Description

Technical Field

[0001] This utility model relates to the field of robotics technology, specifically to an interactive robot. Background Technology

[0002] Interactive robots are widely used in mobile scenarios such as retail guidance, warehousing and logistics, public services, and home use. These robots need to frequently switch between multiple tasks (such as information display, human-computer interaction, and environmental inspection). Their screen components (i.e., iPads, tablets, or Android tablets) serve as the core interactive interface. They must not only meet the stability requirements during high-intensity movement but also adapt to flexible operating scenarios such as quick replacement and temporary handheld use. Especially in dynamic environments such as shopping mall guidance and factory inspection, the efficiency of screen module assembly and disassembly and the reliability of its use directly affect the practicality of the robot system and the user experience.

[0003] Currently, the screen components of interactive robots (i.e., iPads, tablets, or Android tablets) are installed on the mobile base using bolts or snap-fit ​​mechanical connections. However, during installation, manual pushing force is required for alignment and locking, which can easily cause unexpected displacement of the mobile base. That is, when the operator tightens the bolts, the tilting force applied to the screen will be transmitted to the base, causing the wheeled platform to slide or deflect. To compensate for the displacement, repeated adjustments are required, which not only increases installation time but may also cause collision risks in precision scenarios (such as narrow corridors). This can easily lead to unexpected displacement of the interactive robot, forcing the robot to reposition itself, interrupting the workflow, and making the installation process inefficient and inconvenient to operate. Utility Model Content

[0004] The purpose of this invention is to provide an interactive robot that can quickly install screen components on a mobile base, while avoiding accidental displacement of the interactive robot during installation, thereby improving installation efficiency and ease of operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design an interactive robot, including a mobile base, splicing components, and a screen component for interaction; The splicing assembly includes a first magnetic attraction mechanism and a second magnetic attraction mechanism. The first magnetic attraction mechanism is disposed on the movable base, and the second magnetic attraction mechanism is disposed on the screen assembly.

[0006] Optionally, the first magnetic attraction mechanism includes a plurality of first grooves, which are sequentially arranged on the movable base in a circular array, and the second magnetic attraction mechanism is arranged corresponding to the first grooves.

[0007] Optionally, the second magnetic attraction mechanism includes a plurality of second grooves, which are disposed on the screen assembly corresponding to a plurality of first grooves, and magnets are embedded in both the first grooves and the second grooves.

[0008] Optionally, the splicing assembly further includes a support mechanism, a first adjustment mechanism, and a second adjustment mechanism. The support mechanism includes a support plate, a mounting plate, and an adjustment shaft. The first magnetic attraction mechanism is disposed on the surface of the support plate. The support plate is rotatably connected to the mounting plate. The first adjustment mechanism is disposed on the mounting plate and is used to drive the support plate to connect to the adjustment shaft via the second adjustment mechanism. The second adjustment mechanism is used to adjust the pitch angle of the mounting plate.

[0009] Optionally, the first adjustment mechanism includes a first servo motor and a transmission gear. The first servo motor is mounted on a mounting plate, and its output end extends through the mounting plate and connects to the transmission gear. The surface of the bearing plate is provided with a transmission tooth groove corresponding to the transmission gear, and the transmission gear and the transmission tooth groove mesh with each other.

[0010] Optionally, the second adjustment mechanism includes a second servo motor, a support frame, a drive shaft, a drive gear, and a driven gear. The second servo motor is fixedly connected to the support frame. The drive shaft is fixedly connected to the adjustment shaft. The driven gear is fixedly connected to the outer surface of the drive shaft. The drive gear is fixedly connected to the output end of the second servo motor corresponding to the driven gear. The drive gear and the driven gear mesh with each other.

[0011] Optionally, the surface of the carrier disk is provided with a wiring groove and a wiring hole. The wiring hole is located at the center of the carrier disk. One end of the wiring groove communicates with the wiring hole, and the other end extends to the edge of the carrier disk. The wiring groove passes through the midpoint between two of the first grooves.

[0012] Optionally, the movable base includes a chassis and a support rod, one end of which is fixedly connected to the chassis, and the other end of which is rotatably connected to an adjustment shaft through a slot.

