Description

Technical Field

[0001] This application relates to the field of logistics technology, and more specifically, to a lifting assembly and a shuttle. Background Technology

[0002] Currently, shuttles typically include two-way and four-way shuttles. Two-way shuttles can move linearly back and forth on a single track, such as moving in the forward and backward directions. Four-way shuttles can move freely on crisscrossing tracks, such as moving in the forward, backward, left, and right directions. Due to the limitations of the track structure, when the shuttle's top plate lifts the pallet, the edge of the top plate abuts against the pallet's weakest point. This makes the pallet prone to shifting or deforming during shuttle operation, requiring frequent pallet position adjustments, thus increasing the number of corrections. The increased number of corrections within the predetermined operating time inevitably reduces the number of repositioning operations. Furthermore, due to the variety of pallet types, when the shuttle's top plate uses a split design, the pallet experiences uneven stress, generating horizontal inward or outward forces along the width of the shuttle. This leads to uneven lifting, increased noise, and even damage to pallets made of softer materials. Utility Model Content

[0003] In order to at least partially solve the problems existing in the prior art, according to one aspect of this application, a lifting component is provided, the technical solution of which is as follows.

[0004] The lifting assembly includes a lifting plate for lifting a cargo pallet, the cargo pallet having two sets of edge support columns spaced apart along a first direction, the lifting plate having two outer sides arranged along the first direction, the distance between the two outer sides being greater than the distance between the two sets of edge support columns, and when the lifting assembly is in the lifting state, the lifting plate at least partially abuts against the edge support columns.

[0005] The lifting assembly of this application has a lifting plate with two outer sides arranged along a first direction. The distance between the two outer sides is greater than the spacing between the two sets of edge support columns. When the lifting assembly is applied to a shuttle, and the lifting assembly is in the lifting state, the lifting plate at least partially abuts against the edge support columns, making the load on the pallet more evenly stressed, the lifting process smooth, and the noise less. Therefore, the lifting assembly can be used to lift pallets of different types and materials. Moreover, the load on the pallet is not easily shifted or deformed during the operation of the shuttle, so there is no need to frequently adjust the position of the load on the pallet, thereby reducing the number of corrections. Within the predetermined operating time, the reduction in the number of corrections will inevitably increase the number of times the pallet is emptied, improve the utilization rate of the automated warehouse, and extend the life of the load on the pallet.

[0006] For example, the lifting plate includes at least two plates spaced apart along a first direction, wherein the outer edges of the two plates located on both sides in the first direction are the outer edges.

[0007] For example, each plate includes a plate body and an extension body, the extension body extending outward from the edge of the plate body along the width direction of the plate body, and the side of the extension body away from the plate body is the outer side.

[0008] For example, the lifting plate includes a plate body and an extension body, the extension body extending outward from the edge of the plate body along the width direction of the plate body, and the side of the extension body away from the plate body is the outer side.

[0009] For example, a first guide post protrudes from the lower surface of the plate body.

[0010] For example, the first guide post has at least two posts, and the at least two first guide posts are divided into at least two guide post groups in the length direction of the plate body.

[0011] For example, a second guide post is provided on the epitaxial body between two adjacent guide post groups, and the second guide post protrudes from the lower surface of the epitaxial body.

[0012] For example, the lower surface of the epitaxial body has a second guide post protruding from it.

[0013] According to another aspect of this application, a shuttle vehicle is provided, including a vehicle body and a lifting assembly as described above, wherein a lifting plate is connected to the vehicle body and is movable relative to the vehicle body. Since the lifting assembly as described above has the aforementioned beneficial effects, the shuttle vehicle including the lifting assembly as described above also has the aforementioned beneficial effects, which will not be elaborated further here.

[0014] For example, a first guide post and a second guide post protrude from the lower surface of the lifting plate, the second guide post being closer to the outer side than the first guide post, and a first guide hole for the first guide post to pass through and a second guide hole for the second guide post to pass through are provided on the vehicle body.

