Description

Technical Field

[0001] This invention relates to the field of warehousing and transportation equipment technology, specifically to an unmanned warehouse stacking vehicle. Background Technology

[0002] Stacker cranes are specialized cranes used in warehousing and logistics, widely applied in various logistics centers, warehouses, and distribution centers. Their main function is to automate the storage, retrieval, and sorting of goods, significantly improving warehouse handling capacity and storage density. Through automated operation, stacker cranes reduce manual intervention, enhance overall logistics efficiency, and lower operating costs. As the primary handling equipment in automated warehouses, stacker cranes efficiently and accurately complete goods storage and retrieval tasks, ensuring smooth and reliable warehouse operations. Their advanced technology and intelligent control systems make stacker cranes indispensable in modern logistics systems, greatly promoting the modernization of warehouse management.

[0003] When existing stacker cranes are in operation, if the goods are stacked too high and the speed is too fast during movement, some soft goods on the stacker crane may become unstable, causing them to roll and tilt, resulting in the goods tipping over. At the same time, different goods have different heights, requiring stacker cranes of different specifications for transportation, which reduces the efficiency of transportation and stacking.

[0004] In view of the above, in order to overcome the above technical problems, the present invention designs an unmanned warehouse stacking vehicle, which solves the above technical problems.

[0005] Therefore, the present invention provides an unmanned warehouse stacking vehicle to solve the above problems. Summary of the Invention

[0006] The technical problem to be solved by the present invention is that when existing stacker cranes are in operation, if the goods are stacked too high and the speed is too fast during the movement, some soft goods on the stacker crane will become unstable, resulting in rolling and tilting, causing the goods to tip over. At the same time, different goods have different heights, requiring stacker cranes of different specifications for transportation, which reduces the efficiency of transportation and stacking.

[0007] This invention provides the following technical solution: a warehouse stacking unmanned vehicle, comprising: a vehicle body and support columns; two support columns are vertically installed at the front end of the vehicle body; it also includes a lifting mechanism and a carrying mechanism; the lifting mechanism is movably installed on the front side of the support columns, and multiple carrying mechanisms are respectively installed on the rear side of the support columns, with the carrying mechanisms located above the vehicle body; the lifting mechanism drives the forks to enter the bottom of the goods through a moving motor, and then drives the forks to move upward through the lifting motor, lifting the goods and placing them on the carrying plate on the carrying mechanism; the goods move downward by their own gravity, causing the carrying plate to move downward, driving the clamping plates on both sides of the carrying plate to move towards each other and clamping and fixing the goods.

[0008] The vehicle body is the core structure of the autonomous vehicle, with two vertical support columns mounted at the front. These columns not only provide support but also serve as the mounting base for the lifting and load-bearing mechanisms. The support columns are designed to be robust and stable, capable of withstanding the weight and pressure generated during cargo stacking, ensuring the stability of the entire system during operation.

[0009] Preferably, the lifting mechanism includes a housing, a moving motor, a lifting motor, forks, a first fixed block, a fixed seat, a first rotating shaft, and a second rotating shaft. The moving motor is mounted at one end of the housing, and the lifting motor is mounted at the other end. Two parallel forks are movably mounted on the top of the housing. First fixed blocks are mounted at both ends of the housing near the support column. A fixed seat is installed inside the housing. A first rotating shaft and a second rotating shaft are rotatably mounted on the fixed seat, and the first and second rotating shafts are parallel to each other. The first rotating shaft is connected to the lifting motor, and the second rotating shaft is connected to the moving motor.

[0010] The housing forms the main frame of the lifting mechanism, providing a foundation for the installation and support of other components. A movement motor is mounted at one end of the housing, and a lifting motor at the other. This arrangement of two motors allows the lifting mechanism to simultaneously perform horizontal movement and vertical lifting. Two parallel forks are movably mounted on the top of the housing. These forks are the components that directly contact the goods, extending to the bottom and lifting them. The housing is designed to be both robust and lightweight, ensuring structural stability while reducing overall weight and improving the operational efficiency of the autonomous vehicle.

