[0029] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means two or more.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense.

Any embodiment or design described as "exemplarily" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a concrete manner.

[0035] A jacking mechanism is a mechanical device that is mainly used to lift heavy objects or loads in the vertical direction. It plays an important role in modern industry and daily life, helping to improve work efficiency and safety. Lifting mechanisms are commonly used in construction, industry, transportation and other fields to facilitate the handling, installation or maintenance of heavy objects. For example, it is used in AMR (Autonomous Mobile Robot) carts. AMR carts are usually used in warehousing, logistics, production lines and other environments. The jacking mechanism is set on the AMR cart for transportation, handling items, etc. For another example, during the machining process, the jacking mechanism can help demold the product in the mold. For another example, the jacking mechanism can be used in equipment such as lifts, elevators, and forklifts to achieve vertical lifting of objects. Most jacking mechanisms achieve the jacking action by setting a drive part.

[0036] In the related art, the jacking mechanism usually uses a driving motor as the power to drive the jacking assembly to achieve jacking. Figure 1 as well as Figure 2 , Figure 1 This is a structural diagram of the jacking structure shown in the related art of this application. Figure 2 For this application Figure 1 The bottom view of the jacking structure shown in the figure shows that the jacking structure 1 includes a mounting plate 2, a plurality of guide sleeves 3 are symmetrically fixedly embedded on both sides of the mounting plate 2, guide racks 4 are slidably provided in the guide sleeves 3, a lifting plate 5 is fixed between the upper ends of the guide racks 4, and a reversing reduction motor 6 is fixed to one end of the lower surface of the mounting plate 2.

[0037] However, this jacking structure requires a large space due to the limitation of its overall structure.

[0038] Based on this, see Figure 3 , Figure 3 This is a schematic diagram of the structure of a transport device according to an embodiment of the present application. The present application provides a transport device 100, which includes a support platform 10 and a lifting mechanism 20. The lifting mechanism 20 is mounted on the support platform 10. The lifting mechanism 20 can be used to lift an object to a desired height or lower it back to its original position to achieve the purpose of transportation or installation.

[0039] In some embodiments, the transport device 100 may be an AMR (Automated Robotic Automated Recycling) vehicle, with the lifting mechanism 20 mounted on the vehicle's body. The AMR's body is also equipped with sensors, cameras, and other features that enable it to autonomously avoid obstacles, plan routes, and carry items. In other embodiments, the transport device 100 may be an elevator, with the lifting mechanism 20 mounted on the elevator's body, and may be used for transporting goods or performing vehicle repairs.

[0040] For details, see Figure 4 , Figure 4This is a structural schematic diagram of a jacking mechanism shown in an embodiment of the present application. The present application provides a jacking mechanism 20, including a rotating member 30, a driving member 40 and a plurality of jacking components 50.

[0041] The driving member 40 is in transmission connection with the rotating member 30 and is used to drive the rotating member 30 to rotate about its central axis. It will be appreciated that the driving member 40 can be powered by a variety of means, such as an electric motor, a hydraulic system, or a mechanical transmission. The output shaft of the driving member 40 is connected to an output gear 41, which is in transmission connection with the rotating member 30.

[0042] In some embodiments, the drive element 40 is a brake motor. This allows the lifting mechanism 20 to quickly apply braking force when it encounters an emergency or requires emergency shutdown, preventing further operation. Furthermore, when the lifting mechanism 20 stops, the brake motor locks mechanical components, preventing movement of the lifting mechanism 20 due to factors such as gravity, allowing the lifting mechanism 20 to stop at any height within its travel range. Furthermore, brake motors generally utilize electromagnetic principles, offering advantages such as fast response and excellent stability.

[0043] See also Figure 5 , Figure 5 For this application Figure 4 In the schematic structural diagram of the jacking mechanism viewed from direction A, multiple jacking assemblies 50 are arranged at intervals along the circumference of the rotating member 30 and are transmission-connected to the rotating member 30. This can make the load more uniform, reduce the risk of local overload, and increase the reliability of the jacking mechanism 20.

[0044] It should be noted that the number of the lifting assemblies 50 can be 2, 3, 4, 5, 6, etc. This application does not impose any limitation on this, and the limitation is made according to actual conditions.

[0045] For example, the present application is described by taking the example that the number of the jacking assemblies 50 may be 3.

[0046] The rotating member 30 rotates about its central axis, causing the multiple lifting assemblies 50 to ascend or descend along the central axis. The lifting mechanism 20, via the driver 40, drives the rotating member 30 to rotate, which in turn drives the lifting assemblies 50 to ascend or descend, enabling rapid lifting and descending operations and improving work efficiency. The multiple lifting assemblies 50 are spaced apart along the circumference of the rotating member 30, eliminating the need for a complex transmission system, resulting in a simple structure and easy maintenance.

[0047] In addition, this can also save space and reduce the space occupied by the jacking mechanism 20, thereby expanding the application possibilities of the jacking mechanism 20 in different fields.

