[0002] A lifting mobile robot is a transport vehicle that can lift objects and travel along a prescribed guide path. It has safety protection and various transfer functions. Due to its high degree of automation, safety and flexibility, it is widely used in automated production and production transportation in automobile manufacturing, machinery processing and other fields.

[0003] Existing lifting mobile robots are used in furniture production and transportation. Because tables, chairs and other furniture have different heights, the lifting height required by the lifting mobile robots varies. However, most existing lifting mobile robots only use hydraulic push rods to lift items, which has a limited lifting height and cannot be used for various types of furniture with different heights. Therefore, we need to propose a lifting mobile robot. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides: a lifting mobile robot, such as... Figure 1-4 As shown, it includes a movable base plate 1, a mounting plate 2 and a lifting plate 3. A hydraulic push rod 10 is fixedly installed on the upper surface of the movable base plate 1, and the mounting plate 2 is fixedly installed on the working end of the hydraulic push rod 10.

[0024] The upper surface of the mounting plate 2 is provided with a lifting component for driving the lifting plate 3 to rise and fall twice. The lifting plate 3 is set on the upper surface of the mounting plate 2 through the lifting component.

[0025] The lifting assembly includes a connecting column 4, a connecting ring 12, an extension rod 19, a drive module, and a connecting module. The connecting ring 12 is fixedly installed at one end of the extension rod 19 and is sleeved on the outer arc surface of the connecting column 4. Two sets of connecting modules are provided, and the extension rod 19 is connected to one set of connecting modules. The lifting plate 3 is lifted once by the hydraulic push rod 10, and then the extension rod 19 is moved by the drive module, thereby causing the swing column 13 to rotate around the connecting column 14 as the center, and then the lifting plate 3 is lifted a second time, thereby increasing the lifting height of the lifting mobile robot.

[0026] Preferably, both sets of connecting modules include a swing column 13, a connecting column 14, a connecting side plate 15, an extension column 16, and a bolted plate 17. The connecting side plate 15, extension column 16, and bolted plate 17 are disposed in two sets. The swing column 13 and connecting column 14 are rotatably disposed between the two sets of connecting side plates 15. The two sets of extension columns 16 are rotatably disposed on opposite sides of the two sets of connecting side plates 15, and the two sets of extension columns 16 are correspondingly disposed to the connecting column 14. The swing column 13 and connecting column 14 are located between the two sets of connecting side plates 15. When the side plates 15 rotate and the lifting plate 3 is laid flat, the swing column 13 is located to the right of the connecting column 14. When the lifting plate 3 is raised, the swing column 13 is located above the connecting column 14. The two sets of connecting side plates 15 are rotatably set inside the placement groove 7 through the two sets of extension columns 16. When the swing column 13 and the connecting side plates 15 rotate, they rotate around the extension column 16 as the center. The positions of the connecting column 14 and the extension column 16 correspond, so that the position of the connecting column 14 will not change when the connecting side plates 15 rotate.

[0027] Furthermore, both sets of bolted plates 17 are rotatably sleeved on the outer arc surface of the swing column 13, and the upper surfaces of the two sets of bolted plates 17 are bolted to the lower surface of the lifting plate 3. The two sets of bolted plates 17 do not contact the connecting side plate 15, thereby avoiding the bolted plates 17 from rubbing against the connecting side plate 15 when rotating. When the swing column 13 rotates, the lifting plate 3 is driven to rise and fall through the two sets of bolted plates 17, thereby achieving the purpose of driving the lifting plate 3 to lift twice.

[0028] Furthermore, the drive module includes a sleeve post 4, a support plate 5, a servo motor 6, and a rotating post 20. Two sets of support plates 5 are provided, and the two sets of support plates 5 are fixedly installed on the upper surface of the mounting plate 2. The rotating post 20 is rotatably disposed between the two sets of support plates 5. One end of the rotating post 20 is keyed to the output end of the servo motor 6, and the servo motor 6 is bolted to the upper surface of the mounting plate 2. When the servo motor 6 is started, it drives the rotating post 20 to rotate, and the two sets of support plates 5 support the rotating post 20, thereby ensuring the stability of the rotating post 20 when rotating.

[0029] It is worth noting that the sleeve post 4 is fixedly sleeved on the outer arc surface of the rotating post 20, and the sleeve post 4 is located between the two sets of support plates 5. The end of the sleeve post 4 away from the rotating post 20 is fixedly installed with a limiting post 9. The sleeve post 4 is rotatably set between the two sets of support plates 5, thereby ensuring the stability when the rotating post 20 drives the sleeve post 4 to rotate. The limiting post 9 is set to limit the sleeve ring 12 to prevent the sleeve ring 12 from sliding out from the outer arc surface of the sleeve post 4.

[0030] Specifically, two sets of snap-fit ​​plates 18 are fixedly installed at the end of the extension rod 19 away from the sleeve ring 12. The two sets of snap-fit ​​plates 18 are rotatably sleeved on the outer arc surface of a set of swing columns 13. The side of the lifting plate 3 is provided with anti-collision grooves 11 corresponding to the snap-fit ​​plates 18. When the sleeve column 4 rotates around the rotating column 20, it drives the snap-fit ​​plates 18 to move through the extension rod 19. The snap-fit ​​plates 18 drive a set of swing columns 13 to rotate around the extension column 16, thereby driving the lifting plate 3 to rise and fall. At the same time, another set of swing columns 13 will rotate with the lifting plate 3, thereby supporting the lifting plate 3 through the two sets of connecting modules, thereby improving the load-bearing capacity of the lifting plate 3.

[0031] In addition, the upper surface of the mounting plate 2 is provided with a placement groove 7 corresponding to the lifting plate 3. The upper surface of the lifting plate 3 is provided with an anti-slip pad. Several sets of moving wheels 8 are rotatably provided on the side of the movable base plate 1. The placement groove 7 is provided to ensure that the lifting component will not rub against the mounting plate 2 when it is working. At the same time, other equipment for the robot can be placed inside the placement groove 7. The anti-slip pad on the surface of the lifting plate 3 improves the stability when lifting items. At the same time, the robot moves as a whole through the several sets of moving wheels 8.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