[0011] Preferably, the bottom of each of the two forks is provided with a first fixed tooth, the two ends of the first rotating shaft are provided with a first gear, and the second rotating shaft is provided with a second gear, and the second gear meshes with the first fixed tooth.

[0012] The first rotating shaft is used to drive the first gear to rotate and drive the entire lifting mechanism to move up and down, while the second rotating shaft is used to drive the second gear to rotate and drive the fork to move horizontally, thereby placing goods on the carrying mechanism and removing goods from the carrying mechanism and placing them into the shelf.

[0013] Preferably, the fixed base is provided with a first shaft hole and a second shaft hole horizontally, and the first shaft hole cooperates with the first rotating shaft, and the second shaft hole cooperates with the second rotating shaft.

[0014] The first and second shaft holes serve to fix the first and second rotating shafts, and ensure the lifting and lowering of the lifting mechanism, as well as the horizontal movement of the fork.

[0015] Preferably, the bearing mechanism includes a bearing shell, a bearing plate, a second fixing block, a drive motor, a drive gear, a clamping plate, a compression spring, a support rod, and a pressure rod. A bearing plate is movably mounted in the middle of the bearing shell. Second fixing blocks are respectively mounted on both sides of the bearing shell near the front end of the support column. Drive motors are respectively mounted on the outer sides of the two second fixing blocks, and drive gears are respectively mounted on the two drive motors. Multiple compression springs are mounted in the middle of the bearing shell, and the compression springs are located below the bearing plate. Symmetrical support rods are respectively mounted on both sides inside the bearing shell. Connecting rods are respectively hinged to the two support rods. Clamping plates are mounted on the top ends of the two connecting rods. A pressure plate is provided on the side of the bearing plate away from the support column. One end of each of the two pressure rods is connected to the bottom inside the front end of the bearing shell, and the other end is connected to the bottom of the pressure plate. The horizontal end of the connecting rod is located below the pressure rod.

[0016] Multiple load-bearing mechanisms are installed on the rear side of the support columns, located above the vehicle body. The main function of the load-bearing mechanisms is to receive and secure the goods transferred from the lifting mechanism. Each load-bearing mechanism is equipped with a load-bearing plate. When the goods are lifted above the load-bearing plate, the lifting motor drives the goods to descend, and the goods press down on the load-bearing plate under their own weight, causing the load-bearing plate to move downward.

[0017] The downward movement of the support plate triggers the clamping plates on both sides. The clamping plates move downwards, compressing the springs, which in turn move the pressure plate downwards, pushing the inclined pressure rod. The pressure rod further drives the horizontal end of the connecting rod downwards. The vertical end of the connecting rod then pushes the clamping plates inwards, thereby clamping and securing the goods. This clamping mechanism effectively prevents goods from shaking, tilting, or slipping during transportation, ensuring the stability of the goods during stacking.

[0018] Preferably, a first slide rail is installed on the front side of each of the two support columns, and a plurality of second fixed teeth are provided on the front side of each of the two first slide rails, and the second fixed teeth mesh with the first gear. A second slide rail is installed on the rear side of each of the two support columns, and a plurality of third fixed teeth are provided on the outer side of each of the two second slide rails, and the third fixed teeth mesh with the drive gear.

[0019] The second fixed tooth on the first slide rail serves to transmit power, used for raising or lowering the lifting mechanism. Similarly, the third fixed tooth on the second slide rail also serves to transmit power, used for adjusting the distance between the load-bearing mechanisms.

[0020] Preferably, the two clamping plates have an arc-shaped structure, and multiple rubber pads are installed on the inner side of each of the two clamping plates. The rubber pads are used to ensure that the goods are not damaged during the clamping process, and at the same time, they increase the friction between the goods and the clamping blocks, thereby improving the stability of the clamping performance.