[0048] In some embodiments, the lifting mechanism 20 further includes a base 60, on which the rotating member 30, the driving member 40, and the plurality of lifting assemblies 50 are disposed. The base 60 is provided with connection holes, and the lifting mechanism 20 can connect the base 60 to the support platform 10 of the transport device 100 using screws, bolts, or the like.

[0049] In some embodiments, see Figure 4 The rotating member 30 includes a first ring gear 31 and a second ring gear 32 that are coaxially arranged and fixedly connected. The first ring gear 31 and the second ring gear 32 are arranged along the extension direction of the central axis of the rotating member 30. Thus, the coaxial design of the first ring gear 31 and the second ring gear 32 makes the overall structure of the jacking mechanism 20 more compact, reduces the space occupied by the rotating member 30, and helps to increase the flexibility of the overall design of the jacking mechanism 20.

[0050] That is to say, after the space occupied by the rotating part 30 is reduced, installation space can be provided for other equipment, and the jacking mechanism 20 can be flexibly designed according to needs, so that the jacking mechanism 20 can be widely used in different industrial occasions.

[0051] The driving member 40 is in transmission connection with the first ring gear 31, and is used to drive the first ring gear 31 to rotate about the central axis of the first ring gear 31. The second ring gear 32 is in transmission connection with the plurality of jacking assemblies 50, and the second ring gear 32 rotates about the central axis of the second ring gear 32 to cause the plurality of jacking assemblies 50 to rise or fall along the central axis of the second ring gear 32.

[0052] In this way, the power of the driving member 40 is transmitted to the lifting assembly 50 via the first and second ring gears 31, 32 of the rotating member 30, achieving efficient power transmission and reducing energy loss. In addition, this transmission method makes the lifting action of the lifting assembly 50 more precise and can adapt to different work requirements.

[0053] It should be noted that the first gear ring 31 and the second gear ring 32 can be arranged at intervals or adjacent to each other. This application does not limit this, and the specific limitation is made according to the actual situation. In some embodiments, continue to refer to Figure 5 The rotating member 30 further includes a fixed member 33 and a rotating member 34 that can rotate relative to each other. The first ring gear 31 and the second ring gear 32 are disposed on the rotating member 34, and the central axes of the first ring gear 31 and the second ring gear 32 are coaxial with the rotation axis of the rotating member 34 relative to the fixed member 33.

[0054] In this way, the central axes of the first gear ring 31 and the second gear ring 32 are coaxially arranged with the rotation axis of the rotating member 34, which can reduce the friction and wear between the fixed member 33 and the rotating member 34, extend the service life of mechanical parts, and reduce maintenance frequency.

[0055] It is understandable that the rotating member 30 may be a slewing bearing, or a worm gear structure, etc. This application does not impose any limitation on this, and the limitation may be made according to actual conditions.

[0056] In some embodiments, the fixing member 33 and the rotating member 34 are both annular, and the fixing member 33 encloses an accommodating space 331. The rotating member 34 is rotatably connected to the outer peripheral side of the fixing member 33.

[0057] As a result, the annular shape of both the fixed member 33 and the rotating member 34 effectively utilizes space. The accommodating space 331 enclosed by the fixed member 33 can be used to house other components or store required materials, thereby increasing the overall compactness of the lifting mechanism 20. Furthermore, the annular structure can more evenly distribute the load applied to the rotating member 34, reducing local stress concentration and extending the life of the rotating member 34.

[0058] In addition, by fixing the rotating member 34 on the outer peripheral side, it is easy to observe and inspect the rotating member 34, making daily maintenance and component replacement more convenient and saving maintenance time.

[0059] In some other embodiments, the fixing member 33 and the rotating member 34 are both annular, and the fixing member 33 encloses an accommodating space 331 . The rotating member 34 is rotatably connected to the inner circumference of the fixing member 33 .

[0060] In this way, since the rotating member 34 is enclosed within the fixed member 33 , the rotating member 34 can be effectively prevented from accidentally contacting the outside, thereby reducing the possibility of accidents and improving operational safety.

[0061] In some embodiments, see Figure 6 , Figure 6 This is a schematic structural diagram of a jacking assembly according to an embodiment of the present application. The jacking assembly 50 includes a first gear 51 and a second gear 52 that are coaxial and relatively fixed, as well as a rack 53 .

[0062] For details, see Figure 5 and combined Figure 6 The axes of the first gear 51 and the second gear 52 are both perpendicular to the central axis of the second ring gear 32, and the first gear 51 meshes with the second ring gear 32. This gear meshing provides efficient power transmission, reducing energy loss and improving efficiency during the lifting process. Furthermore, the relatively fixed gear design simplifies the structure, reduces space usage, and is suitable for compact equipment.

[0063] The length of the rack 53 is parallel to the central axis of the second ring gear 32, and the rack 53 meshes with the second gear 52. Rotation of the gear shaft drives the rack 53 up or down along its length. The rotational motion of the gear is effectively converted into linear motion, making the lifting and lowering operation smooth and efficient, reducing energy loss. Furthermore, the smooth meshing of the rack 53 and the gear reduces noise and vibration during operation of the lifting mechanism 20, resulting in a quieter operation.