This utility model description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0026] In the following description, numerous details are provided to enable a thorough understanding of this application. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the application, and that the application can be implemented without one or more of these details. Furthermore, to avoid confusion with this application, some technical features well-known in the art have not been described in detail.

[0027] To fully understand the embodiments of this application, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this application is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this application are described in detail below; however, other embodiments may be available in addition to these detailed descriptions.

[0028] Embodiments of this application provide a lifting assembly. This lifting assembly can be applied to a shuttle vehicle. A detailed description of a lifting assembly according to an embodiment of this application will follow with reference to the accompanying drawings.

[0029] See also Figures 1 to 6The lifting assembly 10 may include a lifting plate 100 for lifting the cargo pallet 20. It should be noted that the cargo pallet 20 ensures the shuttle can stably carry and transport goods, reducing handling problems caused by inconsistent shapes or sizes of goods. The cargo pallet 20 can be a wooden pallet, allowing for recycling. The cargo pallet 20 can also be a plastic pallet, which enhances its strength. Of course, the cargo pallet 20 can also be a paper pallet, a steel pallet, etc. The cargo pallet 20 may have a first direction (e.g., Figure 2 and Figure 5 Two sets of edge support columns 210 are spaced apart (in the XX direction shown). The first direction can be the width direction of the pallet 20. Multiple support columns, such as two, three, or four, can also be provided between the two sets of edge support columns 210 to more stably support the goods. Each set of edge support columns 210 can have multiple columns, such as two, three, or four. In one embodiment of this application, each set of edge support columns 210 can have three columns, and three support columns can be provided between the two sets of edge support columns 210, with the three support columns extending along the length direction of the pallet 20 (e.g., in the XX direction shown). Figure 2 and Figure 5 The lifting plate 100 is arranged sequentially at intervals (in the YY direction shown). The lifting plate 100 may have two outer edges 101 arranged along a first direction. Since the lifting plate 100 is used to lift the cargo tray 20, the length of the cargo tray 20 corresponds to the length of the lifting plate 100, and the width of the cargo tray 20 corresponds to the width of the lifting plate 100. Therefore, the width direction of the cargo tray 20 can be the width direction of the lifting plate 100, and the first direction can be the width direction of the lifting plate 100. The distance S1 between the two outer edges 101 can be greater than the distance S2 between the two sets of edge support columns 210. Understandably, the distance S2 between the two sets of edge support columns 210 is the distance between the inner edges 211 of the two sets of edge support columns 210 (i.e., the sides of the two sets of edge support columns 210 that are close to each other). When the lifting assembly 10 is in the lifting state, the lifting plate 100 can at least partially abut against the edge support columns 210. In other words, when the lifting assembly 10 is in the lifting state, the edge support column 210 is at least partially located on the lifting plate 100. It should be noted that the lifting state can be the state in which the lifting plate 100 bears the weight of the cargo tray 20. Specifically, the lifting state can refer to any moment during the process of the lifting plate 100 driving the cargo tray 20 to rise or fall; the lifting state can also refer to the static holding state after reaching the target height.

[0030] The lifting assembly 10 of this application has a lifting plate 100 with two outer sides 101 arranged along a first direction. The distance S1 between the two outer sides 101 is greater than the distance S2 between the two sets of edge support columns 210. When the lifting assembly 10 is applied to a shuttle car and is in the lifting state, the lifting plate 100 at least partially abuts against the edge support columns 210, so that the load pallet 20 is subjected to more uniform force, the lifting process is smooth and the noise is low. Therefore, the lifting assembly 10 can be used to lift load pallets 20 of different types and materials. Moreover, during the operation of the shuttle car, the load pallet 20 is not easy to shift or deform. Therefore, it is not necessary to frequently adjust the position of the load pallet 20, thereby reducing the number of corrections. Within the predetermined operating time, the reduction of the number of corrections will inevitably increase the number of reloadings, improve the utilization rate of the automated warehouse, and extend the life of the load pallet 20.