[0013] This utility model provides an interactive robot with the following advantages: This interactive robot, through the coordinated arrangement of a first and a second magnetic attraction mechanism, can pre-tighten or directly lock the screen component (i.e., iPad, tablet, or Android tablet) onto the mobile base. Strong magnetic force ensures the screen component remains stable during movement, guaranteeing its stability in use. Furthermore, during installation, the robot guides the screen component to automatically correct its position, avoiding manual adjustments (for example, when installing the screen component onto the mobile base with bolts, the screen component may tilt or transmit a certain degree of manual pushing force, which, when transmitted to the mobile base, can cause it to move, increasing the difficulty of installation). The magnetic attraction of the components brings the mobile base and screen component closer together, allowing for quick installation. It also facilitates rapid replacement of the screen component when needed. In practical use, when the screen component needs to be removed for viewing, it can be directly removed from the mobile base without a cumbersome disassembly process, improving ease of use.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figures 1 to 5 This utility model provides a technical solution: a robot, specifically used in exhibition halls, which is a robot that uses a tablet computer set on a mobile base as a screen, which can improve the convenience of disassembling and installing the screen component, so as to meet the convenience of frequently removing the screen component for handheld viewing in the home.

[0018] Please see Figures 1 to 5 The present invention provides a technical solution: an interactive robot, comprising a mobile base 10, a splicing component 20, and a screen component 30 for interaction; The splicing component 20 includes a first magnetic attraction mechanism 21 and a second magnetic attraction mechanism 22. The first magnetic attraction mechanism 21 is disposed on the movable base 10, and the second magnetic attraction mechanism 22 is disposed on the screen component 30. The movable base 10 and the screen component 30 form a modular magnetic attraction connection through the first magnetic attraction mechanism 21 (base end) and the second magnetic attraction mechanism 22 (screen end) in the splicing component 20. Physical docking is achieved through the magnetic coupling of the first magnetic attraction mechanism 21 and the second magnetic attraction mechanism 22, so that the screen component 30 and the movable base 10 form a rigid connection. The magnetic force between the first magnetic attraction mechanism 21 and the second magnetic attraction mechanism 22 is sufficient to support the purpose of use. The magnetic attraction force simultaneously undertakes the three functions of positioning guidance (i.e., automatically correcting the position between the screen component 30 and the movable base 10), dynamic locking (i.e., anti-vibration and anti-detachment during movement), and rapid decoupling (i.e., one-click separation). This ensures the stability of the screen component 30 when the interactive robot moves, and also realizes efficient operation of zero-thrust installation (i.e., avoiding base displacement) and tool-free replacement. Through the cooperative arrangement of the first magnetic attraction mechanism 21 and the second magnetic attraction mechanism 22, the screen assembly 30 can be pre-tightened on the movable base 10 or directly locked by magnetic attraction. The strong magnetic force ensures that the screen assembly 30 does not wobble during movement, guaranteeing the stability of the screen assembly 30 during use. Furthermore, during the installation process of the screen assembly 30, it can guide the screen assembly 30 to automatically correct its position, avoiding manual fine-tuning. (For example, when the screen assembly 30 is installed on the movable base 10 by bolts, the screen assembly 30 may tilt or transmit a certain degree of manual pushing force.) The artificially generated pushing force is transmitted to the mobile base 10, which will push the mobile base 10 to move, thus increasing the difficulty of installing the screen component 30. Through the magnetic attraction of the splicing component 20, the mobile base 10 and the screen component 30 are brought closer to each other, which can quickly install the screen component 30 on the mobile base 10. At the same time, it is also easy to quickly replace the screen component 30 when it needs to be replaced. In practical use, when it is necessary to remove the screen component 30 for viewing and use, the screen component 30 can be directly removed from the mobile base 10 without a cumbersome disassembly process, which improves the convenience of use.

[0019] In this embodiment, as a preferred solution, the first magnetic attraction mechanism 21 includes a plurality of first grooves 212, which are sequentially arranged on the movable base 10 in a circular array. The second magnetic attraction mechanism 22 is correspondingly arranged with the first grooves 212. The circular array of first grooves 212 on the movable base 10 cooperates with the second magnetic attraction mechanism 22 on the screen assembly 30. After the magnetic attraction force dominates the adsorption, the positioning is strengthened by magnetic interlocking. The screen assembly 30 is guided to accurately fall into place by magnetic force. Furthermore, the circular array layout achieves 360° all-area anti-torsional load. The magnetic attraction can eliminate micro-vibrations during movement and achieve the installation characteristic of adsorption and alignment, thus realizing the integration of positioning accuracy and impact resistance stability.