[0021] Preferably, the connecting rod has an L-shaped structure, and the horizontal end of the L-shaped structure is hinged to the pressure rod. The L-shaped connecting rod is designed to ensure that when the goods are placed on the support plate, the clamping plate can be driven to move inward and clamp and fix the goods.

[0022] Preferably, the two first slide rails slide in a sliding engagement with the first fixing block on both sides, and the two second slide rails slide in a sliding engagement with the second fixing block on both sides.

[0023] By having the first and second fixed blocks slide on the first and second slide rails, the entire load-bearing mechanism and lifting mechanism can operate stably while carrying goods, thereby improving the stability and safety of cargo transportation.

[0024] Preferably, the downward movement of the support plate is equal to the relative movement of the two clamping plates towards each other. This is to ensure that after the goods are placed on the support plate, the clamping plates can clamp and fix the goods in place, preventing them from tilting and improving the stability of transportation.

[0025] The beneficial effects of this invention are as follows: 1. This invention features a lifting mechanism and a carrying mechanism on the vehicle body. The lifting mechanism and the carrying mechanism work together to lift the goods and place them on the carrying mechanism. The carrying mechanism adjusts the distance between adjacent carrying mechanisms according to the height of the goods. At the same time, the carrying mechanism clamps and fixes the goods to prevent them from rolling or tilting during transportation, which greatly improves the efficiency of stacker crane transportation and stacking.

[0026] 2. This invention provides a carrying plate and a clamping plate on the carrying mechanism. The weight of the goods themselves causes the carrying plate to move downwards, which in turn drives the clamping plates on both sides of the carrying plate to move towards each other, thus clamping and fixing the goods. This ensures the stability of the goods during transportation and improves the efficiency of stacker crane transportation and stacking.

[0027] 3. This invention features a moving motor and a lifting motor on the lifting mechanism. Through the cooperation of the moving motor and the lifting motor, the forks lift the entire cargo to a certain height, and the horizontal movement of the forks places the cargo on the support plate, thereby completing the loading of the cargo.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely represents some embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0044] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," and "back side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is conventionally placed during use. These terms are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on the invention.

[0045] It should also be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0046] This disclosure aims to address the problems of existing stacker cranes, where excessively high stacking speeds can cause soft goods to become unstable, leading to rolling and tipping. Furthermore, different goods of varying heights require different stacker cranes, reducing stacking efficiency. Therefore, this disclosure proposes an unmanned warehouse stacking vehicle. This vehicle is equipped with a lifting mechanism and a carrying mechanism. These mechanisms work together to lift and place goods onto the carrying mechanism. The carrying mechanism adjusts the distance between adjacent carrying mechanisms based on the goods' height and clamps the goods to prevent rolling and tilting during transport, significantly improving stacker crane efficiency. Additionally, the carrying mechanism includes a carrying plate and clamping plates. The weight of the goods causes the carrying plate to move downwards, driving the clamping plates on both sides to move towards each other, clamping and securing the goods. This ensures stability during transport and further enhances stacker crane efficiency.

[0047] like Figures 1 to 12 As shown, a warehouse stacking unmanned vehicle includes: a vehicle body 1 and support columns 2; two support columns 2 are vertically installed at the front end of the vehicle body 1; it also includes a lifting mechanism 3 and a carrying mechanism 4; the lifting mechanism 3 is movably installed on the front side of the support columns 2, and multiple carrying mechanisms 4 are respectively installed on the rear side of the support columns 2, with the carrying mechanisms 4 located above the vehicle body 1. The lifting mechanism 3 drives the fork 34 to enter the bottom of the goods through a moving motor 32, and then drives the fork 34 to move upward through a lifting motor 33, lifting the goods and placing them on the carrying plate 42 on the carrying mechanism 4. The goods move downward by their own gravity, causing the carrying plate 42 to move downward, driving the clamping plates 46 on both sides of the carrying plate 42 to move towards each other and clamp and fix the goods.

[0048] This automated warehouse stacking vehicle is suitable for various warehousing and logistics scenarios, especially large warehouses, logistics centers, and high-density storage areas. It can efficiently complete the stacking, handling, and storage of goods, significantly improving the automation level and operational efficiency of the warehouse, while reducing labor costs and operational risks.