[0031] See also Figures 1 to 3 The lifting plate 100 may include at least two plates 110 spaced apart along a first direction. In the first direction, the outer edges of the two plates 110 located on either side may be outer edges 101. The number of plates 110 may be two, three, or four, etc. In one embodiment of this application, the lifting plate 100 may include two plates 110 spaced apart along a first direction, ensuring that the two plates 110 can be used to lift the cargo tray 20, and reducing production costs. Thus, on the one hand, the outer edges of the two plates 110 on both sides can be the outer edges 101. When the lifting assembly 10 is applied to the shuttle car and is in the lifting state, at least part of the two plates 110 on both sides abuts against the edge support column 210, making the load-bearing pallet 20 more evenly stressed, the lifting process smooth and with less noise. Therefore, the lifting assembly 10 can be used to lift load-bearing pallets 20 of different types and materials. Moreover, during the operation of the shuttle car, the load-bearing pallet 20 is not easy to shift or deform. Therefore, it is not necessary to frequently adjust the position of the load-bearing pallet 20, thereby reducing the number of corrections. Within the predetermined operating time, the reduction in the number of corrections will inevitably increase the number of times the warehouse is emptied, improve the utilization rate of the automated warehouse, and extend the life of the load-bearing pallet 20. On the other hand, the multiple plates 110 have a simple structure and are easy to disassemble. When a certain plate 110 needs maintenance, it can be disassembled individually, which facilitates maintenance.

[0032] See also Figures 1 to 4 Each plate 110 may include a plate body 120 and an extension body 130. The extension body 130 may extend from the edge of the plate body 120 along the width direction of the plate body 120 (e.g., ...). Figure 2Extending outward in the XX direction shown. The side of the extension 130 away from the plate body 120 can be the outer edge 101. It should be noted that when the lifting plate 100 includes no less than two plates 110, since in the first direction, the outer edges of the two plates 110 on both sides can be the outer edges 101, the plates 110 on both sides include the plate body 120 and the extension 130 extending outward from the edge of the plate body 120 along the width direction of the plate body 120. The side of the extension 130 away from the plate body 120 can be the outer edge 101, while the plate 110 between the two plates 110 can include the plate body 120 to save costs. When the lifting plate 100 includes two plates 110, the outer edges of the two plates 110 can be outer edges 101. The two plates 110 respectively include a plate body 120 and an extension body 130 extending outward from the edge of the plate body 120 along the width direction of the plate body 120. The side of the extension body 130 away from the plate body 120 can be the outer edge 101. Thus, on the one hand, the side of the extension body 130 away from the plate body 120 is the outer edge 101. When the lifting assembly 10 is applied to the shuttle car and is in the lifting state, at least a part of the extension body 130 abuts against the edge support column 210, making the load-bearing pallet 20 more evenly stressed, the lifting process smooth and less noisy. Therefore, the lifting assembly 10 can be used to lift load-bearing pallets 20 of different types and materials. Moreover, during the operation of the shuttle car, the load-bearing pallet 20 is not easy to shift or deform. Therefore, it is not necessary to frequently adjust the position of the load-bearing pallet 20, thereby reducing the number of corrections. Within the predetermined operating time, the reduction in the number of corrections will inevitably increase the number of times the warehouse is emptied, improve the utilization rate of the automated warehouse, and extend the life of the load-bearing pallet 20. On the other hand, the extension body 130 extends outward from the edge of the plate body 120 along the width direction of the plate body 120. The structure is simple and easy to process and manufacture.

