the chain. The follower connector is connected to the movable connector and is movably connected to the end of the fall arrestor located away from the latch. The fall arrestor is connected between the fall arrestor housing and the follower connector, and is used to apply a force to the follower connector to cause the follower connector to move relative to the fall arrestor housing along the first direction.

[0015] Optionally, the fall arrest assembly further includes an anti-rotation member. The anti-rotation member is fixed to the fall arrest housing. The anti-rotation member is used to limit the fall arrest member to the stop position.

The guide support column extends along the first direction. The guide support column passes through the guide hole.

[0017] Optionally, the stacker crane further includes a measured element and a sensing element. The measured element is disposed on the transmission connection member. The sensing element is disposed on the fall arrestor housing. When the fall arrestor is in the avoidance position, the measured element is spaced apart from the sensing element along the first direction. When the fall arrestor is in the stop position, the measured element triggers the sensing element.

[0018] Optionally, the stacker crane further includes a fall arrest assembly and a chain drive assembly. The fall arrest assembly includes a fall arresting element. The fall arresting element is rotatably connected to the carrier rack about a fall arresting axis between a fall arresting position and a clearance position. The fall arresting axis intersects the first direction. The chain drive assembly includes a chain. The chain is connected to the carrier rack. The stacker rack has a plurality of locking holes. The locking holes are spaced apart in the vertical direction of the stacker rack. The locking holes are adapted to insert the fall arresting element located at the fall arresting position. The fall arresting element located at the fall arresting position disengages from the stacker rack.

[0019] Optionally, the fall arrest assembly further includes a fall arrest housing and a movable connector. The fall arrest housing is fixed to the rack. The movable connector is movably connected to the fall arrest housing along the vertical direction. One end of the fall arrest member forms a latch adapted to be inserted into the lock hole. The fall arrest member is linked to the movable connector. One end of the chain is connected to the movable connector to drive the rack to rise and fall via the movable connector.

[0020] Optionally, the fall arresting assembly further includes an anti-rotation member. The anti-rotation member is fixed to the fall arresting housing. The anti-rotation member is spaced apart from the fall arresting axis. The anti-rotation member is used to abut against the fall arresting member as it rotates from the avoidance position to the fall arresting position, thereby preventing the fall arresting member from continuing to rotate.

[0021] Optionally, the fall arrest assembly further includes a follower connector and a fall arrest reset member. The follower connector is connected to the lower part of the movable connector and movably connected to the end of the fall arrest member away from the latch, so that the fall arrest member is linked to the movable connector. The fall arrest reset member is disposed between at least one of the movable connector, the follower connector, and the fall arrest member and the fall arrest housing, so as to apply a force toward the fall arrest position to the fall arrest member.

[0022] A second aspect of this disclosure provides a battery swapping station. The battery swapping station includes the stacker crane described above.

[0023] According to the second aspect of this disclosure, by applying the stacker crane described above, the requirements for the machining accuracy of the mounting surface of the slide rail can be reduced, thereby reducing production costs. Attached Figure Description

[0039] The terms “center,” “parallel,” “perpendicular,” “aligned,” and “symmetrical” used in this disclosure are not necessarily precise, but may include typical engineering tolerances.

[0040] Hereinafter, a more detailed description of the specific embodiments of the stacker crane 150 and the battery swapping station 100 having therein will be provided with reference to Figures 1 to 9. These figures illustrate representative embodiments of the present disclosure and are not intended to limit the present disclosure.

[0041] Referring to Figures 1 to 8, an embodiment of this disclosure provides a stacker crane 150. The stacker crane 150 is applied to a battery swapping station 100. The stacker crane 150 includes a carrier rack 151, a stacking rack 153, a first guide assembly 154, and an adjusting connection assembly 155.