[0049] like Figures 4 to 7As shown, the lifting mechanism 3 includes a housing 31, a moving motor 32, a lifting motor 33, forks 34, a first fixing block 35, a fixing seat 36, a first rotating shaft 37, and a second rotating shaft 38. The moving motor 32 is installed at one end of the housing 31, and the lifting motor 33 is installed at the other end. Two parallel forks 34 are movably installed on the top of the housing 31. The first fixing block 35 is installed at both ends of the housing 31 near the support column 2. The fixing seat 36 is installed inside the housing 31. The first rotating shaft 37 and the second rotating shaft 38 are rotatably installed on the fixing seat 36, and the first rotating shaft 37 and the second rotating shaft 38 are parallel to each other. The first rotating shaft 37 is connected to the lifting motor 33, and the second rotating shaft 38 is connected to the moving motor 32.

[0050] The lifting mechanism 3 is movably mounted on the front side of the support column 2 and is a key component for the unmanned vehicle to grasp and lift goods. The lifting mechanism 3 drives the fork 34 to move horizontally via the moving motor 32, allowing the fork 34 to accurately extend into the bottom of the goods. The rotation of the moving motor 32 drives the fork 34 to move outward or inward through the gear transmission system, ensuring that the fork 34 can accurately position the goods.

[0051] Once the fork lever 34 reaches the bottom of the goods, the lifting motor 33 starts, driving the fork lever 34 to move upwards and lift the goods from the ground or shelf. The rotation of the lifting motor 33, through a drive shaft and gear system, drives the entire lifting mechanism 3 to rise or fall vertically along the support column 2. The design of the lifting mechanism 3 allows goods to be lifted smoothly and quickly to the designated height, preparing for subsequent goods transfer.

[0052] A movable motor 32 is mounted at one end of the housing 31 and is responsible for driving the horizontal movement of the fork 34. The output shaft of the movable motor 32 is connected to a second rotating shaft 38, which meshes with a first fixed tooth 341 on the fork 34 via a gear transmission system. When the movable motor 32 is started, the second rotating shaft 38 begins to rotate, driving the fork 34 to move outward or inward, thereby realizing the extension and retraction function of the fork 34. This design allows the fork 34 to accurately position the goods, ensuring that the goods can be successfully grasped.

[0053] A lifting motor 33 is mounted at the other end of the housing 31 and is responsible for driving the vertical movement of the lifting mechanism 3. The output shaft of the lifting motor 33 is connected to a first rotating shaft 37, which meshes with a second fixed gear 211 on the first slide rail 21 via a gear transmission system. When the lifting motor 33 is started, the first rotating shaft 37 begins to rotate, driving the entire lifting mechanism 3 to move up and down along the first slide rail 21. This design allows the lifting mechanism 3 to be flexibly adjusted according to the height of the goods, ensuring that the goods can be accurately lifted or lowered to a specified height.

[0054] like Figure 6 As shown, the bottom of the two forks 34 are respectively provided with first fixed teeth 341, the two ends of the first rotating shaft 37 are provided with first gears 371, and the second rotating shaft 38 is provided with second gears 381, and the second gears 381 mesh with the first fixed teeth 341.

[0055] like Figure 7 As shown, the fixed base 36 is provided with a first shaft hole 361 and a second shaft hole 362 horizontally, and the first shaft hole 361 cooperates with the first rotating shaft 37, and the second shaft hole 362 cooperates with the second rotating shaft 38.