[0033] See also Figure 5 and Figure 6 The lifting plate 100 may include a plate body 120 and an extension body 130. The extension body 130 may extend from the edge of the plate body 120 along the width direction of the plate body 120 (e.g., Figure 5Extending outward in the XX direction shown. The side of the extension 130 away from the plate body 120 can be the outer edge 101. Understandably, the lifting plate 100 can be constructed as a single plate structure, and the extension 130 can extend outward from both edges of the plate body 120 in the width direction. Thus, on the one hand, the side of the extension body 130 away from the plate body 120 can be the outer side 101. When the lifting assembly 10 is applied to the shuttle car and is in the lifting state, at least a part of the extension body 130 abuts against the edge support column 210, so that the load pallet 20 is subjected to uniform force, which can ensure the stability of the load pallet 20 during the operation of the shuttle car. Therefore, the lifting assembly 10 can be used to lift load pallets 20 of different types and materials. Moreover, during the operation of the shuttle car, the load pallet 20 is not easy to shift or deform. Therefore, it is not necessary to frequently adjust the position of the load pallet 20, thereby reducing the number of corrections. Within the predetermined operating time, the reduction of the number of corrections will inevitably increase the number of reloadings, improve the utilization rate of the automated warehouse, and extend the life of the load pallet 20. On the other hand, the lifting plate 100 is constructed as a whole plate structure, which can enhance the load-bearing capacity and deformation resistance of the lifting plate 100.

[0034] In some embodiments, when the lifting assembly 10 is in the lifting state, a portion of the edge support column 210 may be located on the extension body 130. For example, a portion of the extension body 130 may abut against a portion of the edge support column 210, and the entire extension body 130 may abut against a portion of the edge support column 210. It should be noted that this embodiment is applicable to cases where the lifting plate 100 is constructed as a single plate structure or the lifting plate 100 includes at least two plates 110. In this way, when the lifting assembly 10 is applied to the shuttle, the load pallet 20 is subjected to more uniform force, the lifting process is smooth, and the noise is less. Thus, the lifting assembly 10 can be used to lift load pallets 20 of different types and materials. Moreover, during the operation of the shuttle, the load pallet 20 is less likely to shift or deform. Therefore, it is not necessary to frequently adjust the position of the load pallet 20, thereby reducing the number of corrections. Within a predetermined operating time, the reduction in the number of corrections will inevitably increase the number of reloading operations, improve the utilization rate of the automated warehouse, and extend the life of the load pallet 20.

[0035] In some embodiments, when the lifting assembly 10 is in the lifting state, the edge support column 210 can be completely located on the extension body 130. For example, a portion of the extension body 130 can abut against the entire edge support column 210, and the entire extension body 130 can abut against the entire edge support column 210. It should be noted that this embodiment is applicable to cases where the lifting plate 100 is constructed as a single plate structure or the lifting plate 100 includes at least two plates 110. In this way, when the lifting assembly 10 is applied to the shuttle, the load pallet 20 is subjected to more even force, the lifting process is smoother, and the noise is lower. Thus, the lifting assembly 10 can be used to lift load pallets 20 of different types and materials. Moreover, during the operation of the shuttle, the load pallet 20 is less likely to shift or deform. Therefore, it is not necessary to frequently adjust the position of the load pallet 20, thereby further reducing the number of corrections. Within a predetermined operating time, the reduction in the number of corrections will inevitably increase the number of reloading operations, improve the utilization rate of the automated warehouse, and extend the life of the load pallet 20. Of course, the contact relationship between the edge load-bearing column 210 and the extension body 130 can be any suitable manner, as long as the contact relationship between the extension body 130 and the edge load-bearing column 210 is guaranteed.

[0036] In some embodiments, the plate body 120 and the extension body 130 can be an integral structure, that is, the extension body 130 can extend outward from the edge of the plate body 120 along the width direction of the plate body 120, which can improve the stability of the lifting plate 100. The plate body 120 and the extension body 130 can also be a separate structure, and the plate body 120 and the extension body 130 can be connected by means of snap-fit ​​connection, screw connection, etc., which facilitates the repair or replacement of damaged parts and reduces maintenance costs.