[0042] The stacking rack 153 has a first mounting surface 153a extending along a first direction D1. Here, the first direction D1 is, for example, a vertical direction DV or a substantially vertical direction DV. The vertical direction DV can be referred to as the vertical direction or the height direction. In the example where the first direction D1 is substantially vertical DV, the first direction D1 and the vertical direction DV have a small angle, such as any angle within the range of -5° to 5°. The first mounting surface 153a is typically planar, but it is not excluded that it can be made into a curved surface or other forms of surface.

[0043] A first guide assembly 154 connects the stacker rack 153 and the carrier rack 151. That is, the carrier rack 151 is mounted to the stacker rack 153 via the first guide assembly 154. This allows the carrier rack 151 to move relative to the stacker rack 153 along a first direction D1 via the first guide assembly 154. The first guide assembly 154 includes, for example, a first slide rail 154a and a first sliding portion 154b. The first slide rail 154a is fixed to a first mounting surface 153a and extends along the first direction D1. The first sliding portion 154b is slidably connected to the first slide rail 154a along the first direction D1.

[0044] An adjusting connecting assembly 155 is movably connected between the first sliding portion 154b and the rack 151, allowing the first sliding portion 154b to move relative to the rack 151 in a second direction D2. The second direction D2 is perpendicular or substantially perpendicular to the first mounting surface 153a. The second direction D2 is, for example, the longitudinal direction DL of the stacker rack 153. In the example where the second direction D2 is substantially perpendicular to the first mounting surface 153a, the angle between the second direction D2 and the first mounting surface 153a can be any angle within the range of 85° to 95°.

[0045] According to an embodiment of the stacker crane 150 of this disclosure, an adjusting connecting assembly 155 is added between the carrying rack 151 and the first sliding portion 154b to allow the carrying rack 151 to move relative to the first sliding portion 154b in the second direction D2. By adopting the above technical solution, the problem of non-coplanarity and non-parallelism of the mounting surfaces of a pair of slide rails, including the first slide rail 154a, caused by insufficient machining accuracy or assembly errors can be overcome. This also helps to reduce the machining accuracy requirements of the mounting surfaces of the slide rails, thereby reducing production costs. At the same time, it can also reduce the external force on the first sliding portion 154b, thereby increasing the lifespan of the first guide assembly 154.

[0046] Referring to Figures 1 to 3 and Figure 5, the adjustable connecting assembly 155, by way of example, includes a first connecting member 155a and a second connecting member 155b. The first connecting member 155a is fixedly connected to a first sliding portion 154b. The second connecting member 155b is fixedly connected to the rack 151. The first connecting member 155a is movably connected to the second connecting member 155b along a second direction D2. During the lifting and lowering movement of the rack 151, the first connecting member 155a and the second connecting member 155b can adaptively move relative to each other in the second direction D2 to accommodate usage scenarios where the mounting surfaces of a pair of slide rails, including the first slide rail 154a, are not coplanar or parallel.

[0047] Referring to Figures 1 to 3, 5, and 6, the second connecting member 155b further includes a guide hole 155b4 extending along the second direction D2. The first connecting member 155a is movably connected to the guide hole 155b4. Through the cooperation between the guide hole 155b4 and the first connecting member 155a, the movement of the first connecting member 155a relative to the second connecting member 155b can be guided to ensure that the first connecting member 155a moves along the second direction D2.

[0048] It is understood that the guide hole can also be provided in the first connecting member 155a. Correspondingly, the second connecting member 155b is connected to the guide hole.

[0049] Referring to Figures 5 and 6, exemplarily, the second connecting member 155b includes a guide block 155b1 and a bushing 155b3. The guide block 155b1 is fixedly connected to the rack 151. The guide block 155b1 has a mounting hole 155b2. The bushing 155b3 is at least partially embedded in the mounting hole 155b2. The bushing 155b3 has a guide hole 155b4. In this embodiment, the bushing 155b3 is connected to the first connecting member 155a, facilitating the individual replacement of the bushing 155b3 and reducing maintenance costs.

[0050] Optionally, bushing 155b3 may be an oil-free bushing. The oil-free bushing includes a tubular portion 155b5 that can pass through the mounting hole 155b2 and a first flange mounting portion 155b6 located outside the guide block 155b1. This flange mounting portion is used for bolt mounting to the guide block 155b1.

