Description

Technical Field

[0001] This utility model relates to the field of intelligent robot technology, and in particular to a hydraulic lifting and rotating structure for a stealthy intelligent robot and a stealthy robot made therefrom. Background Technology

[0002] Currently, the lifting and rotating structures of lurking robots on the market typically employ multi-link or multi-screw structures (such as CN216735876U). As a result, the overall lifting structure is relatively large, which is not conducive to the design and layout of the internal structure of the mobile robot and requires a large amount of internal space.

[0003] At the same time, such structures have many components, making production and assembly more complex and costly. They are also prone to quality defects such as abnormal noises after long-term use, making after-sales maintenance difficult. More importantly, multi-link or multi-screw structures have high requirements for the spatial layout of the robot chassis and have poor versatility. Utility Model Content

[0004] Therefore, the main objective of this utility model is to provide a lifting and rotating structure and a locomotive made therefrom, so as to achieve a compact design of the lifting mechanism and reduce the requirements for robot chassis space and layout.

[0005] To achieve the above objectives, according to one aspect of the present invention, a lifting and rotating structure is provided, comprising: a rotating unit, a lifting base plate, and a hydraulic lifting unit, wherein the hydraulic lifting unit comprises: a fixed base, a drive pump, and a hydraulic cylinder, wherein the drive pump and the hydraulic cylinder are disposed on the fixed base, the fixed base is provided with a hydraulic pipeline connecting the drive pump and the hydraulic cylinder, the telescopic end of the hydraulic cylinder is connected to the lifting base plate, and the rotating unit is disposed on the lifting base plate.

[0006] Preferably, the rotating unit includes: a servo motor, a rotating support gear, a bearing component, and a driven gear, wherein the servo motor is mounted on the bottom surface of the lifting base plate; the driven gear is connected to the servo motor and arranged on the top surface of the lifting base plate; the rotating support gear is connected to the top surface of the lifting base plate via the bearing component and meshes with the driven gear.

[0007] Preferably, the lifting and rotating structure further includes: a base plate frame and a guide column, wherein the hydraulic lifting unit is connected to the base plate frame via a fixed seat, the bottom of the guide column is fixed to the base plate frame, and the guide end is connected to the lifting base plate.

[0008] Preferably, the lifting and rotating structure further includes a limit sensing unit, which includes a bracket, a limit sensor, and a trigger, wherein the trigger is fixed on the lifting base plate, the bracket is fixed on the base plate, the limit sensor is disposed on the bracket and arranged at preset lifting limit distance intervals, and the sensing end of the limit sensor faces the lifting path of the trigger.

[0009] Preferably, the lifting and rotating structure further includes a rotation origin sensor, which is disposed on the lifting base plate, and the sensing end of the rotation origin sensor faces the surface of the rotating support gear.

[0010] To achieve the above objectives, according to another aspect of the present invention, a stealthy robot is also provided, comprising: a lifting and rotating structure as described above.

[0011] The lifting and rotating structure provided by this utility model and the lurking robot made from it ingeniously design a hydraulic lifting unit to integrate the drive pump and hydraulic cylinder on the fixed base. The hydraulic pipeline set in the fixed base replaces the external hydraulic pipeline, thus forming a compact modular design. This design has lower requirements for the robot chassis space layout and is more universal. This solution not only saves space, but also has fewer parts, which can effectively reduce assembly costs. As a core drive component, this modular design is more conducive to disassembly, replacement and maintenance. Moreover, the overall hydraulic structure is less likely to produce structural transmission noise. Compared with the traditional multi-link and screw drive lifting structure solution, it has a higher maximum load potential. Attached Figure Description

[0025] To achieve a compact design of the lifting mechanism inside existing stealth robots and reduce the requirements for robot chassis space and layout, such as... Figures 1 to 5 As shown, this utility model provides a lifting and rotating structure, an example of which includes: a rotating unit 1, a lifting base plate 2, and a hydraulic lifting unit 3.

[0026] To reduce the overall size of the lifting structure and achieve a modular design for easier replacement and maintenance, such as... Figures 4 to 5 As shown, the hydraulic lifting unit 3 example includes: a fixed base 31, a drive pump 32, and a hydraulic cylinder 33, wherein the drive pump 32 and the hydraulic cylinder 33 are both mounted on the fixed base 31, and the fixed base 31 is provided with a hydraulic pipeline that connects the drive pump 32 and the hydraulic cylinder 33. The telescopic end of the hydraulic cylinder 33 is connected to the lifting base plate 2, and the rotating unit 1 is mounted on the lifting base plate 2.