[0037] In some embodiments, in conjunction with reference Figure 1 and Figure 4 The thickness H1 of the epitaxial body 130 can be less than the thickness H2 of the plate body 120. In this way, when the lifting assembly 10 is applied to the shuttle, interference of the epitaxial body 130 with the shuttle body or the track on which the shuttle runs is avoided.

[0038] See again Figures 1 to 6 The lower surface of the plate body 120 may have a protruding first guide post 140. In this way, when the lifting assembly 10 is applied to the shuttle, the first guide post 140 can play a limiting and guiding role, reducing the lateral swaying of the lifting plate 100 during the lifting process, thereby ensuring the stability of the shuttle's lifting and lowering action.

[0039] See also Figures 4 to 6The plate body 120 may have a first surface 121 and a second surface 122. The first surface 121 and the second surface 122 may be arranged opposite to each other. When the lifting assembly 10 is in the lifting state, the second surface 122 may be further away from the loading tray 20 than the first surface 121. The second surface 122 may be the lower surface of the plate body 120, and the first guide post 140 may protrude from the second surface 122. Thus, on the one hand, when the lifting assembly 10 is in the lifting state, the second surface 122 is further away from the loading tray 20 than the first surface 121, and the first guide post 140 is located on the second surface 122. When the lifting assembly 10 is applied to the shuttle, the first guide post 140 can play a limiting and guiding role, reducing the lateral swaying of the lifting plate 100 during the lifting process, thereby ensuring the stability of the shuttle's lifting action; on the other hand, the first guide post 140 protrudes from the second surface 122, resulting in a simple structure and low cost. In some embodiments, the second surface 122 of the plate body 120 may have a plurality of reinforcing ribs protruding, thereby further strengthening the plate body 120.

[0040] In some embodiments, when the lifting plate 100 is constructed as a single plate structure, the first guide post 140 can be one, two, or more. When there is only one first guide post 140, it can be located in the middle of the plate body 120. This ensures smooth guidance during the lifting process. Of course, the number and position of the first guide posts 140 can be any suitable scheme, as long as the first guide post 140 can play a limiting and guiding role.

[0041] In some embodiments, when the lifting plate 100 includes at least two plates 110, there can be multiple first guide posts 140. The number of first guide posts 140 can be N times the number of plates 110 (N≥1, and N is a natural number). This ensures smooth guidance during the lifting process. Of course, the number and position of the first guide posts 140 can be any suitable scheme, as long as the first guide posts 140 can play a limiting and guiding role.

[0042] In some embodiments, the location of the first guide post 140 can be related to the shape of the plate body 120. The shape of the plate body 120 can be square, hexagonal, etc. The first guide post 140 can be located at the edge of the plate body 120. For example, when the plate body 120 is square, there can be two first guide posts 140, which can be spaced apart on two sides of the plate body 120 along the length direction, and also spaced apart on two sides of the plate body 120 along the width direction. When the plate body 120 is square, there can be four first guide posts 140, which can be spaced apart on two sides of the plate body 120 along the length direction, and also spaced apart on two sides of the plate body 120 along the width direction. The first guide post 140 can also be located at the corner of the plate body 120. For example, when the shape of the plate body 120 is square, there can be four first guide posts 140, which are respectively arranged at the corners of the square plate body 120. It should be noted that this arrangement of the first guide posts 140 is applicable when the lifting plate 100 is constructed as a single plate structure or when the lifting plate 100 includes at least two plate bodies 110. Specifically, when the lifting plate 100 includes at least two plate bodies 110, the first guide posts 140 are arranged at the corners of each plate body 120. In this way, the first guide posts 140 can provide some support and also serve as a limiting and guiding function, reducing lateral swaying of the lifting plate 100 during the lifting process. Of course, the number and arrangement of the first guide posts 140 can be any suitable scheme, as long as the first guide posts 140 can effectively perform their limiting and guiding function.