[0051] In the examples shown in Figures 5 and 6, the guide block 155b1 is provided with two mounting holes 155b2 and two bushings 155b3. Accordingly, the adjusting connection assembly 155 includes two first connecting members 155a.

[0052] Optionally, the first connecting member 155a includes a guide rod 155a1 and a second flange mounting portion 155a2. The guide rod 155a1 is for passing through the guide hole 155b4. The second flange mounting portion 155a2 is for mounting to the first sliding portion 154b by bolts.

[0053] In other examples not shown, the number of mounting holes 155b2 of the guide block 155b1, the number of bushings 155b3 corresponding to the same guide block 155b1, and the number of first connecting members 155a corresponding to a guide block 155b1 can each be three or other numbers. The number of mounting holes 155b2 of the guide block 155b1, the number of bushings 155b3 corresponding to the same guide block 155b1, and the number of first connecting members 155a corresponding to a guide block 155b1 are the same.

[0054] Referring to Figures 1 to 3, exemplarily, the stacker 153 further has a second mounting surface 153b. The second mounting surface 153b is spaced apart from the first mounting surface 153a along the width direction DW (also referred to as the third direction D3) of the stacker 153, for example, the second mounting surface 153b and the first mounting surface 153a are located on opposite sides of the rack 151 along the width direction DW of the stacker 153. The second mounting surface 153b extends along a first direction D1. The stacker crane 150 also includes a second guide assembly 156. The second guide assembly 156 includes a second slide rail 156a and a second sliding portion 156b. The second slide rail 156a is fixed to the second mounting surface 153b. The second slide rail 156a extends along the first direction D1. The second sliding portion 156b is slidably connected to the second slide rail 156a along the first direction D1. The second sliding portion 156b is fixed to the rack 151. It can be understood that the second slide rail 156a here and the first slide rail 154a mentioned above are a pair of slide rails. Since the second sliding part 156b is fixed to the rack 151, the adaptive position adjustment of the first sliding part 154b and the rack 151 by the adjusting connection assembly 155 is based on the second mounting surface 153b. Thus, under the premise that the position of the rack 151 relative to the second mounting surface 153b in the second direction D2 remains unchanged or substantially unchanged, the position of the first sliding part 154b relative to the rack 151 in the second direction D2 can be adaptively adjusted by the adjusting connection assembly 155.

[0055] It should be noted that both the first mounting surface 153a and the second mounting surface 153b extend along the first direction D1. Ideally, the first mounting surface 153a and the second mounting surface 153b are symmetrical, parallel, or coplanar (the first mounting surface 153a and the second mounting surface 153b face the same direction). However, in actual processing, the first mounting surface 153a and the second mounting surface 153b may become asymmetrical, non-parallel, or non-coplanar due to low processing accuracy or installation errors. If the first sliding part 154b in the first guide assembly 154 and the second sliding part 156b in the second guide assembly 156 are both fixedly connected to the rack 151, during the up-and-down movement of the rack 151, one of the first sliding part 154b and the second sliding part 156b will be pulled away from the slide rail or squeezed towards the slide rail in the second direction D2, causing damage to the guide assembly or affecting the normal movement of the rack 151. The technical solution disclosed herein is intended to solve the following problem: by setting the adjustment connection component 155, the first sliding part 154b has space and possibility for relative movement with the rack 151 in the second direction D2, thereby avoiding damage to the guide component, ensuring the normal movement of the rack 151, and also reducing the precision requirements for the manufacturing of the stacking rack 153 itself.

[0056] In this disclosure, the first direction D1, the second direction D2, and the third direction D3 are ideally perpendicular to each other, but due to low machining accuracy or installation errors, they are basically perpendicular to each other.