[0064] In some other embodiments, see again Figure 6 The lifting assembly 50 further includes a mounting base 54 having first mounting holes 55 disposed thereon, the axial direction of the first mounting holes 55 being perpendicular to the central axis of the second gear ring 32. The first gear 51 and the second gear 52 are secured to the mounting base 54 via the first mounting holes 55. The mounting base 54 also includes a second mounting hole 56, the axial direction of which is parallel to the central axis of the second gear ring 32. The rack 53 is secured to the mounting base 54 via the second mounting hole 56. The second mounting hole 56 limits the movement of the rack 53, restricting it from rising or falling along the central axis of the second gear ring 32.

[0065] In some embodiments, the second ring gear 32 is a bevel gear, and the first gear 51 is a bevel gear. The bevel gear and bevel gear design can change the transmission direction by 90°, making it suitable for designs with limited space and helping to optimize the layout of the jacking mechanism 20. Furthermore, it can achieve smoother transmission, reduce vibration and noise, and improve the operational stability of the jacking mechanism 20.

[0066] In some embodiments, see again Figure 4 as well as Figure 5 The lifting mechanism 20 further comprises a lifting platform 70. Transport items can be placed on the lifting platform 70 to drive the transport items to rise or fall.

[0067] A fixing block 57 is located at the other end of the rack 53. The fixing block 57 has a larger cross-sectional area than the rack 53 and is used to connect to the jacking platform 70. The larger cross-sectional area of ​​the fixing block 57 provides better support for the jacking platform 70, helping to enhance the stability of the jacking mechanism 20 and prevent tilting or shaking during the lifting process. Furthermore, the fixing block 57 helps evenly distribute the load on the jacking platform 70, reducing the pressure per unit area of ​​the jacking platform 70 and thereby reducing the risk of material fatigue and damage.

[0068] It can be understood that the cross section refers to a cross section perpendicular to the length direction of the rack 53 .

[0069] In some embodiments, see Figure 6 and combined Figure 7 , Figure 7 The schematic diagram of the structure of the jacking platform shown in the embodiment of the present application shows a groove 71 on the side of the jacking platform 70 facing the rack 53, into which the fixing block 57 is accommodated. Groove 71 effectively secures the fixing block 57 in place, reducing lateral movement of the platform during operation and enhancing the stability of the overall structure. Furthermore, the design of groove 71 prevents the fixing block 57 from sliding or falling off during use, thereby ensuring a good connection between the jacking platform 70 and the rack 53.

[0070] It is understandable that the fixing block 57 can be located entirely or partially in the groove 71. This application does not limit this, and the specific limitation is determined based on actual conditions.

[0071] In some embodiments, see again Figure 4 The jacking mechanism 20 also includes a decoder 80, which is arranged between the rotating member 30 and the jacking platform 70. In this way, the decoder 80 can obtain the jacking signal that causes the jacking mechanism 20 to jack, and monitor and feedback the angle or position of the rotating member 30 in real time, thereby achieving more precise jacking control and improving the accuracy of the operation. At the same time, through real-time monitoring, the decoder 80 can promptly detect abnormal conditions, such as overload or position offset, and issue an alarm or automatically shut down, thereby improving the safety of the jacking mechanism 20. The decoder 80 can also provide feedback on the position of the jacking platform 70, which facilitates the operator to make judgments and adjustments, and ensures that the jacking mechanism 20 can respond accurately according to demand.

[0072] Optionally, the decoder 80 is used to read a barcode to obtain a lifting signal or a rotation signal by identifying the barcode.

[0073] Optionally, when the lifting mechanism 20 is used in an AMR cart, a barcode for being read by the decoder 80 can be set on the moving path of the AMR cart.

[0074] In some embodiments, the lifting mechanism 20 further includes a control component, which is used to receive the lifting signal and the rotation signal transmitted by the decoder 80 to move the lifting platform 70 upward or control the operation of the driving member 40.

[0075] During the specific implementation process, when a lifting operation is required, the decoder 80 is used to obtain a lifting signal to cause the lifting mechanism 20 to lift, and transmit the lifting signal to the control component. After receiving the lifting signal, the control component can control the driving member 40 to work so that the driving member 40 cooperates with the rotating member 30, and then drives the lifting assembly 50 to rise or fall along the central axis of the rotating member 30.

[0076] In some embodiments, the lifting mechanism 20 further includes a mounting bracket 90 , which is connected to the base 60 and is located between the rotating member 30 and the lifting platform 70 . The decoder 80 is fixed by the mounting bracket 90 .

[0077] In some other embodiments, the lifting mechanism 20 may further include sensors, cameras, and other devices. The sensors, cameras, and other devices may also be disposed between the rotating member 30 and the lifting platform 70 via the mounting bracket 90 .