[0043] In some embodiments, the first guide post 140 and the plate body 120 can be an integral structure, that is, the first guide post 140 protrudes from the second surface 122 of the plate body 120, which can improve the stability of the lifting assembly 10. The first guide post 140 and the plate body 120 can also be a separate structure, and the first guide post 140 and the plate body 120 can be connected by means of snap-fit ​​connection, screw connection, etc., which facilitates the repair or replacement of damaged parts and reduces maintenance costs.

[0044] For example, the first guide post 140 may have at least two, and the at least two first guide posts 140 are in the length direction of the plate body 120 (e.g., Figure 2 and Figure 5 The lifting plate 100 can be divided into at least two guide column groups along the YY direction (as shown). In this way, the at least two guide column groups can provide a certain degree of support and limiting guidance, reducing the lateral swaying of the lifting plate 100 during the lifting process.

[0045] For example, a second guide post 150 may be provided on the extension body 130 between two adjacent guide post groups, and the second guide post 150 protrudes from the lower surface of the extension body 130. The number of second guide posts 150 can be one, two, or more. The number and arrangement of the second guide posts 150 can be any suitable scheme, as long as the second guide posts 150 can play a limiting and guiding role. Thus, based on the first guide post 140 on the plate body 120, a second guide post 150 is added on the extension body 130. When the lifting assembly 10 is applied to the shuttle, the plate body 120 is supported and limited by at least two guide post groups. Since the extension body 130 extends outward from the edge of the plate body 120 along the width direction of the plate body 120, the cargo tray 20 is prone to uneven force during the lifting process. By setting the second guide post 150 on the extension body 130, the lifting assembly 10 is less likely to be unbalanced when it is in the lifting state, avoiding the lifting plate 100 being subjected to unbalanced load, which would cause friction and wear of the guide post groups. This further reduces the lateral swaying of the lifting plate 100 during the lifting process, ensuring a smooth lifting process with less noise, and further ensuring the stability of the shuttle's lifting action.

[0046] In one embodiment of this application, see again with reference to Figures 1 to 3When the lifting plate 100 includes two plates 110, each plate body 120 may have four first guide posts 140, which can be divided into two guide post groups along the length of the plate body 120. Each plate body 120 may be square in shape, and the lines connecting the four first guide posts 140 on the plate body 120 may form a square similar to the plate body 120. Each plate body 120 corresponds to an extension body 130, and each extension body 130 has two second guide posts 150 positioned between the two guide post groups near the outer edge 101. Alternatively, each plate body 120's corresponding extension body 130 may also have one second guide post 150 positioned between the two guide post groups near the outer edge 101, or only one plate body 120's corresponding extension body 130 may have one second guide post 150 positioned between the two guide post groups near the outer edge 101. In some embodiments, to save costs, one of the first guide posts 140 near the second guide post 150 in each guide post group can be omitted. The length and thickness of the first guide post 140 and the second guide post 150 are not specifically limited here, as long as the first guide post 140 and the second guide post 150 can play a supporting and limiting guiding role. Thus, based on the first guide post 140 set on each plate body 120, two second guide posts 150 are added on the corresponding extension body 130. When the lifting assembly 10 is applied to the shuttle car, the two guide post groups and the two second guide posts 150 support and limit the guiding function of the lifting plate 100, so that the lifting assembly 10 is not prone to uneven load when it is in the lifting state, and avoids the lifting plate 100 being subjected to uneven load, which would cause the first guide post 140 to rub and wear. This further reduces the lateral sway of the lifting plate 100 during the lifting process, ensures a smooth lifting process with less noise, and further ensures the stability of the shuttle car's lifting action.