[0057] Referring again to Figures 1 to 3, the stacking rack 153 further includes two first mounting surfaces 153a. The two first mounting surfaces 153a are spaced apart along the length direction DL of the stacking rack 153. For example, along the length direction DL of the stacking rack 153, the two first mounting surfaces 153a are located at both ends of the stacking rack 153. In other words, the two first mounting surfaces 153a are located at both ends of the stacking rack 153 along the length direction DL of the stacking rack 153. Each first mounting surface 153a is provided with a first guide assembly 154 and an adjusting connection assembly 155 between it and the carrier rack 151. The stacking rack 153 also includes two second mounting surfaces 153b. The two second mounting surfaces 153b are spaced apart along the length direction DL of the stacking rack 153. For example, along the length direction DL of the stacking rack 153, the two second mounting surfaces 153b are located at both ends of the stacking rack 153. Each second mounting surface 153b is provided with a second guide assembly 156 between it and the carrier rack 151. Thus, at both ends of the stacking rack 153 along the length direction DL, each adjusting connection component 155 has a second mounting surface 153b as a reference surface, thereby ensuring the stability of the rack 151 during its movement along the vertical direction DV.

[0058] In the examples shown in Figures 1 to 3, along the width direction DW of the stacking rack 153, the two first mounting surfaces 153a are located at the same end of the stacking rack 153. Along the width direction DW of the stacking rack 153, the two second mounting surfaces 153b are located at the same end of the stacking rack 153.

[0059] Optionally, the second sliding part 156b can be fixedly connected to the rack 151 by an intermediate connector such as an angle iron.

[0060] Referring to Figures 1, 2, 7, and 8, the stacker crane 150, by way of example, further includes a fall arrest assembly 158 and a chain drive assembly 157. The fall arrest assembly 158 includes a fall arrest member 158a and a drive connection member 158k. The fall arrest member 158a is movably connected to the rack 151 between a fall arrest position and a clearance position. For example, the fall arrest member 158a is rotatably connected to the rack 151 about a fall arrest axis AX between the fall arrest position and the clearance position. The fall arrest axis AX is not parallel to a first direction D1. The fall arrest axis AX extends, for example, in a horizontal direction. For example, the fall arrest axis AX is parallel to the width direction DW of the stacker 153. The drive connection member 158k is actuated to one end of the fall arrest member 158a to apply a force to the fall arrest member 158a toward the fall arrest position. In the fall arrest position, the fall arrest member 158a contacts the stacker 153; in the clearance position, the fall arrest member 158a disengages from the stacker 153. Chain drive assembly 157 is used to transmit power between a power source and a rack 151, thereby causing the rack 151 to rise or fall. Chain drive assembly 157 includes a chain 157a. Chain 157a is connected to rack 151 via a drive connection member 158k. Stacking rack 153 has a plurality of locking holes 153c. A first direction D1 is, for example, a vertical direction DV. All locking holes 153c are spaced apart in the vertical direction DV. Locking holes 153c are adapted to accommodate a fall arresting member 158a in a fall arresting position. That is, when the fall arresting member 158a is in the fall arresting position, the end of the fall arresting member 158a away from the drive connection member 158k can be inserted into the locking hole 153c. During the process of chain 157a breaking or detaching from the rack 151 and the rack 151 falling, the anti-fall component 158a pivots from the avoidance position to the anti-fall position and inserts into one of the multiple locking holes 153c, thereby stopping the rack 151 at a certain position along the vertical direction DV, thus preventing the rack 151 from falling further. By setting the anti-fall component 158, the rack 151 can be prevented from falling during the process of chain 157a breaking or detaching from the rack 151 and the rack 151 falling, thereby protecting the rack 151 and the battery pack located on the rack 151.

[0061] Referring to Figures 7 and 8, the fall arrest assembly 158 further includes a fall arrest housing 158i. The fall arrest housing 158i is directly or indirectly fixed to the rack 151. The fall arrest member 158a is movably connected to the fall arrest housing 158i between a fall arrest position and a avoidance position, for example, the fall arrest member 158a is rotatably connected to the fall arrest housing 158i about the fall arrest axis AX between the fall arrest position and the avoidance position. The transmission connection member 158k is movably connected to the fall arrest housing 158i along a first direction D1. One end of the chain 157a is connected to the transmission connection member 158k, and the other end is connected to the fall arrest housing 158i, to drive the rack 151 to rise and fall.