[0027] There are several ways to implement the hydraulic pipeline. For example, multiple hydraulic pipes connecting the drive pump 32 and the hydraulic cylinder 33 can be connected by drilling holes in the fixed base 31; or the fixed base 31 can be divided into two parts, and oil grooves for connecting the interfaces can be engraved on the inner surface and then sealed together to establish a hydraulic pipeline. This integrates the hydraulic pipeline with the fixed base 31, providing oil access for the drive pump 32 and the hydraulic cylinder 33, and also providing base fixation, thus constructing a compact modular hydraulic lifting unit 3. Compared with the traditional exposed oil pipe structure, this eliminates the problems of exposed oil pipe connection and management, making production and assembly more convenient, and reducing the space requirements for the robot chassis layout.

[0028] Furthermore, in order to support and guide the lifting of the hydraulic lifting unit 3 and improve the reliability of the lifting structure, such as... Figures 1 to 4As shown, the lifting and rotating structure further includes: a base plate frame 21 and guide columns 22, wherein the hydraulic lifting unit 3 is connected to the base plate frame 21 via a fixed seat 31, and the guide columns 22 are preferably four linear bearings, with their bottoms fixed to the base plate frame 21 and their guide ends connected to the lifting base plate 2, so as to guide the lifting base plate 2 from four points and ensure that the hydraulic lifting unit 3 is lifted vertically along the longitudinal direction.

[0029] Furthermore, to support the mounting rack 7 of the equipped stealth robot, it not only has lifting capabilities but also rotation capabilities, such as... Figures 1 to 3 As shown, the rotating unit 1 example includes: a servo motor 11, a rotating support gear 12, a bearing, and a driven gear 13. The servo motor 11 is mounted on the bottom surface of the lifting base plate 2; the driven gear 13 is connected to the servo motor 11 and arranged on the top surface of the lifting base plate 2; the rotating support gear 12 is connected to the top surface of the lifting base plate 2 via the bearing and meshes with the driven gear 13. This allows for horizontal rotation without affecting the vertical lifting of the lifting base plate 2.

[0030] Furthermore, to prevent over-limit lifting, such as Figures 2 to 3 As shown, the lifting and rotating structure also includes, for example, a limit sensing unit 4, which includes a bracket 41, a limit sensor 42, and a trigger 43. The trigger 43 is fixed on the lifting base plate 2, the bracket 41 is fixed on the base plate frame 21, and a pair of limit sensors 42 are arranged on the bracket 41 at preset lifting limit distance intervals. The sensing end of the limit sensor 42 faces the lifting path of the trigger 43.

[0031] Furthermore, in order to sense the rotation of the rotary support gear 12, such as Figures 1 to 3 As shown, the lifting and rotating structure also includes, for example, a rotation origin sensor 5, which is disposed on the lifting base plate 2, with the sensing end of the rotation origin sensor 5 facing the wheel surface of the rotating support gear 12. This allows it to sense the origin signal of the rotating support gear 12.

[0032] On the other hand, such as Figures 6 to 7 As shown, corresponding to the above example of the lifting and rotating structure, this utility model also provides a stealthy robot, which includes: a robot chassis 6, a support shelf 7, and a lifting and rotating structure 8 as described above, wherein the lifting and rotating structure 8 is disposed in the robot chassis 6, and the support shelf 7 is fixed on the rotating support gear 12.

[0033] In summary, the lifting and rotating structure provided by this utility model and the resulting stealthy robot cleverly design a hydraulic lifting unit 3 to integrate the drive pump 32 and hydraulic cylinder 33 onto the fixed base 31. The hydraulic lines installed within the fixed base 31 replace external hydraulic lines, thus forming a compact modular design. This design places lower demands on the robot chassis space layout and offers greater versatility. This solution not only saves space but also reduces assembly costs due to fewer components. Furthermore, as a core drive component, this modular design facilitates disassembly, replacement, and maintenance. The overall hydraulic structure is less prone to structural transmission noise and has a higher maximum load potential compared to traditional multi-link and screw-driven lifting structures.