[0020] In this embodiment, as a preferred solution, the second magnetic attraction mechanism 22 includes a plurality of second grooves 222, which are disposed on the screen assembly 30 corresponding to a plurality of first grooves 212. Magnets are embedded in both the first grooves 212 and the second grooves 222. The second magnetic attraction mechanism 22 (i.e., the second grooves 222) on the screen assembly 30 and the first magnetic attraction mechanism 21 (i.e., the first grooves 212) on the movable base 10 form a mirror complementary interlocking structure. Since both are provided with magnets, and the magnetic poles of the opposite magnets are opposite, the corresponding first grooves 212 and second grooves 222 attract each other by magnetic force. After the initial positioning by magnetic attraction force, mechanical interlocking is achieved by magnets. The mechanical interlocking shares the dynamic load (i.e., shear force) of the first magnetic attraction mechanism 21 and the second magnetic attraction mechanism 22. The ring array layout can make the stress evenly distributed, and while ensuring the positioning accuracy, it can completely eliminate the micro-displacement caused by the movement vibration. Moreover, the disassembly and assembly process still maintains the tool-free operation convenience of one-click assembly and one-click disassembly. The screen assembly 30 includes a screen protective shell and a screen body. The second magnetic attraction mechanism 22 is disposed on one surface of the screen protective shell. The surface of the screen protective shell opposite to the second magnetic attraction mechanism 22 has a receiving groove. The screen protective shell is fitted onto the surface of the screen body through the receiving groove. The screen body can be an iPad, tablet computer, or Android tablet. It is connected to the control module through a built-in connection module. The control module can be disposed in the mobile base 10. The iPad, tablet computer, or Android tablet and the control module for interaction are all existing technologies. They can be connected via Bluetooth, or via a mini-program, software, or other communication protocols (such as serial port). This is only a reference and not described. In this embodiment, it is only to illustrate that the screen body can be detachably disposed on the mobile base 10 through the screen protective shell, and can switch between the regular use of the iPad, tablet computer, or Android tablet and its use as a computing and interaction carrier for robots. Furthermore, the screen protector can have through holes for mounting bolts, allowing bolts to pass through and be used to further secure the first magnetic attraction mechanism 21 and the second magnetic attraction mechanism 22 after they are locked together. This can further improve stability depending on the usage environment and can be used as an alternative.

[0021] Furthermore, the magnetic attraction function on the screen assembly is achieved through a screen protector. The screen protector has a second magnetic attraction mechanism 22 and can also be equipped with a wireless charging module. The wireless charging module is a known technology and is only cited here. It can wirelessly charge an iPad, tablet, or Android tablet installed inside the screen protector.

[0022] In this embodiment, as a preferred option, the splicing assembly 20 further includes a support mechanism 25, a first adjustment mechanism 23, and a second adjustment mechanism 24. The support mechanism 25 includes a support plate 251, a mounting plate 253, and an adjustment shaft 254. A first magnetic attraction mechanism 21 is disposed on the surface of the support plate 251, and the support plate 251 is rotatably connected to the mounting plate 253. The first adjustment mechanism 23 is disposed on the mounting plate 253 and is used to drive the support plate 251 to rotate on the mounting plate 253. The support plate 251 is connected to the adjustment shaft 254 via the second adjustment mechanism 24. The second adjustment mechanism 24 is used to adjust the pitch angle of the mounting plate 253. The support plate 251, rotatably connected to the mounting plate 253, can achieve horizontal rotation, and is adjusted by the first adjustment mechanism 24. The 3-drive system connects the mounting plate 253 with the second adjustment mechanism 24 via the adjustment shaft 254 to control the pitch angle. The carrier plate 251 is installed and spliced ​​with the screen assembly 30 via the first magnetic attraction mechanism 21. The first adjustment mechanism 23 drives the carrier plate 251 to rotate horizontally on the mounting plate 253 (i.e., adjust the horizontal orientation of the screen assembly 30). The second adjustment mechanism 24 is supported by the adjustment shaft 254. The second adjustment mechanism 24 changes the pitch angle of the mounting plate 253 by pushing and pulling the mounting plate 253 (i.e., adjust the tilt angle of the screen assembly 30), forming a two-degree-of-freedom motion chain. This allows the screen assembly 30 to independently adjust its azimuth and pitch angles in a magnetically locked state, adapting to multi-view interaction needs without disassembly.