[0062] The fall arrestor housing 158i has a receiving space 158i3. The transmission connection member 158k includes a movable connector 158c, a follower connector 158d, and a fall arrestor reset member 158e. The movable connector 158c is movably connected to the fall arrestor housing 158i along a first direction D1. The upper end of the movable connector 158c extends above the fall arrestor housing 158i and is connected to one end of the chain 157a. The lower end of the movable connector 158c is located in the receiving space 158i3. The follower connector 158d is located in the receiving space 158i3. The follower connector 158d is connected to the lower end of the movable connector 158c. The follower connector 158d is also movably connected to one end of the fall arrestor 158a, so that the fall arrestor 158a is linked to the movable connector 158c. A fall arrestor 158e is disposed between at least one of the movable connector 158c, the follower connector 158d, and the fall arrestor 158a and the fall arrestor housing 158i, to apply a force to the fall arrestor 158a toward the stop position. For example, the fall arrestor 158e is disposed between the follower connector 158d and the fall arrestor housing 158i. For example, the fall arrestor 158e is disposed between the follower connector 158d and the actuating plate 158m of the fall arrestor housing 158i. For example, the fall arrestor 158e is a compression spring disposed between the upper surface of the follower connector 158d and the lower surface of the actuating plate 158m.

[0063] One end of the fall arrestor 158a forms a latch 158a1 suitable for insertion into the lock hole 153c. A follower connector 158d is movably connected to the end of the fall arrestor 158a away from the latch 158a1. The fall arrestor 158a is linked to the movable connector 158c via the follower connector 158d. One end of the chain 157a is connected to the movable connector 158c to drive the fall arrestor assembly 158 to rise and fall as a whole via the movable connector 158c, thereby driving the rack 151 to rise and fall. When the chain 157a is disconnected or disengaged from the movable connector 158c, under the action of the fall arrestor reset member 158e, the transmission connecting member 158k moves relative to the fall arrestor housing 158i in a first direction D1, for example, descends. In this way, the anti-fall reset member 158e can transmit an elastic force between the movable connector 158c and the anti-fall member 158a when the chain 157a breaks or the chain 157a disengages from the movable connector 158c, so that the anti-fall member 158a can pivot from the avoidance position to the anti-fall position.

[0064] Referring to Figures 1, 2, 4, 7, and 8, optionally, the chain drive assembly 157 further includes an upper sprocket 157b and a lower sprocket 157c, with the upper sprocket 157b positioned above the lower sprocket 157c. One end of the chain 157a passes over the upper sprocket 157b and connects to the movable connector 158c. The other end of the chain 157a passes over the lower sprocket 157c and connects to the fall arrester housing 158i. The chain 157a is supported and tensioned by the upper sprocket 157b and the lower sprocket 157c. The power source of the stacker crane 150 can be connected to the upper sprocket 157b via a drive shaft to output torque to the upper sprocket 157b through the drive shaft. The upper sprocket 157b meshes with the drive chain 157a. As the upper sprocket 157b rotates in one direction, it can drive the rack 151 to rise. As the upper sprocket 157b rotates in the opposite direction, it can drive the rack 151 to move up and down. The lower sprocket 157c, as the driven wheel, can adaptively engage the transmission chain 157a during the rotation of the upper sprocket 157b, so that the chain 157a moves cyclically.

[0065] Referring to Figures 7 and 8, the fall arrest assembly 158 further includes an anti-rotation member 158b. The anti-rotation member 158b is fixed to the fall arrest housing 158i. The anti-rotation member 158b is spaced apart from the fall arrest axis AX. The anti-rotation member 158b is used to abut against the fall arrest member 158a during its rotation from the avoidance position to the stop position, thereby preventing the fall arrest member 158a from continuing to rotate. That is, the anti-rotation member 158b is used to prevent the fall arrest member 158a from continuing to rotate away from the avoidance position when it moves to the stop position, thereby limiting the fall arrest member 158a to the stop position.