[0047] In one embodiment of this application, see again with reference to Figure 5 and Figure 6When the lifting plate 100 is constructed as a single plate structure, the plate body 120 may have four first guide posts 140, which can be divided into two guide post groups along the length of the plate body 120. The plate body 120 may be square in shape, and the lines connecting the four first guide posts 140 on the plate body 120 may form a square similar to the plate body 120. The plate body 120 corresponds to two extension bodies 130, and each extension body 130 has two second guide posts 150 disposed between the two guide post groups near the outer edge 101. Of course, each extension body 130 may also have one second guide post 150 disposed between the two guide post groups near the outer edge 101, or only one extension body 130 may have one second guide post 150 disposed between the two guide post groups near the outer edge 101. In some embodiments, to save costs, one first guide post 140 near the second guide post 150 in each guide post group may be omitted. The length and thickness of the first guide post 140 and the second guide post 150 are not specifically limited here, as long as they can provide support and limit guidance. Thus, based on the first guide post 140 on the plate body 120, two second guide posts 150 are added to each extension body 130. When the lifting assembly 10 is applied to the shuttle, the two guide post groups and four second guide posts 150 provide support and limit guidance for the lifting plate 100. This prevents uneven loading when the lifting assembly 10 is in the lifting state, avoiding uneven loading on the lifting plate 100, which could cause friction and wear on the first guide post 140. This further reduces lateral swaying of the lifting plate 100 during lifting, ensuring a smooth lifting process with low noise, and ultimately ensuring the stability of the shuttle's lifting action. Of course, the number and position of the first guide post 140 and the second guide post 150 can be any suitable scheme, as long as the first guide post 140 and the second guide post 150 can play a limiting and guiding role.

[0048] See again Figures 1 to 6 The lower surface of the extension body 130 has a protruding second guide post 150. Thus, when the lifting assembly 10 is applied to the shuttle, the second guide post 150 can play a limiting and guiding role, reducing the lateral swaying of the lifting plate 100 during the lifting process, thereby ensuring the stability of the shuttle's lifting and lowering operation.

[0049] See again Figures 4 to 6The extension body 130 may have a third surface 131 and a fourth surface 132. The third surface 131 and the fourth surface 132 may be arranged opposite to each other. When the lifting assembly 10 is in the lifting state, the fourth surface 132 may be further away from the loading tray 20 than the third surface 131. The third surface 131 may abut against at least a portion of the edge support column 210. The fourth surface 132 may be the lower surface of the extension body 130, and the second guide column 150 may protrude from the fourth surface 132. Thus, on the one hand, when the lifting assembly 10 is in the lifting state, the fourth surface 132 can be further away from the cargo tray 20 than the third surface 131. The second guide post 150 protrudes from the fourth surface 132. When the lifting assembly 10 is applied to the shuttle, the second guide post 150 can play a limiting and guiding role, reducing the lateral swaying of the lifting plate 100 during the lifting process, thereby ensuring the stability of the shuttle's lifting action. Furthermore, the structure is simple and the cost is low. On the other hand, the third surface 131 can be connected to the edge load-bearing column 210... The force is at least partially offset, resulting in a more even distribution of force on the pallet 20, a smooth lifting process with less noise, and thus the lifting component 10 can be used to lift pallets 20 of different types and materials. Moreover, the pallet 20 is less likely to shift or deform during the operation of the shuttle, so there is no need to frequently adjust the position of the pallet 20, thereby reducing the number of corrections. Within the predetermined operating time, the reduction in the number of corrections will inevitably increase the number of times the warehouse is emptied, improve the utilization rate of the automated warehouse, and extend the life of the pallet 20.

[0050] In some embodiments, when the lifting plate 100 is constructed as a single plate structure, the second guide post 150 can be one, two, or more. When there is only one second guide post 150, the lifting plate 100 can be supported by components such as the lifting mechanism. In this case, the second guide post 150 can be disposed on either of the two extension bodies 130. This reduces lateral swaying of the lifting plate 100 during the lifting process. Of course, the number and placement of the second guide posts 150 can be any suitable scheme, as long as the second guide posts 150 can play a limiting and guiding role.