[0056] like Figures 8 to 10 As shown, the bearing mechanism 4 includes a bearing shell 41, a bearing plate 42, a second fixing block 43, a drive motor 44, a drive gear 45, a clamping plate 46, a compression spring 47, a support rod 48, and a pressure rod 49. The bearing plate 42 is movably mounted in the middle of the bearing shell 41. Second fixing blocks 43 are respectively installed on both sides of the bearing shell 41 near the front end of the support column 2. Drive motors 44 are respectively installed on the outer sides of the two second fixing blocks 43, and drive gears 45 are respectively installed on the two drive motors 44. Multiple compression springs are installed in the middle of the bearing shell 41. 47, and the compression spring 47 is located below the bearing plate 42. Symmetrical support rods 48 are installed on both sides inside the bearing shell 41. Connecting rods 481 are hinged to the two support rods 48 respectively. Clamping plates 46 are installed at the top of the two connecting rods 481. A pressure plate 421 is provided on the side of the bearing plate 42 away from the support column 2. One end of the two pressure rods 49 is connected to the bottom inside the front end of the bearing shell 41, and the other end is connected to the bottom of the pressure plate 421. The horizontal end of the connecting rod 481 is located below the pressure rod 49.

[0057] During the cargo lifting process, sensors on the vehicle body 1 detect the cargo's height in real time and feed this information back to the control system. Based on the cargo's height, the control system adjusts the drive motor 44 on the carrying mechanism 4, causing the drive gear 45 to rotate. Because the drive gear 45 meshes with the third fixed gear 221 on the second slide rail 22, the entire carrying mechanism 4 moves up and down, ensuring that the distance between two adjacent carrying mechanisms 4 is greater than the cargo's height. This design guarantees that the cargo can be smoothly placed on the carrying mechanism 4 without collision or compression.

[0058] like Figures 1 to 3As shown, a first slide rail 21 is installed on the front side of each of the two support columns 2. A plurality of second fixed teeth 211 are provided on the front side of each of the two first slide rails 21, and the second fixed teeth 211 mesh with the first gear 371. A second slide rail 22 is installed on the rear side of each of the two support columns 2. A plurality of third fixed teeth 221 are provided on the outer side of each of the two second slide rails 22, and the third fixed teeth 221 mesh with the drive gear 45.

[0059] On the front side of each of the two support columns 2, a first slide rail 21 is installed. The design of the first slide rail 21 provides precise guidance and support for the vertical movement of the lifting mechanism 3. Multiple second fixed teeth 211 are provided on the front side of the first slide rail 21, and these second fixed teeth 211 mesh with the first gear 371 on the lifting mechanism 3. When the lifting motor 33 is started, the rotation of the first gear 371 drives the lifting mechanism 3 to move up and down along the first slide rail 21. The distribution density of the second fixed teeth 211 and the meshing precision of the gears ensure the smoothness and positioning accuracy of the lifting mechanism 3 during movement, thereby enabling the goods to be precisely lifted or lowered to a designated height.

[0060] On the rear side of the support column 2, a second slide rail 22 is installed. The function of the second slide rail 22 is to provide guidance and support for the vertical movement of the carrying mechanism 4. Multiple third fixed teeth 221 are provided on the outer side of the second slide rail 22, and these third fixed teeth 221 mesh with the drive gear 45 on the carrying mechanism 4. When the drive motor 44 on the carrying mechanism 4 starts, the rotation of the drive gear 45 will drive the carrying mechanism 4 to move up and down along the second slide rail 22. The height of the goods is detected in real time by sensors on the vehicle body 1, allowing the carrying mechanism 4 to flexibly adjust according to the height of the goods, ensuring that the distance between two adjacent carrying mechanisms 4 is always greater than the height of the goods, thereby avoiding collisions or compression of the goods during stacking.

[0061] like Figures 8 to 10 As shown, the two clamping plates 46 have an arc-shaped structure, and multiple rubber pads 461 are respectively installed on the inner side of the two clamping plates 46.

[0062] The rubber pad 461 is used to ensure that the goods are not damaged during the clamping process. At the same time, it increases the friction between the goods and the clamping plate 46, thereby improving the stability of the clamping.

[0063] like Figure 9 and Figure 10 As shown, the connecting rod 481 has an L-shaped structure, and the horizontal end of the L-shaped structure is hinged to the pressure rod 49. The L-shaped connecting rod 481 is designed to ensure that when the goods are placed on the bearing plate 42, the clamping plate 46 can be driven to move inward and clamp and fix the goods.