[0066] Optionally, the anti-rotation component 158b can be a structure such as a limit block.

[0067] Optionally, the fall arrestor 158e can be a spring such as a compression spring, tension spring, or torsion spring. When selecting a spring for installation, factors such as the installation location must be considered.

[0068] In the examples shown in Figures 7 and 8, the fall arrestor 158a has a first shaft hole 158a2 and a second shaft hole 158a3. The fall arrestor assembly 158 also includes a first connecting shaft 158g and a second connecting shaft 158h. The first connecting shaft 158g is fixed to the end of the follower connecting member 158d away from the movable connecting member 158c. The first connecting shaft 158g passes through the first shaft hole 158a2. The second connecting shaft 158h passes through the second shaft hole 158a3 and is fixed to the fall arrestor housing 158i. The first shaft hole 158a2 is an elongated hole to allow the first connecting shaft 158g to move adaptively relative to the fall arrestor 158a to prevent jamming.

[0069] Referring again to Figures 7 and 8, the movable connector 158c passes through the through hole 158n in the action plate 158m. Optionally, the movable connector 158c includes a first chain connection portion 158c1, a rod body 158c2, and a nut 158c3 arranged sequentially from top to bottom. The first chain connection portion 158c1 is fixed to the upper end of the rod body 158c2. The first chain connection portion 158c1 and the rod body 158c2 can be constructed as a single unit. The first chain connection portion 158c1 is used to connect to the chain 157a by fasteners such as bolts. At least the lower part of the rod body 158c2 is provided with external threads. Here, the rod body 158c2 can be regarded as a screw. The nut 158c3 is threaded to the rod body 158c2. The size of the upper end of the first chain connection portion 158c1 is larger than the diameter of the through hole 158n. The outer diameter of the nut 158c3 is larger than the diameter of the through hole 158n. Therefore, the movable connector 158c is always inserted in the through hole 158n and cannot be separated from the action plate 158m.

[0070] In the examples shown in Figures 7 and 8, the end of the follower connector 158d furthest from the stop member 158a has a through hole for the rod 158c2 to pass through. The nut 158c3 is located below the follower connector 158d and is used to limit the movement of the follower connector 158d. The stop reset member 158e is a compression spring. The compression spring is located in the receiving space 158i3. The compression spring is positioned vertically DV between the upper action plate 158m of the stop housing 158i and the upper surface of the follower connector 158d. In the initial state, the compression spring has an elastic force and ensures that the follower connector 158d always abuts against the nut 158c3. The compression spring can be sleeved on the outside of the rod 158c2.

[0071] Referring again to Figures 7 and 8, optionally, the follower connector 158d has a guide hole 158d1. The fall arrest assembly 158 also includes a guide support post 158f. The guide hole 158d1 extends vertically in the direction DV. The guide support post 158f is fixed to the fall arrest housing 158i. The guide support post 158f extends vertically in the direction DV. The guide support post 158f includes a guide section 158f1 and a support section 158f2. The guide section 158f1 is located above the support section 158f2. The radial outer dimension of the guide section 158f1 is smaller than the radial outer dimension of the support section 158f2. The guide section 158f1 can extend into the guide hole 158d1. The support section 158f2, being thicker, cannot enter the guide hole 158d1. The guide section 158f1 is movably connected to the guide hole 158d1. The support section 158f2 is used to support the follower connector 158d when the fall arrestor 158a is in the fall arrest position. Through the cooperation between the guide hole 158d1 of the follower connector 158d and the guide section 158f1 of the guide support column 158f, the movement of the follower connector 158d in the vertical direction DV can be guided. By providing the support section 158f2 on the guide support column 158f, the follower connector 158d can be supported when the fall arrestor 158a is in the fall arrest position, thereby indirectly preventing the fall arrestor 158a from pivoting, and further improving the reliability and stability of preventing the rack 151 from falling.