[0023] In this embodiment, as a preferred option, the first adjustment mechanism 23 includes a first servo motor 231 and a transmission gear 232. The first servo motor 231 is mounted on the mounting plate 253, and its output end extends out of the mounting plate 253 and connects to the transmission gear 232. The surface of the bearing plate 251 has a transmission tooth groove 233 corresponding to the transmission gear 232. The transmission gear 232 and the transmission tooth groove 233 mesh with each other. The first servo motor 231 forms an internal meshing transmission chain with the transmission tooth groove 233 on the surface of the bearing plate 251 through the transmission gear 232. The first servo motor 231, fixed to the mounting plate 253, drives the transmission gear 232 to rotate. The transmission gear 232 meshes with the annular transmission tooth groove 233 radially embedded in the bearing plate 251, converting the servo motor torque into the precise horizontal rotation of the bearing plate 251. The distribution of the annular transmission tooth groove 233 makes the bearing plate 251 evenly stressed, eliminating off-center load jamming (compared to single-point drive). At the same time, the meshing of the transmission gear 232 and the transmission tooth groove 233 can isolate motor vibration, ensuring the stability and angle maintenance of the dynamic adjustment of the screen assembly 30.

[0024] In this embodiment, as a preferred option, the second adjustment mechanism 24 includes a second servo motor 241, a support frame 242, a drive shaft 243, a drive gear 244, and a driven gear 245. The second servo motor 241 is fixedly connected to the support frame 242, the drive shaft 243 is fixedly connected to the adjustment shaft 254, the driven gear 245 is fixedly connected to the outer surface of the drive shaft 243, and the drive gear 244 is fixedly connected to the output end of the second servo motor 241 corresponding to the driven gear 245. The drive gear 244 and the driven gear 245 mesh with each other. First, the support frame 242 is rotatably connected to the outer surface of the drive shaft 243, meaning the support frame 242 can rotate on the drive shaft 243. Second, the second servo motor 241 is fixedly connected to the support frame 242, and the second multi-stage can drive the drive gear 244 to rotate. Through the meshing connection between the drive gear 244 and the driven gear 245, the torque of the drive gear 244 when rotating can be converted into the support frame 242 rotating along the outer surface of the drive shaft 243. Furthermore, the mounting plate 253 is fixedly connected to the support frame 242, and the support frame 242 drives the mounting plate 253 to rotate, meaning it can be considered that the support frame 242 drives the mounting plate 253 to flip, which can adjust the pitch angle of the bearing plate 251. The support frame 243 is fixedly connected to the adjusting shaft 254, and the adjusting shaft 254 provides support for the drive shaft 243.

[0025] In this embodiment, as a preferred solution, the surface of the support disk 251 is provided with a cable tray 256 and a wiring hole 257. The wiring hole 257 is opened at the axis of the support disk 251. One end of the cable tray 256 communicates with the wiring hole 257, and the other end extends to the edge of the support disk 251. The cable tray 256 passes through the midpoint between two of the first grooves 212. With the cable tray 256 and the wiring hole 257, the extension direction of the cable tray 256 is parallel to the extension direction of the screen assembly 30. With the wiring hole 257, the power end of the charging cable can pass through the wiring hole for connection. The transition section of the charging cable can be placed in the cable tray 256 to avoid messy lines or interference with the rotation of the carrier plate 251. Furthermore, the charging component can be of the cigarette lighter socket type, that is, the same type as the vehicle 12V power socket. It can rotate to conduct electricity. The principle is an iron sleeve and a conductive block. The conductive block is connected to the charging cable and is set in the wiring hole 257. It can rotate with the carrier plate 251. The iron sleeve is embedded in the mounting plate 253 corresponding to the wiring hole 257. These are all existing known technologies and are only briefly described.

[0026] In this embodiment, as a preferred option, the movable base 10 includes a chassis 11 and a support rod 12. One end of the support rod 12 is fixedly connected to the chassis 11, and the other end of the support rod 12 is rotatably connected to the adjustment shaft 254 through an opening groove. The chassis 11 can be moved by means of the chassis 11. The chassis 11 is equipped with a control module and a caster wheel at the bottom. These are known technologies and are only referenced here. The support rod 12 is used to support the adjustment shaft 254. The adjustment shaft 254 can rotate within the support rod 12. By rotating the adjustment shaft 254 within the support rod 12, the direction of the bearing plate 251 can be adjusted.

[0027] More specifically, the charging component can also be a long charging cable. After the long charging cable passes through the wiring hole 257, the mounting plate 253 has a corresponding through hole for the long charging cable to pass through. After passing through the mounting plate 253, the long charging cable continues to pass through the adjusting shaft 254 and the support rod 12 and connects to the power supply module on the chassis 11. The chassis 11 is also equipped with a battery (i.e., the power supply module). The long charging cable is electrically connected to the battery (i.e., the power supply module). This is a known technology, and it is only used here without any improvement. It will not be described in detail.