[0064] like Figure 11 and Figure 12 As shown, the two first slide rails 21 are slidably engaged with the first fixing block 35 on both sides, and the two second slide rails 22 are slidably engaged with the second fixing block 43 on both sides.

[0065] By having the first fixed block 35 and the second fixed block 43 slide on the first slide rail 21 and the second slide rail 22, the entire carrying mechanism 4 and the lifting mechanism 3 can operate stably while carrying the goods, thereby improving the stability and safety of cargo transportation.

[0066] The downward movement of the bearing plate 42 is equal to the downward movement of the two clamping plates 46 towards each other.

[0067] Once all goods are loaded onto the carrying mechanism 4, the vehicle body 1 begins to move, transporting the goods to the designated shelf location. Upon arrival at the shelf, the lifting motor 33 restarts, driving the forks 34 to lift the goods. Subsequently, the moving motor 32 drives the forks 34 to move outward, smoothly placing the goods onto the shelf. At this point, the entire goods stacking process is complete.

[0068] The entire stacking process involves the coordinated operation of multiple components such as motors, gears, slide rails, and sensors, ensuring precise positioning, stable clamping, and safe transportation of goods during stacking. Through this series of complex mechanical actions, the stacker crane can efficiently and accurately complete the stacking task, greatly improving the automation level and work efficiency of warehousing and logistics.

[0069] In the working process of this invention: When the stacker crane is stacking, firstly, the moving motor 32 needs to be started. The moving motor 32 rotates, driving the second rotating shaft 38 to rotate. Since the second gear 381 on the second rotating shaft 38 meshes with the first fixed tooth 341 on the fork 34, it will drive the fork 34 to move outward. Subsequently, the lifting motor 33 starts, driving the first rotating shaft 37 to rotate. Since the second gear 381 meshes with the second fixed tooth 211 on the first slide rail 21, it will drive the entire lifting mechanism 3 to descend to the lowest point. The first fixed block 35 slides on both sides of the first slide rail 21. The vehicle body 1 moves and moves to the front of the goods. The fork 34 enters the bottom of the goods. The lifting motor 33 rotates in the opposite direction, driving the entire lifting mechanism 3 and the goods... The object is lifted upwards to the height of the supporting mechanism 4. Then, the moving motor 32 rotates in the opposite direction and drives the fork 34 to move the object onto the supporting mechanism 4. When the object moves above the supporting plate 42, the lifting motor 33 moves the object downwards. When the bottom of the object contacts the supporting plate 42, the weight of the object will cause the supporting plate 42 to move downwards. The compression spring 47 at the bottom of the supporting plate 42 will be compressed, and the supporting plate 42 will move the pressure plate 421 downwards together. The pressure plate 421 will move the inclined pressure rod 49 downwards and push the horizontal end of the connecting rod 481 downwards. The vertical end of the connecting rod 481 will move the clamping plate 46 inwards, thereby clamping and fixing the object to prevent it from rolling or tilting.

[0070] During the lifting process, the sensors on the vehicle body 1 will detect the height of the cargo, thereby controlling the drive motor 44 on the carrying mechanism 4 to drive and drive the drive gear 45 to rotate. Since the drive gear 45 meshes with the third fixed tooth 221 on the second slide rail 22, the entire carrying mechanism 4 will move up and down. The second fixed block 43 slides on both sides of the second slide rail 22, ensuring that the distance between two adjacent carrying mechanisms 4 is greater than the height of the cargo, so that the cargo can be placed on the carrying mechanism 4.

[0071] Once all the goods are loaded onto the carrying mechanism 4, the vehicle body 1 will move the goods to the designated shelf and lift the goods by using the lifting motor 33 to drive the forks 34. Then, the moving motor 32 will drive the forks 34 to move outward and place them on the shelf, thus completing the stacking of the entire goods.

[0072] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