[0072] Referring again to Figures 7 and 8, exemplarily, the receiving space 158i3 accommodates at least a portion of the fall arrester 158a, a portion of the movable connector 158c, the fall arrester resetter 158e, and the follower connector 158d. A bottom receiving hole 158i1 is provided at the bottom of the fall arrester housing 158i. The bottom receiving hole 158i1 is adapted to receive the lower end of the rod 158c2. The fall arrester assembly 158 also includes a second chain connection 158j. The second chain connection 158j is connected to the lower part of the fall arrester housing 158i and is adapted to connect the other end of the chain 157a.

[0073] Referring again to Figures 7 and 8, the stacker crane 150, by way of example, also includes a measured element 159a and a sensing element 159b. The measured element 159a is located on the upper part of the movable connector 158c. The sensing element 159b is located on the upper part of the fall arrestor housing 158i. When the fall arrestor 158a is in the avoidance position, the measured element (159a) is spaced apart from the sensing element (159b) along the first direction D1, for example, the measured element 159a is higher than the sensing element 159b in the vertical direction DV. When the fall arrestor 158a is in the stop position, the measured element 159a triggers the sensing element 159b. In application scenarios where the chain 157a is disconnected or detached, the state of the chain 157a can be detected through the cooperation of the measured element 159a and the sensing element 159b, thereby sending a detection signal to the control device of the battery swapping station as data basis for fault alarm and reminder, thereby improving the automation and intelligence level of the battery swapping station in terms of monitoring.

[0074] With chain 157a not disconnected or detached from the anti-fall assembly 158, and chain 157a tensioned while lifting the rack 151, both ends of chain 157a are connected to the upper part of movable connector 158c and the lower part of anti-fall housing 158i, respectively. Because the outer diameter of nut 158c3 is larger than the diameter of through hole 158n, transmission connecting member 158k is pulled upwards but cannot detach from actuating plate 158m, causing anti-fall reset member 158e to be compressed and tightened between follower connector 158d and actuating plate 158m, thereby causing elastic deformation of anti-fall reset member 158e (generating elastic force). Simultaneously, the end of anti-fall member 158a connected to follower connector 158d is higher than the end of anti-fall member 158a away from follower connector 158d, and locking tongue 158a1 retracts into anti-fall housing 158i, at which point anti-fall member 158a is in the avoidance position. When chain 157a is tensioned, the relative positions between movable connector 158c and anti-fall housing 158i remain constant due to the unchanged length of chain 157a. In other words, chain 157a acts as a limiting force on both, which also keeps the length of spring 158e constant. When chain 157a disconnects or detaches from anti-fall assembly 158, anti-fall assembly 158 and rack 151 fall together. During the fall of anti-fall assembly 158 and rack 151, movable connector 158c and anti-fall housing 158i lose the limiting force of chain 157a, allowing the length of spring 158e to change. When the compression spring 158e extends, the movable connector 158c and the follower connector 158d move downward relative to the fall arrest housing 158i under the elastic force of the fall arrest reset member 158e. At the same time, the follower connector 158d drives the end of the fall arrest member 158a away from the locking tongue 158a1 to pivot downward around the axis of the second connecting shaft 158h (fall arrest axis AX), while the locking tongue 158a1 moves upward, thereby moving the fall arrest member 158a towards the stop position. When the fall arrest member 158a moves to the stop position, the locking tongue 158a1 of the fall arrest member 158a extends out of the fall arrest housing 158i and is inserted into the adjacent locking hole 153c to prevent the rack 151 from falling. When the anti-falling member 158a moves to the anti-falling position, the end of the anti-falling member 158a away from the locking tongue 158a1 overlaps the upper part of the anti-rotation member 158b. The anti-rotation member 158b prevents the anti-falling member 158a from continuing to pivot in a direction away from the avoidance position, thereby limiting the anti-falling member 158a to the anti-falling position. This helps to improve the stability of the connection structure between the anti-falling member 158a and the locking hole 153c of the stacking rack 153, and thus helps to reliably keep the rack 151 in a certain position, achieving the purpose of more reliably preventing the rack 151 from falling.