[0051] In some embodiments, when the lifting plate 100 includes at least two plates 110, the lifting plate 100 can be supported by components such as a lifting mechanism. There can be multiple second guide posts 150, and the number of second guide posts 150 can be N times the number of extension bodies 130 (N≥1, and N is a natural number). This reduces lateral swaying of the lifting plate 100 during the lifting process. Of course, the number and position of the second guide posts 150 can be any suitable scheme, as long as the second guide posts 150 can play a limiting and guiding role.

[0052] In some embodiments, when the lifting plate 100 is configured as a single plate structure, the location of the second guide post 150 can be related to the shape of the lifting plate 100. The shape of the lifting plate 100 can be square, hexagonal, etc. The second guide post 150 can be located at the edge of the lifting plate 100, that is, the second guide post 150 can be located on the extension body 130 near the outer side 101. For example, when the lifting plate 100 is square, the lifting plate 100 has two extension bodies 130, and there can be two second guide posts 150. The two second guide posts 150 can be spaced apart on the two outer sides 101 of the lifting plate 100 along the width direction, with one second guide post 150 located near the outer side 101 of each extension body 130. The second guide post 150 can also be located at the corner of the lifting plate 100. For example, when the lifting plate 100 is square, it has two extension bodies 130, and four second guide posts 150 are provided. These four second guide posts 150 are respectively positioned at the corners of the square lifting plate 100, where each corner is formed by the corner of one of the two extension bodies 130. In this way, the second guide posts 150 provide support and also act as guides, reducing lateral swaying of the lifting plate 100 during lifting. Of course, the number and placement of the second guide posts 150 can be any suitable scheme, as long as they effectively provide guidance.

[0053] In some embodiments, the second guide post 150 and the extension body 130 can be an integral structure, that is, the second guide post 150 protrudes from the fourth surface 132 of the extension body 130, which can improve the stability of the lifting assembly 10. The second guide post 150 and the extension body 130 can also be a separate structure, and the second guide post 150 and the extension body 130 can be connected by means of snap-fit ​​connection, screw connection, etc., which facilitates the repair or replacement of damaged parts and reduces maintenance costs.

[0054] According to another aspect of this application, a shuttle vehicle is provided. The shuttle vehicle may include a four-way shuttle vehicle or a two-way shuttle vehicle, etc. The shuttle vehicle may include a vehicle body and a lifting assembly 10 as described above, with a lifting plate 100 connected to the vehicle body and movable relative to the vehicle body. Specifically, the vehicle body may have a lifting structure, and the lifting plate 100 can rise along with the lifting structure to realize the lifting action of the cargo pallet 20 and the goods in the cargo pallet 20; when descending, the lifting plate 100 can rely on its own weight or the weight of the cargo pallet 20 and the goods in the cargo pallet 20 to fall along with the lifting structure. Since the lifting assembly 10 described above has the above-mentioned beneficial effects, the shuttle vehicle including the lifting assembly 10 described above also has the above-mentioned beneficial effects, which will not be described in detail here.

[0055] For example, a first guide post 140 and a second guide post 150 protrude from the lower surface of the lifting plate 100. The second guide post 150 is closer to the outer edge 101 than the first guide post 140. The vehicle body is provided with a first guide hole for the first guide post 140 to pass through and a second guide hole for the second guide post 150 to pass through. In some embodiments, a first sleeve and a second sleeve may be provided on the vehicle body. The first guide hole may be provided on the first sleeve, and the second guide hole may be provided on the second sleeve. The first guide post 140 may be slidably disposed within the first sleeve through the first guide hole, and the second guide post 150 may be slidably disposed within the second sleeve through the second guide hole. In this way, through the cooperation of the various guide posts and the various guide holes, the shuttle can smoothly perform rising or falling movements.