[0075] Referring to Figures 1 to 4, the stacker crane 150 also includes forks 152. The forks 152 are mounted on the rack 151 and are capable of moving up and down with the rack 151. The forks 152 are used to carry battery packs, enabling the removal and placement of battery packs from and into the battery racks. The forks 152 can be bidirectional forks to accommodate applications requiring the separate handling of battery packs on two opposing battery racks and the transfer of battery packs between two battery racks.

[0076] The stacker crane 150 disclosed herein includes an adjustable connecting assembly 155 disposed between the first guide assembly 154 and the carrier rack 151. When the carrier rack 151 moves up and down in the vertical direction DV, the effects caused by insufficient parallelism of the slide rail mounting surface are absorbed by the mutual movement of the first connecting member 155a and the second connecting member 155b in the second direction D2. This significantly reduces the adverse effects of insufficient machining accuracy and assembly errors, increases the service life of the first guide assembly 154, and reduces machining costs and requirements.

[0077] Referring to Figure 9, an embodiment of this disclosure also provides a battery swapping station 100. The battery swapping station 100 includes the stacker crane 150 described above.

[0078] According to the embodiments of the present disclosure, by applying the stacker crane 150 described above, the requirements for the machining accuracy of the mounting surface of the slide rail can be reduced, thereby reducing production costs.

[0079] Referring to Figure 9, the battery swapping station 100 also includes a container 111, a lifting assembly 120, a battery swapping robot 130, a first battery rack 140, and a second battery rack 160. The external dimensions of the container 111 can be those of a standard shipping container, such as a 40-foot standard shipping container. The lifting assembly 120, battery swapping robot 130, first battery rack 140, stacker crane 150, and second battery rack 160 are all located inside the container 111. One end of the container 111 has a battery swapping channel 111e. The battery swapping channel 111e is used to accommodate vehicles to be swapped. The lifting assembly 120 is located in the battery swapping channel 111e and is used to lift and lower the vehicles. The battery swapping channel 111e, first battery rack 140, stacker crane 150, and second battery rack 160 are arranged sequentially along the length direction DL. The first battery swapping robot 130 can move along the length direction DL between the battery swapping channel 111e and the first battery rack 140. When the battery swapping robot 130 is located in the battery swapping channel 111e, it can remove the battery pack 10 from the vehicle or install the battery pack 10 into the vehicle. When the battery swapping robot 130 is located in the first battery rack 140, it can remove the battery pack 10 from the first battery rack 140 or place the battery pack 10 in the first battery rack 140. The first battery rack 140 has a buffer layer and a first charging layer. The first charging layer is located above the buffer layer. The buffer layer is used to store the battery pack 10 transferred by the battery swapping robot 130, or to buffer the battery pack transferred by the stacker crane 150 from the first charging layer or the second battery rack 160. The first charging layer is adapted to store the battery pack 10 and charge the battery pack 10. The second battery rack 160 includes a second charging layer for storing the battery pack 10 and charging the battery pack 10.

[0080] Referring to Figure 9, exemplarily, to meet monitoring needs, the battery swapping station 100 also includes a camera 115 suitable for acquiring image information. The camera 115 is typically installed outside the battery swapping station 100 to acquire images, videos, and other image information of the surrounding environment and send them to the monitoring equipment or host computer of the battery swapping station 100, so that monitoring personnel can intuitively understand the external situation of the battery swapping station 100. The external situation of the battery swapping station 100 includes vehicle entry and exit, rain, snow, and other conditions.

[0081] The stacker crane 150 and the battery swapping station 100 having the present disclosure reduce the adverse effects of processing, increase the service time of structures such as the first guide component 154 and even the second guide component 156, reduce processing costs, and lower the processing accuracy requirements.
